Andre Puschmann d0480141e5 nas: move re-arming and stopping of attach request related timers
t3402, t3410 and t3411 are now managed in the sender
function of the attach request. previosly they were only
correctly started in the high-level NAS call start_attach_request()
which may not be called if NAS itself resends the request

Francisco Paisana 8e837e173d printf has already a way to pad spaces. If we use it, we can avoid accidentally adding extra logs because we did srslte::logmap::get("MAC") instead of srslte::logmap::get("MAC ") 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 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 8d284f48bd cancel RA when receiving contention resolution in wrong state
this fixes a bug in which the contention resolution timer expired
and the RA proc entered the BACKOFF state.
In the same TTI, a MAC PDU with the contention reslution ID is received
and the already aborted RA procedure succeeds. Unfortunatly with the
wront c-rnti which has already been reset before. See log excerpt

Xavier Arteaga 4d3c28ff97 SRSUE: wait for valid RSRP measurement before adquiring SIBs during cell search 5 years ago
Andre Puschmann 2a46413121 during cell search don't configure found cell as serving cell
this fixes an issue in which, during cell search, the sync code
itself would set the serving cell whenever it found a new cell.

instead, only report the found cell to RRC and keep the sample
rate at 1.92 MHz. RRC may select a new serving cell and then tell
PHY to camp on it.

Andre Puschmann 6ec573987a remove default value for 'blocking' param from pdcp::write_sdu()
there were two defaults and one was shadowing the other. This
commit removes both defaults and uses blocking-mode for RRC
calls to PDCP in the UE. The eNB write_sdu() uses the non-blocking
mode by default. We have to review the eNB's RRC perhaps and use blocking
there too and non-blocking only for data plane
