Issue

Under certain conditions, modifying the TLS cipher suites via the REST API can result in the mgwd process crashing on any or all nodes in the cluster. Specifically:

  • FIPS mode (-is-fips-enabled in CLI, /api/security/fips.enabled in REST) is true
  • The mgwd process has been restarted (directly or indirectly) since FIPS mode was turned on
  • The target configuration specified via REST contains at least one suite that is not supported in FIPS mode
    • TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256 is one specific example
    • In general any CHACHA20_POLY1205 is not supported in FIPS mode
