panning for v3.2.2
by Daniel-Constantin Mierla 31 Jan '12

31 Jan '12

Hello, I would like to package 3.2.2 on the same day with IRC devel meeting announced in the previous email (if is is happening this month) -- it is getting close to 2 months since v3.2.1. If you are aware of issues, report them on bug tracker to see what can be done before 3.2.1. Cheers, Daniel -- Daniel-Constantin Mierla -- http://www.asipto.com http://linkedin.com/in/miconda -- http://twitter.com/miconda

xmlops/xpath access of multiple nodes
by Alex Balashov 30 Jan '12

30 Jan '12

Hi, I guess this is more of an xpath question than a Kamailio one, so forgive me. All the same, how does one deal with a document like this using $xml(...): <?xml version="1.0" encoding="utf-8" ?> <sheep> <lamb> ... </lamb> <lamb> ... </lamb> </sheep> Specifically, how do I access the second, third, Nth element with the same tag, but without knowledge of any unique identifying attributes? Is there a useful way to iterate through them in Kamailio route script? I would have thought something like this could work: $var(i) = 0; while(defined $xml(x=>xpath:/sheep/lamb[$var(i)])) { ... $var(i) = $var(i) + 1; } However, obviously, that's not it. So what's the right way to do it? My desire is to buffer data from these nodes into an AVP array. As you might guess, it's a route set over which I need to serially fork.

alias problem
by Stoyan Mihaylov 30 Jan '12

30 Jan '12

My whole configuration is: [Sip clients] < = > Kamailio 3.2 <=> Asterisk servers (behind Kamailio) Asterisk servers have only local IP addresses, and I use t_relay instead of forward. Kamailio runs on same server as rtpproxy. Everything is fine if clients connect to Kamailio with its IP address - global, or if they are behind Kamailio with local address. When clients connect to Kamailio using sip.ourcompany.com, then call (video also) is OK, but ACK and BYE do not work. BYE receives not here (404), and ACK die somewhere. I forward BYE and ACK in case when src_ip==$td to Asterisk server. If one of clients use IP - then calls initiated from it are OK (BYE/ACK - are going correctly - to Asterisk and to other client also). But calls from other client have problems with BYE and ACK. To use sip.ourcompany.com - I put: alias=sip.ourcompany.com route[ACKBYE] { #!ifdef WITH_PSTN if (is_method("BYE|ACK")) { xlog("L_ALERT","AB $rm $sht(forw=>$ft) $td"); if(src_ip==$td){ #I have to rewrite du - messages loop in Kamailio, I store in $sht(forw=>$ft) $du which I use during INVITE. $du=$sht(forw=>$ft); route(RELAY); exit; } xlog("L_ALERT","ACK,Bye Not me"); } #!endif return; }

exec_avp size limitation
by Gustavo Garcia Bernardo 30 Jan '12

30 Jan '12

Hi folks, I'm having problems with exec_avp because is truncating the output of the script executed. Looking at the code I see exec_avp is imposing a limit of MAX_URI_SIZE (1024) but I don't understand why. The limit should be the maximum size for an avp variable in my opinion. Regards, G.

memory leak fix on xcap_ auth.c
by laura testi 30 Jan '12

30 Jan '12

Hi Daniel, I'm sending you some memory leak fix we have found and fixed on modules/utils/xcap_ auth.c. The fixed memory leak is in pres_watcher_allowed (), and it is about the "xmlFreeDoc" that it's never called for the "xcap_tree" variable. We downloaded the source file from master branch and then we fixed it. You can find here the diff from original and new code and in attach both the original and the new files. diff -u a/modules/utils/xcap_auth.c b/modules/utils/xcap_auth.c --- a/modules/utils/xcap_auth.c +++ b/modules/utils/xcap_auth.c @@ -280,13 +280,15 @@ } node= get_rule_node(subs, xcap_tree); - if (node== NULL) + if (node== NULL){ + xmlFreeDoc(xcap_tree); return 0; - + } /* process actions */ actions_node = xmlNodeGetChildByName(node, "actions"); if (actions_node == NULL) { LM_DBG("actions_node NULL\n"); + xmlFreeDoc(xcap_tree); return 0; } LM_DBG("actions_node->name= %s\n", actions_node->name); @@ -294,6 +296,7 @@ sub_handling_node = xmlNodeGetChildByName(actions_node, "sub-handling"); if (sub_handling_node== NULL) { LM_DBG("sub_handling_node NULL\n"); + xmlFreeDoc(xcap_tree); return 0; } sub_handling = (char*)xmlNodeGetContent(sub_handling_node); @@ -302,6 +305,7 @@ if (sub_handling == NULL) { LM_ERR("Couldn't get sub-handling content\n"); + xmlFreeDoc(xcap_tree); return -1; } if (strncmp((char*)sub_handling, "block", 5) == 0) { @@ -325,10 +329,12 @@ else { LM_ERR("unknown subscription handling action\n"); xmlFree(sub_handling); + xmlFreeDoc(xcap_tree); return -1; } xmlFree(sub_handling); + xmlFreeDoc(xcap_tree); return 0; Kind Regards, laura

Kamailio TLS with intermediate CA certificates
by Daniel Pocock 30 Jan '12

30 Jan '12

I found that my TLS client was not happy because my server cert is signed by an intermediate root. A quick search in Google found other people mentioning the same problem, but no solution or documentation. I've had a quick look in the Kamailio source and I notice it is using the call: SSL_CTX_use_certificate_chain_file to load the certificate specified in tls.cfg with certificate=myserver.pem In practice, this means the intermediate certificates can be appended to myserver.pem and Kamailio will present them to the TLS client: Example: Trust heirarchy: trusted root - inter 1 - inter 2 - server.example.com.pem Construct the PEM file in this exact order: cat server.example.com.pem > chain-server.example.com.pem cat inter2.pem >> chain-server.example.com.pem cat inter1.pem >> chain-server.example.com.pem and then, in tls.cfg: certificate=chain-server.example.com.pem
