The patch fdb8e12cc2cc ("netfilter: ipset: fix performance regression
in swap operation") missed to add the calls to gc cancellations
at the error path of create operations and at module unload. Also,
because the half of the destroy operations now executed by a
function registered by call_rcu(), neither NFNL_SUBSYS_IPSET mutex
or rcu read lock is held and therefore the checking of them results
false warnings.

If hv_netvsc driver is unloaded and reloaded, the NET_DEVICE_REGISTER
handler cannot perform VF register successfully as the register call
is received before netvsc_probe is finished. This is because we
register register_netdevice_notifier() very early( even before
vmbus_driver_register()).
To fix this, we try to register each such matching VF( if it is visible
as a netdevice) at the end of netvsc_probe.

For XDP_TX action xdp_buff is converted to xdp_frame. The conversion is
done by xdp_convert_buff_to_frame(). The memory type of the resulting
xdp_frame depends on the memory type of the xdp_buff. For page pool
based xdp_buff it produces xdp_frame with memory type
MEM_TYPE_PAGE_POOL. For zero copy XSK pool based xdp_buff it produces
xdp_frame with memory type MEM_TYPE_PAGE_ORDER0.

tsnep_xdp_xmit_back() is not prepared for that and uses always the page
pool buffer type TSNEP_TX_TYPE_XDP_TX. This leads to invalid mappings
and the transmission of undefined data.

Improve tsnep_xdp_xmit_back() to use the generic buffer type
TSNEP_TX_TYPE_XDP_NDO for zero copy XDP_TX.

Using hard-coded constant timeout to wait for some expected
event is deemed to fail sooner or later, especially in slow
env.

Our CI has spotted another of such race:
   # TEST: ipv6: cleanup of cached exceptions - nexthop objects          [FAIL]
   #   can't delete veth device in a timely manner, PMTU dst likely leaked

Replace the crude sleep with a loop looking for the expected condition
at low interval for a much longer range.

The pmtu.sh test uses a few TCP listener in a problematic way:
It hard-codes a constant timeout to wait for the listener starting-up
in background. That introduces unneeded latency and on very slow and
busy host it can fail.

Additionally the test starts again the same listener in the same
namespace on the same port, just after the previous connection
completed. Fast host can attempt starting the new server before the
old one really closed the socket.

Address the issues using the wait_local_port_listen helper and
explicitly waiting for the background listener process exit.

 "The current exception handler, which helps on kernel accesses to

  then will lead to silent register- and data corruption. To fix this
  issue we now use another strategy to help the exception handler to
  always find and set the error code into the correct CPU register.

In the arm random config file, kconfig option 'CONFIG_AEABI' is
disabled which results in adding the compiler flag '-mabi=apcs-gnu'.
This causes the compiler to add padding in virtchnl2_ptype
structure to align it to 8 bytes, resulting in the following
size check failure:

include/linux/build_bug.h:78:41: error: static assertion failed: "(6) == sizeof(struct virtchnl2_ptype)"
      78 | #define __static_assert(expr, msg, ...) _Static_assert(expr, msg)

Avoid the compiler padding by using "__packed" structure
attribute for the virtchnl2_ptype struct. Also align the
structure by using "__aligned(2)" for better code optimization.

mptcp: fixes for recent issues reported by CI's

This series of 9 patches fixes issues mostly identified by CI's not
managed by the MPTCP maintainers. Thank you Linero (LKFT) and Netdev
maintainers (NIPA) for running our kunit and selftests tests!

For the first patch, it took a bit of time to identify the root cause.
Some MPTCP Join selftest subtests have been "flaky", mostly in slow
environments. It appears to be due to the use of a TCP-specific helper
on an MPTCP socket. A fix for kernels >= v5.15.

Patches 2 to 4 add missing kernel config to support NetFilter tables
needed for IPTables commands. These kconfigs are usually enabled in
default configurations, but apparently not for all architectures.
Patches 2 and 3 can be backported up to v5.11 and the 4th one up to
v5.19.

Patch 5 increases the time limit for MPTCP selftests. It appears that
many CI's execute tests in a VM without acceleration supports, e.g. QEmu
without KVM. As a result, the tests take longer. Plus, there are more
and more tests. This patch modifies the timeout added in v5.18.

Patch 6 reduces the maximum rate and delay of the different links in
some Simult Flows selftest subtests. The goal is to let slow VMs reach
the maximum speed. The original rate was introduced in v5.11.

Patch 7 lets CI changing the prefix of the subtests titles, to be able
to run the same selftest multiple times with different parameters. With
different titles, tests will be considered as different and not override
previous results as it is the case with some CI envs. Subtests have been
introduced in v6.6.

Patch 8 and 9 make some MPTCP Join selftest subtests quicker by stopping
the transfer when the expected events have been seen. Patch 8 can be
backported up to v6.5.

Since the "Fixes" commits mentioned below, the newly added "userspace
pm" subtests of mptcp_join selftests are launching the whole transfer in
the background, do the required checks, then wait for the end of
transfer.

There is no need to wait longer, especially because the checks at the
end of the transfer are ignored (which is fine). This saves quite a few
seconds on slow environments.

While at it, use 'mptcp_lib_kill_wait()' helper everywhere, instead of
on a specific one with 'kill_tests_wait()'.

If a CI executes the same selftest multiple times with different
options, all results from the same subtests will have the same title,
which confuse the CI. With the same title printed in TAP, the tests are
considered as the same ones.

Now, it is possible to override this prefix by using MPTCP_LIB_KSFT_TEST
env var, and have a different title.

While at it, use 'basename' to remove the suffix as well instead of
using an extra 'sed'.
