  "message": "bgpd: RFC 5082 Generalized TTL Security Mechanism support\n\n* bgpd: Add support for RFC 5082 GTSM, which allows the TTL field to be used\n  to verify that incoming packets have been sent from neighbours no more\n  than X IP hops away. In other words, this allows packets that were sent from\n  further away (i.e. not by the neighbour with known distance, and so possibly\n  a miscreant) to be filtered out.\n* lib/sockunion.{c,h}: (sockopt_minttl) new function, to set a minimum TTL\n  using the IP_MINTTL socket opt.\n* bgpd.h: (BGP_ERR_NO_EBGP_MULTIHOP_WITH_TTLHACK) define for command\n  error for minttl.\n  (struct peer) add a config variable, to store the configured minttl.\n  (peer_ttl_security_hops_{set,unset}) configuration handlers\n* bgpd.c: (peer_group_get) init gtsm_hops\n  (peer_ebgp_multihop_{un,}set) check for conflicts with GTSM. Multihop and\n  GTSM can\u0027t both be active for a peer at the same time.\n  (peer_ttl_security_hops_set) set minttl, taking care to avoid conflicts with\n  ebgp_multihop.\n  (bgp_config_write_peer) write out minttl as \"neighbor .. ttl-security hops X\".\n* bgp_vty.c: (bgp_vty_return) message for\n  BGP_ERR_NO_EBGP_MULTIHOP_WITH_TTLHACK\n  (peer_ebgp_multihop_{un,}set_vty)\n* bgp_network.c: (bgp_accept) set minttl on accepted sockets if appropriate.\n  (bgp_connect) ditto for outbound.\n",
