1 | strongswan-5.3.0 |
2 | ---------------- | |
3 | ||
4a00f912 MW |
4 | - Added support for IKEv2 make-before-break reauthentication. By using a global |
5 | CHILD_SA reqid allocation mechanism, charon supports overlapping CHILD_SAs. | |
6 | This allows the use of make-before-break instead of the previously supported | |
7 | break-before-make reauthentication, avoiding connectivity gaps during that | |
8 | procedure. As the new mechanism may fail with peers not supporting it (such | |
9 | as any previous strongSwan release) it must be explicitly enabled using | |
10 | the charon.make_before_break strongswan.conf option. | |
11 | ||
3f1ef3a6 TB |
12 | - Support for "Signature Authentication in IKEv2" (RFC 7427) has been added. |
13 | This allows the use of stronger hash algorithms for public key authentication. | |
14 | By default, signature schemes are chosen based on the strength of the | |
15 | signature key, but specific hash algorithms may be configured in leftauth. | |
16 | ||
17 | - Key types and hash algorithms specified in rightauth are now also checked | |
18 | against IKEv2 signature schemes. If such constraints are used for certificate | |
19 | chain validation in existing configurations, in particular with peers that | |
20 | don't support RFC 7427, it may be necessary to disable this feature with the | |
21 | charon.signature_authentication_constraints setting, because the signature | |
22 | scheme used in classic IKEv2 public key authentication may not be strong | |
23 | enough. | |
24 | ||
1e1e88e6 MW |
25 | - The new connmark plugin allows a host to bind conntrack flows to a specific |
26 | CHILD_SA by applying and restoring the SA mark to conntrack entries. This | |
27 | allows a peer to handle multiple transport mode connections coming over the | |
28 | same NAT device for client-initiated flows. A common use case is to protect | |
29 | L2TP/IPsec, as supported by some systems. | |
30 | ||
dc88d179 MW |
31 | - The forecast plugin can forward broadcast and multicast messages between |
32 | connected clients and a LAN. For CHILD_SA using unique marks, it sets up | |
33 | the required Netfilter rules and uses a multicast/broadcast listener that | |
34 | forwards such messages to all connected clients. This plugin is designed for | |
35 | Windows 7 IKEv2 clients, which announces its services over the tunnel if the | |
36 | negotiated IPsec policy allows it. | |
37 | ||
2185c29b MW |
38 | - For the vici plugin a Python Egg has been added to allow Python applications |
39 | to control or monitor the IKE daemon using the VICI interface, similar to the | |
40 | existing ruby gem. The Python library has been contributed by Björn Schuberg. | |
41 | ||
f05a578b MW |
42 | - EAP server methods now can fulfill public key constraints, such as rightcert |
43 | or rightca. Additionally, public key and signature constraints can be | |
44 | specified for EAP methods in the rightauth keyword. Currently the EAP-TLS and | |
45 | EAP-TTLS methods provide verification details to constraints checking. | |
46 | ||
27bd0fed AS |
47 | - Upgrade of the BLISS post-quantum signature algorithm to the improved BLISS-B |
48 | variant. Can be used in conjunction with the SHA256, SHA384 and SHA512 hash | |
49 | algorithms with SHA512 being the default. | |
50 | ||
e0359350 AS |
51 | - The IF-IMV 1.4 interface now makes the IP address of the TNC access requestor |
52 | as seen by the TNC server available to all IMVs. This information can be | |
53 | forwarded to policy enforcement points (e.g. firewalls or routers). | |
54 | ||

56 | strongswan-5.2.2 |
57 | ---------------- | |
58 | ||
919449a3 TB |
59 | - Fixed a denial-of-service vulnerability triggered by an IKEv2 Key Exchange |
60 | payload that contains the Diffie-Hellman group 1025. This identifier was | |
61 | used internally for DH groups with custom generator and prime. Because | |
62 | these arguments are missing when creating DH objects based on the KE payload | |
63 | an invalid pointer dereference occurred. This allowed an attacker to crash | |
64 | the IKE daemon with a single IKE_SA_INIT message containing such a KE | |
65 | payload. The vulnerability has been registered as CVE-2014-9221. | |
66 | ||
045501d5 MW |
67 | - The left/rightid options in ipsec.conf, or any other identity in strongSwan, |
68 | now accept prefixes to enforce an explicit type, such as email: or fqdn:. | |
69 | Note that no conversion is done for the remaining string, refer to | |
70 | ipsec.conf(5) for details. | |
71 | ||
30a90ccf | 72 | - The post-quantum Bimodal Lattice Signature Scheme (BLISS) can be used as |
32d19652 AS |
73 | an IKEv2 public key authentication method. The pki tool offers full support |
74 | for the generation of BLISS key pairs and certificates. | |
75 | ||
30a90ccf TB |
76 | - Fixed mapping of integrity algorithms negotiated for AH via IKEv1. This could |
77 | cause interoperability issues when connecting to older versions of charon. | |
78 | ||

dcdcae01 MW |
80 | strongswan-5.2.1 |
81 | ---------------- | |
82 | ||
83 | - The new charon-systemd IKE daemon implements an IKE daemon tailored for use | |
84 | with systemd. It avoids the dependency on ipsec starter and uses swanctl | |
85 | as configuration backend, building a simple and lightweight solution. It | |
86 | supports native systemd journal logging. | |
87 | ||
55758bec TB |
88 | - Support for IKEv2 fragmentation as per RFC 7383 has been added. Like IKEv1 |
89 | fragmentation it can be enabled by setting fragmentation=yes in ipsec.conf. | |
90 | ||
e9a93cb7 AS |
91 | - Support of the TCG TNC IF-M Attribute Segmentation specification proposal. |
92 | All attributes can be segmented. Additionally TCG/SWID Tag, TCG/SWID Tag ID | |
93 | and IETF/Installed Packages attributes can be processed incrementally on a | |
94 | per segment basis. | |
95 | ||

96 | - The new ext-auth plugin calls an external script to implement custom IKE_SA |
97 | authorization logic, courtesy of Vyronas Tsingaras. | |
98 | ||
7431ad0d MW |
99 | - For the vici plugin a ruby gem has been added to allow ruby applications |
100 | to control or monitor the IKE daemon. The vici documentation has been updated | |
101 | to include a description of the available operations and some simple examples | |
102 | using both the libvici C interface and the ruby gem. | |

105 | strongswan-5.2.0 |
106 | ---------------- | |
107 | ||
4c5e52f5 MW |
108 | - strongSwan has been ported to the Windows platform. Using a MinGW toolchain, |
109 | many parts of the strongSwan codebase run natively on Windows 7 / 2008 R2 | |
110 | and newer releases. charon-svc implements a Windows IKE service based on | |
111 | libcharon, the kernel-iph and kernel-wfp plugins act as networking and IPsec | |
112 | backend on the Windows platform. socket-win provides a native IKE socket | |
113 | implementation, while winhttp fetches CRL and OCSP information using the | |
114 | WinHTTP API. | |
115 | ||
4787523c MW |
116 | - The new vici plugin provides a Versatile IKE Configuration Interface for |
117 | charon. Using the stable IPC interface, external applications can configure, | |
118 | control and monitor the IKE daemon. Instead of scripting the ipsec tool | |
119 | and generating ipsec.conf, third party applications can use the new interface | |
120 | for more control and better reliability. | |
121 | ||
b30c09ea MW |
122 | - Built upon the libvici client library, swanctl implements the first user of |
123 | the VICI interface. Together with a swanctl.conf configuration file, | |
124 | connections can be defined, loaded and managed. swanctl provides a portable, | |
125 | complete IKE configuration and control interface for the command line. | |
73303700 | 126 | The first six swanctl example scenarios have been added. |
b30c09ea | 127 | |
6048d773 AS |
128 | - The SWID IMV implements a JSON-based REST API which allows the exchange |
129 | of SWID tags and Software IDs with the strongTNC policy manager. | |
130 | ||
37cb91d7 | 131 | - The SWID IMC can extract all installed packages from the dpkg (Debian, |
3d2b36b8 TB |
132 | Ubuntu, Linux Mint etc.), rpm (Fedora, RedHat, OpenSUSE, etc.), or |
133 | pacman (Arch Linux, Manjaro, etc.) package managers, respectively, using the | |
134 | swidGenerator (https://github.com/strongswan/swidGenerator) which generates | |
135 | SWID tags according to the new ISO/IEC 19770-2:2014 standard. | |
37cb91d7 AS |
136 | |
137 | - All IMVs now share the access requestor ID, device ID and product info | |
138 | of an access requestor via a common imv_session object. | |
139 | ||
9b9d5223 AS |
140 | - The Attestation IMC/IMV pair supports the IMA-NG measurement format |
141 | introduced with the Linux 3.13 kernel. | |
142 | ||
41a4d5a4 AS |
143 | - The aikgen tool generates an Attestation Identity Key bound to a TPM. |
144 | ||
03b5def0 | 145 | - Implemented the PT-EAP transport protocol (RFC 7171) for Trusted Network |
6048d773 | 146 | Connect. |
03b5def0 | 147 | |
52d77f32 MW |
148 | - The ipsec.conf replay_window option defines connection specific IPsec replay |
149 | windows. Original patch courtesy of Zheng Zhong and Christophe Gouault from | |
150 | 6Wind. | |

153 | strongswan-5.1.3 |
154 | ---------------- | |
155 | ||
e59ce07b TB |
156 | - Fixed an authentication bypass vulnerability triggered by rekeying an |
157 | unestablished IKEv2 SA while it gets actively initiated. This allowed an | |
158 | attacker to trick a peer's IKE_SA state to established, without the need to | |
159 | provide any valid authentication credentials. The vulnerability has been | |
160 | registered as CVE-2014-2338. | |
161 | ||
8101e6aa MW |
162 | - The acert plugin evaluates X.509 Attribute Certificates. Group membership |
163 | information encoded as strings can be used to fulfill authorization checks | |
164 | defined with the rightgroups option. Attribute Certificates can be loaded | |
165 | locally or get exchanged in IKEv2 certificate payloads. | |
166 | ||
167 | - The pki command gained support to generate X.509 Attribute Certificates | |
168 | using the --acert subcommand, while the --print command supports the ac type. | |
169 | The openac utility has been removed in favor of the new pki functionality. | |
170 | ||
7dc7fdea MW |
171 | - The libtls TLS 1.2 implementation as used by EAP-(T)TLS and other protocols |
172 | has been extended by AEAD mode support, currently limited to AES-GCM. | |
173 | ||
8101e6aa | 174 | |
acc25f29 AS |
175 | strongswan-5.1.2 |
176 | ---------------- | |
177 | ||
c2d5add6 TB |
178 | - A new default configuration file layout is introduced. The new default |
179 | strongswan.conf file mainly includes config snippets from the strongswan.d | |
180 | and strongswan.d/charon directories (the latter containing snippets for all | |
181 | plugins). The snippets, with commented defaults, are automatically | |
182 | generated and installed, if they don't exist yet. They are also installed | |
183 | in $prefix/share/strongswan/templates so existing files can be compared to | |
184 | the current defaults. | |
185 | ||
186 | - As an alternative to the non-extensible charon.load setting, the plugins | |
187 | to load in charon (and optionally other applications) can now be determined | |
188 | via the charon.plugins.<name>.load setting for each plugin (enabled in the | |
189 | new default strongswan.conf file via the charon.load_modular option). | |
190 | The load setting optionally takes a numeric priority value that allows | |
191 | reordering the plugins (otherwise the default plugin order is preserved). | |
192 | ||
193 | - All strongswan.conf settings that were formerly defined in library specific | |
194 | "global" sections are now application specific (e.g. settings for plugins in | |
195 | libstrongswan.plugins can now be set only for charon in charon.plugins). | |
196 | The old options are still supported, which now allows to define defaults for | |
197 | all applications in the libstrongswan section. | |
198 | ||
acc25f29 AS |
199 | - The ntru libstrongswan plugin supports NTRUEncrypt as a post-quantum |
200 | computer IKE key exchange mechanism. The implementation is based on the | |
201 | ntru-crypto library from the NTRUOpenSourceProject. The supported security | |
202 | strengths are ntru112, ntru128, ntru192, and ntru256. Since the private DH | |
203 | group IDs 1030..1033 have been assigned, the strongSwan Vendor ID must be | |
204 | sent (charon.send_vendor_id = yes) in order to use NTRU. | |
205 | ||
800b361e AS |
206 | - Defined a TPMRA remote attestation workitem and added support for it to the |
207 | Attestation IMV. | |
208 | ||
c2d5add6 TB |
209 | - Compatibility issues between IPComp (compress=yes) and leftfirewall=yes as |
210 | well as multiple subnets in left|rightsubnet have been fixed. | |
211 | ||
572582f5 MW |
212 | - When enabling its "session" strongswan.conf option, the xauth-pam plugin opens |
213 | and closes a PAM session for each established IKE_SA. Patch courtesy of | |
214 | Andrea Bonomi. | |
acc25f29 | 215 | |
0cec570a MW |
216 | - The strongSwan unit testing framework has been rewritten without the "check" |
217 | dependency for improved flexibility and portability. It now properly supports | |
218 | multi-threaded and memory leak testing and brings a bunch of new test cases. | |
219 | ||
220 | ||
2b32884d AS |
221 | strongswan-5.1.1 |
222 | ---------------- | |
223 | ||
7b8fbd74 AS |
224 | - Fixed a denial-of-service vulnerability and potential authorization bypass |
225 | triggered by a crafted ID_DER_ASN1_DN ID payload. The cause is an insufficient | |
226 | length check when comparing such identities. The vulnerability has been | |
227 | registered as CVE-2013-6075. | |
228 | ||
229 | - Fixed a denial-of-service vulnerability triggered by a crafted IKEv1 | |
230 | fragmentation payload. The cause is a NULL pointer dereference. The | |
231 | vulnerability has been registered as CVE-2013-6076. | |
232 | ||
2b32884d | 233 | - The lean stand-alone pt-tls-client can set up a RFC 6876 PT-TLS session |
1c1ba803 TB |
234 | with a strongSwan policy enforcement point which uses the tnc-pdp charon |
235 | plugin. | |
2b32884d | 236 | |
fa2f6aa1 AS |
237 | - The new TCG TNC SWID IMC/IMV pair supports targeted SWID requests for either |
238 | full SWID Tag or concise SWID Tag ID inventories. | |
239 | ||
38fb8e4e MW |
240 | - The XAuth backend in eap-radius now supports multiple XAuth exchanges for |
241 | different credential types and display messages. All user input gets | |
242 | concatenated and verified with a single User-Password RADIUS attribute on | |
243 | the AAA. With an AAA supporting it, one for example can implement | |
244 | Password+Token authentication with proper dialogs on iOS and OS X clients. | |
245 | ||
246 | - charon supports IKEv1 Mode Config exchange in push mode. The ipsec.conf | |
247 | modeconfig=push option enables it for both client and server, the same way | |
248 | as pluto used it. | |
249 | ||
390d2b50 MW |
250 | - Using the "ah" ipsec.conf keyword on both IKEv1 and IKEv2 connections, |
251 | charon can negotiate and install Security Associations integrity-protected by | |
252 | the Authentication Header protocol. Supported are plain AH(+IPComp) SAs only, | |
253 | but not the deprecated RFC2401 style ESP+AH bundles. | |
254 | ||
1c1ba803 TB |
255 | - The generation of initialization vectors for IKE and ESP (when using libipsec) |
256 | is now modularized and IVs for e.g. AES-GCM are now correctly allocated | |
257 | sequentially, while other algorithms like AES-CBC still use random IVs. | |
258 | ||
38fb8e4e MW |
259 | - The left and right options in ipsec.conf can take multiple address ranges |
260 | and subnets. This allows connection matching against a larger set of | |
261 | addresses, for example to use a different connection for clients connecting | |
262 | from a internal network. | |
263 | ||
34dff30c AS |
264 | - For all those who have a queasy feeling about the NIST elliptic curve set, |
265 | the Brainpool curves introduced for use with IKE by RFC 6932 might be a | |
266 | more trustworthy alternative. | |
267 | ||
390d2b50 MW |
268 | - The kernel-libipsec userland IPsec backend now supports usage statistics, |
269 | volume based rekeying and accepts ESPv3 style TFC padded packets. | |
270 | ||
1c1ba803 TB |
271 | - With two new strongswan.conf options fwmarks can be used to implement |
272 | host-to-host tunnels with kernel-libipsec. | |
273 | ||
38fb8e4e MW |
274 | - load-tester supports transport mode connections and more complex traffic |
275 | selectors, including such using unique ports for each tunnel. | |
2b32884d | 276 | |
1c1ba803 TB |
277 | - The new dnscert plugin provides support for authentication via CERT RRs that |
278 | are protected via DNSSEC. The plugin was created by Ruslan N. Marchenko. | |
279 | ||
280 | - The eap-radius plugin supports forwarding of several Cisco Unity specific | |
281 | RADIUS attributes in corresponding configuration payloads. | |
282 | ||
283 | - Database transactions are now abstracted and implemented by the two backends. | |
284 | If you use MySQL make sure all tables use the InnoDB engine. | |
285 | ||
390d2b50 MW |
286 | - libstrongswan now can provide an experimental custom implementation of the |
287 | printf family functions based on klibc if neither Vstr nor glibc style printf | |
288 | hooks are available. This can avoid the Vstr dependency on some systems at | |
289 | the cost of slower and less complete printf functions. | |
290 | ||

40b0a15c MW |
292 | strongswan-5.1.0 |
293 | ---------------- | |
294 | ||
3a938a6f TB |
295 | - Fixed a denial-of-service vulnerability triggered by specific XAuth usernames |
296 | and EAP identities (since 5.0.3), and PEM files (since 4.1.11). The crash | |
297 | was caused by insufficient error handling in the is_asn1() function. | |
298 | The vulnerability has been registered as CVE-2013-5018. | |
299 | ||
40b0a15c MW |
300 | - The new charon-cmd command line IKE client can establish road warrior |
301 | connections using IKEv1 or IKEv2 with different authentication profiles. | |
302 | It does not depend on any configuration files and can be configured using a | |
303 | few simple command line options. | |
304 | ||
305 | - The kernel-pfroute networking backend has been greatly improved. It now | |
78e6f69e | 306 | can install virtual IPs on TUN devices on OS X and FreeBSD, allowing these |
40b0a15c MW |
307 | systems to act as a client in common road warrior scenarios. |
308 | ||
78e6f69e TB |
309 | - The new kernel-libipsec plugin uses TUN devices and libipsec to provide IPsec |
310 | processing in userland on Linux, FreeBSD and Mac OS X. | |
311 | ||
68957d18 MW |
312 | - The eap-radius plugin can now serve as an XAuth backend called xauth-radius, |
313 | directly verifying XAuth credentials using RADIUS User-Name/User-Password | |
314 | attributes. This is more efficient than the existing xauth-eap+eap-radius | |
315 | combination, and allows RADIUS servers without EAP support to act as AAA | |
316 | backend for IKEv1. | |
317 | ||
78e6f69e | 318 | - The new osx-attr plugin installs configuration attributes (currently DNS |
2334ae56 MW |
319 | servers) via SystemConfiguration on Mac OS X. The keychain plugin provides |
320 | certificates from the OS X keychain service. | |
78e6f69e TB |
321 | |
322 | - The sshkey plugin parses SSH public keys, which, together with the --agent | |
323 | option for charon-cmd, allows the use of ssh-agent for authentication. | |
324 | To configure SSH keys in ipsec.conf the left|rightrsasigkey options are | |
325 | replaced with left|rightsigkey, which now take public keys in one of three | |
326 | formats: SSH (RFC 4253, ssh: prefix), DNSKEY (RFC 3110, dns: prefix), and | |
327 | PKCS#1 (the default, no prefix). | |
328 | ||
329 | - Extraction of certificates and private keys from PKCS#12 files is now provided | |
330 | by the new pkcs12 plugin or the openssl plugin. charon-cmd (--p12) as well | |
331 | as charon (via P12 token in ipsec.secrets) can make use of this. | |
332 | ||
40b0a15c MW |
333 | - IKEv2 can now negotiate transport mode and IPComp in NAT situations. |
334 | ||
3a938a6f | 335 | - IKEv2 exchange initiators now properly close an established IKE or CHILD_SA |
40b0a15c MW |
336 | on error conditions using an additional exchange, keeping state in sync |
337 | between peers. | |
338 | ||
226f34e0 | 339 | - Using a SQL database interface a Trusted Network Connect (TNC) Policy Manager |
78e6f69e TB |
340 | can generate specific measurement workitems for an arbitrary number of |
341 | Integrity Measurement Verifiers (IMVs) based on the history of the VPN user | |
342 | and/or device. | |
343 | ||
344 | - Several core classes in libstrongswan are now tested with unit tests. These | |
345 | can be enabled with --enable-unit-tests and run with 'make check'. Coverage | |
346 | reports can be generated with --enable-coverage and 'make coverage' (this | |
347 | disables any optimization, so it should not be enabled when building | |
348 | production releases). | |
349 | ||
56b753ca MW |
350 | - The leak-detective developer tool has been greatly improved. It works much |
351 | faster/stabler with multiple threads, does not use deprecated malloc hooks | |
352 | anymore and has been ported to OS X. | |
353 | ||
78e6f69e TB |
354 | - chunk_hash() is now based on SipHash-2-4 with a random key. This provides |
355 | better distribution and prevents hash flooding attacks when used with | |
356 | hashtables. | |
357 | ||
358 | - All default plugins implement the get_features() method to define features | |
359 | and their dependencies. The plugin loader has been improved, so that plugins | |
360 | in a custom load statement can be ordered freely or to express preferences | |
361 | without being affected by dependencies between plugin features. | |
362 | ||
c3b8335c MW |
363 | - A centralized thread can take care for watching multiple file descriptors |
364 | concurrently. This removes the need for a dedicated listener threads in | |
365 | various plugins. The number of "reserved" threads for such tasks has been | |
366 | reduced to about five, depending on the plugin configuration. | |
367 | ||
368 | - Plugins that can be controlled by a UNIX socket IPC mechanism gained network | |
369 | transparency. Third party applications querying these plugins now can use | |
370 | TCP connections from a different host. | |
371 | ||
78e6f69e | 372 | - libipsec now supports AES-GCM. |

376 | ---------------- | |
377 | ||
378 | - Fixed a security vulnerability in the openssl plugin which was reported by | |
379 | Kevin Wojtysiak. The vulnerability has been registered as CVE-2013-2944. | |
380 | Before the fix, if the openssl plugin's ECDSA signature verification was used, | |
381 | due to a misinterpretation of the error code returned by the OpenSSL | |
382 | ECDSA_verify() function, an empty or zeroed signature was accepted as a | |
383 | legitimate one. | |
384 | ||
385 | - The handling of a couple of other non-security relevant openssl return codes | |
386 | was fixed as well. | |
387 | ||
388 | - The tnc_ifmap plugin now publishes virtual IPv4 and IPv6 addresses via its | |
389 | TCG TNC IF-MAP 2.1 interface. | |
390 | ||
391 | - The charon.initiator_only option causes charon to ignore IKE initiation | |
392 | requests. | |
393 | ||
bec5bf02 AS |
394 | - The openssl plugin can now use the openssl-fips library. |
395 | ||

d69eb037 TB |
397 | strongswan-5.0.3 |
398 | ---------------- | |
399 | ||
400 | - The new ipseckey plugin enables authentication based on trustworthy public | |
401 | keys stored as IPSECKEY resource records in the DNS and protected by DNSSEC. | |
402 | To do so it uses a DNSSEC enabled resolver, like the one provided by the new | |
403 | unbound plugin, which is based on libldns and libunbound. Both plugins were | |
404 | created by Reto Guadagnini. | |
405 | ||
1fc609fe AS |
406 | - Implemented the TCG TNC IF-IMV 1.4 draft making access requestor identities |
407 | available to an IMV. The OS IMV stores the AR identity together with the | |
408 | device ID in the attest database. | |
409 | ||
410 | - The openssl plugin now uses the AES-NI accelerated version of AES-GCM | |
411 | if the hardware supports it. | |
7a93844f | 412 | |
96776d6f MW |
413 | - The eap-radius plugin can now assign virtual IPs to IKE clients using the |
414 | Framed-IP-Address attribute by using the "%radius" named pool in the | |
415 | rightsourceip ipsec.conf option. Cisco Banner attributes are forwarded to | |
416 | Unity-capable IKEv1 clients during mode config. charon now sends Interim | |
417 | Accounting updates if requested by the RADIUS server, reports | |
418 | sent/received packets in Accounting messages, and adds a Terminate-Cause | |
419 | to Accounting-Stops. | |
420 | ||
421 | - The recently introduced "ipsec listcounters" command can report connection | |
422 | specific counters by passing a connection name, and global or connection | |
423 | counters can be reset by the "ipsec resetcounters" command. | |
424 | ||
425 | - The strongSwan libpttls library provides an experimental implementation of | |
426 | PT-TLS (RFC 6876), a Posture Transport Protocol over TLS. | |
427 | ||
428 | - The charon systime-fix plugin can disable certificate lifetime checks on | |
429 | embedded systems if the system time is obviously out of sync after bootup. | |
430 | Certificates lifetimes get checked once the system time gets sane, closing | |
431 | or reauthenticating connections using expired certificates. | |
432 | ||
433 | - The "ikedscp" ipsec.conf option can set DiffServ code points on outgoing | |
434 | IKE packets. | |
7a93844f | 435 | |
e34666a4 TB |
436 | - The new xauth-noauth plugin allows to use basic RSA or PSK authentication with |
437 | clients that cannot be configured without XAuth authentication. The plugin | |
438 | simply concludes the XAuth exchange successfully without actually performing | |
439 | any authentication. Therefore, to use this backend it has to be selected | |
440 | explicitly with rightauth2=xauth-noauth. | |
441 | ||
db50a35a RB |
442 | - The new charon-tkm IKEv2 daemon delegates security critical operations to a |
443 | separate process. This has the benefit that the network facing daemon has no | |
444 | knowledge of keying material used to protect child SAs. Thus subverting | |
445 | charon-tkm does not result in the compromise of cryptographic keys. | |
446 | The extracted functionality has been implemented from scratch in a minimal TCB | |
447 | (trusted computing base) in the Ada programming language. Further information | |
448 | can be found at http://www.codelabs.ch/tkm/. | |
449 | ||
c2a5e7bc AS |
450 | strongswan-5.0.2 |
451 | ---------------- | |
452 | ||
453 | - Implemented all IETF Standard PA-TNC attributes and an OS IMC/IMV | |
454 | pair using them to transfer operating system information. | |
455 | ||
a19d5913 MW |
456 | - The new "ipsec listcounters" command prints a list of global counter values |
457 | about received and sent IKE messages and rekeyings. | |
458 | ||
343e9989 MW |
459 | - A new lookip plugin can perform fast lookup of tunnel information using a |
460 | clients virtual IP and can send notifications about established or deleted | |
461 | tunnels. The "ipsec lookip" command can be used to query such information | |
462 | or receive notifications. | |
463 | ||
ecdd5aed MW |
464 | - The new error-notify plugin catches some common error conditions and allows |
465 | an external application to receive notifications for them over a UNIX socket. | |
466 | ||
6910e5c7 MW |
467 | - IKE proposals can now use a PRF algorithm different to that defined for |
468 | integrity protection. If an algorithm with a "prf" prefix is defined | |
469 | explicitly (such as prfsha1 or prfsha256), no implicit PRF algorithm based on | |
470 | the integrity algorithm is added to the proposal. | |
c2a5e7bc | 471 | |
8fc7bbc6 MW |
472 | - The pkcs11 plugin can now load leftcert certificates from a smartcard for a |
473 | specific ipsec.conf conn section and cacert CA certificates for a specific ca | |
474 | section. | |
475 | ||
78b2a2b1 MW |
476 | - The load-tester plugin gained additional options for certificate generation |
477 | and can load keys and multiple CA certificates from external files. It can | |
478 | install a dedicated outer IP address for each tunnel and tunnel initiation | |
479 | batches can be triggered and monitored externally using the | |
480 | "ipsec load-tester" tool. | |
481 | ||
cc0cc3b5 MW |
482 | - PKCS#7 container parsing has been modularized, and the openssl plugin |
483 | gained an alternative implementation to decrypt and verify such files. | |
484 | In contrast to our own DER parser, OpenSSL can handle BER files, which is | |
485 | required for interoperability of our scepclient with EJBCA. | |
486 | ||
f31b4180 TB |
487 | - Support for the proprietary IKEv1 fragmentation extension has been added. |
488 | Fragments are always handled on receipt but only sent if supported by the peer | |
489 | and if enabled with the new fragmentation ipsec.conf option. | |
490 | ||
0e0870ae MW |
491 | - IKEv1 in charon can now parse certificates received in PKCS#7 containers and |
492 | supports NAT traversal as used by Windows clients. Patches courtesy of | |
493 | Volker Rümelin. | |
494 | ||
2f0441a3 MW |
495 | - The new rdrand plugin provides a high quality / high performance random |
496 | source using the Intel rdrand instruction found on Ivy Bridge processors. | |
497 | ||
73791223 TB |
498 | - The integration test environment was updated and now uses KVM and reproducible |
499 | guest images based on Debian. | |
500 | ||

ecfd714c AS |
502 | strongswan-5.0.1 |
503 | ---------------- | |
504 | ||
6f93927b AS |
505 | - Introduced the sending of the standard IETF Assessment Result |
506 | PA-TNC attribute by all strongSwan Integrity Measurement Verifiers. | |
507 | ||
ecfd714c AS |
508 | - Extended PTS Attestation IMC/IMV pair to provide full evidence of |
509 | the Linux IMA measurement process. All pertinent file information | |
6f93927b | 510 | of a Linux OS can be collected and stored in an SQL database. |
ecfd714c AS |
511 | |
512 | - The PA-TNC and PB-TNC protocols can now process huge data payloads | |
513 | >64 kB by distributing PA-TNC attributes over multiple PA-TNC messages | |
514 | and these messages over several PB-TNC batches. As long as no | |
6f93927b | 515 | consolidated recommandation from all IMVs can be obtained, the TNC |
ecfd714c AS |
516 | server requests more client data by sending an empty SDATA batch. |
517 | ||
804d702b MW |
518 | - The rightgroups2 ipsec.conf option can require group membership during |
519 | a second authentication round, for example during XAuth authentication | |
520 | against a RADIUS server. | |
521 | ||
3423b3a8 MW |
522 | - The xauth-pam backend can authenticate IKEv1 XAuth and Hybrid authenticated |
523 | clients against any PAM service. The IKEv2 eap-gtc plugin does not use | |
524 | PAM directly anymore, but can use any XAuth backend to verify credentials, | |
525 | including xauth-pam. | |
526 | ||
cc48f360 MW |
527 | - The new unity plugin brings support for some parts of the IKEv1 Cisco Unity |
528 | Extension. As client, charon narrows traffic selectors to the received | |
529 | Split-Include attributes and automatically installs IPsec bypass policies | |
530 | for received Local-LAN attributes. As server, charon sends Split-Include | |
531 | attributes for leftsubnet definitions containing multiple subnets to Unity- | |
532 | aware clients. | |
533 | ||
cbe244a5 TB |
534 | - An EAP-Nak payload is returned by clients if the gateway requests an EAP |
535 | method that the client does not support. Clients can also request a specific | |
536 | EAP method by configuring that method with leftauth. | |
537 | ||
538 | - The eap-dynamic plugin handles EAP-Nak payloads returned by clients and uses | |
539 | these to select a different EAP method supported/requested by the client. | |
540 | The plugin initially requests the first registered method or the first method | |
541 | configured with charon.plugins.eap-dynamic.preferred. | |
542 | ||
e76f3d0d MW |
543 | - The new left/rightdns options specify connection specific DNS servers to |
544 | request/respond in IKEv2 configuration payloads or IKEv2 mode config. leftdns | |
545 | can be any (comma separated) combination of %config4 and %config6 to request | |
546 | multiple servers, both for IPv4 and IPv6. rightdns takes a list of DNS server | |
547 | IP addresses to return. | |
548 | ||
69e056a2 MW |
549 | - The left/rightsourceip options now accept multiple addresses or pools. |
550 | leftsourceip can be any (comma separated) combination of %config4, %config6 | |
551 | or fixed IP addresses to request. rightsourceip accepts multiple explicitly | |
552 | specified or referenced named pools. | |
553 | ||
554 | - Multiple connections can now share a single address pool when they use the | |
555 | same definition in one of the rightsourceip pools. | |
556 | ||
4a025539 TB |
557 | - The options charon.interfaces_ignore and charon.interfaces_use allow one to |
558 | configure the network interfaces used by the daemon. | |
559 | ||
560 | - The kernel-netlink plugin supports the charon.install_virtual_ip_on option, | |
561 | which specifies the interface on which virtual IP addresses will be installed. | |
562 | If it is not specified the current behavior of using the outbound interface | |
563 | is preserved. | |
564 | ||
565 | - The kernel-netlink plugin tries to keep the current source address when | |
566 | looking for valid routes to reach other hosts. | |
567 | ||
804d702b MW |
568 | - The autotools build has been migrated to use a config.h header. strongSwan |
569 | development headers will get installed during "make install" if | |
570 | --with-dev-headers has been passed to ./configure. | |
571 | ||
572 | - All crypto primitives gained return values for most operations, allowing | |
573 | crypto backends to fail, for example when using hardware accelerators. | |
ecfd714c | 574 | |

576 | strongswan-5.0.0 |
577 | ---------------- | |
578 | ||
794cdbc5 MW |
579 | - The charon IKE daemon gained experimental support for the IKEv1 protocol. |
580 | Pluto has been removed from the 5.x series, and unless strongSwan is | |
581 | configured with --disable-ikev1 or --disable-ikev2, charon handles both | |
582 | keying protocols. The feature-set of IKEv1 in charon is almost on par with | |
583 | pluto, but currently does not support AH or bundled AH+ESP SAs. Beside | |
584 | RSA/ECDSA, PSK and XAuth, charon also supports the Hybrid authentication | |
585 | mode. Informations for interoperability and migration is available at | |
586 | http://wiki.strongswan.org/projects/strongswan/wiki/CharonPlutoIKEv1. | |
587 | ||
d55c2404 TB |
588 | - Charon's bus_t has been refactored so that loggers and other listeners are |
589 | now handled separately. The single lock was previously cause for deadlocks | |
590 | if extensive listeners, such as the one provided by the updown plugin, wanted | |
591 | to acquire locks that were held by other threads which in turn tried to log | |
592 | messages, and thus were waiting to acquire the same lock currently held by | |
593 | the thread calling the listener. | |
594 | The implemented changes also allow the use of a read/write-lock for the | |
595 | loggers which increases performance if multiple loggers are registered. | |
596 | Besides several interface changes this last bit also changes the semantics | |
597 | for loggers as these may now be called by multiple threads at the same time. | |
598 | ||
ed7186cb TB |
599 | - Source routes are reinstalled if interfaces are reactivated or IP addresses |
600 | reappear. | |
601 | ||
f97c269e TB |
602 | - The thread pool (processor_t) now has more control over the lifecycle of |
603 | a job (see job.h for details). In particular, it now controls the destruction | |
604 | of jobs after execution and the cancellation of jobs during shutdown. Due to | |
605 | these changes the requeueing feature, previously available to callback_job_t | |
606 | only, is now available to all jobs (in addition to a new rescheduling | |
607 | feature). | |
608 | ||
5a6e5e0d MW |
609 | - In addition to trustchain key strength definitions for different public key |
610 | systems, the rightauth option now takes a list of signature hash algorithms | |
611 | considered save for trustchain validation. For example, the setting | |
612 | rightauth=rsa-2048-ecdsa-256-sha256-sha384-sha512 requires a trustchain | |
613 | that uses at least RSA-2048 or ECDSA-256 keys and certificate signatures | |
614 | using SHA-256 or better. | |
615 | ||
d55c2404 | 616 | |
93d9a02e TB |
617 | strongswan-4.6.4 |
618 | ---------------- | |
619 | ||
620 | - Fixed a security vulnerability in the gmp plugin. If this plugin was used | |
621 | for RSA signature verification an empty or zeroed signature was handled as | |
622 | a legitimate one. | |
623 | ||
624 | - Fixed several issues with reauthentication and address updates. | |
625 | ||
626 | ||
c224f765 AS |
627 | strongswan-4.6.3 |
628 | ---------------- | |
629 | ||
630 | - The tnc-pdp plugin implements a RADIUS server interface allowing | |
631 | a strongSwan TNC server to act as a Policy Decision Point. | |
632 | ||
4bc7577d MW |
633 | - The eap-radius authentication backend enforces Session-Timeout attributes |
634 | using RFC4478 repeated authentication and acts upon RADIUS Dynamic | |
635 | Authorization extensions, RFC 5176. Currently supported are disconnect | |
636 | requests and CoA messages containing a Session-Timeout. | |
637 | ||
638 | - The eap-radius plugin can forward arbitrary RADIUS attributes from and to | |
639 | clients using custom IKEv2 notify payloads. The new radattr plugin reads | |
640 | attributes to include from files and prints received attributes to the | |
641 | console. | |
c224f765 AS |
642 | |
643 | - Added support for untruncated MD5 and SHA1 HMACs in ESP as used in | |
644 | RFC 4595. | |
645 | ||
d7590217 TB |
646 | - The cmac plugin implements the AES-CMAC-96 and AES-CMAC-PRF-128 algorithms |
647 | as defined in RFC 4494 and RFC 4615, respectively. | |
648 | ||
4e2e77d5 | 649 | - The resolve plugin automatically installs nameservers via resolvconf(8), |
a281494a | 650 | if it is installed, instead of modifying /etc/resolv.conf directly. |
c224f765 | 651 | |
5f1931ad AS |
652 | - The IKEv2 charon daemon supports now raw RSA public keys in RFC 3110 |
653 | DNSKEY and PKCS#1 file format. | |
654 | ||
655 | ||
60e99b37 AS |
656 | strongswan-4.6.2 |
657 | ---------------- | |
658 | ||
659 | - Upgraded the TCG IF-IMC and IF-IMV C API to the upcoming version 1.3 | |
660 | which supports IF-TNCCS 2.0 long message types, the exclusive flags | |
661 | and multiple IMC/IMV IDs. Both the TNC Client and Server as well as | |
662 | the "Test", "Scanner", and "Attestation" IMC/IMV pairs were updated. | |
663 | ||
664 | - Fully implemented the "TCG Attestation PTS Protocol: Binding to IF-M" | |
665 | standard (TLV-based messages only). TPM-based remote attestation of | |
de4a0c83 AS |
666 | Linux IMA (Integrity Measurement Architecture) possible. Measurement |
667 | reference values are automatically stored in an SQLite database. | |
60e99b37 | 668 | |
a345aa26 MW |
669 | - The EAP-RADIUS authentication backend supports RADIUS accounting. It sends |
670 | start/stop messages containing Username, Framed-IP and Input/Output-Octets | |
671 | attributes and has been tested against FreeRADIUS and Microsoft NPS. | |
60e99b37 | 672 | |
de4a0c83 AS |
673 | - Added support for PKCS#8 encoded private keys via the libstrongswan |
674 | pkcs8 plugin. This is the default format used by some OpenSSL tools since | |
675 | version 1.0.0 (e.g. openssl req with -keyout). | |
dcefa267 | 676 | |
a8958012 MW |
677 | - Added session resumption support to the strongSwan TLS stack. |
678 | ||
de4a0c83 | 679 | |
acb92cb4 AS |
680 | strongswan-4.6.1 |
681 | ---------------- | |
682 | ||
683 | - Because of changing checksums before and after installation which caused | |
684 | the integrity tests to fail we avoided directly linking libsimaka, libtls and | |
685 | libtnccs to those libcharon plugins which make use of these dynamic libraries. | |
18f85b66 AS |
686 | Instead we linked the libraries to the charon daemon. Unfortunately Ubuntu |
687 | 11.10 activated the --as-needed ld option which discards explicit links | |
688 | to dynamic libraries that are not actually used by the charon daemon itself, | |
689 | thus causing failures during the loading of the plugins which depend on these | |
690 | libraries for resolving external symbols. | |
acb92cb4 AS |
691 | |
692 | - Therefore our approach of computing integrity checksums for plugins had to be | |
693 | changed radically by moving the hash generation from the compilation to the | |
694 | post-installation phase. | |

5a2e2e0b AS |
698 | ---------------- |
699 | ||
37276728 MW |
700 | - The new libstrongswan certexpire plugin collects expiration information of |
701 | all used certificates and exports them to CSV files. It either directly | |
702 | exports them or uses cron style scheduling for batch exports. | |
703 | ||
704 | - starter passes unresolved hostnames to charon, allowing it to do name | |
705 | resolution not before the connection attempt. This is especially useful with | |
706 | connections between hosts using dynamic IP addresses. Thanks to Mirko Parthey | |
707 | for the initial patch. | |
708 | ||
5fd8e530 TB |
709 | - The android plugin can now be used without the Android frontend patch and |
710 | provides DNS server registration and logging to logcat. | |
711 | ||
712 | - Pluto and starter (plus stroke and whack) have been ported to Android. | |
713 | ||
602ee58e TB |
714 | - Support for ECDSA private and public key operations has been added to the |
715 | pkcs11 plugin. The plugin now also provides DH and ECDH via PKCS#11 and can | |
716 | use tokens as random number generators (RNG). By default only private key | |
717 | operations are enabled, more advanced features have to be enabled by their | |
718 | option in strongswan.conf. This also applies to public key operations (even | |
719 | for keys not stored on the token) which were enabled by default before. | |
720 | ||
37276728 MW |
721 | - The libstrongswan plugin system now supports detailed plugin dependencies. |
722 | Many plugins have been extended to export its capabilities and requirements. | |
723 | This allows the plugin loader to resolve plugin loading order automatically, | |
724 | and in future releases, to dynamically load the required features on demand. | |
725 | Existing third party plugins are source (but not binary) compatible if they | |
726 | properly initialize the new get_features() plugin function to NULL. | |
727 | ||
fd81ac05 AS |
728 | - The tnc-ifmap plugin implements a TNC IF-MAP 2.0 client which can deliver |
729 | metadata about IKE_SAs via a SOAP interface to a MAP server. The tnc-ifmap | |
730 | plugin requires the Apache Axis2/C library. | |
731 | ||
37276728 | 732 | |
5d179d19 AS |
733 | strongswan-4.5.3 |
734 | ---------------- | |
735 | ||
a7edbd21 | 736 | - Our private libraries (e.g. libstrongswan) are not installed directly in |
b18a697a AS |
737 | prefix/lib anymore. Instead a subdirectory is used (prefix/lib/ipsec/ by |
738 | default). The plugins directory is also moved from libexec/ipsec/ to that | |
a7edbd21 TB |
739 | directory. |
740 | ||
b18a697a AS |
741 | - The dynamic IMC/IMV libraries were moved from the plugins directory to |
742 | a new imcvs directory in the prefix/lib/ipsec/ subdirectory. | |
743 | ||
107ea60f TB |
744 | - Job priorities were introduced to prevent thread starvation caused by too |
745 | many threads handling blocking operations (such as CRL fetching). Refer to | |
746 | strongswan.conf(5) for details. | |
747 | ||
748 | - Two new strongswan.conf options allow to fine-tune performance on IKEv2 | |
749 | gateways by dropping IKE_SA_INIT requests on high load. | |
750 | ||
f8799170 | 751 | - IKEv2 charon daemon supports start PASS and DROP shunt policies |
b18a697a | 752 | preventing traffic to go through IPsec connections. Installation of the |
107ea60f TB |
753 | shunt policies either via the XFRM netfilter or PFKEYv2 IPsec kernel |
754 | interfaces. | |
f8799170 | 755 | |
93095183 TB |
756 | - The history of policies installed in the kernel is now tracked so that e.g. |
757 | trap policies are correctly updated when reauthenticated SAs are terminated. | |
758 | ||
b18a697a AS |
759 | - IMC/IMV Scanner pair implementing the RFC 5792 PA-TNC (IF-M) protocol. |
760 | Using "netstat -l" the IMC scans open listening ports on the TNC client | |
761 | and sends a port list to the IMV which based on a port policy decides if | |
762 | the client is admitted to the network. | |

4876f896 MW |
768 | - The IKEv2 close action does not use the same value as the ipsec.conf dpdaction |
769 | setting, but the value defined by its own closeaction keyword. The action | |
770 | is triggered if the remote peer closes a CHILD_SA unexpectedly. | |

774 | ---------------- | |
775 | ||
320e98c2 MW |
776 | - The whitelist plugin for the IKEv2 daemon maintains an in-memory identity |
777 | whitelist. Any connection attempt of peers not whitelisted will get rejected. | |
778 | The 'ipsec whitelist' utility provides a simple command line frontend for | |
779 | whitelist administration. | |
780 | ||
92ebb7c5 | 781 | - The duplicheck plugin provides a specialized form of duplicate checking, |
5832d505 | 782 | doing a liveness check on the old SA and optionally notify a third party |
92ebb7c5 MW |
783 | application about detected duplicates. |
784 | ||
785 | - The coupling plugin permanently couples two or more devices by limiting | |
786 | authentication to previously used certificates. | |
787 | ||
6f2378c1 AS |
788 | - In the case that the peer config and child config don't have the same name |
789 | (usually in SQL database defined connections), ipsec up|route <peer config> | |
790 | starts|routes all associated child configs and ipsec up|route <child config> | |
791 | only starts|routes the specific child config. | |
792 | ||
6ca05fe2 AS |
793 | - fixed the encoding and parsing of X.509 certificate policy statements (CPS). |
794 | ||
1ee7440b AS |
795 | - Duncan Salerno contributed the eap-sim-pcsc plugin implementing a |
796 | pcsc-lite based SIM card backend. | |
797 | ||
798 | - The eap-peap plugin implements the EAP PEAP protocol. Interoperates | |
2778b664 | 799 | successfully with a FreeRADIUS server and Windows 7 Agile VPN clients. |
1ee7440b | 800 | |
cf6ca6d7 MW |
801 | - The IKEv2 daemon charon rereads strongswan.conf on SIGHUP and instructs |
802 | all plugins to reload. Currently only the eap-radius and the attr plugins | |
803 | support configuration reloading. | |
804 | ||
d3d21c29 MW |
805 | - Added userland support to the IKEv2 daemon for Extended Sequence Numbers |
806 | support coming with Linux 2.6.39. To enable ESN on a connection, add | |
807 | the 'esn' keyword to the proposal. The default proposal uses 32-bit sequence | |
808 | numbers only ('noesn'), and the same value is used if no ESN mode is | |
809 | specified. To negotiate ESN support with the peer, include both, e.g. | |
810 | esp=aes128-sha1-esn-noesn. | |
811 | ||
812 | - In addition to ESN, Linux 2.6.39 gained support for replay windows larger | |
813 | than 32 packets. The new global strongswan.conf option 'charon.replay_window' | |
814 | configures the size of the replay window, in packets. | |
815 | ||

817 | strongswan-4.5.1 |
818 | ---------------- | |
819 | ||
1b7e081b AS |
820 | - Sansar Choinyambuu implemented the RFC 5793 Posture Broker Protocol (BP) |
821 | compatible with Trusted Network Connect (TNC). The TNCCS 2.0 protocol | |
5cdaafef | 822 | requires the tnccs_20, tnc_imc and tnc_imv plugins but does not depend |
1b7e081b AS |
823 | on the libtnc library. Any available IMV/IMC pairs conforming to the |
824 | Trusted Computing Group's TNC-IF-IMV/IMC 1.2 interface specification | |
e44817df | 825 | can be loaded via /etc/tnc_config. |
1b7e081b | 826 | |
5cdaafef AS |
827 | - Re-implemented the TNCCS 1.1 protocol by using the tnc_imc and tnc_imv |
828 | in place of the external libtnc library. | |
829 | ||
830 | - The tnccs_dynamic plugin loaded on a TNC server in addition to the | |
831 | tnccs_11 and tnccs_20 plugins, dynamically detects the IF-TNCCS | |
832 | protocol version used by a TNC client and invokes an instance of | |
833 | the corresponding protocol stack. | |
834 | ||
41ba5ce7 AS |
835 | - IKE and ESP proposals can now be stored in an SQL database using a |
836 | new proposals table. The start_action field in the child_configs | |
837 | tables allows the automatic starting or routing of connections stored | |
838 | in an SQL database. | |
839 | ||
1b7e081b AS |
840 | - The new certificate_authorities and certificate_distribution_points |
841 | tables make it possible to store CRL and OCSP Certificate Distribution | |
842 | points in an SQL database. | |
843 | ||
ae09bc62 TB |
844 | - The new 'include' statement allows to recursively include other files in |
845 | strongswan.conf. Existing sections and values are thereby extended and | |
846 | replaced, respectively. | |
847 | ||
848 | - Due to the changes in the parser for strongswan.conf, the configuration | |
849 | syntax for the attr plugin has changed. Previously, it was possible to | |
850 | specify multiple values of a specific attribute type by adding multiple | |
851 | key/value pairs with the same key (e.g. dns) to the plugins.attr section. | |
852 | Because values with the same key now replace previously defined values | |
853 | this is not possible anymore. As an alternative, multiple values can be | |
854 | specified by separating them with a comma (e.g. dns = 1.2.3.4, 2.3.4.5). | |
855 | ||
840e7044 AS |
856 | - ipsec listalgs now appends (set in square brackets) to each crypto |
857 | algorithm listed the plugin that registered the function. | |
858 | ||
e44817df MW |
859 | - Traffic Flow Confidentiality padding supported with Linux 2.6.38 can be used |
860 | by the IKEv2 daemon. The ipsec.conf 'tfc' keyword pads all packets to a given | |
861 | boundary, the special value '%mtu' pads all packets to the path MTU. | |
862 | ||
78a547c9 MW |
863 | - The new af-alg plugin can use various crypto primitives of the Linux Crypto |
864 | API using the AF_ALG interface introduced with 2.6.38. This removes the need | |
865 | for additional userland implementations of symmetric cipher, hash, hmac and | |
866 | xcbc algorithms. | |
44582075 | 867 | |
41ed0294 | 868 | - The IKEv2 daemon supports the INITIAL_CONTACT notify as initiator and |
983a5e88 MW |
869 | responder. The notify is sent when initiating configurations with a unique |
870 | policy, set in ipsec.conf via the global 'uniqueids' option. | |
41ed0294 | 871 | |
f0783464 MW |
872 | - The conftest conformance testing framework enables the IKEv2 stack to perform |
873 | many tests using a distinct tool and configuration frontend. Various hooks | |
874 | can alter reserved bits, flags, add custom notifies and proposals, reorder | |
875 | or drop messages and much more. It is enabled using the --enable-conftest | |
876 | ./configure switch. | |
877 | ||
77eee25f | 878 | - The new libstrongswan constraints plugin provides advanced X.509 constraint |
cf95d292 | 879 | checking. In addition to X.509 pathLen constraints, the plugin checks for |
77eee25f MW |
880 | nameConstraints and certificatePolicies, including policyMappings and |
881 | policyConstraints. The x509 certificate plugin and the pki tool have been | |
96c4addc MW |
882 | enhanced to support these extensions. The new left/rightcertpolicy ipsec.conf |
883 | connection keywords take OIDs a peer certificate must have. | |
884 | ||
885 | - The left/rightauth ipsec.conf keywords accept values with a minimum strength | |
886 | for trustchain public keys in bits, such as rsa-2048 or ecdsa-256. | |
77eee25f | 887 | |
fb1e7df1 MW |
888 | - The revocation and x509 libstrongswan plugins and the pki tool gained basic |
889 | support for delta CRLs. | |
890 | ||

892 | strongswan-4.5.0 |
893 | ---------------- | |
894 | ||
b14923ec AS |
895 | - IMPORTANT: the default keyexchange mode 'ike' is changing with release 4.5 |
896 | from 'ikev1' to 'ikev2', thus commemorating the five year anniversary of the | |
ac544be2 | 897 | IKEv2 RFC 4306 and its mature successor RFC 5996. The time has definitively |
b14923ec | 898 | come for IKEv1 to go into retirement and to cede its place to the much more |
ac544be2 | 899 | robust, powerful and versatile IKEv2 protocol! |
b14923ec | 900 | |
44582075 MW |
901 | - Added new ctr, ccm and gcm plugins providing Counter, Counter with CBC-MAC |
902 | and Galois/Counter Modes based on existing CBC implementations. These | |
903 | new plugins bring support for AES and Camellia Counter and CCM algorithms | |
904 | and the AES GCM algorithms for use in IKEv2. | |
905 | ||
84c9bc42 MW |
906 | - The new pkcs11 plugin brings full Smartcard support to the IKEv2 daemon and |
907 | the pki utility using one or more PKCS#11 libraries. It currently supports | |
61df42cc | 908 | RSA private and public key operations and loads X.509 certificates from |
84c9bc42 MW |
909 | tokens. |
910 | ||
a782b52f MW |
911 | - Implemented a general purpose TLS stack based on crypto and credential |
912 | primitives of libstrongswan. libtls supports TLS versions 1.0, 1.1 and 1.2, | |
913 | ECDHE-ECDSA/RSA, DHE-RSA and RSA key exchange algorithms and RSA/ECDSA based | |
914 | client authentication. | |
915 | ||
916 | - Based on libtls, the eap-tls plugin brings certificate based EAP | |
917 | authentication for client and server. It is compatible to Windows 7 IKEv2 | |
61df42cc | 918 | Smartcard authentication and the OpenSSL based FreeRADIUS EAP-TLS backend. |
a782b52f | 919 | |
8a1353fc AS |
920 | - Implemented the TNCCS 1.1 Trusted Network Connect protocol using the |
921 | libtnc library on the strongSwan client and server side via the tnccs_11 | |
922 | plugin and optionally connecting to a TNC@FHH-enhanced FreeRADIUS AAA server. | |
923 | Depending on the resulting TNC Recommendation, strongSwan clients are granted | |
924 | access to a network behind a strongSwan gateway (allow), are put into a | |
ac544be2 | 925 | remediation zone (isolate) or are blocked (none), respectively. Any number |
8a1353fc AS |
926 | of Integrity Measurement Collector/Verifier pairs can be attached |
927 | via the tnc-imc and tnc-imv charon plugins. | |
928 | ||
b3cabd1f TB |
929 | - The IKEv1 daemon pluto now uses the same kernel interfaces as the IKEv2 |
930 | daemon charon. As a result of this, pluto now supports xfrm marks which | |
931 | were introduced in charon with 4.4.1. | |
932 | ||
933 | - Applets for Maemo 5 (Nokia) allow to easily configure and control IKEv2 | |
934 | based VPN connections with EAP authentication on supported devices. | |
935 | ||
18a4f865 MW |
936 | - The RADIUS plugin eap-radius now supports multiple RADIUS servers for |
937 | redundant setups. Servers are selected by a defined priority, server load and | |
938 | availability. | |
939 | ||
940 | - The simple led plugin controls hardware LEDs through the Linux LED subsystem. | |
941 | It currently shows activity of the IKE daemon and is a good example how to | |
942 | implement a simple event listener. | |
943 | ||
b3cabd1f TB |
944 | - Improved MOBIKE behavior in several corner cases, for instance, if the |
945 | initial responder moves to a different address. | |
946 | ||
947 | - Fixed left-/rightnexthop option, which was broken since 4.4.0. | |
948 | ||
3f84e2d6 AS |
949 | - Fixed a bug not releasing a virtual IP address to a pool if the XAUTH |
950 | identity was different from the IKE identity. | |
951 | ||
f6032361 AS |
952 | - Fixed the alignment of ModeConfig messages on 4-byte boundaries in the |
953 | case where the attributes are not a multiple of 4 bytes (e.g. Cisco's | |
954 | UNITY_BANNER). | |
955 | ||
956 | - Fixed the interoperability of the socket_raw and socket_default | |
957 | charon plugins. | |
958 | ||
3f84e2d6 AS |
959 | - Added man page for strongswan.conf |
960 | ||
a782b52f | 961 | |
03b5e4d8 AS |
962 | strongswan-4.4.1 |
963 | ---------------- | |
964 | ||
ec40c02a | 965 | - Support of xfrm marks in IPsec SAs and IPsec policies introduced |
b22bb9f2 AS |
966 | with the Linux 2.6.34 kernel. For details see the example scenarios |
967 | ikev2/nat-two-rw-mark, ikev2/rw-nat-mark-in-out and ikev2/net2net-psk-dscp. | |
ec40c02a | 968 | |
b22bb9f2 | 969 | - The PLUTO_MARK_IN and PLUTO_ESP_ENC environment variables can be used |
b59340a2 AS |
970 | in a user-specific updown script to set marks on inbound ESP or |
971 | ESP_IN_UDP packets. | |
e87b78c6 | 972 | |
3561cc4b AS |
973 | - The openssl plugin now supports X.509 certificate and CRL functions. |
974 | ||
e9448cfc | 975 | - OCSP/CRL checking in IKEv2 has been moved to the revocation plugin, enabled |
b59340a2 | 976 | by default. Plase update manual load directives in strongswan.conf. |
e9448cfc MW |
977 | |
978 | - RFC3779 ipAddrBlock constraint checking has been moved to the addrblock | |
979 | plugin, disabled by default. Enable it and update manual load directives | |
980 | in strongswan.conf, if required. | |
981 | ||
7f3a9468 MW |
982 | - The pki utility supports CRL generation using the --signcrl command. |
983 | ||
984 | - The ipsec pki --self, --issue and --req commands now support output in | |
985 | PEM format using the --outform pem option. | |
986 | ||
03b5e4d8 AS |
987 | - The major refactoring of the IKEv1 Mode Config functionality now allows |
988 | the transport and handling of any Mode Config attribute. | |
989 | ||
e87b78c6 | 990 | - The RADIUS proxy plugin eap-radius now supports multiple servers. Configured |
b59340a2 AS |
991 | servers are chosen randomly, with the option to prefer a specific server. |
992 | Non-responding servers are degraded by the selection process. | |
e87b78c6 | 993 | |
c5c6f9b6 AS |
994 | - The ipsec pool tool manages arbitrary configuration attributes stored |
995 | in an SQL database. ipsec pool --help gives the details. | |
996 | ||
fe2434cf MW |
997 | - The new eap-simaka-sql plugin acts as a backend for EAP-SIM and EAP-AKA, |
998 | reading triplets/quintuplets from an SQL database. | |
999 | ||
c8bd06c7 MW |
1000 | - The High Availability plugin now supports a HA enabled in-memory address |
1001 | pool and Node reintegration without IKE_SA rekeying. The latter allows | |
1002 | clients without IKE_SA rekeying support to keep connected during | |
1003 | reintegration. Additionally, many other issues have been fixed in the ha | |
1004 | plugin. | |
1c1f132a | 1005 | |
c5c921bf MW |
1006 | - Fixed a potential remote code execution vulnerability resulting from |
1007 | the misuse of snprintf(). The vulnerability is exploitable by | |
1008 | unauthenticated users. | |
1009 | ||
03b5e4d8 | 1010 | |

1011 | strongswan-4.4.0 |
1012 | ---------------- | |
1013 | ||
d101a61f MW |
1014 | - The IKEv2 High Availability plugin has been integrated. It provides |
1015 | load sharing and failover capabilities in a cluster of currently two nodes, | |
1016 | based on an extend ClusterIP kernel module. More information is available at | |
1017 | http://wiki.strongswan.org/projects/strongswan/wiki/HighAvailability. | |
9235edc2 | 1018 | The development of the High Availability functionality was sponsored by |
d101a61f MW |
1019 | secunet Security Networks AG. |
1020 | ||
dd8cb2b0 AS |
1021 | - Added IKEv1 and IKEv2 configuration support for the AES-GMAC |
1022 | authentication-only ESP cipher. Our aes_gmac kernel patch or a Linux | |
1023 | 2.6.34 kernel is required to make AES-GMAC available via the XFRM | |
1024 | kernel interface. | |
1025 | ||
4590260b MW |
1026 | - Added support for Diffie-Hellman groups 22, 23 and 24 to the gmp, gcrypt |
1027 | and openssl plugins, usable by both pluto and charon. The new proposal | |
1028 | keywords are modp1024s160, modp2048s224 and modp2048s256. Thanks to Joy Latten | |
1029 | from IBM for his contribution. | |
1030 | ||
9235edc2 AS |
1031 | - The IKEv1 pluto daemon supports RAM-based virtual IP pools using |
1032 | the rightsourceip directive with a subnet from which addresses | |
1033 | are allocated. | |
1034 | ||
d6457833 AS |
1035 | - The ipsec pki --gen and --pub commands now allow the output of |
1036 | private and public keys in PEM format using the --outform pem | |
1037 | command line option. | |
1038 | ||
2d097a0b MW |
1039 | - The new DHCP plugin queries virtual IP addresses for clients from a DHCP |
1040 | server using broadcasts, or a defined server using the | |
1041 | charon.plugins.dhcp.server strongswan.conf option. DNS/WINS server information | |
1042 | is additionally served to clients if the DHCP server provides such | |
1043 | information. The plugin is used in ipsec.conf configurations having | |
1044 | rightsourceip set to %dhcp. | |
1045 | ||
6d6994c6 MW |
1046 | - A new plugin called farp fakes ARP responses for virtual IP addresses |
1047 | handed out to clients from the IKEv2 daemon charon. The plugin lets a | |
89bf11d2 | 1048 | road-warrior act as a client on the local LAN if it uses a virtual IP |
6d6994c6 MW |
1049 | from the responders subnet, e.g. acquired using the DHCP plugin. |
1050 | ||
00c60592 MW |
1051 | - The existing IKEv2 socket implementations have been migrated to the |
1052 | socket-default and the socket-raw plugins. The new socket-dynamic plugin | |
1053 | binds sockets dynamically to ports configured via the left-/rightikeport | |
1054 | ipsec.conf connection parameters. | |
1055 | ||
3e6b50ed MW |
1056 | - The android charon plugin stores received DNS server information as "net.dns" |
1057 | system properties, as used by the Android platform. | |
00c60592 | 1058 | |
d6457833 | 1059 | |
4c68a85a AS |
1060 | strongswan-4.3.6 |
1061 | ---------------- | |
1062 | ||
cdad91de | 1063 | - The IKEv2 daemon supports RFC 3779 IP address block constraints |
e98a4d80 AS |
1064 | carried as a critical X.509v3 extension in the peer certificate. |
1065 | ||
a7155606 AS |
1066 | - The ipsec pool --add|del dns|nbns command manages DNS and NBNS name |
1067 | server entries that are sent via the IKEv1 Mode Config or IKEv2 | |
1068 | Configuration Payload to remote clients. | |
1069 | ||
f721e0fb AS |
1070 | - The Camellia cipher can be used as an IKEv1 encryption algorithm. |
1071 | ||
4c68a85a AS |
1072 | - The IKEv1 and IKEV2 daemons now check certificate path length constraints. |
1073 | ||
909c0c3d MW |
1074 | - The new ipsec.conf conn option "inactivity" closes a CHILD_SA if no traffic |
1075 | was sent or received within the given interval. To close the complete IKE_SA | |
1076 | if its only CHILD_SA was inactive, set the global strongswan.conf option | |
aa9eeb5d MW |
1077 | "charon.inactivity_close_ike" to yes. |
1078 | ||
44e41c4c AS |
1079 | - More detailed IKEv2 EAP payload information in debug output |
1080 | ||
2b2c69e9 | 1081 | - IKEv2 EAP-SIM and EAP-AKA share joint libsimaka library |
44e41c4c | 1082 | |
52fd0ef9 MW |
1083 | - Added required userland changes for proper SHA256 and SHA384/512 in ESP that |
1084 | will be introduced with Linux 2.6.33. The "sha256"/"sha2_256" keyword now | |
1085 | configures the kernel with 128 bit truncation, not the non-standard 96 | |
1086 | bit truncation used by previous releases. To use the old 96 bit truncation | |
1087 | scheme, the new "sha256_96" proposal keyword has been introduced. | |
4c68a85a | 1088 | |
2b2c69e9 MW |
1089 | - Fixed IPComp in tunnel mode, stripping out the duplicated outer header. This |
1090 | change makes IPcomp tunnel mode connections incompatible with previous | |
1091 | releases; disable compression on such tunnels. | |
1092 | ||
6ec949e0 MW |
1093 | - Fixed BEET mode connections on recent kernels by installing SAs with |
1094 | appropriate traffic selectors, based on a patch by Michael Rossberg. | |
1095 | ||
cdad91de MW |
1096 | - Using extensions (such as BEET mode) and crypto algorithms (such as twofish, |
1097 | serpent, sha256_96) allocated in the private use space now require that we | |
1098 | know its meaning, i.e. we are talking to strongSwan. Use the new | |
1099 | "charon.send_vendor_id" option in strongswan.conf to let the remote peer know | |
1100 | this is the case. | |
1101 | ||
aca9f9ab MW |
1102 | - Experimental support for draft-eronen-ipsec-ikev2-eap-auth, where the |
1103 | responder omits public key authentication in favor of a mutual authentication | |
1104 | method. To enable EAP-only authentication, set rightauth=eap on the responder | |
1105 | to rely only on the MSK constructed AUTH payload. This not-yet standardized | |
1106 | extension requires the strongSwan vendor ID introduced above. | |
1107 | ||
0a975307 AS |
1108 | - The IKEv1 daemon ignores the Juniper SRX notification type 40001, thus |
1109 | allowing interoperability. | |

1114 | ||
628f023d AS |
1115 | - The IKEv1 pluto daemon can now use SQL-based address pools to deal out |
1116 | virtual IP addresses as a Mode Config server. The pool capability has been | |
1117 | migrated from charon's sql plugin to a new attr-sql plugin which is loaded | |
b42bfc79 | 1118 | by libstrongswan and which can be used by both daemons either with a SQLite |
628f023d AS |
1119 | or MySQL database and the corresponding plugin. |
1120 | ||
b42bfc79 MW |
1121 | - Plugin names have been streamlined: EAP plugins now have a dash after eap |
1122 | (e.g. eap-sim), as it is used with the --enable-eap-sim ./configure option. | |
1123 | Plugin configuration sections in strongswan.conf now use the same name as the | |
1124 | plugin itself (i.e. with a dash). Make sure to update "load" directives and | |
1125 | the affected plugin sections in existing strongswan.conf files. | |
1126 | ||
d245f5cf AS |
1127 | - The private/public key parsing and encoding has been split up into |
1128 | separate pkcs1, pgp, pem and dnskey plugins. The public key implementation | |
1129 | plugins gmp, gcrypt and openssl can all make use of them. | |
b6b90b68 | 1130 | |
55b045ab MW |
1131 | - The EAP-AKA plugin can use different backends for USIM/quintuplet |
1132 | calculations, very similar to the EAP-SIM plugin. The existing 3GPP2 software | |
1133 | implementation has been migrated to a separate plugin. | |
1134 | ||
d245f5cf | 1135 | - The IKEv2 daemon charon gained basic PGP support. It can use locally installed |
b6b90b68 MW |
1136 | peer certificates and can issue signatures based on RSA private keys. |
1137 | ||
1138 | - The new 'ipsec pki' tool provides a set of commands to maintain a public | |
1139 | key infrastructure. It currently supports operations to create RSA and ECDSA | |
1140 | private/public keys, calculate fingerprints and issue or verify certificates. | |
1141 | ||
1142 | - Charon uses a monotonic time source for statistics and job queueing, behaving | |
1143 | correctly if the system time changes (e.g. when using NTP). | |
1144 | ||
1145 | - In addition to time based rekeying, charon supports IPsec SA lifetimes based | |
1146 | on processed volume or number of packets. They new ipsec.conf paramaters | |
1147 | 'lifetime' (an alias to 'keylife'), 'lifebytes' and 'lifepackets' handle | |
1148 | SA timeouts, while the parameters 'margintime' (an alias to rekeymargin), | |
1149 | 'marginbytes' and 'marginpackets' trigger the rekeying before a SA expires. | |
1150 | The existing parameter 'rekeyfuzz' affects all margins. | |
1151 | ||
85af7a89 MW |
1152 | - If no CA/Gateway certificate is specified in the NetworkManager plugin, |
1153 | charon uses a set of trusted root certificates preinstalled by distributions. | |
1154 | The directory containing CA certificates can be specified using the | |
1155 | --with-nm-ca-dir=path configure option. | |
1156 | ||
b80fa9ca | 1157 | - Fixed the encoding of the Email relative distinguished name in left|rightid |
509f70c1 | 1158 | statements. |
b80fa9ca | 1159 | |
509f70c1 AS |
1160 | - Fixed the broken parsing of PKCS#7 wrapped certificates by the pluto daemon. |
1161 | ||
1162 | - Fixed smartcard-based authentication in the pluto daemon which was broken by | |
1163 | the ECDSA support introduced with the 4.3.2 release. | |
1164 | ||
cea4bd8f AS |
1165 | - A patch contributed by Heiko Hund fixes mixed IPv6 in IPv4 and vice versa |
1166 | tunnels established with the IKEv1 pluto daemon. | |
1167 | ||
509f70c1 AS |
1168 | - The pluto daemon now uses the libstrongswan x509 plugin for certificates and |
1169 | CRls and the struct id type was replaced by identification_t used by charon | |
1170 | and the libstrongswan library. | |
18060241 | 1171 | |
85af7a89 | 1172 | |
430dd08a AS |
1173 | strongswan-4.3.4 |
1174 | ---------------- | |
1175 | ||
1176 | - IKEv2 charon daemon ported to FreeBSD and Mac OS X. Installation details can | |
1177 | be found on wiki.strongswan.org. | |
1178 | ||
1179 | - ipsec statusall shows the number of bytes transmitted and received over | |
1180 | ESP connections configured by the IKEv2 charon daemon. | |
1181 | ||
1182 | - The IKEv2 charon daemon supports include files in ipsec.secrets. | |
1183 | ||
1184 | ||
1c7f456a AS |
1185 | strongswan-4.3.3 |
1186 | ---------------- | |
1187 | ||
aa74d705 AS |
1188 | - The configuration option --enable-integrity-test plus the strongswan.conf |
1189 | option libstrongswan.integrity_test = yes activate integrity tests | |
1190 | of the IKE daemons charon and pluto, libstrongswan and all loaded | |
1191 | plugins. Thus dynamic library misconfigurations and non-malicious file | |
1192 | manipulations can be reliably detected. | |
1193 | ||
1c7f456a AS |
1194 | - The new default setting libstrongswan.ecp_x_coordinate_only=yes allows |
1195 | IKEv1 interoperability with MS Windows using the ECP DH groups 19 and 20. | |
1196 | ||
1197 | - The IKEv1 pluto daemon now supports the AES-CCM and AES-GCM ESP | |
1198 | authenticated encryption algorithms. | |
1199 | ||
aa74d705 AS |
1200 | - The IKEv1 pluto daemon now supports V4 OpenPGP keys. |
1201 | ||
1202 | - The RDN parser vulnerability discovered by Orange Labs research team | |
1203 | was not completely fixed in version 4.3.2. Some more modifications | |
1204 | had to be applied to the asn1_length() function to make it robust. | |
1205 | ||
1c7f456a | 1206 | |
80c0710c MW |
1207 | strongswan-4.3.2 |
1208 | ---------------- | |
1209 | ||
1210 | - The new gcrypt plugin provides symmetric cipher, hasher, RNG, Diffie-Hellman | |
1211 | and RSA crypto primitives using the LGPL licensed GNU gcrypt library. | |
1212 | ||
1213 | - libstrongswan features an integrated crypto selftest framework for registered | |
1214 | algorithms. The test-vector plugin provides a first set of test vectors and | |
1215 | allows pluto and charon to rely on tested crypto algorithms. | |
1216 | ||
b32af120 AS |
1217 | - pluto can now use all libstrongswan plugins with the exception of x509 and xcbc. |
1218 | Thanks to the openssl plugin, the ECP Diffie-Hellman groups 19, 20, 21, 25, and | |
1219 | 26 as well as ECDSA-256, ECDSA-384, and ECDSA-521 authentication can be used | |
1220 | with IKEv1. | |
126f2130 AS |
1221 | |
1222 | - Applying their fuzzing tool, the Orange Labs vulnerability research team found | |
1223 | another two DoS vulnerabilities, one in the rather old ASN.1 parser of Relative | |
1224 | Distinguished Names (RDNs) and a second one in the conversion of ASN.1 UTCTIME | |
1225 | and GENERALIZEDTIME strings to a time_t value. | |
b6b90b68 | 1226 | |
b32af120 | 1227 | |
3bf7c249 MW |
1228 | strongswan-4.3.1 |
1229 | ---------------- | |
1230 | ||
1231 | - The nm plugin now passes DNS/NBNS server information to NetworkManager, | |
09dbca9f | 1232 | allowing a gateway administrator to set DNS/NBNS configuration on clients |
3bf7c249 MW |
1233 | dynamically. |
1234 | ||
09dbca9f MW |
1235 | - The nm plugin also accepts CA certificates for gateway authentication. If |
1236 | a CA certificate is configured, strongSwan uses the entered gateway address | |
1237 | as its idenitity, requiring the gateways certificate to contain the same as | |
1238 | subjectAltName. This allows a gateway administrator to deploy the same | |
1239 | certificates to Windows 7 and NetworkManager clients. | |
047b2e42 | 1240 | |
050cc582 AS |
1241 | - The command ipsec purgeike deletes IKEv2 SAs that don't have a CHILD SA. |
1242 | The command ipsec down <conn>{n} deletes CHILD SA instance n of connection | |
1243 | <conn> whereas ipsec down <conn>{*} deletes all CHILD SA instances. | |
1244 | The command ipsec down <conn>[n] deletes IKE SA instance n of connection | |
1245 | <conn> plus dependent CHILD SAs whereas ipsec down <conn>[*] deletes all | |
1246 | IKE SA instances of connection <conn>. | |
1247 | ||
09dbca9f | 1248 | - Fixed a regression introduced in 4.3.0 where EAP authentication calculated |
047b2e42 MW |
1249 | the AUTH payload incorrectly. Further, the EAP-MSCHAPv2 MSK key derivation |
1250 | has been updated to be compatible with the Windows 7 Release Candidate. | |
1251 | ||
1252 | - Refactored installation of triggering policies. Routed policies are handled | |
1253 | outside of IKE_SAs to keep them installed in any case. A tunnel gets | |
1254 | established only once, even if initiation is delayed due network outages. | |
1255 | ||
050cc582 AS |
1256 | - Improved the handling of multiple acquire signals triggered by the kernel. |
1257 | ||
1258 | - Fixed two DoS vulnerabilities in the charon daemon that were discovered by | |
1259 | fuzzing techniques: 1) Sending a malformed IKE_SA_INIT request leaved an | |
1260 | incomplete state which caused a null pointer dereference if a subsequent | |
1261 | CREATE_CHILD_SA request was sent. 2) Sending an IKE_AUTH request with either | |
1262 | a missing TSi or TSr payload caused a null pointer derefence because the | |
b6b90b68 | 1263 | checks for TSi and TSr were interchanged. The IKEv2 fuzzer used was |
f3bb1bd0 | 1264 | developed by the Orange Labs vulnerability research team. The tool was |
050cc582 AS |
1265 | initially written by Gabriel Campana and is now maintained by Laurent Butti. |
1266 | ||
047b2e42 MW |
1267 | - Added support for AES counter mode in ESP in IKEv2 using the proposal |
1268 | keywords aes128ctr, aes192ctr and aes256ctr. | |
1269 | ||
d44fd821 | 1270 | - Further progress in refactoring pluto: Use of the curl and ldap plugins |
050cc582 AS |
1271 | for fetching crls and OCSP. Use of the random plugin to get keying material |
1272 | from /dev/random or /dev/urandom. Use of the openssl plugin as an alternative | |
d44fd821 | 1273 | to the aes, des, sha1, sha2, and md5 plugins. The blowfish, twofish, and |
050cc582 | 1274 | serpent encryption plugins are now optional and are not enabled by default. |
d44fd821 AS |
1275 | |

247e665a AS |
1277 | strongswan-4.3.0 |
1278 | ---------------- | |
1279 | ||
81fc8e5f MW |
1280 | - Support for the IKEv2 Multiple Authentication Exchanges extension (RFC4739). |
1281 | Initiators and responders can use several authentication rounds (e.g. RSA | |
1282 | followed by EAP) to authenticate. The new ipsec.conf leftauth/rightauth and | |
1283 | leftauth2/rightauth2 parameters define own authentication rounds or setup | |
1284 | constraints for the remote peer. See the ipsec.conf man page for more detials. | |
1285 | ||
1286 | - If glibc printf hooks (register_printf_function) are not available, | |
1287 | strongSwan can use the vstr string library to run on non-glibc systems. | |
1288 | ||
558c89e7 AS |
1289 | - The IKEv2 charon daemon can now configure the ESP CAMELLIA-CBC cipher |
1290 | (esp=camellia128|192|256). | |
247e665a | 1291 | |
558c89e7 AS |
1292 | - Refactored the pluto and scepclient code to use basic functions (memory |
1293 | allocation, leak detective, chunk handling, printf_hooks, strongswan.conf | |
1294 | attributes, ASN.1 parser, etc.) from the libstrongswan library. | |
b752f873 | 1295 | |
558c89e7 AS |
1296 | - Up to two DNS and WINS servers to be sent via IKEv1 ModeConfig can be |
1297 | configured in the pluto section of strongswan.conf. | |

1300 | strongswan-4.2.14 |
1301 | ----------------- | |
1302 | ||
22180558 | 1303 | - The new server-side EAP RADIUS plugin (--enable-eap-radius) |
f3bb1bd0 | 1304 | relays EAP messages to and from a RADIUS server. Successfully |
22180558 AS |
1305 | tested with with a freeradius server using EAP-MD5 and EAP-SIM. |
1306 | ||
79b27294 AS |
1307 | - A vulnerability in the Dead Peer Detection (RFC 3706) code was found by |
1308 | Gerd v. Egidy <gerd.von.egidy@intra2net.com> of Intra2net AG affecting | |
1309 | all Openswan and strongSwan releases. A malicious (or expired ISAKMP) | |
1310 | R_U_THERE or R_U_THERE_ACK Dead Peer Detection packet can cause the | |
1311 | pluto IKE daemon to crash and restart. No authentication or encryption | |
1312 | is required to trigger this bug. One spoofed UDP packet can cause the | |
1313 | pluto IKE daemon to restart and be unresponsive for a few seconds while | |
1314 | restarting. This DPD null state vulnerability has been officially | |
1315 | registered as CVE-2009-0790 and is fixed by this release. | |
1316 | ||
22180558 AS |
1317 | - ASN.1 to time_t conversion caused a time wrap-around for |
1318 | dates after Jan 18 03:14:07 UTC 2038 on 32-bit platforms. | |
1319 | As a workaround such dates are set to the maximum representable | |
1320 | time, i.e. Jan 19 03:14:07 UTC 2038. | |
1321 | ||
1322 | - Distinguished Names containing wildcards (*) are not sent in the | |
b6b90b68 | 1323 | IDr payload anymore. |
623bca40 AS |
1324 | |
1325 | ||
076e7853 AS |
1326 | strongswan-4.2.13 |
1327 | ----------------- | |
1328 | ||
1329 | - Fixed a use-after-free bug in the DPD timeout section of the | |
1330 | IKEv1 pluto daemon which sporadically caused a segfault. | |
1331 | ||
f3bb1bd0 | 1332 | - Fixed a crash in the IKEv2 charon daemon occurring with |
b6b90b68 | 1333 | mixed RAM-based and SQL-based virtual IP address pools. |
076e7853 | 1334 | |
f15483ef AS |
1335 | - Fixed ASN.1 parsing of algorithmIdentifier objects where the |
1336 | parameters field is optional. | |
1337 | ||
03991bc1 MW |
1338 | - Ported nm plugin to NetworkManager 7.1. |
1339 | ||
076e7853 | 1340 | |
bfde75ee | 1341 | strongswan-4.2.12 |
076e7853 | 1342 | ----------------- |
bfde75ee AS |
1343 | |
1344 | - Support of the EAP-MSCHAPv2 protocol enabled by the option | |
1345 | --enable-eap-mschapv2. Requires the MD4 hash algorithm enabled | |
1346 | either by --enable-md4 or --enable-openssl. | |
1347 | ||
1348 | - Assignment of up to two DNS and up to two WINS servers to peers via | |
b6b90b68 | 1349 | the IKEv2 Configuration Payload (CP). The IPv4 or IPv6 nameserver |
bfde75ee AS |
1350 | addresses are defined in strongswan.conf. |
1351 | ||
1352 | - The strongSwan applet for the Gnome NetworkManager is now built and | |
1353 | distributed as a separate tarball under the name NetworkManager-strongswan. | |
1354 | ||
b6b90b68 | 1355 | |
0519ca90 AS |
1356 | strongswan-4.2.11 |
1357 | ----------------- | |
1358 | ||
ae1ae574 AS |
1359 | - Fixed ESP NULL encryption broken by the refactoring of keymat.c. |
1360 | Also introduced proper initialization and disposal of keying material. | |
1361 | ||
1362 | - Fixed the missing listing of connection definitions in ipsec statusall | |
1363 | broken by an unfortunate local variable overload. | |
0519ca90 AS |
1364 | |
1365 | ||
4856241c MW |
1366 | strongswan-4.2.10 |
1367 | ----------------- | |
1368 | ||
1369 | - Several performance improvements to handle thousands of tunnels with almost | |
1370 | linear upscaling. All relevant data structures have been replaced by faster | |
1371 | counterparts with better lookup times. | |
1372 | ||
1373 | - Better parallelization to run charon on multiple cores. Due to improved | |
1374 | ressource locking and other optimizations the daemon can take full | |
1375 | advantage of 16 or even more cores. | |
1376 | ||
1377 | - The load-tester plugin can use a NULL Diffie-Hellman group and simulate | |
1378 | unique identities and certificates by signing peer certificates using a CA | |
1379 | on the fly. | |
1380 | ||
1381 | - The redesigned stroke in-memory IP pool handles leases. The "ipsec leases" | |
1382 | command queries assigned leases. | |
1383 | ||
1384 | - Added support for smartcards in charon by using the ENGINE API provided by | |
1385 | OpenSSL, based on patches by Michael Roßberg. | |
1386 | ||
1387 | - The Padlock plugin supports the hardware RNG found on VIA CPUs to provide a | |
1388 | reliable source of randomness. | |
1389 | ||
73937bd8 MW |
1390 | strongswan-4.2.9 |
1391 | ---------------- | |
1392 | ||
509e07c5 AS |
1393 | - Flexible configuration of logging subsystem allowing to log to multiple |
1394 | syslog facilities or to files using fine-grained log levels for each target. | |
73937bd8 MW |
1395 | |
1396 | - Load testing plugin to do stress testing of the IKEv2 daemon against self | |
1397 | or another host. Found and fixed issues during tests in the multi-threaded | |
1398 | use of the OpenSSL plugin. | |
1399 | ||
1400 | - Added profiling code to synchronization primitives to find bottlenecks if | |
7bdc931e | 1401 | running on multiple cores. Found and fixed an issue where parts of the |
73937bd8 MW |
1402 | Diffie-Hellman calculation acquired an exclusive lock. This greatly improves |
1403 | parallelization to multiple cores. | |
1404 | ||
509e07c5 AS |
1405 | - updown script invocation has been separated into a plugin of its own to |
1406 | further slim down the daemon core. | |
73937bd8 | 1407 | |
509e07c5 | 1408 | - Separated IKE_SA/CHILD_SA key derivation process into a closed system, |
7bdc931e | 1409 | allowing future implementations to use a secured environment in e.g. kernel |
73937bd8 MW |
1410 | memory or hardware. |
1411 | ||
509e07c5 AS |
1412 | - The kernel interface of charon has been modularized. XFRM NETLINK (default) |
1413 | and PFKEY (--enable-kernel-pfkey) interface plugins for the native IPsec | |
1414 | stack of the Linux 2.6 kernel as well as a PFKEY interface for the KLIPS | |
1415 | IPsec stack (--enable-kernel-klips) are provided. | |
1416 | ||
1417 | - Basic Mobile IPv6 support has been introduced, securing Binding Update | |
1418 | messages as well as tunneled traffic between Mobile Node and Home Agent. | |
1419 | The installpolicy=no option allows peaceful cooperation with a dominant | |
1420 | mip6d daemon and the new type=transport_proxy implements the special MIPv6 | |
1421 | IPsec transport proxy mode where the IKEv2 daemon uses the Care-of-Address | |
f3bb1bd0 | 1422 | but the IPsec SA is set up for the Home Address. |
7bdc931e | 1423 | |
4dc0dce8 AS |
1424 | - Implemented migration of Mobile IPv6 connections using the KMADDRESS |
1425 | field contained in XFRM_MSG_MIGRATE messages sent by the mip6d daemon | |
1426 | via the Linux 2.6.28 (or appropriately patched) kernel. | |

1429 | strongswan-4.2.8 |
1430 | ---------------- | |
1431 | ||
5dadb16e | 1432 | - IKEv2 charon daemon supports authentication based on raw public keys |
e39b271b AS |
1433 | stored in the SQL database backend. The ipsec listpubkeys command |
1434 | lists the available raw public keys via the stroke interface. | |
1435 | ||
4f0241e6 MW |
1436 | - Several MOBIKE improvements: Detect changes in NAT mappings in DPD exchanges, |
1437 | handle events if kernel detects NAT mapping changes in UDP-encapsulated | |
1438 | ESP packets (requires kernel patch), reuse old addesses in MOBIKE updates as | |
1439 | long as possible and other fixes. | |
1440 | ||
5dadb16e AS |
1441 | - Fixed a bug in addr_in_subnet() which caused insertion of wrong source |
1442 | routes for destination subnets having netwmasks not being a multiple of 8 bits. | |
1443 | Thanks go to Wolfgang Steudel, TU Ilmenau for reporting this bug. | |

1446 | strongswan-4.2.7 |
1447 | ---------------- | |
1448 | ||
b37cda82 AS |
1449 | - Fixed a Denial-of-Service vulnerability where an IKE_SA_INIT message with |
1450 | a KE payload containing zeroes only can cause a crash of the IKEv2 charon | |
1451 | daemon due to a NULL pointer returned by the mpz_export() function of the | |
1452 | GNU Multiprecision Library (GMP). Thanks go to Mu Dynamics Research Labs | |
b6b90b68 | 1453 | for making us aware of this problem. |
b37cda82 | 1454 | |
b6b90b68 | 1455 | - The new agent plugin provides a private key implementation on top of an |
e376d75f MW |
1456 | ssh-agent. |
1457 | ||
1458 | - The NetworkManager plugin has been extended to support certificate client | |
b1f47854 | 1459 | authentication using RSA keys loaded from a file or using ssh-agent. |
e376d75f MW |
1460 | |
1461 | - Daemon capability dropping has been ported to libcap and must be enabled | |
1462 | explicitly --with-capabilities=libcap. Future version will support the | |
1463 | newer libcap2 library. | |
1464 | ||
b37cda82 AS |

1473 | clients in a simple way. It features X509 based gateway authentication | |
1474 | and EAP client authentication, tunnel setup/teardown and storing passwords | |
1475 | in the Gnome Keyring. | |
1476 | ||
1477 | - A new EAP-GTC plugin implements draft-sheffer-ikev2-gtc-00.txt and allows | |
1478 | username/password authentication against any PAM service on the gateway. | |
b6b90b68 | 1479 | The new EAP method interacts nicely with the NetworkManager plugin and allows |
609166f4 MW |
1480 | client authentication against e.g. LDAP. |
1481 | ||
1482 | - Improved support for the EAP-Identity method. The new ipsec.conf eap_identity | |
1483 | parameter defines an additional identity to pass to the server in EAP | |
1484 | authentication. | |
1485 | ||
9f9d6ece AS |
1486 | - The "ipsec statusall" command now lists CA restrictions, EAP |
1487 | authentication types and EAP identities. | |
1488 | ||
1489 | - Fixed two multithreading deadlocks occurring when starting up | |
1490 | several hundred tunnels concurrently. | |
1491 | ||
1492 | - Fixed the --enable-integrity-test configure option which | |
1493 | computes a SHA-1 checksum over the libstrongswan library. | |
1494 | ||
1495 | ||
174216c7 AS |
1496 | strongswan-4.2.5 |
1497 | ---------------- | |
1498 | ||
b6b90b68 | 1499 | - Consistent logging of IKE and CHILD SAs at the audit (AUD) level. |
8124e491 AS |
1500 | |
1501 | - Improved the performance of the SQL-based virtual IP address pool | |
1502 | by introducing an additional addresses table. The leases table | |
1503 | storing only history information has become optional and can be | |
1504 | disabled by setting charon.plugins.sql.lease_history = no in | |
1505 | strongswan.conf. | |
1506 | ||
eb0cc338 | 1507 | - The XFRM_STATE_AF_UNSPEC flag added to xfrm.h allows IPv4-over-IPv6 |
de5f70e7 | 1508 | and IPv6-over-IPv4 tunnels with the 2.6.26 and later Linux kernels. |
eb0cc338 | 1509 | |
174216c7 AS |
1510 | - management of different virtual IP pools for different |
1511 | network interfaces have become possible. | |
1512 | ||
b6b90b68 | 1513 | - fixed a bug which prevented the assignment of more than 256 |
174216c7 AS |
1514 | virtual IP addresses from a pool managed by an sql database. |
1515 | ||
8124e491 AS |
1516 | - fixed a bug which did not delete own IPCOMP SAs in the kernel. |
1517 | ||
b6b90b68 | 1518 | |
179dd12c AS |
1519 | strongswan-4.2.4 |
1520 | ---------------- | |
1521 | ||
9de95037 AS |
1522 | - Added statistics functions to ipsec pool --status and ipsec pool --leases |
1523 | and input validation checks to various ipsec pool commands. | |
179dd12c | 1524 | |
73a8eed3 | 1525 | - ipsec statusall now lists all loaded charon plugins and displays |
9de95037 | 1526 | the negotiated IKEv2 cipher suite proposals. |
73a8eed3 AS |
1527 | |
1528 | - The openssl plugin supports the elliptic curve Diffie-Hellman groups | |
1529 | 19, 20, 21, 25, and 26. | |
1530 | ||
1531 | - The openssl plugin supports ECDSA authentication using elliptic curve | |
1532 | X.509 certificates. | |
1533 | ||
1534 | - Fixed a bug in stroke which caused multiple charon threads to close | |
1535 | the file descriptors during packet transfers over the stroke socket. | |
b6b90b68 | 1536 | |
e0bb4dbb AS |
1537 | - ESP sequence numbers are now migrated in IPsec SA updates handled by |
1538 | MOBIKE. Works only with Linux kernels >= 2.6.17. | |
1539 | ||
179dd12c | 1540 | |
83d9e870 AS |
1541 | strongswan-4.2.3 |
1542 | ---------------- | |
1543 | ||
b6b90b68 | 1544 | - Fixed the strongswan.conf path configuration problem that occurred when |
83d9e870 AS |
1545 | --sysconfig was not set explicitly in ./configure. |
1546 | ||
1547 | - Fixed a number of minor bugs that where discovered during the 4th | |
1548 | IKEv2 interoperability workshop in San Antonio, TX. | |
1549 | ||
1550 | ||
7f491111 MW |
1551 | strongswan-4.2.2 |
1552 | ---------------- | |
1553 | ||
a57cd446 AS |
1554 | - Plugins for libstrongswan and charon can optionally be loaded according |
1555 | to a configuration in strongswan.conf. Most components provide a | |
7f491111 | 1556 | "load = " option followed by a space separated list of plugins to load. |
a57cd446 AS |
1557 | This allows e.g. the fallback from a hardware crypto accelerator to |
1558 | to software-based crypto plugins. | |
7f491111 MW |
1559 | |
1560 | - Charons SQL plugin has been extended by a virtual IP address pool. | |
a57cd446 AS |
1561 | Configurations with a rightsourceip=%poolname setting query a SQLite or |
1562 | MySQL database for leases. The "ipsec pool" command helps in administrating | |
1563 | the pool database. See ipsec pool --help for the available options | |
1564 | ||
1565 | - The Authenticated Encryption Algorithms AES-CCM-8/12/16 and AES-GCM-8/12/16 | |
b6b90b68 | 1566 | for ESP are now supported starting with the Linux 2.6.25 kernel. The |
a57cd446 AS |
1567 | syntax is e.g. esp=aes128ccm12 or esp=aes256gcm16. |
1568 | ||
7f491111 | 1569 | |
5c5d67d6 AS |
1570 | strongswan-4.2.1 |
1571 | ---------------- | |
1572 | ||
c306dfb1 | 1573 | - Support for "Hash and URL" encoded certificate payloads has been implemented |
b1f8fc0c TB |
1574 | in the IKEv2 daemon charon. Using the "certuribase" option of a CA section |
1575 | allows to assign a base URL to all certificates issued by the specified CA. | |
1576 | The final URL is then built by concatenating that base and the hex encoded | |
1577 | SHA1 hash of the DER encoded certificate. Note that this feature is disabled | |
1578 | by default and must be enabled using the option "charon.hash_and_url". | |
5c5d67d6 | 1579 | |
58caabf7 MW |
1580 | - The IKEv2 daemon charon now supports the "uniqueids" option to close multiple |
1581 | IKE_SAs with the same peer. The option value "keep" prefers existing | |
1582 | connection setups over new ones, where the value "replace" replaces existing | |
1583 | connections. | |
b6b90b68 | 1584 | |
f3bb1bd0 | 1585 | - The crypto factory in libstrongswan additionally supports random number |
58caabf7 | 1586 | generators, plugins may provide other sources of randomness. The default |
c306dfb1 | 1587 | plugin reads raw random data from /dev/(u)random. |
58caabf7 | 1588 | |
b6b90b68 | 1589 | - Extended the credential framework by a caching option to allow plugins |
58caabf7 | 1590 | persistent caching of fetched credentials. The "cachecrl" option has been |
c306dfb1 | 1591 | re-implemented. |
58caabf7 MW |
1592 | |
1593 | - The new trustchain verification introduced in 4.2.0 has been parallelized. | |
1594 | Threads fetching CRL or OCSP information no longer block other threads. | |
5c5d67d6 | 1595 | |
58caabf7 MW |
1596 | - A new IKEv2 configuration attribute framework has been introduced allowing |
1597 | plugins to provide virtual IP addresses, and in the future, other | |
1598 | configuration attribute services (e.g. DNS/WINS servers). | |
5c5d67d6 | 1599 | |
466abb49 | 1600 | - The stroke plugin has been extended to provide virtual IP addresses from |
58caabf7 MW |
1601 | a pool defined in ipsec.conf. The "rightsourceip" parameter now accepts |
1602 | address pools in CIDR notation (e.g. 10.1.1.0/24). The parameter also accepts | |
1603 | the value "%poolname", where "poolname" identifies a pool provided by a | |
466abb49 | 1604 | separate plugin. |
58caabf7 | 1605 | |
c306dfb1 | 1606 | - Fixed compilation on uClibc and a couple of other minor bugs. |
58caabf7 | 1607 | |
c306dfb1 | 1608 | - Set DPD defaults in ipsec starter to dpd_delay=30s and dpd_timeout=150s. |
466abb49 AS |
1609 | |
1610 | - The IKEv1 pluto daemon now supports the ESP encryption algorithm CAMELLIA | |
c306dfb1 | 1611 | with key lengths of 128, 192, and 256 bits, as well as the authentication |
466abb49 AS |
1612 | algorithm AES_XCBC_MAC. Configuration example: esp=camellia192-aesxcbc. |
1613 | ||
5c5d67d6 | 1614 | |
a11ea97d AS |
1615 | strongswan-4.2.0 |
1616 | ---------------- | |
1617 | ||
16f5dacd MW |
1618 | - libstrongswan has been modularized to attach crypto algorithms, |
1619 | credential implementations (keys, certificates) and fetchers dynamically | |
1620 | through plugins. Existing code has been ported to plugins: | |
1621 | - RSA/Diffie-Hellman implementation using the GNU Multi Precision library | |
1622 | - X509 certificate system supporting CRLs, OCSP and attribute certificates | |
1623 | - Multiple plugins providing crypto algorithms in software | |
1624 | - CURL and OpenLDAP fetcher | |
a11ea97d | 1625 | |
16f5dacd MW |
1626 | - libstrongswan gained a relational database API which uses pluggable database |
1627 | providers. Plugins for MySQL and SQLite are available. | |
1628 | ||
1629 | - The IKEv2 keying daemon charon is more extensible. Generic plugins may provide | |
1630 | connection configuration, credentials and EAP methods or control the daemon. | |
1631 | Existing code has been ported to plugins: | |
1632 | - EAP-AKA, EAP-SIM, EAP-MD5 and EAP-Identity | |
1633 | - stroke configuration, credential and control (compatible to pluto) | |
1634 | - XML bases management protocol to control and query the daemon | |
1635 | The following new plugins are available: | |
1636 | - An experimental SQL configuration, credential and logging plugin on | |
1637 | top of either MySQL or SQLite | |
1638 | - A unit testing plugin to run tests at daemon startup | |
1639 | ||
1640 | - The authentication and credential framework in charon has been heavily | |
1641 | refactored to support modular credential providers, proper | |
1642 | CERTREQ/CERT payload exchanges and extensible authorization rules. | |
1643 | ||
b6b90b68 | 1644 | - The framework of strongSwan Manager has envolved to the web application |
16f5dacd MW |
1645 | framework libfast (FastCGI Application Server w/ Templates) and is usable |
1646 | by other applications. | |
b6b90b68 | 1647 | |

1649 | strongswan-4.1.11 |
1650 | ----------------- | |
fb6d76cd | 1651 | |
a561f74d AS |
1652 | - IKE rekeying in NAT situations did not inherit the NAT conditions |
1653 | to the rekeyed IKE_SA so that the UDP encapsulation was lost with | |
1654 | the next CHILD_SA rekeying. | |
1655 | ||
1656 | - Wrong type definition of the next_payload variable in id_payload.c | |
b6b90b68 | 1657 | caused an INVALID_SYNTAX error on PowerPC platforms. |
fb6d76cd | 1658 | |
e6b50b3f AS |
1659 | - Implemented IKEv2 EAP-SIM server and client test modules that use |
1660 | triplets stored in a file. For details on the configuration see | |
1661 | the scenario 'ikev2/rw-eap-sim-rsa'. | |
1662 | ||
fb6d76cd | 1663 | |
83e0d841 AS |
1664 | strongswan-4.1.10 |
1665 | ----------------- | |
1666 | ||
1667 | - Fixed error in the ordering of the certinfo_t records in the ocsp cache that | |
b6b90b68 | 1668 | caused multiple entries of the same serial number to be created. |
83e0d841 | 1669 | |
fdc7c943 MW |
1670 | - Implementation of a simple EAP-MD5 module which provides CHAP |
1671 | authentication. This may be interesting in conjunction with certificate | |
1672 | based server authentication, as weak passwords can't be brute forced | |
1673 | (in contradiction to traditional IKEv2 PSK). | |
1674 | ||
1675 | - A complete software based implementation of EAP-AKA, using algorithms | |
1676 | specified in 3GPP2 (S.S0055). This implementation does not use an USIM, | |
1677 | but reads the secrets from ipsec.secrets. Make sure to read eap_aka.h | |
1678 | before using it. | |
1679 | ||
1680 | - Support for vendor specific EAP methods using Expanded EAP types. The | |
b6b90b68 | 1681 | interface to EAP modules has been slightly changed, so make sure to |
fdc7c943 | 1682 | check the changes if you're already rolling your own modules. |
83e0d841 | 1683 | |
fb6d76cd | 1684 | |
5076770c AS |
1685 | strongswan-4.1.9 |
1686 | ---------------- | |
1687 | ||
800b3356 AS |
1688 | - The default _updown script now dynamically inserts and removes ip6tables |
1689 | firewall rules if leftfirewall=yes is set in IPv6 connections. New IPv6 | |
1690 | net-net and roadwarrior (PSK/RSA) scenarios for both IKEv1 and IKEV2 were | |
1691 | added. | |
5076770c | 1692 | |
6f274c2a MW |
1693 | - Implemented RFC4478 repeated authentication to force EAP/Virtual-IP clients |
1694 | to reestablish an IKE_SA within a given timeframe. | |
1695 | ||
1696 | - strongSwan Manager supports configuration listing, initiation and termination | |
1697 | of IKE and CHILD_SAs. | |
1698 | ||
1699 | - Fixes and improvements to multithreading code. | |
1700 | ||
8b678ad4 | 1701 | - IKEv2 plugins have been renamed to libcharon-* to avoid naming conflicts. |
b6b90b68 | 1702 | Make sure to remove the old plugins in $libexecdir/ipsec, otherwise they get |
8b678ad4 | 1703 | loaded twice. |
5076770c | 1704 | |
83e0d841 | 1705 | |
b82e8231 AS |
1706 | strongswan-4.1.8 |
1707 | ---------------- | |
1708 | ||
5076770c | 1709 | - Removed recursive pthread mutexes since uClibc doesn't support them. |
b82e8231 AS |
1710 | |
1711 | ||
a4a3632c AS |
1712 | strongswan-4.1.7 |
1713 | ---------------- | |
1714 | ||
1715 | - In NAT traversal situations and multiple queued Quick Modes, | |
1716 | those pending connections inserted by auto=start after the | |
1717 | port floating from 500 to 4500 were erronously deleted. | |
1718 | ||
6e193274 | 1719 | - Added a "forceencaps" connection parameter to enforce UDP encapsulation |
078b6008 | 1720 | to surmount restrictive firewalls. NAT detection payloads are faked to |
6e193274 MW |
1721 | simulate a NAT situation and trick the other peer into NAT mode (IKEv2 only). |
1722 | ||
1723 | - Preview of strongSwan Manager, a web based configuration and monitoring | |
1724 | application. It uses a new XML control interface to query the IKEv2 daemon | |
64d24679 | 1725 | (see http://wiki.strongswan.org/wiki/Manager). |
6e193274 MW |
1726 | |
1727 | - Experimental SQLite configuration backend which will provide the configuration | |
1728 | interface for strongSwan Manager in future releases. | |
1729 | ||
1730 | - Further improvements to MOBIKE support. | |
1731 | ||
a4a3632c | 1732 | |
3dcf9dbd AS |
1733 | strongswan-4.1.6 |
1734 | ---------------- | |
1735 | ||
3eac4dfd AS |
1736 | - Since some third party IKEv2 implementations run into |
1737 | problems with strongSwan announcing MOBIKE capability per | |
1738 | default, MOBIKE can be disabled on a per-connection-basis | |
1739 | using the mobike=no option. Whereas mobike=no disables the | |
1740 | sending of the MOBIKE_SUPPORTED notification and the floating | |
1741 | to UDP port 4500 with the IKE_AUTH request even if no NAT | |
1742 | situation has been detected, strongSwan will still support | |
1743 | MOBIKE acting as a responder. | |
1744 | ||
1745 | - the default ipsec routing table plus its corresponding priority | |
1746 | used for inserting source routes has been changed from 100 to 220. | |
1747 | It can be configured using the --with-ipsec-routing-table and | |
b6b90b68 MW |
1748 | --with-ipsec-routing-table-prio options. |
1749 | ||
bdc0b55b AS |
1750 | - the --enable-integrity-test configure option tests the |
1751 | integrity of the libstrongswan crypto code during the charon | |
1752 | startup. | |
b6b90b68 | 1753 | |
3eac4dfd AS |
1754 | - the --disable-xauth-vid configure option disables the sending |
1755 | of the XAUTH vendor ID. This can be used as a workaround when | |
1756 | interoperating with some Windows VPN clients that get into | |
1757 | trouble upon reception of an XAUTH VID without eXtended | |
1758 | AUTHentication having been configured. | |
b6b90b68 | 1759 | |
f872f9d1 AS |
1760 | - ipsec stroke now supports the rereadsecrets, rereadaacerts, |
1761 | rereadacerts, and listacerts options. | |
3dcf9dbd AS |
1762 | |
1763 | ||
7ad634a2 AS |
1764 | strongswan-4.1.5 |
1765 | ---------------- | |
1766 | ||
1767 | - If a DNS lookup failure occurs when resolving right=%<FQDN> | |
1768 | or right=<FQDN> combined with rightallowany=yes then the | |
1769 | connection is not updated by ipsec starter thus preventing | |
1770 | the disruption of an active IPsec connection. Only if the DNS | |
1771 | lookup successfully returns with a changed IP address the | |
1772 | corresponding connection definition is updated. | |
1773 | ||
8f5b363c MW |
1774 | - Routes installed by the keying daemons are now in a separate |
1775 | routing table with the ID 100 to avoid conflicts with the main | |
1776 | table. Route lookup for IKEv2 traffic is done in userspace to ignore | |
1777 | routes installed for IPsec, as IKE traffic shouldn't get encapsulated. | |
1778 | ||
7ad634a2 | 1779 | |
e93c68ba AS |
1780 | strongswan-4.1.4 |
1781 | ---------------- | |
1782 | ||
1783 | - The pluto IKEv1 daemon now exhibits the same behaviour as its | |
1784 | IKEv2 companion charon by inserting an explicit route via the | |
1785 | _updown script only if a sourceip exists. This is admissible | |
1786 | since routing through the IPsec tunnel is handled automatically | |
b7af55ac AS |
1787 | by NETKEY's IPsec policies. As a consequence the left|rightnexthop |
1788 | parameter is not required any more. | |
078ce348 AS |
1789 | |
1790 | - The new IKEv1 parameter right|leftallowany parameters helps to handle | |
1791 | the case where both peers possess dynamic IP addresses that are | |
1792 | usually resolved using DynDNS or a similar service. The configuration | |
1793 | ||
1794 | right=peer.foo.bar | |
1795 | rightallowany=yes | |
1796 | ||
1797 | can be used by the initiator to start up a connection to a peer | |
1798 | by resolving peer.foo.bar into the currently allocated IP address. | |
1799 | Thanks to the rightallowany flag the connection behaves later on | |
1800 | as | |
1801 | ||
1802 | right=%any | |
1803 | ||
1804 | so that the peer can rekey the connection as an initiator when his | |
1fbdab85 AS |
1805 | IP address changes. An alternative notation is |
1806 | ||
1807 | right=%peer.foo.bar | |
1808 | ||
1809 | which will implicitly set rightallowany=yes. | |
1810 | ||
1811 | - ipsec starter now fails more gracefully in the presence of parsing | |
1812 | errors. Flawed ca and conn section are discarded and pluto is started | |
1813 | if non-fatal errors only were encountered. If right=%peer.foo.bar | |
1814 | cannot be resolved by DNS then right=%any will be used so that passive | |
1815 | connections as a responder are still possible. | |
078ce348 | 1816 | |
a0a0bdd7 AS |
1817 | - The new pkcs11initargs parameter that can be placed in the |
1818 | setup config section of /etc/ipsec.conf allows the definition | |
1819 | of an argument string that is used with the PKCS#11 C_Initialize() | |
1820 | function. This non-standard feature is required by the NSS softoken | |
1821 | library. This patch was contributed by Robert Varga. | |
b6b90b68 | 1822 | |
a0a0bdd7 AS |
1823 | - Fixed a bug in ipsec starter introduced by strongswan-2.8.5 |
1824 | which caused a segmentation fault in the presence of unknown | |
1825 | or misspelt keywords in ipsec.conf. This bug fix was contributed | |
1826 | by Robert Varga. | |
1827 | ||
e3606f2b MW |
1828 | - Partial support for MOBIKE in IKEv2. The initiator acts on interface/ |
1829 | address configuration changes and updates IKE and IPsec SAs dynamically. | |
e93c68ba | 1830 | |
06651827 | 1831 | |
a3354a69 AS |
1832 | strongswan-4.1.3 |
1833 | ---------------- | |
1834 | ||
b6b90b68 | 1835 | - IKEv2 peer configuration selection now can be based on a given |
35d4809c AS |
1836 | certification authority using the rightca= statement. |
1837 | ||
1838 | - IKEv2 authentication based on RSA signatures now can handle multiple | |
41e16cf4 AS |
1839 | certificates issued for a given peer ID. This allows a smooth transition |
1840 | in the case of a peer certificate renewal. | |
a3354a69 | 1841 | |
998ca0ea MW |
1842 | - IKEv2: Support for requesting a specific virtual IP using leftsourceip on the |
1843 | client and returning requested virtual IPs using rightsourceip=%config | |
1844 | on the server. If the server does not support configuration payloads, the | |
1845 | client enforces its leftsourceip parameter. | |
1846 | ||
1847 | - The ./configure options --with-uid/--with-gid allow pluto and charon | |
1848 | to drop their privileges to a minimum and change to an other UID/GID. This | |
1849 | improves the systems security, as a possible intruder may only get the | |
1850 | CAP_NET_ADMIN capability. | |
1851 | ||
b6b90b68 | 1852 | - Further modularization of charon: Pluggable control interface and |
998ca0ea MW |
1853 | configuration backend modules provide extensibility. The control interface |
1854 | for stroke is included, and further interfaces using DBUS (NetworkManager) | |
1855 | or XML are on the way. A backend for storing configurations in the daemon | |
b6b90b68 | 1856 | is provided and more advanced backends (using e.g. a database) are trivial |
998ca0ea | 1857 | to implement. |
a3354a69 | 1858 | |
f3bb1bd0 | 1859 | - Fixed a compilation failure in libfreeswan occurring with Linux kernel |
41e16cf4 AS |
1860 | headers > 2.6.17. |
1861 | ||
1862 | ||
8ea7b96f AS |
1863 | strongswan-4.1.2 |
1864 | ---------------- | |
1865 | ||
e23d98a7 | 1866 | - Support for an additional Diffie-Hellman exchange when creating/rekeying |
37fb0355 MW |
1867 | a CHILD_SA in IKEv2 (PFS). PFS is enabled when the proposal contains a |
1868 | DH group (e.g. "esp=aes128-sha1-modp1536"). Further, DH group negotiation | |
1869 | is implemented properly for rekeying. | |
1870 | ||
1871 | - Support for the AES-XCBC-96 MAC algorithm for IPsec SAs when using IKEv2 | |
1872 | (requires linux >= 2.6.20). It is enabled using e.g. "esp=aes256-aesxcbc". | |
1873 | ||
d931f465 MW |
1874 | - Working IPv4-in-IPv6 and IPv6-in-IPv4 tunnels for linux >= 2.6.21. |
1875 | ||
37fb0355 MW |
1876 | - Added support for EAP modules which do not establish an MSK. |
1877 | ||
dfbe2a0f | 1878 | - Removed the dependencies from the /usr/include/linux/ headers by |
9f78f957 | 1879 | including xfrm.h, ipsec.h, and pfkeyv2.h in the distribution. |
b6b90b68 | 1880 | |
9f78f957 AS |
1881 | - crlNumber is now listed by ipsec listcrls |
1882 | ||
8ea7b96f AS |
1883 | - The xauth_modules.verify_secret() function now passes the |
1884 | connection name. | |
1885 | ||
e23d98a7 | 1886 | |
ed284399 MW |
1887 | strongswan-4.1.1 |
1888 | ---------------- | |
1889 | ||
1890 | - Server side cookie support. If to may IKE_SAs are in CONNECTING state, | |
1891 | cookies are enabled and protect against DoS attacks with faked source | |
1892 | addresses. Number of IKE_SAs in CONNECTING state is also limited per | |
1893 | peer address to avoid resource exhaustion. IKE_SA_INIT messages are | |
1894 | compared to properly detect retransmissions and incoming retransmits are | |
1895 | detected even if the IKE_SA is blocked (e.g. doing OCSP fetches). | |
1896 | ||
db88e37d AS |
1897 | - The IKEv2 daemon charon now supports dynamic http- and ldap-based CRL |
1898 | fetching enabled by crlcheckinterval > 0 and caching fetched CRLs | |
1899 | enabled by cachecrls=yes. | |
1900 | ||
3b4f7d92 AS |
1901 | - Added the configuration options --enable-nat-transport which enables |
1902 | the potentially insecure NAT traversal for IPsec transport mode and | |
1903 | --disable-vendor-id which disables the sending of the strongSwan | |
1904 | vendor ID. | |
1905 | ||
1906 | - Fixed a long-standing bug in the pluto IKEv1 daemon which caused | |
1907 | a segmentation fault if a malformed payload was detected in the | |
1908 | IKE MR2 message and pluto tried to send an encrypted notification | |
1909 | message. | |
1910 | ||
46b9ff68 AS |
1911 | - Added the NATT_IETF_02_N Vendor ID in order to support IKEv1 connections |
1912 | with Windows 2003 Server which uses a wrong VID hash. | |
1913 | ||
3b4f7d92 | 1914 | |
34bbd0c3 | 1915 | strongswan-4.1.0 |
cd3958f8 AS |
1916 | ---------------- |
1917 | ||
1918 | - Support of SHA2_384 hash function for protecting IKEv1 | |
1919 | negotiations and support of SHA2 signatures in X.509 certificates. | |
1920 | ||
1921 | - Fixed a serious bug in the computation of the SHA2-512 HMAC | |
1922 | function. Introduced automatic self-test of all IKEv1 hash | |
1923 | and hmac functions during pluto startup. Failure of a self-test | |
1924 | currently issues a warning only but does not exit pluto [yet]. | |
1925 | ||
9b45443d MW |
1926 | - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2. |
1927 | ||
c5d0fbb6 | 1928 | - Full support of CA information sections. ipsec listcainfos |
b6b90b68 | 1929 | now shows all collected crlDistributionPoints and OCSP |
c5d0fbb6 AS |
1930 | accessLocations. |
1931 | ||
69ed04bf AS |
1932 | - Support of the Online Certificate Status Protocol (OCSP) for IKEv2. |
1933 | This feature requires the HTTP fetching capabilities of the libcurl | |
1934 | library which must be enabled by setting the --enable-http configure | |
1935 | option. | |
1936 | ||
9b45443d MW |
1937 | - Refactored core of the IKEv2 message processing code, allowing better |
1938 | code reuse and separation. | |
1939 | ||
1940 | - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration | |
1941 | payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted | |
1942 | by the requestor and installed in a resolv.conf file. | |
1943 | ||
1944 | - The IKEv2 daemon charon installs a route for each IPsec policy to use | |
1945 | the correct source address even if an application does not explicitly | |
1946 | specify it. | |
1947 | ||
1948 | - Integrated the EAP framework into charon which loads pluggable EAP library | |
1949 | modules. The ipsec.conf parameter authby=eap initiates EAP authentication | |
1950 | on the client side, while the "eap" parameter on the server side defines | |
1951 | the EAP method to use for client authentication. | |
1952 | A generic client side EAP-Identity module and an EAP-SIM authentication | |
1953 | module using a third party card reader implementation are included. | |
1954 | ||
1955 | - Added client side support for cookies. | |
1956 | ||
1957 | - Integrated the fixes done at the IKEv2 interoperability bakeoff, including | |
1958 | strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor | |
1959 | fixes to enhance interoperability with other implementations. | |

1962 | strongswan-4.0.7 |
1963 | ---------------- | |
1964 | ||
6fdf5f44 AS |
1965 | - strongSwan now interoperates with the NCP Secure Entry Client, |
1966 | the Shrew Soft VPN Client, and the Cisco VPN client, doing both | |
1967 | XAUTH and Mode Config. | |
1c266d7d AS |
1968 | |
1969 | - UNITY attributes are now recognized and UNITY_BANNER is set | |
1970 | to a default string. | |
1971 | ||

2b4405a3 MW |
1973 | strongswan-4.0.6 |
1974 | ---------------- | |
1975 | ||
e38a15d4 AS |
1976 | - IKEv1: Support for extended authentication (XAUTH) in combination |
1977 | with ISAKMP Main Mode RSA or PSK authentication. Both client and | |
1978 | server side were implemented. Handling of user credentials can | |
1979 | be done by a run-time loadable XAUTH module. By default user | |
b6b90b68 MW |
1980 | credentials are stored in ipsec.secrets. |
1981 | ||
2b4405a3 MW |
1982 | - IKEv2: Support for reauthentication when rekeying |
1983 | ||
5903179b | 1984 | - IKEv2: Support for transport mode |
af87afed | 1985 | |
5903179b | 1986 | - fixed a lot of bugs related to byte order |
2b4405a3 | 1987 | |
5903179b | 1988 | - various other bugfixes |
2b4405a3 MW |
1989 | |
1990 | ||
0cd645d2 AS |
1991 | strongswan-4.0.5 |
1992 | ---------------- | |
1993 | ||
1994 | - IKEv1: Implementation of ModeConfig push mode via the new connection | |
1995 | keyword modeconfig=push allows interoperability with Cisco VPN gateways. | |
1996 | ||
1997 | - IKEv1: The command ipsec statusall now shows "DPD active" for all | |
1998 | ISAKMP SAs that are under active Dead Peer Detection control. | |
1999 | ||
2000 | - IKEv2: Charon's logging and debugging framework has been completely rewritten. | |
2001 | Instead of logger, special printf() functions are used to directly | |
2002 | print objects like hosts (%H) identifications (%D), certificates (%Q), | |
2003 | etc. The number of debugging levels have been reduced to: | |
03bf883d | 2004 | |
0cd645d2 | 2005 | 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private) |
03bf883d | 2006 | |
0cd645d2 AS |
2007 | The debugging levels can either be specified statically in ipsec.conf as |
2008 | ||
2009 | config setup | |
03bf883d | 2010 | charondebug="lib 1, cfg 3, net 2" |
0cd645d2 | 2011 | |
03bf883d | 2012 | or changed at runtime via stroke as |
0cd645d2 | 2013 | |
03bf883d | 2014 | ipsec stroke loglevel cfg 2 |
0cd645d2 AS |

48dc3934 MW |
2017 | strongswan-4.0.4 |
2018 | ---------------- | |
2019 | ||
2020 | - Implemented full support for IPv6-in-IPv6 tunnels. | |
2021 | ||
2022 | - Added configuration options for dead peer detection in IKEv2. dpd_action | |
2023 | types "clear", "hold" and "restart" are supported. The dpd_timeout | |
2024 | value is not used, as the normal retransmission policy applies to | |
2025 | detect dead peers. The dpd_delay parameter enables sending of empty | |
2026 | informational message to detect dead peers in case of inactivity. | |
2027 | ||
2028 | - Added support for preshared keys in IKEv2. PSK keys configured in | |
2029 | ipsec.secrets are loaded. The authby parameter specifies the authentication | |
2030 | method to authentificate ourself, the other peer may use PSK or RSA. | |
2031 | ||
2032 | - Changed retransmission policy to respect the keyingtries parameter. | |
2033 | ||
112ad7c3 AS |
2034 | - Added private key decryption. PEM keys encrypted with AES-128/192/256 |
2035 | or 3DES are supported. | |
48dc3934 MW |
2036 | |
2037 | - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to | |
2038 | encrypt IKE traffic. | |
2039 | ||
2040 | - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates | |
2041 | signed with such a hash algorithm. | |
2042 | ||
2043 | - Added initial support for updown scripts. The actions up-host/client and | |
2044 | down-host/client are executed. The leftfirewall=yes parameter | |
2045 | uses the default updown script to insert dynamic firewall rules, a custom | |
2046 | updown script may be specified with the leftupdown parameter. | |
2047 | ||
2048 | ||
a1310b6b MW |
2049 | strongswan-4.0.3 |
2050 | ---------------- | |
2051 | ||
2052 | - Added support for the auto=route ipsec.conf parameter and the | |
b6b90b68 MW |
2053 | ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and |
2054 | CHILD_SAs dynamically on demand when traffic is detected by the | |
a1310b6b MW |
2055 | kernel. |
2056 | ||
2057 | - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter. | |
2058 | As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only | |
2059 | new keys are generated using perfect forward secrecy. An optional flag | |
2060 | which enforces reauthentication will be implemented later. | |
2061 | ||
b425d998 AS |
2062 | - "sha" and "sha1" are now treated as synonyms in the ike= and esp= |
2063 | algorithm configuration statements. | |
2064 | ||
2065 | ||
bf4df11f AS |
2066 | strongswan-4.0.2 |
2067 | ---------------- | |
2068 | ||
623d3dcf AS |
2069 | - Full X.509 certificate trust chain verification has been implemented. |
2070 | End entity certificates can be exchanged via CERT payloads. The current | |
2071 | default is leftsendcert=always, since CERTREQ payloads are not supported | |
2072 | yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls. | |
efa40c11 | 2073 | |
b6b90b68 | 2074 | - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2 |
efa40c11 | 2075 | would offer more possibilities for traffic selection, but the Linux kernel |
b6b90b68 | 2076 | currently does not support it. That's why we stick with these simple |
efa40c11 MW |
2077 | ipsec.conf rules for now. |
2078 | ||
623d3dcf AS |
2079 | - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no |
2080 | IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear, | |
2081 | dpddelay=60s). | |
2082 | ||
efa40c11 MW |
2083 | - Initial NAT traversal support in IKEv2. Charon includes NAT detection |
2084 | notify payloads to detect NAT routers between the peers. It switches | |
2085 | to port 4500, uses UDP encapsulated ESP packets, handles peer address | |
2086 | changes gracefully and sends keep alive message periodically. | |
2087 | ||
b6b90b68 MW |
2088 | - Reimplemented IKE_SA state machine for charon, which allows simultaneous |
2089 | rekeying, more shared code, cleaner design, proper retransmission | |
efa40c11 MW |
2090 | and a more extensible code base. |
2091 | ||
cfd8b27f AS |
2092 | - The mixed PSK/RSA roadwarrior detection capability introduced by the |
2093 | strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal | |
2094 | payloads by the responder right before any defined IKE Main Mode state had | |
2095 | been established. Although any form of bad proposal syntax was being correctly | |
2096 | detected by the payload parser, the subsequent error handler didn't check | |
2097 | the state pointer before logging current state information, causing an | |
2098 | immediate crash of the pluto keying daemon due to a NULL pointer. | |
2099 | ||
bf4df11f | 2100 | |
7e81e975 MW |
2101 | strongswan-4.0.1 |
2102 | ---------------- | |
2103 | ||
b6b90b68 | 2104 | - Added algorithm selection to charon: New default algorithms for |
c15c3d4b MW |
2105 | ike=aes128-sha-modp2048, as both daemons support it. The default |
2106 | for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles | |
2107 | the ike/esp parameter the same way as pluto. As this syntax does | |
b6b90b68 | 2108 | not allow specification of a pseudo random function, the same |
c15c3d4b MW |
2109 | algorithm as for integrity is used (currently sha/md5). Supported |
2110 | algorithms for IKE: | |
2111 | Encryption: aes128, aes192, aes256 | |
2112 | Integrity/PRF: md5, sha (using hmac) | |
2113 | DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192 | |
2114 | and for ESP: | |
b6b90b68 | 2115 | Encryption: aes128, aes192, aes256, 3des, blowfish128, |
c15c3d4b MW |
2116 | blowfish192, blowfish256 |
2117 | Integrity: md5, sha1 | |
2118 | More IKE encryption algorithms will come after porting libcrypto into | |
b6b90b68 | 2119 | libstrongswan. |
f2c2d395 | 2120 | |
c15c3d4b MW |
2121 | - initial support for rekeying CHILD_SAs using IKEv2. Currently no |
2122 | perfect forward secrecy is used. The rekeying parameters rekey, | |
22ff6f57 | 2123 | rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported |
c15c3d4b MW |
2124 | when using IKEv2. WARNING: charon currently is unable to handle |
2125 | simultaneous rekeying. To avoid such a situation, use a large | |
2126 | rekeyfuzz, or even better, set rekey=no on one peer. | |
22ff6f57 | 2127 | |
7e81e975 MW |
2128 | - support for host2host, net2net, host2net (roadwarrior) tunnels |
2129 | using predefined RSA certificates (see uml scenarios for | |
2130 | configuration examples). | |
2131 | ||
f2c2d395 MW |
2132 | - new build environment featuring autotools. Features such |
2133 | as HTTP, LDAP and smartcard support may be enabled using | |
b6b90b68 | 2134 | the ./configure script. Changing install directories |
f2c2d395 MW |
2135 | is possible, too. See ./configure --help for more details. |
2136 | ||
22ff6f57 MW |
2137 | - better integration of charon with ipsec starter, which allows |
2138 | (almost) transparent operation with both daemons. charon | |
2139 | handles ipsec commands up, down, status, statusall, listall, | |
2140 | listcerts and allows proper load, reload and delete of connections | |
2141 | via ipsec starter. | |

b425d998 | 2143 | |
9820c0e2 MW |
2144 | strongswan-4.0.0 |
2145 | ---------------- | |
2146 | ||
2147 | - initial support of the IKEv2 protocol. Connections in | |
b6b90b68 | 2148 | ipsec.conf designated by keyexchange=ikev2 are negotiated |
9820c0e2 MW |
2149 | by the new IKEv2 charon keying daemon whereas those marked |
2150 | by keyexchange=ikev1 or the default keyexchange=ike are | |
2151 | handled thy the IKEv1 pluto keying daemon. Currently only | |
2152 | a limited subset of functions are available with IKEv2 | |
2153 | (Default AES encryption, authentication based on locally | |
2154 | imported X.509 certificates, unencrypted private RSA keys | |
2155 | in PKCS#1 file format, limited functionality of the ipsec | |
2156 | status command). | |
2157 | ||
2158 | ||
997358a6 MW |
2159 | strongswan-2.7.0 |
2160 | ---------------- | |
2161 | ||
2162 | - the dynamic iptables rules from the _updown_x509 template | |
2163 | for KLIPS and the _updown_policy template for NETKEY have | |
2164 | been merged into the default _updown script. The existing | |
2165 | left|rightfirewall keyword causes the automatic insertion | |
2166 | and deletion of ACCEPT rules for tunneled traffic upon | |
2167 | the successful setup and teardown of an IPsec SA, respectively. | |
2168 | left|rightfirwall can be used with KLIPS under any Linux 2.4 | |
2169 | kernel or with NETKEY under a Linux kernel version >= 2.6.16 | |
f3bb1bd0 | 2170 | in conjunction with iptables >= 1.3.5. For NETKEY under a Linux |
997358a6 MW |
2171 | kernel version < 2.6.16 which does not support IPsec policy |
2172 | matching yet, please continue to use a copy of the _updown_espmark | |
2173 | template loaded via the left|rightupdown keyword. | |
2174 | ||
2175 | - a new left|righthostaccess keyword has been introduced which | |
2176 | can be used in conjunction with left|rightfirewall and the | |
2177 | default _updown script. By default leftfirewall=yes inserts | |
2178 | a bi-directional iptables FORWARD rule for a local client network | |
2179 | with a netmask different from 255.255.255.255 (single host). | |
2180 | This does not allow to access the VPN gateway host via its | |
2181 | internal network interface which is part of the client subnet | |
2182 | because an iptables INPUT and OUTPUT rule would be required. | |
2183 | lefthostaccess=yes will cause this additional ACCEPT rules to | |
b6b90b68 | 2184 | be inserted. |
997358a6 MW |
2185 | |
2186 | - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal | |
2187 | payload is preparsed in order to find out whether the roadwarrior | |
2188 | requests PSK or RSA so that a matching connection candidate can | |
2189 | be found. | |
2190 | ||
2191 | ||
2192 | strongswan-2.6.4 | |
2193 | ---------------- | |
2194 | ||
2195 | - the new _updown_policy template allows ipsec policy based | |
2196 | iptables firewall rules. Required are iptables version | |
2197 | >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes | |
b6b90b68 | 2198 | the _updown_espmark template, so that no INPUT mangle rules |
997358a6 MW |
2199 | are required any more. |
2200 | ||
2201 | - added support of DPD restart mode | |
2202 | ||
2203 | - ipsec starter now allows the use of wildcards in include | |
2204 | statements as e.g. in "include /etc/my_ipsec/*.conf". | |
2205 | Patch courtesy of Matthias Haas. | |
2206 | ||
2207 | - the Netscape OID 'employeeNumber' is now recognized and can be | |
2208 | used as a Relative Distinguished Name in certificates. | |
2209 | ||
2210 | ||
2211 | strongswan-2.6.3 | |

b6b90b68 | 2214 | - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec |
997358a6 MW |
2215 | command and not of ipsec setup any more. |
2216 | ||
2217 | - ipsec starter now supports AH authentication in conjunction with | |
2218 | ESP encryption. AH authentication is configured in ipsec.conf | |
2219 | via the auth=ah parameter. | |
b6b90b68 | 2220 | |
997358a6 MW |
2221 | - The command ipsec scencrypt|scdecrypt <args> is now an alias for |
2222 | ipsec whack --scencrypt|scdecrypt <args>. | |
2223 | ||
2224 | - get_sa_info() now determines for the native netkey IPsec stack | |
2225 | the exact time of the last use of an active eroute. This information | |
2226 | is used by the Dead Peer Detection algorithm and is also displayed by | |
2227 | the ipsec status command. | |
b6b90b68 | 2228 | |
997358a6 MW |
2229 | |
2230 | strongswan-2.6.2 | |
2231 | ---------------- | |
2232 | ||
2233 | - running under the native Linux 2.6 IPsec stack, the function | |
2234 | get_sa_info() is called by ipsec auto --status to display the current | |
2235 | number of transmitted bytes per IPsec SA. | |
2236 | ||
2237 | - get_sa_info() is also used by the Dead Peer Detection process to detect | |
2238 | recent ESP activity. If ESP traffic was received from the peer within | |
2239 | the last dpd_delay interval then no R_Y_THERE notification must be sent. | |
2240 | ||
2241 | - strongSwan now supports the Relative Distinguished Name "unstructuredName" | |
2242 | in ID_DER_ASN1_DN identities. The following notations are possible: | |
2243 | ||
2244 | rightid="unstructuredName=John Doe" | |
2245 | rightid="UN=John Doe" | |
2246 | ||
2247 | - fixed a long-standing bug which caused PSK-based roadwarrior connections | |
2248 | to segfault in the function id.c:same_id() called by keys.c:get_secret() | |
2249 | if an FQDN, USER_FQDN, or Key ID was defined, as in the following example. | |
2250 | ||
2251 | conn rw | |
2252 | right=%any | |
2253 | rightid=@foo.bar | |
2254 | authby=secret | |
2255 | ||
2256 | - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall). | |
2257 | ||
2258 | - ipsec starter didn't set host_addr and client.addr ports in whack msg. | |
2259 | ||
2260 | - in order to guarantee backwards-compatibility with the script-based | |
2261 | auto function (e.g. auto --replace), the ipsec starter scripts stores | |
2262 | the defaultroute information in the temporary file /var/run/ipsec.info. | |
2263 | ||
2264 | - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH | |
2265 | Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config | |
2266 | servers. | |
2267 | ||
2268 | - the ipsec starter now also recognizes the parameters authby=never and | |
2269 | type=passthrough|pass|drop|reject. | |
2270 | ||
2271 | ||
2272 | strongswan-2.6.1 | |
2273 | ---------------- | |
2274 | ||
2275 | - ipsec starter now supports the also parameter which allows | |
2276 | a modular structure of the connection definitions. Thus | |
2277 | "ipsec start" is now ready to replace "ipsec setup". | |
2278 | ||
2279 | ||
2280 | strongswan-2.6.0 | |
2281 | ---------------- | |
2282 | ||
2283 | - Mathieu Lafon's popular ipsec starter tool has been added to the | |
2284 | strongSwan distribution. Many thanks go to Stephan Scholz from astaro | |
2285 | for his integration work. ipsec starter is a C program which is going | |
2286 | to replace the various shell and awk starter scripts (setup, _plutoload, | |
2287 | _plutostart, _realsetup, _startklips, _confread, and auto). Since | |
2288 | ipsec.conf is now parsed only once, the starting of multiple tunnels is | |
2289 | accelerated tremedously. | |
2290 | ||
2291 | - Added support of %defaultroute to the ipsec starter. If the IP address | |
b6b90b68 | 2292 | changes, a HUP signal to the ipsec starter will automatically |
997358a6 MW |
2293 | reload pluto's connections. |
2294 | ||
2295 | - moved most compile time configurations from pluto/Makefile to | |
2296 | Makefile.inc by defining the options USE_LIBCURL, USE_LDAP, | |
2297 | USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE. | |
2298 | ||
2299 | - removed the ipsec verify and ipsec newhostkey commands | |
2300 | ||
2301 | - fixed some 64-bit issues in formatted print statements | |
2302 | ||
2303 | - The scepclient functionality implementing the Simple Certificate | |
2304 | Enrollment Protocol (SCEP) is nearly complete but hasn't been | |
2305 | documented yet. | |
2306 | ||
2307 | ||
2308 | strongswan-2.5.7 | |
2309 | ---------------- | |
2310 | ||
2311 | - CA certicates are now automatically loaded from a smartcard | |
2312 | or USB crypto token and appear in the ipsec auto --listcacerts | |
2313 | listing. | |
2314 | ||
2315 | ||
2316 | strongswan-2.5.6 | |
2317 | ---------------- | |
2318 | ||
2319 | - when using "ipsec whack --scencrypt <data>" with a PKCS#11 | |
2320 | library that does not support the C_Encrypt() Cryptoki | |
2321 | function (e.g. OpenSC), the RSA encryption is done in | |
2322 | software using the public key fetched from the smartcard. | |
2323 | ||
b6b90b68 | 2324 | - The scepclient function now allows to define the |
997358a6 MW |
2325 | validity of a self-signed certificate using the --days, |
2326 | --startdate, and --enddate options. The default validity | |
2327 | has been changed from one year to five years. | |
2328 | ||
2329 | ||
2330 | strongswan-2.5.5 | |
2331 | ---------------- | |
2332 | ||
2333 | - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11 | |
2334 | interface to other applications for RSA encryption and decryption | |
2335 | via the whack interface. Notation: | |
2336 | ||
2337 | ipsec whack --scencrypt <data> | |
2338 | [--inbase 16|hex|64|base64|256|text|ascii] | |
2339 | [--outbase 16|hex|64|base64|256|text|ascii] | |
2340 | [--keyid <keyid>] | |
2341 | ||
2342 | ipsec whack --scdecrypt <data> | |
2343 | [--inbase 16|hex|64|base64|256|text|ascii] | |
2344 | [--outbase 16|hex|64|base64|256|text|ascii] | |
2345 | [--keyid <keyid>] | |
2346 | ||
b6b90b68 | 2347 | The default setting for inbase and outbase is hex. |
997358a6 MW |
2348 | |
2349 | The new proxy interface can be used for securing symmetric | |
2350 | encryption keys required by the cryptoloop or dm-crypt | |
2351 | disk encryption schemes, especially in the case when | |
2352 | pkcs11keepstate=yes causes pluto to lock the pkcs11 slot | |
2353 | permanently. | |
2354 | ||
2355 | - if the file /etc/ipsec.secrets is lacking during the startup of | |
2356 | pluto then the root-readable file /etc/ipsec.d/private/myKey.der | |
2357 | containing a 2048 bit RSA private key and a matching self-signed | |
2358 | certificate stored in the file /etc/ipsec.d/certs/selfCert.der | |
2359 | is automatically generated by calling the function | |
2360 | ||
2361 | ipsec scepclient --out pkcs1 --out cert-self | |
2362 | ||
2363 | scepclient was written by Jan Hutter and Martin Willi, students | |
2364 | at the University of Applied Sciences in Rapperswil, Switzerland. | |
2365 | ||
2366 | ||
2367 | strongswan-2.5.4 | |
2368 | ---------------- | |
2369 | ||
2370 | - the current extension of the PKCS#7 framework introduced | |
2371 | a parsing error in PKCS#7 wrapped X.509 certificates that are | |
2372 | e.g. transmitted by Windows XP when multi-level CAs are used. | |
2373 | the parsing syntax has been fixed. | |
2374 | ||
2375 | - added a patch by Gerald Richter which tolerates multiple occurrences | |
2376 | of the ipsec0 interface when using KLIPS. | |
2377 | ||
2378 | ||
2379 | strongswan-2.5.3 | |
2380 | ---------------- | |
2381 | ||
2382 | - with gawk-3.1.4 the word "default2 has become a protected | |
2383 | keyword for use in switch statements and cannot be used any | |
2384 | more in the strongSwan scripts. This problem has been | |
2385 | solved by renaming "default" to "defaults" and "setdefault" | |
2386 | in the scripts _confread and auto, respectively. | |
2387 | ||
2388 | - introduced the parameter leftsendcert with the values | |
2389 | ||
2390 | always|yes (the default, always send a cert) | |
2391 | ifasked (send the cert only upon a cert request) | |
2392 | never|no (never send a cert, used for raw RSA keys and | |
b6b90b68 | 2393 | self-signed certs) |
997358a6 MW |
2394 | |
2395 | - fixed the initialization of the ESP key length to a default of | |
2396 | 128 bits in the case that the peer does not send a key length | |
2397 | attribute for AES encryption. | |
2398 | ||
2399 | - applied Herbert Xu's uniqueIDs patch | |
2400 | ||
2401 | - applied Herbert Xu's CLOEXEC patches | |
2402 | ||
2403 | ||
2404 | strongswan-2.5.2 | |
2405 | ---------------- | |
2406 | ||
2407 | - CRLs can now be cached also in the case when the issuer's | |
2408 | certificate does not contain a subjectKeyIdentifier field. | |
2409 | In that case the subjectKeyIdentifier is computed by pluto as the | |
2410 | 160 bit SHA-1 hash of the issuer's public key in compliance | |
2411 | with section 4.2.1.2 of RFC 3280. | |
2412 | ||
2413 | - Fixed a bug introduced by strongswan-2.5.1 which eliminated | |
2414 | not only multiple Quick Modes of a given connection but also | |
2415 | multiple connections between two security gateways. | |
2416 | ||
2417 | ||
2418 | strongswan-2.5.1 | |
2419 | ---------------- | |
2420 | ||
2421 | - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute | |
2422 | installed either by setting auto=route in ipsec.conf or by | |
2423 | a connection put into hold, generates an XFRM_AQUIRE event | |
2424 | for each packet that wants to use the not-yet exisiting | |
2425 | tunnel. Up to now each XFRM_AQUIRE event led to an entry in | |
2426 | the Quick Mode queue, causing multiple IPsec SA to be | |
2427 | established in rapid succession. Starting with strongswan-2.5.1 | |
2428 | only a single IPsec SA is established per host-pair connection. | |
2429 | ||
2430 | - Right after loading the PKCS#11 module, all smartcard slots are | |
2431 | searched for certificates. The result can be viewed using | |
2432 | the command | |
2433 | ||
2434 | ipsec auto --listcards | |
2435 | ||
2436 | The certificate objects found in the slots are numbered | |
2437 | starting with #1, #2, etc. This position number can be used to address | |
2438 | certificates (leftcert=%smartcard) and keys (: PIN %smartcard) | |
2439 | in ipsec.conf and ipsec.secrets, respectively: | |
2440 | ||
2441 | %smartcard (selects object #1) | |
2442 | %smartcard#1 (selects object #1) | |
2443 | %smartcard#3 (selects object #3) | |
2444 | ||
2445 | As an alternative the existing retrieval scheme can be used: | |
2446 | ||
2447 | %smartcard:45 (selects object with id=45) | |
2448 | %smartcard0 (selects first object in slot 0) | |
2449 | %smartcard4:45 (selects object in slot 4 with id=45) | |
2450 | ||
2451 | - Depending on the settings of CKA_SIGN and CKA_DECRYPT | |
2452 | private key flags either C_Sign() or C_Decrypt() is used | |
2453 | to generate a signature. | |
2454 | ||
2455 | - The output buffer length parameter siglen in C_Sign() | |
2456 | is now initialized to the actual size of the output | |
2457 | buffer prior to the function call. This fixes the | |
2458 | CKR_BUFFER_TOO_SMALL error that could occur when using | |
2459 | the OpenSC PKCS#11 module. | |
2460 | ||
2461 | - Changed the initialization of the PKCS#11 CK_MECHANISM in | |
2462 | C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }. | |
2463 | ||
2464 | - Refactored the RSA public/private key code and transferred it | |
2465 | from keys.c to the new pkcs1.c file as a preparatory step | |
2466 | towards the release of the SCEP client. | |
2467 | ||
2468 | ||
2469 | strongswan-2.5.0 | |
2470 | ---------------- | |
2471 | ||
2472 | - The loading of a PKCS#11 smartcard library module during | |
2473 | runtime does not require OpenSC library functions any more | |
2474 | because the corresponding code has been integrated into | |
2475 | smartcard.c. Also the RSAREF pkcs11 header files have been | |
2476 | included in a newly created pluto/rsaref directory so that | |
2477 | no external include path has to be defined any longer. | |
2478 | ||
2479 | - A long-awaited feature has been implemented at last: | |
2480 | The local caching of CRLs fetched via HTTP or LDAP, activated | |
2481 | by the parameter cachecrls=yes in the config setup section | |
2482 | of ipsec.conf. The dynamically fetched CRLs are stored under | |
2483 | a unique file name containing the issuer's subjectKeyID | |
2484 | in /etc/ipsec.d/crls. | |
b6b90b68 | 2485 | |
997358a6 MW |
2486 | - Applied a one-line patch courtesy of Michael Richardson |
2487 | from the Openswan project which fixes the kernel-oops | |
2488 | in KLIPS when an snmp daemon is running on the same box. | |
2489 | ||
2490 | ||
2491 | strongswan-2.4.4 | |
2492 | ---------------- | |
2493 | ||
2494 | - Eliminated null length CRL distribution point strings. | |
2495 | ||
2496 | - Fixed a trust path evaluation bug introduced with 2.4.3 | |
2497 | ||
2498 | ||
2499 | strongswan-2.4.3 | |
2500 | ---------------- | |
2501 | ||
2502 | - Improved the joint OCSP / CRL revocation policy. | |
2503 | OCSP responses have precedence over CRL entries. | |
2504 | ||
2505 | - Introduced support of CRLv2 reason codes. | |
2506 | ||
2507 | - Fixed a bug with key-pad equipped readers which caused | |
2508 | pluto to prompt for the pin via the console when the first | |
2509 | occasion to enter the pin via the key-pad was missed. | |
2510 | ||
2511 | - When pluto is built with LDAP_V3 enabled, the library | |
2512 | liblber required by newer versions of openldap is now | |
2513 | included. | |
2514 | ||
2515 | ||
2516 | strongswan-2.4.2 | |
2517 | ---------------- | |
2518 | ||
2519 | - Added the _updown_espmark template which requires all | |
2520 | incoming ESP traffic to be marked with a default mark | |
2521 | value of 50. | |
b6b90b68 | 2522 | |
997358a6 MW |
2523 | - Introduced the pkcs11keepstate parameter in the config setup |
2524 | section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11 | |
b6b90b68 | 2525 | session and login states are kept as long as possible during |
997358a6 MW |
2526 | the lifetime of pluto. This means that a PIN entry via a key |
2527 | pad has to be done only once. | |
2528 | ||
2529 | - Introduced the pkcs11module parameter in the config setup | |
2530 | section of ipsec.conf which specifies the PKCS#11 module | |
2531 | to be used with smart cards. Example: | |
b6b90b68 | 2532 | |
997358a6 | 2533 | pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo |
b6b90b68 | 2534 | |
997358a6 MW |
2535 | - Added support of smartcard readers equipped with a PIN pad. |
2536 | ||
2537 | - Added patch by Jay Pfeifer which detects when netkey | |
2538 | modules have been statically built into the Linux 2.6 kernel. | |
2539 | ||
2540 | - Added two patches by Herbert Xu. The first uses ip xfrm | |
2541 | instead of setkey to flush the IPsec policy database. The | |
2542 | second sets the optional flag in inbound IPComp SAs only. | |
b6b90b68 | 2543 | |
997358a6 MW |
2544 | - Applied Ulrich Weber's patch which fixes an interoperability |
2545 | problem between native IPsec and KLIPS systems caused by | |
2546 | setting the replay window to 32 instead of 0 for ipcomp. | |
2547 | ||
2548 | ||
2549 | strongswan-2.4.1 | |
2550 | ---------------- | |
2551 | ||
2552 | - Fixed a bug which caused an unwanted Mode Config request | |
2553 | to be initiated in the case where "right" was used to denote | |
2554 | the local side in ipsec.conf and "left" the remote side, | |
2555 | contrary to the recommendation that "right" be remote and | |
2556 | "left" be"local". | |
2557 | ||
2558 | ||
2559 | strongswan-2.4.0a | |
2560 | ----------------- | |
2561 | ||
2562 | - updated Vendor ID to strongSwan-2.4.0 | |
2563 | ||
2564 | - updated copyright statement to include David Buechi and | |
2565 | Michael Meier | |
b6b90b68 MW |
2566 | |
2567 | ||
997358a6 MW |
2568 | strongswan-2.4.0 |
2569 | ---------------- | |
2570 | ||
2571 | - strongSwan now communicates with attached smartcards and | |
2572 | USB crypto tokens via the standardized PKCS #11 interface. | |
2573 | By default the OpenSC library from www.opensc.org is used | |
2574 | but any other PKCS#11 library could be dynamically linked. | |
2575 | strongSwan's PKCS#11 API was implemented by David Buechi | |
2576 | and Michael Meier, both graduates of the Zurich University | |
2577 | of Applied Sciences in Winterthur, Switzerland. | |
2578 | ||
2579 | - When a %trap eroute is triggered by an outgoing IP packet | |
2580 | then the native IPsec stack of the Linux 2.6 kernel [often/ | |
2581 | always?] returns an XFRM_ACQUIRE message with an undefined | |
2582 | protocol family field and the connection setup fails. | |
2583 | As a workaround IPv4 (AF_INET) is now assumed. | |
b6b90b68 MW |
2584 | |
2585 | - the results of the UML test scenarios are now enhanced | |
997358a6 | 2586 | with block diagrams of the virtual network topology used |
b6b90b68 | 2587 | in a particular test. |
997358a6 MW |
2588 | |
2589 | ||
2590 | strongswan-2.3.2 | |
2591 | ---------------- | |
2592 | ||
2593 | - fixed IV used to decrypt informational messages. | |
2594 | This bug was introduced with Mode Config functionality. | |
b6b90b68 | 2595 | |
997358a6 MW |
2596 | - fixed NCP Vendor ID. |
2597 | ||
2598 | - undid one of Ulrich Weber's maximum udp size patches | |
2599 | because it caused a segmentation fault with NAT-ed | |
2600 | Delete SA messages. | |
b6b90b68 | 2601 | |
997358a6 MW |
2602 | - added UML scenarios wildcards and attr-cert which |
2603 | demonstrate the implementation of IPsec policies based | |
2604 | on wildcard parameters contained in Distinguished Names and | |
2605 | on X.509 attribute certificates, respectively. | |
2606 | ||
2607 | ||
2608 | strongswan-2.3.1 | |
2609 | ---------------- | |
2610 | ||
2611 | - Added basic Mode Config functionality | |
2612 | ||
2613 | - Added Mathieu Lafon's patch which upgrades the status of | |
2614 | the NAT-Traversal implementation to RFC 3947. | |
b6b90b68 | 2615 | |
997358a6 MW |
2616 | - The _startklips script now also loads the xfrm4_tunnel |
2617 | module. | |
b6b90b68 | 2618 | |
997358a6 MW |
2619 | - Added Ulrich Weber's netlink replay window size and |
2620 | maximum udp size patches. | |
2621 | ||
2622 | - UML testing now uses the Linux 2.6.10 UML kernel by default. | |
b6b90b68 | 2623 | |
997358a6 MW |
2624 | |
2625 | strongswan-2.3.0 | |
2626 | ---------------- | |
2627 | ||
2628 | - Eric Marchionni and Patrik Rayo, both recent graduates from | |
2629 | the Zuercher Hochschule Winterthur in Switzerland, created a | |
2630 | User-Mode-Linux test setup for strongSwan. For more details | |
2631 | please read the INSTALL and README documents in the testing | |
2632 | subdirectory. | |
2633 | ||
2634 | - Full support of group attributes based on X.509 attribute | |
b6b90b68 | 2635 | certificates. Attribute certificates can be generated |
997358a6 | 2636 | using the openac facility. For more details see |
b6b90b68 | 2637 | |
997358a6 | 2638 | man ipsec_openac. |
b6b90b68 | 2639 | |
997358a6 MW |
2640 | The group attributes can be used in connection definitions |
2641 | in order to give IPsec access to specific user groups. | |
2642 | This is done with the new parameter left|rightgroups as in | |
b6b90b68 | 2643 | |
997358a6 MW |
2644 | rightgroups="Research, Sales" |
2645 | ||
2646 | giving access to users possessing the group attributes | |
2647 | Research or Sales, only. | |
2648 | ||
2649 | - In Quick Mode clients with subnet mask /32 are now | |
b6b90b68 | 2650 | coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should |
997358a6 MW |
2651 | fix rekeying problems with the SafeNet/SoftRemote and NCP |
2652 | Secure Entry Clients. | |
2653 | ||
2654 | - Changed the defaults of the ikelifetime and keylife parameters | |
2655 | to 3h and 1h, respectively. The maximum allowable values are | |
2656 | now both set to 24 h. | |
2657 | ||
2658 | - Suppressed notification wars between two IPsec peers that | |
2659 | could e.g. be triggered by incorrect ISAKMP encryption. | |
2660 | ||
2661 | - Public RSA keys can now have identical IDs if either the | |
2662 | issuing CA or the serial number is different. The serial | |
2663 | number of a certificate is now shown by the command | |
b6b90b68 | 2664 | |
997358a6 MW |
2665 | ipsec auto --listpubkeys |
2666 | ||
2667 | ||
2668 | strongswan-2.2.2 | |
2669 | ---------------- | |
2670 | ||
2671 | - Added Tuomo Soini's sourceip feature which allows a strongSwan | |
2672 | roadwarrior to use a fixed Virtual IP (see README section 2.6) | |
2673 | and reduces the well-known four tunnel case on VPN gateways to | |
2674 | a single tunnel definition (see README section 2.4). | |
2675 | ||
f3bb1bd0 | 2676 | - Fixed a bug occurring with NAT-Traversal enabled when the responder |
997358a6 MW |
2677 | suddenly turns initiator and the initiator cannot find a matching |
2678 | connection because of the floated IKE port 4500. | |
b6b90b68 | 2679 | |
997358a6 MW |
2680 | - Removed misleading ipsec verify command from barf. |
2681 | ||
2682 | - Running under the native IP stack, ipsec --version now shows | |
2683 | the Linux kernel version (courtesy to the Openswan project). | |
2684 | ||
2685 | ||
2686 | strongswan-2.2.1 | |
2687 | ---------------- | |
2688 | ||
2689 | - Introduced the ipsec auto --listalgs monitoring command which lists | |
2690 | all currently registered IKE and ESP algorithms. | |
2691 | ||
f3bb1bd0 | 2692 | - Fixed a bug in the ESP algorithm selection occurring when the strict flag |
997358a6 | 2693 | is set and the first proposed transform does not match. |
b6b90b68 | 2694 | |
997358a6 | 2695 | - Fixed another deadlock in the use of the lock_certs_and_keys() mutex, |
f3bb1bd0 | 2696 | occurring when a smartcard is present. |
997358a6 MW |
2697 | |
2698 | - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event. | |
b6b90b68 | 2699 | |
997358a6 MW |
2700 | - Fixed the printing of the notification names (null) |
2701 | ||
2702 | - Applied another of Herbert Xu's Netlink patches. | |
2703 | ||
2704 | ||
2705 | strongswan-2.2.0 | |
2706 | ---------------- | |
2707 | ||
2708 | - Support of Dead Peer Detection. The connection parameter | |
2709 | ||
2710 | dpdaction=clear|hold | |
b6b90b68 | 2711 | |
997358a6 MW |
2712 | activates DPD for the given connection. |
2713 | ||
2714 | - The default Opportunistic Encryption (OE) policy groups are not | |
2715 | automatically included anymore. Those wishing to activate OE can include | |
2716 | the policy group with the following statement in ipsec.conf: | |
b6b90b68 | 2717 | |
997358a6 | 2718 | include /etc/ipsec.d/examples/oe.conf |
b6b90b68 | 2719 | |
997358a6 MW |
2720 | The default for [right|left]rsasigkey is now set to %cert. |
2721 | ||
2722 | - strongSwan now has a Vendor ID of its own which can be activated | |
2723 | using the compile option VENDORID | |
2724 | ||
2725 | - Applied Herbert Xu's patch which sets the compression algorithm correctly. | |
2726 | ||
2727 | - Applied Herbert Xu's patch fixing an ESPINUDP problem | |
2728 | ||
2729 | - Applied Herbert Xu's patch setting source/destination port numbers. | |
2730 | ||
2731 | - Reapplied one of Herbert Xu's NAT-Traversal patches which got | |
2732 | lost during the migration from SuperFreeS/WAN. | |
b6b90b68 | 2733 | |
997358a6 MW |
2734 | - Fixed a deadlock in the use of the lock_certs_and_keys() mutex. |
2735 | ||

2739 | |
2740 | strongswan-2.1.5 | |
2741 | ---------------- | |
2742 | ||
2743 | - Thomas Walpuski made me aware of a potential DoS attack via | |
2744 | a PKCS#7-wrapped certificate bundle which could overwrite valid CA | |
2745 | certificates in Pluto's authority certificate store. This vulnerability | |
2746 | was fixed by establishing trust in CA candidate certificates up to a | |
2747 | trusted root CA prior to insertion into Pluto's chained list. | |
2748 | ||
2749 | - replaced the --assign option by the -v option in the auto awk script | |
2750 | in order to make it run with mawk under debian/woody. | |
2751 | ||
2752 | ||
2753 | strongswan-2.1.4 | |
2754 | ---------------- | |
2755 | ||
2756 | - Split of the status information between ipsec auto --status (concise) | |
2757 | and ipsec auto --statusall (verbose). Both commands can be used with | |
2758 | an optional connection selector: | |
2759 | ||
2760 | ipsec auto --status[all] <connection_name> | |
2761 | ||
2762 | - Added the description of X.509 related features to the ipsec_auto(8) | |
2763 | man page. | |
2764 | ||
2765 | - Hardened the ASN.1 parser in debug mode, especially the printing | |
2766 | of malformed distinguished names. | |
2767 | ||
2768 | - The size of an RSA public key received in a certificate is now restricted to | |
2769 | ||
2770 | 512 bits <= modulus length <= 8192 bits. | |
2771 | ||
2772 | - Fixed the debug mode enumeration. | |
2773 | ||
2774 | ||
2775 | strongswan-2.1.3 | |
2776 | ---------------- | |
2777 | ||
2778 | - Fixed another PKCS#7 vulnerability which could lead to an | |
2779 | endless loop while following the X.509 trust chain. | |
b6b90b68 | 2780 | |
997358a6 MW |
2781 | |
2782 | strongswan-2.1.2 | |
2783 | ---------------- | |
2784 | ||
2785 | - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski | |
2786 | that accepted end certificates having identical issuer and subject | |
2787 | distinguished names in a multi-tier X.509 trust chain. | |
b6b90b68 | 2788 | |
997358a6 MW |
2789 | |
2790 | strongswan-2.1.1 | |
2791 | ---------------- | |
2792 | ||
2793 | - Removed all remaining references to ipsec_netlink.h in KLIPS. | |
2794 | ||
2795 | ||
2796 | strongswan-2.1.0 | |
2797 | ---------------- | |
2798 | ||
2799 | - The new "ca" section allows to define the following parameters: | |
2800 | ||
2801 | ca kool | |
2802 | cacert=koolCA.pem # cacert of kool CA | |
2803 | ocspuri=http://ocsp.kool.net:8001 # ocsp server | |
2804 | ldapserver=ldap.kool.net # default ldap server | |
2805 | crluri=http://www.kool.net/kool.crl # crl distribution point | |
2806 | crluri2="ldap:///O=Kool, C= .." # crl distribution point #2 | |
2807 | auto=add # add, ignore | |
b6b90b68 | 2808 | |
997358a6 | 2809 | The ca definitions can be monitored via the command |
b6b90b68 | 2810 | |
997358a6 MW |
2811 | ipsec auto --listcainfos |
2812 | ||
2813 | - Fixed cosmetic corruption of /proc filesystem by integrating | |
2814 | D. Hugh Redelmeier's freeswan-2.06 kernel fixes. | |
2815 | ||
2816 | ||
2817 | strongswan-2.0.2 | |
2818 | ---------------- | |
2819 | ||
2820 | - Added support for the 818043 NAT-Traversal update of Microsoft's | |
2821 | Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode. | |
b6b90b68 MW |
2822 | |
2823 | - A symbolic link to libcrypto is now added in the kernel sources | |
997358a6 | 2824 | during kernel compilation |
b6b90b68 | 2825 | |
997358a6 MW |
2826 | - Fixed a couple of 64 bit issues (mostly casts to int). |
2827 | Thanks to Ken Bantoft who checked my sources on a 64 bit platform. | |
2828 | ||
2829 | - Replaced s[n]printf() statements in the kernel by ipsec_snprintf(). | |
2830 | Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro | |
2831 | of the FreeS/WAN team who solved this problem with the 2.4.25 kernel. | |
2832 | ||
2833 | ||
2834 | strongswan-2.0.1 | |
2835 | ---------------- | |
2836 | ||
2837 | - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName | |
2838 | certificate extension which contains no generalName item) can cause | |
2839 | a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has | |
2840 | been hardened to make it more robust against malformed ASN.1 objects. | |
2841 | ||
2842 | - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native | |
2843 | Linux 2.6 IPsec stack. | |
