[PATCH] fix non-leader exec under ptrace

2006-04-17T20:16:06+00:00

This reverts most of commit 30e0fca6c1d7d26f3f2daa4dd2b12c51dadc778a.
It broke the case of non-leader MT exec when ptraced.
I think the bug it was intended to fix was already addressed by commit
788e05a67c343fa22f2ae1d3ca264e7f15c25eaf.

[PATCH] Fix suspend with traced tasks

2006-04-17T20:16:06+00:00

strace /bin/bash misbehaves after resume; this fixes it.

(akpm: it's scary calling refrigerator() in state TASK_TRACED, but it seems to
do the right thing).

[PATCH] RCU signal handling

2006-04-11T16:46:41+00:00

made this BUG_ON() unsafe. This code runs under ->siglock,
while switch_exec_pids() takes tasklist_lock.

[PATCH] sys_signal: initialize ->sa_mask

2006-02-10T00:17:36+00:00

Pointed out by Linus Torvalds.

sys_signal() forgets to initialize ->sa_mask.

( I suspect arch/ia64/ia32/ia32_signal.c:sys32_signal()
  also needs this fix )

[PATCH] Generic sys_rt_sigsuspend()

2006-01-19T03:20:29+00:00

The TIF_RESTORE_SIGMASK flag allows us to have a generic implementation of
sys_rt_sigsuspend() instead of duplicating it for each architecture.  This
provides such an implementation and makes arch/powerpc use it.

It also tidies up the ppc32 sys_sigsuspend() to use TIF_RESTORE_SIGMASK.

[PATCH] move capable() to capability.h

2006-01-12T02:42:13+00:00

- Move capable() from sched.h to capability.h;

- Use  where capable() is used
	(in include/, block/, ipc/, kernel/, a few drivers/,
	mm/, security/, & sound/;
	many more drivers/ to go)

[PATCH] remove unneeded sig->curr_target recalculation

2006-01-09T04:13:57+00:00

This patch removes unneeded sig->curr_target recalculation under 'if
(atomic_dec_and_test(&sig->count))' in __exit_signal().

When sig->count == 0 the signal can't be sent to this task and
next_thread(tsk) == tsk anyway.
