[kamailio/kamailio] lost: resolve geolocation url using POST (#2641)
by sergey-safarov 03 May '21

03 May '21

### Description According [RFC5985](https://tools.ietf.org/html/rfc5985) > The POST method is the only method REQUIRED for HELD. If a LIS chooses to support GET or HEAD, it SHOULD consider the kind of application doing the GET. So not all LIS servers support the GET method and only the POST method always present. Also [rfc6753#section-3.2](https://tools.ietf.org/html/rfc6753#section-3.2) > An HTTP GET request to a HELD URI produces a HELD response as if the following HELD request had been sent using HTTP POST: <locationRequest xmlns="urn:ietf:params:xml:ns:geopriv:held"> <locationType exact="false"> geodetic civic </locationType> </locationRequest> ### Expected behavior Dereference Geolocation URLs using POST method with content according [rfc6753#section-3.2](https://tools.ietf.org/html/rfc6753#section-3.2) -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] [Feature] RFC 8898 support (#2669)
by Grzegorz Kapkowski 03 May '21

03 May '21

### Description Hi, is there anyone working on adding support for [RFC 8898](https://tools.ietf.org/html/rfc8898) and do you know of any clients that already implement it or are working towards supporting it? How could I go about starting such effort? ### RFC 8898 Third-Party Token-Based Authentication and Authorization for Session Initiation Protocol (SIP) Abstract This document defines the "Bearer" authentication scheme for the Session Initiation Protocol (SIP) and a mechanism by which user authentication and SIP registration authorization is delegated to a third party, using the OAuth 2.0 framework and OpenID Connect Core 1.0. This document updates RFC 3261 to provide guidance on how a SIP User Agent Client (UAC) responds to a SIP 401/407 response that contains multiple WWW-Authenticate/Proxy-Authenticate header fields. ... -- You are receiving this because you are subscribed to this thread.

[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.
