Jacob Hoffman-Andrews 6b8b6a37c0 Update chisel2 and boulder-tools (#3495)
This change updates boulder-tools to use Go 1.10, and references a
newly-pushed image built using that new config.

Since boulder-tools pulls in the latest Certbot master at the time of
build, this also pulls in the latest changes to Certbot's acme module,
which now supports ACME v2. This means we no longer have to check out
the special acme-v2-integration branch in our integration tests.

This also updates chisel2.py to reflect some of the API changes that
landed in the acme module as it was merged to master.

Since we don't need additional checkouts to get the ACMEv2-compatible
version of the acme module, we can include it in the default RUN set for
local tests.

Jacob Hoffman-Andrews 9da5a7e1fc Cleanup: TLS and GRPC configs are mandatory. (#3476)
Our various main.go functions gated some key code on whether the TLS
and/or GRPC config fields were present. Now that those fields are fully
deployed in production, we can simplify the code and require them.
    
Also, rename tls to tlsConfig everywhere to avoid confusion with the tls
package.
    
Avoid assigning to the same err from two different goroutines in
boulder-ca (fix a race).

Restore gRPC metrics (#3265)
The go-grpc-prometheus package by default registers its metrics with Prometheus' global registry. In #3167, when we stopped using the global registry, we accidentally lost our gRPC metrics. This change adds them back.

Specifically, it adds two convenience functions, one for clients and one for servers, that makes the necessary metrics object and registers it. We run these in the main function of each server.

I considered adding these as part of StatsAndLogging, but the corresponding ClientMetrics and ServerMetrics objects (defined by go-grpc-prometheus) need to be subsequently made available during construction of the gRPC clients and servers. We could add them as fields on Scope, but this seemed like a little too much tight coupling.

Also, update go-grpc-prometheus to get the necessary methods.

```
$ go test github.com/grpc-ecosystem/go-grpc-prometheus/...
ok      github.com/grpc-ecosystem/go-grpc-prometheus    0.069s
?       github.com/grpc-ecosystem/go-grpc-prometheus/examples/testproto [no test files]

Jacob Hoffman-Andrews f366e45756 Remove global state from metrics gathering (#3167)
Previously, we used prometheus.DefaultRegisterer to register our stats, which uses global state to export its HTTP stats. We also used net/http/pprof's behavior of registering to the default global HTTP ServeMux, via DebugServer, which starts an HTTP server that uses that global ServeMux.

In this change, I merge DebugServer's functions into StatsAndLogging. StatsAndLogging now takes an address parameter and fires off an HTTP server in a goroutine. That HTTP server is newly defined, and doesn't use DefaultServeMux. On it is registered the Prometheus stats handler, and handlers for the various pprof traces. In the process I split StatsAndLogging internally into two functions: makeStats and MakeLogger. I didn't port across the expvar variable exporting, which serves a similar function to Prometheus stats but which we never use.

One nice immediate effect of this change: Since StatsAndLogging now requires and address, I noticed a bunch of commands that called StatsAndLogging, and passed around the resulting Scope, but never made use of it because they didn't run a DebugServer. Under the old StatsD world, these command still could have exported their stats by pushing, but since we moved to Prometheus their stats stopped being collected. We haven't used any of these stats, so instead of adding debug ports to all short-lived commands, or setting up a push gateway, I simply removed them and switched those commands to initialize only a Logger, no stats.

Jacob Hoffman-Andrews 78f454bdfd Set timeout for GSB requests. (#3136)
safebrowsing defaults to a one minute timeout for its requests. Set a much lower
one so that we don't timeout new-authzs when communicating with safebrowsing is
slow.

Jacob Hoffman-Andrews 4128e0d95a Add time-dependent integration testing (#3060)
Fixes #3020.

In order to write integration tests for some features, especially related to rate limiting, rechecking of CAA, and expiration of authzs, orders, and certs, we need to be able to fake the passage of time in integration tests.

To do so, this change switches out all clock.Default() instances for cmd.Clock(), which can be set manually with the FAKECLOCK environment variable. integration-test.py now starts up all servers once before the main body of tests, with FAKECLOCK set to a date 70 days ago, and does some initial setup for a new integration test case. That test case tries to fetch a 70-day-old authz URL, and expects it to 404.

In order to make this work, I also had to change a number of our test binaries to shut down cleanly in response to SIGTERM. Without that change, stopping the servers between the setup phase and the main tests caused startservers.check() to fail, because some processes exited with nonzero status.

Note: This is an initial stab at things, to prove out the technique. Long-term, I think we will want to use an idiom where test cases are classes that have a number of optional setup phases that may be run at e.g. 70 days prior and 5 days prior. This could help us avoid a proliferation of global state as we add more time-dependent test cases.

Jacob Hoffman-Andrews 20ec1e3e4e Filter spurious shutdown errors. (#3052)
Previously, we would produce an error an a nonzero status code on shutdown,
because gRPC's GracefulStop would cause s.Serve() to return an error. Now we
filter that specific error and treat it as success. This also allows us to kill
process with SIGTERM instead of SIGKILL in integration tests.

Fixes #2410.

Jacob Hoffman-Andrews b0c7bc1bee Recheck CAA for authorizations older than 8 hours (#3014)
Fixes #2889.

VA now implements two gRPC services: VA and CAA. These both run on the same port, but this allows implementation of the IsCAAValid RPC to skip using the gRPC wrappers, and makes it easier to potentially separate the service into its own package in the future.

RA.NewCertificate now checks the expiration times of authorizations, and will call out to VA to recheck CAA for those authorizations that were not validated recently enough.

Roland Bracewell Shoemaker 05d869b005 Rename DNSResolver -> DNSClient (#2878)
Fixes #639.

Jacob Hoffman-Andrews 63a25bf913 Remove clientName everywhere. (#2862)
This used to be used for AMQP queue names. Now that AMQP is gone, these consts
were only used when printing a version string at startup. This changes
VersionString to just use the name of the current program, and removes
`const clientName = ` from many of our main.go's.

Roland Bracewell Shoemaker 088b872287 Implement multi VA validation (#2802)
Adds basic multi-path validation functionality. A new method `performRemoteValidation` is added to `boulder-va` which is called if it is configured with a list of remote VA gRPC addresses. In this initial implementation the remote VAs are only used to check the validation result of the main VA, if all of the remote validations succeed but the local validation failed, the overall validation will still fail. Remote VAs use the exact same code as the local VA to perform validation. If the local validation succeeds then a configured quorum of the remote VA successes must be met in order to fully complete the validation.

This implementation assumes that metrics are collected from the remote VAs in order to have visibility into their individual validation latencies etc.

Fixes #2621.

Jacob Hoffman-Andrews b17b5c72a6 Remove statsd from Boulder (#2752)
This removes the config and code to output to statsd.

- Change `cmd.StatsAndLogging` to output a `Scope`, not a `Statter`.
- Remove the prefixing of component name (e.g. "VA") in front of stats; this was stripped by `autoProm` but now no longer needs to be.
- Delete vendored statsd client.
- Delete `MockStatter` (generated by gomock) and `mocks.Statter` (hand generated) in favor of mocking `metrics.Scope`, which is the interface we now use everywhere.
- Remove a few unused methods on `metrics.Scope`, and update its generated mock.
- Refactor `autoProm` and add `autoRegisterer`, which can be included in a `metrics.Scope`, avoiding global state. `autoProm` now registers everything with the `prometheus.Registerer` it is given.
- Change va_test.go's `setup()` to not return a stats object; instead the individual tests that care about stats override `va.stats` directly.

Fixes #2639, #2733.

Daniel McCarney 15e73edc5a Google Safe Browsing V4 Improvements (#2504)
This PR has three primary contributions:

1. The existing code for using the V4 safe browsing API introduced in #2446 had some bugs that are fixed in this PR.
2. A gsb-test-srv is added to provide a mock Google Safebrowsing V4 server for integration testing purposes.
3. A short integration test is added to test end-to-end GSB lookup for an "unsafe" domain.

For 1) most notably Boulder was assuming the new V4 library accepted a directory for its database persistence when it instead expects an existing file to be provided. Additionally the VA wasn't properly instantiating feature flags preventing the V4 api from being used by the VA.

For 2) the test server is designed to have a fixed set of "bad" domains (Currently just honest.achmeds.discount.hosting.com). When asked for a database update by a client it will package the list of bad domains up & send them to the client. When the client is asked to do a URL lookup it will check the local database for a matching prefix, and if found, perform a lookup against the test server. The test server will process the lookup and increment a count for how many times the bad domain was asked about.

For 3) the Boulder startservers.py was updated to start the gsb-test-srv and the VA is configured to talk to it using the V4 API. The integration test consists of attempting issuance for a domain pre-configured in the gsb-test-srv as a bad domain. If the issuance succeeds we know the GSB lookup code is faulty. If the issuance fails, we check that the gsb-test-srv received the correct number of lookups for the "bad" domain and fail if the expected isn't reality.

Notes for reviewers:

* The gsb-test-srv has to be started before anything will use it. Right now the v4 library handles database update request failures poorly and will not retry for 30min. See google/safebrowsing#44 for more information.
* There's not an easy way to test for "good" domain lookups, only hits against the list. The design of the V4 API is such that a list of prefixes is delivered to the client in the db update phase and if the domain in question matches no prefixes then the lookup is deemed unneccesary and not performed. I experimented with sending 256 1 byte prefixes to try and trick the client to always do a lookup, but the min prefix size is 4 bytes and enumerating all possible prefixes seemed gross.
* The test server has a /add endpoint that could be used by integration tests to add new domains to the block list, but it isn't being used presently. The trouble is that the client only updates its database every 30 minutes at present, and so adding a new domain will only take affect after the client updates the database.

Resolves #2448

Jacob Hoffman-Andrews 510e279208 Simplify gRPC TLS configs. (#2470)
Previously, a given binary would have three TLS config fields (CA cert, cert,
key) for its gRPC server, plus each of its configured gRPC clients. In typical
use, we expect all three of those to be the same across both servers and clients
within a given binary.

This change reuses the TLSConfig type already defined for use with AMQP, adds a
Load() convenience function that turns it into a *tls.Config, and configures it
for use with all of the binaries. This should make configuration easier and more
robust, since it more closely matches usage.

This change preserves temporary backwards-compatibility for the
ocsp-updater->publisher RPCs, since those are the only instances of gRPC
currently enabled in production.

Daniel McCarney 74e281c1ce Switch to Google's v4 safebrowsing library. (#2446)
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

The LookupIPv6 flag has been enabled in production and isn't required anymore. This PR removes the flag entirely.

The errA and errAAAA error handling in LookupHost is left as-is, meaning that a non-nil errAAAA will not be returned to the caller. This matches the existing behaviour, and the expectations of the TestDNSLookupHost unit tests.

This commit also removes the tests from TestDNSLookupHost that tested the LookupIPv6 == false behaviours since those are no longer implemented.

Jacob Hoffman-Andrews ecc04e8e61 Refactor log package (#1717)
- 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.

Jeff Hodges 116ce96326 add retries and context deadlines to DNSResolver
This provides a means to add retries to DNS look ups, and, with some
future work, end retries early if our request deadline is blown. That
future work is tagged with #1292.

Jeff Hodges e36895c9c5 bring RTT metrics inside DNSResolver
This moves the RTT metrics calculation inside of the DNSResolver. This
cleans up code in the RA and VA and makes some adding retries to the
DNSResolver less ugly to do.

Note: this will put `Rate` and `RTT` after the name of DNS query
type (`A`, `MX`, etc.). I think that's fine and desirable. We aren't
using this data in alerts or many dashboards, yet, so a flag day is
okay.

Fixes #1124
