1 | strongswan-4.1.2 |
2 | ---------------- | |
3 | ||
e23d98a7 | 4 | - Support for an additional Diffie-Hellman exchange when creating/rekeying |
37fb0355 MW |
5 | a CHILD_SA in IKEv2 (PFS). PFS is enabled when the proposal contains a |
6 | DH group (e.g. "esp=aes128-sha1-modp1536"). Further, DH group negotiation | |
7 | is implemented properly for rekeying. | |
8 | ||
9 | - Support for the AES-XCBC-96 MAC algorithm for IPsec SAs when using IKEv2 | |
10 | (requires linux >= 2.6.20). It is enabled using e.g. "esp=aes256-aesxcbc". | |
11 | ||
d931f465 MW |
12 | - Working IPv4-in-IPv6 and IPv6-in-IPv4 tunnels for linux >= 2.6.21. |
13 | ||
37fb0355 MW |
14 | - Added support for EAP modules which do not establish an MSK. |
15 | ||
8ea7b96f AS |
16 | - The xauth_modules.verify_secret() function now passes the |
17 | connection name. | |
18 | ||
e23d98a7 | 19 | |
ed284399 MW |
20 | strongswan-4.1.1 |
21 | ---------------- | |
22 | ||
23 | - Server side cookie support. If to may IKE_SAs are in CONNECTING state, | |
24 | cookies are enabled and protect against DoS attacks with faked source | |
25 | addresses. Number of IKE_SAs in CONNECTING state is also limited per | |
26 | peer address to avoid resource exhaustion. IKE_SA_INIT messages are | |
27 | compared to properly detect retransmissions and incoming retransmits are | |
28 | detected even if the IKE_SA is blocked (e.g. doing OCSP fetches). | |
29 | ||
db88e37d AS |
30 | - The IKEv2 daemon charon now supports dynamic http- and ldap-based CRL |
31 | fetching enabled by crlcheckinterval > 0 and caching fetched CRLs | |
32 | enabled by cachecrls=yes. | |
33 | ||
3b4f7d92 AS |
34 | - Added the configuration options --enable-nat-transport which enables |
35 | the potentially insecure NAT traversal for IPsec transport mode and | |
36 | --disable-vendor-id which disables the sending of the strongSwan | |
37 | vendor ID. | |
38 | ||
39 | - Fixed a long-standing bug in the pluto IKEv1 daemon which caused | |
40 | a segmentation fault if a malformed payload was detected in the | |
41 | IKE MR2 message and pluto tried to send an encrypted notification | |
42 | message. | |
43 | ||
46b9ff68 AS |
44 | - Added the NATT_IETF_02_N Vendor ID in order to support IKEv1 connections |
45 | with Windows 2003 Server which uses a wrong VID hash. | |
46 | ||
3b4f7d92 | 47 | |
34bbd0c3 | 48 | strongswan-4.1.0 |
cd3958f8 AS |
49 | ---------------- |
50 | ||
51 | - Support of SHA2_384 hash function for protecting IKEv1 | |
52 | negotiations and support of SHA2 signatures in X.509 certificates. | |
53 | ||
54 | - Fixed a serious bug in the computation of the SHA2-512 HMAC | |
55 | function. Introduced automatic self-test of all IKEv1 hash | |
56 | and hmac functions during pluto startup. Failure of a self-test | |
57 | currently issues a warning only but does not exit pluto [yet]. | |
58 | ||
9b45443d MW |
59 | - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2. |
60 | ||
c5d0fbb6 AS |
61 | - Full support of CA information sections. ipsec listcainfos |
62 | now shows all collected crlDistributionPoints and OCSP | |
63 | accessLocations. | |
64 | ||
69ed04bf AS |
65 | - Support of the Online Certificate Status Protocol (OCSP) for IKEv2. |
66 | This feature requires the HTTP fetching capabilities of the libcurl | |
67 | library which must be enabled by setting the --enable-http configure | |
68 | option. | |
69 | ||
9b45443d MW |
70 | - Refactored core of the IKEv2 message processing code, allowing better |
71 | code reuse and separation. | |
72 | ||
73 | - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration | |
74 | payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted | |
75 | by the requestor and installed in a resolv.conf file. | |
76 | ||
77 | - The IKEv2 daemon charon installs a route for each IPsec policy to use | |
78 | the correct source address even if an application does not explicitly | |
79 | specify it. | |
80 | ||
81 | - Integrated the EAP framework into charon which loads pluggable EAP library | |
82 | modules. The ipsec.conf parameter authby=eap initiates EAP authentication | |
83 | on the client side, while the "eap" parameter on the server side defines | |
84 | the EAP method to use for client authentication. | |
85 | A generic client side EAP-Identity module and an EAP-SIM authentication | |
86 | module using a third party card reader implementation are included. | |
87 | ||
88 | - Added client side support for cookies. | |
89 | ||
90 | - Integrated the fixes done at the IKEv2 interoperability bakeoff, including | |
91 | strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor | |
92 | fixes to enhance interoperability with other implementations. | |

1c266d7d AS |
95 | strongswan-4.0.7 |
96 | ---------------- | |
97 | ||
6fdf5f44 AS |
98 | - strongSwan now interoperates with the NCP Secure Entry Client, |
99 | the Shrew Soft VPN Client, and the Cisco VPN client, doing both | |
100 | XAUTH and Mode Config. | |
1c266d7d AS |
101 | |
102 | - UNITY attributes are now recognized and UNITY_BANNER is set | |
103 | to a default string. | |
104 | ||
105 | ||
2b4405a3 MW |
106 | strongswan-4.0.6 |
107 | ---------------- | |
108 | ||
e38a15d4 AS |
109 | - IKEv1: Support for extended authentication (XAUTH) in combination |
110 | with ISAKMP Main Mode RSA or PSK authentication. Both client and | |
111 | server side were implemented. Handling of user credentials can | |
112 | be done by a run-time loadable XAUTH module. By default user | |
113 | credentials are stored in ipsec.secrets. | |
114 | ||
2b4405a3 MW |
115 | - IKEv2: Support for reauthentication when rekeying |
116 | ||
5903179b | 117 | - IKEv2: Support for transport mode |
af87afed | 118 | |
5903179b | 119 | - fixed a lot of bugs related to byte order |
2b4405a3 | 120 | |
5903179b | 121 | - various other bugfixes |
2b4405a3 MW |
122 | |
123 | ||
0cd645d2 AS |
124 | strongswan-4.0.5 |
125 | ---------------- | |
126 | ||
127 | - IKEv1: Implementation of ModeConfig push mode via the new connection | |
128 | keyword modeconfig=push allows interoperability with Cisco VPN gateways. | |
129 | ||
130 | - IKEv1: The command ipsec statusall now shows "DPD active" for all | |
131 | ISAKMP SAs that are under active Dead Peer Detection control. | |
132 | ||
133 | - IKEv2: Charon's logging and debugging framework has been completely rewritten. | |
134 | Instead of logger, special printf() functions are used to directly | |
135 | print objects like hosts (%H) identifications (%D), certificates (%Q), | |
136 | etc. The number of debugging levels have been reduced to: | |
03bf883d | 137 | |
0cd645d2 | 138 | 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private) |
03bf883d | 139 | |
0cd645d2 AS |
140 | The debugging levels can either be specified statically in ipsec.conf as |
141 | ||
142 | config setup | |
03bf883d | 143 | charondebug="lib 1, cfg 3, net 2" |
0cd645d2 | 144 | |
03bf883d | 145 | or changed at runtime via stroke as |
0cd645d2 | 146 | |
03bf883d | 147 | ipsec stroke loglevel cfg 2 |
0cd645d2 AS |
148 | |
149 | ||
48dc3934 MW |
150 | strongswan-4.0.4 |
151 | ---------------- | |
152 | ||
153 | - Implemented full support for IPv6-in-IPv6 tunnels. | |
154 | ||
155 | - Added configuration options for dead peer detection in IKEv2. dpd_action | |
156 | types "clear", "hold" and "restart" are supported. The dpd_timeout | |
157 | value is not used, as the normal retransmission policy applies to | |
158 | detect dead peers. The dpd_delay parameter enables sending of empty | |
159 | informational message to detect dead peers in case of inactivity. | |
160 | ||
161 | - Added support for preshared keys in IKEv2. PSK keys configured in | |
162 | ipsec.secrets are loaded. The authby parameter specifies the authentication | |
163 | method to authentificate ourself, the other peer may use PSK or RSA. | |
164 | ||
165 | - Changed retransmission policy to respect the keyingtries parameter. | |
166 | ||
112ad7c3 AS |
167 | - Added private key decryption. PEM keys encrypted with AES-128/192/256 |
168 | or 3DES are supported. | |
48dc3934 MW |
169 | |
170 | - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to | |
171 | encrypt IKE traffic. | |
172 | ||
173 | - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates | |
174 | signed with such a hash algorithm. | |
175 | ||
176 | - Added initial support for updown scripts. The actions up-host/client and | |
177 | down-host/client are executed. The leftfirewall=yes parameter | |
178 | uses the default updown script to insert dynamic firewall rules, a custom | |
179 | updown script may be specified with the leftupdown parameter. | |
180 | ||
181 | ||
a1310b6b MW |
182 | strongswan-4.0.3 |
183 | ---------------- | |
184 | ||
185 | - Added support for the auto=route ipsec.conf parameter and the | |
186 | ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and | |
187 | CHILD_SAs dynamically on demand when traffic is detected by the | |
188 | kernel. | |
189 | ||
190 | - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter. | |
191 | As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only | |
192 | new keys are generated using perfect forward secrecy. An optional flag | |
193 | which enforces reauthentication will be implemented later. | |
194 | ||
b425d998 AS |
195 | - "sha" and "sha1" are now treated as synonyms in the ike= and esp= |
196 | algorithm configuration statements. | |
197 | ||
198 | ||
bf4df11f AS |
199 | strongswan-4.0.2 |
200 | ---------------- | |
201 | ||
623d3dcf AS |
202 | - Full X.509 certificate trust chain verification has been implemented. |
203 | End entity certificates can be exchanged via CERT payloads. The current | |
204 | default is leftsendcert=always, since CERTREQ payloads are not supported | |
205 | yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls. | |
efa40c11 MW |
206 | |
207 | - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2 | |
208 | would offer more possibilities for traffic selection, but the Linux kernel | |
209 | currently does not support it. That's why we stick with these simple | |
210 | ipsec.conf rules for now. | |
211 | ||
623d3dcf AS |
212 | - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no |
213 | IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear, | |
214 | dpddelay=60s). | |
215 | ||
efa40c11 MW |
216 | - Initial NAT traversal support in IKEv2. Charon includes NAT detection |
217 | notify payloads to detect NAT routers between the peers. It switches | |
218 | to port 4500, uses UDP encapsulated ESP packets, handles peer address | |
219 | changes gracefully and sends keep alive message periodically. | |
220 | ||
221 | - Reimplemented IKE_SA state machine for charon, which allows simultaneous | |
222 | rekeying, more shared code, cleaner design, proper retransmission | |
223 | and a more extensible code base. | |
224 | ||
cfd8b27f AS |
225 | - The mixed PSK/RSA roadwarrior detection capability introduced by the |
226 | strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal | |
227 | payloads by the responder right before any defined IKE Main Mode state had | |
228 | been established. Although any form of bad proposal syntax was being correctly | |
229 | detected by the payload parser, the subsequent error handler didn't check | |
230 | the state pointer before logging current state information, causing an | |
231 | immediate crash of the pluto keying daemon due to a NULL pointer. | |
232 | ||
bf4df11f | 233 | |
7e81e975 MW |
234 | strongswan-4.0.1 |
235 | ---------------- | |
236 | ||
c15c3d4b MW |
237 | - Added algorithm selection to charon: New default algorithms for |
238 | ike=aes128-sha-modp2048, as both daemons support it. The default | |
239 | for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles | |
240 | the ike/esp parameter the same way as pluto. As this syntax does | |
241 | not allow specification of a pseudo random function, the same | |
242 | algorithm as for integrity is used (currently sha/md5). Supported | |
243 | algorithms for IKE: | |
244 | Encryption: aes128, aes192, aes256 | |
245 | Integrity/PRF: md5, sha (using hmac) | |
246 | DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192 | |
247 | and for ESP: | |
248 | Encryption: aes128, aes192, aes256, 3des, blowfish128, | |
249 | blowfish192, blowfish256 | |
250 | Integrity: md5, sha1 | |
251 | More IKE encryption algorithms will come after porting libcrypto into | |
252 | libstrongswan. | |
f2c2d395 | 253 | |
c15c3d4b MW |
254 | - initial support for rekeying CHILD_SAs using IKEv2. Currently no |
255 | perfect forward secrecy is used. The rekeying parameters rekey, | |
22ff6f57 | 256 | rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported |
c15c3d4b MW |
257 | when using IKEv2. WARNING: charon currently is unable to handle |
258 | simultaneous rekeying. To avoid such a situation, use a large | |
259 | rekeyfuzz, or even better, set rekey=no on one peer. | |
22ff6f57 | 260 | |
7e81e975 MW |
261 | - support for host2host, net2net, host2net (roadwarrior) tunnels |
262 | using predefined RSA certificates (see uml scenarios for | |
263 | configuration examples). | |
264 | ||
f2c2d395 MW |
265 | - new build environment featuring autotools. Features such |
266 | as HTTP, LDAP and smartcard support may be enabled using | |
267 | the ./configure script. Changing install directories | |
268 | is possible, too. See ./configure --help for more details. | |
269 | ||
22ff6f57 MW |
270 | - better integration of charon with ipsec starter, which allows |
271 | (almost) transparent operation with both daemons. charon | |
272 | handles ipsec commands up, down, status, statusall, listall, | |
273 | listcerts and allows proper load, reload and delete of connections | |
274 | via ipsec starter. | |
275 | ||
b425d998 | 276 | |
9820c0e2 MW |
277 | strongswan-4.0.0 |
278 | ---------------- | |
279 | ||
280 | - initial support of the IKEv2 protocol. Connections in | |
281 | ipsec.conf designated by keyexchange=ikev2 are negotiated | |
282 | by the new IKEv2 charon keying daemon whereas those marked | |
283 | by keyexchange=ikev1 or the default keyexchange=ike are | |
284 | handled thy the IKEv1 pluto keying daemon. Currently only | |
285 | a limited subset of functions are available with IKEv2 | |
286 | (Default AES encryption, authentication based on locally | |
287 | imported X.509 certificates, unencrypted private RSA keys | |
288 | in PKCS#1 file format, limited functionality of the ipsec | |
289 | status command). | |
290 | ||
291 | ||
997358a6 MW |
292 | strongswan-2.7.0 |
293 | ---------------- | |
294 | ||
295 | - the dynamic iptables rules from the _updown_x509 template | |
296 | for KLIPS and the _updown_policy template for NETKEY have | |
297 | been merged into the default _updown script. The existing | |
298 | left|rightfirewall keyword causes the automatic insertion | |
299 | and deletion of ACCEPT rules for tunneled traffic upon | |
300 | the successful setup and teardown of an IPsec SA, respectively. | |
301 | left|rightfirwall can be used with KLIPS under any Linux 2.4 | |
302 | kernel or with NETKEY under a Linux kernel version >= 2.6.16 | |
303 | in conjuction with iptables >= 1.3.5. For NETKEY under a Linux | |
304 | kernel version < 2.6.16 which does not support IPsec policy | |
305 | matching yet, please continue to use a copy of the _updown_espmark | |
306 | template loaded via the left|rightupdown keyword. | |
307 | ||
308 | - a new left|righthostaccess keyword has been introduced which | |
309 | can be used in conjunction with left|rightfirewall and the | |
310 | default _updown script. By default leftfirewall=yes inserts | |
311 | a bi-directional iptables FORWARD rule for a local client network | |
312 | with a netmask different from 255.255.255.255 (single host). | |
313 | This does not allow to access the VPN gateway host via its | |
314 | internal network interface which is part of the client subnet | |
315 | because an iptables INPUT and OUTPUT rule would be required. | |
316 | lefthostaccess=yes will cause this additional ACCEPT rules to | |
317 | be inserted. | |
318 | ||
319 | - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal | |
320 | payload is preparsed in order to find out whether the roadwarrior | |
321 | requests PSK or RSA so that a matching connection candidate can | |
322 | be found. | |
323 | ||
324 | ||
325 | strongswan-2.6.4 | |
326 | ---------------- | |
327 | ||
328 | - the new _updown_policy template allows ipsec policy based | |
329 | iptables firewall rules. Required are iptables version | |
330 | >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes | |
331 | the _updown_espmark template, so that no INPUT mangle rules | |
332 | are required any more. | |
333 | ||
334 | - added support of DPD restart mode | |
335 | ||
336 | - ipsec starter now allows the use of wildcards in include | |
337 | statements as e.g. in "include /etc/my_ipsec/*.conf". | |
338 | Patch courtesy of Matthias Haas. | |
339 | ||
340 | - the Netscape OID 'employeeNumber' is now recognized and can be | |
341 | used as a Relative Distinguished Name in certificates. | |
342 | ||
343 | ||
344 | strongswan-2.6.3 | |
345 | ---------------- | |
346 | ||
347 | - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec | |
348 | command and not of ipsec setup any more. | |
349 | ||
350 | - ipsec starter now supports AH authentication in conjunction with | |
351 | ESP encryption. AH authentication is configured in ipsec.conf | |
352 | via the auth=ah parameter. | |
353 | ||
354 | - The command ipsec scencrypt|scdecrypt <args> is now an alias for | |
355 | ipsec whack --scencrypt|scdecrypt <args>. | |
356 | ||
357 | - get_sa_info() now determines for the native netkey IPsec stack | |
358 | the exact time of the last use of an active eroute. This information | |
359 | is used by the Dead Peer Detection algorithm and is also displayed by | |
360 | the ipsec status command. | |
361 | ||
362 | ||
363 | strongswan-2.6.2 | |
364 | ---------------- | |
365 | ||
366 | - running under the native Linux 2.6 IPsec stack, the function | |
367 | get_sa_info() is called by ipsec auto --status to display the current | |
368 | number of transmitted bytes per IPsec SA. | |
369 | ||
370 | - get_sa_info() is also used by the Dead Peer Detection process to detect | |
371 | recent ESP activity. If ESP traffic was received from the peer within | |
372 | the last dpd_delay interval then no R_Y_THERE notification must be sent. | |
373 | ||
374 | - strongSwan now supports the Relative Distinguished Name "unstructuredName" | |
375 | in ID_DER_ASN1_DN identities. The following notations are possible: | |
376 | ||
377 | rightid="unstructuredName=John Doe" | |
378 | rightid="UN=John Doe" | |
379 | ||
380 | - fixed a long-standing bug which caused PSK-based roadwarrior connections | |
381 | to segfault in the function id.c:same_id() called by keys.c:get_secret() | |
382 | if an FQDN, USER_FQDN, or Key ID was defined, as in the following example. | |
383 | ||
384 | conn rw | |
385 | right=%any | |
386 | rightid=@foo.bar | |
387 | authby=secret | |
388 | ||
389 | - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall). | |
390 | ||
391 | - ipsec starter didn't set host_addr and client.addr ports in whack msg. | |
392 | ||
393 | - in order to guarantee backwards-compatibility with the script-based | |
394 | auto function (e.g. auto --replace), the ipsec starter scripts stores | |
395 | the defaultroute information in the temporary file /var/run/ipsec.info. | |
396 | ||
397 | - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH | |
398 | Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config | |
399 | servers. | |
400 | ||
401 | - the ipsec starter now also recognizes the parameters authby=never and | |
402 | type=passthrough|pass|drop|reject. | |
403 | ||
404 | ||
405 | strongswan-2.6.1 | |
406 | ---------------- | |
407 | ||
408 | - ipsec starter now supports the also parameter which allows | |
409 | a modular structure of the connection definitions. Thus | |
410 | "ipsec start" is now ready to replace "ipsec setup". | |
411 | ||
412 | ||
413 | strongswan-2.6.0 | |
414 | ---------------- | |
415 | ||
416 | - Mathieu Lafon's popular ipsec starter tool has been added to the | |
417 | strongSwan distribution. Many thanks go to Stephan Scholz from astaro | |
418 | for his integration work. ipsec starter is a C program which is going | |
419 | to replace the various shell and awk starter scripts (setup, _plutoload, | |
420 | _plutostart, _realsetup, _startklips, _confread, and auto). Since | |
421 | ipsec.conf is now parsed only once, the starting of multiple tunnels is | |
422 | accelerated tremedously. | |
423 | ||
424 | - Added support of %defaultroute to the ipsec starter. If the IP address | |
425 | changes, a HUP signal to the ipsec starter will automatically | |
426 | reload pluto's connections. | |
427 | ||
428 | - moved most compile time configurations from pluto/Makefile to | |
429 | Makefile.inc by defining the options USE_LIBCURL, USE_LDAP, | |
430 | USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE. | |
431 | ||
432 | - removed the ipsec verify and ipsec newhostkey commands | |
433 | ||
434 | - fixed some 64-bit issues in formatted print statements | |
435 | ||
436 | - The scepclient functionality implementing the Simple Certificate | |
437 | Enrollment Protocol (SCEP) is nearly complete but hasn't been | |
438 | documented yet. | |
439 | ||
440 | ||
441 | strongswan-2.5.7 | |
442 | ---------------- | |
443 | ||
444 | - CA certicates are now automatically loaded from a smartcard | |
445 | or USB crypto token and appear in the ipsec auto --listcacerts | |
446 | listing. | |
447 | ||
448 | ||
449 | strongswan-2.5.6 | |
450 | ---------------- | |
451 | ||
452 | - when using "ipsec whack --scencrypt <data>" with a PKCS#11 | |
453 | library that does not support the C_Encrypt() Cryptoki | |
454 | function (e.g. OpenSC), the RSA encryption is done in | |
455 | software using the public key fetched from the smartcard. | |
456 | ||
457 | - The scepclient function now allows to define the | |
458 | validity of a self-signed certificate using the --days, | |
459 | --startdate, and --enddate options. The default validity | |
460 | has been changed from one year to five years. | |
461 | ||
462 | ||
463 | strongswan-2.5.5 | |
464 | ---------------- | |
465 | ||
466 | - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11 | |
467 | interface to other applications for RSA encryption and decryption | |
468 | via the whack interface. Notation: | |
469 | ||
470 | ipsec whack --scencrypt <data> | |
471 | [--inbase 16|hex|64|base64|256|text|ascii] | |
472 | [--outbase 16|hex|64|base64|256|text|ascii] | |
473 | [--keyid <keyid>] | |
474 | ||
475 | ipsec whack --scdecrypt <data> | |
476 | [--inbase 16|hex|64|base64|256|text|ascii] | |
477 | [--outbase 16|hex|64|base64|256|text|ascii] | |
478 | [--keyid <keyid>] | |
479 | ||
480 | The default setting for inbase and outbase is hex. | |
481 | ||
482 | The new proxy interface can be used for securing symmetric | |
483 | encryption keys required by the cryptoloop or dm-crypt | |
484 | disk encryption schemes, especially in the case when | |
485 | pkcs11keepstate=yes causes pluto to lock the pkcs11 slot | |
486 | permanently. | |
487 | ||
488 | - if the file /etc/ipsec.secrets is lacking during the startup of | |
489 | pluto then the root-readable file /etc/ipsec.d/private/myKey.der | |
490 | containing a 2048 bit RSA private key and a matching self-signed | |
491 | certificate stored in the file /etc/ipsec.d/certs/selfCert.der | |
492 | is automatically generated by calling the function | |
493 | ||
494 | ipsec scepclient --out pkcs1 --out cert-self | |
495 | ||
496 | scepclient was written by Jan Hutter and Martin Willi, students | |
497 | at the University of Applied Sciences in Rapperswil, Switzerland. | |
498 | ||
499 | ||
500 | strongswan-2.5.4 | |
501 | ---------------- | |
502 | ||
503 | - the current extension of the PKCS#7 framework introduced | |
504 | a parsing error in PKCS#7 wrapped X.509 certificates that are | |
505 | e.g. transmitted by Windows XP when multi-level CAs are used. | |
506 | the parsing syntax has been fixed. | |
507 | ||
508 | - added a patch by Gerald Richter which tolerates multiple occurrences | |
509 | of the ipsec0 interface when using KLIPS. | |
510 | ||
511 | ||
512 | strongswan-2.5.3 | |
513 | ---------------- | |
514 | ||
515 | - with gawk-3.1.4 the word "default2 has become a protected | |
516 | keyword for use in switch statements and cannot be used any | |
517 | more in the strongSwan scripts. This problem has been | |
518 | solved by renaming "default" to "defaults" and "setdefault" | |
519 | in the scripts _confread and auto, respectively. | |
520 | ||
521 | - introduced the parameter leftsendcert with the values | |
522 | ||
523 | always|yes (the default, always send a cert) | |
524 | ifasked (send the cert only upon a cert request) | |
525 | never|no (never send a cert, used for raw RSA keys and | |
526 | self-signed certs) | |
527 | ||
528 | - fixed the initialization of the ESP key length to a default of | |
529 | 128 bits in the case that the peer does not send a key length | |
530 | attribute for AES encryption. | |
531 | ||
532 | - applied Herbert Xu's uniqueIDs patch | |
533 | ||
534 | - applied Herbert Xu's CLOEXEC patches | |
535 | ||
536 | ||
537 | strongswan-2.5.2 | |
538 | ---------------- | |
539 | ||
540 | - CRLs can now be cached also in the case when the issuer's | |
541 | certificate does not contain a subjectKeyIdentifier field. | |
542 | In that case the subjectKeyIdentifier is computed by pluto as the | |
543 | 160 bit SHA-1 hash of the issuer's public key in compliance | |
544 | with section 4.2.1.2 of RFC 3280. | |
545 | ||
546 | - Fixed a bug introduced by strongswan-2.5.1 which eliminated | |
547 | not only multiple Quick Modes of a given connection but also | |
548 | multiple connections between two security gateways. | |
549 | ||
550 | ||
551 | strongswan-2.5.1 | |
552 | ---------------- | |
553 | ||
554 | - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute | |
555 | installed either by setting auto=route in ipsec.conf or by | |
556 | a connection put into hold, generates an XFRM_AQUIRE event | |
557 | for each packet that wants to use the not-yet exisiting | |
558 | tunnel. Up to now each XFRM_AQUIRE event led to an entry in | |
559 | the Quick Mode queue, causing multiple IPsec SA to be | |
560 | established in rapid succession. Starting with strongswan-2.5.1 | |
561 | only a single IPsec SA is established per host-pair connection. | |
562 | ||
563 | - Right after loading the PKCS#11 module, all smartcard slots are | |
564 | searched for certificates. The result can be viewed using | |
565 | the command | |
566 | ||
567 | ipsec auto --listcards | |
568 | ||
569 | The certificate objects found in the slots are numbered | |
570 | starting with #1, #2, etc. This position number can be used to address | |
571 | certificates (leftcert=%smartcard) and keys (: PIN %smartcard) | |
572 | in ipsec.conf and ipsec.secrets, respectively: | |
573 | ||
574 | %smartcard (selects object #1) | |
575 | %smartcard#1 (selects object #1) | |
576 | %smartcard#3 (selects object #3) | |
577 | ||
578 | As an alternative the existing retrieval scheme can be used: | |
579 | ||
580 | %smartcard:45 (selects object with id=45) | |
581 | %smartcard0 (selects first object in slot 0) | |
582 | %smartcard4:45 (selects object in slot 4 with id=45) | |
583 | ||
584 | - Depending on the settings of CKA_SIGN and CKA_DECRYPT | |
585 | private key flags either C_Sign() or C_Decrypt() is used | |
586 | to generate a signature. | |
587 | ||
588 | - The output buffer length parameter siglen in C_Sign() | |
589 | is now initialized to the actual size of the output | |
590 | buffer prior to the function call. This fixes the | |
591 | CKR_BUFFER_TOO_SMALL error that could occur when using | |
592 | the OpenSC PKCS#11 module. | |
593 | ||
594 | - Changed the initialization of the PKCS#11 CK_MECHANISM in | |
595 | C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }. | |
596 | ||
597 | - Refactored the RSA public/private key code and transferred it | |
598 | from keys.c to the new pkcs1.c file as a preparatory step | |
599 | towards the release of the SCEP client. | |
600 | ||
601 | ||
602 | strongswan-2.5.0 | |
603 | ---------------- | |
604 | ||
605 | - The loading of a PKCS#11 smartcard library module during | |
606 | runtime does not require OpenSC library functions any more | |
607 | because the corresponding code has been integrated into | |
608 | smartcard.c. Also the RSAREF pkcs11 header files have been | |
609 | included in a newly created pluto/rsaref directory so that | |
610 | no external include path has to be defined any longer. | |
611 | ||
612 | - A long-awaited feature has been implemented at last: | |
613 | The local caching of CRLs fetched via HTTP or LDAP, activated | |
614 | by the parameter cachecrls=yes in the config setup section | |
615 | of ipsec.conf. The dynamically fetched CRLs are stored under | |
616 | a unique file name containing the issuer's subjectKeyID | |
617 | in /etc/ipsec.d/crls. | |
618 | ||
619 | - Applied a one-line patch courtesy of Michael Richardson | |
620 | from the Openswan project which fixes the kernel-oops | |
621 | in KLIPS when an snmp daemon is running on the same box. | |
622 | ||
623 | ||
624 | strongswan-2.4.4 | |
625 | ---------------- | |
626 | ||
627 | - Eliminated null length CRL distribution point strings. | |
628 | ||
629 | - Fixed a trust path evaluation bug introduced with 2.4.3 | |
630 | ||
631 | ||
632 | strongswan-2.4.3 | |
633 | ---------------- | |
634 | ||
635 | - Improved the joint OCSP / CRL revocation policy. | |
636 | OCSP responses have precedence over CRL entries. | |
637 | ||
638 | - Introduced support of CRLv2 reason codes. | |
639 | ||
640 | - Fixed a bug with key-pad equipped readers which caused | |
641 | pluto to prompt for the pin via the console when the first | |
642 | occasion to enter the pin via the key-pad was missed. | |
643 | ||
644 | - When pluto is built with LDAP_V3 enabled, the library | |
645 | liblber required by newer versions of openldap is now | |
646 | included. | |
647 | ||
648 | ||
649 | strongswan-2.4.2 | |
650 | ---------------- | |
651 | ||
652 | - Added the _updown_espmark template which requires all | |
653 | incoming ESP traffic to be marked with a default mark | |
654 | value of 50. | |
655 | ||
656 | - Introduced the pkcs11keepstate parameter in the config setup | |
657 | section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11 | |
658 | session and login states are kept as long as possible during | |
659 | the lifetime of pluto. This means that a PIN entry via a key | |
660 | pad has to be done only once. | |
661 | ||
662 | - Introduced the pkcs11module parameter in the config setup | |
663 | section of ipsec.conf which specifies the PKCS#11 module | |
664 | to be used with smart cards. Example: | |
665 | ||
666 | pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo | |
667 | ||
668 | - Added support of smartcard readers equipped with a PIN pad. | |
669 | ||
670 | - Added patch by Jay Pfeifer which detects when netkey | |
671 | modules have been statically built into the Linux 2.6 kernel. | |
672 | ||
673 | - Added two patches by Herbert Xu. The first uses ip xfrm | |
674 | instead of setkey to flush the IPsec policy database. The | |
675 | second sets the optional flag in inbound IPComp SAs only. | |
676 | ||
677 | - Applied Ulrich Weber's patch which fixes an interoperability | |
678 | problem between native IPsec and KLIPS systems caused by | |
679 | setting the replay window to 32 instead of 0 for ipcomp. | |
680 | ||
681 | ||
682 | strongswan-2.4.1 | |
683 | ---------------- | |
684 | ||
685 | - Fixed a bug which caused an unwanted Mode Config request | |
686 | to be initiated in the case where "right" was used to denote | |
687 | the local side in ipsec.conf and "left" the remote side, | |
688 | contrary to the recommendation that "right" be remote and | |
689 | "left" be"local". | |
690 | ||
691 | ||
692 | strongswan-2.4.0a | |
693 | ----------------- | |
694 | ||
695 | - updated Vendor ID to strongSwan-2.4.0 | |
696 | ||
697 | - updated copyright statement to include David Buechi and | |
698 | Michael Meier | |
699 | ||
700 | ||
701 | strongswan-2.4.0 | |
702 | ---------------- | |
703 | ||
704 | - strongSwan now communicates with attached smartcards and | |
705 | USB crypto tokens via the standardized PKCS #11 interface. | |
706 | By default the OpenSC library from www.opensc.org is used | |
707 | but any other PKCS#11 library could be dynamically linked. | |
708 | strongSwan's PKCS#11 API was implemented by David Buechi | |
709 | and Michael Meier, both graduates of the Zurich University | |
710 | of Applied Sciences in Winterthur, Switzerland. | |
711 | ||
712 | - When a %trap eroute is triggered by an outgoing IP packet | |
713 | then the native IPsec stack of the Linux 2.6 kernel [often/ | |
714 | always?] returns an XFRM_ACQUIRE message with an undefined | |
715 | protocol family field and the connection setup fails. | |
716 | As a workaround IPv4 (AF_INET) is now assumed. | |
717 | ||
718 | - the results of the UML test scenarios are now enhanced | |
719 | with block diagrams of the virtual network topology used | |
720 | in a particular test. | |
721 | ||
722 | ||
723 | strongswan-2.3.2 | |
724 | ---------------- | |
725 | ||
726 | - fixed IV used to decrypt informational messages. | |
727 | This bug was introduced with Mode Config functionality. | |
728 | ||
729 | - fixed NCP Vendor ID. | |
730 | ||
731 | - undid one of Ulrich Weber's maximum udp size patches | |
732 | because it caused a segmentation fault with NAT-ed | |
733 | Delete SA messages. | |
734 | ||
735 | - added UML scenarios wildcards and attr-cert which | |
736 | demonstrate the implementation of IPsec policies based | |
737 | on wildcard parameters contained in Distinguished Names and | |
738 | on X.509 attribute certificates, respectively. | |
739 | ||
740 | ||
741 | strongswan-2.3.1 | |
742 | ---------------- | |
743 | ||
744 | - Added basic Mode Config functionality | |
745 | ||
746 | - Added Mathieu Lafon's patch which upgrades the status of | |
747 | the NAT-Traversal implementation to RFC 3947. | |
748 | ||
749 | - The _startklips script now also loads the xfrm4_tunnel | |
750 | module. | |
751 | ||
752 | - Added Ulrich Weber's netlink replay window size and | |
753 | maximum udp size patches. | |
754 | ||
755 | - UML testing now uses the Linux 2.6.10 UML kernel by default. | |
756 | ||
757 | ||
758 | strongswan-2.3.0 | |
759 | ---------------- | |
760 | ||
761 | - Eric Marchionni and Patrik Rayo, both recent graduates from | |
762 | the Zuercher Hochschule Winterthur in Switzerland, created a | |
763 | User-Mode-Linux test setup for strongSwan. For more details | |
764 | please read the INSTALL and README documents in the testing | |
765 | subdirectory. | |
766 | ||
767 | - Full support of group attributes based on X.509 attribute | |
768 | certificates. Attribute certificates can be generated | |
769 | using the openac facility. For more details see | |
770 | ||
771 | man ipsec_openac. | |
772 | ||
773 | The group attributes can be used in connection definitions | |
774 | in order to give IPsec access to specific user groups. | |
775 | This is done with the new parameter left|rightgroups as in | |
776 | ||
777 | rightgroups="Research, Sales" | |
778 | ||
779 | giving access to users possessing the group attributes | |
780 | Research or Sales, only. | |
781 | ||
782 | - In Quick Mode clients with subnet mask /32 are now | |
783 | coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should | |
784 | fix rekeying problems with the SafeNet/SoftRemote and NCP | |
785 | Secure Entry Clients. | |
786 | ||
787 | - Changed the defaults of the ikelifetime and keylife parameters | |
788 | to 3h and 1h, respectively. The maximum allowable values are | |
789 | now both set to 24 h. | |
790 | ||
791 | - Suppressed notification wars between two IPsec peers that | |
792 | could e.g. be triggered by incorrect ISAKMP encryption. | |
793 | ||
794 | - Public RSA keys can now have identical IDs if either the | |
795 | issuing CA or the serial number is different. The serial | |
796 | number of a certificate is now shown by the command | |
797 | ||
798 | ipsec auto --listpubkeys | |
799 | ||
800 | ||
801 | strongswan-2.2.2 | |
802 | ---------------- | |
803 | ||
804 | - Added Tuomo Soini's sourceip feature which allows a strongSwan | |
805 | roadwarrior to use a fixed Virtual IP (see README section 2.6) | |
806 | and reduces the well-known four tunnel case on VPN gateways to | |
807 | a single tunnel definition (see README section 2.4). | |
808 | ||
809 | - Fixed a bug occuring with NAT-Traversal enabled when the responder | |
810 | suddenly turns initiator and the initiator cannot find a matching | |
811 | connection because of the floated IKE port 4500. | |
812 | ||
813 | - Removed misleading ipsec verify command from barf. | |
814 | ||
815 | - Running under the native IP stack, ipsec --version now shows | |
816 | the Linux kernel version (courtesy to the Openswan project). | |
817 | ||
818 | ||
819 | strongswan-2.2.1 | |
820 | ---------------- | |
821 | ||
822 | - Introduced the ipsec auto --listalgs monitoring command which lists | |
823 | all currently registered IKE and ESP algorithms. | |
824 | ||
825 | - Fixed a bug in the ESP algorithm selection occuring when the strict flag | |
826 | is set and the first proposed transform does not match. | |
827 | ||
828 | - Fixed another deadlock in the use of the lock_certs_and_keys() mutex, | |
829 | occuring when a smartcard is present. | |
830 | ||
831 | - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event. | |
832 | ||
833 | - Fixed the printing of the notification names (null) | |
834 | ||
835 | - Applied another of Herbert Xu's Netlink patches. | |
836 | ||
837 | ||
838 | strongswan-2.2.0 | |
839 | ---------------- | |
840 | ||
841 | - Support of Dead Peer Detection. The connection parameter | |
842 | ||
843 | dpdaction=clear|hold | |
844 | ||
845 | activates DPD for the given connection. | |
846 | ||
847 | - The default Opportunistic Encryption (OE) policy groups are not | |
848 | automatically included anymore. Those wishing to activate OE can include | |
849 | the policy group with the following statement in ipsec.conf: | |
850 | ||
851 | include /etc/ipsec.d/examples/oe.conf | |
852 | ||
853 | The default for [right|left]rsasigkey is now set to %cert. | |
854 | ||
855 | - strongSwan now has a Vendor ID of its own which can be activated | |
856 | using the compile option VENDORID | |
857 | ||
858 | - Applied Herbert Xu's patch which sets the compression algorithm correctly. | |
859 | ||
860 | - Applied Herbert Xu's patch fixing an ESPINUDP problem | |
861 | ||
862 | - Applied Herbert Xu's patch setting source/destination port numbers. | |
863 | ||
864 | - Reapplied one of Herbert Xu's NAT-Traversal patches which got | |
865 | lost during the migration from SuperFreeS/WAN. | |
866 | ||
867 | - Fixed a deadlock in the use of the lock_certs_and_keys() mutex. | |
868 | ||
869 | - Fixed the unsharing of alg parameters when instantiating group | |
870 | connection. | |
871 | ||
872 | ||
873 | strongswan-2.1.5 | |
874 | ---------------- | |
875 | ||
876 | - Thomas Walpuski made me aware of a potential DoS attack via | |
877 | a PKCS#7-wrapped certificate bundle which could overwrite valid CA | |
878 | certificates in Pluto's authority certificate store. This vulnerability | |
879 | was fixed by establishing trust in CA candidate certificates up to a | |
880 | trusted root CA prior to insertion into Pluto's chained list. | |
881 | ||
882 | - replaced the --assign option by the -v option in the auto awk script | |
883 | in order to make it run with mawk under debian/woody. | |
884 | ||
885 | ||
886 | strongswan-2.1.4 | |
887 | ---------------- | |
888 | ||
889 | - Split of the status information between ipsec auto --status (concise) | |
890 | and ipsec auto --statusall (verbose). Both commands can be used with | |
891 | an optional connection selector: | |
892 | ||
893 | ipsec auto --status[all] <connection_name> | |
894 | ||
895 | - Added the description of X.509 related features to the ipsec_auto(8) | |
896 | man page. | |
897 | ||
898 | - Hardened the ASN.1 parser in debug mode, especially the printing | |
899 | of malformed distinguished names. | |
900 | ||
901 | - The size of an RSA public key received in a certificate is now restricted to | |
902 | ||
903 | 512 bits <= modulus length <= 8192 bits. | |
904 | ||
905 | - Fixed the debug mode enumeration. | |
906 | ||
907 | ||
908 | strongswan-2.1.3 | |
909 | ---------------- | |
910 | ||
911 | - Fixed another PKCS#7 vulnerability which could lead to an | |
912 | endless loop while following the X.509 trust chain. | |
913 | ||
914 | ||
915 | strongswan-2.1.2 | |
916 | ---------------- | |
917 | ||
918 | - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski | |
919 | that accepted end certificates having identical issuer and subject | |
920 | distinguished names in a multi-tier X.509 trust chain. | |
921 | ||
922 | ||
923 | strongswan-2.1.1 | |
924 | ---------------- | |
925 | ||
926 | - Removed all remaining references to ipsec_netlink.h in KLIPS. | |
927 | ||
928 | ||
929 | strongswan-2.1.0 | |
930 | ---------------- | |
931 | ||
932 | - The new "ca" section allows to define the following parameters: | |
933 | ||
934 | ca kool | |
935 | cacert=koolCA.pem # cacert of kool CA | |
936 | ocspuri=http://ocsp.kool.net:8001 # ocsp server | |
937 | ldapserver=ldap.kool.net # default ldap server | |
938 | crluri=http://www.kool.net/kool.crl # crl distribution point | |
939 | crluri2="ldap:///O=Kool, C= .." # crl distribution point #2 | |
940 | auto=add # add, ignore | |
941 | ||
942 | The ca definitions can be monitored via the command | |
943 | ||
944 | ipsec auto --listcainfos | |
945 | ||
946 | - Fixed cosmetic corruption of /proc filesystem by integrating | |
947 | D. Hugh Redelmeier's freeswan-2.06 kernel fixes. | |
948 | ||
949 | ||
950 | strongswan-2.0.2 | |
951 | ---------------- | |
952 | ||
953 | - Added support for the 818043 NAT-Traversal update of Microsoft's | |
954 | Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode. | |
955 | ||
956 | - A symbolic link to libcrypto is now added in the kernel sources | |
957 | during kernel compilation | |
958 | ||
959 | - Fixed a couple of 64 bit issues (mostly casts to int). | |
960 | Thanks to Ken Bantoft who checked my sources on a 64 bit platform. | |
961 | ||
962 | - Replaced s[n]printf() statements in the kernel by ipsec_snprintf(). | |
963 | Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro | |
964 | of the FreeS/WAN team who solved this problem with the 2.4.25 kernel. | |
965 | ||
966 | ||
967 | strongswan-2.0.1 | |
968 | ---------------- | |
969 | ||
970 | - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName | |
971 | certificate extension which contains no generalName item) can cause | |
972 | a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has | |
973 | been hardened to make it more robust against malformed ASN.1 objects. | |
974 | ||
975 | - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native | |
976 | Linux 2.6 IPsec stack. | |
977 | ||
978 | ||
979 | strongswan-2.0.0 | |
980 | ---------------- | |
981 | ||
982 | - based on freeswan-2.04, x509-1.5.3, nat-0.6c, alg-0.8.1rc12 |
