Subject[BUG]: posix timer: slab error 'double free'
Hi everyone:

A posix timer race condition is found in current kernel source tree.
Jeremy has actually
reported the same problem.

I write a simple stress test program for posix timer subsystem, to
reproduce the problem in the lastest mainline kernel.
My test program creates 200 threads, and each thread does the following job:

while (1) {
timer_create()
timer_settime()

sleep a while

timer_delete()
}
Please see my test program in the attachemnt "posix_timer_test.c". You
can compile my test program via the following command line:

gcc -static -o posix_timer_test.c posix_timer_test.c -lrt -lpthread

For my testing environment, you can refer to the three attachment files:
"dmesg.txt", "cpuinfo.txt", "config.txt"

In the pristine Linux-2.6.23-rc3, we get the following oops message:

slab error in cache_alloc_debugcheck_after(): cache `sigqueue': double

Kernel panic - not syncing: Fatal exception in interrupt
And I also apply the four patches from Oleg Nesterov from lkml:

http://lkm.org/lkml/2007/8/12/193
http://lkm.org/lkml/2007/8/12/194
http://lkm.org/lkml/2007/8/12/195
http://lkm.org/lkml/2007/8/12/196

After about ten hours, the kernel still panic. Here is its oops message:
