2016-09-01naming a union 'sockthing' was a bit silly. sockun will do for now.Ted Unangst
2016-09-01print regular messages to stdout, not errTed Unangst
2016-09-01scan responses for minimum ttl, and cache for min(ttl, 300) instead ofTed Unangst
a fixed amount
2016-08-21introduce a union of sockaddr types and eliminate a lot of casts.Ted Unangst
2016-08-06reset timeout to null when reloopingTed Unangst
2016-07-02check cache tree for collisions when inserting replies.Ted Unangst
if two identical requests are sent out, the first will create a cache entry. the second will not go into the cache tree, but will linger around, causing a crash when we free it and try to remove from the tree. instead, give up if insert fails. diagnosis and initial patch from Duncan.
2016-06-05previous change (r1.27) converted to using non blocking sockets andTed Unangst
spinning on them, trying to preemptively avoid kevent. i've come to conclude this is a poor design. it is exceedingly rare for there to be two requests waiting. instead, we end up burning useless syscalls.
2016-05-31with the kernel perm check fixed, we can do this kevent after setuid,Ted Unangst
but still needs to be before pledge. also check for failure.
2016-05-13fix logging.Ted Unangst
1. va must be restarted before reuse. 2. don't syslog in debug. assume someone is watching stderr.
2016-05-02prepare userland for removing chroot(2) from allowed syscalls under pledge(2).Sebastien Marie
in rebound(8), the worker is still chrooted (and pledged). The supervisor process remains unpledged in order to create workers. ok tedu@
2016-01-03forgot to call RB_INIT. but yet things mostly worked...Ted Unangst
2015-12-17add 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.)
2015-12-12correct commentTed Unangst
2015-12-11it's not necessary to use a tree to track requests if kevent can do this.Ted Unangst
2015-12-08more better fake replies. servfail is the correct response.Ted Unangst
2015-12-05all the signal ignoring can be done in one placeTed Unangst
2015-12-05pull 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.
2015-12-04refine some logging and error messages. errors will now always go to stderrTed Unangst
until daemonized and syslog as well. make logerr() work more like err().
2015-12-04push daemon call a little later so if the address is in use we see theTed Unangst
error message
2015-12-04one signal.h should sufficeTed Unangst
2015-12-04ignore SIGPIPE. i don't see any way for it to happen, but nevertheless weTed Unangst
definitely don't want to receive it unexpectedly.

- 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
2015-12-03when running on a machine without net, rebound will still receive queriesTed 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

2015-11-27add getpw to pledge. rpath would normally suffice, but there's some doubleTed Unangst
checking code in snapshots, and it serves as a useful annotation. from Carlin Bingham
2015-11-24use canonical pledge argument orderingTheo de Raadt
2015-11-16improve logging slightlyTed Unangst
2015-11-16the 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.
2015-11-10kill the whitespace.. kill the whitespace..Theo de Raadt
2015-11-01chroot to pw_dir instead of the hard-coded /var/empty. Also make theReyk Floeter
chroot+chdir step look more like in the other privsep daemons. OK tedu@
2015-10-30it 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
2015-10-29put timeout nullification in correct spotTed Unangst
2015-10-29be a little more precise about checking filtersTed Unangst
2015-10-29refold a few linesTed Unangst
2015-10-29collect some cool stats and print them out with SIGUSR1Ted Unangst
2015-10-28impose some limit on the cache size as well.Ted Unangst
2015-10-28if accept() fails due to fd exhaustion, stop accepting for one second.Ted Unangst
should only happen for ENFILE, but check for EMFILE too.
2015-10-28bug in the request tree code: requests were being added to the tree beforeTed Unangst
the socket (the key) was being set. move the enqueue code later, and fix freerequest to only dequeue if socket is set.
2015-10-28twiddle with rlimit to give us a few more files. use rlimit as a hint asTed 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.
2015-10-28add pledge to main process, though it needs a few more optionsTed Unangst
2015-10-28use an rb tree for the cache too. modelled after the reqtree.Ted Unangst
2015-10-28use an rb tree for finding requests. from Dimitris PapastamosTed Unangst
2015-10-26one second amnesty for timeouts so we don't spin with short timeoutsTed Unangst
2015-10-26set listening sockets to nonblocking, then handle as many incoming requestsTed Unangst
as we can in the loop instead of keventing per request.
2015-10-17don't need fcntl for non blocking socket, just ask for it upfrontTed Unangst
2015-10-16save some file descriptors. instead of a pipe, use kevent to watch parentTed Unangst
2015-10-16naddy 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.
2015-10-16life is simpler if all requests go in the fifo, and then just remove themTed Unangst
in the error case instead of duplicating code.
2015-10-16deraadt tells me i'm supposed to check if connect() actually worked.Ted Unangst
