Pull overflow updates from Kees Cook:
"These changes come in roughly two halves: support of Gustavo A. R.
Silva's struct_size() work via additional helpers for catching
overflow allocation size calculations, and conversions of selftests to
KUnit (which includes some tweaks for UML + Clang):
- Convert overflow selftest to KUnit
- Convert stackinit selftest to KUnit
- Implement size_t saturating arithmetic helpers
- Allow struct_size() to be used in initializers"
* tag 'overflow-v5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux:
lib: stackinit: Convert to KUnit
um: Allow builds with Clang
lib: overflow: Convert to Kunit

Add SUBARCH target for Clang+um (which must go last, not alphabetically,
so the other SUBARCHes are assigned). Remove open-coded "DEFINE"
macro, instead using linux/kbuild.h's version which was updated to use
Clang-friendly assembly in commit cf0c3e68aa81 ("kbuild: fix asm-offset
generation to work with clang"). Redefine "DEFINE_LONGS" in terms of
"COMMENT" and "DEFINE" so that the intended coment actually has useful
content. Add a missed "break" to avoid implicit fall-through warnings.
This lets me run KUnit tests with Clang:
$ ./tools/testing/kunit/kunit.py run --make_options LLVM=1

Currently, when there is no FILE argument following a switch such
as -man, -rst, or -none, kernel-doc exits with a warning from perl
(long msg folded):
Use of uninitialized value $ARGV[0] in pattern match (m//)
at ./scripts/kernel-doc line 438.
, which is unhelpful.
Improve the behavior by adding a check at the bottom of parsing
loop.
If the argument is absent, display help text and exit with
the code of 1 (via usage()).

What for? To improve the script maintainability.
1. License
As stated by Jonathan Corbet in the reply to my version 1, the SPDX line
is enough.
2. The to-do list comment
As suggested by Jonathan Corbet in reply to my version 3, this section
doesn't need to be transitioned. And so it is removed for clarity.
3. The historical changelog comments
As suggested by Jonathan Corbet in a reply to v3, this section can go.
I wanted to keep it, but since it doesn't contain copyright notices,
let's just have it clean and simple.
4. The "format of comments" comment block
As suggested by Jani Nikula in a reply to my first version of this
transformation, Documentation/doc-guide/kernel-doc.rst can serve as the
information hub for comment formatting. The section DESCRIPTION already
points there, so the original comment block can just be removed.

The NAME section provides the doc title, while SYNOPSIS contains
the basic syntax and usage description, which will be printed
in the help document and in the error output produced on wrong script
usage.
The rationale is to give users simple and succinct enlightment,
at the same time structuring the script internally for the maintainers.
In the synopsis, Rst-only options are grouped around rst, and the rest is
arranged as in the OPTIONS subsections (yet to be translated into POD,
check at the end of the series).
The third of the basic sections, DESCRIPTION, is added separately.

-Wunaligned-access is a new warning in clang that is default enabled for
arm and arm64 under certain circumstances within the clang frontend (see
LLVM commit below). On v5.17-rc2, an ARCH=arm allmodconfig build shows
1284 total/70 unique instances of this warning (most of the instances
are in header files), which is quite noisy.
To keep a normal build green through CONFIG_WERROR, only show this
warning with W=1, which will allow automated build systems to catch new
instances of the warning so that the total number can be driven down to
zero eventually since catching unaligned accesses at compile time would
be generally useful.

The 'shell' built-in only returns the first 256 bytes of the command's
output. In some cases, 'shell' is used to return a path; by bumping up
the buffer size to 4096 this lets us capture up to PATH_MAX.
The specific case where I ran into this was due to commit 1e860048c53e
("gcc-plugins: simplify GCC plugin-dev capability test"). After this
change, we now use `$(shell,$(CC) -print-file-name=plugin)` to return
a path; if the gcc path is particularly long, then the path ends up
truncated at the 256 byte mark, which makes the HAVE_GCC_PLUGINS
depends test always fail.

First S390 complained that the sorting of the mcount sections at build
time caused the kernel to crash on their architecture. Now PowerPC is
complaining about it too. And also ARM64 appears to be having issues.
It may be necessary to also update the relocation table for the values
in the mcount table. Not only do we have to sort the table, but also
update the relocations that may be applied to the items in the table.
If the system is not relocatable, then it is fine to sort, but if it is,
some architectures may have issues (although x86 does not as it shifts all
addresses the same).
Add a HAVE_BUILDTIME_MCOUNT_SORT that an architecture can set to say it is
safe to do the sorting at build time.
Also update the config to compile in build time sorting in the sorttable
code in scripts/ to depend on CONFIG_BUILDTIME_MCOUNT_SORT.

The object-size sanitizer is redundant to -Warray-bounds, and
inappropriately performs its checks at run-time when all information
needed for the evaluation is available at compile-time, making it quite
difficult to use:
https://bugzilla.kernel.org/show_bug.cgi?id=214861
With -Warray-bounds almost enabled globally, it doesn't make sense to
keep this around.

One exceptions to the COMMIT_LOG_LONG_LINE rule is a file path followed
by ':'. That is typically some sort diagnostic message from a compiler
or a build tool, in which case we don't want to wrap the lines but keep
the message unmodified.
The regular expression used to match this pattern currently doesn't
accept absolute paths or + characters. This can result in false

dtx_diff suggests to use <(...) syntax to pipe two inputs into it, but
this has never worked: The /proc/self/fds/... paths passed by the shell
will fail the `[ -f "${dtx}" ] && [ -r "${dtx}" ]` check in compile_to_dts,
but even with this check removed, the function cannot work: hexdump will
eat up the DTB magic, making the subsequent dtc call fail, as a pipe
cannot be rewound.
Simply remove this broken example, as there is already an alternative one
that works fine.

When the kernel starts, the initialization of ftrace takes
up a portion of the time (approximately 6~8ms) to sort mcount
addresses. We can save this time by moving mcount-sorting to
compile time.

Some architectures support self-extracting kernel, which embeds the
compressed vmlinux.
It has 4 byte data at the end so the decompressor can know the vmlinux
size beforehand.
GZIP natively has it in the trailer, but for the other compression
algorithms, the hand-crafted trailer is added.
It is unneeded to generate such _corrupted_ compressed files because
it is possible to pass the size data as a separate file.
For example, the assembly code:
.incbin "compressed-vmlinux-with-size-data"
can be transformed to:
.incbin "compressed-vmlinux"
.incbin "size-data"
My hope is, after some reworks of the decompressors, the macros
cmd_{bzip2,lzma,lzo,lz4,xzkern,zstd22}_with_size will go away.
This new macro, cmd_file_size, will be useful to generate a separate
size-data file.

GZIP-compressed files end with 4 byte data that represents the size
of the original input. The decompressors (the self-extracting kernel)
exploit it to know the vmlinux size beforehand. To mimic the GZIP's
trailer, Kbuild provides cmd_{bzip2,lzma,lzo,lz4,xzkern,zstd22}.
Unfortunately these macros are used everywhere despite the appended
size data is only useful for the decompressors.
There is no guarantee that such hand-crafted trailers are safely ignored.
In fact, the kernel refuses compressed initramdfs with the garbage data.
That is why usr/Makefile overrides size_append to make it no-op.
To limit the use of such broken compressed files, this commit renames
the existing macros as follows:
cmd_bzip2 --> cmd_bzip2_with_size
cmd_lzma --> cmd_lzma_with_size
cmd_lzo --> cmd_lzo_with_size
cmd_lz4 --> cmd_lz4_with_size
cmd_xzkern --> cmd_xzkern_with_size
cmd_zstd22 --> cmd_zstd22_with_size
To keep the decompressors working, I updated the following Makefiles
accordingly:
arch/arm/boot/compressed/Makefile
arch/h8300/boot/compressed/Makefile
arch/mips/boot/compressed/Makefile
arch/parisc/boot/compressed/Makefile
arch/s390/boot/compressed/Makefile
arch/sh/boot/compressed/Makefile
arch/x86/boot/compressed/Makefile
I reused the current macro names for the normal usecases; they produce
the compressed data in the proper format.
I did not touch the following:
arch/arc/boot/Makefile
arch/arm64/boot/Makefile
arch/csky/boot/Makefile
arch/mips/boot/Makefile
arch/riscv/boot/Makefile
arch/sh/boot/Makefile
kernel/Makefile
This means those Makefiles will stop appending the size data.
I dropped the 'override size_append' hack from usr/Makefile.

The appended file size is only used by the decompressors, which some
architectures support.
As the comment "zstd22 is used for kernel compression" says, cmd_zstd22
is used in arch/{mips,s390,x86}/boot/compressed/Makefile.
On the other hand, there is no good reason to append the file size to
cmd_zstd since it is used for other purposes.
Actually cmd_zstd is only used in usr/Makefile, where the appended file
size is rather harmful.
The initramfs with its file size appended is considered as corrupted
data, so commit 65e00e04e5ae ("initramfs: refactor the initramfs build
rules") added 'override size_append := :' to make it no-op.
As a conclusion, this $(size_append) should not exist here.
