systemd creates a new network namespace for services which are using
PrivateNetwork=yes.
In the implementation, systemd uses a socketpair as a storage buffer for
the namespace reference file descriptor (c.f.
https://github.com/systemd/systemd/blob/v228/src/core/namespace.c#L660).
One end of this socketpair is locked (hence the need of "lock" access to
self:unix_dgram_socket for init_t) while systemd opens
/proc/self/ns/net, which lives in nsfs.
While at it, add filesystem_type attribute to nsfs_t.
Even if there is not FHS provision for this, systemd is using
/dev/hugepages to mount the hugetlbfs fs by default.
The needed file contexts are already present
Associate the new xattrfs attribute to fs_t and the pseudo filesystems
that we know support xattr
This patch adds the attribute to the following (pseudo) filesystems
- device_t
- devpts_t
- fs_t
- hugetlbfs
- sysfs_t
- tmpfs_t
Generic interface to platform dependent persistent storage
https://www.kernel.org/doc/Documentation/ABI/testing/pstore
This basically works pretty much the same as cgroup file systems from a
SELinux perspective
Make sure that the installed /sys/fs/pstore directory is labeled
properly so that the pstore file system can be mounted on that
I also removed the files_type() calls as they are duplicate (it is
already called in files_mountpoint)

Move devtmpfs to devices module (remove from filesystem module)
Make device_t a filesystem
Add interface for associating types with device_t filesystem (dev_associate)
Call dev_associate from dev_filetrans
Allow all device nodes associate with device_t filesystem
Remove dev_tmpfs_filetrans_dev from kernel_t
Remove fs_associate_tmpfs(initctl_t) - redundant, it was in dev_filetrans, now in dev_associate
Mounton interface, to allow the kernel to mounton device_t
