9085467970 Trying to losetup a device as a regular user shouldn't result in an endless
loop, and the error messages should display correctly now.

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...

7547a6e2f6 - don't update copyright years. He might release it, but apparently will have
to update the year himself.

ff567f7943 The check for EROFS was wrong. For example, if you try to mount a filesystem
appended to an executable that's being run (yes, I'm doing this) you get
EPERM, but mounting readonly fixes it.  Doing the fallback all the time
shouldn't hurt, and is one less test.

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.

1e4dc96d61 Dear andersen:
Is the change on libbb/loop.c which you commited in 2005/1/3 effective
really?

The __GLIBC__ macro and __UCLIBC__ macro are defined in
feature.h in glibc source, so the change may not be effective.
If you want to check this with __GLIBC__, feature.h header is needed.

Some architectures(e.g. PPC series) need to include linux/posix_types.h
in stead of asm/posix_types.h, so the patch which is attached with
this mail include <linux/posix_types.h>.

0722513497 Use __kernel_old_dev_t for 2.6.x kernels 2004-08-16 08:36:28 +00:00

with a quick conversion you will see that 132608 == 0x20600
so noticed that the elif will never be matched !
Apparently there was already a try to modify this in CVS which
was reverted (it was plain wrong).

I don't know when __kernel_old_dev_t is needed, but with a 2.6.7
or a 2.6.8 this is __kernel_dev_t wich is needed.

I corrected this with the following patch but maybe older 2.6
still need __kernel_old_dev_t ?

I think this should be corrected before 1.0.

Thanks

ef8cd3be17 Make the loop support stuff be much less evil, and make it cope
with 2.6.x asm/posix_types.h, which has done singularly evil thing
by yanking __kernel_dev_t and renaming it.  The loop interface was
really poorly designed in the first place.  The new 64 bit loop
interface looks to be somewhat less horrible, too bad it is only
present in 2.6.x kernels.
