Harald Welte c226317c9c add new new gprs_tmsi2tlli() function 2010-06-01 10:47:07 +02:00
Harald Welte 2f94683320 [GPRS] Include IMSI and DRX params in BSSGP DL-UD 
When we send a downlink unit-data request via BSSGP, there is a lot
of information that needs to be copied from the mm context, such as
the IMSI, DRX parametes, MS radio access parameters, ...

This is a quite strange layering violation, since we now need to pass
a pointer to the MM ctx from GMM through LLC into BSSGP :(

Harald Welte 1792532820 [GPRS] BSSGP: Fix way too long TLLI debug line 2010-05-31 20:18:35 +02:00

Harald Welte 2677ea547c [GPRS] BSSGP: When we receive a BLOCK, we should not respond with UNBLOCK-ACK 2010-05-31 17:16:36 +02:00

Harald Welte a8aa4df813 [GPRS] BSSGP: Acknowledge all SUSPEND and RESUME requests 
This is of course not the correct way of dealing with it, but for
now it should make the Ericsson Mobile Plafrom based phones happy
(they insist to do a suspend/resume cycle before pdp ctx act)

Harald Welte bd33f3d0ef [GPRS] NS: correctly pass the NS payload length to the TLV parser 2010-05-30 17:19:38 +02:00

Harald Welte f15497c1a3 [GPRS] NS: Don't hand Frame Relay LMI packets into the NS code 2010-05-28 16:12:57 +02:00
Harald Welte 57a9cf2797 [GPRS] NS: Respond to GRE keepalive messages 
GRE has the strange notion of keepalive messages being encapsulated IPv4
packets adressed back to the sender.  Since we actually really only care
about frame relay, this is a bit strange.  However, we'll do some sanity
checks and send it back through our GRE socket...

Harald Welte 3625038a11 [GPRS] NS: Print error message if TLV parser fails for some reason 2010-05-28 10:08:14 +02:00
Harald Welte c953120326 [GPRS] NS: Start TEST procedure, not ALIVE procedure, on RESET/RESET_ACK 
According to the spec, after an incoming RESET or RESET_ACK, we shall start the
TEST procedure, not the ALIVE procedure.

Also, when we start the TEST procedure, we have to always send a NS_ALIVE
packet at the same time (we didn't in the case of incoming RESET).

Furthermore, we now only start TIMER_TNS_ALIVE from within the
TIMER_TNS_RESET callback code, where we also make sure that the
alive_retries counter is reset to zero.

Holger Hans Peter Freyther 26c325151a gprs: Subtract the headroom for what we can receive 
The buffer got allocated with headroom and we need to
subtract that from the size of the buffer.

Holger Hans Peter Freyther e75a34faa5 gprs_ns.c: Make make_socket known to the compiler 2010-05-23 21:19:55 +08:00
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.

others return 0 even if we have a FIXME there.

Holger Hans Peter Freyther b6eded84fe gprs_bssgp.c: Cast const of TLVP_VAL away. 
Fix a compiler warning, we cast the const away at various
other parts in the code as well. We should consider removing
the const from the TLV struct..

vty parsing code

Harald Welte 8a521136a4 [GPRS] BSSGP: Rename bssgp_bts_ctx to bssgp_bvc_ctx 
The Context really is about a BVC (BSSGP Virtual Connection).  In
the case we operate BSSGP on the SGSN side, this corresponds to
a link to a BTS.
