Pull misc keyring updates from David Howells: "These are some miscellaneous keyrings fixes and improvements: - Fix a bunch of warnings from sparse, including missing RCU bits and kdoc-function argument mismatches - 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. - 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. - Improvement in lookup_user_key(). - Implement a keyctl to allow keyrings subsystem capabilities to be queried. The keyutils next branch has commits to make available, document and test the move-key and capabilities code: https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/keyutils.git/log They're currently on the 'next' branch" * tag 'keys-misc-20190619' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: keys: Add capability-checking keyctl function keys: Reuse keyring_index_key::desc_len in lookup_user_key() keys: Grant Link permission to possessers of request_key auth keys keys: Add a keyctl to move a key between keyrings keys: Hoist locking out of __key_link_begin() keys: Break bits out of key_unlink() keys: Change keyring_serialise_link_sem to a mutex keys: sparse: Fix kdoc mismatches keys: sparse: Fix incorrect RCU accesses keys: sparse: Fix key_fs[ug]id_changed()
