Harald Welte d1209a6f04 Move "connect to L1CTL and RESET" function from LAPDm_RAW_PT to L1CTL_PortType 2017-07-29 12:55:06 +02:00
Harald Welte 484160bf21 library: Initial work on GPRS RLC/MAC encoder/decoder 
For Downlink and Uplink RLC/MAC Control blocks this is already working
quite nicely.  Data blocks is not working, as their encoding cannot be
expressed in TTCN-3 RAW syntax, and a mixture of C++/native and
RAW-generated coder will be required.

Harald Welte 6e594f217a gprs_gb: Build stack of NS and BSSGP emulation from test component 
We're already getting the NS link up and fail at the BSSGP RESET
procedure at this point.  The problem is erroneous encoding of the
message.

Harald Welte 599faa1d18 Add LAPDm test case about SABM contention 2017-07-17 21:49:24 +02:00
Harald Welte dca7e45ce8 don't match on L1CTL SAPI in received frames 
L1 has no idea about the SAPI encoded in LAPDm when it passes a
PH-DATA.ind up to us.  So dont match on that L1CTL field, only match the
SAPI we decoded from LAPDm header.
 2017-07-17 21:43:58 +02:00
Harald Welte d4ba7ff93e Add new LAPDm RAW port 
This is a Test Component which sits on top of L1CTL (which in turn is on
top of the Unix Domain Socket Test Porrt).  It performs LAPDm message
encoding/decoding, so we can use the regular send() / receive() methods
and associated template matching to send/receive/match LAPDm in a
comfortable way.

Harald Welte cb5d1fb2ee fix ts_RslLinkID_SACCH template 2017-07-17 21:00:15 +02:00
Harald Welte 1bd7c32db8 export more encoder/decoder functions for LAPDm RAW coder debuggin 2017-07-17 20:59:46 +02:00
Harald Welte c2a5c07267 LAPDm_Types: re-order fields of LapdmCtrl definitions 
for some reason, the "TAG()" matic of TITAN RAW decoder seems to fail
when we use FIELDORDER(msb) and match on a field that's not the first
field of the sub-record :/

Re-ordering the fields into LSB order seems to resolve this.

Harald Welte 143edbd5e9 L1CTL_Types: Fix copy+paste error in t_L1CTL_DM_REL_REQ 
t_L1CTL_DM_REL_REQ shouldn't generate an DM_EST_REQ !
 2017-07-17 20:56:56 +02:00
Harald Welte 9e4725dcd3 l1ctl/lapdm test infrastructure: Move helper functions out 
moving all templates into L1CTL_Types as well as helper functions into
L1CTL_PortType allows us to have a clean L1CTL_Test.ttcn where we can
focus on actual test cases.  At the moment it's just a PoC that can
establish dedicated mode and send a SABM frame to the BTS, which is
properly echo'ed back in the UA, as expected for contention resolution.

Harald Welte 66110f0d77 L1CTL Test: Get all the way up to dedicated channel establishment 
The code is now a proof of concept to establish a dedicated channel
via virt_um, at which point we can exchange L2 messages with the BTS.

Harald Welte 52c713c452 Implement L1CTL port type (dual-faced port on top of UnixDomain) 2017-07-16 15:44:44 +02:00
Harald Welte f654332701 first steps towards a L1CTL / LAPD test 
The idea here is to implement the L1CTL protocol in TTCN-3 so we can
speak it over a unix domain socket (test port) for simple tasks such as
activating dedicated mode.

This can then subsequently be used for LAPDm testing
