Based on : https://github.com/askac/dumpifs , but modified to support IFS, ImageFS and HBCIFS (Harmon Becker Compressed IFS) files.
dump_hbcifs will loop through the firmware file looking for supported header types, and if found will process the sub-section. At the end of the sub-section, it will continue to process the firmware file until it reaches EOF.
This process is helpful for multi-section firmware files used in QNX vehicle firmware files, which store the pre-boot, boot, and root separately. If the flag to extract files (-x) is passed to the program along with a directory (-d DIR), it will extract all files across all sections to the same DIR.
CMake links against LZO, UCL and OpenSSL (for MD5). If you install this on a typical user workstation, you will need the "-devel" package.
Examples: "./dump_hbcifs FILENAME.bin" <-- List the files in FILENAME.bin "./dump_hbcifs FILENAME.bin -d DIR -x" <-- Extract all files in FILENAME.bin and put them in directory DIR [-mvxbzh -u FILE] [-f FILE] image_file_system_file [-d DIR] -b Extract to basenames of files -u FILE Save a copy of the uncompressed image as FILE -v Verbose -x Extract files -m Display MD5 Checksum -f FILE Extract named FILE -d DIR Extract files to directory DIR -z *** NOT RECOMMENDED *** Disable the zero check while searching for the startup header. This option should be avoided as it makes the search for the startup header less reliable. -h Display this help message [Lines have been removed with "..." to shorten output unnecessary for understanding]
