Alexander Couzens e0f7c543b7 NS_Emulation: remove dependency on PCUIF_Types
The dependency of PCUIF_Types creates also a dependency on

Replace the PCU_AddrType by an unix like address family defined
in the Osmocom_Types to reduce the dependency.

Harald Welte 60408e3f57 Don't map NS_Emulation_CT:NSCP anymore
NS_Emulation_CT:NSCP used to be a NS_CODEC_PT, which is a translation
port on top of the IPL4asp.  Such ports need to be mapped to a system
port at start-up.

However, in I4d0b7ad0ed9447a038dd3eeee2b975146d10fba0 we introduced
a new underlying component called NS_Provider.  Hence, NSCP is actually
connected to that underlying component, and no longer mapped.

The corresponding change in pcu/SGSN_Components.ttcn and sgsn/SGSN_Tests.ttcn
has unfortunately been missed in the above-mentioned change.  Fix that.

Harald Welte 557c9f8cb8 move some key types from GSM_RR_Types to GSM_Types
This in turn means Osmocom_Gb_Types doesn't need to depend on
GSM_RR_Types anymore, which is particularly ugly as the latter
now depends on RLCMAC_*, creating a long chain of dependencies.

So far, the ConnHdlr components were only able to exchange BSSGP PDUs

actually connect to the BSSGP_SP_SIG that BSSGP_Emulation provides.

Daniel Willmann 1c1161119d SGSN_Tests: Wait for RAU Accept after receiving SecurityModeCmd
We don't want to pass the test or return from this function before
receiving a RAU accept. With Iu we expect a Security Mode
Command/Complete before the routing area is updated, but we do want to
wait for the actual RAU Accept or fail when receiving a RAU Reject.

Pau Espin ce571b5cc4 sgsn: Introduce test TC_attach_req_id_req_ra_update
The scenario in this test triggers a crash in osmo-sgsn fixed by
osmo-sgsn.git I64fa5cf1b427d3abb99e553e584897261a827ce6.

With that osmo-sgsn patch applied, the process doesn't crash anymore but
the test still fails due to an XID message being sent with a new
yet-not-seen-by-ttcn3 TLLI and as a result TTCN3 BSSGP_Emulation fails:
BSSGP_Emulation.ttcn:390 setverdict(fail): none -> fail reason: "Couldn't find Component for TLLI 'FE791757'O", new component reason: "Couldn't find Component for TLLI 'FE791757'O"

Other than that, the test runs fine. It still needs to be clarified
whether the new TLLI sent by osmo-sgsn is expected and test needs to be
fixed, or whether it's an sgsn bug.

Alexander Couzens 42d3cadb05 sgsn: delay f_gmm_attach() by 50ms
Packets sent by f_gmm_attach() might take too long via layers to reach
the SGSN. The GMM_ATTACH_COMPL in f_gmm_attach() took soo long,
that it arrived after packets, which has been sent after calling f_gmm_attach().
This behaviour was found in TC hlr_location_cancel_request_update().

Oliver Smith aac9b9ceca BSSGP_Emulation: add BssgpDecodeDepth
Make the decoding level (BSSGP, LLC, SNDCP, L3) configurable, so the
existing PCU tests, that expect messages only decoded to the BSSGP
level, can pass again. Move the SNDCP decoding in f_dec_bssgp above the
L3 decoding, so f_dec_bssgp goes through the layers in the reverse order
of f_send_bssgp_dec.

I have verified, that all testsuites using the BSSGP Emulation (SGSN,
PCU, PCU-SNS) are still working with this patch.

Harald Welte 955aa94504 BSSGP_Emulation: Abandon "BssgpDecoded" intermediate structure
It originally seemed like a great idea to define a custom record
which aggregates the decoded BSSGP, LLC, L3 and/or SNDCP and passes
it to the individual ConnHdlr.  However, particularly with testcase
interoperability for IuPS in mind, this seems bogus.  Also, we
never really took advantage of this.

Let's now decode as far as we can decode any PDU, and then send the
decoded version of that PDU via the ports between the BSSGP_Emulation
and the ConnHdlr component.
