e35f885b35 selftests: mptcp: be more conservative with cookie MPJ limits
Since commit 2843ff6f36 ("mptcp: remote addresses fullmesh"), an
MPTCP client can attempt creating multiple MPJ subflow simultaneusly.

In such scenario the server, when syncookies are enabled, could end-up
accepting incoming MPJ syn even above the configured subflow limit, as
the such limit can be enforced in a reliable way only after the subflow
creation. In case of syncookie, only after the 3rd ack reception.

As a consequence the related self-tests case sporadically fails, as it
verify that the server always accept the expected number of MPJ syn.

Address the issues relaxing the MPJ syn number constrain. Note that the
check on the accepted number of MPJ 3rd ack still remains intact.

24720d7452 selftests: mptcp: add csum mib check for mptcp_connect

script mptcp_connect.sh when the data checksum is enabled.

In do_transfer(), got the mib counters twice, before and after running
the mptcp_connect commands. The latter minus the former is the actual
number of the data checksum mib counter.

The output looks like this:

ns1 MPTCP -> ns2 (10.0.2.1:10008      ) MPTCP   (duration    66ms) [ FAIL ]

d17b968b98 selftests: mptcp: increase timeout to 20 minutes
With the increase number of tests, one CI instance, using a debug kernel
config and not recent hardware, takes around 10 minutes to execute the
slowest MPTCP test: mptcp_join.sh.

Even if most CIs don't take that long to execute these tests --
typically max 10 minutes to run all selftests -- it will help some of
them if the timeout is increased.

The timeout could be disabled but it is always good to have an extra
safeguard, just in case.

Please note that on slow public CIs with kernel debug settings, it has
been observed it can easily take up to 45 minutes to execute all tests
in this very slow environment with other jobs running in parallel.
The slowest test, mptcp_join.sh takes ~30 minutes in this case.

In such environments, the selftests timeout set in the 'settings' file
is disabled because this environment is known as being exceptionnally
slow. It has been decided not to take such exceptional environments into
account and set the timeout to 20min.

4ddc844eb8 net/sched: act_police: more accurate MTU policing
in current Linux, MTU policing does not take into account that packets at
the TC ingress have the L2 header pulled. Thus, the same TC police action
(with the same value of tcfp_mtu) behaves differently for ingress/egress.
In addition, the full GSO size is compared to tcfp_mtu: as a consequence,
the policer drops GSO packets even when individual segments have the L2 +
L3 + L4 + payload length below the configured valued of tcfp_mtu.

Improve the accuracy of MTU policing as follows:
 - account for mac_len for non-GSO packets at TC ingress.
 - compare MTU threshold with the segmented size for GSO packets.
Also, add a kselftest that verifies the correct behavior.

IPv6 routes. Setting ->rtm_tos for IPv6 is thus invalid as the route
is going to work only on the destination address anyway, so it won't

Before this patch, IPv4 routes specifying an rtm_tos with some of the
ECN bits set were accepted. However they wouldn't work (never match) as
IPv4 normally clears the ECN bits with IPTOS_RT_MASK before doing a FIB
lookup (although a few buggy code paths don't).

After this patch, IPv4 routes specifying an rtm_tos with any ECN bit
set is rejected.

Note: IPv6 routes ignore rtm_tos altogether, any rtm_tos is accepted,
but treated as if it were 0.

563f8e97e0 ipv4: Stop taking ECN bits into account in fib4-rules
Use the new dscp_t type to replace the tos field of struct fib4_rule,
so that fib4-rules consistently ignore ECN bits.

Before this patch, fib4-rules did accept rules with the high order ECN
bit set (but not the low order one). Also, it relied on its callers
masking the ECN bits of ->flowi4_tos to prevent those from influencing
the result. This was brittle and a few call paths still do the lookup
without masking the ECN bits first.

After this patch fib4-rules only compare the DSCP bits. ECN can't
influence the result anymore, even if the caller didn't mask these
bits. Also, fib4-rules now must have both ECN bits cleared or they will
be rejected.

a410a0cf98 ipv6: Define dscp_t and stop taking ECN bits into account in fib6-rules
Define a dscp_t type and its appropriate helpers that ensure ECN bits
are not taken into account when handling DSCP.

Use this new type to replace the tclass field of struct fib6_rule, so
that fib6-rules don't get influenced by ECN bits anymore.

Before this patch, fib6-rules didn't make any distinction between the
DSCP and ECN bits. Therefore, rules specifying a DSCP (tos or dsfield
options in iproute2) stopped working as soon a packets had at least one
of its ECN bits set (as a work around one could create four rules for
each DSCP value to match, one for each possible ECN value).

After this patch fib6-rules only compare the DSCP bits. ECN doesn't
influence the result anymore. Also, fib6-rules now must have the ECN
bits cleared or they will be rejected.

f014038625 selftests: mptcp: add wrapper for setting flags
This patch implemented a new function named pm_nl_set_endpoint(), wrapped
the PM netlink commands 'ip mptcp endpoint change flags' and 'pm_nl_ctl
set flags' in it, and used a new argument 'ip_mptcp' to choose which one
to use to set the flags of the PM endpoint.

'ip mptcp' used the ID number argument to find out the address to change
flags, while 'pm_nl_ctl' used the address and port number arguments. So
we need to parse the address ID from the PM dump output as well as the
address and port number.

Used this wrapper in do_transfer() instead of using the pm_nl_ctl command
directly.

This patch implemented a new function named pm_nl_show_endpoints(), wrapped
the PM netlink commands 'ip mptcp endpoint show' and 'pm_nl_ctl dump' in
it, used a new argument 'ip_mptcp' to choose which one to use to show all
the PM endpoints.

Used this wrapper in do_transfer() instead of using the pm_nl_ctl commands
directly.

The original 'pos+=5' in the remoing tests only works for the output of
'pm_nl_ctl show':

  id 1 flags subflow 10.0.1.1

It doesn't work for the output of 'ip mptcp endpoint show':

  10.0.1.1 id 1 subflow

So implemented a more flexible approach to get the address ID from the PM
dump output to fit for both commands.

This patch added the backup testcase using an address with a port number.

The original backup tests only work for the output of 'pm_nl_ctl dump'
without the port number. It chooses the last item in the dump to parse
the address in it, and in this case, the address is showed at the end
of the item.

But it doesn't work for the dump with the port number, in this case, the
port number is showed at the end of the item, not the address.

So implemented a more flexible approach to get the address and the port
number from the dump to fit for the port number case.

95eb6ef82b selftests: rtnetlink: Use more sensible tos values
Using tos 0x1 with 'ip route get <IPv4 address> ...' doesn't test much
of the tos option handling: 0x1 just sets an ECN bit, which is cleared
by inet_rtm_getroute() before doing the fib lookup. Let's use 0x10
instead, which is actually taken into account in the route lookup (and
is less surprising for the reader).

For consistency, use 0x10 for the IPv6 route lookup too (IPv6 currently
doesn't clear ECN bits, but might do so in the future).

bafe517af2 selftests: fib offload: use sensible tos values
Although both iproute2 and the kernel accept 1 and 2 as tos values for
new routes, those are invalid. These values only set ECN bits, which
are ignored during IPv4 fib lookups. Therefore, no packet can actually
match such routes. This selftest therefore only succeeds because it
doesn't verify that the new routes do actually work in practice (it
just checks if the routes are offloaded or not).

It makes more sense to use tos values that don't conflict with ECN.
This way, the selftest won't be affected if we later decide to warn or
even reject invalid tos configurations for new routes.
