1 | strongswan-4.1.3 | |
2 | ---------------- | |
3 | ||
4 | - IKEv2 peer configuration selection can now be based on a required | |
5 | certification authority using the rightca= statement. | |
6 | ||
7 | - IKEv2 authentication based on RSA signatures now can handle multiple | |
8 | certificates issued for a given peer ID. | |
9 | ||
10 | ||
11 | strongswan-4.1.2 | |
12 | ---------------- | |
13 | ||
14 | - Support for an additional Diffie-Hellman exchange when creating/rekeying | |
15 | a CHILD_SA in IKEv2 (PFS). PFS is enabled when the proposal contains a | |
16 | DH group (e.g. "esp=aes128-sha1-modp1536"). Further, DH group negotiation | |
17 | is implemented properly for rekeying. | |
18 | ||
19 | - Support for the AES-XCBC-96 MAC algorithm for IPsec SAs when using IKEv2 | |
20 | (requires linux >= 2.6.20). It is enabled using e.g. "esp=aes256-aesxcbc". | |
21 | ||
22 | - Working IPv4-in-IPv6 and IPv6-in-IPv4 tunnels for linux >= 2.6.21. | |
23 | ||
24 | - Added support for EAP modules which do not establish an MSK. | |
25 | ||
26 | - Removed the dependencies from the /usr/include/linux/ headers by | |
27 | including xfrm.h, ipsec.h, and pfkeyv2.h in the distribution. | |
28 | ||
29 | - crlNumber is now listed by ipsec listcrls | |
30 | ||
31 | - The xauth_modules.verify_secret() function now passes the | |
32 | connection name. | |
33 | ||
34 | ||
35 | strongswan-4.1.1 | |
36 | ---------------- | |
37 | ||
38 | - Server side cookie support. If to may IKE_SAs are in CONNECTING state, | |
39 | cookies are enabled and protect against DoS attacks with faked source | |
40 | addresses. Number of IKE_SAs in CONNECTING state is also limited per | |
41 | peer address to avoid resource exhaustion. IKE_SA_INIT messages are | |
42 | compared to properly detect retransmissions and incoming retransmits are | |
43 | detected even if the IKE_SA is blocked (e.g. doing OCSP fetches). | |
44 | ||
45 | - The IKEv2 daemon charon now supports dynamic http- and ldap-based CRL | |
46 | fetching enabled by crlcheckinterval > 0 and caching fetched CRLs | |
47 | enabled by cachecrls=yes. | |
48 | ||
49 | - Added the configuration options --enable-nat-transport which enables | |
50 | the potentially insecure NAT traversal for IPsec transport mode and | |
51 | --disable-vendor-id which disables the sending of the strongSwan | |
52 | vendor ID. | |
53 | ||
54 | - Fixed a long-standing bug in the pluto IKEv1 daemon which caused | |
55 | a segmentation fault if a malformed payload was detected in the | |
56 | IKE MR2 message and pluto tried to send an encrypted notification | |
57 | message. | |
58 | ||
59 | - Added the NATT_IETF_02_N Vendor ID in order to support IKEv1 connections | |
60 | with Windows 2003 Server which uses a wrong VID hash. | |
61 | ||
62 | ||
63 | strongswan-4.1.0 | |
64 | ---------------- | |
65 | ||
66 | - Support of SHA2_384 hash function for protecting IKEv1 | |
67 | negotiations and support of SHA2 signatures in X.509 certificates. | |
68 | ||
69 | - Fixed a serious bug in the computation of the SHA2-512 HMAC | |
70 | function. Introduced automatic self-test of all IKEv1 hash | |
71 | and hmac functions during pluto startup. Failure of a self-test | |
72 | currently issues a warning only but does not exit pluto [yet]. | |
73 | ||
74 | - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2. | |
75 | ||
76 | - Full support of CA information sections. ipsec listcainfos | |
77 | now shows all collected crlDistributionPoints and OCSP | |
78 | accessLocations. | |
79 | ||
80 | - Support of the Online Certificate Status Protocol (OCSP) for IKEv2. | |
81 | This feature requires the HTTP fetching capabilities of the libcurl | |
82 | library which must be enabled by setting the --enable-http configure | |
83 | option. | |
84 | ||
85 | - Refactored core of the IKEv2 message processing code, allowing better | |
86 | code reuse and separation. | |
87 | ||
88 | - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration | |
89 | payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted | |
90 | by the requestor and installed in a resolv.conf file. | |
91 | ||
92 | - The IKEv2 daemon charon installs a route for each IPsec policy to use | |
93 | the correct source address even if an application does not explicitly | |
94 | specify it. | |
95 | ||
96 | - Integrated the EAP framework into charon which loads pluggable EAP library | |
97 | modules. The ipsec.conf parameter authby=eap initiates EAP authentication | |
98 | on the client side, while the "eap" parameter on the server side defines | |
99 | the EAP method to use for client authentication. | |
100 | A generic client side EAP-Identity module and an EAP-SIM authentication | |
101 | module using a third party card reader implementation are included. | |
102 | ||
103 | - Added client side support for cookies. | |
104 | ||
105 | - Integrated the fixes done at the IKEv2 interoperability bakeoff, including | |
106 | strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor | |
107 | fixes to enhance interoperability with other implementations. | |
108 | ||
109 | ||
110 | strongswan-4.0.7 | |
111 | ---------------- | |
112 | ||
113 | - strongSwan now interoperates with the NCP Secure Entry Client, | |
114 | the Shrew Soft VPN Client, and the Cisco VPN client, doing both | |
115 | XAUTH and Mode Config. | |
116 | ||
117 | - UNITY attributes are now recognized and UNITY_BANNER is set | |
118 | to a default string. | |
119 | ||
120 | ||
121 | strongswan-4.0.6 | |
122 | ---------------- | |
123 | ||
124 | - IKEv1: Support for extended authentication (XAUTH) in combination | |
125 | with ISAKMP Main Mode RSA or PSK authentication. Both client and | |
126 | server side were implemented. Handling of user credentials can | |
127 | be done by a run-time loadable XAUTH module. By default user | |
128 | credentials are stored in ipsec.secrets. | |
129 | ||
130 | - IKEv2: Support for reauthentication when rekeying | |
131 | ||
132 | - IKEv2: Support for transport mode | |
133 | ||
134 | - fixed a lot of bugs related to byte order | |
135 | ||
136 | - various other bugfixes | |
137 | ||
138 | ||
139 | strongswan-4.0.5 | |
140 | ---------------- | |
141 | ||
142 | - IKEv1: Implementation of ModeConfig push mode via the new connection | |
143 | keyword modeconfig=push allows interoperability with Cisco VPN gateways. | |
144 | ||
145 | - IKEv1: The command ipsec statusall now shows "DPD active" for all | |
146 | ISAKMP SAs that are under active Dead Peer Detection control. | |
147 | ||
148 | - IKEv2: Charon's logging and debugging framework has been completely rewritten. | |
149 | Instead of logger, special printf() functions are used to directly | |
150 | print objects like hosts (%H) identifications (%D), certificates (%Q), | |
151 | etc. The number of debugging levels have been reduced to: | |
152 | ||
153 | 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private) | |
154 | ||
155 | The debugging levels can either be specified statically in ipsec.conf as | |
156 | ||
157 | config setup | |
158 | charondebug="lib 1, cfg 3, net 2" | |
159 | ||
160 | or changed at runtime via stroke as | |
161 | ||
162 | ipsec stroke loglevel cfg 2 | |
163 | ||
164 | ||
165 | strongswan-4.0.4 | |
166 | ---------------- | |
167 | ||
168 | - Implemented full support for IPv6-in-IPv6 tunnels. | |
169 | ||
170 | - Added configuration options for dead peer detection in IKEv2. dpd_action | |
171 | types "clear", "hold" and "restart" are supported. The dpd_timeout | |
172 | value is not used, as the normal retransmission policy applies to | |
173 | detect dead peers. The dpd_delay parameter enables sending of empty | |
174 | informational message to detect dead peers in case of inactivity. | |
175 | ||
176 | - Added support for preshared keys in IKEv2. PSK keys configured in | |
177 | ipsec.secrets are loaded. The authby parameter specifies the authentication | |
178 | method to authentificate ourself, the other peer may use PSK or RSA. | |
179 | ||
180 | - Changed retransmission policy to respect the keyingtries parameter. | |
181 | ||
182 | - Added private key decryption. PEM keys encrypted with AES-128/192/256 | |
183 | or 3DES are supported. | |
184 | ||
185 | - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to | |
186 | encrypt IKE traffic. | |
187 | ||
188 | - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates | |
189 | signed with such a hash algorithm. | |
190 | ||
191 | - Added initial support for updown scripts. The actions up-host/client and | |
192 | down-host/client are executed. The leftfirewall=yes parameter | |
193 | uses the default updown script to insert dynamic firewall rules, a custom | |
194 | updown script may be specified with the leftupdown parameter. | |
195 | ||
196 | ||
197 | strongswan-4.0.3 | |
198 | ---------------- | |
199 | ||
200 | - Added support for the auto=route ipsec.conf parameter and the | |
201 | ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and | |
202 | CHILD_SAs dynamically on demand when traffic is detected by the | |
203 | kernel. | |
204 | ||
205 | - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter. | |
206 | As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only | |
207 | new keys are generated using perfect forward secrecy. An optional flag | |
208 | which enforces reauthentication will be implemented later. | |
209 | ||
210 | - "sha" and "sha1" are now treated as synonyms in the ike= and esp= | |
211 | algorithm configuration statements. | |
212 | ||
213 | ||
214 | strongswan-4.0.2 | |
215 | ---------------- | |
216 | ||
217 | - Full X.509 certificate trust chain verification has been implemented. | |
218 | End entity certificates can be exchanged via CERT payloads. The current | |
219 | default is leftsendcert=always, since CERTREQ payloads are not supported | |
220 | yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls. | |
221 | ||
222 | - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2 | |
223 | would offer more possibilities for traffic selection, but the Linux kernel | |
224 | currently does not support it. That's why we stick with these simple | |
225 | ipsec.conf rules for now. | |
226 | ||
227 | - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no | |
228 | IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear, | |
229 | dpddelay=60s). | |
230 | ||
231 | - Initial NAT traversal support in IKEv2. Charon includes NAT detection | |
232 | notify payloads to detect NAT routers between the peers. It switches | |
233 | to port 4500, uses UDP encapsulated ESP packets, handles peer address | |
234 | changes gracefully and sends keep alive message periodically. | |
235 | ||
236 | - Reimplemented IKE_SA state machine for charon, which allows simultaneous | |
237 | rekeying, more shared code, cleaner design, proper retransmission | |
238 | and a more extensible code base. | |
239 | ||
240 | - The mixed PSK/RSA roadwarrior detection capability introduced by the | |
241 | strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal | |
242 | payloads by the responder right before any defined IKE Main Mode state had | |
243 | been established. Although any form of bad proposal syntax was being correctly | |
244 | detected by the payload parser, the subsequent error handler didn't check | |
245 | the state pointer before logging current state information, causing an | |
246 | immediate crash of the pluto keying daemon due to a NULL pointer. | |
247 | ||
248 | ||
249 | strongswan-4.0.1 | |
250 | ---------------- | |
251 | ||
252 | - Added algorithm selection to charon: New default algorithms for | |
253 | ike=aes128-sha-modp2048, as both daemons support it. The default | |
254 | for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles | |
255 | the ike/esp parameter the same way as pluto. As this syntax does | |
256 | not allow specification of a pseudo random function, the same | |
257 | algorithm as for integrity is used (currently sha/md5). Supported | |
258 | algorithms for IKE: | |
259 | Encryption: aes128, aes192, aes256 | |
260 | Integrity/PRF: md5, sha (using hmac) | |
261 | DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192 | |
262 | and for ESP: | |
263 | Encryption: aes128, aes192, aes256, 3des, blowfish128, | |
264 | blowfish192, blowfish256 | |
265 | Integrity: md5, sha1 | |
266 | More IKE encryption algorithms will come after porting libcrypto into | |
267 | libstrongswan. | |
268 | ||
269 | - initial support for rekeying CHILD_SAs using IKEv2. Currently no | |
270 | perfect forward secrecy is used. The rekeying parameters rekey, | |
271 | rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported | |
272 | when using IKEv2. WARNING: charon currently is unable to handle | |
273 | simultaneous rekeying. To avoid such a situation, use a large | |
274 | rekeyfuzz, or even better, set rekey=no on one peer. | |
275 | ||
276 | - support for host2host, net2net, host2net (roadwarrior) tunnels | |
277 | using predefined RSA certificates (see uml scenarios for | |
278 | configuration examples). | |
279 | ||
280 | - new build environment featuring autotools. Features such | |
281 | as HTTP, LDAP and smartcard support may be enabled using | |
282 | the ./configure script. Changing install directories | |
283 | is possible, too. See ./configure --help for more details. | |
284 | ||
285 | - better integration of charon with ipsec starter, which allows | |
286 | (almost) transparent operation with both daemons. charon | |
287 | handles ipsec commands up, down, status, statusall, listall, | |
288 | listcerts and allows proper load, reload and delete of connections | |
289 | via ipsec starter. | |
290 | ||
291 | ||
292 | strongswan-4.0.0 | |
293 | ---------------- | |
294 | ||
295 | - initial support of the IKEv2 protocol. Connections in | |
296 | ipsec.conf designated by keyexchange=ikev2 are negotiated | |
297 | by the new IKEv2 charon keying daemon whereas those marked | |
298 | by keyexchange=ikev1 or the default keyexchange=ike are | |
299 | handled thy the IKEv1 pluto keying daemon. Currently only | |
300 | a limited subset of functions are available with IKEv2 | |
301 | (Default AES encryption, authentication based on locally | |
302 | imported X.509 certificates, unencrypted private RSA keys | |
303 | in PKCS#1 file format, limited functionality of the ipsec | |
304 | status command). | |
305 | ||
306 | ||
307 | strongswan-2.7.0 | |
308 | ---------------- | |
309 | ||
310 | - the dynamic iptables rules from the _updown_x509 template | |
311 | for KLIPS and the _updown_policy template for NETKEY have | |
312 | been merged into the default _updown script. The existing | |
313 | left|rightfirewall keyword causes the automatic insertion | |
314 | and deletion of ACCEPT rules for tunneled traffic upon | |
315 | the successful setup and teardown of an IPsec SA, respectively. | |
316 | left|rightfirwall can be used with KLIPS under any Linux 2.4 | |
317 | kernel or with NETKEY under a Linux kernel version >= 2.6.16 | |
318 | in conjuction with iptables >= 1.3.5. For NETKEY under a Linux | |
319 | kernel version < 2.6.16 which does not support IPsec policy | |
320 | matching yet, please continue to use a copy of the _updown_espmark | |
321 | template loaded via the left|rightupdown keyword. | |
322 | ||
323 | - a new left|righthostaccess keyword has been introduced which | |
324 | can be used in conjunction with left|rightfirewall and the | |
325 | default _updown script. By default leftfirewall=yes inserts | |
326 | a bi-directional iptables FORWARD rule for a local client network | |
327 | with a netmask different from 255.255.255.255 (single host). | |
328 | This does not allow to access the VPN gateway host via its | |
329 | internal network interface which is part of the client subnet | |
330 | because an iptables INPUT and OUTPUT rule would be required. | |
331 | lefthostaccess=yes will cause this additional ACCEPT rules to | |
332 | be inserted. | |
333 | ||
334 | - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal | |
335 | payload is preparsed in order to find out whether the roadwarrior | |
336 | requests PSK or RSA so that a matching connection candidate can | |
337 | be found. | |
338 | ||
339 | ||
340 | strongswan-2.6.4 | |
341 | ---------------- | |
342 | ||
343 | - the new _updown_policy template allows ipsec policy based | |
344 | iptables firewall rules. Required are iptables version | |
345 | >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes | |
346 | the _updown_espmark template, so that no INPUT mangle rules | |
347 | are required any more. | |
348 | ||
349 | - added support of DPD restart mode | |
350 | ||
351 | - ipsec starter now allows the use of wildcards in include | |
352 | statements as e.g. in "include /etc/my_ipsec/*.conf". | |
353 | Patch courtesy of Matthias Haas. | |
354 | ||
355 | - the Netscape OID 'employeeNumber' is now recognized and can be | |
356 | used as a Relative Distinguished Name in certificates. | |
357 | ||
358 | ||
359 | strongswan-2.6.3 | |
360 | ---------------- | |
361 | ||
362 | - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec | |
363 | command and not of ipsec setup any more. | |
364 | ||
365 | - ipsec starter now supports AH authentication in conjunction with | |
366 | ESP encryption. AH authentication is configured in ipsec.conf | |
367 | via the auth=ah parameter. | |
368 | ||
369 | - The command ipsec scencrypt|scdecrypt <args> is now an alias for | |
370 | ipsec whack --scencrypt|scdecrypt <args>. | |
371 | ||
372 | - get_sa_info() now determines for the native netkey IPsec stack | |
373 | the exact time of the last use of an active eroute. This information | |
374 | is used by the Dead Peer Detection algorithm and is also displayed by | |
375 | the ipsec status command. | |
376 | ||
377 | ||
378 | strongswan-2.6.2 | |
379 | ---------------- | |
380 | ||
381 | - running under the native Linux 2.6 IPsec stack, the function | |
382 | get_sa_info() is called by ipsec auto --status to display the current | |
383 | number of transmitted bytes per IPsec SA. | |
384 | ||
385 | - get_sa_info() is also used by the Dead Peer Detection process to detect | |
386 | recent ESP activity. If ESP traffic was received from the peer within | |
387 | the last dpd_delay interval then no R_Y_THERE notification must be sent. | |
388 | ||
389 | - strongSwan now supports the Relative Distinguished Name "unstructuredName" | |
390 | in ID_DER_ASN1_DN identities. The following notations are possible: | |
391 | ||
392 | rightid="unstructuredName=John Doe" | |
393 | rightid="UN=John Doe" | |
394 | ||
395 | - fixed a long-standing bug which caused PSK-based roadwarrior connections | |
396 | to segfault in the function id.c:same_id() called by keys.c:get_secret() | |
397 | if an FQDN, USER_FQDN, or Key ID was defined, as in the following example. | |
398 | ||
399 | conn rw | |
400 | right=%any | |
401 | rightid=@foo.bar | |
402 | authby=secret | |
403 | ||
404 | - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall). | |
405 | ||
406 | - ipsec starter didn't set host_addr and client.addr ports in whack msg. | |
407 | ||
408 | - in order to guarantee backwards-compatibility with the script-based | |
409 | auto function (e.g. auto --replace), the ipsec starter scripts stores | |
410 | the defaultroute information in the temporary file /var/run/ipsec.info. | |
411 | ||
412 | - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH | |
413 | Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config | |
414 | servers. | |
415 | ||
416 | - the ipsec starter now also recognizes the parameters authby=never and | |
417 | type=passthrough|pass|drop|reject. | |
418 | ||
419 | ||
420 | strongswan-2.6.1 | |
421 | ---------------- | |
422 | ||
423 | - ipsec starter now supports the also parameter which allows | |
424 | a modular structure of the connection definitions. Thus | |
425 | "ipsec start" is now ready to replace "ipsec setup". | |
426 | ||
427 | ||
428 | strongswan-2.6.0 | |
429 | ---------------- | |
430 | ||
431 | - Mathieu Lafon's popular ipsec starter tool has been added to the | |
432 | strongSwan distribution. Many thanks go to Stephan Scholz from astaro | |
433 | for his integration work. ipsec starter is a C program which is going | |
434 | to replace the various shell and awk starter scripts (setup, _plutoload, | |
435 | _plutostart, _realsetup, _startklips, _confread, and auto). Since | |
436 | ipsec.conf is now parsed only once, the starting of multiple tunnels is | |
437 | accelerated tremedously. | |
438 | ||
439 | - Added support of %defaultroute to the ipsec starter. If the IP address | |
440 | changes, a HUP signal to the ipsec starter will automatically | |
441 | reload pluto's connections. | |
442 | ||
443 | - moved most compile time configurations from pluto/Makefile to | |
444 | Makefile.inc by defining the options USE_LIBCURL, USE_LDAP, | |
445 | USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE. | |
446 | ||
447 | - removed the ipsec verify and ipsec newhostkey commands | |
448 | ||
449 | - fixed some 64-bit issues in formatted print statements | |
450 | ||
451 | - The scepclient functionality implementing the Simple Certificate | |
452 | Enrollment Protocol (SCEP) is nearly complete but hasn't been | |
453 | documented yet. | |
454 | ||
455 | ||
456 | strongswan-2.5.7 | |
457 | ---------------- | |
458 | ||
459 | - CA certicates are now automatically loaded from a smartcard | |
460 | or USB crypto token and appear in the ipsec auto --listcacerts | |
461 | listing. | |
462 | ||
463 | ||
464 | strongswan-2.5.6 | |
465 | ---------------- | |
466 | ||
467 | - when using "ipsec whack --scencrypt <data>" with a PKCS#11 | |
468 | library that does not support the C_Encrypt() Cryptoki | |
469 | function (e.g. OpenSC), the RSA encryption is done in | |
470 | software using the public key fetched from the smartcard. | |
471 | ||
472 | - The scepclient function now allows to define the | |
473 | validity of a self-signed certificate using the --days, | |
474 | --startdate, and --enddate options. The default validity | |
475 | has been changed from one year to five years. | |
476 | ||
477 | ||
478 | strongswan-2.5.5 | |
479 | ---------------- | |
480 | ||
481 | - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11 | |
482 | interface to other applications for RSA encryption and decryption | |
483 | via the whack interface. Notation: | |
484 | ||
485 | ipsec whack --scencrypt <data> | |
486 | [--inbase 16|hex|64|base64|256|text|ascii] | |
487 | [--outbase 16|hex|64|base64|256|text|ascii] | |
488 | [--keyid <keyid>] | |
489 | ||
490 | ipsec whack --scdecrypt <data> | |
491 | [--inbase 16|hex|64|base64|256|text|ascii] | |
492 | [--outbase 16|hex|64|base64|256|text|ascii] | |
493 | [--keyid <keyid>] | |
494 | ||
495 | The default setting for inbase and outbase is hex. | |
496 | ||
497 | The new proxy interface can be used for securing symmetric | |
498 | encryption keys required by the cryptoloop or dm-crypt | |
499 | disk encryption schemes, especially in the case when | |
500 | pkcs11keepstate=yes causes pluto to lock the pkcs11 slot | |
501 | permanently. | |
502 | ||
503 | - if the file /etc/ipsec.secrets is lacking during the startup of | |
504 | pluto then the root-readable file /etc/ipsec.d/private/myKey.der | |
505 | containing a 2048 bit RSA private key and a matching self-signed | |
506 | certificate stored in the file /etc/ipsec.d/certs/selfCert.der | |
507 | is automatically generated by calling the function | |
508 | ||
509 | ipsec scepclient --out pkcs1 --out cert-self | |
510 | ||
511 | scepclient was written by Jan Hutter and Martin Willi, students | |
512 | at the University of Applied Sciences in Rapperswil, Switzerland. | |
513 | ||
514 | ||
515 | strongswan-2.5.4 | |
516 | ---------------- | |
517 | ||
518 | - the current extension of the PKCS#7 framework introduced | |
519 | a parsing error in PKCS#7 wrapped X.509 certificates that are | |
520 | e.g. transmitted by Windows XP when multi-level CAs are used. | |
521 | the parsing syntax has been fixed. | |
522 | ||
523 | - added a patch by Gerald Richter which tolerates multiple occurrences | |
524 | of the ipsec0 interface when using KLIPS. | |
525 | ||
526 | ||
527 | strongswan-2.5.3 | |
528 | ---------------- | |
529 | ||
530 | - with gawk-3.1.4 the word "default2 has become a protected | |
531 | keyword for use in switch statements and cannot be used any | |
532 | more in the strongSwan scripts. This problem has been | |
533 | solved by renaming "default" to "defaults" and "setdefault" | |
534 | in the scripts _confread and auto, respectively. | |
535 | ||
536 | - introduced the parameter leftsendcert with the values | |
537 | ||
538 | always|yes (the default, always send a cert) | |
539 | ifasked (send the cert only upon a cert request) | |
540 | never|no (never send a cert, used for raw RSA keys and | |
541 | self-signed certs) | |
542 | ||
543 | - fixed the initialization of the ESP key length to a default of | |
544 | 128 bits in the case that the peer does not send a key length | |
545 | attribute for AES encryption. | |
546 | ||
547 | - applied Herbert Xu's uniqueIDs patch | |
548 | ||
549 | - applied Herbert Xu's CLOEXEC patches | |
550 | ||
551 | ||
552 | strongswan-2.5.2 | |
553 | ---------------- | |
554 | ||
555 | - CRLs can now be cached also in the case when the issuer's | |
556 | certificate does not contain a subjectKeyIdentifier field. | |
557 | In that case the subjectKeyIdentifier is computed by pluto as the | |
558 | 160 bit SHA-1 hash of the issuer's public key in compliance | |
559 | with section 4.2.1.2 of RFC 3280. | |
560 | ||
561 | - Fixed a bug introduced by strongswan-2.5.1 which eliminated | |
562 | not only multiple Quick Modes of a given connection but also | |
563 | multiple connections between two security gateways. | |
564 | ||
565 | ||
566 | strongswan-2.5.1 | |
567 | ---------------- | |
568 | ||
569 | - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute | |
570 | installed either by setting auto=route in ipsec.conf or by | |
571 | a connection put into hold, generates an XFRM_AQUIRE event | |
572 | for each packet that wants to use the not-yet exisiting | |
573 | tunnel. Up to now each XFRM_AQUIRE event led to an entry in | |
574 | the Quick Mode queue, causing multiple IPsec SA to be | |
575 | established in rapid succession. Starting with strongswan-2.5.1 | |
576 | only a single IPsec SA is established per host-pair connection. | |
577 | ||
578 | - Right after loading the PKCS#11 module, all smartcard slots are | |
579 | searched for certificates. The result can be viewed using | |
580 | the command | |
581 | ||
582 | ipsec auto --listcards | |
583 | ||
584 | The certificate objects found in the slots are numbered | |
585 | starting with #1, #2, etc. This position number can be used to address | |
586 | certificates (leftcert=%smartcard) and keys (: PIN %smartcard) | |
587 | in ipsec.conf and ipsec.secrets, respectively: | |
588 | ||
589 | %smartcard (selects object #1) | |
590 | %smartcard#1 (selects object #1) | |
591 | %smartcard#3 (selects object #3) | |
592 | ||
593 | As an alternative the existing retrieval scheme can be used: | |
594 | ||
595 | %smartcard:45 (selects object with id=45) | |
596 | %smartcard0 (selects first object in slot 0) | |
597 | %smartcard4:45 (selects object in slot 4 with id=45) | |
598 | ||
599 | - Depending on the settings of CKA_SIGN and CKA_DECRYPT | |
600 | private key flags either C_Sign() or C_Decrypt() is used | |
601 | to generate a signature. | |
602 | ||
603 | - The output buffer length parameter siglen in C_Sign() | |
604 | is now initialized to the actual size of the output | |
605 | buffer prior to the function call. This fixes the | |
606 | CKR_BUFFER_TOO_SMALL error that could occur when using | |
607 | the OpenSC PKCS#11 module. | |
608 | ||
609 | - Changed the initialization of the PKCS#11 CK_MECHANISM in | |
610 | C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }. | |
611 | ||
612 | - Refactored the RSA public/private key code and transferred it | |
613 | from keys.c to the new pkcs1.c file as a preparatory step | |
614 | towards the release of the SCEP client. | |
615 | ||
616 | ||
617 | strongswan-2.5.0 | |
618 | ---------------- | |
619 | ||
620 | - The loading of a PKCS#11 smartcard library module during | |
621 | runtime does not require OpenSC library functions any more | |
622 | because the corresponding code has been integrated into | |
623 | smartcard.c. Also the RSAREF pkcs11 header files have been | |
624 | included in a newly created pluto/rsaref directory so that | |
625 | no external include path has to be defined any longer. | |
626 | ||
627 | - A long-awaited feature has been implemented at last: | |
628 | The local caching of CRLs fetched via HTTP or LDAP, activated | |
629 | by the parameter cachecrls=yes in the config setup section | |
630 | of ipsec.conf. The dynamically fetched CRLs are stored under | |
631 | a unique file name containing the issuer's subjectKeyID | |
632 | in /etc/ipsec.d/crls. | |
633 | ||
634 | - Applied a one-line patch courtesy of Michael Richardson | |
635 | from the Openswan project which fixes the kernel-oops | |
636 | in KLIPS when an snmp daemon is running on the same box. | |
637 | ||
638 | ||
639 | strongswan-2.4.4 | |
640 | ---------------- | |
641 | ||
642 | - Eliminated null length CRL distribution point strings. | |
643 | ||
644 | - Fixed a trust path evaluation bug introduced with 2.4.3 | |
645 | ||
646 | ||
647 | strongswan-2.4.3 | |
648 | ---------------- | |
649 | ||
650 | - Improved the joint OCSP / CRL revocation policy. | |
651 | OCSP responses have precedence over CRL entries. | |
652 | ||
653 | - Introduced support of CRLv2 reason codes. | |
654 | ||
655 | - Fixed a bug with key-pad equipped readers which caused | |
656 | pluto to prompt for the pin via the console when the first | |
657 | occasion to enter the pin via the key-pad was missed. | |
658 | ||
659 | - When pluto is built with LDAP_V3 enabled, the library | |
660 | liblber required by newer versions of openldap is now | |
661 | included. | |
662 | ||
663 | ||
664 | strongswan-2.4.2 | |
665 | ---------------- | |
666 | ||
667 | - Added the _updown_espmark template which requires all | |
668 | incoming ESP traffic to be marked with a default mark | |
669 | value of 50. | |
670 | ||
671 | - Introduced the pkcs11keepstate parameter in the config setup | |
672 | section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11 | |
673 | session and login states are kept as long as possible during | |
674 | the lifetime of pluto. This means that a PIN entry via a key | |
675 | pad has to be done only once. | |
676 | ||
677 | - Introduced the pkcs11module parameter in the config setup | |
678 | section of ipsec.conf which specifies the PKCS#11 module | |
679 | to be used with smart cards. Example: | |
680 | ||
681 | pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo | |
682 | ||
683 | - Added support of smartcard readers equipped with a PIN pad. | |
684 | ||
685 | - Added patch by Jay Pfeifer which detects when netkey | |
686 | modules have been statically built into the Linux 2.6 kernel. | |
687 | ||
688 | - Added two patches by Herbert Xu. The first uses ip xfrm | |
689 | instead of setkey to flush the IPsec policy database. The | |
690 | second sets the optional flag in inbound IPComp SAs only. | |
691 | ||
692 | - Applied Ulrich Weber's patch which fixes an interoperability | |
693 | problem between native IPsec and KLIPS systems caused by | |
694 | setting the replay window to 32 instead of 0 for ipcomp. | |
695 | ||
696 | ||
697 | strongswan-2.4.1 | |
698 | ---------------- | |
699 | ||
700 | - Fixed a bug which caused an unwanted Mode Config request | |
701 | to be initiated in the case where "right" was used to denote | |
702 | the local side in ipsec.conf and "left" the remote side, | |
703 | contrary to the recommendation that "right" be remote and | |
704 | "left" be"local". | |
705 | ||
706 | ||
707 | strongswan-2.4.0a | |
708 | ----------------- | |
709 | ||
710 | - updated Vendor ID to strongSwan-2.4.0 | |
711 | ||
712 | - updated copyright statement to include David Buechi and | |
713 | Michael Meier | |
714 | ||
715 | ||
716 | strongswan-2.4.0 | |
717 | ---------------- | |
718 | ||
719 | - strongSwan now communicates with attached smartcards and | |
720 | USB crypto tokens via the standardized PKCS #11 interface. | |
721 | By default the OpenSC library from www.opensc.org is used | |
722 | but any other PKCS#11 library could be dynamically linked. | |
723 | strongSwan's PKCS#11 API was implemented by David Buechi | |
724 | and Michael Meier, both graduates of the Zurich University | |
725 | of Applied Sciences in Winterthur, Switzerland. | |
726 | ||
727 | - When a %trap eroute is triggered by an outgoing IP packet | |
728 | then the native IPsec stack of the Linux 2.6 kernel [often/ | |
729 | always?] returns an XFRM_ACQUIRE message with an undefined | |
730 | protocol family field and the connection setup fails. | |
731 | As a workaround IPv4 (AF_INET) is now assumed. | |
732 | ||
733 | - the results of the UML test scenarios are now enhanced | |
734 | with block diagrams of the virtual network topology used | |
735 | in a particular test. | |
736 | ||
737 | ||
738 | strongswan-2.3.2 | |
739 | ---------------- | |
740 | ||
741 | - fixed IV used to decrypt informational messages. | |
742 | This bug was introduced with Mode Config functionality. | |
743 | ||
744 | - fixed NCP Vendor ID. | |
745 | ||
746 | - undid one of Ulrich Weber's maximum udp size patches | |
747 | because it caused a segmentation fault with NAT-ed | |
748 | Delete SA messages. | |
749 | ||
750 | - added UML scenarios wildcards and attr-cert which | |
751 | demonstrate the implementation of IPsec policies based | |
752 | on wildcard parameters contained in Distinguished Names and | |
753 | on X.509 attribute certificates, respectively. | |
754 | ||
755 | ||
756 | strongswan-2.3.1 | |
757 | ---------------- | |
758 | ||
759 | - Added basic Mode Config functionality | |
760 | ||
761 | - Added Mathieu Lafon's patch which upgrades the status of | |
762 | the NAT-Traversal implementation to RFC 3947. | |
763 | ||
764 | - The _startklips script now also loads the xfrm4_tunnel | |
765 | module. | |
766 | ||
767 | - Added Ulrich Weber's netlink replay window size and | |
768 | maximum udp size patches. | |
769 | ||
770 | - UML testing now uses the Linux 2.6.10 UML kernel by default. | |
771 | ||
772 | ||
773 | strongswan-2.3.0 | |
774 | ---------------- | |
775 | ||
776 | - Eric Marchionni and Patrik Rayo, both recent graduates from | |
777 | the Zuercher Hochschule Winterthur in Switzerland, created a | |
778 | User-Mode-Linux test setup for strongSwan. For more details | |
779 | please read the INSTALL and README documents in the testing | |
780 | subdirectory. | |
781 | ||
782 | - Full support of group attributes based on X.509 attribute | |
783 | certificates. Attribute certificates can be generated | |
784 | using the openac facility. For more details see | |
785 | ||
786 | man ipsec_openac. | |
787 | ||
788 | The group attributes can be used in connection definitions | |
789 | in order to give IPsec access to specific user groups. | |
790 | This is done with the new parameter left|rightgroups as in | |
791 | ||
792 | rightgroups="Research, Sales" | |
793 | ||
794 | giving access to users possessing the group attributes | |
795 | Research or Sales, only. | |
796 | ||
797 | - In Quick Mode clients with subnet mask /32 are now | |
798 | coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should | |
799 | fix rekeying problems with the SafeNet/SoftRemote and NCP | |
800 | Secure Entry Clients. | |
801 | ||
802 | - Changed the defaults of the ikelifetime and keylife parameters | |
803 | to 3h and 1h, respectively. The maximum allowable values are | |
804 | now both set to 24 h. | |
805 | ||
806 | - Suppressed notification wars between two IPsec peers that | |
807 | could e.g. be triggered by incorrect ISAKMP encryption. | |
808 | ||
809 | - Public RSA keys can now have identical IDs if either the | |
810 | issuing CA or the serial number is different. The serial | |
811 | number of a certificate is now shown by the command | |
812 | ||
813 | ipsec auto --listpubkeys | |
814 | ||
815 | ||
816 | strongswan-2.2.2 | |
817 | ---------------- | |
818 | ||
819 | - Added Tuomo Soini's sourceip feature which allows a strongSwan | |
820 | roadwarrior to use a fixed Virtual IP (see README section 2.6) | |
821 | and reduces the well-known four tunnel case on VPN gateways to | |
822 | a single tunnel definition (see README section 2.4). | |
823 | ||
824 | - Fixed a bug occuring with NAT-Traversal enabled when the responder | |
825 | suddenly turns initiator and the initiator cannot find a matching | |
826 | connection because of the floated IKE port 4500. | |
827 | ||
828 | - Removed misleading ipsec verify command from barf. | |
829 | ||
830 | - Running under the native IP stack, ipsec --version now shows | |
831 | the Linux kernel version (courtesy to the Openswan project). | |
832 | ||
833 | ||
834 | strongswan-2.2.1 | |
835 | ---------------- | |
836 | ||
837 | - Introduced the ipsec auto --listalgs monitoring command which lists | |
838 | all currently registered IKE and ESP algorithms. | |
839 | ||
840 | - Fixed a bug in the ESP algorithm selection occuring when the strict flag | |
841 | is set and the first proposed transform does not match. | |
842 | ||
843 | - Fixed another deadlock in the use of the lock_certs_and_keys() mutex, | |
844 | occuring when a smartcard is present. | |
845 | ||
846 | - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event. | |
847 | ||
848 | - Fixed the printing of the notification names (null) | |
849 | ||
850 | - Applied another of Herbert Xu's Netlink patches. | |
851 | ||
852 | ||
853 | strongswan-2.2.0 | |
854 | ---------------- | |
855 | ||
856 | - Support of Dead Peer Detection. The connection parameter | |
857 | ||
858 | dpdaction=clear|hold | |
859 | ||
860 | activates DPD for the given connection. | |
861 | ||
862 | - The default Opportunistic Encryption (OE) policy groups are not | |
863 | automatically included anymore. Those wishing to activate OE can include | |
864 | the policy group with the following statement in ipsec.conf: | |
865 | ||
866 | include /etc/ipsec.d/examples/oe.conf | |
867 | ||
868 | The default for [right|left]rsasigkey is now set to %cert. | |
869 | ||
870 | - strongSwan now has a Vendor ID of its own which can be activated | |
871 | using the compile option VENDORID | |
872 | ||
873 | - Applied Herbert Xu's patch which sets the compression algorithm correctly. | |
874 | ||
875 | - Applied Herbert Xu's patch fixing an ESPINUDP problem | |
876 | ||
877 | - Applied Herbert Xu's patch setting source/destination port numbers. | |
878 | ||
879 | - Reapplied one of Herbert Xu's NAT-Traversal patches which got | |
880 | lost during the migration from SuperFreeS/WAN. | |
881 | ||
882 | - Fixed a deadlock in the use of the lock_certs_and_keys() mutex. | |
883 | ||
884 | - Fixed the unsharing of alg parameters when instantiating group | |
885 | connection. | |
886 | ||
887 | ||
888 | strongswan-2.1.5 | |
889 | ---------------- | |
890 | ||
891 | - Thomas Walpuski made me aware of a potential DoS attack via | |
892 | a PKCS#7-wrapped certificate bundle which could overwrite valid CA | |
893 | certificates in Pluto's authority certificate store. This vulnerability | |
894 | was fixed by establishing trust in CA candidate certificates up to a | |
895 | trusted root CA prior to insertion into Pluto's chained list. | |
896 | ||
897 | - replaced the --assign option by the -v option in the auto awk script | |
898 | in order to make it run with mawk under debian/woody. | |
899 | ||
900 | ||
901 | strongswan-2.1.4 | |
902 | ---------------- | |
903 | ||
904 | - Split of the status information between ipsec auto --status (concise) | |
905 | and ipsec auto --statusall (verbose). Both commands can be used with | |
906 | an optional connection selector: | |
907 | ||
908 | ipsec auto --status[all] <connection_name> | |
909 | ||
910 | - Added the description of X.509 related features to the ipsec_auto(8) | |
911 | man page. | |
912 | ||
913 | - Hardened the ASN.1 parser in debug mode, especially the printing | |
914 | of malformed distinguished names. | |
915 | ||
916 | - The size of an RSA public key received in a certificate is now restricted to | |
917 | ||
918 | 512 bits <= modulus length <= 8192 bits. | |
919 | ||
920 | - Fixed the debug mode enumeration. | |
921 | ||
922 | ||
923 | strongswan-2.1.3 | |
924 | ---------------- | |
925 | ||
926 | - Fixed another PKCS#7 vulnerability which could lead to an | |
927 | endless loop while following the X.509 trust chain. | |
928 | ||
929 | ||
930 | strongswan-2.1.2 | |
931 | ---------------- | |
932 | ||
933 | - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski | |
934 | that accepted end certificates having identical issuer and subject | |
935 | distinguished names in a multi-tier X.509 trust chain. | |
936 | ||
937 | ||
938 | strongswan-2.1.1 | |
939 | ---------------- | |
940 | ||
941 | - Removed all remaining references to ipsec_netlink.h in KLIPS. | |
942 | ||
943 | ||
944 | strongswan-2.1.0 | |
945 | ---------------- | |
946 | ||
947 | - The new "ca" section allows to define the following parameters: | |
948 | ||
949 | ca kool | |
950 | cacert=koolCA.pem # cacert of kool CA | |
951 | ocspuri=http://ocsp.kool.net:8001 # ocsp server | |
952 | ldapserver=ldap.kool.net # default ldap server | |
953 | crluri=http://www.kool.net/kool.crl # crl distribution point | |
954 | crluri2="ldap:///O=Kool, C= .." # crl distribution point #2 | |
955 | auto=add # add, ignore | |
956 | ||
957 | The ca definitions can be monitored via the command | |
958 | ||
959 | ipsec auto --listcainfos | |
960 | ||
961 | - Fixed cosmetic corruption of /proc filesystem by integrating | |
962 | D. Hugh Redelmeier's freeswan-2.06 kernel fixes. | |

965 | strongswan-2.0.2 | |
966 | ---------------- | |
967 | ||
968 | - Added support for the 818043 NAT-Traversal update of Microsoft's | |
969 | Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode. | |
970 | ||
971 | - A symbolic link to libcrypto is now added in the kernel sources | |
972 | during kernel compilation | |
973 | ||
974 | - Fixed a couple of 64 bit issues (mostly casts to int). | |
975 | Thanks to Ken Bantoft who checked my sources on a 64 bit platform. | |
976 | ||
977 | - Replaced s[n]printf() statements in the kernel by ipsec_snprintf(). | |
978 | Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro | |
979 | of the FreeS/WAN team who solved this problem with the 2.4.25 kernel. | |

982 | strongswan-2.0.1 | |
983 | ---------------- | |
984 | ||
985 | - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName | |
986 | certificate extension which contains no generalName item) can cause | |
987 | a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has | |
988 | been hardened to make it more robust against malformed ASN.1 objects. | |
989 | ||
990 | - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native | |
991 | Linux 2.6 IPsec stack. | |
