Syzcaller UBSAN crash occurs in rds_cmsg_recv(),
which reads inc->i_rx_lat_trace[j + 1] with index 4 (3 + 1),
but with array size of 4 (RDS_RX_MAX_TRACES).
Here 'j' is assigned from rs->rs_rx_trace[i] and in-turn from
trace.rx_trace_pos[i] in rds_recv_track_latency(),
with both arrays sized 3 (RDS_MSG_RX_DGRAM_TRACE_MAX). So fix the
off-by-one bounds check in rds_recv_track_latency() to prevent
a potential crash in rds_cmsg_recv().

Starting from Linux 5.16 kernel, Tx timeout mechanism was added
in the virtio_net driver which prints the "Tx timeout" warning
message when a packet stays in Tx queue for too long. Below is an
example of the reported message:
"[494105.316739] virtio_net virtio1 tmfifo_net0: TX timeout on
queue: 0, sq: output.0, vq: 0×1, name: output.0, usecs since
last trans: 3079892256".
This issue could happen when external host driver which drains the
FIFO is restared, stopped or upgraded. To avoid such confusing
"Tx timeout" messages, this commit adds logic to drop the outstanding
Tx packet if it's not able to transmit in two seconds due to Tx FIFO
full, which can be considered as congestion or out-of-resource drop.
This commit also handles the special case that the packet is half-
transmitted into the Tx FIFO. In such case, the packet is discarded
with remaining length stored in vring->rem_padding. So paddings with
zeros can be sent out when Tx space is available to maintain the
integrity of the packet format. The padded packet will be dropped on
the receiving side.

The HW has the capability to check each frame if it is a PTP frame,
which domain it is, which ptp frame type it is, different ip address in
the frame. And if one of these checks fail then the frame is not
timestamp. Most of these checks were disabled except checking the field
minorVersionPTP inside the PTP header. Meaning that once a partner sends
a frame compliant to 8021AS which has minorVersionPTP set to 1, then the
frame was not timestamp because the HW expected by default a value of 0
in minorVersionPTP. This is exactly the same issue as on lan8841.
Fix this issue by removing this check so the userspace can decide on this.

dpll: fix unordered unbind/bind registerer issues
Fix issues when performing unordered unbind/bind of a kernel modules

Currently only serialized bind/unbind of such use case works, fix

$ echo 0000:af:00.0 > /sys/bus/pci/drivers/ice/unbind
$ echo 0000:af:00.1 > /sys/bus/pci/drivers/ice/unbind

In case of multiple kernel module instances using the same dpll device:
if only one registers dpll device, then only that one can register
directly connected pins with a dpll device. When unregistered parent is
responsible for determining if the muxed pin can be registered with it
or not, the drivers need to be loaded in serialized order to work
correctly - first the driver instance which registers the direct pins
needs to be loaded, then the other instances could register muxed type
pins.
Allow registration of a pin with a parent even if the parent was not
yet registered, thus allow ability for unserialized driver instance
load order.
Do not WARN_ON notification for unregistered pin, which can be invoked
for described case, instead just return error.

If parent pin was unregistered but child pin was not, the userspace
would see the "zombie" pins - the ones that were registered with
a parent pin (dpll_pin_on_pin_register(..)).
Technically those are not available - as there is no dpll device in the
system. Do not dump those pins and prevent userspace from any
interaction with them. Provide a unified function to determine if the
pin is available and use it before acting/responding for user requests.

When a kernel module is unbound but the pin resources were not entirely
freed (other kernel module instance of the same PCI device have had kept
the reference to that pin), and kernel module is again bound, the pin
properties would not be updated (the properties are only assigned when
memory for the pin is allocated), prop pointer still points to the
kernel module memory of the kernel module which was deallocated on the
unbind.
If the pin dump is invoked in this state, the result is a kernel crash.
Prevent the crash by storing persistent pin properties in dpll subsystem,
copy the content from the kernel module when pin is allocated, instead of
using memory of the kernel module.

If pin type is not expected, or pin properities failed to allocate
memory, the unwind error path shall not destroy pin's xarrays, which
were not yet initialized.
Add new goto label and use it to fix broken error path.

There are few places on the receive path where packet receives and

The TUN can be used as vhost-net backend, and it is necessary to
count the packets transmitted from TUN to vhost-net/virtio-net.
However, there are some places in the receive path that were not
taken into account when using XDP. It would be beneficial to also
include new accounting for successfully received bytes using
dev_sw_netstats_rx_add.

The commit 8ae1aff0b331 ("tuntap: split out XDP logic") includes
dropped counter for XDP_DROP, XDP_ABORTED, and invalid XDP actions.
Unfortunately, that commit missed the dropped counter when error
occurs during XDP_TX and XDP_REDIRECT actions. This patch fixes
this issue.

After more investigation, I've found that it's not the panel driver
config that needs to be modified to invert the data polarity, but
the FIMD config.
Add the missing invert-vclk option that is required to get the display
to work correctly.

The cmu_misc clock-names were renamed to just "bus" and "sss" because
naming is local to the module, so cmu_misc is implied. As the bindings
and the device tree have not made a release yet, comply with the
renamed clocks.

The raw interrupt status of eic maybe set before the interrupt is enabled,
since the eic interrupt has a latch function, which would trigger the
interrupt event once enabled it from user side. To solve this problem,
interrupts generated before setting the interrupt trigger type are ignored.

The acpi4asus project appears to be defunct, according to:
https://sourceforge.net/p/acpi4asus/mailman/acpi4asus-user/
the last posts to the list were done in May 2020 and even then
they were mostly spam.
And the http://acpi4asus.sf.net website still talks about 2.6.x kernels.
Drop the defunct mailing-list and update the W: entry to point to
the new up2date https://asus-linux.org/ site.
