1 | strongswan-5.0.3 |
2 | ---------------- | |
3 | ||
4 | - The new ipseckey plugin enables authentication based on trustworthy public | |
5 | keys stored as IPSECKEY resource records in the DNS and protected by DNSSEC. | |
6 | To do so it uses a DNSSEC enabled resolver, like the one provided by the new | |
7 | unbound plugin, which is based on libldns and libunbound. Both plugins were | |
8 | created by Reto Guadagnini. | |
9 | ||
1fc609fe AS |
10 | - Implemented the TCG TNC IF-IMV 1.4 draft making access requestor identities |
11 | available to an IMV. The OS IMV stores the AR identity together with the | |
12 | device ID in the attest database. | |
13 | ||
14 | - The openssl plugin now uses the AES-NI accelerated version of AES-GCM | |
15 | if the hardware supports it. | |
7a93844f AS |
16 | |
17 | ||
c2a5e7bc AS |
18 | strongswan-5.0.2 |
19 | ---------------- | |
20 | ||
21 | - Implemented all IETF Standard PA-TNC attributes and an OS IMC/IMV | |
22 | pair using them to transfer operating system information. | |
23 | ||
a19d5913 MW |
24 | - The new "ipsec listcounters" command prints a list of global counter values |
25 | about received and sent IKE messages and rekeyings. | |
26 | ||
343e9989 MW |
27 | - A new lookip plugin can perform fast lookup of tunnel information using a |
28 | clients virtual IP and can send notifications about established or deleted | |
29 | tunnels. The "ipsec lookip" command can be used to query such information | |
30 | or receive notifications. | |
31 | ||
ecdd5aed MW |
32 | - The new error-notify plugin catches some common error conditions and allows |
33 | an external application to receive notifications for them over a UNIX socket. | |
34 | ||
6910e5c7 MW |
35 | - IKE proposals can now use a PRF algorithm different to that defined for |
36 | integrity protection. If an algorithm with a "prf" prefix is defined | |
37 | explicitly (such as prfsha1 or prfsha256), no implicit PRF algorithm based on | |
38 | the integrity algorithm is added to the proposal. | |
c2a5e7bc | 39 | |
8fc7bbc6 MW |
40 | - The pkcs11 plugin can now load leftcert certificates from a smartcard for a |
41 | specific ipsec.conf conn section and cacert CA certificates for a specific ca | |
42 | section. | |
43 | ||
78b2a2b1 MW |
44 | - The load-tester plugin gained additional options for certificate generation |
45 | and can load keys and multiple CA certificates from external files. It can | |
46 | install a dedicated outer IP address for each tunnel and tunnel initiation | |
47 | batches can be triggered and monitored externally using the | |
48 | "ipsec load-tester" tool. | |
49 | ||
cc0cc3b5 MW |
50 | - PKCS#7 container parsing has been modularized, and the openssl plugin |
51 | gained an alternative implementation to decrypt and verify such files. | |
52 | In contrast to our own DER parser, OpenSSL can handle BER files, which is | |
53 | required for interoperability of our scepclient with EJBCA. | |
54 | ||
f31b4180 TB |
55 | - Support for the proprietary IKEv1 fragmentation extension has been added. |
56 | Fragments are always handled on receipt but only sent if supported by the peer | |
57 | and if enabled with the new fragmentation ipsec.conf option. | |
58 | ||
0e0870ae MW |
59 | - IKEv1 in charon can now parse certificates received in PKCS#7 containers and |
60 | supports NAT traversal as used by Windows clients. Patches courtesy of | |
61 | Volker RĂ¼melin. | |
62 | ||
2f0441a3 MW |
63 | - The new rdrand plugin provides a high quality / high performance random |
64 | source using the Intel rdrand instruction found on Ivy Bridge processors. | |
65 | ||
73791223 TB |
66 | - The integration test environment was updated and now uses KVM and reproducible |
67 | guest images based on Debian. | |
68 | ||

ecfd714c AS |
70 | strongswan-5.0.1 |
71 | ---------------- | |
72 | ||
6f93927b AS |
73 | - Introduced the sending of the standard IETF Assessment Result |
74 | PA-TNC attribute by all strongSwan Integrity Measurement Verifiers. | |
75 | ||
ecfd714c AS |
76 | - Extended PTS Attestation IMC/IMV pair to provide full evidence of |
77 | the Linux IMA measurement process. All pertinent file information | |
6f93927b | 78 | of a Linux OS can be collected and stored in an SQL database. |
ecfd714c AS |
79 | |
80 | - The PA-TNC and PB-TNC protocols can now process huge data payloads | |
81 | >64 kB by distributing PA-TNC attributes over multiple PA-TNC messages | |
82 | and these messages over several PB-TNC batches. As long as no | |
6f93927b | 83 | consolidated recommandation from all IMVs can be obtained, the TNC |
ecfd714c AS |
84 | server requests more client data by sending an empty SDATA batch. |
85 | ||
804d702b MW |
86 | - The rightgroups2 ipsec.conf option can require group membership during |
87 | a second authentication round, for example during XAuth authentication | |
88 | against a RADIUS server. | |
89 | ||
3423b3a8 MW |
90 | - The xauth-pam backend can authenticate IKEv1 XAuth and Hybrid authenticated |
91 | clients against any PAM service. The IKEv2 eap-gtc plugin does not use | |
92 | PAM directly anymore, but can use any XAuth backend to verify credentials, | |
93 | including xauth-pam. | |
94 | ||
cc48f360 MW |
95 | - The new unity plugin brings support for some parts of the IKEv1 Cisco Unity |
96 | Extension. As client, charon narrows traffic selectors to the received | |
97 | Split-Include attributes and automatically installs IPsec bypass policies | |
98 | for received Local-LAN attributes. As server, charon sends Split-Include | |
99 | attributes for leftsubnet definitions containing multiple subnets to Unity- | |
100 | aware clients. | |
101 | ||
cbe244a5 TB |
102 | - An EAP-Nak payload is returned by clients if the gateway requests an EAP |
103 | method that the client does not support. Clients can also request a specific | |
104 | EAP method by configuring that method with leftauth. | |
105 | ||
106 | - The eap-dynamic plugin handles EAP-Nak payloads returned by clients and uses | |
107 | these to select a different EAP method supported/requested by the client. | |
108 | The plugin initially requests the first registered method or the first method | |
109 | configured with charon.plugins.eap-dynamic.preferred. | |
110 | ||
e76f3d0d MW |
111 | - The new left/rightdns options specify connection specific DNS servers to |
112 | request/respond in IKEv2 configuration payloads or IKEv2 mode config. leftdns | |
113 | can be any (comma separated) combination of %config4 and %config6 to request | |
114 | multiple servers, both for IPv4 and IPv6. rightdns takes a list of DNS server | |
115 | IP addresses to return. | |
116 | ||
69e056a2 MW |
117 | - The left/rightsourceip options now accept multiple addresses or pools. |
118 | leftsourceip can be any (comma separated) combination of %config4, %config6 | |
119 | or fixed IP addresses to request. rightsourceip accepts multiple explicitly | |
120 | specified or referenced named pools. | |
121 | ||
122 | - Multiple connections can now share a single address pool when they use the | |
123 | same definition in one of the rightsourceip pools. | |
124 | ||
4a025539 TB |
125 | - The options charon.interfaces_ignore and charon.interfaces_use allow one to |
126 | configure the network interfaces used by the daemon. | |
127 | ||
128 | - The kernel-netlink plugin supports the charon.install_virtual_ip_on option, | |
129 | which specifies the interface on which virtual IP addresses will be installed. | |
130 | If it is not specified the current behavior of using the outbound interface | |
131 | is preserved. | |
132 | ||
133 | - The kernel-netlink plugin tries to keep the current source address when | |
134 | looking for valid routes to reach other hosts. | |
135 | ||
804d702b MW |
136 | - The autotools build has been migrated to use a config.h header. strongSwan |
137 | development headers will get installed during "make install" if | |
138 | --with-dev-headers has been passed to ./configure. | |
139 | ||
140 | - All crypto primitives gained return values for most operations, allowing | |
141 | crypto backends to fail, for example when using hardware accelerators. | |
ecfd714c | 142 | |

144 | strongswan-5.0.0 |
145 | ---------------- | |
146 | ||
794cdbc5 MW |
147 | - The charon IKE daemon gained experimental support for the IKEv1 protocol. |
148 | Pluto has been removed from the 5.x series, and unless strongSwan is | |
149 | configured with --disable-ikev1 or --disable-ikev2, charon handles both | |
150 | keying protocols. The feature-set of IKEv1 in charon is almost on par with | |
151 | pluto, but currently does not support AH or bundled AH+ESP SAs. Beside | |
152 | RSA/ECDSA, PSK and XAuth, charon also supports the Hybrid authentication | |
153 | mode. Informations for interoperability and migration is available at | |
154 | http://wiki.strongswan.org/projects/strongswan/wiki/CharonPlutoIKEv1. | |
155 | ||
d55c2404 TB |
156 | - Charon's bus_t has been refactored so that loggers and other listeners are |
157 | now handled separately. The single lock was previously cause for deadlocks | |
158 | if extensive listeners, such as the one provided by the updown plugin, wanted | |
159 | to acquire locks that were held by other threads which in turn tried to log | |
160 | messages, and thus were waiting to acquire the same lock currently held by | |
161 | the thread calling the listener. | |
162 | The implemented changes also allow the use of a read/write-lock for the | |
163 | loggers which increases performance if multiple loggers are registered. | |
164 | Besides several interface changes this last bit also changes the semantics | |
165 | for loggers as these may now be called by multiple threads at the same time. | |
166 | ||
ed7186cb TB |
167 | - Source routes are reinstalled if interfaces are reactivated or IP addresses |
168 | reappear. | |
169 | ||
f97c269e TB |
170 | - The thread pool (processor_t) now has more control over the lifecycle of |
171 | a job (see job.h for details). In particular, it now controls the destruction | |
172 | of jobs after execution and the cancellation of jobs during shutdown. Due to | |
173 | these changes the requeueing feature, previously available to callback_job_t | |
174 | only, is now available to all jobs (in addition to a new rescheduling | |
175 | feature). | |
176 | ||
5a6e5e0d MW |
177 | - In addition to trustchain key strength definitions for different public key |
178 | systems, the rightauth option now takes a list of signature hash algorithms | |
179 | considered save for trustchain validation. For example, the setting | |
180 | rightauth=rsa-2048-ecdsa-256-sha256-sha384-sha512 requires a trustchain | |
181 | that uses at least RSA-2048 or ECDSA-256 keys and certificate signatures | |
182 | using SHA-256 or better. | |
183 | ||

93d9a02e TB |
185 | strongswan-4.6.4 |
186 | ---------------- | |
187 | ||
188 | - Fixed a security vulnerability in the gmp plugin. If this plugin was used | |
189 | for RSA signature verification an empty or zeroed signature was handled as | |
190 | a legitimate one. | |
191 | ||
192 | - Fixed several issues with reauthentication and address updates. | |
193 | ||
194 | ||
c224f765 AS |
195 | strongswan-4.6.3 |
196 | ---------------- | |
197 | ||
198 | - The tnc-pdp plugin implements a RADIUS server interface allowing | |
199 | a strongSwan TNC server to act as a Policy Decision Point. | |
200 | ||
4bc7577d MW |
201 | - The eap-radius authentication backend enforces Session-Timeout attributes |
202 | using RFC4478 repeated authentication and acts upon RADIUS Dynamic | |
203 | Authorization extensions, RFC 5176. Currently supported are disconnect | |
204 | requests and CoA messages containing a Session-Timeout. | |
205 | ||
206 | - The eap-radius plugin can forward arbitrary RADIUS attributes from and to | |
207 | clients using custom IKEv2 notify payloads. The new radattr plugin reads | |
208 | attributes to include from files and prints received attributes to the | |
209 | console. | |
c224f765 AS |
210 | |
211 | - Added support for untruncated MD5 and SHA1 HMACs in ESP as used in | |
212 | RFC 4595. | |
213 | ||
d7590217 TB |
214 | - The cmac plugin implements the AES-CMAC-96 and AES-CMAC-PRF-128 algorithms |
215 | as defined in RFC 4494 and RFC 4615, respectively. | |
216 | ||
4e2e77d5 | 217 | - The resolve plugin automatically installs nameservers via resolvconf(8), |
a281494a | 218 | if it is installed, instead of modifying /etc/resolv.conf directly. |
c224f765 | 219 | |
5f1931ad AS |
220 | - The IKEv2 charon daemon supports now raw RSA public keys in RFC 3110 |
221 | DNSKEY and PKCS#1 file format. | |
222 | ||
223 | ||
60e99b37 AS |
224 | strongswan-4.6.2 |
225 | ---------------- | |
226 | ||
227 | - Upgraded the TCG IF-IMC and IF-IMV C API to the upcoming version 1.3 | |
228 | which supports IF-TNCCS 2.0 long message types, the exclusive flags | |
229 | and multiple IMC/IMV IDs. Both the TNC Client and Server as well as | |
230 | the "Test", "Scanner", and "Attestation" IMC/IMV pairs were updated. | |
231 | ||
232 | - Fully implemented the "TCG Attestation PTS Protocol: Binding to IF-M" | |
233 | standard (TLV-based messages only). TPM-based remote attestation of | |
de4a0c83 AS |
234 | Linux IMA (Integrity Measurement Architecture) possible. Measurement |
235 | reference values are automatically stored in an SQLite database. | |
60e99b37 | 236 | |
a345aa26 MW |
237 | - The EAP-RADIUS authentication backend supports RADIUS accounting. It sends |
238 | start/stop messages containing Username, Framed-IP and Input/Output-Octets | |
239 | attributes and has been tested against FreeRADIUS and Microsoft NPS. | |
60e99b37 | 240 | |
de4a0c83 AS |
241 | - Added support for PKCS#8 encoded private keys via the libstrongswan |
242 | pkcs8 plugin. This is the default format used by some OpenSSL tools since | |
243 | version 1.0.0 (e.g. openssl req with -keyout). | |
dcefa267 | 244 | |
a8958012 MW |
245 | - Added session resumption support to the strongSwan TLS stack. |
246 | ||
de4a0c83 | 247 | |
acb92cb4 AS |
248 | strongswan-4.6.1 |
249 | ---------------- | |
250 | ||
251 | - Because of changing checksums before and after installation which caused | |
252 | the integrity tests to fail we avoided directly linking libsimaka, libtls and | |
253 | libtnccs to those libcharon plugins which make use of these dynamic libraries. | |
18f85b66 AS |
254 | Instead we linked the libraries to the charon daemon. Unfortunately Ubuntu |
255 | 11.10 activated the --as-needed ld option which discards explicit links | |
256 | to dynamic libraries that are not actually used by the charon daemon itself, | |
257 | thus causing failures during the loading of the plugins which depend on these | |
258 | libraries for resolving external symbols. | |
acb92cb4 AS |
259 | |
260 | - Therefore our approach of computing integrity checksums for plugins had to be | |
261 | changed radically by moving the hash generation from the compilation to the | |
262 | post-installation phase. | |

92a1b234 | 265 | strongswan-4.6.0 |
5a2e2e0b AS |
266 | ---------------- |
267 | ||
37276728 MW |
268 | - The new libstrongswan certexpire plugin collects expiration information of |
269 | all used certificates and exports them to CSV files. It either directly | |
270 | exports them or uses cron style scheduling for batch exports. | |
271 | ||
272 | - starter passes unresolved hostnames to charon, allowing it to do name | |
273 | resolution not before the connection attempt. This is especially useful with | |
274 | connections between hosts using dynamic IP addresses. Thanks to Mirko Parthey | |
275 | for the initial patch. | |
276 | ||
5fd8e530 TB |
277 | - The android plugin can now be used without the Android frontend patch and |
278 | provides DNS server registration and logging to logcat. | |
279 | ||
280 | - Pluto and starter (plus stroke and whack) have been ported to Android. | |
281 | ||
602ee58e TB |
282 | - Support for ECDSA private and public key operations has been added to the |
283 | pkcs11 plugin. The plugin now also provides DH and ECDH via PKCS#11 and can | |
284 | use tokens as random number generators (RNG). By default only private key | |
285 | operations are enabled, more advanced features have to be enabled by their | |
286 | option in strongswan.conf. This also applies to public key operations (even | |
287 | for keys not stored on the token) which were enabled by default before. | |
288 | ||
37276728 MW |
289 | - The libstrongswan plugin system now supports detailed plugin dependencies. |
290 | Many plugins have been extended to export its capabilities and requirements. | |
291 | This allows the plugin loader to resolve plugin loading order automatically, | |
292 | and in future releases, to dynamically load the required features on demand. | |
293 | Existing third party plugins are source (but not binary) compatible if they | |
294 | properly initialize the new get_features() plugin function to NULL. | |
295 | ||
fd81ac05 AS |
296 | - The tnc-ifmap plugin implements a TNC IF-MAP 2.0 client which can deliver |
297 | metadata about IKE_SAs via a SOAP interface to a MAP server. The tnc-ifmap | |
298 | plugin requires the Apache Axis2/C library. | |
299 | ||
37276728 | 300 | |
5d179d19 AS |
301 | strongswan-4.5.3 |
302 | ---------------- | |
303 | ||
a7edbd21 | 304 | - Our private libraries (e.g. libstrongswan) are not installed directly in |
b18a697a AS |
305 | prefix/lib anymore. Instead a subdirectory is used (prefix/lib/ipsec/ by |
306 | default). The plugins directory is also moved from libexec/ipsec/ to that | |
a7edbd21 TB |
307 | directory. |
308 | ||
b18a697a AS |
309 | - The dynamic IMC/IMV libraries were moved from the plugins directory to |
310 | a new imcvs directory in the prefix/lib/ipsec/ subdirectory. | |
311 | ||
107ea60f TB |
312 | - Job priorities were introduced to prevent thread starvation caused by too |
313 | many threads handling blocking operations (such as CRL fetching). Refer to | |
314 | strongswan.conf(5) for details. | |
315 | ||
316 | - Two new strongswan.conf options allow to fine-tune performance on IKEv2 | |
317 | gateways by dropping IKE_SA_INIT requests on high load. | |
318 | ||
f8799170 | 319 | - IKEv2 charon daemon supports start PASS and DROP shunt policies |
b18a697a | 320 | preventing traffic to go through IPsec connections. Installation of the |
107ea60f TB |
321 | shunt policies either via the XFRM netfilter or PFKEYv2 IPsec kernel |
322 | interfaces. | |
f8799170 | 323 | |
93095183 TB |
324 | - The history of policies installed in the kernel is now tracked so that e.g. |
325 | trap policies are correctly updated when reauthenticated SAs are terminated. | |
326 | ||
b18a697a AS |
327 | - IMC/IMV Scanner pair implementing the RFC 5792 PA-TNC (IF-M) protocol. |
328 | Using "netstat -l" the IMC scans open listening ports on the TNC client | |
329 | and sends a port list to the IMV which based on a port policy decides if | |
330 | the client is admitted to the network. | |
331 | (--enable-imc-scanner/--enable-imv-scanner). | |
332 | ||
333 | - IMC/IMV Test pair implementing the RFC 5792 PA-TNC (IF-M) protocol. | |
5d179d19 AS |
334 | (--enable-imc-test/--enable-imv-test). |
335 | ||
4876f896 MW |
336 | - The IKEv2 close action does not use the same value as the ipsec.conf dpdaction |
337 | setting, but the value defined by its own closeaction keyword. The action | |
338 | is triggered if the remote peer closes a CHILD_SA unexpectedly. | |
5d179d19 | 339 | |
5a2e2e0b | 340 | |
6f2378c1 AS |
341 | strongswan-4.5.2 |
342 | ---------------- | |
343 | ||
320e98c2 MW |
344 | - The whitelist plugin for the IKEv2 daemon maintains an in-memory identity |
345 | whitelist. Any connection attempt of peers not whitelisted will get rejected. | |
346 | The 'ipsec whitelist' utility provides a simple command line frontend for | |
347 | whitelist administration. | |
348 | ||
92ebb7c5 | 349 | - The duplicheck plugin provides a specialized form of duplicate checking, |
5832d505 | 350 | doing a liveness check on the old SA and optionally notify a third party |
92ebb7c5 MW |
351 | application about detected duplicates. |
352 | ||
353 | - The coupling plugin permanently couples two or more devices by limiting | |
354 | authentication to previously used certificates. | |
355 | ||
6f2378c1 AS |
356 | - In the case that the peer config and child config don't have the same name |
357 | (usually in SQL database defined connections), ipsec up|route <peer config> | |
358 | starts|routes all associated child configs and ipsec up|route <child config> | |
359 | only starts|routes the specific child config. | |
360 | ||
6ca05fe2 AS |
361 | - fixed the encoding and parsing of X.509 certificate policy statements (CPS). |
362 | ||
1ee7440b AS |
363 | - Duncan Salerno contributed the eap-sim-pcsc plugin implementing a |
364 | pcsc-lite based SIM card backend. | |
365 | ||
366 | - The eap-peap plugin implements the EAP PEAP protocol. Interoperates | |
2778b664 | 367 | successfully with a FreeRADIUS server and Windows 7 Agile VPN clients. |
1ee7440b | 368 | |
cf6ca6d7 MW |
369 | - The IKEv2 daemon charon rereads strongswan.conf on SIGHUP and instructs |
370 | all plugins to reload. Currently only the eap-radius and the attr plugins | |
371 | support configuration reloading. | |
372 | ||
d3d21c29 MW |
373 | - Added userland support to the IKEv2 daemon for Extended Sequence Numbers |
374 | support coming with Linux 2.6.39. To enable ESN on a connection, add | |
375 | the 'esn' keyword to the proposal. The default proposal uses 32-bit sequence | |
376 | numbers only ('noesn'), and the same value is used if no ESN mode is | |
377 | specified. To negotiate ESN support with the peer, include both, e.g. | |
378 | esp=aes128-sha1-esn-noesn. | |
379 | ||
380 | - In addition to ESN, Linux 2.6.39 gained support for replay windows larger | |
381 | than 32 packets. The new global strongswan.conf option 'charon.replay_window' | |
382 | configures the size of the replay window, in packets. | |
383 | ||

388 | - Sansar Choinyambuu implemented the RFC 5793 Posture Broker Protocol (BP) |
389 | compatible with Trusted Network Connect (TNC). The TNCCS 2.0 protocol | |
5cdaafef | 390 | requires the tnccs_20, tnc_imc and tnc_imv plugins but does not depend |
1b7e081b AS |
391 | on the libtnc library. Any available IMV/IMC pairs conforming to the |
392 | Trusted Computing Group's TNC-IF-IMV/IMC 1.2 interface specification | |
e44817df | 393 | can be loaded via /etc/tnc_config. |
1b7e081b | 394 | |
5cdaafef AS |
395 | - Re-implemented the TNCCS 1.1 protocol by using the tnc_imc and tnc_imv |
396 | in place of the external libtnc library. | |
397 | ||
398 | - The tnccs_dynamic plugin loaded on a TNC server in addition to the | |
399 | tnccs_11 and tnccs_20 plugins, dynamically detects the IF-TNCCS | |
400 | protocol version used by a TNC client and invokes an instance of | |
401 | the corresponding protocol stack. | |
402 | ||
41ba5ce7 AS |
403 | - IKE and ESP proposals can now be stored in an SQL database using a |
404 | new proposals table. The start_action field in the child_configs | |
405 | tables allows the automatic starting or routing of connections stored | |
406 | in an SQL database. | |
407 | ||
1b7e081b AS |
408 | - The new certificate_authorities and certificate_distribution_points |
409 | tables make it possible to store CRL and OCSP Certificate Distribution | |
410 | points in an SQL database. | |
411 | ||
ae09bc62 TB |
412 | - The new 'include' statement allows to recursively include other files in |
413 | strongswan.conf. Existing sections and values are thereby extended and | |
414 | replaced, respectively. | |
415 | ||
416 | - Due to the changes in the parser for strongswan.conf, the configuration | |
417 | syntax for the attr plugin has changed. Previously, it was possible to | |
418 | specify multiple values of a specific attribute type by adding multiple | |
419 | key/value pairs with the same key (e.g. dns) to the plugins.attr section. | |
420 | Because values with the same key now replace previously defined values | |
421 | this is not possible anymore. As an alternative, multiple values can be | |
422 | specified by separating them with a comma (e.g. dns = 1.2.3.4, 2.3.4.5). | |
423 | ||
840e7044 AS |
424 | - ipsec listalgs now appends (set in square brackets) to each crypto |
425 | algorithm listed the plugin that registered the function. | |
426 | ||
e44817df MW |
427 | - Traffic Flow Confidentiality padding supported with Linux 2.6.38 can be used |
428 | by the IKEv2 daemon. The ipsec.conf 'tfc' keyword pads all packets to a given | |
429 | boundary, the special value '%mtu' pads all packets to the path MTU. | |
430 | ||
78a547c9 MW |
431 | - The new af-alg plugin can use various crypto primitives of the Linux Crypto |
432 | API using the AF_ALG interface introduced with 2.6.38. This removes the need | |
433 | for additional userland implementations of symmetric cipher, hash, hmac and | |
434 | xcbc algorithms. | |
44582075 | 435 | |
41ed0294 | 436 | - The IKEv2 daemon supports the INITIAL_CONTACT notify as initiator and |
983a5e88 MW |
437 | responder. The notify is sent when initiating configurations with a unique |
438 | policy, set in ipsec.conf via the global 'uniqueids' option. | |
41ed0294 | 439 | |
f0783464 MW |
440 | - The conftest conformance testing framework enables the IKEv2 stack to perform |
441 | many tests using a distinct tool and configuration frontend. Various hooks | |
442 | can alter reserved bits, flags, add custom notifies and proposals, reorder | |
443 | or drop messages and much more. It is enabled using the --enable-conftest | |
444 | ./configure switch. | |
445 | ||
77eee25f MW |
446 | - The new libstrongswan constraints plugin provides advanced X.509 constraint |
447 | checking. In additon to X.509 pathLen constraints, the plugin checks for | |
448 | nameConstraints and certificatePolicies, including policyMappings and | |
449 | policyConstraints. The x509 certificate plugin and the pki tool have been | |
96c4addc MW |
450 | enhanced to support these extensions. The new left/rightcertpolicy ipsec.conf |
451 | connection keywords take OIDs a peer certificate must have. | |
452 | ||
453 | - The left/rightauth ipsec.conf keywords accept values with a minimum strength | |
454 | for trustchain public keys in bits, such as rsa-2048 or ecdsa-256. | |
77eee25f | 455 | |
fb1e7df1 MW |
456 | - The revocation and x509 libstrongswan plugins and the pki tool gained basic |
457 | support for delta CRLs. | |
458 | ||

44582075 MW |
460 | strongswan-4.5.0 |
461 | ---------------- | |
462 | ||
b14923ec AS |
463 | - IMPORTANT: the default keyexchange mode 'ike' is changing with release 4.5 |
464 | from 'ikev1' to 'ikev2', thus commemorating the five year anniversary of the | |
ac544be2 | 465 | IKEv2 RFC 4306 and its mature successor RFC 5996. The time has definitively |
b14923ec | 466 | come for IKEv1 to go into retirement and to cede its place to the much more |
ac544be2 | 467 | robust, powerful and versatile IKEv2 protocol! |
b14923ec | 468 | |
44582075 MW |
469 | - Added new ctr, ccm and gcm plugins providing Counter, Counter with CBC-MAC |
470 | and Galois/Counter Modes based on existing CBC implementations. These | |
471 | new plugins bring support for AES and Camellia Counter and CCM algorithms | |
472 | and the AES GCM algorithms for use in IKEv2. | |
473 | ||
84c9bc42 MW |
474 | - The new pkcs11 plugin brings full Smartcard support to the IKEv2 daemon and |
475 | the pki utility using one or more PKCS#11 libraries. It currently supports | |
61df42cc | 476 | RSA private and public key operations and loads X.509 certificates from |
84c9bc42 MW |
477 | tokens. |
478 | ||
a782b52f MW |
479 | - Implemented a general purpose TLS stack based on crypto and credential |
480 | primitives of libstrongswan. libtls supports TLS versions 1.0, 1.1 and 1.2, | |
481 | ECDHE-ECDSA/RSA, DHE-RSA and RSA key exchange algorithms and RSA/ECDSA based | |
482 | client authentication. | |
483 | ||
484 | - Based on libtls, the eap-tls plugin brings certificate based EAP | |
485 | authentication for client and server. It is compatible to Windows 7 IKEv2 | |
61df42cc | 486 | Smartcard authentication and the OpenSSL based FreeRADIUS EAP-TLS backend. |
a782b52f | 487 | |
8a1353fc AS |
488 | - Implemented the TNCCS 1.1 Trusted Network Connect protocol using the |
489 | libtnc library on the strongSwan client and server side via the tnccs_11 | |
490 | plugin and optionally connecting to a TNC@FHH-enhanced FreeRADIUS AAA server. | |
491 | Depending on the resulting TNC Recommendation, strongSwan clients are granted | |
492 | access to a network behind a strongSwan gateway (allow), are put into a | |
ac544be2 | 493 | remediation zone (isolate) or are blocked (none), respectively. Any number |
8a1353fc AS |
494 | of Integrity Measurement Collector/Verifier pairs can be attached |
495 | via the tnc-imc and tnc-imv charon plugins. | |
496 | ||
b3cabd1f TB |
497 | - The IKEv1 daemon pluto now uses the same kernel interfaces as the IKEv2 |
498 | daemon charon. As a result of this, pluto now supports xfrm marks which | |
499 | were introduced in charon with 4.4.1. | |
500 | ||
501 | - Applets for Maemo 5 (Nokia) allow to easily configure and control IKEv2 | |
502 | based VPN connections with EAP authentication on supported devices. | |
503 | ||
18a4f865 MW |
504 | - The RADIUS plugin eap-radius now supports multiple RADIUS servers for |
505 | redundant setups. Servers are selected by a defined priority, server load and | |
506 | availability. | |
507 | ||
508 | - The simple led plugin controls hardware LEDs through the Linux LED subsystem. | |
509 | It currently shows activity of the IKE daemon and is a good example how to | |
510 | implement a simple event listener. | |
511 | ||
b3cabd1f TB |
512 | - Improved MOBIKE behavior in several corner cases, for instance, if the |
513 | initial responder moves to a different address. | |
514 | ||
515 | - Fixed left-/rightnexthop option, which was broken since 4.4.0. | |
516 | ||
3f84e2d6 AS |
517 | - Fixed a bug not releasing a virtual IP address to a pool if the XAUTH |
518 | identity was different from the IKE identity. | |
519 | ||
f6032361 AS |
520 | - Fixed the alignment of ModeConfig messages on 4-byte boundaries in the |
521 | case where the attributes are not a multiple of 4 bytes (e.g. Cisco's | |
522 | UNITY_BANNER). | |
523 | ||
524 | - Fixed the interoperability of the socket_raw and socket_default | |
525 | charon plugins. | |
526 | ||
3f84e2d6 AS |
527 | - Added man page for strongswan.conf |
528 | ||
a782b52f | 529 | |
03b5e4d8 AS |
530 | strongswan-4.4.1 |
531 | ---------------- | |
532 | ||
ec40c02a | 533 | - Support of xfrm marks in IPsec SAs and IPsec policies introduced |
b22bb9f2 AS |
534 | with the Linux 2.6.34 kernel. For details see the example scenarios |
535 | ikev2/nat-two-rw-mark, ikev2/rw-nat-mark-in-out and ikev2/net2net-psk-dscp. | |
ec40c02a | 536 | |
b22bb9f2 | 537 | - The PLUTO_MARK_IN and PLUTO_ESP_ENC environment variables can be used |
b59340a2 AS |
538 | in a user-specific updown script to set marks on inbound ESP or |
539 | ESP_IN_UDP packets. | |
e87b78c6 | 540 | |
3561cc4b AS |
541 | - The openssl plugin now supports X.509 certificate and CRL functions. |
542 | ||
e9448cfc | 543 | - OCSP/CRL checking in IKEv2 has been moved to the revocation plugin, enabled |
b59340a2 | 544 | by default. Plase update manual load directives in strongswan.conf. |
e9448cfc MW |
545 | |
546 | - RFC3779 ipAddrBlock constraint checking has been moved to the addrblock | |
547 | plugin, disabled by default. Enable it and update manual load directives | |
548 | in strongswan.conf, if required. | |
549 | ||
7f3a9468 MW |
550 | - The pki utility supports CRL generation using the --signcrl command. |
551 | ||
552 | - The ipsec pki --self, --issue and --req commands now support output in | |
553 | PEM format using the --outform pem option. | |
554 | ||
03b5e4d8 AS |
555 | - The major refactoring of the IKEv1 Mode Config functionality now allows |
556 | the transport and handling of any Mode Config attribute. | |
557 | ||
e87b78c6 | 558 | - The RADIUS proxy plugin eap-radius now supports multiple servers. Configured |
b59340a2 AS |
559 | servers are chosen randomly, with the option to prefer a specific server. |
560 | Non-responding servers are degraded by the selection process. | |
e87b78c6 | 561 | |
c5c6f9b6 AS |
562 | - The ipsec pool tool manages arbitrary configuration attributes stored |
563 | in an SQL database. ipsec pool --help gives the details. | |
564 | ||
fe2434cf MW |
565 | - The new eap-simaka-sql plugin acts as a backend for EAP-SIM and EAP-AKA, |
566 | reading triplets/quintuplets from an SQL database. | |
567 | ||
c8bd06c7 MW |
568 | - The High Availability plugin now supports a HA enabled in-memory address |
569 | pool and Node reintegration without IKE_SA rekeying. The latter allows | |
570 | clients without IKE_SA rekeying support to keep connected during | |
571 | reintegration. Additionally, many other issues have been fixed in the ha | |
572 | plugin. | |
1c1f132a | 573 | |
c5c921bf MW |
574 | - Fixed a potential remote code execution vulnerability resulting from |
575 | the misuse of snprintf(). The vulnerability is exploitable by | |
576 | unauthenticated users. | |
577 | ||
03b5e4d8 | 578 | |
00c60592 MW |
579 | strongswan-4.4.0 |
580 | ---------------- | |
581 | ||
d101a61f MW |
582 | - The IKEv2 High Availability plugin has been integrated. It provides |
583 | load sharing and failover capabilities in a cluster of currently two nodes, | |
584 | based on an extend ClusterIP kernel module. More information is available at | |
585 | http://wiki.strongswan.org/projects/strongswan/wiki/HighAvailability. | |
9235edc2 | 586 | The development of the High Availability functionality was sponsored by |
d101a61f MW |
587 | secunet Security Networks AG. |
588 | ||
dd8cb2b0 AS |
589 | - Added IKEv1 and IKEv2 configuration support for the AES-GMAC |
590 | authentication-only ESP cipher. Our aes_gmac kernel patch or a Linux | |
591 | 2.6.34 kernel is required to make AES-GMAC available via the XFRM | |
592 | kernel interface. | |
593 | ||
4590260b MW |
594 | - Added support for Diffie-Hellman groups 22, 23 and 24 to the gmp, gcrypt |
595 | and openssl plugins, usable by both pluto and charon. The new proposal | |
596 | keywords are modp1024s160, modp2048s224 and modp2048s256. Thanks to Joy Latten | |
597 | from IBM for his contribution. | |
598 | ||
9235edc2 AS |
599 | - The IKEv1 pluto daemon supports RAM-based virtual IP pools using |
600 | the rightsourceip directive with a subnet from which addresses | |
601 | are allocated. | |
602 | ||
d6457833 AS |
603 | - The ipsec pki --gen and --pub commands now allow the output of |
604 | private and public keys in PEM format using the --outform pem | |
605 | command line option. | |
606 | ||
2d097a0b MW |
607 | - The new DHCP plugin queries virtual IP addresses for clients from a DHCP |
608 | server using broadcasts, or a defined server using the | |
609 | charon.plugins.dhcp.server strongswan.conf option. DNS/WINS server information | |
610 | is additionally served to clients if the DHCP server provides such | |
611 | information. The plugin is used in ipsec.conf configurations having | |
612 | rightsourceip set to %dhcp. | |
613 | ||
6d6994c6 MW |
614 | - A new plugin called farp fakes ARP responses for virtual IP addresses |
615 | handed out to clients from the IKEv2 daemon charon. The plugin lets a | |
89bf11d2 | 616 | road-warrior act as a client on the local LAN if it uses a virtual IP |
6d6994c6 MW |
617 | from the responders subnet, e.g. acquired using the DHCP plugin. |
618 | ||
00c60592 MW |
619 | - The existing IKEv2 socket implementations have been migrated to the |
620 | socket-default and the socket-raw plugins. The new socket-dynamic plugin | |
621 | binds sockets dynamically to ports configured via the left-/rightikeport | |
622 | ipsec.conf connection parameters. | |
623 | ||
3e6b50ed MW |
624 | - The android charon plugin stores received DNS server information as "net.dns" |
625 | system properties, as used by the Android platform. | |
00c60592 | 626 | |
d6457833 | 627 | |
4c68a85a AS |
628 | strongswan-4.3.6 |
629 | ---------------- | |
630 | ||
cdad91de | 631 | - The IKEv2 daemon supports RFC 3779 IP address block constraints |
e98a4d80 AS |
632 | carried as a critical X.509v3 extension in the peer certificate. |
633 | ||
a7155606 AS |
634 | - The ipsec pool --add|del dns|nbns command manages DNS and NBNS name |
635 | server entries that are sent via the IKEv1 Mode Config or IKEv2 | |
636 | Configuration Payload to remote clients. | |
637 | ||
f721e0fb AS |
638 | - The Camellia cipher can be used as an IKEv1 encryption algorithm. |
639 | ||
4c68a85a AS |
640 | - The IKEv1 and IKEV2 daemons now check certificate path length constraints. |
641 | ||
909c0c3d MW |
642 | - The new ipsec.conf conn option "inactivity" closes a CHILD_SA if no traffic |
643 | was sent or received within the given interval. To close the complete IKE_SA | |
644 | if its only CHILD_SA was inactive, set the global strongswan.conf option | |
aa9eeb5d MW |
645 | "charon.inactivity_close_ike" to yes. |
646 | ||
44e41c4c AS |
647 | - More detailed IKEv2 EAP payload information in debug output |
648 | ||
2b2c69e9 | 649 | - IKEv2 EAP-SIM and EAP-AKA share joint libsimaka library |
44e41c4c | 650 | |
52fd0ef9 MW |
651 | - Added required userland changes for proper SHA256 and SHA384/512 in ESP that |
652 | will be introduced with Linux 2.6.33. The "sha256"/"sha2_256" keyword now | |
653 | configures the kernel with 128 bit truncation, not the non-standard 96 | |
654 | bit truncation used by previous releases. To use the old 96 bit truncation | |
655 | scheme, the new "sha256_96" proposal keyword has been introduced. | |
4c68a85a | 656 | |
2b2c69e9 MW |
657 | - Fixed IPComp in tunnel mode, stripping out the duplicated outer header. This |
658 | change makes IPcomp tunnel mode connections incompatible with previous | |
659 | releases; disable compression on such tunnels. | |
660 | ||
6ec949e0 MW |
661 | - Fixed BEET mode connections on recent kernels by installing SAs with |
662 | appropriate traffic selectors, based on a patch by Michael Rossberg. | |
663 | ||
cdad91de MW |
664 | - Using extensions (such as BEET mode) and crypto algorithms (such as twofish, |
665 | serpent, sha256_96) allocated in the private use space now require that we | |
666 | know its meaning, i.e. we are talking to strongSwan. Use the new | |
667 | "charon.send_vendor_id" option in strongswan.conf to let the remote peer know | |
668 | this is the case. | |
669 | ||
aca9f9ab MW |
670 | - Experimental support for draft-eronen-ipsec-ikev2-eap-auth, where the |
671 | responder omits public key authentication in favor of a mutual authentication | |
672 | method. To enable EAP-only authentication, set rightauth=eap on the responder | |
673 | to rely only on the MSK constructed AUTH payload. This not-yet standardized | |
674 | extension requires the strongSwan vendor ID introduced above. | |
675 | ||
0a975307 AS |
676 | - The IKEv1 daemon ignores the Juniper SRX notification type 40001, thus |
677 | allowing interoperability. | |
678 | ||
679 | ||
b6b90b68 MW |
680 | strongswan-4.3.5 |
681 | ---------------- | |
682 | ||
628f023d AS |
683 | - The IKEv1 pluto daemon can now use SQL-based address pools to deal out |
684 | virtual IP addresses as a Mode Config server. The pool capability has been | |
685 | migrated from charon's sql plugin to a new attr-sql plugin which is loaded | |
b42bfc79 | 686 | by libstrongswan and which can be used by both daemons either with a SQLite |
628f023d AS |
687 | or MySQL database and the corresponding plugin. |
688 | ||
b42bfc79 MW |
689 | - Plugin names have been streamlined: EAP plugins now have a dash after eap |
690 | (e.g. eap-sim), as it is used with the --enable-eap-sim ./configure option. | |
691 | Plugin configuration sections in strongswan.conf now use the same name as the | |
692 | plugin itself (i.e. with a dash). Make sure to update "load" directives and | |
693 | the affected plugin sections in existing strongswan.conf files. | |
694 | ||
d245f5cf AS |
695 | - The private/public key parsing and encoding has been split up into |
696 | separate pkcs1, pgp, pem and dnskey plugins. The public key implementation | |
697 | plugins gmp, gcrypt and openssl can all make use of them. | |
b6b90b68 | 698 | |
55b045ab MW |
699 | - The EAP-AKA plugin can use different backends for USIM/quintuplet |
700 | calculations, very similar to the EAP-SIM plugin. The existing 3GPP2 software | |
701 | implementation has been migrated to a separate plugin. | |
702 | ||
d245f5cf | 703 | - The IKEv2 daemon charon gained basic PGP support. It can use locally installed |
b6b90b68 MW |
704 | peer certificates and can issue signatures based on RSA private keys. |
705 | ||
706 | - The new 'ipsec pki' tool provides a set of commands to maintain a public | |
707 | key infrastructure. It currently supports operations to create RSA and ECDSA | |
708 | private/public keys, calculate fingerprints and issue or verify certificates. | |
709 | ||
710 | - Charon uses a monotonic time source for statistics and job queueing, behaving | |
711 | correctly if the system time changes (e.g. when using NTP). | |
712 | ||
713 | - In addition to time based rekeying, charon supports IPsec SA lifetimes based | |
714 | on processed volume or number of packets. They new ipsec.conf paramaters | |
715 | 'lifetime' (an alias to 'keylife'), 'lifebytes' and 'lifepackets' handle | |
716 | SA timeouts, while the parameters 'margintime' (an alias to rekeymargin), | |
717 | 'marginbytes' and 'marginpackets' trigger the rekeying before a SA expires. | |
718 | The existing parameter 'rekeyfuzz' affects all margins. | |
719 | ||
85af7a89 MW |
720 | - If no CA/Gateway certificate is specified in the NetworkManager plugin, |
721 | charon uses a set of trusted root certificates preinstalled by distributions. | |
722 | The directory containing CA certificates can be specified using the | |
723 | --with-nm-ca-dir=path configure option. | |
724 | ||
b80fa9ca | 725 | - Fixed the encoding of the Email relative distinguished name in left|rightid |
509f70c1 | 726 | statements. |
b80fa9ca | 727 | |
509f70c1 AS |
728 | - Fixed the broken parsing of PKCS#7 wrapped certificates by the pluto daemon. |
729 | ||
730 | - Fixed smartcard-based authentication in the pluto daemon which was broken by | |
731 | the ECDSA support introduced with the 4.3.2 release. | |
732 | ||
cea4bd8f AS |
733 | - A patch contributed by Heiko Hund fixes mixed IPv6 in IPv4 and vice versa |
734 | tunnels established with the IKEv1 pluto daemon. | |
735 | ||
509f70c1 AS |
736 | - The pluto daemon now uses the libstrongswan x509 plugin for certificates and |
737 | CRls and the struct id type was replaced by identification_t used by charon | |
738 | and the libstrongswan library. | |
18060241 | 739 | |
85af7a89 | 740 | |
430dd08a AS |
741 | strongswan-4.3.4 |
742 | ---------------- | |
743 | ||
744 | - IKEv2 charon daemon ported to FreeBSD and Mac OS X. Installation details can | |
745 | be found on wiki.strongswan.org. | |
746 | ||
747 | - ipsec statusall shows the number of bytes transmitted and received over | |
748 | ESP connections configured by the IKEv2 charon daemon. | |
749 | ||
750 | - The IKEv2 charon daemon supports include files in ipsec.secrets. | |

753 | strongswan-4.3.3 |
754 | ---------------- | |
755 | ||
aa74d705 AS |
756 | - The configuration option --enable-integrity-test plus the strongswan.conf |
757 | option libstrongswan.integrity_test = yes activate integrity tests | |
758 | of the IKE daemons charon and pluto, libstrongswan and all loaded | |
759 | plugins. Thus dynamic library misconfigurations and non-malicious file | |
760 | manipulations can be reliably detected. | |
761 | ||
1c7f456a AS |
762 | - The new default setting libstrongswan.ecp_x_coordinate_only=yes allows |
763 | IKEv1 interoperability with MS Windows using the ECP DH groups 19 and 20. | |
764 | ||
765 | - The IKEv1 pluto daemon now supports the AES-CCM and AES-GCM ESP | |
766 | authenticated encryption algorithms. | |
767 | ||
aa74d705 AS |
768 | - The IKEv1 pluto daemon now supports V4 OpenPGP keys. |
769 | ||
770 | - The RDN parser vulnerability discovered by Orange Labs research team | |
771 | was not completely fixed in version 4.3.2. Some more modifications | |
772 | had to be applied to the asn1_length() function to make it robust. | |
773 | ||
1c7f456a | 774 | |
80c0710c MW |
775 | strongswan-4.3.2 |
776 | ---------------- | |
777 | ||
778 | - The new gcrypt plugin provides symmetric cipher, hasher, RNG, Diffie-Hellman | |
779 | and RSA crypto primitives using the LGPL licensed GNU gcrypt library. | |
780 | ||
781 | - libstrongswan features an integrated crypto selftest framework for registered | |
782 | algorithms. The test-vector plugin provides a first set of test vectors and | |
783 | allows pluto and charon to rely on tested crypto algorithms. | |
784 | ||
b32af120 AS |
785 | - pluto can now use all libstrongswan plugins with the exception of x509 and xcbc. |
786 | Thanks to the openssl plugin, the ECP Diffie-Hellman groups 19, 20, 21, 25, and | |
787 | 26 as well as ECDSA-256, ECDSA-384, and ECDSA-521 authentication can be used | |
788 | with IKEv1. | |
126f2130 AS |
789 | |
790 | - Applying their fuzzing tool, the Orange Labs vulnerability research team found | |
791 | another two DoS vulnerabilities, one in the rather old ASN.1 parser of Relative | |
792 | Distinguished Names (RDNs) and a second one in the conversion of ASN.1 UTCTIME | |
793 | and GENERALIZEDTIME strings to a time_t value. | |

3bf7c249 MW |
796 | strongswan-4.3.1 |
797 | ---------------- | |
798 | ||
799 | - The nm plugin now passes DNS/NBNS server information to NetworkManager, | |
09dbca9f | 800 | allowing a gateway administrator to set DNS/NBNS configuration on clients |
3bf7c249 MW |
801 | dynamically. |
802 | ||
09dbca9f MW |
803 | - The nm plugin also accepts CA certificates for gateway authentication. If |
804 | a CA certificate is configured, strongSwan uses the entered gateway address | |
805 | as its idenitity, requiring the gateways certificate to contain the same as | |
806 | subjectAltName. This allows a gateway administrator to deploy the same | |
807 | certificates to Windows 7 and NetworkManager clients. | |
047b2e42 | 808 | |
050cc582 AS |
809 | - The command ipsec purgeike deletes IKEv2 SAs that don't have a CHILD SA. |
810 | The command ipsec down <conn>{n} deletes CHILD SA instance n of connection | |
811 | <conn> whereas ipsec down <conn>{*} deletes all CHILD SA instances. | |
812 | The command ipsec down <conn>[n] deletes IKE SA instance n of connection | |
813 | <conn> plus dependent CHILD SAs whereas ipsec down <conn>[*] deletes all | |
814 | IKE SA instances of connection <conn>. | |
815 | ||
09dbca9f | 816 | - Fixed a regression introduced in 4.3.0 where EAP authentication calculated |
047b2e42 MW |
817 | the AUTH payload incorrectly. Further, the EAP-MSCHAPv2 MSK key derivation |
818 | has been updated to be compatible with the Windows 7 Release Candidate. | |
819 | ||
820 | - Refactored installation of triggering policies. Routed policies are handled | |
821 | outside of IKE_SAs to keep them installed in any case. A tunnel gets | |
822 | established only once, even if initiation is delayed due network outages. | |
823 | ||
050cc582 AS |
824 | - Improved the handling of multiple acquire signals triggered by the kernel. |
825 | ||
826 | - Fixed two DoS vulnerabilities in the charon daemon that were discovered by | |
827 | fuzzing techniques: 1) Sending a malformed IKE_SA_INIT request leaved an | |
828 | incomplete state which caused a null pointer dereference if a subsequent | |
829 | CREATE_CHILD_SA request was sent. 2) Sending an IKE_AUTH request with either | |
830 | a missing TSi or TSr payload caused a null pointer derefence because the | |
b6b90b68 | 831 | checks for TSi and TSr were interchanged. The IKEv2 fuzzer used was |
f3bb1bd0 | 832 | developed by the Orange Labs vulnerability research team. The tool was |
050cc582 AS |
833 | initially written by Gabriel Campana and is now maintained by Laurent Butti. |
834 | ||
047b2e42 MW |
835 | - Added support for AES counter mode in ESP in IKEv2 using the proposal |
836 | keywords aes128ctr, aes192ctr and aes256ctr. | |
837 | ||
d44fd821 | 838 | - Further progress in refactoring pluto: Use of the curl and ldap plugins |
050cc582 AS |
839 | for fetching crls and OCSP. Use of the random plugin to get keying material |
840 | from /dev/random or /dev/urandom. Use of the openssl plugin as an alternative | |
d44fd821 | 841 | to the aes, des, sha1, sha2, and md5 plugins. The blowfish, twofish, and |
050cc582 | 842 | serpent encryption plugins are now optional and are not enabled by default. |
d44fd821 AS |
843 | |
844 | ||
247e665a AS |
845 | strongswan-4.3.0 |
846 | ---------------- | |
847 | ||
81fc8e5f MW |
848 | - Support for the IKEv2 Multiple Authentication Exchanges extension (RFC4739). |
849 | Initiators and responders can use several authentication rounds (e.g. RSA | |
850 | followed by EAP) to authenticate. The new ipsec.conf leftauth/rightauth and | |
851 | leftauth2/rightauth2 parameters define own authentication rounds or setup | |
852 | constraints for the remote peer. See the ipsec.conf man page for more detials. | |
853 | ||
854 | - If glibc printf hooks (register_printf_function) are not available, | |
855 | strongSwan can use the vstr string library to run on non-glibc systems. | |
856 | ||
558c89e7 AS |
857 | - The IKEv2 charon daemon can now configure the ESP CAMELLIA-CBC cipher |
858 | (esp=camellia128|192|256). | |
247e665a | 859 | |
558c89e7 AS |
860 | - Refactored the pluto and scepclient code to use basic functions (memory |
861 | allocation, leak detective, chunk handling, printf_hooks, strongswan.conf | |
862 | attributes, ASN.1 parser, etc.) from the libstrongswan library. | |
b752f873 | 863 | |
558c89e7 AS |
864 | - Up to two DNS and WINS servers to be sent via IKEv1 ModeConfig can be |
865 | configured in the pluto section of strongswan.conf. | |

623bca40 AS |
868 | strongswan-4.2.14 |
869 | ----------------- | |
870 | ||
22180558 | 871 | - The new server-side EAP RADIUS plugin (--enable-eap-radius) |
f3bb1bd0 | 872 | relays EAP messages to and from a RADIUS server. Successfully |
22180558 AS |
873 | tested with with a freeradius server using EAP-MD5 and EAP-SIM. |
874 | ||
79b27294 AS |
875 | - A vulnerability in the Dead Peer Detection (RFC 3706) code was found by |
876 | Gerd v. Egidy <gerd.von.egidy@intra2net.com> of Intra2net AG affecting | |
877 | all Openswan and strongSwan releases. A malicious (or expired ISAKMP) | |
878 | R_U_THERE or R_U_THERE_ACK Dead Peer Detection packet can cause the | |
879 | pluto IKE daemon to crash and restart. No authentication or encryption | |
880 | is required to trigger this bug. One spoofed UDP packet can cause the | |
881 | pluto IKE daemon to restart and be unresponsive for a few seconds while | |
882 | restarting. This DPD null state vulnerability has been officially | |
883 | registered as CVE-2009-0790 and is fixed by this release. | |
884 | ||
22180558 AS |
885 | - ASN.1 to time_t conversion caused a time wrap-around for |
886 | dates after Jan 18 03:14:07 UTC 2038 on 32-bit platforms. | |
887 | As a workaround such dates are set to the maximum representable | |
888 | time, i.e. Jan 19 03:14:07 UTC 2038. | |
889 | ||
890 | - Distinguished Names containing wildcards (*) are not sent in the | |
b6b90b68 | 891 | IDr payload anymore. |
623bca40 AS |
892 | |
893 | ||
076e7853 AS |

895 | ----------------- | |
896 | ||
897 | - Fixed a use-after-free bug in the DPD timeout section of the | |
898 | IKEv1 pluto daemon which sporadically caused a segfault. | |
899 | ||
f3bb1bd0 | 900 | - Fixed a crash in the IKEv2 charon daemon occurring with |
b6b90b68 | 901 | mixed RAM-based and SQL-based virtual IP address pools. |
076e7853 | 902 | |
f15483ef AS |
903 | - Fixed ASN.1 parsing of algorithmIdentifier objects where the |
904 | parameters field is optional. | |
905 | ||
03991bc1 MW |
906 | - Ported nm plugin to NetworkManager 7.1. |
907 | ||
076e7853 | 908 | |
bfde75ee | 909 | strongswan-4.2.12 |
076e7853 | 910 | ----------------- |
bfde75ee AS |
911 | |
912 | - Support of the EAP-MSCHAPv2 protocol enabled by the option | |
913 | --enable-eap-mschapv2. Requires the MD4 hash algorithm enabled | |
914 | either by --enable-md4 or --enable-openssl. | |
915 | ||
916 | - Assignment of up to two DNS and up to two WINS servers to peers via | |
b6b90b68 | 917 | the IKEv2 Configuration Payload (CP). The IPv4 or IPv6 nameserver |
bfde75ee AS |
918 | addresses are defined in strongswan.conf. |
919 | ||
920 | - The strongSwan applet for the Gnome NetworkManager is now built and | |
921 | distributed as a separate tarball under the name NetworkManager-strongswan. | |
922 | ||
b6b90b68 | 923 | |
0519ca90 AS |
924 | strongswan-4.2.11 |
925 | ----------------- | |
926 | ||
ae1ae574 AS |
927 | - Fixed ESP NULL encryption broken by the refactoring of keymat.c. |
928 | Also introduced proper initialization and disposal of keying material. | |
929 | ||
930 | - Fixed the missing listing of connection definitions in ipsec statusall | |
931 | broken by an unfortunate local variable overload. | |
0519ca90 AS |
932 | |
933 | ||
4856241c MW |
934 | strongswan-4.2.10 |
935 | ----------------- | |
936 | ||
937 | - Several performance improvements to handle thousands of tunnels with almost | |
938 | linear upscaling. All relevant data structures have been replaced by faster | |
939 | counterparts with better lookup times. | |
940 | ||
941 | - Better parallelization to run charon on multiple cores. Due to improved | |
942 | ressource locking and other optimizations the daemon can take full | |
943 | advantage of 16 or even more cores. | |
944 | ||
945 | - The load-tester plugin can use a NULL Diffie-Hellman group and simulate | |
946 | unique identities and certificates by signing peer certificates using a CA | |
947 | on the fly. | |
948 | ||
949 | - The redesigned stroke in-memory IP pool handles leases. The "ipsec leases" | |
950 | command queries assigned leases. | |
951 | ||
952 | - Added support for smartcards in charon by using the ENGINE API provided by | |
953 | OpenSSL, based on patches by Michael RoĂŸberg. | |
954 | ||
955 | - The Padlock plugin supports the hardware RNG found on VIA CPUs to provide a | |
956 | reliable source of randomness. | |
957 | ||
73937bd8 MW |
958 | strongswan-4.2.9 |
959 | ---------------- | |
960 | ||
509e07c5 AS |
961 | - Flexible configuration of logging subsystem allowing to log to multiple |
962 | syslog facilities or to files using fine-grained log levels for each target. | |
73937bd8 MW |
963 | |
964 | - Load testing plugin to do stress testing of the IKEv2 daemon against self | |
965 | or another host. Found and fixed issues during tests in the multi-threaded | |
966 | use of the OpenSSL plugin. | |
967 | ||
968 | - Added profiling code to synchronization primitives to find bottlenecks if | |
7bdc931e | 969 | running on multiple cores. Found and fixed an issue where parts of the |
73937bd8 MW |
970 | Diffie-Hellman calculation acquired an exclusive lock. This greatly improves |
971 | parallelization to multiple cores. | |
972 | ||
509e07c5 AS |
973 | - updown script invocation has been separated into a plugin of its own to |
974 | further slim down the daemon core. | |
73937bd8 | 975 | |
509e07c5 | 976 | - Separated IKE_SA/CHILD_SA key derivation process into a closed system, |
7bdc931e | 977 | allowing future implementations to use a secured environment in e.g. kernel |
73937bd8 MW |
978 | memory or hardware. |
979 | ||
509e07c5 AS |
980 | - The kernel interface of charon has been modularized. XFRM NETLINK (default) |
981 | and PFKEY (--enable-kernel-pfkey) interface plugins for the native IPsec | |
982 | stack of the Linux 2.6 kernel as well as a PFKEY interface for the KLIPS | |
983 | IPsec stack (--enable-kernel-klips) are provided. | |
984 | ||
985 | - Basic Mobile IPv6 support has been introduced, securing Binding Update | |
986 | messages as well as tunneled traffic between Mobile Node and Home Agent. | |
987 | The installpolicy=no option allows peaceful cooperation with a dominant | |
988 | mip6d daemon and the new type=transport_proxy implements the special MIPv6 | |
989 | IPsec transport proxy mode where the IKEv2 daemon uses the Care-of-Address | |
f3bb1bd0 | 990 | but the IPsec SA is set up for the Home Address. |
7bdc931e | 991 | |
4dc0dce8 AS |
992 | - Implemented migration of Mobile IPv6 connections using the KMADDRESS |
993 | field contained in XFRM_MSG_MIGRATE messages sent by the mip6d daemon | |
994 | via the Linux 2.6.28 (or appropriately patched) kernel. | |

e39b271b AS |
997 | strongswan-4.2.8 |
998 | ---------------- | |
999 | ||
5dadb16e | 1000 | - IKEv2 charon daemon supports authentication based on raw public keys |
e39b271b AS |
1001 | stored in the SQL database backend. The ipsec listpubkeys command |
1002 | lists the available raw public keys via the stroke interface. | |
1003 | ||
4f0241e6 MW |
1004 | - Several MOBIKE improvements: Detect changes in NAT mappings in DPD exchanges, |
1005 | handle events if kernel detects NAT mapping changes in UDP-encapsulated | |
1006 | ESP packets (requires kernel patch), reuse old addesses in MOBIKE updates as | |
1007 | long as possible and other fixes. | |
1008 | ||
5dadb16e AS |
1009 | - Fixed a bug in addr_in_subnet() which caused insertion of wrong source |
1010 | routes for destination subnets having netwmasks not being a multiple of 8 bits. | |
1011 | Thanks go to Wolfgang Steudel, TU Ilmenau for reporting this bug. | |
1012 | ||

1014 | strongswan-4.2.7 |
1015 | ---------------- | |
1016 | ||
b37cda82 AS |
1017 | - Fixed a Denial-of-Service vulnerability where an IKE_SA_INIT message with |
1018 | a KE payload containing zeroes only can cause a crash of the IKEv2 charon | |
1019 | daemon due to a NULL pointer returned by the mpz_export() function of the | |
1020 | GNU Multiprecision Library (GMP). Thanks go to Mu Dynamics Research Labs | |
b6b90b68 | 1021 | for making us aware of this problem. |
b37cda82 | 1022 | |
b6b90b68 | 1023 | - The new agent plugin provides a private key implementation on top of an |
e376d75f MW |
1024 | ssh-agent. |
1025 | ||
1026 | - The NetworkManager plugin has been extended to support certificate client | |
b1f47854 | 1027 | authentication using RSA keys loaded from a file or using ssh-agent. |
e376d75f MW |
1028 | |
1029 | - Daemon capability dropping has been ported to libcap and must be enabled | |
1030 | explicitly --with-capabilities=libcap. Future version will support the | |
1031 | newer libcap2 library. | |
1032 | ||
b37cda82 AS |
1033 | - ipsec listalgs lists the IKEv2 cryptografic algorithms registered with the |
1034 | charon keying daemon. | |

1037 | strongswan-4.2.6 |
1038 | ---------------- | |
1039 | ||
609166f4 MW |
1040 | - A NetworkManager plugin allows GUI-based configuration of road-warrior |
1041 | clients in a simple way. It features X509 based gateway authentication | |
1042 | and EAP client authentication, tunnel setup/teardown and storing passwords | |
1043 | in the Gnome Keyring. | |
1044 | ||
1045 | - A new EAP-GTC plugin implements draft-sheffer-ikev2-gtc-00.txt and allows | |
1046 | username/password authentication against any PAM service on the gateway. | |
b6b90b68 | 1047 | The new EAP method interacts nicely with the NetworkManager plugin and allows |
609166f4 MW |
1048 | client authentication against e.g. LDAP. |
1049 | ||
1050 | - Improved support for the EAP-Identity method. The new ipsec.conf eap_identity | |
1051 | parameter defines an additional identity to pass to the server in EAP | |
1052 | authentication. | |
1053 | ||
9f9d6ece AS |
1054 | - The "ipsec statusall" command now lists CA restrictions, EAP |
1055 | authentication types and EAP identities. | |
1056 | ||
1057 | - Fixed two multithreading deadlocks occurring when starting up | |
1058 | several hundred tunnels concurrently. | |
1059 | ||
1060 | - Fixed the --enable-integrity-test configure option which | |
1061 | computes a SHA-1 checksum over the libstrongswan library. | |

8124e491 AS |
1068 | |
1069 | - Improved the performance of the SQL-based virtual IP address pool | |
1070 | by introducing an additional addresses table. The leases table | |
1071 | storing only history information has become optional and can be | |
1072 | disabled by setting charon.plugins.sql.lease_history = no in | |
1073 | strongswan.conf. | |
1074 | ||
eb0cc338 | 1075 | - The XFRM_STATE_AF_UNSPEC flag added to xfrm.h allows IPv4-over-IPv6 |
de5f70e7 | 1076 | and IPv6-over-IPv4 tunnels with the 2.6.26 and later Linux kernels. |
eb0cc338 | 1077 | |
174216c7 AS |
1078 | - management of different virtual IP pools for different |
1079 | network interfaces have become possible. | |

1095 | |
1096 | - The openssl plugin supports the elliptic curve Diffie-Hellman groups | |
1097 | 19, 20, 21, 25, and 26. | |
1098 | ||
1099 | - The openssl plugin supports ECDSA authentication using elliptic curve | |
1100 | X.509 certificates. | |
1101 | ||
1102 | - Fixed a bug in stroke which caused multiple charon threads to close | |
1103 | the file descriptors during packet transfers over the stroke socket. | |
b6b90b68 | 1104 | |
e0bb4dbb AS |
1105 | - ESP sequence numbers are now migrated in IPsec SA updates handled by |
1106 | MOBIKE. Works only with Linux kernels >= 2.6.17. | |

1121 | ||
a57cd446 AS |
1122 | - Plugins for libstrongswan and charon can optionally be loaded according |
1123 | to a configuration in strongswan.conf. Most components provide a | |
7f491111 | 1124 | "load = " option followed by a space separated list of plugins to load. |
a57cd446 AS |
1125 | This allows e.g. the fallback from a hardware crypto accelerator to |
1126 | to software-based crypto plugins. | |
7f491111 MW |
1127 | |
1128 | - Charons SQL plugin has been extended by a virtual IP address pool. | |
a57cd446 AS |
1129 | Configurations with a rightsourceip=%poolname setting query a SQLite or |
1130 | MySQL database for leases. The "ipsec pool" command helps in administrating | |
1131 | the pool database. See ipsec pool --help for the available options | |
1132 | ||
1133 | - The Authenticated Encryption Algorithms AES-CCM-8/12/16 and AES-GCM-8/12/16 | |
b6b90b68 | 1134 | for ESP are now supported starting with the Linux 2.6.25 kernel. The |
a57cd446 AS |
1135 | syntax is e.g. esp=aes128ccm12 or esp=aes256gcm16. |
1136 | ||
7f491111 | 1137 | |
5c5d67d6 AS |
1138 | strongswan-4.2.1 |
1139 | ---------------- | |
1140 | ||
c306dfb1 | 1141 | - Support for "Hash and URL" encoded certificate payloads has been implemented |
b1f8fc0c TB |
1142 | in the IKEv2 daemon charon. Using the "certuribase" option of a CA section |
1143 | allows to assign a base URL to all certificates issued by the specified CA. | |
1144 | The final URL is then built by concatenating that base and the hex encoded | |
1145 | SHA1 hash of the DER encoded certificate. Note that this feature is disabled | |
1146 | by default and must be enabled using the option "charon.hash_and_url". | |
5c5d67d6 | 1147 | |
58caabf7 MW |
1148 | - The IKEv2 daemon charon now supports the "uniqueids" option to close multiple |
1149 | IKE_SAs with the same peer. The option value "keep" prefers existing | |
1150 | connection setups over new ones, where the value "replace" replaces existing | |
1151 | connections. | |
b6b90b68 | 1152 | |
f3bb1bd0 | 1153 | - The crypto factory in libstrongswan additionally supports random number |
58caabf7 | 1154 | generators, plugins may provide other sources of randomness. The default |
c306dfb1 | 1155 | plugin reads raw random data from /dev/(u)random. |
58caabf7 | 1156 | |
b6b90b68 | 1157 | - Extended the credential framework by a caching option to allow plugins |
58caabf7 | 1158 | persistent caching of fetched credentials. The "cachecrl" option has been |
c306dfb1 | 1159 | re-implemented. |
58caabf7 MW |
1160 | |
1161 | - The new trustchain verification introduced in 4.2.0 has been parallelized. | |
1162 | Threads fetching CRL or OCSP information no longer block other threads. | |
5c5d67d6 | 1163 | |
58caabf7 MW |
1164 | - A new IKEv2 configuration attribute framework has been introduced allowing |
1165 | plugins to provide virtual IP addresses, and in the future, other | |
1166 | configuration attribute services (e.g. DNS/WINS servers). | |
5c5d67d6 | 1167 | |
466abb49 | 1168 | - The stroke plugin has been extended to provide virtual IP addresses from |
58caabf7 MW |
1169 | a pool defined in ipsec.conf. The "rightsourceip" parameter now accepts |
1170 | address pools in CIDR notation (e.g. 10.1.1.0/24). The parameter also accepts | |
1171 | the value "%poolname", where "poolname" identifies a pool provided by a | |
466abb49 | 1172 | separate plugin. |
58caabf7 | 1173 | |
c306dfb1 | 1174 | - Fixed compilation on uClibc and a couple of other minor bugs. |
58caabf7 | 1175 | |
c306dfb1 | 1176 | - Set DPD defaults in ipsec starter to dpd_delay=30s and dpd_timeout=150s. |
466abb49 AS |
1177 | |
1178 | - The IKEv1 pluto daemon now supports the ESP encryption algorithm CAMELLIA | |
c306dfb1 | 1179 | with key lengths of 128, 192, and 256 bits, as well as the authentication |
466abb49 AS |
1180 | algorithm AES_XCBC_MAC. Configuration example: esp=camellia192-aesxcbc. |

1183 | strongswan-4.2.0 |
1184 | ---------------- | |
1185 | ||
16f5dacd MW |
1186 | - libstrongswan has been modularized to attach crypto algorithms, |
1187 | credential implementations (keys, certificates) and fetchers dynamically | |
1188 | through plugins. Existing code has been ported to plugins: | |
1189 | - RSA/Diffie-Hellman implementation using the GNU Multi Precision library | |
1190 | - X509 certificate system supporting CRLs, OCSP and attribute certificates | |
1191 | - Multiple plugins providing crypto algorithms in software | |
1192 | - CURL and OpenLDAP fetcher | |
a11ea97d | 1193 | |
16f5dacd MW |
1194 | - libstrongswan gained a relational database API which uses pluggable database |
1195 | providers. Plugins for MySQL and SQLite are available. | |
1196 | ||
1197 | - The IKEv2 keying daemon charon is more extensible. Generic plugins may provide | |
1198 | connection configuration, credentials and EAP methods or control the daemon. | |
1199 | Existing code has been ported to plugins: | |
1200 | - EAP-AKA, EAP-SIM, EAP-MD5 and EAP-Identity | |
1201 | - stroke configuration, credential and control (compatible to pluto) | |
1202 | - XML bases management protocol to control and query the daemon | |
1203 | The following new plugins are available: | |
1204 | - An experimental SQL configuration, credential and logging plugin on | |
1205 | top of either MySQL or SQLite | |
1206 | - A unit testing plugin to run tests at daemon startup | |
1207 | ||
1208 | - The authentication and credential framework in charon has been heavily | |
1209 | refactored to support modular credential providers, proper | |
1210 | CERTREQ/CERT payload exchanges and extensible authorization rules. | |
1211 | ||
b6b90b68 | 1212 | - The framework of strongSwan Manager has envolved to the web application |
16f5dacd MW |
1213 | framework libfast (FastCGI Application Server w/ Templates) and is usable |
1214 | by other applications. | |

1217 | strongswan-4.1.11 |
1218 | ----------------- | |
fb6d76cd | 1219 | |
a561f74d AS |
1220 | - IKE rekeying in NAT situations did not inherit the NAT conditions |
1221 | to the rekeyed IKE_SA so that the UDP encapsulation was lost with | |
1222 | the next CHILD_SA rekeying. | |
1223 | ||
1224 | - Wrong type definition of the next_payload variable in id_payload.c | |
b6b90b68 | 1225 | caused an INVALID_SYNTAX error on PowerPC platforms. |
fb6d76cd | 1226 | |
e6b50b3f AS |
1227 | - Implemented IKEv2 EAP-SIM server and client test modules that use |
1228 | triplets stored in a file. For details on the configuration see | |
1229 | the scenario 'ikev2/rw-eap-sim-rsa'. | |
1230 | ||
fb6d76cd | 1231 | |
83e0d841 AS |
1232 | strongswan-4.1.10 |
1233 | ----------------- | |
1234 | ||
1235 | - Fixed error in the ordering of the certinfo_t records in the ocsp cache that | |
b6b90b68 | 1236 | caused multiple entries of the same serial number to be created. |
83e0d841 | 1237 | |
fdc7c943 MW |
1238 | - Implementation of a simple EAP-MD5 module which provides CHAP |
1239 | authentication. This may be interesting in conjunction with certificate | |
1240 | based server authentication, as weak passwords can't be brute forced | |
1241 | (in contradiction to traditional IKEv2 PSK). | |
1242 | ||
1243 | - A complete software based implementation of EAP-AKA, using algorithms | |
1244 | specified in 3GPP2 (S.S0055). This implementation does not use an USIM, | |
1245 | but reads the secrets from ipsec.secrets. Make sure to read eap_aka.h | |
1246 | before using it. | |
1247 | ||
1248 | - Support for vendor specific EAP methods using Expanded EAP types. The | |
b6b90b68 | 1249 | interface to EAP modules has been slightly changed, so make sure to |
fdc7c943 | 1250 | check the changes if you're already rolling your own modules. |
83e0d841 | 1251 | |
fb6d76cd | 1252 | |
5076770c AS |
1253 | strongswan-4.1.9 |
1254 | ---------------- | |
1255 | ||
800b3356 AS |
1256 | - The default _updown script now dynamically inserts and removes ip6tables |
1257 | firewall rules if leftfirewall=yes is set in IPv6 connections. New IPv6 | |
1258 | net-net and roadwarrior (PSK/RSA) scenarios for both IKEv1 and IKEV2 were | |
1259 | added. | |
5076770c | 1260 | |
6f274c2a MW |
1261 | - Implemented RFC4478 repeated authentication to force EAP/Virtual-IP clients |
1262 | to reestablish an IKE_SA within a given timeframe. | |
1263 | ||
1264 | - strongSwan Manager supports configuration listing, initiation and termination | |
1265 | of IKE and CHILD_SAs. | |
1266 | ||
1267 | - Fixes and improvements to multithreading code. | |
1268 | ||
8b678ad4 | 1269 | - IKEv2 plugins have been renamed to libcharon-* to avoid naming conflicts. |
b6b90b68 | 1270 | Make sure to remove the old plugins in $libexecdir/ipsec, otherwise they get |
8b678ad4 | 1271 | loaded twice. |
5076770c | 1272 | |
83e0d841 | 1273 | |
b82e8231 AS |
1274 | strongswan-4.1.8 |
1275 | ---------------- | |
1276 | ||
5076770c | 1277 | - Removed recursive pthread mutexes since uClibc doesn't support them. |
b82e8231 AS |
1278 | |
1279 | ||
a4a3632c AS |
1280 | strongswan-4.1.7 |
1281 | ---------------- | |
1282 | ||
1283 | - In NAT traversal situations and multiple queued Quick Modes, | |
1284 | those pending connections inserted by auto=start after the | |
1285 | port floating from 500 to 4500 were erronously deleted. | |
1286 | ||
6e193274 | 1287 | - Added a "forceencaps" connection parameter to enforce UDP encapsulation |
078b6008 | 1288 | to surmount restrictive firewalls. NAT detection payloads are faked to |
6e193274 MW |
1289 | simulate a NAT situation and trick the other peer into NAT mode (IKEv2 only). |
1290 | ||
1291 | - Preview of strongSwan Manager, a web based configuration and monitoring | |
1292 | application. It uses a new XML control interface to query the IKEv2 daemon | |
64d24679 | 1293 | (see http://wiki.strongswan.org/wiki/Manager). |
6e193274 MW |
1294 | |
1295 | - Experimental SQLite configuration backend which will provide the configuration | |
1296 | interface for strongSwan Manager in future releases. | |
1297 | ||
1298 | - Further improvements to MOBIKE support. | |
1299 | ||
a4a3632c | 1300 | |
3dcf9dbd AS |
1301 | strongswan-4.1.6 |
1302 | ---------------- | |
1303 | ||
3eac4dfd AS |
1304 | - Since some third party IKEv2 implementations run into |
1305 | problems with strongSwan announcing MOBIKE capability per | |
1306 | default, MOBIKE can be disabled on a per-connection-basis | |
1307 | using the mobike=no option. Whereas mobike=no disables the | |
1308 | sending of the MOBIKE_SUPPORTED notification and the floating | |
1309 | to UDP port 4500 with the IKE_AUTH request even if no NAT | |
1310 | situation has been detected, strongSwan will still support | |
1311 | MOBIKE acting as a responder. | |
1312 | ||
1313 | - the default ipsec routing table plus its corresponding priority | |
1314 | used for inserting source routes has been changed from 100 to 220. | |
1315 | It can be configured using the --with-ipsec-routing-table and | |
b6b90b68 MW |
1316 | --with-ipsec-routing-table-prio options. |
1317 | ||
bdc0b55b AS |
1318 | - the --enable-integrity-test configure option tests the |
1319 | integrity of the libstrongswan crypto code during the charon | |
1320 | startup. | |
b6b90b68 | 1321 | |
3eac4dfd AS |
1322 | - the --disable-xauth-vid configure option disables the sending |
1323 | of the XAUTH vendor ID. This can be used as a workaround when | |
1324 | interoperating with some Windows VPN clients that get into | |
1325 | trouble upon reception of an XAUTH VID without eXtended | |
1326 | AUTHentication having been configured. | |
b6b90b68 | 1327 | |
f872f9d1 AS |
1328 | - ipsec stroke now supports the rereadsecrets, rereadaacerts, |
1329 | rereadacerts, and listacerts options. | |
3dcf9dbd AS |
1330 | |
1331 | ||
7ad634a2 AS |
1332 | strongswan-4.1.5 |
1333 | ---------------- | |
1334 | ||
1335 | - If a DNS lookup failure occurs when resolving right=%<FQDN> | |
1336 | or right=<FQDN> combined with rightallowany=yes then the | |
1337 | connection is not updated by ipsec starter thus preventing | |
1338 | the disruption of an active IPsec connection. Only if the DNS | |
1339 | lookup successfully returns with a changed IP address the | |
1340 | corresponding connection definition is updated. | |
1341 | ||
8f5b363c MW |
1342 | - Routes installed by the keying daemons are now in a separate |
1343 | routing table with the ID 100 to avoid conflicts with the main | |
1344 | table. Route lookup for IKEv2 traffic is done in userspace to ignore | |
1345 | routes installed for IPsec, as IKE traffic shouldn't get encapsulated. | |
1346 | ||
7ad634a2 | 1347 | |
e93c68ba AS |
1348 | strongswan-4.1.4 |
1349 | ---------------- | |
1350 | ||
1351 | - The pluto IKEv1 daemon now exhibits the same behaviour as its | |
1352 | IKEv2 companion charon by inserting an explicit route via the | |
1353 | _updown script only if a sourceip exists. This is admissible | |
1354 | since routing through the IPsec tunnel is handled automatically | |
b7af55ac AS |
1355 | by NETKEY's IPsec policies. As a consequence the left|rightnexthop |
1356 | parameter is not required any more. | |
078ce348 AS |
1357 | |
1358 | - The new IKEv1 parameter right|leftallowany parameters helps to handle | |
1359 | the case where both peers possess dynamic IP addresses that are | |
1360 | usually resolved using DynDNS or a similar service. The configuration | |
1361 | ||
1362 | right=peer.foo.bar | |
1363 | rightallowany=yes | |
1364 | ||
1365 | can be used by the initiator to start up a connection to a peer | |
1366 | by resolving peer.foo.bar into the currently allocated IP address. | |
1367 | Thanks to the rightallowany flag the connection behaves later on | |
1368 | as | |
1369 | ||
1370 | right=%any | |
1371 | ||
1372 | so that the peer can rekey the connection as an initiator when his | |
1fbdab85 AS |
1373 | IP address changes. An alternative notation is |
1374 | ||
1375 | right=%peer.foo.bar | |
1376 | ||
1377 | which will implicitly set rightallowany=yes. | |
1378 | ||
1379 | - ipsec starter now fails more gracefully in the presence of parsing | |
1380 | errors. Flawed ca and conn section are discarded and pluto is started | |
1381 | if non-fatal errors only were encountered. If right=%peer.foo.bar | |
1382 | cannot be resolved by DNS then right=%any will be used so that passive | |
1383 | connections as a responder are still possible. | |
078ce348 | 1384 | |
a0a0bdd7 AS |
1385 | - The new pkcs11initargs parameter that can be placed in the |
1386 | setup config section of /etc/ipsec.conf allows the definition | |
1387 | of an argument string that is used with the PKCS#11 C_Initialize() | |
1388 | function. This non-standard feature is required by the NSS softoken | |
1389 | library. This patch was contributed by Robert Varga. | |
b6b90b68 | 1390 | |
a0a0bdd7 AS |
1391 | - Fixed a bug in ipsec starter introduced by strongswan-2.8.5 |
1392 | which caused a segmentation fault in the presence of unknown | |
1393 | or misspelt keywords in ipsec.conf. This bug fix was contributed | |
1394 | by Robert Varga. | |
1395 | ||
e3606f2b MW |
1396 | - Partial support for MOBIKE in IKEv2. The initiator acts on interface/ |
1397 | address configuration changes and updates IKE and IPsec SAs dynamically. | |
e93c68ba | 1398 | |
06651827 | 1399 | |
a3354a69 AS |
1400 | strongswan-4.1.3 |
1401 | ---------------- | |
1402 | ||
b6b90b68 | 1403 | - IKEv2 peer configuration selection now can be based on a given |
35d4809c AS |
1404 | certification authority using the rightca= statement. |
1405 | ||
1406 | - IKEv2 authentication based on RSA signatures now can handle multiple | |
41e16cf4 AS |
1407 | certificates issued for a given peer ID. This allows a smooth transition |
1408 | in the case of a peer certificate renewal. | |
a3354a69 | 1409 | |
998ca0ea MW |
1410 | - IKEv2: Support for requesting a specific virtual IP using leftsourceip on the |
1411 | client and returning requested virtual IPs using rightsourceip=%config | |
1412 | on the server. If the server does not support configuration payloads, the | |
1413 | client enforces its leftsourceip parameter. | |
1414 | ||
1415 | - The ./configure options --with-uid/--with-gid allow pluto and charon | |
1416 | to drop their privileges to a minimum and change to an other UID/GID. This | |
1417 | improves the systems security, as a possible intruder may only get the | |
1418 | CAP_NET_ADMIN capability. | |
1419 | ||
b6b90b68 | 1420 | - Further modularization of charon: Pluggable control interface and |
998ca0ea MW |
1421 | configuration backend modules provide extensibility. The control interface |
1422 | for stroke is included, and further interfaces using DBUS (NetworkManager) | |
1423 | or XML are on the way. A backend for storing configurations in the daemon | |
b6b90b68 | 1424 | is provided and more advanced backends (using e.g. a database) are trivial |
998ca0ea | 1425 | to implement. |
a3354a69 | 1426 | |
f3bb1bd0 | 1427 | - Fixed a compilation failure in libfreeswan occurring with Linux kernel |
41e16cf4 AS |
1428 | headers > 2.6.17. |
1429 | ||
1430 | ||
8ea7b96f AS |
1431 | strongswan-4.1.2 |
1432 | ---------------- | |
1433 | ||
e23d98a7 | 1434 | - Support for an additional Diffie-Hellman exchange when creating/rekeying |
37fb0355 MW |
1435 | a CHILD_SA in IKEv2 (PFS). PFS is enabled when the proposal contains a |
1436 | DH group (e.g. "esp=aes128-sha1-modp1536"). Further, DH group negotiation | |
1437 | is implemented properly for rekeying. | |
1438 | ||
1439 | - Support for the AES-XCBC-96 MAC algorithm for IPsec SAs when using IKEv2 | |
1440 | (requires linux >= 2.6.20). It is enabled using e.g. "esp=aes256-aesxcbc". | |
1441 | ||
d931f465 MW |
1442 | - Working IPv4-in-IPv6 and IPv6-in-IPv4 tunnels for linux >= 2.6.21. |
1443 | ||
37fb0355 MW |
1444 | - Added support for EAP modules which do not establish an MSK. |
1445 | ||
dfbe2a0f | 1446 | - Removed the dependencies from the /usr/include/linux/ headers by |
9f78f957 | 1447 | including xfrm.h, ipsec.h, and pfkeyv2.h in the distribution. |
b6b90b68 | 1448 | |
9f78f957 AS |
1449 | - crlNumber is now listed by ipsec listcrls |
1450 | ||
8ea7b96f AS |
1451 | - The xauth_modules.verify_secret() function now passes the |
1452 | connection name. | |
1453 | ||
e23d98a7 | 1454 | |
ed284399 MW |
1455 | strongswan-4.1.1 |
1456 | ---------------- | |
1457 | ||
1458 | - Server side cookie support. If to may IKE_SAs are in CONNECTING state, | |
1459 | cookies are enabled and protect against DoS attacks with faked source | |
1460 | addresses. Number of IKE_SAs in CONNECTING state is also limited per | |
1461 | peer address to avoid resource exhaustion. IKE_SA_INIT messages are | |
1462 | compared to properly detect retransmissions and incoming retransmits are | |
1463 | detected even if the IKE_SA is blocked (e.g. doing OCSP fetches). | |
1464 | ||
db88e37d AS |
1465 | - The IKEv2 daemon charon now supports dynamic http- and ldap-based CRL |
1466 | fetching enabled by crlcheckinterval > 0 and caching fetched CRLs | |
1467 | enabled by cachecrls=yes. | |
1468 | ||
3b4f7d92 AS |
1469 | - Added the configuration options --enable-nat-transport which enables |
1470 | the potentially insecure NAT traversal for IPsec transport mode and | |
1471 | --disable-vendor-id which disables the sending of the strongSwan | |
1472 | vendor ID. | |
1473 | ||
1474 | - Fixed a long-standing bug in the pluto IKEv1 daemon which caused | |
1475 | a segmentation fault if a malformed payload was detected in the | |
1476 | IKE MR2 message and pluto tried to send an encrypted notification | |
1477 | message. | |
1478 | ||
46b9ff68 AS |
1479 | - Added the NATT_IETF_02_N Vendor ID in order to support IKEv1 connections |
1480 | with Windows 2003 Server which uses a wrong VID hash. | |
1481 | ||
3b4f7d92 | 1482 | |
34bbd0c3 | 1483 | strongswan-4.1.0 |
cd3958f8 AS |
1484 | ---------------- |
1485 | ||
1486 | - Support of SHA2_384 hash function for protecting IKEv1 | |
1487 | negotiations and support of SHA2 signatures in X.509 certificates. | |
1488 | ||
1489 | - Fixed a serious bug in the computation of the SHA2-512 HMAC | |
1490 | function. Introduced automatic self-test of all IKEv1 hash | |
1491 | and hmac functions during pluto startup. Failure of a self-test | |
1492 | currently issues a warning only but does not exit pluto [yet]. | |
1493 | ||
9b45443d MW |
1494 | - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2. |
1495 | ||
c5d0fbb6 | 1496 | - Full support of CA information sections. ipsec listcainfos |
b6b90b68 | 1497 | now shows all collected crlDistributionPoints and OCSP |
c5d0fbb6 AS |
1498 | accessLocations. |
1499 | ||
69ed04bf AS |
1500 | - Support of the Online Certificate Status Protocol (OCSP) for IKEv2. |
1501 | This feature requires the HTTP fetching capabilities of the libcurl | |
1502 | library which must be enabled by setting the --enable-http configure | |
1503 | option. | |
1504 | ||
9b45443d MW |
1505 | - Refactored core of the IKEv2 message processing code, allowing better |
1506 | code reuse and separation. | |
1507 | ||
1508 | - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration | |
1509 | payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted | |
1510 | by the requestor and installed in a resolv.conf file. | |
1511 | ||
1512 | - The IKEv2 daemon charon installs a route for each IPsec policy to use | |
1513 | the correct source address even if an application does not explicitly | |
1514 | specify it. | |
1515 | ||
1516 | - Integrated the EAP framework into charon which loads pluggable EAP library | |
1517 | modules. The ipsec.conf parameter authby=eap initiates EAP authentication | |
1518 | on the client side, while the "eap" parameter on the server side defines | |
1519 | the EAP method to use for client authentication. | |
1520 | A generic client side EAP-Identity module and an EAP-SIM authentication | |
1521 | module using a third party card reader implementation are included. | |
1522 | ||
1523 | - Added client side support for cookies. | |
1524 | ||
1525 | - Integrated the fixes done at the IKEv2 interoperability bakeoff, including | |
1526 | strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor | |
1527 | fixes to enhance interoperability with other implementations. | |

1c266d7d AS |
1530 | strongswan-4.0.7 |
1531 | ---------------- | |
1532 | ||
6fdf5f44 AS |
1533 | - strongSwan now interoperates with the NCP Secure Entry Client, |
1534 | the Shrew Soft VPN Client, and the Cisco VPN client, doing both | |
1535 | XAUTH and Mode Config. | |
1c266d7d AS |
1536 | |
1537 | - UNITY attributes are now recognized and UNITY_BANNER is set | |
1538 | to a default string. | |

2b4405a3 MW |
1541 | strongswan-4.0.6 |
1542 | ---------------- | |
1543 | ||
e38a15d4 AS |
1544 | - IKEv1: Support for extended authentication (XAUTH) in combination |
1545 | with ISAKMP Main Mode RSA or PSK authentication. Both client and | |
1546 | server side were implemented. Handling of user credentials can | |
1547 | be done by a run-time loadable XAUTH module. By default user | |
b6b90b68 MW |
1548 | credentials are stored in ipsec.secrets. |
1549 | ||
2b4405a3 MW |
1550 | - IKEv2: Support for reauthentication when rekeying |
1551 | ||
5903179b | 1552 | - IKEv2: Support for transport mode |
af87afed | 1553 | |
5903179b | 1554 | - fixed a lot of bugs related to byte order |
2b4405a3 | 1555 | |
5903179b | 1556 | - various other bugfixes |
2b4405a3 MW |
1557 | |

0cd645d2 AS |
1559 | strongswan-4.0.5 |
1560 | ---------------- | |
1561 | ||
1562 | - IKEv1: Implementation of ModeConfig push mode via the new connection | |
1563 | keyword modeconfig=push allows interoperability with Cisco VPN gateways. | |
1564 | ||
1565 | - IKEv1: The command ipsec statusall now shows "DPD active" for all | |
1566 | ISAKMP SAs that are under active Dead Peer Detection control. | |
1567 | ||
1568 | - IKEv2: Charon's logging and debugging framework has been completely rewritten. | |
1569 | Instead of logger, special printf() functions are used to directly | |
1570 | print objects like hosts (%H) identifications (%D), certificates (%Q), | |
1571 | etc. The number of debugging levels have been reduced to: | |
03bf883d | 1572 | |
0cd645d2 | 1573 | 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private) |
03bf883d | 1574 | |
0cd645d2 AS |
1575 | The debugging levels can either be specified statically in ipsec.conf as |
1576 | ||
1577 | config setup | |
03bf883d | 1578 | charondebug="lib 1, cfg 3, net 2" |
0cd645d2 | 1579 | |
03bf883d | 1580 | or changed at runtime via stroke as |
0cd645d2 | 1581 | |
03bf883d | 1582 | ipsec stroke loglevel cfg 2 |

48dc3934 MW |
1585 | strongswan-4.0.4 |
1586 | ---------------- | |
1587 | ||
1588 | - Implemented full support for IPv6-in-IPv6 tunnels. | |
1589 | ||
1590 | - Added configuration options for dead peer detection in IKEv2. dpd_action | |
1591 | types "clear", "hold" and "restart" are supported. The dpd_timeout | |
1592 | value is not used, as the normal retransmission policy applies to | |
1593 | detect dead peers. The dpd_delay parameter enables sending of empty | |
1594 | informational message to detect dead peers in case of inactivity. | |
1595 | ||
1596 | - Added support for preshared keys in IKEv2. PSK keys configured in | |
1597 | ipsec.secrets are loaded. The authby parameter specifies the authentication | |
1598 | method to authentificate ourself, the other peer may use PSK or RSA. | |
1599 | ||
1600 | - Changed retransmission policy to respect the keyingtries parameter. | |
1601 | ||
112ad7c3 AS |
1602 | - Added private key decryption. PEM keys encrypted with AES-128/192/256 |
1603 | or 3DES are supported. | |
48dc3934 MW |
1604 | |
1605 | - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to | |
1606 | encrypt IKE traffic. | |
1607 | ||
1608 | - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates | |
1609 | signed with such a hash algorithm. | |
1610 | ||
1611 | - Added initial support for updown scripts. The actions up-host/client and | |
1612 | down-host/client are executed. The leftfirewall=yes parameter | |
1613 | uses the default updown script to insert dynamic firewall rules, a custom | |
1614 | updown script may be specified with the leftupdown parameter. | |
1615 | ||
1616 | ||
a1310b6b MW |
1617 | strongswan-4.0.3 |
1618 | ---------------- | |
1619 | ||
1620 | - Added support for the auto=route ipsec.conf parameter and the | |
b6b90b68 MW |
1621 | ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and |
1622 | CHILD_SAs dynamically on demand when traffic is detected by the | |
a1310b6b MW |
1623 | kernel. |
1624 | ||
1625 | - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter. | |
1626 | As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only | |
1627 | new keys are generated using perfect forward secrecy. An optional flag | |
1628 | which enforces reauthentication will be implemented later. | |
1629 | ||
b425d998 AS |
1630 | - "sha" and "sha1" are now treated as synonyms in the ike= and esp= |
1631 | algorithm configuration statements. | |
1632 | ||
1633 | ||
bf4df11f AS |
1634 | strongswan-4.0.2 |
1635 | ---------------- | |
1636 | ||
623d3dcf AS |
1637 | - Full X.509 certificate trust chain verification has been implemented. |
1638 | End entity certificates can be exchanged via CERT payloads. The current | |
1639 | default is leftsendcert=always, since CERTREQ payloads are not supported | |
1640 | yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls. | |
efa40c11 | 1641 | |
b6b90b68 | 1642 | - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2 |
efa40c11 | 1643 | would offer more possibilities for traffic selection, but the Linux kernel |
b6b90b68 | 1644 | currently does not support it. That's why we stick with these simple |
efa40c11 MW |
1645 | ipsec.conf rules for now. |
1646 | ||
623d3dcf AS |
1647 | - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no |
1648 | IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear, | |
1649 | dpddelay=60s). | |
1650 | ||
efa40c11 MW |
1651 | - Initial NAT traversal support in IKEv2. Charon includes NAT detection |
1652 | notify payloads to detect NAT routers between the peers. It switches | |
1653 | to port 4500, uses UDP encapsulated ESP packets, handles peer address | |
1654 | changes gracefully and sends keep alive message periodically. | |
1655 | ||
b6b90b68 MW |
1656 | - Reimplemented IKE_SA state machine for charon, which allows simultaneous |
1657 | rekeying, more shared code, cleaner design, proper retransmission | |
efa40c11 MW |
1658 | and a more extensible code base. |
1659 | ||
cfd8b27f AS |
1660 | - The mixed PSK/RSA roadwarrior detection capability introduced by the |
1661 | strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal | |
1662 | payloads by the responder right before any defined IKE Main Mode state had | |
1663 | been established. Although any form of bad proposal syntax was being correctly | |
1664 | detected by the payload parser, the subsequent error handler didn't check | |
1665 | the state pointer before logging current state information, causing an | |
1666 | immediate crash of the pluto keying daemon due to a NULL pointer. | |
1667 | ||
bf4df11f | 1668 | |
7e81e975 MW |
1669 | strongswan-4.0.1 |
1670 | ---------------- | |
1671 | ||
b6b90b68 | 1672 | - Added algorithm selection to charon: New default algorithms for |
c15c3d4b MW |
1673 | ike=aes128-sha-modp2048, as both daemons support it. The default |
1674 | for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles | |
1675 | the ike/esp parameter the same way as pluto. As this syntax does | |
b6b90b68 | 1676 | not allow specification of a pseudo random function, the same |
c15c3d4b MW |
1677 | algorithm as for integrity is used (currently sha/md5). Supported |
1678 | algorithms for IKE: | |
1679 | Encryption: aes128, aes192, aes256 | |
1680 | Integrity/PRF: md5, sha (using hmac) | |
1681 | DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192 | |
1682 | and for ESP: | |
b6b90b68 | 1683 | Encryption: aes128, aes192, aes256, 3des, blowfish128, |
c15c3d4b MW |
1684 | blowfish192, blowfish256 |
1685 | Integrity: md5, sha1 | |
1686 | More IKE encryption algorithms will come after porting libcrypto into | |
b6b90b68 | 1687 | libstrongswan. |
f2c2d395 | 1688 | |
c15c3d4b MW |
1689 | - initial support for rekeying CHILD_SAs using IKEv2. Currently no |
1690 | perfect forward secrecy is used. The rekeying parameters rekey, | |
22ff6f57 | 1691 | rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported |
c15c3d4b MW |
1692 | when using IKEv2. WARNING: charon currently is unable to handle |
1693 | simultaneous rekeying. To avoid such a situation, use a large | |
1694 | rekeyfuzz, or even better, set rekey=no on one peer. | |
22ff6f57 | 1695 | |
7e81e975 MW |
1696 | - support for host2host, net2net, host2net (roadwarrior) tunnels |
1697 | using predefined RSA certificates (see uml scenarios for | |
1698 | configuration examples). | |
1699 | ||
f2c2d395 MW |
1700 | - new build environment featuring autotools. Features such |
1701 | as HTTP, LDAP and smartcard support may be enabled using | |
b6b90b68 | 1702 | the ./configure script. Changing install directories |
f2c2d395 MW |
1703 | is possible, too. See ./configure --help for more details. |
1704 | ||
22ff6f57 MW |
1705 | - better integration of charon with ipsec starter, which allows |
1706 | (almost) transparent operation with both daemons. charon | |
1707 | handles ipsec commands up, down, status, statusall, listall, | |
1708 | listcerts and allows proper load, reload and delete of connections | |
1709 | via ipsec starter. | |
1710 | ||
b425d998 | 1711 | |
9820c0e2 MW |
1712 | strongswan-4.0.0 |
1713 | ---------------- | |
1714 | ||
1715 | - initial support of the IKEv2 protocol. Connections in | |
b6b90b68 | 1716 | ipsec.conf designated by keyexchange=ikev2 are negotiated |
9820c0e2 MW |
1717 | by the new IKEv2 charon keying daemon whereas those marked |
1718 | by keyexchange=ikev1 or the default keyexchange=ike are | |
1719 | handled thy the IKEv1 pluto keying daemon. Currently only | |
1720 | a limited subset of functions are available with IKEv2 | |
1721 | (Default AES encryption, authentication based on locally | |
1722 | imported X.509 certificates, unencrypted private RSA keys | |
1723 | in PKCS#1 file format, limited functionality of the ipsec | |
1724 | status command). | |
1725 | ||
1726 | ||
997358a6 MW |
1727 | strongswan-2.7.0 |
1728 | ---------------- | |
1729 | ||
1730 | - the dynamic iptables rules from the _updown_x509 template | |
1731 | for KLIPS and the _updown_policy template for NETKEY have | |
1732 | been merged into the default _updown script. The existing | |
1733 | left|rightfirewall keyword causes the automatic insertion | |
1734 | and deletion of ACCEPT rules for tunneled traffic upon | |
1735 | the successful setup and teardown of an IPsec SA, respectively. | |
1736 | left|rightfirwall can be used with KLIPS under any Linux 2.4 | |
1737 | kernel or with NETKEY under a Linux kernel version >= 2.6.16 | |
f3bb1bd0 | 1738 | in conjunction with iptables >= 1.3.5. For NETKEY under a Linux |
997358a6 MW |
1739 | kernel version < 2.6.16 which does not support IPsec policy |
1740 | matching yet, please continue to use a copy of the _updown_espmark | |
1741 | template loaded via the left|rightupdown keyword. | |
1742 | ||
1743 | - a new left|righthostaccess keyword has been introduced which | |
1744 | can be used in conjunction with left|rightfirewall and the | |
1745 | default _updown script. By default leftfirewall=yes inserts | |
1746 | a bi-directional iptables FORWARD rule for a local client network | |
1747 | with a netmask different from 255.255.255.255 (single host). | |
1748 | This does not allow to access the VPN gateway host via its | |
1749 | internal network interface which is part of the client subnet | |
1750 | because an iptables INPUT and OUTPUT rule would be required. | |
1751 | lefthostaccess=yes will cause this additional ACCEPT rules to | |
b6b90b68 | 1752 | be inserted. |
997358a6 MW |
1753 | |
1754 | - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal | |
1755 | payload is preparsed in order to find out whether the roadwarrior | |
1756 | requests PSK or RSA so that a matching connection candidate can | |
1757 | be found. | |
1758 | ||
1759 | ||
1760 | strongswan-2.6.4 | |
1761 | ---------------- | |
1762 | ||
1763 | - the new _updown_policy template allows ipsec policy based | |
1764 | iptables firewall rules. Required are iptables version | |
1765 | >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes | |
b6b90b68 | 1766 | the _updown_espmark template, so that no INPUT mangle rules |
997358a6 MW |
1767 | are required any more. |
1768 | ||
1769 | - added support of DPD restart mode | |
1770 | ||
1771 | - ipsec starter now allows the use of wildcards in include | |
1772 | statements as e.g. in "include /etc/my_ipsec/*.conf". | |
1773 | Patch courtesy of Matthias Haas. | |
1774 | ||
1775 | - the Netscape OID 'employeeNumber' is now recognized and can be | |
1776 | used as a Relative Distinguished Name in certificates. | |
1777 | ||
1778 | ||
1779 | strongswan-2.6.3 | |
1780 | ---------------- | |
1781 | ||
b6b90b68 | 1782 | - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec |
997358a6 MW |
1783 | command and not of ipsec setup any more. |
1784 | ||
1785 | - ipsec starter now supports AH authentication in conjunction with | |
1786 | ESP encryption. AH authentication is configured in ipsec.conf | |
1787 | via the auth=ah parameter. | |
b6b90b68 | 1788 | |
997358a6 MW |
1789 | - The command ipsec scencrypt|scdecrypt <args> is now an alias for |
1790 | ipsec whack --scencrypt|scdecrypt <args>. | |
1791 | ||
1792 | - get_sa_info() now determines for the native netkey IPsec stack | |
1793 | the exact time of the last use of an active eroute. This information | |
1794 | is used by the Dead Peer Detection algorithm and is also displayed by | |
1795 | the ipsec status command. | |
b6b90b68 | 1796 | |
997358a6 MW |
1797 | |
1798 | strongswan-2.6.2 | |
1799 | ---------------- | |
1800 | ||
1801 | - running under the native Linux 2.6 IPsec stack, the function | |
1802 | get_sa_info() is called by ipsec auto --status to display the current | |
1803 | number of transmitted bytes per IPsec SA. | |
1804 | ||
1805 | - get_sa_info() is also used by the Dead Peer Detection process to detect | |
1806 | recent ESP activity. If ESP traffic was received from the peer within | |
1807 | the last dpd_delay interval then no R_Y_THERE notification must be sent. | |
1808 | ||
1809 | - strongSwan now supports the Relative Distinguished Name "unstructuredName" | |
1810 | in ID_DER_ASN1_DN identities. The following notations are possible: | |
1811 | ||
1812 | rightid="unstructuredName=John Doe" | |
1813 | rightid="UN=John Doe" | |
1814 | ||
1815 | - fixed a long-standing bug which caused PSK-based roadwarrior connections | |
1816 | to segfault in the function id.c:same_id() called by keys.c:get_secret() | |
1817 | if an FQDN, USER_FQDN, or Key ID was defined, as in the following example. | |
1818 | ||
1819 | conn rw | |
1820 | right=%any | |
1821 | rightid=@foo.bar | |
1822 | authby=secret | |
1823 | ||
1824 | - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall). | |
1825 | ||
1826 | - ipsec starter didn't set host_addr and client.addr ports in whack msg. | |
1827 | ||
1828 | - in order to guarantee backwards-compatibility with the script-based | |
1829 | auto function (e.g. auto --replace), the ipsec starter scripts stores | |
1830 | the defaultroute information in the temporary file /var/run/ipsec.info. | |
1831 | ||
1832 | - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH | |
1833 | Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config | |
1834 | servers. | |
1835 | ||
1836 | - the ipsec starter now also recognizes the parameters authby=never and | |
1837 | type=passthrough|pass|drop|reject. | |
1838 | ||
1839 | ||
1840 | strongswan-2.6.1 | |
1841 | ---------------- | |
1842 | ||
1843 | - ipsec starter now supports the also parameter which allows | |
1844 | a modular structure of the connection definitions. Thus | |
1845 | "ipsec start" is now ready to replace "ipsec setup". | |
1846 | ||
1847 | ||
1848 | strongswan-2.6.0 | |
1849 | ---------------- | |
1850 | ||
1851 | - Mathieu Lafon's popular ipsec starter tool has been added to the | |
1852 | strongSwan distribution. Many thanks go to Stephan Scholz from astaro | |
1853 | for his integration work. ipsec starter is a C program which is going | |
1854 | to replace the various shell and awk starter scripts (setup, _plutoload, | |
1855 | _plutostart, _realsetup, _startklips, _confread, and auto). Since | |
1856 | ipsec.conf is now parsed only once, the starting of multiple tunnels is | |
1857 | accelerated tremedously. | |
1858 | ||
1859 | - Added support of %defaultroute to the ipsec starter. If the IP address | |
b6b90b68 | 1860 | changes, a HUP signal to the ipsec starter will automatically |
997358a6 MW |
1861 | reload pluto's connections. |
1862 | ||
1863 | - moved most compile time configurations from pluto/Makefile to | |
1864 | Makefile.inc by defining the options USE_LIBCURL, USE_LDAP, | |
1865 | USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE. | |
1866 | ||
1867 | - removed the ipsec verify and ipsec newhostkey commands | |
1868 | ||
1869 | - fixed some 64-bit issues in formatted print statements | |
1870 | ||
1871 | - The scepclient functionality implementing the Simple Certificate | |
1872 | Enrollment Protocol (SCEP) is nearly complete but hasn't been | |
1873 | documented yet. | |
1874 | ||
1875 | ||
1876 | strongswan-2.5.7 | |
1877 | ---------------- | |
1878 | ||
1879 | - CA certicates are now automatically loaded from a smartcard | |
1880 | or USB crypto token and appear in the ipsec auto --listcacerts | |
1881 | listing. | |
1882 | ||
1883 | ||
1884 | strongswan-2.5.6 | |
1885 | ---------------- | |
1886 | ||
1887 | - when using "ipsec whack --scencrypt <data>" with a PKCS#11 | |
1888 | library that does not support the C_Encrypt() Cryptoki | |
1889 | function (e.g. OpenSC), the RSA encryption is done in | |
1890 | software using the public key fetched from the smartcard. | |
1891 | ||
b6b90b68 | 1892 | - The scepclient function now allows to define the |
997358a6 MW |
1893 | validity of a self-signed certificate using the --days, |
1894 | --startdate, and --enddate options. The default validity | |
1895 | has been changed from one year to five years. | |
1896 | ||
1897 | ||
1898 | strongswan-2.5.5 | |
1899 | ---------------- | |
1900 | ||
1901 | - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11 | |
1902 | interface to other applications for RSA encryption and decryption | |
1903 | via the whack interface. Notation: | |
1904 | ||
1905 | ipsec whack --scencrypt <data> | |
1906 | [--inbase 16|hex|64|base64|256|text|ascii] | |
1907 | [--outbase 16|hex|64|base64|256|text|ascii] | |
1908 | [--keyid <keyid>] | |
1909 | ||
1910 | ipsec whack --scdecrypt <data> | |
1911 | [--inbase 16|hex|64|base64|256|text|ascii] | |
1912 | [--outbase 16|hex|64|base64|256|text|ascii] | |
1913 | [--keyid <keyid>] | |
1914 | ||
b6b90b68 | 1915 | The default setting for inbase and outbase is hex. |
997358a6 MW |
1916 | |
1917 | The new proxy interface can be used for securing symmetric | |
1918 | encryption keys required by the cryptoloop or dm-crypt | |
1919 | disk encryption schemes, especially in the case when | |
1920 | pkcs11keepstate=yes causes pluto to lock the pkcs11 slot | |
1921 | permanently. | |
1922 | ||
1923 | - if the file /etc/ipsec.secrets is lacking during the startup of | |
1924 | pluto then the root-readable file /etc/ipsec.d/private/myKey.der | |
1925 | containing a 2048 bit RSA private key and a matching self-signed | |
1926 | certificate stored in the file /etc/ipsec.d/certs/selfCert.der | |
1927 | is automatically generated by calling the function | |
1928 | ||
1929 | ipsec scepclient --out pkcs1 --out cert-self | |
1930 | ||
1931 | scepclient was written by Jan Hutter and Martin Willi, students | |
1932 | at the University of Applied Sciences in Rapperswil, Switzerland. | |
1933 | ||
1934 | ||
1935 | strongswan-2.5.4 | |
1936 | ---------------- | |
1937 | ||
1938 | - the current extension of the PKCS#7 framework introduced | |
1939 | a parsing error in PKCS#7 wrapped X.509 certificates that are | |
1940 | e.g. transmitted by Windows XP when multi-level CAs are used. | |
1941 | the parsing syntax has been fixed. | |
1942 | ||
1943 | - added a patch by Gerald Richter which tolerates multiple occurrences | |
1944 | of the ipsec0 interface when using KLIPS. | |
1945 | ||
1946 | ||
1947 | strongswan-2.5.3 | |
1948 | ---------------- | |
1949 | ||
1950 | - with gawk-3.1.4 the word "default2 has become a protected | |
1951 | keyword for use in switch statements and cannot be used any | |
1952 | more in the strongSwan scripts. This problem has been | |
1953 | solved by renaming "default" to "defaults" and "setdefault" | |
1954 | in the scripts _confread and auto, respectively. | |
1955 | ||
1956 | - introduced the parameter leftsendcert with the values | |
1957 | ||
1958 | always|yes (the default, always send a cert) | |
1959 | ifasked (send the cert only upon a cert request) | |
1960 | never|no (never send a cert, used for raw RSA keys and | |
b6b90b68 | 1961 | self-signed certs) |
997358a6 MW |
1962 | |
1963 | - fixed the initialization of the ESP key length to a default of | |
1964 | 128 bits in the case that the peer does not send a key length | |
1965 | attribute for AES encryption. | |
1966 | ||
1967 | - applied Herbert Xu's uniqueIDs patch | |
1968 | ||
1969 | - applied Herbert Xu's CLOEXEC patches | |
1970 | ||
1971 | ||
1972 | strongswan-2.5.2 | |
1973 | ---------------- | |
1974 | ||
1975 | - CRLs can now be cached also in the case when the issuer's | |
1976 | certificate does not contain a subjectKeyIdentifier field. | |
1977 | In that case the subjectKeyIdentifier is computed by pluto as the | |
1978 | 160 bit SHA-1 hash of the issuer's public key in compliance | |
1979 | with section 4.2.1.2 of RFC 3280. | |
1980 | ||
1981 | - Fixed a bug introduced by strongswan-2.5.1 which eliminated | |
1982 | not only multiple Quick Modes of a given connection but also | |
1983 | multiple connections between two security gateways. | |
1984 | ||
1985 | ||
1986 | strongswan-2.5.1 | |
1987 | ---------------- | |
1988 | ||
1989 | - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute | |
1990 | installed either by setting auto=route in ipsec.conf or by | |
1991 | a connection put into hold, generates an XFRM_AQUIRE event | |
1992 | for each packet that wants to use the not-yet exisiting | |
1993 | tunnel. Up to now each XFRM_AQUIRE event led to an entry in | |
1994 | the Quick Mode queue, causing multiple IPsec SA to be | |
1995 | established in rapid succession. Starting with strongswan-2.5.1 | |
1996 | only a single IPsec SA is established per host-pair connection. | |
1997 | ||
1998 | - Right after loading the PKCS#11 module, all smartcard slots are | |
1999 | searched for certificates. The result can be viewed using | |
2000 | the command | |
2001 | ||
2002 | ipsec auto --listcards | |
2003 | ||
2004 | The certificate objects found in the slots are numbered | |
2005 | starting with #1, #2, etc. This position number can be used to address | |
2006 | certificates (leftcert=%smartcard) and keys (: PIN %smartcard) | |
2007 | in ipsec.conf and ipsec.secrets, respectively: | |
2008 | ||
2009 | %smartcard (selects object #1) | |
2010 | %smartcard#1 (selects object #1) | |
2011 | %smartcard#3 (selects object #3) | |
2012 | ||
2013 | As an alternative the existing retrieval scheme can be used: | |
2014 | ||
2015 | %smartcard:45 (selects object with id=45) | |
2016 | %smartcard0 (selects first object in slot 0) | |
2017 | %smartcard4:45 (selects object in slot 4 with id=45) | |
2018 | ||
2019 | - Depending on the settings of CKA_SIGN and CKA_DECRYPT | |
2020 | private key flags either C_Sign() or C_Decrypt() is used | |
2021 | to generate a signature. | |
2022 | ||
2023 | - The output buffer length parameter siglen in C_Sign() | |
2024 | is now initialized to the actual size of the output | |
2025 | buffer prior to the function call. This fixes the | |
2026 | CKR_BUFFER_TOO_SMALL error that could occur when using | |
2027 | the OpenSC PKCS#11 module. | |
2028 | ||
2029 | - Changed the initialization of the PKCS#11 CK_MECHANISM in | |
2030 | C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }. | |
2031 | ||
2032 | - Refactored the RSA public/private key code and transferred it | |
2033 | from keys.c to the new pkcs1.c file as a preparatory step | |
2034 | towards the release of the SCEP client. | |
2035 | ||
2036 | ||
2037 | strongswan-2.5.0 | |
2038 | ---------------- | |
2039 | ||
2040 | - The loading of a PKCS#11 smartcard library module during | |
2041 | runtime does not require OpenSC library functions any more | |
2042 | because the corresponding code has been integrated into | |
2043 | smartcard.c. Also the RSAREF pkcs11 header files have been | |
2044 | included in a newly created pluto/rsaref directory so that | |
2045 | no external include path has to be defined any longer. | |
2046 | ||
2047 | - A long-awaited feature has been implemented at last: | |
2048 | The local caching of CRLs fetched via HTTP or LDAP, activated | |
2049 | by the parameter cachecrls=yes in the config setup section | |
2050 | of ipsec.conf. The dynamically fetched CRLs are stored under | |
2051 | a unique file name containing the issuer's subjectKeyID | |
2052 | in /etc/ipsec.d/crls. | |
b6b90b68 | 2053 | |
997358a6 MW |
2054 | - Applied a one-line patch courtesy of Michael Richardson |
2055 | from the Openswan project which fixes the kernel-oops | |
2056 | in KLIPS when an snmp daemon is running on the same box. | |
2057 | ||
2058 | ||
2059 | strongswan-2.4.4 | |
2060 | ---------------- | |
2061 | ||
2062 | - Eliminated null length CRL distribution point strings. | |
2063 | ||
2064 | - Fixed a trust path evaluation bug introduced with 2.4.3 | |
2065 | ||
2066 | ||
2067 | strongswan-2.4.3 | |
2068 | ---------------- | |
2069 | ||
2070 | - Improved the joint OCSP / CRL revocation policy. | |
2071 | OCSP responses have precedence over CRL entries. | |
2072 | ||
2073 | - Introduced support of CRLv2 reason codes. | |
2074 | ||
2075 | - Fixed a bug with key-pad equipped readers which caused | |
2076 | pluto to prompt for the pin via the console when the first | |
2077 | occasion to enter the pin via the key-pad was missed. | |
2078 | ||
2079 | - When pluto is built with LDAP_V3 enabled, the library | |
2080 | liblber required by newer versions of openldap is now | |
2081 | included. | |
2082 | ||
2083 | ||
2084 | strongswan-2.4.2 | |
2085 | ---------------- | |
2086 | ||
2087 | - Added the _updown_espmark template which requires all | |
2088 | incoming ESP traffic to be marked with a default mark | |
2089 | value of 50. | |
b6b90b68 | 2090 | |
997358a6 MW |
2091 | - Introduced the pkcs11keepstate parameter in the config setup |
2092 | section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11 | |
b6b90b68 | 2093 | session and login states are kept as long as possible during |
997358a6 MW |
2094 | the lifetime of pluto. This means that a PIN entry via a key |
2095 | pad has to be done only once. | |
2096 | ||
2097 | - Introduced the pkcs11module parameter in the config setup | |
2098 | section of ipsec.conf which specifies the PKCS#11 module | |
2099 | to be used with smart cards. Example: | |
b6b90b68 | 2100 | |
997358a6 | 2101 | pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo |
b6b90b68 | 2102 | |
997358a6 MW |
2103 | - Added support of smartcard readers equipped with a PIN pad. |
2104 | ||
2105 | - Added patch by Jay Pfeifer which detects when netkey | |
2106 | modules have been statically built into the Linux 2.6 kernel. | |
2107 | ||
2108 | - Added two patches by Herbert Xu. The first uses ip xfrm | |
2109 | instead of setkey to flush the IPsec policy database. The | |
2110 | second sets the optional flag in inbound IPComp SAs only. | |
b6b90b68 | 2111 | |
997358a6 MW |
2112 | - Applied Ulrich Weber's patch which fixes an interoperability |
2113 | problem between native IPsec and KLIPS systems caused by | |
2114 | setting the replay window to 32 instead of 0 for ipcomp. | |
2115 | ||
2116 | ||
2117 | strongswan-2.4.1 | |
2118 | ---------------- | |
2119 | ||
2120 | - Fixed a bug which caused an unwanted Mode Config request | |
2121 | to be initiated in the case where "right" was used to denote | |
2122 | the local side in ipsec.conf and "left" the remote side, | |
2123 | contrary to the recommendation that "right" be remote and | |
2124 | "left" be"local". | |
2125 | ||
2126 | ||
2127 | strongswan-2.4.0a | |
2128 | ----------------- | |
2129 | ||
2130 | - updated Vendor ID to strongSwan-2.4.0 | |
2131 | ||
2132 | - updated copyright statement to include David Buechi and | |
2133 | Michael Meier | |
b6b90b68 MW |
2134 | |
2135 | ||
997358a6 MW |
2136 | strongswan-2.4.0 |
2137 | ---------------- | |
2138 | ||
2139 | - strongSwan now communicates with attached smartcards and | |
2140 | USB crypto tokens via the standardized PKCS #11 interface. | |
2141 | By default the OpenSC library from www.opensc.org is used | |
2142 | but any other PKCS#11 library could be dynamically linked. | |
2143 | strongSwan's PKCS#11 API was implemented by David Buechi | |
2144 | and Michael Meier, both graduates of the Zurich University | |
2145 | of Applied Sciences in Winterthur, Switzerland. | |
2146 | ||
2147 | - When a %trap eroute is triggered by an outgoing IP packet | |
2148 | then the native IPsec stack of the Linux 2.6 kernel [often/ | |
2149 | always?] returns an XFRM_ACQUIRE message with an undefined | |
2150 | protocol family field and the connection setup fails. | |
2151 | As a workaround IPv4 (AF_INET) is now assumed. | |
b6b90b68 MW |
2152 | |
2153 | - the results of the UML test scenarios are now enhanced | |
997358a6 | 2154 | with block diagrams of the virtual network topology used |
b6b90b68 | 2155 | in a particular test. |
997358a6 MW |
2156 | |
2157 | ||
2158 | strongswan-2.3.2 | |
2159 | ---------------- | |
2160 | ||
2161 | - fixed IV used to decrypt informational messages. | |
2162 | This bug was introduced with Mode Config functionality. | |
b6b90b68 | 2163 | |
997358a6 MW |
2164 | - fixed NCP Vendor ID. |
2165 | ||
2166 | - undid one of Ulrich Weber's maximum udp size patches | |
2167 | because it caused a segmentation fault with NAT-ed | |
2168 | Delete SA messages. | |
b6b90b68 | 2169 | |
997358a6 MW |
2170 | - added UML scenarios wildcards and attr-cert which |
2171 | demonstrate the implementation of IPsec policies based | |
2172 | on wildcard parameters contained in Distinguished Names and | |
2173 | on X.509 attribute certificates, respectively. | |
2174 | ||
2175 | ||
2176 | strongswan-2.3.1 | |
2177 | ---------------- | |
2178 | ||
2179 | - Added basic Mode Config functionality | |
2180 | ||
2181 | - Added Mathieu Lafon's patch which upgrades the status of | |
2182 | the NAT-Traversal implementation to RFC 3947. | |
b6b90b68 | 2183 | |
997358a6 MW |
2184 | - The _startklips script now also loads the xfrm4_tunnel |
2185 | module. | |
b6b90b68 | 2186 | |
997358a6 MW |
2187 | - Added Ulrich Weber's netlink replay window size and |
2188 | maximum udp size patches. | |
2189 | ||
2190 | - UML testing now uses the Linux 2.6.10 UML kernel by default. | |
b6b90b68 | 2191 | |
997358a6 MW |
2192 | |
2193 | strongswan-2.3.0 | |
2194 | ---------------- | |
2195 | ||
2196 | - Eric Marchionni and Patrik Rayo, both recent graduates from | |
2197 | the Zuercher Hochschule Winterthur in Switzerland, created a | |
2198 | User-Mode-Linux test setup for strongSwan. For more details | |
2199 | please read the INSTALL and README documents in the testing | |
2200 | subdirectory. | |
2201 | ||
2202 | - Full support of group attributes based on X.509 attribute | |
b6b90b68 | 2203 | certificates. Attribute certificates can be generated |
997358a6 | 2204 | using the openac facility. For more details see |
b6b90b68 | 2205 | |
997358a6 | 2206 | man ipsec_openac. |
b6b90b68 | 2207 | |
997358a6 MW |
2208 | The group attributes can be used in connection definitions |
2209 | in order to give IPsec access to specific user groups. | |
2210 | This is done with the new parameter left|rightgroups as in | |
b6b90b68 | 2211 | |
997358a6 MW |
2212 | rightgroups="Research, Sales" |
2213 | ||
2214 | giving access to users possessing the group attributes | |
2215 | Research or Sales, only. | |
2216 | ||
2217 | - In Quick Mode clients with subnet mask /32 are now | |
b6b90b68 | 2218 | coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should |
997358a6 MW |
2219 | fix rekeying problems with the SafeNet/SoftRemote and NCP |
2220 | Secure Entry Clients. | |
2221 | ||
2222 | - Changed the defaults of the ikelifetime and keylife parameters | |
2223 | to 3h and 1h, respectively. The maximum allowable values are | |
2224 | now both set to 24 h. | |
2225 | ||
2226 | - Suppressed notification wars between two IPsec peers that | |
2227 | could e.g. be triggered by incorrect ISAKMP encryption. | |
2228 | ||
2229 | - Public RSA keys can now have identical IDs if either the | |
2230 | issuing CA or the serial number is different. The serial | |
2231 | number of a certificate is now shown by the command | |
b6b90b68 | 2232 | |
997358a6 MW |
2233 | ipsec auto --listpubkeys |
2234 | ||
2235 | ||
2236 | strongswan-2.2.2 | |
2237 | ---------------- | |
2238 | ||
2239 | - Added Tuomo Soini's sourceip feature which allows a strongSwan | |
2240 | roadwarrior to use a fixed Virtual IP (see README section 2.6) | |
2241 | and reduces the well-known four tunnel case on VPN gateways to | |
2242 | a single tunnel definition (see README section 2.4). | |
2243 | ||
f3bb1bd0 | 2244 | - Fixed a bug occurring with NAT-Traversal enabled when the responder |
997358a6 MW |
2245 | suddenly turns initiator and the initiator cannot find a matching |
2246 | connection because of the floated IKE port 4500. | |
b6b90b68 | 2247 | |
997358a6 MW |
2248 | - Removed misleading ipsec verify command from barf. |
2249 | ||
2250 | - Running under the native IP stack, ipsec --version now shows | |
2251 | the Linux kernel version (courtesy to the Openswan project). | |
2252 | ||
2253 | ||
2254 | strongswan-2.2.1 | |
2255 | ---------------- | |
2256 | ||
2257 | - Introduced the ipsec auto --listalgs monitoring command which lists | |
2258 | all currently registered IKE and ESP algorithms. | |
2259 | ||
f3bb1bd0 | 2260 | - Fixed a bug in the ESP algorithm selection occurring when the strict flag |
997358a6 | 2261 | is set and the first proposed transform does not match. |
b6b90b68 | 2262 | |
997358a6 | 2263 | - Fixed another deadlock in the use of the lock_certs_and_keys() mutex, |
f3bb1bd0 | 2264 | occurring when a smartcard is present. |
997358a6 MW |
2265 | |
2266 | - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event. | |
b6b90b68 | 2267 | |
997358a6 MW |
2268 | - Fixed the printing of the notification names (null) |
2269 | ||
2270 | - Applied another of Herbert Xu's Netlink patches. | |
2271 | ||
2272 | ||
2273 | strongswan-2.2.0 | |
2274 | ---------------- | |
2275 | ||
2276 | - Support of Dead Peer Detection. The connection parameter | |
2277 | ||
2278 | dpdaction=clear|hold | |
b6b90b68 | 2279 | |
997358a6 MW |
2280 | activates DPD for the given connection. |
2281 | ||
2282 | - The default Opportunistic Encryption (OE) policy groups are not | |
2283 | automatically included anymore. Those wishing to activate OE can include | |
2284 | the policy group with the following statement in ipsec.conf: | |
b6b90b68 | 2285 | |
997358a6 | 2286 | include /etc/ipsec.d/examples/oe.conf |
b6b90b68 | 2287 | |
997358a6 MW |
2288 | The default for [right|left]rsasigkey is now set to %cert. |
2289 | ||
2290 | - strongSwan now has a Vendor ID of its own which can be activated | |
2291 | using the compile option VENDORID | |
2292 | ||
2293 | - Applied Herbert Xu's patch which sets the compression algorithm correctly. | |
2294 | ||
2295 | - Applied Herbert Xu's patch fixing an ESPINUDP problem | |
2296 | ||
2297 | - Applied Herbert Xu's patch setting source/destination port numbers. | |
2298 | ||
2299 | - Reapplied one of Herbert Xu's NAT-Traversal patches which got | |
2300 | lost during the migration from SuperFreeS/WAN. | |

2302 | - Fixed a deadlock in the use of the lock_certs_and_keys() mutex. |
2303 | ||
2304 | - Fixed the unsharing of alg parameters when instantiating group | |
2305 | connection. | |

2309 | ---------------- | |
2310 | ||
2311 | - Thomas Walpuski made me aware of a potential DoS attack via | |
2312 | a PKCS#7-wrapped certificate bundle which could overwrite valid CA | |
2313 | certificates in Pluto's authority certificate store. This vulnerability | |
2314 | was fixed by establishing trust in CA candidate certificates up to a | |
2315 | trusted root CA prior to insertion into Pluto's chained list. | |
2316 | ||
2317 | - replaced the --assign option by the -v option in the auto awk script | |
2318 | in order to make it run with mawk under debian/woody. | |
2319 | ||
2320 | ||
2321 | strongswan-2.1.4 | |
2322 | ---------------- | |
2323 | ||
2324 | - Split of the status information between ipsec auto --status (concise) | |
2325 | and ipsec auto --statusall (verbose). Both commands can be used with | |
2326 | an optional connection selector: | |
2327 | ||
2328 | ipsec auto --status[all] <connection_name> | |
2329 | ||
2330 | - Added the description of X.509 related features to the ipsec_auto(8) | |
2331 | man page. | |
2332 | ||
2333 | - Hardened the ASN.1 parser in debug mode, especially the printing | |
2334 | of malformed distinguished names. | |
2335 | ||
2336 | - The size of an RSA public key received in a certificate is now restricted to | |
2337 | ||
2338 | 512 bits <= modulus length <= 8192 bits. | |
2339 | ||
2340 | - Fixed the debug mode enumeration. | |
2341 | ||
2342 | ||
2343 | strongswan-2.1.3 | |
2344 | ---------------- | |
2345 | ||
2346 | - Fixed another PKCS#7 vulnerability which could lead to an | |
2347 | endless loop while following the X.509 trust chain. | |

2349 | |
2350 | strongswan-2.1.2 | |
2351 | ---------------- | |
2352 | ||
2353 | - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski | |
2354 | that accepted end certificates having identical issuer and subject | |
2355 | distinguished names in a multi-tier X.509 trust chain. | |

2357 | |
2358 | strongswan-2.1.1 | |
2359 | ---------------- | |
2360 | ||
2361 | - Removed all remaining references to ipsec_netlink.h in KLIPS. | |
2362 | ||
2363 | ||
2364 | strongswan-2.1.0 | |
2365 | ---------------- | |
2366 | ||
2367 | - The new "ca" section allows to define the following parameters: | |
2368 | ||
2369 | ca kool | |
2370 | cacert=koolCA.pem # cacert of kool CA | |
2371 | ocspuri=http://ocsp.kool.net:8001 # ocsp server | |
2372 | ldapserver=ldap.kool.net # default ldap server | |
2373 | crluri=http://www.kool.net/kool.crl # crl distribution point | |
2374 | crluri2="ldap:///O=Kool, C= .." # crl distribution point #2 | |
2375 | auto=add # add, ignore | |
b6b90b68 | 2376 | |
997358a6 | 2377 | The ca definitions can be monitored via the command |

2380 | ||
2381 | - Fixed cosmetic corruption of /proc filesystem by integrating | |
2382 | D. Hugh Redelmeier's freeswan-2.06 kernel fixes. | |
2383 | ||
2384 | ||
2385 | strongswan-2.0.2 | |
2386 | ---------------- | |
2387 | ||
2388 | - Added support for the 818043 NAT-Traversal update of Microsoft's | |
2389 | Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode. | |

2390 | |
2391 | - A symbolic link to libcrypto is now added in the kernel sources | |
997358a6 | 2392 | during kernel compilation |

2394 | - Fixed a couple of 64 bit issues (mostly casts to int). |
2395 | Thanks to Ken Bantoft who checked my sources on a 64 bit platform. | |
2396 | ||
2397 | - Replaced s[n]printf() statements in the kernel by ipsec_snprintf(). | |
2398 | Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro | |
2399 | of the FreeS/WAN team who solved this problem with the 2.4.25 kernel. | |

2401 | ||
2402 | strongswan-2.0.1 | |
2403 | ---------------- | |
2404 | ||
2405 | - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName | |
2406 | certificate extension which contains no generalName item) can cause | |
2407 | a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has | |
2408 | been hardened to make it more robust against malformed ASN.1 objects. | |
2409 | ||
2410 | - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native | |
2411 | Linux 2.6 IPsec stack. | |
