Andre Puschmann 9950278a12 nr,mac_sch_pdu,mux: fix packing of MAC subPDUs with 16bit L field 
the created RLC PDU was too large to fit inside the MAC grant
because only the header room for the short L field was used.

The patch determines the correct size before passing the opportunity to RLC.

It also improves logging in error case by using the MAC logger instead of
stderr/stdout when error occurs.

Andre Puschmann db496df1e6 mac_nr: add support for periodic BSR reporting 
building on the previous refactor this patch now adds support
for peridoic BSR reporting (using short BSR). It furthermore does
the following changes:

* add BSR packing
* add proc_bsr_nr unit test
* move mac_nr test code into test folder under src (needs to be done with other test code too)

Andre Puschmann 7188603f2e mac_nr: don't push MAC CE LCIDs to RLC when unpacking DL MAC PDU 
this should fix log warnings then demux was trying to feed MAC CEs
to RLC:

10:50:54.845116 [MAC ] [I] [ 1153] Handling subPDU 1/2: rnti=0x0 lcid=61, sdu_len=1
10:50:54.845117 [RLC ] [E] Radio bearer id must be in [0:11] - 61
10:50:54.845118 [RLC ] [W] LCID 61 doesn't exist. Dropping PDU.
10:50:54.845119 [MAC ] [I] [ 1153] Handling subPDU 2/2: rnti=0x0 lcid=63, sdu_len=33

Francisco dc763b5045 rlc am - fix bugs in buffered_pdcp_pdu_list 
The count and container elements were not being correctly updated in the events
of SN overwrite, clear(), clear_pdcp_sdu(sn) of sn that doesnt exist
 2021-04-08 20:11:15 +01:00
Francisco ebbb74e639 rlc am - use of circular_map container in RLC AM window 
The window elements are not being correctly cleaned up when clear() is called
or when overwritten by newer SN. Furthermore, the window count member is not being
correctly updated when the insertion of a newer SN overwrites the previous one.

I used the circular_map container to avoid this sort of bugs

Andre Puschmann 1a42e0b1d1 epc,nas: add error handling for all make_byte_buffer() calls 
not handling the case where allocation was failing was causing a
segfault. It seems that when doing high rate UDP iperf and
disconnecting the UE causes the buffer pool to become empty due
to the PDU buffering. Thus, causing a crash when attaching the UE again.
