Message-Id: <1422971760-8217-1-git-send-email-sasha.levin@oracle.com> Date: Tue, 3 Feb 2015 08:55:58 -0500 From: Sasha Levin <sasha.levin@...cle.com> To: linux-kernel@...r.kernel.org Cc: Sasha Levin <sasha.levin@...cle.com>, Chien Yen <chien.yen@...cle.com>, "David S. Miller" <davem@...emloft.net>, rds-devel@....oracle.com (moderated list:RDS - RELIABLE DA...), netdev@...r.kernel.org (open list:NETWORKING [GENERAL]) Subject: [PATCH] net: rds: use correct size for max unacked packets and bytes Max unacked packets/bytes is an int while sizeof(long) was used in the sysctl table. This means that when they were getting read we'd also leak kernel memory to userspace along with the timeout values.
