Here is what we are using. Some of this is because we do a fair amount
of dynamic config in the init scripts, some may be redundant with
other fixes in refpol/F11 because it was originally developed in F9.
policy_module(hack_ipsec,1.0.9)
require { type initrc_t, ipsec_spd_t; attribute domain; }
allow domain ipsec_spd_t:association { polmatch sendto recvfrom };
require { type setkey_t, initrc_tmp_t; }
# autoconfiguration needs this
gen_require(`type ipsec_conf_file_t, ipsec_key_file_t;');
allow initrc_t ipsec_conf_file_t:dir { write remove_name add_name };
allow initrc_t ipsec_conf_file_t:file { rename write setattr
relabelfrom relabelto create unlink };
allow initrc_t ipsec_key_file_t:file { write read rename };
# get setkey to talk to me in enforcing mode
gen_require(`type setkey_t, initrc_devpts_t, initrc_tmp_t;');
allow setkey_t initrc_tmp_t:file { read getattr};
gen_require(`type udev_t, ipsec_conf_file_t;');
allow udev_t ipsec_conf_file_t:file ioctl;
allow udev_t self:key_socket create;
# runtime
gen_require(` type racoon_t, ipsec_spd_t, unlabeled_t; ');
allow unlabeled_t ipsec_spd_t:association polmatch;
allow unlabeled_t self:association sendto;
allow racoon_t unlabeled_t:udp_socket recvfrom;
allow racoon_t unlabeled_t:association setcontext;
mls_socket_read_to_clearance(racoon_t)
mls_socket_write_to_clearance(racoon_t)
corenet_out_generic_if(racoon_t);
corenet_udp_send_generic_node(racoon_t);
