Implementations

impl<A: AES128<'static> + AES128Ctr + AES128CBC + AES128ECB + AES128CCM<'static> + AES128GCM<'static>> AesDriver<'static, A>

pub fn new( aes: &'static A, source_buffer: &'static mut [u8], dest_buffer: &'static mut [u8], grant: Grant<App, UpcallCount<1>, AllowRoCount<{ ro_allow::COUNT }>, AllowRwCount<{ rw_allow::COUNT }>>, ) -> AesDriver<'static, A>

fn crypt_done( &self, buf: &'static mut [u8], res: Result<(), ErrorCode>, tag_is_valid: bool, )

res is Ok(()) if the encryption/decryption process succeeded. This does not mean that the message has been verified in the case of decryption. If we are encrypting: tag_is_valid is true iff res is Ok(()). If we are decrypting: tag_is_valid is true iff res is Ok(()) and the message authentication tag is valid.

fn command( &self, command_num: usize, data1: usize, data2: usize, processid: ProcessId, ) -> CommandReturn

System call for a process to perform a short synchronous operation or start a long-running split-phase operation (whose completion is signaled with an upcall). Command 0 is a reserved command to detect if a peripheral system call driver is installed and must always return a CommandReturn::success.

fn allocate_grant(&self, processid: ProcessId) -> Result<(), Error>

Request to allocate a capsule’s grant for a specific process.

fn allow_userspace_readable( &self, app: ProcessId, which: usize, slice: ReadWriteProcessBuffer, ) -> Result<ReadWriteProcessBuffer, (ReadWriteProcessBuffer, ErrorCode)>

System call for a process to pass a buffer (a UserspaceReadableProcessBuffer) to the kernel that the kernel can either read or write. The kernel calls this method only after it checks that the entire buffer is within memory the process can both read and write.
