Merge tag 'keys-fixes-20230321' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

Pull keyrings fixes from David Howells:

 - Fix request_key() so that it doesn't cache a looked up key on the
   current thread if that thread is a kernel thread.

   The cache is cleared during notify_resume - but that doesn't happen
   in kernel threads. This is causing cifs DNS keys to be
   un-invalidateable.

 - Fix a wrapper check in verify_pefile() to not round up the length.

 - Change asymmetric_keys code to log errors to make it easier for users
   to work out why failures occurred.
