2022-06-28platform/x86: panasonic-laptop: filter out duplicate volume up/down/mute ↵Hans de Goede
keypresses On some Panasonic models the volume up/down/mute keypresses get reported both through the Panasonic ACPI HKEY interface as well as through the atkbd device. Filter out the atkbd scan-codes for these to avoid reporting presses twice. Note normally we would leave the filtering of these to userspace by mapping the scan-codes to KEY_UNKNOWN through /lib/udev/hwdb.d/60-keyboard.hwdb. However in this case that would cause regressions since we were filtering the Panasonic ACPI HKEY events before, so filter these in the kernel.

Change how acpi_video_handles_brightness_key_presses() determines if brightness key-presses are handled by the ACPI video driver to avoid vendor specific drivers/platform/x86 drivers filtering out their brightness key-presses even though they are the only ones reporting these presses.

2022-06-27vhost-vdpa: call vhost_vdpa_cleanup during the releaseStefano Garzarella
Before commit 3d5698793897 ("vhost-vdpa: introduce asid based IOTLB") we call vhost_vdpa_iotlb_free() during the release to clean all regions mapped in the iotlb. That commit removed vhost_vdpa_iotlb_free() and added vhost_vdpa_cleanup() to do some cleanup, including deleting all mappings, but we forgot to call it in vhost_vdpa_release(). This causes that if an application does not remove all mappings explicitly (or it crashes), the mappings remain in the iotlb and subsequent applications may fail if they map the same addresses. Calling vhost_vdpa_cleanup() also fixes a memory leak since we are not freeing `v->vdev.vqs` during the release from the same commit. Since vhost_vdpa_cleanup() calls vhost_dev_cleanup() we can remove its call from vhost_vdpa_release().

2022-06-27virtio_mmio: Restore guest page size on resumeStephan Gerhold
Virtio devices might lose their state when the VMM is restarted after a suspend to disk (hibernation) cycle. This means that the guest page size register must be restored for the virtio_mmio legacy interface, since otherwise the virtio queues are not functional. This is particularly problematic for QEMU that currently still defaults to using the legacy interface for virtio_mmio. Write the guest page size register again in virtio_mmio_restore() to make legacy virtio_mmio devices work correctly after hibernation.

2022-06-27virtio_mmio: Add missing PM calls to freeze/restoreStephan Gerhold
Most virtio drivers provide freeze/restore callbacks to finish up device usage before suspend and to reinitialize the virtio device after resume. However, these callbacks are currently only called when using virtio_pci. virtio_mmio does not have any PM ops defined. This causes problems for example after suspend to disk (hibernation), since the virtio devices might lose their state after the VMM is restarted. Calling virtio_device_freeze()/restore() ensures that the virtio devices are re-initialized correctly. Fix this by implementing the dev_pm_ops for virtio_mmio, similar to virtio_pci_common.

2022-06-27caif_virtio: fix race between virtio_device_ready() and ndo_open()Jason Wang
We currently depend on probe() calling virtio_device_ready() - which happens after netdev registration. Since ndo_open() can be called immediately after register_netdev, this means there exists a race between ndo_open() and virtio_device_ready(): the driver may start to use the device (e.g. TX) before DRIVER_OK which violates the spec. Fix this by switching to use register_netdevice() and protect the virtio_device_ready() with rtnl_lock() to make sure ndo_open() can only be called after virtio_device_ready().

2022-06-24USB: gadget: Fix double-free bug in raw_gadget driverAlan Stern
Re-reading a recently merged fix to the raw_gadget driver showed that it inadvertently introduced a double-free bug in a failure pathway. If raw_ioctl_init() encounters an error after the driver ID number has been allocated, it deallocates the ID number before returning. But when dev_free() runs later on, it will then try to deallocate the ID number a second time. Closely related to this issue is another error in the recent fix: The ID number is stored in the raw_dev structure before the code checks to see whether the structure has already been initialized, in which case the new ID number would overwrite the earlier value. The solution to both bugs is to keep the new ID number in a local variable, and store it in the raw_dev structure only after the check for prior initialization. No errors can occur after that point, so the double-free will never happen.

2022-06-24crypto: ccp - Fix device IRQ counting by using platform_irq_count()Tom Lendacky
The ccp driver loops through the platform device resources array to get the IRQ count for the device. With commit a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource from DT core"), the IRQ resources are no longer stored in the platform device resource array. As a result, the IRQ count is now always zero. This causes the driver to issue a second call to platform_get_irq(), which fails if the IRQ count is really 1, causing the loading of the driver to fail. Replace looping through the resources array to count the number of IRQs with a call to platform_irq_count().

2022-06-24virtio: disable notification hardening by defaultJason Wang
We try to harden virtio device notifications in 8b4ec69d7e09 ("virtio: harden vring IRQ"). It works with the assumption that the driver or core can properly call virtio_device_ready() at the right place. Unfortunately, this seems to be not true and uncover various bugs of the existing drivers, mainly the issue of using virtio_device_ready() incorrectly. So let's add a Kconfig option and disable it by default. It gives us time to fix the drivers and then we can consider re-enabling it.

2022-06-24virtio_ring : keep used_wrap_counter in vq->last_used_idxhuangjie.albert
the used_wrap_counter and the vq->last_used_idx may get out of sync if they are separate assignment,and interrupt might use an incorrect value to check for the used index. for example:OOB access ksoftirqd may consume the packet and it will call: virtnet_poll -->virtnet_receive -->virtqueue_get_buf_ctx -->virtqueue_get_buf_ctx_packed and in virtqueue_get_buf_ctx_packed: vq->last_used_idx += vq->packed.desc_state[id].num; if (unlikely(vq->last_used_idx >= vq->packed.vring.num)) { vq->last_used_idx -= vq->packed.vring.num; vq->packed.used_wrap_counter ^= 1; } if at the same time, there comes a vring interrupt,in vring_interrupt: we will call: vring_interrupt -->more_used -->more_used_packed -->is_used_desc_packed in is_used_desc_packed, the last_used_idx maybe >= vq->packed.vring.num. so this could case a memory out of bounds bug. this patch is to keep the used_wrap_counter in vq->last_used_idx so we can get the correct value to check for used index in interrupt. v3->v4: - use READ_ONCE/WRITE_ONCE to get/set vq->last_used_idx v2->v3: - add inline function to get used_wrap_counter and last_used - when use vq->last_used_idx, only read once if vq->last_used_idx is read twice, the values can be inconsistent. - use last_used_idx & ~(-(1 << VRING_PACKED_EVENT_F_WRAP_CTR)) to get the all bits below VRING_PACKED_EVENT_F_WRAP_CTR v1->v2: - reuse the VRING_PACKED_EVENT_F_WRAP_CTR - Remove parameter judgment in is_used_desc_packed, because it can't be illegal Signed-off-by: huangjie.albert <huangjie.albert@bytedance.com> Message-Id: <20220617020411.80367-1-huangjie.albert@bytedance.com> Signed-off-by: Michael S.
