Subject: [PATCH 4.4 18/49] KEYS: 64-bit MIPS needs to use compat_sys_keyctl for 32-bit userspace
Date: Sun, 14 Aug 2016 22:23:18 +0200	[thread overview]
Message-ID: <20160814202303.487889841@linuxfoundation.org> (raw)
In-Reply-To: <20160814202302.493206349@linuxfoundation.org>

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Howells <dhowells@redhat.com>

commit 20f06ed9f61a185c6dabd662c310bed6189470df upstream.

MIPS64 needs to use compat_sys_keyctl for 32-bit userspace rather than
calling sys_keyctl.  The latter will work in a lot of cases, thereby hiding
the issue.
