[kamailio/kamailio] DNS destination resolution failure when too many SRV records (#2651)
by jklingenmeyer 03 May '21

03 May '21

### Description DNS core resolver fails in returning a valid IP when there are too many SRV results in the DNS reply. It acts like if no records were found, so request is not relayed and a 478 reply is generated instead (in the example of a DNS name in $ru or $du). ### Troubleshooting #### Reproduction It is easy to reproduce with DNS failover + NAPTR enabled (cf parameters used far below) and with such DNS records: ``` # dig +short NAPTR ko.sip.provider.com 50 30 "S" "SIP+D2U" "" _sip._udp.ko.sip.provider.com. # dig +short SRV _sip._udp.ko.sip.provider.com. 10 10 5060 endpoint-01.k0.sip.provider.com. 10 10 5060 endpoint-02.k0.sip.provider.com. 10 10 5060 endpoint-03.k0.sip.provider.com. 10 10 5060 endpoint-04.k0.sip.provider.com. 10 10 5060 endpoint-05.k0.sip.provider.com. 10 10 5060 endpoint-06.k0.sip.provider.com. 10 10 5060 endpoint-07.k0.sip.provider.com. 10 10 5060 endpoint-08.k0.sip.provider.com. 10 10 5060 endpoint-09.k0.sip.provider.com. # Each SRV result above has a corresponding # 'A' record so that command below gives a correct IP: # dig +short A endpoint-01.k0.sip.provider.com. ``` To reproduce, relay a request towards it, like: `$du="sip:ko.sip.provider.com"` #### Debugging data One interesting thing is that Kamailio behaves exactly the same as the `sip-dig` tool. But `sip-dig` seems to be limited on the DNS reply size it can handle (cf my comment below about the RFC). Does Kamailio have this same kind of limitation regarding DNS resolution? #### Log Messages ##### Failure example: with 9 SRV records ``` DEBUG: <core> [core/dns_cache.c:527]: _dns_hash_find():

There are some max defined in `dns_cache.c` but I did not found a relation between them and my issue. Could there be a limitation in result size? Here is what I got from my RFCs reading regarding that: * Extract from **RFC 2782 DNS RR** (mentioned in RFC 3263 as being the RFC to follow for implementing DNS in SIP): > Currently there's a practical limit of 512 bytes for DNS replies. > Until all resolvers can handle larger responses, domain administrators are strongly advised to keep their SRV replies below 512 bytes. There is a RFC about how to deal with truncated messages: > If a truncated response comes back from an SRV query, the rules described in RFC 2181 (https://tools.ietf.org/html/rfc2181#page-11) shall apply. ### Additional Information * **Kamailio Version** - kamailio 5.3.8 ``` dns_try_naptr=yes dns_tcp_pref = 1 dns_udp_pref = 1 dns_tls_pref = 1 dns_srv_lb=yes use_dns_failover=yes use_dns_cache=yes dns_cache_max_ttl=30 ``` * **Operating System**: Debian 9.13 on Docker Thanks -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Wrong Record-Route and Via header fields when TCP is used (#2033)
by leonid-xorcom 03 May '21

03 May '21

### 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.

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 05 Apr '21

05 Apr '21

### 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 01 Apr '21

01 Apr '21

### 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] import_file - wildcard support (#2125)
by sergey-safarov 31 Mar '21

31 Mar '21

### 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] $(hdr(foo)[idx]) is 0-based, textopsx.remove_hf_value("foo[idx]") is 1-based, they should be the same (#2387)
by Sebastian Damm 31 Mar '21

31 Mar '21

### 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 31 Mar '21

31 Mar '21

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.
