GNU and Oracle libelf implementations added support for section compression, intended to reduce the size of DWARF debug info (which might be an order of magnitude larger than the code). There are two compressed ELF section formats: 1. Old GNU - sections are renmaed to start with 'z'. Section contains a magic number, uncompressed size, and compressed data. 2. Oracle and New GNU - compressed sections use the SHF_COMPRESSED flag. The compression header contains the compression type, uncompressed size, and uncompressed alignment. The second style is preferred and this change implements only that one.
