Ismael Gomez c1c5fa426c Fix issue with new way of managing ul buffers not working with CA 2021-01-19 16:59:36 +01:00
Ismael Gomez 0780f3caea pdu_queue must be non-blocking in order to avoid the ue or enb to block in the event of a memory leak and the buffer pool running out of buffers. In that case, the null return shall be handled properly and error logged. This commit restores commit c4c44c33f4. 2021-01-16 15:22:29 +01:00

MAC PDUs are default logged using the MAC log. So this gives
hex prints, etc. without having to manually set the logger for each
PDU.
 2021-01-12 20:24:20 +01:00
Andre Puschmann fcf481b83e pdu: add check when unpacking MAC PDUs to not read beyond PDU length 
we've checked the same when unpacking the subheaders but missed the
case where the payload was read beyond the PDU length, as has been
seen with a malformed RAR PDU.
 2021-01-12 20:24:20 +01:00
Andre Puschmann 10da7df194 pdu_test: add TC with malformed RAR PDU

Andre Puschmann 78b07daf3b pcap: make public interfaces thread-safe and handle fopen returning nullptr 
the previous patch only introduced a thread-safe queue between
PHY workers (writers) and PCAP writer thread (consumer).

However, it is also required to protect the ctor (and close()) to
prevent corrupted PCAP files.

The patch also correctly handles the case where the PCAP couldn't
be openend for writing and doesn't start the thread.

Pedro Alvarez 0ad0e9acac Make sure that RLC entity is only re-created if it switches modes. 2020-12-18 10:52:51 +00:00
Pedro Alvarez 0c20b7a455 Added support for S1AP modify bearer request support. This includes:

but not when only retransmitting segments.

This might lead to many more retx than allowed.

Francisco 99f94d9a1a Bug fixes of srseNB scheduler TPC 
- fix encoding of TPC command
- use of exponential average with irregular sampling for the ULSNR average estimate.
  Turns out using a time-windowed average for the SNR was a bad idea.
  If the UL grants are very sporadic, the SNR time window will never have samples
  when a TPC is encoded
- update of TPC sched test
- other fixes in accumulators lib

Francisco 2dc3fce9bd fix derivation of UL-64QAM support from the UE Capabilities in the eNB 
Before this PR, the eNB was not activating UL-64QAM if the UE release was below 12,
due to an erroneous convertion of the ASN1 EUTRA Capabilities struct into the flattened
srslte::ue_capabilities_t.

With this PR, the eNB activates UL-64QAM for the following cases:
- UE category 5
- UE category 8 and release >= 10
- UE category UL 8 and release >= 12

Andre Puschmann 43a6cd50e5 rf_imp: fix stopping of AGC thread 
hard killing of AGC thread causes issue on some RF devices,
such as the N310. The thread still seemed to access the device while
the radio was already killed (or the streamer object deleted).

It's unclear why this isn't causing similar issues on B210 or X310,
at least not visible, but it is obviously not the correct way to stop a thread.

The patch now correctly sets the stop flag for the AGC thread, wakes it
it up and waits until it has terminated.
