A COTS UE is sending UE capabilities with accessStratumRelease "rel16"
which is not decoded by our RRC. Switching to RRC 16.13.0 lets our RRC
accept these capabilities (and as a positive side effect lets this
particular UE work nicely in NSA fr1).
cleanup means:
- typo: susbend -> suspend
- call nr_pdcp_manager_unlock() where needed
- simplify LOG_XX (remove __FILE__, __LINE__, __FUNCTION__)
note:
nr_pdcp_release_srb() and nr_pdcp_release_drb() don't use
nr_pdcp_release_drb() because they modify the arrays, so
it does not make sense to "abstract" the accesses to
->srb and ->drb.
Security part needs to be checked, may fail to work.
But if it fails, it was probably not working before either.
This commit also contains adding 'static' to nr_pdcp_entity_release()
and nr_pdcp_entity_delete() (it was too complicated to do a separate
commit for this).
We also update stats in free_rx_list() (again, too complicated for
a separate commit).
openair2/RRC/NR/rrc_gNB.c probably needs some more work, it is a
bit ugly to reestablish all the drbs without checking if they
exit. It will generate warnings at runtime. I didn't do it because
I don't know the proper way.
The function generateDRB() sets the value to 100ms but the function
rrc_gNB_process_NGAP_PDUSESSION_SETUP_REQ() sets it to 0ms.
So what happens is that the UE gets the value 100ms in the
RRC Reconfiguration but the gNB creates the PDCP entity with 0ms.
Let's create it with 100ms instead, to be aligned with how we configure
the UE.
And also avoid some PDCP warnings at runtime when some packets
are retransmitted but rejected because of the 0ms timer. This is
the warning:
[PDCP] discard NR PDU rcvd_count=68469, entity->rx_deliv 68481,sdu_in_list 0
This is just a hotfix. A real solution is to have the RB creation in
only one place. And we should also have those parameters configurable.
Work for later.
- Reorder the logical channels based on priority
- Handling of configuration and release of logical channel bearer
- Add changes in the implementation of lcp procedure for equal priority logical channels
- Restructure the lcp parameters as a separate structure
- Further code clean up
Closes#685 and #698
