- Improved handling of extension-number string (as per review)
- Guard against a buffer-overflow if mobile sends a too-long USSD
- declare some function-parameters const
- fix gsm_ts_name function to display the right BTS number (bts->nr rather than bts->bts_nr)
This patch removes the need of static global variables and introduces a new,
caller-allocated 'struct ussd_request' that needs to be passed to the various
functions.
This is needed when you need to manually parse TLV blocks
that don't follow the logic supported by tlv_parse but you
still want to rely on working code and not fiddle with details.
bsc_init.c still contained a hard-coded channel configuration,
i.e. CCCH_combined on TS0 of C0, and TCH/F on all other channels.
Now it correctly uses the value as specified in the config file.
If we have a dynamic TCH/F / PDCH channel configuration, then
we can either ACTIVATE CHANNEL it for a TCH/F, or we need to send
this vendor-specific PDCH ACTIVATE command to use it as a PDCH.
As opposed to a fixed configuration, this allows an intelligent
BSC channel allocator to use otherwise idle channels as PDCH
as long as no more TCH's are needed.
Since TS 12.21 implements only SET ATTRIBUTE for some object classes,
ip.access had to extend it to be able to set attributes on arbitrary
objects. We now introduce a function implementing that message.
Supporting GPRS means we have a number of additional OML objects to
deal with. We need to extend our gsm_bts structure to at least
include the nm_state for each of those objects.
Tag-variableLength-Value is an encoding scheme used in the GPRS NS
and BSSGP protocols, where the length value can be 8 or 16 bits,
depending on actual demand.
For the compiler classmark1 is a struct and the compiler is
unaware that it fits into an unsigned int. Use memcpy to
copy it to a u_int8_t (the compiler should inline this).
dbi_conn_quote_binary_copy works on unsigned char* change
q_apdu to be unsigned char.
Commit 9bd7bc1b4c4a3ba42da46931df650837c1a7e889 caused the RSL
initialization to happen too early, resulting in the BTS
bootstrapping but missing [some of?] the system information
types.
In order to support multi-TRX configurations, we need to be able
to cope with multiple RSL streams (each with their own stream identifier)
inside one ip.access TCP connection.
Since this is very similar to using the TEI on a E1 line, we simply
recycle the logic and data fields that are used for the TEI.
Partially apply 9ba65525eaa06a1768aaf35bdee98afcf8026e0a to get
rid of a compile problem. The other part of the mentioned commit
is still in the gprs branch.

this fixes the delay of audio caused by stalling of the openbsc process.
the use of 'usleep(100000)' for slowing down transmission to nanoBTS is
replaced by the tx-delay timer. i did this on bs11 code, so i did it the
same way. it actually queues frames for transmission not nanoBTS. on
transmission a timer is started and when this timer expires, the next
frame in the queue is transmitted (timer restarted) until the queue is
empty.
