Subject: [PATCH 0/1] cred: copy_process() should clear child->replacement_session_keyring
Date: Mon, 9 Apr 2012 21:03:23 +0200 [thread overview]
Message-ID: <20120409190323.GA14712@redhat.com> (raw)
Hello.
Looks trivial, but I do not know how to test and I don't understand
this code. David, please review ;)
Note: initially this was 1/2. The usage of >replacement_session_keyring
is racy, although the problem is minor. I think that instead of fixing
a lot of key_replace_session_keyring's callers in arch/ we can add the
simple abstraction layer and kill ->replacement_session_keyring. I'll
try to send the patches tomorrow.
Btw. exit_creds() does validate_creds(cred) right before put_cred(cred),
without alter_cred_subscribers() in between this looks unneeded?
Oleg.
