ufs: permit mounting of BorderWare filesystems ...
I recently had to recover some files from an old broken machine that was
running BorderWare Document Gateway. It's basically a drop in web server
for sharing files. From the look of the init process and using strings on
of a few files it seems to be based on FreeBSD 3.3.
The process turned out to be more difficult than I imagined, but to cut a
long story short BorderWare in their wisdom use a nonstandard magic number
in their UFS (ufstype=44bsd) file systems. Thus Linux refuses to mount
the file systems in order to recover the data. After a bit of hunting I
was able to make a quick fix to fs/ufs/super.c in order to detect the new
magic number.
I assume that this number is the same for all installations. It's quite
easy to find out from ufs_fs.h. The superblock sits 8k into the block
device and the magic number its 1372 bytes into the superblock struct.
