From 243c5bf9997bbb8605822bb6b46740fa54068e06 Mon Sep 17 00:00:00 2001 From: Anderson Toshiyuki Sasaki Date: Tue, 17 Feb 2026 14:15:59 +0100 Subject: [PATCH 01/61] crypto: Make pkey_pub_from_pem and rsa_oaep_encrypt public These functions were previously only available in the crypto::testing module. Move them to the main crypto module as proper public API, with CryptoError variants for structured error handling. The testing module versions now delegate to the production implementations, preserving backward compatibility. The goal is to make them available to other crates.

Restore strict lint denies now that all code paths are connected.

Measured boot policies are JSON documents that specify: +//! - Expected PCR values for different boot stages +//! - Allowed boot components and their hashes +//! - Acceptable kernel configurations +//! - Trusted modules and drivers +//! +//! # Command Types +//! +//! - [`MeasuredBootAction::Push`]: Push a measured boot policy to the verifier +//! - [`MeasuredBootAction::Show`]: Display an existing policy +//! - [`MeasuredBootAction::Update`]: Update an existing policy +//! - [`MeasuredBootAction::Delete`]: Remove a policy +//! - [`MeasuredBootAction::List`]: List all available policies +//! +//! # Security Considerations +//! +//! - Policies must be validated before deployment +//! - Changes to policies affect agent attestation immediately +//! - Invalid policies can prevent agent enrollment +//! - Policy management requires proper authorization +//! +//! # Examples +//! +//! ```rust +//! use keylimectl::commands::measured_boot; +//! use keylimectl::config::Config; +//! use keylimectl::output::OutputHandler; +//! use keylimectl::MeasuredBootAction; +//! +//! # async fn example() -> Result<(), Box> { +//! let config = Config::default(); +//! let output = OutputHandler::new(crate::OutputFormat::Json, false); +//! +//! // Push a measured boot policy to the verifier +//! let push_action = MeasuredBootAction::Push { +//! name: "secure-boot-policy".to_string(), +//! file: "/etc/keylime/policies/secure-boot.json".to_string(), +//! }; +//! +//! let result = measured_boot::execute(&push_action, &config, &output).await?; +//! println!("Policy pushed: {:?}", result); +//! +//! // List all policies +//! let list_action = MeasuredBootAction::List; +//! let policies = measured_boot::execute(&list_action, &config, &output).await?; +//! # Ok(()) +//! # } +//! ``` + +use crate::client::factory; +use crate::commands::error::CommandError; +use crate::error::KeylimectlError; +use crate::output::OutputHandler; +use crate::MeasuredBootAction; +use chrono; +use log::debug; +use serde_json::{json, Value}; +use std::fs; + +/// Execute a measured boot policy management command +/// +/// This is the main entry point for all measured boot policy operations.

Registrar public methods (get_agent, delete_agent, list_agents) remain version-agnostic since they use self.api_version in URL construction with the same endpoint pattern.

Key changes: - --timeout global flag overrides client.timeout - Running without subcommand shows config summary + clap help - `configure` subcommand with interactive wizard (wizard feature flag) and --non-interactive mode for scripted configuration - Config struct tracks loaded_from path, has_config_file() helper - .keylimectl/config.toml added as highest-priority auto-discovery path - 348 tests

Info commands work even with incomplete configuration (warn on validation instead of exiting), making them useful for troubleshooting. Subcommands: - `info` (no subcommand): local diagnostics with version, features, config file search results, effective config with per-field source annotations (cli/env_var/config_file/default), KEYLIME_* env vars - `info verifier`: connect to verifier, report API version, agent count - `info registrar`: connect to registrar, report API version, agent count - `info agent `: combined verifier+registrar view with summary - `info tls`: validate cert files, check expiration, verify cert/key pair Infrastructure: - CliOverrides struct tracks which CLI args were provided for source annotation in the info command - Config::config_search_paths() exposes file search paths - RegistrarClient::api_version() public getter added - Info command gets its own match arm in main() with validation bypass Note: potential sensitive env vars with the following suffixes are redacted in info output: - *_PASSWORD - *_SECRET - *_KEY_DATA - *_TOKEN Co-Authored-By: Claude Opus 4.6 Signed-off-by: Anderson Toshiyuki Sasaki --- keylimectl/src/client/agent.rs | 1 + keylimectl/src/client/base.rs | 1 + keylimectl/src/client/registrar.rs | 7 + keylimectl/src/client/verifier.rs | 1 + keylimectl/src/commands/agent/mod.rs | 4 +- keylimectl/src/commands/configure.rs | 4 +- keylimectl/src/commands/info/agent_info.rs | 339 ++++++++++++ keylimectl/src/commands/info/mod.rs | 40 ++ .../src/commands/info/registrar_info.rs | 111 ++++ keylimectl/src/commands/info/self_info.rs | 356 +++++++++++++ keylimectl/src/commands/info/tls_info.rs | 485 ++++++++++++++++++ keylimectl/src/commands/info/verifier_info.rs | 135 +++++ keylimectl/src/commands/measured_boot.rs | 4 +- keylimectl/src/commands/mod.rs | 1 + keylimectl/src/commands/policy.rs | 4 +- keylimectl/src/config/singleton.rs | 1 + keylimectl/src/config_main.rs | 34 ++ keylimectl/src/main.rs | 55 ++ keylimectl/tests/info.rs | 259 ++++++++++ 19 files changed, 1838 insertions(+), 4 deletions(-) create mode 100644 keylimectl/src/commands/info/agent_info.rs create mode 100644 keylimectl/src/commands/info/mod.rs create mode 100644 keylimectl/src/commands/info/registrar_info.rs create mode 100644 keylimectl/src/commands/info/self_info.rs create mode 100644 keylimectl/src/commands/info/tls_info.rs create mode 100644 keylimectl/src/commands/info/verifier_info.rs create mode 100644 keylimectl/tests/info.rs diff --git a/keylimectl/src/client/agent.rs b/keylimectl/src/client/agent.rs index 397fab9f4..3846a1ed6 100644 --- a/keylimectl/src/client/agent.rs +++ b/keylimectl/src/client/agent.rs @@ -761,6 +761,7 @@ mod tests { fn create_test_config() -> Config { Config { loaded_from: None, + cli_overrides: crate::config::CliOverrides::default(), verifier: crate::config::VerifierConfig::default(), registrar: crate::config::RegistrarConfig::default(), tls: TlsConfig { diff --git a/keylimectl/src/client/base.rs b/keylimectl/src/client/base.rs index fc3549722..ef69cb9dd 100644 --- a/keylimectl/src/client/base.rs +++ b/keylimectl/src/client/base.rs @@ -366,6 +366,7 @@ mod tests { fn create_test_config() -> Config { Config { loaded_from: None, + cli_overrides: crate::config::CliOverrides::default(), verifier: VerifierConfig { ip: "127.0.0.1".to_string(), port: 8881, diff --git a/keylimectl/src/client/registrar.rs b/keylimectl/src/client/registrar.rs index 515b3a2b8..0b15e77e3 100644 --- a/keylimectl/src/client/registrar.rs +++ b/keylimectl/src/client/registrar.rs @@ -777,6 +777,12 @@ impl RegistrarClient { /// # Ok(()) /// # } /// ``` + /// Get the detected API version + pub fn api_version(&self) -> &str { + &self.api_version + } + + /// List all agents registered with the registrar pub async fn list_agents(&self) -> Result { debug!("Listing agents on registrar");

Add new CLI subcommands for local policy tools: - policy generate runtime/measured-boot/tpm - policy sign (DSSE signing) - policy verify-signature - policy validate - policy convert (legacy format conversion) - verify evidence (top-level command for one-shot attestation) Add new error types: PolicyGenerationError, DsseError, EvidenceError. Create policy_tools module skeleton for shared policy logic.

Create uefi_event_data module for parsing UEFI_VARIABLE_DATA and EV_IPL event data structures. Extract boot chain entries (shim/grub/kernel from PCR 4), kernel command line (PCR 8), initrd/vmlinuz digests (PCR 9), MOK digests (MokList/MokListX), and vendor_db from EV_EFI_VARIABLE_AUTHORITY events. Add vmlinuz_plain_sha256 field to KernelEntry for non-SecureBoot systems.

Implement generate_from_tpm() that opens the local TPM via TCTI, reads PCR values for requested indices and hash algorithm, and builds a TpmPolicy. On permission errors accessing /dev/tpmrm0, suggest running with sudo. Pass hash_alg through from CLI to TPM generation. Without the feature flag, --from-tpm produces a clear error naming the required feature.

Supports gzip, zstd, xz, and bzip2 compression formats with CPIO new-ASCII archive parsing. Key components: - Compression detection via magic bytes with automatic decompression - Early microcode CPIO archive detection and skipping - In-memory CPIO parsing that hashes files without extracting to disk - Privilege detection for /boot directory access with sudo suggestion Co-Authored-By: Claude Opus 4.6 Signed-off-by: Anderson Toshiyuki Sasaki --- Cargo.lock | 88 ++- keylimectl/Cargo.toml | 4

Local repos are scanned for RPM files and their headers are parsed for file digests. Remote repos use filelists-ext.xml as a fast path, falling back to downloading individual RPMs. Key components: - RPM header parsing via pure-Rust rpm crate (no librpm-devel needed) - repomd.xml and filelists-ext.xml parsing via quick-xml - Automatic decompression of metadata files (gzip, xz, zstd, bzip2) - Feature-gated: rebuild with --features rpm-repo to enable Co-Authored-By: Claude Opus 4.6

Instead, use the attestation_status field ("PENDING", "PASS", "FAIL") which the verifier computes for both push and pull mode agents. On failure, report the operational state, severity level, and last event ID so the user understands why attestation failed. On timeout, use the correct error type to avoid the misleading "Failed to list verifier" message.

Spinners auto-detect TTY on stderr and fall back to plain text when piped. Colors apply to stderr only, keeping stdout clean for machine consumption. New --color flag (auto|always|never) controls color output. The OutputHandler now supports start_wait() which returns an RAII WaitHandle for polling loops with live status updates.

charset=UTF-8 Content-Transfer-Encoding: 8bit Add --interactive (-I) flag to 'policy generate runtime' that launches a step-by-step wizard using dialoguer prompts. The wizard guides users through selecting input sources, configuring paths, setting IMA options, choosing a hash algorithm, and specifying output — then delegates to the existing generate_runtime() function. The wizard is gated behind the 'wizard' feature flag, matching the existing pattern used by the configure command.

The wizard prompts for the UEFI event log path, whether to include Secure Boot variables, shows a preview of event log statistics (total events, S-CRTM entries, algorithms), asks for the output file, and confirms before generating. Uses the existing get_eventlog_stats() function for the preview step, replacing #[allow(dead_code)] with a conditional cfg_attr gate.

The wizard prompts for evidence type (TPM/TEE), required files (nonce, quote, AK, EK), hash algorithm, policy files (at least one required), measurement logs (conditional on selected policies), and confirms with a summary before sending to the verifier. The nonce, quote, tpm-ak, and tpm-ek fields are now optional in the CLI definition (using required_unless_present = "interactive") so the wizard can prompt for them instead. Non-interactive mode validates their presence explicitly.

These directories contain volatile or virtual data with no meaningful integrity to verify. The default excluded paths are automatically merged with user-provided --skip-path values. When a user path is already covered by a default (e.g. --skip-path /var/log is under /var), a note is printed to inform the user it has no additional effect. Default paths are resolved relative to --rootfs so scanning /mnt/image correctly skips /mnt/image/sys, etc. Refactor filesystem scanning to use Rayon for parallel digest calculation: file discovery remains sequential (I/O-bound directory walk), but hash computation runs across all available CPU cores. Directory permission errors are now non-fatal (logged and skipped).

charset=UTF-8 Content-Transfer-Encoding: 8bit Match the Python tenant's process_policy() behavior by automatically enabling PCR bits in the TPM policy mask when attestation policies are attached: - runtime policy → enables IMA PCR 10 - measured boot policy → enables measured boot PCRs (0-9, 11-15) Without this, keylimectl sent {"mask":"0x0"} regardless of attached policies, causing the verifier to skip TPM challenge generation and reject attestations with "challenges expired at None" (403). Also add a hard error when no attestation policy (--runtime-policy, --mb-policy, --tpm-policy, or --runtime-policy-name) is provided, since the verifier cannot attest an agent without at least one policy.

This produced misleading error messages like "Failed to write output to /sys/kernel/.../binary_bios_measurements" for what is actually a read/parse error. Add a dedicated EventLogParse variant and use it in generate_from_eventlog() and get_eventlog_stats(), producing clear messages like "Failed to parse event log /sys/.../binary_bios_measurements: IO error: No such file".

When repomd.xml.asc is present the signature is verified against the public key supplied via --gpg-key or, if absent, the bundled repomd.xml.key file. If the signature file is absent a warning is emitted and processing continues; if verification fails the command aborts with an error. The implementation uses sequoia-openpgp (crypto-openssl backend) so no GPG binary or temporary keyring is required. A new gpg_verify module provides the core verify_detached_signature() function with unit tests covering valid, tampered, wrong-key, and bad-data scenarios.

Previously these args were always visible and produced runtime errors when used without the feature. Now they are omitted from the binary entirely: - --interactive / -I: gated behind "wizard" feature - --local-rpm-repo, --remote-rpm-repo, --gpg-key: gated behind "rpm-repo" - --from-tpm: gated behind "tpm-local" or "tpm-quote-validation" Update destructuring patterns in generate.rs and evidence.rs to match, passing None/false defaults when features are disabled. Gate the corresponding integration tests behind the same feature flags.

If the verifier responds to DELETE with 202 Accepted (meaning deletion is still in progress because an in-flight attestation cycle has not completed), sending POST immediately causes a 409 Conflict. Fix by moving the polling logic into remove_agent(): after DELETE, if the response is 202, poll the verifier with exponential backoff until the agent returns 404 before returning to the caller. This gives remove_agent() a clean post-condition — when it returns successfully, the agent is fully gone — regardless of whether the caller is agent remove or agent update. The polling uses the retry configuration from keylimectl.conf (retry_interval, exponential_backoff, max_retries) and shows a spinner with progress information. This mirrors the behavior of the upstream Python tenant (do_cvdelete / do_cvadd), hardened against this race condition by upstream PRs keylime/keylime#1874 and keylime/keylime#1902. Also fix the misleading error message in add_agent() that suggested "keylimectl agent add" when enrollment fails with a conflict; it now directs the user to "keylimectl agent update" or remove-then-add.

Add an [agent] config section with broad defaults that accept all strong algorithm variants, excluding weak ones (sha1, rsa1024, ecc192, ecc224). Values can be restricted via config file or KEYLIME_AGENT__ACCEPT_TPM_* environment variables.

This broke shell scripting and CI pipelines that rely on exit codes. Add a `ValidationFailed` error variant to `KeylimectlError` that carries structured validation details. Commands now return `Err` when validation/verification fails, producing exit code 10 with the validation details preserved in the JSON error output.

ECDSA keys in SEC1 format (BEGIN EC PRIVATE KEY) and traditional RSA keys (BEGIN RSA PRIVATE KEY) caused a "builder error" when configuring mTLS. Use OpenSSL's PKey::private_key_from_pem to parse any PEM key format, then re-encode as PKCS#8 before passing to reqwest. This fixes the TLS configuration error with ECDSA certificates.
