[kamailio/kamailio] tcp_send_timeout not used on reused socket (Issue #3443)
by schoberw 13 Nov '23

13 Nov '23

### Description Having clients connected via TCP doing only passive connections in the kamailio server it seems the tcp_send_timeout is not used on messages going out to the clients. While tcp_keepalive is doing well as long as there was not sent any packet to the client tcp_send_timout does nothing. The underlying Linux tries to send the SIP message for ages (15 minutes in my case). Do I have a wrong understanding of tcp_send_timeout? I tried with tcp_async yes and no with same results. ### Troubleshooting These are my tcp settings: ``` # def = 10 Time in seconds after a TCP connection will be closed if it is not available for writing in this interval (and Kamailio wants to send something on it). # Lower this value for faster detection of broken TCP connections. tcp_send_timeout=3 tcp_connect_timeout=10 # def = 10 tcp_connection_lifetime=3605 tcp_rd_buf_size=32768 tcp_max_connections=2048 tcp_connection_match=1 # match also local port tcp_keepalive=yes # Enables keepalive for tcp (sets SO_KEEPALIVE socket option) tcp_keepcnt=3 # Number of keepalives sent before dropping the connection (TCP_KEEPCNT socket option). Linux only. tcp_keepidle=30 # Time before starting to send keepalives, if the connection is idle (TCP_KEEPIDLE socket option). Linux only. tcp_keepintvl=10 # Time interval between keepalive probes, when the previous probe failed (TCP_KEEPINTVL socket option). Linux only. tcp_async=yes # alias tcp_buf_write, default=yes tcp_crlf_ping=no ``` I also tried to set the tcp_send_timeout to much too high value 333666 to trigger this line of code in tcp_options.c: ``` WARN("%s: timeout too big (%u), the maximum value is %u\n", name, *to, max_val); ``` But even in -d -d -d debugging that line never hits. I do **not** make any connections outbound (senseless on NAT). Instead I'd like to reject this: ``` if ($dP =~ "tcp") { set_forward_no_connect(); xlog("L_INFO", ">> checking tcp connection to $dd:$dp"); if(tcp_get_conid("$dd:$dp", "$var(conid)")) { xlog("L_INFO", ">> connection id to $dd:$dp is: $var(conid)"); } else { xlog("L_ERR", ">> connection to $dd:$dp is no longer connected. Client must reregister!"); sl_send_reply("480", "TCP not connected"); exit; } } ``` But the connection ID is still there for a long time. And there are no keepalives done since the outgoing packets are in the queue. #### Reproduction 1. Register a client with TCP. 2. Pull the plug. 3. Make a call to it. 4. Run a `'watch 'netstat -tapen | grep <client_ip>'`: The connected client never vanishes. 5. Run a `tcpdump -i ethX tcp port <kamailio_server_port>`: the system tries to send the packet for a long time #### Log Messages There is not much to see in the log, even in debug level. `/usr/sbin/kamailio -P /var/run/kamailio/kamailio.sbc.pid -f /etc/kamailio.sbc/kamailio.cfg -m 48 -M 24 -u kamailio -g kamailio -d -d -d` At that moment the switchport was already shutdown: ``` May 9 10:48:19 p01t-1 kamailio.sbc[150273]: INFO: sbc:<script>: Network sending: >>>>>>>>>>>>>>>>>>>>>>>>>>>>>> INVITE sip:22@ws2.domain.tld;user=phone SIP/2.0 Record-Route: <sip:192.168.48.131:5065;r2=on;lr;ftag=97p54nlxgb;x-rtpp=1> Record-Route: <sip:10.101.65.131:5082;r2=on;lr;ftag=97p54nlxgb;x-rtpp=1> Via: SIP/2.0/UDP 192.168.48.131:5065;branch=z9hG4bKe01f.07e0d03fb0af18dcdb76154be67bea1d.0 Via: SIP/2.0/UDP 192.168.41.57:48310;received=10.101.65.130;branch=z9hG4bK-nzdt1be9c4xn;rport=48310 From: "01/301102-21" <sip:15553010221@ws2.domain.tld>;tag=97p54nlxgb To: <sip:22@ws2.domain.tld;user=phone> Call-ID: 3136383336323230393839333336-jg7spjsktbm2 CSeq: 2 INVITE Max-Forwards: 69 User-Agent: snomD765/10.1.49.11 Contact: <sip:15553010221@192.168.48.131:5065;ntv3=2;alias=10.101.65.130~48310~1;fs=udp:10.101.65.131:5082;uri=sip:15553010221%40192.168.41.57:48310%3bline%3dbq029ivo;line=bq029ivo>;reg-id=1 Accept: application/sdp Allow: INVITE, ACK, CANCEL, BYE, REFER, OPTIONS, NOTIFY, SUBSCRIBE, PRACK, MESSAGE, INFO, UPDATE Allow-Events: talk, hold, refer, call-info Supported: timer, 100rel, replaces, from-change Session-Expires: 3600 Min-SE: 90 Proxy-Authorization: Digest username="45487cfdffef4777",realm="ws2.domain.tld",nonce="d84c8d657ba6e3081547bbb6e0c1817c",uri="sip:22@ws2.domain.tld;user=phone",qop=auth,nc=00000001,cnonce="6be15ae9",response="9455eafa4f6b2b78e971a87cb2716132",opaque="485307819b9fa9a1f7e2ca58ae77f795",algorithm=MD5 Content-Type: application/sdp Content-Length: 258 P-Charging-Vector: icid-value=31363833363232;icid-generated-at=c5sbcp01t X-User: <sip:45487cfdffef4777@ws2.domain.tld> X-Location: dev.DefaultGroup;reg=192.168.48.68:5060;sig=192.168.48.74:5060;bt=0 X-Realm: p01t v=0 o=root 711904586 711904586 IN IP4 10.101.65.133 s=call c=IN IP4 10.101.65.133 t=0 0 m=audio 10490 RTP/AVP 9 8 101 a=rtpmap:9 G722/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=sendrecv a=rtcp:10491 a=ptime:20 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>> May 9 10:48:19 p01t-1 kamailio.sbc[150273]: DEBUG: sbc:tm [t_funcs.c:373]: t_relay_to(): new transaction forwarded May 9 10:48:19 p01t-1 kamailio.sbc[150273]: DEBUG: sbc:<core> [core/receive.c:528]: receive_msg(): request-route executed in: 45584 usec May 9 10:48:19 p01t-1 kamailio.sbc[150273]: DEBUG: sbc:<core> [core/usr_avp.c:637]: destroy_avp_list(): destroying list (nil) May 9 10:48:19 p01t-1 kamailio.sbc[150273]: DEBUG: sbc:<core> [core/usr_avp.c:637]: destroy_avp_list(): destroying list (nil) May 9 10:48:19 p01t-1 kamailio.sbc[150273]: DEBUG: sbc:<core> [core/usr_avp.c:637]: destroy_avp_list(): destroying list (nil) May 9 10:48:19 p01t-1 kamailio.sbc[150273]: DEBUG: sbc:<core> [core/usr_avp.c:637]: destroy_avp_list(): destroying list (nil) May 9 10:48:19 p01t-1 kamailio.sbc[150273]: DEBUG: sbc:<core> [core/usr_avp.c:637]: destroy_avp_list(): destroying list (nil) May 9 10:48:19 p01t-1 kamailio.sbc[150273]: DEBUG: sbc:<core> [core/usr_avp.c:637]: destroy_avp_list(): destroying list (nil) May 9 10:48:19 p01t-1 kamailio.sbc[150273]: DEBUG: sbc:<core> [core/xavp.c:541]: xavp_destroy_list(): destroying xavp list (nil) May 9 10:48:19 p01t-1 kamailio.sbc[150273]: DEBUG: sbc:<core> [core/xavp.c:541]: xavp_destroy_list(): destroying xavp list (nil) May 9 10:48:19 p01t-1 kamailio.sbc[150273]: DEBUG: sbc:<core> [core/xavp.c:541]: xavp_destroy_list(): destroying xavp list (nil) May 9 10:48:19 p01t-1 kamailio.sbc[150273]: DEBUG: sbc:<core> [core/receive.c:628]: receive_msg(): cleaning up May 9 10:48:19 p01t-1 kamailio.sbc[150273]: DEBUG: sbc:<core> [core/parser/sdp/sdp.c:863]: free_sdp(): _sdp = 0x7fa8d478c728 May 9 10:48:19 p01t-1 kamailio.sbc[150273]: DEBUG: sbc:<core> [core/parser/sdp/sdp.c:865]: free_sdp(): sdp = 0x7fa8d44ef100 May 9 10:48:19 p01t-1 kamailio.sbc[150273]: DEBUG: sbc:<core> [core/parser/sdp/sdp.c:867]: free_sdp(): session = 0x7fa8d44ee018 ...

[kamailio/kamailio] app_ruby: print backtrace when ruby exception occurs (#1766)
by Fatih Orhan 13 Nov '23

13 Nov '23

### Description Hello, When there is an error in my ruby script, app_ruby prints exception message without a stack trace, like this: ``` Dec 14 16:25:17 servername /usr/sbin/kamailio[24313]: ERROR: app_ruby [app_ruby_api.c:105]: app_ruby_print_last_exception(): exception: wrong number of arguments (1 for 2..3) Dec 14 16:25:17 servername /usr/sbin/kamailio[24313]: ERROR: app_ruby [app_ruby_api.c:1078]: app_ruby_run_ex(): ruby exception (6) on callback for: ksr_request_route (res type: 17) ``` Altough this message tells what is the error, it doesn't tell **where** the error happened, so it's hard to find the source of the problem. In ruby, exceptions have _backtrace()_ method returning stack trace as an array of strings. It would be really helpful if app_ruby also call this method and append its result to error message. ### Reproduction in kamailio.cfg ``` loadmodule "app_ruby.so" modparam("app_ruby", "load", "/etc/kamailio/ruby/routes.rb") cfgengine "ruby" ``` in /etc/kamailio/ruby/routes.rb ``` def some_method(param1, param2) end def ksr_request_route some_method(1) end ``` ### Expected behavior ``` Dec 14 16:46:24 servername /usr/sbin/kamailio[24314]: ERROR: <core> [core/kemi.c:87]: sr_kemi_core_err(): wrong number of arguments (1 for 2): /etc/kamailio/ruby/routes.rb:1:in `some_method' /etc/kamailio/ruby/routes.rb:4:in `ksr_request_route' ``` #### Actual observed behavior ``` Dec 14 16:45:42 servername /usr/sbin/kamailio[24311]: ERROR: app_ruby [app_ruby_api.c:105]: app_ruby_print_last_exception(): exception: wrong number of arguments (1 for 2) ``` ### Possible Solutions Relevant code seem to be here: https://github.com/kamailio/kamailio/blob/master/src/modules/app_ruby/app_r… I found example C code to print stack trace here but couldn't figure out how to integrate to app_ruby: http://zoo-project.org/svn/trunk/zoo-project/zoo-kernel/service_internal_ru… Equivalent ruby code would be (this code is not idiomatic, my aim is to provide C-like ruby code): ``` def some_error_generating_method method_taking_two_params(1) rescue => exception message = exception.to_s() + "\n" stack_trace = exception.backtrace() for line in stack_trace message = message + line + "\n" end print(message) end ``` ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.2.0 (x86_64/linux) 535e13 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_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 535e13 compiled on 10:26:34 Nov 28 2018 with gcc 4.8.5 ``` * **Operating System**: Centos 7.2 64bit ``` Linux servername 3.10.0-327.28.2.el7.x86_64 #1 SMP Wed Aug 3 11:11:39 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux ``` -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] kamailio depends on obsolete pcre3 library (Issue #2946)
by Victor Seva 26 Oct '23

26 Oct '23

>From https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1000134: ``` Source: kamailio Severity: important User: matthew-pcredep(a)debian.org Usertags: obsolete-pcre3 Dear maintainer, Your package still depends on the old, obsolete PCRE3[0] libraries (i.e. libpcre3-dev). This has been end of life for a while now, and upstream do not intend to fix any further bugs in it. Accordingly, I would like to remove the pcre3 libraries from Debian, preferably in time for the release of Bookworm. The newer PCRE2 library was first released in 2015, and has been in Debian since stretch. Upstream's documentation for PCRE2 is available here: https://pcre.org/current/doc/html/ Many large projects that use PCRE have made the switch now (e.g. git, php); it does involve some work, but we are now at the stage where PCRE3 should not be used, particularly if it might ever be exposed to untrusted input. This mass bug filing was discussed on debian-devel@ in https://lists.debian.org/debian-devel/2021/11/msg00176.html Regards, Matthew [0] Historical reasons mean that old PCRE is packaged as pcre3 in Debian ``` -- You are receiving this because you are subscribed to this thread.

Re: Performances issue when freeing shared memory in custom module (Kamailio 5.5.2)
by Henning Westerholt 04 Aug '23

04 Aug '23

Hello, (Adding sr-dev to CC) This looks indeed a bit strange. Do you get any error messages in the log? In which process you are freeing the memory, one of the worker processes or the RPC process? You could also try to use another memory manager to see if you get better performance. There is a command line parameter to choose one during startup. Cheers, Henning -- Henning Westerholt - https://skalatan.de/blog/ Kamailio services - https://gilawa.com<https://gilawa.com/> From: Chaigneau, Nicolas <nicolas.chaigneau(a)capgemini.com> Sent: Wednesday, January 18, 2023 6:49 PM To: Kamailio (SER) - Users Mailing List <sr-users(a)lists.kamailio.org> Subject: [SR-Users] Performances issue when freeing shared memory in custom module (Kamailio 5.5.2) Hello, I'm encountering performance issues with Kamailio (5.5.2). I'm using a custom Kamailio module that loads routing data in memory, using Kamailio shared memory. This routing data is very large. It can be fully reloaded through a Kamailio RPC command (which is done once each day). When reloading, two sets of data are maintained, one "loading" and another "current" (the latter being used to handle SIP requests). When loading of the new data is finished, it is swapped to "current". Then, memory of the old (now unused) data is freed. I've noticed that when Kamailio is freeing the old data, there is a very significant performance impact on SIP requests. This is surprising to me, because the SIP requests do not use this old data. This is not a CPU issue, idle CPU% is at about 99% at that moment. I'm using the following functions : - shm_mallocxz - shm_free From what I understand, shm_free is actually "qm_shm_free" defined in "src\core\mem\q_malloc.c" (the default shared memory manager being "qm"). I've noticed that there is also a variant shm_free_unsafe ("qm_free"), which does not perform locking. I'm wondering if the lock could be the cause of my performances issues ? (But I'm not sure how this could be possible, because although the SIP requests need to access the shared memory allocated, they do not use directly the functions from the share memory manager.) If the performances issues are causes by the lock, could I use the unsafe version "safely" ? (considering that it is guaranteed that the old data cannot be used by anyone else) Thanks for your help.
