## Sanitizers
|
|
|
|
Fuzzers are usualy built with one or more [sanitizer](https://github.com/google/sanitizers) enabled.
|
|
You can select sanitizer configuration by specifying `$SANITIZER` build environment varible using `-e` option:
|
|
|
|
```bash
|
|
python infra/helper.py build_fuzzers -e SANITIZER=undefined json
|
|
```
|
|
|
|
Supported sanitizers:
|
|
|
|
| `$SANITIZER` | Description
|
|
| ------------ | ----------
|
|
| `address` *(default)* | [Address Sanitizer](https://github.com/google/sanitizers/wiki/AddressSanitizer) with [Leak Sanitizer](https://github.com/google/sanitizers/wiki/AddressSanitizerLeakSanitizer).
|
|
| `undefined` | [Undefined Behavior Sanitizer](http://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html).
|
|
| `memory` | [Memory Sanitizer](https://github.com/google/sanitizers/wiki/MemorySanitizer). *NOTE: It is critical that you build __all__ the code in your program (including libraries it uses) with memory sanitizer.*
|
|
|
|
Compiler flag values for predefined configurations are specified in the [Dockerfile](../base-images/base-builder/Dockerfile).
|
|
These flags can be overriden by specifying `$SANITIZER_FLAGS` directly.
|
|
|
|
You can choose which configurations to automatically run your fuzzers with in `project.yaml` file ([sqlite3](../../../projects/sqlite3/project.yaml)):
|
|
|
|
```yaml
|
|
sanitizers:
|
|
- address
|
|
- undefined
|
|
```
