Behave or be watched: debugging with behavioral watchpoints

Content Provider ACM Digital Library
Author Goel, Ashvin Kumar, Akshay Goodman, Peter Brown, Angela Demke
Abstract Finding, understanding, and fixing bugs in an operating system is challenging. Dynamic binary translation (DBT) systems provide a powerful facility for building program analysis and debugging tools. However, DBT abstractions are too low-level and provide limited contextual information for instrumentation tools. We introduce behavioral watchpoints, a new software-based watchpoint framework that simplifies the implementation of DBT-based program analysis and debugging tools. Behavioral watchpoints extend the traditional approach of using a DBT system by providing context-specific information at the instruction level and specializing instrumentation to individual data structures. We describe four applications developed using our watchpoint framework: detecting buffer overflows, detecting read-before-write and memory freeing bugs, detecting memory leaks and enforcing fine-grained memory access policies. We implemented behavioral watchpoints using Granary, a new DBT framework. We show that the overheads are reasonable for their intended use in analyzing and debugging kernel modules.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
