Alexander Couzens 89b4eff243 BSC_Tests: add OML tests for bts_setup_ramp
The current BSC_Tests are using osmo-bts-omldummy to keep OML out of the test context.
Add a new test file and component for OML tests.

This introduces the Lb interface stack, which allows BSC_Tests.ttcn
to emulate a SMLC towards the BSC.

In accordance with

Harald Welte 8cb5825ffc Revert "bsc: Add Lb interface support"
This reverts commit c47fdb2e52 - as
osmo-bsc currently doesn't yet have a Lb interface, we shouldn't try
to test it yet.

Pau Espin e8d7d16f13 Split templates in RLCMAC_{CSN1_}Types into their own _Templates file
RLCMAC blocks have a lot of fields and we will potentially require lots
of different templates, as well as functions to handle related structs.

Harald Welte 09538f8bfd bsc: Test suite for CBSP (Cell Broadcast Service Protocol)
In this testsuite, we simulate BTS and CBC by attaching to RSL and CBSP
protocol interfaces of the BSC.  We then issue a variety of CBSP
commands to the BSC and check for corresponding action on both the BTS-
facing RSL as well as responses on the CBSP side.

Pau Espin fe0c6083bd Depend on our own fork of titan.ProtocolModules.BSSMAP
Since we use some BSSMAP extensions to signal Osmux, we need to maintain
our own fork of BSSMAP_Types in order to supports those IEs in BSSMAP
RESET and BSSMAP Assin Req/Compl. Hence, switch all build componenets to
fetch and use our fork.

Harald Welte 2fce7887f4 RAN_Emulation: Modularize protocol support
The RAN_Emulation currently unconditionally provides BSSAP and MGCP support.
Let's re-structure the code so that support for those protocols is now
possible to enable/disable at compile time.

This patch is in preparation of introducing RANAP support in RAN_Emulation.

Harald Welte 6811d10af7 Rename BSSMAP_Emulation -> RAN_Emulation
So far, BSSMAP_Emulation supported only a transport over BSSMAP.
However, we soon intend to merge support for RANAP in order to
simulate RANAP/Iu connections as well as BSSMAP.  Let's start
by renaming some of the existing types/functions/ports/modules
without introducing any functional changes just yet.

Daniel Willmann d93047434b Add Misc_Helpers.ttcn to centralize TTCN3 shutdown handling
This function can now be called from anywhere to try and safely shutdown
a testcase. It is not optimal as we can't call "all component.stop" from
outside the mtc, but without any proper and orderly shutdown handling of
all our emulation components I believe this is the best we can do.

To use it:

import from Misc_Helpers all;

in your module and then call

Misc_Helpers.f_shutdown(__BFILE__, __LINE__);

You can also pass the function a verdict and a message and it will take care
of calling setverdict, but beware of the following:

While setverdict would accept any number of arguments as log message
and convert them to a log string f_shutdown expects one charstring.
It's possible to use the log2str function to use the log arguments in
setverdict for f_shutdown, for example

setverdict(fail, "Template didn't match: ", tmpl_foo);
would become
Misc_Helpers.f_shutdown(__BFILE__, __LINE__, fail, log2str("Template didn't match: ", tmpl_foo));

Stefan Sperling 0796a82c86 Add a TTCN3 module for IPA protocol testing
This new module allows us to test IPA code in libosmocore
and libosmo-netif. Currently only one test is implemented,
which sends a chopped IPA ping message and expects to receive
an IPA pong.

The system under test is any IPA speaker on any TCP port.
Any test suite may call parametrized functions to create
an IPA testing component and run a particular test.
So far, one such test has been added to the BSC_Tests suite.

Stefan Sperling c307e689b4 introduce a TTCN3 test suite for SCCP
This test suite acts as an SCCP server on top of M3UA.

SCCP tests are run against the sccp_demo_user program which
can be found in libosmo-sccp/examples. This program must be
started in client mode: sccp_demo_user -c
The SCCP test suite should then work out of the box with
the provided SCCP_Tests.cfg file and this additional change
to sccp_demo_user default point codes:

There is currently only one test, for the libosmo-sccp crash
reported as issue OS#2666. The implementation of this test
is currently using an ugly workaround due to shortcomings of
the M3UA Emulation layer (see source code comments). Whether
a better solution is feasible is still to be determined.

The test requires a patch to the SCCP Protocol Emulation which
has been submitted upstream:

However, it has been for many months, so let's remove our local copy
and use upstream git repositories like for all the other modules.

of gen_links():

- At the top of, clear the .gitignore.
- In the loop, add each link name to the local .gitignore.
- In selected, there is also a "manual" link creationg. So that
  this also ends up in the local .gitignore, have the link creation as separate
  gen_link() macro which at the same time adds to ./.gitignore.
- in the root .gitignore, ignore all the subdirs' generated */.gitignore files.

Harald Welte df277258f1 IPA_Emulation: Make dependencies to RSL/MGCP/SCCP/GSUP conditional
Let's use the preprocessor to avoid IPA_Emulation pulling *all*
dependencies into each and any of our projects.  The code readability
suffers a bit from the many #ifdefs, but compilation speed increases
if we don't have to pull in all those (recursive) dependencies.

After all, a BTS test case will never need SCCP, GSUP or MGCP.

Harald Welte 624f963393 BSC_Tests: Prepare for tests based on {RSL,BSSMAP}_Emulation
The existing tests were implemented directly on top of the BSSMAP
and RSL CodecPorts.  If we loop in the RSL_Emulation and
BSSMAP_Emulation components, we can properly multiplex/demultiplex
multiple MS (radio channels) on both the RSL and the MSC (SCCP
connection) side.

In order to have a single component that handles both the RSL and the
BSSAP side of a given channel/subscriber/call, we introduce the concept
of BSSMAP "Expects", where the test csse can register the L3 INFO that
it sends in the RLL ESTablish INDication on the RSL side, so the BSSMAP
handler cna route the BSC-originated SCCP connection with that L3 INFO
back to the same component.  This is a bit inspired "in spirit" of the
"expect" mechanism of netfilter connection tracking.

This commit changes the system to make sure we clone all git repos
we depend upon into the 'deps' folder, and then setup the symlinks
to that folder.  As a result, we should be able to support
self-contained builds using the makefiles in this repo.

messages back and forth for low-level testing such as timeouts, response
