Semodule stopped using this many years ago. The policy_module() macro will
continue to support an optional second parameter as version.
If it is not specified, a default value of 1 is set.

This usage under /dev/.udev has been unused for a very long time and
replaced by functionality in /run/udev. Since these have separate types,
take this opportunity to revoke these likely unnecessary rules.

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 }

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.
