  • 54cdfdb47   [PATCH] hrtimers: add high resolution timer support ... Browse Code »

    Implement high resolution timers on top of the hrtimers infrastructure and the
    clockevents / tick-management framework. This provides accurate timers for
    all hrtimer subsystem users.

  • c9cb2e3d7   [PATCH] hrtimers: namespace and enum cleanup ... Browse Code »

    - hrtimers did not use the hrtimer_restart enum and relied on the implict
    int representation. Fix the prototypes and the functions using the enums.
    - Use seperate name spaces for the enumerations
    - Convert hrtimer_restart macro to inline function
    - Add comments

    No functional changes.

  • e18b890bb   [PATCH] slab: remove kmem_cache_t ... Browse Code »

    Replace all uses of kmem_cache_t with struct kmem_cache.

    The patch was generated using the following script:

    #!/bin/sh
    #
    # Replace one string by another in all the kernel sources.
    #

    set -e

    for file in `find * -name "*.c" -o -name "*.h"|xargs grep -l $1`; do
    quilt add $file
    sed -e "1,\$s/$1/$2/g" $file >/tmp/$$
    mv /tmp/$$ $file
    quilt refresh
    done

    The script was run like this

    sh replace kmem_cache_t "struct kmem_cache"

  • 1711ef386   [PATCH] posix-timers: Fix clock_nanosleep() doesn't return the remaining time in compatibility mode ... Browse Code »

    The clock_nanosleep() function does not return the time remaining when the
    sleep is interrupted by a signal.

    This patch creates a new call out, compat_clock_nanosleep_restart(), which
    handles returning the remaining time after a sleep is interrupted. This
    patch revives clock_nanosleep_restart(). It is now accessed via the new
    call out. The compat_clock_nanosleep_restart() is used for compatibility
    access.

    Since this is implemented in compatibility mode the normal path is
    virtually unaffected - no real performance impact.

  • 25f407f0b   [PATCH] Call exit_itimers from do_exit, not __exit_signal ... Browse Code »

    When I originally moved exit_itimers into __exit_signal, that was the only
    place where we could reliably know it was the last thread in the group
    dying, without races. Since then we've gotten the signal_struct.live
    counter, and do_exit can reliably do group-wide cleanup work.

    This patch moves the call to do_exit, where it's made without locks. This
    avoids the deadlock issues that the old __exit_signal code's comment talks
    about, and the one that Oleg found recently with process CPU timers.

    [ This replaces e03d13e985d48ac4885382c9e3b1510c78bd047f, which is why
    it was just reverted. ]

  • e752dd6cc   [PATCH] fix send_sigqueue() vs thread exit race ... Browse Code »

    posix_timer_event() first checks that the thread (SIGEV_THREAD_ID case)
    does not have PF_EXITING flag, then it calls send_sigqueue() which locks
    task list. But if the thread exits in between the kernel will oops
    (->sighand == NULL after __exit_sighand).

    This patch moves the PF_EXITING check into the send_sigqueue(), it must be
    done atomically under tasklist_lock. When send_sigqueue() detects exiting
    thread it returns -1. In that case posix_timer_event will send the signal
    to thread group.

    Also, this patch fixes task_struct use-after-free in posix_timer_event.

  • 78fa74a23   [PATCH] posix timers: fix normalization problem ... Browse Code »

    (We found this (after a customer complained) and it is in the kernel.org
    kernel. Seems that for CLOCK_MONOTONIC absolute timers and clock_nanosleep
    calls both the request time and wall_to_monotonic are subtracted prior to
    the normalize resulting in an overflow in the existing normalize test.
    This causes the result to be shifted ~4 seconds ahead instead of ~2 seconds
    back in time.)

    The normalize code in posix-timers.c fails when the tv_nsec member is ~1.2
    seconds negative. This can happen on absolute timers (and
    clock_nanosleeps) requested on CLOCK_MONOTONIC (both the request time and
    wall_to_monotonic are subtracted resulting in the possibility of a number
    close to -2 seconds.)

    This fix uses the set_normalized_timespec() (which does not have an
    overflow problem) to fix the problem and as a side effect makes the code
    cleaner.

  • f972be33c   [PATCH] posix-timers: use try_to_del_timer_sync() ... Browse Code »

    sys_timer_settime/sys_timer_delete needs to delete k_itimer->real.timer
    synchronously while holding ->it_lock, which is also locked in
    posix_timer_fn.

    This patch removes timer_active/set_timer_inactive which plays with
    timer_list's internals in favour of using try_to_del_timer_sync(), which
    was introduced in the previous patch.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
