-- initial support for rekeying CHILD_SAs using IKEv2. Currently
- perfect forward secrecy is not supported. The rekeying parameters
+- added dead peer detection which checks aliveness of remote peer if no
+ IKE or ESP traffic is received. Support for dpdaction, dpddelay???
+
+- Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2
+ would offer more possibilities for traffic selection, but the Linux kernel
+ currently does not support it. That's why we stick with these simple
+ ipsec.conf rules for now.
+
+- Initial NAT traversal support in IKEv2. Charon includes NAT detection
+ notify payloads to detect NAT routers between the peers. It switches
+ to port 4500, uses UDP encapsulated ESP packets, handles peer address
+ changes gracefully and sends keep alive message periodically.
+
+- Reimplemented IKE_SA state machine for charon, which allows simultaneous
+ rekeying, more shared code, cleaner design, proper retransmission
+ and a more extensible code base.
+
+strongswan-4.0.2
+----------------
+
+- The mixed PSK/RSA roadwarrior detection capability introduced by the
+ strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal
+ payloads by the responder right before any defined IKE Main Mode state had
+ been established. Although any form of bad proposal syntax was being correctly
+ detected by the payload parser, the subsequent error handler didn't check
+ the state pointer before logging current state information, causing an
+ immediate crash of the pluto keying daemon due to a NULL pointer.
+
+strongswan-4.0.1
+----------------
+
+- Added algorithm selection to charon: New default algorithms for
+ ike=aes128-sha-modp2048, as both daemons support it. The default
+ for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles
+ the ike/esp parameter the same way as pluto. As this syntax does
+ not allow specification of a pseudo random function, the same
+ algorithm as for integrity is used (currently sha/md5). Supported
+ algorithms for IKE:
+ Encryption: aes128, aes192, aes256
+ Integrity/PRF: md5, sha (using hmac)
+ DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192
+ and for ESP:
+ Encryption: aes128, aes192, aes256, 3des, blowfish128,
+ blowfish192, blowfish256
+ Integrity: md5, sha1
+ More IKE encryption algorithms will come after porting libcrypto into
+ libstrongswan.
+
+- initial support for rekeying CHILD_SAs using IKEv2. Currently no
+ perfect forward secrecy is used. The rekeying parameters rekey,
rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported
- when using IKEv2.
+ when using IKEv2. WARNING: charon currently is unable to handle
+ simultaneous rekeying. To avoid such a situation, use a large
+ rekeyfuzz, or even better, set rekey=no on one peer.
+
+- support for host2host, net2net, host2net (roadwarrior) tunnels
+ using predefined RSA certificates (see uml scenarios for
+ configuration examples).
- new build environment featuring autotools. Features such
as HTTP, LDAP and smartcard support may be enabled using
projects / strongswan.git / blobdiff
