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.

Andre Puschmann 9e7d881bc8 srsenb: remove QAM256 related options in RRC Connection Reconfig 
this part of the RRC connection reconfig has caused issue for some
newer phones like the Iphone X, One Plus 6T.
The phone would receive the message but not respond with a reconfig
complete.

The patch fixes this issue by disabling QAM-256 support altogether.

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

Andre Puschmann 655c7ae8ae enb: fix warning when removing user 
when removing a user from the eNB we iterated over all possible LCIDs
and set the buffer state to zero in the scheduler.

this resulted in following log entries:

13:57:23.856334 [RRC ] [I] Received Release Complete rnti=0x46
13:57:23.856352 [MAC ] [W] [ 5149] The provided lcid=6 is not valid
13:57:23.856362 [MAC ] [W] [ 5149] The provided lcid=7 is not valid
13:57:23.856368 [MAC ] [W] [ 5149] The provided lcid=8 is not valid
13:57:23.856371 [MAC ] [W] [ 5149] The provided lcid=9 is not valid
13:57:23.856376 [MAC ] [W] [ 5149] The provided lcid=10 is not valid

we now check if the bearer exits at RLC and only report those to the MAC.

Andre Puschmann c16ac6c890 ue_stack: only push sync event to event queue is stack is still running 
stopping the UE in ZMQ mode caused a dead-lock because the Stack was
stopped before the PHY causing the sync queue to overflow. Since we
use a queue-length of 1 in ZMQ, mode, the PHY sync thread was blocking to
push a new sync event while the stack thread was already stopped.

this patch makes sure no new sync events are queued after the stack has
been terminated.

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

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 92d76a5eb6 mac_test: update tests involving BSR handling 
* split existing BSR test into dedicated test for short, long, and trunc
  BSR tests

* update MAC tests that include packing UL BSR.
  (After checking TS 36.321 again it seems we have reported old UL buffer states)

Andre Puschmann 1d1d52f3e6 enb: fix stopping of input thread 
since we've used a blocking read of stdin (with std::getline())
we had a race when the eNB was stopped and the user was still making
keyboard inputs. this is because the we didn't wait until the input
thread was terminated until we stopped the eNB.

we know use poll to query stdin (getline has no timeout mechanism).
