This tutorial will present the DynamoRIO tool platform and describe how to use its API to build custom tools that utilize dynamic code manipulation for instrumentation, profiling, analysis, optimization, introspection, security, and more. The DynamoRIO tool platform was first released to the public in June 2002 and has since been used by many researchers to develop systems ranging from taint tracking to prefetch optimization. DynamoRIO is publicly available in open source form and targets Windows, Linux, and Mac on x86 and Linux on ARM.

The tutorial will cover the following topics:

• DynamoRIO API: an overview of the full range of DynamoRIO’s powerful API, which abstracts away the details of the underlying infrastructure and allows the tool builder to concentrate on analyzing or modifying the application’s runtime code stream. It includes both high-level features for quick prototyping and low-level features for full control over instrumentation.
• DynamoRIO system overview: a brief description of how DynamoRIO works under the covers.
• Description of tools provided with the DynamoRIO package, including the Dr. Memory memory debugging tool, the DrCov code coverage tool, and the DrStrace Windows system call tracing tool.
• Sample tool starting points for building new tools
• Advanced topics when building sophisticated tools
