This partially reverts https://github.com/letsencrypt/boulder/pull/8203,
which was landed as commit dea81c7381.
It leaves all of the boulder integration test environment changes in
place, while restoring the DNSAllowLoopbackAddresses config key and its
ability to influence the VA's behavior.
We no longer need a code path to resolve reserved IP addresses during
integration tests.
Move to a public IP for the remaining tests, after #8187 did so for many
of them.
Depends on #8187
Move `IsReservedIP` and its supporting vars from `bdns` to `policy`.
Rewrite `IsReservedIP` to:
* Use `netip` because `netip.Prefix` can be used as a map key, allowing
us to define prefix lists more elegantly. This will enable future work
to import prefix lists from IANA's primary source data.
* Return an error including the reserved network's name.
Refactor `IsReservedIP` tests to be table-based.
Fixes#8040
Plumb the userAgent field, used to set http-01 User-Agent headers, from
va/rva configuration through to where User-Agent headers can be set for
DoH queries. Use integration tests to validate that the User-Agent is
set for http-01 challenges, dns-01 challenges over DoH, and CAA checks
over DoH.
Fixes#7963.
Add an `identifier` field to the `va.PerformValidationRequest` proto, which will soon replace its `dnsName` field.
Accept and prefer the `identifier` field in every VA function that uses this struct. Don't (yet) assume it will be present.
Throughout the VA, accept and handle the IP address identifier type. Handling is similar to DNS names, except that `getAddrs` is not called, and consider that:
- IPs are represented in a different field in the `x509.Certificate` struct.
- IPs must be presented as reverse DNS (`.arpa`) names in SNI for [TLS-ALPN-01 challenge requests](https://datatracker.ietf.org/doc/html/rfc8738#name-tls-with-application-layer-).
- IPv6 addresses are enclosed in square brackets when composing or parsing URLs.
For HTTP-01 challenges, accept redirects to bare IP addresses, which were previously rejected.
Fixes#2706
Part of #7311
Replace DCV and CAA checks (PerformValidation and IsCAAValid) in
va/va.go and va/caa.go with their MPIC compliant counterparts (DoDCV and
DoCAA) in va/vampic.go. Deprecate EnforceMultiCAA and EnforceMPIC and
default code paths as though they are both true. Require that RIR and
Perspective be set for primary and remote VAs.
Fixes#7965Fixes#7819
- Ensure the Perspective and RIR reported by each remoteVA in the
*vapb.ValidationResult returned by VA.PerformValidation, matches the
expected local configuration when that configuration is present.
- Correct "AfriNIC" to "AFRINIC", everywhere.

Previously this was a configuration field.
Ports `maxAllowedFailures()` from `determineMaxAllowedFailures()` in
#7794.
Test updates:
Remove the `maxRemoteFailures` param from `setup` in all VA tests.
Some tests were depending on setting this param directly to provoke
failures.
For example, `TestMultiVAEarlyReturn` previously relied on "zero allowed
failures". Since the number of allowed failures is now 1 for the number
of remote VAs we were testing (2), the VA wasn't returning early with an
error; it was succeeding! To fix that, make sure there are two failures.
Since two failures from two RVAs wouldn't exercise the right situation,
add a third RVA, so we get two failures from three RVAs.
Similarly, TestMultiCAARechecking had several test cases that omitted
this field, effectively setting it to zero allowed failures. I updated
the "1 RVA failure" test case to expect overall success and added a "2
RVA failures" test case to expect overall failure (we previously
expected overall failure from a single RVA failing).
In TestMultiVA I had to change a test for `len(lines) != 1` to
`len(lines) == 0`, because with more backends we were now logging more
errors, and finding e.g. `len(lines)` to be 2.
- Add `Perspective` and `RIR` fields to the remote-va configuration
- Configure RVA ValidationAuthorityImpl instances with the contents of
the JSON configuration
- Configure VA ValidationAuthorityImpl instances with the constant
`va.PrimaryPerspective`
- Log `Perspective` for non-Primary Perspectives, per the MPIC
requirements in section 5.4.1 (2) vii of the BRs. Also log the RIR for
posterity.
- Introduce `ValidationResult` RPC fields `Perspective` and `Rir`, which
are not currently used but will be required for corroboration in #7616

* Adds a `VerifyGRPCClientCertIfGiven` boolean to the `remoteva` config
that cause the RVA server to use the less strict
`tls.VerifyClientCertIfGiven` for use with an Amazon Web Services
Application Load Balancer (ALB) between the `boulder-va` and `remoteva`.

* Adds a new `remoteva` binary that takes a distinct configuration from
the existing `boulder-va`
* Removed the `boulder-remoteva` name registration from `boulder-va`.
* Existing users of `boulder-remoteva` must either
1. laterally migrate to `boulder-va` which uses that same config, or
2. switch to using `remoteva` with a new config.
