Pull scheduler updates from Ingo Molnar:
- The biggest change is introduction of a new iteration of the
SCHED_FAIR interactivity code: the EEVDF ("Earliest Eligible Virtual
Deadline First") scheduler
EEVDF too is a virtual-time scheduler, with two parameters (weight
and relative deadline), compared to CFS that had weight only. It
completely reworks the base scheduler: placement, preemption, picking
-- everything
LWN.net, as usual, has a terrific writeup about EEVDF:
https://lwn.net/Articles/925371/
Preemption (both tick and wakeup) is driven by testing against a
fresh pick. Because the tree is now effectively an interval tree, and
the selection is no longer the 'leftmost' task, over-scheduling is
less of a problem. A lot of the CFS heuristics are removed or
replaced by more natural latency-space parameters & constructs
In terms of expected performance regressions: we will and can fix
everything where a 'good' workload misbehaves with the new scheduler,
but EEVDF inevitably changes workload scheduling in a binary fashion,
hopefully for the better in the overwhelming majority of cases, but
in some cases it won't, especially in adversarial loads that got
lucky with the previous code, such as some variants of hackbench. We
are trying hard to err on the side of fixing all performance
regressions, but we expect some inevitable post-release iterations of
that process
- Improve load-balancing on hybrid x86 systems: enable cluster
scheduling (again)
- Improve & fix bandwidth-scheduling on nohz systems
- Improve bandwidth-throttling
- Use lock guards to simplify and de-goto-ify control flow

Pull CPU hotplug updates from Thomas Gleixner:
"Updates for the CPU hotplug core:
- Support partial SMT enablement.
So far the sysfs SMT control only allows to toggle between SMT on
and off. That's sufficient for x86 which usually has at max two
threads except for the Xeon PHI platform which has four threads per
core
Though PowerPC has up to 16 threads per core and so far it's only
possible to control the number of enabled threads per core via a
command line option. There is some way to control this at runtime,
but that lacks enforcement and the usability is awkward
This update expands the sysfs interface and the core infrastructure
to accept numerical values so PowerPC can build SMT runtime control
for partial SMT enablement on top
The core support has also been provided to the PowerPC maintainers
who added the PowerPC related changes on top

Pull btrfs updates from David Sterba:
"No new features, the bulk of the changes are fixes, refactoring and
cleanups. The notable fix is the scrub performance restoration after
rewrite in 6.4, though still only partial.
Fixes:
- scrub performance drop due to rewrite in 6.4 partially restored:
- do IO grouping by blg_plug/blk_unplug again
- avoid unnecessary tree searches when processing stripes, in
extent and checksum trees
- the drop is noticeable on fast PCIe devices, -66% and restored
to -33% of the original
- backports to 6.4 planned
- handle more corner cases of transaction commit during orphan
cleanup or delayed ref processing
- use correct fsid/metadata_uuid when validating super block
- copy directory permissions and time when creating a stub subvolume
Core:
- debugging feature integrity checker deprecated, to be removed in
6.7
- in zoned mode, zones are activated just before the write, making
error handling easier, now the overcommit mechanism can be enabled
again which improves performance by avoiding more frequent flushing
- v0 extent handling completely removed, deprecated long time ago
- error handling improvements
- tests:
- extent buffer bitmap tests
- pinned extent splitting tests
- cleanups and refactoring:
- compression writeback
- extent buffer bitmap
- space flushing, ENOSPC handling"

Pull iomap updates from Darrick Wong:
"We've got some big changes for this release -- I'm very happy to be
landing willy's work to enable large folios for the page cache for
general read and write IOs when the fs can make contiguous space
allocations, and Ritesh's work to track sub-folio dirty state to
eliminate the write amplification problems inherent in using large
folios.
As a bonus, io_uring can now process write completions in the caller's
context instead of bouncing through a workqueue, which should reduce
io latency dramatically. IOWs, XFS should see a nice performance bump
for both IO paths.
Summary:
- Make large writes to the page cache fill sparse parts of the cache
with large folios, then use large memcpy calls for the large folio.

Pull fchmodat2 system call from Christian Brauner:
"This adds the fchmodat2() system call. It is a revised version of the
fchmodat() system call, adding a missing flag argument. Support for
both AT_SYMLINK_NOFOLLOW and AT_EMPTY_PATH are included.
Adding this system call revision has been a longstanding request but
so far has always fallen through the cracks. While the kernel
implementation of fchmodat() does not have a flag argument the libc
provided POSIX-compliant fchmodat(3) version does. Both glibc and musl
have to implement a workaround in order to support AT_SYMLINK_NOFOLLOW
(see [1] and [2]).
The workaround is brittle because it relies not just on O_PATH and
O_NOFOLLOW semantics and procfs magic links but also on our rather
inconsistent symlink semantics.
This gives userspace a proper fchmodat2() system call that libcs can
use to properly implement fchmodat(3) and allows them to get rid of
their hacks. In this case it will immediately benefit them as the
current workaround is already defunct because of aformentioned
inconsistencies.
In addition to AT_SYMLINK_NOFOLLOW, give userspace the ability to use
AT_EMPTY_PATH with fchmodat2(). This is already possible with
fchownat() so there's no reason to not also support it for
fchmodat2().
The implementation is simple and comes with selftests. Implementation
of the system call and wiring up the system call are done as separate
patches even though they could arguably be one patch. But in case
there are merge conflicts from other system call additions it can be
beneficial to have separate patches"

Pull superblock updates from Christian Brauner:
"This contains the super rework that was ready for this cycle. The
first part changes the order of how we open block devices and allocate
superblocks, contains various cleanups, simplifications, and a new
mechanism to wait on superblock state changes.
This unblocks work to ultimately limit the number of writers to a
block device. Jan has already scheduled follow-up work that will be
ready for v6.7 and allows us to restrict the number of writers to a
given block device. That series builds on this work right here.
The second part contains filesystem freezing updates.
Overview:
The generic superblock changes are rougly organized as follows
(ignoring additional minor cleanups):
(1) Removal of the bd_super member from struct block_device.
This was a very odd back pointer to struct super_block with
unclear rules. For all relevant places we have other means to get
the same information so just get rid of this.
(2) Simplify rules for superblock cleanup.
Roughly, everything that is allocated during fs_context
initialization and that's stored in fs_context->s_fs_info needs
to be cleaned up by the fs_context->free() implementation before
the superblock allocation function has been called successfully.
After sget_fc() returned fs_context->s_fs_info has been
transferred to sb->s_fs_info at which point sb->kill_sb() if
fully responsible for cleanup. Adhering to these rules means that
cleanup of sb->s_fs_info in fill_super() is to be avoided as it's
brittle and inconsistent.
Cleanup shouldn't be duplicated between sb->put_super() as
sb->put_super() is only called if sb->s_root has been set aka
when the filesystem has been successfully born (SB_BORN). That
complexity should be avoided.
This also means that block devices are to be closed in
sb->kill_sb() instead of sb->put_super(). More details in the
lower section.
(3) Make it possible to lookup or create a superblock before opening
block devices
There's a subtle dependency on (2) as some filesystems did rely
on fill_super() to be called in order to correctly clean up
sb->s_fs_info. All these filesystems have been fixed.
(4) Switch most filesystem to follow the same logic as the generic
mount code now does as outlined in (3).
(5) Use the superblock as the holder of the block device. We can now
easily go back from block device to owning superblock.
(6) Export and extend the generic fs_holder_ops and use them as
holder ops everywhere and remove the filesystem specific holder
ops.
(7) Call from the block layer up into the filesystem layer when the
block device is removed, allowing to shut down the filesystem
without risk of deadlocks.
(8) Get rid of get_super().
We can now easily go back from the block device to owning
superblock and can call up from the block layer into the
filesystem layer when the device is removed. So no need to wade
through all registered superblock to find the owning superblock
anymore"

Pull libfs and tmpfs updates from Christian Brauner:
"This cycle saw a lot of work for tmpfs that required changes to the
vfs layer. Andrew, Hugh, and I decided to take tmpfs through vfs this
cycle. Things will go back to mm next cycle.
Features
========
- By far the biggest work is the quota support for tmpfs. New tmpfs
quota infrastructure is added to support it and a new QFMT_SHMEM
uapi option is exposed.
This offers user and group quotas to tmpfs (project quotas will be
added later). Similar to other filesystems tmpfs quota are not
supported within user namespaces yet.
- Add support for user xattrs. While tmpfs already supports security
xattrs (security.*) and POSIX ACLs for a long time it lacked
support for user xattrs (user.*). With this pull request tmpfs will
be able to support a limited number of user xattrs.
This is accompanied by a fix (see below) to limit persistent simple
xattr allocations.
- Add support for stable directory offsets. Currently tmpfs relies on
the libfs provided cursor-based mechanism for readdir. This causes
issues when a tmpfs filesystem is exported via NFS.
NFS clients do not open directories. Instead, each server-side
readdir operation opens the directory, reads it, and then closes
it. Since the cursor state for that directory is associated with
the opened file it is discarded after each readdir operation. Such
directory offsets are not just cached by NFS clients but also
various userspace libraries based on these clients.
As it stands there is no way to invalidate the caches when
directory offsets have changed and the whole application depends on
unchanging directory offsets.
At LSFMM we discussed how to solve this problem and decided to
support stable directory offsets. libfs now allows filesystems like
tmpfs to use an xarrary to map a directory offset to a dentry. This
mechanism is currently only used by tmpfs but can be supported by
others as well.
Fixes
=====
- Change persistent simple xattrs allocations in libfs from
GFP_KERNEL to GPF_KERNEL_ACCOUNT so they're subject to memory
cgroup limits. Since this is a change to libfs it affects both
tmpfs and kernfs.
- Correctly verify {g,u}id mount options.
A new filesystem context is created via fsopen() which records the
namespace that becomes the owning namespace of the superblock when
fsconfig(FSCONFIG_CMD_CREATE) is called for filesystems that are
mountable in namespaces. However, fsconfig() calls can occur in a
namespace different from the namespace where fsopen() has been
called.
Currently, when fsconfig() is called to set {g,u}id mount options
the requested {g,u}id is mapped into a k{g,u}id according to the
namespace where fsconfig() was called from. The resulting k{g,u}id
is not guaranteed to be resolvable in the namespace of the
filesystem (the one that fsopen() was called in).
This means it's possible for an unprivileged user to create files
owned by any group in a tmpfs mount since it's possible to set the
setid bits on the tmpfs directory.
The contract for {g,u}id mount options and {g,u}id values in
general set from userspace has always been that they are translated
according to the caller's idmapping. In so far, tmpfs has been
doing the correct thing. But since tmpfs is mountable in
unprivileged contexts it is also necessary to verify that the
resulting {k,g}uid is representable in the namespace of the
superblock to avoid such bugs.
The new mount api's cross-namespace delegation abilities are
already widely used. Having talked to a bunch of userspace this is
the most faithful solution with minimal regression risks"

Pull vfs timestamp updates from Christian Brauner:
"This adds VFS support for multi-grain timestamps and converts tmpfs,
xfs, ext4, and btrfs to use them. This carries acks from all relevant
filesystems.
The VFS always uses coarse-grained timestamps when updating the ctime
and mtime after a change. This has the benefit of allowing filesystems
to optimize away a lot of metadata updates, down to around 1 per
jiffy, even when a file is under heavy writes.
Unfortunately, this has always been an issue when we're exporting via
NFSv3, which relies on timestamps to validate caches. A lot of changes
can happen in a jiffy, so timestamps aren't sufficient to help the
client decide to invalidate the cache.
Even with NFSv4, a lot of exported filesystems don't properly support
a change attribute and are subject to the same problems with timestamp
granularity. Other applications have similar issues with timestamps
(e.g., backup applications).
If we were to always use fine-grained timestamps, that would improve
the situation, but that becomes rather expensive, as the underlying
filesystem would have to log a lot more metadata updates.
This introduces fine-grained timestamps that are used when they are
actively queried.
This uses the 31st bit of the ctime tv_nsec field to indicate that
something has queried the inode for the mtime or ctime. When this flag
is set, on the next mtime or ctime update, the kernel will fetch a
fine-grained timestamp instead of the usual coarse-grained one.
As POSIX generally mandates that when the mtime changes, the ctime
must also change the kernel always stores normalized ctime values, so
only the first 30 bits of the tv_nsec field are ever used.
Filesytems can opt into this behavior by setting the FS_MGTIME flag in
the fstype. Filesystems that don't set this flag will continue to use
coarse-grained timestamps.
Various preparatory changes, fixes and cleanups are included:
- Fixup all relevant places where POSIX requires updating ctime
together with mtime. This is a wide-range of places and all
maintainers provided necessary Acks.
- Add new accessors for inode->i_ctime directly and change all
callers to rely on them. Plain accesses to inode->i_ctime are now
gone and it is accordingly rename to inode->__i_ctime and commented
as requiring accessors.
- Extend generic_fillattr() to pass in a request mask mirroring in a
sense the statx() uapi. This allows callers to pass in a request
mask to only get a subset of attributes filled in.
- Rework timestamp updates so it's possible to drop the @now
parameter the update_time() inode operation and associated helpers.
- Add inode_update_timestamps() and convert all filesystems to it
removing a bunch of open-coding"

Pull mount API updates from Christian Brauner:
"This introduces FSCONFIG_CMD_CREATE_EXCL which allows userspace to
implement something like
$ mount -t ext4 --exclusive /dev/sda /B
which fails if a superblock for the requested filesystem does already
exist instead of silently reusing an existing superblock.
Without it, in the sequence
$ move-mount -f xfs -o source=/dev/sda4 /A
$ move-mount -f xfs -o noacl,source=/dev/sda4 /B
the initial mounter will create a superblock. The second mounter will
reuse the existing superblock, creating a bind-mount (see [1] for the
source of the move-mount binary).
The problem is that reusing an existing superblock means all mount
options other than read-only and read-write will be silently ignored
even if they are incompatible requests. For example, the second mount
has requested no POSIX ACL support but since the existing superblock
is reused POSIX ACL support will remain enabled.
Such silent superblock reuse can easily become a security issue.
After adding support for FSCONFIG_CMD_CREATE_EXCL to mount(8) in
util-linux this can be fixed:
$ move-mount -f xfs --exclusive -o source=/dev/sda4 /A
$ move-mount -f xfs --exclusive -o noacl,source=/dev/sda4 /B
Device or resource busy | move-mount.c: 300: do_fsconfig: i xfs: reusing existing filesystem not allowed
This requires the new mount api. With the old mount api it would be
necessary to plumb this through every legacy filesystem's
file_system_type->mount() method. If they want this feature they are
most welcome to switch to the new mount api"

mlx5 HW can't perform IPsec offload operation simultaneously both on PF
and VFs at the same time. While the previous patches added devlink knobs
to change IPsec capabilities dynamically, there is a need to add a logic
to block such IPsec capabilities for the cases when IPsec is already
configured.

Expose port function commands to enable / disable IPsec packet offloads,
this is used to control the port IPsec capabilities.
When IPsec packet is disabled for a function of the port (default),
function cannot offload IPsec packet operations (encapsulation and XFRM
policy offload). When enabled, IPsec packet operations can be offloaded
by the function of the port, which includes crypto operation
(Encrypt/Decrypt), IPsec encapsulation and XFRM state and policy
offload.
Example of a PCI VF port which supports IPsec packet offloads:
$ devlink port show pci/0000:06:00.0/1
pci/0000:06:00.0/1: type eth netdev enp6s0pf0vf0 flavour pcivf pfnum 0 vfnum 0
function:

All users of plat->phylink_node first convert it to a fwnode. Rather
than repeatedly convert to a fwnode, store it as a fwnode. To reflect
this change, call it plat->port_node instead - it is used for more
than just phylink.

pull-request: bpf-next 2023-08-25
We've added 87 non-merge commits during the last 8 day(s) which contain
a total of 104 files changed, 3719 insertions(+), 4212 deletions(-).
The main changes are:
1) Add multi uprobe BPF links for attaching multiple uprobes
and usdt probes, which is significantly faster and saves extra fds,
from Jiri Olsa.
2) Add support BPF cpu v4 instructions for arm64 JIT compiler,
from Xu Kuohai.
3) Add support BPF cpu v4 instructions for riscv64 JIT compiler,
from Pu Lehui.
4) Fix LWT BPF xmit hooks wrt their return values where propagating
the result from skb_do_redirect() would trigger a use-after-free,
from Yan Zhai.
5) Fix a BPF verifier issue related to bpf_kptr_xchg() with local kptr
where the map's value kptr type and locally allocated obj type
mismatch, from Yonghong Song.
6) Fix BPF verifier's check_func_arg_reg_off() function wrt graph
root/node which bypassed reg->off == 0 enforcement,
from Kumar Kartikeya Dwivedi.
7) Lift BPF verifier restriction in networking BPF programs to treat
comparison of packet pointers not as a pointer leak,
from Yafang Shao.
8) Remove unmaintained XDP BPF samples as they are maintained
in xdp-tools repository out of tree, from Toke Høiland-Jørgensen.
9) Batch of fixes for the tracing programs from BPF samples in order
to make them more libbpf-aware, from Daniel T. Lee.
10) Fix a libbpf signedness determination bug in the CO-RE relocation
handling logic, from Andrii Nakryiko.
11) Extend libbpf to support CO-RE kfunc relocations. Also follow-up
fixes for bpf_refcount shared ownership implementation,
both from Dave Marchevsky.
12) Add a new bpf_object__unpin() API function to libbpf,
from Daniel Xu.
13) Fix a memory leak in libbpf to also free btf_vmlinux
when the bpf_object gets closed, from Hao Luo.
14) Small error output improvements to test_bpf module, from Helge Deller.
