4 - strongSwan now interoperates with the NCP Secure Entry Client,
5 the Shrew Soft VPN Client, and the Cisco VPN client, doing both
8 - UNITY attributes are now recognized and UNITY_BANNER is set
15 - IKEv1: Support for extended authentication (XAUTH) in combination
16 with ISAKMP Main Mode RSA or PSK authentication. Both client and
17 server side were implemented. Handling of user credentials can
18 be done by a run-time loadable XAUTH module. By default user
19 credentials are stored in ipsec.secrets.
21 - IKEv2: Support for reauthentication when rekeying
23 - IKEv2: Support for transport mode
25 - fixed a lot of bugs related to byte order
27 - various other bugfixes
33 - IKEv1: Implementation of ModeConfig push mode via the new connection
34 keyword modeconfig=push allows interoperability with Cisco VPN gateways.
36 - IKEv1: The command ipsec statusall now shows "DPD active" for all
37 ISAKMP SAs that are under active Dead Peer Detection control.
39 - IKEv2: Charon's logging and debugging framework has been completely rewritten.
40 Instead of logger, special printf() functions are used to directly
41 print objects like hosts (%H) identifications (%D), certificates (%Q),
42 etc. The number of debugging levels have been reduced to:
44 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private)
46 The debugging levels can either be specified statically in ipsec.conf as
49 charondebug="lib 1, cfg 3, net 2"
51 or changed at runtime via stroke as
53 ipsec stroke loglevel cfg 2
59 - Implemented full support for IPv6-in-IPv6 tunnels.
61 - Added configuration options for dead peer detection in IKEv2. dpd_action
62 types "clear", "hold" and "restart" are supported. The dpd_timeout
63 value is not used, as the normal retransmission policy applies to
64 detect dead peers. The dpd_delay parameter enables sending of empty
65 informational message to detect dead peers in case of inactivity.
67 - Added support for preshared keys in IKEv2. PSK keys configured in
68 ipsec.secrets are loaded. The authby parameter specifies the authentication
69 method to authentificate ourself, the other peer may use PSK or RSA.
71 - Changed retransmission policy to respect the keyingtries parameter.
73 - Added private key decryption. PEM keys encrypted with AES-128/192/256
74 or 3DES are supported.
76 - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to
79 - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates
80 signed with such a hash algorithm.
82 - Added initial support for updown scripts. The actions up-host/client and
83 down-host/client are executed. The leftfirewall=yes parameter
84 uses the default updown script to insert dynamic firewall rules, a custom
85 updown script may be specified with the leftupdown parameter.
91 - Added support for the auto=route ipsec.conf parameter and the
92 ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and
93 CHILD_SAs dynamically on demand when traffic is detected by the
96 - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter.
97 As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only
98 new keys are generated using perfect forward secrecy. An optional flag
99 which enforces reauthentication will be implemented later.
101 - "sha" and "sha1" are now treated as synonyms in the ike= and esp=
102 algorithm configuration statements.
108 - Full X.509 certificate trust chain verification has been implemented.
109 End entity certificates can be exchanged via CERT payloads. The current
110 default is leftsendcert=always, since CERTREQ payloads are not supported
111 yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls.
113 - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2
114 would offer more possibilities for traffic selection, but the Linux kernel
115 currently does not support it. That's why we stick with these simple
116 ipsec.conf rules for now.
118 - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no
119 IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear,
122 - Initial NAT traversal support in IKEv2. Charon includes NAT detection
123 notify payloads to detect NAT routers between the peers. It switches
124 to port 4500, uses UDP encapsulated ESP packets, handles peer address
125 changes gracefully and sends keep alive message periodically.
127 - Reimplemented IKE_SA state machine for charon, which allows simultaneous
128 rekeying, more shared code, cleaner design, proper retransmission
129 and a more extensible code base.
131 - The mixed PSK/RSA roadwarrior detection capability introduced by the
132 strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal
133 payloads by the responder right before any defined IKE Main Mode state had
134 been established. Although any form of bad proposal syntax was being correctly
135 detected by the payload parser, the subsequent error handler didn't check
136 the state pointer before logging current state information, causing an
137 immediate crash of the pluto keying daemon due to a NULL pointer.
143 - Added algorithm selection to charon: New default algorithms for
144 ike=aes128-sha-modp2048, as both daemons support it. The default
145 for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles
146 the ike/esp parameter the same way as pluto. As this syntax does
147 not allow specification of a pseudo random function, the same
148 algorithm as for integrity is used (currently sha/md5). Supported
150 Encryption: aes128, aes192, aes256
151 Integrity/PRF: md5, sha (using hmac)
152 DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192
154 Encryption: aes128, aes192, aes256, 3des, blowfish128,
155 blowfish192, blowfish256
157 More IKE encryption algorithms will come after porting libcrypto into
160 - initial support for rekeying CHILD_SAs using IKEv2. Currently no
161 perfect forward secrecy is used. The rekeying parameters rekey,
162 rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported
163 when using IKEv2. WARNING: charon currently is unable to handle
164 simultaneous rekeying. To avoid such a situation, use a large
165 rekeyfuzz, or even better, set rekey=no on one peer.
167 - support for host2host, net2net, host2net (roadwarrior) tunnels
168 using predefined RSA certificates (see uml scenarios for
169 configuration examples).
171 - new build environment featuring autotools. Features such
172 as HTTP, LDAP and smartcard support may be enabled using
173 the ./configure script. Changing install directories
174 is possible, too. See ./configure --help for more details.
176 - better integration of charon with ipsec starter, which allows
177 (almost) transparent operation with both daemons. charon
178 handles ipsec commands up, down, status, statusall, listall,
179 listcerts and allows proper load, reload and delete of connections
186 - initial support of the IKEv2 protocol. Connections in
187 ipsec.conf designated by keyexchange=ikev2 are negotiated
188 by the new IKEv2 charon keying daemon whereas those marked
189 by keyexchange=ikev1 or the default keyexchange=ike are
190 handled thy the IKEv1 pluto keying daemon. Currently only
191 a limited subset of functions are available with IKEv2
192 (Default AES encryption, authentication based on locally
193 imported X.509 certificates, unencrypted private RSA keys
194 in PKCS#1 file format, limited functionality of the ipsec
201 - the dynamic iptables rules from the _updown_x509 template
202 for KLIPS and the _updown_policy template for NETKEY have
203 been merged into the default _updown script. The existing
204 left|rightfirewall keyword causes the automatic insertion
205 and deletion of ACCEPT rules for tunneled traffic upon
206 the successful setup and teardown of an IPsec SA, respectively.
207 left|rightfirwall can be used with KLIPS under any Linux 2.4
208 kernel or with NETKEY under a Linux kernel version >= 2.6.16
209 in conjuction with iptables >= 1.3.5. For NETKEY under a Linux
210 kernel version < 2.6.16 which does not support IPsec policy
211 matching yet, please continue to use a copy of the _updown_espmark
212 template loaded via the left|rightupdown keyword.
214 - a new left|righthostaccess keyword has been introduced which
215 can be used in conjunction with left|rightfirewall and the
216 default _updown script. By default leftfirewall=yes inserts
217 a bi-directional iptables FORWARD rule for a local client network
218 with a netmask different from 255.255.255.255 (single host).
219 This does not allow to access the VPN gateway host via its
220 internal network interface which is part of the client subnet
221 because an iptables INPUT and OUTPUT rule would be required.
222 lefthostaccess=yes will cause this additional ACCEPT rules to
225 - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal
226 payload is preparsed in order to find out whether the roadwarrior
227 requests PSK or RSA so that a matching connection candidate can
234 - the new _updown_policy template allows ipsec policy based
235 iptables firewall rules. Required are iptables version
236 >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes
237 the _updown_espmark template, so that no INPUT mangle rules
238 are required any more.
240 - added support of DPD restart mode
242 - ipsec starter now allows the use of wildcards in include
243 statements as e.g. in "include /etc/my_ipsec/*.conf".
244 Patch courtesy of Matthias Haas.
246 - the Netscape OID 'employeeNumber' is now recognized and can be
247 used as a Relative Distinguished Name in certificates.
253 - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec
254 command and not of ipsec setup any more.
256 - ipsec starter now supports AH authentication in conjunction with
257 ESP encryption. AH authentication is configured in ipsec.conf
258 via the auth=ah parameter.
260 - The command ipsec scencrypt|scdecrypt <args> is now an alias for
261 ipsec whack --scencrypt|scdecrypt <args>.
263 - get_sa_info() now determines for the native netkey IPsec stack
264 the exact time of the last use of an active eroute. This information
265 is used by the Dead Peer Detection algorithm and is also displayed by
266 the ipsec status command.
272 - running under the native Linux 2.6 IPsec stack, the function
273 get_sa_info() is called by ipsec auto --status to display the current
274 number of transmitted bytes per IPsec SA.
276 - get_sa_info() is also used by the Dead Peer Detection process to detect
277 recent ESP activity. If ESP traffic was received from the peer within
278 the last dpd_delay interval then no R_Y_THERE notification must be sent.
280 - strongSwan now supports the Relative Distinguished Name "unstructuredName"
281 in ID_DER_ASN1_DN identities. The following notations are possible:
283 rightid="unstructuredName=John Doe"
284 rightid="UN=John Doe"
286 - fixed a long-standing bug which caused PSK-based roadwarrior connections
287 to segfault in the function id.c:same_id() called by keys.c:get_secret()
288 if an FQDN, USER_FQDN, or Key ID was defined, as in the following example.
295 - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall).
297 - ipsec starter didn't set host_addr and client.addr ports in whack msg.
299 - in order to guarantee backwards-compatibility with the script-based
300 auto function (e.g. auto --replace), the ipsec starter scripts stores
301 the defaultroute information in the temporary file /var/run/ipsec.info.
303 - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH
304 Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config
307 - the ipsec starter now also recognizes the parameters authby=never and
308 type=passthrough|pass|drop|reject.
314 - ipsec starter now supports the also parameter which allows
315 a modular structure of the connection definitions. Thus
316 "ipsec start" is now ready to replace "ipsec setup".
322 - Mathieu Lafon's popular ipsec starter tool has been added to the
323 strongSwan distribution. Many thanks go to Stephan Scholz from astaro
324 for his integration work. ipsec starter is a C program which is going
325 to replace the various shell and awk starter scripts (setup, _plutoload,
326 _plutostart, _realsetup, _startklips, _confread, and auto). Since
327 ipsec.conf is now parsed only once, the starting of multiple tunnels is
328 accelerated tremedously.
330 - Added support of %defaultroute to the ipsec starter. If the IP address
331 changes, a HUP signal to the ipsec starter will automatically
332 reload pluto's connections.
334 - moved most compile time configurations from pluto/Makefile to
335 Makefile.inc by defining the options USE_LIBCURL, USE_LDAP,
336 USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE.
338 - removed the ipsec verify and ipsec newhostkey commands
340 - fixed some 64-bit issues in formatted print statements
342 - The scepclient functionality implementing the Simple Certificate
343 Enrollment Protocol (SCEP) is nearly complete but hasn't been
350 - CA certicates are now automatically loaded from a smartcard
351 or USB crypto token and appear in the ipsec auto --listcacerts
358 - when using "ipsec whack --scencrypt <data>" with a PKCS#11
359 library that does not support the C_Encrypt() Cryptoki
360 function (e.g. OpenSC), the RSA encryption is done in
361 software using the public key fetched from the smartcard.
363 - The scepclient function now allows to define the
364 validity of a self-signed certificate using the --days,
365 --startdate, and --enddate options. The default validity
366 has been changed from one year to five years.
372 - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11
373 interface to other applications for RSA encryption and decryption
374 via the whack interface. Notation:
376 ipsec whack --scencrypt <data>
377 [--inbase 16|hex|64|base64|256|text|ascii]
378 [--outbase 16|hex|64|base64|256|text|ascii]
381 ipsec whack --scdecrypt <data>
382 [--inbase 16|hex|64|base64|256|text|ascii]
383 [--outbase 16|hex|64|base64|256|text|ascii]
386 The default setting for inbase and outbase is hex.
388 The new proxy interface can be used for securing symmetric
389 encryption keys required by the cryptoloop or dm-crypt
390 disk encryption schemes, especially in the case when
391 pkcs11keepstate=yes causes pluto to lock the pkcs11 slot
394 - if the file /etc/ipsec.secrets is lacking during the startup of
395 pluto then the root-readable file /etc/ipsec.d/private/myKey.der
396 containing a 2048 bit RSA private key and a matching self-signed
397 certificate stored in the file /etc/ipsec.d/certs/selfCert.der
398 is automatically generated by calling the function
400 ipsec scepclient --out pkcs1 --out cert-self
402 scepclient was written by Jan Hutter and Martin Willi, students
403 at the University of Applied Sciences in Rapperswil, Switzerland.
409 - the current extension of the PKCS#7 framework introduced
410 a parsing error in PKCS#7 wrapped X.509 certificates that are
411 e.g. transmitted by Windows XP when multi-level CAs are used.
412 the parsing syntax has been fixed.
414 - added a patch by Gerald Richter which tolerates multiple occurrences
415 of the ipsec0 interface when using KLIPS.
421 - with gawk-3.1.4 the word "default2 has become a protected
422 keyword for use in switch statements and cannot be used any
423 more in the strongSwan scripts. This problem has been
424 solved by renaming "default" to "defaults" and "setdefault"
425 in the scripts _confread and auto, respectively.
427 - introduced the parameter leftsendcert with the values
429 always|yes (the default, always send a cert)
430 ifasked (send the cert only upon a cert request)
431 never|no (never send a cert, used for raw RSA keys and
434 - fixed the initialization of the ESP key length to a default of
435 128 bits in the case that the peer does not send a key length
436 attribute for AES encryption.
438 - applied Herbert Xu's uniqueIDs patch
440 - applied Herbert Xu's CLOEXEC patches
446 - CRLs can now be cached also in the case when the issuer's
447 certificate does not contain a subjectKeyIdentifier field.
448 In that case the subjectKeyIdentifier is computed by pluto as the
449 160 bit SHA-1 hash of the issuer's public key in compliance
450 with section 4.2.1.2 of RFC 3280.
452 - Fixed a bug introduced by strongswan-2.5.1 which eliminated
453 not only multiple Quick Modes of a given connection but also
454 multiple connections between two security gateways.
460 - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute
461 installed either by setting auto=route in ipsec.conf or by
462 a connection put into hold, generates an XFRM_AQUIRE event
463 for each packet that wants to use the not-yet exisiting
464 tunnel. Up to now each XFRM_AQUIRE event led to an entry in
465 the Quick Mode queue, causing multiple IPsec SA to be
466 established in rapid succession. Starting with strongswan-2.5.1
467 only a single IPsec SA is established per host-pair connection.
469 - Right after loading the PKCS#11 module, all smartcard slots are
470 searched for certificates. The result can be viewed using
473 ipsec auto --listcards
475 The certificate objects found in the slots are numbered
476 starting with #1, #2, etc. This position number can be used to address
477 certificates (leftcert=%smartcard) and keys (: PIN %smartcard)
478 in ipsec.conf and ipsec.secrets, respectively:
480 %smartcard (selects object #1)
481 %smartcard#1 (selects object #1)
482 %smartcard#3 (selects object #3)
484 As an alternative the existing retrieval scheme can be used:
486 %smartcard:45 (selects object with id=45)
487 %smartcard0 (selects first object in slot 0)
488 %smartcard4:45 (selects object in slot 4 with id=45)
490 - Depending on the settings of CKA_SIGN and CKA_DECRYPT
491 private key flags either C_Sign() or C_Decrypt() is used
492 to generate a signature.
494 - The output buffer length parameter siglen in C_Sign()
495 is now initialized to the actual size of the output
496 buffer prior to the function call. This fixes the
497 CKR_BUFFER_TOO_SMALL error that could occur when using
498 the OpenSC PKCS#11 module.
500 - Changed the initialization of the PKCS#11 CK_MECHANISM in
501 C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }.
503 - Refactored the RSA public/private key code and transferred it
504 from keys.c to the new pkcs1.c file as a preparatory step
505 towards the release of the SCEP client.
511 - The loading of a PKCS#11 smartcard library module during
512 runtime does not require OpenSC library functions any more
513 because the corresponding code has been integrated into
514 smartcard.c. Also the RSAREF pkcs11 header files have been
515 included in a newly created pluto/rsaref directory so that
516 no external include path has to be defined any longer.
518 - A long-awaited feature has been implemented at last:
519 The local caching of CRLs fetched via HTTP or LDAP, activated
520 by the parameter cachecrls=yes in the config setup section
521 of ipsec.conf. The dynamically fetched CRLs are stored under
522 a unique file name containing the issuer's subjectKeyID
523 in /etc/ipsec.d/crls.
525 - Applied a one-line patch courtesy of Michael Richardson
526 from the Openswan project which fixes the kernel-oops
527 in KLIPS when an snmp daemon is running on the same box.
533 - Eliminated null length CRL distribution point strings.
535 - Fixed a trust path evaluation bug introduced with 2.4.3
541 - Improved the joint OCSP / CRL revocation policy.
542 OCSP responses have precedence over CRL entries.
544 - Introduced support of CRLv2 reason codes.
546 - Fixed a bug with key-pad equipped readers which caused
547 pluto to prompt for the pin via the console when the first
548 occasion to enter the pin via the key-pad was missed.
550 - When pluto is built with LDAP_V3 enabled, the library
551 liblber required by newer versions of openldap is now
558 - Added the _updown_espmark template which requires all
559 incoming ESP traffic to be marked with a default mark
562 - Introduced the pkcs11keepstate parameter in the config setup
563 section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11
564 session and login states are kept as long as possible during
565 the lifetime of pluto. This means that a PIN entry via a key
566 pad has to be done only once.
568 - Introduced the pkcs11module parameter in the config setup
569 section of ipsec.conf which specifies the PKCS#11 module
570 to be used with smart cards. Example:
572 pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo
574 - Added support of smartcard readers equipped with a PIN pad.
576 - Added patch by Jay Pfeifer which detects when netkey
577 modules have been statically built into the Linux 2.6 kernel.
579 - Added two patches by Herbert Xu. The first uses ip xfrm
580 instead of setkey to flush the IPsec policy database. The
581 second sets the optional flag in inbound IPComp SAs only.
583 - Applied Ulrich Weber's patch which fixes an interoperability
584 problem between native IPsec and KLIPS systems caused by
585 setting the replay window to 32 instead of 0 for ipcomp.
591 - Fixed a bug which caused an unwanted Mode Config request
592 to be initiated in the case where "right" was used to denote
593 the local side in ipsec.conf and "left" the remote side,
594 contrary to the recommendation that "right" be remote and
601 - updated Vendor ID to strongSwan-2.4.0
603 - updated copyright statement to include David Buechi and
610 - strongSwan now communicates with attached smartcards and
611 USB crypto tokens via the standardized PKCS #11 interface.
612 By default the OpenSC library from www.opensc.org is used
613 but any other PKCS#11 library could be dynamically linked.
614 strongSwan's PKCS#11 API was implemented by David Buechi
615 and Michael Meier, both graduates of the Zurich University
616 of Applied Sciences in Winterthur, Switzerland.
618 - When a %trap eroute is triggered by an outgoing IP packet
619 then the native IPsec stack of the Linux 2.6 kernel [often/
620 always?] returns an XFRM_ACQUIRE message with an undefined
621 protocol family field and the connection setup fails.
622 As a workaround IPv4 (AF_INET) is now assumed.
624 - the results of the UML test scenarios are now enhanced
625 with block diagrams of the virtual network topology used
626 in a particular test.
632 - fixed IV used to decrypt informational messages.
633 This bug was introduced with Mode Config functionality.
635 - fixed NCP Vendor ID.
637 - undid one of Ulrich Weber's maximum udp size patches
638 because it caused a segmentation fault with NAT-ed
641 - added UML scenarios wildcards and attr-cert which
642 demonstrate the implementation of IPsec policies based
643 on wildcard parameters contained in Distinguished Names and
644 on X.509 attribute certificates, respectively.
650 - Added basic Mode Config functionality
652 - Added Mathieu Lafon's patch which upgrades the status of
653 the NAT-Traversal implementation to RFC 3947.
655 - The _startklips script now also loads the xfrm4_tunnel
658 - Added Ulrich Weber's netlink replay window size and
659 maximum udp size patches.
661 - UML testing now uses the Linux 2.6.10 UML kernel by default.
667 - Eric Marchionni and Patrik Rayo, both recent graduates from
668 the Zuercher Hochschule Winterthur in Switzerland, created a
669 User-Mode-Linux test setup for strongSwan. For more details
670 please read the INSTALL and README documents in the testing
673 - Full support of group attributes based on X.509 attribute
674 certificates. Attribute certificates can be generated
675 using the openac facility. For more details see
679 The group attributes can be used in connection definitions
680 in order to give IPsec access to specific user groups.
681 This is done with the new parameter left|rightgroups as in
683 rightgroups="Research, Sales"
685 giving access to users possessing the group attributes
686 Research or Sales, only.
688 - In Quick Mode clients with subnet mask /32 are now
689 coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should
690 fix rekeying problems with the SafeNet/SoftRemote and NCP
691 Secure Entry Clients.
693 - Changed the defaults of the ikelifetime and keylife parameters
694 to 3h and 1h, respectively. The maximum allowable values are
695 now both set to 24 h.
697 - Suppressed notification wars between two IPsec peers that
698 could e.g. be triggered by incorrect ISAKMP encryption.
700 - Public RSA keys can now have identical IDs if either the
701 issuing CA or the serial number is different. The serial
702 number of a certificate is now shown by the command
704 ipsec auto --listpubkeys
710 - Added Tuomo Soini's sourceip feature which allows a strongSwan
711 roadwarrior to use a fixed Virtual IP (see README section 2.6)
712 and reduces the well-known four tunnel case on VPN gateways to
713 a single tunnel definition (see README section 2.4).
715 - Fixed a bug occuring with NAT-Traversal enabled when the responder
716 suddenly turns initiator and the initiator cannot find a matching
717 connection because of the floated IKE port 4500.
719 - Removed misleading ipsec verify command from barf.
721 - Running under the native IP stack, ipsec --version now shows
722 the Linux kernel version (courtesy to the Openswan project).
728 - Introduced the ipsec auto --listalgs monitoring command which lists
729 all currently registered IKE and ESP algorithms.
731 - Fixed a bug in the ESP algorithm selection occuring when the strict flag
732 is set and the first proposed transform does not match.
734 - Fixed another deadlock in the use of the lock_certs_and_keys() mutex,
735 occuring when a smartcard is present.
737 - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event.
739 - Fixed the printing of the notification names (null)
741 - Applied another of Herbert Xu's Netlink patches.
747 - Support of Dead Peer Detection. The connection parameter
751 activates DPD for the given connection.
753 - The default Opportunistic Encryption (OE) policy groups are not
754 automatically included anymore. Those wishing to activate OE can include
755 the policy group with the following statement in ipsec.conf:
757 include /etc/ipsec.d/examples/oe.conf
759 The default for [right|left]rsasigkey is now set to %cert.
761 - strongSwan now has a Vendor ID of its own which can be activated
762 using the compile option VENDORID
764 - Applied Herbert Xu's patch which sets the compression algorithm correctly.
766 - Applied Herbert Xu's patch fixing an ESPINUDP problem
768 - Applied Herbert Xu's patch setting source/destination port numbers.
770 - Reapplied one of Herbert Xu's NAT-Traversal patches which got
771 lost during the migration from SuperFreeS/WAN.
773 - Fixed a deadlock in the use of the lock_certs_and_keys() mutex.
775 - Fixed the unsharing of alg parameters when instantiating group
782 - Thomas Walpuski made me aware of a potential DoS attack via
783 a PKCS#7-wrapped certificate bundle which could overwrite valid CA
784 certificates in Pluto's authority certificate store. This vulnerability
785 was fixed by establishing trust in CA candidate certificates up to a
786 trusted root CA prior to insertion into Pluto's chained list.
788 - replaced the --assign option by the -v option in the auto awk script
789 in order to make it run with mawk under debian/woody.
795 - Split of the status information between ipsec auto --status (concise)
796 and ipsec auto --statusall (verbose). Both commands can be used with
797 an optional connection selector:
799 ipsec auto --status[all] <connection_name>
801 - Added the description of X.509 related features to the ipsec_auto(8)
804 - Hardened the ASN.1 parser in debug mode, especially the printing
805 of malformed distinguished names.
807 - The size of an RSA public key received in a certificate is now restricted to
809 512 bits <= modulus length <= 8192 bits.
811 - Fixed the debug mode enumeration.
817 - Fixed another PKCS#7 vulnerability which could lead to an
818 endless loop while following the X.509 trust chain.
824 - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski
825 that accepted end certificates having identical issuer and subject
826 distinguished names in a multi-tier X.509 trust chain.
832 - Removed all remaining references to ipsec_netlink.h in KLIPS.
838 - The new "ca" section allows to define the following parameters:
841 cacert=koolCA.pem # cacert of kool CA
842 ocspuri=http://ocsp.kool.net:8001 # ocsp server
843 ldapserver=ldap.kool.net # default ldap server
844 crluri=http://www.kool.net/kool.crl # crl distribution point
845 crluri2="ldap:///O=Kool, C= .." # crl distribution point #2
846 auto=add # add, ignore
848 The ca definitions can be monitored via the command
850 ipsec auto --listcainfos
852 - Fixed cosmetic corruption of /proc filesystem by integrating
853 D. Hugh Redelmeier's freeswan-2.06 kernel fixes.
859 - Added support for the 818043 NAT-Traversal update of Microsoft's
860 Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode.
862 - A symbolic link to libcrypto is now added in the kernel sources
863 during kernel compilation
865 - Fixed a couple of 64 bit issues (mostly casts to int).
866 Thanks to Ken Bantoft who checked my sources on a 64 bit platform.
868 - Replaced s[n]printf() statements in the kernel by ipsec_snprintf().
869 Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro
870 of the FreeS/WAN team who solved this problem with the 2.4.25 kernel.
876 - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName
877 certificate extension which contains no generalName item) can cause
878 a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has
879 been hardened to make it more robust against malformed ASN.1 objects.
881 - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native
882 Linux 2.6 IPsec stack.
888 - based on freeswan-2.04, x509-1.5.3, nat-0.6c, alg-0.8.1rc12
