The latest revision of the labeled policy patches which enable both labeled
and unlabeled policy support for NetLabel. This revision takes into account
Chris' feedback from the first version and reduces the number of interface
calls in each domain down to two at present: one for unlabeled access, one for
NetLabel access. The older, transport layer specific interfaces, are still
present for use by third-party modules but are not used in the default policy
modules.
trunk: Use netmsg initial SID for MLS-only Netlabel packets, from Paul Moore.
This patch changes the policy to use the netmsg initial SID as the "base"
SID/context for NetLabel packets which only have MLS security attributes.
Currently we use the unlabeled initial SID which makes it very difficult to
distinquish between actual unlabeled packets and those packets which have MLS
security attributes.
sudo should be able to getattr on all executables not just
bin_t/sbin_t. Confined executeables run from sudo need this.
sudo_exec_t needs to be marked as exec_type so prelink will work correctly.
sudo semanage should work
- Allow semanage to read from /root on strict non-MLS for
local policy modules.
- Gentoo init script fixes for udev.
- Allow udev to read kernel modules.inputmap.
- Dnsmasq fixes from testing.
- Allow kernel NFS server to getattr filesystems so df can work
on clients.

Attached is a patch which I've tested against selinux-policy-2.4.2-1
that implements this additional constraint. The name is still a bit
forced, but it works.
