a2828fa4bc bsc_api: Set the lchan->conn to NULL in all of the cases 2010-11-15 20:06:47 +01:00

088dde8173 bsc_api: Send a channel modify when we already have a TCH. 2010-11-15 20:06:47 +01:00

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.

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.

4be7d41a50 bsc_api: Implement sending the cipher mode method 
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.

2f169d64dd bsc_api: Make the cipher_mode take the 'include imei sv' argument 
The cipher mode command should enable encryption and send the
right RR message to the other side.

66dcd925c6 bsc_api: Nuke the clear complete from the API. 
There is no place where it can be called. Whoever is calling
the gsm0808_clear method should generate the clear complete
as the result.

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.

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.

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.

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.

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.

d740b688dc subscr: Add the subscr_get_or_create from the on-waves/bsc-master branch 
Create a subscriber based on a known IMSI, search the list of
active subscribers if there is already someone like this.

928ca743db subscr: Move the TMSI reserved into the gsm_data 
Put it into the gsm_data.h to avoid requiring MSC code

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.

ecd94a4b45 misc: Introduce a --enable-coverage mode to build with gprof coverage 
This adds a test coverage build. One can use gcov and lcov on the
resulting data afterwards to see which code paths were executed and
which were not.

0b369c582b e1_input: Fix compiler warning by using offsetof 
Use the offsetof/__builtin_offsetof to determine the
offset of a variable inside a structure instead of going
via a NULL pointer and taking the address.

This fixes:
warning: variably modified ‘dummyhalen_offset’ at file scope

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.

e97155a2af mgcp: Keep the local_port like it was set on allocation 
Do not reset statically allocated local_port. The port
might be different to the calculation of endpoint number
and base port. This might be the case for the coming remote
transcoding.

54f5352e07 nat: Close SCCP connections when the USSD Provider is closed. 
Send a RLSD down to the BSC in case the USSD Provider is gone. It
is not sending a Clear Command and ut depends if the BS+ will
like this kind of behavior. At least the data on the NAT will
be freed soon afterwards due the RLC message.
