- see if we can drop more message validation on the sending side
- add API to clone sd_bus_message objects
- systemd-bus-proxyd needs to enforce good old XML policy
- - upload minimal kdbus policy into the kernel at boot
- kdbus: matches against source or destination pids for an "strace -p"-like feel. Problem: The PID info needs to be available in userspace too...
- longer term: priority inheritance
- check sender of response messages
- port to sd-resolve for connecting to TCP dbus servers
- constructors for bus messages should probably not be OK with a NULL bus pointer
- .busname units should not use get_user_creds()/get_cgroup_creds() but instead do NSS only in temporarily forked off child
- - .busname units need settings for controlling the attached creds, and timestamps for messages queued into its names.
* sd-event
- allow multiple signal handlers per signal?
