Initializes primitive's header, setting the logical channel type and the payload length. After initialization, the talloc context of a primitive is a trx instance, which passed as the first argument. - sched_trx_push_prim() - decodes the timeslot index from chan_nr and pushes a primitive to its transimt queue. The talloc context of primitive is changed to the parent trx_ts instance after queuing. Both functions will be used for handling both L1CTL_TRAFFIC_REQ and L1CTL_RACH_REQ.

It may be extremely useful for testing and development of GSM stack, including both sides (MS and BTS). This software implements OsmoTRX (Osmocom's fork of OpenBTS transceiver) style clock (CLCK), control (CTRL) and data interfaces. So, OsmoBTS source code doesn't require any modifications, while for OsmocomBB you will need to use a new application - trxcon, which can be found in the 'fixeria/sdr_phy' branch until one is merged to master. Brief description of available applications: - fake_trx.py - main application, that allows to connect both OsmocomBB and OsmoBTS without actual RF hardware. Currently only a single MS may work with a single BTS. - clck_gen.py - a peripheral tool aimed to emulate TDMA frame clock generator. Could be used for testing and clock synchronization of multiple applications. It should be noted, that one relays on generic system timer (via Python), so a random clock jitter takes place. - ctrl_cmd.py - another peripheral tool, which could be used for sending CTRL commands directly in manual mode, and also for application fuzzing.

This state machine handles different events, raised from program modules (such as trx_if.c or l1ctl.c). - l1ctl_link_fsm - L1CTL server state machine. - trx_interface_fsm - TRX interface state machine. The program modules (such as trx_if.c or l1ctl.c) should be as much independent from each other as possible. In other words, one module should not call methods from another, e.g. L1CTL handlers are not able to send any command to transceiver directly. Instead of that, they should use shared event set to notify the main state machine about something. Depending on current state and received event, main state machine 'decides' what to do. This approach would allow to easily reuse the source code almost 'as is' anywhere outside the project.

One of them is the L1CTL interface, which is used by existing layer23 applications to drive GSM L1. Exactly this interface is provided by the osmocon application, but instead of forwarding messages between both host software and firmware we need to handle incoming messages from layer23 applications, perform some GSM L1 specific conversations (coding, mapping, interleaving, etc.), then finally forward them to transceiver through the scheduler. And vice versa. This code is just a basic implementation of UNIX socket handlers, so currently we can only accept and drop connections from layer23 applications.
