From 6b8d9117ccb4f81b1244aafa7bc70ef8fa45fc49 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.
