[kamailio/kamailio] Wishlist #234: URI transformation to pick up URI scheme (#592)
by Olle E. Johansson 16 Aug '17

16 Aug '17

I would like the URI transformations to be more generic so one can pick up the URI scheme, like HTTP: or TEL: Just an idea --- You are receiving this because you are subscribed to this thread. Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/592

[kamailio] PID file permissions (#231)
by Arsen 26 Jul '17

26 Jul '17

ENV: Debian 8 So on most Linux systems the /var/run folder is a tmpfs and after which clears after each reboot As I try to start up kamailio after a reboot through kamctl I get the following error. "ERROR: PID file /var/run/kamailio.pid does not exist -- Kamailio start failed" Because kamailio does not have the permission to write to the /var/run folder as the kamailio user. Would it be possible to add in the "kamctl" code a section where the SPECIFIED PID LOCATION (/var/run/kamailio) is checked and if it does not exist create it as the root user and chown it to the SPECIFIED USER (kamailio)? The way I have patched it for now is to create a init script that creates a /var/run/kamailio folder and chmods it to kamailio:kamailio Thanks everyone! --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/231

[kamailio/kamailio] "shm_mem_size" does not work if it was set in config file (#950)
by Maxim Malygin 25 Apr '17

25 Apr '17

### Description Config file has parameter "shm_mem_size" (or "shm" or "shm_mem") which allows to set shared memory size (in Mb) via configuration file. This parameter worked well in 3.1.5. Now it does not work (4.4.2). Shared memory size is always 64Mb (default value). The only way to set another size is to use "-m" command line option. #### Reproduction - Set shm_mem_size=512 in configuration file - Start kamailio and check size of shared memory using "kamcmd core.shmmem" - Expected result: total size of shared memory should be 512 Mb (in bytes) - Actual result: 64Mb ### Possible Solutions A workaround is to use "-m" command line option to send shared memeory size. ### Additional Information version: kamailio 4.4.3 (x86_64/linux) 5a2195 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: 5a2195 compiled on 13:41:22 Sep 27 2016 with gcc 4.4.7 OS: CentOS 6.8 (kernel 2.6.32-642.4.2.el6.x86_64) -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Kamailio crashes when it receives a 404 reply to an INVITE originated after a 302. (#875)

Hi, Kamailio crashes when we handle a 302 redirect and the reply is a 404. > # kamailio -v > version: kamailio 4.4.4 (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 4.9.2 root@14cn5:/home/joel/files# This works: > softphone1 > kamailio1 > server1 > 302 > kamailio1 > server2 > 200 OK This crashes: > softphone1 > kamailio1 > server1 > 302 > kamailio1 > server2 > 404 Not Found I'm attaching debug logs, sip traces and the bt full from backtrace. IPs: > A.B.C.D = Kamailio IP > E.F.G.H = Softphone IP > I.J.K.L1 = dispatcher node1 > I.J.K.L2 = dispatcher node2 In the config we send INVITE requests to a dispatcher group (very simple config). Then, in failure_route we have: ``` if (t_check_status("302")) { xlog("L_NOTICE", "Redirecting to TestName: $T_rpl($ct) - M=$rm R=$ru ID=$ci\n"); get_redirects("*"); route(RELAY); } ``` And call get redirected to the address of the contact in the 302. If the new INVITE to that address gets a 200, all works, if that request gets a 404, Kamailio crashes. Please let me know if you need more info, this is 100% reproducible on our platform. Thank you!

[kamailio/kamailio] Enabling DMQ cause high CPU usage (#822)
by Soapnix 29 Mar '17

29 Mar '17

Hi all! We trying to use two instances of kamailio on FreeBSD, kamailio was build from master branch. If I enables DMQ, 2 threads (pids) start utilize CPU, less than minute it's up to 100% (on a both servers). At that time kamailio successful handle calls, dmq and usrloc replication wokrs fine. While trying to understand what happens I got this debug info - something happens and K. cycles on shed_yeld() func. All additional info I put into attachments: [gdb_output.txt](https://github.com/kamailio/kamailio/files/528881/gdb_outpu… [kamailio.log.gz](https://github.com/kamailio/kamailio/files/528879/kamailio… [kamailio.txt](https://github.com/kamailio/kamailio/files/528883/kamailio.tx… [kdump.txt.gz](https://github.com/kamailio/kamailio/files/528880/kdump.txt.g… [ktrace.out.gz](https://github.com/kamailio/kamailio/files/528878/ktrace.out… [top_output.txt](https://github.com/kamailio/kamailio/files/528882/top_outpu… -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Fix execinfo error in ims_dialog module (#996)
by Fabrice Fontaine 14 Mar '17

14 Mar '17

Currently, ims_dialog includes execinfo.h to use backtrace in the backtrace2str function. However, all calls to backtrace2str are commented so disable this function through "if 0" and comment the include on execinfo.h to allow the cross-compilation of the ims_dialog module as some libc's don't always have this header (uclibc-ng, musl) Signed-off-by: Fabrice Fontaine <fontaine.fabrice(a)gmail.com> You can view, comment on, or merge this pull request online at: https://github.com/kamailio/kamailio/pull/996 -- Commit Summary -- * Fix execinfo error in ims_dialog module -- File Changes -- M src/modules/ims_dialog/dlg_hash.c (4) -- Patch Links -- https://github.com/kamailio/kamailio/pull/996.patch https://github.com/kamailio/kamailio/pull/996.diff -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Dialog: Core dump when using dlg_set_timeout (#1011)
by Olle E. Johansson 14 Mar '17

14 Mar '17

dlg_set_timeout("2419200", $var(entry), $var(id)); The both $var's contains strings. If I enclose them with "" there's no segfault, but the var's doesn't seem to be parsed by dlg_set_timeout either. Doing this causes a seg fault when kamailio starts. Version 4.4.2 Will try to get a core dump, but not sure since this is a production system... -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] topos inserts comma separated Via in OK (#1005)
by dryvoip 10 Mar '17

10 Mar '17

### Description When using topos, Kamailio corrupts the Via header in the OK packet sent when responding to an INVITE. For example, the following is observed in the OK: Via: SIP/2.0/UDP 1.2.3.4:5065;rport=5065;branch=abc,SIP/2.0/UDP 2.3.4.5:5060;branch=bcd Expected behaviour is to correctly insert two separate Via headers, as in the original INVITE: Via: SIP/2.0/UDP 1.2.3.4:5065;rport=5065;branch=abc Via: SIP/2.0/UDP 2.3.4.5:5060;branch=bcd ### Troubleshooting When not loading topos.so, OK packet is passed as expected. #### Reproduction Place a call with a dialog where multiple Via headers are present with topos.so loaded. Fully reproducible every time. ### Possible Solutions topos.so should reconstruct the Via header properly by inserting a separate Via header for each comma separated value it stores in the database. ### Additional Information ``` version: kamailio 4.4.5 (x86_64/linux) f98162 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: f98162 compiled on 16:48:08 Jan 18 2017 with gcc 4.4.7 ``` -- You are receiving this because you are subscribed to this thread.
