4 - Server side cookie support. If to may IKE_SAs are in CONNECTING state,
5 cookies are enabled and protect against DoS attacks with faked source
6 addresses. Number of IKE_SAs in CONNECTING state is also limited per
7 peer address to avoid resource exhaustion. IKE_SA_INIT messages are
8 compared to properly detect retransmissions and incoming retransmits are
9 detected even if the IKE_SA is blocked (e.g. doing OCSP fetches).
14 - Support of SHA2_384 hash function for protecting IKEv1
15 negotiations and support of SHA2 signatures in X.509 certificates.
17 - Fixed a serious bug in the computation of the SHA2-512 HMAC
18 function. Introduced automatic self-test of all IKEv1 hash
19 and hmac functions during pluto startup. Failure of a self-test
20 currently issues a warning only but does not exit pluto [yet].
22 - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2.
24 - Full support of CA information sections. ipsec listcainfos
25 now shows all collected crlDistributionPoints and OCSP
28 - Support of the Online Certificate Status Protocol (OCSP) for IKEv2.
29 This feature requires the HTTP fetching capabilities of the libcurl
30 library which must be enabled by setting the --enable-http configure
33 - Refactored core of the IKEv2 message processing code, allowing better
34 code reuse and separation.
36 - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration
37 payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted
38 by the requestor and installed in a resolv.conf file.
40 - The IKEv2 daemon charon installs a route for each IPsec policy to use
41 the correct source address even if an application does not explicitly
44 - Integrated the EAP framework into charon which loads pluggable EAP library
45 modules. The ipsec.conf parameter authby=eap initiates EAP authentication
46 on the client side, while the "eap" parameter on the server side defines
47 the EAP method to use for client authentication.
48 A generic client side EAP-Identity module and an EAP-SIM authentication
49 module using a third party card reader implementation are included.
51 - Added client side support for cookies.
53 - Integrated the fixes done at the IKEv2 interoperability bakeoff, including
54 strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor
55 fixes to enhance interoperability with other implementations.
60 - strongSwan now interoperates with the NCP Secure Entry Client,
61 the Shrew Soft VPN Client, and the Cisco VPN client, doing both
62 XAUTH and Mode Config.
64 - UNITY attributes are now recognized and UNITY_BANNER is set
71 - IKEv1: Support for extended authentication (XAUTH) in combination
72 with ISAKMP Main Mode RSA or PSK authentication. Both client and
73 server side were implemented. Handling of user credentials can
74 be done by a run-time loadable XAUTH module. By default user
75 credentials are stored in ipsec.secrets.
77 - IKEv2: Support for reauthentication when rekeying
79 - IKEv2: Support for transport mode
81 - fixed a lot of bugs related to byte order
83 - various other bugfixes
89 - IKEv1: Implementation of ModeConfig push mode via the new connection
90 keyword modeconfig=push allows interoperability with Cisco VPN gateways.
92 - IKEv1: The command ipsec statusall now shows "DPD active" for all
93 ISAKMP SAs that are under active Dead Peer Detection control.
95 - IKEv2: Charon's logging and debugging framework has been completely rewritten.
96 Instead of logger, special printf() functions are used to directly
97 print objects like hosts (%H) identifications (%D), certificates (%Q),
98 etc. The number of debugging levels have been reduced to:
100 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private)
102 The debugging levels can either be specified statically in ipsec.conf as
105 charondebug="lib 1, cfg 3, net 2"
107 or changed at runtime via stroke as
109 ipsec stroke loglevel cfg 2
115 - Implemented full support for IPv6-in-IPv6 tunnels.
117 - Added configuration options for dead peer detection in IKEv2. dpd_action
118 types "clear", "hold" and "restart" are supported. The dpd_timeout
119 value is not used, as the normal retransmission policy applies to
120 detect dead peers. The dpd_delay parameter enables sending of empty
121 informational message to detect dead peers in case of inactivity.
123 - Added support for preshared keys in IKEv2. PSK keys configured in
124 ipsec.secrets are loaded. The authby parameter specifies the authentication
125 method to authentificate ourself, the other peer may use PSK or RSA.
127 - Changed retransmission policy to respect the keyingtries parameter.
129 - Added private key decryption. PEM keys encrypted with AES-128/192/256
130 or 3DES are supported.
132 - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to
135 - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates
136 signed with such a hash algorithm.
138 - Added initial support for updown scripts. The actions up-host/client and
139 down-host/client are executed. The leftfirewall=yes parameter
140 uses the default updown script to insert dynamic firewall rules, a custom
141 updown script may be specified with the leftupdown parameter.
147 - Added support for the auto=route ipsec.conf parameter and the
148 ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and
149 CHILD_SAs dynamically on demand when traffic is detected by the
152 - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter.
153 As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only
154 new keys are generated using perfect forward secrecy. An optional flag
155 which enforces reauthentication will be implemented later.
157 - "sha" and "sha1" are now treated as synonyms in the ike= and esp=
158 algorithm configuration statements.
164 - Full X.509 certificate trust chain verification has been implemented.
165 End entity certificates can be exchanged via CERT payloads. The current
166 default is leftsendcert=always, since CERTREQ payloads are not supported
167 yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls.
169 - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2
170 would offer more possibilities for traffic selection, but the Linux kernel
171 currently does not support it. That's why we stick with these simple
172 ipsec.conf rules for now.
174 - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no
175 IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear,
178 - Initial NAT traversal support in IKEv2. Charon includes NAT detection
179 notify payloads to detect NAT routers between the peers. It switches
180 to port 4500, uses UDP encapsulated ESP packets, handles peer address
181 changes gracefully and sends keep alive message periodically.
183 - Reimplemented IKE_SA state machine for charon, which allows simultaneous
184 rekeying, more shared code, cleaner design, proper retransmission
185 and a more extensible code base.
187 - The mixed PSK/RSA roadwarrior detection capability introduced by the
188 strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal
189 payloads by the responder right before any defined IKE Main Mode state had
190 been established. Although any form of bad proposal syntax was being correctly
191 detected by the payload parser, the subsequent error handler didn't check
192 the state pointer before logging current state information, causing an
193 immediate crash of the pluto keying daemon due to a NULL pointer.
199 - Added algorithm selection to charon: New default algorithms for
200 ike=aes128-sha-modp2048, as both daemons support it. The default
201 for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles
202 the ike/esp parameter the same way as pluto. As this syntax does
203 not allow specification of a pseudo random function, the same
204 algorithm as for integrity is used (currently sha/md5). Supported
206 Encryption: aes128, aes192, aes256
207 Integrity/PRF: md5, sha (using hmac)
208 DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192
210 Encryption: aes128, aes192, aes256, 3des, blowfish128,
211 blowfish192, blowfish256
213 More IKE encryption algorithms will come after porting libcrypto into
216 - initial support for rekeying CHILD_SAs using IKEv2. Currently no
217 perfect forward secrecy is used. The rekeying parameters rekey,
218 rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported
219 when using IKEv2. WARNING: charon currently is unable to handle
220 simultaneous rekeying. To avoid such a situation, use a large
221 rekeyfuzz, or even better, set rekey=no on one peer.
223 - support for host2host, net2net, host2net (roadwarrior) tunnels
224 using predefined RSA certificates (see uml scenarios for
225 configuration examples).
227 - new build environment featuring autotools. Features such
228 as HTTP, LDAP and smartcard support may be enabled using
229 the ./configure script. Changing install directories
230 is possible, too. See ./configure --help for more details.
232 - better integration of charon with ipsec starter, which allows
233 (almost) transparent operation with both daemons. charon
234 handles ipsec commands up, down, status, statusall, listall,
235 listcerts and allows proper load, reload and delete of connections
242 - initial support of the IKEv2 protocol. Connections in
243 ipsec.conf designated by keyexchange=ikev2 are negotiated
244 by the new IKEv2 charon keying daemon whereas those marked
245 by keyexchange=ikev1 or the default keyexchange=ike are
246 handled thy the IKEv1 pluto keying daemon. Currently only
247 a limited subset of functions are available with IKEv2
248 (Default AES encryption, authentication based on locally
249 imported X.509 certificates, unencrypted private RSA keys
250 in PKCS#1 file format, limited functionality of the ipsec
257 - the dynamic iptables rules from the _updown_x509 template
258 for KLIPS and the _updown_policy template for NETKEY have
259 been merged into the default _updown script. The existing
260 left|rightfirewall keyword causes the automatic insertion
261 and deletion of ACCEPT rules for tunneled traffic upon
262 the successful setup and teardown of an IPsec SA, respectively.
263 left|rightfirwall can be used with KLIPS under any Linux 2.4
264 kernel or with NETKEY under a Linux kernel version >= 2.6.16
265 in conjuction with iptables >= 1.3.5. For NETKEY under a Linux
266 kernel version < 2.6.16 which does not support IPsec policy
267 matching yet, please continue to use a copy of the _updown_espmark
268 template loaded via the left|rightupdown keyword.
270 - a new left|righthostaccess keyword has been introduced which
271 can be used in conjunction with left|rightfirewall and the
272 default _updown script. By default leftfirewall=yes inserts
273 a bi-directional iptables FORWARD rule for a local client network
274 with a netmask different from 255.255.255.255 (single host).
275 This does not allow to access the VPN gateway host via its
276 internal network interface which is part of the client subnet
277 because an iptables INPUT and OUTPUT rule would be required.
278 lefthostaccess=yes will cause this additional ACCEPT rules to
281 - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal
282 payload is preparsed in order to find out whether the roadwarrior
283 requests PSK or RSA so that a matching connection candidate can
290 - the new _updown_policy template allows ipsec policy based
291 iptables firewall rules. Required are iptables version
292 >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes
293 the _updown_espmark template, so that no INPUT mangle rules
294 are required any more.
296 - added support of DPD restart mode
298 - ipsec starter now allows the use of wildcards in include
299 statements as e.g. in "include /etc/my_ipsec/*.conf".
300 Patch courtesy of Matthias Haas.
302 - the Netscape OID 'employeeNumber' is now recognized and can be
303 used as a Relative Distinguished Name in certificates.
309 - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec
310 command and not of ipsec setup any more.
312 - ipsec starter now supports AH authentication in conjunction with
313 ESP encryption. AH authentication is configured in ipsec.conf
314 via the auth=ah parameter.
316 - The command ipsec scencrypt|scdecrypt <args> is now an alias for
317 ipsec whack --scencrypt|scdecrypt <args>.
319 - get_sa_info() now determines for the native netkey IPsec stack
320 the exact time of the last use of an active eroute. This information
321 is used by the Dead Peer Detection algorithm and is also displayed by
322 the ipsec status command.
328 - running under the native Linux 2.6 IPsec stack, the function
329 get_sa_info() is called by ipsec auto --status to display the current
330 number of transmitted bytes per IPsec SA.
332 - get_sa_info() is also used by the Dead Peer Detection process to detect
333 recent ESP activity. If ESP traffic was received from the peer within
334 the last dpd_delay interval then no R_Y_THERE notification must be sent.
336 - strongSwan now supports the Relative Distinguished Name "unstructuredName"
337 in ID_DER_ASN1_DN identities. The following notations are possible:
339 rightid="unstructuredName=John Doe"
340 rightid="UN=John Doe"
342 - fixed a long-standing bug which caused PSK-based roadwarrior connections
343 to segfault in the function id.c:same_id() called by keys.c:get_secret()
344 if an FQDN, USER_FQDN, or Key ID was defined, as in the following example.
351 - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall).
353 - ipsec starter didn't set host_addr and client.addr ports in whack msg.
355 - in order to guarantee backwards-compatibility with the script-based
356 auto function (e.g. auto --replace), the ipsec starter scripts stores
357 the defaultroute information in the temporary file /var/run/ipsec.info.
359 - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH
360 Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config
363 - the ipsec starter now also recognizes the parameters authby=never and
364 type=passthrough|pass|drop|reject.
370 - ipsec starter now supports the also parameter which allows
371 a modular structure of the connection definitions. Thus
372 "ipsec start" is now ready to replace "ipsec setup".
378 - Mathieu Lafon's popular ipsec starter tool has been added to the
379 strongSwan distribution. Many thanks go to Stephan Scholz from astaro
380 for his integration work. ipsec starter is a C program which is going
381 to replace the various shell and awk starter scripts (setup, _plutoload,
382 _plutostart, _realsetup, _startklips, _confread, and auto). Since
383 ipsec.conf is now parsed only once, the starting of multiple tunnels is
384 accelerated tremedously.
386 - Added support of %defaultroute to the ipsec starter. If the IP address
387 changes, a HUP signal to the ipsec starter will automatically
388 reload pluto's connections.
390 - moved most compile time configurations from pluto/Makefile to
391 Makefile.inc by defining the options USE_LIBCURL, USE_LDAP,
392 USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE.
394 - removed the ipsec verify and ipsec newhostkey commands
396 - fixed some 64-bit issues in formatted print statements
398 - The scepclient functionality implementing the Simple Certificate
399 Enrollment Protocol (SCEP) is nearly complete but hasn't been
406 - CA certicates are now automatically loaded from a smartcard
407 or USB crypto token and appear in the ipsec auto --listcacerts
414 - when using "ipsec whack --scencrypt <data>" with a PKCS#11
415 library that does not support the C_Encrypt() Cryptoki
416 function (e.g. OpenSC), the RSA encryption is done in
417 software using the public key fetched from the smartcard.
419 - The scepclient function now allows to define the
420 validity of a self-signed certificate using the --days,
421 --startdate, and --enddate options. The default validity
422 has been changed from one year to five years.
428 - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11
429 interface to other applications for RSA encryption and decryption
430 via the whack interface. Notation:
432 ipsec whack --scencrypt <data>
433 [--inbase 16|hex|64|base64|256|text|ascii]
434 [--outbase 16|hex|64|base64|256|text|ascii]
437 ipsec whack --scdecrypt <data>
438 [--inbase 16|hex|64|base64|256|text|ascii]
439 [--outbase 16|hex|64|base64|256|text|ascii]
442 The default setting for inbase and outbase is hex.
444 The new proxy interface can be used for securing symmetric
445 encryption keys required by the cryptoloop or dm-crypt
446 disk encryption schemes, especially in the case when
447 pkcs11keepstate=yes causes pluto to lock the pkcs11 slot
450 - if the file /etc/ipsec.secrets is lacking during the startup of
451 pluto then the root-readable file /etc/ipsec.d/private/myKey.der
452 containing a 2048 bit RSA private key and a matching self-signed
453 certificate stored in the file /etc/ipsec.d/certs/selfCert.der
454 is automatically generated by calling the function
456 ipsec scepclient --out pkcs1 --out cert-self
458 scepclient was written by Jan Hutter and Martin Willi, students
459 at the University of Applied Sciences in Rapperswil, Switzerland.
465 - the current extension of the PKCS#7 framework introduced
466 a parsing error in PKCS#7 wrapped X.509 certificates that are
467 e.g. transmitted by Windows XP when multi-level CAs are used.
468 the parsing syntax has been fixed.
470 - added a patch by Gerald Richter which tolerates multiple occurrences
471 of the ipsec0 interface when using KLIPS.
477 - with gawk-3.1.4 the word "default2 has become a protected
478 keyword for use in switch statements and cannot be used any
479 more in the strongSwan scripts. This problem has been
480 solved by renaming "default" to "defaults" and "setdefault"
481 in the scripts _confread and auto, respectively.
483 - introduced the parameter leftsendcert with the values
485 always|yes (the default, always send a cert)
486 ifasked (send the cert only upon a cert request)
487 never|no (never send a cert, used for raw RSA keys and
490 - fixed the initialization of the ESP key length to a default of
491 128 bits in the case that the peer does not send a key length
492 attribute for AES encryption.
494 - applied Herbert Xu's uniqueIDs patch
496 - applied Herbert Xu's CLOEXEC patches
502 - CRLs can now be cached also in the case when the issuer's
503 certificate does not contain a subjectKeyIdentifier field.
504 In that case the subjectKeyIdentifier is computed by pluto as the
505 160 bit SHA-1 hash of the issuer's public key in compliance
506 with section 4.2.1.2 of RFC 3280.
508 - Fixed a bug introduced by strongswan-2.5.1 which eliminated
509 not only multiple Quick Modes of a given connection but also
510 multiple connections between two security gateways.
516 - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute
517 installed either by setting auto=route in ipsec.conf or by
518 a connection put into hold, generates an XFRM_AQUIRE event
519 for each packet that wants to use the not-yet exisiting
520 tunnel. Up to now each XFRM_AQUIRE event led to an entry in
521 the Quick Mode queue, causing multiple IPsec SA to be
522 established in rapid succession. Starting with strongswan-2.5.1
523 only a single IPsec SA is established per host-pair connection.
525 - Right after loading the PKCS#11 module, all smartcard slots are
526 searched for certificates. The result can be viewed using
529 ipsec auto --listcards
531 The certificate objects found in the slots are numbered
532 starting with #1, #2, etc. This position number can be used to address
533 certificates (leftcert=%smartcard) and keys (: PIN %smartcard)
534 in ipsec.conf and ipsec.secrets, respectively:
536 %smartcard (selects object #1)
537 %smartcard#1 (selects object #1)
538 %smartcard#3 (selects object #3)
540 As an alternative the existing retrieval scheme can be used:
542 %smartcard:45 (selects object with id=45)
543 %smartcard0 (selects first object in slot 0)
544 %smartcard4:45 (selects object in slot 4 with id=45)
546 - Depending on the settings of CKA_SIGN and CKA_DECRYPT
547 private key flags either C_Sign() or C_Decrypt() is used
548 to generate a signature.
550 - The output buffer length parameter siglen in C_Sign()
551 is now initialized to the actual size of the output
552 buffer prior to the function call. This fixes the
553 CKR_BUFFER_TOO_SMALL error that could occur when using
554 the OpenSC PKCS#11 module.
556 - Changed the initialization of the PKCS#11 CK_MECHANISM in
557 C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }.
559 - Refactored the RSA public/private key code and transferred it
560 from keys.c to the new pkcs1.c file as a preparatory step
561 towards the release of the SCEP client.
567 - The loading of a PKCS#11 smartcard library module during
568 runtime does not require OpenSC library functions any more
569 because the corresponding code has been integrated into
570 smartcard.c. Also the RSAREF pkcs11 header files have been
571 included in a newly created pluto/rsaref directory so that
572 no external include path has to be defined any longer.
574 - A long-awaited feature has been implemented at last:
575 The local caching of CRLs fetched via HTTP or LDAP, activated
576 by the parameter cachecrls=yes in the config setup section
577 of ipsec.conf. The dynamically fetched CRLs are stored under
578 a unique file name containing the issuer's subjectKeyID
579 in /etc/ipsec.d/crls.
581 - Applied a one-line patch courtesy of Michael Richardson
582 from the Openswan project which fixes the kernel-oops
583 in KLIPS when an snmp daemon is running on the same box.
589 - Eliminated null length CRL distribution point strings.
591 - Fixed a trust path evaluation bug introduced with 2.4.3
597 - Improved the joint OCSP / CRL revocation policy.
598 OCSP responses have precedence over CRL entries.
600 - Introduced support of CRLv2 reason codes.
602 - Fixed a bug with key-pad equipped readers which caused
603 pluto to prompt for the pin via the console when the first
604 occasion to enter the pin via the key-pad was missed.
606 - When pluto is built with LDAP_V3 enabled, the library
607 liblber required by newer versions of openldap is now
614 - Added the _updown_espmark template which requires all
615 incoming ESP traffic to be marked with a default mark
618 - Introduced the pkcs11keepstate parameter in the config setup
619 section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11
620 session and login states are kept as long as possible during
621 the lifetime of pluto. This means that a PIN entry via a key
622 pad has to be done only once.
624 - Introduced the pkcs11module parameter in the config setup
625 section of ipsec.conf which specifies the PKCS#11 module
626 to be used with smart cards. Example:
628 pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo
630 - Added support of smartcard readers equipped with a PIN pad.
632 - Added patch by Jay Pfeifer which detects when netkey
633 modules have been statically built into the Linux 2.6 kernel.
635 - Added two patches by Herbert Xu. The first uses ip xfrm
636 instead of setkey to flush the IPsec policy database. The
637 second sets the optional flag in inbound IPComp SAs only.
639 - Applied Ulrich Weber's patch which fixes an interoperability
640 problem between native IPsec and KLIPS systems caused by
641 setting the replay window to 32 instead of 0 for ipcomp.
647 - Fixed a bug which caused an unwanted Mode Config request
648 to be initiated in the case where "right" was used to denote
649 the local side in ipsec.conf and "left" the remote side,
650 contrary to the recommendation that "right" be remote and
657 - updated Vendor ID to strongSwan-2.4.0
659 - updated copyright statement to include David Buechi and
666 - strongSwan now communicates with attached smartcards and
667 USB crypto tokens via the standardized PKCS #11 interface.
668 By default the OpenSC library from www.opensc.org is used
669 but any other PKCS#11 library could be dynamically linked.
670 strongSwan's PKCS#11 API was implemented by David Buechi
671 and Michael Meier, both graduates of the Zurich University
672 of Applied Sciences in Winterthur, Switzerland.
674 - When a %trap eroute is triggered by an outgoing IP packet
675 then the native IPsec stack of the Linux 2.6 kernel [often/
676 always?] returns an XFRM_ACQUIRE message with an undefined
677 protocol family field and the connection setup fails.
678 As a workaround IPv4 (AF_INET) is now assumed.
680 - the results of the UML test scenarios are now enhanced
681 with block diagrams of the virtual network topology used
682 in a particular test.
688 - fixed IV used to decrypt informational messages.
689 This bug was introduced with Mode Config functionality.
691 - fixed NCP Vendor ID.
693 - undid one of Ulrich Weber's maximum udp size patches
694 because it caused a segmentation fault with NAT-ed
697 - added UML scenarios wildcards and attr-cert which
698 demonstrate the implementation of IPsec policies based
699 on wildcard parameters contained in Distinguished Names and
700 on X.509 attribute certificates, respectively.
706 - Added basic Mode Config functionality
708 - Added Mathieu Lafon's patch which upgrades the status of
709 the NAT-Traversal implementation to RFC 3947.
711 - The _startklips script now also loads the xfrm4_tunnel
714 - Added Ulrich Weber's netlink replay window size and
715 maximum udp size patches.
717 - UML testing now uses the Linux 2.6.10 UML kernel by default.
723 - Eric Marchionni and Patrik Rayo, both recent graduates from
724 the Zuercher Hochschule Winterthur in Switzerland, created a
725 User-Mode-Linux test setup for strongSwan. For more details
726 please read the INSTALL and README documents in the testing
729 - Full support of group attributes based on X.509 attribute
730 certificates. Attribute certificates can be generated
731 using the openac facility. For more details see
735 The group attributes can be used in connection definitions
736 in order to give IPsec access to specific user groups.
737 This is done with the new parameter left|rightgroups as in
739 rightgroups="Research, Sales"
741 giving access to users possessing the group attributes
742 Research or Sales, only.
744 - In Quick Mode clients with subnet mask /32 are now
745 coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should
746 fix rekeying problems with the SafeNet/SoftRemote and NCP
747 Secure Entry Clients.
749 - Changed the defaults of the ikelifetime and keylife parameters
750 to 3h and 1h, respectively. The maximum allowable values are
751 now both set to 24 h.
753 - Suppressed notification wars between two IPsec peers that
754 could e.g. be triggered by incorrect ISAKMP encryption.
756 - Public RSA keys can now have identical IDs if either the
757 issuing CA or the serial number is different. The serial
758 number of a certificate is now shown by the command
760 ipsec auto --listpubkeys
766 - Added Tuomo Soini's sourceip feature which allows a strongSwan
767 roadwarrior to use a fixed Virtual IP (see README section 2.6)
768 and reduces the well-known four tunnel case on VPN gateways to
769 a single tunnel definition (see README section 2.4).
771 - Fixed a bug occuring with NAT-Traversal enabled when the responder
772 suddenly turns initiator and the initiator cannot find a matching
773 connection because of the floated IKE port 4500.
775 - Removed misleading ipsec verify command from barf.
777 - Running under the native IP stack, ipsec --version now shows
778 the Linux kernel version (courtesy to the Openswan project).
784 - Introduced the ipsec auto --listalgs monitoring command which lists
785 all currently registered IKE and ESP algorithms.
787 - Fixed a bug in the ESP algorithm selection occuring when the strict flag
788 is set and the first proposed transform does not match.
790 - Fixed another deadlock in the use of the lock_certs_and_keys() mutex,
791 occuring when a smartcard is present.
793 - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event.
795 - Fixed the printing of the notification names (null)
797 - Applied another of Herbert Xu's Netlink patches.
803 - Support of Dead Peer Detection. The connection parameter
807 activates DPD for the given connection.
809 - The default Opportunistic Encryption (OE) policy groups are not
810 automatically included anymore. Those wishing to activate OE can include
811 the policy group with the following statement in ipsec.conf:
813 include /etc/ipsec.d/examples/oe.conf
815 The default for [right|left]rsasigkey is now set to %cert.
817 - strongSwan now has a Vendor ID of its own which can be activated
818 using the compile option VENDORID
820 - Applied Herbert Xu's patch which sets the compression algorithm correctly.
822 - Applied Herbert Xu's patch fixing an ESPINUDP problem
824 - Applied Herbert Xu's patch setting source/destination port numbers.
826 - Reapplied one of Herbert Xu's NAT-Traversal patches which got
827 lost during the migration from SuperFreeS/WAN.
829 - Fixed a deadlock in the use of the lock_certs_and_keys() mutex.
831 - Fixed the unsharing of alg parameters when instantiating group
838 - Thomas Walpuski made me aware of a potential DoS attack via
839 a PKCS#7-wrapped certificate bundle which could overwrite valid CA
840 certificates in Pluto's authority certificate store. This vulnerability
841 was fixed by establishing trust in CA candidate certificates up to a
842 trusted root CA prior to insertion into Pluto's chained list.
844 - replaced the --assign option by the -v option in the auto awk script
845 in order to make it run with mawk under debian/woody.
851 - Split of the status information between ipsec auto --status (concise)
852 and ipsec auto --statusall (verbose). Both commands can be used with
853 an optional connection selector:
855 ipsec auto --status[all] <connection_name>
857 - Added the description of X.509 related features to the ipsec_auto(8)
860 - Hardened the ASN.1 parser in debug mode, especially the printing
861 of malformed distinguished names.
863 - The size of an RSA public key received in a certificate is now restricted to
865 512 bits <= modulus length <= 8192 bits.
867 - Fixed the debug mode enumeration.
873 - Fixed another PKCS#7 vulnerability which could lead to an
874 endless loop while following the X.509 trust chain.
880 - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski
881 that accepted end certificates having identical issuer and subject
882 distinguished names in a multi-tier X.509 trust chain.
888 - Removed all remaining references to ipsec_netlink.h in KLIPS.
894 - The new "ca" section allows to define the following parameters:
897 cacert=koolCA.pem # cacert of kool CA
898 ocspuri=http://ocsp.kool.net:8001 # ocsp server
899 ldapserver=ldap.kool.net # default ldap server
900 crluri=http://www.kool.net/kool.crl # crl distribution point
901 crluri2="ldap:///O=Kool, C= .." # crl distribution point #2
902 auto=add # add, ignore
904 The ca definitions can be monitored via the command
906 ipsec auto --listcainfos
908 - Fixed cosmetic corruption of /proc filesystem by integrating
909 D. Hugh Redelmeier's freeswan-2.06 kernel fixes.
915 - Added support for the 818043 NAT-Traversal update of Microsoft's
916 Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode.
918 - A symbolic link to libcrypto is now added in the kernel sources
919 during kernel compilation
921 - Fixed a couple of 64 bit issues (mostly casts to int).
922 Thanks to Ken Bantoft who checked my sources on a 64 bit platform.
924 - Replaced s[n]printf() statements in the kernel by ipsec_snprintf().
925 Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro
926 of the FreeS/WAN team who solved this problem with the 2.4.25 kernel.
932 - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName
933 certificate extension which contains no generalName item) can cause
934 a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has
935 been hardened to make it more robust against malformed ASN.1 objects.
937 - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native
938 Linux 2.6 IPsec stack.
944 - based on freeswan-2.04, x509-1.5.3, nat-0.6c, alg-0.8.1rc12
