[PATCHv2] selftests/net: skip psock_tpacket test if KALLSYMS was not enabled
The psock_tpacket test will need to access /proc/kallsyms, this would require the kernel config CONFIG_KALLSYMS to be enabled first. Apart from adding CONFIG_KALLSYMS to the net/config file here, check the file existence to determine if we can run this test will be helpful to avoid a false-positive test result when testing it directly with the following commad against a kernel that have CONFIG_KALLSYMS disabled: make -C tools/testing/selftests TARGETS=net run_tests Signed-off-by: Po-Hsu Lin --- tools/testing/selftests/net/config| 1 + tools/testing/selftests/net/run_afpackettests | 14 +- 2 files changed, 10 insertions(+), 5 deletions(-) diff --git a/tools/testing/selftests/net/config b/tools/testing/selftests/net/config index 4740404..3dea2cb 100644 --- a/tools/testing/selftests/net/config +++ b/tools/testing/selftests/net/config @@ -25,3 +25,4 @@ CONFIG_NF_TABLES_IPV6=y CONFIG_NF_TABLES_IPV4=y CONFIG_NFT_CHAIN_NAT_IPV6=m CONFIG_NFT_CHAIN_NAT_IPV4=m +CONFIG_KALLSYMS=y diff --git a/tools/testing/selftests/net/run_afpackettests b/tools/testing/selftests/net/run_afpackettests index ea5938e..8b42e8b 100755 --- a/tools/testing/selftests/net/run_afpackettests +++ b/tools/testing/selftests/net/run_afpackettests @@ -21,12 +21,16 @@ fi echo "" echo "running psock_tpacket test" echo "" -./in_netns.sh ./psock_tpacket -if [ $? -ne 0 ]; then - echo "[FAIL]" - ret=1 +if [ -f /proc/kallsyms ]; then + ./in_netns.sh ./psock_tpacket + if [ $? -ne 0 ]; then + echo "[FAIL]" + ret=1 + else + echo "[PASS]" + fi else - echo "[PASS]" + echo "[SKIP] CONFIG_KALLSYMS not enabled" fi echo "" -- 2.7.4
