Yes, the arguments to # drm_buddy_init() and drm_buddy_alloc_blocks() are in fact of type 'u64', # but none of the values here are remotely relevant, and the compiler will # happily just do the type expansion. # # Of course, in a perfect world the compiler would also have just noticed # that all the values in question are tiny, and range analysis would have # shown that doing a 64-bit divide is pointless, but that is admittedly # expecting a fair amount of the compiler. # # IOW, we shouldn't write code that the compiler then has to notice is # unnecessarily complicated just to avoid extra work. We do have fairly # high expectations of compilers, but kernel code should be reasonable to # begin with. # # It turns out that there are also other issues with this code: the KUnit # assertion messages have incorrect types in the format strings, but # that's a widely spread issue caused by the KUnit infrastructure not # having enabled format string verification. We'll get that sorted out # separately. # # Reported-by: Guenter Roeck <linux@roeck-us.net> # Fixes: a64056bb5a32 ("drm/tests/drm_buddy: add alloc_contiguous test") # Link: https://lore.kernel.org/all/538327ff-8d34-41d5-a9ae-1a334744f5ae@roeck-us.net/ # Cc: Matthew Auld <matthew.auld@intel.com> # Cc: Arunpravin Paneer Selvam <Arunpravin.PaneerSelvam@amd.com> # Cc: Christian König <christian.koenig@amd.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 fca7526b7d8910c6125cb1ebc3e78ccd5f50ec52 # make -s -j 40 ARCH=mips O=/kisskb/build/linus_allmodconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MIPS_CPS_NS16550_BASE=0x1b0003f8 # Added to kconfig CONFIG_MIPS_CPS_NS16550_SHIFT=0 # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig # < make -s -j 40 ARCH=mips O=/kisskb/build/linus_allmodconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux- help # make -s -j 40 ARCH=mips O=/kisskb/build/linus_allmodconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux- olddefconfig .config:14883:warning: override: reassigning to symbol MIPS_CPS_NS16550_SHIFT # make -s -j 40 ARCH=mips O=/kisskb/build/linus_allmodconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux- In file included from /kisskb/src/include/linux/string.h:292, from /kisskb/src/include/linux/bitmap.h:12, from /kisskb/src/include/linux/cpumask.h:12, from /kisskb/src/include/linux/smp.h:13, from /kisskb/src/arch/mips/include/asm/cpu-type.h:12, from /kisskb/src/arch/mips/include/asm/timex.h:19, from /kisskb/src/include/linux/timex.h:67, from /kisskb/src/include/linux/time32.h:13, from /kisskb/src/include/linux/time.h:60, from /kisskb/src/include/linux/jiffies.h:10, from /kisskb/src/include/linux/ktime.h:25, from /kisskb/src/include/linux/iopoll.h:11, from /kisskb/src/drivers/crypto/intel/qat/qat_common/adf_gen4_hw_data.c:3: In function 'fortify_memcpy_chk', inlined from 'adf_gen4_init_thd2arb_map' at /kisskb/src/drivers/crypto/intel/qat/qat_common/adf_gen4_hw_data.c:401:3: /kisskb/src/include/linux/fortify-string.h:528:4: error: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()?
