herlesupreeth 0f06ec0d9c Add feature to provide custom GTP-U (S1) address to be advertised inside S1AP messages 
This feature is useful in scenarios where eNB is behind a NAT and EPC on public cloud
Since eNB's GTP-U can only bind to IP address visible in it's host (usually a private IP beind a NAT), it advertises the same to UE in S1AP message
resulting in traffic from EPC to eNB (DL traffic) not able to reach eNB. This commit solves this issue by providing a means to advertise a different IP address than the one GTP-U UDP socket is bound to.
This IP is usually advertised in InitialContextSetupResponse and E-RABSetupResponse.

In order to make use of this feature, use the following parameter in enb.conf

Example:

gtp_advertise_addr = 213.61.141.82

of the same PDCP PDU.

faluco a2f6e13138 Add a tag to the string memory pool in fmt to discriminate between pool vs heap allocated buffers. Heap allocated buffers are used as a fallback mechanism when the buffer runs out of space. 2021-04-13 17:36:39 +02:00
faluco 0465f6badd Implement a pool in FMT to avoid allocating heap memory when passing a char* to the backend, usually when formatting a %s argument. 
Previously since a char* can have any length, this was managed by FMT by converting it into a std::string.
Now we store it into a configurable size node that can store a fixed size string, otherwise it falls back to std::string.

Andre Puschmann 48537f3fe7 pdcp,rlc: increase number of PDCP SDUs for notification from RLC 
the current value of 256 limits the number of PDCP SDUs that can be
notified from RLC. The limit is quickly hit when too many SDUs
are in flight. This can cause unwanted log entries and weird PDCP
behaviour.

the patch increases the value to 1024, which still can be too few if
many smaller SDUs are traveling.

The patch also set the log level to warning to quicker spot
misconfigs in logs.

Andre Puschmann 9950278a12 nr,mac_sch_pdu,mux: fix packing of MAC subPDUs with 16bit L field 
the created RLC PDU was too large to fit inside the MAC grant
because only the header room for the short L field was used.

The patch determines the correct size before passing the opportunity to RLC.

It also improves logging in error case by using the MAC logger instead of
stderr/stdout when error occurs.

faluco 54fab314c0 Enhance RRC eNB events: 
- Implement a common event "log_rrc" for all RRC events and discriminate by procedure using an enum.
- Log events for connection, reestablishment, reconfig, reject and release.
- Log the corresponding ASN1 message used by each procedure.
- Redefine the JSON object for this event to match the new structure.

Fixed a compilation error detected by the static analyzer in gcc9.3 where bounded_vector::data() was using taking the address of the internal buffer which confused it, prefer to use the data method of std::array.

data type is a configurable but fixed-size vector.

Andre Puschmann ceacf8508d rlc_am_lte: fix handling of maxretx 
this patch fixes the actions/handling after RLC detected
maxRetx reached for a given SN.

According to the TS, RLC should only inform upper layers and
not try to recover from the event itself.

As a consequence, we won't manipulate the Tx or Rx window.
As a result of this, we might retransmit a SN more than
the specified amount of times.

It's the task of RRC to reestablish the bearer to recover
from that.
