Version 5.0.2

  • Implemented all IETF Standard PA-TNC attributes and an OS IMC/IMV
    pair using them to transfer operating system information.
  • The new ipsec listcounters command prints a list of global counter values
    about received and sent IKE messages and rekeyings.
  • A new lookip plugin can perform fast lookup of tunnel information using a
    clients virtual IP and can send notifications about established or deleted
    tunnels. The "ipsec lookip" command can be used to query such information
    or receive notifications.
  • The new error-notify plugin catches some common error conditions and allows
    an external application to receive notifications for them over a UNIX socket.
  • IKE proposals can now use a PRF algorithm different to that defined for
    integrity protection. If an algorithm with a "prf" prefix is defined
    explicitly (such as prfsha1 or prfsha256), no implicit PRF algorithm based on
    the integrity algorithm is added to the proposal.
  • The pkcs11 plugin can now load leftcert certificates from a smartcard for a
    specific ipsec.conf conn section and cacert CA certificates for a specific ca
  • The load-tester plugin gained additional options for certificate generation
    and can load keys and multiple CA certificates from external files. It can
    install a dedicated outer IP address for each tunnel and tunnel initiation
    batches can be triggered and monitored externally using the
    ipsec load-tester tool.
  • PKCS#7 container parsing has been modularized, and the openssl plugin
    gained an alternative implementation to decrypt and verify such files.
    In contrast to our own DER parser, OpenSSL can handle BER files, which is
    required for interoperability of our scepclient with EJBCA.
  • Support for the proprietary IKEv1 fragmentation extension has been added.
    Fragments are always handled on receipt but only sent if supported by the peer
    and if enabled with the new fragmentation ipsec.conf option.
  • IKEv1 in charon can now parse certificates received in PKCS#7 containers and
    supports NAT traversal as used by Windows clients. Patches courtesy of
    Volker RĂ¼melin.
  • The new rdrand plugin provides a high quality / high performance random
    source using the Intel rdrand instruction found on Ivy Bridge processors.
  • The integration test environment (see source:testing/README) was updated and
    now uses KVM and reproducible guest images based on Debian.
  • The charon.ikesa_limit strongswan.conf option allows responders to limit
    the number of concurrently established IKE_SAs.
  • The charon daemon reloads the logger configuration from strongswan.conf
    if it receives a SIGHUP. Besides changing the configuration this allows to easily rotate
    log files created by file loggers without having to restart the daemon.
  • Resolving hosts by DNS name is now done in separate threads, which allows us
    to cancel these lookups (if getaddrinfo(3) is a cancellation point, anyway).
    The maximum number of threads can be configured in strongswan.conf.
  • Changed connections with auto=route are properly updated during ipsec update|reload.
  • Added missing XFRM marks for several functions in the kernel-netlink plugin.
  • The encoding of TLS extensions (elliptic_curves and signature_algorithms) was fixed.
