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.

RELEASE NOTES:
v0.1 -> Last stable commit on develop branch before enhancement-10-harmony
v0.2 -> Merge of enhancement-10-harmony to include NGFI RRH + New Interface for RF/BBU
v0.3 -> Last stable commit on develop branch before the merge of feature-131-new-license. This is the last commit with GPL License
v0.4 -> Merge of feature-131-new-license. It closes issue#131 and changes the license to OAI Public License V1.0
v0.5 -> Merge of enhancement-10-harmony-lts. It includes fixes for Ubuntu 16.04 support
v0.5.1 -> Merge of bugfix-137-uplink-fixes. It includes stablity fixes for eNB
v0.5.2 -> Last version with old code for oaisim (abstraction mode works)
v0.6 -> RRH functionality, UE greatly improved, better TDD support,
a lot of bugs fixed. WARNING: oaisim in PHY abstraction mode does not
work, you need to use v0.5.2 for that.
v0.6.1 -> Mostly bugfixes. This is the last version without NFAPI.
v1.0.0 -> January 2019. This version first implements the architectural split described in doc/oai_lte_enb_func_split_arch.png picture.
Only FAPI, nFAPI and IF4.5 interfaces are implemented.
Repository tree structure prepares future integrations of features such as LTE-M, nbIOT or 5G-NR.
Preliminary X2 support has been implemented.
S1-flex has been introduced.
New tools: config library, telnet server, ...
A lot of bugfixes and a proper automated Continuous Integration process validates contributions.
v1.0.1 -> February 2019: Bug fix for the UE L1 simulator.
v1.0.2 -> February 2019: Full OAI support for 3.13.1 UHD
