Module: sip-router Branch: sr_3.0 Commit: 401f1b938365d5ca4fa6951fed71f8c9c13e1b49 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=401f1b9… Author: Andrei Pelinescu-Onciul <andrei(a)iptel.org> Committer: Andrei Pelinescu-Onciul <andrei(a)iptel.org> Date: Wed Aug 18 18:36:14 2010 +0200 tcp: fix double increment for the established stats The counter/stats for established TCP connections were incremented twice in the case of accept()-ed connections: once immediately after the accept() and another time after the first packet received or sent on the connection. Now they are incremented only after the first successful send or receive.
