[kamailio/kamailio] pv needed to get access to X509v3 Subject Alternative Names of peer's SSL certificate (#707)
by juha-h 11 Jan '22

11 Jan '22

A sip proxy may serve many domains listed in its SSL certificate X509v3 Subject Alternative Name field. In order to find out if a peer sip proxy is serving a particular domain, access would be needed in config file to this list of domains. --- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] TLS module: access UID attribute (#1843)
by Sebastian Denz 24 Nov '21

24 Nov '21

### Description While implementing an edgeproxy based on kamailio i have to add a custom SIPHeader which contains the uid from the useragents client certificate. The UID is part of the subject like: O = Company CN = Sebastian Denz UID = denz But i cant access that attribute. All i can do is reading the CN and O. ### Expected behavior There should be a select to access the uid Attribute from the subject, or at least a select which returns the whole subject, so it can be parsed manually in kamailio.cfg. #### Actual observed behavior It is only possible to access the O and CN field from the subject. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` kamailio -v version: kamailio 5.2.0 (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 5.3.1 ``` -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] topos module producing invalid SIP message (missing Via header) when handling 200 OK to OPTIONS request (#1350)
by George Diamantopoulos 20 Oct '21

20 Oct '21

Hello all, I've come across the following issue with topos on Kamailio 5.1.0-rc2. ### Description Kamailio acts as a proxy for asterisk instances residing in a private IP range. Asterisk's peers are configured with their public IP address or hostname, but asterisk will dispatch requests to them to kamailio instead (because kamailio's IP is set in outboundproxy option in peer definition). This works fine for INVITEs, but if qualify=yes is set for the peer, asterisk will send out OPTIONs to monitor these peers. If the topos module is loaded, 200 OK replies to these OPTIONs will be malformed when forwarded from kamailio to asterisk (no Via header present). Disabling the topos module will resolve this. ### Troubleshooting #### Reproduction Configure a peer in asterisk with outboundproxy option set to kamailio's IP address. Set qualify=yes. Adjust kamailio's default configuration so that OPTIONs to other hosts besides itself are routed. Change the following section in request_route: ``` if ($rU==$null) { # request with no Username in RURI sl_send_reply("484","Address Incomplete"); exit; } ``` to: ``` if ( ($rU==$null) && !(is_method("OPTIONS")) ) { # request with no Username in RURI sl_send_reply("484","Address Incomplete"); exit; } # Permit asterisk's monitoring using options if(is_method("OPTIONS") && uri!=myself) { route(RELAY); } ``` Enable and configure the topos module with database. #### SIP Traffic asterisk:5060 -> kamailio:5060 ``` OPTIONS sip:peer.domain.tld SIP/2.0 Via: SIP/2.0/UDP asterisk:5060;branch=z9hG4bK460330cf;rport Max-Forwards: 70 From: "asterisk" <sip:asterisk@domain.tld>;tag=as690c2406 To: <sip:peer.domain.tld> Contact: <sip:asterisk@asterisk:5060> Call-ID: 6548f43b2d8740122186bb0c6e72ac78(a)domain.tld CSeq: 102 OPTIONS User-Agent: myUA Date: Sun, 03 Dec 2017 00:39:38 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer Content-Length: 0 ``` kamailio:5060 -> peer:5060 ``` OPTIONS sip:peer.domain.tld SIP/2.0 Via: SIP/2.0/UDP kamailio:5060;branch=z9hG4bK460330cf;rport Max-Forwards: 69 From: "asterisk" <sip:asterisk@domain.tld>;tag=as690c2406 To: <sip:peer.domain.tld> Contact: <sip:asterisk@asterisk:5060> Call-ID: 6548f43b2d8740122186bb0c6e72ac78(a)domain.tld CSeq: 102 OPTIONS User-Agent: myUA Date: Sun, 03 Dec 2017 00:39:38 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer Content-Length: 0 ``` peer:5060 -> kamailio:5060 ``` SIP/2.0 200 OK Via: SIP/2.0/UDP kamailio;branch=z9hG4bKda8d.cc03bd2def8ad36e8c43f61ab31a636f.0;received=kamailio;rport=5060 From: "asterisk" <sip:asterisk@domain.tld>;tag=as690c2406 To: <sip:peer.domain.tld>;tag=as472874ee Call-ID: 6548f43b2d8740122186bb0c6e72ac78(a)domain.tld CSeq: 102 OPTIONS Server: myUA Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer Contact: <sip:peer:5060> Accept: application/sdp Content-Length: 0 ``` **kamailio:5060 -> asterisk:5060: Missing Via Header** ``` SIP/2.0 200 OK From: "asterisk" <sip:asterisk@domain.tld>;tag=as690c2406 To: <sip:peer.domain.tld>;tag=as472874ee Call-ID: 6548f43b2d8740122186bb0c6e72ac78(a)domain.tld CSeq: 102 OPTIONS Server: myUA Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer Contact: <sip:peer:5060> Accept: application/sdp Content-Length: 0 ``` ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.1.0-rc2 (x86_64/linux) flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, 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_LISTEN 16, 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 6.3.0 ``` * **Operating System**: ``` Debian 9.1 ``` * **Other pertinent configuration information**: This kamailio box has several network interfaces. mhomed is not used, instead force_send_socket is called where necessary.

[kamailio/kamailio] mod kazoo: wrong kazoo_publish example (#2627)
by sergey-safarov 21 Sep '21

21 Sep '21

### Description Example 1.21. kazoo_publish usage contains string ``` $var(amqp_payload_request) = "{'Event-Category' : 'directory', 'Event-Name' : 'reg_success', 'Contact' : '" + $var(fs_contact) + "', 'Call-ID' : '" + $ci + "', 'Realm' : '" + $fd +"', 'Username' : '" + $fU + "', 'From-User' : '" + $fU + "', 'From-Host' : '" + $fd + "', 'To-User' : '" + $tU +"', 'To-Host' : '" + $td + "', 'User-Agent' : '" + $ua +"' ," + $var(register_contants)+ " }"; ``` This example did not work because the string generates broken JSON: 1. here present value ` $var(register_contants)` but key is not present 2. JSON key and value must be started and terminated by `"` symbol (not by `'`) -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] db_redis: add support for native redis cluster (#1997)
by George Diamantopoulos 15 Sep '21

15 Sep '21

The db_redis module seems to only support connecting with a single redis instance. It is not evident from the documentation if it implements support for native redis cluster by honouring 'MOVED' replies. ndb_redis seems to have support for native redis clusters, and supports both automatic (see allow_dynamic_nodes parameter of ndb_redis) and manual configuration of redis nodes. Since both modules are based on the hiredis library, is it safe to assume this support could be easily implemented, with some code sharing between the two modules perhaps? If db_redis supports clusters with automatic configuration only (by processing MOVED replies), perhaps the module's documentation should be updated to reflect that. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] lost: dynamic HELD url resolving (#2574)
by sergey-safarov 07 May '21

07 May '21

### Description According to design logic HELD request need to send a carrier LIS server. Now lost module sends this request to the preconfigured server via `http_client/httpcon` param. I prefer to use dynamic LIS server discovery according to [rfc7216#section-4](https://tools.ietf.org/html/rfc7216#section-4) and [rfc5986#section-4](https://tools.ietf.org/html/rfc5986#section-4). So dynamic LIS discovery works as: 1. Kamailio send reverse `.in-addr.arpa.` or `.ip6.arpa.` DNS request and caller host DNS name; 2. Kamailio send `LIS:HELD` NAPTR request for a resolved caller hostname and LIS server. 3. Kamailio send HELD request for resolved LIS address. So do get working dynamic LIS discovery required to implement two DNS requests. If any DNS request will fail, then `lost_held_query` function returns an error code. To define required dynamic LIS discovery I suggest use an empty string ("") or NULL value ($null) as the first ("con") function param. This feature request for discussion with lost module author (Wolfgang Kampichler @wkampich) and other interest devs. The ticket may be closed at any time. -- You are receiving this because you are subscribed to this thread.

[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.
