#### 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 #1911 #### Description  The goal was to have a different, more complex hashing algorithm that would offer a better distribution among nodes. We've seen in production that the current algorithm does not perform well under heavy load therefore we decided to add SHA1 hashing. After running performance tests we've decided that we need a cryptographic function in order to have the best results mostly when the callids have small entropy. In order to add SHA1, a new API was added in crypto module exporting a function applying SHA1 to a string. The API was used in rtpengine module over the callid. After this operation the hash was calculated as before except for applying 0xFF mask over the hash as it was done before, which restrains the power of this algorithm.

[kamailio/kamailio] Active dialog stats stays static on a passive kamailio node that replicates dialogs via DMQ (#1692)
by Joel Serrano 11 Aug '20

11 Aug '20

### Description In a setup with 2 kamailios in active/passive with a virtual IP that failovers between them: sbc01 (active) is handling calls. sbc02 (passive) is started, and does an initial dialog sync via DMQ ``` root@sbc01:~# kamctl rpc stats.get_statistics all | grep dialog "dialog:active_dialogs = 39", "dialog:early_dialogs = 2", "dialog:expired_dialogs = 0", "dialog:failed_dialogs = 583", "dialog:processed_dialogs = 2527", root@sbc01:~# ``` ``` root@sbc02:/etc/kamailio# kamctl rpc stats.get_statistics all | grep dialog "dialog:active_dialogs = 39", "dialog:early_dialogs = 0", "dialog:expired_dialogs = 0", "dialog:failed_dialogs = 0", "dialog:processed_dialogs = 0", root@sbc02:/etc/kamailio# ``` >From that point onwards, as long as sbc01 stays as active, sbc02 stays as passive, and no restarts occur anywhere, the values for `dialog` metrics in sbc02 will not change and remain as they are, in the previous example, active_dialogs would remain as 39. ### Troubleshooting This was discovered during some tests from #1591 #### Reproduction Setup 2 kamailio instances that replicate dialogs via DMQ. 1- On Kamailio1 put some traffic to have some active dialogs (must call `dlg_manage()` in routing script for these test calls) 2- Start Kamailio2 3- Compare output of: `kamcmd stats.get_statistics dialog:` on both nodes. 4- Alter the amount of active dialogs on Kamailio1 (either end some or create new ones). 5- Repeat step 3. Kamailio1 --> Step5 will have different values from Step3. Kamailio2 --> Step5 will have exactly the same values from Step3. ### Possible Solutions `dialog:active_dialogs` should remain as 0 on Kamailio2, as technically there are no dialogs being handled by that server, it only has information of replicated dialogs and those stats are available in the `dlg.stats_active` metric. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` # kamailio -V version: kamailio 5.2.0-pre1 (x86_64/linux) 2ecf60-dirty 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: 2ecf60 -dirty compiled with gcc 6.3.0 ``` * **Operating System**:  ``` root@sbc02:~# lsb_release -a No LSB modules are available.

[kamailio] Anyone thinking about adding JWT (JSON Web Token) support to Kamailio (#29)

It seems a good idea to support JWT as a new SIP authorization method. Wonder if anyone is interested? Think auth_db would be the best spot to add support for JWT. --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/29

[kamailio/kamailio] 180 Ringing without Contact with TOPOS enabled (#1720)
by Sergey Basov 05 Jun '20

### Description Kamailio with TOPOS enabled acts as a proxy between SIP client and SBC. When client sends "180 Ringing" without Contact header - kamailio does not forward it to SBC.

[kamailio/kamailio] Configure permissions module without database (#2037)
by Sebastian Damm 25 May '20

25 May '20

### Description In our setup, we try to eliminate setup configuration in database and replace it with files. The advantage is, that we can maintain those files via puppet or ansible, and since we always rewrite the whole file, we don't have to take care about deleting obsolete entries. We can run different Kamailio versions without having problems with the version table when using the same database. And finally, we can stop all those local mysqld processes on a lot of machines. Modules like the dispatcher module were easy to change. But the permissions module is not prepared to run without database, if you want to use `allow_trusted()` or `allow_source_address()` and similar. The only option to feed those functions with data is a database table. ### Expected behavior We would like to place files for trusted and address into the Kamailio directory and have Kamailio read from those files during startup or after reload commands. #### Actual observed behavior Data for trusted and address have to reside inside a database. -- You are receiving this because you are subscribed to this thread.
