Palmer Dabbelt 5835437609 Merge patch series "riscv: Improve KASAN coverage to fix unit tests" ... Samuel Holland <samuel.holland@sifive.com> says: This series fixes two areas where uninstrumented assembly routines caused gaps in KASAN coverage on RISC-V, which were caught by KUnit tests. The KASAN KUnit test suite passes after applying this series. This series fixes the following test failures: # kasan_strings: EXPECTATION FAILED at mm/kasan/kasan_test.c:1520 KASAN failure expected in "kasan_int_result = strcmp(ptr, "2")", but none occurred # kasan_strings: EXPECTATION FAILED at mm/kasan/kasan_test.c:1524 KASAN failure expected in "kasan_int_result = strlen(ptr)", but none occurred not ok 60 kasan_strings # kasan_bitops_generic: EXPECTATION FAILED at mm/kasan/kasan_test.c:1531 KASAN failure expected in "set_bit(nr, addr)", but none occurred # kasan_bitops_generic: EXPECTATION FAILED at mm/kasan/kasan_test.c:1533 KASAN failure expected in "clear_bit(nr, addr)", but none occurred # kasan_bitops_generic: EXPECTATION FAILED at mm/kasan/kasan_test.c:1535 KASAN failure expected in "clear_bit_unlock(nr, addr)", but none occurred # kasan_bitops_generic: EXPECTATION FAILED at mm/kasan/kasan_test.c:1536 KASAN failure expected in "__clear_bit_unlock(nr, addr)", but none occurred # kasan_bitops_generic: EXPECTATION FAILED at mm/kasan/kasan_test.c:1537 KASAN failure expected in "change_bit(nr, addr)", but none occurred # kasan_bitops_generic: EXPECTATION FAILED at mm/kasan/kasan_test.c:1543 KASAN failure expected in "test_and_set_bit(nr, addr)", but none occurred # kasan_bitops_generic: EXPECTATION FAILED at mm/kasan/kasan_test.c:1545 KASAN failure expected in "test_and_set_bit_lock(nr, addr)", but none occurred # kasan_bitops_generic: EXPECTATION FAILED at mm/kasan/kasan_test.c:1546 KASAN failure expected in "test_and_clear_bit(nr, addr)", but none occurred # kasan_bitops_generic: EXPECTATION FAILED at mm/kasan/kasan_test.c:1548 KASAN failure expected in "test_and_change_bit(nr, addr)", but none occurred not ok 61 kasan_bitops_generic Samuel Holland (2): riscv: Omit optimized string routines when using KASAN riscv: Enable bitops instrumentation arch/riscv/include/asm/bitops.h | 43 ++++++++++++++++++--------------- arch/riscv/include/asm/string.h | 2 ++ arch/riscv/kernel/riscv_ksyms.c | 3 --- arch/riscv/lib/Makefile | 2 ++ arch/riscv/lib/strcmp.S | 1 + arch/riscv/lib/strlen.S | 1 + arch/riscv/lib/strncmp.S | 1 + arch/riscv/purgatory/Makefile | 2 ++ 8 files changed, 32 insertions(+), 23 deletions(-) * b4-shazam-merge: riscv: Enable bitops instrumentation riscv: Omit optimized string routines when using KASAN Link: https://lore.kernel.org/r/20240801033725.28816-1-samuel.holland@sifive.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>		2024-09-19 01:10:44 -07:00
