Changes in version 0.2.5.3-alpha - 2014-03-??
Tor 0.2.5.3-alpha includes all the fixes from 0.2.4.21. It contains
- two new anti-DoS features for Tor nodes, resolves a bug that was
- keeping SOCKS5 support for IPv6 from working, fixes several annoying
- usability issues for bridge users, and removes more old
- code for unused directory formats.
+ two new anti-DoS features for Tor nodes, resolves a bug that kept
+ SOCKS5 support for IPv6 from working, fixes several annoying usability
+ issues for bridge users, and removes more old code for unused
+ directory formats.
The Tor 0.2.5.x release series is now in patch-freeze: no feature
patches not already written will be considered for inclusion in
0.2.5.x.
o Major features (server security, DoS-resistance):
- - When we run out of memory and we need to close circuits, also
- consider how much memory is allocated in buffers for streams
- attached to each circuit.
+ - When deciding whether we have run out of memory and we need to
+ close circuits, also consider memory allocated in buffers for
+ streams attached to each circuit.
This change, which extends an anti-DoS feature introduced in
0.2.4.13-alpha and improved in 0.2.4.14-alpha, lets Tor exit nodes
better resist more memory-based DoS attacks than before. Since the
- MaxMemInCellQueues option now applies to all queues, not only cell
- queues, it is now renamed to MaxMemInQueues. This feature fixes

- Avoid hash-flooding denial-of-service attacks by using the secure
SipHash-2-4 hash function for our hashtables. Without this
feature, an attacker could degrade performance of a targeted
client or server by flooding their data structures with a large
- number of data entries all calculated to be stored at the same
- hash table position, thereby slowing down hash table operations.
- With this feature, hash table positions are derived from a
- randomized cryptographic key, and an attacker cannot predict which
- entries will collide. Closes ticket 4900.

- Decrease the lower limit of MaxMemInQueues to 256 MBytes, to
better support Raspberry Pi users. Fixes bug 9686; bugfix on
