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>.

e1ddee8bbe Code to generate, store, and parse microdescriptors and consensuses. 
The consensus documents are not signed properly, not served, and not
exchanged yet.

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.

The test suite need the test.h file to build. Add it to
noinst_HEADERS in the Makefile.am so it gets included
in the tarball that make dist produces.

2f760c5461 Fix testsuite call. 
tinytest_main() returns 0 on success, -1 on errors and 1 on test
failures.  So test.c should check on !=0 instead of <0.

5a6575c2d4 Don't set unreachable from dirvote unless we've been running a while. 
This is a possible fix for bug 1023, where if we vote (or make a v2
consensus networkstatus) right after we come online, we can call
rep_hist_note_router_unreachable() on every router we haven't connected
to yet, and thereby make all their uptime values reset.

e84dc32cb8 correct the spec for the stream_bw event. 
"neonomad" pointed out on or-talk that the order is opposite from the
intuitive order. explain why. we chose to fix the spec rather than the
code because there are controllers like torflow that already expect
the current behavior.

18689317e4 Tweak an assert that shouldn't fire either way. 
There were however other places where we used to call this
function that might have caused this to fire. Better

ec05e64a68 Tweak values for when to discard all of our history. 
This seems to be happening to me a lot on a garbage DSL line.
We may need to come up with 2 threshholds: a high short onehop
count and a lower longer count.
