rare crash , race condition between 183 and 408 ?
by Dragos Oancea 05 Nov '14

05 Nov '14

Hi all & hi Daniel , We had a crash with version 4.0.5 today . I looks like it happens due to a race condition between a provisional response (183) and the generation of a 408 . We send the INVITE, get a `100 Trying` from upstream , then we get a `183 Session Progress` from upstream , then after exactly 1 minute , we get another `183 Session Progress` from upstream. At this moment kamailio crashed. Some tm params we have : modparam("tm", "fr_timer", 5000) modparam("tm", "fr_inv_timer", 60000) <- our final reply timer is 1 minute . modparam("tm", "restart_fr_on_each_reply", 1) GDB output and logs here: kamailio 4.0.5 crash - in fake_req() - race cond - Pastebin.com kamailio 4.0.5 crash - in fake_req() - race cond - Paste... (gdb) bt #0 0x00007f4d93129a32 in memcpy () from /lib64/libc.so.6 View on pastebin.com Preview by Yahoo In fake_req() from t_reply.c , the pointer shmem_msg->new_uri.s which is passed to memcpy becomes invalid. memcpy( faked_req->new_uri.s, shmem_msg->new_uri.s,faked_req->new_uri.len); (gdb) p shmem_msg->new_uri $3 = {s = 0x0, len = 0} If this bug is not supposed to be fixed in 4.2.0 , we can help with debugging . Regards, Dragos

AliasDB module & Forking
by Marino Mileti 05 Nov '14

05 Nov '14

Hi guys, i've implemented a parallel forking using aliasdb module. Everything is working good if the first client (first row in dbaliases table) in online. When I try to make a call to a specific number three clients rings together. If the first client isn't online no call is forwarded to other clients :( I know that with alias_db_lookup() the first record from DB is the new R-URI and the others are added like branches. But if the R-URI in unreachable how can try to call the other branches? This is location script.. if(alias_db_lookup("dbaliases")){ $sht(a=>$ci) = $sel(contact.uri); } $avp(oexten) = $rU; if (!lookup("location")) { $var(rc) = $rc; t_newtran(); switch ($var(rc)) { case -1: xlog("L_INFO","No contact found\n"); exit; case -3: send_reply("404", "Erorr"); exit; case -2: send_reply("405", "Method Not Allowed"); exit; } } Any suggest? My script still log "No contanct found" until timeout :( Many thanks ----- Marino Mileti -- View this message in context: http://sip-router.1086192.n5.nabble.com/AliasDB-module-Forking-tp132128.html Sent from the Users mailing list archive at Nabble.com.

REGISTRAR location replication (pua_reginfo)
by lejarreta.e＠sarenet.es 04 Nov '14

04 Nov '14

Good morning. We've got a problem with location memory and database replication between "n" kamailios as REGISTRAR servers. 1.- WHAT WE WANNA DO: - To have "n" Kamailios with their DB and memory "user location" replicated. - Each Kamailio owns its own DB.(It could be also with a common DB). - Each kamailio has a PUA_REGINFO, PRESENCE, and REGISTRAR roles. - USRLOC Module with db_mode = 2 (Write-Back scheme). 2.- WHAT WE DON'T WANNA DO: - USRLOC Module with db_mode != 2 (Write-Back scheme). 3.- BACKGROUND: - RFC3265 - RFC3680 - RFC3903 - I attach a small architecture graph. 4.- PROBLEMS: 4.1 Deadlock: Each REGISTER involves a NOTIFY to the other side. Each NOTIFY involves another NOTIFY to the other side. There should be a mechanism to avoid PUBLISH reginfo_handle_notify() function calls but to PUBLISH save() calls on pua_reginfo module. Any idea would be appreciated (also to workaround our problem). 4.2 PUA_REGINFO module notify.c Just FYI. We think It doesn't comply to RFC3680. It should observe "unkown-param" object to aid "Contact" header params such as "Path", "Received", "User_agent" and so on. We've changed code but for a fast startup we've also avoided "unkown-param" and now we're able to see replicated "Path", "Received ... params on each DB. Thanks and best regards. Eduardo Lejarreta.

"Help with dialog $dlg_var(cseq_diff)"
by Yuriy Gorlichenko 03 Nov '14

03 Nov '14

Hello. I need to increment CSeq value for INVITE with Auth params when use UAC_AUTH for outgoing calls to provider. Kamailio 4.2 may increment this using dialog module http://by-miconda.blogspot.de/2014/10/kamailio-42-tips-7-increment-cseq-for… Now I experements with this and var $dlg_var(cseq_diff) and at transaction way int have NULL value. I can not understand why My config is: # ----- dialog params modparam("dialog", "db_url",DBURL) modparam("dialog", "db_mode", 1) modparam("dialog","table_name","dialog") modparam("dialog", "dlg_flag", 4) modparam("dialog", "initial_cbs_inscript", 1) modparam("dialog", "profiles_with_value", "caller") modparam("dialog", "default_timeout", 60) modparam("dialog", "track_cseq_updates", 1) route config is at request route if(is_method("INVITE") && !has_totag()){ $dlg_ctx(timeout_route) = "DIALOG_END"; $dlg_ctx(timeout_bye) = 1; dlg_manage(); xlog("L_INFO","Dialog manage is {$ct}\n"); } } t_relay(); next I handle failure reply because 407 reply is recieved failure_route[MANAGE_FAILURE] { route(NATMANAGE); if (t_check_status("401|407")){ xlog("L_INFO", "Reply from provider on failure: $tU"); xlog("L_ERR","401/407 - Unauthorized.

So I can not understand why? What wrong I do? Thanks for advice.

Problems using htable iterator
by Glenn Larsen 03 Nov '14

Hi, I have a hard time using the htable iterator... I have this simple setup: modparam("htable", "htable", "h1=>size=4") ... sht_iterator_start("i1", "h1"); while (sht_iterator_next("i1")) { xlog("L_ERR", " SS: $shtitkey(i1) and $shtitval(i1)\n"); } sht_iterator_end("i1"); ... Now to put some simple data, I use: # sudo kamcmd htable.sets h1 test 123 # sudo kamcmd htable.dump h1 { entry: 8 size: 1 slot: { item: { name: test value: 123 } } } When the route is "executed", I get this in my log file: Nov 3 15:16:47 beast /sbin/kamailio[24865]: ERROR: SS: <null> and <null> The $shtitkey(i1) and $shtitval(i1) is always null.

rtpengine does not send RTP packets out
by Juan Perez 03 Nov '14

03 Nov '14

Hi, I have kamilio-4.2 and rtpengine running on the same machine.I have this scenario: softphone --> Kamailio with Rtpengine --> AsteriskThe softphone initiates the call, it is sent to the Asterisk. I can see the SDPs being re-written with the new IP/Ports provided by rtpengine: Invite from Kamailio to Asterisk200 Ok from Kamailio to Softphone However, I take a signaling/media capture on the server where the kamailio/rtpengine are running and see the RTP coming from both endpoints (softphone and asterisk) to the correct ports but there is no packets coming out from the proxy to either direction. I see these 2 lines on the rtpengine log and make me think that something prevents the rtpengine to stream out to the 2 endpoints: Nov 1 18:59:26 ip-10-0-2-68 rtpengine[27764]: [0866b358-dc9c-1232-1399-3767db69b8dd port 35038] Write error on RTP socket Nov 1 18:59:26 ip-10-0-2-68 rtpengine[27764]: [0866b358-dc9c-1232-1399-3767db69b8dd port 35038] Final packet stats: this is the log from the rtpengine: Nov 1 18:59:26 ip-10-0-2-68 rtpengine[27764]: Got valid command from 127.0.0.1:46686: offer - { "sdp": "v=0#015#012o=- 314474204173996793 6663595733338147866 IN IP4 99.153.161.148#015#012s=-#015#012c=IN IP4 99.153.161.148#015#012t=0 0#015#012m=audio 16386 RTP/AVP 114 0 8 101#015#012a=rtpmap:114 ilbc/8000#015#012a=fmtp:114 mode=30#015#012a=rtpmap:0 pcmu/8000#015#012a=rtpmap:8 pcma/8000#015#012a=rtpmap:101 telephone-event/8000#015#012a=fmtp:101 0-15#015#012", "direction": [ "pub", "pub" ], "replace": [ "origin", "session-connection" ], "call-id": "0866b358-dc9c-1232-1399-3767db69b8dd", "received-from": [ "IP4", " ...
