4 - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no
5 IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear,
8 - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2
9 would offer more possibilities for traffic selection, but the Linux kernel
10 currently does not support it. That's why we stick with these simple
11 ipsec.conf rules for now.
13 - Initial NAT traversal support in IKEv2. Charon includes NAT detection
14 notify payloads to detect NAT routers between the peers. It switches
15 to port 4500, uses UDP encapsulated ESP packets, handles peer address
16 changes gracefully and sends keep alive message periodically.
18 - Reimplemented IKE_SA state machine for charon, which allows simultaneous
19 rekeying, more shared code, cleaner design, proper retransmission
20 and a more extensible code base.
22 - The mixed PSK/RSA roadwarrior detection capability introduced by the
23 strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal
24 payloads by the responder right before any defined IKE Main Mode state had
25 been established. Although any form of bad proposal syntax was being correctly
26 detected by the payload parser, the subsequent error handler didn't check
27 the state pointer before logging current state information, causing an
28 immediate crash of the pluto keying daemon due to a NULL pointer.
34 - Added algorithm selection to charon: New default algorithms for
35 ike=aes128-sha-modp2048, as both daemons support it. The default
36 for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles
37 the ike/esp parameter the same way as pluto. As this syntax does
38 not allow specification of a pseudo random function, the same
39 algorithm as for integrity is used (currently sha/md5). Supported
41 Encryption: aes128, aes192, aes256
42 Integrity/PRF: md5, sha (using hmac)
43 DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192
45 Encryption: aes128, aes192, aes256, 3des, blowfish128,
46 blowfish192, blowfish256
48 More IKE encryption algorithms will come after porting libcrypto into
51 - initial support for rekeying CHILD_SAs using IKEv2. Currently no
52 perfect forward secrecy is used. The rekeying parameters rekey,
53 rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported
54 when using IKEv2. WARNING: charon currently is unable to handle
55 simultaneous rekeying. To avoid such a situation, use a large
56 rekeyfuzz, or even better, set rekey=no on one peer.
58 - support for host2host, net2net, host2net (roadwarrior) tunnels
59 using predefined RSA certificates (see uml scenarios for
60 configuration examples).
62 - new build environment featuring autotools. Features such
63 as HTTP, LDAP and smartcard support may be enabled using
64 the ./configure script. Changing install directories
65 is possible, too. See ./configure --help for more details.
67 - better integration of charon with ipsec starter, which allows
68 (almost) transparent operation with both daemons. charon
69 handles ipsec commands up, down, status, statusall, listall,
70 listcerts and allows proper load, reload and delete of connections
76 - initial support of the IKEv2 protocol. Connections in
77 ipsec.conf designated by keyexchange=ikev2 are negotiated
78 by the new IKEv2 charon keying daemon whereas those marked
79 by keyexchange=ikev1 or the default keyexchange=ike are
80 handled thy the IKEv1 pluto keying daemon. Currently only
81 a limited subset of functions are available with IKEv2
82 (Default AES encryption, authentication based on locally
83 imported X.509 certificates, unencrypted private RSA keys
84 in PKCS#1 file format, limited functionality of the ipsec
91 - the dynamic iptables rules from the _updown_x509 template
92 for KLIPS and the _updown_policy template for NETKEY have
93 been merged into the default _updown script. The existing
94 left|rightfirewall keyword causes the automatic insertion
95 and deletion of ACCEPT rules for tunneled traffic upon
96 the successful setup and teardown of an IPsec SA, respectively.
97 left|rightfirwall can be used with KLIPS under any Linux 2.4
98 kernel or with NETKEY under a Linux kernel version >= 2.6.16
99 in conjuction with iptables >= 1.3.5. For NETKEY under a Linux
100 kernel version < 2.6.16 which does not support IPsec policy
101 matching yet, please continue to use a copy of the _updown_espmark
102 template loaded via the left|rightupdown keyword.
104 - a new left|righthostaccess keyword has been introduced which
105 can be used in conjunction with left|rightfirewall and the
106 default _updown script. By default leftfirewall=yes inserts
107 a bi-directional iptables FORWARD rule for a local client network
108 with a netmask different from 255.255.255.255 (single host).
109 This does not allow to access the VPN gateway host via its
110 internal network interface which is part of the client subnet
111 because an iptables INPUT and OUTPUT rule would be required.
112 lefthostaccess=yes will cause this additional ACCEPT rules to
115 - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal
116 payload is preparsed in order to find out whether the roadwarrior
117 requests PSK or RSA so that a matching connection candidate can
124 - the new _updown_policy template allows ipsec policy based
125 iptables firewall rules. Required are iptables version
126 >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes
127 the _updown_espmark template, so that no INPUT mangle rules
128 are required any more.
130 - added support of DPD restart mode
132 - ipsec starter now allows the use of wildcards in include
133 statements as e.g. in "include /etc/my_ipsec/*.conf".
134 Patch courtesy of Matthias Haas.
136 - the Netscape OID 'employeeNumber' is now recognized and can be
137 used as a Relative Distinguished Name in certificates.
143 - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec
144 command and not of ipsec setup any more.
146 - ipsec starter now supports AH authentication in conjunction with
147 ESP encryption. AH authentication is configured in ipsec.conf
148 via the auth=ah parameter.
150 - The command ipsec scencrypt|scdecrypt <args> is now an alias for
151 ipsec whack --scencrypt|scdecrypt <args>.
153 - get_sa_info() now determines for the native netkey IPsec stack
154 the exact time of the last use of an active eroute. This information
155 is used by the Dead Peer Detection algorithm and is also displayed by
156 the ipsec status command.
162 - running under the native Linux 2.6 IPsec stack, the function
163 get_sa_info() is called by ipsec auto --status to display the current
164 number of transmitted bytes per IPsec SA.
166 - get_sa_info() is also used by the Dead Peer Detection process to detect
167 recent ESP activity. If ESP traffic was received from the peer within
168 the last dpd_delay interval then no R_Y_THERE notification must be sent.
170 - strongSwan now supports the Relative Distinguished Name "unstructuredName"
171 in ID_DER_ASN1_DN identities. The following notations are possible:
173 rightid="unstructuredName=John Doe"
174 rightid="UN=John Doe"
176 - fixed a long-standing bug which caused PSK-based roadwarrior connections
177 to segfault in the function id.c:same_id() called by keys.c:get_secret()
178 if an FQDN, USER_FQDN, or Key ID was defined, as in the following example.
185 - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall).
187 - ipsec starter didn't set host_addr and client.addr ports in whack msg.
189 - in order to guarantee backwards-compatibility with the script-based
190 auto function (e.g. auto --replace), the ipsec starter scripts stores
191 the defaultroute information in the temporary file /var/run/ipsec.info.
193 - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH
194 Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config
197 - the ipsec starter now also recognizes the parameters authby=never and
198 type=passthrough|pass|drop|reject.
204 - ipsec starter now supports the also parameter which allows
205 a modular structure of the connection definitions. Thus
206 "ipsec start" is now ready to replace "ipsec setup".
212 - Mathieu Lafon's popular ipsec starter tool has been added to the
213 strongSwan distribution. Many thanks go to Stephan Scholz from astaro
214 for his integration work. ipsec starter is a C program which is going
215 to replace the various shell and awk starter scripts (setup, _plutoload,
216 _plutostart, _realsetup, _startklips, _confread, and auto). Since
217 ipsec.conf is now parsed only once, the starting of multiple tunnels is
218 accelerated tremedously.
220 - Added support of %defaultroute to the ipsec starter. If the IP address
221 changes, a HUP signal to the ipsec starter will automatically
222 reload pluto's connections.
224 - moved most compile time configurations from pluto/Makefile to
225 Makefile.inc by defining the options USE_LIBCURL, USE_LDAP,
226 USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE.
228 - removed the ipsec verify and ipsec newhostkey commands
230 - fixed some 64-bit issues in formatted print statements
232 - The scepclient functionality implementing the Simple Certificate
233 Enrollment Protocol (SCEP) is nearly complete but hasn't been
240 - CA certicates are now automatically loaded from a smartcard
241 or USB crypto token and appear in the ipsec auto --listcacerts
248 - when using "ipsec whack --scencrypt <data>" with a PKCS#11
249 library that does not support the C_Encrypt() Cryptoki
250 function (e.g. OpenSC), the RSA encryption is done in
251 software using the public key fetched from the smartcard.
253 - The scepclient function now allows to define the
254 validity of a self-signed certificate using the --days,
255 --startdate, and --enddate options. The default validity
256 has been changed from one year to five years.
262 - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11
263 interface to other applications for RSA encryption and decryption
264 via the whack interface. Notation:
266 ipsec whack --scencrypt <data>
267 [--inbase 16|hex|64|base64|256|text|ascii]
268 [--outbase 16|hex|64|base64|256|text|ascii]
271 ipsec whack --scdecrypt <data>
272 [--inbase 16|hex|64|base64|256|text|ascii]
273 [--outbase 16|hex|64|base64|256|text|ascii]
276 The default setting for inbase and outbase is hex.
278 The new proxy interface can be used for securing symmetric
279 encryption keys required by the cryptoloop or dm-crypt
280 disk encryption schemes, especially in the case when
281 pkcs11keepstate=yes causes pluto to lock the pkcs11 slot
284 - if the file /etc/ipsec.secrets is lacking during the startup of
285 pluto then the root-readable file /etc/ipsec.d/private/myKey.der
286 containing a 2048 bit RSA private key and a matching self-signed
287 certificate stored in the file /etc/ipsec.d/certs/selfCert.der
288 is automatically generated by calling the function
290 ipsec scepclient --out pkcs1 --out cert-self
292 scepclient was written by Jan Hutter and Martin Willi, students
293 at the University of Applied Sciences in Rapperswil, Switzerland.
299 - the current extension of the PKCS#7 framework introduced
300 a parsing error in PKCS#7 wrapped X.509 certificates that are
301 e.g. transmitted by Windows XP when multi-level CAs are used.
302 the parsing syntax has been fixed.
304 - added a patch by Gerald Richter which tolerates multiple occurrences
305 of the ipsec0 interface when using KLIPS.
311 - with gawk-3.1.4 the word "default2 has become a protected
312 keyword for use in switch statements and cannot be used any
313 more in the strongSwan scripts. This problem has been
314 solved by renaming "default" to "defaults" and "setdefault"
315 in the scripts _confread and auto, respectively.
317 - introduced the parameter leftsendcert with the values
319 always|yes (the default, always send a cert)
320 ifasked (send the cert only upon a cert request)
321 never|no (never send a cert, used for raw RSA keys and
324 - fixed the initialization of the ESP key length to a default of
325 128 bits in the case that the peer does not send a key length
326 attribute for AES encryption.
328 - applied Herbert Xu's uniqueIDs patch
330 - applied Herbert Xu's CLOEXEC patches
336 - CRLs can now be cached also in the case when the issuer's
337 certificate does not contain a subjectKeyIdentifier field.
338 In that case the subjectKeyIdentifier is computed by pluto as the
339 160 bit SHA-1 hash of the issuer's public key in compliance
340 with section 4.2.1.2 of RFC 3280.
342 - Fixed a bug introduced by strongswan-2.5.1 which eliminated
343 not only multiple Quick Modes of a given connection but also
344 multiple connections between two security gateways.
350 - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute
351 installed either by setting auto=route in ipsec.conf or by
352 a connection put into hold, generates an XFRM_AQUIRE event
353 for each packet that wants to use the not-yet exisiting
354 tunnel. Up to now each XFRM_AQUIRE event led to an entry in
355 the Quick Mode queue, causing multiple IPsec SA to be
356 established in rapid succession. Starting with strongswan-2.5.1
357 only a single IPsec SA is established per host-pair connection.
359 - Right after loading the PKCS#11 module, all smartcard slots are
360 searched for certificates. The result can be viewed using
363 ipsec auto --listcards
365 The certificate objects found in the slots are numbered
366 starting with #1, #2, etc. This position number can be used to address
367 certificates (leftcert=%smartcard) and keys (: PIN %smartcard)
368 in ipsec.conf and ipsec.secrets, respectively:
370 %smartcard (selects object #1)
371 %smartcard#1 (selects object #1)
372 %smartcard#3 (selects object #3)
374 As an alternative the existing retrieval scheme can be used:
376 %smartcard:45 (selects object with id=45)
377 %smartcard0 (selects first object in slot 0)
378 %smartcard4:45 (selects object in slot 4 with id=45)
380 - Depending on the settings of CKA_SIGN and CKA_DECRYPT
381 private key flags either C_Sign() or C_Decrypt() is used
382 to generate a signature.
384 - The output buffer length parameter siglen in C_Sign()
385 is now initialized to the actual size of the output
386 buffer prior to the function call. This fixes the
387 CKR_BUFFER_TOO_SMALL error that could occur when using
388 the OpenSC PKCS#11 module.
390 - Changed the initialization of the PKCS#11 CK_MECHANISM in
391 C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }.
393 - Refactored the RSA public/private key code and transferred it
394 from keys.c to the new pkcs1.c file as a preparatory step
395 towards the release of the SCEP client.
401 - The loading of a PKCS#11 smartcard library module during
402 runtime does not require OpenSC library functions any more
403 because the corresponding code has been integrated into
404 smartcard.c. Also the RSAREF pkcs11 header files have been
405 included in a newly created pluto/rsaref directory so that
406 no external include path has to be defined any longer.
408 - A long-awaited feature has been implemented at last:
409 The local caching of CRLs fetched via HTTP or LDAP, activated
410 by the parameter cachecrls=yes in the config setup section
411 of ipsec.conf. The dynamically fetched CRLs are stored under
412 a unique file name containing the issuer's subjectKeyID
413 in /etc/ipsec.d/crls.
415 - Applied a one-line patch courtesy of Michael Richardson
416 from the Openswan project which fixes the kernel-oops
417 in KLIPS when an snmp daemon is running on the same box.
423 - Eliminated null length CRL distribution point strings.
425 - Fixed a trust path evaluation bug introduced with 2.4.3
431 - Improved the joint OCSP / CRL revocation policy.
432 OCSP responses have precedence over CRL entries.
434 - Introduced support of CRLv2 reason codes.
436 - Fixed a bug with key-pad equipped readers which caused
437 pluto to prompt for the pin via the console when the first
438 occasion to enter the pin via the key-pad was missed.
440 - When pluto is built with LDAP_V3 enabled, the library
441 liblber required by newer versions of openldap is now
448 - Added the _updown_espmark template which requires all
449 incoming ESP traffic to be marked with a default mark
452 - Introduced the pkcs11keepstate parameter in the config setup
453 section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11
454 session and login states are kept as long as possible during
455 the lifetime of pluto. This means that a PIN entry via a key
456 pad has to be done only once.
458 - Introduced the pkcs11module parameter in the config setup
459 section of ipsec.conf which specifies the PKCS#11 module
460 to be used with smart cards. Example:
462 pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo
464 - Added support of smartcard readers equipped with a PIN pad.
466 - Added patch by Jay Pfeifer which detects when netkey
467 modules have been statically built into the Linux 2.6 kernel.
469 - Added two patches by Herbert Xu. The first uses ip xfrm
470 instead of setkey to flush the IPsec policy database. The
471 second sets the optional flag in inbound IPComp SAs only.
473 - Applied Ulrich Weber's patch which fixes an interoperability
474 problem between native IPsec and KLIPS systems caused by
475 setting the replay window to 32 instead of 0 for ipcomp.
481 - Fixed a bug which caused an unwanted Mode Config request
482 to be initiated in the case where "right" was used to denote
483 the local side in ipsec.conf and "left" the remote side,
484 contrary to the recommendation that "right" be remote and
491 - updated Vendor ID to strongSwan-2.4.0
493 - updated copyright statement to include David Buechi and
500 - strongSwan now communicates with attached smartcards and
501 USB crypto tokens via the standardized PKCS #11 interface.
502 By default the OpenSC library from www.opensc.org is used
503 but any other PKCS#11 library could be dynamically linked.
504 strongSwan's PKCS#11 API was implemented by David Buechi
505 and Michael Meier, both graduates of the Zurich University
506 of Applied Sciences in Winterthur, Switzerland.
508 - When a %trap eroute is triggered by an outgoing IP packet
509 then the native IPsec stack of the Linux 2.6 kernel [often/
510 always?] returns an XFRM_ACQUIRE message with an undefined
511 protocol family field and the connection setup fails.
512 As a workaround IPv4 (AF_INET) is now assumed.
514 - the results of the UML test scenarios are now enhanced
515 with block diagrams of the virtual network topology used
516 in a particular test.
522 - fixed IV used to decrypt informational messages.
523 This bug was introduced with Mode Config functionality.
525 - fixed NCP Vendor ID.
527 - undid one of Ulrich Weber's maximum udp size patches
528 because it caused a segmentation fault with NAT-ed
531 - added UML scenarios wildcards and attr-cert which
532 demonstrate the implementation of IPsec policies based
533 on wildcard parameters contained in Distinguished Names and
534 on X.509 attribute certificates, respectively.
540 - Added basic Mode Config functionality
542 - Added Mathieu Lafon's patch which upgrades the status of
543 the NAT-Traversal implementation to RFC 3947.
545 - The _startklips script now also loads the xfrm4_tunnel
548 - Added Ulrich Weber's netlink replay window size and
549 maximum udp size patches.
551 - UML testing now uses the Linux 2.6.10 UML kernel by default.
557 - Eric Marchionni and Patrik Rayo, both recent graduates from
558 the Zuercher Hochschule Winterthur in Switzerland, created a
559 User-Mode-Linux test setup for strongSwan. For more details
560 please read the INSTALL and README documents in the testing
563 - Full support of group attributes based on X.509 attribute
564 certificates. Attribute certificates can be generated
565 using the openac facility. For more details see
569 The group attributes can be used in connection definitions
570 in order to give IPsec access to specific user groups.
571 This is done with the new parameter left|rightgroups as in
573 rightgroups="Research, Sales"
575 giving access to users possessing the group attributes
576 Research or Sales, only.
578 - In Quick Mode clients with subnet mask /32 are now
579 coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should
580 fix rekeying problems with the SafeNet/SoftRemote and NCP
581 Secure Entry Clients.
583 - Changed the defaults of the ikelifetime and keylife parameters
584 to 3h and 1h, respectively. The maximum allowable values are
585 now both set to 24 h.
587 - Suppressed notification wars between two IPsec peers that
588 could e.g. be triggered by incorrect ISAKMP encryption.
590 - Public RSA keys can now have identical IDs if either the
591 issuing CA or the serial number is different. The serial
592 number of a certificate is now shown by the command
594 ipsec auto --listpubkeys
600 - Added Tuomo Soini's sourceip feature which allows a strongSwan
601 roadwarrior to use a fixed Virtual IP (see README section 2.6)
602 and reduces the well-known four tunnel case on VPN gateways to
603 a single tunnel definition (see README section 2.4).
605 - Fixed a bug occuring with NAT-Traversal enabled when the responder
606 suddenly turns initiator and the initiator cannot find a matching
607 connection because of the floated IKE port 4500.
609 - Removed misleading ipsec verify command from barf.
611 - Running under the native IP stack, ipsec --version now shows
612 the Linux kernel version (courtesy to the Openswan project).
618 - Introduced the ipsec auto --listalgs monitoring command which lists
619 all currently registered IKE and ESP algorithms.
621 - Fixed a bug in the ESP algorithm selection occuring when the strict flag
622 is set and the first proposed transform does not match.
624 - Fixed another deadlock in the use of the lock_certs_and_keys() mutex,
625 occuring when a smartcard is present.
627 - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event.
629 - Fixed the printing of the notification names (null)
631 - Applied another of Herbert Xu's Netlink patches.
637 - Support of Dead Peer Detection. The connection parameter
641 activates DPD for the given connection.
643 - The default Opportunistic Encryption (OE) policy groups are not
644 automatically included anymore. Those wishing to activate OE can include
645 the policy group with the following statement in ipsec.conf:
647 include /etc/ipsec.d/examples/oe.conf
649 The default for [right|left]rsasigkey is now set to %cert.
651 - strongSwan now has a Vendor ID of its own which can be activated
652 using the compile option VENDORID
654 - Applied Herbert Xu's patch which sets the compression algorithm correctly.
656 - Applied Herbert Xu's patch fixing an ESPINUDP problem
658 - Applied Herbert Xu's patch setting source/destination port numbers.
660 - Reapplied one of Herbert Xu's NAT-Traversal patches which got
661 lost during the migration from SuperFreeS/WAN.
663 - Fixed a deadlock in the use of the lock_certs_and_keys() mutex.
665 - Fixed the unsharing of alg parameters when instantiating group
672 - Thomas Walpuski made me aware of a potential DoS attack via
673 a PKCS#7-wrapped certificate bundle which could overwrite valid CA
674 certificates in Pluto's authority certificate store. This vulnerability
675 was fixed by establishing trust in CA candidate certificates up to a
676 trusted root CA prior to insertion into Pluto's chained list.
678 - replaced the --assign option by the -v option in the auto awk script
679 in order to make it run with mawk under debian/woody.
685 - Split of the status information between ipsec auto --status (concise)
686 and ipsec auto --statusall (verbose). Both commands can be used with
687 an optional connection selector:
689 ipsec auto --status[all] <connection_name>
691 - Added the description of X.509 related features to the ipsec_auto(8)
694 - Hardened the ASN.1 parser in debug mode, especially the printing
695 of malformed distinguished names.
697 - The size of an RSA public key received in a certificate is now restricted to
699 512 bits <= modulus length <= 8192 bits.
701 - Fixed the debug mode enumeration.
707 - Fixed another PKCS#7 vulnerability which could lead to an
708 endless loop while following the X.509 trust chain.
714 - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski
715 that accepted end certificates having identical issuer and subject
716 distinguished names in a multi-tier X.509 trust chain.
722 - Removed all remaining references to ipsec_netlink.h in KLIPS.
728 - The new "ca" section allows to define the following parameters:
731 cacert=koolCA.pem # cacert of kool CA
732 ocspuri=http://ocsp.kool.net:8001 # ocsp server
733 ldapserver=ldap.kool.net # default ldap server
734 crluri=http://www.kool.net/kool.crl # crl distribution point
735 crluri2="ldap:///O=Kool, C= .." # crl distribution point #2
736 auto=add # add, ignore
738 The ca definitions can be monitored via the command
740 ipsec auto --listcainfos
742 - Fixed cosmetic corruption of /proc filesystem by integrating
743 D. Hugh Redelmeier's freeswan-2.06 kernel fixes.
749 - Added support for the 818043 NAT-Traversal update of Microsoft's
750 Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode.
752 - A symbolic link to libcrypto is now added in the kernel sources
753 during kernel compilation
755 - Fixed a couple of 64 bit issues (mostly casts to int).
756 Thanks to Ken Bantoft who checked my sources on a 64 bit platform.
758 - Replaced s[n]printf() statements in the kernel by ipsec_snprintf().
759 Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro
760 of the FreeS/WAN team who solved this problem with the 2.4.25 kernel.
766 - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName
767 certificate extension which contains no generalName item) can cause
768 a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has
769 been hardened to make it more robust against malformed ASN.1 objects.
771 - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native
772 Linux 2.6 IPsec stack.
778 - based on freeswan-2.04, x509-1.5.3, nat-0.6c, alg-0.8.1rc12
