Hi All,
Looking for some guidance on debugging and also reporting a bug.
First off I can't seem to find any information on reproducing the ubuntu
16.04 build with debug symbols, I do have a core file I'd like to
introspect to potentially provide a patch.
Secondly the bug report itself:
I am receiving a segfault signal 11 when one or more machines share a
*Address* specific IP.
For various reasons in our deployment case we have a special Wired VLAN IP
address for connecting to PCs that is shared. Normally machines are only
connected via Wifi.
There is a backup options for connecting where tinc still needs to function
for various reasons and over the wired connection.
Sometimes there is a case where the secondary fallback Address is used and
a segfault occurs.
Example host file for HOSTA:
Address = HOSTA
Address = 10.254.254.1
<snip key>
Example host file for :
Address = HOSTB> Address = 10.254.254.1
> <snip key>
Relevant Syslog:
Jun 1 18:10:09 HOSTA tinc.robotvpn[6844]: Peer 10.254.254.1 port 655
is> HOSTA instead of HOSTB
> Jun 1 18:10:09 HOSTA tinc.robotvpn[6844]: Error while processing ID from
> HOSTB (10.254.254.1 port 655)
> Jun 1 18:10:09 HOSTA tinc.robotvpn[6844]: Got fatal signal 11
> (Segmentation fault)
>
If either compiling in debug can help decode the core file or more detailed
log information is available I can look to supply a patch or further
information.
Thanks,
