-Subject: [PATCH] SUNRPC: Ensure that gss_auth isn't freed before its upcall
- messages
-
-Fix a race in which the RPC client is shutting down while the
-gss daemon is processing a downcall. If the RPC client manages to
-shut down before the gss daemon is done, then the struct gss_auth
-used in gss_release_msg() may have already been freed.
