Changes in version 0.2.5.4-alpha - 2014-04-25
This release includes several security and performance improvements
for clients and relays, including XXX
for clients and relays, including blacklisting authority signing keys
that were used while susceptible to the OpenSSL "heartbleed" bug,
This release marks end-of-line for Tor 0.2.2.x; those Tor versions
have accumulated many known flaws; everyone should upgrade.

functions previously accounted between 3 and 7% of CPU usage on
some busy relays. Resolves ticket 9841.
- Avoid wasting CPU when extending a circuit over a channel that is
nearly out of circuit IDs. Previously, we would in the worst case
do a linear scan over all possible circuit IDs before deciding
that we had exhausted our possibilities. Now, we try at most 64
random circuit IDs before deciding that we probably won't succeed.
Fix for a possible root cause of ticket #11553.

for a possible root cause of ticket #11553.
o Major features (seccomp2 sandbox, Linux only):
- The seccomp2 sandbox can now run a test network for multiple hours
without crashing. The sandbox is still experimental, and more bugs
will probably turn up. To try it, enable "Sandbox 1" on a Linux
host.

- Strengthen sandbox code: the sandbox can now test the arguments

ticket 11351.
- When the sandbox blocks a system call, it now tries to log a stack
trace before exiting. Resolves ticket 11465.
o Major bugfixes (TLS cipher selection):
- The relay ciphersuite list is now generated automatically based on
uniform criteria, and includes all OpenSSL ciphersuites with
acceptable strength and forward secrecy. Previously, we had
omitted some perfectly fine ciphersuites. Resolves bugs #11513,

do is report a warning, but this may help prevent deeper bugs from
going unnoticed. Closes ticket 8787.
- Fix numerous warnings from the clang "scan-build" static analyzer.
Some of these are programming style issues; some of them are false
positives that indicated awkward code; some are undefined behavior

some are assumptions about API behavior; some are using
sizeof(ptr) when sizeof(*ptr) would be correct; and one or two are
genuine bugs that weren't reachable from the rest of the program.
