In general terms, yes. However there are some specific problems with
this patch, see below.

It's possible to encode this using OStringList. On the other hand
that is complicated and I don't mind if you just drop the excludedir
optional argument, and we'll wait and see if anyone asks for it.

This test shouldn't be 'Always'. It should be conditional on having
selinux.
Do you mean "IfAvailable of HAVE_LIBSELINUX" here?

https://github.com/libguestfs/libguestfs/blob/master/generator/types.ml#L291
However "HAVE_LIBSELINUX" isn't going to work. You need to use the
right option group from this list:

The second if-statement here isn't needed. OString arguments can
never be NULL, *if* the corresponding bitmask bit is set.

New subject: [PATCH V3] NEW API: add a new api restorecon
Dan & Dan,
Any comments on the design of this restorecon interface? As
implemented here, it is merely a simple encoding of the restorecon
command line tool and arguments.
My main worry is that it'll use the wrong policy file, or perhaps no
policy file, or if SELinux isn't enabled properly it'll end up
destroying labels instead of setting them.
Also I've no idea if it's legit to run restorecon on a filesystem from
one guest, using the restorecon command from another system (the host
in this case).
Rich.

The restorecon inside the guest will attempt to read

- From restorecons point of view does this file exists? And is it in the container.
Also restorecon will only work if it thinks SELinux is enabled and the kernel

If you want to fix labels in a guest where the process thinks SELinux is
disabled, then setfiles would be a better tool.

So, Rich, we have some problems here?

BTW It is fairly easy to add C Code to do the labeling here.

Why is that? selabel_file, with setfilecon() or setfscreatecon() should be
able to do what you want?

I mean the API as proposed in the patch, where it just runs
"restorecon" from the host on the guest. There may be other ways to
do it, but none of them seem simpler than the way we currently do it
(touching /.autorelabel in the guest).

Rich.
Yes, as has been stated restorecon will probably not work because it will
either get the wrong labels from the host or think that SELinux is disabled
and do nothing.
/usr/sbin/setfiles PATHTOFILECONTE PATHTORESTORE
Would work on a machine even if it thought SELinux was disabled and you could
specify the path,
Or you could use the c API.
Or you could just trigger a reboot when the system starts up by executing
touch /.autorelabel
