61d9658050 selftests: mptcp: pm_nl_ctl: fix 32-bit support
When using pm_nl_ctl to validate userspace path-manager's behaviours, it
was failing on 32-bit architectures ~half of the time.

pm_nl_ctl was not reporting any error but the command was not doing what
it was expected to do. As a result, the expected linked event was not
triggered after and the test failed.

This is due to the fact the token given in argument to the application
was parsed as an integer with atoi(): in a 32-bit arch, if the number
was bigger than INT_MAX, 2147483647 was used instead.

This can simply be fixed by using strtoul() instead of atoi().

The errors have been seen "by chance" when manually looking at the
results from LKFT.

6c8880fcaa selftests: mptcp: depend on SYN_COOKIES
MPTCP selftests are using TCP SYN Cookies for quite a while now, since
v5.9.

Some CIs don't have this config option enabled and this is causing
issues in the tests:

  # ns1 MPTCP -> ns1 (10.0.1.1:10000      ) MPTCP     (duration   167ms) sysctl: cannot stat /proc/sys/net/ipv4/tcp_syncookies: No such file or directory
  # [ OK ]./mptcp_connect.sh: line 554: [: -eq: unary operator expected

There is no impact in the results but the test is not doing what it is
supposed to do.

9ac4c28eb7 selftests: mptcp: sockopt: return error if wrong mark
When an error was detected when checking the marks, a message was
correctly printed mentioning the error but followed by another one
saying everything was OK and the selftest was not marked as failed as
expected.

Now the 'ret' variable is directly set to 1 in order to make sure the
exit is done with an error, similar to what is done in other functions.
While at it, the error is correctly propagated to the caller.

221e455045 selftests: mptcp: connect: fail if nft supposed to work
In case of "external" errors when preparing the environment for the
TProxy tests, the subtests were marked as skipped.

This is fine but it means these errors are ignored. On MPTCP Public CI,
we do want to catch such issues and mark the selftest as failed if there
are such issues. We can then use mptcp_lib_fail_if_expected_feature()
helper that has been recently added to fail if needed.

This is because IPsec "policy" match support is not available

This patch adds CONFIG_NETFILTER_XT_MATCH_POLICY as a module
to the selftests/net/config file, so that `make
kselftest-merge` can take this into consideration.

This patch makes chk_mptcp_info() more generic to be able to check
subflows, add_addr_signal and add_addr_accepted info (and even more
later). New arguments are now required to get different infos from the
two namespaces because some counters are specific to the client or the
server.

c7c059fba6 selftests: forwarding: Fix race condition in mirror installation
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.

00079f18c2 selftests: mptcp: join: skip check if MIB counter not supported (part 2)
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.

5e71bf50c2 selftests: forwarding: router_bridge: Use port MAC for bridge address
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 here.

These two selftests however check mirroring traffic to a gretap netdevice.
The bridge here does not participate in routing traffic and the IP address
or the RIF are irrelevant.

Fix by disabling automatic IPv6 address generation for the HW-offloaded
bridges in these selftests, thus exempting them from mlxsw router
attention. Since the bridges are only used for L2 forwarding, this change
should not hinder usefulness of this selftest for testing SW datapath or HW
datapaths in other devices.

f61018dc3e selftests: forwarding: pedit_dsfield: Disable IPv6 autogen on a bridge
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 selftest itself however checks whether skbedit changes packet priority
as appropriate. The bridge thus does not need to participate in routing
traffic and the IP address or the RIF are irrelevant.

Fix by disabling automatic IPv6 address generation for the HW-offloaded
bridge in this selftest, thus exempting it from mlxsw router attention.
Since the bridge is only used for L2 forwarding, this change should not
hinder usefulness of this selftest for testing SW datapath or HW datapaths
in other devices.

bef68e201e selftests: forwarding: hw_stats_l3: Set addrgenmode in a separate step
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.

Selftests are supposed to run on any kernels, including the old ones not

One of them is the support of a mix of subflows in v4 and v6 by the
in-kernel PM introduced by commit b9d69db87f ("mptcp: let the
in-kernel PM use mixed IPv4 and IPv6 addresses").

It looks like there is no external sign we can use to predict the
expected behaviour. Instead of accepting different behaviours and thus
not really checking for the expected behaviour, we are looking here for
a specific kernel version. That's not ideal but it looks better than
removing the test because it cannot support older kernel versions.

Commit bccefb7624 ("selftests: mptcp: simplify pm_nl_change_endpoint")
has simplified the way the backup flag is set on an endpoint. Instead of
doing:

  ./pm_nl_ctl set 10.0.2.1 flags backup

Now we do:

  ./pm_nl_ctl set id 1 flags backup

The new way is easier to maintain but it is also incompatible with older
kernels not supporting the implicit endpoints putting in place the
infrastructure to set flags per ID, hence the second Fixes tag.

Note that here and in the following commits, we re-do the same check for
each sub-test of the same function for a few reasons. The main one is
not to break the ID assign to each test in order to be able to easily
compare results between different kernel versions. Also, we can still
run a specific test even if it is skipped. Another reason is that it
makes it clear during the review that a specific subtest will be skipped
or not under certain conditions. At the end, it looks OK to call the
exact same helper multiple times: it is not a critical path and it is
the same code that is executed, not really more cases to maintain.

Selftests are supposed to run on any kernels, including the old ones not

Some tests are using IPTables and/or TC commands to force some
behaviours. If one of these commands fails -- likely because some
features are not available due to missing kernel config -- we should
intercept the error and skip the tests requiring these features.

Note that if we expect to have these features available and if
SELFTESTS_MPTCP_LIB_EXPECT_ALL_FEATURES env var is set to 1, the tests
will be marked as failed instead of skipped.

This patch also replaces the 'exit 1' by 'return 1' not to stop the
selftest in the middle without the conclusion if there is an issue with
NF or TC.
