3.13.11-ckt17 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Sasha Levin <sasha.levin@xxxxxxxxxx> commit db27ebb111e9f69efece08e4cb6a34ff980f8896 upstream. 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. Signed-off-by: Sasha Levin <sasha.levin@xxxxxxxxxx> Signed-off-by: David S.
