Clean up MTBF storage code. Do not count times that we have been down toward the current run. Handle backward timewarps correctly. Store MTBF data on exit in addition to periodically.

- If we require CookieAuthentication but we fail to write the
cookie file, we would warn but not exit, and end up in a state
where no controller could authenticate. Now we exit.
- If we require CookieAuthentication, stop generating a new cookie
every time we change any piece of our config.
svn:r11117
Another patch from croup: drop support for address masks that do not correspond to bit prefixes. Nobody has used this for a while, and we have given warnings for a long time.
svn:r10881
Tweaks on constrained socket buffers patch from coderman: Add a changelog; rename some variables; fix some long lines and whitespace; make ConstrainedSockSize a memunit; pass setsockopt a void.
svn:r10843
fix copy-paste error in config message src/or/config.c . Apply
initial (but pared-down) version of launch-resolve-via-controller
patch from Robert Hogan.
svn:r10780
Sun CC likes to give warnings for the do { } while(0) construction for making statement-like macros. Define STMT_BEGIN/STMT_END macros that do the right thing, and use them everywhere.

- demand options->Bridges and options->TunnelDirConns if
options->UseBridges is set.
- after directory fetches, accept descriptors that aren't referenced by
our networkstatuses, *if* they're for a configured bridge.
- delay directory fetching until we have at least one bridge descriptor.
- learn how to build a one-hop circuit when we have neither routerinfo
nor routerstatus for our destination.
- teach directory connections how to pick a bridge as the destination
directory when doing non-anonymous fetches.
- tolerate directory commands for which the dir_port is 0.
- remember descriptors when the requested_resource was "authority",
rather than just ignoring them.
- put bridges on our entry_guards list once we have a descriptor for them.
When UseBridges is set, only pick entry guards that are bridges. Else
vice versa.

Well, that was easier than I thought it would be. Tor is now a DNS proxy as well as a socks proxy. Probably some bugs remain, but since it A) has managed to resolve one address for me successfully, and B) will not affect anybody who leaves DNSPort unset, it feel like a good time to commit.
svn:r10317
backport candidate: Warn when using a version of libevent before 1.3b to run a server on osx or bsd: these versions of libevent interact badly with userspace threads.
svn:r10307
More v3 directory code: have authorities load certificates; have everybody store certificates to disk and load them; provide a way to configure v3 authorities.
svn:r10293
It is becoming increasingly clear to me that bridges should
be a special case of entry guards, not a whole separate pile
of nearly identical functions.
svn:r10141
authorities should set. This will let future authorities choose
not to serve V2 directory information.
Also, go through and revamp all the authdir_mode stuff so it tries
to do the right thing if you're an auth but not a V1 or V2 auth.
svn:r10092
Initial version of patch from Karsten Loesing: Add an HSAuthorityRecordStats option to track statistics of overall hidden service usage without logging information that would be useful to an attacker.
svn:r10067
Add code to shrink the cell memory pool by discarding empty chunks that have been empty for the last 60 seconds. Also, instead of having test.c duplicate declarations for exposed functions, put them inside #ifdef foo_PRIVATE blocks in the headers. This prevents bugs where test.c gets out of sync.
svn:r9944
Make all LD_BUG log messsages get prefixed with "Bug: ". Remove manually-generated "Bug: "s from log-messages. (Apparently, we remembered to add them about 40% of the time.)
svn:r9733
Niels has accepted the patch from Scott Lamb to implement better signal handling: I can take "get the pthread_sigprocmask situation under control" off my plate.
svn:r9696
Move all struct-offset-manipulation macros into util.h, and use them consistently. Because there are days when "SUBTYPE_P(handle, subtype, _base)" is just easier to read and write than "(basetp*)(((handle) - STRUCT_OFFSET(subtype, _base))".
svn:r9592
Resolve some XXXX012 items:
- Remove PathlenCoinWeight: if we want it again, we can add it
back in.
- Ditto with RelayBandwidth*.
- Decide to leave in the "hey, you didn't set end_reason!" BUG log message,
but stop telling people to bug me personally.
- Postpone strengthening assert_connection_ok(): it's important, but
it's also a good way to introduce weird bugs.
- Move some expensive consistency checking from dns_free_all() into
assert_cache_ok().
svn:r9533
Removing the last DOCDOC comment hurt so much that I had to use Doxygen to identify undocumented macros and comments, and add 150 more DOCDOCs to point out where they were. Oops. Hey, kids! Fixing some of these could be your first Tor patch!
svn:r9477
Check addresses for rfc953-saneness at exit too, and give a PROTOCOL_WARN when they fail. Also provide a mechanism to override this, so blossom can have its @@##$$^.whatever.exit hostnames if it wants.
svn:r9336
Implement a control status event for bad libevent version/method combos. Warn that libevent <1.1 with select() is needlessly slow. Reply to comment.
svn:r9284
Fix bug 364: check for whether popular hostnames (curently google, yahoo, mit, and slashdot) are getting wildcarded. If they are, we are probably behind a DNS server that is useless: change our exit policy to reject *:*.
svn:r9199
Add an orport option to dirserver lines so that clients can tell where to connect to open an encrypted tunnel to a dirserver even before they have its descriptor.
svn:r9171
Add a maintainer script and a new make target "make check-docs" to get a quick dump of which options are undocumented where, and which documentation refers to nonexistent options.
svn:r9160
Add internal documentation for a bunch of configuration options. We should do something to keep this list, the canonical list, the tor.1 list, and the torrc.complete list in sync.
svn:r9133
Add a LastRotatedOnionKey variable to the state file, so we can rotate onion keys a week after they change even if we never stay up for a whole week at a time. Should fix bug 368.
svn:r9120
Resolve bug 369: Check for integer underflow when printing "bytes left" accounting numbers. Also fix a copyright date that I noticed while reading the bug. Also make a buffer big enough that strings will not get truncated. All are backport candidates.
svn:r9115
New socks command CONNECT_DIR. New config option TunnelDirConns that
builds a circ ending at the directory server and delivers a BEGIN_DIR
cell if it's running 0.1.2.2-alpha or later. We still need to make
one-hop circs when appropriate, while making other conns avoid them.
svn:r9098
Revise logic used to flush state to disk. Now, we try to batch non-urgent changes so that we do not do too many writes, and we save very-non-urgent changes every once in a rare while, and we never save more than once per second.
svn:r9047
Change logging format of state file to only include non-default values. Adjust clients to never store bandwidth history in the state file. (Possible backport candidate.)
svn:r9043
Try to compile with fewer warnings on irix64's MIPSpro compiler /
environment, which apparently believes that:
- off_t can be bigger than size_t.
- only mean kids assign things they do not subsequently inspect.
I don't try to fix the "error" that makes it say:
cc-3970 cc: WARNING File = main.c, Line = 1277
conversion from pointer to same-sized integral type (potential portability
problem)
uintptr_t sig = (uintptr_t)arg;
Because really, what can you do about a compiler that claims to be c99
but doesn't understand that void* x = NULL; uintptr_t y = (uintptr_t) x;
is safe?
svn:r8948
Add support for (Free?)BSD's natd, which was an old way to let you
have your firewall automatically redirect traffic. (Original patch
from Zajcev Evgeny, updated for 0.1.2.x by tup.)
svn:r8946
Let directory authorities set the BadExit flag if they like. Also, refactor directory authority code so we can believe multiple things about a single router, and do fewer linear searches.
svn:r8794
Add unit tests for tor_mmap_file(); make tor_mmap_t.size always be the size of the file (not the size of the mapping); add an extra argument to read_file_to_str() so it can return the size of the result string.
svn:r8762
Apply patch from Mike Perry: add more reasons for circuit destroys. (Slightly tweaked to avoid allocating a number for an "internal" reason.)
svn:r8739
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
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
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
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
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
