git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull hardening updates from Kees Cook: "There are three areas of note: A bunch of strlcpy()->strscpy() conversions ended up living in my tree since they were either Acked by maintainers for me to carry, or got ignored for multiple weeks (and were trivial changes). The compiler option '-fstrict-flex-arrays=3' has been enabled globally, and has been in -next for the entire devel cycle. This changes compiler diagnostics (though mainly just -Warray-bounds which is disabled) and potential UBSAN_BOUNDS and FORTIFY _warning_ coverage. In other words, there are no new restrictions, just potentially new warnings. Any new FORTIFY warnings we've seen have been fixed (usually in their respective subsystem trees). For more details, see commit df8fc4e934c12b. The under-development compiler attribute __counted_by has been added so that we can start annotating flexible array members with their associated structure member that tracks the count of flexible array elements at run-time. It is possible (likely?) that the exact syntax of the attribute will change before it is finalized, but GCC and Clang are working together to sort it out. Any changes can be made to the macro while we continue to add annotations. As an example of that last case, I have a treewide commit waiting with such annotations found via Coccinelle: https://git.kernel.org/linus/adc5b3cb48a049563dc673f348eab7b6beba8a9b Also see commit dd06e72e68bcb4 for more details.

2023-06-15ACPI: sleep: Avoid breaking S3 wakeup due to might_sleep()Rafael J. Wysocki
The addition of might_sleep() to down_timeout() caused the latter to enable interrupts unconditionally in some cases, which in turn broke the ACPI S3 wakeup path in acpi_suspend_enter(), where down_timeout() is called by acpi_disable_all_gpes() via acpi_ut_acquire_mutex(). Namely, if CONFIG_DEBUG_ATOMIC_SLEEP is set, might_sleep() causes might_resched() to be used and if CONFIG_PREEMPT_VOLUNTARY is set, this triggers __cond_resched() which may call preempt_schedule_common(), so __schedule() gets invoked and it ends up with enabled interrupts (in the prev == next case). Now, enabling interrupts early in the S3 wakeup path causes the kernel to crash. Address this by modifying acpi_suspend_enter() to disable GPEs without attempting to acquire the sleeping lock which is not needed in that code path anyway.

2023-06-05ACPI: scan: Reduce overhead related to devices with dependenciesRafael J. Wysocki
Notice that all of the objects for which the acpi_scan_check_dep() return value is greater than 0 are present in acpi_dep_list as consumers (there may be multiple entries for one object, but that is not a problem), so after carrying out the initial ACPI namespace walk in which devices with dependencies are skipped, acpi_bus_scan() can simply walk acpi_dep_list and enumerate all of the unique consumer objects from there and their descendants instead of walking the entire target branch of the ACPI namespace and looking for device objects that have not been enumerated yet in it. Because walking acpi_dep_list is generally less overhead than walking the entire ACPI namespace, use the observation above to reduce the system initialization overhead related to ACPI, which is particularly important on large systems.

Since commit 5aa9d943e9b6 ("ACPI: video: Don't enable fallback path for creating ACPI backlight by default"), the delayed registering of acpi_video# backlight devices has been disabled by default. The few bugreports where this option was used as a workaround were all cases where the GPU driver did not call acpi_video_register_backlight() and the workaround was to pass video.register_backlight_delay=1. With the recent "ACPI: video: Make acpi_backlight=video work independent from GPU driver" changes acpi_backlight=video can be used to achieve the same result. So there is no need for the register_backlight_delay option + code anymore.

ACPICA commit bfdd3446e7caf795c85c70326c137023942972c5 Similar to "Replace one-element array with flexible-array", replace the 1-element array with a proper flexible array member as defined by C99. This allows the code to operate without tripping compile-time and run- time bounds checkers (e.g. via __builtin_object_size(), -fsanitize=bounds, and/or -fstrict-flex-arrays=3). Note that the spec requires there be at least one interrupt, so use a union to keep space allocated for this. The only binary change in .text and .data sections is some rearrangement by the compiler of acpi_dm_address_common(), but appears to be harmless.

ACPICA commit f4a3afd78c28dede0907f47951f0b73c9a776d4e The "Source" array is actually a dynamically sized array, but it is defined as a fixed-size 4 byte array. This results in tripping both compile-time and run-time bounds checkers (e.g. via either __builtin_object_size() or -fsanitize=bounds). To retain the padding, create a union with an unused Pad variable of size 4, and redefine Source as a proper flexible array member. No binary changes appear in the .text nor .data sections.

2023-04-06ACPICA: Introduce ACPI_FLEX_ARRAYKees Cook
ACPICA commit e73b227e8e475c20cc394f237ea35d592fdf9ec3 In order to enable using -fstrict-flex-arrays with GCC and Clang in the Linux kernel, each trailing dynamically sized array must be defined as proper C99 "flexible array members" (FAM). Unfortunately, ACPICA has a bunch of technical debt, dating back to before even the GNU extension of 0-length arrays, meaning the code base has many 1-element and 0-length arrays defined at the end of structures that should actually be FAMs. One limitation of the C99 FAM specification is the accidental requirement that they cannot be in unions or alone in structs. There is no real-world reason for this, though, and, actually, the existing GNU extension permits this for 0-length arrays (which get treated as FAMs). Add the ACPI_FLEX_ARRAY() helper macro to work around this requirement so that FAMs can be defined in unions or alone in structs. Since this behavior still depends on GNU extensions, keep the macro specific to GCC (and Clang) builds. In this way, MSVC will continue to use 0-length arrays (since it does not support the union work-around). When MSVC grows support for this in the future, the macro can be updated.

This allows the code to operate without tripping compile-time and run- time bounds checkers (e.g. via __builtin_object_size(), -fsanitize=bounds, and/or -fstrict-flex-arrays=3). Unlike struct acpi_nfit_flush_address and struct acpi_nfit_smbios, which had their sizeof() uses adjusted in code, struct acpi_nfit_interleave did not. This appears to have been a bug. After this change, there is a binary difference in acpi_dm_dump_nfit() since the size of the structure now has the correct size, as the prior result was including the trailing U32: - mov $0x14,%ebp + mov $0x10,%ebp Link: https://github.com/acpica/acpica/commit/e66decc6 Signed-off-by: Bob Moore <robert.moore@intel.com> Reviewed-by: Dan Williams <dan.j.williams@intel.com> Tested-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Rafael J.

ACPICA commit f0c4a06f1dfc4886d4e0c2aa30bc57b10c5a8c53 Like many tables, this is a header followed by multiple subtables of varying self-identifying types, and ACPICA does not normally add a field for the subtables, instead relying on pointer arithmetic past the end of the first header struct, since indexing a flexible array member is meaningless for variable-length entries. If we really wanted a field for this, we could use a u8 flexible array member, but it contradicts the current style. Using void *, however, is categorically wrong, as ACPI tables never contain native C-language pointers.

x86 ACPI boards which ship with only Android as their factory image usually have pretty broken ACPI tables, relying on everything being hardcoded in the factory kernel image and often disabling parts of the ACPI enumeration kernel code to avoid the broken tables causing issues. Part of this broken ACPI code is that sometimes these boards have _AEI ACPI GPIO event handlers which are broken. So far this has been dealt with in the platform/x86/x86-android-tablets.c module, which contains various workarounds for these devices, by it calling acpi_gpiochip_free_interrupts() on gpiochip-s with troublesome handlers to disable the handlers. But in some cases this is too late, if the handlers are of the edge type then gpiolib-acpi.c's code will already have run them at boot. This can cause issues such as GPIOs ending up as owned by "ACPI:OpRegion", making them unavailable for drivers which actually need them. Boards with these broken ACPI tables are already listed in drivers/acpi/x86/utils.c for e.g. acpi_quirk_skip_i2c_client_enumeration(). Extend the quirks mechanism for a new acpi_quirk_skip_gpio_event_handlers() helper, this re-uses the DMI-ids rather then having to duplicate the same DMI table in gpiolib-acpi.c . Also add the new ACPI_QUIRK_SKIP_GPIO_EVENT_HANDLERS quirk to existing boards with troublesome ACPI gpio event handlers, so that the current acpi_gpiochip_free_interrupts() hack can be removed from x86-android-tablets.c .

2023-03-05Remove Intel compiler supportMasahiro Yamada
include/linux/compiler-intel.h had no update in the past 3 years. We often forget about the third C compiler to build the kernel. For example, commit a0a12c3ed057 ("asm goto: eradicate CC_HAS_ASM_GOTO") only mentioned GCC and Clang. init/Kconfig defines CC_IS_GCC and CC_IS_CLANG but not CC_IS_ICC, and nobody has reported any issue. I guess the Intel Compiler support is broken, and nobody is caring about it. Harald Arnesen pointed out ICC (classic Intel C/C++ compiler) is deprecated: $ icc -v icc: remark #10441: The Intel(R) C++ Compiler Classic (ICC) is deprecated and will be removed from product release in the second half of 2023. The Intel(R) oneAPI DPC++/C++ Compiler (ICX) is the recommended compiler moving forward. Please transition to use this compiler. Use '-diag-disable=10441' to disable this message. icc version 2021.7.0 (gcc version 12.1.0 compatibility) Arnd Bergmann provided a link to the article, "Intel C/C++ compilers complete adoption of LLVM". lib/zstd/common/compiler.h and lib/zstd/compress/zstd_fast.c were kept untouched for better sync with https://github.com/facebook/zstd Link: https://www.intel.com/content/www/us/en/developer/articles/technical/adoption-of-llvm-complete-icx.html Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Acked-by: Arnd Bergmann <arnd@arndb.de> Reviewed-by: Nick Desaulniers <ndesaulniers@google.com> Reviewed-by: Nathan Chancellor <nathan@kernel.org> Reviewed-by: Miguel Ojeda <ojeda@kernel.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
