Aspen Mesh Platform features#

  • ASM-5458: The Packet Inspector 1 Aggregator now supports multi-destination packet forwarding, enabling the aggregator to send identical packet captures to up to five analysis destinations simultaneously (one primary and up to four secondaries).

    To enable multi-destination mode, add secondary destination addresses to the addressesSecondary list in the Packet Inspector 1 aggregator override values file and run helm upgrade. The aggregator automatically reuses the primary TLS certificates for secondaries in the same Istio trust domain. For secondaries using a different Certificate Authority (CA), provide per-destination certificate paths using certPathsSecondary, clientCertPathsSecondary, and clientKeyPathsSecondary.

    A new Prometheus metric, aspenmesh_packet_inspector_requests_to_secondary_analysis_total, tracks secondary delivery success and failure counts.

    Important

    This feature is backward-compatible. Existing single-destination deployments work without any configuration changes when addressesSecondary is empty or omitted. Multi-destination applies to Packet Inspector 1 only. Packet Inspector 2 is not supported.

  • ASM-5508: Added istioctl-lite, a new reduced-functionality CLI binary included in the Aspen Mesh release tarball alongside istioctl. Use istioctl-lite to diagnose and troubleshoot the service mesh without the ability to install, modify, or remove it. This binary is intended for environments where you need to separate operational duties from administrative duties.

    The following table shows which commands are available in istioctl-lite:

    Command

    In-place mesh upgrades

    If you run a removed command, istioctl-lite returns an “unknown command” error and exits with a non-zero status code. No part of the removed command’s action is performed.

    Important

    istioctl-lite is available only in Aspen Mesh 1.21.6-am5 and later. The command set is fixed at build time and cannot be changed through configuration.

    To extract and verify the binary:

    tar -xzf aspenmesh-carrier-grade-<version>.tar.gz
    ls */bin/istioctl-lite
    ./istioctl-lite version --remote=false -o json
    
  • ASM-5325: Protect your services from identity spoofing by upgrading to Aspen Mesh 1.21.6-am5, which enforces SANITIZE_SET as the default X-Forwarded-Client-Cert (XFCC) header handling mode for ingress/egress gateways and sidecar inbound listeners. With this change, the proxy automatically discards any client-supplied XFCC header and replaces it with a verified entry based on the authenticated TLS certificate, ensuring your services always receive trusted client identity information without additional configuration.

    To customize the XFCC handling mode, update the following values in your Aspen Mesh override values file:

    meshConfig:
      defaultConfig:
        # Applies to ingress/egress gateway HCM
        gatewayTopology:
          forwardClientCertDetails: <VALUE>
        # Applies to sidecar inbound HCM
        proxyHeaders:
          forwardedClientCert: <VALUE>
    

    VALUE

    Description

    UNDEFINED

    Field is not set.

    SANITIZE

    Do not send the XFCC header to the next hop.

    FORWARD_ONLY

    When the client connection is mTLS (Mutual TLS), forward the XFCC header in the request.

    APPEND_FORWARD

    When the client connection is mTLS, append the client certificate information to the request’s XFCC header and forward it.

    SANITIZE_SET

    When the client connection is mTLS, reset the XFCC header with the client certificate information and send it to the next hop. This is the default value for a gateway.

    ALWAYS_FORWARD_ONLY

    Always forward the XFCC header in the request, regardless of whether the client connection is mTLS.

    After updating the override file, apply the changes by upgrading istiod:

    helm upgrade istiod manifests/charts/istio-control/istio-discovery \
      --namespace istio-system \
      --values aspen-mesh-override-values.yaml
