[kamailio/kamailio] Kamailio crash with in-memory publ_cache = 2 (Issue #3008)

by Joe Mordica

### Description Usage of `modparam("presence", "publ_cache", 2)` causes kamailio to crash shortly after starting up. This only happens when subscribe traffic is high (400 requests per second avg). ### Troubleshooting #### Reproduction The issue can be reproduced by starting up kamailio with the option above enabled and ~400 subscribe requests per second. The crash happens ~20 seconds after startup. #### Debugging Data  ``` (paste your debugging data here) ``` #### Log Messages  ``` kernel: kamailio[25401]: segfault at 0 ip 00007f4a0a22d4d7 sp 00007fff6064a370 error 4 in presence.so[7f4a0a21e000+fe000] ``` #### SIP Traffic  ``` (paste your sip traffic here) ``` ### Possible Solutions Running with the default ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` (paste your output here) ``` * **Operating System**:  ``` Linux hostName 2.6.32-754.11.1.el6.x86_64 #1 SMP Tue Feb 26 15:38:56 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux version: kamailio 5.4.3 (x86_64/linux) e19ae3 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: e19ae3 compiled on 18:24:43 Dec 14 2020 with gcc 4.4.7 ``` I realize this is an older version so if it's resolved in a newer one let me know. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3008 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] dialog keep-alive ignores listening ip/port (Issue #3018)

by Riccardo-78

### Description When dialog module needs to send keep-alive to caller and/or called it doens't check if the ip address and port of the dialog is the current listening ip/port. If you have two distinct kamailio instances sharing a single dialog database, both instances are sending the OPTIONS and not just the one which handled the call at setup time.  ### Troubleshooting #### Reproduction Start two instance with a shared dialog database and db_mode set to 1 (realtime), set property ka-src for every dialog in kamailio cfg. Setup a long call and restart the instance not involved in the call. You should see it starting to send OPTIONS. ### Possible Solutions In dlg_send_ka, if the ip/port stored in the dialog db is not present in the listening ip/port set, skip the check.  ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.5.2 (x86_64/linux) 55e232 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_BLOCKLIST, 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: 55e232 compiled on 14:20:31 Aug 25 2021 with gcc 4.8.5 ``` * **Operating System**: Centos 7  -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3018 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Setting rtpengine DTLS flags on specific user agents only? (Issue #3025)

by Ryan Gehrig

Hello, I need to enable DTLS (e.g. add "SDES-off DTLS" to my $var(rtpengine_flags), but only on specific endpoint device types. So far, on an inbound call, the SDP comes from Asterisk, and once it hits this specific endpoint, if no encryption is enabled, the endpoint rejects the call and I get "488 Not Acceptable Here". If I statically enable the DTLS options in kamailio, then the endpoint accepts it and the call connects. I need to do conditional logic in the kam config, so unless there is a way to reinvite a second time, adding DTLS, I am now trying to figure out a way to determine the destination user agent, potentially via the most recent sip registration or contact/location data saved, then based on the user agent that was registered, I can decide to enable or disable DTLS. Open to any and all ideas on the right way to do this! Thanks!

Advertised Address in LRKProxy

by Mojtaba

Hello there, In regard to developing LRKPRoxy to use behind NAT, I am planning to add some features to support Advertised Address. For example, this feature could be used when the LRKProxy is used in AWS. Does anybody have any opinion in this regard? or some extra features? -- --Mojtaba Esfandiari.S
