corenetwork.if.in:corenet_sctp_bind_generic_port(),
corenet_dontaudit_sctp_bind_generic_port(), and
corenet_sctp_connect_generic_port()
Removed references to undeclared type ephemeral_port_t.
corenetwork.if.in:corenet_sctp_recvfrom_unlabeled()
Removed references to undeclared type attribute corenet_unlabled_type.
devices.if:dev_read_printk()
Removed references to undeclared type printk_device_t and marked
interface as deprecated because it is now empty.

The type user_devpts_t is actually declared in userdomain.te and moving it
removes a dependency of the base module (which terminal is a part) on a
module.
Moved the file contexts to label slave pseudo terminals with the
user_devpts_t type from terminal.fc to userdomain.fc.

The type initrc_var_run_t is actually declared in init.te and moving it
removes a dependency of the base module (which files is a part) on a
module.
Moved the file contexts to label motd for debian systems with the
initrc_var_run_t type from files.fc to init.fc.

Deprecate mmap_file_perms and mmap_files_pattern since they are not fully
informative about their access. Replace with a full set of permission
set macros for mmap.
Requested for selinux-testsuite usage.
NVMe has several dev nodes for each device:
/dev/nvme0 is a char device for communicating with the controller
/dev/nvme0n1 is the block device that stores the data.
/dev/nvme0n1p1 is the first partition
This patch properly completes the implementation of the MLS file relabel attributes. In the previous patch [http://oss.tresys.com/pipermail/refpolicy/2016-July/008038.html], a new attribute, mlsfilerelabetoclr, was created. There should have been a second attribute, mlsfilerelabel, created instead of overloading mlsfilewrite for this privilege. I concur with creating new attributes for this situation. I have created the patch below.

The cgroup directory under /sys/fs/cgroup contains a number of
pseudo-filesystems for each cgroup as well as two symbolic links for the
cpu and cpuacct groups, which were legacy symbolic links to the
cpu,cpuacct group.
These rules allow systemd to relabel these symbolic links from tmpfs_t
to their proper context, or otherwise denials will be printed for nearly
all systemd operation involving cgroups.
This change only grants systemd the possibility to relabel the
files. The actual relabelling needs to be done by systemd. The
accompanying change (commit 8739f23) will be released with systemd v236.
I am seeing the following denial (in dmesg) during system startup:
[ 4.623332] type=1400 audit(1507767947.042:3): avc: denied { relabelto } for pid=1 comm="systemd" name="private" dev="tmpfs" ino=5865 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:init_var_run_t:s0 tclass=sock_file
It appears that systemd is attempting to relablel the socket file /run/systemd/private to init_var_run_t but doesn't have permission.
Updated to create new interface for relabeling of sock_files rather than adding to existing interface

Label some shell scripts from bridge-utils correctly. Maybe have ifdef
distro_debian around this, not sure what upstream is doing.
systemd_nspawn_t needs to manage the /etc/localtime symlink if you have a
labeled chroot.
Another dontaudit for mon_local_test_t to stop it spamming the logs.
Support a .d directory for dnsmasq config files.
systemd relabels everything in /dev and /run after loading the policy.
In these directories there is a socket file for udev, /run/udev/control,
which is not allowed to be relabelled from tmpfs_t:
avc: denied { relabelfrom } for pid=1 comm="systemd"
name="control" dev="tmpfs" ino=7027
scontext=system_u:system_r:init_t tcontext=system_u:object_r:tmpfs_t
tclass=sock_file permissive=1
avc: denied { relabelto } for pid=1 comm="systemd" name="control"
dev="tmpfs" ino=7027 scontext=system_u:system_r:init_t
tcontext=system_u:object_r:udev_var_run_t tclass=sock_file
permissive=1
/run/tmpfiles.d directory (used by systemd-tmpfiles service) is also
relabelled.
This is currently denied:
avc: denied { create } for pid=1 comm="systemd" name="pts"
scontext=system_u:system_r:init_t
tcontext=system_u:object_r:devpts_t tclass=dir permissive=1
