Releasing Kamailio v5.3.4
by Daniel-Constantin Mierla 06 May '20

06 May '20

Hello, based on the discussions from yesterday's online devel meeting, I am planning to release next week (likely on Wednesday, May 6) the next minor version out of branch 5.3, respectively 5.3.4. Should anyone be aware of issues not reported to the bug tracker or commits for fixes in master not backported to 5.3 branch, let us know. For new issues, the best is to report them on the tracker. For commits, you can provide links/hashids or make pull requests. Cheers, Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda

[kamailio/kamailio] Continued OpenSSL 1.1 crashes with 5.3.0 (#2121)
by Nathan Whitehorn 05 May '20

05 May '20

### Description After upgrading to 5.3.0 from 5.2.2 (standard packages on FreeBSD 12.0), I am experiencing intermittent crashes related to handling of BYE messages. ### Troubleshooting #### Reproduction This happens ~ weekly and I have not found a good way to reproduce it. #### Debugging Data An example backtrace is below from the last dumped core (the SIGSEGV one); unfortunately it overwrote the earlier one: ``` * thread #1, name = 'kamailio', stop reason = signal SIGSEGV * frame #0: 0x00000008009c5b79 libc.so.7`___lldb_unnamed_symbol403$$libc.so.7 + 41 frame #1: 0x00000008009ed63e libc.so.7`__free + 990 frame #2: 0x000000080271562b libthr.so.3`pthread_rwlock_destroy + 59 frame #3: 0x0000000802bedbf6 libcrypto.so.111`CRYPTO_THREAD_lock_free + 22 frame #4: 0x0000000802aef3c4 libcrypto.so.111`RSA_free + 100 frame #5: 0x0000000802b10c32 libcrypto.so.111`EVP_PKEY_free + 66 frame #6: 0x000000080296ed86 libssl.so.111`___lldb_unnamed_symbol646$$libssl.so.111 + 134 frame #7: 0x000000080295f93c libssl.so.111`SSL_CTX_free + 236 frame #8: 0x00000008028aee42 tls.so`tls_free_domain + 114 frame #9: 0x00000008028af1d7 tls.so`tls_free_cfg + 199 frame #10: 0x00000008028af2df tls.so`tls_destroy_cfg + 191 frame #11: 0x00000008028ad1f1 tls.so`destroy_tls_h + 1185 frame #12: 0x000000000041adea kamailio`destroy_tls + 26 frame #13: 0x00000000002e36fd kamailio`cleanup + 269 frame #14: 0x00000000002eb5b7 kamailio`___lldb_unnamed_symbol5$$kamailio + 1351 frame #15: 0x00000000002ea5e5 kamailio`handle_sigs + 21669 frame #16: 0x00000000002fb83e kamailio`main_loop + 40014 frame #17: 0x0000000000307d2b kamailio`main + 50267 frame #18: 0x00000000002e311b kamailio`_start + 283 ``` This is with OpenSSL 1.1 With the LD_PRELOAD hack to 5.2.2, things were completely stable; I am trying to use kamailio without the LD_PRELOAD'ed mutex wrapper now, which I believe is no longer required. It looks like the SSL-related stuff in the TLS crash (which was 5 minutes later!) is unrelated to the initial problem and may just be an artifact of one of the kamailio processes crashing earlier. #### Log Messages ``` Nov 2 08:11:31 home /usr/local/sbin/kamailio[94702]: CRITICAL: {1 527440 BYE 973470944-5061-16392(a)BA.A.B.I} <core> [core/mem/q_malloc.c:149]: qm_debug_check_frag(): BUG: qm: prev. fragm. tail overwritten(c0c0c000, abcdefed)[0x801544c58:0x801544c90]!

Roadmap to the next major release - Kamailio v5.4.0
by Daniel-Constantin Mierla 05 May '20

05 May '20

Hello, I am going to send a few emails on different topics to inform the broader community on mailing lists about what was discussed during the last online development meeting that happened last Wednesday, so everyone becomes aware and add own opinions and suggestions. First here is about the next major release, which is considered for the mid of summer. To allow the usual 1-1.5 months of testing time frame, the development has to be frozen in the first part of June (more or less one month from now on). If there will be no other proposals in the near future that end up in postponing the release target date, then try to push to master branch (or do pull requests) any new features that you want in Kamailio 5.4.x in the next 4-5 weeks. Once the code is frozen, you would have to wait for another release cycle to get new features in a stable branch. During the online meeting there was no major missing feature reported, if anyone here knows any, describe it and maybe some developer has time to implement it. Cheers, Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda

info: in-memory presentity records
by Daniel-Constantin Mierla 05 May '20

05 May '20

Hello, the presentity records (PUBLISH data) stored by the presence module needed always an external storage backend (sql/no-sql database), for subscriptions (active watchers) it was possible to use memory caching only. I recently added support for cache-only module for PUBLISH data as well, more details are presented in the news article: * https://www.kamailio.org/w/2020/05/in-memory-presentity-records/ That could help simplifying network architecture on distributed platforms leveraging cloud infrastructure and using replications mechanisms (e.g., dmq, evapi+pua_json, nsq, ...) between the Kamailio nodes. The impact on the code was quite significant, given that any PUBLISH triggers a series of internal tasks (apply xcap rules, update watchers, ...), therefore I am calling for community testing to be sure old operational modes were not affected as well as testing the new mode to discover eventual issues -- just open an item on bug tracker when a problem is discovered. Special credits to Fred Posner (lod.com) for supporting the development of this feature and to Emmanuel Schmidbauer for testing and troubleshooting in the early phase of development.
