From 45b3947c2de5841d691f1d27d30419b9fae2d86c Mon Sep 17 00:00:00 2001 From: Al Viro Date: Mon, 12 May 2008 11:55:10 +0800 Subject: [Blackfin] arch: Blackfin checksum annotations FSVOtest in this case, since I don't have the hardware... However, all changes seen by gcc are actually - explicit cast to unsigned short in return expression of functions returning unsigned short - csum_fold() return type changed from unsigned int to __sum16 (unsigned short), same as for all other architecture and as net/* expects; expression actually returned is ((~(sum << 16)) >> 16) with sum being unsigned 32bit, so it's (a) going to fit into the range of unsigned short and (b) had been unsigned all along, so no sign expansion mess happened.

It should also use the standard __u## types from linux/types.h rather than the uint##_t types since the former can be found with the kernel already. Same goes for linux/atm.h.

This patch restores ieee80211_iterate_active_interfaces() to use RTNL lock, and provides the non-RTNL version under a new name: ieee80211_iterate_active_interfaces_atomic() So far only rt2x00 uses ieee80211_iterate_active_interfaces(), and those drivers require the RTNL version of ieee80211_iterate_active_interfaces().

There are two principal pieces of data that need to be tracked: the list of pages that comprise the completed RPC and the SGE of dma mapped pages to refer to this list of pages. Previously this whole bit was managed as a linked list of contexts with the context containing the page list buried in this list. This patch simplifies this processing by not keeping a linked list, but rather only a pionter from the last submitted RDMA_READ's context to the context that maps the set of pages that describe the RPC. This significantly simplifies this code path. SGE contexts are cleaned up inline in the DTO path instead of at read completion time.

Miller" Date: Mon, 19 May 2008 23:46:00 -0700 Subject: sparc64: Add global register dumping facility. When a cpu really is stuck in the kernel, it can be often impossible to figure out which cpu is stuck where. The worst case is when the stuck cpu has interrupts disabled. Therefore, implement a global cpu state capture that uses SMP message interrupts which are not disabled by the normal IRQ enable/disable APIs of the kernel. As long as we can get a sysrq 'y' to the kernel, we can get a dump. Even if the console interrupt cpu is wedged, we can trigger it from userspace using /proc/sysrq-trigger The output is made compact so that this facility is more useful on high cpu count systems, which is where this facility will likely find itself the most useful :) Signed-off-by: David S.

Since 2.6.25 the HID_QUIRK_APPLE_HAS_FN quirk is enabled even for non-laptop Apple keyboards of the Aluminium series. The USB version of these don't need Numlock emulation, like the laptop (and Aluminium Wireless) do, as they have a proper keypad. This patch splits the Numlock emulation for Apple keyboards in a different quirk flag, so that it can be enabled for all the keyboards but the Aluminium USB ones. If the Numlock emulation is enabled for Aluminium USB keyboards, the JKL and UIO keys become the numeric pad, and the rest of the keyboard is disabled, included the key used to disable Numlock. Additionally, these keyboard should not have a Numlock at all, as the Numlock key is instead replaced by the 'Clear' key as usual for Apple USB keyboards.

It is now defined as a pteval_t, which is an integer type long enough to contain a full pte (or pmd, pud, pgd). This fixes an Xorg crash on 32-bit x86 with PAE due to corruption of the NX bit in mprotect due to the incorrect type/value of PTE_MASK reported by Hugh Dickins: "Yes, thanks Jeremy: I've checked that each stage builds and runs X on my boxes here, x86_32 and x86_32+PAE and x86_64.

So far, it called nla_parse_nested() to parse the stream of nested attributes which was wrong, as nla_parse_nested() expects a container attribute as data which holds the attribute stream. It needs to call nla_parse() directly while pointing at the next possible alignment point after the struct in the beginning of the attribute.

In some configurations, a raid6 resync can be limited by CPU speed (Calculating P and Q and moving data) rather than by device speed. In these cases there is nothing to be gained byt serialising resync of arrays that share a device, and doing the resync in parallel can provide benefit. So add a sysfs tunable to flag an array as being allowed to resync in parallel with other arrays that use (a different part of) the same device.

When we get any IO error during a recovery (rebuilding a spare), we abort the recovery and restart it. For RAID6 (and multi-drive RAID1) it may not be best to restart at the beginning: when multiple failures can be tolerated, the recovery may be able to continue and re-doing all that has already been done doesn't make sense. We already have the infrastructure to record where a recovery is up to and restart from there, but it is not being used properly. This is because: - We sometimes abort with MD_RECOVERY_ERR rather than just MD_RECOVERY_INTR, which causes the recovery not be be checkpointed. - We remove spares and then re-added them which loses important state information. The distinction between MD_RECOVERY_ERR and MD_RECOVERY_INTR really isn't needed. If there is an error, the relevant drive will be marked as Faulty, and that is enough to ensure correct handling of the error. So we first remove MD_RECOVERY_ERR, changing some of the uses of it to MD_RECOVERY_INTR. Then we cause the attempt to remove a non-faulty device from an array to fail (unless recovery is impossible as the array is too degraded). Then when remove_and_add_spares attempts to remove the devices on which recovery can continue, it will fail, they will remain in place, and recovery will continue on them as desired. Issue: If we are halfway through rebuilding a spare and another drive fails, and a new spare is immediately available, do we want to: 1/ complete the current rebuild, then go back and rebuild the new spare or 2/ restart the rebuild from the start and rebuild both devices in parallel. Both options can be argued for. The code currently takes option 2 as a/ this requires least code change b/ this results in a minimally-degraded array in minimal time.

Perhaps not a bug, but people find this surprising.

Such faults may initiate a cascade of repeated illegal operation faults within OS interruption handlers. The specific behavior is OS dependent. Implication: An application causing an illegal operation fault with specific RSE state may result in a series of illegal operation faults and an eventual OS stack overflow condition. Workaround: OS interruption handlers that switch to kernel backing store implement a check for invalid RSE state to avoid the series of illegal operation faults. The core of the workaround is the RSE_WORKAROUND code sequence inserted into each invocation of the SAVE_MIN_WITH_COVER and SAVE_MIN_WITH_COVER_R19 macros. This sequence includes hard-coded constants that depend on the number of stacked physical registers being 96. The rest of this patch consists of code to disable this workaround should this not be the case (with the presumption that if a future Itanium processor increases the number of registers, it would also remove the need for this patch). Move the start of the RBS up to a mod32 boundary to avoid some corner cases. The dispatch_illegal_op_fault code outgrew the spot it was squatting in when built with this patch and CONFIG_VIRT_CPU_ACCOUNTING=y Move it out to the end of the ivt.

There's a similar mechanism for the host to suppress notifications coming from the guest: in that case, we ignore the suppression if the ring is completely full. It turns out that life is simpler if the host similarly ignores callback suppression when the ring is completely empty: the network driver wants to free up old packets in a timely manner, and otherwise has to use a timer to poll. We have to remove the code which ignores interrupts when the driver has disabled them (again, it had no locking and hence was unreliable anyway).

Morgan" Date: Tue, 27 May 2008 22:05:17 -0700 Subject: capabilities: remain source compatible with 32-bit raw legacy capability support. Source code out there hard-codes a notion of what the _LINUX_CAPABILITY_VERSION #define means in terms of the semantics of the raw capability system calls capget() and capset(). Its unfortunate, but true. Since the confusing header file has been in a released kernel, there is software that is erroneously using 64-bit capabilities with the semantics of 32-bit compatibilities. These recently compiled programs may suffer corruption of their memory when sys_getcap() overwrites more memory than they are coded to expect, and the raising of added capabilities when using sys_capset(). As such, this patch does a number of things to clean up the situation for all. It 1. forces the _LINUX_CAPABILITY_VERSION define to always retain its legacy value. 2. adopts a new #define strategy for the kernel's internal implementation of the preferred magic. 3. deprecates v2 capability magic in favor of a new (v3) magic number. The functionality of v3 is entirely equivalent to v2, the only difference being that the v2 magic causes the kernel to log a "deprecated" warning so the admin can find applications that may be using v2 inappropriately. [User space code continues to be encouraged to use the libcap API which protects the application from details like this. libcap-2.10 is the first to support v3 capabilities.] Fixes issue reported in https://bugzilla.redhat.com/show_bug.cgi?id=447518. Thanks to Bojan Smojver for the report.

The FRV, SH and Xtensa ports are also missing a memory clobber, so I thought it would be polite to let you know. The bug manifests as dropped network packets (obviously they have the wrong checksum). It started appearing for parisc with GCC 4.3. The GCC manual says: If your assembler instructions access memory in an unpredictable fashion, add `memory' to the list of clobbered registers. This will cause GCC to not keep memory values cached in registers across the assembler instruction and not optimize stores or loads to that memory. I see that FRV has a 400 byte memory output which may prevent this problem from appearing, but SH and Xtensa have nothing to prevent this bug. Hope this saves you a few days of debugging.

Some hardware uses this to configure hardware specific features such as IrDA mode on serial ports. Unfortunately the serial layer does not provide this feature or pass it down to drivers. Blackfin used to hack around this by rewriting the tty ops, but those are now properly shared and const so the hack fails. Instead provide the proper operations. This change plus a follow up from the Blackfin guys is needed to avoid blackfin losing features in this release.

However, the support was incomplete: the completion structure was not extended with a field for the key contained in incoming send with invalidate requests. Full support for memory management extensions (send with invalidate, local invalidate, fast register through a send queue, etc) is planned for 2.6.27. Since send with invalidate is not very useful by itself, just remove the IB_DEVICE_SEND_W_INV bit before the 2.6.26 final release; we will add an IB_DEVICE_MEM_MGT_EXTENSIONS bit in 2.6.27, which makes things simpler for applications, since they will not have quite as confusing an array of fine-grained bits to check.

However, the code like current->state = TASK_KILLABLE; schedule(); is not right, schedule() doesn't take TASK_WAKEKILL into account. This means that mutex_lock_killable(), wait_for_completion_killable(), down_killable(), schedule_timeout_killable() can miss SIGKILL (and btw the second SIGKILL has no effect). Introduce the new helper, signal_pending_state(), and change schedule() to use it. Hopefully it will have more users, that is why the task's state is passed separately. Note this "__TASK_STOPPED | __TASK_TRACED" check in signal_pending_state(). This is needed to preserve the current behaviour (ptrace_notify). I hope this check will be removed soon, but this (afaics good) change needs the separate discussion. The fast path is "(state & (INTERRUPTIBLE | WAKEKILL)) + signal_pending(p)", basically the same that schedule() does now. However, this patch of course bloats schedule().

Due to this bug, there will be oops on AC<->DC on some systems, where they support C-states in one DC and not in AC. The current code does ON BOOT: Look at CST and other C-state info to see whether more than C1 is supported. If it is, then acpi processor_idle does a cpuidle_register_driver() call, which internally enables the device. ON CST change notification (AC<->DC) and on suspend-resume: acpi driver temporarily disables device, updates the device with any new C-states, and reenables the device. The problem is is on boot, there are no C2, C3 states supported and we skip the register. Later on AC<->DC, we may get a CST notification and we try to reevaluate CST and enabled the device, without actually registering it. This causes breakage as we try to create /sys fs sub directory, without the parent directory which is created at register time.

Unfortunately modern gcc's have the tendency to strength "reduce" this into a full mod operation, which isn't necessarily any faster, and even if it were, doesn't exist if gcc implements it in libgcc. The workaround is to put a dummy asm statement in the loop to prevent gcc from performing the transformation. This patch creates a single implementation of this loop, and uses it to replace the open-coded versions I know about.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This reverts two changesets, ec3c0982a2dd1e671bad8e9d26c28dcba0039d87 ("[TCP]: TCP_DEFER_ACCEPT updates - process as established") and the follow-on bug fix 9ae27e0adbf471c7a6b80102e38e1d5a346b3b38 ("tcp: Fix slab corruption with ipv6 and tcp6fuzz"). This change causes several problems, first reported by Ingo Molnar as a distcc-over-loopback regression where connections were getting stuck. Ilpo Järvinen first spotted the locking problems. The new function added by this code, tcp_defer_accept_check(), only has the child socket locked, yet it is modifying state of the parent listening socket. Fixing that is non-trivial at best, because we can't simply just grab the parent listening socket lock at this point, because it would create an ABBA deadlock. The normal ordering is parent listening socket --> child socket, but this code path would require the reverse lock ordering. Next is a problem noticed by Vitaliy Gusev, he noted: ---------------------------------------- >--- a/net/ipv4/tcp_timer.c >+++ b/net/ipv4/tcp_timer.c >@@ -481,6 +481,11 @@ static void tcp_keepalive_timer (unsigned long data) > goto death; > } > >+ if (tp->defer_tcp_accept.request && sk->sk_state == TCP_ESTABLISHED) { >+ tcp_send_active_reset(sk, GFP_ATOMIC); >+ goto death; Here socket sk is not attached to listening socket's request queue. tcp_done() will not call inet_csk_destroy_sock() (and tcp_v4_destroy_sock() which should release this sk) as socket is not DEAD. Therefore socket sk will be lost for freeing. ---------------------------------------- Finally, Alexey Kuznetsov argues that there might not even be any real value or advantage to these new semantics even if we fix all of the bugs: ---------------------------------------- Hiding from accept() sockets with only out-of-order data only is the only thing which is impossible with old approach. Is this really so valuable? My opinion: no, this is nothing but a new loophole to consume memory without control. ---------------------------------------- So revert this thing for now.

When a 64-bit x86 processor runs in 32-bit PAE mode, a pte can potentially have the same number of physical address bits as the 64-bit host ("Enhanced Legacy PAE Paging"). This means, in theory, we could have up to 52 bits of physical address in a pte. The 32-bit kernel uses a 32-bit unsigned long to represent a pfn. This means that it can only represent physical addresses up to 32+12=44 bits wide. Rather than widening pfns everywhere, just set 2^44 as the Linux x86_32-PAE architectural limit for physical address size. This is a bugfix for two cases: 1. running a 32-bit PAE kernel on a machine with more than 64GB RAM. 2. running a 32-bit PAE Xen guest on a host machine with more than 64GB RAM In both cases, a pte could need to have more than 36 bits of physical, and masking it to 36-bits will cause fairly severe havoc.

Which doesn't work for per cpu variables in modules, as an offset to the kernel per cpu area is way above 4G. The workaround is to force allocation of a GOT entry for per cpu variable using ldq instruction with a 'literal' relocation.

We cannot just convert "extern inline" to "static inline", as people keep suggesting all the time, because "extern inline" logic is crucial for generic kernel build. So - just make sure that all callees of critical "extern inline" functions are also "extern inline"; - use "static inline", wherever it's possible. traps.c: work around gcc-4.3 being too smart about array bounds-checking. TODO: add "gnu_inline" attribute to all our "extern inline" functions to ensure desired behaviour with future compilers.

Receiving packets while we are cleaning up a network namespace is a racy proposition. It is possible when the packet arrives that we have removed some but not all of the state we need to fully process it. We have the choice of either playing wack-a-mole with the cleanup routines or simply dropping packets when we don't have a network namespace to handle them.
