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 kernel/cred.c | 9 ++++----- security/keys/process_keys.c | 8 ++++++++ 2 files changed, 12 insertions(+), 5 deletions(-) Eric Tested-by: Yu Zhao
