locks: fix checking of fcntl_setlease argument

2012-08-17T19:35:06Z

commit 0ec4f431eb56d633da3a55da67d5c4b88886ccc7 upstream. The only checks of the long argument passed to fcntl(fd,F_SETLEASE,.) are done after converting the long to an int. Thus some illegal values may be let through and cause problems in later code. [ They actually *don't* cause problems in mainline, as of Dave Jones's commit 8d657eb3b438 "Remove easily user-triggerable BUG from generic_setlease", but we should fix this anyway. And this patch will be necessary to fix real bugs on earlier kernels. ] Signed-off-by: J. Bruce Fields Signed-off-by: Linus Torvalds Signed-off-by: Paul Gortmaker

sched: Convert the only user of cond_resched_bkl to use cond_resched()

2009-07-18T13:51:45Z

fs/locks.c:flock_lock_file() is the only user of cond_resched_bkl() This helper doesn't do anything more than cond_resched(). The latter naming is enough to explain that we are rescheduling if needed. The bkl suffix suggests another semantics but it's actually a synonym of cond_resched().

lockd: call locks_release_private to cleanup per-filesystem state

2009-04-24T20:36:03Z

For every lock request lockd creates a new file_lock object in nlmsvc_setgrantargs() by copying the passed in file_lock with locks_copy_lock(). A filesystem can attach it's own lock_operations vector to the file_lock. It has to be cleaned up at the end of the file_lock's life. However, lockd doesn't do it today, yet it asserts in nlmclnt_release_lockargs() that the per-filesystem state is clean. This patch fixes it by exporting locks_release_private() and adding it to nlmsvc_freegrantargs(), to be symmetrical to creating a file_lock in nlmsvc_setgrantargs().
