Merge tag 'erofs-for-7.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs
Pull erofs updates from Gao Xiang:
"In this cycle, inode page cache sharing among filesystems on the same
machine is now supported, which is particularly useful for
high-density hosts running tens of thousands of containers.
In addition, we fully isolate the EROFS core on-disk format from other
optional encoded layouts since the core on-disk part is designed to be
simple, effective, and secure. Users can use the core format to build
unique golden immutable images and import their filesystem trees
directly from raw block devices via DMA, page-mapped DAX devices,
and/or file-backed mounts without having to worry about unnecessary
intrinsic consistency issues found in other generic filesystems by
design. However, the full vision is still working in progress and will
spend more time to achieve final goals.
There are other improvements and bug fixes as usual, as listed below:
- Support inode page cache sharing among filesystems
- Formally separate optional encoded (aka compressed) inode layouts
(and the implementations) from the EROFS core on-disk aligned plain
format for future zero-trust security usage
- Improve performance by caching the fact that an inode does not have

Pull hfs/hfsplus updates from Viacheslav Dubeyko:
"This pull request contains several fixes of syzbot reported issues and
HFS+ fixes of xfstests failures.
- fix an issue reported by syzbot triggering BUG_ON() in the case of
corrupted superblock, replacing the BUG_ON()s with proper error
handling (Jori Koolstra)
- fix memory leaks in the mount logic of HFS/HFS+ file systems. When
HFS/HFS+ were converted to the new mount api a bug was introduced
by changing the allocation pattern of sb->s_fs_info (Mehdi Ben Hadj
Khelifa)
- fix hfs_bnode_create() by returning ERR_PTR(-EEXIST) instead of
the node pointer when it's already hashed. This avoids a double
unload_nls() on mount failure (suggested by Shardul Bankar)
- set inode's mode as regular file for system inodes (Tetsuo Handa)
The rest fix failures in generic/020, generic/037, generic/062,
generic/480, and generic/498 xfstests for the case of HFS+ file
system. Currently, only 30 xfstests' test-cases experience failures
for HFS+ file system (initially, it was around 100 failed xfstests)"

Pull btrfs updates from David Sterba:
"User visible changes, feature updates:
- when using block size > page size, enable direct IO
- fallback to buffered IO if the data profile has duplication,
workaround to avoid checksum mismatches on block group profiles
with redundancy, real direct IO is possible on single or RAID0
- redo export of zoned statistics, moved from sysfs to
/proc/pid/mountstats due to size limitations of the former
Experimental features:
- remove offload checksum tunable, intended to find best way to do it
but since we've switched to offload to thread for everything we
don't need it anymore
- initial support for remap-tree feature, a translation layer of
logical block addresses that allow changes without moving/rewriting
blocks to do eg. relocation, or other changes that require COW
Notable fixes:
- automatic removal of accidentally leftover chunks when
free-space-tree is enabled since mkfs.btrfs v6.16.1
- zoned mode:
- do not try to append to conventional zones when RAID is mixing
zoned and conventional drives
- fixup write pointers when mixing zoned and conventional on
DUP/RAID* profiles
- when using squota, relax deletion rules for qgroups with 0 members
to allow easier recovery from accounting bugs, also add more checks
to detect bad accounting
- fix periodic reclaim scanning, properly check boundary conditions
not to trigger it unexpectedly or miss the time to run it
- trim:
- continue after first error
- change reporting to the first detected error
- add more cancellation points
- reduce contention of big device lock that can block other
operations when there's lots of trimmed space
- when chunk allocation is forced (needs experimental build) fix
transaction abort when unexpected space layout is detected
Core:
- switch to crypto library API for checksumming, removed module
dependencies, pointer indirections, etc.
- error handling improvements
- adjust how and where transaction commit or abort are done and are
maybe not necessary
- minor compression optimization to skip single block ranges
- improve how compression folios are handled
- new and updated selftests
- cleanups, refactoring:
- auto-freeing and other automatic variable cleanup conversion
- structure size optimizations
- condition annotations"

Pull misc vfs updates from Christian Brauner:
"This contains a mix of VFS cleanups, performance improvements, API
fixes, documentation, and a deprecation notice.
Scalability and performance:
- Rework pid allocation to only take pidmap_lock once instead of
twice during alloc_pid(), improving thread creation/teardown
throughput by 10-16% depending on false-sharing luck. Pad the
namespace refcount to reduce false-sharing
- Track file lock presence via a flag in ->i_opflags instead of
reading ->i_flctx, avoiding false-sharing with ->i_readcount on
open/close hot paths. Measured 4-16% improvement on 24-core
open-in-a-loop benchmarks
- Use a consume fence in locks_inode_context() to match the
store-release/load-consume idiom, eliminating a hardware fence on
some architectures
- Annotate cdev_lock with __cacheline_aligned_in_smp to prevent
false-sharing
- Remove a redundant DCACHE_MANAGED_DENTRY check in
__follow_mount_rcu() that never fires since the caller already
verifies it, eliminating a 100% mispredicted branch
- Fix a 100% mispredicted likely() in devcgroup_inode_permission()
that became wrong after a prior code reorder
Bug fixes and correctness:
- Make insert_inode_locked() wait for inode destruction instead of
skipping, fixing a corner case where two matching inodes could
exist in the hash
- Move f_mode initialization before file_ref_init() in alloc_file()
to respect the SLAB_TYPESAFE_BY_RCU ordering contract
- Add a WARN_ON_ONCE guard in try_to_free_buffers() for folios with
no buffers attached, preventing a null pointer dereference when
AS_RELEASE_ALWAYS is set but no release_folio op exists
- Fix select restart_block to store end_time as timespec64, avoiding
truncation of tv_sec on 32-bit architectures
- Make dump_inode() use get_kernel_nofault() to safely access inode
and superblock fields, matching the dump_mapping() pattern
API modernization:
- Make posix_acl_to_xattr() allocate the buffer internally since
every single caller was doing it anyway. Reduces boilerplate and
unnecessary error checking across ~15 filesystems
- Replace deprecated simple_strtoul() with kstrtoul() for the
ihash_entries, dhash_entries, mhash_entries, and mphash_entries
boot parameters, adding proper error handling
- Convert chardev code to use guard(mutex) and __free(kfree) cleanup
patterns
- Replace min_t() with min() or umin() in VFS code to avoid silently
truncating unsigned long to unsigned int
- Gate LOOKUP_RCU assertions behind CONFIG_DEBUG_VFS since callers
already check the flag
Deprecation:
- Begin deprecating legacy BSD process accounting (acct(2)). The
interface has numerous footguns and better alternatives exist
(eBPF)
Documentation:
- Fix and complete kernel-doc for struct export_operations, removing
duplicated documentation between ReST and source
- Fix kernel-doc warnings for __start_dirop() and ilookup5_nowait()
Testing:
- Add a kunit test for initramfs cpio handling of entries with
filesize > PATH_MAX
Misc:
- Add missing <linux/init_task.h> include in fs_struct.c"

When set, statmount() returns mount information for the mount the fd resides on — including detached mounts (unmounted via umount2(MNT_DETACH)). For detached mounts the STATMOUNT_MNT_POINT and STATMOUNT_MNT_NS_ID mask bits are cleared since neither is meaningful. The capability check is skipped for STATMOUNT_BY_FD since holding an fd already implies prior access to the mount and equivalent information is available through fstatfs() and /proc/pid/mountinfo without privilege. Includes comprehensive selftests covering both attached and detached mount cases. - fs: Remove internal old mount API code (1 patch) Now that every in-tree filesystem has been converted to the new mount API, remove all the legacy shim code in fs_context.c that handled unconverted filesystems. This deletes ~280 lines including legacy_init_fs_context(), the legacy_fs_context struct, and associated wrappers. The mount(2) syscall path for userspace remains untouched. Documentation references to the legacy callbacks are cleaned up. - mount: add OPEN_TREE_NAMESPACE to open_tree() Container runtimes currently use CLONE_NEWNS to copy the caller's entire mount namespace — only to then pivot_root() and recursively unmount everything they just copied. With large mount tables and thousands of parallel container launches this creates significant contention on the namespace semaphore. OPEN_TREE_NAMESPACE copies only the specified mount tree (like OPEN_TREE_CLONE) but returns a mount namespace fd instead of a detached mount fd. The new namespace contains the copied tree mounted on top of a clone of the real rootfs. This functions as a combined unshare(CLONE_NEWNS) + pivot_root() in a single syscall. Works with user namespaces: an unshare(CLONE_NEWUSER) followed by OPEN_TREE_NAMESPACE creates a mount namespace owned by the new user namespace. Mount namespace file mounts are excluded from the copy to prevent cycles.

Pull vfs nullfs update from Christian Brauner:
"Add a completely catatonic minimal pseudo filesystem called "nullfs"
and make pivot_root() work in the initramfs.
Currently pivot_root() does not work on the real rootfs because it
cannot be unmounted. Userspace has to recursively delete initramfs
contents manually before continuing boot, using the fragile
switch_root sequence (overmount + chroot).
Add nullfs, a minimal immutable filesystem that serves as the true
root of the mount hierarchy. The mutable rootfs (tmpfs/ramfs) is
mounted on top of it. This allows userspace to simply:
chdir(new_root);
pivot_root(".", ".");
umount2(".", MNT_DETACH);
without the traditional switch_root workarounds. systemd already
handles this correctly. It tries pivot_root() first and falls back
to MS_MOVE only when that fails.
This also means rootfs mounts in unprivileged namespaces no longer
need MNT_LOCKED, since the immutable nullfs guarantees nothing can be
revealed by unmounting the covering mount.
nullfs is a single-instance filesystem (get_tree_single()) marked
SB_NOUSER | SB_I_NOEXEC | SB_I_NODEV with an immutable empty root
directory. This means sooner or later it can be used to overmount
other directories to hide their contents without any additional
protection needed.
We enable it unconditionally. If we see any real regression we'll
hide it behind a boot option.
nullfs has extensions beyond this in the future. It will serve as a
concept to support the creation of completely empty mount namespaces -
which is work coming up in the next cycle"

This introduces a generic fserror infrastructure built around struct super_block that gives filesystems a standard way to queue metadata and file I/O error reports for delivery to fsnotify. Errors are queued via mempools and queue_work to avoid holding filesystem locks in the notification path; unmount waits for pending events to drain. A new super_operations::report_error callback lets filesystem drivers respond to file I/O errors themselves (to be used by an upcoming XFS self-healing patchset).

This new approach to structuring the NETFILTER_PKT record generation should eliminate some unnecessary overhead when audit is not built into the kernel. - Update the audit syscall classifier code Add the listxattrat(), getxattrat(), and fchmodat2() syscall to the audit code which classifies syscalls into categories of operations, e.g. "read" or "change attributes". - Move the syscall classifier declarations into audit_arch.h Shuffle around some header file declarations to resolve some sparse warnings. * tag 'audit-pr-20260203' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit: audit: move the compat_xxx_class[] extern declarations to audit_arch.h audit: add missing syscalls to read class audit: include source and destination ports to NETFILTER_PKT audit: add audit_log_nf_skb helper function audit: add fchmodat2() to change attributes class |

RCU changes for v7.0
RCU Tasks Trace:
Re-implement RCU tasks trace in term of SRCU-fast, not only more than 500 lines
of code are saved because of the reimplementation, a new set of API,
rcu_read_{,un}lock_tasks_trace(), becomes possible as well. Compared to the
previous rcu_read_{,un}lock_trace(), the new API avoid the task_struct accesses
thanks to the SRCU-fast semantics. As a result, the old
rcu_read{,un}lock_trace() API is now deprecated.
RCU Torture Test:
- Multiple improvements on kvm-series.sh (parallel run and progress showing
metrics)
- Add context checks to rcu_torture_timer().
- Make config2csv.sh properly handle comments in .boot files.
- Include commit discription in testid.txt.
Miscellaneous RCU changes:
- Reduce synchronize_rcu() latency by reporting GP kthread's CPU QS early.
- Use suitable gfp_flags for the init_srcu_struct_nodes().
- Fix rcu_read_unlock() deadloop due to softirq.
- Correctly compute probability to invoke ->exp_current() in rcutorture.
- Make expedited RCU CPU stall warnings detect stall-end races.
RCU nocb:
- Remove unnecessary WakeOvfIsDeferred wake path and callback overload
handling.
- Extract nocb_defer_wakeup_cancel() helper.

hfsplus: avoid double unload_nls() on mount failure
The recent commit "hfsplus: ensure sb->s_fs_info is always cleaned up" [1] introduced a custom ->kill_sb() handler (hfsplus_kill_super) that cleans up the s_fs_info structure (including the NLS table) on superblock destruction. However, the error handling path in hfsplus_fill_super() still calls unload_nls() before returning an error. Since the VFS layer calls ->kill_sb() when fill_super fails, this results in unload_nls() being called twice for the same sbi->nls pointer: once in hfsplus_fill_super() and again in hfsplus_kill_super() (via delayed_free). Remove the explicit unload_nls() call from the error path in hfsplus_fill_super() to rely solely on the cleanup in ->kill_sb().

x86/vmware: Fix hypercall clobbers
Fedora QA reported the following panic: BUG: unable to handle page fault for address: 0000000040003e54 #PF: supervisor write access in kernel mode #PF: error_code(0x0002) - not-present page Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS edk2-20251119-3.fc43 11/19/2025 RIP: 0010:vmware_hypercall4.constprop.0+0x52/0x90 .. Call Trace: vmmouse_report_events+0x13e/0x1b0 psmouse_handle_byte+0x15/0x60 ps2_interrupt+0x8a/0xd0 ... because the QEMU VMware mouse emulation is buggy, and clears the top 32 bits of %rdi that the kernel kept a pointer in. The QEMU vmmouse driver saves and restores the register state in a "uint32_t data[6];" and as a result restores the state with the high bits all cleared. RDI originally contained the value of a valid kernel stack address (0xff5eeb3240003e54). After the vmware hypercall it now contains 0x40003e54, and we get a page fault as a result when it is dereferenced. The proper fix would be in QEMU, but this works around the issue in the kernel to keep old setups working, when old kernels had not happened to keep any state in %rdi over the hypercall. In theory this same issue exists for all the hypercalls in the vmmouse driver; in practice it has only been seen with vmware_hypercall3() and vmware_hypercall4(). For now, just mark RDI/RSI as clobbered for those two calls. This should have a minimal effect on code generation overall as it should be rare for the compiler to want to make RDI/RSI live across hypercalls.

tracing fix for v6.19:
- Fix event format field alignments for 32 bit architectures The fields in the event format files are used to parse the raw binary buffer data by applications. If they are incorrect, then the application produces garbage. On 32 bit architectures, the function graph 64bit calltime and rettime were off by 4bytes. That's because the actual fields are in a packed structure but the macros used by the ftrace events did not mark them as packed, and instead, gave them their natural alignment which made their offsets off by 4 bytes. There are macros to have a packed field within an embedded structure of an event, but there's no macro for normal fields within a packed structure of the event. The macro __field_packed() was used for the packed embedded structure field. Rename that to __field_desc_pcaked() (to match the non-packed embedded field macro __field_desc()), and make __field_packed() for fields that are in a packed event structure (which matches the unpacked __field() macro). Switch the calltime and rettime fields of the function graph event to use the new __field_packed() and this makes the offsets correct. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCaYZKpRQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qk1UAP41H5PL24xmYp+34GIP6lHuJr6iZzUm KbZi1Zx4zNmXSAD/e3Ra5SZopWszeMTf/tmxUXbl30oLdw4CJgS1WztBggk= =m36h -----END PGP SIGNATURE----- Merge tag 'trace-v6.19-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fix from Steven Rostedt: - Fix event format field alignments for 32 bit architectures The fields in the event format files are used to parse the raw binary buffer data by applications.

iommu/vt-d: Treat PAGE_SNOOP and PWSNP separately
The PASID_FLAG_PAGE_SNOOP and PASID_FLAG_PWSNP constants are identical.
This will cause the pasid code to always set both or neither of the
PGSNP and PWSNP bits in PASID table entries. However, PWSNP is a
reserved bit if SMPWC is not set in the IOMMU's extended capability
register, even if SC is supported.
This has resulted in DMAR errors when testing the iommufd code on an
Arrow Lake platform. With this patch, those errors disappear and the
PASID table entries look correct.

When __memcg_slab_post_alloc_hook() fails, there are two different
free paths depending on whether size == 1 or size != 1. In the
kmem_cache_free_bulk() path, we do call alloc_tagging_slab_free_hook().
However, in memcg_alloc_abort_single() we don't, the above warning will be
triggered on the next allocation.
Therefore, add alloc_tagging_slab_free_hook() to the
memcg_alloc_abort_single() path.

EROFS may encounter above panic when enabling file-backed mount w/
directio mount option, the root cause is it may suffer UAF in below
race condition:
- z_erofs_read_folio wq s_dio_done_wq
- z_erofs_runqueue
- erofs_fileio_submit_bio
- erofs_fileio_rq_submit
- vfs_iocb_iter_read
- ext4_file_read_iter
- ext4_dio_read_iter
- iomap_dio_rw
: bio was submitted and return -EIOCBQUEUED
- dio_aio_complete_work
- dio_complete
- dio->iocb->ki_complete (erofs_fileio_ki_complete())
- kfree(rq)
: it frees iocb, iocb.ki_filp can be UAF in file_accessed().
- file_accessed
: access NULL file point
Introduce a reference count in struct erofs_fileio_rq, and initialize it
as two, both erofs_fileio_ki_complete() and erofs_fileio_rq_submit() will
decrease reference count, the last one decreasing the reference count
to zero will free rq.
