3ff092391b Apply Roger's bug 1269 fix.
From http://archives.seul.org/tor/relays/Mar-2010/msg00006.html :

   As I understand it, the bug should show up on relays that don't set
   Address to an IP address (so they need to resolve their Address
   line or their hostname to guess their IP address), and their
   hostname or Address line fails to resolve -- at that point they'll
   pick a random 4 bytes out of memory and call that their address. At
   the same time, relays that *do* successfully resolve their address
   will ignore the result, and only come up with a useful address if
   their interface address happens to be a public IP address.

2917c0596c Restrict PerConnBWRate|Burst to INT32_MAX, update manpage
All other bandwidthrate settings are restricted to INT32_MAX, but
this check was forgotten for PerConnBWRate and PerConnBWBurst. Also
update the manpage to reflect the fact that specifying a bandwidth
in terabytes does not make sense, because that value will be too
large.

d35b8dc582 Make expand_filename into a tor_strdup() alias on windows.
On Windows, we don't have a notion of ~ meaning "our homedir", so we
were deliberately using an #ifdef to avoid calling expand_filename()
in multiple places.  This is silly: The right place to turn a function
into a no-op on a single platform is in the function itself, not in
every single call-site.

a168cd2a54 Don't use gethostbyname() in resolve_my_address()
Tor has tor_lookup_hostname(), which prefers ipv4 addresses automatically.
Bug 1244 occured because gethostbyname() returned an ipv6 address, which
Tor cannot handle currently. Fixes bug 1244; bugfix on 0.0.2pre25.

ef81649d2f Be more willing to use an unsuitable circuit for exit.
Specifically, there are two cases: a) are we willing to start a new
circuit at a node not in your ExitNodes config option, and b) are we
willing to make use of a circuit that's already established but has an
unsuitable exit.

Now we discard all your circuits when you set ExitNodes, so the only
way you could end up with an exit circuit that ends at an unsuitable
place is if we explicitly ran out of exit nodes, StrictNodes was 0,
and we built this circuit to solve a stream that needs solving.

Fixes bug in dc322931, which would ignore the just-built circuit because
it has an unsuitable exit.

580066f2f6 Switch to a StrictNodes config option.
This is step one of handling ExcludedNodes better. This first
step is just to make EntryNodes and ExitNodes do what they did
before.

d38268a8c7 Remove v0 hidden service statistics code.
The HSAuthorityRecordStats option was used to track statistics of overall
hidden service usage on the version 0 hidden service authorities. With the
version 2 hidden service directories being deployed and version 0
descriptors being phased out, these statistics are not as useful anymore.

Goodbye, you fine piece of software; my first major code contribution to

fcbd65b45c Refactor the safe_str_*() API to make more sense.
The new rule is: safe_str_X() means "this string is a piece of X
information; make it safe to log."  safe_str() on its own means
"this string is a piece of who-knows-what; make it safe to log".

60b01c6d5e Change interface for configuring cell ewma algorithm.
The rule is now: take the value from the CircuitPriorityHalflife
config option if it is set.  If it zero, disable the cell_ewma
algorithm.  If it is set, use it to calculate the scaling factor.
If it is not set, look for a CircPriorityHalflifeMsec parameter in the
consensus networkstatus.  If *that* is zero, then disable the cell_ewma
algorithm; if it is set, use it to calculate the scaling factor.
If it is not set at all, disable the algorithm.

06e8370c33 Optimize cell-ewma circuit priority algorithm.
There are two big changes here:
  - We store active circuits in a priority queue for each or_conn,
    rather than doing a linear search over all the active circuits
    before we send each cell.
  - Rather than multiplying every circuit's cell-ewma by a decay
    factor every time we send a cell (thus normalizing the value of a
    current cell to 1.0 and a past cell to alpha^t), we instead
    only scale down the cell-ewma every tick (ten seconds atm),
    normalizing so that a cell sent at the start of the tick has
    value 1.0).

d3be00e0f4 Favor quiet circuits when choosing which order to relay cells in.
Each circuit is ranked in terms of how many cells from it have been
relayed recently, using a time-weighted average.

This patch has been tested this on a private Tor network on PlanetLab,
and gotten improvements of 12-35% in time it takes to fetch a small
web page while there's a simultaneous large data transfer going on
simultaneously.

3807db001d *_free functions now accept NULL
Some *_free functions threw asserts when passed NULL. Now all of them
accept NULL as input and perform no action when called that way.

This gains us consistence for our free functions, and allows some
code simplifications where an explicit null check is no longer necessary.

2aac39a779 Implement DisableAllSwap to avoid putting secret info in page files.
This commit implements a new config option: 'DisableAllSwap'
This option probably only works properly when Tor is started as root.
We added two new functions: tor_mlockall() and tor_set_max_memlock().
tor_mlockall() attempts to mlock() all current and all future memory pages.
For tor_mlockall() to work properly we set the process rlimits for memory to
RLIM_INFINITY (and beyond) inside of tor_set_max_memlock().
We behave differently from mlockall() by only allowing tor_mlockall() to be
called one single time. All other calls will result in a return code of 1.
It is not possible to change DisableAllSwap while running.
A sample configuration item was added to the torrc.complete.in config file.
A new item in the man page for DisableAllSwap was added.
Thanks to Moxie Marlinspike and Chris Palmer for their feedback on this patch.

Please note that we make no guarantees about the quality of your OS and its
mlock/mlockall implementation. It is possible that this will do nothing at all.
It is also possible that you can ulimit the mlock properties of a given user
such that root is not required. This has not been extensively tested and is
unsupported. I have included some comments for possible ways we can handle
this on win32.
