tty: actually undefine superseded ASYNC flags

2021-05-14T07:44:22Z

[ Upstream commit d09845e98a05850a8094ea8fd6dd09a8e6824fff ] Some kernel-internal ASYNC flags have been superseded by tty-port flags and should no longer be used by kernel drivers. Fix the misspelled "__KERNEL__" compile guards which failed their sole purpose to break out-of-tree drivers that have not yet been updated.

usb: webcam: Invalid size of Processing Unit Descriptor

2021-05-11T12:04:05Z

[ Upstream commit 6a154ec9ef6762c774cd2b50215c7a8f0f08a862 ] According with USB Device Class Definition for Video Device the Processing Unit Descriptor bLength should be 12 (10 + bmControlSize), but it has 11. Invalid length caused that Processing Unit Descriptor Test Video form CV tool failed. To fix this issue patch adds bmVideoStandards into uvc_processing_unit_descriptor structure. The bmVideoStandards field was added in UVC 1.1 and it wasn't part of UVC 1.0a.

vfio iommu: Add dma available capability

2021-01-17T13:05:30Z

[ Upstream commit 7d6e1329652ed971d1b6e0e7bea66fba5044e271 ] The following functional changes were needed for backport: - vfio_iommu_type1_get_info doesn't exist, call vfio_iommu_dma_avail_build_caps from vfio_iommu_type1_ioctl. - As further fallout from this, vfio_iommu_dma_avail_build_caps must acquire and release the iommu mutex lock. To do so, the return value is stored in a local variable as in vfio_iommu_iova_build_caps. Upstream commit description: Commit 492855939bdb ("vfio/type1: Limit DMA mappings per container") added the ability to limit the number of memory backed DMA mappings. However on s390x, when lazy mapping is in use, we use a very large number of concurrent mappings. Let's provide the current allowable number of DMA mappings to userspace via the IOMMU info chain so that userspace can take appropriate mitigation.

fscrypt: remove kernel-internal constants from UAPI header

2021-01-06T13:48:35Z

commit 3ceb6543e9cf6ed87cc1fbc6f23ca2db903564cd upstream. There isn't really any valid reason to use __FSCRYPT_MODE_MAX or FSCRYPT_POLICY_FLAGS_VALID in a userspace program. These constants are only meant to be used by the kernel internally, and they are defined in the UAPI header next to the mode numbers and flags only so that kernel developers don't forget to update them when adding new modes or flags. In https://lkml.kernel.org/r/20201005074133.1958633-2-satyat@google.com there was an example of someone wanting to use __FSCRYPT_MODE_MAX in a user program, and it was wrong because the program would have broken if __FSCRYPT_MODE_MAX were ever increased. So having this definition available is harmful. FSCRYPT_POLICY_FLAGS_VALID has the same problem. So, remove these definitions from the UAPI header. Replace FSCRYPT_POLICY_FLAGS_VALID with just listing the valid flags explicitly in the one kernel function that needs it. Move __FSCRYPT_MODE_MAX to fscrypt_private.h, remove the double underscores (which were only present to discourage use by userspace), and add a BUILD_BUG_ON() and comments to (hopefully) ensure it is kept in sync. Keep the old name FS_POLICY_FLAGS_VALID, since it's been around for longer and there's a greater chance that removing it would break source compatibility with some program. Indeed, mtd-utils is using it in an #ifdef, and removing it would introduce compiler warnings (about FS_POLICY_FLAGS_PAD_* being redefined) into the mtd-utils build. However, reduce its value to 0x07 so that it only includes the flags with old names (the ones present before Linux 5.4), and try to make it clear that it's now "frozen" and no new flags should be added to it.
