daemon infrastructure. The previous design made it fairly hard to
reload the complex data structures, especially relays and protocols.
One of the reasons was that the privsep'd relayd processes had two
ways of getting their configuration: 1) from memory after forking from
the parent process and 2) and (partially) via imsgs after reload. The
new implementation first forks the privsep'd children before the
parents loads the configuration and sends it via imsgs to them; so it
is only like 2) before. It is based on an approach that I first
implemented for iked(8) and I also fixed many bugs in the code.
Thanks to many testers including dlg@ sthen@ phessler@

for relays. they can be viewed with the new "relayctl show redirects"
command.
(uses the previous change to pf_table.c to get the statistics)
looks good pyr@

(for instance: rename struct service to struct rdr), refer to redirects
otherwise (hoststatectl output).

what the daemon does - it is a relayer that pays attention to the status
of pools of hosts; not a status checkers that happens to do some relaying

Especially useful when interval is rather long.
I was supposed to commit this before 4.2.

loadbalancing, SSL acceleration, general-purpose TCP relaying, and
transparent proxying.
see hoststated.conf(5) and my upcoming article on undeadly.org for

- minor change of the "hostatectl show" command output
- increase the max service and tag names (max pf tag name size is 64 now!)
thanks to pyr who found a bug in my initial diff

remote hosts and dynamically alter pf(4) tables and redirection rules
for active server load balancing. The daemon has been written by
Pierre-Yves Ritschard (pyr at spootnik.org) and was formerly known as
"slbd".
The daemon is fully functional but it still needs some work and
cleanup so we don't link it to the build yet. Some TODOs are a
partial rewrite of the check_* routines (use libevent whenever we
can), improvement of the manpages, and general knf and cleanup.
