Andre Puschmann 0a16f48869 gw: fix race condition 
GW thread was checking the default_eps_bearer variable without
protection. RRC could update it when deleting DRB or receiving RRC
connection release.
 2021-06-28 17:35:02 +02:00
Andre Puschmann 368c7b9e4f ue,stack: clear all EPS bearers when going RRC idle 
the EPS bearer manager was only informed when a single DRB
was removed but not when entering idle which requires to
remove all bearers.

This cause the service request to fail.

Andre Puschmann 5313fb99d6 tft: add helper to delete all TFTs for EPS bearer 
when a EPS bearer is removed, all associated TFTs need
to be removed as well.

Andre Puschmann 483a216bd5 ue,stack: refactor handling of radio bearears in UE stack 
this is a rather large commit that is hard to split because
it touches quite a few components.

It's a preparation patch for adding NR split bearers in the next
step.

We realized that managing RLC and PDCP bearers for both NR and LTE
in the same entity doesn't work. This is because we use the LCID
as a key for all accesses. With NR dual connectivity however we
can have the same LCID active at the same time for both LTE and NR
carriers.

The patch solves that by creating a dedicated NR instance for RLC/PDCP
in the stack. But then the question arises for UL traffic on, e.g. LCID 4
what PDCP instance the GW should use for pushing SDUs. It doesnt' know
that. And in fact it doesn't need to. It just needs to know EPS
bearer IDs. So the next change was to remove the knowledge of what
LCIDs are from the GW. Make is agnostic and only work on EPS bearer IDs.

The handling and mapping between EPS bearer IDs and LCIDs for LTE
or NR (mainly PDCP for pushing data) is done in the Stack because
it has access to both.

The NAS also has a EPS bearer map but only knows about default and
dedicated bearers. It doesn't know on which logical channels they
are transmitted.

was already stopped.

a reestablishment (UE).

Francisco 486823e5de sched,bugfix: The PHR handling scheme now considers the number of PRBs of the UL grant that carried the PHR. Before, it was assuming the most conservative scenario of Nprb=1 2021-06-03 15:33:38 +01:00
Andre Puschmann 018c734b09 dl_harq: fix unlocking of unlocked mutex bug detected by TSAN 
in the mac_test the tb_decoded() method was called twice for
the 2nd codeword, causig TSAN to complain about an unlocked mutex
being unlocked.

The patch resolves the potential issue only calling tb_decoded
for a grant/tb thas has a non-zero MCS.

The patch also adjusts the reset function to have a safe and "unsafe"
version to be called from inside the class, similar to other
classes where we do the same.
