commit 4c92670b16727365699fe4b19ed32013bab2c107 upstream.
Setup function uvc_function_setup permits control transfer
requests with up to 64 bytes of payload (UVC_MAX_REQUEST_SIZE),
data stage handler for OUT transfer uses memcpy to copy req->actual
bytes to uvc_event->data.data array of size 60. This may result
in an overflow of 4 bytes.

commit 1f3868f06855c97a4954c99b36f3fc9eb8f60326 upstream.
When extending file within last block it can happen that the extent is
already rounded to the blocksize and thus contains the offset we want to
grow up to. In such case we would mistakenly expand the last extent and
make it one block longer than it should be, exposing unallocated block
in a file and causing data corruption. Fix the problem by properly
detecting this case and bailing out.

commit 16d0556568148bdcaa45d077cac9f8f7077cf70a upstream.
When extending file with a hole, we tried to preserve existing
preallocation for the file. However that is not very useful and
complicates code because the previous extent may need to be rounded to
block boundary as well (which we forgot to do thus causing data
corruption for sequence like:
xfs_io -f -c "pwrite 0x75e63 11008" -c "truncate 0x7b24b" \
-c "truncate 0xabaa3" -c "pwrite 0xac70b 22954" \
-c "pwrite 0x93a43 11358" -c "pwrite 0xb8e65 52211" file
with 512-byte block size. Just discard preallocation before extending
file to simplify things and also fix this data corruption.

ARM: 9278/1: kfence: only handle translation faults
memcg_write_event_control() accesses the dentry->d_name of the specified
control fd to route the write call. As a cgroup interface file can't be
renamed, it's safe to access d_name as long as the specified file is a
regular cgroup file. Also, as these cgroup interface files can't be
removed before the directory, it's safe to access the parent too.
Prior to 347c4a8747 ("memcg: remove cgroup_event->cft"), there was a
call to __file_cft() which verified that the specified file is a regular
cgroupfs file before further accesses. The cftype pointer returned from
__file_cft() was no longer necessary and the commit inadvertently dropped
the file type check with it allowing any file to slip through. With the
invarients broken, the d_name and parent accesses can now race against
renames and removals of arbitrary files and cause use-after-free's.
Fix the bug by resurrecting the file type check in __file_cft(). Now that
cgroupfs is implemented through kernfs, checking the file operations needs
to go through a layer of indirection. Instead, let's check the superblock
and dentry type.

Add more sanity checks to the VMA that do_brk_flags() will expand. Ensure
the VMA matches basic merge requirements within the function before
calling can_vma_merge_after().
Drop the duplicate checks from vm_brk_flags() since they will be enforced
later.
The old code would expand file VMAs on brk(), which is functionally
wrong and also dangerous in terms of locking because the brk() path
isn't designed for file VMAs and therefore doesn't lock the file
mapping. Checking can_vma_merge_after() ensures that new anonymous
VMAs can't be merged into file VMAs.

We use "unsigned long" to store a PFN in the kernel and phys_addr_t to
store a physical address.
On a 64bit system, both are 64bit wide. However, on a 32bit system, the
latter might be 64bit wide. This is, for example, the case on x86 with
PAE: phys_addr_t and PTEs are 64bit wide, while "unsigned long" only spans
32bit.
The current definition of SWP_PFN_BITS without MAX_PHYSMEM_BITS misses
that case, and assumes that the maximum PFN is limited by an 32bit
phys_addr_t. This implies, that SWP_PFN_BITS will currently only be able
to cover 4 GiB - 1 on any 32bit system with 4k page size, which is wrong.
Let's rely on the number of bits in phys_addr_t instead, but make sure to
not exceed the maximum swap offset, to not make the BUILD_BUG_ON() in
is_pfn_swap_entry() unhappy. Note that swp_entry_t is effectively an
unsigned long and the maximum swap offset shares that value with the swap
type.
For example, on an 8 GiB x86 PAE system with a kernel config based on
Debian 11.5 (-> CONFIG_FLATMEM=y, CONFIG_X86_PAE=y), we will currently
fail removing migration entries (remove_migration_ptes()), because
mm/page_vma_mapped.c:check_pte() will fail to identify a PFN match as
swp_offset_pfn() wrongly masks off PFN bits. For example,
split_huge_page_to_list()->...->remap_page() will leave migration entries
in place and continue to unlock the page.
Later, when we stumble over these migration entries (e.g., via
/proc/self/pagemap), pfn_swap_entry_to_page() will BUG_ON() because these
migration entries shouldn't exist anymore and the page was unlocked.

Fix tmpfs data loss when the fallocate system call is interrupted by a
signal, or fails for some other reason. The partial folio handling in
shmem_undo_range() forgot to consider this unfalloc case, and was liable
to erase or truncate out data which had already been committed earlier.
It turns out that none of the partial folio handling there is appropriate
for the unfalloc case, which just wants to proceed to removal of whole
folios: which find_get_entries() provides, even when partially covered.

This reverts commit 532223c8ac.
As reported in [0], hid-logitech-hidpp now binds on all bluetooth mice,
but there are corner cases where hid-logitech-hidpp just gives up on
the mouse. This leads the end user with a dead mouse.
Given that we are at -rc8, we are definitively too late to find a proper
fix. We already identified 2 issues less than 24 hours after the bug
report. One in that ->match() was never designed to be used anywhere else
than in hid-generic, and the other that hid-logitech-hidpp has corner
cases where it gives up on devices it is not supposed to.
So we have no choice but postpone this patch to the next kernel release.

This reverts commit 8544c812e4.
We need to revert commit 532223c8ac ("HID: logitech-hidpp: Enable HID++
for all the Logitech Bluetooth devices") because that commit might make
hid-logitech-hidpp bind on mice that are not well enough supported by
hid-logitech-hidpp, and the end result is that the probe of those mice
is now returning -ENODEV, leaving the end user with a dead mouse.
Given that commit 8544c812e4 ("HID: logitech-hidpp: Remove special-casing
of Bluetooth devices") is a direct dependency of 532223c8ac, revert it
too.
Note that this also adapt according to commit 908d325e16 ("HID:
logitech-hidpp: Detect hi-res scrolling support") to re-add support of
the devices that were removed from that commit too.
I have locally an MX Master and I tested this device with that revert,
ensuring we still have high-res scrolling.

memcg_write_event_control() accesses the dentry->d_name of the specified
control fd to route the write call. As a cgroup interface file can't be
renamed, it's safe to access d_name as long as the specified file is a
regular cgroup file. Also, as these cgroup interface files can't be
removed before the directory, it's safe to access the parent too.
Prior to 347c4a8747 ("memcg: remove cgroup_event->cft"), there was a
call to __file_cft() which verified that the specified file is a regular
cgroupfs file before further accesses. The cftype pointer returned from
__file_cft() was no longer necessary and the commit inadvertently
dropped the file type check with it allowing any file to slip through.
With the invarients broken, the d_name and parent accesses can now race
against renames and removals of arbitrary files and cause
use-after-free's.
Fix the bug by resurrecting the file type check in __file_cft(). Now
that cgroupfs is implemented through kernfs, checking the file
operations needs to go through a layer of indirection. Instead, let's
check the superblock and dentry type.

The SJA1105 family has 45 L2 policing table entries
(SJA1105_MAX_L2_POLICING_COUNT) and SJA1110 has 110
(SJA1110_MAX_L2_POLICING_COUNT). Keeping the table structure but
accounting for the difference in port count (5 in SJA1105 vs 10 in
SJA1110) does not fully explain the difference. Rather, the SJA1110 also
has L2 ingress policers for multicast traffic. If a packet is classified
as multicast, it will be processed by the policer index 99 + SRCPORT.
The sja1105_init_l2_policing() function initializes all L2 policers such
that they don't interfere with normal packet reception by default. To have
a common code between SJA1105 and SJA1110, the index of the multicast
policer for the port is calculated because it's an index that is out of
bounds for SJA1105 but in bounds for SJA1110, and a bounds check is
performed.
The code fails to do the proper thing when determining what to do with the
multicast policer of port 0 on SJA1105 (ds->num_ports = 5). The "mcast"
index will be equal to 45, which is also equal to
table->ops->max_entry_count (SJA1105_MAX_L2_POLICING_COUNT). So it passes
through the check. But at the same time, SJA1105 doesn't have multicast
policers. So the code programs the SHARINDX field of an out-of-bounds
element in the L2 Policing table of the static config.
The comparison between index 45 and 45 entries should have determined the
code to not access this policer index on SJA1105, since its memory wasn't
even allocated.
With enough bad luck, the out-of-bounds write could even overwrite other
valid kernel data, but in this case, the issue was detected using KASAN.

In an earlier commit, I added a bounds check to prevent an out of bounds
read and a WARN(). On further discussion and consideration that check
was probably too aggressive. Instead of returning -EINVAL, a better fix
would be to just prevent the out of bounds read but continue the process.
Background: The value of "pp->rxq_def" is a number between 0-7 by default,
or even higher depending on the value of "rxq_number", which is a module
parameter. If the value is more than the number of available CPUs then
it will trigger the WARN() in cpu_max_bits_warn().

It introduced a boot regression on colibri-imx7, and potentially any

U-Boot.
While the commit we are reverting here is not obviously wrong, it fixes
only a dt binding checker warning that is non-functional, while it
introduces a boot regression and there is no obvious fix ready.
