From bcbb22e4fe0ea7ee13aafc766209e335d5c5b7df Mon Sep 17 00:00:00 2001 From: arewm Date: Tue, 20 Jan 2026 12:10:52 -0500 Subject: [PATCH 1/4] feat: add --vsa-format flag to support multiple VSA output formats Add support for generating VSAs in different formats to enable flexible signing workflows. The new --vsa-format flag accepts two values: - "dsse" (default): Generates complete DSSE envelope with signature (existing behavior, requires --vsa-signing-key) - "predicate": Generates raw VSA predicate JSON without signature (new capability, enables downstream signing with correct subject) This addresses the challenge in release pipelines where images are validated before being pushed to destination registries. With predicate format, validation can generate unsigned VSAs that are later signed with the correct image location after the push completes. The implementation maintains backward compatibility by defaulting to "dsse" format and reuses existing VSA generation functions. Format validation ensures only supported values are accepted. Updated verify-conforma-konflux-ta task to support VSA generation with parameters for format selection, signing key configuration, and trusted artifact storage integration.

Changes: - Modify extractLocalPath() to return error instead of defaulting to /tmp/vsa when no local@ path is found, preventing silent data loss - Update acceptance test snapshot to include VSA_GENERATED result field added by the VSA format feature - Update auto-generated documentation for verify-conforma-konflux-ta task The security concern about arbitrary file writes is a false positive - the CLI runs with user permissions and the user explicitly controls the destination path, similar to mkdir or cp commands.

Changes: - Rename --vsa-format to --attestation-format - Rename --vsa-output-dir to --attestation-output-dir - Move format/signing-key validation from RunE to PreRunE per review feedback - Add comprehensive test coverage for path validation and error handling - Fix Writer to handle both temp directory prefixes and absolute paths - Add path traversal protection (restrict output to /tmp or workspace) These flags were introduced in this PR and have not been released, making this rename non-breaking. Existing VSA flags (--vsa, --vsa-signing-key, --vsa-upload, --vsa-expiration) remain unchanged. Security: Validates output paths to prevent writing to arbitrary filesystem locations. While this is a CLI tool running with user permissions, the validation provides defense-in-depth for CI/CD environments. Addresses PR feedback from Joe Stuart on PreRunE validation pattern.
