Jack Grigg 6185d8e295 Bump halo2 revision to include `Layouter::assign_table` 2021-07-27 20:54:48 +01:00

therealyingtong 29f185014f merkle: Replace l_plus_1 fixed column with q_decompose selector. 
Previously, l_plus_1 was a non-binary fixed column, used to
1. provide the value of l + 1; and
2. toggle the decomposition gate.

Now, the value is copied in from the global constants column, and
the toggle is handled by a binary q_decompose selector.

Jack Grigg 1dca72a1cc Migrate to latest `halo2` test API 2021-07-19 12:58:05 +01:00
Jack Grigg 15f9d254d9 Migrate to latest `halo2` API 
- `halo2::plonk::{create_proof, verify_proof}` now take instance columns
  as slices of values.
- `halo2::plonk::Permutation` has been replaced by a global permutation,
  to which columns can be added with `ConstraintSystem::enable_equality`.
- The introduction of blinding rows means that various tests now require
  larger circuit parameters.

therealyingtong 5ae9890913 mul::overflow.rs: Overflow check in variable-base scalar mul 
Simplify the canonicity check for variable-base scalar multiplication,
by range-checking the low 130 bits rather than the low 127 bits.

Jack Grigg 5759d66470 Use patches for halo2 and zcash_note_encryption dependencies 
While these two are in flux, it's hard to keep these revisions consistent
(e.g. https://github.com/zcash/zcash/pull/5217 currently depends on two
different versions of zcash_note_encryption). Using patches allows the
downstream users (i.e. zcashd) to define its own set of patches, and keep
everything in sync. This works fine now because we aren't actively making
changes to the public APIs, only additions.

Jack Grigg 3cadb7bb48 Update reddsa dependency 
Earlier in this PR we updated the pasta_crate with a small refactor. The
updated crate also had a separate bugfix to the GroupHash implementation
which caused generators to change. Rust happily pulled in both versions
of pasta_curves, causing the ValueCommit proptests to fail because bsk
was generated with different bases in this crate and reddsa.
