Subject: [PATCH 4.14 34/38] sctp: fix return value check in __sctp_rcv_asconf_lookup
Date: Mon, 2 Aug 2021 15:44:56 +0200 [thread overview]
Message-ID: <20210802134335.904585164@linuxfoundation.org> (raw)
In-Reply-To: <20210802134334.835358048@linuxfoundation.org>
From: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com>
[ Upstream commit 557fb5862c9272ad9b21407afe1da8acfd9b53eb ]
As Ben Hutchings noticed, this check should have been inverted: the call
returns true in case of success.
Reported-by: Ben Hutchings <ben@decadent.org.uk>
Fixes: 0c5dc070ff3d ("sctp: validate from_addr_param return")
