Holger Hans Peter Freyther 5617d99388 gprs: Fix warnings on funny casts for the return statement 
Change gprs_nsvc_reset to return void instead of a int
as the gb_proxy.c currently ignores the reutnr value anyway.

Change the caller inside gprs_ns to return the newly allocated
nsvc instead of the return of gprs_nsvc_reset.

Harald Welte 90af194a9d [GPRS] NS: Always start NS-ALIVE procedure after RESET 
So far, we only started the ALIVE procedure on RESET-ACK if the
remote end was the SGSN.  This resulted in the BSS->Proxy connections
only being tested for alive-status from the BSS side, but not from
our side.

Also: export nsvc_by_nsvci() function as a public API function.

Harald Welte 731d1fc956 [GPRS] gb_proxy: Initiate RESET procedure on persistent NS-VC at startup 
Some BSS that connect to the proxy do not continue to perform the
RESET procedure after a timeout.  In order to resurrect them, we
simply start a RESET procedure.

Harald Welte 60cc6acaff [GPRS] NS: Remove 'unknown_nsvc' from list of NS-VCs 2010-05-13 14:20:56 +02:00
Harald Welte dd1c83c52d [GPRS] NS: Fix segfault when receiving message from unknown NS-VC 
In the previous code we used a static fake_nsvc structure in
case we needed to send a message to an unknown NSVC for which
we don't have a real 'struct nsvc'. However, since we now have
a rate_ctr_group hanging off the nsvc, the fake structure didn't
have that.

So now we keep a nsi->unknown_nsvc around to be used whenever
we need a nsvc but don't have a real one.  The gprs_ns_vty.c
code explicitly does not list that NSVC in 'show ns'

Harald Welte 144e0295c2 [GPRS] NS: Start to use rate_ctr_group code from libosmocore 
Every NS-VC now has a set of counters for incoming and outgoing
number of packets and bytes.

We also split the VTY part of the gprs_ns.c implementation into gprs_ns_vty.c
to make sure the protocol can actually be used without the VTY code being
present.

Harald Welte 91813cf214 GPRS: We have to do the msgb_free() in NS not Gb Proxy 
As only NS-UNITDATA messages are ever passed into the Gb Proxy,
we need to do the msgb_free() at a much higher point in the calling
stack, i.e. inside the NS protocol layer.  This means it is now
the same logic as in OpenBSC itself.

Harald Welte 2bffac599f NS: Add support for persistent NS-VC configuration 
With persistent NS-VC configuration (configured through VTY),
we can respond properly to BSS with a somewhat strange NS
implementation Such as the BSplus.  It enables us to respond
with a proper NS-RESET (including NSVCI/NSEI) when receiving
a NS-ALIVE or other PDU for a BLOCKED/DEAD NS-VC after our
end of the connection is rebooted.

Harald Welte 9a39293ced [gprs] gb-proxy: We might receive a NS-RESET for a NS-VC that we already know 
In this case, don't blindly allocate a new NS-VC but rather use the NSEI
to lookup the 'struct gprs_nsvc' for it.
