2022-11-02cryptodev: Add a lkcf-backend for cryptodevLei He
cryptodev: Added a new type of backend named lkcf-backend for cryptodev. This backend upload asymmetric keys to linux kernel, and let kernel do the accelerations if possible. The lkcf stands for Linux Kernel Cryptography Framework. Signed-off-by: lei he <helei.sig11@bytedance.com> Message-Id: <20221008085030.70212-5-helei.sig11@bytedance.com> Reviewed-by: Michael S.

2022-10-31block/blkio: Make driver nvme-io_uring take a "path" instead of a "filename"Alberto Faria
The nvme-io_uring driver expects a character special file such as /dev/ng0n1. Follow the convention of having a "filename" option when a regular file is expected, and a "path" option otherwise. This makes io_uring the only libblkio-based driver with a "filename" option, as it accepts a regular file (even though it can also take a block special file).

2022-10-28net: stream: add QAPI events to report connection stateLaurent Vivier
The netdev reports NETDEV_STREAM_CONNECTED event when the backend is connected, and NETDEV_STREAM_DISCONNECTED when it is disconnected. The NETDEV_STREAM_CONNECTED event includes the destination address. This allows a system manager like libvirt to detect when the server fails. For instance with passt: { 'execute': 'qmp_capabilities' } { "return": { } } { "timestamp": { "seconds": 1666341395, "microseconds": 505347 }, "event": "NETDEV_STREAM_CONNECTED", "data": { "netdev-id": "netdev0", "addr": { "path": "/tmp/passt_1.socket", "type": "unix" } } } [killing passt here] { "timestamp": { "seconds": 1666341430, "microseconds": 968694 }, "event": "NETDEV_STREAM_DISCONNECTED", "data": { "netdev-id": "netdev0" } } Signed-off-by: Laurent Vivier <lvivier@redhat.com> Acked-by: Michael S.

2022-10-28qapi: net: add stream and dgram netdevsLaurent Vivier
Copied from socket netdev file and modified to use SocketAddress to be able to introduce new features like unix socket. "udp" and "mcast" are squashed into dgram netdev, multicast is detected according to the IP address type. "listen" and "connect" modes are managed by stream netdev. An optional parameter "server" defines the mode (off by default) The two new types need to be parsed the modern way with -netdev, because with the traditional way, the "type" field of netdev structure collides with the "type" field of SocketAddress and prevents the correct evaluation of the command line option. Moreover the traditional way doesn't allow to use the same type (SocketAddress) several times with the -netdev option (needed to specify "local" and "remote" addresses). The previous commit paved the way for parsing the modern way, but omitted one detail: how to pick modern vs. traditional, in netdev_is_modern(). We want to pick based on the value of parameter "type". But how to extract it from the option argument? Parsing the option argument, either the modern or the traditional way, extracts it for us, but only if parsing succeeds. If parsing fails, there is no good option. No matter which parser we pick, it'll be the wrong one for some arguments, and the error reporting will be confusing. Fortunately, the traditional parser accepts *anything* when called in a certain way. This maximizes our chance to extract the value of "type", and in turn minimizes the risk of confusing error reporting.

2022-10-27hostmem: Allow for specifying a ThreadContext for preallocationDavid Hildenbrand
Let's allow for specifying a thread context via the "prealloc-context" property. When set, preallcoation threads will be crated via the thread context -- inheriting the same CPU affinity as the thread context. Pinning preallcoation threads to CPUs can heavily increase performance in NUMA setups, because, preallocation from a CPU close to the target NUMA node(s) is faster then preallocation from a CPU further remote, simply because of memory bandwidth for initializing memory with zeroes. This is especially relevant for very large VMs backed by huge/gigantic pages, whereby preallocation is mandatory.

2022-10-27util: Add write-only "node-affinity" property for ThreadContextDavid Hildenbrand
Let's make it easier to pin threads created via a ThreadContext to all host CPUs currently belonging to a given set of host NUMA nodes -- which is the common case. "node-affinity" is simply a shortcut for setting "cpu-affinity" manually to the list of host CPUs belonging to the set of host nodes. This property can only be written. A simple QEMU example to set the CPU affinity to host node 1 on a system with two nodes, 24 CPUs each, whereby odd-numbered host CPUs belong to host node 1: qemu-system-x86_64 -S \ -object thread-context,id=tc1,node-affinity=1 And we can query the cpu-affinity via HMP/QMP: (qemu) qom-get tc1 cpu-affinity [ 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47 ] We cannot query the node-affinity: (qemu) qom-get tc1 node-affinity Error: Insufficient permission to perform this operation But note that due to dynamic library loading this example will not work before we actually make use of thread_context_create_thread() in QEMU code, because the type will otherwise not get registered. We'll wire this up next to make it work. Note that if the host CPUs for a host node change due do CPU hot(un)plug CPU onlining/offlining (i.e., lscpu output changes) after the ThreadContext was started, the CPU affinity will not get updated.

2022-10-27util: Introduce ThreadContext user-creatable objectDavid Hildenbrand
Setting the CPU affinity of QEMU threads is a bit problematic, because QEMU doesn't always have permissions to set the CPU affinity itself, for example, with seccomp after initialized by QEMU: -sandbox enable=on,resourcecontrol=deny General information about CPU affinities can be found in the man page of taskset: CPU affinity is a scheduler property that "bonds" a process to a given set of CPUs on the system. The Linux scheduler will honor the given CPU affinity and the process will not run on any other CPUs. While upper layers are already aware of how to handle CPU affinities for long-lived threads like iothreads or vcpu threads, especially short-lived threads, as used for memory-backend preallocation, are more involved to handle. These threads are created on demand and upper layers are not even able to identify and configure them. Introduce the concept of a ThreadContext, that is essentially a thread used for creating new threads. All threads created via that context thread inherit the configured CPU affinity. Consequently, it's sufficient to create a ThreadContext and configure it once, and have all threads created via that ThreadContext inherit the same CPU affinity. The CPU affinity of a ThreadContext can be configured two ways: (1) Obtaining the thread id via the "thread-id" property and setting the CPU affinity manually (e.g., via taskset). (2) Setting the "cpu-affinity" property and letting QEMU try set the CPU affinity itself. This will fail if QEMU doesn't have permissions to do so anymore after seccomp was initialized. A simple QEMU example to set the CPU affinity to host CPU 0,1,6,7 would be: qemu-system-x86_64 -S \ -object thread-context,id=tc1,cpu-affinity=0-1,cpu-affinity=6-7 And we can query it via HMP/QMP: (qemu) qom-get tc1 cpu-affinity [ 0, 1, 6, 7 ] But note that due to dynamic library loading this example will not work before we actually make use of thread_context_create_thread() in QEMU code, because the type will otherwise not get registered. We'll wire this up next to make it work. In general, the interface behaves like pthread_setaffinity_np(): host CPU numbers that are currently not available are ignored; only host CPU numbers that are impossible with the current kernel will fail. If the list of host CPU numbers does not include a single CPU that is available, setting the CPU affinity will fail. A ThreadContext can be reused, simply by reconfiguring the CPU affinity. Note that the CPU affinity of previously created threads will not get adjusted.

2022-10-26blkio: add libblkio block driverStefan Hajnoczi
libblkio (https://gitlab.com/libblkio/libblkio/) is a library for high-performance disk I/O. It currently supports io_uring, virtio-blk-vhost-user, and virtio-blk-vhost-vdpa with additional drivers under development. One of the reasons for developing libblkio is that other applications besides QEMU can use it. This will be particularly useful for virtio-blk-vhost-user which applications may wish to use for connecting to qemu-storage-daemon. libblkio also gives us an opportunity to develop in Rust behind a C API that is easy to consume from QEMU. This commit adds io_uring, nvme-io_uring, virtio-blk-vhost-user, and virtio-blk-vhost-vdpa BlockDrivers to QEMU using libblkio. It will be easy to add other libblkio drivers since they will share the majority of code. For now I/O buffers are copied through bounce buffers if the libblkio driver requires it. Later commits add an optimization for pre-registering guest RAM to avoid bounce buffers. The syntax is: --blockdev io_uring,node-name=drive0,filename=test.img,readonly=on|off,cache.direct=on|off --blockdev nvme-io_uring,node-name=drive0,filename=/dev/ng0n1,readonly=on|off,cache.direct=on --blockdev virtio-blk-vhost-vdpa,node-name=drive0,path=/dev/vdpa...,readonly=on|off,cache.direct=on --blockdev virtio-blk-vhost-user,node-name=drive0,path=vhost-user-blk.sock,readonly=on|off,cache.direct=on Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Acked-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Stefano Garzarella <sgarzare@redhat.com> Message-id: 20221013185908.1297568-3-stefanha@redhat.com Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2022-10-17qmp/hmp, device_tree.c: introduce dumpdtbDaniel Henrique Barboza
To save the FDT blob we have the '-machine dumpdtb=<file>' property. With this property set, the machine saves the FDT in <file> and exit. The created file can then be converted to plain text dts format using 'dtc'. There's nothing particularly sophisticated into saving the FDT that can't be done with the machine at any state, as long as the machine has a valid FDT to be saved. The 'dumpdtb' command receives a 'filename' parameter and, if the FDT is available via current_machine->fdt, save it in dtb format to 'filename'. In short, this is a '-machine dumpdtb' that can be fired on demand via QMP/HMP. This command will always be executed in-band (i.e. holding BQL), avoiding potential race conditions with machines that might change the FDT during runtime (e.g. PowerPC 'pseries' machine).

2022-10-11i386: add notify VM exit supportChenyi Qiang
There are cases that malicious virtual machine can cause CPU stuck (due to event windows don't open up), e.g., infinite loop in microcode when nested #AC (CVE-2015-5307). No event window means no event (NMI, SMI and IRQ) can be delivered. It leads the CPU to be unavailable to host or other VMs. Notify VM exit is introduced to mitigate such kind of attacks, which will generate a VM exit if no event window occurs in VM non-root mode for a specified amount of time (notify window). A new KVM capability KVM_CAP_X86_NOTIFY_VMEXIT is exposed to user space so that the user can query the capability and set the expected notify window when creating VMs. The format of the argument when enabling this capability is as follows: Bit 63:32 - notify window specified in qemu command Bit 31:0 - some flags (e.g. KVM_X86_NOTIFY_VMEXIT_ENABLED is set to enable the feature.) Users can configure the feature by a new (x86 only) accel property: qemu -accel kvm,notify-vmexit=run|internal-error|disable,notify-window=n The default option of notify-vmexit is run, which will enable the capability and do nothing if the exit happens. The internal-error option raises a KVM internal error if it happens. The disable option does not enable the capability. The default value of notify-window is 0. It is valid only when notify-vmexit is not disabled. The valid range of notify-window is non-negative. It is even safe to set it to zero since there's an internal hardware threshold to be added to ensure no false positive. Because a notify VM exit may happen with VM_CONTEXT_INVALID set in exit qualification (no cases are anticipated that would set this bit), which means VM context is corrupted. It would be reflected in the flags of KVM_EXIT_NOTIFY exit. If KVM_NOTIFY_CONTEXT_INVALID bit is set, raise a KVM internal error unconditionally.

2022-10-09qmp: add QMP command x-query-virtio-queue-elementLaurent Vivier
This new command shows the information of a VirtQueue element. [Note: Up until v10 of this patch series, virtio.json had many (15+) enums defined (e.g. decoded device features, statuses, etc.). In v10 most of these enums were removed and replaced with string literals.

2022-10-09qmp: decode feature & status bits in virtio-statusLaurent Vivier
Display feature names instead of bitmaps for host, guest, and backend for VirtIODevices. Display status names instead of bitmaps for VirtIODevices. Display feature names instead of bitmaps for backend, protocol, acked, and features (hdev->features) for vhost devices. Decode features according to device ID. Decode statuses according to configuration status bitmap (config_status_map). Decode vhost user protocol features according to vhost user protocol bitmap (vhost_user_protocol_map). Transport features are on the first line. Undecoded bits (if any) are stored in a separate field. [Jonah: Several changes made to this patch from prev. version (v14): - Moved all device features mappings to hw/virtio/virtio.c - Renamed device features mappings (less generic) - Generalized @FEATURE_ENTRY macro for all device mappings - Virtio device feature map definitions include descriptions of feature bits - Moved @VHOST_USER_F_PROTOCOL_FEATURES feature bit from transport feature map to vhost-user-supported device feature mappings (blk, fs, i2c, rng, net, gpu, input, scsi, vsock) - New feature bit added for virtio-vsock: @VIRTIO_VSOCK_F_SEQPACKET - New feature bit added for virtio-iommu: @VIRTIO_IOMMU_F_BYPASS_CONFIG - New feature bit added for virtio-mem: @VIRTIO_MEM_F_UNPLUGGED_INACCESSIBLE - New virtio transport feature bit added: @VIRTIO_F_IN_ORDER - Added device feature map definition for virtio-rng ] Signed-off-by: Laurent Vivier <lvivier@redhat.com> Signed-off-by: Jonah Palmer <jonah.palmer@oracle.com> Message-Id: <1660220684-24909-4-git-send-email-jonah.palmer@oracle.com> Reviewed-by: Michael S.

2022-10-09qmp: add QMP command x-query-virtioLaurent Vivier
This new command lists all the instances of VirtIODevices with their canonical QOM path and name. [Jonah: @virtio_list duplicates information that already exists in the QOM composition tree. However, extracting necessary information from this tree seems to be a bit convoluted. Instead, we still create our own list of realized virtio devices but use @qmp_qom_get with the device's canonical QOM path to confirm that the device exists and is realized. If the device exists but is actually not realized, then we remove it from our list (for synchronicity to the QOM composition tree). Also, the QMP command @x-query-virtio is redundant as @qom-list and @qom-get are sufficient to search '/machine/' for realized virtio devices. However, @x-query-virtio is much more convenient in listing realized virtio devices.] Signed-off-by: Laurent Vivier <lvivier@redhat.com> Signed-off-by: Jonah Palmer <jonah.palmer@oracle.com> Message-Id: <1660220684-24909-2-git-send-email-jonah.palmer@oracle.com> Reviewed-by: Michael S.

This reverts commit b6522938327141235b97ab38e40c6c4512587373. Kevin Wolf NAKed this patch, because: 'file' is a required member (defined in BlockdevOptionsGenericFormat), removing it makes the example invalid. 'data-file' is only an additional optional member to be used for external data files (i.e. when the guest data is kept separate from the metadata in the .qcow2 file).

2022-07-20migration: Add postcopy-preempt capabilityPeter Xu
Firstly, postcopy already preempts precopy due to the fact that we do unqueue_page() first before looking into dirty bits. However that's not enough, e.g., when there're host huge page enabled, when sending a precopy huge page, a postcopy request needs to wait until the whole huge page that is sending to finish. That could introduce quite some delay, the bigger the huge page is the larger delay it'll bring. This patch adds a new capability to allow postcopy requests to preempt existing precopy page during sending a huge page, so that postcopy requests can be serviced even faster. Meanwhile to send it even faster, bypass the precopy stream by providing a standalone postcopy socket for sending requested pages. Since the new behavior will not be compatible with the old behavior, this will not be the default, it's enabled only when the new capability is set on both src/dst QEMUs. This patch only adds the capability itself, the logic will be added in follow up patches.

2022-07-20softmmu/dirtylimit: Implement dirty page rate limitHyman Huang(黄勇)
Implement dirtyrate calculation periodically basing on dirty-ring and throttle virtual CPU until it reachs the quota dirty page rate given by user. Introduce qmp commands "set-vcpu-dirty-limit", "cancel-vcpu-dirty-limit", "query-vcpu-dirty-limit" to enable, disable, query dirty page limit for virtual CPU. Meanwhile, introduce corresponding hmp commands "set_vcpu_dirty_limit", "cancel_vcpu_dirty_limit", "info vcpu_dirty_limit" so the feature can be more usable. "query-vcpu-dirty-limit" success depends on enabling dirty page rate limit, so just add it to the list of skipped command to ensure qmp-cmd-test run successfully.
