bouyer bacd71f681 Check the number of cylinder group summary area against MAXCSBUFS. fsck and 
the kernel will happilly trash data after fs_csp[] in the superblock with
a large number of cylinder group.

wrstuden 398c91fa04 Adjust column-sizing code to keep output in 76 character lines, so output 
doesn't wrap in sysinst.

wrstuden 6735cc1a4c Make newfs's spare superblock output nicer. Figure out how wide the 
largest block number will be, and make the columns wide enough for it. Then
make enough columns to fit in an 80 character window.

Samples: small end & faked up values:

super-block backups (for fsck -b #) at:
   32,  176,  272,  416,  512,  656,  752,  896,  992, 1136, 1232, 1376, 1472,

For a 155 GB fs we have:

Now it actually looks like someone's thought about making large fs's. :-)

wrstuden f2c170eda0 Modify newfs so that the root node (and lost+found dir, if created) 
of the new fs has uid.gid equal to the euid.egid of the process
which made it. This change permits users who have write access to
a device (say a floppy) to create a filesystem that, when mounted,
they have write access to.

This change closes PR bin/5990 from jbernard@ox.mines.edu, and is also the
change requested in PR bin/6276 from "Charles M. Hannum" <mycroft@netbsd.org>
 1999-03-16 21:52:34 +00:00
wrstuden 988bdf8e19 Modify how the byteswapping of the cylinder summaries is handled. If we 
need to swap, allocate a buffer for the swapped summaries rather than using
writebuf. The latter is fixed at 64k, which is only enough room to hold
4096 summaries. Creating an fs with more results in a buffer overrun.

First noted by Matt Jacob mjacob@netbsd.org, and fixed by Albeaus
Bayucan, bayucan@nas.nasa.gov. Minor mods by me.

unnecessary pointer casts.

drochner 55f4357866 Make "mount_mfs" behave synchronously - don't exit before the mount is 
done. This has 2 advantages:
-The calling process can rely on the mounted filesystem.
-We get error messages if the mount system call fails.
