Pull printk updates from Petr Mladek:

 - Stop synchronizing kernel log buffer readers by logbuf_lock. As a
   result, the access to the buffer is fully lockless now.

   Note that printk() itself still uses locks because it tries to flush
   the messages to the console immediately. Also the per-CPU temporary
   buffers are still there because they prevent infinite recursion and
   serialize backtraces from NMI. All this is going to change in the
   future.

 - kmsg_dump API rework and cleanup as a side effect of the logbuf_lock
   removal.

 - Make bstr_printf() aware that %pf and %pF formats could deference the
   given pointer.

 - fix buffer size for in-kernel disassembler for ebpf programs.

 - fix two memory leaks in zcrypt driver.

 - expose PCI device UID as index, including an indicator if the uid is

 - remove some oprofile leftovers.

 - improve stack unwinder tests.

 - don't use gcc atomic builtins anymore, just like all other
   architectures. Even though I'm sure the current code is ok, I totally
   dislike that s390 is the only architecture being special here;
   especially considering that there was a lengthly discussion about
   this topic and the outcome was not to use the builtins. Therefore
   open-code atomic ops again with inline assembly and switch to gcc
   builtins as soon as other architectures are doing.

 - couple of other changes to atomic and cmpxchg, and use
   atomic-instrumented.h for KASAN.

 - separate zbus creation, registration, and scanning in our PCI code
   which allows for cleaner and easier handling.

 - a rather large change to the vfio-ap code to fix circular locking
   dependencies when updating crypto masks.

 - move QAOB handling from qdio layer down to drivers.

 - add CRW inject facility to common I/O layer. This adds debugs files
   which allow to generate artificial events from user space for testing
   purposes.

 - increase SCLP console line length from 80 to 320 characters to avoid
   odd wrapped lines.

 - add protected virtualization guest and host indication files, which
   indicate either that a guest is running in pv mode or if the
   hypervisor is capable of starting pv guests.

   how one decodes insns in the kernel. Convert its users to it.

 - Rip out the dynamic NOP selection and simplify all the machinery
   around selecting NOPs. Use the simplified NOPs in objtool now too.

 - Add Xeon Sapphire Rapids to list of CPUs that support PPIN

 - Simplify the retpolines by folding the entire thing into an
   alternative now that objtool can handle alternatives with stack ops.
   Then, have objtool rewrite the call to the retpoline with the

It seems like Fedora 34 ends up enabling a few new gcc warnings, notably
"-Wstringop-overread" and "-Warray-parameter".

Both of them cause what seem to be valid warnings in the kernel, where
we have array size mismatches in function arguments (that are no longer
just silently converted to a pointer to element, but actually checked).

This fixes most of the trivial ones, by making the function declaration
match the function definition, and in the case of intel_pm.c, removing
the over-specified array size from the argument declaration.

At least one 'stringop-overread' warning remains in the i915 driver, but
that one doesn't have the same obvious trivial fix, and may or may not
actually be indicative of a bug.

[ It was a mistake to upgrade one of my machines to Fedora 34 while
  being busy with the merge window, but if this is the extent of the
  compiler upgrade problems, things are better than usual    - Linus ]

   patch descriptions, but this is important as it allows more
   flexibility when using NFS and SELinux context mounts.

 - Properly differentiate between the subjective and objective LSM
   credentials; including support for the SELinux and Smack. My clumsy
   attempt at a proper fix for AppArmor didn't quite pass muster so John
   is working on a proper AppArmor patch, in the meantime this set of
   patches shouldn't change the behavior of AppArmor in any way. This

Pull AFS updates from David Howells:
 "Use the new netfs lib.

  Begin the process of overhauling the use of the fscache API by AFS and
  the introduction of support for features such as Transparent Huge
  Pages (THPs).

   - Add some support for THPs, including using core VM helper functions
     to find details of pages.

   - Use the ITER_XARRAY I/O iterator to mediate access to the pagecache
     as this handles THPs and doesn't require allocation of large bvec
     arrays.

   - Delegate address_space read/pre-write I/O methods for AFS to the
     netfs helper library. A method is provided to the library that
     allows it to issue a read against the server.

     This includes a change in use for PG_fscache (it now indicates a
     DIO write in progress from the marked page), so a number of waits
     need to be deployed for it.

   - Split the core AFS writeback function to make it easier to modify
     in future patches to handle writing to the cache. [This might
     feasibly make more sense moved out into my fscache-iter branch].

  I've tested these with "xfstests -g quick" against an AFS volume
  (xfstests needs patching to make it work). With this, AFS without a
  cache passes all expected xfstests; with a cache, there's an extra
  failure, but that's also there before these patches. Fixing that
  probably requires a greater overhaul (as can be found on my

Pull network filesystem helper library updates from David Howells:
 "Here's a set of patches for 5.13 to begin the process of overhauling
  the local caching API for network filesystems. This set consists of
  two parts:

  (1) Add a helper library to handle the new VM readahead interface.

      This is intended to be used unconditionally by the filesystem
      (whether or not caching is enabled) and provides a common
      framework for doing caching, transparent huge pages and, in the
      future, possibly fscrypt and read bandwidth maximisation. It also
      allows the netfs and the cache to align, expand and slice up a
      read request from the VM in various ways; the netfs need only
      provide a function to read a stretch of data to the pagecache and
      the helper takes care of the rest.

  (2) Add an alternative fscache/cachfiles I/O API that uses the kiocb
      facility to do async DIO to transfer data to/from the netfs's
      pages, rather than using readpage with wait queue snooping on one
      side and vfs_write() on the other. It also uses less memory, since
      it doesn't do buffered I/O on the backing file.

      Note that this uses SEEK_HOLE/SEEK_DATA to locate the data
      available to be read from the cache. Whilst this is an improvement
      from the bmap interface, it still has a problem with regard to a
      modern extent-based filesystem inserting or removing bridging
      blocks of zeros. Fixing that requires a much greater overhaul.

  This is a step towards overhauling the fscache API. The change is
  opt-in on the part of the network filesystem. A netfs should not try
  to mix the old and the new API because of conflicting ways of handling
  pages and the PG_fscache page flag and because it would be mixing DIO
  with buffered I/O. Further, the helper library can't be used with the
  old API.

  This does not change any of the fscache cookie handling APIs or the
  way invalidation is done at this time.

  In the near term, I intend to deprecate and remove the old I/O API
  (fscache_allocate_page{,s}(), fscache_read_or_alloc_page{,s}(),
  fscache_write_page() and fscache_uncache_page()) and eventually
  replace most of fscache/cachefiles with something simpler and easier
  to follow.

  This patchset contains the following parts:

   - Some helper patches, including provision of an ITER_XARRAY iov
     iterator and a function to do readahead expansion.

   - Patches to add the netfs helper library.

   - A patch to add the fscache/cachefiles kiocb API.

   - A pair of patches to fix some review issues in the ITER_XARRAY and
     read helpers as spotted by Al and Willy.

  Jeff Layton has patches to add support in Ceph for this that he
  intends for this merge window. I have a set of patches to support AFS
  that I will post a separate pull request for.

  With this, AFS without a cache passes all expected xfstests; with a
  cache, there's an extra failure, but that's also there before these
  patches. Fixing that probably requires a greater overhaul. Ceph also
  passes the expected tests.

  I also have patches in a separate branch to tidy up the handling of
  PG_fscache/PG_private_2 and their contribution to page refcounting in
  the core kernel here, but I haven't included them in this set and will
  route them separately"

Pull CFI on arm64 support from Kees Cook:
 "This builds on last cycle's LTO work, and allows the arm64 kernels to
  be built with Clang's Control Flow Integrity feature. This feature has
  happily lived in Android kernels for almost 3 years[1], so I'm excited
  to have it ready for upstream.

  The wide diffstat is mainly due to the treewide fixing of mismatched
  list_sort prototypes. Other things in core kernel are to address
  various CFI corner cases. The largest code portion is the CFI runtime
  implementation itself (which will be shared by all architectures
  implementing support for CFI). The arm64 pieces are Acked by arm64
  maintainers rather than coming through the arm64 tree since carrying
  this tree over there was going to be awkward.

  CFI support for x86 is still under development, but is pretty close.
  There are a handful of corner cases on x86 that need some improvements
  to Clang and objtool, but otherwise works well.

Harald Arnesen reported [1] a deadlock at reboot time, and after
he captured a stack trace a picture developed of what's going on:

The distribution he's using is using iwd (not wpa_supplicant) to
manage wireless. iwd will usually use the "socket owner" option
when it creates new interfaces, so that they're automatically
destroyed when it quits (unexpectedly or otherwise). This is also
done by wpa_supplicant, but it doesn't do it for the normal one,
only for additional ones, which is different with iwd.

Anyway, during shutdown, iwd quits while the netdev is still UP,
i.e. IFF_UP is set. This causes the stack trace that Linus so
nicely transcribed from the pictures:

cfg80211_destroy_iface_wk() takes wiphy_lock
 -> cfg80211_destroy_ifaces()
  ->ieee80211_del_iface
    ->ieeee80211_if_remove
      ->cfg80211_unregister_wdev
        ->unregister_netdevice_queue
          ->dev_close_many
            ->__dev_close_many
              ->raw_notifier_call_chain
                ->cfg80211_netdev_notifier_call
and that last call tries to take wiphy_lock again.

In commit a05829a7 ("cfg80211: avoid holding the RTNL when
calling the driver") I had taken into account the possibility of
recursing from cfg80211 into cfg80211_netdev_notifier_call() via
the network stack, but only for NETDEV_UNREGISTER, not for what
happens here, NETDEV_GOING_DOWN and NETDEV_DOWN notifications.

Additionally, while this worked still back in commit 78f22b6a
("cfg80211: allow userspace to take ownership of interfaces"), it
missed another corner case: unregistering a netdev will cause
dev_close() to be called, and thus stop wireless operations (e.g.
disconnecting), but there are some types of virtual interfaces in
wifi that don't have a netdev - for that we need an additional
call to cfg80211_leave().

So, to fix this mess, change cfg80211_destroy_ifaces() to not
require the wiphy_lock(), but instead make it acquire it, but
only after it has actually closed all the netdevs on the list,
and then call cfg80211_leave() as well before removing them
from the driver, to fix the second issue. The locking change in
this requires modifying the nl80211 call to not get the wiphy
lock passed in, but acquire it by itself after flushing any
potentially pending destruction requests.

  firmware/dmi: Include product_sku info to modalias

Fix some miscellaneous things in the new netfs lib[1]:

 (1) The kerneldoc for netfs_readpage() shouldn't say netfs_page().

 (2) netfs_readpage() can get an integer overflow on 32-bit when it
     multiplies page_index(page) by PAGE_SIZE.  It should use
     page_file_offset() instead.

 (3) netfs_write_begin() should use page_offset() to avoid the same

Note that netfs_readpage() needs to use page_file_offset() rather than
page_offset() as it may see swap-over-NFS.
