2016-01-03	forgot to call RB_INIT. but yet things mostly worked...	Ted Unangst

2015-12-17	add return code to newrequest to distinguish between cache hit and error.	Ted Unangst
	we want to keep looping for more requests after a hit, not stop. (though i'm reconsidering if the looping is worthwhile. maybe should just return to kevent() after each request.)
2015-12-12	correct comment	Ted Unangst

2015-12-11	it's not necessary to use a tree to track requests if kevent can do this.	Ted Unangst

2015-12-08	more better fake replies. servfail is the correct response.	Ted Unangst

2015-12-05	all the signal ignoring can be done in one place	Ted Unangst

2015-12-05	pull the config file opening up considerably earlier to fail fast.	Ted Unangst
	parsing is still done in the child, so we can't guarantee success, but if the file is missing entirely we won't daemonize in that state.
2015-12-04	refine some logging and error messages. errors will now always go to stderr	Ted Unangst
	until daemonized and syslog as well. make logerr() work more like err().
2015-12-04	push daemon call a little later so if the address is in use we see the	Ted Unangst
	error message
2015-12-04	one signal.h should suffice	Ted Unangst

2015-12-04	ignore SIGPIPE. i don't see any way for it to happen, but nevertheless we	Ted Unangst
	definitely don't want to receive it unexpectedly.
2015-12-04	- sync usage	Gleydson Soares
	- add a bit more detail about config alternative file and add -d while here. manpage help from jmc@ schwarze@ thanks a lot! OK tedu jmc schwarze
2015-12-03	when running on a machine without net, rebound will still receive queries	Ted Unangst
	from localhost, but then fail to forward them. this causes the resolver to stall waiting for timeouts in situations where it would otherwise fail quickly. we don't know this happens until it's too late, but we can push the resolver forward by sending back empty replies. ok deraadt
2015-12-02	tell readers about config reloads.	Sebastian Benoit
	ok tedu
2015-12-01	add missing fclose(3)	Gleydson Soares
	ok tedu@
2015-11-27	add getpw to pledge. rpath would normally suffice, but there's some double	Ted Unangst
	checking code in snapshots, and it serves as a useful annotation. from Carlin Bingham
2015-11-24	use canonical pledge argument ordering	Theo de Raadt

2015-11-16	improve logging slightly	Ted Unangst

2015-11-16	the list insertion needs to occur right after we get a valid socket,	Ted Unangst
	as that is the hint that the request is on the list.
2015-11-10	kill the whitespace.. kill the whitespace..	Theo de Raadt

2015-11-01	chroot to pw_dir instead of the hard-coded /var/empty. Also make the	Reyk Floeter
	chroot+chdir step look more like in the other privsep daemons. OK tedu@
2015-10-30	it is necessary to call tzset() to get syslog timestamps correct.	Ted Unangst
	i am quite surprised by this, but it's the way things are, so do it. reported by naddy
2015-10-29	put timeout nullification in correct spot	Ted Unangst

2015-10-29	be a little more precise about checking filters	Ted Unangst

2015-10-29	refold a few lines	Ted Unangst

2015-10-29	collect some cool stats and print them out with SIGUSR1	Ted Unangst

2015-10-28	impose some limit on the cache size as well.	Ted Unangst

2015-10-28	if accept() fails due to fd exhaustion, stop accepting for one second.	Ted Unangst
	should only happen for ENFILE, but check for EMFILE too.
2015-10-28	bug in the request tree code: requests were being added to the tree before	Ted Unangst
	the socket (the key) was being set. move the enqueue code later, and fix freerequest to only dequeue if socket is set.
2015-10-28	twiddle with rlimit to give us a few more files. use rlimit as a hint as	Ted Unangst
	to how many requests to allow open at once. start closing old ones as we approach the limit, which means we track the number of outstanding requests (and count tcp as two). also rename tcp "phase" to tcp, and use it as a more direct indicator.
2015-10-28	add pledge to main process, though it needs a few more options	Ted Unangst

2015-10-28	use an rb tree for the cache too. modelled after the reqtree.	Ted Unangst

2015-10-28	use an rb tree for finding requests. from Dimitris Papastamos	Ted Unangst

2015-10-26	one second amnesty for timeouts so we don't spin with short timeouts	Ted Unangst

2015-10-26	set listening sockets to nonblocking, then handle as many incoming requests	Ted Unangst
	as we can in the loop instead of keventing per request.
2015-10-17	don't need fcntl for non blocking socket, just ask for it upfront	Ted Unangst

2015-10-16	save some file descriptors. instead of a pipe, use kevent to watch parent	Ted Unangst

2015-10-16	naddy would like the child to exit when the parent dies.	Ted Unangst
	hook up a pipe between them and watch for eof in the child.
2015-10-16	life is simpler if all requests go in the fifo, and then just remove them	Ted Unangst
	in the error case instead of duplicating code.
2015-10-16	deraadt tells me i'm supposed to check if connect() actually worked.	Ted Unangst

2015-10-16	two phase handling for tcp so that slow connects don't stall the process	Ted Unangst

2015-10-16	save request length in cache. naddy noticed we weren't getting any hits.	Ted Unangst

2015-10-16	fine tune the logging some more	Ted Unangst

2015-10-16	simplify logging functions. once a daemon, always a daemon	Ted Unangst

2015-10-16	safety check that we're dealing with the filter we expect	Ted Unangst

2015-10-16	most things should be static	Ted Unangst

2015-10-16	exit(1) is better for the impossible condition	Ted Unangst

2015-10-15	it is perhaps better style to not call close() on -1, even if harmless	Ted Unangst

2015-10-15	make sure req is zeroed in tcp case	Ted Unangst

2015-10-15	better memory handling of the request/cache chain	Ted Unangst
