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 795db30338 pdcp: drop PDCP control PDUs
this patch adds a check to drop all PDCP control PDUs
in order to prevent handling them as data PDUs.

This could happen when the size exceeded the arbitrary length check.

This should fix #1787

[REBASE] Make PHY non-blocking and fefactor HO procedure (#1753)
* Make PHY non-blocking and fefactor HO procedure

* makes entire PHY non-blocking through command interface
* adds dedicated queue for cell_search/cell_select commands
* refactor HO procedure to run faster, in one stack cycle. Looks closer to the specs
* force ue to always apply SIB2 configuration during reestablishment
* Run update_measurements in all workers

Andre Puschmann 6dc7841369 epoll_helper: move code to block OS signals into own helper function
before epoll can handle signals, the calling thread needs to block
them. the blocking needs to happen before any other threads get
spawned so they inherit the mask.

Bring back the circular array object. (#1712) 2020-09-09 17:16:47 +02:00
Andre Puschmann 6a56476b2a rlc: increase RLC Tx SDU queue
the Tx SDU has been set to 128 PDUs because this gives approx.
150kByte UL buffer state (max value for Rel 8 BSR).

Previously, however, we've always reported too much pending UL
data because we weren't subtracting the transmitted data from
the reported data.

with this newer BSR reporting, however, even with full buffers we would
never report full buffers because the queues size is too short.

This seems to cause issues for iperf TCP sessions not resulting
in full DL rate, see isse #1703. It seems that the TCP bandwitdh
probing works better with larger buffers (in our case this can
only be achieved with more PDUs in the pool).

This should fix #1703
