smb: client: let recv_done() avoid touching data_transfer after cleanup/move
Calling enqueue_reassembly() and wake_up_interruptible(&info->wait_reassembly_queue)
or put_receive_buffer() means the response/data_transfer pointer might
get re-used by another thread, which means these should be
the last operations before calling return.

smb: client: let recv_done() cleanup before notifying the callers.
We should call put_receive_buffer() before waking up the callers.
For the internal error case of response->type being unexpected,
we now also call smbd_disconnect_rdma_connection() instead
of not waking up the callers at all.
Note that the SMBD_TRANSFER_DATA case still has problems,
which will be addressed in the next commit in order to make
it easier to review this one.

The root cause is an initialization order problem. The lock is declared
as a global variable and intended to be initialized during module startup.
However, the procfs entry that uses this lock can be accessed by userspace
before the spin_lock_init() call has run. This creates a race window where
reading the proc file will attempt to use the lock before it is
initialized, leading to the crash.
For a global lock with a static lifetime, the correct and robust approach
is to use compile-time initialization.

btrfs: fix log tree replay failure due to file with 0 links and extents
If we log a new inode (not persisted in a past transaction) that has 0 links and extents, then log another inode with an higher inode number, we end up with failing to replay the log tree with -EINVAL. The steps for this are: 1) create new file A 2) write some data to file A 3) open an fd on file A 4) unlink file A 5) fsync file A using the previously open fd 6) create file B (has higher inode number than file A) 7) fsync file B 8) power fail before current transaction commits Now when attempting to mount the fs, the log replay will fail with -ENOENT at replay_one_extent() when attempting to replay the first extent of file A. The failure comes when trying to open the inode for file A in the subvolume tree, since it doesn't exist. Before commit |

smb: client: smb: client: eliminate mid_flags field
This is step 3/4 of a patch series to fix mid_q_entry memory leaks caused by race conditions in callback execution. Replace the mid_flags bitmask with dedicated boolean fields to simplify locking logic and improve code readability: - Replace MID_DELETED with bool deleted_from_q - Replace MID_WAIT_CANCELLED with bool wait_cancelled - Remove mid_flags field entirely The new boolean fields have clearer semantics: - deleted_from_q: whether mid has been removed from pending_mid_q - wait_cancelled: whether request was cancelled during wait This change reduces memory usage (from 4-byte bitmask to 2 boolean flags) and eliminates confusion about which lock protects which flag bits, preparing for per-mid locking in the next patch.

smb: client: add mid_counter_lock to protect the mid counter counter
This is step 2/4 of a patch series to fix mid_q_entry memory leaks caused by race conditions in callback execution. Add a dedicated mid_counter_lock to protect current_mid counter, separating it from mid_queue_lock which protects pending_mid_q operations. This reduces lock contention and prepares for finer- grained locking in subsequent patches. Changes: - Add TCP_Server_Info->mid_counter_lock spinlock - Rename CurrentMid to current_mid for consistency - Use mid_counter_lock to protect current_mid access - Update locking documentation in cifsglob.h This separation allows mid allocation to proceed without blocking queue operations, improving performance under heavy load.

smb: client: rename server mid_lock to mid_queue_lock
This is step 1/4 of a patch series to fix mid_q_entry memory leaks caused by race conditions in callback execution. The current mid_lock name is somewhat ambiguous about what it protects. To prepare for splitting this lock into separate, more granular locks, this patch renames mid_lock to mid_queue_lock to clearly indicate its specific responsibility for protecting the pending_mid_q list and related queue operations. No functional changes are made in this patch - it only prepares the codebase for the lock splitting that follows. - mid_queue_lock for queue operations - mid_counter_lock for mid counter operations - per-mid locks for individual mid state management Signed-off-by: Wang Zhaolong <wangzhaolong@huaweicloud.com> Acked-by: Enzo Matsumiya <ematsumiya@suse.de> Signed-off-by: Steve French <stfrench@microsoft.com> |

nfsd: avoid ref leak in nfsd_open_local_fh()
If two calls to nfsd_open_local_fh() race and both successfully call
nfsd_file_acquire_local(), they will both get an extra reference to the
net to accompany the file reference stored in *pnf.
One of them will fail to store (using xchg()) the file reference in
*pnf and will drop that reference but WON'T drop the accompanying
reference to the net. This leak means that when the nfs server is shut
down it will hang in nfsd_shutdown_net() waiting for
&nn->nfsd_net_free_done.
This patch adds the missing nfsd_net_put().

nfsd: don't set the ctime on delegated atime updates
Clients will typically precede a DELEGRETURN for a delegation with
delegated timestamp with a SETATTR to set the timestamps on the server
to match what the client has.
knfsd implements this by using the nfsd_setattr() infrastructure, which
will set ATTR_CTIME on any update that goes to notify_change(). This is
problematic as it means that the client will get a spurious ctime
update when updating the atime.
POSIX unfortunately doesn't phrase it succinctly, but updating the atime
due to reads should not update the ctime. In this case, the client is
sending a SETATTR to update the atime on the server to match its latest
value. The ctime should not be advanced in this case as that would
incorrectly indicate a change to the inode.
Fix this by not implicitly setting ATTR_CTIME when ATTR_DELEG is set in
__nfsd_setattr(). The decoder for FATTR4_WORD2_TIME_DELEG_MODIFY already
sets ATTR_CTIME, so this is sufficient to make it skip setting the ctime
on atime-only updates.

NFSv4: Remove duplicate lookups, capability probes and fsinfo calls
When crossing into a new filesystem, the NFSv4 client will look up the new directory, and then call nfs4_server_capabilities() as well as nfs4_do_fsinfo() at least twice.

The usage of read_seqbegin_or_lock() in nfs_copy_boot_verifier() is wrong.

- The cluster chain includes a loop.
- There is no UNUSED entry in the cluster chain.
(2) Condition for exfat_create_upcase_table() to loop infinitely.
- The cluster chain of the root directory includes a loop.
- There are no UNUSED entry and up-case table entry in the cluster
chain of the root directory.
(3) Condition for exfat_load_bitmap() to loop infinitely.
- The cluster chain of the root directory includes a loop.
- There are no UNUSED entry and bitmap entry in the cluster chain
of the root directory.
(4) Condition for exfat_find_dir_entry() to loop infinitely.
- The cluster chain includes a loop.
- The unused directory entries were exhausted by some operation.
(5) Condition for exfat_check_dir_empty() to loop infinitely.
- The cluster chain includes a loop.
- The unused directory entries were exhausted by some operation.
- All files and sub-directories under the directory are deleted.
This commit adds checks to break the above infinite loop.

exfat: fdatasync flag should be same like generic_write_sync()
Test: androbench by default setting, use 64GB sdcard.
the random write speed:
without this patch 3.5MB/s
with this patch 7MB/s
After patch "11a347fb6cef", the random write speed decreased significantly.
the .write_iter() interface had been modified, and check the differences
with generic_file_write_iter(), when calling generic_write_sync() and
exfat_file_write_iter() to call vfs_fsync_range(), the fdatasync flag is
wrong, and make not use the fdatasync mode, and make random write speed
decreased. So use generic_write_sync() instead of vfs_fsync_range().

creates a standalone notifier for NUMA node memory state changes.
Previously these were lumped under the more general memory on/offline
notifier.
- The 6 patch series "Make MIGRATE_ISOLATE a standalone bit" from Zi Yan
cleans up the pageblock isolation code and fixes a potential issue which
doesn't seem to cause any problems in practice.
- The 5 patch series "selftests/damon: add python and drgn based DAMON
sysfs functionality tests" from SeongJae Park adds additional drgn- and
python-based DAMON selftests which are more comprehensive than the
existing selftest suite.
- The 5 patch series "Misc rework on hugetlb faulting path" from Oscar
Salvador fixes a rather obscure deadlock in the hugetlb fault code and
follows that fix with a series of cleanups.
- The 3 patch series "cma: factor out allocation logic from
__cma_declare_contiguous_nid" from Mike Rapoport rationalizes and cleans
up the highmem-specific code in the CMA allocator.
- The 28 patch series "mm/migration: rework movable_ops page migration
(part 1)" from David Hildenbrand provides cleanups and
future-preparedness to the migration code.
- The 2 patch series "mm/damon: add trace events for auto-tuned
monitoring intervals and DAMOS quota" from SeongJae Park adds some
tracepoints to some DAMON auto-tuning code.
- The 6 patch series "mm/damon: fix misc bugs in DAMON modules" from
SeongJae Park does that.
- The 6 patch series "mm/damon: misc cleanups" from SeongJae Park also
does what it claims.
- The 4 patch series "mm: folio_pte_batch() improvements" from David
Hildenbrand cleans up the large folio PTE batching code.
- The 13 patch series "mm/damon/vaddr: Allow interleaving in
migrate_{hot,cold} actions" from SeongJae Park facilitates dynamic
alteration of DAMON's inter-node allocation policy.
- The 3 patch series "Remove unmap_and_put_page()" from Vishal Moola
provides a couple of page->folio conversions.
- The 4 patch series "mm: per-node proactive reclaim" from Davidlohr
Bueso implements a per-node control of proactive reclaim - beyond the
current memcg-based implementation.
- The 14 patch series "mm/damon: remove damon_callback" from SeongJae
Park replaces the damon_callback interface with a more general and
powerful damon_call()+damos_walk() interface.
- The 10 patch series "mm/mremap: permit mremap() move of multiple VMAs"
from Lorenzo Stoakes implements a number of mremap cleanups (of course)
in preparation for adding new mremap() functionality: newly permit the
remapping of multiple VMAs when the user is specifying MREMAP_FIXED. It
still excludes some specialized situations where this cannot be
performed reliably.
- The 3 patch series "drop hugetlb_free_pgd_range()" from Anthony Yznaga
switches some sparc hugetlb code over to the generic version and removes
the thus-unneeded hugetlb_free_pgd_range().
- The 4 patch series "mm/damon/sysfs: support periodic and automated
stats update" from SeongJae Park augments the present
userspace-requested update of DAMON sysfs monitoring files. Automatic
update is now provided, along with a tunable to control the update
interval.
- The 4 patch series "Some randome fixes and cleanups to swapfile" from
Kemeng Shi does what is claims.
- The 4 patch series "mm: introduce snapshot_page" from Luiz Capitulino
and David Hildenbrand provides (and uses) a means by which debug-style
functions can grab a copy of a pageframe and inspect it locklessly
without tripping over the races inherent in operating on the live
pageframe directly.
- The 6 patch series "use per-vma locks for /proc/pid/maps reads" from
Suren Baghdasaryan addresses the large contention issues which can be
triggered by reads from that procfs file. Latencies are reduced by more
than half in some situations. The series also introduces several new
selftests for the /proc/pid/maps interface.
- The 6 patch series "__folio_split() clean up" from Zi Yan cleans up
__folio_split()!
- The 7 patch series "Optimize mprotect() for large folios" from Dev
Jain provides some quite large (>3x) speedups to mprotect() when dealing
with large folios.
- The 2 patch series "selftests/mm: reuse FORCE_READ to replace "asm
volatile("" : "+r" (XXX));" and some cleanup" from wang lian does some
cleanup work in the selftests code.
- The 3 patch series "tools/testing: expand mremap testing" from Lorenzo
Stoakes extends the mremap() selftest in several ways, including adding
more checking of Lorenzo's recently added "permit mremap() move of
multiple VMAs" feature.
- The 22 patch series "selftests/damon/sysfs.py: test all parameters"
from SeongJae Park extends the DAMON sysfs interface selftest so that it
tests all possible user-requested parameters. Rather than the present
minimal subset.

Pull MM updates from Andrew Morton:
"As usual, many cleanups. The below blurbiage describes 42 patchsets.
21 of those are partially or fully cleanup work. "cleans up",
"cleanup", "maintainability", "rationalizes", etc.
I never knew the MM code was so dirty.
"mm: ksm: prevent KSM from breaking merging of new VMAs" (Lorenzo Stoakes)

mapped VMAs were not eligible for merging with existing adjacent
VMAs.
"mm/damon: introduce DAMON_STAT for simple and practical access monitoring" (SeongJae Park)
adds a new kernel module which simplifies the setup and usage of
DAMON in production environments.
"stop passing a writeback_control to swap/shmem writeout" (Christoph Hellwig)
is a cleanup to the writeback code which removes a couple of
pointers from struct writeback_control.
"drivers/base/node.c: optimization and cleanups" (Donet Tom)
contains largely uncorrelated cleanups to the NUMA node setup and
management code.
"mm: userfaultfd: assorted fixes and cleanups" (Tal Zussman)

implements some tuneups for pagecache readahead when it is reading
into order>0 folios.
"selftests/mm: Tweaks to the cow test" (Mark Brown)
provides some cleanups and consistency improvements to the
selftests code.
"Optimize mremap() for large folios" (Dev Jain)
does that. A 37% reduction in execution time was measured in a
memset+mremap+munmap microbenchmark.
"Remove zero_user()" (Matthew Wilcox)
expunges zero_user() in favor of the more modern memzero_page().
"mm/huge_memory: vmf_insert_folio_*() and vmf_insert_pfn_pud() fixes" (David Hildenbrand)
addresses some warts which David noticed in the huge page code.
These were not known to be causing any issues at this time.
"mm/damon: use alloc_migrate_target() for DAMOS_MIGRATE_{HOT,COLD" (SeongJae Park)
provides some cleanup and consolidation work in DAMON.
"use vm_flags_t consistently" (Lorenzo Stoakes)
uses vm_flags_t in places where we were inappropriately using other
types.
"mm/memfd: Reserve hugetlb folios before allocation" (Vivek Kasireddy)
increases the reliability of large page allocation in the memfd
code.
"mm: Remove pXX_devmap page table bit and pfn_t type" (Alistair Popple)
removes several now-unneeded PFN_* flags.
"mm/damon: decouple sysfs from core" (SeongJae Park)
implememnts some cleanup and maintainability work in the DAMON
sysfs layer.
"madvise cleanup" (Lorenzo Stoakes)
does quite a lot of cleanup/maintenance work in the madvise() code.
"madvise anon_name cleanups" (Vlastimil Babka)
provides additional cleanups on top or Lorenzo's effort.

smb3 client: add way to show directory leases for improved debugging
When looking at performance issues around directory caching, or debugging directory lease issues, it is helpful to be able to display the current directory leases (as we can e.g. or open files). Create pseudo-file /proc/fs/cifs/open_dirs that displays current directory leases. Here is sample output: cat /proc/fs/cifs/open_dirs Version:1 Format: <tree id> <sess id> <persistent fid> <path> Num entries: 3 0xce4c1c68 0x7176aa54 0xd95ef58e \dira valid file info, valid dirents 0xce4c1c68 0x7176aa54 0xd031e211 \dir5 valid file info, valid dirents 0xce4c1c68 0x7176aa54 0x96533a90 \dir1 valid file info Reviewed-by: Bharath SM <bharathsm@microsoft.com> Signed-off-by: Steve French <stfrench@microsoft.com> |

Networking changes for 6.17.
Core & protocols
----------------
- Wrap datapath globals into net_aligned_data, to avoid false sharing.
- Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container).
- Add SO_INQ and SCM_INQ support to AF_UNIX.
- Add SIOCINQ support to AF_VSOCK.
- Add TCP_MAXSEG sockopt to MPTCP.
- Add IPv6 force_forwarding sysctl to enable forwarding per interface.
- Make TCP validation of whether packet fully fits in the receive
window and the rcv_buf more strict. With increased use of HW
aggregation a single "packet" can be multiple 100s of kB.
- Add MSG_MORE flag to optimize large TCP transmissions via sockmap,
improves latency up to 33% for sockmap users.
- Convert TCP send queue handling from tasklet to BH workque.
- Improve BPF iteration over TCP sockets to see each socket exactly once.
- Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code.
- Support enabling kernel threads for NAPI processing on per-NAPI
instance basis rather than a whole device. Fully stop the kernel NAPI
thread when threaded NAPI gets disabled. Previously thread would stick
around until ifdown due to tricky synchronization.
- Allow multicast routing to take effect on locally-generated packets.
- Add output interface argument for End.X in segment routing.
- MCTP: add support for gateway routing, improve bind() handling.
- Don't require rtnl_lock when fetching an IPv6 neighbor over Netlink.
- Add a new neighbor flag ("extern_valid"), which cedes refresh
responsibilities to userspace. This is needed for EVPN multi-homing
where a neighbor entry for a multi-homed host needs to be synced
across all the VTEPs among which the host is multi-homed.
- Support NUD_PERMANENT for proxy neighbor entries.
- Add a new queuing discipline for IETF RFC9332 DualQ Coupled AQM.
- Add sequence numbers to netconsole messages. Unregister netconsole's
console when all net targets are removed. Code refactoring.
Add a number of selftests.
- Align IPSec inbound SA lookup to RFC 4301. Only SPI and protocol
should be used for an inbound SA lookup.
- Support inspecting ref_tracker state via DebugFS.
- Don't force bonding advertisement frames tx to ~333 ms boundaries.
Add broadcast_neighbor option to send ARP/ND on all bonded links.
- Allow providing upcall pid for the 'execute' command in openvswitch.
- Remove DCCP support from Netfilter's conntrack.
- Disallow multiple packet duplications in the queuing layer.
- Prevent use of deprecated iptables code on PREEMPT_RT.
Driver API
----------
- Support RSS and hashing configuration over ethtool Netlink.
- Add dedicated ethtool callbacks for getting and setting hashing fields.
- Add support for power budget evaluation strategy in PSE /
Power-over-Ethernet. Generate Netlink events for overcurrent etc.
- Support DPLL phase offset monitoring across all device inputs.
Support providing clock reference and SYNC over separate DPLL
inputs.
- Support traffic classes in devlink rate API for bandwidth management.
- Remove rtnl_lock dependency from UDP tunnel port configuration.
Device drivers
--------------
- Add a new Broadcom driver for 800G Ethernet (bnge).
- Add a standalone driver for Microchip ZL3073x DPLL.

jfs: fix metapage reference count leak in dbAllocCtl
In dbAllocCtl(), read_metapage() increases the reference count of the
metapage. However, when dp->tree.budmin < 0, the function returns -EIO
without calling release_metapage() to decrease the reference count,
leading to a memory leak.
Add release_metapage(mp) before the error return to properly manage
the metapage reference count and prevent the leak.

fscrypt updates for 6.17
Simplify how fscrypt uses the crypto API, resulting in some
significant performance improvements:
- Drop the incomplete and problematic support for asynchronous
algorithms. These drivers are bug-prone, and it turns out they are
actually much slower than the CPU-based code as well.
- Allocate crypto requests on the stack instead of the heap. This
improves encryption and decryption performance, especially for
filenames. It also eliminates a point of failure during I/O.

CRC updates for 6.17
Updates for the kernel's CRC (cyclic redundancy check) code:
- Reorganize the architecture-optimized CRC code. It now lives in
lib/crc/$(SRCARCH)/ rather than arch/$(SRCARCH)/lib/, and it is no
longer artificially split into separate generic and arch modules.
This allows better inlining and dead code elimination. The generic
CRC code is also no longer exported, simplifying the API. (This
mirrors the similar changes to SHA-1 and SHA-2 in lib/crypto/,
which can be found in the "Crypto library updates" pull request.)
- Improve crc32c() performance on newer x86_64 CPUs on long messages
by enabling the VPCLMULQDQ optimized code.
- Simplify the crypto_shash wrappers for crc32_le() and crc32c().
Register just one shash algorithm for each that uses the (fully
optimized) library functions, instead of unnecessarily providing
direct access to the generic CRC code.
- Remove unused and obsolete drivers for hardware CRC engines.
- Remove CRC-32 combination functions that are no longer used.
- Add kerneldoc for crc32_le(), crc32_be(), and crc32c().
- Convert the crc32() macro to an inline function.

This is how these buffers were handled prior to having cloning support, and we can still use that approach as long as the buffers haven't been cloned to another ring. - Cleanup and improvement for uring_cmd, where btrfs was the only user of storing allocated data for the lifetime of the uring_cmd. Clean that up so we can get rid of the need to do that. - Avoid unnecessary memory copies in uring_cmd usage. This is particularly important as a lot of uring_cmd usage necessitates the use of 128b SQEs. - A few updates for recv multishot, where it's now possible to add fairness limits for limiting how much is transferred for each retry loop. Additionally, recv multishot now supports an overall cap as well, where once reached the multishot recv will terminate. The latter is useful for buffer management and juggling many recv streams at the same time. - Add support for returning the TX timestamps via a new socket command. This feature can work in either singleshot or multishot mode, where the latter triggers a completion whenever new timestamps are available. This is an alternative to using the existing error queue. - Add support for an io_uring "mock" file, which is the start of being able to do 100% targeted testing in terms of exercising io_uring request handling. The idea is to have a file type that can be anything the tester would like, and behave exactly how you want it to behave in terms of hitting the code paths you want. - Improve zcrx by using sgtables to de-duplicate and improve dma address handling. - Prep work for supporting larger pages for zcrx. - Various little improvements and fixes. * tag 'for-6.17/io_uring-20250728' of git://git.kernel.dk/linux: (42 commits) io_uring/zcrx: fix leaking pages on sg init fail io_uring/zcrx: don't leak pages on account failure io_uring/zcrx: fix null ifq on area destruction io_uring: fix breakage in EXPERT menu io_uring/cmd: remove struct io_uring_cmd_data btrfs/ioctl: store btrfs_uring_encoded_data in io_btrfs_cmd io_uring/cmd: introduce IORING_URING_CMD_REISSUE flag io_uring/zcrx: account area memory io_uring: export io_[un]account_mem io_uring/net: Support multishot receive len cap io_uring: deduplicate wakeup handling io_uring/net: cast min_not_zero() type io_uring/poll: cleanup apoll freeing io_uring/net: allow multishot receive per-invocation cap io_uring/net: move io_sr_msg->retry_flags to io_sr_msg->flags io_uring/net: use passed in 'len' in io_recv_buf_select() io_uring/zcrx: prepare fallback for larger pages io_uring/zcrx: assert area type in io_zcrx_iov_page io_uring/zcrx: allocate sgtable for umem areas io_uring/zcrx: introduce io_populate_area_dma ... |

fuse: remove page alignment check for writeback len
Remove incorrect page alignment check for the writeback len arg in
fuse_iomap_writeback_range(). len will always be block-aligned as
passed in by iomap.
On regular fuse filesystems, i_blkbits is set to PAGE_SHIFT so this is
not a problem but for fuseblk filesystems, the block size is set to a
default of 512 bytes or a block size passed in at mount time.
Please note that non-page-aligned lengths are fine for the logic in
fuse_iomap_writeback_range(). The check was originally added as a
safeguard to detect conspicuously wrong ranges.

Pull superblock callback update from Christian Brauner:
"Currently all filesystems which implement super_operations::shutdown()
can not afford losing a device.
Thus fs_bdev_mark_dead() will just call the ->shutdown() callback for
the involved filesystem.
But it will no longer be the case, as multi-device filesystems like
btrfs can handle certain device loss without the need to shutdown the
whole filesystem.
To allow those multi-device filesystems to be integrated to use
fs_holder_ops:
- Add a new super_operations::remove_bdev() callback
- Try ->remove_bdev() callback first inside fs_bdev_mark_dead().
If the callback returned 0, meaning the fs can handling the device
loss, then exit without doing anything else.
If there is no such callback or the callback returned non-zero
value, continue to shutdown the filesystem as usual.
This means the new remove_bdev() should only do the check on whether
the operation can continue, and if so do the fs specific handlings.
The shutdown handling should still be handled by the existing
->shutdown() callback.
For all existing filesystems with shutdown callback, there is no
change to the code nor behavior.
Btrfs is going to implement both the ->remove_bdev() and ->shutdown()
callbacks soon"

Both system calls serve as successors and extensible companions to the FS_IOC_FSGETXATTR and FS_IOC_FSSETXATTR system calls which have started to show their age in addition to being named in a way that makes it easy to conflate them with extended attribute related operations. These syscalls allow userspace to set filesystem inode attributes on special files. One of the usage examples is the XFS quota projects. XFS has project quotas which could be attached to a directory. All new inodes in these directories inherit project ID set on parent directory. The project is created from userspace by opening and calling FS_IOC_FSSETXATTR on each inode. This is not possible for special files such as FIFO, SOCK, BLK etc. Therefore, some inodes are left with empty project ID. Those inodes then are not shown in the quota accounting but still exist in the directory. This is not critical but in the case when special files are created in the directory with already existing project quota, these new inodes inherit extended attributes. This creates a mix of special files with and without attributes. Moreover, special files with attributes don't have a possibility to become clear or change the attributes. This, in turn, prevents userspace from re-creating quota project on these existing files.

Pull pidfs updates from Christian Brauner:
- persistent info
Persist exit and coredump information independent of whether anyone
currently holds a pidfd for the struct pid.
The current scheme allocated pidfs dentries on-demand repeatedly.
This scheme is reaching it's limits as it makes it impossible to pin
information that needs to be available after the task has exited or
coredumped and that should not be lost simply because the pidfd got
closed temporarily. The next opener should still see the stashed
information.
This is also a prerequisite for supporting extended attributes on
pidfds to allow attaching meta information to them.
If someone opens a pidfd for a struct pid a pidfs dentry is allocated
and stashed in pid->stashed. Once the last pidfd for the struct pid
is closed the pidfs dentry is released and removed from pid->stashed.
So if 10 callers create a pidfs dentry for the same struct pid
sequentially, i.e., each closing the pidfd before the other creates a
new one then a new pidfs dentry is allocated every time.
Because multiple tasks acquiring and releasing a pidfd for the same
struct pid can race with each another a task may still find a valid
pidfs entry from the previous task in pid->stashed and reuse it. Or
it might find a dead dentry in there and fail to reuse it and so
stashes a new pidfs dentry. Multiple tasks may race to stash a new
pidfs dentry but only one will succeed, the other ones will put their
dentry.
The current scheme aims to ensure that a pidfs dentry for a struct
pid can only be created if the task is still alive or if a pidfs
dentry already existed before the task was reaped and so exit
information has been was stashed in the pidfs inode.
That's great except that it's buggy. If a pidfs dentry is stashed in
pid->stashed after pidfs_exit() but before __unhash_process() is
called we will return a pidfd for a reaped task without exit
information being available.
The pidfds_pid_valid() check does not guard against this race as it
doens't sync at all with pidfs_exit(). The pid_has_task() check might
be successful simply because we're before __unhash_process() but
after pidfs_exit().
Introduce a new scheme where the lifetime of information associated
with a pidfs entry (coredump and exit information) isn't bound to the
lifetime of the pidfs inode but the struct pid itself.
The first time a pidfs dentry is allocated for a struct pid a struct
pidfs_attr will be allocated which will be used to store exit and
coredump information.
If all pidfs for the pidfs dentry are closed the dentry and inode can
be cleaned up but the struct pidfs_attr will stick until the struct
pid itself is freed. This will ensure minimal memory usage while
persisting relevant information.
The new scheme has various advantages. First, it allows to close the
race where we end up handing out a pidfd for a reaped task for which
no exit information is available. Second, it minimizes memory usage.
Third, it allows to remove complex lifetime tracking via dentries
when registering a struct pid with pidfs. There's no need to get or
put a reference. Instead, the lifetime of exit and coredump
information associated with a struct pid is bound to the lifetime of
struct pid itself.
- extended attributes
Now that we have a way to persist information for pidfs dentries we
can start supporting extended attributes on pidfds. This will allow
userspace to attach meta information to tasks.
One natural extension would be to introduce a custom pidfs.* extended
attribute space and allow for the inheritance of extended attributes
across fork() and exec().
The first simple scheme will allow privileged userspace to set
trusted extended attributes on pidfs inodes.
- Allow autonomous pidfs file handles
Various filesystems such as pidfs and drm support opening file
handles without having to require a file descriptor to identify the
filesystem. The filesystem are global single instances and can be
trivially identified solely on the information encoded in the file
handle.
This makes it possible to not have to keep or acquire a sentinal file
descriptor just to pass it to open_by_handle_at() to identify the
filesystem. That's especially useful when such sentinel file
descriptor cannot or should not be acquired.
For pidfs this means a file handle can function as full replacement
for storing a pid in a file. Instead a file handle can be stored and
reopened purely based on the file handle.
Such autonomous file handles can be opened with or without specifying
a a file descriptor. If no proper file descriptor is used the
FD_PIDFS_ROOT sentinel must be passed. This allows us to define
further special negative fd sentinels in the future.
Userspace can trivially test for support by trying to open the file
handle with an invalid file descriptor.
- Allow pidfds for reaped tasks with SCM_PIDFD messages
This is a logical continuation of the earlier work to create pidfds
for reaped tasks through the SO_PEERPIDFD socket option merged in

Pull fallocate updates from Christian Brauner:
"fallocate() currently supports creating preallocated files
efficiently. However, on most filesystems fallocate() will preallocate
blocks in an unwriten state even if FALLOC_FL_ZERO_RANGE is specified.
The extent state must later be converted to a written state when the
user writes data into this range, which can trigger numerous metadata
changes and journal I/O. This may leads to significant write
amplification and performance degradation in synchronous write mode.
At the moment, the only method to avoid this is to create an empty
file and write zero data into it (for example, using 'dd' with a large
block size). However, this method is slow and consumes a considerable
amount of disk bandwidth.
Now that more and more flash-based storage devices are available it is
possible to efficiently write zeros to SSDs using the unmap write
zeroes command if the devices do not write physical zeroes to the
media.
For example, if SCSI SSDs support the UMMAP bit or NVMe SSDs support
the DEAC bit[1], the write zeroes command does not write actual data
to the device, instead, NVMe converts the zeroed range to a
deallocated state, which works fast and consumes almost no disk write
bandwidth.
This series implements the BLK_FEAT_WRITE_ZEROES_UNMAP feature and
BLK_FLAG_WRITE_ZEROES_UNMAP_DISABLED flag for SCSI, NVMe and
device-mapper drivers, and add the FALLOC_FL_WRITE_ZEROES and
STATX_ATTR_WRITE_ZEROES_UNMAP support for ext4 and raw bdev devices.
fallocate() is subsequently extended with the FALLOC_FL_WRITE_ZEROES
flag. FALLOC_FL_WRITE_ZEROES zeroes a specified file range in such a
way that subsequent writes to that range do not require further
changes to the file mapping metadata. This flag is beneficial for
subsequent pure overwriting within this range, as it can save on block
allocation and, consequently, significant metadata changes"

Pull namespace updates from Christian Brauner:
"This contains namespace updates. This time specifically for nsfs:
- Userspace heavily relies on the root inode numbers for namespaces
to identify the initial namespaces. That's already a hard
dependency. So we cannot change that anymore. Move the initial
inode numbers to a public header and align the only two namespaces
that currently don't do that with all the other namespaces.
- The root inode of /proc having a fixed inode number has been part
of the core kernel ABI since its inception, and recently some
userspace programs (mainly container runtimes) have started to
explicitly depend on this behaviour.
The main reason this is useful to userspace is that by checking
that a suspect /proc handle has fstype PROC_SUPER_MAGIC and is
PROCFS_ROOT_INO, they can then use openat2() together with
RESOLVE_{NO_{XDEV,MAGICLINK},BENEATH} to ensure that there isn't a
bind-mount that replaces some procfs file with a different one.
This kind of attack has lead to security issues in container
runtimes in the past (such as CVE-2019-19921) and libraries like
libpathrs[1] use this feature of procfs to provide safe procfs

Pull coredump updates from Christian Brauner:
"This contains an extension to the coredump socket and a proper rework
of the coredump code.
- This extends the coredump socket to allow the coredump server to
tell the kernel how to process individual coredumps. This allows
for fine-grained coredump management. Userspace can decide to just
let the kernel write out the coredump, or generate the coredump
itself, or just reject it.
* COREDUMP_KERNEL
The kernel will write the coredump data to the socket.
* COREDUMP_USERSPACE
The kernel will not write coredump data but will indicate to the
parent that a coredump has been generated. This is used when
userspace generates its own coredumps.
* COREDUMP_REJECT
The kernel will skip generating a coredump for this task.
* COREDUMP_WAIT
The kernel will prevent the task from exiting until the coredump
server has shutdown the socket connection.
The flexible coredump socket can be enabled by using the "@@"
prefix instead of the single "@" prefix for the regular coredump
socket:
@@/run/systemd/coredump.socket
- Cleanup the coredump code properly while we have to touch it
anyway.
Split out each coredump mode in a separate helper so it's easy to
grasp what is going on and make the code easier to follow. The core
coredump function should now be very trivial to follow"

Pull misc VFS updates from Christian Brauner:
"This contains the usual selections of misc updates for this cycle.
Features:
- Add ext4 IOCB_DONTCACHE support
This refactors the address_space_operations write_begin() and
write_end() callbacks to take const struct kiocb * as their first
argument, allowing IOCB flags such as IOCB_DONTCACHE to propagate
to the filesystem's buffered I/O path.
Ext4 is updated to implement handling of the IOCB_DONTCACHE flag
and advertises support via the FOP_DONTCACHE file operation flag.
Additionally, the i915 driver's shmem write paths are updated to
bypass the legacy write_begin/write_end interface in favor of
directly calling write_iter() with a constructed synchronous kiocb.
Another i915 change replaces a manual write loop with
kernel_write() during GEM shmem object creation.
Cleanups:
- don't duplicate vfs_open() in kernel_file_open()
- proc_fd_getattr(): don't bother with S_ISDIR() check
- fs/ecryptfs: replace snprintf with sysfs_emit in show function
- vfs: Remove unnecessary list_for_each_entry_safe() from
evict_inodes()
- filelock: add new locks_wake_up_waiter() helper
- fs: Remove three arguments from block_write_end()
- VFS: change old_dir and new_dir in struct renamedata to dentrys
- netfs: Remove unused declaration netfs_queue_write_request()
Fixes:
- eventpoll: Fix semi-unbounded recursion
- eventpoll: fix sphinx documentation build warning
- fs/read_write: Fix spelling typo
- fs: annotate data race between poll_schedule_timeout() and
pollwake()
- fs/pipe: set FMODE_NOWAIT in create_pipe_files()
- docs/vfs: update references to i_mutex to i_rwsem
- fs/buffer: remove comment about hard sectorsize

mount changes. I've got more stuff in the local tree, but
this is getting too much for one merge window as it is.
* mount hash conflicts rudiments are gone now - we do not allow
multiple mounts with the same parent/mountpoint to be
hashed at the same time.
* struct mount changes
mnt_umounting is gone;
mnt_slave_list/mnt_slave is an hlist now;
overmounts are kept track of by explicit pointer in mount;
a bunch of flags moved out of mnt_flags to a new field,
with only namespace_sem for protection;
mnt_expiry is protected by mount_lock now (instead of
namespace_sem);
MNT_LOCKED is used only for mounts that need to remain
attached to their parents to prevent mountpoint exposure -
no more overloading it for absolute roots;
all mnt_list uses are transient now - it's used only to
represent temporary sets during umount_tree().
* mount refcounting change
children no longer pin parents for any mounts, whether they'd
passed through umount_tree() or not.
* struct mountpoint changes
refcount is no more; what matters is ->m_list emptiness;
instead of temporary bumping the refcount, we insert a new object
(pinned_mountpoint) into ->m_list;
new calling conventions for lock_mount() and friends.
* do_move_mount()/attach_recursive_mnt() seriously cleaned up.
* globals in fs/pnode.c are gone.
* propagate_mnt(), change_mnt_propagation() and propagate_umount() cleaned up
(in the last case - pretty much completely rewritten).
* freeing of emptied mnt_namespace is done in namespace_unlock()
for one thing, there are subtle ordering requirements there;
for another it simplifies cleanups.
* assorted cleanups.
* restore the machinery for long-term mounts from accumulated bitrot.
This is going to get a followup come next cycle, when #work.fs_context
with its change of vfs_fs_parse_string() calling conventions goes
into -next.

RIP: 0010:new_curseg+0x70f/0x720
The root cause of we run out-of-space is: in f2fs_map_blocks(), f2fs may
trigger foreground gc only if it allocates any physical block, it will be
a little bit later when there is multiple threads writing data w/
aio/dio/bufio method in parallel, since we always use OPU in lfs mode, so
f2fs_map_blocks() does block allocations aggressively.
In order to fix this issue, let's give a chance to trigger foreground
gc in prior to block allocation in f2fs_map_blocks().

Current exclusion rules for ->d_flags stores are rather unpleasant.
The basic rules are simple: * stores to dentry->d_flags are OK under dentry->d_lock. * stores to dentry->d_flags are OK in the dentry constructor, before becomes potentially visible to other threads. Unfortunately, there's a couple of exceptions to that, and that's where the headache comes from. Main PITA comes from d_set_d_op(); that primitive sets ->d_op of dentry and adjusts the flags that correspond to presence of individual methods. It's very easy to misuse; existing uses _are_ safe, but proof of correctness is brittle. Use in __d_alloc() is safe (we are within a constructor), but we might as well precalculate the initial value of ->d_flags when we set the default ->d_op for given superblock and set ->d_flags directly instead of messing with that helper. The reasons why other uses are safe are bloody convoluted; I'm not going to reproduce it here. See https://lore.kernel.org/all/20250224010624.GT1977892@ZenIV/ for gory details, if you care. The critical part is using d_set_d_op() only just prior to d_splice_alias(), which makes a combination of d_splice_alias() with setting ->d_op, etc. a natural replacement primitive. Better yet, if we go that way, it's easy to take setting ->d_op and modifying ->d_flags under ->d_lock, which eliminates the headache as far as ->d_flags exclusion rules are concerned. Other exceptions are minor and easy to deal with. What this series does: * d_set_d_op() is no longer available; new primitive (d_splice_alias_ops()) is provided, equivalent to combination of d_set_d_op() and d_splice_alias(). * new field of struct super_block - ->s_d_flags. Default value of ->d_flags to be used when allocating dentries on this filesystem. * new primitive for setting ->s_d_op: set_default_d_op(). Replaces stores to ->s_d_op at mount time. All in-tree filesystems converted; out-of-tree ones will get caught by compiler (->s_d_op is renamed, so stores to it will be caught). ->s_d_flags is set by the same primitive to match the ->s_d_op. * a lot of filesystems had ->s_d_op->d_delete equal to always_delete_dentry; that is equivalent to setting DCACHE_DONTCACHE in ->d_flags, so such filesystems can bloody well set that bit in ->s_d_flags and drop ->d_delete() from dentry_operations. In quite a few cases that results in empty dentry_operations, which means that we can get rid of those. * kill simple_dentry_operations - not needed anymore. * massage d_alloc_parallel() to get rid of the other exception wrt ->d_flags stores - we can set DCACHE_PAR_LOOKUP as soon as we allocate the new dentry; no need to delay that until we commit to using the sucker. As the result, ->d_flags stores are all either under ->d_lock or done before the dentry becomes visible in any shared data structures. -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQQqUNBr3gm4hGXdBJlZ7Krx/gZQ6wUCaIQ/tQAKCRBZ7Krx/gZQ 66AhAQDgQ+S224x5YevNXc9mDoGUBMF4OG0n0fIla9rfdL4I6wEAqpOWMNDcVPCZ GwYOvJ9YuqNdz+MyprAI18Yza4GOmgs= =rTYB -----END PGP SIGNATURE----- Merge tag 'pull-dcache' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs Pull dentry d_flags updates from Al Viro: "The current exclusion rules for dentry->d_flags stores are rather unpleasant.

This replaces stores to 's_d_op' at mount time. All in-tree filesystems converted; out-of-tree ones will get caught by the compiler ('s_d_op' is renamed, so stores to it will be caught). 's_d_flags' is set by the same primitive to match the 's_d_op'. - a lot of filesystems had sb->s_d_op->d_delete equal to always_delete_dentry; that is equivalent to setting DCACHE_DONTCACHE in 'd_flags', so such filesystems can bloody well set that bit in 's_d_flags' and drop 'd_delete()' from dentry_operations. In quite a few cases that results in empty dentry_operations, which means that we can get rid of those. - kill simple_dentry_operations - not needed anymore - massage d_alloc_parallel() to get rid of the other exception wrt 'd_flags' stores - we can set DCACHE_PAR_LOOKUP as soon as we allocate the new dentry; no need to delay that until we commit to using the sucker. As the result, 'd_flags' stores are all either under ->d_lock or done before the dentry becomes visible in any shared data structures" Link: https://lore.kernel.org/all/20250224010624.GT1977892@ZenIV/ [1] * tag 'pull-dcache' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (21 commits) configfs: use DCACHE_DONTCACHE debugfs: use DCACHE_DONTCACHE efivarfs: use DCACHE_DONTCACHE instead of always_delete_dentry() 9p: don't bother with always_delete_dentry ramfs, hugetlbfs, mqueue: set DCACHE_DONTCACHE kill simple_dentry_operations devpts, sunrpc, hostfs: don't bother with ->d_op shmem: no dentry retention past the refcount reaching zero d_alloc_parallel(): set DCACHE_PAR_LOOKUP earlier make d_set_d_op() static simple_lookup(): just set DCACHE_DONTCACHE tracefs: Add d_delete to remove negative dentries set_default_d_op(): calculate the matching value for ->d_flags correct the set of flags forbidden at d_set_d_op() time split d_flags calculation out of d_set_d_op() new helper: set_default_d_op() fuse: no need for special dentry_operations for root dentry switch procfs from d_set_d_op() to d_splice_alias_ops() new helper: d_splice_alias_ops() procfs: kill ->proc_dops ... |

fsnotify: optimize FMODE_NONOTIFY_PERM for the common cases
The most unlikely watched permission event is FAN_ACCESS_PERM, because at the time that it was introduced there were no evictable ignore mark, so subscribing to FAN_ACCESS_PERM would have incured a very high overhead. Yet, when we set the fmode to FMODE_NOTIFY_HSM(), we never skip trying to send FAN_ACCESS_PERM, which is almost always a waste of cycles. We got to this logic because of bundling FAN_OPEN*_PERM and FAN_ACCESS_PERM in the same category and because FAN_OPEN_PERM is a commonly used event. By open coding fsnotify_open_perm() in fsnotify_open_perm_and_set_mode(), we no longer need to regard FAN_OPEN*_PERM when calculating fmode. This leaves the case of having pre-content events and not having any other permission event in the object masks a more likely case than the other way around. Rework the fmode macros and code so that their meaning now refers only to hooks on an already open file: - FMODE_NOTIFY_NONE() skip all events - FMODE_NOTIFY_ACCESS_PERM() send all permission events including FAN_ACCESS_PERM - FMODE_NOTIFY_HSM() send pre-content permission events Signed-off-by: Amir Goldstein <amir73il@gmail.com> Signed-off-by: Jan Kara <jack@suse.cz> Link: https://patch.msgid.link/20250708143641.418603-3-amir73il@gmail.com |

fsnotify: merge file_set_fsnotify_mode_from_watchers() with open perm hook
Create helper fsnotify_open_perm_and_set_mode() that moves the fsnotify_open_perm() hook into file_set_fsnotify_mode_from_watchers(). This will allow some more optimizations.

NFS: Fixup allocation flags for nfsiod's __GFP_NORETRY
If the NFS client is doing writeback from a workqueue context, avoid using
__GFP_NORETRY for allocations if the task has set PF_MEMALLOC_NOIO or
PF_MEMALLOC_NOFS. The combination of these flags makes memory allocation
failures much more likely.
We've seen those allocation failures show up when the loopback driver is
doing writeback from a workqueue to a file on NFS, where memory allocation
failure results in errors or corruption within the loopback device's
filesystem.

NFSD 6.17 Release Notes
NFSD is finally able to offer write delegations to clients that open files with O_WRONLY, thanks to patches from Dai Ngo. We're expecting this to accelerate a few interesting corner cases. The cap on the number of operations per NFSv4 COMPOUND has been lifted. Now, clients that send COMPOUNDs containing dozens of operations (for example, a long stream of LOOKUP operations to walk a pathname in a single round trip) will no longer be rejected. This release re-enables the ability for NFSD to perform NFSv4.2 COPY operations asynchronously. This feature has been disabled to mitigate the risk of denial-of-service when too many such requests arrive. Many thanks to the contributors, reviewers, testers, and bug reporters who participated during the v6.17 development cycle. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmiFJAcACgkQM2qzM29m f5fOvA/+I1W3iAXMeuS4MdBD+20976XZNazXKXXfJE9ay/0I7rXka0uD9HH+cTnU 3wY1p+jjTs+Tatc5A39MjuS9a6o23FnHZB7IOimL+9ASRjBgjXisOyb7yEnfcA4s 9NjM5sMHskmrNpLX5kDPNHzTMdaozGl/uSDKg5WSAU/NMrtAT9c9snx4bO5A6mdk 48XPkP5++aBKGehsPqI0WGOeSzGKI7dc/kJS9F8kIbBCAMJSbIY7PKly+y+fbJkk eMapUX257DCRQejA6hnFff0/x1NnR2tC8lQAZE1c7P5D9CV+1UEAQWK4/OOD2aeQ hY9Ieb7CFZRot3VDGnnrYjLbApiZCY9m10ukDTykPErJ4ZEWEjUtMN7oAhRN3/Ie O2NKvyVo4bOI5zHf4iCIVNp/hDHs01FoMfJfQYRACpBtsIKm+1pn4uTJtrezhJvn qsvctMEMtXwZDlntwhQwU54XJyyGq7gJwuRAZ5xgW6WWQQI+NNKUm2XZu3YwJZF+ 4Ji2vj6kRpS46HWG0VRUX12hXdDZdwFjcZ7eXZiSL3gZJ3xuEJDQ3jyyRwfe5t+8 W6eQRW9Sq1gN4OLwWjfltqs9l52XYfw0jitmX8Y98l1K05a4X74iIPRC5s97HV0E XfvW+jRS4+x7tRp4wwcI2cGTPRTdK8xjmRWM3l2PQzgeG3AHUs8= =rC5G -----END PGP SIGNATURE----- Merge tag 'nfsd-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "NFSD is finally able to offer write delegations to clients that open files with O_WRONLY, thanks to patches from Dai Ngo.
