Changes in version 0.2.1.3-alpha - 2008-08-03
|
|
|
|
|
o Bootstrapping bugfixes (on 0.2.1.x-alpha):
|
|
|
|
|
- Send a bootstrap problem "warn" event on the first problem if the
|
|
|
|
|
reason is NO_ROUTE (that is, our network is down).
|
|
|
|
|
|
|
|
|
|
o Major features:
|
|
|
|
|
- Implements most of proposal 110: The first K cells to be send
|
|
|
|
|
along a circuit are marked as special "early" cells; only K
|
|
|
|
|
"early" cells will be allowed. Once this code is universal, we
|
|
|
|
|
can block certain kinds of DOS attack by only allowing EXTEND
|
|
|
|
|
commands in these cells.

on the client side when connecting to a hidden service. Bugfix
|
|
|
|
|
on 0.0.6pre1. Found and fixed by Christian Wilms; resolves bug 743.
|
|
|
|
|
- Ensure that two circuits can never exist on the same connection
|
|
|
|
|
with the same circuit ID, even if one is marked for close. This

with the same circuit ID, even if one is marked for close. This

is conceivably a bugfix for bug 779; fixes a bug on 0.1.0.4-rc.
|
|

|
o Minor features:
|
|
|
|
|
- When relays do their initial bandwidth measurement, don't limit
|
|
|
|
|
to just our our entry guards for the test circuits. Otherwise we
|
|
|
|
|
tend to have multiple test circuits going through a single entry
|
|
|
|
|
guard, which makes our bandwidth test less accurate. Fixes part
|
|
|
|
|
of bug 654; patch contributed by Josh Albrecht.

- Add an ExcludeExitNodes option so users can list a set of nodes
|
|
|
|
|
that should be be excluded from the exit node position, but
|
|
|
|
|
allowed elsewhere. Implements proposal 151.

- Allow address patterns (e.g., 255.128.0.0/16) to appear in
|
|
|
|
|
ExcludeNodes and ExcludeExitNodes lists.
|
|
|
|
|
- Change the implementation of ExcludeNodes and ExcludeExitNodes
|
|
|
|
|
to be more efficient. Formerly it was quadratic in the number
|
|
|
|
|
of servers; now it should be linear. Fixes bug 509.

|
|
|
|
|
and n_conn_id_digest fields into a separate structure that's
|
|
|

only needed when the circuit has not yet attached to an n_conn.

|
|
|
|
|
- Stop using __attribute__((nonnull)) with GCC: it can give us useful
|
|
|
|
|
warnings (occasionally), but it can also cause the compiler to
|
|
|
|
|
eliminate error-checking code. Suggested by Peter Gutmann.

|
|
|
don't reschedule publication of the next descriptor. Fixes bug 763.
