6215ebb266 Reduce log severity for unused ClientTransportPlugin lines
Tor Browser includes several ClientTransportPlugin lines in its
torrc-defaults file, leading every Tor Browser user who looks at her
logs to see these notices and wonder if they're dangerous.

Resolves bug 13124; bugfix on 0.2.5.3-alpha.

3c2c6a6116 In routerlist_assert_ok(), check r2 before taking &(r2->cache_info)
Technically, we're not allowed to take the address of a member can't
exist relative to the null pointer.  That makes me wonder how any sane
compliant system implements the offsetof macro, but let's let sleeping
balrogs lie.

Fixes 13096; patch on 0.1.1.9-alpha; patch from "teor", who was using
clang -fsanitize=undefined-trap -fsanitize-undefined-trap-on-error -ftrapv

efcab43956 Fix a number of clang analyzer false-positives
Most of these are in somewhat non-obvious code where it is probably
a good idea to initialize variables and add extra assertions anyway.

7a878c192f Downgrade "Unexpected onionskin length after decryption" warning

37a76d75dd Resume expanding abbreviations for command-line options
The fix for bug 4647 accidentally removed our hack from bug 586 that
rewrote HashedControlPassword to __HashedControlSessionPassword when
it appears on the commandline (which allowed the user to set her own
HashedControlPassword in the torrc file while the controller generates
a fresh session password for each run).

1196ed7cc4 Fix relay_command_to_string(); solve 12700.
Two bugs here:
  1) We didn't add EXTEND2/EXTENDED2 to relay_command_to_string().

  2) relay_command_to_string() didn't log the value of unrecognized
     commands.

Both fixed here.

0808ed83f9 Restore functionality for CookieAuthFileGroupReadable.
When we merged the cookieauthfile creation logic in 33c3e60a37, we
accidentally took out this feature.  Fixes bug 12864, bugfix on
0.2.5.1-alpha.

Also adds an ExtORPortCookieAuthFileGroupReadable, since there's no
reason not to.

0044d74b3c Fix another case of 12848 in circuit_handle_first_hop
I looked for other places where we set circ->n_chan early, and found
one in circuit_handle_first_hop() right before it calls
circuit_send_next_onion_skin(). If onion_skin_create() fails there,
then n_chan will still be set when circuit_send_next_onion_skin()
returns. We should probably fix that too.

fcac4b4467 Build circuits more readily when DisableNetwork goes to 0
When Tor starts with DisabledNetwork set, it would correctly
conclude that it shouldn't try making circuits, but it would
mistakenly cache this conclusion and continue believing it even
when DisableNetwork is set to 0. Fixes the bug introduced by the
fix for bug 11200; bugfix on 0.2.5.4-alpha.

68a2e4ca4b Warn and drop the circuit if we receive an inbound 'relay early' cell
Those used to be normal to receive on hidden service circuits due to bug
1038, but the buggy Tor versions are long gone from the network so we
can afford to resume watching for them. Resolves the rest of bug 1038;

d5558f0072 circuit_build_failed: distinguish "first hop chan failed", "CREATE failed"

network timeout indicating failure but not overload indicating failure.)

a57c07b210 Raise guard threshold to top 25% or 2000 kilounits
Authorities now assign the Guard flag to the fastest 25% of the
network (it used to be the fastest 50%). Also raise the consensus
weight that guarantees the Guard flag from 250 to 2000. For the
current network, this results in about 1100 guards, down from 2500.
This step paves the way for moving the number of entry guards
down to 1 (proposal 236) while still providing reasonable expected
performance for most users.

Implements ticket 12690.

d504a4e36f src/or/connection.c: expose bucket_millis_empty for bufferevents test
Currently tor fails to build its test when enabled with bufferevents
because an #ifndef USE_BUFFEREVENTS hides bucket_millis_empty() and
friends.  This is fine if we don't run tests, but if we do, we need
these functions in src/or/libtor-testing.a when linking src/test/test.

This patch moves the functions outside the #ifndef and exposes them.

was at least correct.

f9f450d688 Also raise the check for 0 circuit ID in created cell.
And add a comment about why conditions that would cause us to drop a
cell should get checked before actions that would cause us to send a
destroy cell.

Spotted by 'cypherpunks'.

And note that these issues have been present since 0.0.8pre1 (commit
0da256ef), where we added a "shutting down" state, and started
responding to all create cells with DESTROY when shutting down.
