loopback device + crypto = crash on 2.6.0-test7 ?

loopback device + crypto = crash on 2.6.0-test7 ?

[Soeren Sonnenburg]

Hi.

I wanted to setup a blowfish encrypted file which is then mounted via
loopback. So I did:

losetup -e blowfish /dev/loop0 /file
Password:
mkfs -t ext3 /dev/loop0
mount /dev/loop0 /mnt
<error unknown fs type>
<from here something was seriously broken... could not reboot anymore>

system is:
Linux no 2.6.0-test7 #8 Sun Oct 26 17:00:49 CET 2003 ppc GNU/Linux

(benh rsync tree)

Did you pre-create the file? I've been doing something quite similar since
about test6, although I use ext2 and aes I don't suspect that matters. But
I did preallocate the file with dd first. I assume you did that, since you
don't give a size in mkfs, but better to mention it.

I've run both dead stock test releases, -mm, and most recently a mix of
Nick and Con scheduler and io patches.

I'm seeing something similar, but in my case, mke2fs already crashes.

Mine ist -test9 on x86.

Have you found a solution in the meantime?

Yes... it crashes somewhen after writing to the loop device... sometimes
mkfs is enough, sometimes one has to write a bit more...

I have been using aes and not seeing this. I suppose it's unlikely that
there could be an error in the kernel crypto, but I think I'll wait and
try blowfish on a non-critical machine.

My solution has been to not use cryptofs, it crashes with whatever 
algorithm I choose :-(

I agree that something is very broken, though. Mind you, I can only 
replicate this problem on one of my machines - the other one I've tried it 
on seems to work fine. Odder still, when I compile a kernel on the machine 
which is fine and ruin said kernel on the machine which is not fine, I 
don't experience the crash.

I've attached a traced session plus the config used, may it be of use to 
someone (please! :-)

Compiler version problem? In any case it sounds as if you have a
solution for the moment.

That _really_ sounds like your "broken machine" is nothing more than a
broken compiler (or possibly binutils, but compilers tend to be more
fragile by far, so it's more likely the compiler).

What compiler versions do you have installed on the broken vs good
machines?

GCC 3.3.2 (Debian 3.3.2-3) is broken for me (binutils is 2.14.89.0.7-2).

Which compiler is recommend/known to work?  The README file mentions GCC
2.95.3, but this one has problems as well, AFAIK.

Could we see a 'gcc -V' from *both* machines, please? (and an 'as -v'
and 'ld -v' as well, just to be thorough?)

They're the same. Both boxes use Debian Sid with gcc-3.3.2. I made sure 
they were both running the same versions of gcc/binutils when I tested it. 
When I use gcc-2.95.4 (gcc version 2.95.4 20011002 Debian prerelease) on 
the "broken" machine I get a crash at the same point, but with different 
output. (not captured, due to got annoyed and gave up) I can probably spend 
an hour or so recompiling and capturing said crash if you want me to.

As for software versions (kahlua is "bad", shiraz is "good")

As you see, versions are identical on both machines - this is what had me 
baffled. Every single other thing works fine on the "bad" machine, so I 
tend to not suspect a hardware problem.

And yet the kenrel works when built on one machine?

I'd love to see what the differences are. If the .config etc are all 100%
the same, I'd like to see what "diff" reports on the generated vmlinux
files (well, to be honest, I'd need either both files on some web-site, or 
you to actually run diff and find _where_ the differences are).

Well, due to [insert long explanation] the -test8 kernel wasn't available. 
The "good" machine built a -test9, which crashed as well. *sigh* Mind you, 
there are differences between the kernel _it_ builds and the one built by 
the "bad" machine. I've uploaded a alien -t'd debian kernel packages to the 
fastest web space I have for you to have a peek, if you have some time. 
(what with lawsuits and whatnot ;-)

2.6.0-test9 built on the "good" box:
http://monolith.dnsalias.org/~cafuego/kernel-image-2.6.0-test9-kahlua.1.tgz

2.6.0-test9 built on the "bad" box:
http://monolith.dnsalias.org/~cafuego/kernel-image-2.6.0-test9-kahlua.2.tgz

More importantly though, the post from Jindrich:

When I compiled on the "bad" machine with disabled HIGHMEM, the resultant 
kernel has NO problems with cryptoloop. I can make a cryptoloop fs, mount, 
copy, unmount, remount etc. That kernel is at:
http://monolith.dnsalias.org/~cafuego/kernel-image-2.6.0-test9-kahlua.3.tgz

So I guess HIGHMEM breaks cryptoloop somehow.

I've been using 'highmem=off' until now, which provided a workaround.
Just built 2.6.1-rc1-mm2 and cryptloop+highmem works as it should now.

FYI, cryptoloop works as expected in 2.6.0-mm2 both with and without
highmem support.

A vanilla 2.6.0 ist unusable due to oopses / data corruption (don't fsck
a cryptoloop device!) (again, with and without highmem).

I hope the -mm loop fixes will be included in 2.6.1.

Re: loopback device + crypto = crash on 2.6.0-test7 ?

[Jindrich Makovicka]

I can confirm, having similar problem. I am using Debian Sid & 
2.6.0-test9, with 4Gig highmem support (1.5G physical RAM). When reading 
from cryptoloop (dd if=/dev/loop0 of=testoutput), it seems to produce 
only noise. Each run of dd produces completely different heap of 
garbage. When I disable highmem, getting rid of about 512 Megs, 
cryptoloop seems to work as expected - I can do losetup & mke2fs & mount 
& read/write files & unmount & losetup -d & again.. ad nauseam.
