Pull networking fixes from Jakub Kicinski:
"Including fixes from can, xfrm, wifi, bluetooth, and netfilter.
Lots of various size fixes, the length of the tag speaks for itself.
Most of the 5.17-relevant stuff comes from xfrm, wifi and bt trees
which had been lagging as you pointed out previously. But there's also
a larger than we'd like portion of fixes for bugs from previous
releases.
Three more fixes still under discussion, including and xfrm revert for
uAPI error.
Current release - regressions:

Commit c685c69fba71 ("ixgbe: don't do any AF_XDP zero-copy transmit if
netif is not OK") addressed the ring transient state when
MEM_TYPE_XSK_BUFF_POOL was being configured which in turn caused the
interface to through down/up. Maurice reported that when carrier is not
ok and xsk_pool is present on ring pair, ksoftirqd will consume 100% CPU
cycles due to the constant NAPI rescheduling as ixgbe_poll() states that
there is still some work to be done.
To fix this, do not set work_done to false for a !netif_carrier_ok().

During driver initialization, the pointer of card info, i.e. the
variable 'ci' is required. However, the definition of
'com20020pci_id_table' reveals that this field is empty for some
devices, which will cause null pointer dereference when initializing
these devices.
The following log reveals it:
[ 3.973806] KASAN: null-ptr-deref in range [0x0000000000000028-0x000000000000002f]

While it might work, the current approach is fragile in a few ways:
- whenever members in the structure are shuffled, the pointer will be wrong
- the resource freeing may include more than covered by kfree()

It seems that the lcd2s_redefine_char() has never been properly

by the character number (from 0 to 7), but immediately after that
these bytes are rewritten by the decoded hex stream.

In ("ptp: ocp: Have FPGA fold in ns adjustment for adjtime."), the
ns adjustment was written to the FPGA register, so the clock could
accurately perform adjustments.
However, the adjtime() call passes in a s64, while the clock adjustment
registers use a s32. When trying to perform adjustments with a large
value (37 sec), things fail.
Examine the incoming delta, and if larger than 1 sec, use the original
(coarse) adjustment method. If smaller than 1 sec, then allow the
FPGA to fold in the changes over a 1 second window.

Before these changes elan_suspend() would only disable the regulator
when device_may_wakeup() returns false; whereas elan_resume() would
unconditionally enable it, leading to an enable count imbalance when
device_may_wakeup() returns true.
This triggers the "WARN_ON(regulator->enable_count)" in regulator_put()
when the elan_i2c driver gets unbound, this happens e.g. with the
hot-plugable dock with Elan I2C touchpad for the Asus TF103C 2-in-1.
Fix this by making the regulator_enable() call also be conditional
on device_may_wakeup() returning false.

elan_disable_power() is called conditionally on suspend, where as
elan_enable_power() is always called on resume. This leads to
an imbalance in the regulator's enable count.

in preparation of fixing this.

Some APs misbehave when TWT is used and cause our firmware to crash.
We don't know a reasonable way to detect and work around this problem
in the FW yet. To prevent these crashes, disable TWT in the driver by
stopping to advertise TWT support.

Interrupt() resource
ACPI/x86 devices with a Cherry Trail SoC should have a GpioInt + a regular
GPIO ACPI resource in their ACPI tables.
Some CHT devices have a bug, where the also is bogus interrupt resource
(likely copied from a previous Bay Trail based generation of the device).
The i2c-core-acpi code will assign the bogus, non-working, interrupt
resource to client->irq. Add a workaround to fix this up.

This driver, like several others, uses a chained IRQ for each GPIO bank,
and forwards .irq_set_wake to the GPIO bank's upstream IRQ. As a result,
a call to irq_set_irq_wake() needs to lock both the upstream and
downstream irq_desc's. Lockdep considers this to be a possible deadlock
when the irq_desc's share lockdep classes, which they do by default:
============================================

However, this can never deadlock because the upstream and downstream
IRQs are never the same (nor do they even involve the same irqchip).
Silence this erroneous lockdep splat by applying what appears to be the
usual fix of moving the GPIO IRQs to separate lockdep classes.

The following 'lspci' output shows devices '10000:80:*' are subdevices of

The symptom 'list_add double add' is caused by the following failure
message:
pci 10000:80:01.0: DMAR: Setup RID2PASID failed
pci 10000:80:01.0: Failed to add to iommu group 42: -16
pci 10000:80:03.0: [8086:352b] type 01 class 0x060400
Device 10000:80:01.0 is the subdevice of the VMD device 0000:59:00.5,
so invoking intel_pasid_alloc_table() gets the pasid_table of the VMD
device 0000:59:00.5. Here is call path:
intel_pasid_alloc_table
pci_for_each_dma_alias
get_alias_pasid_table
search_pasid_table
pci_real_dma_dev() in pci_for_each_dma_alias() gets the real dma device
which is the VMD device 0000:59:00.5. However, pte of the VMD device
0000:59:00.5 has been configured during this message "pci 0000:59:00.5:
Adding to iommu group 42". So, the status -EBUSY is returned when
configuring pasid entry for device 10000:80:01.0.
It then invokes dmar_remove_one_dev_info() to release
'struct device_domain_info *' from iommu_devinfo_cache. But, the pasid
table is not released because of the following statement in
__dmar_remove_one_dev_info():
if (info->dev && !dev_is_real_dma_subdevice(info->dev)) {
...
intel_pasid_free_table(info->dev);
}
The subsequent dmar_insert_one_dev_info() operation of device
10000:80:03.0 allocates 'struct device_domain_info *' from
iommu_devinfo_cache. The allocated address is the same address that
is released previously for device 10000:80:01.0. Finally, invoking
device_attach_pasid_table() causes the issue.
`git bisect` points to the offending commit 474dd1c65064 ("iommu/vt-d:
Fix clearing real DMA device's scalable-mode context entries"), which
releases the pasid table if the device is not the subdevice by
checking the returned status of dev_is_real_dma_subdevice().
Reverting the offending commit can work around the issue.
The solution is to prevent from allocating pasid table if those
devices are subdevices of the VMD device.

This JSP2 PCH actually seems to be some special Apple
specific ICP variant rather than a JSP. Make it so. Or at
least all the references to it seem to be some Apple ICL
machines. Didn't manage to find these PCI IDs in any
public chipset docs unfortunately.
The only thing we're losing here with this JSP->ICP change
is Wa_14011294188, but based on the HSD that isn't actually
needed on any ICP based design (including JSP), only TGP
based stuff (including MCC) really need it. The documented
w/a just never made that distinction because Windows didn't
want to differentiate between JSP and MCC (not sure how
they handle hpd/ddc/etc. then though...).

An IPA build problem arose in the linux-next tree the other day.
The problem is that a recent commit adds a new dependency on some
code, and the Kconfig file for IPA doesn't reflect that dependency.
As a result, some configurations can fail to build (particularly
when COMPILE_TEST is enabled).
The recent patch adds calls to qmp_get(), qmp_put(), and qmp_send(),
and those are built based on the QCOM_AOSS_QMP config option. If
that symbol is not defined, stubs are defined, so we just need to
ensure QCOM_AOSS_QMP is compatible with QCOM_IPA, or it's not
defined.
