Instrumentation is inline and covers vmalloc too. SLUB_RCU_DEBUG lets it see a use after free in a SLAB_TYPESAFE_BY_RCU cache as well; the generic layer has it off, as it is of no use without KASAN. The KASAN self-test stays out. It makes bad accesses on purpose and expects their reports on the console, where the hci-kunit test counts any report as a failure of the run. What it checks is KASAN itself, not our code. SLUB_DEBUG_ON stays off: KASAN catches what its redzones and poisoning would, and at the moment of the access. https://virtuozzo.atlassian.net/browse/VSTOR-143636 https://virtuozzo.atlassian.net/browse/VSTOR-148112 Feature: KUnit tests on User Mode Linux Co-developed-by: Eva Kurchatova Signed-off-by: Konstantin Khorenko --- redhat/configs/custom-overrides/generic/um/CONFIG_KASAN | 1 + redhat/configs/custom-overrides/generic/um/CONFIG_KASAN_GENERIC | 1 + redhat/configs/custom-overrides/generic/um/CONFIG_KASAN_INLINE | 1 + redhat/configs/custom-overrides/generic/um/CONFIG_KASAN_KUNIT_TEST | 1 + redhat/configs/custom-overrides/generic/um/CONFIG_KASAN_OUTLINE | 1 + redhat/configs/custom-overrides/generic/um/CONFIG_KASAN_VMALLOC | 1 + redhat/configs/custom-overrides/generic/um/CONFIG_SLUB_RCU_DEBUG | 1 + 7 files changed, 7 insertions(+) diff --git a/redhat/configs/custom-overrides/generic/um/CONFIG_KASAN b/redhat/configs/custom-overrides/generic/um/CONFIG_KASAN new file mode 100644 index 0000000000000..4d920992d7c88 --- /dev/null +++ b/redhat/configs/custom-overrides/generic/um/CONFIG_KASAN @@ -0,0 +1 @@ +CONFIG_KASAN=y diff --git a/redhat/configs/custom-overrides/generic/um/CONFIG_KASAN_GENERIC b/redhat/configs/custom-overrides/generic/um/CONFIG_KASAN_GENERIC new file mode 100644 index 0000000000000..1c58d0d4a67d6 --- /dev/null +++ b/redhat/configs/custom-overrides/generic/um/CONFIG_KASAN_GENERIC @@ -0,0 +1 @@ +CONFIG_KASAN_GENERIC=y diff --git a/redhat/configs/custom-overrides/generic/um/CONFIG_KASAN_INLINE b/redhat/configs/custom-overrides/generic/um/CONFIG_KASAN_INLINE new file mode 100644 index 0000000000000..80f3231193560 --- /dev/null +++ b/redhat/configs/custom-overrides/generic/um/CONFIG_KASAN_INLINE @@ -0,0 +1 @@ +CONFIG_KASAN_INLINE=y diff --git a/redhat/configs/custom-overrides/generic/um/CONFIG_KASAN_KUNIT_TEST b/redhat/configs/custom-overrides/generic/um/CONFIG_KASAN_KUNIT_TEST new file mode 100644 index 0000000000000..c3842ac36b18c --- /dev/null +++ b/redhat/configs/custom-overrides/generic/um/CONFIG_KASAN_KUNIT_TEST @@ -0,0 +1 @@ +# CONFIG_KASAN_KUNIT_TEST is not set diff --git a/redhat/configs/custom-overrides/generic/um/CONFIG_KASAN_OUTLINE b/redhat/configs/custom-overrides/generic/um/CONFIG_KASAN_OUTLINE new file mode 100644 index 0000000000000..9b97879cd3adc --- /dev/null +++ b/redhat/configs/custom-overrides/generic/um/CONFIG_KASAN_OUTLINE @@ -0,0 +1 @@ +# CONFIG_KASAN_OUTLINE is not set diff --git a/redhat/configs/custom-overrides/generic/um/CONFIG_KASAN_VMALLOC b/redhat/configs/custom-overrides/generic/um/CONFIG_KASAN_VMALLOC new file mode 100644 index 0000000000000..290120758d0b0 --- /dev/null +++ b/redhat/configs/custom-overrides/generic/um/CONFIG_KASAN_VMALLOC @@ -0,0 +1 @@ +CONFIG_KASAN_VMALLOC=y diff --git a/redhat/configs/custom-overrides/generic/um/CONFIG_SLUB_RCU_DEBUG b/redhat/configs/custom-overrides/generic/um/CONFIG_SLUB_RCU_DEBUG new file mode 100644 index 0000000000000..6cdbbe398fc2e --- /dev/null +++ b/redhat/configs/custom-overrides/generic/um/CONFIG_SLUB_RCU_DEBUG @@ -0,0 +1 @@ +CONFIG_SLUB_RCU_DEBUG=y -- 2.43.0 _______________________________________________ Devel mailing list Devel@openvz.org https://lists.openvz.org/mailman/listinfo/devel
