Outbound flow failure handling merged to master

by Hugh Waite

Hello, As you will see I have merged my branch back into master. These changes add a new event route [tm:branch-failure] to the tm module which is run when any failure response is received on a transaction. The event_route uses a new route type BRANCH_ROUTE which limits the functions that can be run in the route. The functions t_check_status(), t_next_contact_flow(), t_relay() and unregister() can be used in this route. A new pv $T_reply_ruid is accessible in this route which can be used to unregister a single contact entry. The following example route can be used on a registrar to handle failed or invalid flows: event_route[tm:branch-failure] { xlog("L_INFO", "event_route[tm:branch-failure]\n"); if (t_check_status("430|403")) { if (!unregister("location", "$tu", "$T_reply_ruid")) { xlog("L_WARN", "failed to unregister $tu with ruid $T_reply_ruid\n"); } if (!t_next_contact_flow()) { xlog("L_INFO", "No more flows\n"); } else { xlog("L_INFO", "Next flow\n"); t_relay(); } } } Any bugs, memory leaks etc. let me know!

[kamailio/kamailio] Possible bug with track_cseq_updates set in dialog (#789)

by scfcplummy

Hi, When setting "track_cseq_updates" in dialog module, the ReINVITE that should be initiated with uac_auth() is never sent. Without "track_cseq_updates" set to 0, the reINVITE does take place. In the log I can see dialog doing the cseq update: Sep 20 07:54:57 sbc /usr/local/sbin/kamailio[35746]: DEBUG: dialog [dlg_cseq.c:129]: dlg_cseq_update(): initiating cseq updates Sep 20 07:54:57 sbc /usr/local/sbin/kamailio[35746]: DEBUG: dialog [dlg_hash.c:690]: dlg_lookup(): ref dlg 0x7fc2b265f4f0 with 1 -> 2 Sep 20 07:54:57 sbc /usr/local/sbin/kamailio[35746]: DEBUG: dialog [dlg_hash.c:692]: dlg_lookup(): dialog id=4263 found on entry 1771 Sep 20 07:54:57 sbc /usr/local/sbin/kamailio[35746]: DEBUG: dialog [dlg_var.c:250]: print_lists(): Internal var-list ((nil)): Sep 20 07:54:57 sbc /usr/local/sbin/kamailio[35746]: DEBUG: dialog [dlg_var.c:260]: print_lists(): Dialog var-list (0x7fc2b265f2d8): Sep 20 07:54:57 sbc /usr/local/sbin/kamailio[35746]: DEBUG: dialog [dlg_var.c:262]: print_lists(): cseq_diff=1 (flags 1) Sep 20 07:54:57 sbc /usr/local/sbin/kamailio[35746]: DEBUG: dialog [dlg_cseq.c:176]: dlg_cseq_update(): adding auth cseq header value: 5136 but quickly followed by these errors: Sep 20 07:54:57 sbc /usr/local/sbin/kamailio[35746]: ERROR: <core> [msg_translator.c:417]: clen_builder(): no message body found (missing crlf?)

[kamailio/kamailio] uac_auth() function broken in 4.4.3 (#797)

by Sebastian Damm

We upgraded a system from 4.4.2 to 4.4.3 last week. After that, the uac_auth() function didn't do what it was supposed to do anymore. This is the failure route in the config file: ``` failure_route[TRUNKAUTH] { if (t_is_canceled()) { exit; } if ($T_reply_code == 401 or $T_reply_code == 407) { xlog("L_NOTICE", "[$pr:$si:$sp] [$cs $rm cid: $ci Status: $rs $rr F:$fU T:$tU R:$rU] Remote asked for authentication"); uac_auth(); t_relay(); exit; } } ``` In Kamailio 4.4.2 this works perfectly. In 4.4.3 when this code triggers, we get the following messages in our log: ``` Sep 23 12:25:41 eustatius /usr/sbin/kamailio[13249]: NOTICE: <script>: [udp:1.2.3.4:5060] [102 INVITE cid: asdasdalsjdalsdaskjdlak Status: <null> <null> F:11111111 T:00491234567890 R:01234567890] Remote asked for authentication Sep 23 12:25:41 eustatius /usr/sbin/kamailio[13249]: ERROR: <core> [msg_translator.c:417]: clen_builder(): no message body found (missing crlf?)
