It is indeed the allocation size of a # cpumask. # # But the code also assumes that the whole allocation is initialized # without actually doing so itself. That's wrong, because we might have # fixed-size allocations (making copying and clearing more efficient), but # not all of it is then necessarily used if 'nr_cpu_ids' is smaller. # # Having checked other users of 'cpumask_size()', they all seem to be ok, # either using it purely for the allocation size, or explicitly zeroing # the cpumask before using the size in bytes to copy it. # # See for example the ublk_ctrl_get_queue_affinity() function that uses # the proper 'zalloc_cpumask_var()' to make sure that the whole mask is # cleared, whether the storage is on the stack or if it was an external # allocation. # # Fix this by just zeroing the allocation before using it. Do the same # for the compat version of sched_getaffinity(), which had the same logic. # # Also, for consistency, make sched_getaffinity() use 'cpumask_bits()' to # access the bits. For a cpumask_var_t, it ends up being a pointer to the # same data either way, but it's just a good idea to treat it like you # would a 'cpumask_t'. The compat case already did that. # # Reported-by: Ryan Roberts <ryan.roberts@arm.com> # Link: https://lore.kernel.org/lkml/7d026744-6bd6-6827-0471-b5e8eae0be3f@arm.com/ # Cc: Yury Norov <yury.norov@gmail.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-11.3.0-nolibc/m68k-linux/bin/m68k-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.3.0-nolibc/m68k-linux/bin/m68k-linux-ld --version # < git log --format=%s --max-count=1 6015b1aca1a233379625385feb01dd014aca60b5 # < make -s -j 24 ARCH=m68k O=/kisskb/build/linus_m68k-allmodconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/m68k-linux/bin/m68k-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # < make -s -j 24 ARCH=m68k O=/kisskb/build/linus_m68k-allmodconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/m68k-linux/bin/m68k-linux- help # make -s -j 24 ARCH=m68k O=/kisskb/build/linus_m68k-allmodconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/m68k-linux/bin/m68k-linux- olddefconfig # make -s -j 24 ARCH=m68k O=/kisskb/build/linus_m68k-allmodconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/m68k-linux/bin/m68k-linux- /kisskb/src/drivers/media/i2c/imx290.c:1090:12: error: 'imx290_runtime_suspend' defined but not used [-Werror=unused-function] 1090 \| static int imx290_runtime_suspend(struct device dev) \| ^~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/media/i2c/imx290.c:1082:12: error: 'imx290_runtime_resume' defined but not used [-Werror=unused-function] 1082 \| static int imx290_runtime_resume(struct device dev) \| ^~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors make[5]: * [/kisskb/src/scripts/Makefile.build:252: drivers/media/i2c/imx290.o] Error 1 make[5]: * Waiting for unfinished jobs.... make[4]: * [/kisskb/src/scripts/Makefile.build:494: drivers/media/i2c] Error 2 make[3]: * [/kisskb/src/scripts/Makefile.build:494: drivers/media] Error 2 make[3]: * Waiting for unfinished jobs.... make[2]: * [/kisskb/src/scripts/Makefile.build:494: drivers] Error 2 make[1]: * [/kisskb/src/Makefile:2028: .] Error 2 make: * [Makefile:226: __sub-make] Error 2 Command 'make -s -j 24 ARCH=m68k O=/kisskb/build/linus_m68k-allmodconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/m68k-linux/bin/m68k-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_m68k-allmodconfig_m68k-gcc11 # Build took: 0:16:44.554969
