LCR: defunct_gw() is dangerous
by Iñaki Baz Castillo 24 Jan '12

24 Jan '12

Hi, I would like to share some experience using LCR under Kamailio 3.X in which there is no longer OPTIONS-based gateways monitorization. Now, the way to dissable a gateway is by calling defunct_gw() in a failure_route block (i.e. when there is no response for a request and fr_timer fires). So it's based on a single request processing. This is dangerous and I will put a real example: An ugly client sends us a request with a malformed P-Asserted-Identity as follows: P-Asserted-Identity(sip(a)domain.com Note that it's an *invalid* header. But Kamailio "allows" it and the request arrives to the GW. But the GW drops the request due to the malformed header so it sends NO reply at all. Then timeout occurs in the client transaction and failure_route block is called in which I call to defunct_gw(). Conclusion: an attacker could dissable my gws just by sending a simple malformed request. I strongly miss the monitorization feature in the old LCR module. And ever worse, I could make my own monitorization client by sending OPTIONS to all the gateways, but LCR module does not include a simple MI command to enable/dissable a gw so, what should I do? re-populate all the LCR tables and invoke LCR reload() MI command every time I detect a gw is offline/online?

Re: [sr-dev] [SR-Users] No memory left in send_subscribe (PUA) from update_pua while building the tm dlg_t structure

Hello Laura, I applied most of the patches, apart the second one for hash.c, related to checking for temporary dialog. I need to look a bit more at it, since there was some work in this regard: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commitdiff;h=b93… If I understood right, it is about NOTIFY getting processed faster than 200OK for SUBSCRIBE. Do I remember correctly, you are running 3.1.x? It might not be in branch 3.1. Cheers, Daniel On 12/28/11 6:15 PM, laura testi wrote: > Hi Daniel, > Yes, all patches are related to the PUA module.

onsend route also for replies
by Juha Heinanen 29 Dec '11

29 Dec '11

would it be a big deal to extend onsend route to work also on replies or introduce a new onsend_reply_route for that purpose? for example, i would like to be able to change response code/reason to something else in such a route based on some conditions (flags, avp values). -- juha

[tracker] Comment added: no avpops bigint handling breaks custom select queries

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. The following task has a new comment added: FS#193 - no avpops bigint handling breaks custom select queries User who did this - Daniel-Constantin Mierla (miconda) ---------- It is a matter of perspective, the issue is still here in a tracker, marked as an improvement request, so as soon someone will provide a patch or a developer will commit the enhancement, it will be closed, till then will be here. AVPs are from their beginning dealing with string or int values, someone has to know the underline db system to return such values if they are going to be stored in AVPs -- reason I don't see it as a bug, but enhancement request. Even now, there are so many DB types unsupported internally, as each db system has different types, not all standard. We cannot go through all possible db data types, for each version of db systems -- they change, new appear, a.s.o. ---------- More information can be found at the following URL: http://sip-router.org/tracker/index.php?do=details&task_id=193#comment481 You are receiving this message because you have requested it from the Flyspray bugtracking system.

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. The following task has a new comment added: FS#193 - no avpops bigint handling breaks custom select queries User who did this - Walter Doekes (wdoekes) ---------- > I am changing it in feature request, since avps are data structs to handle int and str values. I think that's a bit short sighted. Remember that I don't want any bigints. They're imposed on me by the SQL backend and/or driver, without any warning and without non-trivial workarounds. Having to create a mysql function that casts to a smaller int is not something immediately obvious when results are simply returned as <null> instead of an expected integer. I think it's a bug until it is transparently handled OR until the user is warned (a) that there is a problem (no bigint handling) and preferably (b) how to solve it.
