Marc Brinkmann eafa77d5fc OsRng / external RNG Refactoring (#357)
* Use `OsRng` in place of `thread_rng`.

This changes the defaults of any builder by instantiating an `OsRng` instead of
a `thread_rng`, the former being much more secure than the latter.

Additionally, all the unit tests that still instantiate RNGs manually used `OsRng`s
as well; while there is no actual need for this level of security in tests, the performance overhead is very small and random number generation complexity has such a small impact on these tests that the convenience of being able to ban `thread_rng` from the codebase altogether, setting a good example and avoid issues when refactoring later greatly outweigh the negatives.

* Instead of storing random number generators in the various consensus algorithm instances, pass them in from the outside whenever they are needed.

This changes a large amount of interfaces (and in this commit is only partially done, since `DistAlgorithm` needs to be fundamentally altered as well.

It also obsoletes parts of the `util` module.

* Added an `R: Rng` type parameter to both methods of `DistAlgorithm`, forcing callers to pass in their own Rngs.

* Fixed documentation grammar and spelling in some of the altered interfaces due to RNG refactoring.

* Move `rng` argument to the end of the argument for most functions.

Also includes a reformatting due to Rust 1.30.

* Updated tests, accomodate `rng`-API changes.

* Fixed remaining compilation issues with new RNG code.

* Fix illegal `self` import outside curly braces.

* Cleaned up comments and fixed broken definition of `broadcast_input`.

* Updated existing test cases to properly work with static dispatch randomness.

* Do not use boxed `Rng`s for key generation in test networks.

* Use the passed-in `Rng` in `ReorderingAdversary`, instead of storing a boxed one.

* Fixed clippy lints after refactoring.

* Removed some no-longer necessary manual `fmt::Debug` implementations in test framework.

* Use `OsRng` even in tests in `binary_agreement_mitm`.

* Use a proper deterministic RNG in tests `binary_agreement_mitm`.

* Refactor `examples/simulation.rs` by not using `ThreadRng`, passing generic `Rng` parameters throughout and using a type alias instead of a newtype as the `Transaction`.

* Remove `thread_rng` use from `examples/node.rs`.

* Explicitly construct `InternalContrib` in `DynamicHoneyBadger::propose`.

* Fixed typo in description of `DistAlgorithm` trait.

Better proptest persistence through deterministic randomness. (#248)
* Add support for RNG instantiation in proptests.

* Use `proptest` module strategy to create the rng for `net_dynamic_honey_badger`.

* Use seed generation instead of RNG instantiation in tests.

* Remove fixed RNG in `generate_map`.

* `VirtualNet` now supports setting the random generator through the builder.

* Add missing `time_limit` field to `::std::fmt::Debug` trait implementation on `NetBuilder`.

* Pass an instantiated random number generator through `NewNodeInfo` as a convenience.

* Make the random number generator of `DynamicHoneyBadgerBuilder` configurable, at the cost of now requiring mutability to call `build_first_node()`.

* Ensure RNGs are derive from passed in seed in `net_dynamic_hb` tests.

* Correct inappropriate use of `random::Random` instead of `Rng::gen` to generate dependent values in `binary_agreement`.

The original implementation used `rand::random()`, which will always use the `thread_rng`, ignoring the fact that an RNG has actually been passed in.

* Do not use `OsRng` but passed in RNG instead.

* Use reference/non-reference passing of rngs more in line with the `rand` crates conventions.

* Document `rng` field on `DynamicHoneyBadger`.

* Make `SyncKeyGen` work with the extend (`encrypt_with_rng`) API of `threshold_crypto`.

* Use passed-in random number generator in `HoneyBadger`.

* Create `SubRng` crate in new `util` module to replace `create_rng()`.

* Use an RNG seeded from the configure RNG when reinitializing `DynamicHoneyBadger`.

* Use the correct branch of `threshold_crypto` with support for passing RNGs.

Andreas Fackler 984bb49fdc Accept more types in threshold crypto API.
This removes some unnecessary allocation and conversion by accepting
more primitive types and references as the index in threshold decryption
and signing, and as the argument to a polynomial.

Merge branch 'master' into vk-api-refactor66 2018-07-13 13:53:21 +01:00
Marc Brinkmann 5336fbe707 Added `RandomAdversary` and the necessary auxiliary functions.
Random adversaries are created for `broadcast` and `honey_badger`.  Random value generation was added for all type-dependencies of these algorithms, causing the `Rand` trait to be implement for a large portion of the codebase.

Additionally, `MessageWithSender` turned into an actual struct, making it much easier to handle. Tuple-like construction is still available through `MessageWithSender::new()`.

which will be necessary for use with Parity.

Andreas Fackler c1b4381753 Separate queue from Honey Badger.
This makes Honey Badger a bit more complicated but a lot more flexible:
It is now unaware of transactions and basically just runs one Subset
instance per epoch.

That way, users can use any kind of external queue, control throttling
and prioritization.
