Francisco Paisana 37ce475398 fix+refactor of the ue rrc handover preparation procedure to avoid deadlocking 5 years ago
Pedro Alvarez 960c0e97cd Added handling of RRC re-establishment to srsENB. 
* Added the appropriate code for handling and sending the
   re-establishment procedure messages to rrc_ue.c/.h.
 * Triggered RRC reconfiguration after the reception of RRC
   re-establishment complete
 * Refreshed K_eNB at the reception of re-establishment
   request
 * Changed the mapping of TEIDs to RNTIs in the GTP-U layer,
   as the RNTI might change with reestablishment.

chaolinyi bbe25a00d4 Update proc_ra.cc to bugfix RA-RNTI calculation 
Bugfix the wrong ra_rnti calculation in ra_proc::state_pdcch_setup.
According to TS 36.321 Subsection 5.1.4 Random Access Response reception, we can see the formula on RA-RNTI, which is,
    RA-RNTI= 1 + t_id + 10*f_id,
where t_id is the index of the first subframe of the specified PRACH (0≤ t_id <10), and f_id is the index of the specified PRACH within that subframe, in ascending order of frequency domain (0≤ f_id< 6). Then, reading the srslte source code, we can see that, the code should bugfix. 
BTW, the wrong code can run normal for LTE_FDD, causing of the info_f_id = 0; but it should be wrong, when it is LTE_TDD.

Andre Puschmann 25ab36ddd5 nas: fix UE not attaching if PLMN isn't found after switching on 
if no cell/PLMN can be found if the UE is switched on, the UE was never
trying again.
In theory this would be handled by T3410, but the timer
is not started in case the PLMN search isn't done yet.

Andre Puschmann a4abd96ab6 nas: use MME security header when receiving identity request

identity response to a plain identity request

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.

Andre Puschmann 62e4bd9469 log_ptr: fix issue if accessing log_ptr that was reset already 
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

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.
