leader election: use better duration defaults
OpenShift has good defaults for these duration fields that we can
use instead of coming up with them ourselves:

e14e06ba8d/pkg/config/leaderelection/leaderelection.go (L87-L109)

Copied here for easy future reference:

// We want to be able to tolerate 60s of kube-apiserver disruption without causing pod restarts.
// We want the graceful lease re-acquisition fairly quick to avoid waits on new deployments and other rollouts.
// We want a single set of guidance for nearly every lease in openshift.  If you're special, we'll let you know.
// 1. clock skew tolerance is leaseDuration-renewDeadline == 30s
// 2. kube-apiserver downtime tolerance is == 78s
//      lastRetry=floor(renewDeadline/retryPeriod)*retryPeriod == 104
//      downtimeTolerance = lastRetry-retryPeriod == 78s
// 3. worst non-graceful lease acquisition is leaseDuration+retryPeriod == 163s
// 4. worst graceful lease acquisition is retryPeriod == 26s
if ret.LeaseDuration.Duration == 0 {
	ret.LeaseDuration.Duration = 137 * time.Second
}

if ret.RenewDeadline.Duration == 0 {
	// this gives 107/26=4 retries and allows for 137-107=30 seconds of clock skew
	// if the kube-apiserver is unavailable for 60s starting just before t=26 (the first renew),
	// then we will retry on 26s intervals until t=104 (kube-apiserver came back up at 86), and there will
	// be 33 seconds of extra time before the lease is lost.
	ret.RenewDeadline.Duration = 107 * time.Second
}
if ret.RetryPeriod.Duration == 0 {
	ret.RetryPeriod.Duration = 26 * time.Second
}

leader election: in-memory leader status is stopped before release
This change fixes a small race condition that occurred when the
current leader failed to renew its lease.  Before this change, the
leader would first release the lease via the Kube API and then would
update its in-memory status to reflect that change.  Now those
events occur in the reverse (i.e. correct) order.

impersonatorconfig: only unload dynamiccert when proxy is disabled
In the upstream dynamiccertificates package, we rely on two pieces
of code:

1. DynamicServingCertificateController.newTLSContent which calls
   - clientCA.CurrentCABundleContent
   - servingCert.CurrentCertKeyContent
2. unionCAContent.VerifyOptions which calls
   - unionCAContent.CurrentCABundleContent

This results in calls to our tlsServingCertDynamicCertProvider and
impersonationSigningCertProvider.  If we Unset these providers, we
subtly break these consumers.  At best this results in test slowness
and flakes while we wait for reconcile loops to converge.  At worst,
it results in actual errors during runtime.  For example, we
previously would Unset the impersonationSigningCertProvider on any
sync loop error (even a transient one caused by a network blip or
a conflict between writes from different replicas of the concierge).
This would cause us to transiently fail to issue new certificates
from the token credential require API.  It would also cause us to
transiently fail to authenticate previously issued client certs
(which results in occasional Unauthorized errors in CI).

84c3c3aa9c Optionally allow OIDC password grant for CLI-based login experience
- Add `AllowPasswordGrant` boolean field to OIDCIdentityProvider's spec
- The oidc upstream watcher controller copies the value of
  `AllowPasswordGrant` into the configuration of the cached provider
- Add password grant to the UpstreamOIDCIdentityProviderI interface
  which is implemented by the cached provider instance for use in the
  authorization endpoint
- Enhance the IDP discovery endpoint to return the supported "flows"
  for each IDP ("cli_password" and/or "browser_authcode")
- Enhance `pinniped get kubeconfig` to help the user choose the desired
  flow for the selected IDP, and to write the flow into the resulting
  kubeconfg
- Enhance `pinniped login oidc` to have a flow flag to tell it which
  client-side flow it should use for auth (CLI-based or browser-based)
- In the Dex config, allow the resource owner password grant, which Dex
  implements to also return ID tokens, for use in integration tests
- Enhance the authorize endpoint to perform password grant when
  requested by the incoming headers. This commit does not include unit
  tests for the enhancements to the authorize endpoint, which will come
  in the next commit
- Extract some shared helpers from the callback endpoint to share the
  code with the authorize endpoint
- Add new integration tests

Switch to a slimmer distroless base image.
At a high level, it switches us to a distroless base container image, but that also includes several related bits:

- Add a writable /tmp but make the rest of our filesystems read-only at runtime.

- Condense our main server binaries into a single pinniped-server binary. This saves a bunch of space in
  the image due to duplicated library code. The correct behavior is dispatched based on `os.Args[0]`, and
  the `pinniped-server` binary is symlinked to `pinniped-concierge` and `pinniped-supervisor`.

- Strip debug symbols from our binaries. These aren't really useful in a distroless image anyway and all the
  normal stuff you'd expect to work, such as stack traces, still does.

- Add a separate `pinniped-concierge-kube-cert-agent` binary with "sleep" and "print" functionality instead of
  using builtin /bin/sleep and /bin/cat for the kube-cert-agent. This is split from the main server binary
  because the loading/init time of the main server binary was too large for the tiny resource footprint we
  established in our kube-cert-agent PodSpec. Using a separate binary eliminates this issue and the extra
  binary adds only around 1.5MiB of image size.

- Switch the kube-cert-agent code to use a JSON `{"tls.crt": "<b64 cert>", "tls.key": "<b64 key>"}` format.
  This is more robust to unexpected input formatting than the old code, which simply concatenated the files
  with some extra newlines and split on whitespace.

- Update integration tests that made now-invalid assumptions about the `pinniped-server` image.

certs_expirer: be specific about what secret to delete
This change fixes a race that can occur because we have multiple
writers with no leader election lock.

1. TestAPIServingCertificateAutoCreationAndRotation/automatic
   expires the current serving certificate
2. CertsExpirerController 1 deletes expired serving certificate
3. CertsExpirerController 2 starts deletion of expired serving
   certificate but has not done so yet
4. CertsManagerController 1 creates new serving certificate
5. TestAPIServingCertificateAutoCreationAndRotation/automatic
   records the new serving certificate
6. CertsExpirerController 2 finishes deletion, and thus deletes the
   newly created serving certificate instead of the old one
7. CertsManagerController 2 creates new serving certificate
8. TestAPIServingCertificateAutoCreationAndRotation/automatic keeps
   running and eventually times out because it is expecting the
   serving certificate created by CertsManagerController 2 to match
   the value it recorded from CertsManagerController 1 (which will
   never happen since that certificate was incorrectly deleted).

2bba39d723 TestAgentController unit test is flaky, try to add workaround
TestAgentController really runs the controller and evaluates multiple
calls to the controller's Sync with real informers caching updates.
There is a large amount of non-determinism in this unit test, and it
does not always behave the same way. Because it makes assertions about
the specific errors that should be returned by Sync, it was not
accounting for some errors that are only returned by Sync once in a
while depending on the exact (unpredictable) order of operations.

This commit doesn't fix the non-determinism in the test, but rather
tries to work around it by also allowing other (undesired but
inevitable) error messages to appear in the list of actual error
messages returned by the calls to the Sync function.

This is a new pacakge internal/oidc/provider/formposthtml containing a number of static files embedded using the relatively recent Go "//go:embed" functionality introduced in Go 1.16 (https://blog.golang.org/go1.16).

The Javascript and CSS files are minifiied and injected to make a single self-contained HTML response. There is a special Content-Security-Policy helper to calculate hash-based script-src and style-src rules.

This new code is covered by a new integration test that exercises the JS/HTML functionality in a real browser outside of the rest of the Supervisor.

f0d120a6ca Fix broken upstream OIDC discovery timeout added in previous commit
After noticing that the upstream OIDC discovery calls can hang
indefinitely, I had tried to impose a one minute timeout on them
by giving them a timeout context. However, I hadn't noticed that the
context also gets passed into the JWKS fetching object, which gets
added to our cache and used later. Therefore the timeout context
was added to the cache and timed out while sitting in the cache,
causing later JWKS fetchers to fail.

This commit is trying again to impose a reasonable timeout on these
discovery and JWKS calls, but this time by using http.Client's Timeout
field, which is documented to be a timeout for *each* request/response
cycle, so hopefully this is a more appropriate way to impose a timeout
for this use case. The http.Client instance ends up in the cache on
the JWKS fetcher object, so the timeout should apply to each JWKS
request as well.

Requests that can hang forever are effectively a server-side resource
leak, which could theoretically be taken advantage of in a denial of
service attempt, so it would be nice to avoid having them.

Use a custom type for our static CLI client (smaller change).
Before this change, we used the `fosite.DefaultOpenIDConnectClient{}` struct, which implements the  `fosite.Client` and `fosite.OpenIDConnectClient` interfaces. For a future change, we also need to implement some additional optional interfaces, so we can no longer use the provided default types. Instead, we now use a custom `clientregistry.Client{}` struct, which implements all the requisite interfaces and can be extended to handle the new functionality (in a future change).

There is also a new `clientregistry.StaticRegistry{}` struct, which implements the `fosite.ClientManager` and looks up our single static client. We could potentially extend this in the future with a registry backed by Kubernetes API, for example.

This should be 100% refactor, with no user-observable change.

impersonator: honor anonymous authentication being disabled
When anonymous authentication is disabled, the impersonation proxy
will no longer authenticate anonymous requests other than calls to
the token credential request API (this API is used to retrieve
credentials and thus must be accessed anonymously).

Tolerate NotFound when deleting services in impersonatorconfig.
When a CredentialIssuer is switched from one service type to another (or switched to disabled mode), the `impersonatorconfig` controller will delete the previous Service, if any. Normally one Concierge pod will succeed to delete this initially and any other pods will see a NotFound error.

Before this change, the NotFound would bubble up and cause the strategy to enter a ErrorDuringSetup status until the next reconcile loop. We now handle this case without reporting an error.

Don't reconcile Service ports in impersonatorconfig.
These are tricky because a real load balancer controller (e.g., on GKE) will overwrite and set NodePort, so we can't blindly set the desired state of this fields.

For now, we will just skip reconciling these. In the future, we could be more clever about merging them together with the current state.

d2251d2ea7 Use base64 binary-encoded value as UID for LDAP
This is to allow the use of binary LDAP entry attributes as the UID.
For example, a user might like to configure AD’s objectGUID or maybe
objectSid attributes as the UID attribute.

This negatively impacts the readability of the UID when it did not come
from a binary value, but we're considering this an okay trade-off to
keep things simple for now. In the future, we may offer more
customizable encoding options for binary attributes.

These UIDs are currently only used in the downstream OIDC `sub` claim.
They do not effect the user's identity on the Kubernetes cluster,
which is only based on their mapped username and group memberships from
the upstream identity provider. We are not currently supporting any
special encoding for those username and group name LDAP attributes, so
their values in the LDAP entry must be ASCII or UTF-8 in order for them
to be interpreted correctly.

Create CredentialIssuer at install, not runtime.
Previously, our controllers would automatically create a CredentialIssuer with a singleton name. The helpers we had for this also used "raw" client access and did not take advantage of the informer cache pattern.

With this change, the CredentialIssuer is always created at install time in the ytt YAML. The controllers now only update the existing CredentialIssuer status, and they do so using the informer cache as much as possible.

This change is targeted at only the kubecertagent controller to start. The impersonatorconfig controller will be updated in a following PR along with other changes.

simply by using the same service account as the main Concierge pods.

We still set `automountServiceAccountToken: false`, so this should not actually give any useful permissions to the

Refactor kube-cert-agent controllers to use a Deployment.
This is a relatively large rewrite of much of the kube-cert-agent controllers. Instead of managing raw Pod objects, they now create a single Deployment and let the builtin k8s controller handle it from there.

This reduces the amount of code we need and should handle a number of edge cases better, especially those where a Pod becomes "wedged" and needs to be recreated.

impersonation proxy: add nested impersonation support
This change updates the impersonator logic to use the delegated
authorizer for all non-rest verbs such as impersonate.  This allows
it to correctly perform authorization checks for incoming requests
that set impersonation headers while not performing unnecessary
checks that are already handled by KAS.

The audit layer is enabled to track the original user who made the
request.  This information is then included in a reserved extra

83085aa3d6 Retest the server connection when the bind Secret has changed
Unfortunately, Secrets do not seem to have a Generation field, so we
use the ResourceVersion field instead. This means that any change to
the Secret will cause us to retry the connection to the LDAP server,
even if the username and password fields in the Secret were not
changed. Seems like an okay trade-off for this early draft of the
controller compared to a more complex implementation.

8e438e22e9 Only test the server connection when the spec has changed
This early version of the controller is not intended to act as an
ongoing health check for your upstream LDAP server. It will connect
to the LDAP server to essentially "lint" your configuration once.
It will do it again only when you change your configuration. To account
for transient errors, it will keep trying to connect to the server
until it succeeds once.

This commit does not include looking for changes in the associated bind
user username/password Secret.

- Empty usernames and passwords are already prevented by our endpoint

f6ded84f07 Implement upstream LDAP support in auth_handler.go
- When the upstream IDP is an LDAP IDP and the user's LDAP username and
  password are received as new custom headers, then authenticate the
  user and, if authentication was successful, return a redirect with
  an authcode. Handle errors according to the OAuth/OIDC specs.
- Still does not support having multiple upstream IDPs defined at the
  same time, which was an existing limitation of this endpoint.
- Does not yet include the actual LDAP authentication, which is
  hidden behind an interface from the point of view of auth_handler.go
- Move the oidctestutil package to the testutil directory.
- Add an interface for Fosite storage to avoid a cyclical test
  dependency.
- Add GetURL() to the UpstreamLDAPIdentityProviderI interface.
- Extract test helpers to be shared between callback_handler_test.go
  and auth_handler_test.go because the authcode and fosite storage
  assertions should be identical.
- Backfill Content-Type assertions in callback_handler_test.go.

c82f568b2c certauthority.go: Refactor issuing client versus server certs
We were previously issuing both client certs and server certs with
both extended key usages included. Split the Issue*() methods into
separate methods for issuing server certs versus client certs so
they can have different extended key usages tailored for each use
case.

Also took the opportunity to clean up the parameters of the Issue*()
methods and New() methods to more closely match how we prefer to call
them. We were always only passing the common name part of the
pkix.Name to New(), so now the New() method just takes the common name
as a string. When making a server cert, we don't need to set the
deprecated common name field, so remove that param. When making a client
cert, we're always making it in the format expected by the Kube API
server, so just accept the username and group as parameters directly.

0b300cbe42 Use TokenCredentialRequest instead of base64 token with impersonator
To make an impersonation request, first make a TokenCredentialRequest
to get a certificate. That cert will either be issued by the Kube
API server's CA or by a new CA specific to the impersonator. Either
way, you can then make a request to the impersonator and present
that client cert for auth and the impersonator will accept it and
make the impesonation call on your behalf.

The impersonator http handler now borrows some Kube library code
to handle request processing. This will allow us to more closely
mimic the behavior of a real API server, e.g. the client cert
auth will work exactly like the real API server.

d8c6894cbc All controller unit tests should not cancel context until test is over
All controller unit tests were accidentally using a timeout context
for the informers, instead of a cancel context which stays alive until
each test is completely finished. There is no reason to risk
unpredictable behavior of a timeout being reached during an individual
test, even though with the previous 3 second timeout it could only be
reached on a machine which is running orders of magnitude slower than
usual, since each test usually runs in about 100-300 ms. Unfortunately,
sometimes our CI workers might get that slow.

This sparked a review of other usages of timeout contexts in other
tests, and all of them were increased to a minimum value of 1 minute,
under the rule of thumb that our tests will be more reliable on slow
machines if they "pass fast and fail slow".
