<div bgcolor="#ffffff" text="#000000"> Hi Ronald,<br>
<br>
Thanks for the useful information - find
attached a patch that should fix the problem -
please apply it, recompile and let me know if
works ok - if yes, I will update on SVN.<br>
<br>
The crash seams to be triggered by a bogus SIP
message where the parsing of the first line
fails - and this message hits the pike route
crashing in some parsing functions.<br>
<br>
Regards,<br>
Bogdan

<div bgcolor="#ffffff"

<br>
The crash happens on a reply and
not a request - see the frame 14,
where "buf" (the buffer containing
the <br>
sip message) shows a reply like
text.<br>
<br>
But the is_method() should not
crash at all....before diving into
debugging:<br>
1) can you reproduce this
crash ?<br>
2) before the crash, do you
see any errors in the logs<br>
<br>
Regards,<br>

<div>Hi all,
<div><br>
</div>
<div>I'm using OpenSIPS
1.7.1 and based from the
attached back trace, it
crashed when it is trying
to parse the method of a
REGISTER message received
by the server, triggered
by pike route.</div>
<div> <br>
</div>
<div>Here is a snippet of my
opensips.cfg:</div>
<div>...</div>
<div>
<div>loadmodule "pike.so"</div>
<div>modparam("pike",
"sampling_time_unit",
30)</div>
<div>modparam("pike",
"reqs_density_per_unit",
75)</div>
<div>modparam("pike",
"check_route", "pike")</div>
</div>
<div>...</div>
<div>
<div>route[pike] {</div>
<div> if (($si ==
$Ri) || ($si ==
"192.168.1.60") || ($si
== " 192.168.1.61") ||
($si == "
192.168.1.65")) {</div>
<div>
drop;</div>
<div> }</div>
<div> if
(!is_method("REGISTER"))
{</div>
<div> drop;</div>
<div> }</div>
<div>}</div>
</div>
<div> ...</div>
<div><br>
</div>
<div>Basically, I just want
to check REGISTER messages
only on the pike route.
Does anyone have a
workaround on this?</div>
<div><br>
</div>
<div>FWIW, should I also
post this on the dev list?</div>
<div> <br>
</div>
<div>Thanks!</div>
