[kamailio/kamailio] Kamailio 5.6.0 crash when removing non-existing node from the dispatcher (Issue #3199)

by Denys Pozniak

### Description When deleting a node that does not resolve through the DNS and that does not exist in the dispatcher table, a Kamailio crash occurs. #### Reproduction 1. Create set id with one existing node in dispatcher table (DB MySQL) (for example sip:10.1.0.6 in set 200) 2. Reload dispatcher table: `kamcmd dispatcher.reload` 3. Delete a non-existent and non-resolvable node via kamcmd: `kamcmd dispatcher.remove 200 sip:127.0.0.1.test` ERROR: read reply failed: Success (0) 5. Kamailio crashed #### Debugging Data bt full info locals list ``` GNU gdb (GDB) Red Hat Enterprise Linux 7.6.1-120.el7 Copyright (C) 2013 Free Software Foundation, Inc.

by lglhust

ubuntu 18.04 , kamailio v5.3.8 : UE A and B register sucess on kamailio server over tcp. When UE A calls UE B, kamailio server receive the INVITE over tcp from UE A, then it send invite to UE B. But the invite sent by kamailio to UE B is over UDP. Then UE B returns ICMP Destination unreachable(Port unreachable). Is the error configuration related or a bug? Any kind of help is highly appreciated.

[kamailio/kamailio] set_contact_alias() doesn't work as promised (Issue #3201)

by Alex Hermann

### Description The docs for `set_contact_alias()` says: > **The new contact URI is immediately visible to other modules** in the way the fix_nated_contact() does it. I don't know exactly what is meant by the last part of that sentence as that isn't documented, but the first part certainly doesn't hold: The following snippet: ``` xlog("L_INFO", " Received Contact: $ct"); if (set_contact_alias()) { xlog("L_INFO", " Aliassed Contact: $ct"); } ``` Causes these log entries: ``` 2022-07-26T15:41:57.351148+02:00 proxydev001 prx1[12116]: INFO: Received Contact: sip:sipp@unknowndomain;transport=udp 2022-07-26T15:41:57.351148+02:00 proxydev001 prx1[12116]: INFO: Aliassed Contact: sip:sipp@unknowndomain;transport=udp ``` Which clearly shows that the changed uri is **not visible** to the `pv` module (which exports `$ct`). -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3201 You are receiving this because you are subscribed to this thread.
