commit 26b63bee2f6e711c5a169997fd126fddcfb90848 upstream.
In xfs_inactive(), xfs_reflink_cancel_cow_range() is called
without error handling, risking unnoticed failures and
inconsistent behavior compared to other parts of the code.
Fix this issue by adding an error handling for the

commit a5e6fc0a10fe280989f1367a3b4f8047c7d00ea6 upstream.
Access to safety cluster engine (SCE) fabric registers was blocked
by firewall after the introduction of Functional Safety Island in
Tegra234. After that, any access by software to SCE registers is
correctly resulting in the internal bus error. However, when CPUs
try accessing the SCE-fabric registers to print error info,
another firewall error occurs as the fabric registers are also
firewall protected. This results in a second error to be printed.
Disable the SCE fabric node to avoid printing the misleading error.
The first error info will be printed by the interrupt from the
fabric causing the actual access.

As QCE is an order of magnitude slower than the ARMv8 Crypto Extensions

Previously the QCE SHA algorithms had higher priority than the ARMv8 CE

meant the QCE versions were chosen if they happened to be loaded later.

-Wenum-enum-conversion was strengthened in clang-19 to warn for C, which
caused the kernel to move it to W=1 in commit 75b5ab134bb5 ("kbuild:
Move -Wenum-{compare-conditional,enum-conversion} into W=1") because
there were numerous instances that would break builds with -Werror.
Unfortunately, this is not a full solution, as more and more developers,
subsystems, and distributors are building with W=1 as well, so they
continue to see the numerous instances of this warning.
Since the move to W=1, there have not been many new instances that have
appeared through various build reports and the ones that have appeared
seem to be following similar existing patterns, suggesting that most
instances of this warning will not be real issues. The only alternatives
for silencing this warning are adding casts (which is generally seen as
an ugly practice) or refactoring the enums to macro defines or a unified
enum (which may be undesirable because of type safety in other parts of
the code).
Move the warning to W=2, where warnings that occur frequently but may be
relevant should reside.

If the SCSI command doesn't carry payload, the driver may use this value as

For interrupt-map entries, the DTS specification requires
that #address-cells is defined for both the child node and the
interrupt parent. For the PCIe interrupt-map entries, the parent
node ("gic") has not specified #address-cells. The existing layout
of the PCIe interrupt-map entries indicates that it assumes
that #address-cells is zero for this node.
Explicitly set #address-cells to zero for "gic" so that it complies
with the device tree specification.
NVIDIA EDK2 works around this issue by assuming #address-cells
is zero in this scenario, but that workaround is being removed and so
this update is needed or else NVIDIA EDK2 cannot successfully parse the
device tree and the board cannot boot.

blkdev_read_iter() has a few odd checks, like gating the position and
count adjustment on whether or not the result is bigger-than-or-equal to
zero (where bigger than makes more sense), and not checking the return
value of blkdev_direct_IO() before doing an iov_iter_revert(). The
latter can lead to attempting to revert with a negative value, which
when passed to iov_iter_revert() as an unsigned value will lead to
throwing a WARN_ON() because unroll is bigger than MAX_RW_COUNT.
Be sane and don't revert for -EIOCBQUEUED, like what is done in other

commit 42a39e4aa59a10aa4afdc14194f3ee63d2db94e1 upstream.
Currently, installation of Debian 12.8 for mipsel fails on machines
without an FPU [1]. This is caused by the fact that zstd (which is used
for initramfs compression) executes the prefx instruction, which is not
emulated properly by the kernel.
The prefx (Prefetch Indexed) instruction fetches data from memory into
the cache without any side effects. Though functionally unrelated, it
requires an FPU [2].
Bytecode format of this instruction ends on "001111" binary:
(prefx instruction format) & 0x0000003f = 0x0000000f
The code in fpux_emu() runs like so:
#define MIPSInst(x) x
#define MIPSInst_FMA_FFMT(x) (MIPSInst(x) & 0x00000007)
#define MIPSInst_FUNC(x) (MIPSInst(x) & 0x0000003f)
enum cop1x_func { ..., pfetch_op = 0x0f, ... };
...
switch (MIPSInst_FMA_FFMT(ir)) {
...
case 0x3:
if (MIPSInst_FUNC(ir) != pfetch_op)
return SIGILL;
/* ignore prefx operation */
break;
default:
return SIGILL;
}
That snippet above contains a logic error and the
if (MIPSInst_FUNC(ir) != pfetch_op)
comparison always fires.
When MIPSInst_FUNC(ir) is equal to pfetch_op, ir must end on 001111
binary. In this case, MIPSInst_FMA_FFMT(ir) must be equal to 0x7, which
does not match that case label.
This causes emulation failure for the prefx instruction. Fix it.
This has been broken by

commit 8b8f8037765757861f899ed3a2bfb34525b5c065 upstream.
dm-crypt uses tag_offset to index the integrity metadata for each crypt
sector. When the initial crypt_convert() returns BLK_STS_DEV_RESOURCE,
dm-crypt will try to continue the crypt/decrypt procedure in a kworker.
However, it resets tag_offset as zero instead of using the tag_offset
related with current sector. It may return unexpected data when using
random IV or return unexpected integrity related error.
Fix the problem by tracking tag_offset in per-IO convert_context.
Therefore, when the crypt/decrypt procedure continues in a kworker, it
could use the next tag_offset saved in convert_context.

The updates of io->sector are the leftovers when dm-crypt allocated

("dm crypt: don't allocate pages for a partial request"), there is no

After the introduction of write request rb-tree, the updates of
io->sectors may interfere the insertion procedure, because ->sectors of
these write requests which have already been added in the rb-tree may be
changed during the insertion of new write request.
Fix it by removing these buggy updates of io->sectors. Considering these
updates only effect the write request rb-tree, the commit which
introduces the write request rb-tree is used as the fix tag.

commit 11b93559000c686ad7e5ab0547e76f21cc143844 upstream.
The PE Reset State "0" returned by RTAS calls
"ibm_read_slot_reset_[state|state2]" indicates that the reset is
deactivated and the PE is in a state where MMIO and DMA are allowed.
However, the current implementation of "pseries_eeh_get_state()" does
not reflect this, causing drivers to incorrectly assume that MMIO and
DMA operations cannot be resumed.
The userspace drivers as a part of EEH recovery using VFIO ioctls fail
to detect when the recovery process is complete. The VFIO_EEH_PE_GET_STATE
ioctl does not report the expected EEH_PE_STATE_NORMAL state, preventing
userspace drivers from functioning properly on pseries systems.
The patch addresses this issue by updating 'pseries_eeh_get_state()'
to include "EEH_STATE_MMIO_ENABLED" and "EEH_STATE_DMA_ENABLED" in
the result mask for PE Reset State "0". This ensures correct state
reporting to the callers, aligning the behavior with the PAPR specification
and fixing the bug in EEH recovery for VFIO user workflows.

commit 22cf4fae6660b6e1a583a41cbf84e3046ca9ccd0 upstream.
On MSM8916 devices, the serial number exposed in sysfs is constant and does
not change across individual devices. It's always:
db410c:/sys/devices/soc0$ cat serial_number
2644893864
The firmware used on MSM8916 exposes SOCINFO_VERSION(0, 8), which does not
have support for the serial_num field in the socinfo struct. There is an
existing check to avoid exposing the serial number in that case, but it's
not correct: When checking the item_size returned by SMEM, we need to make
sure the *end* of the serial_num is within bounds, instead of comparing
with the *start* offset. The serial_number currently exposed on MSM8916
devices is just an out of bounds read of whatever comes after the socinfo
struct in SMEM.
Fix this by changing offsetof() to offsetofend(), so that the size of the
field is also taken into account.

commit 68abd0c4ebf24cd499841a488b97a6873d5efabb upstream.
On removal of the device or unloading of the kernel module a potential NULL
pointer dereference occurs.
The following sequence deletes the interface:
brcmf_detach()
brcmf_remove_interface()
brcmf_del_if()
Inside the brcmf_del_if() function the drvr->if2bss[ifidx] is updated to
BRCMF_BSSIDX_INVALID (-1) if the bsscfgidx matches.
After brcmf_remove_interface() call the brcmf_proto_detach() function is
called providing the following sequence:
brcmf_detach()
brcmf_proto_detach()
brcmf_proto_msgbuf_detach()
brcmf_flowring_detach()
brcmf_msgbuf_delete_flowring()
brcmf_msgbuf_remove_flowring()
brcmf_flowring_delete()
brcmf_get_ifp()
brcmf_txfinalize()
Since brcmf_get_ip() can and actually will return NULL in this case the
call to brcmf_txfinalize() will result in a NULL pointer dereference inside
brcmf_txfinalize() when trying to update ifp->ndev->stats.tx_errors.
This will only happen if a flowring still has an skb.
Although the NULL pointer dereference has only been seen when trying to
update the tx statistic, all other uses of the ifp pointer have been
guarded as well with an early return if ifp is NULL.

commit 8a5b38c3fd709e8acd2bfdedf66c25e6af759576 upstream.
The hid-sensor-hub creates the individual device structs and transfers them
to the created mfd platform-devices via the platform_data in the mfd_cell.
Before e651a1da44 ("HID: hid-sensor-hub: Allow parallel synchronous reads")
the sensor-hub was managing access centrally, with one "completion" in the
hub's data structure, which needed to be finished on removal at the latest.
The mentioned commit then moved this central management to each hid sensor
device, resulting on a completion in each struct hid_sensor_hub_device.
The remove procedure was adapted to go through all sensor devices and
finish any pending "completion".
What this didn't take into account was, platform_device_add_data() that is
used by mfd_add{_hotplug}_devices() does a kmemdup on the submitted
platform-data. So the data the platform-device gets is a copy of the
original data, meaning that the device worked on a different completion
than what sensor_hub_remove() currently wants to access.
To fix that, use device_for_each_child() to go through each child-device
similar to how mfd_remove_devices() unregisters the devices later and
with that get the live platform_data to finalize the correct completion.

'-std=' in the main Makefile. However, the EFI libstub Makefile uses its
own set of KBUILD_CFLAGS for x86 without a '-std=' value (i.e., using
the default), resulting in errors from the kernel's definitions of bool,
true, and false in stddef.h, which are reserved keywords under C23.
./include/linux/stddef.h:11:9: error: expected identifier before ‘false’
11 | false = 0,
./include/linux/types.h:35:33: error: two or more data types in declaration specifiers
35 | typedef _Bool bool;
Set '-std=gnu11' in the x86 cflags to resolve the error and consistently
use the same C standard version for the entire kernel. All other
architectures reuse KBUILD_CFLAGS from the rest of the kernel, so this
issue is not visible for them.

Add the parent_map property for the clock where it's missing and also
un-inline the parent_data as well to keep the matching parent_map and

commit 33f1722eb86e45320a3dd7b3d42f6593a1d595c2 upstream.
Commit c45ae598fc ("clk: qcom: support for alpha mode configuration")
added support for configuring alpha mode, but it seems that the feature
was never working in practice.
The value of the alpha_{en,mode}_mask members of the configuration gets
added to the value parameter passed to the regmap_update_bits() function,
however the same values are not getting applied to the bitmask. As the
result, the respective bits in the USER_CTL register are never modifed
which leads to improper configuration of several PLLs.
The following table shows the PLL configurations where the 'alpha_en_mask'
member is set and which are passed as a parameter for the
clk_alpha_pll_configure() function. In the table the 'expected rate' column
shows the rate the PLL should run at with the given configuration, and
the 'real rate' column shows the rate the PLL runs at actually. The real
rates has been verified on hardwareOn IPQ* platforms, on other platforms,
those are computed values only.

mmcc-sdm660.c mmpll8 930.0 MHz != 921.6 MHz
mmcc-sdm660.c mmpll5 825.0 MHz != 806.4 MHz
As it can be seen from the above, there are several PLLs which are
configured incorrectly.
Change the code to apply both 'alpha_en_mask' and 'alpha_mode_mask'
values to the bitmask in order to configure the alpha mode correctly.
Applying the 'alpha_en_mask' fixes the initial rate of the PLLs showed
in the table above. Since the 'alpha_mode_mask' is not used by any driver
currently, that part of the change causes no functional changes.

commit 5c61419e02033eaf01733d66e2fcd4044808f482 upstream.
One of the possible ways to enable the input MTU auto-selection for L2CAP
connections is supposed to be through passing a special "0" value for it
as a socket option. Commit [1] added one of those into avdtp. However, it
simply wouldn't work because the kernel still treats the specified value
as invalid and denies the setting attempt. Recorded BlueZ logs include the
following:

commit 5f397409f8ee5bc82901eeaf799e1cbc4f8edcf1 upstream.
A NULL sock pointer is passed into l2cap_sock_alloc() when it is called
from l2cap_sock_new_connection_cb() and the error handling paths should
also be aware of it.
Seemingly a more elegant solution would be to swap bt_sock_alloc() and
l2cap_chan_create() calls since they are not interdependent to that moment
but then l2cap_chan_create() adds the soon to be deallocated and still
dummy-initialized channel to the global list accessible by many L2CAP
paths. The channel would be removed from the list in short period of time
but be a bit more straight-forward here and just check for NULL instead of
changing the order of function calls.
Found by Linux Verification Center (linuxtesting.org) with SVACE static
analysis tool.

commit c7b49506b3ba7a62335e6f666a43f67d5cd9fd1e upstream.
I'm seeing underruns with these 64bpp YUV formats on TGL.
The weird details:
- only happens on pipe B/C/D SDR planes, pipe A SDR planes
seem fine, as do all HDR planes
- somehow CDCLK related, higher CDCLK allows for bigger plane
with these formats without underruns. With 300MHz CDCLK I
can only go up to 1200 pixels wide or so, with 650MHz even
a 3840 pixel wide plane was OK
- ICL and ADL so far appear unaffected
So not really sure what's the deal with this, but bspec does
state "64-bit formats supported only on the HDR planes" so
let's just drop these formats from the SDR planes. We already
disallow 64bpp RGB formats.
