| * | Fix a warning when building with --disable-curve25519•••It appears that the code for 7291 gave an unused-value warning when
built with --disable-curve25519.

| | * | Use a TAILQ, not a singly-linked queue, for the onion queue.•••This makes removing items from the middle of the queue into an O(1)
operation, which could prove important as we let onionqueues grow
longer.
Doing this actually makes the code slightly smaller, too.
| Nick Mathewson | 2013-01-03 |
| | * | Eliminate MaxOnionsPending; replace it with MaxOnionQueueDelay•••The right way to set "MaxOnionsPending" was to adjust it until the
processing delay was appropriate. So instead, let's measure how long
it takes to process onionskins (sampling them once we have a big
number), and then limit the queue based on its expected time to
finish.
This change is extra-necessary for ntor, since there is no longer a
reasonable way to set MaxOnionsPending without knowing what mix of
onionskins you'll get.
This patch also reserves 1/3 of the onionskin spots for ntor
handshakes, on the theory that TAP handshakes shouldn't be allowed to
starve their speedier cousins. We can change this later if need be.
Resolves 7291.

response is now a created_cell_t. Several of the things that call or
get called by this chain of logic now take create_cell_t or
created_cell_t too.
Since all cpuworkers are forked or spawned by Tor, they don't need a
stable wire protocol, so we can just send structs. This saves us some
insanity, and helps p

| * | Code to parse and format CREATE{,2,_FAST} cells and their allies•••As elsewhere, it makes sense when adding or extending a cell type to
actually make the code to parse it into a separate tested function.
This commit doesn't actually make anything use these new functions;
that's for a later commit.

| * | Massive refactoring of the various handshake types•••The three handshake types are now accessed from a unified interface;
their state is abstracted from the rest of the cpath state, and so on.
| Nick Mathewson | 2013-01-03 |
| * | Split onion.[ch] into onion{,_fast,_tap}.[ch]•••I'm going to want a generic "onionskin" type and set of wrappers, and
for that, it will be helpful to isolate the different circuit creation
handshakes. Now the original handshake is in onion_tap.[ch], the
CREATE_FAST handshake is in onion_fast.[ch], and onion.[ch] now
handles the onion queue.
This commit does nothing but move code and adjust header files.
| Nick Mathewson | 2013-01-02 |
| * | Implement HKDF from RFC5869•••This is a customizable extract-and-expand HMAC-KDF for deriving keys.
It derives from RFC5869, which derives its rationale from Krawczyk,
H., "Cryptographic Extraction and Key Derivation: The HKDF Scheme",
Proceedings of CRYPTO 2010, 2010, <http://eprint.iacr.org/2010/264>.
I'm also renaming the existing KDF, now that Tor has two of them.
This is the key derivation scheme specified in ntor.
There are also unit tests.

| | * | Add and use and unlikely-to-be-eliminated memwipe()•••Apparently some compilers like to eliminate memset() operations on
data that's about to go out-of-scope. I've gone with the safest
possible replacement, which might be a bit slow. I don't think this
is critical path in any way that will affect performance, but if it
is, we can work on that in 0.2.4.
Fixes bug 7352.

Second, add in a few grouping @{ and @} entries in order to get some

| | * | Hand-conversion and audit phase of memcmp transition•••Here I looked at the results of the automated conversion and cleaned
them up as follows:
If there was a tor_memcmp or tor_memeq that was in fact "safe"[*] I
changed it to a fast_memcmp or fast_memeq.
Otherwise if there was a tor_memcmp that could turn into a
tor_memneq or tor_memeq, I converted it.
This wants close attention.
[*] I'm erring on the side of caution here, and leaving some things
as tor_memcmp that could in my opinion use the data-dependent
fast_memcmp variant.

level. If we really care about someone not following the Tor protocol, we
can set ProtocolWarnings to 1.
