[PATCH v2 00/15] qemu patches for 64-bit NBD extensions

[Eric Blake <eblake@redhat.com>]

This series implements the spec changes in a counterpart NBD series,
and has been tested to be interoperable with libnbd implementing the
same spec.  I'm not too happy with the RFC patch at the end, but
implemented it for discussion.  Given the release timing, this would
be qemu 8.0 material if we are happy with the direction the spec is
headed in.

Eric Blake (15):
  nbd/client: Add safety check on chunk payload length
  nbd/server: Prepare for alternate-size headers
  nbd: Prepare for 64-bit request effect lengths
  nbd: Add types for extended headers
  nbd/server: Refactor handling of request payload
  nbd/server: Refactor to pass full request around
  nbd/server: Initial support for extended headers
  nbd/server: Support 64-bit block status
  nbd/client: Initial support for extended headers
  nbd/client: Accept 64-bit block status chunks
  nbd/client: Request extended headers during negotiation
  nbd/server: Prepare for per-request filtering of BLOCK_STATUS
  nbd/server: Add FLAG_PAYLOAD support to CMD_BLOCK_STATUS
  RFC: nbd/client: Accept 64-bit hole chunks
  RFC: nbd/server: Send 64-bit hole chunk
