For a long time /root has been treated differently in Red Hat
Distributions then upstream policy.
We do not want to label /root the same as a users homedir. Because of
this we have carried a patch in libsemanage/genhomedircon.c to ignore
/root.
This patch adds a flag to semanage.conf, ignoredirs. That will allow
distributions or users to specify directories that genhomedircon
should ignore when setting up users homedir labeling.

Change the way libsemanage handles disabled modules. In the current
method libsemanage renames the FOO.pp file to FOO.pp.disabled and then
the rebuild process ignores *.disabled modules.
Since we want to start shipping
/etc/selinux/targeted/modules/active/modules/*.pp within the payload of
the rpm. If we continued this method, a policy update would re-enable a
module.
The new mechanism will just create a symbolic link between FOO.pp and
FOO.pp.disabled. Then the library will check all modules, and if a
module has a link, it will not be compiled into the policy. This solves
the rpm update problem. and actually gives us an easier update
capability since if FOO.pp.disabled already exists using the old method,
it will continue to work with the new method.

The attached patch makes the
/etc/selinux/default/contexts/files/file_contexts.homedirs generation process
include the MCS/MLS level.
This means that if you have a user with a MCS/MLS level that isn't SystemLow
then their home directory will be labeled such that they can have read/write
access to it by default.
Unless anyone has any better ideas for how to solve this problem I will upload
this to Debian shortly.
What do the MLS users do in this situation? Just relabel home directories
manually?
Finally it seems that when you run "semanage user -m" the
file_contexts.homedirs doesn't get updated, it's only when you run
"semanage login -m" that it takes affect.

libsemanage produced no errors with the warnings, Im just noticing
big hunks of sections with warning messages:

database_llist.c: In function 'dbase_llist_del':
database_llist.c:278:41: warning: parameter 'handle' set but not used

so add the GCC attribute to quiet these warnings since most go to

I want to change the default of libsemanage to not look for home
directories in getpwent. This patch allows you to set the flag
usepasswd=false in the semanage.conf file. and genhomedircon will only
setup the labeling of /home, /export/home and any confined users homedirs.
If this patch is not acceptable because libsemanage is being rewritten,
I would like the functionality to be added to the new libsemanage.

Looking into this more closely, I believe this is another manifestation
of:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543915#17
which was ultimately traced down to two issues:
1) A missing offset check in libsepol (fixed in libsepol 2.0.38), and
2) A bug / lack of binary mode support in the fmemopen implementation in
glibc that was later fixed, see:
http://sourceware.org/bugzilla/show_bug.cgi?id=6544
Maybe you have the older glibc still?
Looking at the libsemanage code though, I think we could in fact avoid
any dependency on fmemopen by using the native libsepol support for
operating on a memory region via sepol_policy_file_set_mem(), ala:

Each manual page should start with a "NAME" section, which lists the
name and a brief description of the page separated by "\-". These
sections are parsed by "mandb" and stored in a database for the use of
"apropos" and "whatis", so they must be in a certain format. These
manual pages apparently use the wrong format and cannot be parsed by
"mandb". This commit fixes that.

Yes, I'm not sure why you'd need libsemanage during early boot, we
probably should apply this:

This patch adds a function to turn off file contexts validation.
We need this for cross-installs in rpm, where we install policy
into a chroot that has binaries of a different architecture which
cannot be executed on the build system. So, we would like to use
this function to disable executing setfiles. This of course means
the file contexts could be invalid, but we're willing to take
that risk.
