Version 4.2.3 of strongSwan
Release Notes: The IKEv2 charon daemon now implements virtual IP address pools. The light version uses, for example, rightsourceip=10.3.0.0/22 to create a pool with 1022 addresses in volatile memory that are assigned on a first come, first served basis; whereas the advanced version uses rightsourceip=%poolname to reference an address pool in an SQLite or MySQL database which binds leases either statically or with a predefined timeout to a specific IKEv2 ID.
Other releases
Release Notes: This release fixes a severe security vulnerability (CVE-2013-2944) that existed in all versions 4.3.5 through 5.0.3. If the strongSwan "openssl" plugin was used for ECDSA signature verification, an empty, zeroed, or otherwise invalid signature was handled as a legitimate one.
Release Notes: The strongSwan Trusted Network Connect functionality supports all IETF Standard PA-TNC attributes and a new OS IMC/IMV pair using these attributes to transfer Linux or Android operating system information. Interoperability with Windows XP has been improved by supporting PKCS#7 certificate containers and legacy NAT traversal protocols. The test framework has been migrated from User Mode Linux to KVM, making it faster and more robust.
Release Notes: The leftsourceip option now accepts a comma separated combination of %config4, %config6, or fixed IP addresses to request from the responder. Likewise, the rightsourceip option accepts multiple explicitly specified or referenced named address pools. TPM-based remote attestation has been extended to verify the complete measurements done by the Linux Integrity Measurement Architecture (IMA). Reference hash values of up to 10'000 Linux system files are stored in an SQLite database.
Release Notes: The IKEv1 protocol was re-implemented from scratch by extending the successful IKEv2 code. The charon keying daemon now supports both protocols, which allowed the old IKEv1 pluto daemon to be removed. Support for the IKEv1 Aggressive and Hybrid Modes has been added.
Release Notes: An extended EAP-RADIUS interfaces allows one to enforce Session-Timeout attributes using RFC4478 repeated authentication, and acts upon RADIUS Dynamic Authorization extensions (RFC 5176). Currently supported are disconnect requests and CoA messages containing a Session-Timeout. The tnc-pdp plugin implements a RADIUS server interface allowing a strongSwan TNC server to act as a Policy Decision Point.
