0808aef86d accel/qaic: Deprecate ->size field from attach slice IOCTL structure
->size in struct qaic_attach_slice_hdr is redundant since we have BO handle
and its size can be retrieved from base BO structure.

e5fba1ada1 Revert "drm: Introduce solid fill DRM plane property"
This reverts commit 85863a4e16.

Although the Solid Fill planes patchset got all reviews and
acknowledgements, it doesn't fulfill requirements for the new uABI. It
has neither corresponding open-source userspace implementation nor the
IGT tests coverage. Reverting this patchset until userspace obligations
are fulfilled.

drm/v3d: Create a CPU job extension for the copy performance query job
A CPU job is a type of job that performs operations that requires CPU

drm/v3d: Add a CPU job submission
Create a new type of job, a CPU job. A CPU job is a type of job that
performs operations that requires CPU intervention. The overall idea is
to use user extensions to enable different types of CPU job, allowing the
CPU job to perform different operations according to the type of user
extension. The user extension ID identify the type of CPU job that must
be dealt.

Having a CPU job is interesting for synchronization purposes as a CPU
job has a queue like any other V3D job and can be synchoronized by the
multisync extension.

Pull vfs fixes from Christian Brauner:

 - Avoid calling back into LSMs from vfs_getattr_nosec() calls.

   IMA used to query inode properties accessing raw inode fields without
   dedicated helpers. That was finally fixed a few releases ago by
   forcing IMA to use vfs_getattr_nosec() helpers.

   The goal of the vfs_getattr_nosec() helper is to query for attributes
   without calling into the LSM layer which would be quite problematic
   because incredibly IMA is called from __fput()...

     __fput()
       -> ima_file_free()

   What it does is to call back into the filesystem to update the file's
   IMA xattr. Querying the inode without using vfs_getattr_nosec() meant
   that IMA didn't handle stacking filesystems such as overlayfs
   correctly. So the switch to vfs_getattr_nosec() is quite correct. But
   the switch to vfs_getattr_nosec() revealed another bug when used on
   stacking filesystems:

     __fput()
       -> ima_file_free()
          -> vfs_getattr_nosec()
             -> i_op->getattr::ovl_getattr()
                -> vfs_getattr()
                   -> i_op->getattr::$WHATEVER_UNDERLYING_FS_getattr()
                      -> security_inode_getattr() # calls back into LSMs

   Now, if that __fput() happens from task_work_run() of an exiting task
   current->fs and various other pointer could already be NULL. So
   anything in the LSM layer relying on that not being NULL would be
   quite surprised.

   Fix that by passing the information that this is a security request
   through to the stacking filesystem by adding a new internal
   ATT_GETATTR_NOSEC flag. Now the callchain becomes:

     __fput()
       -> ima_file_free()
          -> vfs_getattr_nosec()
             -> i_op->getattr::ovl_getattr()
                -> if (AT_GETATTR_NOSEC)
                          vfs_getattr_nosec()
                   else
                          vfs_getattr()
                   -> i_op->getattr::$WHATEVER_UNDERLYING_FS_getattr()

 - Fix a bug introduced with the iov_iter rework from last cycle.

   This broke /proc/kcore by copying too much and without the correct
   offset.

 - Add a missing NULL check when allocating the root inode in
   autofs_fill_super().

 - Fix stable writes for multi-device filesystems (xfs, btrfs etc) and
   the block device pseudo filesystem.

   Stable writes used to be a superblock flag only, making it a per
   filesystem property. Add an additional AS_STABLE_WRITES mapping flag
   to allow for fine-grained control.

 - Ensure that offset_iterate_dir() returns 0 after reaching the end of
   a directory so it adheres to getdents() convention.

drm: Introduce DRM_CLIENT_CAP_CURSOR_PLANE_HOTSPOT
Virtualized drivers place additional restrictions on the cursor plane
which breaks the contract of universal planes. To allow atomic
modesettings with virtualized drivers the clients need to advertise
that they're capable of dealing with those extra restrictions.

To do that introduce DRM_CLIENT_CAP_CURSOR_PLANE_HOTSPOT which
lets DRM know that the client is aware of and capable of dealing with
the extra restrictions on the virtual cursor plane.

Setting this option to true makes DRM expose the cursor plane on
virtualized drivers. The userspace is expected to set the hotspots
and handle mouse events on that plane.

4b4af74ab9 drm: allow DRM_MODE_PAGE_FLIP_ASYNC for atomic commits
If the driver supports it, allow user-space to supply the
DRM_MODE_PAGE_FLIP_ASYNC flag to request an async page-flip.
Set drm_crtc_state.async_flip accordingly.

Document that drivers will reject atomic commits if an async
flip isn't possible. This allows user-space to fall back to
something else. For instance, Xorg falls back to a blit.
Another option is to wait as close to the next vblank as
possible before performing the page-flip to reduce latency.

8a924db2d7 fs: Pass AT_GETATTR_NOSEC flag to getattr interface function
When vfs_getattr_nosec() calls a filesystem's getattr interface function
then the 'nosec' should propagate into this function so that
vfs_getattr_nosec() can again be called from the filesystem's gettattr
rather than vfs_getattr(). The latter would add unnecessary security
checks that the initial vfs_getattr_nosec() call wanted to avoid.
Therefore, introduce the getattr flag GETATTR_NOSEC and allow to pass
with the new getattr_flags parameter to the getattr interface function.
In overlayfs and ecryptfs use this flag to determine which one of the
two functions to call.

In a recent code change introduced to IMA vfs_getattr_nosec() ended up
calling vfs_getattr() in overlayfs, which in turn called
security_inode_getattr() on an exiting process that did not have
current->fs set anymore, which then caused a kernel NULL pointer
dereference. With this change the call to security_inode_getattr() can
be avoided, thus avoiding the NULL pointer dereference.

7add80126b drm/uapi: add explicit virtgpu context debug name
There are two problems with the current method of determining the
virtio-gpu debug name.

1) TASK_COMM_LEN is defined to be 16 bytes only, and this is a
   Linux kernel idiom (see PR_SET_NAME + PR_GET_NAME). Though,
   Android/FreeBSD get around this via setprogname(..)/getprogname(..)
   in libc.

   On Android, names longer than 16 bytes are common.  For example,
   one often encounters a program like "com.android.systemui".

   The virtio-gpu spec allows the debug name to be up to 64 bytes, so
   ideally userspace should be able to set debug names up to 64 bytes.

2) The current implementation determines the debug name using whatever
   task initiated virtgpu.  This is could be a "RenderThread" of a
   larger program, when we actually want to propagate the debug name
   of the program.

To fix these issues, add a new CONTEXT_INIT param that allows userspace
to set the debug name when creating a context.

It takes a null-terminated C-string as the param value. The length of the
string (excluding the terminator) **should** be <= 64 bytes.  Otherwise,
the debug_name will be truncated to 64 bytes.

d393315244 btrfs: make OWNER_REF_KEY type value smallest among inline refs
BTRFS_EXTENT_OWNER_REF_KEY is the type of simple quotas extent owner
refs. This special inline ref goes in front of all other inline refs.

In general, inline refs have a required sorted order s.t. type never
decreases (among other requirements). This was recently reified into a
tree-checker and fsck rule, which broke simple quotas. To be fair,
though, in a sense, the new owner ref item had also violated that not
yet fully enforced requirement.

This fix brings the owner ref item into compliance with the requirement
that inline ref type never decrease.

btrfs/301 exercises this behavior and should pass again with this fix.

48d45fac39 accel/ivpu: Remove support for uncached buffers
Usages of DRM_IVPU_BO_UNCACHED should be replaced by DRM_IVPU_BO_WC.
There is no functional benefit from DRM_IVPU_BO_UNCACHED if these
buffers are never mapped to host VM.

This allows to cut the buffer handling code in the kernel driver
by half.

Usage of DRM_IVPU_BO_UNCACHED buffers was removed from user-space
driver and will not be part of first UMD release.

Pull unified attestation reporting from Dan Williams:
 "In an ideal world there would be a cross-vendor standard attestation
  report format for confidential guests along with a common device
  definition to act as the transport.

  In the real world the situation ended up with multiple platform
  vendors inventing their own attestation report formats with the
  SEV-SNP implementation being a first mover to define a custom
  sev-guest character device and corresponding ioctl(). Later, this
  configfs-tsm proposal intercepted an attempt to add a tdx-guest
  character device and a corresponding new ioctl(). It also anticipated
  ARM and RISC-V showing up with more chardevs and more ioctls().

  The proposal takes for granted that Linux tolerates the vendor report
  format differentiation until a standard arrives. From talking with
  folks involved, it sounds like that standardization work is unlikely
  to resolve anytime soon. It also takes the position that kernfs ABIs
  are easier to maintain than ioctl(). The result is a shared configfs
  mechanism to return per-vendor report-blobs with the option to later
  support a standard when that arrives.

  Part of the goal here also is to get the community into the
  "uncomfortable, but beneficial to the long term maintainability of the
  kernel" state of talking to each other about their differentiation and
  opportunities to collaborate. Think of this like the device-driver
  equivalent of the common memory-management infrastructure for
  confidential-computing being built up in KVM.

  As for establishing an "upstream path for cross-vendor
  confidential-computing device driver infrastructure" this is something
  I want to discuss at Plumbers. At present, the multiple vendor
  proposals for assigning devices to confidential computing VMs likely
  needs a new dedicated repository and maintainer team, but that is a
  discussion for v6.8.

  For now, Greg and Thomas have acked this approach and this is passing
  is AMD, Intel, and Google tests.

  Summary:

   - Introduce configfs-tsm as a shared ABI for confidential computing
     attestation reports

   - Convert sev-guest to additionally support configfs-tsm alongside
     its vendor specific ioctl()

   - Added signed attestation report retrieval to the tdx-guest driver
     forgoing a new vendor specific ioctl()

   - Misc cleanups and a new __free() annotation for kvfree()"

2c40c1c6ad USB/Thunderbolt changes for 6.7-rc1
Here is the "big" set of USB and Thunderbolt changes for 6.7-rc1.
 Nothing really major in here, just lots of constant development for new
 hardware.  Included in here are:
   - Thunderbolt (i.e. USB4) fixes for reported issues and support for
     new hardware types and devices
   - USB typec additions of new drivers and cleanups for some existing
     ones
   - xhci cleanups and expanded tracing support and some platform
     specific updates
   - USB "La Jolla Cove Adapter (LJCA)" support added, and the gpio, spi,
     and i2c drivers for that type of device (all acked by the respective
     subsystem maintainers.)
   - lots of USB gadget driver updates and cleanups
   - new USB dwc3 platforms supported, as well as other dwc3 fixes and
     cleanups
   - USB chipidea driver updates
   - other smaller driver cleanups and additions, full details in the
     shortlog
 
 All of these have been in the linux-next tree for a while with no
 reported problems, EXCEPT for some merge conflicts that you will run
 into in your tree.  2 of them are in device-tree files, which will be
 trivial to resolve (accept both sides), and the last in the
 drivers/gpio/gpio-ljca.c file, in the remove callback, resolution should
 be pretty trivial (take the version in this branch), see here:
 	https://lore.kernel.org/all/20231016134159.11d8f849@canb.auug.org.au/
 for details, or I can provide a resolved merge point if needed.

Pull landlock updates from Mickaël Salaün:
 "A Landlock ruleset can now handle two new access rights:
  LANDLOCK_ACCESS_NET_BIND_TCP and LANDLOCK_ACCESS_NET_CONNECT_TCP. When
  handled, the related actions are denied unless explicitly allowed by a
  Landlock network rule for a specific port.

  The related patch series has been reviewed for almost two years, it
  has evolved a lot and we now have reached a decent design, code and
  testing. The refactored kernel code and the new test helpers also
  bring the foundation to support more network protocols.

  Test coverage for security/landlock is 92.4% of 710 lines according to
  gcc/gcov-13, and it was 93.1% of 597 lines before this series. The
  decrease in coverage is due to code refactoring to make the ruleset
  management more generic (i.e. dealing with inodes and ports) that also
  added new WARN_ON_ONCE() checks not possible to test from user space.

  syzkaller has been updated accordingly [4], and such patched instance
  (tailored to Landlock) has been running for a month, covering all the
  new network-related code [5]"

31e5f934ff Tracing updates for v6.7:
- Remove eventfs_file descriptor
 
   This is the biggest change, and the second part of making eventfs
   create its files dynamically.
 
   In 6.6 the first part was added, and that maintained a one to one
   mapping between eventfs meta descriptors and the directories and
   file inodes and dentries that were dynamically created. The
   directories were represented by a eventfs_inode and the files
   were represented by a eventfs_file.
 
   In v6.7 the eventfs_file is removed. As all events have the same
   directory make up (sched_switch has an "enable", "id", "format",
   etc files), the handing of what files are underneath each leaf
   eventfs directory is moved back to the tracing subsystem via a
   callback. When a event is added to the eventfs, it registers
   an array of evenfs_entry's. These hold the names of the files and
   the callbacks to call when the file is referenced. The callback gets
   the name so that the same callback may be used by multiple files.
   The callback then supplies the filesystem_operations structure needed
   to create this file.
 
   This has brought the memory footprint of creating multiple eventfs
   instances down by 2 megs each!
 
 - User events now has persistent events that are not associated
   to a single processes. These are privileged events that hang around
   even if no process is attached to them.
 
 - Clean up of seq_buf.
   There's talk about using seq_buf more to replace strscpy() and friends.
   But this also requires some minor modifications of seq_buf to be
   able to do this.
 
 - Expand instance ring buffers individually
   Currently if boot up creates an instance, and a trace event is
   enabled on that instance, the ring buffer for that instance and the
   top level ring buffer are expanded (1.4 MB per CPU). This wastes
   memory as this happens when nothing is using the top level instance.
 
 - Other minor clean ups and fixes.

3b511278b6 accel/qaic: Support for 0 resize slice execution in BO
Add support to partially execute a slice which is resized to zero.
Executing a zero size slice in a BO should mean that there is no DMA
transfers involved but you should still configure doorbell and semaphores.

For example consider a BO of size 18K and it is sliced into 3 6K slices
and user calls partial execute ioctl with resize as 10K.
slice 0 - size is 6k and offset is 0, so resize of 10K will not cut short
          this slice hence we send the entire slice for execution.
slice 1 - size is 6k and offset is 6k, so resize of 10K will cut short this
          slice and only the first 4k should be DMA along with configuring
          doorbell and semaphores.
slice 2 - size is 6k and offset is 12k, so resize of 10k will cut short
          this slice and no DMA transfer would be involved but we should
          would configure doorbell and semaphores.

This change begs to change the behavior of 0 resize. Currently, 0 resize
partial execute ioctl behaves exactly like execute ioctl i.e. no resize.
After this patch all the slice in BO should behave exactly like slice 2 in
above example.

Refactor copy_partial_exec_reqs() to make it more readable and less
complex.

 "Many singleton patches against the MM code. The patch series which are
  included in this merge do the following:

   - Kemeng Shi has contributed some compation maintenance work in the
     series 'Fixes and cleanups to compaction'

   - Joel Fernandes has a patchset ('Optimize mremap during mutual
     alignment within PMD') which fixes an obscure issue with mremap()'s
     pagetable handling during a subsequent exec(), based upon an
     implementation which Linus suggested

   - More DAMON/DAMOS maintenance and feature work from SeongJae Park i
     the following patch series:

* Generalized infrastructure for 'writable' ID registers, effectively
   allowing userspace to opt-out of certain vCPU features for its guest
 
 * Optimization for vSGI injection, opportunistically compressing MPIDR
   to vCPU mapping into a table
 
 * Improvements to KVM's PMU emulation, allowing userspace to select
   the number of PMCs available to a VM
 
 * Guest support for memory operation instructions (FEAT_MOPS)
 
 * Cleanups to handling feature flags in KVM_ARM_VCPU_INIT, squashing
   bugs and getting rid of useless code
 
 * Changes to the way the SMCCC filter is constructed, avoiding wasted
   memory allocations when not in use
 
 * Load the stage-2 MMU context at vcpu_load() for VHE systems, reducing
   the overhead of errata mitigations
 
 * Miscellaneous kernel and selftest fixes
 
 LoongArch:
 
 * New architecture.  The hardware uses the same model as x86, s390
   and RISC-V, where guest/host mode is orthogonal to supervisor/user
   mode.  The virtualization extensions are very similar to MIPS,
   therefore the code also has some similarities but it's been cleaned
   up to avoid some of the historical bogosities that are found in
   arch/mips.  The kernel emulates MMU, timer and CSR accesses, while
   interrupt controllers are only emulated in userspace, at least for
   now.
 
 RISC-V:
 
 * Support for the Smstateen and Zicond extensions
 
 * Support for virtualizing senvcfg
 
 * Support for virtualized SBI debug console (DBCN)
 
 S390:
 
 * Nested page table management can be monitored through tracepoints
   and statistics
 
 x86:
 
 * Fix incorrect handling of VMX posted interrupt descriptor in KVM_SET_LAPIC,
   which could result in a dropped timer IRQ
 
 * Avoid WARN on systems with Intel IPI virtualization
 
 * Add CONFIG_KVM_MAX_NR_VCPUS, to allow supporting up to 4096 vCPUs without
   forcing more common use cases to eat the extra memory overhead.
 
 * Add virtualization support for AMD SRSO mitigation (IBPB_BRTYPE and
   SBPB, aka Selective Branch Predictor Barrier).
 
 * Fix a bug where restoring a vCPU snapshot that was taken within 1 second of
   creating the original vCPU would cause KVM to try to synchronize the vCPU's
   TSC and thus clobber the correct TSC being set by userspace.
 
 * Compute guest wall clock using a single TSC read to avoid generating an
   inaccurate time, e.g. if the vCPU is preempted between multiple TSC reads.
 
 * "Virtualize" HWCR.TscFreqSel to make Linux guests happy, which complain
   about a "Firmware Bug" if the bit isn't set for select F/M/S combos.
   Likewise "virtualize" (ignore) MSR_AMD64_TW_CFG to appease Windows Server
   2022.
 
 * Don't apply side effects to Hyper-V's synthetic timer on writes from
   userspace to fix an issue where the auto-enable behavior can trigger
   spurious interrupts, i.e. do auto-enabling only for guest writes.
 
 * Remove an unnecessary kick of all vCPUs when synchronizing the dirty log
   without PML enabled.
 
 * Advertise "support" for non-serializing FS/GS base MSR writes as appropriate.
 
 * Harden the fast page fault path to guard against encountering an invalid
   root when walking SPTEs.
 
 * Omit "struct kvm_vcpu_xen" entirely when CONFIG_KVM_XEN=n.
 
 * Use the fast path directly from the timer callback when delivering Xen
   timer events, instead of waiting for the next iteration of the run loop.
   This was not done so far because previously proposed code had races,
   but now care is taken to stop the hrtimer at critical points such as
   restarting the timer or saving the timer information for userspace.
 
 * Follow the lead of upstream Xen and ignore the VCPU_SSHOTTMR_future flag.
 
 * Optimize injection of PMU interrupts that are simultaneous with NMIs.
 
 * Usual handful of fixes for typos and other warts.
 
 x86 - MTRR/PAT fixes and optimizations:
 
 * Clean up code that deals with honoring guest MTRRs when the VM has
   non-coherent DMA and host MTRRs are ignored, i.e. EPT is enabled.
 
 * Zap EPT entries when non-coherent DMA assignment stops/start to prevent
   using stale entries with the wrong memtype.
 
 * Don't ignore guest PAT for CR0.CD=1 && KVM_X86_QUIRK_CD_NW_CLEARED=y.
   This was done as a workaround for virtual machine BIOSes that did not
   bother to clear CR0.CD (because ancient KVM/QEMU did not bother to
   set it, in turn), and there's zero reason to extend the quirk to
   also ignore guest PAT.
 
 x86 - SEV fixes:
 
 * Report KVM_EXIT_SHUTDOWN instead of EINVAL if KVM intercepts SHUTDOWN while
   running an SEV-ES guest.
 
 * Clean up the recognition of emulation failures on SEV guests, when KVM would
   like to "skip" the instruction but it had already been partially emulated.
   This makes it possible to drop a hack that second guessed the (insufficient)
   information provided by the emulator, and just do the right thing.
