From b7058842c940ad2c08dd829b21e5c92ebe3b8758 Mon Sep 17 00:00:00 2001 From: David S. Miller Date: Wed, 30 Sep 2009 16:12:20 -0700 Subject: net: Make setsockopt() optlen be unsigned. This provides safety against negative optlen at the type level instead of depending upon (sometimes non-trivial) checks against this sprinkled all over the the place, in each and every implementation. Based upon work done by Arjan van de Ven and feedback from Linus Torvalds. Signed-off-by: David S.
