Ismael Gomez 6348ddefd5 Add option to run prach_worker in the caller thread instead of by a background worker. This is useful when running simulations with ZMQ, to avoid the prach worker to take too much time and miss the RAR deadline 4 years ago

Andre Puschmann 35373d1385 enb,ue: add cmdline arg to enable usage of default LTE sample rate 
some RF boards might have issues with the sharp filters that are needed
for the reduced sample rate operation that we use by default.

This switch allows to use the default LTE sampling rates and
configure this at run-time, not compile time.

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).

to allow the signal handler to flush the file if the alarm goes off.

Pau Espin Pedrol 4949df257e Proper shutdown on SIGHUP 
If a process exits and has a controlling terminal, everything under
it gets a SIGHUP by the kernel. That's the case for instance when
running a srsUE over ssh with some specific parameters. As a result,
when the ssh client is killed, SIGHUP is sent to srsUE, which will be
killed immediatelly without proper release, which means in turn that log
buffers are not flushed.
Let's do proper shutdown when SIGHUP is received so that everyone can
get log files.

Andre Puschmann fef6893ce4 make user activity handling independent of system time 
this commit removes the getsystime() call from the activity handling.
it uses a single timer per UE to handle its activity.

three different timer values exist. one for the Msg3 reception. This
is like before and is quite low to quickly remove fake UEs from the
RRC. The second is a generic value (set to 1s for now) that covers
the entire UE configuration phase where multiple messages are sent
back and forth until the UE is fully set up and the default
bearer runs. From there on, the UE inactivity timer is used which
may be much bigger than 1s.
