1 | strongswan-4.3.5 |
2 | ---------------- | |
3 | ||
628f023d AS |
4 | - The IKEv1 pluto daemon can now use SQL-based address pools to deal out |
5 | virtual IP addresses as a Mode Config server. The pool capability has been | |
6 | migrated from charon's sql plugin to a new attr-sql plugin which is loaded | |
b42bfc79 | 7 | by libstrongswan and which can be used by both daemons either with a SQLite |
628f023d AS |
8 | or MySQL database and the corresponding plugin. |
9 | ||
b42bfc79 MW |
10 | - Plugin names have been streamlined: EAP plugins now have a dash after eap |
11 | (e.g. eap-sim), as it is used with the --enable-eap-sim ./configure option. | |
12 | Plugin configuration sections in strongswan.conf now use the same name as the | |
13 | plugin itself (i.e. with a dash). Make sure to update "load" directives and | |
14 | the affected plugin sections in existing strongswan.conf files. | |
15 | ||
d245f5cf AS |
16 | - The private/public key parsing and encoding has been split up into |
17 | separate pkcs1, pgp, pem and dnskey plugins. The public key implementation | |
18 | plugins gmp, gcrypt and openssl can all make use of them. | |
b6b90b68 | 19 | |
55b045ab MW |
20 | - The EAP-AKA plugin can use different backends for USIM/quintuplet |
21 | calculations, very similar to the EAP-SIM plugin. The existing 3GPP2 software | |
22 | implementation has been migrated to a separate plugin. | |
23 | ||
d245f5cf | 24 | - The IKEv2 daemon charon gained basic PGP support. It can use locally installed |
b6b90b68 MW |
25 | peer certificates and can issue signatures based on RSA private keys. |
26 | ||
27 | - The new 'ipsec pki' tool provides a set of commands to maintain a public | |
28 | key infrastructure. It currently supports operations to create RSA and ECDSA | |
29 | private/public keys, calculate fingerprints and issue or verify certificates. | |
30 | ||
31 | - Charon uses a monotonic time source for statistics and job queueing, behaving | |
32 | correctly if the system time changes (e.g. when using NTP). | |
33 | ||
34 | - In addition to time based rekeying, charon supports IPsec SA lifetimes based | |
35 | on processed volume or number of packets. They new ipsec.conf paramaters | |
36 | 'lifetime' (an alias to 'keylife'), 'lifebytes' and 'lifepackets' handle | |
37 | SA timeouts, while the parameters 'margintime' (an alias to rekeymargin), | |
38 | 'marginbytes' and 'marginpackets' trigger the rekeying before a SA expires. | |
39 | The existing parameter 'rekeyfuzz' affects all margins. | |
40 | ||
85af7a89 MW |
41 | - If no CA/Gateway certificate is specified in the NetworkManager plugin, |
42 | charon uses a set of trusted root certificates preinstalled by distributions. | |
43 | The directory containing CA certificates can be specified using the | |
44 | --with-nm-ca-dir=path configure option. | |
45 | ||
b80fa9ca | 46 | - Fixed the encoding of the Email relative distinguished name in left|rightid |
509f70c1 | 47 | statements. |
b80fa9ca | 48 | |
509f70c1 AS |
49 | - Fixed the broken parsing of PKCS#7 wrapped certificates by the pluto daemon. |
50 | ||
51 | - Fixed smartcard-based authentication in the pluto daemon which was broken by | |
52 | the ECDSA support introduced with the 4.3.2 release. | |
53 | ||
54 | - The pluto daemon now uses the libstrongswan x509 plugin for certificates and | |
55 | CRls and the struct id type was replaced by identification_t used by charon | |
56 | and the libstrongswan library. | |

59 | strongswan-4.3.4 |
60 | ---------------- | |
61 | ||
62 | - IKEv2 charon daemon ported to FreeBSD and Mac OS X. Installation details can | |
63 | be found on wiki.strongswan.org. | |
64 | ||
65 | - ipsec statusall shows the number of bytes transmitted and received over | |
66 | ESP connections configured by the IKEv2 charon daemon. | |
67 | ||
68 | - The IKEv2 charon daemon supports include files in ipsec.secrets. | |
69 | ||
70 | ||
1c7f456a AS |
71 | strongswan-4.3.3 |
72 | ---------------- | |
73 | ||
aa74d705 AS |
74 | - The configuration option --enable-integrity-test plus the strongswan.conf |
75 | option libstrongswan.integrity_test = yes activate integrity tests | |
76 | of the IKE daemons charon and pluto, libstrongswan and all loaded | |
77 | plugins. Thus dynamic library misconfigurations and non-malicious file | |
78 | manipulations can be reliably detected. | |
79 | ||
1c7f456a AS |
80 | - The new default setting libstrongswan.ecp_x_coordinate_only=yes allows |
81 | IKEv1 interoperability with MS Windows using the ECP DH groups 19 and 20. | |
82 | ||
83 | - The IKEv1 pluto daemon now supports the AES-CCM and AES-GCM ESP | |
84 | authenticated encryption algorithms. | |
85 | ||
aa74d705 AS |
86 | - The IKEv1 pluto daemon now supports V4 OpenPGP keys. |
87 | ||
88 | - The RDN parser vulnerability discovered by Orange Labs research team | |
89 | was not completely fixed in version 4.3.2. Some more modifications | |
90 | had to be applied to the asn1_length() function to make it robust. | |
91 | ||
1c7f456a | 92 | |
80c0710c MW |
93 | strongswan-4.3.2 |
94 | ---------------- | |
95 | ||
96 | - The new gcrypt plugin provides symmetric cipher, hasher, RNG, Diffie-Hellman | |
97 | and RSA crypto primitives using the LGPL licensed GNU gcrypt library. | |
98 | ||
99 | - libstrongswan features an integrated crypto selftest framework for registered | |
100 | algorithms. The test-vector plugin provides a first set of test vectors and | |
101 | allows pluto and charon to rely on tested crypto algorithms. | |
102 | ||
b32af120 AS |
103 | - pluto can now use all libstrongswan plugins with the exception of x509 and xcbc. |
104 | Thanks to the openssl plugin, the ECP Diffie-Hellman groups 19, 20, 21, 25, and | |
105 | 26 as well as ECDSA-256, ECDSA-384, and ECDSA-521 authentication can be used | |
106 | with IKEv1. | |
126f2130 AS |
107 | |
108 | - Applying their fuzzing tool, the Orange Labs vulnerability research team found | |
109 | another two DoS vulnerabilities, one in the rather old ASN.1 parser of Relative | |
110 | Distinguished Names (RDNs) and a second one in the conversion of ASN.1 UTCTIME | |
111 | and GENERALIZEDTIME strings to a time_t value. | |

3bf7c249 MW |
114 | strongswan-4.3.1 |
115 | ---------------- | |
116 | ||
117 | - The nm plugin now passes DNS/NBNS server information to NetworkManager, | |
09dbca9f | 118 | allowing a gateway administrator to set DNS/NBNS configuration on clients |
3bf7c249 MW |
119 | dynamically. |
120 | ||
09dbca9f MW |
121 | - The nm plugin also accepts CA certificates for gateway authentication. If |
122 | a CA certificate is configured, strongSwan uses the entered gateway address | |
123 | as its idenitity, requiring the gateways certificate to contain the same as | |
124 | subjectAltName. This allows a gateway administrator to deploy the same | |
125 | certificates to Windows 7 and NetworkManager clients. | |
047b2e42 | 126 | |
050cc582 AS |
127 | - The command ipsec purgeike deletes IKEv2 SAs that don't have a CHILD SA. |
128 | The command ipsec down <conn>{n} deletes CHILD SA instance n of connection | |
129 | <conn> whereas ipsec down <conn>{*} deletes all CHILD SA instances. | |
130 | The command ipsec down <conn>[n] deletes IKE SA instance n of connection | |
131 | <conn> plus dependent CHILD SAs whereas ipsec down <conn>[*] deletes all | |
132 | IKE SA instances of connection <conn>. | |
133 | ||
09dbca9f | 134 | - Fixed a regression introduced in 4.3.0 where EAP authentication calculated |
047b2e42 MW |
135 | the AUTH payload incorrectly. Further, the EAP-MSCHAPv2 MSK key derivation |
136 | has been updated to be compatible with the Windows 7 Release Candidate. | |
137 | ||
138 | - Refactored installation of triggering policies. Routed policies are handled | |
139 | outside of IKE_SAs to keep them installed in any case. A tunnel gets | |
140 | established only once, even if initiation is delayed due network outages. | |
141 | ||
050cc582 AS |
142 | - Improved the handling of multiple acquire signals triggered by the kernel. |
143 | ||
144 | - Fixed two DoS vulnerabilities in the charon daemon that were discovered by | |
145 | fuzzing techniques: 1) Sending a malformed IKE_SA_INIT request leaved an | |
146 | incomplete state which caused a null pointer dereference if a subsequent | |
147 | CREATE_CHILD_SA request was sent. 2) Sending an IKE_AUTH request with either | |
148 | a missing TSi or TSr payload caused a null pointer derefence because the | |
b6b90b68 | 149 | checks for TSi and TSr were interchanged. The IKEv2 fuzzer used was |
050cc582 AS |
150 | developped by the Orange Labs vulnerability research team. The tool was |
151 | initially written by Gabriel Campana and is now maintained by Laurent Butti. | |
152 | ||
047b2e42 MW |
153 | - Added support for AES counter mode in ESP in IKEv2 using the proposal |
154 | keywords aes128ctr, aes192ctr and aes256ctr. | |
155 | ||
d44fd821 | 156 | - Further progress in refactoring pluto: Use of the curl and ldap plugins |
050cc582 AS |
157 | for fetching crls and OCSP. Use of the random plugin to get keying material |
158 | from /dev/random or /dev/urandom. Use of the openssl plugin as an alternative | |
d44fd821 | 159 | to the aes, des, sha1, sha2, and md5 plugins. The blowfish, twofish, and |
050cc582 | 160 | serpent encryption plugins are now optional and are not enabled by default. |
d44fd821 AS |

163 | strongswan-4.3.0 |
164 | ---------------- | |
165 | ||
81fc8e5f MW |
166 | - Support for the IKEv2 Multiple Authentication Exchanges extension (RFC4739). |
167 | Initiators and responders can use several authentication rounds (e.g. RSA | |
168 | followed by EAP) to authenticate. The new ipsec.conf leftauth/rightauth and | |
169 | leftauth2/rightauth2 parameters define own authentication rounds or setup | |
170 | constraints for the remote peer. See the ipsec.conf man page for more detials. | |
171 | ||
172 | - If glibc printf hooks (register_printf_function) are not available, | |
173 | strongSwan can use the vstr string library to run on non-glibc systems. | |
174 | ||
558c89e7 AS |
175 | - The IKEv2 charon daemon can now configure the ESP CAMELLIA-CBC cipher |
176 | (esp=camellia128|192|256). | |
247e665a | 177 | |
558c89e7 AS |
178 | - Refactored the pluto and scepclient code to use basic functions (memory |
179 | allocation, leak detective, chunk handling, printf_hooks, strongswan.conf | |
180 | attributes, ASN.1 parser, etc.) from the libstrongswan library. | |
b752f873 | 181 | |
558c89e7 AS |
182 | - Up to two DNS and WINS servers to be sent via IKEv1 ModeConfig can be |
183 | configured in the pluto section of strongswan.conf. | |

186 | strongswan-4.2.14 |
187 | ----------------- | |
188 | ||
22180558 AS |
189 | - The new server-side EAP RADIUS plugin (--enable-eap-radius) |
190 | relays EAP messages to and from a RADIUS server. Succesfully | |
191 | tested with with a freeradius server using EAP-MD5 and EAP-SIM. | |
192 | ||
79b27294 AS |
193 | - A vulnerability in the Dead Peer Detection (RFC 3706) code was found by |
194 | Gerd v. Egidy <gerd.von.egidy@intra2net.com> of Intra2net AG affecting | |
195 | all Openswan and strongSwan releases. A malicious (or expired ISAKMP) | |
196 | R_U_THERE or R_U_THERE_ACK Dead Peer Detection packet can cause the | |
197 | pluto IKE daemon to crash and restart. No authentication or encryption | |
198 | is required to trigger this bug. One spoofed UDP packet can cause the | |
199 | pluto IKE daemon to restart and be unresponsive for a few seconds while | |
200 | restarting. This DPD null state vulnerability has been officially | |
201 | registered as CVE-2009-0790 and is fixed by this release. | |
202 | ||
22180558 AS |
203 | - ASN.1 to time_t conversion caused a time wrap-around for |
204 | dates after Jan 18 03:14:07 UTC 2038 on 32-bit platforms. | |
205 | As a workaround such dates are set to the maximum representable | |
206 | time, i.e. Jan 19 03:14:07 UTC 2038. | |
207 | ||
208 | - Distinguished Names containing wildcards (*) are not sent in the | |
b6b90b68 | 209 | IDr payload anymore. |
623bca40 AS |
210 | |
211 | ||
076e7853 AS |
212 | strongswan-4.2.13 |
213 | ----------------- | |
214 | ||
215 | - Fixed a use-after-free bug in the DPD timeout section of the | |
216 | IKEv1 pluto daemon which sporadically caused a segfault. | |
217 | ||
218 | - Fixed a crash in the IKEv2 charon daemon occuring with | |
b6b90b68 | 219 | mixed RAM-based and SQL-based virtual IP address pools. |
076e7853 | 220 | |
f15483ef AS |
221 | - Fixed ASN.1 parsing of algorithmIdentifier objects where the |
222 | parameters field is optional. | |
223 | ||
03991bc1 MW |
224 | - Ported nm plugin to NetworkManager 7.1. |
225 | ||
076e7853 | 226 | |
bfde75ee | 227 | strongswan-4.2.12 |
076e7853 | 228 | ----------------- |
bfde75ee AS |
229 | |
230 | - Support of the EAP-MSCHAPv2 protocol enabled by the option | |
231 | --enable-eap-mschapv2. Requires the MD4 hash algorithm enabled | |
232 | either by --enable-md4 or --enable-openssl. | |
233 | ||
234 | - Assignment of up to two DNS and up to two WINS servers to peers via | |
b6b90b68 | 235 | the IKEv2 Configuration Payload (CP). The IPv4 or IPv6 nameserver |
bfde75ee AS |
236 | addresses are defined in strongswan.conf. |
237 | ||
238 | - The strongSwan applet for the Gnome NetworkManager is now built and | |
239 | distributed as a separate tarball under the name NetworkManager-strongswan. | |
240 | ||
b6b90b68 | 241 | |
0519ca90 AS |
242 | strongswan-4.2.11 |
243 | ----------------- | |
244 | ||
ae1ae574 AS |
245 | - Fixed ESP NULL encryption broken by the refactoring of keymat.c. |
246 | Also introduced proper initialization and disposal of keying material. | |
247 | ||
248 | - Fixed the missing listing of connection definitions in ipsec statusall | |
249 | broken by an unfortunate local variable overload. | |
0519ca90 AS |
250 | |
251 | ||
4856241c MW |
252 | strongswan-4.2.10 |
253 | ----------------- | |
254 | ||
255 | - Several performance improvements to handle thousands of tunnels with almost | |
256 | linear upscaling. All relevant data structures have been replaced by faster | |
257 | counterparts with better lookup times. | |
258 | ||
259 | - Better parallelization to run charon on multiple cores. Due to improved | |
260 | ressource locking and other optimizations the daemon can take full | |
261 | advantage of 16 or even more cores. | |
262 | ||
263 | - The load-tester plugin can use a NULL Diffie-Hellman group and simulate | |
264 | unique identities and certificates by signing peer certificates using a CA | |
265 | on the fly. | |
266 | ||
267 | - The redesigned stroke in-memory IP pool handles leases. The "ipsec leases" | |
268 | command queries assigned leases. | |
269 | ||
270 | - Added support for smartcards in charon by using the ENGINE API provided by | |
271 | OpenSSL, based on patches by Michael Roßberg. | |
272 | ||
273 | - The Padlock plugin supports the hardware RNG found on VIA CPUs to provide a | |
274 | reliable source of randomness. | |
275 | ||
73937bd8 MW |
276 | strongswan-4.2.9 |
277 | ---------------- | |
278 | ||
509e07c5 AS |
279 | - Flexible configuration of logging subsystem allowing to log to multiple |
280 | syslog facilities or to files using fine-grained log levels for each target. | |
73937bd8 MW |
281 | |
282 | - Load testing plugin to do stress testing of the IKEv2 daemon against self | |
283 | or another host. Found and fixed issues during tests in the multi-threaded | |
284 | use of the OpenSSL plugin. | |
285 | ||
286 | - Added profiling code to synchronization primitives to find bottlenecks if | |
7bdc931e | 287 | running on multiple cores. Found and fixed an issue where parts of the |
73937bd8 MW |
288 | Diffie-Hellman calculation acquired an exclusive lock. This greatly improves |
289 | parallelization to multiple cores. | |
290 | ||
509e07c5 AS |
291 | - updown script invocation has been separated into a plugin of its own to |
292 | further slim down the daemon core. | |
73937bd8 | 293 | |
509e07c5 | 294 | - Separated IKE_SA/CHILD_SA key derivation process into a closed system, |
7bdc931e | 295 | allowing future implementations to use a secured environment in e.g. kernel |
73937bd8 MW |
296 | memory or hardware. |
297 | ||
509e07c5 AS |
298 | - The kernel interface of charon has been modularized. XFRM NETLINK (default) |
299 | and PFKEY (--enable-kernel-pfkey) interface plugins for the native IPsec | |
300 | stack of the Linux 2.6 kernel as well as a PFKEY interface for the KLIPS | |
301 | IPsec stack (--enable-kernel-klips) are provided. | |
302 | ||
303 | - Basic Mobile IPv6 support has been introduced, securing Binding Update | |
304 | messages as well as tunneled traffic between Mobile Node and Home Agent. | |
305 | The installpolicy=no option allows peaceful cooperation with a dominant | |
306 | mip6d daemon and the new type=transport_proxy implements the special MIPv6 | |
307 | IPsec transport proxy mode where the IKEv2 daemon uses the Care-of-Address | |
308 | but the IPsec SA is set up for the Home Adress. | |
7bdc931e | 309 | |
4dc0dce8 AS |
310 | - Implemented migration of Mobile IPv6 connections using the KMADDRESS |
311 | field contained in XFRM_MSG_MIGRATE messages sent by the mip6d daemon | |
312 | via the Linux 2.6.28 (or appropriately patched) kernel. | |
313 | ||
73937bd8 | 314 | |
e39b271b AS |
315 | strongswan-4.2.8 |
316 | ---------------- | |
317 | ||
5dadb16e | 318 | - IKEv2 charon daemon supports authentication based on raw public keys |
e39b271b AS |
319 | stored in the SQL database backend. The ipsec listpubkeys command |
320 | lists the available raw public keys via the stroke interface. | |
321 | ||
4f0241e6 MW |
322 | - Several MOBIKE improvements: Detect changes in NAT mappings in DPD exchanges, |
323 | handle events if kernel detects NAT mapping changes in UDP-encapsulated | |
324 | ESP packets (requires kernel patch), reuse old addesses in MOBIKE updates as | |
325 | long as possible and other fixes. | |
326 | ||
5dadb16e AS |
327 | - Fixed a bug in addr_in_subnet() which caused insertion of wrong source |
328 | routes for destination subnets having netwmasks not being a multiple of 8 bits. | |
329 | Thanks go to Wolfgang Steudel, TU Ilmenau for reporting this bug. | |
330 | ||
e39b271b | 331 | |
e376d75f MW |
332 | strongswan-4.2.7 |
333 | ---------------- | |
334 | ||
b37cda82 AS |
335 | - Fixed a Denial-of-Service vulnerability where an IKE_SA_INIT message with |
336 | a KE payload containing zeroes only can cause a crash of the IKEv2 charon | |
337 | daemon due to a NULL pointer returned by the mpz_export() function of the | |
338 | GNU Multiprecision Library (GMP). Thanks go to Mu Dynamics Research Labs | |
b6b90b68 | 339 | for making us aware of this problem. |
b37cda82 | 340 | |
b6b90b68 | 341 | - The new agent plugin provides a private key implementation on top of an |
e376d75f MW |
342 | ssh-agent. |
343 | ||
344 | - The NetworkManager plugin has been extended to support certificate client | |
b1f47854 | 345 | authentication using RSA keys loaded from a file or using ssh-agent. |
e376d75f MW |
346 | |
347 | - Daemon capability dropping has been ported to libcap and must be enabled | |
348 | explicitly --with-capabilities=libcap. Future version will support the | |
349 | newer libcap2 library. | |
350 | ||
b37cda82 AS |
351 | - ipsec listalgs lists the IKEv2 cryptografic algorithms registered with the |
352 | charon keying daemon. | |
353 | ||
354 | ||
9f9d6ece AS |
355 | strongswan-4.2.6 |
356 | ---------------- | |
357 | ||
609166f4 MW |
358 | - A NetworkManager plugin allows GUI-based configuration of road-warrior |
359 | clients in a simple way. It features X509 based gateway authentication | |
360 | and EAP client authentication, tunnel setup/teardown and storing passwords | |
361 | in the Gnome Keyring. | |
362 | ||
363 | - A new EAP-GTC plugin implements draft-sheffer-ikev2-gtc-00.txt and allows | |
364 | username/password authentication against any PAM service on the gateway. | |
b6b90b68 | 365 | The new EAP method interacts nicely with the NetworkManager plugin and allows |
609166f4 MW |
366 | client authentication against e.g. LDAP. |
367 | ||
368 | - Improved support for the EAP-Identity method. The new ipsec.conf eap_identity | |
369 | parameter defines an additional identity to pass to the server in EAP | |
370 | authentication. | |
371 | ||
9f9d6ece AS |
372 | - The "ipsec statusall" command now lists CA restrictions, EAP |
373 | authentication types and EAP identities. | |
374 | ||
375 | - Fixed two multithreading deadlocks occurring when starting up | |
376 | several hundred tunnels concurrently. | |
377 | ||
378 | - Fixed the --enable-integrity-test configure option which | |
379 | computes a SHA-1 checksum over the libstrongswan library. | |
380 | ||
381 | ||
174216c7 AS |
382 | strongswan-4.2.5 |
383 | ---------------- | |
384 | ||
b6b90b68 | 385 | - Consistent logging of IKE and CHILD SAs at the audit (AUD) level. |
8124e491 AS |
386 | |
387 | - Improved the performance of the SQL-based virtual IP address pool | |
388 | by introducing an additional addresses table. The leases table | |
389 | storing only history information has become optional and can be | |
390 | disabled by setting charon.plugins.sql.lease_history = no in | |
391 | strongswan.conf. | |
392 | ||
eb0cc338 | 393 | - The XFRM_STATE_AF_UNSPEC flag added to xfrm.h allows IPv4-over-IPv6 |
de5f70e7 | 394 | and IPv6-over-IPv4 tunnels with the 2.6.26 and later Linux kernels. |
eb0cc338 | 395 | |
174216c7 AS |
396 | - management of different virtual IP pools for different |
397 | network interfaces have become possible. | |
398 | ||
b6b90b68 | 399 | - fixed a bug which prevented the assignment of more than 256 |
174216c7 AS |
400 | virtual IP addresses from a pool managed by an sql database. |
401 | ||
8124e491 AS |
402 | - fixed a bug which did not delete own IPCOMP SAs in the kernel. |
403 | ||

179dd12c AS |
405 | strongswan-4.2.4 |
406 | ---------------- | |
407 | ||
9de95037 AS |
408 | - Added statistics functions to ipsec pool --status and ipsec pool --leases |
409 | and input validation checks to various ipsec pool commands. | |
179dd12c | 410 | |
73a8eed3 | 411 | - ipsec statusall now lists all loaded charon plugins and displays |
9de95037 | 412 | the negotiated IKEv2 cipher suite proposals. |
73a8eed3 AS |
413 | |
414 | - The openssl plugin supports the elliptic curve Diffie-Hellman groups | |
415 | 19, 20, 21, 25, and 26. | |
416 | ||
417 | - The openssl plugin supports ECDSA authentication using elliptic curve | |
418 | X.509 certificates. | |
419 | ||
420 | - Fixed a bug in stroke which caused multiple charon threads to close | |
421 | the file descriptors during packet transfers over the stroke socket. | |
b6b90b68 | 422 | |
e0bb4dbb AS |
423 | - ESP sequence numbers are now migrated in IPsec SA updates handled by |
424 | MOBIKE. Works only with Linux kernels >= 2.6.17. | |
425 | ||
179dd12c | 426 | |
83d9e870 AS |
427 | strongswan-4.2.3 |
428 | ---------------- | |
429 | ||
b6b90b68 | 430 | - Fixed the strongswan.conf path configuration problem that occurred when |
83d9e870 AS |
431 | --sysconfig was not set explicitly in ./configure. |
432 | ||
433 | - Fixed a number of minor bugs that where discovered during the 4th | |
434 | IKEv2 interoperability workshop in San Antonio, TX. | |
435 | ||
436 | ||
7f491111 MW |
437 | strongswan-4.2.2 |
438 | ---------------- | |
439 | ||
a57cd446 AS |
440 | - Plugins for libstrongswan and charon can optionally be loaded according |
441 | to a configuration in strongswan.conf. Most components provide a | |
7f491111 | 442 | "load = " option followed by a space separated list of plugins to load. |
a57cd446 AS |
443 | This allows e.g. the fallback from a hardware crypto accelerator to |
444 | to software-based crypto plugins. | |
7f491111 MW |
445 | |
446 | - Charons SQL plugin has been extended by a virtual IP address pool. | |
a57cd446 AS |
447 | Configurations with a rightsourceip=%poolname setting query a SQLite or |
448 | MySQL database for leases. The "ipsec pool" command helps in administrating | |
449 | the pool database. See ipsec pool --help for the available options | |
450 | ||
451 | - The Authenticated Encryption Algorithms AES-CCM-8/12/16 and AES-GCM-8/12/16 | |
b6b90b68 | 452 | for ESP are now supported starting with the Linux 2.6.25 kernel. The |
a57cd446 AS |
453 | syntax is e.g. esp=aes128ccm12 or esp=aes256gcm16. |
454 | ||
7f491111 | 455 | |
5c5d67d6 AS |
456 | strongswan-4.2.1 |
457 | ---------------- | |
458 | ||
c306dfb1 | 459 | - Support for "Hash and URL" encoded certificate payloads has been implemented |
b1f8fc0c TB |
460 | in the IKEv2 daemon charon. Using the "certuribase" option of a CA section |
461 | allows to assign a base URL to all certificates issued by the specified CA. | |
462 | The final URL is then built by concatenating that base and the hex encoded | |
463 | SHA1 hash of the DER encoded certificate. Note that this feature is disabled | |
464 | by default and must be enabled using the option "charon.hash_and_url". | |
5c5d67d6 | 465 | |
58caabf7 MW |
466 | - The IKEv2 daemon charon now supports the "uniqueids" option to close multiple |
467 | IKE_SAs with the same peer. The option value "keep" prefers existing | |
468 | connection setups over new ones, where the value "replace" replaces existing | |
469 | connections. | |
b6b90b68 MW |
470 | |
471 | - The crypto factory in libstrongswan additionaly supports random number | |
58caabf7 | 472 | generators, plugins may provide other sources of randomness. The default |
c306dfb1 | 473 | plugin reads raw random data from /dev/(u)random. |
58caabf7 | 474 | |
b6b90b68 | 475 | - Extended the credential framework by a caching option to allow plugins |
58caabf7 | 476 | persistent caching of fetched credentials. The "cachecrl" option has been |
c306dfb1 | 477 | re-implemented. |
58caabf7 MW |
478 | |
479 | - The new trustchain verification introduced in 4.2.0 has been parallelized. | |
480 | Threads fetching CRL or OCSP information no longer block other threads. | |
5c5d67d6 | 481 | |
58caabf7 MW |
482 | - A new IKEv2 configuration attribute framework has been introduced allowing |
483 | plugins to provide virtual IP addresses, and in the future, other | |
484 | configuration attribute services (e.g. DNS/WINS servers). | |
5c5d67d6 | 485 | |
466abb49 | 486 | - The stroke plugin has been extended to provide virtual IP addresses from |
58caabf7 MW |
487 | a pool defined in ipsec.conf. The "rightsourceip" parameter now accepts |
488 | address pools in CIDR notation (e.g. 10.1.1.0/24). The parameter also accepts | |
489 | the value "%poolname", where "poolname" identifies a pool provided by a | |
466abb49 | 490 | separate plugin. |
58caabf7 | 491 | |
c306dfb1 | 492 | - Fixed compilation on uClibc and a couple of other minor bugs. |
58caabf7 | 493 | |
c306dfb1 | 494 | - Set DPD defaults in ipsec starter to dpd_delay=30s and dpd_timeout=150s. |
466abb49 AS |
495 | |
496 | - The IKEv1 pluto daemon now supports the ESP encryption algorithm CAMELLIA | |
c306dfb1 | 497 | with key lengths of 128, 192, and 256 bits, as well as the authentication |
466abb49 AS |
498 | algorithm AES_XCBC_MAC. Configuration example: esp=camellia192-aesxcbc. |
499 | ||

a11ea97d AS |
501 | strongswan-4.2.0 |
502 | ---------------- | |
503 | ||
16f5dacd MW |
504 | - libstrongswan has been modularized to attach crypto algorithms, |
505 | credential implementations (keys, certificates) and fetchers dynamically | |
506 | through plugins. Existing code has been ported to plugins: | |
507 | - RSA/Diffie-Hellman implementation using the GNU Multi Precision library | |
508 | - X509 certificate system supporting CRLs, OCSP and attribute certificates | |
509 | - Multiple plugins providing crypto algorithms in software | |
510 | - CURL and OpenLDAP fetcher | |
a11ea97d | 511 | |
16f5dacd MW |
512 | - libstrongswan gained a relational database API which uses pluggable database |
513 | providers. Plugins for MySQL and SQLite are available. | |
514 | ||
515 | - The IKEv2 keying daemon charon is more extensible. Generic plugins may provide | |
516 | connection configuration, credentials and EAP methods or control the daemon. | |
517 | Existing code has been ported to plugins: | |
518 | - EAP-AKA, EAP-SIM, EAP-MD5 and EAP-Identity | |
519 | - stroke configuration, credential and control (compatible to pluto) | |
520 | - XML bases management protocol to control and query the daemon | |
521 | The following new plugins are available: | |
522 | - An experimental SQL configuration, credential and logging plugin on | |
523 | top of either MySQL or SQLite | |
524 | - A unit testing plugin to run tests at daemon startup | |
525 | ||
526 | - The authentication and credential framework in charon has been heavily | |
527 | refactored to support modular credential providers, proper | |
528 | CERTREQ/CERT payload exchanges and extensible authorization rules. | |
529 | ||
b6b90b68 | 530 | - The framework of strongSwan Manager has envolved to the web application |
16f5dacd MW |
531 | framework libfast (FastCGI Application Server w/ Templates) and is usable |
532 | by other applications. | |
b6b90b68 | 533 | |

535 | strongswan-4.1.11 |
536 | ----------------- | |
fb6d76cd | 537 | |
a561f74d AS |
538 | - IKE rekeying in NAT situations did not inherit the NAT conditions |
539 | to the rekeyed IKE_SA so that the UDP encapsulation was lost with | |
540 | the next CHILD_SA rekeying. | |
541 | ||
542 | - Wrong type definition of the next_payload variable in id_payload.c | |
b6b90b68 | 543 | caused an INVALID_SYNTAX error on PowerPC platforms. |
fb6d76cd | 544 | |
e6b50b3f AS |
545 | - Implemented IKEv2 EAP-SIM server and client test modules that use |
546 | triplets stored in a file. For details on the configuration see | |
547 | the scenario 'ikev2/rw-eap-sim-rsa'. | |
548 | ||
fb6d76cd | 549 | |
83e0d841 AS |
550 | strongswan-4.1.10 |
551 | ----------------- | |
552 | ||
553 | - Fixed error in the ordering of the certinfo_t records in the ocsp cache that | |
b6b90b68 | 554 | caused multiple entries of the same serial number to be created. |
83e0d841 | 555 | |
fdc7c943 MW |
556 | - Implementation of a simple EAP-MD5 module which provides CHAP |
557 | authentication. This may be interesting in conjunction with certificate | |
558 | based server authentication, as weak passwords can't be brute forced | |
559 | (in contradiction to traditional IKEv2 PSK). | |
560 | ||
561 | - A complete software based implementation of EAP-AKA, using algorithms | |
562 | specified in 3GPP2 (S.S0055). This implementation does not use an USIM, | |
563 | but reads the secrets from ipsec.secrets. Make sure to read eap_aka.h | |
564 | before using it. | |
565 | ||
566 | - Support for vendor specific EAP methods using Expanded EAP types. The | |
b6b90b68 | 567 | interface to EAP modules has been slightly changed, so make sure to |
fdc7c943 | 568 | check the changes if you're already rolling your own modules. |
83e0d841 | 569 | |
fb6d76cd | 570 | |
5076770c AS |
571 | strongswan-4.1.9 |
572 | ---------------- | |
573 | ||
800b3356 AS |
574 | - The default _updown script now dynamically inserts and removes ip6tables |
575 | firewall rules if leftfirewall=yes is set in IPv6 connections. New IPv6 | |
576 | net-net and roadwarrior (PSK/RSA) scenarios for both IKEv1 and IKEV2 were | |
577 | added. | |
5076770c | 578 | |
6f274c2a MW |
579 | - Implemented RFC4478 repeated authentication to force EAP/Virtual-IP clients |
580 | to reestablish an IKE_SA within a given timeframe. | |
581 | ||
582 | - strongSwan Manager supports configuration listing, initiation and termination | |
583 | of IKE and CHILD_SAs. | |
584 | ||
585 | - Fixes and improvements to multithreading code. | |
586 | ||
8b678ad4 | 587 | - IKEv2 plugins have been renamed to libcharon-* to avoid naming conflicts. |
b6b90b68 | 588 | Make sure to remove the old plugins in $libexecdir/ipsec, otherwise they get |
8b678ad4 | 589 | loaded twice. |
5076770c | 590 | |
83e0d841 | 591 | |
b82e8231 AS |
592 | strongswan-4.1.8 |
593 | ---------------- | |
594 | ||
5076770c | 595 | - Removed recursive pthread mutexes since uClibc doesn't support them. |
b82e8231 AS |
596 | |
597 | ||
a4a3632c AS |
598 | strongswan-4.1.7 |
599 | ---------------- | |
600 | ||
601 | - In NAT traversal situations and multiple queued Quick Modes, | |
602 | those pending connections inserted by auto=start after the | |
603 | port floating from 500 to 4500 were erronously deleted. | |
604 | ||
6e193274 | 605 | - Added a "forceencaps" connection parameter to enforce UDP encapsulation |
078b6008 | 606 | to surmount restrictive firewalls. NAT detection payloads are faked to |
6e193274 MW |
607 | simulate a NAT situation and trick the other peer into NAT mode (IKEv2 only). |
608 | ||
609 | - Preview of strongSwan Manager, a web based configuration and monitoring | |
610 | application. It uses a new XML control interface to query the IKEv2 daemon | |
611 | (see http://trac.strongswan.org/wiki/Manager). | |
612 | ||
613 | - Experimental SQLite configuration backend which will provide the configuration | |
614 | interface for strongSwan Manager in future releases. | |
615 | ||
616 | - Further improvements to MOBIKE support. | |
617 | ||
a4a3632c | 618 | |
3dcf9dbd AS |
619 | strongswan-4.1.6 |
620 | ---------------- | |
621 | ||
3eac4dfd AS |
622 | - Since some third party IKEv2 implementations run into |
623 | problems with strongSwan announcing MOBIKE capability per | |
624 | default, MOBIKE can be disabled on a per-connection-basis | |
625 | using the mobike=no option. Whereas mobike=no disables the | |
626 | sending of the MOBIKE_SUPPORTED notification and the floating | |
627 | to UDP port 4500 with the IKE_AUTH request even if no NAT | |
628 | situation has been detected, strongSwan will still support | |
629 | MOBIKE acting as a responder. | |
630 | ||
631 | - the default ipsec routing table plus its corresponding priority | |
632 | used for inserting source routes has been changed from 100 to 220. | |
633 | It can be configured using the --with-ipsec-routing-table and | |
b6b90b68 MW |
634 | --with-ipsec-routing-table-prio options. |
635 | ||
bdc0b55b AS |
636 | - the --enable-integrity-test configure option tests the |
637 | integrity of the libstrongswan crypto code during the charon | |
638 | startup. | |
b6b90b68 | 639 | |
3eac4dfd AS |
640 | - the --disable-xauth-vid configure option disables the sending |
641 | of the XAUTH vendor ID. This can be used as a workaround when | |
642 | interoperating with some Windows VPN clients that get into | |
643 | trouble upon reception of an XAUTH VID without eXtended | |
644 | AUTHentication having been configured. | |
b6b90b68 | 645 | |
f872f9d1 AS |
646 | - ipsec stroke now supports the rereadsecrets, rereadaacerts, |
647 | rereadacerts, and listacerts options. | |
3dcf9dbd AS |
648 | |
649 | ||
7ad634a2 AS |
650 | strongswan-4.1.5 |
651 | ---------------- | |
652 | ||
653 | - If a DNS lookup failure occurs when resolving right=%<FQDN> | |
654 | or right=<FQDN> combined with rightallowany=yes then the | |
655 | connection is not updated by ipsec starter thus preventing | |
656 | the disruption of an active IPsec connection. Only if the DNS | |
657 | lookup successfully returns with a changed IP address the | |
658 | corresponding connection definition is updated. | |
659 | ||
8f5b363c MW |
660 | - Routes installed by the keying daemons are now in a separate |
661 | routing table with the ID 100 to avoid conflicts with the main | |
662 | table. Route lookup for IKEv2 traffic is done in userspace to ignore | |
663 | routes installed for IPsec, as IKE traffic shouldn't get encapsulated. | |
664 | ||
7ad634a2 | 665 | |
e93c68ba AS |
666 | strongswan-4.1.4 |
667 | ---------------- | |
668 | ||
669 | - The pluto IKEv1 daemon now exhibits the same behaviour as its | |
670 | IKEv2 companion charon by inserting an explicit route via the | |
671 | _updown script only if a sourceip exists. This is admissible | |
672 | since routing through the IPsec tunnel is handled automatically | |
b7af55ac AS |
673 | by NETKEY's IPsec policies. As a consequence the left|rightnexthop |
674 | parameter is not required any more. | |
078ce348 AS |
675 | |
676 | - The new IKEv1 parameter right|leftallowany parameters helps to handle | |
677 | the case where both peers possess dynamic IP addresses that are | |
678 | usually resolved using DynDNS or a similar service. The configuration | |
679 | ||
680 | right=peer.foo.bar | |
681 | rightallowany=yes | |
682 | ||
683 | can be used by the initiator to start up a connection to a peer | |
684 | by resolving peer.foo.bar into the currently allocated IP address. | |
685 | Thanks to the rightallowany flag the connection behaves later on | |
686 | as | |
687 | ||
688 | right=%any | |
689 | ||
690 | so that the peer can rekey the connection as an initiator when his | |
1fbdab85 AS |
691 | IP address changes. An alternative notation is |
692 | ||
693 | right=%peer.foo.bar | |
694 | ||
695 | which will implicitly set rightallowany=yes. | |
696 | ||
697 | - ipsec starter now fails more gracefully in the presence of parsing | |
698 | errors. Flawed ca and conn section are discarded and pluto is started | |
699 | if non-fatal errors only were encountered. If right=%peer.foo.bar | |
700 | cannot be resolved by DNS then right=%any will be used so that passive | |
701 | connections as a responder are still possible. | |
078ce348 | 702 | |
a0a0bdd7 AS |
703 | - The new pkcs11initargs parameter that can be placed in the |
704 | setup config section of /etc/ipsec.conf allows the definition | |
705 | of an argument string that is used with the PKCS#11 C_Initialize() | |
706 | function. This non-standard feature is required by the NSS softoken | |
707 | library. This patch was contributed by Robert Varga. | |
b6b90b68 | 708 | |
a0a0bdd7 AS |
709 | - Fixed a bug in ipsec starter introduced by strongswan-2.8.5 |
710 | which caused a segmentation fault in the presence of unknown | |
711 | or misspelt keywords in ipsec.conf. This bug fix was contributed | |
712 | by Robert Varga. | |
713 | ||
e3606f2b MW |
714 | - Partial support for MOBIKE in IKEv2. The initiator acts on interface/ |
715 | address configuration changes and updates IKE and IPsec SAs dynamically. | |
e93c68ba | 716 | |
06651827 | 717 | |
a3354a69 AS |
718 | strongswan-4.1.3 |
719 | ---------------- | |
720 | ||
b6b90b68 | 721 | - IKEv2 peer configuration selection now can be based on a given |
35d4809c AS |
722 | certification authority using the rightca= statement. |
723 | ||
724 | - IKEv2 authentication based on RSA signatures now can handle multiple | |
41e16cf4 AS |
725 | certificates issued for a given peer ID. This allows a smooth transition |
726 | in the case of a peer certificate renewal. | |
a3354a69 | 727 | |
998ca0ea MW |
728 | - IKEv2: Support for requesting a specific virtual IP using leftsourceip on the |
729 | client and returning requested virtual IPs using rightsourceip=%config | |
730 | on the server. If the server does not support configuration payloads, the | |
731 | client enforces its leftsourceip parameter. | |
732 | ||
733 | - The ./configure options --with-uid/--with-gid allow pluto and charon | |
734 | to drop their privileges to a minimum and change to an other UID/GID. This | |
735 | improves the systems security, as a possible intruder may only get the | |
736 | CAP_NET_ADMIN capability. | |
737 | ||
b6b90b68 | 738 | - Further modularization of charon: Pluggable control interface and |
998ca0ea MW |
739 | configuration backend modules provide extensibility. The control interface |
740 | for stroke is included, and further interfaces using DBUS (NetworkManager) | |
741 | or XML are on the way. A backend for storing configurations in the daemon | |
b6b90b68 | 742 | is provided and more advanced backends (using e.g. a database) are trivial |
998ca0ea | 743 | to implement. |
a3354a69 | 744 | |
41e16cf4 AS |
745 | - Fixed a compilation failure in libfreeswan occuring with Linux kernel |
746 | headers > 2.6.17. | |
747 | ||
748 | ||
8ea7b96f AS |
749 | strongswan-4.1.2 |
750 | ---------------- | |
751 | ||
e23d98a7 | 752 | - Support for an additional Diffie-Hellman exchange when creating/rekeying |
37fb0355 MW |
753 | a CHILD_SA in IKEv2 (PFS). PFS is enabled when the proposal contains a |
754 | DH group (e.g. "esp=aes128-sha1-modp1536"). Further, DH group negotiation | |
755 | is implemented properly for rekeying. | |
756 | ||
757 | - Support for the AES-XCBC-96 MAC algorithm for IPsec SAs when using IKEv2 | |
758 | (requires linux >= 2.6.20). It is enabled using e.g. "esp=aes256-aesxcbc". | |
759 | ||
d931f465 MW |
760 | - Working IPv4-in-IPv6 and IPv6-in-IPv4 tunnels for linux >= 2.6.21. |
761 | ||
37fb0355 MW |
762 | - Added support for EAP modules which do not establish an MSK. |
763 | ||
dfbe2a0f | 764 | - Removed the dependencies from the /usr/include/linux/ headers by |
9f78f957 | 765 | including xfrm.h, ipsec.h, and pfkeyv2.h in the distribution. |
b6b90b68 | 766 | |
9f78f957 AS |
767 | - crlNumber is now listed by ipsec listcrls |
768 | ||
8ea7b96f AS |
769 | - The xauth_modules.verify_secret() function now passes the |
770 | connection name. | |

773 | strongswan-4.1.1 |
774 | ---------------- | |
775 | ||
776 | - Server side cookie support. If to may IKE_SAs are in CONNECTING state, | |
777 | cookies are enabled and protect against DoS attacks with faked source | |
778 | addresses. Number of IKE_SAs in CONNECTING state is also limited per | |
779 | peer address to avoid resource exhaustion. IKE_SA_INIT messages are | |
780 | compared to properly detect retransmissions and incoming retransmits are | |
781 | detected even if the IKE_SA is blocked (e.g. doing OCSP fetches). | |
782 | ||
db88e37d AS |
783 | - The IKEv2 daemon charon now supports dynamic http- and ldap-based CRL |
784 | fetching enabled by crlcheckinterval > 0 and caching fetched CRLs | |
785 | enabled by cachecrls=yes. | |
786 | ||
3b4f7d92 AS |
787 | - Added the configuration options --enable-nat-transport which enables |
788 | the potentially insecure NAT traversal for IPsec transport mode and | |
789 | --disable-vendor-id which disables the sending of the strongSwan | |
790 | vendor ID. | |
791 | ||
792 | - Fixed a long-standing bug in the pluto IKEv1 daemon which caused | |
793 | a segmentation fault if a malformed payload was detected in the | |
794 | IKE MR2 message and pluto tried to send an encrypted notification | |
795 | message. | |
796 | ||
46b9ff68 AS |
797 | - Added the NATT_IETF_02_N Vendor ID in order to support IKEv1 connections |
798 | with Windows 2003 Server which uses a wrong VID hash. | |
799 | ||
3b4f7d92 | 800 | |
34bbd0c3 | 801 | strongswan-4.1.0 |
cd3958f8 AS |
802 | ---------------- |
803 | ||
804 | - Support of SHA2_384 hash function for protecting IKEv1 | |
805 | negotiations and support of SHA2 signatures in X.509 certificates. | |
806 | ||
807 | - Fixed a serious bug in the computation of the SHA2-512 HMAC | |
808 | function. Introduced automatic self-test of all IKEv1 hash | |
809 | and hmac functions during pluto startup. Failure of a self-test | |
810 | currently issues a warning only but does not exit pluto [yet]. | |
811 | ||
9b45443d MW |
812 | - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2. |
813 | ||
c5d0fbb6 | 814 | - Full support of CA information sections. ipsec listcainfos |
b6b90b68 | 815 | now shows all collected crlDistributionPoints and OCSP |
c5d0fbb6 AS |
816 | accessLocations. |
817 | ||
69ed04bf AS |
818 | - Support of the Online Certificate Status Protocol (OCSP) for IKEv2. |
819 | This feature requires the HTTP fetching capabilities of the libcurl | |
820 | library which must be enabled by setting the --enable-http configure | |
821 | option. | |
822 | ||
9b45443d MW |
823 | - Refactored core of the IKEv2 message processing code, allowing better |
824 | code reuse and separation. | |
825 | ||
826 | - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration | |
827 | payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted | |
828 | by the requestor and installed in a resolv.conf file. | |
829 | ||
830 | - The IKEv2 daemon charon installs a route for each IPsec policy to use | |
831 | the correct source address even if an application does not explicitly | |
832 | specify it. | |
833 | ||
834 | - Integrated the EAP framework into charon which loads pluggable EAP library | |
835 | modules. The ipsec.conf parameter authby=eap initiates EAP authentication | |
836 | on the client side, while the "eap" parameter on the server side defines | |
837 | the EAP method to use for client authentication. | |
838 | A generic client side EAP-Identity module and an EAP-SIM authentication | |
839 | module using a third party card reader implementation are included. | |
840 | ||
841 | - Added client side support for cookies. | |
842 | ||
843 | - Integrated the fixes done at the IKEv2 interoperability bakeoff, including | |
844 | strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor | |
845 | fixes to enhance interoperability with other implementations. | |

848 | strongswan-4.0.7 |
849 | ---------------- | |
850 | ||
6fdf5f44 AS |
851 | - strongSwan now interoperates with the NCP Secure Entry Client, |
852 | the Shrew Soft VPN Client, and the Cisco VPN client, doing both | |
853 | XAUTH and Mode Config. | |
1c266d7d AS |
854 | |
855 | - UNITY attributes are now recognized and UNITY_BANNER is set | |
856 | to a default string. | |
857 | ||
858 | ||
2b4405a3 MW |
859 | strongswan-4.0.6 |
860 | ---------------- | |
861 | ||
e38a15d4 AS |
862 | - IKEv1: Support for extended authentication (XAUTH) in combination |
863 | with ISAKMP Main Mode RSA or PSK authentication. Both client and | |
864 | server side were implemented. Handling of user credentials can | |
865 | be done by a run-time loadable XAUTH module. By default user | |
b6b90b68 MW |
866 | credentials are stored in ipsec.secrets. |
867 | ||
2b4405a3 MW |
868 | - IKEv2: Support for reauthentication when rekeying |
869 | ||
5903179b | 870 | - IKEv2: Support for transport mode |
af87afed | 871 | |
5903179b | 872 | - fixed a lot of bugs related to byte order |
2b4405a3 | 873 | |
5903179b | 874 | - various other bugfixes |
2b4405a3 MW |
875 | |
876 | ||
0cd645d2 AS |
877 | strongswan-4.0.5 |
878 | ---------------- | |
879 | ||
880 | - IKEv1: Implementation of ModeConfig push mode via the new connection | |
881 | keyword modeconfig=push allows interoperability with Cisco VPN gateways. | |
882 | ||
883 | - IKEv1: The command ipsec statusall now shows "DPD active" for all | |
884 | ISAKMP SAs that are under active Dead Peer Detection control. | |
885 | ||
886 | - IKEv2: Charon's logging and debugging framework has been completely rewritten. | |
887 | Instead of logger, special printf() functions are used to directly | |
888 | print objects like hosts (%H) identifications (%D), certificates (%Q), | |
889 | etc. The number of debugging levels have been reduced to: | |
03bf883d | 890 | |
0cd645d2 | 891 | 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private) |
03bf883d | 892 | |
0cd645d2 AS |
893 | The debugging levels can either be specified statically in ipsec.conf as |
894 | ||
895 | config setup | |
03bf883d | 896 | charondebug="lib 1, cfg 3, net 2" |
0cd645d2 | 897 | |
03bf883d | 898 | or changed at runtime via stroke as |
0cd645d2 | 899 | |
03bf883d | 900 | ipsec stroke loglevel cfg 2 |
0cd645d2 AS |

902 | ||
48dc3934 MW |
903 | strongswan-4.0.4 |
904 | ---------------- | |
905 | ||
906 | - Implemented full support for IPv6-in-IPv6 tunnels. | |
907 | ||
908 | - Added configuration options for dead peer detection in IKEv2. dpd_action | |
909 | types "clear", "hold" and "restart" are supported. The dpd_timeout | |
910 | value is not used, as the normal retransmission policy applies to | |
911 | detect dead peers. The dpd_delay parameter enables sending of empty | |
912 | informational message to detect dead peers in case of inactivity. | |
913 | ||
914 | - Added support for preshared keys in IKEv2. PSK keys configured in | |
915 | ipsec.secrets are loaded. The authby parameter specifies the authentication | |
916 | method to authentificate ourself, the other peer may use PSK or RSA. | |
917 | ||
918 | - Changed retransmission policy to respect the keyingtries parameter. | |
919 | ||
112ad7c3 AS |
920 | - Added private key decryption. PEM keys encrypted with AES-128/192/256 |
921 | or 3DES are supported. | |
48dc3934 MW |
922 | |
923 | - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to | |
924 | encrypt IKE traffic. | |
925 | ||
926 | - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates | |
927 | signed with such a hash algorithm. | |
928 | ||
929 | - Added initial support for updown scripts. The actions up-host/client and | |
930 | down-host/client are executed. The leftfirewall=yes parameter | |
931 | uses the default updown script to insert dynamic firewall rules, a custom | |
932 | updown script may be specified with the leftupdown parameter. | |
933 | ||
934 | ||
a1310b6b MW |
935 | strongswan-4.0.3 |
936 | ---------------- | |
937 | ||
938 | - Added support for the auto=route ipsec.conf parameter and the | |
b6b90b68 MW |
939 | ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and |
940 | CHILD_SAs dynamically on demand when traffic is detected by the | |
a1310b6b MW |
941 | kernel. |
942 | ||
943 | - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter. | |
944 | As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only | |
945 | new keys are generated using perfect forward secrecy. An optional flag | |
946 | which enforces reauthentication will be implemented later. | |
947 | ||
b425d998 AS |
948 | - "sha" and "sha1" are now treated as synonyms in the ike= and esp= |
949 | algorithm configuration statements. | |
950 | ||
951 | ||
bf4df11f AS |
952 | strongswan-4.0.2 |
953 | ---------------- | |
954 | ||
623d3dcf AS |
955 | - Full X.509 certificate trust chain verification has been implemented. |
956 | End entity certificates can be exchanged via CERT payloads. The current | |
957 | default is leftsendcert=always, since CERTREQ payloads are not supported | |
958 | yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls. | |
efa40c11 | 959 | |
b6b90b68 | 960 | - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2 |
efa40c11 | 961 | would offer more possibilities for traffic selection, but the Linux kernel |
b6b90b68 | 962 | currently does not support it. That's why we stick with these simple |
efa40c11 MW |
963 | ipsec.conf rules for now. |
964 | ||
623d3dcf AS |
965 | - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no |
966 | IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear, | |
967 | dpddelay=60s). | |
968 | ||
efa40c11 MW |
969 | - Initial NAT traversal support in IKEv2. Charon includes NAT detection |
970 | notify payloads to detect NAT routers between the peers. It switches | |
971 | to port 4500, uses UDP encapsulated ESP packets, handles peer address | |
972 | changes gracefully and sends keep alive message periodically. | |
973 | ||
b6b90b68 MW |
974 | - Reimplemented IKE_SA state machine for charon, which allows simultaneous |
975 | rekeying, more shared code, cleaner design, proper retransmission | |
efa40c11 MW |
976 | and a more extensible code base. |
977 | ||
cfd8b27f AS |
978 | - The mixed PSK/RSA roadwarrior detection capability introduced by the |
979 | strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal | |
980 | payloads by the responder right before any defined IKE Main Mode state had | |
981 | been established. Although any form of bad proposal syntax was being correctly | |
982 | detected by the payload parser, the subsequent error handler didn't check | |
983 | the state pointer before logging current state information, causing an | |
984 | immediate crash of the pluto keying daemon due to a NULL pointer. | |
985 | ||
bf4df11f | 986 | |
7e81e975 MW |
987 | strongswan-4.0.1 |
988 | ---------------- | |
989 | ||
b6b90b68 | 990 | - Added algorithm selection to charon: New default algorithms for |
c15c3d4b MW |
991 | ike=aes128-sha-modp2048, as both daemons support it. The default |
992 | for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles | |
993 | the ike/esp parameter the same way as pluto. As this syntax does | |
b6b90b68 | 994 | not allow specification of a pseudo random function, the same |
c15c3d4b MW |
995 | algorithm as for integrity is used (currently sha/md5). Supported |
996 | algorithms for IKE: | |
997 | Encryption: aes128, aes192, aes256 | |
998 | Integrity/PRF: md5, sha (using hmac) | |
999 | DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192 | |
1000 | and for ESP: | |
b6b90b68 | 1001 | Encryption: aes128, aes192, aes256, 3des, blowfish128, |
c15c3d4b MW |
1002 | blowfish192, blowfish256 |
1003 | Integrity: md5, sha1 | |
1004 | More IKE encryption algorithms will come after porting libcrypto into | |
b6b90b68 | 1005 | libstrongswan. |
f2c2d395 | 1006 | |
c15c3d4b MW |
1007 | - initial support for rekeying CHILD_SAs using IKEv2. Currently no |
1008 | perfect forward secrecy is used. The rekeying parameters rekey, | |
22ff6f57 | 1009 | rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported |
c15c3d4b MW |
1010 | when using IKEv2. WARNING: charon currently is unable to handle |
1011 | simultaneous rekeying. To avoid such a situation, use a large | |
1012 | rekeyfuzz, or even better, set rekey=no on one peer. | |
22ff6f57 | 1013 | |
7e81e975 MW |
1014 | - support for host2host, net2net, host2net (roadwarrior) tunnels |
1015 | using predefined RSA certificates (see uml scenarios for | |
1016 | configuration examples). | |
1017 | ||
f2c2d395 MW |
1018 | - new build environment featuring autotools. Features such |
1019 | as HTTP, LDAP and smartcard support may be enabled using | |
b6b90b68 | 1020 | the ./configure script. Changing install directories |
f2c2d395 MW |
1021 | is possible, too. See ./configure --help for more details. |
1022 | ||
22ff6f57 MW |
1023 | - better integration of charon with ipsec starter, which allows |
1024 | (almost) transparent operation with both daemons. charon | |
1025 | handles ipsec commands up, down, status, statusall, listall, | |
1026 | listcerts and allows proper load, reload and delete of connections | |
1027 | via ipsec starter. | |
1028 | ||
b425d998 | 1029 | |
9820c0e2 MW |
1030 | strongswan-4.0.0 |
1031 | ---------------- | |
1032 | ||
1033 | - initial support of the IKEv2 protocol. Connections in | |
b6b90b68 | 1034 | ipsec.conf designated by keyexchange=ikev2 are negotiated |
9820c0e2 MW |
1035 | by the new IKEv2 charon keying daemon whereas those marked |
1036 | by keyexchange=ikev1 or the default keyexchange=ike are | |
1037 | handled thy the IKEv1 pluto keying daemon. Currently only | |
1038 | a limited subset of functions are available with IKEv2 | |
1039 | (Default AES encryption, authentication based on locally | |
1040 | imported X.509 certificates, unencrypted private RSA keys | |
1041 | in PKCS#1 file format, limited functionality of the ipsec | |
1042 | status command). | |
1043 | ||
1044 | ||
997358a6 MW |
1045 | strongswan-2.7.0 |
1046 | ---------------- | |
1047 | ||
1048 | - the dynamic iptables rules from the _updown_x509 template | |
1049 | for KLIPS and the _updown_policy template for NETKEY have | |
1050 | been merged into the default _updown script. The existing | |
1051 | left|rightfirewall keyword causes the automatic insertion | |
1052 | and deletion of ACCEPT rules for tunneled traffic upon | |
1053 | the successful setup and teardown of an IPsec SA, respectively. | |
1054 | left|rightfirwall can be used with KLIPS under any Linux 2.4 | |
1055 | kernel or with NETKEY under a Linux kernel version >= 2.6.16 | |
1056 | in conjuction with iptables >= 1.3.5. For NETKEY under a Linux | |
1057 | kernel version < 2.6.16 which does not support IPsec policy | |
1058 | matching yet, please continue to use a copy of the _updown_espmark | |
1059 | template loaded via the left|rightupdown keyword. | |
1060 | ||
1061 | - a new left|righthostaccess keyword has been introduced which | |
1062 | can be used in conjunction with left|rightfirewall and the | |
1063 | default _updown script. By default leftfirewall=yes inserts | |
1064 | a bi-directional iptables FORWARD rule for a local client network | |
1065 | with a netmask different from 255.255.255.255 (single host). | |
1066 | This does not allow to access the VPN gateway host via its | |
1067 | internal network interface which is part of the client subnet | |
1068 | because an iptables INPUT and OUTPUT rule would be required. | |
1069 | lefthostaccess=yes will cause this additional ACCEPT rules to | |
b6b90b68 | 1070 | be inserted. |
997358a6 MW |
1071 | |
1072 | - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal | |
1073 | payload is preparsed in order to find out whether the roadwarrior | |
1074 | requests PSK or RSA so that a matching connection candidate can | |
1075 | be found. | |
1076 | ||
1077 | ||
1078 | strongswan-2.6.4 | |
1079 | ---------------- | |
1080 | ||
1081 | - the new _updown_policy template allows ipsec policy based | |
1082 | iptables firewall rules. Required are iptables version | |
1083 | >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes | |
b6b90b68 | 1084 | the _updown_espmark template, so that no INPUT mangle rules |
997358a6 MW |
1085 | are required any more. |
1086 | ||
1087 | - added support of DPD restart mode | |
1088 | ||
1089 | - ipsec starter now allows the use of wildcards in include | |
1090 | statements as e.g. in "include /etc/my_ipsec/*.conf". | |
1091 | Patch courtesy of Matthias Haas. | |
1092 | ||
1093 | - the Netscape OID 'employeeNumber' is now recognized and can be | |
1094 | used as a Relative Distinguished Name in certificates. | |
1095 | ||
1096 | ||
1097 | strongswan-2.6.3 | |
1098 | ---------------- | |
1099 | ||
b6b90b68 | 1100 | - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec |
997358a6 MW |
1101 | command and not of ipsec setup any more. |
1102 | ||
1103 | - ipsec starter now supports AH authentication in conjunction with | |
1104 | ESP encryption. AH authentication is configured in ipsec.conf | |
1105 | via the auth=ah parameter. | |
b6b90b68 | 1106 | |
997358a6 MW |
1107 | - The command ipsec scencrypt|scdecrypt <args> is now an alias for |
1108 | ipsec whack --scencrypt|scdecrypt <args>. | |
1109 | ||
1110 | - get_sa_info() now determines for the native netkey IPsec stack | |
1111 | the exact time of the last use of an active eroute. This information | |
1112 | is used by the Dead Peer Detection algorithm and is also displayed by | |
1113 | the ipsec status command. | |
b6b90b68 | 1114 | |
997358a6 MW |
1115 | |
1116 | strongswan-2.6.2 | |
1117 | ---------------- | |
1118 | ||
1119 | - running under the native Linux 2.6 IPsec stack, the function | |
1120 | get_sa_info() is called by ipsec auto --status to display the current | |
1121 | number of transmitted bytes per IPsec SA. | |
1122 | ||
1123 | - get_sa_info() is also used by the Dead Peer Detection process to detect | |
1124 | recent ESP activity. If ESP traffic was received from the peer within | |
1125 | the last dpd_delay interval then no R_Y_THERE notification must be sent. | |
1126 | ||
1127 | - strongSwan now supports the Relative Distinguished Name "unstructuredName" | |
1128 | in ID_DER_ASN1_DN identities. The following notations are possible: | |
1129 | ||
1130 | rightid="unstructuredName=John Doe" | |
1131 | rightid="UN=John Doe" | |
1132 | ||
1133 | - fixed a long-standing bug which caused PSK-based roadwarrior connections | |
1134 | to segfault in the function id.c:same_id() called by keys.c:get_secret() | |
1135 | if an FQDN, USER_FQDN, or Key ID was defined, as in the following example. | |
1136 | ||
1137 | conn rw | |
1138 | right=%any | |
1139 | rightid=@foo.bar | |
1140 | authby=secret | |
1141 | ||
1142 | - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall). | |
1143 | ||
1144 | - ipsec starter didn't set host_addr and client.addr ports in whack msg. | |
1145 | ||
1146 | - in order to guarantee backwards-compatibility with the script-based | |
1147 | auto function (e.g. auto --replace), the ipsec starter scripts stores | |
1148 | the defaultroute information in the temporary file /var/run/ipsec.info. | |
1149 | ||
1150 | - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH | |
1151 | Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config | |
1152 | servers. | |
1153 | ||
1154 | - the ipsec starter now also recognizes the parameters authby=never and | |
1155 | type=passthrough|pass|drop|reject. | |
1156 | ||
1157 | ||
1158 | strongswan-2.6.1 | |
1159 | ---------------- | |
1160 | ||
1161 | - ipsec starter now supports the also parameter which allows | |
1162 | a modular structure of the connection definitions. Thus | |
1163 | "ipsec start" is now ready to replace "ipsec setup". | |
1164 | ||
1165 | ||
1166 | strongswan-2.6.0 | |
1167 | ---------------- | |
1168 | ||
1169 | - Mathieu Lafon's popular ipsec starter tool has been added to the | |
1170 | strongSwan distribution. Many thanks go to Stephan Scholz from astaro | |
1171 | for his integration work. ipsec starter is a C program which is going | |
1172 | to replace the various shell and awk starter scripts (setup, _plutoload, | |
1173 | _plutostart, _realsetup, _startklips, _confread, and auto). Since | |
1174 | ipsec.conf is now parsed only once, the starting of multiple tunnels is | |
1175 | accelerated tremedously. | |
1176 | ||
1177 | - Added support of %defaultroute to the ipsec starter. If the IP address | |
b6b90b68 | 1178 | changes, a HUP signal to the ipsec starter will automatically |
997358a6 MW |
1179 | reload pluto's connections. |
1180 | ||
1181 | - moved most compile time configurations from pluto/Makefile to | |
1182 | Makefile.inc by defining the options USE_LIBCURL, USE_LDAP, | |
1183 | USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE. | |
1184 | ||
1185 | - removed the ipsec verify and ipsec newhostkey commands | |
1186 | ||
1187 | - fixed some 64-bit issues in formatted print statements | |
1188 | ||
1189 | - The scepclient functionality implementing the Simple Certificate | |
1190 | Enrollment Protocol (SCEP) is nearly complete but hasn't been | |
1191 | documented yet. | |
1192 | ||
1193 | ||
1194 | strongswan-2.5.7 | |
1195 | ---------------- | |
1196 | ||
1197 | - CA certicates are now automatically loaded from a smartcard | |
1198 | or USB crypto token and appear in the ipsec auto --listcacerts | |
1199 | listing. | |
1200 | ||
1201 | ||
1202 | strongswan-2.5.6 | |
1203 | ---------------- | |
1204 | ||
1205 | - when using "ipsec whack --scencrypt <data>" with a PKCS#11 | |
1206 | library that does not support the C_Encrypt() Cryptoki | |
1207 | function (e.g. OpenSC), the RSA encryption is done in | |
1208 | software using the public key fetched from the smartcard. | |
1209 | ||
b6b90b68 | 1210 | - The scepclient function now allows to define the |
997358a6 MW |
1211 | validity of a self-signed certificate using the --days, |
1212 | --startdate, and --enddate options. The default validity | |
1213 | has been changed from one year to five years. | |
1214 | ||
1215 | ||
1216 | strongswan-2.5.5 | |
1217 | ---------------- | |
1218 | ||
1219 | - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11 | |
1220 | interface to other applications for RSA encryption and decryption | |
1221 | via the whack interface. Notation: | |
1222 | ||
1223 | ipsec whack --scencrypt <data> | |
1224 | [--inbase 16|hex|64|base64|256|text|ascii] | |
1225 | [--outbase 16|hex|64|base64|256|text|ascii] | |
1226 | [--keyid <keyid>] | |
1227 | ||
1228 | ipsec whack --scdecrypt <data> | |
1229 | [--inbase 16|hex|64|base64|256|text|ascii] | |
1230 | [--outbase 16|hex|64|base64|256|text|ascii] | |
1231 | [--keyid <keyid>] | |
1232 | ||
b6b90b68 | 1233 | The default setting for inbase and outbase is hex. |
997358a6 MW |
1234 | |
1235 | The new proxy interface can be used for securing symmetric | |
1236 | encryption keys required by the cryptoloop or dm-crypt | |
1237 | disk encryption schemes, especially in the case when | |
1238 | pkcs11keepstate=yes causes pluto to lock the pkcs11 slot | |
1239 | permanently. | |
1240 | ||
1241 | - if the file /etc/ipsec.secrets is lacking during the startup of | |
1242 | pluto then the root-readable file /etc/ipsec.d/private/myKey.der | |
1243 | containing a 2048 bit RSA private key and a matching self-signed | |
1244 | certificate stored in the file /etc/ipsec.d/certs/selfCert.der | |
1245 | is automatically generated by calling the function | |
1246 | ||
1247 | ipsec scepclient --out pkcs1 --out cert-self | |
1248 | ||
1249 | scepclient was written by Jan Hutter and Martin Willi, students | |
1250 | at the University of Applied Sciences in Rapperswil, Switzerland. | |
1251 | ||
1252 | ||
1253 | strongswan-2.5.4 | |
1254 | ---------------- | |
1255 | ||
1256 | - the current extension of the PKCS#7 framework introduced | |
1257 | a parsing error in PKCS#7 wrapped X.509 certificates that are | |
1258 | e.g. transmitted by Windows XP when multi-level CAs are used. | |
1259 | the parsing syntax has been fixed. | |
1260 | ||
1261 | - added a patch by Gerald Richter which tolerates multiple occurrences | |
1262 | of the ipsec0 interface when using KLIPS. | |
1263 | ||
1264 | ||
1265 | strongswan-2.5.3 | |
1266 | ---------------- | |
1267 | ||
1268 | - with gawk-3.1.4 the word "default2 has become a protected | |
1269 | keyword for use in switch statements and cannot be used any | |
1270 | more in the strongSwan scripts. This problem has been | |
1271 | solved by renaming "default" to "defaults" and "setdefault" | |
1272 | in the scripts _confread and auto, respectively. | |
1273 | ||
1274 | - introduced the parameter leftsendcert with the values | |
1275 | ||
1276 | always|yes (the default, always send a cert) | |
1277 | ifasked (send the cert only upon a cert request) | |
1278 | never|no (never send a cert, used for raw RSA keys and | |
b6b90b68 | 1279 | self-signed certs) |
997358a6 MW |
1280 | |
1281 | - fixed the initialization of the ESP key length to a default of | |
1282 | 128 bits in the case that the peer does not send a key length | |
1283 | attribute for AES encryption. | |
1284 | ||
1285 | - applied Herbert Xu's uniqueIDs patch | |
1286 | ||
1287 | - applied Herbert Xu's CLOEXEC patches | |
1288 | ||
1289 | ||
1290 | strongswan-2.5.2 | |
1291 | ---------------- | |
1292 | ||
1293 | - CRLs can now be cached also in the case when the issuer's | |
1294 | certificate does not contain a subjectKeyIdentifier field. | |
1295 | In that case the subjectKeyIdentifier is computed by pluto as the | |
1296 | 160 bit SHA-1 hash of the issuer's public key in compliance | |
1297 | with section 4.2.1.2 of RFC 3280. | |
1298 | ||
1299 | - Fixed a bug introduced by strongswan-2.5.1 which eliminated | |
1300 | not only multiple Quick Modes of a given connection but also | |
1301 | multiple connections between two security gateways. | |
1302 | ||
1303 | ||
1304 | strongswan-2.5.1 | |
1305 | ---------------- | |
1306 | ||
1307 | - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute | |
1308 | installed either by setting auto=route in ipsec.conf or by | |
1309 | a connection put into hold, generates an XFRM_AQUIRE event | |
1310 | for each packet that wants to use the not-yet exisiting | |
1311 | tunnel. Up to now each XFRM_AQUIRE event led to an entry in | |
1312 | the Quick Mode queue, causing multiple IPsec SA to be | |
1313 | established in rapid succession. Starting with strongswan-2.5.1 | |
1314 | only a single IPsec SA is established per host-pair connection. | |
1315 | ||
1316 | - Right after loading the PKCS#11 module, all smartcard slots are | |
1317 | searched for certificates. The result can be viewed using | |
1318 | the command | |
1319 | ||
1320 | ipsec auto --listcards | |
1321 | ||
1322 | The certificate objects found in the slots are numbered | |
1323 | starting with #1, #2, etc. This position number can be used to address | |
1324 | certificates (leftcert=%smartcard) and keys (: PIN %smartcard) | |
1325 | in ipsec.conf and ipsec.secrets, respectively: | |
1326 | ||
1327 | %smartcard (selects object #1) | |
1328 | %smartcard#1 (selects object #1) | |
1329 | %smartcard#3 (selects object #3) | |
1330 | ||
1331 | As an alternative the existing retrieval scheme can be used: | |
1332 | ||
1333 | %smartcard:45 (selects object with id=45) | |
1334 | %smartcard0 (selects first object in slot 0) | |
1335 | %smartcard4:45 (selects object in slot 4 with id=45) | |
1336 | ||
1337 | - Depending on the settings of CKA_SIGN and CKA_DECRYPT | |
1338 | private key flags either C_Sign() or C_Decrypt() is used | |
1339 | to generate a signature. | |
1340 | ||
1341 | - The output buffer length parameter siglen in C_Sign() | |
1342 | is now initialized to the actual size of the output | |
1343 | buffer prior to the function call. This fixes the | |
1344 | CKR_BUFFER_TOO_SMALL error that could occur when using | |
1345 | the OpenSC PKCS#11 module. | |
1346 | ||
1347 | - Changed the initialization of the PKCS#11 CK_MECHANISM in | |
1348 | C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }. | |
1349 | ||
1350 | - Refactored the RSA public/private key code and transferred it | |
1351 | from keys.c to the new pkcs1.c file as a preparatory step | |
1352 | towards the release of the SCEP client. | |
1353 | ||
1354 | ||
1355 | strongswan-2.5.0 | |
1356 | ---------------- | |
1357 | ||
1358 | - The loading of a PKCS#11 smartcard library module during | |
1359 | runtime does not require OpenSC library functions any more | |
1360 | because the corresponding code has been integrated into | |
1361 | smartcard.c. Also the RSAREF pkcs11 header files have been | |
1362 | included in a newly created pluto/rsaref directory so that | |
1363 | no external include path has to be defined any longer. | |
1364 | ||
1365 | - A long-awaited feature has been implemented at last: | |
1366 | The local caching of CRLs fetched via HTTP or LDAP, activated | |
1367 | by the parameter cachecrls=yes in the config setup section | |
1368 | of ipsec.conf. The dynamically fetched CRLs are stored under | |
1369 | a unique file name containing the issuer's subjectKeyID | |
1370 | in /etc/ipsec.d/crls. | |
b6b90b68 | 1371 | |
997358a6 MW |
1372 | - Applied a one-line patch courtesy of Michael Richardson |
1373 | from the Openswan project which fixes the kernel-oops | |
1374 | in KLIPS when an snmp daemon is running on the same box. | |
1375 | ||
1376 | ||
1377 | strongswan-2.4.4 | |
1378 | ---------------- | |
1379 | ||
1380 | - Eliminated null length CRL distribution point strings. | |
1381 | ||
1382 | - Fixed a trust path evaluation bug introduced with 2.4.3 | |
1383 | ||
1384 | ||
1385 | strongswan-2.4.3 | |
1386 | ---------------- | |
1387 | ||
1388 | - Improved the joint OCSP / CRL revocation policy. | |
1389 | OCSP responses have precedence over CRL entries. | |
1390 | ||
1391 | - Introduced support of CRLv2 reason codes. | |
1392 | ||
1393 | - Fixed a bug with key-pad equipped readers which caused | |
1394 | pluto to prompt for the pin via the console when the first | |
1395 | occasion to enter the pin via the key-pad was missed. | |
1396 | ||
1397 | - When pluto is built with LDAP_V3 enabled, the library | |
1398 | liblber required by newer versions of openldap is now | |
1399 | included. | |
1400 | ||
1401 | ||
1402 | strongswan-2.4.2 | |
1403 | ---------------- | |
1404 | ||
1405 | - Added the _updown_espmark template which requires all | |
1406 | incoming ESP traffic to be marked with a default mark | |
1407 | value of 50. | |
b6b90b68 | 1408 | |
997358a6 MW |
1409 | - Introduced the pkcs11keepstate parameter in the config setup |
1410 | section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11 | |
b6b90b68 | 1411 | session and login states are kept as long as possible during |
997358a6 MW |
1412 | the lifetime of pluto. This means that a PIN entry via a key |
1413 | pad has to be done only once. | |
1414 | ||
1415 | - Introduced the pkcs11module parameter in the config setup | |
1416 | section of ipsec.conf which specifies the PKCS#11 module | |
1417 | to be used with smart cards. Example: | |
b6b90b68 | 1418 | |
997358a6 | 1419 | pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo |
b6b90b68 | 1420 | |
997358a6 MW |
1421 | - Added support of smartcard readers equipped with a PIN pad. |
1422 | ||
1423 | - Added patch by Jay Pfeifer which detects when netkey | |
1424 | modules have been statically built into the Linux 2.6 kernel. | |
1425 | ||
1426 | - Added two patches by Herbert Xu. The first uses ip xfrm | |
1427 | instead of setkey to flush the IPsec policy database. The | |
1428 | second sets the optional flag in inbound IPComp SAs only. | |
b6b90b68 | 1429 | |
997358a6 MW |
1430 | - Applied Ulrich Weber's patch which fixes an interoperability |
1431 | problem between native IPsec and KLIPS systems caused by | |
1432 | setting the replay window to 32 instead of 0 for ipcomp. | |
1433 | ||
1434 | ||
1435 | strongswan-2.4.1 | |
1436 | ---------------- | |
1437 | ||
1438 | - Fixed a bug which caused an unwanted Mode Config request | |
1439 | to be initiated in the case where "right" was used to denote | |
1440 | the local side in ipsec.conf and "left" the remote side, | |
1441 | contrary to the recommendation that "right" be remote and | |
1442 | "left" be"local". | |
1443 | ||
1444 | ||
1445 | strongswan-2.4.0a | |
1446 | ----------------- | |
1447 | ||
1448 | - updated Vendor ID to strongSwan-2.4.0 | |
1449 | ||
1450 | - updated copyright statement to include David Buechi and | |
1451 | Michael Meier | |
b6b90b68 MW |
1452 | |
1453 | ||
997358a6 MW |
1454 | strongswan-2.4.0 |
1455 | ---------------- | |
1456 | ||
1457 | - strongSwan now communicates with attached smartcards and | |
1458 | USB crypto tokens via the standardized PKCS #11 interface. | |
1459 | By default the OpenSC library from www.opensc.org is used | |
1460 | but any other PKCS#11 library could be dynamically linked. | |
1461 | strongSwan's PKCS#11 API was implemented by David Buechi | |
1462 | and Michael Meier, both graduates of the Zurich University | |
1463 | of Applied Sciences in Winterthur, Switzerland. | |
1464 | ||
1465 | - When a %trap eroute is triggered by an outgoing IP packet | |
1466 | then the native IPsec stack of the Linux 2.6 kernel [often/ | |
1467 | always?] returns an XFRM_ACQUIRE message with an undefined | |
1468 | protocol family field and the connection setup fails. | |
1469 | As a workaround IPv4 (AF_INET) is now assumed. | |
b6b90b68 MW |
1470 | |
1471 | - the results of the UML test scenarios are now enhanced | |
997358a6 | 1472 | with block diagrams of the virtual network topology used |
b6b90b68 | 1473 | in a particular test. |
997358a6 MW |
1474 | |
1475 | ||
1476 | strongswan-2.3.2 | |
1477 | ---------------- | |
1478 | ||
1479 | - fixed IV used to decrypt informational messages. | |
1480 | This bug was introduced with Mode Config functionality. | |
b6b90b68 | 1481 | |
997358a6 MW |
1482 | - fixed NCP Vendor ID. |
1483 | ||
1484 | - undid one of Ulrich Weber's maximum udp size patches | |
1485 | because it caused a segmentation fault with NAT-ed | |
1486 | Delete SA messages. | |
b6b90b68 | 1487 | |
997358a6 MW |
1488 | - added UML scenarios wildcards and attr-cert which |
1489 | demonstrate the implementation of IPsec policies based | |
1490 | on wildcard parameters contained in Distinguished Names and | |
1491 | on X.509 attribute certificates, respectively. | |
1492 | ||
1493 | ||
1494 | strongswan-2.3.1 | |
1495 | ---------------- | |
1496 | ||
1497 | - Added basic Mode Config functionality | |
1498 | ||
1499 | - Added Mathieu Lafon's patch which upgrades the status of | |
1500 | the NAT-Traversal implementation to RFC 3947. | |
b6b90b68 | 1501 | |
997358a6 MW |
1502 | - The _startklips script now also loads the xfrm4_tunnel |
1503 | module. | |
b6b90b68 | 1504 | |
997358a6 MW |
1505 | - Added Ulrich Weber's netlink replay window size and |
1506 | maximum udp size patches. | |
1507 | ||
1508 | - UML testing now uses the Linux 2.6.10 UML kernel by default. | |
b6b90b68 | 1509 | |
997358a6 MW |
1510 | |
1511 | strongswan-2.3.0 | |
1512 | ---------------- | |
1513 | ||
1514 | - Eric Marchionni and Patrik Rayo, both recent graduates from | |
1515 | the Zuercher Hochschule Winterthur in Switzerland, created a | |
1516 | User-Mode-Linux test setup for strongSwan. For more details | |
1517 | please read the INSTALL and README documents in the testing | |
1518 | subdirectory. | |
1519 | ||
1520 | - Full support of group attributes based on X.509 attribute | |
b6b90b68 | 1521 | certificates. Attribute certificates can be generated |
997358a6 | 1522 | using the openac facility. For more details see |
b6b90b68 | 1523 | |
997358a6 | 1524 | man ipsec_openac. |
b6b90b68 | 1525 | |
997358a6 MW |
1526 | The group attributes can be used in connection definitions |
1527 | in order to give IPsec access to specific user groups. | |
1528 | This is done with the new parameter left|rightgroups as in | |
b6b90b68 | 1529 | |
997358a6 MW |
1530 | rightgroups="Research, Sales" |
1531 | ||
1532 | giving access to users possessing the group attributes | |
1533 | Research or Sales, only. | |
1534 | ||
1535 | - In Quick Mode clients with subnet mask /32 are now | |
b6b90b68 | 1536 | coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should |
997358a6 MW |
1537 | fix rekeying problems with the SafeNet/SoftRemote and NCP |
1538 | Secure Entry Clients. | |
1539 | ||
1540 | - Changed the defaults of the ikelifetime and keylife parameters | |
1541 | to 3h and 1h, respectively. The maximum allowable values are | |
1542 | now both set to 24 h. | |
1543 | ||
1544 | - Suppressed notification wars between two IPsec peers that | |
1545 | could e.g. be triggered by incorrect ISAKMP encryption. | |
1546 | ||
1547 | - Public RSA keys can now have identical IDs if either the | |
1548 | issuing CA or the serial number is different. The serial | |
1549 | number of a certificate is now shown by the command | |
b6b90b68 | 1550 | |
997358a6 MW |
1551 | ipsec auto --listpubkeys |
1552 | ||
1553 | ||
1554 | strongswan-2.2.2 | |
1555 | ---------------- | |
1556 | ||
1557 | - Added Tuomo Soini's sourceip feature which allows a strongSwan | |
1558 | roadwarrior to use a fixed Virtual IP (see README section 2.6) | |
1559 | and reduces the well-known four tunnel case on VPN gateways to | |
1560 | a single tunnel definition (see README section 2.4). | |
1561 | ||
1562 | - Fixed a bug occuring with NAT-Traversal enabled when the responder | |
1563 | suddenly turns initiator and the initiator cannot find a matching | |
1564 | connection because of the floated IKE port 4500. | |
b6b90b68 | 1565 | |
997358a6 MW |
1566 | - Removed misleading ipsec verify command from barf. |
1567 | ||
1568 | - Running under the native IP stack, ipsec --version now shows | |
1569 | the Linux kernel version (courtesy to the Openswan project). | |
1570 | ||
1571 | ||
1572 | strongswan-2.2.1 | |
1573 | ---------------- | |
1574 | ||
1575 | - Introduced the ipsec auto --listalgs monitoring command which lists | |
1576 | all currently registered IKE and ESP algorithms. | |
1577 | ||
1578 | - Fixed a bug in the ESP algorithm selection occuring when the strict flag | |
1579 | is set and the first proposed transform does not match. | |
b6b90b68 | 1580 | |
997358a6 MW |
1581 | - Fixed another deadlock in the use of the lock_certs_and_keys() mutex, |
1582 | occuring when a smartcard is present. | |
1583 | ||
1584 | - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event. | |
b6b90b68 | 1585 | |
997358a6 MW |
1586 | - Fixed the printing of the notification names (null) |
1587 | ||
1588 | - Applied another of Herbert Xu's Netlink patches. | |
1589 | ||
1590 | ||
1591 | strongswan-2.2.0 | |
1592 | ---------------- | |
1593 | ||
1594 | - Support of Dead Peer Detection. The connection parameter | |
1595 | ||
1596 | dpdaction=clear|hold | |
b6b90b68 | 1597 | |
997358a6 MW |
1598 | activates DPD for the given connection. |
1599 | ||
1600 | - The default Opportunistic Encryption (OE) policy groups are not | |
1601 | automatically included anymore. Those wishing to activate OE can include | |
1602 | the policy group with the following statement in ipsec.conf: | |
b6b90b68 | 1603 | |
997358a6 | 1604 | include /etc/ipsec.d/examples/oe.conf |
b6b90b68 | 1605 | |
997358a6 MW |
1606 | The default for [right|left]rsasigkey is now set to %cert. |
1607 | ||
1608 | - strongSwan now has a Vendor ID of its own which can be activated | |
1609 | using the compile option VENDORID | |
1610 | ||
1611 | - Applied Herbert Xu's patch which sets the compression algorithm correctly. | |
1612 | ||
1613 | - Applied Herbert Xu's patch fixing an ESPINUDP problem | |
1614 | ||
1615 | - Applied Herbert Xu's patch setting source/destination port numbers. | |
1616 | ||
1617 | - Reapplied one of Herbert Xu's NAT-Traversal patches which got | |
1618 | lost during the migration from SuperFreeS/WAN. | |

1626 | strongswan-2.1.5 | |
1627 | ---------------- | |
1628 | ||
1629 | - Thomas Walpuski made me aware of a potential DoS attack via | |
1630 | a PKCS#7-wrapped certificate bundle which could overwrite valid CA | |
1631 | certificates in Pluto's authority certificate store. This vulnerability | |
1632 | was fixed by establishing trust in CA candidate certificates up to a | |
1633 | trusted root CA prior to insertion into Pluto's chained list. | |
1634 | ||
1635 | - replaced the --assign option by the -v option in the auto awk script | |
1636 | in order to make it run with mawk under debian/woody. | |
1637 | ||
1638 | ||
1639 | strongswan-2.1.4 | |
1640 | ---------------- | |
1641 | ||
1642 | - Split of the status information between ipsec auto --status (concise) | |
1643 | and ipsec auto --statusall (verbose). Both commands can be used with | |
1644 | an optional connection selector: | |
1645 | ||
1646 | ipsec auto --status[all] <connection_name> | |
1647 | ||
1648 | - Added the description of X.509 related features to the ipsec_auto(8) | |
1649 | man page. | |
1650 | ||
1651 | - Hardened the ASN.1 parser in debug mode, especially the printing | |
1652 | of malformed distinguished names. | |
1653 | ||
1654 | - The size of an RSA public key received in a certificate is now restricted to | |
1655 | ||
1656 | 512 bits <= modulus length <= 8192 bits. | |
1657 | ||
1658 | - Fixed the debug mode enumeration. | |
1659 | ||
1660 | ||
1661 | strongswan-2.1.3 | |
1662 | ---------------- | |
1663 | ||
1664 | - Fixed another PKCS#7 vulnerability which could lead to an | |
1665 | endless loop while following the X.509 trust chain. | |
b6b90b68 | 1666 | |
997358a6 MW |
1667 | |
1668 | strongswan-2.1.2 | |
1669 | ---------------- | |
1670 | ||
1671 | - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski | |
1672 | that accepted end certificates having identical issuer and subject | |
1673 | distinguished names in a multi-tier X.509 trust chain. | |
b6b90b68 | 1674 | |
997358a6 MW |
1675 | |
1676 | strongswan-2.1.1 | |
1677 | ---------------- | |
1678 | ||
1679 | - Removed all remaining references to ipsec_netlink.h in KLIPS. | |
1680 | ||
1681 | ||
1682 | strongswan-2.1.0 | |
1683 | ---------------- | |
1684 | ||
1685 | - The new "ca" section allows to define the following parameters: | |
1686 | ||
1687 | ca kool | |
1688 | cacert=koolCA.pem # cacert of kool CA | |
1689 | ocspuri=http://ocsp.kool.net:8001 # ocsp server | |
1690 | ldapserver=ldap.kool.net # default ldap server | |
1691 | crluri=http://www.kool.net/kool.crl # crl distribution point | |
1692 | crluri2="ldap:///O=Kool, C= .." # crl distribution point #2 | |
1693 | auto=add # add, ignore | |
b6b90b68 | 1694 | |
997358a6 | 1695 | The ca definitions can be monitored via the command |
b6b90b68 | 1696 | |
997358a6 MW |
1697 | ipsec auto --listcainfos |
1698 | ||
1699 | - Fixed cosmetic corruption of /proc filesystem by integrating | |
1700 | D. Hugh Redelmeier's freeswan-2.06 kernel fixes. | |
1701 | ||
1702 | ||
1703 | strongswan-2.0.2 | |
1704 | ---------------- | |
1705 | ||
1706 | - Added support for the 818043 NAT-Traversal update of Microsoft's | |
1707 | Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode. | |
b6b90b68 MW |
1708 | |
1709 | - A symbolic link to libcrypto is now added in the kernel sources | |
997358a6 | 1710 | during kernel compilation |
b6b90b68 | 1711 | |
997358a6 MW |
1712 | - Fixed a couple of 64 bit issues (mostly casts to int). |
1713 | Thanks to Ken Bantoft who checked my sources on a 64 bit platform. | |
1714 | ||
1715 | - Replaced s[n]printf() statements in the kernel by ipsec_snprintf(). | |
1716 | Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro | |
1717 | of the FreeS/WAN team who solved this problem with the 2.4.25 kernel. | |
1718 | ||
1719 | ||
1720 | strongswan-2.0.1 | |
1721 | ---------------- | |
1722 | ||
1723 | - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName | |
1724 | certificate extension which contains no generalName item) can cause | |
1725 | a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has | |
1726 | been hardened to make it more robust against malformed ASN.1 objects. | |
1727 | ||
1728 | - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native | |
1729 | Linux 2.6 IPsec stack. | |
