The work contained in here adds support for case-insensitive file names lookups in tmpfs. The main difference from other casefold filesystems is that tmpfs has no information on disk, just on RAM, so we can't use mkfs to create a case-insensitive tmpfs. For this implementation, there's a mount option for casefolding. The rest of the patchset follows a similar approach as ext4 and f2fs. The use case for this feature is similar to the use case for ext4, to better support compatibility layers (like Wine), particularly in combination with sandboxing/container tools (like Flatpak). Those containerization tools can share a subset of the host filesystem with an application. In the container, the root directory and any parent directories required for a shared directory are on tmpfs, with the shared directories bind-mounted into the container's view of the filesystem. If the host filesystem is using case-insensitive directories, then the application can do lookups inside those directories in a case-insensitive way, without this needing to be implemented in user-space. However, if the host is only sharing a subset of a case-insensitive directory with the application, then the parent directories of the mount point will be part of the container's root tmpfs. When the application tries to do case-insensitive lookups of those parent directories on a case-sensitive tmpfs, the lookup will fail" * tag 'vfs-6.13.tmpfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: tmpfs: Initialize sysfs during tmpfs init tmpfs: Fix type for sysfs' casefold attribute libfs: Fix kernel-doc warning in generic_ci_validate_strict_name docs: tmpfs: Add casefold options tmpfs: Expose filesystem features via sysfs tmpfs: Add flag FS_CASEFOLD_FL support for tmpfs dirs tmpfs: Add casefold lookup support libfs: Export generic_ci_ dentry functions unicode: Recreate utf8_parse_version() unicode: Export latest available UTF-8 version number ext4: Use generic_ci_validate_strict_name helper libfs: Create the helper function generic_ci_validate_strict_name() |

A common pattern when using pidfds is having to get information about the process, which currently requires /proc being mounted, resolving the fd to a pid, and then do manual string parsing of /proc/N/status and friends. This needs to be reimplemented over and over in all userspace projects (e.g.: it has been reimplemented in systemd, dbus, dbus-daemon, polkit so far), and requires additional care in checking that the fd is still valid after having parsed the data, to avoid races. Having a programmatic API that can be used directly removes all these requirements, including having /proc mounted. As discussed at LPC24, add an ioctl with an extensible struct so that more parameters can be added later if needed.

Pull vfs file updates from Christian Brauner:
"This contains changes the changes for files for this cycle:
- Introduce a new reference counting mechanism for files.
As atomic_inc_not_zero() is implemented with a try_cmpxchg() loop
it has O(N^2) behaviour under contention with N concurrent
operations and it is in a hot path in __fget_files_rcu().
The rcuref infrastructures remedies this problem by using an
unconditional increment relying on safe- and dead zones to make
this work and requiring rcu protection for the data structure in
question. This not just scales better it also introduces overflow
protection.
However, in contrast to generic rcuref, files require a memory
barrier and thus cannot rely on *_relaxed() atomic operations and
also require to be built on atomic_long_t as having massive amounts
of reference isn't unheard of even if it is just an attack.
This adds a file specific variant instead of making this a generic
library.
This has been tested by various people and it gives consistent
improvement up to 3-5% on workloads with loads of threads.
- Add a fastpath for find_next_zero_bit(). Skip 2-levels searching
via find_next_zero_bit() when there is a free slot in the word that
contains the next fd. This improves pts/blogbench-1.1.0 read by 8%
and write by 4% on Intel ICX 160.
- Conditionally clear full_fds_bits since it's very likely that a bit
in full_fds_bits has been cleared during __clear_open_fds(). This
improves pts/blogbench-1.1.0 read up to 13%, and write up to 5% on
Intel ICX 160.
- Get rid of all lookup_*_fdget_rcu() variants. They were used to
lookup files without taking a reference count. That became invalid
once files were switched to SLAB_TYPESAFE_BY_RCU and now we're
always taking a reference count. Switch to an already existing
helper and remove the legacy variants.
- Remove pointless includes of <linux/fdtable.h>.
- Avoid cmpxchg() in close_files() as nobody else has a reference to
the files_struct at that point.
- Move close_range() into fs/file.c and fold __close_range() into it.
- Cleanup calling conventions of alloc_fdtable() and expand_files().
- Merge __{set,clear}_close_on_exec() into one.
- Make __set_open_fd() set cloexec as well instead of doing it in two
separate steps"

Pull misc vfs updates from Christian Brauner:
"Features:
- Fixup and improve NLM and kNFSD file lock callbacks
Last year both GFS2 and OCFS2 had some work done to make their
locking more robust when exported over NFS. Unfortunately, part of
that work caused both NLM (for NFS v3 exports) and kNFSD (for
NFSv4.1+ exports) to no longer send lock notifications to clients
This in itself is not a huge problem because most NFS clients will
still poll the server in order to acquire a conflicted lock
It's important for NLM and kNFSD that they do not block their
kernel threads inside filesystem's file_lock implementations
because that can produce deadlocks. We used to make sure of this by
only trusting that posix_lock_file() can correctly handle blocking
lock calls asynchronously, so the lock managers would only setup
their file_lock requests for async callbacks if the filesystem did
not define its own lock() file operation
However, when GFS2 and OCFS2 grew the capability to correctly
handle blocking lock requests asynchronously, they started
signalling this behavior with EXPORT_OP_ASYNC_LOCK, and the check
for also trusting posix_lock_file() was inadvertently dropped, so
now most filesystems no longer produce lock notifications when
exported over NFS
Fix this by using an fop_flag which greatly simplifies the problem
and grooms the way for future uses by both filesystems and lock
managers alike
- Add a sysctl to delete the dentry when a file is removed instead of
making it a negative dentry

Pull vfs multigrain timestamps from Christian Brauner:
"This is another try at implementing multigrain timestamps. This time
with significant help from the timekeeping maintainers to reduce the
performance impact.
Thomas provided a base branch that contains the required timekeeping
interfaces for the VFS. It serves as the base for the multi-grain
timestamp work:
- Multigrain timestamps allow the kernel to use fine-grained
timestamps when an inode's attributes is being actively observed
via ->getattr(). With this support, it's possible for a file to get
a fine-grained timestamp, and another modified after it to get a
coarse-grained stamp that is earlier than the fine-grained time. If
this happens then the files can appear to have been modified in
reverse order, which breaks VFS ordering guarantees.
To prevent this, a floor value is maintained for multigrain
timestamps. Whenever a fine-grained timestamp is handed out, record
it, and when later coarse-grained stamps are handed out, ensure
they are not earlier than that value. If the coarse-grained
timestamp is earlier than the fine-grained floor, return the floor
value instead.
The timekeeper changes add a static singleton atomic64_t into
timekeeper.c that is used to keep track of the latest fine-grained
time ever handed out. This is tracked as a monotonic ktime_t value
to ensure that it isn't affected by clock jumps. Because it is
updated at different times than the rest of the timekeeper object,
the floor value is managed independently of the timekeeper via a
cmpxchg() operation, and sits on its own cacheline.
Two new public timekeeper interfaces are added:
(1) ktime_get_coarse_real_ts64_mg() fills a timespec64 with the
later of the coarse-grained clock and the floor time
(2) ktime_get_real_ts64_mg() gets the fine-grained clock value,
and tries to swap it into the floor. A timespec64 is filled
with the result.
- The VFS has always used coarse-grained timestamps when updating the
ctime and mtime after a change. This has the benefit of allowing
filesystems to optimize away a lot metadata updates, down to around
1 per jiffy, even when a file is under heavy writes.
Unfortunately, this has always been an issue when we're exporting
via NFSv3, which relies on timestamps to validate caches. A lot of
changes can happen in a jiffy, so timestamps aren't sufficient to
help the client decide when to invalidate the cache. Even with
NFSv4, a lot of exported filesystems don't properly support a
change attribute and are subject to the same problems with
timestamp granularity. Other applications have similar issues with
timestamps (e.g backup applications).
If we were to always use fine-grained timestamps, that would
improve the situation, but that becomes rather expensive, as the
underlying filesystem would have to log a lot more metadata
updates.
This adds a way to only use fine-grained timestamps when they are
being actively queried. Use the (unused) top bit in
inode->i_ctime_nsec as a flag that indicates whether the current
timestamps have been queried via stat() or the like. When it's set,
we allow the kernel to use a fine-grained timestamp iff it's
necessary to make the ctime show a different value.
This solves the problem of being able to distinguish the timestamp
between updates, but introduces a new problem: it's now possible
for a file being changed to get a fine-grained timestamp. A file
that is altered just a bit later can then get a coarse-grained one
that appears older than the earlier fine-grained time. This
violates timestamp ordering guarantees.
This is where the earlier mentioned timkeeping interfaces help. A
global monotonic atomic64_t value is kept that acts as a timestamp
floor. When we go to stamp a file, we first get the latter of the
current floor value and the current coarse-grained time. If the
inode ctime hasn't been queried then we just attempt to stamp it
with that value.
If it has been queried, then first see whether the current coarse
time is later than the existing ctime. If it is, then we accept
that value. If it isn't, then we get a fine-grained time and try to
swap that into the global floor. Whether that succeeds or fails, we
take the resulting floor time, convert it to realtime and try to
swap that into the ctime.
We take the result of the ctime swap whether it succeeds or fails,
since either is just as valid.
Filesystems can opt into this by setting the FS_MGTIME fstype flag.
Others should be unaffected (other than being subject to the same
floor value as multigrain filesystems)"

When 'ioctl(OCFS2_IOC_GROUP_ADD, ...)' has failed for the particular
inode in 'ocfs2_verify_group_and_input()', corresponding buffer head
remains cached and subsequent call to the same 'ioctl()' for the same
inode issues the BUG() in 'ocfs2_set_new_buffer_uptodate()' (trying
to cache the same buffer head of that inode). Fix this by uncaching
the buffer head with 'ocfs2_remove_from_cache()' on error path in
'ocfs2_group_add()'.

We triggered a NULL pointer dereference for ac.preferred_zoneref->zone in alloc_pages_bulk_noprof() when the task is migrated between cpusets. When cpuset is enabled, in prepare_alloc_pages(), ac->nodemask may be ¤t->mems_allowed. when first_zones_zonelist() is called to find preferred_zoneref, the ac->nodemask may be modified concurrently if the task is migrated between different cpusets. Assuming we have 2 NUMA Node, when traversing Node1 in ac->zonelist, the nodemask is 2, and when traversing Node2 in ac->zonelist, the nodemask is 1. As a result, the ac->preferred_zoneref points to NULL zone. In alloc_pages_bulk_noprof(), for_each_zone_zonelist_nodemask() finds a allowable zone and calls zonelist_node_idx(ac.preferred_zoneref), leading to NULL pointer dereference. __alloc_pages_noprof() fixes this issue by checking NULL pointer in commit |

fs/proc/task_mmu: prevent integer overflow in pagemap_scan_get_args()
The "arg->vec_len" variable is a u64 that comes from the user at the start
of the function. The "arg->vec_len * sizeof(struct page_region))"
multiplication can lead to integer wrapping. Use size_mul() to avoid
that.
Also the size_add/mul() functions work on unsigned long so for 32bit
systems we need to ensure that "arg->vec_len" fits in an unsigned long.

sched/task_stack: fix object_is_on_stack() for KASAN tagged pointers
When CONFIG_KASAN_SW_TAGS and CONFIG_KASAN_STACK are enabled, the object_is_on_stack() function may produce incorrect results due to the presence of tags in the obj pointer, while the stack pointer does not have tags. This discrepancy can lead to incorrect stack object detection and subsequently trigger warnings if CONFIG_DEBUG_OBJECTS is also enabled. Example of the warning: ODEBUG: object 3eff800082ea7bb0 is NOT on stack ffff800082ea0000, but annotated. ------------[ cut here ]------------ WARNING: CPU: 0 PID: 1 at lib/debugobjects.c:557 __debug_object_init+0x330/0x364 Modules linked in: CPU: 0 UID: 0 PID: 1 Comm: swapper/0 Not tainted 6.12.0-rc5 #4 Hardware name: linux,dummy-virt (DT) pstate: 600000c5 (nZCv daIF -PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : __debug_object_init+0x330/0x364 lr : __debug_object_init+0x330/0x364 sp : ffff800082ea7b40 x29: ffff800082ea7b40 x28: 98ff0000c0164518 x27: 98ff0000c0164534 x26: ffff800082d93ec8 x25: 0000000000000001 x24: 1cff0000c00172a0 x23: 0000000000000000 x22: ffff800082d93ed0 x21: ffff800081a24418 x20: 3eff800082ea7bb0 x19: efff800000000000 x18: 0000000000000000 x17: 00000000000000ff x16: 0000000000000047 x15: 206b63617473206e x14: 0000000000000018 x13: ffff800082ea7780 x12: 0ffff800082ea78e x11: 0ffff800082ea790 x10: 0ffff800082ea79d x9 : 34d77febe173e800 x8 : 34d77febe173e800 x7 : 0000000000000001 x6 : 0000000000000001 x5 : feff800082ea74b8 x4 : ffff800082870a90 x3 : ffff80008018d3c4 x2 : 0000000000000001 x1 : ffff800082858810 x0 : 0000000000000050 Call trace: __debug_object_init+0x330/0x364 debug_object_init_on_stack+0x30/0x3c schedule_hrtimeout_range_clock+0xac/0x26c schedule_hrtimeout+0x1c/0x30 wait_task_inactive+0x1d4/0x25c kthread_bind_mask+0x28/0x98 init_rescuer+0x1e8/0x280 workqueue_init+0x1a0/0x3cc kernel_init_freeable+0x118/0x200 kernel_init+0x28/0x1f0 ret_from_fork+0x10/0x20 ---[ end trace 0000000000000000 ]--- ODEBUG: object 3eff800082ea7bb0 is NOT on stack ffff800082ea0000, but annotated. ------------[ cut here ]------------ Link: https://lkml.kernel.org/r/20241113042544.19095-1-qun-wei.lin@mediatek.com Signed-off-by: Qun-Wei Lin <qun-wei.lin@mediatek.com> Cc: Andrew Yang <andrew.yang@mediatek.com> Cc: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com> Cc: Casper Li <casper.li@mediatek.com> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Chinwen Chang <chinwen.chang@mediatek.com> Cc: Kent Overstreet <kent.overstreet@linux.dev> Cc: Matthias Brugger <matthias.bgg@gmail.com> Cc: Pasha Tatashin <pasha.tatashin@soleen.com> Cc: Shakeel Butt <shakeel.butt@linux.dev> Cc: <stable@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> |

crash, powerpc: default to CRASH_DUMP=n on PPC_BOOK3S_32
Fixes boot failures on 6.9 on PPC_BOOK3S_32 machines using Open Firmware.
On these machines, the kernel refuses to boot from non-zero
PHYSICAL_START, which occurs when CRASH_DUMP is on.
Since most PPC_BOOK3S_32 machines boot via Open Firmware, it should
default to off for them. Users booting via some other mechanism can still
turn it on explicitly.
Does not change the default on any other architectures for the
time being.

mm/mremap: fix address wraparound in move_page_tables()
On 32-bit platforms, it is possible for the expression `len + old_addr <
old_end` to be false-positive if `len + old_addr` wraps around.
`old_addr` is the cursor in the old range up to which page table entries
have been moved; so if the operation succeeded, `old_addr` is the *end* of
the old region, and adding `len` to it can wrap.
The overflow causes mremap() to mistakenly believe that PTEs have been
copied; the consequence is that mremap() bails out, but doesn't move the
PTEs back before the new VMA is unmapped, causing anonymous pages in the
region to be lost. So basically if userspace tries to mremap() a
private-anon region and hits this bug, mremap() will return an error and
the private-anon region's contents appear to have been zeroed.
The idea of this check is that `old_end - len` is the original start
address, and writing the check that way also makes it easier to read; so
fix the check by rearranging the comparison accordingly.
(An alternate fix would be to refactor this function by introducing an
"orig_old_start" variable or such.)
Tested in a VM with a 32-bit X86 kernel; without the patch:

printf("mremap() failed; first char is 0x%02hhx\n", *p1);
} else {

mm, swap: fix allocation and scanning race with swapoff
There are two flags used to synchronize allocation and scanning with swapoff: SWP_WRITEOK and SWP_SCANNING. SWP_WRITEOK: Swapoff will first unset this flag, at this point any further swap allocation or scanning on this device should just abort so no more new entries will be referencing this device. Swapoff will then unuse all existing swap entries. SWP_SCANNING: This flag is set when device is being scanned. Swapoff will wait for all scanner to stop before the final release of the swap device structures to avoid UAF. Note this flag is the highest used bit of si->flags so it could be added up arithmetically, if there are multiple scanner. commit |

SCX_KF_UNLOCKED which allows all unlocked kfuncs, but ops.cpu_acquire() is

kfuncs that are safe under the rq lock. Update it to use SCX_KF_REST.
