evict_folios() uses a second pass to reclaim folios that have gone through
page writeback and become clean before it finishes the first pass, since
folio_rotate_reclaimable() cannot handle those folios due to the
isolation.
The second pass tries to avoid potential double counting by deducting
scan_control->nr_scanned. However, this can result in underflow of
nr_scanned, under a condition where shrink_folio_list() does not increment
nr_scanned, i.e., when folio_trylock() fails.
The underflow can cause the divisor, i.e., scale=scanned+reclaimed in
vmpressure_calc_level(), to become zero, resulting in the following crash:
[exception RIP: vmpressure_work_fn+101]
process_one_work at ffffffffa3313f2b
Since scan_control->nr_scanned has no established semantics, the potential
double counting has minimal risks. Therefore, fix the problem by not
deducting scan_control->nr_scanned in evict_folios().

This mostly reverts commit af3b854492f3 ("mm/page_alloc.c: allow error
injection"). The commit made should_fail_alloc_page() a noinline function
that's always called from the page allocation hotpath, even if it's empty
because CONFIG_FAIL_PAGE_ALLOC is not enabled, and there is no option to
disable it and prevent the associated function call overhead.
As with the preceding patch "mm, slab: put should_failslab back behind
CONFIG_SHOULD_FAILSLAB" and for the same reasons, put the
should_fail_alloc_page() back behind the config option. When enabled, the
ALLOW_ERROR_INJECTION and BTF_ID records are preserved so it's not a
complete revert.

Patch series "revert unconditional slab and page allocator fault injection
calls".
These two patches largely revert commits that added function call overhead
into slab and page allocation hotpaths and that cannot be currently
disabled even though related CONFIG_ options do exist.
A much more involved solution that can keep the callsites always existing
but hidden behind a static key if unused, is possible [1] and can be
pursued by anyone who believes it's necessary. Meanwhile the fact the
should_failslab() error injection is already not functional on kernels
built with current gcc without anyone noticing [2], and lukewarm response
to [1] suggests the need is not there. I believe it will be more fair to
have the state after this series as a baseline for possible further
optimisation, instead of the unconditional overhead.
For example a possible compromise for anyone who's fine with an empty
function call overhead but not the full CONFIG_FAILSLAB /
CONFIG_FAIL_PAGE_ALLOC overhead is to reuse patch 1 from [1] but insert a
static key check only inside should_failslab() and
should_fail_alloc_page() before performing the more expensive checks.

This patch (of 2):
This mostly reverts commit 4f6923fbb352 ("mm: make should_failslab always
available for fault injection"). The commit made should_failslab() a
noinline function that's always called from the slab allocation hotpath,
even if it's empty because CONFIG_SHOULD_FAILSLAB is not enabled, and
there is no option to disable that call. This is visible in profiles and
the function call overhead can be noticeable especially with cpu
mitigations.
Meanwhile the bpftrace program example in the commit silently does not
work without CONFIG_SHOULD_FAILSLAB anyway with a recent gcc, because the
empty function gets a .constprop clone that is actually being called
(uselessly) from the slab hotpath, while the error injection is hooked to
the original function that's not being called at all [1].
Thus put the whole should_failslab() function back behind
CONFIG_SHOULD_FAILSLAB. It's not a complete revert of 4f6923fbb352 - the
int return type that returns -ENOMEM on failure is preserved, as well
ALLOW_ERROR_INJECTION annotation. The BTF_ID() record that was meanwhile
added is also guarded by CONFIG_SHOULD_FAILSLAB.

Syzbot reported a possible data race:
BUG: KCSAN: data-race in __swap_writepage / scan_swap_map_slots
read-write to 0xffff888102fca610 of 8 bytes by task 7106 on cpu 1.
read to 0xffff888102fca610 of 8 bytes by task 7080 on cpu 0.
While we are in __swap_writepage to read sis->flags, scan_swap_map_slots
is trying to update it with SWP_SCANNING.
value changed: 0x0000000000008083 -> 0x0000000000004083.
While this can be updated non-atomicially, this won't affect
SWP_SYNCHRONOUS_IO, so we consider this data-race safe.
This is possibly introduced by commit 3222d8c2a7f8 ("block: remove
->rw_page"), where this if branch is introduced.

than mmap_min_addr
generic_hugetlb_get_unmapped_area() was returning an address less than
mmap_min_addr if the mmap argument addr, after alignment, was less than
mmap_min_addr, causing mmap to fail.
This is because current generic_hugetlb_get_unmapped_area() code does not
take into account mmap_min_addr.
This patch ensures that generic_hugetlb_get_unmapped_area() always returns
an address that is greater than mmap_min_addr. Additionally, similar to
generic_get_unmapped_area(), vm_end_gap() checks are included to maintain
stack gap.
How to reproduce
================
#include <stdio.h>
#include <stdlib.h>
#include <sys/mman.h>
#include <unistd.h>
#define HUGEPAGE_SIZE (16 * 1024 * 1024)
int main() {
void *addr = mmap((void *)-1, HUGEPAGE_SIZE,
PROT_READ | PROT_WRITE,
MAP_SHARED | MAP_ANONYMOUS | MAP_HUGETLB, -1, 0);
if (addr == MAP_FAILED) {
perror("mmap");
exit(EXIT_FAILURE);
}
snprintf((char *)addr, HUGEPAGE_SIZE, "Hello, Huge Pages!");
printf("%s\n", (char *)addr);
if (munmap(addr, HUGEPAGE_SIZE) == -1) {
perror("munmap");
exit(EXIT_FAILURE);
}
return 0;
}
Result without fix
==================
# cat /proc/meminfo |grep -i HugePages_Free
HugePages_Free: 20
# ./test
mmap: Permission denied
#
Result with fix
===============
# cat /proc/meminfo |grep -i HugePages_Free
HugePages_Free: 20
# ./test
Hello, Huge Pages!

Pull ata updates from Niklas Cassel:
- ATA PASS-THROUGH sense data cleanups and fixes (Igor Pylypiv)
Store the sense data for ATA PASS-THROUGH commands at the correct
offset in the sense buffer when using fixed format sense data.
Cleanup the logic related to generating sense data for PASS-THROUGH
commands. Generating sense data for PASS-THROUGH commands would
overwrite any eventual (real) sense data received from the device.
Honor the D_SENSE bit when generating sense data for PASS-THROUGH
commands. (The D_SENSE bit can be set by the user, and determines if
the returned sense data should be in fixed format or descriptor
format)
- ata port allocation cleanups (me)
Assign the ata port print_id at port allocation time, such that the
ata_port_* print functions can be used earlier in the init call
chain.
Change the ata port port print_id to use ida_alloc(), such that
print_ids will get reused on rmmod + modprobe, instead of being
incremented indefinitely.
Remove wrappers that only existed in order to export the internal
libata functions which they wrapped, and instead export the libata
functions directly.
- Update SATA_MOBILE_LPM_POLICY Kconfig default to med_power_with_dipm
(Mario Limonciello)
Using this default was not always a good idea before, because it
would break hot plug support. However, with LPM changes in recent
kernels, a port marked as external will not enable LPM (in order to
not break hot plug), so it is now safe to change the default value of
this Kconfig.
All major Linux distros have had SATA_MOBILE_LPM_POLICY set to
med_power_with_dipm for quite a long time

Pull xfs updates from Chandan Babu:
"Major changes in this release are limited to enabling FITRIM on
realtime devices and Byte-based grant head log reservation tracking.
The remaining changes are limited to fixes and cleanups included in
this pull request.
Core:
- Enable FITRIM on the realtime device
- Introduce byte-based grant head log reservation tracking instead of
physical log location tracking.
This allows grant head to track a full 64 bit bytes space and hence
overcome the limit of 4GB indexing that has been present until now
Fixes:
- xfs_flush_unmap_range() and xfs_prepare_shift() should consider RT
extents in the flush unmap range
- Implement bounds check when traversing log operations during log
replay
- Prevent out of bounds access when traversing a directory data block
- Prevent incorrect ENOSPC when concurrently performing file creation
and file writes
- Fix rtalloc rotoring when delalloc is in use
Cleanups:
- Clean up I/O path inode locking helpers and the page fault handler
- xfs: hoist inode operations to libxfs in anticipation of the
metadata inode directory feature, which maintains a directory tree
of metadata inodes. This will be necessary for further enhancements
to the realtime feature, subvolume support
- Clean up some warts in the extent freeing log intent code
- Clean up the refcount and rmap intent code before adding support
for realtime devices
- Provide the correct email address for sysfs ABI documentation"
* tag 'xfs-6.11-merge-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (80 commits)
xfs: fix rtalloc rotoring when delalloc is in use
xfs: get rid of xfs_ag_resv_rmapbt_alloc
xfs: skip flushing log items during push
xfs: grant heads track byte counts, not LSNs
xfs: pass the full grant head to accounting functions
xfs: track log space pinned by the AIL
xfs: collapse xlog_state_set_callback in caller
xfs: l_last_sync_lsn is really AIL state
xfs: ensure log tail is always up to date
xfs: background AIL push should target physical space
xfs: AIL doesn't need manual pushing
xfs: move and rename xfs_trans_committed_bulk
xfs: fix the contact address for the sysfs ABI documentation
xfs: Avoid races with cnt_btree lastrec updates
xfs: move xfs_refcount_update_defer_add to xfs_refcount_item.c
xfs: simplify usage of the rcur local variable in xfs_refcount_finish_one
xfs: don't bother calling xfs_refcount_finish_one_cleanup in xfs_refcount_finish_one

Pull btrfs updates from David Sterba:
"The highlights are new logic behind background block group reclaim,
automatic removal of qgroup after removing a subvolume and new
'rescue=' mount options.
The rest is optimizations, cleanups and refactoring.
User visible features:
- dynamic block group reclaim:
- tunable framework to avoid situations where eager data
allocations prevent creating new metadata chunks due to lack of
unallocated space
- reuse sysfs knob bg_reclaim_threshold (otherwise used only in
zoned mode) for a fixed value threshold
- new on/off sysfs knob "dynamic_reclaim" calculating the value
based on heuristics, aiming to keep spare working space for
relocating chunks but not to needlessly relocate partially
utilized block groups or reclaim newly allocated ones
- stats are exported in sysfs per block group type, files
"reclaim_*"
- this may increase IO load at unexpected times but the corner
case of no allocatable block groups is known to be worse
- automatically remove qgroup of deleted subvolumes:
- adjust qgroup removal conditions, make sure all related
subvolume data are already removed, or return EBUSY, also take
into account setting of sysfs drop_subtree_threshold
- also works in squota mode
- mount option updates: new modes of 'rescue=' that allow to mount
images (read-only) that could have been partially converted by user
space tools
- ignoremetacsums - invalid metadata checksums are ignored
- ignoresuperflags - super block flags that track conversion in
progress (like UUID or checksums)
Core:
- size of struct btrfs_inode is now below 1024 (on a release config),
improved memory packing and other secondary effects
- switch tracking of open inodes from rb-tree to xarray, minor
performance improvement
- reduce number of empty transaction commits when there are no dirty
data/metadata
- memory allocation optimizations (reduced numbers, reordering out of
critical sections)
- extent map structure optimizations and refactoring, more sanity
checks
- more subpage in zoned mode preparations or fixes
- general snapshot code cleanups, improvements and documentation
- tree-checker updates: more file extent ram_bytes fixes, continued
- raid-stripe-tree update (not backward compatible):
- remove extent encoding field from the structure, can be inferred
from other information
- requires btrfs-progs 6.9.1 or newer
- cleanups and refactoring
- error message updates
- error handling improvements
- return type and parameter cleanups and improvements"

nfs_folio_length is unsafe to use without having the folio locked and a
check for a NULL ->f_mapping that protects against truncations and can
lead to kernel crashes. E.g. when running xfstests generic/065 with
all nfs trace points enabled.
Follow the model of the XFS trace points and pass in an explіcit offset
and length. This has the additional benefit that these values can
be more accurate as some of the users touch partial folio ranges.

The initial buffer has to be inited to all-ones, but it must restrict
it to the size of the first field, not the total field size.
After each round in the map search step, the result and the fill map
are swapped, so if we have a set where f->bsize of the first element
is smaller than m->bsize_max, those one-bits are leaked into future
rounds result map.
This makes pipapo find an incorrect matching results for sets where
first field size is not the largest.
Followup patch adds a test case to nft_concat_range.sh selftest script.
Thanks to Stefano Brivio for pointing out that we need to zero out
the remainder explicitly, only correcting memset() argument isn't enough.

When requesting an attestation report a guest is able to specify whether
it wants SNP firmware to sign the report using either a Versioned Chip
Endorsement Key (VCEK), which is derived from chip-unique secrets, or a
Versioned Loaded Endorsement Key (VLEK) which is obtained from an AMD
Key Derivation Service (KDS) and derived from seeds allocated to
enrolled cloud service providers (CSPs).
For VLEK keys, an SNP_VLEK_LOAD SNP firmware command is used to load
them into the system after obtaining them from the KDS. Add a
corresponding userspace interface so to allow the loading of VLEK keys
into the system.
See SEV-SNP Firmware ABI 1.54, SNP_VLEK_LOAD for more details.

aligned size of struct skb_shared_info.
On s390 the cacheline size is 256 bytes, and skb_shared_info minimum
size on 64 bits system is 320 bytes.
Avoid building the driver for such arch.

There is no support for HWPOISON, MEMORY_FAILURE, or ARCH_HAS_COPY_MC on
s390. Therefore we do not expect to see VM_FAULT_HWPOISON in
do_exception().
However, since commit af19487f00f3 ("mm: make PTE_MARKER_SWAPIN_ERROR more
general"), it is possible to see VM_FAULT_HWPOISON in combination with
PTE_MARKER_POISONED, even on architectures that do not support HWPOISON
otherwise. In this case, we will end up on the BUG() in do_exception().
Fix this by treating VM_FAULT_HWPOISON the same as VM_FAULT_SIGBUS, similar
to x86 when MEMORY_FAILURE is not configured. Also print unexpected fault
flags, for easier debugging.
Note that VM_FAULT_HWPOISON_LARGE is not expected, because s390 cannot
support swap entries on other levels than PTE level.

Instead of passing separate names and callbacks arrays
to virtio_find_vqs(), have one of virtual_queue_info structs and
pass it to virtio_find_vqs_info().
