Merge tag 'hardening-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull hardening updates from Kees Cook: "The bulk of the changes here are related to refactoring and expanding the KUnit tests for string helper and fortify behavior. Some trivial strncpy replacements in fs/ were carried in my tree. 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 - hardening.config: Enable KCFI" * tag 'hardening-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: (29 commits) uapi: stddef.h: Provide UAPI macros for __counted_by_{le, be} stackleak: Use a copy of the ctl_table argument string: Add additional __realloc_size() annotations for "dup" helpers kunit/fortify: Fix replaced failure path to unbreak __alloc_size hardening: Enable KCFI and some other options lkdtm: Disable CFI checking for perms functions kunit/fortify: Add memcpy() tests kunit/fortify: Do not spam logs with fortify WARNs kunit/fortify: Rename tests to use recommended conventions init: replace deprecated strncpy with strscpy_pad kunit/fortify: Fix mismatched kvalloc()/vfree() usage scsi: qla2xxx: Avoid possible run-time warning with long model_num scsi: mpi3mr: Avoid possible run-time warning with long manufacturer strings scsi: mptfusion: Avoid possible run-time warning with long manufacturer strings fs: ecryptfs: replace deprecated strncpy with strscpy hfsplus: refactor copy_name to not use strncpy reiserfs: replace deprecated strncpy with scnprintf virt: acrn: replace deprecated strncpy with strscpy ubsan: Avoid i386 UBSAN handler crashes with Clang ubsan: Remove 1-element array usage in debug reporting ...
