* Reorder session authz checks
This implements a mechanism for service handlers to pass a repo
satisfying an interface into the scope IDs listing function. The purpose
of this interface is to allow the same function to perform authorization
checking against resources rather than requiring service handlers to
fetch all resources in the determined set of scopes and then perform
this checking. While this could be done in each service handler, this
approach centralizes the logic, which has the nice benefit of removing
some boilerplate from service handler list functions that have adapted
to it.
Tests haven't changed, which is expected -- the function should return
exactly what was being returned before, simply faster.
This updates the target resources to use a oneof for attributes. This
allows requests to the targets service to leverage the new
subtypes.AttributeTransformerInterceptor so that attributes are strongly
typed prior to the service handler.
This updates the credential library resources to use a oneof for
attributes. This allows requests to the credential library service to
leverage the new subtypes.AttributeTransformerInterceptor so that
attributes are strongly typed prior to the service handler.
This allows us to use SNI for actual host (e.g. routing) information. We
don't have the client cert yet so we can't look at that, so this
provides a way for us to convey the information needed to look up that
session's TLS stack.
Using SNI for hosts means we also run into the fact that we don't have
automatic agreement in terms of SANs. So when generating the certs we
now also pass worker address information to the function to be encoded
in the cert.
Finally, there is a change in how the websocket dialing happens, because
http.RoundTripper tries to be too clever for its own good and overwrites
NextProtos on a whim.
* fix(controller/targets): authorize-session should allow h_ ids
The targets controller previously only allowed hosts from a static catalog
since it checked for the ID subtype from the static package.
This change validates host ids with the plugin.Subtype as well
Fixes: #1850
* test: cover authorize-session with host id
Add a regression test to cover the case where an explicit host ID was
given when calling AuthorizeSession
Egress credentials Issued during AuthorizeSession are stored in the
session repo. These credentials are retrieved and stored in-memory on the
worker during the LookupSession call. Each proxy handler will need to
handle the credentials as required.
This test started failing when the order of the list response changed.
Since the order does not matter, this test was updated to not depend on
the order.
This change removes the hard-coded credential purpose for the Credential
Libraries. It also moves the logic of creating CredentialLibraries from
CredentialSources out of the repository and into the targets.Service.
This refactor will allow for additional credential purposes to be
supported in both the service and the repository.
For the target Repository's Create method, the options of
WithHostSources and WithCredentialSources where never used by the
targets.Service. As such the repository does not need to support these
options.
See: 51812ff779
Now that subtypes are registered via sub-packages, this TargetType is
not needed and should not be used. This removes it and updates the
target.Repository and targets.Service to use the updated code.
This was missed in eac433f7ff.
* refactor (controller): Use a grpc server for the grpc-gateway
This starts a grpc server for the grpc-gateway. The new gateway
server uses an in-memory listener which also supports "dialing", so
the http proxy can connect to the in-memory listener.
This change allows us to use all grpc server features and was in part
motivated by a need for an interceptor of inbound requests. With that
said, having a "proper" grpc server for the gateway will provide a lot
more flexibility and capabilities moving forward.
The request context will still be verified via middleware in the
http proxy (see wrapHandlerWithCommonFuncs). This verified context
will be serialized into a protobuf and sent along to the grpc-gateway
via metadata where an interceptor will add the verified request
info to the request's context (see requestCtxInterceptor). The
interceptor will verify the serialized request info via a shared ticket
with it's companion in-memory http proxy. FYI: the ticket is simply
random base62 string (see db.NewPrivateId).
This change also necessitated a minor change to services. We need to
return an empty response instead of nil, nil when there are no errors
and the response is empty.
* refactor (handlers): Rename gRPC Gateway filter
Originally, this was called an OutgoingInterceptor, which is an
unfortunate name since it's not an interceptor. Now that we're
refactoring the gateway stuff and have proper interceptors, renaming
this should remove ambiguity
* refactor: Rework how 204 with empty msg is handled
Recent changes to grpc gateway has necessitated a change to how
204s are handled by the gateway
* tests (bats): Check status codes for delete operations
This moves all of the tcp target functionality into a tcp package. It
also establishes a Register function in the target package to allow
specific target types to be registered at initilazation time. When
registering, a target type needs to provide its Subtype, as well as some
RepositoryHooks that are used by the target Repository.
* refact: Changes required for gorm v2
* refact: Add db.DB wrapper and refact all test fixtures to use it
Stop leaking the gorm abstraction within our unit tests.
* refact: Migrate direct calls to pq to pgx driver
The refactor will remove the remaining direct dependencies on
the pq driver which has been deprecated in favor of the pgx
driver.
It includes the addition of common.SqlOpen which is a wrapper around
sql.Open, which is needed to deal with the driver name changing from
"postgres" to "pgx" but in our code base the dialect and driver are
synonyms.
This adds a few command sketches but that's not the main point of the PR
and filling those out will come in a different PR. This adds a new flag
type that can combine inputs to a single target slice, retaining the
ability to distinguish where it came from but also keep ordering across
different flag names. It also implements a function that does the
heuristic parsing with fallback.
Added a new Endpoint struct at the top level host package level to capture host, set, and address chosen.
Temporarily add a host_plugin_host table to capture the hosts returned by the plugins. This ensures the datawarehouse is able to query the table to decide what host was chosen. The view used to update the datawarehouse dimension table provides rows with host set ids and hosts which are not in that host set. This is ok since the function which updates the dimension table provides the host set and host id chosen so that relationship doesn't need to be captured in the view itself.

* Remove Prefix Id and Plugin Name fields. Creating catalogs now require either the plugin id or the name of the plugin resource (but not both). Host Catalogs and Host Sets API resources now have a read only plugin field populated with plugin info. Host Catalogs have a plugin id field as a top level field.
* Create minimalistic plugin map and test plugin.
* Pass secrets and attributes to the plugin when creating catalogs or sets. Add tests for CreateSet and CreateCatalog repo methods.
* make fmt and extract out getPrivateCatalog and getCatalog helper methods.
* Exporting TestPluginServer so it can be used in the handlers.
* Keep separate persisted data from host catalogs lookups which facilitate passing it onto the plugins.
* Add TODO to merge get Catalog and get Persisted data.
* Adding tests for unimplemented being returned by the plugin.
* Use GetFields() instead of AsMap() to confirm attributes should be populated. Make clone consistent between catalog and sets.

The existing logic was to ignore Forbidden errors when recursively
listing in favor of looking for downstream scopes with appropriate
permissions. The problem is that when there is actually no
authentication token at all, what comes back is an Unauthenticated
error. Therefore if you didn't have permissions on the ingress scope
(e.g. the default of `global`) but did downstream for the anonymous
user, you'd get back an error.
I don't think there's any security issue with doing this; the user could
always have simply started the search at a downstream scope to begin
with so nothing more is being revealed, this just fixes behavior to
match expectations in this case.
A test was added for one of the services; the code is exactly the same
across them. The reason that the existing tests that were added with the
output fields testing didn't catch this is that even though they were
specifying `u_anon` as the user, the disabled test context skipped the
logic that would return a 401 in this case. It turns out that fixing
this is very complicated because we don't have a great way in most tests
of defining grants to put onto the generated scopes, so even if a true
anonymous context was added each test would require the anonymous user
to have list permissions on whatever resource was under test, requiring
a lot of role and grant and principal finagling. This is probably a good
longer-term TODO but not one that seemed worth it for this fix.
Fixes ICU-2301
This moves the generated pb files to the `sdk` module. This allows third parties to make use of them if desired (e.g. in upcoming plugins) and moves away from the `gen` nomenclature in the directory, since we are going to be adding some extra interface functions to the messages.
* refactor(worker): Move tcp_proxy into its own package
This refactors:
- the tcp_proxy.go into worker/proxy/tcp
- add a missing unit test for the HandleTcpProxyV1
- refactors session.go into worker/session, needed to avoid import cycle
- adds a baseline for a mock controller session client
- go lint fixes
* Add sleep between spinning listener goroutine and dialing

* use context where available when writing error events
* remove circular internal/errors pkg dep
* suppress some chatty errors using errors.WithoutEvent()
* convert auth oidc funcs to take context where needed to write events
