Torsten Hilbrich posted a chroot "bug" that works on 2.2.17 and
2.2.18pre21, it's in de.comp.os.unix.networking, Subject containing
"chroot-Bug in Linux", dated 2000-11-15 20:38:38 local time (+0100).
Its Message-ID: <87bsvhgh4x.fsf_-_@myrkr.in-berlin.de>

It shows a program that saves the cwd -- open(".",...) in an open file,
then chroots to a newly made directory below that, fchdirs back to the
original open file (that is now outside the chroot) and calls upon
chdir("..").

Note that it's NOT related to the current working directory, but to an
open file outside the chroot.

Please comment.

This is known behaviour (I know Alan knows about it too), solution is to close
open directories filedescriptors before chrooting.

Everything that happens before chroot(2) is trusted, so it's secure to rely
on it to close directories first.

If this is not well documented and people doesn't know about it and so they
writes unsafe code that's another issue...

But the problem is because you can call chroot when you're already chrooted.

So what happens is--

1.  Your server closes all open directory file descriptors and chroots.
2.  Someone manages to run some exploit code in your process space which--

  1.  Makes a directory inside the current chroot jail.
  2.  Acquires a file descriptor for the root of the current chroot jail.
  3.  Chroots to the directory that was just created.
  4.  Uses this exploit to pull itself out of the second chroot jail, which 
      also breaks it out of the original chroot jail as well.

It's simply not good enough to close all directory file descriptors before chrooting.

If calling chroot once you're already in a chroot jail was disallowed, it would stop
this attack.

Only if you're root.  There are other ways to break out of a
chroot() if you're root too.

I think the problem here is that some people have the idea that chroot is 
some kind of magical security device. Thats not true at all. You can build an
environment like that if you wish by closing other directory handles and having
no suitably priviledged code in the chroot area and stuff.

I read about the BSD Jail stuff a while ago. 

It's a nice "operating system class lab project". Estimated time
needed: 40 hours.

This IS the magical security device.

Also many of people work to add to linux jail-like functionality,
which is expected to be real security tool unlike bsd jail.

I think from the same source where you read about jail
you know that jail is full of holes like colander. 8)

It's a non-problem. chroot()ing again may also be used to de-escalate
privileges, and if you want to prevent breaking out of a chroot, drop
root privileges, since chroot is a privileged call. And DO USE setuid,
not seteuid or something (otherwise the saved set-uid will bite you).

BUG: you *MUST* chdir() into the chroot jail before it does you any
good at all!

I usually recommend:

mkdir("foo");
chdir("foo");
chroot(".");

No, it wasn't a bug!  It was a demonstration.  The above code is
executed not by the application but by the *attacker* who has managed
to 0wn the existing jail.

Doing the additional chroot("foo") without already being in "foo"
basically replaces the chroot jail you *were* in, so you are now out.

The sequence I posted is just the simplest un-chroot procedure I know,
to explain why chroot cannot sandbox the superuser.

Actually, I've heard that a chrooted _non-root_ process can find another
process with the same uid that's not chrooted and can ptrace() to pull
itself out of the jail.

I'd imagine dropping CAP_SYS_PTRACE would avoid this, though.

It appears that even dropping root privileges might not be enough.

And I realize that there are a number of ways that a root process can
escape, I was mostly objecting to the assertion that chroot() was secure
because everything before the chroot call is assumed to be trusted.

Right. Once you have same uid as someone else, you have basically his
priviledges if you chooseto.

> I'd imagine dropping CAP_SYS_PTRACE would avoid this, though.

Pardon me, but CAP_SYS_PTRACE is not required for tracing processes of
same UID.

Unless I'm missing something, not all of them do. I haven't checked this
or anything, but it seems to me that all you need is a cooperating
process outside the jail, that opens some world-readable directory and
sends it to the exploit process inside the jail, which fchdir()s to
it. Of course you *do* need an AF_UNIX socket inside the jail for this,
too, so it is probably a quite unlikely attack; but if, for instance,
you reused an outside-the-jail uid *inside* the jail, and the jail had
places writable by this user... bing, no root necessary.

In that case, you are already outside. (:  Why bother with the chroot

Ok, Matti,
here's a final patch against the bonding patch I
posted
on Friday. Could you tell me if it fits your needs ?
If so, I would repost (offline) the complete one
against 2.2.18pre21. Anyway, for those curious here,
it's available at the following URL:

http://www-miaif.lip6.fr/willy/pub/linux-patches/bonding/patch-2.2.18p21-bonding-20001113.gz

this is *EXACTLY* what the old bonding driver does,
and what the new one does by default.

OK, I've read about it because Thomas Davis asked me
if I would implement it. I didn't find it usefull for
the case of a Linux server directly connected to a
router or a level X switch (x>2) because in this case
only one link is getting used. Perhaps I'm wrong, but
I think this is the major use of the current Linux
bonding driver. However, the new driver is now ready
for such an implementation.

probably, but do you have examples in mind ? if so, I
would add XOR to a next release, but I don't want to
add too much at a time. I consider this release
primarily as a bugfix (smp, security, oopses...), and
as an improvement which now supports link fail-over,
which is also a primary concern when implementing
multilinks.

yes it is compatible ! compatible doesn't mean it does
not work the same way, but it works with. Both the
cisco and linux drivers agree to receive on each of
their trunk ports, so the difference only resides in
link optimization when sending frames.

Ok, Matti. Let's keep "Etherchannel" as you proposed
and as it was documented in the Configure.help. This
patch fixes it (I won't resend the complete patch
on the LKML because 20kB is generally to big for
unconcerned people).

I won't say there are no issues, but I'd say there are
no KNOWN issues.

I know that, Constantine. But I know a few people at
work who used it (me included), and I also had a
report
from a guy in germany using it with success.
I know this is really not much, but we used to read
about problems by the past, and I haven't received
even one complaint about the new one, so I bet it's a
bit better than it was.

as always, and just like any other driver (eg: I'll
try
to take some time to make the megaraid work again on
my server).

> So if it is included, it must me marked as
experimental.

agreed.

Alan, do you consider it as a bugfix if I tell you
that
we can't get anymore oops with the new bonding code,
even in SMP ?

I've had reports of it working very well, and faster,
for a long time now and the link detection seems
completely OK now. I'd like to specially thank
Constantine Gavrilov for all the tests he has done and
the time he spent in enhancing the documentation.

Please find the patch against 2.2.18pre20 in
attachment, in case you agree.

Regards,
Willy

ISDN uses "channel bonding", not bonding. As for "Etherchannel", let us change
it to "EtherChannel" is this is how it is called.

Gee, we do not call it EtherChannel, we say CISCO calls it EtherChannel. Where
is the infringment here? Are people that paranoid or it is just me who is not
getting it?

	You missed my original point.

	I don't like to call it BONDING.

	"Bonding" is something where two (or more) channels carry data
	in between two participating systems.  Like Multilink-PPP, and
	ISDN Channel Bonding.  Often indeed data goes out somehow inter-
	leaved on the physical links.  (Like ISDN Channel Bonding supplies
	a transparent 128 kbps link instead of two 64 kbps links to the
	upper layers.)

	EtherChannel does select the link (out of the group) by forming
	XOR of source and destination MAC addresses (their lowest bytes),
	and then doing MODULO number-of-links on the result.

	So between systems A and B the flow goes via link 0, in between
	A and C it goes via link 1.  Add there client system D, and it
	may end up into either of the links.

	|-----------|                |------|
	|    A      |-----link-0-----| SW   |---[B]
	|           |-----link-1-----| with |---[C]
	|-----------|                |EthChn|---[D]
	                             |------|


	This gives improved throughput on congested links in between
	two switches, or major server and core switches, while preserving
	data order over the links.

	Blind bonding-type "throw packets on links 0 and 1" MAY end up
	sending ethernet frames out of sequence, which for a few LAN
	based protocols is a great source of upset.


	Beowulf systems have "bonding" in use for parallel Ethernet
	links in between two machines, however THAT is not EtherChannel
	compatible thing!

Maybe we should adopt's sun naming then, and call it 'Trunking'.

This is the same driver that Beowulf uses, and it is Etherchannel
compatible.

The only part of Etherchannel we don't support is the XOR channel
selection (yuck!) and the automatic configuration of the links (it's a 
MII thing, that's undocumented.)

Leave it as Ethernet Bonding.

I do think the new code is much better. Anyone who is considering using trunking
for their projects should use the new code since it has link monitoring and
active backup mode. However, I am a maniac when it comes to kernel testing. If I
say it really works, it usually works. This code has been tested much and bugs
were fixed. However, it has not been tested enough that I may bet by head on
saying there are no known issues. This is because I did not have access to all
hardware that was needed to complete the tests in time.

The code is not worse than the old code. However, a clear note must be made that
this is experimental code and probably has small issues. So if it is included,
it must me marked as experimental.
