5c73da7faa Fix two memory leaks found by Coverity (CIDs 417-418) 
The first happens on an error case when a controller wants an
impossible directory object.  The second happens when we can't write
our fingerprint file.

8bada1ef67 Add missing break statements for Coverity CIDs #406,407. 
The code for these was super-wrong, but will only break things when we
reset an option on a platform where sizeof(time_t) is different from
sizeof(int).

d2b4b49ff0 Reduce log level for someone else sending us weak DH keys. 
See task 1114. The most plausible explanation for someone sending us weak
DH keys is that they experiment with their Tor code or implement a new Tor
client. Usually, we don't care about such events, especially not on warn
level. If we really care about someone not following the Tor protocol, we
can set ProtocolWarnings to 1.

afc76a4e71 Fix two bugs found by Coverity scan. 
One was a simple buffer overrun; the other was a high-speed pointer
collision.  Both were introduced by my microdescs branch.

a007a7c6ba Revise consensus-flavors proposal to better URLs. 
The old flavored consensus URL format made it harder to decode URLs
based on their prefixes, and didn't take into account our "only give
it to me if it's signed by enough authorities" stuff.

0bce0161dd Revise proposal 162: SHA256(x), not SHA256(SHA256(x)) 
The point of doing SHA256 twice is, generally, is to prevent message
extension attacks where an attacker who knows H(A) can calculate
H(A|B).  But for attaching a signature to a document, the attacker
already _knows_ A, so trying to keep them from calculating H(A|B) is
pointless.

3471057486 Implement signatures for microdesc consensuses right. 
This means we need to handle the existence of multiple flavors of signature
in a detached signatures document, generate them correctly, and so on.

3b2fc659a8 Refactor consensus signature storage for multiple digests and flavors. 
This patch introduces a new type called document_signature_t to represent the
signature of a consensus document.  Now, each consensus document can have up
to one document signature per voter per digest algorithm.  Also, each
detached-signatures document can have up to one signature per <voter,
algorithm, flavor>.

80a7a34755 Revise 162's idea of how detached signatures work with flavors 
The original proposal was vague and would have made older Tors reject
detached-signature documents as soon as they saw one with flavors.

c5f7f04aff Allow signed data to include other hashes later. 
Previously, we insisted that a valid signature must be a signature of
the expected digest.  Now we accept anything that starts with the
expected digest.  This lets us include another digest later.

71cdd99dd7 Another event2 evdns fix. 2009-10-13 18:57:25 -04:00
Nick Mathewson
81eee0ecff Fix a crash when using evdns from Libevent 2. 
When we tried to use the deprecated non-threadsafe evdns
interfaces in Libevent 2 without using the also-deprecated
event_init() interface, Libevent 2 would sensibly crash, since it
has no guess where to find the Libevent library.

Here we use the evdns_base_*() functions instead if they're
present, and fake them if they aren't.
