[kamailio/kamailio] Wrong Record-Route and Via header fields when TCP is used (#2033)

by leonid-xorcom

### Description Kamailio server has two legs that are connected to different networks. I'm using Kamailio v.5.2.3 and the "enable_double_rr" is implicitly set to "1". The leg "A" IP address is 10.28.80.1 The leg "B" IP address is 192.168.9.103 The call is initiated from 10.28.80.47 According to the "rr" module documentation, function record_route() should insert two "Record_Route" header fields when a request is accepted on one leg is should go out via the second leg. This works as expected in case of UDP protocol: INVITE sip:2601@192.168.0.178:49162;transport=udp SIP/2.0 Record-Route: <sip:192.168.9.103;r2=on;lr;did=e2c.a191> Record-Route: <sip:10.28.80.1;r2=on;lr;did=e2c.a191> Via: SIP/2.0/UDP 192.168.9.103;branch=z9hG4bKcfa5.d64ecbd87d5315b5993c4ccf16f86537.0 Via: SIP/2.0/UDP 10.28.80.47:5060;rport=5060;branch=z9hG4bK3a9e9a4d But when the TCP protocol is used AND "listen" parameters are defined: listen=udp:10.28.80.1:5060 listen=tcp:10.28.80.1:5060 listen=udp:192.168.9.103:5060 listen=tcp:192.168.9.103:5060 then the outbound message looks like this: INVITE sip:2601@192.168.0.178:48758;transport=tcp SIP/2.0 Record-Route: <sip:10.28.80.1;transport=tcp;lr;did=bcd.72f> Via: SIP/2.0/TCP 10.28.80.1;branch=z9hG4bKb9ca.26ea08654c9dbc32bb0dc6e3b6f92d45.0;i=3 Via: SIP/2.0/TCP 10.28.80.47:5060;rport=33976;branch=z9hG4bK5291fab1 There are two problems there: a) only one Record-Route with leg "A" is inserted b) the added "Via" header field contains the leg "A" IP address instead of expected leg "B" IP address (192.168.9.103). In the LAN trace, I see that in reality the message was sent from leg "B". IMPORTANT: The problem occurs only when the "listen" parameters are defined in the Kamailio configuration. When the "listens" are not configured then everything works correctly. ### Troubleshooting #### Reproduction #### Debugging Data #### Log Messages http://updates.xorcom.com/~xorcom/kam-tcp-problem.tar.gz The archive contains the following files: * syslog-bad.log and bad.cap - Kamailio log and tcpdump trace of a call when the problem occurs * syslog-good.log and good.cap - Kamailio log and tcpdump trace of a call when the problem doesn't occur #### SIP Traffic ### Possible Solutions ### Additional Information kamailio -v version: kamailio 5.2.3 (x86_64/linux) 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: unknown compiled with gcc 7.3.0 ***Operating System**: Ubuntu 18.0.4 -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] import_file - wildcard support (#2125)

by sergey-safarov

### Description Could you extend `import_file` directive to support wildcards like ``` import_file "/run/kamailio/cfg/*" ``` This will allow place runtime config files with public IP of VM. Useful for cloud installation. ``` listen=udp:eth0 advertise 52.24.72.57:5060 listen=tcp:eth0 advertise 52.24.72.57:5060 ``` ### Expected behavior All files matched to wildcard included into config #### Actual observed behavior wildcard ignored -- You are receiving this because you are subscribed to this thread.

[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] 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] topos module seems to break re-SUBSCRIBE routing to downstream destinations (#1724)

by George Diamantopoulos

### Description Kamailio seems to fail to properly route in-dialog SUBSCRIBE with the topos module enabled. In this configuration, SUBSCRIBEs are expected to be delivered to a downstream UAS, an asterisk instance in the internal network. record_route() is executed for all initial requests, including SUBSCRIBEs. Routing is performed correctly with the topos module disabled, no other modifications were needed.  ### Troubleshooting I haven't been able to work around this issue in any other way other than disabling the topos module. #### Reproduction The configuration used is a heavily modified version of the example configuration file, but the handling of SUBSCRIBEs is generally simple. The initial SUBSCRIBE is subject to some tests, the R-URI is edited and dispatched to a farm of asterisk servers based on some criteria. Record Routing is enforced, so subsequent in-dialog re-SUBSCRIBEs are expected to be routed with loose_route(), which doesn't seem to handle things properly.  #### Debugging Data I'm attaching kamailio logs with debug=4, cfg_trace  #### Log Messages See attachments  #### SIP Traffic Please see: https://www.cloudshark.org/captures/d2643aae7f2a  ### Possible Solutions Using topoh instead for topos, but unfortunately this will break communication for other reasons (messages too large/UDP fragmentation for some peers). ### Additional Information * **Kamailio Version** Tried with kamailio 5.1.6 and kamailio 5.3.0-dev0 deb.kamailio.org repositories were used to acquire binaries for both versions * **Operating System**: Debian Stretch  [resubscribe.log](https://github.com/kamailio/kamailio/files/2586440/resubsc… -- You are receiving this because you are subscribed to this thread.

[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.
