Hi, AFAIK SR doesn't provide a way to binary compare two IPv6 (correct me if I'm wrong). About IPv4 comparison, I assume it's compared as a string: if ($rd == "1.2.3.4") so it works. But in case of IPv6 it would not work as the same IPv6 could take different (but equivalent) representations: "1080:0000:0000:0000:0008:0800:200C:417A" "1080:0:0:0:8:800:200C:417A" "1080::8:800:200C:417A" I'd like to add a function to perform IPv6 binary comparison (as I've already coded it in a personal project), could you please tell me in which module should it take place? I mean something as: -------------------------------------------------------------------------- compare_ips(ip1, ip2) Returns 1 if both IP's are two equal IPv4 or two equal IPv6. Returns -1 if both IP's are valid but not equal. Returns -2 if at least one give IP is not a valid IPv4 or IPv6. Parameters: - ip1: An string of pv containing a IPv4 or IPv6 in text representation. - ip2: An string of pv containing a IPv4 or IPv6 in text representation. -------------------------------------------------------------------------- Thanks. -- Iñaki Baz Castillo <ibc(a)aliax.net>

Problem with switch() when evaluating a function rather than $rc

by Iñaki Baz Castillo

Hi, I've coded a function that returns 1, 2, 3 or -1. It does it correctly, however when evaluating the result of such function in a switch() it fails: switch(my_function("lalala")) { case 1: [...] The way it works is: my_function("lalala"); switch(my_function($rc)) { case 1: [...] Is it the expected behavior? -- Iñaki Baz Castillo <ibc(a)aliax.net>

git:master: module_k/ pv Changed the nameaddr transformation by relaxing the requirements on the input .

by Marius Zbihlei

Module: sip-router Branch: master Commit: 9287609db4ac64c709aa500e6326ac33af2c2061 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=9287609… Author: Marius Zbihlei <marius.zbihlei(a)1and1.ro> Committer: Marius Zbihlei <marius.zbihlei(a)1and1.ro> Date: Thu Apr 28 10:30:55 2011 +0300 module_k/pv Changed the nameaddr transformation by relaxing the requirements on the input. As some headers might be either uri or nameaddr form, using a single transformation for parsing them was impossible, as nameaddr.uri returns "" on an uri input(e.g. sip:12345@example.com). With this change, the nameaddr transformation succedes and the resulting transformation places the whole string in the .uri field, .name field being empty. A transformation chaning like the one below will work as expected on both SIP URIs and SIP Nameaddr $(val(test){nameaddr.uri}{uri.domain}) --- modules_k/pv/pv_trans.c | 11 +++++++++-- 1 files changed, 9 insertions(+), 2 deletions(-) diff --git a/modules_k/pv/pv_trans.c b/modules_k/pv/pv_trans.c index b60f529..4cf2555 100644 --- a/modules_k/pv/pv_trans.c +++ b/modules_k/pv/pv_trans.c @@ -1016,6 +1016,7 @@ int tr_eval_nameaddr(struct sip_msg *msg, tr_param_t *tp, int subtype, pv_value_t *val) { str sv; + int ret; if(val==NULL || (!(val->flags&PV_VAL_STR)) || val->rs.len<=0) return -1; @@ -1045,8 +1046,14 @@ int tr_eval_nameaddr(struct sip_msg *msg, tr_param_t *tp, int subtype, /* parse params */ sv = _tr_nameaddr_str; - if (parse_nameaddr(&sv, &_tr_nameaddr)<0) - return -1; + ret = parse_nameaddr(&sv, &_tr_nameaddr); + if (ret < 0) { + if(ret != -3) return -1; + /* -3 means no "<" found so treat whole nameaddr as an URI */ + _tr_nameaddr.uri = _tr_nameaddr_str; + _tr_nameaddr.name = _tr_empty; + _tr_nameaddr.len = _tr_nameaddr_str.len; + } } memset(val, 0, sizeof(pv_value_t));

ORACLE_DB module Problem

Hi all, we are trying to setup a Kamailio as a SIP/SIMPLE presence server for chat based on the guide published in SIP SIMPLE Presence Made Simple with Kamailio 3.1.x on the site: http://kb.asipto.com/kamailio:presence:k31-made-simple. *The OS we are using is Linux RHEL 5.6 x64 and ORACLE 11g as Database*.

Error parsing Via parameter with space before semicolon

by Iñaki Baz Castillo

Hi, the following Via causes a parsing error in sip-router: Via: SIP/2.0/UDP 1.2.3.4;branch=z9hG4bK1aaaaa;rport;param1 ;param2<CRLF> It occurs due to the space before ";param2". If param2 has value (param2=abc or param2 = abc) the error also occurs. According to RFC 3261 BNF the above Via is 100% valid as header parameters separator is SEMI which is defined as: SEMI = SWS ";" SWS SWS = [LWS] LWS = [*WSP CRLF] 1*WSP WSP = SP | HTAB; -- Iñaki Baz Castillo <ibc(a)aliax.net>

RLS bug fixes

by Peter Dunkley

Hello, Please find attached a patch containing three small RLS bug fixes: 1) A string comparison that fails because sometimes one of the strings is '\0' terminated and the other never is. 2) A fix for when some non-RLS SUBSCRIBEs are not identified as such. 3) A fix for a small typo in an error diagnostic.
