2 | ---------------- | |
3 | ||
011195f1 AS |
4 | - Support of Diffie-Hellman group 31 using Curve25519 for IKE as defined |
5 | by RFC 8031. | |
6 | ||
65797c9f AS |
7 | - Support of Ed25519 digital signature algorithm for IKEv2 as defined by |
8 | draft-ietf-ipsecme-eddsa. Ed25519-based public key pairs, X.509 certificates | |
9 | and CRLs can be generated and printed by the pki tool. | |
10 | ||
4a979994 AS |
11 | - In-place update of cached base and delta CRLs does no leave dozens |
12 | of stale copies in cache memory. | |
13 | ||

8aaa6de3 AS |
15 | strongswan-5.5.1 |
16 | ---------------- | |
17 | ||
18 | - The newhope plugin implements the post-quantum NewHope key exchange algorithm | |
19 | proposed in their 2015 paper by Erdem Alkim, Léo Ducas, Thomas Pöppelmann and | |
20 | Peter Schwabe. | |
21 | ||
e31ed9ab AS |
22 | - The libstrongswan crypto factory now offers the registration of Extended |
23 | Output Functions (XOFs). Currently supported XOFs are SHAKE128 and SHAKE256 | |
24 | implemented by the sha3 plugin, ChaCHa20 implemented by the chapoly plugin | |
25 | and the more traditional MGF1 Mask Generation Functions based on the SHA-1, | |
26 | SHA-256 and SHA-512 hash algorithms implemented by the new mgf1 plugin. | |
27 | ||
e6a4bd83 AS |
28 | - The pki tool, with help of the pkcs1 or openssl plugins, can parse private |
29 | keys in any of the supported formats without having to know the exact type. | |
30 | So instead of having to specify rsa or ecdsa explicitly the keyword priv may | |
31 | be used to indicate a private key of any type. Similarly, swanctl can load | |
32 | any type of private key from the swanctl/private directory. | |
33 | ||
6b3e408b AS |
34 | - The pki tool can handle RSASSA-PKCS1v1.5-with-SHA-3 signatures using the |
35 | sha3 and gmp plugins. | |
36 | ||
e31ed9ab | 37 | - The VICI flush-certs command flushes certificates from the volatile |
8aaa6de3 AS |
38 | certificate cache. Optionally the type of the certificates to be |
39 | flushed (e.g. type = x509_crl) can be specified. | |
40 | ||
a617223e AS |
41 | - Setting cache_crls = yes in strongswan.conf the vici plugin saves regular, |
42 | base and delta CRLs to disk. | |
43 | ||
e6a4bd83 AS |
44 | - IKE fragmentation is now enabled by default with the default fragment size |
45 | set to 1280 bytes for both IP address families. | |
46 | ||
8aaa6de3 AS |
47 | - libtpmtss: In the TSS2 API the function TeardownSocketTcti() was replaced by |
48 | tss2_tcti_finalize(). | |
49 | ||
50 | ||
6a24637d AS |
51 | strongswan-5.5.0 |
52 | ---------------- | |
53 | ||
54 | - The new libtpmtss library offers support for both TPM 1.2 and TPM 2.0 | |
55 | Trusted Platform Modules. This allows the Attestation IMC/IMV pair to | |
56 | do TPM 2.0 based attestation. | |
57 | ||
b977ef8e TB |
58 | - The behavior during IKEv2 exchange collisions has been improved/fixed in |
59 | several corner cases and support for TEMPORARY_FAILURE and CHILD_SA_NOT_FOUND | |
60 | notifies, as defined by RFC 7296, has been added. | |
8fafbffd | 61 | |
b977ef8e TB |
62 | - IPsec policy priorities can be set manually (e.g. for high-priority drop |
63 | policies) and outbound policies may be restricted to a network interface. | |
64 | ||
65 | - The scheme for the automatically calculated default priorities has been | |
66 | changed and now also considers port masks, which were added with 5.4.0. | |
67 | ||
68 | - FWD policies are now installed in both directions in regards to the traffic | |
69 | selectors. Because such "outbound" FWD policies could conflict with "inbound" | |
70 | FWD policies of other SAs they are installed with a lower priority and don't | |
71 | have a reqid set, which allows kernel plugins to distinguish between the two | |
72 | and prefer those with a reqid. | |
73 | ||
74 | - For outbound IPsec SAs no replay window is configured anymore. | |
75 | ||
76 | - Enhanced the functionality of the swanctl --list-conns command by listing | |
77 | IKE_SA and CHILD_SA reauthentication and rekeying settings, and EAP/XAuth | |
78 | identities and EAP types. | |
79 | ||
80 | - DNS servers installed by the resolve plugin are now refcounted, which should | |
81 | fix its use with make-before-break reauthentication. Any output written to | |
82 | stderr/stdout by resolvconf is now logged. | |
83 | ||
84 | - The methods in the kernel interfaces have been changed to take structs instead | |
85 | of long lists of arguments. Similarly the constructors for peer_cfg_t and | |
86 | child_cfg_t now take structs. | |

89 | strongswan-5.4.0 |
90 | ---------------- | |
91 | ||
6fc68343 TB |
92 | - Support for IKEv2 redirection (RFC 5685) has been added. Plugins may |
93 | implement the redirect_provider_t interface to decide if and when to redirect | |
94 | connecting clients. It is also possible to redirect established IKE_SAs based | |
95 | on different selectors via VICI/swanctl. Unless disabled in strongswan.conf | |
96 | the charon daemon will follow redirect requests received from servers. | |
97 | ||
c171afea TB |
98 | - The ike: prefix enables the explicit configuration of signature scheme |
99 | constraints against IKEv2 authentication in rightauth, which allows the use | |
100 | of different signature schemes for trustchain verification and authentication. | |
101 | ||
b4337c5b TB |
102 | - The initiator of an IKEv2 make-before-break reauthentication now suspends |
103 | online certificate revocation checks (OCSP, CRLs) until the new IKE_SA and all | |
104 | CHILD_SAs are established. This is required if the checks are done over the | |
105 | CHILD_SA established with the new IKE_SA. This is not possible until the | |
106 | initiator installs this SA and that only happens after the authentication is | |
107 | completed successfully. So we suspend the checks during the reauthentication | |
108 | and do them afterwards, if they fail the IKE_SA is closed. This change has no | |
109 | effect on the behavior during the authentication of the initial IKE_SA. | |
110 | ||
b5eed58a AS |
111 | - For the vici plugin a Vici:Session Perl CPAN module has been added to allow |
112 | Perl applications to control and/or monitor the IKE daemon using the VICI | |
113 | interface, similar to the existing Python egg or Ruby gem. | |
114 | ||
5c25780c AS |
115 | - Traffic selectors with port ranges can now be configured in the Linux kernel: |
116 | e.g. remote_ts = 10.1.0.0/16[tcp/20-23] local_ts = dynamic[tcp/32768-65535]. | |
117 | The port range must map to a port mask, though since the kernel does not | |
118 | support arbitrary ranges. | |
119 | ||
bebccf98 AS |
120 | - The vici plugin allows the configuration of IPv4 and IPv6 address ranges |
121 | in local and remote traffic selectors. Since both the Linux kernel and | |
122 | iptables cannot handle arbitrary ranges, address ranges are mapped to the next | |
123 | larger CIDR subnet by the kernel-netlink and updown plugins, respectively. | |
124 | ||
125 | - Implemented IKEv1 IPv4/IPv6 address subnet and range identities that can be | |
126 | used as owners of shared secrets. | |

129 | strongswan-5.3.5 |
130 | ---------------- | |
131 | ||
132 | - Properly handle potential EINTR errors in sigwaitinfo(2) calls that replaced | |
133 | sigwait(3) calls with 5.3.4. | |
134 | ||
135 | - RADIUS retransmission timeouts are now configurable, courtesy of Thom Troy. | |

6590298d AS |
138 | strongswan-5.3.4 |
139 | ---------------- | |
140 | ||
453e204a TB |
141 | - Fixed an authentication bypass vulnerability in the eap-mschapv2 plugin that |
142 | was caused by insufficient verification of the internal state when handling | |
143 | MSCHAPv2 Success messages received by the client. | |
144 | This vulnerability has been registered as CVE-2015-8023. | |
145 | ||
6590298d AS |
146 | - The sha3 plugin implements the SHA3 Keccak-F1600 hash algorithm family. |
147 | Within the strongSwan framework SHA3 is currently used for BLISS signatures | |
148 | only because the OIDs for other signature algorithms haven't been defined | |
149 | yet. Also the use of SHA3 for IKEv2 has not been standardized yet. | |
150 | ||
151 | ||
63d37038 AS |
152 | strongswan-5.3.3 |
153 | ---------------- | |
154 | ||
18e0d66b TB |
155 | - Added support for the ChaCha20/Poly1305 AEAD cipher specified in RFC 7539 and |
156 | RFC 7634 using the chacha20poly1305 ike/esp proposal keyword. The new chapoly | |
157 | plugin implements the cipher, if possible SSE-accelerated on x86/x64 | |
158 | architectures. It is usable both in IKEv2 and the strongSwan libipsec ESP | |
159 | backend. On Linux 4.2 or newer the kernel-netlink plugin can configure the | |
160 | cipher for ESP SAs. | |
39660798 | 161 | |
63d37038 | 162 | - The vici interface now supports the configuration of auxiliary certification |
18e0d66b TB |
163 | authority information as CRL and OCSP URIs. |
164 | ||
165 | - In the bliss plugin the c_indices derivation using a SHA-512 based random | |
166 | oracle has been fixed, generalized and standardized by employing the MGF1 mask | |
167 | generation function with SHA-512. As a consequence BLISS signatures unsing the | |
168 | improved oracle are not compatible with the earlier implementation. | |
169 | ||
170 | - Support for auto=route with right=%any for transport mode connections has | |
171 | been added (the ikev2/trap-any scenario provides examples). | |
172 | ||
173 | - The starter daemon does not flush IPsec policies and SAs anymore when it is | |
174 | stopped. Already existing duplicate policies are now overwritten by the IKE | |
175 | daemon when it installs its policies. | |
176 | ||
177 | - Init limits (like charon.init_limit_half_open) can now optionally be enforced | |
178 | when initiating SAs via VICI. For this, IKE_SAs initiated by the daemon are | |
179 | now also counted as half-open SAs, which, as a side-effect, fixes the status | |
180 | output while connecting (e.g. in ipsec status). | |
181 | ||
182 | - Symmetric configuration of EAP methods in left|rightauth is now possible when | |
183 | mutual EAP-only authentication is used (previously, the client had to | |
184 | configure rightauth=eap or rightauth=any, which prevented it from using this | |
185 | same config as responder). | |
186 | ||
187 | - The initiator flag in the IKEv2 header is compared again (wasn't the case | |
188 | since 5.0.0) and packets that have the flag set incorrectly are again ignored. | |
189 | ||
a215008c | 190 | - Implemented a demo Hardcopy Device IMC/IMV pair based on the "Hardcopy |
453e204a | 191 | Device Health Assessment Trusted Network Connect Binding" (HCD-TNC) |
a215008c AS |
192 | document drafted by the IEEE Printer Working Group (PWG). |
193 | ||
194 | - Fixed IF-M segmentation which failed in the presence of multiple small | |
195 | attributes in front of a huge attribute to be segmented. | |
196 | ||
39660798 | 197 | |
2b19e517 TB |
198 | strongswan-5.3.2 |
199 | ---------------- | |
200 | ||
201 | - Fixed a vulnerability that allowed rogue servers with a valid certificate | |
202 | accepted by the client to trick it into disclosing its username and even | |
203 | password (if the client accepts EAP-GTC). This was caused because constraints | |
204 | against the responder's authentication were enforced too late. | |
205 | This vulnerability has been registered as CVE-2015-4171. | |
206 | ||
207 | ||
eb423ebb AS |
208 | strongswan-5.3.1 |
209 | ---------------- | |
210 | ||
099260d8 TB |
211 | - Fixed a denial-of-service and potential remote code execution vulnerability |
212 | triggered by IKEv1/IKEv2 messages that contain payloads for the respective | |
213 | other IKE version. Such payload are treated specially since 5.2.2 but because | |
214 | they were still identified by their original payload type they were used as | |
215 | such in some places causing invalid function pointer dereferences. | |
216 | The vulnerability has been registered as CVE-2015-3991. | |
217 | ||
e8ba1d47 MW |
218 | - The new aesni plugin provides CBC, CTR, XCBC, CMAC, CCM and GCM crypto |
219 | primitives for AES-128/192/256. The plugin requires AES-NI and PCLMULQDQ | |
220 | instructions and works on both x86 and x64 architectures. It provides | |
221 | superior crypto performance in userland without any external libraries. | |
222 | ||
223 | ||
c6595222 AS |
224 | strongswan-5.3.0 |
225 | ---------------- | |
226 | ||
4a00f912 MW |
227 | - Added support for IKEv2 make-before-break reauthentication. By using a global |
228 | CHILD_SA reqid allocation mechanism, charon supports overlapping CHILD_SAs. | |
229 | This allows the use of make-before-break instead of the previously supported | |
230 | break-before-make reauthentication, avoiding connectivity gaps during that | |
231 | procedure. As the new mechanism may fail with peers not supporting it (such | |
232 | as any previous strongSwan release) it must be explicitly enabled using | |
233 | the charon.make_before_break strongswan.conf option. | |
234 | ||
3f1ef3a6 TB |
235 | - Support for "Signature Authentication in IKEv2" (RFC 7427) has been added. |
236 | This allows the use of stronger hash algorithms for public key authentication. | |
237 | By default, signature schemes are chosen based on the strength of the | |
238 | signature key, but specific hash algorithms may be configured in leftauth. | |
239 | ||
240 | - Key types and hash algorithms specified in rightauth are now also checked | |
241 | against IKEv2 signature schemes. If such constraints are used for certificate | |
242 | chain validation in existing configurations, in particular with peers that | |
243 | don't support RFC 7427, it may be necessary to disable this feature with the | |
244 | charon.signature_authentication_constraints setting, because the signature | |
245 | scheme used in classic IKEv2 public key authentication may not be strong | |
246 | enough. | |
247 | ||
1e1e88e6 MW |
248 | - The new connmark plugin allows a host to bind conntrack flows to a specific |
249 | CHILD_SA by applying and restoring the SA mark to conntrack entries. This | |
250 | allows a peer to handle multiple transport mode connections coming over the | |
251 | same NAT device for client-initiated flows. A common use case is to protect | |
252 | L2TP/IPsec, as supported by some systems. | |
253 | ||
dc88d179 MW |
254 | - The forecast plugin can forward broadcast and multicast messages between |
255 | connected clients and a LAN. For CHILD_SA using unique marks, it sets up | |
256 | the required Netfilter rules and uses a multicast/broadcast listener that | |
257 | forwards such messages to all connected clients. This plugin is designed for | |
258 | Windows 7 IKEv2 clients, which announces its services over the tunnel if the | |
259 | negotiated IPsec policy allows it. | |
260 | ||
2185c29b MW |
261 | - For the vici plugin a Python Egg has been added to allow Python applications |
262 | to control or monitor the IKE daemon using the VICI interface, similar to the | |
263 | existing ruby gem. The Python library has been contributed by Björn Schuberg. | |
264 | ||
f05a578b MW |
265 | - EAP server methods now can fulfill public key constraints, such as rightcert |
266 | or rightca. Additionally, public key and signature constraints can be | |
267 | specified for EAP methods in the rightauth keyword. Currently the EAP-TLS and | |
268 | EAP-TTLS methods provide verification details to constraints checking. | |
269 | ||
27bd0fed AS |
270 | - Upgrade of the BLISS post-quantum signature algorithm to the improved BLISS-B |
271 | variant. Can be used in conjunction with the SHA256, SHA384 and SHA512 hash | |
272 | algorithms with SHA512 being the default. | |
273 | ||
e0359350 AS |
274 | - The IF-IMV 1.4 interface now makes the IP address of the TNC access requestor |
275 | as seen by the TNC server available to all IMVs. This information can be | |
276 | forwarded to policy enforcement points (e.g. firewalls or routers). | |
277 | ||
7b4a96b2 AS |
278 | - The new mutual tnccs-20 plugin parameter activates mutual TNC measurements |
279 | in PB-TNC half-duplex mode between two endpoints over either a PT-EAP or | |
280 | PT-TLS transport medium. | |
281 | ||

283 | strongswan-5.2.2 |
284 | ---------------- | |
285 | ||
919449a3 TB |
286 | - Fixed a denial-of-service vulnerability triggered by an IKEv2 Key Exchange |
287 | payload that contains the Diffie-Hellman group 1025. This identifier was | |
288 | used internally for DH groups with custom generator and prime. Because | |
289 | these arguments are missing when creating DH objects based on the KE payload | |
290 | an invalid pointer dereference occurred. This allowed an attacker to crash | |
291 | the IKE daemon with a single IKE_SA_INIT message containing such a KE | |
292 | payload. The vulnerability has been registered as CVE-2014-9221. | |
293 | ||
045501d5 MW |
294 | - The left/rightid options in ipsec.conf, or any other identity in strongSwan, |
295 | now accept prefixes to enforce an explicit type, such as email: or fqdn:. | |
296 | Note that no conversion is done for the remaining string, refer to | |
297 | ipsec.conf(5) for details. | |
298 | ||
30a90ccf | 299 | - The post-quantum Bimodal Lattice Signature Scheme (BLISS) can be used as |
32d19652 AS |
300 | an IKEv2 public key authentication method. The pki tool offers full support |
301 | for the generation of BLISS key pairs and certificates. | |
302 | ||
30a90ccf TB |
303 | - Fixed mapping of integrity algorithms negotiated for AH via IKEv1. This could |
304 | cause interoperability issues when connecting to older versions of charon. | |
305 | ||
045501d5 | 306 | |
dcdcae01 MW |
307 | strongswan-5.2.1 |
308 | ---------------- | |
309 | ||
310 | - The new charon-systemd IKE daemon implements an IKE daemon tailored for use | |
311 | with systemd. It avoids the dependency on ipsec starter and uses swanctl | |
312 | as configuration backend, building a simple and lightweight solution. It | |
313 | supports native systemd journal logging. | |
314 | ||
55758bec TB |
315 | - Support for IKEv2 fragmentation as per RFC 7383 has been added. Like IKEv1 |
316 | fragmentation it can be enabled by setting fragmentation=yes in ipsec.conf. | |
317 | ||
e9a93cb7 AS |
318 | - Support of the TCG TNC IF-M Attribute Segmentation specification proposal. |
319 | All attributes can be segmented. Additionally TCG/SWID Tag, TCG/SWID Tag ID | |
320 | and IETF/Installed Packages attributes can be processed incrementally on a | |
321 | per segment basis. | |
322 | ||
9180c921 MW |
323 | - The new ext-auth plugin calls an external script to implement custom IKE_SA |
324 | authorization logic, courtesy of Vyronas Tsingaras. | |
325 | ||
7431ad0d MW |
326 | - For the vici plugin a ruby gem has been added to allow ruby applications |
327 | to control or monitor the IKE daemon. The vici documentation has been updated | |
328 | to include a description of the available operations and some simple examples | |
329 | using both the libvici C interface and the ruby gem. | |

4c5e52f5 MW |
335 | - strongSwan has been ported to the Windows platform. Using a MinGW toolchain, |
336 | many parts of the strongSwan codebase run natively on Windows 7 / 2008 R2 | |
337 | and newer releases. charon-svc implements a Windows IKE service based on | |
338 | libcharon, the kernel-iph and kernel-wfp plugins act as networking and IPsec | |
339 | backend on the Windows platform. socket-win provides a native IKE socket | |
340 | implementation, while winhttp fetches CRL and OCSP information using the | |
341 | WinHTTP API. | |
342 | ||
4787523c MW |
343 | - The new vici plugin provides a Versatile IKE Configuration Interface for |
344 | charon. Using the stable IPC interface, external applications can configure, | |
345 | control and monitor the IKE daemon. Instead of scripting the ipsec tool | |
346 | and generating ipsec.conf, third party applications can use the new interface | |
347 | for more control and better reliability. | |
348 | ||
b30c09ea MW |
349 | - Built upon the libvici client library, swanctl implements the first user of |
350 | the VICI interface. Together with a swanctl.conf configuration file, | |
351 | connections can be defined, loaded and managed. swanctl provides a portable, | |
352 | complete IKE configuration and control interface for the command line. | |
73303700 | 353 | The first six swanctl example scenarios have been added. |

355 | - The SWID IMV implements a JSON-based REST API which allows the exchange |
356 | of SWID tags and Software IDs with the strongTNC policy manager. | |
357 | ||
37cb91d7 | 358 | - The SWID IMC can extract all installed packages from the dpkg (Debian, |
3d2b36b8 TB |
359 | Ubuntu, Linux Mint etc.), rpm (Fedora, RedHat, OpenSUSE, etc.), or |
360 | pacman (Arch Linux, Manjaro, etc.) package managers, respectively, using the | |
361 | swidGenerator (https://github.com/strongswan/swidGenerator) which generates | |
362 | SWID tags according to the new ISO/IEC 19770-2:2014 standard. | |
37cb91d7 AS |
363 | |
364 | - All IMVs now share the access requestor ID, device ID and product info | |
365 | of an access requestor via a common imv_session object. | |

382 | ||
e59ce07b TB |
383 | - Fixed an authentication bypass vulnerability triggered by rekeying an |
384 | unestablished IKEv2 SA while it gets actively initiated. This allowed an | |
385 | attacker to trick a peer's IKE_SA state to established, without the need to | |
386 | provide any valid authentication credentials. The vulnerability has been | |
387 | registered as CVE-2014-2338. | |
388 | ||
8101e6aa MW |
389 | - The acert plugin evaluates X.509 Attribute Certificates. Group membership |
390 | information encoded as strings can be used to fulfill authorization checks | |
391 | defined with the rightgroups option. Attribute Certificates can be loaded | |
392 | locally or get exchanged in IKEv2 certificate payloads. | |
393 | ||
394 | - The pki command gained support to generate X.509 Attribute Certificates | |
395 | using the --acert subcommand, while the --print command supports the ac type. | |
396 | The openac utility has been removed in favor of the new pki functionality. | |
397 | ||
7dc7fdea MW |
398 | - The libtls TLS 1.2 implementation as used by EAP-(T)TLS and other protocols |
399 | has been extended by AEAD mode support, currently limited to AES-GCM. | |

402 | strongswan-5.1.2 |
403 | ---------------- | |
404 | ||
c2d5add6 TB |
405 | - A new default configuration file layout is introduced. The new default |
406 | strongswan.conf file mainly includes config snippets from the strongswan.d | |
407 | and strongswan.d/charon directories (the latter containing snippets for all | |
408 | plugins). The snippets, with commented defaults, are automatically | |
409 | generated and installed, if they don't exist yet. They are also installed | |
410 | in $prefix/share/strongswan/templates so existing files can be compared to | |
411 | the current defaults. | |
412 | ||
413 | - As an alternative to the non-extensible charon.load setting, the plugins | |
414 | to load in charon (and optionally other applications) can now be determined | |
415 | via the charon.plugins.<name>.load setting for each plugin (enabled in the | |
416 | new default strongswan.conf file via the charon.load_modular option). | |
417 | The load setting optionally takes a numeric priority value that allows | |
418 | reordering the plugins (otherwise the default plugin order is preserved). | |
419 | ||
420 | - All strongswan.conf settings that were formerly defined in library specific | |
421 | "global" sections are now application specific (e.g. settings for plugins in | |
422 | libstrongswan.plugins can now be set only for charon in charon.plugins). | |
423 | The old options are still supported, which now allows to define defaults for | |
424 | all applications in the libstrongswan section. | |
425 | ||
acc25f29 AS |
426 | - The ntru libstrongswan plugin supports NTRUEncrypt as a post-quantum |
427 | computer IKE key exchange mechanism. The implementation is based on the | |
428 | ntru-crypto library from the NTRUOpenSourceProject. The supported security | |
429 | strengths are ntru112, ntru128, ntru192, and ntru256. Since the private DH | |
430 | group IDs 1030..1033 have been assigned, the strongSwan Vendor ID must be | |
431 | sent (charon.send_vendor_id = yes) in order to use NTRU. | |
432 | ||
800b361e AS |
433 | - Defined a TPMRA remote attestation workitem and added support for it to the |
434 | Attestation IMV. | |
435 | ||
c2d5add6 TB |
436 | - Compatibility issues between IPComp (compress=yes) and leftfirewall=yes as |
437 | well as multiple subnets in left|rightsubnet have been fixed. | |
438 | ||
572582f5 MW |
439 | - When enabling its "session" strongswan.conf option, the xauth-pam plugin opens |
440 | and closes a PAM session for each established IKE_SA. Patch courtesy of | |
441 | Andrea Bonomi. | |
acc25f29 | 442 | |
0cec570a MW |
443 | - The strongSwan unit testing framework has been rewritten without the "check" |
444 | dependency for improved flexibility and portability. It now properly supports | |
445 | multi-threaded and memory leak testing and brings a bunch of new test cases. | |
446 | ||
447 | ||
2b32884d AS |
448 | strongswan-5.1.1 |
449 | ---------------- | |
450 | ||
7b8fbd74 AS |
451 | - Fixed a denial-of-service vulnerability and potential authorization bypass |
452 | triggered by a crafted ID_DER_ASN1_DN ID payload. The cause is an insufficient | |
453 | length check when comparing such identities. The vulnerability has been | |
454 | registered as CVE-2013-6075. | |
455 | ||
456 | - Fixed a denial-of-service vulnerability triggered by a crafted IKEv1 | |
457 | fragmentation payload. The cause is a NULL pointer dereference. The | |
458 | vulnerability has been registered as CVE-2013-6076. | |
459 | ||
2b32884d | 460 | - The lean stand-alone pt-tls-client can set up a RFC 6876 PT-TLS session |
1c1ba803 TB |
461 | with a strongSwan policy enforcement point which uses the tnc-pdp charon |
462 | plugin. | |
2b32884d | 463 | |
fa2f6aa1 AS |
464 | - The new TCG TNC SWID IMC/IMV pair supports targeted SWID requests for either |
465 | full SWID Tag or concise SWID Tag ID inventories. | |
466 | ||
38fb8e4e MW |
467 | - The XAuth backend in eap-radius now supports multiple XAuth exchanges for |
468 | different credential types and display messages. All user input gets | |
469 | concatenated and verified with a single User-Password RADIUS attribute on | |
470 | the AAA. With an AAA supporting it, one for example can implement | |
471 | Password+Token authentication with proper dialogs on iOS and OS X clients. | |
472 | ||
473 | - charon supports IKEv1 Mode Config exchange in push mode. The ipsec.conf | |
474 | modeconfig=push option enables it for both client and server, the same way | |
475 | as pluto used it. | |
476 | ||
390d2b50 MW |
477 | - Using the "ah" ipsec.conf keyword on both IKEv1 and IKEv2 connections, |
478 | charon can negotiate and install Security Associations integrity-protected by | |
479 | the Authentication Header protocol. Supported are plain AH(+IPComp) SAs only, | |
480 | but not the deprecated RFC2401 style ESP+AH bundles. | |
481 | ||
1c1ba803 TB |
482 | - The generation of initialization vectors for IKE and ESP (when using libipsec) |
483 | is now modularized and IVs for e.g. AES-GCM are now correctly allocated | |
484 | sequentially, while other algorithms like AES-CBC still use random IVs. | |
485 | ||
38fb8e4e MW |
486 | - The left and right options in ipsec.conf can take multiple address ranges |
487 | and subnets. This allows connection matching against a larger set of | |
488 | addresses, for example to use a different connection for clients connecting | |
489 | from a internal network. | |
490 | ||
34dff30c AS |
491 | - For all those who have a queasy feeling about the NIST elliptic curve set, |
492 | the Brainpool curves introduced for use with IKE by RFC 6932 might be a | |
493 | more trustworthy alternative. | |
494 | ||
390d2b50 MW |
495 | - The kernel-libipsec userland IPsec backend now supports usage statistics, |
496 | volume based rekeying and accepts ESPv3 style TFC padded packets. | |
497 | ||
1c1ba803 TB |
498 | - With two new strongswan.conf options fwmarks can be used to implement |
499 | host-to-host tunnels with kernel-libipsec. | |
500 | ||
38fb8e4e MW |
501 | - load-tester supports transport mode connections and more complex traffic |
502 | selectors, including such using unique ports for each tunnel. | |
2b32884d | 503 | |
1c1ba803 TB |
504 | - The new dnscert plugin provides support for authentication via CERT RRs that |
505 | are protected via DNSSEC. The plugin was created by Ruslan N. Marchenko. | |
506 | ||
507 | - The eap-radius plugin supports forwarding of several Cisco Unity specific | |
508 | RADIUS attributes in corresponding configuration payloads. | |
509 | ||
510 | - Database transactions are now abstracted and implemented by the two backends. | |
511 | If you use MySQL make sure all tables use the InnoDB engine. | |
512 | ||
390d2b50 MW |
513 | - libstrongswan now can provide an experimental custom implementation of the |
514 | printf family functions based on klibc if neither Vstr nor glibc style printf | |
515 | hooks are available. This can avoid the Vstr dependency on some systems at | |
516 | the cost of slower and less complete printf functions. | |
517 | ||
fa2f6aa1 | 518 | |
40b0a15c MW |
519 | strongswan-5.1.0 |
520 | ---------------- | |
521 | ||
3a938a6f TB |
522 | - Fixed a denial-of-service vulnerability triggered by specific XAuth usernames |
523 | and EAP identities (since 5.0.3), and PEM files (since 4.1.11). The crash | |
524 | was caused by insufficient error handling in the is_asn1() function. | |
525 | The vulnerability has been registered as CVE-2013-5018. | |
526 | ||
40b0a15c MW |
527 | - The new charon-cmd command line IKE client can establish road warrior |
528 | connections using IKEv1 or IKEv2 with different authentication profiles. | |
529 | It does not depend on any configuration files and can be configured using a | |
530 | few simple command line options. | |
531 | ||
532 | - The kernel-pfroute networking backend has been greatly improved. It now | |
78e6f69e | 533 | can install virtual IPs on TUN devices on OS X and FreeBSD, allowing these |
40b0a15c MW |
534 | systems to act as a client in common road warrior scenarios. |
535 | ||
78e6f69e TB |
536 | - The new kernel-libipsec plugin uses TUN devices and libipsec to provide IPsec |
537 | processing in userland on Linux, FreeBSD and Mac OS X. | |
538 | ||
68957d18 MW |
539 | - The eap-radius plugin can now serve as an XAuth backend called xauth-radius, |
540 | directly verifying XAuth credentials using RADIUS User-Name/User-Password | |
541 | attributes. This is more efficient than the existing xauth-eap+eap-radius | |
542 | combination, and allows RADIUS servers without EAP support to act as AAA | |
543 | backend for IKEv1. | |
544 | ||
78e6f69e | 545 | - The new osx-attr plugin installs configuration attributes (currently DNS |
2334ae56 MW |
546 | servers) via SystemConfiguration on Mac OS X. The keychain plugin provides |
547 | certificates from the OS X keychain service. | |
78e6f69e TB |
548 | |
549 | - The sshkey plugin parses SSH public keys, which, together with the --agent | |
550 | option for charon-cmd, allows the use of ssh-agent for authentication. | |
551 | To configure SSH keys in ipsec.conf the left|rightrsasigkey options are | |
552 | replaced with left|rightsigkey, which now take public keys in one of three | |
553 | formats: SSH (RFC 4253, ssh: prefix), DNSKEY (RFC 3110, dns: prefix), and | |
554 | PKCS#1 (the default, no prefix). | |
555 | ||
556 | - Extraction of certificates and private keys from PKCS#12 files is now provided | |
557 | by the new pkcs12 plugin or the openssl plugin. charon-cmd (--p12) as well | |
558 | as charon (via P12 token in ipsec.secrets) can make use of this. | |
559 | ||
40b0a15c MW |
560 | - IKEv2 can now negotiate transport mode and IPComp in NAT situations. |
561 | ||
3a938a6f | 562 | - IKEv2 exchange initiators now properly close an established IKE or CHILD_SA |
40b0a15c MW |
563 | on error conditions using an additional exchange, keeping state in sync |
564 | between peers. | |
565 | ||
226f34e0 | 566 | - Using a SQL database interface a Trusted Network Connect (TNC) Policy Manager |
78e6f69e TB |
567 | can generate specific measurement workitems for an arbitrary number of |
568 | Integrity Measurement Verifiers (IMVs) based on the history of the VPN user | |
569 | and/or device. | |
570 | ||
571 | - Several core classes in libstrongswan are now tested with unit tests. These | |
572 | can be enabled with --enable-unit-tests and run with 'make check'. Coverage | |
573 | reports can be generated with --enable-coverage and 'make coverage' (this | |
574 | disables any optimization, so it should not be enabled when building | |
575 | production releases). | |
576 | ||
56b753ca MW |
577 | - The leak-detective developer tool has been greatly improved. It works much |
578 | faster/stabler with multiple threads, does not use deprecated malloc hooks | |
579 | anymore and has been ported to OS X. | |
580 | ||
78e6f69e TB |
581 | - chunk_hash() is now based on SipHash-2-4 with a random key. This provides |
582 | better distribution and prevents hash flooding attacks when used with | |
583 | hashtables. | |
584 | ||
585 | - All default plugins implement the get_features() method to define features | |
586 | and their dependencies. The plugin loader has been improved, so that plugins | |
587 | in a custom load statement can be ordered freely or to express preferences | |
588 | without being affected by dependencies between plugin features. | |
589 | ||
c3b8335c MW |
590 | - A centralized thread can take care for watching multiple file descriptors |
591 | concurrently. This removes the need for a dedicated listener threads in | |
592 | various plugins. The number of "reserved" threads for such tasks has been | |
593 | reduced to about five, depending on the plugin configuration. | |
594 | ||
595 | - Plugins that can be controlled by a UNIX socket IPC mechanism gained network | |
596 | transparency. Third party applications querying these plugins now can use | |
597 | TCP connections from a different host. | |
598 | ||
78e6f69e | 599 | - libipsec now supports AES-GCM. |
226f34e0 | 600 | |
40b0a15c | 601 | |
2e12fc4b AS |
602 | strongswan-5.0.4 |
603 | ---------------- | |
604 | ||
605 | - Fixed a security vulnerability in the openssl plugin which was reported by | |
606 | Kevin Wojtysiak. The vulnerability has been registered as CVE-2013-2944. | |
607 | Before the fix, if the openssl plugin's ECDSA signature verification was used, | |
608 | due to a misinterpretation of the error code returned by the OpenSSL | |
609 | ECDSA_verify() function, an empty or zeroed signature was accepted as a | |
610 | legitimate one. | |
611 | ||
612 | - The handling of a couple of other non-security relevant openssl return codes | |
613 | was fixed as well. | |
614 | ||
615 | - The tnc_ifmap plugin now publishes virtual IPv4 and IPv6 addresses via its | |
616 | TCG TNC IF-MAP 2.1 interface. | |
617 | ||
618 | - The charon.initiator_only option causes charon to ignore IKE initiation | |
619 | requests. | |
620 | ||
bec5bf02 AS |
621 | - The openssl plugin can now use the openssl-fips library. |
622 | ||
2e12fc4b | 623 | |
d69eb037 TB |
624 | strongswan-5.0.3 |
625 | ---------------- | |
626 | ||
627 | - The new ipseckey plugin enables authentication based on trustworthy public | |
628 | keys stored as IPSECKEY resource records in the DNS and protected by DNSSEC. | |
629 | To do so it uses a DNSSEC enabled resolver, like the one provided by the new | |
630 | unbound plugin, which is based on libldns and libunbound. Both plugins were | |
631 | created by Reto Guadagnini. | |
632 | ||
1fc609fe AS |
633 | - Implemented the TCG TNC IF-IMV 1.4 draft making access requestor identities |
634 | available to an IMV. The OS IMV stores the AR identity together with the | |
635 | device ID in the attest database. | |
636 | ||
637 | - The openssl plugin now uses the AES-NI accelerated version of AES-GCM | |
638 | if the hardware supports it. | |
7a93844f | 639 | |
96776d6f MW |
640 | - The eap-radius plugin can now assign virtual IPs to IKE clients using the |
641 | Framed-IP-Address attribute by using the "%radius" named pool in the | |
642 | rightsourceip ipsec.conf option. Cisco Banner attributes are forwarded to | |
643 | Unity-capable IKEv1 clients during mode config. charon now sends Interim | |
644 | Accounting updates if requested by the RADIUS server, reports | |
645 | sent/received packets in Accounting messages, and adds a Terminate-Cause | |
646 | to Accounting-Stops. | |
647 | ||
648 | - The recently introduced "ipsec listcounters" command can report connection | |
649 | specific counters by passing a connection name, and global or connection | |
650 | counters can be reset by the "ipsec resetcounters" command. | |
651 | ||
652 | - The strongSwan libpttls library provides an experimental implementation of | |
653 | PT-TLS (RFC 6876), a Posture Transport Protocol over TLS. | |
654 | ||
655 | - The charon systime-fix plugin can disable certificate lifetime checks on | |
656 | embedded systems if the system time is obviously out of sync after bootup. | |
657 | Certificates lifetimes get checked once the system time gets sane, closing | |
658 | or reauthenticating connections using expired certificates. | |
659 | ||
660 | - The "ikedscp" ipsec.conf option can set DiffServ code points on outgoing | |
661 | IKE packets. | |
7a93844f | 662 | |
e34666a4 TB |
663 | - The new xauth-noauth plugin allows to use basic RSA or PSK authentication with |
664 | clients that cannot be configured without XAuth authentication. The plugin | |
665 | simply concludes the XAuth exchange successfully without actually performing | |
666 | any authentication. Therefore, to use this backend it has to be selected | |
667 | explicitly with rightauth2=xauth-noauth. | |
668 | ||
db50a35a RB |
669 | - The new charon-tkm IKEv2 daemon delegates security critical operations to a |
670 | separate process. This has the benefit that the network facing daemon has no | |
671 | knowledge of keying material used to protect child SAs. Thus subverting | |
672 | charon-tkm does not result in the compromise of cryptographic keys. | |
673 | The extracted functionality has been implemented from scratch in a minimal TCB | |
674 | (trusted computing base) in the Ada programming language. Further information | |
675 | can be found at http://www.codelabs.ch/tkm/. | |
676 | ||
c2a5e7bc AS |
677 | strongswan-5.0.2 |
678 | ---------------- | |
679 | ||
680 | - Implemented all IETF Standard PA-TNC attributes and an OS IMC/IMV | |
681 | pair using them to transfer operating system information. | |
682 | ||
a19d5913 MW |
683 | - The new "ipsec listcounters" command prints a list of global counter values |
684 | about received and sent IKE messages and rekeyings. | |
685 | ||
343e9989 MW |
686 | - A new lookip plugin can perform fast lookup of tunnel information using a |
687 | clients virtual IP and can send notifications about established or deleted | |
688 | tunnels. The "ipsec lookip" command can be used to query such information | |
689 | or receive notifications. | |
690 | ||
ecdd5aed MW |
691 | - The new error-notify plugin catches some common error conditions and allows |
692 | an external application to receive notifications for them over a UNIX socket. | |
693 | ||
6910e5c7 MW |
694 | - IKE proposals can now use a PRF algorithm different to that defined for |
695 | integrity protection. If an algorithm with a "prf" prefix is defined | |
696 | explicitly (such as prfsha1 or prfsha256), no implicit PRF algorithm based on | |
697 | the integrity algorithm is added to the proposal. | |
c2a5e7bc | 698 | |
8fc7bbc6 MW |
699 | - The pkcs11 plugin can now load leftcert certificates from a smartcard for a |
700 | specific ipsec.conf conn section and cacert CA certificates for a specific ca | |
701 | section. | |
702 | ||
78b2a2b1 MW |
703 | - The load-tester plugin gained additional options for certificate generation |
704 | and can load keys and multiple CA certificates from external files. It can | |
705 | install a dedicated outer IP address for each tunnel and tunnel initiation | |
706 | batches can be triggered and monitored externally using the | |
707 | "ipsec load-tester" tool. | |
708 | ||
cc0cc3b5 MW |
709 | - PKCS#7 container parsing has been modularized, and the openssl plugin |
710 | gained an alternative implementation to decrypt and verify such files. | |
711 | In contrast to our own DER parser, OpenSSL can handle BER files, which is | |
712 | required for interoperability of our scepclient with EJBCA. | |
713 | ||
f31b4180 TB |
714 | - Support for the proprietary IKEv1 fragmentation extension has been added. |
715 | Fragments are always handled on receipt but only sent if supported by the peer | |
716 | and if enabled with the new fragmentation ipsec.conf option. | |
717 | ||
0e0870ae MW |
718 | - IKEv1 in charon can now parse certificates received in PKCS#7 containers and |
719 | supports NAT traversal as used by Windows clients. Patches courtesy of | |
720 | Volker Rümelin. | |
721 | ||
2f0441a3 MW |
722 | - The new rdrand plugin provides a high quality / high performance random |
723 | source using the Intel rdrand instruction found on Ivy Bridge processors. | |
724 | ||
73791223 TB |
725 | - The integration test environment was updated and now uses KVM and reproducible |
726 | guest images based on Debian. | |
727 | ||
1fc609fe | 728 | |
ecfd714c AS |
729 | strongswan-5.0.1 |
730 | ---------------- | |
731 | ||
6f93927b AS |
732 | - Introduced the sending of the standard IETF Assessment Result |
733 | PA-TNC attribute by all strongSwan Integrity Measurement Verifiers. | |
734 | ||
ecfd714c AS |
735 | - Extended PTS Attestation IMC/IMV pair to provide full evidence of |
736 | the Linux IMA measurement process. All pertinent file information | |
6f93927b | 737 | of a Linux OS can be collected and stored in an SQL database. |
ecfd714c AS |
738 | |
739 | - The PA-TNC and PB-TNC protocols can now process huge data payloads | |
740 | >64 kB by distributing PA-TNC attributes over multiple PA-TNC messages | |
741 | and these messages over several PB-TNC batches. As long as no | |
6f93927b | 742 | consolidated recommandation from all IMVs can be obtained, the TNC |
ecfd714c AS |
743 | server requests more client data by sending an empty SDATA batch. |
744 | ||
804d702b MW |
745 | - The rightgroups2 ipsec.conf option can require group membership during |
746 | a second authentication round, for example during XAuth authentication | |
747 | against a RADIUS server. | |
748 | ||
3423b3a8 MW |
749 | - The xauth-pam backend can authenticate IKEv1 XAuth and Hybrid authenticated |
750 | clients against any PAM service. The IKEv2 eap-gtc plugin does not use | |
751 | PAM directly anymore, but can use any XAuth backend to verify credentials, | |
752 | including xauth-pam. | |
753 | ||
cc48f360 MW |
754 | - The new unity plugin brings support for some parts of the IKEv1 Cisco Unity |
755 | Extension. As client, charon narrows traffic selectors to the received | |
756 | Split-Include attributes and automatically installs IPsec bypass policies | |
757 | for received Local-LAN attributes. As server, charon sends Split-Include | |
758 | attributes for leftsubnet definitions containing multiple subnets to Unity- | |
759 | aware clients. | |
760 | ||
cbe244a5 TB |
761 | - An EAP-Nak payload is returned by clients if the gateway requests an EAP |
762 | method that the client does not support. Clients can also request a specific | |
763 | EAP method by configuring that method with leftauth. | |
764 | ||
765 | - The eap-dynamic plugin handles EAP-Nak payloads returned by clients and uses | |
766 | these to select a different EAP method supported/requested by the client. | |
767 | The plugin initially requests the first registered method or the first method | |
768 | configured with charon.plugins.eap-dynamic.preferred. | |
769 | ||
e76f3d0d MW |
770 | - The new left/rightdns options specify connection specific DNS servers to |
771 | request/respond in IKEv2 configuration payloads or IKEv2 mode config. leftdns | |
772 | can be any (comma separated) combination of %config4 and %config6 to request | |
773 | multiple servers, both for IPv4 and IPv6. rightdns takes a list of DNS server | |
774 | IP addresses to return. | |
775 | ||
69e056a2 MW |
776 | - The left/rightsourceip options now accept multiple addresses or pools. |
777 | leftsourceip can be any (comma separated) combination of %config4, %config6 | |
778 | or fixed IP addresses to request. rightsourceip accepts multiple explicitly | |
779 | specified or referenced named pools. | |
780 | ||
781 | - Multiple connections can now share a single address pool when they use the | |
782 | same definition in one of the rightsourceip pools. | |
783 | ||
4a025539 TB |
784 | - The options charon.interfaces_ignore and charon.interfaces_use allow one to |
785 | configure the network interfaces used by the daemon. | |
786 | ||
787 | - The kernel-netlink plugin supports the charon.install_virtual_ip_on option, | |
788 | which specifies the interface on which virtual IP addresses will be installed. | |
789 | If it is not specified the current behavior of using the outbound interface | |
790 | is preserved. | |
791 | ||
792 | - The kernel-netlink plugin tries to keep the current source address when | |
793 | looking for valid routes to reach other hosts. | |
794 | ||
804d702b MW |
795 | - The autotools build has been migrated to use a config.h header. strongSwan |
796 | development headers will get installed during "make install" if | |
797 | --with-dev-headers has been passed to ./configure. | |
798 | ||
799 | - All crypto primitives gained return values for most operations, allowing | |
800 | crypto backends to fail, for example when using hardware accelerators. | |

803 | strongswan-5.0.0 |
804 | ---------------- | |
805 | ||
794cdbc5 MW |
806 | - The charon IKE daemon gained experimental support for the IKEv1 protocol. |
807 | Pluto has been removed from the 5.x series, and unless strongSwan is | |
808 | configured with --disable-ikev1 or --disable-ikev2, charon handles both | |
809 | keying protocols. The feature-set of IKEv1 in charon is almost on par with | |
810 | pluto, but currently does not support AH or bundled AH+ESP SAs. Beside | |
811 | RSA/ECDSA, PSK and XAuth, charon also supports the Hybrid authentication | |
812 | mode. Informations for interoperability and migration is available at | |
813 | http://wiki.strongswan.org/projects/strongswan/wiki/CharonPlutoIKEv1. | |
814 | ||
d55c2404 TB |
815 | - Charon's bus_t has been refactored so that loggers and other listeners are |
816 | now handled separately. The single lock was previously cause for deadlocks | |
817 | if extensive listeners, such as the one provided by the updown plugin, wanted | |
818 | to acquire locks that were held by other threads which in turn tried to log | |
819 | messages, and thus were waiting to acquire the same lock currently held by | |
820 | the thread calling the listener. | |
821 | The implemented changes also allow the use of a read/write-lock for the | |
822 | loggers which increases performance if multiple loggers are registered. | |
823 | Besides several interface changes this last bit also changes the semantics | |
824 | for loggers as these may now be called by multiple threads at the same time. | |
825 | ||
ed7186cb TB |
826 | - Source routes are reinstalled if interfaces are reactivated or IP addresses |
827 | reappear. | |
828 | ||
f97c269e TB |
829 | - The thread pool (processor_t) now has more control over the lifecycle of |
830 | a job (see job.h for details). In particular, it now controls the destruction | |
831 | of jobs after execution and the cancellation of jobs during shutdown. Due to | |
832 | these changes the requeueing feature, previously available to callback_job_t | |
833 | only, is now available to all jobs (in addition to a new rescheduling | |
834 | feature). | |
835 | ||
5a6e5e0d MW |
836 | - In addition to trustchain key strength definitions for different public key |
837 | systems, the rightauth option now takes a list of signature hash algorithms | |
838 | considered save for trustchain validation. For example, the setting | |
839 | rightauth=rsa-2048-ecdsa-256-sha256-sha384-sha512 requires a trustchain | |
840 | that uses at least RSA-2048 or ECDSA-256 keys and certificate signatures | |
841 | using SHA-256 or better. | |
842 | ||

93d9a02e TB |
844 | strongswan-4.6.4 |
845 | ---------------- | |
846 | ||
847 | - Fixed a security vulnerability in the gmp plugin. If this plugin was used | |
848 | for RSA signature verification an empty or zeroed signature was handled as | |
849 | a legitimate one. | |
850 | ||
851 | - Fixed several issues with reauthentication and address updates. | |
852 | ||
853 | ||
c224f765 AS |
854 | strongswan-4.6.3 |
855 | ---------------- | |
856 | ||
857 | - The tnc-pdp plugin implements a RADIUS server interface allowing | |
858 | a strongSwan TNC server to act as a Policy Decision Point. | |
859 | ||
4bc7577d MW |
860 | - The eap-radius authentication backend enforces Session-Timeout attributes |
861 | using RFC4478 repeated authentication and acts upon RADIUS Dynamic | |
862 | Authorization extensions, RFC 5176. Currently supported are disconnect | |
863 | requests and CoA messages containing a Session-Timeout. | |
864 | ||
865 | - The eap-radius plugin can forward arbitrary RADIUS attributes from and to | |
866 | clients using custom IKEv2 notify payloads. The new radattr plugin reads | |
867 | attributes to include from files and prints received attributes to the | |
868 | console. | |
c224f765 AS |
869 | |
870 | - Added support for untruncated MD5 and SHA1 HMACs in ESP as used in | |
871 | RFC 4595. | |
872 | ||
d7590217 TB |
873 | - The cmac plugin implements the AES-CMAC-96 and AES-CMAC-PRF-128 algorithms |
874 | as defined in RFC 4494 and RFC 4615, respectively. | |
875 | ||
4e2e77d5 | 876 | - The resolve plugin automatically installs nameservers via resolvconf(8), |
a281494a | 877 | if it is installed, instead of modifying /etc/resolv.conf directly. |
c224f765 | 878 | |
5f1931ad AS |
879 | - The IKEv2 charon daemon supports now raw RSA public keys in RFC 3110 |
880 | DNSKEY and PKCS#1 file format. | |
881 | ||
882 | ||
60e99b37 AS |
883 | strongswan-4.6.2 |
884 | ---------------- | |
885 | ||
886 | - Upgraded the TCG IF-IMC and IF-IMV C API to the upcoming version 1.3 | |
887 | which supports IF-TNCCS 2.0 long message types, the exclusive flags | |
888 | and multiple IMC/IMV IDs. Both the TNC Client and Server as well as | |
889 | the "Test", "Scanner", and "Attestation" IMC/IMV pairs were updated. | |
890 | ||
891 | - Fully implemented the "TCG Attestation PTS Protocol: Binding to IF-M" | |
892 | standard (TLV-based messages only). TPM-based remote attestation of | |
de4a0c83 AS |
893 | Linux IMA (Integrity Measurement Architecture) possible. Measurement |
894 | reference values are automatically stored in an SQLite database. | |
60e99b37 | 895 | |
a345aa26 MW |
896 | - The EAP-RADIUS authentication backend supports RADIUS accounting. It sends |
897 | start/stop messages containing Username, Framed-IP and Input/Output-Octets | |
898 | attributes and has been tested against FreeRADIUS and Microsoft NPS. | |
60e99b37 | 899 | |
de4a0c83 AS |
900 | - Added support for PKCS#8 encoded private keys via the libstrongswan |
901 | pkcs8 plugin. This is the default format used by some OpenSSL tools since | |
902 | version 1.0.0 (e.g. openssl req with -keyout). | |
dcefa267 | 903 | |
a8958012 MW |
904 | - Added session resumption support to the strongSwan TLS stack. |
905 | ||
de4a0c83 | 906 | |
acb92cb4 AS |
907 | strongswan-4.6.1 |
908 | ---------------- | |
909 | ||
910 | - Because of changing checksums before and after installation which caused | |
911 | the integrity tests to fail we avoided directly linking libsimaka, libtls and | |
912 | libtnccs to those libcharon plugins which make use of these dynamic libraries. | |
18f85b66 AS |
913 | Instead we linked the libraries to the charon daemon. Unfortunately Ubuntu |
914 | 11.10 activated the --as-needed ld option which discards explicit links | |
915 | to dynamic libraries that are not actually used by the charon daemon itself, | |
916 | thus causing failures during the loading of the plugins which depend on these | |
917 | libraries for resolving external symbols. | |
acb92cb4 AS |
918 | |
919 | - Therefore our approach of computing integrity checksums for plugins had to be | |
920 | changed radically by moving the hash generation from the compilation to the | |
921 | post-installation phase. | |

5a2e2e0b AS |
925 | ---------------- |
926 | ||
37276728 MW |
927 | - The new libstrongswan certexpire plugin collects expiration information of |
928 | all used certificates and exports them to CSV files. It either directly | |
929 | exports them or uses cron style scheduling for batch exports. | |
930 | ||
931 | - starter passes unresolved hostnames to charon, allowing it to do name | |
932 | resolution not before the connection attempt. This is especially useful with | |
933 | connections between hosts using dynamic IP addresses. Thanks to Mirko Parthey | |
934 | for the initial patch. | |
935 | ||
5fd8e530 TB |
936 | - The android plugin can now be used without the Android frontend patch and |
937 | provides DNS server registration and logging to logcat. | |
938 | ||
939 | - Pluto and starter (plus stroke and whack) have been ported to Android. | |
940 | ||
602ee58e TB |
941 | - Support for ECDSA private and public key operations has been added to the |
942 | pkcs11 plugin. The plugin now also provides DH and ECDH via PKCS#11 and can | |
943 | use tokens as random number generators (RNG). By default only private key | |
944 | operations are enabled, more advanced features have to be enabled by their | |
945 | option in strongswan.conf. This also applies to public key operations (even | |
946 | for keys not stored on the token) which were enabled by default before. | |
947 | ||
37276728 MW |
948 | - The libstrongswan plugin system now supports detailed plugin dependencies. |
949 | Many plugins have been extended to export its capabilities and requirements. | |
950 | This allows the plugin loader to resolve plugin loading order automatically, | |
951 | and in future releases, to dynamically load the required features on demand. | |
952 | Existing third party plugins are source (but not binary) compatible if they | |
953 | properly initialize the new get_features() plugin function to NULL. | |
954 | ||
fd81ac05 AS |
955 | - The tnc-ifmap plugin implements a TNC IF-MAP 2.0 client which can deliver |
956 | metadata about IKE_SAs via a SOAP interface to a MAP server. The tnc-ifmap | |
957 | plugin requires the Apache Axis2/C library. | |
958 | ||
37276728 | 959 | |
5d179d19 AS |
960 | strongswan-4.5.3 |
961 | ---------------- | |
962 | ||
a7edbd21 | 963 | - Our private libraries (e.g. libstrongswan) are not installed directly in |
b18a697a AS |
964 | prefix/lib anymore. Instead a subdirectory is used (prefix/lib/ipsec/ by |
965 | default). The plugins directory is also moved from libexec/ipsec/ to that | |
a7edbd21 TB |
966 | directory. |
967 | ||
b18a697a AS |
968 | - The dynamic IMC/IMV libraries were moved from the plugins directory to |
969 | a new imcvs directory in the prefix/lib/ipsec/ subdirectory. | |
970 | ||
107ea60f TB |
971 | - Job priorities were introduced to prevent thread starvation caused by too |
972 | many threads handling blocking operations (such as CRL fetching). Refer to | |
973 | strongswan.conf(5) for details. | |
974 | ||
975 | - Two new strongswan.conf options allow to fine-tune performance on IKEv2 | |
976 | gateways by dropping IKE_SA_INIT requests on high load. | |
977 | ||
f8799170 | 978 | - IKEv2 charon daemon supports start PASS and DROP shunt policies |
b18a697a | 979 | preventing traffic to go through IPsec connections. Installation of the |
107ea60f TB |
980 | shunt policies either via the XFRM netfilter or PFKEYv2 IPsec kernel |
981 | interfaces. | |
f8799170 | 982 | |
93095183 TB |
983 | - The history of policies installed in the kernel is now tracked so that e.g. |
984 | trap policies are correctly updated when reauthenticated SAs are terminated. | |
985 | ||
b18a697a AS |
986 | - IMC/IMV Scanner pair implementing the RFC 5792 PA-TNC (IF-M) protocol. |
987 | Using "netstat -l" the IMC scans open listening ports on the TNC client | |
988 | and sends a port list to the IMV which based on a port policy decides if | |
989 | the client is admitted to the network. | |
990 | (--enable-imc-scanner/--enable-imv-scanner). | |
991 | ||
992 | - IMC/IMV Test pair implementing the RFC 5792 PA-TNC (IF-M) protocol. | |
5d179d19 AS |
993 | (--enable-imc-test/--enable-imv-test). |
994 | ||
4876f896 MW |
995 | - The IKEv2 close action does not use the same value as the ipsec.conf dpdaction |
996 | setting, but the value defined by its own closeaction keyword. The action | |
997 | is triggered if the remote peer closes a CHILD_SA unexpectedly. | |
5d179d19 | 998 | |
5a2e2e0b | 999 | |
6f2378c1 AS |
1000 | strongswan-4.5.2 |
1001 | ---------------- | |
1002 | ||
320e98c2 MW |
1003 | - The whitelist plugin for the IKEv2 daemon maintains an in-memory identity |
1004 | whitelist. Any connection attempt of peers not whitelisted will get rejected. | |
1005 | The 'ipsec whitelist' utility provides a simple command line frontend for | |
1006 | whitelist administration. | |
1007 | ||
92ebb7c5 | 1008 | - The duplicheck plugin provides a specialized form of duplicate checking, |
5832d505 | 1009 | doing a liveness check on the old SA and optionally notify a third party |
92ebb7c5 MW |
1010 | application about detected duplicates. |
1011 | ||
1012 | - The coupling plugin permanently couples two or more devices by limiting | |
1013 | authentication to previously used certificates. | |
1014 | ||
6f2378c1 AS |
1015 | - In the case that the peer config and child config don't have the same name |
1016 | (usually in SQL database defined connections), ipsec up|route <peer config> | |
1017 | starts|routes all associated child configs and ipsec up|route <child config> | |
1018 | only starts|routes the specific child config. | |
1019 | ||
6ca05fe2 AS |
1020 | - fixed the encoding and parsing of X.509 certificate policy statements (CPS). |
1021 | ||
1ee7440b AS |
1022 | - Duncan Salerno contributed the eap-sim-pcsc plugin implementing a |
1023 | pcsc-lite based SIM card backend. | |
1024 | ||
1025 | - The eap-peap plugin implements the EAP PEAP protocol. Interoperates | |
2778b664 | 1026 | successfully with a FreeRADIUS server and Windows 7 Agile VPN clients. |
1ee7440b | 1027 | |
cf6ca6d7 MW |
1028 | - The IKEv2 daemon charon rereads strongswan.conf on SIGHUP and instructs |
1029 | all plugins to reload. Currently only the eap-radius and the attr plugins | |
1030 | support configuration reloading. | |
1031 | ||
d3d21c29 MW |
1032 | - Added userland support to the IKEv2 daemon for Extended Sequence Numbers |
1033 | support coming with Linux 2.6.39. To enable ESN on a connection, add | |
1034 | the 'esn' keyword to the proposal. The default proposal uses 32-bit sequence | |
1035 | numbers only ('noesn'), and the same value is used if no ESN mode is | |
1036 | specified. To negotiate ESN support with the peer, include both, e.g. | |
1037 | esp=aes128-sha1-esn-noesn. | |
1038 | ||
1039 | - In addition to ESN, Linux 2.6.39 gained support for replay windows larger | |
1040 | than 32 packets. The new global strongswan.conf option 'charon.replay_window' | |
1041 | configures the size of the replay window, in packets. | |
1042 | ||
6f2378c1 | 1043 | |
41ba5ce7 AS |
1044 | strongswan-4.5.1 |
1045 | ---------------- | |
1046 | ||
1b7e081b AS |
1047 | - Sansar Choinyambuu implemented the RFC 5793 Posture Broker Protocol (BP) |
1048 | compatible with Trusted Network Connect (TNC). The TNCCS 2.0 protocol | |
5cdaafef | 1049 | requires the tnccs_20, tnc_imc and tnc_imv plugins but does not depend |
1b7e081b AS |
1050 | on the libtnc library. Any available IMV/IMC pairs conforming to the |
1051 | Trusted Computing Group's TNC-IF-IMV/IMC 1.2 interface specification | |
e44817df | 1052 | can be loaded via /etc/tnc_config. |
1b7e081b | 1053 | |
5cdaafef AS |
1054 | - Re-implemented the TNCCS 1.1 protocol by using the tnc_imc and tnc_imv |
1055 | in place of the external libtnc library. | |
1056 | ||
1057 | - The tnccs_dynamic plugin loaded on a TNC server in addition to the | |
1058 | tnccs_11 and tnccs_20 plugins, dynamically detects the IF-TNCCS | |
1059 | protocol version used by a TNC client and invokes an instance of | |
1060 | the corresponding protocol stack. | |
1061 | ||
41ba5ce7 AS |
1062 | - IKE and ESP proposals can now be stored in an SQL database using a |
1063 | new proposals table. The start_action field in the child_configs | |
1064 | tables allows the automatic starting or routing of connections stored | |
1065 | in an SQL database. | |
1066 | ||
1b7e081b AS |
1067 | - The new certificate_authorities and certificate_distribution_points |
1068 | tables make it possible to store CRL and OCSP Certificate Distribution | |
1069 | points in an SQL database. | |
1070 | ||
ae09bc62 TB |
1071 | - The new 'include' statement allows to recursively include other files in |
1072 | strongswan.conf. Existing sections and values are thereby extended and | |
1073 | replaced, respectively. | |
1074 | ||
1075 | - Due to the changes in the parser for strongswan.conf, the configuration | |
1076 | syntax for the attr plugin has changed. Previously, it was possible to | |
1077 | specify multiple values of a specific attribute type by adding multiple | |
1078 | key/value pairs with the same key (e.g. dns) to the plugins.attr section. | |
1079 | Because values with the same key now replace previously defined values | |
1080 | this is not possible anymore. As an alternative, multiple values can be | |
1081 | specified by separating them with a comma (e.g. dns = 1.2.3.4, 2.3.4.5). | |
1082 | ||
840e7044 AS |
1083 | - ipsec listalgs now appends (set in square brackets) to each crypto |
1084 | algorithm listed the plugin that registered the function. | |
1085 | ||
e44817df MW |
1086 | - Traffic Flow Confidentiality padding supported with Linux 2.6.38 can be used |
1087 | by the IKEv2 daemon. The ipsec.conf 'tfc' keyword pads all packets to a given | |
1088 | boundary, the special value '%mtu' pads all packets to the path MTU. | |
1089 | ||
78a547c9 MW |
1090 | - The new af-alg plugin can use various crypto primitives of the Linux Crypto |
1091 | API using the AF_ALG interface introduced with 2.6.38. This removes the need | |
1092 | for additional userland implementations of symmetric cipher, hash, hmac and | |
1093 | xcbc algorithms. | |
44582075 | 1094 | |
41ed0294 | 1095 | - The IKEv2 daemon supports the INITIAL_CONTACT notify as initiator and |
983a5e88 MW |
1096 | responder. The notify is sent when initiating configurations with a unique |
1097 | policy, set in ipsec.conf via the global 'uniqueids' option. | |
41ed0294 | 1098 | |
f0783464 MW |
1099 | - The conftest conformance testing framework enables the IKEv2 stack to perform |
1100 | many tests using a distinct tool and configuration frontend. Various hooks | |
1101 | can alter reserved bits, flags, add custom notifies and proposals, reorder | |
1102 | or drop messages and much more. It is enabled using the --enable-conftest | |
1103 | ./configure switch. | |
1104 | ||
77eee25f | 1105 | - The new libstrongswan constraints plugin provides advanced X.509 constraint |
cf95d292 | 1106 | checking. In addition to X.509 pathLen constraints, the plugin checks for |
77eee25f MW |
1107 | nameConstraints and certificatePolicies, including policyMappings and |
1108 | policyConstraints. The x509 certificate plugin and the pki tool have been | |
96c4addc MW |
1109 | enhanced to support these extensions. The new left/rightcertpolicy ipsec.conf |
1110 | connection keywords take OIDs a peer certificate must have. | |
1111 | ||
1112 | - The left/rightauth ipsec.conf keywords accept values with a minimum strength | |
1113 | for trustchain public keys in bits, such as rsa-2048 or ecdsa-256. | |
77eee25f | 1114 | |
fb1e7df1 MW |
1115 | - The revocation and x509 libstrongswan plugins and the pki tool gained basic |
1116 | support for delta CRLs. | |
1117 | ||

b14923ec AS |
1122 | - IMPORTANT: the default keyexchange mode 'ike' is changing with release 4.5 |
1123 | from 'ikev1' to 'ikev2', thus commemorating the five year anniversary of the | |
ac544be2 | 1124 | IKEv2 RFC 4306 and its mature successor RFC 5996. The time has definitively |
b14923ec | 1125 | come for IKEv1 to go into retirement and to cede its place to the much more |
ac544be2 | 1126 | robust, powerful and versatile IKEv2 protocol! |
b14923ec | 1127 | |
44582075 MW |
1128 | - Added new ctr, ccm and gcm plugins providing Counter, Counter with CBC-MAC |
1129 | and Galois/Counter Modes based on existing CBC implementations. These | |
1130 | new plugins bring support for AES and Camellia Counter and CCM algorithms | |
1131 | and the AES GCM algorithms for use in IKEv2. | |
1132 | ||
84c9bc42 MW |
1133 | - The new pkcs11 plugin brings full Smartcard support to the IKEv2 daemon and |
1134 | the pki utility using one or more PKCS#11 libraries. It currently supports | |
61df42cc | 1135 | RSA private and public key operations and loads X.509 certificates from |
84c9bc42 MW |
1136 | tokens. |
1137 | ||
a782b52f MW |
1138 | - Implemented a general purpose TLS stack based on crypto and credential |
1139 | primitives of libstrongswan. libtls supports TLS versions 1.0, 1.1 and 1.2, | |
1140 | ECDHE-ECDSA/RSA, DHE-RSA and RSA key exchange algorithms and RSA/ECDSA based | |
1141 | client authentication. | |
1142 | ||
1143 | - Based on libtls, the eap-tls plugin brings certificate based EAP | |
1144 | authentication for client and server. It is compatible to Windows 7 IKEv2 | |
61df42cc | 1145 | Smartcard authentication and the OpenSSL based FreeRADIUS EAP-TLS backend. |
a782b52f | 1146 | |
8a1353fc AS |
1147 | - Implemented the TNCCS 1.1 Trusted Network Connect protocol using the |
1148 | libtnc library on the strongSwan client and server side via the tnccs_11 | |
1149 | plugin and optionally connecting to a TNC@FHH-enhanced FreeRADIUS AAA server. | |
1150 | Depending on the resulting TNC Recommendation, strongSwan clients are granted | |
1151 | access to a network behind a strongSwan gateway (allow), are put into a | |
ac544be2 | 1152 | remediation zone (isolate) or are blocked (none), respectively. Any number |
8a1353fc AS |
1153 | of Integrity Measurement Collector/Verifier pairs can be attached |
1154 | via the tnc-imc and tnc-imv charon plugins. | |
1155 | ||
b3cabd1f TB |
1156 | - The IKEv1 daemon pluto now uses the same kernel interfaces as the IKEv2 |
1157 | daemon charon. As a result of this, pluto now supports xfrm marks which | |
1158 | were introduced in charon with 4.4.1. | |
1159 | ||
1160 | - Applets for Maemo 5 (Nokia) allow to easily configure and control IKEv2 | |
1161 | based VPN connections with EAP authentication on supported devices. | |
1162 | ||
18a4f865 MW |
1163 | - The RADIUS plugin eap-radius now supports multiple RADIUS servers for |
1164 | redundant setups. Servers are selected by a defined priority, server load and | |
1165 | availability. | |
1166 | ||
1167 | - The simple led plugin controls hardware LEDs through the Linux LED subsystem. | |
1168 | It currently shows activity of the IKE daemon and is a good example how to | |
1169 | implement a simple event listener. | |
1170 | ||
b3cabd1f TB |
1171 | - Improved MOBIKE behavior in several corner cases, for instance, if the |
1172 | initial responder moves to a different address. | |
1173 | ||
1174 | - Fixed left-/rightnexthop option, which was broken since 4.4.0. | |
1175 | ||
3f84e2d6 AS |
1176 | - Fixed a bug not releasing a virtual IP address to a pool if the XAUTH |
1177 | identity was different from the IKE identity. | |
1178 | ||
f6032361 AS |
1179 | - Fixed the alignment of ModeConfig messages on 4-byte boundaries in the |
1180 | case where the attributes are not a multiple of 4 bytes (e.g. Cisco's | |
1181 | UNITY_BANNER). | |
1182 | ||
1183 | - Fixed the interoperability of the socket_raw and socket_default | |
1184 | charon plugins. | |
1185 | ||
3f84e2d6 AS |
1186 | - Added man page for strongswan.conf |
1187 | ||
a782b52f | 1188 | |
03b5e4d8 AS |
1189 | strongswan-4.4.1 |
1190 | ---------------- | |
1191 | ||
ec40c02a | 1192 | - Support of xfrm marks in IPsec SAs and IPsec policies introduced |
b22bb9f2 AS |
1193 | with the Linux 2.6.34 kernel. For details see the example scenarios |
1194 | ikev2/nat-two-rw-mark, ikev2/rw-nat-mark-in-out and ikev2/net2net-psk-dscp. | |
ec40c02a | 1195 | |
b22bb9f2 | 1196 | - The PLUTO_MARK_IN and PLUTO_ESP_ENC environment variables can be used |
b59340a2 AS |
1197 | in a user-specific updown script to set marks on inbound ESP or |
1198 | ESP_IN_UDP packets. | |
e87b78c6 | 1199 | |
3561cc4b AS |
1200 | - The openssl plugin now supports X.509 certificate and CRL functions. |
1201 | ||
e9448cfc | 1202 | - OCSP/CRL checking in IKEv2 has been moved to the revocation plugin, enabled |
b59340a2 | 1203 | by default. Plase update manual load directives in strongswan.conf. |
e9448cfc MW |
1204 | |
1205 | - RFC3779 ipAddrBlock constraint checking has been moved to the addrblock | |
1206 | plugin, disabled by default. Enable it and update manual load directives | |
1207 | in strongswan.conf, if required. | |
1208 | ||
7f3a9468 MW |
1209 | - The pki utility supports CRL generation using the --signcrl command. |
1210 | ||
1211 | - The ipsec pki --self, --issue and --req commands now support output in | |
1212 | PEM format using the --outform pem option. | |
1213 | ||
03b5e4d8 AS |
1214 | - The major refactoring of the IKEv1 Mode Config functionality now allows |
1215 | the transport and handling of any Mode Config attribute. | |
1216 | ||
e87b78c6 | 1217 | - The RADIUS proxy plugin eap-radius now supports multiple servers. Configured |
b59340a2 AS |
1218 | servers are chosen randomly, with the option to prefer a specific server. |
1219 | Non-responding servers are degraded by the selection process. | |
e87b78c6 | 1220 | |
c5c6f9b6 AS |
1221 | - The ipsec pool tool manages arbitrary configuration attributes stored |
1222 | in an SQL database. ipsec pool --help gives the details. | |
1223 | ||
fe2434cf MW |
1224 | - The new eap-simaka-sql plugin acts as a backend for EAP-SIM and EAP-AKA, |
1225 | reading triplets/quintuplets from an SQL database. | |
1226 | ||
c8bd06c7 MW |
1227 | - The High Availability plugin now supports a HA enabled in-memory address |
1228 | pool and Node reintegration without IKE_SA rekeying. The latter allows | |
1229 | clients without IKE_SA rekeying support to keep connected during | |
1230 | reintegration. Additionally, many other issues have been fixed in the ha | |
1231 | plugin. | |
1c1f132a | 1232 | |
c5c921bf MW |
1233 | - Fixed a potential remote code execution vulnerability resulting from |
1234 | the misuse of snprintf(). The vulnerability is exploitable by | |
1235 | unauthenticated users. | |
1236 | ||
03b5e4d8 | 1237 | |
00c60592 MW |
1238 | strongswan-4.4.0 |
1239 | ---------------- | |
1240 | ||
d101a61f MW |
1241 | - The IKEv2 High Availability plugin has been integrated. It provides |
1242 | load sharing and failover capabilities in a cluster of currently two nodes, | |
1243 | based on an extend ClusterIP kernel module. More information is available at | |
1244 | http://wiki.strongswan.org/projects/strongswan/wiki/HighAvailability. | |
9235edc2 | 1245 | The development of the High Availability functionality was sponsored by |
d101a61f MW |
1246 | secunet Security Networks AG. |
1247 | ||
dd8cb2b0 AS |
1248 | - Added IKEv1 and IKEv2 configuration support for the AES-GMAC |
1249 | authentication-only ESP cipher. Our aes_gmac kernel patch or a Linux | |
1250 | 2.6.34 kernel is required to make AES-GMAC available via the XFRM | |
1251 | kernel interface. | |
1252 | ||
4590260b MW |
1253 | - Added support for Diffie-Hellman groups 22, 23 and 24 to the gmp, gcrypt |
1254 | and openssl plugins, usable by both pluto and charon. The new proposal | |
1255 | keywords are modp1024s160, modp2048s224 and modp2048s256. Thanks to Joy Latten | |
1256 | from IBM for his contribution. | |
1257 | ||
9235edc2 AS |
1258 | - The IKEv1 pluto daemon supports RAM-based virtual IP pools using |
1259 | the rightsourceip directive with a subnet from which addresses | |
1260 | are allocated. | |
1261 | ||
d6457833 AS |
1262 | - The ipsec pki --gen and --pub commands now allow the output of |
1263 | private and public keys in PEM format using the --outform pem | |
1264 | command line option. | |
1265 | ||
2d097a0b MW |
1266 | - The new DHCP plugin queries virtual IP addresses for clients from a DHCP |
1267 | server using broadcasts, or a defined server using the | |
1268 | charon.plugins.dhcp.server strongswan.conf option. DNS/WINS server information | |
1269 | is additionally served to clients if the DHCP server provides such | |
1270 | information. The plugin is used in ipsec.conf configurations having | |
1271 | rightsourceip set to %dhcp. | |
1272 | ||
6d6994c6 MW |
1273 | - A new plugin called farp fakes ARP responses for virtual IP addresses |
1274 | handed out to clients from the IKEv2 daemon charon. The plugin lets a | |
89bf11d2 | 1275 | road-warrior act as a client on the local LAN if it uses a virtual IP |
6d6994c6 MW |
1276 | from the responders subnet, e.g. acquired using the DHCP plugin. |
1277 | ||
00c60592 MW |
1278 | - The existing IKEv2 socket implementations have been migrated to the |
1279 | socket-default and the socket-raw plugins. The new socket-dynamic plugin | |
1280 | binds sockets dynamically to ports configured via the left-/rightikeport | |
1281 | ipsec.conf connection parameters. | |
1282 | ||
3e6b50ed MW |
1283 | - The android charon plugin stores received DNS server information as "net.dns" |
1284 | system properties, as used by the Android platform. | |
00c60592 | 1285 | |
d6457833 | 1286 | |
4c68a85a AS |
1287 | strongswan-4.3.6 |
1288 | ---------------- | |
1289 | ||
cdad91de | 1290 | - The IKEv2 daemon supports RFC 3779 IP address block constraints |
e98a4d80 AS |
1291 | carried as a critical X.509v3 extension in the peer certificate. |
1292 | ||
a7155606 AS |
1293 | - The ipsec pool --add|del dns|nbns command manages DNS and NBNS name |
1294 | server entries that are sent via the IKEv1 Mode Config or IKEv2 | |
1295 | Configuration Payload to remote clients. | |
1296 | ||
f721e0fb AS |
1297 | - The Camellia cipher can be used as an IKEv1 encryption algorithm. |
1298 | ||
4c68a85a AS |
1299 | - The IKEv1 and IKEV2 daemons now check certificate path length constraints. |
1300 | ||
909c0c3d MW |
1301 | - The new ipsec.conf conn option "inactivity" closes a CHILD_SA if no traffic |
1302 | was sent or received within the given interval. To close the complete IKE_SA | |
1303 | if its only CHILD_SA was inactive, set the global strongswan.conf option | |
aa9eeb5d MW |
1304 | "charon.inactivity_close_ike" to yes. |
1305 | ||
44e41c4c AS |
1306 | - More detailed IKEv2 EAP payload information in debug output |
1307 | ||
2b2c69e9 | 1308 | - IKEv2 EAP-SIM and EAP-AKA share joint libsimaka library |
44e41c4c | 1309 | |
52fd0ef9 MW |
1310 | - Added required userland changes for proper SHA256 and SHA384/512 in ESP that |
1311 | will be introduced with Linux 2.6.33. The "sha256"/"sha2_256" keyword now | |
1312 | configures the kernel with 128 bit truncation, not the non-standard 96 | |
1313 | bit truncation used by previous releases. To use the old 96 bit truncation | |
1314 | scheme, the new "sha256_96" proposal keyword has been introduced. | |
4c68a85a | 1315 | |
2b2c69e9 MW |
1316 | - Fixed IPComp in tunnel mode, stripping out the duplicated outer header. This |
1317 | change makes IPcomp tunnel mode connections incompatible with previous | |
1318 | releases; disable compression on such tunnels. | |
1319 | ||
6ec949e0 MW |
1320 | - Fixed BEET mode connections on recent kernels by installing SAs with |
1321 | appropriate traffic selectors, based on a patch by Michael Rossberg. | |
1322 | ||
cdad91de MW |
1323 | - Using extensions (such as BEET mode) and crypto algorithms (such as twofish, |
1324 | serpent, sha256_96) allocated in the private use space now require that we | |
1325 | know its meaning, i.e. we are talking to strongSwan. Use the new | |
1326 | "charon.send_vendor_id" option in strongswan.conf to let the remote peer know | |
1327 | this is the case. | |
1328 | ||
aca9f9ab MW |
1329 | - Experimental support for draft-eronen-ipsec-ikev2-eap-auth, where the |
1330 | responder omits public key authentication in favor of a mutual authentication | |
1331 | method. To enable EAP-only authentication, set rightauth=eap on the responder | |
1332 | to rely only on the MSK constructed AUTH payload. This not-yet standardized | |
1333 | extension requires the strongSwan vendor ID introduced above. | |
1334 | ||
0a975307 AS |
1335 | - The IKEv1 daemon ignores the Juniper SRX notification type 40001, thus |
1336 | allowing interoperability. | |
1337 | ||
1338 | ||
b6b90b68 MW |
1339 | strongswan-4.3.5 |
1340 | ---------------- | |
1341 | ||
628f023d AS |
1342 | - The IKEv1 pluto daemon can now use SQL-based address pools to deal out |
1343 | virtual IP addresses as a Mode Config server. The pool capability has been | |
1344 | migrated from charon's sql plugin to a new attr-sql plugin which is loaded | |
b42bfc79 | 1345 | by libstrongswan and which can be used by both daemons either with a SQLite |
628f023d AS |
1346 | or MySQL database and the corresponding plugin. |
1347 | ||
b42bfc79 MW |
1348 | - Plugin names have been streamlined: EAP plugins now have a dash after eap |
1349 | (e.g. eap-sim), as it is used with the --enable-eap-sim ./configure option. | |
1350 | Plugin configuration sections in strongswan.conf now use the same name as the | |
1351 | plugin itself (i.e. with a dash). Make sure to update "load" directives and | |
1352 | the affected plugin sections in existing strongswan.conf files. | |
1353 | ||
d245f5cf AS |
1354 | - The private/public key parsing and encoding has been split up into |
1355 | separate pkcs1, pgp, pem and dnskey plugins. The public key implementation | |
1356 | plugins gmp, gcrypt and openssl can all make use of them. | |
b6b90b68 | 1357 | |
55b045ab MW |
1358 | - The EAP-AKA plugin can use different backends for USIM/quintuplet |
1359 | calculations, very similar to the EAP-SIM plugin. The existing 3GPP2 software | |
1360 | implementation has been migrated to a separate plugin. | |
1361 | ||
d245f5cf | 1362 | - The IKEv2 daemon charon gained basic PGP support. It can use locally installed |
b6b90b68 MW |
1363 | peer certificates and can issue signatures based on RSA private keys. |
1364 | ||
1365 | - The new 'ipsec pki' tool provides a set of commands to maintain a public | |
1366 | key infrastructure. It currently supports operations to create RSA and ECDSA | |
1367 | private/public keys, calculate fingerprints and issue or verify certificates. | |
1368 | ||
1369 | - Charon uses a monotonic time source for statistics and job queueing, behaving | |
1370 | correctly if the system time changes (e.g. when using NTP). | |
1371 | ||
1372 | - In addition to time based rekeying, charon supports IPsec SA lifetimes based | |
1373 | on processed volume or number of packets. They new ipsec.conf paramaters | |
1374 | 'lifetime' (an alias to 'keylife'), 'lifebytes' and 'lifepackets' handle | |
1375 | SA timeouts, while the parameters 'margintime' (an alias to rekeymargin), | |
1376 | 'marginbytes' and 'marginpackets' trigger the rekeying before a SA expires. | |
1377 | The existing parameter 'rekeyfuzz' affects all margins. | |
1378 | ||
85af7a89 MW |
1379 | - If no CA/Gateway certificate is specified in the NetworkManager plugin, |
1380 | charon uses a set of trusted root certificates preinstalled by distributions. | |
1381 | The directory containing CA certificates can be specified using the | |
1382 | --with-nm-ca-dir=path configure option. | |
1383 | ||
b80fa9ca | 1384 | - Fixed the encoding of the Email relative distinguished name in left|rightid |
509f70c1 | 1385 | statements. |
b80fa9ca | 1386 | |
509f70c1 AS |
1387 | - Fixed the broken parsing of PKCS#7 wrapped certificates by the pluto daemon. |
1388 | ||
1389 | - Fixed smartcard-based authentication in the pluto daemon which was broken by | |
1390 | the ECDSA support introduced with the 4.3.2 release. | |
1391 | ||
cea4bd8f AS |
1392 | - A patch contributed by Heiko Hund fixes mixed IPv6 in IPv4 and vice versa |
1393 | tunnels established with the IKEv1 pluto daemon. | |
1394 | ||
509f70c1 AS |
1395 | - The pluto daemon now uses the libstrongswan x509 plugin for certificates and |
1396 | CRls and the struct id type was replaced by identification_t used by charon | |
1397 | and the libstrongswan library. | |
18060241 | 1398 | |
85af7a89 | 1399 | |
430dd08a AS |
1400 | strongswan-4.3.4 |
1401 | ---------------- | |
1402 | ||
1403 | - IKEv2 charon daemon ported to FreeBSD and Mac OS X. Installation details can | |
1404 | be found on wiki.strongswan.org. | |
1405 | ||
1406 | - ipsec statusall shows the number of bytes transmitted and received over | |
1407 | ESP connections configured by the IKEv2 charon daemon. | |
1408 | ||
1409 | - The IKEv2 charon daemon supports include files in ipsec.secrets. | |
1410 | ||
1411 | ||
1c7f456a AS |
1412 | strongswan-4.3.3 |
1413 | ---------------- | |
1414 | ||
aa74d705 AS |
1415 | - The configuration option --enable-integrity-test plus the strongswan.conf |
1416 | option libstrongswan.integrity_test = yes activate integrity tests | |
1417 | of the IKE daemons charon and pluto, libstrongswan and all loaded | |
1418 | plugins. Thus dynamic library misconfigurations and non-malicious file | |
1419 | manipulations can be reliably detected. | |
1420 | ||
1c7f456a AS |
1421 | - The new default setting libstrongswan.ecp_x_coordinate_only=yes allows |
1422 | IKEv1 interoperability with MS Windows using the ECP DH groups 19 and 20. | |
1423 | ||
1424 | - The IKEv1 pluto daemon now supports the AES-CCM and AES-GCM ESP | |
1425 | authenticated encryption algorithms. | |
1426 | ||
aa74d705 AS |
1427 | - The IKEv1 pluto daemon now supports V4 OpenPGP keys. |
1428 | ||
1429 | - The RDN parser vulnerability discovered by Orange Labs research team | |
1430 | was not completely fixed in version 4.3.2. Some more modifications | |
1431 | had to be applied to the asn1_length() function to make it robust. | |
1432 | ||
1c7f456a | 1433 | |
80c0710c MW |
1434 | strongswan-4.3.2 |
1435 | ---------------- | |
1436 | ||
1437 | - The new gcrypt plugin provides symmetric cipher, hasher, RNG, Diffie-Hellman | |
1438 | and RSA crypto primitives using the LGPL licensed GNU gcrypt library. | |
1439 | ||
1440 | - libstrongswan features an integrated crypto selftest framework for registered | |
1441 | algorithms. The test-vector plugin provides a first set of test vectors and | |
1442 | allows pluto and charon to rely on tested crypto algorithms. | |
1443 | ||
b32af120 AS |
1444 | - pluto can now use all libstrongswan plugins with the exception of x509 and xcbc. |
1445 | Thanks to the openssl plugin, the ECP Diffie-Hellman groups 19, 20, 21, 25, and | |
1446 | 26 as well as ECDSA-256, ECDSA-384, and ECDSA-521 authentication can be used | |
1447 | with IKEv1. | |
126f2130 AS |
1448 | |
1449 | - Applying their fuzzing tool, the Orange Labs vulnerability research team found | |
1450 | another two DoS vulnerabilities, one in the rather old ASN.1 parser of Relative | |
1451 | Distinguished Names (RDNs) and a second one in the conversion of ASN.1 UTCTIME | |
1452 | and GENERALIZEDTIME strings to a time_t value. | |
b6b90b68 | 1453 | |
b32af120 | 1454 | |
3bf7c249 MW |
1455 | strongswan-4.3.1 |
1456 | ---------------- | |
1457 | ||
1458 | - The nm plugin now passes DNS/NBNS server information to NetworkManager, | |
09dbca9f | 1459 | allowing a gateway administrator to set DNS/NBNS configuration on clients |
3bf7c249 MW |
1460 | dynamically. |
1461 | ||
09dbca9f MW |
1462 | - The nm plugin also accepts CA certificates for gateway authentication. If |
1463 | a CA certificate is configured, strongSwan uses the entered gateway address | |
1464 | as its idenitity, requiring the gateways certificate to contain the same as | |
1465 | subjectAltName. This allows a gateway administrator to deploy the same | |
1466 | certificates to Windows 7 and NetworkManager clients. | |
047b2e42 | 1467 | |
050cc582 AS |
1468 | - The command ipsec purgeike deletes IKEv2 SAs that don't have a CHILD SA. |
1469 | The command ipsec down <conn>{n} deletes CHILD SA instance n of connection | |
1470 | <conn> whereas ipsec down <conn>{*} deletes all CHILD SA instances. | |
1471 | The command ipsec down <conn>[n] deletes IKE SA instance n of connection | |
1472 | <conn> plus dependent CHILD SAs whereas ipsec down <conn>[*] deletes all | |
1473 | IKE SA instances of connection <conn>. | |
1474 | ||
09dbca9f | 1475 | - Fixed a regression introduced in 4.3.0 where EAP authentication calculated |
047b2e42 MW |
1476 | the AUTH payload incorrectly. Further, the EAP-MSCHAPv2 MSK key derivation |
1477 | has been updated to be compatible with the Windows 7 Release Candidate. | |
1478 | ||
1479 | - Refactored installation of triggering policies. Routed policies are handled | |
1480 | outside of IKE_SAs to keep them installed in any case. A tunnel gets | |
1481 | established only once, even if initiation is delayed due network outages. | |
1482 | ||
050cc582 AS |
1483 | - Improved the handling of multiple acquire signals triggered by the kernel. |
1484 | ||
1485 | - Fixed two DoS vulnerabilities in the charon daemon that were discovered by | |
1486 | fuzzing techniques: 1) Sending a malformed IKE_SA_INIT request leaved an | |
1487 | incomplete state which caused a null pointer dereference if a subsequent | |
1488 | CREATE_CHILD_SA request was sent. 2) Sending an IKE_AUTH request with either | |
1489 | a missing TSi or TSr payload caused a null pointer derefence because the | |
b6b90b68 | 1490 | checks for TSi and TSr were interchanged. The IKEv2 fuzzer used was |
f3bb1bd0 | 1491 | developed by the Orange Labs vulnerability research team. The tool was |
050cc582 AS |
1492 | initially written by Gabriel Campana and is now maintained by Laurent Butti. |
1493 | ||
047b2e42 MW |
1494 | - Added support for AES counter mode in ESP in IKEv2 using the proposal |
1495 | keywords aes128ctr, aes192ctr and aes256ctr. | |
1496 | ||
d44fd821 | 1497 | - Further progress in refactoring pluto: Use of the curl and ldap plugins |
050cc582 AS |
1498 | for fetching crls and OCSP. Use of the random plugin to get keying material |
1499 | from /dev/random or /dev/urandom. Use of the openssl plugin as an alternative | |
d44fd821 | 1500 | to the aes, des, sha1, sha2, and md5 plugins. The blowfish, twofish, and |
050cc582 | 1501 | serpent encryption plugins are now optional and are not enabled by default. |
d44fd821 AS |

1504 | strongswan-4.3.0 |
1505 | ---------------- | |
1506 | ||
81fc8e5f MW |
1507 | - Support for the IKEv2 Multiple Authentication Exchanges extension (RFC4739). |
1508 | Initiators and responders can use several authentication rounds (e.g. RSA | |
1509 | followed by EAP) to authenticate. The new ipsec.conf leftauth/rightauth and | |
1510 | leftauth2/rightauth2 parameters define own authentication rounds or setup | |
1511 | constraints for the remote peer. See the ipsec.conf man page for more detials. | |
1512 | ||
1513 | - If glibc printf hooks (register_printf_function) are not available, | |
1514 | strongSwan can use the vstr string library to run on non-glibc systems. | |
1515 | ||
558c89e7 AS |
1516 | - The IKEv2 charon daemon can now configure the ESP CAMELLIA-CBC cipher |
1517 | (esp=camellia128|192|256). | |
247e665a | 1518 | |
558c89e7 AS |
1519 | - Refactored the pluto and scepclient code to use basic functions (memory |
1520 | allocation, leak detective, chunk handling, printf_hooks, strongswan.conf | |
1521 | attributes, ASN.1 parser, etc.) from the libstrongswan library. | |
b752f873 | 1522 | |
558c89e7 AS |
1523 | - Up to two DNS and WINS servers to be sent via IKEv1 ModeConfig can be |
1524 | configured in the pluto section of strongswan.conf. | |

1527 | strongswan-4.2.14 |
1528 | ----------------- | |
1529 | ||
22180558 | 1530 | - The new server-side EAP RADIUS plugin (--enable-eap-radius) |
f3bb1bd0 | 1531 | relays EAP messages to and from a RADIUS server. Successfully |
22180558 AS |
1532 | tested with with a freeradius server using EAP-MD5 and EAP-SIM. |
1533 | ||
79b27294 AS |
1534 | - A vulnerability in the Dead Peer Detection (RFC 3706) code was found by |
1535 | Gerd v. Egidy <gerd.von.egidy@intra2net.com> of Intra2net AG affecting | |
1536 | all Openswan and strongSwan releases. A malicious (or expired ISAKMP) | |
1537 | R_U_THERE or R_U_THERE_ACK Dead Peer Detection packet can cause the | |
1538 | pluto IKE daemon to crash and restart. No authentication or encryption | |
1539 | is required to trigger this bug. One spoofed UDP packet can cause the | |
1540 | pluto IKE daemon to restart and be unresponsive for a few seconds while | |
1541 | restarting. This DPD null state vulnerability has been officially | |
1542 | registered as CVE-2009-0790 and is fixed by this release. | |
1543 | ||
22180558 AS |
1544 | - ASN.1 to time_t conversion caused a time wrap-around for |
1545 | dates after Jan 18 03:14:07 UTC 2038 on 32-bit platforms. | |
1546 | As a workaround such dates are set to the maximum representable | |
1547 | time, i.e. Jan 19 03:14:07 UTC 2038. | |
1548 | ||
1549 | - Distinguished Names containing wildcards (*) are not sent in the | |
b6b90b68 | 1550 | IDr payload anymore. |

076e7853 AS |
1553 | strongswan-4.2.13 |
1554 | ----------------- | |
1555 | ||
1556 | - Fixed a use-after-free bug in the DPD timeout section of the | |
1557 | IKEv1 pluto daemon which sporadically caused a segfault. | |
1558 | ||
f3bb1bd0 | 1559 | - Fixed a crash in the IKEv2 charon daemon occurring with |
b6b90b68 | 1560 | mixed RAM-based and SQL-based virtual IP address pools. |
076e7853 | 1561 | |
f15483ef AS |

bfde75ee AS |
1570 | |
1571 | - Support of the EAP-MSCHAPv2 protocol enabled by the option | |
1572 | --enable-eap-mschapv2. Requires the MD4 hash algorithm enabled | |
1573 | either by --enable-md4 or --enable-openssl. | |
1574 | ||
1575 | - Assignment of up to two DNS and up to two WINS servers to peers via | |
b6b90b68 | 1576 | the IKEv2 Configuration Payload (CP). The IPv4 or IPv6 nameserver |
bfde75ee AS |
1577 | addresses are defined in strongswan.conf. |
1578 | ||
1579 | - The strongSwan applet for the Gnome NetworkManager is now built and | |
1580 | distributed as a separate tarball under the name NetworkManager-strongswan. | |
1581 | ||
b6b90b68 | 1582 | |
0519ca90 AS |
1583 | strongswan-4.2.11 |
1584 | ----------------- | |
1585 | ||
ae1ae574 AS |
1586 | - Fixed ESP NULL encryption broken by the refactoring of keymat.c. |
1587 | Also introduced proper initialization and disposal of keying material. | |
1588 | ||
1589 | - Fixed the missing listing of connection definitions in ipsec statusall | |
1590 | broken by an unfortunate local variable overload. | |
0519ca90 AS |
1591 | |
1592 | ||
4856241c MW |
1593 | strongswan-4.2.10 |
1594 | ----------------- | |
1595 | ||
1596 | - Several performance improvements to handle thousands of tunnels with almost | |
1597 | linear upscaling. All relevant data structures have been replaced by faster | |
1598 | counterparts with better lookup times. | |
1599 | ||
1600 | - Better parallelization to run charon on multiple cores. Due to improved | |
1601 | ressource locking and other optimizations the daemon can take full | |
1602 | advantage of 16 or even more cores. | |
1603 | ||
1604 | - The load-tester plugin can use a NULL Diffie-Hellman group and simulate | |
1605 | unique identities and certificates by signing peer certificates using a CA | |
1606 | on the fly. | |
1607 | ||
1608 | - The redesigned stroke in-memory IP pool handles leases. The "ipsec leases" | |
1609 | command queries assigned leases. | |
1610 | ||
1611 | - Added support for smartcards in charon by using the ENGINE API provided by | |
1612 | OpenSSL, based on patches by Michael Roßberg. | |
1613 | ||
1614 | - The Padlock plugin supports the hardware RNG found on VIA CPUs to provide a | |
1615 | reliable source of randomness. | |
1616 | ||
73937bd8 MW |
1617 | strongswan-4.2.9 |
1618 | ---------------- | |
1619 | ||
509e07c5 AS |
1620 | - Flexible configuration of logging subsystem allowing to log to multiple |
1621 | syslog facilities or to files using fine-grained log levels for each target. | |
73937bd8 MW |
1622 | |
1623 | - Load testing plugin to do stress testing of the IKEv2 daemon against self | |
1624 | or another host. Found and fixed issues during tests in the multi-threaded | |
1625 | use of the OpenSSL plugin. | |
1626 | ||
1627 | - Added profiling code to synchronization primitives to find bottlenecks if | |
7bdc931e | 1628 | running on multiple cores. Found and fixed an issue where parts of the |
73937bd8 MW |
1629 | Diffie-Hellman calculation acquired an exclusive lock. This greatly improves |
1630 | parallelization to multiple cores. | |
1631 | ||
509e07c5 AS |
1632 | - updown script invocation has been separated into a plugin of its own to |
1633 | further slim down the daemon core. | |
73937bd8 | 1634 | |
509e07c5 | 1635 | - Separated IKE_SA/CHILD_SA key derivation process into a closed system, |
7bdc931e | 1636 | allowing future implementations to use a secured environment in e.g. kernel |
73937bd8 MW |
1637 | memory or hardware. |
1638 | ||
509e07c5 AS |
1639 | - The kernel interface of charon has been modularized. XFRM NETLINK (default) |
1640 | and PFKEY (--enable-kernel-pfkey) interface plugins for the native IPsec | |
1641 | stack of the Linux 2.6 kernel as well as a PFKEY interface for the KLIPS | |
1642 | IPsec stack (--enable-kernel-klips) are provided. | |
1643 | ||
1644 | - Basic Mobile IPv6 support has been introduced, securing Binding Update | |
1645 | messages as well as tunneled traffic between Mobile Node and Home Agent. | |
1646 | The installpolicy=no option allows peaceful cooperation with a dominant | |
1647 | mip6d daemon and the new type=transport_proxy implements the special MIPv6 | |
1648 | IPsec transport proxy mode where the IKEv2 daemon uses the Care-of-Address | |
f3bb1bd0 | 1649 | but the IPsec SA is set up for the Home Address. |
7bdc931e | 1650 | |
4dc0dce8 AS |
1651 | - Implemented migration of Mobile IPv6 connections using the KMADDRESS |
1652 | field contained in XFRM_MSG_MIGRATE messages sent by the mip6d daemon | |
1653 | via the Linux 2.6.28 (or appropriately patched) kernel. | |
1654 | ||

e39b271b AS |
1656 | strongswan-4.2.8 |
1657 | ---------------- | |
1658 | ||
5dadb16e | 1659 | - IKEv2 charon daemon supports authentication based on raw public keys |
e39b271b AS |
1660 | stored in the SQL database backend. The ipsec listpubkeys command |
1661 | lists the available raw public keys via the stroke interface. | |
1662 | ||
4f0241e6 MW |
1663 | - Several MOBIKE improvements: Detect changes in NAT mappings in DPD exchanges, |
1664 | handle events if kernel detects NAT mapping changes in UDP-encapsulated | |
1665 | ESP packets (requires kernel patch), reuse old addesses in MOBIKE updates as | |
1666 | long as possible and other fixes. | |
1667 | ||
5dadb16e AS |
1668 | - Fixed a bug in addr_in_subnet() which caused insertion of wrong source |
1669 | routes for destination subnets having netwmasks not being a multiple of 8 bits. | |
1670 | Thanks go to Wolfgang Steudel, TU Ilmenau for reporting this bug. | |
1671 | ||

1673 | strongswan-4.2.7 |
1674 | ---------------- | |
1675 | ||
b37cda82 AS |
1676 | - Fixed a Denial-of-Service vulnerability where an IKE_SA_INIT message with |
1677 | a KE payload containing zeroes only can cause a crash of the IKEv2 charon | |
1678 | daemon due to a NULL pointer returned by the mpz_export() function of the | |
1679 | GNU Multiprecision Library (GMP). Thanks go to Mu Dynamics Research Labs | |
b6b90b68 | 1680 | for making us aware of this problem. |
b37cda82 | 1681 | |
b6b90b68 | 1682 | - The new agent plugin provides a private key implementation on top of an |
e376d75f MW |
1683 | ssh-agent. |
1684 | ||
1685 | - The NetworkManager plugin has been extended to support certificate client | |
b1f47854 | 1686 | authentication using RSA keys loaded from a file or using ssh-agent. |
e376d75f MW |
1687 | |
1688 | - Daemon capability dropping has been ported to libcap and must be enabled | |
1689 | explicitly --with-capabilities=libcap. Future version will support the | |
1690 | newer libcap2 library. | |
1691 | ||
b37cda82 AS |
1692 | - ipsec listalgs lists the IKEv2 cryptografic algorithms registered with the |
1693 | charon keying daemon. | |

1696 | strongswan-4.2.6 |
1697 | ---------------- | |
1698 | ||
609166f4 MW |
1699 | - A NetworkManager plugin allows GUI-based configuration of road-warrior |
1700 | clients in a simple way. It features X509 based gateway authentication | |
1701 | and EAP client authentication, tunnel setup/teardown and storing passwords | |
1702 | in the Gnome Keyring. | |
1703 | ||
1704 | - A new EAP-GTC plugin implements draft-sheffer-ikev2-gtc-00.txt and allows | |
1705 | username/password authentication against any PAM service on the gateway. | |
b6b90b68 | 1706 | The new EAP method interacts nicely with the NetworkManager plugin and allows |
609166f4 MW |
1707 | client authentication against e.g. LDAP. |
1708 | ||
1709 | - Improved support for the EAP-Identity method. The new ipsec.conf eap_identity | |
1710 | parameter defines an additional identity to pass to the server in EAP | |
1711 | authentication. | |
1712 | ||
9f9d6ece AS |
1713 | - The "ipsec statusall" command now lists CA restrictions, EAP |
1714 | authentication types and EAP identities. | |
1715 | ||
1716 | - Fixed two multithreading deadlocks occurring when starting up | |
1717 | several hundred tunnels concurrently. | |
1718 | ||
1719 | - Fixed the --enable-integrity-test configure option which | |
1720 | computes a SHA-1 checksum over the libstrongswan library. | |
1721 | ||
1722 | ||
174216c7 AS |
1723 | strongswan-4.2.5 |
1724 | ---------------- | |
1725 | ||
b6b90b68 | 1726 | - Consistent logging of IKE and CHILD SAs at the audit (AUD) level. |
8124e491 AS |
1727 | |
1728 | - Improved the performance of the SQL-based virtual IP address pool | |
1729 | by introducing an additional addresses table. The leases table | |
1730 | storing only history information has become optional and can be | |
1731 | disabled by setting charon.plugins.sql.lease_history = no in | |
1732 | strongswan.conf. | |
1733 | ||
eb0cc338 | 1734 | - The XFRM_STATE_AF_UNSPEC flag added to xfrm.h allows IPv4-over-IPv6 |
de5f70e7 | 1735 | and IPv6-over-IPv4 tunnels with the 2.6.26 and later Linux kernels. |
eb0cc338 | 1736 | |
174216c7 AS |
1737 | - management of different virtual IP pools for different |
1738 | network interfaces have become possible. | |
1739 | ||
b6b90b68 | 1740 | - fixed a bug which prevented the assignment of more than 256 |
174216c7 AS |
1741 | virtual IP addresses from a pool managed by an sql database. |
1742 | ||
8124e491 AS |
1743 | - fixed a bug which did not delete own IPCOMP SAs in the kernel. |
1744 | ||
b6b90b68 | 1745 | |
179dd12c AS |
1746 | strongswan-4.2.4 |
1747 | ---------------- | |
1748 | ||
9de95037 AS |
1749 | - Added statistics functions to ipsec pool --status and ipsec pool --leases |
1750 | and input validation checks to various ipsec pool commands. | |
179dd12c | 1751 | |
73a8eed3 | 1752 | - ipsec statusall now lists all loaded charon plugins and displays |
9de95037 | 1753 | the negotiated IKEv2 cipher suite proposals. |
73a8eed3 AS |
1754 | |
1755 | - The openssl plugin supports the elliptic curve Diffie-Hellman groups | |
1756 | 19, 20, 21, 25, and 26. | |
1757 | ||
1758 | - The openssl plugin supports ECDSA authentication using elliptic curve | |
1759 | X.509 certificates. | |
1760 | ||
1761 | - Fixed a bug in stroke which caused multiple charon threads to close | |
1762 | the file descriptors during packet transfers over the stroke socket. | |
b6b90b68 | 1763 | |
e0bb4dbb AS |
1764 | - ESP sequence numbers are now migrated in IPsec SA updates handled by |
1765 | MOBIKE. Works only with Linux kernels >= 2.6.17. | |

179dd12c | 1767 | |
83d9e870 AS |
1768 | strongswan-4.2.3 |
1769 | ---------------- | |
1770 | ||
b6b90b68 | 1771 | - Fixed the strongswan.conf path configuration problem that occurred when |
83d9e870 AS |
1772 | --sysconfig was not set explicitly in ./configure. |
1773 | ||
1774 | - Fixed a number of minor bugs that where discovered during the 4th | |
1775 | IKEv2 interoperability workshop in San Antonio, TX. | |

1777 | ||
7f491111 MW |
1778 | strongswan-4.2.2 |
1779 | ---------------- | |
1780 | ||
a57cd446 AS |
1781 | - Plugins for libstrongswan and charon can optionally be loaded according |
1782 | to a configuration in strongswan.conf. Most components provide a | |
7f491111 | 1783 | "load = " option followed by a space separated list of plugins to load. |
a57cd446 AS |
1784 | This allows e.g. the fallback from a hardware crypto accelerator to |
1785 | to software-based crypto plugins. | |
7f491111 MW |
1786 | |
1787 | - Charons SQL plugin has been extended by a virtual IP address pool. | |
a57cd446 AS |
1788 | Configurations with a rightsourceip=%poolname setting query a SQLite or |
1789 | MySQL database for leases. The "ipsec pool" command helps in administrating | |
1790 | the pool database. See ipsec pool --help for the available options | |
1791 | ||
1792 | - The Authenticated Encryption Algorithms AES-CCM-8/12/16 and AES-GCM-8/12/16 | |
b6b90b68 | 1793 | for ESP are now supported starting with the Linux 2.6.25 kernel. The |
a57cd446 AS |
1794 | syntax is e.g. esp=aes128ccm12 or esp=aes256gcm16. |
1795 | ||
7f491111 | 1796 | |
5c5d67d6 AS |
1797 | strongswan-4.2.1 |
1798 | ---------------- | |
1799 | ||
c306dfb1 | 1800 | - Support for "Hash and URL" encoded certificate payloads has been implemented |
b1f8fc0c TB |
1801 | in the IKEv2 daemon charon. Using the "certuribase" option of a CA section |
1802 | allows to assign a base URL to all certificates issued by the specified CA. | |
1803 | The final URL is then built by concatenating that base and the hex encoded | |
1804 | SHA1 hash of the DER encoded certificate. Note that this feature is disabled | |
1805 | by default and must be enabled using the option "charon.hash_and_url". | |
5c5d67d6 | 1806 | |
58caabf7 MW |
1807 | - The IKEv2 daemon charon now supports the "uniqueids" option to close multiple |
1808 | IKE_SAs with the same peer. The option value "keep" prefers existing | |
1809 | connection setups over new ones, where the value "replace" replaces existing | |
1810 | connections. | |
b6b90b68 | 1811 | |
f3bb1bd0 | 1812 | - The crypto factory in libstrongswan additionally supports random number |
58caabf7 | 1813 | generators, plugins may provide other sources of randomness. The default |
c306dfb1 | 1814 | plugin reads raw random data from /dev/(u)random. |
58caabf7 | 1815 | |
b6b90b68 | 1816 | - Extended the credential framework by a caching option to allow plugins |
58caabf7 | 1817 | persistent caching of fetched credentials. The "cachecrl" option has been |
c306dfb1 | 1818 | re-implemented. |
58caabf7 MW |
1819 | |
1820 | - The new trustchain verification introduced in 4.2.0 has been parallelized. | |
1821 | Threads fetching CRL or OCSP information no longer block other threads. | |
5c5d67d6 | 1822 | |
58caabf7 MW |
1823 | - A new IKEv2 configuration attribute framework has been introduced allowing |
1824 | plugins to provide virtual IP addresses, and in the future, other | |
1825 | configuration attribute services (e.g. DNS/WINS servers). | |
5c5d67d6 | 1826 | |
466abb49 | 1827 | - The stroke plugin has been extended to provide virtual IP addresses from |
58caabf7 MW |
1828 | a pool defined in ipsec.conf. The "rightsourceip" parameter now accepts |
1829 | address pools in CIDR notation (e.g. 10.1.1.0/24). The parameter also accepts | |
1830 | the value "%poolname", where "poolname" identifies a pool provided by a | |
466abb49 | 1831 | separate plugin. |
58caabf7 | 1832 | |
c306dfb1 | 1833 | - Fixed compilation on uClibc and a couple of other minor bugs. |
58caabf7 | 1834 | |
c306dfb1 | 1835 | - Set DPD defaults in ipsec starter to dpd_delay=30s and dpd_timeout=150s. |
466abb49 AS |
1836 | |
1837 | - The IKEv1 pluto daemon now supports the ESP encryption algorithm CAMELLIA | |
c306dfb1 | 1838 | with key lengths of 128, 192, and 256 bits, as well as the authentication |
466abb49 AS |
1839 | algorithm AES_XCBC_MAC. Configuration example: esp=camellia192-aesxcbc. |

1842 | strongswan-4.2.0 |
1843 | ---------------- | |
1844 | ||
16f5dacd MW |
1845 | - libstrongswan has been modularized to attach crypto algorithms, |
1846 | credential implementations (keys, certificates) and fetchers dynamically | |
1847 | through plugins. Existing code has been ported to plugins: | |
1848 | - RSA/Diffie-Hellman implementation using the GNU Multi Precision library | |
1849 | - X509 certificate system supporting CRLs, OCSP and attribute certificates | |
1850 | - Multiple plugins providing crypto algorithms in software | |
1851 | - CURL and OpenLDAP fetcher | |
a11ea97d | 1852 | |
16f5dacd MW |
1853 | - libstrongswan gained a relational database API which uses pluggable database |
1854 | providers. Plugins for MySQL and SQLite are available. | |
1855 | ||
1856 | - The IKEv2 keying daemon charon is more extensible. Generic plugins may provide | |
1857 | connection configuration, credentials and EAP methods or control the daemon. | |
1858 | Existing code has been ported to plugins: | |
1859 | - EAP-AKA, EAP-SIM, EAP-MD5 and EAP-Identity | |
1860 | - stroke configuration, credential and control (compatible to pluto) | |
1861 | - XML bases management protocol to control and query the daemon | |
1862 | The following new plugins are available: | |
1863 | - An experimental SQL configuration, credential and logging plugin on | |
1864 | top of either MySQL or SQLite | |
1865 | - A unit testing plugin to run tests at daemon startup | |
1866 | ||
1867 | - The authentication and credential framework in charon has been heavily | |
1868 | refactored to support modular credential providers, proper | |
1869 | CERTREQ/CERT payload exchanges and extensible authorization rules. | |
1870 | ||
b6b90b68 | 1871 | - The framework of strongSwan Manager has envolved to the web application |
16f5dacd MW |
1872 | framework libfast (FastCGI Application Server w/ Templates) and is usable |
1873 | by other applications. | |

1877 | ----------------- | |
fb6d76cd | 1878 | |
a561f74d AS |
1879 | - IKE rekeying in NAT situations did not inherit the NAT conditions |
1880 | to the rekeyed IKE_SA so that the UDP encapsulation was lost with | |
1881 | the next CHILD_SA rekeying. | |
1882 | ||
1883 | - Wrong type definition of the next_payload variable in id_payload.c | |
b6b90b68 | 1884 | caused an INVALID_SYNTAX error on PowerPC platforms. |
fb6d76cd | 1885 | |
e6b50b3f AS |
1886 | - Implemented IKEv2 EAP-SIM server and client test modules that use |
1887 | triplets stored in a file. For details on the configuration see | |
1888 | the scenario 'ikev2/rw-eap-sim-rsa'. | |
1889 | ||

83e0d841 AS |
1891 | strongswan-4.1.10 |
1892 | ----------------- | |
1893 | ||
1894 | - Fixed error in the ordering of the certinfo_t records in the ocsp cache that | |
b6b90b68 | 1895 | caused multiple entries of the same serial number to be created. |
83e0d841 | 1896 | |
fdc7c943 MW |
1897 | - Implementation of a simple EAP-MD5 module which provides CHAP |
1898 | authentication. This may be interesting in conjunction with certificate | |
1899 | based server authentication, as weak passwords can't be brute forced | |
1900 | (in contradiction to traditional IKEv2 PSK). | |
1901 | ||
1902 | - A complete software based implementation of EAP-AKA, using algorithms | |
1903 | specified in 3GPP2 (S.S0055). This implementation does not use an USIM, | |
1904 | but reads the secrets from ipsec.secrets. Make sure to read eap_aka.h | |
1905 | before using it. | |
1906 | ||
1907 | - Support for vendor specific EAP methods using Expanded EAP types. The | |
b6b90b68 | 1908 | interface to EAP modules has been slightly changed, so make sure to |
fdc7c943 | 1909 | check the changes if you're already rolling your own modules. |

1912 | strongswan-4.1.9 |
1913 | ---------------- | |
1914 | ||
800b3356 AS |
1915 | - The default _updown script now dynamically inserts and removes ip6tables |
1916 | firewall rules if leftfirewall=yes is set in IPv6 connections. New IPv6 | |
1917 | net-net and roadwarrior (PSK/RSA) scenarios for both IKEv1 and IKEV2 were | |
1918 | added. | |
5076770c | 1919 | |
6f274c2a MW |
1920 | - Implemented RFC4478 repeated authentication to force EAP/Virtual-IP clients |
1921 | to reestablish an IKE_SA within a given timeframe. | |
1922 | ||
1923 | - strongSwan Manager supports configuration listing, initiation and termination | |
1924 | of IKE and CHILD_SAs. | |
1925 | ||
1926 | - Fixes and improvements to multithreading code. | |
1927 | ||
8b678ad4 | 1928 | - IKEv2 plugins have been renamed to libcharon-* to avoid naming conflicts. |
b6b90b68 | 1929 | Make sure to remove the old plugins in $libexecdir/ipsec, otherwise they get |
8b678ad4 | 1930 | loaded twice. |

1933 | strongswan-4.1.8 |
1934 | ---------------- | |
1935 | ||
5076770c | 1936 | - Removed recursive pthread mutexes since uClibc doesn't support them. |
b82e8231 AS |
1937 | |

a4a3632c AS |
1939 | strongswan-4.1.7 |
1940 | ---------------- | |
1941 | ||
1942 | - In NAT traversal situations and multiple queued Quick Modes, | |
1943 | those pending connections inserted by auto=start after the | |
1944 | port floating from 500 to 4500 were erronously deleted. | |
1945 | ||
6e193274 | 1946 | - Added a "forceencaps" connection parameter to enforce UDP encapsulation |
078b6008 | 1947 | to surmount restrictive firewalls. NAT detection payloads are faked to |
6e193274 MW |
1948 | simulate a NAT situation and trick the other peer into NAT mode (IKEv2 only). |
1949 | ||
1950 | - Preview of strongSwan Manager, a web based configuration and monitoring | |
1951 | application. It uses a new XML control interface to query the IKEv2 daemon | |
64d24679 | 1952 | (see http://wiki.strongswan.org/wiki/Manager). |
6e193274 MW |
1953 | |
1954 | - Experimental SQLite configuration backend which will provide the configuration | |
1955 | interface for strongSwan Manager in future releases. | |
1956 | ||
1957 | - Further improvements to MOBIKE support. | |
1958 | ||
a4a3632c | 1959 | |
3dcf9dbd AS |
1960 | strongswan-4.1.6 |
1961 | ---------------- | |
1962 | ||
3eac4dfd AS |
1963 | - Since some third party IKEv2 implementations run into |
1964 | problems with strongSwan announcing MOBIKE capability per | |
1965 | default, MOBIKE can be disabled on a per-connection-basis | |
1966 | using the mobike=no option. Whereas mobike=no disables the | |
1967 | sending of the MOBIKE_SUPPORTED notification and the floating | |
1968 | to UDP port 4500 with the IKE_AUTH request even if no NAT | |
1969 | situation has been detected, strongSwan will still support | |
1970 | MOBIKE acting as a responder. | |
1971 | ||
1972 | - the default ipsec routing table plus its corresponding priority | |
1973 | used for inserting source routes has been changed from 100 to 220. | |
1974 | It can be configured using the --with-ipsec-routing-table and | |
b6b90b68 MW |
1975 | --with-ipsec-routing-table-prio options. |
1976 | ||
bdc0b55b AS |
1977 | - the --enable-integrity-test configure option tests the |
1978 | integrity of the libstrongswan crypto code during the charon | |
1979 | startup. | |
b6b90b68 | 1980 | |
3eac4dfd AS |
1981 | - the --disable-xauth-vid configure option disables the sending |
1982 | of the XAUTH vendor ID. This can be used as a workaround when | |
1983 | interoperating with some Windows VPN clients that get into | |
1984 | trouble upon reception of an XAUTH VID without eXtended | |
1985 | AUTHentication having been configured. | |
b6b90b68 | 1986 | |
f872f9d1 AS |
1987 | - ipsec stroke now supports the rereadsecrets, rereadaacerts, |
1988 | rereadacerts, and listacerts options. | |
3dcf9dbd AS |
1989 | |
1990 | ||
7ad634a2 AS |
1991 | strongswan-4.1.5 |
1992 | ---------------- | |
1993 | ||
1994 | - If a DNS lookup failure occurs when resolving right=%<FQDN> | |
1995 | or right=<FQDN> combined with rightallowany=yes then the | |
1996 | connection is not updated by ipsec starter thus preventing | |
1997 | the disruption of an active IPsec connection. Only if the DNS | |
1998 | lookup successfully returns with a changed IP address the | |
1999 | corresponding connection definition is updated. | |
2000 | ||
8f5b363c MW |
2001 | - Routes installed by the keying daemons are now in a separate |
2002 | routing table with the ID 100 to avoid conflicts with the main | |
2003 | table. Route lookup for IKEv2 traffic is done in userspace to ignore | |
2004 | routes installed for IPsec, as IKE traffic shouldn't get encapsulated. | |
2005 | ||
7ad634a2 | 2006 | |
e93c68ba AS |
2007 | strongswan-4.1.4 |
2008 | ---------------- | |
2009 | ||
2010 | - The pluto IKEv1 daemon now exhibits the same behaviour as its | |
2011 | IKEv2 companion charon by inserting an explicit route via the | |
2012 | _updown script only if a sourceip exists. This is admissible | |
2013 | since routing through the IPsec tunnel is handled automatically | |
b7af55ac AS |
2014 | by NETKEY's IPsec policies. As a consequence the left|rightnexthop |
2015 | parameter is not required any more. | |
078ce348 AS |
2016 | |
2017 | - The new IKEv1 parameter right|leftallowany parameters helps to handle | |
2018 | the case where both peers possess dynamic IP addresses that are | |
2019 | usually resolved using DynDNS or a similar service. The configuration | |
2020 | ||
2021 | right=peer.foo.bar | |
2022 | rightallowany=yes | |
2023 | ||
2024 | can be used by the initiator to start up a connection to a peer | |
2025 | by resolving peer.foo.bar into the currently allocated IP address. | |
2026 | Thanks to the rightallowany flag the connection behaves later on | |
2027 | as | |
2028 | ||
2029 | right=%any | |
2030 | ||
2031 | so that the peer can rekey the connection as an initiator when his | |
1fbdab85 AS |
2032 | IP address changes. An alternative notation is |
2033 | ||
2034 | right=%peer.foo.bar | |
2035 | ||
2036 | which will implicitly set rightallowany=yes. | |
2037 | ||
2038 | - ipsec starter now fails more gracefully in the presence of parsing | |
2039 | errors. Flawed ca and conn section are discarded and pluto is started | |
2040 | if non-fatal errors only were encountered. If right=%peer.foo.bar | |
2041 | cannot be resolved by DNS then right=%any will be used so that passive | |
2042 | connections as a responder are still possible. | |
078ce348 | 2043 | |
a0a0bdd7 AS |
2044 | - The new pkcs11initargs parameter that can be placed in the |
2045 | setup config section of /etc/ipsec.conf allows the definition | |
2046 | of an argument string that is used with the PKCS#11 C_Initialize() | |
2047 | function. This non-standard feature is required by the NSS softoken | |
2048 | library. This patch was contributed by Robert Varga. | |
b6b90b68 | 2049 | |
a0a0bdd7 AS |
2050 | - Fixed a bug in ipsec starter introduced by strongswan-2.8.5 |
2051 | which caused a segmentation fault in the presence of unknown | |
2052 | or misspelt keywords in ipsec.conf. This bug fix was contributed | |
2053 | by Robert Varga. | |
2054 | ||
e3606f2b MW |
2055 | - Partial support for MOBIKE in IKEv2. The initiator acts on interface/ |
2056 | address configuration changes and updates IKE and IPsec SAs dynamically. | |
e93c68ba | 2057 | |
06651827 | 2058 | |
a3354a69 AS |
2059 | strongswan-4.1.3 |
2060 | ---------------- | |
2061 | ||
b6b90b68 | 2062 | - IKEv2 peer configuration selection now can be based on a given |
35d4809c AS |
2063 | certification authority using the rightca= statement. |
2064 | ||
2065 | - IKEv2 authentication based on RSA signatures now can handle multiple | |
41e16cf4 AS |
2066 | certificates issued for a given peer ID. This allows a smooth transition |
2067 | in the case of a peer certificate renewal. | |
a3354a69 | 2068 | |
998ca0ea MW |
2069 | - IKEv2: Support for requesting a specific virtual IP using leftsourceip on the |
2070 | client and returning requested virtual IPs using rightsourceip=%config | |
2071 | on the server. If the server does not support configuration payloads, the | |
2072 | client enforces its leftsourceip parameter. | |
2073 | ||
2074 | - The ./configure options --with-uid/--with-gid allow pluto and charon | |
2075 | to drop their privileges to a minimum and change to an other UID/GID. This | |
2076 | improves the systems security, as a possible intruder may only get the | |
2077 | CAP_NET_ADMIN capability. | |
2078 | ||
b6b90b68 | 2079 | - Further modularization of charon: Pluggable control interface and |
998ca0ea MW |
2080 | configuration backend modules provide extensibility. The control interface |
2081 | for stroke is included, and further interfaces using DBUS (NetworkManager) | |
2082 | or XML are on the way. A backend for storing configurations in the daemon | |
b6b90b68 | 2083 | is provided and more advanced backends (using e.g. a database) are trivial |
998ca0ea | 2084 | to implement. |
a3354a69 | 2085 | |
f3bb1bd0 | 2086 | - Fixed a compilation failure in libfreeswan occurring with Linux kernel |
41e16cf4 AS |
2087 | headers > 2.6.17. |
2088 | ||
2089 | ||
8ea7b96f AS |
2090 | strongswan-4.1.2 |
2091 | ---------------- | |
2092 | ||
e23d98a7 | 2093 | - Support for an additional Diffie-Hellman exchange when creating/rekeying |
37fb0355 MW |
2094 | a CHILD_SA in IKEv2 (PFS). PFS is enabled when the proposal contains a |
2095 | DH group (e.g. "esp=aes128-sha1-modp1536"). Further, DH group negotiation | |
2096 | is implemented properly for rekeying. | |
2097 | ||
2098 | - Support for the AES-XCBC-96 MAC algorithm for IPsec SAs when using IKEv2 | |
2099 | (requires linux >= 2.6.20). It is enabled using e.g. "esp=aes256-aesxcbc". | |
2100 | ||
d931f465 MW |
2101 | - Working IPv4-in-IPv6 and IPv6-in-IPv4 tunnels for linux >= 2.6.21. |
2102 | ||
37fb0355 MW |
2103 | - Added support for EAP modules which do not establish an MSK. |
2104 | ||
dfbe2a0f | 2105 | - Removed the dependencies from the /usr/include/linux/ headers by |
9f78f957 | 2106 | including xfrm.h, ipsec.h, and pfkeyv2.h in the distribution. |
b6b90b68 | 2107 | |
9f78f957 AS |
2108 | - crlNumber is now listed by ipsec listcrls |
2109 | ||
8ea7b96f AS |
2110 | - The xauth_modules.verify_secret() function now passes the |
2111 | connection name. | |
2112 | ||
e23d98a7 | 2113 | |
ed284399 MW |
2114 | strongswan-4.1.1 |
2115 | ---------------- | |
2116 | ||
2117 | - Server side cookie support. If to may IKE_SAs are in CONNECTING state, | |
2118 | cookies are enabled and protect against DoS attacks with faked source | |
2119 | addresses. Number of IKE_SAs in CONNECTING state is also limited per | |
2120 | peer address to avoid resource exhaustion. IKE_SA_INIT messages are | |
2121 | compared to properly detect retransmissions and incoming retransmits are | |
2122 | detected even if the IKE_SA is blocked (e.g. doing OCSP fetches). | |
2123 | ||
db88e37d AS |
2124 | - The IKEv2 daemon charon now supports dynamic http- and ldap-based CRL |
2125 | fetching enabled by crlcheckinterval > 0 and caching fetched CRLs | |
2126 | enabled by cachecrls=yes. | |
2127 | ||
3b4f7d92 AS |
2128 | - Added the configuration options --enable-nat-transport which enables |
2129 | the potentially insecure NAT traversal for IPsec transport mode and | |
2130 | --disable-vendor-id which disables the sending of the strongSwan | |
2131 | vendor ID. | |
2132 | ||
2133 | - Fixed a long-standing bug in the pluto IKEv1 daemon which caused | |
2134 | a segmentation fault if a malformed payload was detected in the | |
2135 | IKE MR2 message and pluto tried to send an encrypted notification | |
2136 | message. | |
2137 | ||
46b9ff68 AS |
2138 | - Added the NATT_IETF_02_N Vendor ID in order to support IKEv1 connections |
2139 | with Windows 2003 Server which uses a wrong VID hash. | |
2140 | ||
3b4f7d92 | 2141 | |
34bbd0c3 | 2142 | strongswan-4.1.0 |
cd3958f8 AS |
2143 | ---------------- |
2144 | ||
2145 | - Support of SHA2_384 hash function for protecting IKEv1 | |
2146 | negotiations and support of SHA2 signatures in X.509 certificates. | |
2147 | ||
2148 | - Fixed a serious bug in the computation of the SHA2-512 HMAC | |
2149 | function. Introduced automatic self-test of all IKEv1 hash | |
2150 | and hmac functions during pluto startup. Failure of a self-test | |
2151 | currently issues a warning only but does not exit pluto [yet]. | |
2152 | ||
9b45443d MW |
2153 | - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2. |
2154 | ||
c5d0fbb6 | 2155 | - Full support of CA information sections. ipsec listcainfos |
b6b90b68 | 2156 | now shows all collected crlDistributionPoints and OCSP |
c5d0fbb6 AS |
2157 | accessLocations. |
2158 | ||
69ed04bf AS |
2159 | - Support of the Online Certificate Status Protocol (OCSP) for IKEv2. |
2160 | This feature requires the HTTP fetching capabilities of the libcurl | |
2161 | library which must be enabled by setting the --enable-http configure | |
2162 | option. | |
2163 | ||
9b45443d MW |
2164 | - Refactored core of the IKEv2 message processing code, allowing better |
2165 | code reuse and separation. | |
2166 | ||
2167 | - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration | |
2168 | payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted | |
2169 | by the requestor and installed in a resolv.conf file. | |
2170 | ||
2171 | - The IKEv2 daemon charon installs a route for each IPsec policy to use | |
2172 | the correct source address even if an application does not explicitly | |
2173 | specify it. | |
2174 | ||
2175 | - Integrated the EAP framework into charon which loads pluggable EAP library | |
2176 | modules. The ipsec.conf parameter authby=eap initiates EAP authentication | |
2177 | on the client side, while the "eap" parameter on the server side defines | |
2178 | the EAP method to use for client authentication. | |
2179 | A generic client side EAP-Identity module and an EAP-SIM authentication | |
2180 | module using a third party card reader implementation are included. | |
2181 | ||
2182 | - Added client side support for cookies. | |
2183 | ||
2184 | - Integrated the fixes done at the IKEv2 interoperability bakeoff, including | |
2185 | strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor | |
2186 | fixes to enhance interoperability with other implementations. | |

2189 | strongswan-4.0.7 |
2190 | ---------------- | |
2191 | ||
6fdf5f44 AS |
2192 | - strongSwan now interoperates with the NCP Secure Entry Client, |
2193 | the Shrew Soft VPN Client, and the Cisco VPN client, doing both | |
2194 | XAUTH and Mode Config. | |
1c266d7d AS |
2195 | |
2196 | - UNITY attributes are now recognized and UNITY_BANNER is set | |

2b4405a3 MW |
2200 | strongswan-4.0.6 |
2201 | ---------------- | |
2202 | ||
e38a15d4 AS |
2203 | - IKEv1: Support for extended authentication (XAUTH) in combination |
2204 | with ISAKMP Main Mode RSA or PSK authentication. Both client and | |
2205 | server side were implemented. Handling of user credentials can | |
2206 | be done by a run-time loadable XAUTH module. By default user | |
b6b90b68 MW |
2207 | credentials are stored in ipsec.secrets. |
2208 | ||
2b4405a3 MW |
2209 | - IKEv2: Support for reauthentication when rekeying |
2210 | ||
5903179b | 2211 | - IKEv2: Support for transport mode |
af87afed | 2212 | |
5903179b | 2213 | - fixed a lot of bugs related to byte order |
2b4405a3 | 2214 | |
5903179b | 2215 | - various other bugfixes |

0cd645d2 AS |
2218 | strongswan-4.0.5 |
2219 | ---------------- | |
2220 | ||
2221 | - IKEv1: Implementation of ModeConfig push mode via the new connection | |
2222 | keyword modeconfig=push allows interoperability with Cisco VPN gateways. | |
2223 | ||
2224 | - IKEv1: The command ipsec statusall now shows "DPD active" for all | |
2225 | ISAKMP SAs that are under active Dead Peer Detection control. | |
2226 | ||
2227 | - IKEv2: Charon's logging and debugging framework has been completely rewritten. | |
2228 | Instead of logger, special printf() functions are used to directly | |
2229 | print objects like hosts (%H) identifications (%D), certificates (%Q), | |
2230 | etc. The number of debugging levels have been reduced to: | |
03bf883d | 2231 | |
0cd645d2 | 2232 | 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private) |
03bf883d | 2233 | |
0cd645d2 AS |
2234 | The debugging levels can either be specified statically in ipsec.conf as |
2235 | ||
2236 | config setup | |
03bf883d | 2237 | charondebug="lib 1, cfg 3, net 2" |
0cd645d2 | 2238 | |
03bf883d | 2239 | or changed at runtime via stroke as |
0cd645d2 | 2240 | |
03bf883d | 2241 | ipsec stroke loglevel cfg 2 |
0cd645d2 AS |

48dc3934 MW |
2244 | strongswan-4.0.4 |
2245 | ---------------- | |
2246 | ||
2247 | - Implemented full support for IPv6-in-IPv6 tunnels. | |
2248 | ||
2249 | - Added configuration options for dead peer detection in IKEv2. dpd_action | |
2250 | types "clear", "hold" and "restart" are supported. The dpd_timeout | |
2251 | value is not used, as the normal retransmission policy applies to | |
2252 | detect dead peers. The dpd_delay parameter enables sending of empty | |
2253 | informational message to detect dead peers in case of inactivity. | |
2254 | ||
2255 | - Added support for preshared keys in IKEv2. PSK keys configured in | |
2256 | ipsec.secrets are loaded. The authby parameter specifies the authentication | |
2257 | method to authentificate ourself, the other peer may use PSK or RSA. | |
2258 | ||
2259 | - Changed retransmission policy to respect the keyingtries parameter. | |
2260 | ||
112ad7c3 AS |
2261 | - Added private key decryption. PEM keys encrypted with AES-128/192/256 |
2262 | or 3DES are supported. | |
48dc3934 MW |
2263 | |
2264 | - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to | |
2265 | encrypt IKE traffic. | |
2266 | ||
2267 | - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates | |
2268 | signed with such a hash algorithm. | |
2269 | ||
2270 | - Added initial support for updown scripts. The actions up-host/client and | |
2271 | down-host/client are executed. The leftfirewall=yes parameter | |
2272 | uses the default updown script to insert dynamic firewall rules, a custom | |
2273 | updown script may be specified with the leftupdown parameter. | |
2274 | ||
2275 | ||
a1310b6b MW |
2276 | strongswan-4.0.3 |
2277 | ---------------- | |
2278 | ||
2279 | - Added support for the auto=route ipsec.conf parameter and the | |
b6b90b68 MW |
2280 | ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and |
2281 | CHILD_SAs dynamically on demand when traffic is detected by the | |
a1310b6b MW |
2282 | kernel. |
2283 | ||
2284 | - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter. | |
2285 | As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only | |
2286 | new keys are generated using perfect forward secrecy. An optional flag | |
2287 | which enforces reauthentication will be implemented later. | |
2288 | ||
b425d998 AS |
2289 | - "sha" and "sha1" are now treated as synonyms in the ike= and esp= |
2290 | algorithm configuration statements. | |
2291 | ||
2292 | ||
bf4df11f AS |
2293 | strongswan-4.0.2 |
2294 | ---------------- | |
2295 | ||
623d3dcf AS |
2296 | - Full X.509 certificate trust chain verification has been implemented. |
2297 | End entity certificates can be exchanged via CERT payloads. The current | |
2298 | default is leftsendcert=always, since CERTREQ payloads are not supported | |
2299 | yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls. | |
efa40c11 | 2300 | |
b6b90b68 | 2301 | - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2 |
efa40c11 | 2302 | would offer more possibilities for traffic selection, but the Linux kernel |
b6b90b68 | 2303 | currently does not support it. That's why we stick with these simple |
efa40c11 MW |
2304 | ipsec.conf rules for now. |
2305 | ||
623d3dcf AS |
2306 | - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no |
2307 | IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear, | |
2308 | dpddelay=60s). | |
2309 | ||
efa40c11 MW |
2310 | - Initial NAT traversal support in IKEv2. Charon includes NAT detection |
2311 | notify payloads to detect NAT routers between the peers. It switches | |
2312 | to port 4500, uses UDP encapsulated ESP packets, handles peer address | |
2313 | changes gracefully and sends keep alive message periodically. | |
2314 | ||
b6b90b68 MW |
2315 | - Reimplemented IKE_SA state machine for charon, which allows simultaneous |
2316 | rekeying, more shared code, cleaner design, proper retransmission | |
efa40c11 MW |
2317 | and a more extensible code base. |
2318 | ||
cfd8b27f AS |
2319 | - The mixed PSK/RSA roadwarrior detection capability introduced by the |
2320 | strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal | |
2321 | payloads by the responder right before any defined IKE Main Mode state had | |
2322 | been established. Although any form of bad proposal syntax was being correctly | |
2323 | detected by the payload parser, the subsequent error handler didn't check | |
2324 | the state pointer before logging current state information, causing an | |
2325 | immediate crash of the pluto keying daemon due to a NULL pointer. | |
2326 | ||
bf4df11f | 2327 | |
7e81e975 MW |
2328 | strongswan-4.0.1 |
2329 | ---------------- | |
2330 | ||
b6b90b68 | 2331 | - Added algorithm selection to charon: New default algorithms for |
c15c3d4b MW |
2332 | ike=aes128-sha-modp2048, as both daemons support it. The default |
2333 | for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles | |
2334 | the ike/esp parameter the same way as pluto. As this syntax does | |
b6b90b68 | 2335 | not allow specification of a pseudo random function, the same |
c15c3d4b MW |
2336 | algorithm as for integrity is used (currently sha/md5). Supported |
2337 | algorithms for IKE: | |
2338 | Encryption: aes128, aes192, aes256 | |
2339 | Integrity/PRF: md5, sha (using hmac) | |
2340 | DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192 | |
2341 | and for ESP: | |
b6b90b68 | 2342 | Encryption: aes128, aes192, aes256, 3des, blowfish128, |
c15c3d4b MW |
2343 | blowfish192, blowfish256 |
2344 | Integrity: md5, sha1 | |
2345 | More IKE encryption algorithms will come after porting libcrypto into | |
b6b90b68 | 2346 | libstrongswan. |
f2c2d395 | 2347 | |
c15c3d4b MW |
2348 | - initial support for rekeying CHILD_SAs using IKEv2. Currently no |
2349 | perfect forward secrecy is used. The rekeying parameters rekey, | |
22ff6f57 | 2350 | rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported |
c15c3d4b MW |
2351 | when using IKEv2. WARNING: charon currently is unable to handle |
2352 | simultaneous rekeying. To avoid such a situation, use a large | |
2353 | rekeyfuzz, or even better, set rekey=no on one peer. | |
22ff6f57 | 2354 | |
7e81e975 MW |
2355 | - support for host2host, net2net, host2net (roadwarrior) tunnels |
2356 | using predefined RSA certificates (see uml scenarios for | |
2357 | configuration examples). | |
2358 | ||
f2c2d395 MW |
2359 | - new build environment featuring autotools. Features such |
2360 | as HTTP, LDAP and smartcard support may be enabled using | |
b6b90b68 | 2361 | the ./configure script. Changing install directories |
f2c2d395 MW |
2362 | is possible, too. See ./configure --help for more details. |
2363 | ||
22ff6f57 MW |
2364 | - better integration of charon with ipsec starter, which allows |
2365 | (almost) transparent operation with both daemons. charon | |
2366 | handles ipsec commands up, down, status, statusall, listall, | |
2367 | listcerts and allows proper load, reload and delete of connections | |
2368 | via ipsec starter. | |
2369 | ||
b425d998 | 2370 | |
9820c0e2 MW |
2371 | strongswan-4.0.0 |
2372 | ---------------- | |
2373 | ||
2374 | - initial support of the IKEv2 protocol. Connections in | |
b6b90b68 | 2375 | ipsec.conf designated by keyexchange=ikev2 are negotiated |
9820c0e2 MW |
2376 | by the new IKEv2 charon keying daemon whereas those marked |
2377 | by keyexchange=ikev1 or the default keyexchange=ike are | |
2378 | handled thy the IKEv1 pluto keying daemon. Currently only | |
2379 | a limited subset of functions are available with IKEv2 | |
2380 | (Default AES encryption, authentication based on locally | |
2381 | imported X.509 certificates, unencrypted private RSA keys | |
2382 | in PKCS#1 file format, limited functionality of the ipsec | |
2383 | status command). | |
2384 | ||
2385 | ||
997358a6 MW |
2386 | strongswan-2.7.0 |
2387 | ---------------- | |
2388 | ||
2389 | - the dynamic iptables rules from the _updown_x509 template | |
2390 | for KLIPS and the _updown_policy template for NETKEY have | |
2391 | been merged into the default _updown script. The existing | |
2392 | left|rightfirewall keyword causes the automatic insertion | |
2393 | and deletion of ACCEPT rules for tunneled traffic upon | |
2394 | the successful setup and teardown of an IPsec SA, respectively. | |
2395 | left|rightfirwall can be used with KLIPS under any Linux 2.4 | |
2396 | kernel or with NETKEY under a Linux kernel version >= 2.6.16 | |
f3bb1bd0 | 2397 | in conjunction with iptables >= 1.3.5. For NETKEY under a Linux |
997358a6 MW |
2398 | kernel version < 2.6.16 which does not support IPsec policy |
2399 | matching yet, please continue to use a copy of the _updown_espmark | |
2400 | template loaded via the left|rightupdown keyword. | |
2401 | ||
2402 | - a new left|righthostaccess keyword has been introduced which | |
2403 | can be used in conjunction with left|rightfirewall and the | |
2404 | default _updown script. By default leftfirewall=yes inserts | |
2405 | a bi-directional iptables FORWARD rule for a local client network | |
2406 | with a netmask different from 255.255.255.255 (single host). | |
2407 | This does not allow to access the VPN gateway host via its | |
2408 | internal network interface which is part of the client subnet | |
2409 | because an iptables INPUT and OUTPUT rule would be required. | |
2410 | lefthostaccess=yes will cause this additional ACCEPT rules to | |
b6b90b68 | 2411 | be inserted. |
997358a6 MW |
2412 | |
2413 | - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal | |
2414 | payload is preparsed in order to find out whether the roadwarrior | |
2415 | requests PSK or RSA so that a matching connection candidate can | |
2416 | be found. | |
2417 | ||
2418 | ||
2419 | strongswan-2.6.4 | |
2420 | ---------------- | |
2421 | ||
2422 | - the new _updown_policy template allows ipsec policy based | |
2423 | iptables firewall rules. Required are iptables version | |
2424 | >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes | |
b6b90b68 | 2425 | the _updown_espmark template, so that no INPUT mangle rules |
997358a6 MW |
2426 | are required any more. |
2427 | ||
2428 | - added support of DPD restart mode | |
2429 | ||
2430 | - ipsec starter now allows the use of wildcards in include | |
2431 | statements as e.g. in "include /etc/my_ipsec/*.conf". | |
2432 | Patch courtesy of Matthias Haas. | |
2433 | ||
2434 | - the Netscape OID 'employeeNumber' is now recognized and can be | |
2435 | used as a Relative Distinguished Name in certificates. | |
2436 | ||
2437 | ||
2438 | strongswan-2.6.3 | |
2439 | ---------------- | |
2440 | ||
b6b90b68 | 2441 | - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec |
997358a6 MW |
2442 | command and not of ipsec setup any more. |
2443 | ||
2444 | - ipsec starter now supports AH authentication in conjunction with | |
2445 | ESP encryption. AH authentication is configured in ipsec.conf | |
2446 | via the auth=ah parameter. | |
b6b90b68 | 2447 | |
997358a6 MW |
2448 | - The command ipsec scencrypt|scdecrypt <args> is now an alias for |
2449 | ipsec whack --scencrypt|scdecrypt <args>. | |
2450 | ||
2451 | - get_sa_info() now determines for the native netkey IPsec stack | |
2452 | the exact time of the last use of an active eroute. This information | |
2453 | is used by the Dead Peer Detection algorithm and is also displayed by | |
2454 | the ipsec status command. | |
b6b90b68 | 2455 | |
997358a6 MW |
2456 | |
2457 | strongswan-2.6.2 | |
2458 | ---------------- | |
2459 | ||
2460 | - running under the native Linux 2.6 IPsec stack, the function | |
2461 | get_sa_info() is called by ipsec auto --status to display the current | |
2462 | number of transmitted bytes per IPsec SA. | |
2463 | ||
2464 | - get_sa_info() is also used by the Dead Peer Detection process to detect | |
2465 | recent ESP activity. If ESP traffic was received from the peer within | |
2466 | the last dpd_delay interval then no R_Y_THERE notification must be sent. | |
2467 | ||
2468 | - strongSwan now supports the Relative Distinguished Name "unstructuredName" | |
2469 | in ID_DER_ASN1_DN identities. The following notations are possible: | |
2470 | ||
2471 | rightid="unstructuredName=John Doe" | |
2472 | rightid="UN=John Doe" | |
2473 | ||
2474 | - fixed a long-standing bug which caused PSK-based roadwarrior connections | |
2475 | to segfault in the function id.c:same_id() called by keys.c:get_secret() | |
2476 | if an FQDN, USER_FQDN, or Key ID was defined, as in the following example. | |
2477 | ||
2478 | conn rw | |
2479 | right=%any | |
2480 | rightid=@foo.bar | |
2481 | authby=secret | |
2482 | ||
2483 | - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall). | |
2484 | ||
2485 | - ipsec starter didn't set host_addr and client.addr ports in whack msg. | |
2486 | ||
2487 | - in order to guarantee backwards-compatibility with the script-based | |
2488 | auto function (e.g. auto --replace), the ipsec starter scripts stores | |
2489 | the defaultroute information in the temporary file /var/run/ipsec.info. | |
2490 | ||
2491 | - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH | |
2492 | Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config | |
2493 | servers. | |
2494 | ||
2495 | - the ipsec starter now also recognizes the parameters authby=never and | |
2496 | type=passthrough|pass|drop|reject. | |
2497 | ||
2498 | ||
2499 | strongswan-2.6.1 | |
2500 | ---------------- | |
2501 | ||
2502 | - ipsec starter now supports the also parameter which allows | |
2503 | a modular structure of the connection definitions. Thus | |
2504 | "ipsec start" is now ready to replace "ipsec setup". | |
2505 | ||
2506 | ||
2507 | strongswan-2.6.0 | |
2508 | ---------------- | |
2509 | ||
2510 | - Mathieu Lafon's popular ipsec starter tool has been added to the | |
2511 | strongSwan distribution. Many thanks go to Stephan Scholz from astaro | |
2512 | for his integration work. ipsec starter is a C program which is going | |
2513 | to replace the various shell and awk starter scripts (setup, _plutoload, | |
2514 | _plutostart, _realsetup, _startklips, _confread, and auto). Since | |
2515 | ipsec.conf is now parsed only once, the starting of multiple tunnels is | |
2516 | accelerated tremedously. | |
2517 | ||
2518 | - Added support of %defaultroute to the ipsec starter. If the IP address | |
b6b90b68 | 2519 | changes, a HUP signal to the ipsec starter will automatically |
997358a6 MW |
2520 | reload pluto's connections. |
2521 | ||
2522 | - moved most compile time configurations from pluto/Makefile to | |
2523 | Makefile.inc by defining the options USE_LIBCURL, USE_LDAP, | |
2524 | USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE. | |
2525 | ||
2526 | - removed the ipsec verify and ipsec newhostkey commands | |
2527 | ||
2528 | - fixed some 64-bit issues in formatted print statements | |
2529 | ||
2530 | - The scepclient functionality implementing the Simple Certificate | |
2531 | Enrollment Protocol (SCEP) is nearly complete but hasn't been | |
2532 | documented yet. | |
2533 | ||
2534 | ||
2535 | strongswan-2.5.7 | |
2536 | ---------------- | |
2537 | ||
2538 | - CA certicates are now automatically loaded from a smartcard | |
2539 | or USB crypto token and appear in the ipsec auto --listcacerts | |
2540 | listing. | |
2541 | ||
2542 | ||
2543 | strongswan-2.5.6 | |
2544 | ---------------- | |
2545 | ||
2546 | - when using "ipsec whack --scencrypt <data>" with a PKCS#11 | |
2547 | library that does not support the C_Encrypt() Cryptoki | |
2548 | function (e.g. OpenSC), the RSA encryption is done in | |
2549 | software using the public key fetched from the smartcard. | |
2550 | ||
b6b90b68 | 2551 | - The scepclient function now allows to define the |
997358a6 MW |
2552 | validity of a self-signed certificate using the --days, |
2553 | --startdate, and --enddate options. The default validity | |
2554 | has been changed from one year to five years. | |
2555 | ||
2556 | ||
2557 | strongswan-2.5.5 | |
2558 | ---------------- | |
2559 | ||
2560 | - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11 | |
2561 | interface to other applications for RSA encryption and decryption | |
2562 | via the whack interface. Notation: | |
2563 | ||
2564 | ipsec whack --scencrypt <data> | |
2565 | [--inbase 16|hex|64|base64|256|text|ascii] | |
2566 | [--outbase 16|hex|64|base64|256|text|ascii] | |
2567 | [--keyid <keyid>] | |
2568 | ||
2569 | ipsec whack --scdecrypt <data> | |
2570 | [--inbase 16|hex|64|base64|256|text|ascii] | |
2571 | [--outbase 16|hex|64|base64|256|text|ascii] | |
2572 | [--keyid <keyid>] | |
2573 | ||
b6b90b68 | 2574 | The default setting for inbase and outbase is hex. |
997358a6 MW |
2575 | |
2576 | The new proxy interface can be used for securing symmetric | |
2577 | encryption keys required by the cryptoloop or dm-crypt | |
2578 | disk encryption schemes, especially in the case when | |
2579 | pkcs11keepstate=yes causes pluto to lock the pkcs11 slot | |
2580 | permanently. | |
2581 | ||
2582 | - if the file /etc/ipsec.secrets is lacking during the startup of | |
2583 | pluto then the root-readable file /etc/ipsec.d/private/myKey.der | |
2584 | containing a 2048 bit RSA private key and a matching self-signed | |
2585 | certificate stored in the file /etc/ipsec.d/certs/selfCert.der | |
2586 | is automatically generated by calling the function | |
2587 | ||
2588 | ipsec scepclient --out pkcs1 --out cert-self | |
2589 | ||
2590 | scepclient was written by Jan Hutter and Martin Willi, students | |
2591 | at the University of Applied Sciences in Rapperswil, Switzerland. | |
2592 | ||
2593 | ||
2594 | strongswan-2.5.4 | |
2595 | ---------------- | |
2596 | ||
2597 | - the current extension of the PKCS#7 framework introduced | |
2598 | a parsing error in PKCS#7 wrapped X.509 certificates that are | |
2599 | e.g. transmitted by Windows XP when multi-level CAs are used. | |
2600 | the parsing syntax has been fixed. | |
2601 | ||
2602 | - added a patch by Gerald Richter which tolerates multiple occurrences | |
2603 | of the ipsec0 interface when using KLIPS. | |
2604 | ||
2605 | ||
2606 | strongswan-2.5.3 | |
2607 | ---------------- | |
2608 | ||
2609 | - with gawk-3.1.4 the word "default2 has become a protected | |
2610 | keyword for use in switch statements and cannot be used any | |
2611 | more in the strongSwan scripts. This problem has been | |
2612 | solved by renaming "default" to "defaults" and "setdefault" | |
2613 | in the scripts _confread and auto, respectively. | |
2614 | ||
2615 | - introduced the parameter leftsendcert with the values | |
2616 | ||
2617 | always|yes (the default, always send a cert) | |
2618 | ifasked (send the cert only upon a cert request) | |
2619 | never|no (never send a cert, used for raw RSA keys and | |
b6b90b68 | 2620 | self-signed certs) |
997358a6 MW |
2621 | |
2622 | - fixed the initialization of the ESP key length to a default of | |
2623 | 128 bits in the case that the peer does not send a key length | |
2624 | attribute for AES encryption. | |
2625 | ||
2626 | - applied Herbert Xu's uniqueIDs patch | |
2627 | ||
2628 | - applied Herbert Xu's CLOEXEC patches | |
2629 | ||
2630 | ||
2631 | strongswan-2.5.2 | |
2632 | ---------------- | |
2633 | ||
2634 | - CRLs can now be cached also in the case when the issuer's | |
2635 | certificate does not contain a subjectKeyIdentifier field. | |
2636 | In that case the subjectKeyIdentifier is computed by pluto as the | |
2637 | 160 bit SHA-1 hash of the issuer's public key in compliance | |
2638 | with section 4.2.1.2 of RFC 3280. | |
2639 | ||
2640 | - Fixed a bug introduced by strongswan-2.5.1 which eliminated | |
2641 | not only multiple Quick Modes of a given connection but also | |
2642 | multiple connections between two security gateways. | |
2643 | ||
2644 | ||
2645 | strongswan-2.5.1 | |
2646 | ---------------- | |
2647 | ||
2648 | - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute | |
2649 | installed either by setting auto=route in ipsec.conf or by | |
2650 | a connection put into hold, generates an XFRM_AQUIRE event | |
2651 | for each packet that wants to use the not-yet exisiting | |
2652 | tunnel. Up to now each XFRM_AQUIRE event led to an entry in | |
2653 | the Quick Mode queue, causing multiple IPsec SA to be | |
2654 | established in rapid succession. Starting with strongswan-2.5.1 | |
2655 | only a single IPsec SA is established per host-pair connection. | |
2656 | ||
2657 | - Right after loading the PKCS#11 module, all smartcard slots are | |
2658 | searched for certificates. The result can be viewed using | |
2659 | the command | |
2660 | ||
2661 | ipsec auto --listcards | |
2662 | ||
2663 | The certificate objects found in the slots are numbered | |
2664 | starting with #1, #2, etc. This position number can be used to address | |
2665 | certificates (leftcert=%smartcard) and keys (: PIN %smartcard) | |
2666 | in ipsec.conf and ipsec.secrets, respectively: | |
2667 | ||
2668 | %smartcard (selects object #1) | |
2669 | %smartcard#1 (selects object #1) | |
2670 | %smartcard#3 (selects object #3) | |
2671 | ||
2672 | As an alternative the existing retrieval scheme can be used: | |
2673 | ||
2674 | %smartcard:45 (selects object with id=45) | |
2675 | %smartcard0 (selects first object in slot 0) | |
2676 | %smartcard4:45 (selects object in slot 4 with id=45) | |
2677 | ||
2678 | - Depending on the settings of CKA_SIGN and CKA_DECRYPT | |
2679 | private key flags either C_Sign() or C_Decrypt() is used | |
2680 | to generate a signature. | |
2681 | ||
2682 | - The output buffer length parameter siglen in C_Sign() | |
2683 | is now initialized to the actual size of the output | |
2684 | buffer prior to the function call. This fixes the | |
2685 | CKR_BUFFER_TOO_SMALL error that could occur when using | |
2686 | the OpenSC PKCS#11 module. | |
2687 | ||
2688 | - Changed the initialization of the PKCS#11 CK_MECHANISM in | |
2689 | C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }. | |
2690 | ||
2691 | - Refactored the RSA public/private key code and transferred it | |
2692 | from keys.c to the new pkcs1.c file as a preparatory step | |
2693 | towards the release of the SCEP client. | |
2694 | ||
2695 | ||
2696 | strongswan-2.5.0 | |
2697 | ---------------- | |
2698 | ||
2699 | - The loading of a PKCS#11 smartcard library module during | |
2700 | runtime does not require OpenSC library functions any more | |
2701 | because the corresponding code has been integrated into | |
2702 | smartcard.c. Also the RSAREF pkcs11 header files have been | |
2703 | included in a newly created pluto/rsaref directory so that | |
2704 | no external include path has to be defined any longer. | |
2705 | ||
2706 | - A long-awaited feature has been implemented at last: | |
2707 | The local caching of CRLs fetched via HTTP or LDAP, activated | |
2708 | by the parameter cachecrls=yes in the config setup section | |
2709 | of ipsec.conf. The dynamically fetched CRLs are stored under | |
2710 | a unique file name containing the issuer's subjectKeyID | |
2711 | in /etc/ipsec.d/crls. | |
b6b90b68 | 2712 | |
997358a6 MW |
2713 | - Applied a one-line patch courtesy of Michael Richardson |
2714 | from the Openswan project which fixes the kernel-oops | |
2715 | in KLIPS when an snmp daemon is running on the same box. | |
2716 | ||
2717 | ||
2718 | strongswan-2.4.4 | |
2719 | ---------------- | |
2720 | ||
2721 | - Eliminated null length CRL distribution point strings. | |
2722 | ||
2723 | - Fixed a trust path evaluation bug introduced with 2.4.3 | |
2724 | ||
2725 | ||
2726 | strongswan-2.4.3 | |
2727 | ---------------- | |
2728 | ||
2729 | - Improved the joint OCSP / CRL revocation policy. | |
2730 | OCSP responses have precedence over CRL entries. | |
2731 | ||
2732 | - Introduced support of CRLv2 reason codes. | |
2733 | ||
2734 | - Fixed a bug with key-pad equipped readers which caused | |
2735 | pluto to prompt for the pin via the console when the first | |
2736 | occasion to enter the pin via the key-pad was missed. | |
2737 | ||
2738 | - When pluto is built with LDAP_V3 enabled, the library | |
2739 | liblber required by newer versions of openldap is now | |
2740 | included. | |
2741 | ||
2742 | ||
2743 | strongswan-2.4.2 | |
2744 | ---------------- | |
2745 | ||
2746 | - Added the _updown_espmark template which requires all | |
2747 | incoming ESP traffic to be marked with a default mark | |
2748 | value of 50. | |
b6b90b68 | 2749 | |
997358a6 MW |
2750 | - Introduced the pkcs11keepstate parameter in the config setup |
2751 | section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11 | |
b6b90b68 | 2752 | session and login states are kept as long as possible during |
997358a6 MW |
2753 | the lifetime of pluto. This means that a PIN entry via a key |
2754 | pad has to be done only once. | |
2755 | ||
2756 | - Introduced the pkcs11module parameter in the config setup | |
2757 | section of ipsec.conf which specifies the PKCS#11 module | |
2758 | to be used with smart cards. Example: | |
b6b90b68 | 2759 | |
997358a6 | 2760 | pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo |
b6b90b68 | 2761 | |
997358a6 MW |
2762 | - Added support of smartcard readers equipped with a PIN pad. |
2763 | ||
2764 | - Added patch by Jay Pfeifer which detects when netkey | |
2765 | modules have been statically built into the Linux 2.6 kernel. | |
2766 | ||
2767 | - Added two patches by Herbert Xu. The first uses ip xfrm | |
2768 | instead of setkey to flush the IPsec policy database. The | |
2769 | second sets the optional flag in inbound IPComp SAs only. | |
b6b90b68 | 2770 | |
997358a6 MW |
2771 | - Applied Ulrich Weber's patch which fixes an interoperability |
2772 | problem between native IPsec and KLIPS systems caused by | |
2773 | setting the replay window to 32 instead of 0 for ipcomp. | |
2774 | ||
2775 | ||
2776 | strongswan-2.4.1 | |
2777 | ---------------- | |
2778 | ||
2779 | - Fixed a bug which caused an unwanted Mode Config request | |
2780 | to be initiated in the case where "right" was used to denote | |
2781 | the local side in ipsec.conf and "left" the remote side, | |
2782 | contrary to the recommendation that "right" be remote and | |
2783 | "left" be"local". | |
2784 | ||
2785 | ||
2786 | strongswan-2.4.0a | |
2787 | ----------------- | |
2788 | ||
2789 | - updated Vendor ID to strongSwan-2.4.0 | |
2790 | ||
2791 | - updated copyright statement to include David Buechi and | |
2792 | Michael Meier | |
b6b90b68 MW |
2793 | |
2794 | ||
997358a6 MW |
2795 | strongswan-2.4.0 |
2796 | ---------------- | |
2797 | ||
2798 | - strongSwan now communicates with attached smartcards and | |
2799 | USB crypto tokens via the standardized PKCS #11 interface. | |
2800 | By default the OpenSC library from www.opensc.org is used | |
2801 | but any other PKCS#11 library could be dynamically linked. | |
2802 | strongSwan's PKCS#11 API was implemented by David Buechi | |
2803 | and Michael Meier, both graduates of the Zurich University | |
2804 | of Applied Sciences in Winterthur, Switzerland. | |
2805 | ||
2806 | - When a %trap eroute is triggered by an outgoing IP packet | |
2807 | then the native IPsec stack of the Linux 2.6 kernel [often/ | |
2808 | always?] returns an XFRM_ACQUIRE message with an undefined | |
2809 | protocol family field and the connection setup fails. | |
2810 | As a workaround IPv4 (AF_INET) is now assumed. | |
b6b90b68 MW |
2811 | |
2812 | - the results of the UML test scenarios are now enhanced | |
997358a6 | 2813 | with block diagrams of the virtual network topology used |
b6b90b68 | 2814 | in a particular test. |
997358a6 MW |
2815 | |
2816 | ||
2817 | strongswan-2.3.2 | |
2818 | ---------------- | |
2819 | ||
2820 | - fixed IV used to decrypt informational messages. | |
2821 | This bug was introduced with Mode Config functionality. | |
b6b90b68 | 2822 | |
997358a6 MW |
2823 | - fixed NCP Vendor ID. |
2824 | ||
2825 | - undid one of Ulrich Weber's maximum udp size patches | |
2826 | because it caused a segmentation fault with NAT-ed | |
2827 | Delete SA messages. | |
b6b90b68 | 2828 | |
997358a6 MW |
2829 | - added UML scenarios wildcards and attr-cert which |
2830 | demonstrate the implementation of IPsec policies based | |
2831 | on wildcard parameters contained in Distinguished Names and | |
2832 | on X.509 attribute certificates, respectively. | |
2833 | ||
2834 | ||
2835 | strongswan-2.3.1 | |
2836 | ---------------- | |
2837 | ||
2838 | - Added basic Mode Config functionality | |
2839 | ||
2840 | - Added Mathieu Lafon's patch which upgrades the status of | |
2841 | the NAT-Traversal implementation to RFC 3947. | |
b6b90b68 | 2842 | |
997358a6 MW |
2843 | - The _startklips script now also loads the xfrm4_tunnel |
2844 | module. | |
b6b90b68 | 2845 | |
997358a6 MW |
2846 | - Added Ulrich Weber's netlink replay window size and |
2847 | maximum udp size patches. | |
2848 | ||
2849 | - UML testing now uses the Linux 2.6.10 UML kernel by default. | |
b6b90b68 | 2850 | |
997358a6 MW |
2851 | |
2852 | strongswan-2.3.0 | |
2853 | ---------------- | |
2854 | ||
2855 | - Eric Marchionni and Patrik Rayo, both recent graduates from | |
2856 | the Zuercher Hochschule Winterthur in Switzerland, created a | |
2857 | User-Mode-Linux test setup for strongSwan. For more details | |
2858 | please read the INSTALL and README documents in the testing | |
2859 | subdirectory. | |
2860 | ||
2861 | - Full support of group attributes based on X.509 attribute | |
b6b90b68 | 2862 | certificates. Attribute certificates can be generated |
997358a6 | 2863 | using the openac facility. For more details see |
b6b90b68 | 2864 | |
997358a6 | 2865 | man ipsec_openac. |
b6b90b68 | 2866 | |
997358a6 MW |
2867 | The group attributes can be used in connection definitions |
2868 | in order to give IPsec access to specific user groups. | |
2869 | This is done with the new parameter left|rightgroups as in | |
b6b90b68 | 2870 | |
997358a6 MW |
2871 | rightgroups="Research, Sales" |
2872 | ||
2873 | giving access to users possessing the group attributes | |
2874 | Research or Sales, only. | |
2875 | ||
2876 | - In Quick Mode clients with subnet mask /32 are now | |
b6b90b68 | 2877 | coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should |
997358a6 MW |
2878 | fix rekeying problems with the SafeNet/SoftRemote and NCP |
2879 | Secure Entry Clients. | |
2880 | ||
2881 | - Changed the defaults of the ikelifetime and keylife parameters | |
2882 | to 3h and 1h, respectively. The maximum allowable values are | |
2883 | now both set to 24 h. | |
2884 | ||
2885 | - Suppressed notification wars between two IPsec peers that | |
2886 | could e.g. be triggered by incorrect ISAKMP encryption. | |
2887 | ||
2888 | - Public RSA keys can now have identical IDs if either the | |
2889 | issuing CA or the serial number is different. The serial | |
2890 | number of a certificate is now shown by the command | |
b6b90b68 | 2891 | |
997358a6 MW |
2892 | ipsec auto --listpubkeys |
2893 | ||
2894 | ||
2895 | strongswan-2.2.2 | |
2896 | ---------------- | |
2897 | ||
2898 | - Added Tuomo Soini's sourceip feature which allows a strongSwan | |
2899 | roadwarrior to use a fixed Virtual IP (see README section 2.6) | |
2900 | and reduces the well-known four tunnel case on VPN gateways to | |
2901 | a single tunnel definition (see README section 2.4). | |
2902 | ||
f3bb1bd0 | 2903 | - Fixed a bug occurring with NAT-Traversal enabled when the responder |
997358a6 MW |
2904 | suddenly turns initiator and the initiator cannot find a matching |
2905 | connection because of the floated IKE port 4500. | |
b6b90b68 | 2906 | |
997358a6 MW |
2907 | - Removed misleading ipsec verify command from barf. |
2908 | ||
2909 | - Running under the native IP stack, ipsec --version now shows | |
2910 | the Linux kernel version (courtesy to the Openswan project). | |
2911 | ||
2912 | ||
2913 | strongswan-2.2.1 | |
2914 | ---------------- | |
2915 | ||
2916 | - Introduced the ipsec auto --listalgs monitoring command which lists | |
2917 | all currently registered IKE and ESP algorithms. | |
2918 | ||
f3bb1bd0 | 2919 | - Fixed a bug in the ESP algorithm selection occurring when the strict flag |
997358a6 | 2920 | is set and the first proposed transform does not match. |
b6b90b68 | 2921 | |
997358a6 | 2922 | - Fixed another deadlock in the use of the lock_certs_and_keys() mutex, |
f3bb1bd0 | 2923 | occurring when a smartcard is present. |
997358a6 MW |
2924 | |
2925 | - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event. | |
b6b90b68 | 2926 | |
997358a6 MW |
2927 | - Fixed the printing of the notification names (null) |
2928 | ||
2929 | - Applied another of Herbert Xu's Netlink patches. | |
2930 | ||
2931 | ||
2932 | strongswan-2.2.0 | |
2933 | ---------------- | |
2934 | ||
2935 | - Support of Dead Peer Detection. The connection parameter | |
2936 | ||
2937 | dpdaction=clear|hold | |
b6b90b68 | 2938 | |
997358a6 MW |
2939 | activates DPD for the given connection. |
2940 | ||
2941 | - The default Opportunistic Encryption (OE) policy groups are not | |
2942 | automatically included anymore. Those wishing to activate OE can include | |
2943 | the policy group with the following statement in ipsec.conf: | |
b6b90b68 | 2944 | |
997358a6 | 2945 | include /etc/ipsec.d/examples/oe.conf |
b6b90b68 | 2946 | |
997358a6 MW |
2947 | The default for [right|left]rsasigkey is now set to %cert. |
2948 | ||
2949 | - strongSwan now has a Vendor ID of its own which can be activated | |
2950 | using the compile option VENDORID | |
2951 | ||
2952 | - Applied Herbert Xu's patch which sets the compression algorithm correctly. | |
2953 | ||
2954 | - Applied Herbert Xu's patch fixing an ESPINUDP problem | |
2955 | ||
2956 | - Applied Herbert Xu's patch setting source/destination port numbers. | |
2957 | ||
2958 | - Reapplied one of Herbert Xu's NAT-Traversal patches which got | |
2959 | lost during the migration from SuperFreeS/WAN. | |
b6b90b68 | 2960 | |
997358a6 MW |
2961 | - Fixed a deadlock in the use of the lock_certs_and_keys() mutex. |
2962 | ||
2963 | - Fixed the unsharing of alg parameters when instantiating group | |
2964 | connection. | |
b6b90b68 | 2965 | |
997358a6 MW |
2966 | |
2967 | strongswan-2.1.5 | |
2968 | ---------------- | |
2969 | ||
2970 | - Thomas Walpuski made me aware of a potential DoS attack via | |
2971 | a PKCS#7-wrapped certificate bundle which could overwrite valid CA | |
2972 | certificates in Pluto's authority certificate store. This vulnerability | |
2973 | was fixed by establishing trust in CA candidate certificates up to a | |
2974 | trusted root CA prior to insertion into Pluto's chained list. | |
2975 | ||
2976 | - replaced the --assign option by the -v option in the auto awk script | |
2977 | in order to make it run with mawk under debian/woody. | |
2978 | ||
2979 | ||
2980 | strongswan-2.1.4 | |
2981 | ---------------- | |
2982 | ||
2983 | - Split of the status information between ipsec auto --status (concise) | |
2984 | and ipsec auto --statusall (verbose). Both commands can be used with | |
2985 | an optional connection selector: | |
2986 | ||
2987 | ipsec auto --status[all] <connection_name> | |
2988 | ||
2989 | - Added the description of X.509 related features to the ipsec_auto(8) | |
2990 | man page. | |
2991 | ||
2992 | - Hardened the ASN.1 parser in debug mode, especially the printing | |
2993 | of malformed distinguished names. | |
2994 | ||
2995 | - The size of an RSA public key received in a certificate is now restricted to | |
2996 | ||
2997 | 512 bits <= modulus length <= 8192 bits. | |
2998 | ||
2999 | - Fixed the debug mode enumeration. | |
3000 | ||
3001 | ||
3002 | strongswan-2.1.3 | |
3003 | ---------------- | |
3004 | ||
3005 | - Fixed another PKCS#7 vulnerability which could lead to an | |
3006 | endless loop while following the X.509 trust chain. | |
b6b90b68 | 3007 | |
997358a6 MW |
3008 | |
3009 | strongswan-2.1.2 | |
3010 | ---------------- | |
3011 | ||
3012 | - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski | |
3013 | that accepted end certificates having identical issuer and subject | |
3014 | distinguished names in a multi-tier X.509 trust chain. | |
b6b90b68 | 3015 | |
997358a6 MW |
3016 | |
3017 | strongswan-2.1.1 | |
3018 | ---------------- | |
3019 | ||
3020 | - Removed all remaining references to ipsec_netlink.h in KLIPS. | |
3021 | ||
3022 | ||
3023 | strongswan-2.1.0 | |
3024 | ---------------- | |
3025 | ||
3026 | - The new "ca" section allows to define the following parameters: | |
3027 | ||
3028 | ca kool | |
3029 | cacert=koolCA.pem # cacert of kool CA | |
3030 | ocspuri=http://ocsp.kool.net:8001 # ocsp server | |
3031 | ldapserver=ldap.kool.net # default ldap server | |

3062 | ---------------- | |
3063 | ||
3064 | - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName | |
3065 | certificate extension which contains no generalName item) can cause | |
3066 | a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has | |
3067 | been hardened to make it more robust against malformed ASN.1 objects. | |
3068 | ||
3069 | - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native | |
3070 | Linux 2.6 IPsec stack. | |
