2020-03-09usb-serial: wakeup device on inputJason Andryuk1-1/+5
Currently usb-serial devices are unable to send data into guests with the xhci controller. Data is copied into the usb-serial's buffer, but it is not sent into the guest. Data coming out of the guest works properly. usb-serial devices work properly with ehci. Have usb-serial call usb_wakeup() when receiving data from the chardev. This seems to notify the xhci controller and fix inbound data flow. Also add USB_CFG_ATT_WAKEUP to the device's bmAttributes. This matches a real FTDI serial adapter's bmAttributes.

Make hot-plug/hot-unplug on PCIe Root Ports optional to allow libvirt manage it and restrict unplug for the whole machine. This is going to prevent user-initiated unplug in guests (Windows mostly). Hotplug is enabled by default. Usage: -device pcie-root-port,hotplug=off,...

2020-03-06block/rbd: Add support for ceph namespacesFlorian Florensa2-13/+34
Starting from ceph Nautilus, RBD has support for namespaces, allowing for finer grain ACLs on images inside a pool, and tenant isolation. In the rbd cli tool documentation, the new image-spec and snap-spec are : - [pool-name/[namespace-name/]]image-name - [pool-name/[namespace-name/]]image-name@snap-name When using an non namespace's enabled qemu, it complains about not finding the image called namespace-name/image-name, thus we only need to parse the image once again to find if there is a '/' in its name, and if there is, use what is before it as the name of the namespace to later pass it to rados_ioctx_set_namespace. rados_ioctx_set_namespace if called with en empty string or a null pointer as the namespace parameters pretty much does nothing, as it then defaults to the default namespace. The namespace is extracted inside qemu_rbd_parse_filename, stored in the qdict, and used in qemu_rbd_connect to make it work with both qemu-img, and qemu itself.

2020-03-06qemu-storage-daemon: Add --monitor optionKevin Wolf10-5/+121
This adds and parses the --monitor option, so that a QMP monitor can be used in the storage daemon. The monitor offers commands defined in the QAPI schema at storage-daemon/qapi/qapi-schema.json. The --monitor options currently allows to create multiple monitors with the same ID. This part of the interface is considered unstable. We will reject such configurations as soon as we have a design for the monitor subsystem to perform these checks. (In the system emulator, we depend on QemuOpts rejecting duplicate IDs.)

2020-03-06monitor: Create QAPIfied monitor_init()Kevin Wolf3-35/+80
This adds a new QAPI-based monitor_init() function. The existing monitor_init_opts() is rewritten to simply put its QemuOpts parameter into a visitor and pass the resulting QAPI object to monitor_init(). This will cause some change in those error messages for the monitor options in the system emulator that are now generated by the visitor rather than explicitly checked in monitor_init_opts().

2020-03-06qapi: Create 'pragma' moduleKevin Wolf3-25/+26
We want to share the whitelists between the system emulator schema and the storage daemon schema, so move all the pragmas from the main schema file into a separate file that can be included from both.

2020-03-06stubs: Update monitor stubs for qemu-storage-daemonKevin Wolf3-13/+24
Before we can add the monitor to qemu-storage-daemon, we need to add a stubs for monitor_fdsets_cleanup(). We also need to make sure that stubs that are actually implemented in the monitor core aren't linked to qemu-storage-daemon so that we don't get linker errors because of duplicate symbols. This is achieved by moving the stubs in question to a new file stubs/monitor-core.c.

2020-03-06qemu-storage-daemon: Add --chardev optionKevin Wolf2-1/+25
This adds a --chardev option to the storage daemon that works the same as the -chardev option of the system emulator. The syntax of the --chardev option is still considered unstable. We want to QAPIfy it and will potentially make changes to its syntax while converting it. However, we haven't decided yet on a design for the QAPIfication, so QemuOpts will have to do for now.

2020-03-06qemu-storage-daemon: Add main loopKevin Wolf2-0/+15
Instead of exiting after processing all command line options, start a main loop and keep processing events until exit is requested with a signal (e.g. SIGINT). Now qemu-storage-daemon can be used as an alternative for qemu-nbd that provides a few features that were previously only available from QMP, such as access to options only available with -blockdev and the socket types 'vsock' and 'fd'.

2020-03-06qemu-storage-daemon: Add --export optionKevin Wolf2-0/+58
Add a --export option to qemu-storage-daemon to export a block node. For now, only NBD exports are implemented. Apart from the 'type' option (which is the implied key), it maps the arguments for nbd-server-add to the command line. Example: --export nbd,device=disk,name=test-export,writable=on Signed-off-by: Kevin Wolf <kwolf@redhat.com> Message-Id: <20200224143008.13362-12-kwolf@redhat.com> Acked-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2020-03-06blockdev-nbd: Boxed argument type for nbd-server-addKevin Wolf3-27/+47
Move the arguments of nbd-server-add to a new struct BlockExportNbd and convert the command to 'boxed': true. This makes it easier to share code with the storage daemon.

2020-03-06qemu-storage-daemon: Add --nbd-server optionKevin Wolf5-2/+56
Add a --nbd-server option to qemu-storage-daemon to start the built-in NBD server right away. It maps the arguments for nbd-server-start to the command line, with the exception that it uses SocketAddress instead of SocketAddressLegacy: New interfaces shouldn't use legacy types, and the additional nesting would be nasty on the command line.

2020-03-06qapi: Flatten object-addKevin Wolf6-11/+68
Mapping object-add to the command line as is doesn't result in nice syntax because of the nesting introduced with 'props'. This becomes nicer and more consistent with device_add and netdev_add when we accept properties for the object on the top level instead. 'props' is still accepted after this patch, but marked as deprecated.

2020-03-06qemu-storage-daemon: Add --blockdev optionKevin Wolf4-2/+43
This adds a --blockdev option to the storage daemon that works the same as the -blockdev option of the system emulator. In order to be able to link with blockdev.o, we also need to change stream.o from common-obj to block-obj, which is where all other block jobs already are. In contrast to the system emulator, qemu-storage-daemon options will be processed in the order they are given. The user needs to take care to refer to other objects only after defining them.

2020-03-06block: Move sysemu QMP commands to QAPI block moduleKevin Wolf3-387/+387
QMP commands that are related to the system emulator and don't make sense in the context of tools such as qemu-storage-daemon should live in qapi/block.json rather than qapi/block-core.json. Move them there. The associated data types are actually also used in code shared with the tools, so they stay in block-core.json.

2020-03-06block: Move common QMP commands to block-core QAPI moduleKevin Wolf2-284/+283
block-core is for everything that isn't related to the system emulator. Internal snapshots, the NBD server and quorum events make sense in the tools, too, so move them to block-core.

2020-03-06block: Move system emulator QMP commands to block/qapi-sysemu.cKevin Wolf3-559/+592
These commands make only sense for system emulators and their implementations call functions that don't exist in tools (e.g. to resolve qdev IDs).

2020-03-06stubs: Add arch_typeKevin Wolf3-0/+7
blockdev.c uses the arch_type constant, so before we can use the file in tools (i.e. outside of the system emulator), we need to add a stub for it. A new QEMU_ARCH_NONE is introduced for this case.

2020-03-06qemu-storage-daemon: Add barebone toolKevin Wolf3-1/+129
This adds a new binary qemu-storage-daemon that doesn't yet do more than some typical initialisation for tools and parsing the basic command options --version, --help and --trace. Even though this doesn't add any options yet that create things (like --object or --blockdev), already document that we're planning to process them in the order they are given on the command line rather than trying (and failing, like vl.c) to resolve dependencies between options automatically.
