* ctdb-locking: Fork lock helper with vfork_with_logging()Martin Schwenke2014-09-122-41/+35
| | | | | | | | | | | | Otherwise errors printed by the lock helper get lost. lock_helper_args() no longer adds the program name to the list of arguments, since vfork_with_logging() does that. Update the lock helper to handle the extra log_fd parameter passed by vfork_with_logging() and send stdout/stderr there.

* ctdb-locking: Add argc parameter to lock_helper_args()Martin Schwenke2014-09-121-12/+16
| | | | | | | | | | | To make this sane, also add an argv parameter and change the return type to bool. Anticipating a subsequent change, make the type of argv match what is needed by vfork_with_logging() and cast it when passing to execv(). This also means changing the type of the name member of struct db_namelist. Signed-off-by: Martin Schwenke <martin@meltin.net> Reviewed-by: Amitay Isaacs <amitay@gmail.com>
* ctdb-locking: Set real-time priority for lock helpersAmitay Isaacs2014-09-111-0/+2
| | | | | | | | | | | | | | | | | To avoid lock helper starvation when userspace robust mutexes are enabled. Commit 6f072f85a138f595494dbec137bcf23d1e666acc removed reset_scheduler(), to avoid resetting scheduler priority. However, that is not sufficient because of commit 1be8564e553ce044426dbe7b3987edf514832940, which sets SCHED_RESET_ON_FORK flag. With SCHED_RESET_ON_FORK, all CTDB child processes will automatically have normal scheduling priority.
