Abstract

See full text

A technique allows for memory bounds checking for dynamically generated code by using transactional memory support in a processor. The memory bounds checking includes creating output code, identifying read-only memory regions in the output code and creating a map that is provided to a security monitoring thread. The security monitoring thread executes as a transaction and determines if a transactional conflict occurs to the read-only memory region during parallel execution of a monitored thread in the output code.
