From mboxrd@z Thu Jan 1 00:00:00 1970 From: Florian Westphal Subject: [PATCH net] qfq: don't leak skb if kzalloc fails Date: Wed, 8 Jun 2016 14:31:33 +0200 Message-ID: <1465389093-29674-1-git-send-email-fw@strlen.de> Cc: Florian Westphal To: Return-path: Received: from Chamillionaire.breakpoint.cc ([80.244.247.6]:59233 "EHLO Chamillionaire.breakpoint.cc" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1425119AbcFHMbR (ORCPT ); Wed, 8 Jun 2016 08:31:17 -0400 Sender: netdev-owner@vger.kernel.org List-ID: When we need to create a new aggregate to enqueue the skb we need to kzalloc the new struct. If that fails we returned ENOBUFS without freeing the skb. Spotted during code review.
