UpsertBindingRules RPC changed in eacecb8,
validation happens after the ID check now, because we don't want validation to
fail for update payloads which may contain incomplete objects.
API and RPC endpoints for ACLAuthMethods and ACLBindingRules should allow users
to send incomplete objects in order to, e.g., update single fields. This PR
provides "merging" functionality for these endpoints.
This PR tries to make API tests run fast, as an experiment to later apply
to all packages. Key changes include
- Swapping freeport for test/portal for port allocations
- Swappng some uses of WaitForResult with test/wait
- Turning on parallelism in api/testutil/slow.go
- Switching to custom public runner (32 vcpu)
There's also chunk of cleanup brought in for the ride
ACL binding rule create and deletes are always forwarded to the
authoritative region. In order to make these available in
federated regions, the leaders in these regions need to replicate
from the authoritative.
* basic-functionality demo for token CRUD
* Styling for tokens crud

* Delete method and associated serializer change
* Ability-checking for tokens
* Update policies acceptance tests to reflect new redirect rules
* Token ability unit tests
* Mirage config methods for token crud
* Token CRUD acceptance tests
* A couple visual diff snapshots
* Add and Delete abilities referenced for token operations
* Changing timeouts and adding a copy to clipboard action
* replaced accessor with secret when copying to clipboard
* PR comments addressed
* Simplified error passing for policy editor
This change add the RPC ACL binding rule handlers. These handlers
are responsible for the creation, updating, reading, and deletion
of binding rules.
The write handlers are feature gated so that they can only be used
when all federated servers are running the required version.
The HTTP API handlers and API SDK have also been added where
required. This allows the endpoints to be called from the API by users
and clients.
This change adds a new table that will store ACL binding rule
objects. The two indexes allow fast lookups by their ID, or by
which auth method they are linked to. Snapshot persist and
restore functionality ensures this table can be saved and
restored from snapshots.
In order to write and delete the object to state, new Raft messages
have been added.
All RPC request and response structs, along with object functions
such as diff and canonicalize have been included within this work
as it is nicely separated from the other areas of work.

If a plugin crashes quickly enough, we can get into a situation where the
deregister function is called before it's ever registered. Safely handle the
resulting nil pointer in the dynamic registry by not emitting a plugin event,
but also update the plugin event handler to tolerate nil pointers in case we
wire it up elsewhere in the future.
* artifact: enable inheriting environment variables from client
This PR adds client configuration for specifying environment variables that
should be inherited by the artifact sandbox process from the Nomad Client agent.
Most users should not need to set these values but the configuration is provided
to ensure backwards compatability. Configuration of go-getter should ideally be
done through the artifact block in a jobspec task.
e.g.
```hcl
client {
artifact {
set_environment_variables = "TMPDIR,GIT_SSH_OPTS"
}
}
```
Closes#15498
* website: update set_environment_variables text to mention PATH
This PR adds the client config option for turning off filesystem isolation,
applicable on Linux systems where filesystem isolation is possible and
enabled by default.
```hcl
client{
artifact {
disable_filesystem_isolation = <bool:false>
}
}
```
Closes#15496
This PR adds Merge() helper function for choosing which value of two pointers
to use during a larger merge operation.
If 'next' is not nil, use that value, otherwise use the 'previous' value.
* client: sandbox go-getter subprocess with landlock
This PR re-implements the getter package for artifact downloads as a subprocess.
Key changes include
On all platforms, run getter as a child process of the Nomad agent.
On Linux platforms running as root, run the child process as the nobody user.
On supporting Linux kernels, uses landlock for filesystem isolation (via go-landlock).
On all platforms, restrict environment variables of the child process to a static set.
notably TMP/TEMP now points within the allocation's task directory
kernel.landlock attribute is fingerprinted (version number or unavailable)
These changes make Nomad client more resilient against a faulty go-getter implementation that may panic, and more secure against bad actors attempting to use artifact downloads as a privilege escalation vector.
Adds new e2e/artifact suite for ensuring artifact downloading works.
TODO: Windows git test (need to modify the image, etc... followup PR)
* landlock: fixup items from cr
* cr: fixup tests and go.mod file
Streaming RPCs should only be registered once, not on every RPC call, because they set keys in StreamingRpcRegistry.registry map. This PR fixes it by checking whether endpoints are already registered before calling .register() method. Fixes#15474

Upcoming work to instrument the rate of RPC requests by consumer (and eventually
rate limit) require that we authenticate a RPC request before forwarding. Add a
new top-level `Authenticate` method to the server and have it return an
`AuthenticatedIdentity` struct. RPC handlers will use the relevant fields of
this identity for performing authorization.
This changeset includes:
* The main implementation of `Authenticate`
* Provide a new RPC `ACL.WhoAmI` for debugging authentication. This endpoint
returns the same `AuthenticatedIdentity` that will be used by RPC handlers. At
some point we might want to give this an equivalent HTTP endpoint but I didn't
want to add that to our public API until some of the other Workload Identity
work is solidified, especially if we don't need it yet.
* A full coverage test of the `Authenticate` method. This sets up two server
nodes with mTLS and ACLs, some tokens, and some allocations with workload
identities.
* Wire up an example of using `Authenticate` in the `Namespace.Upsert` RPC and
see how authorization happens after forwarding.
* A new semgrep rule for `Authenticate`, which we'll need to update once we're
ready to wire up more RPC endpoints with authorization steps.
This PR adds a fingerprinter to set the attribute
"plugins.cni.version.<name>" => "<version>"
for each CNI plugin in <client>.cni_path (/opt/cni/bin by default).

Nomad server components that aren't in the `nomad` package like the deployment
watcher and volume watcher need to make RPC calls but can't import the Server
struct to do so because it creates a circular reference. These components have a
"shim" object that gets populated to pass a "static" handler that has no RPC
context.
Most RPC handlers are never used in this way, but during server setup we were
constructing a set of static handlers for most RPC endpoints anyways. This is
slightly wasteful but also confusing to developers who end up being encouraged
to just copy what was being done for previous RPCs.
This changeset includes the following refactorings:
* Remove the static handlers field on the server
* Instead construct just the specific static handlers we need to pass into the
deployment watcher and volume watcher.
* Remove the unnecessary static handler from heartbeater
* Update various tests to avoid needing the static endpoints and have them use a
endpoint constructed on the spot.
Follow-up work will examine whether we can remove the RPCs from deployment
watcher and volume watcher entirely, falling back to raft applies like node
drainer does currently.
The `plugin status` command supports displaying CSI capabilities and topology
accessibility, but this was missing from the documentation. Extend the
`-verbose` example to show that info.
