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)
