xfstest generic/221 is failing with delegated timestamps enabled. When
the client holds a WRITE_ATTRS_DELEG delegation, and a userland process
does a utimensat() for only the atime, the ctime is not properly
updated. The problem is that the client tries to cache the atime update,
but there is no mtime update, so the delegated attribute update never
updates the ctime.
Delegated timestamps don't have a mechanism to update the ctime in
accordance with atime-only changes due to utimensat() and the like.
Change the client to issue an RPC in this case, so that the ctime gets
properly updated alongside the atime.

When a pnfs error occurs, the IO is retried against the MDS. However,
the initial IO leads to the kernel logging "Serer wrote zero bytes"
when in fact the MDS IO will not fail and thus the error misleads
administrators that the system is experiencing issues.
When pnfs IO fails which triggers pnfs_write_done_resent_to_mds() which
would end up clearing nfs_pgio_header's pages structure (copying the
content into a new one to do new RPC calls to the MDS). Thus,
in nfs_writeback_result() when we have no pages to work with no need
to try and also therefore skip logging the message about 0bytes.

Pull vfs integrity updates from Christian Brauner:
"This adds support to generate and verify integrity information (aka
T10 PI) in the file system, instead of the automatic below the covers
support that is currently used.
The implementation is based on refactoring the existing block layer PI
code to be reusable for this use case, and then adding relatively
small wrappers for the file system use case. These are then used in
iomap to implement the semantics, and wired up in XFS with a small
amount of glue code.
Compared to the baseline this does not change performance for writes,
but increases read performance up to 15% for 4k I/O, with the benefit
decreasing with larger I/O sizes as even the baseline maxes out the
device quickly on my older enterprise SSD"

Pull vfs directory updates from Christian Brauner:
"Recently 'start_creating', 'start_removing', 'start_renaming' and
related interfaces were added which combine the locking and the
lookup.
At that time many callers were changed to use the new interfaces.
However there are still an assortment of places out side of the core
vfs where the directory is locked explictly, whether with inode_lock()
or lock_rename() or similar. These were missed in the first pass for
an assortment of uninteresting reasons.
This addresses the remaining places where explicit locking is used,
and changes them to use the new interfaces, or otherwise removes the
explicit locking.
The biggest changes are in overlayfs. The other changes are quite
simple, though maybe the cachefiles changes is the least simple of
those"

Pull vfs xattr updates from Christian Brauner:
"This reworks the simple_xattr infrastructure and adds support for
user.* extended attributes on sockets.
The simple_xattr subsystem currently uses an rbtree protected by a
reader-writer spinlock. This series replaces the rbtree with an
rhashtable giving O(1) average-case lookup with RCU-based lockless
reads. This sped up concurrent access patterns on tmpfs quite a bit
and it's an overall easy enough conversion to do and gets rid or
rwlock_t.
The conversion is done incrementally: a new rhashtable path is added
alongside the existing rbtree, consumers are migrated one at a time
(shmem, kernfs, pidfs), and then the rbtree code is removed. All three
consumers switch from embedded structs to pointer-based lazy
allocation so the rhashtable overhead is only paid for inodes that
actually use xattrs.
With this infrastructure in place the series adds support for user.*
xattrs on sockets. Path-based AF_UNIX sockets inherit xattr support
from the underlying filesystem (e.g. tmpfs) but sockets in sockfs -
that is everything created via socket() including abstract namespace
AF_UNIX sockets - had no xattr support at all.
The xattr_permission() checks are reworked to allow user.* xattrs on
S_IFSOCK inodes. Sockfs sockets get per-inode limits of 128 xattrs and
128KB total value size matching the limits already in use for kernfs.
The practical motivation comes from several directions. systemd and
GNOME are expanding their use of Varlink as an IPC mechanism.
For D-Bus there are tools like dbus-monitor that can observe IPC
traffic across the system but this only works because D-Bus has a
central broker.
For Varlink there is no broker and there is currently no way to
identify which sockets speak Varlink. With user.* xattrs on sockets a
service can label its socket with the IPC protocol it speaks (e.g.,
user.varlink=1) and an eBPF program can then selectively capture
traffic on those sockets. Enumerating bound sockets via netlink
combined with these xattr labels gives a way to discover all Varlink
IPC entrypoints for debugging and introspection.
Similarly, systemd-journald wants to use xattrs on the /dev/log socket
for protocol negotiation to indicate whether RFC 5424 structured
syslog is supported or whether only the legacy RFC 3164 format should
be used.
In containers these labels are particularly useful as high-privilege
or more complicated solutions for socket identification aren't
available.
The series comes with comprehensive selftests covering path-based
AF_UNIX sockets, sockfs socket operations, per-inode limit
enforcement, and xattr operations across multiple address families
(AF_INET, AF_INET6, AF_NETLINK, AF_PACKET)"

AMD PIIX4 SMBus adapters, present on AMD SP5/EPYC-based platforms
(including Cisco 8000 series routers), support SMBUS_BYTE_DATA and
SMBUS_WORD_DATA but lack I2C_FUNC_I2C and I2C_FUNC_SMBUS_I2C_BLOCK.
When at24 (or any driver) requests a regmap with reg_bits=16 and
val_bits=8 on such an adapter, regmap_get_i2c_bus() finds no matching
bus and returns -ENOTSUPP. The existing regmap_i2c_smbus_i2c_block_reg16
bus type already implements 16-bit addressed reads using only
write_byte_data() + read_byte() primitives, but its selection is gated
on I2C_FUNC_SMBUS_I2C_BLOCK which these adapters lack.
Add a new regmap_smbus_byte_word_reg16 bus that:
READ: reuses regmap_i2c_smbus_i2c_read_reg16() -- sets the 16-bit
address via write_byte_data(addr_lo, addr_hi), then reads
bytes sequentially via read_byte() (EEPROM auto-increments).
Requires only SMBUS_BYTE_DATA.
WRITE: uses write_word_data(addr_hi, (data << 8) | addr_lo) to
encode one data byte per SMBus WORD transaction.
Requires only SMBUS_WORD_DATA. Single-byte writes only.
The new bus is selected in regmap_get_i2c_bus() when reg_bits=16,
val_bits=8, and the adapter has SMBUS_BYTE_DATA | SMBUS_WORD_DATA but
not I2C_FUNC_I2C or SMBUS_I2C_BLOCK. The branch is placed after the
existing I2C_BLOCK_reg16 check so adapters with full block support
continue to use the faster path.
This fixes at24 EEPROM probe failures on PIIX4:
at24 3-0055: probe with driver at24 failed with error -524
No driver changes are required -- at24 already passes reg_bits=16 to
devm_regmap_init_i2c(), which now succeeds.

check_requires() compares requirement strings that can contain shell
pattern characters such as '[' and ']'. Under /bin/sh, the unquoted
test expressions can emit 'unexpected operator' warnings while parsing
README-backed requirements.
Quote the relevant comparisons and path checks so the helper handles
those patterns without spurious shell warnings.
Validated by rerunning fprobe_syntax_errors.tc and confirming the
previous '/bin/sh: unexpected operator' lines disappear from the
detailed ftracetest log.

Track failures explicitly in the top-level selftests all/install loops.
The current code multiplies `ret` by each sub-make exit status. For
example, with `TARGETS=net`, the implicit `net/lib` dependency runs after
`net`, so a failed `net` build can be followed by a successful `net/lib`
build and reset the final result to success.
Set `ret` to 1 on any non-zero sub-make exit code and keep it sticky, so
the top-level make returns failure when any selected selftest target
fails.

The --per-test-log option currently hard-codes /tmp. However, the system
under test will most likely have tmpfs mounted there. Since it's not clear
which filenames the log files will have, the user should be able to specify
a persistent directory to store the logs. Keeping those logs are important
because the run_kselftest.sh runner will only yield KTAP output, trimming
information that is otherwise available through running individual tests
directly.
Allow --per-test-log to take an optional directory argument. Keep the
existing behaviour when the option is passed without an argument, but if
a directory is provided, create it if needed, reject non-directory paths
and non-writable directories, canonicalize it, and have runner.sh write
per-test logs there instead of /tmp.
This also makes relative paths safe by resolving them before the runner
changes into a collection directory.

run_kselftest.sh only needs to canonicalize the directory containing the
script itself. Use shell-native path resolution for that by changing into
the directory and calling pwd -P.
This avoids depending on either realpath or readlink -f while still
producing a physical absolute path for BASE_DIR.

KVM SVM changes for 7.1
- Fix and optimize IRQ window inhibit handling for AVIC (the tracking needs to
be per-vCPU, e.g. so that KVM doesn't prematurely re-enable AVIC if multiple
vCPUs have to-be-injected IRQs).
- Fix an undefined behavior warning where a crafty userspace can read the
"avic" module param before it's fully initialized.
- Fix a (likely benign) bug in the "OS-visible workarounds" handling, where
KVM could clobber state when enabling virtualization on multiple CPUs in
parallel, and clean up and optimize the code.
- Drop a WARN in KVM_MEMORY_ENCRYPT_REG_REGION where KVM complains about a
"too large" size based purely on user input, and clean up and harden the
related pinning code.
- Disallow synchronizing a VMSA of an already-launched/encrypted vCPU, as
doing so for an SNP guest will trigger an RMP violation #PF and crash the
host.
- Protect all of sev_mem_enc_register_region() with kvm->lock to ensure
sev_guest() is stable for the entire of the function.
- Lock all vCPUs when synchronizing VMSAs for SNP guests to ensure the VMSA
page isn't actively being used.
- Overhaul KVM's APIs for detecting SEV+ guests so that VM-scoped queries are
required to hold kvm->lock (KVM has had multiple bugs due "is SEV?" checks
becoming stale), enforced by lockdep. Add and use vCPU-scoped APIs when
possible/appropriate, as all checks that originate from a vCPU are
guaranteed to be stable.
- Convert a pile of kvm->lock SEV code to guard().
