2.6.12-rc6-mm1 patches testing

I noticed a new set of patches were out, so I gave it usual bashing. Maybe this will be useful to someone else:
1) as before fp-state does not apply.
2) os-main gave me a reject on arch/um/kernel/main.c fixed by simply removing the file.

Built ok (no tweaks needed this time!).
Runs ok, but it is still loosing memory fast.

Then I tried adding some more experimental features... Attached is a stacktrace I encountered (pcap related):
Seems like the pcap patch is causing some problems when running in a chroot which does not have the libraries required by pcap (nss?) Some processes were still running when I got back to the shell. Btw, how do I figure out which libs I need to copy to the chroot?

But apart from that slight problem, when running outside the chroot it works exactly as expected. I vote for including it in the next release with appropriate warnings about runtime libraries issues. Now, if someone could have a look at hppfs I could resurect my honeypots.

Also, is anyone interested in some SELinux policies for UML? They need a little bit of tidying up but seem to work. See below (I extracted the generic part - unfortunately some parts are specific to my setup).

It happens only when inside the chroot, right?

? You applied it on your own, or have I merged it somewhere without noticing? See my signature about that.

Yes, it's related to the compilation-time warning somebody (either you or Nix) got...

Well, it was segfaulting on exit, so it's a bit normal. Well, it shouldn't segfault in that case but simply handle the error gracefully.

Hmm, look at /etc/nsswitch.conf (to copy inside) and /lib/libnss_* (to copy too, you can limit what you copy by looking at the configuration).

I've not the time, however test the attached patches. The first one fixes the basical bugs; the second one could be needed to fix a fd leak... but I don't think it's needed at all, so test with only the first and let me know if the 2nd is needed, or if there are any problems (in that case, a ready-to-use hppfs configuration + explaination would be happily accepted, I've really little time now).

I had marked it as CONFIG_BROKEN because it was giving some bad compilation warnings, which showed its almost non-existant usage (because those warnings showed that it would not work *absolutely*).

Actually I'm now seeing that they were caused by this patch:

http://linux.bkbits.net:8080/linux-2.5/cset%40412b86aaOElFX7HLh6UrLu-E1hQJSA?nav=index.html|
src/.|src/fs|src/fs/hppfs|related/fs/hppfs/hppfs_kern.c

which forgots some cleanups... so I guess it worked before and will work with this mini-patch.

SPLIT include/linux/autoconf.h -> include/config/*
CC fs/hppfs/hppfs_kern.o

I guess yes, it would be very useful.... but against which distro policy are they prepared? Fedora, I guess, correct?

IIRC, in fact, policies "link" together, for instance your one below refers to tmp_t...

Also, I guess this policy needs some security label settings on files, right?

Would you put it on the Wiki, please? Thanks

Wow! Is this the "assembler-like language" that lwn.net mentioned?

This should be restricted somewhere to UML root_fs's, right (or maybe that is done with Security labels...)?

"tmpfile" is already assigned to files in /tmp...

Allow execution of temporary files? Guess this is needed to avoid /tmp being like noexec, but does this allow to exec a random process on the host being put inside tmp?

Don't think it's needed...
We also delete hppfs_delete_inode since it just implements the default behaviour.

Yes.

I applied it separately.

Yep, I saw them.

Thanks, I'll try that.

Will do.

(..)

They are designed on gentoo but should work on most selinux systems.

All policies are based on the core policies, all of them have tmp_t, bin_t, etc_t, usr_t, var_t and much more.

Yep, that part is much more specific to my setup: the place where you install the UML instances is not part of the LSB, so I didn't include the file labels in the previous email. What is the consensus on where UML should be installed on a production system? (assuming multiple instances + possibility of a chroot)

Will do.

Not sure what you mean.

Yes, something like:
/chroot/uml/1/root_fs -- system_u:object_r:um_fs_t

That's because my um_tmp_t is not in /tmp (it is in chroot somewhere else)

AFAIK, it would allow a file with this label to be executed. I was hoping that allowing just the directory to be "execute"-able would be enough but it is not. Is this due to the uml tmp-exec check? How is it done?

Forgot to add a smilie to mark the pun ;-) (Always remind me of my errors.....)

Ok, good thing.

There is no consensus, so that should be parametrized somehow (if policies don't have a builtin preprocessor, then sed is a good last resort - put the parameters inside %%, like %UML_ROOT_FS_PATH%, and use sed on that to produce the policy).

lwn.net said that writing a SELinux policy was a terrible and complicate task...

Sorry, this was a question....

This label is auto-given by some of the above file_type_auto_trans(um_t, tmp_t, um_tmp_t)
or something like that, right? Is a normal user restricted from assigning this label another way or anybody can give this label and cross the check?

UML needs simply to mmap (PROT_EXEC) datas from the /tmp/vm_XXXXXX file to work, and so it tries doing this very early, to give the user a hint on what happens. On a fs mounted noexec this is forbidden, so possibly it's forbidden also by SELinux; however, it would be nicer if SELinux could simply allow mmap()ing with PROT_EXEC without allowing file execution...; allowing mmap() does not put a big hole inside protections while allowing file execution does...means that if the user can supply a program to execute, that program can be written to mmap() and execute code from /tmp, but at that point the intruder could simply execute his code.

[OT: Mostly SELinux discussion]

It allows basic regular expressions with '.','*','?','+' and grouping '()'.
I'm not too keen on sed because this would prevent the policy from being merged upstream.
Maybe now is a good time to choose a directory by default and users who deviate can use softlinks or tweak their policy.

Indeed, the learning curve is quite steep.
From what I remember of assembly language (1980s), it is on par. It uses lots of macros to try to simplify configuration, I'm not sure it really helps. It is hard to work them backwards.

exactly! see it isn't that hard! (that's one of the macros) Anyone in the um_t domain creating files in tmp_t will have these files automatically labelled as um_tmp_t.

No user can assign a label unless explicitly given the access rights (least-privilege principle)

This one's beyond me! I can just about read selinux policies...but not selinux internals.
I'll write another email for the selinux ML.

Updated the title too.

Hmm, so there is a central repository of policies...

Hmm, well, who uses SELinux will have to setup things anyway, so they can even move their files around. Assuming there will be a chroot too, using /chroot (which is mandated by Who Knows Who, but is used on Gentoo for the dhcp daemon) or better /chroot/uml would be good.

However, would a chroot work with SELinux or do you need to put the "chrooting" also in the policy?

Btw, I really need to allow UML to chroot on its own, btw... and options for changing UID/GID after setup...
From what I remember of assembly language (1980s), it is on par.

Well, I'm good at guessing about unknown languages...

Good.

Sadly, by looking at the code, it seems that this is not possible... execution controls are implemented through mmap() controls.

Well, I tried to define generic policies for my chrooted services when I migrated them to selinux, but there are issues.
I'm looking into it.

That would be very nice.

I'll keep you posted as I learn more about SELinux and how to make UML run smoothly in a chrooted/selinux environment.

Possibly the UML folks could elaborate on what UML is trying to do here? In the long term, I'd advise changing its behavior if possible, as allowing execution of arbitrary code is obviously undesirable and use of /tmp will break noexec /tmp mounts as noted above regardless of what SELinux does.

In the short term, you naturally have the option of adding:

	allow um_kernel_t um_tmp_t:file execute;

to your policy as a workaround. This shouldn't actually allow direct execve() of such files, as that would also trigger another check (execute_no_trans if staying in the same domain or entrypoint otherwise), but would allow indirect execution via ld.so (if staying in the same domain).

Yes, I know, we must have a test *against* noexec /tmp, sadly.

However, since UML is a virtual kernel, between its task there is executing programs, in the memory of the virtual guest; this memory is represented by a host file, because it must be shareable by different threads (each of them matches one process/thread executed inside UML; actually there are complications but this is the base idea).

A note: this file is later deleted to avoid it being touched by the host; what I was thinking was if this could be extended to deleting the directory it's in (it could, and this would work); then, maybe the execute permission could be given only to the directory, and the creation of such directories could be restricted to UML (well, given that you make UML put his files not in /tmp but in a reserved place). I.e.:

only the UML "role" (I don't know SELinux so please correct me) can create a folder under /chroot/mem; those folders become of a different role with auto_trans, inside those folders you get execute permission with "allow um_kernel_t um_tmp_t:file execute;", and those folders get deleted as soon as the file has been created, opened and deleted, so only UML can create an mmap'able file; race condition to check here if the attacker creates a file while the directory exists but not difficult to solve; I guess this is possible with SELinux.

Obviously this requires a bit of hacking to the UML kernel, but is possible; the right question is if this is requested.

Yes, Antoine did something such but he was searching a better solution.

Good...

I don't understand the domain concept... however, by "indirect execution" you mean simply running /lib/ld.so <fileName>, don't you? In this case, since the kernel must just mmap() ld.so and not execve() it, couldn't we deny execve("/lib/ld-linux.so") via the checks you mentioned above?

Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".

Shared anon mapping?

It is already the case that a separate type (um_tmp_t) is being applied to the file, and I presume that the policy only allows um_kernel_t to create/modify files with this type, so policy should ensure that no other process can touch the file and that no other process can trick uml into using a different file (because um_kernel_t will lack execute permission to any other xxx_tmp_t type, and thus the mmap would fail).

Moving from /tmp to a dedicated location with its own type or using a shared anon mapping would make it clear that we are dealing with something other than a normal /tmp file, as well as fixing the noexec /tmp problem. As far as an attacker creating a file, policy should prevent them from being able to create a file in the necessary type to allow execution, so that shouldn't be a problem. Naturally, if uml itself is subverted, it may be induced to execute arbitrary code from the memory.

Yes, execute_no_trans would also apply there.

Small correction: local file override works fine (files in the host's fake proc appear in the guest's /proc) but I can't get the honeypot.pl script to interact with it.

That is allowed, too? The daemon uses normal files only to forcibly "remove" entries, while it uses sockets for the rest.

Ok, let's see... that script supplies the needed values and uses the libraries in separate perl modules...

This is based on the one from the uml_utilities tarball.

Have you tested that his libraries are found / that the script works with a 2.4 UML, first?

Also, have you tested if it's the chroot and/or SELinux interacting? The daemon communicates through a Unix domain socket when host contents are supplied ... the base path is $ARGV[0], i.e. the first parameter...

Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".

AFAIK That has always been the case. I was using it to hardcode the cpuinfo and cmdline shown in honeypots.

Yep, I was running this instance outside of the chroot for now (because of the libcap lib dependency) and not where the honeypot.pl expected it. Also, the path was wrong chroot/proc/proc, 'lsof' showed me what I was doing wrong, but it still isn't working as expected - more on this later.

BTW, I copied /lib/libnss* to the chroot but the pcap interface does not come up:
ifconfig eth1 0.0.0.0 promisc up
SIOCSIFFLAGS: No such device
SIOCSIFFLAGS: No such device
So something else must be missing... Any ideas?

Try also /lib/libresolv.so.2...

In general, post what appears on dmesg (if anything appears), then strace / ltrace the UML process to see what's going on, + boot log and command line as normally. Strace could suffice, however...
