[0/7] keys: Miscellany

Message

David Howells May 22, 2019, 10:28 p.m. UTC

Here are some miscellaneous keyrings fixes and improvements intended for
the next merge window:

 (1) Fix a bunch of warnings from sparse, including missing RCU bits and
     kdoc-function argument mismatches

 (2) Implement a keyctl to allow a key to be moved from one keyring to
     another, with the option of prohibiting key replacement in the
     destination keyring.

 (3) Grant Link permission to possessors of request_key_auth tokens so that
     upcall servicing daemons can more easily arrange things such that only
     the necessary auth key is passed to the actual service program, and
     not all the auth keys a daemon might possesss.

The patches can be found on the following branch:
