Hello!
Spent a few minutes looking up what's going on in the situation
described in http://bugs.debian.org/582680
Around line 420 in ip/iptunnel.c there's code to look in /proc/net/dev
for interface names, look up their "index" from the name (via ll_name_to_index
helper function) and then type from index (via ll_index_to_type)
to finally do:
if (type != ARPHRD_TUNNEL && type != ARPHRD_IPGRE && type != ARPHRD_SIT)
continue;
Apparently (regular) GRE tunnels return type ARPHRD_ETHER,
which is the same as a (real) ethernet interface....
I don't know how to detect if an interface is backed by a real ethernet
interface or if it's ethernet over a gre tunnel. Apparently just using
ll_index_to_type is not enough for that....
Any hints on how to do that would be welcome! :)
