Linus Torvalds fbfd1d2862 ipc: fix double sem unlock in semctl error path ... Fix another ipc locking buglet introduced by the scalability patches: when semctl_down() was changed to delay the semaphore locking, one error path for security_sem_semctl() went through the semaphore unlock logic even though the semaphore had never been locked. Introduced by commit 16df3674ef ("ipc,sem: do not hold ipc lock more than necessary") Acked-by: Davidlohr Bueso <davidlohr.bueso@hp.com> Cc: Rik van Riel <riel@redhat.com> Cc: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2013-05-04 17:19:59 -07:00
