From de6becdc0844ff92b38ffd9f0c4db1d3de02835f Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 19 Apr 2011 21:30:51 +0000 Subject: sctp: fix to check the source address of COOKIE-ECHO chunk SCTP does not check whether the source address of COOKIE-ECHO chunk is the original address of INIT chunk or part of the any address parameters saved in COOKIE in CLOSED state. So even if the COOKIE-ECHO chunk is from any address but with correct COOKIE, the COOKIE-ECHO chunk still be accepted. If the COOKIE is not from a valid address, the assoc should not be established.
