This patch adds support for verifying that we correctly handle the
situation where something is already mapped before the destination of the remap.
Any realignment of destination address and PMD-copy will destroy that
existing mapping. In such cases, we need to avoid doing the optimization.
To test this, we map an area called the preamble before the remap
region. Then we verify after the mremap operation that this region did not get
corrupted.
Putting some prints in the kernel, I verified that we optimize
correctly in different situations:
Optimize when there is alignment and no previous mapping (this is tested
by previous patch).
<prints>
can_align_down(old_vma->vm_start=2900000, old_addr=2900000, mask=-2097152): 0
can_align_down(new_vma->vm_start=2f00000, new_addr=2f00000, mask=-2097152): 0
=== Starting move_page_tables ===
Doing PUD move for 2800000 -> 2e00000 of extent=200000 <-- Optimization
Doing PUD move for 2a00000 -> 3000000 of extent=200000
Doing PUD move for 2c00000 -> 3200000 of extent=200000
</prints>
Don't optimize when there is alignment but there is previous mapping
(this is tested by this patch).
Notice that can_align_down() returns 1 for the destination mapping
as we detected there is something there.

This patch adds a test case to reproduce the SCTP DATA chunk retransmission
timeout issue caused by the improper SCTP collision processing in netfilter
nf_conntrack_proto_sctp.
In this test, client sends a INIT chunk, but the INIT_ACK replied from
server is delayed until the server sends a INIT chunk to start a new
connection from its side. After the connection is complete from server
side, the delayed INIT_ACK arrives in nf_conntrack_proto_sctp.
The delayed INIT_ACK should be dropped in nf_conntrack_proto_sctp instead
of updating the vtag with the out-of-date init_tag, otherwise, the vtag
in DATA chunks later sent by client don't match the vtag in the conntrack
entry and the DATA chunks get dropped.

Here is how it works:
* fault and fill the stack from RSP with INT3 down until rlimit allows,
* fill upwards with INT3 too, overwrite libc stuff, argv, envp,
* try to exec INT3 on each page and catch it in either SIGSEGV or
SIGTRAP handler.
Note: trying to execute _every_ INT3 on a 8 MiB stack takes 30-40 seconds
even on fast machine which is too much for kernel selftesting
(not for LTP!) so only 1 INT3 per page is tried.
Tested on F37 kernel and on a custom kernel which does:
vm_flags |= VM_EXEC;
to stack VMA.

The lkdtm selftest config fragment enables CONFIG_UBSAN_TRAP to make the
ARRAY_BOUNDS test kill the calling process when an out-of-bound access
is detected by UBSAN. However, after this [1] commit, UBSAN is triggered
under many new scenarios that weren't detected before, such as in struct
definitions with fixed-size trailing arrays used as flexible arrays. As
a result, CONFIG_UBSAN_TRAP=y has become a very aggressive option to
enable except for specific situations.
`make kselftest-merge` applies CONFIG_UBSAN_TRAP=y to the kernel config
for all selftests, which makes many of them fail because of system hangs
during boot.
This change removes the config option from the lkdtm kselftest and
configures the ARRAY_BOUNDS test to look for UBSAN reports rather than
relying on the calling process being killed.

Upon a panic() the kernel will use either smp_send_stop() or
crash_smp_send_stop() to attempt to stop secondary CPUs via an IPI,
which may or may not be an NMI. Generally it's preferable that this is an
NMI so that CPUs can be stopped in as many situations as possible, but
it's not always possible to provide an NMI, and there are cases where
CPUs may be unable to handle the NMI regardless.
This patch adds a test for panic() where all other CPUs are stuck with
interrupts disabled, which can be used to check whether the kernel
gracefully handles CPUs failing to respond to a stop, and whether NMIs
actually work to stop CPUs.
For example, on arm64 *without* an NMI, this results in:

Use a Python process pool to run the tests in parallel.
Not all tests can run in parallel, for instance tests that are not
namespaced and tests that use netdevsim, as they can conflict with one
another.
The code logic will split the tests into serial and parallel.
For the parallel tests, we build batches of 32 tests and queue each
batch on the process pool. For the serial tests, they are queued as a
whole into the process pool, which in turn executes them concurrently
with the parallel tests.
Even though the tests serialize on rtnl_lock in the kernel, this feature
showed results with a ~3x speedup on the wall time for the entire test suite
running in a VM:
Before - 4m32.502s
After - 1m19.202s
Examples:
In order to run tdc using 4 processes:
./tdc.py -J4 <...>
In order to run tdc using 1 process:
./tdc.py -J1 <...> || ./tdc.py <...>
Note that the kernel configuration will affect the speed of the tests,
especially if such configuration slows down process creation and/or
fork().

As of today, the current tdc architecture creates one netns and uses it
to run all tests. This assumption was embedded into the nsPlugin which
carried over as how the tests were written.
The tdc tests are by definition self contained and can,
theoretically, run in parallel. Even though in the kernel they will
serialize over the rtnl lock, we should expect a significant speedup of the
total wall time for the entire test suite, which is hitting close to
1100 tests at this point.
A first step to achieve this goal is to remove sharing of global resources like
veth/dummy interfaces and the netns. In this patch we 'localize' these
resources on a per test basis. Each test gets it's own netns, VETH/dummy interfaces.
The resources are spawned in the pre_suite phase, where tdc will prepare
all netns and interfaces for all tests. This is done in order to avoid
concurrency issues with netns / interfaces spawning and commands using
them. As tdc progresses, the resources are deleted after each test finishes
executing.
Tests that don't use the nsPlugin still run under the root namespace,
but are now required to manage any external resources like interfaces.
These cannot be parallelized as their definition doesn't allow it.
On the other hand, when using the nsPlugin, tests don't need to create
dummy/veth interfaces as these are handled already.

When building with Clang, I am getting many warnings from the selftests/rseq tree.
Here's one such example from rseq tree:
| param_test.c:1234:10: error: address argument to atomic operation must be a pointer to _Atomic type ('intptr_t *' (aka 'long *') invalid)
| 1234 | while (!atomic_load(&args->percpu_list_ptr)) {}

| 140 | #define atomic_load(object) __c11_atomic_load(object, __ATOMIC_SEQ_CST)
| | ^ ~~~~~~
Use compiler builtins `__atomic_load_n()` and `__atomic_store_n()` with
accompanying __ATOMIC_ACQUIRE and __ATOMIC_RELEASE, respectively. This
will fix the warnings because the compiler builtins do not expect their
arguments to have _Atomic type. This should also make TSAN happier.
