* sd-bus:
- systemd-bus-proxyd needs to enforce good old XML policy
- - kdbus: peeking is subject to a race when we look at a message while the message is being migrated to the implementor's connection. Needs kernel fix, and then we need to invoke the FREE ioctl in busname_peek_message()
- kdbus: maybe add controlling tty and ppid metadata fields
- kdbus: for some reason "busctl monitor" only shows metadata for signal msgs, never method call or method reply msgs
- kdbus: busnames.target should get pulled in by basic.target
cannot pass into sendmsg() of the AF_UNIX sokcet (which only accepts
253 messages)
- kdbus: introduce a concept of "send-only" connections
+ - kdbus: add counter for refused unicast messages that is passed out via the RECV ioctl. SImilar to the counter for dropped multicast messages we already have.
* sd-event
- allow multiple signal handlers per signal?
