2022-07-08LoadPin: Enable loading from trusted dm-verity devicesMatthias Kaehlcke1-0/+22
Extend LoadPin to allow loading of kernel files from trusted dm-verity [1] devices. This change adds the concept of trusted verity devices to LoadPin. LoadPin maintains a list of root digests of verity devices it considers trusted. Userspace can populate this list through an ioctl on the new LoadPin securityfs entry 'dm-verity'. The ioctl receives a file descriptor of a file with verity digests as parameter. Verity reads the digests from this file after confirming that the file is located on the pinned root. The digest file must contain one digest per line. The list of trusted digests can only be set up once, which is typically done at boot time. When a kernel file is read LoadPin first checks (as usual) whether the file is located on the pinned root, if so the file can be loaded. Otherwise, if the verity extension is enabled, LoadPin determines whether the file is located on a verity backed device and whether the root digest of that device is in the list of trusted digests. The file can be loaded if the verity device has a trusted root digest. Background: As of now LoadPin restricts loading of kernel files to a single pinned filesystem, typically the rootfs. This works for many systems, however it can result in a bloated rootfs (and OTA updates) on platforms where multiple boards with different hardware configurations use the same rootfs image. Especially when 'optional' files are large it may be preferable to download/install them only when they are actually needed by a given board. Chrome OS uses Downloadable Content (DLC) [2] to deploy certain 'packages' at runtime. As an example a DLC package could contain firmware for a peripheral that is not present on all boards. DLCs use dm-verity to verify the integrity of the DLC content.

2022-07-08dm: Add verity helpers for LoadPinMatthias Kaehlcke1-0/+27
LoadPin limits loading of kernel modules, firmware and certain other files to a 'pinned' file system (typically a read-only rootfs). To provide more flexibility LoadPin is being extended to also allow loading these files from trusted dm-verity devices. For that purpose LoadPin can be provided with a list of verity root digests that it should consider as trusted. Add a bunch of helpers to allow LoadPin to check whether a DM device is a trusted verity device. The new functions broadly fall in two categories: those that need access to verity internals (like the root digest), and the 'glue' between LoadPin and verity. The new file dm-verity-loadpin.c contains the glue functions.

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into driver-core-next Sudeep writes: cacheinfo and arch_topology updates for v5.20 These are updates to fix some discrepancies we have in the CPU topology parsing from the device tree /cpu-map node and the divergence from the behaviour on a ACPI enabled platform. The expectation is that both DT and ACPI enabled systems must present consistent view of the CPU topology. The current assignment of generated cluster count as the physical package identifier for each CPU is wrong. The device tree bindings for CPU topology supports sockets to infer the socket or physical package identifier for a given CPU. It is now being made use of you address the issue. These updates also assigns the cluster identifier as parsed from the device tree cluster nodes within /cpu-map without support for nesting of the clusters as there are no such reported/known platforms. In order to be on par with ACPI PPTT physical package/socket support, these updates also include support for socket nodes in /cpu-map. The only exception is that the last level cache id information can be inferred from the same ACPI PPTT while we need to parse CPU cache nodes in the device tree. The cacheinfo changes here is to enable the re-use of the cacheinfo to detect the cache attributes for all the CPU quite early even before the scondardaries are booted so that the information can be used to build the schedular domains especially the last level cache(LLC). * tag 'arch-cache-topo-5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: (21 commits) ACPI: Remove the unused find_acpi_cpu_cache_topology() arch_topology: Warn that topology for nested clusters is not supported arch_topology: Add support for parsing sockets in /cpu-map arch_topology: Set cluster identifier in each core/thread from /cpu-map arch_topology: Limit span of cpu_clustergroup_mask() arch_topology: Don't set cluster identifier as physical package identifier arch_topology: Avoid parsing through all the CPUs once a outlier CPU is found arch_topology: Check for non-negative value rather than -1 for IDs validity arch_topology: Set thread sibling cpumask only within the cluster arch_topology: Drop LLC identifier stash from the CPU topology arm64: topology: Remove redundant setting of llc_id in CPU topology arch_topology: Use the last level cache information from the cacheinfo arch_topology: Add support to parse and detect cache attributes cacheinfo: Align checks in cache_shared_cpu_map_{setup,remove} for readability cacheinfo: Use cache identifiers to check if the caches are shared if available cacheinfo: Allow early detection and population of cache attributes cacheinfo: Add support to check if last level cache(LLC) is valid or shared cacheinfo: Move cache_leaves_are_shared out of CONFIG_OF cacheinfo: Add helper to access any cache index for a given CPU cacheinfo: Use of_cpu_device_node_get instead cpu_dev->of_node ...

2022-07-08usb: misc: Add onboard_usb_hub driverMatthias Kaehlcke1-0/+18
The main issue this driver addresses is that a USB hub needs to be powered before it can be discovered. For discrete onboard hubs (an example for such a hub is the Realtek RTS5411) this is often solved by supplying the hub with an 'always-on' regulator, which is kind of a hack. Some onboard hubs may require further initialization steps, like changing the state of a GPIO or enabling a clock, which requires even more hacks. This driver creates a platform device representing the hub which performs the necessary initialization. Currently it only supports switching on a single regulator, support for multiple regulators or other actions can be added as needed. Different initialization sequences can be supported based on the compatible string. Besides performing the initialization the driver can be configured to power the hub off during system suspend. This can help to extend battery life on battery powered devices which have no requirements to keep the hub powered during suspend. The driver can also be configured to leave the hub powered when a wakeup capable USB device is connected when suspending, and power it off otherwise. Technically the driver consists of two drivers, the platform driver described above and a very thin USB driver that subclasses the generic driver. The purpose of this driver is to provide the platform driver with the USB devices corresponding to the hub(s) (a hub controller may provide multiple 'logical' hubs, e.g. one to support USB 2.0 and another for USB 3.x).

The trace event sock_exceed_buf_limit saves the prot->sysctl_mem pointer and then dereferences it in the TP_printk() portion. This is unsafe as the TP_printk() portion is executed at the time the buffer is read. That is, it can be seconds, minutes, days, months, even years later. If the proto is freed, then this dereference will can also lead to a kernel crash. Instead, save the sysctl_mem array into the ring buffer and have the TP_printk() reference that instead. This is the proper and safe way to read pointers in trace events.

2022-07-07vfio/ccw: Remove UUID from s390 debug logMichael Kawano1-5/+0
As vfio-ccw devices are created/destroyed, the uuid of the associated mdevs that are recorded in $S390DBF/vfio_ccw_msg/sprintf get lost. This is because a pointer to the UUID is stored instead of the UUID itself, and that memory may have been repurposed if/when the logs are examined. The result is usually garbage UUID data in the logs, though there is an outside chance of an oops happening here. Simply remove the UUID from the traces, as the subchannel number will provide useful configuration information for problem determination, and is stored directly into the log instead of a pointer. As we were the only consumer of mdev_uuid(), remove that too.

2022-07-07mm: kasan: Skip unpoisoning of user pagesCatalin Marinas1-1/+1
Commit c275c5c6d50a ("kasan: disable freed user page poisoning with HW tags") added __GFP_SKIP_KASAN_POISON to GFP_HIGHUSER_MOVABLE. A similar argument can be made about unpoisoning, so also add __GFP_SKIP_KASAN_UNPOISON to user pages. To ensure the user page is still accessible via page_address() without a kasan fault, reset the page->flags tag. With the above changes, there is no need for the arm64 tag_clear_highpage() to reset the page->flags tag.
