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 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)

Holger Hans Peter Freyther d30cefaac1 gprs_bssgp.c: Return something from non void methods. 
In one use the rc variable we are assigning to, in the
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..

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.

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 af0867882d [gprs] gb_proxy: Send proper BSSGP STATUS msg in error case 
In order to reuse the existing bssgp_tx_* functions without pulling
in the dependencies of gprs_bssgp.c, we have to move those functions
to gprs_bssgp_util.c

Furthermore, we can remove gbprox_nsi and replace it with bssgp_nsi,
and we can do proper processing of BVC-RESET messages coming from
the SGSN on the signalling BVC.  In that case we need to send RESET
messages to all the BSS.
