2024-07-05tests/tcg: Adjust variable defintion from cc-optionRichard Henderson
Define the variable to the compiler flag used, not "y". This avoids replication of the compiler flag itself.

2024-07-05tests/docker: Specify --userns keep-id for PodmanAkihiko Odaki
Previously we are always specifying -u $(UID) to match the UID in the container with one outside. This causes a problem with rootless Podman. Rootless Podman remaps user IDs in the container to ones controllable for the current user outside. The -u option instructs Podman to use a specified UID in the container but does not affect the UID remapping. Therefore, the UID in the container can be remapped to some other UID outside the container. This can make the access to bind-mounted volumes fail because the remapped UID mismatches with the owner of the directories. Replace -u $(UID) with --userns keep-id, which fixes the UID remapping. This change is limited to Podman because Docker does not support --userns keep-id.

2024-07-05hw/core: ensure kernel_end never gets used undefinedAlex Bennée
Really the problem here is the return values of fit_load_[kernel|fdt]() are a little all over the place. However we don't want to somehow get through not having set kernel_end and having it just be random unused data.

2024-07-05testing: restore some testing for i686Alex Bennée
The commit 4f9a8315e6 (gitlab-ci.d/crossbuilds: Drop the i386 system emulation job) was a little too aggressive dropping testing for 32 bit system builds. Partially revert but using the debian-i686 cross build images this time as fedora has deprecated the 32 bit stuff. As the SEV breakage gets in the way and its TCG issues we want to catch I've added --disable-kvm to the build.

Drop features that are listed as "BitMask" in the PPR and currently not supported by AMD processors. The only ones that may become useful in the future are TSC deadline timer and x2APIC, everything else is not needed for SEV-SNP guests (e.g. VIRT_SSBD) or would require processor support (e.g. TSC_ADJUST). This allows running SEV-SNP guests with "-cpu host". Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2024-07-03hw/pci: Replace -1 with UINT32_MAX for romsizeAkihiko Odaki
romsize is an uint32_t variable. Specifying -1 as an uint32_t value is obscure way to denote UINT32_MAX. Worse, if int is wider than 32-bit, it will change the behavior of a construct like the following: romsize = -1; if (romsize != -1) { ... } When -1 is assigned to romsize, -1 will be implicitly casted into uint32_t, resulting in UINT32_MAX. On contrary, when evaluating romsize != -1, romsize will be casted into int, and it will be a comparison of UINT32_MAX and -1, and result in false. Replace -1 with UINT32_MAX for statements involving the variable to clarify the intent and prevent potential breakage.

2024-07-03virtio-iommu: Clear IOMMUDevice when VFIO device is unpluggedCédric Le Goater
When a VFIO device is hoplugged in a VM using virtio-iommu, IOMMUPciBus and IOMMUDevice cache entries are created in the .get_address_space() handler of the machine IOMMU device. However, these entries are never destroyed, not even when the VFIO device is detached from the machine. This can lead to an assert if the device is reattached again. When reattached, the .get_address_space() handler reuses an IOMMUDevice entry allocated when the VFIO device was first attached. virtio_iommu_set_host_iova_ranges() is called later on from the .set_iommu_device() handler an fails with an assert on 'probe_done' because the device appears to have been already probed when this is not the case. The IOMMUDevice entry is allocated in pci_device_iommu_address_space() called from under vfio_realize(), the VFIO PCI realize handler. Since pci_device_unset_iommu_device() is called from vfio_exitfn(), a sub function of the PCIDevice unrealize() handler, it seems that the .unset_iommu_device() handler is the best place to release resources allocated at realize time. Clear the IOMMUDevice cache entry there to fix hotplug.

2024-07-03hw/arm/virt-acpi-build: Fix id_count in build_iort_id_mappingNicolin Chen
It's observed that Linux kernel booting with the VM reports a "conflicting mapping for input ID" FW_BUG. The IORT doc defines "Number of IDs" to be "the number of IDs in the range minus one", while virt-acpi-build.c simply stores the number of IDs in the id_count without the "minus one". Meanwhile, some of the callers pass in a 0xFFFF following the spec. So, this is a mismatch between the function and its callers. Fix build_iort_id_mapping() by internally subtracting one from the pass-in @id_count. Accordingly make sure that all existing callers pass in a value without the "minus one", i.e. change all 0xFFFFs to 0x10000s. Also, add a few lines of comments to highlight this change along with the referencing document for this build_iort_id_mapping().

2024-07-03hw/i386/fw_cfg: Add etc/e820 to fw_cfg lateDavid Woodhouse
In e820_add_entry() the e820_table is reallocated with g_renew() to make space for a new entry. However, fw_cfg_arch_create() just uses the existing e820_table pointer. This leads to a use-after-free if anything adds a new entry after fw_cfg is set up. Shift the addition of the etc/e820 file to the machine done notifier, via a new fw_cfg_add_e820() function. Also make e820_table private and use an e820_get_table() accessor function for it, which sets a flag that will trigger an assert() for any *later* attempts to add to the table. Make e820_add_entry() return void, as most callers don't check for error anyway.

2024-07-03hw/virtio: Fix the de-initialization of vhost-user devicesThomas Huth
The unrealize functions of the various vhost-user devices are calling the corresponding vhost_*_set_status() functions with a status of 0 to shut down the device correctly. Now these vhost_*_set_status() functions all follow this scheme: bool should_start = virtio_device_should_start(vdev, status); if (vhost_dev_is_started(&vvc->vhost_dev) == should_start) { return; } if (should_start) { /* ... do the initialization stuff ... */ } else { /* ... do the cleanup stuff ... */ } The problem here is virtio_device_should_start(vdev, 0) currently always returns "true" since it internally only looks at vdev->started instead of looking at the "status" parameter. Thus once the device got started once, virtio_device_should_start() always returns true and thus the vhost_*_set_status() functions return early, without ever doing any clean-up when being called with status == 0. This causes e.g. problems when trying to hot-plug and hot-unplug a vhost user devices multiple times since the de-initialization step is completely skipped during the unplug operation. This bug has been introduced in commit 9f6bcfd99f ("hw/virtio: move vm_running check to virtio_device_started") which replaced should_start = status & VIRTIO_CONFIG_S_DRIVER_OK; with should_start = virtio_device_started(vdev, status); which later got replaced by virtio_device_should_start(). This blocked the possibility to set should_start to false in case the status flag VIRTIO_CONFIG_S_DRIVER_OK was not set. Fix it by adjusting the virtio_device_should_start() function to only consider the status flag instead of vdev->started. Since this function is only used in the various vhost_*_set_status() functions for exactly the same purpose, it should be fine to fix it in this central place there without any risk to change the behavior of other code.

2024-07-03hostmem: add a new memory backend based on POSIX shm_open()Stefano Garzarella
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.
