Also # some fixes to SCSI string handling were carried in my tree since the # helper for those was introduce here. Beyond that, just little fixes # all around: objtool getting confused about LKDTM+KCFI, preparing for # future refactors (constification of sysctl tables, additional # __counted_by annotations), a Clang UBSAN+i386 crash fix, and adding # more options in the hardening.config Kconfig fragment. # # Summary: # # - selftests: Add str*cmp tests (Ivan Orlov) # # - __counted_by: provide UAPI for _le/_be variants (Erick Archer) # # - Various strncpy deprecation refactors (Justin Stitt) # # - stackleak: Use a copy of soon-to-be-const sysctl table (Thomas # Weißschuh) # # - UBSAN: Work around i386 -regparm=3 bug with Clang prior to # version 19 # # - Provide helper to deal with non-NUL-terminated string copying # # - SCSI: Fix older string copying bugs (with new helper) # # - selftests: Consolidate string helper behavioral tests # # - selftests: add memcpy() fortify tests # # - string: Add additional __realloc_size() annotations for "dup" # helpers # # - LKDTM: Fix KCFI+rodata+objtool confusion # # -
