From f5895943d91b41b0368830cdb6eaffb8eda0f4c8 Mon Sep 17 00:00:00 2001 From: David Howells Date: Fri, 14 Mar 2014 17:44:49 +0000 Subject: KEYS: Move the flags representing required permission to linux/key.h Move the flags representing required permission to linux/key.h as the perm parameter of security_key_permission() is in terms of them - and not the permissions mask flags used in key->perm. Whilst we're at it: (1) Rename them to be KEY_NEED_xxx rather than KEY_xxx to avoid collisions with symbols in uapi/linux/input.h. (2) Don't use key_perm_t for a mask of required permissions, but rather limit it to the permissions mask attached to the key and arguments related directly to that.
