Realtime Dynamic Binary InstrumentationDu, Mike January 2016 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / This thesis presents a novel technique and framework for decreasing instrumenta-
tion overhead in software systems that utilize dynamic binary instrumentation. First,
we introduce a lightweight networking framework combined with an easily extensible
BSON implementation as a heavy analysis routine replacement. Secondly, we bind
instrumentation and analysis threads to non-overlapping cpu cores--allowing analysis
threads to execute faster. Lastly, we utilize a lock-free buffering system to bridge the
gap between instrumentation and analysis threads, and minimize the overhead to the
instrumentation threads. Using this combination, we managed to write a dynamic
binary instrumentation tool (DBI) in Pin using Pin++ that is almost 1100 % faster
than its counterpart DBI tool with no buffering, and less than 500% slower than a
similar tool with no analysis routine.
