This updates va.proto to use proto3 syntax, and updates
all clients of the autogenerated code to use the new types.
In particular, it removes indirection from built-in types
(proto3 uses ints, rather than pointers to ints, for example).

ra.PerformValidation's goroutine surfaces errors not by returning them,
but by accumulating them into the `prob`variable and saving them to
the database. This makes it possible for processing to continue even
in error cases when it should (mostly) halt. This change fixes a bug
where we would try to access a member of the result returned from
va.PerformValidation, even if that function call had returned an error.
ACME Challenges are well-known strings ("http-01", "dns-01", and
"tlsalpn-01") identifying which kind of challenge should be used
to verify control of a domain. Because they are well-known and
only certain values are valid, it is better to represent them as
something more akin to an enum than as bare strings. This also
improves our ability to ensure that an AcmeChallenge is not
accidentally used as some other kind of string in a different
context. This change also brings them closer in line with the
existing core.AcmeResource and core.OCSPStatus string enums.
Fixes#5009
Partial revert of #4981 / 62eae60. Some HSMs have a small number
of slots and require storing multiple keys per slot (differentiated
by keyID, which we now look up based on the public key per #4992).
Previously, canceled remote validations were simply noted and then
dropped on the floor. This should be safe, as they're theoretically
only canceled when the parent span (i.e. the local PerformValidation
RPC) ends. But for the sake of defense-in-depth, it seems better to
correctly mark canceled remote validations as having Problems, so
that their results cannot be accidentally used anywhere.
This results in a test behavior change: if EnforceMultiVA is on, and
some RPCs are canceled, this now results in validation failure. This
should not have any production impact, because remote validations
should only be canceled when the parent RPC early-exits, but that only
happens when EnforceMultiVA is not enabled. These tests now test a
case where the other remote validations were canceled for some other
reason, which should result in validation failure.
Go 1.15rc2 was released today. The diff from rc1 only includes one
change to the crypto/ package, but worth upgrading just to be ready
for the official 1.15 stable release.
This moves x509Signer from cmd/ceremony into pkcs11helpers. It also
adds helper functions getPublicKeyID and getPrivateKey, copied and
adapted from pkcs11key. These act as counterparts to the existing
GetRSAPublicKey and GetECDSAPublicKey, which go from an object handle
to a Go public key object (and are used after key generation).
Fixes#4918
Updates the type of the ValidationAuthority's PerformValidation
method to be identical to that of the corresponding auto-generated
grpc method, i.e. directly taking and returning proto message
types, rather than exploded arguments.
This allows all logic to be removed from the VA wrappers, which
will allow them to be fully removed after the migration to proto3.
Also updates all tests and VA clients to adopt the new interface.
Depends on #4983 (do not review first four commits)
Part of #4956
Our proto files had a variety of indentation styles: 2 spaces,
4 spaces, 8 spaces, and tabs; sometimes mixed within the same
file. The proto3 style guide[1] says to use 2-space indents,
so this change standardizes on that.

We'd like to issue certs with no CN eventually, but it's not
going to happen any time soon. In the mean time, the existing
code never gets exercised and is rather complex, so this
removes it.
This enables the gosec linter. It also disables a number of
warnings which it emits on the current codebase. Some of these
(e.g. G104: Errors unhandled) we expect to leave disabled
permanently; others (e.g. G601: Implicit memory aliasing in for loop)
we expect to fix and then enable to prevent regressions.
Part of #4948
This mocks out the signer type rather than mocking out the pkcs11
object, making the test less dependent on the internals of our
pkcs11helpers package.
Part of refactorings related to #4918.
This is the only method on the ca which uses a non-proto
type as its request or response value. Changing this to
use a proto removes the last logic from the wrappers,
allowing them to be removed in a future CL. It also makes
the interface more uniform and easier to reason about.
Issue: #4940
Because these `wfe.sendError()` calls were not followed
by `return`s, the wfe was sending both them and the
next error encountered. In some cases, this could result
in the wrong HTTP response code being set, as that is
determined by the last error sent.
Previously we were relying on a "more" boolean returned from
FindObjects. But according to
https://pkg.go.dev/github.com/miekg/pkcs11?tab=doc#Ctx.FindObjects,
> The returned boolean value is deprecated and should be ignored.
Instead, we ask for more objects than we need and error if we get more
than 1.
Add a test, and in the process split up the relevant test into
multiple smaller test cases.
Introduces a new generic helper utility to check that
fields of proto messages are non-nil and non-zero.
Uses this helper to simplify the ca RPC wrapper
methods, moving their completeness checks into
the underlying method handler. Also annotates the
completeness checks to justify which fields are or
are not being checked for future readers. Finally,
removes the similar non-nil checks from the client
wrappers, where they provide no marginal value.
Follow-up changes will do the same for other RPC
services, migrate said services to proto3, and change
the IssueCertificateForPrecertificate method to return
a corepb.Certificate instead of a core.Certificate, like
the other methods on the ca service.
Issues: #4955
We previously used mixed case names for proto imports
(e.g. both `caPB` and `rapb`), sometimes in the same file.
This change standardizes on the all-lowercase spelling,
which was predominant throughout the codebase.
Previously, this limit was bucketed by hour, but that created too much
sudden traffic at the beginning of each hour as accounts' rate limits
expired. Chunking by the minute should make it possible to smooth out
traffic more.
This was necessary to work around a poor interaction between
Go 1.4.x and unpatched linux kernels. Although we are still using
the same version of Go, and the Linux project only released the
fix in kernel 5.4.2 and later, Ubuntu has backported the fix into
Focal Fossa 20.04's 5.4.0 kernel. Therefore this workaround is
no longer needed.

This also removes one need for elevated permissions, making it
easier to use docker rootless for development.
Simplify database interactions
This change is a result of an audit of all places where
Go code directly constructs SQL queries and executes them
against a dbMap, with the goal of eliminating all instances
of constructing a well-known object type (such as a
core.CertificateStatus) from explicitly-listed database columns.
Instead, we should be relying on helper functions defined in the
sa itself to determine which columns are relevant for the
construction of any given object.
This audit did not find many places where this was occurring. It
did reveal a few simplifications, which are contained in this
change:
1) Greater use of existing SelectFoo methods provided by models.go
2) Streamlining of various SelectSingularFoo methods to always
select by serial string, rather than user-provided WHERE clause
3) One spot (in ocsp-responder) where using a well-known type seemed
better than using a more minimal custom type

This updates va.proto to use proto3 syntax, and updates
all clients of the autogenerated code to use the new types. In
particular, it removes indirection from built-in types (proto3
uses ints, rather than pointers to ints, for example).
Fixes#4956
We had some duplicated code related to opening the PKCS#11 session and
generating a signer, so I pulled it out into a separate function. This
function also takes an issuer so it can verify that the public key
matches what's expected.
This updates the ca.proto to use proto3 syntax, and updates
all clients of the autogenerated code to use the new types. In
particular, it removes indirection from built-in types (proto3
uses ints, rather than pointers to ints, for example).
It also updates a few instances where tests were being
conducted to see if various object fields were nil to instead
check for those fields' new zero-value.
Fixes#4940
