The Libreswan Project has released libreswan-3.14

This is a major feature and bugfix release. Upgrade with caution.

Support for two new RFC's was added, RFC 7383 IKEv2 Fragmentation
(fragmentation=|yes|no|force) and RFC 7619 IKEv2 Auth Null (authby=null,
leftid=%null). Support was added to IKEv2 to request confirmation
of a remote id (rightid=) using PAM via pam-authorize=yes|no. OCSP
support was re-added using the new keywords ocsp_enable= ocsp_strict=
ocsp_timeout= ocsp_uri= and ocsp_trust_name=. The IKE daemon now
uses libevent-2 and retransmission timers have been reduced from 20
seconds to 0.5 seconds (tunable by the new options retransmit-timeout=
and retransmit-interval=. A new binary "cavs" was added that can be
used to run NIST CAVS tests for FIPS validation (it is not required to
run libreswan). Various RFC test vectors were added and are run during
libreswan startup to confirm proper functioning of libreswan and the NSS
crypto library. FIPS algorithm restrictions are now enforced when running
on a FIPS enabled system. The last remnants of the weary FreeS/WAN X.509
code were replaced with native NSS functions (requiring at least NSS 3.16)
The logging options were renamed to the more logical logfile= and logtime=
and extended with logappend=yes|no - the old option names still work
for backward compatibility. The ipsec whack command was extended with a
few more options (--globalstatus --shuntstatus --purgeocsp --ddos-busy
--ddos-auto --ddos-unlimited and --deleteid) The ipsec command was
extended with --checknss which is run on startup to migrate the old NSS db
format to the new NSS sql format and with --checknflog to support adding
nflog pseudo-interfacaes for tcpdump (see also the per-conn nflog= option)


Additionally, many bugfixes and a few memory leaks were fixed, including
full INVALID_KE support, improved CERTREQ support, and improved error
handling on the IKEv2 Initial Exchanges. Interoperability with Windows,
SecureInside and iOS were improved via various fixes.
