Andre Puschmann dbb8b6a360 nas: add helper for entering new state in FSM

Andre Puschmann f477c1d2e5 nas: allow starting a attach request procedure even if a PLMN is already selected
previously the NAS would cancel a attach request procedure if the PLMN
is already selected. PLMN selection, however, in not necessarily happening
before requesting RRC to establish a connection.

Andre Puschmann 94c6034339 nas: rename start_attach_request to start_attach_proc
this is to better differentiate from "send_attach_request" that
only packs and send the actual attach request message. The
entire attach procedure may include PLMN search, etc.

correctly started in the high-level NAS call start_attach_request()

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 5 years ago
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

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

Andre Puschmann dc4be1b856 fix overwriting dedicated_info_nas in connection_request_proc
this fixes an issue in the step() function of the connection_request_proc
in which the dedicated_info_nas message was passed to RRC without
checking if its actually valid or not, i.e. contains a message at all.

because this check was missing and the step() function could be called
multiple-times, the function would overwrite the dedicated_info_nas
in RRC, and therefore causing the connection setup complete to fail

Andre Puschmann c7343cf6d8 protect sf_buffer from overrun in receive_samples
this patch adds a buffer len paramter to the receive_samples() call
that protects the (also) provided buffer from overflowing.

currently each call to srslte_ue_sync_zerocopy() which then calls receive_samples()
relies on a buffer that is "big enough". But that buffer is sometimes
2 subframes, sometimes 3 or 5, sometimes has space for the maximum PRB size, sometimes
only for 6 PRBs (i.e. during cell search).

By extending the interface to pass the buffer size we can make sure that
only samples are received that actually fit inside the provided buffer.

Pau Espin Pedrol 4949df257e Proper shutdown on SIGHUP
If a process exits and has a controlling terminal, everything under
it gets a SIGHUP by the kernel. That's the case for instance when
running a srsUE over ssh with some specific parameters. As a result,
when the ssh client is killed, SIGHUP is sent to srsUE, which will be
killed immediatelly without proper release, which means in turn that log
buffers are not flushed.
Let's do proper shutdown when SIGHUP is received so that everyone can
get log files.
