If a Redis client is configured for the SA service, OCSP responses created
during a revocation event will be written to Redis on a best effort basis.
Use the OCSP response NextUpdate time as the expiration time for the
redis entry. Change the new issuance OCSP storage to do the same.
Fixes#5888
Adds a rocsp redis client to the sa if cluster information is provided in the
sa config. If a redis cluster is configured, all new certificate OCSP
responses added with sa.AddPrecertificate will attempt to be written to
the redis cluster, but will not block or fail on errors.
Fixes: #5871
When inside a closure, it is important to not accidentally assign
to variables declared outside the scope of the closure. Doing so
causes static analysis tools (such as `errcheck`) to be unable to
evaluate the lifetime of the variable, and unable to determine if
it is appropriately read from before being assigned to again.
Fix two instances where we assign to a variable declared in the
closure's enclosing scope, rather than declaring a new variable
with the same name.
Add `stylecheck` to our list of lints, since it got separated out from
`staticcheck`. Fix the way we configure both to be clearer and not
rely on regexes.
Additionally fix a number of easy-to-change `staticcheck` and
`stylecheck` violations, allowing us to reduce our number of ignored
checks.
Part of #5681
We can scan metadata and get the age of responses.
We can scan responses and print them in base64.
Note: this issues a GET for each key, and blocks on the result. For much
faster scanning we will want to introduce parallel GETs in a subsequent
PR.
Also, add a `get` operation to get a single entry.
Fixes#5830
Add a not found error type to rocsp.
Handle redis value not found lookup errors in the ocsp-responder different
than other redis lookup errors.
Add labels to the to ocspLookup metric and delete the source used
metric. This can now be determined based on which lookup metric
reports success.
Fixes#5833
If configured, ocsp-updater will write responses to Redis in parallel
with MariaDB, giving up if Redis is slower and incrementing a stat.
Factors out the ShortIDIssuer concept from rocsp-tool into
rocsp_config.
This scans the database for certificateStatus rows, gets them signed by the CA, and writes them to Redis.
Also, bump the default PoolSize for Redis to 100.
This is a sort of proof of concept of the Redis interaction, which will
evolve into a tool for inspection and manual repair of missing entries,
if we find ourselves needing to do that.
The important bits here are rocsp/rocsp.go and
cmd/rocsp-tool/main.go. Also, the newly-vendored Redis client.
