+  o Minor bugfixes (Linux seccomp2 sandbox):
+    - Allow more syscalls when running with "Sandbox 1" enabled:

+    - Allow IPPROTO_UDP datagram sockets when running with "Sandbox 1",

-  o Minor bugfixes (Linux seccomp2 sandbox):

-  o Minor bugfixes (sandboxing):
-    - If we did not find a non-private IPaddress by iterating over
-      interfaces, we would try to get one via
-      get_interface_address6_via_udp_socket_hack().  This opens a
-      datagram socket with IPPROTO_UDP.  Previously all our datagram
-      sockets (via libevent) used IPPROTO_IP, so we did not have that
-      in the sandboxing whitelist.  Add (SOCK_DGRAM, IPPROTO_UDP)
-      sockets to the sandboxing whitelist.  Fixes bug 19660.
