The libblkid probing functions returns the first successful result of the filesystem/RAID/PT. Unfortunately, some signatures is possible to detect by more ways or device may contains more copies (e.g. GPT). This is no problem when we wipe signatures from the device. In this case we zeroize on-device signature and re-scan for the signature (by blkid_probe_step_back()). The problem is if we want to read all permutations without the device modification (for example wipefs(8) dry run). This patch add blkid_probe_hide_range(). The function remove (zeroize) specified signature from in-memory cached buffers. If the buffer is later re-used by probing functions then the signature is invisible and we can try detect another variant of the magic string. Signed-off-by: Karel Zak <kzak@redhat.com> |
