Przemek suggests that I shouldn't accuse GCC of witchcraft,
there is a simpler explanation for why we need manual define.
scripts/headers_install.sh modifies the guard, removing _UAPI.
That's why including a kernel header from the tree and from
/usr leads to duplicate definitions.
This also solves the mystery of why I needed to include
the header conditionally. I had the wrong guards for most
cases but ethtool.

When mirroring to a gretap in hardware the device expects to be
programmed with the egress port and all the encapsulating headers. This
requires the driver to resolve the path the packet will take in the
software data path and program the device accordingly.
If the path cannot be resolved (in this case because of an unresolved
neighbor), then mirror installation fails until the path is resolved.
This results in a race that causes the test to sometimes fail.
Fix this by setting the neighbor's state to permanent in a couple of
tests, so that it is always valid.

Selftests are supposed to run on any kernels, including the old ones not
supporting all MPTCP features.
One of them is the MPTCP MIB counters introduced in commit fc518953bc
("mptcp: add and use MIB counter infrastructure") and more later. The
MPTCP Join selftest heavily relies on these counters.
If a counter is not supported by the kernel, it is not displayed when
using 'nstat -z'. We can then detect that and skip the verification. A
new helper (get_counter()) has been added recently in the -net tree to
do the required checks and return an error if the counter is not
available.
This commit is similar to the one with the same title applied in the
-net tree but it modifies code only present in net-next for the moment,
see the Fixes commit below.
While at it, we can also remove the use of ${extra_msg} variable which
is never assigned in chk_rm_tx_nr() function and use 'echo' without '-n'
parameter.

In a future patch, mlxsw will start adding RIFs to uppers of front panel
port netdevices, if they have an IP address.
At the time that the front panel port is enslaved to the bridge, the bridge
MAC address does not have the same prefix as other interfaces in the
system. On Nvidia Spectrum-1 machines all the RIFs have to have the same
38-bit MAC address prefix. Since the bridge does not obey this limitation,
the RIF cannot be created, and the enslavement attempt is vetoed on the
grounds of the configuration not being offloadable.
The bridge eventually inherits MAC address from its first member, after the
enslavement is acked. A number of (mainly VXLAN) selftests already work
around the problem by setting the MAC address to whatever it will
eventually be anyway. Do the same for this selftest.

- Fix MAINTAINERS file to point to proper mailing list for rtla and rv
The mailing list pointed to linux-trace-devel instead of
linux-trace-kernel. The former is for the tracing libraries and the
latter is for anything in the Linux kernel tree. The wrong mailing
list was used because linux-trace-kernel did not exist when rtla and
rv were created.
- User events:
- Fix matching of dynamic events to their user events
When user writes to dynamic_events file, a lookup of the
registered dynamic events is made, but there were some cases that
a match could be incorrectly made.
- Add auto cleanup of user events
Have the user events automatically get removed when the last
reference (file descriptor) is closed. This was asked for to
prevent leaks of user events hanging around needing admins to
clean them up.
- Add persistent logic (but not let user space use it yet)
In some cases, having a persistent user event (one that does not
get cleaned up automatically) is useful. But there's still debates
about how to expose this to user space. The infrastructure is
added, but the API is not.

Currently the MM selftests attempt to work out the target architecture by
using CROSS_COMPILE or otherwise querying the host machine, storing the
target architecture in a variable called MACHINE rather than the usual
ARCH though as far as I can tell (including for x86_64) the value is the
same as we would use for architecture.
When cross compiling with LLVM we don't need a CROSS_COMPILE as LLVM can
support many target architectures in a single build so this logic does not
work, CROSS_COMPILE is not set and we end up selecting tests for the host
rather than target architecture. Fix this by using the more standard ARCH
to describe the architecture, taking it from the environment if specified.

The vrf-xfrm-tests tests use the hmac(md5) and cbc(des3_ede)
algorithms for performing authentication and encryption, respectively.
This causes the tests to fail when fips=1 is set, since these algorithms
are not allowed in FIPS mode. Therefore, switch from hmac(md5) and
cbc(des3_ede) to hmac(sha1) and cbc(aes), which are FIPS compliant.

Before executing each test from a fixture, FIXTURE_SETUP is run once.
When SKIP is used in FIXTURE_SETUP, the setup function returns early
but the test still proceeds to run, unless another SKIP macro is used
within the test definition, leading to some code repetition. Therefore,
allow tests to be skipped directly from the setup function.

Pull networking fixes from Jakub Kicinski:
"Including fixes from wireless, and netfilter.
Selftests excluded - we have 58 patches and diff of +442/-199, which
isn't really small but perhaps with the exception of the WiFi locking
change it's old(ish) bugs.
We have no known problems with v6.4.
The selftest changes are rather large as MPTCP folks try to apply
Greg's guidance that selftest from torvalds/linux should be able to
run against stable kernels.
Last thing I should call out is the DCCP/UDP-lite deprecation notices.
We are fairly sure those are dead, but if we're wrong reverting them
back in won't be fun.

- cfg80211: fix double lock bug in reg_wdev_chan_valid()
- iwlwifi: mvm: spin_lock_bh() to fix lockdep regression

Previously, timestamps were printed using "%lld.%u" which is incorrect
for nanosecond values lower than 100,000,000 as they're fractional
digits, therefore leading zeros are meaningful.
This patch changes the format strings to "%lld.%09u" in order to add
leading zeros to the nanosecond value.

The inability to include the uAPI headers directly in tools/
is one of the bigger annoyances of compiling user space code.
Most projects trade the pain for smaller inconvenience of having
to copy the headers under tools/include.
In case of netlink headers I think that we can avoid both.
Netlink family headers are simple and should be self-contained.
We can try to twiddle the Makefile a little to force-include
just the family header, and use system headers for the rest.
This works fairly well. There are two warts - for some reason
if we specify -include $path/family.h as a compilation flag,
the #ifdef header guard does not seem to work. So we need
to throw the guard in on the command line as well. Seems like
GCC detects that the header is different and tries to include
both. Second problem is that make wants hash sign to be escaped
or not depending on the version. Sigh.

Now that user_events does not honor persist events the dynamic_events
file cannot be easily used to test parsing and matching cases.
Update dyn_test to use the direct ABI file instead of dynamic_events so
that we still have testing coverage until persist events and
dynamic_events file integration has been decided.

Setting the IPv6 address generation mode of a net device during its
creation never worked, but after commit b0ad3c1790 ("rtnetlink: call
validate_linkmsg in rtnl_create_link") it explicitly fails [1]. The
failure is caused by the fact that validate_linkmsg() is called before
the net device is registered, when it still does not have an 'inet6_dev'.
Likewise, raising the net device before setting the address generation
mode is meaningless, because by the time the mode is set, the address
has already been generated.
Therefore, fix the test to first create the net device, then set its
IPv6 address generation mode and finally bring it up.

Setting very small value of db like 10ms introduces rounding errors when
converting to/from jiffies on some kernel configs. For example, on 250hz
the actual value will be set to 12ms which causes the test to fail:
# $ sudo ./tdc.py -d eth2 -e 3410
# -- ns/SubPlugin.__init__
# Test 3410: Create SFB with db setting
#
# All test results:

# 1..1
# not ok 1 3410 - Create SFB with db setting
# Could not match regex pattern. Verify command output:
# qdisc sfb 1: root refcnt 2 rehash 600s db 12ms limit 1000p max 25p target 20p increment 0.000503548 decrement 4.57771e-05 penalty_rate 10pps penalty_burst 20p
Set the value to 100ms instead which currently seem to work on 100hz,
250hz, 300hz and 1000hz kernel configs.
