Kamailio variable -> Kamailio script.

by Luis Martin Gil

Hi, I'm trying to pass a variable back to the Kamailio script from the Kamailio module. Let's say that my module is called "random" and it exports the function: static int do_this(struct sip_msg *msg, char* _information); - I pass some "_param1" and "_param2" parameters to this function from Kamailio script: (Kamailio script code) loadmodule "random.so" modparam("random", "_param1", "www.host.com") modparam("random", "_param2", 8877) - "_information" is the content I get back from the function. Reading _param1 and _param2 from the function of the module is pretty straight forward. In order to write the "_information" variable and being able to read from Kamailio script : (Module code) // this is inside do_this() function // "content" has the value of the information that I would like to pass back from the function. pv_spec_t* dst; pv_value_t val; val.rs.s = content; val.rs.len = strlen(content); val.flags = PV_VAL_STR; dst = (pv_spec_t *) _information; dst->setf(msg, &dst->pvp, (int)EQ_T, &val); >From Kamailio script I can do: (Kamailio script code) xlog("L_INFO","Calling do_this()\n"); $var(result) = do_this("$var(response)"); xlog("L_INFO","Returning do_this(). result=$var(result). uri=$var(response)\n"); And works fine. Now, I was wondering If I can have the _information parameter as this : (Kamailio script code) loadmodule "random.so" modparam("random", "_param1", "www.host.com") modparam("random", "_param2", 8877) modparam("random", "_information", $(response)) Changing the interface of the function as: static int do_this(struct sip_msg *msg); Calling from the kamailio script as this: (Kamailio script code) xlog("L_INFO","Calling do_this()\n"); $var(result) = do_this(); xlog("L_INFO","Returning do_this(). result=$var(result). uri=$var(response)\n"); But it doesn't work. Anyone is welcome to provide insight. Thanks, Luis

SIP identity - AUTH_identity

by Olle E. Johansson

Hello! Today at SIPit 29 we successfully tested the kamailio auth_identity module that implements RFC 4474. We could successfully add SIP identity headers and verify incoming headers from one other implementation. Now, the module is not built for scalability and redundance. A lot of stuff is cached in RAM, like certificates - which could lead to an DOS attack vector. It doesn't make it simple either when you have multiple servers for one domain. Maybe a memcached backend could help. We will also try to look for other attack vectors, like sending bad HTTPS URL's. Regardless, this was the first time I got SIP identity working and the others are struggling with their code to get their end working :-) Kamailio rocks. /O
