From e547bc1eccf539b7403138d8ded913ffd2b7fd0d Mon Sep 17 00:00:00 2001 From: John Dykstra Date: Fri, 17 Jul 2009 09:23:22 +0000 Subject: tcp: Use correct peer adr when copying MD5 keys When the TCP connection handshake completes on the passive side, a variety of state must be set up in the "child" sock, including the key if MD5 authentication is being used. Fix TCP for both address families to label the key with the peer's destination address, rather than the address from the listening sock, which is usually the wildcard.
