From fc9f868e5682355315f4a32ad927cde846e056ab Mon Sep 17 00:00:00 2001 From: Sasha Levin Date: Fri, 23 Jan 2015 20:47:00 -0500 Subject: 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.
