[kamailio] PID file permissions (#231)

by Arsen

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

Outbound flow failure handling merged to master

by Hugh Waite

Hello, As you will see I have merged my branch back into master. These changes add a new event route [tm:branch-failure] to the tm module which is run when any failure response is received on a transaction. The event_route uses a new route type BRANCH_ROUTE which limits the functions that can be run in the route. The functions t_check_status(), t_next_contact_flow(), t_relay() and unregister() can be used in this route. A new pv $T_reply_ruid is accessible in this route which can be used to unregister a single contact entry. The following example route can be used on a registrar to handle failed or invalid flows: event_route[tm:branch-failure] { xlog("L_INFO", "event_route[tm:branch-failure]\n"); if (t_check_status("430|403")) { if (!unregister("location", "$tu", "$T_reply_ruid")) { xlog("L_WARN", "failed to unregister $tu with ruid $T_reply_ruid\n"); } if (!t_next_contact_flow()) { xlog("L_INFO", "No more flows\n"); } else { xlog("L_INFO", "Next flow\n"); t_relay(); } } } Any bugs, memory leaks etc. let me know!

[kamailio] pua: E_Tag miss match due to race between consecutive PUBLISH requests (#21)

by Ovidiu Sas

If a PUBLISH request is sent before a 200 OK for the previous PUBLISH request is received, the E-Tag is reset which leads to inconsistent presentity data in the presence server. This is happening because the second PUBLISH is sent with the same E-Tag as the previous one, but the presence server has an updated the E-Tag (generated while handling the first PUBLISH). The pua module should implement a queuing mechanism for subsequent PUBLISH request while a previous PUBLISH transaction is in progress. No new PUBLISH requests should be sent before a response to the previous PUBLISH request was received and the E-Tag updated. --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/21

[kamailio] uac module (uac_req_send, register) doesn't do failover (#210)

by Alex

Requests send with uac module's functions like uac_req_send() and remote registrations use the TM module, but don't actually do (DNS) failover when a destination is unreachable or sends a 503. In the tm's uac.c, t_uac_prepare() function, i can already see that the dns handle is stored in a throwaway variable instead of in the transaction, but fixing the issue isn't as simple as just storing it in the transaction (print_uac_request_from_buf() needs a uas in the transaction). Due to github not supporting attachments to issues, the sample config and debug log are inline.... :( DNS entry: ``` $ host -t SRV _sip._udp.failover.test.speakup.nl _sip._udp.failover.test.speakup.nl has SRV record 10 0 1111 try1.test.speakup.nl. _sip._udp.failover.test.speakup.nl has SRV record 100 0 2222 try2.test.speakup.nl. ``` Log snippet: ```syslog Jun 15 10:00:03 rio UACFailover[18178]: INFO: <script>: Sending OPTIONS request to sip:failover.test.speakup.nl Jun 15 10:00:03 rio UACFailover[18178]: DEBUG: tm [uac.c:249]: t_uac_prepare(): DEBUG:tm:t_uac: next_hop=<sip:failover.test.speakup.nl> Jun 15 10:00:03 rio UACFailover[18178]: DEBUG: <core> [dns_cache.c:537]: _dns_hash_find(): (_sip._udp.failover.test.speakup.nl(34), 33), h=825 Jun 15 10:00:03 rio UACFailover[18178]: DEBUG: <core> [resolve.c:937]: get_record(): skipping 8 NS (p=0x9ea284, end=0x9ea3e9) Jun 15 10:00:03 rio UACFailover[18178]: DEBUG: <core> [resolve.c:952]: get_record(): parsing 9 ARs (p=0x9ea335, end=0x9ea3e9) Jun 15 10:00:03 rio UACFailover[18178]: DEBUG: <core> [dns_cache.c:1741]: dns_get_related(): (0x7f225233eb38 (_sip._udp.failover.test.speakup.nl, 33), 33, *0x7f2257baf2b8) (0) Jun 15 10:00:03 rio UACFailover[18178]: DEBUG: <core> [dns_cache.c:840]: dns_cache_add_unsafe(): adding _sip._udp.failover.test.speakup.nl(34) 33 (flags=0) at 825 Jun 15 10:00:03 rio UACFailover[18178]: DEBUG: <core> [dns_cache.c:840]: dns_cache_add_unsafe(): adding try1.test.speakup.nl(20) 1 (flags=0) at 310 Jun 15 10:00:03 rio UACFailover[18178]: DEBUG: <core> [dns_cache.c:840]: dns_cache_add_unsafe(): adding try2.test.speakup.nl(20) 1 (flags=0) at 307 Jun 15 10:00:03 rio UACFailover[18178]: DEBUG: <core> [dns_cache.c:2336]: dns_srv_get_nxt_rr(): (0x7f225233eb38, 0, 0, 1597643831): selected 0/1 in grp. 0 (rand_w=0, rr=0x7f225233eba0 rd=0x7f225233ebb8 p=10 w=0 rsum=0) Jun 15 10:00:03 rio UACFailover[18178]: DEBUG: <core> [dns_cache.c:537]: _dns_hash_find(): (try1.test.speakup.nl(20), 1), h=310 Jun 15 10:00:03 rio UACFailover[18178]: DEBUG: <core> [dns_cache.c:2926]: dns_a_resolve(): (try1.test.speakup.nl, 0) returning 0 Jun 15 10:00:03 rio UACFailover[18178]: DEBUG: <core> [dns_cache.c:3169]: dns_srv_resolve_ip(): ("_sip._udp.failover.test.speakup.nl", 0, 0), ret=0, ip=192.168.1.245 Jun 15 10:00:03 rio UACFailover[18178]: DEBUG: <core> [dns_cache.c:3260]: dns_srv_sip_resolve(): (failover.test.speakup.nl, 0, 0), srv0, ret=0 Jun 15 10:00:03 rio UACFailover[18178]: DEBUG: tm [uac.c:150]: dlg2hash(): DEBUG: dlg2hash: 54501 Jun 15 10:00:03 rio UACFailover[18178]: DEBUG: tm [uac.c:351]: t_uac_prepare(): executing event_route[tm:local-request] Jun 15 10:00:03 rio UACFailover[18178]: DEBUG: <core> [parser/msg_parser.c:606]: parse_msg(): SIP Request: Jun 15 10:00:03 rio UACFailover[18178]: DEBUG: <core> [parser/msg_parser.c:608]: parse_msg(): method: <OPTIONS> Jun 15 10:00:03 rio UACFailover[18178]: DEBUG: <core> [parser/msg_parser.c:610]: parse_msg(): uri: <sip:failover.test.speakup.nl> Jun 15 10:00:03 rio UACFailover[18178]: DEBUG: <core> [parser/msg_parser.c:612]: parse_msg(): version: <SIP/2.0> Jun 15 10:00:03 rio UACFailover[18178]: DEBUG: <core> [parser/parse_via.c:1254]: parse_via_param(): Found param type 232, <branch> = <z9hG4bK5e4d.47adbbf5000000000000000000000000.0>;

[kamailio] Lots of tcp_read_* errors in log, multi-transport server, lack of context in messages (#385)

by Andrey Utkin

Hi devs, The logs of our Kamailio servers are rich for such lines: ``` Oct 28 06:57:35 ip-172-31-0-139 /usr/local/sbin/kamailio[31963]: ERROR: <core> [tcp_read.c:271]: tcp_read_data(): error reading: Connection reset by peer (104) Oct 28 06:57:35 ip-172-31-0-139 /usr/local/sbin/kamailio[31963]: ERROR: <core> [tcp_read.c:1296]: tcp_read_req(): ERROR: tcp_read_req: error reading ``` The servers serve WS, WSS, UDP, TCP and TLS as connection transports. So we cannot figure what happens and if this is really a problem, but we get accused by whoever audits the servers. What could be done to make this more trackable? Or maybe these messages should be suppressed, if there's no way to track them and they don't mean any problem? --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/385
