Hi, The memtostr*() and strtomem*() helpers are designed to move between C strings (NUL-terminated) and byte arrays (that may just be zero padded and may not be NUL-terminated). The "nonstring" attribute is used to annotated these kinds of byte arrays, and we can validate the annotation on the arguments of the helpers. Add the the infrastructure to do this, and then update all the places where these annotations are currently missing. -Kees Kees Cook (10): scsi: mptfusion: Mark device strings as nonstring scsi: mpi3mr: Mark device strings as nonstring scsi: mpt3sas: Mark device strings as nonstring scsi: qla2xxx: Mark device strings as nonstring string: kunit: Mark nonstring test strings as __nonstring x86/tdx: Mark message.str as nonstring uapi: stddef.h: Introduce __kernel_nonstring nilfs2: Mark on-disk strings as nonstring compiler.h: Introduce __must_be_noncstr() string.h: Validate memtostr*()/strtomem*() arguments more carefully arch/x86/coco/tdx/tdx.c | 2 +- drivers/message/fusion/mptsas.c | 8 ++++---- drivers/scsi/mpi3mr/mpi3mr_transport.c | 8 ++++---- drivers/scsi/mpt3sas/mpi/mpi2_cnfg.h | 2 +- drivers/scsi/mpt3sas/mpt3sas_transport.c | 8 ++++---- drivers/scsi/qla2xxx/qla_mr.h | 4 ++-- include/linux/compiler.h | 18 +++++++++++++++++- include/linux/string.h | 16 ++++++++++++---- include/uapi/linux/nilfs2_ondisk.h | 3 ++- include/uapi/linux/stddef.h | 6 ++++++ lib/string_kunit.c | 4 ++-- 11 files changed, 55 insertions(+), 24 deletions(-) -- 2.34.1
