I think you can use the "fill" thing to basically add any random data to a section. So you can do something like . = ALIGN(16); .salt : AT(ADDR(.salt) - LOAD_OFFSET) { LONG(0xffaa5500); . = ALIGN(16); } =0x01234567890abcdef in the lds file, and you'll get a section that looks like this: [torvalds@i7 linux]$ objdump -h vmlinux -j .salt -s vmlinux: file format elf64-x86-64 Sections: Idx Name Size VMA LMA File off Algn 15 .salt 00000010 ffffffff8432b000 000000000432b000 0352b000 2**0 CONTENTS, ALLOC, LOAD, DATA Contents of section .salt: ffffffff8432b000 0055aaff 00123456 7890abcd ef001234 .U....4Vx......4 Now whether that is sufficient for your needs, I dunno.
