I've a general question: In Multiprocessor (Multi-Core) (SMP) environment how does fork system call (do_fork() related code) maintain the synchronization in case the threads of a process are running on different processors? E.g. it can happen that the fork() is called by cpu-0 thread and other thread of same process is executing on cpu-1.
I can see that copy of the process is made by do_fork() code in fork.c. Can anyone give more details how the concurrency issue gets handled e.g. how PC and Regs are of cpu-1 thread get copied without any race condition in SMP / multiprocessor system?
