Merge tag 'fsnotify_for_v6.6-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs

Pull fanotify fix from Jan Kara:
 "Disable superblock / mount marks for filesystems that can encode file
  handles but not open them (currently only overlayfs).

  It is not clear the functionality is useful in any way so let's better
  disable it before someone comes up with some creative misuse"

845e31e110 seq_buf: fix a misleading comment
The comment for seq_buf_has_overflowed() says that an overflow condition is
marked by len == size, but that's not what the code is testing.  Make the
comment match reality.

f617647154 In the raw NAND subsystem, the major fix prevents using cached reads
with devices not supporting it. There was two bug reports about
 this. Aside, 3 drivers (pl353, arasan and marvell) could sometimes hide
 page program failures due to their their own program page helper not
 being fully compliant with the specification (many drivers use the
 default helpers shared by the core). Adding a missing check prevents
 these situation. Finally, the Qualcomm driver had a broken error path.
 
 In the SPI-NAND subsystem one Micron device used a wrong bitmak
 reporting possibly corrupted ECC status.
 
 Finally, the physmap-core got stripped from its map_rom fallback by
 mistake, this feature is added back.

b141fa036c drm/amd/display: Reduce stack size by splitting function
When compiling with allmodconfig, gcc highlights the following error:

drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c: In function 'dml_core_mode_support':
drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c:8229:1: error: the frame size of 2736 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
 8229 | } // dml_core_mode_support
      | ^
cc1: all warnings being treated as errors

This commit mitigates part of this problem by extracting the prefetch
code to its own function. After applying this commit, the stack size
reduces from 2736 to 2464, however, the stack size issue becomes part of
the new function.

68a8f64457 ima: Add __counted_by for struct modsig and use struct_size()
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

Also, relocate `hdr->raw_pkcs7_len = sig_len;` so that the __counted_by
annotation has effect, and flex-array member `raw_pkcs7` can be properly
bounds-checked at run-time.

While there, use struct_size() helper, instead of the open-coded
version, to calculate the size for the allocation of the whole
flexible structure, including of course, the flexible-array member.

This code was found with the help of Coccinelle, and audited and
fixed manually.

934bf871f0 KVM: arm64: Load the stage-2 MMU context in kvm_vcpu_load_vhe()
To date the VHE code has aggressively reloaded the stage-2 MMU context
on every guest entry, despite the fact that this isn't necessary. This
was probably done for consistency with the nVHE code, which needs to
switch in/out the stage-2 MMU context as both the host and guest run at
EL1.

Hoist __load_stage2() into kvm_vcpu_load_vhe(), thus avoiding a reload
on every guest entry/exit. This is likely to be beneficial to systems
with one of the speculative AT errata, as there is now one fewer context
synchronization event on the guest entry path. Additionally, it is
possible that implementations have hitched correctness mitigations on
writes to VTTBR_EL2, which are now elided on guest re-entry.

Note that __tlb_switch_to_guest() is deliberately left untouched as it
can be called outside the context of a running vCPU.

An MMU notifier could cause us to clobber the stage-2 context loaded on
a CPU when we switch to another VM's context to invalidate. This isn't
an issue right now as the stage-2 context gets reloaded on every guest
entry, but is disastrous when moving __load_stage2() into the
vcpu_load() path.

Restore the previous stage-2 context on the way out of a TLB
invalidation if we installed something else. Deliberately do this after
TGE=1 is synchronized to keep things safe in light of the speculative AT

50cbdaf1b9 PNP: replace deprecated strncpy() with memcpy()
strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous
interfaces.

After having precisely calculated the lengths and ensuring we don't
overflow the buffer, this really decays to just a memcpy. Let's not use
a C string api as it makes the intention of the code confusing.

It'd be nice to use strscpy() in this case (as we clearly want
NUL-termination) because it'd clean up the code a bit. However, I don't
quite know enough about what is going on here to justify a drop-in
replacement -- too much bit magic and why (PNP_NAME_LEN - 2)? I'm afraid
using strscpy() may result in copying too many or too few bytes into our
dev->name buffer resulting in different behavior. At least using
memcpy() we can ensure the behavior is exactly the same.

Side note:
NUL-padding is not required because insert_device() calls
pnpbios_parse_data_stream() with a zero-allocated `dev`:
299 |  static int __init insert_device(struct pnp_bios_node *node) {
...
312 |  dev = pnp_alloc_dev(&pnpbios_protocol, node->handle, id);
...
316 |  pnpbios_parse_data_stream(dev, node);

then pnpbios_parse_data_stream() calls pnpbios_parse_compatible_ids().

eda1a74655 PNP: ACPI: replace deprecated strncpy() with strscpy()
strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.

We know dev->name should be NUL-terminated based on the presence of a
manual NUL-byte assignment.

NUL-padding is not required as dev is already zero-allocated which
renders any further NUL-byte assignments redundant:
dev = pnp_alloc_dev(&pnpacpi_protocol, num, pnpid); --->
  dev = kzalloc(sizeof(struct pnp_dev), GFP_KERNEL);

Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding. This simplifies the code and makes
the intent/behavior more obvious.
