-Subject: libceph: don't set global_id until we get an auth ticket
-
-From: Ilya Dryomov <idryomov@gmail.com>
-
-commit 61ca49a9105faefa003b37542cebad8722f8ae22 upstream.
-
-With the introduction of enforcing mode, setting global_id as soon
-as we get it in the first MAuth reply will result in EACCES if the
-connection is reset before we get the second MAuth reply containing
-an auth ticket -- because on retry we would attempt to reclaim that
-global_id with no auth ticket at hand.
-
-Neither ceph_auth_client nor ceph_mon_client depend on global_id
-being set ealy, so just delay the setting until we get and process
-the second MAuth reply. While at it, complain if the monitor sends
-a zero global_id or changes our global_id as the session is likely
-to fail after that.
