We don't really need openbsc/gsm_04_08.h or abis_rsl.h
But we do need some definition from libosmocore

Sylvain Munaut 0fbfd1bb52 gsm_04_08: Make gsm48_secure_channel available globally 
Can't declare it in gsm_04_08.h tough ... gsm_cbfn is defined in
gsm_data.h and trying to include that in gsm_04_08 just creates a
huge mess.

Holger Hans Peter Freyther 414bc4a1f4 mid-call: Do not lose the first word of the message 2010-11-26 00:06:58 +01:00
Holger Hans Peter Freyther cf6f71aa7f mid-call: Make the mid-call behavior the default for switching things off 
When switching the RF off we will always go through the grace
period, add a direct off mode to switch it off directly. Make
the query return a 'g' if we are in the process of switching
things over.
 2010-11-26 00:06:15 +01:00
Holger Hans Peter Freyther 70c232f75a mid-call: Implement a timer to go from grace to off.

Holger Hans Peter Freyther dab8e27755 ipaccess: Fix dropping the OML/RSL connection. 
Use the ipaccess_drop_oml and ipaccess_drop_rsl functions
instead of closing the socket and hoping this is picked up
somehow. This just leads to some weird hangs. And gdb was
not really helpful to say where it was coming from.

Holger Hans Peter Freyther 9c838ae069 bsc: Implement paging by creating a dummy subscr for the paging 
In the future we should avoid using a gsm_subscriber at all
and pass the imsi/tmsi to the paging function directly. For
now we can use the old model for paging and go through the
gsm_subscriber. This has the benefit of load balancing on
the BTS and such.
 2010-11-15 20:06:50 +01:00
Holger Hans Peter Freyther b79c3c97a2 bsc: The ip.access rtp-payload has no useful meaning 
Sending this as the RTP_PAYLOAD2 will produce a MDCX NACK
as we send the RTP_PAYLOAD in the CRCX. It does not seem to
be necessary to send anything != 0 for the RTP_PAYLOAD2.

Holger Hans Peter Freyther 863a55d44d bsc: Make bsc_queue_for_msc work on the osmo_bsc_sccp_con 
The gsm_subscriber_connection can die before the SCCP connection
so we should work on the osmo_bsc_sccp_con.

Holger Hans Peter Freyther 890dfc58ed bsc: Work on paging and parsing other messages 
The paging is not implemented due bad/missing API in the
BSC API, the rest are simple stubs to be merged from the
on-waves/bsc-master.

Holger Hans Peter Freyther 7e50c8140b bsc_api: Plug a theoretical window for the RLL callbacks 
The timedout could come between lchan_release and the
S_CHALLOC_FREED signal. In the future we might want to
use the gsm0808_clear to stop the RLL timeouts and such.

Holger Hans Peter Freyther 8d380dcadd bsc_api: Change submit dtap to allow to automatically use the SACH 
For SAPI=3 on a TCH it might be nice to use the SACH to submit
the message. The api allows to automatically use the SACH if
a message like this is submitted.

This will set the encryption algorithm, key and then
send the RR Cipher Mode message to the MS. The method
is also verifying the input.

Holger Hans Peter Freyther 2f169d64dd bsc_api: Make the cipher_mode take the 'include imei sv' argument

Holger Hans Peter Freyther e1996f013c bsc_api: The cipher mode is not a message on the air interface 
The cipher mode reject will be send in case the BSC is not
able to support the requested cipher. So this reject can be
handled by however attempts to enable ciphering.
 2010-11-15 20:06:46 +01:00
Holger Hans Peter Freyther 6c199e7d99 bsc_api: Look into the msg and call the right API functions 
For certain messages we will need to call other GSM0808 functions. To
keep the bsc_hack working we will try to send this through the normal
messages first and then fallback to dtap if no handler is registered.

The gsm_04_08.c code is not forced to handle the IPA activation
and channel modify ack anymore. This is done transparently by the
BSC API now.
 2010-11-15 20:06:46 +01:00
Holger Hans Peter Freyther fce9307553 bsc_api: Change the cause to a uint8_t for now 
The RR Cause can only be one byte. Change from uint16_t to uint8_t for that.
 2010-11-15 20:06:46 +01:00
Holger Hans Peter Freyther 05c68841a8 bsc_api: Fix a use after free error in the Clear Request path 
The implementation of bsc_hack would call subscr_con_free before
the BSC API has had the chance to call gsm0808_clear to try to
release other channels. Fix that by adding a return value.

Holger Hans Peter Freyther 8dfd241bc6 subscr: Add method to find an active subscriber 
This is used by the paging code of the osmo_bsc. When we get
a paging response there should be an active subscriber with
the TMSI or IMSI and we can stop paging. There is no need to
allocate a new subscriber.

Holger Hans Peter Freyther d740b688dc subscr: Add the subscr_get_or_create from the on-waves/bsc-master branch

Holger Hans Peter Freyther 928ca743db subscr: Move the TMSI reserved into the gsm_data

Holger Hans Peter Freyther 8cc59036e6 rsl: Allow to hardcode the RTP Payload 
In case of a inflexible network it is better to hardcode
the rtp payload to a given type. E.g. when using AMR5.9 on
a TCH/F and TCH/H having the same payload is helpful. For
now this will be only used by the osmo-bsc.

Holger Hans Peter Freyther ecd94a4b45 misc: Introduce a --enable-coverage mode to build with gprof coverage

which were not.

Holger Hans Peter Freyther 0b369c582b e1_input: Fix compiler warning by using offsetof 
Use the offsetof/__builtin_offsetof to determine the

Holger Hans Peter Freyther 1406977e7e nat: Verify that the endpoint from the assignment command exists 
Make sure that the MSC endpoint exists on the NAT, otherwise
we end up trying to free this endpoint when the SCCP connection
is taken down and will corrupt our memory. This issue started
to pop up as we have reduced the number of endpoints to 60
to allow transcoding on them.
