2024-03-25kernel: filedesc: Return status in fd_alloc()Ian Moffett

2024-03-18kernel: Add copyin() and copyout() routinesIan Moffett
This commit adds two new functions, copyin() and copyout() for kernel to userspace access and vice versa. These functions ensure the userspace address being accessed actually belongs to the process running by performing address range checks, thereby preventing bad addresses being passed to syscalls.
