Currently, "active reset" cases are flaky, because select() is called
for 3 sockets, while only 2 are expected to receive RST.
The idea of the third socket was to get into request_sock_queue,
but the test mistakenly attempted to connect() after the listener
socket was shut down.
Repair this test, it's important to check the different kernel
code-paths for signing RST TCP-AO segments.

The ethtool dump includes the lanes parameter only when the port is up.
Therefore, the ethtool_lanes.sh test waits for ports to come before testing
the lanes parameter.
In some cases, the test considers the port as up, but the lanes parameter
is not yet dumped although assumed to be, resulting in ethtool_lanes.sh
test failure.
To avoid that, ensure that the lanes parameter is indeed dumped by waiting
for it explicitly, before preforming the test cases.

The tests use the constant TC_HIT_TIMEOUT when waiting on the counter
values. However it does not include tc_common.sh where the counter is
specified. The test has been robust in our testing, which means the counter
is bumped quickly enough that the updated value is available already on the
first iteration. Nevertheless it's not correct. Include tc_common.sh as
appropriate.

Some log_test calls are done in a loop, and lead to the same log output.
This might prove tricky to deduplicate for automated tools. Instead, roll
the unique information from log_info to log_test, and drop the log_info.
This also leads to more compact and clearer output.
This change prompts rewording the messages so that they are not excessively
long.
Some check_err messages do not indicate what the issue actually is, so
reword them to say it's a "ping with", like is the case in some other
instances in this test.

When rx-pktsNtoM reports a range that involves very low-valued range, such
as 0-64, the calculated length of the packet will be -4, because FCS is
subtracted from the value. mausezahn then confuses the value for an option
and bails out. As a result, the test dumps many mausezahn error messages.
Instead, cap the value at 0. mausezahn will use an appropriate minimum
packet length.

Bodies of busywait() and slowwait() functions are almost identical. Extract
the common code into a helper, loopy_wait, and convert busywait() and
slowwait() into trivial wrappers.
Moreover, the fact that slowwait() uses seconds for units is really not
intuitive, and the comment does not help much. Instead make the unit part
of the name of the argument to further clarify what units are expected.

The commit fc8b2a619469
("net: more strict VIRTIO_NET_HDR_GSO_UDP_L4 validation")
adds check of potential number of UDP segments vs
UDP_MAX_SEGMENTS in linux/virtio_net.h.
After this change certification test of USO guest-to-guest
transmit on Windows driver for virtio-net device fails,
for example with packet size of ~64K and mss of 536 bytes.
In general the USO should not be more restrictive than TSO.
Indeed, in case of unreasonably small mss a lot of segments
can cause queue overflow and packet loss on the destination.
Limit of 128 segments is good for any practical purpose,
with minimal meaningful mss of 536 the maximal UDP packet will
be divided to ~120 segments.
The number of segments for UDP packets is validated vs
UDP_MAX_SEGMENTS also in udp.c (v4,v6), this does not affect
quest-to-guest path but does affect packets sent to host, for
example.
It is important to mention that UDP_MAX_SEGMENTS is kernel-only
define and not available to user mode socket applications.
In order to request MSS smaller than MTU the applications
just uses setsockopt with SOL_UDP and UDP_SEGMENT and there is
no limitations on socket API level.

The settings file is removed for now:
It was used to increase the timeout to avoid slow scripts from getting

__noreturn
After commit 6d029c25b71f ("selftests/timers/posix_timers: Reimplement
check_timer_distribution()"), clang warns:
tools/testing/selftests/timers/../kselftest.h:398:6: warning: variable 'major' is used uninitialized whenever '||' condition is true [-Wsometimes-uninitialized]
398 | if (uname(&info) || sscanf(info.release, "%u.%u.", &major, &minor) != 2)

tools/testing/selftests/timers/../kselftest.h:395:20: note: initialize the variable 'major' to silence this warning
395 | unsigned int major, minor;

| = 0
This is a false positive because if uname() fails, ksft_exit_fail_msg()
will be called, which unconditionally calls exit(), a noreturn function.
However, clang does not know that ksft_exit_fail_msg() will call exit() at
the point in the pipeline that the warning is emitted because inlining has
not occurred, so it assumes control flow will resume normally after
ksft_exit_fail_msg() is called.
Make it clear to clang that all of the functions that call exit()
unconditionally in kselftest.h are noreturn transitively by marking them
explicitly with '__attribute__((__noreturn__))', which clears up the
warning above and any future warnings that may appear for the same reason.

Extend vmx_dirty_log_test to include accesses made by L2 when EPT is
disabled.
This commit adds explicit coverage of a bug caught by syzkaller, where
the TDP MMU would clear D-bits instead of write-protecting SPTEs being
used to map an L2, which only happens when L1 does not enable EPT,
causing writes made by L2 to not be reflected in the dirty log when PML
is enabled:
$ ./vmx_dirty_log_test
Nested EPT: disabled
==== Test Assertion Failure ====
x86_64/vmx_dirty_log_test.c:151: test_bit(0, bmap)
pid=72052 tid=72052 errno=4 - Interrupted system call
(stack trace empty)
Page 0 incorrectly reported clean
Opportunistically replace the volatile casts with {READ,WRITE}_ONCE().
