[kamailio/kamailio] usrloc keepalive does not work for TLS connections (Issue #3178)

by abrezinsky

### Description The keepalive (ka*) features of usrloc does not work for TLS connections (and probably TCP). If a TLS connection is registered, the keepalive code attempts to send OPTIONS packets to the endpoint using UDP. Additionally, a TCP/TLS connection is not re-used and the code attempts to create a new one each request. ### Troubleshooting #### Reproduction Enable keepalive and register a phone using TLS #### Log Messages Kamailio Host: 10.15.5.116 Phone: 10.15.5.117 Phone is registered and seen in the registry ``` kamctl ul show { "jsonrpc": "2.0", "result": { "Domains": [{ "Domain": { "Domain": "location", "Size": 1024, "AoRs": [{ "Info": { "AoR": "anonymous", "HashID": 3819435025, "Contacts": [{ "Contact": { "Address": "sips:anonymous@10.15.5.117:5061", "Expires": 3531, "Q": -1, "Call-ID": "d06e987694afb559", "CSeq": 521595368, "User-Agent": "testclient/1.0", "Received": "[not set]", "Path": "[not set]", "State": "CS_NEW", "Flags": 0, "CFlags": 0, "Socket": "tls:10.15.5.116:5061", "Methods": 7903, "Ruid": "uloc-62c87f5c-1b6b-2", "Instance": "<urn:uuid:00000000-0000-1000-8000-0010492e1879>", "Reg-Id": 0, "Server-Id": 0, "Tcpconn-Id": 17, "Keepalive": 0, "Last-Keepalive": 1657310753, "KA-Roundtrip": 0, "Last-Modified": 1657310753 } }] } } ], "Stats": { "Records": 1, "Max-Slots": 1 } } }] }, "id": 14871 ``` When the keepalive code runs it shows the following: ``` Jul 8 14:27:52 localhost kamailio[6976]: 33(7012) DEBUG: usrloc [ul_keepalive.c:112]: ul_ka_urecord(): keepalive for aor: anonymous Jul 8 14:27:52 localhost kamailio[6976]: 33(7012) DEBUG: usrloc [ul_keepalive.c:235]: ul_ka_urecord(): keepalive request (len: 295) [[ Jul 8 14:27:52 localhost kamailio[6976]: OPTIONS sips:anonymous@10.15.5.117:5061 SIP/2.0 Jul 8 14:27:52 localhost kamailio[6976]: Via: SIP/2.0/UDP 10.15.5.116:5061;branch=z9hG4bKx.20.1.0 Jul 8 14:27:52 localhost kamailio[6976]: From: <sips:10.15.5.116:5061>;tag=uloc-62c87f5c-1b71-1-e3a7f411-62c88538-cc68d-14.1 Jul 8 14:27:52 localhost kamailio[6976]: To: <sip:anonymous@kamailio.org> Jul 8 14:27:52 localhost kamailio[6976]: Call-ID: ksrulka-20.1 Jul 8 14:27:52 localhost kamailio[6976]: CSeq: 80 OPTIONS Jul 8 14:27:52 localhost kamailio[6976]: Content-Length: 0 Jul 8 14:27:52 localhost kamailio[6976]: #015 Jul 8 14:27:52 localhost kamailio[6976]: ]] Jul 8 14:27:52 localhost kamailio[6976]: 33(7012) ERROR: <core> [core/udp_server.c:597]: udp_send(): sendto(sock, buf: 0x7fffe728ece0, len: 295, 0, dst: (10.15.5.117:5061), tolen: 16) - err: Bad file descriptor (9) ``` ### Possible Solutions There are 2 problems here. First, the address record does not have a transport defined. https://github.com/kamailio/kamailio/blob/a466d0b73a66b18419555eca437136f1b… at this point, `sdst.s` is "sips:anonymous@10.15.5.117:5061" so parse_uri returns a proto of `UDP`. If you override the value to "sips:anonymous@10.15.5.117:5061;transport=tls" then the code works as expected. The protocol is detected as TLS and the OPTIONS message generated later has the correct `Via` header. I'm not sure if the problem is that the address record is missing the transport, or if we need to infer the transport from the socket connection. The second issue is that the keepalive code doesn't re-use TCP/TLS connections. In the ul_ka_send() function ) all of the socket IDs hardcoded to '0' https://github.com/kamailio/kamailio/blob/a466d0b73a66b18419555eca437136f1b… This is easily fixable by adding in ``` if(uc->tcpconn_id) { idst.id = uc->tcpconn_id; } ``` to `ul_ka_urecord()` and removing all of the `kadst->id=0;` lines from the `ul_ka_send()` function. This works for in-memory during testing. I believe the tcpconn_id field needs to be set in ul_ka_db_records if you're returning it from the DB. I don't have an environment setup to test that. With those two changes made (hardcoding the transport and fixing the connection id) the keepalives are sent and work as expected: ``` 33(19413) DEBUG: usrloc [ul_keepalive.c:112]: ul_ka_urecord(): keepalive for aor: anonymous 33(19413) DEBUG: usrloc [ul_keepalive.c:169]: ul_ka_urecord(): MANUALLY OVERRIDING SDST: sips:anonymous@10.15.5.117:5061;transport=tls 33(19413) DEBUG: usrloc [ul_keepalive.c:247]: ul_ka_urecord(): keepalive request (len: 288) [[ OPTIONS sips:anonymous@10.15.5.117:5061 SIP/2.0 Via: SIP/2.0/TLS 10.15.5.116:5061;branch=z9hG4bKx.33.1.0 From: <sips:10.15.5.116:5061>;tag=uloc-62c8af83-4bd9-1-e3a7f411-62c8b37f-f2a22-21.1 To: <sip:anonymous@kamailio.org> Call-ID: ksrulka-33.1 CSeq: 80 OPTIONS Content-Length: 0 ]] 33(19413) DEBUG: <core> [core/tcp_main.c:1644]: _tcpconn_find(): found connection by id: 1 33(19413) DEBUG: <core> [core/tcp_main.c:2539]: tcpconn_send_put(): found fd in cache (4, 0x7fbaef193db8, 1) 33(19413) DEBUG: <core> [core/tcp_main.c:2761]: tcpconn_do_send(): sending... 33(19413) DEBUG: <core> [core/tcp_main.c:2794]: tcpconn_do_send(): after real write: c= 0x7fbaef193db8 n=317 fd=4 ``` I assume that we'd want to re-use a TCP/TLS connection but maybe that needs to be an option (ka_reuse_tcp) if other people are expecting the current behavior of creating a new connection for each new keepalive request. ### Additional Information ``` version: kamailio 5.7.0-dev0 (x86_64/linux) a466d0 flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, 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_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED 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: a466d0 compiled on 11:27:35 Jul 8 2022 with gcc 8.3.0 ``` * **Operating System**: Debian Buster -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3178 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] dialog: db and dmq issues in master branch (Issue #3218)

by shaneqld

### Description While debugging an issue in Kamailio 5.4, I compiled/installed master to see if the issue persists. However, I immediately ran into multiple issues with dialog in master: #### Using enable_dmq=1 With dmq enabled, I receive the following log lines which did not appear when running 5.4: ``` CRITICAL: dialog [dlg_timer.c:129]: insert_dlg_timer(): Trying to insert a bogus dlg tl=0x7fa0bc21fc80 tl->next=0x7fa0bbf46ba8 tl->prev=0x7fa0bbf46ba8 CRITICAL: dialog [dlg_dmq.c:314]: dlg_dmq_handle_msg(): Unable to insert dlg timer 0x7fa0bc21fc20 [2687:66928] ``` #### Using database When using database persistence (sqlite and db_mode=3 (SHUTDOWN)), dialogs are not persisted across restarts (which was working in 5.4). There are no obvious log lines, except when I end the call after restarting Kamailio I receive a "unable to find dialog for BYE" message which would be expected if the dialog did not persist. ### Troubleshooting - I ran the same configuration using 5.4 and neither issue occurred. - I attempted to identify the troublesome commit by checking out/compiling older commits based on the commit history of the dialog module, but could only go so far back until builds started failing with `module not found: modules/siprepo`. As such I was not able to identify when the behavior changed. #### Reproduction DMQ issue: Use dialog module with dmq enabled and start a call that has `dlg_manage();` in the path. My configuration has the following settings: ``` modparam("dmq", "server_address", SERVER_ADDRESS_DMQ) modparam("dmq", "notification_address", "redacted") modparam("dmq", "notification_address", "redacted") modparam("dmq", "num_workers", 6) modparam("dialog", "default_timeout", 14520) modparam("dialog", "profiles_with_value", "group") modparam("dialog", "enable_dmq", 1) modparam("dialog", "h_id_start", 0) modparam("dialog", "h_id_step", 16) ``` DB issue: Use dialog module with db enabled. Start a call that has `dlg_manage();` in the path and keep the call open. Observe `kamcmd dlg.list` shows the dialog. Restart kamailio. Observe `kamcmd dlg.list` no longer lists any dialogs. My configuration has the following additional settings: ``` modparam("dialog", "db_url", "sqlite:////kamailio/kamailio.sqlite") modparam("dialog", "db_mode", 3) ``` ### Additional Information **Kamailio Version** ``` version: kamailio 5.7.0-dev0 (x86_64/linux) f1dcb6 flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, 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_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED 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: f1dcb6 compiled on 23:18:23 Aug 15 2022 with gcc 8.3.0``` ``` **Operating System** ``` Distributor ID: Debian Description: Debian GNU/Linux 10 (buster) Release: 10 Codename: buster ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3218 You are receiving this because you are subscribed to this thread.
