Remove the .Error() method from probs.ProblemDetails, so that it can no
longer be returned from functions which return an error. Update various
call sites to use the .String() method to get a textual representation
of the problem instead. Simplify ProblemDetailsForError to not
special-case and pass-through ProblemDetails, since they are no longer a
valid input to that function.
This reduces instances of "boxed nil" bugs, and paves the way for all of
the WFE methods to be refactored to simply return errors instead of
writing them directly into the response object.
Part of https://github.com/letsencrypt/boulder/issues/4980
Add `identifier` fields, which will soon replace the `dnsName` fields,
to:
- `corepb.Authorization`
- `corepb.Order`
- `rapb.NewOrderRequest`
- `sapb.CountFQDNSetsRequest`
- `sapb.CountInvalidAuthorizationsRequest`
- `sapb.FQDNSetExistsRequest`
- `sapb.GetAuthorizationsRequest`
- `sapb.GetOrderForNamesRequest`
- `sapb.GetValidAuthorizationsRequest`
- `sapb.NewOrderRequest`
Populate these `identifier` fields in every function that creates
instances of these structs.
Use these `identifier` fields instead of `dnsName` fields (at least
preferentially) in every function that uses these structs. When crossing
component boundaries, don't assume they'll be present, for
deployability's sake.
Deployability note: Mismatched `cert-checker` and `sa` versions will be
incompatible because of a type change in the arguments to
`sa.SelectAuthzsMatchingIssuance`.
Part of #7311
Update the SA to re-query the database for the updated account after
deactivating it, and return this to the RA. Update the RA to pass this
value through to the WFE. Update the WFE to return this value, rather
than locally modifying the pre-deactivation account object, if it gets
one (for deployability).
Also remove the RA's requirement that the request object specify its
current status so that the request can be trimmed down to just an ID.
This proto change is backwards-compatible because the new
DeactivateRegistrationRequest's registrationID field has the same type
(int64) and field number (1) as corepb.Registration's id field.
Part of https://github.com/letsencrypt/boulder/issues/5554
Remove some RA tests that were checking for errors specific to the split
issuance flow. Make one of the tests test GetSCTs directly, which makes
for a much nicer test!
Add MaxNames to the set of things that can be configured on a
per-profile basis. Remove all references to the RA's global maxNames,
replacing them with reference's to the current profile's maxNames. Add
code to the RA's main() to copy a globally-configured MaxNames into each
profile, for deployability.
Also remove any understanding of MaxNames from the WFE, as it is
redundant with the RA and is not configured in staging or prod. Instead,
hardcode the upper limit of 100 into the ratelimit package itself.
Fixes https://github.com/letsencrypt/boulder/issues/7993
Add a new RPC to the CA: `IssueCertificate` covers issuance of both the
precertificate and the final certificate. In between, it calls out to
the RA's new method `GetSCTs`.
The RA calls the new `CA.IssueCertificate` if the `UnsplitIssuance`
feature flag is true.
The RA had a metric that counted certificates by profile name and hash.
Since the RA doesn't receive a profile hash in the new flow, simply
record the total number of issuances.
Fixes https://github.com/letsencrypt/boulder/issues/7983
Remove the RA's deprecated top-level config keys which used to control
order and authz lifetimes. Make the new profile-based config keys which
replaced them required.
Since configuring a profile and default profile name is now mandatory,
always supply a profile name to the CA when requesting issuance.
Fixes https://github.com/letsencrypt/boulder/issues/7986
If validation profiles haven't been explicitly configured, use the
default profile for all incoming requests regardless of which profile
they specify.
Fixes https://github.com/letsencrypt/boulder/issues/7605
Add three new fields to the ra.ValidationProfile structure, representing
the profile's pending authorization lifetime (used to assign an
expiration when a new authz is created), valid authorization lifetime
(used to assign an expiration when an authz is successfully validated),
and order lifetime (used to assign an expiration when a new order is
created). Remove the prior top-level fields which controlled these
values across all orders.
Add a "defaultProfileName" field to the RA as well, to facilitate
looking up a default set of lifetimes when the order doesn't specify a
profile. If this default name is explicitly configured, always provide
it to the CA when requesting issuance, so we don't have to duplicate the
default between the two services.
Modify the RA's config struct in a corresponding way: add three new
fields to the ValidationProfiles structure, and deprecate the three old
top-level fields. Also upgrade the ra.NewValidationProfile constructor
to handle these new fields, including doing validation on their values.
Fixes https://github.com/letsencrypt/boulder/issues/7605
In the RA, inspect the profile of all authorizations returned when
looking for authz reuse, and refuse to reuse any whose profile doesn't
match the requested profile of the current NewOrder request.
Fixes https://github.com/letsencrypt/boulder/issues/7949
Improve the test of the `ra.validationProfiles` field by providing a
constructed `map[string]*ValidationProfile` instead of constructing one
inside the test. Much like how this data is provided, or `nil`, in calls
to `ra.NewRegistrationAuthorityImpl()`.
Add support in the RA for an allow list of accounts permitted to request
certificates containing the OCSP Must-Staple extension. If no allow list
is configured, all accounts are permitted. When a list is provided,
Finalize requests with Must-Staple are rejected unless the account is on
the list, and metrics are updated to track allowed and denied requests.
Fixes#7914
In RA.RevokedCertificate, if the certificate being revoked has a
crlDistributionPoints extension, parse the URL and pass the appropriate
shard to the SA.
This required some changes to the `admin` tool. When a malformed
certificate is revoked, we don't have a parsed copy of the certificate
to extract a CRL URL from. So, specifically when a malformed certificate
is being revoked, allow specifying a CRL shard. Because different
certificates will have different shards, require one-at-a-time
revocation for malformed certificates.
To support that refactoring, move the serial-cleaning functionality
earlier in the `admin` tool's flow.
Also, split out one of the cases handled by the `revokeCertificate`
helper in the RA. For admin malformed revocations, we need to accept a
human-specified ShardIdx, so call the SA directly in that case (and skip
stat increment since admin revocations aren't useful for metrics). This
allows `revokeCertificate` to be a more helpful helper, by extracting
serial, issuer ID, and CRL shard automatically from an
`*x509.Certificate`.
Note: we don't yet issue certificates with the crlDistributionPoints
extension, so this code will not be active until we start doing so.

This is the final stage of #5554: removing the old, combined
`UpdateRegistration` flow, which has been replaced by
`UpdateRegistrationContact` and `UpdateRegistrationKey`. Those new
functions have their own tests.
The RA's `UpdateRegistration` function no longer has any callers (as of
#7827's deployment), so it is safely deployable to remove it from the SA
too, and its request from gRPC.

Remove code using `certificatesPerName` & `newOrdersRL` tables.
Deprecate `DisableLegacyLimitWrites` & `UseKvLimitsForNewOrder` flags.
Remove legacy `ratelimit` package.
Delete these RA test cases:
- `TestAuthzFailedRateLimitingNewOrder` (rl:
`FailedAuthorizationsPerDomainPerAccount`)
- `TestCheckCertificatesPerNameLimit` (rl: `CertificatesPerDomain`)
- `TestCheckExactCertificateLimit` (rl: `CertificatesPerFQDNSet`)
- `TestExactPublicSuffixCertLimit` (rl: `CertificatesPerDomain`)
Rate limits in NewOrder are now enforced by the WFE, starting here:
5a9b4c4b18/wfe2/wfe.go (L781)
We collect a batch of transactions to check limits, check them all at
once, go through and find which one(s) failed, and serve the failure
with the Retry-After that's furthest in the future. All this code
doesn't really need to be tested again; what needs to be tested is that
we're returning the correct failure. That code is
`NewOrderLimitTransactions`, and the `ratelimits` package's tests cover
this.
The public suffix handling behavior is tested by
`TestFQDNsToETLDsPlusOne`:
5a9b4c4b18/ratelimits/utilities_test.go (L9)
Some other RA rate limit tests were deleted earlier, in #7869.
Part of #7671.
And in the RA, log the notBefore of the previous issuance.
To make this happen, I had to hoist the "check for previous certificate"
up a level into `issueCertificateOuter`. That meant I also had to hoist
the "split off a WithoutCancel context" logic all the way up to
`FinalizeOrder`.
Add a new `ratelimits.NewTransactionBuilderWithLimits` constructor which
takes pre-populated rate limit data, instead of filenames for reading it
off disk.
Use this new constructor to change rate limits during RA tests, instead
of using extra `testdata` files.
Fix ARI renewals' exception from rate limits: consider `isARIRenewal` as
part of the `isRenewal` arg to `checkNewOrderLimits`.
Remove obsolete RA tests for rate limits that are now only checked in
the WFE.
Update remaining new order rate limit tests from deprecated `ratelimit`s
to new Redis `ratelimits`.
Today, we have VA.PerformValidation, a method called by the RA at
challenge time to perform DCV and check CAA. We also have VA.IsCAAValid,
a method invoked by the RA at finalize time when a CAA re-check is
necessary. Both of these methods can be executed on remote VA
perspectives by calling the generic VA.performRemoteValidation.
This change splits VA.PerformValidation into VA.DoDCV and VA.DoCAA,
which are both called on remote VA perspectives by calling the generic
VA.doRemoteOperation. VA.DoDCV, VA.DoCAA, and VA.doRemoteOperation
fulfill the requirements of SC-067 V3: Require Multi-Perspective
Issuance Corroboration by:
- Requiring at least three distinct perspectives, as outlined in the
"Phased Implementation Timeline" in BRs section 3.2.2.9 ("Effective
March 15, 2025").
- Ensuring that the number of non-corroborating (failing) perspectives
remains below the threshold defined by the "Table: Quorum Requirements"
in BRs section 3.2.2.9.
- Ensuring that corroborating (passing) perspectives reside in at least
2 distinct Regional Internet Registries (RIRs) per the "Phased
Implementation Timeline" in BRs section 3.2.2.9 ("Effective March 15,
2026").
- Including an MPIC summary consisting of: passing perspectives, failing
perspectives, passing RIRs, and a quorum met for issuance (e.g., 2/3 or
3/3) in each validation audit log event, per BRs Section 5.4.1,
Requirement 2.8.
When the new SeparateDCVAndCAAChecks feature flag is enabled on the RA,
calls to VA.IsCAAValid (during finalization) and VA.PerformValidation
(during challenge) are replaced with calls to VA.DoCAA and a sequence of
VA.DoDCV followed by VA.DoCAA, respectively.

Pending authz reuse is a nice-to-have feature because it allows us to
create fewer rows in the authz database table when creating new orders.
However, stats show that less than 2% of authorizations that we attach
to new orders are reused pending authzs. And as we move towards using a
more streamlined database schema to store our orders, authorizations,
and validation attempts, disabling pending authz reuse will greatly
simplify our database schema and code.
CPS Compliance Review: our CPS does not speak to whether or not we reuse
pending authorizations for new orders.
IN-10859 tracks enabling this flag in prod

Greatly simplify the two RA unit tests covering failed validations and
account+identifier pausing. Most importantly, directly manipulate the
ratelimit backing store during test setup, to avoid having to "perform"
extra validations.
Fixes https://github.com/letsencrypt/boulder/issues/7812
The purpose of these RA and WFE unit tests is to test how they deal with
certain rate limit conditions, not to test talking to an actual redis
instance. Streamline the tests by having them talk to an in-memory rate
limits store, rather than a redis-backed one.
- Make performRemoteValidation a more generic function that returns a
new remoteResult interface
- Modify the return value of IsCAAValid and PerformValidation to satisfy
the remoteResult interface
- Include compile time checks and tests that pass an arbitrary operation
When a client deactivates a pending authorization, count that towards
their FailedAuthorizationsPerDomainPerAccount and
FailedAuthorizationsForPausingPerDomainPerAccount rate limits. This
should help curb the few clients which constantly create new orders and
authzs, deactivate those pending authzs preventing reuse of them or
their orders, and then rinse and repeat.
Fixes https://github.com/letsencrypt/boulder/issues/7834
TestPerformValidation_FailedThenSuccessfulValidationResetsPauseIdentifiersRatelimit
checks for a bucket being empty after a reset. However, that bucket is
based on an account ID that is shared across multiple test cases.
Instead, use a unique account and domain for this test.
Fixes#7812
- Added a new key-value ratelimit
`FailedAuthorizationsForPausingPerDomainPerAccount` which is incremented
each time a client fails a validation.
- As long as capacity exists in the bucket, a successful validation
attempt will reset the bucket back to full capacity.
- Upon exhausting bucket capacity, the RA will send a gRPC to the SA to
pause the `account:identifier`. Further validation attempts will be
rejected by the [WFE](https://github.com/letsencrypt/boulder/pull/7599).
- Added a new feature flag, `AutomaticallyPauseZombieClients`, which
enables automatic pausing of zombie clients in the RA.
- Added a new RA metric `paused_pairs{"paused":[bool],
"repaused":[bool], "grace":[bool]}` to monitor use of this new
functionality.
- Updated `ra_test.go` `initAuthorities` to allow accessing the
`*ratelimits.RedisSource` for checking that the new ratelimit functions
as intended.

Introduce separate UpdateRegistrationContact & UpdateRegistrationKey
methods in RA & SA
Clear contact field during DeactivateRegistration
Part of #7716
Part of #5554
Clean up how we handle identifiers throughout the Boulder codebase by
- moving the Identifier protobuf message definition from sa.proto to
core.proto;
- adding support for IP identifier to the "identifier" package;
- renaming the "identifier" package's exported names to be clearer; and
- ensuring we use the identifier package's helper functions everywhere
we can.
This will make future work to actually respect identifier types (such as
in Authorization and Order protobuf messages) simpler and easier to
review.
Part of https://github.com/letsencrypt/boulder/issues/7311
When creating an authorization, populate it with all challenges
appropriate for that identifier, regardless of whether those challenge
types are currently "enabled" in the config. This ensures that
authorizations created during a incident for which we can temporarily
disabled a single challenge type can still be validated via that
challenge type after the incident is over.
Also, when finalizing an order, check that the challenge type used to
validation each authorization is not currently disabled. This ensures
that, if we temporarily disable a single challenge due to an incident,
we don't issue any more certificates using authorizations which were
fulfilled using that disabled challenge.
Note that standard rolling deployment of this change is not safe if any
challenges are disabled at the same time, due to the possibility of an
updated RA not filtering a challenge when writing it to the database,
and then a non-updated RA not filtering it when reading from the
database. But if all challenges are enabled then this change is safe for
normal deploy.

Find all gRPC fields which represent DNS Names -- sometimes called
"identifier", "hostname", "domain", "identifierValue", or other things
-- and unify their naming. This naming makes it very clear that these
values are strings which may be included in the SAN extension of a
certificate with type dnsName.
As we move towards issuing IP Address certificates, all of these fields
will need to be replaced by fields which carry both an identifier type
and value, not just a single name. This unified naming makes it very
clear which messages and methods need to be updated to support
non-dnsName identifiers.

This compile error was introduced by the combination of
https://github.com/letsencrypt/boulder/pull/7650 (which changed the type
of mockSAWithAuthzs.authzs) and
https://github.com/letsencrypt/boulder/pull/7652 (which introduced a new
usage of mockSAWithAuthzs.authzs). Because the latter PR introduced a
new usage, rather than modifying an existing usage, it didn't create a
merge conflict and wasn't caught by GitHub's mergeability checker.
Add a new "GetAuthorization" method to the RA. This method is very
similar to the SA's existing "GetAuthorization2" method, except that it
also uses the RA's built-in Policy Authority to filter out any
challenges which are currently disabled.
In a follow-up change, the WFE will be updated to use this method when
retrieving authorizations and challenges for display, so that we can
ensure disabled challenges are not presented to ACME clients.

Replace all of Boulder's usage of the Go stdlib "math/rand" package with
the newer "math/rand/v2" package which first became available in go1.22.
This package has an improved API and faster performance across the
board.
See https://go.dev/blog/randv2 and https://go.dev/blog/chacha8rand for
details.
This is a followup to https://github.com/letsencrypt/boulder/pull/7646,
updating two other RA methods (RevokeCertByApplicant and NewOrder) which
call different SA methods (GetValidAuthorizations2 and
GetAuthorizations2) but receive the same return type
(sapb.Authorizations) from the SA to use that type's new field.
Simplify SA.GetValidOrderAuthorizations2 so that it no longer conditions
the query on the status, expiry, or registration ID of the authorization
rows. This gives the query much better performance, because it no longer
tries to use an overly-large index, and fall back to large row-scans
when the query planner decides the index is too large.
While we're here, also improve the return type of
GetValidOrderAuthorizations2, so that instead of returning a map of
names to authorizations, it simply returns a list of authzs. This both
reduces the size of the gRPC message (once the old map is fully
removed), and improves its correctness because we cannot count on names
to be unique across multiple identifier types.
Finally, improve the RA code which calls SA.GetValidOrderAuthorizations2
to handle this improved return type, to make fewer assumptions about
identifier types, and to separate static authorization-checking from CAA
rechecking.
Fixes https://github.com/letsencrypt/boulder/issues/7645
Within the NewOrderAndAuthzsRequest, replace the corepb.Authorization
field with a new sapb.NewAuthzRequest message. This message has all of
the same field types and numbers, and the RA still populates all of
these fields when constructing a request, for backwards compatibility.
But it also has new fields (an Identifier carrying both type and value,
a list of challenge types, and a challenge token) which the RA
preferentially consumes if present.
This causes the content of our NewOrderAndAuthzsRequest to more closely
match the content that will be created at the database layer. Although
this may seem like a step backwards in terms of abstraction, it is also
a step forwards in terms of both efficiency (not having to transmit
multiple nearly-identical challenge objects) and correctness (being
guaranteed that the token is actually identical across all challenges).
After this change is deployed, it will be followed by a change which
removes the old fields from the NewAuthzRequest message, to realize the
efficiency gains.

Have the RA's UnpauseAccount gRPC method forward the requested account
ID to the SA's corresponding method, and in turn forward the SA's count
of unpaused identifiers back to the caller in the response.
Changing the response message from emptypb.Empty to a new
rapb.UnpauseAccountResponse is safe, because message names are not
transmitted on the wire, only message field numbers.
While we're here, drastically simplify the wfe_test and sfe_test Mock
RAs, so they don't have to implement methods that aren't actually used
by the tests.
