remove several unused files
remove mem_block_t that is never used in a different way than a simple heap buffer
move up IP address type and remove duplications of the same struct declaration
- store the assoc ID of a UE at the RRC
- if F1 receives an SCTP shutdown, it removes the endpoint
- F1 will also send an "F1 Lost Connection" message to the RRC
- it is not yet possible to reconnect a DU after it had already been
connected at the CU, since the CU F1AP task will try to rebind GTP,
which fails
This branch series implements the usage of the F1 Setup Request
internally at the gNB, even if CU and DU run in the same process. Until
now, the F1 Setup Request contained struct fields to pass IP
configuration to the F1AP module; this information is not necessary in
monolithic, nor should it be relevant when passing the information in
F1 Setup Request.
Therefore, this commit moves all IP connection-related information out
of the F1 Setup Request and into a separate structure instead. In order
to give the F1AP module the necessary connection information, the
DU_REGISTER_REQ message is introduced that combines the F1 Setup Request
and IP configuration, such that the F1AP module can setup the SCTP
connection and then send the F1 Setup Request message.
In a later commit, there will be a callback for F1 Setup Request at MAC
to simply register the DU at the CU. The monolithic callback will simply
forward the F1 Setup Request The F1AP callback will look up the IP
configuration and create DU_REGISTER_REQ message containing IP
configuration and F1 Setup Request, which is then handled by the F1AP
module. To this end, a separate function in gnb_config.c allows to read
IP information from configuration.
The UE had a list of known UEs. With the introduction of a separate
module for F1 UE ID handling that is also used in monolithic (to
separate CU UE ID from DU UE ID), this functionality is not needed, and
deleted in this commit.
ENB_MODE is a cmake option to swap the order of include directories.
This has historical reasons; before OAI used cmake, it was very
sensitive to the order of includes. Nowadays, the order does not matter.
Remove this option, and fix the compilation issues that arise while
doing so.
OAI is riddled with boolean_t, FALSE, TRUE, etc. This makes no sense, as
there is a standard bool type, and could lead to nasty bugs if a
definition of a bool is non-standard (0 == false, true == !false). This
commit removes all non-standard bools in the whole project.
