Networking drivers implementing PTP clocks and kernel socket code
handling hardware timestamps use the 64-bit signed ktime_t type counting
nanoseconds. When a PTP clock reaches the maximum value in year 2262,
the timestamps returned to applications will overflow into year 1667.
The same thing happens when injecting a large offset with
clock_adjtime(ADJ_SETOFFSET).
The commit 7a8e61f847 ("timekeeping: Force upper bound for setting
CLOCK_REALTIME") limited the maximum accepted value setting the system
clock to 30 years before the maximum representable value (i.e. year
2232) to avoid the overflow, assuming the system will not run for more
than 30 years.
Enforce the same limit for PTP clocks. Don't allow negative values and
values closer than 30 years to the maximum value. Drivers may implement
an even lower limit if the hardware registers cannot represent the whole
interval between years 1970 and 2262 in the required resolution.

The icmp_ndo_send function was originally introduced to ensure proper
rate limiting when icmp_send is called by a network device driver,
where the packet's source address may have already been transformed
by SNAT.
However, the original implementation only considers the
IP_CT_DIR_ORIGINAL direction for SNAT and always replaced the packet's
source address with that of the original-direction tuple. This causes
two problems:
1. For SNAT:
Reply-direction packets were incorrectly translated using the source
address of the CT original direction, even though no translation is
required.
2. For DNAT:
Reply-direction packets were not handled at all. In DNAT, the original
direction's destination is translated. Therefore, in the reply
direction the source address must be set to the reply-direction
source, so rate limiting works as intended.
Fix this by using the connection direction to select the correct tuple
for source address translation, and adjust the pre-checks to handle
reply-direction packets in case of DNAT.
Additionally, wrap the `ct->status` access in READ_ONCE(). This avoids
possible KCSAN reports about concurrent updates to `ct->status`.

Signed-off-by: Danilo Krummrich <dakr@kernel.org>
NovaCore has so far been too imprecise about figuring out if .probe()
has found a supported PCI PF (Physical Function). By that I mean:
.probe() sets up BAR0 (which involves a lot of very careful devres and
Device<Bound> details behind the scenes). And then if it is dealing with
a non-supported device such as the .1 audio PF on many GPUs, it fails
out due to an unexpected BAR0 size. We have been fortunate that the BAR0
sizes are different.
Really, we should be filtering on PCI class ID instead. These days I
think we can confidently pick out Nova's supported PF's via PCI class
ID. And if not, then we'll revisit.
The approach here is to filter on "Display VGA" or "Display 3D", which
is how PCI class IDs express "this is a modern GPU's PF".

USB connector bindings describe a ports subnode, which describes how
its High-/SuperSpeed data lines (as well as the SBU pins for Type-C)
are connected.
On Linux, skipping the graph results in the 'connect_type' sysfs
attribute returning 'unknown', instead of 'hotplug' or similar. This in
turn is parsed by some operating systems (such as CrOS), to e.g. make
security policy decisions.
Define ports {} for the DWC controller & the QMPPHY and connect them
together for the SS lanes.
Leave the DP endpoint unconnected for now, as both Aspire 1 and the
Chromebooks (unmerged, see [1]) seem to have a non-trivial topology.
Take the creative liberty to add a newline before its ports' subnodes
though.

firmware does not configure the display (e.g. because a different display
is selected for output in the UEFI settings), then the display fails to
come up and there are several errors in the kernel log:
[drm:dpu_encoder_phys_vid_wait_for_commit_done:544] [dpu error]vblank timeout: 80020041
[drm:dpu_kms_wait_for_commit_done:524] [dpu error]wait for commit done returned -110
[drm:dpu_encoder_frame_done_timeout:2715] [dpu error]enc40 frame done timeout
...
Fix this by adding the missing pinctrl for gpio119 (func1/edp0_hot and
bias-disable according to the ACPI DSDT), which is defined as
&edp0_hpd_default template in x1e80100.dtsi.
