Lennert Buytenhek noticed that delBA handling in mac80211
was broken and has remotely triggerable problems, some of
which are due to some code shuffling I did that ended up
changing the order in which things were done -- this was
commit d75636ef9c1af224f1097941879d5a8db7cd04e5
Author: Johannes Berg <johannes@sipsolutions.net>
Date: Tue Feb 10 21:25:53 2009 +0100
mac80211: RX aggregation: clean up stop session
and other parts were already present in the original
commit d92684e66091c0f0101819619b315b4bb8b5bcc5
Author: Ron Rindjunsky <ron.rindjunsky@intel.com>
Date: Mon Jan 28 14:07:22 2008 +0200
mac80211: A-MPDU Tx add delBA from recipient support
The first problem is that I moved a BUG_ON before various
checks -- thereby making it possible to hit. As the comment
indicates, the BUG_ON can be removed since the ampdu_action
callback must already exist when the state is != IDLE.
The second problem isn't easily exploitable but there's a
race condition due to unconditionally setting the state to
OPERATIONAL when a delBA frame is received, even when no
aggregation session was ever initiated. All the drivers
accept stopping the session even then, but that opens a
race window where crashes could happen before the driver
accepts it. Right now, a WARN_ON may happen with non-HT
drivers, while the race opens only for HT drivers.
For this case, there are two things necessary to fix it:
1) don't process spurious delBA frames, and be more careful
about the session state; don't drop the lock
2) HT drivers need to be prepared to handle a session stop
even before the session was really started -- this is
true for all drivers (that support aggregation) but
iwlwifi which can be fixed easily. The other HT drivers
(ath9k and ar9170) are behaving properly already.

Fixes kernel bugzilla #14691
Due to the way netpoll works, it is perfectly legal to see
NAPI already scheduled when new device events are pending
in b44_interrupt().
So logging a message about it is wrong and in fact harmful.

If we happen to have registered the driver without passing
a MAC address, we will print a zero MAC address and register
the interface with this invalid address, this is confusin. This

smc91x.h defines SMC_IRQ_FLAGS to be -1 when it wants the interrupt
flags to be taken from the resource structure. However, d280ead
changed this to checking for non-zero resource flags.
Unfortunately, this means that on some platforms, we end up passing
'-1' to request_irq rather than the desired result. Combine the two
conditions into one so that the IRQ flags are taken from the resource
if either SMC_IRQ_FLAGS is -1 or the resource flags specify an
interrupt trigger.
This restores network on at least the Versatile platform.

The newer chipsets (all PCI-E) are known that they need full power cycle
(AC or battery removal) to reset MAC address to a hardwired one. Previous
patch to address this problem loads the original MAC address from EEPROM.
But it brought other problem for which it is necessary to introduce a new
module parameter.
However, it might suffice to restore the initial MAC address before
shutdown/reboot/kexec and when removing the module.

This patch (as1305) fixes a bug in the irq-enable settings and removes
some related overhead in the runtime PM code.
In __pm_runtime_resume(), within the scope of the original
spin_lock_irq(), we know that irqs are disabled. There's no
reason to go through a pair of enable/disable cycles when
acquiring and releasing the parent's lock.
In __pm_runtime_set_status(), irqs are already disabled when
the parent's lock is acquired, and they must remain disabled
when it is released.

__scsi_remove_device() in scsi_forget_host() is executed out of scan_mutex
and races with scsi_destroy_sdev() <- scsi_sysfs_add_devices() <-
scsi_finish_async_scan(). The result is use after free and/or double
free, oops.
The fix is simple, move scsi_forget_host() under scan_mutex.
scsi_forget_host() is just sequence of __scsi_remove_device(). All
another calls of __scsi_remove_device() are made under scan_mutex. So
that it is safe.

Async scanning introduced a very wide window where the SCSI device is
up and running but has not yet been added to sysfs. We delay the
adding until all scans have completed to retain the same ordering as
sync scanning.
This delay in visibility causes an oops if a device is removed before
we make it visible because the SCSI removal routines have an inbuilt
assumption that if a device is in SDEV_RUNNING state, it must be
visible (which is not necessarily true in the async scanning case).
Fix this by introducing an additional is_visible flag which we can use
to condition the tear down so we do the right thing for running but
not yet made visible.

# echo 24c08 0x50 > /sys/bus/i2c/devices/i2c-3/new_device
# rmmod i2c-stub

of UDMA6
Currently, ide_cmd_ioctl when invoked for setting DMA transfer mode calls
ide_find_dma_mode with requested mode as XFER_UDMA_6. This prevents setting DMA
mode to any other value than the default (maximum) supported by the device (or
UDMA6, if supported) irrespective of the actual requested transfer mode and
returns error.
For example, setting mode to UDMA2 using hdparm, where UDMA4 is the default
transfer mode gives following error:
# ./hdparm -d1 -Xudma2 /dev/hda
/dev/hda:hda: UDMA/66 mode selected
setting using_dma to 1 (on)
hda: UDMA/66 mode selected
setting xfermode to 66 (UltraDMA mode2)

There is a problem in the quirk tables used by tpacpi_is_fw_known() and
tpacpi_check_outdated_fw(), which causes outdated BIOSes that are lacking
the EC firmware ID DMI field to never match.
This breaks module loading on, e.g. a T23 with outdated BIOS, and the
module will refuse to load unless the "force_load=1" parameter is given.
Fix the quirk tables so that they can also match the outdated BIOSes,
which in turn will both fix the module loading, and also warn the user
that he is using outdated firmware and should upgrade.
This fixes a serious regression, introduced by commit
e675abafcc0df38125e6e94a9ba91c92fe774f52, "thinkpad-acpi: be more strict
when detecting a ThinkPad".
