4 - The pluto IKEv1 daemon now exhibits the same behaviour as its
5 IKEv2 companion charon by inserting an explicit route via the
6 _updown script only if a sourceip exists. This is admissible
7 since routing through the IPsec tunnel is handled automatically
8 by NETKEY's IPsec policies..
14 - IKEv2 peer configuration selection now can be based on a given
15 certification authority using the rightca= statement.
17 - IKEv2 authentication based on RSA signatures now can handle multiple
18 certificates issued for a given peer ID. This allows a smooth transition
19 in the case of a peer certificate renewal.
21 - IKEv2: Support for requesting a specific virtual IP using leftsourceip on the
22 client and returning requested virtual IPs using rightsourceip=%config
23 on the server. If the server does not support configuration payloads, the
24 client enforces its leftsourceip parameter.
26 - The ./configure options --with-uid/--with-gid allow pluto and charon
27 to drop their privileges to a minimum and change to an other UID/GID. This
28 improves the systems security, as a possible intruder may only get the
29 CAP_NET_ADMIN capability.
31 - Further modularization of charon: Pluggable control interface and
32 configuration backend modules provide extensibility. The control interface
33 for stroke is included, and further interfaces using DBUS (NetworkManager)
34 or XML are on the way. A backend for storing configurations in the daemon
35 is provided and more advanced backends (using e.g. a database) are trivial
38 - Fixed a compilation failure in libfreeswan occuring with Linux kernel
45 - Support for an additional Diffie-Hellman exchange when creating/rekeying
46 a CHILD_SA in IKEv2 (PFS). PFS is enabled when the proposal contains a
47 DH group (e.g. "esp=aes128-sha1-modp1536"). Further, DH group negotiation
48 is implemented properly for rekeying.
50 - Support for the AES-XCBC-96 MAC algorithm for IPsec SAs when using IKEv2
51 (requires linux >= 2.6.20). It is enabled using e.g. "esp=aes256-aesxcbc".
53 - Working IPv4-in-IPv6 and IPv6-in-IPv4 tunnels for linux >= 2.6.21.
55 - Added support for EAP modules which do not establish an MSK.
57 - Removed the dependencies from the /usr/include/linux/ headers by
58 including xfrm.h, ipsec.h, and pfkeyv2.h in the distribution.
60 - crlNumber is now listed by ipsec listcrls
62 - The xauth_modules.verify_secret() function now passes the
69 - Server side cookie support. If to may IKE_SAs are in CONNECTING state,
70 cookies are enabled and protect against DoS attacks with faked source
71 addresses. Number of IKE_SAs in CONNECTING state is also limited per
72 peer address to avoid resource exhaustion. IKE_SA_INIT messages are
73 compared to properly detect retransmissions and incoming retransmits are
74 detected even if the IKE_SA is blocked (e.g. doing OCSP fetches).
76 - The IKEv2 daemon charon now supports dynamic http- and ldap-based CRL
77 fetching enabled by crlcheckinterval > 0 and caching fetched CRLs
78 enabled by cachecrls=yes.
80 - Added the configuration options --enable-nat-transport which enables
81 the potentially insecure NAT traversal for IPsec transport mode and
82 --disable-vendor-id which disables the sending of the strongSwan
85 - Fixed a long-standing bug in the pluto IKEv1 daemon which caused
86 a segmentation fault if a malformed payload was detected in the
87 IKE MR2 message and pluto tried to send an encrypted notification
90 - Added the NATT_IETF_02_N Vendor ID in order to support IKEv1 connections
91 with Windows 2003 Server which uses a wrong VID hash.
97 - Support of SHA2_384 hash function for protecting IKEv1
98 negotiations and support of SHA2 signatures in X.509 certificates.
100 - Fixed a serious bug in the computation of the SHA2-512 HMAC
101 function. Introduced automatic self-test of all IKEv1 hash
102 and hmac functions during pluto startup. Failure of a self-test
103 currently issues a warning only but does not exit pluto [yet].
105 - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2.
107 - Full support of CA information sections. ipsec listcainfos
108 now shows all collected crlDistributionPoints and OCSP
111 - Support of the Online Certificate Status Protocol (OCSP) for IKEv2.
112 This feature requires the HTTP fetching capabilities of the libcurl
113 library which must be enabled by setting the --enable-http configure
116 - Refactored core of the IKEv2 message processing code, allowing better
117 code reuse and separation.
119 - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration
120 payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted
121 by the requestor and installed in a resolv.conf file.
123 - The IKEv2 daemon charon installs a route for each IPsec policy to use
124 the correct source address even if an application does not explicitly
127 - Integrated the EAP framework into charon which loads pluggable EAP library
128 modules. The ipsec.conf parameter authby=eap initiates EAP authentication
129 on the client side, while the "eap" parameter on the server side defines
130 the EAP method to use for client authentication.
131 A generic client side EAP-Identity module and an EAP-SIM authentication
132 module using a third party card reader implementation are included.
134 - Added client side support for cookies.
136 - Integrated the fixes done at the IKEv2 interoperability bakeoff, including
137 strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor
138 fixes to enhance interoperability with other implementations.
144 - strongSwan now interoperates with the NCP Secure Entry Client,
145 the Shrew Soft VPN Client, and the Cisco VPN client, doing both
146 XAUTH and Mode Config.
148 - UNITY attributes are now recognized and UNITY_BANNER is set
155 - IKEv1: Support for extended authentication (XAUTH) in combination
156 with ISAKMP Main Mode RSA or PSK authentication. Both client and
157 server side were implemented. Handling of user credentials can
158 be done by a run-time loadable XAUTH module. By default user
159 credentials are stored in ipsec.secrets.
161 - IKEv2: Support for reauthentication when rekeying
163 - IKEv2: Support for transport mode
165 - fixed a lot of bugs related to byte order
167 - various other bugfixes
173 - IKEv1: Implementation of ModeConfig push mode via the new connection
174 keyword modeconfig=push allows interoperability with Cisco VPN gateways.
176 - IKEv1: The command ipsec statusall now shows "DPD active" for all
177 ISAKMP SAs that are under active Dead Peer Detection control.
179 - IKEv2: Charon's logging and debugging framework has been completely rewritten.
180 Instead of logger, special printf() functions are used to directly
181 print objects like hosts (%H) identifications (%D), certificates (%Q),
182 etc. The number of debugging levels have been reduced to:
184 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private)
186 The debugging levels can either be specified statically in ipsec.conf as
189 charondebug="lib 1, cfg 3, net 2"
191 or changed at runtime via stroke as
193 ipsec stroke loglevel cfg 2
199 - Implemented full support for IPv6-in-IPv6 tunnels.
201 - Added configuration options for dead peer detection in IKEv2. dpd_action
202 types "clear", "hold" and "restart" are supported. The dpd_timeout
203 value is not used, as the normal retransmission policy applies to
204 detect dead peers. The dpd_delay parameter enables sending of empty
205 informational message to detect dead peers in case of inactivity.
207 - Added support for preshared keys in IKEv2. PSK keys configured in
208 ipsec.secrets are loaded. The authby parameter specifies the authentication
209 method to authentificate ourself, the other peer may use PSK or RSA.
211 - Changed retransmission policy to respect the keyingtries parameter.
213 - Added private key decryption. PEM keys encrypted with AES-128/192/256
214 or 3DES are supported.
216 - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to
219 - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates
220 signed with such a hash algorithm.
222 - Added initial support for updown scripts. The actions up-host/client and
223 down-host/client are executed. The leftfirewall=yes parameter
224 uses the default updown script to insert dynamic firewall rules, a custom
225 updown script may be specified with the leftupdown parameter.
231 - Added support for the auto=route ipsec.conf parameter and the
232 ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and
233 CHILD_SAs dynamically on demand when traffic is detected by the
236 - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter.
237 As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only
238 new keys are generated using perfect forward secrecy. An optional flag
239 which enforces reauthentication will be implemented later.
241 - "sha" and "sha1" are now treated as synonyms in the ike= and esp=
242 algorithm configuration statements.
248 - Full X.509 certificate trust chain verification has been implemented.
249 End entity certificates can be exchanged via CERT payloads. The current
250 default is leftsendcert=always, since CERTREQ payloads are not supported
251 yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls.
253 - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2
254 would offer more possibilities for traffic selection, but the Linux kernel
255 currently does not support it. That's why we stick with these simple
256 ipsec.conf rules for now.
258 - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no
259 IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear,
262 - Initial NAT traversal support in IKEv2. Charon includes NAT detection
263 notify payloads to detect NAT routers between the peers. It switches
264 to port 4500, uses UDP encapsulated ESP packets, handles peer address
265 changes gracefully and sends keep alive message periodically.
267 - Reimplemented IKE_SA state machine for charon, which allows simultaneous
268 rekeying, more shared code, cleaner design, proper retransmission
269 and a more extensible code base.
271 - The mixed PSK/RSA roadwarrior detection capability introduced by the
272 strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal
273 payloads by the responder right before any defined IKE Main Mode state had
274 been established. Although any form of bad proposal syntax was being correctly
275 detected by the payload parser, the subsequent error handler didn't check
276 the state pointer before logging current state information, causing an
277 immediate crash of the pluto keying daemon due to a NULL pointer.
283 - Added algorithm selection to charon: New default algorithms for
284 ike=aes128-sha-modp2048, as both daemons support it. The default
285 for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles
286 the ike/esp parameter the same way as pluto. As this syntax does
287 not allow specification of a pseudo random function, the same
288 algorithm as for integrity is used (currently sha/md5). Supported
290 Encryption: aes128, aes192, aes256
291 Integrity/PRF: md5, sha (using hmac)
292 DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192
294 Encryption: aes128, aes192, aes256, 3des, blowfish128,
295 blowfish192, blowfish256
297 More IKE encryption algorithms will come after porting libcrypto into
300 - initial support for rekeying CHILD_SAs using IKEv2. Currently no
301 perfect forward secrecy is used. The rekeying parameters rekey,
302 rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported
303 when using IKEv2. WARNING: charon currently is unable to handle
304 simultaneous rekeying. To avoid such a situation, use a large
305 rekeyfuzz, or even better, set rekey=no on one peer.
307 - support for host2host, net2net, host2net (roadwarrior) tunnels
308 using predefined RSA certificates (see uml scenarios for
309 configuration examples).
311 - new build environment featuring autotools. Features such
312 as HTTP, LDAP and smartcard support may be enabled using
313 the ./configure script. Changing install directories
314 is possible, too. See ./configure --help for more details.
316 - better integration of charon with ipsec starter, which allows
317 (almost) transparent operation with both daemons. charon
318 handles ipsec commands up, down, status, statusall, listall,
319 listcerts and allows proper load, reload and delete of connections
326 - initial support of the IKEv2 protocol. Connections in
327 ipsec.conf designated by keyexchange=ikev2 are negotiated
328 by the new IKEv2 charon keying daemon whereas those marked
329 by keyexchange=ikev1 or the default keyexchange=ike are
330 handled thy the IKEv1 pluto keying daemon. Currently only
331 a limited subset of functions are available with IKEv2
332 (Default AES encryption, authentication based on locally
333 imported X.509 certificates, unencrypted private RSA keys
334 in PKCS#1 file format, limited functionality of the ipsec
341 - the dynamic iptables rules from the _updown_x509 template
342 for KLIPS and the _updown_policy template for NETKEY have
343 been merged into the default _updown script. The existing
344 left|rightfirewall keyword causes the automatic insertion
345 and deletion of ACCEPT rules for tunneled traffic upon
346 the successful setup and teardown of an IPsec SA, respectively.
347 left|rightfirwall can be used with KLIPS under any Linux 2.4
348 kernel or with NETKEY under a Linux kernel version >= 2.6.16
349 in conjuction with iptables >= 1.3.5. For NETKEY under a Linux
350 kernel version < 2.6.16 which does not support IPsec policy
351 matching yet, please continue to use a copy of the _updown_espmark
352 template loaded via the left|rightupdown keyword.
354 - a new left|righthostaccess keyword has been introduced which
355 can be used in conjunction with left|rightfirewall and the
356 default _updown script. By default leftfirewall=yes inserts
357 a bi-directional iptables FORWARD rule for a local client network
358 with a netmask different from 255.255.255.255 (single host).
359 This does not allow to access the VPN gateway host via its
360 internal network interface which is part of the client subnet
361 because an iptables INPUT and OUTPUT rule would be required.
362 lefthostaccess=yes will cause this additional ACCEPT rules to
365 - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal
366 payload is preparsed in order to find out whether the roadwarrior
367 requests PSK or RSA so that a matching connection candidate can
374 - the new _updown_policy template allows ipsec policy based
375 iptables firewall rules. Required are iptables version
376 >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes
377 the _updown_espmark template, so that no INPUT mangle rules
378 are required any more.
380 - added support of DPD restart mode
382 - ipsec starter now allows the use of wildcards in include
383 statements as e.g. in "include /etc/my_ipsec/*.conf".
384 Patch courtesy of Matthias Haas.
386 - the Netscape OID 'employeeNumber' is now recognized and can be
387 used as a Relative Distinguished Name in certificates.
393 - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec
394 command and not of ipsec setup any more.
396 - ipsec starter now supports AH authentication in conjunction with
397 ESP encryption. AH authentication is configured in ipsec.conf
398 via the auth=ah parameter.
400 - The command ipsec scencrypt|scdecrypt <args> is now an alias for
401 ipsec whack --scencrypt|scdecrypt <args>.
403 - get_sa_info() now determines for the native netkey IPsec stack
404 the exact time of the last use of an active eroute. This information
405 is used by the Dead Peer Detection algorithm and is also displayed by
406 the ipsec status command.
412 - running under the native Linux 2.6 IPsec stack, the function
413 get_sa_info() is called by ipsec auto --status to display the current
414 number of transmitted bytes per IPsec SA.
416 - get_sa_info() is also used by the Dead Peer Detection process to detect
417 recent ESP activity. If ESP traffic was received from the peer within
418 the last dpd_delay interval then no R_Y_THERE notification must be sent.
420 - strongSwan now supports the Relative Distinguished Name "unstructuredName"
421 in ID_DER_ASN1_DN identities. The following notations are possible:
423 rightid="unstructuredName=John Doe"
424 rightid="UN=John Doe"
426 - fixed a long-standing bug which caused PSK-based roadwarrior connections
427 to segfault in the function id.c:same_id() called by keys.c:get_secret()
428 if an FQDN, USER_FQDN, or Key ID was defined, as in the following example.
435 - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall).
437 - ipsec starter didn't set host_addr and client.addr ports in whack msg.
439 - in order to guarantee backwards-compatibility with the script-based
440 auto function (e.g. auto --replace), the ipsec starter scripts stores
441 the defaultroute information in the temporary file /var/run/ipsec.info.
443 - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH
444 Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config
447 - the ipsec starter now also recognizes the parameters authby=never and
448 type=passthrough|pass|drop|reject.
454 - ipsec starter now supports the also parameter which allows
455 a modular structure of the connection definitions. Thus
456 "ipsec start" is now ready to replace "ipsec setup".
462 - Mathieu Lafon's popular ipsec starter tool has been added to the
463 strongSwan distribution. Many thanks go to Stephan Scholz from astaro
464 for his integration work. ipsec starter is a C program which is going
465 to replace the various shell and awk starter scripts (setup, _plutoload,
466 _plutostart, _realsetup, _startklips, _confread, and auto). Since
467 ipsec.conf is now parsed only once, the starting of multiple tunnels is
468 accelerated tremedously.
470 - Added support of %defaultroute to the ipsec starter. If the IP address
471 changes, a HUP signal to the ipsec starter will automatically
472 reload pluto's connections.
474 - moved most compile time configurations from pluto/Makefile to
475 Makefile.inc by defining the options USE_LIBCURL, USE_LDAP,
476 USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE.
478 - removed the ipsec verify and ipsec newhostkey commands
480 - fixed some 64-bit issues in formatted print statements
482 - The scepclient functionality implementing the Simple Certificate
483 Enrollment Protocol (SCEP) is nearly complete but hasn't been
490 - CA certicates are now automatically loaded from a smartcard
491 or USB crypto token and appear in the ipsec auto --listcacerts
498 - when using "ipsec whack --scencrypt <data>" with a PKCS#11
499 library that does not support the C_Encrypt() Cryptoki
500 function (e.g. OpenSC), the RSA encryption is done in
501 software using the public key fetched from the smartcard.
503 - The scepclient function now allows to define the
504 validity of a self-signed certificate using the --days,
505 --startdate, and --enddate options. The default validity
506 has been changed from one year to five years.
512 - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11
513 interface to other applications for RSA encryption and decryption
514 via the whack interface. Notation:
516 ipsec whack --scencrypt <data>
517 [--inbase 16|hex|64|base64|256|text|ascii]
518 [--outbase 16|hex|64|base64|256|text|ascii]
521 ipsec whack --scdecrypt <data>
522 [--inbase 16|hex|64|base64|256|text|ascii]
523 [--outbase 16|hex|64|base64|256|text|ascii]
526 The default setting for inbase and outbase is hex.
528 The new proxy interface can be used for securing symmetric
529 encryption keys required by the cryptoloop or dm-crypt
530 disk encryption schemes, especially in the case when
531 pkcs11keepstate=yes causes pluto to lock the pkcs11 slot
534 - if the file /etc/ipsec.secrets is lacking during the startup of
535 pluto then the root-readable file /etc/ipsec.d/private/myKey.der
536 containing a 2048 bit RSA private key and a matching self-signed
537 certificate stored in the file /etc/ipsec.d/certs/selfCert.der
538 is automatically generated by calling the function
540 ipsec scepclient --out pkcs1 --out cert-self
542 scepclient was written by Jan Hutter and Martin Willi, students
543 at the University of Applied Sciences in Rapperswil, Switzerland.
549 - the current extension of the PKCS#7 framework introduced
550 a parsing error in PKCS#7 wrapped X.509 certificates that are
551 e.g. transmitted by Windows XP when multi-level CAs are used.
552 the parsing syntax has been fixed.
554 - added a patch by Gerald Richter which tolerates multiple occurrences
555 of the ipsec0 interface when using KLIPS.
561 - with gawk-3.1.4 the word "default2 has become a protected
562 keyword for use in switch statements and cannot be used any
563 more in the strongSwan scripts. This problem has been
564 solved by renaming "default" to "defaults" and "setdefault"
565 in the scripts _confread and auto, respectively.
567 - introduced the parameter leftsendcert with the values
569 always|yes (the default, always send a cert)
570 ifasked (send the cert only upon a cert request)
571 never|no (never send a cert, used for raw RSA keys and
574 - fixed the initialization of the ESP key length to a default of
575 128 bits in the case that the peer does not send a key length
576 attribute for AES encryption.
578 - applied Herbert Xu's uniqueIDs patch
580 - applied Herbert Xu's CLOEXEC patches
586 - CRLs can now be cached also in the case when the issuer's
587 certificate does not contain a subjectKeyIdentifier field.
588 In that case the subjectKeyIdentifier is computed by pluto as the
589 160 bit SHA-1 hash of the issuer's public key in compliance
590 with section 4.2.1.2 of RFC 3280.
592 - Fixed a bug introduced by strongswan-2.5.1 which eliminated
593 not only multiple Quick Modes of a given connection but also
594 multiple connections between two security gateways.
600 - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute
601 installed either by setting auto=route in ipsec.conf or by
602 a connection put into hold, generates an XFRM_AQUIRE event
603 for each packet that wants to use the not-yet exisiting
604 tunnel. Up to now each XFRM_AQUIRE event led to an entry in
605 the Quick Mode queue, causing multiple IPsec SA to be
606 established in rapid succession. Starting with strongswan-2.5.1
607 only a single IPsec SA is established per host-pair connection.
609 - Right after loading the PKCS#11 module, all smartcard slots are
610 searched for certificates. The result can be viewed using
613 ipsec auto --listcards
615 The certificate objects found in the slots are numbered
616 starting with #1, #2, etc. This position number can be used to address
617 certificates (leftcert=%smartcard) and keys (: PIN %smartcard)
618 in ipsec.conf and ipsec.secrets, respectively:
620 %smartcard (selects object #1)
621 %smartcard#1 (selects object #1)
622 %smartcard#3 (selects object #3)
624 As an alternative the existing retrieval scheme can be used:
626 %smartcard:45 (selects object with id=45)
627 %smartcard0 (selects first object in slot 0)
628 %smartcard4:45 (selects object in slot 4 with id=45)
630 - Depending on the settings of CKA_SIGN and CKA_DECRYPT
631 private key flags either C_Sign() or C_Decrypt() is used
632 to generate a signature.
634 - The output buffer length parameter siglen in C_Sign()
635 is now initialized to the actual size of the output
636 buffer prior to the function call. This fixes the
637 CKR_BUFFER_TOO_SMALL error that could occur when using
638 the OpenSC PKCS#11 module.
640 - Changed the initialization of the PKCS#11 CK_MECHANISM in
641 C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }.
643 - Refactored the RSA public/private key code and transferred it
644 from keys.c to the new pkcs1.c file as a preparatory step
645 towards the release of the SCEP client.
651 - The loading of a PKCS#11 smartcard library module during
652 runtime does not require OpenSC library functions any more
653 because the corresponding code has been integrated into
654 smartcard.c. Also the RSAREF pkcs11 header files have been
655 included in a newly created pluto/rsaref directory so that
656 no external include path has to be defined any longer.
658 - A long-awaited feature has been implemented at last:
659 The local caching of CRLs fetched via HTTP or LDAP, activated
660 by the parameter cachecrls=yes in the config setup section
661 of ipsec.conf. The dynamically fetched CRLs are stored under
662 a unique file name containing the issuer's subjectKeyID
663 in /etc/ipsec.d/crls.
665 - Applied a one-line patch courtesy of Michael Richardson
666 from the Openswan project which fixes the kernel-oops
667 in KLIPS when an snmp daemon is running on the same box.
673 - Eliminated null length CRL distribution point strings.
675 - Fixed a trust path evaluation bug introduced with 2.4.3
681 - Improved the joint OCSP / CRL revocation policy.
682 OCSP responses have precedence over CRL entries.
684 - Introduced support of CRLv2 reason codes.
686 - Fixed a bug with key-pad equipped readers which caused
687 pluto to prompt for the pin via the console when the first
688 occasion to enter the pin via the key-pad was missed.
690 - When pluto is built with LDAP_V3 enabled, the library
691 liblber required by newer versions of openldap is now
698 - Added the _updown_espmark template which requires all
699 incoming ESP traffic to be marked with a default mark
702 - Introduced the pkcs11keepstate parameter in the config setup
703 section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11
704 session and login states are kept as long as possible during
705 the lifetime of pluto. This means that a PIN entry via a key
706 pad has to be done only once.
708 - Introduced the pkcs11module parameter in the config setup
709 section of ipsec.conf which specifies the PKCS#11 module
710 to be used with smart cards. Example:
712 pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo
714 - Added support of smartcard readers equipped with a PIN pad.
716 - Added patch by Jay Pfeifer which detects when netkey
717 modules have been statically built into the Linux 2.6 kernel.
719 - Added two patches by Herbert Xu. The first uses ip xfrm
720 instead of setkey to flush the IPsec policy database. The
721 second sets the optional flag in inbound IPComp SAs only.
723 - Applied Ulrich Weber's patch which fixes an interoperability
724 problem between native IPsec and KLIPS systems caused by
725 setting the replay window to 32 instead of 0 for ipcomp.
731 - Fixed a bug which caused an unwanted Mode Config request
732 to be initiated in the case where "right" was used to denote
733 the local side in ipsec.conf and "left" the remote side,
734 contrary to the recommendation that "right" be remote and
741 - updated Vendor ID to strongSwan-2.4.0
743 - updated copyright statement to include David Buechi and
750 - strongSwan now communicates with attached smartcards and
751 USB crypto tokens via the standardized PKCS #11 interface.
752 By default the OpenSC library from www.opensc.org is used
753 but any other PKCS#11 library could be dynamically linked.
754 strongSwan's PKCS#11 API was implemented by David Buechi
755 and Michael Meier, both graduates of the Zurich University
756 of Applied Sciences in Winterthur, Switzerland.
758 - When a %trap eroute is triggered by an outgoing IP packet
759 then the native IPsec stack of the Linux 2.6 kernel [often/
760 always?] returns an XFRM_ACQUIRE message with an undefined
761 protocol family field and the connection setup fails.
762 As a workaround IPv4 (AF_INET) is now assumed.
764 - the results of the UML test scenarios are now enhanced
765 with block diagrams of the virtual network topology used
766 in a particular test.
772 - fixed IV used to decrypt informational messages.
773 This bug was introduced with Mode Config functionality.
775 - fixed NCP Vendor ID.
777 - undid one of Ulrich Weber's maximum udp size patches
778 because it caused a segmentation fault with NAT-ed
781 - added UML scenarios wildcards and attr-cert which
782 demonstrate the implementation of IPsec policies based
783 on wildcard parameters contained in Distinguished Names and
784 on X.509 attribute certificates, respectively.
790 - Added basic Mode Config functionality
792 - Added Mathieu Lafon's patch which upgrades the status of
793 the NAT-Traversal implementation to RFC 3947.
795 - The _startklips script now also loads the xfrm4_tunnel
798 - Added Ulrich Weber's netlink replay window size and
799 maximum udp size patches.
801 - UML testing now uses the Linux 2.6.10 UML kernel by default.
807 - Eric Marchionni and Patrik Rayo, both recent graduates from
808 the Zuercher Hochschule Winterthur in Switzerland, created a
809 User-Mode-Linux test setup for strongSwan. For more details
810 please read the INSTALL and README documents in the testing
813 - Full support of group attributes based on X.509 attribute
814 certificates. Attribute certificates can be generated
815 using the openac facility. For more details see
819 The group attributes can be used in connection definitions
820 in order to give IPsec access to specific user groups.
821 This is done with the new parameter left|rightgroups as in
823 rightgroups="Research, Sales"
825 giving access to users possessing the group attributes
826 Research or Sales, only.
828 - In Quick Mode clients with subnet mask /32 are now
829 coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should
830 fix rekeying problems with the SafeNet/SoftRemote and NCP
831 Secure Entry Clients.
833 - Changed the defaults of the ikelifetime and keylife parameters
834 to 3h and 1h, respectively. The maximum allowable values are
835 now both set to 24 h.
837 - Suppressed notification wars between two IPsec peers that
838 could e.g. be triggered by incorrect ISAKMP encryption.
840 - Public RSA keys can now have identical IDs if either the
841 issuing CA or the serial number is different. The serial
842 number of a certificate is now shown by the command
844 ipsec auto --listpubkeys
850 - Added Tuomo Soini's sourceip feature which allows a strongSwan
851 roadwarrior to use a fixed Virtual IP (see README section 2.6)
852 and reduces the well-known four tunnel case on VPN gateways to
853 a single tunnel definition (see README section 2.4).
855 - Fixed a bug occuring with NAT-Traversal enabled when the responder
856 suddenly turns initiator and the initiator cannot find a matching
857 connection because of the floated IKE port 4500.
859 - Removed misleading ipsec verify command from barf.
861 - Running under the native IP stack, ipsec --version now shows
862 the Linux kernel version (courtesy to the Openswan project).
868 - Introduced the ipsec auto --listalgs monitoring command which lists
869 all currently registered IKE and ESP algorithms.
871 - Fixed a bug in the ESP algorithm selection occuring when the strict flag
872 is set and the first proposed transform does not match.
874 - Fixed another deadlock in the use of the lock_certs_and_keys() mutex,
875 occuring when a smartcard is present.
877 - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event.
879 - Fixed the printing of the notification names (null)
881 - Applied another of Herbert Xu's Netlink patches.
887 - Support of Dead Peer Detection. The connection parameter
891 activates DPD for the given connection.
893 - The default Opportunistic Encryption (OE) policy groups are not
894 automatically included anymore. Those wishing to activate OE can include
895 the policy group with the following statement in ipsec.conf:
897 include /etc/ipsec.d/examples/oe.conf
899 The default for [right|left]rsasigkey is now set to %cert.
901 - strongSwan now has a Vendor ID of its own which can be activated
902 using the compile option VENDORID
904 - Applied Herbert Xu's patch which sets the compression algorithm correctly.
906 - Applied Herbert Xu's patch fixing an ESPINUDP problem
908 - Applied Herbert Xu's patch setting source/destination port numbers.
910 - Reapplied one of Herbert Xu's NAT-Traversal patches which got
911 lost during the migration from SuperFreeS/WAN.
913 - Fixed a deadlock in the use of the lock_certs_and_keys() mutex.
915 - Fixed the unsharing of alg parameters when instantiating group
922 - Thomas Walpuski made me aware of a potential DoS attack via
923 a PKCS#7-wrapped certificate bundle which could overwrite valid CA
924 certificates in Pluto's authority certificate store. This vulnerability
925 was fixed by establishing trust in CA candidate certificates up to a
926 trusted root CA prior to insertion into Pluto's chained list.
928 - replaced the --assign option by the -v option in the auto awk script
929 in order to make it run with mawk under debian/woody.
935 - Split of the status information between ipsec auto --status (concise)
936 and ipsec auto --statusall (verbose). Both commands can be used with
937 an optional connection selector:
939 ipsec auto --status[all] <connection_name>
941 - Added the description of X.509 related features to the ipsec_auto(8)
944 - Hardened the ASN.1 parser in debug mode, especially the printing
945 of malformed distinguished names.
947 - The size of an RSA public key received in a certificate is now restricted to
949 512 bits <= modulus length <= 8192 bits.
951 - Fixed the debug mode enumeration.
957 - Fixed another PKCS#7 vulnerability which could lead to an
958 endless loop while following the X.509 trust chain.
964 - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski
965 that accepted end certificates having identical issuer and subject
966 distinguished names in a multi-tier X.509 trust chain.
972 - Removed all remaining references to ipsec_netlink.h in KLIPS.
978 - The new "ca" section allows to define the following parameters:
981 cacert=koolCA.pem # cacert of kool CA
982 ocspuri=http://ocsp.kool.net:8001 # ocsp server
983 ldapserver=ldap.kool.net # default ldap server
984 crluri=http://www.kool.net/kool.crl # crl distribution point
985 crluri2="ldap:///O=Kool, C= .." # crl distribution point #2
986 auto=add # add, ignore
988 The ca definitions can be monitored via the command
990 ipsec auto --listcainfos
992 - Fixed cosmetic corruption of /proc filesystem by integrating
993 D. Hugh Redelmeier's freeswan-2.06 kernel fixes.
999 - Added support for the 818043 NAT-Traversal update of Microsoft's
1000 Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode.
1002 - A symbolic link to libcrypto is now added in the kernel sources
1003 during kernel compilation
1005 - Fixed a couple of 64 bit issues (mostly casts to int).
1006 Thanks to Ken Bantoft who checked my sources on a 64 bit platform.
1008 - Replaced s[n]printf() statements in the kernel by ipsec_snprintf().
1009 Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro
1010 of the FreeS/WAN team who solved this problem with the 2.4.25 kernel.
1016 - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName
1017 certificate extension which contains no generalName item) can cause
1018 a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has
1019 been hardened to make it more robust against malformed ASN.1 objects.
1021 - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native
1022 Linux 2.6 IPsec stack.
1028 - based on freeswan-2.04, x509-1.5.3, nat-0.6c, alg-0.8.1rc12
