Pau Espin cd2ac56bd4 Remove undefined param passed to {logging,osmo_stats}_vty_add_cmds
Since March 15th 2017, libosmocore API logging_vty_add_cmds() had its
parameter removed (c65c5b4ea075ef6cef11fff9442ae0b15c1d6af7). However,
definition in C file doesn't contain "(void)", which means number of
parameters is undefined and thus compiler doesn't complain. Let's remove
parameters from all callers before enforcing "(void)" on it.
API osmo_stats_vty_add_cmds never had a param list but has seem problem
(no "void"), so some users decided to pass a parameter to it.

Alexander Couzens 5c3783b7e8 gprs_bssgp_pcu: explicit allocate & initialize bssgp_nsi instance
The instance bssgp_nsi is a global instance to be used by all
NS related functions. Previous the PCU allocated and initialized
the bssgp_nsi instance when (re-)connecting and freeing on disconnect.
The problem of the implicit initialisation is gprs_ns_vty_init(bssgp_nsi).
All vty init functions must be called before the configuration is read,
otherwise a previous vty written configuration is invalid.
Furthermore the vty modifications to the `ns` object were lost when the PCU has to
reconnect to the SGSN.

Max 41d6b35670 Add test for MS mode and (M)CS settings
Right now set_mode() on GprsMs behaves in pretty counter-intuitive way:
* it's possible to set current DL MCS higher than max value
* EGPRS and EGPRS_GMSK have the same max DL MCS
* setting EGPRS* mode drops current/max MCS values to unknown

Let's capture this in a unit-test before attempting any further
modifications.

Max e742cc0997 Use Timing Advance Index in UL assignments
Write TAI (if available) when generating Rest Octets for UL
Assignment. This should not affect actual PCU behavior because TAI is
not yet supported by upper layers but we have to adjust corresponding

Max 3eb47363ad Rewrite Packet Uplink IA Rest Octets for SBA
Use bitvec_set_*() directly without external write pointer tracking to
simplify the code. This is part of IA Rest Octets (3GPP TS 44.018
§10.5.2.16) which is the last part of the message so it should not
interfere with the rest of encoding functions.

The difference in the expected test output is due to proper handling of
TAI which should not be transmitted for SBA according to the Note in
Table 10.5.2.16.1 in 3GPP TS 44.018.

The change was manually tested against real mobile phone using options
'gprs mode gprs' in osmo-bsc.cfg and 'two-phase-access' in osmo-pcu.cfg
to make sure appropriate code path is actually triggered.

That's partially based on reverted commit 93d947f5e8.

Max 6e96dd4665 Fix Channel Coding Command for MCS
Previously result of ".to_num() - 1" was used without any checks which
means that in case of to_num() returning zero we would effectively try
to encode (uint8_t)(-1).

Let's fix this by using proper mcs_chan_code() function which returns
Channel Coding Command for MCS without the need to further correct it
and adjust expected tests output accordingly.

Stefan Sperling 082443d2c7 change log level of "DL packet loss" log messages
The TBF tests are failing on some machines due to unexpected
log output: "DL packet loss of IMSI= / TLLI=0xffeeddcc: 0%"
These messages are printed if >= 1 second has passed between
loss reports. This timing is machine-dependent so the test
is unstable as a result. Only print these messages at log
level debug to (hopefully) make TBF tests pass consistently.
Update expected test output accordingly.

Neels Hofmeyr 42f2d61ac9 use osmo_init_logging2() with proper talloc ctx
There is a duality of initialization: early_init() in bts.cpp wants to init
logging even before static instances get initialized. Make sure that
tall_pcu_ctx is initialized during early_init() as well. There is a build
context that does not seem to include bts.cpp (osmo-pcu-remote), so to be sure,
init tall_pcu_ctx as NULL and both in early_init() as well as pcu_main.cpp,
init both tall_pcu_ctx and logging if it is still NULL.

Max 2ecf0fdfc2 AllocTest: adjust test_alloc_b()
This function contains 3 independent test cases. Let's split them into
separate functions to simplify further modifications:

* split test cases into separate functions
* use them for mass test as well
* change function names to avoid confusion
* make individual test cases return error instead of failing via assert
  on allocation failure

The top-level test_alloc_b() is used as part of exhaustion tests in
test_all_alloc_b() for example, so it's expected that allocation might
fail (due to TFI or USF exhaustion for example) eventually. In this case
it's better to indicate it to caller instead of failing entire program.

The test output does not require any adjustements because we do not
exhaust to the point of allocation failure yet.
