Date: Fri, 23 Jan 2015 20:47:00 -0500 From: Sasha Levin <sasha.levin@...cle.com> To: linux-kernel@...r.kernel.org Cc: Sasha Levin <sasha.levin@...cle.com>, Arnaldo Carvalho de Melo <acme@...stprotocols.net>, "David S. Miller" <davem@...emloft.net>, netdev@...r.kernel.org (open list:NETWORKING [GENERAL]) Subject: [PATCH] net: llc: use correct size for sysctl timeout entries The timeout entries are sizeof(int) rather than sizeof(long), which means that when they were getting read we'd also leak kernel memory to userspace along with the timeout values.
