    Pull security layer updates from James Morris:
    
     - a major update for AppArmor. From JJ:
    
         * several bug fixes and cleanups
    
         * the patch to add symlink support to securityfs that was floated
           on the list earlier and the apparmorfs changes that make use of
           securityfs symlinks
    
         * it introduces the domain labeling base code that Ubuntu has been
           carrying for several years, with several cleanups applied. And it
           converts the current mediation over to using the domain labeling
           base, which brings domain stacking support with it. This finally
           will bring the base upstream code in line with Ubuntu and provide
           a base to upstream the new feature work that Ubuntu carries.
    
         * This does _not_ contain any of the newer apparmor mediation
           features/controls (mount, signals, network, keys, ...) that
           Ubuntu is currently carrying, all of which will be RFC'd on top
           of this.
    
     - Notable also is the Infiniband work in SELinux, and the new file:map
       permission. From Paul:
    
          "While we're down to 21 patches for v4.13 (it was 31 for v4.12),
           the diffstat jumps up tremendously with over 2k of line changes.
    
           Almost all of these changes are the SELinux/IB work done by
           Daniel Jurgens; some other noteworthy changes include a NFS v4.2
           labeling fix, a new file:map permission, and reporting of policy
           capabilities on policy load"
    
       There's also now genfscon labeling support for tracefs, which was
       lost in v4.1 with the separation from debugfs.
    
     - Smack incorporates a safer socket check in file_receive, and adds a
       cap_capable call in privilege check.
    
     - TPM as usual has a bunch of fixes and enhancements.
    
     - Multiple calls to security_add_hooks() can now be made for the same
       LSM, to allow LSMs to have hook declarations across multiple files.
    
     - IMA now supports different "ima_appraise=" modes (eg. log, fix) from
       the boot command line.
