Some Nomad users ship application logs out-of-band via syslog. For these users
having `logmon` (and `docker_logger`) running is unnecessary overhead. Allow
disabling the logmon and pointing the task's stdout/stderr to /dev/null.
This changeset is the first of several incremental improvements to log
collection short of full-on logging plugins. The next step will likely be to
extend the internal-only task driver configuration so that cluster
administrators can turn off log collection for the entire driver.

PR #14492 introduced a new check to return 0 when the `nomad job plan`
command returns a diff of type `None`.
But the `-diff` CLI flag was also being used to control whether the plan
request should return the diff of not instead of just controlling if the
diff was printed.
This means that when `-diff=false` is set the response does not include
any diff information, and so the new check panics.
This commit fixes the problem by always requesting a diff and using the
`-diff` only for controlling output, as it's currently documented.

Adds a new configuration to clients to optionally allow them to drain their
workloads on shutdown. The client sends the `Node.UpdateDrain` RPC targeting
itself and then monitors the drain state as seen by the server until the drain
is complete or the deadline expires. If it loses connection with the server, it
will monitor local client status instead to ensure allocations are stopped
before exiting.
If an allocation is slow to stop because of `kill_timeout` or `shutdown_delay`,
the node drain is marked as complete prematurely, even though drain monitoring
will continue to report allocation migrations. This impacts the UI or API
clients that monitor node draining to shut down nodes.
This changeset updates the behavior to wait until the client status of all
drained allocs are terminal before marking the node as done draining.

The first start of a Consul Connect proxy sidecar triggers a run
of the envoy_version hook which modifies the task config image
entry. The modification takes into account a number of factors to
correctly populate this. Importantly, once the hook has run, it
marks itself as done so the taskrunner will not execute it again.
When the client receives a non-destructive update for the
allocation which the proxy sidecar is a member of, it will update
and overwrite the task definition within the taskerunner. In doing
so it overwrite the modification performed by the hook. If the
allocation is restarted, the envoy_version hook will be skipped as
it previously marked itself as done, and therefore the sidecar
config image is incorrect and causes a driver error.
The fix removes the hook in marking itself as done to the view of
the taskrunner.
* api: enable support for setting original source alongside job
This PR adds support for setting job source material along with
the registration of a job.
This includes a new HTTP endpoint and a new RPC endpoint for
making queries for the original source of a job. The
HTTP endpoint is /v1/job/<id>/submission?version=<version> and
the RPC method is Job.GetJobSubmission.
The job source (if submitted, and doing so is always optional), is
stored in the job_submission memdb table, separately from the
actual job. This way we do not incur overhead of reading the large
string field throughout normal job operations.
The server config now includes job_max_source_size for configuring
the maximum size the job source may be, before the server simply
drops the source material. This should help prevent Bad Things from
happening when huge jobs are submitted. If the value is set to 0,
all job source material will be dropped.
* api: avoid writing var content to disk for parsing
* api: move submission validation into RPC layer
* api: return an error if updating a job submission without namespace or job id
* api: be exact about the job index we associate a submission with (modify)
* api: reword api docs scheduling
* api: prune all but the last 6 job submissions
* api: protect against nil job submission in job validation
* api: set max job source size in test server

new WaitForPlugin() called during csiHook.Prerun,
so that on startup, clients can recover running
tasks that use CSI volumes, instead of them being
terminated and rescheduled because they need a
node plugin that is "not found" *yet*, only because
the plugin task has not yet been recovered.
The `ephemeral_disk` block's `migrate` field allows for best-effort migration of
the ephemeral disk data to new nodes. The documentation says the `migrate` field
is only respected if `sticky=true`, but in fact if client ACLs are not set the
data is migrated even if `sticky=false`.
The existing behavior when client ACLs are disabled has existed since the early
implementation, so "fixing" that case now would silently break backwards
compatibility. Additionally, having `migrate` not imply `sticky` seems
nonsensical: it suggests that if we place on a new node we migrate the data but
if we place on the same node, we throw the data away!
Update so that `migrate=true` implies `sticky=true` as follows:
* The failure mode when client ACLs are enabled comes from the server not passing
along a migration token. Update the server so that the server provides a
migration token whenever `migrate=true` and not just when `sticky=true` too.
* Update the scheduler so that `migrate` implies `sticky`.
* Update the client so that we check for `migrate || sticky` where appropriate.
* Refactor the E2E tests to move them off the old framework and make the intention
of the test more clear.
Requests without an ACL token that pass thru the client's HTTP API are treated
as though they come from the client itself. This allows bypass of ACLs on RPC
requests where ACL permissions are checked (like `Job.Register`). Invalid tokens
are correctly rejected.
Fix the bypass by only setting a client ID on the identity if we have a valid node secret.
Note that this changeset will break rate metrics for RPCs sent by clients
without a client secret such as `Node.GetClientAllocs`; these requests will be
recorded as anonymous.
Future work should:
* Ensure the node secret is sent with all client-driven RPCs except
`Node.Register` which is TOFU.
* Create a new `acl.ACL` object from client requests so that we
can enforce ACLs for all endpoints in a uniform way that's less error-prone.~
This update changes the behaviour when following logs from an
allocation, so that both stdout and stderr files streamed when the
operator supplies the follow flag. The previous behaviour is held
when all other flags and situations are provided.

When we added recovery of pause containers in #16352 we called the recovery
function from the plugin factory function. But in our plugin setup protocol, a
plugin isn't ready for use until we call `SetConfig`. This meant that
recovering pause containers was always done with the default
config. Setting up the Docker client only happens once, so setting the wrong
config in the recovery function also means that all other Docker API calls will
use the default config.
Move the `recoveryPauseContainers` call into the `SetConfig`. Fix the error
handling so that we return any error but also don't log when the context is
canceled, which happens twice during normal startup as we fingerprint the
driver.
Currently, the `exec` driver is only setting the Bounding set, which is
not sufficient to actually enable the requisite capabilities for the
task process. In order for the capabilities to survive `execve`
performed by libcontainer, the `Permitted`, `Inheritable`, and `Ambient`
sets must also be set.
Per CAPABILITIES (7):
> Ambient: This is a set of capabilities that are preserved across an
> execve(2) of a program that is not privileged. The ambient capability
> set obeys the invariant that no capability can ever be ambient if it
> is not both permitted and inheritable.
* client/fingerprint: correctly fingerprint E/P cores of Apple Silicon chips
This PR adds detection of asymetric core types (Power & Efficiency) (P/E)
when running on M1/M2 Apple Silicon CPUs. This functionality is provided
by shoenig/go-m1cpu which makes use of the Apple IOKit framework to read
undocumented registers containing CPU performance data. Currently working
on getting that functionality merged upstream into gopsutil, but gopsutil
would still not support detecting P vs E cores like this PR does.
Also refactors the CPUFingerprinter code to handle the mixed core
types, now setting power vs efficiency cpu attributes.
For now the scheduler is still unaware of mixed core types - on Apple
platforms tasks cannot reserve cores anyway so it doesn't matter, but
at least now the total CPU shares available will be correct.
Future work should include adding support for detecting P/E cores on
the latest and upcoming Intel chips, where computation of total cpu shares
is currently incorrect. For that, we should also include updating the
scheduler to be core-type aware, so that tasks of resources.cores on Linux
platforms can be assigned the correct number of CPU shares for the core
type(s) they have been assigned.

When a disconnect client reconnects the `allocReconciler` must find the
allocations that were created to replace the original disconnected
allocations.
This process was being done in only a subset of non-terminal untainted
allocations, meaning that, if the replacement allocations were not in
this state the reconciler didn't stop them, leaving the job in an
inconsistent state.
This inconsistency is only solved in a future job evaluation, but at
that point the allocation is considered reconnected and so the specific
reconnection logic was not applied, leading to unexpected outcomes.
This commit fixes the problem by running reconnecting allocation
reconciliation logic earlier into the process, leaving the rest of the
reconciler oblivious of reconnecting allocations.
It also uses the full set of allocations to search for replacements,
stopping them even if they are not in the `untainted` set.
The system `SystemScheduler` is not affected by this bug because
disconnected clients don't trigger replacements: every eligible client
is already running an allocation.
Implement the new `nomad job restart` command that allows operators to
restart allocations tasks or reschedule then entire allocation.
Restarts can be batched to target multiple allocations in parallel.
Between each batch the command can stop and hold for a predefined time
or until the user confirms that the process should proceed.
This implements the "Stateless Restarts" alternative from the original
RFC
(https://gist.github.com/schmichael/e0b8b2ec1eb146301175fd87ddd46180).
The original concept is still worth implementing, as it allows this
functionality to be exposed over an API that can be consumed by the
Nomad UI and other clients. But the implementation turned out to be more
complex than we initially expected so we thought it would be better to
release a stateless CLI-based implementation first to gather feedback
and validate the restart behaviour.

Fixes#16517
Given a 3 Server cluster with at least 1 Client connected to Follower 1:
If a NodeMeta.{Apply,Read} for the Client request is received by
Follower 1 with `AllowStale = false` the Follower will forward the
request to the Leader.
The Leader, not being connected to the target Client, will forward the
RPC to Follower 1.
Follower 1, seeing AllowStale=false, will forward the request to the
Leader.
The Leader, not being connected to... well hoppefully you get the
picture: an infinite loop occurs.

* services: always set deregister flag after deregistration of group
This PR fixes a bug where the group service hook's deregister flag was
not set in some cases, causing the hook to attempt deregistrations twice
during job updates (alloc replacement).
In the tests ... we used to assert on the wrong behvior (remove twice) which
has now been corrected to assert we remove only once.
This bug was "silent" in the Consul provider world because the error logs for
double deregistration only show up in Consul logs; with the Nomad provider the
error logs are in the Nomad agent logs.
* services: cleanup group service hook tests
In #16217 we switched clients using Consul discovery to the `Status.Members`
endpoint for getting the list of servers so that we're using the correct
address. This endpoint has an authorization gate, so this fails if the anonymous
policy doesn't have `node:read`. We also can't check the `AuthToken` for the
request for the client secret, because the client hasn't yet registered so the
server doesn't have anything to compare against.
Instead of hitting the `Status.Peers` or `Status.Members` RPC endpoint, use the
Consul response directly. Update the `registerNode` method to handle the list of
servers we get back in the response; if we get a "no servers" or "no path to
region" response we'll kick off discovery again and retry immediately rather
than waiting 15s.
