From 2a4e4d555d1bd6043b556c0d1ad0fdd516bae0a5 Mon Sep 17 00:00:00 2001 From: Mark Stemm Date: Tue, 26 Oct 2021 17:08:33 -0700 Subject: [PATCH] Add automated tests for plugins Test infrastructure and sample confs/rules/traces for plugins automated tests: New test cases are in falco_tests_plugins.yaml and cover: - Listing plugins and fields when plugins are loaded. - Basic cloudtrail + json plugin on a fake cloudtrail json file and a sample rule that uses both plugins. - Conflicts between source/extractor plugins - Incompatible plugin api - Wrong plugin path - Checking for warnings when reading rules with unnown sources (e.g. when plugins are not loaded) Some test-only plugins written in C are in test/plugins and built on the fly. (They aren't included in packages of course). The test framework needed some small changes to handle these tests: - Add a mode to not check detection counts at all (for --list/--list-plugins) - addl_cmdline_opts to allow specifying --list/--list-plugins - Using DOTALL when matching stderr/stdout (allows multi-line matches more easily) Signed-off-by: Mark Stemm --- test/CMakeLists.txt | 5 +- test/confs/plugins/CMakeLists.txt | 16 ++ .../cloudtrail_json_create_instances.yaml | 14 ++ ...dtrail_json_create_instances_bigevent.yaml | 14 ++ .../plugins/incompatible_extract_sources.yaml | 14 ++ .../plugins/incompatible_plugin_api.yaml | 10 ++ .../plugins/multiple_source_plugins.yaml | 15 ++ .../plugins/overlap_extract_sources.yaml | 17 ++ test/confs/plugins/wrong_plugin_path.yaml | 10 ++ test/falco_test.py | 13 +- test/falco_tests_plugins.yaml | 106 ++++++++++++ test/plugins/CMakeLists.txt | 13 ++ test/plugins/incompat_api.cpp | 28 +++ test/plugins/test_extract.cpp | 116 +++++++++++++ test/plugins/test_source.cpp | 161 ++++++++++++++++++ .../plugins/cloudtrail_create_instances.yaml | 6 + .../cloudtrail_incompat_plugin_version.yaml | 10 ++ test/run_regression_tests.sh | 2 +- test/trace_files/CMakeLists.txt | 3 +- test/trace_files/plugins/CMakeLists.txt | 16 ++ .../plugins/alice_start_instances.json | 31 ++++ .../alice_start_instances_bigevent.json | 32 ++++ 22 files changed, 644 insertions(+), 8 deletions(-) create mode 100644 test/confs/plugins/CMakeLists.txt create mode 100644 test/confs/plugins/cloudtrail_json_create_instances.yaml create mode 100644 test/confs/plugins/cloudtrail_json_create_instances_bigevent.yaml create mode 100644 test/confs/plugins/incompatible_extract_sources.yaml create mode 100644 test/confs/plugins/incompatible_plugin_api.yaml create mode 100644 test/confs/plugins/multiple_source_plugins.yaml create mode 100644 test/confs/plugins/overlap_extract_sources.yaml create mode 100644 test/confs/plugins/wrong_plugin_path.yaml create mode 100644 test/falco_tests_plugins.yaml create mode 100644 test/plugins/CMakeLists.txt create mode 100644 test/plugins/incompat_api.cpp create mode 100644 test/plugins/test_extract.cpp create mode 100644 test/plugins/test_source.cpp create mode 100644 test/rules/plugins/cloudtrail_create_instances.yaml create mode 100644 test/rules/plugins/cloudtrail_incompat_plugin_version.yaml create mode 100644 test/trace_files/plugins/CMakeLists.txt create mode 100644 test/trace_files/plugins/alice_start_instances.json create mode 100644 test/trace_files/plugins/alice_start_instances_bigevent.json diff --git a/test/CMakeLists.txt b/test/CMakeLists.txt index 1339e226..f01777f4 100644 --- a/test/CMakeLists.txt +++ b/test/CMakeLists.txt @@ -1,4 +1,7 @@ add_subdirectory(trace_files) add_custom_target(test-trace-files ALL) -add_dependencies(test-trace-files trace-files-base-scap trace-files-psp trace-files-k8s-audit) \ No newline at end of file +add_dependencies(test-trace-files trace-files-base-scap trace-files-psp trace-files-k8s-audit trace-files-plugins) + +add_subdirectory(plugins) +add_subdirectory(confs/plugins) diff --git a/test/confs/plugins/CMakeLists.txt b/test/confs/plugins/CMakeLists.txt new file mode 100644 index 00000000..7f582cb2 --- /dev/null +++ b/test/confs/plugins/CMakeLists.txt @@ -0,0 +1,16 @@ +# This list is populated at cmake time, not build time +file(GLOB test_conf_files + "${CMAKE_CURRENT_SOURCE_DIR}/*.yaml") + +foreach(conf_file_path ${test_conf_files}) + get_filename_component(conf_file ${conf_file_path} NAME) + add_custom_target(test-conf-${conf_file} ALL + DEPENDS ${CMAKE_CURRENT_BINARY_DIR}/${conf_file}) + add_custom_command(OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/${conf_file} + COMMAND sed -e s!BUILD_DIR!${CMAKE_BINARY_DIR}! < ${CMAKE_CURRENT_SOURCE_DIR}/${conf_file} > ${CMAKE_CURRENT_BINARY_DIR}/${conf_file} + DEPENDS ${CMAKE_CURRENT_SOURCE_DIR}/${conf_file}) + list(APPEND PLUGINS_CONF_FILES_TARGETS test-conf-${conf_file}) +endforeach() + +add_custom_target(conf-files-plugins ALL) +add_dependencies(conf-files-plugins ${PLUGINS_CONF_FILES_TARGETS}) diff --git a/test/confs/plugins/cloudtrail_json_create_instances.yaml b/test/confs/plugins/cloudtrail_json_create_instances.yaml new file mode 100644 index 00000000..9345566d --- /dev/null +++ b/test/confs/plugins/cloudtrail_json_create_instances.yaml @@ -0,0 +1,14 @@ +stdout_output: + enabled: true + +plugins: + -
