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)

Ismael Gomez 0780f3caea pdu_queue must be non-blocking in order to avoid the ue or enb to block in the event of a memory leak and the buffer pool running out of buffers. In that case, the null return shall be handled properly and error logged. This commit restores commit c4c44c33f4. 4 years ago
Andre Puschmann fcf481b83e pdu: add check when unpacking MAC PDUs to not read beyond PDU length 
we've checked the same when unpacking the subheaders but missed the
case where the payload was read beyond the PDU length, as has been
seen with a malformed RAR PDU.

Andre Puschmann 2ca894df01 pdu: fortify RAR packing 
detected with ASAN trying to write negative number of padding bytes.

The patch checks the calculated length and returns with an error
if the length is negative.

Andre Puschmann c5514d7f80 pdu: fix to_string() for TA command 
the get_ta_cmd() is returning uint8_t which stringstream
interprets as ASCII character by default. So the log message is bogus.

Ismael Gomez f9a02299f9 Use MAC PDU pointer instead of tti_rx and rnti as a key to associate buffers. Decouple crc_info() and push_pdu() functions. This allows for different timing architectures in the PHY 4 years ago

Andre Puschmann 5f7f818abb pdu: fix bug in BSR table lookup 
the bug causes the BSR to return a bsr_idx of 0, i.e. no data
pending, when the buff_size was reported to be 1 B only.

Instead, the UE should return BSR idx 1, i.e. between 0 < BSR <= 10.

Andre Puschmann 035d989737 pdu: fix unpacking of LCG2 of LBSR MAC CE 
LBSR packing is fine but this makes the eNB do wrong things
because it thinkgs LCG2 has no or too much data to send.

LCG2 is our default LCG for DRB1. One occasion we saw the issue
is doing full rate TCP DL which requires quite a bit of ACK traffic
back to the sender. With the BSR for LCG2 being wrong, providing
UL grants was delayed and so the TCP DL throuhgput was very low.

In the log below we see that the buff_size[2]=1 so there is data to send.
Interestingly, the packing was correct so Wireshark displays it correctly.
But the unpacking not, as can be seen in the MAC log below which reports
0 buffer state for all LCGs

22:08:54.804792 [MAC ] [I] [ 5084] pdu_get: sdu_len=1212, channel.sched_len=1213, bsr.buff_size[2]=1
22:08:54.804840 [MAC ] [I] [ 5084] UL LCID=3 len=1212 LBSR: b=0 0 0 0

Andre Puschmann 5e7de0a95b cmake: install individual libraries (common, phy, etc) 
this seems to be important for package maintainers
or people who use srslte components in other projects
thar require to link against static libs

so besides installing headers, the apps and the RF lib, we also
install all individual libraries

this fixes https://github.com/srsLTE/srsLTE/issues/500#
and https://github.com/softwareradiosystems/srsLTE/issues/1754

Andre Puschmann 33c050791f pdu: add missing to_string() content for MAC SCH PDU subheaders 
* add both scell activation CE
* add rnti to CRNTI and CONT RES CE

Andre Puschmann d48bc8837e pdu: refactor MAC PDU class 
this patch refactors the MAC PDU class, the main changes are:

* add to_string() method to pretty print PDU and subheaders
  This allows to have a single log entry per MAC PDU with all its
  contents.
  It removes the C-style fprint() method

* Simplity payload vs. w_payload_ce
  Before we've used payload when reading the PDU and w_payload_ce
  as a buffer when writing. In all getters we needed to differentiate
  between both. Now payload points to w_payload_ce initially and is
  only updated when parsing a new PDU.

* add various helpers, e.g. to get subheader index, update a BSR, ..

* fix PDU test to use new to_string() method

Andre Puschmann 49a7a90698 mac: simplify BSR packing logic 
simplify logic to check whether a BSR fits and, if so, which type.
before the check has been done in two places.

we now also accomodate for the CE subheader size.

Andre Puschmann 5e40bfe72c mac_pdu: unpack and print BSR index as well as BSR value in bytes 
before the BSR was extracted but the actual index (between 0 and 63)
was not stored but directly converted into bytes.

for log parsing and debugging it is easier to follow the index
value. this patch therefore adds both values to the log message
and extends the API accordingly.
