commit ecfe9a015d3e1e46504d5b3de7eef1f2d186194a upstream.
pinctrl_register_one_pin() doesn't check the result of radix_tree_insert()
despite they both may return a negative error code. Linus Walleij said he
has copied the radix tree code from kernel/irq/ where the functions calling
radix_tree_insert() are *void* themselves; I think it makes more sense to
propagate the errors from radix_tree_insert() upstream if we can do that...

commit 130afc8a886183a94cf6eab7d24f300014ff87ba upstream.
When slice_height is 0, the division by slice_height in the calculation
of the number of slices will cause a division by zero driver crash. This
leaves the kernel in a state that requires a reboot. This patch adds a
check to avoid the division by zero.
The stack trace below is for the 6.8.4 Kernel. I reproduced the issue on
a Z16 Gen 2 Lenovo Thinkpad with a Apple Studio Display monitor
connected via Thunderbolt. The amdgpu driver crashed with this exception
when I rebooted the system with the monitor connected.

After applying this patch, the driver no longer crashes when the monitor
is connected and the system is rebooted. I believe this is the same
issue reported for 3113.

commit 9da27fb65a14c18efd4473e2e82b76b53ba60252 upstream.
The expiry time of a key is unconditionally overwritten during
instantiation, defaulting to turn it permanent. This causes a problem
for DNS resolution as the expiration set by user-space is overwritten to
TIME64_MAX, disabling further DNS updates. Fix this by restoring the
condition that key_set_expiry is only called when the pre-parser sets a
specific expiry.

commit a112d3c72a227f2edbb6d8094472cc6e503e52af upstream.
The NVM configuration files used by WCN3988 and WCN3990/1/8 have two
sets of configuration tags that are enclosed by a type-length header of
type four which the current parser fails to account for.
Instead the driver happily parses random data as if it were valid tags,
something which can lead to the configuration data being corrupted if it
ever encounters the words 0x0011 or 0x001b.
As is clear from commit b63882549b2b ("Bluetooth: btqca: Fix the NVM
baudrate tag offcet for wcn3991") the intention has always been to
process the configuration data also for WCN3991 and WCN3998 which
encodes the baud rate at a different offset.
Fix the parser so that it can handle the WCN3xxx configuration files,
which has an enclosing type-length header of type four and two sets of
TLV tags enclosed by a type-length header of type two and three,
respectively.
Note that only the first set, which contains the tags the driver is
currently looking for, will be parsed for now.
With the parser fixed, the software in-band sleep bit will now be set
for WCN3991 and WCN3998 (as it is for later controllers) and the default
baud rate 3200000 may be updated by the driver also for WCN3xxx
controllers.
Notably the deep-sleep feature bit is already set by default in all
configuration files in linux-firmware.

commit a26ff37e624d12e28077e5b24d2b264f62764ad6 upstream.
net_alloc_generic is called by net_alloc, which is called without any
locking. It reads max_gen_ptrs, which is changed under pernet_ops_rwsem. It
is read twice, first to allocate an array, then to set s.len, which is
later used to limit the bounds of the array access.
It is possible that the array is allocated and another thread is
registering a new pernet ops, increments max_gen_ptrs, which is then used
to set s.len with a larger than allocated length for the variable array.
Fix it by reading max_gen_ptrs only once in net_alloc_generic. If
max_gen_ptrs is later incremented, it will be caught in net_assign_generic.

commit d18ca8635db2f88c17acbdf6412f26d4f6aff414 upstream.
When using davinci-mcasp as CPU DAI with simple-card, there are some
conditions that cause simple-card to finish registering a sound card before
davinci-mcasp finishes registering all sound components. This creates a
non-working sound card from userspace with no problem indication apart
from not being able to play/record audio on a PCM stream. The issue
arises during simultaneous probe execution of both drivers. Specifically,
the simple-card driver, awaiting a CPU DAI, proceeds as soon as
davinci-mcasp registers its DAI. However, this process can lead to the
client mutex lock (client_mutex in soc-core.c) being held or davinci-mcasp
being preempted before PCM DMA registration on davinci-mcasp finishes.
This situation occurs when the probes of both drivers run concurrently.
Below is the code path for this condition. To solve the issue, defer
davinci-mcasp CPU DAI registration to the last step in the audio part of
it. This way, simple-card CPU DAI parsing will be deferred until all
audio components are registered.
Fail Code Path:
simple-card.c: probe starts
simple-card.c: simple_dai_link_of: simple_parse_node(..,cpu,..) returns EPROBE_DEFER, no CPU DAI yet
davinci-mcasp.c: probe starts
davinci-mcasp.c: devm_snd_soc_register_component() register CPU DAI
simple-card.c: probes again, finish CPU DAI parsing and call devm_snd_soc_register_card()
simple-card.c: finish probe
davinci-mcasp.c: *dma_pcm_platform_register() register PCM DMA
davinci-mcasp.c: probe finish

commit 57a1592784d622ecee0b71940c65429173996b33 upstream.
There are 2 issues with interrupt handling in the mxc4005 driver:
1. mxc4005_set_trigger_state() writes MXC4005_REG_INT_MASK1_BIT_DRDYE
(0x01) to INT_MASK1 to enable the interrupt, but to disable the interrupt
it writes ~MXC4005_REG_INT_MASK1_BIT_DRDYE which is 0xfe, so it enables
all other interrupt sources in the INT_SRC1 register. On the MXC4005 this
is not an issue because only bit 0 of the register is used. On the MXC6655
OTOH this is a problem since bit7 is used as TC (Temperature Compensation)
disable bit and writing 1 to this disables Temperature Compensation which
should only be done when running self-tests on the chip.
Write 0 instead of ~MXC4005_REG_INT_MASK1_BIT_DRDYE to disable
the interrupts to fix this.
2. The datasheets for the MXC4005 / MXC6655 do not state what the reset
value for the INT_MASK0 and INT_MASK1 registers is and since these are
write only we also cannot learn this from the hw. Presumably the reset
value for both is all 0, which means all interrupts disabled.
Explicitly set both registers to 0 from mxc4005_chip_init() to ensure
both masks are actually set to 0.

GUSB3PIPECTL.SUSPENDENABLE and GUSB2PHYCFG.SUSPHY should be cleared
during initialization. Suspend during initialization can result in
undefined behavior due to clock synchronization failure, which often
seen as core soft reset timeout.
The programming guide recommended these bits to be cleared during
initialization for DWC_usb3.0 version 1.94 and above (along with
DWC_usb31 and DWC_usb32). The current check in the driver does not
account if it's set by default setting from coreConsultant.
This is especially the case for DRD when switching mode to ensure the
phy clocks are available to change mode. Depending on the
platforms/design, some may be affected more than others. This is noted
in the DWC_usb3x programming guide under the above registers.
Let's just disable them during driver load and mode switching. Restore
them when the controller initialization completes.
Note that some platforms workaround this issue by disabling phy suspend
through "snps,dis_u3_susphy_quirk" and "snps,dis_u2_susphy_quirk" when
they should not need to.

commit ec6ce7075ef879b91a8710829016005dc8170f17 upstream.
The OS descriptors logic had the high/low byte of w_value inverted, causing
the extended properties to not be accessible for interface != 0.
>From the Microsoft documentation:
https://learn.microsoft.com/en-us/windows-hardware/drivers/usbcon/microsoft-os-1-0-descriptors-specification
OS_Desc_CompatID.doc (w_index = 0x4):
- wValue:
High Byte = InterfaceNumber. InterfaceNumber is set to the number of the
interface or function that is associated with the descriptor, typically
0x00. Because a device can have only one extended compat ID descriptor,
it should ignore InterfaceNumber, regardless of the value, and simply
return the descriptor.
Low Byte = 0. PageNumber is used to retrieve descriptors that are larger
than 64 KB. The header section is 16 bytes, so PageNumber is set to 0 for
this request.
We currently do not support >64KB compat ID descriptors, so verify that the
low byte is 0.
OS_Desc_Ext_Prop.doc (w_index = 0x5):
- wValue:
High byte = InterfaceNumber. The high byte of wValue is set to the number
of the interface or function that is associated with the descriptor.
Low byte = PageNumber. The low byte of wValue is used to retrieve
descriptors that are larger than 64 KB. The header section is 10 bytes, so
PageNumber is set to 0 for this request.
We also don't support >64KB extended properties, so verify that the low byte
is 0 and use the high byte for the interface number.

commit fe81f354841641c7f71163b84912b25c169ed8ec upstream.
Testing ohci functionality with qemu's pci-ohci emulation often results
in ohci interface stalls, resulting in hung task timeouts.
The problem is caused by lost interrupts between the emulation and the
Linux kernel code. Additional interrupts raised while the ohci interrupt
handler in Linux is running and before the handler clears the interrupt
status are not handled. The fix for a similar problem in ehci suggests
that the problem is likely caused by edge-triggered MSI interrupts. See
commit 0b60557230ad ("usb: ehci: Prevent missed ehci interrupts with
edge-triggered MSI") for details.
Ensure that the ohci interrupt code handles all pending interrupts before
returning to solve the problem.

commit c78c3644b772e356ca452ae733a3c4de0fb11dc8 upstream.
A virtual SuperSpeed device in the FreeBSD BVCP package
(https://bhyve.npulse.net/) presents an invalid ep0 maxpacket size of 256.
It stopped working with Linux following a recent commit because now we
check these sizes more carefully than before.
Fix this regression by using the bMaxpacketSize0 value in the device
descriptor for SuperSpeed or faster devices, even if it is invalid. This
is a very simple-minded change; we might want to check more carefully for
values that actually make some sense (for instance, no smaller than 64).

Stephen Rostedt reports:
"I went to run my tests on my VMs and the tests hung on boot up.

Timed out after 60 seconds"
and further debugging points to a possible circular locking dependency
between the console_owner locking and the worker pool locking.
Reverting the commit allows Steve's VM to boot to completion again.
[ This may obviously result in the "[TTM] Buffer eviction failed"
messages again, which was the reason for that original revert. But at
this point this seems preferable to a non-booting system... ]

Since 'n' and 'size' arguments of 'kvcalloc()' are multiplied to

commit 2f4a4d63a193 ("ACPI: CPPC: Use access_width over bit_width for system
memory accesses") modified cpc_read()/cpc_write() to use access_width to
read CPC registers.
However, for PCC registers the access width field in the ACPI register
macro specifies the PCC subspace ID. For non-zero PCC subspace ID it is
incorrectly treated as access width. This causes errors when reading
from PCC registers in the CPPC driver.
For PCC registers, base the size of read/write on the bit width field.
The debug message in cpc_read()/cpc_write() is updated to print relevant
information for the address space type used to read the register.
