[PATCH 0/3] ucounts: misc fixes

From: Eric W. Biederman
Date: Mon Oct 18 2021 - 13:21:22 EST



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
