Version 4.4.1

  • The PLUTO_MARK_IN and PLUTO_ESP_ENC environment variables can be used
    in a user-specific updown script to set marks on inbound ESP or
    ESP_IN_UDP packets.
  • The openssl plugin now supports X.509 certificate and CRL functions. The use of the Online
    Certificate Status Protocol (OCSP) still requires the x509 plugin, though.
    X.509 attribute certificate handling rely on the x509 plugin as well.
  • OCSP/CRL checking in IKEv2 has been moved to the revocation plugin, enabled
    by default. Plase update manual load directives in strongswan.conf.
  • RFC3779 ipAddrBlock constraint checking has been moved to the addrblock
    plugin, disabled by default. Enable it and update manual load directives
    in strongswan.conf, if required.
  • Issue a warning if explicit load lists are used. Since the number of pluto
    and charon plugins are increasing steadily with each release and explicit load
    lists might become obsoleted, a warning is now issued by ipsec starter if explicit
    load lists are found in strongswan.conf since we don't recommend their use for
    inexperienced users. Experts read on here.
  • The pki utility supports CRL generation using the --signcrl command.
  • The ipsec pki --self, --issue and --req commands now support output in
    PEM format using the --outform pem option.
  • The major refactoring of the IKEv1 Mode Config functionality now allows
    the transport and handling of arbitrary Mode Config attributes.
  • The RADIUS proxy plugin eap-radius now supports multiple servers. Configured
    servers are chosen randomly, with the option to prefer a specific server.
    Non-responding servers are degraded by the selection process.
  • The ipsec pool tool manages arbitrary configuration attributes stored
    in an SQL database. ipsec pool --help gives the details.
  • The new eap-simaka-sql plugin acts as a backend for EAP-SIM and EAP-AKA,
    reading triplets/quintuplets from an SQL database.
  • The High Availability plugin now supports a HA enabled in-memory address
    pool and Node reintegration without IKE_SA rekeying. The latter allows
    clients without IKE_SA rekeying support to keep connected during
    reintegration. Additionally, many other issues have been fixed in the ha
  • Fixed a potential remote code execution vulnerability resulting from
    the misuse of snprintf(). The vulnerability was introduced with the
    strongswan-4.3.3 release and is exploitable by unauthenticated users.
    Patches for all releases starting with 4.3.3 are available.
