Jann Horn 0b9dc6c9f0 keys: safe concurrent user->{session,uid}_keyring access ... The current code can perform concurrent updates and reads on user->session_keyring and user->uid_keyring. Add a comment to struct user_struct to document the nontrivial locking semantics, and use READ_ONCE() for unlocked readers and smp_store_release() for writers to prevent memory ordering issues. Fixes: 69664cf16a ("keys: don't generate user and user session keyrings unless they're accessed") Signed-off-by: Jann Horn <jannh@google.com> Signed-off-by: James Morris <james.morris@microsoft.com>		2019-04-10 10:29:50 -07:00
