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/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 6015b1aca1a233379625385feb01dd014aca60b5 # < make -s -j 32 ARCH=sh O=/kisskb/build/linus_sh-allyesconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sh4-linux/bin/sh4-linux- allyesconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # < make -s -j 32 ARCH=sh O=/kisskb/build/linus_sh-allyesconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sh4-linux/bin/sh4-linux- help # make -s -j 32 ARCH=sh O=/kisskb/build/linus_sh-allyesconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sh4-linux/bin/sh4-linux- olddefconfig # make -s -j 32 ARCH=sh O=/kisskb/build/linus_sh-allyesconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h <stdin>:1517:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S: Assembler messages: /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:85: Warning: overflow in branch to __restore_all; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:357: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:360: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence {standard input}: Assembler messages: {standard input}: Warning: end of file not at end of a line; newline inserted {standard input}:1118: Error: unknown pseudo-op: `.' sh4-linux-gcc: internal compiler error: Segmentation fault signal terminated program cc1 Please submit a full bug report, with preprocessed source if appropriate.
