Reload subnet config with HUP signal

[Armin Schindler]

Hi,

I need to re-open the thread blow. The situation is still the same.
The HUP signal does not trigger reloading of subnet declarations in own
hosts file (Version 1.0.35).
After a quick view to the source code, file src/net.c shows in line 658
would reload subnets when using StrictSubnets only.
But why? With StrictSubnets it doesn't make sense to me.

I did a quick check and removed the
  if (strictsubnets)
to let HUP signal reload sunets and it works.

So why is the update of local subnet declaration with HUP signal possible in
StrictSubnet mode only?

it doesn't work. tincd doesn't reread the its hosts config file to
get the new Subnet settings.
I rewrote the hosts/<my host> file (adding a Subnet) and sent
the HUP signal. But with USR2 signal, each node and the local itself
doesn't show anything about the new Subnet entry.
Did I miss something?
I need to stay with version 1.0.
