Its approach is to run large amount of tests in background. During every test a program (e.g. qemu-img) is called to read or modify an invalid test image. A test image has valid inner structure defined by its format specification with some fields having random invalid values. Patch 1 contains documentation for the image fuzzer, patch 2 is the test runner and remaining ones relate to the image generator for qcow2 format. This patch series was created for the 'block-next' branch. v4 -> v5: Runner: * Added a warning message if a backing file failed to be created (based on the review of Fam Zheng) * Back up a test image before every test command * Fixed always logged messages of a program under test * Added a warning message if a wrong name of a program under test is specified * Made offset and length qemu-io arguments multiple of a sector size * Print all errors to stderr Layout: * Fixed estimation of the feature name table length Fuzz: * Added fuzzing vector for 8bit values Overall: * Missed white spaces (based on reviews of Fam Zheng and Stefan Hajnoczi) * Simplified attribute calls (based on the review of Stefan Hajnoczi) Maria Kustova (5): docs: Specification for the image fuzzer runner: Tool for fuzz tests execution fuzz: Fuzzing functions for qcow2 images layout: Generator of fuzzed qcow2 images package: Public API for image-fuzzer/runner/runner.py tests/image-fuzzer/docs/image-fuzzer.txt | 239 ++++++++++++++++++ tests/image-fuzzer/qcow2/__init__.py | 1 + tests/image-fuzzer/qcow2/fuzz.py | 327 +++++++++++++++++++++++++ tests/image-fuzzer/qcow2/layout.py | 369 ++++++++++++++++++++++++++++ tests/image-fuzzer/runner/runner.py | 405 +++++++++++++++++++++++++++++++ 5 files changed, 1341 insertions(+) create mode 100644 tests/image-fuzzer/docs/image-fuzzer.txt create mode 100644 tests/image-fuzzer/qcow2/__init__.py create mode 100644 tests/image-fuzzer/qcow2/fuzz.py create mode 100644 tests/image-fuzzer/qcow2/layout.py create mode 100755 tests/image-fuzzer/runner/runner.py -- 1.9.3
