I am looking to write my first driver. This driver will create a single character device, which can be opened by any user. The device will support one ioctl: long ioctl_syscall(int fd, long syscall, long args[6]); This is simply equivalent to: syscall(syscall, args[0], args[1], args[2], args[3], args[4], args[5], args[6]); and indeed I want it to behave *identically* to that. That means that ptracers are notified about the syscall (and given the opportunity to update its arguments), and that seccomp_bpf filters are applied. Furthermore, it means that all arguments to the syscall need full validation, as if they came from userspace (because they do). Is there an in-kernel API that allows one to invoke an arbitrary syscall with arguments AND proper ptrace/seccomp_bpf filtering? If not, how difficult would it be to create one?
