From 85645bab57bfc6b0b43bb96a301c4ef83925c07d Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Sun, 22 Mar 2015 10:22:24 -0700 Subject: ipv4: dccp: handle ICMP messages on DCCP_NEW_SYN_RECV request sockets dccp_v4_err() can restrict lookups to ehash table, and not to listeners. Note this patch creates the infrastructure, but this means that ICMP messages for request sockets are ignored until complete conversion. New dccp_req_err() helper is exported so that we can use it in IPv6 in following patch. Signed-off-by: Eric Dumazet Signed-off-by: David S.
