If the VA fails to validate a TLS-SNI-01 challenge because it is trying to talk TLS to a HTTP-only server return a special error message that is slightly more informative.
Right now we are using a third-party client for the Google Safe Browsing API, but Google has recently released their own [Golang library](https://github.com/google/safebrowsing) which also supports the newer v4 API. Using this library will let us avoid fixing some lingering race conditions & unpleasantness in our fork of `go-safebrowsing-api`.
This PR adds support for using the Google library & the v4 API in place of our existing fork when the `GoogleSafeBrowsingV4` feature flag is enabled in the VA "features" configuration.
Resolves https://github.com/letsencrypt/boulder/issues/1863
Per `CONTRIBUTING.md` I also ran the unit tests for the new dependency:

Presently when the VA performs a DNS-01 challenge verification it
returns the same error for the case where the remote nameserver had the
**wrong** TXT value, and when the remote nameserver had an **empty**
response for the TXT query. It would aid debugging if the user was told
which of the two failure cases was responsible for the overall challenge
failure.
This commit adds a unique error message for the empty TXT records case,
and a unit test/mock to exercise the new the error message.
Resolves#2326
This commit updates the `go-jose` dependency to [v1.1.0](https://github.com/square/go-jose/releases/tag/v1.1.0) (Commit: aa2e30fdd1fe9dd3394119af66451ae790d50e0d). Since the import path changed from `github.com/square/...` to `gopkg.in/square/go-jose.v1/` this means removing the old dep and adding the new one.
The upstream go-jose library added a `[]*x509.Certificate` member to the `JsonWebKey` struct that prevents us from using a direct equality test against two `JsonWebKey` instances. Instead we now must compare the inner `Key` members.
The `TestRegistrationContactUpdate` function from `ra_test.go` was updated to populate the `Key` members used in testing instead of only using KeyID's to allow the updated comparisons to work as intended.
The `Key` field of the `Registration` object was switched from `jose.JsonWebKey` to `*jose.JsonWebKey ` to make it easier to represent a registration w/o a Key versus using a value with a nil `JsonWebKey.Key`.
I verified the upstream unit tests pass per contributing.md:

Protobuf files need to be regenerated because (I think) Golang 1.7.3 uses a somewhat different method of ordering fields in a struct when marshaling to bytes.

The `letsencrypt/boulder-tools` image was recently updated, pulling in version
0.8.0 of certbot. That version stores the output of `certonly` requests in a
different path. In test.sh, we check out a specific tagged release of certbot in
order to get its integration tests. Prior to this commit, we were using
certbot 0.8.0 with the integration tests from version 0.6.0 of certbot,
which looked for `certonly` output in the wrong place, and failed.
This commit changes test.sh to checkout the 0.8.0 branch, and also removes a
temporary shim we used to make the `certbot` command call out to the
`letsencrypt` command.
Also, since the latest version of `letsencrypt/boulder-tools` includes an updated
`protoc-gen-go`, this change also updates the support packages to match.
While testing with real proxies I noticed the original CDR implementation was actually pretty broken, this refactors a bit and fixes a number of bugs. With this patch fallback to GPDNS over three distributed test proxies worked perfectly.
(Side note: `nginx` is not a viable forward proxy for this use as it doesn't support SSL, and a bunch of other _real_ forward proxy features, I ended up just using `squid3`.)
The main error in the previous implementation was the fallback was implemented in `getCAASet` which is only called in the old code path (the local CAA impl instead of the remote service) which mean't it wasn't actually being tested in the integration test. This also refactors a few repeated blocks into their own functions. Also there was a unicode encoding problem somewhere with the query string but for the life of me I can't figure out why it was broken now.
In https://github.com/letsencrypt/boulder/pull/774 we introduced and account key stored with the challenge. This was a stopgap fix to the now-defunct SimpleHTTP and DNS challenges in the face of https://mailarchive.ietf.org/arch/msg/acme/F71iz6qq1o_QPVhJCV4dqWf-4Yc. However, we no longer offer or implement those challenges, so the extra field is unnecessary. It also take up a huge amount of space in the challenges table, which is our biggest table. SimpleHTTP and DNS challenges were removed in https://github.com/letsencrypt/boulder/pull/1247.
We can provide a follow-up migration to delete the column later, once we have a plan for large migrations without downtime.
Fixes#1909
Clarifies the `UnknownHost` problem details error message created in the VA's `getAddr` when there is no valid IP address for the domain.
Previously this was reported as "No IPv4 addresses found for x" leading to user confusion (ref #1790) when a domain resolved to a private IP.
In this PR, logger is passed to the following callers:
NewWebFrontEndImpl
NewCertificateAuthorityImpl
NewValidationAuthorityImpl
NewAmqpRPCServer
newUpdater
NewRegistrationAuthorityServer
This reduces the usage of a global singleton logger and allows tests to consistently use a mock logger.
Fixes#1642

- Run both gRPC and AMQP servers simultaneously
- Take explicit constructor parameters and unexport fields that were previously set by users
- Remove transitional DomainCheck code in RA now that GSB is enabled.
- Remove some leftover UpdateValidation dummy methods.
Several of the `ProblemType`s had convenience functions to instantiate `ProblemDetails`s using their type and a detail message. Where these existed I did a quick scan of the codebase to convert places where callers were explicitly constructing the `ProblemDetails` to use the convenience function.
For the `ProblemType`s that did not have such a function, I created one and then converted callers to use it.
Solves #1837.
* Improve error messages in validation cases.
* Add challenge type to error detail.
This makes the errors easier to search for.
* %v->%s
* Revert boulder-config to master.
When a CAA request to Unbound times out, fall back to checking CAA via Google Public DNS' HTTPS API, through multiple proxies so as to hit geographically distributed paths. All successful multipath responses must be identical in order to succeed, and at most one can fail.

Because this event can be caused by end users, we don't want it higher than
Info. Also, it's redundant here: if this winds up being the gating factor, it
will show up in the "Validation result" log entry.

* Update protobuf package to correct version
* Add grpc client to va

* Fix all errcheck errors
* Add errcheck to test.sh
* Add a new sa.Rollback method to make handling errors in rollbacks easier.
This also causes a behavior change in the VA. If a HTTP connection is
abruptly closed after serving the headers for a non-200 response, the
reported error will be the read failure instead of the non-200.
- Remove error signatures from log methods. This means fewer places where errcheck will show ignored errors.
- Pull in latest cfssl to be compatible with errorless log messages.
- Reduce the number of message priorities we support to just those we actually use.
- AuditNotice -> AuditInfo
- Remove InfoObject (only one use, switched to Info)
- Remove EmergencyExit and related functions in favor of panic
- Remove SyslogWriter / AuditLogger separate types in favor of a single interface, Logger, that has all the logging methods on it.
- Merge mock log into logger. This allows us to unexport the internals but still override them in the mock.
- Shorten names to be compatible with Go style: New, Set, Get, Logger, NewMock, etc.
- Use a shorter log format for stdout logs.
- Remove "... Starting" log messages. We have better information in the "Versions" message logged at startup.
Motivation: The AuditLogger / SyslogWriter distinction was confusing and exposed internals only necessary for tests. Some components accepted one type and some accepted the other. This made it hard to consistently use mock loggers in tests. Also, the unnecessarily fat interface for AuditLogger made it hard to meaningfully mock out.
Also, when a certificate already exists, treat that as info, not error.
Update mock logger to allow matching by log level, and fix WFE and VA tests
correspondingly.
Windows uses \r\n as a new line character. This change should fix
issues some Windows users are seeing when they include a new line
at the end of their challenge tokens.
The RPC call returns only the updated Challenge object instead of the
whole authz, because the VA shouldn't be allowed to update any of the
other fields of the Authorization object.
