Ismael Gomez c1c5fa426c Fix issue with new way of managing ul buffers not working with CA 4 years ago
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. 4 years ago

Andre Puschmann dadff1a947 pdu: default initialize pdu members with MAC log
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.

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.

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.
