Merge tag 'hardening-v6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull hardening updates from Kees Cook: "As has become normal, changes are scattered around the tree (either explicitly maintainer Acked or for trivial stuff that went ignored): - Carve out the new CONFIG_LIST_HARDENED as a more focused subset of CONFIG_DEBUG_LIST (Marco Elver) - Fix kallsyms lookup failure under Clang LTO (Yonghong Song) - Clarify documentation for CONFIG_UBSAN_TRAP (Jann Horn) - Flexible array member conversion not carried in other tree (Gustavo A. R. Silva) - Various strlcpy() and strncpy() removals not carried in other trees (Azeem Shaikh, Justin Stitt) - Convert nsproxy.count to refcount_t (Elena Reshetova) - Add handful of __counted_by annotations not carried in other trees, as well as an LKDTM test - Fix build failure with gcc-plugins on GCC 14+ - Fix selftests to respect SKIP for signal-delivery tests - Fix CFI warning for paravirt callback prototype - Clarify documentation for seq_show_option_n() usage" * tag 'hardening-v6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: (23 commits) LoadPin: Annotate struct dm_verity_loadpin_trusted_root_digest with __counted_by kallsyms: Change func signature for cleanup_symbol_name() kallsyms: Fix kallsyms_selftest failure nsproxy: Convert nsproxy.count to refcount_t integrity: Annotate struct ima_rule_opt_list with __counted_by lkdtm: Add FAM_BOUNDS test for __counted_by Compiler Attributes: counted_by: Adjust name and identifier expansion um: refactor deprecated strncpy to memcpy um: vector: refactor deprecated strncpy alpha: Replace one-element array with flexible-array member hardening: Move BUG_ON_DATA_CORRUPTION to hardening options list: Introduce CONFIG_LIST_HARDENED list_debug: Introduce inline wrappers for debug checks compiler_types: Introduce the Clang __preserve_most function attribute gcc-plugins: Rename last_stmt() for GCC 14+ selftests/harness: Actually report SKIP for signal tests x86/paravirt: Fix tlb_remove_table function callback prototype warning EISA: Replace all non-returning strlcpy with strscpy perf: Replace strlcpy with strscpy um: Remove strlcpy declaration ...
