From b225b884a18a1932db5414abd3ef94a45e4e348e Mon Sep 17 00:00:00 2001 From: Dave Johnson Date: Wed, 25 Jul 2007 19:49:29 -0400 Subject: SCTP: IPv4 mapped addr not returned in SCTPv6 accept() An accept() call on a SCTPv6 socket that returns due to connection of a IPv4 mapped peer will fill out the 'struct sockaddr' with a zero IPv6 address instead of the IPv4 mapped address of the peer. This is due to the v4mapped flag not getting copied into the new socket on accept() as well as a missing check for INET6 socket type in sctp_v4_to_sk_*addr().
