2020-12-22Merge branch 'akpm' (patches from Andrew)Linus Torvalds1-89/+173
Merge KASAN updates from Andrew Morton. This adds a new hardware tag-based mode to KASAN. The new mode is similar to the existing software tag-based KASAN, but relies on arm64 Memory Tagging Extension (MTE) to perform memory and pointer tagging (instead of shadow memory and compiler instrumentation). By Andrey Konovalov and Vincenzo Frascino. * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (60 commits) kasan: update documentation kasan, mm: allow cache merging with no metadata kasan: sanitize objects when metadata doesn't fit kasan: clarify comment in __kasan_kfree_large kasan: simplify assign_tag and set_tag calls kasan: don't round_up too much kasan, mm: rename kasan_poison_kfree kasan, mm: check kasan_enabled in annotations kasan: add and integrate kasan boot parameters kasan: inline (un)poison_range and check_invalid_free kasan: open-code kasan_unpoison_slab kasan: inline random_tag for HW_TAGS kasan: inline kasan_reset_tag for tag-based modes kasan: remove __kasan_unpoison_stack kasan: allow VMAP_STACK for HW_TAGS mode kasan, arm64: unpoison stack only with CONFIG_KASAN_STACK kasan: introduce set_alloc_info kasan: rename get_alloc/free_info kasan: simplify quarantine_put call site kselftest/arm64: check GCR_EL1 after context switch ...

2020-12-22kasan: rename KASAN_SHADOW_* to KASAN_GRANULE_*Andrey Konovalov1-1/+1
This is a preparatory commit for the upcoming addition of a new hardware tag-based (MTE-based) KASAN mode. The new mode won't be using shadow memory, but will still use the concept of memory granules. Each memory granule maps to a single metadata entry: 8 bytes per one shadow byte for generic mode, 16 bytes per one shadow byte for software tag-based mode, and 16 bytes per one allocation tag for hardware tag-based mode. Rename KASAN_SHADOW_SCALE_SIZE to KASAN_GRANULE_SIZE, and KASAN_SHADOW_MASK to KASAN_GRANULE_MASK. Also use MASK when used as a mask, otherwise use SIZE. No functional changes.

Make each UBSAN option individually selectable and remove UBSAN_MISC which no longer has any purpose. Add help text for each Kconfig, and include a reference to the Clang sanitizer documentation. Disable unsigned overflow by default (not available with GCC and makes x86 unbootable with Clang). Disable unreachable when objtool is in use (redundant and confuses things: instrumentation appears at unreachable locations).

usage.rst goes into a detailed section about faking out classes, but currently lacks wording about how one might idiomatically test a range of inputs. Add a new chapter for "Common Patterns" and group "Isolating behvaior" and this new section under there. Give an example of how one might test a hash function via macros/helper funcs and a table-driven test and very briefly discuss pros and cons. Also highlight the KUNIT_EXPECT_*_MSG() variants (that aren't mentioned elsewhere [1]) which are particularly useful in these situations. It is also criminally underused at the moment, only appearing in 2 tests (both written by people involved in KUnit).

git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest Pull kselftest updates from Shuah Khan: - speed up headers_install done during selftest build - add generic make nesting support - add support to select individual tests: Selftests build/install generates run_kselftest.sh script to run selftests on a target system. Currently the script doesn't have support for selecting individual tests. Add support for it. With this enhancement, user can select test collections (or tests) individually. e.g: run_kselftest.sh -c seccomp -t timers:posix_timers -t timers:nanosleep Additionally adds a way to list all known tests with "-l", usage with "-h", and perform a dry run without running tests with "-n". * tag 'linux-kselftest-next-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest: doc: dev-tools: kselftest.rst: Update examples and paths selftests/run_kselftest.sh: Make each test individually selectable selftests: Extract run_kselftest.sh and generate stand-alone test list selftests: Add missing gitignore entries selftests: more general make nesting support selftests: use "$(MAKE)" instead of "make" for headers_install

Which Sphinx 3, :c:type: can't be used anymore for structs, as this should be used only for typedefs. Rely on automarkup.py for struct references. This file has an special case, though: it uses the tag also to point to an array. Let's use, instead, :c:expr: for such purpose, as it should do the right thing. This should fix this warning: ./Documentation/dev-tools/kgdb.rst:875: WARNING: Unparseable C cross-reference: 'kdb_poll_funcs[]' Invalid C declaration: Expected end of definition.
