[Olsr-users] OLSRd Runtime Issue

[Ferry Huberts]

I'm for not doing anything.
On my Fedora 19 machine the running flag is correctly set by
NetworkManager, so it seems that an older version had a bug.


I looked into this before and I seem to recall that I talked to you
about it Henning.

See
http://stackoverflow.com/questions/11679514/what-is-the-difference-between-iff-up-and-iff-running
and
http://www.xml.com/ldd/chapter/book/ch14.html#t3

I think for Linux we can remove the running flag but not for bsd.

I had some patches for this a while ago but dropped them.

Commit 6f25817dd2ceb18a8bdf95166885feab8b7cf84b introduced it.
IFF_UP and IFF_RUNNING are used in these 3 files:

src/unix/ifnet.c
src/linux/kernel_routes_nl.c
src/linux/net.c
