Embedding and patching integrity information in a program file having relocatable file sections

摘要

Methods and apparatuses enable embedding integrity manifest information into a program in volatile memory. Instead of having fixed integrity manifest information that cannot be changed after compilation, a file of a format supporting relocatable file sections can store the integrity manifest information for a program. The integrity manifest information can be modified in-line, while the file is loaded in volatile memory, and the information stored to disk for later re-use. The program and its associated file can include a modifiable integrity manifest indicator that provides the location and size of the integrity manifest, and can be changed as appropriate. The indicator can be passed to a service processor to indicate the integrity manifest to the service processor.
