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].
16 - strongSwan now interoperates with the NCP Secure Entry Client,
17 the Shrew Soft VPN Client, and the Cisco VPN client, doing both
18 XAUTH and Mode Config.
20 - UNITY attributes are now recognized and UNITY_BANNER is set
27 - IKEv1: Support for extended authentication (XAUTH) in combination
28 with ISAKMP Main Mode RSA or PSK authentication. Both client and
29 server side were implemented. Handling of user credentials can
30 be done by a run-time loadable XAUTH module. By default user
31 credentials are stored in ipsec.secrets.
33 - IKEv2: Support for reauthentication when rekeying
35 - IKEv2: Support for transport mode
37 - fixed a lot of bugs related to byte order
39 - various other bugfixes
45 - IKEv1: Implementation of ModeConfig push mode via the new connection
46 keyword modeconfig=push allows interoperability with Cisco VPN gateways.
48 - IKEv1: The command ipsec statusall now shows "DPD active" for all
49 ISAKMP SAs that are under active Dead Peer Detection control.
51 - IKEv2: Charon's logging and debugging framework has been completely rewritten.
52 Instead of logger, special printf() functions are used to directly
53 print objects like hosts (%H) identifications (%D), certificates (%Q),
54 etc. The number of debugging levels have been reduced to:
56 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private)
58 The debugging levels can either be specified statically in ipsec.conf as
61 charondebug="lib 1, cfg 3, net 2"
63 or changed at runtime via stroke as
65 ipsec stroke loglevel cfg 2
71 - Implemented full support for IPv6-in-IPv6 tunnels.
73 - Added configuration options for dead peer detection in IKEv2. dpd_action
74 types "clear", "hold" and "restart" are supported. The dpd_timeout
75 value is not used, as the normal retransmission policy applies to
76 detect dead peers. The dpd_delay parameter enables sending of empty
77 informational message to detect dead peers in case of inactivity.
79 - Added support for preshared keys in IKEv2. PSK keys configured in
80 ipsec.secrets are loaded. The authby parameter specifies the authentication
81 method to authentificate ourself, the other peer may use PSK or RSA.
83 - Changed retransmission policy to respect the keyingtries parameter.
85 - Added private key decryption. PEM keys encrypted with AES-128/192/256
86 or 3DES are supported.
88 - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to
91 - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates
92 signed with such a hash algorithm.
94 - Added initial support for updown scripts. The actions up-host/client and
95 down-host/client are executed. The leftfirewall=yes parameter
96 uses the default updown script to insert dynamic firewall rules, a custom
97 updown script may be specified with the leftupdown parameter.
103 - Added support for the auto=route ipsec.conf parameter and the
104 ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and
105 CHILD_SAs dynamically on demand when traffic is detected by the
108 - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter.
109 As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only
110 new keys are generated using perfect forward secrecy. An optional flag
111 which enforces reauthentication will be implemented later.
113 - "sha" and "sha1" are now treated as synonyms in the ike= and esp=
114 algorithm configuration statements.
120 - Full X.509 certificate trust chain verification has been implemented.
121 End entity certificates can be exchanged via CERT payloads. The current
122 default is leftsendcert=always, since CERTREQ payloads are not supported
123 yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls.
125 - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2
126 would offer more possibilities for traffic selection, but the Linux kernel
127 currently does not support it. That's why we stick with these simple
128 ipsec.conf rules for now.
130 - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no
131 IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear,
134 - Initial NAT traversal support in IKEv2. Charon includes NAT detection
135 notify payloads to detect NAT routers between the peers. It switches
136 to port 4500, uses UDP encapsulated ESP packets, handles peer address
137 changes gracefully and sends keep alive message periodically.
139 - Reimplemented IKE_SA state machine for charon, which allows simultaneous
140 rekeying, more shared code, cleaner design, proper retransmission
141 and a more extensible code base.
143 - The mixed PSK/RSA roadwarrior detection capability introduced by the
144 strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal
145 payloads by the responder right before any defined IKE Main Mode state had
146 been established. Although any form of bad proposal syntax was being correctly
147 detected by the payload parser, the subsequent error handler didn't check
148 the state pointer before logging current state information, causing an
149 immediate crash of the pluto keying daemon due to a NULL pointer.
155 - Added algorithm selection to charon: New default algorithms for
156 ike=aes128-sha-modp2048, as both daemons support it. The default
157 for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles
158 the ike/esp parameter the same way as pluto. As this syntax does
159 not allow specification of a pseudo random function, the same
160 algorithm as for integrity is used (currently sha/md5). Supported
162 Encryption: aes128, aes192, aes256
163 Integrity/PRF: md5, sha (using hmac)
164 DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192
166 Encryption: aes128, aes192, aes256, 3des, blowfish128,
167 blowfish192, blowfish256
169 More IKE encryption algorithms will come after porting libcrypto into
172 - initial support for rekeying CHILD_SAs using IKEv2. Currently no
173 perfect forward secrecy is used. The rekeying parameters rekey,
174 rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported
175 when using IKEv2. WARNING: charon currently is unable to handle
176 simultaneous rekeying. To avoid such a situation, use a large
177 rekeyfuzz, or even better, set rekey=no on one peer.
179 - support for host2host, net2net, host2net (roadwarrior) tunnels
180 using predefined RSA certificates (see uml scenarios for
181 configuration examples).
183 - new build environment featuring autotools. Features such
184 as HTTP, LDAP and smartcard support may be enabled using
185 the ./configure script. Changing install directories
186 is possible, too. See ./configure --help for more details.
188 - better integration of charon with ipsec starter, which allows
189 (almost) transparent operation with both daemons. charon
190 handles ipsec commands up, down, status, statusall, listall,
191 listcerts and allows proper load, reload and delete of connections
198 - initial support of the IKEv2 protocol. Connections in
199 ipsec.conf designated by keyexchange=ikev2 are negotiated
200 by the new IKEv2 charon keying daemon whereas those marked
201 by keyexchange=ikev1 or the default keyexchange=ike are
202 handled thy the IKEv1 pluto keying daemon. Currently only
203 a limited subset of functions are available with IKEv2
204 (Default AES encryption, authentication based on locally
205 imported X.509 certificates, unencrypted private RSA keys
206 in PKCS#1 file format, limited functionality of the ipsec
213 - the dynamic iptables rules from the _updown_x509 template
214 for KLIPS and the _updown_policy template for NETKEY have
215 been merged into the default _updown script. The existing
216 left|rightfirewall keyword causes the automatic insertion
217 and deletion of ACCEPT rules for tunneled traffic upon
218 the successful setup and teardown of an IPsec SA, respectively.
219 left|rightfirwall can be used with KLIPS under any Linux 2.4
220 kernel or with NETKEY under a Linux kernel version >= 2.6.16
221 in conjuction with iptables >= 1.3.5. For NETKEY under a Linux
222 kernel version < 2.6.16 which does not support IPsec policy
223 matching yet, please continue to use a copy of the _updown_espmark
224 template loaded via the left|rightupdown keyword.
226 - a new left|righthostaccess keyword has been introduced which
227 can be used in conjunction with left|rightfirewall and the
228 default _updown script. By default leftfirewall=yes inserts
229 a bi-directional iptables FORWARD rule for a local client network
230 with a netmask different from 255.255.255.255 (single host).
231 This does not allow to access the VPN gateway host via its
232 internal network interface which is part of the client subnet
233 because an iptables INPUT and OUTPUT rule would be required.
234 lefthostaccess=yes will cause this additional ACCEPT rules to
237 - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal
238 payload is preparsed in order to find out whether the roadwarrior
239 requests PSK or RSA so that a matching connection candidate can
246 - the new _updown_policy template allows ipsec policy based
247 iptables firewall rules. Required are iptables version
248 >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes
249 the _updown_espmark template, so that no INPUT mangle rules
250 are required any more.
252 - added support of DPD restart mode
254 - ipsec starter now allows the use of wildcards in include
255 statements as e.g. in "include /etc/my_ipsec/*.conf".
256 Patch courtesy of Matthias Haas.
258 - the Netscape OID 'employeeNumber' is now recognized and can be
259 used as a Relative Distinguished Name in certificates.
265 - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec
266 command and not of ipsec setup any more.
268 - ipsec starter now supports AH authentication in conjunction with
269 ESP encryption. AH authentication is configured in ipsec.conf
270 via the auth=ah parameter.
272 - The command ipsec scencrypt|scdecrypt <args> is now an alias for
273 ipsec whack --scencrypt|scdecrypt <args>.
275 - get_sa_info() now determines for the native netkey IPsec stack
276 the exact time of the last use of an active eroute. This information
277 is used by the Dead Peer Detection algorithm and is also displayed by
278 the ipsec status command.
284 - running under the native Linux 2.6 IPsec stack, the function
285 get_sa_info() is called by ipsec auto --status to display the current
286 number of transmitted bytes per IPsec SA.
288 - get_sa_info() is also used by the Dead Peer Detection process to detect
289 recent ESP activity. If ESP traffic was received from the peer within
290 the last dpd_delay interval then no R_Y_THERE notification must be sent.
292 - strongSwan now supports the Relative Distinguished Name "unstructuredName"
293 in ID_DER_ASN1_DN identities. The following notations are possible:
295 rightid="unstructuredName=John Doe"
296 rightid="UN=John Doe"
298 - fixed a long-standing bug which caused PSK-based roadwarrior connections
299 to segfault in the function id.c:same_id() called by keys.c:get_secret()
300 if an FQDN, USER_FQDN, or Key ID was defined, as in the following example.
307 - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall).
309 - ipsec starter didn't set host_addr and client.addr ports in whack msg.
311 - in order to guarantee backwards-compatibility with the script-based
312 auto function (e.g. auto --replace), the ipsec starter scripts stores
313 the defaultroute information in the temporary file /var/run/ipsec.info.
315 - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH
316 Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config
319 - the ipsec starter now also recognizes the parameters authby=never and
320 type=passthrough|pass|drop|reject.
326 - ipsec starter now supports the also parameter which allows
327 a modular structure of the connection definitions. Thus
328 "ipsec start" is now ready to replace "ipsec setup".
334 - Mathieu Lafon's popular ipsec starter tool has been added to the
335 strongSwan distribution. Many thanks go to Stephan Scholz from astaro
336 for his integration work. ipsec starter is a C program which is going
337 to replace the various shell and awk starter scripts (setup, _plutoload,
338 _plutostart, _realsetup, _startklips, _confread, and auto). Since
339 ipsec.conf is now parsed only once, the starting of multiple tunnels is
340 accelerated tremedously.
342 - Added support of %defaultroute to the ipsec starter. If the IP address
343 changes, a HUP signal to the ipsec starter will automatically
344 reload pluto's connections.
346 - moved most compile time configurations from pluto/Makefile to
347 Makefile.inc by defining the options USE_LIBCURL, USE_LDAP,
348 USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE.
350 - removed the ipsec verify and ipsec newhostkey commands
352 - fixed some 64-bit issues in formatted print statements
354 - The scepclient functionality implementing the Simple Certificate
355 Enrollment Protocol (SCEP) is nearly complete but hasn't been
362 - CA certicates are now automatically loaded from a smartcard
363 or USB crypto token and appear in the ipsec auto --listcacerts
370 - when using "ipsec whack --scencrypt <data>" with a PKCS#11
371 library that does not support the C_Encrypt() Cryptoki
372 function (e.g. OpenSC), the RSA encryption is done in
373 software using the public key fetched from the smartcard.
375 - The scepclient function now allows to define the
376 validity of a self-signed certificate using the --days,
377 --startdate, and --enddate options. The default validity
378 has been changed from one year to five years.
384 - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11
385 interface to other applications for RSA encryption and decryption
386 via the whack interface. Notation:
388 ipsec whack --scencrypt <data>
389 [--inbase 16|hex|64|base64|256|text|ascii]
390 [--outbase 16|hex|64|base64|256|text|ascii]
393 ipsec whack --scdecrypt <data>
394 [--inbase 16|hex|64|base64|256|text|ascii]
395 [--outbase 16|hex|64|base64|256|text|ascii]
398 The default setting for inbase and outbase is hex.
400 The new proxy interface can be used for securing symmetric
401 encryption keys required by the cryptoloop or dm-crypt
402 disk encryption schemes, especially in the case when
403 pkcs11keepstate=yes causes pluto to lock the pkcs11 slot
406 - if the file /etc/ipsec.secrets is lacking during the startup of
407 pluto then the root-readable file /etc/ipsec.d/private/myKey.der
408 containing a 2048 bit RSA private key and a matching self-signed
409 certificate stored in the file /etc/ipsec.d/certs/selfCert.der
410 is automatically generated by calling the function
412 ipsec scepclient --out pkcs1 --out cert-self
414 scepclient was written by Jan Hutter and Martin Willi, students
415 at the University of Applied Sciences in Rapperswil, Switzerland.
421 - the current extension of the PKCS#7 framework introduced
422 a parsing error in PKCS#7 wrapped X.509 certificates that are
423 e.g. transmitted by Windows XP when multi-level CAs are used.
424 the parsing syntax has been fixed.
426 - added a patch by Gerald Richter which tolerates multiple occurrences
427 of the ipsec0 interface when using KLIPS.
433 - with gawk-3.1.4 the word "default2 has become a protected
434 keyword for use in switch statements and cannot be used any
435 more in the strongSwan scripts. This problem has been
436 solved by renaming "default" to "defaults" and "setdefault"
437 in the scripts _confread and auto, respectively.
439 - introduced the parameter leftsendcert with the values
441 always|yes (the default, always send a cert)
442 ifasked (send the cert only upon a cert request)
443 never|no (never send a cert, used for raw RSA keys and
446 - fixed the initialization of the ESP key length to a default of
447 128 bits in the case that the peer does not send a key length
448 attribute for AES encryption.
450 - applied Herbert Xu's uniqueIDs patch
452 - applied Herbert Xu's CLOEXEC patches
458 - CRLs can now be cached also in the case when the issuer's
459 certificate does not contain a subjectKeyIdentifier field.
460 In that case the subjectKeyIdentifier is computed by pluto as the
461 160 bit SHA-1 hash of the issuer's public key in compliance
462 with section 4.2.1.2 of RFC 3280.
464 - Fixed a bug introduced by strongswan-2.5.1 which eliminated
465 not only multiple Quick Modes of a given connection but also
466 multiple connections between two security gateways.
472 - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute
473 installed either by setting auto=route in ipsec.conf or by
474 a connection put into hold, generates an XFRM_AQUIRE event
475 for each packet that wants to use the not-yet exisiting
476 tunnel. Up to now each XFRM_AQUIRE event led to an entry in
477 the Quick Mode queue, causing multiple IPsec SA to be
478 established in rapid succession. Starting with strongswan-2.5.1
479 only a single IPsec SA is established per host-pair connection.
481 - Right after loading the PKCS#11 module, all smartcard slots are
482 searched for certificates. The result can be viewed using
485 ipsec auto --listcards
487 The certificate objects found in the slots are numbered
488 starting with #1, #2, etc. This position number can be used to address
489 certificates (leftcert=%smartcard) and keys (: PIN %smartcard)
490 in ipsec.conf and ipsec.secrets, respectively:
492 %smartcard (selects object #1)
493 %smartcard#1 (selects object #1)
494 %smartcard#3 (selects object #3)
496 As an alternative the existing retrieval scheme can be used:
498 %smartcard:45 (selects object with id=45)
499 %smartcard0 (selects first object in slot 0)
500 %smartcard4:45 (selects object in slot 4 with id=45)
502 - Depending on the settings of CKA_SIGN and CKA_DECRYPT
503 private key flags either C_Sign() or C_Decrypt() is used
504 to generate a signature.
506 - The output buffer length parameter siglen in C_Sign()
507 is now initialized to the actual size of the output
508 buffer prior to the function call. This fixes the
509 CKR_BUFFER_TOO_SMALL error that could occur when using
510 the OpenSC PKCS#11 module.
512 - Changed the initialization of the PKCS#11 CK_MECHANISM in
513 C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }.
515 - Refactored the RSA public/private key code and transferred it
516 from keys.c to the new pkcs1.c file as a preparatory step
517 towards the release of the SCEP client.
523 - The loading of a PKCS#11 smartcard library module during
524 runtime does not require OpenSC library functions any more
525 because the corresponding code has been integrated into
526 smartcard.c. Also the RSAREF pkcs11 header files have been
527 included in a newly created pluto/rsaref directory so that
528 no external include path has to be defined any longer.
530 - A long-awaited feature has been implemented at last:
531 The local caching of CRLs fetched via HTTP or LDAP, activated
532 by the parameter cachecrls=yes in the config setup section
533 of ipsec.conf. The dynamically fetched CRLs are stored under
534 a unique file name containing the issuer's subjectKeyID
535 in /etc/ipsec.d/crls.
537 - Applied a one-line patch courtesy of Michael Richardson
538 from the Openswan project which fixes the kernel-oops
539 in KLIPS when an snmp daemon is running on the same box.
545 - Eliminated null length CRL distribution point strings.
547 - Fixed a trust path evaluation bug introduced with 2.4.3
553 - Improved the joint OCSP / CRL revocation policy.
554 OCSP responses have precedence over CRL entries.
556 - Introduced support of CRLv2 reason codes.
558 - Fixed a bug with key-pad equipped readers which caused
559 pluto to prompt for the pin via the console when the first
560 occasion to enter the pin via the key-pad was missed.
562 - When pluto is built with LDAP_V3 enabled, the library
563 liblber required by newer versions of openldap is now
570 - Added the _updown_espmark template which requires all
571 incoming ESP traffic to be marked with a default mark
574 - Introduced the pkcs11keepstate parameter in the config setup
575 section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11
576 session and login states are kept as long as possible during
577 the lifetime of pluto. This means that a PIN entry via a key
578 pad has to be done only once.
580 - Introduced the pkcs11module parameter in the config setup
581 section of ipsec.conf which specifies the PKCS#11 module
582 to be used with smart cards. Example:
584 pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo
586 - Added support of smartcard readers equipped with a PIN pad.
588 - Added patch by Jay Pfeifer which detects when netkey
589 modules have been statically built into the Linux 2.6 kernel.
591 - Added two patches by Herbert Xu. The first uses ip xfrm
592 instead of setkey to flush the IPsec policy database. The
593 second sets the optional flag in inbound IPComp SAs only.
595 - Applied Ulrich Weber's patch which fixes an interoperability
596 problem between native IPsec and KLIPS systems caused by
597 setting the replay window to 32 instead of 0 for ipcomp.
603 - Fixed a bug which caused an unwanted Mode Config request
604 to be initiated in the case where "right" was used to denote
605 the local side in ipsec.conf and "left" the remote side,
606 contrary to the recommendation that "right" be remote and
613 - updated Vendor ID to strongSwan-2.4.0
615 - updated copyright statement to include David Buechi and
622 - strongSwan now communicates with attached smartcards and
623 USB crypto tokens via the standardized PKCS #11 interface.
624 By default the OpenSC library from www.opensc.org is used
625 but any other PKCS#11 library could be dynamically linked.
626 strongSwan's PKCS#11 API was implemented by David Buechi
627 and Michael Meier, both graduates of the Zurich University
628 of Applied Sciences in Winterthur, Switzerland.
630 - When a %trap eroute is triggered by an outgoing IP packet
631 then the native IPsec stack of the Linux 2.6 kernel [often/
632 always?] returns an XFRM_ACQUIRE message with an undefined
633 protocol family field and the connection setup fails.
634 As a workaround IPv4 (AF_INET) is now assumed.
636 - the results of the UML test scenarios are now enhanced
637 with block diagrams of the virtual network topology used
638 in a particular test.
644 - fixed IV used to decrypt informational messages.
645 This bug was introduced with Mode Config functionality.
647 - fixed NCP Vendor ID.
649 - undid one of Ulrich Weber's maximum udp size patches
650 because it caused a segmentation fault with NAT-ed
653 - added UML scenarios wildcards and attr-cert which
654 demonstrate the implementation of IPsec policies based
655 on wildcard parameters contained in Distinguished Names and
656 on X.509 attribute certificates, respectively.
662 - Added basic Mode Config functionality
664 - Added Mathieu Lafon's patch which upgrades the status of
665 the NAT-Traversal implementation to RFC 3947.
667 - The _startklips script now also loads the xfrm4_tunnel
670 - Added Ulrich Weber's netlink replay window size and
671 maximum udp size patches.
673 - UML testing now uses the Linux 2.6.10 UML kernel by default.
679 - Eric Marchionni and Patrik Rayo, both recent graduates from
680 the Zuercher Hochschule Winterthur in Switzerland, created a
681 User-Mode-Linux test setup for strongSwan. For more details
682 please read the INSTALL and README documents in the testing
685 - Full support of group attributes based on X.509 attribute
686 certificates. Attribute certificates can be generated
687 using the openac facility. For more details see
691 The group attributes can be used in connection definitions
692 in order to give IPsec access to specific user groups.
693 This is done with the new parameter left|rightgroups as in
695 rightgroups="Research, Sales"
697 giving access to users possessing the group attributes
698 Research or Sales, only.
700 - In Quick Mode clients with subnet mask /32 are now
701 coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should
702 fix rekeying problems with the SafeNet/SoftRemote and NCP
703 Secure Entry Clients.
705 - Changed the defaults of the ikelifetime and keylife parameters
706 to 3h and 1h, respectively. The maximum allowable values are
707 now both set to 24 h.
709 - Suppressed notification wars between two IPsec peers that
710 could e.g. be triggered by incorrect ISAKMP encryption.
712 - Public RSA keys can now have identical IDs if either the
713 issuing CA or the serial number is different. The serial
714 number of a certificate is now shown by the command
716 ipsec auto --listpubkeys
722 - Added Tuomo Soini's sourceip feature which allows a strongSwan
723 roadwarrior to use a fixed Virtual IP (see README section 2.6)
724 and reduces the well-known four tunnel case on VPN gateways to
725 a single tunnel definition (see README section 2.4).
727 - Fixed a bug occuring with NAT-Traversal enabled when the responder
728 suddenly turns initiator and the initiator cannot find a matching
729 connection because of the floated IKE port 4500.
731 - Removed misleading ipsec verify command from barf.
733 - Running under the native IP stack, ipsec --version now shows
734 the Linux kernel version (courtesy to the Openswan project).
740 - Introduced the ipsec auto --listalgs monitoring command which lists
741 all currently registered IKE and ESP algorithms.
743 - Fixed a bug in the ESP algorithm selection occuring when the strict flag
744 is set and the first proposed transform does not match.
746 - Fixed another deadlock in the use of the lock_certs_and_keys() mutex,
747 occuring when a smartcard is present.
749 - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event.
751 - Fixed the printing of the notification names (null)
753 - Applied another of Herbert Xu's Netlink patches.
759 - Support of Dead Peer Detection. The connection parameter
763 activates DPD for the given connection.
765 - The default Opportunistic Encryption (OE) policy groups are not
766 automatically included anymore. Those wishing to activate OE can include
767 the policy group with the following statement in ipsec.conf:
769 include /etc/ipsec.d/examples/oe.conf
771 The default for [right|left]rsasigkey is now set to %cert.
773 - strongSwan now has a Vendor ID of its own which can be activated
774 using the compile option VENDORID
776 - Applied Herbert Xu's patch which sets the compression algorithm correctly.
778 - Applied Herbert Xu's patch fixing an ESPINUDP problem
780 - Applied Herbert Xu's patch setting source/destination port numbers.
782 - Reapplied one of Herbert Xu's NAT-Traversal patches which got
783 lost during the migration from SuperFreeS/WAN.
785 - Fixed a deadlock in the use of the lock_certs_and_keys() mutex.
787 - Fixed the unsharing of alg parameters when instantiating group
794 - Thomas Walpuski made me aware of a potential DoS attack via
795 a PKCS#7-wrapped certificate bundle which could overwrite valid CA
796 certificates in Pluto's authority certificate store. This vulnerability
797 was fixed by establishing trust in CA candidate certificates up to a
798 trusted root CA prior to insertion into Pluto's chained list.
800 - replaced the --assign option by the -v option in the auto awk script
801 in order to make it run with mawk under debian/woody.
807 - Split of the status information between ipsec auto --status (concise)
808 and ipsec auto --statusall (verbose). Both commands can be used with
809 an optional connection selector:
811 ipsec auto --status[all] <connection_name>
813 - Added the description of X.509 related features to the ipsec_auto(8)
816 - Hardened the ASN.1 parser in debug mode, especially the printing
817 of malformed distinguished names.
819 - The size of an RSA public key received in a certificate is now restricted to
821 512 bits <= modulus length <= 8192 bits.
823 - Fixed the debug mode enumeration.
829 - Fixed another PKCS#7 vulnerability which could lead to an
830 endless loop while following the X.509 trust chain.
836 - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski
837 that accepted end certificates having identical issuer and subject
838 distinguished names in a multi-tier X.509 trust chain.
844 - Removed all remaining references to ipsec_netlink.h in KLIPS.
850 - The new "ca" section allows to define the following parameters:
853 cacert=koolCA.pem # cacert of kool CA
854 ocspuri=http://ocsp.kool.net:8001 # ocsp server
855 ldapserver=ldap.kool.net # default ldap server
856 crluri=http://www.kool.net/kool.crl # crl distribution point
857 crluri2="ldap:///O=Kool, C= .." # crl distribution point #2
858 auto=add # add, ignore
860 The ca definitions can be monitored via the command
862 ipsec auto --listcainfos
864 - Fixed cosmetic corruption of /proc filesystem by integrating
865 D. Hugh Redelmeier's freeswan-2.06 kernel fixes.
871 - Added support for the 818043 NAT-Traversal update of Microsoft's
872 Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode.
874 - A symbolic link to libcrypto is now added in the kernel sources
875 during kernel compilation
877 - Fixed a couple of 64 bit issues (mostly casts to int).
878 Thanks to Ken Bantoft who checked my sources on a 64 bit platform.
880 - Replaced s[n]printf() statements in the kernel by ipsec_snprintf().
881 Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro
882 of the FreeS/WAN team who solved this problem with the 2.4.25 kernel.
888 - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName
889 certificate extension which contains no generalName item) can cause
890 a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has
891 been hardened to make it more robust against malformed ASN.1 objects.
893 - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native
894 Linux 2.6 IPsec stack.
900 - based on freeswan-2.04, x509-1.5.3, nat-0.6c, alg-0.8.1rc12
