Moves netlink neighbour bits to linux/neighbour.h. Also moves bits to be exported to userspace from net/neighbour.h to linux/neighbour.h and removes __KERNEL__ guards, userspace is not supposed to be using it. rtnetlink_rcv_msg() is not longer required to parse attributes for the neighbour layer, remove dependency on obsolete and buggy rta_buf.

When the lookup in a table returns ip6_null_entry the policy routing lookup returns it instead of continuing in the next table, which effectively means it only searches the local table. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

Transforms netlink code to dump link tables to use the new netlink api. Makes rtnl_getlink() available regardless of the availability of the wireless extensions. Adding copy_rtnl_link_stats() avoids the structural dependency of struct rtnl_link_stats on struct net_device_stats and thus avoids troubles later on.

Transforms do_setlink() into rtnl_setlink() using the new netlink api. A warning message printed to the console is added in the event that a change request fails while part of the change request has been comitted already. The ioctl() based nature of net devices makes it almost impossible to move on to atomic netlink operations without obsoleting some of the functionality.

Adds the framework to support multiple IPv6 routing tables. Currently all automatically generated routes are put into the same table.

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.

Add CIPSO/IPv4 and unlabeled packet management to the NetLabel subsystem. The CIPSO/IPv4 changes allow the configuration of CIPSO/IPv4 within the overall NetLabel framework.

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. Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: David S.

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.

Documentation for the NetLabel system, this includes a basic overview of how NetLabel works, how LSM developers can integrate it into their favorite LSM, as well as documentation on the CIPSO related sysctl variables. Also, due to the difficulty of finding expired IETF drafts, I am including the IETF CIPSO draft that is the basis of the NetLabel CIPSO implementation.
