4 - Support of SHA2_384 hash function for protecting IKEv1
5 negotiations and support of SHA2 signatures in X.509 certificates.
7 - Fixed a serious bug in the computation of the SHA2-512 HMAC
8 function. Introduced automatic self-test of all IKEv1 hash
9 and hmac functions during pluto startup. Failure of a self-test
10 currently issues a warning only but does not exit pluto [yet].
12 - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2.
14 - Full support of CA information sections. ipsec listcainfos
15 now shows all collected crlDistributionPoints and OCSP
18 - Refactored core of the IKEv2 message processing code, allowing better
19 code reuse and separation.
21 - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration
22 payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted
23 by the requestor and installed in a resolv.conf file.
25 - The IKEv2 daemon charon installs a route for each IPsec policy to use
26 the correct source address even if an application does not explicitly
29 - Integrated the EAP framework into charon which loads pluggable EAP library
30 modules. The ipsec.conf parameter authby=eap initiates EAP authentication
31 on the client side, while the "eap" parameter on the server side defines
32 the EAP method to use for client authentication.
33 A generic client side EAP-Identity module and an EAP-SIM authentication
34 module using a third party card reader implementation are included.
36 - Added client side support for cookies.
38 - Integrated the fixes done at the IKEv2 interoperability bakeoff, including
39 strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor
40 fixes to enhance interoperability with other implementations.
45 - strongSwan now interoperates with the NCP Secure Entry Client,
46 the Shrew Soft VPN Client, and the Cisco VPN client, doing both
47 XAUTH and Mode Config.
49 - UNITY attributes are now recognized and UNITY_BANNER is set
56 - IKEv1: Support for extended authentication (XAUTH) in combination
57 with ISAKMP Main Mode RSA or PSK authentication. Both client and
58 server side were implemented. Handling of user credentials can
59 be done by a run-time loadable XAUTH module. By default user
60 credentials are stored in ipsec.secrets.
62 - IKEv2: Support for reauthentication when rekeying
64 - IKEv2: Support for transport mode
66 - fixed a lot of bugs related to byte order
68 - various other bugfixes
74 - IKEv1: Implementation of ModeConfig push mode via the new connection
75 keyword modeconfig=push allows interoperability with Cisco VPN gateways.
77 - IKEv1: The command ipsec statusall now shows "DPD active" for all
78 ISAKMP SAs that are under active Dead Peer Detection control.
80 - IKEv2: Charon's logging and debugging framework has been completely rewritten.
81 Instead of logger, special printf() functions are used to directly
82 print objects like hosts (%H) identifications (%D), certificates (%Q),
83 etc. The number of debugging levels have been reduced to:
85 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private)
87 The debugging levels can either be specified statically in ipsec.conf as
90 charondebug="lib 1, cfg 3, net 2"
92 or changed at runtime via stroke as
94 ipsec stroke loglevel cfg 2
100 - Implemented full support for IPv6-in-IPv6 tunnels.
102 - Added configuration options for dead peer detection in IKEv2. dpd_action
103 types "clear", "hold" and "restart" are supported. The dpd_timeout
104 value is not used, as the normal retransmission policy applies to
105 detect dead peers. The dpd_delay parameter enables sending of empty
106 informational message to detect dead peers in case of inactivity.
108 - Added support for preshared keys in IKEv2. PSK keys configured in
109 ipsec.secrets are loaded. The authby parameter specifies the authentication
110 method to authentificate ourself, the other peer may use PSK or RSA.
112 - Changed retransmission policy to respect the keyingtries parameter.
114 - Added private key decryption. PEM keys encrypted with AES-128/192/256
115 or 3DES are supported.
117 - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to
120 - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates
121 signed with such a hash algorithm.
123 - Added initial support for updown scripts. The actions up-host/client and
124 down-host/client are executed. The leftfirewall=yes parameter
125 uses the default updown script to insert dynamic firewall rules, a custom
126 updown script may be specified with the leftupdown parameter.
132 - Added support for the auto=route ipsec.conf parameter and the
133 ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and
134 CHILD_SAs dynamically on demand when traffic is detected by the
137 - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter.
138 As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only
139 new keys are generated using perfect forward secrecy. An optional flag
140 which enforces reauthentication will be implemented later.
142 - "sha" and "sha1" are now treated as synonyms in the ike= and esp=
143 algorithm configuration statements.
149 - Full X.509 certificate trust chain verification has been implemented.
150 End entity certificates can be exchanged via CERT payloads. The current
151 default is leftsendcert=always, since CERTREQ payloads are not supported
152 yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls.
154 - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2
155 would offer more possibilities for traffic selection, but the Linux kernel
156 currently does not support it. That's why we stick with these simple
157 ipsec.conf rules for now.
159 - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no
160 IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear,
163 - Initial NAT traversal support in IKEv2. Charon includes NAT detection
164 notify payloads to detect NAT routers between the peers. It switches
165 to port 4500, uses UDP encapsulated ESP packets, handles peer address
166 changes gracefully and sends keep alive message periodically.
168 - Reimplemented IKE_SA state machine for charon, which allows simultaneous
169 rekeying, more shared code, cleaner design, proper retransmission
170 and a more extensible code base.
172 - The mixed PSK/RSA roadwarrior detection capability introduced by the
173 strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal
174 payloads by the responder right before any defined IKE Main Mode state had
175 been established. Although any form of bad proposal syntax was being correctly
176 detected by the payload parser, the subsequent error handler didn't check
177 the state pointer before logging current state information, causing an
178 immediate crash of the pluto keying daemon due to a NULL pointer.
184 - Added algorithm selection to charon: New default algorithms for
185 ike=aes128-sha-modp2048, as both daemons support it. The default
186 for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles
187 the ike/esp parameter the same way as pluto. As this syntax does
188 not allow specification of a pseudo random function, the same
189 algorithm as for integrity is used (currently sha/md5). Supported
191 Encryption: aes128, aes192, aes256
192 Integrity/PRF: md5, sha (using hmac)
193 DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192
195 Encryption: aes128, aes192, aes256, 3des, blowfish128,
196 blowfish192, blowfish256
198 More IKE encryption algorithms will come after porting libcrypto into
201 - initial support for rekeying CHILD_SAs using IKEv2. Currently no
202 perfect forward secrecy is used. The rekeying parameters rekey,
203 rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported
204 when using IKEv2. WARNING: charon currently is unable to handle
205 simultaneous rekeying. To avoid such a situation, use a large
206 rekeyfuzz, or even better, set rekey=no on one peer.
208 - support for host2host, net2net, host2net (roadwarrior) tunnels
209 using predefined RSA certificates (see uml scenarios for
210 configuration examples).
212 - new build environment featuring autotools. Features such
213 as HTTP, LDAP and smartcard support may be enabled using
214 the ./configure script. Changing install directories
215 is possible, too. See ./configure --help for more details.
217 - better integration of charon with ipsec starter, which allows
218 (almost) transparent operation with both daemons. charon
219 handles ipsec commands up, down, status, statusall, listall,
220 listcerts and allows proper load, reload and delete of connections
227 - initial support of the IKEv2 protocol. Connections in
228 ipsec.conf designated by keyexchange=ikev2 are negotiated
229 by the new IKEv2 charon keying daemon whereas those marked
230 by keyexchange=ikev1 or the default keyexchange=ike are
231 handled thy the IKEv1 pluto keying daemon. Currently only
232 a limited subset of functions are available with IKEv2
233 (Default AES encryption, authentication based on locally
234 imported X.509 certificates, unencrypted private RSA keys
235 in PKCS#1 file format, limited functionality of the ipsec
242 - the dynamic iptables rules from the _updown_x509 template
243 for KLIPS and the _updown_policy template for NETKEY have
244 been merged into the default _updown script. The existing
245 left|rightfirewall keyword causes the automatic insertion
246 and deletion of ACCEPT rules for tunneled traffic upon
247 the successful setup and teardown of an IPsec SA, respectively.
248 left|rightfirwall can be used with KLIPS under any Linux 2.4
249 kernel or with NETKEY under a Linux kernel version >= 2.6.16
250 in conjuction with iptables >= 1.3.5. For NETKEY under a Linux
251 kernel version < 2.6.16 which does not support IPsec policy
252 matching yet, please continue to use a copy of the _updown_espmark
253 template loaded via the left|rightupdown keyword.
255 - a new left|righthostaccess keyword has been introduced which
256 can be used in conjunction with left|rightfirewall and the
257 default _updown script. By default leftfirewall=yes inserts
258 a bi-directional iptables FORWARD rule for a local client network
259 with a netmask different from 255.255.255.255 (single host).
260 This does not allow to access the VPN gateway host via its
261 internal network interface which is part of the client subnet
262 because an iptables INPUT and OUTPUT rule would be required.
263 lefthostaccess=yes will cause this additional ACCEPT rules to
266 - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal
267 payload is preparsed in order to find out whether the roadwarrior
268 requests PSK or RSA so that a matching connection candidate can
275 - the new _updown_policy template allows ipsec policy based
276 iptables firewall rules. Required are iptables version
277 >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes
278 the _updown_espmark template, so that no INPUT mangle rules
279 are required any more.
281 - added support of DPD restart mode
283 - ipsec starter now allows the use of wildcards in include
284 statements as e.g. in "include /etc/my_ipsec/*.conf".
285 Patch courtesy of Matthias Haas.
287 - the Netscape OID 'employeeNumber' is now recognized and can be
288 used as a Relative Distinguished Name in certificates.
294 - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec
295 command and not of ipsec setup any more.
297 - ipsec starter now supports AH authentication in conjunction with
298 ESP encryption. AH authentication is configured in ipsec.conf
299 via the auth=ah parameter.
301 - The command ipsec scencrypt|scdecrypt <args> is now an alias for
302 ipsec whack --scencrypt|scdecrypt <args>.
304 - get_sa_info() now determines for the native netkey IPsec stack
305 the exact time of the last use of an active eroute. This information
306 is used by the Dead Peer Detection algorithm and is also displayed by
307 the ipsec status command.
313 - running under the native Linux 2.6 IPsec stack, the function
314 get_sa_info() is called by ipsec auto --status to display the current
315 number of transmitted bytes per IPsec SA.
317 - get_sa_info() is also used by the Dead Peer Detection process to detect
318 recent ESP activity. If ESP traffic was received from the peer within
319 the last dpd_delay interval then no R_Y_THERE notification must be sent.
321 - strongSwan now supports the Relative Distinguished Name "unstructuredName"
322 in ID_DER_ASN1_DN identities. The following notations are possible:
324 rightid="unstructuredName=John Doe"
325 rightid="UN=John Doe"
327 - fixed a long-standing bug which caused PSK-based roadwarrior connections
328 to segfault in the function id.c:same_id() called by keys.c:get_secret()
329 if an FQDN, USER_FQDN, or Key ID was defined, as in the following example.
336 - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall).
338 - ipsec starter didn't set host_addr and client.addr ports in whack msg.
340 - in order to guarantee backwards-compatibility with the script-based
341 auto function (e.g. auto --replace), the ipsec starter scripts stores
342 the defaultroute information in the temporary file /var/run/ipsec.info.
344 - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH
345 Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config
348 - the ipsec starter now also recognizes the parameters authby=never and
349 type=passthrough|pass|drop|reject.
355 - ipsec starter now supports the also parameter which allows
356 a modular structure of the connection definitions. Thus
357 "ipsec start" is now ready to replace "ipsec setup".
363 - Mathieu Lafon's popular ipsec starter tool has been added to the
364 strongSwan distribution. Many thanks go to Stephan Scholz from astaro
365 for his integration work. ipsec starter is a C program which is going
366 to replace the various shell and awk starter scripts (setup, _plutoload,
367 _plutostart, _realsetup, _startklips, _confread, and auto). Since
368 ipsec.conf is now parsed only once, the starting of multiple tunnels is
369 accelerated tremedously.
371 - Added support of %defaultroute to the ipsec starter. If the IP address
372 changes, a HUP signal to the ipsec starter will automatically
373 reload pluto's connections.
375 - moved most compile time configurations from pluto/Makefile to
376 Makefile.inc by defining the options USE_LIBCURL, USE_LDAP,
377 USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE.
379 - removed the ipsec verify and ipsec newhostkey commands
381 - fixed some 64-bit issues in formatted print statements
383 - The scepclient functionality implementing the Simple Certificate
384 Enrollment Protocol (SCEP) is nearly complete but hasn't been
391 - CA certicates are now automatically loaded from a smartcard
392 or USB crypto token and appear in the ipsec auto --listcacerts
399 - when using "ipsec whack --scencrypt <data>" with a PKCS#11
400 library that does not support the C_Encrypt() Cryptoki
401 function (e.g. OpenSC), the RSA encryption is done in
402 software using the public key fetched from the smartcard.
404 - The scepclient function now allows to define the
405 validity of a self-signed certificate using the --days,
406 --startdate, and --enddate options. The default validity
407 has been changed from one year to five years.
413 - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11
414 interface to other applications for RSA encryption and decryption
415 via the whack interface. Notation:
417 ipsec whack --scencrypt <data>
418 [--inbase 16|hex|64|base64|256|text|ascii]
419 [--outbase 16|hex|64|base64|256|text|ascii]
422 ipsec whack --scdecrypt <data>
423 [--inbase 16|hex|64|base64|256|text|ascii]
424 [--outbase 16|hex|64|base64|256|text|ascii]
427 The default setting for inbase and outbase is hex.
429 The new proxy interface can be used for securing symmetric
430 encryption keys required by the cryptoloop or dm-crypt
431 disk encryption schemes, especially in the case when
432 pkcs11keepstate=yes causes pluto to lock the pkcs11 slot
435 - if the file /etc/ipsec.secrets is lacking during the startup of
436 pluto then the root-readable file /etc/ipsec.d/private/myKey.der
437 containing a 2048 bit RSA private key and a matching self-signed
438 certificate stored in the file /etc/ipsec.d/certs/selfCert.der
439 is automatically generated by calling the function
441 ipsec scepclient --out pkcs1 --out cert-self
443 scepclient was written by Jan Hutter and Martin Willi, students
444 at the University of Applied Sciences in Rapperswil, Switzerland.
450 - the current extension of the PKCS#7 framework introduced
451 a parsing error in PKCS#7 wrapped X.509 certificates that are
452 e.g. transmitted by Windows XP when multi-level CAs are used.
453 the parsing syntax has been fixed.
455 - added a patch by Gerald Richter which tolerates multiple occurrences
456 of the ipsec0 interface when using KLIPS.
462 - with gawk-3.1.4 the word "default2 has become a protected
463 keyword for use in switch statements and cannot be used any
464 more in the strongSwan scripts. This problem has been
465 solved by renaming "default" to "defaults" and "setdefault"
466 in the scripts _confread and auto, respectively.
468 - introduced the parameter leftsendcert with the values
470 always|yes (the default, always send a cert)
471 ifasked (send the cert only upon a cert request)
472 never|no (never send a cert, used for raw RSA keys and
475 - fixed the initialization of the ESP key length to a default of
476 128 bits in the case that the peer does not send a key length
477 attribute for AES encryption.
479 - applied Herbert Xu's uniqueIDs patch
481 - applied Herbert Xu's CLOEXEC patches
487 - CRLs can now be cached also in the case when the issuer's
488 certificate does not contain a subjectKeyIdentifier field.
489 In that case the subjectKeyIdentifier is computed by pluto as the
490 160 bit SHA-1 hash of the issuer's public key in compliance
491 with section 4.2.1.2 of RFC 3280.
493 - Fixed a bug introduced by strongswan-2.5.1 which eliminated
494 not only multiple Quick Modes of a given connection but also
495 multiple connections between two security gateways.
501 - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute
502 installed either by setting auto=route in ipsec.conf or by
503 a connection put into hold, generates an XFRM_AQUIRE event
504 for each packet that wants to use the not-yet exisiting
505 tunnel. Up to now each XFRM_AQUIRE event led to an entry in
506 the Quick Mode queue, causing multiple IPsec SA to be
507 established in rapid succession. Starting with strongswan-2.5.1
508 only a single IPsec SA is established per host-pair connection.
510 - Right after loading the PKCS#11 module, all smartcard slots are
511 searched for certificates. The result can be viewed using
514 ipsec auto --listcards
516 The certificate objects found in the slots are numbered
517 starting with #1, #2, etc. This position number can be used to address
518 certificates (leftcert=%smartcard) and keys (: PIN %smartcard)
519 in ipsec.conf and ipsec.secrets, respectively:
521 %smartcard (selects object #1)
522 %smartcard#1 (selects object #1)
523 %smartcard#3 (selects object #3)
525 As an alternative the existing retrieval scheme can be used:
527 %smartcard:45 (selects object with id=45)
528 %smartcard0 (selects first object in slot 0)
529 %smartcard4:45 (selects object in slot 4 with id=45)
531 - Depending on the settings of CKA_SIGN and CKA_DECRYPT
532 private key flags either C_Sign() or C_Decrypt() is used
533 to generate a signature.
535 - The output buffer length parameter siglen in C_Sign()
536 is now initialized to the actual size of the output
537 buffer prior to the function call. This fixes the
538 CKR_BUFFER_TOO_SMALL error that could occur when using
539 the OpenSC PKCS#11 module.
541 - Changed the initialization of the PKCS#11 CK_MECHANISM in
542 C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }.
544 - Refactored the RSA public/private key code and transferred it
545 from keys.c to the new pkcs1.c file as a preparatory step
546 towards the release of the SCEP client.
552 - The loading of a PKCS#11 smartcard library module during
553 runtime does not require OpenSC library functions any more
554 because the corresponding code has been integrated into
555 smartcard.c. Also the RSAREF pkcs11 header files have been
556 included in a newly created pluto/rsaref directory so that
557 no external include path has to be defined any longer.
559 - A long-awaited feature has been implemented at last:
560 The local caching of CRLs fetched via HTTP or LDAP, activated
561 by the parameter cachecrls=yes in the config setup section
562 of ipsec.conf. The dynamically fetched CRLs are stored under
563 a unique file name containing the issuer's subjectKeyID
564 in /etc/ipsec.d/crls.
566 - Applied a one-line patch courtesy of Michael Richardson
567 from the Openswan project which fixes the kernel-oops
568 in KLIPS when an snmp daemon is running on the same box.
574 - Eliminated null length CRL distribution point strings.
576 - Fixed a trust path evaluation bug introduced with 2.4.3
582 - Improved the joint OCSP / CRL revocation policy.
583 OCSP responses have precedence over CRL entries.
585 - Introduced support of CRLv2 reason codes.
587 - Fixed a bug with key-pad equipped readers which caused
588 pluto to prompt for the pin via the console when the first
589 occasion to enter the pin via the key-pad was missed.
591 - When pluto is built with LDAP_V3 enabled, the library
592 liblber required by newer versions of openldap is now
599 - Added the _updown_espmark template which requires all
600 incoming ESP traffic to be marked with a default mark
603 - Introduced the pkcs11keepstate parameter in the config setup
604 section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11
605 session and login states are kept as long as possible during
606 the lifetime of pluto. This means that a PIN entry via a key
607 pad has to be done only once.
609 - Introduced the pkcs11module parameter in the config setup
610 section of ipsec.conf which specifies the PKCS#11 module
611 to be used with smart cards. Example:
613 pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo
615 - Added support of smartcard readers equipped with a PIN pad.
617 - Added patch by Jay Pfeifer which detects when netkey
618 modules have been statically built into the Linux 2.6 kernel.
620 - Added two patches by Herbert Xu. The first uses ip xfrm
621 instead of setkey to flush the IPsec policy database. The
622 second sets the optional flag in inbound IPComp SAs only.
624 - Applied Ulrich Weber's patch which fixes an interoperability
625 problem between native IPsec and KLIPS systems caused by
626 setting the replay window to 32 instead of 0 for ipcomp.
632 - Fixed a bug which caused an unwanted Mode Config request
633 to be initiated in the case where "right" was used to denote
634 the local side in ipsec.conf and "left" the remote side,
635 contrary to the recommendation that "right" be remote and
642 - updated Vendor ID to strongSwan-2.4.0
644 - updated copyright statement to include David Buechi and
651 - strongSwan now communicates with attached smartcards and
652 USB crypto tokens via the standardized PKCS #11 interface.
653 By default the OpenSC library from www.opensc.org is used
654 but any other PKCS#11 library could be dynamically linked.
655 strongSwan's PKCS#11 API was implemented by David Buechi
656 and Michael Meier, both graduates of the Zurich University
657 of Applied Sciences in Winterthur, Switzerland.
659 - When a %trap eroute is triggered by an outgoing IP packet
660 then the native IPsec stack of the Linux 2.6 kernel [often/
661 always?] returns an XFRM_ACQUIRE message with an undefined
662 protocol family field and the connection setup fails.
663 As a workaround IPv4 (AF_INET) is now assumed.
665 - the results of the UML test scenarios are now enhanced
666 with block diagrams of the virtual network topology used
667 in a particular test.
673 - fixed IV used to decrypt informational messages.
674 This bug was introduced with Mode Config functionality.
676 - fixed NCP Vendor ID.
678 - undid one of Ulrich Weber's maximum udp size patches
679 because it caused a segmentation fault with NAT-ed
682 - added UML scenarios wildcards and attr-cert which
683 demonstrate the implementation of IPsec policies based
684 on wildcard parameters contained in Distinguished Names and
685 on X.509 attribute certificates, respectively.
691 - Added basic Mode Config functionality
693 - Added Mathieu Lafon's patch which upgrades the status of
694 the NAT-Traversal implementation to RFC 3947.
696 - The _startklips script now also loads the xfrm4_tunnel
699 - Added Ulrich Weber's netlink replay window size and
700 maximum udp size patches.
702 - UML testing now uses the Linux 2.6.10 UML kernel by default.
708 - Eric Marchionni and Patrik Rayo, both recent graduates from
709 the Zuercher Hochschule Winterthur in Switzerland, created a
710 User-Mode-Linux test setup for strongSwan. For more details
711 please read the INSTALL and README documents in the testing
714 - Full support of group attributes based on X.509 attribute
715 certificates. Attribute certificates can be generated
716 using the openac facility. For more details see
720 The group attributes can be used in connection definitions
721 in order to give IPsec access to specific user groups.
722 This is done with the new parameter left|rightgroups as in
724 rightgroups="Research, Sales"
726 giving access to users possessing the group attributes
727 Research or Sales, only.
729 - In Quick Mode clients with subnet mask /32 are now
730 coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should
731 fix rekeying problems with the SafeNet/SoftRemote and NCP
732 Secure Entry Clients.
734 - Changed the defaults of the ikelifetime and keylife parameters
735 to 3h and 1h, respectively. The maximum allowable values are
736 now both set to 24 h.
738 - Suppressed notification wars between two IPsec peers that
739 could e.g. be triggered by incorrect ISAKMP encryption.
741 - Public RSA keys can now have identical IDs if either the
742 issuing CA or the serial number is different. The serial
743 number of a certificate is now shown by the command
745 ipsec auto --listpubkeys
751 - Added Tuomo Soini's sourceip feature which allows a strongSwan
752 roadwarrior to use a fixed Virtual IP (see README section 2.6)
753 and reduces the well-known four tunnel case on VPN gateways to
754 a single tunnel definition (see README section 2.4).
756 - Fixed a bug occuring with NAT-Traversal enabled when the responder
757 suddenly turns initiator and the initiator cannot find a matching
758 connection because of the floated IKE port 4500.
760 - Removed misleading ipsec verify command from barf.
762 - Running under the native IP stack, ipsec --version now shows
763 the Linux kernel version (courtesy to the Openswan project).
769 - Introduced the ipsec auto --listalgs monitoring command which lists
770 all currently registered IKE and ESP algorithms.
772 - Fixed a bug in the ESP algorithm selection occuring when the strict flag
773 is set and the first proposed transform does not match.
775 - Fixed another deadlock in the use of the lock_certs_and_keys() mutex,
776 occuring when a smartcard is present.
778 - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event.
780 - Fixed the printing of the notification names (null)
782 - Applied another of Herbert Xu's Netlink patches.
788 - Support of Dead Peer Detection. The connection parameter
792 activates DPD for the given connection.
794 - The default Opportunistic Encryption (OE) policy groups are not
795 automatically included anymore. Those wishing to activate OE can include
796 the policy group with the following statement in ipsec.conf:
798 include /etc/ipsec.d/examples/oe.conf
800 The default for [right|left]rsasigkey is now set to %cert.
802 - strongSwan now has a Vendor ID of its own which can be activated
803 using the compile option VENDORID
805 - Applied Herbert Xu's patch which sets the compression algorithm correctly.
807 - Applied Herbert Xu's patch fixing an ESPINUDP problem
809 - Applied Herbert Xu's patch setting source/destination port numbers.
811 - Reapplied one of Herbert Xu's NAT-Traversal patches which got
812 lost during the migration from SuperFreeS/WAN.
814 - Fixed a deadlock in the use of the lock_certs_and_keys() mutex.
816 - Fixed the unsharing of alg parameters when instantiating group
823 - Thomas Walpuski made me aware of a potential DoS attack via
824 a PKCS#7-wrapped certificate bundle which could overwrite valid CA
825 certificates in Pluto's authority certificate store. This vulnerability
826 was fixed by establishing trust in CA candidate certificates up to a
827 trusted root CA prior to insertion into Pluto's chained list.
829 - replaced the --assign option by the -v option in the auto awk script
830 in order to make it run with mawk under debian/woody.
836 - Split of the status information between ipsec auto --status (concise)
837 and ipsec auto --statusall (verbose). Both commands can be used with
838 an optional connection selector:
840 ipsec auto --status[all] <connection_name>
842 - Added the description of X.509 related features to the ipsec_auto(8)
845 - Hardened the ASN.1 parser in debug mode, especially the printing
846 of malformed distinguished names.
848 - The size of an RSA public key received in a certificate is now restricted to
850 512 bits <= modulus length <= 8192 bits.
852 - Fixed the debug mode enumeration.
858 - Fixed another PKCS#7 vulnerability which could lead to an
859 endless loop while following the X.509 trust chain.
865 - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski
866 that accepted end certificates having identical issuer and subject
867 distinguished names in a multi-tier X.509 trust chain.
873 - Removed all remaining references to ipsec_netlink.h in KLIPS.
879 - The new "ca" section allows to define the following parameters:
882 cacert=koolCA.pem # cacert of kool CA
883 ocspuri=http://ocsp.kool.net:8001 # ocsp server
884 ldapserver=ldap.kool.net # default ldap server
885 crluri=http://www.kool.net/kool.crl # crl distribution point
886 crluri2="ldap:///O=Kool, C= .." # crl distribution point #2
887 auto=add # add, ignore
889 The ca definitions can be monitored via the command
891 ipsec auto --listcainfos
893 - Fixed cosmetic corruption of /proc filesystem by integrating
894 D. Hugh Redelmeier's freeswan-2.06 kernel fixes.
900 - Added support for the 818043 NAT-Traversal update of Microsoft's
901 Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode.
903 - A symbolic link to libcrypto is now added in the kernel sources
904 during kernel compilation
906 - Fixed a couple of 64 bit issues (mostly casts to int).
907 Thanks to Ken Bantoft who checked my sources on a 64 bit platform.
909 - Replaced s[n]printf() statements in the kernel by ipsec_snprintf().
910 Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro
911 of the FreeS/WAN team who solved this problem with the 2.4.25 kernel.
917 - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName
918 certificate extension which contains no generalName item) can cause
919 a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has
920 been hardened to make it more robust against malformed ASN.1 objects.
922 - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native
923 Linux 2.6 IPsec stack.
929 - based on freeswan-2.04, x509-1.5.3, nat-0.6c, alg-0.8.1rc12
