This PR introduces the ability for the ocsp-updater to only resubmit certificates to logs that we are missing SCTs from. Prior to this commit when a certificate was missing one or more SCTs we would submit it to every log, causing unnecessary overhead for us and the log operator.
To accomplish this a new RPC endpoint is added to the Publisher service "SubmitToSingleCT". Unlike the existing "SubmitToCT" this RPC endpoint accepts a log URI and public key in addition to the certificate DER bytes. The certificate is submitted directly to that log, and a cache of constructed resources is maintained so that subsequent submissions to the same log can reuse the stat name, verifier, and submission client.
Resolves#1679
The current ACME specification allows certificates to be revoked by a account key for an account that holds valid authorizations for every name in the certificate to be revoked. This PR adds a branch to the existing wfe.RevokeCertificate method which checks if the account key holds the required authorizations if it isn't the key for the issuing account or the certificate key.
Fixes#2318.
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:

Part of #2080.
This change vendors `crypto/x509`, `crypto/x509/pkix`, and `encoding/asn1` from 1d5f6a765d. That commit is a direct child of the Go 1.5.4 release tag, so it contains the same code as the current Go version we are using. In that commit I rewrote imports in those packages so they depend on each other internally rather than calling out to the standard library, which would cause type disagreements.
I changed the imports in each place where we're parsing CSRs, and imported under a different name `oldx509`, both to avoid collisions and make it clear what's going on. Places that only use `x509` to parse certificates are not changed, and will use the current standard library.
This will unblock us from moving to Go 1.6, and subsequently Go 1.7.
For #2001 an optimization was added to the WFE to avoid invoking the RA's `UpdateRegistration` method when a trivial (e.g. `{"resource:"reg"}`) update is received. Instead the WFE returned the trivial update back to the client immediately.
This is contrary to the ACME spec which indicates:
> Servers SHOULD NOT respond to GET requests for registration resources as these requests are not authenticated. If a client wishes to query the server for information about its account (e.g., to examine the “contact” or “certificates” fields), then it SHOULD do so by sending a POST request with an empty update. That is, it should send a JWS whose payload is trivial ({“resource”:”reg”}).
The optimization regression was captured in issue #2066 when it broke at least one client implementation.
This removes the empty reg update optimization and passes all POST's to the RA. The RA will in turn fetch the existing registration to return to the client. The second half of the #2001 optimizations remains in place, no DB UPDATE's will be performed if the new registration content doesn't differ from the existing registration content (as determine by the return of `registration.MergeUpdate`).
Since the WFE optimization is no longer in place the `FailureRegistrationAuthority` mock isn't required and is removed. Similarly `TestEmptyRegistration` in `wfe_test.go` is changed from testing for the optimization to testing for the ACME described "get registration info" behaviour.
This fixes#2066
This commit adds a new notify-mailer command. Outside of the new command, this PR also:
Adds a new SMTPConfig to cmd/config.go that is shared between the expiration mailer and the notify mailer.
Modifies mail/mailer.go to add an smtpClient interface.
Adds a dryRunClient to mail/mailer.go that implements the smtpClient interface.
Modifies the mail/mailer.go MailerImpl and constructor to use the SMTPConfig and a dialer. The missing functions from the smtpClient interface are added.
The notify-mailer command supports checkpointing through --start and --end parameters. It supports dry runs by using the new dryRunClient from the mail package when given the --dryRun flag. The speed at which emails are sent can be tweaked using the --sleep flag.
Unit tests for notify-mailer's checkpointing behaviour, the checkpoint interval/sleep parameter sanity, the sleep behaviour, and the message content construction are included in main_test.go.
Future work:
A separate command to generate the list of destination emails provided to notify-mailer
Support for using registration IDs as input and resolving the email address at runtime.
Resolves#1928. Credit to @jsha for the initial work - I'm just completing the branch he started.

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.
Fixes#1618
* Fix newVARPC sanity check logic error
* Redo style of sanity check in RA to match VA
* Switch to ServerInternal(), readd log.Info
* Add tests to make sure correct metric measured
* comments on exported symbols
* review fixes
* build an array instead of storing last
* 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.
This creates a new server, 'mail-test-srv', which is a simplistic SMTP
server that accepts mail and can report the received mail over HTTP.
An integration test is added that uses the new server to test the expiry
mailer.
The FAKECLOCK environment variable is used to force the expiry mailer to
think that the just-issued certificate is about to expire.
Additionally, the expiry mailer is modified to cleanly shut down its
SMTP connections.
Also:
- Use MockCA in the RA test instead of a real CA.
- Since the mock CA doesn't write to an SA, remove a part of the RA test that
checked that the certificate was written. That code is already tested in the CA,
where the test belongs.
- Format the constants in RA test to be more copy-and-pasteable.
- Remove Printf in mocks/log.go and test/db.go to make failed test output more readable.
In ra.checkCertificatesPerName allow a bypass of the rate limit
if the exact name set has previously been issued for. This should
make a few current scenarios people have been running into slightly
less painful.
Adds a new rate limit, certficatesPerFQDNSet, which counts certificates
with the same set of FQDNS using a table containing the hash of the dNSNames
mapped to a certificate serial. A new method is added to the SA in AddCertificate
to add this hash to the fqdnSets table, which is gated by a config bool.
Since CFSSL now supports OCSP extensions, it should be updated in
preparation for OCSP SCT stapling. Also updates CFSSL dependency
golang.org/x/crypto, including golang.org/x/crypto/ocsp.
Mocks updated to reflect interface change in cfssl.
Previously we would return a detailed errorString, which ProblemDetailsFromDNSError
would turn into a generic, uninformative "Server failure at resolver".
Now we return a new internal dnsError type, which ProblemDetailsFromDNSError can
turn into a more informative message to be shown to the user.
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.
Updates #1258
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
The RFC 5321 algorithm is to check the MX records first, and
if they are missing, check for address records. At the moment
we only check A records since there is no IPv6 support.
Fixes#1197
* Moves revocation from the CA to the OCSP-Updater, the RA will mark certificates as
revoked then wait for the OCSP-Updater to create a new (final) revoked response
* Merges the ocspResponses table with the certificateStatus table and only use UPDATES
to update the OCSP response (vs INSERT-only since this happens quite often and will
lead to an extremely large table)
instead of submitted key. This minimizes the chances of unexpected JWK fields in
the submitted key altering its interpretation without altering the lookup in the
registrations table.
In the process, fix handling of NoSuchRegistration responses.
Fixes https://github.com/letsencrypt/boulder/issues/865.
To keep the change small, I have not yet completely removed the
GetCertificateByShortSerial method from interfaces and the RPC. I will do taht
in a follow up change.
Adds a new service, Publisher, which exists to submit issued certificates to various Certificate Transparency logs. Once submitted the Publisher will also parse and store the returned SCT (Signed Certificate Timestamp) receipts that are used to prove inclusion in a specific log in the SA database. A SA migration adds the new SCT receipt table.
The Publisher only exposes one method, SubmitToCT, which is called in a goroutine by ca.IssueCertificate as to not block any other issuance operations. This method will iterate through all of the configured logs attempting to submit the certificate, and any required intermediate certificates, to them. If a submission to a log fails it will be retried the pre-configured number of times and will either use a back-off set in a Retry-After header or a pre-configured back-off between submission attempts.
This changeset is the first of a number of changes ending with serving SCT receipts in OCSP responses and purposefully leaves out the following pieces for follow-up PRs.
* A fake CT server for integration testing
* A external tool to search the database for certificates lacking a full set of SCT receipts
* A method to construct X.509 v3 extensions containing receipts for the OCSP responder
* Returned SCT signature verification (beyond just checking that the signature is of the correct type so we aren't just serving arbitrary binary blobs to clients)
