[kamailio/kamailio] New branch in DNS SRV failover is using wrong source socket (#2152)
by Thomas Lobker 03 Mar '20

03 Mar '20

### Description When relaying an `INVITE` from a Kamailio proxy to an interconnect we are using DNS SRV records for load-balancing and failover. The proxy is listening on both a private interface and a public interface with an rfc1918 (ie. `10.0.0.14`) and a public IP address (ie. `185.0.0.34`) respectively. The first branch (before DNS SRV failover) is working as expected. The message will be relayed from the received socket (`185.0.0.34`) to the interconnect. When this branch results in a … [View More]timeout, the proxy will try to do DNS SRV failover. This new branch and any subsequent branches will no longer use the initial received socket as source. In our case we see that the private address (`10.0.0.14`) is now being used as source address. ### Troubleshooting #### Reproduction DNS SRV: ``` _sip._udp.transit.net. SRV 10 10 5060 transit1.net. _sip._udp.transit.net. SRV 20 10 5060 transit2.net. transit1.net. A 185.10.20.30 transit2.net. A 185.10.20.31 ``` Kamailio: ``` $du = "sip:transit.net;transport=udp"; xinfo("Relaying [$rm] request: [$ru] with Call-ID [$ci]"); t_set_fr(0, 1000); if (not t_relay()) { sl_reply_error(); } ``` Network flow: ``` 12:30:00 INVITE udp:10.0.0.18:5060 => udp:185.0.0.34:5060 (internal request to proxy) 12:30:00 INVITE udp:185.0.0.34:5060 => udp:185.10.20.30:5060 (relaying from proxy to interconnect) ^^^^^^^^^^ (request times out after 1 second, proxy will do a failover to the next endpoint) 12:30:01 INVITE udp:10.0.0.14:5060 => udp:185.10.20.31:5060 (relaying to next interconnect address) ^^^^^^^^^ ``` #### Log Messages Attempt to see where it goes wrong: ``` onsend_route { xinfo("[$RAut] [$Rut] [$sas]\n"); xinfo("$snd(buf)\n"); } ``` ``` INFO: [sip:185.0.0.34:5060;transport=udp] [sip:185.0.0.34:5060;transport=udp] [udp:10.0.0.18:5060] INFO: INVITE sip:+1234567890@transit.net;user=phone SIP/2.0#015#012Record-Route: <sip:185.0.0.34;lr;ftag=tDr7m6erX1N3D>#015#012Via: SIP/2.0/UDP 10.0.0.14;branch=z9hG4bKafe7.7fb590e263fa44677514193a6a1156ce.1#015#012Via: SIP/2.0/UDP 10.0.0.18;received=10.0.0.18;rport=5060;branch=z9hG4bK6t59a17N60FcB ... ``` So the `Record-Route` seems to be correct, but the top most `Via` header shows the private IP address. The message is being sent from the private IP address as well and never reaches the second address from the interconnect. ### Possible Solutions A workaround to add `$fs = "udp:185.0.0.34:5060"` in the `onsend_route` seems to be effective. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.2.3 (x86_64/linux) 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: unknown compiled with gcc 7.4.0 ``` * **Operating System**: ``` Ubuntu 18.04 LTS Linux proxy4 4.15.0-64-generic #73-Ubuntu SMP Thu Sep 12 13:16:13 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux ``` -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] [kamailio 5.2.5] Wrong send socket on a multi homed proxy (#2181)
by vitalikvoip 02 Mar '20

02 Mar '20

### Description Kamailio fails to forward in-dialog request over TCP/TLS/WS/WSS connection. ### Troubleshooting kamailio 5.2 branch has a commit 09ac3e47ef79dbd599b7dec5b84ae3b792f025ed cherry picked from master branch. It makes sense for master because get_send_socket2() behavior has changed and function became smarter and also there were some patches to propagate connection it to the uac structure. After applying this patch to 5.2.x kamailio searches for an outgoing socket, receives the … [View More]

[kamailio/kamailio] Adding CDR as JSON functionality (#2107)
by Lucian Balaceanu 26 Feb '20

26 Feb '20

#### Pre-Submission Checklist    - [ ] Commit message has the format required by CONTRIBUTING guide - [ ] Commits are split per component (core, individual modules, libs, utils, ...) - [ ] Each component has a single commit (if not, squash them into one commit) - [ ] No commits to README files for modules (changes must be done to docbook files in `doc/` subfolder, the README file is autogenerated) #### Type Of Change - [ ] Small bug fix (non-breaking change which fixes an issue) - [ ] New feature (non-breaking change which adds new functionality) - [ ] Breaking change (fix or feature that would change existing functionality) #### Checklist:  - [ ] PR should be backported to stable branches - [ ] Tested changes locally - [ ] Related to issue #XXXX (replace XXXX with an open issue number) #### Description  These commits create a CDR addressed engine, similar to the one that acc module exports for acc message accounting. Such an engine made an extension module like acc_json possible. This CDR engine is then used in acc_json to write the functionality for logging CDRs in JSON format. I have added functions to the API exported by acc module instead of creating another separate CDR API, as I thought this is cleaner. I only implemented the acc_json logging to syslog (no message queue support yet).

[kamailio/kamailio] Kemi: sdp_with_transport() missing and sdp_transport() doesn't always help (#2194)
by Sebastian Damm 12 Feb '20

12 Feb '20

### Description In plain Kamailio language, we used the following line: ``` if ( sdp_with_transport("RTP/SAVP") ) { ``` Now we wanted to convert that to Kemi. Turns out, the `sdp_with_transport()` function is not exported to Kemi. So we thought, we could use `sdp_transport()` to work around the missing function. This works as long as there is only one transport in SDP. But if a phone sends two media streams in SDP, one with RTP/AVP and one with RTP/SAVP, `sdp_transport()` will return `-2`. … [View More]
