* aio: bad AIO race in aio_complete() leads to process hangQuentin Barnes2008-03-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My group ran into a AIO process hang on a 2.6.24 kernel with the process sleeping indefinitely in io_getevents(2) waiting for the last wakeup to come and it never would. We ran the tests on x86_64 SMP. The hang only occurred on a Xeon box ("Clovertown") but not a Core2Duo ("Conroe"). On the Xeon, the L2 cache isn't shared between all eight processors, but is L2 is shared between between all two processors on the Core2Duo we use. My analysis of the hang is if you go down to the second while-loop in read_events(), what happens on processor #1: 1) add_wait_queue_exclusive() adds thread to ctx->wait 2) aio_read_evt() to check tail 3) if aio_read_evt() returned 0, call [io_]schedule() and sleep In aio_complete() with processor #2: A) info->tail = tail; B) waitqueue_active(&ctx->wait) C) if waitqueue_active() returned non-0, call wake_up() The way the code is written, step 1 must be seen by all other processors before processor 1 checks for pending events in step 2 (that were recorded by step A) and step A by processor 2 must be seen by all other processors (checked in step 2) before step B is done. The race I believed I was seeing is that steps 1 and 2 were effectively swapped due to the __list_add() being delayed by the L2 cache not shared by some of the other processors. Imagine: proc 2: just before step A proc 1, step 1: adds to ctx->wait, but is not visible by other processors yet proc 1, step 2: checks tail and sees no pending events proc 2, step A: updates tail proc 1, step 3: calls [io_]schedule() and sleeps proc 2, step B: checks ctx->wait, but sees no one waiting, skips wakeup so proc 1 sleeps indefinitely My patch adds a memory barrier between steps A and B. It ensures that the update in step 1 gets seen on processor 2 before continuing. If processor 1 was just before step 1, the memory barrier makes sure that step A (update tail) gets seen by the time processor 1 makes it to step 2 (check tail). Before the patch our AIO process would hang virtually 100% of the time. After the patch, we have yet to see the process ever hang.

| | | | | | | | | | | | | | | | | | | | | | | | The DMA_INTERRUPT async_tx is a NULL transfer, thus the BCR(count register) is 0. When the transfer started with a byte count of zero, the DMA controller will triger a PE(programming error) event and halt, not a normal interrupt. I add special codes for PE event and DMA_INTERRUPT async_tx testing.

| | | | | | | | | | | | | | | | | | | | | | | | Wakeup-buddy tasks are cache-hot - this makes it a bit harder for the load-balancer to tear them apart. (but it's still possible, if the load is sufficiently assymetric) Signed-off-by: Ingo Molnar <mingo@elte.hu>
| * | sched: improve affine wakeupsIngo Molnar2008-03-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | improve affine wakeups. Maintain the 'overlap' metric based on CFS's sum_exec_runtime - which means the amount of time a task executes after it wakes up some other task. Use the 'overlap' for the wakeup decisions: if the 'overlap' is short, it means there's strong workload coupling between this task and the woken up task. If the 'overlap' is large then the workload is decoupled and the scheduler will move them to separate CPUs more easily. ( Also slightly move the preempt_check within try_to_wake_up() - this has no effect on functionality but allows 'early wakeups' (for still-on-rq tasks) to be correctly accounted as well.)

* | IDE: Make taskfile interface more robust wrt unexpected end-of-commandLinus Torvalds2008-03-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we handle all the special commands using REQ_TYPE_ATA_TASKFILE rather than using the old REQ_TYPE_ATA_CMD model, we need to also emulate the lack of full taskfile data that comes with the old command model (ie when commands are generated with the HDIO_DRIVE_CMD ioctl rather than using the HDIO_DRIVE_TASK[FILE] ioctls). In particular, this means that we should handle command completion the more relaxed way that the old drive_cmd_intr() code did. It allows commands to finish early even if they don't use up all the data that we thought we had for them. This fixes a regression seen by Anders Eriksson where some SMART commands sent by smartd would cause a boot-time system hang on his machine because the IDE command handling code didn't realize that the command had completed.

| * slub page alloc fallback: Enable interrupts for GFP_WAIT.Christoph Lameter2008-03-17
| | | | | | | | | | | | | | | | | | | | | | The fallback path needs to enable interrupts like done for the other page allocator calls. This was not necessary with the alternate fast path since we handled irq enable/disable in the slow path. The regular fastpath handles irq enable/disable around calls to the slow path so we need to restore the proper status before calling the page allocator from the slowpath.

The reason for WARNING is because at the depth of idle handling code, some of the idle handlers disable interrupts, some times, while returning from the idle handler. After return, acpi_processor_idle and few other routines in the file did an unconditional local_irq_enable(). With LOCKDEP, enabling irq when it is already enabled generates the below WARNING. > > [ 0.593038] ------------[ cut here ]------------ > > [ 0.593267] WARNING: at kernel/lockdep.c:2035 trace_hardirqs_on+0xa0/0x115() > > [ 0.593596] Modules linked in: > > [ 0.593756] Pid: 0, comm: swapper Not tainted 2.6.25-rc5 #8 > > [ 0.594017] > > [ 0.594017] Call Trace: > > [ 0.594216] [<ffffffff80231663>] warn_on_slowpath+0x58/0x6b > > [ 0.594495] [<ffffffff80495966>] ? _spin_unlock_irqrestore+0x38/0x47 > > [ 0.594809] [<ffffffff80329a86>] ? acpi_os_release_lock+0x9/0xb > > [ 0.595103] [<ffffffff80337840>] ? acpi_set_register+0x161/0x173 > > [ 0.595401] [<ffffffff8034c8d4>] ? acpi_processor_idle+0x1de/0x546 > > [ 0.595706] [<ffffffff8020a23b>] ? default_idle+0x0/0x73 > > [ 0.595970] [<ffffffff8024fc0e>] trace_hardirqs_on+0xa0/0x115 > > [ 0.596049] [<ffffffff8034c6f6>] ? acpi_processor_idle+0x0/0x546 > > [ 0.596346] [<ffffffff8034c8d4>] acpi_processor_idle+0x1de/0x546 > > [ 0.596642] [<ffffffff8020a23b>] ? default_idle+0x0/0x73 > > [ 0.596912] [<ffffffff8034c6f6>] ? acpi_processor_idle+0x0/0x546 > > [ 0.597209] [<ffffffff8020a23b>] ? default_idle+0x0/0x73 > > [ 0.597472] [<ffffffff8020a355>] cpu_idle+0xa7/0xd1 > > [ 0.597717] [<ffffffff80485fa1>] rest_init+0x55/0x57 > > [ 0.597957] [<ffffffff8062fb49>] start_kernel+0x29d/0x2a8 > > [ 0.598215] [<ffffffff8062f1da>] _sinittext+0x1da/0x1e1 > > [ 0.598464] > > [ 0.598546] ---[ end trace 778e504de7e3b1e3 ]--- Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

The package template that is used to describe battery status is over-written with sane values when the battery is live. But when the batter is dead, a bogus reference in the template is used. In this case, Linux returns a fault, when instead it should simply return that it doesn't know the missing value. http://bugzilla.kernel.org/show_bug.cgi?id=8573 http://bugzilla.kernel.org/show_bug.cgi?id=10202 Signed-off-by: Alexey Starikovskiy <astarikovskiy@suse.de> Signed-off-by: Len Brown <len.brown@intel.com>
