[kamailio/kamailio] PKG Memory Leak with RTPEngine Module with WebSocket (Issue #3777)

by vijaykumar-exotel

### Description  ### Troubleshooting - as checked further we particulartly tcp reciever process was consuming pkg memory , then further we checked from corex pkg_sumary for that process id, and found that rtpengine: rtpengine.c: send_rtpp_command was consuming highest memory. #### Reproduction console rtpengine url with ws endpoint.  this is reproducible, we can configure websocket in rtpengine module and then we can initate calls. and increase the number of calls over the period of time #### Debugging Data <img width="1399" alt="Screenshot 2024-03-06 at 4 30 16 PM" src="https://github.com/kamailio/kamailio/assets/115363081/0904892e-6a6e-4dc1-85…"> kamcmd pkg.stats entry: 24 pid: 378355 rank: 17 used: 7467640 free: 24348320 real_used: 9206112 total_size: 33554432 total_frags: 66 desc: tcp receiver (generic) child=0 kamcmd corex.pkg_summary pid 378355 Mar 6 16:31:52 coreproxy-4 /usr/local/sbin/kamailio[378355]: ALERT: qm_sums: qm_sums(): count= 8075 size= 4638760 bytes from rtpengine: rtpengine.c: send_rtpp_command(3040) ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` (paste your output here) version: kamailio 5.7.0 (x86_64/linux) flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, MEM_JOIN_FREE, 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_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED 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 on 01:04:28 Jan 25 2024 with gcc 9.4.0 ``` * **Operating System**:  ``` No LSB modules are available.

[kamailio/kamailio] Segfault in pua_dialoginfo.c when starting up with a dialog in the database (Issue #3743)

by Gianluca Nitti

### Description Kamailio segfaults on startup. After a bit of digging, it looks like the issue is caused by trying to publish something related to an expired dalog which is present in the database: ``` kamailio=# select * from dialog; id |

[kamailio/kamailio] [FEATURE] mid-call self-redirect call to new nexthop (Issue #3773)

by Jakihiko

These below is sample diagram, where kamailio/rtpengine act as an SBC <img width="1604" alt="image" src="https://github.com/kamailio/kamailio/assets/143789335/b9540fb3-c1bf-4a78-b1…"> * There is an active call carrier, kamailio/rtpngine and Asterisk1 * Asterisk1 went down (power shortage, or network ..) * What I want is kamailio self-redirect the call to Asterisk2 **Describe the solution you'd like** Ideally, kamailio provide the command line to tell which call will be self-redirect to the new destination, eg: `kamcmd -x sefl_redirect_callid <call-id> <destionation-ip>` Noted: I read the https://blog.opensips.org/2021/06/09/media-re-anchoring-using-opensips-3-2/ but re-INVITE to carrier seem not appropriate in my case due to call rate limit. I'm looking for a new solution where I don't need to use re-INVITE when Asterisk down. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3773 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] support zero media stream for sdp parsing module (Issue #3779)

by Dakna adnane

when using sdp module to parse sdp I noticed that function called from sdp_get return -1 when no m-lines are present in sdp , normally we should accept sdp without m -line because it can be at a later time through a modified offer , how can we accept such sdp without changing source code for function "parse_sdp_session" -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3779 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] registrar: adding contact and UA to xavp_cfg (Issue #3753)

by nirvanr-nextiva

### Description We are using Kamailio as a 'mid-registrar', and saving the location record (i.e calling registrar.save()) in the reply-route depending on received status code from other registrar. We noticed the saved location record had the contact URI (incl. instance id) and UA from response message; instead we would like to use the contact and UA from the original request. This feature change is similar to what was added for `tcpconn_id` in PR: https://github.com/kamailio/kamailio/pull/3430. i.e. we would set the request's contact URI and UA in `xavp_cfg` variable. Then `registrar.save.c` would use the contact and UA from `xavp_cfg`. Thanks. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3753 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Chaining Transformations {uri.param,received}{uri.host} does not work for IPv6 (Issue #3794)

by ChristianBergerSipgate

### Description Chaining the transformations {uri.param,received} and {uri.host} does not work if the address is IPv6. It works for IPv4 addresses. #### Reproduction We tested this with the following code: ``` if ($du != $null) { $var(received_uri)=$(du{uri.param,received}); if ($var(received_uri)!="") { $var(subscriber_host)=$(var(received_uri){uri.host}); } $var(test_tmp)=$(du{uri.param,received}{uri.host}); xlog("L_ERR", "WURST subscriber_host=$var(subscriber_host) test_tmp=$var(test_tmp) du=$du received_uri=$var(received_uri)"); } } #### Log Messages For IPv6 this gives us: ``` "module": "pv", "file": "pv_trans.c", "line": 1545, "function": "tr_eval_uri", "logprefix": ", "callid": "1-91(a)1.2.4.16", "x-telco-capture-id": "<null>"", "message": **"invalid uri [ab:cdef:dead:beef]:1234]\n"** "module": "core", "file": "core/lvalue.c", "line": 351, "function": "lval_pvar_assign", "logprefix": ", "callid": "1-91(a)1.2.4.16", "x-telco-capture-id": "<null>"", "message": "non existing right pvar\n" "module": "core", "file": "core/lvalue.c", "line": 411, "function": "lval_assign", "logprefix": ", "callid": "1-91(a)1.2.4.16", "x-telco-capture-id": "<null>"", "message": "assignment failed at pos: (1432,19-1432,53)\n" "module": "xlog", "file": "xlog.c", "line": 278, "function": "", "logprefix": ", "callid": "1-91(a)1.2.4.16", "x-telco-capture-id": "<null>"", "message": "WURST subscriber_host=[2001:db8:0123:4567:89ab:cdef:dead:beef] test_tmp=0 du=sip:1.2.4.129;lr;received=sip[2001:db8:0123:4567:89ab:cdef:dead:beef]:1234 received_uri=sip:[2001:db8:0123:4567:89ab:cdef:dead:beef]:1234" "module": "xlog", "file": "xlog.c", "line": 278, "function": "", "logprefix": ", "callid": "1-91(a)1.2.4.16", "x-telco-capture-id": "<null>"", "message": "determineSubscribeIpFamily: contacts worked path=0 ip=[2001:db8:0123:4567:89ab:cdef:dead:beef] af=6" ``` For IPv4 it works: `{ "idx": 8, "pid": 577, "level": "ERROR", "module": "xlog", "file": "xlog.c", "line": 278, "function": "", "logprefix": ", "callid": "1-91(a)1.2.4.16", "x-telco-capture-id": "<null>"", "message": "WURST subscriber_host=12.34.56.78 test_tmp=12.34.56.78 du=sip:1.2.4.149;lr;received=sip:12.34.56.78:1234 received_uri=sip:12.34.56.78:1234" } ` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3794 You are receiving this because you are subscribed to this thread.
