2022-06-27docs/doc-guide: Add footnote on Inkscape for better images in PDF documentsAkira Yokosawa
With kernel releases v5.18 and later, if you have Inkscape, images embedded in PDF documents are of vector graphics, not the raster images as are the case with pre-v5.18 releases. Even with pre-5.18 releases, having Inkscape would improve images converted from some of SVG files which are not fully covered by the limited capability of rsvg-convert(1) [1]. Add a footnote mentioning the expected improvements of such images.

2022-06-13scripts: kernel-doc: Always increment warnings counterNiklas Söderlund
Some warnings do not increment the warnings counter making the behavior of running kernel-doc with -Werror unlogical as some warnings will be generated but not treated as errors. Fix this by creating a helper function that always incrementing the warnings counter every time a warning is emitted. There is one location in get_sphinx_version() where a warning is not touched as it concerns the execution environment of the kernel-doc and not the documentation being processed. Incrementing the counter only have effect when running kernel-doc in either verbose mode (-v or environment variable KBUILD_VERBOSE) or when treating warnings as errors (-Werror or environment variable KDOC_WERROR). In both cases the number of warnings printed is printed to stderr and for the later the exit code of kernel-doc is non-zero if warnings where encountered. Simple test case to demo one of the warnings, $ cat test.c /** * foo() - Description */ int bar(); # Without this change $ ./scripts/kernel-doc -Werror -none test.c test.c:4: warning: expecting prototype for foo(). Prototype was for bar() instead # With this change $ ./scripts/kernel-doc -Werror -none test.c test.c:4: warning: expecting prototype for foo(). Prototype was for bar() instead 1 warnings as Errors Signed-off-by: Niklas Söderlund <niklas.soderlund@corigine.com> Link: https://lore.kernel.org/r/20220613090510.3088294-1-niklas.soderlund@corigine.com Signed-off-by: Jonathan Corbet <corbet@lwn.net>

git://git.kernel.org/pub/scm/linux/kernel/git/crng/random Pull random number generator fixes from Jason Donenfeld: - A fix for a 5.19 regression for a case in which early device tree initializes the RNG, which flips a static branch. On most plaforms, jump labels aren't initialized until much later, so this caused splats. On a few mailing list threads, we cooked up easy fixes for arm64, arm32, and risc-v. But then things looked slightly more involved for xtensa, powerpc, arc, and mips. And at that point, when we're patching 7 architectures in a place before the console is even available, it seems like the cost/risk just wasn't worth it. So random.c works around it now by checking the already exported `static_key_initialized` boolean, as though somebody already ran into this issue in the past. I'm not super jazzed about that; it'd be prettier to not have to complicate downstream code. But I suppose it's practical. - A few small code nits and adding a missing __init annotation. - A change to the default config values to use the cpu and bootloader's seeds for initializing the RNG earlier. This brings them into line with what all the distros do (Fedora/RHEL, Debian, Ubuntu, Gentoo, Arch, NixOS, Alpine, SUSE, and Void... at least), and moreover will now give us test coverage in various test beds that might have caught the above device tree bug earlier. - A change to WireGuard CI's configuration to increase test coverage around the RNG. - A documentation comment fix to unrelated maintainerless CRC code that I was asked to take, I guess because it has to do with polynomials (which the RNG thankfully no longer uses). * tag 'random-5.19-rc2-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: wireguard: selftests: use maximum cpu features and allow rng seeding random: remove rng_has_arch_random() random: credit cpu and bootloader seeds by default random: do not use jump labels before they are initialized random: account for arch randomness in bits random: mark bootloader randomness code as __init random: avoid checking crng_ready() twice in random_init() crc-itu-t: fix typo in CRC ITU-T polynomial comment

2022-06-12platform/x86: hp-wmi: Resolve WMI query failures on some devicesJorge Lopez
WMI queries fail on some devices where the ACPI method HWMC unconditionally attempts to create Fields beyond the buffer if the buffer is too small, this breaks essential features such as power profiles: CreateByteField (Arg1, 0x10, D008) CreateByteField (Arg1, 0x11, D009) CreateByteField (Arg1, 0x12, D010) CreateDWordField (Arg1, 0x10, D032) CreateField (Arg1, 0x80, 0x0400, D128) In cases where args->data had zero length, ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D008] at bit offset/length 128/8 exceeds size of target Buffer (128 bits) (20211217/dsopcode-198) was obtained. ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D009] at bit offset/length 136/8 exceeds size of target Buffer (136bits) (20211217/dsopcode-198) The original code created a buffer size of 128 bytes regardless if the WMI call required a smaller buffer or not. This particular behavior occurs in older BIOS and reproduced in OMEN laptops. Newer BIOS handles buffer sizes properly and meets the latest specification requirements. This is the reason why testing with a dynamically allocated buffer did not uncover any failures with the test systems at hand. This patch was tested on several OMEN, Elite, and Zbooks. It was confirmed the patch resolves HPWMI_FAN GET/SET calls in an OMEN Laptop 15-ek0xxx. No problems were reported when testing on several Elite and Zbooks notebooks.

2022-06-11iov_iter: fix build issue due to possible type mis-matchLinus Torvalds
Commit 6c77676645ad ("iov_iter: Fix iter_xarray_get_pages{,_alloc}()") introduced a problem on some 32-bit architectures (at least arm, xtensa, csky,sparc and mips), that have a 'size_t' that is 'unsigned int'. The reason is that we now do min(nr * PAGE_SIZE - offset, maxsize); where 'nr' and 'offset' and both 'unsigned int', and PAGE_SIZE is 'unsigned long'. As a result, the normal C type rules means that the first argument to 'min()' ends up being 'unsigned long'. In contrast, 'maxsize' is of type 'size_t'. Now, 'size_t' and 'unsigned long' are always the same physical type in the kernel, so you'd think this doesn't matter, and from an actual arithmetic standpoint it doesn't. But on 32-bit architectures 'size_t' is commonly 'unsigned int', even if it could also be 'unsigned long'. In that situation, both are unsigned 32-bit types, but they are not the *same* type. And as a result 'min()' will complain about the distinct types (ignore the "pointer types" part of the error message: that's an artifact of the way we have made 'min()' check types for being the same): lib/iov_iter.c: In function 'iter_xarray_get_pages': include/linux/minmax.h:20:35: error: comparison of distinct pointer types lacks a cast [-Werror] 20 | (!!(sizeof((typeof(x) *)1 == (typeof(y) *)1))) | ^~ lib/iov_iter.c:1464:16: note: in expansion of macro 'min' 1464 | return min(nr * PAGE_SIZE - offset, maxsize); | ^~~ This was not visible on 64-bit architectures (where we always define 'size_t' to be 'unsigned long'). Force these cases to use 'min_t(size_t, x, y)' to make the type explicit and avoid the issue. [ Nit-picky note: technically 'size_t' doesn't have to match 'unsigned long' arithmetically. We've certainly historically seen environments with 16-bit address spaces and 32-bit 'unsigned long'. Similarly, even in 64-bit modern environments, 'size_t' could be its own type distinct from 'unsigned long', even if it were arithmetically identical. So the above type commentary is only really descriptive of the kernel environment, not some kind of universal truth for the kinds of wild and crazy situations that are allowed by the C standard ] Reported-by: Sudip Mukherjee <sudipm.mukherjee@gmail.com> Link: https://lore.kernel.org/all/YqRyL2sIqQNDfky2@debian/ Cc: Jeff Layton <jlayton@kernel.org> Cc: David Howells <dhowells@redhat.com> Cc: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2022-06-11wireguard: selftests: use maximum cpu features and allow rng seedingJason A. Donenfeld
By forcing the maximum CPU that QEMU has available, we expose additional capabilities, such as the RNDR instruction, which increases test coverage. This then allows the CI to skip the fake seeding step in some cases. Also enable STRICT_KERNEL_RWX to catch issues related to early jump labels when the RNG is initialized at boot.
