[kamailio/kamailio] Retransmission for uac_auth generated INVITEs do not include CSeq mangling (track_cseq_updates) (#679)

by Carlos Cruz Luengo

I am having issues using uac_auth function and dialog module track_cseq_update option. The issue is related to CSeq mangling done by dialog module to keep synced CSeq in both parties involved. It works fine when 1xx response is received for generated INVITE before retr_timer1 expires but, if not, the generated retransmission has the same CSeq as the original INVITE (the one without Authorization headers), instead of increasing CSeq by one again: - INVITE sent by UAC (CSeq 100). - 407 from UAS. - INVITE generated by uac_auth (CSeq 101). - (... no answer ...) - Retransmission INVITE with Authorization header but with CSeq 100. This is the minimal configuration file needed to test this behaviour: ``` loadmodule "tm.so" loadmodule "pv.so" loadmodule "sl.so" loadmodule "avpops.so" loadmodule "dialog.so" loadmodule "uac.so" loadmodule "rr.so" modparam("dialog", "dlg_flag", 1) modparam("dialog", "track_cseq_updates", 1) modparam("uac", "auth_realm_avp", "$avp(realm)") modparam("uac", "auth_username_avp", "$avp(provideruser)") modparam("uac", "auth_password_avp", "$avp(secret)") modparam("tm", "retr_timer1", 100) request_route { dlg_manage(); $ru = "sip:test@**SIPSERVER**"; t_on_failure("MANAGE_FAILURE"); t_relay(); exit; } failure_route[MANAGE_FAILURE] { if (t_is_canceled()) { exit; } if (t_check_status("(401)|(407)")) { $avp(realm) = ''; $avp(provideruser) = 'foo'; $avp(secret) = 'bar'; uac_auth(); } t_on_failure("MANAGE_FAILURE"); t_relay(); exit;} ``` This is the Kamailio version I am using on a amd64 machine (Debian 7): ``` version: kamailio 4.4.1 (x86_64/linux) 99e1c3 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_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: 99e1c3 compiled on 13:37:42 Jun 20 2016 with gcc 4.7.2 ``` Is something wrong on my kamailio.cfg?

[kamailio/kamailio] Conflict between tls module and mongo-c-driver with ssl enabled (#660)

by Daniel-Constantin Mierla

Crashes has been reported when using mongodb modules compiled with mongo-c-driver having ssl enabled. Using mongo-c-driver without ssl enabled doesn't expose the issue. To investigate mongo-c-driver sources and see if it is messing up with the memory manager set for libssl. --- You are receiving this because you are subscribed to this thread.

[kamailio] Module:sca Line seize does not release after some 'bye's (#341)

by Kevin Scott Adams

I have a situation that I can't get my head around. Every so often I have a SCA seized and I need to manually release it. Here is the log of the sca and bye from the event logs. messages-20150920:Sep 18 14:35:28 sip-registrar /usr/sbin/kamailio[7608]: ERROR: sca [sca_call_info.c:1580]: sca_call_info_bye_handler(): sca_call_info_bye_handler: sip:Mindfield@kamailio.newgarllc.com dialog leg 96b9ad37-9a7fa462-15c35d3(a)192.168.1.117;1c389191866 is not active messages-20150920:Sep 18 14:35:28 sip-registrar /usr/sbin/kamailio[7610]: NOTICE: acc [acc.c:317]: acc_log_request(): ACC: transaction answered: timestamp=1442601328;method=BYE;from_tag=76C3EC1F-114D759A;to_tag=1c389191866;call_id=96b9ad37-9a7fa462-15c35d3(a)192.168.1.117;code=200;reason=OK;src_user=Mindfield;src_domain=kamailio.newgarllc.com;src_ip=192.168.1.40;dst_ouser=Mindfield;dst_user=Mindfield;dst_domain=192.168.1.117 And the kamcmd showing the seize line (in this case both are seized) sip:Mindfield@kamailio.newgarllc.com 1 active 1442601278 sip:Mindfield@192.168.1.117 sip:1030@192.168.1.40:5060 96b9ad37-9a7fa462-15c35d3(a)192.168.1.117 76C3EC1F-114D759A 1c389191866 I am running Kamailio 4.2.6. The phones are Polycom VVX 310/410 running 5.3.1. And the PSTN gateway is an Audiocodes Mediant 1000 running 6.60A.292.001. The call volume is light so I don't think there is a lot of traffic but there is about 16 phones one SCA. It is not happening all time. Could be a couple days that nothing happens and then there could be a couple days that it happens multiple times a day. I can't find a common element that would be causing this unless the 'bye' is closing the call before the SCA has a chance to do something with it.

CONID and tcp:close event on outbound TCP connections

by Olle E. Johansson

Hi! Trying to debug a case where I don’t get an event_route execution for a TCP connection. IN my case, Kamailio opens a new TCP connection to another server in order to send an in-dialog request. When that connection closes, there’s no event route being executed. The tcpops module use default config, which means that the event route tcp:closed is globally enabled. I’ve been digging in the tcp code but can’t really figure it out… ;-) Cheers, /O

[kamailio/kamailio] Fix check_route_param() (#663)

by Dragos Oancea

Given that there are multiple Route sets , each with one param , check_route_param() function fails to search the proper param.s string . The condition params.s[0]!=';' holds false and it stops the loop only when it encounters another ";" character which is not part of the Route header . Eg: (these are not actual Route params, but this is what it is printing instead - this is part of my INVITE, and these headers are above Route ): rr [loose.c:985]: check_route_param(): params are <;spi-s=424238335#015#012Require: sec-agree#015#012Proxy-Require: sec-agree#015#012Cont> This patch is a functional workaround. Note I have also seen there routed_params.s not pointing to the actual params , so perhaps there might be another issue before reaching this code.

[kamailio/kamailio] TM Bus error on SPARC (#655)

by sjthomason

Calls to cfg_get(tm, tm_cfg, default_reason) and cfg_get(tm, tm_cfg, tm_auto_inv_100_r) on Solaris/SPARC cause a bus error. Looking though some mailing list archives, it appears a similar issue was fixed in the registrar module but I couldn't find patch referenced. --- You are receiving this because you are subscribed to this thread.
