This changeset includes some additional unit tests for secure
variables ACL policies, so that we have explicit coverage of edge
cases we're discussing with the UI folks.
Adds a new policy block inside namespaces to control access to secure
variables on the basis of path, with support for globbing.
Splits out VerifyClaim from ResolveClaim.
The ServiceRegistration RPC only needs to be able to verify that a
claim is valid for some allocation in the store; it doesn't care about
implicit policies or capabilities. Split this out to its own method on
the server so that the SecureVariables RPC can reuse it as a separate
step from resolving policies (see next commit).
Support implicit policies based on workload identity
Improve how the all namespaces wildcard (`*`) is handled when checking
ACL permissions. When using the wildcard namespace the `AllowNsOp` would
return false since it looks for a namespace called `*` to match.
This commit changes this behavior to return `true` when the queried
namespace is `*` and the token allows the operation in _any_ namespace.
Actual permission must be checked per object. The helper function
`AllowNsOpFunc` returns a function that can be used to make this
verification.
Add new namespace ACL requirement for the /v1/jobs/parse endpoint and
return early if HCLv2 parsing fails.
The endpoint now requires the new `parse-job` ACL capability or
`submit-job`.

Fix a bug where a millicious user can access or manipulate an alloc in a
namespace they don't have access to. The allocation endpoints perform
ACL checks against the request namespace, not the allocation namespace,
and performs the allocation lookup independently from namespaces.
Here, we check that the requested can access the alloc namespace
regardless of the declared request namespace.
Ideally, we'd enforce that the declared request namespace matches
the actual allocation namespace. Unfortunately, we haven't documented
alloc endpoints as namespaced functions; we suspect starting to enforce
this will be very disruptive and inappropriate for a nomad point
release. As such, we maintain current behavior that doesn't require
passing the proper namespace in request. A future major release may
start enforcing checking declared namespace.
This adds an initial implementation of ACLs for HostVolumes.
Because HostVolumes are a cluster-wide resource, they cannot be tied to
a namespace, thus here we allow similar wildcard definitions based on
their names, tied to a set of capabilities.
Initially, the only available capabilities are deny, or mount. These
may be extended in the future to allow read-fs, mount-readonly and
similar capabilities.
This adds `alloc-exec` capability to allow operator to execute command into a
running task. Furthermore, it adds `alloc-node-exec` capability, required when
the alloc task is raw_exec or a driver with no FSIsolation.
This capability will gate access to features that allow interacting with
a running allocation, for example, signalling, stopping, and rescheduling
specific allocations.
This commit adds basic support for globbing namespaces in acl
definitions.
For concrete definitions, we merge all of the defined policies at load time, and
perform a simple lookup later on. If an exact match of a concrete
definition is found, we do not attempt to resolve globs.
For glob definitions, we merge definitions of exact replicas of a glob.
When loading a policy for a glob defintion, we choose the glob that has
the closest match to the namespace we are resolving for. We define the
closest match as the one with the _smallest character difference_
between the glob and the namespace we are matching.
