[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] mod kazoo: wrong kazoo_publish example (#2627)
by sergey-safarov 21 Sep '21

21 Sep '21

### Description Example 1.21. kazoo_publish usage contains string ``` $var(amqp_payload_request) = "{'Event-Category' : 'directory', 'Event-Name' : 'reg_success', 'Contact' : '" + $var(fs_contact) + "', 'Call-ID' : '" + $ci + "', 'Realm' : '" + $fd +"', 'Username' : '" + $fU + "', 'From-User' : '" + $fU + "', 'From-Host' : '" + $fd + "', 'To-User' : '" + $tU +"', 'To-Host' : '" + $td + "', 'User-Agent' : '" + $ua +"' ," + $var(register_contants)+ " }"; ``` This example did not work because the string generates broken JSON: 1. here present value ` $var(register_contants)` but key is not present 2. JSON key and value must be started and terminated by `"` symbol (not by `'`) -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Random segfault or general protection crash on siptrace.so module (#2718)
by Joshua Riffle 15 Sep '21

15 Sep '21

### Description After upgrading from Kamailio 5.2.x, a high volume Kamailio 5.4.4 instance randomly crashes with either a general protection or segfault error message in `siptrace.so` during use of `sip_trace` function from one of its child processes (which cascades to the parent crashing). This appears to occur once about every 36 hours on average, but has not yet appeared to correspond with any particular event. We are continuing to collect debug information and will be populating this ticket as more information becomes available. However, this issue has been observed. Sip trace function is applied in this example snippet: ``` # ------- siptrace -------- modparam("siptrace", "hep_mode_on", 1) modparam("siptrace", "hep_version", 3) modparam("siptrace", "trace_to_database", 0) modparam("siptrace", "trace_flag", 22) modparam("siptrace", "trace_on", 1) request_route { #.... if ( is_method("INVITE") && !has_totag() ) { # Only start sip_trace on initial INVITE sip_trace("HEP_URL","$ci-MY_IP","d"); } setflag(22); #... } ``` ### Troubleshooting We attempted packet collection with Homer v5 and Homer v7 and changed between HEP protocol v2 and v3. #### Reproduction We have not determined a means of reproducing this issue without simply letting the server run until a crash occurs. There are four almost identical servers all experiencing the same random crashing but not at the same time. #### Debugging Data Our next troubleshooting case will be to simply comment out the `sip_trace` function, but this effectively disables the `siptrace` module completely rather than addressing an underlying problem. Core dumps are still in-progress for retrieval. Debug logs should also be more readily available soon. There will be delays since these are high volume production servers.  #### Log Messages All of them have randomly crashed with the following example log entry. Regardless of troubleshooting tactics to date: ``` kernel: traps: kamailio[7579] general protection ip:7fb1a64e2dbf sp:7ffc60f04180 error:0 in siptrace.so[7fb1a64b8000+4e000] systemd: kamailio.service: main process exited, code=exited, status=1/FAILURE systemd: Unit kamailio.service entered failed state. systemd: kamailio.service failed. ``` #### SIP Traffic To date, there is no corresponding SIP Traffic with the crash. ### Possible Solutions To date, only disabling the `siptrace` module seems to be the solution. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.4.4 (x86_64/linux) e16352 flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, 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: e16352 compiled on 15:56:46 Feb 15 2021 with gcc 4.8.5 ``` * **Operating System**:  ``` Linux <hostname> 3.10.0-957.27.2.el7.x86_64 #1 SMP Mon Jul 29 17:46:05 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux ``` -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] db_redis: add support for native redis cluster (#1997)
by George Diamantopoulos 15 Sep '21

15 Sep '21

The db_redis module seems to only support connecting with a single redis instance. It is not evident from the documentation if it implements support for native redis cluster by honouring 'MOVED' replies. ndb_redis seems to have support for native redis clusters, and supports both automatic (see allow_dynamic_nodes parameter of ndb_redis) and manual configuration of redis nodes. Since both modules are based on the hiredis library, is it safe to assume this support could be easily implemented, with some code sharing between the two modules perhaps? If db_redis supports clusters with automatic configuration only (by processing MOVED replies), perhaps the module's documentation should be updated to reflect that. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] JSON CEE structured logging (#2797)
by Daniel Pocock 15 Sep '21

15 Sep '21

### Description Kamailio recently added JSON logging support, described on these two pages: https://www.kamailio.org/w/2020/04/structured-json-logging/ https://www.kamailio.org/wiki/cookbooks/devel/core#log_engine_cli_parameter Structured logging is particularly useful when: 1. there are multiple applications involved in a call (e.g. Kamailio, Kurento, coTurn, Apache) 2. all the applications create JSON logs using identical field names I recently made contributions to reSIProcate, GStreamer and Kurento to support the JSON CEE field names. It would be very easy to replicate in Kamailio. https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/847 https://github.com/Kurento/kurento-media-server/pull/17 https://github.com/resiprocate/resiprocate/commit/d1df9aeb956be79253560fe36… Notice that ```rsyslog``` can receive legacy Syslog events from VoIP hardware, Cisco and Polycom phones and it can convert them to JSON CEE and push them into the document store where they will meet the records from Kamailio. This is another case where it is really useful if all the JSON from different applications is using CEE. Here are the JSON CEE field names: https://cee.mitre.org/language/1.0-beta1/core-profile.html ### Expected behavior Extend the config setting so that people can request CEE on the command line. #### Actual observed behavior #### Debugging Data ``` (paste your debugging data here) ``` #### Log Messages  ``` (paste your log messages here) ``` #### SIP Traffic  ``` (paste your sip traffic here) ``` ### Possible Solutions  ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` (paste your output here) ``` * **Operating System**:  ``` (paste your output here) ``` -- You are receiving this because you are subscribed to this thread.

We were getting an error which is mentioned above. We double-checked TLS and TCP connections and they were normal. We have 5000+ TLS connections and the max connection limit is 30,000. So we were not exceeding the TLS connection limit. We also verified open_files_limits.
