It is enabled with a -fsanitize flag. iotests are currently disabled when -fsanitize options is used, with the exception of SafeStack. This patch implements a generic filtering mechanism to allow iotests with a set of known-to-be-safe -fsanitize option. Then mark SafeStack and the new options used for cfi-icall safe for iotests Signed-off-by: Daniele Buono --- tests/check-block.sh | 18 +++++++++++------- 1 file changed, 11 insertions(+), 7 deletions(-) diff --git a/tests/check-block.sh b/tests/check-block.sh index 8e29c868e5..7691213bd9 100755 --- a/tests/check-block.sh +++ b/tests/check-block.sh @@ -21,14 +21,18 @@ if grep -q "CONFIG_GPROF=y" config-host.mak 2>/dev/null ; then exit 0 fi -# Disable tests with any sanitizer except for SafeStack -CFLAGS=$( grep "CFLAGS.*-fsanitize" config-host.mak 2>/dev/null ) -SANITIZE_FLAGS="" -#Remove all occurrencies of -fsanitize=safe-stack -for i in ${CFLAGS}; do - if [ "${i}" != "-fsanitize=safe-stack" ]; then - SANITIZE_FLAGS="${SANITIZE_FLAGS} ${i}" +# Disable tests with any sanitizer except for specific ones +SANITIZE_FLAGS=$( grep "CFLAGS.*-fsanitize" config-host.mak 2>/dev/null ) +ALLOWED_SANITIZE_FLAGS="safe-stack cfi-icall sanitize-blacklist" +#Remove all occurrencies of allowed Sanitize flags +for j in ${ALLOWED_SANITIZE_FLAGS}; do + TMP_FLAGS=${SANITIZE_FLAGS} + SANITIZE_FLAGS="" + for i in ${TMP_FLAGS}; do + if ! echo ${i} | grep -q "${j}" 2>/dev/null; then + SANITIZE_FLAGS="${SANITIZE_FLAGS} ${i}" fi + done done if echo ${SANITIZE_FLAGS} | grep -q "\-fsanitize" 2>/dev/null; then # Have a sanitize flag that is not allowed, stop
