Add client support for a 'BadExit' flag, so authorities can say "Server X is a poor choise for your nytimes.com connections, as it seems to direct them to HoorayForMao.com or (more likely) WouldYouLikeToBuyTheseFineEncyclopedias.com"

Touch up last patch (to add REASON to CIRC events): make some reasons
more sensible, send reasons only to controllers that have enabled
extended events, and clean up whitespace.
svn:r8672
Win32 patch from Matt Edman: fix compilation bugs by casting to int; defining SSIZE_T; defining USE_TWOS_COMPLEMENT in windows orconfig.h; and using the proper names for win32 functions on GetProcAddress. Also fixes bug 295.
svn:r8669
The otherwise regrettable MIPSpro C compiler warns about values set but never used, and about mixing enums and ints; these are good warnings, and so should be fixed. This removes some dead code and some potential bugs. Thanks to pnx.
svn:r8664
Try to make mingw capable of producing a working tor binary for win98: make all NT-service-related functions get lazy-loaded on demand. I have no idea if this even compiles.
svn:r8643
around some housecleaning calls so they still occur often.
are some of these redundant or in the wrong order? there are
so many of them, maybe they should be put into a separate
function that has better documentation.

We're trying to catch the kind of jerk who'd hijack zy6pzwohtnlq.test,
not the kind of lunatic who'd hijack zy6pzwohtnlq%s.test, though
apparently those exist too.
svn:r8595
Add USEFEATURE to control changes to control protocol. Use like __future__ directive from Python. Will spec before pushing changes. No, really. :)
svn:r8584
Partial implementation of revised nickname syntax for controllers. Implement ability to look up routers by "verbose" nicknames; add a per-v1-control-connection flag to turn the feature on in events. Needs testing, spec, ability to actually turn on the flag, double-checking that we wont overflow any nickname buffers, and changelog.
svn:r8582
Remove/clarify some XXXs for no longer being accurate; for begin things we do not indend to fix; for already being parts of big todo issues (like "/* XXX ipv6 */"); etc. Also fix some spaces.
svn:r8580
Make TrackExitHosts case-insensitive, and fix the behavior of .suffix TrackExitHosts items to avoid matching in the middle of an address. (Resolves an XXXX)
svn:r8579
Move is_local_IP to config.c; have it check for same-/24; make it used only for reachability (not for banwidth, because that is probably not what we want). Fixes an XXX.
svn:r8578
hidden service authorities too.
- Just because your DirPort is open doesn't mean people should be
able to remotely teach you about hidden service descriptors. Now
only accept rendezvous posts if you've got HSAuthoritativeDir set.
svn:r8573
Disprefer exit nodes for entry, middle positions (fixes bug 200). Also, switch to using a uint64_t to hold "total bandwidth for all nodes" under consideration; crypt_rand_int would have died at 2GB/s network capacity.
svn:r8571
Reserve the nickname "Unnamed" for routers that can't pick a hostname; any
router can call itself Unnamed; directory servers will never allocate Unnamed
to any particular router; clients won't believe that any router is the
canonical Unnamed.
svn:r8529
[Needs review.] Add a BEGIN_DIR relay cell type for an easier
in-protocol way to connect to directory servers through Tor.
Previously, clients could only connect to director servers over Tor
from exit nodes, but couldn't get directory information anonymously
from a non-exit cache without getting a directory server involved.
This needs testing, and needs client-side code to actually exercise it.
svn:r8527
Make "is a v1 authority", "is a v2 authority", and "is a hidden service authority" into separate flags so we can eventually migrate more trust away from moria.
svn:r8523
Another tweak to guard logic: ignore check for the Guard flag if a server is listed on EntryNodes. (Also remove redundant checks for always-set variables.)
svn:r8522
Improvement to last entry guards patch: track when we last attempted to connect to a node in our state file along with how long it has been unreachable. Also clarify behavior of parse_iso_time() when it gets extra characters.
svn:r8520
Refactor entry guard status logic a lot; allow more factors [like not
having a Guard flag or being listed in ExcludeNodes] to render a guard
"unlisted" (now called "unusable"); track guard down status (now
called "unreachable") separately from is_running.
svn:r8519
router_set_networkstatus() gets a list of status documents we asked for from
connection_dir_client_reached_eof(). However, as a cache we (sometimes?) just
ask for "all". router_set_networkstatus() would freak out over that, meaning
it would log a warning and drop the status document instead of caching it
as it is supposed to. Now we let router_set_networkstatus() know if the
data comes from an all-request so it can do the right thing.
svn:r8513
client asks us to resolve (not connect to) an address, and we have a
cached answer, give them the cached answer. Previously, we would give
them no answer at all.
svn:r8478
Instead of just checking known-invalid addresses for DNS hijacking, we
now check randomly generated addresses, and if too many of them map to
the same IP, we assume that IP is the destination of a DNS hijack
attempt.
A little bird tells me that some DNS hijackers think that declining to
give an A record for RFC2606 addresses (like .invalid and .example)
makes them more standards compliant. Standardswise, this is like an
illicit brothel making sure that nobody has pulled the tags off the
mattresss, but that doesn't get us out of working around it.
svn:r8465
I tracked a bug in server-side reverse DNS to something concerning the caching code. Ive disabled server-side cacheing for reverse DNS answers for now, and I am noting the bug in the TODO.
