Harald Welte 91f7f4ba96 [GPRS] NS: Allow filtering of log messages by NSVC / NSEI 2010-05-15 23:52:02 +02:00
Harald Welte 24133c3958 [GPRS] NS: VTY: Don't nsvc_delete() on 'no nse...' 
Rather than deleting the NSE from memory, we simply mark it as non-persistent.
This makes sure that there are no invalid references (e.g. from gbprox_peer)
to the gprs_nsvc structure, but at the same time ensures it will no longer
be stored as part of writing the config file.

Harald Welte 92883345c8 [GPRS] NS: Introduce command to display a single NSE 2010-05-15 23:04:03 +02:00
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 a52ff459ec [VTY] Introduce "end" command that works from any level in config 
Using "end" you can always return to the "enable" level, and from
there the "show" commands are available.  So no more need for
exit/exit/exit/exit/disable.

Harald Welte 804fc81d2b [VTY] Remove OpenBSC specific node-exit handling from src/vty 
The idea is to move the VTY code into libosmocore at some point,
and for that we need to eliminate OpenBSC specifics from it

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 58e65c90a8 [GPRS] BSSGP: Refuse blocking of signalling BVC; Ignore traffic on blocked BVC 2010-05-13 21:45:23 +02:00
Harald Welte 25de811023 [GPRS] BSSGP: Make implementation more robust 
We now actually are much more in line with what the specification
says.  We track the blocked/unblocked state, we don't accept
signalling messages on PTP functional entities (and vice versa),
and we don't simply create a BVC context with messages other than
BVC-RESET.

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'
 2010-05-13 14:00:59 +02:00
Harald Welte d2dce6df04 [rate_ctr] always 'overflow' in next larger inetrval when interval ends 
If a second ends, we add the number of events in that just-ended second
to the number of events in the currently running minute.  The same happens
at the end of a minute: We add the number of events in that just-ended
minute into the number of events of the still-running hour, etc.

This gives a much more meaningful numbers and we don't end up with
"12 events per second, but 0 events per minute" kind of situations
anymore.

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 7b45d60887 Add new 'rate counter' implementation to libosmocore 
A 'rate counter' is a counter that counts events but also keeps
track of the rate of events (per second, minute, hour and day).

'rate counters' are generally abstracted in 'rate counter groups',
which are instances of a 'rate counter group description'.  This
way we can have e.g. a description describing what kind of counters
a BTS (or TRX) has - and we can then create one instance of that
group for every BTS or TRX that exists.

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.
