Used this as an opportunity to refactor how some tests were
making assertions about error strings.
New test helpers make it easy for an error string to be expected as an
exact string, as a string built using sprintf, as a regexp, or as a
string built to include the platform-specific x509 error string.
All of these helpers can be used in a single `wantErr` field of a test
table. They can be used for both unit tests and integration tests.

Also increase the timeout in an integration test because it is flaking
on one of the GKE environments sometimes, probably because the
Concierge controllers aren't ready fast enough before the integration
tests start.
The fuzzed value depends on which Go compiler is used. This breaks
the fips tests in CI as long as the fips compiler is a version behind
(we are still waiting for the 1.19 fips compiler to come out).
The fuzzing is still being tested by a separate unit test, so we are
not losing fuzzing test coverage.
- Change update-codegen.sh script to also generated openapi code for the
aggregated API types
- Update both aggregated API servers' configuration to make them serve
the openapi docs for the aggregated APIs
- Add new integration test which runs `kubectl explain` for all Pinniped
API resources, and all fields and subfields of those resources
- Update some the comments on the API structs
- Change some names of the tmpl files to make the filename better match
the struct names
This commit is a WIP commit because it doesn't include many tests
for the new feature.

Where possible, use securityContext settings which will work with the
most restrictive Pod Security Admission policy level (as of Kube 1.25).
Where privileged containers are needed, use the namespace-level
annotation to allow them.
Also adjust some integration tests to make similar changes to allow the
integration tests to pass on test clusters which use restricted PSAs.
This test is a little flaky in slow Kubernetes clusters. Try giving a
little more time for things to update before failing the test, to
hopefully make this test a little more reliable.
It seems that google changed it from "the gcp auth plugin is deprecated
in v1.22+, unavailable in v1.25+; use gcloud instead" to instead say
"unavailable in v1.26+". Make the matcher in category_test.go more loose
to allow both to match.
Also fix some tests that were broken by bumping golang and dependencies
in the previous commits.
Note that in addition to changes made to satisfy the linter which do not
impact the behavior of the code, this commit also adds ReadHeaderTimeout
to all usages of http.Server to satisfy the linter (and because it
seemed like a good suggestion).
When the token exchange grant type is used to get a cluster-scoped
ID token, the returned token has a new audience value. The client ID
of the client which performed the authorization was lost. This didn't
matter before, since the only client was `pinniped-cli`, but now that
dynamic clients can be registered, the information would be lost in the
cluster-scoped ID token. It could be useful for logging, tracing, or
auditing, so preserve the information by putting the client ID into the
`azp` claim in every ID token (authcode exchange, clsuter-scoped, and
refreshed ID tokens).
- For backwards compatibility with older Pinniped CLIs, the pinniped-cli
client does not need to request the username or groups scopes for them
to be granted. For dynamic clients, the usual OAuth2 rules apply:
the client must be allowed to request the scopes according to its
configuration, and the client must actually request the scopes in the
authorization request.
- If the username scope was not granted, then there will be no username
in the ID token, and the cluster-scoped token exchange will fail since
there would be no username in the resulting cluster-scoped ID token.
- The OIDC well-known discovery endpoint lists the username and groups
scopes in the scopes_supported list, and lists the username and groups
claims in the claims_supported list.
- Add username and groups scopes to the default list of scopes
put into kubeconfig files by "pinniped get kubeconfig" CLI command,
and the default list of scopes used by "pinniped login oidc" when
no list of scopes is specified in the kubeconfig file
- The warning header about group memberships changing during upstream
refresh will only be sent to the pinniped-cli client, since it is
only intended for kubectl and it could leak the username to the
client (which may not have the username scope granted) through the
warning message text.
- Add the user's username to the session storage as a new field, so that
during upstream refresh we can compare the original username from the
initial authorization to the refreshed username, even in the case when
the username scope was not granted (and therefore the username is not
stored in the ID token claims of the session storage)
- Bump the Supervisor session storage format version from 2 to 3
due to the username field being added to the session struct
- Extract commonly used string constants related to OIDC flows to api
package.
- Change some import names to make them consistent:
- Always import github.com/coreos/go-oidc/v3/oidc as "coreosoidc"
- Always import go.pinniped.dev/generated/latest/apis/supervisor/oidc
as "oidcapi"
- Always import go.pinniped.dev/internal/oidc as "oidc"
- Add dynamic client unit tests for the upstream OIDC callback and
POST login endpoints.
- Enhance a few log statements to print the full fosite error messages
into the logs where they were previously only printing the name of
the error type.
- Enhance the token exchange to check that the same client is used
compared to the client used during the original authorization and
token requests, and also check that the client has the token-exchange
grant type allowed in its configuration.
- Reduce the minimum required bcrypt cost for OIDCClient secrets
because 15 is too slow for real-life use, especially considering
that every login and every refresh flow will require two client auths.
- In unit tests, use bcrypt hashes with a cost of 4, because bcrypt
slows down by 13x when run with the race detector, and we run our
tests with the race detector enabled, causing the tests to be
unacceptably slow. The production code uses a higher minimum cost.
- Centralize all pre-computed bcrypt hashes used by unit tests to a
single place. Also extract some other useful test helpers for
unit tests related to OIDCClients.
- Add tons of unit tests for the token endpoint related to dynamic
clients for authcode exchanges, token exchanges, and refreshes.
