Server flags are not yet set (or used) correctly. #5
Description
The server should derive correct flags from the optional interfaces the Device supports (as well as the features we have implemented).
Relevant spec values:
- NBD_FLAG_HAS_FLAGS (should always be set)
- NBD_FLAG_READ_ONLY (make
WriteAtoptional?) - NBD_FLAG_SEND_FLUSH (make
Syncoptional?) - NBD_FLAG_SEND_FUA (The server does not yet support FUA for direct IO #2)
- NBD_FLAG_ROTATIONAL (FLAG_ROTATIONAL is not yet supported #11)
- NBD_FLAG_SEND_TRIM (CMD_TRIM is not yet supported #7)
- NBD_FLAG_SEND_WRITE_ZEROES (CMD_WRITE_ZEROES is not yet supported. #9)
- NBD_FLAG_SEND_DF (Structured replies are not yet supported #6)
- NBD_FLAG_CAN_MULTI_CONN (should always be set)
- NBD_FLAG_SEND_RESIZE (ignore, probably?)
- NBD_FLAG_SEND_CACHE (CMD_CACHE is not yet supported #12)
