1 | strongswan-4.5.3 |
2 | ---------------- | |
3 | ||
a7edbd21 | 4 | - Our private libraries (e.g. libstrongswan) are not installed directly in |
b18a697a AS |
5 | prefix/lib anymore. Instead a subdirectory is used (prefix/lib/ipsec/ by |
6 | default). The plugins directory is also moved from libexec/ipsec/ to that | |
a7edbd21 TB |
7 | directory. |
8 | ||
b18a697a AS |
9 | - The dynamic IMC/IMV libraries were moved from the plugins directory to |
10 | a new imcvs directory in the prefix/lib/ipsec/ subdirectory. | |
11 | ||
f8799170 | 12 | - IKEv2 charon daemon supports start PASS and DROP shunt policies |
b18a697a AS |
13 | preventing traffic to go through IPsec connections. Installation of the |
14 | shunt policies either via the XFRM netfilter or PFKEYv2 IPsec kernel interfaces. | |
f8799170 | 15 | |
93095183 TB |
16 | - The history of policies installed in the kernel is now tracked so that e.g. |
17 | trap policies are correctly updated when reauthenticated SAs are terminated. | |
18 | ||
b18a697a AS |
19 | - IMC/IMV Scanner pair implementing the RFC 5792 PA-TNC (IF-M) protocol. |
20 | Using "netstat -l" the IMC scans open listening ports on the TNC client | |
21 | and sends a port list to the IMV which based on a port policy decides if | |
22 | the client is admitted to the network. | |
23 | (--enable-imc-scanner/--enable-imv-scanner). | |
24 | ||
25 | - IMC/IMV Test pair implementing the RFC 5792 PA-TNC (IF-M) protocol. | |
5d179d19 AS |
26 | (--enable-imc-test/--enable-imv-test). |
27 | ||
4876f896 MW |
28 | - The IKEv2 close action does not use the same value as the ipsec.conf dpdaction |
29 | setting, but the value defined by its own closeaction keyword. The action | |
30 | is triggered if the remote peer closes a CHILD_SA unexpectedly. | |
5d179d19 | 31 | |
6f2378c1 AS |
32 | strongswan-4.5.2 |
33 | ---------------- | |
34 | ||
320e98c2 MW |
35 | - The whitelist plugin for the IKEv2 daemon maintains an in-memory identity |
36 | whitelist. Any connection attempt of peers not whitelisted will get rejected. | |
37 | The 'ipsec whitelist' utility provides a simple command line frontend for | |
38 | whitelist administration. | |
39 | ||
92ebb7c5 | 40 | - The duplicheck plugin provides a specialized form of duplicate checking, |
5832d505 | 41 | doing a liveness check on the old SA and optionally notify a third party |
92ebb7c5 MW |
42 | application about detected duplicates. |
43 | ||
44 | - The coupling plugin permanently couples two or more devices by limiting | |
45 | authentication to previously used certificates. | |
46 | ||
6f2378c1 AS |
47 | - In the case that the peer config and child config don't have the same name |
48 | (usually in SQL database defined connections), ipsec up|route <peer config> | |
49 | starts|routes all associated child configs and ipsec up|route <child config> | |
50 | only starts|routes the specific child config. | |
51 | ||
6ca05fe2 AS |
52 | - fixed the encoding and parsing of X.509 certificate policy statements (CPS). |
53 | ||
1ee7440b AS |
54 | - Duncan Salerno contributed the eap-sim-pcsc plugin implementing a |
55 | pcsc-lite based SIM card backend. | |
56 | ||
57 | - The eap-peap plugin implements the EAP PEAP protocol. Interoperates | |
2778b664 | 58 | successfully with a FreeRADIUS server and Windows 7 Agile VPN clients. |
1ee7440b | 59 | |
cf6ca6d7 MW |
60 | - The IKEv2 daemon charon rereads strongswan.conf on SIGHUP and instructs |
61 | all plugins to reload. Currently only the eap-radius and the attr plugins | |
62 | support configuration reloading. | |
63 | ||
d3d21c29 MW |
64 | - Added userland support to the IKEv2 daemon for Extended Sequence Numbers |
65 | support coming with Linux 2.6.39. To enable ESN on a connection, add | |
66 | the 'esn' keyword to the proposal. The default proposal uses 32-bit sequence | |
67 | numbers only ('noesn'), and the same value is used if no ESN mode is | |
68 | specified. To negotiate ESN support with the peer, include both, e.g. | |
69 | esp=aes128-sha1-esn-noesn. | |
70 | ||
71 | - In addition to ESN, Linux 2.6.39 gained support for replay windows larger | |
72 | than 32 packets. The new global strongswan.conf option 'charon.replay_window' | |
73 | configures the size of the replay window, in packets. | |
74 | ||

76 | strongswan-4.5.1 |
77 | ---------------- | |
78 | ||
1b7e081b AS |
79 | - Sansar Choinyambuu implemented the RFC 5793 Posture Broker Protocol (BP) |
80 | compatible with Trusted Network Connect (TNC). The TNCCS 2.0 protocol | |
5cdaafef | 81 | requires the tnccs_20, tnc_imc and tnc_imv plugins but does not depend |
1b7e081b AS |
82 | on the libtnc library. Any available IMV/IMC pairs conforming to the |
83 | Trusted Computing Group's TNC-IF-IMV/IMC 1.2 interface specification | |
e44817df | 84 | can be loaded via /etc/tnc_config. |
1b7e081b | 85 | |
5cdaafef AS |
86 | - Re-implemented the TNCCS 1.1 protocol by using the tnc_imc and tnc_imv |
87 | in place of the external libtnc library. | |
88 | ||
89 | - The tnccs_dynamic plugin loaded on a TNC server in addition to the | |
90 | tnccs_11 and tnccs_20 plugins, dynamically detects the IF-TNCCS | |
91 | protocol version used by a TNC client and invokes an instance of | |
92 | the corresponding protocol stack. | |
93 | ||
41ba5ce7 AS |
94 | - IKE and ESP proposals can now be stored in an SQL database using a |
95 | new proposals table. The start_action field in the child_configs | |
96 | tables allows the automatic starting or routing of connections stored | |
97 | in an SQL database. | |
98 | ||
1b7e081b AS |
99 | - The new certificate_authorities and certificate_distribution_points |
100 | tables make it possible to store CRL and OCSP Certificate Distribution | |
101 | points in an SQL database. | |
102 | ||
ae09bc62 TB |
103 | - The new 'include' statement allows to recursively include other files in |
104 | strongswan.conf. Existing sections and values are thereby extended and | |
105 | replaced, respectively. | |
106 | ||
107 | - Due to the changes in the parser for strongswan.conf, the configuration | |
108 | syntax for the attr plugin has changed. Previously, it was possible to | |
109 | specify multiple values of a specific attribute type by adding multiple | |
110 | key/value pairs with the same key (e.g. dns) to the plugins.attr section. | |
111 | Because values with the same key now replace previously defined values | |
112 | this is not possible anymore. As an alternative, multiple values can be | |
113 | specified by separating them with a comma (e.g. dns = 1.2.3.4, 2.3.4.5). | |
114 | ||
840e7044 AS |
115 | - ipsec listalgs now appends (set in square brackets) to each crypto |
116 | algorithm listed the plugin that registered the function. | |
117 | ||
e44817df MW |
118 | - Traffic Flow Confidentiality padding supported with Linux 2.6.38 can be used |
119 | by the IKEv2 daemon. The ipsec.conf 'tfc' keyword pads all packets to a given | |
120 | boundary, the special value '%mtu' pads all packets to the path MTU. | |
121 | ||
78a547c9 MW |
122 | - The new af-alg plugin can use various crypto primitives of the Linux Crypto |
123 | API using the AF_ALG interface introduced with 2.6.38. This removes the need | |
124 | for additional userland implementations of symmetric cipher, hash, hmac and | |
125 | xcbc algorithms. | |
44582075 | 126 | |
41ed0294 | 127 | - The IKEv2 daemon supports the INITIAL_CONTACT notify as initiator and |
983a5e88 MW |
128 | responder. The notify is sent when initiating configurations with a unique |
129 | policy, set in ipsec.conf via the global 'uniqueids' option. | |
41ed0294 | 130 | |
f0783464 MW |
131 | - The conftest conformance testing framework enables the IKEv2 stack to perform |
132 | many tests using a distinct tool and configuration frontend. Various hooks | |
133 | can alter reserved bits, flags, add custom notifies and proposals, reorder | |
134 | or drop messages and much more. It is enabled using the --enable-conftest | |
135 | ./configure switch. | |
136 | ||
77eee25f MW |
137 | - The new libstrongswan constraints plugin provides advanced X.509 constraint |
138 | checking. In additon to X.509 pathLen constraints, the plugin checks for | |
139 | nameConstraints and certificatePolicies, including policyMappings and | |
140 | policyConstraints. The x509 certificate plugin and the pki tool have been | |
96c4addc MW |
141 | enhanced to support these extensions. The new left/rightcertpolicy ipsec.conf |
142 | connection keywords take OIDs a peer certificate must have. | |
143 | ||
144 | - The left/rightauth ipsec.conf keywords accept values with a minimum strength | |
145 | for trustchain public keys in bits, such as rsa-2048 or ecdsa-256. | |
77eee25f | 146 | |
fb1e7df1 MW |
147 | - The revocation and x509 libstrongswan plugins and the pki tool gained basic |
148 | support for delta CRLs. | |
149 | ||
5cdaafef | 150 | |

151 | strongswan-4.5.0 |
152 | ---------------- | |
153 | ||
b14923ec AS |
154 | - IMPORTANT: the default keyexchange mode 'ike' is changing with release 4.5 |
155 | from 'ikev1' to 'ikev2', thus commemorating the five year anniversary of the | |
ac544be2 | 156 | IKEv2 RFC 4306 and its mature successor RFC 5996. The time has definitively |
b14923ec | 157 | come for IKEv1 to go into retirement and to cede its place to the much more |
ac544be2 | 158 | robust, powerful and versatile IKEv2 protocol! |
b14923ec | 159 | |
44582075 MW |
160 | - Added new ctr, ccm and gcm plugins providing Counter, Counter with CBC-MAC |
161 | and Galois/Counter Modes based on existing CBC implementations. These | |
162 | new plugins bring support for AES and Camellia Counter and CCM algorithms | |
163 | and the AES GCM algorithms for use in IKEv2. | |
164 | ||
84c9bc42 MW |
165 | - The new pkcs11 plugin brings full Smartcard support to the IKEv2 daemon and |
166 | the pki utility using one or more PKCS#11 libraries. It currently supports | |
61df42cc | 167 | RSA private and public key operations and loads X.509 certificates from |
84c9bc42 MW |
168 | tokens. |
169 | ||
a782b52f MW |
170 | - Implemented a general purpose TLS stack based on crypto and credential |
171 | primitives of libstrongswan. libtls supports TLS versions 1.0, 1.1 and 1.2, | |
172 | ECDHE-ECDSA/RSA, DHE-RSA and RSA key exchange algorithms and RSA/ECDSA based | |
173 | client authentication. | |
174 | ||
175 | - Based on libtls, the eap-tls plugin brings certificate based EAP | |
176 | authentication for client and server. It is compatible to Windows 7 IKEv2 | |
61df42cc | 177 | Smartcard authentication and the OpenSSL based FreeRADIUS EAP-TLS backend. |
a782b52f | 178 | |
8a1353fc AS |
179 | - Implemented the TNCCS 1.1 Trusted Network Connect protocol using the |
180 | libtnc library on the strongSwan client and server side via the tnccs_11 | |
181 | plugin and optionally connecting to a TNC@FHH-enhanced FreeRADIUS AAA server. | |
182 | Depending on the resulting TNC Recommendation, strongSwan clients are granted | |
183 | access to a network behind a strongSwan gateway (allow), are put into a | |
ac544be2 | 184 | remediation zone (isolate) or are blocked (none), respectively. Any number |
8a1353fc AS |
185 | of Integrity Measurement Collector/Verifier pairs can be attached |
186 | via the tnc-imc and tnc-imv charon plugins. | |
187 | ||
b3cabd1f TB |
188 | - The IKEv1 daemon pluto now uses the same kernel interfaces as the IKEv2 |
189 | daemon charon. As a result of this, pluto now supports xfrm marks which | |
190 | were introduced in charon with 4.4.1. | |
191 | ||
192 | - Applets for Maemo 5 (Nokia) allow to easily configure and control IKEv2 | |
193 | based VPN connections with EAP authentication on supported devices. | |
194 | ||
18a4f865 MW |
195 | - The RADIUS plugin eap-radius now supports multiple RADIUS servers for |
196 | redundant setups. Servers are selected by a defined priority, server load and | |
197 | availability. | |
198 | ||
199 | - The simple led plugin controls hardware LEDs through the Linux LED subsystem. | |
200 | It currently shows activity of the IKE daemon and is a good example how to | |
201 | implement a simple event listener. | |
202 | ||
b3cabd1f TB |
203 | - Improved MOBIKE behavior in several corner cases, for instance, if the |
204 | initial responder moves to a different address. | |
205 | ||
206 | - Fixed left-/rightnexthop option, which was broken since 4.4.0. | |
207 | ||
3f84e2d6 AS |
208 | - Fixed a bug not releasing a virtual IP address to a pool if the XAUTH |
209 | identity was different from the IKE identity. | |
210 | ||
f6032361 AS |
211 | - Fixed the alignment of ModeConfig messages on 4-byte boundaries in the |
212 | case where the attributes are not a multiple of 4 bytes (e.g. Cisco's | |
213 | UNITY_BANNER). | |
214 | ||
215 | - Fixed the interoperability of the socket_raw and socket_default | |
216 | charon plugins. | |
217 | ||
3f84e2d6 AS |
218 | - Added man page for strongswan.conf |
219 | ||
a782b52f | 220 | |
03b5e4d8 AS |
221 | strongswan-4.4.1 |
222 | ---------------- | |
223 | ||
ec40c02a | 224 | - Support of xfrm marks in IPsec SAs and IPsec policies introduced |
b22bb9f2 AS |
225 | with the Linux 2.6.34 kernel. For details see the example scenarios |
226 | ikev2/nat-two-rw-mark, ikev2/rw-nat-mark-in-out and ikev2/net2net-psk-dscp. | |
ec40c02a | 227 | |
b22bb9f2 | 228 | - The PLUTO_MARK_IN and PLUTO_ESP_ENC environment variables can be used |
b59340a2 AS |
229 | in a user-specific updown script to set marks on inbound ESP or |
230 | ESP_IN_UDP packets. | |
e87b78c6 | 231 | |
3561cc4b AS |
232 | - The openssl plugin now supports X.509 certificate and CRL functions. |
233 | ||
e9448cfc | 234 | - OCSP/CRL checking in IKEv2 has been moved to the revocation plugin, enabled |
b59340a2 | 235 | by default. Plase update manual load directives in strongswan.conf. |
e9448cfc MW |
236 | |
237 | - RFC3779 ipAddrBlock constraint checking has been moved to the addrblock | |
238 | plugin, disabled by default. Enable it and update manual load directives | |
239 | in strongswan.conf, if required. | |
240 | ||
7f3a9468 MW |
241 | - The pki utility supports CRL generation using the --signcrl command. |
242 | ||
243 | - The ipsec pki --self, --issue and --req commands now support output in | |
244 | PEM format using the --outform pem option. | |
245 | ||
03b5e4d8 AS |
246 | - The major refactoring of the IKEv1 Mode Config functionality now allows |
247 | the transport and handling of any Mode Config attribute. | |
248 | ||
e87b78c6 | 249 | - The RADIUS proxy plugin eap-radius now supports multiple servers. Configured |
b59340a2 AS |
250 | servers are chosen randomly, with the option to prefer a specific server. |
251 | Non-responding servers are degraded by the selection process. | |
e87b78c6 | 252 | |
c5c6f9b6 AS |
253 | - The ipsec pool tool manages arbitrary configuration attributes stored |
254 | in an SQL database. ipsec pool --help gives the details. | |
255 | ||
fe2434cf MW |
256 | - The new eap-simaka-sql plugin acts as a backend for EAP-SIM and EAP-AKA, |
257 | reading triplets/quintuplets from an SQL database. | |
258 | ||
c8bd06c7 MW |
259 | - The High Availability plugin now supports a HA enabled in-memory address |
260 | pool and Node reintegration without IKE_SA rekeying. The latter allows | |
261 | clients without IKE_SA rekeying support to keep connected during | |
262 | reintegration. Additionally, many other issues have been fixed in the ha | |
263 | plugin. | |
1c1f132a | 264 | |
c5c921bf MW |
265 | - Fixed a potential remote code execution vulnerability resulting from |
266 | the misuse of snprintf(). The vulnerability is exploitable by | |
267 | unauthenticated users. | |
268 | ||
03b5e4d8 | 269 | |
00c60592 MW |
270 | strongswan-4.4.0 |
271 | ---------------- | |
272 | ||
d101a61f MW |
273 | - The IKEv2 High Availability plugin has been integrated. It provides |
274 | load sharing and failover capabilities in a cluster of currently two nodes, | |
275 | based on an extend ClusterIP kernel module. More information is available at | |
276 | http://wiki.strongswan.org/projects/strongswan/wiki/HighAvailability. | |
9235edc2 | 277 | The development of the High Availability functionality was sponsored by |
d101a61f MW |
278 | secunet Security Networks AG. |
279 | ||
dd8cb2b0 AS |
280 | - Added IKEv1 and IKEv2 configuration support for the AES-GMAC |
281 | authentication-only ESP cipher. Our aes_gmac kernel patch or a Linux | |
282 | 2.6.34 kernel is required to make AES-GMAC available via the XFRM | |
283 | kernel interface. | |
284 | ||
4590260b MW |
285 | - Added support for Diffie-Hellman groups 22, 23 and 24 to the gmp, gcrypt |
286 | and openssl plugins, usable by both pluto and charon. The new proposal | |
287 | keywords are modp1024s160, modp2048s224 and modp2048s256. Thanks to Joy Latten | |
288 | from IBM for his contribution. | |
289 | ||
9235edc2 AS |
290 | - The IKEv1 pluto daemon supports RAM-based virtual IP pools using |
291 | the rightsourceip directive with a subnet from which addresses | |
292 | are allocated. | |
293 | ||
d6457833 AS |
294 | - The ipsec pki --gen and --pub commands now allow the output of |
295 | private and public keys in PEM format using the --outform pem | |
296 | command line option. | |
297 | ||
2d097a0b MW |
298 | - The new DHCP plugin queries virtual IP addresses for clients from a DHCP |
299 | server using broadcasts, or a defined server using the | |
300 | charon.plugins.dhcp.server strongswan.conf option. DNS/WINS server information | |
301 | is additionally served to clients if the DHCP server provides such | |
302 | information. The plugin is used in ipsec.conf configurations having | |
303 | rightsourceip set to %dhcp. | |
304 | ||
6d6994c6 MW |
305 | - A new plugin called farp fakes ARP responses for virtual IP addresses |
306 | handed out to clients from the IKEv2 daemon charon. The plugin lets a | |
89bf11d2 | 307 | road-warrior act as a client on the local LAN if it uses a virtual IP |
6d6994c6 MW |
308 | from the responders subnet, e.g. acquired using the DHCP plugin. |
309 | ||
00c60592 MW |
310 | - The existing IKEv2 socket implementations have been migrated to the |
311 | socket-default and the socket-raw plugins. The new socket-dynamic plugin | |
312 | binds sockets dynamically to ports configured via the left-/rightikeport | |
313 | ipsec.conf connection parameters. | |
314 | ||
3e6b50ed MW |
315 | - The android charon plugin stores received DNS server information as "net.dns" |
316 | system properties, as used by the Android platform. | |
00c60592 | 317 | |
d6457833 | 318 | |
4c68a85a AS |
319 | strongswan-4.3.6 |
320 | ---------------- | |
321 | ||
cdad91de | 322 | - The IKEv2 daemon supports RFC 3779 IP address block constraints |
e98a4d80 AS |
323 | carried as a critical X.509v3 extension in the peer certificate. |
324 | ||
a7155606 AS |
325 | - The ipsec pool --add|del dns|nbns command manages DNS and NBNS name |
326 | server entries that are sent via the IKEv1 Mode Config or IKEv2 | |
327 | Configuration Payload to remote clients. | |
328 | ||
f721e0fb AS |
329 | - The Camellia cipher can be used as an IKEv1 encryption algorithm. |
330 | ||
4c68a85a AS |
331 | - The IKEv1 and IKEV2 daemons now check certificate path length constraints. |
332 | ||
909c0c3d MW |
333 | - The new ipsec.conf conn option "inactivity" closes a CHILD_SA if no traffic |
334 | was sent or received within the given interval. To close the complete IKE_SA | |
335 | if its only CHILD_SA was inactive, set the global strongswan.conf option | |
aa9eeb5d MW |
336 | "charon.inactivity_close_ike" to yes. |
337 | ||
44e41c4c AS |
338 | - More detailed IKEv2 EAP payload information in debug output |
339 | ||
2b2c69e9 | 340 | - IKEv2 EAP-SIM and EAP-AKA share joint libsimaka library |
44e41c4c | 341 | |
52fd0ef9 MW |
342 | - Added required userland changes for proper SHA256 and SHA384/512 in ESP that |
343 | will be introduced with Linux 2.6.33. The "sha256"/"sha2_256" keyword now | |
344 | configures the kernel with 128 bit truncation, not the non-standard 96 | |
345 | bit truncation used by previous releases. To use the old 96 bit truncation | |
346 | scheme, the new "sha256_96" proposal keyword has been introduced. | |
4c68a85a | 347 | |
2b2c69e9 MW |
348 | - Fixed IPComp in tunnel mode, stripping out the duplicated outer header. This |
349 | change makes IPcomp tunnel mode connections incompatible with previous | |
350 | releases; disable compression on such tunnels. | |
351 | ||
6ec949e0 MW |
352 | - Fixed BEET mode connections on recent kernels by installing SAs with |
353 | appropriate traffic selectors, based on a patch by Michael Rossberg. | |
354 | ||
cdad91de MW |
355 | - Using extensions (such as BEET mode) and crypto algorithms (such as twofish, |
356 | serpent, sha256_96) allocated in the private use space now require that we | |
357 | know its meaning, i.e. we are talking to strongSwan. Use the new | |
358 | "charon.send_vendor_id" option in strongswan.conf to let the remote peer know | |
359 | this is the case. | |

361 | - Experimental support for draft-eronen-ipsec-ikev2-eap-auth, where the |
362 | responder omits public key authentication in favor of a mutual authentication | |
363 | method. To enable EAP-only authentication, set rightauth=eap on the responder | |
364 | to rely only on the MSK constructed AUTH payload. This not-yet standardized | |
365 | extension requires the strongSwan vendor ID introduced above. | |
366 | ||
0a975307 AS |
367 | - The IKEv1 daemon ignores the Juniper SRX notification type 40001, thus |
368 | allowing interoperability. | |
369 | ||
370 | ||

371 | strongswan-4.3.5 |
372 | ---------------- | |
373 | ||
628f023d AS |
374 | - The IKEv1 pluto daemon can now use SQL-based address pools to deal out |
375 | virtual IP addresses as a Mode Config server. The pool capability has been | |
376 | migrated from charon's sql plugin to a new attr-sql plugin which is loaded | |
b42bfc79 | 377 | by libstrongswan and which can be used by both daemons either with a SQLite |
628f023d AS |
378 | or MySQL database and the corresponding plugin. |
379 | ||
b42bfc79 MW |
380 | - Plugin names have been streamlined: EAP plugins now have a dash after eap |
381 | (e.g. eap-sim), as it is used with the --enable-eap-sim ./configure option. | |
382 | Plugin configuration sections in strongswan.conf now use the same name as the | |
383 | plugin itself (i.e. with a dash). Make sure to update "load" directives and | |
384 | the affected plugin sections in existing strongswan.conf files. | |
385 | ||
d245f5cf AS |
386 | - The private/public key parsing and encoding has been split up into |
387 | separate pkcs1, pgp, pem and dnskey plugins. The public key implementation | |
388 | plugins gmp, gcrypt and openssl can all make use of them. | |
b6b90b68 | 389 | |
55b045ab MW |
390 | - The EAP-AKA plugin can use different backends for USIM/quintuplet |
391 | calculations, very similar to the EAP-SIM plugin. The existing 3GPP2 software | |
392 | implementation has been migrated to a separate plugin. | |
393 | ||
d245f5cf | 394 | - The IKEv2 daemon charon gained basic PGP support. It can use locally installed |
b6b90b68 MW |
395 | peer certificates and can issue signatures based on RSA private keys. |
396 | ||
397 | - The new 'ipsec pki' tool provides a set of commands to maintain a public | |
398 | key infrastructure. It currently supports operations to create RSA and ECDSA | |
399 | private/public keys, calculate fingerprints and issue or verify certificates. | |
400 | ||
401 | - Charon uses a monotonic time source for statistics and job queueing, behaving | |
402 | correctly if the system time changes (e.g. when using NTP). | |
403 | ||
404 | - In addition to time based rekeying, charon supports IPsec SA lifetimes based | |
405 | on processed volume or number of packets. They new ipsec.conf paramaters | |
406 | 'lifetime' (an alias to 'keylife'), 'lifebytes' and 'lifepackets' handle | |
407 | SA timeouts, while the parameters 'margintime' (an alias to rekeymargin), | |
408 | 'marginbytes' and 'marginpackets' trigger the rekeying before a SA expires. | |
409 | The existing parameter 'rekeyfuzz' affects all margins. | |
410 | ||
85af7a89 MW |
411 | - If no CA/Gateway certificate is specified in the NetworkManager plugin, |
412 | charon uses a set of trusted root certificates preinstalled by distributions. | |
413 | The directory containing CA certificates can be specified using the | |
414 | --with-nm-ca-dir=path configure option. | |
415 | ||
b80fa9ca | 416 | - Fixed the encoding of the Email relative distinguished name in left|rightid |
509f70c1 | 417 | statements. |
b80fa9ca | 418 | |
509f70c1 AS |
419 | - Fixed the broken parsing of PKCS#7 wrapped certificates by the pluto daemon. |
420 | ||
421 | - Fixed smartcard-based authentication in the pluto daemon which was broken by | |
422 | the ECDSA support introduced with the 4.3.2 release. | |
423 | ||
cea4bd8f AS |
424 | - A patch contributed by Heiko Hund fixes mixed IPv6 in IPv4 and vice versa |
425 | tunnels established with the IKEv1 pluto daemon. | |
426 | ||
509f70c1 AS |
427 | - The pluto daemon now uses the libstrongswan x509 plugin for certificates and |
428 | CRls and the struct id type was replaced by identification_t used by charon | |
429 | and the libstrongswan library. | |
18060241 | 430 | |

430dd08a AS |
432 | strongswan-4.3.4 |
433 | ---------------- | |
434 | ||
435 | - IKEv2 charon daemon ported to FreeBSD and Mac OS X. Installation details can | |
436 | be found on wiki.strongswan.org. | |
437 | ||
438 | - ipsec statusall shows the number of bytes transmitted and received over | |
439 | ESP connections configured by the IKEv2 charon daemon. | |
440 | ||
441 | - The IKEv2 charon daemon supports include files in ipsec.secrets. | |
442 | ||

1c7f456a AS |
444 | strongswan-4.3.3 |
445 | ---------------- | |
446 | ||
aa74d705 AS |
447 | - The configuration option --enable-integrity-test plus the strongswan.conf |
448 | option libstrongswan.integrity_test = yes activate integrity tests | |
449 | of the IKE daemons charon and pluto, libstrongswan and all loaded | |
450 | plugins. Thus dynamic library misconfigurations and non-malicious file | |
451 | manipulations can be reliably detected. | |
452 | ||
1c7f456a AS |
453 | - The new default setting libstrongswan.ecp_x_coordinate_only=yes allows |
454 | IKEv1 interoperability with MS Windows using the ECP DH groups 19 and 20. | |
455 | ||
456 | - The IKEv1 pluto daemon now supports the AES-CCM and AES-GCM ESP | |
457 | authenticated encryption algorithms. | |
458 | ||
aa74d705 AS |
459 | - The IKEv1 pluto daemon now supports V4 OpenPGP keys. |
460 | ||
461 | - The RDN parser vulnerability discovered by Orange Labs research team | |
462 | was not completely fixed in version 4.3.2. Some more modifications | |
463 | had to be applied to the asn1_length() function to make it robust. | |
464 | ||
1c7f456a | 465 | |
80c0710c MW |
466 | strongswan-4.3.2 |
467 | ---------------- | |
468 | ||
469 | - The new gcrypt plugin provides symmetric cipher, hasher, RNG, Diffie-Hellman | |
470 | and RSA crypto primitives using the LGPL licensed GNU gcrypt library. | |
471 | ||
472 | - libstrongswan features an integrated crypto selftest framework for registered | |
473 | algorithms. The test-vector plugin provides a first set of test vectors and | |
474 | allows pluto and charon to rely on tested crypto algorithms. | |
475 | ||
b32af120 AS |
476 | - pluto can now use all libstrongswan plugins with the exception of x509 and xcbc. |
477 | Thanks to the openssl plugin, the ECP Diffie-Hellman groups 19, 20, 21, 25, and | |
478 | 26 as well as ECDSA-256, ECDSA-384, and ECDSA-521 authentication can be used | |
479 | with IKEv1. | |
126f2130 AS |
480 | |
481 | - Applying their fuzzing tool, the Orange Labs vulnerability research team found | |
482 | another two DoS vulnerabilities, one in the rather old ASN.1 parser of Relative | |
483 | Distinguished Names (RDNs) and a second one in the conversion of ASN.1 UTCTIME | |
484 | and GENERALIZEDTIME strings to a time_t value. | |

3bf7c249 MW |
487 | strongswan-4.3.1 |
488 | ---------------- | |
489 | ||
490 | - The nm plugin now passes DNS/NBNS server information to NetworkManager, | |
09dbca9f | 491 | allowing a gateway administrator to set DNS/NBNS configuration on clients |
3bf7c249 MW |
492 | dynamically. |
493 | ||
09dbca9f MW |
494 | - The nm plugin also accepts CA certificates for gateway authentication. If |
495 | a CA certificate is configured, strongSwan uses the entered gateway address | |
496 | as its idenitity, requiring the gateways certificate to contain the same as | |
497 | subjectAltName. This allows a gateway administrator to deploy the same | |
498 | certificates to Windows 7 and NetworkManager clients. | |
047b2e42 | 499 | |
050cc582 AS |
500 | - The command ipsec purgeike deletes IKEv2 SAs that don't have a CHILD SA. |
501 | The command ipsec down <conn>{n} deletes CHILD SA instance n of connection | |
502 | <conn> whereas ipsec down <conn>{*} deletes all CHILD SA instances. | |
503 | The command ipsec down <conn>[n] deletes IKE SA instance n of connection | |
504 | <conn> plus dependent CHILD SAs whereas ipsec down <conn>[*] deletes all | |
505 | IKE SA instances of connection <conn>. | |
506 | ||
09dbca9f | 507 | - Fixed a regression introduced in 4.3.0 where EAP authentication calculated |
047b2e42 MW |
508 | the AUTH payload incorrectly. Further, the EAP-MSCHAPv2 MSK key derivation |
509 | has been updated to be compatible with the Windows 7 Release Candidate. | |
510 | ||
511 | - Refactored installation of triggering policies. Routed policies are handled | |
512 | outside of IKE_SAs to keep them installed in any case. A tunnel gets | |
513 | established only once, even if initiation is delayed due network outages. | |
514 | ||
050cc582 AS |
515 | - Improved the handling of multiple acquire signals triggered by the kernel. |
516 | ||
517 | - Fixed two DoS vulnerabilities in the charon daemon that were discovered by | |
518 | fuzzing techniques: 1) Sending a malformed IKE_SA_INIT request leaved an | |
519 | incomplete state which caused a null pointer dereference if a subsequent | |
520 | CREATE_CHILD_SA request was sent. 2) Sending an IKE_AUTH request with either | |
521 | a missing TSi or TSr payload caused a null pointer derefence because the | |
b6b90b68 | 522 | checks for TSi and TSr were interchanged. The IKEv2 fuzzer used was |
050cc582 AS |
523 | developped by the Orange Labs vulnerability research team. The tool was |
524 | initially written by Gabriel Campana and is now maintained by Laurent Butti. | |
525 | ||
047b2e42 MW |
526 | - Added support for AES counter mode in ESP in IKEv2 using the proposal |
527 | keywords aes128ctr, aes192ctr and aes256ctr. | |
528 | ||
d44fd821 | 529 | - Further progress in refactoring pluto: Use of the curl and ldap plugins |
050cc582 AS |
530 | for fetching crls and OCSP. Use of the random plugin to get keying material |
531 | from /dev/random or /dev/urandom. Use of the openssl plugin as an alternative | |
d44fd821 | 532 | to the aes, des, sha1, sha2, and md5 plugins. The blowfish, twofish, and |
050cc582 | 533 | serpent encryption plugins are now optional and are not enabled by default. |
d44fd821 AS |

247e665a AS |
536 | strongswan-4.3.0 |
537 | ---------------- | |
538 | ||
81fc8e5f MW |
539 | - Support for the IKEv2 Multiple Authentication Exchanges extension (RFC4739). |
540 | Initiators and responders can use several authentication rounds (e.g. RSA | |
541 | followed by EAP) to authenticate. The new ipsec.conf leftauth/rightauth and | |
542 | leftauth2/rightauth2 parameters define own authentication rounds or setup | |
543 | constraints for the remote peer. See the ipsec.conf man page for more detials. | |
544 | ||
545 | - If glibc printf hooks (register_printf_function) are not available, | |
546 | strongSwan can use the vstr string library to run on non-glibc systems. | |
547 | ||
558c89e7 AS |
548 | - The IKEv2 charon daemon can now configure the ESP CAMELLIA-CBC cipher |
549 | (esp=camellia128|192|256). | |
247e665a | 550 | |
558c89e7 AS |
551 | - Refactored the pluto and scepclient code to use basic functions (memory |
552 | allocation, leak detective, chunk handling, printf_hooks, strongswan.conf | |
553 | attributes, ASN.1 parser, etc.) from the libstrongswan library. | |
b752f873 | 554 | |
558c89e7 AS |
555 | - Up to two DNS and WINS servers to be sent via IKEv1 ModeConfig can be |
556 | configured in the pluto section of strongswan.conf. | |

559 | strongswan-4.2.14 |
560 | ----------------- | |
561 | ||
22180558 AS |
562 | - The new server-side EAP RADIUS plugin (--enable-eap-radius) |
563 | relays EAP messages to and from a RADIUS server. Succesfully | |
564 | tested with with a freeradius server using EAP-MD5 and EAP-SIM. | |
565 | ||
79b27294 AS |
566 | - A vulnerability in the Dead Peer Detection (RFC 3706) code was found by |
567 | Gerd v. Egidy <gerd.von.egidy@intra2net.com> of Intra2net AG affecting | |
568 | all Openswan and strongSwan releases. A malicious (or expired ISAKMP) | |
569 | R_U_THERE or R_U_THERE_ACK Dead Peer Detection packet can cause the | |
570 | pluto IKE daemon to crash and restart. No authentication or encryption | |
571 | is required to trigger this bug. One spoofed UDP packet can cause the | |
572 | pluto IKE daemon to restart and be unresponsive for a few seconds while | |
573 | restarting. This DPD null state vulnerability has been officially | |
574 | registered as CVE-2009-0790 and is fixed by this release. | |
575 | ||
22180558 AS |
576 | - ASN.1 to time_t conversion caused a time wrap-around for |
577 | dates after Jan 18 03:14:07 UTC 2038 on 32-bit platforms. | |
578 | As a workaround such dates are set to the maximum representable | |
579 | time, i.e. Jan 19 03:14:07 UTC 2038. | |
580 | ||
581 | - Distinguished Names containing wildcards (*) are not sent in the | |
b6b90b68 | 582 | IDr payload anymore. |
623bca40 AS |

584 | ||
076e7853 AS |
585 | strongswan-4.2.13 |
586 | ----------------- | |
587 | ||
588 | - Fixed a use-after-free bug in the DPD timeout section of the | |
589 | IKEv1 pluto daemon which sporadically caused a segfault. | |
590 | ||
591 | - Fixed a crash in the IKEv2 charon daemon occuring with | |
b6b90b68 | 592 | mixed RAM-based and SQL-based virtual IP address pools. |
076e7853 | 593 | |
f15483ef AS |
594 | - Fixed ASN.1 parsing of algorithmIdentifier objects where the |
595 | parameters field is optional. | |
596 | ||
03991bc1 MW |
597 | - Ported nm plugin to NetworkManager 7.1. |

076e7853 | 601 | ----------------- |
bfde75ee AS |
602 | |
603 | - Support of the EAP-MSCHAPv2 protocol enabled by the option | |
604 | --enable-eap-mschapv2. Requires the MD4 hash algorithm enabled | |
605 | either by --enable-md4 or --enable-openssl. | |
606 | ||
607 | - Assignment of up to two DNS and up to two WINS servers to peers via | |
b6b90b68 | 608 | the IKEv2 Configuration Payload (CP). The IPv4 or IPv6 nameserver |
bfde75ee AS |
609 | addresses are defined in strongswan.conf. |
610 | ||
611 | - The strongSwan applet for the Gnome NetworkManager is now built and | |
612 | distributed as a separate tarball under the name NetworkManager-strongswan. | |
613 | ||

616 | ----------------- | |
617 | ||
ae1ae574 AS |
618 | - Fixed ESP NULL encryption broken by the refactoring of keymat.c. |
619 | Also introduced proper initialization and disposal of keying material. | |
620 | ||
621 | - Fixed the missing listing of connection definitions in ipsec statusall | |
622 | broken by an unfortunate local variable overload. | |
0519ca90 AS |
623 | |
624 | ||
4856241c MW |
625 | strongswan-4.2.10 |
626 | ----------------- | |
627 | ||
628 | - Several performance improvements to handle thousands of tunnels with almost | |
629 | linear upscaling. All relevant data structures have been replaced by faster | |
630 | counterparts with better lookup times. | |
631 | ||
632 | - Better parallelization to run charon on multiple cores. Due to improved | |
633 | ressource locking and other optimizations the daemon can take full | |
634 | advantage of 16 or even more cores. | |
635 | ||
636 | - The load-tester plugin can use a NULL Diffie-Hellman group and simulate | |
637 | unique identities and certificates by signing peer certificates using a CA | |
638 | on the fly. | |
639 | ||
640 | - The redesigned stroke in-memory IP pool handles leases. The "ipsec leases" | |
641 | command queries assigned leases. | |
642 | ||
643 | - Added support for smartcards in charon by using the ENGINE API provided by | |
644 | OpenSSL, based on patches by Michael Roßberg. | |
645 | ||
646 | - The Padlock plugin supports the hardware RNG found on VIA CPUs to provide a | |
647 | reliable source of randomness. | |
648 | ||
73937bd8 MW |
649 | strongswan-4.2.9 |
650 | ---------------- | |
651 | ||
509e07c5 AS |
652 | - Flexible configuration of logging subsystem allowing to log to multiple |
653 | syslog facilities or to files using fine-grained log levels for each target. | |
73937bd8 MW |
654 | |
655 | - Load testing plugin to do stress testing of the IKEv2 daemon against self | |
656 | or another host. Found and fixed issues during tests in the multi-threaded | |
657 | use of the OpenSSL plugin. | |
658 | ||
659 | - Added profiling code to synchronization primitives to find bottlenecks if | |
7bdc931e | 660 | running on multiple cores. Found and fixed an issue where parts of the |
73937bd8 MW |
661 | Diffie-Hellman calculation acquired an exclusive lock. This greatly improves |
662 | parallelization to multiple cores. | |
663 | ||
509e07c5 AS |
664 | - updown script invocation has been separated into a plugin of its own to |
665 | further slim down the daemon core. | |
73937bd8 | 666 | |
509e07c5 | 667 | - Separated IKE_SA/CHILD_SA key derivation process into a closed system, |
7bdc931e | 668 | allowing future implementations to use a secured environment in e.g. kernel |
73937bd8 MW |
669 | memory or hardware. |
670 | ||
509e07c5 AS |
671 | - The kernel interface of charon has been modularized. XFRM NETLINK (default) |
672 | and PFKEY (--enable-kernel-pfkey) interface plugins for the native IPsec | |
673 | stack of the Linux 2.6 kernel as well as a PFKEY interface for the KLIPS | |
674 | IPsec stack (--enable-kernel-klips) are provided. | |
675 | ||
676 | - Basic Mobile IPv6 support has been introduced, securing Binding Update | |
677 | messages as well as tunneled traffic between Mobile Node and Home Agent. | |
678 | The installpolicy=no option allows peaceful cooperation with a dominant | |
679 | mip6d daemon and the new type=transport_proxy implements the special MIPv6 | |
680 | IPsec transport proxy mode where the IKEv2 daemon uses the Care-of-Address | |
681 | but the IPsec SA is set up for the Home Adress. | |
7bdc931e | 682 | |
4dc0dce8 AS |
683 | - Implemented migration of Mobile IPv6 connections using the KMADDRESS |
684 | field contained in XFRM_MSG_MIGRATE messages sent by the mip6d daemon | |
685 | via the Linux 2.6.28 (or appropriately patched) kernel. | |

e39b271b AS |
688 | strongswan-4.2.8 |
689 | ---------------- | |
690 | ||
5dadb16e | 691 | - IKEv2 charon daemon supports authentication based on raw public keys |
e39b271b AS |
692 | stored in the SQL database backend. The ipsec listpubkeys command |
693 | lists the available raw public keys via the stroke interface. | |
694 | ||
4f0241e6 MW |
695 | - Several MOBIKE improvements: Detect changes in NAT mappings in DPD exchanges, |
696 | handle events if kernel detects NAT mapping changes in UDP-encapsulated | |
697 | ESP packets (requires kernel patch), reuse old addesses in MOBIKE updates as | |
698 | long as possible and other fixes. | |
699 | ||
5dadb16e AS |
700 | - Fixed a bug in addr_in_subnet() which caused insertion of wrong source |
701 | routes for destination subnets having netwmasks not being a multiple of 8 bits. | |
702 | Thanks go to Wolfgang Steudel, TU Ilmenau for reporting this bug. | |

705 | strongswan-4.2.7 |
706 | ---------------- | |
707 | ||
b37cda82 AS |
708 | - Fixed a Denial-of-Service vulnerability where an IKE_SA_INIT message with |
709 | a KE payload containing zeroes only can cause a crash of the IKEv2 charon | |
710 | daemon due to a NULL pointer returned by the mpz_export() function of the | |
711 | GNU Multiprecision Library (GMP). Thanks go to Mu Dynamics Research Labs | |
b6b90b68 | 712 | for making us aware of this problem. |
b37cda82 | 713 | |
b6b90b68 | 714 | - The new agent plugin provides a private key implementation on top of an |
e376d75f MW |
715 | ssh-agent. |
716 | ||
717 | - The NetworkManager plugin has been extended to support certificate client | |
b1f47854 | 718 | authentication using RSA keys loaded from a file or using ssh-agent. |
e376d75f MW |
719 | |
720 | - Daemon capability dropping has been ported to libcap and must be enabled | |
721 | explicitly --with-capabilities=libcap. Future version will support the | |
722 | newer libcap2 library. | |
723 | ||
b37cda82 AS |
724 | - ipsec listalgs lists the IKEv2 cryptografic algorithms registered with the |
725 | charon keying daemon. | |

728 | strongswan-4.2.6 |
729 | ---------------- | |
730 | ||
609166f4 MW |
731 | - A NetworkManager plugin allows GUI-based configuration of road-warrior |
732 | clients in a simple way. It features X509 based gateway authentication | |
733 | and EAP client authentication, tunnel setup/teardown and storing passwords | |
734 | in the Gnome Keyring. | |
735 | ||
736 | - A new EAP-GTC plugin implements draft-sheffer-ikev2-gtc-00.txt and allows | |
737 | username/password authentication against any PAM service on the gateway. | |
b6b90b68 | 738 | The new EAP method interacts nicely with the NetworkManager plugin and allows |

739 | client authentication against e.g. LDAP. |
740 | ||
741 | - Improved support for the EAP-Identity method. The new ipsec.conf eap_identity | |
742 | parameter defines an additional identity to pass to the server in EAP | |
743 | authentication. | |
744 | ||
9f9d6ece AS |
745 | - The "ipsec statusall" command now lists CA restrictions, EAP |
746 | authentication types and EAP identities. | |
747 | ||
748 | - Fixed two multithreading deadlocks occurring when starting up | |
749 | several hundred tunnels concurrently. | |
750 | ||
751 | - Fixed the --enable-integrity-test configure option which | |
752 | computes a SHA-1 checksum over the libstrongswan library. | |
753 | ||
754 | ||
174216c7 AS |
755 | strongswan-4.2.5 |
756 | ---------------- | |
757 | ||
b6b90b68 | 758 | - Consistent logging of IKE and CHILD SAs at the audit (AUD) level. |
8124e491 AS |
759 | |
760 | - Improved the performance of the SQL-based virtual IP address pool | |
761 | by introducing an additional addresses table. The leases table | |
762 | storing only history information has become optional and can be | |
763 | disabled by setting charon.plugins.sql.lease_history = no in | |
764 | strongswan.conf. | |
765 | ||
eb0cc338 | 766 | - The XFRM_STATE_AF_UNSPEC flag added to xfrm.h allows IPv4-over-IPv6 |
de5f70e7 | 767 | and IPv6-over-IPv4 tunnels with the 2.6.26 and later Linux kernels. |
eb0cc338 | 768 | |
174216c7 AS |
769 | - management of different virtual IP pools for different |
770 | network interfaces have become possible. | |
771 | ||
b6b90b68 | 772 | - fixed a bug which prevented the assignment of more than 256 |
174216c7 AS |
773 | virtual IP addresses from a pool managed by an sql database. |
774 | ||
8124e491 AS |
775 | - fixed a bug which did not delete own IPCOMP SAs in the kernel. |
776 | ||
b6b90b68 | 777 | |
179dd12c AS |
778 | strongswan-4.2.4 |
779 | ---------------- | |
780 | ||
9de95037 AS |
781 | - Added statistics functions to ipsec pool --status and ipsec pool --leases |
782 | and input validation checks to various ipsec pool commands. | |
179dd12c | 783 | |
73a8eed3 | 784 | - ipsec statusall now lists all loaded charon plugins and displays |
9de95037 | 785 | the negotiated IKEv2 cipher suite proposals. |
73a8eed3 AS |
786 | |
787 | - The openssl plugin supports the elliptic curve Diffie-Hellman groups | |
788 | 19, 20, 21, 25, and 26. | |
789 | ||
790 | - The openssl plugin supports ECDSA authentication using elliptic curve | |
791 | X.509 certificates. | |
792 | ||
793 | - Fixed a bug in stroke which caused multiple charon threads to close | |
794 | the file descriptors during packet transfers over the stroke socket. | |
b6b90b68 | 795 | |
e0bb4dbb AS |
796 | - ESP sequence numbers are now migrated in IPsec SA updates handled by |
797 | MOBIKE. Works only with Linux kernels >= 2.6.17. | |
798 | ||
179dd12c | 799 | |
83d9e870 AS |
800 | strongswan-4.2.3 |
801 | ---------------- | |
802 | ||
b6b90b68 | 803 | - Fixed the strongswan.conf path configuration problem that occurred when |
83d9e870 AS |
804 | --sysconfig was not set explicitly in ./configure. |
805 | ||
806 | - Fixed a number of minor bugs that where discovered during the 4th | |
807 | IKEv2 interoperability workshop in San Antonio, TX. | |
808 | ||
809 | ||
7f491111 MW |
810 | strongswan-4.2.2 |
811 | ---------------- | |
812 | ||
a57cd446 AS |
813 | - Plugins for libstrongswan and charon can optionally be loaded according |
814 | to a configuration in strongswan.conf. Most components provide a | |
7f491111 | 815 | "load = " option followed by a space separated list of plugins to load. |
a57cd446 AS |
816 | This allows e.g. the fallback from a hardware crypto accelerator to |
817 | to software-based crypto plugins. | |
7f491111 MW |
818 | |
819 | - Charons SQL plugin has been extended by a virtual IP address pool. | |
a57cd446 AS |
820 | Configurations with a rightsourceip=%poolname setting query a SQLite or |
821 | MySQL database for leases. The "ipsec pool" command helps in administrating | |
822 | the pool database. See ipsec pool --help for the available options | |
823 | ||
824 | - The Authenticated Encryption Algorithms AES-CCM-8/12/16 and AES-GCM-8/12/16 | |
b6b90b68 | 825 | for ESP are now supported starting with the Linux 2.6.25 kernel. The |
a57cd446 AS |
826 | syntax is e.g. esp=aes128ccm12 or esp=aes256gcm16. |
827 | ||
7f491111 | 828 | |
5c5d67d6 AS |
829 | strongswan-4.2.1 |
830 | ---------------- | |
831 | ||
c306dfb1 | 832 | - Support for "Hash and URL" encoded certificate payloads has been implemented |
b1f8fc0c TB |
833 | in the IKEv2 daemon charon. Using the "certuribase" option of a CA section |
834 | allows to assign a base URL to all certificates issued by the specified CA. | |
835 | The final URL is then built by concatenating that base and the hex encoded | |
836 | SHA1 hash of the DER encoded certificate. Note that this feature is disabled | |
837 | by default and must be enabled using the option "charon.hash_and_url". | |
5c5d67d6 | 838 | |
58caabf7 MW |
839 | - The IKEv2 daemon charon now supports the "uniqueids" option to close multiple |
840 | IKE_SAs with the same peer. The option value "keep" prefers existing | |
841 | connection setups over new ones, where the value "replace" replaces existing | |
842 | connections. | |
b6b90b68 MW |
843 | |
844 | - The crypto factory in libstrongswan additionaly supports random number | |
58caabf7 | 845 | generators, plugins may provide other sources of randomness. The default |
c306dfb1 | 846 | plugin reads raw random data from /dev/(u)random. |
58caabf7 | 847 | |
b6b90b68 | 848 | - Extended the credential framework by a caching option to allow plugins |
58caabf7 | 849 | persistent caching of fetched credentials. The "cachecrl" option has been |
c306dfb1 | 850 | re-implemented. |
58caabf7 MW |
851 | |
852 | - The new trustchain verification introduced in 4.2.0 has been parallelized. | |
853 | Threads fetching CRL or OCSP information no longer block other threads. | |
5c5d67d6 | 854 | |
58caabf7 MW |
855 | - A new IKEv2 configuration attribute framework has been introduced allowing |
856 | plugins to provide virtual IP addresses, and in the future, other | |
857 | configuration attribute services (e.g. DNS/WINS servers). | |
5c5d67d6 | 858 | |
466abb49 | 859 | - The stroke plugin has been extended to provide virtual IP addresses from |
58caabf7 MW |
860 | a pool defined in ipsec.conf. The "rightsourceip" parameter now accepts |
861 | address pools in CIDR notation (e.g. 10.1.1.0/24). The parameter also accepts | |
862 | the value "%poolname", where "poolname" identifies a pool provided by a | |
466abb49 | 863 | separate plugin. |
58caabf7 | 864 | |
c306dfb1 | 865 | - Fixed compilation on uClibc and a couple of other minor bugs. |
58caabf7 | 866 | |
c306dfb1 | 867 | - Set DPD defaults in ipsec starter to dpd_delay=30s and dpd_timeout=150s. |
466abb49 AS |
868 | |
869 | - The IKEv1 pluto daemon now supports the ESP encryption algorithm CAMELLIA | |
c306dfb1 | 870 | with key lengths of 128, 192, and 256 bits, as well as the authentication |
466abb49 AS |
871 | algorithm AES_XCBC_MAC. Configuration example: esp=camellia192-aesxcbc. |
872 | ||
5c5d67d6 | 873 | |
a11ea97d AS |
874 | strongswan-4.2.0 |
875 | ---------------- | |
876 | ||
16f5dacd MW |
877 | - libstrongswan has been modularized to attach crypto algorithms, |
878 | credential implementations (keys, certificates) and fetchers dynamically | |
879 | through plugins. Existing code has been ported to plugins: | |
880 | - RSA/Diffie-Hellman implementation using the GNU Multi Precision library | |
881 | - X509 certificate system supporting CRLs, OCSP and attribute certificates | |
882 | - Multiple plugins providing crypto algorithms in software | |
883 | - CURL and OpenLDAP fetcher | |
a11ea97d | 884 | |
16f5dacd MW |
885 | - libstrongswan gained a relational database API which uses pluggable database |
886 | providers. Plugins for MySQL and SQLite are available. | |
887 | ||
888 | - The IKEv2 keying daemon charon is more extensible. Generic plugins may provide | |
889 | connection configuration, credentials and EAP methods or control the daemon. | |
890 | Existing code has been ported to plugins: | |
891 | - EAP-AKA, EAP-SIM, EAP-MD5 and EAP-Identity | |
892 | - stroke configuration, credential and control (compatible to pluto) | |
893 | - XML bases management protocol to control and query the daemon | |
894 | The following new plugins are available: | |
895 | - An experimental SQL configuration, credential and logging plugin on | |
896 | top of either MySQL or SQLite | |
897 | - A unit testing plugin to run tests at daemon startup | |
898 | ||
899 | - The authentication and credential framework in charon has been heavily | |
900 | refactored to support modular credential providers, proper | |
901 | CERTREQ/CERT payload exchanges and extensible authorization rules. | |
902 | ||
b6b90b68 | 903 | - The framework of strongSwan Manager has envolved to the web application |
16f5dacd MW |
904 | framework libfast (FastCGI Application Server w/ Templates) and is usable |
905 | by other applications. | |
b6b90b68 | 906 | |
a11ea97d | 907 | |
6859f760 AS |
908 | strongswan-4.1.11 |
909 | ----------------- | |
fb6d76cd | 910 | |
a561f74d AS |
911 | - IKE rekeying in NAT situations did not inherit the NAT conditions |
912 | to the rekeyed IKE_SA so that the UDP encapsulation was lost with | |
913 | the next CHILD_SA rekeying. | |
914 | ||
915 | - Wrong type definition of the next_payload variable in id_payload.c | |
b6b90b68 | 916 | caused an INVALID_SYNTAX error on PowerPC platforms. |
fb6d76cd | 917 | |
e6b50b3f AS |
918 | - Implemented IKEv2 EAP-SIM server and client test modules that use |
919 | triplets stored in a file. For details on the configuration see | |
920 | the scenario 'ikev2/rw-eap-sim-rsa'. | |
921 | ||
fb6d76cd | 922 | |
83e0d841 AS |
923 | strongswan-4.1.10 |
924 | ----------------- | |
925 | ||
926 | - Fixed error in the ordering of the certinfo_t records in the ocsp cache that | |
b6b90b68 | 927 | caused multiple entries of the same serial number to be created. |
83e0d841 | 928 | |
fdc7c943 MW |
929 | - Implementation of a simple EAP-MD5 module which provides CHAP |
930 | authentication. This may be interesting in conjunction with certificate | |
931 | based server authentication, as weak passwords can't be brute forced | |
932 | (in contradiction to traditional IKEv2 PSK). | |
933 | ||
934 | - A complete software based implementation of EAP-AKA, using algorithms | |
935 | specified in 3GPP2 (S.S0055). This implementation does not use an USIM, | |
936 | but reads the secrets from ipsec.secrets. Make sure to read eap_aka.h | |
937 | before using it. | |
938 | ||
939 | - Support for vendor specific EAP methods using Expanded EAP types. The | |
b6b90b68 | 940 | interface to EAP modules has been slightly changed, so make sure to |
fdc7c943 | 941 | check the changes if you're already rolling your own modules. |
83e0d841 | 942 | |
fb6d76cd | 943 | |
5076770c AS |
944 | strongswan-4.1.9 |
945 | ---------------- | |
946 | ||
800b3356 AS |
947 | - The default _updown script now dynamically inserts and removes ip6tables |
948 | firewall rules if leftfirewall=yes is set in IPv6 connections. New IPv6 | |
949 | net-net and roadwarrior (PSK/RSA) scenarios for both IKEv1 and IKEV2 were | |
950 | added. | |
5076770c | 951 | |
6f274c2a MW |
952 | - Implemented RFC4478 repeated authentication to force EAP/Virtual-IP clients |
953 | to reestablish an IKE_SA within a given timeframe. | |
954 | ||
955 | - strongSwan Manager supports configuration listing, initiation and termination | |
956 | of IKE and CHILD_SAs. | |
957 | ||
958 | - Fixes and improvements to multithreading code. | |
959 | ||
8b678ad4 | 960 | - IKEv2 plugins have been renamed to libcharon-* to avoid naming conflicts. |
b6b90b68 | 961 | Make sure to remove the old plugins in $libexecdir/ipsec, otherwise they get |
8b678ad4 | 962 | loaded twice. |
5076770c | 963 | |
83e0d841 | 964 | |
b82e8231 AS |
965 | strongswan-4.1.8 |
966 | ---------------- | |
967 | ||
5076770c | 968 | - Removed recursive pthread mutexes since uClibc doesn't support them. |
b82e8231 AS |
969 | |
970 | ||
a4a3632c AS |
971 | strongswan-4.1.7 |
972 | ---------------- | |
973 | ||
974 | - In NAT traversal situations and multiple queued Quick Modes, | |
975 | those pending connections inserted by auto=start after the | |
976 | port floating from 500 to 4500 were erronously deleted. | |
977 | ||
6e193274 | 978 | - Added a "forceencaps" connection parameter to enforce UDP encapsulation |
078b6008 | 979 | to surmount restrictive firewalls. NAT detection payloads are faked to |
6e193274 MW |
980 | simulate a NAT situation and trick the other peer into NAT mode (IKEv2 only). |
981 | ||
982 | - Preview of strongSwan Manager, a web based configuration and monitoring | |
983 | application. It uses a new XML control interface to query the IKEv2 daemon | |
64d24679 | 984 | (see http://wiki.strongswan.org/wiki/Manager). |
6e193274 MW |
985 | |
986 | - Experimental SQLite configuration backend which will provide the configuration | |
987 | interface for strongSwan Manager in future releases. | |
988 | ||
989 | - Further improvements to MOBIKE support. | |
990 | ||
a4a3632c | 991 | |
3dcf9dbd AS |
992 | strongswan-4.1.6 |
993 | ---------------- | |
994 | ||
3eac4dfd AS |
995 | - Since some third party IKEv2 implementations run into |
996 | problems with strongSwan announcing MOBIKE capability per | |
997 | default, MOBIKE can be disabled on a per-connection-basis | |
998 | using the mobike=no option. Whereas mobike=no disables the | |
999 | sending of the MOBIKE_SUPPORTED notification and the floating | |
1000 | to UDP port 4500 with the IKE_AUTH request even if no NAT | |
1001 | situation has been detected, strongSwan will still support | |
1002 | MOBIKE acting as a responder. | |
1003 | ||
1004 | - the default ipsec routing table plus its corresponding priority | |
1005 | used for inserting source routes has been changed from 100 to 220. | |
1006 | It can be configured using the --with-ipsec-routing-table and | |
b6b90b68 MW |
1007 | --with-ipsec-routing-table-prio options. |
1008 | ||
bdc0b55b AS |
1009 | - the --enable-integrity-test configure option tests the |
1010 | integrity of the libstrongswan crypto code during the charon | |
1011 | startup. | |
b6b90b68 | 1012 | |
3eac4dfd AS |
1013 | - the --disable-xauth-vid configure option disables the sending |
1014 | of the XAUTH vendor ID. This can be used as a workaround when | |
1015 | interoperating with some Windows VPN clients that get into | |
1016 | trouble upon reception of an XAUTH VID without eXtended | |
1017 | AUTHentication having been configured. | |
b6b90b68 | 1018 | |
f872f9d1 AS |
1019 | - ipsec stroke now supports the rereadsecrets, rereadaacerts, |
1020 | rereadacerts, and listacerts options. | |
3dcf9dbd AS |
1021 | |
1022 | ||
7ad634a2 AS |
1023 | strongswan-4.1.5 |
1024 | ---------------- | |
1025 | ||
1026 | - If a DNS lookup failure occurs when resolving right=%<FQDN> | |
1027 | or right=<FQDN> combined with rightallowany=yes then the | |
1028 | connection is not updated by ipsec starter thus preventing | |
1029 | the disruption of an active IPsec connection. Only if the DNS | |
1030 | lookup successfully returns with a changed IP address the | |
1031 | corresponding connection definition is updated. | |
1032 | ||
8f5b363c MW |
1033 | - Routes installed by the keying daemons are now in a separate |
1034 | routing table with the ID 100 to avoid conflicts with the main | |
1035 | table. Route lookup for IKEv2 traffic is done in userspace to ignore | |
1036 | routes installed for IPsec, as IKE traffic shouldn't get encapsulated. | |
1037 | ||
7ad634a2 | 1038 | |
e93c68ba AS |
1039 | strongswan-4.1.4 |
1040 | ---------------- | |
1041 | ||
1042 | - The pluto IKEv1 daemon now exhibits the same behaviour as its | |
1043 | IKEv2 companion charon by inserting an explicit route via the | |
1044 | _updown script only if a sourceip exists. This is admissible | |
1045 | since routing through the IPsec tunnel is handled automatically | |
b7af55ac AS |
1046 | by NETKEY's IPsec policies. As a consequence the left|rightnexthop |
1047 | parameter is not required any more. | |
078ce348 AS |
1048 | |
1049 | - The new IKEv1 parameter right|leftallowany parameters helps to handle | |
1050 | the case where both peers possess dynamic IP addresses that are | |
1051 | usually resolved using DynDNS or a similar service. The configuration | |
1052 | ||
1053 | right=peer.foo.bar | |
1054 | rightallowany=yes | |
1055 | ||
1056 | can be used by the initiator to start up a connection to a peer | |
1057 | by resolving peer.foo.bar into the currently allocated IP address. | |
1058 | Thanks to the rightallowany flag the connection behaves later on | |
1059 | as | |
1060 | ||
1061 | right=%any | |
1062 | ||
1063 | so that the peer can rekey the connection as an initiator when his | |
1fbdab85 AS |
1064 | IP address changes. An alternative notation is |
1065 | ||
1066 | right=%peer.foo.bar | |
1067 | ||
1068 | which will implicitly set rightallowany=yes. | |
1069 | ||
1070 | - ipsec starter now fails more gracefully in the presence of parsing | |
1071 | errors. Flawed ca and conn section are discarded and pluto is started | |
1072 | if non-fatal errors only were encountered. If right=%peer.foo.bar | |
1073 | cannot be resolved by DNS then right=%any will be used so that passive | |
1074 | connections as a responder are still possible. | |
078ce348 | 1075 | |
a0a0bdd7 AS |
1076 | - The new pkcs11initargs parameter that can be placed in the |
1077 | setup config section of /etc/ipsec.conf allows the definition | |
1078 | of an argument string that is used with the PKCS#11 C_Initialize() | |
1079 | function. This non-standard feature is required by the NSS softoken | |
1080 | library. This patch was contributed by Robert Varga. | |
b6b90b68 | 1081 | |
a0a0bdd7 AS |
1082 | - Fixed a bug in ipsec starter introduced by strongswan-2.8.5 |
1083 | which caused a segmentation fault in the presence of unknown | |
1084 | or misspelt keywords in ipsec.conf. This bug fix was contributed | |
1085 | by Robert Varga. | |
1086 | ||
e3606f2b MW |
1087 | - Partial support for MOBIKE in IKEv2. The initiator acts on interface/ |
1088 | address configuration changes and updates IKE and IPsec SAs dynamically. | |
e93c68ba | 1089 | |
06651827 | 1090 | |
a3354a69 AS |
1091 | strongswan-4.1.3 |
1092 | ---------------- | |
1093 | ||
b6b90b68 | 1094 | - IKEv2 peer configuration selection now can be based on a given |
35d4809c AS |
1095 | certification authority using the rightca= statement. |
1096 | ||
1097 | - IKEv2 authentication based on RSA signatures now can handle multiple | |
41e16cf4 AS |
1098 | certificates issued for a given peer ID. This allows a smooth transition |
1099 | in the case of a peer certificate renewal. | |
a3354a69 | 1100 | |
998ca0ea MW |
1101 | - IKEv2: Support for requesting a specific virtual IP using leftsourceip on the |
1102 | client and returning requested virtual IPs using rightsourceip=%config | |
1103 | on the server. If the server does not support configuration payloads, the | |
1104 | client enforces its leftsourceip parameter. | |
1105 | ||
1106 | - The ./configure options --with-uid/--with-gid allow pluto and charon | |
1107 | to drop their privileges to a minimum and change to an other UID/GID. This | |
1108 | improves the systems security, as a possible intruder may only get the | |
1109 | CAP_NET_ADMIN capability. | |
1110 | ||
b6b90b68 | 1111 | - Further modularization of charon: Pluggable control interface and |
998ca0ea MW |
1112 | configuration backend modules provide extensibility. The control interface |
1113 | for stroke is included, and further interfaces using DBUS (NetworkManager) | |
1114 | or XML are on the way. A backend for storing configurations in the daemon | |
b6b90b68 | 1115 | is provided and more advanced backends (using e.g. a database) are trivial |
998ca0ea | 1116 | to implement. |
a3354a69 | 1117 | |
41e16cf4 AS |
1118 | - Fixed a compilation failure in libfreeswan occuring with Linux kernel |
1119 | headers > 2.6.17. | |

1124 | ||
e23d98a7 | 1125 | - Support for an additional Diffie-Hellman exchange when creating/rekeying |
37fb0355 MW |
1126 | a CHILD_SA in IKEv2 (PFS). PFS is enabled when the proposal contains a |
1127 | DH group (e.g. "esp=aes128-sha1-modp1536"). Further, DH group negotiation | |
1128 | is implemented properly for rekeying. | |
1129 | ||
1130 | - Support for the AES-XCBC-96 MAC algorithm for IPsec SAs when using IKEv2 | |
1131 | (requires linux >= 2.6.20). It is enabled using e.g. "esp=aes256-aesxcbc". | |
1132 | ||
d931f465 MW |
1133 | - Working IPv4-in-IPv6 and IPv6-in-IPv4 tunnels for linux >= 2.6.21. |
1134 | ||
37fb0355 MW |
1135 | - Added support for EAP modules which do not establish an MSK. |
1136 | ||
dfbe2a0f | 1137 | - Removed the dependencies from the /usr/include/linux/ headers by |
9f78f957 | 1138 | including xfrm.h, ipsec.h, and pfkeyv2.h in the distribution. |
b6b90b68 | 1139 | |
9f78f957 AS |
1140 | - crlNumber is now listed by ipsec listcrls |
1141 | ||
8ea7b96f AS |
1142 | - The xauth_modules.verify_secret() function now passes the |
1143 | connection name. | |
1144 | ||
e23d98a7 | 1145 | |
ed284399 MW |
1146 | strongswan-4.1.1 |
1147 | ---------------- | |
1148 | ||
1149 | - Server side cookie support. If to may IKE_SAs are in CONNECTING state, | |
1150 | cookies are enabled and protect against DoS attacks with faked source | |
1151 | addresses. Number of IKE_SAs in CONNECTING state is also limited per | |
1152 | peer address to avoid resource exhaustion. IKE_SA_INIT messages are | |
1153 | compared to properly detect retransmissions and incoming retransmits are | |
1154 | detected even if the IKE_SA is blocked (e.g. doing OCSP fetches). | |
1155 | ||
db88e37d AS |
1156 | - The IKEv2 daemon charon now supports dynamic http- and ldap-based CRL |
1157 | fetching enabled by crlcheckinterval > 0 and caching fetched CRLs | |
1158 | enabled by cachecrls=yes. | |
1159 | ||
3b4f7d92 AS |
1160 | - Added the configuration options --enable-nat-transport which enables |
1161 | the potentially insecure NAT traversal for IPsec transport mode and | |
1162 | --disable-vendor-id which disables the sending of the strongSwan | |
1163 | vendor ID. | |
1164 | ||
1165 | - Fixed a long-standing bug in the pluto IKEv1 daemon which caused | |
1166 | a segmentation fault if a malformed payload was detected in the | |
1167 | IKE MR2 message and pluto tried to send an encrypted notification | |
1168 | message. | |
1169 | ||
46b9ff68 AS |
1170 | - Added the NATT_IETF_02_N Vendor ID in order to support IKEv1 connections |
1171 | with Windows 2003 Server which uses a wrong VID hash. | |
1172 | ||
3b4f7d92 | 1173 | |
34bbd0c3 | 1174 | strongswan-4.1.0 |
cd3958f8 AS |
1175 | ---------------- |
1176 | ||
1177 | - Support of SHA2_384 hash function for protecting IKEv1 | |
1178 | negotiations and support of SHA2 signatures in X.509 certificates. | |
1179 | ||
1180 | - Fixed a serious bug in the computation of the SHA2-512 HMAC | |
1181 | function. Introduced automatic self-test of all IKEv1 hash | |
1182 | and hmac functions during pluto startup. Failure of a self-test | |
1183 | currently issues a warning only but does not exit pluto [yet]. | |
1184 | ||
9b45443d MW |
1185 | - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2. |
1186 | ||
c5d0fbb6 | 1187 | - Full support of CA information sections. ipsec listcainfos |
b6b90b68 | 1188 | now shows all collected crlDistributionPoints and OCSP |
c5d0fbb6 AS |
1189 | accessLocations. |
1190 | ||
69ed04bf AS |
1191 | - Support of the Online Certificate Status Protocol (OCSP) for IKEv2. |
1192 | This feature requires the HTTP fetching capabilities of the libcurl | |
1193 | library which must be enabled by setting the --enable-http configure | |
1194 | option. | |
1195 | ||
9b45443d MW |
1196 | - Refactored core of the IKEv2 message processing code, allowing better |
1197 | code reuse and separation. | |
1198 | ||
1199 | - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration | |
1200 | payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted | |
1201 | by the requestor and installed in a resolv.conf file. | |
1202 | ||
1203 | - The IKEv2 daemon charon installs a route for each IPsec policy to use | |
1204 | the correct source address even if an application does not explicitly | |
1205 | specify it. | |
1206 | ||
1207 | - Integrated the EAP framework into charon which loads pluggable EAP library | |
1208 | modules. The ipsec.conf parameter authby=eap initiates EAP authentication | |
1209 | on the client side, while the "eap" parameter on the server side defines | |
1210 | the EAP method to use for client authentication. | |
1211 | A generic client side EAP-Identity module and an EAP-SIM authentication | |
1212 | module using a third party card reader implementation are included. | |
1213 | ||
1214 | - Added client side support for cookies. | |
1215 | ||
1216 | - Integrated the fixes done at the IKEv2 interoperability bakeoff, including | |
1217 | strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor | |
1218 | fixes to enhance interoperability with other implementations. | |

1c266d7d AS |
1221 | strongswan-4.0.7 |
1222 | ---------------- | |
1223 | ||
6fdf5f44 AS |
1224 | - strongSwan now interoperates with the NCP Secure Entry Client, |
1225 | the Shrew Soft VPN Client, and the Cisco VPN client, doing both | |
1226 | XAUTH and Mode Config. | |
1c266d7d AS |
1227 | |
1228 | - UNITY attributes are now recognized and UNITY_BANNER is set | |
1229 | to a default string. | |
1230 | ||
1231 | ||
2b4405a3 MW |
1232 | strongswan-4.0.6 |
1233 | ---------------- | |
1234 | ||
e38a15d4 AS |
1235 | - IKEv1: Support for extended authentication (XAUTH) in combination |
1236 | with ISAKMP Main Mode RSA or PSK authentication. Both client and | |
1237 | server side were implemented. Handling of user credentials can | |
1238 | be done by a run-time loadable XAUTH module. By default user | |
b6b90b68 MW |
1239 | credentials are stored in ipsec.secrets. |
1240 | ||
2b4405a3 MW |
1241 | - IKEv2: Support for reauthentication when rekeying |
1242 | ||
5903179b | 1243 | - IKEv2: Support for transport mode |
af87afed | 1244 | |
5903179b | 1245 | - fixed a lot of bugs related to byte order |
2b4405a3 | 1246 | |
5903179b | 1247 | - various other bugfixes |
2b4405a3 MW |
1248 | |
1249 | ||
0cd645d2 AS |
1250 | strongswan-4.0.5 |
1251 | ---------------- | |
1252 | ||
1253 | - IKEv1: Implementation of ModeConfig push mode via the new connection | |
1254 | keyword modeconfig=push allows interoperability with Cisco VPN gateways. | |
1255 | ||
1256 | - IKEv1: The command ipsec statusall now shows "DPD active" for all | |
1257 | ISAKMP SAs that are under active Dead Peer Detection control. | |
1258 | ||
1259 | - IKEv2: Charon's logging and debugging framework has been completely rewritten. | |
1260 | Instead of logger, special printf() functions are used to directly | |
1261 | print objects like hosts (%H) identifications (%D), certificates (%Q), | |
1262 | etc. The number of debugging levels have been reduced to: | |
03bf883d | 1263 | |
0cd645d2 | 1264 | 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private) |
03bf883d | 1265 | |
0cd645d2 AS |
1266 | The debugging levels can either be specified statically in ipsec.conf as |
1267 | ||
1268 | config setup | |
03bf883d | 1269 | charondebug="lib 1, cfg 3, net 2" |
0cd645d2 | 1270 | |
03bf883d | 1271 | or changed at runtime via stroke as |
0cd645d2 | 1272 | |
03bf883d | 1273 | ipsec stroke loglevel cfg 2 |
0cd645d2 AS |

48dc3934 MW |
1276 | strongswan-4.0.4 |
1277 | ---------------- | |
1278 | ||
1279 | - Implemented full support for IPv6-in-IPv6 tunnels. | |
1280 | ||
1281 | - Added configuration options for dead peer detection in IKEv2. dpd_action | |
1282 | types "clear", "hold" and "restart" are supported. The dpd_timeout | |
1283 | value is not used, as the normal retransmission policy applies to | |
1284 | detect dead peers. The dpd_delay parameter enables sending of empty | |
1285 | informational message to detect dead peers in case of inactivity. | |
1286 | ||
1287 | - Added support for preshared keys in IKEv2. PSK keys configured in | |
1288 | ipsec.secrets are loaded. The authby parameter specifies the authentication | |
1289 | method to authentificate ourself, the other peer may use PSK or RSA. | |
1290 | ||
1291 | - Changed retransmission policy to respect the keyingtries parameter. | |
1292 | ||
112ad7c3 AS |
1293 | - Added private key decryption. PEM keys encrypted with AES-128/192/256 |
1294 | or 3DES are supported. | |
48dc3934 MW |
1295 | |
1296 | - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to | |
1297 | encrypt IKE traffic. | |
1298 | ||
1299 | - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates | |
1300 | signed with such a hash algorithm. | |
1301 | ||
1302 | - Added initial support for updown scripts. The actions up-host/client and | |
1303 | down-host/client are executed. The leftfirewall=yes parameter | |
1304 | uses the default updown script to insert dynamic firewall rules, a custom | |
1305 | updown script may be specified with the leftupdown parameter. | |
1306 | ||
1307 | ||
a1310b6b MW |
1308 | strongswan-4.0.3 |
1309 | ---------------- | |
1310 | ||
1311 | - Added support for the auto=route ipsec.conf parameter and the | |
b6b90b68 MW |
1312 | ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and |
1313 | CHILD_SAs dynamically on demand when traffic is detected by the | |
a1310b6b MW |
1314 | kernel. |
1315 | ||
1316 | - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter. | |
1317 | As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only | |
1318 | new keys are generated using perfect forward secrecy. An optional flag | |
1319 | which enforces reauthentication will be implemented later. | |
1320 | ||
b425d998 AS |
1321 | - "sha" and "sha1" are now treated as synonyms in the ike= and esp= |
1322 | algorithm configuration statements. | |
1323 | ||
1324 | ||
bf4df11f AS |
1325 | strongswan-4.0.2 |
1326 | ---------------- | |
1327 | ||
623d3dcf AS |
1328 | - Full X.509 certificate trust chain verification has been implemented. |
1329 | End entity certificates can be exchanged via CERT payloads. The current | |
1330 | default is leftsendcert=always, since CERTREQ payloads are not supported | |
1331 | yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls. | |
efa40c11 | 1332 | |
b6b90b68 | 1333 | - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2 |
efa40c11 | 1334 | would offer more possibilities for traffic selection, but the Linux kernel |
b6b90b68 | 1335 | currently does not support it. That's why we stick with these simple |
efa40c11 MW |
1336 | ipsec.conf rules for now. |
1337 | ||
623d3dcf AS |
1338 | - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no |
1339 | IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear, | |
1340 | dpddelay=60s). | |
1341 | ||
efa40c11 MW |
1342 | - Initial NAT traversal support in IKEv2. Charon includes NAT detection |
1343 | notify payloads to detect NAT routers between the peers. It switches | |
1344 | to port 4500, uses UDP encapsulated ESP packets, handles peer address | |
1345 | changes gracefully and sends keep alive message periodically. | |
1346 | ||
b6b90b68 MW |
1347 | - Reimplemented IKE_SA state machine for charon, which allows simultaneous |
1348 | rekeying, more shared code, cleaner design, proper retransmission | |
efa40c11 MW |
1349 | and a more extensible code base. |
1350 | ||
cfd8b27f AS |
1351 | - The mixed PSK/RSA roadwarrior detection capability introduced by the |
1352 | strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal | |
1353 | payloads by the responder right before any defined IKE Main Mode state had | |
1354 | been established. Although any form of bad proposal syntax was being correctly | |
1355 | detected by the payload parser, the subsequent error handler didn't check | |
1356 | the state pointer before logging current state information, causing an | |
1357 | immediate crash of the pluto keying daemon due to a NULL pointer. | |
1358 | ||
bf4df11f | 1359 | |
7e81e975 MW |
1360 | strongswan-4.0.1 |
1361 | ---------------- | |
1362 | ||
b6b90b68 | 1363 | - Added algorithm selection to charon: New default algorithms for |
c15c3d4b MW |
1364 | ike=aes128-sha-modp2048, as both daemons support it. The default |
1365 | for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles | |
1366 | the ike/esp parameter the same way as pluto. As this syntax does | |
b6b90b68 | 1367 | not allow specification of a pseudo random function, the same |
c15c3d4b MW |
1368 | algorithm as for integrity is used (currently sha/md5). Supported |
1369 | algorithms for IKE: | |
1370 | Encryption: aes128, aes192, aes256 | |
1371 | Integrity/PRF: md5, sha (using hmac) | |
1372 | DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192 | |
1373 | and for ESP: | |
b6b90b68 | 1374 | Encryption: aes128, aes192, aes256, 3des, blowfish128, |
c15c3d4b MW |
1375 | blowfish192, blowfish256 |
1376 | Integrity: md5, sha1 | |
1377 | More IKE encryption algorithms will come after porting libcrypto into | |
b6b90b68 | 1378 | libstrongswan. |
f2c2d395 | 1379 | |
c15c3d4b MW |
1380 | - initial support for rekeying CHILD_SAs using IKEv2. Currently no |
1381 | perfect forward secrecy is used. The rekeying parameters rekey, | |
22ff6f57 | 1382 | rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported |
c15c3d4b MW |
1383 | when using IKEv2. WARNING: charon currently is unable to handle |
1384 | simultaneous rekeying. To avoid such a situation, use a large | |
1385 | rekeyfuzz, or even better, set rekey=no on one peer. | |
22ff6f57 | 1386 | |
7e81e975 MW |
1387 | - support for host2host, net2net, host2net (roadwarrior) tunnels |
1388 | using predefined RSA certificates (see uml scenarios for | |
1389 | configuration examples). | |
1390 | ||
f2c2d395 MW |
1391 | - new build environment featuring autotools. Features such |
1392 | as HTTP, LDAP and smartcard support may be enabled using | |
b6b90b68 | 1393 | the ./configure script. Changing install directories |
f2c2d395 MW |
1394 | is possible, too. See ./configure --help for more details. |
1395 | ||
22ff6f57 MW |
1396 | - better integration of charon with ipsec starter, which allows |
1397 | (almost) transparent operation with both daemons. charon | |
1398 | handles ipsec commands up, down, status, statusall, listall, | |
1399 | listcerts and allows proper load, reload and delete of connections | |
1400 | via ipsec starter. | |
1401 | ||
b425d998 | 1402 | |
9820c0e2 MW |
1403 | strongswan-4.0.0 |
1404 | ---------------- | |
1405 | ||
1406 | - initial support of the IKEv2 protocol. Connections in | |
b6b90b68 | 1407 | ipsec.conf designated by keyexchange=ikev2 are negotiated |
9820c0e2 MW |
1408 | by the new IKEv2 charon keying daemon whereas those marked |
1409 | by keyexchange=ikev1 or the default keyexchange=ike are | |
1410 | handled thy the IKEv1 pluto keying daemon. Currently only | |
1411 | a limited subset of functions are available with IKEv2 | |
1412 | (Default AES encryption, authentication based on locally | |
1413 | imported X.509 certificates, unencrypted private RSA keys | |
1414 | in PKCS#1 file format, limited functionality of the ipsec | |
1415 | status command). | |
1416 | ||
1417 | ||
997358a6 MW |
1418 | strongswan-2.7.0 |
1419 | ---------------- | |
1420 | ||
1421 | - the dynamic iptables rules from the _updown_x509 template | |
1422 | for KLIPS and the _updown_policy template for NETKEY have | |
1423 | been merged into the default _updown script. The existing | |
1424 | left|rightfirewall keyword causes the automatic insertion | |
1425 | and deletion of ACCEPT rules for tunneled traffic upon | |
1426 | the successful setup and teardown of an IPsec SA, respectively. | |
1427 | left|rightfirwall can be used with KLIPS under any Linux 2.4 | |
1428 | kernel or with NETKEY under a Linux kernel version >= 2.6.16 | |
1429 | in conjuction with iptables >= 1.3.5. For NETKEY under a Linux | |
1430 | kernel version < 2.6.16 which does not support IPsec policy | |
1431 | matching yet, please continue to use a copy of the _updown_espmark | |
1432 | template loaded via the left|rightupdown keyword. | |
1433 | ||
1434 | - a new left|righthostaccess keyword has been introduced which | |
1435 | can be used in conjunction with left|rightfirewall and the | |
1436 | default _updown script. By default leftfirewall=yes inserts | |
1437 | a bi-directional iptables FORWARD rule for a local client network | |
1438 | with a netmask different from 255.255.255.255 (single host). | |
1439 | This does not allow to access the VPN gateway host via its | |
1440 | internal network interface which is part of the client subnet | |
1441 | because an iptables INPUT and OUTPUT rule would be required. | |
1442 | lefthostaccess=yes will cause this additional ACCEPT rules to | |
b6b90b68 | 1443 | be inserted. |
997358a6 MW |
1444 | |
1445 | - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal | |
1446 | payload is preparsed in order to find out whether the roadwarrior | |
1447 | requests PSK or RSA so that a matching connection candidate can | |
1448 | be found. | |
1449 | ||
1450 | ||
1451 | strongswan-2.6.4 | |
1452 | ---------------- | |
1453 | ||
1454 | - the new _updown_policy template allows ipsec policy based | |
1455 | iptables firewall rules. Required are iptables version | |
1456 | >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes | |
b6b90b68 | 1457 | the _updown_espmark template, so that no INPUT mangle rules |
997358a6 MW |
1458 | are required any more. |
1459 | ||
1460 | - added support of DPD restart mode | |
1461 | ||
1462 | - ipsec starter now allows the use of wildcards in include | |
1463 | statements as e.g. in "include /etc/my_ipsec/*.conf". | |
1464 | Patch courtesy of Matthias Haas. | |
1465 | ||
1466 | - the Netscape OID 'employeeNumber' is now recognized and can be | |
1467 | used as a Relative Distinguished Name in certificates. | |
1468 | ||
1469 | ||
1470 | strongswan-2.6.3 | |
1471 | ---------------- | |
1472 | ||
b6b90b68 | 1473 | - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec |
997358a6 MW |
1474 | command and not of ipsec setup any more. |
1475 | ||
1476 | - ipsec starter now supports AH authentication in conjunction with | |
1477 | ESP encryption. AH authentication is configured in ipsec.conf | |
1478 | via the auth=ah parameter. | |
b6b90b68 | 1479 | |
997358a6 MW |
1480 | - The command ipsec scencrypt|scdecrypt <args> is now an alias for |
1481 | ipsec whack --scencrypt|scdecrypt <args>. | |
1482 | ||
1483 | - get_sa_info() now determines for the native netkey IPsec stack | |
1484 | the exact time of the last use of an active eroute. This information | |
1485 | is used by the Dead Peer Detection algorithm and is also displayed by | |
1486 | the ipsec status command. | |

997358a6 MW |
1488 | |
1489 | strongswan-2.6.2 | |
1490 | ---------------- | |
1491 | ||
1492 | - running under the native Linux 2.6 IPsec stack, the function | |
1493 | get_sa_info() is called by ipsec auto --status to display the current | |
1494 | number of transmitted bytes per IPsec SA. | |
1495 | ||
1496 | - get_sa_info() is also used by the Dead Peer Detection process to detect | |
1497 | recent ESP activity. If ESP traffic was received from the peer within | |
1498 | the last dpd_delay interval then no R_Y_THERE notification must be sent. | |
1499 | ||
1500 | - strongSwan now supports the Relative Distinguished Name "unstructuredName" | |
1501 | in ID_DER_ASN1_DN identities. The following notations are possible: | |
1502 | ||
1503 | rightid="unstructuredName=John Doe" | |
1504 | rightid="UN=John Doe" | |
1505 | ||
1506 | - fixed a long-standing bug which caused PSK-based roadwarrior connections | |
1507 | to segfault in the function id.c:same_id() called by keys.c:get_secret() | |
1508 | if an FQDN, USER_FQDN, or Key ID was defined, as in the following example. | |
1509 | ||
1510 | conn rw | |
1511 | right=%any | |
1512 | rightid=@foo.bar | |
1513 | authby=secret | |
1514 | ||
1515 | - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall). | |
1516 | ||
1517 | - ipsec starter didn't set host_addr and client.addr ports in whack msg. | |
1518 | ||
1519 | - in order to guarantee backwards-compatibility with the script-based | |
1520 | auto function (e.g. auto --replace), the ipsec starter scripts stores | |
1521 | the defaultroute information in the temporary file /var/run/ipsec.info. | |
1522 | ||
1523 | - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH | |
1524 | Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config | |
1525 | servers. | |
1526 | ||
1527 | - the ipsec starter now also recognizes the parameters authby=never and | |
1528 | type=passthrough|pass|drop|reject. | |
1529 | ||
1530 | ||
1531 | strongswan-2.6.1 | |
1532 | ---------------- | |
1533 | ||
1534 | - ipsec starter now supports the also parameter which allows | |
1535 | a modular structure of the connection definitions. Thus | |
1536 | "ipsec start" is now ready to replace "ipsec setup". | |
1537 | ||
1538 | ||
1539 | strongswan-2.6.0 | |
1540 | ---------------- | |
1541 | ||
1542 | - Mathieu Lafon's popular ipsec starter tool has been added to the | |
1543 | strongSwan distribution. Many thanks go to Stephan Scholz from astaro | |
1544 | for his integration work. ipsec starter is a C program which is going | |
1545 | to replace the various shell and awk starter scripts (setup, _plutoload, | |
1546 | _plutostart, _realsetup, _startklips, _confread, and auto). Since | |
1547 | ipsec.conf is now parsed only once, the starting of multiple tunnels is | |
1548 | accelerated tremedously. | |
1549 | ||
1550 | - Added support of %defaultroute to the ipsec starter. If the IP address | |
b6b90b68 | 1551 | changes, a HUP signal to the ipsec starter will automatically |
997358a6 MW |
1552 | reload pluto's connections. |
1553 | ||
1554 | - moved most compile time configurations from pluto/Makefile to | |
1555 | Makefile.inc by defining the options USE_LIBCURL, USE_LDAP, | |
1556 | USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE. | |
1557 | ||
1558 | - removed the ipsec verify and ipsec newhostkey commands | |
1559 | ||
1560 | - fixed some 64-bit issues in formatted print statements | |
1561 | ||
1562 | - The scepclient functionality implementing the Simple Certificate | |
1563 | Enrollment Protocol (SCEP) is nearly complete but hasn't been | |
1564 | documented yet. | |
1565 | ||
1566 | ||
1567 | strongswan-2.5.7 | |
1568 | ---------------- | |
1569 | ||
1570 | - CA certicates are now automatically loaded from a smartcard | |
1571 | or USB crypto token and appear in the ipsec auto --listcacerts | |
1572 | listing. | |
1573 | ||
1574 | ||
1575 | strongswan-2.5.6 | |
1576 | ---------------- | |
1577 | ||
1578 | - when using "ipsec whack --scencrypt <data>" with a PKCS#11 | |
1579 | library that does not support the C_Encrypt() Cryptoki | |
1580 | function (e.g. OpenSC), the RSA encryption is done in | |
1581 | software using the public key fetched from the smartcard. | |
1582 | ||
b6b90b68 | 1583 | - The scepclient function now allows to define the |
997358a6 MW |
1584 | validity of a self-signed certificate using the --days, |
1585 | --startdate, and --enddate options. The default validity | |
1586 | has been changed from one year to five years. | |
1587 | ||
1588 | ||
1589 | strongswan-2.5.5 | |
1590 | ---------------- | |
1591 | ||
1592 | - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11 | |
1593 | interface to other applications for RSA encryption and decryption | |
1594 | via the whack interface. Notation: | |
1595 | ||
1596 | ipsec whack --scencrypt <data> | |
1597 | [--inbase 16|hex|64|base64|256|text|ascii] | |
1598 | [--outbase 16|hex|64|base64|256|text|ascii] | |
1599 | [--keyid <keyid>] | |
1600 | ||
1601 | ipsec whack --scdecrypt <data> | |
1602 | [--inbase 16|hex|64|base64|256|text|ascii] | |
1603 | [--outbase 16|hex|64|base64|256|text|ascii] | |
1604 | [--keyid <keyid>] | |
1605 | ||
b6b90b68 | 1606 | The default setting for inbase and outbase is hex. |
997358a6 MW |
1607 | |
1608 | The new proxy interface can be used for securing symmetric | |
1609 | encryption keys required by the cryptoloop or dm-crypt | |
1610 | disk encryption schemes, especially in the case when | |
1611 | pkcs11keepstate=yes causes pluto to lock the pkcs11 slot | |
1612 | permanently. | |
1613 | ||
1614 | - if the file /etc/ipsec.secrets is lacking during the startup of | |
1615 | pluto then the root-readable file /etc/ipsec.d/private/myKey.der | |
1616 | containing a 2048 bit RSA private key and a matching self-signed | |
1617 | certificate stored in the file /etc/ipsec.d/certs/selfCert.der | |
1618 | is automatically generated by calling the function | |
1619 | ||
1620 | ipsec scepclient --out pkcs1 --out cert-self | |
1621 | ||
1622 | scepclient was written by Jan Hutter and Martin Willi, students | |
1623 | at the University of Applied Sciences in Rapperswil, Switzerland. | |
1624 | ||
1625 | ||
1626 | strongswan-2.5.4 | |
1627 | ---------------- | |
1628 | ||
1629 | - the current extension of the PKCS#7 framework introduced | |
1630 | a parsing error in PKCS#7 wrapped X.509 certificates that are | |
1631 | e.g. transmitted by Windows XP when multi-level CAs are used. | |
1632 | the parsing syntax has been fixed. | |
1633 | ||
1634 | - added a patch by Gerald Richter which tolerates multiple occurrences | |
1635 | of the ipsec0 interface when using KLIPS. | |
1636 | ||
1637 | ||
1638 | strongswan-2.5.3 | |
1639 | ---------------- | |
1640 | ||
1641 | - with gawk-3.1.4 the word "default2 has become a protected | |
1642 | keyword for use in switch statements and cannot be used any | |
1643 | more in the strongSwan scripts. This problem has been | |
1644 | solved by renaming "default" to "defaults" and "setdefault" | |
1645 | in the scripts _confread and auto, respectively. | |
1646 | ||
1647 | - introduced the parameter leftsendcert with the values | |
1648 | ||
1649 | always|yes (the default, always send a cert) | |
1650 | ifasked (send the cert only upon a cert request) | |
1651 | never|no (never send a cert, used for raw RSA keys and | |
b6b90b68 | 1652 | self-signed certs) |
997358a6 MW |
1653 | |
1654 | - fixed the initialization of the ESP key length to a default of | |
1655 | 128 bits in the case that the peer does not send a key length | |
1656 | attribute for AES encryption. | |
1657 | ||
1658 | - applied Herbert Xu's uniqueIDs patch | |
1659 | ||
1660 | - applied Herbert Xu's CLOEXEC patches | |
1661 | ||
1662 | ||
1663 | strongswan-2.5.2 | |
1664 | ---------------- | |
1665 | ||
1666 | - CRLs can now be cached also in the case when the issuer's | |
1667 | certificate does not contain a subjectKeyIdentifier field. | |
1668 | In that case the subjectKeyIdentifier is computed by pluto as the | |
1669 | 160 bit SHA-1 hash of the issuer's public key in compliance | |
1670 | with section 4.2.1.2 of RFC 3280. | |
1671 | ||
1672 | - Fixed a bug introduced by strongswan-2.5.1 which eliminated | |
1673 | not only multiple Quick Modes of a given connection but also | |
1674 | multiple connections between two security gateways. | |
1675 | ||
1676 | ||
1677 | strongswan-2.5.1 | |
1678 | ---------------- | |
1679 | ||
1680 | - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute | |
1681 | installed either by setting auto=route in ipsec.conf or by | |
1682 | a connection put into hold, generates an XFRM_AQUIRE event | |
1683 | for each packet that wants to use the not-yet exisiting | |
1684 | tunnel. Up to now each XFRM_AQUIRE event led to an entry in | |
1685 | the Quick Mode queue, causing multiple IPsec SA to be | |
1686 | established in rapid succession. Starting with strongswan-2.5.1 | |
1687 | only a single IPsec SA is established per host-pair connection. | |
1688 | ||
1689 | - Right after loading the PKCS#11 module, all smartcard slots are | |
1690 | searched for certificates. The result can be viewed using | |
1691 | the command | |
1692 | ||
1693 | ipsec auto --listcards | |
1694 | ||
1695 | The certificate objects found in the slots are numbered | |
1696 | starting with #1, #2, etc. This position number can be used to address | |
1697 | certificates (leftcert=%smartcard) and keys (: PIN %smartcard) | |
1698 | in ipsec.conf and ipsec.secrets, respectively: | |
1699 | ||
1700 | %smartcard (selects object #1) | |
1701 | %smartcard#1 (selects object #1) | |
1702 | %smartcard#3 (selects object #3) | |
1703 | ||
1704 | As an alternative the existing retrieval scheme can be used: | |
1705 | ||
1706 | %smartcard:45 (selects object with id=45) | |
1707 | %smartcard0 (selects first object in slot 0) | |
1708 | %smartcard4:45 (selects object in slot 4 with id=45) | |
1709 | ||
1710 | - Depending on the settings of CKA_SIGN and CKA_DECRYPT | |
1711 | private key flags either C_Sign() or C_Decrypt() is used | |
1712 | to generate a signature. | |
1713 | ||
1714 | - The output buffer length parameter siglen in C_Sign() | |
1715 | is now initialized to the actual size of the output | |
1716 | buffer prior to the function call. This fixes the | |
1717 | CKR_BUFFER_TOO_SMALL error that could occur when using | |
1718 | the OpenSC PKCS#11 module. | |
1719 | ||
1720 | - Changed the initialization of the PKCS#11 CK_MECHANISM in | |
1721 | C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }. | |
1722 | ||
1723 | - Refactored the RSA public/private key code and transferred it | |
1724 | from keys.c to the new pkcs1.c file as a preparatory step | |
1725 | towards the release of the SCEP client. | |
1726 | ||
1727 | ||
1728 | strongswan-2.5.0 | |
1729 | ---------------- | |
1730 | ||
1731 | - The loading of a PKCS#11 smartcard library module during | |
1732 | runtime does not require OpenSC library functions any more | |
1733 | because the corresponding code has been integrated into | |
1734 | smartcard.c. Also the RSAREF pkcs11 header files have been | |
1735 | included in a newly created pluto/rsaref directory so that | |
1736 | no external include path has to be defined any longer. | |
1737 | ||
1738 | - A long-awaited feature has been implemented at last: | |
1739 | The local caching of CRLs fetched via HTTP or LDAP, activated | |
1740 | by the parameter cachecrls=yes in the config setup section | |
1741 | of ipsec.conf. The dynamically fetched CRLs are stored under | |
1742 | a unique file name containing the issuer's subjectKeyID | |
1743 | in /etc/ipsec.d/crls. | |
b6b90b68 | 1744 | |
997358a6 MW |
1745 | - Applied a one-line patch courtesy of Michael Richardson |
1746 | from the Openswan project which fixes the kernel-oops | |
1747 | in KLIPS when an snmp daemon is running on the same box. | |
1748 | ||
1749 | ||
1750 | strongswan-2.4.4 | |
1751 | ---------------- | |
1752 | ||
1753 | - Eliminated null length CRL distribution point strings. | |
1754 | ||
1755 | - Fixed a trust path evaluation bug introduced with 2.4.3 | |
1756 | ||
1757 | ||
1758 | strongswan-2.4.3 | |
1759 | ---------------- | |
1760 | ||
1761 | - Improved the joint OCSP / CRL revocation policy. | |
1762 | OCSP responses have precedence over CRL entries. | |
1763 | ||
1764 | - Introduced support of CRLv2 reason codes. | |
1765 | ||
1766 | - Fixed a bug with key-pad equipped readers which caused | |
1767 | pluto to prompt for the pin via the console when the first | |
1768 | occasion to enter the pin via the key-pad was missed. | |
1769 | ||
1770 | - When pluto is built with LDAP_V3 enabled, the library | |
1771 | liblber required by newer versions of openldap is now | |
1772 | included. | |
1773 | ||
1774 | ||
1775 | strongswan-2.4.2 | |
1776 | ---------------- | |
1777 | ||
1778 | - Added the _updown_espmark template which requires all | |
1779 | incoming ESP traffic to be marked with a default mark | |
1780 | value of 50. | |
b6b90b68 | 1781 | |
997358a6 MW |
1782 | - Introduced the pkcs11keepstate parameter in the config setup |
1783 | section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11 | |
b6b90b68 | 1784 | session and login states are kept as long as possible during |
997358a6 MW |
1785 | the lifetime of pluto. This means that a PIN entry via a key |
1786 | pad has to be done only once. | |
1787 | ||
1788 | - Introduced the pkcs11module parameter in the config setup | |
1789 | section of ipsec.conf which specifies the PKCS#11 module | |
1790 | to be used with smart cards. Example: | |
b6b90b68 | 1791 | |
997358a6 | 1792 | pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo |
b6b90b68 | 1793 | |
997358a6 MW |
1794 | - Added support of smartcard readers equipped with a PIN pad. |
1795 | ||
1796 | - Added patch by Jay Pfeifer which detects when netkey | |
1797 | modules have been statically built into the Linux 2.6 kernel. | |
1798 | ||
1799 | - Added two patches by Herbert Xu. The first uses ip xfrm | |
1800 | instead of setkey to flush the IPsec policy database. The | |
1801 | second sets the optional flag in inbound IPComp SAs only. | |
b6b90b68 | 1802 | |
997358a6 MW |
1803 | - Applied Ulrich Weber's patch which fixes an interoperability |
1804 | problem between native IPsec and KLIPS systems caused by | |
1805 | setting the replay window to 32 instead of 0 for ipcomp. | |
1806 | ||
1807 | ||
1808 | strongswan-2.4.1 | |
1809 | ---------------- | |
1810 | ||
1811 | - Fixed a bug which caused an unwanted Mode Config request | |
1812 | to be initiated in the case where "right" was used to denote | |
1813 | the local side in ipsec.conf and "left" the remote side, | |
1814 | contrary to the recommendation that "right" be remote and | |
1815 | "left" be"local". | |
1816 | ||
1817 | ||
1818 | strongswan-2.4.0a | |
1819 | ----------------- | |
1820 | ||
1821 | - updated Vendor ID to strongSwan-2.4.0 | |
1822 | ||
1823 | - updated copyright statement to include David Buechi and | |
1824 | Michael Meier | |
b6b90b68 MW |
1825 | |
1826 | ||
997358a6 MW |
1827 | strongswan-2.4.0 |
1828 | ---------------- | |
1829 | ||
1830 | - strongSwan now communicates with attached smartcards and | |
1831 | USB crypto tokens via the standardized PKCS #11 interface. | |
1832 | By default the OpenSC library from www.opensc.org is used | |
1833 | but any other PKCS#11 library could be dynamically linked. | |
1834 | strongSwan's PKCS#11 API was implemented by David Buechi | |
1835 | and Michael Meier, both graduates of the Zurich University | |
1836 | of Applied Sciences in Winterthur, Switzerland. | |
1837 | ||
1838 | - When a %trap eroute is triggered by an outgoing IP packet | |
1839 | then the native IPsec stack of the Linux 2.6 kernel [often/ | |
1840 | always?] returns an XFRM_ACQUIRE message with an undefined | |
1841 | protocol family field and the connection setup fails. | |
1842 | As a workaround IPv4 (AF_INET) is now assumed. | |
b6b90b68 MW |
1843 | |
1844 | - the results of the UML test scenarios are now enhanced | |
997358a6 | 1845 | with block diagrams of the virtual network topology used |
b6b90b68 | 1846 | in a particular test. |
997358a6 MW |
1847 | |
1848 | ||
1849 | strongswan-2.3.2 | |
1850 | ---------------- | |
1851 | ||
1852 | - fixed IV used to decrypt informational messages. | |
1853 | This bug was introduced with Mode Config functionality. | |
b6b90b68 | 1854 | |
997358a6 MW |
1855 | - fixed NCP Vendor ID. |
1856 | ||
1857 | - undid one of Ulrich Weber's maximum udp size patches | |
1858 | because it caused a segmentation fault with NAT-ed | |
1859 | Delete SA messages. | |
b6b90b68 | 1860 | |
997358a6 MW |
1861 | - added UML scenarios wildcards and attr-cert which |
1862 | demonstrate the implementation of IPsec policies based | |
1863 | on wildcard parameters contained in Distinguished Names and | |
1864 | on X.509 attribute certificates, respectively. | |
1865 | ||
1866 | ||
1867 | strongswan-2.3.1 | |
1868 | ---------------- | |
1869 | ||
1870 | - Added basic Mode Config functionality | |
1871 | ||
1872 | - Added Mathieu Lafon's patch which upgrades the status of | |
1873 | the NAT-Traversal implementation to RFC 3947. | |
b6b90b68 | 1874 | |
997358a6 MW |
1875 | - The _startklips script now also loads the xfrm4_tunnel |
1876 | module. | |
b6b90b68 | 1877 | |
997358a6 MW |
1878 | - Added Ulrich Weber's netlink replay window size and |
1879 | maximum udp size patches. | |
1880 | ||
1881 | - UML testing now uses the Linux 2.6.10 UML kernel by default. | |
b6b90b68 | 1882 | |
997358a6 MW |
1883 | |
1884 | strongswan-2.3.0 | |
1885 | ---------------- | |
1886 | ||
1887 | - Eric Marchionni and Patrik Rayo, both recent graduates from | |
1888 | the Zuercher Hochschule Winterthur in Switzerland, created a | |
1889 | User-Mode-Linux test setup for strongSwan. For more details | |
1890 | please read the INSTALL and README documents in the testing | |
1891 | subdirectory. | |
1892 | ||
1893 | - Full support of group attributes based on X.509 attribute | |
b6b90b68 | 1894 | certificates. Attribute certificates can be generated |
997358a6 | 1895 | using the openac facility. For more details see |
b6b90b68 | 1896 | |
997358a6 | 1897 | man ipsec_openac. |
b6b90b68 | 1898 | |
997358a6 MW |
1899 | The group attributes can be used in connection definitions |
1900 | in order to give IPsec access to specific user groups. | |
1901 | This is done with the new parameter left|rightgroups as in | |
b6b90b68 | 1902 | |
997358a6 MW |
1903 | rightgroups="Research, Sales" |
1904 | ||
1905 | giving access to users possessing the group attributes | |
1906 | Research or Sales, only. | |
1907 | ||
1908 | - In Quick Mode clients with subnet mask /32 are now | |
b6b90b68 | 1909 | coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should |
997358a6 MW |
1910 | fix rekeying problems with the SafeNet/SoftRemote and NCP |
1911 | Secure Entry Clients. | |
1912 | ||
1913 | - Changed the defaults of the ikelifetime and keylife parameters | |
1914 | to 3h and 1h, respectively. The maximum allowable values are | |
1915 | now both set to 24 h. | |
1916 | ||
1917 | - Suppressed notification wars between two IPsec peers that | |
1918 | could e.g. be triggered by incorrect ISAKMP encryption. | |
1919 | ||
1920 | - Public RSA keys can now have identical IDs if either the | |
1921 | issuing CA or the serial number is different. The serial | |
1922 | number of a certificate is now shown by the command | |
b6b90b68 | 1923 | |
997358a6 MW |
1924 | ipsec auto --listpubkeys |
1925 | ||

1927 | strongswan-2.2.2 | |
1928 | ---------------- | |
1929 | ||
1930 | - Added Tuomo Soini's sourceip feature which allows a strongSwan | |
1931 | roadwarrior to use a fixed Virtual IP (see README section 2.6) | |
1932 | and reduces the well-known four tunnel case on VPN gateways to | |
1933 | a single tunnel definition (see README section 2.4). | |
1934 | ||
1935 | - Fixed a bug occuring with NAT-Traversal enabled when the responder | |
1936 | suddenly turns initiator and the initiator cannot find a matching | |
1937 | connection because of the floated IKE port 4500. | |
b6b90b68 | 1938 | |
997358a6 MW |
1939 | - Removed misleading ipsec verify command from barf. |
1940 | ||
1941 | - Running under the native IP stack, ipsec --version now shows | |
1942 | the Linux kernel version (courtesy to the Openswan project). | |
1943 | ||
1944 | ||
1945 | strongswan-2.2.1 | |
1946 | ---------------- | |
1947 | ||
1948 | - Introduced the ipsec auto --listalgs monitoring command which lists | |
1949 | all currently registered IKE and ESP algorithms. | |
1950 | ||
1951 | - Fixed a bug in the ESP algorithm selection occuring when the strict flag | |
1952 | is set and the first proposed transform does not match. | |
b6b90b68 | 1953 | |
997358a6 MW |
1954 | - Fixed another deadlock in the use of the lock_certs_and_keys() mutex, |
1955 | occuring when a smartcard is present. | |
1956 | ||
1957 | - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event. | |
b6b90b68 | 1958 | |
997358a6 MW |
1959 | - Fixed the printing of the notification names (null) |
1960 | ||
1961 | - Applied another of Herbert Xu's Netlink patches. | |
1962 | ||
1963 | ||
1964 | strongswan-2.2.0 | |
1965 | ---------------- | |
1966 | ||
1967 | - Support of Dead Peer Detection. The connection parameter | |
1968 | ||
1969 | dpdaction=clear|hold | |
b6b90b68 | 1970 | |
997358a6 MW |
1971 | activates DPD for the given connection. |
1972 | ||
1973 | - The default Opportunistic Encryption (OE) policy groups are not | |
1974 | automatically included anymore. Those wishing to activate OE can include | |
1975 | the policy group with the following statement in ipsec.conf: | |
b6b90b68 | 1976 | |
997358a6 | 1977 | include /etc/ipsec.d/examples/oe.conf |
b6b90b68 | 1978 | |
997358a6 MW |
1979 | The default for [right|left]rsasigkey is now set to %cert. |
1980 | ||
1981 | - strongSwan now has a Vendor ID of its own which can be activated | |
1982 | using the compile option VENDORID | |
1983 | ||
1984 | - Applied Herbert Xu's patch which sets the compression algorithm correctly. | |
1985 | ||
1986 | - Applied Herbert Xu's patch fixing an ESPINUDP problem | |
1987 | ||
1988 | - Applied Herbert Xu's patch setting source/destination port numbers. | |
1989 | ||
1990 | - Reapplied one of Herbert Xu's NAT-Traversal patches which got | |
1991 | lost during the migration from SuperFreeS/WAN. | |
b6b90b68 | 1992 | |
997358a6 MW |
1993 | - Fixed a deadlock in the use of the lock_certs_and_keys() mutex. |

1998 | |
1999 | strongswan-2.1.5 | |
2000 | ---------------- | |
2001 | ||
2002 | - Thomas Walpuski made me aware of a potential DoS attack via | |
2003 | a PKCS#7-wrapped certificate bundle which could overwrite valid CA | |
2004 | certificates in Pluto's authority certificate store. This vulnerability | |
2005 | was fixed by establishing trust in CA candidate certificates up to a | |
2006 | trusted root CA prior to insertion into Pluto's chained list. | |
2007 | ||
2008 | - replaced the --assign option by the -v option in the auto awk script | |
2009 | in order to make it run with mawk under debian/woody. | |
2010 | ||
2011 | ||
2012 | strongswan-2.1.4 | |
2013 | ---------------- | |
2014 | ||
2015 | - Split of the status information between ipsec auto --status (concise) | |
2016 | and ipsec auto --statusall (verbose). Both commands can be used with | |
2017 | an optional connection selector: | |
2018 | ||
2019 | ipsec auto --status[all] <connection_name> | |
2020 | ||
2021 | - Added the description of X.509 related features to the ipsec_auto(8) | |
2022 | man page. | |
2023 | ||
2024 | - Hardened the ASN.1 parser in debug mode, especially the printing | |
2025 | of malformed distinguished names. | |
2026 | ||
2027 | - The size of an RSA public key received in a certificate is now restricted to | |
2028 | ||
2029 | 512 bits <= modulus length <= 8192 bits. | |
2030 | ||
2031 | - Fixed the debug mode enumeration. | |
2032 | ||
2033 | ||
2034 | strongswan-2.1.3 | |
2035 | ---------------- | |
2036 | ||
2037 | - Fixed another PKCS#7 vulnerability which could lead to an | |
2038 | endless loop while following the X.509 trust chain. | |
b6b90b68 | 2039 | |
997358a6 MW |
2040 | |
2041 | strongswan-2.1.2 | |
2042 | ---------------- | |
2043 | ||
2044 | - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski | |
2045 | that accepted end certificates having identical issuer and subject | |
2046 | distinguished names in a multi-tier X.509 trust chain. | |
b6b90b68 | 2047 | |
997358a6 MW |
2048 | |
2049 | strongswan-2.1.1 | |
2050 | ---------------- | |
2051 | ||
2052 | - Removed all remaining references to ipsec_netlink.h in KLIPS. | |
2053 | ||
2054 | ||
2055 | strongswan-2.1.0 | |
2056 | ---------------- | |
2057 | ||
2058 | - The new "ca" section allows to define the following parameters: | |
2059 | ||
2060 | ca kool | |
2061 | cacert=koolCA.pem # cacert of kool CA | |
2062 | ocspuri=http://ocsp.kool.net:8001 # ocsp server | |
2063 | ldapserver=ldap.kool.net # default ldap server | |
2064 | crluri=http://www.kool.net/kool.crl # crl distribution point | |
2065 | crluri2="ldap:///O=Kool, C= .." # crl distribution point #2 | |
2066 | auto=add # add, ignore | |
b6b90b68 | 2067 | |
997358a6 | 2068 | The ca definitions can be monitored via the command |
b6b90b68 | 2069 | |
997358a6 MW |
2070 | ipsec auto --listcainfos |
2071 | ||
2072 | - Fixed cosmetic corruption of /proc filesystem by integrating | |
2073 | D. Hugh Redelmeier's freeswan-2.06 kernel fixes. | |
2074 | ||
2075 | ||
2076 | strongswan-2.0.2 | |
2077 | ---------------- | |
2078 | ||
2079 | - Added support for the 818043 NAT-Traversal update of Microsoft's | |
2080 | Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode. | |
b6b90b68 MW |
2081 | |
2082 | - A symbolic link to libcrypto is now added in the kernel sources | |
997358a6 | 2083 | during kernel compilation |
b6b90b68 | 2084 | |
997358a6 MW |
2085 | - Fixed a couple of 64 bit issues (mostly casts to int). |
2086 | Thanks to Ken Bantoft who checked my sources on a 64 bit platform. | |
2087 | ||
2088 | - Replaced s[n]printf() statements in the kernel by ipsec_snprintf(). | |
2089 | Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro | |
2090 | of the FreeS/WAN team who solved this problem with the 2.4.25 kernel. | |
2091 | ||
2092 | ||
2093 | strongswan-2.0.1 | |
2094 | ---------------- | |
2095 | ||
2096 | - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName | |
2097 | certificate extension which contains no generalName item) can cause | |
2098 | a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has | |
2099 | been hardened to make it more robust against malformed ASN.1 objects. | |
2100 | ||
2101 | - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native | |
2102 | Linux 2.6 IPsec stack. | |
