Hi Ben,



the $? Is not deprecated. Its probably just not documented in the PV page, should be added there.



Cheers,



Henning

After looking through the rest of the secfilter documentation, the examples for all other functions it exports evaluate against $? rather than $avp(secfilter),  so it seems very likely the documentation is in error.



As a side observation is $? deprecated?  It's not listed at all in the pseudovariable documentation, and has only one mention in the core documentation.

Not really an answer here, but more of a question:  How is this supposed to work? Why would $avp(secfilter) be set at all?  I know that this is basically the example from the secfilter documentation:



if (geoip2_match("$si", "src")) {

    secf_check_country($gip2(src=>cc));

    if ($avp(secfilter) == -2) {

        xlog("L_ALERT", "$rm from $si blocked because Country '$gip2(src=>cc)' is blacklisted");

        exit;

    }

}



Is $avp(secfilter) automatically reserved by the module?  If so, it doesn't appear to be documented.  I would try checking it against $rc, or better yet, assigning the return of secf_check_country() to a variable:



$avp(secf_cc_rc) = secf_check_country($gip2(src=>cc));

if ( $avp(secf_cc_rc) == -2 ) {

    ## code here

}





Finally, it looks odd that the argument to secf_check_country() isn't quoted, but maybe that's just my early morning eyes.



Regards,

Kaufman

Good morning everyone,



Im trying to configure secfilter module to harden our kamailio.

After configuring geoip2 module and checking that using function geoip2_match("$si", "src") it shows the country properly. I’ve configured secfilter module, and I think it’s also working because kamailio service starts and with kamcmd secfilter.print I can see the entries from the DDBB.

But when I call the function secf_check_country($gip2(src=>cc)) it always replies with <null> (I saw it in this variable $avp(secfilter)). I’ve also tried to use $? Variable and it shows “1”, in the module documentation I saw that 1 means “the value is not found”. But when I use kamcmd secfilter.print I can see the country in the output and it’s spelled exactly the same that in $gip2(src=>cc)



I don’t know if there’s something I’m missing. Any help would be appreciated.

Thanks in advance



This is the code I’m executing

if (geoip2_match("$si", "src")) {

                secf_check_country($gip2(src=>cc));

                xlog("L_ALERT", "La respuesta de de secfilter es $avp(secfilter)");

                xlog("L_ALERT", "$?");

                if ($avp(secfilter) == 2) {

                        return;

                }

        xlog("L_ALERT", "$rm from $si blocked because Country '$gip2(src=>cc)' is blacklisted");

        exit;

        }

And this is what appears in the logs
