Hi Harald,

It's not that far away, we can just create the udp socket from
kernelspace via udp_sock_create() in the test mode. So we don't need
to pass the file descriptor from userspace. But not asking you to work
on this, just an idea.
I've modified the patch slightly, see below
(compile-tested, but not
otherwise tested yet). Basically rename the flags attribute to 'role',
expand the commit log and removed unrelated cosmetic changes.
I've also prepared a corresponding change to libgtpnl into the
laforge/sgsn-rol branch, see
http://git.osmocom.org/libgtpnl/commit/?h=laforge/sgsn-role
This is not yet tested in any way, but I'm planning to add some
associated support to the command line tools and then give it some
testing (both against the kernel GTP in GGSN mode, as well as an
independent userspace GTP implementation).
Thanks Harald.
It would be
good if we provide a way to configure GTP via iproute2 for
testing purposes.
I don't really care about which tool is used, as long as it is easily
available [and FOSS, of course].
We would need to create some dummy socket from
kernel too though so we don't need any userspace daemon for this
testing mode.
I don't really like that latter idea. It sounds too much like a hack to
me. But then, I don't have enough phantasy right now ti imagine how an
actual implementation would look like. To me, it is perfectly fine to run a simple, small
utility in userspace
even for testing.
No problem.
