[kamailio/kamailio] topos module producing invalid SIP message (missing Via header) when handling 200 OK to OPTIONS request (#1350)
by George Diamantopoulos 20 Oct '21

20 Oct '21

Hello all, I've come across the following issue with topos on Kamailio 5.1.0-rc2. ### Description Kamailio acts as a proxy for asterisk instances residing in a private IP range. Asterisk's peers are configured with their public IP address or hostname, but asterisk will dispatch requests to them to kamailio instead (because kamailio's IP is set in outboundproxy option in peer definition). This works fine for INVITEs, but if qualify=yes is set for the peer, asterisk will send out OPTIONs to monitor these peers. If the topos module is loaded, 200 OK replies to these OPTIONs will be malformed when forwarded from kamailio to asterisk (no Via header present). Disabling the topos module will resolve this. ### Troubleshooting #### Reproduction Configure a peer in asterisk with outboundproxy option set to kamailio's IP address. Set qualify=yes. Adjust kamailio's default configuration so that OPTIONs to other hosts besides itself are routed. Change the following section in request_route: ``` if ($rU==$null) { # request with no Username in RURI sl_send_reply("484","Address Incomplete"); exit; } ``` to: ``` if ( ($rU==$null) && !(is_method("OPTIONS")) ) { # request with no Username in RURI sl_send_reply("484","Address Incomplete"); exit; } # Permit asterisk's monitoring using options if(is_method("OPTIONS") && uri!=myself) { route(RELAY); } ``` Enable and configure the topos module with database. #### SIP Traffic asterisk:5060 -> kamailio:5060 ``` OPTIONS sip:peer.domain.tld SIP/2.0 Via: SIP/2.0/UDP asterisk:5060;branch=z9hG4bK460330cf;rport Max-Forwards: 70 From: "asterisk" <sip:asterisk@domain.tld>;tag=as690c2406 To: <sip:peer.domain.tld> Contact: <sip:asterisk@asterisk:5060> Call-ID: 6548f43b2d8740122186bb0c6e72ac78(a)domain.tld CSeq: 102 OPTIONS User-Agent: myUA Date: Sun, 03 Dec 2017 00:39:38 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer Content-Length: 0 ``` kamailio:5060 -> peer:5060 ``` OPTIONS sip:peer.domain.tld SIP/2.0 Via: SIP/2.0/UDP kamailio:5060;branch=z9hG4bK460330cf;rport Max-Forwards: 69 From: "asterisk" <sip:asterisk@domain.tld>;tag=as690c2406 To: <sip:peer.domain.tld> Contact: <sip:asterisk@asterisk:5060> Call-ID: 6548f43b2d8740122186bb0c6e72ac78(a)domain.tld CSeq: 102 OPTIONS User-Agent: myUA Date: Sun, 03 Dec 2017 00:39:38 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer Content-Length: 0 ``` peer:5060 -> kamailio:5060 ``` SIP/2.0 200 OK Via: SIP/2.0/UDP kamailio;branch=z9hG4bKda8d.cc03bd2def8ad36e8c43f61ab31a636f.0;received=kamailio;rport=5060 From: "asterisk" <sip:asterisk@domain.tld>;tag=as690c2406 To: <sip:peer.domain.tld>;tag=as472874ee Call-ID: 6548f43b2d8740122186bb0c6e72ac78(a)domain.tld CSeq: 102 OPTIONS Server: myUA Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer Contact: <sip:peer:5060> Accept: application/sdp Content-Length: 0 ``` **kamailio:5060 -> asterisk:5060: Missing Via Header** ``` SIP/2.0 200 OK From: "asterisk" <sip:asterisk@domain.tld>;tag=as690c2406 To: <sip:peer.domain.tld>;tag=as472874ee Call-ID: 6548f43b2d8740122186bb0c6e72ac78(a)domain.tld CSeq: 102 OPTIONS Server: myUA Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer Contact: <sip:peer:5060> Accept: application/sdp Content-Length: 0 ``` ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.1.0-rc2 (x86_64/linux) flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled with gcc 6.3.0 ``` * **Operating System**: ``` Debian 9.1 ``` * **Other pertinent configuration information**: This kamailio box has several network interfaces. mhomed is not used, instead force_send_socket is called where necessary.

[kamailio/kamailio] Expand the list of required default 3rd party libraries for Kamailio (#969)
by Olle E. Johansson 02 Dec '20

02 Dec '20

(from devmeeting #Fosdem) - adding new dependencies as core dependencies - Curl - libssl - uuid - libunistring - libxml2 Any other candidates? They have to be libraries that are commonly installed on most Linux/Unix system. This would mean that a lot of more modules will be built by default, like TLS, HTTP_CLIENT, WEBSOCKET. We may also look over the names of the packages/groups for the build system and linux distros -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] topos module seems to break re-SUBSCRIBE routing to downstream destinations (#1724)
by George Diamantopoulos 18 Nov '20

18 Nov '20

### Description Kamailio seems to fail to properly route in-dialog SUBSCRIBE with the topos module enabled. In this configuration, SUBSCRIBEs are expected to be delivered to a downstream UAS, an asterisk instance in the internal network. record_route() is executed for all initial requests, including SUBSCRIBEs. Routing is performed correctly with the topos module disabled, no other modifications were needed.  ### Troubleshooting I haven't been able to work around this issue in any other way other than disabling the topos module. #### Reproduction The configuration used is a heavily modified version of the example configuration file, but the handling of SUBSCRIBEs is generally simple. The initial SUBSCRIBE is subject to some tests, the R-URI is edited and dispatched to a farm of asterisk servers based on some criteria. Record Routing is enforced, so subsequent in-dialog re-SUBSCRIBEs are expected to be routed with loose_route(), which doesn't seem to handle things properly.  #### Debugging Data I'm attaching kamailio logs with debug=4, cfg_trace  #### Log Messages See attachments  #### SIP Traffic Please see: https://www.cloudshark.org/captures/d2643aae7f2a  ### Possible Solutions Using topoh instead for topos, but unfortunately this will break communication for other reasons (messages too large/UDP fragmentation for some peers). ### Additional Information * **Kamailio Version** Tried with kamailio 5.1.6 and kamailio 5.3.0-dev0 deb.kamailio.org repositories were used to acquire binaries for both versions * **Operating System**: Debian Stretch  [resubscribe.log](https://github.com/kamailio/kamailio/files/2586440/resubsc… -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Active dialog stats stays static on a passive kamailio node that replicates dialogs via DMQ (#1692)
by Joel Serrano 11 Aug '20

11 Aug '20

### Description In a setup with 2 kamailios in active/passive with a virtual IP that failovers between them: sbc01 (active) is handling calls. sbc02 (passive) is started, and does an initial dialog sync via DMQ ``` root@sbc01:~# kamctl rpc stats.get_statistics all | grep dialog "dialog:active_dialogs = 39", "dialog:early_dialogs = 2", "dialog:expired_dialogs = 0", "dialog:failed_dialogs = 583", "dialog:processed_dialogs = 2527", root@sbc01:~# ``` ``` root@sbc02:/etc/kamailio# kamctl rpc stats.get_statistics all | grep dialog "dialog:active_dialogs = 39", "dialog:early_dialogs = 0", "dialog:expired_dialogs = 0", "dialog:failed_dialogs = 0", "dialog:processed_dialogs = 0", root@sbc02:/etc/kamailio# ``` >From that point onwards, as long as sbc01 stays as active, sbc02 stays as passive, and no restarts occur anywhere, the values for `dialog` metrics in sbc02 will not change and remain as they are, in the previous example, active_dialogs would remain as 39. ### Troubleshooting This was discovered during some tests from #1591 #### Reproduction Setup 2 kamailio instances that replicate dialogs via DMQ. 1- On Kamailio1 put some traffic to have some active dialogs (must call `dlg_manage()` in routing script for these test calls) 2- Start Kamailio2 3- Compare output of: `kamcmd stats.get_statistics dialog:` on both nodes. 4- Alter the amount of active dialogs on Kamailio1 (either end some or create new ones). 5- Repeat step 3. Kamailio1 --> Step5 will have different values from Step3. Kamailio2 --> Step5 will have exactly the same values from Step3. ### Possible Solutions `dialog:active_dialogs` should remain as 0 on Kamailio2, as technically there are no dialogs being handled by that server, it only has information of replicated dialogs and those stats are available in the `dlg.stats_active` metric. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` # kamailio -V version: kamailio 5.2.0-pre1 (x86_64/linux) 2ecf60-dirty flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144 MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 2ecf60 -dirty compiled with gcc 6.3.0 ``` * **Operating System**:  ``` root@sbc02:~# lsb_release -a No LSB modules are available.
