faluco c39ea2f583 Adjust possible type mismatch. 2020-05-08 21:17:05 +02:00
Andre Puschmann 189685b6f5 demod_soft: fix clang warning in demod NEON code 
Try to bring back compilation.
Disable temporarily Werror.

Re-enable two simd functions.
 2020-05-08 21:17:05 +02:00
Andre Puschmann f67524707d neon: add srslte_simd_b_neg() 
clang complained about an uinit var that is returned and it turned
out that we don't even implement that function in NEON.

I've found a nice MIT-licensed header that was easy to integrate.

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

Andre Puschmann 9648e47eb6 ue_cell_search_nbiot: fix potential out-of-bounds access

that is initialized and checked during init

Andre Puschmann 8185b7c793 ue_dl: fix potential out-of-bounds access when decoding DCIs 
fixes Coverity issue 1480088 where srslte_ue_dl_find_dl_dci() expects
an array of struct srslte_dci_dl_t but is only given one element.

srslte_ue_dl_find_and_decode() itself only uses the first decoded
message but find_dl_dci() may still decode more than that
