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

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 10da7df194 pdu_test: add TC with malformed RAR PDU 
a malformed RAR PDU should not be decoded further if the payload
indicates a length beyond the actual PDU size.

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: 
- Handle received E-RAB S1AP at s1ap.cc.
 - Added methods to rrc.cc, rrc_ue.cc and rrc_bearer_cfg.cc to handle erab modify request.
 - Made RLC add_bearer() function capable of re-creating the RLC entity.
 - Send RRC reconfiguration to the UE and reply to the EPC with S1AP
   modify bearer response.

This commit also adds support to srsEPC to send S1AP modify bearer request for
testing purposes.
