4.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Richard <rich...@aaazen.com> commit 223220356d5ebc05ead9a8d697abb0c0a906fc81 upstream. The code in block/partitions/msdos.c recognizes FreeBSD, OpenBSD and NetBSD partitions and does a reasonable job picking out OpenBSD and NetBSD UFS subpartitions. But for FreeBSD the subpartitions are always "bad". Kernel: <bsd:bad subpartition - ignored Though all 3 of these BSD systems use UFS as a file system, only FreeBSD uses relative start addresses in the subpartition declarations. The following patch fixes this for FreeBSD partitions and leaves the code for OpenBSD and NetBSD intact: Signed-off-by: Richard Narron <comet.berke...@gmail.com> Reviewed-by: Christoph Hellwig <h...@lst.de> Signed-off-by: Jens Axboe <ax...@fb.com> Signed-off-by: Greg Kroah-Hartman <gre...@linuxfoundation.org> --- block/partitions/msdos.c | 2 ++ 1 file changed, 2 insertions(+) --- a/block/partitions/msdos.c +++ b/block/partitions/msdos.c @@ -300,6 +300,8 @@ static void parse_bsd(struct parsed_part continue; bsd_start = le32_to_cpu(p->p_offset); bsd_size = le32_to_cpu(p->p_size); + if (memcmp(flavour, "bsd\0", 4) == 0) + bsd_start += offset; if (offset == bsd_start && size == bsd_size) /* full parent partition, we have it already */ continue;
