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 | ||
107ea60f TB |
12 | - Job priorities were introduced to prevent thread starvation caused by too |
13 | many threads handling blocking operations (such as CRL fetching). Refer to | |
14 | strongswan.conf(5) for details. | |
15 | ||
16 | - Two new strongswan.conf options allow to fine-tune performance on IKEv2 | |
17 | gateways by dropping IKE_SA_INIT requests on high load. | |
18 | ||
f8799170 | 19 | - IKEv2 charon daemon supports start PASS and DROP shunt policies |
b18a697a | 20 | preventing traffic to go through IPsec connections. Installation of the |
107ea60f TB |
21 | shunt policies either via the XFRM netfilter or PFKEYv2 IPsec kernel |
22 | interfaces. | |
f8799170 | 23 | |
93095183 TB |
24 | - The history of policies installed in the kernel is now tracked so that e.g. |
25 | trap policies are correctly updated when reauthenticated SAs are terminated. | |
26 | ||
b18a697a AS |
27 | - IMC/IMV Scanner pair implementing the RFC 5792 PA-TNC (IF-M) protocol. |
28 | Using "netstat -l" the IMC scans open listening ports on the TNC client | |
29 | and sends a port list to the IMV which based on a port policy decides if | |
30 | the client is admitted to the network. | |
31 | (--enable-imc-scanner/--enable-imv-scanner). | |
32 | ||
33 | - IMC/IMV Test pair implementing the RFC 5792 PA-TNC (IF-M) protocol. | |
5d179d19 AS |
34 | (--enable-imc-test/--enable-imv-test). |
35 | ||
4876f896 MW |
36 | - The IKEv2 close action does not use the same value as the ipsec.conf dpdaction |
37 | setting, but the value defined by its own closeaction keyword. The action | |
38 | is triggered if the remote peer closes a CHILD_SA unexpectedly. | |
5d179d19 | 39 | |
6f2378c1 AS |
40 | strongswan-4.5.2 |
41 | ---------------- | |
42 | ||
320e98c2 MW |
43 | - The whitelist plugin for the IKEv2 daemon maintains an in-memory identity |
44 | whitelist. Any connection attempt of peers not whitelisted will get rejected. | |
45 | The 'ipsec whitelist' utility provides a simple command line frontend for | |
46 | whitelist administration. | |
47 | ||
92ebb7c5 | 48 | - The duplicheck plugin provides a specialized form of duplicate checking, |
5832d505 | 49 | doing a liveness check on the old SA and optionally notify a third party |
92ebb7c5 MW |
50 | application about detected duplicates. |
51 | ||
52 | - The coupling plugin permanently couples two or more devices by limiting | |
53 | authentication to previously used certificates. | |
54 | ||
6f2378c1 AS |
55 | - In the case that the peer config and child config don't have the same name |
56 | (usually in SQL database defined connections), ipsec up|route <peer config> | |
57 | starts|routes all associated child configs and ipsec up|route <child config> | |
58 | only starts|routes the specific child config. | |
59 | ||
6ca05fe2 AS |
60 | - fixed the encoding and parsing of X.509 certificate policy statements (CPS). |
61 | ||
1ee7440b AS |
62 | - Duncan Salerno contributed the eap-sim-pcsc plugin implementing a |
63 | pcsc-lite based SIM card backend. | |
64 | ||
65 | - The eap-peap plugin implements the EAP PEAP protocol. Interoperates | |
2778b664 | 66 | successfully with a FreeRADIUS server and Windows 7 Agile VPN clients. |
1ee7440b | 67 | |
cf6ca6d7 MW |
68 | - The IKEv2 daemon charon rereads strongswan.conf on SIGHUP and instructs |
69 | all plugins to reload. Currently only the eap-radius and the attr plugins | |
70 | support configuration reloading. | |
71 | ||
d3d21c29 MW |
72 | - Added userland support to the IKEv2 daemon for Extended Sequence Numbers |
73 | support coming with Linux 2.6.39. To enable ESN on a connection, add | |
74 | the 'esn' keyword to the proposal. The default proposal uses 32-bit sequence | |
75 | numbers only ('noesn'), and the same value is used if no ESN mode is | |
76 | specified. To negotiate ESN support with the peer, include both, e.g. | |
77 | esp=aes128-sha1-esn-noesn. | |
78 | ||
79 | - In addition to ESN, Linux 2.6.39 gained support for replay windows larger | |
80 | than 32 packets. The new global strongswan.conf option 'charon.replay_window' | |
81 | configures the size of the replay window, in packets. | |
82 | ||

84 | strongswan-4.5.1 |
85 | ---------------- | |
86 | ||
1b7e081b AS |
87 | - Sansar Choinyambuu implemented the RFC 5793 Posture Broker Protocol (BP) |
88 | compatible with Trusted Network Connect (TNC). The TNCCS 2.0 protocol | |
5cdaafef | 89 | requires the tnccs_20, tnc_imc and tnc_imv plugins but does not depend |
1b7e081b AS |
90 | on the libtnc library. Any available IMV/IMC pairs conforming to the |
91 | Trusted Computing Group's TNC-IF-IMV/IMC 1.2 interface specification | |
e44817df | 92 | can be loaded via /etc/tnc_config. |
1b7e081b | 93 | |
5cdaafef AS |
94 | - Re-implemented the TNCCS 1.1 protocol by using the tnc_imc and tnc_imv |
95 | in place of the external libtnc library. | |
96 | ||
97 | - The tnccs_dynamic plugin loaded on a TNC server in addition to the | |
98 | tnccs_11 and tnccs_20 plugins, dynamically detects the IF-TNCCS | |
99 | protocol version used by a TNC client and invokes an instance of | |
100 | the corresponding protocol stack. | |
101 | ||
41ba5ce7 AS |
102 | - IKE and ESP proposals can now be stored in an SQL database using a |
103 | new proposals table. The start_action field in the child_configs | |
104 | tables allows the automatic starting or routing of connections stored | |
105 | in an SQL database. | |
106 | ||
1b7e081b AS |
107 | - The new certificate_authorities and certificate_distribution_points |
108 | tables make it possible to store CRL and OCSP Certificate Distribution | |
109 | points in an SQL database. | |
110 | ||
ae09bc62 TB |
111 | - The new 'include' statement allows to recursively include other files in |
112 | strongswan.conf. Existing sections and values are thereby extended and | |
113 | replaced, respectively. | |
114 | ||
115 | - Due to the changes in the parser for strongswan.conf, the configuration | |
116 | syntax for the attr plugin has changed. Previously, it was possible to | |
117 | specify multiple values of a specific attribute type by adding multiple | |
118 | key/value pairs with the same key (e.g. dns) to the plugins.attr section. | |
119 | Because values with the same key now replace previously defined values | |
120 | this is not possible anymore. As an alternative, multiple values can be | |
121 | specified by separating them with a comma (e.g. dns = 1.2.3.4, 2.3.4.5). | |
122 | ||
840e7044 AS |
123 | - ipsec listalgs now appends (set in square brackets) to each crypto |
124 | algorithm listed the plugin that registered the function. | |
125 | ||
e44817df MW |
126 | - Traffic Flow Confidentiality padding supported with Linux 2.6.38 can be used |
127 | by the IKEv2 daemon. The ipsec.conf 'tfc' keyword pads all packets to a given | |
128 | boundary, the special value '%mtu' pads all packets to the path MTU. | |
129 | ||
78a547c9 MW |
130 | - The new af-alg plugin can use various crypto primitives of the Linux Crypto |
131 | API using the AF_ALG interface introduced with 2.6.38. This removes the need | |
132 | for additional userland implementations of symmetric cipher, hash, hmac and | |
133 | xcbc algorithms. | |
44582075 | 134 | |
41ed0294 | 135 | - The IKEv2 daemon supports the INITIAL_CONTACT notify as initiator and |
983a5e88 MW |
136 | responder. The notify is sent when initiating configurations with a unique |
137 | policy, set in ipsec.conf via the global 'uniqueids' option. | |
41ed0294 | 138 | |
f0783464 MW |
139 | - The conftest conformance testing framework enables the IKEv2 stack to perform |
140 | many tests using a distinct tool and configuration frontend. Various hooks | |
141 | can alter reserved bits, flags, add custom notifies and proposals, reorder | |
142 | or drop messages and much more. It is enabled using the --enable-conftest | |
143 | ./configure switch. | |
144 | ||
77eee25f MW |
145 | - The new libstrongswan constraints plugin provides advanced X.509 constraint |
146 | checking. In additon to X.509 pathLen constraints, the plugin checks for | |
147 | nameConstraints and certificatePolicies, including policyMappings and | |
148 | policyConstraints. The x509 certificate plugin and the pki tool have been | |
96c4addc MW |
149 | enhanced to support these extensions. The new left/rightcertpolicy ipsec.conf |
150 | connection keywords take OIDs a peer certificate must have. | |
151 | ||
152 | - The left/rightauth ipsec.conf keywords accept values with a minimum strength | |
153 | for trustchain public keys in bits, such as rsa-2048 or ecdsa-256. | |
77eee25f | 154 | |
fb1e7df1 MW |
155 | - The revocation and x509 libstrongswan plugins and the pki tool gained basic |
156 | support for delta CRLs. | |
157 | ||

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

cdad91de MW |
363 | - Using extensions (such as BEET mode) and crypto algorithms (such as twofish, |
364 | serpent, sha256_96) allocated in the private use space now require that we | |
365 | know its meaning, i.e. we are talking to strongSwan. Use the new | |
366 | "charon.send_vendor_id" option in strongswan.conf to let the remote peer know | |
367 | this is the case. | |
368 | ||
aca9f9ab MW |
369 | - Experimental support for draft-eronen-ipsec-ikev2-eap-auth, where the |
370 | responder omits public key authentication in favor of a mutual authentication | |
371 | method. To enable EAP-only authentication, set rightauth=eap on the responder | |
372 | to rely only on the MSK constructed AUTH payload. This not-yet standardized | |
373 | extension requires the strongSwan vendor ID introduced above. | |
374 | ||
0a975307 AS |
375 | - The IKEv1 daemon ignores the Juniper SRX notification type 40001, thus |
376 | allowing interoperability. | |
377 | ||
378 | ||
b6b90b68 MW |
379 | strongswan-4.3.5 |
380 | ---------------- | |
381 | ||
628f023d AS |
382 | - The IKEv1 pluto daemon can now use SQL-based address pools to deal out |
383 | virtual IP addresses as a Mode Config server. The pool capability has been | |
384 | migrated from charon's sql plugin to a new attr-sql plugin which is loaded | |
b42bfc79 | 385 | by libstrongswan and which can be used by both daemons either with a SQLite |
628f023d AS |
386 | or MySQL database and the corresponding plugin. |
387 | ||
b42bfc79 MW |
388 | - Plugin names have been streamlined: EAP plugins now have a dash after eap |
389 | (e.g. eap-sim), as it is used with the --enable-eap-sim ./configure option. | |
390 | Plugin configuration sections in strongswan.conf now use the same name as the | |
391 | plugin itself (i.e. with a dash). Make sure to update "load" directives and | |
392 | the affected plugin sections in existing strongswan.conf files. | |
393 | ||
d245f5cf AS |
394 | - The private/public key parsing and encoding has been split up into |
395 | separate pkcs1, pgp, pem and dnskey plugins. The public key implementation | |
396 | plugins gmp, gcrypt and openssl can all make use of them. | |
b6b90b68 | 397 | |
55b045ab MW |
398 | - The EAP-AKA plugin can use different backends for USIM/quintuplet |
399 | calculations, very similar to the EAP-SIM plugin. The existing 3GPP2 software | |
400 | implementation has been migrated to a separate plugin. | |
401 | ||
d245f5cf | 402 | - The IKEv2 daemon charon gained basic PGP support. It can use locally installed |
b6b90b68 MW |
403 | peer certificates and can issue signatures based on RSA private keys. |
404 | ||
405 | - The new 'ipsec pki' tool provides a set of commands to maintain a public | |
406 | key infrastructure. It currently supports operations to create RSA and ECDSA | |
407 | private/public keys, calculate fingerprints and issue or verify certificates. | |
408 | ||
409 | - Charon uses a monotonic time source for statistics and job queueing, behaving | |
410 | correctly if the system time changes (e.g. when using NTP). | |
411 | ||
412 | - In addition to time based rekeying, charon supports IPsec SA lifetimes based | |
413 | on processed volume or number of packets. They new ipsec.conf paramaters | |
414 | 'lifetime' (an alias to 'keylife'), 'lifebytes' and 'lifepackets' handle | |
415 | SA timeouts, while the parameters 'margintime' (an alias to rekeymargin), | |
416 | 'marginbytes' and 'marginpackets' trigger the rekeying before a SA expires. | |
417 | The existing parameter 'rekeyfuzz' affects all margins. | |
418 | ||
85af7a89 MW |
419 | - If no CA/Gateway certificate is specified in the NetworkManager plugin, |
420 | charon uses a set of trusted root certificates preinstalled by distributions. | |
421 | The directory containing CA certificates can be specified using the | |
422 | --with-nm-ca-dir=path configure option. | |
423 | ||
b80fa9ca | 424 | - Fixed the encoding of the Email relative distinguished name in left|rightid |
509f70c1 | 425 | statements. |
b80fa9ca | 426 | |
509f70c1 AS |
427 | - Fixed the broken parsing of PKCS#7 wrapped certificates by the pluto daemon. |
428 | ||
429 | - Fixed smartcard-based authentication in the pluto daemon which was broken by | |
430 | the ECDSA support introduced with the 4.3.2 release. | |
431 | ||
cea4bd8f AS |
432 | - A patch contributed by Heiko Hund fixes mixed IPv6 in IPv4 and vice versa |
433 | tunnels established with the IKEv1 pluto daemon. | |
434 | ||
509f70c1 AS |
435 | - The pluto daemon now uses the libstrongswan x509 plugin for certificates and |
436 | CRls and the struct id type was replaced by identification_t used by charon | |
437 | and the libstrongswan library. | |
18060241 | 438 | |

430dd08a AS |
440 | strongswan-4.3.4 |
441 | ---------------- | |
442 | ||
443 | - IKEv2 charon daemon ported to FreeBSD and Mac OS X. Installation details can | |
444 | be found on wiki.strongswan.org. | |
445 | ||
446 | - ipsec statusall shows the number of bytes transmitted and received over | |
447 | ESP connections configured by the IKEv2 charon daemon. | |
448 | ||
449 | - The IKEv2 charon daemon supports include files in ipsec.secrets. | |
450 | ||

1c7f456a AS |
452 | strongswan-4.3.3 |
453 | ---------------- | |
454 | ||
aa74d705 AS |
455 | - The configuration option --enable-integrity-test plus the strongswan.conf |
456 | option libstrongswan.integrity_test = yes activate integrity tests | |
457 | of the IKE daemons charon and pluto, libstrongswan and all loaded | |
458 | plugins. Thus dynamic library misconfigurations and non-malicious file | |
459 | manipulations can be reliably detected. | |
460 | ||
1c7f456a AS |
461 | - The new default setting libstrongswan.ecp_x_coordinate_only=yes allows |
462 | IKEv1 interoperability with MS Windows using the ECP DH groups 19 and 20. | |
463 | ||
464 | - The IKEv1 pluto daemon now supports the AES-CCM and AES-GCM ESP | |
465 | authenticated encryption algorithms. | |
466 | ||
aa74d705 AS |
467 | - The IKEv1 pluto daemon now supports V4 OpenPGP keys. |
468 | ||
469 | - The RDN parser vulnerability discovered by Orange Labs research team | |
470 | was not completely fixed in version 4.3.2. Some more modifications | |
471 | had to be applied to the asn1_length() function to make it robust. | |
472 | ||
1c7f456a | 473 | |
80c0710c MW |
474 | strongswan-4.3.2 |
475 | ---------------- | |
476 | ||
477 | - The new gcrypt plugin provides symmetric cipher, hasher, RNG, Diffie-Hellman | |
478 | and RSA crypto primitives using the LGPL licensed GNU gcrypt library. | |
479 | ||
480 | - libstrongswan features an integrated crypto selftest framework for registered | |
481 | algorithms. The test-vector plugin provides a first set of test vectors and | |
482 | allows pluto and charon to rely on tested crypto algorithms. | |
483 | ||
b32af120 AS |
484 | - pluto can now use all libstrongswan plugins with the exception of x509 and xcbc. |
485 | Thanks to the openssl plugin, the ECP Diffie-Hellman groups 19, 20, 21, 25, and | |
486 | 26 as well as ECDSA-256, ECDSA-384, and ECDSA-521 authentication can be used | |
487 | with IKEv1. | |
126f2130 AS |
488 | |
489 | - Applying their fuzzing tool, the Orange Labs vulnerability research team found | |
490 | another two DoS vulnerabilities, one in the rather old ASN.1 parser of Relative | |
491 | Distinguished Names (RDNs) and a second one in the conversion of ASN.1 UTCTIME | |
492 | and GENERALIZEDTIME strings to a time_t value. | |
b6b90b68 | 493 | |

3bf7c249 MW |
495 | strongswan-4.3.1 |
496 | ---------------- | |
497 | ||
498 | - The nm plugin now passes DNS/NBNS server information to NetworkManager, | |
09dbca9f | 499 | allowing a gateway administrator to set DNS/NBNS configuration on clients |
3bf7c249 MW |
500 | dynamically. |
501 | ||
09dbca9f MW |
502 | - The nm plugin also accepts CA certificates for gateway authentication. If |
503 | a CA certificate is configured, strongSwan uses the entered gateway address | |
504 | as its idenitity, requiring the gateways certificate to contain the same as | |
505 | subjectAltName. This allows a gateway administrator to deploy the same | |
506 | certificates to Windows 7 and NetworkManager clients. | |
047b2e42 | 507 | |
050cc582 AS |
508 | - The command ipsec purgeike deletes IKEv2 SAs that don't have a CHILD SA. |
509 | The command ipsec down <conn>{n} deletes CHILD SA instance n of connection | |
510 | <conn> whereas ipsec down <conn>{*} deletes all CHILD SA instances. | |
511 | The command ipsec down <conn>[n] deletes IKE SA instance n of connection | |
512 | <conn> plus dependent CHILD SAs whereas ipsec down <conn>[*] deletes all | |
513 | IKE SA instances of connection <conn>. | |
514 | ||
09dbca9f | 515 | - Fixed a regression introduced in 4.3.0 where EAP authentication calculated |
047b2e42 MW |
516 | the AUTH payload incorrectly. Further, the EAP-MSCHAPv2 MSK key derivation |
517 | has been updated to be compatible with the Windows 7 Release Candidate. | |
518 | ||
519 | - Refactored installation of triggering policies. Routed policies are handled | |
520 | outside of IKE_SAs to keep them installed in any case. A tunnel gets | |
521 | established only once, even if initiation is delayed due network outages. | |
522 | ||
050cc582 AS |
523 | - Improved the handling of multiple acquire signals triggered by the kernel. |
524 | ||
525 | - Fixed two DoS vulnerabilities in the charon daemon that were discovered by | |
526 | fuzzing techniques: 1) Sending a malformed IKE_SA_INIT request leaved an | |
527 | incomplete state which caused a null pointer dereference if a subsequent | |
528 | CREATE_CHILD_SA request was sent. 2) Sending an IKE_AUTH request with either | |
529 | a missing TSi or TSr payload caused a null pointer derefence because the | |
b6b90b68 | 530 | checks for TSi and TSr were interchanged. The IKEv2 fuzzer used was |
f3bb1bd0 | 531 | developed by the Orange Labs vulnerability research team. The tool was |
050cc582 AS |
532 | initially written by Gabriel Campana and is now maintained by Laurent Butti. |
533 | ||
047b2e42 MW |
534 | - Added support for AES counter mode in ESP in IKEv2 using the proposal |
535 | keywords aes128ctr, aes192ctr and aes256ctr. | |
536 | ||
d44fd821 | 537 | - Further progress in refactoring pluto: Use of the curl and ldap plugins |
050cc582 AS |
538 | for fetching crls and OCSP. Use of the random plugin to get keying material |
539 | from /dev/random or /dev/urandom. Use of the openssl plugin as an alternative | |
d44fd821 | 540 | to the aes, des, sha1, sha2, and md5 plugins. The blowfish, twofish, and |
050cc582 | 541 | serpent encryption plugins are now optional and are not enabled by default. |
d44fd821 AS |
542 | |
543 | ||
247e665a AS |
544 | strongswan-4.3.0 |
545 | ---------------- | |
546 | ||
81fc8e5f MW |
547 | - Support for the IKEv2 Multiple Authentication Exchanges extension (RFC4739). |
548 | Initiators and responders can use several authentication rounds (e.g. RSA | |
549 | followed by EAP) to authenticate. The new ipsec.conf leftauth/rightauth and | |
550 | leftauth2/rightauth2 parameters define own authentication rounds or setup | |
551 | constraints for the remote peer. See the ipsec.conf man page for more detials. | |
552 | ||
553 | - If glibc printf hooks (register_printf_function) are not available, | |
554 | strongSwan can use the vstr string library to run on non-glibc systems. | |
555 | ||
558c89e7 AS |
556 | - The IKEv2 charon daemon can now configure the ESP CAMELLIA-CBC cipher |
557 | (esp=camellia128|192|256). | |
247e665a | 558 | |
558c89e7 AS |
559 | - Refactored the pluto and scepclient code to use basic functions (memory |
560 | allocation, leak detective, chunk handling, printf_hooks, strongswan.conf | |
561 | attributes, ASN.1 parser, etc.) from the libstrongswan library. | |
b752f873 | 562 | |
558c89e7 AS |
563 | - Up to two DNS and WINS servers to be sent via IKEv1 ModeConfig can be |
564 | configured in the pluto section of strongswan.conf. | |

623bca40 AS |
567 | strongswan-4.2.14 |
568 | ----------------- | |
569 | ||
22180558 | 570 | - The new server-side EAP RADIUS plugin (--enable-eap-radius) |
f3bb1bd0 | 571 | relays EAP messages to and from a RADIUS server. Successfully |
22180558 AS |
572 | tested with with a freeradius server using EAP-MD5 and EAP-SIM. |
573 | ||
79b27294 AS |
574 | - A vulnerability in the Dead Peer Detection (RFC 3706) code was found by |
575 | Gerd v. Egidy <gerd.von.egidy@intra2net.com> of Intra2net AG affecting | |
576 | all Openswan and strongSwan releases. A malicious (or expired ISAKMP) | |
577 | R_U_THERE or R_U_THERE_ACK Dead Peer Detection packet can cause the | |
578 | pluto IKE daemon to crash and restart. No authentication or encryption | |
579 | is required to trigger this bug. One spoofed UDP packet can cause the | |
580 | pluto IKE daemon to restart and be unresponsive for a few seconds while | |
581 | restarting. This DPD null state vulnerability has been officially | |
582 | registered as CVE-2009-0790 and is fixed by this release. | |
583 | ||
22180558 AS |
584 | - ASN.1 to time_t conversion caused a time wrap-around for |
585 | dates after Jan 18 03:14:07 UTC 2038 on 32-bit platforms. | |
586 | As a workaround such dates are set to the maximum representable | |
587 | time, i.e. Jan 19 03:14:07 UTC 2038. | |
588 | ||
589 | - Distinguished Names containing wildcards (*) are not sent in the | |
b6b90b68 | 590 | IDr payload anymore. |
623bca40 AS |
591 | |
592 | ||
076e7853 AS |
593 | strongswan-4.2.13 |
594 | ----------------- | |
595 | ||
596 | - Fixed a use-after-free bug in the DPD timeout section of the | |
597 | IKEv1 pluto daemon which sporadically caused a segfault. | |
598 | ||
f3bb1bd0 | 599 | - Fixed a crash in the IKEv2 charon daemon occurring with |
b6b90b68 | 600 | mixed RAM-based and SQL-based virtual IP address pools. |
076e7853 | 601 | |
f15483ef AS |
602 | - Fixed ASN.1 parsing of algorithmIdentifier objects where the |
603 | parameters field is optional. | |
604 | ||
03991bc1 MW |
605 | - Ported nm plugin to NetworkManager 7.1. |

bfde75ee | 608 | strongswan-4.2.12 |
076e7853 | 609 | ----------------- |
bfde75ee AS |
610 | |
611 | - Support of the EAP-MSCHAPv2 protocol enabled by the option | |
612 | --enable-eap-mschapv2. Requires the MD4 hash algorithm enabled | |
613 | either by --enable-md4 or --enable-openssl. | |
614 | ||
615 | - Assignment of up to two DNS and up to two WINS servers to peers via | |
b6b90b68 | 616 | the IKEv2 Configuration Payload (CP). The IPv4 or IPv6 nameserver |
bfde75ee AS |
617 | addresses are defined in strongswan.conf. |
618 | ||
619 | - The strongSwan applet for the Gnome NetworkManager is now built and | |
620 | distributed as a separate tarball under the name NetworkManager-strongswan. | |
621 | ||
b6b90b68 | 622 | |
0519ca90 AS |
623 | strongswan-4.2.11 |
624 | ----------------- | |
625 | ||
ae1ae574 AS |
626 | - Fixed ESP NULL encryption broken by the refactoring of keymat.c. |
627 | Also introduced proper initialization and disposal of keying material. | |
628 | ||
629 | - Fixed the missing listing of connection definitions in ipsec statusall | |
630 | broken by an unfortunate local variable overload. | |
0519ca90 AS |
631 | |
632 | ||
4856241c MW |
633 | strongswan-4.2.10 |
634 | ----------------- | |
635 | ||
636 | - Several performance improvements to handle thousands of tunnels with almost | |
637 | linear upscaling. All relevant data structures have been replaced by faster | |
638 | counterparts with better lookup times. | |
639 | ||
640 | - Better parallelization to run charon on multiple cores. Due to improved | |
641 | ressource locking and other optimizations the daemon can take full | |
642 | advantage of 16 or even more cores. | |
643 | ||
644 | - The load-tester plugin can use a NULL Diffie-Hellman group and simulate | |
645 | unique identities and certificates by signing peer certificates using a CA | |
646 | on the fly. | |
647 | ||
648 | - The redesigned stroke in-memory IP pool handles leases. The "ipsec leases" | |
649 | command queries assigned leases. | |
650 | ||
651 | - Added support for smartcards in charon by using the ENGINE API provided by | |
652 | OpenSSL, based on patches by Michael Roßberg. | |
653 | ||
654 | - The Padlock plugin supports the hardware RNG found on VIA CPUs to provide a | |
655 | reliable source of randomness. | |
656 | ||
73937bd8 MW |
657 | strongswan-4.2.9 |
658 | ---------------- | |
659 | ||
509e07c5 AS |
660 | - Flexible configuration of logging subsystem allowing to log to multiple |
661 | syslog facilities or to files using fine-grained log levels for each target. | |
73937bd8 MW |
662 | |
663 | - Load testing plugin to do stress testing of the IKEv2 daemon against self | |
664 | or another host. Found and fixed issues during tests in the multi-threaded | |
665 | use of the OpenSSL plugin. | |
666 | ||
667 | - Added profiling code to synchronization primitives to find bottlenecks if | |
7bdc931e | 668 | running on multiple cores. Found and fixed an issue where parts of the |
73937bd8 MW |
669 | Diffie-Hellman calculation acquired an exclusive lock. This greatly improves |
670 | parallelization to multiple cores. | |
671 | ||
509e07c5 AS |
672 | - updown script invocation has been separated into a plugin of its own to |
673 | further slim down the daemon core. | |
73937bd8 | 674 | |
509e07c5 | 675 | - Separated IKE_SA/CHILD_SA key derivation process into a closed system, |
7bdc931e | 676 | allowing future implementations to use a secured environment in e.g. kernel |
73937bd8 MW |
677 | memory or hardware. |
678 | ||
509e07c5 AS |
679 | - The kernel interface of charon has been modularized. XFRM NETLINK (default) |
680 | and PFKEY (--enable-kernel-pfkey) interface plugins for the native IPsec | |
681 | stack of the Linux 2.6 kernel as well as a PFKEY interface for the KLIPS | |
682 | IPsec stack (--enable-kernel-klips) are provided. | |
683 | ||
684 | - Basic Mobile IPv6 support has been introduced, securing Binding Update | |
685 | messages as well as tunneled traffic between Mobile Node and Home Agent. | |
686 | The installpolicy=no option allows peaceful cooperation with a dominant | |
687 | mip6d daemon and the new type=transport_proxy implements the special MIPv6 | |
688 | IPsec transport proxy mode where the IKEv2 daemon uses the Care-of-Address | |
f3bb1bd0 | 689 | but the IPsec SA is set up for the Home Address. |
7bdc931e | 690 | |
4dc0dce8 AS |
691 | - Implemented migration of Mobile IPv6 connections using the KMADDRESS |
692 | field contained in XFRM_MSG_MIGRATE messages sent by the mip6d daemon | |
693 | via the Linux 2.6.28 (or appropriately patched) kernel. | |

e39b271b AS |
696 | strongswan-4.2.8 |
697 | ---------------- | |
698 | ||
5dadb16e | 699 | - IKEv2 charon daemon supports authentication based on raw public keys |
e39b271b AS |
700 | stored in the SQL database backend. The ipsec listpubkeys command |
701 | lists the available raw public keys via the stroke interface. | |
702 | ||
4f0241e6 MW |
703 | - Several MOBIKE improvements: Detect changes in NAT mappings in DPD exchanges, |
704 | handle events if kernel detects NAT mapping changes in UDP-encapsulated | |
705 | ESP packets (requires kernel patch), reuse old addesses in MOBIKE updates as | |
706 | long as possible and other fixes. | |
707 | ||
5dadb16e AS |
708 | - Fixed a bug in addr_in_subnet() which caused insertion of wrong source |
709 | routes for destination subnets having netwmasks not being a multiple of 8 bits. | |
710 | Thanks go to Wolfgang Steudel, TU Ilmenau for reporting this bug. | |

713 | strongswan-4.2.7 |
714 | ---------------- | |
715 | ||
b37cda82 AS |
716 | - Fixed a Denial-of-Service vulnerability where an IKE_SA_INIT message with |
717 | a KE payload containing zeroes only can cause a crash of the IKEv2 charon | |
718 | daemon due to a NULL pointer returned by the mpz_export() function of the | |
719 | GNU Multiprecision Library (GMP). Thanks go to Mu Dynamics Research Labs | |
b6b90b68 | 720 | for making us aware of this problem. |
b37cda82 | 721 | |
b6b90b68 | 722 | - The new agent plugin provides a private key implementation on top of an |
e376d75f MW |
723 | ssh-agent. |
724 | ||
725 | - The NetworkManager plugin has been extended to support certificate client | |
b1f47854 | 726 | authentication using RSA keys loaded from a file or using ssh-agent. |
e376d75f MW |
727 | |
728 | - Daemon capability dropping has been ported to libcap and must be enabled | |
729 | explicitly --with-capabilities=libcap. Future version will support the | |
730 | newer libcap2 library. | |
731 | ||
b37cda82 AS |
732 | - ipsec listalgs lists the IKEv2 cryptografic algorithms registered with the |
733 | charon keying daemon. | |

609166f4 MW |
739 | - A NetworkManager plugin allows GUI-based configuration of road-warrior |
740 | clients in a simple way. It features X509 based gateway authentication | |
741 | and EAP client authentication, tunnel setup/teardown and storing passwords | |
742 | in the Gnome Keyring. | |
743 | ||
744 | - A new EAP-GTC plugin implements draft-sheffer-ikev2-gtc-00.txt and allows | |
745 | username/password authentication against any PAM service on the gateway. | |
b6b90b68 | 746 | The new EAP method interacts nicely with the NetworkManager plugin and allows |
609166f4 MW |
747 | client authentication against e.g. LDAP. |
748 | ||
749 | - Improved support for the EAP-Identity method. The new ipsec.conf eap_identity | |
750 | parameter defines an additional identity to pass to the server in EAP | |
751 | authentication. | |
752 | ||
9f9d6ece AS |
753 | - The "ipsec statusall" command now lists CA restrictions, EAP |
754 | authentication types and EAP identities. | |
755 | ||
756 | - Fixed two multithreading deadlocks occurring when starting up | |
757 | several hundred tunnels concurrently. | |
758 | ||
759 | - Fixed the --enable-integrity-test configure option which | |
760 | computes a SHA-1 checksum over the libstrongswan library. | |
761 | ||
762 | ||
174216c7 AS |
763 | strongswan-4.2.5 |
764 | ---------------- | |
765 | ||
b6b90b68 | 766 | - Consistent logging of IKE and CHILD SAs at the audit (AUD) level. |
8124e491 AS |
767 | |
768 | - Improved the performance of the SQL-based virtual IP address pool | |
769 | by introducing an additional addresses table. The leases table | |
770 | storing only history information has become optional and can be | |
771 | disabled by setting charon.plugins.sql.lease_history = no in | |
772 | strongswan.conf. | |
773 | ||
eb0cc338 | 774 | - The XFRM_STATE_AF_UNSPEC flag added to xfrm.h allows IPv4-over-IPv6 |
de5f70e7 | 775 | and IPv6-over-IPv4 tunnels with the 2.6.26 and later Linux kernels. |
eb0cc338 | 776 | |
174216c7 AS |
777 | - management of different virtual IP pools for different |
778 | network interfaces have become possible. | |
779 | ||
b6b90b68 | 780 | - fixed a bug which prevented the assignment of more than 256 |
174216c7 AS |
781 | virtual IP addresses from a pool managed by an sql database. |
782 | ||
8124e491 AS |
783 | - fixed a bug which did not delete own IPCOMP SAs in the kernel. |
784 | ||
b6b90b68 | 785 | |
179dd12c AS |
786 | strongswan-4.2.4 |
787 | ---------------- | |
788 | ||
9de95037 AS |
789 | - Added statistics functions to ipsec pool --status and ipsec pool --leases |
790 | and input validation checks to various ipsec pool commands. | |
179dd12c | 791 | |
73a8eed3 | 792 | - ipsec statusall now lists all loaded charon plugins and displays |
9de95037 | 793 | the negotiated IKEv2 cipher suite proposals. |
73a8eed3 AS |
794 | |
795 | - The openssl plugin supports the elliptic curve Diffie-Hellman groups | |
796 | 19, 20, 21, 25, and 26. | |
797 | ||
798 | - The openssl plugin supports ECDSA authentication using elliptic curve | |
799 | X.509 certificates. | |
800 | ||
801 | - Fixed a bug in stroke which caused multiple charon threads to close | |
802 | the file descriptors during packet transfers over the stroke socket. | |
b6b90b68 | 803 | |
e0bb4dbb AS |
804 | - ESP sequence numbers are now migrated in IPsec SA updates handled by |
805 | MOBIKE. Works only with Linux kernels >= 2.6.17. | |
806 | ||
179dd12c | 807 | |
83d9e870 AS |
808 | strongswan-4.2.3 |
809 | ---------------- | |
810 | ||
b6b90b68 | 811 | - Fixed the strongswan.conf path configuration problem that occurred when |
83d9e870 AS |
812 | --sysconfig was not set explicitly in ./configure. |
813 | ||
814 | - Fixed a number of minor bugs that where discovered during the 4th | |
815 | IKEv2 interoperability workshop in San Antonio, TX. | |
816 | ||
817 | ||
7f491111 MW |
818 | strongswan-4.2.2 |
819 | ---------------- | |
820 | ||
a57cd446 AS |
821 | - Plugins for libstrongswan and charon can optionally be loaded according |
822 | to a configuration in strongswan.conf. Most components provide a | |
7f491111 | 823 | "load = " option followed by a space separated list of plugins to load. |
a57cd446 AS |
824 | This allows e.g. the fallback from a hardware crypto accelerator to |
825 | to software-based crypto plugins. | |
7f491111 MW |
826 | |
827 | - Charons SQL plugin has been extended by a virtual IP address pool. | |
a57cd446 AS |
828 | Configurations with a rightsourceip=%poolname setting query a SQLite or |
829 | MySQL database for leases. The "ipsec pool" command helps in administrating | |
830 | the pool database. See ipsec pool --help for the available options | |
831 | ||
832 | - The Authenticated Encryption Algorithms AES-CCM-8/12/16 and AES-GCM-8/12/16 | |
b6b90b68 | 833 | for ESP are now supported starting with the Linux 2.6.25 kernel. The |
a57cd446 AS |
834 | syntax is e.g. esp=aes128ccm12 or esp=aes256gcm16. |
835 | ||
7f491111 | 836 | |
5c5d67d6 AS |
837 | strongswan-4.2.1 |
838 | ---------------- | |
839 | ||
c306dfb1 | 840 | - Support for "Hash and URL" encoded certificate payloads has been implemented |
b1f8fc0c TB |
841 | in the IKEv2 daemon charon. Using the "certuribase" option of a CA section |
842 | allows to assign a base URL to all certificates issued by the specified CA. | |
843 | The final URL is then built by concatenating that base and the hex encoded | |
844 | SHA1 hash of the DER encoded certificate. Note that this feature is disabled | |
845 | by default and must be enabled using the option "charon.hash_and_url". | |
5c5d67d6 | 846 | |
58caabf7 MW |
847 | - The IKEv2 daemon charon now supports the "uniqueids" option to close multiple |
848 | IKE_SAs with the same peer. The option value "keep" prefers existing | |
849 | connection setups over new ones, where the value "replace" replaces existing | |
850 | connections. | |
b6b90b68 | 851 | |
f3bb1bd0 | 852 | - The crypto factory in libstrongswan additionally supports random number |
58caabf7 | 853 | generators, plugins may provide other sources of randomness. The default |
c306dfb1 | 854 | plugin reads raw random data from /dev/(u)random. |
58caabf7 | 855 | |
b6b90b68 | 856 | - Extended the credential framework by a caching option to allow plugins |
58caabf7 | 857 | persistent caching of fetched credentials. The "cachecrl" option has been |
c306dfb1 | 858 | re-implemented. |
58caabf7 MW |
859 | |
860 | - The new trustchain verification introduced in 4.2.0 has been parallelized. | |
861 | Threads fetching CRL or OCSP information no longer block other threads. | |
5c5d67d6 | 862 | |
58caabf7 MW |
863 | - A new IKEv2 configuration attribute framework has been introduced allowing |
864 | plugins to provide virtual IP addresses, and in the future, other | |
865 | configuration attribute services (e.g. DNS/WINS servers). | |
5c5d67d6 | 866 | |
466abb49 | 867 | - The stroke plugin has been extended to provide virtual IP addresses from |
58caabf7 MW |
868 | a pool defined in ipsec.conf. The "rightsourceip" parameter now accepts |
869 | address pools in CIDR notation (e.g. 10.1.1.0/24). The parameter also accepts | |
870 | the value "%poolname", where "poolname" identifies a pool provided by a | |
466abb49 | 871 | separate plugin. |
58caabf7 | 872 | |
c306dfb1 | 873 | - Fixed compilation on uClibc and a couple of other minor bugs. |
58caabf7 | 874 | |
c306dfb1 | 875 | - Set DPD defaults in ipsec starter to dpd_delay=30s and dpd_timeout=150s. |
466abb49 AS |
876 | |
877 | - The IKEv1 pluto daemon now supports the ESP encryption algorithm CAMELLIA | |
c306dfb1 | 878 | with key lengths of 128, 192, and 256 bits, as well as the authentication |
466abb49 AS |
879 | algorithm AES_XCBC_MAC. Configuration example: esp=camellia192-aesxcbc. |
880 | ||
5c5d67d6 | 881 | |
a11ea97d AS |
882 | strongswan-4.2.0 |
883 | ---------------- | |
884 | ||
16f5dacd MW |
885 | - libstrongswan has been modularized to attach crypto algorithms, |
886 | credential implementations (keys, certificates) and fetchers dynamically | |
887 | through plugins. Existing code has been ported to plugins: | |
888 | - RSA/Diffie-Hellman implementation using the GNU Multi Precision library | |
889 | - X509 certificate system supporting CRLs, OCSP and attribute certificates | |
890 | - Multiple plugins providing crypto algorithms in software | |
891 | - CURL and OpenLDAP fetcher | |
a11ea97d | 892 | |
16f5dacd MW |
893 | - libstrongswan gained a relational database API which uses pluggable database |
894 | providers. Plugins for MySQL and SQLite are available. | |
895 | ||
896 | - The IKEv2 keying daemon charon is more extensible. Generic plugins may provide | |
897 | connection configuration, credentials and EAP methods or control the daemon. | |
898 | Existing code has been ported to plugins: | |
899 | - EAP-AKA, EAP-SIM, EAP-MD5 and EAP-Identity | |
900 | - stroke configuration, credential and control (compatible to pluto) | |
901 | - XML bases management protocol to control and query the daemon | |
902 | The following new plugins are available: | |
903 | - An experimental SQL configuration, credential and logging plugin on | |
904 | top of either MySQL or SQLite | |
905 | - A unit testing plugin to run tests at daemon startup | |
906 | ||
907 | - The authentication and credential framework in charon has been heavily | |
908 | refactored to support modular credential providers, proper | |
909 | CERTREQ/CERT payload exchanges and extensible authorization rules. | |
910 | ||
b6b90b68 | 911 | - The framework of strongSwan Manager has envolved to the web application |
16f5dacd MW |
912 | framework libfast (FastCGI Application Server w/ Templates) and is usable |
913 | by other applications. | |
b6b90b68 | 914 | |
a11ea97d | 915 | |
6859f760 AS |
916 | strongswan-4.1.11 |
917 | ----------------- | |
fb6d76cd | 918 | |
a561f74d AS |
919 | - IKE rekeying in NAT situations did not inherit the NAT conditions |
920 | to the rekeyed IKE_SA so that the UDP encapsulation was lost with | |
921 | the next CHILD_SA rekeying. | |
922 | ||
923 | - Wrong type definition of the next_payload variable in id_payload.c | |
b6b90b68 | 924 | caused an INVALID_SYNTAX error on PowerPC platforms. |
fb6d76cd | 925 | |
e6b50b3f AS |
926 | - Implemented IKEv2 EAP-SIM server and client test modules that use |
927 | triplets stored in a file. For details on the configuration see | |
928 | the scenario 'ikev2/rw-eap-sim-rsa'. | |
929 | ||
fb6d76cd | 930 | |
83e0d841 AS |
931 | strongswan-4.1.10 |
932 | ----------------- | |
933 | ||
934 | - Fixed error in the ordering of the certinfo_t records in the ocsp cache that | |
b6b90b68 | 935 | caused multiple entries of the same serial number to be created. |
83e0d841 | 936 | |
fdc7c943 MW |
937 | - Implementation of a simple EAP-MD5 module which provides CHAP |
938 | authentication. This may be interesting in conjunction with certificate | |
939 | based server authentication, as weak passwords can't be brute forced | |
940 | (in contradiction to traditional IKEv2 PSK). | |
941 | ||
942 | - A complete software based implementation of EAP-AKA, using algorithms | |
943 | specified in 3GPP2 (S.S0055). This implementation does not use an USIM, | |
944 | but reads the secrets from ipsec.secrets. Make sure to read eap_aka.h | |
945 | before using it. | |
946 | ||
947 | - Support for vendor specific EAP methods using Expanded EAP types. The | |
b6b90b68 | 948 | interface to EAP modules has been slightly changed, so make sure to |
fdc7c943 | 949 | check the changes if you're already rolling your own modules. |
83e0d841 | 950 | |
fb6d76cd | 951 | |
5076770c AS |
952 | strongswan-4.1.9 |
953 | ---------------- | |
954 | ||
800b3356 AS |
955 | - The default _updown script now dynamically inserts and removes ip6tables |
956 | firewall rules if leftfirewall=yes is set in IPv6 connections. New IPv6 | |
957 | net-net and roadwarrior (PSK/RSA) scenarios for both IKEv1 and IKEV2 were | |
958 | added. | |
5076770c | 959 | |
6f274c2a MW |
960 | - Implemented RFC4478 repeated authentication to force EAP/Virtual-IP clients |
961 | to reestablish an IKE_SA within a given timeframe. | |
962 | ||
963 | - strongSwan Manager supports configuration listing, initiation and termination | |
964 | of IKE and CHILD_SAs. | |
965 | ||
966 | - Fixes and improvements to multithreading code. | |
967 | ||
8b678ad4 | 968 | - IKEv2 plugins have been renamed to libcharon-* to avoid naming conflicts. |
b6b90b68 | 969 | Make sure to remove the old plugins in $libexecdir/ipsec, otherwise they get |
8b678ad4 | 970 | loaded twice. |
5076770c | 971 | |
83e0d841 | 972 | |
b82e8231 AS |
973 | strongswan-4.1.8 |
974 | ---------------- | |
975 | ||
5076770c | 976 | - Removed recursive pthread mutexes since uClibc doesn't support them. |
b82e8231 AS |
977 | |
978 | ||
a4a3632c AS |
979 | strongswan-4.1.7 |
980 | ---------------- | |
981 | ||
982 | - In NAT traversal situations and multiple queued Quick Modes, | |
983 | those pending connections inserted by auto=start after the | |
984 | port floating from 500 to 4500 were erronously deleted. | |
985 | ||
6e193274 | 986 | - Added a "forceencaps" connection parameter to enforce UDP encapsulation |
078b6008 | 987 | to surmount restrictive firewalls. NAT detection payloads are faked to |
6e193274 MW |
988 | simulate a NAT situation and trick the other peer into NAT mode (IKEv2 only). |
989 | ||
990 | - Preview of strongSwan Manager, a web based configuration and monitoring | |
991 | application. It uses a new XML control interface to query the IKEv2 daemon | |
64d24679 | 992 | (see http://wiki.strongswan.org/wiki/Manager). |
6e193274 MW |
993 | |
994 | - Experimental SQLite configuration backend which will provide the configuration | |
995 | interface for strongSwan Manager in future releases. | |
996 | ||
997 | - Further improvements to MOBIKE support. | |
998 | ||
a4a3632c | 999 | |
3dcf9dbd AS |
1000 | strongswan-4.1.6 |
1001 | ---------------- | |
1002 | ||
3eac4dfd AS |
1003 | - Since some third party IKEv2 implementations run into |
1004 | problems with strongSwan announcing MOBIKE capability per | |
1005 | default, MOBIKE can be disabled on a per-connection-basis | |
1006 | using the mobike=no option. Whereas mobike=no disables the | |
1007 | sending of the MOBIKE_SUPPORTED notification and the floating | |
1008 | to UDP port 4500 with the IKE_AUTH request even if no NAT | |
1009 | situation has been detected, strongSwan will still support | |
1010 | MOBIKE acting as a responder. | |
1011 | ||
1012 | - the default ipsec routing table plus its corresponding priority | |
1013 | used for inserting source routes has been changed from 100 to 220. | |
1014 | It can be configured using the --with-ipsec-routing-table and | |
b6b90b68 MW |
1015 | --with-ipsec-routing-table-prio options. |
1016 | ||
bdc0b55b AS |
1017 | - the --enable-integrity-test configure option tests the |
1018 | integrity of the libstrongswan crypto code during the charon | |
1019 | startup. | |
b6b90b68 | 1020 | |
3eac4dfd AS |
1021 | - the --disable-xauth-vid configure option disables the sending |
1022 | of the XAUTH vendor ID. This can be used as a workaround when | |
1023 | interoperating with some Windows VPN clients that get into | |
1024 | trouble upon reception of an XAUTH VID without eXtended | |
1025 | AUTHentication having been configured. | |
b6b90b68 | 1026 | |
f872f9d1 AS |
1027 | - ipsec stroke now supports the rereadsecrets, rereadaacerts, |
1028 | rereadacerts, and listacerts options. | |
3dcf9dbd AS |
1029 | |
1030 | ||
7ad634a2 AS |
1031 | strongswan-4.1.5 |
1032 | ---------------- | |
1033 | ||
1034 | - If a DNS lookup failure occurs when resolving right=%<FQDN> | |
1035 | or right=<FQDN> combined with rightallowany=yes then the | |
1036 | connection is not updated by ipsec starter thus preventing | |
1037 | the disruption of an active IPsec connection. Only if the DNS | |
1038 | lookup successfully returns with a changed IP address the | |
1039 | corresponding connection definition is updated. | |
1040 | ||
8f5b363c MW |
1041 | - Routes installed by the keying daemons are now in a separate |
1042 | routing table with the ID 100 to avoid conflicts with the main | |
1043 | table. Route lookup for IKEv2 traffic is done in userspace to ignore | |
1044 | routes installed for IPsec, as IKE traffic shouldn't get encapsulated. | |
1045 | ||
7ad634a2 | 1046 | |
e93c68ba AS |
1047 | strongswan-4.1.4 |
1048 | ---------------- | |
1049 | ||
1050 | - The pluto IKEv1 daemon now exhibits the same behaviour as its | |
1051 | IKEv2 companion charon by inserting an explicit route via the | |
1052 | _updown script only if a sourceip exists. This is admissible | |
1053 | since routing through the IPsec tunnel is handled automatically | |
b7af55ac AS |
1054 | by NETKEY's IPsec policies. As a consequence the left|rightnexthop |
1055 | parameter is not required any more. | |
078ce348 AS |
1056 | |
1057 | - The new IKEv1 parameter right|leftallowany parameters helps to handle | |
1058 | the case where both peers possess dynamic IP addresses that are | |
1059 | usually resolved using DynDNS or a similar service. The configuration | |
1060 | ||
1061 | right=peer.foo.bar | |
1062 | rightallowany=yes | |
1063 | ||
1064 | can be used by the initiator to start up a connection to a peer | |
1065 | by resolving peer.foo.bar into the currently allocated IP address. | |
1066 | Thanks to the rightallowany flag the connection behaves later on | |
1067 | as | |
1068 | ||
1069 | right=%any | |
1070 | ||
1071 | so that the peer can rekey the connection as an initiator when his | |
1fbdab85 AS |
1072 | IP address changes. An alternative notation is |
1073 | ||
1074 | right=%peer.foo.bar | |
1075 | ||
1076 | which will implicitly set rightallowany=yes. | |
1077 | ||
1078 | - ipsec starter now fails more gracefully in the presence of parsing | |
1079 | errors. Flawed ca and conn section are discarded and pluto is started | |
1080 | if non-fatal errors only were encountered. If right=%peer.foo.bar | |
1081 | cannot be resolved by DNS then right=%any will be used so that passive | |
1082 | connections as a responder are still possible. | |
078ce348 | 1083 | |
a0a0bdd7 AS |
1084 | - The new pkcs11initargs parameter that can be placed in the |
1085 | setup config section of /etc/ipsec.conf allows the definition | |
1086 | of an argument string that is used with the PKCS#11 C_Initialize() | |
1087 | function. This non-standard feature is required by the NSS softoken | |
1088 | library. This patch was contributed by Robert Varga. | |
b6b90b68 | 1089 | |
a0a0bdd7 AS |
1090 | - Fixed a bug in ipsec starter introduced by strongswan-2.8.5 |
1091 | which caused a segmentation fault in the presence of unknown | |
1092 | or misspelt keywords in ipsec.conf. This bug fix was contributed | |
1093 | by Robert Varga. | |
1094 | ||
e3606f2b MW |
1095 | - Partial support for MOBIKE in IKEv2. The initiator acts on interface/ |
1096 | address configuration changes and updates IKE and IPsec SAs dynamically. | |
e93c68ba | 1097 | |
06651827 | 1098 | |
a3354a69 AS |
1099 | strongswan-4.1.3 |
1100 | ---------------- | |
1101 | ||
b6b90b68 | 1102 | - IKEv2 peer configuration selection now can be based on a given |
35d4809c AS |
1103 | certification authority using the rightca= statement. |
1104 | ||
1105 | - IKEv2 authentication based on RSA signatures now can handle multiple | |
41e16cf4 AS |
1106 | certificates issued for a given peer ID. This allows a smooth transition |
1107 | in the case of a peer certificate renewal. | |
a3354a69 | 1108 | |
998ca0ea MW |
1109 | - IKEv2: Support for requesting a specific virtual IP using leftsourceip on the |
1110 | client and returning requested virtual IPs using rightsourceip=%config | |
1111 | on the server. If the server does not support configuration payloads, the | |
1112 | client enforces its leftsourceip parameter. | |
1113 | ||
1114 | - The ./configure options --with-uid/--with-gid allow pluto and charon | |
1115 | to drop their privileges to a minimum and change to an other UID/GID. This | |
1116 | improves the systems security, as a possible intruder may only get the | |
1117 | CAP_NET_ADMIN capability. | |
1118 | ||
b6b90b68 | 1119 | - Further modularization of charon: Pluggable control interface and |
998ca0ea MW |
1120 | configuration backend modules provide extensibility. The control interface |
1121 | for stroke is included, and further interfaces using DBUS (NetworkManager) | |
1122 | or XML are on the way. A backend for storing configurations in the daemon | |
b6b90b68 | 1123 | is provided and more advanced backends (using e.g. a database) are trivial |
998ca0ea | 1124 | to implement. |
a3354a69 | 1125 | |
f3bb1bd0 | 1126 | - Fixed a compilation failure in libfreeswan occurring with Linux kernel |
41e16cf4 AS |
1127 | headers > 2.6.17. |
1128 | ||
1129 | ||
8ea7b96f AS |
1130 | strongswan-4.1.2 |
1131 | ---------------- | |
1132 | ||
e23d98a7 | 1133 | - Support for an additional Diffie-Hellman exchange when creating/rekeying |
37fb0355 MW |
1134 | a CHILD_SA in IKEv2 (PFS). PFS is enabled when the proposal contains a |
1135 | DH group (e.g. "esp=aes128-sha1-modp1536"). Further, DH group negotiation | |
1136 | is implemented properly for rekeying. | |
1137 | ||
1138 | - Support for the AES-XCBC-96 MAC algorithm for IPsec SAs when using IKEv2 | |
1139 | (requires linux >= 2.6.20). It is enabled using e.g. "esp=aes256-aesxcbc". | |
1140 | ||
d931f465 MW |
1141 | - Working IPv4-in-IPv6 and IPv6-in-IPv4 tunnels for linux >= 2.6.21. |
1142 | ||
37fb0355 MW |
1143 | - Added support for EAP modules which do not establish an MSK. |
1144 | ||
dfbe2a0f | 1145 | - Removed the dependencies from the /usr/include/linux/ headers by |
9f78f957 | 1146 | including xfrm.h, ipsec.h, and pfkeyv2.h in the distribution. |
b6b90b68 | 1147 | |
9f78f957 AS |
1148 | - crlNumber is now listed by ipsec listcrls |
1149 | ||
8ea7b96f AS |
1150 | - The xauth_modules.verify_secret() function now passes the |
1151 | connection name. | |
1152 | ||
e23d98a7 | 1153 | |
ed284399 MW |
1154 | strongswan-4.1.1 |
1155 | ---------------- | |
1156 | ||
1157 | - Server side cookie support. If to may IKE_SAs are in CONNECTING state, | |
1158 | cookies are enabled and protect against DoS attacks with faked source | |
1159 | addresses. Number of IKE_SAs in CONNECTING state is also limited per | |
1160 | peer address to avoid resource exhaustion. IKE_SA_INIT messages are | |
1161 | compared to properly detect retransmissions and incoming retransmits are | |
1162 | detected even if the IKE_SA is blocked (e.g. doing OCSP fetches). | |
1163 | ||
db88e37d AS |
1164 | - The IKEv2 daemon charon now supports dynamic http- and ldap-based CRL |
1165 | fetching enabled by crlcheckinterval > 0 and caching fetched CRLs | |
1166 | enabled by cachecrls=yes. | |
1167 | ||
3b4f7d92 AS |
1168 | - Added the configuration options --enable-nat-transport which enables |
1169 | the potentially insecure NAT traversal for IPsec transport mode and | |
1170 | --disable-vendor-id which disables the sending of the strongSwan | |
1171 | vendor ID. | |
1172 | ||
1173 | - Fixed a long-standing bug in the pluto IKEv1 daemon which caused | |
1174 | a segmentation fault if a malformed payload was detected in the | |
1175 | IKE MR2 message and pluto tried to send an encrypted notification | |
1176 | message. | |
1177 | ||
46b9ff68 AS |
1178 | - Added the NATT_IETF_02_N Vendor ID in order to support IKEv1 connections |
1179 | with Windows 2003 Server which uses a wrong VID hash. | |
1180 | ||
3b4f7d92 | 1181 | |
34bbd0c3 | 1182 | strongswan-4.1.0 |
cd3958f8 AS |
1183 | ---------------- |
1184 | ||
1185 | - Support of SHA2_384 hash function for protecting IKEv1 | |
1186 | negotiations and support of SHA2 signatures in X.509 certificates. | |
1187 | ||
1188 | - Fixed a serious bug in the computation of the SHA2-512 HMAC | |
1189 | function. Introduced automatic self-test of all IKEv1 hash | |
1190 | and hmac functions during pluto startup. Failure of a self-test | |
1191 | currently issues a warning only but does not exit pluto [yet]. | |
1192 | ||
9b45443d MW |
1193 | - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2. |
1194 | ||
c5d0fbb6 | 1195 | - Full support of CA information sections. ipsec listcainfos |
b6b90b68 | 1196 | now shows all collected crlDistributionPoints and OCSP |
c5d0fbb6 AS |
1197 | accessLocations. |
1198 | ||
69ed04bf AS |
1199 | - Support of the Online Certificate Status Protocol (OCSP) for IKEv2. |
1200 | This feature requires the HTTP fetching capabilities of the libcurl | |
1201 | library which must be enabled by setting the --enable-http configure | |
1202 | option. | |
1203 | ||
9b45443d MW |
1204 | - Refactored core of the IKEv2 message processing code, allowing better |
1205 | code reuse and separation. | |
1206 | ||
1207 | - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration | |
1208 | payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted | |
1209 | by the requestor and installed in a resolv.conf file. | |
1210 | ||
1211 | - The IKEv2 daemon charon installs a route for each IPsec policy to use | |
1212 | the correct source address even if an application does not explicitly | |
1213 | specify it. | |
1214 | ||
1215 | - Integrated the EAP framework into charon which loads pluggable EAP library | |
1216 | modules. The ipsec.conf parameter authby=eap initiates EAP authentication | |
1217 | on the client side, while the "eap" parameter on the server side defines | |
1218 | the EAP method to use for client authentication. | |
1219 | A generic client side EAP-Identity module and an EAP-SIM authentication | |
1220 | module using a third party card reader implementation are included. | |
1221 | ||
1222 | - Added client side support for cookies. | |
1223 | ||
1224 | - Integrated the fixes done at the IKEv2 interoperability bakeoff, including | |
1225 | strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor | |
1226 | fixes to enhance interoperability with other implementations. | |

1229 | strongswan-4.0.7 |
1230 | ---------------- | |
1231 | ||
6fdf5f44 AS |
1232 | - strongSwan now interoperates with the NCP Secure Entry Client, |
1233 | the Shrew Soft VPN Client, and the Cisco VPN client, doing both | |
1234 | XAUTH and Mode Config. | |
1c266d7d AS |
1235 | |
1236 | - UNITY attributes are now recognized and UNITY_BANNER is set | |
1237 | to a default string. | |
1238 | ||
1239 | ||
2b4405a3 MW |
1240 | strongswan-4.0.6 |
1241 | ---------------- | |
1242 | ||
e38a15d4 AS |
1243 | - IKEv1: Support for extended authentication (XAUTH) in combination |
1244 | with ISAKMP Main Mode RSA or PSK authentication. Both client and | |
1245 | server side were implemented. Handling of user credentials can | |
1246 | be done by a run-time loadable XAUTH module. By default user | |
b6b90b68 MW |
1247 | credentials are stored in ipsec.secrets. |
1248 | ||
2b4405a3 MW |
1249 | - IKEv2: Support for reauthentication when rekeying |
1250 | ||
5903179b | 1251 | - IKEv2: Support for transport mode |
af87afed | 1252 | |
5903179b | 1253 | - fixed a lot of bugs related to byte order |
2b4405a3 | 1254 | |
5903179b | 1255 | - various other bugfixes |

0cd645d2 AS |
1258 | strongswan-4.0.5 |
1259 | ---------------- | |
1260 | ||
1261 | - IKEv1: Implementation of ModeConfig push mode via the new connection | |
1262 | keyword modeconfig=push allows interoperability with Cisco VPN gateways. | |
1263 | ||
1264 | - IKEv1: The command ipsec statusall now shows "DPD active" for all | |
1265 | ISAKMP SAs that are under active Dead Peer Detection control. | |
1266 | ||
1267 | - IKEv2: Charon's logging and debugging framework has been completely rewritten. | |
1268 | Instead of logger, special printf() functions are used to directly | |
1269 | print objects like hosts (%H) identifications (%D), certificates (%Q), | |
1270 | etc. The number of debugging levels have been reduced to: | |
03bf883d | 1271 | |
0cd645d2 | 1272 | 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private) |
03bf883d | 1273 | |
0cd645d2 AS |
1274 | The debugging levels can either be specified statically in ipsec.conf as |
1275 | ||
1276 | config setup | |
03bf883d | 1277 | charondebug="lib 1, cfg 3, net 2" |
0cd645d2 | 1278 | |
03bf883d | 1279 | or changed at runtime via stroke as |
0cd645d2 | 1280 | |
03bf883d | 1281 | ipsec stroke loglevel cfg 2 |
0cd645d2 AS |

48dc3934 MW |
1284 | strongswan-4.0.4 |
1285 | ---------------- | |
1286 | ||
1287 | - Implemented full support for IPv6-in-IPv6 tunnels. | |
1288 | ||
1289 | - Added configuration options for dead peer detection in IKEv2. dpd_action | |
1290 | types "clear", "hold" and "restart" are supported. The dpd_timeout | |
1291 | value is not used, as the normal retransmission policy applies to | |
1292 | detect dead peers. The dpd_delay parameter enables sending of empty | |
1293 | informational message to detect dead peers in case of inactivity. | |
1294 | ||
1295 | - Added support for preshared keys in IKEv2. PSK keys configured in | |
1296 | ipsec.secrets are loaded. The authby parameter specifies the authentication | |
1297 | method to authentificate ourself, the other peer may use PSK or RSA. | |
1298 | ||
1299 | - Changed retransmission policy to respect the keyingtries parameter. | |
1300 | ||
112ad7c3 AS |
1301 | - Added private key decryption. PEM keys encrypted with AES-128/192/256 |
1302 | or 3DES are supported. | |
48dc3934 MW |
1303 | |
1304 | - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to | |
1305 | encrypt IKE traffic. | |
1306 | ||
1307 | - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates | |
1308 | signed with such a hash algorithm. | |
1309 | ||
1310 | - Added initial support for updown scripts. The actions up-host/client and | |
1311 | down-host/client are executed. The leftfirewall=yes parameter | |
1312 | uses the default updown script to insert dynamic firewall rules, a custom | |
1313 | updown script may be specified with the leftupdown parameter. | |
1314 | ||
1315 | ||
a1310b6b MW |
1316 | strongswan-4.0.3 |
1317 | ---------------- | |
1318 | ||
1319 | - Added support for the auto=route ipsec.conf parameter and the | |
b6b90b68 MW |
1320 | ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and |
1321 | CHILD_SAs dynamically on demand when traffic is detected by the | |
a1310b6b MW |
1322 | kernel. |
1323 | ||
1324 | - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter. | |
1325 | As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only | |
1326 | new keys are generated using perfect forward secrecy. An optional flag | |
1327 | which enforces reauthentication will be implemented later. | |
1328 | ||
b425d998 AS |
1329 | - "sha" and "sha1" are now treated as synonyms in the ike= and esp= |
1330 | algorithm configuration statements. | |
1331 | ||
1332 | ||
bf4df11f AS |
1333 | strongswan-4.0.2 |
1334 | ---------------- | |
1335 | ||
623d3dcf AS |
1336 | - Full X.509 certificate trust chain verification has been implemented. |
1337 | End entity certificates can be exchanged via CERT payloads. The current | |
1338 | default is leftsendcert=always, since CERTREQ payloads are not supported | |
1339 | yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls. | |
efa40c11 | 1340 | |
b6b90b68 | 1341 | - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2 |
efa40c11 | 1342 | would offer more possibilities for traffic selection, but the Linux kernel |
b6b90b68 | 1343 | currently does not support it. That's why we stick with these simple |
efa40c11 MW |
1344 | ipsec.conf rules for now. |
1345 | ||
623d3dcf AS |
1346 | - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no |
1347 | IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear, | |
1348 | dpddelay=60s). | |
1349 | ||
efa40c11 MW |
1350 | - Initial NAT traversal support in IKEv2. Charon includes NAT detection |
1351 | notify payloads to detect NAT routers between the peers. It switches | |
1352 | to port 4500, uses UDP encapsulated ESP packets, handles peer address | |
1353 | changes gracefully and sends keep alive message periodically. | |
1354 | ||
b6b90b68 MW |
1355 | - Reimplemented IKE_SA state machine for charon, which allows simultaneous |
1356 | rekeying, more shared code, cleaner design, proper retransmission | |
efa40c11 MW |
1357 | and a more extensible code base. |
1358 | ||
cfd8b27f AS |
1359 | - The mixed PSK/RSA roadwarrior detection capability introduced by the |
1360 | strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal | |
1361 | payloads by the responder right before any defined IKE Main Mode state had | |
1362 | been established. Although any form of bad proposal syntax was being correctly | |
1363 | detected by the payload parser, the subsequent error handler didn't check | |
1364 | the state pointer before logging current state information, causing an | |
1365 | immediate crash of the pluto keying daemon due to a NULL pointer. | |
1366 | ||
bf4df11f | 1367 | |
7e81e975 MW |
1368 | strongswan-4.0.1 |
1369 | ---------------- | |
1370 | ||
b6b90b68 | 1371 | - Added algorithm selection to charon: New default algorithms for |
c15c3d4b MW |
1372 | ike=aes128-sha-modp2048, as both daemons support it. The default |
1373 | for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles | |
1374 | the ike/esp parameter the same way as pluto. As this syntax does | |
b6b90b68 | 1375 | not allow specification of a pseudo random function, the same |
c15c3d4b MW |
1376 | algorithm as for integrity is used (currently sha/md5). Supported |
1377 | algorithms for IKE: | |
1378 | Encryption: aes128, aes192, aes256 | |
1379 | Integrity/PRF: md5, sha (using hmac) | |
1380 | DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192 | |
1381 | and for ESP: | |
b6b90b68 | 1382 | Encryption: aes128, aes192, aes256, 3des, blowfish128, |
c15c3d4b MW |
1383 | blowfish192, blowfish256 |
1384 | Integrity: md5, sha1 | |
1385 | More IKE encryption algorithms will come after porting libcrypto into | |
b6b90b68 | 1386 | libstrongswan. |
f2c2d395 | 1387 | |
c15c3d4b MW |
1388 | - initial support for rekeying CHILD_SAs using IKEv2. Currently no |
1389 | perfect forward secrecy is used. The rekeying parameters rekey, | |
22ff6f57 | 1390 | rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported |
c15c3d4b MW |
1391 | when using IKEv2. WARNING: charon currently is unable to handle |
1392 | simultaneous rekeying. To avoid such a situation, use a large | |
1393 | rekeyfuzz, or even better, set rekey=no on one peer. | |
22ff6f57 | 1394 | |
7e81e975 MW |
1395 | - support for host2host, net2net, host2net (roadwarrior) tunnels |
1396 | using predefined RSA certificates (see uml scenarios for | |
1397 | configuration examples). | |
1398 | ||
f2c2d395 MW |
1399 | - new build environment featuring autotools. Features such |
1400 | as HTTP, LDAP and smartcard support may be enabled using | |
b6b90b68 | 1401 | the ./configure script. Changing install directories |
f2c2d395 MW |
1402 | is possible, too. See ./configure --help for more details. |
1403 | ||
22ff6f57 MW |
1404 | - better integration of charon with ipsec starter, which allows |
1405 | (almost) transparent operation with both daemons. charon | |
1406 | handles ipsec commands up, down, status, statusall, listall, | |
1407 | listcerts and allows proper load, reload and delete of connections | |
1408 | via ipsec starter. | |
1409 | ||
b425d998 | 1410 | |
9820c0e2 MW |
1411 | strongswan-4.0.0 |
1412 | ---------------- | |
1413 | ||
1414 | - initial support of the IKEv2 protocol. Connections in | |
b6b90b68 | 1415 | ipsec.conf designated by keyexchange=ikev2 are negotiated |
9820c0e2 MW |
1416 | by the new IKEv2 charon keying daemon whereas those marked |
1417 | by keyexchange=ikev1 or the default keyexchange=ike are | |
1418 | handled thy the IKEv1 pluto keying daemon. Currently only | |
1419 | a limited subset of functions are available with IKEv2 | |
1420 | (Default AES encryption, authentication based on locally | |
1421 | imported X.509 certificates, unencrypted private RSA keys | |
1422 | in PKCS#1 file format, limited functionality of the ipsec | |
1423 | status command). | |
1424 | ||
1425 | ||
997358a6 MW |
1426 | strongswan-2.7.0 |
1427 | ---------------- | |
1428 | ||
1429 | - the dynamic iptables rules from the _updown_x509 template | |
1430 | for KLIPS and the _updown_policy template for NETKEY have | |
1431 | been merged into the default _updown script. The existing | |
1432 | left|rightfirewall keyword causes the automatic insertion | |
1433 | and deletion of ACCEPT rules for tunneled traffic upon | |
1434 | the successful setup and teardown of an IPsec SA, respectively. | |
1435 | left|rightfirwall can be used with KLIPS under any Linux 2.4 | |
1436 | kernel or with NETKEY under a Linux kernel version >= 2.6.16 | |
f3bb1bd0 | 1437 | in conjunction with iptables >= 1.3.5. For NETKEY under a Linux |
997358a6 MW |
1438 | kernel version < 2.6.16 which does not support IPsec policy |
1439 | matching yet, please continue to use a copy of the _updown_espmark | |
1440 | template loaded via the left|rightupdown keyword. | |
1441 | ||
1442 | - a new left|righthostaccess keyword has been introduced which | |
1443 | can be used in conjunction with left|rightfirewall and the | |
1444 | default _updown script. By default leftfirewall=yes inserts | |
1445 | a bi-directional iptables FORWARD rule for a local client network | |
1446 | with a netmask different from 255.255.255.255 (single host). | |
1447 | This does not allow to access the VPN gateway host via its | |
1448 | internal network interface which is part of the client subnet | |
1449 | because an iptables INPUT and OUTPUT rule would be required. | |
1450 | lefthostaccess=yes will cause this additional ACCEPT rules to | |
b6b90b68 | 1451 | be inserted. |
997358a6 MW |
1452 | |
1453 | - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal | |
1454 | payload is preparsed in order to find out whether the roadwarrior | |
1455 | requests PSK or RSA so that a matching connection candidate can | |
1456 | be found. | |
1457 | ||
1458 | ||
1459 | strongswan-2.6.4 | |
1460 | ---------------- | |
1461 | ||
1462 | - the new _updown_policy template allows ipsec policy based | |
1463 | iptables firewall rules. Required are iptables version | |
1464 | >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes | |
b6b90b68 | 1465 | the _updown_espmark template, so that no INPUT mangle rules |
997358a6 MW |
1466 | are required any more. |
1467 | ||
1468 | - added support of DPD restart mode | |
1469 | ||
1470 | - ipsec starter now allows the use of wildcards in include | |
1471 | statements as e.g. in "include /etc/my_ipsec/*.conf". | |
1472 | Patch courtesy of Matthias Haas. | |
1473 | ||
1474 | - the Netscape OID 'employeeNumber' is now recognized and can be | |
1475 | used as a Relative Distinguished Name in certificates. | |
1476 | ||
1477 | ||
1478 | strongswan-2.6.3 | |
1479 | ---------------- | |
1480 | ||
b6b90b68 | 1481 | - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec |
997358a6 MW |
1482 | command and not of ipsec setup any more. |
1483 | ||
1484 | - ipsec starter now supports AH authentication in conjunction with | |
1485 | ESP encryption. AH authentication is configured in ipsec.conf | |
1486 | via the auth=ah parameter. | |
b6b90b68 | 1487 | |
997358a6 MW |
1488 | - The command ipsec scencrypt|scdecrypt <args> is now an alias for |
1489 | ipsec whack --scencrypt|scdecrypt <args>. | |
1490 | ||
1491 | - get_sa_info() now determines for the native netkey IPsec stack | |
1492 | the exact time of the last use of an active eroute. This information | |
1493 | is used by the Dead Peer Detection algorithm and is also displayed by | |
1494 | the ipsec status command. | |

1496 | |
1497 | strongswan-2.6.2 | |
1498 | ---------------- | |
1499 | ||
1500 | - running under the native Linux 2.6 IPsec stack, the function | |
1501 | get_sa_info() is called by ipsec auto --status to display the current | |
1502 | number of transmitted bytes per IPsec SA. | |
1503 | ||
1504 | - get_sa_info() is also used by the Dead Peer Detection process to detect | |
1505 | recent ESP activity. If ESP traffic was received from the peer within | |
1506 | the last dpd_delay interval then no R_Y_THERE notification must be sent. | |
1507 | ||
1508 | - strongSwan now supports the Relative Distinguished Name "unstructuredName" | |
1509 | in ID_DER_ASN1_DN identities. The following notations are possible: | |
1510 | ||
1511 | rightid="unstructuredName=John Doe" | |
1512 | rightid="UN=John Doe" | |
1513 | ||
1514 | - fixed a long-standing bug which caused PSK-based roadwarrior connections | |
1515 | to segfault in the function id.c:same_id() called by keys.c:get_secret() | |
1516 | if an FQDN, USER_FQDN, or Key ID was defined, as in the following example. | |
1517 | ||
1518 | conn rw | |
1519 | right=%any | |
1520 | rightid=@foo.bar | |
1521 | authby=secret | |
1522 | ||
1523 | - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall). | |
1524 | ||
1525 | - ipsec starter didn't set host_addr and client.addr ports in whack msg. | |
1526 | ||
1527 | - in order to guarantee backwards-compatibility with the script-based | |
1528 | auto function (e.g. auto --replace), the ipsec starter scripts stores | |
1529 | the defaultroute information in the temporary file /var/run/ipsec.info. | |
1530 | ||
1531 | - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH | |
1532 | Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config | |
1533 | servers. | |
1534 | ||
1535 | - the ipsec starter now also recognizes the parameters authby=never and | |
1536 | type=passthrough|pass|drop|reject. | |
1537 | ||
1538 | ||
1539 | strongswan-2.6.1 | |
1540 | ---------------- | |
1541 | ||
1542 | - ipsec starter now supports the also parameter which allows | |
1543 | a modular structure of the connection definitions. Thus | |
1544 | "ipsec start" is now ready to replace "ipsec setup". | |
1545 | ||
1546 | ||
1547 | strongswan-2.6.0 | |
1548 | ---------------- | |
1549 | ||
1550 | - Mathieu Lafon's popular ipsec starter tool has been added to the | |
1551 | strongSwan distribution. Many thanks go to Stephan Scholz from astaro | |
1552 | for his integration work. ipsec starter is a C program which is going | |
1553 | to replace the various shell and awk starter scripts (setup, _plutoload, | |
1554 | _plutostart, _realsetup, _startklips, _confread, and auto). Since | |
1555 | ipsec.conf is now parsed only once, the starting of multiple tunnels is | |
1556 | accelerated tremedously. | |
1557 | ||
1558 | - Added support of %defaultroute to the ipsec starter. If the IP address | |
b6b90b68 | 1559 | changes, a HUP signal to the ipsec starter will automatically |
997358a6 MW |
1560 | reload pluto's connections. |
1561 | ||
1562 | - moved most compile time configurations from pluto/Makefile to | |
1563 | Makefile.inc by defining the options USE_LIBCURL, USE_LDAP, | |
1564 | USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE. | |
1565 | ||
1566 | - removed the ipsec verify and ipsec newhostkey commands | |
1567 | ||
1568 | - fixed some 64-bit issues in formatted print statements | |
1569 | ||
1570 | - The scepclient functionality implementing the Simple Certificate | |
1571 | Enrollment Protocol (SCEP) is nearly complete but hasn't been | |
1572 | documented yet. | |
1573 | ||
1574 | ||
1575 | strongswan-2.5.7 | |
1576 | ---------------- | |
1577 | ||
1578 | - CA certicates are now automatically loaded from a smartcard | |
1579 | or USB crypto token and appear in the ipsec auto --listcacerts | |
1580 | listing. | |
1581 | ||
1582 | ||
1583 | strongswan-2.5.6 | |
1584 | ---------------- | |
1585 | ||
1586 | - when using "ipsec whack --scencrypt <data>" with a PKCS#11 | |
1587 | library that does not support the C_Encrypt() Cryptoki | |
1588 | function (e.g. OpenSC), the RSA encryption is done in | |
1589 | software using the public key fetched from the smartcard. | |
1590 | ||
b6b90b68 | 1591 | - The scepclient function now allows to define the |
997358a6 MW |
1592 | validity of a self-signed certificate using the --days, |
1593 | --startdate, and --enddate options. The default validity | |
1594 | has been changed from one year to five years. | |
1595 | ||
1596 | ||
1597 | strongswan-2.5.5 | |
1598 | ---------------- | |
1599 | ||
1600 | - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11 | |
1601 | interface to other applications for RSA encryption and decryption | |
1602 | via the whack interface. Notation: | |
1603 | ||
1604 | ipsec whack --scencrypt <data> | |
1605 | [--inbase 16|hex|64|base64|256|text|ascii] | |
1606 | [--outbase 16|hex|64|base64|256|text|ascii] | |
1607 | [--keyid <keyid>] | |
1608 | ||
1609 | ipsec whack --scdecrypt <data> | |
1610 | [--inbase 16|hex|64|base64|256|text|ascii] | |
1611 | [--outbase 16|hex|64|base64|256|text|ascii] | |
1612 | [--keyid <keyid>] | |
1613 | ||
b6b90b68 | 1614 | The default setting for inbase and outbase is hex. |
997358a6 MW |
1615 | |
1616 | The new proxy interface can be used for securing symmetric | |
1617 | encryption keys required by the cryptoloop or dm-crypt | |
1618 | disk encryption schemes, especially in the case when | |
1619 | pkcs11keepstate=yes causes pluto to lock the pkcs11 slot | |
1620 | permanently. | |
1621 | ||
1622 | - if the file /etc/ipsec.secrets is lacking during the startup of | |
1623 | pluto then the root-readable file /etc/ipsec.d/private/myKey.der | |
1624 | containing a 2048 bit RSA private key and a matching self-signed | |
1625 | certificate stored in the file /etc/ipsec.d/certs/selfCert.der | |
1626 | is automatically generated by calling the function | |
1627 | ||
1628 | ipsec scepclient --out pkcs1 --out cert-self | |
1629 | ||
1630 | scepclient was written by Jan Hutter and Martin Willi, students | |
1631 | at the University of Applied Sciences in Rapperswil, Switzerland. | |
1632 | ||
1633 | ||
1634 | strongswan-2.5.4 | |
1635 | ---------------- | |
1636 | ||
1637 | - the current extension of the PKCS#7 framework introduced | |
1638 | a parsing error in PKCS#7 wrapped X.509 certificates that are | |
1639 | e.g. transmitted by Windows XP when multi-level CAs are used. | |
1640 | the parsing syntax has been fixed. | |
1641 | ||
1642 | - added a patch by Gerald Richter which tolerates multiple occurrences | |
1643 | of the ipsec0 interface when using KLIPS. | |
1644 | ||
1645 | ||
1646 | strongswan-2.5.3 | |
1647 | ---------------- | |
1648 | ||
1649 | - with gawk-3.1.4 the word "default2 has become a protected | |
1650 | keyword for use in switch statements and cannot be used any | |
1651 | more in the strongSwan scripts. This problem has been | |
1652 | solved by renaming "default" to "defaults" and "setdefault" | |
1653 | in the scripts _confread and auto, respectively. | |
1654 | ||
1655 | - introduced the parameter leftsendcert with the values | |
1656 | ||
1657 | always|yes (the default, always send a cert) | |
1658 | ifasked (send the cert only upon a cert request) | |
1659 | never|no (never send a cert, used for raw RSA keys and | |
b6b90b68 | 1660 | self-signed certs) |
997358a6 MW |
1661 | |
1662 | - fixed the initialization of the ESP key length to a default of | |
1663 | 128 bits in the case that the peer does not send a key length | |
1664 | attribute for AES encryption. | |
1665 | ||
1666 | - applied Herbert Xu's uniqueIDs patch | |
1667 | ||
1668 | - applied Herbert Xu's CLOEXEC patches | |
1669 | ||
1670 | ||
1671 | strongswan-2.5.2 | |
1672 | ---------------- | |
1673 | ||
1674 | - CRLs can now be cached also in the case when the issuer's | |
1675 | certificate does not contain a subjectKeyIdentifier field. | |
1676 | In that case the subjectKeyIdentifier is computed by pluto as the | |
1677 | 160 bit SHA-1 hash of the issuer's public key in compliance | |
1678 | with section 4.2.1.2 of RFC 3280. | |
1679 | ||
1680 | - Fixed a bug introduced by strongswan-2.5.1 which eliminated | |
1681 | not only multiple Quick Modes of a given connection but also | |
1682 | multiple connections between two security gateways. | |
1683 | ||
1684 | ||
1685 | strongswan-2.5.1 | |
1686 | ---------------- | |
1687 | ||
1688 | - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute | |
1689 | installed either by setting auto=route in ipsec.conf or by | |
1690 | a connection put into hold, generates an XFRM_AQUIRE event | |
1691 | for each packet that wants to use the not-yet exisiting | |
1692 | tunnel. Up to now each XFRM_AQUIRE event led to an entry in | |
1693 | the Quick Mode queue, causing multiple IPsec SA to be | |
1694 | established in rapid succession. Starting with strongswan-2.5.1 | |
1695 | only a single IPsec SA is established per host-pair connection. | |
1696 | ||
1697 | - Right after loading the PKCS#11 module, all smartcard slots are | |
1698 | searched for certificates. The result can be viewed using | |
1699 | the command | |
1700 | ||
1701 | ipsec auto --listcards | |
1702 | ||
1703 | The certificate objects found in the slots are numbered | |
1704 | starting with #1, #2, etc. This position number can be used to address | |
1705 | certificates (leftcert=%smartcard) and keys (: PIN %smartcard) | |
1706 | in ipsec.conf and ipsec.secrets, respectively: | |
1707 | ||
1708 | %smartcard (selects object #1) | |
1709 | %smartcard#1 (selects object #1) | |
1710 | %smartcard#3 (selects object #3) | |
1711 | ||
1712 | As an alternative the existing retrieval scheme can be used: | |
1713 | ||
1714 | %smartcard:45 (selects object with id=45) | |
1715 | %smartcard0 (selects first object in slot 0) | |
1716 | %smartcard4:45 (selects object in slot 4 with id=45) | |
1717 | ||
1718 | - Depending on the settings of CKA_SIGN and CKA_DECRYPT | |
1719 | private key flags either C_Sign() or C_Decrypt() is used | |
1720 | to generate a signature. | |
1721 | ||
1722 | - The output buffer length parameter siglen in C_Sign() | |
1723 | is now initialized to the actual size of the output | |
1724 | buffer prior to the function call. This fixes the | |
1725 | CKR_BUFFER_TOO_SMALL error that could occur when using | |
1726 | the OpenSC PKCS#11 module. | |
1727 | ||
1728 | - Changed the initialization of the PKCS#11 CK_MECHANISM in | |
1729 | C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }. | |
1730 | ||
1731 | - Refactored the RSA public/private key code and transferred it | |
1732 | from keys.c to the new pkcs1.c file as a preparatory step | |
1733 | towards the release of the SCEP client. | |
1734 | ||
1735 | ||
1736 | strongswan-2.5.0 | |
1737 | ---------------- | |
1738 | ||
1739 | - The loading of a PKCS#11 smartcard library module during | |
1740 | runtime does not require OpenSC library functions any more | |
1741 | because the corresponding code has been integrated into | |
1742 | smartcard.c. Also the RSAREF pkcs11 header files have been | |
1743 | included in a newly created pluto/rsaref directory so that | |
1744 | no external include path has to be defined any longer. | |
1745 | ||
1746 | - A long-awaited feature has been implemented at last: | |
1747 | The local caching of CRLs fetched via HTTP or LDAP, activated | |
1748 | by the parameter cachecrls=yes in the config setup section | |
1749 | of ipsec.conf. The dynamically fetched CRLs are stored under | |
1750 | a unique file name containing the issuer's subjectKeyID | |
1751 | in /etc/ipsec.d/crls. | |
b6b90b68 | 1752 | |
997358a6 MW |
1753 | - Applied a one-line patch courtesy of Michael Richardson |
1754 | from the Openswan project which fixes the kernel-oops | |
1755 | in KLIPS when an snmp daemon is running on the same box. | |
1756 | ||
1757 | ||
1758 | strongswan-2.4.4 | |
1759 | ---------------- | |
1760 | ||
1761 | - Eliminated null length CRL distribution point strings. | |
1762 | ||
1763 | - Fixed a trust path evaluation bug introduced with 2.4.3 | |
1764 | ||
1765 | ||
1766 | strongswan-2.4.3 | |
1767 | ---------------- | |
1768 | ||
1769 | - Improved the joint OCSP / CRL revocation policy. | |
1770 | OCSP responses have precedence over CRL entries. | |
1771 | ||
1772 | - Introduced support of CRLv2 reason codes. | |
1773 | ||
1774 | - Fixed a bug with key-pad equipped readers which caused | |
1775 | pluto to prompt for the pin via the console when the first | |
1776 | occasion to enter the pin via the key-pad was missed. | |
1777 | ||
1778 | - When pluto is built with LDAP_V3 enabled, the library | |
1779 | liblber required by newer versions of openldap is now | |
1780 | included. | |
1781 | ||
1782 | ||
1783 | strongswan-2.4.2 | |
1784 | ---------------- | |
1785 | ||
1786 | - Added the _updown_espmark template which requires all | |
1787 | incoming ESP traffic to be marked with a default mark | |
1788 | value of 50. | |
b6b90b68 | 1789 | |
997358a6 MW |
1790 | - Introduced the pkcs11keepstate parameter in the config setup |
1791 | section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11 | |
b6b90b68 | 1792 | session and login states are kept as long as possible during |
997358a6 MW |
1793 | the lifetime of pluto. This means that a PIN entry via a key |
1794 | pad has to be done only once. | |
1795 | ||
1796 | - Introduced the pkcs11module parameter in the config setup | |
1797 | section of ipsec.conf which specifies the PKCS#11 module | |
1798 | to be used with smart cards. Example: | |
b6b90b68 | 1799 | |
997358a6 | 1800 | pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo |
b6b90b68 | 1801 | |
997358a6 MW |
1802 | - Added support of smartcard readers equipped with a PIN pad. |
1803 | ||
1804 | - Added patch by Jay Pfeifer which detects when netkey | |
1805 | modules have been statically built into the Linux 2.6 kernel. | |
1806 | ||
1807 | - Added two patches by Herbert Xu. The first uses ip xfrm | |
1808 | instead of setkey to flush the IPsec policy database. The | |
1809 | second sets the optional flag in inbound IPComp SAs only. | |
b6b90b68 | 1810 | |
997358a6 MW |
1811 | - Applied Ulrich Weber's patch which fixes an interoperability |
1812 | problem between native IPsec and KLIPS systems caused by | |
1813 | setting the replay window to 32 instead of 0 for ipcomp. | |
1814 | ||
1815 | ||
1816 | strongswan-2.4.1 | |
1817 | ---------------- | |
1818 | ||
1819 | - Fixed a bug which caused an unwanted Mode Config request | |
1820 | to be initiated in the case where "right" was used to denote | |
1821 | the local side in ipsec.conf and "left" the remote side, | |
1822 | contrary to the recommendation that "right" be remote and | |
1823 | "left" be"local". | |
1824 | ||
1825 | ||
1826 | strongswan-2.4.0a | |
1827 | ----------------- | |
1828 | ||
1829 | - updated Vendor ID to strongSwan-2.4.0 | |
1830 | ||
1831 | - updated copyright statement to include David Buechi and | |
1832 | Michael Meier | |
b6b90b68 MW |
1833 | |
1834 | ||
997358a6 MW |
1835 | strongswan-2.4.0 |
1836 | ---------------- | |
1837 | ||
1838 | - strongSwan now communicates with attached smartcards and | |
1839 | USB crypto tokens via the standardized PKCS #11 interface. | |
1840 | By default the OpenSC library from www.opensc.org is used | |
1841 | but any other PKCS#11 library could be dynamically linked. | |
1842 | strongSwan's PKCS#11 API was implemented by David Buechi | |
1843 | and Michael Meier, both graduates of the Zurich University | |
1844 | of Applied Sciences in Winterthur, Switzerland. | |
1845 | ||
1846 | - When a %trap eroute is triggered by an outgoing IP packet | |
1847 | then the native IPsec stack of the Linux 2.6 kernel [often/ | |
1848 | always?] returns an XFRM_ACQUIRE message with an undefined | |
1849 | protocol family field and the connection setup fails. | |
1850 | As a workaround IPv4 (AF_INET) is now assumed. | |
b6b90b68 MW |
1851 | |
1852 | - the results of the UML test scenarios are now enhanced | |
997358a6 | 1853 | with block diagrams of the virtual network topology used |
b6b90b68 | 1854 | in a particular test. |
997358a6 MW |
1855 | |
1856 | ||
1857 | strongswan-2.3.2 | |
1858 | ---------------- | |
1859 | ||
1860 | - fixed IV used to decrypt informational messages. | |
1861 | This bug was introduced with Mode Config functionality. | |
b6b90b68 | 1862 | |
997358a6 MW |
1863 | - fixed NCP Vendor ID. |
1864 | ||
1865 | - undid one of Ulrich Weber's maximum udp size patches | |
1866 | because it caused a segmentation fault with NAT-ed | |
1867 | Delete SA messages. | |
b6b90b68 | 1868 | |
997358a6 MW |
1869 | - added UML scenarios wildcards and attr-cert which |
1870 | demonstrate the implementation of IPsec policies based | |
1871 | on wildcard parameters contained in Distinguished Names and | |
1872 | on X.509 attribute certificates, respectively. | |
1873 | ||
1874 | ||
1875 | strongswan-2.3.1 | |
1876 | ---------------- | |
1877 | ||
1878 | - Added basic Mode Config functionality | |
1879 | ||
1880 | - Added Mathieu Lafon's patch which upgrades the status of | |
1881 | the NAT-Traversal implementation to RFC 3947. | |
b6b90b68 | 1882 | |
997358a6 MW |
1883 | - The _startklips script now also loads the xfrm4_tunnel |
1884 | module. | |
b6b90b68 | 1885 | |
997358a6 MW |
1886 | - Added Ulrich Weber's netlink replay window size and |
1887 | maximum udp size patches. | |
1888 | ||
1889 | - UML testing now uses the Linux 2.6.10 UML kernel by default. | |
b6b90b68 | 1890 | |
997358a6 MW |
1891 | |
1892 | strongswan-2.3.0 | |
1893 | ---------------- | |
1894 | ||
1895 | - Eric Marchionni and Patrik Rayo, both recent graduates from | |
1896 | the Zuercher Hochschule Winterthur in Switzerland, created a | |
1897 | User-Mode-Linux test setup for strongSwan. For more details | |
1898 | please read the INSTALL and README documents in the testing | |
1899 | subdirectory. | |
1900 | ||
1901 | - Full support of group attributes based on X.509 attribute | |
b6b90b68 | 1902 | certificates. Attribute certificates can be generated |
997358a6 | 1903 | using the openac facility. For more details see |
b6b90b68 | 1904 | |
997358a6 | 1905 | man ipsec_openac. |
b6b90b68 | 1906 | |
997358a6 MW |
1907 | The group attributes can be used in connection definitions |
1908 | in order to give IPsec access to specific user groups. | |
1909 | This is done with the new parameter left|rightgroups as in | |
b6b90b68 | 1910 | |
997358a6 MW |
1911 | rightgroups="Research, Sales" |
1912 | ||
1913 | giving access to users possessing the group attributes | |
1914 | Research or Sales, only. | |
1915 | ||
1916 | - In Quick Mode clients with subnet mask /32 are now | |
b6b90b68 | 1917 | coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should |
997358a6 MW |
1918 | fix rekeying problems with the SafeNet/SoftRemote and NCP |
1919 | Secure Entry Clients. | |
1920 | ||
1921 | - Changed the defaults of the ikelifetime and keylife parameters | |
1922 | to 3h and 1h, respectively. The maximum allowable values are | |
1923 | now both set to 24 h. | |
1924 | ||
1925 | - Suppressed notification wars between two IPsec peers that | |
1926 | could e.g. be triggered by incorrect ISAKMP encryption. | |
1927 | ||
1928 | - Public RSA keys can now have identical IDs if either the | |
1929 | issuing CA or the serial number is different. The serial | |
1930 | number of a certificate is now shown by the command | |

1932 | ipsec auto --listpubkeys |
1933 | ||
1934 | ||
1935 | strongswan-2.2.2 | |
1936 | ---------------- | |
1937 | ||
1938 | - Added Tuomo Soini's sourceip feature which allows a strongSwan | |
1939 | roadwarrior to use a fixed Virtual IP (see README section 2.6) | |
1940 | and reduces the well-known four tunnel case on VPN gateways to | |
1941 | a single tunnel definition (see README section 2.4). | |
1942 | ||
f3bb1bd0 | 1943 | - Fixed a bug occurring with NAT-Traversal enabled when the responder |
997358a6 MW |
1944 | suddenly turns initiator and the initiator cannot find a matching |
1945 | connection because of the floated IKE port 4500. | |
b6b90b68 | 1946 | |
997358a6 MW |
1947 | - Removed misleading ipsec verify command from barf. |
1948 | ||
1949 | - Running under the native IP stack, ipsec --version now shows | |
1950 | the Linux kernel version (courtesy to the Openswan project). | |

1952 | ||
1953 | strongswan-2.2.1 | |
1954 | ---------------- | |
1955 | ||
1956 | - Introduced the ipsec auto --listalgs monitoring command which lists | |
1957 | all currently registered IKE and ESP algorithms. | |
1958 | ||
f3bb1bd0 | 1959 | - Fixed a bug in the ESP algorithm selection occurring when the strict flag |
997358a6 | 1960 | is set and the first proposed transform does not match. |
b6b90b68 | 1961 | |
997358a6 | 1962 | - Fixed another deadlock in the use of the lock_certs_and_keys() mutex, |
f3bb1bd0 | 1963 | occurring when a smartcard is present. |
997358a6 MW |
1964 | |
1965 | - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event. | |
b6b90b68 | 1966 | |
997358a6 MW |
1967 | - Fixed the printing of the notification names (null) |
1968 | ||
1969 | - Applied another of Herbert Xu's Netlink patches. | |
1970 | ||
1971 | ||
1972 | strongswan-2.2.0 | |
1973 | ---------------- | |
1974 | ||
1975 | - Support of Dead Peer Detection. The connection parameter | |
1976 | ||
1977 | dpdaction=clear|hold | |
b6b90b68 | 1978 | |
997358a6 MW |
1979 | activates DPD for the given connection. |
1980 | ||
1981 | - The default Opportunistic Encryption (OE) policy groups are not | |
1982 | automatically included anymore. Those wishing to activate OE can include | |
1983 | the policy group with the following statement in ipsec.conf: | |
b6b90b68 | 1984 | |
997358a6 | 1985 | include /etc/ipsec.d/examples/oe.conf |
b6b90b68 | 1986 | |
997358a6 MW |
1987 | The default for [right|left]rsasigkey is now set to %cert. |
1988 | ||
1989 | - strongSwan now has a Vendor ID of its own which can be activated | |
1990 | using the compile option VENDORID | |
1991 | ||
1992 | - Applied Herbert Xu's patch which sets the compression algorithm correctly. | |
1993 | ||
1994 | - Applied Herbert Xu's patch fixing an ESPINUDP problem | |
1995 | ||
1996 | - Applied Herbert Xu's patch setting source/destination port numbers. | |
1997 | ||

2006 | |
2007 | strongswan-2.1.5 | |
2008 | ---------------- | |
2009 | ||
2010 | - Thomas Walpuski made me aware of a potential DoS attack via | |
2011 | a PKCS#7-wrapped certificate bundle which could overwrite valid CA | |
2012 | certificates in Pluto's authority certificate store. This vulnerability | |
2013 | was fixed by establishing trust in CA candidate certificates up to a | |
2014 | trusted root CA prior to insertion into Pluto's chained list. | |
2015 | ||
2016 | - replaced the --assign option by the -v option in the auto awk script | |
2017 | in order to make it run with mawk under debian/woody. | |
2018 | ||
2019 | ||
2020 | strongswan-2.1.4 | |
2021 | ---------------- | |
2022 | ||
2023 | - Split of the status information between ipsec auto --status (concise) | |
2024 | and ipsec auto --statusall (verbose). Both commands can be used with | |
2025 | an optional connection selector: | |
2026 | ||
2027 | ipsec auto --status[all] <connection_name> | |
2028 | ||
2029 | - Added the description of X.509 related features to the ipsec_auto(8) | |
2030 | man page. | |
2031 | ||
2032 | - Hardened the ASN.1 parser in debug mode, especially the printing | |
2033 | of malformed distinguished names. | |
2034 | ||
2035 | - The size of an RSA public key received in a certificate is now restricted to | |
2036 | ||
2037 | 512 bits <= modulus length <= 8192 bits. | |
2038 | ||
2039 | - Fixed the debug mode enumeration. | |
2040 | ||
2041 | ||
2042 | strongswan-2.1.3 | |
2043 | ---------------- | |
2044 | ||
2045 | - Fixed another PKCS#7 vulnerability which could lead to an | |
2046 | endless loop while following the X.509 trust chain. | |
b6b90b68 | 2047 | |
997358a6 MW |
2048 | |
2049 | strongswan-2.1.2 | |
2050 | ---------------- | |
2051 | ||
2052 | - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski | |
2053 | that accepted end certificates having identical issuer and subject | |
2054 | distinguished names in a multi-tier X.509 trust chain. | |
b6b90b68 | 2055 | |
997358a6 MW |
2056 | |
2057 | strongswan-2.1.1 | |
2058 | ---------------- | |
2059 | ||
2060 | - Removed all remaining references to ipsec_netlink.h in KLIPS. | |
2061 | ||
2062 | ||
2063 | strongswan-2.1.0 | |
2064 | ---------------- | |
2065 | ||
2066 | - The new "ca" section allows to define the following parameters: | |
2067 | ||
2068 | ca kool | |
2069 | cacert=koolCA.pem # cacert of kool CA | |
2070 | ocspuri=http://ocsp.kool.net:8001 # ocsp server | |
2071 | ldapserver=ldap.kool.net # default ldap server | |
2072 | crluri=http://www.kool.net/kool.crl # crl distribution point | |
2073 | crluri2="ldap:///O=Kool, C= .." # crl distribution point #2 | |
2074 | auto=add # add, ignore | |
b6b90b68 | 2075 | |
997358a6 | 2076 | The ca definitions can be monitored via the command |
b6b90b68 | 2077 | |
997358a6 MW |
2078 | ipsec auto --listcainfos |
2079 | ||
2080 | - Fixed cosmetic corruption of /proc filesystem by integrating | |
2081 | D. Hugh Redelmeier's freeswan-2.06 kernel fixes. | |
2082 | ||
2083 | ||
2084 | strongswan-2.0.2 | |
2085 | ---------------- | |
2086 | ||
2087 | - Added support for the 818043 NAT-Traversal update of Microsoft's | |
2088 | Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode. | |
b6b90b68 MW |
2089 | |
2090 | - A symbolic link to libcrypto is now added in the kernel sources | |
997358a6 | 2091 | during kernel compilation |
b6b90b68 | 2092 | |
997358a6 MW |
2093 | - Fixed a couple of 64 bit issues (mostly casts to int). |
2094 | Thanks to Ken Bantoft who checked my sources on a 64 bit platform. | |
2095 | ||
2096 | - Replaced s[n]printf() statements in the kernel by ipsec_snprintf(). | |
2097 | Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro | |
2098 | of the FreeS/WAN team who solved this problem with the 2.4.25 kernel. | |
2099 | ||
2100 | ||
2101 | strongswan-2.0.1 | |
2102 | ---------------- | |
2103 | ||
2104 | - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName | |
2105 | certificate extension which contains no generalName item) can cause | |
2106 | a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has | |
2107 | been hardened to make it more robust against malformed ASN.1 objects. | |
2108 | ||
2109 | - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native | |
2110 | Linux 2.6 IPsec stack. | |
