As part of the work for 1.7.0 we moved portions of the task cgroup setup down
into the executor. This requires that the executor constructor get the
`TaskConfig.Resources` struct, and this was missing from the `qemu` driver. We
fixed a panic caused by this change in #19089 before we shipped, but this fix
was effectively undo after we added plumbing for custom cgroups for `raw_exec`
in 1.8.0. As a result, running `qemu` tasks always fail on Linux.
This was undetected in testing because our CI environment doesn't have QEMU
installed. I've got all the unit tests running locally again and have added QEMU
installation when we're running the drivers tests.

Trusted Supply Chain Component Registry (TSCCR) enforcement starts Monday and an
internal report shows our semgrep action is pinned to a version that's not
currently permitted. Update all the action versions to whatever's the new
hotness to maximum the time-to-live on these until we have automated pinning
setup.
Also version bumps our chromedriver action, which randomly broke upstream today.
so in enterprise we can use Vault for secrets,
without merge conflicts from oss->ent.
also:
* use hashicorp/setup-golang
* setup-js for self-hosted runners
they don't come with yarn, nor chrome,
and might not always match node version.
Some of the paths ignored by `test-core.yaml` need to be checked by
`make check`. The `checks.yaml` workflow run on these paths and can also
be used as a reusable workflow.
namely, these workflows:
test-e2e, test-ui, and test-windows
extra-curricularly, as part of the overall
migration effort company-wide, this also includes
some standardization such as:
* explicit permissions:read on various workflows
* pinned action version shas (per https://github.com/hashicorp/security-public-tsccr)
* actionlint, which among other things runs
shellcheck on GHA run steps

Running tests `on: push` prevents GitHub from showing the workflow approval
button, which prevents tests from being run on community-contributed (or even
just non-Nomad HashiCorp folks) PRs. Running `on: pull_request` automatically
picks up opened, reopened, and synchronize hooks (where "synchronize" means a
push to HEAD on the PR's branch, so that'll pick up rebases and updates).
But we also want to run tests on `main` and the various `release` backport
branches, so retain a `on: push` for those.
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
This PR changes test-core to make use of
https://github.com/hashicorp/setup-golang
to consolidate the setting up of the Go compiler and the Go modules cache
used for the CI job.

The `hc-install` tool we're using needed a patch for a specific bug, but that's
since been merged. We definitely want to switch to using a standard release from
that project once one is shipped with the CLI, but pinning to HEAD should keep
us for now.
This PR update to Go 1.18.2. Also update the versions of hclfmt
and go-hclogfmt which includes newer dependencies necessary for dealing
with go1.18.
The hcl v2 branch is now 'nomad-v2.9.1+tweaks2', to include a fix for
newer macOS versions: 8927e75e82
This PR adds support for the raw_exec driver on systems with only cgroups v2.
The raw exec driver is able to use cgroups to manage processes. This happens
only on Linux, when exec_driver is enabled, and the no_cgroups option is not
set. The driver uses the freezer controller to freeze processes of a task,
issue a sigkill, then unfreeze. Previously the implementation assumed cgroups
v1, and now it also supports cgroups v2.
There is a bit of refactoring in this PR, but the fundamental design remains
the same.
Closes#12351#12348
test_checks.sh was removed in 2019 and now just breaks if VERBOSE is
set when running tests via make targets
in GHA, use verbose mode to display what tests are running
This PR introduces support for using Nomad on systems with cgroups v2 [1]
enabled as the cgroups controller mounted on /sys/fs/cgroups. Newer Linux
distros like Ubuntu 21.10 are shipping with cgroups v2 only, causing problems
for Nomad users.
Nomad mostly "just works" with cgroups v2 due to the indirection via libcontainer,
but not so for managing cpuset cgroups. Before, Nomad has been making use of
a feature in v1 where a PID could be a member of more than one cgroup. In v2
this is no longer possible, and so the logic around computing cpuset values
must be modified. When Nomad detects v2, it manages cpuset values in-process,
rather than making use of cgroup heirarchy inheritence via shared/reserved
parents.
Nomad will only activate the v2 logic when it detects cgroups2 is mounted at
/sys/fs/cgroups. This means on systems running in hybrid mode with cgroups2
mounted at /sys/fs/cgroups/unified (as is typical) Nomad will continue to
use the v1 logic, and should operate as before. Systems that do not support
cgroups v2 are also not affected.
When v2 is activated, Nomad will create a parent called nomad.slice (unless
otherwise configured in Client conifg), and create cgroups for tasks using
naming convention <allocID>-<task>.scope. These follow the naming convention
set by systemd and also used by Docker when cgroups v2 is detected.
Client nodes now export a new fingerprint attribute, unique.cgroups.version
which will be set to 'v1' or 'v2' to indicate the cgroups regime in use by
Nomad.
The new cpuset management strategy fixes#11705, where docker tasks that
spawned processes on startup would "leak". In cgroups v2, the PIDs are
started in the cgroup they will always live in, and thus the cause of
the leak is eliminated.
