1 | strongswan-5.9.2 |
2 | ---------------- | |
3 | ||
d65d4eab TB |
4 | - Together with a Linux 5.8 kernel supporting the IMA measurement of the GRUB |
5 | bootloader and the Linux kernel, the strongSwan Attestation IMC allows to do | |
6 | remote attestation of the complete boot phase. A recent TPM 2.0 device with a | |
7 | SHA-256 PCR bank is required, so that both BIOS and IMA file measurements are | |
8 | based on SHA-256 hashes. | |
9 | ||
10 | - Our own TLS library (libtls) that we use for TLS-based EAP methods and PT-TLS | |
11 | gained experimental support for TLS 1.3. Thanks to Méline Sieber (client) and | |
12 | Pascal Knecht (client and server) for their work on this. | |
13 | Because the use of TLS 1.3 with these EAP methods is not yet standardized (two | |
14 | Internet-Drafts are being worked on), the default maximum version is currently | |
356f8735 AS |
15 | set to TLS 1.2, which is now also the default minimum version. However the TNC |
16 | test scenarios using PT-TLS transport already use TLS 1.3. | |
d65d4eab TB |
17 | |
18 | - Other improvements for libtls also affect older TLS versions. For instance, we | |
19 | added support for ECDH with Curve25519/448 (DH groups may also be configured | |
20 | now), for EdDSA keys and certificates and for RSA-PSS signatures. Support for | |
21 | old and weak cipher suites has been removed (e.g. with 3DES and MD5) as well | |
22 | as signature schemes with SHA-1. | |
23 | ||
24 | - The listener_t::ike_update event is now also called for MOBIKE updates. Its | |
25 | signature has changed so we only have to call it once if both addresses/ports | |
26 | have changed (e.g. for an address family switch). The event is now also | |
27 | exposed via vici. | |
28 | ||
29 | - The farp plugin has been ported to macOS and FreeBSD. Thanks to Dan James for | |
30 | working on this. | |
31 | ||
32 | - To fix DNS server installation with systemd-resolved, charon-nm now creates a | |
33 | dummy TUN device again (was removed with 5.5.1). | |
34 | ||
35 | - The botan plugin can use rng_t implementations provided by other plugins when | |
36 | generating keys etc. if the Botan library supports it. | |
37 | ||
38 | - charon-tkm now supports multiple CAs and is configured via vici/swanctl. | |
39 | ||
40 | - Simple glob patterns (e.g. include conf.d/*.conf) now also work on Windows. | |
41 | Handling of forward slashes in paths on Windows has also been improved. | |
42 | ||
43 | - The abbreviations for the 'surname' and 'serial number' RDNs in ASN.1 DNs have | |
44 | been changed to align with RFC 4519: The abbreviation for 'surname' is now | |
45 | "SN" (was "S" before), which was previously used for 'serial number' that can | |
46 | now be specified as "serialNumber" only. | |
47 | ||
48 | - An issue with Windows clients requesting previous IPv6 but not IPv4 virtual | |
49 | IP addresses has been fixed. | |
50 | ||
51 | - ike_sa_manager_t: Checking out IKE_SAs by config is now atomic (e.g. when | |
52 | acquires for different children of the same connection arrive concurrently). | |
53 | The checkout_new() method has been renamed to create_new(). A new | |
54 | checkout_new() method allows registering a new IKE_SA with the manager before | |
55 | checking it in, so jobs can be queued without losing them as they can block | |
56 | on checking out the new SA. | |

59 | strongswan-5.9.1 |
60 | ---------------- | |
61 | ||
dff243a1 TB |
62 | - Remote attestation via TNC supports the SHA-256 based TPM 2.0 BIOS/EFI |
63 | measurements introduced with the Linux 5.4 kernel. | |
64 | ||
65 | - Nonces in OCSP responses are not enforced anymore and only validated if a | |
66 | nonce is actually contained. | |
67 | ||
68 | - Fixed an issue when only some fragments of a retransmitted IKEv2 message were | |
69 | received, which prevented processing a following fragmented message. | |
70 | ||
71 | - All queued vici messages are now sent to subscribed clients during shutdown, | |
72 | which includes ike/child-updown events triggered when all SAs are deleted. | |
73 | ||
74 | - CHILD_SA IP addresses are updated before installation to allow MOBIKE updates | |
75 | while retransmitting a CREATE_CHILD_SA request. | |
76 | ||
77 | - When looking for a route to the peer, the kernel-netlink plugin ignores the | |
78 | current source address if it's deprecated. | |
79 | ||
80 | - The file and syslog loggers support logging the log level of each message | |
81 | after the subsystem (e.g. [IKE2]). | |
82 | ||
83 | - charon-nm is now properly terminated during system shutdown. | |
84 | ||
85 | - Improved support for EdDSA keys in vici/swanctl, in particular, encrypted | |
86 | keys are now supported. | |
87 | ||
88 | - A new global strongswan.conf option allows sending the Cisco FlexVPN vendor ID | |
89 | to prevent Cisco devices from narrowing a 0.0.0.0/0 traffic selector. | |
90 | ||
91 | - The openssl plugin accepts CRLs issued by non-CA certificates if they contain | |
92 | the cRLSign keyUsage flag (the x509 plugin already does this since 4.5.1). | |
93 | ||
94 | - Attributes in PKCS#7 containers, as used in SCEP, are now properly | |
95 | DER-encoded, i.e. sorted. | |
96 | ||
97 | - The load-tester plugin now supports virtual IPv6 addresses and IPv6 source | |
98 | address pools. | |

101 | strongswan-5.9.0 |
102 | ---------------- | |
103 | ||
ce5f9b83 TB |
104 | - We prefer AEAD algorithms for ESP and therefore put AES-GCM in a default AEAD |
105 | proposal in front of the previous default proposal. | |
106 | ||
107 | - The NM backend now clears cached credentials when disconnecting, has DPD and | |
108 | and close action set to restart, and supports custom remote TS via 'remote-ts' | |
109 | option (no GUI support). | |
110 | ||
111 | - The pkcs11 plugin falls back to software hashing for PKCS#1v1.5 RSA signatures | |
112 | if mechanisms with hashing (e.g. CKM_SHA256_RSA_PKCS) are not supported. | |
113 | ||
114 | - The owner/group of log files is now set so the daemon can reopen them if the | |
115 | config is reloaded and it doesn't run as root. | |
116 | ||
117 | - The wolfssl plugin (with wolfSSL 4.4.0+) supports x448 DH and Ed448 keys. | |
118 | ||
119 | - The vici plugin stores all CA certificates in one location, which avoids | |
120 | issues with unloading authority sections or clearing all credentials. | |
121 | ||
122 | - When unloading a vici connection with start_action=start, any related IKE_SAs | |
123 | without children are now terminated (including those in CONNECTING state). | |
124 | ||
125 | - The hashtable implementation has been changed so it maintains insertion order. | |
126 | This was mainly done so the vici plugin can store its connections in a | |
127 | hashtable, which makes managing high numbers of connections faster. | |
128 | ||
129 | - The default maximum size for vici messages (512 KiB) can now be changed via | |
130 | VICI_MESSAGE_SIZE_MAX compile option. | |
131 | ||
132 | - The charon.check_current_path option allows forcing a DPD exchange to check if | |
133 | the current path still works whenever interface/address-changes are detected. | |
134 | ||
135 | - It's possible to use clocks other than CLOCK_MONOTONIC (e.g. CLOCK_BOOTTIME) | |
136 | via TIME_CLOCK_ID compile option if clock_gettime() is available and | |
137 | pthread_condattr_setclock() supports that clock. | |
138 | ||
139 | - Test cases and functions can now be filtered when running the unit tests. | |

142 | strongswan-5.8.4 |
143 | ---------------- | |
144 | ||
145 | - In IKEv1 Quick Mode make sure that a proposal exists before determining | |
146 | lifetimes (fixes crash due to null pointer exception). | |
147 | ||
148 | - OpenSSL currently doesn't support squeezing bytes out of a SHAKE128/256 | |
149 | XOF (eXtended Output Function) multiple times. Unfortunately, | |
150 | EVP_DigestFinalXOF() completely resets the context and later calls not | |
151 | simply fail, they cause a null-pointer dereference in libcrypto. This | |
152 | fixes the crash at the cost of repeating initializing the whole state | |
153 | and allocating too much data for subsequent calls. | |
154 | ||
155 | ||
298c389b TB |
156 | strongswan-5.8.3 |
157 | ---------------- | |
158 | ||
159 | - Updates for the NM backend (and plugin), among others: EAP-TLS authentication, | |
160 | configurable local and remote IKE identities, custom server port, redirection | |
161 | and reauthentication support. | |
162 | ||
163 | - Previously used reqids are now reallocated to workaround an issue on FreeBSD | |
164 | where the daemon can't use reqids > 16383. | |
165 | ||
166 | - On Linux, throw type routes are installed for passthrough policies. They act | |
167 | as fallbacks on routes in other tables and require less information, so they | |
168 | can be installed earlier and are not affected by updates. | |
169 | ||
170 | - For IKEv1, the lifetimes of the selected transform are returned to the | |
171 | initiator, which is an issue with peers that propose different lifetimes in | |
172 | different transforms. We also return the correct transform and proposal IDs. | |
173 | ||
174 | - IKE_SAs are not re-established anymore if a deletion has been queued. | |
175 | ||
176 | - Added support for Ed448 keys and certificates via openssl plugin and pki tool. | |
177 | The openssl plugin also supports SHA-3 and SHAKE128/256. | |
178 | ||
179 | - The use of algorithm IDs from the private use ranges can now be enabled | |
180 | globally, to use them even if no strongSwan vendor ID was exchanged. | |
181 | ||
182 | ||

183 | strongswan-5.8.2 |
184 | ---------------- | |
185 | ||
174bfe51 TB |
186 | - Identity-based CA constraints are supported via vici/swanctl.conf. They |
187 | enforce that the remote's certificate chain contains a CA certificate with a | |
188 | specific identity. While similar to the existing CA constraints, they don't | |
189 | require that the CA certificate is locally installed such as intermediate CA | |
190 | certificates received from peers. Compared to wildcard identity matching (e.g. | |
191 | "..., OU=Research, CN=*") this requires less trust in the intermediate CAs (to | |
192 | only issue certificates with legitimate subject DNs) as long as path length | |
193 | basic constraints prevent them from issuing further intermediate CAs. | |
194 | ||
195 | - Intermediate CA certificates may now be sent in hash-and-URL encoding by | |
196 | configuring a base URL for the parent CA. | |
197 | ||
ccaedf87 AS |
198 | - Implemented NIST SP-800-90A Deterministic Random Bit Generator (DRBG) |
199 | based on AES-CTR and SHA2-HMAC modes. Currently used by gmp and ntru plugins. | |
200 | ||
174bfe51 TB |
201 | - Random nonces sent in an OCSP requests are now expected in the corresponding |
202 | OCSP responses. | |
203 | ||
204 | - The kernel-netlink plugin ignores deprecated IPv6 addresses for MOBIKE. | |
205 | Whether temporary or permanent IPv6 addresses are included depends on the | |
206 | charon.prefer_temporary_addrs setting. | |
207 | ||
208 | - Extended Sequence Numbers (ESN) are configured via PF_KEY if supported by the | |
209 | kernel. | |
210 | ||
211 | - Unique section names are used for CHILD_SAs in vici child-updown events and | |
212 | more information (e.g. statistics) are included for individually deleted | |
213 | CHILD_SAs (in particular for IKEv1). | |
214 | ||
215 | - So fallbacks to other plugins work properly, creating HMACs via openssl plugin | |
216 | now fails instantly if the underlying hash algorithm isn't supported (e.g. | |
217 | MD5 in FIPS-mode). | |
218 | ||
219 | - Exponents of RSA keys read from TPM 2.0 via SAPI are now correctly converted. | |
220 | ||
221 | - Routing table IDs > 255 are supported for custom routes on Linux. | |
222 | ||
223 | - The D-Bus config file for charon-nm is now installed in | |
224 | $(datadir)/dbus-1/system.d instead of $(sysconfdir)/dbus-1/system.d. | |
225 | ||
226 | - INVALID_MAJOR_VERSION notifies are now correctly sent in messages of the same | |
227 | exchange type and using the same message ID as the request. | |
228 | ||
229 | - IKEv2 SAs are immediately destroyed when sending or receiving INVALID_SYNTAX | |
230 | notifies in authenticated messages. | |
231 | ||

82cd511c TB |
233 | strongswan-5.8.1 |
234 | ---------------- | |
235 | ||
236 | - RDNs in Distinguished Names can now optionally be matched less strict. The | |
237 | global option charon.rdn_matching takes two alternative values that cause the | |
238 | matching algorithm to either ignore the order of matched RDNs or additionally | |
239 | accept DNs that contain more RDNs than configured (unmatched RDNs are treated | |
240 | like wildcard matches). | |
241 | ||
242 | - The updown plugin now passes the same interface to the script that is also | |
243 | used for the automatically installed routes, i.e. the interface over which the | |
244 | peer is reached instead of the interface on which the local address is found. | |
245 | ||
246 | - TPM 2.0 contexts are now protected by a mutex to prevent issues if multiple | |
247 | IKE_SAs use the same private key concurrently. | |
248 | ||
249 | ||
08a73261 AS |
250 | strongswan-5.8.0 |
251 | ---------------- | |
252 | ||
23ff1055 TB |
253 | - The systemd service units have been renamed. The modern unit, which was called |
254 | strongswan-swanctl, is now called strongswan (the previous name is configured | |
255 | as alias). The legacy unit is now called strongswan-starter. | |
256 | ||
257 | - Support for XFRM interfaces (available since Linux 4.19) has been added. | |
258 | Configuration is possible via swanctl.conf. Interfaces may be created | |
259 | dynamically via updown/vici scripts, or statically before or after | |
260 | establishing the SAs. Routes must be added manually as needed (the daemon will | |
261 | not install any routes for outbound policies with an interface ID). | |
262 | ||
263 | - Initiation of childless IKE_SAs is supported (RFC 6023). If enabled and | |
264 | supported by the responder, no CHILD_SA is established during IKE_AUTH. This | |
265 | allows using a separate DH exchange even for the first CHILD_SA, which is | |
266 | otherwise created with keys derived from the IKE_SA's key material. | |
267 | ||
268 | - The NetworkManager backend and plugin support IPv6. | |
269 | ||
270 | - The new wolfssl plugin is a wrapper around the wolfSSL crypto library. Thanks | |
271 | to Sean Parkinson of wolfSSL Inc. for the initial patch. | |
272 | ||
273 | - IKE SPIs may optionally be labeled via the charon.spi_mask|label options. This | |
274 | feature was extracted from charon-tkm, however, now applies the mask/label in | |
275 | network order. | |
276 | ||
08a73261 AS |
277 | - The openssl plugin supports ChaCha20-Poly1305 when built with OpenSSL 1.1.0. |
278 | ||
6fcb3baa AS |
279 | - The PB-TNC finite state machine according to section 3.2 of RFC 5793 was not |
280 | correctly implemented when sending either a CRETRY or SRETRY batch. These | |
281 | batches can only be sent in the "Decided" state and a CRETRY batch can | |
282 | immediately carry all messages usually transported by a CDATA batch. It is | |
283 | currently not possible to send a SRETRY batch since full-duplex mode for | |
284 | PT-TLS transport is not supported. | |
285 | ||
23ff1055 TB |
286 | - Instead of marking virtual IPv6 addresses as deprecated, the kernel-netlink |
287 | plugin uses address labels to avoid their use for non-VPN traffic. | |
288 | ||
289 | - The agent plugin creates sockets to the ssh/gpg-agent dynamically and does not | |
290 | keep them open, which otherwise can prevent the agent from getting terminated. | |
291 | ||
292 | - To avoid broadcast loops the forecast plugin now only reinjects packets that | |
293 | are marked or received from the configured interface. | |
294 | ||
295 | - UTF-8 encoded passwords are supported via EAP-MSCHAPv2, which internally uses | |
296 | an UTF-16LE encoding to calculate the NT hash. | |
297 | ||
74ac0c9e AS |
298 | - Adds the build-certs script to generate the keys and certificates used for |
299 | regression tests dynamically. They are built with the pki version installed | |
300 | in the KVM root image so it's not necessary to have an up-to-date version with | |
301 | all required plugins installed on the host system. | |
302 | ||

d1acfeec TB |
304 | strongswan-5.7.2 |
305 | ---------------- | |
306 | ||
307 | - Private key implementations may optionally provide a list of supported | |
308 | signature schemes, which is used by the tpm plugin because for each key on a | |
309 | TPM 2.0 the hash algorithm and for RSA also the padding scheme is predefined. | |
310 | ||
311 | - For RSA with PSS padding, the TPM 2.0 specification mandates the maximum salt | |
312 | length (as defined by the length of the key and hash). However, if the TPM is | |
313 | FIPS-168-4 compliant, the salt length equals the hash length. This is assumed | |
314 | for FIPS-140-2 compliant TPMs, but if that's not the case, it might be | |
315 | necessary to manually enable charon.plugins.tpm.fips_186_4 if the TPM doesn't | |
316 | use the maximum salt length. | |
317 | ||
d1e58e11 TB |
318 | - swanctl now accesses directories for credentials relative to swanctl.conf, in |
319 | particular, when it's loaded from a custom location via --file argument. The | |
320 | base directory that's used if --file is not given is configurable at runtime | |
321 | via SWANCTL_DIR environment variable. | |
322 | ||
323 | - With RADIUS Accounting enabled, the eap-radius plugin adds the session ID to | |
324 | Access-Request messages, simplifying associating database entries for IP | |
325 | leases and accounting with sessions. | |
326 | ||
327 | - IPs assigned by RADIUS servers are included in Accounting-Stop even if clients | |
328 | don't claim them, allowing releasing them early on connection errors. | |
329 | ||
330 | - Selectors installed on transport mode SAs by the kernel-netlink plugin are | |
331 | updated on IP address changes (e.g. via MOBIKE). | |
332 | ||
d1acfeec TB |
333 | - Added support for RSA signatures with SHA-256 and SHA-512 to the agent plugin. |
334 | For older versions of ssh/gpg-agent that only support SHA-1, IKEv2 signature | |
335 | authentication has to be disabled via charon.signature_authentication. | |
336 | ||
337 | - The sshkey and agent plugins support Ed25519/Ed448 SSH keys and signatures. | |
338 | ||
d1e58e11 TB |
339 | - The openssl plugin supports X25519/X448 Diffie-Hellman and Ed25519/Ed448 keys |
340 | and signatures when built against OpenSSL 1.1.1. | |
341 | ||
0e80eb23 | 342 | - Ed25519, ChaCha20/Poly1305, SHA-3 and AES-CCM were added to the botan plugin. |
d1acfeec TB |
343 | |
344 | - The mysql plugin now properly handles database connections with transactions | |
345 | under heavy load. | |
346 | ||
d1e58e11 TB |
347 | - IP addresses in HA pools are now distributed evenly among all segments. |
348 | ||
349 | - On newer FreeBSD kernels, the kernel-pfkey plugin reads the reqid directly | |
350 | from SADB_ACQUIRE messages, i.e. not requiring previous policy installation by | |
351 | the plugin, e.g. for compatibility with if_ipsec(4) VTIs. | |

354 | strongswan-5.7.1 |
355 | ---------------- | |
356 | ||
357 | - Fixes a vulnerability in the gmp plugin triggered by crafted certificates with | |
358 | RSA keys with very small moduli. When verifying signatures with such keys, | |
359 | the code patched with the fix for CVE-2018-16151/2 caused an integer underflow | |
360 | and subsequent heap buffer overflow that results in a crash of the daemon. | |
361 | The vulnerability has been registered as CVE-2018-17540. | |
362 | ||
363 | ||

364 | strongswan-5.7.0 |
365 | ---------------- | |
366 | ||
86c18851 TB |
367 | - Fixes a potential authorization bypass vulnerability in the gmp plugin that |
368 | was caused by a too lenient verification of PKCS#1 v1.5 signatures. Several | |
369 | flaws could be exploited by a Bleichenbacher-style attack to forge signatures | |
370 | for low-exponent keys (i.e. with e=3). CVE-2018-16151 has been assigned to | |
371 | the problem of accepting random bytes after the OID of the hash function in | |
372 | such signatures, and CVE-2018-16152 has been assigned to the issue of not | |
b3ab7a48 | 373 | verifying that the parameters in the ASN.1 algorithmIdentifier structure is |
86c18851 TB |
374 | empty. Other flaws that don't lead to a vulnerability directly (e.g. not |
375 | checking for at least 8 bytes of padding) have no separate CVE assigned. | |
376 | ||
d2a1834d TB |
377 | - Dots are not allowed anymore in section names in swanctl.conf and |
378 | strongswan.conf. This mainly affects the configuration of file loggers. If the | |
379 | path for such a log file contains dots it now has to be configured in the new | |
380 | `path` setting within the arbitrarily renamed subsection in the `filelog` | |
381 | section. | |
382 | ||
383 | - Sections in swanctl.conf and strongswan.conf may now reference other sections. | |
384 | All settings and subsections from such a section are inherited. This allows | |
385 | to simplify configs as redundant information has only to be specified once | |
386 | and may then be included in other sections (refer to the example in the man | |
387 | page for strongswan.conf). | |
388 | ||
389 | - The originally selected IKE config (based on the IPs and IKE version) can now | |
390 | change if no matching algorithm proposal is found. This way the order | |
391 | of the configs doesn't matter that much anymore and it's easily possible to | |
392 | specify separate configs for clients that require weak algorithms (instead | |
393 | of having to also add them in other configs that might be selected). | |
394 | ||
395 | - Support for Postquantum Preshared Keys for IKEv2 (draft-ietf-ipsecme-qr-ikev2) | |
396 | has been added. | |
397 | ||
398 | - The new botan plugin is a wrapper around the Botan C++ crypto library. It | |
399 | requires a fairly recent build from Botan's master branch (or the upcoming | |
400 | 2.8.0 release). Thanks to René Korthaus and his team from Rohde & Schwarz | |
401 | Cybersecurity for the initial patch. | |

407 | for PA-TNC". SWIMA subscription option sets CLOSE_WRITE trigger on apt |
408 | history.log file resulting in a ClientRetry PB-TNC batch to initialize | |
409 | a new measurement cycle. | |
2a26566e | 410 | |
711e0bdb AS |
411 | - Added support for fuzzing the PA-TNC (RFC 5792) and PB-TNC (RFC 5793) NEA |
412 | protocols on Google's OSS-Fuzz infrastructure. | |
413 | ||
041efa6e AS |
414 | - Support for version 2 of Intel's TPM2-TSS TGC Software Stack. The presence of |
415 | the in-kernel /dev/tpmrm0 resource manager is automatically detected. | |
9a7a9623 | 416 | |
d2a1834d TB |
417 | - Marks the in- and/or outbound SA should apply to packets after processing may |
418 | be configured in swanctl.conf on Linux. For outbound SAs this requires at | |
419 | least a 4.14 kernel. Setting a mask and configuring a mark/mask for inbound | |
420 | SAs will be added with the upcoming 4.19 kernel. | |
421 | ||
422 | - New options in swanctl.conf allow configuring how/whether DF, ECN and DS | |
423 | fields in the IP headers are copied during IPsec processing. Controlling this | |
424 | is currently only possible on Linux. | |
425 | ||
426 | - To avoid conflicts, the dhcp plugin now only uses the DHCP server port if | |
427 | explicitly configured. | |
428 | ||

7f14feff TB |
430 | strongswan-5.6.3 |
431 | ---------------- | |
432 | ||
64f7fd92 TB |
433 | - Fixed a DoS vulnerability in the IKEv2 key derivation if the openssl plugin is |
434 | used in FIPS mode and HMAC-MD5 is negotiated as PRF. | |
435 | This vulnerability has been registered as CVE-2018-10811. | |
436 | ||
437 | - Fixed a vulnerability in the stroke plugin, which did not check the received | |
7f14feff TB |
438 | length before reading a message from the socket. Unless a group is configured, |
439 | root privileges are required to access that socket, so in the default | |
440 | configuration this shouldn't be an issue. | |
441 | This vulnerability has been registered as CVE-2018-5388. | |
442 | ||
443 | ⁻ CRLs that are not yet valid are now ignored to avoid problems in scenarios | |
444 | where expired certificates are removed from CRLs and the clock on the host | |
445 | doing the revocation check is trailing behind that of the host issuing CRLs. | |
446 | ||
447 | - The issuer of fetched CRLs is now compared to the issuer of the checked | |
448 | certificate. | |
449 | ||
0d0c8f7d TB |
450 | - CRL validation results other than revocation (e.g. a skipped check because |
451 | the CRL couldn't be fetched) are now stored also for intermediate CA | |
452 | certificates and not only for end-entity certificates, so a strict CRL policy | |
453 | can be enforced in such cases. | |
7f14feff TB |
454 | |
455 | - In compliance with RFC 4945, section 5.1.3.2, certificates used for IKE must | |
456 | now either not contain a keyUsage extension (like the ones generated by pki) | |
0d0c8f7d | 457 | or have at least one of the digitalSignature or nonRepudiation bits set. |
7f14feff TB |
458 | |
459 | - New options for vici/swanctl allow forcing the local termination of an IKE_SA. | |
460 | This might be useful in situations where it's known the other end is not | |
0d0c8f7d TB |
461 | reachable anymore, or that it already removed the IKE_SA, so retransmitting a |
462 | DELETE and waiting for a response would be pointless. Waiting only a certain | |
463 | amount of time for a response before destroying the IKE_SA is also possible | |
464 | by additionally specifying a timeout. | |
7f14feff TB |
465 | |
466 | - When removing routes, the kernel-netlink plugin now checks if it tracks other | |
467 | routes for the same destination and replaces the installed route instead of | |
468 | just removing it. Same during installation, where existing routes previously | |
469 | weren't replaced. This should allow using traps with virtual IPs on Linux. | |
470 | ||
471 | - The dhcp plugin only sends the client identifier option if identity_lease is | |
0d0c8f7d TB |
472 | enabled. It can also send identities of up to 255 bytes length, instead of |
473 | the previous 64 bytes. If a server address is configured, DHCP requests are | |
474 | now sent from port 67 instead of 68 to avoid ICMP port unreachables. | |
7f14feff TB |
475 | |
476 | - Roam events are now completely ignored for IKEv1 SAs. | |
477 | ||
478 | - ChaCha20/Poly1305 is now correctly proposed without key length. For | |
479 | compatibility with older releases the chacha20poly1305compat keyword may be | |
480 | included in proposals to also propose the algorithm with a key length. | |
481 | ||
482 | - Configuration of hardware offload of IPsec SAs is now more flexible and allows | |
0d0c8f7d | 483 | a new mode, which automatically uses it if the kernel and device support it. |
7f14feff TB |
484 | |
485 | - SHA-2 based PRFs are supported in PKCS#8 files as generated by OpenSSL 1.1. | |
486 | ||
487 | - The pki --verify tool may load CA certificates and CRLs from directories. | |
488 | ||
489 | - Fixed an issue with DNS servers passed to NetworkManager in charon-nm. | |
490 | ||
491 | ||
4f60b72a AS |
492 | strongswan-5.6.2 |
493 | ---------------- | |
494 | ||
b640afdb TB |
495 | - Fixed a DoS vulnerability in the parser for PKCS#1 RSASSA-PSS signatures that |
496 | was caused by insufficient input validation. One of the configurable | |
497 | parameters in algorithm identifier structures for RSASSA-PSS signatures is the | |
498 | mask generation function (MGF). Only MGF1 is currently specified for this | |
499 | purpose. However, this in turn takes itself a parameter that specifies the | |
500 | underlying hash function. strongSwan's parser did not correctly handle the | |
501 | case of this parameter being absent, causing an undefined data read. | |
502 | This vulnerability has been registered as CVE-2018-6459. | |
503 | ||
c65bec51 TB |
504 | - The previously negotiated DH group is reused when rekeying an SA, instead of |
505 | using the first group in the configured proposals, which avoids an additional | |
506 | exchange if the peer selected a different group via INVALID_KE_PAYLOAD when | |
507 | the SA was created initially. | |
508 | The selected DH group is also moved to the front of all sent proposals that | |
509 | contain it and all proposals that don't are moved to the back in order to | |
510 | convey the preference for this group to the peer. | |
511 | ||
512 | - Handling of MOBIKE task queuing has been improved. In particular, the response | |
513 | to an address update is not ignored anymore if only an address list update or | |
514 | DPD is queued. | |
515 | ||
516 | - The fallback drop policies installed to avoid traffic leaks when replacing | |
517 | addresses in installed policies are now replaced by temporary drop policies, | |
518 | which also prevent acquires because we currently delete and reinstall IPsec | |
519 | SAs to update their addresses. | |
520 | ||
4f60b72a AS |
521 | - Access X.509 certificates held in non-volatile storage of a TPM 2.0 |
522 | referenced via the NV index. | |
523 | ||
5d3eb57c AS |
524 | - Adding the --keyid parameter to pki --print allows to print private keys |
525 | or certificates stored in a smartcard or a TPM 2.0. | |
526 | ||
c65bec51 TB |
527 | - Fixed proposal selection if a peer incorrectly sends DH groups in the ESP |
528 | proposals during IKE_AUTH and also if a DH group is configured in the local | |
529 | ESP proposal and charon.prefer_configured_proposals is disabled. | |
530 | ||
531 | - MSKs received via RADIUS are now padded to 64 bytes to avoid compatibility | |
532 | issues with EAP-MSCHAPv2 and PRFs that have a block size < 64 bytes (e.g. | |
533 | AES-XCBC-PRF-128). | |
534 | ||
344e1b60 AS |
535 | - The tpm_extendpcr command line tool extends a digest into a TPM PCR. |
536 | ||
c65bec51 TB |
537 | - Ported the NetworkManager backend from the deprecated libnm-glib to libnm. |
538 | ||
539 | - The save-keys debugging/development plugin saves IKE and/or ESP keys to files | |
540 | compatible with Wireshark. | |
541 | ||
4f60b72a | 542 | |
d43b84dc AS |
543 | strongswan-5.6.1 |
544 | ---------------- | |
545 | ||
caee751d TB |
546 | - In compliance with RFCs 8221 and 8247 several algorithms were removed from the |
547 | default ESP/AH and IKEv2 proposals, respectively (3DES, Blowfish and MD5 from | |
548 | ESP/AH, MD5 and MODP-1024 from IKEv2). These algorithms may still be used in | |
549 | custom proposals. | |
550 | ||
551 | - Added support for RSASSA-PSS signatures. For backwards compatibility they are | |
552 | not used automatically by default, enable charon.rsa_pss to change that. To | |
553 | explicitly use or require such signatures with IKEv2 signature authentication | |
554 | (RFC 7427), regardless of whether that option is enabled, use ike:rsa/pss... | |
555 | authentication constraints. | |
556 | ||
557 | - The pki tool can optionally sign certificates/CRLs with RSASSA-PSS via the | |
558 | `--rsa-padding pss` option. | |
559 | ||
560 | - The sec-updater tool checks for security updates in dpkg-based repositories | |
d43b84dc | 561 | (e.g. Debian/Ubuntu) and sets the security flags in the IMV policy database |
c80cec2d AS |
562 | accordingly. Additionally for each new package version a SWID tag for the |
563 | given OS and HW architecture is created and stored in the database. | |
564 | Using the sec-updater.sh script template the lookup can be automated | |
565 | (e.g. via an hourly cron job). | |
d43b84dc AS |
566 | |
567 | - The introduction of file versions in the IMV database scheme broke file | |
568 | reference hash measurements. This has been fixed by creating generic product | |
569 | versions having an empty package name. | |
570 | ||
caee751d TB |
571 | - A new timeout option for the systime-fix plugin stops periodic system time |
572 | checks after a while and enforces a certificate verification, closing or | |
573 | reauthenticating all SAs with invalid certificates. | |
574 | ||
575 | - The IKE event counters, previously only available via ipsec listcounters, may | |
576 | now be queried/reset via vici and the new swanctl --counters command. They are | |
577 | provided by the new optional counters plugin. | |
578 | ||
579 | - Class attributes received in RADIUS Access-Accept messages may optionally be | |
580 | added to RADIUS accounting messages. | |
581 | ||
582 | - Inbound marks may optionally be installed on the SA again (was removed with | |
583 | 5.5.2) by enabling the mark_in_sa option in swanctl.conf. | |
584 | ||
d43b84dc | 585 | |

586 | strongswan-5.6.0 |
587 | ---------------- | |
588 | ||
7cc4a92d TB |
589 | - Fixed a DoS vulnerability in the gmp plugin that was caused by insufficient |
590 | input validation when verifying RSA signatures, which requires decryption | |
591 | with the operation m^e mod n, where m is the signature, and e and n are the | |
592 | exponent and modulus of the public key. The value m is an integer between | |
593 | 0 and n-1, however, the gmp plugin did not verify this. So if m equals n the | |
594 | calculation results in 0, in which case mpz_export() returns NULL. This | |
595 | result wasn't handled properly causing a null-pointer dereference. | |
596 | This vulnerability has been registered as CVE-2017-11185. | |
597 | ||
693705c7 | 598 | - New SWIMA IMC/IMV pair implements the "draft-ietf-sacm-nea-swima-patnc" |
f0ae8c17 | 599 | Internet Draft and has been demonstrated at the IETF 99 Prague Hackathon. |
693705c7 | 600 | |
f237bfcb | 601 | - The IMV database template has been adapted to achieve full compliance |
693705c7 AS |
602 | with the ISO 19770-2:2015 SWID tag standard. |
603 | ||
604 | - The sw-collector tool extracts software events from apt history logs | |
605 | and stores them in an SQLite database to be used by the SWIMA IMC. | |
f0ae8c17 AS |
606 | The tool can also generate SWID tags both for installed and removed |
607 | package versions. | |
693705c7 AS |
608 | |
609 | - The pt-tls-client can attach and use TPM 2.0 protected private keys | |
610 | via the --keyid parameter. | |
611 | ||
612 | - libtpmtss supports Intel's TSS2 Architecture Broker and Resource | |
613 | Manager interface (tcti-tabrmd). | |
614 | ||
f237bfcb TB |
615 | - The new eap-aka-3gpp plugin implements the 3GPP MILENAGE algorithms |
616 | in software. K (optionally concatenated with OPc) may be configured as | |
617 | binary EAP secret. | |
618 | ||
619 | - CHILD_SA rekeying was fixed in charon-tkm and was slightly changed: The | |
620 | switch to the new outbound IPsec SA now happens via SPI on the outbound | |
621 | policy on Linux, and in case of lost rekey collisions no outbound SA/policy | |
622 | is temporarily installed for the redundant CHILD_SA. | |
623 | ||
624 | - The new %unique-dir value for mark* settings allocates separate unique marks | |
625 | for each CHILD_SA direction (in/out). | |
626 | ||
693705c7 | 627 | |
d38d1fcd AS |
628 | strongswan-5.5.3 |
629 | ---------------- | |
630 | ||
8622a742 TB |
631 | - Fixed a DoS vulnerability in the gmp plugin that was caused by insufficient |
632 | input validation when verifying RSA signatures. More specifically, | |
633 | mpz_powm_sec() has two requirements regarding the passed exponent and modulus | |
634 | that the plugin did not enforce, if these are not met the calculation will | |
635 | result in a floating point exception that crashes the whole process. | |
636 | This vulnerability has been registered as CVE-2017-9022. | |
637 | ||
638 | - Fixed a DoS vulnerability in the x509 plugin that was caused because the ASN.1 | |
639 | parser didn't handle ASN.1 CHOICE types properly, which could result in an | |
640 | infinite loop when parsing X.509 extensions that use such types. | |
641 | This vulnerability has been registered as CVE-2017-9023. | |
642 | ||
85ee4107 TB |
643 | - The behavior during IKEv2 CHILD_SA rekeying has been changed in order to avoid |
644 | traffic loss. The responder now only installs the new inbound SA and delays | |
645 | installing the outbound SA until it receives the DELETE for the replaced | |
646 | CHILD_SA. Similarly, the inbound SA of the replaced CHILD_SA is not removed | |
647 | for a configurable amount of seconds (charon.delete_rekeyed_delay) after the | |
648 | DELETE has been processed to reduce the chance of dropping delayed packets. | |
649 | ||
650 | - The code base has been ported to Apple's ARM64 iOS platform, whose calling | |
651 | conventions for variadic and regular functions are different. This means | |
652 | assigning non-variadic functions to variadic function pointers does not work. | |
653 | To avoid this issue the enumerator_t interface has been changed and the | |
654 | signatures of the callback functions for enumerator_create_filter(), and the | |
655 | invoke_function() and find_first() methods on linked_list_t have been changed. | |
656 | The return type of find_first() also changed from status_t to bool. | |
657 | ||
658 | - Added support for fuzzing the certificate parser provided by the default | |
659 | plugins (x509, pem, gmp etc.) on Google's OSS-Fuzz infrastructure. Several | |
660 | issues found while fuzzing these plugins were fixed. | |
661 | ||
662 | - Two new options have been added to charon's retransmission settings: | |
663 | retransmit_limit and retransmit_jitter. The former adds an upper limit to the | |
664 | calculated retransmission timeout, the latter randomly reduces it. | |
665 | ||
666 | - A bug in swanctl's --load-creds command was fixed that caused unencrypted | |
667 | private keys to get unloaded if the command was called multiple times. The | |
668 | load-key VICI command now returns the key ID of the loaded key on success. | |
669 | ||
670 | - The credential manager now enumerates local credential sets before global | |
671 | ones. This means certificates supplied by the peer will now be preferred over | |
672 | certificates with the same identity that may be locally stored (e.g. in the | |
673 | certificate cache). | |
674 | ||
675 | - Added support for hardware offload of IPsec SAs as introduced by Linux 4.11 | |
676 | for hardware that supports this. | |
677 | ||
678 | - When building the libraries monolithically and statically the plugin | |
679 | constructors are now hard-coded in each library so the plugin code is not | |
680 | removed by the linker because it thinks none of their symbols are ever | |
681 | referenced. | |
682 | ||
d38d1fcd AS |
683 | - The pki tool loads the curve25519 plugin by default. |
684 | ||
685 | ||
4a979994 AS |
686 | strongswan-5.5.2 |
687 | ---------------- | |
688 | ||
011195f1 AS |
689 | - Support of Diffie-Hellman group 31 using Curve25519 for IKE as defined |
690 | by RFC 8031. | |
691 | ||
65797c9f AS |
692 | - Support of Ed25519 digital signature algorithm for IKEv2 as defined by |
693 | draft-ietf-ipsecme-eddsa. Ed25519-based public key pairs, X.509 certificates | |
694 | and CRLs can be generated and printed by the pki tool. | |
695 | ||
af9341c2 AS |
696 | - The new "tpm" libtpmtss plugin allows to use persistent private RSA and ECDSA |
697 | keys bound to a TPM 2.0 for both IKE and TLS authentication. Using the | |
698 | TPM 2.0 object handle as keyid parameter, the pki --pub tool can extract | |
6885375e AS |
699 | the public key from the TPM thereby replacing the aikpub2 tool. In a similar |
700 | fashion pki --req can generate a PKCS#10 certificate request signed with | |
701 | the TPM private key. | |
af9341c2 | 702 | |
7ae95468 MW |
703 | - The pki tool gained support for generating certificates with the RFC 3779 |
704 | addrblock extension. The charon addrblock plugin now dynamically narrows | |
705 | traffic selectors based on the certificate addrblocks instead of rejecting | |
706 | non-matching selectors completely. This allows generic connections, where | |
707 | the allowed selectors are defined by the used certificates only. | |
708 | ||
e16d1005 | 709 | - In-place update of cached base and delta CRLs does not leave dozens |
4a979994 AS |
710 | of stale copies in cache memory. |
711 | ||
e16d1005 TB |
712 | - Several new features for the VICI interface and the swanctl utility: Querying |
713 | specific pools, enumerating and unloading keys and shared secrets, loading | |
714 | keys and certificates from PKCS#11 tokens, the ability to initiate, install | |
715 | and uninstall connections and policies by their exact name (if multiple child | |
716 | sections in different connections share the same name), a command to initiate | |
717 | the rekeying of IKE and IPsec SAs, support for settings previously only | |
718 | supported by the old config files (plain pubkeys, dscp, certificate policies, | |
719 | IPv6 Transport Proxy Mode, NT Hash secrets, mediation extension). | |
720 | ||
721 | Important: Due to issues with VICI bindings that map sub-sections to | |
722 | dictionaries the CHILD_SA sections returned via list-sas now have a unique | |
723 | name, the original name of a CHILD_SA is returned in the "name" key of its | |
724 | section. | |
725 | ||
4a979994 | 726 | |
8aaa6de3 AS |
727 | strongswan-5.5.1 |
728 | ---------------- | |
729 | ||
730 | - The newhope plugin implements the post-quantum NewHope key exchange algorithm | |
731 | proposed in their 2015 paper by Erdem Alkim, Léo Ducas, Thomas Pöppelmann and | |
732 | Peter Schwabe. | |
733 | ||
e31ed9ab AS |
734 | - The libstrongswan crypto factory now offers the registration of Extended |
735 | Output Functions (XOFs). Currently supported XOFs are SHAKE128 and SHAKE256 | |
736 | implemented by the sha3 plugin, ChaCHa20 implemented by the chapoly plugin | |
737 | and the more traditional MGF1 Mask Generation Functions based on the SHA-1, | |
738 | SHA-256 and SHA-512 hash algorithms implemented by the new mgf1 plugin. | |
739 | ||
e6a4bd83 AS |
740 | - The pki tool, with help of the pkcs1 or openssl plugins, can parse private |
741 | keys in any of the supported formats without having to know the exact type. | |
742 | So instead of having to specify rsa or ecdsa explicitly the keyword priv may | |
743 | be used to indicate a private key of any type. Similarly, swanctl can load | |
744 | any type of private key from the swanctl/private directory. | |
745 | ||
6b3e408b AS |
746 | - The pki tool can handle RSASSA-PKCS1v1.5-with-SHA-3 signatures using the |
747 | sha3 and gmp plugins. | |
748 | ||
e31ed9ab | 749 | - The VICI flush-certs command flushes certificates from the volatile |
8aaa6de3 AS |
750 | certificate cache. Optionally the type of the certificates to be |
751 | flushed (e.g. type = x509_crl) can be specified. | |
752 | ||
a617223e AS |
753 | - Setting cache_crls = yes in strongswan.conf the vici plugin saves regular, |
754 | base and delta CRLs to disk. | |
755 | ||
e6a4bd83 AS |
756 | - IKE fragmentation is now enabled by default with the default fragment size |
757 | set to 1280 bytes for both IP address families. | |
758 | ||
8aaa6de3 AS |
759 | - libtpmtss: In the TSS2 API the function TeardownSocketTcti() was replaced by |
760 | tss2_tcti_finalize(). | |
761 | ||
762 | ||
6a24637d AS |
763 | strongswan-5.5.0 |
764 | ---------------- | |
765 | ||
766 | - The new libtpmtss library offers support for both TPM 1.2 and TPM 2.0 | |
767 | Trusted Platform Modules. This allows the Attestation IMC/IMV pair to | |
768 | do TPM 2.0 based attestation. | |
769 | ||
b977ef8e TB |
770 | - The behavior during IKEv2 exchange collisions has been improved/fixed in |
771 | several corner cases and support for TEMPORARY_FAILURE and CHILD_SA_NOT_FOUND | |
772 | notifies, as defined by RFC 7296, has been added. | |
8fafbffd | 773 | |
b977ef8e TB |
774 | - IPsec policy priorities can be set manually (e.g. for high-priority drop |
775 | policies) and outbound policies may be restricted to a network interface. | |
776 | ||
777 | - The scheme for the automatically calculated default priorities has been | |
778 | changed and now also considers port masks, which were added with 5.4.0. | |
779 | ||
780 | - FWD policies are now installed in both directions in regards to the traffic | |
781 | selectors. Because such "outbound" FWD policies could conflict with "inbound" | |
782 | FWD policies of other SAs they are installed with a lower priority and don't | |
783 | have a reqid set, which allows kernel plugins to distinguish between the two | |
784 | and prefer those with a reqid. | |
785 | ||
786 | - For outbound IPsec SAs no replay window is configured anymore. | |
787 | ||
788 | - Enhanced the functionality of the swanctl --list-conns command by listing | |
789 | IKE_SA and CHILD_SA reauthentication and rekeying settings, and EAP/XAuth | |
790 | identities and EAP types. | |
791 | ||
792 | - DNS servers installed by the resolve plugin are now refcounted, which should | |
793 | fix its use with make-before-break reauthentication. Any output written to | |
794 | stderr/stdout by resolvconf is now logged. | |
795 | ||
796 | - The methods in the kernel interfaces have been changed to take structs instead | |
797 | of long lists of arguments. Similarly the constructors for peer_cfg_t and | |
798 | child_cfg_t now take structs. | |

801 | strongswan-5.4.0 |
802 | ---------------- | |
803 | ||
6fc68343 TB |
804 | - Support for IKEv2 redirection (RFC 5685) has been added. Plugins may |
805 | implement the redirect_provider_t interface to decide if and when to redirect | |
806 | connecting clients. It is also possible to redirect established IKE_SAs based | |
807 | on different selectors via VICI/swanctl. Unless disabled in strongswan.conf | |
808 | the charon daemon will follow redirect requests received from servers. | |
809 | ||
c171afea TB |
810 | - The ike: prefix enables the explicit configuration of signature scheme |
811 | constraints against IKEv2 authentication in rightauth, which allows the use | |
812 | of different signature schemes for trustchain verification and authentication. | |
813 | ||
b4337c5b TB |
814 | - The initiator of an IKEv2 make-before-break reauthentication now suspends |
815 | online certificate revocation checks (OCSP, CRLs) until the new IKE_SA and all | |
816 | CHILD_SAs are established. This is required if the checks are done over the | |
817 | CHILD_SA established with the new IKE_SA. This is not possible until the | |
818 | initiator installs this SA and that only happens after the authentication is | |
819 | completed successfully. So we suspend the checks during the reauthentication | |
820 | and do them afterwards, if they fail the IKE_SA is closed. This change has no | |
821 | effect on the behavior during the authentication of the initial IKE_SA. | |
822 | ||
b5eed58a AS |
823 | - For the vici plugin a Vici:Session Perl CPAN module has been added to allow |
824 | Perl applications to control and/or monitor the IKE daemon using the VICI | |
825 | interface, similar to the existing Python egg or Ruby gem. | |
826 | ||
5c25780c AS |
827 | - Traffic selectors with port ranges can now be configured in the Linux kernel: |
828 | e.g. remote_ts = 10.1.0.0/16[tcp/20-23] local_ts = dynamic[tcp/32768-65535]. | |
829 | The port range must map to a port mask, though since the kernel does not | |
830 | support arbitrary ranges. | |
831 | ||
bebccf98 AS |
832 | - The vici plugin allows the configuration of IPv4 and IPv6 address ranges |
833 | in local and remote traffic selectors. Since both the Linux kernel and | |
834 | iptables cannot handle arbitrary ranges, address ranges are mapped to the next | |
835 | larger CIDR subnet by the kernel-netlink and updown plugins, respectively. | |
836 | ||
837 | - Implemented IKEv1 IPv4/IPv6 address subnet and range identities that can be | |
838 | used as owners of shared secrets. | |

841 | strongswan-5.3.5 |
842 | ---------------- | |
843 | ||
844 | - Properly handle potential EINTR errors in sigwaitinfo(2) calls that replaced | |
845 | sigwait(3) calls with 5.3.4. | |
846 | ||
847 | - RADIUS retransmission timeouts are now configurable, courtesy of Thom Troy. | |

6590298d AS |
850 | strongswan-5.3.4 |
851 | ---------------- | |
852 | ||
453e204a TB |
853 | - Fixed an authentication bypass vulnerability in the eap-mschapv2 plugin that |
854 | was caused by insufficient verification of the internal state when handling | |
855 | MSCHAPv2 Success messages received by the client. | |
856 | This vulnerability has been registered as CVE-2015-8023. | |
857 | ||
6590298d AS |
858 | - The sha3 plugin implements the SHA3 Keccak-F1600 hash algorithm family. |
859 | Within the strongSwan framework SHA3 is currently used for BLISS signatures | |
860 | only because the OIDs for other signature algorithms haven't been defined | |
861 | yet. Also the use of SHA3 for IKEv2 has not been standardized yet. | |
862 | ||
863 | ||
63d37038 AS |
864 | strongswan-5.3.3 |
865 | ---------------- | |
866 | ||
18e0d66b TB |
867 | - Added support for the ChaCha20/Poly1305 AEAD cipher specified in RFC 7539 and |
868 | RFC 7634 using the chacha20poly1305 ike/esp proposal keyword. The new chapoly | |
869 | plugin implements the cipher, if possible SSE-accelerated on x86/x64 | |
870 | architectures. It is usable both in IKEv2 and the strongSwan libipsec ESP | |
871 | backend. On Linux 4.2 or newer the kernel-netlink plugin can configure the | |
872 | cipher for ESP SAs. | |
39660798 | 873 | |
63d37038 | 874 | - The vici interface now supports the configuration of auxiliary certification |
18e0d66b TB |
875 | authority information as CRL and OCSP URIs. |
876 | ||
877 | - In the bliss plugin the c_indices derivation using a SHA-512 based random | |
878 | oracle has been fixed, generalized and standardized by employing the MGF1 mask | |
b3ab7a48 | 879 | generation function with SHA-512. As a consequence BLISS signatures using the |
18e0d66b TB |
880 | improved oracle are not compatible with the earlier implementation. |
881 | ||
882 | - Support for auto=route with right=%any for transport mode connections has | |
883 | been added (the ikev2/trap-any scenario provides examples). | |
884 | ||
885 | - The starter daemon does not flush IPsec policies and SAs anymore when it is | |
886 | stopped. Already existing duplicate policies are now overwritten by the IKE | |
887 | daemon when it installs its policies. | |
888 | ||
889 | - Init limits (like charon.init_limit_half_open) can now optionally be enforced | |
890 | when initiating SAs via VICI. For this, IKE_SAs initiated by the daemon are | |
891 | now also counted as half-open SAs, which, as a side-effect, fixes the status | |
892 | output while connecting (e.g. in ipsec status). | |
893 | ||
894 | - Symmetric configuration of EAP methods in left|rightauth is now possible when | |
895 | mutual EAP-only authentication is used (previously, the client had to | |
896 | configure rightauth=eap or rightauth=any, which prevented it from using this | |
897 | same config as responder). | |
898 | ||
899 | - The initiator flag in the IKEv2 header is compared again (wasn't the case | |
900 | since 5.0.0) and packets that have the flag set incorrectly are again ignored. | |
901 | ||
a215008c | 902 | - Implemented a demo Hardcopy Device IMC/IMV pair based on the "Hardcopy |
453e204a | 903 | Device Health Assessment Trusted Network Connect Binding" (HCD-TNC) |
a215008c AS |
904 | document drafted by the IEEE Printer Working Group (PWG). |
905 | ||
906 | - Fixed IF-M segmentation which failed in the presence of multiple small | |
907 | attributes in front of a huge attribute to be segmented. | |
908 | ||
39660798 | 909 | |
2b19e517 TB |
910 | strongswan-5.3.2 |
911 | ---------------- | |
912 | ||
913 | - Fixed a vulnerability that allowed rogue servers with a valid certificate | |
914 | accepted by the client to trick it into disclosing its username and even | |
915 | password (if the client accepts EAP-GTC). This was caused because constraints | |
916 | against the responder's authentication were enforced too late. | |
917 | This vulnerability has been registered as CVE-2015-4171. | |
918 | ||
919 | ||
eb423ebb AS |
920 | strongswan-5.3.1 |
921 | ---------------- | |
922 | ||
099260d8 TB |
923 | - Fixed a denial-of-service and potential remote code execution vulnerability |
924 | triggered by IKEv1/IKEv2 messages that contain payloads for the respective | |
925 | other IKE version. Such payload are treated specially since 5.2.2 but because | |
926 | they were still identified by their original payload type they were used as | |
927 | such in some places causing invalid function pointer dereferences. | |
928 | The vulnerability has been registered as CVE-2015-3991. | |
929 | ||
e8ba1d47 MW |
930 | - The new aesni plugin provides CBC, CTR, XCBC, CMAC, CCM and GCM crypto |
931 | primitives for AES-128/192/256. The plugin requires AES-NI and PCLMULQDQ | |
932 | instructions and works on both x86 and x64 architectures. It provides | |
933 | superior crypto performance in userland without any external libraries. | |
934 | ||
935 | ||
c6595222 AS |
936 | strongswan-5.3.0 |
937 | ---------------- | |
938 | ||
4a00f912 MW |
939 | - Added support for IKEv2 make-before-break reauthentication. By using a global |
940 | CHILD_SA reqid allocation mechanism, charon supports overlapping CHILD_SAs. | |
941 | This allows the use of make-before-break instead of the previously supported | |
942 | break-before-make reauthentication, avoiding connectivity gaps during that | |
943 | procedure. As the new mechanism may fail with peers not supporting it (such | |
944 | as any previous strongSwan release) it must be explicitly enabled using | |
945 | the charon.make_before_break strongswan.conf option. | |
946 | ||
3f1ef3a6 TB |
947 | - Support for "Signature Authentication in IKEv2" (RFC 7427) has been added. |
948 | This allows the use of stronger hash algorithms for public key authentication. | |
949 | By default, signature schemes are chosen based on the strength of the | |
950 | signature key, but specific hash algorithms may be configured in leftauth. | |
951 | ||
952 | - Key types and hash algorithms specified in rightauth are now also checked | |
953 | against IKEv2 signature schemes. If such constraints are used for certificate | |
954 | chain validation in existing configurations, in particular with peers that | |
955 | don't support RFC 7427, it may be necessary to disable this feature with the | |
956 | charon.signature_authentication_constraints setting, because the signature | |
957 | scheme used in classic IKEv2 public key authentication may not be strong | |
958 | enough. | |
959 | ||
1e1e88e6 MW |
960 | - The new connmark plugin allows a host to bind conntrack flows to a specific |
961 | CHILD_SA by applying and restoring the SA mark to conntrack entries. This | |
962 | allows a peer to handle multiple transport mode connections coming over the | |
963 | same NAT device for client-initiated flows. A common use case is to protect | |
964 | L2TP/IPsec, as supported by some systems. | |
965 | ||
dc88d179 MW |
966 | - The forecast plugin can forward broadcast and multicast messages between |
967 | connected clients and a LAN. For CHILD_SA using unique marks, it sets up | |
968 | the required Netfilter rules and uses a multicast/broadcast listener that | |
969 | forwards such messages to all connected clients. This plugin is designed for | |
970 | Windows 7 IKEv2 clients, which announces its services over the tunnel if the | |
971 | negotiated IPsec policy allows it. | |
972 | ||
2185c29b MW |
973 | - For the vici plugin a Python Egg has been added to allow Python applications |
974 | to control or monitor the IKE daemon using the VICI interface, similar to the | |
975 | existing ruby gem. The Python library has been contributed by Björn Schuberg. | |
976 | ||
f05a578b MW |
977 | - EAP server methods now can fulfill public key constraints, such as rightcert |
978 | or rightca. Additionally, public key and signature constraints can be | |
979 | specified for EAP methods in the rightauth keyword. Currently the EAP-TLS and | |
980 | EAP-TTLS methods provide verification details to constraints checking. | |
981 | ||
27bd0fed AS |
982 | - Upgrade of the BLISS post-quantum signature algorithm to the improved BLISS-B |
983 | variant. Can be used in conjunction with the SHA256, SHA384 and SHA512 hash | |
984 | algorithms with SHA512 being the default. | |
985 | ||
e0359350 AS |
986 | - The IF-IMV 1.4 interface now makes the IP address of the TNC access requestor |
987 | as seen by the TNC server available to all IMVs. This information can be | |
988 | forwarded to policy enforcement points (e.g. firewalls or routers). | |
989 | ||
7b4a96b2 AS |
990 | - The new mutual tnccs-20 plugin parameter activates mutual TNC measurements |
991 | in PB-TNC half-duplex mode between two endpoints over either a PT-EAP or | |
992 | PT-TLS transport medium. | |
993 | ||

995 | strongswan-5.2.2 |
996 | ---------------- | |
997 | ||
919449a3 TB |
998 | - Fixed a denial-of-service vulnerability triggered by an IKEv2 Key Exchange |
999 | payload that contains the Diffie-Hellman group 1025. This identifier was | |
1000 | used internally for DH groups with custom generator and prime. Because | |
1001 | these arguments are missing when creating DH objects based on the KE payload | |
1002 | an invalid pointer dereference occurred. This allowed an attacker to crash | |
1003 | the IKE daemon with a single IKE_SA_INIT message containing such a KE | |
1004 | payload. The vulnerability has been registered as CVE-2014-9221. | |
1005 | ||
045501d5 MW |
1006 | - The left/rightid options in ipsec.conf, or any other identity in strongSwan, |
1007 | now accept prefixes to enforce an explicit type, such as email: or fqdn:. | |
1008 | Note that no conversion is done for the remaining string, refer to | |
1009 | ipsec.conf(5) for details. | |
1010 | ||
30a90ccf | 1011 | - The post-quantum Bimodal Lattice Signature Scheme (BLISS) can be used as |
32d19652 AS |
1012 | an IKEv2 public key authentication method. The pki tool offers full support |
1013 | for the generation of BLISS key pairs and certificates. | |
1014 | ||
30a90ccf TB |
1015 | - Fixed mapping of integrity algorithms negotiated for AH via IKEv1. This could |
1016 | cause interoperability issues when connecting to older versions of charon. | |
1017 | ||
045501d5 | 1018 | |
dcdcae01 MW |
1019 | strongswan-5.2.1 |
1020 | ---------------- | |
1021 | ||
1022 | - The new charon-systemd IKE daemon implements an IKE daemon tailored for use | |
1023 | with systemd. It avoids the dependency on ipsec starter and uses swanctl | |
1024 | as configuration backend, building a simple and lightweight solution. It | |
1025 | supports native systemd journal logging. | |
1026 | ||
55758bec TB |
1027 | - Support for IKEv2 fragmentation as per RFC 7383 has been added. Like IKEv1 |
1028 | fragmentation it can be enabled by setting fragmentation=yes in ipsec.conf. | |
1029 | ||
e9a93cb7 AS |
1030 | - Support of the TCG TNC IF-M Attribute Segmentation specification proposal. |
1031 | All attributes can be segmented. Additionally TCG/SWID Tag, TCG/SWID Tag ID | |
1032 | and IETF/Installed Packages attributes can be processed incrementally on a | |
1033 | per segment basis. | |
1034 | ||
9180c921 MW |
1035 | - The new ext-auth plugin calls an external script to implement custom IKE_SA |
1036 | authorization logic, courtesy of Vyronas Tsingaras. | |
1037 | ||
7431ad0d MW |
1038 | - For the vici plugin a ruby gem has been added to allow ruby applications |
1039 | to control or monitor the IKE daemon. The vici documentation has been updated | |
1040 | to include a description of the available operations and some simple examples | |
1041 | using both the libvici C interface and the ruby gem. | |

1044 | strongswan-5.2.0 |
1045 | ---------------- | |
1046 | ||
4c5e52f5 MW |
1047 | - strongSwan has been ported to the Windows platform. Using a MinGW toolchain, |
1048 | many parts of the strongSwan codebase run natively on Windows 7 / 2008 R2 | |
1049 | and newer releases. charon-svc implements a Windows IKE service based on | |
1050 | libcharon, the kernel-iph and kernel-wfp plugins act as networking and IPsec | |
1051 | backend on the Windows platform. socket-win provides a native IKE socket | |
1052 | implementation, while winhttp fetches CRL and OCSP information using the | |
1053 | WinHTTP API. | |
1054 | ||
4787523c MW |
1055 | - The new vici plugin provides a Versatile IKE Configuration Interface for |
1056 | charon. Using the stable IPC interface, external applications can configure, | |
1057 | control and monitor the IKE daemon. Instead of scripting the ipsec tool | |
1058 | and generating ipsec.conf, third party applications can use the new interface | |
1059 | for more control and better reliability. | |
1060 | ||
b30c09ea MW |
1061 | - Built upon the libvici client library, swanctl implements the first user of |
1062 | the VICI interface. Together with a swanctl.conf configuration file, | |
1063 | connections can be defined, loaded and managed. swanctl provides a portable, | |
1064 | complete IKE configuration and control interface for the command line. | |
73303700 | 1065 | The first six swanctl example scenarios have been added. |
b30c09ea | 1066 | |
6048d773 AS |
1067 | - The SWID IMV implements a JSON-based REST API which allows the exchange |
1068 | of SWID tags and Software IDs with the strongTNC policy manager. | |
1069 | ||
37cb91d7 | 1070 | - The SWID IMC can extract all installed packages from the dpkg (Debian, |
3d2b36b8 TB |
1071 | Ubuntu, Linux Mint etc.), rpm (Fedora, RedHat, OpenSUSE, etc.), or |
1072 | pacman (Arch Linux, Manjaro, etc.) package managers, respectively, using the | |
1073 | swidGenerator (https://github.com/strongswan/swidGenerator) which generates | |
1074 | SWID tags according to the new ISO/IEC 19770-2:2014 standard. | |
37cb91d7 AS |
1075 | |
1076 | - All IMVs now share the access requestor ID, device ID and product info | |
1077 | of an access requestor via a common imv_session object. | |
1078 | ||
9b9d5223 AS |
1079 | - The Attestation IMC/IMV pair supports the IMA-NG measurement format |
1080 | introduced with the Linux 3.13 kernel. | |
1081 | ||
41a4d5a4 AS |
1082 | - The aikgen tool generates an Attestation Identity Key bound to a TPM. |
1083 | ||
03b5def0 | 1084 | - Implemented the PT-EAP transport protocol (RFC 7171) for Trusted Network |
6048d773 | 1085 | Connect. |
03b5def0 | 1086 | |
52d77f32 MW |

1092 | strongswan-5.1.3 |
1093 | ---------------- | |
1094 | ||
e59ce07b TB |
1095 | - Fixed an authentication bypass vulnerability triggered by rekeying an |
1096 | unestablished IKEv2 SA while it gets actively initiated. This allowed an | |
1097 | attacker to trick a peer's IKE_SA state to established, without the need to | |
1098 | provide any valid authentication credentials. The vulnerability has been | |
1099 | registered as CVE-2014-2338. | |
1100 | ||
8101e6aa MW |
1101 | - The acert plugin evaluates X.509 Attribute Certificates. Group membership |
1102 | information encoded as strings can be used to fulfill authorization checks | |
1103 | defined with the rightgroups option. Attribute Certificates can be loaded | |
1104 | locally or get exchanged in IKEv2 certificate payloads. | |
1105 | ||
1106 | - The pki command gained support to generate X.509 Attribute Certificates | |
1107 | using the --acert subcommand, while the --print command supports the ac type. | |
1108 | The openac utility has been removed in favor of the new pki functionality. | |
1109 | ||
7dc7fdea MW |
1110 | - The libtls TLS 1.2 implementation as used by EAP-(T)TLS and other protocols |
1111 | has been extended by AEAD mode support, currently limited to AES-GCM. | |
1112 | ||

1114 | strongswan-5.1.2 |
1115 | ---------------- | |
1116 | ||
c2d5add6 TB |
1117 | - A new default configuration file layout is introduced. The new default |
1118 | strongswan.conf file mainly includes config snippets from the strongswan.d | |
1119 | and strongswan.d/charon directories (the latter containing snippets for all | |
1120 | plugins). The snippets, with commented defaults, are automatically | |
1121 | generated and installed, if they don't exist yet. They are also installed | |
1122 | in $prefix/share/strongswan/templates so existing files can be compared to | |
1123 | the current defaults. | |
1124 | ||
1125 | - As an alternative to the non-extensible charon.load setting, the plugins | |
1126 | to load in charon (and optionally other applications) can now be determined | |
1127 | via the charon.plugins.<name>.load setting for each plugin (enabled in the | |
1128 | new default strongswan.conf file via the charon.load_modular option). | |
1129 | The load setting optionally takes a numeric priority value that allows | |
1130 | reordering the plugins (otherwise the default plugin order is preserved). | |
1131 | ||
1132 | - All strongswan.conf settings that were formerly defined in library specific | |
1133 | "global" sections are now application specific (e.g. settings for plugins in | |
1134 | libstrongswan.plugins can now be set only for charon in charon.plugins). | |
1135 | The old options are still supported, which now allows to define defaults for | |
1136 | all applications in the libstrongswan section. | |
1137 | ||
acc25f29 AS |
1138 | - The ntru libstrongswan plugin supports NTRUEncrypt as a post-quantum |
1139 | computer IKE key exchange mechanism. The implementation is based on the | |
1140 | ntru-crypto library from the NTRUOpenSourceProject. The supported security | |
1141 | strengths are ntru112, ntru128, ntru192, and ntru256. Since the private DH | |
1142 | group IDs 1030..1033 have been assigned, the strongSwan Vendor ID must be | |
1143 | sent (charon.send_vendor_id = yes) in order to use NTRU. | |
1144 | ||
800b361e AS |
1145 | - Defined a TPMRA remote attestation workitem and added support for it to the |
1146 | Attestation IMV. | |

1148 | - Compatibility issues between IPComp (compress=yes) and leftfirewall=yes as |
1149 | well as multiple subnets in left|rightsubnet have been fixed. | |
1150 | ||
572582f5 MW |
1151 | - When enabling its "session" strongswan.conf option, the xauth-pam plugin opens |
1152 | and closes a PAM session for each established IKE_SA. Patch courtesy of | |
1153 | Andrea Bonomi. | |
acc25f29 | 1154 | |
0cec570a MW |
1155 | - The strongSwan unit testing framework has been rewritten without the "check" |
1156 | dependency for improved flexibility and portability. It now properly supports | |
1157 | multi-threaded and memory leak testing and brings a bunch of new test cases. | |
1158 | ||
1159 | ||
2b32884d AS |
1160 | strongswan-5.1.1 |
1161 | ---------------- | |
1162 | ||
7b8fbd74 AS |
1163 | - Fixed a denial-of-service vulnerability and potential authorization bypass |
1164 | triggered by a crafted ID_DER_ASN1_DN ID payload. The cause is an insufficient | |
1165 | length check when comparing such identities. The vulnerability has been | |
1166 | registered as CVE-2013-6075. | |
1167 | ||
1168 | - Fixed a denial-of-service vulnerability triggered by a crafted IKEv1 | |
1169 | fragmentation payload. The cause is a NULL pointer dereference. The | |
1170 | vulnerability has been registered as CVE-2013-6076. | |
1171 | ||
2b32884d | 1172 | - The lean stand-alone pt-tls-client can set up a RFC 6876 PT-TLS session |
1c1ba803 TB |
1173 | with a strongSwan policy enforcement point which uses the tnc-pdp charon |
1174 | plugin. | |
2b32884d | 1175 | |
fa2f6aa1 AS |
1176 | - The new TCG TNC SWID IMC/IMV pair supports targeted SWID requests for either |
1177 | full SWID Tag or concise SWID Tag ID inventories. | |
1178 | ||
38fb8e4e MW |
1179 | - The XAuth backend in eap-radius now supports multiple XAuth exchanges for |
1180 | different credential types and display messages. All user input gets | |
1181 | concatenated and verified with a single User-Password RADIUS attribute on | |
1182 | the AAA. With an AAA supporting it, one for example can implement | |
1183 | Password+Token authentication with proper dialogs on iOS and OS X clients. | |
1184 | ||
1185 | - charon supports IKEv1 Mode Config exchange in push mode. The ipsec.conf | |
1186 | modeconfig=push option enables it for both client and server, the same way | |
1187 | as pluto used it. | |
1188 | ||
390d2b50 MW |
1189 | - Using the "ah" ipsec.conf keyword on both IKEv1 and IKEv2 connections, |
1190 | charon can negotiate and install Security Associations integrity-protected by | |
1191 | the Authentication Header protocol. Supported are plain AH(+IPComp) SAs only, | |
1192 | but not the deprecated RFC2401 style ESP+AH bundles. | |
1193 | ||
1c1ba803 TB |
1194 | - The generation of initialization vectors for IKE and ESP (when using libipsec) |
1195 | is now modularized and IVs for e.g. AES-GCM are now correctly allocated | |
1196 | sequentially, while other algorithms like AES-CBC still use random IVs. | |
1197 | ||
38fb8e4e MW |
1198 | - The left and right options in ipsec.conf can take multiple address ranges |
1199 | and subnets. This allows connection matching against a larger set of | |
1200 | addresses, for example to use a different connection for clients connecting | |
1201 | from a internal network. | |
1202 | ||
34dff30c AS |
1203 | - For all those who have a queasy feeling about the NIST elliptic curve set, |
1204 | the Brainpool curves introduced for use with IKE by RFC 6932 might be a | |
1205 | more trustworthy alternative. | |
1206 | ||
390d2b50 MW |
1207 | - The kernel-libipsec userland IPsec backend now supports usage statistics, |
1208 | volume based rekeying and accepts ESPv3 style TFC padded packets. | |
1209 | ||
1c1ba803 TB |
1210 | - With two new strongswan.conf options fwmarks can be used to implement |
1211 | host-to-host tunnels with kernel-libipsec. | |
1212 | ||
38fb8e4e MW |
1213 | - load-tester supports transport mode connections and more complex traffic |
1214 | selectors, including such using unique ports for each tunnel. | |
2b32884d | 1215 | |
1c1ba803 TB |
1216 | - The new dnscert plugin provides support for authentication via CERT RRs that |
1217 | are protected via DNSSEC. The plugin was created by Ruslan N. Marchenko. | |
1218 | ||
1219 | - The eap-radius plugin supports forwarding of several Cisco Unity specific | |
1220 | RADIUS attributes in corresponding configuration payloads. | |
1221 | ||
1222 | - Database transactions are now abstracted and implemented by the two backends. | |
1223 | If you use MySQL make sure all tables use the InnoDB engine. | |
1224 | ||
390d2b50 MW |
1225 | - libstrongswan now can provide an experimental custom implementation of the |
1226 | printf family functions based on klibc if neither Vstr nor glibc style printf | |
1227 | hooks are available. This can avoid the Vstr dependency on some systems at | |
1228 | the cost of slower and less complete printf functions. | |
1229 | ||
fa2f6aa1 | 1230 | |
40b0a15c MW |
1231 | strongswan-5.1.0 |
1232 | ---------------- | |
1233 | ||
3a938a6f TB |
1234 | - Fixed a denial-of-service vulnerability triggered by specific XAuth usernames |
1235 | and EAP identities (since 5.0.3), and PEM files (since 4.1.11). The crash | |
1236 | was caused by insufficient error handling in the is_asn1() function. | |
1237 | The vulnerability has been registered as CVE-2013-5018. | |
1238 | ||
40b0a15c MW |
1239 | - The new charon-cmd command line IKE client can establish road warrior |
1240 | connections using IKEv1 or IKEv2 with different authentication profiles. | |
1241 | It does not depend on any configuration files and can be configured using a | |
1242 | few simple command line options. | |
1243 | ||
1244 | - The kernel-pfroute networking backend has been greatly improved. It now | |
78e6f69e | 1245 | can install virtual IPs on TUN devices on OS X and FreeBSD, allowing these |
40b0a15c MW |
1246 | systems to act as a client in common road warrior scenarios. |
1247 | ||
78e6f69e TB |
1248 | - The new kernel-libipsec plugin uses TUN devices and libipsec to provide IPsec |
1249 | processing in userland on Linux, FreeBSD and Mac OS X. | |
1250 | ||
68957d18 MW |
1251 | - The eap-radius plugin can now serve as an XAuth backend called xauth-radius, |
1252 | directly verifying XAuth credentials using RADIUS User-Name/User-Password | |
1253 | attributes. This is more efficient than the existing xauth-eap+eap-radius | |
1254 | combination, and allows RADIUS servers without EAP support to act as AAA | |
1255 | backend for IKEv1. | |
1256 | ||
78e6f69e | 1257 | - The new osx-attr plugin installs configuration attributes (currently DNS |
2334ae56 MW |
1258 | servers) via SystemConfiguration on Mac OS X. The keychain plugin provides |
1259 | certificates from the OS X keychain service. | |
78e6f69e TB |
1260 | |
1261 | - The sshkey plugin parses SSH public keys, which, together with the --agent | |
1262 | option for charon-cmd, allows the use of ssh-agent for authentication. | |
1263 | To configure SSH keys in ipsec.conf the left|rightrsasigkey options are | |
1264 | replaced with left|rightsigkey, which now take public keys in one of three | |
1265 | formats: SSH (RFC 4253, ssh: prefix), DNSKEY (RFC 3110, dns: prefix), and | |
1266 | PKCS#1 (the default, no prefix). | |
1267 | ||
1268 | - Extraction of certificates and private keys from PKCS#12 files is now provided | |
1269 | by the new pkcs12 plugin or the openssl plugin. charon-cmd (--p12) as well | |
1270 | as charon (via P12 token in ipsec.secrets) can make use of this. | |
1271 | ||
40b0a15c MW |
1272 | - IKEv2 can now negotiate transport mode and IPComp in NAT situations. |
1273 | ||
3a938a6f | 1274 | - IKEv2 exchange initiators now properly close an established IKE or CHILD_SA |
40b0a15c MW |
1275 | on error conditions using an additional exchange, keeping state in sync |
1276 | between peers. | |
1277 | ||
226f34e0 | 1278 | - Using a SQL database interface a Trusted Network Connect (TNC) Policy Manager |
78e6f69e TB |
1279 | can generate specific measurement workitems for an arbitrary number of |
1280 | Integrity Measurement Verifiers (IMVs) based on the history of the VPN user | |
1281 | and/or device. | |
1282 | ||
1283 | - Several core classes in libstrongswan are now tested with unit tests. These | |
1284 | can be enabled with --enable-unit-tests and run with 'make check'. Coverage | |
1285 | reports can be generated with --enable-coverage and 'make coverage' (this | |
1286 | disables any optimization, so it should not be enabled when building | |
1287 | production releases). | |
1288 | ||
56b753ca MW |
1289 | - The leak-detective developer tool has been greatly improved. It works much |
1290 | faster/stabler with multiple threads, does not use deprecated malloc hooks | |
1291 | anymore and has been ported to OS X. | |
1292 | ||
78e6f69e TB |
1293 | - chunk_hash() is now based on SipHash-2-4 with a random key. This provides |
1294 | better distribution and prevents hash flooding attacks when used with | |
1295 | hashtables. | |
1296 | ||
1297 | - All default plugins implement the get_features() method to define features | |
1298 | and their dependencies. The plugin loader has been improved, so that plugins | |
1299 | in a custom load statement can be ordered freely or to express preferences | |
1300 | without being affected by dependencies between plugin features. | |
1301 | ||
c3b8335c MW |
1302 | - A centralized thread can take care for watching multiple file descriptors |
1303 | concurrently. This removes the need for a dedicated listener threads in | |
1304 | various plugins. The number of "reserved" threads for such tasks has been | |
1305 | reduced to about five, depending on the plugin configuration. | |
1306 | ||
1307 | - Plugins that can be controlled by a UNIX socket IPC mechanism gained network | |
1308 | transparency. Third party applications querying these plugins now can use | |
1309 | TCP connections from a different host. | |
1310 | ||
78e6f69e | 1311 | - libipsec now supports AES-GCM. |
226f34e0 | 1312 | |
40b0a15c | 1313 | |
2e12fc4b AS |
1314 | strongswan-5.0.4 |
1315 | ---------------- | |
1316 | ||
1317 | - Fixed a security vulnerability in the openssl plugin which was reported by | |
1318 | Kevin Wojtysiak. The vulnerability has been registered as CVE-2013-2944. | |
1319 | Before the fix, if the openssl plugin's ECDSA signature verification was used, | |
1320 | due to a misinterpretation of the error code returned by the OpenSSL | |
1321 | ECDSA_verify() function, an empty or zeroed signature was accepted as a | |
1322 | legitimate one. | |
1323 | ||
1324 | - The handling of a couple of other non-security relevant openssl return codes | |
1325 | was fixed as well. | |
1326 | ||
1327 | - The tnc_ifmap plugin now publishes virtual IPv4 and IPv6 addresses via its | |
1328 | TCG TNC IF-MAP 2.1 interface. | |
1329 | ||
1330 | - The charon.initiator_only option causes charon to ignore IKE initiation | |
1331 | requests. | |
1332 | ||
bec5bf02 AS |
1333 | - The openssl plugin can now use the openssl-fips library. |
1334 | ||
2e12fc4b | 1335 | |
d69eb037 TB |
1336 | strongswan-5.0.3 |
1337 | ---------------- | |
1338 | ||
1339 | - The new ipseckey plugin enables authentication based on trustworthy public | |
1340 | keys stored as IPSECKEY resource records in the DNS and protected by DNSSEC. | |
1341 | To do so it uses a DNSSEC enabled resolver, like the one provided by the new | |
1342 | unbound plugin, which is based on libldns and libunbound. Both plugins were | |
1343 | created by Reto Guadagnini. | |
1344 | ||
1fc609fe AS |
1345 | - Implemented the TCG TNC IF-IMV 1.4 draft making access requestor identities |
1346 | available to an IMV. The OS IMV stores the AR identity together with the | |
1347 | device ID in the attest database. | |
1348 | ||
1349 | - The openssl plugin now uses the AES-NI accelerated version of AES-GCM | |
1350 | if the hardware supports it. | |
7a93844f | 1351 | |
96776d6f MW |
1352 | - The eap-radius plugin can now assign virtual IPs to IKE clients using the |
1353 | Framed-IP-Address attribute by using the "%radius" named pool in the | |
1354 | rightsourceip ipsec.conf option. Cisco Banner attributes are forwarded to | |
1355 | Unity-capable IKEv1 clients during mode config. charon now sends Interim | |
1356 | Accounting updates if requested by the RADIUS server, reports | |
1357 | sent/received packets in Accounting messages, and adds a Terminate-Cause | |
1358 | to Accounting-Stops. | |
1359 | ||
1360 | - The recently introduced "ipsec listcounters" command can report connection | |
1361 | specific counters by passing a connection name, and global or connection | |
1362 | counters can be reset by the "ipsec resetcounters" command. | |
1363 | ||
1364 | - The strongSwan libpttls library provides an experimental implementation of | |
1365 | PT-TLS (RFC 6876), a Posture Transport Protocol over TLS. | |
1366 | ||
1367 | - The charon systime-fix plugin can disable certificate lifetime checks on | |
1368 | embedded systems if the system time is obviously out of sync after bootup. | |
1369 | Certificates lifetimes get checked once the system time gets sane, closing | |
1370 | or reauthenticating connections using expired certificates. | |
1371 | ||
1372 | - The "ikedscp" ipsec.conf option can set DiffServ code points on outgoing | |
1373 | IKE packets. | |
7a93844f | 1374 | |
e34666a4 TB |
1375 | - The new xauth-noauth plugin allows to use basic RSA or PSK authentication with |
1376 | clients that cannot be configured without XAuth authentication. The plugin | |
1377 | simply concludes the XAuth exchange successfully without actually performing | |
1378 | any authentication. Therefore, to use this backend it has to be selected | |
1379 | explicitly with rightauth2=xauth-noauth. | |
1380 | ||
db50a35a RB |
1381 | - The new charon-tkm IKEv2 daemon delegates security critical operations to a |
1382 | separate process. This has the benefit that the network facing daemon has no | |
1383 | knowledge of keying material used to protect child SAs. Thus subverting | |
1384 | charon-tkm does not result in the compromise of cryptographic keys. | |
1385 | The extracted functionality has been implemented from scratch in a minimal TCB | |
1386 | (trusted computing base) in the Ada programming language. Further information | |
e4a3ef2e | 1387 | can be found at https://www.codelabs.ch/tkm/. |
db50a35a | 1388 | |
c2a5e7bc AS |
1389 | strongswan-5.0.2 |
1390 | ---------------- | |
1391 | ||
1392 | - Implemented all IETF Standard PA-TNC attributes and an OS IMC/IMV | |
1393 | pair using them to transfer operating system information. | |
1394 | ||
a19d5913 MW |
1395 | - The new "ipsec listcounters" command prints a list of global counter values |
1396 | about received and sent IKE messages and rekeyings. | |
1397 | ||
343e9989 MW |
1398 | - A new lookip plugin can perform fast lookup of tunnel information using a |
1399 | clients virtual IP and can send notifications about established or deleted | |
1400 | tunnels. The "ipsec lookip" command can be used to query such information | |
1401 | or receive notifications. | |
1402 | ||
ecdd5aed MW |
1403 | - The new error-notify plugin catches some common error conditions and allows |
1404 | an external application to receive notifications for them over a UNIX socket. | |
1405 | ||
6910e5c7 MW |
1406 | - IKE proposals can now use a PRF algorithm different to that defined for |
1407 | integrity protection. If an algorithm with a "prf" prefix is defined | |
1408 | explicitly (such as prfsha1 or prfsha256), no implicit PRF algorithm based on | |
1409 | the integrity algorithm is added to the proposal. | |
c2a5e7bc | 1410 | |
8fc7bbc6 MW |
1411 | - The pkcs11 plugin can now load leftcert certificates from a smartcard for a |
1412 | specific ipsec.conf conn section and cacert CA certificates for a specific ca | |
1413 | section. | |
1414 | ||
78b2a2b1 MW |
1415 | - The load-tester plugin gained additional options for certificate generation |
1416 | and can load keys and multiple CA certificates from external files. It can | |
1417 | install a dedicated outer IP address for each tunnel and tunnel initiation | |
1418 | batches can be triggered and monitored externally using the | |
1419 | "ipsec load-tester" tool. | |
1420 | ||
cc0cc3b5 MW |
1421 | - PKCS#7 container parsing has been modularized, and the openssl plugin |
1422 | gained an alternative implementation to decrypt and verify such files. | |
1423 | In contrast to our own DER parser, OpenSSL can handle BER files, which is | |
1424 | required for interoperability of our scepclient with EJBCA. | |
1425 | ||
f31b4180 TB |
1426 | - Support for the proprietary IKEv1 fragmentation extension has been added. |
1427 | Fragments are always handled on receipt but only sent if supported by the peer | |
1428 | and if enabled with the new fragmentation ipsec.conf option. | |
1429 | ||
0e0870ae MW |
1430 | - IKEv1 in charon can now parse certificates received in PKCS#7 containers and |
1431 | supports NAT traversal as used by Windows clients. Patches courtesy of | |
1432 | Volker Rümelin. | |
1433 | ||
2f0441a3 MW |
1434 | - The new rdrand plugin provides a high quality / high performance random |
1435 | source using the Intel rdrand instruction found on Ivy Bridge processors. | |
1436 | ||
73791223 TB |
1437 | - The integration test environment was updated and now uses KVM and reproducible |
1438 | guest images based on Debian. | |
1439 | ||
1fc609fe | 1440 | |
ecfd714c AS |
1441 | strongswan-5.0.1 |
1442 | ---------------- | |
1443 | ||
6f93927b AS |
1444 | - Introduced the sending of the standard IETF Assessment Result |
1445 | PA-TNC attribute by all strongSwan Integrity Measurement Verifiers. | |
1446 | ||
ecfd714c AS |
1447 | - Extended PTS Attestation IMC/IMV pair to provide full evidence of |
1448 | the Linux IMA measurement process. All pertinent file information | |
6f93927b | 1449 | of a Linux OS can be collected and stored in an SQL database. |
ecfd714c AS |
1450 | |
1451 | - The PA-TNC and PB-TNC protocols can now process huge data payloads | |
1452 | >64 kB by distributing PA-TNC attributes over multiple PA-TNC messages | |
1453 | and these messages over several PB-TNC batches. As long as no | |
b3ab7a48 | 1454 | consolidated recommendation from all IMVs can be obtained, the TNC |
ecfd714c AS |
1455 | server requests more client data by sending an empty SDATA batch. |
1456 | ||
804d702b MW |
1457 | - The rightgroups2 ipsec.conf option can require group membership during |
1458 | a second authentication round, for example during XAuth authentication | |
1459 | against a RADIUS server. | |
1460 | ||
3423b3a8 MW |
1461 | - The xauth-pam backend can authenticate IKEv1 XAuth and Hybrid authenticated |
1462 | clients against any PAM service. The IKEv2 eap-gtc plugin does not use | |
1463 | PAM directly anymore, but can use any XAuth backend to verify credentials, | |
1464 | including xauth-pam. | |
1465 | ||
cc48f360 MW |
1466 | - The new unity plugin brings support for some parts of the IKEv1 Cisco Unity |
1467 | Extension. As client, charon narrows traffic selectors to the received | |
1468 | Split-Include attributes and automatically installs IPsec bypass policies | |
1469 | for received Local-LAN attributes. As server, charon sends Split-Include | |
1470 | attributes for leftsubnet definitions containing multiple subnets to Unity- | |
1471 | aware clients. | |
1472 | ||
cbe244a5 TB |
1473 | - An EAP-Nak payload is returned by clients if the gateway requests an EAP |
1474 | method that the client does not support. Clients can also request a specific | |
1475 | EAP method by configuring that method with leftauth. | |
1476 | ||
1477 | - The eap-dynamic plugin handles EAP-Nak payloads returned by clients and uses | |
1478 | these to select a different EAP method supported/requested by the client. | |
1479 | The plugin initially requests the first registered method or the first method | |
1480 | configured with charon.plugins.eap-dynamic.preferred. | |
1481 | ||
e76f3d0d MW |
1482 | - The new left/rightdns options specify connection specific DNS servers to |
1483 | request/respond in IKEv2 configuration payloads or IKEv2 mode config. leftdns | |
1484 | can be any (comma separated) combination of %config4 and %config6 to request | |
1485 | multiple servers, both for IPv4 and IPv6. rightdns takes a list of DNS server | |
1486 | IP addresses to return. | |
1487 | ||
69e056a2 MW |
1488 | - The left/rightsourceip options now accept multiple addresses or pools. |
1489 | leftsourceip can be any (comma separated) combination of %config4, %config6 | |
1490 | or fixed IP addresses to request. rightsourceip accepts multiple explicitly | |
1491 | specified or referenced named pools. | |
1492 | ||
1493 | - Multiple connections can now share a single address pool when they use the | |
1494 | same definition in one of the rightsourceip pools. | |
1495 | ||
4a025539 TB |
1496 | - The options charon.interfaces_ignore and charon.interfaces_use allow one to |
1497 | configure the network interfaces used by the daemon. | |
1498 | ||
1499 | - The kernel-netlink plugin supports the charon.install_virtual_ip_on option, | |
1500 | which specifies the interface on which virtual IP addresses will be installed. | |
1501 | If it is not specified the current behavior of using the outbound interface | |
1502 | is preserved. | |
1503 | ||
1504 | - The kernel-netlink plugin tries to keep the current source address when | |
1505 | looking for valid routes to reach other hosts. | |
1506 | ||
804d702b MW |
1507 | - The autotools build has been migrated to use a config.h header. strongSwan |
1508 | development headers will get installed during "make install" if | |
1509 | --with-dev-headers has been passed to ./configure. | |
1510 | ||
1511 | - All crypto primitives gained return values for most operations, allowing | |
1512 | crypto backends to fail, for example when using hardware accelerators. | |

1515 | strongswan-5.0.0 |
1516 | ---------------- | |
1517 | ||
794cdbc5 MW |
1518 | - The charon IKE daemon gained experimental support for the IKEv1 protocol. |
1519 | Pluto has been removed from the 5.x series, and unless strongSwan is | |
1520 | configured with --disable-ikev1 or --disable-ikev2, charon handles both | |
1521 | keying protocols. The feature-set of IKEv1 in charon is almost on par with | |
1522 | pluto, but currently does not support AH or bundled AH+ESP SAs. Beside | |
1523 | RSA/ECDSA, PSK and XAuth, charon also supports the Hybrid authentication | |
ca280574 | 1524 | mode. Information for interoperability and migration is available at |
e4a3ef2e | 1525 | https://wiki.strongswan.org/projects/strongswan/wiki/CharonPlutoIKEv1. |
794cdbc5 | 1526 | |
d55c2404 TB |
1527 | - Charon's bus_t has been refactored so that loggers and other listeners are |
1528 | now handled separately. The single lock was previously cause for deadlocks | |
1529 | if extensive listeners, such as the one provided by the updown plugin, wanted | |
1530 | to acquire locks that were held by other threads which in turn tried to log | |
1531 | messages, and thus were waiting to acquire the same lock currently held by | |
1532 | the thread calling the listener. | |
1533 | The implemented changes also allow the use of a read/write-lock for the | |
1534 | loggers which increases performance if multiple loggers are registered. | |
1535 | Besides several interface changes this last bit also changes the semantics | |
1536 | for loggers as these may now be called by multiple threads at the same time. | |
1537 | ||
ed7186cb TB |
1538 | - Source routes are reinstalled if interfaces are reactivated or IP addresses |
1539 | reappear. | |
1540 | ||
f97c269e TB |
1541 | - The thread pool (processor_t) now has more control over the lifecycle of |
1542 | a job (see job.h for details). In particular, it now controls the destruction | |
1543 | of jobs after execution and the cancellation of jobs during shutdown. Due to | |
1544 | these changes the requeueing feature, previously available to callback_job_t | |
1545 | only, is now available to all jobs (in addition to a new rescheduling | |
1546 | feature). | |
1547 | ||
5a6e5e0d MW |
1548 | - In addition to trustchain key strength definitions for different public key |
1549 | systems, the rightauth option now takes a list of signature hash algorithms | |
1550 | considered save for trustchain validation. For example, the setting | |
1551 | rightauth=rsa-2048-ecdsa-256-sha256-sha384-sha512 requires a trustchain | |
1552 | that uses at least RSA-2048 or ECDSA-256 keys and certificate signatures | |
1553 | using SHA-256 or better. | |
1554 | ||

93d9a02e TB |
1556 | strongswan-4.6.4 |
1557 | ---------------- | |
1558 | ||
1559 | - Fixed a security vulnerability in the gmp plugin. If this plugin was used | |
1560 | for RSA signature verification an empty or zeroed signature was handled as | |
1561 | a legitimate one. | |
1562 | ||
1563 | - Fixed several issues with reauthentication and address updates. | |
1564 | ||
1565 | ||
c224f765 AS |
1566 | strongswan-4.6.3 |
1567 | ---------------- | |
1568 | ||
1569 | - The tnc-pdp plugin implements a RADIUS server interface allowing | |
1570 | a strongSwan TNC server to act as a Policy Decision Point. | |
1571 | ||
4bc7577d MW |
1572 | - The eap-radius authentication backend enforces Session-Timeout attributes |
1573 | using RFC4478 repeated authentication and acts upon RADIUS Dynamic | |
1574 | Authorization extensions, RFC 5176. Currently supported are disconnect | |
1575 | requests and CoA messages containing a Session-Timeout. | |
1576 | ||
1577 | - The eap-radius plugin can forward arbitrary RADIUS attributes from and to | |
1578 | clients using custom IKEv2 notify payloads. The new radattr plugin reads | |
1579 | attributes to include from files and prints received attributes to the | |
1580 | console. | |
c224f765 AS |
1581 | |
1582 | - Added support for untruncated MD5 and SHA1 HMACs in ESP as used in | |
1583 | RFC 4595. | |
1584 | ||
d7590217 TB |
1585 | - The cmac plugin implements the AES-CMAC-96 and AES-CMAC-PRF-128 algorithms |
1586 | as defined in RFC 4494 and RFC 4615, respectively. | |
1587 | ||
4e2e77d5 | 1588 | - The resolve plugin automatically installs nameservers via resolvconf(8), |
a281494a | 1589 | if it is installed, instead of modifying /etc/resolv.conf directly. |
c224f765 | 1590 | |
5f1931ad AS |
1591 | - The IKEv2 charon daemon supports now raw RSA public keys in RFC 3110 |
1592 | DNSKEY and PKCS#1 file format. | |
1593 | ||
1594 | ||
60e99b37 AS |
1595 | strongswan-4.6.2 |
1596 | ---------------- | |
1597 | ||
1598 | - Upgraded the TCG IF-IMC and IF-IMV C API to the upcoming version 1.3 | |
1599 | which supports IF-TNCCS 2.0 long message types, the exclusive flags | |
1600 | and multiple IMC/IMV IDs. Both the TNC Client and Server as well as | |
1601 | the "Test", "Scanner", and "Attestation" IMC/IMV pairs were updated. | |
1602 | ||
1603 | - Fully implemented the "TCG Attestation PTS Protocol: Binding to IF-M" | |
1604 | standard (TLV-based messages only). TPM-based remote attestation of | |
de4a0c83 AS |
1605 | Linux IMA (Integrity Measurement Architecture) possible. Measurement |
1606 | reference values are automatically stored in an SQLite database. | |
60e99b37 | 1607 | |
a345aa26 MW |
1608 | - The EAP-RADIUS authentication backend supports RADIUS accounting. It sends |
1609 | start/stop messages containing Username, Framed-IP and Input/Output-Octets | |
1610 | attributes and has been tested against FreeRADIUS and Microsoft NPS. | |
60e99b37 | 1611 | |
de4a0c83 AS |
1612 | - Added support for PKCS#8 encoded private keys via the libstrongswan |
1613 | pkcs8 plugin. This is the default format used by some OpenSSL tools since | |
1614 | version 1.0.0 (e.g. openssl req with -keyout). | |
dcefa267 | 1615 | |
a8958012 MW |
1616 | - Added session resumption support to the strongSwan TLS stack. |
1617 | ||
de4a0c83 | 1618 | |
acb92cb4 AS |
1619 | strongswan-4.6.1 |
1620 | ---------------- | |
1621 | ||
1622 | - Because of changing checksums before and after installation which caused | |
1623 | the integrity tests to fail we avoided directly linking libsimaka, libtls and | |
1624 | libtnccs to those libcharon plugins which make use of these dynamic libraries. | |
18f85b66 AS |
1625 | Instead we linked the libraries to the charon daemon. Unfortunately Ubuntu |
1626 | 11.10 activated the --as-needed ld option which discards explicit links | |
1627 | to dynamic libraries that are not actually used by the charon daemon itself, | |
1628 | thus causing failures during the loading of the plugins which depend on these | |
1629 | libraries for resolving external symbols. | |
acb92cb4 | 1630 | |
53f8ac3d TB |
1631 | - Therefore our approach of computing integrity checksums for plugins had to be |
1632 | changed radically by moving the hash generation from the compilation to the | |
1633 | post-installation phase. | |
5ed3e3a7 | 1634 | |

5a2e2e0b AS |
1637 | ---------------- |
1638 | ||
37276728 MW |
1639 | - The new libstrongswan certexpire plugin collects expiration information of |
1640 | all used certificates and exports them to CSV files. It either directly | |
1641 | exports them or uses cron style scheduling for batch exports. | |
1642 | ||
1643 | - starter passes unresolved hostnames to charon, allowing it to do name | |
1644 | resolution not before the connection attempt. This is especially useful with | |
1645 | connections between hosts using dynamic IP addresses. Thanks to Mirko Parthey | |
1646 | for the initial patch. | |
1647 | ||
5fd8e530 TB |
1648 | - The android plugin can now be used without the Android frontend patch and |
1649 | provides DNS server registration and logging to logcat. | |
1650 | ||
1651 | - Pluto and starter (plus stroke and whack) have been ported to Android. | |
1652 | ||
602ee58e TB |
1653 | - Support for ECDSA private and public key operations has been added to the |
1654 | pkcs11 plugin. The plugin now also provides DH and ECDH via PKCS#11 and can | |
1655 | use tokens as random number generators (RNG). By default only private key | |
1656 | operations are enabled, more advanced features have to be enabled by their | |
1657 | option in strongswan.conf. This also applies to public key operations (even | |
1658 | for keys not stored on the token) which were enabled by default before. | |
1659 | ||
37276728 MW |
1660 | - The libstrongswan plugin system now supports detailed plugin dependencies. |
1661 | Many plugins have been extended to export its capabilities and requirements. | |
1662 | This allows the plugin loader to resolve plugin loading order automatically, | |
1663 | and in future releases, to dynamically load the required features on demand. | |
1664 | Existing third party plugins are source (but not binary) compatible if they | |
1665 | properly initialize the new get_features() plugin function to NULL. | |
1666 | ||
fd81ac05 AS |
1667 | - The tnc-ifmap plugin implements a TNC IF-MAP 2.0 client which can deliver |
1668 | metadata about IKE_SAs via a SOAP interface to a MAP server. The tnc-ifmap | |
1669 | plugin requires the Apache Axis2/C library. | |
1670 | ||
37276728 | 1671 | |
5d179d19 AS |
1672 | strongswan-4.5.3 |
1673 | ---------------- | |
1674 | ||
a7edbd21 | 1675 | - Our private libraries (e.g. libstrongswan) are not installed directly in |
b18a697a AS |
1676 | prefix/lib anymore. Instead a subdirectory is used (prefix/lib/ipsec/ by |
1677 | default). The plugins directory is also moved from libexec/ipsec/ to that | |
a7edbd21 TB |
1678 | directory. |
1679 | ||
b18a697a AS |
1680 | - The dynamic IMC/IMV libraries were moved from the plugins directory to |
1681 | a new imcvs directory in the prefix/lib/ipsec/ subdirectory. | |
1682 | ||
107ea60f TB |
1683 | - Job priorities were introduced to prevent thread starvation caused by too |
1684 | many threads handling blocking operations (such as CRL fetching). Refer to | |
1685 | strongswan.conf(5) for details. | |
1686 | ||
1687 | - Two new strongswan.conf options allow to fine-tune performance on IKEv2 | |
1688 | gateways by dropping IKE_SA_INIT requests on high load. | |
1689 | ||
f8799170 | 1690 | - IKEv2 charon daemon supports start PASS and DROP shunt policies |
b18a697a | 1691 | preventing traffic to go through IPsec connections. Installation of the |
107ea60f TB |
1692 | shunt policies either via the XFRM netfilter or PFKEYv2 IPsec kernel |
1693 | interfaces. | |
f8799170 | 1694 | |
93095183 TB |
1695 | - The history of policies installed in the kernel is now tracked so that e.g. |
1696 | trap policies are correctly updated when reauthenticated SAs are terminated. | |
1697 | ||
b18a697a AS |
1698 | - IMC/IMV Scanner pair implementing the RFC 5792 PA-TNC (IF-M) protocol. |
1699 | Using "netstat -l" the IMC scans open listening ports on the TNC client | |
1700 | and sends a port list to the IMV which based on a port policy decides if | |
1701 | the client is admitted to the network. | |
1702 | (--enable-imc-scanner/--enable-imv-scanner). | |
1703 | ||
1704 | - IMC/IMV Test pair implementing the RFC 5792 PA-TNC (IF-M) protocol. | |
5d179d19 AS |
1705 | (--enable-imc-test/--enable-imv-test). |
1706 | ||
4876f896 MW |
1707 | - The IKEv2 close action does not use the same value as the ipsec.conf dpdaction |
1708 | setting, but the value defined by its own closeaction keyword. The action | |
1709 | is triggered if the remote peer closes a CHILD_SA unexpectedly. | |
5d179d19 | 1710 | |
5a2e2e0b | 1711 | |
6f2378c1 AS |
1712 | strongswan-4.5.2 |
1713 | ---------------- | |
1714 | ||
320e98c2 MW |
1715 | - The whitelist plugin for the IKEv2 daemon maintains an in-memory identity |
1716 | whitelist. Any connection attempt of peers not whitelisted will get rejected. | |
1717 | The 'ipsec whitelist' utility provides a simple command line frontend for | |
1718 | whitelist administration. | |
1719 | ||
92ebb7c5 | 1720 | - The duplicheck plugin provides a specialized form of duplicate checking, |
5832d505 | 1721 | doing a liveness check on the old SA and optionally notify a third party |
92ebb7c5 MW |
1722 | application about detected duplicates. |
1723 | ||
1724 | - The coupling plugin permanently couples two or more devices by limiting | |
1725 | authentication to previously used certificates. | |
1726 | ||
6f2378c1 AS |
1727 | - In the case that the peer config and child config don't have the same name |
1728 | (usually in SQL database defined connections), ipsec up|route <peer config> | |
1729 | starts|routes all associated child configs and ipsec up|route <child config> | |
1730 | only starts|routes the specific child config. | |
1731 | ||
6ca05fe2 AS |
1732 | - fixed the encoding and parsing of X.509 certificate policy statements (CPS). |
1733 | ||
1ee7440b AS |
1734 | - Duncan Salerno contributed the eap-sim-pcsc plugin implementing a |
1735 | pcsc-lite based SIM card backend. | |
1736 | ||
1737 | - The eap-peap plugin implements the EAP PEAP protocol. Interoperates | |
2778b664 | 1738 | successfully with a FreeRADIUS server and Windows 7 Agile VPN clients. |
1ee7440b | 1739 | |
cf6ca6d7 MW |
1740 | - The IKEv2 daemon charon rereads strongswan.conf on SIGHUP and instructs |
1741 | all plugins to reload. Currently only the eap-radius and the attr plugins | |
1742 | support configuration reloading. | |
1743 | ||
d3d21c29 MW |
1744 | - Added userland support to the IKEv2 daemon for Extended Sequence Numbers |
1745 | support coming with Linux 2.6.39. To enable ESN on a connection, add | |
1746 | the 'esn' keyword to the proposal. The default proposal uses 32-bit sequence | |
1747 | numbers only ('noesn'), and the same value is used if no ESN mode is | |
1748 | specified. To negotiate ESN support with the peer, include both, e.g. | |
1749 | esp=aes128-sha1-esn-noesn. | |
1750 | ||
1751 | - In addition to ESN, Linux 2.6.39 gained support for replay windows larger | |
1752 | than 32 packets. The new global strongswan.conf option 'charon.replay_window' | |
1753 | configures the size of the replay window, in packets. | |
1754 | ||
6f2378c1 | 1755 | |
41ba5ce7 AS |
1756 | strongswan-4.5.1 |
1757 | ---------------- | |
1758 | ||
1b7e081b AS |
1759 | - Sansar Choinyambuu implemented the RFC 5793 Posture Broker Protocol (BP) |
1760 | compatible with Trusted Network Connect (TNC). The TNCCS 2.0 protocol | |
5cdaafef | 1761 | requires the tnccs_20, tnc_imc and tnc_imv plugins but does not depend |
1b7e081b AS |
1762 | on the libtnc library. Any available IMV/IMC pairs conforming to the |
1763 | Trusted Computing Group's TNC-IF-IMV/IMC 1.2 interface specification | |
e44817df | 1764 | can be loaded via /etc/tnc_config. |
1b7e081b | 1765 | |
5cdaafef AS |
1766 | - Re-implemented the TNCCS 1.1 protocol by using the tnc_imc and tnc_imv |
1767 | in place of the external libtnc library. | |
1768 | ||
1769 | - The tnccs_dynamic plugin loaded on a TNC server in addition to the | |
1770 | tnccs_11 and tnccs_20 plugins, dynamically detects the IF-TNCCS | |
1771 | protocol version used by a TNC client and invokes an instance of | |
1772 | the corresponding protocol stack. | |
1773 | ||
41ba5ce7 AS |
1774 | - IKE and ESP proposals can now be stored in an SQL database using a |
1775 | new proposals table. The start_action field in the child_configs | |
1776 | tables allows the automatic starting or routing of connections stored | |
1777 | in an SQL database. | |
1778 | ||
1b7e081b AS |
1779 | - The new certificate_authorities and certificate_distribution_points |
1780 | tables make it possible to store CRL and OCSP Certificate Distribution | |
1781 | points in an SQL database. | |
1782 | ||
ae09bc62 TB |
1783 | - The new 'include' statement allows to recursively include other files in |
1784 | strongswan.conf. Existing sections and values are thereby extended and | |
1785 | replaced, respectively. | |
1786 | ||
1787 | - Due to the changes in the parser for strongswan.conf, the configuration | |
1788 | syntax for the attr plugin has changed. Previously, it was possible to | |
1789 | specify multiple values of a specific attribute type by adding multiple | |
1790 | key/value pairs with the same key (e.g. dns) to the plugins.attr section. | |
1791 | Because values with the same key now replace previously defined values | |
1792 | this is not possible anymore. As an alternative, multiple values can be | |
1793 | specified by separating them with a comma (e.g. dns = 1.2.3.4, 2.3.4.5). | |
1794 | ||
840e7044 AS |
1795 | - ipsec listalgs now appends (set in square brackets) to each crypto |
1796 | algorithm listed the plugin that registered the function. | |
1797 | ||
e44817df MW |
1798 | - Traffic Flow Confidentiality padding supported with Linux 2.6.38 can be used |
1799 | by the IKEv2 daemon. The ipsec.conf 'tfc' keyword pads all packets to a given | |
1800 | boundary, the special value '%mtu' pads all packets to the path MTU. | |
1801 | ||
78a547c9 MW |
1802 | - The new af-alg plugin can use various crypto primitives of the Linux Crypto |
1803 | API using the AF_ALG interface introduced with 2.6.38. This removes the need | |
1804 | for additional userland implementations of symmetric cipher, hash, hmac and | |
1805 | xcbc algorithms. | |
44582075 | 1806 | |
41ed0294 | 1807 | - The IKEv2 daemon supports the INITIAL_CONTACT notify as initiator and |
983a5e88 MW |
1808 | responder. The notify is sent when initiating configurations with a unique |
1809 | policy, set in ipsec.conf via the global 'uniqueids' option. | |
41ed0294 | 1810 | |
f0783464 MW |
1811 | - The conftest conformance testing framework enables the IKEv2 stack to perform |
1812 | many tests using a distinct tool and configuration frontend. Various hooks | |
1813 | can alter reserved bits, flags, add custom notifies and proposals, reorder | |
1814 | or drop messages and much more. It is enabled using the --enable-conftest | |
1815 | ./configure switch. | |
1816 | ||
77eee25f | 1817 | - The new libstrongswan constraints plugin provides advanced X.509 constraint |
cf95d292 | 1818 | checking. In addition to X.509 pathLen constraints, the plugin checks for |
77eee25f MW |
1819 | nameConstraints and certificatePolicies, including policyMappings and |
1820 | policyConstraints. The x509 certificate plugin and the pki tool have been | |
96c4addc MW |
1821 | enhanced to support these extensions. The new left/rightcertpolicy ipsec.conf |
1822 | connection keywords take OIDs a peer certificate must have. | |
1823 | ||
1824 | - The left/rightauth ipsec.conf keywords accept values with a minimum strength | |
1825 | for trustchain public keys in bits, such as rsa-2048 or ecdsa-256. | |
77eee25f | 1826 | |
fb1e7df1 MW |
1827 | - The revocation and x509 libstrongswan plugins and the pki tool gained basic |
1828 | support for delta CRLs. | |
1829 | ||
5cdaafef | 1830 | |
44582075 MW |
1831 | strongswan-4.5.0 |
1832 | ---------------- | |
1833 | ||
b14923ec AS |
1834 | - IMPORTANT: the default keyexchange mode 'ike' is changing with release 4.5 |
1835 | from 'ikev1' to 'ikev2', thus commemorating the five year anniversary of the | |
ac544be2 | 1836 | IKEv2 RFC 4306 and its mature successor RFC 5996. The time has definitively |
b14923ec | 1837 | come for IKEv1 to go into retirement and to cede its place to the much more |
ac544be2 | 1838 | robust, powerful and versatile IKEv2 protocol! |
b14923ec | 1839 | |
44582075 MW |
1840 | - Added new ctr, ccm and gcm plugins providing Counter, Counter with CBC-MAC |
1841 | and Galois/Counter Modes based on existing CBC implementations. These | |
1842 | new plugins bring support for AES and Camellia Counter and CCM algorithms | |
1843 | and the AES GCM algorithms for use in IKEv2. | |
1844 | ||
84c9bc42 MW |
1845 | - The new pkcs11 plugin brings full Smartcard support to the IKEv2 daemon and |
1846 | the pki utility using one or more PKCS#11 libraries. It currently supports | |
61df42cc | 1847 | RSA private and public key operations and loads X.509 certificates from |
84c9bc42 MW |
1848 | tokens. |
1849 | ||
a782b52f MW |
1850 | - Implemented a general purpose TLS stack based on crypto and credential |
1851 | primitives of libstrongswan. libtls supports TLS versions 1.0, 1.1 and 1.2, | |
1852 | ECDHE-ECDSA/RSA, DHE-RSA and RSA key exchange algorithms and RSA/ECDSA based | |
1853 | client authentication. | |
1854 | ||
1855 | - Based on libtls, the eap-tls plugin brings certificate based EAP | |
1856 | authentication for client and server. It is compatible to Windows 7 IKEv2 | |
61df42cc | 1857 | Smartcard authentication and the OpenSSL based FreeRADIUS EAP-TLS backend. |
a782b52f | 1858 | |
8a1353fc AS |
1859 | - Implemented the TNCCS 1.1 Trusted Network Connect protocol using the |
1860 | libtnc library on the strongSwan client and server side via the tnccs_11 | |
1861 | plugin and optionally connecting to a TNC@FHH-enhanced FreeRADIUS AAA server. | |
1862 | Depending on the resulting TNC Recommendation, strongSwan clients are granted | |
1863 | access to a network behind a strongSwan gateway (allow), are put into a | |
ac544be2 | 1864 | remediation zone (isolate) or are blocked (none), respectively. Any number |
8a1353fc AS |
1865 | of Integrity Measurement Collector/Verifier pairs can be attached |
1866 | via the tnc-imc and tnc-imv charon plugins. | |
1867 | ||
b3cabd1f TB |
1868 | - The IKEv1 daemon pluto now uses the same kernel interfaces as the IKEv2 |
1869 | daemon charon. As a result of this, pluto now supports xfrm marks which | |
1870 | were introduced in charon with 4.4.1. | |
1871 | ||
1872 | - Applets for Maemo 5 (Nokia) allow to easily configure and control IKEv2 | |
1873 | based VPN connections with EAP authentication on supported devices. | |
1874 | ||
18a4f865 MW |
1875 | - The RADIUS plugin eap-radius now supports multiple RADIUS servers for |
1876 | redundant setups. Servers are selected by a defined priority, server load and | |
1877 | availability. | |
1878 | ||
1879 | - The simple led plugin controls hardware LEDs through the Linux LED subsystem. | |
1880 | It currently shows activity of the IKE daemon and is a good example how to | |
1881 | implement a simple event listener. | |
1882 | ||
b3cabd1f TB |
1883 | - Improved MOBIKE behavior in several corner cases, for instance, if the |
1884 | initial responder moves to a different address. | |
1885 | ||
1886 | - Fixed left-/rightnexthop option, which was broken since 4.4.0. | |
1887 | ||
3f84e2d6 AS |
1888 | - Fixed a bug not releasing a virtual IP address to a pool if the XAUTH |
1889 | identity was different from the IKE identity. | |
1890 | ||
f6032361 AS |
1891 | - Fixed the alignment of ModeConfig messages on 4-byte boundaries in the |
1892 | case where the attributes are not a multiple of 4 bytes (e.g. Cisco's | |
1893 | UNITY_BANNER). | |
1894 | ||
1895 | - Fixed the interoperability of the socket_raw and socket_default | |
1896 | charon plugins. | |
1897 | ||
3f84e2d6 AS |
1898 | - Added man page for strongswan.conf |

1901 | strongswan-4.4.1 |
1902 | ---------------- | |
1903 | ||
ec40c02a | 1904 | - Support of xfrm marks in IPsec SAs and IPsec policies introduced |
b22bb9f2 AS |
1905 | with the Linux 2.6.34 kernel. For details see the example scenarios |
1906 | ikev2/nat-two-rw-mark, ikev2/rw-nat-mark-in-out and ikev2/net2net-psk-dscp. | |
ec40c02a | 1907 | |
b22bb9f2 | 1908 | - The PLUTO_MARK_IN and PLUTO_ESP_ENC environment variables can be used |
b59340a2 AS |
1909 | in a user-specific updown script to set marks on inbound ESP or |
1910 | ESP_IN_UDP packets. | |
e87b78c6 | 1911 | |
3561cc4b AS |
1912 | - The openssl plugin now supports X.509 certificate and CRL functions. |
1913 | ||
e9448cfc | 1914 | - OCSP/CRL checking in IKEv2 has been moved to the revocation plugin, enabled |
2db6d5b8 | 1915 | by default. Please update manual load directives in strongswan.conf. |
e9448cfc MW |
1916 | |
1917 | - RFC3779 ipAddrBlock constraint checking has been moved to the addrblock | |
1918 | plugin, disabled by default. Enable it and update manual load directives | |
1919 | in strongswan.conf, if required. | |
1920 | ||
7f3a9468 MW |
1921 | - The pki utility supports CRL generation using the --signcrl command. |
1922 | ||
1923 | - The ipsec pki --self, --issue and --req commands now support output in | |
1924 | PEM format using the --outform pem option. | |
1925 | ||
03b5e4d8 AS |
1926 | - The major refactoring of the IKEv1 Mode Config functionality now allows |
1927 | the transport and handling of any Mode Config attribute. | |
1928 | ||
e87b78c6 | 1929 | - The RADIUS proxy plugin eap-radius now supports multiple servers. Configured |
b59340a2 AS |
1930 | servers are chosen randomly, with the option to prefer a specific server. |
1931 | Non-responding servers are degraded by the selection process. | |
e87b78c6 | 1932 | |
c5c6f9b6 AS |
1933 | - The ipsec pool tool manages arbitrary configuration attributes stored |
1934 | in an SQL database. ipsec pool --help gives the details. | |
1935 | ||
fe2434cf MW |
1936 | - The new eap-simaka-sql plugin acts as a backend for EAP-SIM and EAP-AKA, |
1937 | reading triplets/quintuplets from an SQL database. | |
1938 | ||
c8bd06c7 MW |
1939 | - The High Availability plugin now supports a HA enabled in-memory address |
1940 | pool and Node reintegration without IKE_SA rekeying. The latter allows | |
1941 | clients without IKE_SA rekeying support to keep connected during | |
1942 | reintegration. Additionally, many other issues have been fixed in the ha | |
1943 | plugin. | |
1c1f132a | 1944 | |
c5c921bf MW |
1945 | - Fixed a potential remote code execution vulnerability resulting from |
1946 | the misuse of snprintf(). The vulnerability is exploitable by | |
1947 | unauthenticated users. | |
1948 | ||
03b5e4d8 | 1949 | |
00c60592 MW |
1950 | strongswan-4.4.0 |
1951 | ---------------- | |
1952 | ||
d101a61f MW |
1953 | - The IKEv2 High Availability plugin has been integrated. It provides |
1954 | load sharing and failover capabilities in a cluster of currently two nodes, | |
1955 | based on an extend ClusterIP kernel module. More information is available at | |
e4a3ef2e | 1956 | https://wiki.strongswan.org/projects/strongswan/wiki/HighAvailability. |
9235edc2 | 1957 | The development of the High Availability functionality was sponsored by |
d101a61f MW |
1958 | secunet Security Networks AG. |
1959 | ||
dd8cb2b0 AS |
1960 | - Added IKEv1 and IKEv2 configuration support for the AES-GMAC |
1961 | authentication-only ESP cipher. Our aes_gmac kernel patch or a Linux | |
1962 | 2.6.34 kernel is required to make AES-GMAC available via the XFRM | |
1963 | kernel interface. | |
1964 | ||
4590260b MW |
1965 | - Added support for Diffie-Hellman groups 22, 23 and 24 to the gmp, gcrypt |
1966 | and openssl plugins, usable by both pluto and charon. The new proposal | |
1967 | keywords are modp1024s160, modp2048s224 and modp2048s256. Thanks to Joy Latten | |
1968 | from IBM for his contribution. | |
1969 | ||
9235edc2 AS |
1970 | - The IKEv1 pluto daemon supports RAM-based virtual IP pools using |
1971 | the rightsourceip directive with a subnet from which addresses | |
1972 | are allocated. | |
1973 | ||
d6457833 AS |
1974 | - The ipsec pki --gen and --pub commands now allow the output of |
1975 | private and public keys in PEM format using the --outform pem | |
1976 | command line option. | |
1977 | ||
2d097a0b MW |
1978 | - The new DHCP plugin queries virtual IP addresses for clients from a DHCP |
1979 | server using broadcasts, or a defined server using the | |
1980 | charon.plugins.dhcp.server strongswan.conf option. DNS/WINS server information | |
1981 | is additionally served to clients if the DHCP server provides such | |
1982 | information. The plugin is used in ipsec.conf configurations having | |
1983 | rightsourceip set to %dhcp. | |
1984 | ||
6d6994c6 MW |
1985 | - A new plugin called farp fakes ARP responses for virtual IP addresses |
1986 | handed out to clients from the IKEv2 daemon charon. The plugin lets a | |
89bf11d2 | 1987 | road-warrior act as a client on the local LAN if it uses a virtual IP |
6d6994c6 MW |
1988 | from the responders subnet, e.g. acquired using the DHCP plugin. |
1989 | ||
00c60592 MW |
1990 | - The existing IKEv2 socket implementations have been migrated to the |
1991 | socket-default and the socket-raw plugins. The new socket-dynamic plugin | |
1992 | binds sockets dynamically to ports configured via the left-/rightikeport | |
1993 | ipsec.conf connection parameters. | |
1994 | ||
3e6b50ed MW |
1995 | - The android charon plugin stores received DNS server information as "net.dns" |
1996 | system properties, as used by the Android platform. | |
00c60592 | 1997 | |
d6457833 | 1998 | |
4c68a85a AS |
1999 | strongswan-4.3.6 |
2000 | ---------------- | |
2001 | ||
cdad91de | 2002 | - The IKEv2 daemon supports RFC 3779 IP address block constraints |
e98a4d80 AS |
2003 | carried as a critical X.509v3 extension in the peer certificate. |
2004 | ||
a7155606 AS |
2005 | - The ipsec pool --add|del dns|nbns command manages DNS and NBNS name |
2006 | server entries that are sent via the IKEv1 Mode Config or IKEv2 | |
2007 | Configuration Payload to remote clients. | |
2008 | ||
f721e0fb AS |
2009 | - The Camellia cipher can be used as an IKEv1 encryption algorithm. |
2010 | ||
4c68a85a AS |
2011 | - The IKEv1 and IKEV2 daemons now check certificate path length constraints. |
2012 | ||
909c0c3d MW |
2013 | - The new ipsec.conf conn option "inactivity" closes a CHILD_SA if no traffic |
2014 | was sent or received within the given interval. To close the complete IKE_SA | |
2015 | if its only CHILD_SA was inactive, set the global strongswan.conf option | |
aa9eeb5d MW |
2016 | "charon.inactivity_close_ike" to yes. |
2017 | ||
44e41c4c AS |
2018 | - More detailed IKEv2 EAP payload information in debug output |
2019 | ||
2b2c69e9 | 2020 | - IKEv2 EAP-SIM and EAP-AKA share joint libsimaka library |
44e41c4c | 2021 | |
52fd0ef9 MW |
2022 | - Added required userland changes for proper SHA256 and SHA384/512 in ESP that |
2023 | will be introduced with Linux 2.6.33. The "sha256"/"sha2_256" keyword now | |
2024 | configures the kernel with 128 bit truncation, not the non-standard 96 | |
2025 | bit truncation used by previous releases. To use the old 96 bit truncation | |
2026 | scheme, the new "sha256_96" proposal keyword has been introduced. | |
4c68a85a | 2027 | |
2b2c69e9 MW |
2028 | - Fixed IPComp in tunnel mode, stripping out the duplicated outer header. This |
2029 | change makes IPcomp tunnel mode connections incompatible with previous | |
2030 | releases; disable compression on such tunnels. | |
2031 | ||
6ec949e0 MW |
2032 | - Fixed BEET mode connections on recent kernels by installing SAs with |
2033 | appropriate traffic selectors, based on a patch by Michael Rossberg. | |
2034 | ||
cdad91de MW |
2035 | - Using extensions (such as BEET mode) and crypto algorithms (such as twofish, |
2036 | serpent, sha256_96) allocated in the private use space now require that we | |
2037 | know its meaning, i.e. we are talking to strongSwan. Use the new | |
2038 | "charon.send_vendor_id" option in strongswan.conf to let the remote peer know | |
2039 | this is the case. | |
2040 | ||
aca9f9ab MW |
2041 | - Experimental support for draft-eronen-ipsec-ikev2-eap-auth, where the |
2042 | responder omits public key authentication in favor of a mutual authentication | |
2043 | method. To enable EAP-only authentication, set rightauth=eap on the responder | |
2044 | to rely only on the MSK constructed AUTH payload. This not-yet standardized | |
2045 | extension requires the strongSwan vendor ID introduced above. | |
2046 | ||
0a975307 AS |
2047 | - The IKEv1 daemon ignores the Juniper SRX notification type 40001, thus |
2048 | allowing interoperability. | |
2049 | ||
2050 | ||
b6b90b68 MW |
2051 | strongswan-4.3.5 |
2052 | ---------------- | |
2053 | ||
628f023d AS |
2054 | - The IKEv1 pluto daemon can now use SQL-based address pools to deal out |
2055 | virtual IP addresses as a Mode Config server. The pool capability has been | |
2056 | migrated from charon's sql plugin to a new attr-sql plugin which is loaded | |
b42bfc79 | 2057 | by libstrongswan and which can be used by both daemons either with a SQLite |
628f023d AS |
2058 | or MySQL database and the corresponding plugin. |
2059 | ||
b42bfc79 MW |
2060 | - Plugin names have been streamlined: EAP plugins now have a dash after eap |
2061 | (e.g. eap-sim), as it is used with the --enable-eap-sim ./configure option. | |
2062 | Plugin configuration sections in strongswan.conf now use the same name as the | |
2063 | plugin itself (i.e. with a dash). Make sure to update "load" directives and | |
2064 | the affected plugin sections in existing strongswan.conf files. | |
2065 | ||
d245f5cf AS |
2066 | - The private/public key parsing and encoding has been split up into |
2067 | separate pkcs1, pgp, pem and dnskey plugins. The public key implementation | |
2068 | plugins gmp, gcrypt and openssl can all make use of them. | |
b6b90b68 | 2069 | |
55b045ab MW |
2070 | - The EAP-AKA plugin can use different backends for USIM/quintuplet |
2071 | calculations, very similar to the EAP-SIM plugin. The existing 3GPP2 software | |
2072 | implementation has been migrated to a separate plugin. | |
2073 | ||
d245f5cf | 2074 | - The IKEv2 daemon charon gained basic PGP support. It can use locally installed |
b6b90b68 MW |
2075 | peer certificates and can issue signatures based on RSA private keys. |
2076 | ||
2077 | - The new 'ipsec pki' tool provides a set of commands to maintain a public | |
2078 | key infrastructure. It currently supports operations to create RSA and ECDSA | |
2079 | private/public keys, calculate fingerprints and issue or verify certificates. | |
2080 | ||
2081 | - Charon uses a monotonic time source for statistics and job queueing, behaving | |
2082 | correctly if the system time changes (e.g. when using NTP). | |
2083 | ||
2084 | - In addition to time based rekeying, charon supports IPsec SA lifetimes based | |
1003cf23 | 2085 | on processed volume or number of packets. They new ipsec.conf parameters |
b6b90b68 MW |
2086 | 'lifetime' (an alias to 'keylife'), 'lifebytes' and 'lifepackets' handle |
2087 | SA timeouts, while the parameters 'margintime' (an alias to rekeymargin), | |
2088 | 'marginbytes' and 'marginpackets' trigger the rekeying before a SA expires. | |
2089 | The existing parameter 'rekeyfuzz' affects all margins. | |
2090 | ||
85af7a89 MW |
2091 | - If no CA/Gateway certificate is specified in the NetworkManager plugin, |
2092 | charon uses a set of trusted root certificates preinstalled by distributions. | |
2093 | The directory containing CA certificates can be specified using the | |
2094 | --with-nm-ca-dir=path configure option. | |
2095 | ||
b80fa9ca | 2096 | - Fixed the encoding of the Email relative distinguished name in left|rightid |
509f70c1 | 2097 | statements. |
b80fa9ca | 2098 | |
509f70c1 AS |
2099 | - Fixed the broken parsing of PKCS#7 wrapped certificates by the pluto daemon. |
2100 | ||
2101 | - Fixed smartcard-based authentication in the pluto daemon which was broken by | |
2102 | the ECDSA support introduced with the 4.3.2 release. | |
2103 | ||
cea4bd8f AS |
2104 | - A patch contributed by Heiko Hund fixes mixed IPv6 in IPv4 and vice versa |
2105 | tunnels established with the IKEv1 pluto daemon. | |
2106 | ||
509f70c1 AS |
2107 | - The pluto daemon now uses the libstrongswan x509 plugin for certificates and |
2108 | CRls and the struct id type was replaced by identification_t used by charon | |
2109 | and the libstrongswan library. | |
18060241 | 2110 | |
85af7a89 | 2111 | |
430dd08a AS |
2112 | strongswan-4.3.4 |
2113 | ---------------- | |
2114 | ||
2115 | - IKEv2 charon daemon ported to FreeBSD and Mac OS X. Installation details can | |
2116 | be found on wiki.strongswan.org. | |
2117 | ||
2118 | - ipsec statusall shows the number of bytes transmitted and received over | |
2119 | ESP connections configured by the IKEv2 charon daemon. | |
2120 | ||
2121 | - The IKEv2 charon daemon supports include files in ipsec.secrets. | |
2122 | ||
2123 | ||
1c7f456a AS |
2124 | strongswan-4.3.3 |
2125 | ---------------- | |
2126 | ||
aa74d705 AS |
2127 | - The configuration option --enable-integrity-test plus the strongswan.conf |
2128 | option libstrongswan.integrity_test = yes activate integrity tests | |
2129 | of the IKE daemons charon and pluto, libstrongswan and all loaded | |
2130 | plugins. Thus dynamic library misconfigurations and non-malicious file | |
2131 | manipulations can be reliably detected. | |
2132 | ||
1c7f456a AS |
2133 | - The new default setting libstrongswan.ecp_x_coordinate_only=yes allows |
2134 | IKEv1 interoperability with MS Windows using the ECP DH groups 19 and 20. | |
2135 | ||
2136 | - The IKEv1 pluto daemon now supports the AES-CCM and AES-GCM ESP | |
2137 | authenticated encryption algorithms. | |
2138 | ||
aa74d705 AS |
2139 | - The IKEv1 pluto daemon now supports V4 OpenPGP keys. |
2140 | ||
2141 | - The RDN parser vulnerability discovered by Orange Labs research team | |
2142 | was not completely fixed in version 4.3.2. Some more modifications | |
2143 | had to be applied to the asn1_length() function to make it robust. | |
2144 | ||
1c7f456a | 2145 | |
80c0710c MW |
2146 | strongswan-4.3.2 |
2147 | ---------------- | |
2148 | ||
2149 | - The new gcrypt plugin provides symmetric cipher, hasher, RNG, Diffie-Hellman | |
2150 | and RSA crypto primitives using the LGPL licensed GNU gcrypt library. | |
2151 | ||
2152 | - libstrongswan features an integrated crypto selftest framework for registered | |
2153 | algorithms. The test-vector plugin provides a first set of test vectors and | |
2154 | allows pluto and charon to rely on tested crypto algorithms. | |
2155 | ||
b32af120 AS |
2156 | - pluto can now use all libstrongswan plugins with the exception of x509 and xcbc. |
2157 | Thanks to the openssl plugin, the ECP Diffie-Hellman groups 19, 20, 21, 25, and | |
2158 | 26 as well as ECDSA-256, ECDSA-384, and ECDSA-521 authentication can be used | |
2159 | with IKEv1. | |
126f2130 AS |
2160 | |
2161 | - Applying their fuzzing tool, the Orange Labs vulnerability research team found | |
2162 | another two DoS vulnerabilities, one in the rather old ASN.1 parser of Relative | |
2163 | Distinguished Names (RDNs) and a second one in the conversion of ASN.1 UTCTIME | |
2164 | and GENERALIZEDTIME strings to a time_t value. | |
b6b90b68 | 2165 | |
b32af120 | 2166 | |
3bf7c249 MW |
2167 | strongswan-4.3.1 |
2168 | ---------------- | |
2169 | ||
2170 | - The nm plugin now passes DNS/NBNS server information to NetworkManager, | |
09dbca9f | 2171 | allowing a gateway administrator to set DNS/NBNS configuration on clients |
3bf7c249 MW |
2172 | dynamically. |
2173 | ||
09dbca9f MW |
2174 | - The nm plugin also accepts CA certificates for gateway authentication. If |
2175 | a CA certificate is configured, strongSwan uses the entered gateway address | |
b3ab7a48 | 2176 | as its identity, requiring the gateways certificate to contain the same as |
09dbca9f MW |
2177 | subjectAltName. This allows a gateway administrator to deploy the same |
2178 | certificates to Windows 7 and NetworkManager clients. | |
047b2e42 | 2179 | |
050cc582 AS |
2180 | - The command ipsec purgeike deletes IKEv2 SAs that don't have a CHILD SA. |
2181 | The command ipsec down <conn>{n} deletes CHILD SA instance n of connection | |
2182 | <conn> whereas ipsec down <conn>{*} deletes all CHILD SA instances. | |
2183 | The command ipsec down <conn>[n] deletes IKE SA instance n of connection | |
2184 | <conn> plus dependent CHILD SAs whereas ipsec down <conn>[*] deletes all | |
2185 | IKE SA instances of connection <conn>. | |
2186 | ||
09dbca9f | 2187 | - Fixed a regression introduced in 4.3.0 where EAP authentication calculated |
047b2e42 MW |
2188 | the AUTH payload incorrectly. Further, the EAP-MSCHAPv2 MSK key derivation |
2189 | has been updated to be compatible with the Windows 7 Release Candidate. | |
2190 | ||
2191 | - Refactored installation of triggering policies. Routed policies are handled | |
2192 | outside of IKE_SAs to keep them installed in any case. A tunnel gets | |
2193 | established only once, even if initiation is delayed due network outages. | |
2194 | ||
050cc582 AS |
2195 | - Improved the handling of multiple acquire signals triggered by the kernel. |
2196 | ||
2197 | - Fixed two DoS vulnerabilities in the charon daemon that were discovered by | |
2198 | fuzzing techniques: 1) Sending a malformed IKE_SA_INIT request leaved an | |
2199 | incomplete state which caused a null pointer dereference if a subsequent | |
2200 | CREATE_CHILD_SA request was sent. 2) Sending an IKE_AUTH request with either | |
17c99722 | 2201 | a missing TSi or TSr payload caused a null pointer dereference because the |
b6b90b68 | 2202 | checks for TSi and TSr were interchanged. The IKEv2 fuzzer used was |
f3bb1bd0 | 2203 | developed by the Orange Labs vulnerability research team. The tool was |
050cc582 AS |
2204 | initially written by Gabriel Campana and is now maintained by Laurent Butti. |
2205 | ||
047b2e42 MW |
2206 | - Added support for AES counter mode in ESP in IKEv2 using the proposal |
2207 | keywords aes128ctr, aes192ctr and aes256ctr. | |
2208 | ||
d44fd821 | 2209 | - Further progress in refactoring pluto: Use of the curl and ldap plugins |
050cc582 AS |
2210 | for fetching crls and OCSP. Use of the random plugin to get keying material |
2211 | from /dev/random or /dev/urandom. Use of the openssl plugin as an alternative | |
d44fd821 | 2212 | to the aes, des, sha1, sha2, and md5 plugins. The blowfish, twofish, and |
050cc582 | 2213 | serpent encryption plugins are now optional and are not enabled by default. |

2217 | ---------------- | |
2218 | ||
81fc8e5f MW |
2219 | - Support for the IKEv2 Multiple Authentication Exchanges extension (RFC4739). |
2220 | Initiators and responders can use several authentication rounds (e.g. RSA | |
2221 | followed by EAP) to authenticate. The new ipsec.conf leftauth/rightauth and | |
2222 | leftauth2/rightauth2 parameters define own authentication rounds or setup | |
b3ab7a48 | 2223 | constraints for the remote peer. See the ipsec.conf man page for more details. |
81fc8e5f MW |
2224 | |
2225 | - If glibc printf hooks (register_printf_function) are not available, | |
2226 | strongSwan can use the vstr string library to run on non-glibc systems. | |
2227 | ||
558c89e7 AS |
2228 | - The IKEv2 charon daemon can now configure the ESP CAMELLIA-CBC cipher |
2229 | (esp=camellia128|192|256). | |
247e665a | 2230 | |
558c89e7 AS |
2231 | - Refactored the pluto and scepclient code to use basic functions (memory |
2232 | allocation, leak detective, chunk handling, printf_hooks, strongswan.conf | |
2233 | attributes, ASN.1 parser, etc.) from the libstrongswan library. | |
b752f873 | 2234 | |
558c89e7 AS |
2235 | - Up to two DNS and WINS servers to be sent via IKEv1 ModeConfig can be |
2236 | configured in the pluto section of strongswan.conf. | |

2240 | ----------------- | |
2241 | ||
22180558 | 2242 | - The new server-side EAP RADIUS plugin (--enable-eap-radius) |
f3bb1bd0 | 2243 | relays EAP messages to and from a RADIUS server. Successfully |
22180558 AS |
2244 | tested with with a freeradius server using EAP-MD5 and EAP-SIM. |
2245 | ||
79b27294 AS |
2246 | - A vulnerability in the Dead Peer Detection (RFC 3706) code was found by |
2247 | Gerd v. Egidy <gerd.von.egidy@intra2net.com> of Intra2net AG affecting | |
2248 | all Openswan and strongSwan releases. A malicious (or expired ISAKMP) | |
2249 | R_U_THERE or R_U_THERE_ACK Dead Peer Detection packet can cause the | |
2250 | pluto IKE daemon to crash and restart. No authentication or encryption | |
2251 | is required to trigger this bug. One spoofed UDP packet can cause the | |
2252 | pluto IKE daemon to restart and be unresponsive for a few seconds while | |
2253 | restarting. This DPD null state vulnerability has been officially | |
2254 | registered as CVE-2009-0790 and is fixed by this release. | |
2255 | ||
22180558 AS |
2256 | - ASN.1 to time_t conversion caused a time wrap-around for |
2257 | dates after Jan 18 03:14:07 UTC 2038 on 32-bit platforms. | |
2258 | As a workaround such dates are set to the maximum representable | |
2259 | time, i.e. Jan 19 03:14:07 UTC 2038. | |
2260 | ||
2261 | - Distinguished Names containing wildcards (*) are not sent in the | |

2285 | either by --enable-md4 or --enable-openssl. | |
2286 | ||
2287 | - Assignment of up to two DNS and up to two WINS servers to peers via | |
b6b90b68 | 2288 | the IKEv2 Configuration Payload (CP). The IPv4 or IPv6 nameserver |
bfde75ee AS |
2289 | addresses are defined in strongswan.conf. |
2290 | ||
2291 | - The strongSwan applet for the Gnome NetworkManager is now built and | |
2292 | distributed as a separate tarball under the name NetworkManager-strongswan. | |

2306 | ----------------- | |
2307 | ||
2308 | - Several performance improvements to handle thousands of tunnels with almost | |
2309 | linear upscaling. All relevant data structures have been replaced by faster | |
2310 | counterparts with better lookup times. | |
2311 | ||
2312 | - Better parallelization to run charon on multiple cores. Due to improved | |
1003cf23 | 2313 | resource locking and other optimizations the daemon can take full |
4856241c MW |
2314 | advantage of 16 or even more cores. |
2315 | ||
2316 | - The load-tester plugin can use a NULL Diffie-Hellman group and simulate | |
2317 | unique identities and certificates by signing peer certificates using a CA | |
2318 | on the fly. | |
2319 | ||
2320 | - The redesigned stroke in-memory IP pool handles leases. The "ipsec leases" | |
2321 | command queries assigned leases. | |
2322 | ||
2323 | - Added support for smartcards in charon by using the ENGINE API provided by | |
2324 | OpenSSL, based on patches by Michael Roßberg. | |
2325 | ||
2326 | - The Padlock plugin supports the hardware RNG found on VIA CPUs to provide a | |
2327 | reliable source of randomness. | |

2333 | syslog facilities or to files using fine-grained log levels for each target. | |
73937bd8 MW |
2334 | |
2335 | - Load testing plugin to do stress testing of the IKEv2 daemon against self | |
2336 | or another host. Found and fixed issues during tests in the multi-threaded | |
2337 | use of the OpenSSL plugin. | |
2338 | ||
2339 | - Added profiling code to synchronization primitives to find bottlenecks if | |
7bdc931e | 2340 | running on multiple cores. Found and fixed an issue where parts of the |
73937bd8 MW |
2341 | Diffie-Hellman calculation acquired an exclusive lock. This greatly improves |
2342 | parallelization to multiple cores. | |
2343 | ||
509e07c5 AS |
2344 | - updown script invocation has been separated into a plugin of its own to |
2345 | further slim down the daemon core. | |
73937bd8 | 2346 | |
509e07c5 | 2347 | - Separated IKE_SA/CHILD_SA key derivation process into a closed system, |
7bdc931e | 2348 | allowing future implementations to use a secured environment in e.g. kernel |
73937bd8 MW |
2349 | memory or hardware. |
2350 | ||
509e07c5 AS |
2351 | - The kernel interface of charon has been modularized. XFRM NETLINK (default) |
2352 | and PFKEY (--enable-kernel-pfkey) interface plugins for the native IPsec | |
2353 | stack of the Linux 2.6 kernel as well as a PFKEY interface for the KLIPS | |
2354 | IPsec stack (--enable-kernel-klips) are provided. | |
2355 | ||
2356 | - Basic Mobile IPv6 support has been introduced, securing Binding Update | |
2357 | messages as well as tunneled traffic between Mobile Node and Home Agent. | |
2358 | The installpolicy=no option allows peaceful cooperation with a dominant | |
2359 | mip6d daemon and the new type=transport_proxy implements the special MIPv6 | |
2360 | IPsec transport proxy mode where the IKEv2 daemon uses the Care-of-Address | |
f3bb1bd0 | 2361 | but the IPsec SA is set up for the Home Address. |
7bdc931e | 2362 | |
4dc0dce8 AS |
2363 | - Implemented migration of Mobile IPv6 connections using the KMADDRESS |
2364 | field contained in XFRM_MSG_MIGRATE messages sent by the mip6d daemon | |
2365 | via the Linux 2.6.28 (or appropriately patched) kernel. | |

2368 | strongswan-4.2.8 |
2369 | ---------------- | |
2370 | ||
5dadb16e | 2371 | - IKEv2 charon daemon supports authentication based on raw public keys |
e39b271b AS |
2372 | stored in the SQL database backend. The ipsec listpubkeys command |
2373 | lists the available raw public keys via the stroke interface. | |
2374 | ||
4f0241e6 MW |
2375 | - Several MOBIKE improvements: Detect changes in NAT mappings in DPD exchanges, |
2376 | handle events if kernel detects NAT mapping changes in UDP-encapsulated | |
2db6d5b8 | 2377 | ESP packets (requires kernel patch), reuse old addresses in MOBIKE updates as |
4f0241e6 MW |
2378 | long as possible and other fixes. |
2379 | ||
5dadb16e AS |
2380 | - Fixed a bug in addr_in_subnet() which caused insertion of wrong source |
2381 | routes for destination subnets having netwmasks not being a multiple of 8 bits. | |
2382 | Thanks go to Wolfgang Steudel, TU Ilmenau for reporting this bug. | |

2385 | strongswan-4.2.7 |
2386 | ---------------- | |
2387 | ||
b37cda82 AS |
2388 | - Fixed a Denial-of-Service vulnerability where an IKE_SA_INIT message with |
2389 | a KE payload containing zeroes only can cause a crash of the IKEv2 charon | |
2390 | daemon due to a NULL pointer returned by the mpz_export() function of the | |
2391 | GNU Multiprecision Library (GMP). Thanks go to Mu Dynamics Research Labs | |
b6b90b68 | 2392 | for making us aware of this problem. |
b37cda82 | 2393 | |
b6b90b68 | 2394 | - The new agent plugin provides a private key implementation on top of an |
e376d75f MW |
2395 | ssh-agent. |
2396 | ||
2397 | - The NetworkManager plugin has been extended to support certificate client | |
b1f47854 | 2398 | authentication using RSA keys loaded from a file or using ssh-agent. |
e376d75f MW |
2399 | |
2400 | - Daemon capability dropping has been ported to libcap and must be enabled | |
2401 | explicitly --with-capabilities=libcap. Future version will support the | |
2402 | newer libcap2 library. | |
2403 | ||

2409 | ---------------- | |
2410 | ||
609166f4 MW |
2411 | - A NetworkManager plugin allows GUI-based configuration of road-warrior |
2412 | clients in a simple way. It features X509 based gateway authentication | |
2413 | and EAP client authentication, tunnel setup/teardown and storing passwords | |
2414 | in the Gnome Keyring. | |
2415 | ||
2416 | - A new EAP-GTC plugin implements draft-sheffer-ikev2-gtc-00.txt and allows | |
2417 | username/password authentication against any PAM service on the gateway. | |
b6b90b68 | 2418 | The new EAP method interacts nicely with the NetworkManager plugin and allows |
609166f4 MW |
2419 | client authentication against e.g. LDAP. |
2420 | ||
2421 | - Improved support for the EAP-Identity method. The new ipsec.conf eap_identity | |
2422 | parameter defines an additional identity to pass to the server in EAP | |
2423 | authentication. | |
2424 | ||
9f9d6ece AS |
2425 | - The "ipsec statusall" command now lists CA restrictions, EAP |
2426 | authentication types and EAP identities. | |
2427 | ||
2428 | - Fixed two multithreading deadlocks occurring when starting up | |
2429 | several hundred tunnels concurrently. | |
2430 | ||

8124e491 AS |
2439 | |
2440 | - Improved the performance of the SQL-based virtual IP address pool | |
2441 | by introducing an additional addresses table. The leases table | |
2442 | storing only history information has become optional and can be | |
2443 | disabled by setting charon.plugins.sql.lease_history = no in | |
2444 | strongswan.conf. | |
2445 | ||
eb0cc338 | 2446 | - The XFRM_STATE_AF_UNSPEC flag added to xfrm.h allows IPv4-over-IPv6 |
de5f70e7 | 2447 | and IPv6-over-IPv4 tunnels with the 2.6.26 and later Linux kernels. |
eb0cc338 | 2448 | |

2490 | strongswan-4.2.2 |
2491 | ---------------- | |
2492 | ||
a57cd446 AS |
2493 | - Plugins for libstrongswan and charon can optionally be loaded according |
2494 | to a configuration in strongswan.conf. Most components provide a | |
7f491111 | 2495 | "load = " option followed by a space separated list of plugins to load. |
a57cd446 AS |
2496 | This allows e.g. the fallback from a hardware crypto accelerator to |
2497 | to software-based crypto plugins. | |
7f491111 MW |
2498 | |
2499 | - Charons SQL plugin has been extended by a virtual IP address pool. | |
a57cd446 AS |
2500 | Configurations with a rightsourceip=%poolname setting query a SQLite or |
2501 | MySQL database for leases. The "ipsec pool" command helps in administrating | |
2502 | the pool database. See ipsec pool --help for the available options | |
2503 | ||
2504 | - The Authenticated Encryption Algorithms AES-CCM-8/12/16 and AES-GCM-8/12/16 | |
b6b90b68 | 2505 | for ESP are now supported starting with the Linux 2.6.25 kernel. The |
a57cd446 AS |
2506 | syntax is e.g. esp=aes128ccm12 or esp=aes256gcm16. |

2509 | strongswan-4.2.1 |
2510 | ---------------- | |
2511 | ||
c306dfb1 | 2512 | - Support for "Hash and URL" encoded certificate payloads has been implemented |
b1f8fc0c TB |
2513 | in the IKEv2 daemon charon. Using the "certuribase" option of a CA section |
2514 | allows to assign a base URL to all certificates issued by the specified CA. | |
2515 | The final URL is then built by concatenating that base and the hex encoded | |
2516 | SHA1 hash of the DER encoded certificate. Note that this feature is disabled | |
2517 | by default and must be enabled using the option "charon.hash_and_url". | |
5c5d67d6 | 2518 | |
58caabf7 MW |
2519 | - The IKEv2 daemon charon now supports the "uniqueids" option to close multiple |
2520 | IKE_SAs with the same peer. The option value "keep" prefers existing | |
2521 | connection setups over new ones, where the value "replace" replaces existing | |
2522 | connections. | |
b6b90b68 | 2523 | |
f3bb1bd0 | 2524 | - The crypto factory in libstrongswan additionally supports random number |
58caabf7 | 2525 | generators, plugins may provide other sources of randomness. The default |
c306dfb1 | 2526 | plugin reads raw random data from /dev/(u)random. |
58caabf7 | 2527 | |
b6b90b68 | 2528 | - Extended the credential framework by a caching option to allow plugins |
58caabf7 | 2529 | persistent caching of fetched credentials. The "cachecrl" option has been |
c306dfb1 | 2530 | re-implemented. |
58caabf7 MW |
2531 | |
2532 | - The new trustchain verification introduced in 4.2.0 has been parallelized. | |
2533 | Threads fetching CRL or OCSP information no longer block other threads. | |
5c5d67d6 | 2534 | |
58caabf7 MW |
2535 | - A new IKEv2 configuration attribute framework has been introduced allowing |
2536 | plugins to provide virtual IP addresses, and in the future, other | |
2537 | configuration attribute services (e.g. DNS/WINS servers). | |
5c5d67d6 | 2538 | |
466abb49 | 2539 | - The stroke plugin has been extended to provide virtual IP addresses from |
58caabf7 MW |
2540 | a pool defined in ipsec.conf. The "rightsourceip" parameter now accepts |
2541 | address pools in CIDR notation (e.g. 10.1.1.0/24). The parameter also accepts | |
2542 | the value "%poolname", where "poolname" identifies a pool provided by a | |
466abb49 | 2543 | separate plugin. |
58caabf7 | 2544 | |
c306dfb1 | 2545 | - Fixed compilation on uClibc and a couple of other minor bugs. |
58caabf7 | 2546 | |
c306dfb1 | 2547 | - Set DPD defaults in ipsec starter to dpd_delay=30s and dpd_timeout=150s. |
466abb49 AS |
2548 | |
2549 | - The IKEv1 pluto daemon now supports the ESP encryption algorithm CAMELLIA | |
c306dfb1 | 2550 | with key lengths of 128, 192, and 256 bits, as well as the authentication |
466abb49 AS |
2551 | algorithm AES_XCBC_MAC. Configuration example: esp=camellia192-aesxcbc. |

16f5dacd MW |
2557 | - libstrongswan has been modularized to attach crypto algorithms, |
2558 | credential implementations (keys, certificates) and fetchers dynamically | |
2559 | through plugins. Existing code has been ported to plugins: | |
2560 | - RSA/Diffie-Hellman implementation using the GNU Multi Precision library | |
2561 | - X509 certificate system supporting CRLs, OCSP and attribute certificates | |
2562 | - Multiple plugins providing crypto algorithms in software | |
2563 | - CURL and OpenLDAP fetcher | |
a11ea97d | 2564 | |

2565 | - libstrongswan gained a relational database API which uses pluggable database |
2566 | providers. Plugins for MySQL and SQLite are available. | |
2567 | ||
2568 | - The IKEv2 keying daemon charon is more extensible. Generic plugins may provide | |
2569 | connection configuration, credentials and EAP methods or control the daemon. | |
2570 | Existing code has been ported to plugins: | |
2571 | - EAP-AKA, EAP-SIM, EAP-MD5 and EAP-Identity | |
2572 | - stroke configuration, credential and control (compatible to pluto) | |
2573 | - XML bases management protocol to control and query the daemon | |
2574 | The following new plugins are available: | |
2575 | - An experimental SQL configuration, credential and logging plugin on | |
2576 | top of either MySQL or SQLite | |
2577 | - A unit testing plugin to run tests at daemon startup | |
2578 | ||
2579 | - The authentication and credential framework in charon has been heavily | |
2580 | refactored to support modular credential providers, proper | |
2581 | CERTREQ/CERT payload exchanges and extensible authorization rules. | |
2582 | ||
89bd016e | 2583 | - The framework of strongSwan Manager has evolved to the web application |
16f5dacd MW |
2584 | framework libfast (FastCGI Application Server w/ Templates) and is usable |
2585 | by other applications. | |

2589 | ----------------- | |
fb6d76cd | 2590 | |
a561f74d AS |
2591 | - IKE rekeying in NAT situations did not inherit the NAT conditions |
2592 | to the rekeyed IKE_SA so that the UDP encapsulation was lost with | |
2593 | the next CHILD_SA rekeying. | |
2594 | ||
2595 | - Wrong type definition of the next_payload variable in id_payload.c | |
b6b90b68 | 2596 | caused an INVALID_SYNTAX error on PowerPC platforms. |
fb6d76cd | 2597 | |
e6b50b3f AS |
2598 | - Implemented IKEv2 EAP-SIM server and client test modules that use |
2599 | triplets stored in a file. For details on the configuration see | |
2600 | the scenario 'ikev2/rw-eap-sim-rsa'. | |

83e0d841 AS |
2603 | strongswan-4.1.10 |
2604 | ----------------- | |
2605 | ||
2606 | - Fixed error in the ordering of the certinfo_t records in the ocsp cache that | |
b6b90b68 | 2607 | caused multiple entries of the same serial number to be created. |
83e0d841 | 2608 | |
fdc7c943 MW |
2609 | - Implementation of a simple EAP-MD5 module which provides CHAP |
2610 | authentication. This may be interesting in conjunction with certificate | |
2611 | based server authentication, as weak passwords can't be brute forced | |
2612 | (in contradiction to traditional IKEv2 PSK). | |
2613 | ||
2614 | - A complete software based implementation of EAP-AKA, using algorithms | |
2615 | specified in 3GPP2 (S.S0055). This implementation does not use an USIM, | |
2616 | but reads the secrets from ipsec.secrets. Make sure to read eap_aka.h | |
2617 | before using it. | |
2618 | ||
2619 | - Support for vendor specific EAP methods using Expanded EAP types. The | |
b6b90b68 | 2620 | interface to EAP modules has been slightly changed, so make sure to |
fdc7c943 | 2621 | check the changes if you're already rolling your own modules. |

2624 | strongswan-4.1.9 |
2625 | ---------------- | |
2626 | ||
800b3356 AS |
2627 | - The default _updown script now dynamically inserts and removes ip6tables |
2628 | firewall rules if leftfirewall=yes is set in IPv6 connections. New IPv6 | |
2629 | net-net and roadwarrior (PSK/RSA) scenarios for both IKEv1 and IKEV2 were | |
2630 | added. | |
5076770c | 2631 | |
6f274c2a MW |
2632 | - Implemented RFC4478 repeated authentication to force EAP/Virtual-IP clients |
2633 | to reestablish an IKE_SA within a given timeframe. | |
2634 | ||
2635 | - strongSwan Manager supports configuration listing, initiation and termination | |
2636 | of IKE and CHILD_SAs. | |
2637 | ||
2638 | - Fixes and improvements to multithreading code. | |
2639 | ||
8b678ad4 | 2640 | - IKEv2 plugins have been renamed to libcharon-* to avoid naming conflicts. |
b6b90b68 | 2641 | Make sure to remove the old plugins in $libexecdir/ipsec, otherwise they get |
8b678ad4 | 2642 | loaded twice. |

b82e8231 AS |
2645 | strongswan-4.1.8 |
2646 | ---------------- | |
2647 | ||
5076770c | 2648 | - Removed recursive pthread mutexes since uClibc doesn't support them. |
b82e8231 AS |

a4a3632c AS |
2651 | strongswan-4.1.7 |
2652 | ---------------- | |
2653 | ||
2654 | - In NAT traversal situations and multiple queued Quick Modes, | |
2655 | those pending connections inserted by auto=start after the | |
2db6d5b8 | 2656 | port floating from 500 to 4500 were erroneously deleted. |
a4a3632c | 2657 | |
6e193274 | 2658 | - Added a "forceencaps" connection parameter to enforce UDP encapsulation |
078b6008 | 2659 | to surmount restrictive firewalls. NAT detection payloads are faked to |
6e193274 MW |
2660 | simulate a NAT situation and trick the other peer into NAT mode (IKEv2 only). |
2661 | ||
2662 | - Preview of strongSwan Manager, a web based configuration and monitoring | |
2663 | application. It uses a new XML control interface to query the IKEv2 daemon | |
e4a3ef2e | 2664 | (see https://wiki.strongswan.org/wiki/Manager). |
6e193274 MW |
2665 | |
2666 | - Experimental SQLite configuration backend which will provide the configuration | |
2667 | interface for strongSwan Manager in future releases. | |
2668 | ||
2669 | - Further improvements to MOBIKE support. | |
2670 | ||
a4a3632c | 2671 | |
3dcf9dbd AS |
2672 | strongswan-4.1.6 |
2673 | ---------------- | |
2674 | ||
3eac4dfd AS |
2675 | - Since some third party IKEv2 implementations run into |
2676 | problems with strongSwan announcing MOBIKE capability per | |
2677 | default, MOBIKE can be disabled on a per-connection-basis | |
2678 | using the mobike=no option. Whereas mobike=no disables the | |
2679 | sending of the MOBIKE_SUPPORTED notification and the floating | |
2680 | to UDP port 4500 with the IKE_AUTH request even if no NAT | |
2681 | situation has been detected, strongSwan will still support | |
2682 | MOBIKE acting as a responder. | |
2683 | ||
2684 | - the default ipsec routing table plus its corresponding priority | |
2685 | used for inserting source routes has been changed from 100 to 220. | |
2686 | It can be configured using the --with-ipsec-routing-table and | |
b6b90b68 MW |
2687 | --with-ipsec-routing-table-prio options. |
2688 | ||
bdc0b55b AS |
2689 | - the --enable-integrity-test configure option tests the |
2690 | integrity of the libstrongswan crypto code during the charon | |
2691 | startup. | |
b6b90b68 | 2692 | |
3eac4dfd AS |
2693 | - the --disable-xauth-vid configure option disables the sending |
2694 | of the XAUTH vendor ID. This can be used as a workaround when | |
2695 | interoperating with some Windows VPN clients that get into | |
2696 | trouble upon reception of an XAUTH VID without eXtended | |
2697 | AUTHentication having been configured. | |
b6b90b68 | 2698 | |
f872f9d1 AS |
2699 | - ipsec stroke now supports the rereadsecrets, rereadaacerts, |
2700 | rereadacerts, and listacerts options. | |
3dcf9dbd AS |
2701 | |
2702 | ||
7ad634a2 AS |
2703 | strongswan-4.1.5 |
2704 | ---------------- | |
2705 | ||
2706 | - If a DNS lookup failure occurs when resolving right=%<FQDN> | |
2707 | or right=<FQDN> combined with rightallowany=yes then the | |
2708 | connection is not updated by ipsec starter thus preventing | |
2709 | the disruption of an active IPsec connection. Only if the DNS | |
2710 | lookup successfully returns with a changed IP address the | |
2711 | corresponding connection definition is updated. | |
2712 | ||
8f5b363c MW |
2713 | - Routes installed by the keying daemons are now in a separate |
2714 | routing table with the ID 100 to avoid conflicts with the main | |
2715 | table. Route lookup for IKEv2 traffic is done in userspace to ignore | |
2716 | routes installed for IPsec, as IKE traffic shouldn't get encapsulated. | |
2717 | ||
7ad634a2 | 2718 | |
e93c68ba AS |
2719 | strongswan-4.1.4 |
2720 | ---------------- | |
2721 | ||
2722 | - The pluto IKEv1 daemon now exhibits the same behaviour as its | |
2723 | IKEv2 companion charon by inserting an explicit route via the | |
2724 | _updown script only if a sourceip exists. This is admissible | |
2725 | since routing through the IPsec tunnel is handled automatically | |
b7af55ac AS |
2726 | by NETKEY's IPsec policies. As a consequence the left|rightnexthop |
2727 | parameter is not required any more. | |
078ce348 AS |
2728 | |
2729 | - The new IKEv1 parameter right|leftallowany parameters helps to handle | |
2730 | the case where both peers possess dynamic IP addresses that are | |
2731 | usually resolved using DynDNS or a similar service. The configuration | |
2732 | ||
2733 | right=peer.foo.bar | |
2734 | rightallowany=yes | |
2735 | ||
2736 | can be used by the initiator to start up a connection to a peer | |
2737 | by resolving peer.foo.bar into the currently allocated IP address. | |
2738 | Thanks to the rightallowany flag the connection behaves later on | |
2739 | as | |
2740 | ||
53f8ac3d | 2741 | right=%any |
078ce348 AS |
2742 | |
2743 | so that the peer can rekey the connection as an initiator when his | |
1fbdab85 AS |
2744 | IP address changes. An alternative notation is |
2745 | ||
2746 | right=%peer.foo.bar | |
2747 | ||
2748 | which will implicitly set rightallowany=yes. | |
2749 | ||
2750 | - ipsec starter now fails more gracefully in the presence of parsing | |
2751 | errors. Flawed ca and conn section are discarded and pluto is started | |
2752 | if non-fatal errors only were encountered. If right=%peer.foo.bar | |
2753 | cannot be resolved by DNS then right=%any will be used so that passive | |
2754 | connections as a responder are still possible. | |
078ce348 | 2755 | |
a0a0bdd7 AS |
2756 | - The new pkcs11initargs parameter that can be placed in the |
2757 | setup config section of /etc/ipsec.conf allows the definition | |
2758 | of an argument string that is used with the PKCS#11 C_Initialize() | |
2759 | function. This non-standard feature is required by the NSS softoken | |
2760 | library. This patch was contributed by Robert Varga. | |
b6b90b68 | 2761 | |
a0a0bdd7 AS |
2762 | - Fixed a bug in ipsec starter introduced by strongswan-2.8.5 |
2763 | which caused a segmentation fault in the presence of unknown | |
2764 | or misspelt keywords in ipsec.conf. This bug fix was contributed | |
2765 | by Robert Varga. | |
2766 | ||
e3606f2b MW |
2767 | - Partial support for MOBIKE in IKEv2. The initiator acts on interface/ |
2768 | address configuration changes and updates IKE and IPsec SAs dynamically. | |
e93c68ba | 2769 | |
06651827 | 2770 | |
a3354a69 AS |
2771 | strongswan-4.1.3 |
2772 | ---------------- | |
2773 | ||
b6b90b68 | 2774 | - IKEv2 peer configuration selection now can be based on a given |
35d4809c AS |
2775 | certification authority using the rightca= statement. |
2776 | ||
2777 | - IKEv2 authentication based on RSA signatures now can handle multiple | |
41e16cf4 AS |
2778 | certificates issued for a given peer ID. This allows a smooth transition |
2779 | in the case of a peer certificate renewal. | |
a3354a69 | 2780 | |
998ca0ea MW |
2781 | - IKEv2: Support for requesting a specific virtual IP using leftsourceip on the |
2782 | client and returning requested virtual IPs using rightsourceip=%config | |
2783 | on the server. If the server does not support configuration payloads, the | |
2784 | client enforces its leftsourceip parameter. | |
2785 | ||
2786 | - The ./configure options --with-uid/--with-gid allow pluto and charon | |
2787 | to drop their privileges to a minimum and change to an other UID/GID. This | |
2788 | improves the systems security, as a possible intruder may only get the | |
2789 | CAP_NET_ADMIN capability. | |
2790 | ||
b6b90b68 | 2791 | - Further modularization of charon: Pluggable control interface and |
998ca0ea MW |
2792 | configuration backend modules provide extensibility. The control interface |
2793 | for stroke is included, and further interfaces using DBUS (NetworkManager) | |
2794 | or XML are on the way. A backend for storing configurations in the daemon | |
b6b90b68 | 2795 | is provided and more advanced backends (using e.g. a database) are trivial |
998ca0ea | 2796 | to implement. |
a3354a69 | 2797 | |
53f8ac3d TB |
2798 | - Fixed a compilation failure in libfreeswan occurring with Linux kernel |
2799 | headers > 2.6.17. | |
41e16cf4 AS |
2800 | |
2801 | ||
8ea7b96f AS |
2802 | strongswan-4.1.2 |
2803 | ---------------- | |
2804 | ||
e23d98a7 | 2805 | - Support for an additional Diffie-Hellman exchange when creating/rekeying |
37fb0355 MW |
2806 | a CHILD_SA in IKEv2 (PFS). PFS is enabled when the proposal contains a |
2807 | DH group (e.g. "esp=aes128-sha1-modp1536"). Further, DH group negotiation | |
2808 | is implemented properly for rekeying. | |
2809 | ||
2810 | - Support for the AES-XCBC-96 MAC algorithm for IPsec SAs when using IKEv2 | |
2811 | (requires linux >= 2.6.20). It is enabled using e.g. "esp=aes256-aesxcbc". | |
2812 | ||
d931f465 MW |
2813 | - Working IPv4-in-IPv6 and IPv6-in-IPv4 tunnels for linux >= 2.6.21. |
2814 | ||
37fb0355 MW |
2815 | - Added support for EAP modules which do not establish an MSK. |
2816 | ||
dfbe2a0f | 2817 | - Removed the dependencies from the /usr/include/linux/ headers by |
9f78f957 | 2818 | including xfrm.h, ipsec.h, and pfkeyv2.h in the distribution. |
b6b90b68 | 2819 | |
9f78f957 AS |
2820 | - crlNumber is now listed by ipsec listcrls |
2821 | ||
8ea7b96f AS |
2822 | - The xauth_modules.verify_secret() function now passes the |
2823 | connection name. | |
2824 | ||
e23d98a7 | 2825 | |
ed284399 MW |
2826 | strongswan-4.1.1 |
2827 | ---------------- | |
2828 | ||
2829 | - Server side cookie support. If to may IKE_SAs are in CONNECTING state, | |
2830 | cookies are enabled and protect against DoS attacks with faked source | |
2831 | addresses. Number of IKE_SAs in CONNECTING state is also limited per | |
2832 | peer address to avoid resource exhaustion. IKE_SA_INIT messages are | |
2833 | compared to properly detect retransmissions and incoming retransmits are | |
2834 | detected even if the IKE_SA is blocked (e.g. doing OCSP fetches). | |
2835 | ||
db88e37d AS |
2836 | - The IKEv2 daemon charon now supports dynamic http- and ldap-based CRL |
2837 | fetching enabled by crlcheckinterval > 0 and caching fetched CRLs | |
2838 | enabled by cachecrls=yes. | |
2839 | ||
3b4f7d92 AS |
2840 | - Added the configuration options --enable-nat-transport which enables |
2841 | the potentially insecure NAT traversal for IPsec transport mode and | |
2842 | --disable-vendor-id which disables the sending of the strongSwan | |
2843 | vendor ID. | |
2844 | ||
2845 | - Fixed a long-standing bug in the pluto IKEv1 daemon which caused | |
2846 | a segmentation fault if a malformed payload was detected in the | |
2847 | IKE MR2 message and pluto tried to send an encrypted notification | |
2848 | message. | |
2849 | ||
46b9ff68 AS |
2850 | - Added the NATT_IETF_02_N Vendor ID in order to support IKEv1 connections |
2851 | with Windows 2003 Server which uses a wrong VID hash. | |
2852 | ||
3b4f7d92 | 2853 | |
34bbd0c3 | 2854 | strongswan-4.1.0 |
cd3958f8 AS |
2855 | ---------------- |
2856 | ||
2857 | - Support of SHA2_384 hash function for protecting IKEv1 | |
2858 | negotiations and support of SHA2 signatures in X.509 certificates. | |
2859 | ||
2860 | - Fixed a serious bug in the computation of the SHA2-512 HMAC | |
2861 | function. Introduced automatic self-test of all IKEv1 hash | |
2862 | and hmac functions during pluto startup. Failure of a self-test | |
2863 | currently issues a warning only but does not exit pluto [yet]. | |
2864 | ||
9b45443d MW |
2865 | - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2. |
2866 | ||
c5d0fbb6 | 2867 | - Full support of CA information sections. ipsec listcainfos |
b6b90b68 | 2868 | now shows all collected crlDistributionPoints and OCSP |
c5d0fbb6 AS |
2869 | accessLocations. |
2870 | ||
69ed04bf AS |
2871 | - Support of the Online Certificate Status Protocol (OCSP) for IKEv2. |
2872 | This feature requires the HTTP fetching capabilities of the libcurl | |
2873 | library which must be enabled by setting the --enable-http configure | |
2874 | option. | |
2875 | ||
9b45443d MW |
2876 | - Refactored core of the IKEv2 message processing code, allowing better |
2877 | code reuse and separation. | |
2878 | ||
2879 | - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration | |
2880 | payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted | |
2881 | by the requestor and installed in a resolv.conf file. | |
2882 | ||
2883 | - The IKEv2 daemon charon installs a route for each IPsec policy to use | |
2884 | the correct source address even if an application does not explicitly | |
2885 | specify it. | |
2886 | ||
2887 | - Integrated the EAP framework into charon which loads pluggable EAP library | |
2888 | modules. The ipsec.conf parameter authby=eap initiates EAP authentication | |
2889 | on the client side, while the "eap" parameter on the server side defines | |
2890 | the EAP method to use for client authentication. | |
2891 | A generic client side EAP-Identity module and an EAP-SIM authentication | |
2892 | module using a third party card reader implementation are included. | |
2893 | ||
2894 | - Added client side support for cookies. | |
2895 | ||
2896 | - Integrated the fixes done at the IKEv2 interoperability bakeoff, including | |
2897 | strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor | |
2898 | fixes to enhance interoperability with other implementations. | |

2901 | strongswan-4.0.7 |
2902 | ---------------- | |
2903 | ||
6fdf5f44 AS |
2904 | - strongSwan now interoperates with the NCP Secure Entry Client, |
2905 | the Shrew Soft VPN Client, and the Cisco VPN client, doing both | |
2906 | XAUTH and Mode Config. | |
1c266d7d AS |
2907 | |
2908 | - UNITY attributes are now recognized and UNITY_BANNER is set | |

2912 | strongswan-4.0.6 |
2913 | ---------------- | |
2914 | ||
e38a15d4 AS |
2915 | - IKEv1: Support for extended authentication (XAUTH) in combination |
2916 | with ISAKMP Main Mode RSA or PSK authentication. Both client and | |
2917 | server side were implemented. Handling of user credentials can | |
2918 | be done by a run-time loadable XAUTH module. By default user | |
b6b90b68 MW |
2919 | credentials are stored in ipsec.secrets. |
2920 | ||
2b4405a3 MW |
2921 | - IKEv2: Support for reauthentication when rekeying |
2922 | ||
5903179b | 2923 | - IKEv2: Support for transport mode |
af87afed | 2924 | |
5903179b | 2925 | - fixed a lot of bugs related to byte order |

2930 | strongswan-4.0.5 |
2931 | ---------------- | |
2932 | ||
2933 | - IKEv1: Implementation of ModeConfig push mode via the new connection | |
2934 | keyword modeconfig=push allows interoperability with Cisco VPN gateways. | |
2935 | ||
2936 | - IKEv1: The command ipsec statusall now shows "DPD active" for all | |
2937 | ISAKMP SAs that are under active Dead Peer Detection control. | |
2938 | ||
2939 | - IKEv2: Charon's logging and debugging framework has been completely rewritten. | |
2940 | Instead of logger, special printf() functions are used to directly | |
2941 | print objects like hosts (%H) identifications (%D), certificates (%Q), | |
2942 | etc. The number of debugging levels have been reduced to: | |

2956 | strongswan-4.0.4 |
2957 | ---------------- | |
2958 | ||
2959 | - Implemented full support for IPv6-in-IPv6 tunnels. | |
2960 | ||
2961 | - Added configuration options for dead peer detection in IKEv2. dpd_action | |
2962 | types "clear", "hold" and "restart" are supported. The dpd_timeout | |
2963 | value is not used, as the normal retransmission policy applies to | |
2964 | detect dead peers. The dpd_delay parameter enables sending of empty | |
2965 | informational message to detect dead peers in case of inactivity. | |
2966 | ||
2967 | - Added support for preshared keys in IKEv2. PSK keys configured in | |
2968 | ipsec.secrets are loaded. The authby parameter specifies the authentication | |
b3ab7a48 | 2969 | method to authenticate ourself, the other peer may use PSK or RSA. |
48dc3934 MW |
2970 | |
2971 | - Changed retransmission policy to respect the keyingtries parameter. | |
2972 | ||
112ad7c3 AS |
2973 | - Added private key decryption. PEM keys encrypted with AES-128/192/256 |
2974 | or 3DES are supported. | |
48dc3934 MW |
2975 | |
2976 | - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to | |
2977 | encrypt IKE traffic. | |
2978 | ||
2979 | - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates | |
2980 | signed with such a hash algorithm. | |
2981 | ||
2982 | - Added initial support for updown scripts. The actions up-host/client and | |
2983 | down-host/client are executed. The leftfirewall=yes parameter | |
2984 | uses the default updown script to insert dynamic firewall rules, a custom | |
2985 | updown script may be specified with the leftupdown parameter. | |
2986 | ||
2987 | ||
a1310b6b MW |
2988 | strongswan-4.0.3 |
2989 | ---------------- | |
2990 | ||
2991 | - Added support for the auto=route ipsec.conf parameter and the | |
b6b90b68 MW |
2992 | ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and |
2993 | CHILD_SAs dynamically on demand when traffic is detected by the | |
a1310b6b MW |
2994 | kernel. |
2995 | ||
2996 | - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter. | |
2997 | As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only | |
2998 | new keys are generated using perfect forward secrecy. An optional flag | |
2999 | which enforces reauthentication will be implemented later. | |
3000 | ||
b425d998 AS |
3001 | - "sha" and "sha1" are now treated as synonyms in the ike= and esp= |
3002 | algorithm configuration statements. | |
3003 | ||
3004 | ||
bf4df11f AS |
3005 | strongswan-4.0.2 |
3006 | ---------------- | |
3007 | ||
623d3dcf AS |
3008 | - Full X.509 certificate trust chain verification has been implemented. |
3009 | End entity certificates can be exchanged via CERT payloads. The current | |
3010 | default is leftsendcert=always, since CERTREQ payloads are not supported | |
3011 | yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls. | |
efa40c11 | 3012 | |
b6b90b68 | 3013 | - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2 |
efa40c11 | 3014 | would offer more possibilities for traffic selection, but the Linux kernel |
b6b90b68 | 3015 | currently does not support it. That's why we stick with these simple |
efa40c11 MW |
3016 | ipsec.conf rules for now. |
3017 | ||
623d3dcf AS |
3018 | - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no |
3019 | IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear, | |
3020 | dpddelay=60s). | |
3021 | ||
efa40c11 MW |
3022 | - Initial NAT traversal support in IKEv2. Charon includes NAT detection |
3023 | notify payloads to detect NAT routers between the peers. It switches | |
3024 | to port 4500, uses UDP encapsulated ESP packets, handles peer address | |
3025 | changes gracefully and sends keep alive message periodically. | |
3026 | ||
b6b90b68 MW |
3027 | - Reimplemented IKE_SA state machine for charon, which allows simultaneous |
3028 | rekeying, more shared code, cleaner design, proper retransmission | |
efa40c11 MW |
3029 | and a more extensible code base. |
3030 | ||
cfd8b27f AS |
3031 | - The mixed PSK/RSA roadwarrior detection capability introduced by the |
3032 | strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal | |
3033 | payloads by the responder right before any defined IKE Main Mode state had | |
3034 | been established. Although any form of bad proposal syntax was being correctly | |
3035 | detected by the payload parser, the subsequent error handler didn't check | |
3036 | the state pointer before logging current state information, causing an | |
3037 | immediate crash of the pluto keying daemon due to a NULL pointer. | |
3038 | ||
bf4df11f | 3039 | |
7e81e975 MW |
3040 | strongswan-4.0.1 |
3041 | ---------------- | |
3042 | ||
b6b90b68 | 3043 | - Added algorithm selection to charon: New default algorithms for |
c15c3d4b MW |
3044 | ike=aes128-sha-modp2048, as both daemons support it. The default |
3045 | for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles | |
3046 | the ike/esp parameter the same way as pluto. As this syntax does | |
b6b90b68 | 3047 | not allow specification of a pseudo random function, the same |
c15c3d4b MW |
3048 | algorithm as for integrity is used (currently sha/md5). Supported |
3049 | algorithms for IKE: | |
3050 | Encryption: aes128, aes192, aes256 | |
3051 | Integrity/PRF: md5, sha (using hmac) | |
3052 | DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192 | |
3053 | and for ESP: | |
b6b90b68 | 3054 | Encryption: aes128, aes192, aes256, 3des, blowfish128, |
c15c3d4b MW |
3055 | blowfish192, blowfish256 |
3056 | Integrity: md5, sha1 | |
3057 | More IKE encryption algorithms will come after porting libcrypto into | |
b6b90b68 | 3058 | libstrongswan. |
f2c2d395 | 3059 | |
c15c3d4b MW |
3060 | - initial support for rekeying CHILD_SAs using IKEv2. Currently no |
3061 | perfect forward secrecy is used. The rekeying parameters rekey, | |
22ff6f57 | 3062 | rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported |
c15c3d4b MW |
3063 | when using IKEv2. WARNING: charon currently is unable to handle |
3064 | simultaneous rekeying. To avoid such a situation, use a large | |
3065 | rekeyfuzz, or even better, set rekey=no on one peer. | |
22ff6f57 | 3066 | |
7e81e975 MW |
3067 | - support for host2host, net2net, host2net (roadwarrior) tunnels |
3068 | using predefined RSA certificates (see uml scenarios for | |
3069 | configuration examples). | |
3070 | ||
f2c2d395 MW |
3071 | - new build environment featuring autotools. Features such |
3072 | as HTTP, LDAP and smartcard support may be enabled using | |
b6b90b68 | 3073 | the ./configure script. Changing install directories |
f2c2d395 MW |
3074 | is possible, too. See ./configure --help for more details. |
3075 | ||
22ff6f57 MW |
3076 | - better integration of charon with ipsec starter, which allows |
3077 | (almost) transparent operation with both daemons. charon | |
3078 | handles ipsec commands up, down, status, statusall, listall, | |
3079 | listcerts and allows proper load, reload and delete of connections | |
3080 | via ipsec starter. | |
3081 | ||
b425d998 | 3082 | |
9820c0e2 MW |
3083 | strongswan-4.0.0 |
3084 | ---------------- | |
3085 | ||
3086 | - initial support of the IKEv2 protocol. Connections in | |
b6b90b68 | 3087 | ipsec.conf designated by keyexchange=ikev2 are negotiated |
9820c0e2 MW |
3088 | by the new IKEv2 charon keying daemon whereas those marked |
3089 | by keyexchange=ikev1 or the default keyexchange=ike are | |
3090 | handled thy the IKEv1 pluto keying daemon. Currently only | |
3091 | a limited subset of functions are available with IKEv2 | |
3092 | (Default AES encryption, authentication based on locally | |
3093 | imported X.509 certificates, unencrypted private RSA keys | |
3094 | in PKCS#1 file format, limited functionality of the ipsec | |
3095 | status command). | |
3096 | ||
3097 | ||
997358a6 MW |
3098 | strongswan-2.7.0 |
3099 | ---------------- | |
3100 | ||
3101 | - the dynamic iptables rules from the _updown_x509 template | |
3102 | for KLIPS and the _updown_policy template for NETKEY have | |
3103 | been merged into the default _updown script. The existing | |
3104 | left|rightfirewall keyword causes the automatic insertion | |
3105 | and deletion of ACCEPT rules for tunneled traffic upon | |
3106 | the successful setup and teardown of an IPsec SA, respectively. | |
b3ab7a48 | 3107 | left|rightfirewall can be used with KLIPS under any Linux 2.4 |
997358a6 | 3108 | kernel or with NETKEY under a Linux kernel version >= 2.6.16 |
f3bb1bd0 | 3109 | in conjunction with iptables >= 1.3.5. For NETKEY under a Linux |
997358a6 MW |
3110 | kernel version < 2.6.16 which does not support IPsec policy |
3111 | matching yet, please continue to use a copy of the _updown_espmark | |
3112 | template loaded via the left|rightupdown keyword. | |
3113 | ||
3114 | - a new left|righthostaccess keyword has been introduced which | |
3115 | can be used in conjunction with left|rightfirewall and the | |
3116 | default _updown script. By default leftfirewall=yes inserts | |
3117 | a bi-directional iptables FORWARD rule for a local client network | |
3118 | with a netmask different from 255.255.255.255 (single host). | |
3119 | This does not allow to access the VPN gateway host via its | |
3120 | internal network interface which is part of the client subnet | |
3121 | because an iptables INPUT and OUTPUT rule would be required. | |
3122 | lefthostaccess=yes will cause this additional ACCEPT rules to | |
b6b90b68 | 3123 | be inserted. |
997358a6 MW |
3124 | |
3125 | - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal | |
3126 | payload is preparsed in order to find out whether the roadwarrior | |
3127 | requests PSK or RSA so that a matching connection candidate can | |
3128 | be found. | |
3129 | ||
3130 | ||
3131 | strongswan-2.6.4 | |
3132 | ---------------- | |
3133 | ||
3134 | - the new _updown_policy template allows ipsec policy based | |
3135 | iptables firewall rules. Required are iptables version | |
3136 | >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes | |
b6b90b68 | 3137 | the _updown_espmark template, so that no INPUT mangle rules |
997358a6 MW |
3138 | are required any more. |
3139 | ||
3140 | - added support of DPD restart mode | |
3141 | ||
3142 | - ipsec starter now allows the use of wildcards in include | |
3143 | statements as e.g. in "include /etc/my_ipsec/*.conf". | |
3144 | Patch courtesy of Matthias Haas. | |
3145 | ||
3146 | - the Netscape OID 'employeeNumber' is now recognized and can be | |
3147 | used as a Relative Distinguished Name in certificates. | |
3148 | ||
3149 | ||
3150 | strongswan-2.6.3 | |
3151 | ---------------- | |
3152 | ||
b6b90b68 | 3153 | - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec |
997358a6 MW |
3154 | command and not of ipsec setup any more. |
3155 | ||
3156 | - ipsec starter now supports AH authentication in conjunction with | |
3157 | ESP encryption. AH authentication is configured in ipsec.conf | |
3158 | via the auth=ah parameter. | |
b6b90b68 | 3159 | |
997358a6 MW |
3160 | - The command ipsec scencrypt|scdecrypt <args> is now an alias for |
3161 | ipsec whack --scencrypt|scdecrypt <args>. | |
3162 | ||
3163 | - get_sa_info() now determines for the native netkey IPsec stack | |
3164 | the exact time of the last use of an active eroute. This information | |
3165 | is used by the Dead Peer Detection algorithm and is also displayed by | |
3166 | the ipsec status command. | |
b6b90b68 | 3167 | |
997358a6 MW |
3168 | |
3169 | strongswan-2.6.2 | |
3170 | ---------------- | |
3171 | ||
3172 | - running under the native Linux 2.6 IPsec stack, the function | |
3173 | get_sa_info() is called by ipsec auto --status to display the current | |
3174 | number of transmitted bytes per IPsec SA. | |
3175 | ||
3176 | - get_sa_info() is also used by the Dead Peer Detection process to detect | |
3177 | recent ESP activity. If ESP traffic was received from the peer within | |
3178 | the last dpd_delay interval then no R_Y_THERE notification must be sent. | |
3179 | ||
3180 | - strongSwan now supports the Relative Distinguished Name "unstructuredName" | |
3181 | in ID_DER_ASN1_DN identities. The following notations are possible: | |
3182 | ||
3183 | rightid="unstructuredName=John Doe" | |
3184 | rightid="UN=John Doe" | |
3185 | ||
3186 | - fixed a long-standing bug which caused PSK-based roadwarrior connections | |
3187 | to segfault in the function id.c:same_id() called by keys.c:get_secret() | |
3188 | if an FQDN, USER_FQDN, or Key ID was defined, as in the following example. | |
3189 | ||
3190 | conn rw | |
53f8ac3d TB |
3191 | right=%any |
3192 | rightid=@foo.bar | |
3193 | authby=secret | |
997358a6 MW |
3194 | |
3195 | - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall). | |
3196 | ||
3197 | - ipsec starter didn't set host_addr and client.addr ports in whack msg. | |
3198 | ||
3199 | - in order to guarantee backwards-compatibility with the script-based | |
3200 | auto function (e.g. auto --replace), the ipsec starter scripts stores | |
3201 | the defaultroute information in the temporary file /var/run/ipsec.info. | |
3202 | ||
3203 | - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH | |
3204 | Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config | |
3205 | servers. | |
3206 | ||
3207 | - the ipsec starter now also recognizes the parameters authby=never and | |
3208 | type=passthrough|pass|drop|reject. | |
3209 | ||
3210 | ||
3211 | strongswan-2.6.1 | |
3212 | ---------------- | |
3213 | ||
3214 | - ipsec starter now supports the also parameter which allows | |
3215 | a modular structure of the connection definitions. Thus | |
3216 | "ipsec start" is now ready to replace "ipsec setup". | |
3217 | ||
3218 | ||
3219 | strongswan-2.6.0 | |
3220 | ---------------- | |
3221 | ||
3222 | - Mathieu Lafon's popular ipsec starter tool has been added to the | |
3223 | strongSwan distribution. Many thanks go to Stephan Scholz from astaro | |
3224 | for his integration work. ipsec starter is a C program which is going | |
3225 | to replace the various shell and awk starter scripts (setup, _plutoload, | |
3226 | _plutostart, _realsetup, _startklips, _confread, and auto). Since | |
3227 | ipsec.conf is now parsed only once, the starting of multiple tunnels is | |
b3ab7a48 | 3228 | accelerated tremendously. |
997358a6 MW |
3229 | |
3230 | - Added support of %defaultroute to the ipsec starter. If the IP address | |
b6b90b68 | 3231 | changes, a HUP signal to the ipsec starter will automatically |
997358a6 MW |
3232 | reload pluto's connections. |
3233 | ||
3234 | - moved most compile time configurations from pluto/Makefile to | |
3235 | Makefile.inc by defining the options USE_LIBCURL, USE_LDAP, | |
3236 | USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE. | |
3237 | ||
3238 | - removed the ipsec verify and ipsec newhostkey commands | |
3239 | ||
3240 | - fixed some 64-bit issues in formatted print statements | |
3241 | ||
3242 | - The scepclient functionality implementing the Simple Certificate | |
3243 | Enrollment Protocol (SCEP) is nearly complete but hasn't been | |
3244 | documented yet. | |
3245 | ||
3246 | ||
3247 | strongswan-2.5.7 | |
3248 | ---------------- | |
3249 | ||
2db6d5b8 | 3250 | - CA certificates are now automatically loaded from a smartcard |
997358a6 MW |
3251 | or USB crypto token and appear in the ipsec auto --listcacerts |
3252 | listing. | |
3253 | ||
3254 | ||
3255 | strongswan-2.5.6 | |
3256 | ---------------- | |
3257 | ||
3258 | - when using "ipsec whack --scencrypt <data>" with a PKCS#11 | |
3259 | library that does not support the C_Encrypt() Cryptoki | |
3260 | function (e.g. OpenSC), the RSA encryption is done in | |
3261 | software using the public key fetched from the smartcard. | |
3262 | ||
b6b90b68 | 3263 | - The scepclient function now allows to define the |
997358a6 MW |
3264 | validity of a self-signed certificate using the --days, |
3265 | --startdate, and --enddate options. The default validity | |
3266 | has been changed from one year to five years. | |
3267 | ||
3268 | ||
3269 | strongswan-2.5.5 | |
3270 | ---------------- | |
3271 | ||
3272 | - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11 | |
3273 | interface to other applications for RSA encryption and decryption | |
3274 | via the whack interface. Notation: | |
3275 | ||
3276 | ipsec whack --scencrypt <data> | |
3277 | [--inbase 16|hex|64|base64|256|text|ascii] | |
3278 | [--outbase 16|hex|64|base64|256|text|ascii] | |
3279 | [--keyid <keyid>] | |
3280 | ||
3281 | ipsec whack --scdecrypt <data> | |
3282 | [--inbase 16|hex|64|base64|256|text|ascii] | |
3283 | [--outbase 16|hex|64|base64|256|text|ascii] | |
3284 | [--keyid <keyid>] | |
3285 | ||
b6b90b68 | 3286 | The default setting for inbase and outbase is hex. |
997358a6 MW |
3287 | |
3288 | The new proxy interface can be used for securing symmetric | |
3289 | encryption keys required by the cryptoloop or dm-crypt | |
3290 | disk encryption schemes, especially in the case when | |
3291 | pkcs11keepstate=yes causes pluto to lock the pkcs11 slot | |
3292 | permanently. | |
3293 | ||
3294 | - if the file /etc/ipsec.secrets is lacking during the startup of | |
3295 | pluto then the root-readable file /etc/ipsec.d/private/myKey.der | |
3296 | containing a 2048 bit RSA private key and a matching self-signed | |
3297 | certificate stored in the file /etc/ipsec.d/certs/selfCert.der | |
3298 | is automatically generated by calling the function | |
3299 | ||
3300 | ipsec scepclient --out pkcs1 --out cert-self | |
3301 | ||
3302 | scepclient was written by Jan Hutter and Martin Willi, students | |
3303 | at the University of Applied Sciences in Rapperswil, Switzerland. | |
3304 | ||
3305 | ||
3306 | strongswan-2.5.4 | |
3307 | ---------------- | |
3308 | ||
3309 | - the current extension of the PKCS#7 framework introduced | |
3310 | a parsing error in PKCS#7 wrapped X.509 certificates that are | |
3311 | e.g. transmitted by Windows XP when multi-level CAs are used. | |
3312 | the parsing syntax has been fixed. | |
3313 | ||
3314 | - added a patch by Gerald Richter which tolerates multiple occurrences | |
3315 | of the ipsec0 interface when using KLIPS. | |
3316 | ||
3317 | ||
3318 | strongswan-2.5.3 | |
3319 | ---------------- | |
3320 | ||
3321 | - with gawk-3.1.4 the word "default2 has become a protected | |
3322 | keyword for use in switch statements and cannot be used any | |
3323 | more in the strongSwan scripts. This problem has been | |
3324 | solved by renaming "default" to "defaults" and "setdefault" | |
3325 | in the scripts _confread and auto, respectively. | |
3326 | ||
3327 | - introduced the parameter leftsendcert with the values | |
3328 | ||
3329 | always|yes (the default, always send a cert) | |
3330 | ifasked (send the cert only upon a cert request) | |
3331 | never|no (never send a cert, used for raw RSA keys and | |
b6b90b68 | 3332 | self-signed certs) |
997358a6 MW |
3333 | |
3334 | - fixed the initialization of the ESP key length to a default of | |
3335 | 128 bits in the case that the peer does not send a key length | |
53f8ac3d | 3336 | attribute for AES encryption. |
997358a6 MW |
3337 | |
3338 | - applied Herbert Xu's uniqueIDs patch | |
3339 | ||
3340 | - applied Herbert Xu's CLOEXEC patches | |
3341 | ||
3342 | ||
3343 | strongswan-2.5.2 | |
3344 | ---------------- | |
3345 | ||
3346 | - CRLs can now be cached also in the case when the issuer's | |
3347 | certificate does not contain a subjectKeyIdentifier field. | |
3348 | In that case the subjectKeyIdentifier is computed by pluto as the | |
3349 | 160 bit SHA-1 hash of the issuer's public key in compliance | |
3350 | with section 4.2.1.2 of RFC 3280. | |
3351 | ||
3352 | - Fixed a bug introduced by strongswan-2.5.1 which eliminated | |
3353 | not only multiple Quick Modes of a given connection but also | |
3354 | multiple connections between two security gateways. | |
3355 | ||
3356 | ||
3357 | strongswan-2.5.1 | |
3358 | ---------------- | |
3359 | ||
3360 | - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute | |
3361 | installed either by setting auto=route in ipsec.conf or by | |
b3ab7a48 | 3362 | a connection put into hold, generates an XFRM_ACQUIRE event |
2db6d5b8 | 3363 | for each packet that wants to use the not-yet existing |
b3ab7a48 | 3364 | tunnel. Up to now each XFRM_ACQUIRE event led to an entry in |
997358a6 MW |
3365 | the Quick Mode queue, causing multiple IPsec SA to be |
3366 | established in rapid succession. Starting with strongswan-2.5.1 | |
3367 | only a single IPsec SA is established per host-pair connection. | |
3368 | ||
3369 | - Right after loading the PKCS#11 module, all smartcard slots are | |
3370 | searched for certificates. The result can be viewed using | |
3371 | the command | |
3372 | ||
3373 | ipsec auto --listcards | |
3374 | ||
3375 | The certificate objects found in the slots are numbered | |
3376 | starting with #1, #2, etc. This position number can be used to address | |
3377 | certificates (leftcert=%smartcard) and keys (: PIN %smartcard) | |
3378 | in ipsec.conf and ipsec.secrets, respectively: | |
3379 | ||
3380 | %smartcard (selects object #1) | |
3381 | %smartcard#1 (selects object #1) | |
3382 | %smartcard#3 (selects object #3) | |
3383 | ||
3384 | As an alternative the existing retrieval scheme can be used: | |
3385 | ||
3386 | %smartcard:45 (selects object with id=45) | |
3387 | %smartcard0 (selects first object in slot 0) | |
3388 | %smartcard4:45 (selects object in slot 4 with id=45) | |
3389 | ||
3390 | - Depending on the settings of CKA_SIGN and CKA_DECRYPT | |
3391 | private key flags either C_Sign() or C_Decrypt() is used | |
3392 | to generate a signature. | |
3393 | ||
3394 | - The output buffer length parameter siglen in C_Sign() | |
3395 | is now initialized to the actual size of the output | |
3396 | buffer prior to the function call. This fixes the | |
3397 | CKR_BUFFER_TOO_SMALL error that could occur when using | |
3398 | the OpenSC PKCS#11 module. | |
3399 | ||
3400 | - Changed the initialization of the PKCS#11 CK_MECHANISM in | |
3401 | C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }. | |
3402 | ||
3403 | - Refactored the RSA public/private key code and transferred it | |
3404 | from keys.c to the new pkcs1.c file as a preparatory step | |
3405 | towards the release of the SCEP client. | |
3406 | ||
3407 | ||
3408 | strongswan-2.5.0 | |
3409 | ---------------- | |
3410 | ||
3411 | - The loading of a PKCS#11 smartcard library module during | |
3412 | runtime does not require OpenSC library functions any more | |
3413 | because the corresponding code has been integrated into | |
3414 | smartcard.c. Also the RSAREF pkcs11 header files have been | |
3415 | included in a newly created pluto/rsaref directory so that | |
3416 | no external include path has to be defined any longer. | |
3417 | ||
3418 | - A long-awaited feature has been implemented at last: | |
3419 | The local caching of CRLs fetched via HTTP or LDAP, activated | |
3420 | by the parameter cachecrls=yes in the config setup section | |
3421 | of ipsec.conf. The dynamically fetched CRLs are stored under | |
3422 | a unique file name containing the issuer's subjectKeyID | |
3423 | in /etc/ipsec.d/crls. | |
b6b90b68 | 3424 | |
997358a6 MW |
3425 | - Applied a one-line patch courtesy of Michael Richardson |
3426 | from the Openswan project which fixes the kernel-oops | |
3427 | in KLIPS when an snmp daemon is running on the same box. | |
3428 | ||
3429 | ||
3430 | strongswan-2.4.4 | |
3431 | ---------------- | |
3432 | ||
3433 | - Eliminated null length CRL distribution point strings. | |
3434 | ||
3435 | - Fixed a trust path evaluation bug introduced with 2.4.3 | |
3436 | ||
3437 | ||
3438 | strongswan-2.4.3 | |
3439 | ---------------- | |
3440 | ||
3441 | - Improved the joint OCSP / CRL revocation policy. | |
3442 | OCSP responses have precedence over CRL entries. | |
3443 | ||
3444 | - Introduced support of CRLv2 reason codes. | |
3445 | ||
3446 | - Fixed a bug with key-pad equipped readers which caused | |
3447 | pluto to prompt for the pin via the console when the first | |
3448 | occasion to enter the pin via the key-pad was missed. | |
3449 | ||
3450 | - When pluto is built with LDAP_V3 enabled, the library | |
3451 | liblber required by newer versions of openldap is now | |
3452 | included. | |
3453 | ||
3454 | ||
3455 | strongswan-2.4.2 | |
3456 | ---------------- | |
3457 | ||
3458 | - Added the _updown_espmark template which requires all | |
3459 | incoming ESP traffic to be marked with a default mark | |
3460 | value of 50. | |
b6b90b68 | 3461 | |
997358a6 MW |
3462 | - Introduced the pkcs11keepstate parameter in the config setup |
3463 | section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11 | |
b6b90b68 | 3464 | session and login states are kept as long as possible during |
997358a6 MW |
3465 | the lifetime of pluto. This means that a PIN entry via a key |
3466 | pad has to be done only once. | |
3467 | ||
3468 | - Introduced the pkcs11module parameter in the config setup | |
3469 | section of ipsec.conf which specifies the PKCS#11 module | |
3470 | to be used with smart cards. Example: | |
b6b90b68 | 3471 | |
997358a6 | 3472 | pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo |
b6b90b68 | 3473 | |
997358a6 MW |
3474 | - Added support of smartcard readers equipped with a PIN pad. |
3475 | ||
3476 | - Added patch by Jay Pfeifer which detects when netkey | |
3477 | modules have been statically built into the Linux 2.6 kernel. | |
3478 | ||
3479 | - Added two patches by Herbert Xu. The first uses ip xfrm | |
3480 | instead of setkey to flush the IPsec policy database. The | |
3481 | second sets the optional flag in inbound IPComp SAs only. | |
b6b90b68 | 3482 | |
997358a6 MW |
3483 | - Applied Ulrich Weber's patch which fixes an interoperability |
3484 | problem between native IPsec and KLIPS systems caused by | |
3485 | setting the replay window to 32 instead of 0 for ipcomp. | |
3486 | ||
3487 | ||
3488 | strongswan-2.4.1 | |
3489 | ---------------- | |
3490 | ||
3491 | - Fixed a bug which caused an unwanted Mode Config request | |
3492 | to be initiated in the case where "right" was used to denote | |
3493 | the local side in ipsec.conf and "left" the remote side, | |
3494 | contrary to the recommendation that "right" be remote and | |
3495 | "left" be"local". | |
3496 | ||
3497 | ||
3498 | strongswan-2.4.0a | |
3499 | ----------------- | |
3500 | ||
3501 | - updated Vendor ID to strongSwan-2.4.0 | |
3502 | ||
3503 | - updated copyright statement to include David Buechi and | |
3504 | Michael Meier | |
b6b90b68 MW |
3505 | |
3506 | ||
997358a6 MW |
3507 | strongswan-2.4.0 |
3508 | ---------------- | |
3509 | ||
3510 | - strongSwan now communicates with attached smartcards and | |
3511 | USB crypto tokens via the standardized PKCS #11 interface. | |
3512 | By default the OpenSC library from www.opensc.org is used | |
3513 | but any other PKCS#11 library could be dynamically linked. | |
3514 | strongSwan's PKCS#11 API was implemented by David Buechi | |
3515 | and Michael Meier, both graduates of the Zurich University | |
3516 | of Applied Sciences in Winterthur, Switzerland. | |
3517 | ||
3518 | - When a %trap eroute is triggered by an outgoing IP packet | |
3519 | then the native IPsec stack of the Linux 2.6 kernel [often/ | |
3520 | always?] returns an XFRM_ACQUIRE message with an undefined | |
3521 | protocol family field and the connection setup fails. | |
3522 | As a workaround IPv4 (AF_INET) is now assumed. | |
b6b90b68 MW |
3523 | |
3524 | - the results of the UML test scenarios are now enhanced | |
997358a6 | 3525 | with block diagrams of the virtual network topology used |
b6b90b68 | 3526 | in a particular test. |
997358a6 MW |
3527 | |
3528 | ||
3529 | strongswan-2.3.2 | |
3530 | ---------------- | |
3531 | ||
3532 | - fixed IV used to decrypt informational messages. | |
3533 | This bug was introduced with Mode Config functionality. | |
b6b90b68 | 3534 | |
997358a6 MW |
3535 | - fixed NCP Vendor ID. |
3536 | ||
3537 | - undid one of Ulrich Weber's maximum udp size patches | |
3538 | because it caused a segmentation fault with NAT-ed | |
3539 | Delete SA messages. | |
b6b90b68 | 3540 | |
997358a6 MW |
3541 | - added UML scenarios wildcards and attr-cert which |
3542 | demonstrate the implementation of IPsec policies based | |
3543 | on wildcard parameters contained in Distinguished Names and | |
3544 | on X.509 attribute certificates, respectively. | |
3545 | ||
3546 | ||
3547 | strongswan-2.3.1 | |
3548 | ---------------- | |
3549 | ||
3550 | - Added basic Mode Config functionality | |
3551 | ||
3552 | - Added Mathieu Lafon's patch which upgrades the status of | |
3553 | the NAT-Traversal implementation to RFC 3947. | |
b6b90b68 | 3554 | |
997358a6 MW |
3555 | - The _startklips script now also loads the xfrm4_tunnel |
3556 | module. | |
b6b90b68 | 3557 | |
997358a6 MW |
3558 | - Added Ulrich Weber's netlink replay window size and |
3559 | maximum udp size patches. | |
3560 | ||
3561 | - UML testing now uses the Linux 2.6.10 UML kernel by default. | |
b6b90b68 | 3562 | |
997358a6 MW |
3563 | |
3564 | strongswan-2.3.0 | |
3565 | ---------------- | |
3566 | ||
3567 | - Eric Marchionni and Patrik Rayo, both recent graduates from | |
3568 | the Zuercher Hochschule Winterthur in Switzerland, created a | |
3569 | User-Mode-Linux test setup for strongSwan. For more details | |
3570 | please read the INSTALL and README documents in the testing | |
3571 | subdirectory. | |
3572 | ||
3573 | - Full support of group attributes based on X.509 attribute | |
b6b90b68 | 3574 | certificates. Attribute certificates can be generated |
997358a6 | 3575 | using the openac facility. For more details see |
b6b90b68 | 3576 | |
997358a6 | 3577 | man ipsec_openac. |
b6b90b68 | 3578 | |
997358a6 MW |
3579 | The group attributes can be used in connection definitions |
3580 | in order to give IPsec access to specific user groups. | |
3581 | This is done with the new parameter left|rightgroups as in | |
b6b90b68 | 3582 | |
997358a6 MW |
3583 | rightgroups="Research, Sales" |
3584 | ||
3585 | giving access to users possessing the group attributes | |
3586 | Research or Sales, only. | |
3587 | ||
3588 | - In Quick Mode clients with subnet mask /32 are now | |
b6b90b68 | 3589 | coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should |
997358a6 MW |
3590 | fix rekeying problems with the SafeNet/SoftRemote and NCP |
3591 | Secure Entry Clients. | |
3592 | ||
3593 | - Changed the defaults of the ikelifetime and keylife parameters | |
3594 | to 3h and 1h, respectively. The maximum allowable values are | |
3595 | now both set to 24 h. | |
3596 | ||
3597 | - Suppressed notification wars between two IPsec peers that | |
3598 | could e.g. be triggered by incorrect ISAKMP encryption. | |
3599 | ||
3600 | - Public RSA keys can now have identical IDs if either the | |
3601 | issuing CA or the serial number is different. The serial | |
3602 | number of a certificate is now shown by the command | |
b6b90b68 | 3603 | |
997358a6 MW |
3604 | ipsec auto --listpubkeys |
3605 | ||
3606 | ||
3607 | strongswan-2.2.2 | |
3608 | ---------------- | |
3609 | ||
3610 | - Added Tuomo Soini's sourceip feature which allows a strongSwan | |
3611 | roadwarrior to use a fixed Virtual IP (see README section 2.6) | |
3612 | and reduces the well-known four tunnel case on VPN gateways to | |
3613 | a single tunnel definition (see README section 2.4). | |
3614 | ||
f3bb1bd0 | 3615 | - Fixed a bug occurring with NAT-Traversal enabled when the responder |
997358a6 MW |
3616 | suddenly turns initiator and the initiator cannot find a matching |
3617 | connection because of the floated IKE port 4500. | |
b6b90b68 | 3618 | |
997358a6 MW |
3619 | - Removed misleading ipsec verify command from barf. |
3620 | ||
3621 | - Running under the native IP stack, ipsec --version now shows | |
3622 | the Linux kernel version (courtesy to the Openswan project). | |
3623 | ||
3624 | ||
3625 | strongswan-2.2.1 | |
3626 | ---------------- | |
3627 | ||
3628 | - Introduced the ipsec auto --listalgs monitoring command which lists | |
3629 | all currently registered IKE and ESP algorithms. | |
3630 | ||
f3bb1bd0 | 3631 | - Fixed a bug in the ESP algorithm selection occurring when the strict flag |
997358a6 | 3632 | is set and the first proposed transform does not match. |
b6b90b68 | 3633 | |
997358a6 | 3634 | - Fixed another deadlock in the use of the lock_certs_and_keys() mutex, |
f3bb1bd0 | 3635 | occurring when a smartcard is present. |
997358a6 MW |
3636 | |
3637 | - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event. | |
b6b90b68 | 3638 | |
997358a6 MW |
3639 | - Fixed the printing of the notification names (null) |
3640 | ||
3641 | - Applied another of Herbert Xu's Netlink patches. | |
3642 | ||
3643 | ||
3644 | strongswan-2.2.0 | |
3645 | ---------------- | |
3646 | ||
3647 | - Support of Dead Peer Detection. The connection parameter | |
3648 | ||
3649 | dpdaction=clear|hold | |
b6b90b68 | 3650 | |
997358a6 MW |
3651 | activates DPD for the given connection. |
3652 | ||
3653 | - The default Opportunistic Encryption (OE) policy groups are not | |
3654 | automatically included anymore. Those wishing to activate OE can include | |
3655 | the policy group with the following statement in ipsec.conf: | |
b6b90b68 | 3656 | |
997358a6 | 3657 | include /etc/ipsec.d/examples/oe.conf |
b6b90b68 | 3658 | |
997358a6 MW |
3659 | The default for [right|left]rsasigkey is now set to %cert. |
3660 | ||
3661 | - strongSwan now has a Vendor ID of its own which can be activated | |
3662 | using the compile option VENDORID | |
3663 | ||
3664 | - Applied Herbert Xu's patch which sets the compression algorithm correctly. | |
3665 | ||
3666 | - Applied Herbert Xu's patch fixing an ESPINUDP problem | |
3667 | ||
3668 | - Applied Herbert Xu's patch setting source/destination port numbers. | |
3669 | ||
3670 | - Reapplied one of Herbert Xu's NAT-Traversal patches which got | |
3671 | lost during the migration from SuperFreeS/WAN. | |
b6b90b68 | 3672 | |
997358a6 MW |
3673 | - Fixed a deadlock in the use of the lock_certs_and_keys() mutex. |
3674 | ||
3675 | - Fixed the unsharing of alg parameters when instantiating group | |
3676 | connection. | |
b6b90b68 | 3677 | |
997358a6 MW |
3678 | |
3679 | strongswan-2.1.5 | |
3680 | ---------------- | |
3681 | ||
3682 | - Thomas Walpuski made me aware of a potential DoS attack via | |
3683 | a PKCS#7-wrapped certificate bundle which could overwrite valid CA | |
3684 | certificates in Pluto's authority certificate store. This vulnerability | |
3685 | was fixed by establishing trust in CA candidate certificates up to a | |
3686 | trusted root CA prior to insertion into Pluto's chained list. | |
3687 | ||
3688 | - replaced the --assign option by the -v option in the auto awk script | |
3689 | in order to make it run with mawk under debian/woody. | |
3690 | ||
3691 | ||
3692 | strongswan-2.1.4 | |
3693 | ---------------- | |
3694 | ||
3695 | - Split of the status information between ipsec auto --status (concise) | |
3696 | and ipsec auto --statusall (verbose). Both commands can be used with | |
3697 | an optional connection selector: | |
3698 | ||
3699 | ipsec auto --status[all] <connection_name> | |
3700 | ||
3701 | - Added the description of X.509 related features to the ipsec_auto(8) | |
3702 | man page. | |
3703 | ||
3704 | - Hardened the ASN.1 parser in debug mode, especially the printing | |
3705 | of malformed distinguished names. | |
3706 | ||
3707 | - The size of an RSA public key received in a certificate is now restricted to | |
3708 | ||
3709 | 512 bits <= modulus length <= 8192 bits. | |
3710 | ||
3711 | - Fixed the debug mode enumeration. | |
3712 | ||
3713 | ||
3714 | strongswan-2.1.3 | |
3715 | ---------------- | |
3716 | ||
3717 | - Fixed another PKCS#7 vulnerability which could lead to an | |
3718 | endless loop while following the X.509 trust chain. | |
b6b90b68 | 3719 | |
997358a6 MW |
3720 | |
3721 | strongswan-2.1.2 | |
3722 | ---------------- | |
3723 | ||
3724 | - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski | |
3725 | that accepted end certificates having identical issuer and subject | |
3726 | distinguished names in a multi-tier X.509 trust chain. | |
b6b90b68 | 3727 | |
997358a6 MW |
3728 | |
3729 | strongswan-2.1.1 | |
3730 | ---------------- | |
3731 | ||
3732 | - Removed all remaining references to ipsec_netlink.h in KLIPS. | |
3733 | ||
3734 | ||
3735 | strongswan-2.1.0 | |
3736 | ---------------- | |
3737 | ||
3738 | - The new "ca" section allows to define the following parameters: | |
3739 | ||
3740 | ca kool | |
53f8ac3d TB |
3741 | cacert=koolCA.pem # cacert of kool CA |
3742 | ocspuri=http://ocsp.kool.net:8001 # ocsp server | |
3743 | ldapserver=ldap.kool.net # default ldap server | |
3744 | crluri=http://www.kool.net/kool.crl # crl distribution point | |
3745 | crluri2="ldap:///O=Kool, C= .." # crl distribution point #2 | |
3746 | auto=add # add, ignore | |
b6b90b68 | 3747 | |
997358a6 | 3748 | The ca definitions can be monitored via the command |
b6b90b68 | 3749 | |
53f8ac3d | 3750 | ipsec auto --listcainfos |
997358a6 MW |
3751 | |
3752 | - Fixed cosmetic corruption of /proc filesystem by integrating | |
3753 | D. Hugh Redelmeier's freeswan-2.06 kernel fixes. | |
3754 | ||
3755 | ||
3756 | strongswan-2.0.2 | |
3757 | ---------------- | |
3758 | ||
3759 | - Added support for the 818043 NAT-Traversal update of Microsoft's | |
3760 | Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode. | |

3765 | - Fixed a couple of 64 bit issues (mostly casts to int). |
3766 | Thanks to Ken Bantoft who checked my sources on a 64 bit platform. | |

3768 | - Replaced s[n]printf() statements in the kernel by ipsec_snprintf(). | |
3769 | Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro | |

3774 | ---------------- | |

3776 | - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName | |
3777 | certificate extension which contains no generalName item) can cause | |
3778 | a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has | |
3779 | been hardened to make it more robust against malformed ASN.1 objects. | |
3780 | ||
3781 | - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native | |
3782 | Linux 2.6 IPsec stack. | |
