The removal of eprobes was broken and missed in testing. Add various ways
to remove eprobes that are considered acceptable to the testing process to
catch when/if they break again.

The output behavior for undefined bits is now directly tested inside the bash
script. Trying to set an undefined bit should be refused.
The input behavior for undefined bits has been removed due to the fact that we
would need another sender allowed to set undefined bits.

Problem:
What does this do?
$ kunit.py run --json
Well, it runs all the tests and prints test results out as JSON.
And next is
$ kunit.py run my-test-suite --json
This runs just `my-test-suite` and prints results out as JSON.
But what about?
$ kunit.py run --json my-test-suite
This runs all the tests and stores the json results in a "my-test-suite"
file.
Why:
--json, and now --raw_output are actually string flags. They just have a
default value. --json in particular takes the name of an output file.
It was intended that you'd do
$ kunit.py run --json=my_output_file my-test-suite
if you ever wanted to specify the value.
Workaround:
It doesn't seem like there's a way to make
https://docs.python.org/3/library/argparse.html only accept arg values
after a '='.
I believe that `--json` should "just work" regardless of where it is.
So this patch automatically rewrites a bare `--json` to `--json=stdout`.
That makes the examples above work the same way.
Add a regression test that can catch this for --raw_output.

Rework the CPU selection in the migration worker to ensure the specified
number of migrations are performed when the test iteslf is affined to a
subset of CPUs. The existing logic skips iterations if the target CPU is
not in the original set of possible CPUs, which causes the test to fail
if too many iterations are skipped.
==== Test Assertion Failure ====
rseq_test.c:228: i > (NR_TASK_MIGRATIONS / 2)
pid=10127 tid=10127 errno=4 - Interrupted system call
1 0x00000000004018e5: main at rseq_test.c:227
2 0x00007fcc8fc66bf6: ?? ??:0
3 0x0000000000401959: _start at ??:?
Only performed 4 KVM_RUNs, task stalled too much?
Calculate the min/max possible CPUs as a cheap "best effort" to avoid
high runtimes when the test is affined to a small percentage of CPUs.
Alternatively, a list or xarray of the possible CPUs could be used, but
even in a horrendously inefficient setup, such optimizations are not
needed because the runtime is completely dominated by the cost of
migrating the task, and the absolute runtime is well under a minute in
even truly absurd setups, e.g. running on a subset of vCPUs in a VM that
is heavily overcommited (16 vCPUs per pCPU).

It's not enough to set net.ipv4.conf.all.rp_filter=0, that does not override
a greater rp_filter value on the individual interfaces. We also need to set
net.ipv4.conf.default.rp_filter=0 before creating the interfaces. That way,
they'll also get their own rp_filter value of zero.

When building bpf selftest with make -j, I'm randomly getting build failures
such as this one:
In file included from progs/bpf_flow.c:19:
[...]/tools/testing/selftests/bpf/tools/include/bpf/bpf_helpers.h:11:10: fatal error: 'bpf_helper_defs.h' file not found
#include "bpf_helper_defs.h"
^~~~~~~~~~~~~~~~~~~
The file that fails the build varies between runs but it's always in the
progs/ subdir.
The reason is a missing make dependency on libbpf for the .o files in
progs/. There was a dependency before commit 3ac2e20fba07e but that commit
removed it to prevent unneeded rebuilds. However, that only works if libbpf
has been built already; the 'wildcard' prerequisite does not trigger when
there's no bpf_helper_defs.h generated yet.
Keep the libbpf as an order-only prerequisite to satisfy both goals. It is
always built before the progs/ objects but it does not trigger unnecessary
rebuilds by itself.

Pull arm64 fixes from Catalin Marinas:
- It turns out that the optimised string routines merged in 5.14 are
not safe with in-kernel MTE (KASAN_HW_TAGS) because of reading beyond
the end of a string (strcmp, strncmp). Such reading may go across a
16 byte tag granule and cause a tag check fault. When KASAN_HW_TAGS
is enabled, use the generic strcmp/strncmp C implementation.
- An errata workaround for ThunderX relied on the CPU capabilities
being enabled in a specific order. This disappeared with the
automatic generation of the cpucaps.h file (sorted alphabetically).
Fix it by checking the current CPU only rather than the system-wide
capability.
- Add system_supports_mte() checks on the kernel entry/exit path and
thread switching to avoid unnecessary barriers and function calls on
systems where MTE is not supported.
- kselftests: skip arm64 tests if the required features are missing.

Compiling the KVM selftests with clang emits the following warning:

>> return (unsigned long)xmm0;
where xmm0 is accessed via an uninitialized register variable.
Indeed, this is a misuse of register variables, which really should only
be used for specifying register constraints on variables passed to
inline assembly. Rather than attempting to read xmm registers via
register variables, just explicitly perform the movq from the desired
xmm register.

While x86 does not require any additional setup to use the ucall
infrastructure, arm64 needs to set up the MMIO address used to signal a
ucall to userspace. rseq_test does not initialize the MMIO address,
resulting in the test spinning indefinitely.
Fix the issue by calling ucall_init() during setup.

Test that if:
* L1 disables virtual interrupt masking, and INTR intercept.
* L1 setups a virtual interrupt to be injected to L2 and enters L2 with
interrupts disabled, thus the virtual interrupt is pending.
* Now an external interrupt arrives in L1 and since
L1 doesn't intercept it, it should be delivered to L2 when
it enables interrupts.
to do this L0 (abuses) V_IRQ to setup an
interrupt window, and returns to L2.
* L2 enables interrupts.
This should trigger the interrupt window,
injection of the external interrupt and delivery
of the virtual interrupt that can now be done.
* Test that now L2 gets those interrupts.
This is the test that demonstrates the issue that was
fixed in the previous patch.

All selftests that support the backing_src option were printing their
own description of the flag and then calling backing_src_help() to dump
the list of available backing sources. Consolidate the flag printing in
backing_src_help() to align indentation, reduce duplicated strings, and
improve consistency across tests.
Note: Passing "-s" to backing_src_help is unnecessary since every test
uses the same flag. However I decided to keep it for code readability
at the call sites.
While here this opportunistically fixes the incorrectly interleaved
printing -x help message and list of backing source types in
dirty_log_perf_test.

The SMC64 calling convention passes a function identifier in w0 and its
parameters in x1-x17. Given this, there are two deviations in the
SMC64 call performed by the steal_time test: the function identifier is
assigned to a 64 bit register and the parameter is only 32 bits wide.
Align the call with the SMCCC by using a 32 bit register to handle the
function identifier and increasing the parameter width to 64 bits.

for a bug introduced by commit 72c3c0fe54a3 ("x86/kvm: Use generic xfer

without updating rseq, leading to a stale CPU ID and other badness.

Add a script to exercise NAT port clash resolution with directional zones.
Add net namespaces that use the same IP address and connect them to a
gateway.
Gateway uses policy routing based on iif/mark and conntrack zones to
isolate the client namespaces. In server direction, same zone with NAT
to single address is used.
Then, connect to a server from each client netns, using identical
connection id, i.e. saddr:sport -> daddr:dport.
Expectation is for all connections to succeeed: NAT gatway is
supposed to do port reallocation for each of the (clashing) connections.
This is based on the description/use case provided in the commit message of
deedb59039f111 ("netfilter: nf_conntrack: add direction support for zones").

Makefile uses TEST_PROGS instead of TEST_GEN_PROGS to define
executables. TEST_PROGS is for shell scripts that need to be
installed and run by the common lib.mk framework. The common
framework doesn't touch TEST_PROGS when it does build and clean.
As a result "make kselftest-clean" and "make clean" fail to remove
executables. Run and install work because the common framework runs
and installs TEST_PROGS. Build works because the Makefile defines
"all" rule which is unnecessary if TEST_GEN_PROGS is used.
Use TEST_GEN_PROGS so the common framework can handle build/run/
install/clean properly.
