Stubby is a DNS resolver that encrypts DNS queries and transmits them to a resolver in a TLS channel. It therefore requires less permissions than a traditionnal DNS resolver such as named or unbound (provided by module "bind"). cf. https://dnsprivacy.org/wiki/display/DP/DNS+Privacy+Daemon+-+Stubby This program is packaged for Arch Linux, Debian, etc. DNS-over-TLS uses TCP port 853, which does not seem to conflict with existing ports. Label it like other DNS ports. init_dbus_chat(stubby_t) is required on systemd-based distributions because stubby's service uses DynamicUser=yes [1]. Without this statement, the following denials are reported by dbus: type=USER_AVC msg=audit(1550007165.936:257): pid=274 uid=81 auid=4294967295 ses=4294967295 subj=system_u:system_r:system_dbusd_t msg='avc: denied { send_msg } for msgtype=method_call interface=org.freedesktop.DBus member=Hello dest=org.freedesktop.DBus spid=649 scontext=system_u:system_r:stubby_t tcontext=system_u:system_r:system_dbusd_t tclass=dbus permissive=1 exe="/usr/bin/dbus-daemon" sauid=81 hostname=? addr=? terminal=?' type=USER_AVC msg=audit(1550007165.939:258): pid=274 uid=81 auid=4294967295 ses=4294967295 subj=system_u:system_r:system_dbusd_t msg='avc: denied { send_msg } for msgtype=method_call interface=org.freedesktop.systemd1.Manager member=LookupDynamicUserByUID dest=org.freedesktop.systemd1 spid=649 tpid=1 scontext=system_u:system_r:stubby_t tcontext=system_u:system_r:init_t tclass=dbus permissive=1 exe="/usr/bin/dbus-daemon" sauid=81 hostname=? addr=? terminal=?' type=USER_AVC msg=audit(1550007165.939:259): pid=274 uid=81 auid=4294967295 ses=4294967295 subj=system_u:system_r:system_dbusd_t msg='avc: denied { send_msg } for msgtype=method_return dest=:1.39 spid=1 tpid=649 scontext=system_u:system_r:init_t tcontext=system_u:system_r:stubby_t tclass=dbus permissive=1 exe="/usr/bin/dbus-daemon" sauid=81 hostname=? addr=? terminal=?'
