[meta-selinux][PATCH 0/3] refpolicy virtual package

[Philip Tricca]

We currently require each image to depend on the policy (or multiple
policies) that they want installed and the selinux-config package
enables the DEFAULT_POLICY. Since only one policy can be in effect at a
time, and we're targeting "embedded" systems it makes sense (to me at
least) that we would treat the policy much like we do the kernel and use
a virtual provider.

Feedback would be much appreciated,
Philip

  Integrate selinux-config into refpolicy_common.

[meta-selinux][PATCH 1/3] refpolicy: Setup virtual/refpolicy provider.

[Philip Tricca]

This allows us to provide a default policy through the
PREFERRED_PROVIDER mechanism for each of the example distro configs.
Consumers of meta-selinux will be able to override this at the config
level instead of having to depend on a specific policy package. We do
lose the ability install more than one policy package but this falls
in line with the embedded nature of the project.

[meta-selinux][PATCH 2/3] Integrate selinux-config into refpolicy_common.

[Philip Tricca]

With the virutal package there's no need for a separate recipe to build
the config. This can be generated and included as part of the policy
package.

[meta-selinux][PATCH 3/3] refpolicy_common: Sanity test DEFAULT_ENFORCING value and set default.

[Philip Tricca]

Use the anonymous python function to be sure the value set for
'SELINUX' in the config file is something useful. In the event that
DEFAULT_ENFORCING isn't set to one of the 3 permissible values we
set it to 'permissive'.

I've tried this out today and it all looks good to me, I've tried
breaking the sanity check on DEFAULT_ENFORCING as we discussed and it
still seems to do the right thing.  Since this is what we were
discussing last week and it seemed to make sense at the time, I went
ahead and merged your patches for you.

Philip,

Can you consider to withdraw the integration?

I think this was always the intent with the series Philip submitted last
week (for reference, the thread is
https://www.mail-archive.com/yocto@yoctoproject.org/msg28530.html).
Isn't this (part of) the expected behaviour of the virtual provider
mechanism?  We did discuss what it would mean to be trying out multiple
policies on a system at the same time and at the time it seemed like the
"just works" angle was more important than "buffet style" when it came
to providing policy on the image.

It might be worth considering extending the changes to only do some
install steps at, say, do_rootfs but I don't know if that even makes
sense, this is really the first I've thought of it.  I think Philip's
original changes are good, though, for our maintenance and for clients
of meta-selinux.

This is the question I think we need to figure out. My understanding
(quite possibly wrong) is that the virtual provider stuff would prevent
the installation of more than one provider. I hadn't considered the
implications for the sysroot.

Is the ability to install multiple providers in the sysroot expected? I
imagine that this problem must have been solved before in another
package with virtual providers that install the same file. I'm happy to
doing some digging here but if anyone knows of a good example I'd
appreciate a pointer.

I guess the thing I like the most about setting the policy package up as
a virtual package is the ability to select the policy type as a distro
config. The virtual provider seemed like a natural fit as it's a pattern
that similar packages (kernel etc) use extensively.

There may be a middle ground and I think that would be leaving the
configuration file as a separate package. Personally I liked the idea of
rolling the config file into the policy package as it was always a bit
awkward requiring coordination of some variables across the policy and
the config package which made it a bit brittle.

Wenzong: A few questions: What's your use case for building multiple
policy packages? Would you suggest just backing out the removal of the
config package or the whole virtual provider thing?

Thanks,
Philip

Hi Philip,

The virtual provider is OK, just restore the config package is the 
simplest ways for fixing such issue I think.

My use cases include:
a. update refpolicy and build each type to make sure patch/build/install 
work;
b. run world build with meta-selinux layer.

Thanks

That's not necessarily an argument against the change ...

> b. run world build with meta-selinux layer.

... but I think this is.  Or, rather, I think what we have now makes more
sense from an end-user perspective, that your image wouldn't have more
than a single policy installed at a time and that if you tried to install
multiple policies for nearly everyone this represents a mistake and
undesirable behaviour so warnings / errors are appropriate.

But if this is breaking world builds with yocto+meta-selinux, that's
something I'd like to repair.  Though I'm surprised that what we have
right now would break the world builds.  Philip / Wenzong / Mark:  Do you
have publicly-accessible world builds right now?  I don't and I don't have
world builds for yocto+meta-selinux on my autobuilder, but I'll go set one
up if you don't have one.

Oh, it's my fault. I can't reproduce the issue with a fresh build now, 
it must be I had been run refpolicy-* build manually :(

I don't want to install multiple policies to target as well, so I have 
no objection now.

Thanks all for your patience.
