[kamailio/kamailio] Segfault when calling $sel(cfg_get...) (#1159)
by Sebastian Damm 20 Dec '18

20 Dec '18

### Description I set some configuration parameters in the global section of kamailio.cfg and wanted to read them later in request_route and reply_route. But when accessing them, Kamailio segfaults. However, I can read them via kamcmd after startup. ### Troubleshooting #### Reproduction Set the following config parameter in your kamailio.cfg in the global section: ``` config.foo = "hello Daniel" ``` later, put your request and reply route in the configuration file: ``` request_route { xlog("L_INFO", "Reading config.foo into variable"); $var(configfoo) = $sel(cfg_get.config.foo); } onreply_route { xlog("L_INFO", "Reading config.foo into variable"); $var(configfoo) = $sel(cfg_get.config.foo); } ``` #### Debugging Data gdb output is the following: ``` GNU gdb (Debian 7.7.1+dfsg-5) 7.7.1 Copyright (C) 2014 Free Software Foundation, Inc.

[kamailio/kamailio] Makefile.defs: default locks review (#1035)
by Daniel-Constantin Mierla 27 Sep '18

27 Sep '18

Apparently the default locks are set to PTHREAD mutex, when the architecture is not handled explicitely. It should be reviewed and eventually switch to standard POSIX, they should work everywhere while PTHREAD are targeting threads and work only in few cases for processes. -- You are receiving this because you are subscribed to this thread.

[kamailio] feature request: sample config for federation / peering with repro (#531)
by Daniel Pocock 27 Sep '18

27 Sep '18

repro servers peer with each other in a federated manner just like SMTP servers for email, but using TLS mutual authentication to prevent impersonation. Kamailio has TLS support and should be able to talk to such servers and other Kamailio servers in the same way. It would be good to create a recommended sample configuration for this type of service and also add it to the RTC Quick Start Guide: http://rtcquickstart.org/guide/multi/sip-proxy.html --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/531

[kamailio/kamailio] ERROR searching pvar "uac_req" in sample kamailio.cfg config file for PCSCF (#1123)

### Description I have configured a kamailio as PCSCF taking the configuration sample files (kamailio.cfg and pcscf.cfg) in https://github.com/kamailio/kamailio/tree/master/misc/examples/pcscf The version of kamailio installed is the 5.1. When I perform "service pcscf start" the services doesn't restart giving a parsing error for a pseudo variable called $uac_req. The error is found in this section: route[NATPING] { route(preload_pcscf); sht_iterator_start("nat_iterator", "natping"); while(sht_iterator_next("nat_iterator")) { xlog("OPTIONS to $shtitval(nat_iterator) via $shtitkey(nat_iterator)...\n"); $uac_req(method) = "OPTIONS"; $uac_req(ruri) = $shtitval(nat_iterator); $uac_req(furi) = PCSCF_URL; $uac_req(turi) = $shtitval(nat_iterator); $uac_req(ouri) = $shtitkey(nat_iterator); $uac_req(evroute) = 1; uac_req_send(); } sht_iterator_end("nat_iterator"); } I have checked that I have only one "uac.so" file in /usr/lib64/kamailio/modules/ and the date of the file is April 15th. So I guess that the file is updated. ### Troubleshooting #### Reproduction  #### Debugging Data ``` (paste your debugging data here) ``` #### Log Messages ERROR: <core> [core/pvapi.c:828]: pv_parse_spec2(): error searching pvar "uac_req" 0(2271) ERROR: <core> [core/pvapi.c:1032]: pv_parse_spec2(): wrong char [m/109] in [$uac_req(method)] at [9 (5)] 0(2271) CRITICAL: <core> [core/cfg.y:3414]: yyerror_at(): parse error in config file /etc/kamailio/pcscf/kamailio.cfg, line 906, column 3-18: Can't get from cache: $uac_req(method) ERROR: bad config file (1 errors) #### SIP Traffic  ``` (paste your sip traffic here) ``` ### Possible Solutions  ### Additional Information * **Kamailio Version** - output of `kamailio -v` version: kamailio 5.1.0-dev2 (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. id: unknown compiled with gcc 4.7.2 * **Operating System**:  Debian 8 -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] auth_db Deprecate email_address in database schemas (#858)
by Olle E. Johansson 03 Sep '18

03 Sep '18

I suggest we delete the "email_address" field in database schemas for auth_db. I think it was put there as an example of extendability but a lot of users seems confused about this and Kamailio by default does not use that field at all. Any opinions? If we reach an agreement we'll produce patches and clean up the various schemas. -- You are receiving this because you are subscribed to this thread.
