of: Fix RST inline emphasis warnings in of_map_id() kernel-doc
The @filter_np parameter descriptions in of_map_id() and of_map_msi_id() contained the text '*filter_np' in prose. Docutils interprets a leading '*' as the start of RST emphasis (italic), but finds no closing '*', triggering: Documentation/devicetree/kernel-api:11: ./drivers/of/base.c:2134: WARNING: Inline emphasis start-string without end-string. [docutils] Documentation/devicetree/kernel-api:11: ./drivers/of/base.c:2260: WARNING: Inline emphasis start-string without end-string. [docutils] Fix by wrapping '*filter_np' in double backticks (*filter_np) to render it as an RST inline code literal, which is also the correct kernel-doc convention for pointer expressions.

of: property: Fix of_fwnode_get_reference_args() with negative index
fwnode_property_get_reference_args() should return -ENOENT when an out
of bound index is passed. An issue arised with the OF backend because
the OF API use signed indexes while the fwnode API use unsigned ones.
When an index value greater the INT_MAX was passed to the OF backend
it got casted to a negative value and it returned -EINVAL instead of
-ENOENT. This patch add a check to of_fwnode_get_reference_args() to
catch negative index before they are passed to the OF API and return
-ENOENT right away.
This issue appeared when the following pattern was used in the LED
subsystem:
index = fwnode_property_match_string(fwnode, "led-names", name)
led_node = fwnode_find_reference(fwnode, "leds", index);
Unlike the same pattern with the OF API, this pattern implicitly cast
the signed return value of fwnode_property_match_string() to an
unsigned index leading to the above issue with the OF backend. It can
be argued that the return value of fwnode_property_match_string()
should be checked separately, but I think there is value in supporting
such simple and straight to the point patterns.

f2fs-for-7.2-rc1
In this round, the changes primarily focus on filesystem error reporting, reducing memory footprint by reverting in-memory data structures used for runtime validation, honoring FDP hints, and adding trace and debug logs. In addition, there are critical bug fixes resolving out-of-bounds read vulnerabilities in inline directory and ACL handling, potential deadlocks in balance_fs, use-after-free issues in atomic writes, and false data/node type assignments in large sections. Enhancement: - Revert in-memory sit version and block bitmaps - support to report fserror - add trace_f2fs_fault_report - add iostat latency tracking for direct IO - add logs in f2fs_disable_checkpoint() - honor per-I/O write streams for direct writes - map data writes to FDP streams - skip inode folio lookup for cached overwrite - skip direct I/O iostat context when disabled - revert "check in-memory block bitmap" - revert "check in-memory sit version bitmap" Bug fix: - optimize representative type determination in GC - fix incorrect FI_NO_EXTENT handling in __destroy_extent_node() - fix potential deadlock in f2fs_balance_fs() - fix potential deadlock in gc_merge path of f2fs_balance_fs() - atomic: fix UAF issue on f2fs_inode_info.atomic_inode - fix missing read bio submission on large folio error - pass correct iostat type for single node writes - fix to do sanity check on f2fs_get_node_folio_ra() - validate orphan inode entry count - keep atomic write retry from zeroing original data - read COW data with the original inode during atomic write - validate inline dentry name lengths before conversion - validate dentry name length before lookup compares it - reject setattr size changes on large folio files - revert "remove non-uptodate folio from the page cache in move_data_block" - validate ACL entry sizes in f2fs_acl_from_disk() - bound i_inline_xattr_size for non-inline-xattr inodes - fix listxattr handling of corrupted xattr entries - fix to round down start offset of fallocate for pin file -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAmo5sQwACgkQQBSofoJI UNIB7g/+IMAr2UVWdpZ88Uho58GvkkIuZceoZoPuSfUi1hTy0o4+wxeo2ecO06v6 pDlxivkWXRDpdW1iXbUqcmk2HKEsM3ysWb6jvsFXz+eC4QeWKQJ2uZTyLpEVpW2j phXv3TwENPEkku2Mncv907hqUZG/SBxJ2H7jcxb0jHRoaLUwZHuGF0VU/MEodyuy ZJifGI3BMwm7Gu2GXwuliDBjbUHRaBs+8kYQ21NZGv0FuQsCNQ+bLhWz3q4FVfg6 nt5FStKgfoKPHIhamltP6uc4E4KlNDtFgKxluEfzrVqxqvHvUpBxj718DtZLbpNN zD6PUHCI0MU0L7qW+RVJx8TOaceYB5xHVcNi8d+CDQPCJgG0LV0ilykqzQ4LRSob JcPIjEVkrIgNSzYh/PcDHkUBZmt3MiZZf6xaxviqxDoPqyY6TFATF27ZIZbc7jSa hF4XO6mNtbDLhSIMrFUXBnGfnKvIK42OyM5aFLEMxBm7akYYr64h+r6mR+apjDb1 4FQ1YIuKfIHm7DuphUiazmyOV7P4kcOGYbqyiOk/HNxf6Cc3/kOXKTRZq00ORNbX X0FXUOy94xrrjdqoWTldv2o4I49zf8RAEBNLAxDneV2qXsITQtsHWUXp5BbKdA0Q 7nyUBUTOdDvUq3qyXXA9BIKWdTr0XeGGp/z8rrVR0aT6ksqiTzM= =YvkR -----END PGP SIGNATURE----- Merge tag 'f2fs-for-7.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "The changes primarily focus on filesystem error reporting, reducing memory footprint by reverting in-memory data structures used for runtime validation, honoring FDP hints, and adding trace and debug logs.

perf tools changes for v7.2:
- Introduce 'perf inject --aslr' to remap ASLR-randomized addresses in perf.data files, enabling reproducible analysis across runs with different address space layouts. - Refactor evsel out of sample processing paths: store evsel in struct perf_sample and remove the redundant evsel parameter from tool APIs, tracepoint handlers, hist entry iterators, and db-export, simplifying the entire tool callback chain. - Switch architecture detection from string-based perf_env__arch() comparisons to the numeric ELF e_machine field across the codebase (capstone, print_insn, c2c, lock-contention, sort, sample-raw, machine, header), making cross-analysis more robust. - Overhaul ARM CoreSight ETM tests: add deterministic and named_threads workloads, speed up basic and disassembly tests, add process attribution and concurrent threads tests, remove unused workloads and duplicate tests, queue context packets for the frontend decoder. - Add ARM SPE IMPDEF event decoding for Arm Neoverse N1, store MIDR in arm_spe_pkt for per-CPU event mapping, handle missing CPU IDs gracefully. - Refactor libunwind support: remove the libunwind-local backend, make register reading cross-platform, add RISC-V libunwind support, allow dynamic selection between libdw and libunwind unwinding at runtime. - Extensive hardening of perf.data parsing against crafted files: add bounds checks and byte-swap validation for session records, feature sections, header attributes, BPF metadata, auxtrace errors, compressed events, CPU maps, build ID notes, and ELF program headers. Add minimum event size validation and file offset diagnostics. - Fix libdw API contract violations across dwarf-aux, libdw, probe-finder, annotate-data, and debuginfo subsystems. Fix callchain parent update in ORDER_CALLER mode, support DWARF line 0 in inline lists, handle multiple address spaces in callchains. - Fix numerous 'perf sched' bugs: thread reference leaks, memory leaks, heap overflows with cross-machine recordings, NULL dereferences, replace BUG_ON assertions with graceful error handling, bounds-check CPU indices, fix SIGCHLD vs pause() races in sched stats. - Overhaul the build system: move BPF skeleton generation out of Makefile.perf into bpf_skel.mak, decouple pmu-events from the prepare target, make beauty generated C code standalone .o files, compile BPF skeletons with -mcpu=v3, fix continuous rebuilds, various cleanups. - Add 'perf test' JUnit XML reporting with -j/--junit option, split monolithic test suites into sub-tests, add summary reporting, refactor parallel poll loop, fix test failures on musl-based systems. - Fix 'perf c2c' memory leaks in hist entry and format list handling, use-after-free in error paths, bounds-check CPU and node IDs. - Fix 'perf bpf' metadata leaks on duplicate insert and alloc failure, bounds-check array offsets, validate event sizes and func_info fields, add NULL checks. - Fix hwmon PMU: off-by-one null termination on sysfs reads, strlcpy buffer overflow in parse_hwmon_filename(), fd 0 check, empty label reads, scnprintf usage. - Fix symbols subsystem: bounds-check ELF and sysfs build ID note iteration, validate p_filesz, fix 32-bit ELF bswap error, fix signed overflow in size checks, bounds-check .gnu_debuglink section. - Fix tools lib api: null termination in filename__read_int/ull(), uninitialized stack data in filename__write_int(), snprintf truncation in mount_overload(). - Replace libbabeltrace with babeltrace2-ctf-writer for CTF conversion in 'perf data'. - Add RISC-V SDT argument parsing for static tracepoints. - Add 'perf trace --show-cpu' option to display CPU id. - Add 'perf bench sched pipe --write-size' option. - Add a perf-specific .clang-format that overrides some kernel style behaviors. - Update Intel vendor events for Alder Lake, Arrow Lake, Clearwater Forest, Emerald Rapids, Granite Rapids, Grand Ridge, Lunar Lake, Meteor Lake, Panther Lake, Sapphire Rapids, Sierra Forest. - Add IOMMU metrics for AMD and Intel. - Fix AMD event: switch l2_itlb_misses to bp_l1_tlb_miss_l2_tlb_miss.all. - Add AMD IBS improvements: decode Streaming-store and Remote-Socket flags, suppress bogus fields on Zen4+, skip privilege test on Zen6+. - Fix 'perf lock contention' SIGCHLD vs pause() race, allow 'mmap_lock' in -L filter, enable end-timestamp for cgroup aggregation, fix non-atomic data updates. - Fix 'perf stat' false NMI watchdog warning in aggregation modes, bounds-check CPU index in topology callbacks, add aggr_nr metric parser support for uncore scaling. - Fix 'perf timechart' memory leaks, CPU bounds checking, use-after-free on corrupted callchains. - Fix 'perf inject' itrace branch stack synthesis, fix synthesized sample size with branch stacks. - Fix DSO heap overflow on decompressed paths, uninitialized pathname on fallback, set proper error codes. - Fix various snprintf/scnprintf usages to prevent buffer overflows and truncation across the codebase. - Fix off-by-one stack buffer overflow in kallsyms__parse(). - Fix 'perf kwork' memory management, address sanitizer issues, bounds check work->cpu. - Fix 'perf tpebs' concurrent stop races and PID reuse hazards. - Add O_CLOEXEC to open() calls and use mkostemp() for temporary files to prevent file descriptor leaks to child processes. - Fix s390 Python extension TEXTREL by compiling as PIC. - Fix build with ASAN for jitdump. - Fix build failure due to btf_vlen() return type change.

Pull erofs updates from Gao Xiang:
"The most notable change is the removal of the fscache backend: it has
been deprecated for almost two years, mainly because EROFS file-backed
mounts and fanotify pre-content hooks (together with erofs-utils) now
provide better functionality and simpler codebase. In addition,
fscache has depended on netfslib for years, which is undesirable for
EROFS since it is a local filesystem. More details in [1].
In addition, sparse support has been added to the pcluster layout,
which is helpful for large sparse AI datasets, and map requests for
chunk-based inodes have been optimized to be more efficient as well.
There are also the usual fixes and cleanups.
Summary:
- Report more consecutive chunks of the same type for

- Add sparse support for the pcluster layout
- Update the EROFS documentation overview

idle.c and cid.c are included into build_policy.c together with ext.c and use helpers that ext.c defines.

sched_ext: Make kernel/sched/ext/ sources self-contained for clangd
The sources under kernel/sched/ext/ build as a single translation unit: build_policy.c includes the source files and headers. An LSP/clangd editor parses each as a standalone unit, sees no types, and reports a flood of errors. Give each header its dependencies and include guard, and have each source include the headers it uses. ext.c, arena.c and the ext headers now parse clean standalone. idle.c and cid.c still reference a few macros and helpers defined in ext.c.

f2fs: fix to round down start offset of fallocate for pin file
Currently, the length of fallocate for pin file is section-aligned to
keep allocated sections from being selected as victims of GC. However,
for the case that the start offset of fallocate is not aligned in
section, the allocated sections can't be fully utilized. It's because a
new section is allocated by f2fs_allocate_pinning_section() after using
blks_per_sec blocks regardless of the start offset. As a result, several
unexpected dirty segments may be created, including blocks assigned to
the pinned file.
To address this issue, let's round down the start offset of fallocate
to the length of section.
The reproducing scenario is as below
chunk=$(((2<<20)+4096)) # 2MB + 4KB
touch test
f2fs_io pinfile set test
f2fs_io fallocate 0 0 $chunk test
f2fs_io fallocate 0 $chunk $chunk test
f2fs_io fallocate 0 $((chunk*2)) $chunk test
f2fs_io fiemap 0 $((chunk*3)) test
Fiemap: offset = 0 len = 12288

f2fs: skip direct I/O iostat context when disabled
F2FS iostat is optional and is disabled by default. Direct I/O still
allocates and binds a bio_iostat_ctx, updates the submit timestamp, and
replaces bi_end_io for every DIO bio even when sbi->iostat_enable is
false.
The byte accounting calls do not need an extra guard because
f2fs_update_iostat() already checks sbi->iostat_enable. Only skip the
DIO bio context setup when iostat is disabled. If iostat is enabled
through sysfs before submission, the existing context allocation and
latency accounting path is still used.
QEMU benchmark on a 1GiB F2FS virtio-blk image, with iostat_enable=0,
4KiB O_DIRECT I/O over a 64MiB file, 50000 iterations per run:
baseline patched
direct_read median 65264.50 ns 55470.95 ns
direct_read recheck 65553.75 ns 55470.95 ns

f2fs: bound i_inline_xattr_size for non-inline-xattr inodes
When the flexible_inline_xattr feature is enabled, do_read_inode() loads
the on-disk i_inline_xattr_size unconditionally:
if (f2fs_sb_has_flexible_inline_xattr(sbi))
fi->i_inline_xattr_size = le16_to_cpu(ri->i_inline_xattr_size);
but sanity_check_inode() only range-checks it when the inode also has the
FI_INLINE_XATTR flag set. An inode that carries an inline dentry or inline
data but not FI_INLINE_XATTR -- the normal layout for an inline
directory -- therefore keeps a fully attacker-controlled
i_inline_xattr_size from a crafted image.
get_inline_xattr_addrs() returns that value with no flag gating, so it
feeds the inode geometry:
MAX_INLINE_DATA() = 4 * (CUR_ADDRS_PER_INODE - i_inline_xattr_size - 1)
NR_INLINE_DENTRY() = MAX_INLINE_DATA() * BITS_PER_BYTE / (...)
addrs_per_page() = CUR_ADDRS_PER_INODE - i_inline_xattr_size
A large i_inline_xattr_size drives MAX_INLINE_DATA() and NR_INLINE_DENTRY()
negative, so make_dentry_ptr_inline() sets d->max (int) to a negative
value. The inline directory walk then compares an unsigned long bit_pos
against that negative d->max, which is promoted to a huge unsigned bound,
and reads far past the inline area:
while (bit_pos < d->max) /* fs/f2fs/dir.c */
... test_bit_le(bit_pos, d->bitmap) / d->dentry[bit_pos] ...
Mounting a crafted image and reading such a directory triggers an
out-of-bounds read in f2fs_fill_dentries(); the same underflow also
corrupts ADDRS_PER_INODE for regular files.
Validate i_inline_xattr_size against MAX_INLINE_XATTR_SIZE whenever the
flexible_inline_xattr feature is enabled -- i.e. whenever the value is
loaded from disk and consumed -- and keep the lower MIN_INLINE_XATTR_SIZE
bound gated on inodes that actually carry an inline xattr, so legitimate
inodes with i_inline_xattr_size == 0 are still accepted.

f2fs: validate ACL entry sizes in f2fs_acl_from_disk()
f2fs_acl_count() only validates the aggregate ACL xattr length. A
malformed ACL can still place ACL_USER or ACL_GROUP in a slot that only
contains struct f2fs_acl_entry_short bytes, and f2fs_acl_from_disk()
then reads entry->e_id before verifying that a full entry fits.
Require a short entry before reading e_tag and e_perm, and require a
full entry before reading e_id for ACL_USER and ACL_GROUP. Return
-EFSCORRUPTED from these new truncated-entry checks, while keeping the
pre-existing -EINVAL paths unchanged.

f2fs: reject setattr size changes on large folio files
F2FS large folios are only enabled for immutable non-compressed files.
Writable open and writable mmap reject such mappings, but truncate(2)
through f2fs_setattr() misses the same guard.
If FS_IMMUTABLE_FL is cleared while the inode is still cached, the mapping
can keep large-folio support and ATTR_SIZE can change i_size. Reject size
changes in that state.

f2fs: validate dentry name length before lookup compares it
The f2fs dentry lookup path can use the on-disk name length before checking that the name fits in the dentry filename area. A corrupted dentry can then make lookup read beyond the filename slots. The bounds check needs to happen before any comparison that consumes the name length from disk. Reject dentries with invalid name lengths before comparing their names.

f2fs: validate inline dentry name lengths before conversion
Inline dentry conversion copies names out of the inline dentry area before checking that each recorded name length fits in the available filename slots. A corrupted image can therefore make the conversion path read past the inline filename storage while building the regular dentry block. Validate each inline dentry name length against the inline filename area before copying it.

f2fs: read COW data with the original inode during atomic write
When updating an atomic-write file, f2fs_write_begin() may read the
previously written data back from the COW inode:
prepare_atomic_write_begin() locates the block in the COW inode and sets
use_cow, and the read bio is then built with the COW inode:
f2fs_submit_page_read(use_cow ? F2FS_I(inode)->cow_inode : inode,
...);
and f2fs_grab_read_bio() decides whether to schedule fs-layer decryption
(STEP_DECRYPT) for the bio based on that inode via
fscrypt_inode_uses_fs_layer_crypto().
However, the folio being filled belongs to the original inode
(folio->mapping->host == inode), and the data stored in the COW block was
encrypted (or left as plaintext) using the original inode's context, not
the COW inode's -- see f2fs_encrypt_one_page(), which keys off
fio->page->mapping->host. fscrypt_decrypt_pagecache_blocks() likewise
operates on folio->mapping->host.
The COW inode is created as a tmpfile in the parent directory and inherits
its encryption policy from there. With test_dummy_encryption the newly
created COW inode gets the dummy policy and becomes encrypted, while a
pre-existing regular file -- created before the policy applied, e.g.
already present in the on-disk image -- stays unencrypted. The read
path then sets STEP_DECRYPT based on the encrypted COW inode and calls
fscrypt_decrypt_pagecache_blocks() on a folio whose host (the unencrypted
original inode) has a NULL ->i_crypt_info, dereferencing it:
Oops: general protection fault, probably for non-canonical address ...

The COW inode is only needed to locate the on-disk block, and that block
address is already resolved into @blkaddr by prepare_atomic_write_begin()
via __find_data_block(cow_inode, ...); f2fs_submit_page_read() then reads
from that physical @blkaddr directly, so the inode argument only selects
the post-read crypto context, not which block is fetched. Reading with
@inode therefore returns the same (latest, not-yet-committed) COW data,
while making both the fs-layer decryption decision and the inline crypto
path use the correct (original inode's) key.
With the COW inode no longer used at the read site, the use_cow flag has no
remaining consumer; drop it from f2fs_write_begin() and
prepare_atomic_write_begin().

f2fs: skip inode folio lookup for cached overwrite
prepare_write_begin() first gets the inode folio and builds a dnode, then checks the read extent cache. For an ordinary overwrite of a non-inline and non-compressed file, an extent-cache hit already gives the data block address and the following path does not need to allocate or update any node state. Check the read extent cache before fetching the inode folio for that narrow case. Keep the existing paths for inline data, compressed files, and writes that may extend past EOF, where the helper may need inline conversion, compression preparation, or block reservation. This avoids a node-folio lookup in the buffered overwrite fast path when the mapping is already cached. In a QEMU/KASAN x86_64 VM, using a small buffered overwrite workload on an existing 1MiB file, median time improved as follows: 64-byte overwrites: 1724.93 ns/write -> 1560.24 ns/write 256-byte overwrites: 1713.38 ns/write -> 1577.85 ns/write Function profiling of 20k 64-byte overwrites showed f2fs_get_inode_folio() calls drop from 20004 to 4.

f2fs: keep atomic write retry from zeroing original data
A partial atomic write reserves a block in the COW inode before reading the
original data page for the untouched bytes in that page.
If that read fails, write_begin returns an error but leaves the COW inode
entry as NEW_ADDR. A retry of the same partial write then finds the COW
entry, treats it as existing COW data, and f2fs_write_begin() zeroes the
whole folio because blkaddr is NEW_ADDR.
If the retry is committed, the bytes outside the retried write range are
committed as zeroes instead of preserving the original file contents.
Only use the COW inode as the read source when it already has a real data
block. If the COW entry is still NEW_ADDR, treat it as a reservation to
reuse: keep reading the old data from the original inode and avoid
reserving or accounting the same atomic block again.

f2fs: validate orphan inode entry count
f2fs_recover_orphan_inodes() trusts the orphan block entry_count when
replaying orphan inodes from the checkpoint pack. A corrupted entry_count
larger than F2FS_ORPHANS_PER_BLOCK makes the recovery loop read past the
ino[] array and interpret footer or following data as inode numbers.
On a crafted image, mounting an unpatched kernel can drive orphan recovery
into f2fs_bug_on() and panic the kernel. Validate entry_count before
consuming entries so corrupted checkpoint data fails the mount with
-EFSCORRUPTED and requests fsck instead.
Set ERROR_INCONSISTENT_ORPHAN as well, so the corruption reason can be
recorded in the superblock s_errors[] field. This gives fsck a persistent
hint even though mount-time orphan recovery failure may leave no chance to
persist SBI_NEED_FSCK through a checkpoint.

f2fs: honor per-I/O write streams for direct writes
io_uring can pass a per-I/O write stream through kiocb->ki_write_stream,
and block direct I/O propagates that value to bio->bi_write_stream.
F2FS added FDP stream mapping for DATA writes, but its direct write
submit hook always rewrites bio->bi_write_stream from the inode write
hint and F2FS temperature. As a result, a direct write with an explicit
io_uring write_stream is submitted to the F2FS-selected stream instead
of the user-requested stream.
Validate an explicit write stream before starting F2FS direct I/O, pass
the kiocb through the iomap private pointer, and preserve the per-I/O
stream in the direct write bio. When no per-I/O stream is supplied, keep
using the existing F2FS temperature-to-stream mapping.
