nbd: Tidy up blockdev-add interface SocketAddress is a simple union, and simple unions are awkward: they have their variant members wrapped in a "data" object on the wire, and require additional indirections in C. I intend to limit its use to existing external interfaces, and convert all internal interfaces to SocketAddressFlat. BlockdevOptionsNbd is an external interface using SocketAddress. We already use SocketAddressFlat elsewhere in blockdev-add. Replace it by SocketAddressFlat while we can (it's new in 2.9) for simplicity and consistency. For example, { "execute": "blockdev-add", "arguments": { "node-name": "foo", "driver": "nbd", "server": { "type": "inet", "data": { "host": "localhost", "port": "12345" } } } } becomes { "execute": "blockdev-add", "arguments": { "node-name": "foo", "driver": "nbd", "server": { "type": "inet", "host": "localhost", "port": "12345" } } } Since the internal interfaces still take SocketAddress, this requires conversion function socket_address_crumple(). It'll go away when I update the interfaces. Unfortunately, SocketAddress is also visible in -drive since 2.8: -drive if=none,driver=nbd,server.type=inet,server.data.host=127.0.0.1,server.data.port=12345 Nobody should be using it, as it's fairly new and has never been documented, so adding still more compatibility gunk to keep it working isn't worth the trouble.

Unfortunately, we cannot just flatten all of the addresses because nbd-server-start still takes a plain SocketAddress.

nbd-client: Refuse read-only client with BDRV_O_RDWR The NBD spec says that clients should not try to write/trim to an export advertised as read-only by the server. But we failed to check that, and would allow the block layer to use NBD with BDRV_O_RDWR even when the server is read-only, which meant we were depending on the server sending a proper EPERM failure for various commands, and also exposes a leaky abstraction: using qemu-io in read-write mode would succeed on 'w -z 0 0' because of local short-circuiting logic, but 'w 0 0' would send a request over the wire (where it then depends on the server, and fails at least for qemu-nbd but might pass for other NBD implementations). With this patch, a client MUST request read-only mode to access a server that is doing a read-only export, or else it will get a message like: can't open device nbd://localhost:10809/foo: request for write access conflicts with read-only export It is no longer possible to even attempt writes over the wire (including the corner case of 0-length writes), because the block layer enforces the explicit read-only request; this matches the behavior of qcow2 when backed by a read-only POSIX file. Fix several iotests to comply with the new behavior (since qemu-nbd of an internal snapshot, as well as nbd-server-add over QMP, default to a read-only export, we must tell blockdev-add/qemu-io to set up a read-only client).

nbd: Tidy up blockdev-add interface SocketAddress is a simple union, and simple unions are awkward: they have their variant members wrapped in a "data" object on the wire, and require additional indirections in C. I intend to limit its use to existing external interfaces, and convert all internal interfaces to SocketAddressFlat. BlockdevOptionsNbd is an external interface using SocketAddress. We already use SocketAddressFlat elsewhere in blockdev-add. Replace it by SocketAddressFlat while we can (it's new in 2.9) for simplicity and consistency. For example, { "execute": "blockdev-add", "arguments": { "node-name": "foo", "driver": "nbd", "server": { "type": "inet", "data": { "host": "localhost", "port": "12345" } } } } becomes { "execute": "blockdev-add", "arguments": { "node-name": "foo", "driver": "nbd", "server": { "type": "inet", "host": "localhost", "port": "12345" } } } Since the internal interfaces still take SocketAddress, this requires conversion function socket_address_crumple(). It'll go away when I update the interfaces. Unfortunately, SocketAddress is also visible in -drive since 2.8: -drive if=none,driver=nbd,server.type=inet,server.data.host=127.0.0.1,server.data.port=12345 Nobody should be using it, as it's fairly new and has never been documented, so adding still more compatibility gunk to keep it working isn't worth the trouble. You now have to use -drive if=none,driver=nbd,server.type=inet,server.host=127.0.0.1,server.port=12345 Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-id: 1490895797-29094-9-git-send-email-armbru@redhat.com [mreitz: Change iotest 147 accordingly] Because of this interface change, iotest 147 has to be adapted. Unfortunately, we cannot just flatten all of the addresses because nbd-server-start still takes a plain SocketAddress. Therefore, we need both and this is most easily achieved by writing the SocketAddress into the code and flattening it where necessary.
