2022-06-12platform/x86: hp-wmi: Resolve WMI query failures on some devicesJorge Lopez1-2/+4
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.

2022-06-05bluetooth: don't use bitmaps for random flag accessesLinus Torvalds5-39/+27
The bluetooth code uses our bitmap infrastructure for the two bits (!) of connection setup flags, and in the process causes odd problems when it converts between a bitmap and just the regular values of said bits. It's completely pointless to do things like bitmap_to_arr32() to convert a bitmap into a u32. It shoudln't have been a bitmap in the first place. The reason to use bitmaps is if you have arbitrary number of bits you want to manage (not two!), or if you rely on the atomicity guarantees of the bitmap setting and clearing. The code could use an "atomic_t" and use "atomic_or/andnot()" to set and clear the bit values, but considering that it then copies the bitmaps around with "bitmap_to_arr32()" and friends, there clearly cannot be a lot of atomicity requirements. So just use a regular integer. In the process, this avoids the warnings about erroneous use of bitmap_from_u64() which were triggered on 32-bit architectures when conversion from a u64 would access two words (and, surprise, surprise, only one word is needed - and indeed overkill - for a 2-bit bitmap). That was always problematic, but the compiler seems to notice it and warn about the invalid pattern only after commit 0a97953fd221 ("lib: add bitmap_{from,to}_arr64") changed the exact implementation details of 'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.

2022-06-05modpost: simplify mod->name allocationMasahiro Yamada1-13/+12
mod->name is set to the ELF filename with the suffix ".o" stripped. The current code calls strdup() and free() to manipulate the string, but a simpler approach is to pass new_module() with the name length subtracted by 2. Also, check if the passed filename ends with ".o" before stripping it. The current code blindly chops the suffix: tmp[strlen(tmp) - 2] = '\0' It will cause buffer under-run if strlen(tmp) < 2; Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Nick Desaulniers <ndesaulniers@google.com>
2022-06-05kbuild: factor out the common objtool argumentsMasahiro Yamada4-97/+52
scripts/Makefile.build and scripts/link-vmlinux.sh have similar setups for the objtool arguments. It was difficult to factor out them because all the vmlinux build rules were written in a shell script. It is somewhat tedious to touch the two files every time a new objtool option is supported. To reduce the code duplication, move the objtool for vmlinux.o into scripts/Makefile.vmlinux_o. Then, move the common macros to Makefile.lib so they are shared between Makefile.build and Makefile.vmlinux_o.

2022-06-03firmware_loader: enable XZ by default if compressed support is enabledLinus Torvalds1-0/+1
Commit 23cfbc6ec44e ("firmware: Add the support for ZSTD-compressed firmware files") added support for ZSTD compression, but in the process also made the previously default XZ compression a config option. That means that anybody who upgrades their kernel and does a make oldconfig to update their configuration, will end up without the XZ compression that the configuration used to have. Add the 'default y' to make sure this doesn't happen. The whole compression question should probably be improved upon, since it is now possible to "enable" compression in the kernel config but not enable any actual compression algorithm, which makes it all very useless. It makes no sense to ask Kconfig questions that enable situations that are nonsensical like that. This at least fixes the immediate problem of a kernel update resulting in a nonbootable machine because of a missed option.
