Subject: [PATCH AUTOSEL 5.4 05/16] selinux: use correct type for context length
Date: Mon, 28 Mar 2022 07:23:34 -0400 [thread overview]
Message-ID: <20220328112345.1556601-5-sashal@kernel.org> (raw)
In-Reply-To: <20220328112345.1556601-1-sashal@kernel.org>
From: Christian Göttsche <cgzones@googlemail.com>
[ Upstream commit b97df7c098c531010e445da88d02b7bf7bf59ef6 ]
security_sid_to_context() expects a pointer to an u32 as the address
where to store the length of the computed context.
Reported by sparse:
security/selinux/xfrm.c:359:39: warning: incorrect type in arg 4
(different signedness)
security/selinux/xfrm.c:359:39: expected unsigned int
[usertype] *scontext_len
security/selinux/xfrm.c:359:39: got int *
