Moved to doc/manuals/, with full commit history, in preceding merge commit.
Now incorporate in local the build system.
Build with:
$ autoreconf -fi
$ ./configure --enable-manuals
$ make
Shared files from osmo-gsm-manuals.git are found automatically if
- the repository is checked out in ../osmo-gsm-manuals; or
- if it osmo-gsm-manuals was installed with "make install"; or
- OSMO_GSM_MANUALS_DIR is set.

At the moment there are three sources that may advertise a list of
supported audio codec/rate settings. There is the MS that advertises
advertises a speech codec list and the MSC that sends a channel type
information element over A and there are also settings in the bsc
configuration file that may restrict the codec/rate types that are
allowed to use.
The function match_codec_pref() looks at all of the three buckets and
selects a codec that satisfies all three. This is already a somewhat
complicated process, overit is very isolated, so lets give it its own
c-file.
Due to the lack of unit-tests it is very hard to make changes here so
lets add also unit-test to make sure that regressions are catched early.
- Put match_codec_pref() and all its helper functions into a separate
c-file.
- Add a unit test.

Move all of libbsc/ into osmo-bsc/, and separate/move some implementations to
allow linking from utils/* and ipaccess/* without pulling in unccessary
dependencies.
Some utilities use gsm_network and gsm_bts structs, which already include data
structures for fairly advanced uses. Move initialization that only osmo-bsc
needs into new bsc_network_init() and bsc_bts_alloc_register() functions, so
that the leaner tools can use the old gsm_* versions without the need to link
everything (e.g. handover and lchan alloc code).
In some instances, there need to be stubs if to cut off linking "just before
the RSL level" and prevent dependencies from creeping in.
- abis_rsl_rcvmsg(): the only program currently interpreting RSL messages is
osmo-bsc, the utils are merely concerned with OML, if at all.
- paging_flush_bts(): ip.access nanobts models call this when the RSL link is
dropped. Only osmo-bsc actually needs to do anything there.
- on_gsm_ts_init(): the mechanism to trigger timeslot initialization is related
to OML, while this action to take on init would pull in RSL dependencies.
utils/ and ipaccess/ each have a stubs.c file to implement these stubs. Tests
implement stubs inline where required.
From src/utils/, src/ipaccess/ and tests/*/, link in .o files from osmo-bsc/.
In order for this to work, the osmo-bsc subdir must be built before the other
source trees. (An alternative would be to include the .c files as sources, but
that would re-compile them in every source tree. Not a large burden really, but
unless linking .o files gives problems, let's have the quicker build.)
Minor obvious cleanups creep in with this patch, I will not bother to name them
individually now unless code review asks me to.
Rationale:
1) libbsc has been separate to use it for osmo-nitb and osmo-bsc in the old
openbsc.git. This is no longer required, and spreading over libbsc and osmo-bsc
is distracting.
2) Recently, ridiculous linking requirements have made adding new functions
cumbersome, because libbsc has started depending on osmo-bsc/*.c
implementations: on gscon FSM and bssap functions. For example, neither
bs11_config nor ipaccess-config nor bts_test need handover_cfg or BSSMAP
message composition. It makes no sense to link the entire osmo-bsc to it, nor
do we want to keep adding stubs to each linking realm.

Rationale: channel_test is trivial and useless, probably only exists as a
legacy from openbsc.git.
- it tests two printf()s of "(bts=45,trx=0,ts=3,ss=4)", hardly useful.
- it tests ts_subslots() behavior for dyn ts, which will soon be replaced by a
most trivial mapping that does no longer need complex dyn ts state
evaluation (when introducing the new timeslot FSM to handle dyn TS switchover).

Rationale:
- All it does is compose four Paging Requests and feed it into the osmo-bsc
bssap_udt, and expects the cell identifier to be decoded properly.
- To do so it employs a comparatively huge linking effort. This linking effort
is becoming annoying in my ongoing work and is just not worth it.
- We have comprehensive cell identifier tests in ttcn3, verifying that the
proper cells are paged, and that actually for *all* cell identifier types.

osmo-bsc_nat is too heavily tied into legacy SCCPlite code, as it
is not using libosmo-sigtran/osmo_ss7 so far. It's also full of
customer-specific code and it's shared use of some libbsc code here
has been complicating osmo-bsc development.
The current plan is to continue to use osmo-bsc_nat from openbsc.git
for those legacy users that need it, and not use osmo-bsc_nat in
new 3GPP AoIP setups. Should we ever get a strong demand for an AoIP
based bsc_nat, we can still revisit this later.

Provide a sane means of adding the -Werror compiler flag.
Currently, some of our jenkins.sh add -Werror by passing 'CFLAGS="-Werror"',
but that actually *overwrites* all the other CFLAGS we might want to have set.
Maintain these exceptions from -Werror:
a) deprecation (allow upstream to mark deprecation without breaking builds);
b) "#warning" pragmas (allow to remind ourselves of errors without breaking
builds)
As a last configure step before generating the output files, print the complete
CFLAGS and CPPFLAGS by means of AC_MSG_RESULT.

The ipa.py has been moved to osmo-python-tests as osmo_ipa - use it for

are not BSC-specific: leftovers from repository split which are now

According to documentation (and personal experience), AM_PATH_PYTHON
selects the highest version of python, no matter if major version is
different, which means if both python2 and 3 are available, 3 will be
chosen an PYTHON will point to "/.../python" which is python3. Apparently,
the macro cannot be easily used to pick highest python2 version.
As {vty,ctrl}_test_runner.py require python2 and are incompatible with
python3, let's instead rely on the system having a "python2" binary
available, which is the case in most distros.

osmo-bsc currently negotiates the RTP stream directly with the
BTS and reports back the RTP IP/Port on the BTS. This works fine
for a single BTS, but for Handover the port/ip pointing to the
MSC side must not change, so an entity in between the BTSs and
the MSC is required.
Integrate the mgcp-client and use osmo-mgw to switch the RTP
streams.

3GPP TS § 08.08 defines various types of Cell Identifier List IEs, but we only
implement "entire BSS" and "one LAC". If the MSC sends a Cell Identifier List
that we don't implement, it is best for interoperability to page the entire BSS
and post a log message instead of rejecting the paging altogether. Apart from
resource management, it is not harmful to page more than the MSC requested; if
use of resources becomes an issue, the log message will guide towards the
solution of providing an actually implemented Cell Identifier List IE.
Upon IE length that is other than we expect, log the error, but also fall back
to paging the entire BSS. Overall message length correctness has been checked
earlier.
The particular case observed is that a Huwaei MSC sends a LAI for Cell
Identifier List (MCC+MNC in bcd, followed by a LAC), parsing of which we may
want to add later.
Improve logging: identify the subscriber that is being paged.
Coding style: use a switch() statement to clarify flow and provide a place to
add more implementations later.
Add regression test bssap_test.c: fabricates BSSAP Paging messages with the two
implemented Cell Identifier List IEs as well as the unimplemented LAI
identifier, verify the resulting paging LAC in wrapped function and stderr.

This is the OsmoBSC project. Disabling the build of the BSC would be
somewhat odd, so let's remove the option.
Also, OsmoBSC depends on libosmo-sccp now, so we must unconditionally
depend on it. As a result, we can remove the --enable-nat option,
as this was only to avoid a mandatory libosmo-sccp requirement in
historical times.

This was originally a long series of commits converging to the final result
seen in this patch. It does not make much sense to review the smaller steps'
trial and error, we need to review this entire change as a whole.
Implement AoIP in osmo-msc and osmo-bsc.
Change over to the new libosmo-sigtran API with support for proper
SCCP/M3UA/SCTP stacking, as mandated by 3GPP specifications for the IuCS and
IuPS interfaces.
From here on, a separate osmo-stp process is required for SCCP routing between
OsmoBSC / OsmoHNBGW <-> OsmoMSC / OsmoSGSN
jenkins.sh: build from libosmo-sccp and osmo-iuh master branches now for new
M3UA SIGTRAN.

Original libvlr code is by Harald Welte <laforge@gnumonks.org>,
polished and tweaked by Neels Hofmeyr <nhofmeyr@sysmocom.de>.
This is a long series of trial-and-error development collapsed in one patch.
This may be split in smaller commits if reviewers prefer that. If we can keep
it as one, we have saved ourselves the additional separation work.
SMS:
The SQL based lookup of SMS for attached subscribers no longer works since the
SQL database no longer has the subscriber data. Replace with a round-robin on
the SMS recipient MSISDNs paired with a VLR subscriber RAM lookup whether the
subscriber is currently attached.
If there are many SMS for not-attached subscribers in the SMS database, this
will become inefficient: a DB hit returns a pending SMS, the RAM lookup will
reveal that the subscriber is not attached, after which the DB is hit for the
next SMS. It would become more efficient e.g. by having an MSISDN based hash
list for the VLR subscribers and by marking non-attached SMS recipients in the
SMS database so that they can be excluded with the SQL query already.
There is a sanity limit to do at most 100 db hits per attempt to find a pending
SMS. So if there are more than 100 stored SMS waiting for their recipients to
actually attach to the MSC, it may take more than one SMS queue trigger to
deliver SMS for subscribers that are actually attached.
This is not very beautiful, but is merely intended to carry us over to a time
when we have a proper separate SMSC entity.
Introduce gsm_subscriber_connection ref-counting in libmsc.
Remove/Disable VTY and CTRL commands to create subscribers, which is now a task
of the OsmoHLR. Adjust the python tests accordingly.
Remove VTY cmd subscriber-keep-in-ram.
Use OSMO_GSUP_PORT = 4222 instead of 2222. See
