8e9d78e Linus Torvalds 22 August 2009, 00:40:08 UTC Re-introduce page mapping check in mark_buffer_dirty() In commit a8e7d49aa7be728c4ae241a75a2a124cdcabc0c5 ("Fix race in create_empty_buffers() vs __set_page_dirty_buffers()"), I removed a test for a NULL page mapping unintentionally when some of the code inside __set_page_dirty() was moved to the callers. That removal generally didn't matter, since a filesystem would serialize truncation (which clears the page mapping) against writing (which marks the buffer dirty), so locking at a higher level (either per-page or an inode at a time) should mean that the buffer page would be stable. And indeed, nothing bad seemed to happen. Except it turns out that apparently reiserfs does something odd when under load and writing out the journal, and we have a number of bugzilla entries that look similar: http://bugzilla.kernel.org/show_bug.cgi?id=13556 http://bugzilla.kernel.org/show_bug.cgi?id=13756 http://bugzilla.kernel.org/show_bug.cgi?id=13876 and it looks like reiserfs depended on that check (the common theme seems to be "data=journal", and a journal writeback during a truncate). I suspect reiserfs should have some additional locking, but in the meantime this should get us back to the pre-2.6.29 behavior.

b04e637 Linus Torvalds 21 August 2009, 16:48:10 UTC x86: don't call '->send_IPI_mask()' with an empty mask As noted in 83d349f35e1ae72268c5104dbf9ab2ae635425d4 ("x86: don't send an IPI to the empty set of CPU's"), some APIC's will be very unhappy with an empty destination mask. That commit added a WARN_ON() for that case, and avoided the resulting problem, but didn't fix the underlying reason for why those empty mask cases happened. This fixes that, by checking the result of 'cpumask_andnot()' of the current CPU actually has any other CPU's left in the set of CPU's to be sent a TLB flush, and not calling down to the IPI code if the mask is empty. The reason this started happening at all is that we started passing just the CPU mask pointers around in commit 4595f9620 ("x86: change flush_tlb_others to take a const struct cpumask"), and when we did that, the cpumask was no longer thread-local. Before that commit, flush_tlb_mm() used to create it's own copy of 'mm->cpu_vm_mask' and pass that copy down to the low-level flush routines after having tested that it was not empty. But after changing it to just pass down the CPU mask pointer, the lower level TLB flush routines would now get a pointer to that 'mm->cpu_vm_mask', and that could still change - and become empty - after the test due to other CPU's having flushed their own TLB's. See http://bugzilla.kernel.org/show_bug.cgi?id=13933 for details.

f4b0373 Linus Torvalds 21 August 2009, 16:26:15 UTC Make bitmask 'and' operators return a result code When 'and'ing two bitmasks (where 'andnot' is a variation on it), some cases want to know whether the result is the empty set or not. In particular, the TLB IPI sending code wants to do cpumask operations and determine if there are any CPU's left in the final set. So this just makes the bitmask (and cpumask) functions return a boolean for whether the result has any bits set.

83d349f Linus Torvalds 21 August 2009, 16:23:57 UTC x86: don't send an IPI to the empty set of CPU's The default_send_IPI_mask_logical() function uses the "flat" APIC mode to send an IPI to a set of CPU's at once, but if that set happens to be empty, some older local APIC's will apparently be rather unhappy. So just warn if a caller gives us an empty mask, and ignore it. This fixes a regression in 2.6.30.x, due to commit 4595f9620 ("x86: change flush_tlb_others to take a const struct cpumask"), documented here: http://bugzilla.kernel.org/show_bug.cgi?id=13933 which causes a silent lock-up. It only seems to happen on PPro, P2, P3 and Athlon XP cores. Most developers sadly (or not so sadly, if you're a developer..) have more modern CPU's. Also, on x86-64 we don't use the flat APIC mode, so it would never trigger there even if the APIC didn't like sending an empty IPI mask.

This causes inode tree corruption and I was seeing crashes in inode_tree_del which I can not reproduce after this patch. The other way to fix this would be to tie inode lifetime in the rbtree with inode while not in freeing state. I had a look at this but it is not so trivial at this point. At least this patch gets things working again.

This is a regression due to the previous clean-up work to merge all Toshiba quirk entries into a single check. This patch adds the identification of such laptops to apply the standard BIOS-probing method. Unfortunately, Toshiba laptops have all the same PCI SSID, so we need to check the codec SSID to identify each device.

0753ba0 KOSAKI Motohiro 18 August 2009, 21:11:10 UTC mm: revert "oom: move oom_adj value" The commit 2ff05b2b (oom: move oom_adj value) moveed the oom_adj value to the mm_struct. It was a very good first step for sanitize OOM. However Paul Menage reported the commit makes regression to his job scheduler. Current OOM logic can kill OOM_DISABLED process. Why? His program has the code of similar to the following. ... set_oom_adj(OOM_DISABLE); /* The job scheduler never killed by oom */ ... if (vfork() == 0) { set_oom_adj(0); /* Invoked child can be killed */ execve("foo-bar-cmd"); } .... vfork() parent and child are shared the same mm_struct. then above set_oom_adj(0) doesn't only change oom_adj for vfork() child, it's also change oom_adj for vfork() parent. Then, vfork() parent (job scheduler) lost OOM immune and it was killed. Actually, fork-setting-exec idiom is very frequently used in userland program. We must not break this assumption. Then, this patch revert commit 2ff05b2b and related commit.

This turns out to be a bug brought by an -rc1 patch ("nilfs2: simplify remaining sget() use"). In the patch, a new "put resource" function, nilfs_put_sbinfo() was introduced to delay freeing nilfs_sb_info struct. But the nilfs_put_sbinfo() mistakenly used atomic_dec_and_test() function to check the reference count, and it caused the nilfs_sb_info was freed when user mounted a snapshot twice. This bug also suggests there was unseen memory leak in usual mount /umount operations for nilfs. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp> 18 August 2009, 17:10:13 UTC

Restoring old behavior is not welcome, for performance reason.

In 7e790dd5 we changed from starting at 1 to starting at 0. This patch starts at 1, just like in previous kernels, but also just like in previous kernels it's possible for it to wrap back to 0.

e412cd2 Ingo Molnar 17 August 2009, 08:19:00 UTC x86, mce: Don't initialize MCEs on unknown CPUs An older test-box started hanging at the following point during bootup: [ 0.022996] Mount-cache hash table entries: 512 [ 0.024996] Initializing cgroup subsys debug [ 0.025996] Initializing cgroup subsys cpuacct [ 0.026995] Initializing cgroup subsys devices [ 0.027995] Initializing cgroup subsys freezer [ 0.028995] mce: CPU supports 5 MCE banks I've bisected it down to commit 4efc0670 ("x86, mce: use 64bit machine check code on 32bit"), which utilizes the MCE code on 32-bit systems too. The problem is caused by this detail in my config: # CONFIG_CPU_SUP_INTEL is not set This disables the quirks in mce_cpu_quirks() but still enables MCE support - which then hangs due to the missing quirk workaround needed on this CPU: if (c->x86 == 6 && c->x86_model < 0x1A && banks > 0) mce_banks[0].init = 0; The safe solution is to not initialize MCEs if we dont know on what CPU we are running (or if that CPU's support code got disabled in the config). Also be a bit more defensive on 32-bit systems: dont do a boot-time dump of pending MCEs not just on the specific system that we found a problem with (Pentium-M), but earlier ones as well. Now this problem is probably not common and disabling CPU support is rare - but still being more defensive in something we turned on for a wide range of CPUs is prudent.

e1ac361 Paul Mackerras 14 August 2009, 05:39:10 UTC perf_counter: Check task on counter read IPI In general, code in perf_counter.c that is called through an IPI checks, for per-task counters, that the counter's task is still the current task. This is to handle the race condition where the cpu switches from the task we want to another task in the interval between sending the IPI and the IPI arriving and being handled on the target CPU. For some reason, __perf_counter_read is missing this check, yet there is no reason why the race condition can't occur. This adds a check that the current task is the one we want. If it isn't, we just return. In that case the counter->count value should be up to date, since it will have been updated when the counter was scheduled out, which must have happened since the IPI was sent. I don't have an example of an actual failure due to this race, but it seems obvious that it could occur and we need to guard against it.

bc990f5 Christoph Hellwig 17 August 2009, 00:36:34 UTC xfs: fix locking in xfs_iget_cache_hit The locking in xfs_iget_cache_hit currently has numerous problems: - we clear the reclaim tag without i_flags_lock which protects modifications to it - we call inode_init_always which can sleep with pag_ici_lock held (this is oss.sgi.com BZ #819) - we acquire and drop i_flags_lock a lot and thus provide no consistency between the various flags we set/clear under it This patch fixes all that with a major revamp of the locking in the function. The new version acquires i_flags_lock early and only drops it once we need to call into inode_init_always or before calling xfs_ilock.

This patch causes SELinux to ignore the tunable and instead use a seperate Kconfig option specific to how much space the LSM should protect. The tunable will now only control the need for CAP_SYS_RAWIO and SELinux permissions will always protect the amount of low memory designated by CONFIG_LSM_MMAP_MIN_ADDR. This allows users who need to disable the mmap_min_addr controls (usual reason being they run WINE as a non-root user) to do so and still have SELinux controls preventing confined domains (like a web server) from being able to map some area of low memory.

It was first set to 1 in pollwake() (now __pollwake() ), tested and later set to 0 in poll_schedule_timeout(), but not initialized before. As a result when the process needs to sleep, triggered was likely to be non-zero even if pollwake() is not called before the first poll_schedule_timeout(), meaning schedule_hrtimeout_range() would not be called and an extra loop calling all ->poll() would be done.

dde5828 Russell King 15 August 2009, 11:36:00 UTC ARM: Fix broken highmem support Currently, highmem is selectable, and you can request an increased vmalloc area. However, none of this has any effect on the memory layout since a patch in the highmem series was accidentally dropped. Moreover, even if you did want highmem, all memory would still be registered as lowmem, possibly resulting in overflow of the available virtual mapping space. The highmem boundary is determined by the highest allowed beginning of the vmalloc area, which depends on its configurable minimum size (see commit 60296c71f6c5063e3c1f1d2619ca0b60940162e7 for details on this). We should create mappings and initialize bootmem only for low memory, while the zone allocator must still be told about highmem. Currently, memory nodes which are completely located in high memory are not supported. This is not a huge limitation since systems relying on highmem support are unlikely to have discontiguous memory with large holes. [ A similar patch was meant to be merged before commit 5f0fbf9ecaf3 and be available in Linux v2.6.30, however some git rebase screw-up of mine dropped the first commit of the series, and that goofage escaped testing somehow as well. -- Nico ] Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Reviewed-by: Nicolas Pitre <nico@marvell.com> 15 August 2009, 11:36:00 UTC
