Modified files: sys/kern : kern_fork.c Log message: Make a child execute fork_return() only if PTRACE_FORK has been specified. fork_return() does an additional check to send a SIGTRAP (for a debugger) but this signal might overwrite the SIGSTOP generated by the parent doing a PT_ATTACH before the child has a change to execute any instruction. Prevent a race visible only on SP system with regress/sys/kern/ptrace2. ok kettenis@
