Subject: [PATCH 00/29] block/export: Add infrastructure and QAPI for block exports
Date: Mon, 7 Sep 2020 20:19:42 +0200 [thread overview]
Message-ID: <20200907182011.521007-1-kwolf@redhat.com> (raw)
We are planning to add more block export types than just NBD in the near
future (e.g. vhost-user-blk and FUSE). This series lays the ground for
this with some generic block export infrastructure and QAPI interfaces
that will allow managing all of them (for now add/remove/query).
As a side effect, qemu-storage-daemon can now map --export directly to
the block-export-add QMP command, similar to other command line options.
The built-in NBD servers also gains new options that bring it at least a
little closer to feature parity with qemu-nbd.
Kevin Wolf (29):
nbd: Remove unused nbd_export_get_blockdev()
qapi: Create block-export module
qapi: Rename BlockExport to BlockExportOptions
block/export: Add BlockExport infrastructure and block-export-add
qemu-storage-daemon: Use qmp_block_export_add()
qemu-nbd: Use raw block driver for --offset
block/export: Remove magic from block-export-add
nbd: Add max-connections to nbd-server-start
nbd: Add writethrough to block-export-add
nbd: Remove NBDExport.close callback
qemu-nbd: Use blk_exp_add() to create the export
nbd/server: Simplify export shutdown
block/export: Move refcount from NBDExport to BlockExport
block/export: Move AioContext from NBDExport to BlockExport
block/export: Add node-name to BlockExportOptions
block/export: Allocate BlockExport in blk_exp_add()
block/export: Add blk_exp_close_all(_type)
block/export: Add 'id' option to block-export-add
block/export: Move strong user reference to block_exports
block/export: Add block-export-del
block/export: Add BLOCK_EXPORT_DELETED event
block/export: Move blk to BlockExport
block/export: Create BlockBackend in blk_exp_add()
block/export: Add query-block-exports
block/export: Move writable to BlockExportOptions
nbd: Merge nbd_export_new() and nbd_export_create()
nbd: Deprecate nbd-server-add/remove
iotests: Factor out qemu_tool_pipe_and_status()
iotests: Test block-export-* QMP interface
