Subject: [PATCH v3 00/14] qemu patches for 64-bit NBD extensions
Date: Mon, 15 May 2023 14:53:29 -0500 [thread overview]
Message-ID: <20230515195343.1915857-1-eblake@redhat.com> (raw)
v2 was here:
https://lists.gnu.org/archive/html/qemu-devel/2022-11/msg02340.html
Since then:
- upstream NBD has accepted the extension on a branch; once multiple
implementations interoperate based on that spec, it will be promoted
to mainline (my plan: qemu with this series, libnbd nearly ready to
go, nbdkit a bit further out)
- rebase to block changes in meantime
- drop RFC patches for 64-bit NBD_CMD_READ (NBD spec did not take them)
- per upstream spec decision, extended headers now mandates use of
NBD_REPLY_TYPE_BLOCK_STATUS_EXT rather than server choice based on
reply size, which in turn required rearranging server patches a bit
- other changes that I noticed while testing with parallel changes
being added to libnbd (link to those patches to follow in the next
week or so)
Eric Blake (14):
nbd/client: Use smarter assert
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: Support 64-bit block status
nbd/server: Initial support for extended headers
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
