[kamailio/kamailio] Kamailio not retrieving custom or default socket when sending timed REGISTER messages (#2262)

by kdanderso

### Description When using Kamailio in a multi-homed configuration to register with another device using the uac module, it does not retrieve the custom or default socket information for timed registration attempts. It does, however, use the custom/default socket data for the initial registration. #### Reproduction The network is configured for two addresses: 10.9.9.121/24 and 10.9.7.121/24. Two floating IP addresses are also assigned (via Pacemaker/Corosync): 10.9.9.120/24 and 10.9.7.120/24. For testing, all addresses can be assigned permanently, so it is not necessary to have Pacemaker/Corosync installed. MySQL database has a user in the uacreg table with the socket column set to udp:10.9.7.120:5060. kamailio.cfg includes the following to enable sending of REGISTER messages: mhomed = 1 listen=udp:10.9.9.120 listen=udp:10.9.7.120 #!define DBURL "mysql://kamailio:kamailiorw@10.9.9.101/kamailio" modparam("rr", "append_fromtag", 1); modparam("uac", "reg_db_url", DBURL); modparam("uac", "reg_contact_addr", "10.9.7.120:5060"); modparam("uac", "reg_keep_callid", 1); modparam("uac", "default_socket", "udp:10.9.7.120:5060"); modparam("uac", "reg_timer_interval", 30); #### Log Messages The initial REGISTER outputs the following log data. The registration completes successfully.

[kamailio/kamailio] Deadlocks after ungracefully terminated TLS connections (#2395)

by Laszlo

This bug report concerns a Kamailio instance that's functioning as an edge proxy, accepting requests from clients over TLS and forwarding them to internal components over UDP. I've observed occasional "deadlocks" that all take place after there were connectivity issues between Kamailio and one or more of the clients (logging messages such as "tcp_send failed", "handle_tcpconn_ev(): connect x failed", "tcp_read_data(): error reading: Connection reset by peer"). Environment: * Ubuntu 16.04 * Kamailio 5.2.7 (5.2.7+ubuntu16.04) Relevant config: ``` # for TLS clients socket_workers=10 listen=tls:wan.ip:TLS_PORT # to be able to forward incoming TCP requests to UDP destinations socket_workers=10 listen=udp:wan.ip:TLS_PORT # for RPC commands socket_workers=2 listen=tcp:127.0.0.1:HTTP_PORT ``` ## Reproduction After a lot of trial and error, I've found a way to somewhat reproducibly trigger the problem using sipp. It involves setting up a large amount of simultaneous calls dialing into the edge proxy using TLS, to a destination UA that will answer the call and keep it open for a few seconds, then using `ctrl-c` to suddenly quit sipp which will ungracefully terminate the TCP/TLS connections. It takes me a couple of iterations to trigger the problem, e.g repeat until Kamailio starts failing: * start sipp * terminate sipp with ctrl-c * (quickly) restart sipp * terminate sipp * etc The amount of simultaneous calls has to be sufficiently large. In my environment I'm unable to reproduce the problem at all with 10-20 calls, while 50 calls always triggers the problem after a couple of iterations. Example sipp commandline: `sipp -nd -sf caller.xml -d 2000 -r 50 -l 500 -m 5000 -max_socket 1000 -t ln -tls_cert cert.crt -tls_key key.key kamailio.edge.proxy:5061` ## Failure mode 1 In one of the failure modes, it appears that all available TCP/TLS workers are permanently bricked; sipp's calls will simply timeout and not trigger any dialplan handling. Interestingly, even though I have dedicated workers for TLS (SIP client) and TCP (RPC commands), and my reproduction scenario doesn't connect to the HTTP_PORT at all, this failure scenario bricks the TCP (RPC) listeners as well; any curl requests to it will simply timeout as well. Kamailio will hang for a while on (systemd) restart. ## Failure mode 2 In another failure mode, it looks like the TCP workers are unaffected but the UDP perform forwarding to UDP destinations are broken. Sipp's calls will enter Kamailio, but forwarding (`relay()`) to the next hop will timeout even though the destination is functioning just fine. Since this failure mode doesn't break RPC I was able to enable debug logging: ``` 2020-07-07T17:26:58.770411+02:00 kamailio[24056]: INFO: From Customer 2020-07-07T17:26:58.770697+02:00 kamailio[24056]: DEBUG: pv [pv_trans.c:590]: tr_eval_string(): i=0 j=2 2020-07-07T17:26:58.770971+02:00 kamailio[24056]: DEBUG: dispatcher [dispatch.c:2055]: ds_manage_routes(): set [4] 2020-07-07T17:26:58.771248+02:00 kamailio[24056]: DEBUG: dispatcher [dispatch.c:2161]: ds_manage_routes(): using alg [0] hash [250849449] 2020-07-07T17:26:58.771535+02:00 kamailio[24056]: DEBUG: dispatcher [dispatch.c:2205]: ds_manage_routes(): selected [0-4-0/1] <sip:wan.ip:8065> 2020-07-07T17:26:58.771817+02:00 kamailio[24056]: DEBUG: dispatcher [dispatch.c:2226]: ds_manage_routes(): using first entry [4/1] 2020-07-07T17:26:58.772090+02:00 kamailio[24056]: DEBUG: dispatcher [dispatch.c:2269]: ds_manage_routes(): using entry [4/0] 2020-07-07T17:26:58.772362+02:00 kamailio[24056]: DEBUG: dispatcher [dispatch.c:2016]: ds_select_dst_limit(): selected target destinations: 2 2020-07-07T17:26:58.773001+02:00 kamailio[24056]: DEBUG: pv [pv_core.c:2611]: pv_set_force_sock(): trying to set send-socket to [udp:wan.ip:5061] 2020-07-07T17:26:58.773353+02:00 kamailio[24056]: DEBUG: <core> [core/socket_info.c:559]: grep_sock_info(): checking if host==us: 13==13 && [wan.ip] == [wan.ip] 2020-07-07T17:26:58.773829+02:00 kamailio[24056]: DEBUG: <core> [core/socket_info.c:566]: grep_sock_info(): checking if port 5061 (advertise 0) matches port 5061 2020-07-07T17:26:58.774122+02:00 kamailio[24056]: NOTICE: Relaying (cid: 1-9151(a)sipp.ip). 2020-07-07T17:26:58.774417+02:00 kamailio[24056]: DEBUG: siputils [checks.c:120]: has_totag(): no totag 2020-07-07T17:26:58.774708+02:00 kamailio[24056]: DEBUG: tm [t_lookup.c:1344]: t_newtran(): msg (0x7f69d1cc4980) id=1265/24056 global id=1265/24056 T start=(nil) 2020-07-07T17:26:58.774989+02:00 kamailio[24056]: DEBUG: tm [t_lookup.c:499]: t_lookup_request(): start searching: hash=43232, isACK=0 2020-07-07T17:26:58.775315+02:00 kamailio[24056]: DEBUG: tm [t_lookup.c:457]: matching_3261(): RFC3261 transaction matching failed - via branch [z9hG4bK-9151-1-1] 2020-07-07T17:26:58.775612+02:00 kamailio[24056]: DEBUG: tm [t_lookup.c:682]: t_lookup_request(): no transaction found 2020-07-07T17:26:58.775908+02:00 kamailio[24056]: DEBUG: <core> [core/md5utils.c:67]: MD5StringArray(): MD5 calculated: 0a5d4a8d13f9606523da9c4d193b2261 2020-07-07T17:26:58.776270+02:00 kamailio[24056]: DEBUG: <core> [core/dns_cache.c:3197]: dns_srv_sip_resolve(): (wan.ip, 0, 0), ip, ret=0 2020-07-07T17:26:58.776701+02:00 kamailio[24056]: DEBUG: <core> [core/msg_translator.c:1765]: check_boundaries(): no multi-part body 2020-07-07T17:26:58.777012+02:00 kamailio[24056]: DEBUG: <core> [core/msg_translator.c:2935]: create_via_hf(): id added: <;i=a701>, rcv proto=3 2020-07-07T17:26:58.777596+02:00 kamailio[24056]: DEBUG: tm [t_funcs.c:375]: t_relay_to(): new transaction forwarded 2020-07-07T17:26:58.777948+02:00 kamailio[24056]: DEBUG: <core> [core/receive.c:354]: receive_msg(): request-route executed in: 1927 usec 2020-07-07T17:26:58.778243+02:00 kamailio[24056]: DEBUG: <core> [core/usr_avp.c:636]: destroy_avp_list(): destroying list (nil) 2020-07-07T17:26:58.779265+02:00 kamailio[24056]: message repeated 5 times: [ DEBUG: <core> [core/usr_avp.c:636]: destroy_avp_list(): destroying list (nil)] 2020-07-07T17:26:58.779431+02:00 kamailio[24056]: DEBUG: <core> [core/xavp.c:507]: xavp_destroy_list(): destroying xavp list (nil) 2020-07-07T17:26:58.779753+02:00 kamailio[24056]: DEBUG: <core> [core/receive.c:458]: receive_msg(): cleaning up 2020-07-07T17:27:00.705303+02:00 kamailio[24053]: DEBUG: tm [t_reply.c:1266]: t_should_relay_response(): ->>>>>>>>> T_code=0, new_code=408 2020-07-07T17:27:00.705917+02:00 kamailio[24053]: DEBUG: tm [t_lookup.c:1041]: t_check_msg(): msg (0x7f69b1017e80) id=1264/24056 global id=1264/24056 T start=0x7f69b10167c0 2020-07-07T17:27:00.706187+02:00 kamailio[24053]: DEBUG: tm [t_lookup.c:1116]: t_check_msg(): T (0x7f69b10167c0) already found for msg (0x7f69b1017e80)! 2020-07-07T17:27:00.706533+02:00 kamailio[24053]: DEBUG: tmx [t_var.c:539]: pv_get_tm_reply_code(): reply code is <408> 2020-07-07T17:27:00.706879+02:00 kamailio[24053]: DEBUG: tm [t_lookup.c:1041]: t_check_msg(): msg (0x7f69b1017e80) id=1264/24056 global id=1264/24056 T start=0x7f69b10167c0 2020-07-07T17:27:00.707198+02:00 kamailio[24053]: DEBUG: tm [t_lookup.c:1116]: t_check_msg(): T (0x7f69b10167c0) already found for msg (0x7f69b1017e80)! 2020-07-07T17:27:00.707522+02:00 kamailio[24053]: DEBUG: tmx [t_var.c:594]: pv_get_tm_reply_reason(): reply reason is [Request Timeout] { "DSC": "tcp receiver (tls:wan.ip:5061) child=0", "IDX": 14, "PID": 24056 }, { "DSC": "slow timer", "IDX": 11, "PID": 24053 }, ``` Kamailio will restart (systemd) normally and everything will function normally again afterwards. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Expand the list of required default 3rd party libraries for Kamailio (#969)

by Olle E. Johansson

(from devmeeting #Fosdem) - adding new dependencies as core dependencies - Curl - libssl - uuid - libunistring - libxml2 Any other candidates? They have to be libraries that are commonly installed on most Linux/Unix system. This would mean that a lot of more modules will be built by default, like TLS, HTTP_CLIENT, WEBSOCKET. We may also look over the names of the packages/groups for the build system and linux distros -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Kamailio on RHEL/Centos 8 issue with SCTP associations created towards endpoint's primary and secondary IP addresses (#2429)

by Piotr Grabowski

### Description Kamailio is unable to create a SCTP association to IP address that is reachable normally when dispatcher.list is configured as following: ``` 760320003 sip:10.59.144.2:5063;transport=sctp 9 0 dstid=1 760320003 sip:10.59.144.130:5063;transport=sctp 9 0 dstid=1 ``` 10.59.144.2 and 10.59.144.130 are IPs of same endpoint treated as primary and secondary, Kamailio can't send probe (OPTIONS requests) as SCTP association can't be created.

[kamailio/kamailio] uri_restore_rcv_alias() tried twice for local request (#2014)

by Alex Hermann

### Description While debugging an issue with locally generated in-dialog requests I stumbled upon some weirdness with the alias functionality from the nathelper module. The dialog modules tries to handle an alias parameter when sending an in-dialog request by calling ```uri_restore_rcv_alias()``` in the function ```build_dlg_t()```. A few instructions later, the same is attempted by the tm module in the function ```req_within()```. It seems to me that the attempt by the dialog module is redundant and can be removed. And while at it, IMHO it should be removed from the tm module too. This is functionality introduced by the nathelper module. Nowhere in the documentation it is mentioned there is some automatic handling of the alias parameter. If handling is needed for local requests, the script writer can call ```handle_uri_alias()``` from within local_route. If the functionality has to stay, may I suggest that the code in the nathelper module makes use of the ```uri_restore_rcv_alias()``` function instead of having its own duplicate implementation. Less maintenance, easier debugging. -- You are receiving this because you are subscribed to this thread.
