Hello,
the first release candidate of strongSwan 4.5.1 is available for
download. Again a lot of new features have been added:
Trusted Network Connect (TNC)
-----------------------------
- Sansar Choinyambuu implemented the RFC 5793 Posture Broker Protocol
(PB) compatible with Trusted Network Connect (TNC). The TNCCS 2.0
protocol requires the tnccs_20, tnc_imc and tnc_imv plugins but does
not depend on the libtnc library. Any available IMV/IMC pairs
conforming to the Trusted Computing Group's TNC-IF-IMV/IMC 1.2
interface specification can be loaded via /etc/tnc_config.
http://www.strongswan.org/uml/testresults45rc/ikev2/rw-eap-tnc-20/
- Re-implemented the TNCCS 1.1 protocol by using the tnc_imc and tnc_imv
in place of the external libtnc library.
http://www.strongswan.org/uml/testresults45rc/ikev2/rw-eap-tnc-11-radius/
- The tnccs_dynamic plugin loaded on a TNC server in addition to the
tnccs_11 and tnccs_20 plugins, dynamically detects the IF-TNCCS
protocol version used by a TNC client and invokes an instance of
the corresponding protocol stack.

SQL Configuration Backend Extensions
------------------------------------
- IKE and ESP proposals can now be stored in an SQL database using a
new proposals table. The start_action field in the child_configs
tables allows the automatic starting or routing of connections stored
in an SQL database.

- The new certificate_authorities and certificate_distribution_points
tables make it possible to store CRL and OCSP Certificate Distribution
points in an SQL database.

Include statements in strongswan.conf
-------------------------------------
- The new 'include' statement allows to recursively include other files
in strongswan.conf. Existing sections and values are thereby extended
and replaced, respectively.
- Due to the changes in the parser for strongswan.conf, the
configuration syntax for the attr plugin has changed. Previously, it
was possible to specify multiple values of a specific attribute type
by adding multiple key/value pairs with the same key (e.g. dns) to
the plugins.attr section. Because values with the same key now
replace previously defined values this is not possible anymore. As an
alternative, multiple values can be specified by separating them with
a comma (e.g. dns = 1.2.3.4, 2.3.4.5).
Traffic Flow Confidentiality
----------------------------
- Traffic Flow Confidentiality padding supported with Linux 2.6.38 can
be used by the IKEv2 daemon. The ipsec.conf 'tfc' keyword pads all
packets to a given boundary, the special value '%mtu' pads all
packets to the path MTU.
Use of Linux Crypto API for IKE and other Userland Applications
---------------------------------------------------------------
- The new af-alg plugin can use various crypto primitives of the Linux
Crypto API using the AF_ALG interface introduced with 2.6.38. This
removes the need for additional userland implementations of symmetric
cipher, hash, hmac and xcbc algorithms.
INITIAL_CONTACT Notification
----------------------------
- The IKEv2 daemon supports the INITIAL_CONTACT notify as initiator and
responder. The notify is sent when initiating configurations with a
unique policy, set in ipsec.conf via the global 'uniqueids' option.
Conftest IKEv2 Conformance Testing Framework
--------------------------------------------
- The conftest conformance testing framework enables the IKEv2 stack to
performmany tests using a distinct tool and configuration frontend.
Various hooks can alter reserved bits, flags, add custom notifies and
proposals, reorder or drop messages and much more. It is enabled
using the --enable-conftest ./configure switch.
X.509 Certificate Constraints
-----------------------------
- The new libstrongswan constraints plugin provides advanced X.509
constraint checking. In additon to X.509 pathLen constraints, the
plugin checks for nameConstraints and certificatePolicies, including
policyMappings and policyConstraints. The x509 certificate plugin and
the pki tool have been enhanced to support these extensions. The new
left/rightcertpolicy ipsec.conf connection keywords take OIDs a peer
certificate must have.
- The left/rightauth ipsec.conf keywords accept values with a minimum
strength for trustchain public keys in bits, such as rsa-2048 or
ecdsa-256.
Support for Delta CRLs
----------------------
- The revocation and x509 libstrongswan plugins and the pki tool gained
basic support for delta CRLs.
Please have a look at the new feature and give us a feedback!
ETA for the stable 4.5.1 release is 1-2 weeks.
