Subject: [PATCH BUGFIX ] ipv6: fix the bug of address check
Date: Mon, 17 May 2010 20:23:38 +0800	[thread overview]
Message-ID: <4BF1354A.3060003@cn.fujitsu.com> (raw)


If there are several IPv6 addresses with same hash value in hashlist,
and they are all not matched with addr argument.
In this case, ipv6_chk_addr() should return 0.

This bug is introduced by commit c2e21293c054817c42eb5fa9c613d2ad51954136
(title: ipv6: convert addrconf list to hlist).
