Andre Puschmann acc2948b45 nas: fix security handling
First of all, with this the NAS conformance tests pass with ciphering and
integrity turned on. Before only integrity was working.

Mainly the NAS was applying the integrity protection and/or ciphering
incorrectly because it wasn't taking the secuirty status of the PDUs
into account. Some where already correct, some not. The patch
streamlines the handling for all outgoing messages.

during deinit of the UE/eNB it could happen that the log_ptr
was already set to null but the stack thread was still accessing
it through log_h->info()

i've moved the old macro into a new header and used as as much
as possible. there are still places in the code where similar
macros are used but we would need to change the variable name
to replace them

Daniel Willmann 3a804e23fa ttcn3_sys_interface: Parse SIBs even when "StaticCellInfo" is missing
The test TC_9_2_1_1_1 sends a Cell->AddOrReconfigure->Basic message
without a "StaticCellInfo" member. This is used to change SIB1 of
the cell and simulate a different PLMN/TAC in the test.

handle_request_cell_basic() ignored the json message if "StaticCellInfo"
is missing which results in the SIB not being updated (PLMN stays as
00102 for example).
With this patch the SIBs after the json are now parsed even if there
"StaticCellInfo" is missing. A confirmation of the json is not sent
because the test does not seem to expect one in that case.

Andre Puschmann e7c10270fa ttcn3_ss: fix security activation for PDCP 2020-03-01 18:26:45 +01:00
Andre Puschmann 9e113f8b27 pdcp: allow to configure security for rx/tx seperately
previously PDCP security (integrity and ciphering) could only
be enabled for both Rx and Tx at the same time.

this, however, caused an issue during the conformance testing in which,
in TC_8_2_1_1() for example, the eNB sends a SecModeCommand and a
RRC Reconfiguration in the same MAC TB. In this case, the eNB
needs to be able to enable DL security right after sending the SecModeCmd
in order to send the RRCReconfig encrypted. However, enabling UL security needs
to be postponed until after the SecModeComplete is received.

This patch allows to enable PDCP security for rx/tx independently if
that is needed. The default way is like before, enabling it for tx/rx at
the same time.

Andre Puschmann 81e28aa9dc add basic support for TimingInfo field from tester
this fixes an issue where commands are received out of
order and we are therefore applying configs incorrectly. if
commands include a timinginfo we are now putting the command
on a queue that the SS reads after the start of a new TTI.

the security and cell reconfig commands will be added in another
PR after the AS_security command has been fixed.
