e229b429bb Char/Misc driver patches for 5.12-rc1
Here is the large set of char/misc/whatever driver subsystem updates for
 5.12-rc1.  Over time it seems like this tree is collecting more and more
 tiny driver subsystems in one place, making it easier for those
 maintainers, which is why this is getting larger.
 
 Included in here are:
 	- coresight driver updates
 	- habannalabs driver updates
 	- virtual acrn driver addition (proper acks from the x86
 	  maintainers)
 	- broadcom misc driver addition
 	- speakup driver updates
 	- soundwire driver updates
 	- fpga driver updates
 	- amba driver updates
 	- mei driver updates
 	- vfio driver updates
 	- greybus driver updates
 	- nvmeem driver updates
 	- phy driver updates
 	- mhi driver updates
 	- interconnect driver udpates
 	- fsl-mc bus driver updates
 	- random driver fix
 	- some small misc driver updates (rtsx, pvpanic, etc.)
 
 All of these have been in linux-next for a while, with the only reported
 issue being a merge conflict in include/linux/mod_devicetable.h that you
 will hit in your tree due to the dfl_device_id addition from the fpga
 subsystem in here.  The resolution should be simple.

89e0eb8c13 xfs: restore speculative_cow_prealloc_lifetime sysctl
In commit 9669f51de5c0 I tried to get rid of the undocumented cow gc
lifetime knob.  The knob's function was never documented and it now
doesn't really have a function since eof and cow gc have been
consolidated.

Regrettably, xfs/231 relies on it and regresses on for-next.  I did not
succeed at getting far enough through fstests patch review for the fixup
to land in time.

Restore the sysctl knob, document what it did (does?), put it on the
deprecation schedule, and rip out a redundant function.

Fixes: 9669f51de5c0 ("xfs: consolidate the eofblocks and cowblocks workers")

7ac1161c27 Driver core / debugfs update for 5.12-rc1
Here is the "big" driver core and debugfs update for 5.12-rc1
 
 This set of driver core patches caused a bunch of problems in linux-next
 for the past few weeks, when Saravana tried to set fw_devlink=on as the
 default functionality.  This caused a number of systems to stop booting,
 and lots of bugs were fixed in this area for almost all of the reported
 systems, but this option is not ready to be turned on just yet for the
 default operation based on this testing, so I've reverted that change at
 the very end so we don't have to worry about regressions in 5.12.  We
 will try to turn this on for 5.13 if testing goes better over the next
 few months.
 
 Other than the fixes caused by the fw_devlink testing in here, there's
 not much more:
 	- debugfs fixes for invalid input into debugfs_lookup()
 	- kerneldoc cleanups
 	- warn message if platform drivers return an error on their
 	  remove callback (a futile effort, but good to catch).
 
 All of these have been in linux-next for a while now, and the
 regressions have gone away with the revert of the fw_devlink change.

825d150875 cxl for 5.12
Introduce an initial driver for CXL 2.0 Type-3 Memory Devices. CXL is
 Compute Express Link which released the 2.0 specification in November.
 The Linux relevant changes in CXL 2.0 are support for an OS to
 dynamically assign address space to memory devices, support for
 switches, persistent memory, and hotplug. A Type-3 Memory Device is a
 PCI enumerated device presenting the CXL Memory Device Class Code and
 implementing the CXL.mem protocol. CXL.mem allows device to advertise
 CPU and I/O coherent memory to the system, i.e. typical "System RAM" and
 "Persistent Memory" in Linux /proc/iomem terms.
 
 In addition to the CXL.mem fast path there is an administrative command
 hardware mailbox interface for maintenance and provisioning. It is this
 command interface that is the focus of the initial driver. With this
 driver a CXL device that is mapped by the BIOS can be administered by
 Linux. Linux support for CXL PMEM and dynamic CXL address space
 management are to be implemented post v5.12.

Pull keyring updates from David Howells:
 "Here's a set of minor keyrings fixes/cleanups that I've collected from
  various people for the upcoming merge window.

  A couple of them might, in theory, be visible to userspace:

   - Make blacklist_vet_description() reject uppercase letters as they
     don't match the all-lowercase hex string generated for a blacklist
     search.

     This may want reconsideration in the future, but, currently, you
     can't add to the blacklist keyring from userspace and the only
     source of blacklist keys generates lowercase descriptions.

   - Fix blacklist_init() to use a new KEY_ALLOC_* flag to indicate that
     it wants KEY_FLAG_KEEP to be set rather than passing KEY_FLAG_KEEP
     into keyring_alloc() as KEY_FLAG_KEEP isn't a valid alloc flag.

     This isn't currently a problem as the blacklist keyring isn't
     currently writable by userspace.

  The rest of the patches are cleanups and I don't think they should
  have any visible effect"

Merge tag 'idmapped-mounts-v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux

Pull idmapped mounts from Christian Brauner:
 "This introduces idmapped mounts which has been in the making for some
  time. Simply put, different mounts can expose the same file or
  directory with different ownership. This initial implementation comes
  with ports for fat, ext4 and with Christoph's port for xfs with more
  filesystems being actively worked on by independent people and
  maintainers.

  Idmapping mounts handle a wide range of long standing use-cases. Here
  are just a few:

   - Idmapped mounts make it possible to easily share files between
     multiple users or multiple machines especially in complex
     scenarios. For example, idmapped mounts will be used in the
     implementation of portable home directories in
     systemd-homed.service(8) where they allow users to move their home
     directory to an external storage device and use it on multiple
     computers where they are assigned different uids and gids. This
     effectively makes it possible to assign random uids and gids at
     login time.

   - It is possible to share files from the host with unprivileged
     containers without having to change ownership permanently through
     chown(2).

   - It is possible to idmap a container's rootfs and without having to
     mangle every file. For example, Chromebooks use it to share the
     user's Download folder with their unprivileged containers in their
     Linux subsystem.

   - It is possible to share files between containers with
     non-overlapping idmappings.

   - Filesystem that lack a proper concept of ownership such as fat can
     use idmapped mounts to implement discretionary access (DAC)
     permission checking.

   - They allow users to efficiently changing ownership on a per-mount
     basis without having to (recursively) chown(2) all files. In
     contrast to chown (2) changing ownership of large sets of files is
     instantenous with idmapped mounts. This is especially useful when
     ownership of a whole root filesystem of a virtual machine or
     container is changed. With idmapped mounts a single syscall
     mount_setattr syscall will be sufficient to change the ownership of
     all files.

   - Idmapped mounts always take the current ownership into account as
     idmappings specify what a given uid or gid is supposed to be mapped
     to. This contrasts with the chown(2) syscall which cannot by itself
     take the current ownership of the files it changes into account. It
     simply changes the ownership to the specified uid and gid. This is
     especially problematic when recursively chown(2)ing a large set of
     files which is commong with the aforementioned portable home
     directory and container and vm scenario.

   - Idmapped mounts allow to change ownership locally, restricting it
     to specific mounts, and temporarily as the ownership changes only
     apply as long as the mount exists.

  Several userspace projects have either already put up patches and
  pull-requests for this feature or will do so should you decide to pull
  this:

   - systemd: In a wide variety of scenarios but especially right away
     in their implementation of portable home directories.

         https://systemd.io/HOME_DIRECTORY/

   - container runtimes: containerd, runC, LXD:To share data between
     host and unprivileged containers, unprivileged and privileged
     containers, etc. The pull request for idmapped mounts support in
     containerd, the default Kubernetes runtime is already up for quite
     a while now: https://github.com/containerd/containerd/pull/4734

   - The virtio-fs developers and several users have expressed interest
     in using this feature with virtual machines once virtio-fs is
     ported.

   - ChromeOS: Sharing host-directories with unprivileged containers.

  I've tightly synced with all those projects and all of those listed
  here have also expressed their need/desire for this feature on the
  mailing list. For more info on how people use this there's a bunch of
  talks about this too. Here's just two recent ones:

      https://www.cncf.io/wp-content/uploads/2020/12/Rootless-Containers-in-Gitpod.pdf
      https://fosdem.org/2021/schedule/event/containers_idmap/

  This comes with an extensive xfstests suite covering both ext4 and
  xfs:

      https://git.kernel.org/brauner/xfstests-dev/h/idmapped_mounts

  It covers truncation, creation, opening, xattrs, vfscaps, setid
  execution, setgid inheritance and more both with idmapped and
  non-idmapped mounts. It already helped to discover an unrelated xfs
  setgid inheritance bug which has since been fixed in mainline. It will
  be sent for inclusion with the xfstests project should you decide to
  merge this.

  In order to support per-mount idmappings vfsmounts are marked with
  user namespaces. The idmapping of the user namespace will be used to
  map the ids of vfs objects when they are accessed through that mount.
  By default all vfsmounts are marked with the initial user namespace.
  The initial user namespace is used to indicate that a mount is not
  idmapped. All operations behave as before and this is verified in the
  testsuite.

  Based on prior discussions we want to attach the whole user namespace
  and not just a dedicated idmapping struct. This allows us to reuse all
  the helpers that already exist for dealing with idmappings instead of
  introducing a whole new range of helpers. In addition, if we decide in
  the future that we are confident enough to enable unprivileged users
  to setup idmapped mounts the permission checking can take into account
  whether the caller is privileged in the user namespace the mount is
  currently marked with.

  The user namespace the mount will be marked with can be specified by
  passing a file descriptor refering to the user namespace as an
  argument to the new mount_setattr() syscall together with the new
  MOUNT_ATTR_IDMAP flag. The system call follows the openat2() pattern
  of extensibility.

  The following conditions must be met in order to create an idmapped
  mount:

   - The caller must currently have the CAP_SYS_ADMIN capability in the
     user namespace the underlying filesystem has been mounted in.

   - The underlying filesystem must support idmapped mounts.

   - The mount must not already be idmapped. This also implies that the
     idmapping of a mount cannot be altered once it has been idmapped.

   - The mount must be a detached/anonymous mount, i.e. it must have
     been created by calling open_tree() with the OPEN_TREE_CLONE flag
     and it must not already have been visible in the filesystem.

  The last two points guarantee easier semantics for userspace and the
  kernel and make the implementation significantly simpler.

  By default vfsmounts are marked with the initial user namespace and no
  behavioral or performance changes are observed.

  The manpage with a detailed description can be found here:

      1d7b902e28

  In order to support idmapped mounts, filesystems need to be changed
  and mark themselves with the FS_ALLOW_IDMAP flag in fs_flags. The
  patches to convert individual filesystem are not very large or
  complicated overall as can be seen from the included fat, ext4, and
  xfs ports. Patches for other filesystems are actively worked on and
  will be sent out separately. The xfstestsuite can be used to verify
  that port has been done correctly.

  The mount_setattr() syscall is motivated independent of the idmapped
  mounts patches and it's been around since July 2019. One of the most
  valuable features of the new mount api is the ability to perform
  mounts based on file descriptors only.

  Together with the lookup restrictions available in the openat2()
  RESOLVE_* flag namespace which we added in v5.6 this is the first time
  we are close to hardened and race-free (e.g. symlinks) mounting and
  path resolution.

  While userspace has started porting to the new mount api to mount
  proper filesystems and create new bind-mounts it is currently not
  possible to change mount options of an already existing bind mount in
  the new mount api since the mount_setattr() syscall is missing.

  With the addition of the mount_setattr() syscall we remove this last
  restriction and userspace can now fully port to the new mount api,
  covering every use-case the old mount api could. We also add the
  crucial ability to recursively change mount options for a whole mount
  tree, both removing and adding mount options at the same time. This
  syscall has been requested multiple times by various people and
  projects.

  There is a simple tool available at

      https://github.com/brauner/mount-idmapped

  that allows to create idmapped mounts so people can play with this
  patch series. I'll add support for the regular mount binary should you
  decide to pull this in the following weeks:

  Here's an example to a simple idmapped mount of another user's home
  directory:

820c872795 Input: cros-ec-keyb - expose function row physical map to userspace
The top-row keys in a keyboard usually have dual functionalities.
E.g. A function key "F1" is also an action key "Browser back".

Therefore, when an application receives an action key code from
a top-row key press, the application needs to know how to correlate
the action key code with the function key code and do the conversion
whenever necessary.

Since the userpace already knows the key scanlines (row/column)
associated with a received key code. Essentially, the userspace only
needs a mapping between the key row/column and the matching physical
location in the top row.

So, enhance the cros-ec-keyb driver to create such a mapping
and expose it to userspace in the form of a function_row_physmap
attribute. The attribute would be a space separated ordered list of
row/column codes for the keys in the function row, in a left-to-right
order.

The attribute will only be present when the device has a custom design
for the top-row keys.

11481d6b57 dt-bindings: add Canaan boards compatible strings
Introduce the file riscv/canaan.yaml to document compatible strings
related to the Canaan Kendryte K210 SoC. The compatible string
"canaan,kendryte-k210" used to indicate the use of this SoC to the
early SoC init code is added. This new file also defines the compatible
strings of all supported boards based on this SoC.

c958423470 Tracing updates for 5.12
- Update to the way irqs and preemption is tracked via the trace event PC field
 
  - Fix handling of unregistering event failing due to allocate memory.
    This is only triggered by failure injection, as it is pretty much guaranteed
    to have less than a page allocation succeed.
 
  - Do not show the useless "filter" or "enable" files for the "ftrace" trace
    system, as they have no effect on doing anything.
 
  - Add a warning if kprobes are registered more than once.
 
  - Synthetic events now have their fields parsed by semicolons.
    Old formats without semicolons will still work, but new features will
    require them.
 
  - New option to allow trace events to show %p without hashing in trace file.
    The trace file can only be read by root, and reading the raw event buffer
    did not have any pointers hashed, so this does not expose anything new.
 
  - New directory in tools called tools/tracing, where a new tool that reads
    sequential latency reports from the ftrace latency tracers.
 
  - Other minor fixes and cleanups.

163ba35ff3 doc: use KCFLAGS instead of EXTRA_CFLAGS to pass flags from command line
You should use KCFLAGS to pass additional compiler flags from the
command line. Using EXTRA_CFLAGS is wrong.

EXTRA_CFLAGS is supposed to specify flags applied only to the current
Makefile (and now deprecated in favor of ccflags-y).

It is still used in arch/mips/kvm/Makefile (and possibly in external
modules too). Passing EXTRA_CFLAGS from the command line overwrites
it and breaks the build.

I also fixed drivers/gpu/drm/tilcdc/Makefile because commit 816175dd1fd7
("drivers/gpu/drm/tilcdc: Makefile, only -Werror when no -W* in
EXTRA_CFLAGS") was based on the same misunderstanding.
