One format we receive key compromise reports is as a CSR file. For
example, from https://pwnedkeys.com/revokinator
This allows the admin command to block a key from a CSR directly,
instead of needing to validate it manually and get the SPKI or key from
it.
I've added a flag (default true) to check the signature on the CSR, in
case we ever decide we want to block a key from a CSR with a bad
signature for whatever reason.
Update the version of protoc-gen-go-grpc that we use to generate Go gRPC
code from our proto files, and update the versions of other gRPC tools
and libraries that we use to match. Turn on the new
`use_generic_streams` code generation flag to change how
protoc-gen-go-grpc generates implementations of our streaming methods,
from creating a wholly independent implementation for every stream to
using shared generic implementations.
Take advantage of this code-sharing to remove our SA "wrapper" methods,
now that they have truly the same signature as the SARO methods which
they wrap. Also remove all references to the old-style stream names
(e.g. foopb.FooService_BarMethodClient) and replace them with the new
underlying generic names, for the sake of consistency. Finally, also
remove a few custom stream test mocks, replacing them with the generic
mocks.ServerStreamClient.
Note that this PR does not change the names in //mocks/sa.go, to avoid
conflicts with work happening in the pursuit of
https://github.com/letsencrypt/boulder/issues/7476. Note also that this
PR updates the version of protoc-gen-go-grpc that we use to a specific
commit. This is because, although a new release of grpc-go itself has
been cut, the codegen binary is a separate Go module with its own
releases, and it hasn't had a new release cut yet. Tracking for that is
in https://github.com/grpc/grpc-go/issues/7030.
Replace "mocks.StorageAuthority" with "sapb.StorageAuthorityClient" in
our test mocks. The improves them by removing implementations of the
methods the tests don't actually need, instead of inheriting lots of
extraneous methods from the huge and cumbersome mocks.StorageAuthority.
This reduces our usage of mocks.StorageAuthority to only the WFE tests
(which create one in the frequently-used setup() function), which will
make refactoring those mocks in the pursuit of
https://github.com/letsencrypt/boulder/issues/7476 much easier.

Add a new input method flag to `admin block-key` which processes a file
containing one hexadecimal-encoded SPKI hash on each line. To facilitate
this, restructure the block-key subcommand's execution to more closely
resemble the revoke-cert subcommand, with a parallelism flag and the
ability to run many workers at the same time.

Use two existing SA methods, KeyBlocked and GetSerialsByKey, to replace
the direct database access previously used by the blockSPKIHash method.
This is less efficient than before -- it now streams the whole set of
affected serials rather than just counting them -- but doing so prevents
us from needing an additional SA method just for counting.
Also update the default mock StorageAuthority and
StorageAuthorityReadOnly provided by the mocks package to return actual
stream objects (which stream zero results) instead of nil, so that tests
can attempt to read from the resulting stream without getting a nil
pointer exception.

Create a new administration tool "bin/admin" as a successor to and
replacement of "admin-revoker".
This new tool supports all the same fundamental capabilities as the old
admin-revoker, including:
- Revoking by serial, by batch of serials, by incident table, and by
private key
- Blocking a key to let bad-key-revoker take care of revocation
- Clearing email addresses from all accounts that use them
Improvements over the old admin-revoker include:
- All commands run in "dry-run" mode by default, to prevent accidental
executions
- All revocation mechanisms allow setting the revocation reason,
skipping blocking the key, indicating that the certificate is malformed,
and controlling the number of parallel workers conducting revocation
- All revocation mechanisms do not parse the cert in question, leaving
that to the RA
- Autogenerated usage information for all subcommands
- A much more modular structure to simplify adding more capabilities in
the future
- Significantly simplified tests with smaller mocks
The new tool has analogues of all of admin-revokers unit tests, and all
integration tests have been updated to use the new tool instead. A
future PR will remove admin-revoker, once we're sure SRE has had time to
update all of their playbooks.
