* esp: ensure in-flight SCSI requests are always cancelledMark Cave-Ayland2021-11-021-5/+5
| | | | | | | | | | | | | | | | | | | | | | There is currently a check in esp_select() to cancel any in-flight SCSI requests to ensure that issuing multiple select commands without continuing through the rest of the ESP state machine ignores all but the last SCSI request. This is also enforced through the addition of assert()s in esp_transfer_data() and scsi_read_data(). The get_cmd() function does not call esp_select() when TC == 0 which means it is possible for a fuzzer to trigger these assert()s by sending a select command when TC == 0 immediately after a valid SCSI CDB has been submitted. Since esp_select() is only called from get_cmd(), hoist the check to cancel in-flight SCSI requests from esp_select() into get_cmd() to ensure it is always called when executing a select command to initiate a new SCSI request.

* hw/i386: fix vmmouse registrationPavel Dovgalyuk2021-11-021-0/+1
| | | | | | | | | | | | | | According to the logic of vmmouse_update_handler function, vmmouse should be registered as an event handler when it's status is zero. vmmouse_read_id resets the status but does not register the handler. This patch adds vmmouse registration and activation when status is reset.

* watchdog: remove select_watchdog_actionPaolo Bonzini2021-11-021-14/+0
| | | | | | | | | | | | | Instead of invoking select_watchdog_action from both HMP and command line, go directly from HMP to QMP and use QemuOpts as the intermediary for the command line. This makes -watchdog-action explicitly a shortcut for "-action watchdog", so that "-watchdog-action" and "-action watchdog" override each other based on the position on the command line; previously, "-action watchdog" always won.

* hw/i386: Rename default_bus_bypass_iommuJean-Philippe Brucker2021-11-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Since commit d8fb7d0969d5 ("vl: switch -M parsing to keyval"), machine parameter definitions cannot use underscores, because keyval_dashify() transforms them to dashes and the parser doesn't find the parameter. This affects option default_bus_bypass_iommu which was introduced in the same release: $ qemu-system-x86_64 -M q35,default_bus_bypass_iommu=on qemu-system-x86_64: Property 'pc-q35-6.1-machine.default-bus-bypass-iommu' not found Rename the parameter to "default-bus-bypass-iommu". Passing "default_bus_bypass_iommu" is still valid since the underscore are transformed automatically.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MSI-X structures of some devices and other non-MSI-X structures may be in the same BAR. They may share one host page, especially in the case of large page granularity, such as 64K. For example, MSIX-Table size of 82599 NIC is 0x30 and the offset in Bar 3(size 64KB) is 0x0. vfio_listener_region_add() will be called to map the remaining range (0x30-0xffff). If host page size is 64KB, it will return early at 'int128_ge((int128_make64(iova), llend))' without any message. Let's add a trace point to inform users like commit 5c08600547c0 ("vfio: Use a trace point when a RAM section cannot be DMA mapped") did.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We can expand MemoryRegions of sub-page MMIO BARs in vfio_pci_write_config() to improve IO performance for some devices. However, the MemoryRegions of destination VM are not expanded any more after live migration. Because their addresses have been updated in vmstate_load_state() (vfio_pci_load_config) and vfio_sub_page_bar_update_mapping() will not be called. This may result in poor performance after live migration. So iterate BARs in vfio_pci_load_config() and try to update sub-page BARs.

* | machine: remove the done notifier for dynamic sysbus device type checkDamien Hedde2021-11-011-27/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we check sysbus device types during device creation, we can remove the check in the machine init done notifier. This was the only thing done by this notifier, so we remove the whole sysbus_notifier structure of the MachineState. Note: This notifier was checking all /peripheral and /peripheral-anon sysbus devices. Now we only check those added by -device cli option or device_add qmp command when handling the command/option. So if there are some devices added in one of these containers manually (eg in machine C code), these will not be checked anymore. This use case does not seem to appear apart from hw/xen/xen-legacy-backend.c (it uses qdev_set_id() and in this case, not for a sysbus device, so it's ok).

* hw/char/sh_serial: Do not abort on invalid accessBALATON Zoltan2021-10-301-9/+10
| | | | | | | | | | | | | | | | Replace fprintf with qemu_log_mask LOG_GUEST_ERROR as the intention is to handle valid accesses in these functions so if we get to these errors then it's an invalid access. Do not abort as that would allow the guest to crash QEMU and the practice in other devices is to not do that just log and ignore the invalid access. While at it also simplify the complex bit ops to check if a return value was set which can be done much simpler and clearer.
