x86/hyperv: Cosmetic changes for hv_apic.c
If the network configuration strings are passed as a combination of IPv4
and IPv6 addresses, the current KVP daemon does not handle processing for
the keyfile configuration format.
With these changes, the keyfile config generation logic scans through the
list twice to generate IPv4 and IPv6 sections for the configuration files
to handle this support.
Testcases ran:Rhel 9, Hyper-V VMs
(IPv4 only, IPv6 only, IPv4 and IPv6 combination)

Running turbostat on a 16 socket HPE Scale-up Compute 3200 (SapphireRapids) fails with:
turbostat: /sys/devices/system/cpu/intel_uncore_frequency/package_010_die_00/current_freq_khz: open failed: No such file or directory
We observe the sysfs uncore frequency directories named:
...
package_09_die_00/
package_10_die_00/
package_11_die_00/
...
package_15_die_00/
The culprit is an incorrect sprintf format string "package_0%d_die_0%d" used
with each instance of reading uncore frequency files. uncore-frequency-common.c
creates the sysfs directory with the format "package_%02d_die_%02d". Once the
package value reaches double digits, the formats diverge.
Change each instance of "package_0%d_die_0%d" to "package_%02d_die_%02d".

There's a bug in pm_nl_check_endpoint(), 'dev' didn't be parsed correctly.
If calling it in the 2nd test of endpoint_tests() too, it fails with an
error like this:
creation [FAIL] expected '10.0.2.2 id 2 subflow dev dev' \
found '10.0.2.2 id 2 subflow dev ns2eth2'
The reason is '$2' should be set to 'dev', not '$1'. This patch fixes it.

Current MPTCP servers increment MPTcpExtMPCapableFallbackACK when they
accept non-MPC connections. As reported by Christoph, this is "surprising"
because the counter might become greater than MPTcpExtMPCapableSYNRX.
MPTcpExtMPCapableFallbackACK counter's name suggests it should only be
incremented when a connection was seen using MPTCP options, then a
fallback to TCP has been done. Let's do that by incrementing it when
the subflow context of an inbound MPC connection attempt is dropped.
Also, update mptcp_connect.sh kselftest, to ensure that the
above MIB does not increment in case a pure TCP client connects to a
MPTCP server.

This patch adds two tests using SO_REUSEADDR and SO_REUSEPORT and
defines errno for each test case.
SO_REUSEADDR/SO_REUSEPORT is set for the per-fixture two bind()
calls.
The notable pattern is the pair of v6only [::] and plain [::].
The two sockets are put into the same tb2, where per-bucket v6only
flag would be useless to detect bind() conflict.

Currently, bind_wildcard.c calls bind() twice for two addresses and
checks the pre-defined errno against the 2nd call. Also, the two
bind() calls are swapped to cover various patterns how bind buckets
are created.
However, only testing two addresses is insufficient to detect regression.
So, we will add more bind() calls, and then, we need to define different
errno for each bind() per test case.
As a prepartion, let's define the reverse order bind() test cases as
fixtures.

The seccomp benchmark runs five scenarios, one calibration run with no
seccomp filters enabled then four further runs each adding a filter. The
calibration run times itself for 15s and then each additional run executes
for the same number of times.
Currently the seccomp tests, including the benchmark, run with an extended
120s timeout but this is not sufficient to robustly run the tests on a lot
of platforms. Sample timings from some recent runs:
Platform Run 1 Run 2 Run 3 Run 4
--------- ----- ----- ----- -----
PowerEdge R200 16.6s 16.6s 31.6s 37.4s
BBB (arm) 20.4s 20.4s 54.5s
Synquacer (arm64) 20.7s 23.7s 40.3s
The x86 runs from the PowerEdge are quite marginal and routinely fail, for
the successful run reported here the timed portions of the run are at
117.2s leaving less than 3s of margin which is frequently breached. The
added overhead of adding filters on the other platforms is such that there
is no prospect of their runs fitting into the 120s timeout, especially
on 32 bit arm where there is no BPF JIT.
While we could lower the time we calibrate for I'm also already seeing the
currently completing runs reporting issues with the per filter overheads
not matching expectations:
Let's instead raise the timeout to 180s which is only a 50% increase on the
current timeout which is itself not *too* large given that there's only two
tests in this suite.

The event filter function test has been failing in our internal test
farm:
| # not ok 33 event filter function - test event filtering on functions
Running the test in verbose mode indicates that this is because the test
erroneously determines that kmem_cache_free() is the most common caller
of kmem_cache_free():
# # + cut -d: -f3 trace
# # + sed s/call_site=([^+]*)+0x.*/1/
# # + sort
# # + uniq -c
# # + sort
# # + tail -n 1
# # + sed s/^[ 0-9]*//
# # + target_func=kmem_cache_free
... and as kmem_cache_free() doesn't call itself, setting this as the
filter function for kmem_cache_free() results in no hits, and
consequently the test fails:
# # + grep kmem_cache_free trace
# # + grep kmem_cache_free
# # + wc -l
# # + hitcnt=0
# # + grep kmem_cache_free trace
# # + grep -v kmem_cache_free
# # + wc -l
# # + misscnt=0
# # + [ 0 -eq 0 ]
# # + exit_fail
This seems to be because the system in question has tasks with ':' in
their name (which a number of kernel worker threads have). These show up
in the trace, e.g.
test:.sh-1299 [004] ..... 2886.040608: kmem_cache_free: call_site=putname+0xa4/0xc8 ptr=000000000f4d22f4 name=names_cache
... and so when we try to extact the call_site with:
cut -d: -f3 trace | sed 's/call_site=\([^+]*\)+0x.*/\1/'
... the 'cut' command will extrace the column containing
'kmem_cache_free' rather than the column containing 'call_site=...', and
the 'sed' command will leave this unchanged. Consequently, the test will
decide to use 'kmem_cache_free' as the filter function, resulting in the
failure seen above.
Fix this by matching the 'call_site=<func>' part specifically to extract
the function name.
