Pull landlock updates from Mickaël Salaün:
"This adds file truncation support to Landlock, contributed by Günther
Noack. As described by Günther [1], the goal of these patches is to
work towards a more complete coverage of file system operations that
are restrictable with Landlock.
The known set of currently unsupported file system operations in
Landlock is described at [2]. Out of the operations listed there,
truncate is the only one that modifies file contents, so these patches
should make it possible to prevent the direct modification of file
contents with Landlock.
The new LANDLOCK_ACCESS_FS_TRUNCATE access right covers both the
truncate(2) and ftruncate(2) families of syscalls, as well as open(2)
with the O_TRUNC flag. This includes usages of creat() in the case
where existing regular files are overwritten.
Additionally, this introduces a new Landlock security blob associated
with opened files, to track the available Landlock access rights at
the time of opening the file. This is in line with Unix's general
approach of checking the read and write permissions during open(), and
associating this previously checked authorization with the opened
file. An ongoing patch documents this use case [3].
In order to treat truncate(2) and ftruncate(2) calls differently in an
LSM hook, we split apart the existing security_path_truncate hook into
security_path_truncate (for truncation by path) and
security_file_truncate (for truncation of previously opened files)"

In Kbuild, some files are generated by chains of pattern/implicit rules.
For example, *.dtb.o files in drivers/of/unittest-data/Makefile are
generated by the chain of 3 pattern rules, like this:
%.dts -> %.dtb -> %.dtb.S -> %.dtb.o
Here, %.dts is the real source, %.dtb.o is the final target.
%.dtb and %.dtb.S are called "intermediate files".
As GNU Make manual [1] says, intermediate files are treated differently
in two ways:
(a) The first difference is what happens if the intermediate file does
not exist. If an ordinary file 'b' does not exist, and make considers
a target that depends on 'b', it invariably creates 'b' and then
updates the target from 'b'. But if 'b' is an intermediate file, then
make can leave well enough alone: it won't create 'b' unless one of
its prerequisites is out of date. This means the target depending
on 'b' won't be rebuilt either, unless there is some other reason
to update that target: for example the target doesn't exist or a
different prerequisite is newer than the target.
(b) The second difference is that if make does create 'b' in order to
update something else, it deletes 'b' later on after it is no longer
needed. Therefore, an intermediate file which did not exist before
make also does not exist after make. make reports the deletion to
you by printing a 'rm' command showing which file it is deleting.
The combination of these is problematic for Kbuild because most of the
build rules depend on FORCE and the if_changed* macros really determine
if the target should be updated. So, all missing files, whether they
are intermediate or not, are always rebuilt.
To see the problem, delete ".SECONDARY:" from scripts/Kbuild.include,
and repeat this command:
$ make allmodconfig drivers/of/unittest-data/
The intermediate files will be deleted, which results in rebuilding
intermediate and final objects in the next run of make.
In the old days, people suppressed (b) in inconsistent ways.
As commit 54a702f70589 ("kbuild: mark $(targets) as .SECONDARY and
remove .PRECIOUS markers") noted, you should not use .PRECIOUS because
.PRECIOUS has the following behavior (c), which is not likely what you
want.
(c) If make is killed or interrupted during the execution of their
recipes, the target is not deleted. Also, the target is not deleted
on error even if .DELETE_ON_ERROR is specified.
.SECONDARY is a much better way to disable (b), but a small problem
is that .SECONDARY enables (a), which gives a side-effect to $?;
prerequisites marked as .SECONDARY do not appear in $?. This is a
drawback for Kbuild.
I thought it was a bug and opened a bug report. As Paul, the GNU Make
maintainer, concluded in [2], this is not a bug.
A good news is that, GNU Make 4.4 added the perfect solution,
.NOTINTERMEDIATE, which cancels both (a) and (b).
For clarificaton, my understanding of .INTERMEDIATE, .SECONDARY,
.PRECIOUS and .NOTINTERMEDIATE are as follows:
(a) (b) (c)
.INTERMEDIATE enable enable disable
.SECONDARY enable disable disable
.PRECIOUS disable disable enable
.NOTINTERMEDIATE disable disable disable
However, GNU Make 4.4 has a bug for the global .NOTINTERMEDIATE. [3]
It was fixed by commit 6164608900ad ("[SV 63417] Ensure global
.NOTINTERMEDIATE disables all intermediates"), and will be available
in the next release of GNU Make.
The following is the gain for .NOTINTERMEDIATE:

GNU Make 4.4 introduced $(intcmp ...), which is useful to compare two
integers without forking a new process.
Add test-{ge,gt,le,lt} macros, which work more efficiently with GNU
Make >= 4.4. For older Make versions, they fall back to the 'test'
shell command.
The first two parameters to $(intcmp ...) must not be empty. To avoid
the syntax error, I appended '0' to them. Fortunately, '00' is treated
as '0'. This is needed because CONFIG options may expand to an empty
string when the kernel configuration is not included.

RISC-V kernels support 3,4,5-level page tables at runtime by folding
upper levels.
In case of a 3-level page table, PGDIR is folded into P4D which in turn
is folded into PUD: PGDIR_SHIFT value is correctly set to the same value
as PUD_SHIFT, but P4D_SHIFT is not, then any use of P4D_SHIFT will access
invalid address bits (all set to 1).
Fix this by dynamically defining P4D_SHIFT value, like we already do for
PGDIR_SHIFT.

Pull nfsd updates from Chuck Lever:
"This release introduces support for the CB_RECALL_ANY operation. NFSD
can send this operation to request that clients return any delegations
they choose. The server uses this operation to handle low memory
scenarios or indicate to a client when that client has reached the
maximum number of delegations the server supports.
The NFSv4.2 READ_PLUS operation has been simplified temporarily whilst
support for sparse files in local filesystems and the VFS is improved.
Two major data structure fixes appear in this release:
- The nfs4_file hash table is replaced with a resizable hash table to
reduce the latency of NFSv4 OPEN operations.
- Reference counting in the NFSD filecache has been hardened against
races.
In furtherance of removing support for NFSv2 in a subsequent kernel
release, a new Kconfig option enables server-side support for NFSv2 to
be left out of a kernel build.
MAINTAINERS has been updated to indicate that changes to fs/exportfs
should go through the NFSD tree"

Pull btrfs updates from David Sterba:
"This round there are a lot of cleanups and moved code so the diffstat
looks huge, otherwise there are some nice performance improvements and
an update to raid56 reliability.
User visible features:
- raid56 reliability vs performance trade off:
- fix destructive RMW for raid5 data (raid6 still needs work): do
full checksum verification for all data during RMW cycle, this
should prevent rewriting potentially corrupted data without
notice
- stripes are cached in memory which should reduce the performance
impact but still can hurt some workloads
- checksums are verified after repair again
- this is the last option without introducing additional features
(write intent bitmap, journal, another tree), the extra checksum
read/verification was supposed to be avoided by the original
implementation exactly for performance reasons but that caused
all the reliability problems
- discard=async by default for devices that support it
- implement emergency flush reserve to avoid almost all unnecessary
transaction aborts due to ENOSPC in cases where there are too many
delayed refs or delayed allocation
- skip block group synchronization if there's no change in used
bytes, can reduce transaction commit count for some workloads
Performance improvements:
- fiemap and lseek:
- overall speedup due to skipping unnecessary or duplicate
searches (-40% run time)
- cache some data structures and sharedness of extents (-30% run
time)
- send:
- faster backref resolution when finding clones
- cached leaf to root mapping for faster backref walking
- improved clone/sharing detection
- overall run time improvements (-70%)
Core:
- module initialization converted to a table of function pointers run
in a sequence
- preparation for fscrypt, extend passing file names across calls,
dir item can store encryption status
- raid56 updates:
- more accurate error tracking of sectors within stripe
- simplify recovery path and remove dedicated endio worker kthread
- simplify scrub call paths
- refactoring to support the extra data checksum verification
during RMW cycle
- tree block parentness checks consolidated and done at metadata read
time
- improved error handling
- cleanups:
- move a lot of code for better synchronization between kernel and
user space sources, split big files
- enum cleanups
- GFP flag cleanups
- header file cleanups, prototypes, dependencies
- redundant parameter cleanups
- inline extent handling simplifications

Pull xattr audit fix from Seth Forshee:
"This is a single patch to remove auditing of the capability check in
simple_xattr_list().
This check is done to check whether trusted xattrs should be included
by listxattr(2). SELinux will normally log a denial when capable() is
called and the task's SELinux context doesn't have the corresponding
capability permission allowed, which can end up spamming the log.
Since a failed check here cannot be used to infer malicious intent,
auditing is of no real value, and it makes sense to stop auditing the
capability check"

Pull erofs updates from Gao Xiang:
"In this cycle, large folios are now enabled in the iomap/fscache mode
for uncompressed files first. In order to do that, we've also cleaned
up better interfaces between erofs and fscache, which are acked by
fscache/netfs folks and included in this pull request.
Other than that, there are random fixes around erofs over fscache and
crafted images by syzbot, minor cleanups and documentation updates.
Summary:
- Enable large folios for iomap/fscache mode
- Avoid sysfs warning due to mounting twice with the same fsid and
domain_id in fscache mode
- Refine fscache interface among erofs, fscache, and cachefiles
- Use kmap_local_page() only for metabuf
- Fixes around crafted images found by syzbot
- Minor cleanups and documentation updates"

Pull fscrypt updates from Eric Biggers:
"This release adds SM4 encryption support, contributed by Tianjia
Zhang. SM4 is a Chinese block cipher that is an alternative to AES.
I recommend against using SM4, but (according to Tianjia) some people
are being required to use it. Since SM4 has been turning up in many
other places (crypto API, wireless, TLS, OpenSSL, ARMv8 CPUs, etc.),
it hasn't been very controversial, and some people have to use it, I
don't think it would be fair for me to reject this optional feature.
Besides the above, there are a couple cleanups"

KCSAN reported a race between writing req->status in p9_client_cb and
accessing it in p9_client_rpc's wait_event.
Accesses to req itself is protected by the data barrier (writing req
fields, write barrier, writing status // reading status, read barrier,
reading other req fields), but status accesses themselves apparently
also must be annotated properly with WRITE_ONCE/READ_ONCE when we
access it without locks.
Follows:
- error paths writing status in various threads all can notify
p9_client_rpc, so these all also need WRITE_ONCE
- there's a similar read loop in trans_virtio for zc case that also
needs READ_ONCE
- other reads in trans_fd should be protected by the trans_fd lock and
lists state machine, as corresponding writers all are within trans_fd
and should be under the same lock. If KCSAN complains on them we likely
will have something else to fix as well, so it's better to leave them
unmarked and look again if required.
