4 - Support for an additional diffie hellman exchange when creating/rekeying
5 a CHILD_SA in IKEv2 (PFS). PFS is enabled when the proposal contains a
6 DH group (e.g. "esp=aes128-sha1-modp1536"). Further, DH group negotiation
7 is implemented properly for rekeying.
9 - Support for the AES-XCBC-96 MAC algorithm for IPsec SAs when using IKEv2
10 (requires linux >= 2.6.20). It is enabled using e.g. "esp=aes256-aesxcbc".
12 - Working IPv4-in-IPv6 and IPv6-in-IPv4 tunnels for linux >= 2.6.21.
14 - Added support for EAP modules which do not establish an MSK.
16 - The xauth_modules.verify_secret() function now passes the
22 - Server side cookie support. If to may IKE_SAs are in CONNECTING state,
23 cookies are enabled and protect against DoS attacks with faked source
24 addresses. Number of IKE_SAs in CONNECTING state is also limited per
25 peer address to avoid resource exhaustion. IKE_SA_INIT messages are
26 compared to properly detect retransmissions and incoming retransmits are
27 detected even if the IKE_SA is blocked (e.g. doing OCSP fetches).
29 - The IKEv2 daemon charon now supports dynamic http- and ldap-based CRL
30 fetching enabled by crlcheckinterval > 0 and caching fetched CRLs
31 enabled by cachecrls=yes.
33 - Added the configuration options --enable-nat-transport which enables
34 the potentially insecure NAT traversal for IPsec transport mode and
35 --disable-vendor-id which disables the sending of the strongSwan
38 - Fixed a long-standing bug in the pluto IKEv1 daemon which caused
39 a segmentation fault if a malformed payload was detected in the
40 IKE MR2 message and pluto tried to send an encrypted notification
43 - Added the NATT_IETF_02_N Vendor ID in order to support IKEv1 connections
44 with Windows 2003 Server which uses a wrong VID hash.
50 - Support of SHA2_384 hash function for protecting IKEv1
51 negotiations and support of SHA2 signatures in X.509 certificates.
53 - Fixed a serious bug in the computation of the SHA2-512 HMAC
54 function. Introduced automatic self-test of all IKEv1 hash
55 and hmac functions during pluto startup. Failure of a self-test
56 currently issues a warning only but does not exit pluto [yet].
58 - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2.
60 - Full support of CA information sections. ipsec listcainfos
61 now shows all collected crlDistributionPoints and OCSP
64 - Support of the Online Certificate Status Protocol (OCSP) for IKEv2.
65 This feature requires the HTTP fetching capabilities of the libcurl
66 library which must be enabled by setting the --enable-http configure
69 - Refactored core of the IKEv2 message processing code, allowing better
70 code reuse and separation.
72 - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration
73 payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted
74 by the requestor and installed in a resolv.conf file.
76 - The IKEv2 daemon charon installs a route for each IPsec policy to use
77 the correct source address even if an application does not explicitly
80 - Integrated the EAP framework into charon which loads pluggable EAP library
81 modules. The ipsec.conf parameter authby=eap initiates EAP authentication
82 on the client side, while the "eap" parameter on the server side defines
83 the EAP method to use for client authentication.
84 A generic client side EAP-Identity module and an EAP-SIM authentication
85 module using a third party card reader implementation are included.
87 - Added client side support for cookies.
89 - Integrated the fixes done at the IKEv2 interoperability bakeoff, including
90 strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor
91 fixes to enhance interoperability with other implementations.
96 - strongSwan now interoperates with the NCP Secure Entry Client,
97 the Shrew Soft VPN Client, and the Cisco VPN client, doing both
98 XAUTH and Mode Config.
100 - UNITY attributes are now recognized and UNITY_BANNER is set
107 - IKEv1: Support for extended authentication (XAUTH) in combination
108 with ISAKMP Main Mode RSA or PSK authentication. Both client and
109 server side were implemented. Handling of user credentials can
110 be done by a run-time loadable XAUTH module. By default user
111 credentials are stored in ipsec.secrets.
113 - IKEv2: Support for reauthentication when rekeying
115 - IKEv2: Support for transport mode
117 - fixed a lot of bugs related to byte order
119 - various other bugfixes
125 - IKEv1: Implementation of ModeConfig push mode via the new connection
126 keyword modeconfig=push allows interoperability with Cisco VPN gateways.
128 - IKEv1: The command ipsec statusall now shows "DPD active" for all
129 ISAKMP SAs that are under active Dead Peer Detection control.
131 - IKEv2: Charon's logging and debugging framework has been completely rewritten.
132 Instead of logger, special printf() functions are used to directly
133 print objects like hosts (%H) identifications (%D), certificates (%Q),
134 etc. The number of debugging levels have been reduced to:
136 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private)
138 The debugging levels can either be specified statically in ipsec.conf as
141 charondebug="lib 1, cfg 3, net 2"
143 or changed at runtime via stroke as
145 ipsec stroke loglevel cfg 2
151 - Implemented full support for IPv6-in-IPv6 tunnels.
153 - Added configuration options for dead peer detection in IKEv2. dpd_action
154 types "clear", "hold" and "restart" are supported. The dpd_timeout
155 value is not used, as the normal retransmission policy applies to
156 detect dead peers. The dpd_delay parameter enables sending of empty
157 informational message to detect dead peers in case of inactivity.
159 - Added support for preshared keys in IKEv2. PSK keys configured in
160 ipsec.secrets are loaded. The authby parameter specifies the authentication
161 method to authentificate ourself, the other peer may use PSK or RSA.
163 - Changed retransmission policy to respect the keyingtries parameter.
165 - Added private key decryption. PEM keys encrypted with AES-128/192/256
166 or 3DES are supported.
168 - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to
171 - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates
172 signed with such a hash algorithm.
174 - Added initial support for updown scripts. The actions up-host/client and
175 down-host/client are executed. The leftfirewall=yes parameter
176 uses the default updown script to insert dynamic firewall rules, a custom
177 updown script may be specified with the leftupdown parameter.
183 - Added support for the auto=route ipsec.conf parameter and the
184 ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and
185 CHILD_SAs dynamically on demand when traffic is detected by the
188 - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter.
189 As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only
190 new keys are generated using perfect forward secrecy. An optional flag
191 which enforces reauthentication will be implemented later.
193 - "sha" and "sha1" are now treated as synonyms in the ike= and esp=
194 algorithm configuration statements.
200 - Full X.509 certificate trust chain verification has been implemented.
201 End entity certificates can be exchanged via CERT payloads. The current
202 default is leftsendcert=always, since CERTREQ payloads are not supported
203 yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls.
205 - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2
206 would offer more possibilities for traffic selection, but the Linux kernel
207 currently does not support it. That's why we stick with these simple
208 ipsec.conf rules for now.
210 - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no
211 IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear,
214 - Initial NAT traversal support in IKEv2. Charon includes NAT detection
215 notify payloads to detect NAT routers between the peers. It switches
216 to port 4500, uses UDP encapsulated ESP packets, handles peer address
217 changes gracefully and sends keep alive message periodically.
219 - Reimplemented IKE_SA state machine for charon, which allows simultaneous
220 rekeying, more shared code, cleaner design, proper retransmission
221 and a more extensible code base.
223 - The mixed PSK/RSA roadwarrior detection capability introduced by the
224 strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal
225 payloads by the responder right before any defined IKE Main Mode state had
226 been established. Although any form of bad proposal syntax was being correctly
227 detected by the payload parser, the subsequent error handler didn't check
228 the state pointer before logging current state information, causing an
229 immediate crash of the pluto keying daemon due to a NULL pointer.
235 - Added algorithm selection to charon: New default algorithms for
236 ike=aes128-sha-modp2048, as both daemons support it. The default
237 for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles
238 the ike/esp parameter the same way as pluto. As this syntax does
239 not allow specification of a pseudo random function, the same
240 algorithm as for integrity is used (currently sha/md5). Supported
242 Encryption: aes128, aes192, aes256
243 Integrity/PRF: md5, sha (using hmac)
244 DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192
246 Encryption: aes128, aes192, aes256, 3des, blowfish128,
247 blowfish192, blowfish256
249 More IKE encryption algorithms will come after porting libcrypto into
252 - initial support for rekeying CHILD_SAs using IKEv2. Currently no
253 perfect forward secrecy is used. The rekeying parameters rekey,
254 rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported
255 when using IKEv2. WARNING: charon currently is unable to handle
256 simultaneous rekeying. To avoid such a situation, use a large
257 rekeyfuzz, or even better, set rekey=no on one peer.
259 - support for host2host, net2net, host2net (roadwarrior) tunnels
260 using predefined RSA certificates (see uml scenarios for
261 configuration examples).
263 - new build environment featuring autotools. Features such
264 as HTTP, LDAP and smartcard support may be enabled using
265 the ./configure script. Changing install directories
266 is possible, too. See ./configure --help for more details.
268 - better integration of charon with ipsec starter, which allows
269 (almost) transparent operation with both daemons. charon
270 handles ipsec commands up, down, status, statusall, listall,
271 listcerts and allows proper load, reload and delete of connections
278 - initial support of the IKEv2 protocol. Connections in
279 ipsec.conf designated by keyexchange=ikev2 are negotiated
280 by the new IKEv2 charon keying daemon whereas those marked
281 by keyexchange=ikev1 or the default keyexchange=ike are
282 handled thy the IKEv1 pluto keying daemon. Currently only
283 a limited subset of functions are available with IKEv2
284 (Default AES encryption, authentication based on locally
285 imported X.509 certificates, unencrypted private RSA keys
286 in PKCS#1 file format, limited functionality of the ipsec
293 - the dynamic iptables rules from the _updown_x509 template
294 for KLIPS and the _updown_policy template for NETKEY have
295 been merged into the default _updown script. The existing
296 left|rightfirewall keyword causes the automatic insertion
297 and deletion of ACCEPT rules for tunneled traffic upon
298 the successful setup and teardown of an IPsec SA, respectively.
299 left|rightfirwall can be used with KLIPS under any Linux 2.4
300 kernel or with NETKEY under a Linux kernel version >= 2.6.16
301 in conjuction with iptables >= 1.3.5. For NETKEY under a Linux
302 kernel version < 2.6.16 which does not support IPsec policy
303 matching yet, please continue to use a copy of the _updown_espmark
304 template loaded via the left|rightupdown keyword.
306 - a new left|righthostaccess keyword has been introduced which
307 can be used in conjunction with left|rightfirewall and the
308 default _updown script. By default leftfirewall=yes inserts
309 a bi-directional iptables FORWARD rule for a local client network
310 with a netmask different from 255.255.255.255 (single host).
311 This does not allow to access the VPN gateway host via its
312 internal network interface which is part of the client subnet
313 because an iptables INPUT and OUTPUT rule would be required.
314 lefthostaccess=yes will cause this additional ACCEPT rules to
317 - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal
318 payload is preparsed in order to find out whether the roadwarrior
319 requests PSK or RSA so that a matching connection candidate can
326 - the new _updown_policy template allows ipsec policy based
327 iptables firewall rules. Required are iptables version
328 >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes
329 the _updown_espmark template, so that no INPUT mangle rules
330 are required any more.
332 - added support of DPD restart mode
334 - ipsec starter now allows the use of wildcards in include
335 statements as e.g. in "include /etc/my_ipsec/*.conf".
336 Patch courtesy of Matthias Haas.
338 - the Netscape OID 'employeeNumber' is now recognized and can be
339 used as a Relative Distinguished Name in certificates.
345 - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec
346 command and not of ipsec setup any more.
348 - ipsec starter now supports AH authentication in conjunction with
349 ESP encryption. AH authentication is configured in ipsec.conf
350 via the auth=ah parameter.
352 - The command ipsec scencrypt|scdecrypt <args> is now an alias for
353 ipsec whack --scencrypt|scdecrypt <args>.
355 - get_sa_info() now determines for the native netkey IPsec stack
356 the exact time of the last use of an active eroute. This information
357 is used by the Dead Peer Detection algorithm and is also displayed by
358 the ipsec status command.
364 - running under the native Linux 2.6 IPsec stack, the function
365 get_sa_info() is called by ipsec auto --status to display the current
366 number of transmitted bytes per IPsec SA.
368 - get_sa_info() is also used by the Dead Peer Detection process to detect
369 recent ESP activity. If ESP traffic was received from the peer within
370 the last dpd_delay interval then no R_Y_THERE notification must be sent.
372 - strongSwan now supports the Relative Distinguished Name "unstructuredName"
373 in ID_DER_ASN1_DN identities. The following notations are possible:
375 rightid="unstructuredName=John Doe"
376 rightid="UN=John Doe"
378 - fixed a long-standing bug which caused PSK-based roadwarrior connections
379 to segfault in the function id.c:same_id() called by keys.c:get_secret()
380 if an FQDN, USER_FQDN, or Key ID was defined, as in the following example.
387 - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall).
389 - ipsec starter didn't set host_addr and client.addr ports in whack msg.
391 - in order to guarantee backwards-compatibility with the script-based
392 auto function (e.g. auto --replace), the ipsec starter scripts stores
393 the defaultroute information in the temporary file /var/run/ipsec.info.
395 - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH
396 Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config
399 - the ipsec starter now also recognizes the parameters authby=never and
400 type=passthrough|pass|drop|reject.
406 - ipsec starter now supports the also parameter which allows
407 a modular structure of the connection definitions. Thus
408 "ipsec start" is now ready to replace "ipsec setup".
414 - Mathieu Lafon's popular ipsec starter tool has been added to the
415 strongSwan distribution. Many thanks go to Stephan Scholz from astaro
416 for his integration work. ipsec starter is a C program which is going
417 to replace the various shell and awk starter scripts (setup, _plutoload,
418 _plutostart, _realsetup, _startklips, _confread, and auto). Since
419 ipsec.conf is now parsed only once, the starting of multiple tunnels is
420 accelerated tremedously.
422 - Added support of %defaultroute to the ipsec starter. If the IP address
423 changes, a HUP signal to the ipsec starter will automatically
424 reload pluto's connections.
426 - moved most compile time configurations from pluto/Makefile to
427 Makefile.inc by defining the options USE_LIBCURL, USE_LDAP,
428 USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE.
430 - removed the ipsec verify and ipsec newhostkey commands
432 - fixed some 64-bit issues in formatted print statements
434 - The scepclient functionality implementing the Simple Certificate
435 Enrollment Protocol (SCEP) is nearly complete but hasn't been
442 - CA certicates are now automatically loaded from a smartcard
443 or USB crypto token and appear in the ipsec auto --listcacerts
450 - when using "ipsec whack --scencrypt <data>" with a PKCS#11
451 library that does not support the C_Encrypt() Cryptoki
452 function (e.g. OpenSC), the RSA encryption is done in
453 software using the public key fetched from the smartcard.
455 - The scepclient function now allows to define the
456 validity of a self-signed certificate using the --days,
457 --startdate, and --enddate options. The default validity
458 has been changed from one year to five years.
464 - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11
465 interface to other applications for RSA encryption and decryption
466 via the whack interface. Notation:
468 ipsec whack --scencrypt <data>
469 [--inbase 16|hex|64|base64|256|text|ascii]
470 [--outbase 16|hex|64|base64|256|text|ascii]
473 ipsec whack --scdecrypt <data>
474 [--inbase 16|hex|64|base64|256|text|ascii]
475 [--outbase 16|hex|64|base64|256|text|ascii]
478 The default setting for inbase and outbase is hex.
480 The new proxy interface can be used for securing symmetric
481 encryption keys required by the cryptoloop or dm-crypt
482 disk encryption schemes, especially in the case when
483 pkcs11keepstate=yes causes pluto to lock the pkcs11 slot
486 - if the file /etc/ipsec.secrets is lacking during the startup of
487 pluto then the root-readable file /etc/ipsec.d/private/myKey.der
488 containing a 2048 bit RSA private key and a matching self-signed
489 certificate stored in the file /etc/ipsec.d/certs/selfCert.der
490 is automatically generated by calling the function
492 ipsec scepclient --out pkcs1 --out cert-self
494 scepclient was written by Jan Hutter and Martin Willi, students
495 at the University of Applied Sciences in Rapperswil, Switzerland.
501 - the current extension of the PKCS#7 framework introduced
502 a parsing error in PKCS#7 wrapped X.509 certificates that are
503 e.g. transmitted by Windows XP when multi-level CAs are used.
504 the parsing syntax has been fixed.
506 - added a patch by Gerald Richter which tolerates multiple occurrences
507 of the ipsec0 interface when using KLIPS.
513 - with gawk-3.1.4 the word "default2 has become a protected
514 keyword for use in switch statements and cannot be used any
515 more in the strongSwan scripts. This problem has been
516 solved by renaming "default" to "defaults" and "setdefault"
517 in the scripts _confread and auto, respectively.
519 - introduced the parameter leftsendcert with the values
521 always|yes (the default, always send a cert)
522 ifasked (send the cert only upon a cert request)
523 never|no (never send a cert, used for raw RSA keys and
526 - fixed the initialization of the ESP key length to a default of
527 128 bits in the case that the peer does not send a key length
528 attribute for AES encryption.
530 - applied Herbert Xu's uniqueIDs patch
532 - applied Herbert Xu's CLOEXEC patches
538 - CRLs can now be cached also in the case when the issuer's
539 certificate does not contain a subjectKeyIdentifier field.
540 In that case the subjectKeyIdentifier is computed by pluto as the
541 160 bit SHA-1 hash of the issuer's public key in compliance
542 with section 4.2.1.2 of RFC 3280.
544 - Fixed a bug introduced by strongswan-2.5.1 which eliminated
545 not only multiple Quick Modes of a given connection but also
546 multiple connections between two security gateways.
552 - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute
553 installed either by setting auto=route in ipsec.conf or by
554 a connection put into hold, generates an XFRM_AQUIRE event
555 for each packet that wants to use the not-yet exisiting
556 tunnel. Up to now each XFRM_AQUIRE event led to an entry in
557 the Quick Mode queue, causing multiple IPsec SA to be
558 established in rapid succession. Starting with strongswan-2.5.1
559 only a single IPsec SA is established per host-pair connection.
561 - Right after loading the PKCS#11 module, all smartcard slots are
562 searched for certificates. The result can be viewed using
565 ipsec auto --listcards
567 The certificate objects found in the slots are numbered
568 starting with #1, #2, etc. This position number can be used to address
569 certificates (leftcert=%smartcard) and keys (: PIN %smartcard)
570 in ipsec.conf and ipsec.secrets, respectively:
572 %smartcard (selects object #1)
573 %smartcard#1 (selects object #1)
574 %smartcard#3 (selects object #3)
576 As an alternative the existing retrieval scheme can be used:
578 %smartcard:45 (selects object with id=45)
579 %smartcard0 (selects first object in slot 0)
580 %smartcard4:45 (selects object in slot 4 with id=45)
582 - Depending on the settings of CKA_SIGN and CKA_DECRYPT
583 private key flags either C_Sign() or C_Decrypt() is used
584 to generate a signature.
586 - The output buffer length parameter siglen in C_Sign()
587 is now initialized to the actual size of the output
588 buffer prior to the function call. This fixes the
589 CKR_BUFFER_TOO_SMALL error that could occur when using
590 the OpenSC PKCS#11 module.
592 - Changed the initialization of the PKCS#11 CK_MECHANISM in
593 C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }.
595 - Refactored the RSA public/private key code and transferred it
596 from keys.c to the new pkcs1.c file as a preparatory step
597 towards the release of the SCEP client.
603 - The loading of a PKCS#11 smartcard library module during
604 runtime does not require OpenSC library functions any more
605 because the corresponding code has been integrated into
606 smartcard.c. Also the RSAREF pkcs11 header files have been
607 included in a newly created pluto/rsaref directory so that
608 no external include path has to be defined any longer.
610 - A long-awaited feature has been implemented at last:
611 The local caching of CRLs fetched via HTTP or LDAP, activated
612 by the parameter cachecrls=yes in the config setup section
613 of ipsec.conf. The dynamically fetched CRLs are stored under
614 a unique file name containing the issuer's subjectKeyID
615 in /etc/ipsec.d/crls.
617 - Applied a one-line patch courtesy of Michael Richardson
618 from the Openswan project which fixes the kernel-oops
619 in KLIPS when an snmp daemon is running on the same box.
625 - Eliminated null length CRL distribution point strings.
627 - Fixed a trust path evaluation bug introduced with 2.4.3
633 - Improved the joint OCSP / CRL revocation policy.
634 OCSP responses have precedence over CRL entries.
636 - Introduced support of CRLv2 reason codes.
638 - Fixed a bug with key-pad equipped readers which caused
639 pluto to prompt for the pin via the console when the first
640 occasion to enter the pin via the key-pad was missed.
642 - When pluto is built with LDAP_V3 enabled, the library
643 liblber required by newer versions of openldap is now
650 - Added the _updown_espmark template which requires all
651 incoming ESP traffic to be marked with a default mark
654 - Introduced the pkcs11keepstate parameter in the config setup
655 section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11
656 session and login states are kept as long as possible during
657 the lifetime of pluto. This means that a PIN entry via a key
658 pad has to be done only once.
660 - Introduced the pkcs11module parameter in the config setup
661 section of ipsec.conf which specifies the PKCS#11 module
662 to be used with smart cards. Example:
664 pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo
666 - Added support of smartcard readers equipped with a PIN pad.
668 - Added patch by Jay Pfeifer which detects when netkey
669 modules have been statically built into the Linux 2.6 kernel.
671 - Added two patches by Herbert Xu. The first uses ip xfrm
672 instead of setkey to flush the IPsec policy database. The
673 second sets the optional flag in inbound IPComp SAs only.
675 - Applied Ulrich Weber's patch which fixes an interoperability
676 problem between native IPsec and KLIPS systems caused by
677 setting the replay window to 32 instead of 0 for ipcomp.
683 - Fixed a bug which caused an unwanted Mode Config request
684 to be initiated in the case where "right" was used to denote
685 the local side in ipsec.conf and "left" the remote side,
686 contrary to the recommendation that "right" be remote and
693 - updated Vendor ID to strongSwan-2.4.0
695 - updated copyright statement to include David Buechi and
702 - strongSwan now communicates with attached smartcards and
703 USB crypto tokens via the standardized PKCS #11 interface.
704 By default the OpenSC library from www.opensc.org is used
705 but any other PKCS#11 library could be dynamically linked.
706 strongSwan's PKCS#11 API was implemented by David Buechi
707 and Michael Meier, both graduates of the Zurich University
708 of Applied Sciences in Winterthur, Switzerland.
710 - When a %trap eroute is triggered by an outgoing IP packet
711 then the native IPsec stack of the Linux 2.6 kernel [often/
712 always?] returns an XFRM_ACQUIRE message with an undefined
713 protocol family field and the connection setup fails.
714 As a workaround IPv4 (AF_INET) is now assumed.
716 - the results of the UML test scenarios are now enhanced
717 with block diagrams of the virtual network topology used
718 in a particular test.
724 - fixed IV used to decrypt informational messages.
725 This bug was introduced with Mode Config functionality.
727 - fixed NCP Vendor ID.
729 - undid one of Ulrich Weber's maximum udp size patches
730 because it caused a segmentation fault with NAT-ed
733 - added UML scenarios wildcards and attr-cert which
734 demonstrate the implementation of IPsec policies based
735 on wildcard parameters contained in Distinguished Names and
736 on X.509 attribute certificates, respectively.
742 - Added basic Mode Config functionality
744 - Added Mathieu Lafon's patch which upgrades the status of
745 the NAT-Traversal implementation to RFC 3947.
747 - The _startklips script now also loads the xfrm4_tunnel
750 - Added Ulrich Weber's netlink replay window size and
751 maximum udp size patches.
753 - UML testing now uses the Linux 2.6.10 UML kernel by default.
759 - Eric Marchionni and Patrik Rayo, both recent graduates from
760 the Zuercher Hochschule Winterthur in Switzerland, created a
761 User-Mode-Linux test setup for strongSwan. For more details
762 please read the INSTALL and README documents in the testing
765 - Full support of group attributes based on X.509 attribute
766 certificates. Attribute certificates can be generated
767 using the openac facility. For more details see
771 The group attributes can be used in connection definitions
772 in order to give IPsec access to specific user groups.
773 This is done with the new parameter left|rightgroups as in
775 rightgroups="Research, Sales"
777 giving access to users possessing the group attributes
778 Research or Sales, only.
780 - In Quick Mode clients with subnet mask /32 are now
781 coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should
782 fix rekeying problems with the SafeNet/SoftRemote and NCP
783 Secure Entry Clients.
785 - Changed the defaults of the ikelifetime and keylife parameters
786 to 3h and 1h, respectively. The maximum allowable values are
787 now both set to 24 h.
789 - Suppressed notification wars between two IPsec peers that
790 could e.g. be triggered by incorrect ISAKMP encryption.
792 - Public RSA keys can now have identical IDs if either the
793 issuing CA or the serial number is different. The serial
794 number of a certificate is now shown by the command
796 ipsec auto --listpubkeys
802 - Added Tuomo Soini's sourceip feature which allows a strongSwan
803 roadwarrior to use a fixed Virtual IP (see README section 2.6)
804 and reduces the well-known four tunnel case on VPN gateways to
805 a single tunnel definition (see README section 2.4).
807 - Fixed a bug occuring with NAT-Traversal enabled when the responder
808 suddenly turns initiator and the initiator cannot find a matching
809 connection because of the floated IKE port 4500.
811 - Removed misleading ipsec verify command from barf.
813 - Running under the native IP stack, ipsec --version now shows
814 the Linux kernel version (courtesy to the Openswan project).
820 - Introduced the ipsec auto --listalgs monitoring command which lists
821 all currently registered IKE and ESP algorithms.
823 - Fixed a bug in the ESP algorithm selection occuring when the strict flag
824 is set and the first proposed transform does not match.
826 - Fixed another deadlock in the use of the lock_certs_and_keys() mutex,
827 occuring when a smartcard is present.
829 - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event.
831 - Fixed the printing of the notification names (null)
833 - Applied another of Herbert Xu's Netlink patches.
839 - Support of Dead Peer Detection. The connection parameter
843 activates DPD for the given connection.
845 - The default Opportunistic Encryption (OE) policy groups are not
846 automatically included anymore. Those wishing to activate OE can include
847 the policy group with the following statement in ipsec.conf:
849 include /etc/ipsec.d/examples/oe.conf
851 The default for [right|left]rsasigkey is now set to %cert.
853 - strongSwan now has a Vendor ID of its own which can be activated
854 using the compile option VENDORID
856 - Applied Herbert Xu's patch which sets the compression algorithm correctly.
858 - Applied Herbert Xu's patch fixing an ESPINUDP problem
860 - Applied Herbert Xu's patch setting source/destination port numbers.
862 - Reapplied one of Herbert Xu's NAT-Traversal patches which got
863 lost during the migration from SuperFreeS/WAN.
865 - Fixed a deadlock in the use of the lock_certs_and_keys() mutex.
867 - Fixed the unsharing of alg parameters when instantiating group
874 - Thomas Walpuski made me aware of a potential DoS attack via
875 a PKCS#7-wrapped certificate bundle which could overwrite valid CA
876 certificates in Pluto's authority certificate store. This vulnerability
877 was fixed by establishing trust in CA candidate certificates up to a
878 trusted root CA prior to insertion into Pluto's chained list.
880 - replaced the --assign option by the -v option in the auto awk script
881 in order to make it run with mawk under debian/woody.
887 - Split of the status information between ipsec auto --status (concise)
888 and ipsec auto --statusall (verbose). Both commands can be used with
889 an optional connection selector:
891 ipsec auto --status[all] <connection_name>
893 - Added the description of X.509 related features to the ipsec_auto(8)
896 - Hardened the ASN.1 parser in debug mode, especially the printing
897 of malformed distinguished names.
899 - The size of an RSA public key received in a certificate is now restricted to
901 512 bits <= modulus length <= 8192 bits.
903 - Fixed the debug mode enumeration.
909 - Fixed another PKCS#7 vulnerability which could lead to an
910 endless loop while following the X.509 trust chain.
916 - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski
917 that accepted end certificates having identical issuer and subject
918 distinguished names in a multi-tier X.509 trust chain.
924 - Removed all remaining references to ipsec_netlink.h in KLIPS.
930 - The new "ca" section allows to define the following parameters:
933 cacert=koolCA.pem # cacert of kool CA
934 ocspuri=http://ocsp.kool.net:8001 # ocsp server
935 ldapserver=ldap.kool.net # default ldap server
936 crluri=http://www.kool.net/kool.crl # crl distribution point
937 crluri2="ldap:///O=Kool, C= .." # crl distribution point #2
938 auto=add # add, ignore
940 The ca definitions can be monitored via the command
942 ipsec auto --listcainfos
944 - Fixed cosmetic corruption of /proc filesystem by integrating
945 D. Hugh Redelmeier's freeswan-2.06 kernel fixes.
951 - Added support for the 818043 NAT-Traversal update of Microsoft's
952 Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode.
954 - A symbolic link to libcrypto is now added in the kernel sources
955 during kernel compilation
957 - Fixed a couple of 64 bit issues (mostly casts to int).
958 Thanks to Ken Bantoft who checked my sources on a 64 bit platform.
960 - Replaced s[n]printf() statements in the kernel by ipsec_snprintf().
961 Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro
962 of the FreeS/WAN team who solved this problem with the 2.4.25 kernel.
968 - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName
969 certificate extension which contains no generalName item) can cause
970 a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has
971 been hardened to make it more robust against malformed ASN.1 objects.
973 - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native
974 Linux 2.6 IPsec stack.
980 - based on freeswan-2.04, x509-1.5.3, nat-0.6c, alg-0.8.1rc12
