The current offset was not being set for the first dirent in the temporary buffer, which coul dresult in bad offsets being set in the f_pos field result in looping and duplicate entries being returned from readdir.

bad60fd Christoph Hellwig 20 December 2007, 23:58:56 UTC [XFS] Fix mknod regression This was broken by my '[XFS] simplify xfs_create/mknod/symlink prototype', which assigned the re-shuffled ondisk dev_t back to the rdev variable in xfs_vn_mknod. Because of that i_rdev is set to the ondisk dev_t instead of the linux dev_t later down the function. Fortunately the fix for it is trivial: we can just remove the assignment because xfs_revalidate_inode has done the proper job before unlocking the inode.

c0a698b Ingo Molnar 21 December 2007, 00:27:19 UTC x86: fix die() to not be preemptible Andrew "Eagle Eye" Morton noticed that we use raw_local_save_flags() instead of raw_local_irq_save(flags) in die(). This allows the preemption of oopsing contexts - which is highly undesirable. It also causes CONFIG_DEBUG_PREEMPT to complain, as reported by Miles Lane. this bug was introduced via: commit 39743c9ef717fd4f2b5583f010115c5f2482b8ae Author: Andi Kleen <ak@suse.de> Date: Fri Oct 19 20:35:03 2007 +0200 x86: use raw locks during oopses - spin_lock_irqsave(&die.lock, flags); + __raw_spin_lock(&die.lock); + raw_local_save_flags(flags); that is not a correct open-coding of spin_lock_irqsave(): both the ordering is wrong (irqs should be disabled _first_), and the wrong flags-saving API was used.

91e1062 Milan Broz 13 December 2007, 14:16:10 UTC dm crypt: use bio_add_page Fix possible max_phys_segments violation in cloned dm-crypt bio. In write operation dm-crypt needs to allocate new bio request and run crypto operation on this clone. Cloned request has always the same size, but number of physical segments can be increased and violate max_phys_segments restriction. This can lead to data corruption and serious hardware malfunction. This was observed when using XFS over dm-crypt and at least two HBA controller drivers (arcmsr, cciss) recently. Fix it by using bio_add_page() call (which tests for other restrictions too) instead of constructing own biovec. All versions of dm-crypt are affected by this bug.

512875b Jun'ichi Nomura 13 December 2007, 14:15:25 UTC dm: table detect io beyond device This patch fixes a panic on shrinking a DM device if there is outstanding I/O to the part of the device that is being removed. (Normally this doesn't happen - a filesystem would be resized first, for example.) The bug is that __clone_and_map() assumes dm_table_find_target() always returns a valid pointer. It may fail if a bio arrives from the block layer but its target sector is no longer included in the DM btree. This patch appends an empty entry to table->targets[] which will be returned by a lookup beyond the end of the device. After calling dm_table_find_target(), __clone_and_map() and target_message() check for this condition using dm_target_is_valid(). Sample test script to trigger oops: 20 December 2007, 17:32:08 UTC

2c3b20e Arjan van de Ven 20 December 2007, 14:01:17 UTC debug: add end-of-oops marker Right now it's nearly impossible for parsers that collect kernel crashes from logs or emails (such as www.kerneloops.org) to detect the end-of-oops condition. In addition, it's not currently possible to detect whether or not 2 oopses that look alike are actually the same oops reported twice, or are truly two unique oopses. This patch adds an end-of-oops marker, and makes the end marker include a very simple 64-bit random ID to be able to detect duplicate reports. Normally, this ID is calculated as a late_initcall() (in the hope that at that time there is enough entropy to get a unique enough ID); however for early oopses the oops_exit() function needs to generate the ID on the fly. We do this all at the _end_ of an oops printout, so this does not impact our ability to get the most important portions of a crash out to the console first. [ Sidenote: the already existing oopses-since-bootup counter we print during crashes serves as the differentiator between multiple oopses that trigger during the same bootup. ] Tested on 32-bit and 64-bit x86. Artificially injected very early crashes as well, as expected they result in this constant ID after multiple bootups: ---[ end trace ca143223eefdc828 ]--- ---[ end trace ca143223eefdc828 ]--- because the random pools are still all zero. But it all still works fine and causes no additional problems (which is the main goal of instrumentation code).

The culprit turns out to be filesystems (cough ext3 with data=journal cough) that re-dirty the page when the "->invalidatepage()" callback is called. Fix it up by doing a final dirty page accounting check when we actually remove the page from the page cache.

It kept dying because set_thread_area was returning -ESRCH (bugs.debian.org/451939). I instrumented arch/ia64/ia32/sys_ia32.c:get_free_idx() and ended up seeing output like [pid] idx desc->a desc->b ----------------------------- [2710] 0 -> c6b0ffff 40dff31b [2710] 1 -> 0 0 [2710] 2 -> 0 0 [2710] 0 -> c6b0ffff 40dff31b [2710] 1 -> c6b0ffff 40dff31b [2710] 2 -> 0 0 [2711] 0 -> c6b0ffff 40dff31b [2711] 1 -> c6b0ffff 40dff31b [2711] 2 -> 48c0ffff 40dff317 which suggested to me that TLS pointers were surviving exec() calls, leading to GDT pointers filling up and the eventual failure of get_free_idx().

aec103b de Dinechin, Christophe (Integrity VM) 13 December 2007, 15:03:07 UTC [IA64] Avoid unnecessary TLB flushes when allocating memory Improve performance of memory allocations on ia64 by avoiding a global TLB purge to purge a single page from the file cache. This happens whenever we evict a page from the buffer cache to make room for some other allocation. Test case: Run 'find /usr -type f | xargs cat > /dev/null' in the background to fill the buffer cache, then run something that uses memory, e.g. 'gmake -j50 install'. Instrumentation showed that the number of global TLB purges went from a few millions down to about 170 over a 12 hours run of the above. The performance impact is particularly noticeable under virtualization, because a virtual TLB is generally both larger and slower to purge than a physical one.

4aae070 Ingo Molnar 18 December 2007, 17:05:58 UTC x86: fix "Kernel panic - not syncing: IO-APIC + timer doesn't work!" this is the tale of a full day spent debugging an ancient but elusive bug. after booting up thousands of random .config kernels, i finally happened to generate a .config that produced the following rare bootup failure on 32-bit x86: | ..TIMER: vector=0x31 apic1=0 pin1=2 apic2=-1 pin2=-1 | ..MP-BIOS bug: 8254 timer not connected to IO-APIC | ...trying to set up timer (IRQ0) through the 8259A ... failed. | ...trying to set up timer as Virtual Wire IRQ... failed. | ...trying to set up timer as ExtINT IRQ... failed :(. | Kernel panic - not syncing: IO-APIC + timer doesn't work! Boot with apic=debug | and send a report. Then try booting with the 'noapic' option this bug has been reported many times during the years, but it was never reproduced nor fixed. the bug that i hit was extremely sensitive to .config details. First i did a .config-bisection - suspecting some .config detail. That led to CONFIG_X86_MCE: enabling X86_MCE magically made the bug disappear and the system would boot up just fine. Debugging my way through the MCE code ended up identifying two unlikely candidates: the thing that made a real difference to the hang was that X86_MCE did two printks: Intel machine check architecture supported. Intel machine check reporting enabled on CPU#1. Adding the same printks to a !CONFIG_X86_MCE kernel made the bug go away! this left timing as the main suspect: i experimented with adding various udelay()s to the arch/x86/kernel/io_apic_32.c:check_timer() function, and the race window turned out to be narrower than 30 microseconds (!). That made debugging especially funny, debugging without having printk ability before the bug hits is ... interesting ;-) eventually i started suspecting IRQ activities - those are pretty much the only thing that happen this early during bootup and have the timescale of a few dozen microseconds. Also, check_timer() changes the IRQ hardware in various creative ways, so the main candidate became IRQ0 interaction. i've added a counter to track timer irqs (on which core they arrived, at what exact time, etc.) and found that no timer IRQ would arrive after the bug condition hits - even if we re-enable IRQ0 and re-initialize the i8259A, but that we'd get a small number of timer irqs right around the time when we call the check_timer() function. Eventually i got the following backtrace triggered from debug code in the timer interrupt: ...trying to set up timer as Virtual Wire IRQ... failed. ...trying to set up timer as ExtINT IRQ... Pid: 1, comm: swapper Not tainted (2.6.24-rc5 #57) EIP: 0060:[<c044d57e>] EFLAGS: 00000246 CPU: 0 EIP is at _spin_unlock_irqrestore+0x5/0x1c EAX: c0634178 EBX: 00000000 ECX: c4947d63 EDX: 00000246 ESI: 00000002 EDI: 00010031 EBP: c04e0f2e ESP: f7c41df4 DS: 007b ES: 007b FS: 00d8 GS: 0000 SS: 0068 CR0: 8005003b CR2: ffe04000 CR3: 00630000 CR4: 000006d0 DR0: 00000000 DR1: 00000000 DR2: 00000000 DR3: 00000000 DR6: ffff0ff0 DR7: 00000400 [<c05f5784>] setup_IO_APIC+0x9c3/0xc5c the spin_unlock() was called from init_8259A(). Wait ... we have an IRQ0 entry while we are in the middle of setting up the local APIC, the i8259A and the PIT?? That is certainly not how it's supposed to work! check_timer() was supposed to be called with irqs turned off - but this eroded away sometime in the past. This code would still work most of the time because this code runs very quickly, but just the right timing conditions are present and IRQ0 hits in this small, ~30 usecs window, timer irqs stop and the system does not boot up. Also, given how early this is during bootup, the hang is very deterministic - but it would only occur on certain machines (and certain configs). The fix was quite simple: disable/restore interrupts properly in this function. With that in place the test-system now boots up just fine. (64-bit x86 io_apic_64.c had the same bug.) Phew!

971e5b3 Steven Rostedt 18 December 2007, 17:05:58 UTC genirq: revert lazy irq disable for simple irqs In commit 76d2160147f43f982dfe881404cfde9fd0a9da21 lazy irq disabling was implemented, and the simple irq handler had a masking set to it. Remy Bohmer discovered that some devices in the ARM architecture would trigger the mask, but never unmask it. His patch to do the unmasking was questioned by Russell King about masking simple irqs to begin with. Looking further, it was discovered that the problems Remy was seeing was due to improper use of the simple handler by devices, and he later submitted patches to fix those. But the issue that was uncovered was that the simple handler should never mask. This patch reverts the masking in the simple handler.

cdc6f27 Thomas Gleixner 18 December 2007, 17:05:58 UTC clockevents: fix reprogramming decision in oneshot broadcast Resolve the following regression of a choppy, almost unusable laptop: http://lkml.org/lkml/2007/12/7/299 http://bugzilla.kernel.org/show_bug.cgi?id=9525 A previous version of the code did the reprogramming of the broadcast device in the return from idle code. This was removed, but the logic in tick_handle_oneshot_broadcast() was kept the same. When a broadcast interrupt happens we signal the expiry to all CPUs which have an expired event. If none of the CPUs has an expired event, which can happen in dyntick mode, then we reprogram the broadcast device. We do not reprogram otherwise, but this is only correct if all CPUs, which are in the idle broadcast state have been woken up. The code ignores, that there might be pending not yet expired events on other CPUs, which are in the idle broadcast state. So the delivery of those events can be delayed for quite a time. Change the tick_handle_oneshot_broadcast() function to check for CPUs, which are in broadcast state and are not woken up by the current event, and enforce the rearming of the broadcast device for those CPUs.

The result is that it now shows up as thread wchan (which also affects /proc/profile stats). The following simple patch fixes this by properly marking rwsem_down_failed_common() as a __sched function. Also in this patch, which is up for discussion, marks down_read() and down_write() proper as __sched. For profiling, it is pretty much useless to know that a semaphore is beig help - it is necessary to know _which_ one. By going up another frame on the stack, the information becomes much more useful. In summary, the below change to lib/rwsem.c should be applied; the changes to kernel/rwsem.c could be applied if other kernel hackers agree with my proposal that down_read()/down_write() in the profile is not enough.

The same code is used when we truncate the file size down. In this case we need to wait for any pending I/Os for dirty pages beyond the new eof. For the last close case we are not changing the file size and therefore do not need to wait for any I/Os to complete. This fixes a performance bottleneck where writes into the page cache and cache flushes can become mutually exclusive.

d1c3fb1 Nishanth Aravamudan 18 December 2007, 00:20:12 UTC hugetlb: introduce nr_overcommit_hugepages sysctl hugetlb: introduce nr_overcommit_hugepages sysctl While examining the code to support /proc/sys/vm/hugetlb_dynamic_pool, I became convinced that having a boolean sysctl was insufficient: 1) To support per-node control of hugepages, I have previously submitted patches to add a sysfs attribute related to nr_hugepages. However, with a boolean global value and per-mount quota enforcement constraining the dynamic pool, adding corresponding control of the dynamic pool on a per-node basis seems inconsistent to me. 2) Administration of the hugetlb dynamic pool with multiple hugetlbfs mount points is, arguably, more arduous than it needs to be. Each quota would need to be set separately, and the sum would need to be monitored. To ease the administration, and to help make the way for per-node control of the static & dynamic hugepage pool, I added a separate sysctl, nr_overcommit_hugepages. This value serves as a high watermark for the overall hugepage pool, while nr_hugepages serves as a low watermark. The boolean sysctl can then be removed, as the condition nr_overcommit_hugepages > 0 indicates the same administrative setting as hugetlb_dynamic_pool == 1 Quotas still serve as local enforcement of the size of the pool on a per-mount basis. A few caveats: 1) There is a race whereby the global surplus huge page counter is incremented before a hugepage has allocated. Another process could then try grow the pool, and fail to convert a surplus huge page to a normal huge page and instead allocate a fresh huge page. I believe this is benign, as no memory is leaked (the actual pages are still tracked correctly) and the counters won't go out of sync. 2) Shrinking the static pool while a surplus is in effect will allow the number of surplus huge pages to exceed the overcommit value. As long as this condition holds, however, no more surplus huge pages will be allowed on the system until one of the two sysctls are increased sufficiently, or the surplus huge pages go out of use and are freed. Successfully tested on x86_64 with the current libhugetlbfs snapshot, modified to use the new sysctl.
