nilfs2: replace WARN_ONs by nilfs_error for checkpoint acquisition failure
If creation or finalization of a checkpoint fails due to anomalies in the checkpoint metadata on disk, a kernel warning is generated. This patch replaces the WARN_ONs by nilfs_error, so that a kernel, booted with panic_on_warn, does not panic. A nilfs_error is appropriate here to handle the abnormal filesystem condition. This also replaces the detected error codes with an I/O error so that neither of the internal error codes is returned to callers.

"There are relatively few updates this cycle; half the cycle was eaten
by a grue, the other half was eaten by a tricky data corruption issue
that I still haven't entirely solved.
Hence there's no major changes in this cycle and it's largely just
minor cleanups and small bug fixes:
- fixes for filesystem shutdown procedure during a DAX memory failure
notification
- bug fixes
- logic cleanups
- log message cleanups
- updates to use vfs{g,u}id_t helpers where appropriate"

f2fs-for-6.1-rc1
This round looks fairly small comparing to the previous updates which includes
mostly minor bug fixes. Nevertheless, as we've still interested in improving
the stability, Chao added some debugging methods to diagnoze subtle runtime
inconsistency problem.
Enhancement
- store all the corruption or failure reasons in superblock
- detect meta inode, summary info, and block address inconsistency
- increase the limit for reserve_root for low-end devices
- add the number of compressed IO in iostat
Bug fix
- DIO write fix for zoned devices
- do out-of-place writes for cold files
- fix some stat updates (FS_CP_DATA_IO, dirty page count)
- fix race condition on setting FI_NO_EXTENT flag
- fix data races when freezing super
- fix wrong continue condition check in GC
- do not allow ATGC for LFS mode
In addition, there're some code enhancement and clean-ups as usual.

gfs2 fixes
- Make sure to initialize the filesystem work queues before registering the filesystem; this prevents them from being used uninitialized. - On filesystem withdraw: prevent a a double iput() and immediately reject pending locking requests that can no longer succeed. - Use TRY lock in gfs2_inode_lookup() to prevent a rare glock hang during evict. - During filesystem mount, explicitly make sure that the sb_bsize and sb_bsize_shift super block fields are consistent with each other. This prevents messy error messages during fuzz testing. - Switch from strlcpy to strscpy. -----BEGIN PGP SIGNATURE----- iQJIBAABCAAyFiEEJZs3krPW0xkhLMTc1b+f6wMTZToFAmNCoXgUHGFncnVlbmJh QHJlZGhhdC5jb20ACgkQ1b+f6wMTZTph4xAAg+SnmCkvh07ww1CLLGxPWFK41toZ zBYbwXb3h4qeFXQ4XSI4ZYnAjWTwIK0yjz0lp6pRnEoh0ih+IuEuIZLVls/ggEn6 /BxRDKWHE6fJwkemsB/V8XAu3UTemG0BOo6kkoYYnkjd5qZuqcqMkUEvc4xwsIxu 2tfzKfPoIgn95HVjiQboViwEEa/HzwaxxudWaVoa/Gn54wWxFfrQplGoYftS/8ah 5d0ho1hOLPXJNNeKUXVnu8buKs3Oh59OpMXoI4gzvUfh2YWYqm5giP0Dwnv5qf6F NeMFqUxUKoMKL5nofkWI6FqRoWLbmattrL8nu0Fpn/tlzuMivlI25PB4k37R3tGx GILncsnLOMxzUx69aTnZLyn/8RWkgiHaQ3Nm4OJPTENd7/V7o/5O1BRInRzdeHdN LEfD6Fsi+muK5V6aIe1LIELSB0i/C7753pF0BWQ93KItE6hpufTct9YPXgmn+k/v gxHy+laPWhKXdPriBnO6RyeV7DJr/Ai+7ga3e35UxRqr9DvIpltNUvODqxyXPymS EIC45zQD6fVLOIFCxwLPrTbc2isrcvu+TYlcByaUVSc5weK3ZbdWz4Pm3Wd59K3n 7oJRx6oWMemVcTgUsZQ7Lr7lPlM47O9kiUJy9RNCeefPChQ/5+OgxfKOcdqQZK8E z4a3efQ5APqp308= =h/LV -----END PGP SIGNATURE----- Merge tag 'gfs2-v6.0-rc2-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2 Pull gfs2 updates from Andreas Gruenbacher: - Make sure to initialize the filesystem work queues before registering the filesystem; this prevents them from being used uninitialized. - On filesystem withdraw: prevent a a double iput() and immediately reject pending locking requests that can no longer succeed. - Use TRY lock in gfs2_inode_lookup() to prevent a rare glock hang during evict. - During filesystem mount, explicitly make sure that the sb_bsize and sb_bsize_shift super block fields are consistent with each other.

- Yu Zhao's Multi-Gen LRU patches are here. They've been under test in
linux-next for a couple of months without, to my knowledge, any negative reports (or any positive ones, come to that). - Also the Maple Tree from Liam R. Howlett. An overlapping range-based tree for vmas. It it apparently slight more efficient in its own right, but is mainly targeted at enabling work to reduce mmap_lock contention. Liam has identified a number of other tree users in the kernel which could be beneficially onverted to mapletrees. Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat (https://lkml.kernel.org/r/CAOUHufZabH85CeUN-MEMgL8gJGzJEWUrkiM58JkTbBhh-jew0Q@mail.gmail.com). This has yet to be addressed due to Liam's unfortunately timed vacation. He is now back and we'll get this fixed up. - Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer.

An overlapping range-based tree for vmas. It it apparently slightly more efficient in its own right, but is mainly targeted at enabling work to reduce mmap_lock contention. Liam has identified a number of other tree users in the kernel which could be beneficially onverted to mapletrees. Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat at [1].

bitmap patches for v6.1-rc1
From Phil Auld:
drivers/base: Fix unsigned comparison to -1 in CPUMAP_FILE_MAX_BYTES
From me:
cpumask: cleanup nr_cpu_ids vs nr_cpumask_bits mess
This series cleans that mess and adds new config FORCE_NR_CPUS that
allows to optimize cpumask subsystem if the number of CPUs is known
at compile-time.
From me:
lib: optimize find_bit() functions
Reworks find_bit() functions based on new FIND_{FIRST,NEXT}_BIT() macros.
From me:
lib/find: add find_nth_bit()
Adds find_nth_bit(), which is ~70 times faster than bitcounting with
for_each() loop:
for_each_set_bit(bit, mask, size)
if (n-- == 0)
return bit;
Also adds bitmap_weight_and() to let people replace this pattern:
tmp = bitmap_alloc(nbits);
bitmap_and(tmp, map1, map2, nbits);
weight = bitmap_weight(tmp, nbits);
bitmap_free(tmp);
with a single bitmap_weight_and() call.
From me:
cpumask: repair cpumask_check()
After switching cpumask to use nr_cpu_ids, cpumask_check() started
generating many false-positive warnings. This series fixes it.
From Valentin Schneider:
bitmap,cpumask: Add for_each_cpu_andnot() and for_each_cpu_andnot()
Extends the API with one more function and applies it in sched/core.

Preempt RT cleanups:
Introduce preempt_[dis|enable_nested() and use it to clean up various places which have open coded PREEMPT_RT conditionals. On PREEMPT_RT enabled kernels, spinlocks and rwlocks are neither disabling preemption nor interrupts. Though there are a few places which depend on the implicit preemption/interrupt disable of those locks, e.g. seqcount write sections, per CPU statistics updates etc. PREEMPT_RT added open coded CONFIG_PREEMPT_RT conditionals to disable/enable preemption in the related code parts all over the place. That's hard to read and does not really explain why this is necessary. Linus suggested to use helper functions (preempt_disable_nested() and preempt_enable_nested()) and use those in the affected places. On !RT enabled kernels these functions are NOPs, but contain a lockdep assert to validate that preemption is actually disabled to catch call sites which do not have preemption disabled.

ucounts: Split rlimit and ucount values and max values
After the ucount rlimit code was merged a bunch of small but
siginificant bugs were found and fixed. At the time it was realized
that part of the problem was that while the ucount rlimits were very
similar to the oridinary ucounts (in being nested counts with limits)
the semantics were slightly different and the code would be less error
prone if there was less sharing. This is the long awaited cleanup
that should hopefully keep things more comprehensible and less error
prone for whoever needs to touch that code next.

ptrace: Stop supporting SIGKILL for PTRACE_EVENT_EXIT
Recently I had a conversation where it was pointed out to me that
SIGKILL sent to a tracee stropped in PTRACE_EVENT_EXIT is quite
difficult for a tracer to handle.
Keeping SIGKILL working after the process has been killed is pain
from an implementation point of view.
So since the debuggers don't want this behavior let's see if we can
remove this wart for the userspace API
If a regression is detected it should only need to be the last change
that is the reverted. The other two are just general cleanups that
make the last patch simpler.

signal: Ensure SIGNAL_GROUP_EXIT gets set in do_group_exit
signal: Guarantee that SIGNAL_GROUP_EXIT is set on process exit

The first batch of KVM patches, mostly covering x86, which I
am sending out early due to me travelling next week. There is a lone mm patch for which Andrew gave an informal ack at https://lore.kernel.org/linux-mm/20220817102500.440c6d0a3fce296fdf91bea6@linux-foundation.org. I will send the bulk of ARM work, as well as other architectures, at the end of next week. ARM: * Account stage2 page table allocations in memory stats. x86: * Account EPT/NPT arm64 page table allocations in memory stats. * Tracepoint cleanups/fixes for nested VM-Enter and emulated MSR accesses. * Drop eVMCS controls filtering for KVM on Hyper-V, all known versions of Hyper-V now support eVMCS fields associated with features that are enumerated to the guest. * Use KVM's sanitized VMCS config as the basis for the values of nested VMX capabilities MSRs. * A myriad event/exception fixes and cleanups. Most notably, pending exceptions morph into VM-Exits earlier, as soon as the exception is queued, instead of waiting until the next vmentry. This fixed a longstanding issue where the exceptions would incorrecly become double-faults instead of triggering a vmexit; the common case of page-fault vmexits had a special workaround, but now it's fixed for good. * A handful of fixes for memory leaks in error paths. * Cleanups for VMREAD trampoline and VMX's VM-Exit assembly flow. * Never write to memory from non-sleepable kvm_vcpu_check_block() * Selftests refinements and cleanups. * Misc typo cleanups. Generic: * remove KVM_REQ_UNHALT -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEE8TM4V0tmI4mGbHaCv/vSX3jHroMFAmM2zwcUHHBib256aW5p QHJlZGhhdC5jb20ACgkQv/vSX3jHroNpbwf+MlVeOlzE5SBdrJ0TEnLmKUel1lSz QnZzP5+D65oD0zhCilUZHcg6G4mzZ5SdVVOvrGJvA0eXh25ruLNMF6jbaABkMLk/ FfI1ybN7A82hwJn/aXMI/sUurWv4Jteaad20JC2DytBCnsW8jUqc49gtXHS2QWy4 3uMsFdpdTAg4zdJKgEUfXBmQviweVpjjl3ziRyZZ7yaeo1oP7XZ8LaE1nR2l5m0J mfjzneNm5QAnueypOh5KhSwIvqf6WHIVm/rIHDJ1HIFbgfOU0dT27nhb1tmPwAcE +cJnnMUHjZqtCXteHkAxMClyRq0zsEoKk0OGvSOOMoq3Q0DavSXUNANOig== =/hqX -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull kvm updates from Paolo Bonzini: "The first batch of KVM patches, mostly covering x86.

cifs: secmech: use shash_desc directly, remove sdesc
The struct sdesc is just a wrapper around shash_desc, with exact same
memory layout. Replace the hashing TFMs with shash_desc as it's what's
passed to the crypto API anyway.
Also remove the crypto_shash pointers as they can be accessed via
shash_desc->tfm (and are actually only used in the setkey calls).
Adapt cifs_{alloc,free}_hash functions to this change.

Driver core changes for 6.1-rc1
Here is the big set of driver core and debug printk changes for 6.1-rc1.
Included in here is:
- dynamic debug updates for the core and the drm subsystem. The
drm changes have all been acked by the relevant maintainers.
- kernfs fixes for syzbot reported problems
- kernfs refactors and updates for cgroup requirements
- magic number cleanups and removals from the kernel tree (they
were not being used and they really did not actually do
anything.)
- other tiny cleanups
All of these have been in linux-next for a while with no reported
issues.

The first two changes that involve files outside of fs/ext4:
- submit_bh() can never return an error, so change it to return void,
and remove the unused checks from its callers
- fix I_DIRTY_TIME handling so it will be set even if the inode
already has I_DIRTY_INODE
Performance:
- Always enable i_version counter (as btrfs and xfs already do).
Remove some uneeded i_version bumps to avoid unnecessary nfs cache
invalidations.
- Wake up journal waters in FIFO order, to avoid some journal users
from not getting a journal handle for an unfairly long time.
- In ext4_write_begin() allocate any necessary buffer heads before
starting the journal handle.
- Don't try to prefetch the block allocation bitmaps for a read-only
file system.
Bug Fixes:
- Fix a number of fast commit bugs, including resources leaks and out
of bound references in various error handling paths and/or if the fast
commit log is corrupted.
- Avoid stopping the online resize early when expanding a file system
which is less than 16TiB to a size greater than 16TiB.
- Fix apparent metadata corruption caused by a race with a metadata
buffer head getting migrated while it was trying to be read.
- Mark the lazy initialization thread freezable to prevent suspend
failures.
- Other miscellaneous bug fixes.
Cleanups:
- Break up the incredibly long ext4_full_super() function by
refactoring to move code into more understandable, smaller
functions.
- Remove the deprecated (and ignored) noacl and nouser_attr mount
option.
- Factor out some common code in fast commit handling.
- Other miscellaneous cleanups.

Pull btrfs updates from David Sterba:
"There's a bunch of performance improvements, most notably the FIEMAP
speedup, the new block group tree to speed up mount on large
filesystems, more io_uring integration, some sysfs exports and the
usual fixes and core updates.
Summary:
Performance:
- outstanding FIEMAP speed improvement
- algorithmic change how extents are enumerated leads to orders of
magnitude speed boost (uncached and cached)
- extent sharing check speedup (2.2x uncached, 3x cached)
- add more cancellation points, allowing to interrupt seeking in
files with large number of extents
- more efficient hole and data seeking (4x uncached, 1.3x cached)
- sample results:
256M, 32K extents: 4s -> 29ms (~150x)
512M, 64K extents: 30s -> 59ms (~550x)
1G, 128K extents: 225s -> 120ms (~1800x)
- improved inode logging, especially for directories (on dbench
workload throughput +25%, max latency -21%)
- improved buffered IO, remove redundant extent state tracking,
lowering memory consumption and avoiding rb tree traversal
- add sysfs tunable to let qgroup temporarily skip exact accounting
when deleting snapshot, leading to a speedup but requiring a rescan
after that, will be used by snapper
- support io_uring and buffered writes, until now it was just for
direct IO, with the no-wait semantics implemented in the buffered
write path it now works and leads to speed improvement in IOPS
(2x), throughput (2.2x), latency (depends, 2x to 150x)
- small performance improvements when dropping and searching for
extent maps as well as when flushing delalloc in COW mode
(throughput +5MB/s)
User visible changes:
- new incompatible feature block-group-tree adding a dedicated tree
for tracking block groups, this allows a much faster load during
mount and avoids seeking unlike when it's scattered in the extent
tree items
- this reduces mount time for many-terabyte sized filesystems
- conversion tool will be provided so existing filesystem can also
be updated in place
- to reduce test matrix and feature combinations requires no-holes
and free-space-tree (mkfs defaults since 5.15)
- improved reporting of super block corruption detected by scrub
- scrub also tries to repair super block and does not wait until next
commit
- discard stats and tunables are exported in sysfs
(/sys/fs/btrfs/FSID/discard)
- qgroup status is exported in sysfs
(/sys/sys/fs/btrfs/FSID/qgroups/)
- verify that super block was not modified when thawing filesystem
Fixes:
- FIEMAP fixes
- fix extent sharing status, does not depend on the cached status
where merged
- flush delalloc so compressed extents are reported correctly
- fix alignment of VMA for memory mapped files on THP
- send: fix failures when processing inodes with no links (orphan
files and directories)
- fix race between quota enable and quota rescan ioctl
- handle more corner cases for read-only compat feature verification
- fix missed extent on fsync after dropping extent maps
Core:
- lockdep annotations to validate various transactions states and
state transitions
- preliminary support for fs-verity in send
- more effective memory use in scrub for subpage where sector is
smaller than page
- block group caching progress logic has been removed, load is now
synchronous
- simplify end IO callbacks and bio handling, use chained bios
instead of own tracking
- add no-wait semantics to several functions (tree search, nocow,
flushing, buffered write
- cleanups and refactoring
MM changes:
- export balance_dirty_pages_ratelimited_flags"

cifs: Replace a couple of one-element arrays with flexible-array members
One-element arrays are deprecated, and we are replacing them with flexible array members instead. So, replace one-element arrays with flexible-array member in structs negotiate_req and extended_response, and refactor the rest of the code, accordingly. Also, make use of the DECLARE_FLEX_ARRAY() helper to declare flexible array member EncryptionKey in union u. This new helper allows for flexible-array members in unions. Change pointer notation to proper array notation in a call to memcpy() where flexible-array member DialectsArray is being used as destination argument. Important to mention is that doing a build before/after this patch results in no binary output differences. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays=3 [1].

smb3: do not log confusing message when server returns no network interfaces
Some servers can return an empty network interface list so, unless multichannel is requested, no need to log an error for this, and when multichannel is requested on mount but no interfaces, log something less confusing. For this case change parse_server_interfaces: malformed interface info to empty network interface list returned by server localhost Also do not relog this error every ten minutes (only log on mount, once) Cc: <stable@vger.kernel.org> Reviewed-by: Paulo Alcantara (SUSE) <pc@cjr.nz> Signed-off-by: Steve French <stfrench@microsoft.com> |

nfsd: rework hashtable handling in nfsd_do_file_acquire
nfsd_file is RCU-freed, so we need to hold the rcu_read_lock long enough to get a reference after finding it in the hash. Take the rcu_read_lock() and call rhashtable_lookup directly. Switch to using rhashtable_lookup_insert_key as well, and use the usual retry mechanism if we hit an -EEXIST. Rename the "retry" bool to open_retry, and eliminiate the insert_err goto target.

nfsd: fix nfsd_file_unhash_and_dispose
nfsd_file_unhash_and_dispose() is called for two reasons: We're either shutting down and purging the filecache, or we've gotten a notification about a file delete, so we want to go ahead and unhash it so that it'll get cleaned up when we close. We're either walking the hashtable or doing a lookup in it and we don't take a reference in either case. What we want to do in both cases is to try and unhash the object and put it on the dispose list if that was successful. If it's no longer hashed, then we don't want to touch it, with the assumption being that something else is already cleaning up the sentinel reference. Instead of trying to selectively decrement the refcount in this function, just unhash it, and if that was successful, move it to the dispose list. Then, the disposal routine will just clean that up as usual. Also, just make this a void function, drop the WARN_ON_ONCE, and the comments about deadlocking since the nature of the purported deadlock is no longer clear.
