====================
netfilter: conntrack and nf_tables bug fixes
The following patchset contains netfilter fixes for net.
Broken since 5.19:
A few ancient connection tracking helpers assume TCP packets cannot
exceed 64kb in size, but this isn't the case anymore with 5.19 when
BIG TCP got merged, from myself.
Regressions since 5.19:
1. 'conntrack -E expect' won't display anything because nfnetlink failed
to enable events for expectations, only for normal conntrack events.
2. partially revert change that added resched calls to a function that can
be in atomic context. Both broken and fixed up by myself.
Broken for several releases (up to original merge of nf_tables):
Several fixes for nf_tables control plane, from Pablo.
This fixes up resource leaks in error paths and adds more sanity
checks for mutually exclusive attributes/flags.
Kconfig:
NF_CONNTRACK_PROCFS is very old and doesn't provide all info provided
via ctnetlink, so it should not default to y. From Geert Uytterhoeven.
Selftests:
rework nft_flowtable.sh: it frequently indicated failure; the way it
tried to detect an offload failure did not work reliably.
* git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf:
testing: selftests: nft_flowtable.sh: rework test to detect offload failure

netfilter: nf_tables: check NFT_SET_CONCAT flag if field_count is specified

This test fails on current kernel releases because the flotwable path
now calls dst_check from packet path and will then remove the offload.
Test script has two purposes:
1. check that file (random content) can be sent to other netns (and vv)
2. check that the flow is offloaded (rather than handled by classic
forwarding path).
Since dst_check is in place, 2) fails because the nftables ruleset in
router namespace 1 intentionally blocks traffic under the assumption
that packets are not passed via classic path at all.
Rework this: Instead of blocking traffic, create two named counters, one
for original and one for reverse direction.
The first three test cases are handled by classic forwarding path
(path mtu discovery is disabled and packets exceed MTU).
But all other tests enable PMTUD, so the originator and responder are
expected to lower packet size and flowtable is expected to do the packet
forwarding.
For those tests, check that the packet counters (which are only
incremented for packets that are passed up to classic forward path)
are significantly lower than the file size transferred.
I've tested that the counter-checks fail as expected when the 'flow add'
statement is removed from the ruleset.

"ns1" is a too generic name, use a random suffix to avoid
errors when such a netns exists. Also allows to run multiple
instances of the script in parallel.

...
This is a prelude to adding more tests to shell tests and in order to
support putting those tests into subdirectories, I need to change the
test code that scans/finds and runs them.
To support subdirs I have to recurse so it's time to refactor the code
to allow this and centralize the shell script finding into one location
and only one single scan that builds a list of all the found tests in
memory instead of it being duplicated in 3 places.
This code also optimizes things like knowing the max width of desciption
strings (as we can do that while we scan instead of a whole new pass of
opening files).
It also more cleanly filters scripts to see only *.sh files thus
skipping random other files in directories like *~ backup files, other
random junk/data files that may appear and the scripts must be
executable to make the cut (this ensures the script lib dir is not seen
as scripts to run).
This avoids perf test running previous older versions of test scripts
that are editor backup files as well as skipping perf.data files that
may appear and so on.

If a shorter string ends a longer string then the shorter string may
reuse the longer string at an offset. For example, on x86 the event
arith.cycles_div_busy and cycles_div_busy can be folded, even though
they have difference names the strings are identical after 6
characters. cycles_div_busy can reuse the arith.cycles_div_busy string
at an offset of 6.
In pmu-events.c this looks like the following where the 'also:' lists
folded strings:
/* offset=177541 */ "arith.cycles_div_busy\000\000pipeline\000Cycles the divider is busy\000\000\000event=0x14,period=2000000,umask=0x1\000\000\000\000\000\000\000\000\000" /* also: cycles_div_busy\000\000pipeline\000Cycles the divider is busy\000\000\000event=0x14,period=2000000,umask=0x1\000\000\000\000\000\000\000\000\000 */
As jevents.py combines multiple strings for an event into a larger
string, the amount of folding is minimal as all parts of the event must
align. Other organizations can benefit more from folding, but lose space
by say recording more offsets.

The pmu_events array requires 15 pointers per entry which in position
independent code need relocating. Change the array to be an array of
offsets within a big C string. Only the offset of the first variable is
required, subsequent variables are stored in order after the \0
terminator (requiring a byte per variable rather than 4 bytes per
offset).
The file size savings are:
no jevents - the same 19,788,464bytes
x86 jevents - ~16.7% file size saving 23,744,288bytes vs 28,502,632bytes
all jevents - ~19.5% file size saving 24,469,056bytes vs 30,379,920bytes
default build options plus NO_LIBBFD=1.
For example, the x86 build savings come from .rela.dyn and
.data.rel.ro becoming smaller by 3,157,032bytes and 3,042,016bytes
respectively. .rodata increases by 1,432,448bytes, giving an overall
4,766,600bytes saving.
To make metric strings more shareable, the topic is changed from say
'skx metrics' to just 'metrics'.
To try to help with the memory layout the pmu_events are ordered as used
by perf qsort comparator functions.

The current code assumes that a struct pmu_event can be iterated over
forward until a NULL pmu_event is encountered.
This makes it difficult to refactor pmu_event.
Add a loop function taking a callback function that's passed the struct
pmu_event.
This way the pmu_event is only needed for one element and not an entire
array.
Switch existing code iterating over the pmu_event arrays to use the new
loop function pmu_events_table_for_each_event.

Preparation for hiding pmu_events_map as an implementation detail. While
the map is passed, the table of events is all that is normally wanted.
While modifying the function's types, rename pmu_events_map__find to
pmu_events_table__find to match later encapsulation. Similarly rename
pmu_add_cpu_aliases_map to pmu_add_cpu_aliases_table.

Sort the JSON files entries on conversion to C. The sort order tries to
replicated cmp_sevent from pmu.c so that the input there is already
sorted except for sysfs events. Specifically, the sort order is given by
the tuple:
(not j.desc is None, fix_none(j.topic), fix_none(j.name), fix_none(j.pmu), fix_none(j.metric_name))
which is putting events with descriptions and topics before those
without, then sorting by name, then pmu and finally metric_name
Add the topic to JsonEvent on reading to simplify. Remove an unnecessary
lambda in the JSON reading.

pmu_events_map has a type variable that is always initialized to "core"
and a version variable that is never read. Remove these from the API as
it is straightforward to add them back when necessary.

When 'all' is passed as the architecture generate a mapping table for
all architectures. This simplifies testing. To identify the table for an
architecture add an arch variable to the pmu_events_map.

There's still a handful of new features in here, but there are a lot of
fixes/cleanups as well:
* Support for the Zicbom for explicit cache-block management, along with
the necessary bits to make the non-standard cache management ops on
the Allwinner D1 function.
* Support for the Zihintpause extension, which codifies a go-slow
instruction used for cpu_relax().
* Support for the Sstc extension for supervisor-mode timer/counter
management.
* Many device tree fixes and cleanups, including a large set for the
Canaan device trees.
* A handful of fixes and cleanups for the PMU driver.

When the CONFIG_PORTABLE/CONFIG_NONPORTABLE switches were added, various
configs were updated, but the wireguard config was forgotten about. This
leads to unbootable test kernels, causing CI fails. Add
CONFIG_NONPORTABLE=y to the wireguard test suite configuration for
riscv32.

Since Arm64 arch doesn't support HITMs flags, this patch changes to use
'peer' as default display if user doesn't specify any type; for other
arches, it still uses 'tot' as default display type if user doesn't
specify it.
This patch changes to call perf_session__new() in an earlier place, so
session environment can be initialized ahead and arch info can be used
for setting display type.
