Description

  • Refactored agent architecture to support push-based gateway communication instead of pull-based approach

  • Added GatewayClient for agent-to-gateway gRPC communication with reconnection and backoff logic

  • Implemented PushLoop for periodic agent status pushing with enrollment, config polling, and state management

  • Extended protobuf definitions with new gateway communication messages (GatewayStatusRequest, GatewayStatusResponse, GatewayStatusChunk) and agent configuration messages (AgentHelloRequest, AgentHelloResponse, AgentConfigRequest, AgentConfigResponse)

  • Added new AgentGatewayService gRPC service with Hello, GetConfig, PushStatus, and StreamStatus methods

  • Implemented NATS account management service with JWT/NKey cryptographic operations for operator bootstrap, tenant account creation, and user credential generation

  • Added NATSAccountService gRPC service with six RPC methods for NATS JWT signing operations

  • Implemented NATS operator management with key generation and JWT signing capabilities

  • Added comprehensive test suites for NATS account service (474 lines) and user credential generation (440 lines)

  • Updated agent Server struct to remove listener-based architecture and add gateway configuration fields (GatewayAddr, GatewaySecurity, PushInterval, TenantID, TenantSlug)

  • Added NATS credentials file support in event writer service

  • Added CLI handlers for NATS bootstrap operations and account management

  • Added Elixir production configuration files for both core and agent-gateway applications

PR Compliance Guide 🔍

Below is a summary of compliance checks for this PR:

Security Compliance
Sensitive secret exposure

Description: The newly added gRPC/protobuf API includes highly sensitive secrets in plaintext fields
(e.g., CreateTenantAccountResponse.account_seed,
BootstrapOperatorResponse.operator_seed/system_account_seed,
GenerateUserCredentialsResponse.creds_file_content, and request fields like
GenerateUserCredentialsRequest.account_seed), which can lead to credential/tenant
compromise if these RPCs are reachable without strict mTLS + strong
authentication/authorization and if responses/requests are logged or intercepted.
nats_account.pb.go [238-874]

Referred Code
// CreateTenantAccountRequest is the request to create a new tenant NATS account.

	state           protoimpl.MessageState `protogen:"open.v1"`
	TenantSlug      string                 `protobuf:"bytes,1,opt,name=tenant_slug,json=tenantSlug,proto3" json:"tenant_slug,omitempty"`                // Unique tenant identifier (e.g., "acme-corp")
	Limits          *AccountLimits         `protobuf:"bytes,2,opt,name=limits,proto3" json:"limits,omitempty"`                                          // Optional resource limits

Codebase Duplication Compliance
Codebase context is not defined

Follow the guide to enable codebase context checks.

Custom Compliance
🟢
Generic: Meaningful Naming and Self-Documenting Code

Objective: Ensure all identifiers clearly express their purpose and intent, making code
self-documenting

Status: Passed

Learn more about managing compliance generic rules or creating your own custom rules

Generic: Comprehensive Audit Trails

Objective: To create a detailed and reliable record of critical system actions for security analysis
and compliance.

Status:
Audit logging unclear: The diff provided does not include the new NATS account service and gateway push handlers,
so it cannot be verified that critical actions (operator bootstrap, tenant account
creation, credential generation, JWT push) are consistently audit-logged with actor
identity, timestamp, action, and outcome.

Referred Code
/*

Learn more about managing compliance generic rules or creating your own custom rules

Generic: Robust Error Handling and Edge Case Management

Objective: Ensure comprehensive error handling that provides meaningful context and graceful
degradation

Status:
Error handling unverified: The diff provided does not include the new GatewayClient, PushLoop, and NATSAccountService
implementations, so it cannot be verified that external-call failure paths (gRPC,
crypto/JWT ops, file I/O, reconnection/backoff) have complete contextual errors and
edge-case handling.

Referred Code
/*

Learn more about managing compliance generic rules or creating your own custom rules

Generic: Secure Error Handling

Objective: To prevent the leakage of sensitive system information through error messages while
providing sufficient detail for internal debugging.

Status:
Sensitive errors unverified: The service code returning errors for operations involving seeds/JWTs is not shown, so it
cannot be verified that user-facing errors do not expose sensitive details (e.g.,
revealing account existence or returning crypto parsing failures verbatim).

Referred Code
/*

Generic: Secure Logging Practices

Objective: To ensure logs are useful for debugging and auditing without exposing sensitive
information like PII, PHI, or cardholder data.

Status:
Secret fields introduced: New protobuf messages include highly sensitive fields (e.g., account_seed,
existing_operator_seed, creds_file_content), and without the corresponding handler/logging
code it cannot be verified these values are never logged or emitted in structured logs.

Referred Code
// CreateTenantAccountResponse returns the generated account credentials.
// The account_seed should be stored encrypted by the caller (Elixir/AshCloak).
type CreateTenantAccountResponse struct {
	state            protoimpl.MessageState `protogen:"open.v1"`

Generic: Security-First Input Validation and Data Handling

Objective: Ensure all data inputs are validated, sanitized, and handled securely to prevent
vulnerabilities

Status:
Input validation unverified: The PR introduces new external inputs via gRPC (tenant slug, seeds/JWTs, permissions,
mappings) but the diff does not include the server-side validation/authn/authz logic, so
secure validation and authorization of these sensitive operations cannot be confirmed.

Referred Code

Re-evaluate building a custom NATS account service

The PR builds a custom NATS account and JWT management service. It is suggested
to re-evaluate this approach and consider using the official nats-account-server
to reduce complexity and security risks.

Examples:

pkg/datasvc/nats_account_service.go [42-888]
proto/nats_account.pb.go [1-1266]

Solution Walkthrough:

Before:

// pkg/datasvc/nats_account_service.go
// Custom gRPC service for NATS account management
class NATSAccountServer implements proto.NATSAccountServiceServer {
    operator: accounts.Operator
    signer: accounts.AccountSigner

    func BootstrapOperator(req) {
        // Use custom 'accounts' package to create operator keys/JWTs
        operator, result, err := accounts.BootstrapOperator(...)
        this.operator = operator
        this.signer = accounts.NewAccountSigner(operator)
        return result
    }

    func CreateTenantAccount(req) {
        // Use custom 'signer' to create tenant keys/JWTs
        result, err := this.signer.CreateTenantAccount(...)
        return result
    }
    // ... other methods for signing, generating creds, etc.
}

After:

// Interacting with the official nats-account-server
// The custom gRPC service might be removed or simplified.
class NatsProvisioner {
    nats_account_server_url: "http://nats-account-server:8080"

    func create_tenant_account(tenant_slug) {
        // Make an HTTP request to the official nats-account-server API
        // to create or update an account.
        // The logic for JWT signing is handled by the external server.
        http.post(
            `${this.nats_account_server_url}/accounts/${tenant_slug}`,
            { name: tenant_slug, ... }
        )
    }

    func generate_user_creds(tenant_slug, user_name) {
        // Request user credentials from the nats-account-server
        response = http.post(
            `${this.nats_account_server_url}/accounts/${tenant_slug}/users/${user_name}`,
            { ... }
        )
        return response.creds_file
    }
}

Suggestion importance[1-10]: 9

__

Why: The suggestion raises a critical architectural concern about implementing a custom, security-sensitive NATS account management service instead of using the official nats-account-server, which could significantly impact the project's security and maintainability.

High
Security
Restrict overly permissive user permissions

Restrict the overly broad permissions for the platform user in
generatePlatformAccount from > to a specific list of subjects to enhance
security.

pkg/cli/nats_bootstrap.go [603-608]

 	permissions := &accounts.UserPermissions{
-		PublishAllow:   []string{">"},
-		SubscribeAllow: []string{">"},
+		PublishAllow: []string{
+			"events.>",
+			"snmp.traps",
+			"logs.>",
+			"telemetry.>",
+			"netflow.>",
+		},
+		SubscribeAllow: []string{
+			"events.>",
+			"snmp.traps",
+			"logs.>",
+			"telemetry.>",
+			"netflow.>",
+		},
 		AllowResponses: true,
 		MaxResponses:   1000,
 	}

[To ensure code accuracy, apply this suggestion manually]

Suggestion importance[1-10]: 9

__

Why: This is a critical security suggestion that correctly identifies overly permissive permissions (>) and proposes restricting them to only the necessary subjects, adhering to the principle of least privilege.

High
Possible issue

network payloads and improve data consistency. This change should be applied to
the source .proto file.

Why: The suggestion correctly identifies redundant fields in the GatewayServiceStatus message, which can impact network payload size and data consistency, and rightly points out the change needs to be in the .proto file.

Medium
Fix incorrect URL parsing logic

Fix a bug in applyPortToPathLike where targets with a host and path (e.g.,
example.com/path) are parsed incorrectly. The fix involves splitting the host
and path before parsing to ensure the URL is constructed correctly.

pkg/agent/push_loop.go [796-813]

 func applyPortToPathLike(target string, port int32, checkerType string, wantHTTPS bool) string {
 	// Path-like target (e.g., "example.com/path"): for HTTP checks, normalize into a URL and apply port.
 	if checkerType != httpCheckType {
 		return target
 	}
 	scheme := "http://"
 	if wantHTTPS {
 		scheme = "https://"
 	}
-	parsedURL, err := url.Parse(scheme + target)
+
+	hostPart := target
+	pathPart := ""
+	if i := strings.Index(target, "/"); i != -1 {
+		hostPart = target[:i]
+		pathPart = target[i:]
+	}
+
+	parsedURL, err := url.Parse(scheme + hostPart)
 	if err != nil || parsedURL.Host == "" {
-		return target
+		return target // Could not parse host part, return original
 	}
+
 	if parsedURL.Port() == "" {
 		parsedURL.Host = net.JoinHostPort(parsedURL.Hostname(), fmt.Sprintf("%d", port))
 	}
+	parsedURL.Path = pathPart
+
 	return parsedURL.String()
 }

[To ensure code accuracy, apply this suggestion manually]

Suggestion importance[1-10]: 7

__

Why: The suggestion correctly identifies a bug in URL parsing for targets containing both a host and a path, and provides a valid fix. This improves the robustness of the check configuration logic.

Medium
Improve verification by ignoring commented lines

Improve the NATS configuration verification by parsing the file line-by-line,
ignoring empty or commented lines to prevent false positives from
strings.Contains.

pkg/cli/nats_bootstrap.go [647-668]

 	configStr := string(content)
 	checks := []struct {
 		name    string
 		pattern string
 	}{
 		{"operator", "operator:"},
 		{"system_account", "system_account:"},
 		{"resolver", "resolver:"},
 	}
 
 	fmt.Printf("Verifying NATS configuration: %s\n", configPath)
 	fmt.Println()
 
+	// Create a map of found directives for efficient lookup
+	foundDirectives := make(map[string]bool)
+	scanner := bufio.NewScanner(strings.NewReader(configStr))
+	for scanner.Scan() {
+		line := strings.TrimSpace(scanner.Text())
+		if line == "" || strings.HasPrefix(line, "#") || strings.HasPrefix(line, "//") {
+			continue
+		}
+		for _, check := range checks {
+			if strings.HasPrefix(line, check.pattern) {
+				foundDirectives[check.name] = true
+			}
+		}
+	}
+
 	allPassed := true
 	for _, check := range checks {
-		if strings.Contains(configStr, check.pattern) {
+		if foundDirectives[check.name] {
 			fmt.Printf("[OK] %s configuration found\n", check.name)
 		} else {
 			fmt.Printf("[FAIL] %s configuration missing\n", check.name)
 			allPassed = false
 		}
 	}

[To ensure code accuracy, apply this suggestion manually]

Suggestion importance[1-10]: 6

__

Why: The suggestion correctly identifies a bug where strings.Contains would falsely validate commented-out configuration lines, and the proposed fix of parsing line-by-line while ignoring comments is a robust improvement to the verification logic.

Low
Enable graceful flag error handling

Replace flag.ExitOnError with flag.ContinueOnError in flag sets to enable
graceful error handling for malformed flags instead of exiting the program.

pkg/cli/nats_bootstrap.go [53]

-fs := flag.NewFlagSet("nats-bootstrap", flag.ExitOnError)
+fs := flag.NewFlagSet("nats-bootstrap", flag.ContinueOnError)

[To ensure code accuracy, apply this suggestion manually]

Suggestion importance[1-10]: 5

__

Why: The suggestion correctly points out that using flag.ContinueOnError allows for more graceful error handling in a CLI application, which improves robustness and testability.

Low
General
Improve file existence checking

Enhance the file existence check by handling all errors from os.Stat and
verifying that the provided path is a regular file, not a directory.

pkg/cli/nats_bootstrap.go [636-638]

-if _, err := os.Stat(configPath); os.IsNotExist(err) {
-    return fmt.Errorf("%w: %s", errNATSConfigNotFound, configPath)
+info, err := os.Stat(configPath)
+if err != nil {
+    if os.IsNotExist(err) {
+        return fmt.Errorf("%w: %s", errNATSConfigNotFound, configPath)
+    }
+    return fmt.Errorf("cannot stat config file %s: %w", configPath, err)
+}
+if !info.Mode().IsRegular() {
+    return fmt.Errorf("config path %s is not a file", configPath)
 }

[To ensure code accuracy, apply this suggestion manually]

Suggestion importance[1-10]: 6

__

Why: This suggestion improves the robustness of the file verification by adding checks for non-existence errors and ensuring the path points to a regular file, not a directory, preventing potential runtime issues.

Low
remove stale checker configs

Uncomment the logic in applyChecks to remove stale checker configurations from
p.server.checkerConfs. This prevents configurations from accumulating
indefinitely after they are removed from the gateway.

pkg/agent/push_loop.go [657-664]

-// Optionally: remove checks that are no longer in the config
-// (commented out for now - may want to keep local file-based checks)
-// for name := range p.server.checkerConfs {
-// 	if !seenChecks[name] {
-// 		delete(p.server.checkerConfs, name)
-// 		p.logger.Info().Str("name", name).Msg("Removed stale check")
-// 	}
-// }
+for name := range p.server.checkerConfs {
+	if !seenChecks[name] {
+		delete(p.server.checkerConfs, name)
+		p.logger.Info().Str("name", name).Msg("Removed stale check")
+	}
+}

[To ensure code accuracy, apply this suggestion manually]

Suggestion importance[1-10]: 5

__

Why: The suggestion correctly points out that commented-out code would prevent the cleanup of stale checker configurations, potentially leading to a memory leak. Uncommenting it improves the agent's long-term stability.
