From 39940a48c42441da5e7428483ac515e822d52b1d Mon Sep 17 00:00:00 2001 From: Al Viro Date: Mon, 20 Nov 2006 17:02:22 -0800 Subject: [SCTP] bug: sctp_assoc_lookup_laddr() is broken with ipv6. It expects (and gets) laddr with net-endian sin_port. And then it calls sctp_bind_addr_match(), which *does* care about port numbers in case of ipv6 and expects them to be host-endian.
