Merge tag 'vfs-6.12.misc' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs

Pull misc vfs updates from Christian Brauner:
"This contains the usual pile of misc updates:

Features:

- Add F_CREATED_QUERY fcntl() that allows userspace to query whether
a file was actually created. Often userspace wants to know whether
an O_CREATE request did actually create a file without using
O_EXCL. The current logic is that to first attempts to open the
file without O_CREAT | O_EXCL and if ENOENT is returned userspace
tries again with both flags. If that succeeds all is well. If it
now reports EEXIST it retries.

That works fairly well but some corner cases make this more
involved. If this operates on a dangling symlink the first openat()
without O_CREAT | O_EXCL will return ENOENT but the second openat()
with O_CREAT | O_EXCL will fail with EEXIST.

The reason is that openat() without O_CREAT | O_EXCL follows the
symlink while O_CREAT | O_EXCL doesn't for security reasons. So
it's not something we can really change unless we add an explicit
opt-in via O_FOLLOW which seems really ugly.

All available workarounds are really nasty (fanotify, bpf lsm etc)
so add a simple fcntl().

- Try an opportunistic lookup for O_CREAT. Today, when opening a file
we'll typically do a fast lookup, but if O_CREAT is set, the kernel
always takes the exclusive inode lock. This was likely done with
the expectation that O_CREAT means that we always expect to do the
create, but that's often not the case. Many programs set O_CREAT
even in scenarios where the file already exists (see related
F_CREATED_QUERY patch motivation above).

The series contained in the pr rearranges the pathwalk-for-open
code to also attempt a fast_lookup in certain O_CREAT cases. If a
positive dentry is found, the inode_lock can be avoided altogether
and it can stay in rcuwalk mode for the last step_into.

- Expose the 64 bit mount id via name_to_handle_at()

Now that we provide a unique 64-bit mount ID interface in statx(2),
we can now provide a race-free way for name_to_handle_at(2) to
provide a file handle and corresponding mount without needing to
worry about racing with /proc/mountinfo parsing or having to open a
file just to do statx(2).

While this is not necessary if you are using AT_EMPTY_PATH and
don't care about an extra statx(2) call, users that pass full paths
into name_to_handle_at(2) need to know which mount the file handle
comes from (to make sure they don't try to open_by_handle_at a file
handle from a different filesystem) and switching to AT_EMPTY_PATH
would require allocating a file for every name_to_handle_at(2) call

- Add a per dentry expire timeout to autofs

There are two fairly well known automounter map formats, the autofs
format and the amd format (more or less System V and Berkley).

Some time ago Linux autofs added an amd map format parser that
implemented a fair amount of the amd functionality. This was done
within the autofs infrastructure and some functionality wasn't
implemented because it either didn't make sense or required extra
kernel changes. The idea was to restrict changes to be within the
existing autofs functionality as much as possible and leave changes
with a wider scope to be considered later.

One of these changes is implementing the amd options:
1) "unmount", expire this mount according to a timeout (same as
the current autofs default).
2) "nounmount", don't expire this mount (same as setting the
autofs timeout to 0 except only for this specific mount) .
3) "utimeout=<seconds>", expire this mount using the specified
timeout (again same as setting the autofs timeout but only for
this mount)

To implement these options per-dentry expire timeouts need to be
implemented for autofs indirect mounts. This is because all map
keys (mounts) for autofs indirect mounts use an expire timeout
stored in the autofs mount super block info. structure and all
indirect mounts use the same expire timeout.

Fixes:

- Fix missing fput for FSCONFIG_SET_FD in autofs

- Use param->file for FSCONFIG_SET_FD in coda

- Delete the 'fs/netfs' proc subtreee when netfs module exits

- Make sure that struct uid_gid_map fits into a single cacheline

- Don't flush in-flight wb switches for superblocks without cgroup
writeback

- Correcting the idmapping mount example in the idmapping
documentation

- Fix a race between evice_inodes() and find_inode() and iput()

- Refine the show_inode_state() macro definition in writeback code

- Prevent dump_mapping() from accessing invalid dentry.d_name.name

- Show actual source for debugfs in /proc/mounts

- Annotate data-race of busy_poll_usecs in eventpoll

- Don't WARN for racy path_noexec check in exec code

- Handle OOM on mnt_warn_timestamp_expiry()

- Fix some spelling in the iomap design documentation

- Fix typo in procfs comment

- Fix typo in fs/namespace.c comment

Cleanups:

- Add the VFS git tree to the MAINTAINERS file

- Move FMODE_UNSIGNED_OFFSET to fop_flags freeing up another f_mode
bit in struct file bringing us to 5 free f_mode bits

- Remove the __I_DIO_WAKEUP bit from i_state flags as we can simplify
the wait mechanism

- Remove the unused path_put_init() helper

- Replace a __u32 with u32 for s_fsnotify_mask as __u32 is uapi
specific

- Replace the unsigned long i_state member with a u32 i_state member
in struct inode freeing up 4 bytes in struct inode. Instead of
using the bit based wait apis we're now using the var event apis
and using the individual bytes of the i_state member to wait on
state changes

- Explain how per-syscall AT_* flags should be allocated

- Use in_group_or_capable() helper to simplify the posix acl mode
update code

- Switch to LIST_HEAD() in fsync_buffers_list() to simplify the code

- Removed comment about d_rcu_to_refcount() as that function doesn't
exist anymore

- Add kernel documentation for lookup_fast()

- Don't re-zero evenpoll fields

- Remove outdated comment after close_fd()

- Fix imprecise wording in comment about the pipe filesystem

- Drop GFP_NOFAIL mode from alloc_page_buffers

- Missing blank line warnings and struct declaration improved in
file_table

- Annotate struct poll_list with __counted_by()

- Remove the unused read parameter in percpu-rwsem

- Remove linux/prefetch.h include from direct-io code

- Use kmemdup_array instead of kmemdup for multiple allocation in
mnt_idmapping code

- Remove unused mnt_cursor_del() declaration

Performance tweaks:

- Dodge smp_mb in break_lease and break_deleg in the common case

- Only read fops once in fops_{get,put}()

- Use RCU in ilookup()

- Elide smp_mb in iversion handling in the common case

- Drop one lock trip in evict()"

KVM/arm64 updates for 6.12

* New features:

- Add a Stage-2 page table dumper, reusing the main ptdump
infrastructure, and allowing easier debugging of the our
page-table infrastructure

- Add FP8 support to the KVM/arm64 floating point handling.

- Add NV support for the AT family of instructions, which mostly
results in adding a page table walker that deals with most of the
complexity of the architecture.

* Improvements, fixes and cleanups:

- Add selftest checks for a bunch of timer emulation corner cases

- Fix the multiple of cases where KVM/arm64 doesn't correctly handle
the guest trying to use a GICv3 that isn't advertised

- Remove REG_HIDDEN_USER from the sysreg infrastructure, making
things little more simple

- Prevent MTE tags being restored by userspace if we are actively
logging writes, as that's a recipe for disaster

- Correct the refcount on a page that is not considered for MTE tag
copying (such as a device)

- Relax the synchronisation when walking a page table to split block
mappings, moving it at the end the walk, as there is no need to
perform it on every store.

- Fix boundary check when transfering memory using FFA

- Fix pKVM TLB invalidation, only affecting currently out of tree
code but worth addressing for peace of mind

According to bpftrace on these routines most calls result in cmpxchg,
which already provides the same guarantee.

In inode_maybe_inc_iversion elision is possible because even if the
wrong value was read due to now missing smp_mb fence, the issue is going
to correct itself after cmpxchg. If it appears cmpxchg wont be issued,
the fence + reload are there bringing back previous behavior.
