With the introduction of X2AP into develop, the UEs now have to regularly
send measurement reports.
In the logs of the eNB, we see:
[OSA] Mismatch found in integrity for algorithm 2,
got e0.a0.c2.66, expecting a5.9c.cb.57
[PDCP] [OSA][RB 1] eNB failed to validate MAC-I of incoming PDU
This is a bug in the PDCP layer that uses wrong parameters to compute the
integrity.
This commit fixes this bug.
The function pdcp_is_rx_seq_number_valid was removed. Its processing
has been directly integrated into the function pdcp_data_ind.
The function pdcp_mark_current_pdu_as_received is not called anymore.
Its processing was not used later on, so as of today, not calling it does
not introduce any functional change.
The function pdcp_validate_security takes now as parameters both
SN and HFN. Same for the function pdcp_get_next_count_rx.
Useless constants PDCP_SN_5BIT, PDCP_SN_7BIT and PDCP_SN_12BIT have been
removed.
The compilation option ENABLE_SECURITY has been removed. It's now always
on. (This may impact some use cases.)
The PDCP for DRB using RLC AM is not correct. It was not correct before
this commit (apart from the integrity bug). We should deal with a list
of PDUs and transmit packets to upper layers as detailed in the specs.
Today we transmit the PDU as soon as we get it. We don't care about
duplicates, in-order delivery, timeouts.
Also, we don't deal with "PDCP re-establishment". Not sure how that impacts
the software.
And, last but not least, there is still no ROHC.
* Add VCD timing for PDCP, RLC, and MAC
* Update MAC-PHY interface
* update eNB MAC DLSCH scheduler and preprocessor with component carrier
* Add test case for dlsim performance

With folowwing implicit rule
drb id = x => correspondind lc id = x+2, eps bearer id = x+4
Changed RLC inner structs, no more statically allocated array, now it is dynamic via malloc and collection of RLC entities are stored in a hashtable.
Changed misc simple types
Started compiling with all warning setted and treated as errors, still working on RLC and around...
Add const qualifier wherever suitable (for example param frame, module id, const pointers, etc)
Thinking about a type of context parameter in procedure calls in L2 data plane (modules id, frame, srb flag, enb flag, etc)...

- Output logs from ping/oaisim in two distincts files
- Fix some compiler warnings
- Put assertions in some switch default cases
- Create a wrapper for macphy_exit to display FILE and LINE of the caller
- Enabled -Werror=implicit-function-declaration

- Created Makefile.common that gathers common definitions for oaisim and lte-softmodem
- Added ITTI capabilities to lte-softmodem (currently not stable)
* Created dummy l2l1 task
* Added -K option to output itti messages to file (some RT issues with file flush)
- Added S1AP/SCTP tasks in lte-softmodem
pre-ci ok
lte-softmodem with HARD_RT=1 build ok
