1 | strongswan-5.5.0 |
2 | ---------------- | |
3 | ||
4 | - The new libtpmtss library offers support for both TPM 1.2 and TPM 2.0 | |
5 | Trusted Platform Modules. This allows the Attestation IMC/IMV pair to | |
6 | do TPM 2.0 based attestation. | |
7 | ||
b977ef8e TB |
8 | - The behavior during IKEv2 exchange collisions has been improved/fixed in |
9 | several corner cases and support for TEMPORARY_FAILURE and CHILD_SA_NOT_FOUND | |
10 | notifies, as defined by RFC 7296, has been added. | |
8fafbffd | 11 | |
b977ef8e TB |
12 | - IPsec policy priorities can be set manually (e.g. for high-priority drop |
13 | policies) and outbound policies may be restricted to a network interface. | |
14 | ||
15 | - The scheme for the automatically calculated default priorities has been | |
16 | changed and now also considers port masks, which were added with 5.4.0. | |
17 | ||
18 | - FWD policies are now installed in both directions in regards to the traffic | |
19 | selectors. Because such "outbound" FWD policies could conflict with "inbound" | |
20 | FWD policies of other SAs they are installed with a lower priority and don't | |
21 | have a reqid set, which allows kernel plugins to distinguish between the two | |
22 | and prefer those with a reqid. | |
23 | ||
24 | - For outbound IPsec SAs no replay window is configured anymore. | |
25 | ||
26 | - Enhanced the functionality of the swanctl --list-conns command by listing | |
27 | IKE_SA and CHILD_SA reauthentication and rekeying settings, and EAP/XAuth | |
28 | identities and EAP types. | |
29 | ||
30 | - DNS servers installed by the resolve plugin are now refcounted, which should | |
31 | fix its use with make-before-break reauthentication. Any output written to | |
32 | stderr/stdout by resolvconf is now logged. | |
33 | ||
34 | - The methods in the kernel interfaces have been changed to take structs instead | |
35 | of long lists of arguments. Similarly the constructors for peer_cfg_t and | |
36 | child_cfg_t now take structs. | |

40 | ---------------- | |
41 | ||
6fc68343 TB |
42 | - Support for IKEv2 redirection (RFC 5685) has been added. Plugins may |
43 | implement the redirect_provider_t interface to decide if and when to redirect | |
44 | connecting clients. It is also possible to redirect established IKE_SAs based | |
45 | on different selectors via VICI/swanctl. Unless disabled in strongswan.conf | |
46 | the charon daemon will follow redirect requests received from servers. | |
47 | ||
c171afea TB |
48 | - The ike: prefix enables the explicit configuration of signature scheme |
49 | constraints against IKEv2 authentication in rightauth, which allows the use | |
50 | of different signature schemes for trustchain verification and authentication. | |
51 | ||
b4337c5b TB |
52 | - The initiator of an IKEv2 make-before-break reauthentication now suspends |
53 | online certificate revocation checks (OCSP, CRLs) until the new IKE_SA and all | |
54 | CHILD_SAs are established. This is required if the checks are done over the | |
55 | CHILD_SA established with the new IKE_SA. This is not possible until the | |
56 | initiator installs this SA and that only happens after the authentication is | |
57 | completed successfully. So we suspend the checks during the reauthentication | |
58 | and do them afterwards, if they fail the IKE_SA is closed. This change has no | |
59 | effect on the behavior during the authentication of the initial IKE_SA. | |
60 | ||
b5eed58a AS |
61 | - For the vici plugin a Vici:Session Perl CPAN module has been added to allow |
62 | Perl applications to control and/or monitor the IKE daemon using the VICI | |
63 | interface, similar to the existing Python egg or Ruby gem. | |
64 | ||
5c25780c AS |
65 | - Traffic selectors with port ranges can now be configured in the Linux kernel: |
66 | e.g. remote_ts = 10.1.0.0/16[tcp/20-23] local_ts = dynamic[tcp/32768-65535]. | |
67 | The port range must map to a port mask, though since the kernel does not | |
68 | support arbitrary ranges. | |
69 | ||
bebccf98 AS |
70 | - The vici plugin allows the configuration of IPv4 and IPv6 address ranges |
71 | in local and remote traffic selectors. Since both the Linux kernel and | |
72 | iptables cannot handle arbitrary ranges, address ranges are mapped to the next | |
73 | larger CIDR subnet by the kernel-netlink and updown plugins, respectively. | |
74 | ||
75 | - Implemented IKEv1 IPv4/IPv6 address subnet and range identities that can be | |
76 | used as owners of shared secrets. | |

79 | strongswan-5.3.5 |
80 | ---------------- | |
81 | ||
82 | - Properly handle potential EINTR errors in sigwaitinfo(2) calls that replaced | |
83 | sigwait(3) calls with 5.3.4. | |
84 | ||
85 | - RADIUS retransmission timeouts are now configurable, courtesy of Thom Troy. | |

6590298d AS |
88 | strongswan-5.3.4 |
89 | ---------------- | |
90 | ||
453e204a TB |
91 | - Fixed an authentication bypass vulnerability in the eap-mschapv2 plugin that |
92 | was caused by insufficient verification of the internal state when handling | |
93 | MSCHAPv2 Success messages received by the client. | |
94 | This vulnerability has been registered as CVE-2015-8023. | |
95 | ||
6590298d AS |
96 | - The sha3 plugin implements the SHA3 Keccak-F1600 hash algorithm family. |
97 | Within the strongSwan framework SHA3 is currently used for BLISS signatures | |
98 | only because the OIDs for other signature algorithms haven't been defined | |
99 | yet. Also the use of SHA3 for IKEv2 has not been standardized yet. | |
100 | ||
101 | ||
63d37038 AS |
102 | strongswan-5.3.3 |
103 | ---------------- | |
104 | ||
18e0d66b TB |
105 | - Added support for the ChaCha20/Poly1305 AEAD cipher specified in RFC 7539 and |
106 | RFC 7634 using the chacha20poly1305 ike/esp proposal keyword. The new chapoly | |
107 | plugin implements the cipher, if possible SSE-accelerated on x86/x64 | |
108 | architectures. It is usable both in IKEv2 and the strongSwan libipsec ESP | |
109 | backend. On Linux 4.2 or newer the kernel-netlink plugin can configure the | |
110 | cipher for ESP SAs. | |
39660798 | 111 | |
63d37038 | 112 | - The vici interface now supports the configuration of auxiliary certification |
18e0d66b TB |
113 | authority information as CRL and OCSP URIs. |
114 | ||
115 | - In the bliss plugin the c_indices derivation using a SHA-512 based random | |
116 | oracle has been fixed, generalized and standardized by employing the MGF1 mask | |
117 | generation function with SHA-512. As a consequence BLISS signatures unsing the | |
118 | improved oracle are not compatible with the earlier implementation. | |
119 | ||
120 | - Support for auto=route with right=%any for transport mode connections has | |
121 | been added (the ikev2/trap-any scenario provides examples). | |
122 | ||
123 | - The starter daemon does not flush IPsec policies and SAs anymore when it is | |
124 | stopped. Already existing duplicate policies are now overwritten by the IKE | |
125 | daemon when it installs its policies. | |
126 | ||
127 | - Init limits (like charon.init_limit_half_open) can now optionally be enforced | |
128 | when initiating SAs via VICI. For this, IKE_SAs initiated by the daemon are | |
129 | now also counted as half-open SAs, which, as a side-effect, fixes the status | |
130 | output while connecting (e.g. in ipsec status). | |
131 | ||
132 | - Symmetric configuration of EAP methods in left|rightauth is now possible when | |
133 | mutual EAP-only authentication is used (previously, the client had to | |
134 | configure rightauth=eap or rightauth=any, which prevented it from using this | |
135 | same config as responder). | |
136 | ||
137 | - The initiator flag in the IKEv2 header is compared again (wasn't the case | |
138 | since 5.0.0) and packets that have the flag set incorrectly are again ignored. | |
139 | ||
a215008c | 140 | - Implemented a demo Hardcopy Device IMC/IMV pair based on the "Hardcopy |
453e204a | 141 | Device Health Assessment Trusted Network Connect Binding" (HCD-TNC) |
a215008c AS |
142 | document drafted by the IEEE Printer Working Group (PWG). |
143 | ||
144 | - Fixed IF-M segmentation which failed in the presence of multiple small | |
145 | attributes in front of a huge attribute to be segmented. | |
146 | ||
39660798 | 147 | |
2b19e517 TB |
148 | strongswan-5.3.2 |
149 | ---------------- | |
150 | ||
151 | - Fixed a vulnerability that allowed rogue servers with a valid certificate | |
152 | accepted by the client to trick it into disclosing its username and even | |
153 | password (if the client accepts EAP-GTC). This was caused because constraints | |
154 | against the responder's authentication were enforced too late. | |
155 | This vulnerability has been registered as CVE-2015-4171. | |
156 | ||
157 | ||
eb423ebb AS |
158 | strongswan-5.3.1 |
159 | ---------------- | |
160 | ||
099260d8 TB |
161 | - Fixed a denial-of-service and potential remote code execution vulnerability |
162 | triggered by IKEv1/IKEv2 messages that contain payloads for the respective | |
163 | other IKE version. Such payload are treated specially since 5.2.2 but because | |
164 | they were still identified by their original payload type they were used as | |
165 | such in some places causing invalid function pointer dereferences. | |
166 | The vulnerability has been registered as CVE-2015-3991. | |
167 | ||
e8ba1d47 MW |
168 | - The new aesni plugin provides CBC, CTR, XCBC, CMAC, CCM and GCM crypto |
169 | primitives for AES-128/192/256. The plugin requires AES-NI and PCLMULQDQ | |
170 | instructions and works on both x86 and x64 architectures. It provides | |
171 | superior crypto performance in userland without any external libraries. | |
172 | ||

c6595222 AS |
174 | strongswan-5.3.0 |
175 | ---------------- | |
176 | ||
4a00f912 MW |
177 | - Added support for IKEv2 make-before-break reauthentication. By using a global |
178 | CHILD_SA reqid allocation mechanism, charon supports overlapping CHILD_SAs. | |
179 | This allows the use of make-before-break instead of the previously supported | |
180 | break-before-make reauthentication, avoiding connectivity gaps during that | |
181 | procedure. As the new mechanism may fail with peers not supporting it (such | |
182 | as any previous strongSwan release) it must be explicitly enabled using | |
183 | the charon.make_before_break strongswan.conf option. | |
184 | ||
3f1ef3a6 TB |
185 | - Support for "Signature Authentication in IKEv2" (RFC 7427) has been added. |
186 | This allows the use of stronger hash algorithms for public key authentication. | |
187 | By default, signature schemes are chosen based on the strength of the | |
188 | signature key, but specific hash algorithms may be configured in leftauth. | |
189 | ||
190 | - Key types and hash algorithms specified in rightauth are now also checked | |
191 | against IKEv2 signature schemes. If such constraints are used for certificate | |
192 | chain validation in existing configurations, in particular with peers that | |
193 | don't support RFC 7427, it may be necessary to disable this feature with the | |
194 | charon.signature_authentication_constraints setting, because the signature | |
195 | scheme used in classic IKEv2 public key authentication may not be strong | |
196 | enough. | |
197 | ||
1e1e88e6 MW |
198 | - The new connmark plugin allows a host to bind conntrack flows to a specific |
199 | CHILD_SA by applying and restoring the SA mark to conntrack entries. This | |
200 | allows a peer to handle multiple transport mode connections coming over the | |
201 | same NAT device for client-initiated flows. A common use case is to protect | |
202 | L2TP/IPsec, as supported by some systems. | |
203 | ||
dc88d179 MW |
204 | - The forecast plugin can forward broadcast and multicast messages between |
205 | connected clients and a LAN. For CHILD_SA using unique marks, it sets up | |
206 | the required Netfilter rules and uses a multicast/broadcast listener that | |
207 | forwards such messages to all connected clients. This plugin is designed for | |
208 | Windows 7 IKEv2 clients, which announces its services over the tunnel if the | |
209 | negotiated IPsec policy allows it. | |
210 | ||
2185c29b MW |
211 | - For the vici plugin a Python Egg has been added to allow Python applications |
212 | to control or monitor the IKE daemon using the VICI interface, similar to the | |
213 | existing ruby gem. The Python library has been contributed by Björn Schuberg. | |
214 | ||
f05a578b MW |
215 | - EAP server methods now can fulfill public key constraints, such as rightcert |
216 | or rightca. Additionally, public key and signature constraints can be | |
217 | specified for EAP methods in the rightauth keyword. Currently the EAP-TLS and | |
218 | EAP-TTLS methods provide verification details to constraints checking. | |
219 | ||
27bd0fed AS |
220 | - Upgrade of the BLISS post-quantum signature algorithm to the improved BLISS-B |
221 | variant. Can be used in conjunction with the SHA256, SHA384 and SHA512 hash | |
222 | algorithms with SHA512 being the default. | |
223 | ||
e0359350 AS |
224 | - The IF-IMV 1.4 interface now makes the IP address of the TNC access requestor |
225 | as seen by the TNC server available to all IMVs. This information can be | |
226 | forwarded to policy enforcement points (e.g. firewalls or routers). | |
227 | ||
7b4a96b2 AS |
228 | - The new mutual tnccs-20 plugin parameter activates mutual TNC measurements |
229 | in PB-TNC half-duplex mode between two endpoints over either a PT-EAP or | |
230 | PT-TLS transport medium. | |
231 | ||

233 | strongswan-5.2.2 |
234 | ---------------- | |
235 | ||
919449a3 TB |
236 | - Fixed a denial-of-service vulnerability triggered by an IKEv2 Key Exchange |
237 | payload that contains the Diffie-Hellman group 1025. This identifier was | |
238 | used internally for DH groups with custom generator and prime. Because | |
239 | these arguments are missing when creating DH objects based on the KE payload | |
240 | an invalid pointer dereference occurred. This allowed an attacker to crash | |
241 | the IKE daemon with a single IKE_SA_INIT message containing such a KE | |
242 | payload. The vulnerability has been registered as CVE-2014-9221. | |
243 | ||
045501d5 MW |
244 | - The left/rightid options in ipsec.conf, or any other identity in strongSwan, |
245 | now accept prefixes to enforce an explicit type, such as email: or fqdn:. | |
246 | Note that no conversion is done for the remaining string, refer to | |
247 | ipsec.conf(5) for details. | |
248 | ||
30a90ccf | 249 | - The post-quantum Bimodal Lattice Signature Scheme (BLISS) can be used as |
32d19652 AS |
250 | an IKEv2 public key authentication method. The pki tool offers full support |
251 | for the generation of BLISS key pairs and certificates. | |
252 | ||
30a90ccf TB |
253 | - Fixed mapping of integrity algorithms negotiated for AH via IKEv1. This could |
254 | cause interoperability issues when connecting to older versions of charon. | |
255 | ||
045501d5 | 256 | |
dcdcae01 MW |
257 | strongswan-5.2.1 |
258 | ---------------- | |
259 | ||
260 | - The new charon-systemd IKE daemon implements an IKE daemon tailored for use | |
261 | with systemd. It avoids the dependency on ipsec starter and uses swanctl | |
262 | as configuration backend, building a simple and lightweight solution. It | |
263 | supports native systemd journal logging. | |
264 | ||
55758bec TB |
265 | - Support for IKEv2 fragmentation as per RFC 7383 has been added. Like IKEv1 |
266 | fragmentation it can be enabled by setting fragmentation=yes in ipsec.conf. | |
267 | ||
e9a93cb7 AS |
268 | - Support of the TCG TNC IF-M Attribute Segmentation specification proposal. |
269 | All attributes can be segmented. Additionally TCG/SWID Tag, TCG/SWID Tag ID | |
270 | and IETF/Installed Packages attributes can be processed incrementally on a | |
271 | per segment basis. | |
272 | ||
9180c921 MW |
273 | - The new ext-auth plugin calls an external script to implement custom IKE_SA |
274 | authorization logic, courtesy of Vyronas Tsingaras. | |
275 | ||
7431ad0d MW |
276 | - For the vici plugin a ruby gem has been added to allow ruby applications |
277 | to control or monitor the IKE daemon. The vici documentation has been updated | |
278 | to include a description of the available operations and some simple examples | |
279 | using both the libvici C interface and the ruby gem. | |

4c5e52f5 MW |
285 | - strongSwan has been ported to the Windows platform. Using a MinGW toolchain, |
286 | many parts of the strongSwan codebase run natively on Windows 7 / 2008 R2 | |
287 | and newer releases. charon-svc implements a Windows IKE service based on | |
288 | libcharon, the kernel-iph and kernel-wfp plugins act as networking and IPsec | |
289 | backend on the Windows platform. socket-win provides a native IKE socket | |
290 | implementation, while winhttp fetches CRL and OCSP information using the | |
291 | WinHTTP API. | |
292 | ||
4787523c MW |
293 | - The new vici plugin provides a Versatile IKE Configuration Interface for |
294 | charon. Using the stable IPC interface, external applications can configure, | |
295 | control and monitor the IKE daemon. Instead of scripting the ipsec tool | |
296 | and generating ipsec.conf, third party applications can use the new interface | |
297 | for more control and better reliability. | |
298 | ||
b30c09ea MW |
299 | - Built upon the libvici client library, swanctl implements the first user of |
300 | the VICI interface. Together with a swanctl.conf configuration file, | |
301 | connections can be defined, loaded and managed. swanctl provides a portable, | |
302 | complete IKE configuration and control interface for the command line. | |
73303700 | 303 | The first six swanctl example scenarios have been added. |
b30c09ea | 304 | |
6048d773 AS |
305 | - The SWID IMV implements a JSON-based REST API which allows the exchange |
306 | of SWID tags and Software IDs with the strongTNC policy manager. | |
307 | ||
37cb91d7 | 308 | - The SWID IMC can extract all installed packages from the dpkg (Debian, |
3d2b36b8 TB |
309 | Ubuntu, Linux Mint etc.), rpm (Fedora, RedHat, OpenSUSE, etc.), or |
310 | pacman (Arch Linux, Manjaro, etc.) package managers, respectively, using the | |
311 | swidGenerator (https://github.com/strongswan/swidGenerator) which generates | |
312 | SWID tags according to the new ISO/IEC 19770-2:2014 standard. | |
37cb91d7 AS |
313 | |
314 | - All IMVs now share the access requestor ID, device ID and product info | |
315 | of an access requestor via a common imv_session object. | |
316 | ||
9b9d5223 AS |
317 | - The Attestation IMC/IMV pair supports the IMA-NG measurement format |
318 | introduced with the Linux 3.13 kernel. | |

41a4d5a4 AS |
320 | - The aikgen tool generates an Attestation Identity Key bound to a TPM. |
321 | ||
03b5def0 | 322 | - Implemented the PT-EAP transport protocol (RFC 7171) for Trusted Network |
6048d773 | 323 | Connect. |

331 | ---------------- | |
332 | ||
e59ce07b TB |
333 | - Fixed an authentication bypass vulnerability triggered by rekeying an |
334 | unestablished IKEv2 SA while it gets actively initiated. This allowed an | |
335 | attacker to trick a peer's IKE_SA state to established, without the need to | |
336 | provide any valid authentication credentials. The vulnerability has been | |
337 | registered as CVE-2014-2338. | |
338 | ||
8101e6aa MW |
339 | - The acert plugin evaluates X.509 Attribute Certificates. Group membership |
340 | information encoded as strings can be used to fulfill authorization checks | |
341 | defined with the rightgroups option. Attribute Certificates can be loaded | |
342 | locally or get exchanged in IKEv2 certificate payloads. | |
343 | ||
344 | - The pki command gained support to generate X.509 Attribute Certificates | |
345 | using the --acert subcommand, while the --print command supports the ac type. | |
346 | The openac utility has been removed in favor of the new pki functionality. | |
347 | ||
7dc7fdea MW |
348 | - The libtls TLS 1.2 implementation as used by EAP-(T)TLS and other protocols |
349 | has been extended by AEAD mode support, currently limited to AES-GCM. | |

352 | strongswan-5.1.2 |
353 | ---------------- | |
354 | ||
c2d5add6 TB |
355 | - A new default configuration file layout is introduced. The new default |
356 | strongswan.conf file mainly includes config snippets from the strongswan.d | |
357 | and strongswan.d/charon directories (the latter containing snippets for all | |
358 | plugins). The snippets, with commented defaults, are automatically | |
359 | generated and installed, if they don't exist yet. They are also installed | |
360 | in $prefix/share/strongswan/templates so existing files can be compared to | |
361 | the current defaults. | |
362 | ||
363 | - As an alternative to the non-extensible charon.load setting, the plugins | |
364 | to load in charon (and optionally other applications) can now be determined | |
365 | via the charon.plugins.<name>.load setting for each plugin (enabled in the | |
366 | new default strongswan.conf file via the charon.load_modular option). | |
367 | The load setting optionally takes a numeric priority value that allows | |
368 | reordering the plugins (otherwise the default plugin order is preserved). | |
369 | ||
370 | - All strongswan.conf settings that were formerly defined in library specific | |
371 | "global" sections are now application specific (e.g. settings for plugins in | |
372 | libstrongswan.plugins can now be set only for charon in charon.plugins). | |
373 | The old options are still supported, which now allows to define defaults for | |
374 | all applications in the libstrongswan section. | |
375 | ||
acc25f29 AS |
376 | - The ntru libstrongswan plugin supports NTRUEncrypt as a post-quantum |
377 | computer IKE key exchange mechanism. The implementation is based on the | |
378 | ntru-crypto library from the NTRUOpenSourceProject. The supported security | |
379 | strengths are ntru112, ntru128, ntru192, and ntru256. Since the private DH | |
380 | group IDs 1030..1033 have been assigned, the strongSwan Vendor ID must be | |
381 | sent (charon.send_vendor_id = yes) in order to use NTRU. | |
382 | ||
800b361e AS |
383 | - Defined a TPMRA remote attestation workitem and added support for it to the |
384 | Attestation IMV. | |
385 | ||
c2d5add6 TB |
386 | - Compatibility issues between IPComp (compress=yes) and leftfirewall=yes as |
387 | well as multiple subnets in left|rightsubnet have been fixed. | |
388 | ||
572582f5 MW |
389 | - When enabling its "session" strongswan.conf option, the xauth-pam plugin opens |
390 | and closes a PAM session for each established IKE_SA. Patch courtesy of | |
391 | Andrea Bonomi. | |
acc25f29 | 392 | |
0cec570a MW |
393 | - The strongSwan unit testing framework has been rewritten without the "check" |
394 | dependency for improved flexibility and portability. It now properly supports | |
395 | multi-threaded and memory leak testing and brings a bunch of new test cases. | |
396 | ||
397 | ||
2b32884d AS |
398 | strongswan-5.1.1 |
399 | ---------------- | |
400 | ||
7b8fbd74 AS |
401 | - Fixed a denial-of-service vulnerability and potential authorization bypass |
402 | triggered by a crafted ID_DER_ASN1_DN ID payload. The cause is an insufficient | |
403 | length check when comparing such identities. The vulnerability has been | |
404 | registered as CVE-2013-6075. | |
405 | ||
406 | - Fixed a denial-of-service vulnerability triggered by a crafted IKEv1 | |
407 | fragmentation payload. The cause is a NULL pointer dereference. The | |
408 | vulnerability has been registered as CVE-2013-6076. | |
409 | ||
2b32884d | 410 | - The lean stand-alone pt-tls-client can set up a RFC 6876 PT-TLS session |
1c1ba803 TB |
411 | with a strongSwan policy enforcement point which uses the tnc-pdp charon |
412 | plugin. | |
2b32884d | 413 | |
fa2f6aa1 AS |
414 | - The new TCG TNC SWID IMC/IMV pair supports targeted SWID requests for either |
415 | full SWID Tag or concise SWID Tag ID inventories. | |
416 | ||
38fb8e4e MW |
417 | - The XAuth backend in eap-radius now supports multiple XAuth exchanges for |
418 | different credential types and display messages. All user input gets | |
419 | concatenated and verified with a single User-Password RADIUS attribute on | |
420 | the AAA. With an AAA supporting it, one for example can implement | |
421 | Password+Token authentication with proper dialogs on iOS and OS X clients. | |
422 | ||
423 | - charon supports IKEv1 Mode Config exchange in push mode. The ipsec.conf | |
424 | modeconfig=push option enables it for both client and server, the same way | |
425 | as pluto used it. | |
426 | ||
390d2b50 MW |
427 | - Using the "ah" ipsec.conf keyword on both IKEv1 and IKEv2 connections, |
428 | charon can negotiate and install Security Associations integrity-protected by | |
429 | the Authentication Header protocol. Supported are plain AH(+IPComp) SAs only, | |
430 | but not the deprecated RFC2401 style ESP+AH bundles. | |
431 | ||
1c1ba803 TB |
432 | - The generation of initialization vectors for IKE and ESP (when using libipsec) |
433 | is now modularized and IVs for e.g. AES-GCM are now correctly allocated | |
434 | sequentially, while other algorithms like AES-CBC still use random IVs. | |
435 | ||
38fb8e4e MW |
436 | - The left and right options in ipsec.conf can take multiple address ranges |
437 | and subnets. This allows connection matching against a larger set of | |
438 | addresses, for example to use a different connection for clients connecting | |
439 | from a internal network. | |
440 | ||
34dff30c AS |
441 | - For all those who have a queasy feeling about the NIST elliptic curve set, |
442 | the Brainpool curves introduced for use with IKE by RFC 6932 might be a | |
443 | more trustworthy alternative. | |
444 | ||
390d2b50 MW |
445 | - The kernel-libipsec userland IPsec backend now supports usage statistics, |
446 | volume based rekeying and accepts ESPv3 style TFC padded packets. | |
447 | ||
1c1ba803 TB |
448 | - With two new strongswan.conf options fwmarks can be used to implement |
449 | host-to-host tunnels with kernel-libipsec. | |
450 | ||
38fb8e4e MW |
451 | - load-tester supports transport mode connections and more complex traffic |
452 | selectors, including such using unique ports for each tunnel. | |
2b32884d | 453 | |
1c1ba803 TB |
454 | - The new dnscert plugin provides support for authentication via CERT RRs that |
455 | are protected via DNSSEC. The plugin was created by Ruslan N. Marchenko. | |
456 | ||
457 | - The eap-radius plugin supports forwarding of several Cisco Unity specific | |
458 | RADIUS attributes in corresponding configuration payloads. | |
459 | ||
460 | - Database transactions are now abstracted and implemented by the two backends. | |
461 | If you use MySQL make sure all tables use the InnoDB engine. | |
462 | ||
390d2b50 MW |
463 | - libstrongswan now can provide an experimental custom implementation of the |
464 | printf family functions based on klibc if neither Vstr nor glibc style printf | |
465 | hooks are available. This can avoid the Vstr dependency on some systems at | |
466 | the cost of slower and less complete printf functions. | |
467 | ||
fa2f6aa1 | 468 | |
40b0a15c MW |
469 | strongswan-5.1.0 |
470 | ---------------- | |
471 | ||
3a938a6f TB |
472 | - Fixed a denial-of-service vulnerability triggered by specific XAuth usernames |
473 | and EAP identities (since 5.0.3), and PEM files (since 4.1.11). The crash | |
474 | was caused by insufficient error handling in the is_asn1() function. | |
475 | The vulnerability has been registered as CVE-2013-5018. | |
476 | ||
40b0a15c MW |
477 | - The new charon-cmd command line IKE client can establish road warrior |
478 | connections using IKEv1 or IKEv2 with different authentication profiles. | |
479 | It does not depend on any configuration files and can be configured using a | |
480 | few simple command line options. | |
481 | ||
482 | - The kernel-pfroute networking backend has been greatly improved. It now | |
78e6f69e | 483 | can install virtual IPs on TUN devices on OS X and FreeBSD, allowing these |
40b0a15c MW |
484 | systems to act as a client in common road warrior scenarios. |
485 | ||
78e6f69e TB |
486 | - The new kernel-libipsec plugin uses TUN devices and libipsec to provide IPsec |
487 | processing in userland on Linux, FreeBSD and Mac OS X. | |
488 | ||
68957d18 MW |
489 | - The eap-radius plugin can now serve as an XAuth backend called xauth-radius, |
490 | directly verifying XAuth credentials using RADIUS User-Name/User-Password | |
491 | attributes. This is more efficient than the existing xauth-eap+eap-radius | |
492 | combination, and allows RADIUS servers without EAP support to act as AAA | |
493 | backend for IKEv1. | |
494 | ||
78e6f69e | 495 | - The new osx-attr plugin installs configuration attributes (currently DNS |
2334ae56 MW |
496 | servers) via SystemConfiguration on Mac OS X. The keychain plugin provides |
497 | certificates from the OS X keychain service. | |
78e6f69e TB |
498 | |
499 | - The sshkey plugin parses SSH public keys, which, together with the --agent | |
500 | option for charon-cmd, allows the use of ssh-agent for authentication. | |
501 | To configure SSH keys in ipsec.conf the left|rightrsasigkey options are | |
502 | replaced with left|rightsigkey, which now take public keys in one of three | |
503 | formats: SSH (RFC 4253, ssh: prefix), DNSKEY (RFC 3110, dns: prefix), and | |
504 | PKCS#1 (the default, no prefix). | |
505 | ||
506 | - Extraction of certificates and private keys from PKCS#12 files is now provided | |
507 | by the new pkcs12 plugin or the openssl plugin. charon-cmd (--p12) as well | |
508 | as charon (via P12 token in ipsec.secrets) can make use of this. | |
509 | ||
40b0a15c MW |
510 | - IKEv2 can now negotiate transport mode and IPComp in NAT situations. |
511 | ||
3a938a6f | 512 | - IKEv2 exchange initiators now properly close an established IKE or CHILD_SA |
40b0a15c MW |
513 | on error conditions using an additional exchange, keeping state in sync |
514 | between peers. | |
515 | ||
226f34e0 | 516 | - Using a SQL database interface a Trusted Network Connect (TNC) Policy Manager |
78e6f69e TB |
517 | can generate specific measurement workitems for an arbitrary number of |
518 | Integrity Measurement Verifiers (IMVs) based on the history of the VPN user | |
519 | and/or device. | |
520 | ||
521 | - Several core classes in libstrongswan are now tested with unit tests. These | |
522 | can be enabled with --enable-unit-tests and run with 'make check'. Coverage | |
523 | reports can be generated with --enable-coverage and 'make coverage' (this | |
524 | disables any optimization, so it should not be enabled when building | |
525 | production releases). | |
526 | ||
56b753ca MW |
527 | - The leak-detective developer tool has been greatly improved. It works much |
528 | faster/stabler with multiple threads, does not use deprecated malloc hooks | |
529 | anymore and has been ported to OS X. | |
530 | ||
78e6f69e TB |
531 | - chunk_hash() is now based on SipHash-2-4 with a random key. This provides |
532 | better distribution and prevents hash flooding attacks when used with | |
533 | hashtables. | |
534 | ||
535 | - All default plugins implement the get_features() method to define features | |
536 | and their dependencies. The plugin loader has been improved, so that plugins | |
537 | in a custom load statement can be ordered freely or to express preferences | |
538 | without being affected by dependencies between plugin features. | |
539 | ||
c3b8335c MW |
540 | - A centralized thread can take care for watching multiple file descriptors |
541 | concurrently. This removes the need for a dedicated listener threads in | |
542 | various plugins. The number of "reserved" threads for such tasks has been | |
543 | reduced to about five, depending on the plugin configuration. | |
544 | ||
545 | - Plugins that can be controlled by a UNIX socket IPC mechanism gained network | |
546 | transparency. Third party applications querying these plugins now can use | |
547 | TCP connections from a different host. | |
548 | ||
78e6f69e | 549 | - libipsec now supports AES-GCM. |
226f34e0 | 550 | |
40b0a15c | 551 | |
2e12fc4b AS |
552 | strongswan-5.0.4 |
553 | ---------------- | |
554 | ||
555 | - Fixed a security vulnerability in the openssl plugin which was reported by | |
556 | Kevin Wojtysiak. The vulnerability has been registered as CVE-2013-2944. | |
557 | Before the fix, if the openssl plugin's ECDSA signature verification was used, | |
558 | due to a misinterpretation of the error code returned by the OpenSSL | |
559 | ECDSA_verify() function, an empty or zeroed signature was accepted as a | |
560 | legitimate one. | |
561 | ||
562 | - The handling of a couple of other non-security relevant openssl return codes | |
563 | was fixed as well. | |
564 | ||
565 | - The tnc_ifmap plugin now publishes virtual IPv4 and IPv6 addresses via its | |
566 | TCG TNC IF-MAP 2.1 interface. | |
567 | ||
568 | - The charon.initiator_only option causes charon to ignore IKE initiation | |
569 | requests. | |
570 | ||
bec5bf02 AS |
571 | - The openssl plugin can now use the openssl-fips library. |
572 | ||
2e12fc4b | 573 | |
d69eb037 TB |
574 | strongswan-5.0.3 |
575 | ---------------- | |
576 | ||
577 | - The new ipseckey plugin enables authentication based on trustworthy public | |
578 | keys stored as IPSECKEY resource records in the DNS and protected by DNSSEC. | |
579 | To do so it uses a DNSSEC enabled resolver, like the one provided by the new | |
580 | unbound plugin, which is based on libldns and libunbound. Both plugins were | |
581 | created by Reto Guadagnini. | |
582 | ||
1fc609fe AS |
583 | - Implemented the TCG TNC IF-IMV 1.4 draft making access requestor identities |
584 | available to an IMV. The OS IMV stores the AR identity together with the | |
585 | device ID in the attest database. | |
586 | ||
587 | - The openssl plugin now uses the AES-NI accelerated version of AES-GCM | |
588 | if the hardware supports it. | |
7a93844f | 589 | |
96776d6f MW |
590 | - The eap-radius plugin can now assign virtual IPs to IKE clients using the |
591 | Framed-IP-Address attribute by using the "%radius" named pool in the | |
592 | rightsourceip ipsec.conf option. Cisco Banner attributes are forwarded to | |
593 | Unity-capable IKEv1 clients during mode config. charon now sends Interim | |
594 | Accounting updates if requested by the RADIUS server, reports | |
595 | sent/received packets in Accounting messages, and adds a Terminate-Cause | |
596 | to Accounting-Stops. | |
597 | ||
598 | - The recently introduced "ipsec listcounters" command can report connection | |
599 | specific counters by passing a connection name, and global or connection | |
600 | counters can be reset by the "ipsec resetcounters" command. | |
601 | ||
602 | - The strongSwan libpttls library provides an experimental implementation of | |
603 | PT-TLS (RFC 6876), a Posture Transport Protocol over TLS. | |
604 | ||
605 | - The charon systime-fix plugin can disable certificate lifetime checks on | |
606 | embedded systems if the system time is obviously out of sync after bootup. | |
607 | Certificates lifetimes get checked once the system time gets sane, closing | |
608 | or reauthenticating connections using expired certificates. | |
609 | ||
610 | - The "ikedscp" ipsec.conf option can set DiffServ code points on outgoing | |
611 | IKE packets. | |
7a93844f | 612 | |
e34666a4 TB |
613 | - The new xauth-noauth plugin allows to use basic RSA or PSK authentication with |
614 | clients that cannot be configured without XAuth authentication. The plugin | |
615 | simply concludes the XAuth exchange successfully without actually performing | |
616 | any authentication. Therefore, to use this backend it has to be selected | |
617 | explicitly with rightauth2=xauth-noauth. | |
618 | ||
db50a35a RB |
619 | - The new charon-tkm IKEv2 daemon delegates security critical operations to a |
620 | separate process. This has the benefit that the network facing daemon has no | |
621 | knowledge of keying material used to protect child SAs. Thus subverting | |
622 | charon-tkm does not result in the compromise of cryptographic keys. | |
623 | The extracted functionality has been implemented from scratch in a minimal TCB | |
624 | (trusted computing base) in the Ada programming language. Further information | |
625 | can be found at http://www.codelabs.ch/tkm/. | |
626 | ||
c2a5e7bc AS |
627 | strongswan-5.0.2 |
628 | ---------------- | |
629 | ||
630 | - Implemented all IETF Standard PA-TNC attributes and an OS IMC/IMV | |
631 | pair using them to transfer operating system information. | |
632 | ||
a19d5913 MW |
633 | - The new "ipsec listcounters" command prints a list of global counter values |
634 | about received and sent IKE messages and rekeyings. | |
635 | ||
343e9989 MW |
636 | - A new lookip plugin can perform fast lookup of tunnel information using a |
637 | clients virtual IP and can send notifications about established or deleted | |
638 | tunnels. The "ipsec lookip" command can be used to query such information | |
639 | or receive notifications. | |
640 | ||
ecdd5aed MW |
641 | - The new error-notify plugin catches some common error conditions and allows |
642 | an external application to receive notifications for them over a UNIX socket. | |
643 | ||
6910e5c7 MW |
644 | - IKE proposals can now use a PRF algorithm different to that defined for |
645 | integrity protection. If an algorithm with a "prf" prefix is defined | |
646 | explicitly (such as prfsha1 or prfsha256), no implicit PRF algorithm based on | |
647 | the integrity algorithm is added to the proposal. | |
c2a5e7bc | 648 | |
8fc7bbc6 MW |
649 | - The pkcs11 plugin can now load leftcert certificates from a smartcard for a |
650 | specific ipsec.conf conn section and cacert CA certificates for a specific ca | |
651 | section. | |
652 | ||
78b2a2b1 MW |
653 | - The load-tester plugin gained additional options for certificate generation |
654 | and can load keys and multiple CA certificates from external files. It can | |
655 | install a dedicated outer IP address for each tunnel and tunnel initiation | |
656 | batches can be triggered and monitored externally using the | |
657 | "ipsec load-tester" tool. | |
658 | ||
cc0cc3b5 MW |
659 | - PKCS#7 container parsing has been modularized, and the openssl plugin |
660 | gained an alternative implementation to decrypt and verify such files. | |
661 | In contrast to our own DER parser, OpenSSL can handle BER files, which is | |
662 | required for interoperability of our scepclient with EJBCA. | |
663 | ||
f31b4180 TB |
664 | - Support for the proprietary IKEv1 fragmentation extension has been added. |
665 | Fragments are always handled on receipt but only sent if supported by the peer | |
666 | and if enabled with the new fragmentation ipsec.conf option. | |
667 | ||
0e0870ae MW |
668 | - IKEv1 in charon can now parse certificates received in PKCS#7 containers and |
669 | supports NAT traversal as used by Windows clients. Patches courtesy of | |
670 | Volker Rümelin. | |
671 | ||
2f0441a3 MW |
672 | - The new rdrand plugin provides a high quality / high performance random |
673 | source using the Intel rdrand instruction found on Ivy Bridge processors. | |
674 | ||
73791223 TB |
675 | - The integration test environment was updated and now uses KVM and reproducible |
676 | guest images based on Debian. | |
677 | ||
1fc609fe | 678 | |
ecfd714c AS |
679 | strongswan-5.0.1 |
680 | ---------------- | |
681 | ||
6f93927b AS |
682 | - Introduced the sending of the standard IETF Assessment Result |
683 | PA-TNC attribute by all strongSwan Integrity Measurement Verifiers. | |
684 | ||
ecfd714c AS |
685 | - Extended PTS Attestation IMC/IMV pair to provide full evidence of |
686 | the Linux IMA measurement process. All pertinent file information | |
6f93927b | 687 | of a Linux OS can be collected and stored in an SQL database. |
ecfd714c AS |
688 | |
689 | - The PA-TNC and PB-TNC protocols can now process huge data payloads | |
690 | >64 kB by distributing PA-TNC attributes over multiple PA-TNC messages | |
691 | and these messages over several PB-TNC batches. As long as no | |
6f93927b | 692 | consolidated recommandation from all IMVs can be obtained, the TNC |
ecfd714c AS |
693 | server requests more client data by sending an empty SDATA batch. |
694 | ||
804d702b MW |
695 | - The rightgroups2 ipsec.conf option can require group membership during |
696 | a second authentication round, for example during XAuth authentication | |
697 | against a RADIUS server. | |
698 | ||
3423b3a8 MW |
699 | - The xauth-pam backend can authenticate IKEv1 XAuth and Hybrid authenticated |
700 | clients against any PAM service. The IKEv2 eap-gtc plugin does not use | |
701 | PAM directly anymore, but can use any XAuth backend to verify credentials, | |
702 | including xauth-pam. | |
703 | ||
cc48f360 MW |
704 | - The new unity plugin brings support for some parts of the IKEv1 Cisco Unity |
705 | Extension. As client, charon narrows traffic selectors to the received | |
706 | Split-Include attributes and automatically installs IPsec bypass policies | |
707 | for received Local-LAN attributes. As server, charon sends Split-Include | |
708 | attributes for leftsubnet definitions containing multiple subnets to Unity- | |
709 | aware clients. | |
710 | ||
cbe244a5 TB |
711 | - An EAP-Nak payload is returned by clients if the gateway requests an EAP |
712 | method that the client does not support. Clients can also request a specific | |
713 | EAP method by configuring that method with leftauth. | |
714 | ||
715 | - The eap-dynamic plugin handles EAP-Nak payloads returned by clients and uses | |
716 | these to select a different EAP method supported/requested by the client. | |
717 | The plugin initially requests the first registered method or the first method | |
718 | configured with charon.plugins.eap-dynamic.preferred. | |
719 | ||
e76f3d0d MW |
720 | - The new left/rightdns options specify connection specific DNS servers to |
721 | request/respond in IKEv2 configuration payloads or IKEv2 mode config. leftdns | |
722 | can be any (comma separated) combination of %config4 and %config6 to request | |
723 | multiple servers, both for IPv4 and IPv6. rightdns takes a list of DNS server | |
724 | IP addresses to return. | |
725 | ||
69e056a2 MW |
726 | - The left/rightsourceip options now accept multiple addresses or pools. |
727 | leftsourceip can be any (comma separated) combination of %config4, %config6 | |
728 | or fixed IP addresses to request. rightsourceip accepts multiple explicitly | |
729 | specified or referenced named pools. | |
730 | ||
731 | - Multiple connections can now share a single address pool when they use the | |
732 | same definition in one of the rightsourceip pools. | |
733 | ||
4a025539 TB |
734 | - The options charon.interfaces_ignore and charon.interfaces_use allow one to |
735 | configure the network interfaces used by the daemon. | |
736 | ||
737 | - The kernel-netlink plugin supports the charon.install_virtual_ip_on option, | |
738 | which specifies the interface on which virtual IP addresses will be installed. | |
739 | If it is not specified the current behavior of using the outbound interface | |
740 | is preserved. | |
741 | ||
742 | - The kernel-netlink plugin tries to keep the current source address when | |
743 | looking for valid routes to reach other hosts. | |
744 | ||
804d702b MW |
745 | - The autotools build has been migrated to use a config.h header. strongSwan |
746 | development headers will get installed during "make install" if | |
747 | --with-dev-headers has been passed to ./configure. | |
748 | ||
749 | - All crypto primitives gained return values for most operations, allowing | |
750 | crypto backends to fail, for example when using hardware accelerators. | |
ecfd714c | 751 | |

d55c2404 TB |
753 | strongswan-5.0.0 |
754 | ---------------- | |
755 | ||
794cdbc5 MW |
756 | - The charon IKE daemon gained experimental support for the IKEv1 protocol. |
757 | Pluto has been removed from the 5.x series, and unless strongSwan is | |
758 | configured with --disable-ikev1 or --disable-ikev2, charon handles both | |
759 | keying protocols. The feature-set of IKEv1 in charon is almost on par with | |
760 | pluto, but currently does not support AH or bundled AH+ESP SAs. Beside | |
761 | RSA/ECDSA, PSK and XAuth, charon also supports the Hybrid authentication | |
762 | mode. Informations for interoperability and migration is available at | |
763 | http://wiki.strongswan.org/projects/strongswan/wiki/CharonPlutoIKEv1. | |
764 | ||
d55c2404 TB |
765 | - Charon's bus_t has been refactored so that loggers and other listeners are |
766 | now handled separately. The single lock was previously cause for deadlocks | |
767 | if extensive listeners, such as the one provided by the updown plugin, wanted | |
768 | to acquire locks that were held by other threads which in turn tried to log | |
769 | messages, and thus were waiting to acquire the same lock currently held by | |
770 | the thread calling the listener. | |
771 | The implemented changes also allow the use of a read/write-lock for the | |
772 | loggers which increases performance if multiple loggers are registered. | |
773 | Besides several interface changes this last bit also changes the semantics | |
774 | for loggers as these may now be called by multiple threads at the same time. | |
775 | ||
ed7186cb TB |
776 | - Source routes are reinstalled if interfaces are reactivated or IP addresses |
777 | reappear. | |
778 | ||
f97c269e TB |
779 | - The thread pool (processor_t) now has more control over the lifecycle of |
780 | a job (see job.h for details). In particular, it now controls the destruction | |
781 | of jobs after execution and the cancellation of jobs during shutdown. Due to | |
782 | these changes the requeueing feature, previously available to callback_job_t | |
783 | only, is now available to all jobs (in addition to a new rescheduling | |
784 | feature). | |
785 | ||
5a6e5e0d MW |
786 | - In addition to trustchain key strength definitions for different public key |
787 | systems, the rightauth option now takes a list of signature hash algorithms | |
788 | considered save for trustchain validation. For example, the setting | |
789 | rightauth=rsa-2048-ecdsa-256-sha256-sha384-sha512 requires a trustchain | |
790 | that uses at least RSA-2048 or ECDSA-256 keys and certificate signatures | |
791 | using SHA-256 or better. | |
792 | ||

93d9a02e TB |
794 | strongswan-4.6.4 |
795 | ---------------- | |
796 | ||
797 | - Fixed a security vulnerability in the gmp plugin. If this plugin was used | |
798 | for RSA signature verification an empty or zeroed signature was handled as | |
799 | a legitimate one. | |
800 | ||
801 | - Fixed several issues with reauthentication and address updates. | |
802 | ||
803 | ||
c224f765 AS |
804 | strongswan-4.6.3 |
805 | ---------------- | |
806 | ||
807 | - The tnc-pdp plugin implements a RADIUS server interface allowing | |
808 | a strongSwan TNC server to act as a Policy Decision Point. | |
809 | ||
4bc7577d MW |
810 | - The eap-radius authentication backend enforces Session-Timeout attributes |
811 | using RFC4478 repeated authentication and acts upon RADIUS Dynamic | |
812 | Authorization extensions, RFC 5176. Currently supported are disconnect | |
813 | requests and CoA messages containing a Session-Timeout. | |
814 | ||
815 | - The eap-radius plugin can forward arbitrary RADIUS attributes from and to | |
816 | clients using custom IKEv2 notify payloads. The new radattr plugin reads | |
817 | attributes to include from files and prints received attributes to the | |
818 | console. | |
c224f765 AS |
819 | |
820 | - Added support for untruncated MD5 and SHA1 HMACs in ESP as used in | |
821 | RFC 4595. | |
822 | ||
d7590217 TB |
823 | - The cmac plugin implements the AES-CMAC-96 and AES-CMAC-PRF-128 algorithms |
824 | as defined in RFC 4494 and RFC 4615, respectively. | |
825 | ||
4e2e77d5 | 826 | - The resolve plugin automatically installs nameservers via resolvconf(8), |
a281494a | 827 | if it is installed, instead of modifying /etc/resolv.conf directly. |
c224f765 | 828 | |
5f1931ad AS |
829 | - The IKEv2 charon daemon supports now raw RSA public keys in RFC 3110 |
830 | DNSKEY and PKCS#1 file format. | |
831 | ||
832 | ||
60e99b37 AS |
833 | strongswan-4.6.2 |
834 | ---------------- | |
835 | ||
836 | - Upgraded the TCG IF-IMC and IF-IMV C API to the upcoming version 1.3 | |
837 | which supports IF-TNCCS 2.0 long message types, the exclusive flags | |
838 | and multiple IMC/IMV IDs. Both the TNC Client and Server as well as | |
839 | the "Test", "Scanner", and "Attestation" IMC/IMV pairs were updated. | |
840 | ||
841 | - Fully implemented the "TCG Attestation PTS Protocol: Binding to IF-M" | |
842 | standard (TLV-based messages only). TPM-based remote attestation of | |
de4a0c83 AS |
843 | Linux IMA (Integrity Measurement Architecture) possible. Measurement |
844 | reference values are automatically stored in an SQLite database. | |
60e99b37 | 845 | |
a345aa26 MW |
846 | - The EAP-RADIUS authentication backend supports RADIUS accounting. It sends |
847 | start/stop messages containing Username, Framed-IP and Input/Output-Octets | |
848 | attributes and has been tested against FreeRADIUS and Microsoft NPS. | |
60e99b37 | 849 | |
de4a0c83 AS |
850 | - Added support for PKCS#8 encoded private keys via the libstrongswan |
851 | pkcs8 plugin. This is the default format used by some OpenSSL tools since | |
852 | version 1.0.0 (e.g. openssl req with -keyout). | |
dcefa267 | 853 | |
a8958012 MW |
854 | - Added session resumption support to the strongSwan TLS stack. |
855 | ||
de4a0c83 | 856 | |
acb92cb4 AS |
857 | strongswan-4.6.1 |
858 | ---------------- | |
859 | ||
860 | - Because of changing checksums before and after installation which caused | |
861 | the integrity tests to fail we avoided directly linking libsimaka, libtls and | |
862 | libtnccs to those libcharon plugins which make use of these dynamic libraries. | |
18f85b66 AS |
863 | Instead we linked the libraries to the charon daemon. Unfortunately Ubuntu |
864 | 11.10 activated the --as-needed ld option which discards explicit links | |
865 | to dynamic libraries that are not actually used by the charon daemon itself, | |
866 | thus causing failures during the loading of the plugins which depend on these | |
867 | libraries for resolving external symbols. | |
acb92cb4 AS |
868 | |
869 | - Therefore our approach of computing integrity checksums for plugins had to be | |
870 | changed radically by moving the hash generation from the compilation to the | |
871 | post-installation phase. | |

92a1b234 | 874 | strongswan-4.6.0 |
5a2e2e0b AS |
875 | ---------------- |
876 | ||
37276728 MW |
877 | - The new libstrongswan certexpire plugin collects expiration information of |
878 | all used certificates and exports them to CSV files. It either directly | |
879 | exports them or uses cron style scheduling for batch exports. | |
880 | ||
881 | - starter passes unresolved hostnames to charon, allowing it to do name | |
882 | resolution not before the connection attempt. This is especially useful with | |
883 | connections between hosts using dynamic IP addresses. Thanks to Mirko Parthey | |
884 | for the initial patch. | |
885 | ||
5fd8e530 TB |
886 | - The android plugin can now be used without the Android frontend patch and |
887 | provides DNS server registration and logging to logcat. | |
888 | ||
889 | - Pluto and starter (plus stroke and whack) have been ported to Android. | |
890 | ||
602ee58e TB |
891 | - Support for ECDSA private and public key operations has been added to the |
892 | pkcs11 plugin. The plugin now also provides DH and ECDH via PKCS#11 and can | |
893 | use tokens as random number generators (RNG). By default only private key | |
894 | operations are enabled, more advanced features have to be enabled by their | |
895 | option in strongswan.conf. This also applies to public key operations (even | |
896 | for keys not stored on the token) which were enabled by default before. | |
897 | ||
37276728 MW |
898 | - The libstrongswan plugin system now supports detailed plugin dependencies. |
899 | Many plugins have been extended to export its capabilities and requirements. | |
900 | This allows the plugin loader to resolve plugin loading order automatically, | |
901 | and in future releases, to dynamically load the required features on demand. | |
902 | Existing third party plugins are source (but not binary) compatible if they | |
903 | properly initialize the new get_features() plugin function to NULL. | |
904 | ||
fd81ac05 AS |
905 | - The tnc-ifmap plugin implements a TNC IF-MAP 2.0 client which can deliver |
906 | metadata about IKE_SAs via a SOAP interface to a MAP server. The tnc-ifmap | |
907 | plugin requires the Apache Axis2/C library. | |
908 | ||
37276728 | 909 | |
5d179d19 AS |
910 | strongswan-4.5.3 |
911 | ---------------- | |
912 | ||
a7edbd21 | 913 | - Our private libraries (e.g. libstrongswan) are not installed directly in |
b18a697a AS |
914 | prefix/lib anymore. Instead a subdirectory is used (prefix/lib/ipsec/ by |
915 | default). The plugins directory is also moved from libexec/ipsec/ to that | |
a7edbd21 TB |
916 | directory. |
917 | ||
b18a697a AS |
918 | - The dynamic IMC/IMV libraries were moved from the plugins directory to |
919 | a new imcvs directory in the prefix/lib/ipsec/ subdirectory. | |
920 | ||
107ea60f TB |
921 | - Job priorities were introduced to prevent thread starvation caused by too |
922 | many threads handling blocking operations (such as CRL fetching). Refer to | |
923 | strongswan.conf(5) for details. | |
924 | ||
925 | - Two new strongswan.conf options allow to fine-tune performance on IKEv2 | |
926 | gateways by dropping IKE_SA_INIT requests on high load. | |
927 | ||
f8799170 | 928 | - IKEv2 charon daemon supports start PASS and DROP shunt policies |
b18a697a | 929 | preventing traffic to go through IPsec connections. Installation of the |
107ea60f TB |
930 | shunt policies either via the XFRM netfilter or PFKEYv2 IPsec kernel |
931 | interfaces. | |
f8799170 | 932 | |
93095183 TB |
933 | - The history of policies installed in the kernel is now tracked so that e.g. |
934 | trap policies are correctly updated when reauthenticated SAs are terminated. | |
935 | ||
b18a697a AS |
936 | - IMC/IMV Scanner pair implementing the RFC 5792 PA-TNC (IF-M) protocol. |
937 | Using "netstat -l" the IMC scans open listening ports on the TNC client | |
938 | and sends a port list to the IMV which based on a port policy decides if | |
939 | the client is admitted to the network. | |
940 | (--enable-imc-scanner/--enable-imv-scanner). | |
941 | ||
942 | - IMC/IMV Test pair implementing the RFC 5792 PA-TNC (IF-M) protocol. | |
5d179d19 AS |
943 | (--enable-imc-test/--enable-imv-test). |
944 | ||
4876f896 MW |
945 | - The IKEv2 close action does not use the same value as the ipsec.conf dpdaction |
946 | setting, but the value defined by its own closeaction keyword. The action | |
947 | is triggered if the remote peer closes a CHILD_SA unexpectedly. | |
5d179d19 | 948 | |
5a2e2e0b | 949 | |
6f2378c1 AS |
950 | strongswan-4.5.2 |
951 | ---------------- | |
952 | ||
320e98c2 MW |
953 | - The whitelist plugin for the IKEv2 daemon maintains an in-memory identity |
954 | whitelist. Any connection attempt of peers not whitelisted will get rejected. | |
955 | The 'ipsec whitelist' utility provides a simple command line frontend for | |
956 | whitelist administration. | |
957 | ||
92ebb7c5 | 958 | - The duplicheck plugin provides a specialized form of duplicate checking, |
5832d505 | 959 | doing a liveness check on the old SA and optionally notify a third party |
92ebb7c5 MW |
960 | application about detected duplicates. |
961 | ||
962 | - The coupling plugin permanently couples two or more devices by limiting | |
963 | authentication to previously used certificates. | |
964 | ||
6f2378c1 AS |
965 | - In the case that the peer config and child config don't have the same name |
966 | (usually in SQL database defined connections), ipsec up|route <peer config> | |
967 | starts|routes all associated child configs and ipsec up|route <child config> | |
968 | only starts|routes the specific child config. | |
969 | ||
6ca05fe2 AS |
970 | - fixed the encoding and parsing of X.509 certificate policy statements (CPS). |
971 | ||
1ee7440b AS |
972 | - Duncan Salerno contributed the eap-sim-pcsc plugin implementing a |
973 | pcsc-lite based SIM card backend. | |
974 | ||
975 | - The eap-peap plugin implements the EAP PEAP protocol. Interoperates | |
2778b664 | 976 | successfully with a FreeRADIUS server and Windows 7 Agile VPN clients. |
1ee7440b | 977 | |
cf6ca6d7 MW |
978 | - The IKEv2 daemon charon rereads strongswan.conf on SIGHUP and instructs |
979 | all plugins to reload. Currently only the eap-radius and the attr plugins | |
980 | support configuration reloading. | |
981 | ||
d3d21c29 MW |
982 | - Added userland support to the IKEv2 daemon for Extended Sequence Numbers |
983 | support coming with Linux 2.6.39. To enable ESN on a connection, add | |
984 | the 'esn' keyword to the proposal. The default proposal uses 32-bit sequence | |
985 | numbers only ('noesn'), and the same value is used if no ESN mode is | |
986 | specified. To negotiate ESN support with the peer, include both, e.g. | |
987 | esp=aes128-sha1-esn-noesn. | |
988 | ||
989 | - In addition to ESN, Linux 2.6.39 gained support for replay windows larger | |
990 | than 32 packets. The new global strongswan.conf option 'charon.replay_window' | |
991 | configures the size of the replay window, in packets. | |
992 | ||
6f2378c1 | 993 | |
41ba5ce7 AS |
994 | strongswan-4.5.1 |
995 | ---------------- | |
996 | ||
1b7e081b AS |
997 | - Sansar Choinyambuu implemented the RFC 5793 Posture Broker Protocol (BP) |
998 | compatible with Trusted Network Connect (TNC). The TNCCS 2.0 protocol | |
5cdaafef | 999 | requires the tnccs_20, tnc_imc and tnc_imv plugins but does not depend |
1b7e081b AS |
1000 | on the libtnc library. Any available IMV/IMC pairs conforming to the |
1001 | Trusted Computing Group's TNC-IF-IMV/IMC 1.2 interface specification | |
e44817df | 1002 | can be loaded via /etc/tnc_config. |
1b7e081b | 1003 | |
5cdaafef AS |
1004 | - Re-implemented the TNCCS 1.1 protocol by using the tnc_imc and tnc_imv |
1005 | in place of the external libtnc library. | |
1006 | ||
1007 | - The tnccs_dynamic plugin loaded on a TNC server in addition to the | |
1008 | tnccs_11 and tnccs_20 plugins, dynamically detects the IF-TNCCS | |
1009 | protocol version used by a TNC client and invokes an instance of | |
1010 | the corresponding protocol stack. | |
1011 | ||
41ba5ce7 AS |
1012 | - IKE and ESP proposals can now be stored in an SQL database using a |
1013 | new proposals table. The start_action field in the child_configs | |
1014 | tables allows the automatic starting or routing of connections stored | |
1015 | in an SQL database. | |
1016 | ||
1b7e081b AS |
1017 | - The new certificate_authorities and certificate_distribution_points |
1018 | tables make it possible to store CRL and OCSP Certificate Distribution | |
1019 | points in an SQL database. | |
1020 | ||
ae09bc62 TB |
1021 | - The new 'include' statement allows to recursively include other files in |
1022 | strongswan.conf. Existing sections and values are thereby extended and | |
1023 | replaced, respectively. | |
1024 | ||
1025 | - Due to the changes in the parser for strongswan.conf, the configuration | |
1026 | syntax for the attr plugin has changed. Previously, it was possible to | |
1027 | specify multiple values of a specific attribute type by adding multiple | |
1028 | key/value pairs with the same key (e.g. dns) to the plugins.attr section. | |
1029 | Because values with the same key now replace previously defined values | |
1030 | this is not possible anymore. As an alternative, multiple values can be | |
1031 | specified by separating them with a comma (e.g. dns = 1.2.3.4, 2.3.4.5). | |
1032 | ||
840e7044 AS |
1033 | - ipsec listalgs now appends (set in square brackets) to each crypto |
1034 | algorithm listed the plugin that registered the function. | |
1035 | ||
e44817df MW |
1036 | - Traffic Flow Confidentiality padding supported with Linux 2.6.38 can be used |
1037 | by the IKEv2 daemon. The ipsec.conf 'tfc' keyword pads all packets to a given | |
1038 | boundary, the special value '%mtu' pads all packets to the path MTU. | |
1039 | ||
78a547c9 MW |
1040 | - The new af-alg plugin can use various crypto primitives of the Linux Crypto |
1041 | API using the AF_ALG interface introduced with 2.6.38. This removes the need | |
1042 | for additional userland implementations of symmetric cipher, hash, hmac and | |
1043 | xcbc algorithms. | |
44582075 | 1044 | |
41ed0294 | 1045 | - The IKEv2 daemon supports the INITIAL_CONTACT notify as initiator and |
983a5e88 MW |
1046 | responder. The notify is sent when initiating configurations with a unique |
1047 | policy, set in ipsec.conf via the global 'uniqueids' option. | |
41ed0294 | 1048 | |
f0783464 MW |
1049 | - The conftest conformance testing framework enables the IKEv2 stack to perform |
1050 | many tests using a distinct tool and configuration frontend. Various hooks | |
1051 | can alter reserved bits, flags, add custom notifies and proposals, reorder | |
1052 | or drop messages and much more. It is enabled using the --enable-conftest | |
1053 | ./configure switch. | |
1054 | ||
77eee25f | 1055 | - The new libstrongswan constraints plugin provides advanced X.509 constraint |
cf95d292 | 1056 | checking. In addition to X.509 pathLen constraints, the plugin checks for |
77eee25f MW |
1057 | nameConstraints and certificatePolicies, including policyMappings and |
1058 | policyConstraints. The x509 certificate plugin and the pki tool have been | |
96c4addc MW |
1059 | enhanced to support these extensions. The new left/rightcertpolicy ipsec.conf |
1060 | connection keywords take OIDs a peer certificate must have. | |
1061 | ||
1062 | - The left/rightauth ipsec.conf keywords accept values with a minimum strength | |
1063 | for trustchain public keys in bits, such as rsa-2048 or ecdsa-256. | |
77eee25f | 1064 | |
fb1e7df1 MW |
1065 | - The revocation and x509 libstrongswan plugins and the pki tool gained basic |
1066 | support for delta CRLs. | |
1067 | ||
5cdaafef | 1068 | |
44582075 MW |
1069 | strongswan-4.5.0 |
1070 | ---------------- | |
1071 | ||
b14923ec AS |
1072 | - IMPORTANT: the default keyexchange mode 'ike' is changing with release 4.5 |
1073 | from 'ikev1' to 'ikev2', thus commemorating the five year anniversary of the | |
ac544be2 | 1074 | IKEv2 RFC 4306 and its mature successor RFC 5996. The time has definitively |
b14923ec | 1075 | come for IKEv1 to go into retirement and to cede its place to the much more |
ac544be2 | 1076 | robust, powerful and versatile IKEv2 protocol! |
b14923ec | 1077 | |
44582075 MW |
1078 | - Added new ctr, ccm and gcm plugins providing Counter, Counter with CBC-MAC |
1079 | and Galois/Counter Modes based on existing CBC implementations. These | |
1080 | new plugins bring support for AES and Camellia Counter and CCM algorithms | |
1081 | and the AES GCM algorithms for use in IKEv2. | |
1082 | ||
84c9bc42 MW |
1083 | - The new pkcs11 plugin brings full Smartcard support to the IKEv2 daemon and |
1084 | the pki utility using one or more PKCS#11 libraries. It currently supports | |
61df42cc | 1085 | RSA private and public key operations and loads X.509 certificates from |
84c9bc42 MW |
1086 | tokens. |
1087 | ||
a782b52f MW |
1088 | - Implemented a general purpose TLS stack based on crypto and credential |
1089 | primitives of libstrongswan. libtls supports TLS versions 1.0, 1.1 and 1.2, | |
1090 | ECDHE-ECDSA/RSA, DHE-RSA and RSA key exchange algorithms and RSA/ECDSA based | |
1091 | client authentication. | |
1092 | ||
1093 | - Based on libtls, the eap-tls plugin brings certificate based EAP | |
1094 | authentication for client and server. It is compatible to Windows 7 IKEv2 | |
61df42cc | 1095 | Smartcard authentication and the OpenSSL based FreeRADIUS EAP-TLS backend. |
a782b52f | 1096 | |
8a1353fc AS |
1097 | - Implemented the TNCCS 1.1 Trusted Network Connect protocol using the |
1098 | libtnc library on the strongSwan client and server side via the tnccs_11 | |
1099 | plugin and optionally connecting to a TNC@FHH-enhanced FreeRADIUS AAA server. | |
1100 | Depending on the resulting TNC Recommendation, strongSwan clients are granted | |
1101 | access to a network behind a strongSwan gateway (allow), are put into a | |
ac544be2 | 1102 | remediation zone (isolate) or are blocked (none), respectively. Any number |
8a1353fc AS |
1103 | of Integrity Measurement Collector/Verifier pairs can be attached |
1104 | via the tnc-imc and tnc-imv charon plugins. | |
1105 | ||
b3cabd1f TB |
1106 | - The IKEv1 daemon pluto now uses the same kernel interfaces as the IKEv2 |
1107 | daemon charon. As a result of this, pluto now supports xfrm marks which | |
1108 | were introduced in charon with 4.4.1. | |
1109 | ||
1110 | - Applets for Maemo 5 (Nokia) allow to easily configure and control IKEv2 | |
1111 | based VPN connections with EAP authentication on supported devices. | |
1112 | ||
18a4f865 MW |
1113 | - The RADIUS plugin eap-radius now supports multiple RADIUS servers for |
1114 | redundant setups. Servers are selected by a defined priority, server load and | |
1115 | availability. | |
1116 | ||
1117 | - The simple led plugin controls hardware LEDs through the Linux LED subsystem. | |
1118 | It currently shows activity of the IKE daemon and is a good example how to | |
1119 | implement a simple event listener. | |
1120 | ||
b3cabd1f TB |
1121 | - Improved MOBIKE behavior in several corner cases, for instance, if the |
1122 | initial responder moves to a different address. | |
1123 | ||
1124 | - Fixed left-/rightnexthop option, which was broken since 4.4.0. | |
1125 | ||
3f84e2d6 AS |
1126 | - Fixed a bug not releasing a virtual IP address to a pool if the XAUTH |
1127 | identity was different from the IKE identity. | |
1128 | ||
f6032361 AS |
1129 | - Fixed the alignment of ModeConfig messages on 4-byte boundaries in the |
1130 | case where the attributes are not a multiple of 4 bytes (e.g. Cisco's | |
1131 | UNITY_BANNER). | |
1132 | ||
1133 | - Fixed the interoperability of the socket_raw and socket_default | |
1134 | charon plugins. | |
1135 | ||
3f84e2d6 AS |
1136 | - Added man page for strongswan.conf |
1137 | ||
a782b52f | 1138 | |
03b5e4d8 AS |
1139 | strongswan-4.4.1 |
1140 | ---------------- | |
1141 | ||
ec40c02a | 1142 | - Support of xfrm marks in IPsec SAs and IPsec policies introduced |
b22bb9f2 AS |
1143 | with the Linux 2.6.34 kernel. For details see the example scenarios |
1144 | ikev2/nat-two-rw-mark, ikev2/rw-nat-mark-in-out and ikev2/net2net-psk-dscp. | |
ec40c02a | 1145 | |
b22bb9f2 | 1146 | - The PLUTO_MARK_IN and PLUTO_ESP_ENC environment variables can be used |
b59340a2 AS |
1147 | in a user-specific updown script to set marks on inbound ESP or |
1148 | ESP_IN_UDP packets. | |
e87b78c6 | 1149 | |
3561cc4b AS |
1150 | - The openssl plugin now supports X.509 certificate and CRL functions. |
1151 | ||
e9448cfc | 1152 | - OCSP/CRL checking in IKEv2 has been moved to the revocation plugin, enabled |
b59340a2 | 1153 | by default. Plase update manual load directives in strongswan.conf. |
e9448cfc MW |
1154 | |
1155 | - RFC3779 ipAddrBlock constraint checking has been moved to the addrblock | |
1156 | plugin, disabled by default. Enable it and update manual load directives | |
1157 | in strongswan.conf, if required. | |
1158 | ||
7f3a9468 MW |
1159 | - The pki utility supports CRL generation using the --signcrl command. |
1160 | ||
1161 | - The ipsec pki --self, --issue and --req commands now support output in | |
1162 | PEM format using the --outform pem option. | |
1163 | ||
03b5e4d8 AS |
1164 | - The major refactoring of the IKEv1 Mode Config functionality now allows |
1165 | the transport and handling of any Mode Config attribute. | |
1166 | ||
e87b78c6 | 1167 | - The RADIUS proxy plugin eap-radius now supports multiple servers. Configured |
b59340a2 AS |
1168 | servers are chosen randomly, with the option to prefer a specific server. |
1169 | Non-responding servers are degraded by the selection process. | |
e87b78c6 | 1170 | |
c5c6f9b6 AS |
1171 | - The ipsec pool tool manages arbitrary configuration attributes stored |
1172 | in an SQL database. ipsec pool --help gives the details. | |
1173 | ||
fe2434cf MW |
1174 | - The new eap-simaka-sql plugin acts as a backend for EAP-SIM and EAP-AKA, |
1175 | reading triplets/quintuplets from an SQL database. | |
1176 | ||
c8bd06c7 MW |
1177 | - The High Availability plugin now supports a HA enabled in-memory address |
1178 | pool and Node reintegration without IKE_SA rekeying. The latter allows | |
1179 | clients without IKE_SA rekeying support to keep connected during | |
1180 | reintegration. Additionally, many other issues have been fixed in the ha | |
1181 | plugin. | |
1c1f132a | 1182 | |
c5c921bf MW |
1183 | - Fixed a potential remote code execution vulnerability resulting from |
1184 | the misuse of snprintf(). The vulnerability is exploitable by | |
1185 | unauthenticated users. | |
1186 | ||
03b5e4d8 | 1187 | |
00c60592 MW |
1188 | strongswan-4.4.0 |
1189 | ---------------- | |
1190 | ||
d101a61f MW |
1191 | - The IKEv2 High Availability plugin has been integrated. It provides |
1192 | load sharing and failover capabilities in a cluster of currently two nodes, | |
1193 | based on an extend ClusterIP kernel module. More information is available at | |
1194 | http://wiki.strongswan.org/projects/strongswan/wiki/HighAvailability. | |
9235edc2 | 1195 | The development of the High Availability functionality was sponsored by |
d101a61f MW |
1196 | secunet Security Networks AG. |
1197 | ||
dd8cb2b0 AS |
1198 | - Added IKEv1 and IKEv2 configuration support for the AES-GMAC |
1199 | authentication-only ESP cipher. Our aes_gmac kernel patch or a Linux | |
1200 | 2.6.34 kernel is required to make AES-GMAC available via the XFRM | |
1201 | kernel interface. | |
1202 | ||
4590260b MW |
1203 | - Added support for Diffie-Hellman groups 22, 23 and 24 to the gmp, gcrypt |
1204 | and openssl plugins, usable by both pluto and charon. The new proposal | |
1205 | keywords are modp1024s160, modp2048s224 and modp2048s256. Thanks to Joy Latten | |
1206 | from IBM for his contribution. | |
1207 | ||
9235edc2 AS |
1208 | - The IKEv1 pluto daemon supports RAM-based virtual IP pools using |
1209 | the rightsourceip directive with a subnet from which addresses | |
1210 | are allocated. | |
1211 | ||
d6457833 AS |
1212 | - The ipsec pki --gen and --pub commands now allow the output of |
1213 | private and public keys in PEM format using the --outform pem | |
1214 | command line option. | |
1215 | ||
2d097a0b MW |
1216 | - The new DHCP plugin queries virtual IP addresses for clients from a DHCP |
1217 | server using broadcasts, or a defined server using the | |
1218 | charon.plugins.dhcp.server strongswan.conf option. DNS/WINS server information | |
1219 | is additionally served to clients if the DHCP server provides such | |
1220 | information. The plugin is used in ipsec.conf configurations having | |
1221 | rightsourceip set to %dhcp. | |
1222 | ||
6d6994c6 MW |
1223 | - A new plugin called farp fakes ARP responses for virtual IP addresses |
1224 | handed out to clients from the IKEv2 daemon charon. The plugin lets a | |
89bf11d2 | 1225 | road-warrior act as a client on the local LAN if it uses a virtual IP |
6d6994c6 MW |
1226 | from the responders subnet, e.g. acquired using the DHCP plugin. |
1227 | ||
00c60592 MW |
1228 | - The existing IKEv2 socket implementations have been migrated to the |
1229 | socket-default and the socket-raw plugins. The new socket-dynamic plugin | |
1230 | binds sockets dynamically to ports configured via the left-/rightikeport | |
1231 | ipsec.conf connection parameters. | |
1232 | ||
3e6b50ed MW |
1233 | - The android charon plugin stores received DNS server information as "net.dns" |
1234 | system properties, as used by the Android platform. | |
00c60592 | 1235 | |
d6457833 | 1236 | |
4c68a85a AS |
1237 | strongswan-4.3.6 |
1238 | ---------------- | |
1239 | ||
cdad91de | 1240 | - The IKEv2 daemon supports RFC 3779 IP address block constraints |
e98a4d80 AS |
1241 | carried as a critical X.509v3 extension in the peer certificate. |
1242 | ||
a7155606 AS |
1243 | - The ipsec pool --add|del dns|nbns command manages DNS and NBNS name |
1244 | server entries that are sent via the IKEv1 Mode Config or IKEv2 | |
1245 | Configuration Payload to remote clients. | |
1246 | ||
f721e0fb AS |
1247 | - The Camellia cipher can be used as an IKEv1 encryption algorithm. |
1248 | ||
4c68a85a AS |
1249 | - The IKEv1 and IKEV2 daemons now check certificate path length constraints. |
1250 | ||
909c0c3d MW |
1251 | - The new ipsec.conf conn option "inactivity" closes a CHILD_SA if no traffic |
1252 | was sent or received within the given interval. To close the complete IKE_SA | |
1253 | if its only CHILD_SA was inactive, set the global strongswan.conf option | |
aa9eeb5d MW |
1254 | "charon.inactivity_close_ike" to yes. |
1255 | ||
44e41c4c AS |
1256 | - More detailed IKEv2 EAP payload information in debug output |
1257 | ||
2b2c69e9 | 1258 | - IKEv2 EAP-SIM and EAP-AKA share joint libsimaka library |
44e41c4c | 1259 | |
52fd0ef9 MW |
1260 | - Added required userland changes for proper SHA256 and SHA384/512 in ESP that |
1261 | will be introduced with Linux 2.6.33. The "sha256"/"sha2_256" keyword now | |
1262 | configures the kernel with 128 bit truncation, not the non-standard 96 | |
1263 | bit truncation used by previous releases. To use the old 96 bit truncation | |
1264 | scheme, the new "sha256_96" proposal keyword has been introduced. | |
4c68a85a | 1265 | |
2b2c69e9 MW |
1266 | - Fixed IPComp in tunnel mode, stripping out the duplicated outer header. This |
1267 | change makes IPcomp tunnel mode connections incompatible with previous | |
1268 | releases; disable compression on such tunnels. | |
1269 | ||
6ec949e0 MW |
1270 | - Fixed BEET mode connections on recent kernels by installing SAs with |
1271 | appropriate traffic selectors, based on a patch by Michael Rossberg. | |
1272 | ||
cdad91de MW |
1273 | - Using extensions (such as BEET mode) and crypto algorithms (such as twofish, |
1274 | serpent, sha256_96) allocated in the private use space now require that we | |
1275 | know its meaning, i.e. we are talking to strongSwan. Use the new | |
1276 | "charon.send_vendor_id" option in strongswan.conf to let the remote peer know | |
1277 | this is the case. | |
1278 | ||
aca9f9ab MW |
1279 | - Experimental support for draft-eronen-ipsec-ikev2-eap-auth, where the |
1280 | responder omits public key authentication in favor of a mutual authentication | |
1281 | method. To enable EAP-only authentication, set rightauth=eap on the responder | |
1282 | to rely only on the MSK constructed AUTH payload. This not-yet standardized | |
1283 | extension requires the strongSwan vendor ID introduced above. | |
1284 | ||
0a975307 AS |
1285 | - The IKEv1 daemon ignores the Juniper SRX notification type 40001, thus |
1286 | allowing interoperability. | |
1287 | ||
1288 | ||
b6b90b68 MW |
1289 | strongswan-4.3.5 |
1290 | ---------------- | |
1291 | ||
628f023d AS |
1292 | - The IKEv1 pluto daemon can now use SQL-based address pools to deal out |
1293 | virtual IP addresses as a Mode Config server. The pool capability has been | |
1294 | migrated from charon's sql plugin to a new attr-sql plugin which is loaded | |
b42bfc79 | 1295 | by libstrongswan and which can be used by both daemons either with a SQLite |
628f023d AS |
1296 | or MySQL database and the corresponding plugin. |
1297 | ||
b42bfc79 MW |
1298 | - Plugin names have been streamlined: EAP plugins now have a dash after eap |
1299 | (e.g. eap-sim), as it is used with the --enable-eap-sim ./configure option. | |
1300 | Plugin configuration sections in strongswan.conf now use the same name as the | |
1301 | plugin itself (i.e. with a dash). Make sure to update "load" directives and | |
1302 | the affected plugin sections in existing strongswan.conf files. | |
1303 | ||
d245f5cf AS |
1304 | - The private/public key parsing and encoding has been split up into |
1305 | separate pkcs1, pgp, pem and dnskey plugins. The public key implementation | |
1306 | plugins gmp, gcrypt and openssl can all make use of them. | |
b6b90b68 | 1307 | |
55b045ab MW |
1308 | - The EAP-AKA plugin can use different backends for USIM/quintuplet |
1309 | calculations, very similar to the EAP-SIM plugin. The existing 3GPP2 software | |
1310 | implementation has been migrated to a separate plugin. | |
1311 | ||
d245f5cf | 1312 | - The IKEv2 daemon charon gained basic PGP support. It can use locally installed |
b6b90b68 MW |
1313 | peer certificates and can issue signatures based on RSA private keys. |
1314 | ||
1315 | - The new 'ipsec pki' tool provides a set of commands to maintain a public | |
1316 | key infrastructure. It currently supports operations to create RSA and ECDSA | |
1317 | private/public keys, calculate fingerprints and issue or verify certificates. | |
1318 | ||
1319 | - Charon uses a monotonic time source for statistics and job queueing, behaving | |
1320 | correctly if the system time changes (e.g. when using NTP). | |
1321 | ||
1322 | - In addition to time based rekeying, charon supports IPsec SA lifetimes based | |
1323 | on processed volume or number of packets. They new ipsec.conf paramaters | |
1324 | 'lifetime' (an alias to 'keylife'), 'lifebytes' and 'lifepackets' handle | |
1325 | SA timeouts, while the parameters 'margintime' (an alias to rekeymargin), | |
1326 | 'marginbytes' and 'marginpackets' trigger the rekeying before a SA expires. | |
1327 | The existing parameter 'rekeyfuzz' affects all margins. | |
1328 | ||
85af7a89 MW |
1329 | - If no CA/Gateway certificate is specified in the NetworkManager plugin, |
1330 | charon uses a set of trusted root certificates preinstalled by distributions. | |
1331 | The directory containing CA certificates can be specified using the | |
1332 | --with-nm-ca-dir=path configure option. | |
1333 | ||
b80fa9ca | 1334 | - Fixed the encoding of the Email relative distinguished name in left|rightid |
509f70c1 | 1335 | statements. |
b80fa9ca | 1336 | |
509f70c1 AS |
1337 | - Fixed the broken parsing of PKCS#7 wrapped certificates by the pluto daemon. |
1338 | ||
1339 | - Fixed smartcard-based authentication in the pluto daemon which was broken by | |
1340 | the ECDSA support introduced with the 4.3.2 release. | |
1341 | ||
cea4bd8f AS |
1342 | - A patch contributed by Heiko Hund fixes mixed IPv6 in IPv4 and vice versa |
1343 | tunnels established with the IKEv1 pluto daemon. | |
1344 | ||
509f70c1 AS |
1345 | - The pluto daemon now uses the libstrongswan x509 plugin for certificates and |
1346 | CRls and the struct id type was replaced by identification_t used by charon | |
1347 | and the libstrongswan library. | |
18060241 | 1348 | |
85af7a89 | 1349 | |
430dd08a AS |
1350 | strongswan-4.3.4 |
1351 | ---------------- | |
1352 | ||
1353 | - IKEv2 charon daemon ported to FreeBSD and Mac OS X. Installation details can | |
1354 | be found on wiki.strongswan.org. | |
1355 | ||
1356 | - ipsec statusall shows the number of bytes transmitted and received over | |
1357 | ESP connections configured by the IKEv2 charon daemon. | |
1358 | ||
1359 | - The IKEv2 charon daemon supports include files in ipsec.secrets. | |
1360 | ||
1361 | ||
1c7f456a AS |
1362 | strongswan-4.3.3 |
1363 | ---------------- | |
1364 | ||
aa74d705 AS |
1365 | - The configuration option --enable-integrity-test plus the strongswan.conf |
1366 | option libstrongswan.integrity_test = yes activate integrity tests | |
1367 | of the IKE daemons charon and pluto, libstrongswan and all loaded | |
1368 | plugins. Thus dynamic library misconfigurations and non-malicious file | |
1369 | manipulations can be reliably detected. | |
1370 | ||
1c7f456a AS |
1371 | - The new default setting libstrongswan.ecp_x_coordinate_only=yes allows |
1372 | IKEv1 interoperability with MS Windows using the ECP DH groups 19 and 20. | |
1373 | ||
1374 | - The IKEv1 pluto daemon now supports the AES-CCM and AES-GCM ESP | |
1375 | authenticated encryption algorithms. | |
1376 | ||
aa74d705 AS |
1377 | - The IKEv1 pluto daemon now supports V4 OpenPGP keys. |
1378 | ||
1379 | - The RDN parser vulnerability discovered by Orange Labs research team | |
1380 | was not completely fixed in version 4.3.2. Some more modifications | |
1381 | had to be applied to the asn1_length() function to make it robust. | |
1382 | ||
1c7f456a | 1383 | |
80c0710c MW |
1384 | strongswan-4.3.2 |
1385 | ---------------- | |
1386 | ||
1387 | - The new gcrypt plugin provides symmetric cipher, hasher, RNG, Diffie-Hellman | |
1388 | and RSA crypto primitives using the LGPL licensed GNU gcrypt library. | |
1389 | ||
1390 | - libstrongswan features an integrated crypto selftest framework for registered | |
1391 | algorithms. The test-vector plugin provides a first set of test vectors and | |
1392 | allows pluto and charon to rely on tested crypto algorithms. | |
1393 | ||
b32af120 AS |
1394 | - pluto can now use all libstrongswan plugins with the exception of x509 and xcbc. |
1395 | Thanks to the openssl plugin, the ECP Diffie-Hellman groups 19, 20, 21, 25, and | |
1396 | 26 as well as ECDSA-256, ECDSA-384, and ECDSA-521 authentication can be used | |
1397 | with IKEv1. | |
126f2130 AS |
1398 | |
1399 | - Applying their fuzzing tool, the Orange Labs vulnerability research team found | |
1400 | another two DoS vulnerabilities, one in the rather old ASN.1 parser of Relative | |
1401 | Distinguished Names (RDNs) and a second one in the conversion of ASN.1 UTCTIME | |
1402 | and GENERALIZEDTIME strings to a time_t value. | |
b6b90b68 | 1403 | |
b32af120 | 1404 | |
3bf7c249 MW |
1405 | strongswan-4.3.1 |
1406 | ---------------- | |
1407 | ||
1408 | - The nm plugin now passes DNS/NBNS server information to NetworkManager, | |
09dbca9f | 1409 | allowing a gateway administrator to set DNS/NBNS configuration on clients |
3bf7c249 MW |
1410 | dynamically. |
1411 | ||
09dbca9f MW |
1412 | - The nm plugin also accepts CA certificates for gateway authentication. If |
1413 | a CA certificate is configured, strongSwan uses the entered gateway address | |
1414 | as its idenitity, requiring the gateways certificate to contain the same as | |
1415 | subjectAltName. This allows a gateway administrator to deploy the same | |
1416 | certificates to Windows 7 and NetworkManager clients. | |
047b2e42 | 1417 | |
050cc582 AS |
1418 | - The command ipsec purgeike deletes IKEv2 SAs that don't have a CHILD SA. |
1419 | The command ipsec down <conn>{n} deletes CHILD SA instance n of connection | |
1420 | <conn> whereas ipsec down <conn>{*} deletes all CHILD SA instances. | |
1421 | The command ipsec down <conn>[n] deletes IKE SA instance n of connection | |
1422 | <conn> plus dependent CHILD SAs whereas ipsec down <conn>[*] deletes all | |
1423 | IKE SA instances of connection <conn>. | |
1424 | ||
09dbca9f | 1425 | - Fixed a regression introduced in 4.3.0 where EAP authentication calculated |
047b2e42 MW |
1426 | the AUTH payload incorrectly. Further, the EAP-MSCHAPv2 MSK key derivation |
1427 | has been updated to be compatible with the Windows 7 Release Candidate. | |
1428 | ||
1429 | - Refactored installation of triggering policies. Routed policies are handled | |
1430 | outside of IKE_SAs to keep them installed in any case. A tunnel gets | |
1431 | established only once, even if initiation is delayed due network outages. | |
1432 | ||
050cc582 AS |
1433 | - Improved the handling of multiple acquire signals triggered by the kernel. |
1434 | ||
1435 | - Fixed two DoS vulnerabilities in the charon daemon that were discovered by | |
1436 | fuzzing techniques: 1) Sending a malformed IKE_SA_INIT request leaved an | |
1437 | incomplete state which caused a null pointer dereference if a subsequent | |
1438 | CREATE_CHILD_SA request was sent. 2) Sending an IKE_AUTH request with either | |
1439 | a missing TSi or TSr payload caused a null pointer derefence because the | |
b6b90b68 | 1440 | checks for TSi and TSr were interchanged. The IKEv2 fuzzer used was |
f3bb1bd0 | 1441 | developed by the Orange Labs vulnerability research team. The tool was |
050cc582 AS |
1442 | initially written by Gabriel Campana and is now maintained by Laurent Butti. |
1443 | ||
047b2e42 MW |
1444 | - Added support for AES counter mode in ESP in IKEv2 using the proposal |
1445 | keywords aes128ctr, aes192ctr and aes256ctr. | |
1446 | ||
d44fd821 | 1447 | - Further progress in refactoring pluto: Use of the curl and ldap plugins |
050cc582 AS |
1448 | for fetching crls and OCSP. Use of the random plugin to get keying material |
1449 | from /dev/random or /dev/urandom. Use of the openssl plugin as an alternative | |
d44fd821 | 1450 | to the aes, des, sha1, sha2, and md5 plugins. The blowfish, twofish, and |
050cc582 | 1451 | serpent encryption plugins are now optional and are not enabled by default. |
d44fd821 AS |
1452 | |
1453 | ||
247e665a AS |
1454 | strongswan-4.3.0 |
1455 | ---------------- | |
1456 | ||
81fc8e5f MW |
1457 | - Support for the IKEv2 Multiple Authentication Exchanges extension (RFC4739). |
1458 | Initiators and responders can use several authentication rounds (e.g. RSA | |
1459 | followed by EAP) to authenticate. The new ipsec.conf leftauth/rightauth and | |
1460 | leftauth2/rightauth2 parameters define own authentication rounds or setup | |
1461 | constraints for the remote peer. See the ipsec.conf man page for more detials. | |
1462 | ||
1463 | - If glibc printf hooks (register_printf_function) are not available, | |
1464 | strongSwan can use the vstr string library to run on non-glibc systems. | |
1465 | ||
558c89e7 AS |
1466 | - The IKEv2 charon daemon can now configure the ESP CAMELLIA-CBC cipher |

1484 | - A vulnerability in the Dead Peer Detection (RFC 3706) code was found by |
1485 | Gerd v. Egidy <gerd.von.egidy@intra2net.com> of Intra2net AG affecting | |
1486 | all Openswan and strongSwan releases. A malicious (or expired ISAKMP) | |
1487 | R_U_THERE or R_U_THERE_ACK Dead Peer Detection packet can cause the | |
1488 | pluto IKE daemon to crash and restart. No authentication or encryption | |
1489 | is required to trigger this bug. One spoofed UDP packet can cause the | |
1490 | pluto IKE daemon to restart and be unresponsive for a few seconds while | |
1491 | restarting. This DPD null state vulnerability has been officially | |
1492 | registered as CVE-2009-0790 and is fixed by this release. | |
1493 | ||
22180558 AS |
1494 | - ASN.1 to time_t conversion caused a time wrap-around for |
1495 | dates after Jan 18 03:14:07 UTC 2038 on 32-bit platforms. | |
1496 | As a workaround such dates are set to the maximum representable | |

1543 | strongswan-4.2.10 |
1544 | ----------------- | |
1545 | ||
1546 | - Several performance improvements to handle thousands of tunnels with almost | |
1547 | linear upscaling. All relevant data structures have been replaced by faster | |
1548 | counterparts with better lookup times. | |
1549 | ||
1550 | - Better parallelization to run charon on multiple cores. Due to improved | |
1551 | ressource locking and other optimizations the daemon can take full | |
1552 | advantage of 16 or even more cores. | |
1553 | ||
1554 | - The load-tester plugin can use a NULL Diffie-Hellman group and simulate | |
1555 | unique identities and certificates by signing peer certificates using a CA | |
1556 | on the fly. | |
1557 | ||
1558 | - The redesigned stroke in-memory IP pool handles leases. The "ipsec leases" | |
1559 | command queries assigned leases. | |
1560 | ||
1561 | - Added support for smartcards in charon by using the ENGINE API provided by | |
1562 | OpenSSL, based on patches by Michael Roßberg. | |
1563 | ||
1564 | - The Padlock plugin supports the hardware RNG found on VIA CPUs to provide a | |
1565 | reliable source of randomness. | |

1571 | syslog facilities or to files using fine-grained log levels for each target. | |
73937bd8 MW |
1572 | |
1573 | - Load testing plugin to do stress testing of the IKEv2 daemon against self | |
1574 | or another host. Found and fixed issues during tests in the multi-threaded | |
1575 | use of the OpenSSL plugin. | |
1576 | ||
1577 | - Added profiling code to synchronization primitives to find bottlenecks if | |
7bdc931e | 1578 | running on multiple cores. Found and fixed an issue where parts of the |
73937bd8 MW |
1579 | Diffie-Hellman calculation acquired an exclusive lock. This greatly improves |
1580 | parallelization to multiple cores. | |
1581 | ||
509e07c5 AS |
1582 | - updown script invocation has been separated into a plugin of its own to |
1583 | further slim down the daemon core. | |
73937bd8 | 1584 | |
509e07c5 | 1585 | - Separated IKE_SA/CHILD_SA key derivation process into a closed system, |
7bdc931e | 1586 | allowing future implementations to use a secured environment in e.g. kernel |
73937bd8 MW |
1587 | memory or hardware. |
1588 | ||
509e07c5 AS |
1589 | - The kernel interface of charon has been modularized. XFRM NETLINK (default) |
1590 | and PFKEY (--enable-kernel-pfkey) interface plugins for the native IPsec | |
1591 | stack of the Linux 2.6 kernel as well as a PFKEY interface for the KLIPS | |
1592 | IPsec stack (--enable-kernel-klips) are provided. | |
1593 | ||
1594 | - Basic Mobile IPv6 support has been introduced, securing Binding Update | |
1595 | messages as well as tunneled traffic between Mobile Node and Home Agent. | |
1596 | The installpolicy=no option allows peaceful cooperation with a dominant | |
1597 | mip6d daemon and the new type=transport_proxy implements the special MIPv6 | |
1598 | IPsec transport proxy mode where the IKEv2 daemon uses the Care-of-Address | |
f3bb1bd0 | 1599 | but the IPsec SA is set up for the Home Address. |
7bdc931e | 1600 | |
4dc0dce8 AS |
1601 | - Implemented migration of Mobile IPv6 connections using the KMADDRESS |
1602 | field contained in XFRM_MSG_MIGRATE messages sent by the mip6d daemon | |
1603 | via the Linux 2.6.28 (or appropriately patched) kernel. | |

1611 | lists the available raw public keys via the stroke interface. | |
1612 | ||
4f0241e6 MW |
1613 | - Several MOBIKE improvements: Detect changes in NAT mappings in DPD exchanges, |
1614 | handle events if kernel detects NAT mapping changes in UDP-encapsulated | |
1615 | ESP packets (requires kernel patch), reuse old addesses in MOBIKE updates as | |
1616 | long as possible and other fixes. | |
1617 | ||
5dadb16e AS |
1618 | - Fixed a bug in addr_in_subnet() which caused insertion of wrong source |
1619 | routes for destination subnets having netwmasks not being a multiple of 8 bits. | |

1623 | strongswan-4.2.7 |
1624 | ---------------- | |
1625 | ||
b37cda82 AS |
1626 | - Fixed a Denial-of-Service vulnerability where an IKE_SA_INIT message with |
1627 | a KE payload containing zeroes only can cause a crash of the IKEv2 charon | |
1628 | daemon due to a NULL pointer returned by the mpz_export() function of the | |
1629 | GNU Multiprecision Library (GMP). Thanks go to Mu Dynamics Research Labs | |
b6b90b68 | 1630 | for making us aware of this problem. |
b37cda82 | 1631 | |
b6b90b68 | 1632 | - The new agent plugin provides a private key implementation on top of an |

1633 | ssh-agent. |
1634 | ||
1635 | - The NetworkManager plugin has been extended to support certificate client | |
b1f47854 | 1636 | authentication using RSA keys loaded from a file or using ssh-agent. |
e376d75f MW |
1637 | |
1638 | - Daemon capability dropping has been ported to libcap and must be enabled | |
1639 | explicitly --with-capabilities=libcap. Future version will support the | |
1640 | newer libcap2 library. | |
1641 | ||

1648 | ||
609166f4 MW |
1649 | - A NetworkManager plugin allows GUI-based configuration of road-warrior |
1650 | clients in a simple way. It features X509 based gateway authentication | |
1651 | and EAP client authentication, tunnel setup/teardown and storing passwords | |
1652 | in the Gnome Keyring. | |
1653 | ||
1654 | - A new EAP-GTC plugin implements draft-sheffer-ikev2-gtc-00.txt and allows | |
1655 | username/password authentication against any PAM service on the gateway. | |
b6b90b68 | 1656 | The new EAP method interacts nicely with the NetworkManager plugin and allows |
609166f4 MW |
1657 | client authentication against e.g. LDAP. |
1658 | ||
1659 | - Improved support for the EAP-Identity method. The new ipsec.conf eap_identity | |
1660 | parameter defines an additional identity to pass to the server in EAP | |
1661 | authentication. | |
1662 | ||
9f9d6ece AS |
1663 | - The "ipsec statusall" command now lists CA restrictions, EAP |
1664 | authentication types and EAP identities. | |

8124e491 AS |
1677 | |
1678 | - Improved the performance of the SQL-based virtual IP address pool | |
1679 | by introducing an additional addresses table. The leases table | |
1680 | storing only history information has become optional and can be | |
1681 | disabled by setting charon.plugins.sql.lease_history = no in | |
1682 | strongswan.conf. | |
1683 | ||
eb0cc338 | 1684 | - The XFRM_STATE_AF_UNSPEC flag added to xfrm.h allows IPv4-over-IPv6 |
de5f70e7 | 1685 | and IPv6-over-IPv4 tunnels with the 2.6.26 and later Linux kernels. |
eb0cc338 | 1686 | |

1728 | strongswan-4.2.2 |
1729 | ---------------- | |
1730 | ||
a57cd446 AS |
1731 | - Plugins for libstrongswan and charon can optionally be loaded according |
1732 | to a configuration in strongswan.conf. Most components provide a | |
7f491111 | 1733 | "load = " option followed by a space separated list of plugins to load. |
a57cd446 AS |
1734 | This allows e.g. the fallback from a hardware crypto accelerator to |
1735 | to software-based crypto plugins. | |
7f491111 MW |
1736 | |
1737 | - Charons SQL plugin has been extended by a virtual IP address pool. | |
a57cd446 AS |
1738 | Configurations with a rightsourceip=%poolname setting query a SQLite or |
1739 | MySQL database for leases. The "ipsec pool" command helps in administrating | |
1740 | the pool database. See ipsec pool --help for the available options | |
1741 | ||
1742 | - The Authenticated Encryption Algorithms AES-CCM-8/12/16 and AES-GCM-8/12/16 | |
b6b90b68 | 1743 | for ESP are now supported starting with the Linux 2.6.25 kernel. The |
a57cd446 AS |

1747 | strongswan-4.2.1 |
1748 | ---------------- | |
1749 | ||
c306dfb1 | 1750 | - Support for "Hash and URL" encoded certificate payloads has been implemented |
b1f8fc0c TB |
1751 | in the IKEv2 daemon charon. Using the "certuribase" option of a CA section |
1752 | allows to assign a base URL to all certificates issued by the specified CA. | |
1753 | The final URL is then built by concatenating that base and the hex encoded | |
1754 | SHA1 hash of the DER encoded certificate. Note that this feature is disabled | |
1755 | by default and must be enabled using the option "charon.hash_and_url". | |
5c5d67d6 | 1756 | |
58caabf7 MW |
1757 | - The IKEv2 daemon charon now supports the "uniqueids" option to close multiple |
1758 | IKE_SAs with the same peer. The option value "keep" prefers existing | |
1759 | connection setups over new ones, where the value "replace" replaces existing | |
1760 | connections. | |
b6b90b68 | 1761 | |
f3bb1bd0 | 1762 | - The crypto factory in libstrongswan additionally supports random number |
58caabf7 | 1763 | generators, plugins may provide other sources of randomness. The default |
c306dfb1 | 1764 | plugin reads raw random data from /dev/(u)random. |
58caabf7 | 1765 | |
b6b90b68 | 1766 | - Extended the credential framework by a caching option to allow plugins |
58caabf7 | 1767 | persistent caching of fetched credentials. The "cachecrl" option has been |
c306dfb1 | 1768 | re-implemented. |
58caabf7 MW |
1769 | |
1770 | - The new trustchain verification introduced in 4.2.0 has been parallelized. | |
1771 | Threads fetching CRL or OCSP information no longer block other threads. | |
5c5d67d6 | 1772 | |
58caabf7 MW |
1773 | - A new IKEv2 configuration attribute framework has been introduced allowing |
1774 | plugins to provide virtual IP addresses, and in the future, other | |
1775 | configuration attribute services (e.g. DNS/WINS servers). | |
5c5d67d6 | 1776 | |
466abb49 | 1777 | - The stroke plugin has been extended to provide virtual IP addresses from |
58caabf7 MW |
1778 | a pool defined in ipsec.conf. The "rightsourceip" parameter now accepts |
1779 | address pools in CIDR notation (e.g. 10.1.1.0/24). The parameter also accepts | |
1780 | the value "%poolname", where "poolname" identifies a pool provided by a | |
466abb49 | 1781 | separate plugin. |
58caabf7 | 1782 | |
c306dfb1 | 1783 | - Fixed compilation on uClibc and a couple of other minor bugs. |
58caabf7 | 1784 | |
c306dfb1 | 1785 | - Set DPD defaults in ipsec starter to dpd_delay=30s and dpd_timeout=150s. |
466abb49 AS |
1786 | |
1787 | - The IKEv1 pluto daemon now supports the ESP encryption algorithm CAMELLIA | |
c306dfb1 | 1788 | with key lengths of 128, 192, and 256 bits, as well as the authentication |
466abb49 AS |
1789 | algorithm AES_XCBC_MAC. Configuration example: esp=camellia192-aesxcbc. |

16f5dacd MW |
1795 | - libstrongswan has been modularized to attach crypto algorithms, |
1796 | credential implementations (keys, certificates) and fetchers dynamically | |
1797 | through plugins. Existing code has been ported to plugins: | |
1798 | - RSA/Diffie-Hellman implementation using the GNU Multi Precision library | |
1799 | - X509 certificate system supporting CRLs, OCSP and attribute certificates | |
1800 | - Multiple plugins providing crypto algorithms in software | |
1801 | - CURL and OpenLDAP fetcher | |
a11ea97d | 1802 | |
16f5dacd MW |
1803 | - libstrongswan gained a relational database API which uses pluggable database |
1804 | providers. Plugins for MySQL and SQLite are available. | |
1805 | ||
1806 | - The IKEv2 keying daemon charon is more extensible. Generic plugins may provide | |
1807 | connection configuration, credentials and EAP methods or control the daemon. | |
1808 | Existing code has been ported to plugins: | |
1809 | - EAP-AKA, EAP-SIM, EAP-MD5 and EAP-Identity | |
1810 | - stroke configuration, credential and control (compatible to pluto) | |
1811 | - XML bases management protocol to control and query the daemon | |
1812 | The following new plugins are available: | |
1813 | - An experimental SQL configuration, credential and logging plugin on | |
1814 | top of either MySQL or SQLite | |
1815 | - A unit testing plugin to run tests at daemon startup | |
1816 | ||
1817 | - The authentication and credential framework in charon has been heavily | |
1818 | refactored to support modular credential providers, proper | |
1819 | CERTREQ/CERT payload exchanges and extensible authorization rules. | |
1820 | ||
b6b90b68 | 1821 | - The framework of strongSwan Manager has envolved to the web application |
16f5dacd MW |
1822 | framework libfast (FastCGI Application Server w/ Templates) and is usable |
1823 | by other applications. | |

b6b90b68 | 1834 | caused an INVALID_SYNTAX error on PowerPC platforms. |
fb6d76cd | 1835 | |
e6b50b3f AS |
1836 | - Implemented IKEv2 EAP-SIM server and client test modules that use |
1837 | triplets stored in a file. For details on the configuration see | |
1838 | the scenario 'ikev2/rw-eap-sim-rsa'. | |

1841 | strongswan-4.1.10 |
1842 | ----------------- | |
1843 | ||
1844 | - Fixed error in the ordering of the certinfo_t records in the ocsp cache that | |
b6b90b68 | 1845 | caused multiple entries of the same serial number to be created. |
83e0d841 | 1846 | |
fdc7c943 MW |
1847 | - Implementation of a simple EAP-MD5 module which provides CHAP |
1848 | authentication. This may be interesting in conjunction with certificate | |
1849 | based server authentication, as weak passwords can't be brute forced | |
1850 | (in contradiction to traditional IKEv2 PSK). | |
1851 | ||
1852 | - A complete software based implementation of EAP-AKA, using algorithms | |
1853 | specified in 3GPP2 (S.S0055). This implementation does not use an USIM, | |
1854 | but reads the secrets from ipsec.secrets. Make sure to read eap_aka.h | |
1855 | before using it. | |
1856 | ||
1857 | - Support for vendor specific EAP methods using Expanded EAP types. The | |
b6b90b68 | 1858 | interface to EAP modules has been slightly changed, so make sure to |
fdc7c943 | 1859 | check the changes if you're already rolling your own modules. |

1862 | strongswan-4.1.9 |
1863 | ---------------- | |
1864 | ||
800b3356 AS |
1865 | - The default _updown script now dynamically inserts and removes ip6tables |
1866 | firewall rules if leftfirewall=yes is set in IPv6 connections. New IPv6 | |
1867 | net-net and roadwarrior (PSK/RSA) scenarios for both IKEv1 and IKEV2 were | |
1868 | added. | |
5076770c | 1869 | |
6f274c2a MW |
1870 | - Implemented RFC4478 repeated authentication to force EAP/Virtual-IP clients |
1871 | to reestablish an IKE_SA within a given timeframe. | |
1872 | ||
1873 | - strongSwan Manager supports configuration listing, initiation and termination | |
1874 | of IKE and CHILD_SAs. | |
1875 | ||
1876 | - Fixes and improvements to multithreading code. | |
1877 | ||
8b678ad4 | 1878 | - IKEv2 plugins have been renamed to libcharon-* to avoid naming conflicts. |
b6b90b68 | 1879 | Make sure to remove the old plugins in $libexecdir/ipsec, otherwise they get |
8b678ad4 | 1880 | loaded twice. |

1883 | strongswan-4.1.8 |
1884 | ---------------- | |
1885 | ||
5076770c | 1886 | - Removed recursive pthread mutexes since uClibc doesn't support them. |
b82e8231 AS |
1887 | |

a4a3632c AS |
1889 | strongswan-4.1.7 |
1890 | ---------------- | |
1891 | ||
1892 | - In NAT traversal situations and multiple queued Quick Modes, | |
1893 | those pending connections inserted by auto=start after the | |
1894 | port floating from 500 to 4500 were erronously deleted. | |
1895 | ||
6e193274 | 1896 | - Added a "forceencaps" connection parameter to enforce UDP encapsulation |
078b6008 | 1897 | to surmount restrictive firewalls. NAT detection payloads are faked to |
6e193274 MW |
1898 | simulate a NAT situation and trick the other peer into NAT mode (IKEv2 only). |
1899 | ||
1900 | - Preview of strongSwan Manager, a web based configuration and monitoring | |
1901 | application. It uses a new XML control interface to query the IKEv2 daemon | |
64d24679 | 1902 | (see http://wiki.strongswan.org/wiki/Manager). |
6e193274 MW |
1903 | |
1904 | - Experimental SQLite configuration backend which will provide the configuration | |
1905 | interface for strongSwan Manager in future releases. | |
1906 | ||
1907 | - Further improvements to MOBIKE support. | |
1908 | ||
a4a3632c | 1909 | |
3dcf9dbd AS |
1910 | strongswan-4.1.6 |
1911 | ---------------- | |
1912 | ||
3eac4dfd AS |
1913 | - Since some third party IKEv2 implementations run into |
1914 | problems with strongSwan announcing MOBIKE capability per | |
1915 | default, MOBIKE can be disabled on a per-connection-basis | |
1916 | using the mobike=no option. Whereas mobike=no disables the | |
1917 | sending of the MOBIKE_SUPPORTED notification and the floating | |
1918 | to UDP port 4500 with the IKE_AUTH request even if no NAT | |
1919 | situation has been detected, strongSwan will still support | |
1920 | MOBIKE acting as a responder. | |
1921 | ||
1922 | - the default ipsec routing table plus its corresponding priority | |
1923 | used for inserting source routes has been changed from 100 to 220. | |
1924 | It can be configured using the --with-ipsec-routing-table and | |
b6b90b68 MW |
1925 | --with-ipsec-routing-table-prio options. |
1926 | ||
bdc0b55b AS |
1927 | - the --enable-integrity-test configure option tests the |
1928 | integrity of the libstrongswan crypto code during the charon | |
1929 | startup. | |
b6b90b68 | 1930 | |
3eac4dfd AS |
1931 | - the --disable-xauth-vid configure option disables the sending |
1932 | of the XAUTH vendor ID. This can be used as a workaround when | |
1933 | interoperating with some Windows VPN clients that get into | |
1934 | trouble upon reception of an XAUTH VID without eXtended | |
1935 | AUTHentication having been configured. | |
b6b90b68 | 1936 | |
f872f9d1 AS |
1937 | - ipsec stroke now supports the rereadsecrets, rereadaacerts, |
1938 | rereadacerts, and listacerts options. | |
3dcf9dbd AS |
1939 | |
1940 | ||
7ad634a2 AS |
1941 | strongswan-4.1.5 |
1942 | ---------------- | |
1943 | ||
1944 | - If a DNS lookup failure occurs when resolving right=%<FQDN> | |
1945 | or right=<FQDN> combined with rightallowany=yes then the | |
1946 | connection is not updated by ipsec starter thus preventing | |
1947 | the disruption of an active IPsec connection. Only if the DNS | |
1948 | lookup successfully returns with a changed IP address the | |
1949 | corresponding connection definition is updated. | |
1950 | ||
8f5b363c MW |
1951 | - Routes installed by the keying daemons are now in a separate |
1952 | routing table with the ID 100 to avoid conflicts with the main | |
1953 | table. Route lookup for IKEv2 traffic is done in userspace to ignore | |
1954 | routes installed for IPsec, as IKE traffic shouldn't get encapsulated. | |
1955 | ||
7ad634a2 | 1956 | |
e93c68ba AS |
1957 | strongswan-4.1.4 |
1958 | ---------------- | |
1959 | ||
1960 | - The pluto IKEv1 daemon now exhibits the same behaviour as its | |
1961 | IKEv2 companion charon by inserting an explicit route via the | |
1962 | _updown script only if a sourceip exists. This is admissible | |
1963 | since routing through the IPsec tunnel is handled automatically | |
b7af55ac AS |
1964 | by NETKEY's IPsec policies. As a consequence the left|rightnexthop |
1965 | parameter is not required any more. | |
078ce348 AS |
1966 | |
1967 | - The new IKEv1 parameter right|leftallowany parameters helps to handle | |
1968 | the case where both peers possess dynamic IP addresses that are | |
1969 | usually resolved using DynDNS or a similar service. The configuration | |
1970 | ||
1971 | right=peer.foo.bar | |
1972 | rightallowany=yes | |
1973 | ||
1974 | can be used by the initiator to start up a connection to a peer | |
1975 | by resolving peer.foo.bar into the currently allocated IP address. | |
1976 | Thanks to the rightallowany flag the connection behaves later on | |
1977 | as | |
1978 | ||
1979 | right=%any | |
1980 | ||
1981 | so that the peer can rekey the connection as an initiator when his | |
1fbdab85 AS |
1982 | IP address changes. An alternative notation is |
1983 | ||
1984 | right=%peer.foo.bar | |
1985 | ||
1986 | which will implicitly set rightallowany=yes. | |
1987 | ||
1988 | - ipsec starter now fails more gracefully in the presence of parsing | |
1989 | errors. Flawed ca and conn section are discarded and pluto is started | |
1990 | if non-fatal errors only were encountered. If right=%peer.foo.bar | |
1991 | cannot be resolved by DNS then right=%any will be used so that passive | |
1992 | connections as a responder are still possible. | |
078ce348 | 1993 | |
a0a0bdd7 AS |
1994 | - The new pkcs11initargs parameter that can be placed in the |
1995 | setup config section of /etc/ipsec.conf allows the definition | |
1996 | of an argument string that is used with the PKCS#11 C_Initialize() | |
1997 | function. This non-standard feature is required by the NSS softoken | |
1998 | library. This patch was contributed by Robert Varga. | |
b6b90b68 | 1999 | |
a0a0bdd7 AS |
2000 | - Fixed a bug in ipsec starter introduced by strongswan-2.8.5 |
2001 | which caused a segmentation fault in the presence of unknown | |
2002 | or misspelt keywords in ipsec.conf. This bug fix was contributed | |
2003 | by Robert Varga. | |
2004 | ||
e3606f2b MW |
2005 | - Partial support for MOBIKE in IKEv2. The initiator acts on interface/ |
2006 | address configuration changes and updates IKE and IPsec SAs dynamically. | |
e93c68ba | 2007 | |
06651827 | 2008 | |
a3354a69 AS |
2009 | strongswan-4.1.3 |
2010 | ---------------- | |
2011 | ||
b6b90b68 | 2012 | - IKEv2 peer configuration selection now can be based on a given |
35d4809c AS |
2013 | certification authority using the rightca= statement. |
2014 | ||
2015 | - IKEv2 authentication based on RSA signatures now can handle multiple | |
41e16cf4 AS |
2016 | certificates issued for a given peer ID. This allows a smooth transition |
2017 | in the case of a peer certificate renewal. | |
a3354a69 | 2018 | |
998ca0ea MW |
2019 | - IKEv2: Support for requesting a specific virtual IP using leftsourceip on the |
2020 | client and returning requested virtual IPs using rightsourceip=%config | |
2021 | on the server. If the server does not support configuration payloads, the | |
2022 | client enforces its leftsourceip parameter. | |
2023 | ||
2024 | - The ./configure options --with-uid/--with-gid allow pluto and charon | |
2025 | to drop their privileges to a minimum and change to an other UID/GID. This | |
2026 | improves the systems security, as a possible intruder may only get the | |
2027 | CAP_NET_ADMIN capability. | |
2028 | ||
b6b90b68 | 2029 | - Further modularization of charon: Pluggable control interface and |
998ca0ea MW |
2030 | configuration backend modules provide extensibility. The control interface |
2031 | for stroke is included, and further interfaces using DBUS (NetworkManager) | |
2032 | or XML are on the way. A backend for storing configurations in the daemon | |
b6b90b68 | 2033 | is provided and more advanced backends (using e.g. a database) are trivial |
998ca0ea | 2034 | to implement. |
a3354a69 | 2035 | |
f3bb1bd0 | 2036 | - Fixed a compilation failure in libfreeswan occurring with Linux kernel |
41e16cf4 AS |
2037 | headers > 2.6.17. |
2038 | ||
2039 | ||
8ea7b96f AS |
2040 | strongswan-4.1.2 |
2041 | ---------------- | |
2042 | ||
e23d98a7 | 2043 | - Support for an additional Diffie-Hellman exchange when creating/rekeying |
37fb0355 MW |
2044 | a CHILD_SA in IKEv2 (PFS). PFS is enabled when the proposal contains a |
2045 | DH group (e.g. "esp=aes128-sha1-modp1536"). Further, DH group negotiation | |
2046 | is implemented properly for rekeying. | |
2047 | ||
2048 | - Support for the AES-XCBC-96 MAC algorithm for IPsec SAs when using IKEv2 | |
2049 | (requires linux >= 2.6.20). It is enabled using e.g. "esp=aes256-aesxcbc". | |
2050 | ||
d931f465 MW |
2051 | - Working IPv4-in-IPv6 and IPv6-in-IPv4 tunnels for linux >= 2.6.21. |
2052 | ||
37fb0355 MW |
2053 | - Added support for EAP modules which do not establish an MSK. |
2054 | ||
dfbe2a0f | 2055 | - Removed the dependencies from the /usr/include/linux/ headers by |
9f78f957 | 2056 | including xfrm.h, ipsec.h, and pfkeyv2.h in the distribution. |
b6b90b68 | 2057 | |
9f78f957 AS |
2058 | - crlNumber is now listed by ipsec listcrls |
2059 | ||
8ea7b96f AS |
2060 | - The xauth_modules.verify_secret() function now passes the |
2061 | connection name. | |
2062 | ||
e23d98a7 | 2063 | |
ed284399 MW |
2064 | strongswan-4.1.1 |
2065 | ---------------- | |
2066 | ||
2067 | - Server side cookie support. If to may IKE_SAs are in CONNECTING state, | |
2068 | cookies are enabled and protect against DoS attacks with faked source | |
2069 | addresses. Number of IKE_SAs in CONNECTING state is also limited per | |
2070 | peer address to avoid resource exhaustion. IKE_SA_INIT messages are | |
2071 | compared to properly detect retransmissions and incoming retransmits are | |
2072 | detected even if the IKE_SA is blocked (e.g. doing OCSP fetches). | |
2073 | ||
db88e37d AS |
2074 | - The IKEv2 daemon charon now supports dynamic http- and ldap-based CRL |
2075 | fetching enabled by crlcheckinterval > 0 and caching fetched CRLs | |
2076 | enabled by cachecrls=yes. | |
2077 | ||
3b4f7d92 AS |
2078 | - Added the configuration options --enable-nat-transport which enables |
2079 | the potentially insecure NAT traversal for IPsec transport mode and | |
2080 | --disable-vendor-id which disables the sending of the strongSwan | |
2081 | vendor ID. | |
2082 | ||
2083 | - Fixed a long-standing bug in the pluto IKEv1 daemon which caused | |
2084 | a segmentation fault if a malformed payload was detected in the | |
2085 | IKE MR2 message and pluto tried to send an encrypted notification | |
2086 | message. | |
2087 | ||
46b9ff68 AS |
2088 | - Added the NATT_IETF_02_N Vendor ID in order to support IKEv1 connections |
2089 | with Windows 2003 Server which uses a wrong VID hash. | |
2090 | ||
3b4f7d92 | 2091 | |
34bbd0c3 | 2092 | strongswan-4.1.0 |
cd3958f8 AS |
2093 | ---------------- |
2094 | ||
2095 | - Support of SHA2_384 hash function for protecting IKEv1 | |
2096 | negotiations and support of SHA2 signatures in X.509 certificates. | |
2097 | ||
2098 | - Fixed a serious bug in the computation of the SHA2-512 HMAC | |
2099 | function. Introduced automatic self-test of all IKEv1 hash | |
2100 | and hmac functions during pluto startup. Failure of a self-test | |
2101 | currently issues a warning only but does not exit pluto [yet]. | |
2102 | ||
9b45443d MW |
2103 | - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2. |
2104 | ||
c5d0fbb6 | 2105 | - Full support of CA information sections. ipsec listcainfos |
b6b90b68 | 2106 | now shows all collected crlDistributionPoints and OCSP |
c5d0fbb6 AS |
2107 | accessLocations. |
2108 | ||
69ed04bf AS |
2109 | - Support of the Online Certificate Status Protocol (OCSP) for IKEv2. |
2110 | This feature requires the HTTP fetching capabilities of the libcurl | |
2111 | library which must be enabled by setting the --enable-http configure | |
2112 | option. | |
2113 | ||
9b45443d MW |
2114 | - Refactored core of the IKEv2 message processing code, allowing better |
2115 | code reuse and separation. | |
2116 | ||
2117 | - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration | |
2118 | payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted | |
2119 | by the requestor and installed in a resolv.conf file. | |
2120 | ||
2121 | - The IKEv2 daemon charon installs a route for each IPsec policy to use | |
2122 | the correct source address even if an application does not explicitly | |
2123 | specify it. | |
2124 | ||
2125 | - Integrated the EAP framework into charon which loads pluggable EAP library | |
2126 | modules. The ipsec.conf parameter authby=eap initiates EAP authentication | |
2127 | on the client side, while the "eap" parameter on the server side defines | |
2128 | the EAP method to use for client authentication. | |
2129 | A generic client side EAP-Identity module and an EAP-SIM authentication | |
2130 | module using a third party card reader implementation are included. | |
2131 | ||
2132 | - Added client side support for cookies. | |
2133 | ||
2134 | - Integrated the fixes done at the IKEv2 interoperability bakeoff, including | |
2135 | strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor | |
2136 | fixes to enhance interoperability with other implementations. | |

2139 | strongswan-4.0.7 |
2140 | ---------------- | |
2141 | ||
6fdf5f44 AS |
2142 | - strongSwan now interoperates with the NCP Secure Entry Client, |
2143 | the Shrew Soft VPN Client, and the Cisco VPN client, doing both | |
2144 | XAUTH and Mode Config. | |
1c266d7d AS |
2145 | |
2146 | - UNITY attributes are now recognized and UNITY_BANNER is set | |

2b4405a3 MW |
2150 | strongswan-4.0.6 |
2151 | ---------------- | |
2152 | ||
e38a15d4 AS |
2153 | - IKEv1: Support for extended authentication (XAUTH) in combination |
2154 | with ISAKMP Main Mode RSA or PSK authentication. Both client and | |
2155 | server side were implemented. Handling of user credentials can | |
2156 | be done by a run-time loadable XAUTH module. By default user | |
b6b90b68 MW |
2157 | credentials are stored in ipsec.secrets. |
2158 | ||
2b4405a3 MW |
2159 | - IKEv2: Support for reauthentication when rekeying |
2160 | ||
5903179b | 2161 | - IKEv2: Support for transport mode |
af87afed | 2162 | |
5903179b | 2163 | - fixed a lot of bugs related to byte order |
2b4405a3 | 2164 | |

0cd645d2 AS |
2168 | strongswan-4.0.5 |
2169 | ---------------- | |
2170 | ||
2171 | - IKEv1: Implementation of ModeConfig push mode via the new connection | |
2172 | keyword modeconfig=push allows interoperability with Cisco VPN gateways. | |
2173 | ||
2174 | - IKEv1: The command ipsec statusall now shows "DPD active" for all | |
2175 | ISAKMP SAs that are under active Dead Peer Detection control. | |
2176 | ||
2177 | - IKEv2: Charon's logging and debugging framework has been completely rewritten. | |
2178 | Instead of logger, special printf() functions are used to directly | |
2179 | print objects like hosts (%H) identifications (%D), certificates (%Q), | |
2180 | etc. The number of debugging levels have been reduced to: | |
03bf883d | 2181 | |
0cd645d2 | 2182 | 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private) |
03bf883d | 2183 | |
0cd645d2 AS |
2184 | The debugging levels can either be specified statically in ipsec.conf as |
2185 | ||

48dc3934 MW |
2194 | strongswan-4.0.4 |
2195 | ---------------- | |
2196 | ||
2197 | - Implemented full support for IPv6-in-IPv6 tunnels. | |
2198 | ||
2199 | - Added configuration options for dead peer detection in IKEv2. dpd_action | |
2200 | types "clear", "hold" and "restart" are supported. The dpd_timeout | |
2201 | value is not used, as the normal retransmission policy applies to | |
2202 | detect dead peers. The dpd_delay parameter enables sending of empty | |
2203 | informational message to detect dead peers in case of inactivity. | |
2204 | ||
2205 | - Added support for preshared keys in IKEv2. PSK keys configured in | |
2206 | ipsec.secrets are loaded. The authby parameter specifies the authentication | |
2207 | method to authentificate ourself, the other peer may use PSK or RSA. | |
2208 | ||
2209 | - Changed retransmission policy to respect the keyingtries parameter. | |
2210 | ||
112ad7c3 AS |
2211 | - Added private key decryption. PEM keys encrypted with AES-128/192/256 |
2212 | or 3DES are supported. | |
48dc3934 MW |
2213 | |
2214 | - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to | |
2215 | encrypt IKE traffic. | |
2216 | ||
2217 | - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates | |
2218 | signed with such a hash algorithm. | |
2219 | ||
2220 | - Added initial support for updown scripts. The actions up-host/client and | |
2221 | down-host/client are executed. The leftfirewall=yes parameter | |
2222 | uses the default updown script to insert dynamic firewall rules, a custom | |
2223 | updown script may be specified with the leftupdown parameter. | |
2224 | ||
2225 | ||
a1310b6b MW |
2226 | strongswan-4.0.3 |
2227 | ---------------- | |
2228 | ||
2229 | - Added support for the auto=route ipsec.conf parameter and the | |
b6b90b68 MW |
2230 | ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and |
2231 | CHILD_SAs dynamically on demand when traffic is detected by the | |
a1310b6b MW |
2232 | kernel. |
2233 | ||
2234 | - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter. | |
2235 | As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only | |
2236 | new keys are generated using perfect forward secrecy. An optional flag | |
2237 | which enforces reauthentication will be implemented later. | |
2238 | ||
b425d998 AS |
2239 | - "sha" and "sha1" are now treated as synonyms in the ike= and esp= |
2240 | algorithm configuration statements. | |
2241 | ||
2242 | ||
bf4df11f AS |
2243 | strongswan-4.0.2 |
2244 | ---------------- | |
2245 | ||
623d3dcf AS |
2246 | - Full X.509 certificate trust chain verification has been implemented. |
2247 | End entity certificates can be exchanged via CERT payloads. The current | |
2248 | default is leftsendcert=always, since CERTREQ payloads are not supported | |
2249 | yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls. | |
efa40c11 | 2250 | |
b6b90b68 | 2251 | - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2 |
efa40c11 | 2252 | would offer more possibilities for traffic selection, but the Linux kernel |
b6b90b68 | 2253 | currently does not support it. That's why we stick with these simple |
efa40c11 MW |
2254 | ipsec.conf rules for now. |
2255 | ||
623d3dcf AS |
2256 | - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no |
2257 | IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear, | |
2258 | dpddelay=60s). | |
2259 | ||
efa40c11 MW |
2260 | - Initial NAT traversal support in IKEv2. Charon includes NAT detection |
2261 | notify payloads to detect NAT routers between the peers. It switches | |
2262 | to port 4500, uses UDP encapsulated ESP packets, handles peer address | |
2263 | changes gracefully and sends keep alive message periodically. | |
2264 | ||
b6b90b68 MW |
2265 | - Reimplemented IKE_SA state machine for charon, which allows simultaneous |
2266 | rekeying, more shared code, cleaner design, proper retransmission | |
efa40c11 MW |
2267 | and a more extensible code base. |
2268 | ||
cfd8b27f AS |
2269 | - The mixed PSK/RSA roadwarrior detection capability introduced by the |
2270 | strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal | |
2271 | payloads by the responder right before any defined IKE Main Mode state had | |
2272 | been established. Although any form of bad proposal syntax was being correctly | |
2273 | detected by the payload parser, the subsequent error handler didn't check | |
2274 | the state pointer before logging current state information, causing an | |
2275 | immediate crash of the pluto keying daemon due to a NULL pointer. | |
2276 | ||
bf4df11f | 2277 | |
7e81e975 MW |
2278 | strongswan-4.0.1 |
2279 | ---------------- | |
2280 | ||
b6b90b68 | 2281 | - Added algorithm selection to charon: New default algorithms for |
c15c3d4b MW |
2282 | ike=aes128-sha-modp2048, as both daemons support it. The default |
2283 | for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles | |
2284 | the ike/esp parameter the same way as pluto. As this syntax does | |
b6b90b68 | 2285 | not allow specification of a pseudo random function, the same |
c15c3d4b MW |
2286 | algorithm as for integrity is used (currently sha/md5). Supported |
2287 | algorithms for IKE: | |
2288 | Encryption: aes128, aes192, aes256 | |
2289 | Integrity/PRF: md5, sha (using hmac) | |
2290 | DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192 | |
2291 | and for ESP: | |
b6b90b68 | 2292 | Encryption: aes128, aes192, aes256, 3des, blowfish128, |
c15c3d4b MW |
2293 | blowfish192, blowfish256 |
2294 | Integrity: md5, sha1 | |
2295 | More IKE encryption algorithms will come after porting libcrypto into | |
b6b90b68 | 2296 | libstrongswan. |
f2c2d395 | 2297 | |
c15c3d4b MW |
2298 | - initial support for rekeying CHILD_SAs using IKEv2. Currently no |
2299 | perfect forward secrecy is used. The rekeying parameters rekey, | |
22ff6f57 | 2300 | rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported |
c15c3d4b MW |
2301 | when using IKEv2. WARNING: charon currently is unable to handle |
2302 | simultaneous rekeying. To avoid such a situation, use a large | |
2303 | rekeyfuzz, or even better, set rekey=no on one peer. | |
22ff6f57 | 2304 | |
7e81e975 MW |
2305 | - support for host2host, net2net, host2net (roadwarrior) tunnels |
2306 | using predefined RSA certificates (see uml scenarios for | |
2307 | configuration examples). | |
2308 | ||
f2c2d395 MW |
2309 | - new build environment featuring autotools. Features such |
2310 | as HTTP, LDAP and smartcard support may be enabled using | |
b6b90b68 | 2311 | the ./configure script. Changing install directories |
f2c2d395 MW |
2312 | is possible, too. See ./configure --help for more details. |
2313 | ||
22ff6f57 MW |
2314 | - better integration of charon with ipsec starter, which allows |
2315 | (almost) transparent operation with both daemons. charon | |
2316 | handles ipsec commands up, down, status, statusall, listall, | |
2317 | listcerts and allows proper load, reload and delete of connections | |
2318 | via ipsec starter. | |
2319 | ||
b425d998 | 2320 | |
9820c0e2 MW |
2321 | strongswan-4.0.0 |
2322 | ---------------- | |
2323 | ||
2324 | - initial support of the IKEv2 protocol. Connections in | |
b6b90b68 | 2325 | ipsec.conf designated by keyexchange=ikev2 are negotiated |
9820c0e2 MW |
2326 | by the new IKEv2 charon keying daemon whereas those marked |
2327 | by keyexchange=ikev1 or the default keyexchange=ike are | |
2328 | handled thy the IKEv1 pluto keying daemon. Currently only | |
2329 | a limited subset of functions are available with IKEv2 | |
2330 | (Default AES encryption, authentication based on locally | |
2331 | imported X.509 certificates, unencrypted private RSA keys | |
2332 | in PKCS#1 file format, limited functionality of the ipsec | |
2333 | status command). | |
2334 | ||
2335 | ||
997358a6 MW |
2336 | strongswan-2.7.0 |
2337 | ---------------- | |
2338 | ||
2339 | - the dynamic iptables rules from the _updown_x509 template | |
2340 | for KLIPS and the _updown_policy template for NETKEY have | |
2341 | been merged into the default _updown script. The existing | |
2342 | left|rightfirewall keyword causes the automatic insertion | |
2343 | and deletion of ACCEPT rules for tunneled traffic upon | |
2344 | the successful setup and teardown of an IPsec SA, respectively. | |
2345 | left|rightfirwall can be used with KLIPS under any Linux 2.4 | |
2346 | kernel or with NETKEY under a Linux kernel version >= 2.6.16 | |
f3bb1bd0 | 2347 | in conjunction with iptables >= 1.3.5. For NETKEY under a Linux |
997358a6 MW |
2348 | kernel version < 2.6.16 which does not support IPsec policy |
2349 | matching yet, please continue to use a copy of the _updown_espmark | |
2350 | template loaded via the left|rightupdown keyword. | |
2351 | ||
2352 | - a new left|righthostaccess keyword has been introduced which | |
2353 | can be used in conjunction with left|rightfirewall and the | |
2354 | default _updown script. By default leftfirewall=yes inserts | |
2355 | a bi-directional iptables FORWARD rule for a local client network | |
2356 | with a netmask different from 255.255.255.255 (single host). | |
2357 | This does not allow to access the VPN gateway host via its | |
2358 | internal network interface which is part of the client subnet | |
2359 | because an iptables INPUT and OUTPUT rule would be required. | |
2360 | lefthostaccess=yes will cause this additional ACCEPT rules to | |
b6b90b68 | 2361 | be inserted. |
997358a6 MW |
2362 | |
2363 | - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal | |
2364 | payload is preparsed in order to find out whether the roadwarrior | |
2365 | requests PSK or RSA so that a matching connection candidate can | |
2366 | be found. | |
2367 | ||
2368 | ||
2369 | strongswan-2.6.4 | |
2370 | ---------------- | |
2371 | ||
2372 | - the new _updown_policy template allows ipsec policy based | |
2373 | iptables firewall rules. Required are iptables version | |
2374 | >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes | |
b6b90b68 | 2375 | the _updown_espmark template, so that no INPUT mangle rules |
997358a6 MW |
2376 | are required any more. |
2377 | ||
2378 | - added support of DPD restart mode | |
2379 | ||
2380 | - ipsec starter now allows the use of wildcards in include | |
2381 | statements as e.g. in "include /etc/my_ipsec/*.conf". | |
2382 | Patch courtesy of Matthias Haas. | |
2383 | ||
2384 | - the Netscape OID 'employeeNumber' is now recognized and can be | |
2385 | used as a Relative Distinguished Name in certificates. | |
2386 | ||
2387 | ||
2388 | strongswan-2.6.3 | |
2389 | ---------------- | |
2390 | ||
b6b90b68 | 2391 | - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec |
997358a6 MW |
2392 | command and not of ipsec setup any more. |
2393 | ||
2394 | - ipsec starter now supports AH authentication in conjunction with | |
2395 | ESP encryption. AH authentication is configured in ipsec.conf | |
2396 | via the auth=ah parameter. | |
b6b90b68 | 2397 | |
997358a6 MW |
2398 | - The command ipsec scencrypt|scdecrypt <args> is now an alias for |
2399 | ipsec whack --scencrypt|scdecrypt <args>. | |
2400 | ||
2401 | - get_sa_info() now determines for the native netkey IPsec stack | |
2402 | the exact time of the last use of an active eroute. This information | |
2403 | is used by the Dead Peer Detection algorithm and is also displayed by | |
2404 | the ipsec status command. | |
b6b90b68 | 2405 | |
997358a6 MW |
2406 | |
2407 | strongswan-2.6.2 | |
2408 | ---------------- | |
2409 | ||
2410 | - running under the native Linux 2.6 IPsec stack, the function | |
2411 | get_sa_info() is called by ipsec auto --status to display the current | |
2412 | number of transmitted bytes per IPsec SA. | |
2413 | ||
2414 | - get_sa_info() is also used by the Dead Peer Detection process to detect | |
2415 | recent ESP activity. If ESP traffic was received from the peer within | |
2416 | the last dpd_delay interval then no R_Y_THERE notification must be sent. | |
2417 | ||
2418 | - strongSwan now supports the Relative Distinguished Name "unstructuredName" | |
2419 | in ID_DER_ASN1_DN identities. The following notations are possible: | |
2420 | ||
2421 | rightid="unstructuredName=John Doe" | |
2422 | rightid="UN=John Doe" | |
2423 | ||
2424 | - fixed a long-standing bug which caused PSK-based roadwarrior connections | |
2425 | to segfault in the function id.c:same_id() called by keys.c:get_secret() | |
2426 | if an FQDN, USER_FQDN, or Key ID was defined, as in the following example. | |
2427 | ||
2428 | conn rw | |
2429 | right=%any | |
2430 | rightid=@foo.bar | |
2431 | authby=secret | |
2432 | ||
2433 | - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall). | |
2434 | ||
2435 | - ipsec starter didn't set host_addr and client.addr ports in whack msg. | |
2436 | ||
2437 | - in order to guarantee backwards-compatibility with the script-based | |
2438 | auto function (e.g. auto --replace), the ipsec starter scripts stores | |
2439 | the defaultroute information in the temporary file /var/run/ipsec.info. | |
2440 | ||
2441 | - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH | |
2442 | Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config | |
2443 | servers. | |
2444 | ||
2445 | - the ipsec starter now also recognizes the parameters authby=never and | |
2446 | type=passthrough|pass|drop|reject. | |
2447 | ||
2448 | ||
2449 | strongswan-2.6.1 | |
2450 | ---------------- | |
2451 | ||
2452 | - ipsec starter now supports the also parameter which allows | |
2453 | a modular structure of the connection definitions. Thus | |
2454 | "ipsec start" is now ready to replace "ipsec setup". | |
2455 | ||
2456 | ||
2457 | strongswan-2.6.0 | |
2458 | ---------------- | |
2459 | ||
2460 | - Mathieu Lafon's popular ipsec starter tool has been added to the | |
2461 | strongSwan distribution. Many thanks go to Stephan Scholz from astaro | |
2462 | for his integration work. ipsec starter is a C program which is going | |
2463 | to replace the various shell and awk starter scripts (setup, _plutoload, | |
2464 | _plutostart, _realsetup, _startklips, _confread, and auto). Since | |
2465 | ipsec.conf is now parsed only once, the starting of multiple tunnels is | |
2466 | accelerated tremedously. | |
2467 | ||
2468 | - Added support of %defaultroute to the ipsec starter. If the IP address | |
b6b90b68 | 2469 | changes, a HUP signal to the ipsec starter will automatically |
997358a6 MW |
2470 | reload pluto's connections. |
2471 | ||
2472 | - moved most compile time configurations from pluto/Makefile to | |
2473 | Makefile.inc by defining the options USE_LIBCURL, USE_LDAP, | |
2474 | USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE. | |
2475 | ||
2476 | - removed the ipsec verify and ipsec newhostkey commands | |
2477 | ||
2478 | - fixed some 64-bit issues in formatted print statements | |
2479 | ||
2480 | - The scepclient functionality implementing the Simple Certificate | |
2481 | Enrollment Protocol (SCEP) is nearly complete but hasn't been | |
2482 | documented yet. | |
2483 | ||
2484 | ||
2485 | strongswan-2.5.7 | |
2486 | ---------------- | |
2487 | ||
2488 | - CA certicates are now automatically loaded from a smartcard | |
2489 | or USB crypto token and appear in the ipsec auto --listcacerts | |
2490 | listing. | |
2491 | ||
2492 | ||
2493 | strongswan-2.5.6 | |
2494 | ---------------- | |
2495 | ||
2496 | - when using "ipsec whack --scencrypt <data>" with a PKCS#11 | |
2497 | library that does not support the C_Encrypt() Cryptoki | |
2498 | function (e.g. OpenSC), the RSA encryption is done in | |
2499 | software using the public key fetched from the smartcard. | |
2500 | ||
b6b90b68 | 2501 | - The scepclient function now allows to define the |
997358a6 MW |
2502 | validity of a self-signed certificate using the --days, |
2503 | --startdate, and --enddate options. The default validity | |
2504 | has been changed from one year to five years. | |
2505 | ||
2506 | ||
2507 | strongswan-2.5.5 | |
2508 | ---------------- | |
2509 | ||
2510 | - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11 | |
2511 | interface to other applications for RSA encryption and decryption | |
2512 | via the whack interface. Notation: | |
2513 | ||
2514 | ipsec whack --scencrypt <data> | |
2515 | [--inbase 16|hex|64|base64|256|text|ascii] | |
2516 | [--outbase 16|hex|64|base64|256|text|ascii] | |
2517 | [--keyid <keyid>] | |
2518 | ||
2519 | ipsec whack --scdecrypt <data> | |
2520 | [--inbase 16|hex|64|base64|256|text|ascii] | |
2521 | [--outbase 16|hex|64|base64|256|text|ascii] | |
2522 | [--keyid <keyid>] | |
2523 | ||
b6b90b68 | 2524 | The default setting for inbase and outbase is hex. |
997358a6 MW |
2525 | |
2526 | The new proxy interface can be used for securing symmetric | |
2527 | encryption keys required by the cryptoloop or dm-crypt | |
2528 | disk encryption schemes, especially in the case when | |
2529 | pkcs11keepstate=yes causes pluto to lock the pkcs11 slot | |
2530 | permanently. | |
2531 | ||
2532 | - if the file /etc/ipsec.secrets is lacking during the startup of | |
2533 | pluto then the root-readable file /etc/ipsec.d/private/myKey.der | |
2534 | containing a 2048 bit RSA private key and a matching self-signed | |
2535 | certificate stored in the file /etc/ipsec.d/certs/selfCert.der | |
2536 | is automatically generated by calling the function | |
2537 | ||
2538 | ipsec scepclient --out pkcs1 --out cert-self | |
2539 | ||
2540 | scepclient was written by Jan Hutter and Martin Willi, students | |
2541 | at the University of Applied Sciences in Rapperswil, Switzerland. | |
2542 | ||
2543 | ||
2544 | strongswan-2.5.4 | |
2545 | ---------------- | |
2546 | ||
2547 | - the current extension of the PKCS#7 framework introduced | |
2548 | a parsing error in PKCS#7 wrapped X.509 certificates that are | |
2549 | e.g. transmitted by Windows XP when multi-level CAs are used. | |
2550 | the parsing syntax has been fixed. | |
2551 | ||
2552 | - added a patch by Gerald Richter which tolerates multiple occurrences | |
2553 | of the ipsec0 interface when using KLIPS. | |
2554 | ||
2555 | ||
2556 | strongswan-2.5.3 | |
2557 | ---------------- | |
2558 | ||
2559 | - with gawk-3.1.4 the word "default2 has become a protected | |
2560 | keyword for use in switch statements and cannot be used any | |
2561 | more in the strongSwan scripts. This problem has been | |
2562 | solved by renaming "default" to "defaults" and "setdefault" | |
2563 | in the scripts _confread and auto, respectively. | |
2564 | ||
2565 | - introduced the parameter leftsendcert with the values | |
2566 | ||
2567 | always|yes (the default, always send a cert) | |
2568 | ifasked (send the cert only upon a cert request) | |
2569 | never|no (never send a cert, used for raw RSA keys and | |
b6b90b68 | 2570 | self-signed certs) |
997358a6 MW |
2571 | |
2572 | - fixed the initialization of the ESP key length to a default of | |
2573 | 128 bits in the case that the peer does not send a key length | |
2574 | attribute for AES encryption. | |
2575 | ||
2576 | - applied Herbert Xu's uniqueIDs patch | |
2577 | ||
2578 | - applied Herbert Xu's CLOEXEC patches | |
2579 | ||
2580 | ||
2581 | strongswan-2.5.2 | |
2582 | ---------------- | |
2583 | ||
2584 | - CRLs can now be cached also in the case when the issuer's | |
2585 | certificate does not contain a subjectKeyIdentifier field. | |
2586 | In that case the subjectKeyIdentifier is computed by pluto as the | |
2587 | 160 bit SHA-1 hash of the issuer's public key in compliance | |
2588 | with section 4.2.1.2 of RFC 3280. | |
2589 | ||
2590 | - Fixed a bug introduced by strongswan-2.5.1 which eliminated | |
2591 | not only multiple Quick Modes of a given connection but also | |
2592 | multiple connections between two security gateways. | |
2593 | ||
2594 | ||
2595 | strongswan-2.5.1 | |
2596 | ---------------- | |
2597 | ||
2598 | - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute | |
2599 | installed either by setting auto=route in ipsec.conf or by | |
2600 | a connection put into hold, generates an XFRM_AQUIRE event | |
2601 | for each packet that wants to use the not-yet exisiting | |
2602 | tunnel. Up to now each XFRM_AQUIRE event led to an entry in | |
2603 | the Quick Mode queue, causing multiple IPsec SA to be | |
2604 | established in rapid succession. Starting with strongswan-2.5.1 | |
2605 | only a single IPsec SA is established per host-pair connection. | |
2606 | ||
2607 | - Right after loading the PKCS#11 module, all smartcard slots are | |
2608 | searched for certificates. The result can be viewed using | |
2609 | the command | |
2610 | ||
2611 | ipsec auto --listcards | |
2612 | ||
2613 | The certificate objects found in the slots are numbered | |
2614 | starting with #1, #2, etc. This position number can be used to address | |
2615 | certificates (leftcert=%smartcard) and keys (: PIN %smartcard) | |
2616 | in ipsec.conf and ipsec.secrets, respectively: | |
2617 | ||
2618 | %smartcard (selects object #1) | |
2619 | %smartcard#1 (selects object #1) | |
2620 | %smartcard#3 (selects object #3) | |
2621 | ||
2622 | As an alternative the existing retrieval scheme can be used: | |
2623 | ||
2624 | %smartcard:45 (selects object with id=45) | |
2625 | %smartcard0 (selects first object in slot 0) | |
2626 | %smartcard4:45 (selects object in slot 4 with id=45) | |
2627 | ||
2628 | - Depending on the settings of CKA_SIGN and CKA_DECRYPT | |
2629 | private key flags either C_Sign() or C_Decrypt() is used | |
2630 | to generate a signature. | |
2631 | ||
2632 | - The output buffer length parameter siglen in C_Sign() | |
2633 | is now initialized to the actual size of the output | |
2634 | buffer prior to the function call. This fixes the | |
2635 | CKR_BUFFER_TOO_SMALL error that could occur when using | |
2636 | the OpenSC PKCS#11 module. | |
2637 | ||
2638 | - Changed the initialization of the PKCS#11 CK_MECHANISM in | |
2639 | C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }. | |
2640 | ||
2641 | - Refactored the RSA public/private key code and transferred it | |
2642 | from keys.c to the new pkcs1.c file as a preparatory step | |
2643 | towards the release of the SCEP client. | |
2644 | ||
2645 | ||
2646 | strongswan-2.5.0 | |
2647 | ---------------- | |
2648 | ||
2649 | - The loading of a PKCS#11 smartcard library module during | |
2650 | runtime does not require OpenSC library functions any more | |
2651 | because the corresponding code has been integrated into | |
2652 | smartcard.c. Also the RSAREF pkcs11 header files have been | |
2653 | included in a newly created pluto/rsaref directory so that | |
2654 | no external include path has to be defined any longer. | |
2655 | ||
2656 | - A long-awaited feature has been implemented at last: | |
2657 | The local caching of CRLs fetched via HTTP or LDAP, activated | |
2658 | by the parameter cachecrls=yes in the config setup section | |
2659 | of ipsec.conf. The dynamically fetched CRLs are stored under | |
2660 | a unique file name containing the issuer's subjectKeyID | |
2661 | in /etc/ipsec.d/crls. | |
b6b90b68 | 2662 | |
997358a6 MW |
2663 | - Applied a one-line patch courtesy of Michael Richardson |
2664 | from the Openswan project which fixes the kernel-oops | |
2665 | in KLIPS when an snmp daemon is running on the same box. | |
2666 | ||
2667 | ||
2668 | strongswan-2.4.4 | |
2669 | ---------------- | |
2670 | ||
2671 | - Eliminated null length CRL distribution point strings. | |
2672 | ||
2673 | - Fixed a trust path evaluation bug introduced with 2.4.3 | |
2674 | ||
2675 | ||
2676 | strongswan-2.4.3 | |
2677 | ---------------- | |
2678 | ||
2679 | - Improved the joint OCSP / CRL revocation policy. | |
2680 | OCSP responses have precedence over CRL entries. | |
2681 | ||
2682 | - Introduced support of CRLv2 reason codes. | |
2683 | ||
2684 | - Fixed a bug with key-pad equipped readers which caused | |
2685 | pluto to prompt for the pin via the console when the first | |
2686 | occasion to enter the pin via the key-pad was missed. | |
2687 | ||
2688 | - When pluto is built with LDAP_V3 enabled, the library | |
2689 | liblber required by newer versions of openldap is now | |
2690 | included. | |
2691 | ||
2692 | ||
2693 | strongswan-2.4.2 | |
2694 | ---------------- | |
2695 | ||
2696 | - Added the _updown_espmark template which requires all | |
2697 | incoming ESP traffic to be marked with a default mark | |
2698 | value of 50. | |
b6b90b68 | 2699 | |
997358a6 MW |
2700 | - Introduced the pkcs11keepstate parameter in the config setup |
2701 | section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11 | |
b6b90b68 | 2702 | session and login states are kept as long as possible during |
997358a6 MW |
2703 | the lifetime of pluto. This means that a PIN entry via a key |
2704 | pad has to be done only once. | |
2705 | ||
2706 | - Introduced the pkcs11module parameter in the config setup | |
2707 | section of ipsec.conf which specifies the PKCS#11 module | |
2708 | to be used with smart cards. Example: | |
b6b90b68 | 2709 | |
997358a6 | 2710 | pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo |
b6b90b68 | 2711 | |
997358a6 MW |
2712 | - Added support of smartcard readers equipped with a PIN pad. |
2713 | ||
2714 | - Added patch by Jay Pfeifer which detects when netkey | |
2715 | modules have been statically built into the Linux 2.6 kernel. | |
2716 | ||
2717 | - Added two patches by Herbert Xu. The first uses ip xfrm | |
2718 | instead of setkey to flush the IPsec policy database. The | |
2719 | second sets the optional flag in inbound IPComp SAs only. | |
b6b90b68 | 2720 | |
997358a6 MW |
2721 | - Applied Ulrich Weber's patch which fixes an interoperability |
2722 | problem between native IPsec and KLIPS systems caused by | |
2723 | setting the replay window to 32 instead of 0 for ipcomp. | |
2724 | ||
2725 | ||
2726 | strongswan-2.4.1 | |
2727 | ---------------- | |
2728 | ||
2729 | - Fixed a bug which caused an unwanted Mode Config request | |
2730 | to be initiated in the case where "right" was used to denote | |
2731 | the local side in ipsec.conf and "left" the remote side, | |
2732 | contrary to the recommendation that "right" be remote and | |
2733 | "left" be"local". | |
2734 | ||
2735 | ||
2736 | strongswan-2.4.0a | |
2737 | ----------------- | |
2738 | ||
2739 | - updated Vendor ID to strongSwan-2.4.0 | |
2740 | ||
2741 | - updated copyright statement to include David Buechi and | |
2742 | Michael Meier | |
b6b90b68 MW |
2743 | |
2744 | ||
997358a6 MW |
2745 | strongswan-2.4.0 |
2746 | ---------------- | |
2747 | ||
2748 | - strongSwan now communicates with attached smartcards and | |
2749 | USB crypto tokens via the standardized PKCS #11 interface. | |
2750 | By default the OpenSC library from www.opensc.org is used | |
2751 | but any other PKCS#11 library could be dynamically linked. | |
2752 | strongSwan's PKCS#11 API was implemented by David Buechi | |
2753 | and Michael Meier, both graduates of the Zurich University | |
2754 | of Applied Sciences in Winterthur, Switzerland. | |
2755 | ||
2756 | - When a %trap eroute is triggered by an outgoing IP packet | |
2757 | then the native IPsec stack of the Linux 2.6 kernel [often/ | |
2758 | always?] returns an XFRM_ACQUIRE message with an undefined | |
2759 | protocol family field and the connection setup fails. | |
2760 | As a workaround IPv4 (AF_INET) is now assumed. | |
b6b90b68 MW |
2761 | |
2762 | - the results of the UML test scenarios are now enhanced | |
997358a6 | 2763 | with block diagrams of the virtual network topology used |
b6b90b68 | 2764 | in a particular test. |
997358a6 MW |
2765 | |
2766 | ||
2767 | strongswan-2.3.2 | |
2768 | ---------------- | |
2769 | ||
2770 | - fixed IV used to decrypt informational messages. | |
2771 | This bug was introduced with Mode Config functionality. | |
b6b90b68 | 2772 | |
997358a6 MW |
2773 | - fixed NCP Vendor ID. |
2774 | ||
2775 | - undid one of Ulrich Weber's maximum udp size patches | |
2776 | because it caused a segmentation fault with NAT-ed | |
2777 | Delete SA messages. | |
b6b90b68 | 2778 | |
997358a6 MW |
2779 | - added UML scenarios wildcards and attr-cert which |
2780 | demonstrate the implementation of IPsec policies based | |
2781 | on wildcard parameters contained in Distinguished Names and | |
2782 | on X.509 attribute certificates, respectively. | |
2783 | ||
2784 | ||
2785 | strongswan-2.3.1 | |
2786 | ---------------- | |
2787 | ||
2788 | - Added basic Mode Config functionality | |
2789 | ||
2790 | - Added Mathieu Lafon's patch which upgrades the status of | |
2791 | the NAT-Traversal implementation to RFC 3947. | |
b6b90b68 | 2792 | |
997358a6 MW |
2793 | - The _startklips script now also loads the xfrm4_tunnel |
2794 | module. | |
b6b90b68 | 2795 | |
997358a6 MW |
2796 | - Added Ulrich Weber's netlink replay window size and |
2797 | maximum udp size patches. | |
2798 | ||
2799 | - UML testing now uses the Linux 2.6.10 UML kernel by default. | |
b6b90b68 | 2800 | |
997358a6 MW |
2801 | |
2802 | strongswan-2.3.0 | |
2803 | ---------------- | |
2804 | ||
2805 | - Eric Marchionni and Patrik Rayo, both recent graduates from | |
2806 | the Zuercher Hochschule Winterthur in Switzerland, created a | |
2807 | User-Mode-Linux test setup for strongSwan. For more details | |
2808 | please read the INSTALL and README documents in the testing | |
2809 | subdirectory. | |
2810 | ||
2811 | - Full support of group attributes based on X.509 attribute | |
b6b90b68 | 2812 | certificates. Attribute certificates can be generated |
997358a6 | 2813 | using the openac facility. For more details see |
b6b90b68 | 2814 | |
997358a6 | 2815 | man ipsec_openac. |
b6b90b68 | 2816 | |
997358a6 MW |
2817 | The group attributes can be used in connection definitions |
2818 | in order to give IPsec access to specific user groups. | |
2819 | This is done with the new parameter left|rightgroups as in | |
b6b90b68 | 2820 | |
997358a6 MW |
2821 | rightgroups="Research, Sales" |
2822 | ||
2823 | giving access to users possessing the group attributes | |
2824 | Research or Sales, only. | |
2825 | ||
2826 | - In Quick Mode clients with subnet mask /32 are now | |
b6b90b68 | 2827 | coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should |
997358a6 MW |
2828 | fix rekeying problems with the SafeNet/SoftRemote and NCP |
2829 | Secure Entry Clients. | |
2830 | ||
2831 | - Changed the defaults of the ikelifetime and keylife parameters | |
2832 | to 3h and 1h, respectively. The maximum allowable values are | |
2833 | now both set to 24 h. | |
2834 | ||
2835 | - Suppressed notification wars between two IPsec peers that | |
2836 | could e.g. be triggered by incorrect ISAKMP encryption. | |
2837 | ||
2838 | - Public RSA keys can now have identical IDs if either the | |
2839 | issuing CA or the serial number is different. The serial | |
2840 | number of a certificate is now shown by the command | |
b6b90b68 | 2841 | |
997358a6 MW |
2842 | ipsec auto --listpubkeys |
2843 | ||
2844 | ||
2845 | strongswan-2.2.2 | |
2846 | ---------------- | |
2847 | ||
2848 | - Added Tuomo Soini's sourceip feature which allows a strongSwan | |
2849 | roadwarrior to use a fixed Virtual IP (see README section 2.6) | |
2850 | and reduces the well-known four tunnel case on VPN gateways to | |
2851 | a single tunnel definition (see README section 2.4). | |
2852 | ||
f3bb1bd0 | 2853 | - Fixed a bug occurring with NAT-Traversal enabled when the responder |
997358a6 MW |
2854 | suddenly turns initiator and the initiator cannot find a matching |
2855 | connection because of the floated IKE port 4500. | |
b6b90b68 | 2856 | |
997358a6 MW |
2857 | - Removed misleading ipsec verify command from barf. |
2858 | ||
2859 | - Running under the native IP stack, ipsec --version now shows | |
2860 | the Linux kernel version (courtesy to the Openswan project). | |
2861 | ||
2862 | ||
2863 | strongswan-2.2.1 | |
2864 | ---------------- | |
2865 | ||
2866 | - Introduced the ipsec auto --listalgs monitoring command which lists | |
2867 | all currently registered IKE and ESP algorithms. | |
2868 | ||
f3bb1bd0 | 2869 | - Fixed a bug in the ESP algorithm selection occurring when the strict flag |
997358a6 | 2870 | is set and the first proposed transform does not match. |
b6b90b68 | 2871 | |
997358a6 | 2872 | - Fixed another deadlock in the use of the lock_certs_and_keys() mutex, |
f3bb1bd0 | 2873 | occurring when a smartcard is present. |
997358a6 MW |
2874 | |
2875 | - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event. | |
b6b90b68 | 2876 | |
997358a6 MW |
2877 | - Fixed the printing of the notification names (null) |
2878 | ||
2879 | - Applied another of Herbert Xu's Netlink patches. | |
2880 | ||
2881 | ||
2882 | strongswan-2.2.0 | |
2883 | ---------------- | |
2884 | ||
2885 | - Support of Dead Peer Detection. The connection parameter | |
2886 | ||
2887 | dpdaction=clear|hold | |
b6b90b68 | 2888 | |
997358a6 MW |
2889 | activates DPD for the given connection. |
2890 | ||
2891 | - The default Opportunistic Encryption (OE) policy groups are not | |
2892 | automatically included anymore. Those wishing to activate OE can include | |
2893 | the policy group with the following statement in ipsec.conf: | |
b6b90b68 | 2894 | |
997358a6 | 2895 | include /etc/ipsec.d/examples/oe.conf |
b6b90b68 | 2896 | |
997358a6 MW |
2897 | The default for [right|left]rsasigkey is now set to %cert. |
2898 | ||
2899 | - strongSwan now has a Vendor ID of its own which can be activated | |
2900 | using the compile option VENDORID | |
2901 | ||
2902 | - Applied Herbert Xu's patch which sets the compression algorithm correctly. | |
2903 | ||
2904 | - Applied Herbert Xu's patch fixing an ESPINUDP problem | |
2905 | ||
2906 | - Applied Herbert Xu's patch setting source/destination port numbers. | |
2907 | ||
2908 | - Reapplied one of Herbert Xu's NAT-Traversal patches which got | |
2909 | lost during the migration from SuperFreeS/WAN. | |
b6b90b68 | 2910 | |
997358a6 MW |
2911 | - Fixed a deadlock in the use of the lock_certs_and_keys() mutex. |
2912 | ||
2913 | - Fixed the unsharing of alg parameters when instantiating group | |
2914 | connection. | |
b6b90b68 | 2915 | |
997358a6 MW |
2916 | |
2917 | strongswan-2.1.5 | |
2918 | ---------------- | |
2919 | ||
2920 | - Thomas Walpuski made me aware of a potential DoS attack via | |
2921 | a PKCS#7-wrapped certificate bundle which could overwrite valid CA | |
2922 | certificates in Pluto's authority certificate store. This vulnerability | |
2923 | was fixed by establishing trust in CA candidate certificates up to a | |
2924 | trusted root CA prior to insertion into Pluto's chained list. | |
2925 | ||
2926 | - replaced the --assign option by the -v option in the auto awk script | |
2927 | in order to make it run with mawk under debian/woody. | |
2928 | ||
2929 | ||
2930 | strongswan-2.1.4 | |
2931 | ---------------- | |
2932 | ||
2933 | - Split of the status information between ipsec auto --status (concise) | |
2934 | and ipsec auto --statusall (verbose). Both commands can be used with | |
2935 | an optional connection selector: | |
2936 | ||
2937 | ipsec auto --status[all] <connection_name> | |
2938 | ||
2939 | - Added the description of X.509 related features to the ipsec_auto(8) | |
2940 | man page. | |
2941 | ||
2942 | - Hardened the ASN.1 parser in debug mode, especially the printing | |
2943 | of malformed distinguished names. | |
2944 | ||
2945 | - The size of an RSA public key received in a certificate is now restricted to | |
2946 | ||
2947 | 512 bits <= modulus length <= 8192 bits. | |
2948 | ||
2949 | - Fixed the debug mode enumeration. | |
2950 | ||
2951 | ||
2952 | strongswan-2.1.3 | |
2953 | ---------------- | |
2954 | ||
2955 | - Fixed another PKCS#7 vulnerability which could lead to an | |
2956 | endless loop while following the X.509 trust chain. | |
b6b90b68 | 2957 | |
997358a6 MW |
2958 | |
2959 | strongswan-2.1.2 | |
2960 | ---------------- | |
2961 | ||
2962 | - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski | |
2963 | that accepted end certificates having identical issuer and subject | |
2964 | distinguished names in a multi-tier X.509 trust chain. | |
b6b90b68 | 2965 | |
997358a6 MW |
2966 | |
2967 | strongswan-2.1.1 | |
2968 | ---------------- | |
2969 | ||
2970 | - Removed all remaining references to ipsec_netlink.h in KLIPS. | |
2971 | ||
2972 | ||
2973 | strongswan-2.1.0 | |
2974 | ---------------- | |
2975 | ||
2976 | - The new "ca" section allows to define the following parameters: | |
2977 | ||
2978 | ca kool | |
2979 | cacert=koolCA.pem # cacert of kool CA | |
2980 | ocspuri=http://ocsp.kool.net:8001 # ocsp server | |
2981 | ldapserver=ldap.kool.net # default ldap server | |
2982 | crluri=http://www.kool.net/kool.crl # crl distribution point | |
2983 | crluri2="ldap:///O=Kool, C= .." # crl distribution point #2 | |
2984 | auto=add # add, ignore | |
b6b90b68 | 2985 | |
997358a6 | 2986 | The ca definitions can be monitored via the command |
b6b90b68 | 2987 | |
997358a6 MW |
2988 | ipsec auto --listcainfos |
2989 | ||
2990 | - Fixed cosmetic corruption of /proc filesystem by integrating | |
2991 | D. Hugh Redelmeier's freeswan-2.06 kernel fixes. | |
2992 | ||
2993 | ||
2994 | strongswan-2.0.2 | |
2995 | ---------------- | |
2996 | ||
2997 | - Added support for the 818043 NAT-Traversal update of Microsoft's | |
2998 | Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode. | |
b6b90b68 MW |
2999 | |
3000 | - A symbolic link to libcrypto is now added in the kernel sources | |
997358a6 | 3001 | during kernel compilation |
b6b90b68 | 3002 | |
997358a6 MW |
3003 | - Fixed a couple of 64 bit issues (mostly casts to int). |
3004 | Thanks to Ken Bantoft who checked my sources on a 64 bit platform. | |
3005 | ||
3006 | - Replaced s[n]printf() statements in the kernel by ipsec_snprintf(). | |
3007 | Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro | |
3008 | of the FreeS/WAN team who solved this problem with the 2.4.25 kernel. | |
3009 | ||
3010 | ||
3011 | strongswan-2.0.1 | |
3012 | ---------------- | |
3013 | ||
3014 | - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName | |
3015 | certificate extension which contains no generalName item) can cause | |
3016 | a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has | |
3017 | been hardened to make it more robust against malformed ASN.1 objects. | |
3018 | ||
3019 | - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native | |
3020 | Linux 2.6 IPsec stack. | |
b6b90b68 MW |
3021 | |
3022 | ||
997358a6 MW |
3023 | strongswan-2.0.0 |
3024 | ---------------- | |
3025 | ||
3026 | - based on freeswan-2.04, x509-1.5.3, nat-0.6c, alg-0.8.1rc12 |
