We used to not set the guard state in launch_direct_bridge_descriptor_fetch().
So when a bridge descriptor fetch failed, the guard subsystem would never
learn about the fail (and hence the guard's reachability state would not
be updated).

Directory authorities now reject relays running versions
0.2.9.1-alpha through 0.2.9.4-alpha, because those relays
suffer from bug 20499 and don't keep their consensus cache
up-to-date.
Resolves ticket 20509.
This gives an indication in the log that Tor was built with Rust
support, as well as laying some groundwork for further string-returning
APIs to be converted to Rust
config_get_lines is now split into two functions:
- config_get_lines which is the same as before we had %include
- config_get_lines_include which actually processes %include
Before we've set our options, we can neither call get_options() nor
networkstatus_get_latest_consensus().
Fixes bug 22252; bugfix on 4d9d2553ba
in 0.2.9.3-alpha.
Replace the 177 fallbacks originally introduced in Tor 0.2.9.8 in
December 2016 (of which ~126 were still functional), with a list of
151 fallbacks (32 new, 119 existing, 58 removed) generated in May 2017.
Resolves ticket 21564.
This patch makes us use FALLBACK_COMPRESS_METHOD to try to fetch an
object from the consensus diff manager in case no mutually supported
result was found. This object, if found, is then decompressed using the
spooling system to the client.
See: https://bugs.torproject.org/21667
This patch removes the calls to spooled_resource_new() when trying to
download the consensus. All calls should now be going through the
consdiff manager.
See: https://bugs.torproject.org/21667
This patch ensures that we use the current consensus in the case where
no consensus diff was found or a consensus diff wasn't requested.
See: https://bugs.torproject.org/21667
These still won't do anything till I get the values to be filled in.
Also, I changed the API a little (with corresponding changes in
directory.c) to match things that it's easier to store.
This patch changes handle_get_current_consensus() to make it read the
current consensus document from the consensus caching subsystem.
See: https://bugs.torproject.org/21667
Failure to do this caused an assertion failure with #22246 . This
assertion failure can be triggered remotely, so we're tracking it as
medium-severity TROVE-2017-002.
Closes bug 22245; bugfix on 0.0.9rc1, when bandwidth accounting was
first introduced.

This patch refactors connection_dir_client_reached_eof() to use
compression_method_get_human_name() to set description1 and
description2 variables.

One (HeapEnableTerminationOnCorruption) is on-by-default since win8;
the other (PROCESS_DEP_DISABLE_ATL_THUNK_EMULATION) supposedly only
affects ATL, which (we think) we don't use. Still, these are good
hygiene. Closes ticket 21953.
A descriptor only contains the curve25519 public key in the enc-key field so
the private key should not be in that data structure. The service data
structures will have access to the full keypair (#20657).
Furthermore, ticket #21871 has highlighted an issue in the proposal 224 about
the encryption key and legacy key being mutually exclusive. This is very wrong
and this commit fixes the code to follow the change to the proposal of that
ticket.

We do this by treating the presence of .z as meaning ZLIB_METHOD,
even if Accept-Encoding does not include deflate.
This fixes bug 22206; bug not in any released tor.
Nothing was setting or inspecting these fields, and they were marked
as OBSOLETE() in config.c -- but somehow we still had them in the
or_options_t structure. Ouch.
There was a bug that got exposed with the removal of ORListenAddress. Within
server_mode(), we now only check ORPort_set which is set in parse_ports().
However, options_validate() is using server_mode() at the start to check if we
need to look at the uname but then the ORPort_set is unset at that point
because the port parsing was done just after. This commit fixes that.

This change prevents a no-longer-supported behavior where we change
options that would later be written back to torrc with a SAVECONF.
Also, use the "Pointer to final pointer" trick to build the
normalized list, to avoid special-casing the first element.
Checking all of these parameter lists for every single connection every second
seems like it could be an expensive waste.
Updating globally cached versions when there is a new consensus will still
allow us to apply consensus parameter updates to all existing connections
immediately.
Accomplished via the following:
1. Use NETINFO cells to determine if both peers will agree on canonical
status. Prefer connections where they agree to those where they do not.
2. Alter channel_is_better() to prefer older orconns in the case of multiple
canonical connections, and use the orconn with more circuits on it in case
of age ties.
Also perform some hourly accounting on how many of these types of connections
there are and log it at info or notice level.
This unifies CircuitIdleTimeout and PredictedCircsRelevanceTime into a single
option, and randomizes it.
It also gives us control over the default value as well as relay-to-relay
connection lifespan through the consensus.

This defense will cause Cisco, Juniper, Fortinet, and other routers operating
in the default configuration to collapse netflow records that would normally
be split due to the 15 second flow idle timeout.
Collapsing these records should greatly reduce the utility of default netflow
data for correlation attacks, since all client-side records should become 30
minute chunks of total bytes sent/received, rather than creating multiple
separate records for every webpage load/ssh command interaction/XMPP chat/whatever
else happens to be inactive for more than 15 seconds.
The defense adds consensus parameters to govern the range of timeout values
for sending padding packets, as well as for keeping connections open.
The defense only sends padding when connections are otherwise inactive, and it
does not pad connections used solely for directory traffic at all. By default
it also doesn't pad inter-relay connections.
Statistics on the total padding in the last 24 hours are exported to the
extra-info descriptors.
Right now it just sets an if-modified-since header, but it's about
to get even bigger.
This patch avoids changing indentation; the next patch will be
whitespace fixes.
We need to index diffs by the digest-as-signed of their source
consensus, so that we can find them even from consensuses whose
signatures are encoded differently.
In this patch I add support for "delete through end of file" in our
ed diff handler, and generate our diffs so that they remove
everything after in the consensus after the signatures begin.
This was introduced 90562fc23a adding a code
path where we pass a NULL pointer for the HSDir fingerprint to the control
event subsystem. The HS desc failed function wasn't handling properly that
pointer for a NULL value.
Two unit tests are also added in this commit to make sure we handle properly
the case of a NULL hsdir fingerprint and a NULL content as well.
Fixes#22138

config_parse_interval() and config_parse_msec_interval() were checking
whether the variable "ok" (a pointer to an int) was null, rather than
derefencing it. Both functions are static, and all existing callers
pass a valid pointer to those static functions. The callers do check
the variables (also confusingly named "ok") whose addresses they pass
as the "ok" arguments, so even if the pointer check were corrected to
be a dereference, it would be redundant.
Fixes#22103.
This was a >630-line function, which doesn't make anybody happy. It
was also mostly composed of a bunch of if-statements that handled
different directory responses differently depending on the original
purpose of the directory connection. The logical refactoring here
is to move the body of each switch statement into a separate handler
function, and to invoke those functions from a separate switch
statement.
This commit leaves whitespace mostly untouched, for ease of review.
I'll reindent in the next commit.
