Move some Iu/A members into the MSC #ifdef.
Have separate allocate and free functions for the two scopes.

The diff between this and master will probably need a lot of review and fixes.
The current state does compile, but I expect pretty much everything to be
broken now. Future development will reinstate proper functionality piecemeal.
The first goal is to get basic signalling to work, then SMS. The voice control
(RTP) is completely disabled now (see "#if BEFORE_MSCSPLIT") and will be fixed
last AFAICT.

Pubish msc_compl_l3() decl in new file libmsc/msc_api.h (but see comment).
Call msc_compl_l3() when establishing a subscriber connection for IuCS.
Remove bts from subscr_conn_allocate_iu() signature, use network, link_id and
conn_id instead.
Move subscr_conn_allocate_iu() to the top of the file, because it semantically
belongs before subscr_conn_lookup_iu().

Add a comment of why we want to accept this connection anyway.

The idea of "subscriber_get_channel" was that different
requests would be coordinated. At the same time we have
seen that the "queue" can get stuck at both 31C3 and the
rhizomatica installations.
Voice calls and SMS do not need coordination. We should
be able to send SMS on a voice channel and switch the MS
from a SDCCH to a TCH in case we establish a voice call.
The SMS code itself needs to coordinate to obey the limit
of one SMS per direction but this should be enforced in
the sms layer and not on the subscriber.
Modify the code to have a simple paging coordination. The
subscriber code will schedule the paging and register who
would like to know about success/failure.
This allowed to greatly simplify the paging response
handling for the transaction code (and in fact we could
move the transaction list into the subscriber structure
now). The code gained to support to cancel the notification
of a request (but not the paging itself yet).
TODO: Cancel paging request in case no one cares about it
anymore.

Incoming DTAP messages from MS are discarded during silent calls,
which leads to the repeated delivery of SMS since the ACKs are not
being processed.
This patch adds some log messages that have been helpful to track
this down.

We were expiring subscribers during active calls. This is because
the T3212 is stopped under certain conditions but we didn't stop
that timer at all.
Remember if T3212 timer was stopped due something done by NITB and
update the expiration time at the end of the radio connection, as
the phone should restart it when returning to MM Idle.
It is a bit difficult to decide when we should set the flag. E.g.
in a CM Service Request we don't know if we accept the service and
during a LU we already send MM messages before we accept or reject
the subscriber.
The easiest is to set the flag when receiving a paging response
on known subscribers and at the end of the authentication process.
Do not expire a subscriber that has an active connection that is
marked with the flag, e.g. we would still expire a subscriber that
is being paged.
Manual tests executed/passed:
* gst LUTest.st verified that a expiration date was set
* gst SMSTest.st (doing another LU but forcing a timeout on the
SMS sending). Verified that the expire_lu was updated.

Remove the log messages and comments as they are wrong for now. Even
for the mode modify we will get the assign complete call.
|

This is more a work around and one still needs to implement a
proper dispatch on the opening of the connection. If there is no
operation left, no transaction and no silent call, close down the
channel.

RR Messages like STATUS, GPRS SUSPEND, HANDOVER COMPLETE/FAIL, ...
should be processed on the BSC side of things, not on the MSC side.
This is among other things required in preparation of intra-BSC
hand-over support in osmo-bsc.
|
|
This prevents osmo-bsc from sending RR messages to the MSC and rather
process them inside the BSC and turn them into BSSAP CM UPDATE.
|
|
The osmo-nitb application sometimes crashes because the BSC API
is doing an assignment underneath which is not handled by the code,
add dumy handlers to not crash, the right thing to do is to change
MNCC to have an assignment that can succeed/fail.
The keyword to look for is MNCC_LCHAN_MODIFY and mncc_sock should
wait for an ack/nack but right now the call just continues.

... and make sure tests work again after restructuring
