Delete default route from main on SIGTERM #56

Closed genofire closed 4 years ago

genofire commented 5 years ago

The routing entry at table main disapear: default via 2a02:16d0:1003:700::1 dev ens3

state before SIGTERM:

 echo "get_prefixes" | socat - unix:/var/run/l3roamd.sock
{ "prefixes": [ "::ffff:0.0.0.0", "2a06:8782:ffbb:bab1::", "fe80::" ] }

I am little bit confused, maybe this is the solution:

Why is he deleting from 254 and not from given l3ctx.clientmgr_ctx.export_table https://github.com/freifunk-gluon/l3roamd/blob/3c7b4447aece012093a7e50653835cca4e48c953/src/main.c#L67

L3roamd writes to the main routing table when new prefixes are added because those prefixes should be made available.

I agree, when specifying -t then only this table should be used.
