Running "make kselftest TARGETS=intel_pstate" results in the
following errors:
- ./run.sh: line 89: cpupower: command not found
- ./run.sh: line 91: cpupower: command not found
if the cpupower is not installed.
Since the test depends on cpupower, this patch stops the test if the
cpupower is not installed.

Test case idmap_mount_tree_invalid failed to run on the newer kernel
with the following output:
# RUN mount_setattr_idmapped.idmap_mount_tree_invalid ...
# mount_setattr_test.c:1428:idmap_mount_tree_invalid:Expected sys_mount_setattr(open_tree_fd, "", AT_EMPTY_PATH, &attr, sizeof(attr)) (0) ! = 0 (0)
# idmap_mount_tree_invalid: Test terminated by assertion
This is because tmpfs is mounted at "/mnt/A", and tmpfs already
contains the flag FS_ALLOW_IDMAP after the commit 7a80e5b8c6fa ("shmem:
support idmapped mounts for tmpfs"). So calling sys_mount_setattr here
returns 0 instead of -EINVAL as expected.
Ramfs does not support idmap mounts, so we can use it here to test invalid mounts,
which allows the test case to pass with the following output:
# Starting 1 tests from 1 test cases.
# RUN mount_setattr_idmapped.idmap_mount_tree_invalid ...
# OK mount_setattr_idmapped.idmap_mount_tree_invalid
ok 1 mount_setattr_idmapped.idmap_mount_tree_invalid
# PASSED: 1 / 1 tests passed.

Read buffer is allocated according to max message size, reported by
the firmware and may reach 64K in systems with pxp client.
Contiguous 64k allocation may fail under memory pressure.
Read buffer is used as in-driver message storage and not required
to be contiguous.
Use kvmalloc to allow kernel to allocate non-contiguous memory.

The following race condition could trigger a NULL pointer dereference:
sock_map_link_detach(): sock_map_link_update_prog():
mutex_lock(&sockmap_mutex);
...
sockmap_link->map = NULL;
mutex_unlock(&sockmap_mutex);
mutex_lock(&sockmap_mutex);
...
sock_map_prog_link_lookup(sockmap_link->map);
mutex_unlock(&sockmap_mutex);
<continue>
Fix it by adding a NULL pointer check. In this specific case, it makes
no sense to update a link which is being released.

The widgets array in the snd_soc_dapm_widget_list has a __counted_by
attribute attached to it, which points to the num_widgets variable. This
attribute is used in bounds checking, and if it is not set before the
array is filled, then the bounds sanitizer will issue a warning or a
kernel panic if CONFIG_UBSAN_TRAP is set.
This patch sets the size of the widgets list calculated with
list_for_each as the initial value for num_widgets as it is used for
allocating memory for the array. It is updated with the actual number of
added elements after the array is filled.

KASAN reports the following UAF. The metadata_dst, which is used to
store the SCI value for macsec offload, is already freed by
metadata_dst_free() in macsec_free_netdev(), while driver still use it
for sending the packet.
To fix this issue, dst_release() is used instead to release
metadata_dst. So it is not freed instantly in macsec_free_netdev() if
still referenced by skb.

And some modifications in the MPTCP selftests:
- Patch 2: a small addition to the MPTCP selftests to cover more code.

Listing all the values linked to the MPTCP sysctl knobs was not
exercised in MPTCP test suite.
Let's do that to avoid any regressions, but also to have a kernel with a
debug kconfig verifying more assumptions. For the moment, we are not
interested by the output, only to avoid crashes and warnings.

Empirically we can confirm that the former allocates 152 bytes for the
table, while the latter memsets the 168 large block.
Root cause appears that when GPU metrics tables for v2_4 parts were added
it was not considered to enlarge the table to fit.
The fix in this patch is rather "brute force" and perhaps later should be
done in a smarter way, by extracting and consolidating the part version to
size logic to a common helper, instead of brute forcing the largest
possible allocation. Nevertheless, for now this works and fixes the out of

adhere to the queue limits, and it returns a positive value, turn that

André Almeida <andrealmeid@igalia.com> says:
This patchset 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, I opted to have 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.
For example, if /srv/games is a case-insensitive directory on the host,
then applications will expect /srv/games/Steam/Half-Life and
/srv/games/steam/half-life to be interchangeable; but if the
container framework is only sharing /srv/games/Steam/Half-Life and
/srv/games/Steam/Portal (and not the rest of /srv/games) with the
container, with /srv, /srv/games and /srv/games/Steam as part of the
container's tmpfs root, then making /srv/games a case-insensitive
directory inside the container would be necessary to meet that
expectation.
I send a patch for xfstests to enable the casefold test (generic/556) for
tmpfs.[1] The test succeed.
You can test this patchset using:
sudo mount -t tmpfs -o casefold tmpfs mnt/
And making a dir case-insensitive:
mkdir mnt/dir
chattr +F mnt/dir

Enable casefold lookup in tmpfs, based on the encoding defined by
userspace. That means that instead of comparing byte per byte a file
name, it compares to a case-insensitive equivalent of the Unicode
string.
* Dcache handling
There's a special need when dealing with case-insensitive dentries.
First of all, we currently invalidated every negative casefold dentries.
That happens because currently VFS code has no proper support to deal
with that, giving that it could incorrectly reuse a previous filename
for a new file that has a casefold match. For instance, this could
happen:
$ mkdir DIR
$ rm -r DIR
$ mkdir dir
$ ls
DIR/
And would be perceived as inconsistency from userspace point of view,
because even that we match files in a case-insensitive manner, we still
honor whatever is the initial filename.
Along with that, tmpfs stores only the first equivalent name dentry used
in the dcache, preventing duplications of dentries in the dcache. The
d_compare() version for casefold files uses a normalized string, so the
filename under lookup will be compared to another normalized string for
the existing file, achieving a casefolded lookup.
* Enabling casefold via mount options
Most filesystems have their data stored in disk, so casefold option need
to be enabled when building a filesystem on a device (via mkfs).
However, as tmpfs is a RAM backed filesystem, there's no disk
information and thus no mkfs to store information about casefold.
For tmpfs, create casefold options for mounting. Userspace can then
enable casefold support for a mount point using:
$ mount -t tmpfs -o casefold=utf8-12.1.0 fs_name mount_dir/
Userspace must set what Unicode standard is aiming to. The available
options depends on what the kernel Unicode subsystem supports.
And for strict encoding:
$ mount -t tmpfs -o casefold=utf8-12.1.0,strict_encoding fs_name mount_dir/
Strict encoding means that tmpfs will refuse to create invalid UTF-8
sequences. When this option is not enabled, any invalid sequence will be
treated as an opaque byte sequence, ignoring the encoding thus not being
able to be looked up in a case-insensitive way.
* Check for casefold dirs on simple_lookup()
On simple_lookup(), do not create dentries for casefold directories.
Currently, VFS does not support case-insensitive negative dentries and
can create inconsistencies in the filesystem. Prevent such dentries to
being created in the first place.

All filesystems that currently support UTF-8 casefold can fetch the
UTF-8 version from the filesystem metadata stored on disk. They can get
the data stored and directly match it to a integer, so they can skip the
string parsing step, which motivated the removal of this function in the
first place.
However, for tmpfs, the only way to tell the kernel which UTF-8 version
we are about to use is via mount options, using a string. Re-introduce
utf8_parse_version() to be used by tmpfs.
This version differs from the original by skipping the intermediate step
of copying the version string to an auxiliary string before calling
match_token(). This versions calls match_token() in the argument string.
The paramenters are simpler now as well.
utf8_parse_version() was created by 9d53690f0d4 ("unicode: implement
higher level API for string handling") and later removed by 49bd03cc7e9
("unicode: pass a UNICODE_AGE() tripple to utf8_load").

and convert all callers to pass a folio directly except f2fs.
Convert the page to folio for all the callers from f2fs as they were the
only callers calling wbc_account_cgroup_owner() with a page. As f2fs is
already in the process of converting to folios, these call sites might
also soon be calling wbc_account_cgroup_owner() with a folio directly in
the future.
No functional changes. Only compile tested.

If devm_gpiod_get_optional() fails, we need to disable previously enabled
regulators, as done in the other error handling path of the function.
Also, gpiod_set_value_cansleep(, 1) needs to be called to undo a
potential gpiod_set_value_cansleep(, 0).
If the "reset" gpio is not defined, this additional call is just a no-op.
This behavior is the same as the one already in the .remove() function.

I was so sure the per-dentry expire timeout patch worked ok but my
testing was flawed.
In validate_dev_ioctl() the check for ioctl AUTOFS_DEV_IOCTL_TIMEOUT_CMD
should use the ioctl number not the passed in ioctl command.

When starting the SD Express process, the low power negotiation mode will
be disabled, so we need to re-enable it after switching back to SD mode.

On sdhci_gl9767_set_clock(), the vendor header space(VHS) is read-only
after calling gl9767_disable_ssc_pll() and gl9767_set_ssc_pll_205mhz().
So the low power negotiation mode cannot be enabled again.
Introduce gl9767_set_low_power_negotiation() function to fix it.
The explanation process is as below.
static void sdhci_gl9767_set_clock()
{
...
gl9767_vhs_write();
...
value |= PCIE_GLI_9767_CFG_LOW_PWR_OFF;
pci_write_config_dword(pdev, PCIE_GLI_9767_CFG, value); <--- (a)
gl9767_disable_ssc_pll(); <--- (b)
sdhci_writew(host, 0, SDHCI_CLOCK_CONTROL);
if (clock == 0)
return; <-- (I)
...
if (clock == 200000000 && ios->timing == MMC_TIMING_UHS_SDR104) {
...
gl9767_set_ssc_pll_205mhz(); <--- (c)
}
...
value &= ~PCIE_GLI_9767_CFG_LOW_PWR_OFF;
pci_write_config_dword(pdev, PCIE_GLI_9767_CFG, value); <-- (II)
gl9767_vhs_read();
}
(a) disable low power negotiation mode. When return on (I), the low power
mode is disabled. After (b) and (c), VHS is read-only, the low power mode
cannot be enabled on (II).

The maximum number of buffers that can be requested was increased to
64 for the video capture queue. But video capture used a must_blank
array that was still sized for 32 (VIDEO_MAX_FRAME). This caused an
out-of-bounds write when using buffer indices >= 32.
Create a new define MAX_VID_CAP_BUFFERS that is used to access the
must_blank array and set max_num_buffers for the video capture queue.
This solves a crash reported by:
