+- The new aesni plugin provides CBC, CTR, XCBC, CMAC, CCM and GCM crypto
+ primitives for AES-128/192/256. The plugin requires AES-NI and PCLMULQDQ
+ instructions and works on both x86 and x64 architectures. It provides
+ superior crypto performance in userland without any external libraries.
+
+
+strongswan-5.3.0
+----------------
+
+- Added support for IKEv2 make-before-break reauthentication. By using a global
+ CHILD_SA reqid allocation mechanism, charon supports overlapping CHILD_SAs.
+ This allows the use of make-before-break instead of the previously supported
+ break-before-make reauthentication, avoiding connectivity gaps during that
+ procedure. As the new mechanism may fail with peers not supporting it (such
+ as any previous strongSwan release) it must be explicitly enabled using
+ the charon.make_before_break strongswan.conf option.
+
+- Support for "Signature Authentication in IKEv2" (RFC 7427) has been added.
+ This allows the use of stronger hash algorithms for public key authentication.
+ By default, signature schemes are chosen based on the strength of the
+ signature key, but specific hash algorithms may be configured in leftauth.
+
+- Key types and hash algorithms specified in rightauth are now also checked
+ against IKEv2 signature schemes. If such constraints are used for certificate
+ chain validation in existing configurations, in particular with peers that
+ don't support RFC 7427, it may be necessary to disable this feature with the
+ charon.signature_authentication_constraints setting, because the signature
+ scheme used in classic IKEv2 public key authentication may not be strong
+ enough.
+
+- The new connmark plugin allows a host to bind conntrack flows to a specific
+ CHILD_SA by applying and restoring the SA mark to conntrack entries. This
+ allows a peer to handle multiple transport mode connections coming over the
+ same NAT device for client-initiated flows. A common use case is to protect
+ L2TP/IPsec, as supported by some systems.
+
+- The forecast plugin can forward broadcast and multicast messages between
+ connected clients and a LAN. For CHILD_SA using unique marks, it sets up
+ the required Netfilter rules and uses a multicast/broadcast listener that
+ forwards such messages to all connected clients. This plugin is designed for
+ Windows 7 IKEv2 clients, which announces its services over the tunnel if the
+ negotiated IPsec policy allows it.
+
+- For the vici plugin a Python Egg has been added to allow Python applications
+ to control or monitor the IKE daemon using the VICI interface, similar to the
+ existing ruby gem. The Python library has been contributed by Björn Schuberg.
+
+- EAP server methods now can fulfill public key constraints, such as rightcert
+ or rightca. Additionally, public key and signature constraints can be
+ specified for EAP methods in the rightauth keyword. Currently the EAP-TLS and
+ EAP-TTLS methods provide verification details to constraints checking.
+
+- Upgrade of the BLISS post-quantum signature algorithm to the improved BLISS-B
+ variant. Can be used in conjunction with the SHA256, SHA384 and SHA512 hash
+ algorithms with SHA512 being the default.
+
+- The IF-IMV 1.4 interface now makes the IP address of the TNC access requestor
+ as seen by the TNC server available to all IMVs. This information can be
+ forwarded to policy enforcement points (e.g. firewalls or routers).
+
+- The new mutual tnccs-20 plugin parameter activates mutual TNC measurements
+ in PB-TNC half-duplex mode between two endpoints over either a PT-EAP or
+ PT-TLS transport medium.
+
+
+strongswan-5.2.2
+----------------
+
+- Fixed a denial-of-service vulnerability triggered by an IKEv2 Key Exchange
+ payload that contains the Diffie-Hellman group 1025. This identifier was
+ used internally for DH groups with custom generator and prime. Because
+ these arguments are missing when creating DH objects based on the KE payload
+ an invalid pointer dereference occurred. This allowed an attacker to crash
+ the IKE daemon with a single IKE_SA_INIT message containing such a KE
+ payload. The vulnerability has been registered as CVE-2014-9221.
+
+- The left/rightid options in ipsec.conf, or any other identity in strongSwan,
+ now accept prefixes to enforce an explicit type, such as email: or fqdn:.
+ Note that no conversion is done for the remaining string, refer to
+ ipsec.conf(5) for details.
+
+- The post-quantum Bimodal Lattice Signature Scheme (BLISS) can be used as
+ an IKEv2 public key authentication method. The pki tool offers full support
+ for the generation of BLISS key pairs and certificates.
+
+- Fixed mapping of integrity algorithms negotiated for AH via IKEv1. This could
+ cause interoperability issues when connecting to older versions of charon.
+
+
+strongswan-5.2.1
+----------------
+
+- The new charon-systemd IKE daemon implements an IKE daemon tailored for use
+ with systemd. It avoids the dependency on ipsec starter and uses swanctl
+ as configuration backend, building a simple and lightweight solution. It
+ supports native systemd journal logging.
+
+- Support for IKEv2 fragmentation as per RFC 7383 has been added. Like IKEv1
+ fragmentation it can be enabled by setting fragmentation=yes in ipsec.conf.
+
+- Support of the TCG TNC IF-M Attribute Segmentation specification proposal.
+ All attributes can be segmented. Additionally TCG/SWID Tag, TCG/SWID Tag ID
+ and IETF/Installed Packages attributes can be processed incrementally on a
+ per segment basis.
+
+- The new ext-auth plugin calls an external script to implement custom IKE_SA
+ authorization logic, courtesy of Vyronas Tsingaras.
+
+- For the vici plugin a ruby gem has been added to allow ruby applications
+ to control or monitor the IKE daemon. The vici documentation has been updated
+ to include a description of the available operations and some simple examples
+ using both the libvici C interface and the ruby gem.
+
+
+strongswan-5.2.0
+----------------
+
+- strongSwan has been ported to the Windows platform. Using a MinGW toolchain,
+ many parts of the strongSwan codebase run natively on Windows 7 / 2008 R2
+ and newer releases. charon-svc implements a Windows IKE service based on
+ libcharon, the kernel-iph and kernel-wfp plugins act as networking and IPsec
+ backend on the Windows platform. socket-win provides a native IKE socket
+ implementation, while winhttp fetches CRL and OCSP information using the
+ WinHTTP API.
+
+- The new vici plugin provides a Versatile IKE Configuration Interface for
+ charon. Using the stable IPC interface, external applications can configure,
+ control and monitor the IKE daemon. Instead of scripting the ipsec tool
+ and generating ipsec.conf, third party applications can use the new interface
+ for more control and better reliability.
+
+- Built upon the libvici client library, swanctl implements the first user of
+ the VICI interface. Together with a swanctl.conf configuration file,
+ connections can be defined, loaded and managed. swanctl provides a portable,
+ complete IKE configuration and control interface for the command line.
+ The first six swanctl example scenarios have been added.
+
+- The SWID IMV implements a JSON-based REST API which allows the exchange
+ of SWID tags and Software IDs with the strongTNC policy manager.
+
+- The SWID IMC can extract all installed packages from the dpkg (Debian,
+ Ubuntu, Linux Mint etc.), rpm (Fedora, RedHat, OpenSUSE, etc.), or
+ pacman (Arch Linux, Manjaro, etc.) package managers, respectively, using the
+ swidGenerator (https://github.com/strongswan/swidGenerator) which generates
+ SWID tags according to the new ISO/IEC 19770-2:2014 standard.
+
+- All IMVs now share the access requestor ID, device ID and product info
+ of an access requestor via a common imv_session object.
+
+- The Attestation IMC/IMV pair supports the IMA-NG measurement format
+ introduced with the Linux 3.13 kernel.
+
+- The aikgen tool generates an Attestation Identity Key bound to a TPM.
+
+- Implemented the PT-EAP transport protocol (RFC 7171) for Trusted Network
+ Connect.
+
+- The ipsec.conf replay_window option defines connection specific IPsec replay
+ windows. Original patch courtesy of Zheng Zhong and Christophe Gouault from
+ 6Wind.
+
+
strongswan-5.1.3
----------------
+- Fixed an authentication bypass vulnerability triggered by rekeying an
+ unestablished IKEv2 SA while it gets actively initiated. This allowed an
+ attacker to trick a peer's IKE_SA state to established, without the need to
+ provide any valid authentication credentials. The vulnerability has been
+ registered as CVE-2014-2338.
+
- The acert plugin evaluates X.509 Attribute Certificates. Group membership
information encoded as strings can be used to fulfill authorization checks
defined with the rightgroups option. Attribute Certificates can be loaded
using the --acert subcommand, while the --print command supports the ac type.
The openac utility has been removed in favor of the new pki functionality.
+- The libtls TLS 1.2 implementation as used by EAP-(T)TLS and other protocols
+ has been extended by AEAD mode support, currently limited to AES-GCM.
