* Minor test fixes
The auth rotation test fix allows us to keep checking if we did not yet
see the expected bytes in case the call to lookup succeeds but we are
late in rotating due to parallelism.
The api credentials test fix allows us to check if at _least_ one
rotation has happened. That way if two rotations happen before we check
again due to parallelism, this is deemed a successful result.
* Add timeout to auth rotation test
The nhooyr/websocket library now has a release with the new default
behavior that removes the message size limit. This allows us to switch
off of the fork and back to the upstream.
In the same release that includes the fix we need for the boundary
client, the wspb helper package was removed from websocket. This package
contained some functions to read and write protobuf messages. However,
it was using the deprecated github.com/golang/protobuf/proto library. To
avoid this dependancy in the library they opted to just remove wspb.
Thus this provides a replacement implementation that uses
google.golang.org/protobuf/proto. Notably the newer proto library seems
to lack an equivalent of proto.NewBuffer so writes to the websocket and
not able to leverage a sync.Pool of byte.Buffers to reduce allocations.

* fix: monitorUpstreamConnectionState CPU consumption
`monitorUpstreamConnectionState()` is a goroutine that listens for GRPC client connection changes using GRPC's `WaitForStateChange` method. `monitorUpstreamConnectionState()` was consuming the a lot of CPU. It was continuously running and not actually waiting for state changes. The `state` for `monitorUpstreamConnectionState()` was not getting correctly updated which caused the loop to continuously run instead of waiting for new state changes.
Update GRPC `WaitForStateChange` method to use the same `state` that gets updated.
In preparation for putting proxy code in the api package this creates some necessary fields in the target output and it pre-moves credential parsing and proxy handshake code to their new places. This will make the diff for the actual proxy code move quite a bit smaller.

With a suitably slow system -- say, if you're waiting on a Windows
Terminal to output text inside a virtual machine -- the expected order
of things can be thrown off. One specific way this can happen is that
the worker can attempt to dial and have its dial fail because of the
slowness causing the dial context to time out. If, because of the
slowness, we also haven't released the log gate yet, then the event with
the failure information will be queued, along with the context that was
used.
Unfortunately, in some of these error cases, the context that was used
was the dial context instead of the system base context. In many other
places in the function it was the system base context so this is just a
mismatch, probably from code written at different times.
Normally this wouldn't be a problem as we'd fall back to the underlying
logger, but when we release the log gate, things happen differently:
it's a synchronous function and on error it causes us to abandon
system startup entirely.
This commit fixes the issue with using the incorrect context. It's an
open question whether we should change the behavior around errors when
replaying queued events, falling back to the underlying logger instead
of erroring.
* fix (events): convert multierror to stdlib error
multierror errors will be converted to a stdlib error (because
multierror doesn't support json marshaling).
* refact (errors): convert from multierror to stdlib errors.Join(...)
* refact: convert from pkg/errors to stdlib error wrapping
* feat: Worker Connectivity Health Check
Add worker upstream connection state. API calls to the worker's ops `/heath?worker_info=1` endpoint should now return a new filed called `upstream_connection_state`
```
{
"worker_process_info":{
"state":"active",
"active_session_count":0,
"upstream_connection_state":"READY"
}
}
```
The states returned will be GRPC connection states: https://grpc.github.io/grpc/core/md_doc_connectivity-semantics-and-api.html
There could be multiple upstream addresses but GRPC manual resolver determines the state of the connection.
* Adding explicit MPL license for sub-package.
This directory and its subdirectories (packages) contain files licensed with the MPLv2 `LICENSE` file in this directory and are intentionally licensed separately from the BSL `LICENSE` file at the root of this repository.
* Adding explicit MPL license for sub-package
This directory and its subdirectories (packages) contain files licensed with the MPLv2 `LICENSE` file in this directory and are intentionally licensed separately from the BSL `LICENSE` file at the root of this repository.
* Updating the license from MPL to Business Source License
Going forward, this project will be licensed under the Business Source License v1.1. Please see our blog post for more details at https://hashi.co/bsl-blog, FAQ at www.hashicorp.com/licensing-faq, and details of the license at www.hashicorp.com/bsl.
* Update copyright file headers to BUS-1.1
* Rerun make gen
This will pick up the last of the license changes
* Revert "Rerun make gen"
This reverts commit dbe0968bffd92745d8663c6940debae098395a6b.
* Remove copywrite from generation script
The current version of copywrite is not sophisticated enough
to only apply the copywrite changes to certain subdirectories,
so to avoid accidentally relicensing our api and sdk modules,
we will stop running the copywrite script until such time
that it can do the right thing.
* License protobuf API as MPL
The protobuf API files are used to generate the SDK,
since we want the SDK to be MPL, the protobuf files
must also be MPL. This extends to all protobuf files
whose sources end up in the SDK directory, including:
- internal/proto/controller/api
- internal/proto/controller/custom_options
- internal/proto/plugin
It also includes the generated service directory in
internal/gen/controller/api/services, since they are
generated from the protobuf sources used for the SDK.
* Change website license file name
This makes the naming scheme consistent with the rest
of the repository.
* Add note on licensing to README
* Set copywrite license to BUSL
* Revert "Add note on licensing to README"
This reverts commit 4d865a91a7a4f11605f0dc4609355d7e3c3cfffe.

Most of the changes here are changes or enhancements that are useful for
tests. The crux of the issue was that I had pulled up one var to the
package level so it could be read from tests, but that var was not being
reset between tests. It's not even used in tests anymore, so I put it
back to function-local.
* Add more logging to worker auth rotation and test flags
This makes it much easier to figure out when and why rotation is
happening and control it for tests/debugging.
* Update auth rotation logic
Because we were looking at validity period of client certs, which may
not have matched the actual rotation interval, it was possible (mostly
in test scenarios) for the rotation to happen multiple times on the
roots before we actually hit the worker rotation interval.
This changes how the interval is calculated by looking at the difference
between not-after values on the certs to understand the rotation
interval being used by the controller. We then use that as the starting
point for calculating a next-rotation time.
This makes it much easier to figure out when and why rotation is
happening and control it for tests/debugging.
Remove cert skew
Cherry-picked from release/0.12.x
Do not allow PKI-KMS workers to have names updated via API
This would cause their public IDs to change, which we do not want.
Descriptions are also disallowed, since those come from the config file.
This also adds logic to allow upgrading from old KMS method to new, with
a test.

This adds a new mechanism for worker authentication that uses the
third-party arbitration of the original KMS flow by leveraging
recently-added capabilities in nodeenrollment to support a registration
wrapper. This allows for workers to be registered to the system with
just a name and a matching wrapper, while at the same time allowing
these workers to be used for private Vault access and multi-hop as they
contain per-worker encryption keys and support rotation.
Nodes using this mode will generate and rotate credentials in-memory
(using another recently added nodeenrollment capability) so will have a
new set of keys on every startup. This has the side effect of ensuring
that there is never a conflict or re-use of these credentials.
Note that the normal test worker flow was using the now-deprecated KMS
method; there is still a test that uses this (explicitly) but all other
tests using test workers that did not specify a specific PKI flow now
actually use this mechanism. This means there is fairly decent test
coverage in a general sense, plus the specific tests updated/added for
this feature.
This also adds a new KMS type that can be used to have
distinct KMSes for upstream authentication vs. accepting from
downstream.
When possible downstream workers will include their worker id information in
the connections they establish with the upstream using the nodeenrollment
library. The tracking listener now tracks connections that are connected in
this same way instead of just connections of type *tls.Conn.
This commit replaces `os.MkdirTemp` with `t.TempDir` in tests. The
directory created by `t.TempDir` is automatically removed when the test
and all its subtests [complete.
Prior to this commit, temporary directory created using `os.MkdirTemp`
needs to be removed manually by calling `os.RemoveAll`, which is omitted
in some tests. The error handling boilerplate e.g.
defer func() {
if err := os.RemoveAll(dir); err != nil {
t.Fatal(err)
}
}
is also tedious, but `t.TempDir` handles this for us nicely.

* Fix target port handling
This fixes two issues that compounded on each other (see the Changelog
update for more information):
* The verification logic for hosts was not correct for update operations
(in multiple ways) which meant that a host could be updated after
creation to have a port. Targets had a previously fixed bug where they
did not require a default port, which meant that ports could be used
from hosts
* A recent (unreleased) change had prioritized any port coming from the
host over the default port, which would mean there was no way if a
host had a port specified to use it in multiple targets.
This fixes the update verification logic, and strikes a middle ground
between breaking things and not by allowing existing addresses with
ports to be used with targets but ignoring that port, instead requiring
targets to have default port set at authorize time (currently there is
backwards compat that does not require this due to the original optional
port bug).
* Update CHANGELOG.md
