Subject: [PATCH 0/3] ucounts: misc fixes
Date: Mon, 18 Oct 2021 12:21:07 -0500 [thread overview]
Message-ID: <871r4itfjw.fsf_-_@disp2133> (raw)
In-Reply-To: <87fssytizw.fsf_-_@disp2133> (Eric W. Biederman's message of "Mon, 18 Oct 2021 11:06:43 -0500")
While digging into the previous ucount kernel crashes I found some minor
bugs in the ucount code. When hit these bugs all result in a ucount
either being counted in the wrong location or leak of a struct ucounts.
Nothing particularly serious but certainly things that should be fixed.
Eric W. Biederman (3):
ucounts: Pair inc_rlimit_ucounts with dec_rlimit_ucoutns in commit_creds
ucounts: Proper error handling in set_cred_ucounts
ucounts: Move get_ucounts from cred_alloc_blank to key_change_session_keyring
