Because we want it to implement an AuthcodeExchanger interface and
do it in a way that will be more unit test-friendly than the underlying
library that we intend to use inside its implementation.
- To better support having multiple downstream providers configured,
the authorize endpoint will share a CSRF cookie between all
downstream providers' authorize endpoints. The first time a
user's browser hits the authorize endpoint of any downstream
provider, that endpoint will set the cookie. Then if the user
starts an authorize flow with that same downstream provider or with
any other downstream provider which shares the same domain name
(i.e. differentiated by issuer path), then the same cookie will be
submitted and respected.
- Just in case we are sharing the domain name with some other app,
we sign the value of any new CSRF cookie and check the signature
when we receive the cookie. This wasn't strictly necessary since
we probably won't share a domain name with other apps, but it
wasn't hard to add this cookie signing.

Our unit tests are gonna touch a lot more corner cases than our
integration tests, so let's make them run as close to the real
implementation as possible.

We want to run all of the fosite validations in the authorize
endpoint, but we don't need to store anything yet because
we are storing what we need for later in the upstream state
parameter.

- Add a new helper method to plog to make a consistent way to log
expected errors at the info level (as opposed to unexpected
system errors that would be logged using plog.Error)

Also move definition of our oauth client and the general fosite
configuration to a helper so we can use the same config to construct
the handler for both test and production code.

Previously we were injecting the whole oauth handler chain into this function,
which meant we were essentially writing unit tests to test our tests. Let's push
some of this logic into the source code.

Does not validate incoming request parameters yet. Also is not
served on the http/https ports yet. Those will come in future commits.

- Setting a Secret in the supervisor's namespace with a special name
will cause it to get picked up and served as the supervisor's TLS
cert for any request which does not have a matching SNI cert.
- This is especially useful for when there is no DNS record for an
issuer and the user will be accessing it via IP address. This
is not how we would expect it to be used in production, but it
might be useful for other cases.
- Includes a new integration test
- Also suppress all of the warnings about ignoring the error returned by
Close() in lines like `defer x.Close()` to make GoLand happier
- TLS certificates can be configured on the OIDCProviderConfig using
the `secretName` field.
- When listening for incoming TLS connections, choose the TLS cert
based on the SNI hostname of the incoming request.
- Because SNI hostname information on incoming requests does not include
the port number of the request, we add a validation that
OIDCProviderConfigs where the issuer hostnames (not including port
number) are the same must use the same `secretName`.
- Note that this approach does not yet support requests made to an
IP address instead of a hostname. Also note that `localhost` is
considered a hostname by SNI.
- Add port 443 as a container port to the pod spec.
- A new controller watches for TLS secrets and caches them in memory.
That same in-memory cache is used while servicing incoming connections
on the TLS port.
- Make it easy to configure both port 443 and/or port 80 for various
Service types using our ytt templates for the supervisor.
- When deploying to kind, add another nodeport and forward it to the
host on another port to expose our new HTTPS supervisor port to the
host.
- When two different Issuers have the same host (i.e. they differ
only by path) then they must have the same secretName. This is because
it wouldn't make sense for there to be two different TLS certificates
for one host. Find any that do not have the same secret name to
put an error status on them and to avoid serving OIDC endpoints for
them. The host comparison is case-insensitive.
- Issuer hostnames should be treated as case-insensitive, because
DNS hostnames are case-insensitive. So https://me.com and
https://mE.cOm are duplicate issuers. However, paths are
case-sensitive, so https://me.com/A and https://me.com/a are
different issuers. Fixed this in the issuer validations and in the
OIDC Manager's request router logic.
- The OIDCProviderConfigWatcherController synchronizes the
OIDCProviderConfig settings to dynamically mount and unmount the
OIDC discovery endpoints for each provider
- Integration test passes but unit tests need to be added still
