When we fill up a receive VQ, try_fill_recv currently tries to count
kicks using a 64 bit stats counter. Turns out, on a 32 bit kernel that
uses a seqcount. sequence counts are "lock" constructs where you need to
make sure that writers are serialized.

In turn, this means that we mustn't run two try_fill_recv concurrently.
Which of course we don't. We do run try_fill_recv sometimes from a
softirq napi context, and sometimes from a fully preemptible context,
but the later always runs with napi disabled.

However, when it comes to the seqcount, lockdep is trying to enforce the
rule that the same lock isn't accessed from preemptible and softirq
context - it doesn't know about napi being enabled/disabled. This causes
a false-positive warning:

WARNING: inconsistent lock state
...
inconsistent {SOFTIRQ-ON-W} -> {IN-SOFTIRQ-W} usage.

As a work around, shut down the warning by switching
to u64_stats_update_begin_irqsave - that works by disabling
interrupts on 32 bit only, is a NOP on 64 bit.

that the frontend does not need counters, this hw stats type request
never fails. The FLOW_ACTION_HW_STATS_DISABLED type explicitly requests
the driver to disable the stats, however, if the driver cannot disable
counters, it bails out.

TCA_ACT_HW_STATS_* maintains the 1:1 mapping with FLOW_ACTION_HW_STATS_*
except by disabled which is mapped to FLOW_ACTION_HW_STATS_DISABLED
(this is 0 in tc). Add tc_act_hw_stats() to perform the mapping between

wireguard fixes for 5.7-rc5

With Ubuntu and Debian having backported this into their kernels, we're
finally seeing testing from places we hadn't seen prior, which is nice.
With that comes more fixes:

1) The CI for PPC64 was running with extremely small stacks for 64-bit,
   causing spurious crashes in surprising places.

2) There's was an old leftover routing loop restriction, which no longer
   makes sense given the queueing architecture, and was causing problems
   for people who really did want nested routing.

3) Not yielding our kthread on CONFIG_PREEMPT_VOLUNTARY systems caused
   RCU stalls and other issues, reported by Wang Jian, with the fix
   suggested by Sultan Alsawaf.

4) Clang spewed warnings in a selftest for CONFIG_IPV6=n, reported by
   Arnd Bergmann.

5) A complicated if statement was simplified to an assignment while also
   making the likely/unlikely hinting more correct and simple, and
   increasing readability, suggested by Sultan.

Patches (2) and (3) have Fixes: lines and are probably good candidates
for stable.

It's very unlikely that send will become true. It's nearly always false
between 0 and 120 seconds of a session, and in most cases becomes true
only between 120 and 121 seconds before becoming false again. So,
unlikely(send) is clearly the right option here.

What happened before was that we had this complex boolean expression
with multiple likely and unlikely clauses nested. Since this is
evaluated left-to-right anyway, the whole thing got converted to
unlikely. So, we can clean this up to better represent what's going on.

The generated code is the same.

Signed-off-by: David S. Miller <davem@davemloft.net>

It's already possible to create two different interfaces and loop
packets between them. This has always been possible with tunnels in the
kernel, and isn't specific to wireguard. Therefore, the networking stack
already needs to deal with that. At the very least, the packet winds up
exceeding the MTU and is discarded at that point. So, since this is
already something that happens, there's no need to forbid the not very
exceptional case of routing a packet back to the same interface; this
loop is no different than others, and we shouldn't special case it, but
rather rely on generic handling of loops in general. This also makes it
easier to do interesting things with wireguard such as onion routing.

At the same time, we add a selftest for this, ensuring that both onion
routing works and infinite routing loops do not crash the kernel. We
also add a test case for wireguard interfaces nesting packets and
sending traffic between each other, as well as the loop in this case
too. We make sure to send some throughput-heavy traffic for this use
case, to stress out any possible recursion issues with the locks around
workqueues.

The Segment Routing Header (SRH) which defines the SRv6 dataplane is defined
in RFC8754.

RFC8754 (section 4.1) defines the SR source node behavior which encapsulates
packets into an outer IPv6 header and SRH. The SR source node encodes the
full list of Segments that defines the packet path in the SRH. Then, the
first segment from list of Segments is copied into the Destination address
of the outer IPv6 header and the packet is sent to the first hop in its path
towards the destination.

If the Segment list has only one segment, the SR source node can omit the SRH
as he only segment is added in the destination address.

RFC8754 (section 4.1.1) defines the Reduced SRH, when a source does not
require the entire SID list to be preserved in the SRH. A reduced SRH does
not contain the first segment of the related SR Policy (the first segment is
the one already in the DA of the IPv6 header), and the Last Entry field is
set to n-2, where n is the number of elements in the SR Policy.

RFC8754 (section 4.3.1.1) defines the SRH processing and the logic to
validate the SRH (S09, S10, S11) which works for both reduced and
non-reduced behaviors.

This patch updates seg6_validate_srh() to validate the SRH as per RFC8754.

It looks like the sja1105 external timestamping input is not as generic
as we thought. When fed a signal with 50% duty cycle, it will timestamp
both the rising and the falling edge. When fed a short pulse signal,
only the timestamp of the falling edge will be seen in the PTPSYNCTS
register, because that of the rising edge had been overwritten. So the
moral is: don't feed it short pulse inputs.

Luckily this is not a complete deal breaker, as we can still work with
1 Hz square waves. But the problem is that the extts polling period was
not dimensioned enough for this input signal. If we leave the period at
half a second, we risk losing timestamps due to jitter in the measuring
process. So we need to increase it to 4 times per second.

Also, the very least we can do to inform the user is to deny any other
flags combination than with PTP_RISING_EDGE and PTP_FALLING_EDGE both
set.

Since 'value' is declared as unsigned long, the following statement is
always false.
	value < 0

So let's remove it.

When both CONFIG_DEBUG_FS and CONFIG_PM_SLEEP are disabled, the
functions that got moved out of the #ifdef section now cause
a warning:

drivers/platform/x86/intel_pmc_core.c:654:13: error: 'pmc_core_lpm_display' defined but not used [-Werror=unused-function]
  654 | static void pmc_core_lpm_display(struct pmc_dev *pmcdev, struct device *dev,
      |             ^~~~~~~~~~~~~~~~~~~~
drivers/platform/x86/intel_pmc_core.c:617:13: error: 'pmc_core_slps0_display' defined but not used [-Werror=unused-function]
  617 | static void pmc_core_slps0_display(struct pmc_dev *pmcdev, struct device *dev,
      |             ^~~~~~~~~~~~~~~~~~~~~~

Rather than add even more #ifdefs here, remove them entirely and
let the compiler work it out, it can actually get rid of all the
debugfs calls without problems as long as the struct member is
there.

The two PM functions just need a __maybe_unused annotations to avoid
another warning instead of the #ifdef.

asus-nb-wmi does not add any extra functionality on these Asus
Transformer books. They have detachable keyboards, so the hotkeys are
send through a HID device (and handled by the hid-asus driver) and also
the rfkill functionality is not used on these devices.

Besides not adding any extra functionality, initializing the WMI interface
on these devices actually has a negative side-effect. For some reason
the \_SB.ATKD.INIT() function which asus_wmi_platform_init() calls drives
GPO2 (INT33FC:02) pin 8, which is connected to the front facing webcam LED,
high and there is no (WMI or other) interface to drive this low again
causing the LED to be permanently on, even during suspend.

This commit adds a blacklist of DMI system_ids on which not to load the
asus-nb-wmi and adds these Transformer books to this list. This fixes
the webcam LED being permanently on under Linux.

Jasper Lake uses Icelake PCH IPs and the S0ix debug interfaces are same as
Icelake. It uses SLP_S0_DBG register latch/read interface from Icelake
generation. It doesn't use Tiger Lake LPM debug registers. Change the
Jasper Lake S0ix debug interface to use the ICL reg map.

In function nfp_abm_vnic_set_mac, pointer nsp is allocated by nfp_nsp_open.
But when nfp_nsp_has_hwinfo_lookup fail, the pointer is not released,
which can lead to a memory leak bug. Fix this issue by adding
nfp_nsp_close(nsp) in the error path.
