Removing references to memcpy_dl_config_req and
memcpy_tx_req because these functions are leaking
memory. For our standalone mode we have created
new/modified memcpy_dl/tx_req functions.
- a new section in the configuration file to select security algorithms,
with new code to deal with it
- cleanup CG-ConfigInfo: specs seem to indicate that we must not
add mcg_RB_Config; the gNB has to deal with that
- as a consequence, modify fill_default_rbconfig() that is called in
every cases and needs security and bearer parameters
The new section in the configuration file looks like:
security = {
# preferred ciphering algorithms
# the first one of the list that an UE supports in chosen
# valid values: nea0, nea1, nea2, nea3
ciphering_algorithms = ( "nea0", "nea2" );
# preferred integrity algorithms
# the first one of the list that an UE supports in chosen
# valid values: nia0, nia1, nia2, nia3
integrity_algorithms = ( "nia0" );
};
The code is forced to use nea2, no matter what the UE supports.
After 2^18 PDCP packets, it will fail to work (we don't use HFN yet).
These limitations will be fixed in later commits.
The existing security function was not reused, because it does too
much memory allocation and initializes the security context at each
ciphering. So here comes nr_pdcp_security_nea2_cipher(). And also
the ciphering is done inplace. To be changed if necessary.
More accurately, we changed the do/while infinite
loop to be an infinite for loop for the read command of
the socket. The socket file descriptor choice is more clear now.
- sorted out according to recurring logic that wants function
prototypes in separate files from data struct and constants
definitions, variables in separate .c files with inclusion
of "extern" header files
- moved function prototypes to resective header files
- moved data structures and constants to respective header files
- merged unnecessary mac.h file into mac_defs.h @ MAC UE
- moved const variables suchs as tables to respective .c files
- moved extern references to respective extern.h files
