1 | strongswan-4.1.1 |
2 | ---------------- | |
3 | ||
4 | - Server side cookie support. If to may IKE_SAs are in CONNECTING state, | |
5 | cookies are enabled and protect against DoS attacks with faked source | |
6 | addresses. Number of IKE_SAs in CONNECTING state is also limited per | |
7 | peer address to avoid resource exhaustion. IKE_SA_INIT messages are | |
8 | compared to properly detect retransmissions and incoming retransmits are | |
9 | detected even if the IKE_SA is blocked (e.g. doing OCSP fetches). | |
10 | ||
3b4f7d92 AS |
11 | - Added the configuration options --enable-nat-transport which enables |
12 | the potentially insecure NAT traversal for IPsec transport mode and | |
13 | --disable-vendor-id which disables the sending of the strongSwan | |
14 | vendor ID. | |
15 | ||
16 | - Fixed a long-standing bug in the pluto IKEv1 daemon which caused | |
17 | a segmentation fault if a malformed payload was detected in the | |
18 | IKE MR2 message and pluto tried to send an encrypted notification | |
19 | message. | |
20 | ||
8f76dbe8 AS |
21 | - The IKEv2 daemon charon now supports dynamic http-based CRL fetching. |
22 | ||
3b4f7d92 | 23 | |
34bbd0c3 | 24 | strongswan-4.1.0 |
cd3958f8 AS |
25 | ---------------- |
26 | ||
27 | - Support of SHA2_384 hash function for protecting IKEv1 | |
28 | negotiations and support of SHA2 signatures in X.509 certificates. | |
29 | ||
30 | - Fixed a serious bug in the computation of the SHA2-512 HMAC | |
31 | function. Introduced automatic self-test of all IKEv1 hash | |
32 | and hmac functions during pluto startup. Failure of a self-test | |
33 | currently issues a warning only but does not exit pluto [yet]. | |
34 | ||
9b45443d MW |
35 | - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2. |
36 | ||
c5d0fbb6 AS |
37 | - Full support of CA information sections. ipsec listcainfos |
38 | now shows all collected crlDistributionPoints and OCSP | |
39 | accessLocations. | |
40 | ||
69ed04bf AS |
41 | - Support of the Online Certificate Status Protocol (OCSP) for IKEv2. |
42 | This feature requires the HTTP fetching capabilities of the libcurl | |
43 | library which must be enabled by setting the --enable-http configure | |
44 | option. | |
45 | ||
9b45443d MW |
46 | - Refactored core of the IKEv2 message processing code, allowing better |
47 | code reuse and separation. | |
48 | ||
49 | - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration | |
50 | payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted | |
51 | by the requestor and installed in a resolv.conf file. | |
52 | ||
53 | - The IKEv2 daemon charon installs a route for each IPsec policy to use | |
54 | the correct source address even if an application does not explicitly | |
55 | specify it. | |
56 | ||
57 | - Integrated the EAP framework into charon which loads pluggable EAP library | |
58 | modules. The ipsec.conf parameter authby=eap initiates EAP authentication | |
59 | on the client side, while the "eap" parameter on the server side defines | |
60 | the EAP method to use for client authentication. | |
61 | A generic client side EAP-Identity module and an EAP-SIM authentication | |
62 | module using a third party card reader implementation are included. | |
63 | ||
64 | - Added client side support for cookies. | |
65 | ||
66 | - Integrated the fixes done at the IKEv2 interoperability bakeoff, including | |
67 | strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor | |
68 | fixes to enhance interoperability with other implementations. | |

1c266d7d AS |
70 | strongswan-4.0.7 |
71 | ---------------- | |
72 | ||
6fdf5f44 AS |
73 | - strongSwan now interoperates with the NCP Secure Entry Client, |
74 | the Shrew Soft VPN Client, and the Cisco VPN client, doing both | |
75 | XAUTH and Mode Config. | |
1c266d7d AS |
76 | |
77 | - UNITY attributes are now recognized and UNITY_BANNER is set | |
78 | to a default string. | |
79 | ||
80 | ||
2b4405a3 MW |
81 | strongswan-4.0.6 |
82 | ---------------- | |
83 | ||
e38a15d4 AS |
84 | - IKEv1: Support for extended authentication (XAUTH) in combination |
85 | with ISAKMP Main Mode RSA or PSK authentication. Both client and | |
86 | server side were implemented. Handling of user credentials can | |
87 | be done by a run-time loadable XAUTH module. By default user | |
88 | credentials are stored in ipsec.secrets. | |
89 | ||
2b4405a3 MW |
90 | - IKEv2: Support for reauthentication when rekeying |
91 | ||
5903179b | 92 | - IKEv2: Support for transport mode |
af87afed | 93 | |
5903179b | 94 | - fixed a lot of bugs related to byte order |
2b4405a3 | 95 | |
5903179b | 96 | - various other bugfixes |
2b4405a3 MW |
97 | |
98 | ||
0cd645d2 AS |
99 | strongswan-4.0.5 |
100 | ---------------- | |
101 | ||
102 | - IKEv1: Implementation of ModeConfig push mode via the new connection | |
103 | keyword modeconfig=push allows interoperability with Cisco VPN gateways. | |
104 | ||
105 | - IKEv1: The command ipsec statusall now shows "DPD active" for all | |
106 | ISAKMP SAs that are under active Dead Peer Detection control. | |
107 | ||
108 | - IKEv2: Charon's logging and debugging framework has been completely rewritten. | |
109 | Instead of logger, special printf() functions are used to directly | |
110 | print objects like hosts (%H) identifications (%D), certificates (%Q), | |
111 | etc. The number of debugging levels have been reduced to: | |
03bf883d | 112 | |
0cd645d2 | 113 | 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private) |
03bf883d | 114 | |
0cd645d2 AS |
115 | The debugging levels can either be specified statically in ipsec.conf as |
116 | ||
117 | config setup | |
03bf883d | 118 | charondebug="lib 1, cfg 3, net 2" |
0cd645d2 | 119 | |
03bf883d | 120 | or changed at runtime via stroke as |
0cd645d2 | 121 | |
03bf883d | 122 | ipsec stroke loglevel cfg 2 |
0cd645d2 AS |

48dc3934 MW |
125 | strongswan-4.0.4 |
126 | ---------------- | |
127 | ||
128 | - Implemented full support for IPv6-in-IPv6 tunnels. | |
129 | ||
130 | - Added configuration options for dead peer detection in IKEv2. dpd_action | |
131 | types "clear", "hold" and "restart" are supported. The dpd_timeout | |
132 | value is not used, as the normal retransmission policy applies to | |
133 | detect dead peers. The dpd_delay parameter enables sending of empty | |
134 | informational message to detect dead peers in case of inactivity. | |
135 | ||
136 | - Added support for preshared keys in IKEv2. PSK keys configured in | |
137 | ipsec.secrets are loaded. The authby parameter specifies the authentication | |
138 | method to authentificate ourself, the other peer may use PSK or RSA. | |
139 | ||
140 | - Changed retransmission policy to respect the keyingtries parameter. | |
141 | ||
112ad7c3 AS |
142 | - Added private key decryption. PEM keys encrypted with AES-128/192/256 |
143 | or 3DES are supported. | |
48dc3934 MW |
144 | |
145 | - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to | |
146 | encrypt IKE traffic. | |
147 | ||
148 | - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates | |
149 | signed with such a hash algorithm. | |
150 | ||
151 | - Added initial support for updown scripts. The actions up-host/client and | |
152 | down-host/client are executed. The leftfirewall=yes parameter | |
153 | uses the default updown script to insert dynamic firewall rules, a custom | |
154 | updown script may be specified with the leftupdown parameter. | |
155 | ||
156 | ||
a1310b6b MW |
157 | strongswan-4.0.3 |
158 | ---------------- | |
159 | ||
160 | - Added support for the auto=route ipsec.conf parameter and the | |
161 | ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and | |
162 | CHILD_SAs dynamically on demand when traffic is detected by the | |
163 | kernel. | |
164 | ||
165 | - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter. | |
166 | As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only | |
167 | new keys are generated using perfect forward secrecy. An optional flag | |
168 | which enforces reauthentication will be implemented later. | |
169 | ||
b425d998 AS |
170 | - "sha" and "sha1" are now treated as synonyms in the ike= and esp= |
171 | algorithm configuration statements. | |
172 | ||
173 | ||
bf4df11f AS |
174 | strongswan-4.0.2 |
175 | ---------------- | |
176 | ||
623d3dcf AS |
177 | - Full X.509 certificate trust chain verification has been implemented. |
178 | End entity certificates can be exchanged via CERT payloads. The current | |
179 | default is leftsendcert=always, since CERTREQ payloads are not supported | |
180 | yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls. | |
efa40c11 MW |
181 | |
182 | - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2 | |
183 | would offer more possibilities for traffic selection, but the Linux kernel | |
184 | currently does not support it. That's why we stick with these simple | |
185 | ipsec.conf rules for now. | |
186 | ||
623d3dcf AS |
187 | - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no |
188 | IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear, | |
189 | dpddelay=60s). | |
190 | ||
efa40c11 MW |
191 | - Initial NAT traversal support in IKEv2. Charon includes NAT detection |
192 | notify payloads to detect NAT routers between the peers. It switches | |
193 | to port 4500, uses UDP encapsulated ESP packets, handles peer address | |
194 | changes gracefully and sends keep alive message periodically. | |
195 | ||
196 | - Reimplemented IKE_SA state machine for charon, which allows simultaneous | |
197 | rekeying, more shared code, cleaner design, proper retransmission | |
198 | and a more extensible code base. | |
199 | ||
cfd8b27f AS |
200 | - The mixed PSK/RSA roadwarrior detection capability introduced by the |
201 | strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal | |
202 | payloads by the responder right before any defined IKE Main Mode state had | |
203 | been established. Although any form of bad proposal syntax was being correctly | |
204 | detected by the payload parser, the subsequent error handler didn't check | |
205 | the state pointer before logging current state information, causing an | |
206 | immediate crash of the pluto keying daemon due to a NULL pointer. | |
207 | ||

209 | strongswan-4.0.1 |
210 | ---------------- | |
211 | ||
c15c3d4b MW |
212 | - Added algorithm selection to charon: New default algorithms for |
213 | ike=aes128-sha-modp2048, as both daemons support it. The default | |
214 | for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles | |
215 | the ike/esp parameter the same way as pluto. As this syntax does | |
216 | not allow specification of a pseudo random function, the same | |
217 | algorithm as for integrity is used (currently sha/md5). Supported | |
218 | algorithms for IKE: | |
219 | Encryption: aes128, aes192, aes256 | |
220 | Integrity/PRF: md5, sha (using hmac) | |
221 | DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192 | |
222 | and for ESP: | |
223 | Encryption: aes128, aes192, aes256, 3des, blowfish128, | |
224 | blowfish192, blowfish256 | |
225 | Integrity: md5, sha1 | |
226 | More IKE encryption algorithms will come after porting libcrypto into | |
227 | libstrongswan. | |
f2c2d395 | 228 | |
c15c3d4b MW |
229 | - initial support for rekeying CHILD_SAs using IKEv2. Currently no |
230 | perfect forward secrecy is used. The rekeying parameters rekey, | |
22ff6f57 | 231 | rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported |
c15c3d4b MW |
232 | when using IKEv2. WARNING: charon currently is unable to handle |
233 | simultaneous rekeying. To avoid such a situation, use a large | |
234 | rekeyfuzz, or even better, set rekey=no on one peer. | |
22ff6f57 | 235 | |
7e81e975 MW |
236 | - support for host2host, net2net, host2net (roadwarrior) tunnels |
237 | using predefined RSA certificates (see uml scenarios for | |
238 | configuration examples). | |
239 | ||
f2c2d395 MW |
240 | - new build environment featuring autotools. Features such |
241 | as HTTP, LDAP and smartcard support may be enabled using | |
242 | the ./configure script. Changing install directories | |
243 | is possible, too. See ./configure --help for more details. | |
244 | ||
22ff6f57 MW |
245 | - better integration of charon with ipsec starter, which allows |
246 | (almost) transparent operation with both daemons. charon | |
247 | handles ipsec commands up, down, status, statusall, listall, | |
248 | listcerts and allows proper load, reload and delete of connections | |
249 | via ipsec starter. | |
250 | ||
b425d998 | 251 | |
9820c0e2 MW |
252 | strongswan-4.0.0 |
253 | ---------------- | |
254 | ||
255 | - initial support of the IKEv2 protocol. Connections in | |
256 | ipsec.conf designated by keyexchange=ikev2 are negotiated | |
257 | by the new IKEv2 charon keying daemon whereas those marked | |
258 | by keyexchange=ikev1 or the default keyexchange=ike are | |
259 | handled thy the IKEv1 pluto keying daemon. Currently only | |
260 | a limited subset of functions are available with IKEv2 | |
261 | (Default AES encryption, authentication based on locally | |
262 | imported X.509 certificates, unencrypted private RSA keys | |
263 | in PKCS#1 file format, limited functionality of the ipsec | |
264 | status command). | |
265 | ||
266 | ||
997358a6 MW |
267 | strongswan-2.7.0 |
268 | ---------------- | |
269 | ||
270 | - the dynamic iptables rules from the _updown_x509 template | |
271 | for KLIPS and the _updown_policy template for NETKEY have | |
272 | been merged into the default _updown script. The existing | |
273 | left|rightfirewall keyword causes the automatic insertion | |
274 | and deletion of ACCEPT rules for tunneled traffic upon | |
275 | the successful setup and teardown of an IPsec SA, respectively. | |
276 | left|rightfirwall can be used with KLIPS under any Linux 2.4 | |
277 | kernel or with NETKEY under a Linux kernel version >= 2.6.16 | |
278 | in conjuction with iptables >= 1.3.5. For NETKEY under a Linux | |
279 | kernel version < 2.6.16 which does not support IPsec policy | |
280 | matching yet, please continue to use a copy of the _updown_espmark | |
281 | template loaded via the left|rightupdown keyword. | |
282 | ||
283 | - a new left|righthostaccess keyword has been introduced which | |
284 | can be used in conjunction with left|rightfirewall and the | |
285 | default _updown script. By default leftfirewall=yes inserts | |
286 | a bi-directional iptables FORWARD rule for a local client network | |
287 | with a netmask different from 255.255.255.255 (single host). | |
288 | This does not allow to access the VPN gateway host via its | |
289 | internal network interface which is part of the client subnet | |
290 | because an iptables INPUT and OUTPUT rule would be required. | |
291 | lefthostaccess=yes will cause this additional ACCEPT rules to | |
292 | be inserted. | |
293 | ||
294 | - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal | |
295 | payload is preparsed in order to find out whether the roadwarrior | |
296 | requests PSK or RSA so that a matching connection candidate can | |
297 | be found. | |
298 | ||
299 | ||
300 | strongswan-2.6.4 | |
301 | ---------------- | |
302 | ||
303 | - the new _updown_policy template allows ipsec policy based | |
304 | iptables firewall rules. Required are iptables version | |
305 | >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes | |
306 | the _updown_espmark template, so that no INPUT mangle rules | |
307 | are required any more. | |
308 | ||
309 | - added support of DPD restart mode | |
310 | ||
311 | - ipsec starter now allows the use of wildcards in include | |
312 | statements as e.g. in "include /etc/my_ipsec/*.conf". | |
313 | Patch courtesy of Matthias Haas. | |
314 | ||
315 | - the Netscape OID 'employeeNumber' is now recognized and can be | |
316 | used as a Relative Distinguished Name in certificates. | |
317 | ||
318 | ||
319 | strongswan-2.6.3 | |
320 | ---------------- | |
321 | ||
322 | - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec | |
323 | command and not of ipsec setup any more. | |
324 | ||
325 | - ipsec starter now supports AH authentication in conjunction with | |
326 | ESP encryption. AH authentication is configured in ipsec.conf | |
327 | via the auth=ah parameter. | |
328 | ||
329 | - The command ipsec scencrypt|scdecrypt <args> is now an alias for | |
330 | ipsec whack --scencrypt|scdecrypt <args>. | |
331 | ||
332 | - get_sa_info() now determines for the native netkey IPsec stack | |
333 | the exact time of the last use of an active eroute. This information | |
334 | is used by the Dead Peer Detection algorithm and is also displayed by | |
335 | the ipsec status command. | |
336 | ||
337 | ||
338 | strongswan-2.6.2 | |
339 | ---------------- | |
340 | ||
341 | - running under the native Linux 2.6 IPsec stack, the function | |
342 | get_sa_info() is called by ipsec auto --status to display the current | |
343 | number of transmitted bytes per IPsec SA. | |
344 | ||
345 | - get_sa_info() is also used by the Dead Peer Detection process to detect | |
346 | recent ESP activity. If ESP traffic was received from the peer within | |
347 | the last dpd_delay interval then no R_Y_THERE notification must be sent. | |
348 | ||
349 | - strongSwan now supports the Relative Distinguished Name "unstructuredName" | |
350 | in ID_DER_ASN1_DN identities. The following notations are possible: | |
351 | ||
352 | rightid="unstructuredName=John Doe" | |
353 | rightid="UN=John Doe" | |
354 | ||
355 | - fixed a long-standing bug which caused PSK-based roadwarrior connections | |
356 | to segfault in the function id.c:same_id() called by keys.c:get_secret() | |
357 | if an FQDN, USER_FQDN, or Key ID was defined, as in the following example. | |
358 | ||
359 | conn rw | |
360 | right=%any | |
361 | rightid=@foo.bar | |
362 | authby=secret | |
363 | ||
364 | - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall). | |
365 | ||
366 | - ipsec starter didn't set host_addr and client.addr ports in whack msg. | |
367 | ||
368 | - in order to guarantee backwards-compatibility with the script-based | |
369 | auto function (e.g. auto --replace), the ipsec starter scripts stores | |
370 | the defaultroute information in the temporary file /var/run/ipsec.info. | |
371 | ||
372 | - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH | |
373 | Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config | |
374 | servers. | |
375 | ||
376 | - the ipsec starter now also recognizes the parameters authby=never and | |
377 | type=passthrough|pass|drop|reject. | |
378 | ||
379 | ||
380 | strongswan-2.6.1 | |
381 | ---------------- | |
382 | ||
383 | - ipsec starter now supports the also parameter which allows | |
384 | a modular structure of the connection definitions. Thus | |
385 | "ipsec start" is now ready to replace "ipsec setup". | |
386 | ||
387 | ||
388 | strongswan-2.6.0 | |
389 | ---------------- | |
390 | ||
391 | - Mathieu Lafon's popular ipsec starter tool has been added to the | |
392 | strongSwan distribution. Many thanks go to Stephan Scholz from astaro | |
393 | for his integration work. ipsec starter is a C program which is going | |
394 | to replace the various shell and awk starter scripts (setup, _plutoload, | |
395 | _plutostart, _realsetup, _startklips, _confread, and auto). Since | |
396 | ipsec.conf is now parsed only once, the starting of multiple tunnels is | |
397 | accelerated tremedously. | |
398 | ||
399 | - Added support of %defaultroute to the ipsec starter. If the IP address | |
400 | changes, a HUP signal to the ipsec starter will automatically | |
401 | reload pluto's connections. | |
402 | ||
403 | - moved most compile time configurations from pluto/Makefile to | |
404 | Makefile.inc by defining the options USE_LIBCURL, USE_LDAP, | |
405 | USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE. | |
406 | ||
407 | - removed the ipsec verify and ipsec newhostkey commands | |
408 | ||
409 | - fixed some 64-bit issues in formatted print statements | |
410 | ||
411 | - The scepclient functionality implementing the Simple Certificate | |
412 | Enrollment Protocol (SCEP) is nearly complete but hasn't been | |
413 | documented yet. | |
414 | ||
415 | ||
416 | strongswan-2.5.7 | |
417 | ---------------- | |
418 | ||
419 | - CA certicates are now automatically loaded from a smartcard | |
420 | or USB crypto token and appear in the ipsec auto --listcacerts | |
421 | listing. | |
422 | ||
423 | ||
424 | strongswan-2.5.6 | |
425 | ---------------- | |
426 | ||
427 | - when using "ipsec whack --scencrypt <data>" with a PKCS#11 | |
428 | library that does not support the C_Encrypt() Cryptoki | |
429 | function (e.g. OpenSC), the RSA encryption is done in | |
430 | software using the public key fetched from the smartcard. | |
431 | ||
432 | - The scepclient function now allows to define the | |
433 | validity of a self-signed certificate using the --days, | |
434 | --startdate, and --enddate options. The default validity | |
435 | has been changed from one year to five years. | |
436 | ||
437 | ||
438 | strongswan-2.5.5 | |
439 | ---------------- | |
440 | ||
441 | - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11 | |
442 | interface to other applications for RSA encryption and decryption | |
443 | via the whack interface. Notation: | |
444 | ||
445 | ipsec whack --scencrypt <data> | |
446 | [--inbase 16|hex|64|base64|256|text|ascii] | |
447 | [--outbase 16|hex|64|base64|256|text|ascii] | |
448 | [--keyid <keyid>] | |
449 | ||
450 | ipsec whack --scdecrypt <data> | |
451 | [--inbase 16|hex|64|base64|256|text|ascii] | |
452 | [--outbase 16|hex|64|base64|256|text|ascii] | |
453 | [--keyid <keyid>] | |
454 | ||
455 | The default setting for inbase and outbase is hex. | |
456 | ||
457 | The new proxy interface can be used for securing symmetric | |
458 | encryption keys required by the cryptoloop or dm-crypt | |
459 | disk encryption schemes, especially in the case when | |
460 | pkcs11keepstate=yes causes pluto to lock the pkcs11 slot | |
461 | permanently. | |
462 | ||
463 | - if the file /etc/ipsec.secrets is lacking during the startup of | |
464 | pluto then the root-readable file /etc/ipsec.d/private/myKey.der | |
465 | containing a 2048 bit RSA private key and a matching self-signed | |
466 | certificate stored in the file /etc/ipsec.d/certs/selfCert.der | |
467 | is automatically generated by calling the function | |
468 | ||
469 | ipsec scepclient --out pkcs1 --out cert-self | |
470 | ||
471 | scepclient was written by Jan Hutter and Martin Willi, students | |
472 | at the University of Applied Sciences in Rapperswil, Switzerland. | |
473 | ||
474 | ||
475 | strongswan-2.5.4 | |
476 | ---------------- | |
477 | ||
478 | - the current extension of the PKCS#7 framework introduced | |
479 | a parsing error in PKCS#7 wrapped X.509 certificates that are | |
480 | e.g. transmitted by Windows XP when multi-level CAs are used. | |
481 | the parsing syntax has been fixed. | |
482 | ||
483 | - added a patch by Gerald Richter which tolerates multiple occurrences | |
484 | of the ipsec0 interface when using KLIPS. | |
485 | ||
486 | ||
487 | strongswan-2.5.3 | |
488 | ---------------- | |
489 | ||
490 | - with gawk-3.1.4 the word "default2 has become a protected | |
491 | keyword for use in switch statements and cannot be used any | |
492 | more in the strongSwan scripts. This problem has been | |
493 | solved by renaming "default" to "defaults" and "setdefault" | |
494 | in the scripts _confread and auto, respectively. | |
495 | ||
496 | - introduced the parameter leftsendcert with the values | |
497 | ||
498 | always|yes (the default, always send a cert) | |
499 | ifasked (send the cert only upon a cert request) | |
500 | never|no (never send a cert, used for raw RSA keys and | |
501 | self-signed certs) | |
502 | ||
503 | - fixed the initialization of the ESP key length to a default of | |
504 | 128 bits in the case that the peer does not send a key length | |
505 | attribute for AES encryption. | |
506 | ||
507 | - applied Herbert Xu's uniqueIDs patch | |
508 | ||
509 | - applied Herbert Xu's CLOEXEC patches | |
510 | ||
511 | ||
512 | strongswan-2.5.2 | |
513 | ---------------- | |
514 | ||
515 | - CRLs can now be cached also in the case when the issuer's | |
516 | certificate does not contain a subjectKeyIdentifier field. | |
517 | In that case the subjectKeyIdentifier is computed by pluto as the | |
518 | 160 bit SHA-1 hash of the issuer's public key in compliance | |
519 | with section 4.2.1.2 of RFC 3280. | |
520 | ||
521 | - Fixed a bug introduced by strongswan-2.5.1 which eliminated | |
522 | not only multiple Quick Modes of a given connection but also | |
523 | multiple connections between two security gateways. | |
524 | ||
525 | ||
526 | strongswan-2.5.1 | |
527 | ---------------- | |
528 | ||
529 | - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute | |
530 | installed either by setting auto=route in ipsec.conf or by | |
531 | a connection put into hold, generates an XFRM_AQUIRE event | |
532 | for each packet that wants to use the not-yet exisiting | |
533 | tunnel. Up to now each XFRM_AQUIRE event led to an entry in | |
534 | the Quick Mode queue, causing multiple IPsec SA to be | |
535 | established in rapid succession. Starting with strongswan-2.5.1 | |
536 | only a single IPsec SA is established per host-pair connection. | |
537 | ||
538 | - Right after loading the PKCS#11 module, all smartcard slots are | |
539 | searched for certificates. The result can be viewed using | |
540 | the command | |
541 | ||
542 | ipsec auto --listcards | |
543 | ||
544 | The certificate objects found in the slots are numbered | |
545 | starting with #1, #2, etc. This position number can be used to address | |
546 | certificates (leftcert=%smartcard) and keys (: PIN %smartcard) | |
547 | in ipsec.conf and ipsec.secrets, respectively: | |
548 | ||
549 | %smartcard (selects object #1) | |
550 | %smartcard#1 (selects object #1) | |
551 | %smartcard#3 (selects object #3) | |
552 | ||
553 | As an alternative the existing retrieval scheme can be used: | |
554 | ||
555 | %smartcard:45 (selects object with id=45) | |
556 | %smartcard0 (selects first object in slot 0) | |
557 | %smartcard4:45 (selects object in slot 4 with id=45) | |
558 | ||
559 | - Depending on the settings of CKA_SIGN and CKA_DECRYPT | |
560 | private key flags either C_Sign() or C_Decrypt() is used | |
561 | to generate a signature. | |
562 | ||
563 | - The output buffer length parameter siglen in C_Sign() | |
564 | is now initialized to the actual size of the output | |
565 | buffer prior to the function call. This fixes the | |
566 | CKR_BUFFER_TOO_SMALL error that could occur when using | |
567 | the OpenSC PKCS#11 module. | |
568 | ||
569 | - Changed the initialization of the PKCS#11 CK_MECHANISM in | |
570 | C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }. | |
571 | ||
572 | - Refactored the RSA public/private key code and transferred it | |
573 | from keys.c to the new pkcs1.c file as a preparatory step | |
574 | towards the release of the SCEP client. | |
575 | ||
576 | ||
577 | strongswan-2.5.0 | |
578 | ---------------- | |
579 | ||
580 | - The loading of a PKCS#11 smartcard library module during | |
581 | runtime does not require OpenSC library functions any more | |
582 | because the corresponding code has been integrated into | |
583 | smartcard.c. Also the RSAREF pkcs11 header files have been | |
584 | included in a newly created pluto/rsaref directory so that | |
585 | no external include path has to be defined any longer. | |
586 | ||
587 | - A long-awaited feature has been implemented at last: | |
588 | The local caching of CRLs fetched via HTTP or LDAP, activated | |
589 | by the parameter cachecrls=yes in the config setup section | |
590 | of ipsec.conf. The dynamically fetched CRLs are stored under | |
591 | a unique file name containing the issuer's subjectKeyID | |
592 | in /etc/ipsec.d/crls. | |
593 | ||
594 | - Applied a one-line patch courtesy of Michael Richardson | |
595 | from the Openswan project which fixes the kernel-oops | |
596 | in KLIPS when an snmp daemon is running on the same box. | |
597 | ||
598 | ||
599 | strongswan-2.4.4 | |
600 | ---------------- | |
601 | ||
602 | - Eliminated null length CRL distribution point strings. | |
603 | ||
604 | - Fixed a trust path evaluation bug introduced with 2.4.3 | |
605 | ||
606 | ||
607 | strongswan-2.4.3 | |
608 | ---------------- | |
609 | ||
610 | - Improved the joint OCSP / CRL revocation policy. | |
611 | OCSP responses have precedence over CRL entries. | |
612 | ||
613 | - Introduced support of CRLv2 reason codes. | |
614 | ||
615 | - Fixed a bug with key-pad equipped readers which caused | |
616 | pluto to prompt for the pin via the console when the first | |
617 | occasion to enter the pin via the key-pad was missed. | |
618 | ||
619 | - When pluto is built with LDAP_V3 enabled, the library | |
620 | liblber required by newer versions of openldap is now | |
621 | included. | |
622 | ||
623 | ||
624 | strongswan-2.4.2 | |
625 | ---------------- | |
626 | ||
627 | - Added the _updown_espmark template which requires all | |
628 | incoming ESP traffic to be marked with a default mark | |
629 | value of 50. | |
630 | ||
631 | - Introduced the pkcs11keepstate parameter in the config setup | |
632 | section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11 | |
633 | session and login states are kept as long as possible during | |
634 | the lifetime of pluto. This means that a PIN entry via a key | |
635 | pad has to be done only once. | |
636 | ||
637 | - Introduced the pkcs11module parameter in the config setup | |
638 | section of ipsec.conf which specifies the PKCS#11 module | |
639 | to be used with smart cards. Example: | |
640 | ||
641 | pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo | |
642 | ||
643 | - Added support of smartcard readers equipped with a PIN pad. | |
644 | ||
645 | - Added patch by Jay Pfeifer which detects when netkey | |
646 | modules have been statically built into the Linux 2.6 kernel. | |
647 | ||
648 | - Added two patches by Herbert Xu. The first uses ip xfrm | |
649 | instead of setkey to flush the IPsec policy database. The | |
650 | second sets the optional flag in inbound IPComp SAs only. | |
651 | ||
652 | - Applied Ulrich Weber's patch which fixes an interoperability | |
653 | problem between native IPsec and KLIPS systems caused by | |
654 | setting the replay window to 32 instead of 0 for ipcomp. | |
655 | ||
656 | ||
657 | strongswan-2.4.1 | |
658 | ---------------- | |
659 | ||
660 | - Fixed a bug which caused an unwanted Mode Config request | |
661 | to be initiated in the case where "right" was used to denote | |
662 | the local side in ipsec.conf and "left" the remote side, | |
663 | contrary to the recommendation that "right" be remote and | |
664 | "left" be"local". | |
665 | ||
666 | ||
667 | strongswan-2.4.0a | |
668 | ----------------- | |
669 | ||
670 | - updated Vendor ID to strongSwan-2.4.0 | |
671 | ||
672 | - updated copyright statement to include David Buechi and | |
673 | Michael Meier | |
674 | ||
675 | ||
676 | strongswan-2.4.0 | |
677 | ---------------- | |
678 | ||
679 | - strongSwan now communicates with attached smartcards and | |
680 | USB crypto tokens via the standardized PKCS #11 interface. | |
681 | By default the OpenSC library from www.opensc.org is used | |
682 | but any other PKCS#11 library could be dynamically linked. | |
683 | strongSwan's PKCS#11 API was implemented by David Buechi | |
684 | and Michael Meier, both graduates of the Zurich University | |
685 | of Applied Sciences in Winterthur, Switzerland. | |
686 | ||
687 | - When a %trap eroute is triggered by an outgoing IP packet | |
688 | then the native IPsec stack of the Linux 2.6 kernel [often/ | |
689 | always?] returns an XFRM_ACQUIRE message with an undefined | |
690 | protocol family field and the connection setup fails. | |
691 | As a workaround IPv4 (AF_INET) is now assumed. | |
692 | ||
693 | - the results of the UML test scenarios are now enhanced | |
694 | with block diagrams of the virtual network topology used | |
695 | in a particular test. | |
696 | ||
697 | ||
698 | strongswan-2.3.2 | |
699 | ---------------- | |
700 | ||
701 | - fixed IV used to decrypt informational messages. | |
702 | This bug was introduced with Mode Config functionality. | |
703 | ||
704 | - fixed NCP Vendor ID. | |
705 | ||
706 | - undid one of Ulrich Weber's maximum udp size patches | |
707 | because it caused a segmentation fault with NAT-ed | |
708 | Delete SA messages. | |
709 | ||
710 | - added UML scenarios wildcards and attr-cert which | |
711 | demonstrate the implementation of IPsec policies based | |
712 | on wildcard parameters contained in Distinguished Names and | |
713 | on X.509 attribute certificates, respectively. | |
714 | ||
715 | ||
716 | strongswan-2.3.1 | |
717 | ---------------- | |
718 | ||
719 | - Added basic Mode Config functionality | |
720 | ||
721 | - Added Mathieu Lafon's patch which upgrades the status of | |
722 | the NAT-Traversal implementation to RFC 3947. | |
723 | ||
724 | - The _startklips script now also loads the xfrm4_tunnel | |
725 | module. | |
726 | ||
727 | - Added Ulrich Weber's netlink replay window size and | |
728 | maximum udp size patches. | |
729 | ||
730 | - UML testing now uses the Linux 2.6.10 UML kernel by default. | |
731 | ||
732 | ||
733 | strongswan-2.3.0 | |
734 | ---------------- | |
735 | ||
736 | - Eric Marchionni and Patrik Rayo, both recent graduates from | |
737 | the Zuercher Hochschule Winterthur in Switzerland, created a | |
738 | User-Mode-Linux test setup for strongSwan. For more details | |
739 | please read the INSTALL and README documents in the testing | |
740 | subdirectory. | |
741 | ||
742 | - Full support of group attributes based on X.509 attribute | |
743 | certificates. Attribute certificates can be generated | |
744 | using the openac facility. For more details see | |
745 | ||
746 | man ipsec_openac. | |
747 | ||
748 | The group attributes can be used in connection definitions | |
749 | in order to give IPsec access to specific user groups. | |
750 | This is done with the new parameter left|rightgroups as in | |
751 | ||
752 | rightgroups="Research, Sales" | |
753 | ||
754 | giving access to users possessing the group attributes | |
755 | Research or Sales, only. | |
756 | ||
757 | - In Quick Mode clients with subnet mask /32 are now | |
758 | coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should | |
759 | fix rekeying problems with the SafeNet/SoftRemote and NCP | |
760 | Secure Entry Clients. | |
761 | ||
762 | - Changed the defaults of the ikelifetime and keylife parameters | |
763 | to 3h and 1h, respectively. The maximum allowable values are | |
764 | now both set to 24 h. | |
765 | ||
766 | - Suppressed notification wars between two IPsec peers that | |
767 | could e.g. be triggered by incorrect ISAKMP encryption. | |
768 | ||
769 | - Public RSA keys can now have identical IDs if either the | |
770 | issuing CA or the serial number is different. The serial | |
771 | number of a certificate is now shown by the command | |
772 | ||
773 | ipsec auto --listpubkeys | |
774 | ||
775 | ||
776 | strongswan-2.2.2 | |
777 | ---------------- | |
778 | ||
779 | - Added Tuomo Soini's sourceip feature which allows a strongSwan | |
780 | roadwarrior to use a fixed Virtual IP (see README section 2.6) | |
781 | and reduces the well-known four tunnel case on VPN gateways to | |
782 | a single tunnel definition (see README section 2.4). | |
783 | ||
784 | - Fixed a bug occuring with NAT-Traversal enabled when the responder | |
785 | suddenly turns initiator and the initiator cannot find a matching | |
786 | connection because of the floated IKE port 4500. | |
787 | ||
788 | - Removed misleading ipsec verify command from barf. | |
789 | ||
790 | - Running under the native IP stack, ipsec --version now shows | |
791 | the Linux kernel version (courtesy to the Openswan project). | |
792 | ||
793 | ||
794 | strongswan-2.2.1 | |
795 | ---------------- | |
796 | ||
797 | - Introduced the ipsec auto --listalgs monitoring command which lists | |
798 | all currently registered IKE and ESP algorithms. | |
799 | ||
800 | - Fixed a bug in the ESP algorithm selection occuring when the strict flag | |
801 | is set and the first proposed transform does not match. | |
802 | ||
803 | - Fixed another deadlock in the use of the lock_certs_and_keys() mutex, | |
804 | occuring when a smartcard is present. | |
805 | ||
806 | - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event. | |
807 | ||
808 | - Fixed the printing of the notification names (null) | |
809 | ||
810 | - Applied another of Herbert Xu's Netlink patches. | |
811 | ||
812 | ||
813 | strongswan-2.2.0 | |
814 | ---------------- | |
815 | ||
816 | - Support of Dead Peer Detection. The connection parameter | |
817 | ||
818 | dpdaction=clear|hold | |
819 | ||
820 | activates DPD for the given connection. | |
821 | ||
822 | - The default Opportunistic Encryption (OE) policy groups are not | |
823 | automatically included anymore. Those wishing to activate OE can include | |
824 | the policy group with the following statement in ipsec.conf: | |
825 | ||
826 | include /etc/ipsec.d/examples/oe.conf | |
827 | ||
828 | The default for [right|left]rsasigkey is now set to %cert. | |
829 | ||
830 | - strongSwan now has a Vendor ID of its own which can be activated | |
831 | using the compile option VENDORID | |
832 | ||
833 | - Applied Herbert Xu's patch which sets the compression algorithm correctly. | |
834 | ||
835 | - Applied Herbert Xu's patch fixing an ESPINUDP problem | |
836 | ||
837 | - Applied Herbert Xu's patch setting source/destination port numbers. | |
838 | ||
839 | - Reapplied one of Herbert Xu's NAT-Traversal patches which got | |
840 | lost during the migration from SuperFreeS/WAN. | |
841 | ||
842 | - Fixed a deadlock in the use of the lock_certs_and_keys() mutex. | |
843 | ||
844 | - Fixed the unsharing of alg parameters when instantiating group | |
845 | connection. | |
846 | ||
847 | ||
848 | strongswan-2.1.5 | |
849 | ---------------- | |
850 | ||
851 | - Thomas Walpuski made me aware of a potential DoS attack via | |
852 | a PKCS#7-wrapped certificate bundle which could overwrite valid CA | |
853 | certificates in Pluto's authority certificate store. This vulnerability | |
854 | was fixed by establishing trust in CA candidate certificates up to a | |
855 | trusted root CA prior to insertion into Pluto's chained list. | |
856 | ||
857 | - replaced the --assign option by the -v option in the auto awk script | |
858 | in order to make it run with mawk under debian/woody. | |
859 | ||
860 | ||
861 | strongswan-2.1.4 | |
862 | ---------------- | |
863 | ||
864 | - Split of the status information between ipsec auto --status (concise) | |
865 | and ipsec auto --statusall (verbose). Both commands can be used with | |
866 | an optional connection selector: | |
867 | ||
868 | ipsec auto --status[all] <connection_name> | |
869 | ||
870 | - Added the description of X.509 related features to the ipsec_auto(8) | |
871 | man page. | |
872 | ||
873 | - Hardened the ASN.1 parser in debug mode, especially the printing | |
874 | of malformed distinguished names. | |
875 | ||
876 | - The size of an RSA public key received in a certificate is now restricted to | |
877 | ||
878 | 512 bits <= modulus length <= 8192 bits. | |
879 | ||
880 | - Fixed the debug mode enumeration. | |
881 | ||
882 | ||
883 | strongswan-2.1.3 | |
884 | ---------------- | |
885 | ||
886 | - Fixed another PKCS#7 vulnerability which could lead to an | |
887 | endless loop while following the X.509 trust chain. | |
888 | ||
889 | ||
890 | strongswan-2.1.2 | |
891 | ---------------- | |
892 | ||
893 | - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski | |
894 | that accepted end certificates having identical issuer and subject | |
895 | distinguished names in a multi-tier X.509 trust chain. | |
896 | ||
897 | ||
898 | strongswan-2.1.1 | |
899 | ---------------- | |
900 | ||
901 | - Removed all remaining references to ipsec_netlink.h in KLIPS. | |
902 | ||
903 | ||
904 | strongswan-2.1.0 | |
905 | ---------------- | |
906 | ||
907 | - The new "ca" section allows to define the following parameters: | |
908 | ||
909 | ca kool | |
910 | cacert=koolCA.pem # cacert of kool CA | |
911 | ocspuri=http://ocsp.kool.net:8001 # ocsp server | |
912 | ldapserver=ldap.kool.net # default ldap server | |
913 | crluri=http://www.kool.net/kool.crl # crl distribution point | |
914 | crluri2="ldap:///O=Kool, C= .." # crl distribution point #2 | |
915 | auto=add # add, ignore | |
916 | ||
917 | The ca definitions can be monitored via the command | |
918 | ||
919 | ipsec auto --listcainfos | |
920 | ||
921 | - Fixed cosmetic corruption of /proc filesystem by integrating | |
922 | D. Hugh Redelmeier's freeswan-2.06 kernel fixes. | |
923 | ||
924 | ||
925 | strongswan-2.0.2 | |
926 | ---------------- | |

928 | - Added support for the 818043 NAT-Traversal update of Microsoft's | |
929 | Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode. | |
930 | ||
931 | - A symbolic link to libcrypto is now added in the kernel sources | |
932 | during kernel compilation | |
933 | ||
934 | - Fixed a couple of 64 bit issues (mostly casts to int). | |
935 | Thanks to Ken Bantoft who checked my sources on a 64 bit platform. | |
936 | ||
937 | - Replaced s[n]printf() statements in the kernel by ipsec_snprintf(). | |
938 | Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro | |
939 | of the FreeS/WAN team who solved this problem with the 2.4.25 kernel. | |

942 | strongswan-2.0.1 | |
943 | ---------------- | |
944 | ||
945 | - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName | |
946 | certificate extension which contains no generalName item) can cause | |
947 | a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has | |
948 | been hardened to make it more robust against malformed ASN.1 objects. | |
949 | ||
950 | - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native | |
951 | Linux 2.6 IPsec stack. | |
