How does the forking process work in AFL/AFL++?

Regarding AFL and AFL++. It’s my understanding that the current testcase is selected and mutated in the main function (during stages). However, I am confused. Within the fuzz_one function, the target binary is ran and forked. Since the chosen testcase and its mutation is selected outside the scope of the fuzz_one function, how is the forked processes ran using different testcases and mutations? I had read somewhere that once the target binary is forked that it continues forking inside the forking function, but my best guess is that this is not the case since mutations are created outside of the scope of the functions which call fork.

Endless fuzzing farm

I want to do pipeline for a fuzzing farm, which will restart after successful completion of the keeper/host pipeline. What is needed is a restart, since the farm’s fuzzing pipeline should run indefinitely, and only a new successful run of the /master pipeline of new code in the master branch should lead to its restart.And want to run a fuzzing test without time limit.
