Hi all,
due to malformed INVITEs I'm receiving from clients I like to use sanity
module. But after few test I'm affraid I don't understand correctly how
it works :-)
1. I try to load the module:
loadmodule "sanity.so"
modparam("sanity", "default_checks", "999")
and kamailio rejects config with the:
ERROR:core:set_mod_param_regex: parameter <default_checks> not found in
module <sanity>
2. When I comment out "modparam", kamailio starts successfuly, but:
All INVITEs (from all clients) are reject through this snippet of code
if (method=="INVITE") {
if (sanity_check("128")) {
xlog("L_ERR", "bad INVITE SDP body length from $si:$sp\n");
exit;
} else if (sanity_check("1024", "7")) {
xlog("L_ERR", "malformed INVITE from $si:$sp\n");
exit;
}
}
I don't think that all of them could have bad length on SDP body (about
120 diffenet UAC types), so I assume I use "sanity" wrong way...
Could you, please, shed some light to proper usage of sanity module?
Thank you very much!
Best regards,

Hi kokoska,
the default_checks parameter is a INT, not a string. Remove the quotes from
the number. The module documentation is wrong, i'll fix this.

Hi kokoska,
you should get a exact error message in the reply, which indicates the check
that failed. The parameter in the sanity_check is the sum of all checks, so
this includes also a bit more checks, take a look in the documentation.

Yes, but I could "rearm" the checks only i deep night - due to load :-)
I will look at it.

I know that parameter is sum of all checks, but I think - based on the
docs - that if I explicitly specify what test I want ("128"), only the
selected test is done. Am I wrong?
Or, may be, should I use integer insted of string (and thus docs are a
little bit missleading)?
Thank you once more for your time, Henning!

According to the docs and the code, it should work the same way as the module
parameter. But the example shows it a bit different.. You need to use quotes
in the function, it don't work without it.

If I catch it properly, the conclusion is: If I want only Content-Legth
check for INVITEs, I should use:
if (method=="INVITE") {
if (sanity_check("128")) {
...
This is exactly what I have done :-) I will try it once more at about
midnight and let you know how it works...
Thank you for your help!
