When working in "fd mode", fanotify_read() needs to open an fd
from a dentry to report event->fd to userspace.
Opening an fd from dentry can fail for several reasons.
For example, when tasks are gone and we try to open their
/proc files or we try to open a WRONLY file like in sysfs
or when trying to open a file that was deleted on the
remote network server.
Add a new flag FAN_REPORT_FD_ERROR for fanotify_init().
For a group with FAN_REPORT_FD_ERROR, we will send the
event with the error instead of the open fd, otherwise
userspace may not get the error at all.
For an overflow event, we report -EBADF to avoid confusing FAN_NOFD
with -EPERM. Similarly for pidfd open errors we report either -ESRCH
or the open error instead of FAN_NOPIDFD and FAN_EPIDFD.
In any case, userspace will not know which file failed to
open, so add a debug print for further investigation.

Add support for frame-based frame format, which can be used to support
multiple formats like H264 or H265, in addition to MJPEG and YUV frames.
The frame-based format is set to H264 by default, but it can be updated
to other formats by modifying the GUID through the guid configfs
attribute. Different structures are used for all three formats, as
H264 has a different structure compared to MJPEG and uncompressed
formats. These structures will be passed to the frame make function
based on the active format, using a common frame structure with
additional parameters needed only for frame-based formats. These
parameters are handled at runtime in the UVC driver.

The user thresholds mechanism is a way to have the userspace to tell
the thermal framework to send a notification when a temperature limit
is crossed. There is no id, no hysteresis, just the temperature and
the direction of the limit crossing. That means we can be notified
when a threshold is crossed the way up only, or the way down only or
both ways. That allows to create hysteresis values if it is needed.
A threshold can be added, deleted or flushed. The latter means all
thresholds belonging to a thermal zone will be deleted.
When a threshold is added:
- if the same threshold (temperature and direction) exists, an error
is returned
- if a threshold is specified with the same temperature but a
different direction, the specified direction is added
- if there is no threshold with the same temperature then it is
created
When a threshold is deleted:
- if the same threshold (temperature and direction) exists, it is
deleted
- if a threshold is specified with the same temperature but a
different direction, the specified direction is removed
- if there is no threshold with the same temperature, then an error
is returned
When the threshold are flushed:
- All thresholds related to a thermal zone are deleted
When a threshold is crossed:
- the userspace does not need to know which threshold(s) have been
crossed, it will be notified with the current temperature and the
previous temperature
- if multiple thresholds have been crossed between two updates only
one notification will be send to the userspace, it is pointless to
send a notification per thresholds crossed as the userspace can
handle that easily when it has the temperature delta information

The vmclock device addresses the problem of live migration with
precision clocks. The tolerances of a hardware counter (e.g. TSC) are
typically around ±50PPM. A guest will use NTP/PTP/PPS to discipline that
counter against an external source of 'real' time, and track the precise
frequency of the counter as it changes with environmental conditions.
When a guest is live migrated, anything it knows about the frequency of
the underlying counter becomes invalid. It may move from a host where
the counter running at -50PPM of its nominal frequency, to a host where
it runs at +50PPM. There will also be a step change in the value of the
counter, as the correctness of its absolute value at migration is
limited by the accuracy of the source and destination host's time
synchronization.
In its simplest form, the device merely advertises a 'disruption_marker'
which indicates that the guest should throw away any NTP synchronization
it thinks it has, and start again.
Because the shared memory region can be exposed all the way to userspace
through the /dev/vmclock0 node, applications can still use time from a
fast vDSO 'system call', and check the disruption marker to be sure that
their timestamp is indeed truthful.
The structure also allows for the precise time, as known by the host, to
be exposed directly to guests so that they don't have to wait for NTP to
resync from scratch. The PTP driver consumes this information if present.
Like the KVM PTP clock, this PTP driver can convert TSC-based cross
timestamps into KVM clock values. Unlike the KVM PTP clock, it does so
only when such is actually helpful.
The values and fields are based on the nascent virtio-rtc specification,
and the intent is that a version (hopefully precisely this version) of
this structure will be included as an optional part of that spec. In the
meantime, this driver supports the simple ACPI form of the device which
is being shipped in certain commercial hypervisors (and submitted for
inclusion in QEMU).

On PTL platforms with media version 30.00, the fuse registers for
reporting L3 bank availability to the GT just read out as ~0 and do not
provide proper values. Xe does not use the L3 bank mask for anything
internally; it only passes the mask through to userspace via the GT
topology query.
Since we don't have any way to get the real L3 bank mask, we don't want
to pass garbage to userspace. Passing a zeroed mask or a copy of the
primary GT's L3 bank mask would also be inaccurate and likely to cause
confusion for userspace. The best approach is to simply not include L3
in the list of masks returned by the topology query in cases where we
aren't able to provide a meaningful value. This won't change the
behavior for any existing platforms (where we can always obtain L3 masks
successfully for all GTs), it will only prevent us from mis-reporting
bad information on upcoming platform(s).
There's a good chance this will become a formal workaround in the
future, but for now we don't have a lineage number so "no_media_l3" is
used in place of a lineage as the OOB workaround descriptor.
v2:
- Re-calculate query size to properly match data returned. (Gustavo)
- Update kerneldoc to clarify that the L3bank mask may not be included
in the query results if the hardware doesn't make it available.

Giving the opportunity to userspace to associate a free-form
name with a drm_file struct is helpful for tracking and debugging.
This is similar to the existing DMA_BUF_SET_NAME ioctl.
Access to client_name is protected by a mutex, and the 'clients' debugfs
file has been updated to print it.
Userspace MR to use this ioctl:
https://gitlab.freedesktop.org/virgl/virglrenderer/-/merge_requests/1428
If the string passed by userspace contains chars that would mess up output
when it's going to be printed (in dmesg, fdinfo, etc), -EINVAL is returned.
A 0-length string is a valid use, and clears the existing name.

Jordan reported that when running Cilium with netkit in per-endpoint-routes
mode, network policy misclassifies traffic. In this direct routing mode
of Cilium which is used in case of GKE/EKS/AKS, the Pod's BPF program to
enforce policy sits on the netkit primary device's egress side.
The issue here is that in case of netkit's netkit_prep_forward(), it will
clear meta data such as skb->mark and skb->priority before executing the
BPF program. Thus, identity data stored in there from earlier BPF programs
(e.g. from tcx ingress on the physical device) gets cleared instead of
being made available for the primary's program to process. While for traffic
egressing the Pod via the peer device this might be desired, this is
different for the primary one where compared to tcx egress on the host
veth this information would be available.
To address this, add a new parameter for the device orchestration to
allow control of skb->mark and skb->priority scrubbing, to make the two
accessible from BPF (and eventually leave it up to the program to scrub).
By default, the current behavior is retained. For netkit peer this also
enables the use case where applications could cooperate/signal intent to
the BPF program.
Note that struct netkit has a 4 byte hole between policy and bundle which
is used here, in other words, struct netkit's first cacheline content used
in fast-path does not get moved around.

The "struct batadv_tvlv_tt_data" uses a dynamically sized set of
trailing elements. Specifically, it uses an array of structures of type
"batadv_tvlv_tt_vlan_data". So, use the preferred way in the kernel
declaring a flexible array [1].
At the same time, prepare for the coming implementation by GCC and Clang
of the __counted_by attribute. Flexible array members annotated with
__counted_by can have their accesses bounds-checked at run-time via
CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for
strcpy/memcpy-family functions). In this case, it is important to note
that the attribute used is specifically __counted_by_be since variable
"num_vlan" is of type __be16.
The following change to the "batadv_tt_tvlv_ogm_handler_v1" function:
- tt_vlan = (struct batadv_tvlv_tt_vlan_data *)(tt_data + 1);
- tt_change = (struct batadv_tvlv_tt_change *)(tt_vlan + num_vlan);
+ tt_change = (struct batadv_tvlv_tt_change *)((void *)tt_data
+ + flex_size);
is intended to prevent the compiler from generating an "out-of-bounds"
notification due to the __counted_by attribute. The compiler can do a
pointer calculation using the vlan_data flexible array memory, or in
other words, this may be calculated as an array offset, since it is the
same as:
&tt_data->vlan_data[num_vlan]
Therefore, we go past the end of the array. In other "multiple trailing
flexible array" situations, this has been solved by addressing from the
base pointer, since the compiler either knows the full allocation size
or it knows nothing about it (this case, since it came from a "void *"
function argument).
The order in which the structure batadv_tvlv_tt_data and the structure
batadv_tvlv_tt_vlan_data are defined must be swap to avoid an incomplete
type error.
Also, avoid the open-coded arithmetic in memory allocator functions [2]
using the "struct_size" macro and use the "flex_array_size" helper to
clarify some calculations, when possible.
Moreover, the new structure member also allow us to avoid the open-coded
arithmetic on pointers in some situations. Take advantage of this.
This code was detected with the help of Coccinelle, and audited and
modified manually.

The virtio crypto driver exposes akcipher sign/verify operations in a
user space ABI. This blocks removal of sign/verify from akcipher_alg.
Herbert opines:
"I would say that this is something that we can break. Breaking it
is no different to running virtio on a host that does not support
these algorithms. After all, a software implementation must always
be present.
I deliberately left akcipher out of crypto_user because the API
is still in flux. We should not let virtio constrain ourselves."
https://lore.kernel.org/all/ZtqoNAgcnXnrYhZZ@gondor.apana.org.au/
"I would remove virtio akcipher support in its entirety. This API
was never meant to be exposed outside of the kernel."
https://lore.kernel.org/all/Ztqql_gqgZiMW8zz@gondor.apana.org.au/
Drop sign/verify support from virtio crypto. There's no strong reason
to also remove encrypt/decrypt support, so keep it.
A key selling point of virtio crypto is to allow guest access to crypto
accelerators on the host. So far the only akcipher algorithm supported
by virtio crypto is RSA. Dropping sign/verify merely means that the
PKCS#1 padding is now always generated or verified inside the guest,
but the actual signature generation/verification (which is an RSA
decrypt/encrypt operation) may still use an accelerator on the host.
Generating or verifying the PKCS#1 padding is cheap, so a hardware
accelerator won't be of much help there. Which begs the question
whether virtio crypto support for sign/verify makes sense at all.
It would make sense for the sign operation if the host has a security
chip to store asymmetric private keys. But the kernel doesn't even
have an asymmetric_key_subtype yet for hardware-based private keys.
There's at least one rudimentary driver for such chips (atmel-ecc.c for
ATECC508A), but it doesn't implement the sign operation. The kernel
would first have to grow support for a hardware asymmetric_key_subtype
and at least one driver implementing the sign operation before exposure
to guests via virtio makes sense.

Commit 6cb8815f41a9 ("crypto: sig - Add interface for sign/verify")
began a transition of asymmetric sign/verify operations from
crypto_akcipher to a new crypto_sig frontend.
Internally, the crypto_sig frontend still uses akcipher_alg as backend,
however:
"The link between sig and akcipher is meant to be temporary. The
plan is to create a new low-level API for sig and then migrate
the signature code over to that from akcipher."
https://lore.kernel.org/r/ZrG6w9wsb-iiLZIF@gondor.apana.org.au/
"having a separate alg for sig is definitely where we want to
be since there is very little that the two types actually share."
https://lore.kernel.org/r/ZrHlpz4qnre0zWJO@gondor.apana.org.au/
Take the next step of that migration and augment the crypto_sig frontend
with a sig_alg backend to which all algorithms can be moved.
During the migration, there will briefly be signature algorithms that
are still based on crypto_akcipher, whilst others are already based on
crypto_sig. Allow for that by building a fork into crypto_sig_*() API
calls (i.e. crypto_sig_maxsize() and friends) such that one of the two
backends is selected based on the transform's cra_type.

SOF_TIMESTAMPING_OPT_ID socket option flag gives a way to correlate TX
timestamps and packets sent via socket. Unfortunately, there is no way
to reliably predict socket timestamp ID value in case of error returned
by sendmsg. For UDP sockets it's impossible because of lockless
nature of UDP transmit, several threads may send packets in parallel. In
case of RAW sockets MSG_MORE option makes things complicated. More
details are in the conversation [1].
This patch adds new control message type to give user-space
software an opportunity to control the mapping between packets and
values by providing ID with each sendmsg for UDP sockets.
The documentation is also added in this patch.

Three architectures (x86, aarch64, riscv) have announced support for
shadow stacks with fairly similar functionality. While x86 is using
arch_prctl() to control the functionality neither arm64 nor riscv uses
that interface so this patch adds arch-agnostic prctl() support to
get and set status of shadow stacks and lock the current configuation to
prevent further changes, with support for turning on and off individual
subfeatures so applications can limit their exposure to features that
they do not need. The features are:
- PR_SHADOW_STACK_ENABLE: Tracking and enforcement of shadow stacks,
including allocation of a shadow stack if one is not already
allocated.
- PR_SHADOW_STACK_WRITE: Writes to specific addresses in the shadow
stack.
- PR_SHADOW_STACK_PUSH: Push additional values onto the shadow stack.
These features are expected to be inherited by new threads and cleared
on exec(), unknown features should be rejected for enable but accepted
for locking (in order to allow for future proofing).
This is based on a patch originally written by Deepak Gupta but modified
fairly heavily, support for indirect landing pads is removed, additional
modes added and the locking interface reworked. The set status prctl()
is also reworked to just set flags, if setting/reading the shadow stack
pointer is required this could be a separate prctl.

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) Fix incorrect documentation in uapi/linux/netfilter/nf_tables.h
regarding flowtable hooks, from Phil Sutter.
2) Fix nft_audit.sh selftests with newer nft binaries, due to different
(valid) audit output, also from Phil.
3) Disable BH when duplicating packets via nf_dup infrastructure,
otherwise race on nf_skb_duplicated for locally generated traffic.
From Eric.
4) Missing return in callback of selftest C program, from zhang jiao.
