2114e83381 selftests: forwarding: Avoid failures to source net/lib.sh
The expression "source ../lib.sh" added to net/forwarding/lib.sh in commit
25ae948b4478 ("selftests/net: add lib.sh") does not work for tests outside
net/forwarding which source net/forwarding/lib.sh (1). It also does not
work in some cases where only a subset of tests are exported (2).

Avoid the problems mentioned above by replacing the faulty expression with
a copy of the content from net/lib.sh which is used by files under
net/forwarding.

A more thorough solution which avoids duplicating content between
net/lib.sh and net/forwarding/lib.sh has been posted here:
https://lore.kernel.org/netdev/20231222135836.992841-1-bpoirier@nvidia.com/

The approach in the current patch is a stopgap solution to avoid submitting
large changes at the eleventh hour of this development cycle.

Example of problem 1)

tools/testing/selftests/drivers/net/bonding$ ./dev_addr_lists.sh
./net_forwarding_lib.sh: line 41: ../lib.sh: No such file or directory
TEST: bonding cleanup mode active-backup                            [ OK ]
TEST: bonding cleanup mode 802.3ad                                  [ OK ]
TEST: bonding LACPDU multicast address to slave (from bond down)    [ OK ]
TEST: bonding LACPDU multicast address to slave (from bond up)      [ OK ]

An error message is printed but since the test does not use functions from
net/lib.sh, the test results are not affected.

Example of problem 2)

tools/testing/selftests$ make install TARGETS="net/forwarding"
tools/testing/selftests$ cd kselftest_install/net/forwarding/
tools/testing/selftests/kselftest_install/net/forwarding$ ./pedit_ip.sh veth{0..3}

TEST: dev veth2 egress pedit ip6 dst set 2001:db8:2::1              [FAIL]
        Expected to get 10 packets, but got .

In this case, the test results are affected.

4e321d590c selftests/net: fix GRO coalesce test and add ext header coalesce tests
Currently there is no test which checks that IPv6 extension header packets
successfully coalesce. This commit adds a test, which verifies two IPv6
packets with HBH extension headers do coalesce, and another test which
checks that packets with different extension header data do not coalesce
in GRO.

I changed the receive socket filter to accept a packet with one extension
header. This change exposed a bug in the fragment test -- the old BPF did
not accept the fragment packet. I updated correct_num_packets in the
fragment test accordingly.

05d92cb0e9 selftests/net: change shebang to bash to support "source"
The patch set [1] added a general lib.sh in net selftests, and converted
several test scripts to source the lib.sh.

unicast_extensions.sh (converted in [1]) and pmtu.sh (converted in [2])
have a /bin/sh shebang which may point to various shells in different
distributions, but "source" is only available in some of them. For
example, "source" is a built-it function in bash, but it cannot be
used in dash.

Refer to other scripts that were converted together, simply change the
shebang to bash to fix the following issues when the default /bin/sh
points to other shells.

not ok 51 selftests: net: unicast_extensions.sh # exit=1

v1 -> v2:
  - Fix pmtu.sh which has the same issue as unicast_extensions.sh,
    suggested by Hangbin
  - Change the style of the "source" line to be consistent with other
    tests, suggested by Hangbin

80057b2080 selftest/tcp-ao: Work on namespace-ified sysctl_optmem_max
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.

72cd9f8d5a selftest/tcp-ao: Set routes in a proper VRF table id
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.

2491d66ae6 selftests: forwarding: ethtool_mm: support devices with higher rx-min-frag-size
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.

826eb9bcc1 selftest/tcp-ao: Rectify out-of-tree build
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")

c8f021eec5 selftests: mptcp: join: fix subflow_send_ack lookup
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.

3c3ead5556 selftests/net: Add TCP-AO key-management test
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.

Sample output:

8c4e8dd0c0 selftests/net: Add TCP-AO selfconnect/simultaneous connect test
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:

c6df7b2361 selftests/net: Add TCP-AO RST test
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.

>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].

6f0c472a68 selftests/net: Add TCP-AO + TCP-MD5 + no sign listen socket tests
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

Output produced:

d11301f659 selftests/net: Add TCP-AO ICMPs accept test
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).
For the kernel error handlers see: tab_unreach[] and icmp_err_convert[].

cfbab37b3d selftests/net: Add TCP-AO library
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.

The reason is when CONFIG_IPV6_SUBTREES is not enabled, rt6_fill_node() will
not put RTA_SRC info. After fix:
