* Move probs.go to web.
* Move probs_test.go
* Factor out probs.go from wfe
* Move context.go
* Extract context.go into web package.
* Add a constructor for TopHandler.
This is shared code between both packages. Better to have it in a single shared place.
In the process, remove the unexported signatureValidationError, which was unnecessary; all returned errors from checkAlgorithm get turned into Malformed.
In 7d04ea9 we introduced the notion of a requestEvent, which had an AddError method that could be called to log an error. In that change we also added an AddError call before every wfe.sendError, to ensure errors got logged. In dc58017, we made it so that sendError would automatically add its errors to the request event, so we wouldn't need to write AddError everywhere. However, we never cleaned up the existing AddError calls, and since then have tended to "follow local style" and add a redundant AddError before many of our sendError calls.
This change attempts to undo some of that, by removing all AddError calls that appear to be redundant with the sendError call immediately following. It also adds a section on error handling to CONTRIBUTING.md.
Previously, CAA problems were lumped in under "ConnectionProblem" or
"Unauthorized". This should make things clearer and easier to differentiate.
Fixes#3043
I thought there was a bug in NewRegistration when GetRegByKey returns an error, so I wrote a unittest... and discovered it works correctly. Oh well, now we have more tests!
We originally planned to use this to match up logs across multiple systems, but we don't currently use it, and it chews up a lot of space in our logs. We can add it back in later if/when we want to start doing that correlation.
Add a logging statement that fires when a remote VA fail causes
overall failure. Also change remoteValidationFailures into a
counter that counts the same thing, instead of a histogram. Since
the histogram had the default bucket sizes, it failed to collect
what we needed, and produced more metrics than necessary.
This commit adds a new boulder error type WrongAuthorizationState.
This error type is returned by the SA when UpdateAuthorization is
provided an authz that isn't pending. The RA and WFE are updated
accordingly such that this error percolates back through the API to the
user as a Malformed problem with a sensible description. Previously this
behaviour resulted in a ServerInternal error.
Resolves#3032
To support having problem types that use either the classic
"urn:acme:error" namespace or the new "urn:ietf:params:acme:error"
namespace as appropriate we need to prefix the problem type at runtime
right before returning it through the WFE to the user as JSON. This
commit updates the WFE/WFE2 to do this for both problems sent through
sendError as well as problems embedded in challenges. For the latter
we do not modify problems with a type that is already prefixed to
support backwards compatibility.
Resolves#2938
Note: We should cut a follow-up issue to devise a way to share some
common code between the WFE and WFE2. For example, the
prepChallengeForDisplay should probably be hoisted to a common
"web" package
* Remove all of the errors under core. Their purpose is now served by errors, and they were almost entirely unused. The remaining uses were switched to errors.
* Remove errors.NotSupportedError. It was used in only one place (ca.go), and that usage is more appropriately a ServerInternal error.
This PR implements certificate revocation for the WFE2. This
endpoint differs from others in that it supports *both* traditional key
ID based JWS request authentication in addition to embedded JWK based
JWS request authentication. The first is considered authenticated to
revoke a certificate if the signer account has valid authorizations for
all of the names in the certificate. The second is considered
authenticated if the embedded JWK that signs the request has the same
public key as the certificate being revoked.
Resolves#2952
Prior to this commit if the sa.GetAuthorization found no pending authz
rows and no authz rows for a given authz ID then sql.ErrNoRows
was returned to callers.
This commit changes the SA's GetAuthorization function to transform
sql.ErrNoRows into berrors.NotFound error. The wfe (and wfe2) are
updated to check for the GetAuthorization error being a berrors.NotFound
instance and now handle this correctly with a missing response instead of
a server internal error.
Resolves#3023
The ACME specification no longer describes "registrations" since this is
a fairly overloaded term. Instead the term used is "account". This
commit updates the WFE2 & tests throughout to replace occurrences of
"reg" and "registration" to use "acct" and "account".
NOTE: This change is strictly limited to the wfe2 package. E.g. the
RA/SA and many core objects still refer to registrations.
Resolves#2986
This commit implements certificate revocation for the WFE2. This
endpoint differs from others in that it supports *both* traditional key
ID based JWS request authentication in addition to embedded JWK based
JWS request authentication. The first is considered authenticated to

Per #3001 we should not be adding new StatsD code for metrics anymore.
This commit updates all of the WFE2 to use 1st class Prometheus stats.
Unit tests are updated accordingly.
I have broken the error stats into two counts:
1. httpErrorCount for all of the http layer client request errors (e.g.
no POST body, no content-length)
2. joseErrorCount, for all of the JOSE layer client request errors (e.g.
malformed JWS, broken signature, invalid JWK)
This commit also removes the stubbed out `TestValidKeyRollover` function
from `wfe2/verify_test.go`. This was committed accidentally and the same
functionality is covered by the `wfe2/wfe_test.go` `TestKeyRollover`
function.
RFC 7515 section 7.2.1 "General JWS JSON Serialization Syntax" describes
an optional "signatures" field that contains an array of JSON objects,
each representing a signature or MAC. ACME only uses the mandatory
"signature" field that contains the BASE64URL of a signature.
We previously checked that the parsed JWS had only one signature and
rejected accordingly but in order to be safe and ensure that nothing is
read from this "signatures" array when we intended to be using the
"signature" field this commit updates the check to explicitly reject the
"signatures" field prior to parsing with go-jose similar to how the
unprotected header is handled.
This is the second half of a clean-up of the WFE2 unit tests that were copied over from the original WFE implementation.
This PR covers TestChallenge, TestAuthorization, and TestGetCertificate.
Resolves#2928
This is the first half of a clean-up of the WFE2 unit tests that were copied over from the original WFE implementation.
I will file a follow-up pt2 PR for TestChallenge, TestAuthorization, and TestGetCert which I think are the remaining tests that could use a 🛁.
The one non-test commit changed the WFE2 index to return a problem when the method is unsupported similar to the other API endpoints. This might be inappropriate since normally the index returns XHTML and not JSON. It made testing easier but I'm open to switching back to returning a "" body and special casing the index test.
Note to reviewers: The main diff is hidden by GH by default and needs to be expanded.
Updates #2928
This PR reworks the original WFE2 JWS post validation code (primarily
from `verifyPOST()` in WFE1) to use the new "ACME v2" style of JWS verification.
For most endpoints this means switching to a style where the JWS does
*not* contain an embedded JWK and instead contains a Key ID that is used
to lookup the JWK to verify the JWS from the database. For some special
endpoints (e.g. new-reg) there is a self-authenticated JWS style that
uses the old method of embedding a JWK instead of using a Key ID
(because no account to reference by ID exists yet).
The JWS validation now lives in `wfe2/verify.go` to keep the main WFEv2
code cleaner. Compared to `verifyPOST` there has been substantial work
done to create smaller easier to test functions instead of one big
validation function. The existing WFE unit tests that were copied to the
WFE2 are largely left as they were (e.g. cruddy) and updated as
minimally as possible to support the new request validation. All tests
for new code were written in a cleaner subtest style. Cleaning up the
existing tests will be follow-up work (See https://github.com/letsencrypt/boulder/issues/2928).
Since the POST validation for the key-change and revocation endpoints
requires special care they were left out of the WFE2 implementation for now
and will return a "not implemented" error if called.
_Note to reviewers_: this is a large diff to `wfe2/wfe.go` and `wfe2/verify.go`
that Github will hide by default. You will need to click to view the diffs.

This PR renames wfe2/jose.go to wfe2/verify.go to better reflect
its purpose.
Additionally this PR moves signatureValidationError, extractJWSKey
and verifyPOST from wfe2/wfe.go to wfe2/verify.go. This is in
preparation of refactoring for the ACME v2 POST verification logic to
help keep diffs reviewable.
This commit replaces the Boulder dependency on
gopkg.in/square/go-jose.v1 with gopkg.in/square/go-jose.v2. This is
necessary both to stay in front of bitrot and because the ACME v2 work
will require a feature from go-jose.v2 for JWS validation.
The largest part of this diff is cosmetic changes:
Changing import paths
jose.JsonWebKey -> jose.JSONWebKey
jose.JsonWebSignature -> jose.JSONWebSignature
jose.JoseHeader -> jose.Header
Some more significant changes were caused by updates in the API for
for creating new jose.Signer instances. Previously we constructed
these with jose.NewSigner(algorithm, key). Now these are created with
jose.NewSigner(jose.SigningKey{},jose.SignerOptions{}). At present all
signers specify EmbedJWK: true but this will likely change with
follow-up ACME V2 work.
Another change was the removal of the jose.LoadPrivateKey function
that the wfe tests relied on. The jose v2 API removed these functions,
moving them to a cmd's main package where we can't easily import them.
This function was reimplemented in the WFE's test code & updated to fail
fast rather than return errors.
Per CONTRIBUTING.md I have verified the go-jose.v2 tests at the imported
commit pass:

This PR is the initial duplication of the WFE to create a WFE2
package. The rationale is briefly explained in `wfe2/README.md`.
Per #2822 this PR only lays the groundwork for further customization
and deduplication. Presently both the WFE and WFE2 are identical except
for the following configuration differences:
* The WFE offers HTTP and HTTPS on 4000 and 4430 respectively, the WFE2
offers HTTP on 4001 and 4431.
* The WFE has a debug port on 8000, the WFE2 uses the next free "8000
range port" and puts its debug service on 8013
