Prevent a potential invalid memory access when the requested sensor
is not found.
find_ec_sensor_index() may return a negative value (e.g. -ENOENT),
but its result was used without checking, which could lead to
undefined behavior when passed to get_sensor_info().
Add a proper check to return -EINVAL if sensor_index is negative.

If ctx->steps is zero, the loop processing ECC steps is skipped,
and the variable ret remains uninitialized. It is later checked
and returned, which leads to undefined behavior and may cause
unpredictable results in user space or kernel crashes.
This scenario can be triggered in edge cases such as misconfigured
geometry, ECC engine misuse, or if ctx->steps is not validated
after initialization.
Initialize ret to zero before the loop to ensure correct and safe
behavior regardless of the ctx->steps value.

__bind was changing the disk capacity, geometry and mempools of the

fail, forcing dm to drop the new table. Failing here would leave the

Move dm_table_set_restrictions() earlier in __bind(). Since it needs the

This doesn't happen when we use ESC or the Left arrow key to Zoom out of
a specific thread, making this operation not to work and we get stuck
into the thread zoom.
In 6422184b08 ("perf hists browser: Simplify zooming code using
pstack_peek()") it says no need to set actions->thread, and at that
point that was true, but in 7cecb7fe83 a actions->thread == NULL

We can zoom out using the alternative 't' thread zoom toggle hotkey to
finally set actions->thread before calling do_zoom_thread() and zoom
out, but lets also fix the ESC/Zoom out of thread case.

[ Upstream commit e136a4062174a9a8d1c1447ca040ea81accfa6a8 ]
When building the randomized replacement tree of struct members, the
randstruct GCC plugin would insert, as the first member, a 0-sized void
member. This appears as though it was done to catch non-designated
("unnamed") static initializers, which wouldn't be stable since they
depend on the original struct layout order.
This was accomplished by having the side-effect of the "void member"
tripping an assert in GCC internals (count_type_elements) if the member
list ever needed to be counted (e.g. for figuring out the order of members
during a non-designated initialization), which would catch impossible type
(void) in the struct:
security/landlock/fs.c: In function ‘hook_file_ioctl_common’:
security/landlock/fs.c:1745:61: internal compiler error: in count_type_elements, at expr.cc:7075
1745 | .u.op = &(struct lsm_ioctlop_audit) {
| ^
static HOST_WIDE_INT
count_type_elements (const_tree type, bool for_ctor_p)
{
switch (TREE_CODE (type))
...
case VOID_TYPE:
default:
gcc_unreachable ();
}
}
However this is a redundant safety measure since randstruct uses the
__designated_initializer attribute both internally and within the
__randomized_layout attribute macro so that this would be enforced
by the compiler directly even when randstruct was not enabled (via
-Wdesignated-init).
A recent change in Landlock ended up tripping the same member counting
routine when using a full-struct copy initializer as part of an anonymous
initializer. This, however, is a false positive as the initializer is
copying between identical structs (and hence identical layouts). The
"path" member is "struct path", a randomized struct, and is being copied
to from another "struct path", the "f_path" member:
landlock_log_denial(landlock_cred(file->f_cred), &(struct landlock_request) {
.type = LANDLOCK_REQUEST_FS_ACCESS,
.audit = {
.type = LSM_AUDIT_DATA_IOCTL_OP,
.u.op = &(struct lsm_ioctlop_audit) {
.path = file->f_path,
.cmd = cmd,
},
},
...
As can be seen with the coming randstruct KUnit test, there appears to
be no behavioral problems with this kind of initialization when the void
member is removed from the randstruct GCC plugin, so remove it.

The u2phy0_host port is the part of the USB PHY0 (namely the
HOST0_DP/DM lanes) which routes directly to the USB2.0 HOST
controller[1]. The other lanes of the PHY are routed to the USB3.0 OTG
controller (dwc3), which we do use.
The HOST0_DP/DM lanes aren't routed on RK3399 Puma so let's simply
disable the USB2.0 controllers.
USB3 OTG has been known to be unstable on RK3399 Puma Haikou for a
while, one of the recurring issues being that only USB2 is detected and
not USB3 in host mode. Reading the justification above and seeing that
we are keeping u2phy0_host in the Haikou carrierboard DTS probably may
have bothered you since it should be changed to u2phy0_otg. The issue is
that if it's switched to that, USB OTG on Haikou is entirely broken. I
have checked the routing in the Gerber file, the lanes are going to the
expected ball pins (that is, NOT HOST0_DP/DM).
u2phy0_host is for sure the wrong part of the PHY to use, but it's the
only one that works at the moment for that board so keep it until we
figure out what exactly is broken.
No intended functional change.

If the pointer value obtained by nilfs_direct_get_ptr() is
NILFS_BMAP_INVALID_PTR, means that the metadata (in this case, i_bmap in

meaning that the file system has lost consistency.
Add a value check and return -EINVAL when it is an invalid pointer.

Syzkaller reports an "UBSAN: shift-out-of-bounds in squashfs_bio_read" bug.
Syzkaller forks multiple processes which after mounting the Squashfs
filesystem, issues an ioctl("/dev/loop0", LOOP_SET_BLOCK_SIZE, 0x8000).
Now if this ioctl occurs at the same time another process is in the
process of mounting a Squashfs filesystem on /dev/loop0, the failure
occurs. When this happens the following code in squashfs_fill_super()
fails.
----
msblk->devblksize = sb_min_blocksize(sb, SQUASHFS_DEVBLK_SIZE);
msblk->devblksize_log2 = ffz(~msblk->devblksize);
----
sb_min_blocksize() returns 0, which means msblk->devblksize is set to 0.
As a result, ffz(~msblk->devblksize) returns 64, and msblk->devblksize_log2
is set to 64.
This subsequently causes the
UBSAN: shift-out-of-bounds in fs/squashfs/block.c:195:36
shift exponent 64 is too large for 64-bit type 'u64' (aka
'unsigned long long')

[ Upstream commit 8c716f80dfe8cd6ed9a2696847cea1affeeff6ff ]
The HDMI bridge chip fails to generate an audio source due to the SAI5
master clock (MCLK) direction not being set to output. This prevents proper
clocking of the HDMI audio interface.
Add the `fsl,sai-mclk-direction-output` property to the SAI5 node to ensure
the MCLK is driven by the SoC, resolving the HDMI sound issue.

Although not noticeable when used every day, the RTC appears to drift when
left to sit over time. This is due to the capacitive load not being
properly set. Fix RTC drift by correcting the capacitive load setting
from 7000 to 12500, which matches the actual hardware configuration.

[ Upstream commit 394f29033324e2317bfd6a7ed99b9a60832b36a2 ]
By hardware, the first and second core of the video decoder IP
need the VDEC_SOC to be powered up in order to be able to be
accessed (both internally, by firmware, and externally, by the
kernel).
Similarly, for the video encoder IP, the second core needs the
first core to be powered up in order to be accessible.
Fix that by reparenting the VDEC1/2 power domains to be children
of VDEC0 (VDEC_SOC), and the VENC1 to be a child of VENC0.

[ Upstream commit a2e617f4e6981aa514a569e927f90b0d39bb31b2 ]
The WCD938x codec provides two controls for each of the MIC_BIASn outputs:
- "MIC BIASn" enables an internal regulator to generate the output
with a configurable voltage (qcom,micbiasN-microvolt).
- "VA MIC BIASn" enables "pull-up mode" that bypasses the internal
regulator and directly outputs fixed 1.8V from the VDD_PX pin.
This is intended for low-power VA (voice activation) use cases.
The audio-routing setup for the ThinkPad X13s currently specifies both
as power supplies for the DMICs, but only one of them can be active
at the same time. In practice, only the internal regulator is used
with the current setup because the driver prefers it over pull-up mode.
Make this more clear by dropping the redundant routes to the pull-up
"VA MIC BIASn" supply. There is no functional difference except that we
skip briefly switching to pull-up mode when shutting down the microphone.

When num-channels and qcom,num-ees is not provided in devicetree, the
driver will try to read these values from the registers during probe but
this fails if the interconnect is not on and then crashes the system.
So we can provide these properties in devicetree (queried after patching
BAM driver to enable the necessary interconnect) so we can probe
cryptobam without reading registers and then also use the QCE as
expected.
