Generating and retrieving socket cookies are a useful feature that is
exposed to BPF for various program types through bpf_get_socket_cookie()
helper.
The fact that the cookie counter is per netns is quite a limitation
for BPF in practice in particular for programs in host namespace that
use socket cookies as part of a map lookup key since they will be
causing socket cookie collisions e.g. when attached to BPF cgroup hooks
or cls_bpf on tc egress in host namespace handling container traffic
from veth or ipvlan devices with peer in different netns. Change the
counter to be global instead.
Socket cookie consumers must assume the value as opqaue in any case.
Not every socket must have a cookie generated and knowledge of the
counter value itself does not provide much value either way hence
conversion to global is fine.

It has been requested that usbfs should implement runtime power
management, instead of forcing the device to remain at full power as
long as the device file is open. This patch introduces that new
feature.
It does so by adding three new usbfs ioctls:
USBDEVFS_FORBID_SUSPEND: Prevents the device from going into
runtime suspend (and causes a resume if the device is already
suspended).
USBDEVFS_ALLOW_SUSPEND: Allows the device to go into runtime
suspend. Some time may elapse before the device actually is
suspended, depending on things like the autosuspend delay.
USBDEVFS_WAIT_FOR_RESUME: Blocks until the call is interrupted
by a signal or at least one runtime resume has occurred since
the most recent ALLOW_SUSPEND ioctl call (which may mean
immediately, even if the device is currently suspended). In
the latter case, the device is prevented from suspending again
just as if FORBID_SUSPEND was called before the ioctl returns.
For backward compatibility, when the device file is first opened
runtime suspends are forbidden. The userspace program can then allow
suspends whenever it wants, and either resume the device directly (by
forbidding suspends again) or wait for a resume from some other source
(such as a remote wakeup). URBs submitted to a suspended device will
fail or will complete with an appropriate error code.
This combination of ioctls is sufficient for user programs to have
nearly the same degree of control over a device's runtime power
behavior as kernel drivers do.
Still lacking is documentation for the new ioctls. I intend to add it
later, after the existing documentation for the usbfs userspace API is
straightened out into a reasonable form.

Add support for madvise and a shrinker similar to other drivers. This
allows userspace to mark BOs which can be freed when there is memory
pressure.
Unlike other implementations, we don't depend on struct_mutex. The
driver maintains a list of BOs which can be freed when the shrinker
is called. Access to the list is serialized with the shrinker_lock.

It is not desirable to relax the ABI to allow tagged user addresses into
the kernel indiscriminately. This patch introduces a prctl() interface
for enabling or disabling the tagged ABI with a global sysctl control
for preventing applications from enabling the relaxed ABI (meant for
testing user-space prctl() return error checking without reconfiguring
the kernel). The ABI properties are inherited by threads of the same
application and fork()'ed children but cleared on execve(). A Kconfig
option allows the overall disabling of the relaxed ABI.
The PR_SET_TAGGED_ADDR_CTRL will be expanded in the future to handle
MTE-specific settings like imprecise vs precise exceptions.

ASoC: Fixes for v5.3
A relatively large batch of mostly unremarkable fixes here, a couple of
small core fixes for fairly obscure issues, more comment/email updates
with no code impact than usual and a bunch of small driver fixes.
The support for new sample rates in the max98373 driver is a fix for the
fact that the driver declared support for those rates but would in fact
return an error if these rates were selected.

In order to support virtualization usage via PCIe SRIOV, this patch
adds two ioctls under FPGA Management Engine (FME) to release and
assign back the port device. In order to safely turn Port from PF
into VF and enable PCIe SRIOV, it requires user to invoke this
PORT_RELEASE ioctl to release port firstly to remove userspace
interfaces, and then configure the PF/VF access register in FME.
After disable SRIOV, it requires user to invoke this PORT_ASSIGN
ioctl to attach the port back to PF.
Ioctl interfaces:
* DFL_FPGA_FME_PORT_RELEASE
Release platform device of given port, it deletes port platform
device to remove related userspace interfaces on PF. After this
function, then it's safe to configure PF/VF access mode to VF,
and enable VFs via SRIOV.
* DFL_FPGA_FME_PORT_ASSIGN
Assign platform device of given port back to PF. After configure
PF/VF access mode to PF, this ioctl adds port platform device
back to re-enable related userspace interfaces on PF.

^~~~~~~~~~~~~~
This is because the commit 20c9c825b12f ("[SCTP] Fix SCTP socket options
to work with 32-bit apps on 64-bit kernels.") added "packed, aligned(4)"
GCC attributes to some structures but one of the members, i.e, "struct
sockaddr_storage" in those structures has the attribute,
"aligned(__alignof__ (struct sockaddr *)" which is 8-byte on 64-bit
systems, so the commit overwrites the designed alignments for
"sockaddr_storage".
To fix this, "struct sockaddr_storage" needs to be aligned to 4-byte as
it is only used in those packed sctp structure which is part of UAPI,
and "struct __kernel_sockaddr_storage" is used in some other
places of UAPI that need not to change alignments in order to not
breaking userspace.
Use an implicit alignment for "struct __kernel_sockaddr_storage" so it
can keep the same alignments as a member in both packed and un-packed
structures without breaking UAPI.

This adds the P_PIDFD type to waitid().
One of the last remaining bits for the pidfd api is to make it possible
to wait on pidfds. With P_PIDFD added to waitid() the parts of userspace
that want to use the pidfd api to exclusively manage processes can do so
now.
One of the things this will unblock in the future is the ability to make
it possible to retrieve the exit status via waitid(P_PIDFD) for
non-parent processes if handed a _suitable_ pidfd that has this feature
set. This is similar to what you can do on FreeBSD with kqueue(). It
might even end up being possible to wait on a process as a non-parent if
an appropriate property is enabled on the pidfd.
With P_PIDFD no scoping of the process identified by the pidfd is
possible, i.e. it explicitly blocks things such as wait4(-1), wait4(0),
waitid(P_ALL), waitid(P_PGID) etc. It only allows for semantics
equivalent to wait4(pid), waitid(P_PID). Users that need scoping should
rely on pid-based wait*() syscalls for now.

In user-space there's no way to distinguish why an mdb entry was deleted
and that is a problem for daemons which would like to keep the mdb in
sync with remote ends (e.g. mlag) but would also like to converge faster.
In almost all cases we'd like to age-out the remote entry for performance
and convergence reasons except when fast-leave is enabled. In that case we
want explicit immediate remote delete, thus add mdb flag which is set only
when the entry is being deleted due to fast-leave.

A common pattern when using xdp_redirect_map() is to create a device map
where the lookup key is simply ifindex. Because device maps are arrays,
this leaves holes in the map, and the map has to be sized to fit the
largest ifindex, regardless of how many devices actually are actually
needed in the map.
This patch adds a second type of device map where the key is looked up
using a hashmap, instead of being used as an array index. This allows maps
to be densely packed, so they can be smaller.

Add FS_VERITY_FL to the flags for FS_IOC_GETFLAGS, so that applications
can easily determine whether a file is a verity file at the same time as
they're checking other file flags. This flag will be gettable only;
FS_IOC_SETFLAGS won't allow setting it, since an ioctl must be used
instead to provide more parameters.
This flag matches the on-disk bit that was already allocated for ext4.

Add the UAPI header for fs-verity, including two ioctls:
- FS_IOC_ENABLE_VERITY
- FS_IOC_MEASURE_VERITY
These ioctls are documented in the "User API" section of
Documentation/filesystems/fsverity.rst.
Examples of using these ioctls can be found in fsverity-utils
(https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/fsverity-utils.git).
I've also written xfstests that test these ioctls

UAPI headers licensed under GPL are supposed to have exception
"WITH Linux-syscall-note" so that they can be included into non-GPL
user space application code.
The exception note is missing in some UAPI headers.
Some of them slipped in by the treewide conversion commit b24413180f56
("License cleanup: add SPDX GPL-2.0 license identifier to files with
no license"). Just run:
$ git show --oneline b24413180f56 -- arch/x86/include/uapi/asm/
I believe they are not intentional, and should be fixed too.
This patch was generated by the following script:
git grep -l --not -e Linux-syscall-note --and -e SPDX-License-Identifier \
-- :arch/*/include/uapi/asm/*.h :include/uapi/ :^*/Kbuild |
while read file
do
sed -i -e '/[[:space:]]OR[[:space:]]/s/\(GPL-[^[:space:]]*\)/(\1 WITH Linux-syscall-note)/g' \
-e '/[[:space:]]or[[:space:]]/s/\(GPL-[^[:space:]]*\)/(\1 WITH Linux-syscall-note)/g' \
-e '/[[:space:]]OR[[:space:]]/!{/[[:space:]]or[[:space:]]/!s/\(GPL-[^[:space:]]*\)/\1 WITH Linux-syscall-note/g}' $file
done
After this patch is applied, there are 5 UAPI headers that do not contain
"WITH Linux-syscall-note". They are kept untouched since this exception
applies only to GPL variants.

MPX is being removed from the kernel due to a lack of support in the
toolchain going forward (gcc).
The first step is to remove the userspace-visible ABIs so that applications
will stop using it. The most visible one are the enable/disable prctl()s.
Remove them first.
This is the most minimal and least invasive change needed to ensure that
apps stop using MPX with new kernels.

It allows the usage of the FlySky FS-i6 and other AFHDS compliant remote

To use it, a patch to inputattach which adds the FS-iA6B as a 115200 baud
serial device is required. I will upstream it after this patch is merged.
