If CONFIG_NETFILTER_INGRESS is not enabled, nf_ingress() becomes a no-op
because it solely contains an if-clause calling nf_hook_ingress_active(),
for which an empty inline stub exists in <linux/netfilter_ingress.h>.
All the symbols used in the if-clause's body are still available even if
CONFIG_NETFILTER_INGRESS is not enabled.
The additional "#ifdef CONFIG_NETFILTER_INGRESS" in nf_ingress() is thus
unnecessary, so drop it.

====================
WireGuard CI and housekeeping
This is a collection of commits gathered during the last 1.5 weeks since
merging WireGuard. If you'd prefer, I can send tree pull requests
instead, but I figure it might be best for now to just send things as
full patch sets to netdev.
The first part of this adds in the CI test harness that we've been using
for quite some time with success. You can type `make` and get the
selftests running in a fresh VM immediately. This has been an
instrumental tool in developing WireGuard, and I think it'd benefit most
from being in-tree alongside the selftests that are already there. Once
this lands, I plan to get build.wireguard.com building wireguard-
linux.git and net-next.git on every single commit pushed, and do so on a
bunch of different architectures. As this migrates into Linus' tree
eventually and then into net.git, I'll get net.git building there too on
every commit. Future work with this involves generalizing it to include
more networking subsystem tests beyond just WireGuard, but one step at a
time. In the process of porting this to the tree, the builder uncovered
a mistake in the config menu file, which the second commit fixes.
The last three commits are small housekeeping things, fixing spelling
mistakes, replacing call_rcu with kfree_rcu, and removing an unused
include.

WireGuard has been using this on build.wireguard.com for the last
several years with considerable success. It allows for very quick and
iterative development cycles, and supports several platforms.
To run the test suite on your current platform in QEMU:
$ make -C tools/testing/selftests/wireguard/qemu -j$(nproc)
To run it with KASAN and such turned on:
$ DEBUG_KERNEL=yes make -C tools/testing/selftests/wireguard/qemu -j$(nproc)
To run it emulated for another platform in QEMU:
$ ARCH=arm make -C tools/testing/selftests/wireguard/qemu -j$(nproc)
At the moment, we support aarch64_be, aarch64, arm, armeb, i686, m68k,
mips64, mips64el, mips, mipsel, powerpc64le, powerpc, and x86_64.
The system supports incremental rebuilding, so it should be very fast to
change a single file and then test it out and have immediate feedback.
This requires for the right toolchain and qemu to be installed prior.
I've had success with those from musl.cc.
This is tailored for WireGuard at the moment, though later projects
might generalize it for other network testing.

====================
Simplify IPv4 route offload API
Motivation
==========
The aim of this patch set is to simplify the IPv4 route offload API by
making the stack a bit smarter about the notifications it is generating.
This allows driver authors to focus on programming the underlying device
instead of having to duplicate the IPv4 route insertion logic in their
driver, which is error-prone.
This is the first patch set out of a series of four. Subsequent patch
sets will simplify the IPv6 API, add offload/trap indication to routes
and add tests for all the code paths (including error paths). Available
here [1].
Details
=======
Today, whenever an IPv4 route is added or deleted a notification is sent
in the FIB notification chain and it is up to offload drivers to decide
if the route should be programmed to the hardware or not. This is not an
easy task as in hardware routes are keyed by {prefix, prefix length,
table id}, whereas the kernel can store multiple such routes that only
differ in metric / TOS / nexthop info.
This series makes sure that only routes that are actually used in the
data path are notified to offload drivers. This greatly simplifies the
work these drivers need to do, as they are now only concerned with
programming the hardware and do not need to replicate the IPv4 route
insertion logic and store multiple identical routes.
The route that is notified is the first FIB alias in the FIB node with
the given {prefix, prefix length, table ID}. In case the route is
deleted and there is another route with the same key, a replace
notification is emitted. Otherwise, a delete notification is emitted.
The above means that in the case of multiple routes with the same key,
but different TOS, only the route with the highest TOS is notified.
While the kernel can route a packet based on its TOS, this is not
supported by any hardware devices I am familiar with. Moreover, this is
not supported by IPv6 nor by BIRD/FRR from what I could see. Offload
drivers should therefore use the presence of a non-zero TOS as an
indication to trap packets matching the route and let the kernel route
them instead. mlxsw has been doing it for the past two years.
Testing
=======
To ensure there is no degradation in route insertion rates, I averaged
the insertion rate of 512k routes (/24 and /32) over 50 runs. Did not
observe any degradation.
Functional tests are available here [1]. They rely on route trap
indication, which is only added in the last patch set.
In addition, I have been running syzkaller for the past week with all
four patch sets and debug options enabled. Did not observe any problems.
Patch set overview
==================
Patches #1-#8 gradually introduce the new FIB notifications
Patch #9 converts mlxsw to use the new notifications
Patch #10 converts the remaining listeners and removes the old
notifications

* Extend fib_find_alias() with another argument instead of introducing a

Unlike mlxsw, the other listeners to the FIB notification chain do not

With the new notifications mlxsw does not need to handle identical
routes itself, as this is taken care of by the core IPv4 code.
Instead, mlxsw only needs to take care of inserting and removing routes
from the device.

This triggered a warning in the 64 bit optimized ipv6_addr_is_*() functions
because sparse doesn't know that the buffer already points to some data in

therefore be marked with __force to signalize sparse an intended cast to a

Some users complained about problems with r8169 and it turned out that
the generic PHY driver was used instead instead of the dedicated one.
In all cases reason was that r8169.ko was in initramfs, but realtek.ko
not. Manually adding realtek.ko to initramfs fixed the issues.
Root cause seems to be that tools like dracut and genkernel don't
consider softdeps. Add a check for loaded Realtek PHY driver module
and provide the user with a hint if it's not loaded.

At present, if the last frag of paged data in a skb has < PAGE_SIZE
data, we compute the recv_skip_hint as being equal to the size of that
frag and the entire next skb.
Instead, just return the runt frag size as the hint.
recv_skip_hint is used by the application to skip over
bytes that can not be mmaped, so returning a too big

The SO_TXTIME test depends on accurate timers. In some virtualized
environments the test has been reported to be flaky. This is easily
reproduced by disabling kvm acceleration in Qemu.
Allow greater variance in a run and retry to further reduce flakiness.
Observed errors are one of two kinds: either the packet arrives too
early or late at recv(), or it was dropped in the qdisc itself and the
recv() call times out.
In the latter case, the qdisc queues a notification to the error
queue of the send socket. Also explicitly report this cause.

The bond slave actor/partner operating state is exported as
bitfield to userspace, which lacks a way to interpret it, e.g.,
iproute2 only prints the state as a number:
ad_actor_oper_port_state 15
For userspace to interpret the bitfield, the bitfield definitions
should be part of the uapi. The bitfield itself is defined in the
802.3ad standard.
This commit moves the 802.3ad bitfield definitions to uapi.
Related iproute2 patches, soon to be posted upstream, use the new uapi
headers to pretty-print bond slave state, e.g., with ip -d link show

nfp_abm_u32_knode_replace").
The quoted commit does not fix anything and resulted in a bogus
CVE-2019-19076.
If match is NULL then it is known there is no matching entry in
list, hence, calling nfp_abm_u32_knode_delete() is pointless.

====================
netdev: ndo_tx_timeout cleanup
Yet another forward declaration I missed. Hopfully the last one ...
A bunch of drivers want to know which tx queue triggered a timeout,
and virtio wants to do the same.
We actually have the info to hand, let's just pass it on to drivers.
Note: tested with an experimental virtio patch by Julio.
That patch itself isn't ready yet though, so not included.
Other drivers compiled only.
