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.
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.
To me, it is perfectly fine to run a simple, small utility in userspace even for testing.
No problem.
