[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.

xflag losing state on serial forking

by David Escartin

Dear all i think i have noticed a wrong behaviour with xflags. When they are set in a failure_route and a t_relay is done after that to a destination, its state is lost in the next on_reply route. This doesn't happen with regular transaction flags, and it doesn't happen with xflags either when xflag is set inside an onreply_route. We have seen it on versions 5.3 and 5.4 Could you please confirm this? thanks a lot regards david escartin -- [image: Logo] David Escartín Almudévar VoIP/Switch Engineer descartin(a)sonoc.io *SONOC* C/ Josefa Amar y Borbón, 10, 4ª · 50001 Zaragoza, España Tlf: +34 917019888 · www.sonoc.io

[kamailio/kamailio] Add display name support to "pua_dialoginfo" (#2615)

by Jake Greene

### Description It doesn't look like the "pua_dialoginfo" module has support for the "display" attribute in the identity tag. This tag is used by some phones to update the phone display with caller/callee information for the respective key. I'm wondering how difficult it would be to add this feature. Thanks in advance for anyone who reads this! ### Expected behavior Kamailio includes display attribute in identity tags in generated publish messages. <pre> <dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="1" state="full"> <dialog id="as7d900as8" call-id="a84b4c76e66710" local-tag="1928301774" remote-tag="456887766" direction="initiator"> <state>early</state> <local> <identity display="Alice">sip:alice@example.com</identity> <target uri="sip:alice@phone11.example.com"/> </local> <remote> <identity display="Bob">sip:bob@example.org</identity> <target uri="sip:bobster@phone21.example.org"/> </remote> </dialog> </dialog-info> </pre> #### Actual observed behavior Kamailio generates a publish request for dialog events similar to the one below. The display attribute is not included in the "identity" tags. This means that when a notify message is sent to a watcher for this publish, the name is not rendered on the phone display. <pre> <dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="1" state="full"> <dialog id="as7d900as8" call-id="a84b4c76e66710" local-tag="1928301774" remote-tag="456887766" direction="initiator"> <state>early</state> <local> <identity>sip:alice@example.com</identity> <target uri="sip:alice@phone11.example.com"/> </local> <remote> <identity>sip:bob@example.org</identity> <target uri="sip:bobster@phone21.example.org"/> </remote> </dialog> </dialog-info> </pre> ### Possible Solutions I added a small modification to the module as a POC and it works as expected. With the following modification, the phone display is updated with the string in the “display” attribute. I added line 191-193 below, between lines 190 & 191 on the current master branch. The example below shows the “remote” tag, I also did the same thing for the local tag a few more lines down. <pre> 184 tag_node = xmlNewChild(remote_node, NULL, BAD_CAST "identity", 185 BAD_CAST buf) ; 186 if( tag_node ==NULL) 187 { 188 LM_ERR("while adding childn"); 189 goto error; 190 } 191 /* Testing - adding display attribute to the identity tag */ 192 xmlNewProp(tag_node, BAD_CAST "display", BAD_CAST "RemoteCallerName"); 193 /* */ 195 196 tag_node = xmlNewChild(remote_node, NULL, BAD_CAST "target", NULL); 197 if( tag_node ==NULL) </pre> Here is a link to the file in the module I’m referring to: https://github.com/kamailio/kamailio/blob/master/src/modules/pua_dialoginfo… I don’t really have any professional experience writing C code, and I was unable to identify a way to grab this string from the “From” header. Unfortunately, because I would have really loved to give this feature back to the community! ### Additional Information Thank you so much for this amazing software. I absolutely adore Kamailio! If someone is interested in this, please let me know if there is anything I can do to help. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Kamailio 5.0.4 extremely slow carrierroute preloading (#2653)

by NiteCrwlr

### Description Carrierroute module takes now 16 minutes to load about 50'000 entries from postgres-db. In version 5.0.3 it was 10 seconds from the same db. ### Troubleshooting #### Reproduction Install kamailio 5.0.3 and fill your carrierroute table with thousands of entries. See how fast its loaded. Then install 5.0.4 and see how long it takes now. You can observe the query "SELECT * FROM carrierroute WHERE carrier=1 and domain=1 and prob>0" multiple times in the postgres-db log. #### Debugging Data none. #### Log Messages not needed. #### SIP Traffic not needed. ### Possible Solutions Perhaps try to do the check "in-memory" instead generate a new sql-query. ### Additional Information This bug exists in Kamilio versions >=5.0.4 and is (potentially) introduced by: commit 9800aba65146b72623bb512049300d1beb8c8ec4 Author: Huseyin Dikme <hueseyin.dikme(a)1und1.de> Date: Tue Sep 12 15:37:17 2017 +0200 carrierroute: warning for the same carrier/domain having routes with only 0 probability - While starting kamailio or reloading the routes, if the same carrier/domain pairs do not have any route with a probability other than 0 (zero) then an error log will be printed on the screen. Besides, the log "invalid dice_max value" in the cr_func.c has been made more clear.

[kamailio/kamailio] $(hdr(foo)[idx]) is 0-based, textopsx.remove_hf_value("foo[idx]") is 1-based, they should be the same (#2387)

by Sebastian Damm

### Description We have some JS code looping over all P-Asserted-Identity headers removing some of the entries: ``` let headerIndex = 0; const telUriMatcher = new RegExp("tel:"); let paiValue = ksr.pv .gete("$(hdr(P-Asserted-Identity)[" + headerIndex + "])") .toString(); while (paiValue.length > 0) { ksr.info( `${ksr.pv.getw("$ci")}: Found P-A-I header with content <${ksr.pv.getw( "$(hdr(P-Asserted-Identity)[" + headerIndex + "])" )}> at index ${headerIndex}\n` ); if (telUriMatcher.test(paiValue)) { ksr.info( `${ksr.pv.getw("$ci")}: Removed P-A-I header ${ksr.pv.getw( "$(hdr(P-Asserted-Identity)[" + headerIndex + "])" )}\n` ); ksr.textopsx.remove_hf_value( "P-Asserted-Identity[" + headerIndex + "]" ); } headerIndex++; paiValue = ksr.pv .gete("$(hdr(P-Asserted-Identity)[" + headerIndex + "])") .toString(); } ``` In our tests, we wanted to remove the second header, but the first one got removed instead. The pseudovars docs say, the index of a header is 0-based. In textopsx docs it doesn't explicitly say, it's 1-based, but the first example shows it actually is. ### Possible Solutions Right now, we replaced the line ``` ksr.textopsx.remove_hf_value("P-Asserted-Identity[" + headerIndex + "]"); ``` with this one: ``` ksr.textopsx.remove_hf_value("P-Asserted-Identity[" + (headerIndex + 1) + "]"); ``` This solves the problem, but it is not what we would expect. Both header access methods should use the same index base. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.3.5 (x86_64/linux) 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_BLACKLIST, 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: unknown compiled with gcc 8.3.0 ``` * **Operating System**:  ``` Linux hostname 4.19.0-9-amd64 #1 SMP Debian 4.19.118-2+deb10u1 (2020-06-07) x86_64 GNU/Linux ``` -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Dispatcher SNI support (#2591)

by Tim Chubb

Is it possible to specify a specific server name/server id for dispatcher to use to send pings with (and in outgoing requests) It seems I can't (or haven't noticed in the docs) an event route I could use to set the xavp, as tm:local-request happens to late to use there. As an aside why isn't there a "last chance before send" event route? This is probably a feature request more than a bug, as the ideal solution from my point of view would be an additional dispatcher attrs value to be able to set it per destination in the underlying dispatcher data Judging by the output from tls module dbg the tls xavps are checked, before the ping is sent.. I've had a cursery glance at dispatch.c and it seems easy enough to add an extra attr parameter but I'm ata loss as to how I would preset the server name/id xavp... (I'm no c dev, but can Google quick enough to follow along mostly, and happy to fiddle away if anyone can be kind enough to give me some pointers in the right direction) -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] xavp set in event_route[tm:local-request] are not used in SIP transaction (#2413)

by arkadiam

### Description I'm using dispatcher module like: ``` loadmodule "dispatcher.so" modparam("dispatcher", "list_file", "/etc/kamailio/dispatcher.list") modparam("dispatcher", "ds_probing_mode", 1) modparam("dispatcher", "ds_ping_interval", 60) ``` With records like: ``` 1 sip:sip.host.com;transport=tls 0 1 socket=tls:111.222.233.10:5061;ping_from=sip:my-domain-01.com 2 sip:sip.host.com;transport=tls 0 1 socket=tls:111.222.233.20:5061;ping_from=sip:my-domain-02.com ``` In event_route[tm:local-request] I'm modifying 'Contact' and would like to specify what client TLS profile to use via server name or server id. ``` event_route[tm:local-request] { if(is_method("OPTIONS")) { append_hf("Contact: <sip:some-host.com;transport=tls>\r\n"); $xavp(tls=>server_name)=$fd; $xavp(tls[0]=>server_id)=$fd; } } ``` Setting 'tls' xavp doesn't make any difference and default client TLS profile is being used. It happens because in src/modules/tm/uac.c there is a code: ``` t_run_local_req() ... tm_xdata_swap(new_cell, &backup_xd, 0); ... /* restore original environment */ tm_xdata_swap(new_cell, &backup_xd, 1); ``` which resets any xavp changes done in event_route[tm:local-request]. Expected behaviour: ability to use xavp in tm:local-request route. That would allow to choose TLS client profile for dispatcher initiated requests. ### Possible Solutions As a hack, in tm_xdata_swap() for mode=1, don't restore xavp list if it was NULL. ``` if (x->xavps_list != NULL && *x->xavps_list==NULL) { // .... don't restore empty list... } else { xavp_set_list(x->xavps_list); } ``` This change allows to select required TLS profile for dispatcher requests. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.3.5 (x86_64/linux) ff2f8c-dirty 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_BLACKLIST, 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: ff2f8c -dirty compiled on 10:19:05 Jul 28 2020 with gcc 7.5.0 ``` * **Operating System**: ``` Linux xx 4.15.0-111-generic #112-Ubuntu SMP Thu Jul 9 20:32:34 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux ``` -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] topos+topos_redis TTL for SUBSCRIBE (#2652)

by goharahmed

### Description topos_redis sets TTL on dialogs including presence SUBSCRIPTIONs. Once the TTL expires on those SUBSCRIBEs the topos module fails to route the in-dialog NOTIFYs & subsequent SUBSCRIBEs. That causes presence to break.  ### Troubleshooting ``` loadmodule "topos_redis.so" modparam("topos_redis", "serverid", "srv1") loadmodule "topos.so" modparam("topos", "storage", "redis") ``` #### Reproduction load up topos and topos_redis module, set expiration in topos_redis to 600 (just to reproduce this) create a dialog, either INVITE or SUBSCRIBE anything is fine. Once the TTL is expired the in-dialog routing of packets fail in route[WITHINDLG] with 404 Not here. The route[WITHINGDLG] is just the standard one for us(can be pasted when needed) I can set the TTL to few days, but doing that brought the problem back for SUBSCRIBEs since the desk phone stay alive for weeks at a stretch.  ### Possible Solutions I could only think about renewing/refreshing the TTL for dialogs whenever they're loaded, so I modified the topos and topos_redis module for this and tested it. so far it works well and SUBSCRIBEs/NOTIFYs have been getting routed perfectly fine over the course of a week+  ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.4.3 (x86_64/linux) a96451-dirty 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_BLACKLIST, 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: a96451 -dirty compiled on 23:44:16 Feb 20 2021 with gcc 8.3.0 ``` * **Operating System**:  ``` Debian GNU/Linux 10 (buster) Linux sbc-va-2 4.19.0-13-cloud-amd64 #1 SMP Debian 4.19.160-2 (2020-11-28) x86_64 GNU/Linux ``` * **Suggested Fix/Patch**: https://github.com/kamailio/kamailio/compare/master...goharahmed:master -- You are receiving this because you are subscribed to this thread.
