[kamailio] kex: per module memory debugging (#225)
by Stefan Mititelu 02 Nov '15

02 Nov '15

Kex module updated to also give some details about memory used by each module. Changed f_*, q_* and tlsf_* memory stubs to also include the module name. Added 2 new memory API functions(for each of the memory algos) which will iterate throughout the memory fragments and agregate the memory size used by each function in order to print it. Tested with MEMMNG=0,1,2 and MEMDBG=0,1. Use "kamcmd mem.stat mod_name pkg/shm/all" to test Updated doku.

[kamailio] Proposed: Consolidate example kamailio.cfg files (#209)
by tuxd00d 20 Oct '15

20 Oct '15

- There are relatively few differences between the example configuration files. - The time needed to maintain three separate files doesn't match the benefit. - The power of the #!define and #!ifdef system negates the need for separate examples. - It is simple enough to remove #!ifdef sections if one wishes to slim down the file size. - I'll do a consolidation if no valid argument against it is raised. --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/209

[kamailio] nathelper sending keep alives on nodes where contact replicated using dmq_usrloc (#310)
by 00Asgaroth00 19 Oct '15

19 Oct '15

I have 3 registrars being replicated to each other using dmq_usrloc. These registrars sit behind proxy servers. I use the path header to specify the received address. When the nathelper module is enabled, the nathelper then sends keep alive options messages from all three registrars for the same contact instead of the node that processed the original registration. I am using in-memory replication (db_mode = 0), so the server_id core parameter does not seem to be taking affect for in-memory replication, i believe this is only for database mode only. I currently have server_id set differently for each registrar, to no effect. nathelper module configuration parameters are as follows: ``` modparam("nathelper", "natping_interval", 20) modparam("nathelper", "natping_processes", 4) modparam("nathelper", "ping_nated_only", 1) modparam("nathelper", "sipping_from", "sip:keepalive@domain.com") modparam("nathelper", "sipping_method", "OPTIONS") modparam("nathelper", "force_socket", NAT_PING_SOCKET) ``` NAT_PING_SOCKET is set to the local interface of each registrar where I want the message to originate from: ``` # Registrar01 #!define NAT_PING_SOCKET "10.7.0.170:5060" # Registrar02 #!define NAT_PING_SOCKET "10.7.0.171:5060" # Registrar03 #!define NAT_PING_SOCKET "10.7.0.172:5060" ``` server_id is set for each registrar ``` # Registrar01 server_id=001 # Registrar02 server_id=002 # Registrar03 server_id=003 ``` I noticed that when the force_socket is set and a registration is sent from a node that did not process the request, then an options messages is sent via the forced_socket but the originating IP is that of the primary interface of the node, in this case, the kamailio listening address on the 10.6.0.0/24 segment, and example message follows: ``` 12:42:13.320519 00:50:56:91:5e:77 > 00:50:56:91:64:fe, ethertype IPv4 (0x0800), length 455: (tos 0x60, ttl 64, id 62009, offset 0, flags [none], proto UDP (17), length 441) 10.6.0.170.sip > 10.7.0.109.sip: [udp sum ok] SIP, length: 413 OPTIONS sip:subscriber01@172.16.0.138:5060;alias=78.143.152.30~49233~1 SIP/2.0 Via: SIP/2.0/UDP 10.6.0.170:5060;branch=0 Route: <sip:10.7.0.109;lr;received=sip:78.143.152.30:49233> From: sip:keepalive@domain.com;tag=uloc-3-55e0473b-1503-af38-6cf5fbae-864c1976 To: sip:subscriber01@172.16.0.138:5060;alias=78.143.152.30~49233~1 Call-ID: 9f855711-a24ef866-112a3d5(a)10.6.0.170 CSeq: 1 OPTIONS Content-Length: 0 ``` The MAC address above confirms that the sending interface is that of force_socket for nathelper, but the source IP address is that of the primary interface of the registrar. This results in martian source messages on the target proxy server: ``` Aug 31 12:42:13 proxy01 kernel: martian source 10.7.0.109 from 10.6.0.170, on dev eth1 Aug 31 12:42:13 proxy01 kernel: ll header: 00:50:56:91:64:fe:00:50:56:91:5e:77:08:00 ``` I suspect the latter issue (martian source) will resolve itself if the registrar not processing the registration stops sending nathelper keep alive messages for contacts it did not itself process. Please let me know if you require any additional information from me to debug this issue further. --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/310

[kamailio] tm: fake msg and environment to append new branches (#346)
by Federico Cabiddu 07 Oct '15

07 Oct '15

This fix try to solve the crash reported in http://lists.sip-router.org/pipermail/sr-users/2015-September/089846.html. The cause of the crash was that the sip message used to append branch was the shmem clone of the original message. When the new branches were going through their configured branch route, modifications done by other modules' function (like rtpproxy) were applied to this stored copy directly, causing the crash once a failure route was run. This patch take the same approach as the failure handler one, creating a fake request from the origin message and using this one to append branches. I am not sure if this is a good approach, since the appended branch are going through the branch route and some function called there could not be compatible with a faked request.

[kamailio] Building a json/rest module (#318)
by Laurent Debacker 06 Oct '15

06 Oct '15

Any plans to build a json/rest over http module? There is such a module over rpc, but not over http. Could the http_query module be used as a basis for such a module? Potentially with https and basic authentication? --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/318

Install scripts and /var/run/kamailio
by Olle E. Johansson 01 Oct '15

01 Oct '15

Just a note so I don’t forget: When doing training we installed a few computers from tarballs, and got problems running the default script - install doesn’t seem to create /var/run/kamailio which is now a default for some options. We propably need to make sure this directory is created by standard install, not just by the RPM/DEB installs. /O
