1 | strongswan-4.3.1 |
2 | ---------------- | |
3 | ||
4 | - The nm plugin now passes DNS/NBNS server information to NetworkManager, | |
09dbca9f | 5 | allowing a gateway administrator to set DNS/NBNS configuration on clients |
3bf7c249 MW |
6 | dynamically. |
7 | ||
09dbca9f MW |
8 | - The nm plugin also accepts CA certificates for gateway authentication. If |
9 | a CA certificate is configured, strongSwan uses the entered gateway address | |
10 | as its idenitity, requiring the gateways certificate to contain the same as | |
11 | subjectAltName. This allows a gateway administrator to deploy the same | |
12 | certificates to Windows 7 and NetworkManager clients. | |

14 | - The command ipsec purgeike deletes IKEv2 SAs that don't have a CHILD SA. |
15 | The command ipsec down <conn>{n} deletes CHILD SA instance n of connection | |
16 | <conn> whereas ipsec down <conn>{*} deletes all CHILD SA instances. | |
17 | The command ipsec down <conn>[n] deletes IKE SA instance n of connection | |
18 | <conn> plus dependent CHILD SAs whereas ipsec down <conn>[*] deletes all | |
19 | IKE SA instances of connection <conn>. | |
20 | ||
09dbca9f | 21 | - Fixed a regression introduced in 4.3.0 where EAP authentication calculated |
047b2e42 MW |
22 | the AUTH payload incorrectly. Further, the EAP-MSCHAPv2 MSK key derivation |
23 | has been updated to be compatible with the Windows 7 Release Candidate. | |
24 | ||
25 | - Refactored installation of triggering policies. Routed policies are handled | |
26 | outside of IKE_SAs to keep them installed in any case. A tunnel gets | |
27 | established only once, even if initiation is delayed due network outages. | |
28 | ||
050cc582 AS |
29 | - Improved the handling of multiple acquire signals triggered by the kernel. |
30 | ||
31 | - Fixed two DoS vulnerabilities in the charon daemon that were discovered by | |
32 | fuzzing techniques: 1) Sending a malformed IKE_SA_INIT request leaved an | |
33 | incomplete state which caused a null pointer dereference if a subsequent | |
34 | CREATE_CHILD_SA request was sent. 2) Sending an IKE_AUTH request with either | |
35 | a missing TSi or TSr payload caused a null pointer derefence because the | |
36 | checks for TSi and TSr were interchanged. The IKEv2 fuzzer used was | |
37 | developped by the Orange Labs vulnerability research team. The tool was | |
38 | initially written by Gabriel Campana and is now maintained by Laurent Butti. | |
39 | ||
047b2e42 MW |
40 | - Added support for AES counter mode in ESP in IKEv2 using the proposal |
41 | keywords aes128ctr, aes192ctr and aes256ctr. | |
42 | ||
d44fd821 | 43 | - Further progress in refactoring pluto: Use of the curl and ldap plugins |
050cc582 AS |
44 | for fetching crls and OCSP. Use of the random plugin to get keying material |
45 | from /dev/random or /dev/urandom. Use of the openssl plugin as an alternative | |
d44fd821 | 46 | to the aes, des, sha1, sha2, and md5 plugins. The blowfish, twofish, and |
050cc582 | 47 | serpent encryption plugins are now optional and are not enabled by default. |

50 | strongswan-4.3.0 |
51 | ---------------- | |
52 | ||
81fc8e5f MW |
53 | - Support for the IKEv2 Multiple Authentication Exchanges extension (RFC4739). |
54 | Initiators and responders can use several authentication rounds (e.g. RSA | |
55 | followed by EAP) to authenticate. The new ipsec.conf leftauth/rightauth and | |
56 | leftauth2/rightauth2 parameters define own authentication rounds or setup | |
57 | constraints for the remote peer. See the ipsec.conf man page for more detials. | |
58 | ||
59 | - If glibc printf hooks (register_printf_function) are not available, | |
60 | strongSwan can use the vstr string library to run on non-glibc systems. | |
61 | ||
558c89e7 AS |
62 | - The IKEv2 charon daemon can now configure the ESP CAMELLIA-CBC cipher |
63 | (esp=camellia128|192|256). | |
247e665a | 64 | |
558c89e7 AS |
65 | - Refactored the pluto and scepclient code to use basic functions (memory |
66 | allocation, leak detective, chunk handling, printf_hooks, strongswan.conf | |
67 | attributes, ASN.1 parser, etc.) from the libstrongswan library. | |
b752f873 | 68 | |
558c89e7 AS |
69 | - Up to two DNS and WINS servers to be sent via IKEv1 ModeConfig can be |
70 | configured in the pluto section of strongswan.conf. | |

74 | ----------------- | |
75 | ||
22180558 AS |
76 | - The new server-side EAP RADIUS plugin (--enable-eap-radius) |
77 | relays EAP messages to and from a RADIUS server. Succesfully | |
78 | tested with with a freeradius server using EAP-MD5 and EAP-SIM. | |
79 | ||
79b27294 AS |
80 | - A vulnerability in the Dead Peer Detection (RFC 3706) code was found by |
81 | Gerd v. Egidy <gerd.von.egidy@intra2net.com> of Intra2net AG affecting | |
82 | all Openswan and strongSwan releases. A malicious (or expired ISAKMP) | |
83 | R_U_THERE or R_U_THERE_ACK Dead Peer Detection packet can cause the | |
84 | pluto IKE daemon to crash and restart. No authentication or encryption | |
85 | is required to trigger this bug. One spoofed UDP packet can cause the | |
86 | pluto IKE daemon to restart and be unresponsive for a few seconds while | |
87 | restarting. This DPD null state vulnerability has been officially | |
88 | registered as CVE-2009-0790 and is fixed by this release. | |
89 | ||
22180558 AS |
90 | - ASN.1 to time_t conversion caused a time wrap-around for |
91 | dates after Jan 18 03:14:07 UTC 2038 on 32-bit platforms. | |
92 | As a workaround such dates are set to the maximum representable | |
93 | time, i.e. Jan 19 03:14:07 UTC 2038. | |
94 | ||
95 | - Distinguished Names containing wildcards (*) are not sent in the | |
96 | IDr payload anymore. | |

98 | ||
076e7853 AS |
99 | strongswan-4.2.13 |
100 | ----------------- | |
101 | ||
102 | - Fixed a use-after-free bug in the DPD timeout section of the | |
103 | IKEv1 pluto daemon which sporadically caused a segfault. | |
104 | ||
105 | - Fixed a crash in the IKEv2 charon daemon occuring with | |
106 | mixed RAM-based and SQL-based virtual IP address pools. | |
107 | ||
f15483ef AS |
108 | - Fixed ASN.1 parsing of algorithmIdentifier objects where the |
109 | parameters field is optional. | |
110 | ||
03991bc1 MW |
111 | - Ported nm plugin to NetworkManager 7.1. |
112 | ||
076e7853 | 113 | |
bfde75ee | 114 | strongswan-4.2.12 |
076e7853 | 115 | ----------------- |
bfde75ee AS |
116 | |
117 | - Support of the EAP-MSCHAPv2 protocol enabled by the option | |
118 | --enable-eap-mschapv2. Requires the MD4 hash algorithm enabled | |
119 | either by --enable-md4 or --enable-openssl. | |
120 | ||
121 | - Assignment of up to two DNS and up to two WINS servers to peers via | |
122 | the IKEv2 Configuration Payload (CP). The IPv4 or IPv6 nameserver | |
123 | addresses are defined in strongswan.conf. | |
124 | ||
125 | - The strongSwan applet for the Gnome NetworkManager is now built and | |
126 | distributed as a separate tarball under the name NetworkManager-strongswan. | |
127 | ||
128 | ||
0519ca90 AS |
129 | strongswan-4.2.11 |
130 | ----------------- | |
131 | ||
ae1ae574 AS |
132 | - Fixed ESP NULL encryption broken by the refactoring of keymat.c. |
133 | Also introduced proper initialization and disposal of keying material. | |
134 | ||
135 | - Fixed the missing listing of connection definitions in ipsec statusall | |
136 | broken by an unfortunate local variable overload. | |
0519ca90 AS |
137 | |
138 | ||
4856241c MW |
139 | strongswan-4.2.10 |
140 | ----------------- | |
141 | ||
142 | - Several performance improvements to handle thousands of tunnels with almost | |
143 | linear upscaling. All relevant data structures have been replaced by faster | |
144 | counterparts with better lookup times. | |
145 | ||
146 | - Better parallelization to run charon on multiple cores. Due to improved | |
147 | ressource locking and other optimizations the daemon can take full | |
148 | advantage of 16 or even more cores. | |
149 | ||
150 | - The load-tester plugin can use a NULL Diffie-Hellman group and simulate | |
151 | unique identities and certificates by signing peer certificates using a CA | |
152 | on the fly. | |
153 | ||
154 | - The redesigned stroke in-memory IP pool handles leases. The "ipsec leases" | |
155 | command queries assigned leases. | |
156 | ||
157 | - Added support for smartcards in charon by using the ENGINE API provided by | |
158 | OpenSSL, based on patches by Michael Roßberg. | |
159 | ||
160 | - The Padlock plugin supports the hardware RNG found on VIA CPUs to provide a | |
161 | reliable source of randomness. | |
162 | ||
73937bd8 MW |
163 | strongswan-4.2.9 |
164 | ---------------- | |
165 | ||
509e07c5 AS |
166 | - Flexible configuration of logging subsystem allowing to log to multiple |
167 | syslog facilities or to files using fine-grained log levels for each target. | |
73937bd8 MW |
168 | |
169 | - Load testing plugin to do stress testing of the IKEv2 daemon against self | |
170 | or another host. Found and fixed issues during tests in the multi-threaded | |
171 | use of the OpenSSL plugin. | |
172 | ||
173 | - Added profiling code to synchronization primitives to find bottlenecks if | |
7bdc931e | 174 | running on multiple cores. Found and fixed an issue where parts of the |
73937bd8 MW |
175 | Diffie-Hellman calculation acquired an exclusive lock. This greatly improves |
176 | parallelization to multiple cores. | |
177 | ||
509e07c5 AS |
178 | - updown script invocation has been separated into a plugin of its own to |
179 | further slim down the daemon core. | |
73937bd8 | 180 | |
509e07c5 | 181 | - Separated IKE_SA/CHILD_SA key derivation process into a closed system, |
7bdc931e | 182 | allowing future implementations to use a secured environment in e.g. kernel |
73937bd8 MW |
183 | memory or hardware. |
184 | ||
509e07c5 AS |
185 | - The kernel interface of charon has been modularized. XFRM NETLINK (default) |
186 | and PFKEY (--enable-kernel-pfkey) interface plugins for the native IPsec | |
187 | stack of the Linux 2.6 kernel as well as a PFKEY interface for the KLIPS | |
188 | IPsec stack (--enable-kernel-klips) are provided. | |
189 | ||
190 | - Basic Mobile IPv6 support has been introduced, securing Binding Update | |
191 | messages as well as tunneled traffic between Mobile Node and Home Agent. | |
192 | The installpolicy=no option allows peaceful cooperation with a dominant | |
193 | mip6d daemon and the new type=transport_proxy implements the special MIPv6 | |
194 | IPsec transport proxy mode where the IKEv2 daemon uses the Care-of-Address | |
195 | but the IPsec SA is set up for the Home Adress. | |
7bdc931e | 196 | |
4dc0dce8 AS |
197 | - Implemented migration of Mobile IPv6 connections using the KMADDRESS |
198 | field contained in XFRM_MSG_MIGRATE messages sent by the mip6d daemon | |
199 | via the Linux 2.6.28 (or appropriately patched) kernel. | |
200 | ||

e39b271b AS |
202 | strongswan-4.2.8 |
203 | ---------------- | |
204 | ||
5dadb16e | 205 | - IKEv2 charon daemon supports authentication based on raw public keys |
e39b271b AS |
206 | stored in the SQL database backend. The ipsec listpubkeys command |
207 | lists the available raw public keys via the stroke interface. | |
208 | ||
4f0241e6 MW |
209 | - Several MOBIKE improvements: Detect changes in NAT mappings in DPD exchanges, |
210 | handle events if kernel detects NAT mapping changes in UDP-encapsulated | |
211 | ESP packets (requires kernel patch), reuse old addesses in MOBIKE updates as | |
212 | long as possible and other fixes. | |
213 | ||
5dadb16e AS |
214 | - Fixed a bug in addr_in_subnet() which caused insertion of wrong source |
215 | routes for destination subnets having netwmasks not being a multiple of 8 bits. | |
216 | Thanks go to Wolfgang Steudel, TU Ilmenau for reporting this bug. | |
217 | ||
e39b271b | 218 | |
e376d75f MW |
219 | strongswan-4.2.7 |
220 | ---------------- | |
221 | ||
b37cda82 AS |
222 | - Fixed a Denial-of-Service vulnerability where an IKE_SA_INIT message with |
223 | a KE payload containing zeroes only can cause a crash of the IKEv2 charon | |
224 | daemon due to a NULL pointer returned by the mpz_export() function of the | |
225 | GNU Multiprecision Library (GMP). Thanks go to Mu Dynamics Research Labs | |
226 | for making us aware of this problem. | |
227 | ||
e376d75f MW |
228 | - The new agent plugin provides a private key implementation on top of an |
229 | ssh-agent. | |
230 | ||
231 | - The NetworkManager plugin has been extended to support certificate client | |
b1f47854 | 232 | authentication using RSA keys loaded from a file or using ssh-agent. |
e376d75f MW |
233 | |
234 | - Daemon capability dropping has been ported to libcap and must be enabled | |
235 | explicitly --with-capabilities=libcap. Future version will support the | |
236 | newer libcap2 library. | |
237 | ||
b37cda82 AS |
238 | - ipsec listalgs lists the IKEv2 cryptografic algorithms registered with the |
239 | charon keying daemon. | |
240 | ||
241 | ||
9f9d6ece AS |
242 | strongswan-4.2.6 |
243 | ---------------- | |
244 | ||
609166f4 MW |
245 | - A NetworkManager plugin allows GUI-based configuration of road-warrior |
246 | clients in a simple way. It features X509 based gateway authentication | |
247 | and EAP client authentication, tunnel setup/teardown and storing passwords | |
248 | in the Gnome Keyring. | |
249 | ||
250 | - A new EAP-GTC plugin implements draft-sheffer-ikev2-gtc-00.txt and allows | |
251 | username/password authentication against any PAM service on the gateway. | |
252 | The new EAP method interacts nicely with the NetworkManager plugin and allows | |
253 | client authentication against e.g. LDAP. | |
254 | ||
255 | - Improved support for the EAP-Identity method. The new ipsec.conf eap_identity | |
256 | parameter defines an additional identity to pass to the server in EAP | |
257 | authentication. | |
258 | ||
9f9d6ece AS |
259 | - The "ipsec statusall" command now lists CA restrictions, EAP |
260 | authentication types and EAP identities. | |
261 | ||
262 | - Fixed two multithreading deadlocks occurring when starting up | |
263 | several hundred tunnels concurrently. | |
264 | ||
265 | - Fixed the --enable-integrity-test configure option which | |
266 | computes a SHA-1 checksum over the libstrongswan library. | |
267 | ||
268 | ||
174216c7 AS |
269 | strongswan-4.2.5 |
270 | ---------------- | |
271 | ||
8124e491 AS |
272 | - Consistent logging of IKE and CHILD SAs at the audit (AUD) level. |
273 | ||
274 | - Improved the performance of the SQL-based virtual IP address pool | |
275 | by introducing an additional addresses table. The leases table | |
276 | storing only history information has become optional and can be | |
277 | disabled by setting charon.plugins.sql.lease_history = no in | |
278 | strongswan.conf. | |
279 | ||
eb0cc338 | 280 | - The XFRM_STATE_AF_UNSPEC flag added to xfrm.h allows IPv4-over-IPv6 |
de5f70e7 | 281 | and IPv6-over-IPv4 tunnels with the 2.6.26 and later Linux kernels. |
eb0cc338 | 282 | |
174216c7 AS |
283 | - management of different virtual IP pools for different |
284 | network interfaces have become possible. | |
285 | ||
286 | - fixed a bug which prevented the assignment of more than 256 | |
287 | virtual IP addresses from a pool managed by an sql database. | |
288 | ||
8124e491 AS |
289 | - fixed a bug which did not delete own IPCOMP SAs in the kernel. |
290 | ||
174216c7 | 291 | |
179dd12c AS |
292 | strongswan-4.2.4 |
293 | ---------------- | |
294 | ||
9de95037 AS |
295 | - Added statistics functions to ipsec pool --status and ipsec pool --leases |
296 | and input validation checks to various ipsec pool commands. | |
179dd12c | 297 | |
73a8eed3 | 298 | - ipsec statusall now lists all loaded charon plugins and displays |
9de95037 | 299 | the negotiated IKEv2 cipher suite proposals. |
73a8eed3 AS |
300 | |
301 | - The openssl plugin supports the elliptic curve Diffie-Hellman groups | |
302 | 19, 20, 21, 25, and 26. | |
303 | ||
304 | - The openssl plugin supports ECDSA authentication using elliptic curve | |
305 | X.509 certificates. | |
306 | ||
307 | - Fixed a bug in stroke which caused multiple charon threads to close | |
308 | the file descriptors during packet transfers over the stroke socket. | |
309 | ||
e0bb4dbb AS |
310 | - ESP sequence numbers are now migrated in IPsec SA updates handled by |
311 | MOBIKE. Works only with Linux kernels >= 2.6.17. | |
312 | ||
179dd12c | 313 | |
83d9e870 AS |
314 | strongswan-4.2.3 |
315 | ---------------- | |
316 | ||
317 | - Fixed the strongswan.conf path configuration problem that occurred when | |
318 | --sysconfig was not set explicitly in ./configure. | |
319 | ||
320 | - Fixed a number of minor bugs that where discovered during the 4th | |
321 | IKEv2 interoperability workshop in San Antonio, TX. | |
322 | ||
323 | ||
7f491111 MW |
324 | strongswan-4.2.2 |
325 | ---------------- | |
326 | ||
a57cd446 AS |
327 | - Plugins for libstrongswan and charon can optionally be loaded according |
328 | to a configuration in strongswan.conf. Most components provide a | |
7f491111 | 329 | "load = " option followed by a space separated list of plugins to load. |
a57cd446 AS |
330 | This allows e.g. the fallback from a hardware crypto accelerator to |
331 | to software-based crypto plugins. | |
7f491111 MW |
332 | |
333 | - Charons SQL plugin has been extended by a virtual IP address pool. | |
a57cd446 AS |
334 | Configurations with a rightsourceip=%poolname setting query a SQLite or |
335 | MySQL database for leases. The "ipsec pool" command helps in administrating | |
336 | the pool database. See ipsec pool --help for the available options | |
337 | ||
338 | - The Authenticated Encryption Algorithms AES-CCM-8/12/16 and AES-GCM-8/12/16 | |
339 | for ESP are now supported starting with the Linux 2.6.25 kernel. The | |
340 | syntax is e.g. esp=aes128ccm12 or esp=aes256gcm16. | |
341 | ||
7f491111 | 342 | |
5c5d67d6 AS |
343 | strongswan-4.2.1 |
344 | ---------------- | |
345 | ||
c306dfb1 | 346 | - Support for "Hash and URL" encoded certificate payloads has been implemented |
b1f8fc0c TB |
347 | in the IKEv2 daemon charon. Using the "certuribase" option of a CA section |
348 | allows to assign a base URL to all certificates issued by the specified CA. | |
349 | The final URL is then built by concatenating that base and the hex encoded | |
350 | SHA1 hash of the DER encoded certificate. Note that this feature is disabled | |
351 | by default and must be enabled using the option "charon.hash_and_url". | |
5c5d67d6 | 352 | |
58caabf7 MW |
353 | - The IKEv2 daemon charon now supports the "uniqueids" option to close multiple |
354 | IKE_SAs with the same peer. The option value "keep" prefers existing | |
355 | connection setups over new ones, where the value "replace" replaces existing | |
356 | connections. | |
357 | ||
358 | - The crypto factory in libstrongswan additionaly supports random number | |
359 | generators, plugins may provide other sources of randomness. The default | |
c306dfb1 | 360 | plugin reads raw random data from /dev/(u)random. |
58caabf7 MW |
361 | |
362 | - Extended the credential framework by a caching option to allow plugins | |
363 | persistent caching of fetched credentials. The "cachecrl" option has been | |
c306dfb1 | 364 | re-implemented. |
58caabf7 MW |
365 | |
366 | - The new trustchain verification introduced in 4.2.0 has been parallelized. | |
367 | Threads fetching CRL or OCSP information no longer block other threads. | |
5c5d67d6 | 368 | |
58caabf7 MW |
369 | - A new IKEv2 configuration attribute framework has been introduced allowing |
370 | plugins to provide virtual IP addresses, and in the future, other | |
371 | configuration attribute services (e.g. DNS/WINS servers). | |
5c5d67d6 | 372 | |
466abb49 | 373 | - The stroke plugin has been extended to provide virtual IP addresses from |
58caabf7 MW |
374 | a pool defined in ipsec.conf. The "rightsourceip" parameter now accepts |
375 | address pools in CIDR notation (e.g. 10.1.1.0/24). The parameter also accepts | |
376 | the value "%poolname", where "poolname" identifies a pool provided by a | |
466abb49 | 377 | separate plugin. |
58caabf7 | 378 | |
c306dfb1 | 379 | - Fixed compilation on uClibc and a couple of other minor bugs. |
58caabf7 | 380 | |
c306dfb1 | 381 | - Set DPD defaults in ipsec starter to dpd_delay=30s and dpd_timeout=150s. |
466abb49 AS |
382 | |
383 | - The IKEv1 pluto daemon now supports the ESP encryption algorithm CAMELLIA | |
c306dfb1 | 384 | with key lengths of 128, 192, and 256 bits, as well as the authentication |
466abb49 AS |
385 | algorithm AES_XCBC_MAC. Configuration example: esp=camellia192-aesxcbc. |
386 | ||
5c5d67d6 | 387 | |
a11ea97d AS |
388 | strongswan-4.2.0 |
389 | ---------------- | |
390 | ||

391 | - libstrongswan has been modularized to attach crypto algorithms, |
392 | credential implementations (keys, certificates) and fetchers dynamically | |
393 | through plugins. Existing code has been ported to plugins: | |
394 | - RSA/Diffie-Hellman implementation using the GNU Multi Precision library | |
395 | - X509 certificate system supporting CRLs, OCSP and attribute certificates | |
396 | - Multiple plugins providing crypto algorithms in software | |
397 | - CURL and OpenLDAP fetcher | |

16f5dacd MW |
399 | - libstrongswan gained a relational database API which uses pluggable database |
400 | providers. Plugins for MySQL and SQLite are available. | |
401 | ||
402 | - The IKEv2 keying daemon charon is more extensible. Generic plugins may provide | |
403 | connection configuration, credentials and EAP methods or control the daemon. | |
404 | Existing code has been ported to plugins: | |
405 | - EAP-AKA, EAP-SIM, EAP-MD5 and EAP-Identity | |
406 | - stroke configuration, credential and control (compatible to pluto) | |
407 | - XML bases management protocol to control and query the daemon | |
408 | The following new plugins are available: | |
409 | - An experimental SQL configuration, credential and logging plugin on | |
410 | top of either MySQL or SQLite | |
411 | - A unit testing plugin to run tests at daemon startup | |
412 | ||
413 | - The authentication and credential framework in charon has been heavily | |
414 | refactored to support modular credential providers, proper | |
415 | CERTREQ/CERT payload exchanges and extensible authorization rules. | |
416 | ||
417 | - The framework of strongSwan Manager has envolved to the web application | |
418 | framework libfast (FastCGI Application Server w/ Templates) and is usable | |
419 | by other applications. | |

422 | strongswan-4.1.11 |
423 | ----------------- | |
fb6d76cd | 424 | |
a561f74d AS |
425 | - IKE rekeying in NAT situations did not inherit the NAT conditions |
426 | to the rekeyed IKE_SA so that the UDP encapsulation was lost with | |
427 | the next CHILD_SA rekeying. | |
428 | ||
429 | - Wrong type definition of the next_payload variable in id_payload.c | |
430 | caused an INVALID_SYNTAX error on PowerPC platforms. | |
fb6d76cd | 431 | |
e6b50b3f AS |
432 | - Implemented IKEv2 EAP-SIM server and client test modules that use |
433 | triplets stored in a file. For details on the configuration see | |
434 | the scenario 'ikev2/rw-eap-sim-rsa'. | |
435 | ||
fb6d76cd | 436 | |
83e0d841 AS |
437 | strongswan-4.1.10 |
438 | ----------------- | |
439 | ||
440 | - Fixed error in the ordering of the certinfo_t records in the ocsp cache that | |
441 | caused multiple entries of the same serial number to be created. | |
442 | ||
fdc7c943 MW |
443 | - Implementation of a simple EAP-MD5 module which provides CHAP |
444 | authentication. This may be interesting in conjunction with certificate | |
445 | based server authentication, as weak passwords can't be brute forced | |
446 | (in contradiction to traditional IKEv2 PSK). | |
447 | ||
448 | - A complete software based implementation of EAP-AKA, using algorithms | |
449 | specified in 3GPP2 (S.S0055). This implementation does not use an USIM, | |
450 | but reads the secrets from ipsec.secrets. Make sure to read eap_aka.h | |
451 | before using it. | |
452 | ||
453 | - Support for vendor specific EAP methods using Expanded EAP types. The | |
454 | interface to EAP modules has been slightly changed, so make sure to | |
455 | check the changes if you're already rolling your own modules. | |

5076770c AS |
458 | strongswan-4.1.9 |
459 | ---------------- | |
460 | ||
800b3356 AS |
461 | - The default _updown script now dynamically inserts and removes ip6tables |
462 | firewall rules if leftfirewall=yes is set in IPv6 connections. New IPv6 | |
463 | net-net and roadwarrior (PSK/RSA) scenarios for both IKEv1 and IKEV2 were | |
464 | added. | |
5076770c | 465 | |
6f274c2a MW |
466 | - Implemented RFC4478 repeated authentication to force EAP/Virtual-IP clients |
467 | to reestablish an IKE_SA within a given timeframe. | |
468 | ||
469 | - strongSwan Manager supports configuration listing, initiation and termination | |
470 | of IKE and CHILD_SAs. | |
471 | ||
472 | - Fixes and improvements to multithreading code. | |
473 | ||
8b678ad4 MW |
474 | - IKEv2 plugins have been renamed to libcharon-* to avoid naming conflicts. |
475 | Make sure to remove the old plugins in $libexecdir/ipsec, otherwise they get | |
476 | loaded twice. | |
5076770c | 477 | |
83e0d841 | 478 | |
b82e8231 AS |
479 | strongswan-4.1.8 |
480 | ---------------- | |
481 | ||
5076770c | 482 | - Removed recursive pthread mutexes since uClibc doesn't support them. |
b82e8231 AS |
483 | |
484 | ||
a4a3632c AS |
485 | strongswan-4.1.7 |
486 | ---------------- | |
487 | ||
488 | - In NAT traversal situations and multiple queued Quick Modes, | |
489 | those pending connections inserted by auto=start after the | |
490 | port floating from 500 to 4500 were erronously deleted. | |
491 | ||
6e193274 | 492 | - Added a "forceencaps" connection parameter to enforce UDP encapsulation |
078b6008 | 493 | to surmount restrictive firewalls. NAT detection payloads are faked to |
6e193274 MW |
494 | simulate a NAT situation and trick the other peer into NAT mode (IKEv2 only). |
495 | ||
496 | - Preview of strongSwan Manager, a web based configuration and monitoring | |
497 | application. It uses a new XML control interface to query the IKEv2 daemon | |
498 | (see http://trac.strongswan.org/wiki/Manager). | |
499 | ||
500 | - Experimental SQLite configuration backend which will provide the configuration | |
501 | interface for strongSwan Manager in future releases. | |
502 | ||
503 | - Further improvements to MOBIKE support. | |
504 | ||
a4a3632c | 505 | |
3dcf9dbd AS |
506 | strongswan-4.1.6 |
507 | ---------------- | |
508 | ||
3eac4dfd AS |
509 | - Since some third party IKEv2 implementations run into |
510 | problems with strongSwan announcing MOBIKE capability per | |
511 | default, MOBIKE can be disabled on a per-connection-basis | |
512 | using the mobike=no option. Whereas mobike=no disables the | |
513 | sending of the MOBIKE_SUPPORTED notification and the floating | |
514 | to UDP port 4500 with the IKE_AUTH request even if no NAT | |
515 | situation has been detected, strongSwan will still support | |
516 | MOBIKE acting as a responder. | |
517 | ||
518 | - the default ipsec routing table plus its corresponding priority | |
519 | used for inserting source routes has been changed from 100 to 220. | |
520 | It can be configured using the --with-ipsec-routing-table and | |
521 | --with-ipsec-routing-table-prio options. | |
522 | ||
bdc0b55b AS |
523 | - the --enable-integrity-test configure option tests the |
524 | integrity of the libstrongswan crypto code during the charon | |
525 | startup. | |
526 | ||
3eac4dfd AS |
527 | - the --disable-xauth-vid configure option disables the sending |
528 | of the XAUTH vendor ID. This can be used as a workaround when | |
529 | interoperating with some Windows VPN clients that get into | |
530 | trouble upon reception of an XAUTH VID without eXtended | |
531 | AUTHentication having been configured. | |
532 | ||
f872f9d1 AS |
533 | - ipsec stroke now supports the rereadsecrets, rereadaacerts, |
534 | rereadacerts, and listacerts options. | |
3dcf9dbd AS |
535 | |
536 | ||
7ad634a2 AS |
537 | strongswan-4.1.5 |
538 | ---------------- | |
539 | ||
540 | - If a DNS lookup failure occurs when resolving right=%<FQDN> | |
541 | or right=<FQDN> combined with rightallowany=yes then the | |
542 | connection is not updated by ipsec starter thus preventing | |
543 | the disruption of an active IPsec connection. Only if the DNS | |
544 | lookup successfully returns with a changed IP address the | |
545 | corresponding connection definition is updated. | |
546 | ||
8f5b363c MW |
547 | - Routes installed by the keying daemons are now in a separate |
548 | routing table with the ID 100 to avoid conflicts with the main | |
549 | table. Route lookup for IKEv2 traffic is done in userspace to ignore | |
550 | routes installed for IPsec, as IKE traffic shouldn't get encapsulated. | |
551 | ||
7ad634a2 | 552 | |
e93c68ba AS |
553 | strongswan-4.1.4 |
554 | ---------------- | |
555 | ||
556 | - The pluto IKEv1 daemon now exhibits the same behaviour as its | |
557 | IKEv2 companion charon by inserting an explicit route via the | |
558 | _updown script only if a sourceip exists. This is admissible | |
559 | since routing through the IPsec tunnel is handled automatically | |
b7af55ac AS |
560 | by NETKEY's IPsec policies. As a consequence the left|rightnexthop |
561 | parameter is not required any more. | |
078ce348 AS |
562 | |
563 | - The new IKEv1 parameter right|leftallowany parameters helps to handle | |
564 | the case where both peers possess dynamic IP addresses that are | |
565 | usually resolved using DynDNS or a similar service. The configuration | |
566 | ||
567 | right=peer.foo.bar | |
568 | rightallowany=yes | |
569 | ||
570 | can be used by the initiator to start up a connection to a peer | |
571 | by resolving peer.foo.bar into the currently allocated IP address. | |
572 | Thanks to the rightallowany flag the connection behaves later on | |
573 | as | |
574 | ||
575 | right=%any | |
576 | ||
577 | so that the peer can rekey the connection as an initiator when his | |
1fbdab85 AS |
578 | IP address changes. An alternative notation is |
579 | ||
580 | right=%peer.foo.bar | |
581 | ||
582 | which will implicitly set rightallowany=yes. | |
583 | ||
584 | - ipsec starter now fails more gracefully in the presence of parsing | |
585 | errors. Flawed ca and conn section are discarded and pluto is started | |
586 | if non-fatal errors only were encountered. If right=%peer.foo.bar | |
587 | cannot be resolved by DNS then right=%any will be used so that passive | |
588 | connections as a responder are still possible. | |
078ce348 | 589 | |
a0a0bdd7 AS |
590 | - The new pkcs11initargs parameter that can be placed in the |
591 | setup config section of /etc/ipsec.conf allows the definition | |
592 | of an argument string that is used with the PKCS#11 C_Initialize() | |
593 | function. This non-standard feature is required by the NSS softoken | |
594 | library. This patch was contributed by Robert Varga. | |
595 | ||
596 | - Fixed a bug in ipsec starter introduced by strongswan-2.8.5 | |
597 | which caused a segmentation fault in the presence of unknown | |
598 | or misspelt keywords in ipsec.conf. This bug fix was contributed | |
599 | by Robert Varga. | |
600 | ||
e3606f2b MW |
601 | - Partial support for MOBIKE in IKEv2. The initiator acts on interface/ |
602 | address configuration changes and updates IKE and IPsec SAs dynamically. | |
e93c68ba | 603 | |
06651827 | 604 | |
a3354a69 AS |
605 | strongswan-4.1.3 |
606 | ---------------- | |
607 | ||
41e16cf4 | 608 | - IKEv2 peer configuration selection now can be based on a given |
35d4809c AS |
609 | certification authority using the rightca= statement. |
610 | ||
611 | - IKEv2 authentication based on RSA signatures now can handle multiple | |
41e16cf4 AS |
612 | certificates issued for a given peer ID. This allows a smooth transition |
613 | in the case of a peer certificate renewal. | |
a3354a69 | 614 | |
998ca0ea MW |
615 | - IKEv2: Support for requesting a specific virtual IP using leftsourceip on the |
616 | client and returning requested virtual IPs using rightsourceip=%config | |
617 | on the server. If the server does not support configuration payloads, the | |
618 | client enforces its leftsourceip parameter. | |
619 | ||
620 | - The ./configure options --with-uid/--with-gid allow pluto and charon | |
621 | to drop their privileges to a minimum and change to an other UID/GID. This | |
622 | improves the systems security, as a possible intruder may only get the | |
623 | CAP_NET_ADMIN capability. | |
624 | ||
625 | - Further modularization of charon: Pluggable control interface and | |
626 | configuration backend modules provide extensibility. The control interface | |
627 | for stroke is included, and further interfaces using DBUS (NetworkManager) | |
628 | or XML are on the way. A backend for storing configurations in the daemon | |
629 | is provided and more advanced backends (using e.g. a database) are trivial | |
630 | to implement. | |
a3354a69 | 631 | |
41e16cf4 AS |
632 | - Fixed a compilation failure in libfreeswan occuring with Linux kernel |
633 | headers > 2.6.17. | |
634 | ||
635 | ||
8ea7b96f AS |
636 | strongswan-4.1.2 |
637 | ---------------- | |
638 | ||
e23d98a7 | 639 | - Support for an additional Diffie-Hellman exchange when creating/rekeying |
37fb0355 MW |
640 | a CHILD_SA in IKEv2 (PFS). PFS is enabled when the proposal contains a |
641 | DH group (e.g. "esp=aes128-sha1-modp1536"). Further, DH group negotiation | |
642 | is implemented properly for rekeying. | |
643 | ||
644 | - Support for the AES-XCBC-96 MAC algorithm for IPsec SAs when using IKEv2 | |
645 | (requires linux >= 2.6.20). It is enabled using e.g. "esp=aes256-aesxcbc". | |
646 | ||
d931f465 MW |
647 | - Working IPv4-in-IPv6 and IPv6-in-IPv4 tunnels for linux >= 2.6.21. |
648 | ||
37fb0355 MW |
649 | - Added support for EAP modules which do not establish an MSK. |
650 | ||
dfbe2a0f | 651 | - Removed the dependencies from the /usr/include/linux/ headers by |
9f78f957 | 652 | including xfrm.h, ipsec.h, and pfkeyv2.h in the distribution. |
dfbe2a0f | 653 | |
9f78f957 AS |
654 | - crlNumber is now listed by ipsec listcrls |
655 | ||
8ea7b96f AS |
656 | - The xauth_modules.verify_secret() function now passes the |
657 | connection name. | |
658 | ||
e23d98a7 | 659 | |
ed284399 MW |
660 | strongswan-4.1.1 |
661 | ---------------- | |
662 | ||
663 | - Server side cookie support. If to may IKE_SAs are in CONNECTING state, | |
664 | cookies are enabled and protect against DoS attacks with faked source | |
665 | addresses. Number of IKE_SAs in CONNECTING state is also limited per | |
666 | peer address to avoid resource exhaustion. IKE_SA_INIT messages are | |
667 | compared to properly detect retransmissions and incoming retransmits are | |
668 | detected even if the IKE_SA is blocked (e.g. doing OCSP fetches). | |
669 | ||
db88e37d AS |
670 | - The IKEv2 daemon charon now supports dynamic http- and ldap-based CRL |
671 | fetching enabled by crlcheckinterval > 0 and caching fetched CRLs | |
672 | enabled by cachecrls=yes. | |
673 | ||
3b4f7d92 AS |
674 | - Added the configuration options --enable-nat-transport which enables |
675 | the potentially insecure NAT traversal for IPsec transport mode and | |
676 | --disable-vendor-id which disables the sending of the strongSwan | |
677 | vendor ID. | |
678 | ||
679 | - Fixed a long-standing bug in the pluto IKEv1 daemon which caused | |
680 | a segmentation fault if a malformed payload was detected in the | |
681 | IKE MR2 message and pluto tried to send an encrypted notification | |
682 | message. | |
683 | ||
46b9ff68 AS |
684 | - Added the NATT_IETF_02_N Vendor ID in order to support IKEv1 connections |
685 | with Windows 2003 Server which uses a wrong VID hash. | |
686 | ||
3b4f7d92 | 687 | |
34bbd0c3 | 688 | strongswan-4.1.0 |
cd3958f8 AS |
689 | ---------------- |
690 | ||
691 | - Support of SHA2_384 hash function for protecting IKEv1 | |
692 | negotiations and support of SHA2 signatures in X.509 certificates. | |
693 | ||
694 | - Fixed a serious bug in the computation of the SHA2-512 HMAC | |
695 | function. Introduced automatic self-test of all IKEv1 hash | |
696 | and hmac functions during pluto startup. Failure of a self-test | |
697 | currently issues a warning only but does not exit pluto [yet]. | |
698 | ||
9b45443d MW |
699 | - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2. |
700 | ||
c5d0fbb6 AS |
701 | - Full support of CA information sections. ipsec listcainfos |
702 | now shows all collected crlDistributionPoints and OCSP | |
703 | accessLocations. | |
704 | ||
69ed04bf AS |
705 | - Support of the Online Certificate Status Protocol (OCSP) for IKEv2. |
706 | This feature requires the HTTP fetching capabilities of the libcurl | |
707 | library which must be enabled by setting the --enable-http configure | |
708 | option. | |
709 | ||
9b45443d MW |
710 | - Refactored core of the IKEv2 message processing code, allowing better |
711 | code reuse and separation. | |
712 | ||
713 | - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration | |
714 | payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted | |
715 | by the requestor and installed in a resolv.conf file. | |
716 | ||
717 | - The IKEv2 daemon charon installs a route for each IPsec policy to use | |
718 | the correct source address even if an application does not explicitly | |
719 | specify it. | |
720 | ||
721 | - Integrated the EAP framework into charon which loads pluggable EAP library | |
722 | modules. The ipsec.conf parameter authby=eap initiates EAP authentication | |
723 | on the client side, while the "eap" parameter on the server side defines | |
724 | the EAP method to use for client authentication. | |
725 | A generic client side EAP-Identity module and an EAP-SIM authentication | |
726 | module using a third party card reader implementation are included. | |
727 | ||
728 | - Added client side support for cookies. | |
729 | ||
730 | - Integrated the fixes done at the IKEv2 interoperability bakeoff, including | |
731 | strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor | |
732 | fixes to enhance interoperability with other implementations. | |
cd3958f8 | 733 | |

735 | strongswan-4.0.7 |
736 | ---------------- | |
737 | ||
6fdf5f44 AS |
738 | - strongSwan now interoperates with the NCP Secure Entry Client, |
739 | the Shrew Soft VPN Client, and the Cisco VPN client, doing both | |
740 | XAUTH and Mode Config. | |
1c266d7d AS |
741 | |
742 | - UNITY attributes are now recognized and UNITY_BANNER is set | |
743 | to a default string. | |
744 | ||
745 | ||
2b4405a3 MW |
746 | strongswan-4.0.6 |
747 | ---------------- | |
748 | ||
e38a15d4 AS |
749 | - IKEv1: Support for extended authentication (XAUTH) in combination |
750 | with ISAKMP Main Mode RSA or PSK authentication. Both client and | |
751 | server side were implemented. Handling of user credentials can | |
752 | be done by a run-time loadable XAUTH module. By default user | |
753 | credentials are stored in ipsec.secrets. | |
754 | ||
2b4405a3 MW |
755 | - IKEv2: Support for reauthentication when rekeying |
756 | ||
5903179b | 757 | - IKEv2: Support for transport mode |
af87afed | 758 | |
5903179b | 759 | - fixed a lot of bugs related to byte order |
2b4405a3 | 760 | |
5903179b | 761 | - various other bugfixes |
2b4405a3 MW |

763 | ||
0cd645d2 AS |
764 | strongswan-4.0.5 |
765 | ---------------- | |
766 | ||
767 | - IKEv1: Implementation of ModeConfig push mode via the new connection | |
768 | keyword modeconfig=push allows interoperability with Cisco VPN gateways. | |
769 | ||
770 | - IKEv1: The command ipsec statusall now shows "DPD active" for all | |
771 | ISAKMP SAs that are under active Dead Peer Detection control. | |
772 | ||
773 | - IKEv2: Charon's logging and debugging framework has been completely rewritten. | |
774 | Instead of logger, special printf() functions are used to directly | |
775 | print objects like hosts (%H) identifications (%D), certificates (%Q), | |
776 | etc. The number of debugging levels have been reduced to: | |
03bf883d | 777 | |
0cd645d2 | 778 | 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private) |
03bf883d | 779 | |
0cd645d2 AS |
780 | The debugging levels can either be specified statically in ipsec.conf as |
781 | ||
782 | config setup | |
03bf883d | 783 | charondebug="lib 1, cfg 3, net 2" |
0cd645d2 | 784 | |
03bf883d | 785 | or changed at runtime via stroke as |

789 | ||
48dc3934 MW |
790 | strongswan-4.0.4 |
791 | ---------------- | |
792 | ||
793 | - Implemented full support for IPv6-in-IPv6 tunnels. | |
794 | ||
795 | - Added configuration options for dead peer detection in IKEv2. dpd_action | |
796 | types "clear", "hold" and "restart" are supported. The dpd_timeout | |
797 | value is not used, as the normal retransmission policy applies to | |
798 | detect dead peers. The dpd_delay parameter enables sending of empty | |
799 | informational message to detect dead peers in case of inactivity. | |
800 | ||
801 | - Added support for preshared keys in IKEv2. PSK keys configured in | |
802 | ipsec.secrets are loaded. The authby parameter specifies the authentication | |
803 | method to authentificate ourself, the other peer may use PSK or RSA. | |
804 | ||
805 | - Changed retransmission policy to respect the keyingtries parameter. | |
806 | ||
112ad7c3 AS |
807 | - Added private key decryption. PEM keys encrypted with AES-128/192/256 |
808 | or 3DES are supported. | |
48dc3934 MW |
809 | |
810 | - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to | |
811 | encrypt IKE traffic. | |
812 | ||
813 | - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates | |
814 | signed with such a hash algorithm. | |
815 | ||
816 | - Added initial support for updown scripts. The actions up-host/client and | |
817 | down-host/client are executed. The leftfirewall=yes parameter | |
818 | uses the default updown script to insert dynamic firewall rules, a custom | |
819 | updown script may be specified with the leftupdown parameter. | |
820 | ||
821 | ||
a1310b6b MW |
822 | strongswan-4.0.3 |
823 | ---------------- | |
824 | ||
825 | - Added support for the auto=route ipsec.conf parameter and the | |
826 | ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and | |
827 | CHILD_SAs dynamically on demand when traffic is detected by the | |
828 | kernel. | |
829 | ||
830 | - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter. | |
831 | As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only | |
832 | new keys are generated using perfect forward secrecy. An optional flag | |
833 | which enforces reauthentication will be implemented later. | |
834 | ||
b425d998 AS |
835 | - "sha" and "sha1" are now treated as synonyms in the ike= and esp= |
836 | algorithm configuration statements. | |
837 | ||
838 | ||
bf4df11f AS |
839 | strongswan-4.0.2 |
840 | ---------------- | |
841 | ||
623d3dcf AS |
842 | - Full X.509 certificate trust chain verification has been implemented. |
843 | End entity certificates can be exchanged via CERT payloads. The current | |
844 | default is leftsendcert=always, since CERTREQ payloads are not supported | |
845 | yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls. | |
efa40c11 MW |
846 | |
847 | - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2 | |
848 | would offer more possibilities for traffic selection, but the Linux kernel | |
849 | currently does not support it. That's why we stick with these simple | |
850 | ipsec.conf rules for now. | |
851 | ||
623d3dcf AS |
852 | - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no |
853 | IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear, | |
854 | dpddelay=60s). | |
855 | ||
efa40c11 MW |
856 | - Initial NAT traversal support in IKEv2. Charon includes NAT detection |
857 | notify payloads to detect NAT routers between the peers. It switches | |
858 | to port 4500, uses UDP encapsulated ESP packets, handles peer address | |
859 | changes gracefully and sends keep alive message periodically. | |
860 | ||
861 | - Reimplemented IKE_SA state machine for charon, which allows simultaneous | |
862 | rekeying, more shared code, cleaner design, proper retransmission | |
863 | and a more extensible code base. | |
864 | ||
cfd8b27f AS |
865 | - The mixed PSK/RSA roadwarrior detection capability introduced by the |
866 | strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal | |
867 | payloads by the responder right before any defined IKE Main Mode state had | |
868 | been established. Although any form of bad proposal syntax was being correctly | |
869 | detected by the payload parser, the subsequent error handler didn't check | |
870 | the state pointer before logging current state information, causing an | |
871 | immediate crash of the pluto keying daemon due to a NULL pointer. | |
872 | ||
bf4df11f | 873 | |
7e81e975 MW |
874 | strongswan-4.0.1 |
875 | ---------------- | |
876 | ||
c15c3d4b MW |
877 | - Added algorithm selection to charon: New default algorithms for |
878 | ike=aes128-sha-modp2048, as both daemons support it. The default | |
879 | for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles | |
880 | the ike/esp parameter the same way as pluto. As this syntax does | |
881 | not allow specification of a pseudo random function, the same | |
882 | algorithm as for integrity is used (currently sha/md5). Supported | |
883 | algorithms for IKE: | |
884 | Encryption: aes128, aes192, aes256 | |
885 | Integrity/PRF: md5, sha (using hmac) | |
886 | DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192 | |
887 | and for ESP: | |
888 | Encryption: aes128, aes192, aes256, 3des, blowfish128, | |
889 | blowfish192, blowfish256 | |
890 | Integrity: md5, sha1 | |
891 | More IKE encryption algorithms will come after porting libcrypto into | |
892 | libstrongswan. | |
f2c2d395 | 893 | |
c15c3d4b MW |
894 | - initial support for rekeying CHILD_SAs using IKEv2. Currently no |
895 | perfect forward secrecy is used. The rekeying parameters rekey, | |
22ff6f57 | 896 | rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported |
c15c3d4b MW |
897 | when using IKEv2. WARNING: charon currently is unable to handle |
898 | simultaneous rekeying. To avoid such a situation, use a large | |
899 | rekeyfuzz, or even better, set rekey=no on one peer. | |
22ff6f57 | 900 | |
7e81e975 MW |
901 | - support for host2host, net2net, host2net (roadwarrior) tunnels |
902 | using predefined RSA certificates (see uml scenarios for | |
903 | configuration examples). | |
904 | ||
f2c2d395 MW |
905 | - new build environment featuring autotools. Features such |
906 | as HTTP, LDAP and smartcard support may be enabled using | |
907 | the ./configure script. Changing install directories | |
908 | is possible, too. See ./configure --help for more details. | |
909 | ||
22ff6f57 MW |
910 | - better integration of charon with ipsec starter, which allows |
911 | (almost) transparent operation with both daemons. charon | |
912 | handles ipsec commands up, down, status, statusall, listall, | |
913 | listcerts and allows proper load, reload and delete of connections | |
914 | via ipsec starter. | |
915 | ||
b425d998 | 916 | |
9820c0e2 MW |
917 | strongswan-4.0.0 |
918 | ---------------- | |
919 | ||
920 | - initial support of the IKEv2 protocol. Connections in | |
921 | ipsec.conf designated by keyexchange=ikev2 are negotiated | |
922 | by the new IKEv2 charon keying daemon whereas those marked | |
923 | by keyexchange=ikev1 or the default keyexchange=ike are | |
924 | handled thy the IKEv1 pluto keying daemon. Currently only | |
925 | a limited subset of functions are available with IKEv2 | |
926 | (Default AES encryption, authentication based on locally | |
927 | imported X.509 certificates, unencrypted private RSA keys | |
928 | in PKCS#1 file format, limited functionality of the ipsec | |
929 | status command). | |
930 | ||
931 | ||
997358a6 MW |
932 | strongswan-2.7.0 |
933 | ---------------- | |
934 | ||
935 | - the dynamic iptables rules from the _updown_x509 template | |
936 | for KLIPS and the _updown_policy template for NETKEY have | |
937 | been merged into the default _updown script. The existing | |
938 | left|rightfirewall keyword causes the automatic insertion | |
939 | and deletion of ACCEPT rules for tunneled traffic upon | |
940 | the successful setup and teardown of an IPsec SA, respectively. | |
941 | left|rightfirwall can be used with KLIPS under any Linux 2.4 | |
942 | kernel or with NETKEY under a Linux kernel version >= 2.6.16 | |
943 | in conjuction with iptables >= 1.3.5. For NETKEY under a Linux | |
944 | kernel version < 2.6.16 which does not support IPsec policy | |
945 | matching yet, please continue to use a copy of the _updown_espmark | |
946 | template loaded via the left|rightupdown keyword. | |
947 | ||
948 | - a new left|righthostaccess keyword has been introduced which | |
949 | can be used in conjunction with left|rightfirewall and the | |
950 | default _updown script. By default leftfirewall=yes inserts | |
951 | a bi-directional iptables FORWARD rule for a local client network | |
952 | with a netmask different from 255.255.255.255 (single host). | |
953 | This does not allow to access the VPN gateway host via its | |
954 | internal network interface which is part of the client subnet | |
955 | because an iptables INPUT and OUTPUT rule would be required. | |
956 | lefthostaccess=yes will cause this additional ACCEPT rules to | |
957 | be inserted. | |
958 | ||
959 | - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal | |
960 | payload is preparsed in order to find out whether the roadwarrior | |
961 | requests PSK or RSA so that a matching connection candidate can | |
962 | be found. | |
963 | ||
964 | ||
965 | strongswan-2.6.4 | |
966 | ---------------- | |
967 | ||
968 | - the new _updown_policy template allows ipsec policy based | |
969 | iptables firewall rules. Required are iptables version | |
970 | >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes | |
971 | the _updown_espmark template, so that no INPUT mangle rules | |
972 | are required any more. | |
973 | ||
974 | - added support of DPD restart mode | |
975 | ||
976 | - ipsec starter now allows the use of wildcards in include | |
977 | statements as e.g. in "include /etc/my_ipsec/*.conf". | |
978 | Patch courtesy of Matthias Haas. | |
979 | ||
980 | - the Netscape OID 'employeeNumber' is now recognized and can be | |
981 | used as a Relative Distinguished Name in certificates. | |
982 | ||
983 | ||
984 | strongswan-2.6.3 | |
985 | ---------------- | |
986 | ||
987 | - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec | |
988 | command and not of ipsec setup any more. | |
989 | ||
990 | - ipsec starter now supports AH authentication in conjunction with | |
991 | ESP encryption. AH authentication is configured in ipsec.conf | |
992 | via the auth=ah parameter. | |
993 | ||
994 | - The command ipsec scencrypt|scdecrypt <args> is now an alias for | |
995 | ipsec whack --scencrypt|scdecrypt <args>. | |
996 | ||
997 | - get_sa_info() now determines for the native netkey IPsec stack | |
998 | the exact time of the last use of an active eroute. This information | |
999 | is used by the Dead Peer Detection algorithm and is also displayed by | |
1000 | the ipsec status command. | |
1001 | ||
1002 | ||
1003 | strongswan-2.6.2 | |
1004 | ---------------- | |
1005 | ||
1006 | - running under the native Linux 2.6 IPsec stack, the function | |
1007 | get_sa_info() is called by ipsec auto --status to display the current | |
1008 | number of transmitted bytes per IPsec SA. | |
1009 | ||
1010 | - get_sa_info() is also used by the Dead Peer Detection process to detect | |
1011 | recent ESP activity. If ESP traffic was received from the peer within | |
1012 | the last dpd_delay interval then no R_Y_THERE notification must be sent. | |
1013 | ||
1014 | - strongSwan now supports the Relative Distinguished Name "unstructuredName" | |
1015 | in ID_DER_ASN1_DN identities. The following notations are possible: | |
1016 | ||
1017 | rightid="unstructuredName=John Doe" | |
1018 | rightid="UN=John Doe" | |
1019 | ||
1020 | - fixed a long-standing bug which caused PSK-based roadwarrior connections | |
1021 | to segfault in the function id.c:same_id() called by keys.c:get_secret() | |
1022 | if an FQDN, USER_FQDN, or Key ID was defined, as in the following example. | |
1023 | ||
1024 | conn rw | |
1025 | right=%any | |
1026 | rightid=@foo.bar | |
1027 | authby=secret | |
1028 | ||
1029 | - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall). | |
1030 | ||
1031 | - ipsec starter didn't set host_addr and client.addr ports in whack msg. | |
1032 | ||
1033 | - in order to guarantee backwards-compatibility with the script-based | |
1034 | auto function (e.g. auto --replace), the ipsec starter scripts stores | |
1035 | the defaultroute information in the temporary file /var/run/ipsec.info. | |
1036 | ||
1037 | - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH | |
1038 | Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config | |
1039 | servers. | |
1040 | ||
1041 | - the ipsec starter now also recognizes the parameters authby=never and | |
1042 | type=passthrough|pass|drop|reject. | |
1043 | ||
1044 | ||
1045 | strongswan-2.6.1 | |
1046 | ---------------- | |
1047 | ||
1048 | - ipsec starter now supports the also parameter which allows | |
1049 | a modular structure of the connection definitions. Thus | |
1050 | "ipsec start" is now ready to replace "ipsec setup". | |
1051 | ||
1052 | ||
1053 | strongswan-2.6.0 | |
1054 | ---------------- | |
1055 | ||
1056 | - Mathieu Lafon's popular ipsec starter tool has been added to the | |
1057 | strongSwan distribution. Many thanks go to Stephan Scholz from astaro | |
1058 | for his integration work. ipsec starter is a C program which is going | |
1059 | to replace the various shell and awk starter scripts (setup, _plutoload, | |
1060 | _plutostart, _realsetup, _startklips, _confread, and auto). Since | |
1061 | ipsec.conf is now parsed only once, the starting of multiple tunnels is | |
1062 | accelerated tremedously. | |
1063 | ||
1064 | - Added support of %defaultroute to the ipsec starter. If the IP address | |
1065 | changes, a HUP signal to the ipsec starter will automatically | |
1066 | reload pluto's connections. | |
1067 | ||
1068 | - moved most compile time configurations from pluto/Makefile to | |
1069 | Makefile.inc by defining the options USE_LIBCURL, USE_LDAP, | |
1070 | USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE. | |
1071 | ||
1072 | - removed the ipsec verify and ipsec newhostkey commands | |
1073 | ||
1074 | - fixed some 64-bit issues in formatted print statements | |
1075 | ||
1076 | - The scepclient functionality implementing the Simple Certificate | |
1077 | Enrollment Protocol (SCEP) is nearly complete but hasn't been | |
1078 | documented yet. | |
1079 | ||
1080 | ||
1081 | strongswan-2.5.7 | |
1082 | ---------------- | |
1083 | ||
1084 | - CA certicates are now automatically loaded from a smartcard | |
1085 | or USB crypto token and appear in the ipsec auto --listcacerts | |
1086 | listing. | |
1087 | ||
1088 | ||
1089 | strongswan-2.5.6 | |
1090 | ---------------- | |
1091 | ||
1092 | - when using "ipsec whack --scencrypt <data>" with a PKCS#11 | |
1093 | library that does not support the C_Encrypt() Cryptoki | |
1094 | function (e.g. OpenSC), the RSA encryption is done in | |
1095 | software using the public key fetched from the smartcard. | |
1096 | ||
1097 | - The scepclient function now allows to define the | |
1098 | validity of a self-signed certificate using the --days, | |
1099 | --startdate, and --enddate options. The default validity | |
1100 | has been changed from one year to five years. | |
1101 | ||
1102 | ||
1103 | strongswan-2.5.5 | |
1104 | ---------------- | |
1105 | ||
1106 | - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11 | |
1107 | interface to other applications for RSA encryption and decryption | |
1108 | via the whack interface. Notation: | |
1109 | ||
1110 | ipsec whack --scencrypt <data> | |
1111 | [--inbase 16|hex|64|base64|256|text|ascii] | |
1112 | [--outbase 16|hex|64|base64|256|text|ascii] | |
1113 | [--keyid <keyid>] | |
1114 | ||
1115 | ipsec whack --scdecrypt <data> | |
1116 | [--inbase 16|hex|64|base64|256|text|ascii] | |
1117 | [--outbase 16|hex|64|base64|256|text|ascii] | |
1118 | [--keyid <keyid>] | |
1119 | ||
1120 | The default setting for inbase and outbase is hex. | |
1121 | ||
1122 | The new proxy interface can be used for securing symmetric | |
1123 | encryption keys required by the cryptoloop or dm-crypt | |
1124 | disk encryption schemes, especially in the case when | |
1125 | pkcs11keepstate=yes causes pluto to lock the pkcs11 slot | |
1126 | permanently. | |
1127 | ||
1128 | - if the file /etc/ipsec.secrets is lacking during the startup of | |
1129 | pluto then the root-readable file /etc/ipsec.d/private/myKey.der | |
1130 | containing a 2048 bit RSA private key and a matching self-signed | |
1131 | certificate stored in the file /etc/ipsec.d/certs/selfCert.der | |
1132 | is automatically generated by calling the function | |
1133 | ||
1134 | ipsec scepclient --out pkcs1 --out cert-self | |
1135 | ||
1136 | scepclient was written by Jan Hutter and Martin Willi, students | |
1137 | at the University of Applied Sciences in Rapperswil, Switzerland. | |
1138 | ||
1139 | ||
1140 | strongswan-2.5.4 | |
1141 | ---------------- | |
1142 | ||
1143 | - the current extension of the PKCS#7 framework introduced | |
1144 | a parsing error in PKCS#7 wrapped X.509 certificates that are | |
1145 | e.g. transmitted by Windows XP when multi-level CAs are used. | |
1146 | the parsing syntax has been fixed. | |
1147 | ||
1148 | - added a patch by Gerald Richter which tolerates multiple occurrences | |
1149 | of the ipsec0 interface when using KLIPS. | |
1150 | ||
1151 | ||
1152 | strongswan-2.5.3 | |
1153 | ---------------- | |
1154 | ||
1155 | - with gawk-3.1.4 the word "default2 has become a protected | |
1156 | keyword for use in switch statements and cannot be used any | |
1157 | more in the strongSwan scripts. This problem has been | |
1158 | solved by renaming "default" to "defaults" and "setdefault" | |
1159 | in the scripts _confread and auto, respectively. | |
1160 | ||
1161 | - introduced the parameter leftsendcert with the values | |
1162 | ||
1163 | always|yes (the default, always send a cert) | |
1164 | ifasked (send the cert only upon a cert request) | |
1165 | never|no (never send a cert, used for raw RSA keys and | |
1166 | self-signed certs) | |
1167 | ||
1168 | - fixed the initialization of the ESP key length to a default of | |
1169 | 128 bits in the case that the peer does not send a key length | |
1170 | attribute for AES encryption. | |
1171 | ||
1172 | - applied Herbert Xu's uniqueIDs patch | |
1173 | ||
1174 | - applied Herbert Xu's CLOEXEC patches | |
1175 | ||
1176 | ||
1177 | strongswan-2.5.2 | |
1178 | ---------------- | |
1179 | ||
1180 | - CRLs can now be cached also in the case when the issuer's | |
1181 | certificate does not contain a subjectKeyIdentifier field. | |
1182 | In that case the subjectKeyIdentifier is computed by pluto as the | |
1183 | 160 bit SHA-1 hash of the issuer's public key in compliance | |
1184 | with section 4.2.1.2 of RFC 3280. | |
1185 | ||
1186 | - Fixed a bug introduced by strongswan-2.5.1 which eliminated | |
1187 | not only multiple Quick Modes of a given connection but also | |
1188 | multiple connections between two security gateways. | |
1189 | ||
1190 | ||
1191 | strongswan-2.5.1 | |
1192 | ---------------- | |
1193 | ||
1194 | - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute | |
1195 | installed either by setting auto=route in ipsec.conf or by | |
1196 | a connection put into hold, generates an XFRM_AQUIRE event | |
1197 | for each packet that wants to use the not-yet exisiting | |
1198 | tunnel. Up to now each XFRM_AQUIRE event led to an entry in | |
1199 | the Quick Mode queue, causing multiple IPsec SA to be | |
1200 | established in rapid succession. Starting with strongswan-2.5.1 | |
1201 | only a single IPsec SA is established per host-pair connection. | |
1202 | ||
1203 | - Right after loading the PKCS#11 module, all smartcard slots are | |
1204 | searched for certificates. The result can be viewed using | |
1205 | the command | |
1206 | ||
1207 | ipsec auto --listcards | |
1208 | ||
1209 | The certificate objects found in the slots are numbered | |
1210 | starting with #1, #2, etc. This position number can be used to address | |
1211 | certificates (leftcert=%smartcard) and keys (: PIN %smartcard) | |
1212 | in ipsec.conf and ipsec.secrets, respectively: | |
1213 | ||
1214 | %smartcard (selects object #1) | |
1215 | %smartcard#1 (selects object #1) | |
1216 | %smartcard#3 (selects object #3) | |
1217 | ||
1218 | As an alternative the existing retrieval scheme can be used: | |
1219 | ||
1220 | %smartcard:45 (selects object with id=45) | |
1221 | %smartcard0 (selects first object in slot 0) | |
1222 | %smartcard4:45 (selects object in slot 4 with id=45) | |
1223 | ||
1224 | - Depending on the settings of CKA_SIGN and CKA_DECRYPT | |
1225 | private key flags either C_Sign() or C_Decrypt() is used | |
1226 | to generate a signature. | |
1227 | ||
1228 | - The output buffer length parameter siglen in C_Sign() | |
1229 | is now initialized to the actual size of the output | |
1230 | buffer prior to the function call. This fixes the | |
1231 | CKR_BUFFER_TOO_SMALL error that could occur when using | |
1232 | the OpenSC PKCS#11 module. | |
1233 | ||
1234 | - Changed the initialization of the PKCS#11 CK_MECHANISM in | |
1235 | C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }. | |
1236 | ||
1237 | - Refactored the RSA public/private key code and transferred it | |
1238 | from keys.c to the new pkcs1.c file as a preparatory step | |
1239 | towards the release of the SCEP client. | |
1240 | ||
1241 | ||
1242 | strongswan-2.5.0 | |
1243 | ---------------- | |
1244 | ||
1245 | - The loading of a PKCS#11 smartcard library module during | |
1246 | runtime does not require OpenSC library functions any more | |
1247 | because the corresponding code has been integrated into | |
1248 | smartcard.c. Also the RSAREF pkcs11 header files have been | |
1249 | included in a newly created pluto/rsaref directory so that | |
1250 | no external include path has to be defined any longer. | |
1251 | ||
1252 | - A long-awaited feature has been implemented at last: | |
1253 | The local caching of CRLs fetched via HTTP or LDAP, activated | |
1254 | by the parameter cachecrls=yes in the config setup section | |
1255 | of ipsec.conf. The dynamically fetched CRLs are stored under | |
1256 | a unique file name containing the issuer's subjectKeyID | |
1257 | in /etc/ipsec.d/crls. | |
1258 | ||
1259 | - Applied a one-line patch courtesy of Michael Richardson | |
1260 | from the Openswan project which fixes the kernel-oops | |
1261 | in KLIPS when an snmp daemon is running on the same box. | |
1262 | ||
1263 | ||
1264 | strongswan-2.4.4 | |
1265 | ---------------- | |
1266 | ||
1267 | - Eliminated null length CRL distribution point strings. | |
1268 | ||
1269 | - Fixed a trust path evaluation bug introduced with 2.4.3 | |
1270 | ||
1271 | ||
1272 | strongswan-2.4.3 | |
1273 | ---------------- | |
1274 | ||
1275 | - Improved the joint OCSP / CRL revocation policy. | |
1276 | OCSP responses have precedence over CRL entries. | |
1277 | ||
1278 | - Introduced support of CRLv2 reason codes. | |
1279 | ||
1280 | - Fixed a bug with key-pad equipped readers which caused | |
1281 | pluto to prompt for the pin via the console when the first | |
1282 | occasion to enter the pin via the key-pad was missed. | |
1283 | ||
1284 | - When pluto is built with LDAP_V3 enabled, the library | |
1285 | liblber required by newer versions of openldap is now | |
1286 | included. | |
1287 | ||
1288 | ||
1289 | strongswan-2.4.2 | |
1290 | ---------------- | |
1291 | ||
1292 | - Added the _updown_espmark template which requires all | |
1293 | incoming ESP traffic to be marked with a default mark | |
1294 | value of 50. | |
1295 | ||
1296 | - Introduced the pkcs11keepstate parameter in the config setup | |
1297 | section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11 | |
1298 | session and login states are kept as long as possible during | |
1299 | the lifetime of pluto. This means that a PIN entry via a key | |
1300 | pad has to be done only once. | |
1301 | ||
1302 | - Introduced the pkcs11module parameter in the config setup | |
1303 | section of ipsec.conf which specifies the PKCS#11 module | |
1304 | to be used with smart cards. Example: | |
1305 | ||
1306 | pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo | |
1307 | ||
1308 | - Added support of smartcard readers equipped with a PIN pad. | |
1309 | ||
1310 | - Added patch by Jay Pfeifer which detects when netkey | |
1311 | modules have been statically built into the Linux 2.6 kernel. | |
1312 | ||
1313 | - Added two patches by Herbert Xu. The first uses ip xfrm | |
1314 | instead of setkey to flush the IPsec policy database. The | |
1315 | second sets the optional flag in inbound IPComp SAs only. | |
1316 | ||
1317 | - Applied Ulrich Weber's patch which fixes an interoperability | |
1318 | problem between native IPsec and KLIPS systems caused by | |
1319 | setting the replay window to 32 instead of 0 for ipcomp. | |
1320 | ||
1321 | ||
1322 | strongswan-2.4.1 | |
1323 | ---------------- | |
1324 | ||
1325 | - Fixed a bug which caused an unwanted Mode Config request | |
1326 | to be initiated in the case where "right" was used to denote | |
1327 | the local side in ipsec.conf and "left" the remote side, | |
1328 | contrary to the recommendation that "right" be remote and | |
1329 | "left" be"local". | |
1330 | ||
1331 | ||
1332 | strongswan-2.4.0a | |
1333 | ----------------- | |
1334 | ||
1335 | - updated Vendor ID to strongSwan-2.4.0 | |
1336 | ||
1337 | - updated copyright statement to include David Buechi and | |
1338 | Michael Meier | |
1339 | ||
1340 | ||
1341 | strongswan-2.4.0 | |
1342 | ---------------- | |
1343 | ||
1344 | - strongSwan now communicates with attached smartcards and | |
1345 | USB crypto tokens via the standardized PKCS #11 interface. | |
1346 | By default the OpenSC library from www.opensc.org is used | |
1347 | but any other PKCS#11 library could be dynamically linked. | |
1348 | strongSwan's PKCS#11 API was implemented by David Buechi | |
1349 | and Michael Meier, both graduates of the Zurich University | |
1350 | of Applied Sciences in Winterthur, Switzerland. | |
1351 | ||
1352 | - When a %trap eroute is triggered by an outgoing IP packet | |
1353 | then the native IPsec stack of the Linux 2.6 kernel [often/ | |
1354 | always?] returns an XFRM_ACQUIRE message with an undefined | |
1355 | protocol family field and the connection setup fails. | |
1356 | As a workaround IPv4 (AF_INET) is now assumed. | |
1357 | ||
1358 | - the results of the UML test scenarios are now enhanced | |
1359 | with block diagrams of the virtual network topology used | |
1360 | in a particular test. | |
1361 | ||
1362 | ||
1363 | strongswan-2.3.2 | |
1364 | ---------------- | |
1365 | ||
1366 | - fixed IV used to decrypt informational messages. | |
1367 | This bug was introduced with Mode Config functionality. | |
1368 | ||
1369 | - fixed NCP Vendor ID. | |
1370 | ||
1371 | - undid one of Ulrich Weber's maximum udp size patches | |
1372 | because it caused a segmentation fault with NAT-ed | |
1373 | Delete SA messages. | |
1374 | ||
1375 | - added UML scenarios wildcards and attr-cert which | |
1376 | demonstrate the implementation of IPsec policies based | |
1377 | on wildcard parameters contained in Distinguished Names and | |
1378 | on X.509 attribute certificates, respectively. | |
1379 | ||
1380 | ||
1381 | strongswan-2.3.1 | |
1382 | ---------------- | |
1383 | ||
1384 | - Added basic Mode Config functionality | |
1385 | ||
1386 | - Added Mathieu Lafon's patch which upgrades the status of | |
1387 | the NAT-Traversal implementation to RFC 3947. | |
1388 | ||
1389 | - The _startklips script now also loads the xfrm4_tunnel | |
1390 | module. | |
1391 | ||
1392 | - Added Ulrich Weber's netlink replay window size and | |
1393 | maximum udp size patches. | |
1394 | ||
1395 | - UML testing now uses the Linux 2.6.10 UML kernel by default. | |
1396 | ||
1397 | ||
1398 | strongswan-2.3.0 | |
1399 | ---------------- | |
1400 | ||
1401 | - Eric Marchionni and Patrik Rayo, both recent graduates from | |
1402 | the Zuercher Hochschule Winterthur in Switzerland, created a | |
1403 | User-Mode-Linux test setup for strongSwan. For more details | |
1404 | please read the INSTALL and README documents in the testing | |
1405 | subdirectory. | |
1406 | ||
1407 | - Full support of group attributes based on X.509 attribute | |
1408 | certificates. Attribute certificates can be generated | |
1409 | using the openac facility. For more details see | |
1410 | ||
1411 | man ipsec_openac. | |
1412 | ||
1413 | The group attributes can be used in connection definitions | |
1414 | in order to give IPsec access to specific user groups. | |
1415 | This is done with the new parameter left|rightgroups as in | |
1416 | ||
1417 | rightgroups="Research, Sales" | |
1418 | ||
1419 | giving access to users possessing the group attributes | |
1420 | Research or Sales, only. | |
1421 | ||
1422 | - In Quick Mode clients with subnet mask /32 are now | |
1423 | coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should | |
1424 | fix rekeying problems with the SafeNet/SoftRemote and NCP | |
1425 | Secure Entry Clients. | |
1426 | ||
1427 | - Changed the defaults of the ikelifetime and keylife parameters | |
1428 | to 3h and 1h, respectively. The maximum allowable values are | |
1429 | now both set to 24 h. | |
1430 | ||
1431 | - Suppressed notification wars between two IPsec peers that | |
1432 | could e.g. be triggered by incorrect ISAKMP encryption. | |
1433 | ||
1434 | - Public RSA keys can now have identical IDs if either the | |
1435 | issuing CA or the serial number is different. The serial | |
1436 | number of a certificate is now shown by the command | |
1437 | ||
1438 | ipsec auto --listpubkeys | |
1439 | ||
1440 | ||
1441 | strongswan-2.2.2 | |
1442 | ---------------- | |
1443 | ||
1444 | - Added Tuomo Soini's sourceip feature which allows a strongSwan | |
1445 | roadwarrior to use a fixed Virtual IP (see README section 2.6) | |
1446 | and reduces the well-known four tunnel case on VPN gateways to | |
1447 | a single tunnel definition (see README section 2.4). | |
1448 | ||
1449 | - Fixed a bug occuring with NAT-Traversal enabled when the responder | |
1450 | suddenly turns initiator and the initiator cannot find a matching | |
1451 | connection because of the floated IKE port 4500. | |
1452 | ||
1453 | - Removed misleading ipsec verify command from barf. | |
1454 | ||
1455 | - Running under the native IP stack, ipsec --version now shows | |
1456 | the Linux kernel version (courtesy to the Openswan project). | |
1457 | ||
1458 | ||
1459 | strongswan-2.2.1 | |
1460 | ---------------- | |
1461 | ||
1462 | - Introduced the ipsec auto --listalgs monitoring command which lists | |
1463 | all currently registered IKE and ESP algorithms. | |
1464 | ||
1465 | - Fixed a bug in the ESP algorithm selection occuring when the strict flag | |
1466 | is set and the first proposed transform does not match. | |
1467 | ||
1468 | - Fixed another deadlock in the use of the lock_certs_and_keys() mutex, | |
1469 | occuring when a smartcard is present. | |
1470 | ||
1471 | - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event. | |
1472 | ||
1473 | - Fixed the printing of the notification names (null) | |
1474 | ||
1475 | - Applied another of Herbert Xu's Netlink patches. | |
1476 | ||
1477 | ||
1478 | strongswan-2.2.0 | |
1479 | ---------------- | |
1480 | ||
1481 | - Support of Dead Peer Detection. The connection parameter | |
1482 | ||
1483 | dpdaction=clear|hold | |
1484 | ||
1485 | activates DPD for the given connection. | |
1486 | ||
1487 | - The default Opportunistic Encryption (OE) policy groups are not | |
1488 | automatically included anymore. Those wishing to activate OE can include | |
1489 | the policy group with the following statement in ipsec.conf: | |
1490 | ||
1491 | include /etc/ipsec.d/examples/oe.conf | |
1492 | ||
1493 | The default for [right|left]rsasigkey is now set to %cert. | |
1494 | ||
1495 | - strongSwan now has a Vendor ID of its own which can be activated | |
1496 | using the compile option VENDORID | |
1497 | ||
1498 | - Applied Herbert Xu's patch which sets the compression algorithm correctly. | |
1499 | ||
1500 | - Applied Herbert Xu's patch fixing an ESPINUDP problem | |
1501 | ||
1502 | - Applied Herbert Xu's patch setting source/destination port numbers. | |
1503 | ||
1504 | - Reapplied one of Herbert Xu's NAT-Traversal patches which got | |
1505 | lost during the migration from SuperFreeS/WAN. | |
1506 | ||
1507 | - Fixed a deadlock in the use of the lock_certs_and_keys() mutex. | |
1508 | ||
1509 | - Fixed the unsharing of alg parameters when instantiating group | |
1510 | connection. | |
1511 | ||
1512 | ||
1513 | strongswan-2.1.5 | |
1514 | ---------------- | |
1515 | ||
1516 | - Thomas Walpuski made me aware of a potential DoS attack via | |
1517 | a PKCS#7-wrapped certificate bundle which could overwrite valid CA | |
1518 | certificates in Pluto's authority certificate store. This vulnerability | |
1519 | was fixed by establishing trust in CA candidate certificates up to a | |
1520 | trusted root CA prior to insertion into Pluto's chained list. | |
1521 | ||
1522 | - replaced the --assign option by the -v option in the auto awk script | |
1523 | in order to make it run with mawk under debian/woody. | |
1524 | ||
1525 | ||
1526 | strongswan-2.1.4 | |
1527 | ---------------- | |
1528 | ||
1529 | - Split of the status information between ipsec auto --status (concise) | |
1530 | and ipsec auto --statusall (verbose). Both commands can be used with | |
1531 | an optional connection selector: | |
1532 | ||
1533 | ipsec auto --status[all] <connection_name> | |
1534 | ||
1535 | - Added the description of X.509 related features to the ipsec_auto(8) | |
1536 | man page. | |
1537 | ||
1538 | - Hardened the ASN.1 parser in debug mode, especially the printing | |
1539 | of malformed distinguished names. | |
1540 | ||
1541 | - The size of an RSA public key received in a certificate is now restricted to | |
1542 | ||
1543 | 512 bits <= modulus length <= 8192 bits. | |
1544 | ||
1545 | - Fixed the debug mode enumeration. | |
1546 | ||
1547 | ||
1548 | strongswan-2.1.3 | |
1549 | ---------------- | |
1550 | ||
1551 | - Fixed another PKCS#7 vulnerability which could lead to an | |
1552 | endless loop while following the X.509 trust chain. | |
1553 | ||
1554 | ||
1555 | strongswan-2.1.2 | |
1556 | ---------------- | |
1557 | ||
1558 | - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski | |
1559 | that accepted end certificates having identical issuer and subject | |
1560 | distinguished names in a multi-tier X.509 trust chain. | |
1561 | ||
1562 | ||
1563 | strongswan-2.1.1 | |
1564 | ---------------- | |
1565 | ||
1566 | - Removed all remaining references to ipsec_netlink.h in KLIPS. | |
1567 | ||
1568 | ||
1569 | strongswan-2.1.0 | |
1570 | ---------------- | |
1571 | ||
1572 | - The new "ca" section allows to define the following parameters: | |
1573 | ||
1574 | ca kool | |
1575 | cacert=koolCA.pem # cacert of kool CA | |
1576 | ocspuri=http://ocsp.kool.net:8001 # ocsp server | |
1577 | ldapserver=ldap.kool.net # default ldap server | |
1578 | crluri=http://www.kool.net/kool.crl # crl distribution point | |
1579 | crluri2="ldap:///O=Kool, C= .." # crl distribution point #2 | |
1580 | auto=add # add, ignore | |
1581 | ||
1582 | The ca definitions can be monitored via the command | |
1583 | ||
1584 | ipsec auto --listcainfos | |
1585 | ||
1586 | - Fixed cosmetic corruption of /proc filesystem by integrating | |
1587 | D. Hugh Redelmeier's freeswan-2.06 kernel fixes. | |
1588 | ||
1589 | ||
1590 | strongswan-2.0.2 | |
1591 | ---------------- | |
1592 | ||
1593 | - Added support for the 818043 NAT-Traversal update of Microsoft's | |
1594 | Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode. | |
1595 | ||
1596 | - A symbolic link to libcrypto is now added in the kernel sources | |
1597 | during kernel compilation | |
1598 | ||
1599 | - Fixed a couple of 64 bit issues (mostly casts to int). | |
1600 | Thanks to Ken Bantoft who checked my sources on a 64 bit platform. | |
1601 | ||
1602 | - Replaced s[n]printf() statements in the kernel by ipsec_snprintf(). | |
1603 | Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro | |
1604 | of the FreeS/WAN team who solved this problem with the 2.4.25 kernel. | |
1605 | ||
1606 | ||
1607 | strongswan-2.0.1 | |
1608 | ---------------- | |
1609 | ||
1610 | - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName | |
1611 | certificate extension which contains no generalName item) can cause | |
1612 | a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has | |
1613 | been hardened to make it more robust against malformed ASN.1 objects. | |
1614 | ||
1615 | - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native | |
1616 | Linux 2.6 IPsec stack. | |
1617 | ||
1618 | ||
1619 | strongswan-2.0.0 | |
1620 | ---------------- | |
1621 | ||
1622 | - based on freeswan-2.04, x509-1.5.3, nat-0.6c, alg-0.8.1rc12 |
