Subject: [PATCH 4.7 15/41] KEYS: 64-bit MIPS needs to use compat_sys_keyctl for 32-bit userspace
Date: Sun, 14 Aug 2016 22:38:41 +0200 [thread overview]
Message-ID: <20160814202532.813199627@linuxfoundation.org> (raw)
In-Reply-To: <20160814202531.818402015@linuxfoundation.org>
4.7-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.
