2024-03-25 | kernel: filedesc: Return status in fd_alloc() | Ian Moffett | |
It is better for fd_alloc() to return the status and have one of the arguments point to an output than have fd_alloc() return the allocated file descriptor just like that. Signed-off-by: Ian Moffett <ian@osmora.org> | |||

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.

2024-03-16 | kernel: syscall: Remove syscall_args.ret | Ian Moffett | |
