Andre Puschmann d441486f76 fading: fix heap buffer overflow in fading sim 
at the when applying the fading channel we copied the state back
to our buffer. Since we are offsetting the read buffer
by X samples, we need to make sure that we don't read after then
(len-X) samples of the temporary memory buffer
 4 years ago
Andre Puschmann 1199a79851 fix Scell sync for large cells 
the PSS detection needs more temporary buffer than a full subframe.
we therefore need to allocate and initialize the sync object with
larger maximum size to support Scell search of large cells, e.g.
20 MHz

this fixes issue #1538

Andre Puschmann f6d3467884 ringbuffer: fix timeout calculation for timed read 
with ZMQ RF, we've seen the radio returning -1 and traced
the issue down to the ringbuffer.
in fact, pthread_cond_timedwait() returned 22 (EINVAL) indicating
a wrong timeout value. The issue was likely an overflow
in the timespec parameter. This patch checks for the return
value of pthread_cond_timedwait() and also calculates the
nanosecond wrap around for the timespec
 4 years ago
Andre Puschmann aed38a6028 rf_zmq: increase default ZMQ timeout to 2s 
amarisoft flags an RF error and exits after not receiving samples
for the radio. Running with ZMQ in the RFCI, the UE sometimes needs more
time to start up due to slow processing and no fftw wisdom file and
then Amarisoft eNB times out. This gives the whole process a little
bit more time. Should we still find it too short we may increase
it further.

I experienced issues when the rx_type was set, but the rx_format was not. This led to "Unsupported sample format pub" as the tmp variable is still set to the value of the rx_type.

Andre Puschmann 53ab53ee77 ue_sync: fix tracking in GNSS_SYNC mode 
this fixes the subframe-accurate rx in tracking mode.
previously we've only alligned to the next subframe start in find and
when there was a single overflow we've lost the track.

this patch calculates the offset in samples to the actual start of the
subframe (full ms of the receive timestamp) vs. the actual
receive timestamp and uses the value as the "next_rf_sample_offset"
to realign on the next receive

we could turn off the warning using a pragma in the code
but I guess it's safe to just null-terminate after
copying manually

Andre Puschmann c7343cf6d8 protect sf_buffer from overrun in receive_samples 
this patch adds a buffer len paramter to the receive_samples() call
that protects the (also) provided buffer from overflowing.

currently each call to srslte_ue_sync_zerocopy() which then calls receive_samples()
relies on a buffer that is "big enough". But that buffer is sometimes
2 subframes, sometimes 3 or 5, sometimes has space for the maximum PRB size, sometimes
only for 6 PRBs (i.e. during cell search).

By extending the interface to pass the buffer size we can make sure that
only samples are received that actually fit inside the provided buffer.

Andre Puschmann 6a50fe3233 zmq: add monitor code for sockets but disable it 
according to the ZMQ dev guide, one can use a socket monitor
to get informed about changes to a socket, e.g. when a client disconnected.

This is useful to detect when a UE dropped the connection to reinitialize
the socket and timers in a eNB.

This commit adds code to create such a socket monitor but leaves
it disabled because it still doesn't work as expected.

Andre Puschmann 2a46413121 during cell search don't configure found cell as serving cell 
this fixes an issue in which, during cell search, the sync code
itself would set the serving cell whenever it found a new cell.

instead, only report the found cell to RRC and keep the sample
rate at 1.92 MHz. RRC may select a new serving cell and then tell
PHY to camp on it.

this has been detected by valgrind+gcc on Ubuntu 16.04 but
isn't an issue for more recent versions. Not sure if that is because
of an issue in older libc and there memcpy implementation or a
bug in valgrind, or both.

In any case, overlapping memcpy may cause undefined behaviour so
it seems ok to only copy the symbols that do not contain the
DMRS, i.e. not symbol 3 in each slot.

Andre Puschmann 0380c83175 remove RF device calibration settings from UE/eNB config 
- this remove RF calibration parameters that were an extra
  section in the eNB/UE config but were hardly used (only old bladeRF)
- a better way to pass those parameter would be through the
  device args in the normal rf config section

Zhe Huang 3433b0ffde assign correct values from BladeRf manual calibration to correction 
* Assign correct values from BladeRf manual calibration to correction

The rf_calibration function for blade RF was assgiing dc_gain to
BLADERF_CORR_FPGA_PHASE and dc_phase to BLADERF_CORR_FPGA_GAIN. This hot
fix corrects the value assignments in both rf_blade_set_tx_cal and
rf_blade_set_rx_cal functions.

IgnasJ 67c8bf1368 Fixes for srsLTE on ARM (#229) 
* Fix ARM NEON code compilation

Fix LV_HAVE_NEON defintion incorrecly used instead of HAVE_NEON in some places
Replace vqabsq_s32 with vabsq_f32 as vqabsq_s32 requires int type (fails to compile)
Fix missing NEON code path in mat.h in srslte_mat_2x2_mmse_csi_simd()

* Fix timestamp overflow issue on 32-bit systems with Soapy driver

'time_t secs' can be 32-bit on some systems. This causes calculation:
'secs * 1000000000;' to overflow.
