Neels Hofmeyr b2b3704d2a BSSAP_LE_Emulation: configure sending vs receiving RESET
Expecting OsmoBSC to send a RESET to the SMLC implies that the virtual SMLC
stays quiet until a RESET is received. Add flag to configure RESET behavior of
BSSMAP-LE.

Harald Welte e97e3af203 PCU_Tests_{NS,SNS}: Fix our expectations regarding CellID in BVC-RESET
The BVC-RESET / BVC-RESEt-ACK follow a set of rules:

* Signaling BVCI=0 never has a CellId in BVC-RESET nor BVC-RESET-ACK
* Any BVC-RESET or BVC-RESET ack in BSS->SGSN direction must have CellID
* Any BVC-RESET or BVC-RESET ack in SGSN->BSS direction must NOT have CellID

Let's adjust our test expectations accordingly.

This will break tests against "latest", but the amount of work-arounds
needed in this code outweighs the benefit.

Harald Welte 5339b2e372 BSSGP_Emulation: Support multiple PTP-BVC within one Entity
The existing BSSGP_Emulation is built around the assumption that every
instance of BSSGP_Emulation only servers one signaling-BVC and one
PTP-BVC.  While this is true for osmo-pcu at this point (BTS-colocated
PCU), other BSS/PCU implementations differ.

In general, there can always be any number of PTP BVC (one per cell)
next to the signaling BVC (one per BSS).  Let's represent this in
BSSGP_Emulation so we can create more comprehensive tests.

Vadim Yanitskiy 220fa204da fixup library/PCUIF_Types: version 10: do not add redundant padding
Unlike osmo-pcu, osmo-bts does check length of the messages received
over the PCU interface, so I7a532d7abff8af354e40c5d706bb882efc6f905f
caused all the related test cases in ttcn3-bts-test to fail.

Reverting it is not a solution, because we cannot maintain different
padding attributes for two different protocol versions.  Let's add
a wrapper function that would call enc_PCUIF_Message() and append
padding depending on the configured protocol version.  In addition,
let's add a module parameter that would allow us to (optionally)
disable padding for ttcn3-pcu-test.

This change makes all broken PCUIF specific test cases pass.

Vadim Yanitskiy 43ccaf51f2 library/PCUIF_Types: version 10: add Mobile Allocation length field
My initial assumption was that we can skip redundant '0'B bits or
even '00'O octets in the Mobile Allocation IE, and thus reduce
the overall size of this element.  Unfortunately, this is wrong.

3GPP TS 44.018, section 10.5.2.21 clearly states that the Mobile
Allocation IE contains a bit-string of size NF, where NF is the
number of frequencies in the cell allocation.  If NF % 8 != 0,
then '0'B padding bits must be appended to make it octet-aligned.

In other words, if the cell allocation contains let's say 13
frequencies, but a hopping timeslot makes use of only a small
fraction of it (e.g. 4 first channels), we would still need to
transmit at least 13 bits (+padding), including all redundant
bits and octets.

In RLC/MAC frames though it's not required to make the bit-string
octet aligned, so we need to send exactly NF bits without padding.

In order to achieve that:

  a) add MA length field to INFO.ind (record PCUIF_InfoTrxTs);
  b) ajust the existing test cases to use this field.

It's safe to merge this change as the related patches have not
been merged to osmo-pcu and osmo-bts yet.
