4 - IKEv2: Support for reauthentication when rekeying
6 - IKEv2: Support for transport and (experimental!) BEET mode
8 - fixed most (all?) bugs related to byte order
10 - a lot of other bugfixes
16 - IKEv1: Implementation of ModeConfig push mode via the new connection
17 keyword modeconfig=push allows interoperability with Cisco VPN gateways.
19 - IKEv1: The command ipsec statusall now shows "DPD active" for all
20 ISAKMP SAs that are under active Dead Peer Detection control.
22 - IKEv2: Charon's logging and debugging framework has been completely rewritten.
23 Instead of logger, special printf() functions are used to directly
24 print objects like hosts (%H) identifications (%D), certificates (%Q),
25 etc. The number of debugging levels have been reduced to:
27 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private)
29 The debugging levels can either be specified statically in ipsec.conf as
32 charondebug="lib 1, cfg 3, net 2"
34 or changed at runtime via stroke as
36 ipsec stroke loglevel cfg 2
42 - Implemented full support for IPv6-in-IPv6 tunnels.
44 - Added configuration options for dead peer detection in IKEv2. dpd_action
45 types "clear", "hold" and "restart" are supported. The dpd_timeout
46 value is not used, as the normal retransmission policy applies to
47 detect dead peers. The dpd_delay parameter enables sending of empty
48 informational message to detect dead peers in case of inactivity.
50 - Added support for preshared keys in IKEv2. PSK keys configured in
51 ipsec.secrets are loaded. The authby parameter specifies the authentication
52 method to authentificate ourself, the other peer may use PSK or RSA.
54 - Changed retransmission policy to respect the keyingtries parameter.
56 - Added private key decryption. PEM keys encrypted with AES-128/192/256
57 or 3DES are supported.
59 - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to
62 - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates
63 signed with such a hash algorithm.
65 - Added initial support for updown scripts. The actions up-host/client and
66 down-host/client are executed. The leftfirewall=yes parameter
67 uses the default updown script to insert dynamic firewall rules, a custom
68 updown script may be specified with the leftupdown parameter.
74 - Added support for the auto=route ipsec.conf parameter and the
75 ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and
76 CHILD_SAs dynamically on demand when traffic is detected by the
79 - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter.
80 As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only
81 new keys are generated using perfect forward secrecy. An optional flag
82 which enforces reauthentication will be implemented later.
84 - "sha" and "sha1" are now treated as synonyms in the ike= and esp=
85 algorithm configuration statements.
91 - Full X.509 certificate trust chain verification has been implemented.
92 End entity certificates can be exchanged via CERT payloads. The current
93 default is leftsendcert=always, since CERTREQ payloads are not supported
94 yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls.
96 - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2
97 would offer more possibilities for traffic selection, but the Linux kernel
98 currently does not support it. That's why we stick with these simple
99 ipsec.conf rules for now.
101 - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no
102 IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear,
105 - Initial NAT traversal support in IKEv2. Charon includes NAT detection
106 notify payloads to detect NAT routers between the peers. It switches
107 to port 4500, uses UDP encapsulated ESP packets, handles peer address
108 changes gracefully and sends keep alive message periodically.
110 - Reimplemented IKE_SA state machine for charon, which allows simultaneous
111 rekeying, more shared code, cleaner design, proper retransmission
112 and a more extensible code base.
114 - The mixed PSK/RSA roadwarrior detection capability introduced by the
115 strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal
116 payloads by the responder right before any defined IKE Main Mode state had
117 been established. Although any form of bad proposal syntax was being correctly
118 detected by the payload parser, the subsequent error handler didn't check
119 the state pointer before logging current state information, causing an
120 immediate crash of the pluto keying daemon due to a NULL pointer.
126 - Added algorithm selection to charon: New default algorithms for
127 ike=aes128-sha-modp2048, as both daemons support it. The default
128 for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles
129 the ike/esp parameter the same way as pluto. As this syntax does
130 not allow specification of a pseudo random function, the same
131 algorithm as for integrity is used (currently sha/md5). Supported
133 Encryption: aes128, aes192, aes256
134 Integrity/PRF: md5, sha (using hmac)
135 DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192
137 Encryption: aes128, aes192, aes256, 3des, blowfish128,
138 blowfish192, blowfish256
140 More IKE encryption algorithms will come after porting libcrypto into
143 - initial support for rekeying CHILD_SAs using IKEv2. Currently no
144 perfect forward secrecy is used. The rekeying parameters rekey,
145 rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported
146 when using IKEv2. WARNING: charon currently is unable to handle
147 simultaneous rekeying. To avoid such a situation, use a large
148 rekeyfuzz, or even better, set rekey=no on one peer.
150 - support for host2host, net2net, host2net (roadwarrior) tunnels
151 using predefined RSA certificates (see uml scenarios for
152 configuration examples).
154 - new build environment featuring autotools. Features such
155 as HTTP, LDAP and smartcard support may be enabled using
156 the ./configure script. Changing install directories
157 is possible, too. See ./configure --help for more details.
159 - better integration of charon with ipsec starter, which allows
160 (almost) transparent operation with both daemons. charon
161 handles ipsec commands up, down, status, statusall, listall,
162 listcerts and allows proper load, reload and delete of connections
169 - initial support of the IKEv2 protocol. Connections in
170 ipsec.conf designated by keyexchange=ikev2 are negotiated
171 by the new IKEv2 charon keying daemon whereas those marked
172 by keyexchange=ikev1 or the default keyexchange=ike are
173 handled thy the IKEv1 pluto keying daemon. Currently only
174 a limited subset of functions are available with IKEv2
175 (Default AES encryption, authentication based on locally
176 imported X.509 certificates, unencrypted private RSA keys
177 in PKCS#1 file format, limited functionality of the ipsec
184 - the dynamic iptables rules from the _updown_x509 template
185 for KLIPS and the _updown_policy template for NETKEY have
186 been merged into the default _updown script. The existing
187 left|rightfirewall keyword causes the automatic insertion
188 and deletion of ACCEPT rules for tunneled traffic upon
189 the successful setup and teardown of an IPsec SA, respectively.
190 left|rightfirwall can be used with KLIPS under any Linux 2.4
191 kernel or with NETKEY under a Linux kernel version >= 2.6.16
192 in conjuction with iptables >= 1.3.5. For NETKEY under a Linux
193 kernel version < 2.6.16 which does not support IPsec policy
194 matching yet, please continue to use a copy of the _updown_espmark
195 template loaded via the left|rightupdown keyword.
197 - a new left|righthostaccess keyword has been introduced which
198 can be used in conjunction with left|rightfirewall and the
199 default _updown script. By default leftfirewall=yes inserts
200 a bi-directional iptables FORWARD rule for a local client network
201 with a netmask different from 255.255.255.255 (single host).
202 This does not allow to access the VPN gateway host via its
203 internal network interface which is part of the client subnet
204 because an iptables INPUT and OUTPUT rule would be required.
205 lefthostaccess=yes will cause this additional ACCEPT rules to
208 - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal
209 payload is preparsed in order to find out whether the roadwarrior
210 requests PSK or RSA so that a matching connection candidate can
217 - the new _updown_policy template allows ipsec policy based
218 iptables firewall rules. Required are iptables version
219 >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes
220 the _updown_espmark template, so that no INPUT mangle rules
221 are required any more.
223 - added support of DPD restart mode
225 - ipsec starter now allows the use of wildcards in include
226 statements as e.g. in "include /etc/my_ipsec/*.conf".
227 Patch courtesy of Matthias Haas.
229 - the Netscape OID 'employeeNumber' is now recognized and can be
230 used as a Relative Distinguished Name in certificates.
236 - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec
237 command and not of ipsec setup any more.
239 - ipsec starter now supports AH authentication in conjunction with
240 ESP encryption. AH authentication is configured in ipsec.conf
241 via the auth=ah parameter.
243 - The command ipsec scencrypt|scdecrypt <args> is now an alias for
244 ipsec whack --scencrypt|scdecrypt <args>.
246 - get_sa_info() now determines for the native netkey IPsec stack
247 the exact time of the last use of an active eroute. This information
248 is used by the Dead Peer Detection algorithm and is also displayed by
249 the ipsec status command.
255 - running under the native Linux 2.6 IPsec stack, the function
256 get_sa_info() is called by ipsec auto --status to display the current
257 number of transmitted bytes per IPsec SA.
259 - get_sa_info() is also used by the Dead Peer Detection process to detect
260 recent ESP activity. If ESP traffic was received from the peer within
261 the last dpd_delay interval then no R_Y_THERE notification must be sent.
263 - strongSwan now supports the Relative Distinguished Name "unstructuredName"
264 in ID_DER_ASN1_DN identities. The following notations are possible:
266 rightid="unstructuredName=John Doe"
267 rightid="UN=John Doe"
269 - fixed a long-standing bug which caused PSK-based roadwarrior connections
270 to segfault in the function id.c:same_id() called by keys.c:get_secret()
271 if an FQDN, USER_FQDN, or Key ID was defined, as in the following example.
278 - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall).
280 - ipsec starter didn't set host_addr and client.addr ports in whack msg.
282 - in order to guarantee backwards-compatibility with the script-based
283 auto function (e.g. auto --replace), the ipsec starter scripts stores
284 the defaultroute information in the temporary file /var/run/ipsec.info.
286 - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH
287 Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config
290 - the ipsec starter now also recognizes the parameters authby=never and
291 type=passthrough|pass|drop|reject.
297 - ipsec starter now supports the also parameter which allows
298 a modular structure of the connection definitions. Thus
299 "ipsec start" is now ready to replace "ipsec setup".
305 - Mathieu Lafon's popular ipsec starter tool has been added to the
306 strongSwan distribution. Many thanks go to Stephan Scholz from astaro
307 for his integration work. ipsec starter is a C program which is going
308 to replace the various shell and awk starter scripts (setup, _plutoload,
309 _plutostart, _realsetup, _startklips, _confread, and auto). Since
310 ipsec.conf is now parsed only once, the starting of multiple tunnels is
311 accelerated tremedously.
313 - Added support of %defaultroute to the ipsec starter. If the IP address
314 changes, a HUP signal to the ipsec starter will automatically
315 reload pluto's connections.
317 - moved most compile time configurations from pluto/Makefile to
318 Makefile.inc by defining the options USE_LIBCURL, USE_LDAP,
319 USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE.
321 - removed the ipsec verify and ipsec newhostkey commands
323 - fixed some 64-bit issues in formatted print statements
325 - The scepclient functionality implementing the Simple Certificate
326 Enrollment Protocol (SCEP) is nearly complete but hasn't been
333 - CA certicates are now automatically loaded from a smartcard
334 or USB crypto token and appear in the ipsec auto --listcacerts
341 - when using "ipsec whack --scencrypt <data>" with a PKCS#11
342 library that does not support the C_Encrypt() Cryptoki
343 function (e.g. OpenSC), the RSA encryption is done in
344 software using the public key fetched from the smartcard.
346 - The scepclient function now allows to define the
347 validity of a self-signed certificate using the --days,
348 --startdate, and --enddate options. The default validity
349 has been changed from one year to five years.
355 - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11
356 interface to other applications for RSA encryption and decryption
357 via the whack interface. Notation:
359 ipsec whack --scencrypt <data>
360 [--inbase 16|hex|64|base64|256|text|ascii]
361 [--outbase 16|hex|64|base64|256|text|ascii]
364 ipsec whack --scdecrypt <data>
365 [--inbase 16|hex|64|base64|256|text|ascii]
366 [--outbase 16|hex|64|base64|256|text|ascii]
369 The default setting for inbase and outbase is hex.
371 The new proxy interface can be used for securing symmetric
372 encryption keys required by the cryptoloop or dm-crypt
373 disk encryption schemes, especially in the case when
374 pkcs11keepstate=yes causes pluto to lock the pkcs11 slot
377 - if the file /etc/ipsec.secrets is lacking during the startup of
378 pluto then the root-readable file /etc/ipsec.d/private/myKey.der
379 containing a 2048 bit RSA private key and a matching self-signed
380 certificate stored in the file /etc/ipsec.d/certs/selfCert.der
381 is automatically generated by calling the function
383 ipsec scepclient --out pkcs1 --out cert-self
385 scepclient was written by Jan Hutter and Martin Willi, students
386 at the University of Applied Sciences in Rapperswil, Switzerland.
392 - the current extension of the PKCS#7 framework introduced
393 a parsing error in PKCS#7 wrapped X.509 certificates that are
394 e.g. transmitted by Windows XP when multi-level CAs are used.
395 the parsing syntax has been fixed.
397 - added a patch by Gerald Richter which tolerates multiple occurrences
398 of the ipsec0 interface when using KLIPS.
404 - with gawk-3.1.4 the word "default2 has become a protected
405 keyword for use in switch statements and cannot be used any
406 more in the strongSwan scripts. This problem has been
407 solved by renaming "default" to "defaults" and "setdefault"
408 in the scripts _confread and auto, respectively.
410 - introduced the parameter leftsendcert with the values
412 always|yes (the default, always send a cert)
413 ifasked (send the cert only upon a cert request)
414 never|no (never send a cert, used for raw RSA keys and
417 - fixed the initialization of the ESP key length to a default of
418 128 bits in the case that the peer does not send a key length
419 attribute for AES encryption.
421 - applied Herbert Xu's uniqueIDs patch
423 - applied Herbert Xu's CLOEXEC patches
429 - CRLs can now be cached also in the case when the issuer's
430 certificate does not contain a subjectKeyIdentifier field.
431 In that case the subjectKeyIdentifier is computed by pluto as the
432 160 bit SHA-1 hash of the issuer's public key in compliance
433 with section 4.2.1.2 of RFC 3280.
435 - Fixed a bug introduced by strongswan-2.5.1 which eliminated
436 not only multiple Quick Modes of a given connection but also
437 multiple connections between two security gateways.
443 - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute
444 installed either by setting auto=route in ipsec.conf or by
445 a connection put into hold, generates an XFRM_AQUIRE event
446 for each packet that wants to use the not-yet exisiting
447 tunnel. Up to now each XFRM_AQUIRE event led to an entry in
448 the Quick Mode queue, causing multiple IPsec SA to be
449 established in rapid succession. Starting with strongswan-2.5.1
450 only a single IPsec SA is established per host-pair connection.
452 - Right after loading the PKCS#11 module, all smartcard slots are
453 searched for certificates. The result can be viewed using
456 ipsec auto --listcards
458 The certificate objects found in the slots are numbered
459 starting with #1, #2, etc. This position number can be used to address
460 certificates (leftcert=%smartcard) and keys (: PIN %smartcard)
461 in ipsec.conf and ipsec.secrets, respectively:
463 %smartcard (selects object #1)
464 %smartcard#1 (selects object #1)
465 %smartcard#3 (selects object #3)
467 As an alternative the existing retrieval scheme can be used:
469 %smartcard:45 (selects object with id=45)
470 %smartcard0 (selects first object in slot 0)
471 %smartcard4:45 (selects object in slot 4 with id=45)
473 - Depending on the settings of CKA_SIGN and CKA_DECRYPT
474 private key flags either C_Sign() or C_Decrypt() is used
475 to generate a signature.
477 - The output buffer length parameter siglen in C_Sign()
478 is now initialized to the actual size of the output
479 buffer prior to the function call. This fixes the
480 CKR_BUFFER_TOO_SMALL error that could occur when using
481 the OpenSC PKCS#11 module.
483 - Changed the initialization of the PKCS#11 CK_MECHANISM in
484 C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }.
486 - Refactored the RSA public/private key code and transferred it
487 from keys.c to the new pkcs1.c file as a preparatory step
488 towards the release of the SCEP client.
494 - The loading of a PKCS#11 smartcard library module during
495 runtime does not require OpenSC library functions any more
496 because the corresponding code has been integrated into
497 smartcard.c. Also the RSAREF pkcs11 header files have been
498 included in a newly created pluto/rsaref directory so that
499 no external include path has to be defined any longer.
501 - A long-awaited feature has been implemented at last:
502 The local caching of CRLs fetched via HTTP or LDAP, activated
503 by the parameter cachecrls=yes in the config setup section
504 of ipsec.conf. The dynamically fetched CRLs are stored under
505 a unique file name containing the issuer's subjectKeyID
506 in /etc/ipsec.d/crls.
508 - Applied a one-line patch courtesy of Michael Richardson
509 from the Openswan project which fixes the kernel-oops
510 in KLIPS when an snmp daemon is running on the same box.
516 - Eliminated null length CRL distribution point strings.
518 - Fixed a trust path evaluation bug introduced with 2.4.3
524 - Improved the joint OCSP / CRL revocation policy.
525 OCSP responses have precedence over CRL entries.
527 - Introduced support of CRLv2 reason codes.
529 - Fixed a bug with key-pad equipped readers which caused
530 pluto to prompt for the pin via the console when the first
531 occasion to enter the pin via the key-pad was missed.
533 - When pluto is built with LDAP_V3 enabled, the library
534 liblber required by newer versions of openldap is now
541 - Added the _updown_espmark template which requires all
542 incoming ESP traffic to be marked with a default mark
545 - Introduced the pkcs11keepstate parameter in the config setup
546 section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11
547 session and login states are kept as long as possible during
548 the lifetime of pluto. This means that a PIN entry via a key
549 pad has to be done only once.
551 - Introduced the pkcs11module parameter in the config setup
552 section of ipsec.conf which specifies the PKCS#11 module
553 to be used with smart cards. Example:
555 pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo
557 - Added support of smartcard readers equipped with a PIN pad.
559 - Added patch by Jay Pfeifer which detects when netkey
560 modules have been statically built into the Linux 2.6 kernel.
562 - Added two patches by Herbert Xu. The first uses ip xfrm
563 instead of setkey to flush the IPsec policy database. The
564 second sets the optional flag in inbound IPComp SAs only.
566 - Applied Ulrich Weber's patch which fixes an interoperability
567 problem between native IPsec and KLIPS systems caused by
568 setting the replay window to 32 instead of 0 for ipcomp.
574 - Fixed a bug which caused an unwanted Mode Config request
575 to be initiated in the case where "right" was used to denote
576 the local side in ipsec.conf and "left" the remote side,
577 contrary to the recommendation that "right" be remote and
584 - updated Vendor ID to strongSwan-2.4.0
586 - updated copyright statement to include David Buechi and
593 - strongSwan now communicates with attached smartcards and
594 USB crypto tokens via the standardized PKCS #11 interface.
595 By default the OpenSC library from www.opensc.org is used
596 but any other PKCS#11 library could be dynamically linked.
597 strongSwan's PKCS#11 API was implemented by David Buechi
598 and Michael Meier, both graduates of the Zurich University
599 of Applied Sciences in Winterthur, Switzerland.
601 - When a %trap eroute is triggered by an outgoing IP packet
602 then the native IPsec stack of the Linux 2.6 kernel [often/
603 always?] returns an XFRM_ACQUIRE message with an undefined
604 protocol family field and the connection setup fails.
605 As a workaround IPv4 (AF_INET) is now assumed.
607 - the results of the UML test scenarios are now enhanced
608 with block diagrams of the virtual network topology used
609 in a particular test.
615 - fixed IV used to decrypt informational messages.
616 This bug was introduced with Mode Config functionality.
618 - fixed NCP Vendor ID.
620 - undid one of Ulrich Weber's maximum udp size patches
621 because it caused a segmentation fault with NAT-ed
624 - added UML scenarios wildcards and attr-cert which
625 demonstrate the implementation of IPsec policies based
626 on wildcard parameters contained in Distinguished Names and
627 on X.509 attribute certificates, respectively.
633 - Added basic Mode Config functionality
635 - Added Mathieu Lafon's patch which upgrades the status of
636 the NAT-Traversal implementation to RFC 3947.
638 - The _startklips script now also loads the xfrm4_tunnel
641 - Added Ulrich Weber's netlink replay window size and
642 maximum udp size patches.
644 - UML testing now uses the Linux 2.6.10 UML kernel by default.
650 - Eric Marchionni and Patrik Rayo, both recent graduates from
651 the Zuercher Hochschule Winterthur in Switzerland, created a
652 User-Mode-Linux test setup for strongSwan. For more details
653 please read the INSTALL and README documents in the testing
656 - Full support of group attributes based on X.509 attribute
657 certificates. Attribute certificates can be generated
658 using the openac facility. For more details see
662 The group attributes can be used in connection definitions
663 in order to give IPsec access to specific user groups.
664 This is done with the new parameter left|rightgroups as in
666 rightgroups="Research, Sales"
668 giving access to users possessing the group attributes
669 Research or Sales, only.
671 - In Quick Mode clients with subnet mask /32 are now
672 coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should
673 fix rekeying problems with the SafeNet/SoftRemote and NCP
674 Secure Entry Clients.
676 - Changed the defaults of the ikelifetime and keylife parameters
677 to 3h and 1h, respectively. The maximum allowable values are
678 now both set to 24 h.
680 - Suppressed notification wars between two IPsec peers that
681 could e.g. be triggered by incorrect ISAKMP encryption.
683 - Public RSA keys can now have identical IDs if either the
684 issuing CA or the serial number is different. The serial
685 number of a certificate is now shown by the command
687 ipsec auto --listpubkeys
693 - Added Tuomo Soini's sourceip feature which allows a strongSwan
694 roadwarrior to use a fixed Virtual IP (see README section 2.6)
695 and reduces the well-known four tunnel case on VPN gateways to
696 a single tunnel definition (see README section 2.4).
698 - Fixed a bug occuring with NAT-Traversal enabled when the responder
699 suddenly turns initiator and the initiator cannot find a matching
700 connection because of the floated IKE port 4500.
702 - Removed misleading ipsec verify command from barf.
704 - Running under the native IP stack, ipsec --version now shows
705 the Linux kernel version (courtesy to the Openswan project).
711 - Introduced the ipsec auto --listalgs monitoring command which lists
712 all currently registered IKE and ESP algorithms.
714 - Fixed a bug in the ESP algorithm selection occuring when the strict flag
715 is set and the first proposed transform does not match.
717 - Fixed another deadlock in the use of the lock_certs_and_keys() mutex,
718 occuring when a smartcard is present.
720 - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event.
722 - Fixed the printing of the notification names (null)
724 - Applied another of Herbert Xu's Netlink patches.
730 - Support of Dead Peer Detection. The connection parameter
734 activates DPD for the given connection.
736 - The default Opportunistic Encryption (OE) policy groups are not
737 automatically included anymore. Those wishing to activate OE can include
738 the policy group with the following statement in ipsec.conf:
740 include /etc/ipsec.d/examples/oe.conf
742 The default for [right|left]rsasigkey is now set to %cert.
744 - strongSwan now has a Vendor ID of its own which can be activated
745 using the compile option VENDORID
747 - Applied Herbert Xu's patch which sets the compression algorithm correctly.
749 - Applied Herbert Xu's patch fixing an ESPINUDP problem
751 - Applied Herbert Xu's patch setting source/destination port numbers.
753 - Reapplied one of Herbert Xu's NAT-Traversal patches which got
754 lost during the migration from SuperFreeS/WAN.
756 - Fixed a deadlock in the use of the lock_certs_and_keys() mutex.
758 - Fixed the unsharing of alg parameters when instantiating group
765 - Thomas Walpuski made me aware of a potential DoS attack via
766 a PKCS#7-wrapped certificate bundle which could overwrite valid CA
767 certificates in Pluto's authority certificate store. This vulnerability
768 was fixed by establishing trust in CA candidate certificates up to a
769 trusted root CA prior to insertion into Pluto's chained list.
771 - replaced the --assign option by the -v option in the auto awk script
772 in order to make it run with mawk under debian/woody.
778 - Split of the status information between ipsec auto --status (concise)
779 and ipsec auto --statusall (verbose). Both commands can be used with
780 an optional connection selector:
782 ipsec auto --status[all] <connection_name>
784 - Added the description of X.509 related features to the ipsec_auto(8)
787 - Hardened the ASN.1 parser in debug mode, especially the printing
788 of malformed distinguished names.
790 - The size of an RSA public key received in a certificate is now restricted to
792 512 bits <= modulus length <= 8192 bits.
794 - Fixed the debug mode enumeration.
800 - Fixed another PKCS#7 vulnerability which could lead to an
801 endless loop while following the X.509 trust chain.
807 - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski
808 that accepted end certificates having identical issuer and subject
809 distinguished names in a multi-tier X.509 trust chain.
815 - Removed all remaining references to ipsec_netlink.h in KLIPS.
821 - The new "ca" section allows to define the following parameters:
824 cacert=koolCA.pem # cacert of kool CA
825 ocspuri=http://ocsp.kool.net:8001 # ocsp server
826 ldapserver=ldap.kool.net # default ldap server
827 crluri=http://www.kool.net/kool.crl # crl distribution point
828 crluri2="ldap:///O=Kool, C= .." # crl distribution point #2
829 auto=add # add, ignore
831 The ca definitions can be monitored via the command
833 ipsec auto --listcainfos
835 - Fixed cosmetic corruption of /proc filesystem by integrating
836 D. Hugh Redelmeier's freeswan-2.06 kernel fixes.
842 - Added support for the 818043 NAT-Traversal update of Microsoft's
843 Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode.
845 - A symbolic link to libcrypto is now added in the kernel sources
846 during kernel compilation
848 - Fixed a couple of 64 bit issues (mostly casts to int).
849 Thanks to Ken Bantoft who checked my sources on a 64 bit platform.
851 - Replaced s[n]printf() statements in the kernel by ipsec_snprintf().
852 Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro
853 of the FreeS/WAN team who solved this problem with the 2.4.25 kernel.
859 - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName
860 certificate extension which contains no generalName item) can cause
861 a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has
862 been hardened to make it more robust against malformed ASN.1 objects.
864 - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native
865 Linux 2.6 IPsec stack.
871 - based on freeswan-2.04, x509-1.5.3, nat-0.6c, alg-0.8.1rc12
