In Change-Id: I8c2c103cdc7f9a45d7b2080c572f559fc3db58e4 we introduced a check to enforce contention resolution always being used in MS-originated LAPDm establishment on the main DCCH / SAPI0. This is only required after RACH request (IMM.ASS.) and not after a normal assignment command which was sent already via a dedicated channel. Hence, we cannot enforce a strict requirement for contention resolution in those cases. We *could* use the RSL Channel Activation type as a constraint on whether or not to enforce contention-resoluiton-only LAPDm establishment, but this is out of the scope of the LAPDm code but would have to be done inside OsmoBTS.

libosmocore - set of Osmocom core libraries
This repository contains a set of C-language libraries that form the core infrastructure of many Osmocom Open Source Mobile Communications projects.
Historically, a lot of this code was developed as part of the OpenBSC project, but which are of a more generic nature and thus useful to (at least) other programs that we develop in the sphere of Free Software / Open Source mobile communications.
There is no clear scope of it. We simply move all shared code between the various Osmocom projects in this library to avoid code duplication.
The libosmcoore.git repository build multiple libraries:
- libosmocore contains some general-purpose functions like select-loop abstraction, message buffers, timers, linked lists
- libosmovty contains routines related to the interactive command-line interface called VTY
- libosmogsm contains definitions and helper code related to GSM protocols
- libosmoctrl contains a shared implementation of the Osmocom control interface
- libosmogb contains an implementation of the Gb interface with its NS/BSSGP protocols
- libosmocodec contains an implementation of GSM voice codecs
- libosmocoding contains an implementation of GSM channel coding
- libosmosim contains infrastructure to interface SIM/UICC/USIM cards
- libosmotrau contains encoding/decoding functions for A-bis TRAU frames
