41b9fb381a Including fixes from netfilter.
As Paolo promised we continue to hammer out issues in our selftests.
 This is not the end but probably the peak.
 
 Current release - regressions:
 
  - smc: fix incorrect SMC-D link group matching logic
 
 Current release - new code bugs:
 
  - eth: bnxt: silence WARN() when device skips a timestamp, it happens
 
 Previous releases - regressions:
 
  - ipmr: fix null-deref when forwarding mcast packets
 
  - conntrack: evaluate window negotiation only for packets in the REPLY
    direction, otherwise SYN retransmissions trigger incorrect window
    scale negotiation
 
  - ipset: fix performance regression in swap operation
 
 Previous releases - always broken:
 
  - tcp: add sanity checks to types of pages getting into
    the rx zerocopy path, we only support basic NIC -> user,
    no page cache pages etc.
 
  - ip6_tunnel: make sure to pull inner header in __ip6_tnl_rcv()
 
  - nt_tables: more input sanitization changes
 
  - dsa: mt7530: fix 10M/100M speed on MediaTek MT7988 switch
 
  - bridge: mcast: fix loss of snooping after long uptime,
    jiffies do wrap on 32bit
 
  - xen-netback: properly sync TX responses, protect with locking

04b57c9e09 selftests: mptcp: join: stop transfer when check is done (part 2)
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()'.

de46d138e7 selftests: mptcp: allow changing subtests prefix
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'.

5e2f3c65af selftests: mptcp: decrease BW in simult flows
When running the simult_flow selftest in slow environments -- e.g. QEmu
without KVM support --, the results can be unstable. This selftest
checks if the aggregated bandwidth is (almost) fully used as expected.

To help improving the stability while still keeping the same validation
in place, the BW and the delay are reduced to lower the pressure on the
CPU.

4d4dfb2019 selftests: mptcp: increase timeout to 30 min
On very slow environments -- e.g. when QEmu is used without KVM --,
mptcp_join.sh selftest can take a bit more than 20 minutes. Bump the
default timeout by 50% as it seems normal to take that long on some
environments.

When a debug kernel config is used, this selftest will take even longer,
but that's certainly not a common test env to consider for the timeout.

The Fixes tag that has been picked here is there simply to help having
this patch backported to older stable versions. It is difficult to point
to the exact commit that made some env reaching the timeout from time to
time.

8cc063ae1b selftests: bonding: Check initial state
The purpose of the test_LAG_cleanup() function is to check that some
hardware addresses are removed from underlying devices after they have been
unenslaved. The test function simply checks that those addresses are not
present at the end. However, if the addresses were never added to begin
with due to some error in device setup, the test function currently passes.
This is a false positive since in that situation the test did not actually
exercise the intended functionality.

Add a check that the expected addresses are indeed present after device
setup. This makes the test function more robust.

I noticed this problem when running the team/dev_addr_lists.sh test on a
system without support for dummy and ipv6:

tools/testing/selftests/drivers/net/team# ./dev_addr_lists.sh
Error: Unknown device type.
Error: Unknown device type.

e4e4b6d568 selftests: net: fix available tunnels detection
The pmtu.sh test tries to detect the tunnel protocols available
in the running kernel and properly skip the unsupported cases.

In a few more complex setup, such detection is unsuccessful, as
the script currently ignores some intermediate error code at
setup time.

In order to rectify it, aim on TCP_TW_RST.
Doesn't seem way too good with this sleep() part, but it seems as
a reasonable compromise for the test. There is a plan in-line comment on
how-to improve it, going to do it on the top, at this moment I want it
to run on netdev/patchwork selftests dashboard.

384aa16d37 selftests/net: Rectify key counters checks
As the names of (struct test_key) members didn't reflect whether the key
was used for TX or RX, the verification for the counters was done
incorrectly for asymmetrical selftests.

Rename these with _tx appendix and fix checks in verify_counters().
While at it, as the checks are now correct, introduce skip_counters_checks,
which is intended for tests where it's expected that a key that was set
with setsockopt(sk, IPPROTO_TCP, TCP_AO_INFO, ...) might had no chance
of getting used on the wire.

Fixes the following failures, exposed by the previous commit:
> not ok 51 server: Check current != rnext keys set before connect(): Counter pkt_good was expected to increase 0 => 0 for key 132:5
> not ok 52 server: Check current != rnext keys set before connect(): Counter pkt_good was not expected to increase 0 => 21 for key 137:10

d8f5df1fce selftests/net: Argument value mismatch when calling verify_counters()
The end_server() function only operates in the server thread
and always takes an accept socket instead of a listen socket as
its input argument. To align with this, invert the boolean values
used when calling verify_counters() within the end_server() function.

As a result of this typo, the test didn't correctly check for
the non-symmetrical scenario, where i.e. peer-A uses a key <100:200>
to send data, but peer-B uses another key <105:205> to send its data.
So, in simple words, different keys for TX and RX.

b40f873a7c selftests: net: Add missing matchall classifier
One of the test cases in the test_bridge_backup_port.sh selftest relies
on a matchall classifier to drop unrelated traffic so that the Tx drop
counter on the VXLAN device will only be incremented as a result of
traffic generated by the test.

However, the configuration option for the matchall classifier is
missing from the configuration file which might explain the failures we
see in the netdev CI [1].

Fix by adding CONFIG_NET_CLS_MATCHALL to the configuration file.

b54761f6e9 kselftest/seccomp: Report each expectation we assert as a KTAP test
The seccomp benchmark test makes a number of checks on the performance it
measures and logs them to the output but does so in a custom format which
none of the automated test runners understand meaning that the chances that
anyone is paying attention are slim. Let's additionally log each result in
KTAP format so that automated systems parsing the test output will see each
comparison as a test case. The original logs are left in place since they
provide the actual numbers for analysis.

As part of this rework the flow for the main program so that when we skip
tests we still log all the tests we skip, this is because the standard KTAP
headers and footers include counts of the number of expected and run tests.

In preparation for trying to output the test results themselves in TAP
format rework all the prints in the benchmark to use the kselftest output
functions. The uses of system() all produce single line output so we can
avoid having to deal with fully managing the child process and continue to
use system() by simply printing an empty message before we invoke system().
We also leave one printf() used to complete a line of output in place.

f1fea725cc selftests/livepatch: fix and refactor new dmesg message code
The livepatching kselftests rely on comparing expected vs. observed
dmesg output.  After each test, new dmesg entries are determined by the
'comm' utility comparing a saved, pre-test copy of dmesg to post-test
dmesg output.

Alexander reports that the 'comm --nocheck-order -13' invocation used by
the tests can be confused when dmesg entry timestamps vary in magnitude
(ie, "[   98.820331]" vs. "[  100.031067]"), in which case, additional
messages are reported as new.  The unexpected entries then spoil the
test results.

Instead of relying on 'comm' or 'diff' to determine new testing dmesg
entries, refactor the code:

  - pre-test  : log a unique canary dmesg entry
  - test      : run tests, log messages
  - post-test : filter dmesg starting from pre-test message

d021b442cf selftests/mm: ksm_tests should only MADV_HUGEPAGE valid memory
ksm_tests was previously mmapping a region of memory, aligning the
returned pointer to a PMD boundary, then setting MADV_HUGEPAGE, but was
setting it past the end of the mmapped area due to not taking the pointer
alignment into consideration.  Fix this behaviour.

Up until commit efa7df3e3b ("mm: align larger anonymous mappings on THP
boundaries"), this buggy behavior was (usually) masked because the

52e63d67b5 selftests/mm: Update va_high_addr_switch.sh to check CPU for la57 flag
In order for the page table level 5 to be in use, the CPU must have the
setting enabled in addition to the CONFIG option. Check for the flag to be
set to avoid false test failures on systems that do not have this cpu flag
set.

The test does a series of mmap calls including three using the
MAP_FIXED flag and specifying an address that is 1<<47 or 1<<48.  These
addresses are only available if you are using level 5 page tables,
which requires both the CPU to have the capabiltiy (la57 flag) and the
kernel to be configured.  Currently the test only checks for the kernel
configuration option, so this test can still report a false positive. 
Here are the three failing lines:

$ ./va_high_addr_switch | grep FAILED
mmap(ADDR_SWITCH_HINT, 2 * PAGE_SIZE, MAP_FIXED): 0xffffffffffffffff - FAILED
mmap(HIGH_ADDR, MAP_FIXED): 0xffffffffffffffff - FAILED
mmap(ADDR_SWITCH_HINT, 2 * PAGE_SIZE, MAP_FIXED): 0xffffffffffffffff - FAILED

I thought (for about a second) refactoring the test so that these three
mmap calls will only be run on systems with the level 5 page tables
available, but the whole point of the test is to check the level 5
feature...

91b80cc5b3 selftests: mm: fix map_hugetlb failure on 64K page size systems
On systems with 64k page size and 512M huge page sizes, the allocation and
test succeeds but errors out at the munmap.  As the comment states, munmap
will failure if its not HUGEPAGE aligned.  This is due to the length of
the mapping being 1/2 the size of the hugepage causing the munmap to not
be hugepage aligned.  Fix this by making the mapping length the full
hugepage if the hugepage is larger than the length of the mapping.
