1 | strongswan-4.2.1 |
2 | ---------------- | |
3 | ||
58caabf7 | 4 | - hash and url |
5c5d67d6 | 5 | |
58caabf7 MW |
6 | - The IKEv2 daemon charon now supports the "uniqueids" option to close multiple |
7 | IKE_SAs with the same peer. The option value "keep" prefers existing | |
8 | connection setups over new ones, where the value "replace" replaces existing | |
9 | connections. | |
10 | ||
11 | - The crypto factory in libstrongswan additionaly supports random number | |
12 | generators, plugins may provide other sources of randomness. The default | |
13 | plugin reads random data from /dev/(u)random. | |
14 | ||
15 | - Extended the credential framework by a caching option to allow plugins | |
16 | persistent caching of fetched credentials. The "cachecrl" option has been | |
17 | reeimplemented. | |
18 | ||
19 | - The new trustchain verification introduced in 4.2.0 has been parallelized. | |
20 | Threads fetching CRL or OCSP information no longer block other threads. | |
5c5d67d6 | 21 | |
58caabf7 MW |
22 | - A new IKEv2 configuration attribute framework has been introduced allowing |
23 | plugins to provide virtual IP addresses, and in the future, other | |
24 | configuration attribute services (e.g. DNS/WINS servers). | |
5c5d67d6 | 25 | |
58caabf7 MW |
26 | - The stroke plugin has been extended to provide virutal IP addresses from |
27 | a pool defined in ipsec.conf. The "rightsourceip" parameter now accepts | |
28 | address pools in CIDR notation (e.g. 10.1.1.0/24). The parameter also accepts | |
29 | the value "%poolname", where "poolname" identifies a pool provided by a | |
30 | seperate plugin. | |
31 | ||
32 | - Fixed compilation on uClibc and a couple of minor bugs. | |
33 | ||
34 | - set DPD defaults to dpd_delay=30s and dpd_timeout=150s. | |

37 | ---------------- | |
38 | ||
16f5dacd MW |
39 | - libstrongswan has been modularized to attach crypto algorithms, |
40 | credential implementations (keys, certificates) and fetchers dynamically | |
41 | through plugins. Existing code has been ported to plugins: | |
42 | - RSA/Diffie-Hellman implementation using the GNU Multi Precision library | |
43 | - X509 certificate system supporting CRLs, OCSP and attribute certificates | |
44 | - Multiple plugins providing crypto algorithms in software | |
45 | - CURL and OpenLDAP fetcher | |
a11ea97d | 46 | |
16f5dacd MW |
47 | - libstrongswan gained a relational database API which uses pluggable database |
48 | providers. Plugins for MySQL and SQLite are available. | |
49 | ||
50 | - The IKEv2 keying daemon charon is more extensible. Generic plugins may provide | |
51 | connection configuration, credentials and EAP methods or control the daemon. | |
52 | Existing code has been ported to plugins: | |
53 | - EAP-AKA, EAP-SIM, EAP-MD5 and EAP-Identity | |
54 | - stroke configuration, credential and control (compatible to pluto) | |
55 | - XML bases management protocol to control and query the daemon | |
56 | The following new plugins are available: | |
57 | - An experimental SQL configuration, credential and logging plugin on | |
58 | top of either MySQL or SQLite | |
59 | - A unit testing plugin to run tests at daemon startup | |
60 | ||
61 | - The authentication and credential framework in charon has been heavily | |
62 | refactored to support modular credential providers, proper | |
63 | CERTREQ/CERT payload exchanges and extensible authorization rules. | |
64 | ||
65 | - The framework of strongSwan Manager has envolved to the web application | |
66 | framework libfast (FastCGI Application Server w/ Templates) and is usable | |
67 | by other applications. | |

70 | strongswan-4.1.11 |
71 | ----------------- | |
fb6d76cd | 72 | |
a561f74d AS |
73 | - IKE rekeying in NAT situations did not inherit the NAT conditions |
74 | to the rekeyed IKE_SA so that the UDP encapsulation was lost with | |
75 | the next CHILD_SA rekeying. | |
76 | ||
77 | - Wrong type definition of the next_payload variable in id_payload.c | |
78 | caused an INVALID_SYNTAX error on PowerPC platforms. | |
fb6d76cd | 79 | |
e6b50b3f AS |
80 | - Implemented IKEv2 EAP-SIM server and client test modules that use |
81 | triplets stored in a file. For details on the configuration see | |
82 | the scenario 'ikev2/rw-eap-sim-rsa'. | |
83 | ||
fb6d76cd | 84 | |
83e0d841 AS |
85 | strongswan-4.1.10 |
86 | ----------------- | |
87 | ||
88 | - Fixed error in the ordering of the certinfo_t records in the ocsp cache that | |
89 | caused multiple entries of the same serial number to be created. | |
90 | ||
fdc7c943 MW |
91 | - Implementation of a simple EAP-MD5 module which provides CHAP |
92 | authentication. This may be interesting in conjunction with certificate | |
93 | based server authentication, as weak passwords can't be brute forced | |
94 | (in contradiction to traditional IKEv2 PSK). | |
95 | ||
96 | - A complete software based implementation of EAP-AKA, using algorithms | |
97 | specified in 3GPP2 (S.S0055). This implementation does not use an USIM, | |
98 | but reads the secrets from ipsec.secrets. Make sure to read eap_aka.h | |
99 | before using it. | |
100 | ||
101 | - Support for vendor specific EAP methods using Expanded EAP types. The | |
102 | interface to EAP modules has been slightly changed, so make sure to | |
103 | check the changes if you're already rolling your own modules. | |

106 | strongswan-4.1.9 |
107 | ---------------- | |
108 | ||
800b3356 AS |
109 | - The default _updown script now dynamically inserts and removes ip6tables |
110 | firewall rules if leftfirewall=yes is set in IPv6 connections. New IPv6 | |
111 | net-net and roadwarrior (PSK/RSA) scenarios for both IKEv1 and IKEV2 were | |
112 | added. | |
5076770c | 113 | |
6f274c2a MW |
114 | - Implemented RFC4478 repeated authentication to force EAP/Virtual-IP clients |
115 | to reestablish an IKE_SA within a given timeframe. | |
116 | ||
117 | - strongSwan Manager supports configuration listing, initiation and termination | |
118 | of IKE and CHILD_SAs. | |
119 | ||
120 | - Fixes and improvements to multithreading code. | |
121 | ||
8b678ad4 MW |
122 | - IKEv2 plugins have been renamed to libcharon-* to avoid naming conflicts. |
123 | Make sure to remove the old plugins in $libexecdir/ipsec, otherwise they get | |
124 | loaded twice. | |
5076770c | 125 | |
83e0d841 | 126 | |
b82e8231 AS |
127 | strongswan-4.1.8 |
128 | ---------------- | |
129 | ||
5076770c | 130 | - Removed recursive pthread mutexes since uClibc doesn't support them. |
b82e8231 AS |
131 | |
132 | ||
a4a3632c AS |
133 | strongswan-4.1.7 |
134 | ---------------- | |
135 | ||
136 | - In NAT traversal situations and multiple queued Quick Modes, | |
137 | those pending connections inserted by auto=start after the | |
138 | port floating from 500 to 4500 were erronously deleted. | |
139 | ||
6e193274 | 140 | - Added a "forceencaps" connection parameter to enforce UDP encapsulation |
078b6008 | 141 | to surmount restrictive firewalls. NAT detection payloads are faked to |
6e193274 MW |
142 | simulate a NAT situation and trick the other peer into NAT mode (IKEv2 only). |
143 | ||
144 | - Preview of strongSwan Manager, a web based configuration and monitoring | |
145 | application. It uses a new XML control interface to query the IKEv2 daemon | |
146 | (see http://trac.strongswan.org/wiki/Manager). | |
147 | ||
148 | - Experimental SQLite configuration backend which will provide the configuration | |
149 | interface for strongSwan Manager in future releases. | |
150 | ||
151 | - Further improvements to MOBIKE support. | |
152 | ||
a4a3632c | 153 | |
3dcf9dbd AS |
154 | strongswan-4.1.6 |
155 | ---------------- | |
156 | ||
3eac4dfd AS |
157 | - Since some third party IKEv2 implementations run into |
158 | problems with strongSwan announcing MOBIKE capability per | |
159 | default, MOBIKE can be disabled on a per-connection-basis | |
160 | using the mobike=no option. Whereas mobike=no disables the | |
161 | sending of the MOBIKE_SUPPORTED notification and the floating | |
162 | to UDP port 4500 with the IKE_AUTH request even if no NAT | |
163 | situation has been detected, strongSwan will still support | |
164 | MOBIKE acting as a responder. | |
165 | ||
166 | - the default ipsec routing table plus its corresponding priority | |
167 | used for inserting source routes has been changed from 100 to 220. | |
168 | It can be configured using the --with-ipsec-routing-table and | |
169 | --with-ipsec-routing-table-prio options. | |
170 | ||
bdc0b55b AS |
171 | - the --enable-integrity-test configure option tests the |
172 | integrity of the libstrongswan crypto code during the charon | |
173 | startup. | |
174 | ||
3eac4dfd AS |
175 | - the --disable-xauth-vid configure option disables the sending |
176 | of the XAUTH vendor ID. This can be used as a workaround when | |
177 | interoperating with some Windows VPN clients that get into | |
178 | trouble upon reception of an XAUTH VID without eXtended | |
179 | AUTHentication having been configured. | |
180 | ||
f872f9d1 AS |
181 | - ipsec stroke now supports the rereadsecrets, rereadaacerts, |
182 | rereadacerts, and listacerts options. | |
3dcf9dbd AS |
183 | |
184 | ||
7ad634a2 AS |
185 | strongswan-4.1.5 |
186 | ---------------- | |
187 | ||
188 | - If a DNS lookup failure occurs when resolving right=%<FQDN> | |
189 | or right=<FQDN> combined with rightallowany=yes then the | |
190 | connection is not updated by ipsec starter thus preventing | |
191 | the disruption of an active IPsec connection. Only if the DNS | |
192 | lookup successfully returns with a changed IP address the | |
193 | corresponding connection definition is updated. | |
194 | ||
8f5b363c MW |
195 | - Routes installed by the keying daemons are now in a separate |
196 | routing table with the ID 100 to avoid conflicts with the main | |
197 | table. Route lookup for IKEv2 traffic is done in userspace to ignore | |
198 | routes installed for IPsec, as IKE traffic shouldn't get encapsulated. | |
199 | ||
7ad634a2 | 200 | |
e93c68ba AS |
201 | strongswan-4.1.4 |
202 | ---------------- | |
203 | ||
204 | - The pluto IKEv1 daemon now exhibits the same behaviour as its | |
205 | IKEv2 companion charon by inserting an explicit route via the | |
206 | _updown script only if a sourceip exists. This is admissible | |
207 | since routing through the IPsec tunnel is handled automatically | |
b7af55ac AS |
208 | by NETKEY's IPsec policies. As a consequence the left|rightnexthop |
209 | parameter is not required any more. | |
078ce348 AS |
210 | |
211 | - The new IKEv1 parameter right|leftallowany parameters helps to handle | |
212 | the case where both peers possess dynamic IP addresses that are | |
213 | usually resolved using DynDNS or a similar service. The configuration | |
214 | ||
215 | right=peer.foo.bar | |
216 | rightallowany=yes | |
217 | ||
218 | can be used by the initiator to start up a connection to a peer | |
219 | by resolving peer.foo.bar into the currently allocated IP address. | |
220 | Thanks to the rightallowany flag the connection behaves later on | |
221 | as | |
222 | ||
223 | right=%any | |
224 | ||
225 | so that the peer can rekey the connection as an initiator when his | |
1fbdab85 AS |
226 | IP address changes. An alternative notation is |
227 | ||
228 | right=%peer.foo.bar | |
229 | ||
230 | which will implicitly set rightallowany=yes. | |
231 | ||
232 | - ipsec starter now fails more gracefully in the presence of parsing | |
233 | errors. Flawed ca and conn section are discarded and pluto is started | |
234 | if non-fatal errors only were encountered. If right=%peer.foo.bar | |
235 | cannot be resolved by DNS then right=%any will be used so that passive | |
236 | connections as a responder are still possible. | |
078ce348 | 237 | |
a0a0bdd7 AS |
238 | - The new pkcs11initargs parameter that can be placed in the |
239 | setup config section of /etc/ipsec.conf allows the definition | |
240 | of an argument string that is used with the PKCS#11 C_Initialize() | |
241 | function. This non-standard feature is required by the NSS softoken | |
242 | library. This patch was contributed by Robert Varga. | |
243 | ||
244 | - Fixed a bug in ipsec starter introduced by strongswan-2.8.5 | |
245 | which caused a segmentation fault in the presence of unknown | |
246 | or misspelt keywords in ipsec.conf. This bug fix was contributed | |
247 | by Robert Varga. | |
248 | ||
e3606f2b MW |
249 | - Partial support for MOBIKE in IKEv2. The initiator acts on interface/ |
250 | address configuration changes and updates IKE and IPsec SAs dynamically. | |
e93c68ba | 251 | |
06651827 | 252 | |
a3354a69 AS |
253 | strongswan-4.1.3 |
254 | ---------------- | |
255 | ||
41e16cf4 | 256 | - IKEv2 peer configuration selection now can be based on a given |
35d4809c AS |
257 | certification authority using the rightca= statement. |
258 | ||
259 | - IKEv2 authentication based on RSA signatures now can handle multiple | |
41e16cf4 AS |
260 | certificates issued for a given peer ID. This allows a smooth transition |
261 | in the case of a peer certificate renewal. | |
a3354a69 | 262 | |
998ca0ea MW |
263 | - IKEv2: Support for requesting a specific virtual IP using leftsourceip on the |
264 | client and returning requested virtual IPs using rightsourceip=%config | |
265 | on the server. If the server does not support configuration payloads, the | |
266 | client enforces its leftsourceip parameter. | |
267 | ||
268 | - The ./configure options --with-uid/--with-gid allow pluto and charon | |
269 | to drop their privileges to a minimum and change to an other UID/GID. This | |
270 | improves the systems security, as a possible intruder may only get the | |
271 | CAP_NET_ADMIN capability. | |
272 | ||
273 | - Further modularization of charon: Pluggable control interface and | |
274 | configuration backend modules provide extensibility. The control interface | |
275 | for stroke is included, and further interfaces using DBUS (NetworkManager) | |
276 | or XML are on the way. A backend for storing configurations in the daemon | |
277 | is provided and more advanced backends (using e.g. a database) are trivial | |
278 | to implement. | |
a3354a69 | 279 | |
41e16cf4 AS |
280 | - Fixed a compilation failure in libfreeswan occuring with Linux kernel |
281 | headers > 2.6.17. | |
282 | ||
283 | ||
8ea7b96f AS |
284 | strongswan-4.1.2 |
285 | ---------------- | |
286 | ||
e23d98a7 | 287 | - Support for an additional Diffie-Hellman exchange when creating/rekeying |
37fb0355 MW |
288 | a CHILD_SA in IKEv2 (PFS). PFS is enabled when the proposal contains a |
289 | DH group (e.g. "esp=aes128-sha1-modp1536"). Further, DH group negotiation | |
290 | is implemented properly for rekeying. | |
291 | ||
292 | - Support for the AES-XCBC-96 MAC algorithm for IPsec SAs when using IKEv2 | |
293 | (requires linux >= 2.6.20). It is enabled using e.g. "esp=aes256-aesxcbc". | |
294 | ||
d931f465 MW |
295 | - Working IPv4-in-IPv6 and IPv6-in-IPv4 tunnels for linux >= 2.6.21. |
296 | ||
37fb0355 MW |
297 | - Added support for EAP modules which do not establish an MSK. |
298 | ||
dfbe2a0f | 299 | - Removed the dependencies from the /usr/include/linux/ headers by |
9f78f957 | 300 | including xfrm.h, ipsec.h, and pfkeyv2.h in the distribution. |
dfbe2a0f | 301 | |
9f78f957 AS |
302 | - crlNumber is now listed by ipsec listcrls |
303 | ||
8ea7b96f AS |
304 | - The xauth_modules.verify_secret() function now passes the |
305 | connection name. | |
306 | ||
e23d98a7 | 307 | |
ed284399 MW |
308 | strongswan-4.1.1 |
309 | ---------------- | |
310 | ||
311 | - Server side cookie support. If to may IKE_SAs are in CONNECTING state, | |
312 | cookies are enabled and protect against DoS attacks with faked source | |
313 | addresses. Number of IKE_SAs in CONNECTING state is also limited per | |
314 | peer address to avoid resource exhaustion. IKE_SA_INIT messages are | |
315 | compared to properly detect retransmissions and incoming retransmits are | |
316 | detected even if the IKE_SA is blocked (e.g. doing OCSP fetches). | |
317 | ||
db88e37d AS |
318 | - The IKEv2 daemon charon now supports dynamic http- and ldap-based CRL |
319 | fetching enabled by crlcheckinterval > 0 and caching fetched CRLs | |
320 | enabled by cachecrls=yes. | |
321 | ||
3b4f7d92 AS |
322 | - Added the configuration options --enable-nat-transport which enables |
323 | the potentially insecure NAT traversal for IPsec transport mode and | |
324 | --disable-vendor-id which disables the sending of the strongSwan | |
325 | vendor ID. | |
326 | ||
327 | - Fixed a long-standing bug in the pluto IKEv1 daemon which caused | |
328 | a segmentation fault if a malformed payload was detected in the | |
329 | IKE MR2 message and pluto tried to send an encrypted notification | |
330 | message. | |
331 | ||
46b9ff68 AS |
332 | - Added the NATT_IETF_02_N Vendor ID in order to support IKEv1 connections |
333 | with Windows 2003 Server which uses a wrong VID hash. | |
334 | ||
3b4f7d92 | 335 | |
34bbd0c3 | 336 | strongswan-4.1.0 |
cd3958f8 AS |
337 | ---------------- |
338 | ||
339 | - Support of SHA2_384 hash function for protecting IKEv1 | |
340 | negotiations and support of SHA2 signatures in X.509 certificates. | |
341 | ||
342 | - Fixed a serious bug in the computation of the SHA2-512 HMAC | |
343 | function. Introduced automatic self-test of all IKEv1 hash | |
344 | and hmac functions during pluto startup. Failure of a self-test | |
345 | currently issues a warning only but does not exit pluto [yet]. | |
346 | ||
9b45443d MW |
347 | - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2. |
348 | ||
c5d0fbb6 AS |
349 | - Full support of CA information sections. ipsec listcainfos |
350 | now shows all collected crlDistributionPoints and OCSP | |
351 | accessLocations. | |
352 | ||
69ed04bf AS |
353 | - Support of the Online Certificate Status Protocol (OCSP) for IKEv2. |
354 | This feature requires the HTTP fetching capabilities of the libcurl | |
355 | library which must be enabled by setting the --enable-http configure | |
356 | option. | |
357 | ||
9b45443d MW |
358 | - Refactored core of the IKEv2 message processing code, allowing better |
359 | code reuse and separation. | |
360 | ||
361 | - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration | |
362 | payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted | |
363 | by the requestor and installed in a resolv.conf file. | |
364 | ||
365 | - The IKEv2 daemon charon installs a route for each IPsec policy to use | |
366 | the correct source address even if an application does not explicitly | |
367 | specify it. | |
368 | ||
369 | - Integrated the EAP framework into charon which loads pluggable EAP library | |
370 | modules. The ipsec.conf parameter authby=eap initiates EAP authentication | |
371 | on the client side, while the "eap" parameter on the server side defines | |
372 | the EAP method to use for client authentication. | |
373 | A generic client side EAP-Identity module and an EAP-SIM authentication | |
374 | module using a third party card reader implementation are included. | |
375 | ||
376 | - Added client side support for cookies. | |
377 | ||
378 | - Integrated the fixes done at the IKEv2 interoperability bakeoff, including | |
379 | strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor | |
380 | fixes to enhance interoperability with other implementations. | |

383 | strongswan-4.0.7 |
384 | ---------------- | |
385 | ||
6fdf5f44 AS |
386 | - strongSwan now interoperates with the NCP Secure Entry Client, |
387 | the Shrew Soft VPN Client, and the Cisco VPN client, doing both | |
388 | XAUTH and Mode Config. | |
1c266d7d AS |
389 | |
390 | - UNITY attributes are now recognized and UNITY_BANNER is set | |
391 | to a default string. | |

394 | strongswan-4.0.6 |
395 | ---------------- | |
396 | ||
e38a15d4 AS |
397 | - IKEv1: Support for extended authentication (XAUTH) in combination |
398 | with ISAKMP Main Mode RSA or PSK authentication. Both client and | |
399 | server side were implemented. Handling of user credentials can | |
400 | be done by a run-time loadable XAUTH module. By default user | |
401 | credentials are stored in ipsec.secrets. | |
402 | ||
2b4405a3 MW |
403 | - IKEv2: Support for reauthentication when rekeying |
404 | ||
5903179b | 405 | - IKEv2: Support for transport mode |
af87afed | 406 | |
5903179b | 407 | - fixed a lot of bugs related to byte order |
2b4405a3 | 408 | |
5903179b | 409 | - various other bugfixes |
2b4405a3 MW |

412 | strongswan-4.0.5 |
413 | ---------------- | |
414 | ||
415 | - IKEv1: Implementation of ModeConfig push mode via the new connection | |
416 | keyword modeconfig=push allows interoperability with Cisco VPN gateways. | |
417 | ||
418 | - IKEv1: The command ipsec statusall now shows "DPD active" for all | |
419 | ISAKMP SAs that are under active Dead Peer Detection control. | |
420 | ||
421 | - IKEv2: Charon's logging and debugging framework has been completely rewritten. | |
422 | Instead of logger, special printf() functions are used to directly | |
423 | print objects like hosts (%H) identifications (%D), certificates (%Q), | |
424 | etc. The number of debugging levels have been reduced to: | |
03bf883d | 425 | |
0cd645d2 | 426 | 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private) |
03bf883d | 427 | |
0cd645d2 AS |
428 | The debugging levels can either be specified statically in ipsec.conf as |
429 | ||
430 | config setup | |
03bf883d | 431 | charondebug="lib 1, cfg 3, net 2" |
0cd645d2 | 432 | |
03bf883d | 433 | or changed at runtime via stroke as |
0cd645d2 | 434 | |
03bf883d | 435 | ipsec stroke loglevel cfg 2 |

438 | strongswan-4.0.4 |
439 | ---------------- | |
440 | ||
441 | - Implemented full support for IPv6-in-IPv6 tunnels. | |
442 | ||
443 | - Added configuration options for dead peer detection in IKEv2. dpd_action | |
444 | types "clear", "hold" and "restart" are supported. The dpd_timeout | |
445 | value is not used, as the normal retransmission policy applies to | |
446 | detect dead peers. The dpd_delay parameter enables sending of empty | |
447 | informational message to detect dead peers in case of inactivity. | |
448 | ||
449 | - Added support for preshared keys in IKEv2. PSK keys configured in | |
450 | ipsec.secrets are loaded. The authby parameter specifies the authentication | |
451 | method to authentificate ourself, the other peer may use PSK or RSA. | |
452 | ||
453 | - Changed retransmission policy to respect the keyingtries parameter. | |
454 | ||
112ad7c3 AS |
455 | - Added private key decryption. PEM keys encrypted with AES-128/192/256 |
456 | or 3DES are supported. | |
48dc3934 MW |
457 | |
458 | - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to | |
459 | encrypt IKE traffic. | |
460 | ||
461 | - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates | |
462 | signed with such a hash algorithm. | |
463 | ||
464 | - Added initial support for updown scripts. The actions up-host/client and | |
465 | down-host/client are executed. The leftfirewall=yes parameter | |
466 | uses the default updown script to insert dynamic firewall rules, a custom | |
467 | updown script may be specified with the leftupdown parameter. | |
468 | ||
469 | ||
a1310b6b MW |
470 | strongswan-4.0.3 |
471 | ---------------- | |
472 | ||
473 | - Added support for the auto=route ipsec.conf parameter and the | |
474 | ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and | |
475 | CHILD_SAs dynamically on demand when traffic is detected by the | |
476 | kernel. | |
477 | ||
478 | - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter. | |
479 | As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only | |
480 | new keys are generated using perfect forward secrecy. An optional flag | |
481 | which enforces reauthentication will be implemented later. | |
482 | ||
b425d998 AS |
483 | - "sha" and "sha1" are now treated as synonyms in the ike= and esp= |
484 | algorithm configuration statements. | |
485 | ||
486 | ||
bf4df11f AS |
487 | strongswan-4.0.2 |
488 | ---------------- | |
489 | ||
623d3dcf AS |
490 | - Full X.509 certificate trust chain verification has been implemented. |
491 | End entity certificates can be exchanged via CERT payloads. The current | |
492 | default is leftsendcert=always, since CERTREQ payloads are not supported | |
493 | yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls. | |
efa40c11 MW |
494 | |
495 | - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2 | |
496 | would offer more possibilities for traffic selection, but the Linux kernel | |
497 | currently does not support it. That's why we stick with these simple | |
498 | ipsec.conf rules for now. | |
499 | ||
623d3dcf AS |
500 | - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no |
501 | IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear, | |
502 | dpddelay=60s). | |
503 | ||
efa40c11 MW |
504 | - Initial NAT traversal support in IKEv2. Charon includes NAT detection |
505 | notify payloads to detect NAT routers between the peers. It switches | |
506 | to port 4500, uses UDP encapsulated ESP packets, handles peer address | |
507 | changes gracefully and sends keep alive message periodically. | |
508 | ||
509 | - Reimplemented IKE_SA state machine for charon, which allows simultaneous | |
510 | rekeying, more shared code, cleaner design, proper retransmission | |
511 | and a more extensible code base. | |
512 | ||
cfd8b27f AS |
513 | - The mixed PSK/RSA roadwarrior detection capability introduced by the |
514 | strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal | |
515 | payloads by the responder right before any defined IKE Main Mode state had | |
516 | been established. Although any form of bad proposal syntax was being correctly | |
517 | detected by the payload parser, the subsequent error handler didn't check | |
518 | the state pointer before logging current state information, causing an | |
519 | immediate crash of the pluto keying daemon due to a NULL pointer. | |
520 | ||
bf4df11f | 521 | |
7e81e975 MW |
522 | strongswan-4.0.1 |
523 | ---------------- | |
524 | ||
c15c3d4b MW |
525 | - Added algorithm selection to charon: New default algorithms for |
526 | ike=aes128-sha-modp2048, as both daemons support it. The default | |
527 | for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles | |
528 | the ike/esp parameter the same way as pluto. As this syntax does | |
529 | not allow specification of a pseudo random function, the same | |
530 | algorithm as for integrity is used (currently sha/md5). Supported | |
531 | algorithms for IKE: | |
532 | Encryption: aes128, aes192, aes256 | |
533 | Integrity/PRF: md5, sha (using hmac) | |
534 | DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192 | |
535 | and for ESP: | |
536 | Encryption: aes128, aes192, aes256, 3des, blowfish128, | |
537 | blowfish192, blowfish256 | |
538 | Integrity: md5, sha1 | |
539 | More IKE encryption algorithms will come after porting libcrypto into | |
540 | libstrongswan. | |
f2c2d395 | 541 | |
c15c3d4b MW |
542 | - initial support for rekeying CHILD_SAs using IKEv2. Currently no |
543 | perfect forward secrecy is used. The rekeying parameters rekey, | |
22ff6f57 | 544 | rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported |
c15c3d4b MW |
545 | when using IKEv2. WARNING: charon currently is unable to handle |
546 | simultaneous rekeying. To avoid such a situation, use a large | |
547 | rekeyfuzz, or even better, set rekey=no on one peer. | |
22ff6f57 | 548 | |
7e81e975 MW |
549 | - support for host2host, net2net, host2net (roadwarrior) tunnels |
550 | using predefined RSA certificates (see uml scenarios for | |
551 | configuration examples). | |
552 | ||
f2c2d395 MW |
553 | - new build environment featuring autotools. Features such |
554 | as HTTP, LDAP and smartcard support may be enabled using | |
555 | the ./configure script. Changing install directories | |
556 | is possible, too. See ./configure --help for more details. | |
557 | ||
22ff6f57 MW |
558 | - better integration of charon with ipsec starter, which allows |
559 | (almost) transparent operation with both daemons. charon | |
560 | handles ipsec commands up, down, status, statusall, listall, | |
561 | listcerts and allows proper load, reload and delete of connections | |
562 | via ipsec starter. | |
563 | ||
b425d998 | 564 | |
9820c0e2 MW |
565 | strongswan-4.0.0 |
566 | ---------------- | |
567 | ||
568 | - initial support of the IKEv2 protocol. Connections in | |
569 | ipsec.conf designated by keyexchange=ikev2 are negotiated | |
570 | by the new IKEv2 charon keying daemon whereas those marked | |
571 | by keyexchange=ikev1 or the default keyexchange=ike are | |
572 | handled thy the IKEv1 pluto keying daemon. Currently only | |
573 | a limited subset of functions are available with IKEv2 | |
574 | (Default AES encryption, authentication based on locally | |
575 | imported X.509 certificates, unencrypted private RSA keys | |
576 | in PKCS#1 file format, limited functionality of the ipsec | |
577 | status command). | |
578 | ||
579 | ||
997358a6 MW |
580 | strongswan-2.7.0 |
581 | ---------------- | |
582 | ||
583 | - the dynamic iptables rules from the _updown_x509 template | |
584 | for KLIPS and the _updown_policy template for NETKEY have | |
585 | been merged into the default _updown script. The existing | |
586 | left|rightfirewall keyword causes the automatic insertion | |
587 | and deletion of ACCEPT rules for tunneled traffic upon | |
588 | the successful setup and teardown of an IPsec SA, respectively. | |
589 | left|rightfirwall can be used with KLIPS under any Linux 2.4 | |
590 | kernel or with NETKEY under a Linux kernel version >= 2.6.16 | |
591 | in conjuction with iptables >= 1.3.5. For NETKEY under a Linux | |
592 | kernel version < 2.6.16 which does not support IPsec policy | |
593 | matching yet, please continue to use a copy of the _updown_espmark | |
594 | template loaded via the left|rightupdown keyword. | |
595 | ||
596 | - a new left|righthostaccess keyword has been introduced which | |
597 | can be used in conjunction with left|rightfirewall and the | |
598 | default _updown script. By default leftfirewall=yes inserts | |
599 | a bi-directional iptables FORWARD rule for a local client network | |
600 | with a netmask different from 255.255.255.255 (single host). | |
601 | This does not allow to access the VPN gateway host via its | |
602 | internal network interface which is part of the client subnet | |
603 | because an iptables INPUT and OUTPUT rule would be required. | |
604 | lefthostaccess=yes will cause this additional ACCEPT rules to | |
605 | be inserted. | |
606 | ||
607 | - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal | |
608 | payload is preparsed in order to find out whether the roadwarrior | |
609 | requests PSK or RSA so that a matching connection candidate can | |
610 | be found. | |
611 | ||
612 | ||
613 | strongswan-2.6.4 | |
614 | ---------------- | |
615 | ||
616 | - the new _updown_policy template allows ipsec policy based | |
617 | iptables firewall rules. Required are iptables version | |
618 | >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes | |
619 | the _updown_espmark template, so that no INPUT mangle rules | |
620 | are required any more. | |
621 | ||
622 | - added support of DPD restart mode | |
623 | ||
624 | - ipsec starter now allows the use of wildcards in include | |
625 | statements as e.g. in "include /etc/my_ipsec/*.conf". | |
626 | Patch courtesy of Matthias Haas. | |
627 | ||
628 | - the Netscape OID 'employeeNumber' is now recognized and can be | |
629 | used as a Relative Distinguished Name in certificates. | |
630 | ||
631 | ||
632 | strongswan-2.6.3 | |
633 | ---------------- | |
634 | ||
635 | - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec | |
636 | command and not of ipsec setup any more. | |
637 | ||
638 | - ipsec starter now supports AH authentication in conjunction with | |
639 | ESP encryption. AH authentication is configured in ipsec.conf | |
640 | via the auth=ah parameter. | |
641 | ||
642 | - The command ipsec scencrypt|scdecrypt <args> is now an alias for | |
643 | ipsec whack --scencrypt|scdecrypt <args>. | |
644 | ||
645 | - get_sa_info() now determines for the native netkey IPsec stack | |
646 | the exact time of the last use of an active eroute. This information | |
647 | is used by the Dead Peer Detection algorithm and is also displayed by | |
648 | the ipsec status command. | |
649 | ||
650 | ||
651 | strongswan-2.6.2 | |
652 | ---------------- | |
653 | ||
654 | - running under the native Linux 2.6 IPsec stack, the function | |
655 | get_sa_info() is called by ipsec auto --status to display the current | |
656 | number of transmitted bytes per IPsec SA. | |
657 | ||
658 | - get_sa_info() is also used by the Dead Peer Detection process to detect | |
659 | recent ESP activity. If ESP traffic was received from the peer within | |
660 | the last dpd_delay interval then no R_Y_THERE notification must be sent. | |
661 | ||
662 | - strongSwan now supports the Relative Distinguished Name "unstructuredName" | |
663 | in ID_DER_ASN1_DN identities. The following notations are possible: | |
664 | ||
665 | rightid="unstructuredName=John Doe" | |
666 | rightid="UN=John Doe" | |
667 | ||
668 | - fixed a long-standing bug which caused PSK-based roadwarrior connections | |
669 | to segfault in the function id.c:same_id() called by keys.c:get_secret() | |
670 | if an FQDN, USER_FQDN, or Key ID was defined, as in the following example. | |
671 | ||
672 | conn rw | |
673 | right=%any | |
674 | rightid=@foo.bar | |
675 | authby=secret | |
676 | ||
677 | - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall). | |
678 | ||
679 | - ipsec starter didn't set host_addr and client.addr ports in whack msg. | |
680 | ||
681 | - in order to guarantee backwards-compatibility with the script-based | |
682 | auto function (e.g. auto --replace), the ipsec starter scripts stores | |
683 | the defaultroute information in the temporary file /var/run/ipsec.info. | |
684 | ||
685 | - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH | |
686 | Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config | |
687 | servers. | |
688 | ||
689 | - the ipsec starter now also recognizes the parameters authby=never and | |
690 | type=passthrough|pass|drop|reject. | |
691 | ||
692 | ||
693 | strongswan-2.6.1 | |
694 | ---------------- | |
695 | ||
696 | - ipsec starter now supports the also parameter which allows | |
697 | a modular structure of the connection definitions. Thus | |
698 | "ipsec start" is now ready to replace "ipsec setup". | |
699 | ||
700 | ||
701 | strongswan-2.6.0 | |
702 | ---------------- | |
703 | ||
704 | - Mathieu Lafon's popular ipsec starter tool has been added to the | |
705 | strongSwan distribution. Many thanks go to Stephan Scholz from astaro | |
706 | for his integration work. ipsec starter is a C program which is going | |
707 | to replace the various shell and awk starter scripts (setup, _plutoload, | |
708 | _plutostart, _realsetup, _startklips, _confread, and auto). Since | |
709 | ipsec.conf is now parsed only once, the starting of multiple tunnels is | |
710 | accelerated tremedously. | |
711 | ||
712 | - Added support of %defaultroute to the ipsec starter. If the IP address | |
713 | changes, a HUP signal to the ipsec starter will automatically | |
714 | reload pluto's connections. | |
715 | ||
716 | - moved most compile time configurations from pluto/Makefile to | |
717 | Makefile.inc by defining the options USE_LIBCURL, USE_LDAP, | |
718 | USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE. | |
719 | ||
720 | - removed the ipsec verify and ipsec newhostkey commands | |
721 | ||
722 | - fixed some 64-bit issues in formatted print statements | |
723 | ||
724 | - The scepclient functionality implementing the Simple Certificate | |
725 | Enrollment Protocol (SCEP) is nearly complete but hasn't been | |
726 | documented yet. | |
727 | ||
728 | ||
729 | strongswan-2.5.7 | |
730 | ---------------- | |
731 | ||
732 | - CA certicates are now automatically loaded from a smartcard | |
733 | or USB crypto token and appear in the ipsec auto --listcacerts | |
734 | listing. | |
735 | ||
736 | ||
737 | strongswan-2.5.6 | |
738 | ---------------- | |
739 | ||
740 | - when using "ipsec whack --scencrypt <data>" with a PKCS#11 | |
741 | library that does not support the C_Encrypt() Cryptoki | |
742 | function (e.g. OpenSC), the RSA encryption is done in | |
743 | software using the public key fetched from the smartcard. | |
744 | ||
745 | - The scepclient function now allows to define the | |
746 | validity of a self-signed certificate using the --days, | |
747 | --startdate, and --enddate options. The default validity | |
748 | has been changed from one year to five years. | |
749 | ||
750 | ||
751 | strongswan-2.5.5 | |
752 | ---------------- | |
753 | ||
754 | - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11 | |
755 | interface to other applications for RSA encryption and decryption | |
756 | via the whack interface. Notation: | |
757 | ||
758 | ipsec whack --scencrypt <data> | |
759 | [--inbase 16|hex|64|base64|256|text|ascii] | |
760 | [--outbase 16|hex|64|base64|256|text|ascii] | |
761 | [--keyid <keyid>] | |
762 | ||
763 | ipsec whack --scdecrypt <data> | |
764 | [--inbase 16|hex|64|base64|256|text|ascii] | |
765 | [--outbase 16|hex|64|base64|256|text|ascii] | |
766 | [--keyid <keyid>] | |
767 | ||
768 | The default setting for inbase and outbase is hex. | |
769 | ||
770 | The new proxy interface can be used for securing symmetric | |
771 | encryption keys required by the cryptoloop or dm-crypt | |
772 | disk encryption schemes, especially in the case when | |
773 | pkcs11keepstate=yes causes pluto to lock the pkcs11 slot | |
774 | permanently. | |
775 | ||
776 | - if the file /etc/ipsec.secrets is lacking during the startup of | |
777 | pluto then the root-readable file /etc/ipsec.d/private/myKey.der | |
778 | containing a 2048 bit RSA private key and a matching self-signed | |
779 | certificate stored in the file /etc/ipsec.d/certs/selfCert.der | |
780 | is automatically generated by calling the function | |
781 | ||
782 | ipsec scepclient --out pkcs1 --out cert-self | |
783 | ||
784 | scepclient was written by Jan Hutter and Martin Willi, students | |
785 | at the University of Applied Sciences in Rapperswil, Switzerland. | |
786 | ||
787 | ||
788 | strongswan-2.5.4 | |
789 | ---------------- | |
790 | ||
791 | - the current extension of the PKCS#7 framework introduced | |
792 | a parsing error in PKCS#7 wrapped X.509 certificates that are | |
793 | e.g. transmitted by Windows XP when multi-level CAs are used. | |
794 | the parsing syntax has been fixed. | |
795 | ||
796 | - added a patch by Gerald Richter which tolerates multiple occurrences | |
797 | of the ipsec0 interface when using KLIPS. | |
798 | ||
799 | ||
800 | strongswan-2.5.3 | |
801 | ---------------- | |
802 | ||
803 | - with gawk-3.1.4 the word "default2 has become a protected | |
804 | keyword for use in switch statements and cannot be used any | |
805 | more in the strongSwan scripts. This problem has been | |
806 | solved by renaming "default" to "defaults" and "setdefault" | |
807 | in the scripts _confread and auto, respectively. | |
808 | ||
809 | - introduced the parameter leftsendcert with the values | |
810 | ||
811 | always|yes (the default, always send a cert) | |
812 | ifasked (send the cert only upon a cert request) | |
813 | never|no (never send a cert, used for raw RSA keys and | |
814 | self-signed certs) | |
815 | ||
816 | - fixed the initialization of the ESP key length to a default of | |
817 | 128 bits in the case that the peer does not send a key length | |
818 | attribute for AES encryption. | |
819 | ||
820 | - applied Herbert Xu's uniqueIDs patch | |
821 | ||
822 | - applied Herbert Xu's CLOEXEC patches | |
823 | ||
824 | ||
825 | strongswan-2.5.2 | |
826 | ---------------- | |
827 | ||
828 | - CRLs can now be cached also in the case when the issuer's | |
829 | certificate does not contain a subjectKeyIdentifier field. | |
830 | In that case the subjectKeyIdentifier is computed by pluto as the | |
831 | 160 bit SHA-1 hash of the issuer's public key in compliance | |
832 | with section 4.2.1.2 of RFC 3280. | |
833 | ||
834 | - Fixed a bug introduced by strongswan-2.5.1 which eliminated | |
835 | not only multiple Quick Modes of a given connection but also | |
836 | multiple connections between two security gateways. | |
837 | ||
838 | ||
839 | strongswan-2.5.1 | |
840 | ---------------- | |
841 | ||
842 | - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute | |
843 | installed either by setting auto=route in ipsec.conf or by | |
844 | a connection put into hold, generates an XFRM_AQUIRE event | |
845 | for each packet that wants to use the not-yet exisiting | |
846 | tunnel. Up to now each XFRM_AQUIRE event led to an entry in | |
847 | the Quick Mode queue, causing multiple IPsec SA to be | |
848 | established in rapid succession. Starting with strongswan-2.5.1 | |
849 | only a single IPsec SA is established per host-pair connection. | |
850 | ||
851 | - Right after loading the PKCS#11 module, all smartcard slots are | |
852 | searched for certificates. The result can be viewed using | |
853 | the command | |
854 | ||
855 | ipsec auto --listcards | |
856 | ||
857 | The certificate objects found in the slots are numbered | |
858 | starting with #1, #2, etc. This position number can be used to address | |
859 | certificates (leftcert=%smartcard) and keys (: PIN %smartcard) | |
860 | in ipsec.conf and ipsec.secrets, respectively: | |
861 | ||
862 | %smartcard (selects object #1) | |
863 | %smartcard#1 (selects object #1) | |
864 | %smartcard#3 (selects object #3) | |
865 | ||
866 | As an alternative the existing retrieval scheme can be used: | |
867 | ||
868 | %smartcard:45 (selects object with id=45) | |
869 | %smartcard0 (selects first object in slot 0) | |
870 | %smartcard4:45 (selects object in slot 4 with id=45) | |
871 | ||
872 | - Depending on the settings of CKA_SIGN and CKA_DECRYPT | |
873 | private key flags either C_Sign() or C_Decrypt() is used | |
874 | to generate a signature. | |
875 | ||
876 | - The output buffer length parameter siglen in C_Sign() | |
877 | is now initialized to the actual size of the output | |
878 | buffer prior to the function call. This fixes the | |
879 | CKR_BUFFER_TOO_SMALL error that could occur when using | |
880 | the OpenSC PKCS#11 module. | |
881 | ||
882 | - Changed the initialization of the PKCS#11 CK_MECHANISM in | |
883 | C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }. | |
884 | ||
885 | - Refactored the RSA public/private key code and transferred it | |
886 | from keys.c to the new pkcs1.c file as a preparatory step | |
887 | towards the release of the SCEP client. | |
888 | ||
889 | ||
890 | strongswan-2.5.0 | |
891 | ---------------- | |
892 | ||
893 | - The loading of a PKCS#11 smartcard library module during | |
894 | runtime does not require OpenSC library functions any more | |
895 | because the corresponding code has been integrated into | |
896 | smartcard.c. Also the RSAREF pkcs11 header files have been | |
897 | included in a newly created pluto/rsaref directory so that | |
898 | no external include path has to be defined any longer. | |
899 | ||
900 | - A long-awaited feature has been implemented at last: | |
901 | The local caching of CRLs fetched via HTTP or LDAP, activated | |
902 | by the parameter cachecrls=yes in the config setup section | |
903 | of ipsec.conf. The dynamically fetched CRLs are stored under | |
904 | a unique file name containing the issuer's subjectKeyID | |
905 | in /etc/ipsec.d/crls. | |
906 | ||
907 | - Applied a one-line patch courtesy of Michael Richardson | |
908 | from the Openswan project which fixes the kernel-oops | |
909 | in KLIPS when an snmp daemon is running on the same box. | |
910 | ||
911 | ||
912 | strongswan-2.4.4 | |
913 | ---------------- | |
914 | ||
915 | - Eliminated null length CRL distribution point strings. | |
916 | ||
917 | - Fixed a trust path evaluation bug introduced with 2.4.3 | |
918 | ||
919 | ||
920 | strongswan-2.4.3 | |
921 | ---------------- | |
922 | ||
923 | - Improved the joint OCSP / CRL revocation policy. | |
924 | OCSP responses have precedence over CRL entries. | |
925 | ||
926 | - Introduced support of CRLv2 reason codes. | |
927 | ||
928 | - Fixed a bug with key-pad equipped readers which caused | |
929 | pluto to prompt for the pin via the console when the first | |
930 | occasion to enter the pin via the key-pad was missed. | |
931 | ||
932 | - When pluto is built with LDAP_V3 enabled, the library | |
933 | liblber required by newer versions of openldap is now | |
934 | included. | |
935 | ||
936 | ||
937 | strongswan-2.4.2 | |
938 | ---------------- | |
939 | ||
940 | - Added the _updown_espmark template which requires all | |
941 | incoming ESP traffic to be marked with a default mark | |
942 | value of 50. | |
943 | ||
944 | - Introduced the pkcs11keepstate parameter in the config setup | |
945 | section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11 | |
946 | session and login states are kept as long as possible during | |
947 | the lifetime of pluto. This means that a PIN entry via a key | |
948 | pad has to be done only once. | |
949 | ||
950 | - Introduced the pkcs11module parameter in the config setup | |
951 | section of ipsec.conf which specifies the PKCS#11 module | |
952 | to be used with smart cards. Example: | |
953 | ||
954 | pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo | |
955 | ||
956 | - Added support of smartcard readers equipped with a PIN pad. | |
957 | ||
958 | - Added patch by Jay Pfeifer which detects when netkey | |
959 | modules have been statically built into the Linux 2.6 kernel. | |
960 | ||
961 | - Added two patches by Herbert Xu. The first uses ip xfrm | |
962 | instead of setkey to flush the IPsec policy database. The | |
963 | second sets the optional flag in inbound IPComp SAs only. | |
964 | ||
965 | - Applied Ulrich Weber's patch which fixes an interoperability | |
966 | problem between native IPsec and KLIPS systems caused by | |
967 | setting the replay window to 32 instead of 0 for ipcomp. | |
968 | ||
969 | ||
970 | strongswan-2.4.1 | |
971 | ---------------- | |
972 | ||
973 | - Fixed a bug which caused an unwanted Mode Config request | |
974 | to be initiated in the case where "right" was used to denote | |
975 | the local side in ipsec.conf and "left" the remote side, | |
976 | contrary to the recommendation that "right" be remote and | |
977 | "left" be"local". | |
978 | ||
979 | ||
980 | strongswan-2.4.0a | |
981 | ----------------- | |
982 | ||
983 | - updated Vendor ID to strongSwan-2.4.0 | |
984 | ||
985 | - updated copyright statement to include David Buechi and | |
986 | Michael Meier | |
987 | ||
988 | ||
989 | strongswan-2.4.0 | |
990 | ---------------- | |
991 | ||
992 | - strongSwan now communicates with attached smartcards and | |
993 | USB crypto tokens via the standardized PKCS #11 interface. | |
994 | By default the OpenSC library from www.opensc.org is used | |
995 | but any other PKCS#11 library could be dynamically linked. | |
996 | strongSwan's PKCS#11 API was implemented by David Buechi | |
997 | and Michael Meier, both graduates of the Zurich University | |
998 | of Applied Sciences in Winterthur, Switzerland. | |
999 | ||
1000 | - When a %trap eroute is triggered by an outgoing IP packet | |
1001 | then the native IPsec stack of the Linux 2.6 kernel [often/ | |
1002 | always?] returns an XFRM_ACQUIRE message with an undefined | |
1003 | protocol family field and the connection setup fails. | |
1004 | As a workaround IPv4 (AF_INET) is now assumed. | |
1005 | ||
1006 | - the results of the UML test scenarios are now enhanced | |
1007 | with block diagrams of the virtual network topology used | |
1008 | in a particular test. | |
1009 | ||
1010 | ||
1011 | strongswan-2.3.2 | |
1012 | ---------------- | |
1013 | ||
1014 | - fixed IV used to decrypt informational messages. | |
1015 | This bug was introduced with Mode Config functionality. | |
1016 | ||
1017 | - fixed NCP Vendor ID. | |
1018 | ||
1019 | - undid one of Ulrich Weber's maximum udp size patches | |
1020 | because it caused a segmentation fault with NAT-ed | |
1021 | Delete SA messages. | |
1022 | ||
1023 | - added UML scenarios wildcards and attr-cert which | |
1024 | demonstrate the implementation of IPsec policies based | |
1025 | on wildcard parameters contained in Distinguished Names and | |
1026 | on X.509 attribute certificates, respectively. | |
1027 | ||
1028 | ||
1029 | strongswan-2.3.1 | |
1030 | ---------------- | |
1031 | ||
1032 | - Added basic Mode Config functionality | |
1033 | ||
1034 | - Added Mathieu Lafon's patch which upgrades the status of | |
1035 | the NAT-Traversal implementation to RFC 3947. | |
1036 | ||
1037 | - The _startklips script now also loads the xfrm4_tunnel | |
1038 | module. | |
1039 | ||
1040 | - Added Ulrich Weber's netlink replay window size and | |
1041 | maximum udp size patches. | |
1042 | ||
1043 | - UML testing now uses the Linux 2.6.10 UML kernel by default. | |
1044 | ||
1045 | ||
1046 | strongswan-2.3.0 | |
1047 | ---------------- | |
1048 | ||
1049 | - Eric Marchionni and Patrik Rayo, both recent graduates from | |
1050 | the Zuercher Hochschule Winterthur in Switzerland, created a | |
1051 | User-Mode-Linux test setup for strongSwan. For more details | |
1052 | please read the INSTALL and README documents in the testing | |
1053 | subdirectory. | |
1054 | ||
1055 | - Full support of group attributes based on X.509 attribute | |
1056 | certificates. Attribute certificates can be generated | |
1057 | using the openac facility. For more details see | |
1058 | ||
1059 | man ipsec_openac. | |
1060 | ||
1061 | The group attributes can be used in connection definitions | |
1062 | in order to give IPsec access to specific user groups. | |
1063 | This is done with the new parameter left|rightgroups as in | |
1064 | ||
1065 | rightgroups="Research, Sales" | |
1066 | ||
1067 | giving access to users possessing the group attributes | |
1068 | Research or Sales, only. | |
1069 | ||
1070 | - In Quick Mode clients with subnet mask /32 are now | |
1071 | coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should | |
1072 | fix rekeying problems with the SafeNet/SoftRemote and NCP | |
1073 | Secure Entry Clients. | |
1074 | ||
1075 | - Changed the defaults of the ikelifetime and keylife parameters | |
1076 | to 3h and 1h, respectively. The maximum allowable values are | |
1077 | now both set to 24 h. | |
1078 | ||
1079 | - Suppressed notification wars between two IPsec peers that | |
1080 | could e.g. be triggered by incorrect ISAKMP encryption. | |
1081 | ||
1082 | - Public RSA keys can now have identical IDs if either the | |
1083 | issuing CA or the serial number is different. The serial | |
1084 | number of a certificate is now shown by the command | |
1085 | ||
1086 | ipsec auto --listpubkeys | |
1087 | ||
1088 | ||
1089 | strongswan-2.2.2 | |
1090 | ---------------- | |
1091 | ||
1092 | - Added Tuomo Soini's sourceip feature which allows a strongSwan | |
1093 | roadwarrior to use a fixed Virtual IP (see README section 2.6) | |
1094 | and reduces the well-known four tunnel case on VPN gateways to | |
1095 | a single tunnel definition (see README section 2.4). | |
1096 | ||
1097 | - Fixed a bug occuring with NAT-Traversal enabled when the responder | |
1098 | suddenly turns initiator and the initiator cannot find a matching | |
1099 | connection because of the floated IKE port 4500. | |
1100 | ||
1101 | - Removed misleading ipsec verify command from barf. | |
1102 | ||
1103 | - Running under the native IP stack, ipsec --version now shows | |
1104 | the Linux kernel version (courtesy to the Openswan project). | |
1105 | ||
1106 | ||
1107 | strongswan-2.2.1 | |
1108 | ---------------- | |
1109 | ||
1110 | - Introduced the ipsec auto --listalgs monitoring command which lists | |
1111 | all currently registered IKE and ESP algorithms. | |
1112 | ||
1113 | - Fixed a bug in the ESP algorithm selection occuring when the strict flag | |
1114 | is set and the first proposed transform does not match. | |
1115 | ||
1116 | - Fixed another deadlock in the use of the lock_certs_and_keys() mutex, | |
1117 | occuring when a smartcard is present. | |
1118 | ||
1119 | - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event. | |
1120 | ||
1121 | - Fixed the printing of the notification names (null) | |
1122 | ||
1123 | - Applied another of Herbert Xu's Netlink patches. | |
1124 | ||
1125 | ||
1126 | strongswan-2.2.0 | |
1127 | ---------------- | |
1128 | ||
1129 | - Support of Dead Peer Detection. The connection parameter | |
1130 | ||
1131 | dpdaction=clear|hold | |
1132 | ||
1133 | activates DPD for the given connection. | |
1134 | ||
1135 | - The default Opportunistic Encryption (OE) policy groups are not | |
1136 | automatically included anymore. Those wishing to activate OE can include | |
1137 | the policy group with the following statement in ipsec.conf: | |
1138 | ||
1139 | include /etc/ipsec.d/examples/oe.conf | |
1140 | ||
1141 | The default for [right|left]rsasigkey is now set to %cert. | |
1142 | ||
1143 | - strongSwan now has a Vendor ID of its own which can be activated | |
1144 | using the compile option VENDORID | |
1145 | ||
1146 | - Applied Herbert Xu's patch which sets the compression algorithm correctly. | |
1147 | ||
1148 | - Applied Herbert Xu's patch fixing an ESPINUDP problem | |
1149 | ||
1150 | - Applied Herbert Xu's patch setting source/destination port numbers. | |
1151 | ||
1152 | - Reapplied one of Herbert Xu's NAT-Traversal patches which got | |
1153 | lost during the migration from SuperFreeS/WAN. | |
1154 | ||
1155 | - Fixed a deadlock in the use of the lock_certs_and_keys() mutex. | |
1156 | ||
1157 | - Fixed the unsharing of alg parameters when instantiating group | |
1158 | connection. | |
1159 | ||
1160 | ||
1161 | strongswan-2.1.5 | |
1162 | ---------------- | |
1163 | ||
1164 | - Thomas Walpuski made me aware of a potential DoS attack via | |
1165 | a PKCS#7-wrapped certificate bundle which could overwrite valid CA | |
1166 | certificates in Pluto's authority certificate store. This vulnerability | |
1167 | was fixed by establishing trust in CA candidate certificates up to a | |
1168 | trusted root CA prior to insertion into Pluto's chained list. | |
1169 | ||
1170 | - replaced the --assign option by the -v option in the auto awk script | |
1171 | in order to make it run with mawk under debian/woody. | |
1172 | ||
1173 | ||
1174 | strongswan-2.1.4 | |
1175 | ---------------- | |
1176 | ||
1177 | - Split of the status information between ipsec auto --status (concise) | |
1178 | and ipsec auto --statusall (verbose). Both commands can be used with | |
1179 | an optional connection selector: | |
1180 | ||
1181 | ipsec auto --status[all] <connection_name> | |
1182 | ||
1183 | - Added the description of X.509 related features to the ipsec_auto(8) | |
1184 | man page. | |
1185 | ||
1186 | - Hardened the ASN.1 parser in debug mode, especially the printing | |
1187 | of malformed distinguished names. | |
1188 | ||
1189 | - The size of an RSA public key received in a certificate is now restricted to | |
1190 | ||
1191 | 512 bits <= modulus length <= 8192 bits. | |
1192 | ||
1193 | - Fixed the debug mode enumeration. | |
1194 | ||
1195 | ||
1196 | strongswan-2.1.3 | |
1197 | ---------------- | |
1198 | ||
1199 | - Fixed another PKCS#7 vulnerability which could lead to an | |
1200 | endless loop while following the X.509 trust chain. | |
1201 | ||
1202 | ||
1203 | strongswan-2.1.2 | |
1204 | ---------------- | |
1205 | ||
1206 | - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski | |
1207 | that accepted end certificates having identical issuer and subject | |
1208 | distinguished names in a multi-tier X.509 trust chain. | |
1209 | ||
1210 | ||
1211 | strongswan-2.1.1 | |
1212 | ---------------- | |
1213 | ||
1214 | - Removed all remaining references to ipsec_netlink.h in KLIPS. | |
1215 | ||
1216 | ||
1217 | strongswan-2.1.0 | |
1218 | ---------------- | |
1219 | ||
1220 | - The new "ca" section allows to define the following parameters: | |
1221 | ||
1222 | ca kool | |
1223 | cacert=koolCA.pem # cacert of kool CA | |
1224 | ocspuri=http://ocsp.kool.net:8001 # ocsp server | |
1225 | ldapserver=ldap.kool.net # default ldap server | |
1226 | crluri=http://www.kool.net/kool.crl # crl distribution point | |
1227 | crluri2="ldap:///O=Kool, C= .." # crl distribution point #2 | |
1228 | auto=add # add, ignore | |
1229 | ||
1230 | The ca definitions can be monitored via the command | |
1231 | ||
1232 | ipsec auto --listcainfos | |
1233 | ||
1234 | - Fixed cosmetic corruption of /proc filesystem by integrating | |
1235 | D. Hugh Redelmeier's freeswan-2.06 kernel fixes. | |
1236 | ||
1237 | ||
1238 | strongswan-2.0.2 | |
1239 | ---------------- | |
1240 | ||
1241 | - Added support for the 818043 NAT-Traversal update of Microsoft's | |
1242 | Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode. | |
1243 | ||
1244 | - A symbolic link to libcrypto is now added in the kernel sources | |
1245 | during kernel compilation | |
1246 | ||
1247 | - Fixed a couple of 64 bit issues (mostly casts to int). | |
1248 | Thanks to Ken Bantoft who checked my sources on a 64 bit platform. | |
1249 | ||
1250 | - Replaced s[n]printf() statements in the kernel by ipsec_snprintf(). | |
1251 | Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro | |
1252 | of the FreeS/WAN team who solved this problem with the 2.4.25 kernel. | |
1253 | ||
1254 | ||
1255 | strongswan-2.0.1 | |
1256 | ---------------- | |
1257 | ||
1258 | - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName | |
1259 | certificate extension which contains no generalName item) can cause | |
1260 | a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has | |
1261 | been hardened to make it more robust against malformed ASN.1 objects. | |
1262 | ||
1263 | - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native | |
1264 | Linux 2.6 IPsec stack. | |
1265 | ||
1266 | ||
1267 | strongswan-2.0.0 | |
1268 | ---------------- | |
1269 | ||
1270 | - based on freeswan-2.04, x509-1.5.3, nat-0.6c, alg-0.8.1rc12 |
