This patch series introduces the image fuzzer, a tool for stability and reliability testing. 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. v1 -> v2: * refactored qcow2/layout module * added support of external fuzzer configurations * fixed wrong string truncation in qcow2/fuzz module * fixed documentation typos and ambiguities (based on Eric Blake comments) * updated documentation with the fuzzer configuration * add LICENSE file (based on Eric Blake comments) Maria Kustova (6): 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 image-fuzzer: GPLv2 license file tests/image-fuzzer/LICENSE | 339 +++++++++++++++++++++++++++++++ tests/image-fuzzer/docs/fuzzer.conf | 37 ++++ tests/image-fuzzer/docs/image-fuzzer.txt | 216 ++++++++++++++++++++ tests/image-fuzzer/qcow2/__init__.py | 1 + tests/image-fuzzer/qcow2/fuzz.py | 328 ++++++++++++++++++++++++++++++ tests/image-fuzzer/qcow2/layout.py | 319 +++++++++++++++++++++++++++++ tests/image-fuzzer/runner/runner.py | 290 ++++++++++++++++++++++++++ 7 files changed, 1530 insertions(+) create mode 100644 tests/image-fuzzer/LICENSE create mode 100644 tests/image-fuzzer/docs/fuzzer.conf 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
