Pull DSA and IAA accelerator mis-alignment fix from Arjan van de Ven:
 "The DSA (memory copy/zero/etc) and IAA (compression) accelerators in
  the Sapphire Rapids and Emerald Rapids SOCs turn out to have a bug
  that has security implications.

  Both of these accelerators work by the application submitting a 64
  byte command to the device; this command contains an opcode as well as
  the virtual address of the return value that the device will update on
  completion... and a set of opcode specific values.

  In a typical scenario a ring 3 application mmaps the device file and
  uses the ENQCMD or MOVDIR64 instructions (which are variations of a 64
  byte atomic write) on this mmap'd memory region to directly submit
  commands to a device hardware.

  The return value as specified in the command, is supposed to be 32 (or
  64) bytes aligned in memory, and generally the hardware checks and
  enforces this alignment.

  However in testing it has been found that there are conditions
  (controlled by the submitter) where this enforcement does not
  happen... which makes it possible for the return value to span a page
  boundary. And this is where it goes wrong - the accelerators will
  perform the virtual to physical address lookup on the first of the two
  pages, but end up continue writing to the next consecutive physical
  (host) page rather than the consecutive virtual page. In addition, the
  device will end up in a hung state on such unaligned write of the
  return value.

  This patch series has the proposed software side solution consisting
  of three parts:

   - Don't allow these two PCI devices to be assigned to VM guests (we
     cannot trust a VM guest to behave correctly and not cause this
     condition)

   - Don't allow ring 3 applications to set up the mmap unless they have
     CAP_SYS_RAWIO permissions. This makes it no longer possible for
     non-root applications to directly submit commands to the
     accelerator

   - Add a write() method to the device so that an application can
     submit its commands to the kernel driver, which performs the needed
     sanity checks before submitting it to the hardware.

  This switch from mmap to write is an incompatible interface change to
  non-root userspace, but we have not found a way to avoid this. All
  software we know of uses a small set of accessor libraries for these
  accelerators, for which libqpl and libdml (on github) are the most
  common. As part of the security release, updated versions of these
  libraries will be released that transparently fall back to write().

  Intel has assigned CVE-2024-21823 to this hardware issue"

Pull Rust updates from Miguel Ojeda:
 "The most notable change is the drop of the 'alloc' in-tree fork. This
  is nicely reflected in the diffstat as a ~10k lines drop. In turn,
  this makes the version upgrades way simpler and smaller in the future,
  e.g. the latest one in commit 56f64b37 ("rust: upgrade to Rust
  1.78.0").

  More importantly, this increases the chances that a newer compiler
  version just works, which in turn means supporting several compiler
  versions is easier now. Thus we will look into finally setting a
  minimum version in the near future.

  Toolchain and infrastructure:

   - Upgrade to Rust 1.78.0

     This time around, due to how the kernel and Rust schedules have
     aligned, there are two upgrades in fact. These allow us to remove
     one more unstable feature ('offset_of') from the list, among other
     improvements

   - Drop 'alloc' in-tree fork of the standard library crate, which
     means all the unstable features used by 'alloc' (~30 language ones,
     ~60 library ones) are not a concern anymore

   - Support DWARFv5 via the '-Zdwarf-version' flag

   - Support zlib and zstd debuginfo compression via the
     '-Zdebuginfo-compression' flag

  'kernel' crate:

   - Support allocation flags ('GFP_*'), particularly in 'Box' (via
     'BoxExt'), 'Vec' (via 'VecExt'), 'Arc' and 'UniqueArc', as well as
     in the 'init' module APIs

   - Remove usage of the 'allocator_api' unstable feature

   - Remove 'try_' prefix in allocation APIs' names

   - Add 'VecExt' (an extension trait) to be able to drop the 'alloc'
     fork

   - Add the '{make,to}_{upper,lower}case()' methods to 'CStr'/'CString'

   - Add the 'as_ptr' method to 'ThisModule'

   - Add the 'from_raw' method to 'ArcBorrow'

   - Add the 'into_unique_or_drop' method to 'Arc'

   - Display column number in the 'dbg!' macro output by applying the
     equivalent change done to the standard library one

   - Migrate 'Work' to '#[pin_data]' thanks to the changes in the
     'macros' crate, which allows to remove an unsafe call in its 'new'
     associated function

   - Prevent namespacing issues when using the '[try_][pin_]init!'
     macros by changing the generated name of guard variables

   - Make the 'get' method in 'Opaque' const

   - Implement the 'Default' trait for 'LockClassKey'

   - Remove unneeded 'kernel::prelude' imports from doctests

   - Remove redundant imports

  'macros' crate:

   - Add 'decl_generics' to 'parse_generics()' to support default
     values, and use that to allow them in '#[pin_data]'

  Helpers:

   - Trivial English grammar fix

  Documentation:

   - Add section on Rust Kselftests to the 'Testing' document

   - Expand the 'Abstractions vs. bindings' section of the 'General
     Information' document"

Pull hardening updates from Kees Cook:
 "The bulk of the changes here are related to refactoring and expanding
  the KUnit tests for string helper and fortify behavior.

  Some trivial strncpy replacements in fs/ were carried in my tree. Also
  some fixes to SCSI string handling were carried in my tree since the
  helper for those was introduce here. Beyond that, just little fixes
  all around: objtool getting confused about LKDTM+KCFI, preparing for
  future refactors (constification of sysctl tables, additional
  __counted_by annotations), a Clang UBSAN+i386 crash fix, and adding
  more options in the hardening.config Kconfig fragment.

  Summary:

   - selftests: Add str*cmp tests (Ivan Orlov)

   - __counted_by: provide UAPI for _le/_be variants (Erick Archer)

   - Various strncpy deprecation refactors (Justin Stitt)

   - stackleak: Use a copy of soon-to-be-const sysctl table (Thomas
     Weißschuh)

   - UBSAN: Work around i386 -regparm=3 bug with Clang prior to
     version 19

   - Provide helper to deal with non-NUL-terminated string copying

   - SCSI: Fix older string copying bugs (with new helper)

   - selftests: Consolidate string helper behavioral tests

   - selftests: add memcpy() fortify tests

Pull io_uring updates from Jens Axboe:

 - Greatly improve send zerocopy performance, by enabling coalescing of
   sent buffers.

   MSG_ZEROCOPY already does this with send(2) and sendmsg(2), but the
   io_uring side did not. In local testing, the crossover point for send
   zerocopy being faster is now around 3000 byte packets, and it
   performs better than the sync syscall variants as well.

   This feature relies on a shared branch with net-next, which was
   pulled into both branches.

 - Unification of how async preparation is done across opcodes.

   Previously, opcodes that required extra memory for async retry would
   allocate that as needed, using on-stack state until that was the
   case. If async retry was needed, the on-stack state was adjusted
   appropriately for a retry and then copied to the allocated memory.

   This led to some fragile and ugly code, particularly for read/write
   handling, and made storage retries more difficult than they needed to
   be. Allocate the memory upfront, as it's cheap from our pools, and
   use that state consistently both initially and also from the retry
   side.

 - Move away from using remap_pfn_range() for mapping the rings.

   This is really not the right interface to use and can cause lifetime
   issues or leaks. Additionally, it means the ring sq/cq arrays need to
   be physically contigious, which can cause problems in production with
   larger rings when services are restarted, as memory can be very
   fragmented at that point.

   Move to using vm_insert_page(s) for the ring sq/cq arrays, and apply
   the same treatment to mapped ring provided buffers. This also helps
   unify the code we have dealing with allocating and mapping memory.

   Hard to see in the diffstat as we're adding a few features as well,
   but this kills about ~400 lines of code from the codebase as well.

 - Add support for bundles for send/recv.

   When used with provided buffers, bundles support sending or receiving
   more than one buffer at the time, improving the efficiency by only
   needing to call into the networking stack once for multiple sends or
   receives.

 - Tweaks for our accept operations, supporting both a DONTWAIT flag for
   skipping poll arm and retry if we can, and a POLLFIRST flag that the
   application can use to skip the initial accept attempt and rely
   purely on poll for triggering the operation. Both of these have
   identical flags on the receive side already.

 - Make the task_work ctx locking unconditional.

   We had various code paths here that would do a mix of lock/trylock
   and set the task_work state to whether or not it was locked. All of
   that goes away, we lock it unconditionally and get rid of the state
   flag indicating whether it's locked or not.

   The state struct still exists as an empty type, can go away in the
   future.

 - Add support for specifying NOP completion values, allowing it to be
   used for error handling testing.

 - Use set/test bit for io-wq worker flags. Not strictly needed, but
   also doesn't hurt and helps silence a KCSAN warning.

 - Cleanups for io-wq locking and work assignments, closing a tiny race
   where cancelations would not be able to find the work item reliably.

Pull netfs updates from Christian Brauner:
 "This reworks the netfslib writeback implementation so that pages read
  from the cache are written to the cache through ->writepages(),
  thereby allowing the fscache page flag to be retired.

  The reworking also:

   - builds on top of the new writeback_iter() infrastructure

   - makes it possible to use vectored write RPCs as discontiguous
     streams of pages can be accommodated

   - makes it easier to do simultaneous content crypto and stream
     division

   - provides support for retrying writes and re-dividing a stream

   - replaces the ->launder_folio() op, so that ->writepages() is used
     instead

   - uses mempools to allocate the netfs_io_request and
     netfs_io_subrequest structs to avoid allocation failure in the
     writeback path

  Some code that uses the fscache page flag is retained for
  compatibility purposes with nfs and ceph. The code is switched to
  using the synonymous private_2 label instead and marked with
  deprecation comments.

Pull slab updates from Vlastimil Babka:
 "This time it's mostly random cleanups and fixes, with two performance
  fixes that might have significant impact, but limited to systems
  experiencing particular bad corner case scenarios rather than general
  performance improvements.

  The memcg hook changes are going through the mm tree due to
  dependencies.

   - Prevent stalls when reading /proc/slabinfo (Jianfeng Wang)

     This fixes the long-standing problem that can happen with workloads
     that have alloc/free patterns resulting in many partially used
     slabs (in e.g. dentry cache). Reading /proc/slabinfo will traverse
     the long partial slab list under spinlock with disabled irqs and
     thus can stall other processes or even trigger the lockup
     detection. The traversal is only done to count free objects so that
     <active_objs> column can be reported along with <num_objs>.

     To avoid affecting fast paths with another shared counter
     (attempted in the past) or complex partial list traversal schemes
     that allow rescheduling, the chosen solution resorts to
     approximation - when the partial list is over 10000 slabs long, we
     will only traverse first 5000 slabs from head and tail each and use
     the average of those to estimate the whole list. Both head and tail
     are used as the slabs near head to tend to have more free objects
     than the slabs towards the tail.

     It is expected the approximation should not break existing
     /proc/slabinfo consumers. The <num_objs> field is still accurate
     and reflects the overall kmem_cache footprint. The <active_objs>
     was already imprecise due to cpu and percpu-partial slabs, so can't
     be relied upon to determine exact cache usage. The difference
     between <active_objs> and <num_objs> is mainly useful to determine
     the slab fragmentation, and that will be possible even with the

   - Prevent allocating many slabs when a NUMA node is full (Chen Jun)

     Currently, on NUMA systems with a node under significantly bigger
     pressure than other nodes, the fallback strategy may result in each
     kmalloc_node() that can't be safisfied from the preferred node, to
     allocate a new slab on a fallback node, and not reuse the slabs
     already on that node's partial list.

     This is now fixed and partial lists of fallback nodes are checked
     even for kmalloc_node() allocations. It's still preferred to
     allocate a new slab on the requested node before a fallback, but
     only with a GFP_NOWAIT attempt, which will fail quickly when the
     node is under a significant memory pressure.

Pull kcsan update from Paul McKenney:
 "Introduce __data_racy type qualifier

  This adds a __data_racy type qualifier that enables kernel developers
  to inform KCSAN that a given variable is a shared variable without
  needing to mark each and every access.

  This allows pre-KCSAN code to be correctly (if approximately)
  instrumented withh very little effort, and also provides people
  reading the code a clear indication that the variable is in fact
  shared.

  In addition, it permits incremental transition to per-access KCSAN
  marking, so that (for example) a given subsystem can be transitioned
  one variable at a time, while avoiding large numbers of KCSAN warnings
  during this transition"

Pull cmpxchg updates from Paul McKenney:
 "Provide one-byte and two-byte cmpxchg() support on sparc32, parisc,
  and csky

  This provides native one-byte and two-byte cmpxchg() support for
  sparc32 and parisc, courtesy of Al Viro. This support is provided by
  the same hashed-array-of-locks technique used for the other atomic
  operations provided for these two platforms.

  There is also emulated one-byte cmpxchg() support for csky using a new
  cmpxchg_emu_u8() function that uses a four-byte cmpxchg() to emulate
  the one-byte variant.

  Similar patches for emulation of one-byte cmpxchg() for arc, sh, and
  xtensa have not yet received maintainer acks, so they are slated for
  the v6.11 merge window"
