From: James Morris
Date: Wed Oct 18 2017 - 22:24:34 EST
This includes a fix for the capabilities code from Colin King, and a set
of further fixes for the Keys subsystem. From David:
"(1) Fix a bunch of places where kernel drivers may access revoked user-type
keys and don't do it correctly.
(2) Fix some ecryptfs bits.
(3) Fix big_key to require CONFIG_CRYPTO.
(4) Fix a couple of bugs in the asymmetric key type.
(5) Fix a race between updating and finding negative keys.
(6) Prevent add_key() from updating uninstantiated keys.
(7) Make loading of key flags and expiry time atomic when not holding
locks."
Please pull!
