The Designated Vendor-Specific Extended Capability (DVSEC Capability) is an optional Extended Capability that is permitted to be implemented by any PCI Express Function. This allows PCI Express component vendors to use the Extended Capability mechanism to expose vendor-specific registers that can be present in components by a variety of vendors. A DVSEC Capability structure can tell vendor-specific software which features a particular component supports. An example usage of DVSEC is Intel Platform Monitoring Technology (PMT) for enumerating and accessing hardware monitoring capabilities on a device. PMT encompasses three device monitoring features, Telemetry (device metrics), Watcher (sampling/tracing), and Crashlog. The DVSEC is used to discover these features and provide a BAR offset to their registers with the Intel vendor code. The current VFIO driver does not pass DVSEC capabilities to Virtual Machine (VM) which makes PMT not to work inside the virtual machine. This series adds DVSEC capability to user visible list to allow its use with VFIO. VFIO supports passing of Vendor Specific Extended Capability (VSEC) and raw write access to device. DVSEC also passed to VM in the same way as of VSEC. Signed-off-by:

Pull compute express link (cxl) fixes from Dan Williams: "Several fixes for driver startup regressions that landed during the merge window as well as some older bugs. The regressions were due to a lack of testing with what the CXL specification calls Restricted CXL Host (RCH) topologies compared to the testing with Virtual Host (VH) CXL topologies. A VH topology is typical PCIe while RCH topologies map CXL endpoints as Root Complex Integrated endpoints. The impact is some driver crashes on startup. This merge window also added compatibility for range registers (the mechanism that CXL 1.1 defined for mapping memory) to treat them like HDM decoders (the mechanism that CXL 2.0 defined for mapping Host-managed Device Memory). That work collided with the new region enumeration code that was tested with CXL 2.0 setups, and fails with crashes at startup. Lastly, the DOE (Data Object Exchange) implementation for retrieving an ACPI-like data table from CXL devices is being reworked for v6.4. Several fixes fell out of that work that are suitable for v6.3. All of this has been in linux-next for a while, and all reported issues [1] have been addressed. Summary: - Fix several issues with region enumeration in RCH topologies that can trigger crashes on driver startup or shutdown. - Fix CXL DVSEC range register compatibility versus region enumeration that leads to startup crashes - Fix CDAT endiannes handling - Fix multiple buffer handling boundary conditions - Fix Data Object Exchange (DOE) workqueue usage vs CONFIG_DEBUG_OBJECTS warn splats" Link: http://lore.kernel.org/r/20230405075704.33de8121@canb.auug.org.au [1] * tag 'cxl-fixes-6.3-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: cxl/hdm: Extend DVSEC range register emulation for region enumeration cxl/hdm: Limit emulation to the number of range registers cxl/region: Move coherence tracking into cxl_region_attach() cxl/region: Fix region setup/teardown for RCDs cxl/port: Fix find_cxl_root() for RCDs and simplify it cxl/hdm: Skip emulation when driver manages mem_enable cxl/hdm: Fix double allocation of @cxlhdm PCI/DOE: Fix memory leak with CONFIG_DEBUG_OBJECTS=y PCI/DOE: Silence WARN splat with CONFIG_DEBUG_OBJECTS=y cxl/pci: Handle excessive CDAT length cxl/pci: Handle truncated CDAT entries cxl/pci: Handle truncated CDAT header cxl/pci: Fix CDAT retrieval on big endian

Currently if disk_scan_partitions() failed, GD_NEED_PART_SCAN will still set, and partition scan will be proceed again when blkdev_get_by_dev() is called. However, this will cause a problem that re-assemble partitioned raid device will creat partition for underlying disk. Test procedure: mdadm -CR /dev/md0 -l 1 -n 2 /dev/sda /dev/sdb -e 1.0 sgdisk -n 0:0:+100MiB /dev/md0 blockdev --rereadpt /dev/sda blockdev --rereadpt /dev/sdb mdadm -S /dev/md0 mdadm -A /dev/md0 /dev/sda /dev/sdb Test result: underlying disk partition and raid partition can be observed at the same time Note that this can still happen in come corner cases that GD_NEED_PART_SCAN can be set for underlying disk while re-assemble raid device.

Syzkaller report a WARNING: "WARN_ON(!direct)" in modify_ftrace_direct(). Root cause is 'direct->addr' was changed from 'old_addr' to 'new_addr' but not restored if error happened on calling ftrace_modify_direct_caller(). Then it can no longer find 'direct' by that 'old_addr'. To fix it, restore 'direct->addr' to 'old_addr' explicitly in error path.

The alignment mask in swiotlb_do_find_slots() masks off the high bits which are not relevant for the alignment, so multiple requirements are combined with a bitwise OR rather than AND. In plain English, the stricter the alignment, the more bits must be set in iotlb_align_mask. Confusion may arise from the fact that the same variable is also used to mask off the offset within a swiotlb slot, which is achieved with a bitwise AND.

block size is one very key setting for block layer, and bad block size could panic kernel easily. Make sure that block size is set correctly. Meantime if ublk_validate_params() fails, clear ub->params so that disk is prevented from being added. Fixes: 71f28f31 ("ublk_drv: add io_uring based userspace block driver") Reported-and-tested-by:

Since SQE memory is shared with userspace, we should only be reading it once. We cannot read it multiple times, particularly when it's read once for validation and then read again for the actual use. ublk_ch_uring_cmd() is safe when called as a retry operation, as the memory backing is stable at that point. But for normal issue, we want to ensure that we only read ublksrv_io_cmd once. Wrap the function in a helper that reads the value into an on-stack copy of the struct.

Queue reset was moved out from __init_dma_rx_desc_rings() and __init_dma_tx_desc_rings() functions. Thus, the driver fails to transmit and receive packet after XDP prog setup.

When deleting the netns and recreating a new one while re-adding the veth interface, there is a small window of time during which the old veth interface has not yet been removed. This can cause the new addition to fail. To resolve this issue, we can either wait for a short while to ensure that the old veth interface is deleted, or we can specifically remove the veth interface.

Not all fec MDIO bus drivers support C45 mode transactions. The older fec hardware block in many ColdFire SoCs does not appear to support them, at least according to most of the different ColdFire SoC reference manuals. The bits used to generate C45 access on the iMX parts, in the OP field of the MMFR register, are documented as generating non-compliant MII frames (it is not documented as to exactly how they are non-compliant). Commit 8d03ad1a ("net: fec: Separate C22 and C45 transactions") means the fec driver will always register c45 MDIO read and write methods. During probe these will always be accessed now generating non-compliant MII accesses on ColdFire based devices. Add a quirk define, FEC_QUIRK_HAS_MDIO_C45, that can be used to distinguish silicon that supports MDIO C45 framing or not. Add this to all the existing iMX quirks, so they will be behave as they do now (*). (*) it seems that some iMX parts may not support C45 transactions either. The iMX25 and iMX50 Reference Manuals contain similar wording to the ColdFire Reference Manuals on this. Fixes: 8d03ad1a ("net: fec: Separate C22 and C45 transactions") Signed-off-by:
