We are probaly deleting the timer from run_posix_cpu_timers's 'firing'
local list_head while run_posix_cpu_timers() does list_for_each_safe.

Various bad things can happen, for example we can just delete this timer
so that list_for_each() will not notice it and run_posix_cpu_timers()
will not reset '->firing' flag. In that case,

....

if (timer->it.cpu.firing) {

sys_timer_settime() goes to 'retry:', calls posix_cpu_timer_set() again,

when we acquire the write lock in neigh_changeaddr.  The result is that
the timer may keep firing for quite a while until the entry reaches
NEIGH_FAILED.

It should be setting the nud_state straight away so that if the timer
has already fired it can simply exit once we relinquish the lock.

In fact, this whole function is simply duplicating the logic in
neigh_ifdown which in turn is already doing the right thing when
it comes to deleting timers and setting nud_state.

[PATCH] cpufreq: fix pending powernow timer stuck condition

AMD recently discovered that on some hardware, there is a race condition
possible when a C-state change request goes onto the bus at the same
time as a P-state change request.

Both requests happen, but the southbridge hardware only acknowledges the
C-state change.  The PowerNow! driver is then stuck in a loop, waiting
for the P-state change acknowledgement.  The driver eventually times
out, but can no longer perform P-state changes.

It turns out the solution is to resend the P-state change, which the
southbridge will acknowledge normally.

[PATCH] ppc64: Fix pages marked dirty abusively

While working on 64K pages, I found this little buglet in our
update_mmu_cache() implementation.

The code calls __hash_page() passing it an "access" parameter (the type
of access that triggers the hash) containing the bits _PAGE_RW and
_PAGE_USER of the linux PTE.  The latter is useless in this case and the
former is wrong.  In fact, if we have a writeable PTE and we pass
_PAGE_RW to hash_page(), it will set _PAGE_DIRTY (since we track dirty
that way, by hash faulting !dirty) which is not what we want.

In fact, the correct fix is to always pass 0. That means that only
read-only or already dirty read write PTEs will be preloaded. The
(hopefully rare) case of a non dirty read write PTE can't be preloaded
this way, it will have to fault in hash_page on the actual access.

This problem is starting to show up more and more as drivers turn to the

threads are now children of the kthread worker instead of modprobe, and
they inherit the PF_NOFREEZE flag.  This can cause problems during system

NeilBrown [Thu, 20 Oct 2005 04:23:47 +0000 (21:23 -0700)]
[PATCH] Three one-liners in md.c

The main problem fixes is that in certain situations stopping md arrays may
take longer than you expect, or may require multiple attempts.  This would
only happen when resync/recovery is happening.

This patch fixes three vaguely related bugs.

1/ The recent change to use kthreads got the setting of the
   process name wrong.  This fixes it.
2/ The recent change to use kthreads lost the ability for
   md threads to be signalled with SIG_KILL.  This restores that.
3/ There is a long standing bug in that if:
    - An array needs recovery (onto a hot-spare) and
    - The recovery is being blocked because some other array being
       recovered shares a physical device and
    - The recovery thread is killed with SIG_KILL
   Then the recovery will appear to have completed with no IO being
   done, which can cause data corruption.
   This patch makes sure that incomplete recovery will be treated as
   incomplete.

Note that any kernel affected by bug 2 will not suffer the problem of bug
3, as the signal can never be delivered.  Thus the current 2.6.14-rc
kernels are not susceptible to data corruption.  Note also that if arrays
are shutdown (with "mdadm -S" or "raidstop") then the problem doesn't
occur.  It only happens if a SIGKILL is independently delivered as done by
'init' when shutting down.

Oleg Nesterov reported an SMP deadlock.  If there is a running timer
tracking a different process's CPU time clock when the process owning
the timer exits, we deadlock on tasklist_lock in posix_cpu_timer_del via
exit_itimers.

That code was using tasklist_lock to check for a race with __exit_signal
being called on the timer-target task and clearing its ->signal.
However, there is actually no such race.  __exit_signal will have called
posix_cpu_timers_exit and posix_cpu_timers_exit_group before it does
that.  Those will clear those k_itimer's association with the dying
task, so posix_cpu_timer_del will return early and never reach the code
in question.

In addition, posix_cpu_timer_del called from exit_itimers during execve
or directly from timer_delete in the process owning the timer can race
with an exiting timer-target task to cause a double put on timer-target
task struct.  Make sure we always access cpu_timers lists with sighand
