1 | strongswan-4.2.3 |
2 | ---------------- | |
3 | ||
4 | - Fixed the strongswan.conf path configuration problem that occurred when | |
5 | --sysconfig was not set explicitly in ./configure. | |
6 | ||
7 | - Fixed a number of minor bugs that where discovered during the 4th | |
8 | IKEv2 interoperability workshop in San Antonio, TX. | |

11 | strongswan-4.2.2 |
12 | ---------------- | |
13 | ||
a57cd446 AS |
14 | - Plugins for libstrongswan and charon can optionally be loaded according |
15 | to a configuration in strongswan.conf. Most components provide a | |
7f491111 | 16 | "load = " option followed by a space separated list of plugins to load. |
a57cd446 AS |
17 | This allows e.g. the fallback from a hardware crypto accelerator to |
18 | to software-based crypto plugins. | |
7f491111 MW |
19 | |
20 | - Charons SQL plugin has been extended by a virtual IP address pool. | |
a57cd446 AS |
21 | Configurations with a rightsourceip=%poolname setting query a SQLite or |
22 | MySQL database for leases. The "ipsec pool" command helps in administrating | |
23 | the pool database. See ipsec pool --help for the available options | |
24 | ||
25 | - The Authenticated Encryption Algorithms AES-CCM-8/12/16 and AES-GCM-8/12/16 | |
26 | for ESP are now supported starting with the Linux 2.6.25 kernel. The | |
27 | syntax is e.g. esp=aes128ccm12 or esp=aes256gcm16. | |
28 | ||

5c5d67d6 AS |
30 | strongswan-4.2.1 |
31 | ---------------- | |
32 | ||
c306dfb1 | 33 | - Support for "Hash and URL" encoded certificate payloads has been implemented |
b1f8fc0c TB |
34 | in the IKEv2 daemon charon. Using the "certuribase" option of a CA section |
35 | allows to assign a base URL to all certificates issued by the specified CA. | |
36 | The final URL is then built by concatenating that base and the hex encoded | |
37 | SHA1 hash of the DER encoded certificate. Note that this feature is disabled | |
38 | by default and must be enabled using the option "charon.hash_and_url". | |
5c5d67d6 | 39 | |
58caabf7 MW |
40 | - The IKEv2 daemon charon now supports the "uniqueids" option to close multiple |
41 | IKE_SAs with the same peer. The option value "keep" prefers existing | |
42 | connection setups over new ones, where the value "replace" replaces existing | |
43 | connections. | |
44 | ||
45 | - The crypto factory in libstrongswan additionaly supports random number | |
46 | generators, plugins may provide other sources of randomness. The default | |
c306dfb1 | 47 | plugin reads raw random data from /dev/(u)random. |
58caabf7 MW |
48 | |
49 | - Extended the credential framework by a caching option to allow plugins | |
50 | persistent caching of fetched credentials. The "cachecrl" option has been | |
c306dfb1 | 51 | re-implemented. |
58caabf7 MW |
52 | |
53 | - The new trustchain verification introduced in 4.2.0 has been parallelized. | |
54 | Threads fetching CRL or OCSP information no longer block other threads. | |
5c5d67d6 | 55 | |
58caabf7 MW |
56 | - A new IKEv2 configuration attribute framework has been introduced allowing |
57 | plugins to provide virtual IP addresses, and in the future, other | |
58 | configuration attribute services (e.g. DNS/WINS servers). | |
5c5d67d6 | 59 | |
466abb49 | 60 | - The stroke plugin has been extended to provide virtual IP addresses from |
58caabf7 MW |
61 | a pool defined in ipsec.conf. The "rightsourceip" parameter now accepts |
62 | address pools in CIDR notation (e.g. 10.1.1.0/24). The parameter also accepts | |
63 | the value "%poolname", where "poolname" identifies a pool provided by a | |
466abb49 | 64 | separate plugin. |
58caabf7 | 65 | |
c306dfb1 | 66 | - Fixed compilation on uClibc and a couple of other minor bugs. |
58caabf7 | 67 | |
c306dfb1 | 68 | - Set DPD defaults in ipsec starter to dpd_delay=30s and dpd_timeout=150s. |
466abb49 AS |
69 | |
70 | - The IKEv1 pluto daemon now supports the ESP encryption algorithm CAMELLIA | |
c306dfb1 | 71 | with key lengths of 128, 192, and 256 bits, as well as the authentication |
466abb49 AS |
72 | algorithm AES_XCBC_MAC. Configuration example: esp=camellia192-aesxcbc. |

75 | strongswan-4.2.0 |
76 | ---------------- | |
77 | ||
16f5dacd MW |
78 | - libstrongswan has been modularized to attach crypto algorithms, |
79 | credential implementations (keys, certificates) and fetchers dynamically | |
80 | through plugins. Existing code has been ported to plugins: | |
81 | - RSA/Diffie-Hellman implementation using the GNU Multi Precision library | |
82 | - X509 certificate system supporting CRLs, OCSP and attribute certificates | |
83 | - Multiple plugins providing crypto algorithms in software | |
84 | - CURL and OpenLDAP fetcher | |
a11ea97d | 85 | |
16f5dacd MW |
86 | - libstrongswan gained a relational database API which uses pluggable database |
87 | providers. Plugins for MySQL and SQLite are available. | |
88 | ||
89 | - The IKEv2 keying daemon charon is more extensible. Generic plugins may provide | |
90 | connection configuration, credentials and EAP methods or control the daemon. | |
91 | Existing code has been ported to plugins: | |
92 | - EAP-AKA, EAP-SIM, EAP-MD5 and EAP-Identity | |
93 | - stroke configuration, credential and control (compatible to pluto) | |
94 | - XML bases management protocol to control and query the daemon | |
95 | The following new plugins are available: | |
96 | - An experimental SQL configuration, credential and logging plugin on | |
97 | top of either MySQL or SQLite | |
98 | - A unit testing plugin to run tests at daemon startup | |
99 | ||
100 | - The authentication and credential framework in charon has been heavily | |
101 | refactored to support modular credential providers, proper | |
102 | CERTREQ/CERT payload exchanges and extensible authorization rules. | |
103 | ||
104 | - The framework of strongSwan Manager has envolved to the web application | |
105 | framework libfast (FastCGI Application Server w/ Templates) and is usable | |
106 | by other applications. | |
107 | ||

109 | strongswan-4.1.11 |
110 | ----------------- | |
fb6d76cd | 111 | |
a561f74d AS |
112 | - IKE rekeying in NAT situations did not inherit the NAT conditions |
113 | to the rekeyed IKE_SA so that the UDP encapsulation was lost with | |
114 | the next CHILD_SA rekeying. | |
115 | ||
116 | - Wrong type definition of the next_payload variable in id_payload.c | |
117 | caused an INVALID_SYNTAX error on PowerPC platforms. | |
fb6d76cd | 118 | |
e6b50b3f AS |
119 | - Implemented IKEv2 EAP-SIM server and client test modules that use |
120 | triplets stored in a file. For details on the configuration see | |
121 | the scenario 'ikev2/rw-eap-sim-rsa'. | |
122 | ||
fb6d76cd | 123 | |
83e0d841 AS |
124 | strongswan-4.1.10 |
125 | ----------------- | |
126 | ||
127 | - Fixed error in the ordering of the certinfo_t records in the ocsp cache that | |
128 | caused multiple entries of the same serial number to be created. | |
129 | ||
fdc7c943 MW |
130 | - Implementation of a simple EAP-MD5 module which provides CHAP |
131 | authentication. This may be interesting in conjunction with certificate | |
132 | based server authentication, as weak passwords can't be brute forced | |
133 | (in contradiction to traditional IKEv2 PSK). | |
134 | ||
135 | - A complete software based implementation of EAP-AKA, using algorithms | |
136 | specified in 3GPP2 (S.S0055). This implementation does not use an USIM, | |
137 | but reads the secrets from ipsec.secrets. Make sure to read eap_aka.h | |
138 | before using it. | |
139 | ||
140 | - Support for vendor specific EAP methods using Expanded EAP types. The | |
141 | interface to EAP modules has been slightly changed, so make sure to | |
142 | check the changes if you're already rolling your own modules. | |
83e0d841 | 143 | |

5076770c AS |
145 | strongswan-4.1.9 |
146 | ---------------- | |
147 | ||
800b3356 AS |
148 | - The default _updown script now dynamically inserts and removes ip6tables |
149 | firewall rules if leftfirewall=yes is set in IPv6 connections. New IPv6 | |
150 | net-net and roadwarrior (PSK/RSA) scenarios for both IKEv1 and IKEV2 were | |
151 | added. | |
5076770c | 152 | |
6f274c2a MW |
153 | - Implemented RFC4478 repeated authentication to force EAP/Virtual-IP clients |
154 | to reestablish an IKE_SA within a given timeframe. | |
155 | ||
156 | - strongSwan Manager supports configuration listing, initiation and termination | |
157 | of IKE and CHILD_SAs. | |
158 | ||
159 | - Fixes and improvements to multithreading code. | |
160 | ||
8b678ad4 MW |
161 | - IKEv2 plugins have been renamed to libcharon-* to avoid naming conflicts. |
162 | Make sure to remove the old plugins in $libexecdir/ipsec, otherwise they get | |
163 | loaded twice. | |
5076770c | 164 | |
83e0d841 | 165 | |
b82e8231 AS |
166 | strongswan-4.1.8 |
167 | ---------------- | |
168 | ||
5076770c | 169 | - Removed recursive pthread mutexes since uClibc doesn't support them. |
b82e8231 AS |
170 | |
171 | ||
a4a3632c AS |
172 | strongswan-4.1.7 |
173 | ---------------- | |
174 | ||
175 | - In NAT traversal situations and multiple queued Quick Modes, | |
176 | those pending connections inserted by auto=start after the | |
177 | port floating from 500 to 4500 were erronously deleted. | |
178 | ||
6e193274 | 179 | - Added a "forceencaps" connection parameter to enforce UDP encapsulation |
078b6008 | 180 | to surmount restrictive firewalls. NAT detection payloads are faked to |
6e193274 MW |
181 | simulate a NAT situation and trick the other peer into NAT mode (IKEv2 only). |
182 | ||
183 | - Preview of strongSwan Manager, a web based configuration and monitoring | |
184 | application. It uses a new XML control interface to query the IKEv2 daemon | |
185 | (see http://trac.strongswan.org/wiki/Manager). | |
186 | ||
187 | - Experimental SQLite configuration backend which will provide the configuration | |
188 | interface for strongSwan Manager in future releases. | |
189 | ||
190 | - Further improvements to MOBIKE support. | |
191 | ||
a4a3632c | 192 | |
3dcf9dbd AS |
193 | strongswan-4.1.6 |
194 | ---------------- | |
195 | ||
3eac4dfd AS |
196 | - Since some third party IKEv2 implementations run into |
197 | problems with strongSwan announcing MOBIKE capability per | |
198 | default, MOBIKE can be disabled on a per-connection-basis | |
199 | using the mobike=no option. Whereas mobike=no disables the | |
200 | sending of the MOBIKE_SUPPORTED notification and the floating | |
201 | to UDP port 4500 with the IKE_AUTH request even if no NAT | |
202 | situation has been detected, strongSwan will still support | |
203 | MOBIKE acting as a responder. | |
204 | ||
205 | - the default ipsec routing table plus its corresponding priority | |
206 | used for inserting source routes has been changed from 100 to 220. | |
207 | It can be configured using the --with-ipsec-routing-table and | |
208 | --with-ipsec-routing-table-prio options. | |
209 | ||
bdc0b55b AS |
210 | - the --enable-integrity-test configure option tests the |
211 | integrity of the libstrongswan crypto code during the charon | |
212 | startup. | |
213 | ||
3eac4dfd AS |
214 | - the --disable-xauth-vid configure option disables the sending |
215 | of the XAUTH vendor ID. This can be used as a workaround when | |
216 | interoperating with some Windows VPN clients that get into | |
217 | trouble upon reception of an XAUTH VID without eXtended | |
218 | AUTHentication having been configured. | |
219 | ||
f872f9d1 AS |
220 | - ipsec stroke now supports the rereadsecrets, rereadaacerts, |
221 | rereadacerts, and listacerts options. | |
3dcf9dbd AS |
222 | |
223 | ||
7ad634a2 AS |
224 | strongswan-4.1.5 |
225 | ---------------- | |
226 | ||
227 | - If a DNS lookup failure occurs when resolving right=%<FQDN> | |
228 | or right=<FQDN> combined with rightallowany=yes then the | |
229 | connection is not updated by ipsec starter thus preventing | |
230 | the disruption of an active IPsec connection. Only if the DNS | |
231 | lookup successfully returns with a changed IP address the | |
232 | corresponding connection definition is updated. | |
233 | ||
8f5b363c MW |
234 | - Routes installed by the keying daemons are now in a separate |
235 | routing table with the ID 100 to avoid conflicts with the main | |
236 | table. Route lookup for IKEv2 traffic is done in userspace to ignore | |
237 | routes installed for IPsec, as IKE traffic shouldn't get encapsulated. | |
238 | ||
7ad634a2 | 239 | |
e93c68ba AS |
240 | strongswan-4.1.4 |
241 | ---------------- | |
242 | ||
243 | - The pluto IKEv1 daemon now exhibits the same behaviour as its | |
244 | IKEv2 companion charon by inserting an explicit route via the | |
245 | _updown script only if a sourceip exists. This is admissible | |
246 | since routing through the IPsec tunnel is handled automatically | |
b7af55ac AS |
247 | by NETKEY's IPsec policies. As a consequence the left|rightnexthop |
248 | parameter is not required any more. | |
078ce348 AS |
249 | |
250 | - The new IKEv1 parameter right|leftallowany parameters helps to handle | |
251 | the case where both peers possess dynamic IP addresses that are | |
252 | usually resolved using DynDNS or a similar service. The configuration | |
253 | ||
254 | right=peer.foo.bar | |
255 | rightallowany=yes | |
256 | ||
257 | can be used by the initiator to start up a connection to a peer | |
258 | by resolving peer.foo.bar into the currently allocated IP address. | |
259 | Thanks to the rightallowany flag the connection behaves later on | |
260 | as | |
261 | ||
262 | right=%any | |
263 | ||
264 | so that the peer can rekey the connection as an initiator when his | |
1fbdab85 AS |
265 | IP address changes. An alternative notation is |
266 | ||
267 | right=%peer.foo.bar | |
268 | ||
269 | which will implicitly set rightallowany=yes. | |
270 | ||
271 | - ipsec starter now fails more gracefully in the presence of parsing | |
272 | errors. Flawed ca and conn section are discarded and pluto is started | |
273 | if non-fatal errors only were encountered. If right=%peer.foo.bar | |
274 | cannot be resolved by DNS then right=%any will be used so that passive | |
275 | connections as a responder are still possible. | |
078ce348 | 276 | |
a0a0bdd7 AS |
277 | - The new pkcs11initargs parameter that can be placed in the |
278 | setup config section of /etc/ipsec.conf allows the definition | |
279 | of an argument string that is used with the PKCS#11 C_Initialize() | |
280 | function. This non-standard feature is required by the NSS softoken | |
281 | library. This patch was contributed by Robert Varga. | |
282 | ||
283 | - Fixed a bug in ipsec starter introduced by strongswan-2.8.5 | |
284 | which caused a segmentation fault in the presence of unknown | |
285 | or misspelt keywords in ipsec.conf. This bug fix was contributed | |
286 | by Robert Varga. | |
287 | ||
e3606f2b MW |
288 | - Partial support for MOBIKE in IKEv2. The initiator acts on interface/ |
289 | address configuration changes and updates IKE and IPsec SAs dynamically. | |
e93c68ba | 290 | |
06651827 | 291 | |
a3354a69 AS |
292 | strongswan-4.1.3 |
293 | ---------------- | |
294 | ||
41e16cf4 | 295 | - IKEv2 peer configuration selection now can be based on a given |
35d4809c AS |
296 | certification authority using the rightca= statement. |
297 | ||
298 | - IKEv2 authentication based on RSA signatures now can handle multiple | |
41e16cf4 AS |
299 | certificates issued for a given peer ID. This allows a smooth transition |
300 | in the case of a peer certificate renewal. | |
a3354a69 | 301 | |
998ca0ea MW |
302 | - IKEv2: Support for requesting a specific virtual IP using leftsourceip on the |
303 | client and returning requested virtual IPs using rightsourceip=%config | |
304 | on the server. If the server does not support configuration payloads, the | |
305 | client enforces its leftsourceip parameter. | |
306 | ||
307 | - The ./configure options --with-uid/--with-gid allow pluto and charon | |
308 | to drop their privileges to a minimum and change to an other UID/GID. This | |
309 | improves the systems security, as a possible intruder may only get the | |
310 | CAP_NET_ADMIN capability. | |
311 | ||
312 | - Further modularization of charon: Pluggable control interface and | |
313 | configuration backend modules provide extensibility. The control interface | |
314 | for stroke is included, and further interfaces using DBUS (NetworkManager) | |
315 | or XML are on the way. A backend for storing configurations in the daemon | |
316 | is provided and more advanced backends (using e.g. a database) are trivial | |
317 | to implement. | |
a3354a69 | 318 | |
41e16cf4 AS |
319 | - Fixed a compilation failure in libfreeswan occuring with Linux kernel |
320 | headers > 2.6.17. | |
321 | ||
322 | ||
8ea7b96f AS |
323 | strongswan-4.1.2 |
324 | ---------------- | |
325 | ||
e23d98a7 | 326 | - Support for an additional Diffie-Hellman exchange when creating/rekeying |
37fb0355 MW |
327 | a CHILD_SA in IKEv2 (PFS). PFS is enabled when the proposal contains a |
328 | DH group (e.g. "esp=aes128-sha1-modp1536"). Further, DH group negotiation | |
329 | is implemented properly for rekeying. | |
330 | ||
331 | - Support for the AES-XCBC-96 MAC algorithm for IPsec SAs when using IKEv2 | |
332 | (requires linux >= 2.6.20). It is enabled using e.g. "esp=aes256-aesxcbc". | |
333 | ||
d931f465 MW |
334 | - Working IPv4-in-IPv6 and IPv6-in-IPv4 tunnels for linux >= 2.6.21. |
335 | ||
37fb0355 MW |
336 | - Added support for EAP modules which do not establish an MSK. |
337 | ||
dfbe2a0f | 338 | - Removed the dependencies from the /usr/include/linux/ headers by |
9f78f957 | 339 | including xfrm.h, ipsec.h, and pfkeyv2.h in the distribution. |
dfbe2a0f | 340 | |
9f78f957 AS |
341 | - crlNumber is now listed by ipsec listcrls |
342 | ||
8ea7b96f AS |
343 | - The xauth_modules.verify_secret() function now passes the |
344 | connection name. | |
345 | ||
e23d98a7 | 346 | |
ed284399 MW |
347 | strongswan-4.1.1 |
348 | ---------------- | |
349 | ||
350 | - Server side cookie support. If to may IKE_SAs are in CONNECTING state, | |
351 | cookies are enabled and protect against DoS attacks with faked source | |
352 | addresses. Number of IKE_SAs in CONNECTING state is also limited per | |
353 | peer address to avoid resource exhaustion. IKE_SA_INIT messages are | |
354 | compared to properly detect retransmissions and incoming retransmits are | |
355 | detected even if the IKE_SA is blocked (e.g. doing OCSP fetches). | |
356 | ||
db88e37d AS |
357 | - The IKEv2 daemon charon now supports dynamic http- and ldap-based CRL |
358 | fetching enabled by crlcheckinterval > 0 and caching fetched CRLs | |
359 | enabled by cachecrls=yes. | |
360 | ||
3b4f7d92 AS |
361 | - Added the configuration options --enable-nat-transport which enables |
362 | the potentially insecure NAT traversal for IPsec transport mode and | |
363 | --disable-vendor-id which disables the sending of the strongSwan | |
364 | vendor ID. | |
365 | ||
366 | - Fixed a long-standing bug in the pluto IKEv1 daemon which caused | |
367 | a segmentation fault if a malformed payload was detected in the | |
368 | IKE MR2 message and pluto tried to send an encrypted notification | |
369 | message. | |
370 | ||
46b9ff68 AS |
371 | - Added the NATT_IETF_02_N Vendor ID in order to support IKEv1 connections |
372 | with Windows 2003 Server which uses a wrong VID hash. | |
373 | ||
3b4f7d92 | 374 | |
34bbd0c3 | 375 | strongswan-4.1.0 |
cd3958f8 AS |
376 | ---------------- |
377 | ||
378 | - Support of SHA2_384 hash function for protecting IKEv1 | |
379 | negotiations and support of SHA2 signatures in X.509 certificates. | |
380 | ||
381 | - Fixed a serious bug in the computation of the SHA2-512 HMAC | |
382 | function. Introduced automatic self-test of all IKEv1 hash | |
383 | and hmac functions during pluto startup. Failure of a self-test | |
384 | currently issues a warning only but does not exit pluto [yet]. | |
385 | ||
9b45443d MW |
386 | - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2. |
387 | ||
c5d0fbb6 AS |
388 | - Full support of CA information sections. ipsec listcainfos |
389 | now shows all collected crlDistributionPoints and OCSP | |
390 | accessLocations. | |
391 | ||
69ed04bf AS |
392 | - Support of the Online Certificate Status Protocol (OCSP) for IKEv2. |
393 | This feature requires the HTTP fetching capabilities of the libcurl | |
394 | library which must be enabled by setting the --enable-http configure | |
395 | option. | |
396 | ||
9b45443d MW |
397 | - Refactored core of the IKEv2 message processing code, allowing better |
398 | code reuse and separation. | |
399 | ||
400 | - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration | |
401 | payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted | |
402 | by the requestor and installed in a resolv.conf file. | |
403 | ||
404 | - The IKEv2 daemon charon installs a route for each IPsec policy to use | |
405 | the correct source address even if an application does not explicitly | |
406 | specify it. | |
407 | ||
408 | - Integrated the EAP framework into charon which loads pluggable EAP library | |
409 | modules. The ipsec.conf parameter authby=eap initiates EAP authentication | |
410 | on the client side, while the "eap" parameter on the server side defines | |
411 | the EAP method to use for client authentication. | |
412 | A generic client side EAP-Identity module and an EAP-SIM authentication | |
413 | module using a third party card reader implementation are included. | |
414 | ||
415 | - Added client side support for cookies. | |
416 | ||
417 | - Integrated the fixes done at the IKEv2 interoperability bakeoff, including | |
418 | strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor | |
419 | fixes to enhance interoperability with other implementations. | |

422 | strongswan-4.0.7 |
423 | ---------------- | |
424 | ||
6fdf5f44 AS |
425 | - strongSwan now interoperates with the NCP Secure Entry Client, |
426 | the Shrew Soft VPN Client, and the Cisco VPN client, doing both | |
427 | XAUTH and Mode Config. | |
1c266d7d AS |
428 | |
429 | - UNITY attributes are now recognized and UNITY_BANNER is set | |
430 | to a default string. | |
431 | ||
432 | ||
2b4405a3 MW |
433 | strongswan-4.0.6 |
434 | ---------------- | |
435 | ||
e38a15d4 AS |
436 | - IKEv1: Support for extended authentication (XAUTH) in combination |
437 | with ISAKMP Main Mode RSA or PSK authentication. Both client and | |
438 | server side were implemented. Handling of user credentials can | |
439 | be done by a run-time loadable XAUTH module. By default user | |
440 | credentials are stored in ipsec.secrets. | |
441 | ||
2b4405a3 MW |
442 | - IKEv2: Support for reauthentication when rekeying |
443 | ||
5903179b | 444 | - IKEv2: Support for transport mode |
af87afed | 445 | |
5903179b | 446 | - fixed a lot of bugs related to byte order |
2b4405a3 | 447 | |
5903179b | 448 | - various other bugfixes |
2b4405a3 MW |
449 | |
450 | ||
0cd645d2 AS |
451 | strongswan-4.0.5 |
452 | ---------------- | |
453 | ||
454 | - IKEv1: Implementation of ModeConfig push mode via the new connection | |
455 | keyword modeconfig=push allows interoperability with Cisco VPN gateways. | |
456 | ||
457 | - IKEv1: The command ipsec statusall now shows "DPD active" for all | |
458 | ISAKMP SAs that are under active Dead Peer Detection control. | |
459 | ||
460 | - IKEv2: Charon's logging and debugging framework has been completely rewritten. | |
461 | Instead of logger, special printf() functions are used to directly | |
462 | print objects like hosts (%H) identifications (%D), certificates (%Q), | |
463 | etc. The number of debugging levels have been reduced to: | |
03bf883d | 464 | |
0cd645d2 | 465 | 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private) |
03bf883d | 466 | |
0cd645d2 AS |
467 | The debugging levels can either be specified statically in ipsec.conf as |
468 | ||
469 | config setup | |
03bf883d | 470 | charondebug="lib 1, cfg 3, net 2" |
0cd645d2 | 471 | |
03bf883d | 472 | or changed at runtime via stroke as |
0cd645d2 | 473 | |
03bf883d | 474 | ipsec stroke loglevel cfg 2 |
0cd645d2 AS |

476 | ||
48dc3934 MW |
477 | strongswan-4.0.4 |
478 | ---------------- | |
479 | ||
480 | - Implemented full support for IPv6-in-IPv6 tunnels. | |
481 | ||
482 | - Added configuration options for dead peer detection in IKEv2. dpd_action | |
483 | types "clear", "hold" and "restart" are supported. The dpd_timeout | |
484 | value is not used, as the normal retransmission policy applies to | |
485 | detect dead peers. The dpd_delay parameter enables sending of empty | |
486 | informational message to detect dead peers in case of inactivity. | |
487 | ||
488 | - Added support for preshared keys in IKEv2. PSK keys configured in | |
489 | ipsec.secrets are loaded. The authby parameter specifies the authentication | |
490 | method to authentificate ourself, the other peer may use PSK or RSA. | |
491 | ||
492 | - Changed retransmission policy to respect the keyingtries parameter. | |
493 | ||
112ad7c3 AS |
494 | - Added private key decryption. PEM keys encrypted with AES-128/192/256 |
495 | or 3DES are supported. | |
48dc3934 MW |
496 | |
497 | - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to | |
498 | encrypt IKE traffic. | |
499 | ||
500 | - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates | |
501 | signed with such a hash algorithm. | |
502 | ||
503 | - Added initial support for updown scripts. The actions up-host/client and | |
504 | down-host/client are executed. The leftfirewall=yes parameter | |
505 | uses the default updown script to insert dynamic firewall rules, a custom | |
506 | updown script may be specified with the leftupdown parameter. | |
507 | ||
508 | ||
a1310b6b MW |
509 | strongswan-4.0.3 |
510 | ---------------- | |
511 | ||
512 | - Added support for the auto=route ipsec.conf parameter and the | |
513 | ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and | |
514 | CHILD_SAs dynamically on demand when traffic is detected by the | |
515 | kernel. | |
516 | ||
517 | - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter. | |
518 | As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only | |
519 | new keys are generated using perfect forward secrecy. An optional flag | |
520 | which enforces reauthentication will be implemented later. | |
521 | ||
b425d998 AS |
522 | - "sha" and "sha1" are now treated as synonyms in the ike= and esp= |
523 | algorithm configuration statements. | |
524 | ||
525 | ||
bf4df11f AS |
526 | strongswan-4.0.2 |
527 | ---------------- | |
528 | ||
623d3dcf AS |
529 | - Full X.509 certificate trust chain verification has been implemented. |
530 | End entity certificates can be exchanged via CERT payloads. The current | |
531 | default is leftsendcert=always, since CERTREQ payloads are not supported | |
532 | yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls. | |
efa40c11 MW |
533 | |
534 | - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2 | |
535 | would offer more possibilities for traffic selection, but the Linux kernel | |
536 | currently does not support it. That's why we stick with these simple | |
537 | ipsec.conf rules for now. | |
538 | ||
623d3dcf AS |
539 | - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no |
540 | IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear, | |
541 | dpddelay=60s). | |
542 | ||
efa40c11 MW |
543 | - Initial NAT traversal support in IKEv2. Charon includes NAT detection |
544 | notify payloads to detect NAT routers between the peers. It switches | |
545 | to port 4500, uses UDP encapsulated ESP packets, handles peer address | |
546 | changes gracefully and sends keep alive message periodically. | |
547 | ||
548 | - Reimplemented IKE_SA state machine for charon, which allows simultaneous | |
549 | rekeying, more shared code, cleaner design, proper retransmission | |
550 | and a more extensible code base. | |
551 | ||
cfd8b27f AS |
552 | - The mixed PSK/RSA roadwarrior detection capability introduced by the |
553 | strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal | |
554 | payloads by the responder right before any defined IKE Main Mode state had | |
555 | been established. Although any form of bad proposal syntax was being correctly | |
556 | detected by the payload parser, the subsequent error handler didn't check | |
557 | the state pointer before logging current state information, causing an | |
558 | immediate crash of the pluto keying daemon due to a NULL pointer. | |
559 | ||
bf4df11f | 560 | |
7e81e975 MW |
561 | strongswan-4.0.1 |
562 | ---------------- | |
563 | ||
c15c3d4b MW |
564 | - Added algorithm selection to charon: New default algorithms for |
565 | ike=aes128-sha-modp2048, as both daemons support it. The default | |
566 | for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles | |
567 | the ike/esp parameter the same way as pluto. As this syntax does | |
568 | not allow specification of a pseudo random function, the same | |
569 | algorithm as for integrity is used (currently sha/md5). Supported | |
570 | algorithms for IKE: | |
571 | Encryption: aes128, aes192, aes256 | |
572 | Integrity/PRF: md5, sha (using hmac) | |
573 | DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192 | |
574 | and for ESP: | |
575 | Encryption: aes128, aes192, aes256, 3des, blowfish128, | |
576 | blowfish192, blowfish256 | |
577 | Integrity: md5, sha1 | |
578 | More IKE encryption algorithms will come after porting libcrypto into | |
579 | libstrongswan. | |
f2c2d395 | 580 | |
c15c3d4b MW |
581 | - initial support for rekeying CHILD_SAs using IKEv2. Currently no |
582 | perfect forward secrecy is used. The rekeying parameters rekey, | |
22ff6f57 | 583 | rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported |
c15c3d4b MW |
584 | when using IKEv2. WARNING: charon currently is unable to handle |
585 | simultaneous rekeying. To avoid such a situation, use a large | |
586 | rekeyfuzz, or even better, set rekey=no on one peer. | |
22ff6f57 | 587 | |
7e81e975 MW |
588 | - support for host2host, net2net, host2net (roadwarrior) tunnels |
589 | using predefined RSA certificates (see uml scenarios for | |
590 | configuration examples). | |
591 | ||
f2c2d395 MW |
592 | - new build environment featuring autotools. Features such |
593 | as HTTP, LDAP and smartcard support may be enabled using | |
594 | the ./configure script. Changing install directories | |
595 | is possible, too. See ./configure --help for more details. | |
596 | ||
22ff6f57 MW |
597 | - better integration of charon with ipsec starter, which allows |
598 | (almost) transparent operation with both daemons. charon | |
599 | handles ipsec commands up, down, status, statusall, listall, | |
600 | listcerts and allows proper load, reload and delete of connections | |
601 | via ipsec starter. | |
602 | ||
b425d998 | 603 | |
9820c0e2 MW |
604 | strongswan-4.0.0 |
605 | ---------------- | |
606 | ||
607 | - initial support of the IKEv2 protocol. Connections in | |
608 | ipsec.conf designated by keyexchange=ikev2 are negotiated | |
609 | by the new IKEv2 charon keying daemon whereas those marked | |
610 | by keyexchange=ikev1 or the default keyexchange=ike are | |
611 | handled thy the IKEv1 pluto keying daemon. Currently only | |
612 | a limited subset of functions are available with IKEv2 | |
613 | (Default AES encryption, authentication based on locally | |
614 | imported X.509 certificates, unencrypted private RSA keys | |
615 | in PKCS#1 file format, limited functionality of the ipsec | |
616 | status command). | |
617 | ||
618 | ||
997358a6 MW |
619 | strongswan-2.7.0 |
620 | ---------------- | |
621 | ||
622 | - the dynamic iptables rules from the _updown_x509 template | |
623 | for KLIPS and the _updown_policy template for NETKEY have | |
624 | been merged into the default _updown script. The existing | |
625 | left|rightfirewall keyword causes the automatic insertion | |
626 | and deletion of ACCEPT rules for tunneled traffic upon | |
627 | the successful setup and teardown of an IPsec SA, respectively. | |
628 | left|rightfirwall can be used with KLIPS under any Linux 2.4 | |
629 | kernel or with NETKEY under a Linux kernel version >= 2.6.16 | |
630 | in conjuction with iptables >= 1.3.5. For NETKEY under a Linux | |
631 | kernel version < 2.6.16 which does not support IPsec policy | |
632 | matching yet, please continue to use a copy of the _updown_espmark | |
633 | template loaded via the left|rightupdown keyword. | |
634 | ||
635 | - a new left|righthostaccess keyword has been introduced which | |
636 | can be used in conjunction with left|rightfirewall and the | |
637 | default _updown script. By default leftfirewall=yes inserts | |
638 | a bi-directional iptables FORWARD rule for a local client network | |
639 | with a netmask different from 255.255.255.255 (single host). | |
640 | This does not allow to access the VPN gateway host via its | |
641 | internal network interface which is part of the client subnet | |
642 | because an iptables INPUT and OUTPUT rule would be required. | |
643 | lefthostaccess=yes will cause this additional ACCEPT rules to | |
644 | be inserted. | |
645 | ||
646 | - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal | |
647 | payload is preparsed in order to find out whether the roadwarrior | |
648 | requests PSK or RSA so that a matching connection candidate can | |
649 | be found. | |
650 | ||
651 | ||
652 | strongswan-2.6.4 | |
653 | ---------------- | |
654 | ||
655 | - the new _updown_policy template allows ipsec policy based | |
656 | iptables firewall rules. Required are iptables version | |
657 | >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes | |
658 | the _updown_espmark template, so that no INPUT mangle rules | |
659 | are required any more. | |
660 | ||
661 | - added support of DPD restart mode | |
662 | ||
663 | - ipsec starter now allows the use of wildcards in include | |
664 | statements as e.g. in "include /etc/my_ipsec/*.conf". | |
665 | Patch courtesy of Matthias Haas. | |
666 | ||
667 | - the Netscape OID 'employeeNumber' is now recognized and can be | |
668 | used as a Relative Distinguished Name in certificates. | |
669 | ||
670 | ||
671 | strongswan-2.6.3 | |
672 | ---------------- | |
673 | ||
674 | - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec | |
675 | command and not of ipsec setup any more. | |
676 | ||
677 | - ipsec starter now supports AH authentication in conjunction with | |
678 | ESP encryption. AH authentication is configured in ipsec.conf | |
679 | via the auth=ah parameter. | |
680 | ||
681 | - The command ipsec scencrypt|scdecrypt <args> is now an alias for | |
682 | ipsec whack --scencrypt|scdecrypt <args>. | |
683 | ||
684 | - get_sa_info() now determines for the native netkey IPsec stack | |
685 | the exact time of the last use of an active eroute. This information | |
686 | is used by the Dead Peer Detection algorithm and is also displayed by | |
687 | the ipsec status command. | |
688 | ||
689 | ||
690 | strongswan-2.6.2 | |
691 | ---------------- | |
692 | ||
693 | - running under the native Linux 2.6 IPsec stack, the function | |
694 | get_sa_info() is called by ipsec auto --status to display the current | |
695 | number of transmitted bytes per IPsec SA. | |
696 | ||
697 | - get_sa_info() is also used by the Dead Peer Detection process to detect | |
698 | recent ESP activity. If ESP traffic was received from the peer within | |
699 | the last dpd_delay interval then no R_Y_THERE notification must be sent. | |
700 | ||
701 | - strongSwan now supports the Relative Distinguished Name "unstructuredName" | |
702 | in ID_DER_ASN1_DN identities. The following notations are possible: | |
703 | ||
704 | rightid="unstructuredName=John Doe" | |
705 | rightid="UN=John Doe" | |
706 | ||
707 | - fixed a long-standing bug which caused PSK-based roadwarrior connections | |
708 | to segfault in the function id.c:same_id() called by keys.c:get_secret() | |
709 | if an FQDN, USER_FQDN, or Key ID was defined, as in the following example. | |
710 | ||
711 | conn rw | |
712 | right=%any | |
713 | rightid=@foo.bar | |
714 | authby=secret | |
715 | ||
716 | - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall). | |
717 | ||
718 | - ipsec starter didn't set host_addr and client.addr ports in whack msg. | |
719 | ||
720 | - in order to guarantee backwards-compatibility with the script-based | |
721 | auto function (e.g. auto --replace), the ipsec starter scripts stores | |
722 | the defaultroute information in the temporary file /var/run/ipsec.info. | |
723 | ||
724 | - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH | |
725 | Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config | |
726 | servers. | |
727 | ||
728 | - the ipsec starter now also recognizes the parameters authby=never and | |
729 | type=passthrough|pass|drop|reject. | |
730 | ||
731 | ||
732 | strongswan-2.6.1 | |
733 | ---------------- | |
734 | ||
735 | - ipsec starter now supports the also parameter which allows | |
736 | a modular structure of the connection definitions. Thus | |
737 | "ipsec start" is now ready to replace "ipsec setup". | |
738 | ||
739 | ||
740 | strongswan-2.6.0 | |
741 | ---------------- | |
742 | ||
743 | - Mathieu Lafon's popular ipsec starter tool has been added to the | |
744 | strongSwan distribution. Many thanks go to Stephan Scholz from astaro | |
745 | for his integration work. ipsec starter is a C program which is going | |
746 | to replace the various shell and awk starter scripts (setup, _plutoload, | |
747 | _plutostart, _realsetup, _startklips, _confread, and auto). Since | |
748 | ipsec.conf is now parsed only once, the starting of multiple tunnels is | |
749 | accelerated tremedously. | |
750 | ||
751 | - Added support of %defaultroute to the ipsec starter. If the IP address | |
752 | changes, a HUP signal to the ipsec starter will automatically | |
753 | reload pluto's connections. | |
754 | ||
755 | - moved most compile time configurations from pluto/Makefile to | |
756 | Makefile.inc by defining the options USE_LIBCURL, USE_LDAP, | |
757 | USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE. | |
758 | ||
759 | - removed the ipsec verify and ipsec newhostkey commands | |
760 | ||
761 | - fixed some 64-bit issues in formatted print statements | |
762 | ||
763 | - The scepclient functionality implementing the Simple Certificate | |
764 | Enrollment Protocol (SCEP) is nearly complete but hasn't been | |
765 | documented yet. | |
766 | ||
767 | ||
768 | strongswan-2.5.7 | |
769 | ---------------- | |
770 | ||
771 | - CA certicates are now automatically loaded from a smartcard | |
772 | or USB crypto token and appear in the ipsec auto --listcacerts | |
773 | listing. | |
774 | ||
775 | ||
776 | strongswan-2.5.6 | |
777 | ---------------- | |
778 | ||
779 | - when using "ipsec whack --scencrypt <data>" with a PKCS#11 | |
780 | library that does not support the C_Encrypt() Cryptoki | |
781 | function (e.g. OpenSC), the RSA encryption is done in | |
782 | software using the public key fetched from the smartcard. | |
783 | ||
784 | - The scepclient function now allows to define the | |
785 | validity of a self-signed certificate using the --days, | |
786 | --startdate, and --enddate options. The default validity | |
787 | has been changed from one year to five years. | |
788 | ||
789 | ||
790 | strongswan-2.5.5 | |
791 | ---------------- | |
792 | ||
793 | - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11 | |
794 | interface to other applications for RSA encryption and decryption | |
795 | via the whack interface. Notation: | |
796 | ||
797 | ipsec whack --scencrypt <data> | |
798 | [--inbase 16|hex|64|base64|256|text|ascii] | |
799 | [--outbase 16|hex|64|base64|256|text|ascii] | |
800 | [--keyid <keyid>] | |
801 | ||
802 | ipsec whack --scdecrypt <data> | |
803 | [--inbase 16|hex|64|base64|256|text|ascii] | |
804 | [--outbase 16|hex|64|base64|256|text|ascii] | |
805 | [--keyid <keyid>] | |
806 | ||
807 | The default setting for inbase and outbase is hex. | |
808 | ||
809 | The new proxy interface can be used for securing symmetric | |
810 | encryption keys required by the cryptoloop or dm-crypt | |
811 | disk encryption schemes, especially in the case when | |
812 | pkcs11keepstate=yes causes pluto to lock the pkcs11 slot | |
813 | permanently. | |
814 | ||
815 | - if the file /etc/ipsec.secrets is lacking during the startup of | |
816 | pluto then the root-readable file /etc/ipsec.d/private/myKey.der | |
817 | containing a 2048 bit RSA private key and a matching self-signed | |
818 | certificate stored in the file /etc/ipsec.d/certs/selfCert.der | |
819 | is automatically generated by calling the function | |
820 | ||
821 | ipsec scepclient --out pkcs1 --out cert-self | |
822 | ||
823 | scepclient was written by Jan Hutter and Martin Willi, students | |
824 | at the University of Applied Sciences in Rapperswil, Switzerland. | |
825 | ||
826 | ||
827 | strongswan-2.5.4 | |
828 | ---------------- | |
829 | ||
830 | - the current extension of the PKCS#7 framework introduced | |
831 | a parsing error in PKCS#7 wrapped X.509 certificates that are | |
832 | e.g. transmitted by Windows XP when multi-level CAs are used. | |
833 | the parsing syntax has been fixed. | |
834 | ||
835 | - added a patch by Gerald Richter which tolerates multiple occurrences | |
836 | of the ipsec0 interface when using KLIPS. | |
837 | ||
838 | ||
839 | strongswan-2.5.3 | |
840 | ---------------- | |
841 | ||
842 | - with gawk-3.1.4 the word "default2 has become a protected | |
843 | keyword for use in switch statements and cannot be used any | |
844 | more in the strongSwan scripts. This problem has been | |
845 | solved by renaming "default" to "defaults" and "setdefault" | |
846 | in the scripts _confread and auto, respectively. | |
847 | ||
848 | - introduced the parameter leftsendcert with the values | |
849 | ||
850 | always|yes (the default, always send a cert) | |
851 | ifasked (send the cert only upon a cert request) | |
852 | never|no (never send a cert, used for raw RSA keys and | |
853 | self-signed certs) | |
854 | ||
855 | - fixed the initialization of the ESP key length to a default of | |
856 | 128 bits in the case that the peer does not send a key length | |
857 | attribute for AES encryption. | |
858 | ||
859 | - applied Herbert Xu's uniqueIDs patch | |
860 | ||
861 | - applied Herbert Xu's CLOEXEC patches | |
862 | ||
863 | ||
864 | strongswan-2.5.2 | |
865 | ---------------- | |
866 | ||
867 | - CRLs can now be cached also in the case when the issuer's | |
868 | certificate does not contain a subjectKeyIdentifier field. | |
869 | In that case the subjectKeyIdentifier is computed by pluto as the | |
870 | 160 bit SHA-1 hash of the issuer's public key in compliance | |
871 | with section 4.2.1.2 of RFC 3280. | |
872 | ||
873 | - Fixed a bug introduced by strongswan-2.5.1 which eliminated | |
874 | not only multiple Quick Modes of a given connection but also | |
875 | multiple connections between two security gateways. | |
876 | ||
877 | ||
878 | strongswan-2.5.1 | |
879 | ---------------- | |
880 | ||
881 | - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute | |
882 | installed either by setting auto=route in ipsec.conf or by | |
883 | a connection put into hold, generates an XFRM_AQUIRE event | |
884 | for each packet that wants to use the not-yet exisiting | |
885 | tunnel. Up to now each XFRM_AQUIRE event led to an entry in | |
886 | the Quick Mode queue, causing multiple IPsec SA to be | |
887 | established in rapid succession. Starting with strongswan-2.5.1 | |
888 | only a single IPsec SA is established per host-pair connection. | |
889 | ||
890 | - Right after loading the PKCS#11 module, all smartcard slots are | |
891 | searched for certificates. The result can be viewed using | |
892 | the command | |
893 | ||
894 | ipsec auto --listcards | |
895 | ||
896 | The certificate objects found in the slots are numbered | |
897 | starting with #1, #2, etc. This position number can be used to address | |
898 | certificates (leftcert=%smartcard) and keys (: PIN %smartcard) | |
899 | in ipsec.conf and ipsec.secrets, respectively: | |
900 | ||
901 | %smartcard (selects object #1) | |
902 | %smartcard#1 (selects object #1) | |
903 | %smartcard#3 (selects object #3) | |
904 | ||
905 | As an alternative the existing retrieval scheme can be used: | |
906 | ||
907 | %smartcard:45 (selects object with id=45) | |
908 | %smartcard0 (selects first object in slot 0) | |
909 | %smartcard4:45 (selects object in slot 4 with id=45) | |
910 | ||
911 | - Depending on the settings of CKA_SIGN and CKA_DECRYPT | |
912 | private key flags either C_Sign() or C_Decrypt() is used | |
913 | to generate a signature. | |
914 | ||
915 | - The output buffer length parameter siglen in C_Sign() | |
916 | is now initialized to the actual size of the output | |
917 | buffer prior to the function call. This fixes the | |
918 | CKR_BUFFER_TOO_SMALL error that could occur when using | |
919 | the OpenSC PKCS#11 module. | |
920 | ||
921 | - Changed the initialization of the PKCS#11 CK_MECHANISM in | |
922 | C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }. | |
923 | ||
924 | - Refactored the RSA public/private key code and transferred it | |
925 | from keys.c to the new pkcs1.c file as a preparatory step | |
926 | towards the release of the SCEP client. | |
927 | ||
928 | ||
929 | strongswan-2.5.0 | |
930 | ---------------- | |
931 | ||
932 | - The loading of a PKCS#11 smartcard library module during | |
933 | runtime does not require OpenSC library functions any more | |
934 | because the corresponding code has been integrated into | |
935 | smartcard.c. Also the RSAREF pkcs11 header files have been | |
936 | included in a newly created pluto/rsaref directory so that | |
937 | no external include path has to be defined any longer. | |
938 | ||
939 | - A long-awaited feature has been implemented at last: | |
940 | The local caching of CRLs fetched via HTTP or LDAP, activated | |
941 | by the parameter cachecrls=yes in the config setup section | |
942 | of ipsec.conf. The dynamically fetched CRLs are stored under | |
943 | a unique file name containing the issuer's subjectKeyID | |
944 | in /etc/ipsec.d/crls. | |
945 | ||
946 | - Applied a one-line patch courtesy of Michael Richardson | |
947 | from the Openswan project which fixes the kernel-oops | |
948 | in KLIPS when an snmp daemon is running on the same box. | |
949 | ||
950 | ||
951 | strongswan-2.4.4 | |
952 | ---------------- | |
953 | ||
954 | - Eliminated null length CRL distribution point strings. | |
955 | ||
956 | - Fixed a trust path evaluation bug introduced with 2.4.3 | |
957 | ||
958 | ||
959 | strongswan-2.4.3 | |
960 | ---------------- | |
961 | ||
962 | - Improved the joint OCSP / CRL revocation policy. | |
963 | OCSP responses have precedence over CRL entries. | |
964 | ||
965 | - Introduced support of CRLv2 reason codes. | |
966 | ||
967 | - Fixed a bug with key-pad equipped readers which caused | |
968 | pluto to prompt for the pin via the console when the first | |
969 | occasion to enter the pin via the key-pad was missed. | |
970 | ||
971 | - When pluto is built with LDAP_V3 enabled, the library | |
972 | liblber required by newer versions of openldap is now | |
973 | included. | |
974 | ||
975 | ||
976 | strongswan-2.4.2 | |
977 | ---------------- | |
978 | ||
979 | - Added the _updown_espmark template which requires all | |
980 | incoming ESP traffic to be marked with a default mark | |
981 | value of 50. | |
982 | ||
983 | - Introduced the pkcs11keepstate parameter in the config setup | |
984 | section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11 | |
985 | session and login states are kept as long as possible during | |
986 | the lifetime of pluto. This means that a PIN entry via a key | |
987 | pad has to be done only once. | |
988 | ||
989 | - Introduced the pkcs11module parameter in the config setup | |
990 | section of ipsec.conf which specifies the PKCS#11 module | |
991 | to be used with smart cards. Example: | |
992 | ||
993 | pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo | |
994 | ||
995 | - Added support of smartcard readers equipped with a PIN pad. | |
996 | ||
997 | - Added patch by Jay Pfeifer which detects when netkey | |
998 | modules have been statically built into the Linux 2.6 kernel. | |
999 | ||
1000 | - Added two patches by Herbert Xu. The first uses ip xfrm | |
1001 | instead of setkey to flush the IPsec policy database. The | |
1002 | second sets the optional flag in inbound IPComp SAs only. | |
1003 | ||
1004 | - Applied Ulrich Weber's patch which fixes an interoperability | |
1005 | problem between native IPsec and KLIPS systems caused by | |
1006 | setting the replay window to 32 instead of 0 for ipcomp. | |
1007 | ||
1008 | ||
1009 | strongswan-2.4.1 | |
1010 | ---------------- | |
1011 | ||
1012 | - Fixed a bug which caused an unwanted Mode Config request | |
1013 | to be initiated in the case where "right" was used to denote | |
1014 | the local side in ipsec.conf and "left" the remote side, | |
1015 | contrary to the recommendation that "right" be remote and | |
1016 | "left" be"local". | |
1017 | ||
1018 | ||
1019 | strongswan-2.4.0a | |
1020 | ----------------- | |
1021 | ||
1022 | - updated Vendor ID to strongSwan-2.4.0 | |
1023 | ||
1024 | - updated copyright statement to include David Buechi and | |
1025 | Michael Meier | |
1026 | ||
1027 | ||
1028 | strongswan-2.4.0 | |
1029 | ---------------- | |
1030 | ||
1031 | - strongSwan now communicates with attached smartcards and | |
1032 | USB crypto tokens via the standardized PKCS #11 interface. | |
1033 | By default the OpenSC library from www.opensc.org is used | |
1034 | but any other PKCS#11 library could be dynamically linked. | |
1035 | strongSwan's PKCS#11 API was implemented by David Buechi | |
1036 | and Michael Meier, both graduates of the Zurich University | |
1037 | of Applied Sciences in Winterthur, Switzerland. | |
1038 | ||
1039 | - When a %trap eroute is triggered by an outgoing IP packet | |
1040 | then the native IPsec stack of the Linux 2.6 kernel [often/ | |
1041 | always?] returns an XFRM_ACQUIRE message with an undefined | |
1042 | protocol family field and the connection setup fails. | |
1043 | As a workaround IPv4 (AF_INET) is now assumed. | |
1044 | ||
1045 | - the results of the UML test scenarios are now enhanced | |
1046 | with block diagrams of the virtual network topology used | |
1047 | in a particular test. | |
1048 | ||
1049 | ||
1050 | strongswan-2.3.2 | |
1051 | ---------------- | |
1052 | ||
1053 | - fixed IV used to decrypt informational messages. | |
1054 | This bug was introduced with Mode Config functionality. | |
1055 | ||
1056 | - fixed NCP Vendor ID. | |
1057 | ||
1058 | - undid one of Ulrich Weber's maximum udp size patches | |
1059 | because it caused a segmentation fault with NAT-ed | |
1060 | Delete SA messages. | |
1061 | ||
1062 | - added UML scenarios wildcards and attr-cert which | |
1063 | demonstrate the implementation of IPsec policies based | |
1064 | on wildcard parameters contained in Distinguished Names and | |
1065 | on X.509 attribute certificates, respectively. | |
1066 | ||
1067 | ||
1068 | strongswan-2.3.1 | |
1069 | ---------------- | |
1070 | ||
1071 | - Added basic Mode Config functionality | |
1072 | ||
1073 | - Added Mathieu Lafon's patch which upgrades the status of | |
1074 | the NAT-Traversal implementation to RFC 3947. | |
1075 | ||
1076 | - The _startklips script now also loads the xfrm4_tunnel | |
1077 | module. | |
1078 | ||
1079 | - Added Ulrich Weber's netlink replay window size and | |
1080 | maximum udp size patches. | |
1081 | ||
1082 | - UML testing now uses the Linux 2.6.10 UML kernel by default. | |
1083 | ||
1084 | ||
1085 | strongswan-2.3.0 | |
1086 | ---------------- | |
1087 | ||
1088 | - Eric Marchionni and Patrik Rayo, both recent graduates from | |
1089 | the Zuercher Hochschule Winterthur in Switzerland, created a | |
1090 | User-Mode-Linux test setup for strongSwan. For more details | |
1091 | please read the INSTALL and README documents in the testing | |
1092 | subdirectory. | |
1093 | ||
1094 | - Full support of group attributes based on X.509 attribute | |
1095 | certificates. Attribute certificates can be generated | |
1096 | using the openac facility. For more details see | |
1097 | ||
1098 | man ipsec_openac. | |
1099 | ||
1100 | The group attributes can be used in connection definitions | |
1101 | in order to give IPsec access to specific user groups. | |
1102 | This is done with the new parameter left|rightgroups as in | |
1103 | ||
1104 | rightgroups="Research, Sales" | |
1105 | ||
1106 | giving access to users possessing the group attributes | |
1107 | Research or Sales, only. | |
1108 | ||
1109 | - In Quick Mode clients with subnet mask /32 are now | |
1110 | coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should | |
1111 | fix rekeying problems with the SafeNet/SoftRemote and NCP | |
1112 | Secure Entry Clients. | |
1113 | ||
1114 | - Changed the defaults of the ikelifetime and keylife parameters | |
1115 | to 3h and 1h, respectively. The maximum allowable values are | |
1116 | now both set to 24 h. | |
1117 | ||
1118 | - Suppressed notification wars between two IPsec peers that | |
1119 | could e.g. be triggered by incorrect ISAKMP encryption. | |
1120 | ||
1121 | - Public RSA keys can now have identical IDs if either the | |
1122 | issuing CA or the serial number is different. The serial | |
1123 | number of a certificate is now shown by the command | |
1124 | ||
1125 | ipsec auto --listpubkeys | |
1126 | ||
1127 | ||
1128 | strongswan-2.2.2 | |
1129 | ---------------- | |
1130 | ||
1131 | - Added Tuomo Soini's sourceip feature which allows a strongSwan | |
1132 | roadwarrior to use a fixed Virtual IP (see README section 2.6) | |
1133 | and reduces the well-known four tunnel case on VPN gateways to | |
1134 | a single tunnel definition (see README section 2.4). | |
1135 | ||
1136 | - Fixed a bug occuring with NAT-Traversal enabled when the responder | |
1137 | suddenly turns initiator and the initiator cannot find a matching | |
1138 | connection because of the floated IKE port 4500. | |
1139 | ||
1140 | - Removed misleading ipsec verify command from barf. | |
1141 | ||
1142 | - Running under the native IP stack, ipsec --version now shows | |
1143 | the Linux kernel version (courtesy to the Openswan project). | |
1144 | ||
1145 | ||
1146 | strongswan-2.2.1 | |
1147 | ---------------- | |
1148 | ||
1149 | - Introduced the ipsec auto --listalgs monitoring command which lists | |
1150 | all currently registered IKE and ESP algorithms. | |
1151 | ||
1152 | - Fixed a bug in the ESP algorithm selection occuring when the strict flag | |
1153 | is set and the first proposed transform does not match. | |
1154 | ||
1155 | - Fixed another deadlock in the use of the lock_certs_and_keys() mutex, | |
1156 | occuring when a smartcard is present. | |
1157 | ||
1158 | - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event. | |
1159 | ||
1160 | - Fixed the printing of the notification names (null) | |
1161 | ||
1162 | - Applied another of Herbert Xu's Netlink patches. | |
1163 | ||
1164 | ||
1165 | strongswan-2.2.0 | |
1166 | ---------------- | |
1167 | ||
1168 | - Support of Dead Peer Detection. The connection parameter | |
1169 | ||
1170 | dpdaction=clear|hold | |
1171 | ||
1172 | activates DPD for the given connection. | |
1173 | ||
1174 | - The default Opportunistic Encryption (OE) policy groups are not | |
1175 | automatically included anymore. Those wishing to activate OE can include | |
1176 | the policy group with the following statement in ipsec.conf: | |
1177 | ||
1178 | include /etc/ipsec.d/examples/oe.conf | |
1179 | ||
1180 | The default for [right|left]rsasigkey is now set to %cert. | |
1181 | ||
1182 | - strongSwan now has a Vendor ID of its own which can be activated | |
1183 | using the compile option VENDORID | |
1184 | ||
1185 | - Applied Herbert Xu's patch which sets the compression algorithm correctly. | |
1186 | ||
1187 | - Applied Herbert Xu's patch fixing an ESPINUDP problem | |
1188 | ||
1189 | - Applied Herbert Xu's patch setting source/destination port numbers. | |
1190 | ||
1191 | - Reapplied one of Herbert Xu's NAT-Traversal patches which got | |
1192 | lost during the migration from SuperFreeS/WAN. | |
1193 | ||
1194 | - Fixed a deadlock in the use of the lock_certs_and_keys() mutex. | |
1195 | ||
1196 | - Fixed the unsharing of alg parameters when instantiating group | |
1197 | connection. | |
1198 | ||
1199 | ||
1200 | strongswan-2.1.5 | |
1201 | ---------------- | |
1202 | ||
1203 | - Thomas Walpuski made me aware of a potential DoS attack via | |
1204 | a PKCS#7-wrapped certificate bundle which could overwrite valid CA | |
1205 | certificates in Pluto's authority certificate store. This vulnerability | |
1206 | was fixed by establishing trust in CA candidate certificates up to a | |
1207 | trusted root CA prior to insertion into Pluto's chained list. | |
1208 | ||
1209 | - replaced the --assign option by the -v option in the auto awk script | |
1210 | in order to make it run with mawk under debian/woody. | |
1211 | ||
1212 | ||
1213 | strongswan-2.1.4 | |
1214 | ---------------- | |
1215 | ||
1216 | - Split of the status information between ipsec auto --status (concise) | |
1217 | and ipsec auto --statusall (verbose). Both commands can be used with | |
1218 | an optional connection selector: | |
1219 | ||
1220 | ipsec auto --status[all] <connection_name> | |
1221 | ||
1222 | - Added the description of X.509 related features to the ipsec_auto(8) | |
1223 | man page. | |
1224 | ||
1225 | - Hardened the ASN.1 parser in debug mode, especially the printing | |
1226 | of malformed distinguished names. | |
1227 | ||
1228 | - The size of an RSA public key received in a certificate is now restricted to | |
1229 | ||
1230 | 512 bits <= modulus length <= 8192 bits. | |
1231 | ||
1232 | - Fixed the debug mode enumeration. | |
1233 | ||
1234 | ||
1235 | strongswan-2.1.3 | |
1236 | ---------------- | |
1237 | ||
1238 | - Fixed another PKCS#7 vulnerability which could lead to an | |
1239 | endless loop while following the X.509 trust chain. | |
1240 | ||
1241 | ||
1242 | strongswan-2.1.2 | |
1243 | ---------------- | |
1244 | ||
1245 | - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski | |
1246 | that accepted end certificates having identical issuer and subject | |
1247 | distinguished names in a multi-tier X.509 trust chain. | |
1248 | ||
1249 | ||
1250 | strongswan-2.1.1 | |
1251 | ---------------- | |
1252 | ||
1253 | - Removed all remaining references to ipsec_netlink.h in KLIPS. | |
1254 | ||
1255 | ||
1256 | strongswan-2.1.0 | |
1257 | ---------------- | |
1258 | ||
1259 | - The new "ca" section allows to define the following parameters: | |
1260 | ||
1261 | ca kool | |
1262 | cacert=koolCA.pem # cacert of kool CA | |
1263 | ocspuri=http://ocsp.kool.net:8001 # ocsp server | |
1264 | ldapserver=ldap.kool.net # default ldap server | |
1265 | crluri=http://www.kool.net/kool.crl # crl distribution point | |
1266 | crluri2="ldap:///O=Kool, C= .." # crl distribution point #2 | |
1267 | auto=add # add, ignore | |
1268 | ||
1269 | The ca definitions can be monitored via the command | |
1270 | ||
1271 | ipsec auto --listcainfos | |
1272 | ||
1273 | - Fixed cosmetic corruption of /proc filesystem by integrating | |
1274 | D. Hugh Redelmeier's freeswan-2.06 kernel fixes. | |
1275 | ||
1276 | ||
1277 | strongswan-2.0.2 | |
1278 | ---------------- | |
1279 | ||
1280 | - Added support for the 818043 NAT-Traversal update of Microsoft's | |
1281 | Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode. | |
1282 | ||
1283 | - A symbolic link to libcrypto is now added in the kernel sources | |
1284 | during kernel compilation | |
1285 | ||
1286 | - Fixed a couple of 64 bit issues (mostly casts to int). | |
1287 | Thanks to Ken Bantoft who checked my sources on a 64 bit platform. | |
1288 | ||
1289 | - Replaced s[n]printf() statements in the kernel by ipsec_snprintf(). | |
1290 | Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro | |
1291 | of the FreeS/WAN team who solved this problem with the 2.4.25 kernel. | |
1292 | ||
1293 | ||
1294 | strongswan-2.0.1 | |
1295 | ---------------- | |
1296 | ||
1297 | - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName | |
1298 | certificate extension which contains no generalName item) can cause | |
1299 | a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has | |
1300 | been hardened to make it more robust against malformed ASN.1 objects. | |
1301 | ||
1302 | - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native | |
1303 | Linux 2.6 IPsec stack. | |
1304 | ||
1305 | ||
1306 | strongswan-2.0.0 | |
1307 | ---------------- | |
1308 | ||
1309 | - based on freeswan-2.04, x509-1.5.3, nat-0.6c, alg-0.8.1rc12 |
