1 | strongswan-4.3.6 |
2 | ---------------- | |
3 | ||
4 | - The IKEv1 and IKEV2 daemons now check certificate path length constraints. | |
5 | ||
44e41c4c AS |
6 | - More detailed IKEv2 EAP payload information in debug output |
7 | ||
2b2c69e9 | 8 | - IKEv2 EAP-SIM and EAP-AKA share joint libsimaka library |
44e41c4c | 9 | |
52fd0ef9 MW |
10 | - Added required userland changes for proper SHA256 and SHA384/512 in ESP that |
11 | will be introduced with Linux 2.6.33. The "sha256"/"sha2_256" keyword now | |
12 | configures the kernel with 128 bit truncation, not the non-standard 96 | |
13 | bit truncation used by previous releases. To use the old 96 bit truncation | |
14 | scheme, the new "sha256_96" proposal keyword has been introduced. | |
4c68a85a | 15 | |
2b2c69e9 MW |
16 | - Fixed IPComp in tunnel mode, stripping out the duplicated outer header. This |
17 | change makes IPcomp tunnel mode connections incompatible with previous | |
18 | releases; disable compression on such tunnels. | |
19 | ||
b6b90b68 MW |
20 | strongswan-4.3.5 |
21 | ---------------- | |
22 | ||
628f023d AS |
23 | - The IKEv1 pluto daemon can now use SQL-based address pools to deal out |
24 | virtual IP addresses as a Mode Config server. The pool capability has been | |
25 | migrated from charon's sql plugin to a new attr-sql plugin which is loaded | |
b42bfc79 | 26 | by libstrongswan and which can be used by both daemons either with a SQLite |
628f023d AS |
27 | or MySQL database and the corresponding plugin. |
28 | ||
b42bfc79 MW |
29 | - Plugin names have been streamlined: EAP plugins now have a dash after eap |
30 | (e.g. eap-sim), as it is used with the --enable-eap-sim ./configure option. | |
31 | Plugin configuration sections in strongswan.conf now use the same name as the | |
32 | plugin itself (i.e. with a dash). Make sure to update "load" directives and | |
33 | the affected plugin sections in existing strongswan.conf files. | |
34 | ||
d245f5cf AS |
35 | - The private/public key parsing and encoding has been split up into |
36 | separate pkcs1, pgp, pem and dnskey plugins. The public key implementation | |
37 | plugins gmp, gcrypt and openssl can all make use of them. | |
b6b90b68 | 38 | |
55b045ab MW |
39 | - The EAP-AKA plugin can use different backends for USIM/quintuplet |
40 | calculations, very similar to the EAP-SIM plugin. The existing 3GPP2 software | |
41 | implementation has been migrated to a separate plugin. | |
42 | ||
d245f5cf | 43 | - The IKEv2 daemon charon gained basic PGP support. It can use locally installed |
b6b90b68 MW |
44 | peer certificates and can issue signatures based on RSA private keys. |
45 | ||
46 | - The new 'ipsec pki' tool provides a set of commands to maintain a public | |
47 | key infrastructure. It currently supports operations to create RSA and ECDSA | |
48 | private/public keys, calculate fingerprints and issue or verify certificates. | |
49 | ||
50 | - Charon uses a monotonic time source for statistics and job queueing, behaving | |
51 | correctly if the system time changes (e.g. when using NTP). | |
52 | ||
53 | - In addition to time based rekeying, charon supports IPsec SA lifetimes based | |
54 | on processed volume or number of packets. They new ipsec.conf paramaters | |
55 | 'lifetime' (an alias to 'keylife'), 'lifebytes' and 'lifepackets' handle | |
56 | SA timeouts, while the parameters 'margintime' (an alias to rekeymargin), | |
57 | 'marginbytes' and 'marginpackets' trigger the rekeying before a SA expires. | |
58 | The existing parameter 'rekeyfuzz' affects all margins. | |
59 | ||
85af7a89 MW |
60 | - If no CA/Gateway certificate is specified in the NetworkManager plugin, |
61 | charon uses a set of trusted root certificates preinstalled by distributions. | |
62 | The directory containing CA certificates can be specified using the | |
63 | --with-nm-ca-dir=path configure option. | |
64 | ||
b80fa9ca | 65 | - Fixed the encoding of the Email relative distinguished name in left|rightid |
509f70c1 | 66 | statements. |
b80fa9ca | 67 | |
509f70c1 AS |
68 | - Fixed the broken parsing of PKCS#7 wrapped certificates by the pluto daemon. |
69 | ||
70 | - Fixed smartcard-based authentication in the pluto daemon which was broken by | |
71 | the ECDSA support introduced with the 4.3.2 release. | |
72 | ||
cea4bd8f AS |
73 | - A patch contributed by Heiko Hund fixes mixed IPv6 in IPv4 and vice versa |
74 | tunnels established with the IKEv1 pluto daemon. | |
75 | ||
509f70c1 AS |
76 | - The pluto daemon now uses the libstrongswan x509 plugin for certificates and |
77 | CRls and the struct id type was replaced by identification_t used by charon | |
78 | and the libstrongswan library. | |

430dd08a AS |
81 | strongswan-4.3.4 |
82 | ---------------- | |
83 | ||
84 | - IKEv2 charon daemon ported to FreeBSD and Mac OS X. Installation details can | |
85 | be found on wiki.strongswan.org. | |
86 | ||
87 | - ipsec statusall shows the number of bytes transmitted and received over | |
88 | ESP connections configured by the IKEv2 charon daemon. | |
89 | ||
90 | - The IKEv2 charon daemon supports include files in ipsec.secrets. | |
91 | ||
92 | ||
1c7f456a AS |
93 | strongswan-4.3.3 |
94 | ---------------- | |
95 | ||
aa74d705 AS |
96 | - The configuration option --enable-integrity-test plus the strongswan.conf |
97 | option libstrongswan.integrity_test = yes activate integrity tests | |
98 | of the IKE daemons charon and pluto, libstrongswan and all loaded | |
99 | plugins. Thus dynamic library misconfigurations and non-malicious file | |
100 | manipulations can be reliably detected. | |
101 | ||
1c7f456a AS |
102 | - The new default setting libstrongswan.ecp_x_coordinate_only=yes allows |
103 | IKEv1 interoperability with MS Windows using the ECP DH groups 19 and 20. | |
104 | ||
105 | - The IKEv1 pluto daemon now supports the AES-CCM and AES-GCM ESP | |
106 | authenticated encryption algorithms. | |
107 | ||
aa74d705 AS |
108 | - The IKEv1 pluto daemon now supports V4 OpenPGP keys. |
109 | ||
110 | - The RDN parser vulnerability discovered by Orange Labs research team | |
111 | was not completely fixed in version 4.3.2. Some more modifications | |
112 | had to be applied to the asn1_length() function to make it robust. | |
113 | ||
1c7f456a | 114 | |
80c0710c MW |
115 | strongswan-4.3.2 |
116 | ---------------- | |
117 | ||
118 | - The new gcrypt plugin provides symmetric cipher, hasher, RNG, Diffie-Hellman | |
119 | and RSA crypto primitives using the LGPL licensed GNU gcrypt library. | |
120 | ||
121 | - libstrongswan features an integrated crypto selftest framework for registered | |
122 | algorithms. The test-vector plugin provides a first set of test vectors and | |
123 | allows pluto and charon to rely on tested crypto algorithms. | |
124 | ||
b32af120 AS |
125 | - pluto can now use all libstrongswan plugins with the exception of x509 and xcbc. |
126 | Thanks to the openssl plugin, the ECP Diffie-Hellman groups 19, 20, 21, 25, and | |
127 | 26 as well as ECDSA-256, ECDSA-384, and ECDSA-521 authentication can be used | |
128 | with IKEv1. | |
126f2130 AS |
129 | |
130 | - Applying their fuzzing tool, the Orange Labs vulnerability research team found | |
131 | another two DoS vulnerabilities, one in the rather old ASN.1 parser of Relative | |
132 | Distinguished Names (RDNs) and a second one in the conversion of ASN.1 UTCTIME | |
133 | and GENERALIZEDTIME strings to a time_t value. | |
b6b90b68 | 134 | |

3bf7c249 MW |
136 | strongswan-4.3.1 |
137 | ---------------- | |
138 | ||
139 | - The nm plugin now passes DNS/NBNS server information to NetworkManager, | |
09dbca9f | 140 | allowing a gateway administrator to set DNS/NBNS configuration on clients |
3bf7c249 MW |
141 | dynamically. |
142 | ||
09dbca9f MW |
143 | - The nm plugin also accepts CA certificates for gateway authentication. If |
144 | a CA certificate is configured, strongSwan uses the entered gateway address | |
145 | as its idenitity, requiring the gateways certificate to contain the same as | |
146 | subjectAltName. This allows a gateway administrator to deploy the same | |
147 | certificates to Windows 7 and NetworkManager clients. | |
047b2e42 | 148 | |
050cc582 AS |
149 | - The command ipsec purgeike deletes IKEv2 SAs that don't have a CHILD SA. |
150 | The command ipsec down <conn>{n} deletes CHILD SA instance n of connection | |
151 | <conn> whereas ipsec down <conn>{*} deletes all CHILD SA instances. | |
152 | The command ipsec down <conn>[n] deletes IKE SA instance n of connection | |
153 | <conn> plus dependent CHILD SAs whereas ipsec down <conn>[*] deletes all | |
154 | IKE SA instances of connection <conn>. | |
155 | ||
09dbca9f | 156 | - Fixed a regression introduced in 4.3.0 where EAP authentication calculated |
047b2e42 MW |
157 | the AUTH payload incorrectly. Further, the EAP-MSCHAPv2 MSK key derivation |
158 | has been updated to be compatible with the Windows 7 Release Candidate. | |
159 | ||
160 | - Refactored installation of triggering policies. Routed policies are handled | |
161 | outside of IKE_SAs to keep them installed in any case. A tunnel gets | |
162 | established only once, even if initiation is delayed due network outages. | |
163 | ||
050cc582 AS |
164 | - Improved the handling of multiple acquire signals triggered by the kernel. |
165 | ||
166 | - Fixed two DoS vulnerabilities in the charon daemon that were discovered by | |
167 | fuzzing techniques: 1) Sending a malformed IKE_SA_INIT request leaved an | |
168 | incomplete state which caused a null pointer dereference if a subsequent | |
169 | CREATE_CHILD_SA request was sent. 2) Sending an IKE_AUTH request with either | |
170 | a missing TSi or TSr payload caused a null pointer derefence because the | |
b6b90b68 | 171 | checks for TSi and TSr were interchanged. The IKEv2 fuzzer used was |
050cc582 AS |
172 | developped by the Orange Labs vulnerability research team. The tool was |
173 | initially written by Gabriel Campana and is now maintained by Laurent Butti. | |
174 | ||
047b2e42 MW |
175 | - Added support for AES counter mode in ESP in IKEv2 using the proposal |
176 | keywords aes128ctr, aes192ctr and aes256ctr. | |
177 | ||
d44fd821 | 178 | - Further progress in refactoring pluto: Use of the curl and ldap plugins |
050cc582 AS |
179 | for fetching crls and OCSP. Use of the random plugin to get keying material |
180 | from /dev/random or /dev/urandom. Use of the openssl plugin as an alternative | |
d44fd821 | 181 | to the aes, des, sha1, sha2, and md5 plugins. The blowfish, twofish, and |
050cc582 | 182 | serpent encryption plugins are now optional and are not enabled by default. |
d44fd821 AS |

185 | strongswan-4.3.0 |
186 | ---------------- | |
187 | ||
81fc8e5f MW |
188 | - Support for the IKEv2 Multiple Authentication Exchanges extension (RFC4739). |
189 | Initiators and responders can use several authentication rounds (e.g. RSA | |
190 | followed by EAP) to authenticate. The new ipsec.conf leftauth/rightauth and | |
191 | leftauth2/rightauth2 parameters define own authentication rounds or setup | |
192 | constraints for the remote peer. See the ipsec.conf man page for more detials. | |
193 | ||
194 | - If glibc printf hooks (register_printf_function) are not available, | |
195 | strongSwan can use the vstr string library to run on non-glibc systems. | |
196 | ||
558c89e7 AS |
197 | - The IKEv2 charon daemon can now configure the ESP CAMELLIA-CBC cipher |
198 | (esp=camellia128|192|256). | |
247e665a | 199 | |
558c89e7 AS |
200 | - Refactored the pluto and scepclient code to use basic functions (memory |
201 | allocation, leak detective, chunk handling, printf_hooks, strongswan.conf | |
202 | attributes, ASN.1 parser, etc.) from the libstrongswan library. | |
b752f873 | 203 | |
558c89e7 AS |
204 | - Up to two DNS and WINS servers to be sent via IKEv1 ModeConfig can be |
205 | configured in the pluto section of strongswan.conf. | |

623bca40 AS |
208 | strongswan-4.2.14 |
209 | ----------------- | |
210 | ||
22180558 AS |
211 | - The new server-side EAP RADIUS plugin (--enable-eap-radius) |
212 | relays EAP messages to and from a RADIUS server. Succesfully | |
213 | tested with with a freeradius server using EAP-MD5 and EAP-SIM. | |
214 | ||
79b27294 AS |
215 | - A vulnerability in the Dead Peer Detection (RFC 3706) code was found by |
216 | Gerd v. Egidy <gerd.von.egidy@intra2net.com> of Intra2net AG affecting | |
217 | all Openswan and strongSwan releases. A malicious (or expired ISAKMP) | |
218 | R_U_THERE or R_U_THERE_ACK Dead Peer Detection packet can cause the | |
219 | pluto IKE daemon to crash and restart. No authentication or encryption | |
220 | is required to trigger this bug. One spoofed UDP packet can cause the | |
221 | pluto IKE daemon to restart and be unresponsive for a few seconds while | |
222 | restarting. This DPD null state vulnerability has been officially | |
223 | registered as CVE-2009-0790 and is fixed by this release. | |
224 | ||
22180558 AS |
225 | - ASN.1 to time_t conversion caused a time wrap-around for |
226 | dates after Jan 18 03:14:07 UTC 2038 on 32-bit platforms. | |
227 | As a workaround such dates are set to the maximum representable | |
228 | time, i.e. Jan 19 03:14:07 UTC 2038. | |
229 | ||
230 | - Distinguished Names containing wildcards (*) are not sent in the | |
b6b90b68 | 231 | IDr payload anymore. |
623bca40 AS |
232 | |
233 | ||
076e7853 AS |
234 | strongswan-4.2.13 |
235 | ----------------- | |
236 | ||
237 | - Fixed a use-after-free bug in the DPD timeout section of the | |
238 | IKEv1 pluto daemon which sporadically caused a segfault. | |
239 | ||
240 | - Fixed a crash in the IKEv2 charon daemon occuring with | |
b6b90b68 | 241 | mixed RAM-based and SQL-based virtual IP address pools. |
076e7853 | 242 | |
f15483ef AS |
243 | - Fixed ASN.1 parsing of algorithmIdentifier objects where the |
244 | parameters field is optional. | |
245 | ||
03991bc1 MW |
246 | - Ported nm plugin to NetworkManager 7.1. |
247 | ||
076e7853 | 248 | |
bfde75ee | 249 | strongswan-4.2.12 |
076e7853 | 250 | ----------------- |
bfde75ee AS |
251 | |
252 | - Support of the EAP-MSCHAPv2 protocol enabled by the option | |
253 | --enable-eap-mschapv2. Requires the MD4 hash algorithm enabled | |
254 | either by --enable-md4 or --enable-openssl. | |
255 | ||
256 | - Assignment of up to two DNS and up to two WINS servers to peers via | |
b6b90b68 | 257 | the IKEv2 Configuration Payload (CP). The IPv4 or IPv6 nameserver |
bfde75ee AS |
258 | addresses are defined in strongswan.conf. |
259 | ||
260 | - The strongSwan applet for the Gnome NetworkManager is now built and | |
261 | distributed as a separate tarball under the name NetworkManager-strongswan. | |
262 | ||
b6b90b68 | 263 | |
0519ca90 AS |
264 | strongswan-4.2.11 |
265 | ----------------- | |
266 | ||
ae1ae574 AS |
267 | - Fixed ESP NULL encryption broken by the refactoring of keymat.c. |
268 | Also introduced proper initialization and disposal of keying material. | |
269 | ||
270 | - Fixed the missing listing of connection definitions in ipsec statusall | |
271 | broken by an unfortunate local variable overload. | |
0519ca90 AS |
272 | |
273 | ||
4856241c MW |
274 | strongswan-4.2.10 |
275 | ----------------- | |
276 | ||
277 | - Several performance improvements to handle thousands of tunnels with almost | |
278 | linear upscaling. All relevant data structures have been replaced by faster | |
279 | counterparts with better lookup times. | |
280 | ||
281 | - Better parallelization to run charon on multiple cores. Due to improved | |
282 | ressource locking and other optimizations the daemon can take full | |
283 | advantage of 16 or even more cores. | |
284 | ||
285 | - The load-tester plugin can use a NULL Diffie-Hellman group and simulate | |
286 | unique identities and certificates by signing peer certificates using a CA | |
287 | on the fly. | |
288 | ||
289 | - The redesigned stroke in-memory IP pool handles leases. The "ipsec leases" | |
290 | command queries assigned leases. | |
291 | ||
292 | - Added support for smartcards in charon by using the ENGINE API provided by | |
293 | OpenSSL, based on patches by Michael Roßberg. | |
294 | ||
295 | - The Padlock plugin supports the hardware RNG found on VIA CPUs to provide a | |
296 | reliable source of randomness. | |
297 | ||
73937bd8 MW |
298 | strongswan-4.2.9 |
299 | ---------------- | |
300 | ||
509e07c5 AS |
301 | - Flexible configuration of logging subsystem allowing to log to multiple |
302 | syslog facilities or to files using fine-grained log levels for each target. | |
73937bd8 MW |
303 | |
304 | - Load testing plugin to do stress testing of the IKEv2 daemon against self | |
305 | or another host. Found and fixed issues during tests in the multi-threaded | |
306 | use of the OpenSSL plugin. | |
307 | ||
308 | - Added profiling code to synchronization primitives to find bottlenecks if | |
7bdc931e | 309 | running on multiple cores. Found and fixed an issue where parts of the |
73937bd8 MW |
310 | Diffie-Hellman calculation acquired an exclusive lock. This greatly improves |
311 | parallelization to multiple cores. | |
312 | ||
509e07c5 AS |
313 | - updown script invocation has been separated into a plugin of its own to |
314 | further slim down the daemon core. | |
73937bd8 | 315 | |
509e07c5 | 316 | - Separated IKE_SA/CHILD_SA key derivation process into a closed system, |
7bdc931e | 317 | allowing future implementations to use a secured environment in e.g. kernel |
73937bd8 MW |
318 | memory or hardware. |
319 | ||
509e07c5 AS |
320 | - The kernel interface of charon has been modularized. XFRM NETLINK (default) |
321 | and PFKEY (--enable-kernel-pfkey) interface plugins for the native IPsec | |
322 | stack of the Linux 2.6 kernel as well as a PFKEY interface for the KLIPS | |
323 | IPsec stack (--enable-kernel-klips) are provided. | |
324 | ||
325 | - Basic Mobile IPv6 support has been introduced, securing Binding Update | |
326 | messages as well as tunneled traffic between Mobile Node and Home Agent. | |
327 | The installpolicy=no option allows peaceful cooperation with a dominant | |
328 | mip6d daemon and the new type=transport_proxy implements the special MIPv6 | |
329 | IPsec transport proxy mode where the IKEv2 daemon uses the Care-of-Address | |
330 | but the IPsec SA is set up for the Home Adress. | |
7bdc931e | 331 | |
4dc0dce8 AS |
332 | - Implemented migration of Mobile IPv6 connections using the KMADDRESS |
333 | field contained in XFRM_MSG_MIGRATE messages sent by the mip6d daemon | |
334 | via the Linux 2.6.28 (or appropriately patched) kernel. | |
335 | ||

e39b271b AS |
337 | strongswan-4.2.8 |
338 | ---------------- | |
339 | ||
5dadb16e | 340 | - IKEv2 charon daemon supports authentication based on raw public keys |
e39b271b AS |
341 | stored in the SQL database backend. The ipsec listpubkeys command |
342 | lists the available raw public keys via the stroke interface. | |
343 | ||
4f0241e6 MW |
344 | - Several MOBIKE improvements: Detect changes in NAT mappings in DPD exchanges, |
345 | handle events if kernel detects NAT mapping changes in UDP-encapsulated | |
346 | ESP packets (requires kernel patch), reuse old addesses in MOBIKE updates as | |
347 | long as possible and other fixes. | |
348 | ||
5dadb16e AS |
349 | - Fixed a bug in addr_in_subnet() which caused insertion of wrong source |
350 | routes for destination subnets having netwmasks not being a multiple of 8 bits. | |
351 | Thanks go to Wolfgang Steudel, TU Ilmenau for reporting this bug. | |
352 | ||
e39b271b | 353 | |
e376d75f MW |
354 | strongswan-4.2.7 |
355 | ---------------- | |
356 | ||
b37cda82 AS |
357 | - Fixed a Denial-of-Service vulnerability where an IKE_SA_INIT message with |
358 | a KE payload containing zeroes only can cause a crash of the IKEv2 charon | |
359 | daemon due to a NULL pointer returned by the mpz_export() function of the | |
360 | GNU Multiprecision Library (GMP). Thanks go to Mu Dynamics Research Labs | |
b6b90b68 | 361 | for making us aware of this problem. |
b37cda82 | 362 | |
b6b90b68 | 363 | - The new agent plugin provides a private key implementation on top of an |
e376d75f MW |
364 | ssh-agent. |
365 | ||
366 | - The NetworkManager plugin has been extended to support certificate client | |
b1f47854 | 367 | authentication using RSA keys loaded from a file or using ssh-agent. |
e376d75f MW |
368 | |
369 | - Daemon capability dropping has been ported to libcap and must be enabled | |
370 | explicitly --with-capabilities=libcap. Future version will support the | |
371 | newer libcap2 library. | |
372 | ||
b37cda82 AS |
373 | - ipsec listalgs lists the IKEv2 cryptografic algorithms registered with the |
374 | charon keying daemon. | |
375 | ||
376 | ||
9f9d6ece AS |
377 | strongswan-4.2.6 |
378 | ---------------- | |
379 | ||
609166f4 MW |
380 | - A NetworkManager plugin allows GUI-based configuration of road-warrior |
381 | clients in a simple way. It features X509 based gateway authentication | |
382 | and EAP client authentication, tunnel setup/teardown and storing passwords | |
383 | in the Gnome Keyring. | |
384 | ||
385 | - A new EAP-GTC plugin implements draft-sheffer-ikev2-gtc-00.txt and allows | |
386 | username/password authentication against any PAM service on the gateway. | |
b6b90b68 | 387 | The new EAP method interacts nicely with the NetworkManager plugin and allows |
609166f4 MW |
388 | client authentication against e.g. LDAP. |
389 | ||
390 | - Improved support for the EAP-Identity method. The new ipsec.conf eap_identity | |
391 | parameter defines an additional identity to pass to the server in EAP | |
392 | authentication. | |
393 | ||
9f9d6ece AS |
394 | - The "ipsec statusall" command now lists CA restrictions, EAP |
395 | authentication types and EAP identities. | |
396 | ||
397 | - Fixed two multithreading deadlocks occurring when starting up | |
398 | several hundred tunnels concurrently. | |
399 | ||
400 | - Fixed the --enable-integrity-test configure option which | |
401 | computes a SHA-1 checksum over the libstrongswan library. | |
402 | ||
403 | ||
174216c7 AS |
404 | strongswan-4.2.5 |
405 | ---------------- | |
406 | ||
b6b90b68 | 407 | - Consistent logging of IKE and CHILD SAs at the audit (AUD) level. |
8124e491 AS |
408 | |
409 | - Improved the performance of the SQL-based virtual IP address pool | |
410 | by introducing an additional addresses table. The leases table | |
411 | storing only history information has become optional and can be | |
412 | disabled by setting charon.plugins.sql.lease_history = no in | |
413 | strongswan.conf. | |
414 | ||
eb0cc338 | 415 | - The XFRM_STATE_AF_UNSPEC flag added to xfrm.h allows IPv4-over-IPv6 |
de5f70e7 | 416 | and IPv6-over-IPv4 tunnels with the 2.6.26 and later Linux kernels. |
eb0cc338 | 417 | |
174216c7 AS |
418 | - management of different virtual IP pools for different |
419 | network interfaces have become possible. | |
420 | ||
b6b90b68 | 421 | - fixed a bug which prevented the assignment of more than 256 |
174216c7 AS |
422 | virtual IP addresses from a pool managed by an sql database. |
423 | ||
8124e491 AS |
424 | - fixed a bug which did not delete own IPCOMP SAs in the kernel. |
425 | ||
b6b90b68 | 426 | |
179dd12c AS |
427 | strongswan-4.2.4 |
428 | ---------------- | |
429 | ||
9de95037 AS |
430 | - Added statistics functions to ipsec pool --status and ipsec pool --leases |
431 | and input validation checks to various ipsec pool commands. | |
179dd12c | 432 | |
73a8eed3 | 433 | - ipsec statusall now lists all loaded charon plugins and displays |
9de95037 | 434 | the negotiated IKEv2 cipher suite proposals. |
73a8eed3 AS |
435 | |
436 | - The openssl plugin supports the elliptic curve Diffie-Hellman groups | |
437 | 19, 20, 21, 25, and 26. | |
438 | ||
439 | - The openssl plugin supports ECDSA authentication using elliptic curve | |
440 | X.509 certificates. | |
441 | ||
442 | - Fixed a bug in stroke which caused multiple charon threads to close | |
443 | the file descriptors during packet transfers over the stroke socket. | |
b6b90b68 | 444 | |
e0bb4dbb AS |
445 | - ESP sequence numbers are now migrated in IPsec SA updates handled by |
446 | MOBIKE. Works only with Linux kernels >= 2.6.17. | |
447 | ||
179dd12c | 448 | |
83d9e870 AS |
449 | strongswan-4.2.3 |
450 | ---------------- | |
451 | ||
b6b90b68 | 452 | - Fixed the strongswan.conf path configuration problem that occurred when |
83d9e870 AS |
453 | --sysconfig was not set explicitly in ./configure. |
454 | ||
455 | - Fixed a number of minor bugs that where discovered during the 4th | |
456 | IKEv2 interoperability workshop in San Antonio, TX. | |
457 | ||
458 | ||
7f491111 MW |
459 | strongswan-4.2.2 |
460 | ---------------- | |
461 | ||
a57cd446 AS |
462 | - Plugins for libstrongswan and charon can optionally be loaded according |
463 | to a configuration in strongswan.conf. Most components provide a | |
7f491111 | 464 | "load = " option followed by a space separated list of plugins to load. |
a57cd446 AS |
465 | This allows e.g. the fallback from a hardware crypto accelerator to |
466 | to software-based crypto plugins. | |
7f491111 MW |
467 | |
468 | - Charons SQL plugin has been extended by a virtual IP address pool. | |
a57cd446 AS |
469 | Configurations with a rightsourceip=%poolname setting query a SQLite or |
470 | MySQL database for leases. The "ipsec pool" command helps in administrating | |
471 | the pool database. See ipsec pool --help for the available options | |
472 | ||
473 | - The Authenticated Encryption Algorithms AES-CCM-8/12/16 and AES-GCM-8/12/16 | |
b6b90b68 | 474 | for ESP are now supported starting with the Linux 2.6.25 kernel. The |
a57cd446 AS |
475 | syntax is e.g. esp=aes128ccm12 or esp=aes256gcm16. |
476 | ||
7f491111 | 477 | |
5c5d67d6 AS |
478 | strongswan-4.2.1 |
479 | ---------------- | |
480 | ||
c306dfb1 | 481 | - Support for "Hash and URL" encoded certificate payloads has been implemented |
b1f8fc0c TB |
482 | in the IKEv2 daemon charon. Using the "certuribase" option of a CA section |
483 | allows to assign a base URL to all certificates issued by the specified CA. | |
484 | The final URL is then built by concatenating that base and the hex encoded | |
485 | SHA1 hash of the DER encoded certificate. Note that this feature is disabled | |
486 | by default and must be enabled using the option "charon.hash_and_url". | |
5c5d67d6 | 487 | |
58caabf7 MW |
488 | - The IKEv2 daemon charon now supports the "uniqueids" option to close multiple |
489 | IKE_SAs with the same peer. The option value "keep" prefers existing | |
490 | connection setups over new ones, where the value "replace" replaces existing | |
491 | connections. | |
b6b90b68 MW |
492 | |
493 | - The crypto factory in libstrongswan additionaly supports random number | |
58caabf7 | 494 | generators, plugins may provide other sources of randomness. The default |
c306dfb1 | 495 | plugin reads raw random data from /dev/(u)random. |
58caabf7 | 496 | |
b6b90b68 | 497 | - Extended the credential framework by a caching option to allow plugins |
58caabf7 | 498 | persistent caching of fetched credentials. The "cachecrl" option has been |
c306dfb1 | 499 | re-implemented. |
58caabf7 MW |
500 | |
501 | - The new trustchain verification introduced in 4.2.0 has been parallelized. | |
502 | Threads fetching CRL or OCSP information no longer block other threads. | |
5c5d67d6 | 503 | |
58caabf7 MW |
504 | - A new IKEv2 configuration attribute framework has been introduced allowing |
505 | plugins to provide virtual IP addresses, and in the future, other | |
506 | configuration attribute services (e.g. DNS/WINS servers). | |
5c5d67d6 | 507 | |
466abb49 | 508 | - The stroke plugin has been extended to provide virtual IP addresses from |
58caabf7 MW |
509 | a pool defined in ipsec.conf. The "rightsourceip" parameter now accepts |
510 | address pools in CIDR notation (e.g. 10.1.1.0/24). The parameter also accepts | |
511 | the value "%poolname", where "poolname" identifies a pool provided by a | |
466abb49 | 512 | separate plugin. |
58caabf7 | 513 | |
c306dfb1 | 514 | - Fixed compilation on uClibc and a couple of other minor bugs. |
58caabf7 | 515 | |
c306dfb1 | 516 | - Set DPD defaults in ipsec starter to dpd_delay=30s and dpd_timeout=150s. |
466abb49 AS |
517 | |
518 | - The IKEv1 pluto daemon now supports the ESP encryption algorithm CAMELLIA | |
c306dfb1 | 519 | with key lengths of 128, 192, and 256 bits, as well as the authentication |
466abb49 AS |
520 | algorithm AES_XCBC_MAC. Configuration example: esp=camellia192-aesxcbc. |
521 | ||
5c5d67d6 | 522 | |
a11ea97d AS |
523 | strongswan-4.2.0 |
524 | ---------------- | |
525 | ||
16f5dacd MW |
526 | - libstrongswan has been modularized to attach crypto algorithms, |
527 | credential implementations (keys, certificates) and fetchers dynamically | |
528 | through plugins. Existing code has been ported to plugins: | |
529 | - RSA/Diffie-Hellman implementation using the GNU Multi Precision library | |
530 | - X509 certificate system supporting CRLs, OCSP and attribute certificates | |
531 | - Multiple plugins providing crypto algorithms in software | |
532 | - CURL and OpenLDAP fetcher | |
a11ea97d | 533 | |
16f5dacd MW |
534 | - libstrongswan gained a relational database API which uses pluggable database |
535 | providers. Plugins for MySQL and SQLite are available. | |
536 | ||
537 | - The IKEv2 keying daemon charon is more extensible. Generic plugins may provide | |
538 | connection configuration, credentials and EAP methods or control the daemon. | |
539 | Existing code has been ported to plugins: | |
540 | - EAP-AKA, EAP-SIM, EAP-MD5 and EAP-Identity | |
541 | - stroke configuration, credential and control (compatible to pluto) | |
542 | - XML bases management protocol to control and query the daemon | |
543 | The following new plugins are available: | |
544 | - An experimental SQL configuration, credential and logging plugin on | |
545 | top of either MySQL or SQLite | |
546 | - A unit testing plugin to run tests at daemon startup | |
547 | ||
548 | - The authentication and credential framework in charon has been heavily | |
549 | refactored to support modular credential providers, proper | |
550 | CERTREQ/CERT payload exchanges and extensible authorization rules. | |
551 | ||
b6b90b68 | 552 | - The framework of strongSwan Manager has envolved to the web application |
16f5dacd MW |
553 | framework libfast (FastCGI Application Server w/ Templates) and is usable |
554 | by other applications. | |
b6b90b68 | 555 | |

557 | strongswan-4.1.11 |
558 | ----------------- | |
fb6d76cd | 559 | |
a561f74d AS |
560 | - IKE rekeying in NAT situations did not inherit the NAT conditions |
561 | to the rekeyed IKE_SA so that the UDP encapsulation was lost with | |
562 | the next CHILD_SA rekeying. | |
563 | ||
564 | - Wrong type definition of the next_payload variable in id_payload.c | |
b6b90b68 | 565 | caused an INVALID_SYNTAX error on PowerPC platforms. |
fb6d76cd | 566 | |
e6b50b3f AS |
567 | - Implemented IKEv2 EAP-SIM server and client test modules that use |
568 | triplets stored in a file. For details on the configuration see | |
569 | the scenario 'ikev2/rw-eap-sim-rsa'. | |
570 | ||
fb6d76cd | 571 | |
83e0d841 AS |
572 | strongswan-4.1.10 |
573 | ----------------- | |
574 | ||
575 | - Fixed error in the ordering of the certinfo_t records in the ocsp cache that | |
b6b90b68 | 576 | caused multiple entries of the same serial number to be created. |
83e0d841 | 577 | |
fdc7c943 MW |
578 | - Implementation of a simple EAP-MD5 module which provides CHAP |
579 | authentication. This may be interesting in conjunction with certificate | |
580 | based server authentication, as weak passwords can't be brute forced | |
581 | (in contradiction to traditional IKEv2 PSK). | |
582 | ||
583 | - A complete software based implementation of EAP-AKA, using algorithms | |
584 | specified in 3GPP2 (S.S0055). This implementation does not use an USIM, | |
585 | but reads the secrets from ipsec.secrets. Make sure to read eap_aka.h | |
586 | before using it. | |
587 | ||
588 | - Support for vendor specific EAP methods using Expanded EAP types. The | |
b6b90b68 | 589 | interface to EAP modules has been slightly changed, so make sure to |
fdc7c943 | 590 | check the changes if you're already rolling your own modules. |
83e0d841 | 591 | |
fb6d76cd | 592 | |
5076770c AS |
593 | strongswan-4.1.9 |
594 | ---------------- | |
595 | ||
800b3356 AS |
596 | - The default _updown script now dynamically inserts and removes ip6tables |
597 | firewall rules if leftfirewall=yes is set in IPv6 connections. New IPv6 | |
598 | net-net and roadwarrior (PSK/RSA) scenarios for both IKEv1 and IKEV2 were | |
599 | added. | |
5076770c | 600 | |
6f274c2a MW |
601 | - Implemented RFC4478 repeated authentication to force EAP/Virtual-IP clients |
602 | to reestablish an IKE_SA within a given timeframe. | |
603 | ||
604 | - strongSwan Manager supports configuration listing, initiation and termination | |
605 | of IKE and CHILD_SAs. | |
606 | ||
607 | - Fixes and improvements to multithreading code. | |
608 | ||
8b678ad4 | 609 | - IKEv2 plugins have been renamed to libcharon-* to avoid naming conflicts. |
b6b90b68 | 610 | Make sure to remove the old plugins in $libexecdir/ipsec, otherwise they get |
8b678ad4 | 611 | loaded twice. |
5076770c | 612 | |
83e0d841 | 613 | |
b82e8231 AS |
614 | strongswan-4.1.8 |
615 | ---------------- | |
616 | ||
5076770c | 617 | - Removed recursive pthread mutexes since uClibc doesn't support them. |
b82e8231 AS |
618 | |
619 | ||
a4a3632c AS |
620 | strongswan-4.1.7 |
621 | ---------------- | |
622 | ||
623 | - In NAT traversal situations and multiple queued Quick Modes, | |
624 | those pending connections inserted by auto=start after the | |
625 | port floating from 500 to 4500 were erronously deleted. | |
626 | ||
6e193274 | 627 | - Added a "forceencaps" connection parameter to enforce UDP encapsulation |
078b6008 | 628 | to surmount restrictive firewalls. NAT detection payloads are faked to |
6e193274 MW |
629 | simulate a NAT situation and trick the other peer into NAT mode (IKEv2 only). |
630 | ||
631 | - Preview of strongSwan Manager, a web based configuration and monitoring | |
632 | application. It uses a new XML control interface to query the IKEv2 daemon | |
633 | (see http://trac.strongswan.org/wiki/Manager). | |
634 | ||
635 | - Experimental SQLite configuration backend which will provide the configuration | |
636 | interface for strongSwan Manager in future releases. | |
637 | ||
638 | - Further improvements to MOBIKE support. | |
639 | ||
a4a3632c | 640 | |
3dcf9dbd AS |
641 | strongswan-4.1.6 |
642 | ---------------- | |
643 | ||
3eac4dfd AS |
644 | - Since some third party IKEv2 implementations run into |
645 | problems with strongSwan announcing MOBIKE capability per | |
646 | default, MOBIKE can be disabled on a per-connection-basis | |
647 | using the mobike=no option. Whereas mobike=no disables the | |
648 | sending of the MOBIKE_SUPPORTED notification and the floating | |
649 | to UDP port 4500 with the IKE_AUTH request even if no NAT | |
650 | situation has been detected, strongSwan will still support | |
651 | MOBIKE acting as a responder. | |
652 | ||
653 | - the default ipsec routing table plus its corresponding priority | |
654 | used for inserting source routes has been changed from 100 to 220. | |
655 | It can be configured using the --with-ipsec-routing-table and | |
b6b90b68 MW |
656 | --with-ipsec-routing-table-prio options. |
657 | ||
bdc0b55b AS |
658 | - the --enable-integrity-test configure option tests the |
659 | integrity of the libstrongswan crypto code during the charon | |
660 | startup. | |
b6b90b68 | 661 | |
3eac4dfd AS |
662 | - the --disable-xauth-vid configure option disables the sending |
663 | of the XAUTH vendor ID. This can be used as a workaround when | |
664 | interoperating with some Windows VPN clients that get into | |
665 | trouble upon reception of an XAUTH VID without eXtended | |
666 | AUTHentication having been configured. | |
b6b90b68 | 667 | |
f872f9d1 AS |
668 | - ipsec stroke now supports the rereadsecrets, rereadaacerts, |
669 | rereadacerts, and listacerts options. | |
3dcf9dbd AS |
670 | |
671 | ||
7ad634a2 AS |
672 | strongswan-4.1.5 |
673 | ---------------- | |
674 | ||
675 | - If a DNS lookup failure occurs when resolving right=%<FQDN> | |
676 | or right=<FQDN> combined with rightallowany=yes then the | |
677 | connection is not updated by ipsec starter thus preventing | |
678 | the disruption of an active IPsec connection. Only if the DNS | |
679 | lookup successfully returns with a changed IP address the | |
680 | corresponding connection definition is updated. | |
681 | ||
8f5b363c MW |
682 | - Routes installed by the keying daemons are now in a separate |
683 | routing table with the ID 100 to avoid conflicts with the main | |
684 | table. Route lookup for IKEv2 traffic is done in userspace to ignore | |
685 | routes installed for IPsec, as IKE traffic shouldn't get encapsulated. | |
686 | ||
7ad634a2 | 687 | |
e93c68ba AS |
688 | strongswan-4.1.4 |
689 | ---------------- | |
690 | ||
691 | - The pluto IKEv1 daemon now exhibits the same behaviour as its | |
692 | IKEv2 companion charon by inserting an explicit route via the | |
693 | _updown script only if a sourceip exists. This is admissible | |
694 | since routing through the IPsec tunnel is handled automatically | |
b7af55ac AS |
695 | by NETKEY's IPsec policies. As a consequence the left|rightnexthop |
696 | parameter is not required any more. | |
078ce348 AS |
697 | |
698 | - The new IKEv1 parameter right|leftallowany parameters helps to handle | |
699 | the case where both peers possess dynamic IP addresses that are | |
700 | usually resolved using DynDNS or a similar service. The configuration | |
701 | ||
702 | right=peer.foo.bar | |
703 | rightallowany=yes | |
704 | ||
705 | can be used by the initiator to start up a connection to a peer | |
706 | by resolving peer.foo.bar into the currently allocated IP address. | |
707 | Thanks to the rightallowany flag the connection behaves later on | |
708 | as | |
709 | ||
710 | right=%any | |
711 | ||
712 | so that the peer can rekey the connection as an initiator when his | |
1fbdab85 AS |
713 | IP address changes. An alternative notation is |
714 | ||
715 | right=%peer.foo.bar | |
716 | ||
717 | which will implicitly set rightallowany=yes. | |
718 | ||
719 | - ipsec starter now fails more gracefully in the presence of parsing | |
720 | errors. Flawed ca and conn section are discarded and pluto is started | |
721 | if non-fatal errors only were encountered. If right=%peer.foo.bar | |
722 | cannot be resolved by DNS then right=%any will be used so that passive | |
723 | connections as a responder are still possible. | |
078ce348 | 724 | |
a0a0bdd7 AS |
725 | - The new pkcs11initargs parameter that can be placed in the |
726 | setup config section of /etc/ipsec.conf allows the definition | |
727 | of an argument string that is used with the PKCS#11 C_Initialize() | |
728 | function. This non-standard feature is required by the NSS softoken | |
729 | library. This patch was contributed by Robert Varga. | |
b6b90b68 | 730 | |
a0a0bdd7 AS |
731 | - Fixed a bug in ipsec starter introduced by strongswan-2.8.5 |
732 | which caused a segmentation fault in the presence of unknown | |
733 | or misspelt keywords in ipsec.conf. This bug fix was contributed | |
734 | by Robert Varga. | |
735 | ||
e3606f2b MW |
736 | - Partial support for MOBIKE in IKEv2. The initiator acts on interface/ |
737 | address configuration changes and updates IKE and IPsec SAs dynamically. | |
e93c68ba | 738 | |
06651827 | 739 | |
a3354a69 AS |
740 | strongswan-4.1.3 |
741 | ---------------- | |
742 | ||
b6b90b68 | 743 | - IKEv2 peer configuration selection now can be based on a given |
35d4809c AS |
744 | certification authority using the rightca= statement. |
745 | ||
746 | - IKEv2 authentication based on RSA signatures now can handle multiple | |
41e16cf4 AS |
747 | certificates issued for a given peer ID. This allows a smooth transition |
748 | in the case of a peer certificate renewal. | |
a3354a69 | 749 | |
998ca0ea MW |
750 | - IKEv2: Support for requesting a specific virtual IP using leftsourceip on the |
751 | client and returning requested virtual IPs using rightsourceip=%config | |
752 | on the server. If the server does not support configuration payloads, the | |
753 | client enforces its leftsourceip parameter. | |
754 | ||
755 | - The ./configure options --with-uid/--with-gid allow pluto and charon | |
756 | to drop their privileges to a minimum and change to an other UID/GID. This | |
757 | improves the systems security, as a possible intruder may only get the | |
758 | CAP_NET_ADMIN capability. | |
759 | ||
b6b90b68 | 760 | - Further modularization of charon: Pluggable control interface and |
998ca0ea MW |
761 | configuration backend modules provide extensibility. The control interface |
762 | for stroke is included, and further interfaces using DBUS (NetworkManager) | |
763 | or XML are on the way. A backend for storing configurations in the daemon | |
b6b90b68 | 764 | is provided and more advanced backends (using e.g. a database) are trivial |
998ca0ea | 765 | to implement. |
a3354a69 | 766 | |
41e16cf4 AS |
767 | - Fixed a compilation failure in libfreeswan occuring with Linux kernel |
768 | headers > 2.6.17. | |
769 | ||
770 | ||
8ea7b96f AS |
771 | strongswan-4.1.2 |
772 | ---------------- | |
773 | ||
e23d98a7 | 774 | - Support for an additional Diffie-Hellman exchange when creating/rekeying |
37fb0355 MW |
775 | a CHILD_SA in IKEv2 (PFS). PFS is enabled when the proposal contains a |
776 | DH group (e.g. "esp=aes128-sha1-modp1536"). Further, DH group negotiation | |
777 | is implemented properly for rekeying. | |
778 | ||
779 | - Support for the AES-XCBC-96 MAC algorithm for IPsec SAs when using IKEv2 | |
780 | (requires linux >= 2.6.20). It is enabled using e.g. "esp=aes256-aesxcbc". | |
781 | ||
d931f465 MW |
782 | - Working IPv4-in-IPv6 and IPv6-in-IPv4 tunnels for linux >= 2.6.21. |
783 | ||
37fb0355 MW |
784 | - Added support for EAP modules which do not establish an MSK. |
785 | ||
dfbe2a0f | 786 | - Removed the dependencies from the /usr/include/linux/ headers by |
9f78f957 | 787 | including xfrm.h, ipsec.h, and pfkeyv2.h in the distribution. |
b6b90b68 | 788 | |
9f78f957 AS |
789 | - crlNumber is now listed by ipsec listcrls |
790 | ||
8ea7b96f AS |
791 | - The xauth_modules.verify_secret() function now passes the |
792 | connection name. | |
793 | ||
e23d98a7 | 794 | |
ed284399 MW |
795 | strongswan-4.1.1 |
796 | ---------------- | |
797 | ||
798 | - Server side cookie support. If to may IKE_SAs are in CONNECTING state, | |
799 | cookies are enabled and protect against DoS attacks with faked source | |
800 | addresses. Number of IKE_SAs in CONNECTING state is also limited per | |
801 | peer address to avoid resource exhaustion. IKE_SA_INIT messages are | |
802 | compared to properly detect retransmissions and incoming retransmits are | |
803 | detected even if the IKE_SA is blocked (e.g. doing OCSP fetches). | |
804 | ||
db88e37d AS |
805 | - The IKEv2 daemon charon now supports dynamic http- and ldap-based CRL |
806 | fetching enabled by crlcheckinterval > 0 and caching fetched CRLs | |
807 | enabled by cachecrls=yes. | |
808 | ||
3b4f7d92 AS |
809 | - Added the configuration options --enable-nat-transport which enables |
810 | the potentially insecure NAT traversal for IPsec transport mode and | |
811 | --disable-vendor-id which disables the sending of the strongSwan | |
812 | vendor ID. | |
813 | ||
814 | - Fixed a long-standing bug in the pluto IKEv1 daemon which caused | |
815 | a segmentation fault if a malformed payload was detected in the | |
816 | IKE MR2 message and pluto tried to send an encrypted notification | |
817 | message. | |
818 | ||
46b9ff68 AS |
819 | - Added the NATT_IETF_02_N Vendor ID in order to support IKEv1 connections |
820 | with Windows 2003 Server which uses a wrong VID hash. | |
821 | ||
3b4f7d92 | 822 | |
34bbd0c3 | 823 | strongswan-4.1.0 |
cd3958f8 AS |
824 | ---------------- |
825 | ||
826 | - Support of SHA2_384 hash function for protecting IKEv1 | |
827 | negotiations and support of SHA2 signatures in X.509 certificates. | |
828 | ||
829 | - Fixed a serious bug in the computation of the SHA2-512 HMAC | |
830 | function. Introduced automatic self-test of all IKEv1 hash | |
831 | and hmac functions during pluto startup. Failure of a self-test | |
832 | currently issues a warning only but does not exit pluto [yet]. | |
833 | ||
9b45443d MW |
834 | - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2. |
835 | ||
c5d0fbb6 | 836 | - Full support of CA information sections. ipsec listcainfos |
b6b90b68 | 837 | now shows all collected crlDistributionPoints and OCSP |
c5d0fbb6 AS |
838 | accessLocations. |
839 | ||
69ed04bf AS |
840 | - Support of the Online Certificate Status Protocol (OCSP) for IKEv2. |
841 | This feature requires the HTTP fetching capabilities of the libcurl | |
842 | library which must be enabled by setting the --enable-http configure | |
843 | option. | |
844 | ||
9b45443d MW |
845 | - Refactored core of the IKEv2 message processing code, allowing better |
846 | code reuse and separation. | |
847 | ||
848 | - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration | |
849 | payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted | |
850 | by the requestor and installed in a resolv.conf file. | |
851 | ||
852 | - The IKEv2 daemon charon installs a route for each IPsec policy to use | |
853 | the correct source address even if an application does not explicitly | |
854 | specify it. | |
855 | ||
856 | - Integrated the EAP framework into charon which loads pluggable EAP library | |
857 | modules. The ipsec.conf parameter authby=eap initiates EAP authentication | |
858 | on the client side, while the "eap" parameter on the server side defines | |
859 | the EAP method to use for client authentication. | |
860 | A generic client side EAP-Identity module and an EAP-SIM authentication | |
861 | module using a third party card reader implementation are included. | |
862 | ||
863 | - Added client side support for cookies. | |
864 | ||
865 | - Integrated the fixes done at the IKEv2 interoperability bakeoff, including | |
866 | strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor | |
867 | fixes to enhance interoperability with other implementations. | |
cd3958f8 | 868 | |
e23d98a7 | 869 | |
1c266d7d AS |
870 | strongswan-4.0.7 |
871 | ---------------- | |
872 | ||
6fdf5f44 AS |
873 | - strongSwan now interoperates with the NCP Secure Entry Client, |
874 | the Shrew Soft VPN Client, and the Cisco VPN client, doing both | |
875 | XAUTH and Mode Config. | |
1c266d7d AS |
876 | |
877 | - UNITY attributes are now recognized and UNITY_BANNER is set | |
878 | to a default string. | |
879 | ||
880 | ||
2b4405a3 MW |
881 | strongswan-4.0.6 |
882 | ---------------- | |
883 | ||
e38a15d4 AS |
884 | - IKEv1: Support for extended authentication (XAUTH) in combination |
885 | with ISAKMP Main Mode RSA or PSK authentication. Both client and | |
886 | server side were implemented. Handling of user credentials can | |
887 | be done by a run-time loadable XAUTH module. By default user | |
b6b90b68 MW |
888 | credentials are stored in ipsec.secrets. |
889 | ||
2b4405a3 MW |
890 | - IKEv2: Support for reauthentication when rekeying |
891 | ||
5903179b | 892 | - IKEv2: Support for transport mode |
af87afed | 893 | |
5903179b | 894 | - fixed a lot of bugs related to byte order |
2b4405a3 | 895 | |
5903179b | 896 | - various other bugfixes |
2b4405a3 MW |
897 | |
898 | ||
0cd645d2 AS |
899 | strongswan-4.0.5 |
900 | ---------------- | |
901 | ||
902 | - IKEv1: Implementation of ModeConfig push mode via the new connection | |
903 | keyword modeconfig=push allows interoperability with Cisco VPN gateways. | |
904 | ||
905 | - IKEv1: The command ipsec statusall now shows "DPD active" for all | |
906 | ISAKMP SAs that are under active Dead Peer Detection control. | |
907 | ||
908 | - IKEv2: Charon's logging and debugging framework has been completely rewritten. | |
909 | Instead of logger, special printf() functions are used to directly | |
910 | print objects like hosts (%H) identifications (%D), certificates (%Q), | |
911 | etc. The number of debugging levels have been reduced to: | |
03bf883d | 912 | |
0cd645d2 | 913 | 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private) |
03bf883d | 914 | |
0cd645d2 AS |
915 | The debugging levels can either be specified statically in ipsec.conf as |
916 | ||
917 | config setup | |
03bf883d | 918 | charondebug="lib 1, cfg 3, net 2" |
0cd645d2 | 919 | |
03bf883d | 920 | or changed at runtime via stroke as |
0cd645d2 | 921 | |
03bf883d | 922 | ipsec stroke loglevel cfg 2 |
0cd645d2 AS |
923 | |
924 | ||
48dc3934 MW |
925 | strongswan-4.0.4 |
926 | ---------------- | |
927 | ||
928 | - Implemented full support for IPv6-in-IPv6 tunnels. | |
929 | ||
930 | - Added configuration options for dead peer detection in IKEv2. dpd_action | |
931 | types "clear", "hold" and "restart" are supported. The dpd_timeout | |
932 | value is not used, as the normal retransmission policy applies to | |
933 | detect dead peers. The dpd_delay parameter enables sending of empty | |
934 | informational message to detect dead peers in case of inactivity. | |
935 | ||
936 | - Added support for preshared keys in IKEv2. PSK keys configured in | |
937 | ipsec.secrets are loaded. The authby parameter specifies the authentication | |
938 | method to authentificate ourself, the other peer may use PSK or RSA. | |
939 | ||
940 | - Changed retransmission policy to respect the keyingtries parameter. | |
941 | ||
112ad7c3 AS |
942 | - Added private key decryption. PEM keys encrypted with AES-128/192/256 |
943 | or 3DES are supported. | |
48dc3934 MW |
944 | |
945 | - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to | |
946 | encrypt IKE traffic. | |
947 | ||
948 | - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates | |
949 | signed with such a hash algorithm. | |
950 | ||
951 | - Added initial support for updown scripts. The actions up-host/client and | |
952 | down-host/client are executed. The leftfirewall=yes parameter | |
953 | uses the default updown script to insert dynamic firewall rules, a custom | |
954 | updown script may be specified with the leftupdown parameter. | |
955 | ||
956 | ||
a1310b6b MW |
957 | strongswan-4.0.3 |
958 | ---------------- | |
959 | ||
960 | - Added support for the auto=route ipsec.conf parameter and the | |
b6b90b68 MW |
961 | ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and |
962 | CHILD_SAs dynamically on demand when traffic is detected by the | |
a1310b6b MW |
963 | kernel. |
964 | ||
965 | - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter. | |
966 | As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only | |
967 | new keys are generated using perfect forward secrecy. An optional flag | |
968 | which enforces reauthentication will be implemented later. | |
969 | ||
b425d998 AS |
970 | - "sha" and "sha1" are now treated as synonyms in the ike= and esp= |
971 | algorithm configuration statements. | |
972 | ||
973 | ||
bf4df11f AS |
974 | strongswan-4.0.2 |
975 | ---------------- | |
976 | ||
623d3dcf AS |
977 | - Full X.509 certificate trust chain verification has been implemented. |
978 | End entity certificates can be exchanged via CERT payloads. The current | |
979 | default is leftsendcert=always, since CERTREQ payloads are not supported | |
980 | yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls. | |
efa40c11 | 981 | |
b6b90b68 | 982 | - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2 |
efa40c11 | 983 | would offer more possibilities for traffic selection, but the Linux kernel |
b6b90b68 | 984 | currently does not support it. That's why we stick with these simple |
efa40c11 MW |
985 | ipsec.conf rules for now. |
986 | ||
623d3dcf AS |
987 | - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no |
988 | IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear, | |
989 | dpddelay=60s). | |
990 | ||
efa40c11 MW |
991 | - Initial NAT traversal support in IKEv2. Charon includes NAT detection |
992 | notify payloads to detect NAT routers between the peers. It switches | |
993 | to port 4500, uses UDP encapsulated ESP packets, handles peer address | |
994 | changes gracefully and sends keep alive message periodically. | |
995 | ||
b6b90b68 MW |
996 | - Reimplemented IKE_SA state machine for charon, which allows simultaneous |
997 | rekeying, more shared code, cleaner design, proper retransmission | |
efa40c11 MW |
998 | and a more extensible code base. |
999 | ||
cfd8b27f AS |
1000 | - The mixed PSK/RSA roadwarrior detection capability introduced by the |
1001 | strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal | |
1002 | payloads by the responder right before any defined IKE Main Mode state had | |
1003 | been established. Although any form of bad proposal syntax was being correctly | |
1004 | detected by the payload parser, the subsequent error handler didn't check | |
1005 | the state pointer before logging current state information, causing an | |
1006 | immediate crash of the pluto keying daemon due to a NULL pointer. | |
1007 | ||
bf4df11f | 1008 | |
7e81e975 MW |
1009 | strongswan-4.0.1 |
1010 | ---------------- | |
1011 | ||
b6b90b68 | 1012 | - Added algorithm selection to charon: New default algorithms for |
c15c3d4b MW |
1013 | ike=aes128-sha-modp2048, as both daemons support it. The default |
1014 | for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles | |
1015 | the ike/esp parameter the same way as pluto. As this syntax does | |
b6b90b68 | 1016 | not allow specification of a pseudo random function, the same |
c15c3d4b MW |
1017 | algorithm as for integrity is used (currently sha/md5). Supported |
1018 | algorithms for IKE: | |
1019 | Encryption: aes128, aes192, aes256 | |
1020 | Integrity/PRF: md5, sha (using hmac) | |
1021 | DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192 | |
1022 | and for ESP: | |
b6b90b68 | 1023 | Encryption: aes128, aes192, aes256, 3des, blowfish128, |
c15c3d4b MW |
1024 | blowfish192, blowfish256 |
1025 | Integrity: md5, sha1 | |
1026 | More IKE encryption algorithms will come after porting libcrypto into | |
b6b90b68 | 1027 | libstrongswan. |
f2c2d395 | 1028 | |
c15c3d4b MW |
1029 | - initial support for rekeying CHILD_SAs using IKEv2. Currently no |
1030 | perfect forward secrecy is used. The rekeying parameters rekey, | |
22ff6f57 | 1031 | rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported |
c15c3d4b MW |
1032 | when using IKEv2. WARNING: charon currently is unable to handle |
1033 | simultaneous rekeying. To avoid such a situation, use a large | |
1034 | rekeyfuzz, or even better, set rekey=no on one peer. | |
22ff6f57 | 1035 | |
7e81e975 MW |
1036 | - support for host2host, net2net, host2net (roadwarrior) tunnels |
1037 | using predefined RSA certificates (see uml scenarios for | |
1038 | configuration examples). | |
1039 | ||
f2c2d395 MW |
1040 | - new build environment featuring autotools. Features such |
1041 | as HTTP, LDAP and smartcard support may be enabled using | |
b6b90b68 | 1042 | the ./configure script. Changing install directories |
f2c2d395 MW |
1043 | is possible, too. See ./configure --help for more details. |
1044 | ||
22ff6f57 MW |
1045 | - better integration of charon with ipsec starter, which allows |
1046 | (almost) transparent operation with both daemons. charon | |
1047 | handles ipsec commands up, down, status, statusall, listall, | |
1048 | listcerts and allows proper load, reload and delete of connections | |
1049 | via ipsec starter. | |
1050 | ||
b425d998 | 1051 | |
9820c0e2 MW |
1052 | strongswan-4.0.0 |
1053 | ---------------- | |
1054 | ||
1055 | - initial support of the IKEv2 protocol. Connections in | |
b6b90b68 | 1056 | ipsec.conf designated by keyexchange=ikev2 are negotiated |
9820c0e2 MW |
1057 | by the new IKEv2 charon keying daemon whereas those marked |
1058 | by keyexchange=ikev1 or the default keyexchange=ike are | |
1059 | handled thy the IKEv1 pluto keying daemon. Currently only | |
1060 | a limited subset of functions are available with IKEv2 | |
1061 | (Default AES encryption, authentication based on locally | |
1062 | imported X.509 certificates, unencrypted private RSA keys | |
1063 | in PKCS#1 file format, limited functionality of the ipsec | |
1064 | status command). | |
1065 | ||
1066 | ||
997358a6 MW |
1067 | strongswan-2.7.0 |
1068 | ---------------- | |
1069 | ||
1070 | - the dynamic iptables rules from the _updown_x509 template | |
1071 | for KLIPS and the _updown_policy template for NETKEY have | |
1072 | been merged into the default _updown script. The existing | |
1073 | left|rightfirewall keyword causes the automatic insertion | |
1074 | and deletion of ACCEPT rules for tunneled traffic upon | |
1075 | the successful setup and teardown of an IPsec SA, respectively. | |
1076 | left|rightfirwall can be used with KLIPS under any Linux 2.4 | |
1077 | kernel or with NETKEY under a Linux kernel version >= 2.6.16 | |
1078 | in conjuction with iptables >= 1.3.5. For NETKEY under a Linux | |
1079 | kernel version < 2.6.16 which does not support IPsec policy | |
1080 | matching yet, please continue to use a copy of the _updown_espmark | |
1081 | template loaded via the left|rightupdown keyword. | |
1082 | ||
1083 | - a new left|righthostaccess keyword has been introduced which | |
1084 | can be used in conjunction with left|rightfirewall and the | |
1085 | default _updown script. By default leftfirewall=yes inserts | |
1086 | a bi-directional iptables FORWARD rule for a local client network | |
1087 | with a netmask different from 255.255.255.255 (single host). | |
1088 | This does not allow to access the VPN gateway host via its | |
1089 | internal network interface which is part of the client subnet | |
1090 | because an iptables INPUT and OUTPUT rule would be required. | |
1091 | lefthostaccess=yes will cause this additional ACCEPT rules to | |
b6b90b68 | 1092 | be inserted. |
997358a6 MW |
1093 | |
1094 | - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal | |
1095 | payload is preparsed in order to find out whether the roadwarrior | |
1096 | requests PSK or RSA so that a matching connection candidate can | |
1097 | be found. | |
1098 | ||
1099 | ||
1100 | strongswan-2.6.4 | |
1101 | ---------------- | |
1102 | ||
1103 | - the new _updown_policy template allows ipsec policy based | |
1104 | iptables firewall rules. Required are iptables version | |
1105 | >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes | |
b6b90b68 | 1106 | the _updown_espmark template, so that no INPUT mangle rules |
997358a6 MW |
1107 | are required any more. |
1108 | ||
1109 | - added support of DPD restart mode | |
1110 | ||
1111 | - ipsec starter now allows the use of wildcards in include | |
1112 | statements as e.g. in "include /etc/my_ipsec/*.conf". | |
1113 | Patch courtesy of Matthias Haas. | |
1114 | ||
1115 | - the Netscape OID 'employeeNumber' is now recognized and can be | |
1116 | used as a Relative Distinguished Name in certificates. | |
1117 | ||
1118 | ||
1119 | strongswan-2.6.3 | |
1120 | ---------------- | |
1121 | ||
b6b90b68 | 1122 | - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec |
997358a6 MW |
1123 | command and not of ipsec setup any more. |
1124 | ||
1125 | - ipsec starter now supports AH authentication in conjunction with | |
1126 | ESP encryption. AH authentication is configured in ipsec.conf | |
1127 | via the auth=ah parameter. | |
b6b90b68 | 1128 | |
997358a6 MW |
1129 | - The command ipsec scencrypt|scdecrypt <args> is now an alias for |
1130 | ipsec whack --scencrypt|scdecrypt <args>. | |
1131 | ||
1132 | - get_sa_info() now determines for the native netkey IPsec stack | |
1133 | the exact time of the last use of an active eroute. This information | |
1134 | is used by the Dead Peer Detection algorithm and is also displayed by | |
1135 | the ipsec status command. | |
b6b90b68 | 1136 | |
997358a6 MW |
1137 | |
1138 | strongswan-2.6.2 | |
1139 | ---------------- | |
1140 | ||
1141 | - running under the native Linux 2.6 IPsec stack, the function | |
1142 | get_sa_info() is called by ipsec auto --status to display the current | |
1143 | number of transmitted bytes per IPsec SA. | |
1144 | ||
1145 | - get_sa_info() is also used by the Dead Peer Detection process to detect | |
1146 | recent ESP activity. If ESP traffic was received from the peer within | |
1147 | the last dpd_delay interval then no R_Y_THERE notification must be sent. | |
1148 | ||
1149 | - strongSwan now supports the Relative Distinguished Name "unstructuredName" | |
1150 | in ID_DER_ASN1_DN identities. The following notations are possible: | |
1151 | ||
1152 | rightid="unstructuredName=John Doe" | |
1153 | rightid="UN=John Doe" | |
1154 | ||
1155 | - fixed a long-standing bug which caused PSK-based roadwarrior connections | |
1156 | to segfault in the function id.c:same_id() called by keys.c:get_secret() | |
1157 | if an FQDN, USER_FQDN, or Key ID was defined, as in the following example. | |
1158 | ||
1159 | conn rw | |
1160 | right=%any | |
1161 | rightid=@foo.bar | |
1162 | authby=secret | |
1163 | ||
1164 | - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall). | |
1165 | ||
1166 | - ipsec starter didn't set host_addr and client.addr ports in whack msg. | |
1167 | ||
1168 | - in order to guarantee backwards-compatibility with the script-based | |
1169 | auto function (e.g. auto --replace), the ipsec starter scripts stores | |
1170 | the defaultroute information in the temporary file /var/run/ipsec.info. | |
1171 | ||
1172 | - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH | |
1173 | Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config | |
1174 | servers. | |
1175 | ||
1176 | - the ipsec starter now also recognizes the parameters authby=never and | |
1177 | type=passthrough|pass|drop|reject. | |
1178 | ||
1179 | ||
1180 | strongswan-2.6.1 | |
1181 | ---------------- | |
1182 | ||
1183 | - ipsec starter now supports the also parameter which allows | |
1184 | a modular structure of the connection definitions. Thus | |
1185 | "ipsec start" is now ready to replace "ipsec setup". | |
1186 | ||
1187 | ||
1188 | strongswan-2.6.0 | |
1189 | ---------------- | |
1190 | ||
1191 | - Mathieu Lafon's popular ipsec starter tool has been added to the | |
1192 | strongSwan distribution. Many thanks go to Stephan Scholz from astaro | |
1193 | for his integration work. ipsec starter is a C program which is going | |
1194 | to replace the various shell and awk starter scripts (setup, _plutoload, | |
1195 | _plutostart, _realsetup, _startklips, _confread, and auto). Since | |
1196 | ipsec.conf is now parsed only once, the starting of multiple tunnels is | |
1197 | accelerated tremedously. | |
1198 | ||
1199 | - Added support of %defaultroute to the ipsec starter. If the IP address | |
b6b90b68 | 1200 | changes, a HUP signal to the ipsec starter will automatically |
997358a6 MW |
1201 | reload pluto's connections. |
1202 | ||
1203 | - moved most compile time configurations from pluto/Makefile to | |
1204 | Makefile.inc by defining the options USE_LIBCURL, USE_LDAP, | |
1205 | USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE. | |
1206 | ||
1207 | - removed the ipsec verify and ipsec newhostkey commands | |
1208 | ||
1209 | - fixed some 64-bit issues in formatted print statements | |
1210 | ||
1211 | - The scepclient functionality implementing the Simple Certificate | |
1212 | Enrollment Protocol (SCEP) is nearly complete but hasn't been | |
1213 | documented yet. | |
1214 | ||
1215 | ||
1216 | strongswan-2.5.7 | |
1217 | ---------------- | |
1218 | ||
1219 | - CA certicates are now automatically loaded from a smartcard | |
1220 | or USB crypto token and appear in the ipsec auto --listcacerts | |
1221 | listing. | |
1222 | ||
1223 | ||
1224 | strongswan-2.5.6 | |
1225 | ---------------- | |
1226 | ||
1227 | - when using "ipsec whack --scencrypt <data>" with a PKCS#11 | |
1228 | library that does not support the C_Encrypt() Cryptoki | |
1229 | function (e.g. OpenSC), the RSA encryption is done in | |
1230 | software using the public key fetched from the smartcard. | |
1231 | ||
b6b90b68 | 1232 | - The scepclient function now allows to define the |
997358a6 MW |
1233 | validity of a self-signed certificate using the --days, |
1234 | --startdate, and --enddate options. The default validity | |
1235 | has been changed from one year to five years. | |
1236 | ||
1237 | ||
1238 | strongswan-2.5.5 | |
1239 | ---------------- | |
1240 | ||
1241 | - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11 | |
1242 | interface to other applications for RSA encryption and decryption | |
1243 | via the whack interface. Notation: | |
1244 | ||
1245 | ipsec whack --scencrypt <data> | |
1246 | [--inbase 16|hex|64|base64|256|text|ascii] | |
1247 | [--outbase 16|hex|64|base64|256|text|ascii] | |
1248 | [--keyid <keyid>] | |
1249 | ||
1250 | ipsec whack --scdecrypt <data> | |
1251 | [--inbase 16|hex|64|base64|256|text|ascii] | |
1252 | [--outbase 16|hex|64|base64|256|text|ascii] | |
1253 | [--keyid <keyid>] | |
1254 | ||
b6b90b68 | 1255 | The default setting for inbase and outbase is hex. |
997358a6 MW |
1256 | |
1257 | The new proxy interface can be used for securing symmetric | |
1258 | encryption keys required by the cryptoloop or dm-crypt | |
1259 | disk encryption schemes, especially in the case when | |
1260 | pkcs11keepstate=yes causes pluto to lock the pkcs11 slot | |
1261 | permanently. | |
1262 | ||
1263 | - if the file /etc/ipsec.secrets is lacking during the startup of | |
1264 | pluto then the root-readable file /etc/ipsec.d/private/myKey.der | |
1265 | containing a 2048 bit RSA private key and a matching self-signed | |
1266 | certificate stored in the file /etc/ipsec.d/certs/selfCert.der | |
1267 | is automatically generated by calling the function | |
1268 | ||
1269 | ipsec scepclient --out pkcs1 --out cert-self | |
1270 | ||
1271 | scepclient was written by Jan Hutter and Martin Willi, students | |
1272 | at the University of Applied Sciences in Rapperswil, Switzerland. | |
1273 | ||
1274 | ||
1275 | strongswan-2.5.4 | |
1276 | ---------------- | |
1277 | ||
1278 | - the current extension of the PKCS#7 framework introduced | |
1279 | a parsing error in PKCS#7 wrapped X.509 certificates that are | |
1280 | e.g. transmitted by Windows XP when multi-level CAs are used. | |
1281 | the parsing syntax has been fixed. | |
1282 | ||
1283 | - added a patch by Gerald Richter which tolerates multiple occurrences | |
1284 | of the ipsec0 interface when using KLIPS. | |
1285 | ||
1286 | ||
1287 | strongswan-2.5.3 | |
1288 | ---------------- | |
1289 | ||
1290 | - with gawk-3.1.4 the word "default2 has become a protected | |
1291 | keyword for use in switch statements and cannot be used any | |
1292 | more in the strongSwan scripts. This problem has been | |
1293 | solved by renaming "default" to "defaults" and "setdefault" | |
1294 | in the scripts _confread and auto, respectively. | |
1295 | ||
1296 | - introduced the parameter leftsendcert with the values | |
1297 | ||
1298 | always|yes (the default, always send a cert) | |
1299 | ifasked (send the cert only upon a cert request) | |
1300 | never|no (never send a cert, used for raw RSA keys and | |
b6b90b68 | 1301 | self-signed certs) |
997358a6 MW |
1302 | |
1303 | - fixed the initialization of the ESP key length to a default of | |
1304 | 128 bits in the case that the peer does not send a key length | |
1305 | attribute for AES encryption. | |
1306 | ||
1307 | - applied Herbert Xu's uniqueIDs patch | |
1308 | ||
1309 | - applied Herbert Xu's CLOEXEC patches | |
1310 | ||
1311 | ||
1312 | strongswan-2.5.2 | |
1313 | ---------------- | |
1314 | ||
1315 | - CRLs can now be cached also in the case when the issuer's | |
1316 | certificate does not contain a subjectKeyIdentifier field. | |
1317 | In that case the subjectKeyIdentifier is computed by pluto as the | |
1318 | 160 bit SHA-1 hash of the issuer's public key in compliance | |
1319 | with section 4.2.1.2 of RFC 3280. | |
1320 | ||
1321 | - Fixed a bug introduced by strongswan-2.5.1 which eliminated | |
1322 | not only multiple Quick Modes of a given connection but also | |
1323 | multiple connections between two security gateways. | |
1324 | ||
1325 | ||
1326 | strongswan-2.5.1 | |
1327 | ---------------- | |
1328 | ||
1329 | - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute | |
1330 | installed either by setting auto=route in ipsec.conf or by | |
1331 | a connection put into hold, generates an XFRM_AQUIRE event | |
1332 | for each packet that wants to use the not-yet exisiting | |
1333 | tunnel. Up to now each XFRM_AQUIRE event led to an entry in | |
1334 | the Quick Mode queue, causing multiple IPsec SA to be | |
1335 | established in rapid succession. Starting with strongswan-2.5.1 | |
1336 | only a single IPsec SA is established per host-pair connection. | |
1337 | ||
1338 | - Right after loading the PKCS#11 module, all smartcard slots are | |
1339 | searched for certificates. The result can be viewed using | |
1340 | the command | |
1341 | ||
1342 | ipsec auto --listcards | |
1343 | ||
1344 | The certificate objects found in the slots are numbered | |
1345 | starting with #1, #2, etc. This position number can be used to address | |
1346 | certificates (leftcert=%smartcard) and keys (: PIN %smartcard) | |
1347 | in ipsec.conf and ipsec.secrets, respectively: | |
1348 | ||
1349 | %smartcard (selects object #1) | |
1350 | %smartcard#1 (selects object #1) | |
1351 | %smartcard#3 (selects object #3) | |
1352 | ||
1353 | As an alternative the existing retrieval scheme can be used: | |
1354 | ||
1355 | %smartcard:45 (selects object with id=45) | |
1356 | %smartcard0 (selects first object in slot 0) | |
1357 | %smartcard4:45 (selects object in slot 4 with id=45) | |
1358 | ||
1359 | - Depending on the settings of CKA_SIGN and CKA_DECRYPT | |
1360 | private key flags either C_Sign() or C_Decrypt() is used | |
1361 | to generate a signature. | |
1362 | ||
1363 | - The output buffer length parameter siglen in C_Sign() | |
1364 | is now initialized to the actual size of the output | |
1365 | buffer prior to the function call. This fixes the | |
1366 | CKR_BUFFER_TOO_SMALL error that could occur when using | |
1367 | the OpenSC PKCS#11 module. | |
1368 | ||
1369 | - Changed the initialization of the PKCS#11 CK_MECHANISM in | |
1370 | C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }. | |
1371 | ||
1372 | - Refactored the RSA public/private key code and transferred it | |
1373 | from keys.c to the new pkcs1.c file as a preparatory step | |
1374 | towards the release of the SCEP client. | |
1375 | ||
1376 | ||
1377 | strongswan-2.5.0 | |
1378 | ---------------- | |
1379 | ||
1380 | - The loading of a PKCS#11 smartcard library module during | |
1381 | runtime does not require OpenSC library functions any more | |
1382 | because the corresponding code has been integrated into | |
1383 | smartcard.c. Also the RSAREF pkcs11 header files have been | |
1384 | included in a newly created pluto/rsaref directory so that | |
1385 | no external include path has to be defined any longer. | |
1386 | ||
1387 | - A long-awaited feature has been implemented at last: | |
1388 | The local caching of CRLs fetched via HTTP or LDAP, activated | |
1389 | by the parameter cachecrls=yes in the config setup section | |
1390 | of ipsec.conf. The dynamically fetched CRLs are stored under | |
1391 | a unique file name containing the issuer's subjectKeyID | |
1392 | in /etc/ipsec.d/crls. | |
b6b90b68 | 1393 | |
997358a6 MW |
1394 | - Applied a one-line patch courtesy of Michael Richardson |
1395 | from the Openswan project which fixes the kernel-oops | |
1396 | in KLIPS when an snmp daemon is running on the same box. | |
1397 | ||
1398 | ||
1399 | strongswan-2.4.4 | |
1400 | ---------------- | |
1401 | ||
1402 | - Eliminated null length CRL distribution point strings. | |
1403 | ||
1404 | - Fixed a trust path evaluation bug introduced with 2.4.3 | |
1405 | ||
1406 | ||
1407 | strongswan-2.4.3 | |
1408 | ---------------- | |
1409 | ||
1410 | - Improved the joint OCSP / CRL revocation policy. | |
1411 | OCSP responses have precedence over CRL entries. | |
1412 | ||
1413 | - Introduced support of CRLv2 reason codes. | |
1414 | ||
1415 | - Fixed a bug with key-pad equipped readers which caused | |
1416 | pluto to prompt for the pin via the console when the first | |
1417 | occasion to enter the pin via the key-pad was missed. | |
1418 | ||
1419 | - When pluto is built with LDAP_V3 enabled, the library | |
1420 | liblber required by newer versions of openldap is now | |
1421 | included. | |
1422 | ||
1423 | ||
1424 | strongswan-2.4.2 | |
1425 | ---------------- | |
1426 | ||
1427 | - Added the _updown_espmark template which requires all | |
1428 | incoming ESP traffic to be marked with a default mark | |
1429 | value of 50. | |
b6b90b68 | 1430 | |
997358a6 MW |
1431 | - Introduced the pkcs11keepstate parameter in the config setup |
1432 | section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11 | |
b6b90b68 | 1433 | session and login states are kept as long as possible during |
997358a6 MW |
1434 | the lifetime of pluto. This means that a PIN entry via a key |
1435 | pad has to be done only once. | |
1436 | ||
1437 | - Introduced the pkcs11module parameter in the config setup | |
1438 | section of ipsec.conf which specifies the PKCS#11 module | |
1439 | to be used with smart cards. Example: | |
b6b90b68 | 1440 | |
997358a6 | 1441 | pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo |
b6b90b68 | 1442 | |
997358a6 MW |
1443 | - Added support of smartcard readers equipped with a PIN pad. |
1444 | ||
1445 | - Added patch by Jay Pfeifer which detects when netkey | |
1446 | modules have been statically built into the Linux 2.6 kernel. | |
1447 | ||
1448 | - Added two patches by Herbert Xu. The first uses ip xfrm | |
1449 | instead of setkey to flush the IPsec policy database. The | |
1450 | second sets the optional flag in inbound IPComp SAs only. | |
b6b90b68 | 1451 | |
997358a6 MW |
1452 | - Applied Ulrich Weber's patch which fixes an interoperability |
1453 | problem between native IPsec and KLIPS systems caused by | |
1454 | setting the replay window to 32 instead of 0 for ipcomp. | |
1455 | ||
1456 | ||
1457 | strongswan-2.4.1 | |
1458 | ---------------- | |
1459 | ||
1460 | - Fixed a bug which caused an unwanted Mode Config request | |
1461 | to be initiated in the case where "right" was used to denote | |
1462 | the local side in ipsec.conf and "left" the remote side, | |
1463 | contrary to the recommendation that "right" be remote and | |
1464 | "left" be"local". | |
1465 | ||
1466 | ||
1467 | strongswan-2.4.0a | |
1468 | ----------------- | |
1469 | ||
1470 | - updated Vendor ID to strongSwan-2.4.0 | |
1471 | ||
1472 | - updated copyright statement to include David Buechi and | |
1473 | Michael Meier | |
b6b90b68 MW |
1474 | |
1475 | ||
997358a6 MW |
1476 | strongswan-2.4.0 |
1477 | ---------------- | |
1478 | ||
1479 | - strongSwan now communicates with attached smartcards and | |
1480 | USB crypto tokens via the standardized PKCS #11 interface. | |
1481 | By default the OpenSC library from www.opensc.org is used | |
1482 | but any other PKCS#11 library could be dynamically linked. | |
1483 | strongSwan's PKCS#11 API was implemented by David Buechi | |
1484 | and Michael Meier, both graduates of the Zurich University | |
1485 | of Applied Sciences in Winterthur, Switzerland. | |
1486 | ||
1487 | - When a %trap eroute is triggered by an outgoing IP packet | |
1488 | then the native IPsec stack of the Linux 2.6 kernel [often/ | |
1489 | always?] returns an XFRM_ACQUIRE message with an undefined | |
1490 | protocol family field and the connection setup fails. | |
1491 | As a workaround IPv4 (AF_INET) is now assumed. | |
b6b90b68 MW |
1492 | |
1493 | - the results of the UML test scenarios are now enhanced | |
997358a6 | 1494 | with block diagrams of the virtual network topology used |
b6b90b68 | 1495 | in a particular test. |
997358a6 MW |
1496 | |
1497 | ||
1498 | strongswan-2.3.2 | |
1499 | ---------------- | |
1500 | ||
1501 | - fixed IV used to decrypt informational messages. | |
1502 | This bug was introduced with Mode Config functionality. | |
b6b90b68 | 1503 | |
997358a6 MW |
1504 | - fixed NCP Vendor ID. |
1505 | ||
1506 | - undid one of Ulrich Weber's maximum udp size patches | |
1507 | because it caused a segmentation fault with NAT-ed | |
1508 | Delete SA messages. | |
b6b90b68 | 1509 | |
997358a6 MW |
1510 | - added UML scenarios wildcards and attr-cert which |
1511 | demonstrate the implementation of IPsec policies based | |
1512 | on wildcard parameters contained in Distinguished Names and | |
1513 | on X.509 attribute certificates, respectively. | |
1514 | ||
1515 | ||
1516 | strongswan-2.3.1 | |
1517 | ---------------- | |
1518 | ||
1519 | - Added basic Mode Config functionality | |
1520 | ||
1521 | - Added Mathieu Lafon's patch which upgrades the status of | |
1522 | the NAT-Traversal implementation to RFC 3947. | |
b6b90b68 | 1523 | |
997358a6 MW |
1524 | - The _startklips script now also loads the xfrm4_tunnel |
1525 | module. | |
b6b90b68 | 1526 | |
997358a6 MW |
1527 | - Added Ulrich Weber's netlink replay window size and |
1528 | maximum udp size patches. | |
1529 | ||
1530 | - UML testing now uses the Linux 2.6.10 UML kernel by default. | |
b6b90b68 | 1531 | |
997358a6 MW |
1532 | |
1533 | strongswan-2.3.0 | |
1534 | ---------------- | |
1535 | ||
1536 | - Eric Marchionni and Patrik Rayo, both recent graduates from | |
1537 | the Zuercher Hochschule Winterthur in Switzerland, created a | |
1538 | User-Mode-Linux test setup for strongSwan. For more details | |
1539 | please read the INSTALL and README documents in the testing | |
1540 | subdirectory. | |
1541 | ||
1542 | - Full support of group attributes based on X.509 attribute | |
b6b90b68 | 1543 | certificates. Attribute certificates can be generated |
997358a6 | 1544 | using the openac facility. For more details see |
b6b90b68 | 1545 | |
997358a6 | 1546 | man ipsec_openac. |
b6b90b68 | 1547 | |
997358a6 MW |
1548 | The group attributes can be used in connection definitions |
1549 | in order to give IPsec access to specific user groups. | |
1550 | This is done with the new parameter left|rightgroups as in | |
b6b90b68 | 1551 | |
997358a6 MW |
1552 | rightgroups="Research, Sales" |
1553 | ||
1554 | giving access to users possessing the group attributes | |
1555 | Research or Sales, only. | |
1556 | ||
1557 | - In Quick Mode clients with subnet mask /32 are now | |
b6b90b68 | 1558 | coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should |
997358a6 MW |
1559 | fix rekeying problems with the SafeNet/SoftRemote and NCP |
1560 | Secure Entry Clients. | |
1561 | ||
1562 | - Changed the defaults of the ikelifetime and keylife parameters | |
1563 | to 3h and 1h, respectively. The maximum allowable values are | |
1564 | now both set to 24 h. | |
1565 | ||
1566 | - Suppressed notification wars between two IPsec peers that | |
1567 | could e.g. be triggered by incorrect ISAKMP encryption. | |
1568 | ||
1569 | - Public RSA keys can now have identical IDs if either the | |
1570 | issuing CA or the serial number is different. The serial | |
1571 | number of a certificate is now shown by the command | |
b6b90b68 | 1572 | |
997358a6 MW |
1573 | ipsec auto --listpubkeys |
1574 | ||
1575 | ||
1576 | strongswan-2.2.2 | |
1577 | ---------------- | |
1578 | ||
1579 | - Added Tuomo Soini's sourceip feature which allows a strongSwan | |
1580 | roadwarrior to use a fixed Virtual IP (see README section 2.6) | |
1581 | and reduces the well-known four tunnel case on VPN gateways to | |
1582 | a single tunnel definition (see README section 2.4). | |
1583 | ||
1584 | - Fixed a bug occuring with NAT-Traversal enabled when the responder | |
1585 | suddenly turns initiator and the initiator cannot find a matching | |
1586 | connection because of the floated IKE port 4500. | |
b6b90b68 | 1587 | |

1593 | ||
1594 | strongswan-2.2.1 | |
1595 | ---------------- | |
1596 | ||
1597 | - Introduced the ipsec auto --listalgs monitoring command which lists | |
1598 | all currently registered IKE and ESP algorithms. | |
1599 | ||
1600 | - Fixed a bug in the ESP algorithm selection occuring when the strict flag | |
1601 | is set and the first proposed transform does not match. | |
b6b90b68 | 1602 | |
997358a6 MW |
1603 | - Fixed another deadlock in the use of the lock_certs_and_keys() mutex, |
1604 | occuring when a smartcard is present. | |
1605 | ||
1606 | - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event. | |
b6b90b68 | 1607 | |
997358a6 MW |
1608 | - Fixed the printing of the notification names (null) |
1609 | ||
1610 | - Applied another of Herbert Xu's Netlink patches. | |
1611 | ||
1612 | ||
1613 | strongswan-2.2.0 | |
1614 | ---------------- | |
1615 | ||
1616 | - Support of Dead Peer Detection. The connection parameter | |
1617 | ||
1618 | dpdaction=clear|hold | |
b6b90b68 | 1619 | |
997358a6 MW |
1620 | activates DPD for the given connection. |
1621 | ||
1622 | - The default Opportunistic Encryption (OE) policy groups are not | |
1623 | automatically included anymore. Those wishing to activate OE can include | |
1624 | the policy group with the following statement in ipsec.conf: | |
b6b90b68 | 1625 | |
997358a6 | 1626 | include /etc/ipsec.d/examples/oe.conf |
b6b90b68 | 1627 | |
997358a6 MW |
1628 | The default for [right|left]rsasigkey is now set to %cert. |
1629 | ||
1630 | - strongSwan now has a Vendor ID of its own which can be activated | |
1631 | using the compile option VENDORID | |
1632 | ||
1633 | - Applied Herbert Xu's patch which sets the compression algorithm correctly. | |
1634 | ||
1635 | - Applied Herbert Xu's patch fixing an ESPINUDP problem | |

1648 | strongswan-2.1.5 | |
1649 | ---------------- | |
1650 | ||
1651 | - Thomas Walpuski made me aware of a potential DoS attack via | |
1652 | a PKCS#7-wrapped certificate bundle which could overwrite valid CA | |
1653 | certificates in Pluto's authority certificate store. This vulnerability | |
1654 | was fixed by establishing trust in CA candidate certificates up to a | |
1655 | trusted root CA prior to insertion into Pluto's chained list. | |
1656 | ||
1657 | - replaced the --assign option by the -v option in the auto awk script | |
1658 | in order to make it run with mawk under debian/woody. | |
1659 | ||
1660 | ||
1661 | strongswan-2.1.4 | |
1662 | ---------------- | |
1663 | ||
1664 | - Split of the status information between ipsec auto --status (concise) | |
1665 | and ipsec auto --statusall (verbose). Both commands can be used with | |
1666 | an optional connection selector: | |
1667 | ||
1668 | ipsec auto --status[all] <connection_name> | |
1669 | ||
1670 | - Added the description of X.509 related features to the ipsec_auto(8) | |
1671 | man page. | |
1672 | ||
1673 | - Hardened the ASN.1 parser in debug mode, especially the printing | |
1674 | of malformed distinguished names. | |
1675 | ||
1676 | - The size of an RSA public key received in a certificate is now restricted to | |
1677 | ||
1678 | 512 bits <= modulus length <= 8192 bits. | |
1679 | ||
1680 | - Fixed the debug mode enumeration. | |
1681 | ||
1682 | ||
1683 | strongswan-2.1.3 | |
1684 | ---------------- | |
1685 | ||
1686 | - Fixed another PKCS#7 vulnerability which could lead to an | |
1687 | endless loop while following the X.509 trust chain. | |
b6b90b68 | 1688 | |
997358a6 MW |
1689 | |
1690 | strongswan-2.1.2 | |
1691 | ---------------- | |
1692 | ||
1693 | - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski | |
1694 | that accepted end certificates having identical issuer and subject | |
1695 | distinguished names in a multi-tier X.509 trust chain. | |
b6b90b68 | 1696 | |
997358a6 MW |
1697 | |
1698 | strongswan-2.1.1 | |
1699 | ---------------- | |
1700 | ||
1701 | - Removed all remaining references to ipsec_netlink.h in KLIPS. | |
1702 | ||
1703 | ||
1704 | strongswan-2.1.0 | |
1705 | ---------------- | |
1706 | ||
1707 | - The new "ca" section allows to define the following parameters: | |
1708 | ||
1709 | ca kool | |
1710 | cacert=koolCA.pem # cacert of kool CA | |
1711 | ocspuri=http://ocsp.kool.net:8001 # ocsp server | |
1712 | ldapserver=ldap.kool.net # default ldap server | |
1713 | crluri=http://www.kool.net/kool.crl # crl distribution point | |
1714 | crluri2="ldap:///O=Kool, C= .." # crl distribution point #2 | |
1715 | auto=add # add, ignore | |
b6b90b68 | 1716 | |
997358a6 | 1717 | The ca definitions can be monitored via the command |
b6b90b68 | 1718 | |
997358a6 MW |
1719 | ipsec auto --listcainfos |
1720 | ||
1721 | - Fixed cosmetic corruption of /proc filesystem by integrating | |
1722 | D. Hugh Redelmeier's freeswan-2.06 kernel fixes. | |
1723 | ||
1724 | ||
1725 | strongswan-2.0.2 | |
1726 | ---------------- | |
1727 | ||
1728 | - Added support for the 818043 NAT-Traversal update of Microsoft's | |
1729 | Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode. | |
b6b90b68 MW |
1730 | |
1731 | - A symbolic link to libcrypto is now added in the kernel sources | |
997358a6 | 1732 | during kernel compilation |
b6b90b68 | 1733 | |
997358a6 MW |
1734 | - Fixed a couple of 64 bit issues (mostly casts to int). |
1735 | Thanks to Ken Bantoft who checked my sources on a 64 bit platform. | |
1736 | ||
1737 | - Replaced s[n]printf() statements in the kernel by ipsec_snprintf(). | |
1738 | Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro | |
1739 | of the FreeS/WAN team who solved this problem with the 2.4.25 kernel. | |
1740 | ||
1741 | ||
1742 | strongswan-2.0.1 | |
1743 | ---------------- | |
1744 | ||
1745 | - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName | |
1746 | certificate extension which contains no generalName item) can cause | |
1747 | a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has | |
1748 | been hardened to make it more robust against malformed ASN.1 objects. | |
1749 | ||
1750 | - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native | |
1751 | Linux 2.6 IPsec stack. | |
