The 'show statistics' VTY command was not showing all counters
maintained by osmo-bsc. Instead of printing just two counters
related to paging, print all available counters in a generic way.
Adjust descriptions of some counters for nicer display.
After startup (all counters are zero) is now looks like this:
OsmoBSC# show statistics
handover:attempted: 0 Received handover attempts.
handover:no_channel: 0 Sent no channel available responses.
handover:timeout: 0 Timeouts of timer T3103.
handover:completed: 0 Received handover completed.
handover:failed: 0 Received HO FAIL messages.
paging:attempted: 0 Paging attempts for a subscriber.
paging:detached: 0 Paging request send failures because no responsible BTS was found.
paging:responded: 0 Paging attempts with successful response.

The function a_reset_free() is not used anywhere at the code. The
reason for this is that a BSC instance is never cleared once it
is started up. Also the timer number is not according to the spec.
- Remove a_reset_free()
- Fix timer identification number (T4)
- use fi->priv to hold context info
- Fix sourcecode formatting

Recent Icf6e25ff068e8a2600562d52726ead65e864ec02 changed the dyn_ts_init() hook
from bootstrap_rsl() to the Channel OPSTART ACK, but this is not sufficient.
Now RBS2k never calls dyn_ts_init(), and we may need to wait for RSL:
Dyn TS should actually be initialized only when *both* OML opstart and RSL link
are established. To that end, introduce a generalized API to query OML and RSL
status and to trigger a timeslot init at the appropriate time.
Add gsm_ts_check_init() to be called both when RSL and OML opstart are
established: trigger gsm_ts_init() only when both are given.
Add gsm_bts_trx_ts->initialized flag to mark whether initialization has already
taken place. Add gsm_bts_mark_all_ts_uninitialized() to conveniently clear this
flag for all TS in a BTS.
Add gsm_bts_model.oml_is_ts_ready() callback so that each BTS implementation
can return the OML status of a timeslot in its own OML implementation.
Actually, currently all BTS models that need this init mechanism store the TS'
OML status in ts->mo.nm_state. While we would in practice correctly init dyn TS
by just looking at ts->mo.nm_state, semantically, the decision whether the TS
is ready is up to the BTS models' specific OML implementations.
From bootstrap_rsl(), call gsm_ts_check_init(), in case the TS OML Opstart has
happened before RSL is established -- applies to all BTS models.
For all BTS models:
- call gsm_{bts,trx}_mark_all_ts_uninitialized() when OM is torn down, to make
sure the TS init mechanism will work a second time.
For all BTS models supporting dyn TS, i.e. osmo-bts, nanobts and RBS2k:
- implement oml_is_ts_ready().
- call gsm_ts_check_init() when a Channel OM is taken into operation.
Any BTS models that don't set oml_is_ts_ready() will see a ts init as soon as
RSL is bootstrapped (incidentally, the old dyn TS behavior before recent
Icf6e25ff068e8a2600562d52726ead65e864ec02).
This firstly fixes dyn TS for RBS2k by re-adding the initial switch to PDCH,
and furthermore does so only after both OML TS opstart and RSL are through.
This fixes the ttcn3-bsc-tests around dyn TS, since for the osmo-bts-virtual,
the RSL is established only after OML opstart on the TS, which was broken by
Icf6e25ff068e8a2600562d52726ead65e864ec02.
Nokia Site and Siemens BS11 practically do not require this init mechanism,
since all that happens there so far is dyn TS init, and these BTS models do not
support dyn TS of any kind. A future patch may add oml_is_ts_ready().

Sending PDCH activation upon RSL bootstrap is too early. Introduce OPSTART ACK
handling to call dyn_ts_init() only when the dynamic timeslot is indeed ready
to receive a PDCH activation.

At this point, meas-feed is usable again, however, osmo-bsc is not able to
include the IMSI in every report like osmo-nitb did.
In consequence, the meas-vis and meas-web tools are unable to handle the
current measurement reports: these so far use the IMSI to list reports, and all
reports without an IMSI are collapsed onto the same line, swapping values.
So though osmo-bsc now sends usable measurement reports via meas-feed, two
avenues to improve should be pursued:
OS#3192: the visualization tools should use bts,ts,ss numbers, not IMSI.
OS#2969: osmo-bsc should always know a mobile identity.

There are plans to register signal handlers in acc_ramp_init(). Once we
do that, the acc_ramp_init() function should only be called once to
avoid duplicate signal handlers on the handler list.
However, the acc_ramp_init() function currently serves a dual-purpose:
1) Initialize the acc_ramp structure for a bts
2) Enable or disable ACC ramping
Add new functions to support use case 2, and call acc_ramp_init()
just once while reading the configuration file. The VTY commands
which enable/disable ACC ramping use the new APIs instead.
Also, rename acc_ramp_start() to acc_ramp_trigger() and tweak its
semantics so that it can always be called regardless of what the
current configuration settings are. This prepares us for triggering
ACC ramping upon events other than "RSL link-up".

Correctly compute the TS 48.008 "speech mode" (codec) for AMR on TCH/F.
There are way too many different ways how to express a given voice
codec. There are two different schemes in TS 48.008 alone, plus one
on TS 48.058 and one in 04.08 / 44.018. Let's avoid unneeded
conversion (that we might get wrong) and avoid storing information in
a sub-struct of the lchan if we can simply derive it from the lchan
at the time we need it.
Also, move BSSAP related encoding/conversion functions closer to the
user (osmo_bsc_bssap), rather than in libbsc.
Without this patch, TCH/F with AMR was erroneously reported as TCH/H
with AMR in the BSSMAP ASSIGNMENT COMPLETE. After this patch, it's
reported correctly.

In the current implementation of osmo-bsc, the subscriber connection is
not handled (very) statefully. However, there is some state keeping in the
code that handles the mgcp connection, but there are still to much loose ends
which allow odd situations to happen, which then lead severe error situations
(see also closes tags at the end) This commit adds a number of improvements
to fix those problems.
- Use an osmo-fsm to control the gsm_subscriber_connection state and
make sure that certain operations can only take place at certain states
(e.g let connection oriented SCCP traffic only pass when an SCCP connection
actually exists.
Remove the old osmo_bsc_mgcp.c code. Use the recently developed MGCP client
FSM to handle the MGCP connections.
Also make sure that stuff that already works does not break. This in
particular refers to the internal handover capability and the respective
unit-tests.
See also OS#2823, OS#2768 and OS#2898
- Fix logic to permit assignment to a signalling channel. (OS#2762)
- Introduce T993210 to release lchan + subscr_conn if MSC fails to respond
The GSM specs don't have an explicit timer for this, so let's introdcue
a custom timer (hence starting with 99).
This timeout catches the following situation:
* we send a SCCP CR with COMPL_L3_INFO from the MS to the MSC,
* the MSC doesn't respond (e.g. SCCP routing failure, program down, ...)
The MS is supposed to timeout with T3210, 3220 or 3230. But the BSC
shouldn't trust the MS but have some timer on its own.
SCCP would have a timer T(conn est), but that one is specified to be
1-2min and hence rather long.
See also: OS#2775
- Terminate bsc_subscr_conn_fsm on SCCP N-DISC.ind from MSC
If the MSC is disconnecting the SCCP channel, we must terminate the FSM
which in turn will release all lchan's and other state.
This makes TC_chan_rel_hard_rlsd pass, see also OS#2731
As a side-effect, this fixes TC_chan_act_ack_est_ind_refused(),
where the MSC is answering with CREF to our CR/COMPL_L3.
- Release subscriber connection on RLL RELEASE IND of SAPI0 on main DCCH
The subscriber connection isn't really useful for anything after the
SAPI0 main signalling link has been released. We could try to
re-establish, but our best option is probably simply releasing the
subscriber_conn and anything related to it.
This will make TC_chan_rel_rll_rel_ind pass, see also OS#2730

Add 3-digit flags and use the new RAI and LAI API from libosmocore throughout
the code base to be able to handle an MNC < 100 that has three digits (leading
zeros).
The changes to abis_test and gsm0408_test show that this code now handles
3-digit MNC correctly, by not dropping the leading zero as 0xf in the encoded
PLMN.
Re-implement CTRL commands 'mcc', 'mnc' and 'mcc-mnc-apply' to preserve the
presence of the third digit of the MNC. Always reply with all leading zeros.
Adjust the expected results in ctrl_test_runner.py, to show that it works.
In VTY and CTRL, the parsing of MCC and MNC is inherently made stricter by use
of osmo_{mcc,mnc}_from_str() -- they will no longer allow surplus characters
and detect errno returned by strtol() (in contrast to atoi()).

Move from using deprecated gsm48_construct_ra(), which uses a buf, to
gsm48_encode_ra(), which uses a gsm48_ra_id argument. Pass struct gsm48_ra_id
around instead of a buf.
struct gsm48_ra_id is the "encoded" representation of the bytes in a typical
MCC-MNC-LAC-RAC (04.08 Routing Area Id IE, 3GPP TS 24.008 ยง 10.5.5.15). Using
the struct spares using magic numbers for byte offsets.
In the process, fix a sanitizer warning for unaligned access by using memcpy()
instead of pointer assignment:
osmo-bsc/src/libbsc/abis_nm.c:2857:27: runtime error: store to misaligned address 0x7ffe8e0d6695 for type 'uint16_t', which requires 2 byte alignment
Note that (besides removing a now unnecessary cast) the gsm0408_test and
abis_test tests of RAI / CGI encoding remain stable, which indicates that the
new code is still correct.

Access Control Class (ACC) ramping is used to slowly make the cell
available to an increasing number of MS. This avoids overload at
startup time in cases where a lot of MS would discover the new
cell and try to connect to it all at once.
Ramping behaviour can be configured with new VTY commands:
[no] access-control-class-ramping
access-control-class-ramping-step-interval (<30-600>|dynamic)
access-control-class-ramping-step-size (<1-10>)
(The minimum and maximum values for these parameters are hard-coded,
but could be changed if they are found to be inadequate.)
The VTY command 'show bts' has been extended to display the
current ACC ramping configuration.
By default, ACC ramping is disabled.
When enabled, the default behaviour is to enable one ACC per
ramping step with a 'dynamic' step interval. This means the
ramping interval (time between steps) is scaled to the channel
load average of the BTS, i.e. the number of used vs. available
channels measured over a certain amount of time.
Below is an example of debug log output with ACC ramping enabled,
while many 'mobile' programs are concurrently trying to connect
to the network via an osmo-bts-virtual BTS. Initially, all ACCs
are barred, and then only one class is allowed. Then the current
BTS channel load average is consulted for scheduling the next
ramping step. While the channel load average is low, ramping
proceeds faster, and while it is is high, ramping proceeds slower:
(bts=0) ACC RAMP: barring Access Control Class 0
(bts=0) ACC RAMP: barring Access Control Class 1
(bts=0) ACC RAMP: barring Access Control Class 2
(bts=0) ACC RAMP: barring Access Control Class 3
(bts=0) ACC RAMP: barring Access Control Class 4
(bts=0) ACC RAMP: barring Access Control Class 5
(bts=0) ACC RAMP: barring Access Control Class 6
(bts=0) ACC RAMP: barring Access Control Class 7
(bts=0) ACC RAMP: barring Access Control Class 8
(bts=0) ACC RAMP: barring Access Control Class 9
(bts=0) ACC RAMP: allowing Access Control Class 0
(bts=0) ACC RAMP: step interval set to 30 seconds based on 0% channel load average
(bts=0) ACC RAMP: allowing Access Control Class 1
(bts=0) ACC RAMP: step interval set to 354 seconds based on 59% channel load average
(bts=0) ACC RAMP: allowing Access Control Class 2
(bts=0) ACC RAMP: step interval set to 30 seconds based on 0% channel load average
(bts=0) ACC RAMP: allowing Access Control Class 3
(bts=0) ACC RAMP: step interval set to 30 seconds based on 0% channel load average

Instead of reacting on S_LCHAN* signals in the handover decision code,
introduce callbacks for the handover decision to be invoked by handover_logic.c
at the appropriate time.
The rationale is explained in a comment to struct handover_decision_callbacks,
quoting:
"
All events that are interesting for handover decision are actually communicated
by S_LCHAN_* signals, so theoretically, each handover algorithm could evaluate
those. However, handover_logic.c cleans up handover operation state upon
receiving some of these signals. To allow a handover decision algorithm to take
advantage of e.g. the struct bsc_handover before it is discarded, the handover
decision event handler needs to be invoked before handover_logic.c discards the
state. For example, if the handover decision wants to place a penalty timer
upon a handover failure, it still needs to know which target cell the handover
failed for; handover_logic.c erases that knowledge on handover failure, since
it needs to clean up the lchan's handover state.
The most explicit and safest way to ensure the correct order of event handling
is to invoke the handover decision algorithm's actions from handover_logic.c
itself, before cleaning up. This struct provides the callback functions for
this purpose.
For consistency, also handle signals in this way that aren't actually in danger
of interference from handover_logic.c (which also saves repeated lookup of
handover state for lchans). Thus, handover decision algorithms should not
register any signal handler at all.
"
Also:
- Publish struct bsc_handover to use it as argument to above callbacks.
- Add enum hodec_id to struct bsc_handover, to be able to signal the
appropriate hodec algorithm per event.
- Add hodec_id argument to bsc_handover_start*() to be placed in the
bsc_handover struct.
- Publish the LOGPHO logging macros in handover.h along with struct
bsc_handover, convenient for logging in callback implementations.
Replace handover_decision.c's signal handler with a registered
handover_decision_callbacks instance.
(Upcoming handover_decision_2 will use all of the callbacks introduced here.)

The conn's penalty timers will be used only for handover decision 2, make it

hodec2 will also initialize the penalty timer list on demand only, so no need
to always initialize.

Do not share config items between the current handover decision and the
upcoming handover_decision_2.
Rename current handover config items to hodec2_* and duplicate the ones
relevant to handover decision algorithm 1 with name prefix of hodec1_*.
I considered moving hodec2 parameters to an entirely separate .c file and
struct, but that causes considerable code bloat. Rather use the nice
handover_cfg net/bts level mechanism as-is, and simply prefix the names.
In the VTY, the hodec1 parameters are configurable by 'handover foo 23'
commands, while the hodec2 parameters are by 'handover2 foo 23'. The generic
VTY commands to enable/disable handover and to choose the algorithm are still
'handover (0|1)' and 'handover algorithm (1|2)'.
(Note, a subsequent commit will rename the 'handover foo' for hodec1 to
'handover1 foo' and add backwards-compat aliases.)
For example, the 'window rxlev averaging 5' command now exists both for
handover decision 1 and handover decision 2, and its values are independent.
This is valid config:
network
# set up handover decision algorithm 1
# (pending rename of these items to 'handover1 ...')
handover window rxlev averaging 5
handover window rxlev neighbor averaging 5
# set up handover decision algorithm 2
handover2 window rxlev averaging 7
handover2 window rxlev neighbor averaging 7
handover2 penalty-time max-distance 10
# enable handover
handover 1
bts 0
handover algorithm 1
bts 1
handover algorithm 2
In this example, bts 0 uses algo 1 with rxlev averaging of 5, while bts 1 uses
algorithm 2 where rxlev averaging of 7 is in effect.

So far, the administrator had to pick one particular cipher which
would then be used throughout all subscribers/phones. This is a bit
impractical, as e.g. not all phones support A5/3. Extend the VTY
command syntax in a backwards-compatible way to permit for multiple
ciphers.
The bit-mask of permitted ciphers from the MSC (sent in ASSIGNMENT
COMMAND) is intersected with the vty-configured mask a the BSC.
Finally, the best (highest) possible cipher is chosen.

There was always a 1:1 correspondence between gsm_subscriber_connection
and osmo_bsc_sccp_con, so there's really no point in having two separate
dynamically allocated data structures with pointers back and forth and
another linked list around.
Let's merge osmo_bsc_sccp_con into gsm_subscriber_connection for
simplicity.
The resulting code might not be elegant in places, but I've tried to
do only the most simple changes in this patch, while further
simplifications can be done in later subsequent patches.
As a side-effect, this patch also fixes lchan clearing if the MSC
(or the local SCCP provider) hard-disconnects the SCCP connection.

Have expicitly named vty write functions for bts and net levels, so that it is
trivial to add commands that exist only on one of each (like the upcoming
congestion check timer config for hodec2).

On BSSMAP Assignment Request received from the MSC, store the Speech Codec List
in the subscr conn, so that we may evaluate available codecs during handover
decision. (Will be used, e.g., by handover_decision_2.)

Separate penalty timers API from specific struct members and move to own .h/.c
file, so that future code may re-use the API arbitrarily.

Upcoming handover_decision_2 will want to be able to handover to a differing
TCH type, hence add a parameter to bsc_handover_start(); adjust current callers
to pass the old lchan type.
Tweak the 'bts' argument to 'new_bts'.

This leaves common_cs.h practically empty. Leave its removal to the next patch,
which removes libcommon-cs entirely
(I07d4a48af3154ee4d904686f230a51b8b8a94ff9).

The gsm_network VTY was partly shared between libmsc and libbsc in the old
openbsc.git; now osmo-bsc.git has its own copy, so merge all of it into
bsc_vty.c.
This leaves common_cs_vty.c practically empty; leave removal of the file to
later, when we drop the entire libcommon-cs in
I07d4a48af3154ee4d904686f230a51b8b8a94ff9.
Note that gsmnet_from_vty() is also already declared in bsc/vty.h.

These functions were originally shared between libmsc and libbsc in the old
openbsc.git; now osmo-bsc.git has its own copies, so move them into libbsc.

Some part of the network init was common between libbsc and libmsc in the old
openbsc.git repository. Now osmo-bsc.git is independent with its own copy of
the gsm_network initialization. So move it over to libbsc.

The separation of gsm_data_shared.* from gsm_data.* historically allowed
compiling parts of it into osmo-bts, which we have dropped since (osmo-bts has
its own copy now). Even though gsm_data.* now becomes rather large by it,
remove the legacy separation to get rid of the "shared" naming, which is no
longer meaningful. A future patch might separate into meaningful smaller bits,
if we get the time.

Replace calls to make_sock() with osmo_sock_init_ofd().
Shame on me for not testing every single one in practice, I hope for peer
review to confirm that this should be correct... Read closely please!
The IPPROTO_GRE define seems to be unused (at least in osmo-bsc.git), drop it
completely.

Provide concise log categories for each main scope.
Move the complete log categories 1:1 to osmo_bsc_main.c.
In bsc_nat.c, omit obviously unused log categories.
In tests, omit almost all log categories, except for those explicitly tested as
the expected output.
Note: should any logging occur for a log category that is omitted by accident,
such will end up being logged as DLGLOBAL, so it will show up and we can fix
it, and it will not get lost silently.

Move bsc_vty_go_parent() to osmo_bsc_main.c and bsc_nat.c, and drop those nodes
that aren't used in the respective main scope.

If a BTS/TRX does not respond to the "IPA RSL Connect" command,
pretend that the BTS has sent a NACK for the connection.
To ensure that osmo_timer_del(&trx->rsl_connection_timeout) is not called
before this timer is initialized with osmo_timer_setup(), the E1 layer now
drops incoming RSL messages from a BTS/TRX in LOCKED administrative state.
We cancel the timeout if we receive an RSL Connect ACK or NACK from the BTS,
and if the underlying E1 link does down.
While here, add a missing message buffer free() in bts_isdn_sign_link().
The callers do not free it.
