Laurent THOMAS a1b4220a91 Exclusively use OAI_RNGSEED env variable everywhere 
Hide normal table initialization of Ziggurat generator from outside to
force the usage of randominit() for RNG initialization. In this step,
remove the randominit() seed parameter and only rely on OAI_RNGSEED for
a consistent RNG initialization, as this parameter was used differently
("0" as fixed number or to force a random seed).

Now, only use OAI_RNGSEED env variable to force the usage of a fixed
seed.

Laurent THOMAS 9ce9c16e36 Add documentation on PRACH processing 2025-10-30 23:01:06 +01:00
Laurent THOMAS d8d1520580 reduce sl_ahead to catch the RACH Msg1 in time in 24PRB test 
a bit difficult to understand: sl_ahead=6 => we systematically miss the
rach detection in the scheduler because the scheduler runs more than 6
slots ahead the rx slot processing (here > 11 slots because 6 (DL and UL
slots) + 4 (RU_RX_SLOT_DEPTH, so UL only))

so, reducing sl_ahead works better than large sl_ahead because the idea
behind is: the scheduler of slot+sl_ahead will never create work to do
in a UL slot before slot+sl_ahead+X (as minimum k2 is X, in the 24PRB CI
test: 6)

Laurent THOMAS d745e6fcd3 Make the decidated structure the PRACH decoding values contextual 
The function rx_nr_prach become autonomous, it doesn't read anymore global variables
So, it can become (later) a threadpool work, that will send a message when it finishes
rx_nr_prach_ru() still use some global variables, but it is executed in sequence, inside the ru main loop, that limits the probability of race conditions

Laurent THOMAS c4f4f8d919 Remove threequarter_fs, log_level; make functions static 
2 functions with same name as static to make it clearer they are separate.

remove unused copy of log_level global var.

remove threequarter sampling variable from the radio board general
configuration. The decision of sampling rate is made above. A better
behavior can be done later, like ask to the radio board what sampling
rate it can do,then use it to decide the appropiate sampling rate from
the gNB configuration. In UE case, it is another issue, as the sampling
rate would change after we decode SIB1, but also it is not developped
yet.

Laurent THOMAS 990fc9c55a Fix potential out-of-bound write 
Tell strncpy() the size including the NULL byte to make sure we copy all
data.

This just fixes these warnings:

    openair3/NAS/TOOLS/conf_usim.c: In function ‘gen_usim_data’:
    openair3/NAS/TOOLS/conf_usim.c:191:17: warning: ‘strncpy’ output truncated before terminating nul copying as many bytes from a string as its length [-Wstringop-truncation]
    openair3/NAS/TOOLS/conf_usim.c:190:53: note: length computed here
    openair3/NAS/TOOLS/conf_usim.c:195:17: warning: ‘strncpy’ output truncated before terminating nul copying as many bytes from a string as its length [-Wstringop-truncation]
    openair3/NAS/TOOLS/conf_usim.c:194:54: note: length computed here

add copy with limited size and truncate properly with null C string termination.

As clang-format doesn't handle tab indented files and as it is not the
OAI coding rule, the entire file is re-indented with present OAI coding
rule.

- Remove the --rfsimulator.hanging-workaround option
- Replace global nb_ue and Sockmutex with nb_cnx and Sockmutex
  in rfsimulator_state_t for better concurrency and clarity.
