To: aalbersh, djwong; +Cc: linux-xfs
From: Darrick J. Wong <djwong@kernel.org>
This started with a desire to move the duplicate cmn_err declarations in
libxfs into libfrog/util.h ahead of the patch that renames libxfs_priv.h
to xfs_platform.h.
Then this patch expanded in scope when I realized that there were
several other utility functions that weren't specific to xfs; those go
in libfrog.

Source kernel commit: a48373e7d35a89f6f9b39f0d0da9bf158af054ee
Start creating helper functions and infrastructure to pass filesystem
health events to a health monitoring file. Since this is an
administrative interface, we only support a single health monitor
process per filesystem, so we don't need to use anything fancy such as
notifier chains (== tons of indirect calls).

Source kernel commit: b3a289a2a9397b2e731f334d7d36623a0f9192c5
Create the basic infrastructure that we need to report health events to
userspace. We need a compact form for recording critical information
about an event and queueing them; a means to notice that we've lost some
events; and a means to format the events into something that userspace
can handle. Make the kernel export C structures via read().
In a previous iteration of this new subsystem, I wanted to explore data
exchange formats that are more flexible and easier for humans to read
than C structures. The thought being that when we want to rev (or
worse, enlarge) the event format, it ought to be trivially easy to do
that in a way that doesn't break old userspace.
I looked at formats such as protobufs and capnproto. These look really
nice in that extending the wire format is fairly easy, you can give it a
data schema and it generates the serialization code for you, handles
endianness problems, etc. The huge downside is that neither support C
all that well.
Too hard, and didn't want to port either of those huge sprawling
libraries first to the kernel and then again to xfsprogs. Then I
thought, how about JSON? Javascript objects are human readable, the
kernel can emit json without much fuss (it's all just strings!) and
there are plenty of interpreters for python/rust/c/etc.
There's a proposed schema format for json, which means that xfs can
publish a description of the events that kernel will emit. Userspace
consumers (e.g. xfsprogs/xfs_healer) can embed the same schema document
and use it to validate the incoming events from the kernel, which means
it can discard events that it doesn't understand, or garbage being
emitted due to bugs.
However, json has a huge crutch -- javascript is well known for its
vague definitions of what are numbers. This makes expressing a large
number rather fraught, because the runtime is free to represent a number
in nearly any way it wants. Stupider ones will truncate values to word
size, others will roll out doubles for uint52_t (yes, fifty-two) with
the resulting loss of precision. Not good when you're dealing with
discrete units.
It just so happens that python's json library is smart enough to see a
sequence of digits and put them in a u64 (at least on x86_64/aarch64)
but an actual javascript interpreter (pasting into Firefox) isn't
necessarily so clever.
It turns out that none of the proposed json schemas were ever ratified
even in an open-consensus way, so json blobs are still just loosely
structured blobs. The parsing in userspace was also noticeably slow and
memory-consumptive.
Hence only the C interface survives.

Connect the fsdax media failure notification code to the health monitor
so that xfs can send events about that to the xfs_healer daemon.
Later on we'll add the ability for the xfs_scrub media scan (phase 6) to
report the errors that it finds to the kernel so that those are also
logged by xfs_healer.

Create a new ioctl for the healthmon file that checks that a given fd
points to the same filesystem that the healthmon file is monitoring.
This allows xfs_healer to check that when it reopens a mountpoint to
perform repairs, the file that it gets matches the filesystem that
generated the corruption report.
(Note that xfs_healer doesn't maintain an open fd to a filesystem that
it's monitoring so that it doesn't pin the mount.)

From: Darrick J. Wong <djwong@kernel.org>
Source kernel commit: b8accfd65d31f25b9df15ec2419179b6fa0b21d5
Add a new privileged ioctl so that xfs_scrub can ask the kernel to
verify the media of the devices backing an xfs filesystem, and have any
resulting media errors reported to fsnotify and xfs_healer.
To accomplish this, the kernel allocates a folio between the base page
size and 1MB, and issues read IOs to a gradually incrementing range of
one of the storage devices underlying an xfs filesystem. If any error
occurs, that raw error is reported to the calling process. If the error
happens to be one of the ones that the kernel considers indicative of
data loss, then it will also be reported to xfs_healthmon and fsnotify.
Driving the verification from the kernel enables xfs (and by extension
xfs_scrub) to have precise control over the size and error handling of
IOs that are issued to the underlying block device, and to emit
notifications about problems to other relevant kernel subsystems
immediately.
Note that the caller is also allowed to reduce the size of the IO and
to ask for a relaxation period after each IO.

Maybe use check_mul_overflow like the kernel version?
And avoid the overly long line and maybe even turn it into an inline?
I think it would also be cleared to split adding new core helpers into
a separate commit vs tagging it onto porting kernel code that's using
them.

Oh, yeah, I forgot that someone ported that to userspace.

Source kernel commit: cf9b52fa7d65362b648927d1d752ec99659f5c43
The xfs.h header conflicts with the public xfs.h in xfsprogs, leading
to a spurious difference in all shared libxfs files that have to
include libxfs_priv.h in userspace. Directly include xfs_platform.h so
that we can add a header of the same name to xfsprogs and remove this
major annoyance for the shared code.

From: Christoph Hellwig <hch@lst.de>
Source kernel commit: 3a65ea768b8094e4699e72f9ab420eb9e0f3f568
The calling convention of xfs_attr_leaf_hasname() is problematic, because
it returns a NULL buffer when xfs_attr3_leaf_read fails, a valid buffer
when xfs_attr3_leaf_lookup_int returns -ENOATTR or -EEXIST, and a
non-NULL buffer pointer for an already released buffer when
xfs_attr3_leaf_lookup_int fails with other error values.
Fix this by simply open coding xfs_attr_leaf_hasname in the callers, so
that the buffer release code is done by each caller of
xfs_attr3_leaf_read.
Fixes: 07120f1abdff ("xfs: Add xfs_has_attr and subroutines")

From: Christoph Hellwig <hch@lst.de>
Source kernel commit: 19c5b6051ed62d8c4b1cf92e463c1bcf629107f4
Currently xfs_zone_validate mixes validating the software zone state in
the XFS realtime group with validating the hardware state reported in
struct blk_zone and deriving the write pointer from that.
Move all code that works on the realtime group to xfs_init_zone, and only
keep the hardware state validation in xfs_zone_validate. This makes the
code more clear, and allows for better reuse in userspace.

FYI, I have a whole series to make better use of this new API in
xfs_repair. But I guess just doing the bulk conversion as part of the
sync might be ok. Looks quick from a first glance, but I've not 100%
verified it.

Source kernel commit: 6f13c1d2a6271c2e73226864a0e83de2770b6f34
Back in commit 2a2b5932db6758 ("xfs: fix attr leaf header freemap.size
underflow"), Brian Foster observed that it's possible for a small
freemap at the end of the end of the xattr entries array to experience
a size underflow when subtracting the space consumed by an expansion of
the entries array. There are only three freemap entries, which means
that it is not a complete index of all free space in the leaf block.
This code can leave behind a zero-length freemap entry with a nonzero
base. Subsequent setxattr operations can increase the base up to the
point that it overlaps with another freemap entry. This isn't in and of
itself a problem because the code in _leaf_add that finds free space
ignores any freemap entry with zero size.
However, there's another bug in the freemap update code in _leaf_add,
which is that it fails to update a freemap entry that begins midway
through the xattr entry that was just appended to the array. That can
result in the freemap containing two entries with the same base but
different sizes (0 for the "pushed-up" entry, nonzero for the entry
that's actually tracking free space). A subsequent _leaf_add can then
allocate xattr namevalue entries on top of the entries array, leading to
data loss. But fixing that is for later.
For now, eliminate the possibility of confusion by zeroing out the base
of any freemap entry that has zero size. Because the freemap is not
intended to be a complete index of free space, a subsequent failure to
find any free space for a new xattr will trigger block compaction, which
regenerates the freemap.
It looks like this bug has been in the codebase for quite a long time.

Source kernel commit: 3eefc0c2b78444b64feeb3783c017d6adc3cd3ce
xfs/592 and xfs/794 both trip this assertion in the leaf block freemap
adjustment code after ~20 minutes of running on my test VMs:
ASSERT(ichdr->firstused >= ichdr->count * sizeof(xfs_attr_leaf_entry_t)
+ xfs_attr3_leaf_hdr_size(leaf));
Upon enabling quite a lot more debugging code, I narrowed this down to
fsstress trying to set a local extended attribute with namelen=3 and
valuelen=71. This results in an entry size of 80 bytes.
At the start of xfs_attr3_leaf_add_work, the freemap looks like this:
i 0 base 448 size 0 rhs 448 count 46
i 1 base 388 size 132 rhs 448 count 46
i 2 base 2120 size 4 rhs 448 count 46
firstused = 520
where "rhs" is the first byte past the end of the leaf entry array.
This is inconsistent -- the entries array ends at byte 448, but
freemap[1] says there's free space starting at byte 388!
By the end of the function, the freemap is in worse shape:
i 0 base 456 size 0 rhs 456 count 47
i 1 base 388 size 52 rhs 456 count 47
i 2 base 2120 size 4 rhs 456 count 47
firstused = 440
Important note: 388 is not aligned with the entries array element size
of 8 bytes.
Based on the incorrect freemap, the name area starts at byte 440, which
is below the end of the entries array! That's why the assertion
triggers and the filesystem shuts down.
How did we end up here? First, recall from the previous patch that the
freemap array in an xattr leaf block is not intended to be a
comprehensive map of all free space in the leaf block. In other words,
it's perfectly legal to have a leaf block with:
* 376 bytes in use by the entries array
* freemap[0] has [base = 376, size = 8]
* freemap[1] has [base = 388, size = 1500]
* the space between 376 and 388 is free, but the freemap stopped
tracking that some time ago
If we add one xattr, the entries array grows to 384 bytes, and
freemap[0] becomes [base = 384, size = 0]. So far, so good. But if we
add a second xattr, the entries array grows to 392 bytes, and freemap[0]
gets pushed up to [base = 392, size = 0]. This is bad, because
freemap[1] hasn't been updated, and now the entries array and the free
space claim the same space.
The fix here is to adjust all freemap entries so that none of them
collide with the entries array. Note that this fix relies on commit
2a2b5932db6758 ("xfs: fix attr leaf header freemap.size underflow") and
the previous patch that resets zero length freemap entries to have
base = 0.

Check for erroneous overlapping freemap regions and collisions between
freemap regions and the xattr leaf entry array.
Note that we must explicitly zero out the extra freemaps in
xfs_attr3_leaf_compact so that the in-memory buffer has a correctly
initialized freemap array to satisfy the new verification code, even if
subsequent code changes the contents before unlocking the buffer.

Source kernel commit: d693534513d8dcdaafcf855986d0fe0476a47462
After a recent fsmark benchmarking run, I observed that the overhead of
parent pointers on file creation and deletion can be a bit high. On a
machine with 20 CPUs, 128G of memory, and an NVME SSD capable of pushing
750000iops, I see the following results:
$ mkfs.xfs -f -l logdev=/dev/nvme1n1,size=1g /dev/nvme0n1 -n parent=0
meta-data=/dev/nvme0n1 isize=512 agcount=40, agsize=9767586 blks
= sectsz=4096 attr=2, projid32bit=1
= crc=1 finobt=1, sparse=1, rmapbt=1
= reflink=1 bigtime=1 inobtcount=1 nrext64=1
= exchange=0 metadir=0
data = bsize=4096 blocks=390703440, imaxpct=5
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0, ftype=1, parent=0
log =/dev/nvme1n1 bsize=4096 blocks=262144, version=2
= sectsz=4096 sunit=1 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
= rgcount=0 rgsize=0 extents
= zoned=0 start=0 reserved=0
So we created 40 AGs, one per CPU. Now we create 40 directories and run
fsmark:
$ time fs_mark -D 10000 -S 0 -n 100000 -s 0 -L 8 -d ...
# Version 3.3, 40 thread(s) starting at Wed Dec 10 14:22:07 2025
# Sync method: NO SYNC: Test does not issue sync() or fsync() calls.
# Directories: Time based hash between directories across 10000 subdirectories with 180 seconds per subdirectory.
# File names: 40 bytes long, (16 initial bytes of time stamp with 24 random bytes at end of name)
# Files info: size 0 bytes, written with an IO size of 16384 bytes per write
# App overhead is time in microseconds spent in the test not doing file writing related system calls.

================== ==================
real 0m57.573s real 1m2.934s
user 3m53.578s user 3m53.508s

real 0m59.649s real 1m12.505s
user 0m41.196s user 0m47.489s
sys 13m9.566s sys 20m33.844s
Parent pointers increase the system time by 28% overhead to create 32
million files that are totally empty. Removing them incurs a system
time increase of 56%. Wall time increases by 9% and 22%.
For most filesystems, each file tends to have a single owner and not
that many xattrs. If the xattr structure is shortform, then all xattr
changes are logged with the inode and do not require the the xattr
intent mechanism to persist the parent pointer.
Therefore, we can speed up parent pointer operations by calling the
shortform xattr functions directly if the child's xattr is in short
format. Now the overhead looks like:
$ time fs_mark -D 10000 -S 0 -n 100000 -s 0 -L 8 -d ...
parent=0 parent=1
================== ==================
real 0m58.030s real 1m0.983s
user 3m54.141s user 3m53.758s
sys 19m57.003s sys 21m30.605s
$ time rm -rf ...
parent=0 parent=1
================== ==================
real 0m58.911s real 1m4.420s
user 0m41.329s user 0m45.169s
sys 13m27.857s sys 15m58.564s
Now parent pointers only increase the system time by 8% for creation and
19% for deletion. Wall time increases by 5% and 9% now.
Close the performance gap by creating helpers for the attr set, remove,
and replace operations that will try to make direct shortform updates,
and fall back to the attr intent machinery if that doesn't work. This
works for regular xattrs and for parent pointers.

Source kernel commit: eaec8aeff31d0679eadb27a13a62942ddbfd7b87
If we're trying to replace an xattr in a shortform attr structure and
the old entry fits the new entry, we can just memcpy and exit without
having to delete, compact, and re-add the entry (or worse use the attr
intent machinery). For parent pointers this only advantages renaming
where the filename length stays the same (e.g. mv autoexec.bat
scandisk.exe) but for regular xattrs it might be useful for updating
security labels and the like.

which is the only place that receives unvalidated error tag values from

Source kernel commit: 69050f8d6d075dc01af7a5f2f550a8067510366f
This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

Again, splitting out adding new helpers is probably a good idea.
And boy do I hate this new API that was just sneaked in without

FWIW I find this new helper rather pointless churn, especially since the
argument can be either a type or a pointer to a type. Great, we now no
longer have to type 'sizeof()', which is a boon because I now rent DRAM
by the byte.

From: Linus Torvalds <torvalds@linux-foundation.org>
Source kernel commit: bf4afc53b77aeaa48b5409da5c8da6bb4eff7f43
This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

Source kernel commit: 47553dd60b1da88df2354f841a4f71dd4de6478a
The active inode (or active vnode until recently) stat can get much larger
than expected on file systems with a lot of metafile inodes like zoned
file systems on SMR hard disks with 10.000s of rtg rmap inodes.
Remove all metafile inodes from the active counter to make it more useful
to track actual workloads and add a separate counter for active metafile
inodes.
This fixes xfs/177 on SMR hard drives.

Will do, though AFAICT all the previous "callsites" were all #ifdef'd

Add a comment explaining why the sb_frextents are updated outside the
if (xfs_has_lazycount(mp) check even though it is a lazycounter.
RT groups are supported only in v5 filesystems which always have
lazycounter enabled - so putting it inside the if(xfs_has_lazycount(mp)
check is redundant.

Source kernel commit: 650b774cf94495465d6a38c31bb1a6ce697b6b37
The ioctl structures in libxfs/xfs_fs.h are missing static size checks.
It is useful to have static size checks for these structures as adding
new fields to them could cause issues (e.g. extra padding that may be
inserted by the compiler). So add these checks to xfs/xfs_ondisk.h.
Due to different padding/alignment requirements across different
architectures, to avoid build failures, some structures are ommited from
the size checks. For example, structures with "compat_" definitions in
xfs/xfs_ioctl32.h are ommited.
