From e3fa3aff0cb198e7c53d894f52146121d9592872 Mon Sep 17 00:00:00 2001 From: Lars Ellenberg Date: Mon, 28 Feb 2011 12:38:25 -0800 Subject: [PATCH] net: fix nla_policy_len to actually _iterate_ over the policy Currently nla_policy_len always returns n * NLA_HDRLEN: It loops, but does not advance it's iterator. NLA_UNSPEC == 0 does not contain a .len in any policy. Trivially fixed by adding p++. Signed-off-by: Lars Ellenberg Signed-off-by: David S.
