... or visible outside of audit, really. Note that references
held in delayed_filename always have refcount 1, and from the
moment of complete_getname() or equivalent point in getname...()
there won't be any references to struct filename instance left
in places visible to other threads.

There are two filename-related problems in io_uring and its
interplay with audit.
Filenames are imported when request is submitted and used when
it is processed. Unfortunately, the latter may very well
happen in a different thread. In that case the reference to
filename is put into the wrong audit_context - that of submitting
thread, not the processing one. Audit logics is called by
the latter, and it really wants to be able to find the names
in audit_context current (== processing) thread.
Another related problem is the headache with refcounts -
normally all references to given struct filename are visible
only to one thread (the one that uses that struct filename).
io_uring violates that - an extra reference is stashed in
audit_context of submitter. It gets dropped when submitter
returns to userland, which can happen simultaneously with
processing thread deciding to drop the reference it got.
We paper over that by making refcount atomic, but that means
pointless headache for everyone.
Solution: the notion of partially imported filenames. Namely,
already copied from userland, but *not* exposed to audit yet.
io_uring can create that in submitter thread, and complete the
import (obtaining the usual reference to struct filename) in
processing thread.
Object: struct delayed_filename.
Primitives for working with it:
delayed_getname(&delayed_filename, user_string) - copies the name from
userland, returning 0 and stashing the address of (still incomplete)
struct filename in delayed_filename on success and returning -E... on
error.
delayed_getname_uflags(&delayed_filename, user_string, atflags) -
similar, in the same relation to delayed_getname() as getname_uflags()
is to getname()
complete_getname(&delayed_filename) - completes the import of filename
stashed in delayed_filename and returns struct filename to caller,
emptying delayed_filename.
CLASS(filename_complete_delayed, name)(&delayed_filename) - variant of
CLASS(filename) with complete_getname() for constructor.
dismiss_delayed_filename(&delayed_filename) - destructor; drops whatever
might be stashed in delayed_filename, emptying it.
putname_to_delayed(&delayed_filename, name) - if name is shared, stashes
its copy into delayed_filename and drops the reference to name, otherwise
stashes the name itself in there.

Always allocate struct filename from names_cachep, long name or short;
short names would be embedded into struct filename. Longer ones do
not cannibalize the original struct filename - put them into kmalloc'ed
buffers (PATH_MAX-sized for import from userland, strlen() + 1 - for
ones originating kernel-side, where we know the length beforehand).
Cutoff length for short names is chosen so that struct filename would be
192 bytes long - that's both a multiple of 64 and large enough to cover
the majority of real-world uses.
Simplifies logics in getname()/putname() and friends.

Instances of struct filename come from names_cachep (via
__getname()). That is done by getname_flags() and getname_kernel()
and these two are the main callers of __getname(). However, there are
other callers that simply want to allocate PATH_MAX bytes for uses that
have nothing to do with struct filename.
We want saner allocation rules for long pathnames, so that struct
filename would *always* come from names_cachep, with the out-of-line
pathname getting kmalloc'ed. For that we need to be able to change the
size of objects allocated by getname_flags()/getname_kernel().
That requires the rest of __getname() users to stop using
names_cachep; we could explicitly switch all of those to kmalloc(),
but that would cause quite a bit of noise. So the plan is to switch
getname_...() to new helpers and turn __getname() into a wrapper for
kmalloc(). Remaining __getname() users could be converted to explicit
kmalloc() at leisure, hopefully along with figuring out what size do
they really want - PATH_MAX is an overkill for some of them, used out
of laziness ("we have a convenient helper that does 4K allocations and
that's large enough, let's use it").
As a side benefit, names_cachep is no longer used outside
of fs/namei.c, so we can move it there and be done with that.

Originally we tried to avoid multiple insertions into audit names array
during retry loop by a cute hack - memorize the userland pointer and
if there already is a match, just grab an extra reference to it.
Cute as it had been, it had problems - two identical pointers had
audit aux entries merged, two identical strings did not. Having
different behaviour for syscalls that differ only by addresses of
otherwise identical string arguments is obviously wrong - if nothing
else, compiler can decide to merge identical string literals.
Besides, this hack does nothing for non-audited processes - they get
a fresh copy for retry. It's not time-critical, but having behaviour
subtly differ that way is bogus.
These days we have very few places that import filename more than once
(9 functions total) and it's easy to massage them so we get rid of all
re-imports. With that done, we don't need audit_reusename() anymore.
There's no need to memorize userland pointer either.

Not all users match that model, but most of them do. By the end of
the series we'll be left with very few irregular ones...
Added:
CLASS(filename, name)(user_path) =>
getname(user_path)
CLASS(filename_kernel, name)(string) =>
getname_kernel(string)
CLASS(filename_flags, name)(user_path, flags) =>
getname_flags(user_path, flags)
CLASS(filename_uflags, name)(user_path, flags) =>
getname_uflags(user_path, flags)
CLASS(filename_maybe_null, name)(user_path, flags) =>
getname_maybe_null(user_path, flags)
all with putname() as destructor.
"flags" in filename_flags is in LOOKUP_... space, only LOOKUP_EMPTY matters.
"flags" in filename_uflags and filename_maybe_null is in AT_...... space,
and only AT_EMPTY_PATH matters.
filename_flags conventions might be worth reconsidering later (it might or
might not be better off with boolean instead)

- Re-add #ifdef guards around PIDFD_GET_<ns-type>_NAMESPACE ioctls.
When a namespace type is disabled, ns->ops is NULL, causes crashes
during inode eviction when closing the fd. The ifdefs were removed in
a recent simplification but are still needed
- Fixe a race where a folio could be unlocked before the trailing zeros

- Split out a dedicated lease_dispose_list() helper since lease code
paths always know they're disposing of leases. Removes unnecessary
runtime flag checks and prepares for upcoming lease_manager

- Fix userland delegation requests succeeding despite conflicting
opens. Previously, FL_LAYOUT and FL_DELEG leases bypassed conflict
checks (a hack for nfsd). Adds new ->lm_open_conflict() lease_manager

Pull tracing fixes from Steven Rostedt:
- Remove useless assignment of soft_mode variable
The function __ftrace_event_enable_disable() sets "soft_mode" in one
of the branch paths but doesn't use it after that. Remove the setting
of that variable.
- Add a cond_resched() in ring_buffer_resize()
The resize function that allocates all the pages for the ring buffer
was causing a soft lockup on PREEMPT_NONE configs when allocating
large buffers on machines with many CPUs. Hopefully this is the last
cond_resched() needed to be added as PREEMPT_LAZY becomes the norm in
the future.
- Make ftrace_graph_ent depth field signed
The "depth" field of struct ftrace_graph_ent was converted from "int"
to "unsigned long" for alignment reasons to work with being embedded
in other structures. The conversion from a signed to unsigned caused
integrity checks to always pass as they were comparing "depth" to
less than zero. Make the field signed long.
- Add recursion protection to stack trace events
A infinite recursion was triggered by a stack trace event calling RCU
which internally called rcu_read_unlock_special(), which triggered an
event that was also doing stacktraces which cause it to trigger the
same RCU lock that called rcu_read_unlock_special() again.
Update the trace_test_and_set_recursion() to add a set of context
checks for events to use, and have the stack trace event use that for
recursion protection.
- Make the variable ftrace_dump_on_oops static
The cleanup of sysctl that moved all the updates to the files that
use them moved the reference of ftrace_dump_on_oops to where it is
used. It is no longer used outside of the trace.c file. Make it

A bug was reported about an infinite recursion caused by tracing the rcu
events with the kernel stack trace trigger enabled. The stack trace code
called back into RCU which then called the stack trace again.
Expand the ftrace recursion protection to add a set of bits to protect
events from recursion. Each bit represents the context that the event is
in (normal, softirq, interrupt and NMI).
Have the stack trace code use the interrupt context to protect against
recursion.
Note, the bug showed an issue in both the RCU code as well as the tracing
stacktrace code. This only handles the tracing stack trace side of the
bug. The RCU fix will be handled separately.

The code has integrity checks to make sure that depth never goes below
zero. But the depth field has recently been converted to unsigned long
from "int" (for alignment reasons). As unsigned long can never be less

Convert depth to long from unsigned long to allow the integrity checks to

In ACPI Global System Interrupts (GSIs) are described using a 32-bit
value.
ACPI/PCI legacy interrupts (INTx) parsing code treats GSIs as 'int',
which poses issues if the GSI interrupt value is a 32-bit value with the
MSB set (as required in some interrupt configurations - eg ARM64 GICv5
systems) because acpi_pci_link_allocate_irq() treats a negative gsi
return value as a failed GSI allocation (and acpi_irq_get_penalty()
would trigger an out-of-bounds array dereference if the 'irq' param is
a negative value).
Fix ACPI/PCI legacy INTx parsing by converting variables representing
GSIs from 'int' to 'u32' bringing the code in line with the ACPI
specification and fixing the current parsing issue.

Directly increment the TSO features incurs a side effect: it will also
directly clear the flags in NETIF_F_ALL_FOR_ALL on the master device,
which can cause issues such as the inability to enable the nocache copy

The fix is to include NETIF_F_ALL_FOR_ALL in the update mask, thereby
preventing it from being cleared.

I haven't found an NFSERR_EAGAIN in RFCs 1094, 1813, 7530, or 8881.
None of these RFCs have an NFS status code that match the numeric
value "11".
Based on the meaning of the EAGAIN errno, I presume the use of this
status in NFSD means NFS4ERR_DELAY. So replace the one usage of
nfserr_eagain, and remove it from NFSD's NFS status conversion
tables.
As far as I can tell, NFSERR_EAGAIN has existed since the pre-git
era, but was not actually used by any code until commit f4e44b393389
("NFSD: delay unmount source's export after inter-server copy
completed."), at which time it become possible for NFSD to return
a status code of 11 (which is not valid NFS protocol).
Fixes: f4e44b393389 ("NFSD: delay unmount source's export after inter-server copy completed.")

</TASK>
Add a separate lock just for the tctx_list, tctx_lock. This can nest
under ->uring_lock, where necessary, and be used separately for list
manipulation. For the cancelation off exec side, this removes the
need to grab ->uring_lock, hence fixing the circular locking
dependency.

The first member of struct xattr_args is declared as
__aligned_u64 __user value;
which makes no sense whatsoever; __user is a qualifier and what that
declaration says is "all struct xattr_args instances have .value
_stored_ in user address space, no matter where the rest of the
structure happens to be".
Something like "int __user *p" stands for "value of p is a pointer
to an instance of int that happens to live in user address space"; it
says nothing about location of p itself, just as const char *p declares a
pointer to unmodifiable char rather than an unmodifiable pointer to char.
With xattr_args the intent clearly had been "the 64bit value
represents a _pointer_ to object in user address space", but __user has
nothing to do with that. All it gets us is a couple of bogus warnings
in fs/xattr.c where (userland) instance of xattr_args is copied to local
variable of that type (in kernel address space), followed by access
to its members. Since we've told sparse that args.value must somehow be
located in userland memory, we get warned that looking at that 64bit
unsigned integer (in a variable already on kernel stack) is not allowed.
Note that sparse has no way to express "this integer shall never
be cast into a pointer to be dereferenced directly" and I don't see any
way to assign a sane semantics to that. In any case, __user is not it.

Commit 2b938e3db335 ("vfio/pci: Enable iowrite64 and ioread64 for vfio
pci") enables qword access to the PCI bar resources. However certain
devices (e.g. Intel X710) are observed with problem upon qword accesses
to the rom bar, e.g. triggering PCI aer errors.
This is triggered by Qemu which caches the rom content by simply does a
pread() of the remaining size until it gets the full contents. The other
bars would only perform operations at the same access width as their
guest drivers.
Instead of trying to identify all broken devices, universally disable
qword access to the rom bar i.e. going back to the old way which worked
reliably for years.

Currently, folio_expected_ref_count() only adds references for the swap
cache if the folio is anonymous. However, according to the comment above
the definition of PG_swapcache in enum pageflags, shmem folios can also
have PG_swapcache set. This patch makes sure references for the swap
cache are added if folio_test_swapcache(folio) is true.
This issue was found when trying to hot-unplug memory in a QEMU/KVM
virtual machine. When initiating hot-unplug when most of the guest memory
is allocated, hot-unplug hangs partway through removal due to migration
failures. The following message would be printed several times, and would
be printed again about every five seconds:
[ 49.641309] migrating pfn b12f25 failed ret:7

[ 49.641315] page dumped because: migration failure
When debugging this, I found that these migration failures were due to
__migrate_folio() returning -EAGAIN for a small set of folios because the
expected reference count it calculates via folio_expected_ref_count() is
one less than the actual reference count of the folios. Furthermore, all
of the affected folios were not anonymous, but had the PG_swapcache flag
set, inspiring this patch. After applying this patch, the memory
hot-unplug behaves as expected.
I tested this on a machine running Ubuntu 24.04 with kernel version
6.8.0-90-generic and 64GB of memory. The guest VM is managed by libvirt
and runs Ubuntu 24.04 with kernel version 6.18 (though the head of the
mm-unstable branch as a Dec 16, 2025 was also tested and behaves the same)
and 48GB of memory. The libvirt XML definition for the VM can be found at
[1]. CONFIG_MHP_DEFAULT_ONLINE_TYPE_ONLINE_MOVABLE is set in the guest
kernel so the hot-pluggable memory is automatically onlined.
Below are the steps to reproduce this behavior:
1) Define and start and virtual machine
host$ virsh -c qemu:///system define ./test_vm.xml # test_vm.xml from [1]
host$ virsh -c qemu:///system start test_vm
2) Setup swap in the guest
guest$ sudo fallocate -l 32G /swapfile
guest$ sudo chmod 0600 /swapfile
guest$ sudo mkswap /swapfile
guest$ sudo swapon /swapfile
3) Use alloc_data [2] to allocate most of the remaining guest memory
guest$ ./alloc_data 45
4) In a separate guest terminal, monitor the amount of used memory
guest$ watch -n1 free -h
5) When alloc_data has finished allocating, initiate the memory
hot-unplug using the provided xml file [3]
host$ virsh -c qemu:///system detach-device test_vm ./remove.xml --live
After initiating the memory hot-unplug, you should see the amount of
available memory in the guest decrease, and the amount of used swap data
increase. If everything works as expected, when all of the memory is
unplugged, there should be around 8.5-9GB of data in swap. If the
unplugging is unsuccessful, the amount of used swap data will settle below
that. If that happens, you should be able to see log messages in dmesg
similar to the one posted above.

The memory failure handling implementation for the PFNMAP memory with no
struct pages is faulty. The VA of the mapping is determined based on the
the PFN. It should instead be based on the file mapping offset.
At the occurrence of poison, the memory_failure_pfn is triggered on the
poisoned PFN. Introduce a callback function that allows mm to translate
the PFN to the corresponding file page offset. The kernel module using
the registration API must implement the callback function and provide the
translation. The translated value is then used to determine the VA
information and sending the SIGBUS to the usermode process mapped to the
poisoned PFN.
The callback is also useful for the driver to be notified of the poisoned
PFN, which may then track it.

A KASAN tag mismatch, possibly causing a kernel panic, can be observed
on systems with a tag-based KASAN enabled and with multiple NUMA nodes.
It was reported on arm64 and reproduced on x86. It can be explained in
the following points:
1. There can be more than one virtual memory chunk.
2. Chunk's base address has a tag.
3. The base address points at the first chunk and thus inherits
the tag of the first chunk.
4. The subsequent chunks will be accessed with the tag from the
first chunk.
5. Thus, the subsequent chunks need to have their tag set to
match that of the first chunk.
Refactor code by reusing __kasan_unpoison_vmalloc in a new helper in
preparation for the actual fix.

Patch series "kasan: vmalloc: Fixes for the percpu allocator and
vrealloc", v3.
Patches fix two issues related to KASAN and vmalloc.
The first one, a KASAN tag mismatch, possibly resulting in a kernel panic,
can be observed on systems with a tag-based KASAN enabled and with
multiple NUMA nodes. Initially it was only noticed on x86 [1] but later a
similar issue was also reported on arm64 [2].
Specifically the problem is related to how vm_structs interact with
pcpu_chunks - both when they are allocated, assigned and when pcpu_chunk
addresses are derived.
When vm_structs are allocated they are unpoisoned, each with a different
random tag, if vmalloc support is enabled along the KASAN mode. Later
when first pcpu chunk is allocated it gets its 'base_addr' field set to
the first allocated vm_struct. With that it inherits that vm_struct's
tag.
When pcpu_chunk addresses are later derived (by pcpu_chunk_addr(), for
example in pcpu_alloc_noprof()) the base_addr field is used and offsets
are added to it. If the initial conditions are satisfied then some of the
offsets will point into memory allocated with a different vm_struct. So
while the lower bits will get accurately derived the tag bits in the top
of the pointer won't match the shadow memory contents.
The solution (proposed at v2 of the x86 KASAN series [3]) is to unpoison
the vm_structs with the same tag when allocating them for the per cpu
allocator (in pcpu_get_vm_areas()).
The second one reported by syzkaller [4] is related to vrealloc and
happens because of random tag generation when unpoisoning memory without
allocating new pages. This breaks shadow memory tracking and needs to
reuse the existing tag instead of generating a new one. At the same time
an inconsistency in used flags is corrected.
This patch (of 3):
Syzkaller reported a memory out-of-bounds bug [4]. This patch fixes two
issues:
1. In vrealloc the KASAN_VMALLOC_VM_ALLOC flag is missing when
unpoisoning the extended region. This flag is required to correctly
associate the allocation with KASAN's vmalloc tracking.
Note: In contrast, vzalloc (via __vmalloc_node_range_noprof)
explicitly sets KASAN_VMALLOC_VM_ALLOC and calls
kasan_unpoison_vmalloc() with it. vrealloc must behave consistently --
especially when reusing existing vmalloc regions -- to ensure KASAN can
track allocations correctly.
2. When vrealloc reuses an existing vmalloc region (without allocating
new pages) KASAN generates a new tag, which breaks tag-based memory
access tracking.
Introduce KASAN_VMALLOC_KEEP_TAG, a new KASAN flag that allows reusing the
tag already attached to the pointer, ensuring consistent tag behavior
during reallocation.
Pass KASAN_VMALLOC_KEEP_TAG and KASAN_VMALLOC_VM_ALLOC to the
kasan_unpoison_vmalloc inside vrealloc_node_align_noprof().
