This creates a test collection in drivers/net/bonding for bonding
specific kernel selftests.

The first test is a reproducer that provisions a bond and given the
specific order in how the ip-link(8) commands are issued the bond never
transmits an LACPDU frame on any of its slaves.

When we stopped using KSFT_KHDR_INSTALL, a side effect is we also
changed the value of `top_srcdir`. This can be seen by looking at the
code removed by commit 49de12ba06ef
("selftests: drop KSFT_KHDR_INSTALL make target").

(Note though that this commit didn't break this, technically the one
before it did since that's the one that stopped KSFT_KHDR_INSTALL from
being used, even though the code was still there.)

Previously lib.mk reconfigured `top_srcdir` when KSFT_KHDR_INSTALL was
being used. Now, that's no longer the case.

As a result, the path to gup_test.h in vm/Makefile was wrong, and
since it's a dependency of all of the vm binaries none of them could
be built. Instead, we'd get an "error" like:

    make[1]: *** No rule to make target
        '/[...]/tools/testing/selftests/vm/compaction_test', needed by
	'all'.  Stop.

So, modify lib.mk so it once again sets top_srcdir to the root of the
kernel tree.

netfilter: conntrack and nf_tables bug fixes

The following patchset contains netfilter fixes for net.

Broken since 5.19:
  A few ancient connection tracking helpers assume TCP packets cannot
  exceed 64kb in size, but this isn't the case anymore with 5.19 when
  BIG TCP got merged, from myself.

Regressions since 5.19:
  1. 'conntrack -E expect' won't display anything because nfnetlink failed
     to enable events for expectations, only for normal conntrack events.

  2. partially revert change that added resched calls to a function that can
     be in atomic context.  Both broken and fixed up by myself.

Broken for several releases (up to original merge of nf_tables):
  Several fixes for nf_tables control plane, from Pablo.
  This fixes up resource leaks in error paths and adds more sanity
  checks for mutually exclusive attributes/flags.

Kconfig:
  NF_CONNTRACK_PROCFS is very old and doesn't provide all info provided
  via ctnetlink, so it should not default to y. From Geert Uytterhoeven.

Selftests:
  rework nft_flowtable.sh: it frequently indicated failure; the way it
  tried to detect an offload failure did not work reliably.

This test fails on current kernel releases because the flotwable path
now calls dst_check from packet path and will then remove the offload.

Test script has two purposes:
1. check that file (random content) can be sent to other netns (and vv)
2. check that the flow is offloaded (rather than handled by classic
   forwarding path).

Since dst_check is in place, 2) fails because the nftables ruleset in
router namespace 1 intentionally blocks traffic under the assumption
that packets are not passed via classic path at all.

Rework this: Instead of blocking traffic, create two named counters, one
for original and one for reverse direction.

The first three test cases are handled by classic forwarding path
(path mtu discovery is disabled and packets exceed MTU).

But all other tests enable PMTUD, so the originator and responder are
expected to lower packet size and flowtable is expected to do the packet
forwarding.

For those tests, check that the packet counters (which are only
incremented for packets that are passed up to classic forward path)
are significantly lower than the file size transferred.

I've tested that the counter-checks fail as expected when the 'flow add'
statement is removed from the ruleset.

"ns1" is a too generic name, use a random suffix to avoid
errors when such a netns exists.  Also allows to run multiple
instances of the script in parallel.

OpenSSL 3.0 deprecates some of the functions used in the SGX
selftests, causing build errors on new distros. For now ignore
the warnings until support for the functions is no longer
available and mark FIXME so that it can be clear this should
be removed at some point.
