2024-07-03hostmem: add a new memory backend based on POSIX shm_open()Stefano Garzarella2-0/+124
shm_open() creates and opens a new POSIX shared memory object. A POSIX shared memory object allows creating memory backend with an associated file descriptor that can be shared with external processes (e.g. vhost-user). The new `memory-backend-shm` can be used as an alternative when `memory-backend-memfd` is not available (Linux only), since shm_open() should be provided by any POSIX-compliant operating system. This backend mimics memfd, allocating memory that is practically anonymous. In theory shm_open() requires a name, but this is allocated for a short time interval and shm_unlink() is called right after shm_open(). After that, only fd is shared with external processes (e.g., vhost-user) as if it were associated with anonymous memory. In the future we may also allow the user to specify the name to be passed to shm_open(), but for now we keep the backend simple, mimicking anonymous memory such as memfd.

2024-06-24backends: Introduce HostIOMMUDevice abstractZhenzhong Duan2-0/+34
A HostIOMMUDevice is an abstraction for an assigned device that is protected by a physical IOMMU (aka host IOMMU). The userspace interaction with this physical IOMMU can be done either through the VFIO IOMMU type 1 legacy backend or the new iommufd backend. The assigned device can be a VFIO device or a VDPA device. The HostIOMMUDevice is needed to interact with the host IOMMU that protects the assigned device. It is especially useful when the device is also protected by a virtual IOMMU as this latter use the translation services of the physical IOMMU and is constrained by it. In that context the HostIOMMUDevice can be passed to the virtual IOMMU to collect physical IOMMU capabilities such as the supported address width. In the future, the virtual IOMMU will use the HostIOMMUDevice to program the guest page tables in the first translation stage of the physical IOMMU. Introduce .realize() to initialize HostIOMMUDevice further after instance init.

As the comment in qapi/error, passing @errp to error_prepend() requires ERRP_GUARD(): * = Why, when and how to use ERRP_GUARD() = * * Without ERRP_GUARD(), use of the @errp parameter is restricted: ... * - It should not be passed to error_prepend(), error_vprepend() or * error_append_hint(), because that doesn't work with &error_fatal. * ERRP_GUARD() lifts these restrictions. * * To use ERRP_GUARD(), add it right at the beginning of the function. * @errp can then be used without worrying about the argument being * NULL or &error_fatal. ERRP_GUARD() could avoid the case when @errp is &error_fatal, the user can't see this additional information, because exit() happens in error_setg earlier than information is added [1]. The iommufd_backend_set_fd() passes @errp to error_prepend(), to avoid the above issue, add missing ERRP_GUARD() at the beginning of this function.

This is not optimal in some cases (e.g. memory spanning multiple NUMA nodes) because the memory objects are initialized in series. Allow the initialization to occur in parallel (asynchronously).

2024-01-04cpus: check running not RUN_STATE_RUNNINGSteve Sistare1-1/+1
When a vm transitions from running to suspended, runstate notifiers are not called, so the notifiers still think the vm is running. Hence, when we call vm_start to restore the suspended state, we call vm_state_notify with running=1. However, some notifiers check for RUN_STATE_RUNNING. They must check the running boolean instead.

Introduce an iommufd object which allows the interaction with the host /dev/iommu device. The /dev/iommu can have been already pre-opened outside of qemu, in which case the fd can be passed directly along with the iommufd object: This allows the iommufd object to be shared accross several subsystems (VFIO, VDPA, ...). For example, libvirt would open the /dev/iommu once. If no fd is passed along with the iommufd object, the /dev/iommu is opened by the qemu code.

2023-10-20migration: simplify blockersSteve Sistare1-8/+2
Modify migrate_add_blocker and migrate_del_blocker to take an Error ** reason. This allows migration to own the Error object, so that if an error occurs in migrate_add_blocker, migration code can free the Error and clear the client handle, simplifying client code. It also simplifies the migrate_del_blocker call site. In addition, this is a pre-requisite for a proposed future patch that would add a mode argument to migration requests to support live update, and maintain a list of blockers for each mode. A blocker may apply to a single mode or to multiple modes, and passing Error** will allow one Error object to be registered for multiple modes. No functional change.

2023-09-19backends/hostmem-file: Add "rom" property to support VM templating with R/O ↵David Hildenbrand1-1/+58
files For now, "share=off,readonly=on" would always result in us opening the file R/O and mmap'ing the opened file MAP_PRIVATE R/O -- effectively turning it into ROM. Especially for VM templating, "share=off" is a common use case. However, that use case is impossible with files that lack write permissions, because "share=off,readonly=on" will not give us writable RAM. The sole user of ROM via memory-backend-file are R/O NVDIMMs, but as we have users (Kata Containers) that rely on the existing behavior -- malicious VMs should not be able to consume COW memory for R/O NVDIMMs -- we cannot change the semantics of "share=off,readonly=on" So let's add a new "rom" property with on/off/auto values. "auto" is the default and what most people will use: for historical reasons, to not change the old semantics, it defaults to the value of the "readonly" property. For VM templating, one can now use: -object memory-backend-file,share=off,readonly=on,rom=off,... But we'll disallow: -object memory-backend-file,share=on,readonly=on,rom=off,... because we would otherwise get an error when trying to mmap the R/O file shared and writable. An explicit error message is cleaner. We will also disallow for now: -object memory-backend-file,share=off,readonly=off,rom=on,... -object memory-backend-file,share=on,readonly=off,rom=on,... It's not harmful, but also not really required for now. Alternatives that were abandoned: * Make "unarmed=on" for the NVDIMM set the memory region container readonly. We would still see a change of ROM->RAM and possibly run into memslot limits with vhost-user. Further, there might be use cases for "unarmed=on" that should still allow writing to that memory (temporary files, system RAM, ...). * Add a new "readonly=on/off/auto" parameter for NVDIMMs. Similar issues as with "unarmed=on". * Make "readonly" consume "on/off/file" instead of being a 'bool' type. This would slightly changes the behavior of the "readonly" parameter: values like true/false (as accepted by a 'bool'type) would no longer be accepted.

2023-09-19softmmu/physmem: Distinguish between file access mode and mmap protectionDavid Hildenbrand1-2/+2
There is a difference between how we open a file and how we mmap it, and we want to support writable private mappings of readonly files. Let's define RAM_READONLY and RAM_READONLY_FD flags, to replace the single "readonly" parameter for file-related functions. In memory_region_init_ram_from_fd() and memory_region_init_ram_from_file(), initialize mr->readonly based on the new RAM_READONLY flag. While at it, add some RAM_* flags we missed to add to the list of accepted flags in the documentation of some functions. No change in functionality intended. We'll make use of both flags next and start setting them independently for memory-backend-file.
