The unnamed struct sucks and is in the way of further cleanups. Stick the
PCI related MSI data into a real data structure and cleanup all users.
No functional change.

There is no point to have this function public as it is set by the PCI core
anyway when a PCI/MSI irqdomain is created.

Remove the kobject.h include from msi.h as it's not required and add a
sysfs.h include to the core code instead.

Pull scheduler fixes from Borislav Petkov:
- Properly init uclamp_flags of a runqueue, on first enqueuing
- Fix preempt= callback return values
- Correct utime/stime resource usage reporting on nohz_full to return
the proper times instead of shorter ones

sched/uclamp: Fix rq->uclamp_max not set on first enqueue

getrusage(RUSAGE_THREAD) with nohz_full may return shorter utime/stime
than the actual time.
task_cputime_adjusted() snapshots utime and stime and then adjust their
sum to match the scheduler maintained cputime.sum_exec_runtime.
Unfortunately in nohz_full, sum_exec_runtime is only updated once per
second in the worst case, causing a discrepancy against utime and stime
that can be updated anytime by the reader using vtime.
To fix this situation, perform an update of cputime.sum_exec_runtime
when the cputime snapshot reports the task as actually running while
the tick is disabled. The related overhead is then contained within the
relevant situations.

Pull drm fixes from Dave Airlie:
"Bit of an uptick in patch count this week, though it's all relatively
small overall.
I suspect msm has been queuing up a few fixes to skew it here.
Otherwise amdgpu has a scattered bunch of small fixes, and then some
vc4, i915.
virtio-gpu changes an rc1 introduced uAPI mistake, and makes it
operate more like other drivers. This should be fine as no userspace
relies on the behaviour yet.
Summary:
dma-buf:
- memory leak fix
msm:
- kasan found memory overwrite
- mmap flags
- fencing error bug
- ioctl NULL ptr
- uninit var
- devfreqless devices fix
- dsi lanes fix
- dp: avoid unpowered aux xfers
amdgpu:
- IP discovery based enumeration fixes
- vkms fixes
- DSC fixes for DP MST
- Audio fix for hotplug with tiled displays
- Misc display fixes
- DP tunneling fix
- DP fix
- Aldebaran fix
amdkfd:
- Locking fix
- Static checker fix
- Fix double free
i915:
- backlight regression
- Intel HDR backlight detection fix
- revert TGL workaround that caused hangs
virtio-gpu:
- switch back to drm_poll
vc4:
- memory leak
- error check fix
- HVS modesetting fixes"

The current virtgpu implementation of poll(..) drops events
when VIRTGPU_CONTEXT_PARAM_POLL_RINGS_MASK is enabled (otherwise
it's like a normal DRM driver).
This is because paravirtualized userspaces receives responses in a
buffer of type BLOB_MEM_GUEST, not by read(..).
To be in line with other DRM drivers and avoid specialized behavior,
it is possible to define a dummy event for virtgpu. Paravirtualized
userspace will now have to call read(..) on the DRM fd to receive the
dummy event.

After the change, this is no longer the case, as free_fib_info_rcu()

On ARM v6 and later, we define CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS
because the ordinary load/store instructions (ldr, ldrh, ldrb) can
tolerate any misalignment of the memory address. However, load/store
double and load/store multiple instructions (ldrd, ldm) may still only
be used on memory addresses that are 32-bit aligned, and so we have to
use the CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS macro with care, or we
may end up with a severe performance hit due to alignment traps that
require fixups by the kernel. Testing shows that this currently happens
with clang-13 but not gcc-11. In theory, any compiler version can
produce this bug or other problems, as we are dealing with undefined
behavior in C99 even on architectures that support this in hardware,
see also https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100363.
Fortunately, the get_unaligned() accessors do the right thing: when
building for ARMv6 or later, the compiler will emit unaligned accesses
using the ordinary load/store instructions (but avoid the ones that
require 32-bit alignment). When building for older ARM, those accessors
will emit the appropriate sequence of ldrb/mov/orr instructions. And on
architectures that can truly tolerate any kind of misalignment, the
get_unaligned() accessors resolve to the leXX_to_cpup accessors that
operate on aligned addresses.
Since the compiler will in fact emit ldrd or ldm instructions when
building this code for ARM v6 or later, the solution is to use the
unaligned accessors unconditionally on architectures where this is
known to be fast. The _aligned version of the hash function is
however still needed to get the best performance on architectures
that cannot do any unaligned access in hardware.
This new version avoids the undefined behavior and should produce
the fastest hash on all architectures we support.

Each peer's endpoint contains a dst_cache entry that takes a reference
to another netdev. When the containing namespace exits, we take down the
socket and prevent future sockets from being created (by setting
creating_net to NULL), which removes that potential reference on the
netns. However, it doesn't release references to the netns that a netdev
cached in dst_cache might be taking, so the netns still might fail to
exit. Since the socket is gimped anyway, we can simply clear all the
dst_caches (by way of clearing the endpoint src), which will release all
references.
However, the current dst_cache_reset function only releases those
references lazily. But it turns out that all of our usages of
wg_socket_clear_peer_endpoint_src are called from contexts that are not
exactly high-speed or bottle-necked. For example, when there's
connection difficulty, or when userspace is reconfiguring the interface.
And in particular for this patch, when the netns is exiting. So for
those cases, it makes more sense to call dst_release immediately. For
that, we add a small helper function to dst_cache.
This patch also adds a test to netns.sh from Hangbin Liu to ensure this
doesn't regress.

The kernel leaks memory when a `fib` rule is present in IPv6 nftables
firewall rules and a suppress_prefix rule is present in the IPv6 routing
rules (used by certain tools such as wg-quick). In such scenarios, every
incoming packet will leak an allocation in `ip6_dst_cache` slab cache.
After some hours of `bpftrace`-ing and source code reading, I tracked
down the issue to ca7a03c41753 ("ipv6: do not free rt if
FIB_LOOKUP_NOREF is set on suppress rule").
The problem with that change is that the generic `args->flags` always have
`FIB_LOOKUP_NOREF` set[1][2] but the IPv6-specific flag
`RT6_LOOKUP_F_DST_NOREF` might not be, leading to `fib6_rule_suppress` not
decreasing the refcount when needed.
How to reproduce:
- Add the following nftables rule to a prerouting chain:
meta nfproto ipv6 fib saddr . mark . iif oif missing drop
This can be done with:
sudo nft create table inet test
sudo nft create chain inet test test_chain '{ type filter hook prerouting priority filter + 10; policy accept; }'
sudo nft add rule inet test test_chain meta nfproto ipv6 fib saddr . mark . iif oif missing drop
- Run:
sudo ip -6 rule add table main suppress_prefixlength 0
- Watch `sudo slabtop -o | grep ip6_dst_cache` to see memory usage increase
with every incoming ipv6 packet.
This patch exposes the protocol-specific flags to the protocol
specific `suppress` function, and check the protocol-specific `flags`
argument for RT6_LOOKUP_F_DST_NOREF instead of the generic
FIB_LOOKUP_NOREF when decreasing the refcount, like this.

Steffen reported a TCP stream corruption for HTTP requests
served by the apache web-server using a cifs mount-point
and memory mapping the relevant file.
The root cause is quite similar to the one addressed by
commit 20eb4f29b602 ("net: fix sk_page_frag() recursion from
memory reclaim"). Here the nested access to the task page frag
is caused by a page fault on the (mmapped) user-space memory
buffer coming from the cifs file.
The page fault handler performs an smb transaction on a different
socket, inside the same process context. Since sk->sk_allaction
for such socket does not prevent the usage for the task_frag,
the nested allocation modify "under the hood" the page frag
in use by the outer sendmsg call, corrupting the stream.
The overall relevant stack trace looks like the following:
httpd 78268 [001] 3461630.850950: probe:tcp_sendmsg_locked:

The cifs filesystem rightfully sets sk_allocations to GFP_NOFS,
we can avoid the nesting using the sk page frag for allocation
lacking the __GFP_FS flag. Do not define an additional mm-helper
for that, as this is strictly tied to the sk page frag usage.
v1 -> v2:
- use a stricted sk_page_frag() check instead of reordering the
code (Eric)

The 'kprobe::data_size' is unsigned, thus it can not be negative. But if
user sets it enough big number (e.g. (size_t)-8), the result of 'data_size
+ sizeof(struct kretprobe_instance)' becomes smaller than sizeof(struct
kretprobe_instance) or zero. In result, the kretprobe_instance are
allocated without enough memory, and kretprobe accesses outside of
allocated memory.
To avoid this issue, introduce a max limitation of the
kretprobe::data_size. 4KB per instance should be OK.

Tegra kcontrols not correctly reporting changes to userspace, a fix for
some issues with matching on older x86 platforms introduced during the

Commit dac7cbd55dca ("ASoC: Intel: soc-acpi-byt: shrink tables using
compatible IDs") and commit 959ae8215a9e ("ASoC: Intel: soc-acpi-cht:
shrink tables using compatible IDs") simplified the match tables in
soc-acpi-intel-byt-match.c and soc-acpi-intel-cht-match.c by merging
identical entries using the new .comp_ids snd_soc_acpi_mach field to
point a single entry to multiple ACPI HIDs and clearing the previously
unique per entry .id field.
But various machine drivers from sound/soc/intel/boards rely on mach->id
in one or more ways, e.g. some drivers contain the following snippets:
adev = acpi_dev_get_first_match_dev(mach->id, NULL, -1);
pkg_found = snd_soc_acpi_find_package_from_hid(mach->id, ...
if (!strncmp(snd_soc_cards[i].codec_id, mach->id, 8)) { ...
All of which are broken by the match table shrinking.
Make the snd_soc_acpi_mach.id field non const (the storage for the tables
already is non const) and on a comps_ids match copy the matching HID to
the id field to fix this.

This reverts commit 939779f5152d161b34f612af29e7dc1ac4472fcf.
Attempts to validate length in the core did not work out: there turn out
to exist multiple broken devices, and in particular legacy devices are
known to be broken in this respect.
We have ideas for handling this better in the next version but for now
let's revert to a known good state to make sure drivers work for people.

As opposed to event messages (Sync, PdelayReq etc) which require
timestamping, general messages (Announce, FollowUp etc) do not.
In PTP they are part of different streams of data.
IEEE 1588-2008 Annex D.2 "UDP port numbers" states that the UDP
destination port assigned by IANA is 319 for event messages, and 320 for
general messages. Yet the kernel seems to be missing the definition for
general messages. This patch adds it.

VCAP (Versatile Content Aware Processor) is the TCAM-based engine behind
tc flower offload on ocelot, among other things. The ingress port mask
on which VCAP rules match is present as a bit field in the actual key of
the rule. This means that it is possible for a rule to be shared among
multiple source ports. When the rule is added one by one on each desired
port, that the ingress port mask of the key must be edited and rewritten
to hardware.
But the API in ocelot_vcap.c does not allow for this. For one thing,
ocelot_vcap_filter_add() and ocelot_vcap_filter_del() are not symmetric,
because ocelot_vcap_filter_add() works with a preallocated and
prepopulated filter and programs it to hardware, and
ocelot_vcap_filter_del() does both the job of removing the specified
filter from hardware, as well as kfreeing it. That is to say, the only
option of editing a filter in place, which is to delete it, modify the
structure and add it back, does not work because it results in
use-after-free.
This patch introduces ocelot_vcap_filter_replace, which trivially
reprograms a VCAP entry to hardware, at the exact same index at which it
existed before, without modifying any list or allocating any memory.

This patch fixes an issue that an u32 netlink value is handled as a
signed enum value which doesn't fit into the range of u32 netlink type.
If it's handled as -1 value some BIT() evaluation ends in a
shift-out-of-bounds issue. To solve the issue we set the to u32 max which
is s32 "-1" value to keep backwards compatibility and let the followed enum
values start counting at 0. This brings the compiler to never handle the

We need a way to release a fib6_nh's per-cpu dsts when replacing
nexthops otherwise we can end up with stale per-cpu dsts which hold net
device references, so add a new IPv6 stub called fib6_nh_release_dsts.
It must be used after an RCU grace period, so no new dsts can be created
through a group's nexthop entry.
Similar to fib6_nh_release it shouldn't be used if fib6_nh_init has failed
so it doesn't need a dummy stub when IPv6 is not enabled.

When booting the xenbus driver will wait for PV devices to have
connected to their backends before continuing. The timeout is different
between essential and non-essential devices.
Non-essential devices are identified by their nodenames directly in the
xenbus driver, which requires to update this list in case a new device
type being non-essential is added (this was missed for several types
in the past).
In order to avoid this problem, add a "not_essential" flag to struct
xenbus_driver which can be set to "true" by the respective frontend.
Set this flag for the frontends currently regarded to be not essential
(vkbs and vfb) and use it for testing in the xenbus driver.

Pull folio fixes from Matthew Wilcox:
"In the course of preparing the folio changes for iomap for next merge
window, we discovered some problems that would be nice to address now:
- Renaming multi-page folios to large folios.
mapping_multi_page_folio_support() is just a little too long, so we
settled on mapping_large_folio_support(). That meant renaming, eg
folio_test_multi() to folio_test_large().
Rename AS_THP_SUPPORT to match
- I hadn't included folio wrappers for zero_user_segments(), etc.
Also, multi-page^W^W large folio support is now independent of
CONFIG_TRANSPARENT_HUGEPAGE, so machines with HIGHMEM always need
to fall back to the out-of-line zero_user_segments().
Remove FS_THP_SUPPORT to match
- The build bots finally got round to telling me that I missed a
couple of architectures when adding flush_dcache_folio(). Christoph
suggested that we just add linux/cacheflush.h and not rely on
asm-generic/cacheflush.h"

These functions are wrappers around zero_user_segments(), which means
that zero_user_segments() can now be called for compound pages even when
CONFIG_TRANSPARENT_HUGEPAGE is disabled.
Use 'xend' as the name of the parameter to indicate that this is an
excluded end, not the more usual included end. Excluding the end makes
more sense to the callers, but can cause confusion to readers who are
more used to seeing included ends.

Many architectures do not include asm-generic/cacheflush.h, so turn
the includes on their head and add linux/cacheflush.h which includes
asm/cacheflush.h.
Move the flush_dcache_folio() declaration from asm-generic/cacheflush.h
to linux/cacheflush.h and change linux/highmem.h to include
linux/cacheflush.h instead of asm/cacheflush.h so that all necessary
places will see flush_dcache_folio().
More functions should have their default implementations moved in the
future, but those are for follow-on patches. This fixes csky, sparc and
sparc64 which were missed in the commit which added flush_dcache_folio().

A late addititon to the intel-ish-hid framework caused a build failure
with clang, and introduced an ABI to the module loader that stops working
if any driver ever needs to bind to more than one UUID:
drivers/hid/intel-ish-hid/ishtp-fw-loader.c:1067:4: error: initializer element is not a compile-time constant
Change the ishtp_device_id to have correct documentation and a driver_data
field like all the other ones, and change the drivers to use the ID table
as the primary identification in a way that works with all compilers
and avoids duplciating the identifiers.
