      [IPV6]: Multiple Routing Tables · c71099ac
      Thomas Graf 提交于
      Adds the framework to support multiple IPv6 routing tables.
      Currently all automatically generated routes are put into the
      same table. This could be changed at a later point after
      considering the produced locking overhead.

      [NetLabel]: SELinux support · 7420ed23
      Venkat Yekkirala 提交于
      Add NetLabel support to the SELinux LSM and modify the
      socket_post_create() LSM hook to return an error code.  The most
      significant part of this patch is the addition of NetLabel hooks into
      the following SELinux LSM hooks:
      
       * selinux_file_permission()
       * selinux_socket_sendmsg()
       * selinux_socket_post_create()
       * selinux_socket_sock_rcv_skb()
       * selinux_socket_getpeersec_stream()
       * selinux_socket_getpeersec_dgram()
       * selinux_sock_graft()
       * selinux_inet_conn_request()
      
      The basic reasoning behind this patch is that outgoing packets are
      "NetLabel'd" by labeling their socket and the NetLabel security
      attributes are checked via the additional hook in
      selinux_socket_sock_rcv_skb().  NetLabel itself is only a labeling
      mechanism, similar to filesystem extended attributes, it is up to the
      SELinux enforcement mechanism to perform the actual access checks.
      
      In addition to the changes outlined above this patch also includes
      some changes to the extended bitmap (ebitmap) and multi-level security
      (mls) code to import and export SELinux TE/MLS attributes into and out
      of NetLabel.

      Paul Moore 提交于
      Add a new kernel subsystem, NetLabel, to provide explicit packet
      labeling services (CIPSO, RIPSO, etc.) to LSM developers.  NetLabel is
      designed to work in conjunction with a LSM to intercept and decode
      security labels on incoming network packets as well as ensure that
      outgoing network packets are labeled according to the security
      mechanism employed by the LSM.  The NetLabel subsystem is configured
      through a Generic NETLINK interface described in the header files
      included in this patch.

      [NetLabel]: CIPSOv4 engine · 446fda4f
      Paul Moore 提交于
      Add support for the Commercial IP Security Option (CIPSO) to the IPv4
      network stack.  CIPSO has become a de-facto standard for
      trusted/labeled networking amongst existing Trusted Operating Systems
      such as Trusted Solaris, HP-UX CMW, etc.  This implementation is
      designed to be used with the NetLabel subsystem to provide explicit
      packet labeling to LSM developers.
      
      The CIPSO/IPv4 packet labeling works by the LSM calling a NetLabel API
      function which attaches a CIPSO label (IPv4 option) to a given socket;
      this in turn attaches the CIPSO label to every packet leaving the
      socket without any extra processing on the outbound side.  On the
      inbound side the individual packet's sk_buff is examined through a
      call to a NetLabel API function to determine if a CIPSO/IPv4 label is
      present and if so the security attributes of the CIPSO label are
      returned to the caller of the NetLabel API function.

      [MLSXFRM]: Granular IPSec associations for use in MLS environments · 51bd3986
      Venkat Yekkirala 提交于
      The current approach to labeling Security Associations for SELinux
      purposes uses a one-to-one mapping between xfrm policy rules and
      security associations.
      
      This doesn't address the needs of real world MLS (Multi-level System,
      traditional Bell-LaPadula) environments where a single xfrm policy
      rule (pertaining to a range, classified to secret for example) might
      need to map to multiple Security Associations (one each for
      classified, secret, top secret and all the compartments applicable to
      these security levels).
      
      This patch set addresses the above problem by allowing for the mapping
      of a single xfrm policy rule to multiple security associations, with
      each association used in the security context it is defined for. It
      also includes the security context to be used in IKE negotiation in
      the acquire messages sent to the IKE daemon so that a unique SA can be
      negotiated for each unique security context. A couple of bug fixes are
      also included; checks to make sure the SAs used by a packet match
      policy (security context-wise) on the inbound and also that the bundle
      used for the outbound matches the security context of the flow. This
      patch set also makes the use of the SELinux sid in flow cache lookups
      seemless by including the sid in the flow key itself. Also, open
      requests as well as connection-oriented child sockets are labeled
      automatically to be at the same level as the peer to allow for use of
      appropriately labeled IPSec associations.
      
      Description of changes:
      
      A "sid" member has been added to the flow cache key resulting in the
      sid being available at all needed locations and the flow cache lookups
      automatically using the sid. The flow sid is derived from the socket
      on the outbound and the SAs (unlabeled where an SA was not used) on
      the inbound.
      
      Outbound case:
      1. Find policy for the socket.
      
      2. OLD: Find an SA that matches the policy.
       NEW: Find an SA that matches BOTH the policy and the flow/socket.
         This is necessary since not every SA that matches the policy
         can be used for the flow/socket. Consider policy range Secret-TS,
         and SAs each for Secret and TS. We don't want a TS socket to
         use the Secret SA. Hence the additional check for the SA Vs. flow/socket.
      
      3. NEW: When looking thru bundles for a policy, make sure the
              flow/socket can use the bundle. If a bundle is not found,
              create one, calling for IKE if necessary. If using IKE,
              include the security context in the acquire message to the IKE
              daemon.
      
      Inbound case:
      1. OLD: Find policy for the socket.
       NEW: Find policy for the incoming packet based on the sid of the
            SA(s) it used or the unlabeled sid if no SAs were
            used. (Consider a case where a socket is "authorized" for two
            policies (unclassified-confidential, secret-top_secret). If the
            packet has come in using a secret SA, we really ought to be
            using the latter policy (secret-top_secret).)
      
      2. OLD: BUG: No check to see if the SAs used by the packet agree with
                   the policy sec_ctx-wise.
      
                   (It was indicated in selinux_xfrm_sock_rcv_skb() that
                    this was being accomplished by
                    (x->id.spi == tmpl->id.spi || !tmpl->id.spi) in xfrm_state_ok,
      	      but it turns out tmpl->id.spi
                    would normally be zero (unless xfrm policy rules specify one
                    at the template level, which they usually don't).
       NEW: The socket is checked for access to the SAs used (based on the
            sid of the SAs) in selinux_xfrm_sock_rcv_skb().
      
      Forward case:
       This would be Step 1 from the Inbound case, followed by Steps 2 and 3
      from the Outbound case.
      
      Outstanding items/issues:
      
      - Timewait acknowledgements and such are generated in the
        current/upstream implementation using a NULL socket resulting in the
        any_socket sid (SYSTEM_HIGH) to be used. This problem is not addressed
        by this patch set.
      
      This patch: Add new flask definitions to SELinux
      
      Adds a new avperm "polmatch" to arbitrate flow/state access to a xfrm
      policy rule.
