[kamailio/kamailio] Microsoft Teams and Survivable Branch Appliance (SBA) (#2580)

by MarkMasiak

Support for Teams Survivable Branch Appliance Direct Routing Occasionally, a customer site using Direct Routing to connect to Microsoft Phone System may experience an internet outage. Assume that the customer site--called a branch--temporarily cannot connect to the Microsoft cloud through Direct Routing. However, the intranet inside the branch is still fully functional and users can connect to the Session Border Controller (SBC) that is providing PSTN connectivity. https://docs.microsoft.com/en-us/microsoftteams/direct-routing-survivable-b… -- -- You are receiving this because you are subscribed to this thread.

[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.
