* hcl2template: pass user variable values to plugins as packer_user_variables (#13686)
HCL2 builds do not send the packer_user_variables config key to the
builder, provisioner and post-processor plugins. Legacy JSON builds
send this key (through CoreBuild.packerConfig()). Without the key, the
plugin SDK keeps interpolate.Context.UserVariables nil. Then the
template function {{ user "name" }} fails with 'error calling user:
test'. This failure occurs in each string that a plugin interpolates at
run time, for example the contents of the vagrant post-processor's
vagrantfile_template.
Add the function PackerConfig.userVariableValues(). This function
converts the input variable values to strings, equivalent to the legacy
user variables. The core sends the map at each plugin handoff point:
builder, provisioner, post-processor, and enforced provisioner.
The map does not contain the sensitive variables. A sensitive value
goes to a plugin only if the template refers to it explicitly. The map
does not contain values that are not primitive (lists, maps, objects).
Legacy user variables were always strings.

* plugin-getter: install plugins from non-GitHub HTTP sources (#13691)
Packer can only install plugins from github.com, with
releases.hashicorp.com consulted first for HashiCorp-published plugins.
This has been a long-standing gap for air-gapped and policy-restricted
environments (#11164): the source address parser already accepts any
hostname, but both existing getters reject non-github.com sources at
install time.
Add a remote plugin getter that installs plugins from the host named in
a required_plugins source address. The host serves the directory
structure of releases.hashicorp.com under the source's path: an
index.json listing versions, and per version a SHA256SUMS file, the
zips it lists, and - when the zip names carry no plugin protocol
version - the version's manifest.json. A plugin published on
releases.hashicorp.com is therefore mirrored as a verbatim copy of its
tree, with every checksum file and signature upstream-authored. A
plugin published as GitHub release assets is mirrored by copying each
release's assets into a version directory, renaming their SHA256SUMS
file to the unprefixed convention with content unchanged, and writing
an index.json listing the versions. Both kinds of content can be
served side by side by one host.
Getter selection happens per source address: github.com sources keep
the release and github getters unchanged, while any other host is
served by the remote getter over HTTPS. Sources with three or more
components are supported, up to the existing 16-component limit, so
nested artifact-repository paths and hosts that embed the upstream
origin in their path all resolve.
Version discovery, constraint solving, checksum verification, and the
binary naming rules match the existing getters. The installed filename
is rebuilt from validated checksum-file fields and never taken from the
server's response, checksum entries matching neither known naming shape
are rejected rather than guessed at, and nothing the remote metadata
supplies is used to fetch from another origin or path. index.json
parsing is covered by fixtures captured from the live releases API, so
a format change there fails tests rather than user installs.

* feat(provenance): add SLSA provenance and attestation signing libraries
Add internal/provenance for deriving in-toto subjects from Packer
artifacts, building SLSA Provenance v1 predicates, wrapping in-toto
statements, and best-effort git/CI source detection.
Add internal/attestation for DSSE envelope handling and a pluggable
Signer/Verifier backend supporting key (local PEM), kms (aws/gcp/
azure/hashivault), and keyless (Sigstore Fulcio) modes, plus Sigstore
bundle handling and DSSE/policy verification.
Add the supporting module dependencies in go.mod/go.sum.
* feat(provenance): add provenance post-processor
Add the opt-in "provenance" post-processor that runs after a build,
derives subjects from the artifact, emits DSSE-wrapped SLSA provenance
(and optional SBOM) attestations, signs them via the configured
signing backend, and writes sidecar files (including *.sigstore.json
bundles in keyless mode). Register it in the core post-processor set.
The provenance enable flag is a tri-state so an unset value stays
enabled through HCL2 decoding instead of being silently disabled.
* feat(provenance): add verify-attestation command
Add "packer verify-attestation" to verify signed DSSE attestations
against key, KMS, and keyless policy inputs, including optional
Sigstore bundle checks for Rekor and timestamp evidence. Register the
command in the CLI.
* docs(provenance): add reference CI workflows and changelog
Add reference GitHub Actions workflows under examples/ci for SLSA L2
keyless signing and L3-compatible delegated signing
* fix: lint and tests
* Added docs for Provenance PostProcessor
Prevents unnecessary update operations by checking if the
bucket's description and labels already match the requested
values before issuing an update.
Improves efficiency and avoids redundant API calls.

- Modify GetCoreBuildProvisionerFromBlock to accept build name for overrides.
- Add tests for FetchEnforcedBlocks to ensure correct behavior and error handling.
- Implement diagnostics for unsupported legacy JSON templates.
* Implement enforced provisioner parsing and handling
- Introduced a new package `enforcedparser` to handle parsing of enforced provisioner blocks from HCL and JSON formats.
- Refactored existing code to utilize the new `ParseProvisionerBlocks` function from the `enforcedparser` package.
- Updated `GetCoreBuildProvisionerFromEnforcedBlock` method to convert enforced provisioner blocks into core build provisioners.
- Enhanced error handling and logging during the parsing process.
- Added tests for the new parsing functionality and ensured existing tests were updated to reflect changes.
- Modified `InjectEnforcedProvisioners` method in JSON registry to utilize the new parsing logic.

It was possible to put the same source 2 times in the build and when
using HCP, it would error eventually since they are considered the same
build from HCP side
As the rest of the build process was updated to remove references to the
Build interface exposed by the SDK, we change the usage of such types in
the hcp internal package, so they are typed with *CoreBuild too.
Since the protos for uploading an SBOM for a build have been changed to
use an enumeration instead of a plain string with the latest revisions
to the HCP Packer SBOM support feature, we update how we reference those
values for the SBOM format to use that enum instead.
When a build cannot be completed without errors, the build state was
left as running, unless the build explicitly failed, which meant that
HCP Packer would be responsible for changing the status after the
heartbeats for the build stopped being sent for two 5m periods.
This commit changes this behaviour, by explicitly marking the build as
failed if something did not work while trying to complete a build on HCP
Packer, even if the local Packer core build succeeded before that.
Since packer now supports keeping track of SBOMs produced during a
build, we add the code to integrate those changes into the internal/hcp
package, so we do upload them on build completion.
Since the DAG package was lifted from Terraform, its contents are more
than what we need for now, so this commit cleans-up the package to keep
only the currently needed parts of code.
If we need to support more in the future, we can revert this commit, or
pickup the changes again from Terraform.
The implementation of the DAG as extracted from Terraform relied on a
Root vertex being injected into the graph as the last node to visit.
This is used as a sanity check for Terraform, but doesn't apply to our
use-case for now, as we are always executing everything and have no need
for this root node.
Instead, we change how Validate operates so it does not error in case
there is no valid root node for the graph, but enables us calling it to
check for self-referencing edges, and circular dependencies.
