[kamailio] Anyone thinking about adding JWT (JSON Web Token) support to Kamailio (#29)
by mading087 24 Jul '20

24 Jul '20

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

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. If Contact header exists in "180 Ringing" - all works as expected. ### Troubleshooting #### Reproduction Load and configure topos module Make call with "180 Ringing" without Contact header - kamailio will not forward it. #### Log Messages ``` ERROR: topos [tps_storage.c:340]: tps_storage_link_msg(): bad sip message or missing Contact hdr ``` #### SIP Traffic ``` SIP/2.0 180 Ringing Via: SIP/2.0/TLS 1.2.3.4:5061;branch=z9hG4bKef45.8c75f0bae8a59dfaec6ff533ff0f3b2d.0 From: <sip:1111@1.2.3.4:5061>;tag=02000879948559 To: <sip:2.2.2.2@5.6.7.8:5061;transport=tls;user=phone>;tag=SDbsq8499-y2pMOVV Call-ID: apdW7374315131g0bcGhEfDjFof CSeq: 988207425 INVITE User-Agent: agent Supported: replaces, outbound Content-Length: 0 ``` ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.1.6 (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 ``` * **Operating System**: ``` Red Hat Enterprise Linux Server 7.3 3.10.0-514.el7.x86_64 #1 SMP Wed Oct 19 11:24:13 EDT 2016 x86_64 x86_64 x86_64 GNU/Linux ``` -- You are receiving this because you are subscribed to this thread.

[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.

[kamailio/kamailio] error: 'pkg/docker' does not have a commit checked out (#2003)
by Daniel-Constantin Mierla 20 May '20

20 May '20

When I just tried to do a commit today, I got the following error: ``` kamailio $ git ci . error: 'pkg/docker' does not have a commit checked out fatal: updating files failed ``` It is related to the `pkg/docker` submodule referencing to kamailio/kamailio-ci. Not sure if this is due to a new git version or something else, because I did commits in that folder a few days ago. To get is sorted out, I did: ``` kamailio $ git submodule update pkg/docker Submodule path 'pkg/docker' not initialized Maybe you want to use 'update --init'? kamailio $ git submodule update --init pkg/docker Submodule 'pkg/docker' (https://github.com/kamailio/kamailio-ci.git) registered for path 'pkg/docker' Cloning into '/.../kamailio/pkg/docker'... Submodule path 'pkg/docker': checked out 'b92a1c899b8c474afadd0cf29dd7cb4ea01a3466' ``` Then it worked to do the commit. I wonder if this is going to break the process we were used with, specially the installation guidelines from GIT repo. Therefore I open this item to see if we really need the to have `pkg/docker` submodule, or better have the docker files directly in the repo. Other options to keep things sane and simple?

[kamailio/kamailio] TLS module compiled with outdated OpenSSL version for Ubuntu bionic (#2018)
by welljsjs 14 Apr '20

14 Apr '20

### Description  Ubuntu Bionic 18.04.02 LTS ships with "OpenSSL 1.1.1 11 Sep 2018" (0x1010100f), whereas the `kamailio-tls-modules` package is compiled with "OpenSSL 1.1.0g 2 Nov 2017" (0x1010007f). I installed Kamailio from the Kamailio repositories (not from the Ubuntu repositories). This leads to Kamailio being unable to start as it complains about the OpenSSL versions being too different from each other. Overriding the OpenSSl version check by enabling `tls_force_run` does not solve the issue, instead, it leads to Kamailio emitting multiple errors.  #### Reproduction I installed Kamailio from the official Kamailio apt sources (nightly build, the same occurs for the latest stable version 5.2). ``` deb http://deb.kamailio.org/kamailiodev-nightly bionic main deb-src http://deb.kamailio.org/kamailiodev-nightly bionic main ``` I enabled TLS and edited the configuration files accordingly.    ``` (paste your debugging data here) ``` #### Log Messages ``` CRITICAL: tls [tls_init.c:677]: init_tls_h(): installed openssl library version is too different from the library the kamailio tls module was compiled with: installed "OpenSSL 1.1.1 11 Sep 2018" (0x1010100f), compiled "OpenSSL 1.1.0g 2 Nov 2017" (0x1010007f).#012 Please make sure a compatible version is used (tls_force_run in kamailio.cfg will override this check) ```  ### Possible Solutions Recompile and publish the `kamailio-tls-modules` package compiled with OpenSSL 1.1.1b. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.3.0-dev6 (x86_64/linux) flags: STATS: Off, 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: unknown compiled with gcc 7.3.0 ``` * **Operating System**:  ``` Linux hostname 4.15.0-55-generic #60-Ubuntu SMP Tue Jul 2 18:22:20 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux Description: Ubuntu 18.04.2 LTS Release: 18.04 ``` -- You are receiving this because you are subscribed to this thread.

some missing kemi module functions
by David Escartin 05 Feb '20

05 Feb '20

hello all we are trying to rewrite our code to lua kemi, and we have found some issues/questions until we would like to share with you. -module call_obj not exported, we have tested a patch for the module to export the functions to kemi, which seems works fine -KSR.xlog.xinfo seems not able to select a facility as we currently can like xlog("LOG_LOCAL7", "L_NOTICE", "$var(xxxx)"); -module sipt not exported yet, must use ksr.x.modf ? will be exported for a future version? -on 5.3.0-dev5 we don't see the KSR.dialog.var_sets() and KSR.dialog.var_get/e/w() functions in the code, so we do use KSR.pv functions to set and retrieve those dialog vars. However i see them on master branch. Which kamailio release would have them? -sdpops function sdp_with_codecs_by_name seems to not me exported, is it on a todo list? -textops module, missing remove_hf and append_hf functions exported. We already did a patch for the remove_hf, despite we could work with textopsx remove_hf_value function to get the almost the same functionality. However, with append_hf i'm having some more issues. We cannot use modf to exec those funtions, we get something like For ---> KSR.x.modf("append_hf", "User-Agent: test", "To"); I get something like ----> Jun 27 07:19:16 proxy-1 /usr/local/kamailio/sbin/kamailio[5525]: ERROR: app_lua [app_lua_sr.c:188]: lua_sr_modf(): function 'append_hf' has fixup - cannot be used I could append a new header and not only at the end of the message by replacing a header called the same way, by doing something like KSR.textopsx.insert_hf_value("header", "value"); KSR.textopsx.remove_hf_value("header[-1]"); but i'm not able to insert a header after another different one like we can do with append_hf("header:value", "To") for instance. Is it expected to have it on a next commit those append_hf and remove_hf exported. Would we do a pull request with the ki_remove_hf we already have and the call_obj functions too? We can check to export append_hf too if it's not planned to be done thanks a lot and regards david
