- Re-issue all gRPC credentials for `<service-name>.service.consul`
Part of #6111
Enable the "unparam" linter, which checks for unused function
parameters, unused function return values, and parameters and
return values that always have the same value every time they
are used.
In addition, fix many instances where the unparam linter complains
about our existing codebase. Remove error return values from a
number of functions that never return an error, remove or use
context and test parameters that were previously unused, and
simplify a number of (mostly test-only) functions that always take the
same value for their parameter. Most notably, remove the ability to
customize the RSA Public Exponent from the ceremony tooling,
since it should always be 65537 anyway.
Fixes#6104
## CI: restore load-generator run.
This restores running the `load-generator` during CI to make sure it doesn't bitrot. It was previously removed while we debugged the VA getting jammed up and not cleanly shutting down.
Since the global `pebble-challtestsrv` and the `load-generator`'s internal chall test srv will conflict this requires moving the `load-generator` run to the end of integration tests and updating `startservers.py` to allow the load gen integration test code to stop the `pebble-challtestsrv` before starting the `load-generator`.
The `load-generator` and associated config are updated to allow specifying bind addresses for the DNS interface of the internal challtestsrv. Multiple addresses are supported so that the `load-generator`'s chall test srv can listen on port DNS ports Boulder is configured to use. The `load-generator` config now accepts a `fakeDNS` parameter that can be used to specify the default IPv4 address returned by the `load-generator`'s DNS server for A queries.
## load-generator: support different challenges/strategies.
Updates the load-generator to support HTTP-01, DNS-01, and TLS-ALPN-01 challenge response servers. A new challenge selection configuration parameter (`ChallengeStrategy`) can be set to `"http-01"`, `"dns-01"`, or `"tls-alpn-01"` to solve only challenges of that type. Using `"random"` will let the load-generator choose a challenge type randomly.
Resolves https://github.com/letsencrypt/boulder/issues/3900
Removing hard-coded paths and using the server directory to bootstrap endpoint URLs improves RFC 8555 compatibility.
This branch also updates the `github.com/letsencrypt/challtestsrv` vendored dep to the latest release. There are no upstream unit tests to run.
Updates https://github.com/letsencrypt/boulder/issues/4086 - there are still a few Pebble compatibility issues to work out. I started on what became a near total rewrite of the load-generator and decided it was best to pull out some smaller PRs and re-evaluate. I'm optimistic that stashing little bits of a Go testing/boulder focused ACME client in `test/load-generator` will one day help https://github.com/letsencrypt/boulder/issues/4127
We don't intend to load test the legacy WFE implementation in the future
and if we need to we can always revive this code from git. Removing it
will make refactoring the ACME v2 code to be closer to RFC 8555 easier.
load generator: send correct ACMEv2 Content-Type on POST.
This PR updates the Boulder load-generator to send the correct ACMEv2 Content-Type header when POSTing the ACME server. This is required for ACMEv2 and without it all POST requests to the WFE2 running a test/config-next configuration result in malformed 400 errors. While only required by ACMEv2 this commit sends it for ACMEv1 requests as well. No harm no foul.
integration tests: allow running just the load generator.
Prior to this PR an omission in an if statement in integration-test.py meant that you couldn't invoke test/integration-test.py with just the --load argument to only run the load generator. This commit updates the if to allow this use case.
This commit adds short 15s runs of the load generator against the V1 and
V2 APIs during the three integration test runs (v1 config, v1
config-next, and v2). 15s was selected because 30s caused too much
output and the build log to be truncated.
Presently the latency output is *not* being checked for errors. This was
too flaky in practice.
A fix for a race condition in the load-generator code itself related to
HTTP status code tracking is included in this commit.
The pending authz rate limit also needed to be adjusted to keep the
load-generator from failing requests after hitting 429s.
