Hello,

I'm trying to use the userblacklist module to implement a global blacklist. I have a few questions about the module.

Is it possible to use a avp for the check_blacklist function? If i'm correct it will only parse the request URI, but i'm rewriting the URI in a branch route to allow different formats to different destinations. Or is this only possible with the check_user_blacklist function?

I also have a issue with numbers in E164 format with a leading +. I tried to escape this with a \ in the database but it will not load the entry's when i use the + in front of the number. Is the + supported by this module or should i strip it before the function and add it again afterwards?

Thanks,

Jan

The spec is null, so the crash is obvious. I have to look at the code to see why it expect to be a spec there, while it can be a static string.

Daniel,

Seems like it is not working anymore, i now have configured:

if (!check_user_blacklist("blacklist", "oranjelaan.net", "318001234")) { xlog("L_ALERT", "ALERT: $rU is blacklisted, rejecting call - IP=$si PORT=$sp R=$ru ID=$ci FU=$fu M=$rm UA=$ua\n"); sl_send_reply("403", "Blacklisted"); exit; }

With the following in db:

+----+-----------+----------------+-----------+-----------+ | id | username | domain | prefix | whitelist | +----+-----------+----------------+-----------+-----------+ | 3 | blacklist | oranjelaan.net | 318001234 | 0 | +----+-----------+----------------+-----------+-----------+

But is is not rejecting the call. If i use the fifo command all is fine:

[root@sip03 kamailio]# /usr/local/sbin/kamctl fifo check_userblacklist blacklist oranjelaan.net 318001234 318001234:: blacklisted=true

[root@sip03 kamailio]# /usr/local/sbin/kamctl fifo check_userblacklist blacklist oranjelaan.net 318001235 318001235:: blacklisted=false

Daniel,

Sorry was still some testing code, but without the ! it rejects everything.

Code:

xlog("L_NOTICE", "NOTICE: Chekking blacklist for number $(avp(ruri_number){s.substr,1,0}) with domain $avp(from_domain) - R=$ru ID=$ci FU=$fu M=$rm UA=$ua\n");

if (check_user_blacklist("blacklist", "$avp(from_domain)", "$(avp(ruri_number){s.substr,1,0})")) { xlog("L_ALERT", "ALERT: $(avp(ruri_number){s.substr,1,0}) with domain $avp(from_domain) is blacklisted, rejecting call - R=$ru ID=$ci FU=$fu M=$rm UA=$ua\n"); sl_send_reply("403", "Blacklisted"); exit; }

In the db: +----+-----------+----------------+-----------+-----------+ | id | username | domain | prefix | whitelist | +----+-----------+----------------+-----------+-----------+ | 3 | blacklist | oranjelaan.net | 318001234 | 0 | +----+-----------+----------------+-----------+-----------+

You have a negation of the function int the if expression, respectively: !check_user_blacklist(...)

If the function returns true on record match and you want to reject in that case, then just remove the ! in the expression.

Cheers, Daniel

Daniel,

Seems like it is not working anymore, i now have configured:

    if (!check_user_blacklist("blacklist", "oranjelaan.net",

"318001234")) { xlog("L_ALERT", "ALERT: $rU is blacklisted, rejecting call - IP=$si PORT=$sp R=$ru ID=$ci FU=$fu M=$rm UA=$ua\n"); sl_send_reply("403", "Blacklisted"); exit; }

With the following in db:

+----+-----------+----------------+-----------+-----------+ | id | username | domain | prefix | whitelist | +----+-----------+----------------+-----------+-----------+ | 3 | blacklist | oranjelaan.net | 318001234 | 0 | +----+-----------+----------------+-----------+-----------+

But is is not rejecting the call. If i use the fifo command all is fine:

[root@sip03 kamailio]# /usr/local/sbin/kamctl fifo check_userblacklist blacklist oranjelaan.net 318001234 318001234:: blacklisted=true

[root@sip03 kamailio]# /usr/local/sbin/kamctl fifo check_userblacklist blacklist oranjelaan.net 318001235 318001235:: blacklisted=false

Have you done any tests to see if runtime works fine as well? Just to be sure nothing was broken.

Daniel,

Yes that seems to fix the problem. Kamailio now starts without crashing.

Thanks,

Jan

Can you try with the master branch or backport the next commit?

https://github.com/kamailio/kamailio/commit/5fd2c91f512b7311f11c76023da45758...

If all ok, then I push the backported patch to stable branches.

Cheers, Daniel

The spec is null, so the crash is obvious. I have to look at the code to see why it expect to be a spec there, while it can be a static string.

Cheers, Daniel
