using bridges or we have StrictEntryNodes set), don't mark relays
down when they fail a directory request. Otherwise we're too quick
to mark all our entry points down.

authorities to mark certain relays as "bad directories" in the
networkstatus documents. Also supports the "!baddir" directive in
the approved-routers file.
svn:r12754
downloading new consensus documents. Bridge users now wait until
the end of the interval, so their bridge will be sure to have a
new consensus document.
svn:r12696
running an obsolete version, it used the string "OLD" to describe
it. Yet the "getinfo" interface used the string "OBSOLETE". Now use
"OBSOLETE" in both cases.
svn:r12686
on but your ORPort is off.
Add a new config option BridgeRelay that specifies you want to
be a bridge relay. Right now the only difference is that it makes
you answer begin_dir requests, and it makes you cache dir info,
even if your DirPort isn't on.
Refactor directory_caches_dir_info() into some more functions.
svn:r12668
Change tor_addr_t to be a tagged union of in_addr and in6_addr, not of sockaddr_in and sockaddr_in6. It's hardly used in the main code as it is, but let's get it right before it gets popular.
svn:r12660
that have no introduction points. But Tor crashed when we tried
to build a descriptor with no intro points (and it would have
crashed if we had tried to parse one). Bugfix on 0.2.0.x; patch
by Karsten Loesing.
svn:r12579
enough directory information. This was causing us to always pick
two new guards on startup (bugfix on 0.2.0.9-alpha), and it was
causing us to discard all our guards on startup if we hadn't been
running for a few weeks (bugfix on 0.1.2.x). Fixes bug 448.
svn:r12570
When authorities detected more than two relays running on the same
IP address, they were clearing all the status flags but forgetting
to clear the "hsdir" flag. So clients were being told that a
given relay was the right choice for a v2 hsdir lookup, yet they
never had its descriptor because it was marked as 'not running'
in the consensus.
svn:r12515
the bridge authority could help us (for example, we don't know
a digest, or there is no bridge authority), don't be so eager to
fall back to asking the bridge authority.
svn:r12512
non-running hsdirs, or not give them the flag if they're not running,
or what.
When picking v2 hidden service directories, don't pick ones that
aren't listed as Running.
svn:r12509
relay's public (external) IP address too, unless
ExitPolicyRejectPrivate is turned off. We do this because too
many relays are running nearby to services that trust them based
on network address.
svn:r12459
Mess with the formula for the Guard flag again. Now it requires that you be in the most familiar 7/8 of nodes, and have above median wfu for that 7/8th. See spec for details. Also, log thresholds better.
svn:r12440
If setting our rlimit to rlim_max or cap fails, fall back to OPEN_FILES if defiled. This makes Tor run on OSX 10.5, while allowing OSX to mend its ways in the future.
svn:r12341
As an authority, send back an X-Descriptor-Not-New header when we accept but do not store a descriptor. Partial implementation of fix for bug 535.
svn:r12310
Improved skew reporting: "You are 365 days in the duture" is more useful than "You are 525600 minutes in the future". Also, when we get something that proves we are at least an hour in the past, tell the controller "CLOCK_SKEW MIN_SKEW=-3600" rather than just "CLOCK_SKEW"
svn:r12283
Tidy v2 hidden service descriptor format code: fix memory leaks, fix reference problems, note magic numbers, note questions, remove redundant checks, remove a possible stack smashing bug when encoding a descriptor with no protocols supported.
svn:r12255
edge_connection_t: want_onehop if it must attach to a circuit with
only one hop (e.g. for the current tunnelled connections that use
begin_dir), and use_begindir if we mean to use a BEGIN_DIR relay
command to establish the stream rather than the normal BEGIN. Now
we can make anonymized begin_dir connections for (e.g.) more secure
hidden service posting and fetching.
svn:r12244
Stop servers from crashing if they set a Family option (or
maybe in other situations too). Bugfix on 0.2.0.9-alpha; reported
by Fabian Keil.
svn:r12235
Keep circuitless TLS connections open for 1.5 x MaxCircuitDirtiness: this ensures that we don't thrash closing and repoening connections to our guards.
svn:r12218
Fix logic for downloading consensuses: make getting an duplicate or not-currently-valid consensus count as a failure. Make running out of time to get certificates count as a failure. Delay while fetching certificates.
svn:r12159
Refactor the arguments for router_pick_{directory_|trusteddir}server[_impl] so that they all take the same flags, and so that their flags have names. Fix their documentation too.
svn:r12157
minutes, but writing the "valid-after" line in our vote based
on our configured V3AuthVotingInterval: so unless the intervals
matched up, we immediately rejected our own vote because it didn't
start at the voting interval that caused us to construct a vote.
This caused log entries like:
Oct 23 01:16:16.303 [notice] Choosing expected valid-after time
as 2007-10-23 05:30:00: consensus_set=0, interval=1800
...
Oct 23 01:20:01.203 [notice] Choosing valid-after time in vote as
2007-10-23 06:00:00: consensus_set=0, interval=3600
Oct 23 01:20:01.290 [warn] Rejecting vote with valid-after time of
2007-10-23 06:00:00; we were expecting 2007-10-23 05:30:00
Oct 23 01:20:01.291 [warn] Couldn't store my own vote! (I told
myself, 'Bad valid-after time'.)
Nick, you should look at this, as it's your design. :)
svn:r12129
Respond to INT and TERM SIGNAL commands before we execute the
signal, in case the signal shuts us down. We had a patch in
0.1.2.1-alpha that tried to do this by queueing the response on
the connection's buffer before shutting down, but that really
isn't the same thing. Bug located by Matt Edman.
This is a bug in 0.1.2.x too, but there's no way we should backport
this fix. Speaking of which, can somebody double-check it? :)
svn:r12070
Remember the valid-until time of the most recent consensus that listed
a router, and (if we are a cache) never delete the routerdesc until
that conensus is expired. This is way easier than retaining multiple
consensuses. (Of course, the info isn't retained across restarts,
but that only affects a few caches at a time.)
svn:r12041
When a networkstatus consensus download fails, do not wait 60 seconds to decide whether to retry. (Also, log the time at which we'll try to replace the current networkstatus.)
svn:r12005
oprofile was telling me that a fair bit of our time in openssl was spent in base64_decode, so replace base64_decode with an all-at-once fairly optimized implementation. For decoding keys and digests, it seems 3-3.5x faster than calling out to openssl. (Yes, I wrote it from scratch.)
svn:r12002
Make unverified-consensus get removed when it is accepted or rejected. Make a new get_datadir_fname*() set of functions to eliminate the common code of "get the options, get the datadir, append some stuff".
svn:r12000
Implement v3 networkstatus client code. Remove v2 networkstatus client code, except as needed for caches to fetch and serve v2 networkstatues and the routers they list.
svn:r11957
Make discard_old_votes part of the consensus publishing process, so we conform to spec, and so we avoid a weird bugs where publishing sets the consensus, setting the consensus makes us reschedule, and rescheduling makes us delay vote-discarding.
svn:r11944
when we find our DirPort to be reachable but won't actually publish
it. Extra descriptors without any real changes are dropped by the
authorities, and can screw up our "publish every 18 hours" schedule.
svn:r11915
Fix bug 451. This was a nasty bug, so let's fix it twice: first, by banning recursive calls to connection_handle_write from connection_flushed_some; and second, by not calling connection_finished_flushing() on a closed connection. Backport candidate.
svn:r11882
Fix a bunch of XXX020s: treat some 403s as INFO severity; remove some dead code; share the retry path for consensus routerdescs that are also listed in the v2 networkstatus; check even more aspects of votes when parsing them.
svn:r11871
Fix the implementation of if-modified-since for certificates so that it applies to all types of certificate requests. Note that the kind of consensus that matters already has a working if-modified-since.
svn:r11852
Fix some memory leaks when serving v3 networkstatus documents and v3 certs. Generate 503 correctly when serving v3 networkstatus documents and v3 certs.
svn:r11850
Retry consensus and certificate downloads properly. Do not fail when there are no certificates to download. Do not download certificates we already have when retrying.
svn:r11841
Save weighted-fractional-uptime to disk as well as MTBF. Bump the version on rouer-stability: downgrading to versions earlier than this one will lose your WFU data.
svn:r11835
Fix the bug that was making moria1 set valid-after wrong in its votes: we were looking at the preferred timing when we should have been looking at the consensus timing.
svn:r11818
Use download_status_t for v2 networkstatuses and certs as well as for routers. Make functions to manipulate it. Next steps: use it for consensus networkstatuses, and get consensus download rescheduling working.
svn:r11800
Refactor out about a third of routerlist.c into a new networkstatus.c. I\m not sure that I got everything that needed to move, but so far so good.
svn:r11791
Use descriptor annotations to record the source, download t time, and purpose of every descriptor we add to the store. The remaining to-do item is to stop setting do_not_cache on bridges.
svn:r11680
Remove annotated_desc_store store (which we never used). Instead, shift name of router store to cached-descriptors, but initialize it from cached-routers as needed
svn:r11678
Fix a stupid logic error in authority_cert_get_by_sk_digest: the presence of an authority lacking a v3 cert does not mean that subsequent authorities lack them too.
svn:r11668
users configure that and specify a bridge with an identity
fingerprint, now they will lookup the bridge descriptor at the
default bridge authority via a one-hop tunnel, but once circuits
are established they will switch to a three-hop tunnel for later
connections to the bridge authority.
svn:r11550
Fix a bug that made servers send a "404 Not found" in response to
attempts to fetch their server descriptor. This caused Tor servers
to take many minutes to establish reachability for their DirPort,
and it totally crippled bridges. Bugfix on 0.2.0.5-alpha.
svn:r11545
Re-optimize counter-mode: save about 15% on my core2 by (1) not regenerating the entire counter buffer every time we encrypt a block of keystream (2) using the platform-optimized htonl to convert to big-endian (It's a single instruction on 486 and later ) and (3) not even keeping a separate "counter" and "buffer" when the platform is big-endian. The third still needs testing.
svn:r11536
clients specify their chosen rendezvous point by identity digest
rather than by (potentially ambiguous) nickname. This change could
speed up hidden service connections dramatically.
svn:r11499
Get rid of a needless malloc() when parsing address policies. Original patch from "Some guy on #tor", via arma. Altered to have a sufficiently large buffer, and not use the buffer so much, and to save a strlcpy.
svn:r11480
BandwidthRate, RelayBandwidthRate, or MaxAdvertisedBandwidth
were below a threshold. Now they only look at BandwidthRate and
RelayBandwidthRate.
