When SECMARK or Netlabel packet labeling is used, it's useful to
forbid receiving and sending unlabeled packets. If packet labeling is
not active, there's no effect.

Remove unused permission definitions from SELinux.
Many of these were only ever used in pre-mainline
versions of SELinux, prior to Linux 2.6.0. Some of them
were used in the legacy network or compat_net=1 checks
that were disabled by default in Linux 2.6.18 and
fully removed in Linux 2.6.30.
The corresponding classmap declarations were removed from the
mainline kernel in:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=42a9699a9fa179c0054ea3cf5ad3cc67104a6162
Permissions never used in mainline Linux:
file swapon
filesystem transition
tcp_socket { connectto newconn acceptfrom }
node enforce_dest
unix_stream_socket { newconn acceptfrom }
Legacy network checks, removed in 2.6.30:
socket { recv_msg send_msg }
node { tcp_recv tcp_send udp_recv udp_send rawip_recv rawip_send dccp_recv dccp_send }
netif { tcp_recv tcp_send udp_recv udp_send rawip_recv rawip_send dccp_recv dccp_send }

My previous version had a minor bug in admin_role where it was using cobblerd_var_log_t, and cobblerd_var_lib_t instead of cobbler_var_log_t, and cobbler_var_lib_t.
Whilst i was at it, i decided the implement a cobbler_etc_t for cobbler content in /etc. This because you cannot admin a cobbler environment witouth having access to cobbler config files and i dont want to give cobbler_admin access to manage etc_t.
As a consequence if this i also removed the files_read_etc_files(cobblerd_t), as i think that cobbler only needed it to read its own files in /etc. However this is not confirmed, and it may need read access to etc_t afteral.
Also i would like to underscore my reason for using public_content_rw_t. One of the reasons is that i do not want to give cobbler access to manage httpd_sys_content_rw_t. In general i do not want to depend on apache module at all.

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.
