"Including fixes from netfilter, bpf and wireless.
Still no major regressions, the release continues to be calm. An
uptick of fixes this time around due to trivial data race fixes and
patches flowing down from subtrees.
There has been a few driver fixes (particularly a few fixes for false
positives due to 66e4c8d950 which went into -next in May!) that make
me worry the wide testing is not exactly fully through.
So "calm" but not "let's just cut the final ASAP" vibes over here.

Some of the statistics values exported by KVM are always only 0 or 1.
It can be useful to export this fact to userspace so that it can track
them specially (for example by polling the value every now and then to
compute a % of time spent in a specific state).
Therefore, add "boolean value" as a new "unit". While it is not exactly
a unit, it walks and quacks like one. In particular, using the type
would be wrong because boolean values could be instantaneous or peak
values (e.g. "is the rmap allocated?") or even two-bucket histograms
(e.g. "number of posted vs. non-posted interrupt injections").

check_write_begin() will unlock and put the folio when return
non-zero. So we should avoid unlocking and putting it twice in
netfs layer.
Change the way ->check_write_begin() works in the following two ways:
(1) Pass it a pointer to the folio pointer, allowing it to unlock and put
the folio prior to doing the stuff it wants to do, provided it clears
the folio pointer.
(2) Change the return values such that 0 with folio pointer set means
continue, 0 with folio pointer cleared means re-get and all error
codes indicating an error (no special treatment for -EAGAIN).

This pull request contains the fix for an old and subtle bug in the
migration path. css_sets are used to track tasks and migrations are tasks
moving from a group of css_sets to another group of css_sets. The migration
path pins all source and destination css_sets in the prep stage.
Unfortunately, it was overloading the same list_head entry to track sources
and destinations, which got confused for migrations which are partially
identity leading to use-after-frees. Fixed by using dedicated list_heads for
tracking sources and destinations.

impact on x86, but may have a bit bigger impact on other architectures.

Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) refcount_inc_not_zero() is not semantically equivalent to
atomic_int_not_zero(), from Florian Westphal. My understanding was
that refcount_*() API provides a wrapper to easier debugging of
reference count leaks, however, there are semantic differences
between these two APIs, where refcount_inc_not_zero() needs a barrier.
Reason for this subtle difference to me is unknown.
2) packet logging is not correct for ARP and IP packets, from the
ARP family and netdev/egress respectively. Use skb_network_offset()
to reach the headers accordingly.
3) set element extension length have been growing over time, replace
a BUG_ON by EINVAL which might be triggerable from userspace.

Today, the resolution of size axes is not documented. As a result, it's
not clear what the canonical interpretation of this value should be. On
Android, there is a need to calculate the size of the touch ellipse in
physical units (millimeters).
After reviewing linux source, it turned out that most of the existing
usages are already interpreting this value as "units/mm". This
documentation will make it explicit. This will help device
implementations with correctly following the linux specs, and will
ensure that the devices will work on Android without needing further
customized parameters for scaling of major/minor values.

Merge tag 'fscache-fixes-20220708' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull fscache fixes from David Howells:
- Fix a check in fscache_wait_on_volume_collision() in which the
polarity is reversed. It should complain if a volume is still marked
acquisition-pending after 20s, but instead complains if the mark has
been cleared (ie. the condition has cleared).
Also switch an open-coded test of the ACQUIRE_PENDING volume flag to
use the helper function for consistency.
- Not a fix per se, but neaten the code by using a helper to check for
the DROPPED state.
- Fix cachefiles's support for erofs to only flush requests associated
with a released control file, not all requests.
- Fix a race between one process invalidating an object in the cache
and another process trying to look it up.

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.

Commit 13bbbfbea7 ("bpf: Add bpf_dynptr_read and bpf_dynptr_write")
added the bpf_dynptr_write() and bpf_dynptr_read() APIs.
However, it will be needed for some dynptr types to pass in flags as
well (e.g. when writing to a skb, the user may like to invalidate the
hash or recompute the checksum).
This patch adds a "u64 flags" arg to the bpf_dynptr_read() and
bpf_dynptr_write() APIs before their UAPI signature freezes where
we then cannot change them anymore with a 5.19.x released kernel.

We need to prevent that users configure a screen size which is smaller than the
currently selected font size. Otherwise rendering chars on the screen will
access memory outside the graphics memory region.
This patch adds a new function fbcon_modechange_possible() which
implements this check and which later may be extended with other checks
if necessary. The new function is called from the FBIOPUT_VSCREENINFO
ioctl handler in fbmem.c, which will return -EINVAL if userspace asked
for a too small screen size.

Almost all changes are device-specific small fixes, while many of

Offloading police with action TC_ACT_UNSPEC was erroneously disabled even
though it was supported by mlx5 matchall offload implementation, which
didn't verify the action type but instead assumed that any single police
action attached to matchall classifier is a 'continue' action. Lack of
action type check made it non-obvious what mlx5 matchall implementation
actually supports and caused implementers and reviewers of referenced
commits to disallow it as a part of improved validation code.

The IOMMU driver shares the pasid table for PCI alias devices. When the
RID2PASID entry of the shared pasid table has been filled by the first
device, the subsequent device will encounter the "DMAR: Setup RID2PASID
failed" failure as the pasid entry has already been marked as present.
As the result, the IOMMU probing process will be aborted.
On the contrary, when any alias device is hot-removed from the system,
for example, by writing to /sys/bus/pci/devices/.../remove, the shared
RID2PASID will be cleared without any notifications to other devices.
As the result, any DMAs from those rest devices are blocked.
Sharing pasid table among PCI alias devices could save two memory pages
for devices underneath the PCIe-to-PCI bridges. Anyway, considering that
those devices are rare on modern platforms that support VT-d in scalable
mode and the saved memory is negligible, it's reasonable to remove this
part of immature code to make the driver feasible and stable.

commit 72f2ecb7ec ("ACPI: bus: Set CPPC _OSC bits for all and
when CPPC_LIB is supported") added support for claiming to
support CPPC in _OSC on non-Intel platforms.
This unfortunately caused a regression on a vartiety of AMD
platforms in the field because a number of AMD platforms don't set
the `_OSC` bit 5 or 6 to indicate CPPC or CPPC v2 support.
As these AMD platforms already claim CPPC support via a dedicated
MSR from `X86_FEATURE_CPPC`, use this enable this feature rather
than requiring the `_OSC` on platforms with a dedicated MSR.
If there is additional breakage on the shared memory designs also
missing this _OSC, additional follow up changes may be needed.

Previously the kernel used to ignore whether the firmware masked CPPC
or CPPCv2 and would just pretend that it worked.
When support for the USB4 bit in _OSC was introduced from commit
9e1f561afb ("ACPI: Execute platform _OSC also with query bit clear")
the kernel began to look at the return when the query bit was clear.
This caused regressions that were misdiagnosed and attempted to be solved
as part of commit 2ca8e62852 ("Revert "ACPI: Pass the same capabilities
to the _OSC regardless of the query flag""). This caused a different
regression where non-Intel systems weren't able to negotiate _OSC
properly.
This was reverted in commit 2ca8e62852 ("Revert "ACPI: Pass the same
capabilities to the _OSC regardless of the query flag"") and attempted to
be fixed by commit c42fa24b44 ("ACPI: bus: Avoid using CPPC if not
supported by firmware") but the regression still returned.
These systems with the regression only load support for CPPC from an SSDT
dynamically when _OSC reports CPPC v2. Avoid the problem by not letting
CPPC satisfy the requirement in `acpi_cppc_processor_probe`.

If an NFS file is opened for writing and closed, fscache_invalidate() will
be asked to invalidate the file - however, if the cookie is in the
LOOKING_UP state (or the CREATING state), then request to invalidate
doesn't get recorded for fscache_cookie_state_machine() to do something
with.
Fix this by making __fscache_invalidate() set a flag if it sees the cookie
is in the LOOKING_UP state to indicate that we need to go to invalidation.
Note that this requires a count on the n_accesses counter for the state
machine, which that will release when it's done.
fscache_cookie_state_machine() then shifts to the INVALIDATING state if it
sees the flag.
Without this, an nfs file can get corrupted if it gets modified locally and
then read locally as the cache contents may not get updated.

Looking at the conditional lock acquire functions in the kernel due to
the new sparse support (see commit 4a557a5d1a "sparse: introduce
conditional lock acquire function attribute"), it became obvious that
the lockref code has a couple of them, but they don't match the usual
naming convention for the other ones, and their return value logic is
also reversed.
In the other very similar places, the naming pattern is '*_and_lock()'
(eg 'atomic_put_and_lock()' and 'refcount_dec_and_lock()'), and the
function returns true when the lock is taken.
The lockref code is superficially very similar to the refcount code,
only with the special "atomic wrt the embedded lock" semantics. But
instead of the '*_and_lock()' naming it uses '*_or_lock()'.
And instead of returning true in case it took the lock, it returns true
if it *didn't* take the lock.
Now, arguably the reflock code is quite logical: it really is a "either
decrement _or_ lock" kind of situation - and the return value is about
whether the operation succeeded without any special care needed.
So despite the similarities, the differences do make some sense, and
maybe it's not worth trying to unify the different conditional locking
primitives in this area.
But while looking at this all, it did become obvious that the
'lockref_get_or_lock()' function hasn't actually had any users for
almost a decade.
The only user it ever had was the shortlived 'd_rcu_to_refcount()'
function, and it got removed and replaced with 'lockref_get_not_dead()'
back in 2013 in commits 0d98439ea3 ("vfs: use lockred 'dead' flag to
mark unrecoverably dead dentries") and e5c832d555 ("vfs: fix dentry
RCU to refcounting possibly sleeping dput()")
In fact, that single use was removed less than a week after the whole
function was introduced in commit b3abd80250 ("lockref: add
'lockref_get_or_lock() helper") so this function has been around for a
decade, but only had a user for six days.
Let's just put this mis-designed and unused function out of its misery.
We can think about the naming and semantic oddities of the remaining
'lockref_put_or_lock()' later, but at least that function has users.
And while the naming is different and the return value doesn't match,
that function matches the whole '{atomic,refcount}_dec_and_test()'
pattern much better (ie the magic happens when the count goes down to
zero, not when it is incremented from zero).
