Composing the message type string requires knowing the protocol discriminator.
To ease printing the message type, add this function to switch between the
defined value_string[]s depending on pdisc.
Also publish the message type value_string[]s -- without inline functions to
access them because it is anyway more convenient to use
gsm48_pdisc_msgtype_name() instead.
Since gsm48_pdisc_msgtype_name() is nontrivial, do not add as inline function
-- in case the message type is not known, it needs a static string buffer.

I often want to log the protocol discriminator in the openbsc debug log. It's
more useful to get the name directly instead of looking it up every time.

There are some projects, such as GR-GSM and OsmocomBB, which would
benefit from using one shared implementation of GSM 05.03 code. So,
this commit introduces a new sub-library called libosmocoding, which
(for now) provides GSM, GPRS and EDGE transcoding routines, migrated
from OsmoBTS.
The original GSM 05.03 code from OsmoBTS was relicensed under
GPLv2-or-later with permission of copyright holders (Andreas Eversberg,
Alexander Chemeris and Tom Tsou).
The following data types are currently supported:
- xCCH
- PDTCH (CS 1-4 and MCS 1-9)
- TCH/FR
- TCH/HR
- TCH/AFS
- RCH/AHS
- RACH
- SCH

It is in the public header file and allows to easily bind it from
other languages (without having to go through the abstraction).

In the process, also:
* Change the license from AGPLv3 to GPLv2-or-later;
* correct spelling of 'sysmocom' to lowercase;
* add '2016' to the copyright;
* rename to osmo_*;
* add API docs;
* add logging category DLOAP: define id and add to internal_cat;
* redirect all oap.c logging to DLOAP.
A unit test will follow in a subsequent patch, since it needs a minor tweak for
decoding of boolean values.

Add two functions to create USSD messages. Moves and generalizes code from
openbsc. Pending: use the new functions in openbsc.
It looks like _release_complete() should also set trans_id and direction flag;
but since this is moving code from openbsc that is apparently working, just
place a fixme comment and don't change the functionality.

Context: in osmo-bts, I want to look up an RSL message name in rsl_msgt_names
and fall back to rsl_ipac_msgt_names if not found, because the IPAC PDCH ACT
and DEACT messages are sent in a standard ABIS_RSL_MDISC_DED_CHAN.

Move those routines from OpenBSC to libosmogsm, so they can be
re-used from other programs. I think it was a mistake to add them only
inside the openbsc repository in the first place. We need to pay more
attention to this in the future.
|
|
|
|
|
| |
These routines have nothing to do with specifically the BSC, so import
them to the TLV parser we keep in libosmogsm.

Add python utility to generate .c code with convolutional
encoder/decoder based on polynomial description of the code. If argument
given it'll be interpreted as intended output directory, otherwise
current working directory is used.
Codes for *CCH, CS2/3 and TCH/AFS are generated. Corresponding manual
implementations are removed from tests. This introduce build-time
dependency on python.
The main work for this patch was generously contributed by Sylvain
Munaut.

For 3G, I need a BCD composer/parser similar to gsm48_generate_lai()/
gsm48_decode_lai(). Those functions also handle a trivial extra
member (lac) which I don't need in this way for 3G.
So create new functions to take on the MCC+MNC BCD handling and call those
from gsm48_generate_lai() and gsm48_decode_lai(). In this way, the 3G code
in openbsc can use only the BCD functionality without code duplication.
