      selinux: Support for the new TUN LSM hooks · ed6d76e4
      Paul Moore authored
      Add support for the new TUN LSM hooks: security_tun_dev_create(),
      security_tun_dev_post_create() and security_tun_dev_attach().  This includes
      the addition of a new object class, tun_socket, which represents the socks
      associated with TUN devices.  The _tun_dev_create() and _tun_dev_post_create()
      hooks are fairly similar to the standard socket functions but _tun_dev_attach()
      is a bit special.  The _tun_dev_attach() is unique because it involves a
      domain attaching to an existing TUN device and its associated tun_socket
      object, an operation which does not exist with standard sockets and most
      closely resembles a relabel operation.

      lsm: Add hooks to the TUN driver · 2b980dbd
      Paul Moore authored
      The TUN driver lacks any LSM hooks which makes it difficult for LSM modules,
      such as SELinux, to enforce access controls on network traffic generated by
      TUN users; this is particularly problematic for virtualization apps such as
      QEMU and KVM.  This patch adds three new LSM hooks designed to control the
      creation and attachment of TUN devices, the hooks are:
      
       * security_tun_dev_create()
         Provides access control for the creation of new TUN devices
      
       * security_tun_dev_post_create()
         Provides the ability to create the necessary socket LSM state for newly
         created TUN devices
      
       * security_tun_dev_attach()
         Provides access control for attaching to existing, persistent TUN devices
         and the ability to update the TUN device's socket LSM state as necessary
