I'm not sure. If this is a problem then skip the Postfix bit and merge the rest, I can investigate Postfix more later.
I've merged this, though I'd still prefer to hear more about the Postfix change, if possible.

Also has some dbus policy which probably isn't strictly a systemd thing, but it all came at the same time.Is all the postfix dbus usage due to a postfix change or something else? I want to look for a pattern if this is not due to postfix code changes. I don't think I have any issues with anything else in the patch, but will wait for the above answer to try to merge in one shot.Index: refpolicy-2.20180701/policy/modules/admin/logrotate.te =================================================================== --- refpolicy-2.20180701.orig/policy/modules/admin/logrotate.te +++ refpolicy-2.20180701/policy/modules/admin/logrotate.te @@ -38,6 +38,8 @@ role system_r types logrotate_mail_t; #allow logrotate_t self:capability { chown dac_override dac_read_searchfowner fsetid kill setgid setuid sys_nice sys_resource };> +# systemctl asks for net_admin +dontaudit logrotate_t self:capability net_admin; allow logrotate_t self:process { transition signal_perms getsched setsched getsession getpgid setpgid getcap setcap share getattr setfscreate noatsecure siginh setrlimit rlimitinh dyntransition setkeycreate setsockcreate getrlimit }; allow logrotate_t self:fd use; allow logrotate_t self:key manage_key_perms; Index: refpolicy-2.20180701/policy/modules/services/cron.te =================================================================== --- refpolicy-2.20180701.orig/policy/modules/services/cron.te +++ refpolicy-2.20180701/policy/modules/services/cron.te @@ -378,6 +378,10 @@ optional_policy(` ') optional_policy(` + init_dbus_chat(crond_t) + ') + + optional_policy(` unconfined_dbus_send(crond_t) ')')Index: refpolicy-2.20180701/policy/modules/services/networkmanager.te =================================================================== --- refpolicy-2.20180701.orig/policy/modules/services/networkmanager.te +++ refpolicy-2.20180701/policy/modules/services/networkmanager.te @@ -138,6 +138,8 @@ dev_rw_wireless(NetworkManager_t) domain_use_interactive_fds(NetworkManager_t) domain_read_all_domains_state(NetworkManager_t) +# /etc/resolv.conf is a symlink written by NM +files_manage_etc_symlinks(NetworkManager_t) files_read_etc_runtime_files(NetworkManager_t) files_read_usr_files(NetworkManager_t) files_read_usr_src_files(NetworkManager_t) @@ -346,6 +348,7 @@ optional_policy(` ')optional_policy(`+ systemd_read_logind_pids(NetworkManager_t) systemd_read_logind_sessions_files(NetworkManager_t) systemd_write_inherited_logind_inhibit_pipes(NetworkManager_t)')Index: refpolicy-2.20180701/policy/modules/services/ntp.fc =================================================================== --- refpolicy-2.20180701.orig/policy/modules/services/ntp.fc +++ refpolicy-2.20180701/policy/modules/services/ntp.fc @@ -13,6 +13,7 @@ /etc/rc\.d/init\.d/ntpd? -- gen_context(system_u:object_r:ntpd_initrc_exec_t,s0)/run/ntpd\.pid -- gen_context(system_u:object_r:ntpd_pid_t,s0)+/run/systemd/timesync(/.*)?gen_context(system_u:object_r:ntpd_pid_t,s0) /usr/bin/ntpd --gen_context(system_u:object_r:ntpd_exec_t,s0)/usr/bin/ntpdate --gen_context(system_u:object_r:ntpdate_exec_t,s0)@@ -31,6 +32,7 @@ /var/lib/ntp(/.*)?gen_context(system_u:object_r:ntp_drift_t,s0)/var/lib/sntp-kod(/.*)?gen_context(system_u:object_r:ntp_drift_t,s0)/var/lib/systemd/clock --gen_context(system_u:object_r:ntp_drift_t,s0) +/var/lib/private/systemd/timesync(/.*)? -- gen_context(system_u:object_r:ntp_drift_t,s0)> /var/lock/ntpdate -- gen_context(system_u:object_r:ntpd_lock_t,s0)> Index: refpolicy-2.20180701/policy/modules/services/openvpn.te =================================================================== --- refpolicy-2.20180701.orig/policy/modules/services/openvpn.te +++ refpolicy-2.20180701/policy/modules/services/openvpn.te @@ -175,3 +175,7 @@ optional_policy(` networkmanager_dbus_chat(openvpn_t) ')')+ +optional_policy(` + systemd_use_passwd_agent(openvpn_t) +') Index: refpolicy-2.20180701/policy/modules/services/postfix.te =================================================================== --- refpolicy-2.20180701.orig/policy/modules/services/postfix.te +++ refpolicy-2.20180701/policy/modules/services/postfix.te @@ -347,6 +347,12 @@ optional_policy(` ')optional_policy(`+ dbus_send_system_bus(postfix_master_t) + dbus_system_bus_client(postfix_master_t) + init_dbus_chat(postfix_master_t) +') + +optional_policy(` sendmail_signal(postfix_master_t)')@@ -376,6 +382,10 @@ optional_policy(` init_dbus_chat(postfix_bounce_t)')+optional_policy(` + dbus_system_bus_client(postfix_bounce_t) +') + ######################################## #
