| 2024-03-18 | kernel: Add copyin() and copyout() routines | Ian 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.
