Nomad's periodic block includes a "time_zone" parameter which lets
operators set the time zone at which the next launch interval is
checked against. For this to work, Nomad needs to use the
"time.LoadLocation" which in-turn can use multiple TZ data sources.
When using the Docker image to trigger Nomad job registrations, it
currently does not have access to any TZ data, meaning it is only
aware of UTC. Adding the tzdata package contents to the release
image provides the required data for this to work.
It would have also been possible to set the "-tags" build tag when
releasing Nomad which would embed a copy of the timezone database
in the code. We decided against using the build tag approach as it
is a subtle way that we could introduce bugs that are very
difficult to track down and we prefer the commit approach.
In most RPC endpoints we use the resolved ACL object to determine whether a
given auth token or identity has access to the object of interest to the
RPC. In #15870 we adjusted this across most of the RPCs to handle workload identity.
But in the ACL endpoints that read policies, we can't use the resolved ACL
object and have to go back to the original token and lookup the policies it has
access to. So we need to resolve any workload-associated policies during that
lookup as well.

The test was incorrectly writing to state that registration had
been finished before writing the node identity token. This is the
opposite of what happens in the client code and caused a timing
issue which meant we read registration as completed before we had
the identity available and therefore returned the secret ID.
In Nomad Enterprise we can fingerprint multiple Consul datacenters. If neither
is `"default"` then we end up with warning logs about adding a "link".
The `Link` field on the `Node` struct is a map of attributes that only
contributes to the node's computed hash. The `"consul"` key's value is derived
from the `unique.consul.name` attribute, which only exists if there's a default
Consul cluster.
Update the fingerprint to skip setting the link field if there's no
`unique.consul.name`, and lower the warning log for malformed fields to debug;
this is a minor scheduling optimization largely captured by existing Consul
fields in the node computed class. The only reason not to remove it entirely is
to avoid changing computed classes on existing large clusters.

On Windows, the `os.Process.Signal` method returns an error when sending
`os.Interrupt` (SIGINT) because it isn't implemented. This causes test servers
in the `testutil` packages to break on Windows. Use the platform specific
syscalls to generate the SIGINT instead.
The agent's signal handler also did not correctly handle the Ctrl-C because we
were masking os.Interrupt instead of SIGINT.

When calling the client identity renew API, it is possible the
target node ID is provided by either the URI or within the request
body. This change fixes a bug where all calls using a node_id query
parameter would be reject as it failed to decode the empty request
body.

The metrics on the eval broker include labels for the job ID, but under a high
volume of dispatch workloads, this results in excessive heap usage on the
leader. Dispatch workloads should use their parent ID rather than their child ID
for any metrics we collect.
Also, eliminate an extra copy of the labels. And remove the extremely high
cardinality `"eval_id"` label from the `nomad.broker.eval_waiting` metric.

The allocation network hook was not properly restoring network status from state when the network had previously been setup. This led to missing environment variables, misconfigured hosts file, and resolv.conf when a task was restarted after the nomad agent has restarted.

When checking if the target path is within the root path, the
target path is trimmed and then file information is fetched. If
the trimmed path does not exist, then the full target path is
not within the root. In the case of receiving a not exist error,
simply return false.

A small optimization in the scheduler required users to specify specific
models of devices if the required count was higher than the individual
model/vendor on the node. This change removes that optimization to allow
for more intuitive device scheduling when different vendor/model device
types exist on a node.
The `go-getter` update in https://github.com/hashicorp/nomad/pull/26713 is not passing tests upstream (apparently https://github.com/hashicorp/go-getter/pull/548 is the origin of the problem but that PR did not ever run tests). The issue being fixed isn't a critical vulnerability, so in the interest of preparing us for the next release, revert the `go-getter` change but keep the Go toolchain update.
We'll skip go-getter 1.8.0 and pick up the next patch version once its issues are fixed.

setting the delay lower will (hopefully) keep within the job timeout.
I'm not sure why the `pledge` task apparently flakes like this;
I could find no useful info in the logs.
When configuring Nomad Enterprise with Consul Enterprise and multiple
namespaces, you need to include the `consul_namespace` mapping in the auth
method configuration. Otherwise you'll see an error like "unknown variable
accessed: value.consul_namespace". There's no example of the updated auth method
configuration you need, which makes this detail unclear when we're showing the
claim being used in the following `consul acl auth-method create` command.
During a large volume dispatch load test, I discovered that a lot of the total
scheduling time is being spent calling `structs.ParsePortRanges` repeatedly, in
order to parse the reserved ports configuration of the node (ex. converting
`"80,8000-8001"` to `[]int{80, 8000, 8001}`). A close examination of the
profiles shows that the bulk of the time is being spent hashing the keys for the
map of ports we use for de-duplication, and then sorting the resulting slice.
The `(*NetworkIndex) SetNode` method that calls the offending `ParsePortRanges`
merges all the ports into the `UsedPorts` map of bitmaps at scheduling
time. Which means the consumer of the slice is already de-duplicating and
doesn't care about the order. The only other caller of `ParsePortRanges` is when
we validate the configuration file, and that throws away the slice entirely.
By skipping de-duplication and not sorting, we can cut down the runtime of this
function by 30x and memory usage by 3x.
