ms: Make ms_{attach,detach}_tbf expectancies more robust * Make sure that the tbf being attached has already the MS assigned. * Check no re-attaching of alredy attached TBF ever happens. * Document and early skip case where a non-attached TBF detach is attempted. * Avoid recursive call mess to tbf_set_ms(tbf, NULL); during detach. * MsTest needs to be modified since it uses fake TBF objects which use different set of calls than the regular TBFs in osmo-pcu. Since the ul_tbf object is reused, it needs to be assigned ul_tbf->ms again before re-assigning it, as per what happens usually in tbf_set_ms() in osmo-pcu.

This repository contains a C/C++-language implementation of a GPRS Packet Control Unit, as specified by ETSI/3GPP. It is part of the Osmocom Open Source Mobile Communications project.
The Packet Control Unit is terminating the Layer 2 (RLC/MAC) of the GPRS radio interface and adapting it to the Gb Interface (BSSGP+NS Protocol) towards the SGSN.
The PCU interfaces with the physical layer of the radio interface. OsmoPCU is typically used co-located with the BTS, specifically OsmoBTS. For legacy BTSs that run proprietary sotware without an interface to OsmoPCU, you may also co-locate it with the BSC, specifically OsmoBSC
The official homepage of the project is https://osmocom.org/projects/osmopcu/wiki/OsmoPCU
You can clone from the official osmo-pcu.git repository using
git clone https://gitea.osmocom.org/cellular-infrastructure/osmo-pcu
There is a web interface at https://gitea.osmocom.org/cellular-infrastructure/osmo-pcu
We provide a user manual as well as a vty reference manual
Please note that a lot of the PCU configuration actually happens inside the BSC, which passes this configuration via A-bis OML to the BTS, which then in turn passes it via the PCU socket into OsmoPCU.
