Andre Puschmann a09fb95c25 proc_ra: protect RA procedure from concurrent thread access
that patch addreses issue #2199 by defering RA-related calls that
are executed from within PHY workers.

The time-critical bits of more complex functions such as tb_decoded()
are still executed in the PHY worker thread but the state machine
manipulation is defered.

Andre Puschmann 2be85217fd mac,ue: reset demux when restting MAC
this potentially fixes the issue we see during HO and RLF
under high DL load.

The issue happens because buffered DL PDUs are delivered to
RLC after reestablishing RLC that confuse the receiving
RLC entity bc the sequence numbers are very high, as opposed
to begin with zero again after reestablishment.

Andre Puschmann 7cf919e2af Fix MAC PDU packing after sending Truncated BSR (#2004)
* mac_test: add extended TBSR unit test

unit test to MAC UL packing after sending a TBSR

this fixes the MAC issues described in issue #2002

* mux: fix updating of LCG buffer state after packing PDU

we've previously lowered the buffer state of the LCG according
to the bytes that have been scheduled, but not according to
those that have been actually included in the PDU.

* proc_bsr: fix LCG buffer state updating for TBSR

when sending a TBSR do not update the internal buffer
state of the BSR proc.

This caused issues because the buffer state for all LCG that
are not included in the TBSR are set to zero, although at least
one LCG does have data to transmit.

* rlc_am: include LCID when logging retx of SN

Andre Puschmann fd5cde525c proc_bsr: fix race condition in BSR reporting
fix for #1934

This fixes a race condition between Stack thread and DL
PDU processing that lead to updates of the RLC buffer that
are undetected by the BSR routine.

What happens is that in a UL SCH PDU all outstanding data is transmitted
and and a LBSR with all zero buffers is sent.

14:39:47.327301 [MAC ] [D] [ 3793] BSR:   LCID=3 old_buffer=59
14:39:47.330600 [MAC ] [I] [ 3793] UL LCID=3 len=58 LBSR: b=0 0 0 0

Note that "old_buffer" isn't set to zero here.

At the same time (same TTI), the MAC PDU processing thread handles DL-SCH PDUs
that may generate new UL PDUs:

14:39:47.330749 [RLC ] [I] DRB1 Tx SDU (54 B, tx_sdu_queue_len=1)
14:39:47.330762 [RLC ] [I] DRB1 Tx SDU (54 B, tx_sdu_queue_len=2)
14:39:47.330775 [RLC ] [I] DRB1 Tx SDU (54 B, tx_sdu_queue_len=3)
..

Those PDUs are "new data" since the previous buffer state was zero.

Here is the race now between the threads, at the end of the bsr::step() function
old_buffer of each LCG is updated with the previous new_buffer, so
the buffer state of LCG=2 is now 59.

Now MAC starts the next TTI:

14:39:47.331910 [MAC ] [D] [ 3794] Running MAC tti=3794
14:39:47.331928 [MAC ] [D] [ 3794] Update Bj: lcid=0, Bj=0
14:39:47.331934 [MAC ] [D] [ 3794] Update Bj: lcid=1, Bj=0
14:39:47.331938 [MAC ] [D] [ 3794] Update Bj: lcid=2, Bj=0
14:39:47.331941 [MAC ] [D] [ 3794] Update Bj: lcid=3, Bj=-1752
14:39:47.331951 [MAC ] [D] [ 3794] BSR:   LCID=0 update new buffer=0
14:39:47.331960 [MAC ] [D] [ 3794] BSR:   LCID=1 update new buffer=0
14:39:47.331964 [MAC ] [D] [ 3794] BSR:   LCID=2 update new buffer=0
14:39:47.331971 [MAC ] [D] [ 3794] BSR:   LCID=3 update new buffer=335
14:39:47.331976 [MAC ] [D] [ 3794] BSR:    check_new_data() -> get_buffer_state_lcg(0)=0
14:39:47.331980 [MAC ] [D] [ 3794] BSR:    check_new_data() -> get_buffer_state_lcg(1)=0
14:39:47.331984 [MAC ] [D] [ 3794] BSR:    check_new_data() -> get_buffer_state_lcg(2)=59
14:39:47.331988 [MAC ] [D] [ 3794] BSR:    check_new_data() -> get_buffer_state_lcg(3)=0
14:39:47.331993 [MAC ] [D] [ 3794] BSR:   LCID=0 old_buffer=0
14:39:47.332000 [MAC ] [D] [ 3794] BSR:   LCID=1 old_buffer=0
14:39:47.332003 [MAC ] [D] [ 3794] BSR:   LCID=2 old_buffer=0
14:39:47.332007 [MAC ] [D] [ 3794] BSR:   LCID=3 old_buffer=335

And since the buffer state of LCG=2 isn't zero, the new data for LCID=3 of that LCG is considered.
So effectivly, the BSR missed the "empty" buffer state for a fraction of time and doesn't
consider the outgoing data generated in the same TTI as new. It therefore
doesn't transmit a BSR.

Andre Puschmann fab86382c1 mac,rrc: add interface to set SR config explicitly without touching any other MAC function
when releasing PUCCH/SRS (see 5.3.13 in 36.331) we need to reset the SR config as well.
In our case, SR is handled by MAC so we need to (re-)configure MAC, not all of
MAC though, just SR.

Andre Puschmann aec18a93d1 mux,bsr: refactor UL buffer status reporting
this patch fixes the UL BSR as per TS 36.321, it includes following
main changes:

* report UL buffer state to reflect the UEs transmit buffer after
  the MAC UL PDU containing the BSR has been built.
  In other words, if the UE, for example, can transmit all outstanding
  data in an UL grant, it will not report any pending data to transmit.

* refactor MUX routines and subheader space calculation

it through log_h->info()

i've moved the old macro into a new header and used as as much
as possible. there are still places in the code where similar
macros are used but we would need to change the variable name
to replace them
