section alignnment of 16 bytes for amd64 and this breaks file(1). Before: ./cp: ELF 64-bit LSB executable, AMD x86-64, version 1 (FreeBSD), for \ FreeBSD 127.7.9, statically linked, stripped after: ^^^^^^^ ./ls: ELF 64-bit LSB executable, AMD x86-64, version 1 (FreeBSD), for \ FreeBSD 5.0.1, dynamically linked (uses shared libs), stripped The reason for this is that the NOTE sections are not contiguous internally. If the note section has an alignment of 16, then anything that looks for the data is supposed to round up the payload start to the next multiple of the alignment. But FreeBSD/amd64 broke because the structure is declared as a single structure, not a (header,payload) group, where the payload had an explicit alignment roundup. The alternative is to change things like file(1) to ignore the ELF payload alignment rules for the PT_NOTE section only for FreeBSD. |
