Francisco Paisana da70c0fdaf fix cellsToAddModList handling. Now the eNB always adds PCell+SCells as measObjects in the RRC Reconfiguration messages. It may also further include cellsToAddModList if they are provided in the rr.conf file 2020-09-25 15:03:58 +01:00

faluco f0d651ae8e - Fixed a leak in the MME class not releasing the static byte buffer pool.

Francisco Paisana dcf5a727f2 do not send RRC release in case the eNB receives a S1AP UEContextRelease command and the UE is doing handover. Handle GTPU end marker 2020-09-22 16:51:45 +01:00
Francisco Paisana 13a5bfb525 - fix reestablishment reject transmission in the srsenb. For SRB0 SDUs, no RLC header is required, so we do not need to check in such case if there is enough space in the TB for the header. 
- fix srsenb reestablishment check for UE context. The pci has to be accounted for the srsenb to understand that the UE trying to do reestablishment corresponds to one of its own

Andre Puschmann 655c7ae8ae enb: fix warning when removing user 
when removing a user from the eNB we iterated over all possible LCIDs
and set the buffer state to zero in the scheduler.

this resulted in following log entries:

13:57:23.856334 [RRC ] [I] Received Release Complete rnti=0x46
13:57:23.856352 [MAC ] [W] [ 5149] The provided lcid=6 is not valid
13:57:23.856362 [MAC ] [W] [ 5149] The provided lcid=7 is not valid
13:57:23.856368 [MAC ] [W] [ 5149] The provided lcid=8 is not valid
13:57:23.856371 [MAC ] [W] [ 5149] The provided lcid=9 is not valid
13:57:23.856376 [MAC ] [W] [ 5149] The provided lcid=10 is not valid

we now check if the bearer exits at RLC and only report those to the MAC.

Andre Puschmann 1d1d52f3e6 enb: fix stopping of input thread 
since we've used a blocking read of stdin (with std::getline())
we had a race when the eNB was stopped and the user was still making
keyboard inputs. this is because the we didn't wait until the input
thread was terminated until we stopped the eNB.

we know use poll to query stdin (getline has no timeout mechanism).

Matt Johnson 00940f0dbf srsenb: Add inline documentation for sib7 in example configs 2020-08-25 11:28:01 +02:00
Matt Johnson e9eab89a6b srsenb/rrc: Avoid crash when CSFB requested but sib7 not configured 
This commit addresses an issue where if a UE requests a release for
circuit switched fallback, but the sib7 carrier freqs info list is not
configured, the eNodeB would crash with a segfault due to attempting
to access an element from an empty list. This commit adds explicit
checking to handle the empty list case. If the list is empty, no
redirect carrier info is added to the connection release message and
the UE must scan for the fallback network itself.

Andre Puschmann 5e40bfe72c mac_pdu: unpack and print BSR index as well as BSR value in bytes 
before the BSR was extracted but the actual index (between 0 and 63)
was not stored but directly converted into bytes.

for log parsing and debugging it is easier to follow the index
value. this patch therefore adds both values to the log message
and extends the API accordingly.

In order to simplify testing with other bandwidths we change the default EARFCN.

Andre Puschmann a7911f0dab pdcp,rlc: refactor SDU queueing policy 
this patch refactors the SDU queuing and dropping policy of the RLC and PDCP layer.
the previous design had issues when packets have been generated at a higher
rate above the PDCP than they could be consumed below the RLC.

When the RLC SDU queues were full, we allowed two policies, one to block on the write
and the other to drop the SDU. Both options are not ideal because they either
lead to a blocking stack thread or to lost PDCP PDUs.

To avoid this, this patch makes the following changes:

* PDCP monitors RLC's SDU queue and drops packets on its north-bound SAP if queues are full
  * a new method sdu_queue_is_full() has been added to the RLC interface for PDCP
* remove blocking write from pdcp and rlc write_sdu() interface
  * all writes into queues need to be non-blocking
  * if Tx queues are overflowing, SDUs are dropped above PDCP, not RLC
* log warning if RLC still needs to drop SDUs
  * this case should be avoided with the monitoring mechanism
