2309 * Notably absent: Proper permission management. This is sad, but it seems
2310 * almost impossible to achieve without changing the semantics and thereby
2311 * limiting the use cases of the qemu-io HMP command.
2312 *
2313 * In an ideal world we would unconditionally create a new BlockBackend for
2314 * qemuio_command(), but we have commands like 'reopen' and want them to
2315 * take effect on the exact BlockBackend whose name the user passed instead
2316 * of just on a temporary copy of it.
2317 *
2318 * Another problem is that deleting the temporary BlockBackend involves
2319 * draining all requests on it first, but some qemu-iotests cases want to
2320 * issue multiple aio_read/write requests and expect them to complete in
2321 * the background while the monitor has already returned.
2322 *
2323 * This is also what prevents us from saving the original permissions and
2324 * restoring them later: We can't revoke permissions until all requests
2325 * have completed, and we don't know when that is nor can we really let
2326 * anything else run before we have revoken them to avoid race conditions.
2327 *
2328 * What happens now is that command() in qemu-io-cmds.c can extend the
2329 * permissions if necessary for the qemu-io command. And they simply stay
2330 * extended, possibly resulting in a read-only guest device keeping write
2331 * permissions. Ugly, but it appears to be the lesser evil.
