This patch adds a new helper chk_msk_cestab() to check the current
established connections counter MIB_CURRESTAB in diag.sh. Invoke it
to check the counter during the connection after every chk_msk_inuse().

This patch adds a new helper chk_cestab_nr() to check the current
established connections counter MIB_CURRESTAB. Set the newly added
variables cestab_ns1 and cestab_ns2 to indicate how many connections
are expected in ns1 or ns2.
Invoke check_cestab() to check the counter during the connection in
do_transfer() and invoke chk_cestab_nr() to re-check it when the
connection closed. These checks are embedded in add_tests().

Since commit f5769faeec36 ("net: Namespace-ify sysctl_optmem_max")
optmem_max is per-netns, so need of switching to root namespace.
It seems trivial to keep the old logic working, so going to keep it for
a while (at least, until kernel with netns-optmem_max will be release).
Currently, there is a test that checks that optmem_max limit applies to
TCP-AO keys and a little benchmark that measures linked-list TCP-AO keys
scaling, those are fixed by this.

In unsigned-md5 selftests ip_route_add() is not needed in
client_add_ip(): the route was pre-setup in __test_init() => link_init()
for subnet, rather than a specific ip-address.
Currently, __ip_route_add() mistakenly always sets VRF table
to RT_TABLE_MAIN - this seems to have sneaked in during unsigned-md5
tests debugging. That also explains, why ip_route_add_vrf() ignored
EEXIST, returned by fib6.
Yet, keep EEXIST ignoring in bench-lookups selftests as it's expected
that those selftests may add the same (duplicate) routes.

Since previous commit, MPTCP has support for IP_BIND_ADDRESS_NO_PORT and
IP_LOCAL_PORT_RANGE sockopts.
Add ip4_mptcp and ip6_mptcp fixture variants to ip_local_port_range
selftest to provide selftest coverage for these sockopts.

report pMAC stats
Some devices do not support individual 'pmac' and 'emac' stats.
For such devices, resort to 'aggregate' stats.

Some devices have errata due to which they cannot report ETH_ZLEN (60)
in the rx-min-frag-size. This was foreseen of course, and lldpad has
logic that when we request it to advertise addFragSize 0, it will round
it up to the lowest value that is _actually_ supported by the hardware.
The problem is that the selftest expects lldpad to report back to us the
same value as we requested.
Make the selftest smarter by figuring out on its own what is a
reasonable value to expect.

The setup_loopback and setup_veth use their own way to create namespace.
So let's just re-define server_ns/client_ns to unique name.
At the same time update the namespace name in gro.sh and toeplitz.sh.
As I don't have env to run toeplitz.sh. Here is only the gro test result.
# ./gro.sh
running test ipv4 data
Expected {200 }, Total 1 packets
Received {200 }, Total 1 packets.
...
Gro::large test passed.

Trivial fix for out-of-tree build that I wasn't testing previously:
1. Create a directory for library object files, fixes:
> gcc lib/kconfig.c -Wall -O2 -g -D_GNU_SOURCE -fno-strict-aliasing -I ../../../../../usr/include/ -iquote /tmp/kselftest/kselftest/net/tcp_ao/lib -I ../../../../include/ -o /tmp/kselftest/kselftest/net/tcp_ao/lib/kconfig.o -c
> Assembler messages:
> Fatal error: can't create /tmp/kselftest/kselftest/net/tcp_ao/lib/kconfig.o: No such file or directory
> make[1]: *** [Makefile:46: /tmp/kselftest/kselftest/net/tcp_ao/lib/kconfig.o] Error 1
2. Include $(KHDR_INCLUDES) that's exported by selftests/Makefile, fixes:
> In file included from lib/kconfig.c:6:
> lib/aolib.h:320:45: warning: ‘struct tcp_ao_add’ declared inside parameter list will not be visible outside of this definition or declaration
> 320 | extern int test_prepare_key_sockaddr(struct tcp_ao_add *ao, const char *alg,
> | ^~~~~~~~~~
...
3. While at here, clean-up $(KSFT_KHDR_INSTALL): it's not needed anymore
since commit f2745dc0ba3d ("selftests: stop using KSFT_KHDR_INSTALL")
4. Also, while at here, drop .DEFAULT_GOAL definition: that has a
self-explaining comment, that was valid when I made these selftests
compile on local v4.19 kernel, but not needed since
commit 8ce72dc32578 ("selftests: fix headers_install circular dependency")

MPC backups tests will skip unexpected sometimes (For example, when
compiling kernel with an older version of gcc, such as gcc-8), since
static functions like mptcp_subflow_send_ack also be listed in
/proc/kallsyms, with a 't' in front of it, not 'T' ('T' is for a global
function):
> grep "mptcp_subflow_send_ack" /proc/kallsyms
0000000000000000 T __pfx___mptcp_subflow_send_ack
0000000000000000 T __mptcp_subflow_send_ack
0000000000000000 t __pfx_mptcp_subflow_send_ack
0000000000000000 t mptcp_subflow_send_ack
In this case, mptcp_lib_kallsyms_doesnt_have "mptcp_subflow_send_ack$"
will be false, MPC backups tests will skip. This is not what we expected.
The correct logic here should be: if mptcp_subflow_send_ack is not a
global function in /proc/kallsyms, do these MPC backups tests. So a 'T'
must be added in front of mptcp_subflow_send_ack.

Check multiple keys on a socket:
- rotation on closed socket
- current/rnext operations shouldn't be possible on listen sockets
- current/rnext key set should be the one, that's used on connect()
- key rotations with pseudo-random generated keys
- copying matching keys on connect() and on accept()
At this moment there are 3 tests that are "expected" to fail: a kernel
fix is needed to improve the situation, they are marked XFAIL.

Check that a rare functionality of TCP named self-connect works with
TCP-AO. This "under the cover" also checks TCP simultaneous connect
(TCP_SYN_RECV socket state), which would be harder to check other ways.
In order to verify that it's indeed TCP simultaneous connect, check
the counters TCPChallengeACK and TCPSYNChallenge.
Sample of the output:
> # ./self-connect_ipv6
> 1..4
> # 1738[lib/setup.c:254] rand seed 1696451931
> TAP version 13

Check that both active and passive reset works and correctly sign
segments with TCP-AO or don't send RSTs if not possible to sign.
A listening socket with backlog = 0 gets one connection in accept
queue, another in syn queue. Once the server/listener socket is
forcibly closed, client sockets aren't connected to anything.
In regular situation they would receive RST on any segment, but
with TCP-AO as there's no listener, no AO-key and unknown ISNs,
no RST should be sent.
And "passive" reset, where RST is sent on reply for some segment
(tcp_v{4,6}_send_reset()) - there use TCP_REPAIR to corrupt SEQ numbers,
which later results in TCP-AO signed RST, which will be verified and
client socket will get EPIPE.
No TCPAORequired/TCPAOBad segments are expected during these tests.

The test plan is:
1. check that TCP-AO connection may be restored on another socket
2. check restore with wrong send/recv ISN (checking that they are
part of MAC generation)
3. check restore with wrong SEQ number extension (checking that
high bytes of it taken into MAC generation)

>From the output it's visible that the current simplified approach with
linked-list of MKTs scales quite fine even for thousands of keys.
And that also means that the majority of the time for delete is eaten by
synchronize_rcu() [which I can confirm separately by tracing].

The test plan was (most of tests have all 3 client types):
1. TCP-AO listen (INADDR_ANY)
2. TCP-MD5 listen (INADDR_ANY)
3. non-signed listen (INADDR_ANY)
4. TCP-AO + TCP-MD5 listen (prefix)
5. TCP-AO subprefix add failure [checked in setsockopt-closed.c]
6. TCP-AO out of prefix connect [checked in connect-deny.c]
7. TCP-AO + TCP-MD5 on connect()
8. TCP-AO intersect with TCP-MD5 failure
9. Established TCP-AO: add TCP-MD5 key
10. Established TCP-MD5: add TCP-AO key
11. Established non-signed: add TCP-AO key

Add TCP-AO tests on connect()/accept() pair.
SNMP counters exposed by kernel are very useful here to verify the
expected behavior of TCP-AO.
Expected output for ipv4 version:

Reverse to icmps-discard test: the server accepts ICMPs, using
TCP_AO_CMDF_ACCEPT_ICMP and it is expected to fail under ICMP
flood from client. Test that the default pre-TCP-AO behaviour functions
when TCP_AO_CMDF_ACCEPT_ICMP is set.
Expected output for ipv4 version (in case it receives ICMP_PROT_UNREACH):

With some luck the server may fail with ECONNREFUSED (depending on what
icmp packet was delivered firstly).

Hand-crafted ICMP packets are sent to the server, the server checks for

Provide functions to create selftests dedicated to TCP-AO.
They can run in parallel, as they use temporary net namespaces.
They can be very specific to the feature being tested.
This will allow to create a lot of TCP-AO tests, without complicating
one binary with many --options and to create scenarios, that are
hard to put in bash script that uses one binary.
