-Subject: [PATCH] Do not call gpm_grab_sock() twice
-
-In the gpm_get_ctx() call, we unnecessarily call gpm_grab_sock() which
-would cause the lock to be held by one thread and never released.  We
-already call gpm_grab_sock() as the first thing after gpm_get_ctx() in
-gpm_make_call(), plus gpm_make_call() properly releases the socket
-once done.
-
-This corrects the deadlock fix in
-461a5fa9f91a2753ebeef6323a64239c35e2f250, which incorrectly released
-the lock we wanted to grab.  This caused the socket to not be locked
-to our thread.  Another thread could come along and change the global
-ctx while we were still using the socket from another thread, causing
-concurrency issues as only one request can be in flight on any given
-socket at the same time.
-
-In special cases where the "thread" uid/gid changes (like in
-rpc.gssd), we end up closing the socket while we are still waiting for
-an answer from the server, causing additional issues and confusion.
