Subject: [PATCH 4.4 35/49] x86/syscalls/64: Add compat_sys_keyctl for 32-bit userspace
Date: Sun, 14 Aug 2016 22:23:35 +0200 [thread overview]
Message-ID: <20160814202304.454850545@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 f7d665627e103e82d34306c7d3f6f46f387c0d8b upstream.
x86_64 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.
