Subject: [POWERPC] Add -fno-stack-protector to BOOTCFLAGS in
 arch/powerpc/boot/Makefile.

I got some undefined references to __stack_chk_fail in
arch/powerpc/boot/stdio.o and arch/powerpc/boot/prom.o when I was trying
to build a kernel on Ubuntu Edgy Eft - which includes Stack Smashing
Protection.

This patch adds -fno-stack-protector to BOOTCFLAGS in
arch/powerpc/boot/Makefile (why does BOOTCFLAGS depend on HOSTCFLAGS and
not CFLAGS?).

Regards,
Niels Kristian Bech Jensen

Subject: [POWERPC] fix up front-LED Kconfig

Rather long patch, apparently no one has updated the pmac32_defconfig in
a while.

Subject: [POWERPC] Workaround Pegasos incorrect ISA "ranges"

The Pegasos firmware doesn't create a valid "ranges" property for the
ISA bridge, thus causing translation of ISA addresses and IO ports to
fail. This fixes it, thus re-enabling proper early serial console to
work on Pegasos.

Subject: [POWERPC] Fix non-MPIC CHRPs with CONFIG_SMP set

Pseudo-CHRP machines like Pegasos without an MPIC would crash at boot if
CONFIG_SMP was set because the "smp_ops" pointer was set to MPIC related
ops unconditionally. This patch makes it NULL on machines that don't
support SMP and provides proper default behaviour in the callers when
smp_ops is NULL.

Subject: [POWERPC] Fix legacy_serial.c error handling on 32 bits

The code in legacy_serial.c wouldn't properly compare OF translation
results against OF_BAD_ADDR as it's using a phys_addr_t which is 32
bits on some 32-bit powerpc platforms. This fixes it by always using
a u64 which is what is returned by the OF parsing routines. It also
makes translation failure harmless for ISA serial ports.  If they
can't translate, we can't use the UART early, but we can still let the
8250 driver use it later on by using IO port accessors.

The support for Briq machines has been floating around as patches for

Some of this is based on initial code provided by Karsten Jeppesen
<karsten@jeppesens.com> and mostly rewritten from scratch by me.

From 73ea6959b11821ba5ade77fb1d3d4aed52be3b67 Mon Sep 17 00:00:00 2001

Subject: [POWERPC] More offb/bootx fixes

There were still some issues with offb when BootX doesn't provide a
proper display node, this fixes them.  This also re-instates the
palette hacks that were disabled a couple of kernel versions ago when
I converted to the new OF parsing, and shuffles some functions around
to avoid prototypes.

Subject: [POWERPC] Fix mem= handling when the memory limit is > RMO size

There's a bug in my cleaned up mem= handling, if the memory limit is
larger than the RMO size we'll erroneously enlarge the RMO size.

Fix is to only change the RMO size if the memory limit is less than
the current RMO value.

Subject: [POWERPC] Xserve G5 thermal control fixes

The thermal control for the Xserve G5s had a few issues. For one, the
way to program the RPM fans speeds into the FCU is different between it
and the desktop models, which I didn't figure out until recently, and it
was missing a control loop for the slots fan, running it too fast.  Both
of those problems were causing the machine to be much more noisy than
necessary.  This patch also changes the fixed value of the slots fan for
desktop G5s to 40% instead of 50%.  It seems to still have a pretty good
airflow that way and is much less noisy.

Subject: [POWERPC] Add cpufreq support for Xserve G5

The Xserve G5 are capable of frequency switching like other desktop G5s.
This enables it. It also fix a Kconfig issue which prevented from
building the G5 cpufreq support if CONFIG_PMAC_SMU was not set (the
first version of that driver only worked with SMU based macs, but this
isn't the case anymore).

Subject: [POWERPC] Remove linux,device properties

The linux,device property isn't used anywhere within the kernel, and
since it's a kernel pointer, it's a little useless for userspace.

This change removes the code to create this property in
of_device_register.

Built for pmac32.

- * We have two different locks in the bcm43xx driver.
- * => bcm->mutex:    General sleeping mutex. Protects struct bcm43xx_private
- *                   and the device registers.
- * => bcm->irq_lock: IRQ spinlock. Protects against IRQ handler concurrency.
- *
- * We have three types of helper function pairs to utilize these locks.
- *     (Always use the helper functions.)
- * 1) bcm43xx_{un}lock_noirq():
- *     Takes bcm->mutex. Does _not_ protect against IRQ concurrency,
- *     so it is almost always unsafe, if device IRQs are enabled.
- *     So only use this, if device IRQs are masked.
- *     Locking may sleep.
- *     You can sleep within the critical section.
- * 2) bcm43xx_{un}lock_irqonly():
- *     Takes bcm->irq_lock. Does _not_ protect against
- *     bcm43xx_lock_noirq() critical sections.
- *     Does only protect against the IRQ handler path and other
- *     irqonly() critical sections.
- *     Locking does not sleep.
- *     You must not sleep within the critical section.
- * 3) bcm43xx_{un}lock_irqsafe():
- *     This is the cummulative lock and takes both, mutex and irq_lock.
- *     Protects against noirq() and irqonly() critical sections (and
- *     the IRQ handler path).
- *     Locking may sleep.
- *     You must not sleep within the critical section.

From 2087da5dc12c497123d5fb8949ceed9021b673ec Mon Sep 17 00:00:00 2001
From: Michael Buesch <mb@bu3sch.de>
Date: Wed, 28 Jun 2006 20:17:57 +0200
Subject: [PATCH] bcm43xx: voluntary preemtion in the calibration loops

This patch adds voluntary preemption points into the
PHY calibration loops to allow non-CONFIG_PREEMPT machines
to not suffer from huge delays.
CONFIG_PREEMPT machines are already fine, because all this
code is run in non-atomic process context.

Subject: [PATCH] bcm43xx: improved statistics

This patch improves the statistics returned from
bcm43xx_get_wireless_stats. The signal level comes from smoothing the
"rssi" value returned by the firmware after it is converted into a
dBm value by the driver. The quality value is a hack derived from the
smoothed level and an assumed RX_POWER_MAX of -10 dBM. The noise value
is still the one calculated from the clean-room formula. On my system,
this is roughly -65 dBm, which seems too high.

The revised version uses the ieee80211 spinlock to protect traversing
of the network list.

Subject: [POWERPC] iseries: Use device tree /system-id in /proc/iSeries/config

We export a bunch of info in /proc/iSeries/config. Currently we pull it
directly out of some iSeries specific structs, but we could use the device
tree instead, this saves decoding it twice and is a little neater.

e2a() was formally used by lparcfg, and so had to be exported, but isn't
anymore, so don't.

e2a() and strne2a() can both be static, and __init.

And e2a can be made much more concise if we use x ... y case labels, while
we're there add support for lower case letters.

Subject: [POWERPC] iseries: Make ItExtVpdPanel private to iSeries

No one outside platforms/iseries needs ItExtVpdPanel anymore, so move
it in there. It used to be needed by lparcfg, and so was exported, but
isn't needed anymore, so unexport it.

Subject: [POWERPC] iseries: Fix a compiler warning in
 platforms/iseries/vpdinfo.c

iSeries_Get_Location_Code() has error paths, but currently returns void, so
give it a return code and only print the output if it returns successfully.
Gcc isn't smart enough to be quiet though, so set frame to 0 to shut it up.

Subject: [POWERPC] Fix a compiler warning in mm/tlb_64.c

The compiler doesn't understand that BUG() never returns, so complains that
psize isn't set. Just set it to the normal value, which seems to produce nice
code and keeps gcc happy.

Subject: [POWERPC] iseries: A new iSeries console

This driver uses the hvc_console.c infrastructure that is used by the
pSeries virtual and RTAS consoles.  This will allow us to make viocons.c
obsolete and is another step along the way to a combined kernel (as
viocons could not coexist with CONFIG_VT).

From 4e9e95a3554e98e7383a3591283ffcd850c9ef48 Mon Sep 17 00:00:00 2001
From: Stephen Rothwell <sfr@canb.auug.org.au>

Subject: [POWERPC] Make the hvc_console output buffer size settable

So the iSeries console will be faster since it can send up to 200 bytes at
a time to the Hypervisor.  This only affects the tty part of the console,
the console writes are still in 16 byte lots.

Subject: [PATCH] The redefinition of ahci_start_engine() and
 ahci_stop_engine()

- Make ahci_start_engine() and ahci_stop_engine() more consistent with
  AHCI spec 1.1
- Change their input parameter from ap to port_mmio
- Update the existing users of ahci_start_engine() and ahci_stop_engine()

control almost automagically. User report a different story, so
let's try to twiddle the mii registers.

From bcf0bf90cd9e9242b66e0563b6a8c8db2e4c262c Mon Sep 17 00:00:00 2001

Subject: r8169: sync with vendor's driver

- add several PCI ID for the PCI-E adapters ;
- new identification strings ;
- the RTL_GIGA_MAC_VER_ defines have been renamed to closely match the
  out-of-tree driver. It makes the comparison less hairy ;
- various magic ;
- the PCI region for the device with PCI ID 0x8136 is guessed.
  Explanation: the in-kernel Linux driver is written to allow MM register
  accesses and avoid the IO tax. The relevant BAR register was found at
  base address 1 for the plain-old PCI 8169. User reported lspci show that
  it is found at base address 2 for the new Gigabit PCI-E 816{8/9}.
  Typically:
  01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.: Unknown device 8168 (rev 01)
          Subsystem: Unknown device 1631:e015
          Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
          Status: Cap+ 66Mhz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR-
          Latency: 0, cache line size 20
          Interrupt: pin A routed to IRQ 16
          Region 0: I/O ports at b800 [size=256]
          Region 2: Memory at ff7ff000 (64-bit, non-prefetchable) [size=4K]
          ^^^^^^^^
  So far I have not received any lspci report for the 0x8136 and
  Realtek's driver do not help: be it under BSD or Linux, their r1000 driver
  include a USE_IO_SPACE #define but the bar address is always hardcoded
  to 1 in the MM case. :o/
- the 8168 has been reported to require an extra alignment for its receive
  buffers. The status of the 8167 and 8136 is not known in this regard.

Subject: [PATCH] prism54: update to WE-19 for WPA support

Add WE-19 capabilities to prism54 fullmac driver so that it supports the
necessary Wireless Extensions WPA calls.  Convert reporting of WPA/RSN
Generic Information Elements to IWEVGENIE rather than pre-WE-19
IWEVCUSTOM as well.

Subject: [PATCH] ieee80211: small ERP handling additions

This adds a flag to the ieee80211_network structure which indicates whether
the stored erp_value is valid (a check against 0 is not enough, since an ERP
of 0 is valid and very meaningful).

I also added the ERP IE bit-definitions to ieee80211.h.

This is needed by some upcoming softmac patches.

Subject: [PATCH] softmac: ERP handling and driver-level notifications

This patch implements ERP handling in softmac so that the drivers can support
protection and preambles properly.

I added a new struct, ieee80211softmac_bss_info, which is used for
BSS-dependent variables like these.

A new hook has been added (bssinfo_change), which allows the drivers to be
notified when anything in bssinfo changes.

I modified the txrates_change API to match the bssinfo_change API. The
existing one is a little messy and the usefulness of providing the old rates
is questionable (and can be implemented at driver level if really necessary).
No drivers are using this API (yet), so this should be safe.

Subject: [PATCH] ieee80211: Make ieee80211_rx_any usable

ieee80211_rx_any is new to 2.6.18-rc1, even though it appears this function
was never completed:

http://lists.sipsolutions.net/pipermail/softmac-dev/2006-February/000103.html

This patch changes ieee80211_rx_any to always claim the skb, which avoids
further driver complexity and the possibility of leaking management frames.
It also exports the function so that people can actually use it.

Subject: [PATCH] bcm43xx: suspend MAC while executing long pwork

Suspend MAC (and make MAC-suspend refcounting) when doing
long periodic work.
On long periodic work, we disable IRQs on the device, so
we don't want the MAC to stay operating and probably miss
packets due do non-delivery of interrupts.

Subject: [PATCH] bcm43xx: init routine rewrite

Rewrite of the bcm43xx initialization routines.
This fixes several issues:
* up-down-up-down-up... stale data issue
  (May fix some DHCP issues)
* Fix the init vs IRQ handler race (and remove the workaround)
* Fix init for cards with multiple cores (APHY)
  As softmac has no internal PHY handling (unlike dscape),
  this adds the file "phymode" to sysfs.
  The active PHY can be selected by writing either a, b or g
  to this file. Current PHY can be determined by reading from it.
* Fix the controller restart code.
  Controller restart can now also be triggered through
  echo 1 > /debug/bcm43xx/ethX/restart

From 27be44ff8ee29e945adad226cc360c9278239d17 Mon Sep 17 00:00:00 2001
From: Larry Finger <Larry.Finger@lwfinger.net>
Date: Fri, 14 Jul 2006 15:42:17 -0500
Subject: [PATCH] bcm43xx: improved statistics

This minor patch for wireless-2.6 (softmac) adjusts the parameters of
the wireless statistics to improve the display of programs such as the
"Wireless Network Information" applet of KDE. Thanks to Dan Williams
and Jean Tourrilhes for valuable help in setting up the return of
info in dBm.

Subject: [PATCH] qla3xxx NIC driver

This is a complementary network driver for our ISP4XXX parts.

There is a concurrent effort underway to get the iSCSI driver (qla4xxx)
integrated upstream as well.

I have been through several iterations with the linux-netdev list and have had
much response from Stephen Hemminger.

- Built and tested using kernel 2.6.17-rc4.

- The chip supports two ethernet and two iSCSI functions.

- The functions ql_sem_lock, ql_sem_spinlock, ql_sem_unlock, and
  ql_wait_for_drvr_lock are used to protect resources that are shared across
  the network and iSCSI functions.  This protection is mostly during chip
  initialization and resets, but also include link management.

- The PHY/MII are not exported through ethtool due to the fact that the
  iSCSI function will control the common link at least 50% of the time.

This driver has been through several iterations on the netdev list and we feel
this driver is ready for inclusion in the upstream kernel.

It has been built and tested on x86 and PPC64 platforms.

From f82a9352f6b955d1dd9adc1124d6796be2c147df Mon Sep 17 00:00:00 2001
From: Stephen Hemminger <shemminger@osdl.org>

Subject: [PATCH] forcedeth: coding style cleanups

Fix the coding style of the nForce Ethernet driver.
 - typedef's should not be used
 - variable names should not be capitialized
 - structure tags should be lower case
 - add whitespace near keywords
 - don't add paren's to switch cases
 - remove paren's from return
 - don't use __constant_ntohs unless necessary.

Subject: [PATCH] ahci: relocate several internal functions

* move ahci_port_start/stop() below EH functions.  This makes ahci
  more consistent with other drivers and makes prototypes for
  ahci_start/stop_engine() unnecessary.

* swap positions between ahci_start_engine() and ahci_stop_engine()
  for readability.

Subject: [PATCH] ahci: simplify ahci_start_engine()

Simplify ahci_start_engine() by killing prerequisite condition checks.
Rationales are..

* No user checks error return from ahci_start_engine()

* Code flow guarantees the prerequisite conditions unless the
  controller is malfunctioning.  In such cases, the driver had chances
  to learn about the problem _before_ calling this function.

* Closely related to the above two, driver calls into this function
  even when prerequisites fail hoping for the best.

Basically, ahci_start_engine() should only do the operation itself.
It isn't the right place to check for prerequisites.

Subject: [PATCH] libata: improve driver initialization and deinitialization

Implement ahci_[de]init_port() and use it during initialization and
de-initialization.  ahci_[de]init_port() are supersets of what used to
be done during driver [de-]initialization.  This patch makes the
following behavior changes.

* Per-port IRQ mask is cleared on driver load as done in other
  drivers.  The mask will be configured properly during probe.

* During init_one(), HOST_IRQ_STAT is cleared after masking port IRQs
  such that there is no race window.

* CMD_SPIN_UP is cleared during init_one() instead of being set.  It
  is set in port_start().  This is more consistent with overall
  structure of initialization.  Note that CMD_SPIN_UP simply controls
  PHY activation.

* Slumber and staggered spin-up are handled properly.

* All init/deinit operations are done in step-by-step manner as
  described in the spec instead of issued as single merged command.

Original implementation is from Zhao, Forrest <forrest.zhao@intel.com>

Subject: [PATCH] ahci: separate out ahci_reset_controller() and
 ahci_init_controller()

Separate out ahci_reset_controller() and ahci_init_controller() from
ata_host_init().  These will be used by PM callbacks.  This patch
doesn't introduce any behavior change.

Subject: [POWERPC] Constify & voidify get_property()

Now that get_property() returns a void *, there's no need to cast its
return value. Also, treat the return value as const, so we can
constify get_property later.

powerpc core changes.

From 954a46e2d5aec6f59976ddeb1d232b486e59b54a Mon Sep 17 00:00:00 2001
From: Jeremy Kerr <jk@ozlabs.org>
Date: Wed, 12 Jul 2006 15:39:43 +1000
Subject: [POWERPC] pseries: Constify & voidify get_property()

Now that get_property() returns a void *, there's no need to cast its
return value. Also, treat the return value as const, so we can
constify get_property later.

pseries platform changes.

Built for pseries_defconfig

Subject: [POWERPC] iseries: Constify & voidify get_property()

Now that get_property() returns a void *, there's no need to cast its
return value. Also, treat the return value as const, so we can
constify get_property later.

Subject: [POWERPC] maple: Constify & voidify get_property()

Now that get_property() returns a void *, there's no need to cast its
return value. Also, treat the return value as const, so we can
constify get_property later.

maple platform changes.

Subject: [POWERPC] Make get_property() return a const void *

Previous changes have treated the return values of get_property as
const, so now we can make the actual change to get_property(). There
shouldn't be a need to cast the return values anymore.

We will now get compiler warnings when property values are assigned to
a non-const variable.

If properties need to be updated, there's still the of_find_property
function.

Built for cell_defconfig, chrp32_defconfig, g5_defconfig,
iseries_defconfig, maple_defconfig, pmac32_defconfig, ppc64_defconfig
and pseries_defconfig.

From: Anton Blanchard <anton@samba.org>
Date: Wed, 19 Jul 2006 08:01:28 +1000
Subject: [POWERPC] clean up pseries hcall interfaces

Our pseries hcall interfaces are out of control:

	plpar_hcall_norets
	plpar_hcall
	plpar_hcall_8arg_2ret
	plpar_hcall_4out
	plpar_hcall_7arg_7ret
	plpar_hcall_9arg_9ret

Create 3 interfaces to cover all cases:

	plpar_hcall_norets:	7 arguments no returns
	plpar_hcall:		6 arguments 4 returns
	plpar_hcall9:		9 arguments 9 returns

There are only 2 cases in the kernel that need plpar_hcall9, hopefully
we can keep it that way.

Pass in a buffer to stash return parameters so we avoid the &dummy1,
&dummy2 madness.

Subject: [SCSI] areca sysfs fix

Remove sysfs_remove_bin_file() return-value checking from the areca driver.

There's nothing a driver can do if sysfs file removal fails, so we'll soon be
changing sysfs_remove_bin_file() to internally print a diagnostic and to
return void.

Subject: [SCSI] arcmsr: fix up sysfs values

The sysfs files in arcmsr are non-standard in that they aren't simple
filename value pairs, the values actually contain preceeding text which
would have to be parsed.  The idea of sysfs files is that the file name
is the description and the contents is a simple value.

Fix up arcmsr to conform to this standard.

Subject: [PATCH] sky2: status interrupt handling improvement

More changes to prevent losing status and causing hangs.
The hardware is smarter than I gave it credit for.
Clearing the status IRQ causes the status state machine to
toggle an IRQ if needed and post any more transmits.

Subject: [SCSI] advansys pci tweaks.

Remove a lot of duplicate #defines from the advansys driver,
and make them look like PCI IDs as defined elsewhere in the kernel.
Also add a module table so that it automatically gets picked up
by tools relying on modinfo output (like say, distro installers).

Subject: [SCSI] DAC960: PCI id table fixup

The PCI ID table in the DAC960 driver conflicts with some devices
that use the ipr driver. All ipr adapters that use this chip
have an IBM subvendor ID and all DAC960 adapters that use this
chip have a Mylex subvendor id.

Subject: [SCSI] scsi_queue_work() documented return value is incorrect

If you examine the queue_work() routine you'll see that it returns
1 on success, 0 if the work is already queued.

This patch corrects the source code documentation for the
scsi_queue_work function.

Subject: [SCSI] ipr: Properly handle IOA recovered errors

The ipr driver currently translates adapter recovered errors
to DID_ERROR. This patch fixes this to translate these
errors to success instead.

Subject: [SCSI] Improve inquiry printing

 - Replace scsi_device_types array API with scsi_device_type function API.
   Gets rid of a lot of common code, as well as being easier to use.
 - Add the new device types in SPC4 r05a, and rename some of the older ones.
 - Reformat the printing of inquiry data; now fits on one line and
   includes PQ.

I think I've addressed all the feedback from the previous versions.  My
current test box prints:

scsi 2:0:1:0: Direct access     HP 18.2G ATLAS10K3_18_SCA HP05 PQ: 0 ANSI: 2

Subject: [SCSI] fix up short inquiry printing

A recent drivers base commit:

Caused the bus to be added to dev_printk, so now our SCSI inquiry short
messages print like this:

scsiscsi 2:0:0:0: Direct access     IBM-ESXS ST973401SS       B519 PQ: 0 ANSI: 5

Just remove the "scsi" from the sdev_printk to compensate.

Subject: [POWERPC] Rewrite the PPC 86xx IRQ handling to use Flat Device Tree

IRQ setup now comes from the Flat Device Tree and use the new generic
IRQ code.  Fixed the fsl_soc.c IRQ OF interrupt node parsing.
Removed some unused MPC86xx macro definition.

Subject: [POWERPC] Turn on tigon3 support in maple_defconfig

I think that most people who use maple_defconfig are doing so for a JS21,
so it might make sense to turn Tigon3 support on by default.

Built and booted on a JS21.

We don't have much in the way of doc comments, but some of those we do have
don't work because they start with "/***" or "/*", not "/**" which is what
kernel-doc requires.

Subject: [POWERPC] Remove flush_dcache_all export

Removes the flush_dcache_all export for non coherent platforms.
We removed the last in-kernel user of this years ago in arch/ppc
so it no longer serves a purpose. Plus, it breaks the build
at the moment.

Subject: [POWERPC] Implement SLB shadow buffer

This adds a shadow buffer for the SLBs and regsiters it with PHYP.
Only the bolted SLB entries (top 3) are shadowed.

The SLB shadow buffer tells the hypervisor what the kernel needs to
have in the SLB for the kernel to be able to function.  The hypervisor
can use this information to speed up partition context switches.

Subject: [PATCH] forcedeth: move mac address setup/teardown

This patch moves the mac address setup/teardown to the
nv_probe/nv_remove functions. This fixes WOL wakeup since on nv_close we
would reverse the mac address. Also, bonding driver will reset address
after nv_close is called.

This patch will correct the mac address and set a flag to indicate that
it is already corrected in case nv_probe is called again. For example,
when you use kexec to restart the kernel.

Subject: [PATCH] forcdeth: revised NAPI support

Revised version of the forcedeth NAPI support.
This version is based against netdev-2.6#upstream
(after the MAC patches from Ayaz today).

Can't use nv_disable_hw_interrupts because NAPI only wants to
mask off receive irq's and leave the others alone.

Subject: [PATCH] libata: Add support for SATA attachment to SAS adapters

The following patch enhances libata to allow SAS device drivers
to utilize libata to talk to SATA devices. It introduces some
new APIs which allow libata to be used without allocating a
virtual scsi host.

New APIs:

ata_sas_port_alloc - Allocate an ata_port
ata_sas_port_init - Initialize an ata_port (probe device, etc)
ata_sas_port_destroy - Free an ata_port allocated by ata_sas_port_alloc
ata_sas_slave_configure - configure scsi device
ata_sas_queuecmd - queue a scsi command, similar to ata_scsi_queuecomand

These new APIs can be used either directly by a SAS LLDD or could be used
by the SAS transport class.

Possible usage for a SAS LLDD would be:

scsi_scan_host
	target_alloc
		ata_sas_port_alloc
	slave_alloc
		ata_sas_port_init
	slave_configure
		ata_sas_slave_configure

Commands received by the LLDD for SATA devices would call ata_sas_queuecmd.

Device teardown would occur with:

slave_destroy
	port_disable
target_destroy
	ata_sas_port_destroy

libata naming got stuck in the middle of a Great Renaming:

	ata_host -> ata_port
	ata_host_set -> ata_host

To eliminate confusion, let's just give up for now, and simply ensure
that things are internally consistent.

Subject: [PATCH] libata: implement per-dev xfermask

Implement per-dev xfermask.  libata used to determine xfermask
per-port - the fastest mode of the slowest device on the port.  This
patch enables per-dev xfermask.

Original patch is from Alan Cox <alan@redhat.com>.  The following
changes are made by me.

* simplex warning message is added
* remove disabled device handling code which is never invoked
  (originally for choosing port-wide lowest PIO mode)

Subject: [PATCH] libata: rework legacy handling to remove much of the cruft

Kill host_set->next
Fix simplex support
Allow per platform setting of IDE legacy bases

Some of this can be tidied further later on, in particular all the
legacy port gunge belongs as a PCI quirk/PCI header decode to understand
the special legacy IDE rules in the PCI spec.

Longer term Jeff also wants to move the request_irq/free_irq out of core
which will make this even cleaner.

tj: folded in three followup patches - ata_piix-fix, broken-arch-fix
and fix-new-legacy-handling, and separated per-dev xfermask into
separate patch preceding this one.  Folded in fixes are...

* ata_piix-fix: fix build failure due to host_set->next removal
* broken-arch-fix: add missing include/asm-*/libata-portmap.h
* fix-new-legacy-handling:
	* In ata_pci_init_legacy_port(), probe_num was incorrectly
          incremented during initialization of the secondary port and
          probe_ent->n_ports was incorrectly fixed to 1.

	* Both legacy ports ended up having the same hard_port_no.

	* When printing port information, both legacy ports printed
	  the first irq.

Subject: [PATCH] libata: implement dummy port

Implement dummy port which can be requested by setting appropriate bit
in probe_ent->dummy_port_mask.  The dummy port is used as placeholder
for stolen legacy port.  This allows libata to guarantee that
index_of(ap) == ap->port_no == actual_device_port_no, and thus to
remove error-prone ap->hard_port_no.

As it's used only when one port of a legacy controller is reserved by
some other entity (e.g. IDE), the focus is on keeping the added *code*
complexity at minimum, so dummy port allocates all libata core
resources and acts as a normal port.  It just has all dummy port_ops.

This patch only implements dummy port.  The following patch will make
libata use it for stolen legacy ports.

Subject: [ATA] Increase lba48 max-sectors from 200 to 256.

Also, moved ATA_MAX_SECTORS and ATA_MAX_SECTORS_LBA48 from
linux/libata.h to linux/ata.h, now that they truly reflect the standard
(well... mostly; note TODO comment).

This changes the performance profile (and potential bug profile)
for a bunch of drivers, so be wary.

+ *  libata documentation is available via 'make {ps|pdf}docs',
+ *  as Documentation/DocBook/libata.*
+ *
+ *  Hardware documentation available at http://developer.intel.com/
+ *
+ * Documentation
+ *	Publically available from Intel web site. Errata documentation
+ * is also publically available. As an aide to anyone hacking on this
+ * driver the list of errata that are relevant is below.going back to
+ * PIIX4. Older device documentation is now a bit tricky to find.
+ *
+ * The chipsets all follow very much the same design. The orginal Triton
+ * series chipsets do _not_ support independant device timings, but this
+ * is fixed in Triton II. With the odd mobile exception the chips then
+ * change little except in gaining more modes until SATA arrives. This
+ * driver supports only the chips with independant timing (that is those
+ * with SITRE and the 0x44 timing register). See pata_oldpiix and pata_mpiix
+ * for the early chip drivers.
+ *
+ * Errata of note:
+ *
+ * Unfixable
+ *	PIIX4    errata #9	- Only on ultra obscure hw
+ *	ICH3	 errata #13     - Not observed to affect real hw
+ *				  by Intel
+ *
+ * Things we must deal with
+ *	PIIX4	errata #10	- BM IDE hang with non UDMA
+ *				  (must stop/start dma to recover)
+ *	440MX   errata #15	- As PIIX4 errata #10
+ *	PIIX4	errata #15	- Must not read control registers
+ * 				  during a PIO transfer
+ *	440MX   errata #13	- As PIIX4 errata #15
+ *	ICH2	errata #21	- DMA mode 0 doesn't work right
+ *	ICH0/1  errata #55	- As ICH2 errata #21
+ *	ICH2	spec c #9	- Extra operations needed to handle
+ *				  drive hotswap [NOT YET SUPPORTED]
+ *	ICH2    spec c #20	- IDE PRD must not cross a 64K boundary
+ *				  and must be dword aligned
+ *	ICH2    spec c #24	- UDMA mode 4,5 t85/86 should be 6ns not 3.3
+ *
+ * Should have been BIOS fixed:
+ *	450NX:	errata #19	- DMA hangs on old 450NX
+ *	450NX:  errata #20	- DMA hangs on old 450NX
+ *	450NX:  errata #25	- Corruption with DMA on old 450NX
+ *	ICH3    errata #15      - IDE deadlock under high load
+ *				  (BIOS must set dev 31 fn 0 bit 23)
+ *	ICH3	errata #18	- Don't use native mode

- *  libata documentation is available via 'make {ps|pdf}docs',

- *
- *  Hardware documentation available at http://developer.intel.com/
- *
- * Documentation
- *	Publically available from Intel web site. Errata documentation
- * is also publically available. As an aide to anyone hacking on this
- * driver the list of errata that are relevant is below.going back to
- * PIIX4. Older device documentation is now a bit tricky to find.
- *
- * The chipsets all follow very much the same design. The orginal Triton
- * series chipsets do _not_ support independant device timings, but this
- * is fixed in Triton II. With the odd mobile exception the chips then
- * change little except in gaining more modes until SATA arrives. This
- * driver supports only the chips with independant timing (that is those
- * with SITRE and the 0x44 timing register). See pata_oldpiix and pata_mpiix
- * for the early chip drivers.
- *
- * Errata of note:
- *
- * Unfixable
- *	PIIX4    errata #9	- Only on ultra obscure hw
- *	ICH3	 errata #13     - Not observed to affect real hw
- *				  by Intel
- *
- * Things we must deal with
- *	PIIX4	errata #10	- BM IDE hang with non UDMA
- *				  (must stop/start dma to recover)
- *	440MX   errata #15	- As PIIX4 errata #10
- *	PIIX4	errata #15	- Must not read control registers
- * 				  during a PIO transfer
- *	440MX   errata #13	- As PIIX4 errata #15
- *	ICH2	errata #21	- DMA mode 0 doesn't work right
- *	ICH0/1  errata #55	- As ICH2 errata #21
- *	ICH2	spec c #9	- Extra operations needed to handle
- *				  drive hotswap [NOT YET SUPPORTED]
- *	ICH2    spec c #20	- IDE PRD must not cross a 64K boundary
- *				  and must be dword aligned
- *	ICH2    spec c #24	- UDMA mode 4,5 t85/86 should be 6ns not 3.3
- *
- * Should have been BIOS fixed:
- *	450NX:	errata #19	- DMA hangs on old 450NX
- *	450NX:  errata #20	- DMA hangs on old 450NX
- *	450NX:  errata #25	- Corruption with DMA on old 450NX
- *	ICH3    errata #15      - IDE deadlock under high load
- *				  (BIOS must set dev 31 fn 0 bit 23)
- *	ICH3	errata #18	- Don't use native mode

- *	sil_dev_config - Apply device/host-specific errata fixups

- *
- *	After the IDENTIFY [PACKET] DEVICE step is complete, and a
- *	device is known to be present, this function is called.
- *	We apply two errata fixups which are specific to Silicon Image,
- *	a Seagate and a Maxtor fixup.
- *
- *	For certain Seagate devices, we must limit the maximum sectors
- *	to under 8K.
- *
- *	For certain Maxtor devices, we must not program the drive
- *	beyond udma5.
- *
- *	Both fixups are unfairly pessimistic.  As soon as I get more
- *	information on these errata, I will create a more exhaustive
- *	list, and apply the fixups to only the specific
- *	devices/hosts/firmwares that need it.
- *
- *	20040111 - Seagate drives affected by the Mod15Write bug are blacklisted
- *	The Maxtor quirk is in the blacklist, but I'm keeping the original
- *	pessimistic fix for the following reasons...
- *	- There seems to be less info on it, only one device gleaned off the
- *	Windows	driver, maybe only one is affected.  More info would be greatly
- *	appreciated.
- *	- But then again UDMA5 is hardly anything to complain about

Try to make dbs_check_cpu() call on all CPUs at the same jiffy.
This will help when multiple cores share P-states via Hardware Coordination.

Subject: [CPUFREQ][2/2] ondemand: updated add powersave_bias tunable

ondemand selects the minimum frequency that can retire
a workload with negligible idle time -- ideally resulting in the highest
performance/power efficiency with negligible performance impact.

But on some systems and some workloads, this algorithm
is more performance biased than necessary, and
de-tuning it a bit to allow some performance impact
can save measurable power.

This patch adds a "powersave_bias" tunable to ondemand
to allow it to reduce its target frequency by a specified percent.

By default, the powersave_bias is 0 and has no effect.
powersave_bias is in units of 0.1%, so it has an effective range
of 1 through 1000, resulting in 0.1% to 100% impact.

In practice, users will not be able to detect a difference between
0.1% increments, but 1.0% increments turned out to be too large.
Also, the max value of 1000 (100%) would simply peg the system
in its deepest power saving P-state, unless the processor really has
a hardware P-state at 0Hz:-)

For example, If ondemand requests 2.0GHz based on utilization,
and powersave_bias=100, this code will knock 10% off the target
and seek  a target of 1.8GHz instead of 2.0GHz until the
next sampling.  If 1.8 is an exact match with an hardware frequency
we use it, otherwise we average our time between the frequency
next higher than 1.8 and next lower than 1.8.

Note that a user or administrative program can change powersave_bias
at run-time depending on how they expect the system to be used.

Subject: [CPUFREQ] Longhaul - Disable arbiter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ACPI C3 works for "Powersaver" processors, so use it only for them.

Older CPU will change frequency on "halt" only. But we can protect transition
in two ways:
- by ACPI PM2 register, there is "bus master arbiter disable" bit.
  This isn't tested because VIA mainboards don't have PM2 register,
- by PLE133 PCI/AGP arbiter disable register.
  There are two bits in this register. First is "PCI arbiter disable",
  second "AGP arbiter disable". This is working on VIA Epia 800 mainboards.

Test on bm_control is more proper because this is true
when PM2 register exist.

Subject: [CPUFREQ] Longhaul - Add ignore_latency option
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some laptops with VIA C3 processor, CLE266 chipset and
AMI BIOS have incorrect latency values in FADT table. These
laptops seems to be C3 capable, but latency values are to
big: 101 for C2 and 1017 for C3. This option will allow
user to skip C3 latency test but not C3 address test. AMI
BIOS is setting C3 address to correct value in DSDT table.

Subject: libata: Separate libata.ko build from individual driver builds

Since some SAS drivers need libata, we can no longer use the rule that
auto-builds libata.ko as needed.  We must instead depend on Kconfig to
determine when to build the library kernel module.

Noticed by Brian King @ IBM.

Subject: [PATCH] zd1211rw: AL2230 ZD1211B vendor sync

This patch synchronizes our code to some recent vendor driver modifications.
A new PHY layout is supported, some values are tweaked, and the AL2230 is now
programmed over a new interface which is many times faster.

Subject: [PATCH] zd1211rw: Support AL7230B RF

This patch adds support for another Airoha RF which is present in some
ZD1211 adapters. This RF supports 802.11a as well as 802.11b/g, but 802.11a
connectivity is not yet supported by this driver.

Subject: [PATCH] zd1211rw: Firmware version vs bootcode version mismatch
 handling

This is needed for my G220F, otherwise it fails to initialize after the
existing firmware upload routine.

The vendor driver actually does more than what I have done here: it
downloads the firmware + boot code, modifies it, and uploads it again
(really messy). I have not copied that part over, as my device can get
on its feet without it.

Subject: [PATCH] zd1211rw: Convert installer CDROM device into WLAN device

Some devices identify themselves as a virtual USB CDROM drive. The virtual CD
includes the windows driver. We aren't interested in this, so we eject the
virtual CDROM and then the real wireless device appears.

Patch fixed over the earlier version to not leak cmd, thanks to Michael Buesch
for spotting that.

Subject: [PATCH] zd1211rw: cleanups

Add static to 2 internal functions. Thanks goes to Adrian Bunk, who found that.

Also made some modifications to the clear functions:

After a discussion on the mailing list, I implemented this code to
have on the one hand sufficient test in debug mode, but on the
other hand reduce the overhead for structure clearing to a
minimum.

A new macro ZD_MEMCLEAR is introduced, which produces code if
DEBUG is set. Locks are not set anymore for structure clearing,
but in debug mode, there is a verification, that the locks have
not been set.

Finally, removed a misleading comment regarding locking in the disconnect
path.

<0>Kernel panic - not syncing: Corrupt kernel stack, can't continue.

This stack overflow occurred during tests on s390 using zfcp.
Recursion depth for this panic was 19.

Usually recursion between blk_run_queue and a request_fn is avoided
using QUEUE_FLAG_REENTER. But this does not help if the scsi stack
tries to flush the starved_list of a scsi_host.

Limit recursion depth when flushing the starved_list
of a scsi_host.

Subject: [SCSI] aacraid: interruptible ioctl

Received from Mark Salyzyn

This patch allows the FSACTL_SEND_LARGE_FIB, FSACTL_SENDFIB and
FSACTL_SEND_RAW_SRB ioctl calls into the aacraid driver to be
interruptible. Only necessary if the adapter and/or the management
software has gone into some sort of misbehavior and the system is being
rebooted, thus permitting the user management software applications to
be killed relatively cleanly. The FIB queue resource is held out of the
free queue until the adapter finally, if ever, completes the command.

Subject: [SCSI] aacraid: Restart adapter on firmware assert (Update 2)

Received from Mark Salyzyn

If the adapter should be in a blinkled (Firmware Assert) state when the
driver loads, we will perform a warm restart of the Adapter Firmware to
see if we can rescue the adapter. Possible causes of a blinkled can
occur on some early release motherboard BIOSes, transitory PCI bus
problems on embedded systems or non-x86 based architectures, transitory
startup failures of early release drives or transitory hardware
failures; some of which can bite the adapter later at runtime. Future
enhancements will include recovery during runtime.

Fixed extra whitespace space issue.

Received from Mark Salyzyn

If the adapter is in blinkled (Firmware Assert) when error recovery
timeout actions have been triggered, perform an adapter warm reset and
restart the initialization.

Subject: [SCSI] Don't add scsi_device for devices that return PQ=1, PDT=0x1f

Some targets may return slight variations of PQ and PDT to indicate
no LUN mapped.  USB UFI setting PDT=0x1f but having reserved bits for
PQ is one example, and NetApp targets returning PQ=1 and PDT=0x1f is
another.  Both instances seem like reasonable responses according to
SPC-3 and UFI specs.

The current scsi_probe_and_add_lun() code adds a scsi_device
for targets that return PQ=1 and PDT=0x1f.  This causes LUNs of type
"UNKNOWN" to show up in /proc/scsi/scsi when no LUNs are mapped.
In addition, subsequent rescans fail to recognize LUNs that may be
added on the target, unless preceded by a write to the delete attribute
of the "UNKNOWN" LUN.

This patch addresses this problem by skipping over the scsi_add_lun()
when PQ=1,PDT=0x1f is encountered, and just returns
SCSI_SCAN_TARGET_PRESENT.

Subject: [SCSI] fc transport: add fc_host system_hostname attribute and
 u64_to_wwn()

This patch updates the fc transport for the following:

- Addition of a new attribute "system_hostname" which can be
  used to set the fully qualified hostname that the fc_host
  is attached to. The fc_host can then register this string
  as the FDMI-based host name attribute.
  Note: for NPIV, a fc_host could be associated with a system which
    is not the local system.

- Add the inline function u64_to_wwn(), which is the inverse of the
  existing wwn_to_u64() function.

- Slight reorg, just to keep dynamic attributes with each other, etc

Subject: [SCSI] BusLogic gcc 4.1 warning fixes

- Reworked all the very long lines in that block (this drivers full of
  them though)

- Returns an error in three places that it didn't before.

- Properly clean up after a scsi_add_host() failure.

Subject: [PATCH] myri10ge: use netif_msg_link

Add msg_enable and use netif_msg_link to enable/disable reporting
of link status changes since some Ethernet switches seem to generate
a lot of status changes under some circumstances and some people
want to avoid useless flooding in the logs.

Also add a counter for link status changes to statistics.

Subject: [PATCH] myri10ge: use multicast support in the firmware

Some recent myri10ge firmwares support multicast filtering as well
as an extended mcp_irq_data structure (64 instead of 40 bytes).
The new command MXGEFW_CMD_SET_STATS_DMA_V2 is used to check
whether the firmware support those. mgp->fw_multicast_support
is defined accordingly.

When fw_multicast_support is set, some new multicast filtering
commands is passed to the board in myri10ge_set_multicast_list().

From cca3974e48607c3775dc73b544a5700b2e37c21a Mon Sep 17 00:00:00 2001
From: Jeff Garzik <jeff@garzik.org>
Date: Thu, 24 Aug 2006 03:19:22 -0400
Subject: libata: Grand renaming.

The biggest change is that ata_host_set is renamed to ata_host.

* ata_host_set			=> ata_host
* ata_probe_ent->host_flags	=> ata_probe_ent->port_flags
* ata_probe_ent->host_set_flags	=> ata_probe_ent->_host_flags
* ata_host_stats		=> ata_port_stats
* ata_port->host		=> ata_port->scsi_host
* ata_port->host_set		=> ata_port->host
* ata_port_info->host_flags	=> ata_port_info->flags
* ata_(.*)host_set(.*)\(\)	=> ata_\1host\2()

The leading underscore in ata_probe_ent->_host_flags is to avoid
reusing ->host_flags for different purpose.  Currently, the only user
of the field is libata-bmdma.c and probe_ent itself is scheduled to be
removed.

ata_port->host is reused for different purpose but this field is used
inside libata core proper and of different type.

Subject: [POWERPC] Rename cpu_setup_power4.S to cpu_setup_ppc970.S

Rename cpu_setup_power4.S to cpu_setup_ppc970.S, since that's
really what it is.

No functional or other changes.

Subject: [POWERPC] Cleanup CPU inits

Cleanup CPU inits a bit more, Geoff Levand already did some earlier.

* Move CPU state save to cpu_setup, since cpu_setup is only ever done
  on cpu 0 on 64-bit and save is never done more than once.
* Rename __restore_cpu_setup to __restore_cpu_ppc970 and add
  function pointers to the cputable to use instead. Powermac always
  has 970 so no need to check there.
* Rename __970_cpu_preinit to __cpu_preinit_ppc970 and check PVR before
  calling it instead of in it, it's too early to use cputable.
* Rename pSeries_secondary_smp_init to generic_secondary_smp_init since
  everyone but powermac and iSeries use it.

Subject: [POWERPC] Add a helper for calculating RTAS "config_addr" parameters

Several RTAS calls take a "config_addr" parameter, which is a particular
way of specifying a PCI busno, devfn and register number into a 32-bit word.
Currently these are open-coded, and I'll be adding another soon, replace
them with a helper that encapsulates the logic. Be more strict about masking
the busno too, just in case.

Booted on P5 LPAR.

Subject: [POWERPC] reboot when panic_timout is set

Only call into RTAS when booted with panic=0 because the RTAS call
does not return.  The system has to be rebooted via the HMC or via the
management console right now.  This is cumbersome and not what the
default panic=180 is supposed to do.

Subject: [SCSI] scsi_transport_sas: remove local_attached flag

This flag denotes local attachment of the phy.  There are two problems
with it:

1) It's actually redundant ... you can get the same information simply
by seeing whether a host is the phys parent
2) we condition a lot of phy parameters on it on the false assumption
that we can only control local phys.  I'm wiring up phy resets in the
aic94xx now, and it will be able to reset non-local phys as well.

I fixed 2) by moving the local check into the reset and stats function
of the mptsas, since that seems to be the only HBA that can't
(currently) control non-local phys.

+SAS Layer
+---------
+
+The SAS Layer is a management infrastructure which manages
+SAS LLDDs.  It sits between SCSI Core and SAS LLDDs.  The
+layout is as follows: while SCSI Core is concerned with
+SAM/SPC issues, and a SAS LLDD+sequencer is concerned with
+phy/OOB/link management, the SAS layer is concerned with:
+
+      * SAS Phy/Port/HA event management (LLDD generates,
+        SAS Layer processes),
+      * SAS Port management (creation/destruction),
+      * SAS Domain discovery and revalidation,
+      * SAS Domain device management,
+      * SCSI Host registration/unregistration,
+      * Device registration with SCSI Core (SAS) or libata
+        (SATA), and
+      * Expander management and exporting expander control
+        to user space.
+
+A SAS LLDD is a PCI device driver.  It is concerned with
+phy/OOB management, and vendor specific tasks and generates
+events to the SAS layer.
+
+The SAS Layer does most SAS tasks as outlined in the SAS 1.1
+spec.
+
+The sas_ha_struct describes the SAS LLDD to the SAS layer.
+Most of it is used by the SAS Layer but a few fields need to
+be initialized by the LLDDs.
+
+After initializing your hardware, from the probe() function
+you call sas_register_ha(). It will register your LLDD with
+the SCSI subsystem, creating a SCSI host and it will
+register your SAS driver with the sysfs SAS tree it creates.
+It will then return.  Then you enable your phys to actually
+start OOB (at which point your driver will start calling the
+notify_* event callbacks).
+
+Structure descriptions:
+
+struct sas_phy --------------------
+Normally this is statically embedded to your driver's
+phy structure:
+	struct my_phy {
+	       blah;
+	       struct sas_phy sas_phy;
+	       bleh;
+	};
+And then all the phys are an array of my_phy in your HA
+struct (shown below).
+
+Then as you go along and initialize your phys you also
+initialize the sas_phy struct, along with your own
+phy structure.
+
+In general, the phys are managed by the LLDD and the ports
+are managed by the SAS layer.  So the phys are initialized
+and updated by the LLDD and the ports are initialized and
+updated by the SAS layer.
+
+There is a scheme where the LLDD can RW certain fields,
+and the SAS layer can only read such ones, and vice versa.
+The idea is to avoid unnecessary locking.
+
+enabled -- must be set (0/1)
+id -- must be set [0,MAX_PHYS)
+class, proto, type, role, oob_mode, linkrate -- must be set
+oob_mode --  you set this when OOB has finished and then notify
+the SAS Layer.
+
+sas_addr -- this normally points to an array holding the sas
+address of the phy, possibly somewhere in your my_phy
+struct.
+
+attached_sas_addr -- set this when you (LLDD) receive an
+IDENTIFY frame or a FIS frame, _before_ notifying the SAS
+layer.  The idea is that sometimes the LLDD may want to fake
+or provide a different SAS address on that phy/port and this
+allows it to do this.  At best you should copy the sas
+address from the IDENTIFY frame or maybe generate a SAS
+address for SATA directly attached devices.  The Discover
+process may later change this.
+
+frame_rcvd -- this is where you copy the IDENTIFY/FIS frame
+when you get it; you lock, copy, set frame_rcvd_size and
+unlock the lock, and then call the event.  It is a pointer
+since there's no way to know your hw frame size _exactly_,
+so you define the actual array in your phy struct and let
+this pointer point to it.  You copy the frame from your
+DMAable memory to that area holding the lock.
+
+sas_prim -- this is where primitives go when they're
+received.  See sas.h. Grab the lock, set the primitive,
+release the lock, notify.
+
+port -- this points to the sas_port if the phy belongs
+to a port -- the LLDD only reads this. It points to the
+sas_port this phy is part of.  Set by the SAS Layer.
+
+ha -- may be set; the SAS layer sets it anyway.
+
+lldd_phy -- you should set this to point to your phy so you
+can find your way around faster when the SAS layer calls one
+of your callbacks and passes you a phy.  If the sas_phy is
+embedded you can also use container_of -- whatever you
+prefer.
+
+
+struct sas_port --------------------
+The LLDD doesn't set any fields of this struct -- it only
+reads them.  They should be self explanatory.
+
+phy_mask is 32 bit, this should be enough for now, as I
+haven't heard of a HA having more than 8 phys.
+
+lldd_port -- I haven't found use for that -- maybe other
+LLDD who wish to have internal port representation can make
+use of this.
+
+
+struct sas_ha_struct --------------------
+It normally is statically declared in your own LLDD
+structure describing your adapter:
+struct my_sas_ha {
+       blah;
+       struct sas_ha_struct sas_ha;
+       struct my_phy phys[MAX_PHYS];
+       struct sas_port sas_ports[MAX_PHYS]; /* (1) */
+       bleh;
+};
+
+(1) If your LLDD doesn't have its own port representation.
+
+What needs to be initialized (sample function given below).
+
+pcidev
+sas_addr -- since the SAS layer doesn't want to mess with
+	 memory allocation, etc, this points to statically
+	 allocated array somewhere (say in your host adapter
+	 structure) and holds the SAS address of the host
+	 adapter as given by you or the manufacturer, etc.
+sas_port
+sas_phy -- an array of pointers to structures. (see
+	note above on sas_addr).
+	These must be set.  See more notes below.
+num_phys -- the number of phys present in the sas_phy array,
+	 and the number of ports present in the sas_port
+	 array.  There can be a maximum num_phys ports (one per
+	 port) so we drop the num_ports, and only use
+	 num_phys.
+
+The event interface:
+
+	/* LLDD calls these to notify the class of an event. */
+	void (*notify_ha_event)(struct sas_ha_struct *, enum ha_event);
+	void (*notify_port_event)(struct sas_phy *, enum port_event);
+	void (*notify_phy_event)(struct sas_phy *, enum phy_event);
+
+When sas_register_ha() returns, those are set and can be
+called by the LLDD to notify the SAS layer of such events
+the SAS layer.
+
+The port notification:
+
+	/* The class calls these to notify the LLDD of an event. */
+	void (*lldd_port_formed)(struct sas_phy *);
+	void (*lldd_port_deformed)(struct sas_phy *);
+
+If the LLDD wants notification when a port has been formed
+or deformed it sets those to a function satisfying the type.
+
+A SAS LLDD should also implement at least one of the Task
+Management Functions (TMFs) described in SAM:
+
+	/* Task Management Functions. Must be called from process context. */
+	int (*lldd_abort_task)(struct sas_task *);
+	int (*lldd_abort_task_set)(struct domain_device *, u8 *lun);
+	int (*lldd_clear_aca)(struct domain_device *, u8 *lun);
+	int (*lldd_clear_task_set)(struct domain_device *, u8 *lun);
+	int (*lldd_I_T_nexus_reset)(struct domain_device *);
+	int (*lldd_lu_reset)(struct domain_device *, u8 *lun);
+	int (*lldd_query_task)(struct sas_task *);
+
+For more information please read SAM from T10.org.
+
+Port and Adapter management:
+
+	/* Port and Adapter management */
+	int (*lldd_clear_nexus_port)(struct sas_port *);
+	int (*lldd_clear_nexus_ha)(struct sas_ha_struct *);
+
+A SAS LLDD should implement at least one of those.
+
+Phy management:
+
+	/* Phy management */
+	int (*lldd_control_phy)(struct sas_phy *, enum phy_func);
+
+lldd_ha -- set this to point to your HA struct. You can also
+use container_of if you embedded it as shown above.
+
+A sample initialization and registration function
+can look like this (called last thing from probe())
+*but* before you enable the phys to do OOB:
+
+static int register_sas_ha(struct my_sas_ha *my_ha)
+{
+	int i;
+	static struct sas_phy   *sas_phys[MAX_PHYS];
+	static struct sas_port  *sas_ports[MAX_PHYS];
+
+	my_ha->sas_ha.sas_addr = &my_ha->sas_addr[0];
+
+	for (i = 0; i < MAX_PHYS; i++) {
+		sas_phys[i] = &my_ha->phys[i].sas_phy;
+		sas_ports[i] = &my_ha->sas_ports[i];
+	}
+
+	my_ha->sas_ha.sas_phy  = sas_phys;
+	my_ha->sas_ha.sas_port = sas_ports;
+	my_ha->sas_ha.num_phys = MAX_PHYS;
+
+	my_ha->sas_ha.lldd_port_formed = my_port_formed;
+
+	my_ha->sas_ha.lldd_dev_found = my_dev_found;
+	my_ha->sas_ha.lldd_dev_gone = my_dev_gone;
+
+	my_ha->sas_ha.lldd_max_execute_num = lldd_max_execute_num; (1)
+
+	my_ha->sas_ha.lldd_queue_size = ha_can_queue;
+	my_ha->sas_ha.lldd_execute_task = my_execute_task;
+
+	my_ha->sas_ha.lldd_abort_task     = my_abort_task;
+	my_ha->sas_ha.lldd_abort_task_set = my_abort_task_set;
+	my_ha->sas_ha.lldd_clear_aca      = my_clear_aca;
+	my_ha->sas_ha.lldd_clear_task_set = my_clear_task_set;
+	my_ha->sas_ha.lldd_I_T_nexus_reset= NULL; (2)
+	my_ha->sas_ha.lldd_lu_reset       = my_lu_reset;
+	my_ha->sas_ha.lldd_query_task     = my_query_task;
+
+	my_ha->sas_ha.lldd_clear_nexus_port = my_clear_nexus_port;
+	my_ha->sas_ha.lldd_clear_nexus_ha = my_clear_nexus_ha;
+
+	my_ha->sas_ha.lldd_control_phy = my_control_phy;
+
+	return sas_register_ha(&my_ha->sas_ha);
+}
+
+(1) This is normally a LLDD parameter, something of the
+lines of a task collector.  What it tells the SAS Layer is
+whether the SAS layer should run in Direct Mode (default:
+value 0 or 1) or Task Collector Mode (value greater than 1).
+
+In Direct Mode, the SAS Layer calls Execute Task as soon as
+it has a command to send to the SDS, _and_ this is a single
+command, i.e. not linked.
+
+Some hardware (e.g. aic94xx) has the capability to DMA more
+than one task at a time (interrupt) from host memory.  Task
+Collector Mode is an optional feature for HAs which support
+this in their hardware.  (Again, it is completely optional
+even if your hardware supports it.)
+
+In Task Collector Mode, the SAS Layer would do _natural_
+coalescing of tasks and at the appropriate moment it would
+call your driver to DMA more than one task in a single HA
+interrupt. DMBS may want to use this by insmod/modprobe
+setting the lldd_max_execute_num to something greater than
+1.
+
+(2) SAS 1.1 does not define I_T Nexus Reset TMF.
+
+Events
+------
+
+Events are _the only way_ a SAS LLDD notifies the SAS layer
+of anything.  There is no other method or way a LLDD to tell
+the SAS layer of anything happening internally or in the SAS
+domain.
+
+Phy events:
+	PHYE_LOSS_OF_SIGNAL, (C)
+	PHYE_OOB_DONE,
+	PHYE_OOB_ERROR,      (C)
+	PHYE_SPINUP_HOLD.
+
+Port events, passed on a _phy_:
+	PORTE_BYTES_DMAED,      (M)
+	PORTE_BROADCAST_RCVD,   (E)
+	PORTE_LINK_RESET_ERR,   (C)
+	PORTE_TIMER_EVENT,      (C)
+	PORTE_HARD_RESET.
+
+Host Adapter event:
+	HAE_RESET
+
+A SAS LLDD should be able to generate
+	- at least one event from group C (choice),
+	- events marked M (mandatory) are mandatory (only one),
+	- events marked E (expander) if it wants the SAS layer
+	  to handle domain revalidation (only one such).
+	- Unmarked events are optional.
+
+Meaning:
+
+HAE_RESET -- when your HA got internal error and was reset.
+
+PORTE_BYTES_DMAED -- on receiving an IDENTIFY/FIS frame
+PORTE_BROADCAST_RCVD -- on receiving a primitive
+PORTE_LINK_RESET_ERR -- timer expired, loss of signal, loss
+of DWS, etc. (*)
+PORTE_TIMER_EVENT -- DWS reset timeout timer expired (*)
+PORTE_HARD_RESET -- Hard Reset primitive received.
+
+PHYE_LOSS_OF_SIGNAL -- the device is gone (*)
+PHYE_OOB_DONE -- OOB went fine and oob_mode is valid
+PHYE_OOB_ERROR -- Error while doing OOB, the device probably
+got disconnected. (*)
+PHYE_SPINUP_HOLD -- SATA is present, COMWAKE not sent.
+
+(*) should set/clear the appropriate fields in the phy,
+    or alternatively call the inlined sas_phy_disconnected()
+    which is just a helper, from their tasklet.
+
+The Execute Command SCSI RPC:
+
+	int (*lldd_execute_task)(struct sas_task *, int num,
+				 unsigned long gfp_flags);
+
+Used to queue a task to the SAS LLDD.  @task is the tasks to
+be executed.  @num should be the number of tasks being
+queued at this function call (they are linked listed via
+task::list), @gfp_mask should be the gfp_mask defining the
+context of the caller.
+
+This function should implement the Execute Command SCSI RPC,
+or if you're sending a SCSI Task as linked commands, you
+should also use this function.
+
+That is, when lldd_execute_task() is called, the command(s)
+go out on the transport *immediately*.  There is *no*
+queuing of any sort and at any level in a SAS LLDD.
+
+The use of task::list is two-fold, one for linked commands,
+the other discussed below.
+
+It is possible to queue up more than one task at a time, by
+initializing the list element of struct sas_task, and
+passing the number of tasks enlisted in this manner in num.
+
+Returns: -SAS_QUEUE_FULL, -ENOMEM, nothing was queued;
+	 0, the task(s) were queued.
+
+If you want to pass num > 1, then either
+A) you're the only caller of this function and keep track
+   of what you've queued to the LLDD, or
+B) you know what you're doing and have a strategy of
+   retrying.
+
+As opposed to queuing one task at a time (function call),
+batch queuing of tasks, by having num > 1, greatly
+simplifies LLDD code, sequencer code, and _hardware design_,
+and has some performance advantages in certain situations
+(DBMS).
+
+The LLDD advertises if it can take more than one command at
+a time at lldd_execute_task(), by setting the
+lldd_max_execute_num parameter (controlled by "collector"
+module parameter in aic94xx SAS LLDD).
+
+You should leave this to the default 1, unless you know what
+you're doing.
+
+This is a function of the LLDD, to which the SAS layer can
+cater to.
+
+int lldd_queue_size
+	The host adapter's queue size.  This is the maximum
+number of commands the lldd can have pending to domain
+devices on behalf of all upper layers submitting through
+lldd_execute_task().
+
+You really want to set this to something (much) larger than
+1.
+
+This _really_ has absolutely nothing to do with queuing.
+There is no queuing in SAS LLDDs.
+
+struct sas_task {
+	dev -- the device this task is destined to
+	list -- must be initialized (INIT_LIST_HEAD)
+	task_proto -- _one_ of enum sas_proto
+	scatter -- pointer to scatter gather list array
+	num_scatter -- number of elements in scatter
+	total_xfer_len -- total number of bytes expected to be transfered
+	data_dir -- PCI_DMA_...
+	task_done -- callback when the task has finished execution
+};
+
+When an external entity, entity other than the LLDD or the
+SAS Layer, wants to work with a struct domain_device, it
+_must_ call kobject_get() when getting a handle on the
+device and kobject_put() when it is done with the device.
+
+This does two things:
+     A) implements proper kfree() for the device;
+     B) increments/decrements the kref for all players:
+     domain_device
+	all domain_device's ... (if past an expander)
+	    port
+		host adapter
+		     pci device
+			 and up the ladder, etc.
+
+DISCOVERY
+---------
+
+The sysfs tree has the following purposes:
+    a) It shows you the physical layout of the SAS domain at
+       the current time, i.e. how the domain looks in the
+       physical world right now.
+    b) Shows some device parameters _at_discovery_time_.
+
+This is a link to the tree(1) program, very useful in
+viewing the SAS domain:
+ftp://mama.indstate.edu/linux/tree/
+I expect user space applications to actually create a
+graphical interface of this.
+
+That is, the sysfs domain tree doesn't show or keep state if
+you e.g., change the meaning of the READY LED MEANING
+setting, but it does show you the current connection status
+of the domain device.
+
+Keeping internal device state changes is responsibility of
+upper layers (Command set drivers) and user space.
+
+When a device or devices are unplugged from the domain, this
+is reflected in the sysfs tree immediately, and the device(s)
+removed from the system.
+
+The structure domain_device describes any device in the SAS
+domain.  It is completely managed by the SAS layer.  A task
+points to a domain device, this is how the SAS LLDD knows
+where to send the task(s) to.  A SAS LLDD only reads the
+contents of the domain_device structure, but it never creates
+or destroys one.
+
+Expander management from User Space
+-----------------------------------
+
+In each expander directory in sysfs, there is a file called
+"smp_portal".  It is a binary sysfs attribute file, which
+implements an SMP portal (Note: this is *NOT* an SMP port),
+to which user space applications can send SMP requests and
+receive SMP responses.
+
+Functionality is deceptively simple:
+
+1. Build the SMP frame you want to send. The format and layout
+   is described in the SAS spec.  Leave the CRC field equal 0.
+open(2)
+2. Open the expander's SMP portal sysfs file in RW mode.
+write(2)
+3. Write the frame you built in 1.
+read(2)
+4. Read the amount of data you expect to receive for the frame you built.
+   If you receive different amount of data you expected to receive,
+   then there was some kind of error.
+close(2)
+All this process is shown in detail in the function do_smp_func()
+and its callers, in the file "expander_conf.c".
+
+The kernel functionality is implemented in the file
+"sas_expander.c".
+
+The program "expander_conf.c" implements this. It takes one
+argument, the sysfs file name of the SMP portal to the
+expander, and gives expander information, including routing
+tables.
+
+The SMP portal gives you complete control of the expander,
+so please be careful.

+ *
+ * Sequencer scratch RAM is 1024 bytes.  This scratch memory is

From 3b4c7d640376dbccfe80fc4f7b8772ecc7de28c5 Mon Sep 17 00:00:00 2001
From: Sukadev Bhattiprolu <sukadev@us.ibm.com>
Date: Mon, 14 Aug 2006 23:12:03 -0700
Subject: [PATCH] kthread: airo.c

The airo driver is currently caching a pid for later use, but with the
implementation of containers, pids themselves do not uniquely identify a
task.  The driver is also using kernel_thread() which is deprecated in
drivers.

This patch essentially replaces the kernel_thread() with kthread_create().
It also stores the task_struct of the airo_thread rather than its pid.
Since this introduces a second task_struct in struct airo_info, the patch
renames airo_info.task to airo_info.list_bss_task.

As an extension of these changes, the patch further:

	 - replaces kill_proc() with kthread_stop()
	 - replaces signal_pending() with kthread_should_stop()
	 - removes thread completion synchronisation which is handled by
	   kthread_stop().

Subject: [PATCH] bcm43xx: >1G and 64bit DMA support

This is a rewrite of the bcm43xx DMA engine. It adds support
for >1G of memory (for chips that support the extension bits)
and 64-bit DMA (for chips that support it).

Subject: [PATCH] bcm43xx: optimization of DMA bitfields

Convert the bitfields in the bcm43xx DMA code to properly
aligned u8 booleans. These flags are accessed in the DMA
hotpath, so it's a good idea to waste a few bytes of memory
for the sake of speed by not requiring masking (and probably
shifting) of the bitfields.

Subject: [PATCH] ieee80211: Fix TKIP and WEP decryption error on SMP machines

The IEEE80211 TKIP and WEP Tx and Rx paths use the same crypto_tfm to encrypt
and decrypt data. During the encrypt and decrypt process, both of them will
set a new key to crypto_tfm. If they happen on the same time, it will
corrupt the crypto_tfm. Thus users will receive an ICV error or Michael MIC
error. This only likely to happen on SMP box with heavy traffic both on Tx
and Rx. The patch use two sets of crypto_tfms to avoid this problem.

Subject: [PATCH] ieee80211: Workaround malformed 802.11 frames from AP

Stop processing further but return success when we receive a malformed
packet from the AP. We need this patch to workaround some AP bugs. For
example, the beacon frames from the Orinoco AP1000 contains an IE (value
= 128) with length equals to 8 but the actual frame length is only 7.

Subject: [PATCH] ipw2200: always enable frequently used debugging code

Moving part of the debugging code from IPW_DEBUG to IPW_LL_DEBUG (low level
debugging) and make IPW_DEBUG be always enabled. IPW_LL_DEBUG still needs
to be enabled by selecting CONFIG_IPW2200_DEBUG. But it is highly
deprecated for normal users since it adds higher debug verbosity in driver
hot paths.

Subject: [PATCH] ipw2200: SIOCGIWFREQ ioctl returns frequency rather than
 channel

The SIOCGIWFREQ ioctl fills the request structure's freq field by setting
the exponent to 0 and the mantissa to the current channel number. The
iwconfig tool works around this behaviour by looking up the frequency
from the channel table if a frequency below 1kHz is returned, other tools
(e.g. kwlaninfo) don't. According to the comment in the iwconfig source
the driver is supposed to return the frequency, not the channel number.

Subject: [PATCH] ipw2200: ipw_wx_set_essid fix

This patch cleanups the ipw_wx_set_essid code and forces a reassociation
when setting the essid to "any". I have tested this patch with iwconfig. It
makes ipw2200 compliant with all the cases mentioned in the iwconfig man
page. The commands

iwconfig iface essid any
iwconfig iface essid -- any
iwconfig iface essid off
iwconfig iface essid on

all seemed to work correctly. None of this worked before the patch.

Note, this patch treats

iwconfig iface essid
iwconfig iface essid ""

The same. It produces an error message: essid: Unknown host.
Since an essid of "" is not mentioned in the iwconfig man page.

Subject: [PATCH] ipw2200: Reassociate even if set the same essid.

This patch traps the case when the essid is being set to its
current value. If the essid is being set again and we are already
associated, chances are some other parameters have also been altered.
I think it is safer to do the re-association for this case.

Subject: [PATCH] ipw2200: remove the MAC timestamp present field from radiotap
 head

IEEE80211_RADIOTAP_TSFT is defined as the Value in microseconds of the
MAC's 64-bit 802.11 Time Synchronization Function timer when the first bit
of the MPDU arrived at the MAC. Since ipw2200 hardware doesn't provide this
value, we disable this feature from the radiotap header present flag.

When command error log debug is enabled, we write every host command and
parameters into a buffer. But we didn't alloc the parameter buffer for this
case. The patch adds struct cmdlog_host_cmd so that the buffer is allocated
from the stack.

Subject: [PATCH] ipw2200: enable wireless extension passive scan

This patch enables the ipw2200 driver to support passive scanning as
offered by the wireless extensions. For this, I enhanced the ipw_wx_set_scan
function in such a way that it differentiates between a passive and an
active scan request. Additionally, I added a new function called
ipw_request_passive_scan that is similiar to the ipw_request_scan
function to perform passive scans. Last but not least, I added a field
(in fact it is a work_struct struct) called request_passive_scan to
the ipw_priv struct.

When bcm43xx-softmac is given an ifdown/ifup sequence, the value for

assert(bcm->mac_suspended>=0) messages. This one-line patch fixes

Subject: [PATCH] sky2: remove cloned/pskb_expand_head check

The code to handle cloned skb overwriting is unnecessary in the
sky2 driver and is buggy. The bug is that pskb_expand_head can change the
skb but the driver has already mapped in the header.

Since the sky2 hardware doesn't need to overwrite memory, the buggy
code can just be removed; it was mistakenly copied from the tg3
driver.

+ *	IDE tuning and bus mastering support for the CS5510/CS5520
+ *	chipsets
+ *
+ *	The CS5510/CS5520 are slightly unusual devices. Unlike the
+ *	typical IDE controllers they do bus mastering with the drive in
+ *	PIO mode and smarter silicon.
+ *
+ *	The practical upshot of this is that we must always tune the
+ *	drive for the right PIO mode. We must also ignore all the blacklists
+ *	and the drive bus mastering DMA information. Also to confuse matters
+ *	further we can do DMA on PIO only drives.
+ *
+ *	DMA on the 5510 also requires we disable_hlt() during DMA on early
+ *	revisions.

+ *
+ *  The ITE8212 isn't exactly a standard IDE controller. It has two
+ *  modes. In pass through mode then it is an IDE controller. In its smart
+ *  mode its actually quite a capable hardware raid controller disguised
+ *  as an IDE controller. Smart mode only understands DMA read/write and
+ *  identify, none of the fancier commands apply. The IT8211 is identical
+ *  in other respects but lacks the raid mode.
+ *
+ *  Errata:
+ *  o	Rev 0x10 also requires master/slave hold the same DMA timings and
+ *	cannot do ATAPI MWDMA.
+ *  o	The identify data for raid volumes lacks CHS info (technically ok)
+ *	but also fails to set the LBA28 and other bits. We fix these in
+ *	the IDE probe quirk code.
+ *  o	If you write LBA48 sized I/O's (ie > 256 sector) in smart mode
+ *	raid then the controller firmware dies
+ *  o	Smart mode without RAID doesn't clear all the necessary identify
+ *	bits to reduce the command set to the one used
+ *
+ *  This has a few impacts on the driver
+ *  - In pass through mode we do all the work you would expect
+ *  - In smart mode the clocking set up is done by the controller generally
+ *    but we must watch the other limits and filter.
+ *  - There are a few extra vendor commands that actually talk to the
+ *    controller but only work PIO with no IRQ.
+ *
+ *  Vendor areas of the identify block in smart mode are used for the
+ *  timing and policy set up. Each HDD in raid mode also has a serial
+ *  block on the disk. The hardware extra commands are get/set chip status,
+ *  rebuild, get rebuild status.
+ *
+ *  In Linux the driver supports pass through mode as if the device was
+ *  just another IDE controller. If the smart mode is running then
+ *  volumes are managed by the controller firmware and each IDE "disk"
+ *  is a raid volume. Even more cute - the controller can do automated
+ *  hotplug and rebuild.
+ *
+ *  The pass through controller itself is a little demented. It has a
+ *  flaw that it has a single set of PIO/MWDMA timings per channel so
+ *  non UDMA devices restrict each others performance. It also has a
+ *  single clock source per channel so mixed UDMA100/133 performance
+ *  isn't perfect and we have to pick a clock. Thankfully none of this
+ *  matters in smart mode. ATAPI DMA is not currently supported.
+ *
+ *  It seems the smart mode is a win for RAID1/RAID10 but otherwise not.
+ *
+ *  TODO
+ *	-	ATAPI and other speed filtering
+ *	-	Command filter in smart mode
+ *	-	RAID configuration ioctls

+ * pata_mpiix.c 	- Intel MPIIX PATA for new ATA layer
+ *			  (C) 2005-2006 Red Hat Inc
+ *			  Alan Cox <alan@redhat.com>
+ *
+ * The MPIIX is different enough to the PIIX4 and friends that we give it
+ * a separate driver. The old ide/pci code handles this by just not tuning
+ * MPIIX at all.
+ *
+ * The MPIIX also differs in another important way from the majority of PIIX
+ * devices. The chip is a bridge (pardon the pun) between the old world of
+ * ISA IDE and PCI IDE. Although the ATA timings are PCI configured the actual
+ * IDE controller is not decoded in PCI space and the chip does not claim to
+ * be IDE class PCI. This requires slightly non-standard probe logic compared
+ * with PCI IDE and also that we do not disable the device when our driver is
+ * unloaded (as it has many other functions).
+ *
+ * The driver conciously keeps this logic internally to avoid pushing quirky
+ * PATA history into the clean libata layer.
+ *
+ * Thinkpad specific note: If you boot an MPIIX using thinkpad with a PCMCIA
+ * hard disk present this driver will not detect it. This is not a bug. In this
+ * configuration the secondary port of the MPIIX is disabled and the addresses
+ * are decoded by the PCMCIA bridge and therefore are for a generic IDE driver
+ * to operate.

+ *	MWDMA is supported.
+ *
+ *	This driver should support Viper-N+, FireStar, FireStar Plus.
+ *
+ *	These devices support virtual DMA for read (aka the CS5520). Later
+ *	chips support UDMA33, but only if the rest of the board logic does,
+ *	so you have to get this right. We don't support the virtual DMA
+ *	but we do handle UDMA.
+ *
+ *	Bits that are worth knowing
+ *		Most control registers are shadowed into I/O registers
+ *		0x1F5 bit 0 tells you if the PCI/VLB clock is 33 or 25Mhz
+ *		Virtual DMA registers *move* between rev 0x02 and rev 0x10
+ *		UDMA requires a 66MHz FSB

+ *
+ *  Documentation
+ *	Most chipset documentation available under NDA only
+ *
+ *  VIA version guide
+ *	VIA VT82C561	-	early design, uses ata_generic currently
+ *	VIA VT82C576	-	MWDMA, 33Mhz
+ *	VIA VT82C586	-	MWDMA, 33Mhz
+ *	VIA VT82C586a	-	Added UDMA to 33Mhz
+ *	VIA VT82C586b	-	UDMA33
+ *	VIA VT82C596a	-	Nonfunctional UDMA66
+ *	VIA VT82C596b	-	Working UDMA66
+ *	VIA VT82C686	-	Nonfunctional UDMA66
+ *	VIA VT82C686a	-	Working UDMA66

+ *	VIA VT8233c	-	UDMA100
+ *	VIA VT8235	-	UDMA133
+ *	VIA VT8237	-	UDMA133
+ *
+ *	Most registers remain compatible across chips. Others start reserved
+ *	and acquire sensible semantics if set to 1 (eg cable detect). A few
+ *	exceptions exist, notably around the FIFO settings.
+ *
+ *	One additional quirk of the VIA design is that like ALi they use few
+ *	PCI IDs for a lot of chips.
+ *
+ *	Based heavily on:
+ *
+ * Version 3.38
+ *
+ * VIA IDE driver for Linux. Supported southbridges:
+ *
+ *   vt82c576, vt82c586, vt82c586a, vt82c586b, vt82c596a, vt82c596b,

Subject: [SCSI] MODULE_FIRMWARE for binary firmware(s)

Right now, various kernel modules are being migrated over to use
request_firmware in order to pull in binary firmware blobs from userland
when the module is loaded. This makes sense.

However, there is right now little mechanism in place to automatically
determine which binary firmware blobs must be included with a kernel in
order to satisfy the prerequisites of these drivers. This affects
vendors, but also regular users to a certain extent too.

The attached patch introduces MODULE_FIRMWARE as a mechanism for
advertising that a particular firmware file is to be loaded - it will
then show up via modinfo and could be used e.g. when packaging a kernel.

Subject: [SCSI] aic94xx: Increase can_queue for better performance

This patch sets can_queue in the aic94xx driver's scsi_host to better
performing values than what's there currently.  It seems that
asd_ha->seq.can_queue reflects the number of requests that can be
queued per controller; so long as there's one scsi_host per
controller, it seems logical that the scsi_host ought to have the same
can_queue value.  To the best of my (still limited) knowledge, this
method provides the correct value.

The effect of leaving this value set to 1 is terrible performance in
the case of either (a) certain Maxtor SAS drives flying solo or (b)
flooding several disks with I/O simultaneously (md-raid).  There may be
more scenarios where we see similar problems that I haven't uncovered.

From 492dfb489658dfe4a755fa29dd0e34e9c8bd8fb8 Mon Sep 17 00:00:00 2001
From: James Bottomley <James.Bottomley@steeleye.com>
Date: Wed, 30 Aug 2006 15:48:45 -0400
Subject: [SCSI] block: add support for shared tag maps

The current block queue implementation already contains most of the
machinery for shared tag maps.  The only remaining pieces are a way to
allocate and destroy a tag map independently of the queues (so that
the maps can be managed on the life cycle of the overseeing entity)

Acked-by: Jens Axboe <axboe@kernel.dk>

Subject: [SCSI] add shared tag map helpers

This patch adds support for sharing tag maps at the host level
(i.e. either every queue [LUN] has its own tag map or there's a single
one for the entire host).  This formulation is primarily intended to
help single issue queue hardware, like the aic7xxx

Subject: 8139cp: sync the device private data with its r8169 counterpart

struct cp_private is reorganized to be more easily compared between the
r8169 and the 8139cp drivers.

The alignment should not be impacted.

Subject: 8139cp: pci_get_drvdata(pdev) can not be NULL in suspend handler

1) pci_set_drvdata() is used in cp_{init/remove}_one to initialize/reset
   driver_data to the relevant value (resp. net_device * and NULL).

2) each of the 3 relevant functions is issued under (device *)->sem:
   2.1) pci_unregister_driver
        -> driver_unregister
           -> bus_remove_driver
              -> driver_detach (takes (device *)->sem)
                 -> __device_release_driver(dev)
                    -> dev->bus-remove(dev) (== pci_device_remove)
                       -> drv->remove(pdev) (== cp_remove_one)
                       [...]
                       pci_dev->driver = NULL;

   2.2) pci_register_driver
        -> __pci_register_driver
           -> driver_register
              -> bus_add_driver
                 -> driver_attach
                    -> __driver_attach (takes (device *)->sem)
                       -> driver_probe_device(drv, dev)
                          -> dev->bus->probe(dev) (== pci_device_probe)
                             -> _pci_device_probe(drv, pci_dev)
                                -> pci_call_probe(drv, pci_dev, id)
                                   -> drv->probe(dev, id) (== cp_init_one)
                                [...]
                                pci_dev->driver = drv;

   2.3) suspend_device (takes (device *)->sem)
        -> dev->bus->suspend(dev) (== pci_device_suspend)
           checking for drv = pci_dev->driver != NULL
           [...]
           -> drv->suspend(pci_dev, state) (== cp_suspend)

dev->sem and the state of pci_dev->driver provide the expected result.

St Mary's day was a bit rainy here.

Subject: e100: fix error recovery

A recent patch in -mm3 titled
"gregkh-pci-pci-don-t-enable-device-if-already-enabled.patch" causes
pci_enable_device() to be a no-op if the kernel thinks that the device is
already enabled.  This change breaks the PCI error recovery mechanism in
the e100 device driver, since, after PCI slot reset, the card is no longer
enabled.  This is a trivial fix for this problem.  Tested.

Subject: [SCSI] sd: fix cache flushing on module removal (and individual
 device removal)

The fix isn't actually in sd: it's in scsi_device_get().  I modified it
to allow devices to be returned in SDEV_CANCEL, but not SDEV_DEL.  This
means that the device_remove_driver, which occurs in device_del() in
scsi_remove_device() after the device has gone into SDEV_CANCEL is now
effective at flushing the cache.

Subject: [SCSI] SCSI: sanitize INQUIRY strings

Sanitize the Vendor, Product, and Revision strings contained in an
INQUIRY result by setting all non-graphic or non-ASCII characters to ' '.
Since the standard disallows such characters, this will affect
only non-compliant devices.

To help maintain backward compatibility, NUL characters are treated
specially.  They are taken as string terminators; they and all the
following characters are set to ' '.  If some valid characters get
erased as a result... well, we weren't seeing them before so we haven't
lost anything.

The primary purpose of this change is to allow blacklist entries to
match devices with illegal Vendor or Product strings.

In addition, the patch updates a couple of function prototypes, giving
inq_result its correct type (unsigned char *).

Subject: [SCSI] libiscsi, iscsi_tcp, iscsi_iser: check that burst lengths are
 valid.

iSCSI RFC states that the first burst length must be smaller than the
max burst length. We currently assume targets will be good, but that may
not be the case, so this patch adds a check.

This patch also moves the unsol data out offset to the lib so the LLDs
do not have to track it.

Subject: [SCSI] add refcouting around ctask usage in main IO patch

It is possible that a ctask could be completing and getting
cleaned up at the same time, we are finishing up the last
data transfer. This could then result in the data transfer
code using stale or invalid values. This patch adds a refcount
to the ctask. When the count goes to zero then we know the
transmit thread and recv thread or softirq are not touching
it and we can safely release it.

The eh should not need to grab a reference because it only cleans
up a task if it has both the xmit mutex and recv lock (or recv
side suspended).

Subject: [SCSI] attempt to complete r2t with data len greater than max burst

A couple targets like string bean and MDS, send r2ts with
a data len greater than the max burst we agreed to. We
were being strict in our enforcing of the iscsi rfc in that
code path, but there is no driver limitation that prevents
us from fullfilling the request. To allow those targets
to work we will ignore the max_burst length and send as
much data as the target asks for assuming it has consciously
decided to override its max burst length.

Subject: [SCSI] iscsi_tcp: fix padding, data digests, and IO at weird offsets

iscsi_tcp calculates padding by using the expected transfer length. This
has the problem where if we have immediate data = no and initial R2T =
yes, and the transfer length ended up needing padding then we send:

1. header
2. padding which should have gone after data
3. data

Besides this bug, we also assume the target will always ask for nice
transfer lengths and the first burst length will always be a nice value.
As far as I can tell form the RFC this is not a requirement. It would be
silly to do this, but if someone did it we will end doing bad things.

Finally the last bug in that bit of code is in our handling of the
recalculation of data digests when we do not send a whole iscsi_buf in
one try. The bug here is that we call crypto_digest_final on a
iscsi_sendpage error, then when we send the rest of the iscsi_buf, we
doiscsi_data_digest_init and this causes the previous data digest to be
lost.

And to make matters worse, some of these bugs are replicated over and
over and over again for immediate data, solicited data and unsolicited
data. So the attached patch made over the iscsi git tree (see
kernel.org/git for details) which I updated today to include the patches
I said I merged, consolidates the sending of data, padding and digests
and calculation of data digests and fixes the above bugs.

Subject: [SCSI] scsi_tcp: rm data rx and tx tfms

We currently allocated seperate tfms for data and header digests. There
is no reason for this since we can never calculate a rx header and
digest at the same time. Same for sends. So this patch removes the data
tfms and has the send and recv sides use the rx_tfm or tx_tfm.

I also made the connection creation code preallocate the tfms because I
thought I hit a bug where I changed the digests settings during a
relogin but could not allocate the tfm and then we just failed.

Subject: [SCSI] iscsi_tcp: fix header resend

This patch built over the last ones fixes a bug in the partial header
resend code, where we add on another 4 bytes to the send length on the resend.
We want just the header plus digest.

When a digest is spread across two network buffers, we currently
ignore this and try to check the digest with the partial buffer.
Or course this fails. This patch has use iscsi_tcp_copy to
copy the whole digest before testing it.

If the scsi eh sends a TUR and the session is down we could
return SCSI_ML_HOST_BUSY. scsi eh will ignore this and send
ask us to abort the command and we blindly accesst the
command ptr.

Subject: [SCSI] libiscsi: don't call into lld to cleanup task

In the normal IO path we should not be calling back
into the LLD since the LLD will have cleaned up the
task before or after calling complete pdu.

For the fail_command path we still need to do this
to force the cleanup.

When accessing a device with disabled read access the capacity is set
randomly to 1GB. This makes it impossible to userspace tools to detect
invalid device capacities.

Subject: [SCSI] Add Promise SuperTrak driver

Add Promise SuperTrak 'stex' driver, supporting SuperTrak
EX8350/8300/16350/16300 controllers.  The controller's firmware accepts
SCSI commands, handing them to the underlying RAID or JBOD disks.

The driver consisted of the following cleanups and fixes, beyond its
initial submission:

Ed Lin:
      stex: cleanup and minor fixes
      stex: add new device ids
      stex: update internal copy code path
      stex: add hard reset function
      stex: adjust command timeout in slave_config routine
      stex: use more efficient method for unload/shutdown flush

Jeff Garzik:
      [SCSI] Add Promise SuperTrak 'shasta' driver.
      Rename drivers/scsi/shasta.c to stex.c ("SuperTrak EX").
      [SCSI] stex: update with community comments from 'Promise SuperTrak' thread
      [SCSI] stex: Fix warning, trim trailing whitespace.
      [SCSI] stex: remove last remnants of "shasta" project code name
      [SCSI] stex: removed 6-byte command emulation
      [SCSI] stex: minor cleanups
      [SCSI] stex: minor fixes: irq flag, error return value
      [SCSI] stex: use dma_alloc_coherent()

From cf355883f506051a8ce3ac4539752829320b6c8c Mon Sep 17 00:00:00 2001
From: Ed Lin <ed.lin@promise.com>
Date: Fri, 1 Sep 2006 14:31:51 +0800
Subject: [SCSI] stex: add shared tags from block

Use block shared tags entirely within the driver. In the case of
shutdown, assume that there are no other outstanding commands, so tag
0 is fine.

Subject: [SCSI] SCSI and FC Transport: add netlink support for posting of
 transport events

This patch formally adds support for the posting of FC events via netlink.
It is a followup to the original RFC at:
  http://marc.theaimsgroup.com/?l=linux-scsi&m=114530667923464&w=2
and the initial posting at:
  http://marc.theaimsgroup.com/?l=linux-scsi&m=115507374832500&w=2

The patch has been updated to optimize the send path, per the discussions
in the initial posting.

Per discussions at the Storage Summit and at OLS, we are to use netlink for
async events from transports. Also per discussions, to avoid a netlink
protocol per transport, I've create a single NETLINK_SCSITRANSPORT protocol,
which can then be used by all transports.

This patch:
- Creates new files scsi_netlink.c and scsi_netlink.h, which contains the
  single and shared definitions for the SCSI Transport. It is tied into the
  base SCSI subsystem intialization.
  Contains a single interface routine, scsi_send_transport_event(), for a
  transport to send an event (via multicast to a protocol specific group).
- Creates a new scsi_netlink_fc.h file, which contains the FC netlink event
  messages
- Adds 3 new routines to the fc transport:
   fc_get_event_number() -  to get a FC event #
   fc_host_post_event()  -  to send a simple FC event (32 bits of data)
   fc_host_post_vendor_event() - to send a Vendor unique event, with
                                 arbitrary amounts of data.

   Note: the separation of event number allows for a LLD to send a standard
     event, followed by vendor-specific data for the event.

Note: This patch assumes 2 prior fc transport patches have been installed:
   http://marc.theaimsgroup.com/?l=linux-scsi&m=115555807316329&w=2
   http://marc.theaimsgroup.com/?l=linux-scsi&m=115581614930261&w=2

   Sorry - next time I'll do something like making these individual
   patches of the same posting when I know they'll be posted closely
   together.

Subject: [SCSI] SCSI & FC transport: extend event vendor id's to 64bits

During discussions with Mike Christie, I became convinced that we needed
a larger vendor id. This patch extends the id from 32 to 64 bits.

This applies on top of the prior patches that add SCSI transport events
via netlink.

Subject: [SCSI] FC transport: Add dev_loss_tmo callbacks, and new
 fast_io_fail_tmo w/ callback

This patch adds the following functionality to the FC transport:

- dev_loss_tmo LLDD callback :
  Called to essentially confirm the deletion of an rport. Thus, it is
  called whenever the dev_loss_tmo fires, or when the rport is deleted
  due to other circumstances (module unload, etc).  It is expected that
  the callback will initiate the termination of any outstanding i/o on
  the rport.

- fast_io_fail_tmo and LLD callback:
  There are some cases where it may take a long while to truly determine
  device loss, but the system is in a multipathing configuration that if
  the i/o was failed quickly (faster than dev_loss_tmo), it could be
  redirected to a different path and completed sooner.

Many thanks to Mike Reed who cleaned up the initial RFC in support
of this post.

The original RFC is at:

From c01f32087960edd60a302ad62ad6b8b525e4aeec Mon Sep 17 00:00:00 2001
From: James Smart <James.Smart@Emulex.Com>
Date: Fri, 18 Aug 2006 17:47:08 -0400
Subject: [SCSI] lpfc 8.1.10 : Add support for dev_loss_tmo_callbk and
 fast_io_fail_tmo_callbk

Add support for new dev_loss_tmo callback
  Goodness is that it removes code for a parallel nodev timer that
  existed in the driver
Add support for the new fast_io_fail callback

Subject: [CPUFREQ] Longhaul - Add voltage scaling to driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rename option "dont_scale_voltage" to "scale_voltage" because
don't will be default.
Use "pos" for calculating voltage. In this way driver don't need
to know mV value or low level value. Simply min U is one pos and
max U is second pos. All pos between these two are used.
Assume that min U is for min f and max U for max f. For frequency
between min and max calculate pos based on difference between
current frequency and min f.
Values in mobile VRM table changed to values from
C3-M datasheet.

Subject: [CPUFREQ] Workaround for BIOS bug in software coordination of
 frequency

Some buggy BIOSes do a "software any" kind of coordination without telling
about it to OS. So, when OS sets frequency on one CPU on these platforms,
it will also impact all the other logical CPUs that are in the same power
domain. Attached patch is a workaround for those buggy BIOSes.
Patch should be a noop on the normal non-buggy platforms.

Applies over previously sent acpi-cpufreq and software coordination
bug fix patch

Subject: [PATCH] forcedeth: decouple vlan and rx checksum dependency

This patch decouples the dependency between the rx checksum feature and
vlan feature. This is done by ignoring the checksum information if the
user has disabled rx checksum when vlan is enabled.

Subject: [PATCH] myri10ge: improve firmware selection

Improve the firmware selection by adding 2 cases where we should use the
optimized firmware:
* when the actual PCIe link width is lower than 8x.
* when the board is plugged to one of the new Intel PCIe chipsets that
  are known to provide aligned PCIe completions.

The patch actually raises two concerns:
* We might want to add a generic PCI function to get the PCIe link width since
  some other drivers (at least ipath) do the same. But we probably do not want
  to add a new function for every PCIe capability. I will probably look at it
  and discuss it on linux-pci in the future.
* As requested during the submission, the PCI ids of chipsets that are known to
  provided aligned completion are defined in the myri10ge code. If we keep adding
  new ones, it might become better to move them to pciids.h.
  But, this sort of quirk to detect these chipsets are very specific to our NIC,
  I don't think it is worth moving it to the PCI core until somebody else really
  needs it.

Subject: [SCSI] Fix refcount breakage with 'echo "1" > scan' when target
 already present

Spotted by: Dan Aloni <da-xx@monatomic.org>

The problem is there's inconsistent locking semantic usage of
scsi_alloc_target().  Two callers assume the target comes back with
reference unincremented and the third assumes its incremented.  Fix by
always making the reference incremented on return.  Also fix path in
target alloc that could consistently increment the parent lock.
Finally document scsi_alloc_target() so its callers know what the
expectations are.

Subject: [SCSI] fix up non-modular SCSI

The recent change to the way scsi_device_get()/put() work broke the
non modular build (we do a module_refcount on a NULL).  Fix this by
checking for non-null before checking module_refcount().

Subject: [SCSI] SAS: consolidate linkspeed definitions

At the moment we have two separate linkspeed enumerations covering
roughly the same values.  This patch consolidates on a single one enum
sas_linkspeed in scsi_transport_sas.h and uses it everywhere in the
aic94xx driver.  Eventually I'll get around to removing the duplicated
fields in asd_sas_phy and sas_phy ...

Subject: [SCSI] scsi_transport_sas: make minimum and maximum linkrate settable
 quantities

According to SPEC, the minimum_linkrate and maximum_linkrate should be
settable by the user.  This patch introduces a callback that allows the
sas class to pass these settings on to the driver.

Subject: [SCSI] aci94xx: implement link rate setting

This patch implements the ability to set the minimum and maximum
linkrates for both libsas (for expanders) and aic94xx (for the host
phys).  It also tidies up the setting of the hardware min and max to
make sure they're updated when the expander emits a change broadcast.

Subject: [AGPGART] Rework AGPv3 modesetting fallback.

Sometimes the logic to handle AGPx8->AGPx4 fallback failed, as can
be seen in https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=197346

The failures occured if the bridge was in AGPx8 mode, but the
user hadn't specified a mode in their X config.  We weren't
setting the mode to the highest mode capable by the video card+bridge
(as we do in the AGPv2 case), which was leading to all kinds of
mayhem including us believing that after falling back from AGPx8, that
we couldn't do x4 mode (which is disastrous in AGPv3, as those are
the only two modes possible).

Subject: [PATCH] cleanup unnecessary forcedeth printk

This removes unnecessary messages that show up every time I put my
ethernet card in promiscuous mode.  I'm already getting notification
from the networking layer, I don't need notification from the driver as
well.

There are probably other drivers that do this as well -- I'll look
around and see what I can find.

Subject: r8169: quirk for the 8110sb on arm platform

Inverting the write ordering of the TxDescAddr{High/Low} registers
suffices to trigger a sabbat of PCI errors which make the device
completely dysfunctional. The issue has not been reported on a
different platform.

Switching from MMIO accesses to I/O ones as done in Realtek's
own driver fixes (papers over ?) the bug as well but I am not
thrilled to see everyone pay the I/O price for an obscure bug.

This is the minimal change to handle the issue.

Subject: [PATCH] zd1211rw: Removed unneeded packed attributes

Inspired by an e-mail by Stephen Hemminger I decided to remove all
unneeded packed attributes from the code where the member variables are
already aligned. This avoids horrible code being generated on some
architectures.

This patch prints microcode revision, patchlevel, date and time to
KERN_INFO. Also, version 4.xx microcodes (rev>0x128) will be rejected
by the driver, because they still do not work.

There are only two users of module_refcount() outside of kernel/module.c
and the other one uses ifdef's similar to this.

Subject: [PATCH] Remove more unnecessary driver printk's

As I promised last week, here is the first pass at removing all
unnecessary printk's that exist in network device drivers currently in
promiscuous mode.  The duplicate messages are not needed so they have
been removed.  Some of these drivers are quite old and might not need an
update, but I did them all anyway.

I am currently auditing the remaining conditional printk's and will send
out a patch for those soon.

Subject: 8139cp: ring_info removal for the transmit path

As long as the descriptor fits on a single cacheline, the change
should be almost free.

Now ring_info is not used at all. Remove it.

Subject: [PATCH] e1000: revert 'e1000: Remove 0x1000 as supported device'

The commit 'e1000: Remove 0x1000 as supported device' (Jeff Kirsher,
673a052fde79ab5e9dce569b0336358812ddba2d) Removes PIC device ID 8086:1000
from the list of supported devices. A fix was submitted for the original
issue (commit 6a9516989f94df10d9a27ba543c6b53b3e69c84a).

This commit reverts commit 673a052fde79ab5e9dce569b0336358812ddba2d and
re-enables 82542rev3 chips completely.

Subject: [POWERPC] Split out vpa unregister logic from
 pseries_kexec_cpu_down_xics()

As part of the new irq code pseries_kexec_cpu_down() was split into a
xics and mpic version. The vpa unregister logic is now only done in the
xics routine, and although that's ok in practice (we don't have SPLPAR
machines with mpic), I'd rather have the two concepts stay separate.

So move the vpa unregister into pseries_kexec_cpu_down(), which gets called
by both the xics and mpic routines. This also gives us an obvious place to
put any new kexec-down logic needed in future.

Subject: [POWERPC] Make function of pm_power_off consistent with x86

Allow the pm_power_off function variable in PPC to work as an override.
This makes the function consistent with the other architectures and it
allows generic poweroff operations (like those provided in IPMI
systems) to work properly on PPC.

The following patch allows XMON to run on the 4xx platform.  Tested on
Walnut, Ebony, and Nova (440GX based) eval boards.  440EP, 440SP, and
440SPE boards should work as well.  Patch is against 2.6.18-rc6.

Subject: [POWERPC] powerpc: Reduce default cacheline size to 64 bytes

Reduce default cacheline size on 64-bit powerpc from 128 bytes to 64.
This is the architected minimum. In most cases we'll still end up using
cache line information from the device tree, but defaults are used during
early boot and doing a few dcbst/icbi's too many there won't do any harm.

Subject: [POWERPC] powerpc: Divorce CPU_FTR_CTRL from
 CPU_FTR_PPCAS_ARCH_V2_BASE

The performance monitor implementation (including CTRL register behaviour)
is just included in PPC v2 as an example, it's not truly part of the base.

It's actually a somewhat misleading feature, but I'll leave that be for
now: The presence of the register is not what the feature bit is used
for, but instead it's used to determine if it contains the runlatch
bit for idle reporting of the performance monitor. For alternative
implementations, the register might still exist but the bit might have
different meaning (or no meaning at all).

For now, split it off and don't include it in CPU_FTR_PPCAS_ARCH_V2_BASE.

Subject: [POWERPC] powerpc: PA Semi PWRficient platform support

Base patch for PA6T and PA6T-1682M. This introduces the
arch/powerpc/platform/pasemi directory, together with basic
implementations for various setup.

Much of this was based on other platform code, i.e. Maple, etc.

Subject: [POWERPC] powerpc: Instrument Hypervisor Calls

Add instrumentation for hypervisor calls on pseries.  Call statistics
include number of calls, wall time and cpu cycles (if available) and
are made available via debugfs.  Instrumentation code is behind the
HCALL_STATS config option and has no impact if not enabled.

Subject: [POWERPC] Quiet hvc_console console output on failed opens

No other tty driver will print on the console when the open of it fails.

On systems that happen to be configured for both ttyS0 and hvc0 console,
this will keep flooding the console output.  This is most likely to
happen with systems booted between with and without hypervisor from the
same filesystem.

Let's just remove it. When it's really needed (i.e. when the open fails
and someone is trying to debug it), noone will see the output anyway. And
init will report the opens failing in due time through the syslog.

From 7de745e56244156233e5cdd62b462e52e638d408 Mon Sep 17 00:00:00 2001
From: Don Fry <brazilnut@us.ibm.com>
Date: Wed, 13 Sep 2006 10:16:53 -0700
Subject: [PATCH] pcnet32: NAPI implementation

Implement NAPI changes to pcnet32 driver.  Compile default is off.
Listed as experimental.

Len and Don both worked on a NAPI implementation and have both tested
these changes.

An e1000 blasting short packets to the pcnet32 will lockup Don's system
until the receive storm stops.  Without NAPI Len's system watchdog would
expire causing the system to reboot.  With NAPI the system will stay
operational.

Tested ia32 and ppc64.  Tested '970A, '971, '972, '973, '975, '976, and
'978.

The Kconfig changes came from Len.  Don is to blame for all the others.

Hi Jeff,

I fixed the __iomem issue and tested the driver with sparse. Looks good so far.
Thanks for your effort.

 /* Command style register access
 
-Registers CMD0, CMD2, CMD3,CMD7 and INTEN0 uses a write access technique called command style access. It allows the write to selected bits of this register without altering the bits that are not selected. Command style registers are divided into 4 bytes that can be written independently. Higher order bit of each byte is the  value bit that specifies the value that will be written into the selected bits of register. 
+Registers CMD0, CMD2, CMD3,CMD7 and INTEN0 uses a write access technique called command style access. It allows the write to selected bits of this register without altering the bits that are not selected. Command style registers are divided into 4 bytes that can be written independently. Higher order bit of each byte is the  value bit that specifies the value that will be written into the selected bits of register.
 
 eg., if the value 10011010b is written into the least significant byte of a command style register, bits 1,3 and 4 of the register will be set to 1, and the other bits will not be altered. If the value 00011010b is written into the same byte, bits 1,3 and 4 will be cleared to 0 and the other bits will not be altered.

From 2eaba1a280b6380f5b1238c53ce62e4381fc5f97 Mon Sep 17 00:00:00 2001
From: Stephen Hemminger <shemminger@osdl.org>
Date: Wed, 6 Sep 2006 12:44:47 -0700
Subject: [PATCH] sky2: tx pause bug fix

Fix problems with transmit pause frames. The driver was telling the
GMAC to flush (not process) pause frames. Manually disabling pause wasn't
working because of problems in the setup.

This maybe the cause of the lockup under load.

Subject: [POWERPC] Fix non-smp build

This fixes a compile error that only surfaces on CONFIG_SMP=n builds;
<asm/hvcall.h> seems to get pulled in through another header file for
SMP builds.  This problem was introduced by the hvcall stats patch.

Subject: [PATCH] e1000 disable device on PCI error

A recent patch in -mm3 titled
"gregkh-pci-pci-don-t-enable-device-if-already-enabled.patch" causes
pci_enable_device() to be a no-op if the kernel thinks that the device is
already enabled.  This change breaks the PCI error recovery mechanism in
the e1000 device driver, since, after PCI slot reset, the card is no longer
enabled.  This is a trivial fix for this problem.  Tested.

Subject: [PATCH] ehea: bugfix for register access functions

Hi Jeff,

sorry to bother you again. We figured out that the readq function we
included in the eHEA patch we sent yesterday to access eHEA registers
is defined as little endian on POWER. This collides with our adapter.
We talked to some PPC people who told us there is a discussion going
on about new access functions. We were told to use __raw_readq /
__raw_writeq for now.

This patch fixes this bug found by our internal tests today.
Please apply this small patch on the latest patch we sent you yesterday.
If it is easier for you I can also give you the entire eHEA patch again.

sorry and thanks a lot,
Jan-Bernd

Subject: Fix libata resource conflict for legacy mode

When the libata is trying to handle legacy ide ports (0x1f0 for instance), it
doesn't take care if the resource has childs or not.
The result is that this situation :
0100-01fe : pnp 00:09
  0170-0177 : libata
  01f0-01f7 : libata

is seen as conflict, which is wrong.
The proposed fix is to detect childs and in this case, look at which child is
conflicting.

Subject: [PATCH] libata: fix non-uniform ports handling

Non-uniform ports handling got broken while updating libata to handle
those in the same host.  Only separate irq for the non-uniform
secondary port was implemented while all other fields (host flags,
transfer mode...) of the secondary port simply shared those of the
first.

For ata_piix combined mode, which ATM is the only user of non-uniform
ports, this causes the secondary port assume the wrong type.  This can
cause PATA port to use SATA ops, which results in bogus check on PCS
and detection failure.

This patch adds ata_probe_ent->pinfo2 which points to optional
port_info for the secondary port.  For the time being, this seems to
be the simplest solution.  This workaround will be removed together
with ata_probe_ent itself after init model is updated to allow more
flexibility.

Subject: [PATCH] libata: improve handling of diagostic fail (and hardware that
 misreports it)

Our ATA probe code checks that a device is not reporting a diagnostic
failure during start up. Unfortunately at least one device seems to like
doing this - the Gigabyte iRAM.

This is only done for the master right now (which is fine for the iRAM
as it is SATA), as with PATA some combinations of ATAPI device seem to
fool the check into seeing a drive that isn't there if it is applied to
the slave.

The io accessors insw_ns, outsw_ns, insl_ns and outsl_ns are unused
(except for one unnecessary use in drivers/net/3c509.c that is addressed
in a previous patch) and are only defined in powerpc/ppc, so remove them.

From 5adcaf50cf697aa4d0c731107003c1383b59b214 Mon Sep 17 00:00:00 2001
From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Tue, 19 Sep 2006 22:17:49 +1000
Subject: [POWERPC] convert string i/o operations to C

This produces essentially the same code and will make the iSeries i/o
consolidation easier.

The count parameter is changed to long since that will produce the same
(better) code on 32 and 64 bit builds.

Subject: [POWERPC] Define of_read_ulong helper

There are various places where we want to extract an unsigned long
value from a device-tree property that can be 1 or 2 cells in length.
This replaces some open-coded calculations, and one place where we
assumed without checking that properties were the length we wanted,
with a little of_read_ulong() helper.

Subject: [POWERPC] Start arch/powerpc/boot code reorganization

This abstracts the operations used in the bootwrapper, and defines
the operations needed for the bootwrapper to run on an OF platform.

The operations have been divided up into platform ops (platform_ops),
firmware ops (fw_ops), device tree ops (dt_ops), and console ops
(console_ops).

The proper operations will be hooked up at runtime to provide the
functionality that you need.

From 1534c3820c26aca4e2567f97b8add8bea40e7e2b Mon Sep 17 00:00:00 2001
From: Martin Schwidefsky <schwidefsky@de.ibm.com>
Date: Wed, 20 Sep 2006 15:58:25 +0200
Subject: [S390] zcrypt adjunct processor bus.

Add a bus for the adjunct processor interface. Up to 64 devices can
be connect to the ap bus interface, each device with 16 domains. That
makes 1024 message queues. The interface is asynchronous, the answer
to a message sent to a queue needs to be received at some later point
in time. Unfortunately the interface does not provide interrupts when
a message reply is pending. So the ap bus needs to implement some
fancy polling, each active queue is polled once per 1/HZ second or
continuously if an idle cpus exsists and the poll thread is activ
(see poll_thread parameter).

The ap bus uses the sysfs path /sys/bus/ap and has two bus attributes,
ap_domain and config_time. The ap_domain selects one of the 16 domains
to be used for this system. This limits the maximum number of ap devices
to 64. The config_time attribute contains the number of seconds between
two ap bus scans to find new devices.

The ap bus uses the modalias entries of the form "ap:tN" to autoload
the ap driver for hardware type N. Currently known types are:

Subject: [S390] zcrypt user space interface.

The user space interface of the zcrypt device driver implements the old
user space interface as defined by the old z90crypt driver. Everything
is there, the /dev/z90crypt misc character device, all the lovely ioctls
and the /proc file. Even writing to the z90crypt proc file to configure
the crypto device still works. It stands to reason to remove the proc
write function someday since a much cleaner configuration via the sysfs
is now available.

The ap bus device drivers register crypto cards to the zcrypt user
space interface. The request router of the user space interface
picks one of the registered cards based on the predicted latency
for the request and calls the driver via a callback found in the
zcrypt_ops of the device. The request router only knows which
operations the card can do and the minimum / maximum number of bits
a request can have.

Subject: [S390] zcrypt driver Makefile, Kconfig and monolithic build.

The Makefile and Kconfig changes should be obvious. The monolithic
build option is there to create an old-style z90crypt module for
backward compatability to older distributions.

Subject: [S390] zcrypt secure key cryptography extension.

Allow the user space to send extended cprb messages directly to the
PCIXCC / CEX2C cards. This allows the CCA library to construct special
crypto requests that use "secure" keys that are stored on the card.

From 65912a84c0f33304fa5ea004c7b6ee58d5f5572e Mon Sep 17 00:00:00 2001
From: Heiko Carstens <heiko.carstens@de.ibm.com>
Date: Wed, 20 Sep 2006 15:58:41 +0200
Subject: [S390] initrd vs. bootmem bitmap.

Move initrd if the bitmap of the bootmem allocator would overwrite it.
In addition this patch sets the default size and address of the initrd to 0.
Therefore all boot loaders must set the initrd size and address correctly.
This is especially relevant for ftp boot via HMC/SE, where this change
requires a special patch file entry in the .ins file which sets these two
values contained at address 0x10408 and 0x10410.

From ff6b8ea68f4b7353f88b97024f28127e2148aa00 Mon Sep 17 00:00:00 2001
From: Michael Holzheu <holzheu@de.ibm.com>
Date: Wed, 20 Sep 2006 15:58:49 +0200
Subject: [S390] ipl/dump on panic.

It is now possible to specify a ccw/fcp dump device which is used to
automatically create a system dump in case of a kernel panic. The dump
device can be configured under /sys/firmware/dump.
In addition it is now possible to specify a ccw/fcp device which is used
for the next reboot of Linux. The reipl device can be configured under
/sys/firmware/reipl.

Subject: [S390] fix syscall restart handling.

If do_signal() gets called several times before returning to user space
and no signal is pending (e.g. cancelled by a debugger) syscall restart
handling could be done several times. This would change the user space
PSW to an address prior to the syscall instruction.
Fix this by making sure that syscall restart handling is only done once.

Subject: [S390] Use simple_strtoul instead of own cmm_strtoul wrapper.

Fix compile warning with some configurations:

arch/s390/mm/cmm.c:58: warning: 'cmm_strtoul' defined but not used

Originally cmm_strtoul was introduced because simple_strtoul couldn't
handle strings with hexadecimal numbers that contained a capital 'X'.
Since this is no longer true cmm_strtoul can be removed.

qdio_get_micros is supposed to return microseconds. The get_clock()

Subject: [S390] dasd deadlock after state change pending interrupt.

The dasd_device_from_cdev function is called from interrupt context
to get the struct dasd_device associated with a ccw device. The
driver_data of the ccw device points to the dasd_devmap structure
which contains the pointer to the dasd_device structure. The lock
that protects the dasd_devmap structure is acquire with out irqsave.
To prevent the deadlock in dasd_device_from_cdev if it is called
from interrupt context the dependency to the dasd_devmap structure
needs to be removed. Let the driver_data of the ccw device point
to the dasd_device structure directly and use the ccw device lock
to protect the access.

Subject: [S390] cleanup sysinfo and add system z9 specific extensions.

With System z9 additional fields have been added to the output of the
store system information instruction. This patch adds the new model
information field and the alternate cpu capability fields to the
output of /proc/sysinfo. While we at it clean up the code as well.

Subject: [S390] Missing initialization in common i/o layer.

Previous patch that was intended to reduce stack usage within common
i/o layer didn't consider implicit memset(..., 0, ...) used with the
initializations used before.
Add these missing memsets wherever it's not obvious that the
concerned memory region is zeroed. This should give the same semantics
as before.

Subject: [S390] cio: subchannels in no-path state.

Subchannel may incorrectly remain in state no-path after channel paths
have reappeared. Currently the scan for subchannels which are using a
channel path ends at the first occurrence if a full link address was
provided by the channel subsystem. The scan needs to continue over
all subchannels.

CHPIDs that are logically varied off will not be removed from
a CCW device's path group because resign-from-pathgroup command is
issued with invalid path mask of 0 because internal CCW operations
are masked by the logical path mask after the relevant bits are
cleared by the vary operation.
Do not apply logical path mask to internal operations.

Subject: [S390] cio: always query all paths on path verification.

Reappearing channel paths are sometimes not utilized by CCW devices
because path verification incorrectly relies on path-operational-mask
information which is not updated until a channel path has been used
again.
Modify path verification procedure to always query all available paths
to a device.

Subject: [S390] cio: subchannel evaluation function operates without lock

css_evaluate_subchannel() operates subchannel without lock which can
lead to erratic behavior caused by concurrent device access. Also
split evaluation function to make it more readable.

Subject: [S390] hypfs crashes with invalid mount option.

When an invalid mount option is specified, no root inode is created
for hypfs, hypfs_fill_super() returns with -EINVAL and then
hypfs_kill_super() is called. hypfs_kill_super() does not check if
the root inode has been initialized. This patch adds this check.

Subject: configfs: Prevent duplicate subsystem names.

For all child objects, creation comes through mkdir(2), so duplicate names
are prevented.

Subsystems, though, are registered by client drivers at init_module()/__init
time.  This patch prevents duplicate subsystem names.

Subject: ocfs2: move nlink check in ocfs2_mknod()

The dir nlink check in ocfs2_mknod() was being done outside of the cluster
lock, which means we could have been checking against a stale version of the
inode. Fix this by doing the check after the cluster lock instead.

Subject: ocfs2: implement directory read-ahead

Uptodate.c now knows about read-ahead buffers. Use some more aggressive
logic in ocfs2_readdir().

The two functions which currently use directory read-ahead are
ocfs2_find_entry() and ocfs2_readdir().

Subject: ocfs2: Remove overzealous BUG_ON()

The truncate code was never supposed to BUG() on an allocator it doesn't
know about, but rather to ignore it. Right now, this does nothing, but when
we change our allocation paths to use all suballocator files, this will
allow current versions of the fs module to work fine.

Subject: [CRYPTO] api: Fixed crypto_tfm context alignment

Previously the __aligned__ attribute was added to the crypto_tfm context
member to ensure it is alinged correctly on architectures such as arm.
Unfortunately kmalloc does not use the same minimum alignment rules as
gcc so this is useless.

This patch changes it to use kmalloc's minimum alignment.

Subject: [CRYPTO] twofish: Split out common c code

This patch splits up the twofish crypto routine into a common part ( key
setup  ) which will be uses by all twofish crypto modules ( generic-c , i586
assembler and x86_64 assembler ) and generic-c part. It also creates a new
header file which will be used by all 3 modules.

This eliminates all code duplication.

Correctness was verified with the tcrypt module and automated test scripts.

-/* The exp_to_poly and poly_to_exp tables are used to perform efficient
- * operations in GF(2^8) represented as GF(2)[x]/w(x) where
- * w(x)=x^8+x^6+x^3+x^2+1.  We care about doing that because it's part of the
- * definition of the RS matrix in the key schedule.  Elements of that field
- * are polynomials of degree not greater than 7 and all coefficients 0 or 1,
- * which can be represented naturally by bytes (just substitute x=2).  In that
- * form, GF(2^8) addition is the same as bitwise XOR, but GF(2^8)
- * multiplication is inefficient without hardware support.  To multiply
- * faster, I make use of the fact x is a generator for the nonzero elements,
- * so that every element p of GF(2)[x]/w(x) is either 0 or equal to (x)^n for
- * some n in 0..254.  Note that that caret is exponentiation in GF(2^8),
- * *not* polynomial notation.  So if I want to compute pq where p and q are
- * in GF(2^8), I can just say:
- *    1. if p=0 or q=0 then pq=0
- *    2. otherwise, find m and n such that p=x^m and q=x^n
- *    3. pq=(x^m)(x^n)=x^(m+n), so add m and n and find pq
- * The translations in steps 2 and 3 are looked up in the tables
- * poly_to_exp (for step 2) and exp_to_poly (for step 3).  To see this
- * in action, look at the CALC_S macro.  As additional wrinkles, note that
- * one of my operands is always a constant, so the poly_to_exp lookup on it
- * is done in advance; I included the original values in the comments so
- * readers can have some chance of recognizing that this *is* the RS matrix
- * from the Twofish paper.  I've only included the table entries I actually
- * need; I never do a lookup on a variable input of zero and the biggest
- * exponents I'll ever see are 254 (variable) and 237 (constant), so they'll
- * never sum to more than 491.	I'm repeating part of the exp_to_poly table
- * so that I don't have to do mod-255 reduction in the exponent arithmetic.
- * Since I know my constant operands are never zero, I only have to worry
- * about zero values in the variable operand, and I do it with a simple
- * conditional branch.	I know conditionals are expensive, but I couldn't
- * see a non-horrible way of avoiding them, and I did manage to group the
- * statements so that each if covers four group multiplications. */

+/* The exp_to_poly and poly_to_exp tables are used to perform efficient
+ * operations in GF(2^8) represented as GF(2)[x]/w(x) where
+ * w(x)=x^8+x^6+x^3+x^2+1.  We care about doing that because it's part of the
+ * definition of the RS matrix in the key schedule.  Elements of that field
+ * are polynomials of degree not greater than 7 and all coefficients 0 or 1,
+ * which can be represented naturally by bytes (just substitute x=2).  In that
+ * form, GF(2^8) addition is the same as bitwise XOR, but GF(2^8)
+ * multiplication is inefficient without hardware support.  To multiply
+ * faster, I make use of the fact x is a generator for the nonzero elements,
+ * so that every element p of GF(2)[x]/w(x) is either 0 or equal to (x)^n for
+ * some n in 0..254.  Note that that caret is exponentiation in GF(2^8),
+ * *not* polynomial notation.  So if I want to compute pq where p and q are
+ * in GF(2^8), I can just say:
+ *    1. if p=0 or q=0 then pq=0
+ *    2. otherwise, find m and n such that p=x^m and q=x^n
+ *    3. pq=(x^m)(x^n)=x^(m+n), so add m and n and find pq
+ * The translations in steps 2 and 3 are looked up in the tables
+ * poly_to_exp (for step 2) and exp_to_poly (for step 3).  To see this
+ * in action, look at the CALC_S macro.  As additional wrinkles, note that
+ * one of my operands is always a constant, so the poly_to_exp lookup on it
+ * is done in advance; I included the original values in the comments so
+ * readers can have some chance of recognizing that this *is* the RS matrix
+ * from the Twofish paper.  I've only included the table entries I actually
+ * need; I never do a lookup on a variable input of zero and the biggest
+ * exponents I'll ever see are 254 (variable) and 237 (constant), so they'll
+ * never sum to more than 491.	I'm repeating part of the exp_to_poly table
+ * so that I don't have to do mod-255 reduction in the exponent arithmetic.
+ * Since I know my constant operands are never zero, I only have to worry
+ * about zero values in the variable operand, and I do it with a simple
+ * conditional branch.	I know conditionals are expensive, but I couldn't
+ * see a non-horrible way of avoiding them, and I did manage to group the
+ * statements so that each if covers four group multiplications. */

Subject: [CRYPTO] twofish: Fix the priority

This patch adds a proper driver name and priority to the generic c
implemtation to allow coexistance of c and assembler modules.

Subject: [CRYPTO] twofish: i586 assembly version

The patch passed the trycpt tests and automated filesystem tests.
This rewrite resulted in some nice perfomance increase over my last patch.

Short summary of the tcrypt benchmarks:

Twofish Assembler vs. Twofish C (256bit 8kb block CBC)
encrypt: -33% Cycles
decrypt: -45% Cycles

Twofish Assembler vs. AES Assembler (128bit 8kb block CBC)
encrypt: +3%  Cycles
decrypt: -22% Cycles

Twofish Assembler vs. AES Assembler (256bit 8kb block CBC)
encrypt: -20% Cycles
decrypt: -36% Cycles

Full Output:
http://homepages.tu-darmstadt.de/~fritschi/twofish/tcrypt-speed-twofish-asm-i586.txt
http://homepages.tu-darmstadt.de/~fritschi/twofish/tcrypt-speed-twofish-c-i586.txt
http://homepages.tu-darmstadt.de/~fritschi/twofish/tcrypt-speed-aes-asm-i586.txt


Here is another bonnie++ benchmark with encrypted filesystems. All runs with
the twofish assembler modules max out the drivespeed. It should give some
idea what the module can do for encrypted filesystem performance even though
you can't see the full numbers.

Subject: [CRYPTO] twofish: x86-64 assembly version

The patch passed the trycpt tests and automated filesystem tests.
This rewrite resulted in some nice perfomance increase over my last patch.

Short summary of the tcrypt benchmarks:

Twofish Assembler vs. Twofish C (256bit 8kb block CBC)
encrypt: -27% Cycles
decrypt: -23% Cycles

Twofish Assembler vs. AES Assembler (128bit 8kb block CBC)
encrypt: +18%  Cycles
decrypt: +15% Cycles

Twofish Assembler vs. AES Assembler (256bit 8kb block CBC)
encrypt: -9% Cycles
decrypt: -8% Cycles

Full Output:
http://homepages.tu-darmstadt.de/~fritschi/twofish/tcrypt-speed-twofish-c-x86_64.txt
http://homepages.tu-darmstadt.de/~fritschi/twofish/tcrypt-speed-twofish-asm-x86_64.txt
http://homepages.tu-darmstadt.de/~fritschi/twofish/tcrypt-speed-aes-asm-x86_64.txt


Here is another bonnie++ benchmark with encrypted filesystems. Most runs maxed
out the hd. It should give some idea what the module can do for encrypted filesystem
performance even though you can't see the full numbers.

Subject: [CRYPTO] api: Rename crypto_alg_get to crypto_mod_get

The functions crypto_alg_get and crypto_alg_put operates on the crypto
modules rather than the algorithms.  Therefore it makes sense to call
them crypto_mod_get and crypto_alg_put respectively.

This is needed because we need to have real algorithm reference counters
for parameterised algorithms as they can be unregistered from below by
when their parameter algorithms are themselves unregistered.

Subject: [CRYPTO] api: Add crypto_alg reference counting

Up until now we've relied on module reference counting to ensure that the
crypto_alg structures don't disappear from under us.  This was good enough
as long as each crypto_alg came from exactly one module.

However, with parameterised crypto algorithms a crypto_alg object may need
two or more modules to operate.  This means that we need to count the
references to the crypto_alg object directly.

The header file linux/crypto.h is only needed by a few files so including
it in net/xfrm.h (which is included by half of the networking stack) is a
waste.  This patch moves it out of net/xfrm.h and into the specific header
files that actually need it.

Subject: [CRYPTO] api: Split out low-level API

The crypto API is made up of the part facing users such as IPsec and the
low-level part which is used by cryptographic entities such as algorithms.
This patch splits out the latter so that the two APIs are more clearly
delineated.  As a bonus the low-level API can now be modularised if all
algorithms are built as modules.

From 4cc7720cd165273b08a72b4193146dffee58e34b Mon Sep 17 00:00:00 2001
From: Herbert Xu <herbert@gondor.apana.org.au>
Date: Sun, 6 Aug 2006 21:16:34 +1000
Subject: [CRYPTO] api: Add template registration

A crypto_template generates a crypto_alg object when given a set of
parameters.  this patch adds the basic data structure fo templates
and code to handle their registration/deregistration.

From 2825982d9d66ebba4b532a07391dfbb357f71c5f Mon Sep 17 00:00:00 2001
From: Herbert Xu <herbert@gondor.apana.org.au>
Date: Sun, 6 Aug 2006 21:23:26 +1000
Subject: [CRYPTO] api: Added event notification

This patch adds a notifier chain for algorithm/template registration events.
This will be used to register compound algorithms such as cbc(aes).  In
future this will also be passed onto user-space through netlink.

Subject: [CRYPTO] api: Add cryptomgr

The cryptomgr module is a simple manager of crypto algorithm instances.
It ensures that parameterised algorithms of the type tmpl(alg) (e.g.,
cbc(aes)) are always created.

This is meant to satisfy the needs for most users.  For more complex
cases such as deeper combinations or multiple parameters, a netlink
module will be created which allows arbitrary expressions to be parsed
in user-space.

Subject: [CRYPTO] api: Allow algorithm lookup by type

This patch also adds the infrastructure to pick an algorithm based on
their type.  For example, this allows you to select the encryption
algorithm "aes", instead of any algorithm registered under the name
"aes".  For now this is only accessible internally.  Eventually it
will be made available through crypto_alloc_tfm.

Subject: [CRYPTO] api: Added spawns

Spawns lock a specific crypto algorithm in place.  They can then be used
with crypto_spawn_tfm to allocate a tfm for that algorithm.  When the base
algorithm of a spawn is deregistered, all its spawns will be automatically
removed.

Subject: [CRYPTO] sha: Add module aliases for sha1 / sha256

Crypto modules should be loadable by their .cra_driver_name, so
we should make MODULE_ALIAS()es with these names. This patch adds
aliases for SHA1 and SHA256 only as that's what we need for
PadLock-SHA driver.

Subject: [CRYPTO] padlock: Get rid of padlock-generic.c

Merge padlock-generic.c into padlock-aes.c and compile
AES as a standalone module. We won't make a monolithic
padlock.ko with all supported algorithms, instead we'll
compile each driver into its own module.

Subject: [CRYPTO] padlock: Add compatibility alias after rename

Whenever we rename modules we should add an alias to ensure that existing
users can still locate the new module.

This patch also gets rid of the now unused module function prototypes from
padlock.h.

Subject: [CRYPTO] padlock: Update private header file

PADLOCK_CRA_PRIORITY is shared between padlock-aes and padlock-sha
so it should be in the header.

On the other hand "struct cword" is only used in padlock-aes.c
so it's unnecessary to have it in padlock.h

Subject: [CRYPTO] padlock: Helper module padlock.ko

Compile a helper module padlock.ko that will try
to autoload all configured padlock algorithms.

This also provides backward compatibility with

Subject: [CRYPTO] crc32c: Fix unconventional setkey usage

The convention for setkey is that once it is set it should not change,
in particular, init must not wipe out the key set by it.  In fact, init
should always be used after setkey before any digestion is performed.

The only user of crc32c that sets the key is tcrypt.  This patch adds
the necessary init calls there.

Subject: [CRYPTO] api: Get rid of flags argument to setkey

Now that the tfm is passed directly to setkey instead of the ctx, we no
longer need to pass the &tfm->crt_flags pointer.

This patch also gets rid of a few unnecessary checks on the key length
for ciphers as the cipher layer guarantees that the key length is within
the bounds specified by the algorithm.

Rather than testing dia_setkey every time, this patch does it only once
during crypto_alloc_tfm.  The redundant check from crypto_digest_setkey
is also removed.

Subject: [CRYPTO] digest: Store temporary digest in tfm

When the final result location is unaligned, we store the digest in a
temporary buffer before copying it to the final location.  Currently
that buffer sits on the stack.  This patch moves it to an area in the
tfm, just like the CBC IV buffer.

Subject: [CRYPTO] tcrypt: Use test_hash for crc32c

Now that crc32c has been fixed to conform with standard digest semantics,
we can use test_hash for it.  I've turned the last test into a chunky
test.

From df89820ebd5bbf4f3c6b5f8ee7d9e983107f6a91 Mon Sep 17 00:00:00 2001
From: Herbert Xu <herbert@gondor.apana.org.au>

Subject: [CRYPTO] cipher: Removed special IV checks for ECB

This patch makes IV operations on ECB fail through nocrypt_iv rather than
calling BUG().  This is needed to generalise CBC/ECB using the template
mechanism.

Subject: [CRYPTO] api: Add common instance initialisation code

This patch adds the helpers crypto_get_attr_alg and crypto_alloc_instance
which can be used by simple one-argument templates like hmac to process
input parameters and allocate instances.

Subject: [CRYPTO] api: Added crypto_alloc_base

Up until now all crypto transforms have been of the same type, struct
crypto_tfm, regardless of whether they are ciphers, digests, or other
types.  As a result of that, we check the types at run-time before
each crypto operation.

This is rather cumbersome.  We could instead use different C types for
each crypto type to ensure that the correct types are used at compile
time.  That is, we would have crypto_cipher/crypto_digest instead of
just crypto_tfm.  The appropriate type would then be required for the
actual operations such as crypto_digest_digest.

Now that we have the type/mask fields when looking up algorithms, it
is easy to request for an algorithm of the precise type that the user
wants.  However, crypto_alloc_tfm currently does not expose these new
attributes.

This patch introduces the function crypto_alloc_base which will carry
these new parameters.  It will be renamed to crypto_alloc_tfm once
all existing users have been converted.

Subject: [CRYPTO] api: Feed flag directly to crypto_yield

The sleeping flag used to determine whether crypto_yield can actually
yield is really a per-operation flag rather than a per-tfm flag.  This
patch changes crypto_yield to take a flag directly so that we can start
using a per-operation flag instead the tfm flag.

Subject: [CRYPTO] api: Added crypto_type support

This patch adds the crypto_type structure which will be used for all new
crypto algorithm types, beginning with block ciphers.

The primary purpose of this abstraction is to allow different crypto_type
objects for crypto algorithms of the same type, in particular, there will
be a different crypto_type objects for asynchronous algorithms.

Subject: [CRYPTO] cipher: Added encrypt_one/decrypt_one

This patch adds two new operations for the simple cipher that encrypts or
decrypts a single block at a time.  This will be the main interface after
the existing block operations have moved over to the new block ciphers.

It also adds the crypto_cipher type which is currently only used on the
new operations but will be extended to setkey as well once existing users
have been converted to use block ciphers where applicable.

Subject: [CRYPTO] scatterwalk: Prepare for block ciphers

This patch prepares the scatterwalk code for use by the new block cipher
type.

Firstly it halves the size of scatter_walk on 32-bit platforms.  This
is important as we allocate at least two of these objects on the stack
for each block cipher operation.

It also exports the symbols since the block cipher code can be built as
a module.

Finally there is a hack in scatterwalk_unmap that relies on progress
being made.  Unfortunately, for hardware crypto we can't guarantee
progress to be made since the hardware can fail.

So this also gets rid of the hack by not advancing the address returned
by scatterwalk_map.

Subject: [CRYPTO] cipher: Added block cipher type

This patch adds the new type of block ciphers.  Unlike current cipher
algorithms which operate on a single block at a time, block ciphers
operate on an arbitrarily long linear area of data.  As it is block-based,
it will skip any data remaining at the end which cannot form a block.

The block cipher has one major difference when compared to the existing
block cipher implementation.  The sg walking is now performed by the
algorithm rather than the cipher mid-layer.  This is needed for drivers
that directly support sg lists.  It also improves performance for all
algorithms as it reduces the total number of indirect calls by one.

In future the existing cipher algorithm will be converted to only have
a single-block interface.  This will be done after all existing users
have switched over to the new block cipher type.

From db131ef9084110d9e82549c0a627e157e8bb99d7 Mon Sep 17 00:00:00 2001

Subject: [CRYPTO] cipher: Added block ciphers for CBC/ECB

This patch adds two block cipher algorithms, CBC and ECB.  These
are implemented as templates on top of existing single-block cipher
algorithms.  They invoke the single-block cipher through the new
encrypt_one/decrypt_one interface.

This also optimises the in-place encryption and decryption to remove
the cost of an IV copy each round.

Subject: [CRYPTO] padlock: Added block cipher versions of CBC/ECB

This patch adds block cipher algorithms for cbc(aes) and ecb(aes) for
the PadLock device.  Once all users to the old cipher type have been
converted the old cbc/ecb PadLock operations will be removed.

Subject: [CRYPTO] tcrypt: Use block ciphers where applicable

From 69affe7fc52c14e4b81408a2076e9e58ba4af60a Mon Sep 17 00:00:00 2001
From: Herbert Xu <herbert@gondor.apana.org.au>
Date: Thu, 21 Sep 2006 11:45:53 +1000
Subject: [BLOCK] cryptoloop: Use block ciphers where applicable

This patch converts cryptoloop to use the new block cipher type where
applicable.  As a result the ECB-specific and CBC-specific transfer
functions have been merged.

Subject: [BLOCK] dm-crypt: Use block ciphers where applicable

This patch converts dm-crypt to use the new block cipher type where
applicable.  It also changes simple cipher operations to use the new
encrypt_one/decrypt_one interface.

Subject: [IPSEC]: Add compatibility algorithm name support

This patch adds a compatibility name field for each IPsec algorithm.  This
is needed when parameterised algorithms are used.  For example, "md5" will
become "hmac(md5)", and "aes" will become "cbc(aes)".

From f12cc2090d721647c23dfce20834f4306db3b77d Mon Sep 17 00:00:00 2001
From: Herbert Xu <herbert@gondor.apana.org.au>
Date: Tue, 22 Aug 2006 20:36:13 +1000
Subject: [CRYPTO] users: Use block ciphers where applicable

This patch converts all remaining users to use the new block cipher type
where applicable.  It also changes all simple cipher operations to use
the new encrypt_one/decrypt_one interface.

Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

From efcf8023e299be605f217dc2c1b2754b5534569c Mon Sep 17 00:00:00 2001
From: Herbert Xu <herbert@gondor.apana.org.au>
Date: Sat, 5 Aug 2006 16:28:19 +1000
Subject: [CRYPTO] drivers: Remove obsolete block cipher operations

This patch removes obsolete block operations of the simple cipher type
from drivers.  These were preserved so that existing users can make a
smooth transition.  Now that the transition is complete, they are no
longer needed.

Subject: [PATCH] scatterlist: Add const to sg_set_buf/sg_init_one pointer
 argument

This patch adds a const modifier to the buf argument of sg_set_buf and
sg_init_one.  This lets people call it with pointers that are const.

Subject: [CRYPTO] api: Mark parts of cipher interface as deprecated

Mark the parts of the cipher interface that have been replaced by
block ciphers as deprecated.  Thanks to Andrew Morton for suggesting
doing this before removing them completely.

From 055bcee3102dc35f019b69df9c2618e9d6dd1c09 Mon Sep 17 00:00:00 2001
From: Herbert Xu <herbert@gondor.apana.org.au>

Subject: [CRYPTO] digest: Added user API for new hash type

The existing digest user interface is inadequate for support asynchronous
operations.  For one it doesn't return a value to indicate success or
failure, nor does it take a per-operation descriptor which is essential
for the issuing of requests while other requests are still outstanding.

This patch is the first in a series of steps to remodel the interface
for asynchronous operations.

For the ease of transition the new interface will be known as "hash"
while the old one will remain as "digest".

This patch also changes sg_next to allow chaining.

Subject: [CRYPTO] hmac: Add crypto template implementation

This patch rewrites HMAC as a crypto template.  This means that HMAC is no
longer a hard-coded part of the API.  It's now a template that generates
standard digest algorithms like any other.

The old HMAC is preserved until all current users are converted.

The same structure can be used by other MACs such as AES-XCBC-MAC.

Subject: [CRYPTO] tcrypt: Use HMAC template and hash interface

This patch converts tcrypt to use the new HMAC template rather than the
hard-coded version of HMAC.  It also converts all digest users to use
the new cipher interface.

From 07d4ee583e21830ec5604d31f65cdc60a6eca19e Mon Sep 17 00:00:00 2001
From: Herbert Xu <herbert@gondor.apana.org.au>
Date: Sun, 20 Aug 2006 14:24:50 +1000
Subject: [IPSEC]: Use HMAC template and hash interface

This patch converts IPsec to use the new HMAC template.  The names of
existing simple digest algorithms may still be used to refer to their
HMAC composites.

The same structure can be used by other MACs such as AES-XCBC-MAC.

This patch also switches from the digest interface to hash.

From 35058687912aa2f0b4554383cc10be4e0683b9a4 Mon Sep 17 00:00:00 2001
From: Herbert Xu <herbert@gondor.apana.org.au>
Date: Thu, 24 Aug 2006 19:10:20 +1000
Subject: [CRYPTO] users: Use crypto_hash interface instead of crypto_digest

This patch converts all remaining crypto_digest users to use the new
crypto_hash interface.

Subject: [CRYPTO] api: Add crypto_comp and crypto_has_*

This patch adds the crypto_comp type to complete the compile-time checking
conversion.  The functions crypto_has_alg and crypto_has_cipher, etc. are
also added to replace crypto_alg_available.

Subject: [CRYPTO] padlock: Convert padlock-sha to use crypto_hash

This patch converts padlock-sha to use crypto_hash for its fallback.
It also changes the fallback selection to use selection by type instead
of name.  This is done through the new CRYPTO_ALG_NEED_FALLBACK bit,
which is set if and only if an algorithm needs a fallback of the same
type.

Subject: [netdrvr] mv643xx_eth: fix obvious typo, which caused build breakage

The last minute fix submitted by the author fixed a bug, but
broke the driver build.

Noticed by Al Viro, since I can't build on said platform.

This fixes most of the issues with exported headers on CRIS, although
we do still need to deal with the asm/arch symlink.

Subject: [POWERPC] Add AT_PLATFORM value for Xilinx Virtex-4 FX

Jakub noticed the cputable.c entry for Xilinx Virtex-4 FX was missing
a .platform value, so the AT_PLATFORM value wouldn't be set correctly.
This adds it.

The stack frame address was being printed incorrectly in the backtrace
option of XMON on PPC.  This patch fixes it to print the actual stack
address instead of the address of the local variable that contains it.

Subject: [POWERPC] EEH: balance pcidev_get/put calls

This corrects a pci_dev get/put imbalance that can occur only in
highly unlikely situations (kmalloc failures, pci devices with
overlapping resource addresses).  No actual failures seen, this was
spotted during code review.

Subject: [POWERPC] EEH: support MMIO enable recovery step

Update to the PowerPC PCI error recovery code.

Add code to enable MMIO if a device driver reports that it is capable
of recovering on its own.  One anticipated use of this having a device
driver enable MMIO so that it can take a register dump, which might
then be followed by the device driver requesting a full reset.

Subject: [POWERPC] Remove DISCONTIGMEM cruft from page.h

This looks like cruft to me, these functions don't exist AFAICT,
and I can't see that it's possible to even enable DISCONTIGMEM on
powerpc anymore. CC'ing some folks who might know better, based on
the who-touched-it-last principle.

Subject: [POWERPC] powerpc: fix building gdb against asm/ptrace.h

Ulrich Weigand found a bug with the current version of the
asm-powerpc/ptrace.h that prevents building at least the
SPU target version of gdb, since some ptrace opcodes are
not defined.

The problem seems to have originated in the merging of 32 and
64 bit versions of that file, the problem is that some opcodes
are only valid on 64 bit kernels, but are also used by 32 bit
programs, so they can't depends on the __powerpc64__ symbol.

Subject: [POWERPC] Maple U3 HT - reject inappropriate config space access

When there is a PCI-X mode 2 capable device behind the HT<->PCI-X
bridge, the pci core decides that the device has the extended 4K
config space, even though the bus is not operating in mode 2.  This is
because the u3_ht pci ops silently accept offsets greater than 255 but
use only the 8 least significant bits, which means reading at offset
0x100 gets the data at offset 0x0, and causes confusion for lspci.

Reject accesses to configuration space offsets greater than 255.

Subject: [POWERPC] Demacrofy arch/powerpc/platforms/maple/pci.c

Noticed that the U3_*CFA macros have some typos:

#define U3_HT_CFA0(devfn, off)		\
		((((unsigned long)devfn) << 8) | offset)

(refers to offset rather than off)

#define U3_AGP_CFA0(devfn, off)	\
	((1 << (unsigned long)PCI_SLOT(dev_fn)) \
	| (((unsigned long)PCI_FUNC(dev_fn)) << 8) \

(refers to dev_fn rather than devfn)

Things happen to work, but there doesn't seem to be any reason these
shouldn't be functions.  Overall behavior should be unchanged.

Looks like a workaround for old bogus OF bitrot...  This fixes it and
hence fixes boot on some performa machines.

Subject: [MTD] Unlock NOR flash automatically where necessary
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Introduce the MTD_STUPID_LOCK flag which indicates that the flash chip is
always locked after power-up, so all sectors need to be unlocked before it
is usable.

If this flag is set, and the chip provides an unlock() operation,
mtd_add_device will unlock the whole MTD device if it's writeable.  This
means that non-writeable partitions will stay locked.

Set MTD_STUPID_LOCK in fixup_use_atmel_lock() so that these chips will work
as expected.

We certainly don't need the check for Linux version > 2.5.2, and in fact
we can also live without the __ECOS check, since we can just add it back
in the eCos git tree which is automatically derived from the Linux fs/jffs2
subdirectory in the upstream git tree.

From 25f0c659fe64832d8ee06aa623fffaad708dcf8b Mon Sep 17 00:00:00 2001

Subject: ioremap balanced with iounmap for drivers/mtd subsystem

ioremap must be balanced by an iounmap and failing to do so can result
in a memory leak.

Tested (compilation only) with:
- allmodconfig
- Modifying drivers/mtd/maps/Kconfig and drivers/mtd/nand/Kconfig to
make sure that the changed file is compiling without warning

Subject: [MTD] Remove iq80310 map driver

The iq80310 mtd map driver depends on ARCH_IQ80310, which isn't
defined anywhere in the tree (as we don't have 80310 support), and
furthermore, everything the driver does can be done with physmap
instead.

- *	 it into main memory as that would simply reduce performance
- *	 on the system.  Using it as a block device allows us to use
- *	 it as high speed swap or for a high speed disk device of some

- *	 embedded market I might add.

  * Notes:
- *	 Due to what I assume is more buggy SROM, the 64M PMC551 I

- *	 This is slightly annoying since the BAR0 size reflects the
- *	 aperture size, not the dram size, and the V370PDC supplies no
- *	 other method for memory size discovery.  This problem is
- *	 mostly only relevant when compiled as a module, as the
- *	 unloading of the module with an aperture size smaller then
- *	 the ram will cause the driver to detect the onboard memory
- *	 size to be equal to the aperture size when the module is
- *	 reloaded.  Soooo, to help, the module supports an msize
- *	 option to allow the specification of the onboard memory, and
- *	 an asize option, to allow the specification of the aperture
- *	 size.  The aperture must be equal to or less then the memory
- *	 size, the driver will correct this if you screw it up.  This
- *	 problem is not relevant for compiled in drivers as compiled

This reverts commit 668040fcd1e06fc3e68a92708cbdfa5a52c37d3c.

The 'flags' field of the struct request is 'unsigned long'. Quite
how Randy came to see 'long int format, different type arg' I don't
know, but it doesn't seem to be the case any more.

Subject: [MLSXFRM]: Granular IPSec associations for use in MLS environments

The current approach to labeling Security Associations for SELinux
purposes uses a one-to-one mapping between xfrm policy rules and
security associations.

This doesn't address the needs of real world MLS (Multi-level System,
traditional Bell-LaPadula) environments where a single xfrm policy
rule (pertaining to a range, classified to secret for example) might
need to map to multiple Security Associations (one each for
classified, secret, top secret and all the compartments applicable to
these security levels).

This patch set addresses the above problem by allowing for the mapping
of a single xfrm policy rule to multiple security associations, with
each association used in the security context it is defined for. It
also includes the security context to be used in IKE negotiation in
the acquire messages sent to the IKE daemon so that a unique SA can be
negotiated for each unique security context. A couple of bug fixes are
also included; checks to make sure the SAs used by a packet match
policy (security context-wise) on the inbound and also that the bundle
used for the outbound matches the security context of the flow. This
patch set also makes the use of the SELinux sid in flow cache lookups
seemless by including the sid in the flow key itself. Also, open
requests as well as connection-oriented child sockets are labeled
automatically to be at the same level as the peer to allow for use of
appropriately labeled IPSec associations.

Description of changes:

A "sid" member has been added to the flow cache key resulting in the
sid being available at all needed locations and the flow cache lookups
automatically using the sid. The flow sid is derived from the socket
on the outbound and the SAs (unlabeled where an SA was not used) on
the inbound.

Outbound case:
1. Find policy for the socket.

2. OLD: Find an SA that matches the policy.
 NEW: Find an SA that matches BOTH the policy and the flow/socket.
   This is necessary since not every SA that matches the policy
   can be used for the flow/socket. Consider policy range Secret-TS,
   and SAs each for Secret and TS. We don't want a TS socket to
   use the Secret SA. Hence the additional check for the SA Vs. flow/socket.

3. NEW: When looking thru bundles for a policy, make sure the
        flow/socket can use the bundle. If a bundle is not found,
        create one, calling for IKE if necessary. If using IKE,
        include the security context in the acquire message to the IKE
        daemon.

Inbound case:
1. OLD: Find policy for the socket.
 NEW: Find policy for the incoming packet based on the sid of the
      SA(s) it used or the unlabeled sid if no SAs were
      used. (Consider a case where a socket is "authorized" for two
      policies (unclassified-confidential, secret-top_secret). If the
      packet has come in using a secret SA, we really ought to be
      using the latter policy (secret-top_secret).)

2. OLD: BUG: No check to see if the SAs used by the packet agree with
             the policy sec_ctx-wise.

             (It was indicated in selinux_xfrm_sock_rcv_skb() that
              this was being accomplished by
              (x->id.spi == tmpl->id.spi || !tmpl->id.spi) in xfrm_state_ok,
	      but it turns out tmpl->id.spi
              would normally be zero (unless xfrm policy rules specify one
              at the template level, which they usually don't).
 NEW: The socket is checked for access to the SAs used (based on the
      sid of the SAs) in selinux_xfrm_sock_rcv_skb().

Forward case:
 This would be Step 1 from the Inbound case, followed by Steps 2 and 3
from the Outbound case.

Outstanding items/issues:

- Timewait acknowledgements and such are generated in the
  current/upstream implementation using a NULL socket resulting in the
  any_socket sid (SYSTEM_HIGH) to be used. This problem is not addressed
  by this patch set.

This patch: Add new flask definitions to SELinux

Adds a new avperm "polmatch" to arbitrate flow/state access to a xfrm
policy rule.

Subject: [MLSXFRM]: Define new SELinux service routine

This defines a routine that combines the Type Enforcement portion of
one sid with the MLS portion from the other sid to arrive at a new
sid. This would be used to define a sid for a security association
that is to be negotiated by IKE as well as for determing the sid for
open requests and connection-oriented child sockets.

Subject: [MLSXFRM]: Add security sid to sock

This adds security for IP sockets at the sock level. Security at the
sock level is needed to enforce the SELinux security policy for
security associations even when a sock is orphaned (such as in the TCP
LAST_ACK state).

This will also be used to enforce SELinux controls over data arriving
at or leaving a child socket while it's still waiting to be accepted.

Subject: [MLSXFRM]: Add security context to acquire messages using netlink

This includes the security context of a security association created
for use by IKE in the acquire messages sent to IKE daemons using
netlink/xfrm_user. This would allow the daemons to include the
security context in the negotiation, so that the resultant association
is unique to that security context.

Subject: [MLSXFRM]: Add flow labeling

This labels the flows that could utilize IPSec xfrms at the points the
flows are defined so that IPSec policy and SAs at the right label can
be used.

The following protos are currently not handled, but they should
continue to be able to use single-labeled IPSec like they currently
do.

ipmr
ip_gre
ipip
igmp
sit
sctp
ip6_tunnel (IPv6 over IPv6 tunnel device)
decnet

Subject: [MLSXFRM]: Auto-labeling of child sockets

This automatically labels the TCP, Unix stream, and dccp child sockets
as well as openreqs to be at the same MLS level as the peer. This will
result in the selection of appropriately labeled IPSec Security
Associations.

This also uses the sock's sid (as opposed to the isec sid) in SELinux
enforcement of secmark in rcv_skb and postroute_last hooks.

Subject: [MLSXFRM]: Fix build with SECURITY_NETWORK_XFRM disabled.

The following patch will fix the build problem (encountered by Andrew
Morton) when SECURITY_NETWORK_XFRM is not enabled.

As compared to git-net-selinux_xfrm_decode_session-build-fix.patch in
-mm, this patch sets the return parameter sid to SECSID_NULL in
selinux_xfrm_decode_session() and handles this value in the caller
selinux_inet_conn_request() appropriately.

Subject: [NetLabel]: documentation

Documentation for the NetLabel system, this includes a basic overview
of how NetLabel works, how LSM developers can integrate it into their
favorite LSM, as well as documentation on the CIPSO related sysctl
variables.  Also, due to the difficulty of finding expired IETF
drafts, I am including the IETF CIPSO draft that is the basis of the
NetLabel CIPSO implementation.

+NetLabel CIPSO/IPv4 Protocol Engine
+==============================================================================
+Paul Moore, paul.moore@hp.com
+
+May 17, 2006
+
+ * Overview
+
+The NetLabel CIPSO/IPv4 protocol engine is based on the IETF Commercial IP
+Security Option (CIPSO) draft from July 16, 1992.  A copy of this draft can be
+found in this directory, consult '00-INDEX' for the filename.  While the IETF
+draft never made it to an RFC standard it has become a de-facto standard for
+labeled networking and is used in many trusted operating systems.
+
+ * Outbound Packet Processing
+
+The CIPSO/IPv4 protocol engine applies the CIPSO IP option to packets by
+adding the CIPSO label to the socket.  This causes all packets leaving the
+system through the socket to have the CIPSO IP option applied.  The socket's
+CIPSO label can be changed at any point in time, however, it is recommended
+that it is set upon the socket's creation.  The LSM can set the socket's CIPSO
+label by using the NetLabel security module API; if the NetLabel "domain" is
+configured to use CIPSO for packet labeling then a CIPSO IP option will be
+generated and attached to the socket.
+
+ * Inbound Packet Processing
+
+The CIPSO/IPv4 protocol engine validates every CIPSO IP option it finds at the
+IP layer without any special handling required by the LSM.  However, in order
+to decode and translate the CIPSO label on the packet the LSM must use the
+NetLabel security module API to extract the security attributes of the packet.
+This is typically done at the socket layer using the 'socket_sock_rcv_skb()'
+LSM hook.
+
+ * Label Translation
+
+The CIPSO/IPv4 protocol engine contains a mechanism to translate CIPSO security
+attributes such as sensitivity level and category to values which are
+appropriate for the host.  These mappings are defined as part of a CIPSO
+Domain Of Interpretation (DOI) definition and are configured through the
+NetLabel user space communication layer.  Each DOI definition can have a
+different security attribute mapping table.
+
+ * Label Translation Cache
+
+The NetLabel system provides a framework for caching security attribute
+mappings from the network labels to the corresponding LSM identifiers.  The
+CIPSO/IPv4 protocol engine supports this caching mechanism.

+
+                 COMMERCIAL IP SECURITY OPTION (CIPSO 2.2)
+
+
+
+1.    Status
+
+This Internet Draft provides the high level specification for a Commercial
+IP Security Option (CIPSO).  This draft reflects the version as approved by
+the CIPSO IETF Working Group.  Distribution of this memo is unlimited.
+
+This document is an Internet Draft.  Internet Drafts are working documents
+of the Internet Engineering Task Force (IETF), its Areas, and its Working
+Groups. Note that other groups may also distribute working documents as
+Internet Drafts.
+
+Internet Drafts are draft documents valid for a maximum of six months.
+Internet Drafts may be updated, replaced, or obsoleted by other documents
+at any time.  It is not appropriate to use Internet Drafts as reference
+material or to cite them other than as a "working draft" or "work in
+progress."
+
+Please check the I-D abstract listing contained in each Internet Draft
+directory to learn the current status of this or any other Internet Draft.
+
+
+
+
+2.    Background
+
+Currently the Internet Protocol includes two security options.  One of
+these options is the DoD Basic Security Option (BSO) (Type 130) which allows
+IP datagrams to be labeled with security classifications.  This option
+provides sixteen security classifications and a variable number of handling
+restrictions.  To handle additional security information, such as security
+categories or compartments, another security option (Type 133) exists and
+is referred to as the DoD Extended Security Option (ESO).  The values for
+the fixed fields within these two options are administered by the Defense
+Information Systems Agency (DISA).
+
+Computer vendors are now building commercial operating systems with
+mandatory access controls and multi-level security.  These systems are
+no longer built specifically for a particular group in the defense or
+intelligence communities.  They are generally available commercial systems
+for use in a variety of government and civil sector environments.
+
+The small number of ESO format codes can not support all the possible
+applications of a commercial security option.  The BSO and ESO were
+designed to only support the United States DoD.  CIPSO has been designed
+to support multiple security policies.  This Internet Draft provides the
+format and procedures required to support a Mandatory Access Control
+security policy.  Support for additional security policies shall be
+defined in future RFCs.

+
+3.    CIPSO Format
+
+Option type: 134 (Class 0, Number 6, Copy on Fragmentation)
+Option length: Variable
+
+This option permits security related information to be passed between
+systems within a single Domain of Interpretation (DOI).  A DOI is a
+collection of systems which agree on the meaning of particular values
+in the security option.  An authority that has been assigned a DOI
+identifier will define a mapping between appropriate CIPSO field values
+and their human readable equivalent.  This authority will distribute that
+mapping to hosts within the authority's domain.  These mappings may be
+sensitive, therefore a DOI authority is not required to make these
+mappings available to anyone other than the systems that are included in
+the DOI.
+
+This option MUST be copied on fragmentation.  This option appears at most
+once in a datagram.  All multi-octet fields in the option are defined to be
+transmitted in network byte order.  The format of this option is as follows:
+
++----------+----------+------//------+-----------//---------+
+| 10000110 | LLLLLLLL | DDDDDDDDDDDD | TTTTTTTTTTTTTTTTTTTT |
++----------+----------+------//------+-----------//---------+
+
+  TYPE=134    OPTION    DOMAIN OF               TAGS
+              LENGTH    INTERPRETATION
+
+
+                Figure 1. CIPSO Format
+
+
+3.1    Type
+
+This field is 1 octet in length.  Its value is 134.
+
+
+3.2    Length
+
+This field is 1 octet in length.  It is the total length of the option
+including the type and length fields.  With the current IP header length
+restriction of 40 octets the value of this field MUST not exceed 40.
+
+
+3.3    Domain of Interpretation Identifier
+
+This field is an unsigned 32 bit integer.  The value 0 is reserved and MUST
+not appear as the DOI identifier in any CIPSO option.  Implementations
+should assume that the DOI identifier field is not aligned on any particular
+byte boundary.
+
+To conserve space in the protocol, security levels and categories are
+represented by numbers rather than their ASCII equivalent.  This requires
+a mapping table within CIPSO hosts to map these numbers to their
+corresponding ASCII representations.  Non-related groups of systems may

+
+
+have their own unique mappings.  For example, one group of systems may
+use the number 5 to represent Unclassified while another group may use the
+number 1 to represent that same security level.  The DOI identifier is used
+to identify which mapping was used for the values within the option.
+
+
+3.4    Tag Types
+
+A common format for passing security related information is necessary
+for interoperability.  CIPSO uses sets of "tags" to contain the security
+information relevant to the data in the IP packet.  Each tag begins with
+a tag type identifier followed by the length of the tag and ends with the
+actual security information to be passed.  All multi-octet fields in a tag
+are defined to be transmitted in network byte order.  Like the DOI
+identifier field in the CIPSO header, implementations should assume that
+all tags, as well as fields within a tag, are not aligned on any particular
+octet boundary.   The tag types defined in this document contain alignment
+bytes to assist alignment of some information, however alignment can not
+be guaranteed if CIPSO is not the first IP option.
+
+CIPSO tag types 0 through 127 are reserved for defining standard tag
+formats.  Their definitions will be published in RFCs.  Tag types whose
+identifiers are greater than 127 are defined by the DOI authority and may
+only be meaningful in certain Domains of Interpretation.  For these tag
+types, implementations will require the DOI identifier as well as the tag
+number to determine the security policy and the format associated with the
+tag.  Use of tag types above 127 are restricted to closed networks where
+interoperability with other networks will not be an issue.  Implementations
+that support a tag type greater than 127 MUST support at least one DOI that
+requires only tag types 1 to 127.
+
+Tag type 0 is reserved. Tag types 1, 2, and 5 are defined in this
+Internet Draft.  Types 3 and 4 are reserved for work in progress.
+The standard format for all current and future CIPSO tags is shown below:
+
++----------+----------+--------//--------+
+| TTTTTTTT | LLLLLLLL | IIIIIIIIIIIIIIII |
++----------+----------+--------//--------+
+    TAG       TAG         TAG
+    TYPE      LENGTH      INFORMATION
+
+    Figure 2:  Standard Tag Format
+
+In the three tag types described in this document, the length and count
+restrictions are based on the current IP limitation of 40 octets for all
+IP options.  If the IP header is later expanded, then the length and count
+restrictions specified in this document may increase to use the full area
+provided for IP options.
+
+
+3.4.1    Tag Type Classes
+
+Tag classes consist of tag types that have common processing requirements
+and support the same security policy.  The three tags defined in this
+Internet Draft belong to the Mandatory Access Control (MAC) Sensitivity

+
+
+3.4.2    Tag Type 1
+
+This is referred to as the "bit-mapped" tag type.  Tag type 1 is included
+in the MAC Sensitivity tag type class.  The format of this tag type is as
+follows:

+
+
+3.4.2.2    Tag Length
+
+This field is 1 octet in length.  It is the total length of the tag type
+including the type and length fields.  With the current IP header length
+restriction of 40 bytes the value within this field is between 4 and 34.
+
+
+3.4.2.3    Alignment Octet
+
+This field is 1 octet in length and always has the value of 0.  Its purpose
+is to align the category bitmap field on an even octet boundary.  This will
+speed many implementations including router implementations.
+
+
+3.4.2.4    Sensitivity Level
+
+This field is 1 octet in length.  Its value is from 0 to 255.  The values
+are ordered with 0 being the minimum value and 255 representing the maximum
+value.
+
+
+3.4.2.5    Bit Map of Categories
+
+The length of this field is variable and ranges from 0 to 30 octets.  This
+provides representation of categories 0 to 239.  The ordering of the bits
+is left to right or MSB to LSB.  For example category 0 is represented by
+the most significant bit of the first byte and category 15 is represented
+by the least significant bit of the second byte.  Figure 4 graphically
+shows this ordering.  Bit N is binary 1 if category N is part of the label
+for the datagram, and bit N is binary 0 if category N is not part of the
+label.  Except for the optimized tag 1 format described in the next section,

+
+3.4.2.6    Optimized Tag 1 Format
+
+Routers work most efficiently when processing fixed length fields.  To
+support these routers there is an optimized form of tag type 1.  The format
+does not change.  The only change is to the category bitmap which is set to
+a constant length of 10 octets.  Trailing octets required to fill out the 10
+octets are zero filled.  Ten octets, allowing for 80 categories, was chosen
+because it makes the total length of the CIPSO option 20 octets.  If CIPSO
+is the only option then the option will be full word aligned and additional
+filler octets will not be required.
+
+
+3.4.3    Tag Type 2
+
+This is referred to as the "enumerated" tag type.  It is used to describe
+large but sparsely populated sets of categories.  Tag type 2 is in the MAC
+Sensitivity tag type class.  The format of this tag type is as follows:
+
++----------+----------+----------+----------+-------------//-------------+

+are ordered with 0 being the minimum value and 255 representing the
+maximum value.
+
+
+3.4.3.5    Enumerated Categories
+
+In this tag, categories are represented by their actual value rather than
+by their position within a bit field.  The length of each category is 2
+octets.  Up to 15 categories may be represented by this tag.  Valid values
+for categories are 0 to 65534.  Category 65535 is not a valid category
+value.  The categories MUST be listed in ascending order within the tag.
+
+
+3.4.4    Tag Type 5
+
+This is referred to as the "range" tag type.  It is used to represent
+labels where all categories in a range, or set of ranges, are included
+in the sensitivity label.  Tag type 5 is in the MAC Sensitivity tag type
+class.  The format of this tag type is as follows:
+
++----------+----------+----------+----------+------------//-------------+

+
+
+
+3.4.4.4    Sensitivity Level
+
+This field is 1 octet in length. Its value is from 0 to 255.  The values
+are ordered with 0 being the minimum value and 255 representing the maximum
+value.
+
+
+3.4.4.5    Category Ranges
+
+A category range is a 4 octet field comprised of the 2 octet index of the
+highest numbered category followed by the 2 octet index of the lowest
+numbered category.  These range endpoints are inclusive within the range of
+categories.  All categories within a range are included in the sensitivity
+label.  This tag may contain a maximum of 7 category pairs.  The bottom
+category endpoint for the last pair in the tag MAY be omitted and SHOULD be
+assumed to be 0.  The ranges MUST be non-overlapping and be listed in
+descending order.  Valid values for categories are 0 to 65534.  Category
+65535 is not a valid category value.
+
+
+3.4.5     Minimum Requirements
+
+A CIPSO implementation MUST be capable of generating at least tag type 1 in
+the non-optimized form.  In addition, a CIPSO implementation MUST be able
+to receive any valid tag type 1 even those using the optimized tag type 1
+format.
+
+
+4.    Configuration Parameters
+
+The configuration parameters defined below are required for all CIPSO hosts,
+gateways, and routers that support multiple sensitivity labels.  A CIPSO
+host is defined to be the origination or destination system for an IP
+datagram.  A CIPSO gateway provides IP routing services between two or more
+IP networks and may be required to perform label translations between
+networks.  A CIPSO gateway may be an enhanced CIPSO host or it may just
+provide gateway services with no end system CIPSO capabilities.  A CIPSO
+router is a dedicated IP router that routes IP datagrams between two or more
+IP networks.
+
+An implementation of CIPSO on a host MUST have the capability to reject a
+datagram for reasons that the information contained can not be adequately
+protected by the receiving host or if acceptance may result in violation of
+the host or network security policy.  In addition, a CIPSO gateway or router
+MUST be able to reject datagrams going to networks that can not provide
+adequate protection or may violate the network's security policy.  To
+provide this capability the following minimal set of configuration
+parameters are required for CIPSO implementations:
+
+HOST_LABEL_MAX - This parameter contains the maximum sensitivity label that
+a CIPSO host is authorized to handle.  All datagrams that have a label
+greater than this maximum MUST be rejected by the CIPSO host.  This
+parameter does not apply to CIPSO gateways or routers.  This parameter need
+not be defined explicitly as it can be implicitly derived from the
+PORT_LABEL_MAX parameters for the associated interfaces.

+
+
+
+
+HOST_LABEL_MIN - This parameter contains the minimum sensitivity label that
+a CIPSO host is authorized to handle.  All datagrams that have a label less
+than this minimum MUST be rejected by the CIPSO host.  This parameter does
+not apply to CIPSO gateways or routers.  This parameter need not be defined
+explicitly as it can be implicitly derived from the PORT_LABEL_MIN
+parameters for the associated interfaces.
+
+PORT_LABEL_MAX - This parameter contains the maximum sensitivity label for
+all datagrams that may exit a particular network interface port.  All
+outgoing datagrams that have a label greater than this maximum MUST be
+rejected by the CIPSO system.  The label within this parameter MUST be
+less than or equal to the label within the HOST_LABEL_MAX parameter.  This
+parameter does not apply to CIPSO hosts that support only one network port.
+
+PORT_LABEL_MIN - This parameter contains the minimum sensitivity label for
+all datagrams that may exit a particular network interface port.  All
+outgoing datagrams that have a label less than this minimum MUST be
+rejected by the CIPSO system.  The label within this parameter MUST be
+greater than or equal to the label within the HOST_LABEL_MIN parameter.
+This parameter does not apply to CIPSO hosts that support only one network
+port.
+
+PORT_DOI - This parameter is used to assign a DOI identifier value to a
+particular network interface port.  All CIPSO labels within datagrams
+going out this port MUST use the specified DOI identifier.  All CIPSO
+hosts and gateways MUST support either this parameter, the NET_DOI
+parameter, or the HOST_DOI parameter.
+
+NET_DOI - This parameter is used to assign a DOI identifier value to a
+particular IP network address.  All CIPSO labels within datagrams destined
+for the particular IP network MUST use the specified DOI identifier.  All
+CIPSO hosts and gateways MUST support either this parameter, the PORT_DOI
+parameter, or the HOST_DOI parameter.
+
+HOST_DOI - This parameter is used to assign a DOI identifier value to a
+particular IP host address.  All CIPSO labels within datagrams destined for
+the particular IP host will use the specified DOI identifier.  All CIPSO
+hosts and gateways MUST support either this parameter, the PORT_DOI
+parameter, or the NET_DOI parameter.
+
+This list represents the minimal set of configuration parameters required
+to be compliant.  Implementors are encouraged to add to this list to
+provide enhanced functionality and control.  For example, many security
+policies may require both incoming and outgoing datagrams be checked against
+the port and host label ranges.
+
+
+4.1    Port Range Parameters
+
+The labels represented by the PORT_LABEL_MAX and PORT_LABEL_MIN parameters
+MAY be in CIPSO or local format.  Some CIPSO systems, such as routers, may
+want to have the range parameters expressed in CIPSO format so that incoming
+labels do not have to be converted to a local format before being compared
+against the range.  If multiple DOIs are supported by one of these CIPSO

+
+
+systems then multiple port range parameters would be needed, one set for
+each DOI supported on a particular port.
+
+The port range will usually represent the total set of labels that may
+exist on the logical network accessed through the corresponding network
+interface.  It may, however, represent a subset of these labels that are
+allowed to enter the CIPSO system.
+
+
+4.2    Single Label CIPSO Hosts
+
+CIPSO implementations that support only one label are not required to
+support the parameters described above.  These limited implementations are
+only required to support a NET_LABEL parameter.  This parameter contains
+the CIPSO label that may be inserted in datagrams that exit the host.  In
+addition, the host MUST reject any incoming datagram that has a label which
+is not equivalent to the NET_LABEL parameter.
+
+
+5.    Handling Procedures
+
+This section describes the processing requirements for incoming and
+outgoing IP datagrams.  Just providing the correct CIPSO label format
+is not enough.  Assumptions will be made by one system on how a
+receiving system will handle the CIPSO label.  Wrong assumptions may
+lead to non-interoperability or even a security incident.  The
+requirements described below represent the minimal set needed for
+interoperability and that provide users some level of confidence.
+Many other requirements could be added to increase user confidence,
+however at the risk of restricting creativity and limiting vendor
+participation.
+
+
+5.1    Input Procedures
+
+All datagrams received through a network port MUST have a security label
+associated with them, either contained in the datagram or assigned to the
+receiving port.  Without this label the host, gateway, or router will not
+have the information it needs to make security decisions.  This security
+label will be obtained from the CIPSO if the option is present in the
+datagram.  See section 4.1.2 for handling procedures for unlabeled
+datagrams.  This label will be compared against the PORT (if appropriate)
+and HOST configuration parameters defined in section 3.
+
+If any field within the CIPSO option, such as the DOI identifier, is not
+recognized the IP datagram is discarded and an ICMP "parameter problem"
+(type 12) is generated and returned.  The ICMP code field is set to "bad
+parameter" (code 0) and the pointer is set to the start of the CIPSO field
+that is unrecognized.
+
+If the contents of the CIPSO are valid but the security label is
+outside of the configured host or port label range, the datagram is
+discarded and an ICMP "destination unreachable" (type 3) is generated
+and returned.  The code field of the ICMP is set to "communication with
+destination network administratively prohibited" (code 9) or to
+
+
+

+
+
+
+"communication with destination host administratively prohibited"
+(code 10).  The value of the code field used is dependent upon whether
+the originator of the ICMP message is acting as a CIPSO host or a CIPSO
+gateway.  The recipient of the ICMP message MUST be able to handle either
+value.  The same procedure is performed if a CIPSO can not be added to an
+IP packet because it is too large to fit in the IP options area.
+
+If the error is triggered by receipt of an ICMP message, the message
+is discarded and no response is permitted (consistent with general ICMP
+processing rules).
+
+
+5.1.1    Unrecognized tag types
+
+The default condition for any CIPSO implementation is that an
+unrecognized tag type MUST be treated as a "parameter problem" and
+handled as described in section 4.1.  A CIPSO implementation MAY allow
+the system administrator to identify tag types that may safely be
+ignored.  This capability is an allowable enhancement, not a
+requirement.
+
+
+5.1.2    Unlabeled Packets
+
+A network port may be configured to not require a CIPSO label for all
+incoming  datagrams.  For this configuration a CIPSO label must be
+assigned to that network port and associated with all unlabeled IP
+datagrams.  This capability might be used for single level networks or
+networks that have CIPSO and non-CIPSO hosts and the non-CIPSO hosts
+all operate at the same label.
+
+If a CIPSO option is required and none is found, the datagram is
+discarded and an ICMP "parameter problem" (type 12) is generated and
+returned to the originator of the datagram.  The code field of the ICMP
+is set to "option missing" (code 1) and the ICMP pointer is set to 134
+(the value of the option type for the missing CIPSO option).
+
+
+5.2    Output Procedures
+
+A CIPSO option MUST appear only once in a datagram.  Only one tag type
+from the MAC Sensitivity class MAY be included in a CIPSO option.  Given
+the current set of defined tag types, this means that CIPSO labels at
+first will contain only one tag.
+
+All datagrams leaving a CIPSO system MUST meet the following condition:
+
+        PORT_LABEL_MIN <= CIPSO label <= PORT_LABEL_MAX
+
+If this condition is not satisfied the datagram MUST be discarded.
+If the CIPSO system only supports one port, the HOST_LABEL_MIN and the
+HOST_LABEL_MAX parameters MAY be substituted for the PORT parameters in
+the above condition.
+
+The DOI identifier to be used for all outgoing datagrams is configured by
+

+
+
+the administrator.  If port level DOI identifier assignment is used, then
+the PORT_DOI configuration parameter MUST contain the DOI identifier to
+use.  If network level DOI assignment is used, then the NET_DOI parameter
+MUST contain the DOI identifier to use.  And if host level DOI assignment
+is employed, then the HOST_DOI parameter MUST contain the DOI identifier
+to use.  A CIPSO implementation need only support one level of DOI
+assignment.
+
+
+5.3    DOI Processing Requirements
+
+A CIPSO implementation MUST support at least one DOI and SHOULD support
+multiple DOIs.  System and network administrators are cautioned to
+ensure that at least one DOI is common within an IP network to allow for
+broadcasting of IP datagrams.
+
+CIPSO gateways MUST be capable of translating a CIPSO option from one
+DOI to another when forwarding datagrams between networks.  For
+efficiency purposes this capability is only a desired feature for CIPSO
+routers.
+
+
+5.4    Label of ICMP Messages
+
+The CIPSO label to be used on all outgoing ICMP messages MUST be equivalent
+to the label of the datagram that caused the ICMP message.  If the ICMP was
+generated due to a problem associated with the original CIPSO label then the
+following responses are allowed:
+
+  a.  Use the CIPSO label of the original IP datagram
+  b.  Drop the original datagram with no return message generated
+
+In most cases these options will have the same effect.  If you can not
+interpret the label or if it is outside the label range of your host or
+interface then an ICMP message with the same label will probably not be
+able to exit the system.
+
+
+6.    Assignment of DOI Identifier Numbers                                   =
+
+Requests for assignment of a DOI identifier number should be addressed to
+the Internet Assigned Numbers Authority (IANA).

+NetLabel Introduction
+==============================================================================
+Paul Moore, paul.moore@hp.com
+
+August 2, 2006
+
+ * Overview
+
+NetLabel is a mechanism which can be used by kernel security modules to attach
+security attributes to outgoing network packets generated from user space
+applications and read security attributes from incoming network packets.  It
+is composed of three main components, the protocol engines, the communication
+layer, and the kernel security module API.
+
+ * Protocol Engines
+
+The protocol engines are responsible for both applying and retrieving the
+network packet's security attributes.  If any translation between the network
+security attributes and those on the host are required then the protocol
+engine will handle those tasks as well.  Other kernel subsystems should
+refrain from calling the protocol engines directly, instead they should use
+the NetLabel kernel security module API described below.
+
+Detailed information about each NetLabel protocol engine can be found in this
+directory, consult '00-INDEX' for filenames.
+
+ * Communication Layer
+
+The communication layer exists to allow NetLabel configuration and monitoring
+from user space.  The NetLabel communication layer uses a message based
+protocol built on top of the Generic NETLINK transport mechanism.  The exact
+formatting of these NetLabel messages as well as the Generic NETLINK family
+names can be found in the the 'net/netlabel/' directory as comments in the
+header files as well as in 'include/net/netlabel.h'.
+
+ * Security Module API
+
+The purpose of the NetLabel security module API is to provide a protocol
+independent interface to the underlying NetLabel protocol engines.  In addition
+to protocol independence, the security module API is designed to be completely
+LSM independent which should allow multiple LSMs to leverage the same code
+base.
+
+Detailed information about the NetLabel security module API can be found in the
+'include/net/netlabel.h' header file as well as the 'lsm_interface.txt' file
+found in this directory.

+NetLabel Linux Security Module Interface
+==============================================================================
+Paul Moore, paul.moore@hp.com
+
+May 17, 2006
+
+ * Overview
+
+NetLabel is a mechanism which can set and retrieve security attributes from
+network packets.  It is intended to be used by LSM developers who want to make
+use of a common code base for several different packet labeling protocols.
+The NetLabel security module API is defined in 'include/net/netlabel.h' but a
+brief overview is given below.
+
+ * NetLabel Security Attributes
+
+Since NetLabel supports multiple different packet labeling protocols and LSMs
+it uses the concept of security attributes to refer to the packet's security
+labels.  The NetLabel security attributes are defined by the
+'netlbl_lsm_secattr' structure in the NetLabel header file.  Internally the
+NetLabel subsystem converts the security attributes to and from the correct
+low-level packet label depending on the NetLabel build time and run time
+configuration.  It is up to the LSM developer to translate the NetLabel
+security attributes into whatever security identifiers are in use for their
+particular LSM.
+
+ * NetLabel LSM Protocol Operations
+
+These are the functions which allow the LSM developer to manipulate the labels
+on outgoing packets as well as read the labels on incoming packets.  Functions
+exist to operate both on sockets as well as the sk_buffs directly.  These high
+level functions are translated into low level protocol operations based on how
+the administrator has configured the NetLabel subsystem.
+
+ * NetLabel Label Mapping Cache Operations
+
+Depending on the exact configuration, translation between the network packet
+label and the internal LSM security identifier can be time consuming.  The
+NetLabel label mapping cache is a caching mechanism which can be used to
+sidestep much of this overhead once a mapping has been established.  Once the
+LSM has received a packet, used NetLabel to decode it's security attributes,
+and translated the security attributes into a LSM internal identifier the LSM
+can use the NetLabel caching functions to associate the LSM internal
+identifier with the network packet's label.  This means that in the future
+when a incoming packet matches a cached value not only are the internal
+NetLabel translation mechanisms bypassed but the LSM translation mechanisms are
+bypassed as well which should result in a significant reduction in overhead.

From 446fda4f26822b2d42ab3396aafcedf38a9ff2b6 Mon Sep 17 00:00:00 2001
From: Paul Moore <paul.moore@hp.com>
Date: Thu, 3 Aug 2006 16:48:06 -0700
Subject: [NetLabel]: CIPSOv4 engine

Add support for the Commercial IP Security Option (CIPSO) to the IPv4
network stack.  CIPSO has become a de-facto standard for
trusted/labeled networking amongst existing Trusted Operating Systems
such as Trusted Solaris, HP-UX CMW, etc.  This implementation is
designed to be used with the NetLabel subsystem to provide explicit
packet labeling to LSM developers.

The CIPSO/IPv4 packet labeling works by the LSM calling a NetLabel API
function which attaches a CIPSO label (IPv4 option) to a given socket;
this in turn attaches the CIPSO label to every packet leaving the
socket without any extra processing on the outbound side.  On the
inbound side the individual packet's sk_buff is examined through a
call to a NetLabel API function to determine if a CIPSO/IPv4 label is
present and if so the security attributes of the CIPSO label are
returned to the caller of the NetLabel API function.

From d15c345fe3b8dfda0fa5a1d2143a35fffa746a43 Mon Sep 17 00:00:00 2001
From: Paul Moore <paul.moore@hp.com>

Subject: [NetLabel]: core NetLabel subsystem

Add a new kernel subsystem, NetLabel, to provide explicit packet
labeling services (CIPSO, RIPSO, etc.) to LSM developers.  NetLabel is
designed to work in conjunction with a LSM to intercept and decode
security labels on incoming network packets as well as ensure that
outgoing network packets are labeled according to the security
mechanism employed by the LSM.  The NetLabel subsystem is configured
through a Generic NETLINK interface described in the header files
included in this patch.

Subject: [NetLabel]: CIPSOv4 and Unlabeled packet integration

Add CIPSO/IPv4 and unlabeled packet management to the NetLabel
subsystem.  The CIPSO/IPv4 changes allow the configuration of
CIPSO/IPv4 within the overall NetLabel framework.  The unlabeled
packet changes allows NetLabel to pass unlabeled packets without
error.

From 7420ed23a4f77480b5b7b3245e5da30dd24b7575 Mon Sep 17 00:00:00 2001
From: Venkat Yekkirala <vyekkirala@TrustedCS.com>

Subject: [NetLabel]: SELinux support

Add NetLabel support to the SELinux LSM and modify the
socket_post_create() LSM hook to return an error code.  The most
significant part of this patch is the addition of NetLabel hooks into
the following SELinux LSM hooks:

 * selinux_file_permission()
 * selinux_socket_sendmsg()
 * selinux_socket_post_create()
 * selinux_socket_sock_rcv_skb()
 * selinux_socket_getpeersec_stream()
 * selinux_socket_getpeersec_dgram()
 * selinux_sock_graft()
 * selinux_inet_conn_request()

The basic reasoning behind this patch is that outgoing packets are
"NetLabel'd" by labeling their socket and the NetLabel security
attributes are checked via the additional hook in
selinux_socket_sock_rcv_skb().  NetLabel itself is only a labeling
mechanism, similar to filesystem extended attributes, it is up to the
SELinux enforcement mechanism to perform the actual access checks.

In addition to the changes outlined above this patch also includes
some changes to the extended bitmap (ebitmap) and multi-level security
(mls) code to import and export SELinux TE/MLS attributes into and out
of NetLabel.

Subject: [IPV6]: Multiple Routing Tables

Currently all automatically generated routes are put into the
same table. This could be changed at a later point after
considering the produced locking overhead.

From fe4944e59c357f945f81bc67edb7ed1392e875ad Mon Sep 17 00:00:00 2001
From: Thomas Graf <tgraf@suug.ch>
Date: Fri, 4 Aug 2006 23:03:05 -0700
Subject: [NETLINK]: Extend netlink messaging interface

Adds:
 nlmsg_get_pos()                 return current position in message
 nlmsg_trim()                    trim part of message
 nla_reserve_nohdr(skb, len)     reserve room for an attribute w/o hdr
 nla_put_nohdr(skb, len, data)   add attribute w/o hdr
 nla_find_nested()               find attribute in nested attributes

Fixes nlmsg_new() to take allocation flags and consider size.

Subject: [NET]: Convert link modification to new netlink api

Transforms do_setlink() into rtnl_setlink() using the new
netlink api. A warning message printed to the console is
added in the event that a change request fails while part
of the change request has been comitted already. The ioctl()
based nature of net devices makes it almost impossible to
move on to atomic netlink operations without obsoleting
some of the functionality.

Subject: [NET]: Convert link dumping to new netlink api

Transforms netlink code to dump link tables to use the new
netlink api. Makes rtnl_getlink() available regardless of the
availability of the wireless extensions.

Adding copy_rtnl_link_stats() avoids the structural dependency
of struct rtnl_link_stats on struct net_device_stats and thus
avoids troubles later on.

Subject: [NET]: Replace CHECKSUM_HW by CHECKSUM_PARTIAL/CHECKSUM_COMPLETE

Replace CHECKSUM_HW by CHECKSUM_PARTIAL (for outgoing packets, whose
checksum still needs to be completed) and CHECKSUM_COMPLETE (for
incoming packets, device supplied full checksum).

Patch originally from Herbert Xu, updated by myself for 2.6.18-rc3.

Subject: [NEIGH]: Move netlink neighbour bits to linux/neighbour.h

Moves netlink neighbour bits to linux/neighbour.h. Also
moves bits to be exported to userspace from net/neighbour.h
to linux/neighbour.h and removes __KERNEL__ guards, userspace
is not supposed to be using it.

rtnetlink_rcv_msg() is not longer required to parse attributes
for the neighbour layer, remove dependency on obsolete and
buggy rta_buf.

rtnetlink_rcv_msg() is not longer required to parse attributes
for the neighbour tables layer, remove dependency on obsolete and
buggy rta_buf.

- * To retrieve the neighbour tables send RTM_GETNEIGHTBL with the
- * NLM_F_DUMP flag set. Every neighbour table configuration is
- * spread over multiple messages to avoid running into message
- * size limits on systems with many interfaces. The first message
- * in the sequence transports all not device specific data such as
- * statistics, configuration, and the default parameter set.
- * This message is followed by 0..n messages carrying device
- * specific parameter sets.
- * Although the ordering should be sufficient, NDTA_NAME can be
- * used to identify sequences. The initial message can be identified
- * by checking for NDTA_CONFIG. The device specific messages do
- * not contain this TLV but have NDTPA_IFINDEX set to the
- * corresponding interface index.
- *
- * To change neighbour table attributes, send RTM_SETNEIGHTBL
- * with NDTA_NAME set. Changeable attribute include NDTA_THRESH[1-3],
- * NDTA_GC_INTERVAL, and all TLVs in NDTA_PARMS unless marked
- * otherwise. Device specific parameter sets can be changed by
- * setting NDTPA_IFINDEX to the interface index of the corresponding
- * device.

Subject: [NET]: Round out in-kernel sockets API

This patch implements wrapper functions that provide a convenient way
to access the sockets API for in-kernel users like sunrpc, cifs &
ocfs2 etc and any future users.

Subject: [IPV4]: Use network-order dport for all visible inet_lookup_*

Right now most inet_lookup_* functions take a host-order hnum instead
of a network-order dport because that's how it is represented
internally.

This means that users of these functions have to be careful about
using the right byte-order.  To add more confusion, inet_lookup takes
a network-order dport unlike all other functions.

So this patch changes all visible inet_lookup functions to take a
dport and move all dport->hnum conversion inside them.

Subject: [NET]: sock_register interface changes

The sock_register() doesn't change the family, so the protocols can
define it read-only.  No caller ever checks return value from
sock_unregister()

Subject: [NET]: Use u32 for routing table IDs

Use u32 for routing table IDs in net/ipv4 and net/decnet in preparation of
support for a larger number of routing tables. net/ipv6 already uses u32
everywhere and needs no further changes. No functional changes are made by
this patch.

Subject: [NET]: Introduce RTA_TABLE/FRA_TABLE attributes

Introduce RTA_TABLE route attribute and FRA_TABLE routing rule attribute
to hold 32 bit routing table IDs. Usespace compatibility is provided by
continuing to accept and send the rtm_table field, but because of its
limited size it can only carry the low 8 bits of the table ID. This
implies that if larger IDs are used, _all_ userspace programs using them
need to use RTA_TABLE.

Subject: [IPV4]: Increase number of possible routing tables to 2^32

Increase the number of possible routing tables to 2^32 by replacing the
fixed sized array of pointers by a hash table and replacing iterations
over all possible table IDs by hash table walking.

Subject: [HTB]: Use hlist for hash lists.

Use hlist instead of list for the hash list. This saves
space, and we can check for double delete better.

Add code to initialize rb tree nodes, and check for double deletion.
This is not a real fix, but I can make it trap sometimes and may
be a bandaid for: http://bugzilla.kernel.org/show_bug.cgi?id=6681

Subject: [IRDA]: Replace hard-coded dev_self[] array sizes with ARRAY_SIZE()

Several IR drivers used "for (i = 0; i < 4; i++)" to walk their
dev_self[] table.  Better to use ARRAY_SIZE().  And fix ali-ircc so it
won't run off the end if we find too many adapters.

Subject: [NETLINK]: Add notification message sending interface

Adds nlmsg_notify() implementing proper notification logic. The
message is multicasted to all listeners in the group. The
applications the requests orignates from can request a unicast
back report in which case said socket will be excluded from the
multicast to avoid duplicated notifications.

nlmsg_multicast() is extended to take allocation flags to
allow notification in atomic contexts.

Subject: [RTNETLINK]: Add rtnetlink notification interface

Adds rtnl_notify() to send rtnetlink notification messages and
rtnl_set_sk_err() to report notification errors as socket
errors in order to indicate the need of a resync due to loss
of events.

nlmsg_report() is added to properly document the meaning of
NLM_F_ECHO.

Subject: [NET/IPV4/IPV6]: Change some sysctl variables to __read_mostly

Change net/core, ipv4 and ipv6 sysctl variables to __read_mostly.

Couldn't actually measure any performance increase while testing (.3%
I consider noise), but seems like the right thing to do.

Subject: [IPv4]: FIB configuration using struct fib_config

Introduces struct fib_config replacing the ugly struct kern_rta
prone to ordering issues. Avoids creating faked netlink messages
for auto generated routes or requests via ioctl.

A new interface net/nexthop.h is added to help navigate through
nexthop configuration arrays.

A new struct nl_info will be used to carry the necessary netlink
information to be used for notifications later on.

Subject: [PKT_SCHED]: Kill pkt_act.h inlining.

This was simply making templates of functions and mostly causing a lot
of code duplication in the classifier action modules.

We solve this more cleanly by having a common "struct tcf_common" that
hash worker functions contained once in act_api.c can work with.

Callers work with real action objects that have the common struct
plus their module specific struct members.  You go from a common
object to the higher level one using a "to_foo()" macro which makes
use of container_of() to do the dirty work.

This also kills off act_generic.h which was only used by act_simple.c
and keeping it around was more work than the it's value.

Subject: [IPv6] route: Simplify ip6_del_rt()

Provide a simple ip6_del_rt() for the majority of users and
an alternative for the exception via netlink. Avoids code
obfuscation.

Subject: [IPv6] route: Simplify ip6_ins_rt()

Provide a simple ip6_ins_rt() for the majority of users and
an alternative for the exception via netlink. Avoids code
obfuscation.

Subject: [IPv6] route: FIB6 configuration using struct fib6_config

Replaces the struct in6_rtmsg based interface orignating from
the ioctl interface with a struct fib6_config based on. Allows
changing the interface without breaking the ioctl interface
and avoids passing on tons of parameters.

The recently introduced struct nl_info is used to pass on
netlink authorship information for notifications.

Subject: [SCTP]: Extend /proc/net/sctp/snmp to provide more statistics.

This patch adds more statistics info under /proc/net/sctp/snmp
that should be useful for debugging. The additional events that
are counted now include timer expirations, retransmits, packet
and data chunk discards.

The Data chunk discards include all the cases where a data chunk
is discarded including high tsn, bad stream, dup tsn and the most
useful one(out of receive buffer/rwnd).

Also moved the SCTP MIB data structures from the generic include
directories to include/sctp/sctp.h.

From df7deeb5402087ea0387173aaf067d37a264a8f0 Mon Sep 17 00:00:00 2001
From: Vladislav Yasevich <vladislav.yasevich@hp.com>
Date: Tue, 22 Aug 2006 00:19:51 -0700
Subject: [SCTP]: Cleanup nomem handling in the state functions.

This patch cleans up the "nomem" conditions that may occur during the
processing by the state machine functions. In most cases we delay adding
side-effect commands until all memory allocations are done.

Subject: [SCTP]: Fix IPv6 address flag setting when doing peel-off/accept.

During accept/peeloff we try to copy the list of bound addresses from
the original endpoint to the new one. However, we forgot to set the flag
to say that IPv6 is allowed on the new endpoint.

Subject: [NETFILTER]: x_tables: replace IPv4 dscp match by address family
 independent version

This replaces IPv4 dscp match by address family independent version.
This also
	- utilizes dsfield.h to get the DS field in IPv4/IPv6 header, and
	- checks for the DSCP value from user space.
	- fixes Kconfig help text.

Subject: [NETFILTER]: x_tables: replace IPv4 DSCP target by address family
 independent version

This replaces IPv4 DSCP target by address family independent version.
This also
	- utilizes dsfield.h to get/mangle DS field in IPv4/IPv6 header
	- fixes Kconfig help text.

Subject: [SCTP]: Remove multiple levels of msecs to jiffies conversions.

The SCTP sysctl entries are displayed in milliseconds, but stored
internally in jiffies. This results in multiple levels of msecs to
jiffies conversion and as a result produces a truncation error. This
patch makes things consistent in that we store and display defaults
in milliseconds and only convert once for use by association.
This patch also adds some sane min/max values so that we don't go off
the deep end.

From 7e49e6de30efa716614e280d97963c570f3acf29 Mon Sep 17 00:00:00 2001
From: Masahide NAKAMURA <nakam@linux-ipv6.org>
Date: Fri, 22 Sep 2006 15:05:15 -0700
Subject: [XFRM]: Add XFRM_MODE_xxx for future use.

Transformation mode is used as either IPsec transport or tunnel.
It is required to add two more items, route optimization and inbound trigger
for Mobile IPv6.
Based on MIPL2 kernel patch.

This patch was also written by: Ville Nuorvala <vnuorval@tcs.hut.fi>

Subject: [XFRM] STATE: Allow non IPsec protocol.

It will be added two more transformation protocols (routing header
and destination options header) for Mobile IPv6.
xfrm_id_proto_match() can be handle zero as all, IPSEC_PROTO_ANY as
all IPsec and otherwise as exact one.

From: Masahide NAKAMURA <nakam@linux-ipv6.org>
Date: Wed, 23 Aug 2006 17:57:28 -0700
Subject: [XFRM] STATE: Add a hook to find offset to be inserted header in
 outbound.

On current kernel, ip6_find_1stfragopt() is used by IPv6 IPsec to find
offset to be inserted header in outbound for transport mode. (BTW, no
usage may be needed for IPv4 case.)  Mobile IPv6 requires another
logic for routing header and destination options header
respectively. This patch is common platform for the offset and adopts
it to IPsec.

Based on MIPL2 kernel patch.

Subject: [XFRM] STATE: Introduce route optimization mode.

Route optimization is used with routing header and destination options
header for Mobile IPv6.

At outbound it makes header space like IPsec transport. At inbound it
does nothing because exhdrs.c functions have responsibility to update
skbuff information for these headers.

Subject: [XFRM] STATE: Common receive function for route optimization
 extension headers.

XFRM_STATE_WILDRECV flag is introduced; the last resort state is set
it and receives packet which is not route optimized but uses such
extension headers i.e. Mobile IPv6 signaling (binding update and
acknowledgement).  A node enabled Mobile IPv6 adds the state.

Based on MIPL2 kernel patch.

Subject: [XFRM]: Rename secpath_has_tunnel to secpath_has_nontransport.

On current kernel inbound transformation state is allowed transport and
disallowed tunnel mode when mismatch is occurred between tempates and states.
As the result of adding two more modes by Mobile IPv6, this function name
is misleading. Inbound transformation can allow only transport mode
when mismatch is occurred between template and secpath.
Based on MIPL2 kernel patch.

Subject: [XFRM] STATE: Add a hook to obtain local/remote outbound address.

Outbound transformation replaces both source and destination address with
state's end-point addresses at the same time when IPsec tunnel mode.
It is also required to change them for Mobile IPv6 route optimization, but we
should care about the following differences:
 - changing result is not end-point but care-of address
 - either source or destination is replaced for each state
This hook is a common platform to change outbound address.
Based on MIPL2 kernel patch.

Subject: [XFRM] STATE: Support non-fragment outbound transformation headers.

For originated outbound IPv6 packets which will fragment, ip6_append_data()
should know length of extension headers before sending them and
the length is carried by dst_entry.
IPv6 IPsec headers fragment then transformation was
designed to place all headers after fragment header.
OTOH Mobile IPv6 extension headers do not fragment then
it is a good idea to make dst_entry have non-fragment length to tell it
to ip6_append_data().

Subject: [XFRM] IPV6: Update outbound state timestamp for each sending.

With this patch transformation state is updated last used time
for each sending. Xtime is used for it like other state lifetime
expiration.
Mobile IPv6 enabled nodes will want to know traffic status of each
binding (e.g. judgement to request binding refresh by correspondent node,
or to keep home/care-of nonce alive by mobile node).
The last used timestamp is an important hint about it.
Based on MIPL2 kernel patch.

This patch was also written by: Henrik Petander <petander@tcs.hut.fi>

Subject: [XFRM] IPV6: Restrict bundle reusing

For outbound transformation, bundle is checked whether it is
suitable for current flow to be reused or not. In such IPv6 case
as below, transformation may apply incorrect bundle for the flow instead
of creating another bundle:

- The policy selector has destination prefix length < 128
  (Two or more addresses can be matched it)
- Its bundle holds dst entry of default route whose prefix length < 128
  (Previous traffic was used such route as next hop)
- The policy and the bundle were used a transport mode state and
  this time flow address is not matched the bundled state.

This issue is found by Mobile IPv6 usage to protect mobility signaling
by IPsec, but it is not a Mobile IPv6 specific.
This patch adds strict check to xfrm_bundle_ok() for each
state mode and address when prefix length is less than 128.

Subject: [IPV6] MIP6: Add socket option and ancillary data interface of
 routing header type 2.

Add socket option and ancillary data interface of routing header type
2.  Mobile IPv6 application will use this to send binding
acknowledgement with the header without relation of confirmed route
optimization (binding).

Based on MIPL2 kernel patch.

Subject: [IPV6]: Allow to replace skbuff by TLV parser.

In receiving Mobile IPv6 home address option which is a TLV carried by
destination options header, kernel will try to mangle source adderss
of packet. Think of cloned skbuff it is required to replace it by the
parser just like routing header case.

This is a framework to achieve that to allow TLV parser to replace
inbound skbuff pointer.

Subject: [IPV6] MIP6: Revert address to send ICMPv6 error.

IPv6 source address is replaced in receiving packet
with home address option carried by destination options header.
To send ICMPv6 error back, original address which is received one on wire
should be used. This function checks such header is included
and reverts them.
Based on MIPL2 kernel patch.

This patch was also written by: Ville Nuorvala <vnuorval@tcs.hut.fi>

Subject: [IPV6] IPSEC: Support sending with Mobile IPv6 extension headers.

Mobile IPv6 defines home address option as an option of destination
options header. It is placed before fragment header then
ip6_find_1stfragopt() is fixed to know about it.

Home address option also carries final source address of the flow,
then outbound AH calculation should take care of it like routing
header case.  Based on MIPL2 kernel patch.

Like ICMPv6, mobility header is handled through raw socket.
In inbound case, check only whether ICMPv6 error should be sent as a reply
or not by kernel.

Subject: [XFRM]: Trace which secpath state is reject factor.

For Mobile IPv6 usage, it is required to trace which secpath state is
reject factor in order to notify it to user space (to know the address
which cannot be used route optimized communication).

Based on MIPL2 kernel patch.

This patch was also written by: Henrik Petander <petander@tcs.hut.fi>

Subject: [XFRM]: Introduce XFRM_MSG_REPORT.

XFRM_MSG_REPORT is a message as notification of state protocol and
selector from kernel to user-space.

Mobile IPv6 will use it when inbound reject is occurred at route
optimization to make user-space know a binding error requirement.

Based on MIPL2 kernel patch.

Subject: [IPV6] MIP6: Ignore to report if mobility headers is rejected.

Ignore to report user-space for known mobility headers rejected by
destination options header transformation.
Mobile IPv6 specification (RFC3775) says that mobility header
is used with destination options header carrying home address option
only for binding update message. Other type message cannot be used
and node must drop it silently (and must not send binding error) if
receving such packet.
To achieve it, (1) application should use transformation policy and
wild-card states to catch binding update message prior other packets
(2) kernel doesn't report the reject to user-space not to send
binding error message by application.
This patch is for (2).
Based on MIPL2 kernel patch.

This patch was also written by: Ville Nuorvala <vnuorval@tcs.hut.fi>

Subject: [XFRM] POLICY: sub policy support.

Sub policy is introduced. Main and sub policy are applied the same flow.
(Policy that current kernel uses is named as main.)
It is required another transformation policy management to keep IPsec
and Mobile IPv6 lives separate.
Policy which lives shorter time in kernel should be a sub i.e. normally
main is for IPsec and sub is for Mobile IPv6.
(Such usage as two IPsec policies on different database can be used, too.)

Limitation or TODOs:
 - Sub policy is not supported for per socket one (it is always inserted as main).
 - Current kernel makes cached outbound with flowi to skip searching database.
   However this patch makes it disabled only when "two policies are used and
   the first matched one is bypass case" because neither flowi nor bundle
   information knows about transformation template size.

Subject: [XFRM]: Add sorting interface for state and template.

Under two transformation policies it is required to merge them.
This is a platform to sort state for outbound and templates
for inbound respectively.
It will be used when Mobile IPv6 and IPsec are used at the same time.

Subject: [XFRM] IPV6: Add sort functions to combine templates/states for
 IPsec.

Add sort functions to combine templates/states for IPsec.
Think of outbound transformation order we should be careful with transport AH
which must be the last of all transport ones.

Subject: [XFRM]: Dynamic xfrm_state hash table sizing.

The grow algorithm is simple, we grow if:

1) we see a hash chain collision at insert, and
2) we haven't hit the hash size limit (currently 1*1024*1024 slots), and
3) the number of xfrm_state objects is > the current hash mask

All of this needs some tweaking.

Remove __initdata from "hashdist" so we can use it safely at run time.

Subject: [XFRM]: Add generation count to xfrm_state and xfrm_dst.

Each xfrm_state inserted gets a new generation counter
value.  When a bundle is created, the xfrm_dst objects
get the current generation counter of the xfrm_state
they will attach to at dst->xfrm.

xfrm_bundle_ok() will return false if it sees an
xfrm_dst with a generation count different from the
generation count of the xfrm_state that dst points to.

This provides a facility by which to passively and
cheaply invalidate cached IPSEC routes during SA
database changes.

Subject: [XFRM]: Do not flush all bundles on SA insert.

Instead, simply set all potentially aliasing existing xfrm_state
objects to have the current generation counter value.

This will make routes get relooked up the next time an existing
route mentioning these aliased xfrm_state objects gets used,
via xfrm_dst_check().

Subject: [XFRM]: Kill excessive refcounting of xfrm_state objects.

The refcounting done for timers and hash table insertions
are just wasted cycles.  We can eliminate all of this
refcounting because:

1) The implicit refcount when the xfrm_state object is active
   will always be held while the object is in the hash tables.
   We never kfree() the xfrm_state until long after we've made
   sure that it has been unhashed.

2) Timers are even easier.  Once we mark that x->km.state as
   anything other than XFRM_STATE_VALID (__xfrm_state_delete
   sets it to XFRM_STATE_DEAD), any timer that fires will
   do nothing and return without rearming the timer.

   Therefore we can defer the del_timer calls until when the
   object is about to be freed up during GC.  We have to use
   del_timer_sync() and defer it to GC because we can't do
   a del_timer_sync() while holding x->lock which all callers
   of __xfrm_state_delete hold.

This makes SA changes even more light-weight.

Subject: [XFRM]: Hash xfrm_state objects by source address too.

The source address is always non-prefixed so we should use
it to help give entropy to the bydst hash.

From 2518c7c2b3d7f0a6b302b4efe17c911f8dd4049f Mon Sep 17 00:00:00 2001

Subject: [XFRM]: Hash policies when non-prefixed.

This idea is from Alexey Kuznetsov.

It is common for policies to be non-prefixed.  And for
that case we can optimize lookups, insert, etc. quite
a bit.

For each direction, we have a dynamically sized policy
hash table for non-prefixed policies.  We also have a
hash table on policy->index.

For prefixed policies, we have a list per-direction which
we will consult on lookups when a non-prefix hashtable
lookup fails.

This still isn't as efficient as I would like it.  There
are four immediate problems:

1) Lots of excessive refcounting, which can be fixed just
   like xfrm_state was
2) We do 2 hash probes on insert, one to look for dups and
   one to allocate a unique policy->index.  Althought I wonder
   how much this matters since xfrm_state inserts do up to
   3 hash probes and that seems to perform fine.
3) xfrm_policy_insert() is very complex because of the priority
   ordering and entry replacement logic.
4) Lots of counter bumping, in addition to policy refcounts,
   in the form of xfrm_policy_count[].  This is merely used
   to let code path(s) know that some IPSEC rules exist.  So
   this count is indexed per-direction, maybe that is overkill.

Subject: IB/mthca: Fix lid used for sending traps

The SM LID used to send traps to is incorrectly set to port LID.  This
is a regression from 2.6.17 -- after a PortInfo MAD is received, no
traps are sent to the SM LID.  The traps go to the loopback interface
instead, and are dropped there.  The SM LID should be taken from the
sm_lid of the PortInfo response.

The bug was introduced by commit 12bbb2b7be7f5564952ebe0196623e97464b8ac5:

Subject: IB/uverbs: Fix lockdep warning when QP is created with 2 CQs

Lockdep warns when userspace creates a QP that uses different CQs for
send completions and receive completions, because both CQs are locked
and their mutexes belong to the same lock class.  However, we know
that the mutexes are distinct and the nesting is safe (there is no
possibility of AB-BA deadlock because the mutexes are locked with
down_read()), so annotate the situation with SINGLE_DEPTH_NESTING to
get rid of the lockdep warning.

Subject: [IPSEC] esp: Defer output IV initialization to first use.

First of all, if the xfrm_state only gets used for input
packets this entropy is a complete waste.

Secondly, it is often the case that a configuration loads
many rules (perhaps even dynamically) and they don't all
necessarily ever get used.

This get_random_bytes() call was showing up in the profiles
for xfrm_state inserts which is how I noticed this.

Subject: [IPV6] MIP6: Several obvious clean-ups.

- Remove redundant code.  Pointed out by Brian Haley <brian.haley@hp.com>.
- Unify code paths with/without CONFIG_IPV6_MIP.
- Use NIP6_FMT for IPv6 address textual presentation.
- Fold long line.  Pointed out by David Miller <davem@davemloft.net>.

Support masking the nfmark value before the search. The mask value is
global for all filters contained in one instance. It can only be set
when a new instance is created, all filters must specify the same mask.

Fix mark comparison, also dump the mask to userspace when the mask is
zero, but the mark is not (in which case the mark is dumped, so the
mask is needed to make sense of it).

Subject: [NETLINK]: remove third bogus argument from NLA_PUT_FLAG

This patch removes the 'value' argument from NLA_PUT_FLAG which is
unused anyway. The documentation comment was already correct so it
doesn't need an update :)

From: Gerrit Renker <gerrit@erg.abdn.ac.uk>
Date: Sat, 26 Aug 2006 20:06:05 -0700
Subject: [UDP]: Unify UDPv4 and UDPv6 ->get_port()

This patch creates one common function which is called by
udp_v4_get_port() and udp_v6_get_port(). As a result,
  * duplicated code is removed
  * udp_port_rover and local port lookup can now be removed from udp.h
  * further savings follow since the same function will be used by UDP-Litev4
    and UDP-Litev6

In contrast to the patch sent in response to Yoshifujis comments
(fixed by this variant), the code below also removes the
EXPORT_SYMBOL(udp_port_rover), since udp_port_rover can now remain
local to net/ipv4/udp.c.

Subject: [NETLINK]: Improve string attribute validation

Introduces a new attribute type NLA_NUL_STRING to support NUL
terminated strings. Attributes of this kind require to carry
a terminating NUL within the maximum specified in the policy.

The `old' NLA_STRING which is not required to be NUL terminated
is extended to provide means to specify a maximum length of the
string.

Aims at easing the pain with using nla_strlcpy() on temporary
buffers.

Subject: [NETFILTER] bridge: simplify nf_bridge_pad

Do some simple optimization on the nf_bridge_pad() function
and don't use magic constants. Eliminate a double call and
the #ifdef'd code for CONFIG_BRIDGE_NETFILTER.

Subject: [NETFILTER] bridge: debug message fixes

If CONFIG_NETFILTER_DEBUG is enabled, it shouldn't change the
actions of the filtering. The message about skb->dst being NULL
is commonly triggered by dhclient, so it is useless. Make sure all
messages end in newline.

Subject: [DCCP]: Tidyup CCID3 list handling

As Arnaldo Carvalho de Melo points out I should be using list_entry in case
the structure changes in future. Current code functions but is reliant
on position and requires type cast.

Noticed when doing this that I have one more variable than I needed so
removing that also.

Subject: [TCP]: Fix rcv mss estimate for LRO

By passing a Linux-generated TSO packet straight back into Linux, Xen
becomes our first LRO user :) Unfortunately, there is at least one spot
in our stack that needs to be changed to cope with this.

The receive MSS estimate is computed from the raw packet size.  This is
broken if the packet is GSO/LRO.  Fortunately the real MSS can be found
in gso_size so we simply need to use that if it is non-zero.

Real LRO NICs should of course set the gso_size field in future.

this and similar issues in the future, use rcu for sk->sk_filter field read

Subject: [IPSEC]: output mode to take an xfrm state as input param

Expose IPSEC modes output path to take an xfrm state as input param.
This makes it consistent with the input mode processing (which already
takes the xfrm state as a param).

Subject: [XFRM]: remove xerr_idxp from __xfrm_policy_check()

It seems that during the MIPv6 respin, some code which was originally
conditionally compiled around CONFIG_XFRM_ADVANCED was accidently left
in after the config option was removed.

This patch removes an extraneous pointer (xerr_idxp) which is no
longer needed.

Subject: [NETFILTER]: Change tunables to __read_mostly

Change some netfilter tunables to __read_mostly.  Also fixed some
incorrect file reference comments while I was in there.

(this will be my last __read_mostly patch unless someone points out
something else that needs it)

Subject: [IPV6] address: Support NLM_F_EXCL when adding addresses

iproute2 doesn't provide the NLM_F_CREATE flag when adding addresses,
it is assumed to be implied. The existing code issues a check on
said flag when the modify operation fails (likely due to ENOENT)
before continueing to create it, this leads to a hard to predict
result, therefore the NLM_F_CREATE check is removed.

Subject: [SCTP]: Cleanups

This patch contains the following cleanups:
- make the following needlessly global function static:
  - socket.c: sctp_apply_peer_addr_params()
- add proper prototypes for the several global functions in
  include/net/sctp/sctp.h

Note that this fixes wrong prototypes for the following functions:
- sctp_snmp_proc_exit()
- sctp_eps_proc_exit()
- sctp_assocs_proc_exit()

The latter was spotted by the GNU C compiler and reported
by David Woodhouse.

Subject: [TCP]: Send ACKs each 2nd received segment.

It does not affect either mss-sized connections (obviously) or
connections controlled by Nagle (because there is only one small
segment in flight).

The idea is to record the fact that a small segment arrives on a
connection, where one small segment has already been received and
still not-ACKed. In this case ACK is forced after tcp_recvmsg() drains
receive buffer.

In other words, it is a "soft" each-2nd-segment ACK, which is enough
to preserve ACK clock even when ABC is enabled.

Subject: [XFRM]: Fix wildcard as tunnel source

Hashing SAs by source address breaks templates with wildcards as tunnel
source since the source address used for hashing/lookup is still 0/0.
Move source address lookup to xfrm_tmpl_resolve_one() so we can use the
real address in the lookup.

Subject: [DCCP] ACKVEC: fix ackvector length calculation

Fix ackvector length calculation upon receiving an "ack-of-ack".  This
patch avoids the ackvector from growing too large which causes it to
not be inserted into packets.

Subject: [DCCP] ackvec: Fix how DCCP_ACKVEC_STATE_NOT_RECEIVED is used

Fix the way state is masked out.  DCCP_ACKVEC_STATE_NOT_RECEIVED is
defined as appears in the packet, therefore bit shifting is not
required.  This fix allows CCID2 to correctly detect losses.

Subject: [DCCP] CCID2: Tell DCCP to quickly check whether cwnd is available

If not enough cwnd is available, tell the sender to check again as
soon as possible.  This will increase CPU utilization (polling
frequently for cwnd) but will improve network performance.  That is,
the sender will need to wait less before detecting the increase of
cwnd.  A better architecture would be for the CCID to call-back (or
dequeue) from DCCP when it is able to transmit traffic -- not the
other way around as it currently occurs.

Subject: [DCCP] CCID2: Allocate seq records on demand

Allocate more sequence state on demand.  Each time a packet is sent
out by CCID2, a record of it needs to be kept.  This list of records
grows proportionally to cwnd.  Previously, the length of this list was
hardcored and therefore the cwnd could only grow to this value (of
128).  Now, records are allocated on demand as necessary---cwnd may
grow as it wishes.  The exceptional case of when memory is not
available is not handled gracefully.  Perhaps, cwnd should be capped
at that point.

Subject: [DCCP] CCID2: Halve cwnd once upon multiple losses in a single RTT

When multiple losses occur in one RTT, the window should be halved
only once [a single "congestion event"].  This is now implemented,
although not perfectly.  Slightly changed the interface for changing
the cwnd: pass hctx instead of dp.  This is required in order to allow
for change_cwnd to be called from _init().

Subject: [DCCP] CCID2: Add helper functions for changing important CCID2 state

Introduce methods which manipulate interesting congestion control
state such as pipe and rtt estimate.  This is useful for people
wishing to monitor the variables of CCID and instrument the code
[perhaps using Kprobes].  Personally, I am a fan of
encapsulation---that justifies this change =D.

Subject: [IPV4]: ipip and ip_gre encapsulation bugs

Handling of ipip and ip_gre ICMP error relaying is b0rken; it accesses
8bit field + 3 reserved octets as host-endian 32bit, does comparison,
subtraction and stuffs the result back.  That breaks on big-endian.

Fixed, made endian-clean.

[ Note that this effected code is permanently commented out with
  and ifdef, so this error couldn't actually cause problems for
  anyone. -DaveM ]

From 50b9f1d509eb998db73cd769c9511186474f566e Mon Sep 17 00:00:00 2001
From: Patrick McHardy <kaber@trash.net>
Date: Wed, 20 Sep 2006 11:58:17 -0700
Subject: [NETFILTER]: xt_conntrack: clean up overly long lines

Also fix some whitespace errors and use the NAT bits instead of deriving
the state manually.

Subject: [NETFILTER]: ctnetlink: simplify the code to dump the conntrack table

Merge the bits to dump the conntrack table and the ones to dump and
zero counters in a single piece of code. This patch does not change
the default behaviour if accounting is not enabled.

Subject: [NETFILTER]: conntrack: fix race condition in early_drop

On SMP environments the maximum number of conntracks can be overpassed
under heavy stress situations due to an existing race condition.

        CPU A                   CPU B
     atomic_read()               ...
     early_drop()                ...
        ...                  atomic_read()
   allocate conntrack      allocate conntrack
     atomic_inc()             atomic_inc()

This patch moves the counter incrementation before the early drop stage.

Subject: [NETFILTER]: x_tables: simplify compat API

Split the xt_compat_match/xt_compat_target into smaller type-safe functions
performing just one operation. Handle all alignment and size-related
conversions centrally in these function instead of requiring each module to
implement a full-blown conversion function. Replace ->compat callback by
->compat_from_user and ->compat_to_user callbacks, responsible for
converting just a single private structure.

size check was disabled because of this.

Subject: [NETFILTER]: PPTP conntrack: fix GRE keymap leak

When destroying the GRE expectations without having seen the GRE connection
the keymap entry is not freed, leading to a memory leak and, in case of
a following call within the same session, failure during expectation setup.

Subject: [NETFILTER]: PPTP conntrack: fix another GRE keymap leak

When the master PPTP connection times out while still having unfullfilled
expectations (and a GRE keymap entry) associated with it, the keymap entry
is not destroyed.

Add a destroy callback to struct ip_conntrack_helper and use it to destroy
PPTP siblings when the master is destroyed.

Subject: [IPV6] NDISC: Handle NDP messages to proxied addresses.

It is required to respond to NDP messages sent directly to the "target"
unicast address.  Proxying node (router) is required to handle such
messages.  To achieve this, check if the packet in forwarding patch is
NDP message.

With this patch, the proxy neighbor entries are always looked up in
forwarding path.  We may want to optimize further.

Based on MIPL2 kernel patch.

Subject: [IPV6]: Don't forward packets to proxied link-local address.

Proxying router can't forward traffic sent to link-local address, so signal
the sender and discard the packet. This behavior is clarified by Mobile IPv6
specification (RFC3775) but might be required for all proxying router.
Based on MIPL2 kernel patch.

Subject: [IPV6] NDISC: Avoid updating neighbor cache for proxied address in
 receiving NA.

This aims at proxying router not updating neighbor cache entry for proxied
address when it receives NA because either the proxied node is off link or
it has already sent a NA to the proxied router.

Subject: [IPV6] NDISC: Set per-entry is_router flag in Proxy NA.

We have sent NA with router flag from the node-wide forwarding
configuration.  This is not appropriate for proxy NA, and it should be
set according to each proxy entry's configuration.

This is used by Mobile IPv6 home agent to support physical home link
in acting as a proxy router for mobile node which is not a router,
for example.

Subject: [IPV6] NDISC: Fix is_router flag setting.

We did not send appropriate IsRouter flag if the forwarding setting is
positive even value.  Let's give 1/0 value to ndisc_send_na().

Also, existing users of ndisc_send_na() give 0/1 to override,
we can omit redundant operation in that function.

Bug hinted by Nicolas Dichtel <nicolas.dichtel@6wind.com>.

Subject: [IPV6] ADDRCONF: Allow non-DAD'able addresses.

IFA_F_NODAD flag, similar to IN6_IFF_NODAD in BSDs, is introduced
to skip DAD.

This flag should be set to Mobile IPv6 Home Address(es) on Mobile
Node because DAD would fail if we should perform DAD; our Home Agent
protects our Home Address(es).

Subject: [IPV6] ADDRCONF: Mobile IPv6 Home Address support.

IFA_F_HOMEADDRESS is introduced for Mobile IPv6 Home Addresses on
Mobile Node.

The IFA_F_HOMEADDRESS flag should be set for Mobile IPv6 Home
Addresses for 2 purposes. 1) We need to check this on receipt of
Type 2 Routing Header (RFC3775 Secion 6.4), 2) We prefer Home
Address(es) in source address selection (RFC3484 Section 5 Rule 4).

Subject: IB/uverbs: Allow resize CQ operation to return driver-specific data

Add a ib_uverbs_resize_cq_resp.driver_data field so that low-level
drivers can return data from a resize CQ operation to userspace.  Have
ib_uverbs_resize_cq() only copy the cqe field, to avoid having to bump
the userspace ABI.

Subject: IB/uverbs: Pass userspace data to modify_srq and modify_qp methods

Pass a struct ib_udata to the low-level driver's ->modify_srq() and
->modify_qp() methods, so that it can get to the device-specific data
passed in by the userspace driver.

From 373d9915803aebbbf7fd3841efd9dac31c32e148 Mon Sep 17 00:00:00 2001
From: Ralph Campbell <ralph.campbell@qlogic.com>

Subject: IB/ipath: Performance improvements via mmap of queues

Improve performance of userspace post receive, post SRQ receive, and
poll CQ operations for ipath by allowing userspace to directly mmap()
receive queues and completion queues.  This eliminates the copying
between userspace and the kernel in the data path.

- * Quick description of our CQ/QP locking scheme:
- *
- * We have one global lock that protects dev->cq/qp_table.  Each
- * struct ipath_cq/qp also has its own lock.  An individual qp lock
- * may be taken inside of an individual cq lock.  Both cqs attached to
- * a qp may be locked, with the send cq locked first.  No other
- * nesting should be done.
- *
- * Each struct ipath_cq/qp also has an atomic_t ref count.  The
- * pointer from the cq/qp_table to the struct counts as one reference.
- * This reference also is good for access through the consumer API, so
- * modifying the CQ/QP etc doesn't need to take another reference.
- * Access because of a completion being polled does need a reference.
- *
- * Finally, each struct ipath_cq/qp has a wait_queue_head_t for the
- * destroy function to sleep on.
- *
- * This means that access from the consumer API requires nothing but
- * taking the struct's lock.
- *
- * Access because of a completion event should go as follows:
- * - lock cq/qp_table and look up struct
- * - increment ref count in struct
- * - drop cq/qp_table lock
- * - lock struct, do your thing, and unlock struct

Subject: IB/ipath: More changes to support InfiniPath on PowerPC 970 systems

Ordering of writethrough store buffers needs to be forced, and we need
to use ifdef to get writethrough behavior to InfiniPath buffers, because
there is no generic way to specify that at this time (similar to code
in char/drm/drm_vm.c and block/z2ram.c).

Change comment: no longer imply that user can set ipath_kpiobufs to zero.
Actually set ipath_kpiobufs from parameter. Previously only altered
per-device ipath_lastport_piobuf, which was over-written in chip init.

From 34b2aafea38efdf02cd8107a6e1057e2a297c447 Mon Sep 17 00:00:00 2001
From: Bryan O'Sullivan <bos@pathscale.com>
Date: Fri, 25 Aug 2006 11:24:32 -0700
Subject: IB/ipath: simplify layering code

A lot of ipath layer code was only called in one place. Now that the
ipath_core and ib_ipath drivers are merged, it's more sensible to simply
inline the simple stuff that the layer code was doing.

From 0fd41363e0785247b7c19127318abc8b5eacc86b Mon Sep 17 00:00:00 2001
From: Bryan O'Sullivan <bos@pathscale.com>
Date: Fri, 25 Aug 2006 11:24:34 -0700
Subject: IB/ipath: remove stale references to userspace SMA

When we first submitted a userspace subnet management agent, it was
rejected, so we left it out of the final driver submission.  This patch
removes a number of vestigial references to it.

From: Bryan O'Sullivan <bos@pathscale.com>
Date: Fri, 25 Aug 2006 11:24:40 -0700
Subject: IB/ipath: add serial number to hardware freeze error message

Also added the word "Hardware" after "Fatal" to make it more obvious
that it's hardware, not software.

Subject: IB/mad: Add support for dual-sided RMPP transfers.

The implementation assumes that any RMPP request that requires a
response uses DS RMPP.  Based on the RMPP start-up scenarios defined
by the spec, this should be a valid assumption.  That is, there is no
start-up scenario defined where an RMPP request is followed by a
non-RMPP response.  By having this assumption we avoid any API
changes.

In order for a node that supports DS RMPP to communicate with one that
does not, RMPP responses assume a new window size of 1 if a DS ACK has
not been received.  (By DS ACK, I'm referring to the turn-around ACK
after the final ACK of the request.)  This is a slight spec deviation,
but is necessary to allow communication with nodes that do not
generate the DS ACK.  It also handles the case when a response is sent
after the request state has been discarded.

Subject: IB/mad: Remove unused includes

The ib_mad module does not use a kthread function, but mad_priv.h
includes <linux/kthread.h>.  mad_rmpp.c does not do any DMA-related
stuff, but includes <linux/dma-mapping.h>.  Remove the unused includes.

From 922a8e9fb2e0711212badce47a41137e2ca04cb3 Mon Sep 17 00:00:00 2001
From: Tom Tucker <tom@opengridcomputing.com>
Date: Thu, 3 Aug 2006 16:02:40 -0500
Subject: RDMA: iWARP Connection Manager.

Add an iWARP Connection Manager (CM), which abstracts connection
management for iWARP devices (RNICs).  It is a logical instance of the
xx_cm where xx is the transport type (ib or iw).  The symbols exported
are used by the transport independent rdma_cm module, and are
available also for transport dependent ULPs.

+ * The following services provide a mechanism for pre-allocating iwcm_work
+ * elements.  The design pre-allocates them  based on the cm_id type:
+ *	LISTENING IDS: 	Get enough elements preallocated to handle the
+ *			listen backlog.
+ *	ACTIVE IDS:	4: CONNECT_REPLY, ESTABLISHED, DISCONNECT, CLOSE
+ *	PASSIVE IDS:	3: ESTABLISHED, DISCONNECT, CLOSE
+ *
+ * Allocating them in connect and listen avoids having to deal
+ * with allocation failures on the event upcall from the provider (which
+ * is called in the interrupt context).
+ *
+ * One exception is when creating the cm_id for incoming connection requests.
+ * There are two cases:
+ * 1) in the event upcall, cm_event_handler(), for a listening cm_id.  If
+ *    the backlog is exceeded, then no more connection request events will
+ *    be processed.  cm_event_handler() returns -ENOMEM in this case.  Its up
+ *    to the provider to reject the connectino request.
+ * 2) in the connection request workqueue handler, cm_conn_req_handler().
+ *    If work elements cannot be allocated for the new connect request cm_id,
+ *    then IWCM will call the provider reject method.  This is ok since
+ *    cm_conn_req_handler() runs in the workqueue thread context.

From 07ebafbaaa72aa6a35472879008f5a1d1d469a0c Mon Sep 17 00:00:00 2001
From: Tom Tucker <tom@opengridcomputing.com>
Date: Thu, 3 Aug 2006 16:02:42 -0500
Subject: RDMA: iWARP Core Changes.

Modifications to the existing rdma header files, core files, drivers,
and ulp files to support iWARP, including:
 - Hook iWARP CM into the build system and use it in rdma_cm.
 - Convert enum ib_node_type to enum rdma_node_type, which includes
   the possibility of RDMA_NODE_RNIC, and update everything for this.

+ * Verbs Request Objects:
+ *
+ * VQ Request Objects are allocated by the kernel verbs handlers.
+ * They contain a wait object, a refcnt, an atomic bool indicating that the
+ * adapter has replied, and a copy of the verb reply work request.
+ * A pointer to the VQ Request Object is passed down in the context
+ * field of the work request message, and reflected back by the adapter
+ * in the verbs reply message.  The function handle_vq() in the interrupt
+ * path will use this pointer to:
+ * 	1) append a copy of the verbs reply message
+ * 	2) mark that the reply is ready
+ * 	3) wake up the kernel verbs handler blocked awaiting the reply.
+ *
+ *
+ * The kernel verbs handlers do a "get" to put a 2nd reference on the
+ * VQ Request object.  If the kernel verbs handler exits before the adapter
+ * can respond, this extra reference will keep the VQ Request object around
+ * until the adapter's reply can be processed.  The reason we need this is
+ * because a pointer to this object is stuffed into the context field of
+ * the verbs work request message, and reflected back in the reply message.
+ * It is used in the interrupt handler (handle_vq()) to wake up the appropriate
+ * kernel verb handler that is blocked awaiting the verb reply.
+ * So handle_vq() will do a "put" on the object when it's done accessing it.
+ * NOTE:  If we guarantee that the kernel verb handler will never bail before
+ *        getting the reply, then we don't need these refcnts.
+ *
+ *
+ * VQ Request objects are freed by the kernel verbs handlers only
+ * after the verb has been processed, or when the adapter fails and
+ * does not reply.
+ *
+ *
+ * Verbs Reply Buffers:
+ *
+ * VQ Reply bufs are local host memory copies of a
+ * outstanding Verb Request reply
+ * message.  The are always allocated by the kernel verbs handlers, and _may_ be
+ * freed by either the kernel verbs handler -or- the interrupt handler.  The
+ * kernel verbs handler _must_ free the repbuf, then free the vq request object
+ * in that order.

Subject: RDMA/cma: Protect against adding device during destruction

Closes a window where address resolution can attach an rdma_cm_id to a
device during destruction of the rdma_cm_id.  This can result in the
rdma_cm_id remaining in the device list after its memory has been
freed.

Subject: IB/iser: fix a check of SG alignment for RDMA

dma mapping may include a "compaction" of the sg associated with scsi command.
Hence, the size of the maximal prefix of the SG which is aligned for rdma must be
compared against the length of the dma mapped sg (mem->dma_nents) and not against
the size of it before it was mapped (mem->size).

Subject: IB/iser: Limit the max size of a scsi command

Currently, the data length of a command coming down from scsi-ml
is limited only by the size of its sg list (sg_tablesize). The
max data length may be different for different page size values.
By setting max_sectors, we limit the data length to
max_sectors*512 bytes.

Subject: IB/iser: make FMR "page size" be 4K and not PAGE_SIZE

As iser is able to use at most one rdma operation for the
execution of a scsi command, and registration of the sg
associated with scsi command has its restrictions, the code
checks if an sg is "aligned for rdma".

Alignment for rdma is measured in "fmr page" units whose
possible resolutions are different between HCAs and can be
smaller, equal or bigger to the system page size.

When the system page size is bigger than 4KB (eg the default
with ia64 kernels) there a bigger chance that an sg would be
aligned for rdma if the fmr page size is 4KB.

Change the code to create FMR whose pages are of size 4KB
and to take that into account when processing the sg.

Subject: IB/iser: Do not use FMR for a single dma entry sg

Fast Memory Registration (fmr) is used to register for rdma an sg whose
elements are not linearly sequential after dma mapping.

The IB verbs layer provides an "all dma memory MR (memory region)" which
can be used for RDMA-ing a dma linearly sequential buffer.

Change the code to use the dma mr instead of doing fmr when dma mapping
produces a single dma entry sg.

Subject: IPoIB: Refactor completion handling

Split up ipoib_ib_handle_wc() into ipoib_ib_handle_rx_wc() and
ipoib_ib_handle_tx_wc() to make the code easier to read.  This will
also help implement NAPI in the future.

Require users to register with SA module, to prevent the sa_query
module text from going away while an SA query callback is still
running.  Update all in-tree users for the new interface.

Subject: IB/mthca: Recover from catastrophic errors

Trigger device remove and then add when a catastrophic error is
detected in hardware.  This, in turn, will cause a device reset, which
we hope will recover from the catastrophic condition.

Since this might interefere with debugging the root cause, add a
module option to suppress this behaviour.

Subject: IB/mthca: Simplify calls to mthca_cq_clean()

If a QP has separate send and receive CQs, then the send CQ will never
have receive completions from that QP in it.  So when cleaning the
send CQ, there's no need to pass in an SRQ pointer, even if the QP is
attached to an SRQ.

Subject: IPoIB: Create MCGs with all attributes required by RFC

RFC 4391 ("Transmission of IP over InfiniBand (IPoIB)") says:

  If the IB multicast group does not already exist, one must be
  created first with the IPoIB link MTU.  The MGID MUST use the same
  P_Key, Q_Key, SL, MTU, and HopLimit as those used in the
  broadcast-GID.  The rest of attributes SHOULD follow the values used
  in the broadcast-GID as well.

However, the current IPoIB driver is only setting the attributes
required by the InfiniBand spec to create a multicast group, so in
particular the MTU and HopLimit are not being set.  Add these
attributes when creating MCGs, and also set the Rate attribute, since
IPoIB pays attention to that attribute as well.

Subject: IPoIB: Rejoin all multicast groups after a port event

When ipoib_ib_dev_flush() is called because of a port event, the
driver needs to rejoin all multicast groups, since the flush will call
ipoib_mcast_dev_flush() (via ipoib_ib_dev_down()).  Otherwise no
(non-broadcast) multicast groups will be rejoined until the networking
core calls ->set_multicast_list again, and so multicast reception will
be broken for potentially a long time.

Subject: [CPUFREQ] Fix some more CPU hotplug locking.

Lukewarm IQ detected in hotplug locking

[<b0102c81>] sysenter_past_esp+0x56/0x79

As there are other places that call cpufreq_update_policy without
the hotplug lock, it seems better to keep the hotplug locking
at the lower level for the time being until this is revamped.

Subject: [PATCH] mv643xx_eth: restrict to 32-bit PPC_MULTIPLATFORM

No 64-bit PPC_MULTIPLATFORM platforms use the mv643xx_eth driver,
so build it only on PPC32.

Subject: [NET] GT96100: Delete bitrotting ethernet driver

Code for the EV96100 evaluation board hasn't compiled since at least
November 15, 2003, so it is being deleted as of 2.6.18 due to lack of
a user base.

Subject: [PATCH] Spidernet: add ethtool -S (show statistics)

Add the ethtool -S (show statistics) feature to the Spidernet ethernet
driver.  I have tested it extensively and believe it is ready to be
applied.

Subject: [PATCH] fix ancient breakage in ebus_init()

Back when pci_dev had base_address[], loop of form
	base = &...->base_address[0];
	for (.....) {
		...
		*base++ = addr;
	}
was fine, but when that array got spread in ->resource[...].start
replacing the initialization with
	base = &...->resource[0].start;
was not a sufficient modification.  IOW this code got broken for cases
when there had been more than one resource to fill.  All way back in
2.3.41-pre3...

Subject: [PATCH] sun4: fix sbus_setup_iommu()

iommu_init() and iounit_init() are never called for sun4, but that's not
enough - these calls should be ifdefed out since the functions in question
simply do not exist for CONFIG_SUN4 kernel.

Subject: NFS: Add a new ACCESS rpc call cache to the linux nfs client

The current access cache only allows one entry at a time to be cached for each
inode. Add a per-inode red-black tree in order to allow more than one to
be cached at a time.

Should significantly cut down the time spent in path traversal for shared
directories such as ${PATH}, /usr/share, etc.

Subject: NFS: Add an ACCESS cache memory shrinker

A pinned inode may in theory end up filling memory with cached ACCESS
calls. This patch ensures that the VM may shrink away the cache in these
particular cases.
The shrinker works by iterating through the list of inodes on the global
nfs_access_lru_list, and removing the least recently used access
cache entry until it is done (or until the entire cache is empty).

From: David Howells <dhowells@redhat.com>

Subject: NFS: Add dentry materialisation op

The attached patch adds a new directory cache management function that prepares
a disconnected anonymous function to be connected into the dentry tree. The
anonymous dentry is transferred the name and parentage from another dentry.

The following changes were made in [try #2]:

 (*) d_materialise_dentry() now switches the parentage of the two nodes around
     correctly when one or other of them is self-referential.

The following changes were made in [try #7]:

 (*) d_instantiate_unique() has had the interior part split out as function
     __d_instantiate_unique(). Callers of this latter function must be holding
     the appropriate locks.

 (*) _d_rehash() has been added as a wrapper around __d_rehash() to call it
     with the most obvious hash list (the one from the name). d_rehash() now
     calls _d_rehash().

 (*) d_materialise_dentry() is now __d_materialise_dentry() and is static.

 (*) d_materialise_unique() added to perform the combination of d_find_alias(),
     d_materialise_dentry() and d_add_unique() that the NFS client was doing
     twice, all within a single dcache_lock critical section. This reduces the
     number of times two different spinlocks were being accessed.

The following further changes were made:

 (*) Add the dentries onto their parents d_subdirs lists.

Subject: NFS: Fix up split of fs/nfs/inode.c

Fix ups for the splitting of the superblock stuff out of fs/nfs/inode.c,
including:

 (*) Move the callback tcpport module param into callback.c.

 (*) Move the idmap cache timeout module param into idmap.c.

 (*) Changes to internal.h:

     (*) namespace-nfs4.c was renamed to nfs4namespace.c.

     (*) nfs_stat_to_errno() is in nfs2xdr.c, not nfs4xdr.c.

     (*) nfs4xdr.c is contingent on CONFIG_NFS_V4.

     (*) nfs4_path() is only uses if CONFIG_NFS_V4 is set.

Plus also:

 (*) The sec_flavours[] table should really be const.

Make the nfs_callback_up()/down() prototypes just do nothing if NFS4 is not
enabled.  Also make the down function void type since we can't really do
anything if it fails.

Subject: NFS: Rename nfs_server::nfs4_state

Rename nfs_server::nfs4_state to nfs_client as it will be used to represent the
client state for NFS2 and NFS3 also.

Subject: NFS: Add a lookupfh NFS RPC op

Add a lookup filehandle NFS RPC op so that a file handle can be looked up
without requiring dentries and inodes and other VFS stuff when doing an NFS4
pathwalk during mounting.

Subject: NFS: Generalise the nfs_client structure

Generalise the nfs_client structure by:

 (1) Moving nfs_client to a more general place (nfs_fs_sb.h).

 (2) Renaming its maintenance routines to be non-NFS4 specific.

 (3) Move those maintenance routines to a new non-NFS4 specific file (client.c)
     and move the declarations to internal.h.

 (4) Make nfs_find/get_client() take a full sockaddr_in to include the port
     number (will be required for NFS2/3).

 (5) Make nfs_find/get_client() take the NFS protocol version (again will be
     required to differentiate NFS2, 3 & 4 client records).

Also:

 (6) Make nfs_client construction proceed akin to inodes, marking them as under
     construction and providing a function to indicate completion.

 (7) Make nfs_get_client() wait interruptibly if it finds a client that it can
     share, but that client is currently being constructed.

 (8) Make nfs4_create_client() use (6) and (7) instead of locking cl_sem.

From 0c7d90cfed91a283228017ba6faf37ee0bcd32b1 Mon Sep 17 00:00:00 2001
From: David Howells <dhowells@redhat.com>
Date: Tue, 22 Aug 2006 20:06:10 -0400
Subject: NFS: Use the dentry superblock directly in nfs_statfs()

Use the nominated dentry's superblock directly in the NFS statfs() op to get a
file handle, rather than using s_root (which will become a dummy dentry in a
future patch).

From 5006a76cca8f86c6975c16fcf67e83b8b0eee2b6 Mon Sep 17 00:00:00 2001
From: David Howells <dhowells@redhat.com>
Date: Tue, 22 Aug 2006 20:06:12 -0400
Subject: NFS: Eliminate client_sys in favour of cl_rpcclient

Eliminate nfs_server::client_sys in favour of nfs_client::cl_rpcclient as we
only really need one per server that we're talking to since it doesn't have any
security on it.

The retransmission management variables are also moved to the common struct as
they're required to set up the cl_rpcclient connection.

The NFS2/3 client and client_acl connections are thenceforth derived by cloning
the cl_rpcclient connection and post-applying the authorisation flavour.

The code for setting up the initial common connection has been moved to
client.c as nfs_create_rpc_client().  All the NFS program definition tables are
also moved there as that's where they're now required rather than super.c.

Subject: NFS: Start rpciod in server common management

Start rpciod in the server common (nfs_client struct) management code rather
than in the superblock management code.  This means we only need to "start" it
once per server instead of once per superblock.

Subject: NFS: Share NFS superblocks per-protocol per-server per-FSID

The attached patch makes NFS share superblocks between mounts from the same
server and FSID over the same protocol.

It does this by creating each superblock with a false root and returning the
real root dentry in the vfsmount presented by get_sb(). The root dentry set
starts off as an anonymous dentry if we don't already have the dentry for its
inode, otherwise it simply returns the dentry we already have.

We may thus end up with several trees of dentries in the superblock, and if at
some later point one of anonymous tree roots is discovered by normal filesystem
activity to be located in another tree within the superblock, the anonymous
root is named and materialises attached to the second tree at the appropriate
point.

Why do it this way? Why not pass an extra argument to the mount() syscall to
indicate the subpath and then pathwalk from the server root to the desired
directory? You can't guarantee this will work for two reasons:

 (1) The root and intervening nodes may not be accessible to the client.

     With NFS2 and NFS3, for instance, mountd is called on the server to get
     the filehandle for the tip of a path. mountd won't give us handles for
     anything we don't have permission to access, and so we can't set up NFS
     inodes for such nodes, and so can't easily set up dentries (we'd have to
     have ghost inodes or something).

     With this patch we don't actually create dentries until we get handles
     from the server that we can use to set up their inodes, and we don't
     actually bind them into the tree until we know for sure where they go.

 (2) Inaccessible symbolic links.

     If we're asked to mount two exports from the server, eg:

	mount warthog:/warthog/aaa/xxx /mmm
	mount warthog:/warthog/bbb/yyy /nnn

     We may not be able to access anything nearer the root than xxx and yyy,
     but we may find out later that /mmm/www/yyy, say, is actually the same
     directory as the one mounted on /nnn. What we might then find out, for
     example, is that /warthog/bbb was actually a symbolic link to
     /warthog/aaa/xxx/www, but we can't actually determine that by talking to
     the server until /warthog is made available by NFS.

     This would lead to having constructed an errneous dentry tree which we
     can't easily fix. We can end up with a dentry marked as a directory when
     it should actually be a symlink, or we could end up with an apparently
     hardlinked directory.

     With this patch we need not make assumptions about the type of a dentry
     for which we can't retrieve information, nor need we assume we know its
     place in the grand scheme of things until we actually see that place.

This patch reduces the possibility of aliasing in the inode and page caches for
inodes that may be accessed by more than one NFS export. It also reduces the
number of superblocks required for NFS where there are many NFS exports being
used from a server (home directory server + autofs for example).

This in turn makes it simpler to do local caching of network filesystems, as it
can then be guaranteed that there won't be links from multiple inodes in
separate superblocks to the same cache file.

Obviously, cache aliasing between different levels of NFS protocol could still
be a problem, but at least that gives us another key to use when indexing the
cache.

This patch makes the following changes:

 (1) The server record construction/destruction has been abstracted out into
     its own set of functions to make things easier to get right.  These have
     been moved into fs/nfs/client.c.

     All the code in fs/nfs/client.c has to do with the management of
     connections to servers, and doesn't touch superblocks in any way; the
     remaining code in fs/nfs/super.c has to do with VFS superblock management.

 (2) The sequence of events undertaken by NFS mount is now reordered:

     (a) A volume representation (struct nfs_server) is allocated.

     (b) A server representation (struct nfs_client) is acquired.  This may be
     	 allocated or shared, and is keyed on server address, port and NFS
     	 version.

     (c) If allocated, the client representation is initialised.  The state
     	 member variable of nfs_client is used to prevent a race during
     	 initialisation from two mounts.

     (d) For NFS4 a simple pathwalk is performed, walking from FH to FH to find
     	 the root filehandle for the mount (fs/nfs/getroot.c).  For NFS2/3 we
     	 are given the root FH in advance.

     (e) The volume FSID is probed for on the root FH.

     (f) The volume representation is initialised from the FSINFO record
     	 retrieved on the root FH.

     (g) sget() is called to acquire a superblock.  This may be allocated or
     	 shared, keyed on client pointer and FSID.

     (h) If allocated, the superblock is initialised.

     (i) If the superblock is shared, then the new nfs_server record is
     	 discarded.

     (j) The root dentry for this mount is looked up from the root FH.

     (k) The root dentry for this mount is assigned to the vfsmount.

 (3) nfs_readdir_lookup() creates dentries for each of the entries readdir()
     returns; this function now attaches disconnected trees from alternate
     roots that happen to be discovered attached to a directory being read (in
     the same way nfs_lookup() is made to do for lookup ops).

     The new d_materialise_unique() function is now used to do this, thus
     permitting the whole thing to be done under one set of locks, and thus
     avoiding any race between mount and lookup operations on the same
     directory.

 (4) The client management code uses a new debug facility: NFSDBG_CLIENT which
     is set by echoing 1024 to /proc/net/sunrpc/nfs_debug.

 (5) Clone mounts are now called xdev mounts.

 (6) Use the dentry passed to the statfs() op as the handle for retrieving fs
     statistics rather than the root dentry of the superblock (which is now a
     dummy).

Subject: NFS: Add server and volume lists to /proc

Make two new proc files available:

	/proc/fs/nfsfs/servers
	/proc/fs/nfsfs/volumes

The first lists the servers with which we are currently dealing (struct
nfs_client), and the second lists the volumes we have on those servers (struct
nfs_server).

Invoke security_d_instantiate() on root dentries after allocating them with
dentry_alloc_anon().  Normally dentry_alloc_root() would do that, but we don't
call that as we don't want to assign a name to the root dentry at this point
(we may discover the real name later).

Subject: SUNRPC: Create a helper to tell whether a transport is bound

Hide the contents and format of xprt->addr by eliminating direct uses
of the xprt->addr.sin_port field.  This change is required to support
alternate RPC host address formats (eg IPv6).

Test-plan:
Destructive testing (unplugging the network temporarily).  Repeated runs of
Connectathon locking suite with UDP and TCP.

Subject: SUNRPC: Make RPC portmapper use per-transport storage

Move connection and bind state that was maintained in the rpc_clnt
structure to the rpc_xprt structure.  This will allow the creation of
a clean API for plugging in different types of bind mechanisms.

This brings improvements such as the elimination of a single spin lock to
control serialization for all in-kernel RPC binding.  A set of per-xprt
bitops is used to serialize tasks during RPC binding, just like it now
works for making RPC transport connections.

Test-plan:
Destructive testing (unplugging the network temporarily).  Connectathon
with UDP and TCP.  NFSv2/3 and NFSv4 mounting should be carefully checked.
Probably need to rig a server where certain services aren't running, or
that returns an error for some typical operation.

From bbf7c1dd2ae2b4040b41b1065ee9b1b6905b1605 Mon Sep 17 00:00:00 2001
From: Chuck Lever <chuck.lever@oracle.com>
Date: Tue, 22 Aug 2006 20:06:16 -0400
Subject: SUNRPC: Introduce transport switch callout for pluggable rpcbind

Introduce a clean transport switch API for plugging in different types of
rpcbind mechanisms.  For instance, rpcbind can cleanly replace the
existing portmapper client, or a transport can choose to implement RPC
binding any way it likes.

Test plan:
Destructive testing (unplugging the network temporarily).  Connectathon
with UDP and TCP.  NFSv2/3 and NFSv4 mounting should be carefully checked.
Probably need to rig a server where certain services aren't running, or
that returns an error for some typical operation.

Subject: SUNRPC: Create API for displaying remote peer address

Provide an API for formatting the remote peer address for printing without
exposing its internal structure.  The address could be dynamic, so we
support a function call to get the address rather than reading it straight
out of a structure.

Test-plan:
Destructive testing (unplugging the network temporarily).  Probably need
to rig a server where certain services aren't running, or that returns an
error for some typical operation.

Subject: SUNRPC: Use "sockaddr_storage" for storing RPC client's remote peer
 address

IPv6 addresses are big (128 bytes).  Now that no RPC client consumers treat
the addr field in rpc_xprt structs as an opaque, and access it only via the
API calls, we can safely widen the field in the rpc_xprt struct to
accomodate larger addresses.

Test plan:
Compile kernel with CONFIG_NFS enabled.

Subject: SUNRPC: use sockaddr + size when creating remote transport endpoints

Prepare for more generic transport endpoint handling needed by transports
that might use different forms of addressing, such as IPv6.

Introduce a single function call to replace the two-call
xprt_create_proto/rpc_create_client API.  Define a new rpc_create_args
structure that allows callers to pass in remote endpoint addresses of
varying length.

Test-plan:
Compile kernel with CONFIG_NFS enabled.

Subject: LOCKD: Convert to use new rpc_create() API

Replace xprt_create_proto/rpc_create_client with new rpc_create()
interface in the Network Lock Manager.

Note that the semantics of NLM transports is now "hard" instead of "soft"
to provide a better guarantee that lock requests will get to the server.

Test plan:
Repeated runs of Connectathon locking suite.  Check network trace to ensure
NLM requests are working correctly.

Subject: SUNRPC: Eliminate xprt_create_proto and rpc_create_client

The two function call API for creating a new RPC client is now obsolete.
Remove it.

Also, remove an unnecessary check to see whether the caller is capable of
using privileged network services.  The kernel RPC client always uses a
privileged ephemeral port by default; callers are responsible for checking
the authority of users to make use of any RPC service, or for specifying
that a nonprivileged port is acceptable.

Test plan:
Repeated runs of Connectathon locking suite.  Check network trace to ensure
correctness of NLM requests and replies.

Subject: SUNRPC: export new RPC client functions with _GPL

This patch is optional.

It has been suggested that the RPC client internal functions used by upper
layer protocols (such as NFS) be exported via EXPORT_SYMBOL_GPL.  This
patch does that.

Test plan:
Compile kernel with CONFIG_NFS enabled as a module.

Subject: NFS: remove a no-longer-needed error check in nfs_symlink()

In the early days of NFS, there was no duplicate reply cache on the server.
Thus retransmitted non-idempotent requests often found that the request had
already completed on the server.  To avoid passing an unanticipated return
code to unsuspecting applications, NFS clients would often shunt error
codes that implied the request had been retried but already completed.

Thanks to NFS over TCP, duplicate reply caches on the server, and network
performance and reliability improvements, it is safe to remove such checks.

Test plan:
None.

Subject: NFS: Fix double d_drop in nfs_instantiate() error path

If the LOOKUP or GETATTR in nfs_instantiate fail, nfs_instantiate will do a
d_drop before returning.  But some callers already do a d_drop in the case
of an error return.  Make certain we do only one d_drop in all error paths.

This issue was introduced because over time, the symlink proc API diverged
slightly from the create/mkdir/mknod proc API.  To prevent other coding
mistakes of this type, change the symlink proc API to be more like
create/mkdir/mknod and move the nfs_instantiate call into the symlink proc
routines so it is used in exactly the same way for create, mkdir, mknod,
and symlink.

Test plan:
Connectathon, all versions of NFS.

Currently the NFS client does not cache symlinks it creates.  They get
cached only when the NFS client reads them back from the server.

Copy the symlink into the page cache before sending it.

Subject: NFS: NFS_ROOT should use the new rpc_create API

Teach NFS_ROOT to use the new rpc_create API instead of the old two-call
API for creating an RPC transport.

Test plan:
Compile the kernel with the NFS client build-in, and set CONFIG_NFS_ROOT.

Subject: SUNRPC: Add refcounting to the struct rpc_xprt

In a subsequent patch, this will allow the portmapper to take a reference
to the rpc_xprt for which it is updating the port number, fixing an Oops.

Subject: NFS: nfs_lookup - don't hash dentry when optimising away the lookup

If the open intents tell us that a given lookup is going to result in a,
exclusive create, we currently optimize away the lookup call itself. The
reason is that the lookup would not be atomic with the create RPC call, so
why do it in the first place?

A problem occurs, however, if the VFS aborts the exclusive create operation
after the lookup, but before the call to create the file/directory: in this
case we will end up with a hashed negative dentry in the dcache that has
never been looked up.
Fix this by only actually hashing the dentry once the create operation has
been successfully completed.

Subject: NFS: Make read() return an ESTALE if the file has been deleted

Currently, a read() request will return EIO even if the file has been
deleted on the server, simply because that is what the VM will return
if the call to readpage() fails to update the page.

Ensure that readpage() marks the inode as stale if it receives an ESTALE.
Then return that error to userland.

Subject: NFSv4: When mounting with a port=0 argument, substitute port=2049

RFC3530 states that the registered port 2049 for the NFS protocol should be
the default configuration in order to allow clients not to use the RPC
binding protocols.
If the mount program sends us a port=0, we therefore substitute port=2049.

Subject: NFSv4: rpc_mkpipe creating socket inodes w/out sk buffers

This patch stop rpc_mkpipe from create S_IFSOCK nodes what don't
have associated sk buffers attached (which causes SELinux to oops
during NFSv4 mounts). Instead the S_IFIFO mode bit is set which
probably make more sense and seems to work just fine during
my connectathon and fsx testing...

From c461482c8072bb073e6146db320d3da85cdc89ad Mon Sep 17 00:00:00 2001
From: Takashi Iwai <tiwai@suse.de>
Date: Fri, 23 Jun 2006 14:38:23 +0200
Subject: [ALSA] Unregister device files at disconnection

Orignally proposed by Sam Revitch <sam.revitch@gmail.com>.
Unregister device files at disconnection to avoid the futher accesses.
Also, the dev_unregister callback is removed and replaced with the
combination of disconnect + free.
A new function snd_card_free_when_closed() is introduced, which is
used in USB disconnect callback.

Subject: [ALSA] Add experimental support of aggressive AC97 power-saving mode

Added CONFIG_SND_AC97_POWER_SAVE kernel config to enable the support
of aggressive AC97 power-saving mode.  In this mode, the AC97
powerdown register bits are dynamically controlled at each open/close
of PCM streams.
The mode is activated via power_save option for snd-ac97-codec
driver.  As default it's off.  It can be turned on/off on the fly
via sysfs, too.

From 8aa9b586e42099817163aba01d925c2660c4dbbe Mon Sep 17 00:00:00 2001
From: Jaroslav Kysela <perex@suse.cz>
Date: Wed, 5 Jul 2006 17:34:51 +0200
Subject: [ALSA] Control API - more robust TLV implementation

- added callback option
- added READ/WRITE/COMMAND flags to access member
- added WRITE/COMMAND ioctls
- added SNDRV_CTL_EVENT_MASK_TLV for TLV change notifications
- added TLV support to ELEM_ADD ioctl

- Added model=arima for Arima W820Di1 with ALC882 codec chip
- Added EAPD-control verbs to TCL S700 init verbs
- Added missing model strings for Realtek codecs (to be specified
  via module option explicitly for testing/debugging)

Subject: [ALSA] Don't set up the same PID twice in
 snd_hda_multi_out_analog_prepare

Check the hp_nid whether it's identical with front pin to avoid
the setup of the same widget node twice.

Subject: [ALSA] Fix noisy output with shared channel mode with hd-audio

- Fix the wrong initialization of num_dacs when changing the channel
  mode between 2 and multi-channel modes.  It must be evaluated
  after calling snd_hda_ch_mode_put()
- Added the similar check of num_dacs fix in Realtek code.

Subject: [ALSA] hda: sigmatel 9205 family support

Adds support for the '9205 family' which includes some other
part numbers but 9205 is the first one. These are 4 channel
codecs, some have digital mic capability. Support for the digital
mic feature will come later.

Subject: [ALSA] es18xx - Add PnP BIOS support

This patch adds PnP BIOS support to es18xx driver. It allows ESS ES18xx sound
chips integrated in some notebooks (such as DTK FortisPro TOP-5A) that don't
appear as ISA cards (they aren't recognized by ISA PnP, only by PnP BIOS)
to 'just work' automatically.

Subject: [ALSA] Fix control/status mmap with shared PCM substream

The flag to avoid 32bit-incompatible mmap for control/status records
should be outside the pcm substream instance since a substream can be
shared among multiple opens.  Now it's flagged in pcm_file list that
is directly assigned to file->private_data.
Also, removed snd_pcm_add_file() and remove_file() functions and
substream.files field that are not really used in the code.

Subject: [ALSA] Fix substream selection in PCM and rawmidi

The PCM and rawmidi substreams can be selected explicitly by opening
control handle and set via *_PREFER_SUBDEVICE ioctl.  But, when
multiple controls are opened, the driver gets confused.
The patch fixes the initialization of prefer_*_subdevice and the
check of multiple controls.  The first set subdevice is picked up
as the valid one.

Subject: [ALSA] hda-intel - Switch to polling mode for CORB/RIRB communication

Automatically switch to polling mode for CORB/RIRB communication
if the irq-driven mode seems not working well.  If the polling
mode still doesn't work, switch to single_cmd mode as fallback.

Subject: [ALSA] sparc dbri: ring buffered version

It is a complete rework of low level layer to work on ring
buffers for comands and data descriptors. This removes annoying
noise due to delay in data buffer switching.

 Since the DBRI can run in parallel with the CPU, several means of
-synchronization present themselves.  The method implemented here is close
-to the original scheme (Rudolf's), and uses 2 counters (wait_send and
-wait_ackd) to synchronize the command buffer between the CPU and the DBRI.
+synchronization present themselves. The method implemented here is only
+to use the dbri_cmdwait() to wait for execution of batch of sent commands.
 
-A more sophisticated scheme might involve a circular command buffer
-or an array of command buffers.  A routine could fill one with
-commands and link it onto a list.  When a interrupt signaled
-completion of the current command buffer, look on the list for
-the next one.
+A circular command buffer is used here. A new command is being added 
+while other can be executed. The scheme works by adding two WAIT commands
+after each sent batch of commands. When the next batch is prepared it is
+added after the WAIT commands then the WAITs are replaced with single JUMP
+command to the new batch. The the DBRI is forced to reread the last WAIT 
+command (replaced by the JUMP by then). If the DBRI is still executing 
+previous commands the request to reread the WAIT command is ignored.
 
 Every time a routine wants to write commands to the DBRI, it must
-first call dbri_cmdlock() and get an initial pointer into dbri->dma->cmd
-in return. dbri_cmdlock() will block if the previous commands have not
-been completed yet. After this the commands can be written to the buffer,
-and dbri_cmdsend() is called with the final pointer value to send them
-to the DBRI.

Subject: [ALSA] sparc dbri: hardware constrains added

This patch adds ALSA hardware constrains so stereo is possible
only with 16-bit format. It contains small cleanups to ring
buffered code as well.

Subject: [ALSA] intel_hda: MSI support

Simple patch to enable Message Signalled Interrupts for the HDA Intel
audio controller.  Tested with:
 Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03)
MSI is better because it means audio doesn't end up sharing IRQ with USB.

Subject: [ALSA] hda-codec - Support for SigmaTel 9872

- AR11M and AR11S uses the same chip hence we claim to support the AR Series.
- Added commentary about STAC9225s which shares the same id as CXD9872RD.
- Added entry for 7662 but won't work automatically until pci_subdevice
  is known.
- 'vaio' model now corresponds to CXD9872RD_VAIO for backward compat.
- Replaced STAC766x_VAIO with CXD9872RD_VAIO, STAC9872AK_VAIO, STAC9872K_VAIO
  and CXD9872AKD_VAIO
- Added 'vaio-ar' model for potential future modifications.

Subject: [ALSA] hda-codec - restore HDA sigmatel pin configs on resume

This patch restores the Intel HDA Sigmatel codec pin configuration on
resume.  Most of it is dedicated to saving the BIOS pin configuration
if necessary, so that even unrecognized chips can be resumed correctly.

Subject: [ALSA] hda-codec - Fix mic capture with generic parser

Fixed the mic capture with generic parser of hda-codec driver
- Use VREF80 for mic pins if available
- Handle multiple inputs correctly on audio-input widget node.
Confirmed on a conexant codec chip.

Subject: [ALSA] Fix volume control for the AK4358 DAC

Fix volume control for the AK4358 DAC.
The attenuation control registers of the AK4358 use only 7bit for the
volume, the msb is used to enable attenuation output.  Without this
patch there are 256 volume levels the lower 128 of which are mute.

Subject: [ALSA] Support for non-standard rates in USB audio driver

There's at least one USB audio chipset out there which supports only one
non-standard rate (ID 0e6a:0310 supports 46875Hz). There's a few other
patches for this card which are unsatisfactory because they attempt to
map this rate to 44.1k leading to sound distortion.
The patch below uses SNDRV_PCM_RATE_KNOT to properly support the
non-standard rates where they are available.

- Clean up the code in AK4xxx-ADDA i2c code.
- Fix capture gain controls for AK5365
- Changed the static table for DAC/ADC mixer labels to use
  structs
- Implemented TLV entries for each AK codec
  The volumes in AK4524, AK4528 and AK5365 are corrected with
  a table to be suitable for dB conversion.

Subject: [ALSA] hda-intel - Remove volatile

Removed volatile from the position buffer pointer.
Also, use synchronize_irq() instead of unreliable msleep(1)
in the driver remove callback.

Subject: [ALSA] [PPC,SOUND] Fix audio gpio state detection

When booting with line out or headphone plugged, you won't hear anything.
The problem is that after reset all channels are muted, but the actual
value of the gpio port doesn't exactly match the active_val settings as
expected by check_audio_gpio.  For example, the line_mute port is set to
7, but check_audio_gpio would expect 0xd or 0xf, thus its return value
indicates that it is not active, even though it is.  AFAICS only looking
at the low bit is enough to determine whether the port is active.

Subject: [ALSA] ac97: Fix AD1819 volume range

AD1819 volume registers can hold extra bits which do not affect the
actual volume. Add a res_table to the codec patch to fix the problem.
PCM, line and mic volume were tested.

Subject: [ALSA] hdsp - Fix auto-updating of firmware

Fixed the auto-updating of firmware if the breakout box was switched
off/on.  The firmware binary itself was already cached but it wasn't
loaded properly.  Also, request_firmware() is issued if the box was
with firmware at module loading time but later it's erased.
The auto-update is triggered at each PCM action (open, prepare, etc)
and at opening proc files.

Subject: [ALSA] hda-codec - Add independent headphone volume control

This patch addes the support of the independent 'Headphone' volume
control to the generic codec parser.  Some codecs (e.g. Conexant)
have separate connections to the headphone and the independent amp
adjustment is needed.

Subject: [ALSA] Add pcm_class attribute to PCM sysfs entry

This patch adds a new attribute, pcm_class, to each PCM sysfs entry.
It's useful to detect what kind of PCM stream is, for example, HAL
can check whether it's a modem or not.

Subject: [ALSA] hda-intel - Fix pci_disable_msi() call

Fix the order to call pci_disable_msi() to be after free_irq().
(Otherwise pci_disable_msi() bugs you.)
Also, added a description of disable_msi option to documentation.

Subject: [ALSA] hda-codec - Fix SPDIF device number of ALC codecs

Assign the SPDIF always to the secondary device (dev#1) to keep
the same configuration.  Move the optional capture device to the
third device (dev#2).
hda_intel now just ignores the NULL entries in the pcm arrays
from codecs.

Subject: [ALSA] ak4xxx - Remove bogus IPGA controls

Remove IPGA volume controls and merge the IPGA range to ADC volume
controls.  These two volumes are not really independent but connected
simply in different ranges 0-0x7f and 0x80-max.  It doesn't make sense
to provide two controls.
Since both 0x7f and 0x80 specify 0dB, a hack is needed for IPGA range
to skip 0x80 (increment one) for such controls.

Subject: [ALSA] aoa: add locking to tas codec

Looks like I completely forgot to do this. This patch adds locking to
the tas codec so two userspace programs can't hit the controls at the
same time. Tested on my powerbook, but I obviously can't find any
problems even without it since it doesn't do SMP.

Subject: [ALSA] hda_intel prefer 24bit instead of 20bit

If I understand the hda_intel code, for format > 20bit it only advertise
the SNDRV_PCM_FMTBIT_S32_LE format and play it at 32 bit, 20 bit or 24 bit.
But if the 20bit and 24bit are available, actually it prefer the 20bit
format. This path is to prefer the 24bit format instead of 20bit.

From eb06ed8f4c2440558ebf465e8baeac6367d90201 Mon Sep 17 00:00:00 2001

Subject: [ALSA] hda-codec - Support multiple headphone pins

Some machines have multiple headpohne pins (usually on the lpatop
and on the docking station) while the current hda-codec driver
assumes a single headphone pin.  Now it supports multiple hp pins
(at least for detection).
The sigmatel 92xx code supports this new multiple hp pins.
It detects all hp pins for auto-muting, too.
Also, the driver checks speaker pins in addition.  In some cases,
all line-out, speaker and hp-pins coexist.

Subject: [ALSA] hda-codec - Fix mic input with STAC92xx codecs

Fixed mic input with STAC92xx codecs.  The mic pin was sometimes set to
OUTPUT by the headphone jack detection.
Also, try to assign a secondary mic as front-mic (or vice versa)
in the auto-detection if possible.

Fix this driver not to use a static two element host array instead use
a list.  This should fix panic on multiple eject reinsert of the

Subject: [CRYPTO] hmac: Fix hmac_init update call

The crypto_hash_update call in hmac_init gave the number 1
instead of the length of the sg list in bytes.  This is a
missed conversion from the digest => hash change.

As tcrypt only tests crypto_hash_digest it didn't catch this.

From 231839102b54512ced7d3ee7fc9b8bcf5e3b583b Mon Sep 17 00:00:00 2001
From: Douglas Gilbert <dougg@torque.net>
Date: Sat, 16 Sep 2006 20:30:47 -0400
Subject: [SCSI] scsi_debug version 1.80

See http://www.torque.net/sg/sdebug26.html for more
information on the scsi_debug driver.

ChangeLog:
  - add 'vpd_use_hostno' parameter to allow simulated hosts
    to see the same set of targets (and luns). For testing
    multipath software.
  - add 'fake_rw' parameter to ignore the data in READ and
    WRITE commands
  - add support for log subpages (new in SPC-4)
  - yield appropriate block descriptor for MODE SENSE
    commands (only for pdt=0 (i.e. disks))
  - REQUEST SENSE response no longer shows the stopped
    power condition (SAT changed to agree with SPC-3)

Subject: [SCSI] aic7xxx: avoid checking SBLKCTL register for certain cards

For cards that don't support LVD, checking the SBLKCTL register to
determine the bus singalling doesn't work.  So, check that the card
supports LVD first (AHC_ULTRA2) before checking the register.

Subject: [SCSI] aic7xxx: pause sequencer before touching SBLKCTL

Some cards need to pause the sequencer before the SBLKCTL register is
touched.  This fixes a PCI related oops seen on powerpc macs with this
card caused by trying to ascertain the bus signalling before beginning
domain validation.

Subject: [SCSI] zfcp: create private slab caches to guarantee proper data
 alignment

Create private slab caches in order to guarantee proper alignment of
data structures that get passed to hardware.

Sidenote: with this patch slab cache debugging will finally work on s390
(at least no known problems left).

Furthermore this patch does some minor cleanups:
- store ptr for transport template in struct zfcp_data

Subject: [SCSI] zfcp: fix: use correct req_id in eh_abort_handler

zfcp's eh_abort_handler used the wrong request ID to
identify the request to be aborted. The bug was introduced
with commit fea9d6c7bcd8ff1d60ff74f27ba483b3820b18a3
for improved management of request IDs. The bug is
fixed with this patch.

Subject: [SCSI] zfcp: fix: avoid removal of fsf reqs before qdio queues are
 down

Fix the fix ... One of my previous fixes introduced removal of all fsf
requests in zfcp's eh_host_reset_handler. But this must not happen
before qdio queues are shut down. So, I revert the changes of
zfcp_scsi_eh_host_reset_handler.

Subject: [SCSI] aacraid: expose physical devices

Received from Mark Salyzyn:

I am placing this functionality into an insmod parameter. Normally the physical
components are exported to sg, and are blocked from showing up in sd.

Note that the pass-through I/O path via the driver through the Firmware to the
physical disks is not an optimized path, the card is designed for Hardware
RAID, elevator sorting and caching. This should not be used as a means for
utilizing the aacraid based controllers as a generic scsi/SATA/SAS controller,
performance should suck by a few percentage points, any RAID meta-data on the
drives will confuse the controller about who owns the drives and there is a
high risk of destroying content in both directions. Unreliable and for
experimentation or strange controlled circumstances only.

Subject: [SCSI] aacraid: merge rx and rkt code

Received from Mark Salyzyn:

The only real difference between the rkt and rx platform modules is the
offset of the message registers. This patch recognizes this similarity
and simplifies the driver to reduce it's code footprint and to improve
maintainability by reducing the code duplication.

Visibly, the 'rkt.c' portion of this patch looks more complicated than
it really is. View it as retaining the rkt-only specifics of the
interface.

Subject: [SCSI] aacraid: remove scsi_remove_device

Received from Mark Salyzyn:

Until the system is stabilized, I am suggesting the enclosed
modification to prevent the driver from tickling the panic. Once sysfs
and friends are stabilized, the patch may be backed out. We have yet to
evaluate if we really want to relinquish existing Scsi Devices in any
case, holding on to them as configuration of arrays comes and goes makes
some sense as well. As a result, we have opted to pull the lines rather
than comment them in legacy.

Subject: [SCSI] aacraid: README update

Received from Mark Salyzyn:

This patch to the driver's documentation adds a few new product entries,
sorts the entries on OEM lines first for easy searching, followed by
product id order to make it easier to compare against the open source
pci list. The driver has 'family match' so is somewhat future proof, no
code changes are required to recognize the new products.

Subject: [SCSI] eata_pio cleanup and PCI fix

This started as a PCI reference fixup but to do that I need to build it,
to build it I need to fix it and its full of 32bitisms and uglies.

It has been resurrected, I'm not sure if this is a thank you for the
work on the license stuff or punishment for some unknown misdeed however
8). I've also fixed a memory scribble in the init code.

One oddity - the changes from HZ * to constants are deliberate. Whoever
originally wrote the code (or cleaned it up) used HZ for a cycle timing
loop even though is not HZ related. I've put it back to the counts used
in the old days when the driver was most used.

Subject: [SPARC64]: Fix sched_clock() wrapping every ~17 seconds.

Unfortunately, sparc64 doesn't have an easy way to do a "64 X 64 -->
128" bit multiply like PowerPC and IA64 do.  We were doing a
"64 X 64 --> 64" bit multiple which causes overflow very quickly with
a 30-bit quotient shift.

So use a quotientshift count of 10 instead of 30, just like x86 and
ARM do.

This also fixes the wrapping of printk timestamp values every ~17
seconds.

Subject: [SCSI] SPI transport class: misc DV fixes

Key more of the domain validation settings off the inquiry data from
the disk (in particular, don't try IU or DT unless the disk claims to
support them.

Also add a new dv_in_progress flag to prevent recursive DV.

An AST can be delivered via the network after a lock has been removed, so no
need to print an error when we see that.

Subject: ocfs2: Allow binary names in the DLM

The OCFS2 DLM uses strlen() to determine lock name length, which excludes
the possibility of putting binary values in the name string. Fix this by
requiring that string length be passed in as a parameter.

Subject: ocfs2: Update dlmfs for new dlmlock() API

We just need to add a namelen field to the user_lock_res structure, and
update a few debug prints. Instead of updating all debug prints, I took the
opportunity to remove a few that are likely unnecessary these days.

Subject: ocfs2: Update dlmglue for new dlmlock() API

File system lock names are very regular right now, so we really only need to
pass an extra parameter to dlmlock().

Subject: ocfs2: Add new cluster lock type

Replace the dentry vote mechanism with a cluster lock which covers a set
of dentries. This allows us to force d_delete() only on nodes which actually
care about an unlink.

Every node that does a ->lookup() gets a read only lock on the dentry, until
an unlink during which the unlinking node, will request an exclusive lock,
forcing the other nodes who care about that dentry to d_delete() it. The
effect is that we retain a very lightweight ->d_revalidate(), and at the
same time get to make large improvements to the average case performance of
the ocfs2 unlink and rename operations.

This patch adds the cluster lock type which OCFS2 can attach to
dentries.  A small number of fs/ocfs2/dcache.c functions are stubbed
out so that this change can compile.

Subject: ocfs2: Add dentry tracking API

Replace the dentry vote mechanism with a cluster lock which covers a set
of dentries. This allows us to force d_delete() only on nodes which actually
care about an unlink.

Every node that does a ->lookup() gets a read only lock on the dentry, until
an unlink during which the unlinking node, will request an exclusive lock,
forcing the other nodes who care about that dentry to d_delete() it. The
effect is that we retain a very lightweight ->d_revalidate(), and at the
same time get to make large improvements to the average case performance of
the ocfs2 unlink and rename operations.

This patch adds the higher level API and the dentry manipulation code.

From 349457ccf2592c14bdf13b6706170ae2e94931b1 Mon Sep 17 00:00:00 2001
From: Mark Fasheh <mark.fasheh@oracle.com>
Date: Fri, 8 Sep 2006 14:22:21 -0700
Subject: [PATCH] Allow file systems to manually d_move() inside of ->rename()

Some file systems want to manually d_move() the dentries involved in a
rename.  We can do this by making use of the FS_ODD_RENAME flag if we just
have nfs_rename() unconditionally do the d_move().  While there, we rename
the flag to be more descriptive.

OCFS2 uses this to protect that part of the rename operation with a cluster
lock.

Subject: ocfs2: manually d_move() during ocfs2_rename()

Make use of FS_RENAME_DOES_D_MOVE to avoid a race condition that can occur
during ->rename() if we d_move() outside of the parent directory cluster
locks, and another node discovers the new name (created during the rename)
and unlinks it. d_move() will unconditionally rehash a dentry - which will
leave stale data in the system.

Subject: ocfs2: Remove special casing for inode creation in
 ocfs2_dentry_attach_lock()

We can't use LKM_LOCAL for new dentry locks because an unlink and subsequent
re-create of a name/inode pair may result in the lock still being mastered
somewhere in the cluster.

Subject: ocfs2: Free up some space in the lvb

lvb_version doesn't need to be a whole 32 bits. Make it an 8 bit field to
free up some space. This should be backwards compatible until we use one of
the fields, in which case we'd bump the lvb version anyway.

Subject: ocfs2: Remove i_generation from inode lock names

OCFS2 puts inode meta data in the "lock value block" provided by the DLM.
Typically, i_generation is encoded in the lock name so that a deleted inode
on and a new one in the same block don't share the same lvb.

Unfortunately, that scheme means that the read in ocfs2_read_locked_inode()
is potentially thrown away as soon as the meta data lock is taken - we
cannot encode the lock name without first knowing i_generation, which
requires a disk read.

This patch encodes i_generation in the inode meta data lvb, and removes the
value from the inode meta data lock name. This way, the read can be covered
by a lock, and at the same time we can distinguish between an up to date and
a stale LVB.

This will help cold-cache stat(2) performance in particular.

Since this patch changes the protocol version, we take the opportunity to do
a minor re-organization of two of the LVB fields.

From f625c9793b6cc64aeb1b6387039d09019c214352 Mon Sep 17 00:00:00 2001
From: Mark Fasheh <mark.fasheh@oracle.com>
Date: Tue, 12 Sep 2006 21:24:53 -0700
Subject: ocfs2: Clean up lock resource refresh flags

Use of the refresh mechanism is lock-type wide, so move knowledge of that to
the ocfs2_lock_res_ops structure.

Subject: ocfs2: combine inode and generic AST functions

There is extremely little difference between the two now. We can remove the
callback from ocfs2_lock_res_ops as well.

Subject: ocfs2: remove ->unlock_ast() callback from ocfs2_lock_res_ops

This was always defined to the same function in all locks, so clean things
up by removing and passing ocfs2_unlock_ast() directly to the DLM.

Subject: ocfs2: combine inode and generic blocking AST functions

There is extremely little difference between the two now. We can remove the
callback from ocfs2_lock_res_ops as well.

Subject: ocfs2: don't unconditionally pass LVB flags

Allow a lock type to specifiy whether it makes use of the LVB. The only type
which does this right now is the meta data lock. This should save us some
space on network messages since they won't have to needlessly transmit value
blocks.

Subject: ocfs2: Remove ->unblock lockres operation

Have ocfs2_process_blocked_lock() call ocfs2_generic_unblock_lock(), which
gets to be ocfs2_unblock_lock() now that it's the only possible unblock
function.

Remove the ->unblock() callback from the structure, and all lock type
specific unblock functions.

Subject: ocfs2: Teach ocfs2_drop_lock() to use ->set_lvb() callback

With this, we don't need to pass an additional struct with function pointer.

Now that the callbacks are fully used, comment the remaining API.

Subject: kconfig: support DOS line endings

Kconfig doesn't currently handle config files with DOS line endings.
While these are, of course, an abomination, etc, etc, it can be handy
to not have to convert them first.  It's also a tiny patch and even adds
support for lines ending in just \r or even \n\r.

Subject: kbuild: consistently decide when to rebuild a target

Consistently decide when to rebuild a target across all of
if_changed, if_changed_dep, if_changed_rule.
PHONY targets are now treated alike (ignored) for all targets

While add it make Kbuild.include almost readable by factoring out a few
bits to some common variables and reuse this in Makefile.build.

Subject: kbuild: add unifdef

This patch contains a raw copy of unifdef.c
Next patch will modify it and add infrastructure to use it
Adding unifdef to the kernel is acked by the author.

The reason to add unifdef as part of the kernel source is that it is not
yet a common utility on most distributions.

+ * alter the preprocessor directive, as follows.
+ *
+ * When we have processed a group that starts off with a known-false

+ * always be kept and the rest of the sequence after the next #elif or
+ * #else will be discarded. We edit the #elif into a #else and the
+ * following directive to #endif since this has the desired behaviour.
+ *
+ * "Dodgy" directives are split across multiple lines, the most common
+ * example being a multi-line comment hanging off the right of the
+ * directive. We can handle them correctly only if there is no change
+ * from printing to dropping (or vice versa) caused by that directive.

Subject: remove RPM_BUILD_ROOT from asm-offsets.h

No file in rpm binary package should have the RPM_BUILD_ROOT string in it.
To simplify building of external modules, our kernel-source package
contains some temp files from the Kbuild system.  asm/asm-offsets.h is one
of the files that contains the absolute path if make O=$O is used.

  * This file was generated by /var/tmp/kernel-source-2.6.14_rc4-build/usr/src/linux-2.6.14-rc4-2/Kbuild

Remove the $RPM_BUILD_ROOT string in the shipped tempfile.

Subject: kbuild: modpost on vmlinux regardless of CONFIG_MODULES

Based on patch from: Magnus Damm <magnus@valinux.co.jp>
This has the advantage that all section mismatch checks are run regardless
of modules being enabled or not.

When running modpost on vmlinux output:
MODPOST vmlinux

When running modpost on modules output count of modules like this:
MODPOST 5 modules

Subject: kbuild: make V=2 tell why a target is rebuild

tell why a a target got build
   enabled by make V=2
      Output (listed in the order they are checked):
         (1) - due to target is PHONY
         (2) - due to target missing
         (3) - due to: file1.h file2.h
         (4) - due to command line change
         (5) - due to missing .cmd file
         (6) - due to target not in $(targets)
(1) We always build PHONY targets
(2) No target, so we better build it
(3) Prerequisite is newer than target
(4) The command line stored in the file named dir/.target.cmd
    differed from actual command line. This happens when compiler
    options changes
(5) No dir/.target.cmd file (used to store command line)
(6) No dir/.target.cmd file and target not listed in $(targets)
    This is a good hint that there is a bug in the kbuild file

Subject: kbuild: fail kernel compilation in case of unresolved module symbols

At stage 2 modpost utility is used to check modules.  In case of unresolved
symbols modpost only prints warning.

IMHO it is a good idea to fail compilation process in case of unresolved
symbols (at least in modules coming with kernel), since usually such errors
are left unnoticed, but kernel modules are broken.

- new option '-w' is added to modpost:
  if option is specified, modpost only warns about unresolved symbols

- modpost is called with '-w' for external modules in Makefile.modpost

From: Aron Griffis <aron@hp.com>
Date: Thu, 21 Sep 2006 00:27:02 -0400
Subject: kbuild: Extend kbuild/defconfig tags support to exuberant ctags

The following patch extends kbuild/defconfig tags support to exuberant
ctags.  The previous support is only for emacs ctags/etags programs.

This patch also corrects the kconfig regex for the emacs invocation.
Previously it would miss some instances because it assumed /^config
instead of /^[ \t]*config

Subject: kbuild: fix "mkdir -p" usage in scripts/package/mkspec

"mkdir -p" does not only mean not to complain if the directory already
exists, but also to create the parent directories if needed. This patch
removes "lib" from the list of directories to create as we will also create
"lib/modules".

Some user tools parse /proc/scsi/scsi, so we can't yet change the names.
Change the existing ones back to their old names, and add an admonition
to not make the same mistake that I did.

Andrew Morton reports that this was breaking YDL 4.1 userspace.

Subject: [PATCH] wrong thing iounmapped (qla3xxx)

ql3xxx_probe() does ioremap and stores result in ->mem_map_registers.
On failure exit it does iounmap() of the same thing.

OTOH, ql3xxx_remove() does iounmap() of ->mmap_virt_base which is
 (a) never assigned and
 (b) never used other than in that iounmap() call.
