67b23e6043 getopt_ulflags -> getopt32.
It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.

5a62284972 this applet needlessly big! TODO: bb_getopt_ulflags()
- use atol for the offset, which is always in bytes. Small step in eventually dropping bb_xparse_number().

ce88793698 When you went "losetup -d /dev/loop0 /dev/loop1" the error message was strange. 2005-12-21 17:00:25 +00:00

1d589b2e2d Fix losetup so that it A) actually works again, B) has much better error
messages, C) can show the current association (if any) when called
with only one argument.  Update the documentation a lot too.

Remind me to add a test suite for this thing.  I think I've figured out
how to handle root-only testsuites...

6a6798b8e4 Major rewrite of mount, umount, losetup. Untangled lots of code, shrunk
things down a bit, fixed a number of funky corner cases, added support for
several new features (things like mount --move, mount --bind, lazy unounts,
automatic detection of loop mounts, and so on).  Probably broke several
other things, but it's fixable.  (Bang on it, tell me what doesn't work for
you...)

Note: you no longer need to say "-o loop".  It does that for you when
necessary.

Still need to add "user mount" support, which involves making mount suid.  Not
too hard to do under the new infrastructure, just haven't done it yet...

The previous code had the following notes, that belong in the version
control comments:

- * 3/21/1999   Charles P. Wright <cpwright@cpwright.com>
- *             searches through fstab when -a is passed
- *             will try mounting stuff with all fses when passed -t auto
- *
- * 1999-04-17  Dave Cinege...Rewrote -t auto. Fixed ro mtab.
- *
- * 1999-10-07  Erik Andersen <andersen@codepoet.org>.
- *              Rewrite of a lot of code. Removed mtab usage (I plan on
- *              putting it back as a compile-time option some time),
- *              major adjustments to option parsing, and some serious
- *              dieting all around.
- *
- * 1999-11-06  mtab support is back - andersee
- *
- * 2000-01-12   Ben Collins <bcollins@debian.org>, Borrowed utils-linux's
- *              mount to add loop support.
- *
- * 2000-04-30  Dave Cinege <dcinege@psychosis.com>
- *             Rewrote fstab while loop and lower mount section. Can now do
- *             single mounts from fstab. Can override fstab options for single
- *             mount. Common mount_one call for single mounts and 'all'. Fixed
- *             mtab updating and stale entries. Removed 'remount' default.

When using "losetup" the device is always setup as Read-Only.

(I have only tested with the -o flag, but looking at the code the
 problem seems general)

The problem is the "opt" variable in "losetup.c" that is reused in
the "set_loop()" call. Clear it before the call and everything is OK;

  opt = 0;         /* <-------- added line */
  if (delete)
    return del_loop (argv[optind]) ? EXIT_SUCCESS : EXIT_FAILURE;
  else
    return set_loop (argv[optind], argv[optind + 1], offset, &opt)
      ? EXIT_FAILURE : EXIT_SUCCESS;
}
