1 | strongswan-4.1.6 | |
2 | ---------------- | |
3 | ||
4 | - the --enable-integrity-test configure option tests the | |
5 | integrity of the libstrongswan crypto code during the charon | |
6 | startup. | |
7 | ||
8 | - ipsec stroke now supports the rereadsecrets, rereadaacerts, | |
9 | rereadacerts, and listacerts options. | |
10 | ||
11 | ||
12 | strongswan-4.1.5 | |
13 | ---------------- | |
14 | ||
15 | - If a DNS lookup failure occurs when resolving right=%<FQDN> | |
16 | or right=<FQDN> combined with rightallowany=yes then the | |
17 | connection is not updated by ipsec starter thus preventing | |
18 | the disruption of an active IPsec connection. Only if the DNS | |
19 | lookup successfully returns with a changed IP address the | |
20 | corresponding connection definition is updated. | |
21 | ||
22 | - Routes installed by the keying daemons are now in a separate | |
23 | routing table with the ID 100 to avoid conflicts with the main | |
24 | table. Route lookup for IKEv2 traffic is done in userspace to ignore | |
25 | routes installed for IPsec, as IKE traffic shouldn't get encapsulated. | |
26 | ||
27 | ||
28 | strongswan-4.1.4 | |
29 | ---------------- | |
30 | ||
31 | - The pluto IKEv1 daemon now exhibits the same behaviour as its | |
32 | IKEv2 companion charon by inserting an explicit route via the | |
33 | _updown script only if a sourceip exists. This is admissible | |
34 | since routing through the IPsec tunnel is handled automatically | |
35 | by NETKEY's IPsec policies. As a consequence the left|rightnexthop | |
36 | parameter is not required any more. | |
37 | ||
38 | - The new IKEv1 parameter right|leftallowany parameters helps to handle | |
39 | the case where both peers possess dynamic IP addresses that are | |
40 | usually resolved using DynDNS or a similar service. The configuration | |
41 | ||
42 | right=peer.foo.bar | |
43 | rightallowany=yes | |
44 | ||
45 | can be used by the initiator to start up a connection to a peer | |
46 | by resolving peer.foo.bar into the currently allocated IP address. | |
47 | Thanks to the rightallowany flag the connection behaves later on | |
48 | as | |
49 | ||
50 | right=%any | |
51 | ||
52 | so that the peer can rekey the connection as an initiator when his | |
53 | IP address changes. An alternative notation is | |
54 | ||
55 | right=%peer.foo.bar | |
56 | ||
57 | which will implicitly set rightallowany=yes. | |
58 | ||
59 | - ipsec starter now fails more gracefully in the presence of parsing | |
60 | errors. Flawed ca and conn section are discarded and pluto is started | |
61 | if non-fatal errors only were encountered. If right=%peer.foo.bar | |
62 | cannot be resolved by DNS then right=%any will be used so that passive | |
63 | connections as a responder are still possible. | |
64 | ||
65 | - The new pkcs11initargs parameter that can be placed in the | |
66 | setup config section of /etc/ipsec.conf allows the definition | |
67 | of an argument string that is used with the PKCS#11 C_Initialize() | |
68 | function. This non-standard feature is required by the NSS softoken | |
69 | library. This patch was contributed by Robert Varga. | |
70 | ||
71 | - Fixed a bug in ipsec starter introduced by strongswan-2.8.5 | |
72 | which caused a segmentation fault in the presence of unknown | |
73 | or misspelt keywords in ipsec.conf. This bug fix was contributed | |
74 | by Robert Varga. | |
75 | ||
76 | - Partial support for MOBIKE in IKEv2. The initiator acts on interface/ | |
77 | address configuration changes and updates IKE and IPsec SAs dynamically. | |
78 | ||
79 | ||
80 | strongswan-4.1.3 | |
81 | ---------------- | |
82 | ||
83 | - IKEv2 peer configuration selection now can be based on a given | |
84 | certification authority using the rightca= statement. | |
85 | ||
86 | - IKEv2 authentication based on RSA signatures now can handle multiple | |
87 | certificates issued for a given peer ID. This allows a smooth transition | |
88 | in the case of a peer certificate renewal. | |
89 | ||
90 | - IKEv2: Support for requesting a specific virtual IP using leftsourceip on the | |
91 | client and returning requested virtual IPs using rightsourceip=%config | |
92 | on the server. If the server does not support configuration payloads, the | |
93 | client enforces its leftsourceip parameter. | |
94 | ||
95 | - The ./configure options --with-uid/--with-gid allow pluto and charon | |
96 | to drop their privileges to a minimum and change to an other UID/GID. This | |
97 | improves the systems security, as a possible intruder may only get the | |
98 | CAP_NET_ADMIN capability. | |
99 | ||
100 | - Further modularization of charon: Pluggable control interface and | |
101 | configuration backend modules provide extensibility. The control interface | |
102 | for stroke is included, and further interfaces using DBUS (NetworkManager) | |
103 | or XML are on the way. A backend for storing configurations in the daemon | |
104 | is provided and more advanced backends (using e.g. a database) are trivial | |
105 | to implement. | |
106 | ||
107 | - Fixed a compilation failure in libfreeswan occuring with Linux kernel | |
108 | headers > 2.6.17. | |
109 | ||
110 | ||
111 | strongswan-4.1.2 | |
112 | ---------------- | |
113 | ||
114 | - Support for an additional Diffie-Hellman exchange when creating/rekeying | |
115 | a CHILD_SA in IKEv2 (PFS). PFS is enabled when the proposal contains a | |
116 | DH group (e.g. "esp=aes128-sha1-modp1536"). Further, DH group negotiation | |
117 | is implemented properly for rekeying. | |
118 | ||
119 | - Support for the AES-XCBC-96 MAC algorithm for IPsec SAs when using IKEv2 | |
120 | (requires linux >= 2.6.20). It is enabled using e.g. "esp=aes256-aesxcbc". | |
121 | ||
122 | - Working IPv4-in-IPv6 and IPv6-in-IPv4 tunnels for linux >= 2.6.21. | |
123 | ||
124 | - Added support for EAP modules which do not establish an MSK. | |
125 | ||
126 | - Removed the dependencies from the /usr/include/linux/ headers by | |
127 | including xfrm.h, ipsec.h, and pfkeyv2.h in the distribution. | |
128 | ||
129 | - crlNumber is now listed by ipsec listcrls | |
130 | ||
131 | - The xauth_modules.verify_secret() function now passes the | |
132 | connection name. | |
133 | ||
134 | ||
135 | strongswan-4.1.1 | |
136 | ---------------- | |
137 | ||
138 | - Server side cookie support. If to may IKE_SAs are in CONNECTING state, | |
139 | cookies are enabled and protect against DoS attacks with faked source | |
140 | addresses. Number of IKE_SAs in CONNECTING state is also limited per | |
141 | peer address to avoid resource exhaustion. IKE_SA_INIT messages are | |
142 | compared to properly detect retransmissions and incoming retransmits are | |
143 | detected even if the IKE_SA is blocked (e.g. doing OCSP fetches). | |
144 | ||
145 | - The IKEv2 daemon charon now supports dynamic http- and ldap-based CRL | |
146 | fetching enabled by crlcheckinterval > 0 and caching fetched CRLs | |
147 | enabled by cachecrls=yes. | |
148 | ||
149 | - Added the configuration options --enable-nat-transport which enables | |
150 | the potentially insecure NAT traversal for IPsec transport mode and | |
151 | --disable-vendor-id which disables the sending of the strongSwan | |
152 | vendor ID. | |
153 | ||
154 | - Fixed a long-standing bug in the pluto IKEv1 daemon which caused | |
155 | a segmentation fault if a malformed payload was detected in the | |
156 | IKE MR2 message and pluto tried to send an encrypted notification | |
157 | message. | |
158 | ||
159 | - Added the NATT_IETF_02_N Vendor ID in order to support IKEv1 connections | |
160 | with Windows 2003 Server which uses a wrong VID hash. | |
161 | ||
162 | ||
163 | strongswan-4.1.0 | |
164 | ---------------- | |
165 | ||
166 | - Support of SHA2_384 hash function for protecting IKEv1 | |
167 | negotiations and support of SHA2 signatures in X.509 certificates. | |
168 | ||
169 | - Fixed a serious bug in the computation of the SHA2-512 HMAC | |
170 | function. Introduced automatic self-test of all IKEv1 hash | |
171 | and hmac functions during pluto startup. Failure of a self-test | |
172 | currently issues a warning only but does not exit pluto [yet]. | |
173 | ||
174 | - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2. | |
175 | ||
176 | - Full support of CA information sections. ipsec listcainfos | |
177 | now shows all collected crlDistributionPoints and OCSP | |
178 | accessLocations. | |
179 | ||
180 | - Support of the Online Certificate Status Protocol (OCSP) for IKEv2. | |
181 | This feature requires the HTTP fetching capabilities of the libcurl | |
182 | library which must be enabled by setting the --enable-http configure | |
183 | option. | |
184 | ||
185 | - Refactored core of the IKEv2 message processing code, allowing better | |
186 | code reuse and separation. | |
187 | ||
188 | - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration | |
189 | payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted | |
190 | by the requestor and installed in a resolv.conf file. | |
191 | ||
192 | - The IKEv2 daemon charon installs a route for each IPsec policy to use | |
193 | the correct source address even if an application does not explicitly | |
194 | specify it. | |
195 | ||
196 | - Integrated the EAP framework into charon which loads pluggable EAP library | |
197 | modules. The ipsec.conf parameter authby=eap initiates EAP authentication | |
198 | on the client side, while the "eap" parameter on the server side defines | |
199 | the EAP method to use for client authentication. | |
200 | A generic client side EAP-Identity module and an EAP-SIM authentication | |
201 | module using a third party card reader implementation are included. | |
202 | ||
203 | - Added client side support for cookies. | |
204 | ||
205 | - Integrated the fixes done at the IKEv2 interoperability bakeoff, including | |
206 | strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor | |
207 | fixes to enhance interoperability with other implementations. | |
208 | ||
209 | ||
210 | strongswan-4.0.7 | |
211 | ---------------- | |
212 | ||
213 | - strongSwan now interoperates with the NCP Secure Entry Client, | |
214 | the Shrew Soft VPN Client, and the Cisco VPN client, doing both | |
215 | XAUTH and Mode Config. | |
216 | ||
217 | - UNITY attributes are now recognized and UNITY_BANNER is set | |
218 | to a default string. | |
219 | ||
220 | ||
221 | strongswan-4.0.6 | |
222 | ---------------- | |
223 | ||
224 | - IKEv1: Support for extended authentication (XAUTH) in combination | |
225 | with ISAKMP Main Mode RSA or PSK authentication. Both client and | |
226 | server side were implemented. Handling of user credentials can | |
227 | be done by a run-time loadable XAUTH module. By default user | |
228 | credentials are stored in ipsec.secrets. | |
229 | ||
230 | - IKEv2: Support for reauthentication when rekeying | |
231 | ||
232 | - IKEv2: Support for transport mode | |
233 | ||
234 | - fixed a lot of bugs related to byte order | |
235 | ||
236 | - various other bugfixes | |
237 | ||
238 | ||
239 | strongswan-4.0.5 | |
240 | ---------------- | |
241 | ||
242 | - IKEv1: Implementation of ModeConfig push mode via the new connection | |
243 | keyword modeconfig=push allows interoperability with Cisco VPN gateways. | |
244 | ||
245 | - IKEv1: The command ipsec statusall now shows "DPD active" for all | |
246 | ISAKMP SAs that are under active Dead Peer Detection control. | |
247 | ||
248 | - IKEv2: Charon's logging and debugging framework has been completely rewritten. | |
249 | Instead of logger, special printf() functions are used to directly | |
250 | print objects like hosts (%H) identifications (%D), certificates (%Q), | |
251 | etc. The number of debugging levels have been reduced to: | |
252 | ||
253 | 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private) | |
254 | ||
255 | The debugging levels can either be specified statically in ipsec.conf as | |
256 | ||
257 | config setup | |
258 | charondebug="lib 1, cfg 3, net 2" | |
259 | ||
260 | or changed at runtime via stroke as | |
261 | ||
262 | ipsec stroke loglevel cfg 2 | |
263 | ||
264 | ||
265 | strongswan-4.0.4 | |
266 | ---------------- | |
267 | ||
268 | - Implemented full support for IPv6-in-IPv6 tunnels. | |
269 | ||
270 | - Added configuration options for dead peer detection in IKEv2. dpd_action | |
271 | types "clear", "hold" and "restart" are supported. The dpd_timeout | |
272 | value is not used, as the normal retransmission policy applies to | |
273 | detect dead peers. The dpd_delay parameter enables sending of empty | |
274 | informational message to detect dead peers in case of inactivity. | |
275 | ||
276 | - Added support for preshared keys in IKEv2. PSK keys configured in | |
277 | ipsec.secrets are loaded. The authby parameter specifies the authentication | |
278 | method to authentificate ourself, the other peer may use PSK or RSA. | |
279 | ||
280 | - Changed retransmission policy to respect the keyingtries parameter. | |
281 | ||
282 | - Added private key decryption. PEM keys encrypted with AES-128/192/256 | |
283 | or 3DES are supported. | |
284 | ||
285 | - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to | |
286 | encrypt IKE traffic. | |
287 | ||
288 | - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates | |
289 | signed with such a hash algorithm. | |
290 | ||
291 | - Added initial support for updown scripts. The actions up-host/client and | |
292 | down-host/client are executed. The leftfirewall=yes parameter | |
293 | uses the default updown script to insert dynamic firewall rules, a custom | |
294 | updown script may be specified with the leftupdown parameter. | |
295 | ||
296 | ||
297 | strongswan-4.0.3 | |
298 | ---------------- | |
299 | ||
300 | - Added support for the auto=route ipsec.conf parameter and the | |
301 | ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and | |
302 | CHILD_SAs dynamically on demand when traffic is detected by the | |
303 | kernel. | |
304 | ||
305 | - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter. | |
306 | As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only | |
307 | new keys are generated using perfect forward secrecy. An optional flag | |
308 | which enforces reauthentication will be implemented later. | |
309 | ||
310 | - "sha" and "sha1" are now treated as synonyms in the ike= and esp= | |
311 | algorithm configuration statements. | |
312 | ||
313 | ||
314 | strongswan-4.0.2 | |
315 | ---------------- | |
316 | ||
317 | - Full X.509 certificate trust chain verification has been implemented. | |
318 | End entity certificates can be exchanged via CERT payloads. The current | |
319 | default is leftsendcert=always, since CERTREQ payloads are not supported | |
320 | yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls. | |
321 | ||
322 | - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2 | |
323 | would offer more possibilities for traffic selection, but the Linux kernel | |
324 | currently does not support it. That's why we stick with these simple | |
325 | ipsec.conf rules for now. | |
326 | ||
327 | - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no | |
328 | IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear, | |
329 | dpddelay=60s). | |
330 | ||
331 | - Initial NAT traversal support in IKEv2. Charon includes NAT detection | |
332 | notify payloads to detect NAT routers between the peers. It switches | |
333 | to port 4500, uses UDP encapsulated ESP packets, handles peer address | |
334 | changes gracefully and sends keep alive message periodically. | |
335 | ||
336 | - Reimplemented IKE_SA state machine for charon, which allows simultaneous | |
337 | rekeying, more shared code, cleaner design, proper retransmission | |
338 | and a more extensible code base. | |
339 | ||
340 | - The mixed PSK/RSA roadwarrior detection capability introduced by the | |
341 | strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal | |
342 | payloads by the responder right before any defined IKE Main Mode state had | |
343 | been established. Although any form of bad proposal syntax was being correctly | |
344 | detected by the payload parser, the subsequent error handler didn't check | |
345 | the state pointer before logging current state information, causing an | |
346 | immediate crash of the pluto keying daemon due to a NULL pointer. | |
347 | ||
348 | ||
349 | strongswan-4.0.1 | |
350 | ---------------- | |
351 | ||
352 | - Added algorithm selection to charon: New default algorithms for | |
353 | ike=aes128-sha-modp2048, as both daemons support it. The default | |
354 | for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles | |
355 | the ike/esp parameter the same way as pluto. As this syntax does | |
356 | not allow specification of a pseudo random function, the same | |
357 | algorithm as for integrity is used (currently sha/md5). Supported | |
358 | algorithms for IKE: | |
359 | Encryption: aes128, aes192, aes256 | |
360 | Integrity/PRF: md5, sha (using hmac) | |
361 | DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192 | |
362 | and for ESP: | |
363 | Encryption: aes128, aes192, aes256, 3des, blowfish128, | |
364 | blowfish192, blowfish256 | |
365 | Integrity: md5, sha1 | |
366 | More IKE encryption algorithms will come after porting libcrypto into | |
367 | libstrongswan. | |
368 | ||
369 | - initial support for rekeying CHILD_SAs using IKEv2. Currently no | |
370 | perfect forward secrecy is used. The rekeying parameters rekey, | |
371 | rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported | |
372 | when using IKEv2. WARNING: charon currently is unable to handle | |
373 | simultaneous rekeying. To avoid such a situation, use a large | |
374 | rekeyfuzz, or even better, set rekey=no on one peer. | |
375 | ||
376 | - support for host2host, net2net, host2net (roadwarrior) tunnels | |
377 | using predefined RSA certificates (see uml scenarios for | |
378 | configuration examples). | |
379 | ||
380 | - new build environment featuring autotools. Features such | |
381 | as HTTP, LDAP and smartcard support may be enabled using | |
382 | the ./configure script. Changing install directories | |
383 | is possible, too. See ./configure --help for more details. | |
384 | ||
385 | - better integration of charon with ipsec starter, which allows | |
386 | (almost) transparent operation with both daemons. charon | |
387 | handles ipsec commands up, down, status, statusall, listall, | |
388 | listcerts and allows proper load, reload and delete of connections | |
389 | via ipsec starter. | |
390 | ||
391 | ||
392 | strongswan-4.0.0 | |
393 | ---------------- | |
394 | ||
395 | - initial support of the IKEv2 protocol. Connections in | |
396 | ipsec.conf designated by keyexchange=ikev2 are negotiated | |
397 | by the new IKEv2 charon keying daemon whereas those marked | |
398 | by keyexchange=ikev1 or the default keyexchange=ike are | |
399 | handled thy the IKEv1 pluto keying daemon. Currently only | |
400 | a limited subset of functions are available with IKEv2 | |
401 | (Default AES encryption, authentication based on locally | |
402 | imported X.509 certificates, unencrypted private RSA keys | |
403 | in PKCS#1 file format, limited functionality of the ipsec | |
404 | status command). | |
405 | ||
406 | ||
407 | strongswan-2.7.0 | |
408 | ---------------- | |
409 | ||
410 | - the dynamic iptables rules from the _updown_x509 template | |
411 | for KLIPS and the _updown_policy template for NETKEY have | |
412 | been merged into the default _updown script. The existing | |
413 | left|rightfirewall keyword causes the automatic insertion | |
414 | and deletion of ACCEPT rules for tunneled traffic upon | |
415 | the successful setup and teardown of an IPsec SA, respectively. | |
416 | left|rightfirwall can be used with KLIPS under any Linux 2.4 | |
417 | kernel or with NETKEY under a Linux kernel version >= 2.6.16 | |
418 | in conjuction with iptables >= 1.3.5. For NETKEY under a Linux | |
419 | kernel version < 2.6.16 which does not support IPsec policy | |
420 | matching yet, please continue to use a copy of the _updown_espmark | |
421 | template loaded via the left|rightupdown keyword. | |
422 | ||
423 | - a new left|righthostaccess keyword has been introduced which | |
424 | can be used in conjunction with left|rightfirewall and the | |
425 | default _updown script. By default leftfirewall=yes inserts | |
426 | a bi-directional iptables FORWARD rule for a local client network | |
427 | with a netmask different from 255.255.255.255 (single host). | |
428 | This does not allow to access the VPN gateway host via its | |
429 | internal network interface which is part of the client subnet | |
430 | because an iptables INPUT and OUTPUT rule would be required. | |
431 | lefthostaccess=yes will cause this additional ACCEPT rules to | |
432 | be inserted. | |
433 | ||
434 | - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal | |
435 | payload is preparsed in order to find out whether the roadwarrior | |
436 | requests PSK or RSA so that a matching connection candidate can | |
437 | be found. | |
438 | ||
439 | ||
440 | strongswan-2.6.4 | |
441 | ---------------- | |
442 | ||
443 | - the new _updown_policy template allows ipsec policy based | |
444 | iptables firewall rules. Required are iptables version | |
445 | >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes | |
446 | the _updown_espmark template, so that no INPUT mangle rules | |
447 | are required any more. | |
448 | ||
449 | - added support of DPD restart mode | |
450 | ||
451 | - ipsec starter now allows the use of wildcards in include | |
452 | statements as e.g. in "include /etc/my_ipsec/*.conf". | |
453 | Patch courtesy of Matthias Haas. | |
454 | ||
455 | - the Netscape OID 'employeeNumber' is now recognized and can be | |
456 | used as a Relative Distinguished Name in certificates. | |
457 | ||
458 | ||
459 | strongswan-2.6.3 | |
460 | ---------------- | |
461 | ||
462 | - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec | |
463 | command and not of ipsec setup any more. | |
464 | ||
465 | - ipsec starter now supports AH authentication in conjunction with | |
466 | ESP encryption. AH authentication is configured in ipsec.conf | |
467 | via the auth=ah parameter. | |
468 | ||
469 | - The command ipsec scencrypt|scdecrypt <args> is now an alias for | |
470 | ipsec whack --scencrypt|scdecrypt <args>. | |
471 | ||
472 | - get_sa_info() now determines for the native netkey IPsec stack | |
473 | the exact time of the last use of an active eroute. This information | |
474 | is used by the Dead Peer Detection algorithm and is also displayed by | |
475 | the ipsec status command. | |
476 | ||
477 | ||
478 | strongswan-2.6.2 | |
479 | ---------------- | |
480 | ||
481 | - running under the native Linux 2.6 IPsec stack, the function | |
482 | get_sa_info() is called by ipsec auto --status to display the current | |
483 | number of transmitted bytes per IPsec SA. | |
484 | ||
485 | - get_sa_info() is also used by the Dead Peer Detection process to detect | |
486 | recent ESP activity. If ESP traffic was received from the peer within | |
487 | the last dpd_delay interval then no R_Y_THERE notification must be sent. | |
488 | ||
489 | - strongSwan now supports the Relative Distinguished Name "unstructuredName" | |
490 | in ID_DER_ASN1_DN identities. The following notations are possible: | |
491 | ||
492 | rightid="unstructuredName=John Doe" | |
493 | rightid="UN=John Doe" | |
494 | ||
495 | - fixed a long-standing bug which caused PSK-based roadwarrior connections | |
496 | to segfault in the function id.c:same_id() called by keys.c:get_secret() | |
497 | if an FQDN, USER_FQDN, or Key ID was defined, as in the following example. | |
498 | ||
499 | conn rw | |
500 | right=%any | |
501 | rightid=@foo.bar | |
502 | authby=secret | |
503 | ||
504 | - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall). | |
505 | ||
506 | - ipsec starter didn't set host_addr and client.addr ports in whack msg. | |
507 | ||
508 | - in order to guarantee backwards-compatibility with the script-based | |
509 | auto function (e.g. auto --replace), the ipsec starter scripts stores | |
510 | the defaultroute information in the temporary file /var/run/ipsec.info. | |
511 | ||
512 | - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH | |
513 | Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config | |
514 | servers. | |
515 | ||
516 | - the ipsec starter now also recognizes the parameters authby=never and | |
517 | type=passthrough|pass|drop|reject. | |
518 | ||
519 | ||
520 | strongswan-2.6.1 | |
521 | ---------------- | |
522 | ||
523 | - ipsec starter now supports the also parameter which allows | |
524 | a modular structure of the connection definitions. Thus | |
525 | "ipsec start" is now ready to replace "ipsec setup". | |
526 | ||
527 | ||
528 | strongswan-2.6.0 | |
529 | ---------------- | |
530 | ||
531 | - Mathieu Lafon's popular ipsec starter tool has been added to the | |
532 | strongSwan distribution. Many thanks go to Stephan Scholz from astaro | |
533 | for his integration work. ipsec starter is a C program which is going | |
534 | to replace the various shell and awk starter scripts (setup, _plutoload, | |
535 | _plutostart, _realsetup, _startklips, _confread, and auto). Since | |
536 | ipsec.conf is now parsed only once, the starting of multiple tunnels is | |
537 | accelerated tremedously. | |
538 | ||
539 | - Added support of %defaultroute to the ipsec starter. If the IP address | |
540 | changes, a HUP signal to the ipsec starter will automatically | |
541 | reload pluto's connections. | |
542 | ||
543 | - moved most compile time configurations from pluto/Makefile to | |
544 | Makefile.inc by defining the options USE_LIBCURL, USE_LDAP, | |
545 | USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE. | |
546 | ||
547 | - removed the ipsec verify and ipsec newhostkey commands | |
548 | ||
549 | - fixed some 64-bit issues in formatted print statements | |
550 | ||
551 | - The scepclient functionality implementing the Simple Certificate | |
552 | Enrollment Protocol (SCEP) is nearly complete but hasn't been | |
553 | documented yet. | |
554 | ||
555 | ||
556 | strongswan-2.5.7 | |
557 | ---------------- | |
558 | ||
559 | - CA certicates are now automatically loaded from a smartcard | |
560 | or USB crypto token and appear in the ipsec auto --listcacerts | |
561 | listing. | |
562 | ||
563 | ||
564 | strongswan-2.5.6 | |
565 | ---------------- | |
566 | ||
567 | - when using "ipsec whack --scencrypt <data>" with a PKCS#11 | |
568 | library that does not support the C_Encrypt() Cryptoki | |
569 | function (e.g. OpenSC), the RSA encryption is done in | |
570 | software using the public key fetched from the smartcard. | |
571 | ||
572 | - The scepclient function now allows to define the | |
573 | validity of a self-signed certificate using the --days, | |
574 | --startdate, and --enddate options. The default validity | |
575 | has been changed from one year to five years. | |
576 | ||
577 | ||
578 | strongswan-2.5.5 | |
579 | ---------------- | |
580 | ||
581 | - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11 | |
582 | interface to other applications for RSA encryption and decryption | |
583 | via the whack interface. Notation: | |
584 | ||
585 | ipsec whack --scencrypt <data> | |
586 | [--inbase 16|hex|64|base64|256|text|ascii] | |
587 | [--outbase 16|hex|64|base64|256|text|ascii] | |
588 | [--keyid <keyid>] | |
589 | ||
590 | ipsec whack --scdecrypt <data> | |
591 | [--inbase 16|hex|64|base64|256|text|ascii] | |
592 | [--outbase 16|hex|64|base64|256|text|ascii] | |
593 | [--keyid <keyid>] | |
594 | ||
595 | The default setting for inbase and outbase is hex. | |
596 | ||
597 | The new proxy interface can be used for securing symmetric | |
598 | encryption keys required by the cryptoloop or dm-crypt | |
599 | disk encryption schemes, especially in the case when | |
600 | pkcs11keepstate=yes causes pluto to lock the pkcs11 slot | |
601 | permanently. | |
602 | ||
603 | - if the file /etc/ipsec.secrets is lacking during the startup of | |
604 | pluto then the root-readable file /etc/ipsec.d/private/myKey.der | |
605 | containing a 2048 bit RSA private key and a matching self-signed | |
606 | certificate stored in the file /etc/ipsec.d/certs/selfCert.der | |
607 | is automatically generated by calling the function | |
608 | ||
609 | ipsec scepclient --out pkcs1 --out cert-self | |
610 | ||
611 | scepclient was written by Jan Hutter and Martin Willi, students | |
612 | at the University of Applied Sciences in Rapperswil, Switzerland. | |
613 | ||
614 | ||
615 | strongswan-2.5.4 | |
616 | ---------------- | |
617 | ||
618 | - the current extension of the PKCS#7 framework introduced | |
619 | a parsing error in PKCS#7 wrapped X.509 certificates that are | |
620 | e.g. transmitted by Windows XP when multi-level CAs are used. | |
621 | the parsing syntax has been fixed. | |
622 | ||
623 | - added a patch by Gerald Richter which tolerates multiple occurrences | |
624 | of the ipsec0 interface when using KLIPS. | |
625 | ||
626 | ||
627 | strongswan-2.5.3 | |
628 | ---------------- | |
629 | ||
630 | - with gawk-3.1.4 the word "default2 has become a protected | |
631 | keyword for use in switch statements and cannot be used any | |
632 | more in the strongSwan scripts. This problem has been | |
633 | solved by renaming "default" to "defaults" and "setdefault" | |
634 | in the scripts _confread and auto, respectively. | |
635 | ||
636 | - introduced the parameter leftsendcert with the values | |
637 | ||
638 | always|yes (the default, always send a cert) | |
639 | ifasked (send the cert only upon a cert request) | |
640 | never|no (never send a cert, used for raw RSA keys and | |
641 | self-signed certs) | |
642 | ||
643 | - fixed the initialization of the ESP key length to a default of | |
644 | 128 bits in the case that the peer does not send a key length | |
645 | attribute for AES encryption. | |
646 | ||
647 | - applied Herbert Xu's uniqueIDs patch | |
648 | ||
649 | - applied Herbert Xu's CLOEXEC patches | |
650 | ||
651 | ||
652 | strongswan-2.5.2 | |
653 | ---------------- | |
654 | ||
655 | - CRLs can now be cached also in the case when the issuer's | |
656 | certificate does not contain a subjectKeyIdentifier field. | |
657 | In that case the subjectKeyIdentifier is computed by pluto as the | |
658 | 160 bit SHA-1 hash of the issuer's public key in compliance | |
659 | with section 4.2.1.2 of RFC 3280. | |
660 | ||
661 | - Fixed a bug introduced by strongswan-2.5.1 which eliminated | |
662 | not only multiple Quick Modes of a given connection but also | |
663 | multiple connections between two security gateways. | |
664 | ||
665 | ||
666 | strongswan-2.5.1 | |
667 | ---------------- | |
668 | ||
669 | - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute | |
670 | installed either by setting auto=route in ipsec.conf or by | |
671 | a connection put into hold, generates an XFRM_AQUIRE event | |
672 | for each packet that wants to use the not-yet exisiting | |
673 | tunnel. Up to now each XFRM_AQUIRE event led to an entry in | |
674 | the Quick Mode queue, causing multiple IPsec SA to be | |
675 | established in rapid succession. Starting with strongswan-2.5.1 | |
676 | only a single IPsec SA is established per host-pair connection. | |
677 | ||
678 | - Right after loading the PKCS#11 module, all smartcard slots are | |
679 | searched for certificates. The result can be viewed using | |
680 | the command | |
681 | ||
682 | ipsec auto --listcards | |
683 | ||
684 | The certificate objects found in the slots are numbered | |
685 | starting with #1, #2, etc. This position number can be used to address | |
686 | certificates (leftcert=%smartcard) and keys (: PIN %smartcard) | |
687 | in ipsec.conf and ipsec.secrets, respectively: | |
688 | ||
689 | %smartcard (selects object #1) | |
690 | %smartcard#1 (selects object #1) | |
691 | %smartcard#3 (selects object #3) | |
692 | ||
693 | As an alternative the existing retrieval scheme can be used: | |
694 | ||
695 | %smartcard:45 (selects object with id=45) | |
696 | %smartcard0 (selects first object in slot 0) | |
697 | %smartcard4:45 (selects object in slot 4 with id=45) | |
698 | ||
699 | - Depending on the settings of CKA_SIGN and CKA_DECRYPT | |
700 | private key flags either C_Sign() or C_Decrypt() is used | |
701 | to generate a signature. | |
702 | ||
703 | - The output buffer length parameter siglen in C_Sign() | |
704 | is now initialized to the actual size of the output | |
705 | buffer prior to the function call. This fixes the | |
706 | CKR_BUFFER_TOO_SMALL error that could occur when using | |
707 | the OpenSC PKCS#11 module. | |
708 | ||
709 | - Changed the initialization of the PKCS#11 CK_MECHANISM in | |
710 | C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }. | |
711 | ||
712 | - Refactored the RSA public/private key code and transferred it | |
713 | from keys.c to the new pkcs1.c file as a preparatory step | |
714 | towards the release of the SCEP client. | |
715 | ||
716 | ||
717 | strongswan-2.5.0 | |
718 | ---------------- | |
719 | ||
720 | - The loading of a PKCS#11 smartcard library module during | |
721 | runtime does not require OpenSC library functions any more | |
722 | because the corresponding code has been integrated into | |
723 | smartcard.c. Also the RSAREF pkcs11 header files have been | |
724 | included in a newly created pluto/rsaref directory so that | |
725 | no external include path has to be defined any longer. | |
726 | ||
727 | - A long-awaited feature has been implemented at last: | |
728 | The local caching of CRLs fetched via HTTP or LDAP, activated | |
729 | by the parameter cachecrls=yes in the config setup section | |
730 | of ipsec.conf. The dynamically fetched CRLs are stored under | |
731 | a unique file name containing the issuer's subjectKeyID | |
732 | in /etc/ipsec.d/crls. | |
733 | ||
734 | - Applied a one-line patch courtesy of Michael Richardson | |
735 | from the Openswan project which fixes the kernel-oops | |
736 | in KLIPS when an snmp daemon is running on the same box. | |
737 | ||
738 | ||
739 | strongswan-2.4.4 | |
740 | ---------------- | |
741 | ||
742 | - Eliminated null length CRL distribution point strings. | |
743 | ||
744 | - Fixed a trust path evaluation bug introduced with 2.4.3 | |
745 | ||
746 | ||
747 | strongswan-2.4.3 | |
748 | ---------------- | |
749 | ||
750 | - Improved the joint OCSP / CRL revocation policy. | |
751 | OCSP responses have precedence over CRL entries. | |
752 | ||
753 | - Introduced support of CRLv2 reason codes. | |
754 | ||
755 | - Fixed a bug with key-pad equipped readers which caused | |
756 | pluto to prompt for the pin via the console when the first | |
757 | occasion to enter the pin via the key-pad was missed. | |
758 | ||
759 | - When pluto is built with LDAP_V3 enabled, the library | |
760 | liblber required by newer versions of openldap is now | |
761 | included. | |
762 | ||
763 | ||
764 | strongswan-2.4.2 | |
765 | ---------------- | |
766 | ||
767 | - Added the _updown_espmark template which requires all | |
768 | incoming ESP traffic to be marked with a default mark | |
769 | value of 50. | |
770 | ||
771 | - Introduced the pkcs11keepstate parameter in the config setup | |
772 | section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11 | |
773 | session and login states are kept as long as possible during | |
774 | the lifetime of pluto. This means that a PIN entry via a key | |
775 | pad has to be done only once. | |
776 | ||
777 | - Introduced the pkcs11module parameter in the config setup | |
778 | section of ipsec.conf which specifies the PKCS#11 module | |
779 | to be used with smart cards. Example: | |
780 | ||
781 | pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo | |
782 | ||
783 | - Added support of smartcard readers equipped with a PIN pad. | |
784 | ||
785 | - Added patch by Jay Pfeifer which detects when netkey | |
786 | modules have been statically built into the Linux 2.6 kernel. | |
787 | ||
788 | - Added two patches by Herbert Xu. The first uses ip xfrm | |
789 | instead of setkey to flush the IPsec policy database. The | |
790 | second sets the optional flag in inbound IPComp SAs only. | |
791 | ||
792 | - Applied Ulrich Weber's patch which fixes an interoperability | |
793 | problem between native IPsec and KLIPS systems caused by | |
794 | setting the replay window to 32 instead of 0 for ipcomp. | |
795 | ||
796 | ||
797 | strongswan-2.4.1 | |
798 | ---------------- | |
799 | ||
800 | - Fixed a bug which caused an unwanted Mode Config request | |
801 | to be initiated in the case where "right" was used to denote | |
802 | the local side in ipsec.conf and "left" the remote side, | |
803 | contrary to the recommendation that "right" be remote and | |
804 | "left" be"local". | |
805 | ||
806 | ||
807 | strongswan-2.4.0a | |
808 | ----------------- | |
809 | ||
810 | - updated Vendor ID to strongSwan-2.4.0 | |
811 | ||
812 | - updated copyright statement to include David Buechi and | |
813 | Michael Meier | |
814 | ||
815 | ||
816 | strongswan-2.4.0 | |
817 | ---------------- | |
818 | ||
819 | - strongSwan now communicates with attached smartcards and | |
820 | USB crypto tokens via the standardized PKCS #11 interface. | |
821 | By default the OpenSC library from www.opensc.org is used | |
822 | but any other PKCS#11 library could be dynamically linked. | |
823 | strongSwan's PKCS#11 API was implemented by David Buechi | |
824 | and Michael Meier, both graduates of the Zurich University | |
825 | of Applied Sciences in Winterthur, Switzerland. | |
826 | ||
827 | - When a %trap eroute is triggered by an outgoing IP packet | |
828 | then the native IPsec stack of the Linux 2.6 kernel [often/ | |
829 | always?] returns an XFRM_ACQUIRE message with an undefined | |
830 | protocol family field and the connection setup fails. | |
831 | As a workaround IPv4 (AF_INET) is now assumed. | |
832 | ||
833 | - the results of the UML test scenarios are now enhanced | |
834 | with block diagrams of the virtual network topology used | |
835 | in a particular test. | |
836 | ||
837 | ||
838 | strongswan-2.3.2 | |
839 | ---------------- | |
840 | ||
841 | - fixed IV used to decrypt informational messages. | |
842 | This bug was introduced with Mode Config functionality. | |
843 | ||
844 | - fixed NCP Vendor ID. | |
845 | ||
846 | - undid one of Ulrich Weber's maximum udp size patches | |
847 | because it caused a segmentation fault with NAT-ed | |
848 | Delete SA messages. | |
849 | ||
850 | - added UML scenarios wildcards and attr-cert which | |
851 | demonstrate the implementation of IPsec policies based | |
852 | on wildcard parameters contained in Distinguished Names and | |
853 | on X.509 attribute certificates, respectively. | |
854 | ||
855 | ||
856 | strongswan-2.3.1 | |
857 | ---------------- | |
858 | ||
859 | - Added basic Mode Config functionality | |
860 | ||
861 | - Added Mathieu Lafon's patch which upgrades the status of | |
862 | the NAT-Traversal implementation to RFC 3947. | |
863 | ||
864 | - The _startklips script now also loads the xfrm4_tunnel | |
865 | module. | |
866 | ||
867 | - Added Ulrich Weber's netlink replay window size and | |
868 | maximum udp size patches. | |
869 | ||
870 | - UML testing now uses the Linux 2.6.10 UML kernel by default. | |
871 | ||
872 | ||
873 | strongswan-2.3.0 | |
874 | ---------------- | |
875 | ||
876 | - Eric Marchionni and Patrik Rayo, both recent graduates from | |
877 | the Zuercher Hochschule Winterthur in Switzerland, created a | |
878 | User-Mode-Linux test setup for strongSwan. For more details | |
879 | please read the INSTALL and README documents in the testing | |
880 | subdirectory. | |
881 | ||
882 | - Full support of group attributes based on X.509 attribute | |
883 | certificates. Attribute certificates can be generated | |
884 | using the openac facility. For more details see | |
885 | ||
886 | man ipsec_openac. | |
887 | ||
888 | The group attributes can be used in connection definitions | |
889 | in order to give IPsec access to specific user groups. | |
890 | This is done with the new parameter left|rightgroups as in | |
891 | ||
892 | rightgroups="Research, Sales" | |
893 | ||
894 | giving access to users possessing the group attributes | |
895 | Research or Sales, only. | |
896 | ||
897 | - In Quick Mode clients with subnet mask /32 are now | |
898 | coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should | |
899 | fix rekeying problems with the SafeNet/SoftRemote and NCP | |
900 | Secure Entry Clients. | |
901 | ||
902 | - Changed the defaults of the ikelifetime and keylife parameters | |
903 | to 3h and 1h, respectively. The maximum allowable values are | |
904 | now both set to 24 h. | |
905 | ||
906 | - Suppressed notification wars between two IPsec peers that | |
907 | could e.g. be triggered by incorrect ISAKMP encryption. | |
908 | ||
909 | - Public RSA keys can now have identical IDs if either the | |
910 | issuing CA or the serial number is different. The serial | |
911 | number of a certificate is now shown by the command | |
912 | ||
913 | ipsec auto --listpubkeys | |
914 | ||
915 | ||
916 | strongswan-2.2.2 | |
917 | ---------------- | |
918 | ||
919 | - Added Tuomo Soini's sourceip feature which allows a strongSwan | |
920 | roadwarrior to use a fixed Virtual IP (see README section 2.6) | |
921 | and reduces the well-known four tunnel case on VPN gateways to | |
922 | a single tunnel definition (see README section 2.4). | |
923 | ||
924 | - Fixed a bug occuring with NAT-Traversal enabled when the responder | |
925 | suddenly turns initiator and the initiator cannot find a matching | |
926 | connection because of the floated IKE port 4500. | |
927 | ||
928 | - Removed misleading ipsec verify command from barf. | |
929 | ||
930 | - Running under the native IP stack, ipsec --version now shows | |
931 | the Linux kernel version (courtesy to the Openswan project). | |
932 | ||
933 | ||
934 | strongswan-2.2.1 | |
935 | ---------------- | |
936 | ||
937 | - Introduced the ipsec auto --listalgs monitoring command which lists | |
938 | all currently registered IKE and ESP algorithms. | |
939 | ||
940 | - Fixed a bug in the ESP algorithm selection occuring when the strict flag | |
941 | is set and the first proposed transform does not match. | |
942 | ||
943 | - Fixed another deadlock in the use of the lock_certs_and_keys() mutex, | |
944 | occuring when a smartcard is present. | |
945 | ||
946 | - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event. | |
947 | ||
948 | - Fixed the printing of the notification names (null) | |
949 | ||
950 | - Applied another of Herbert Xu's Netlink patches. | |
951 | ||
952 | ||
953 | strongswan-2.2.0 | |
954 | ---------------- | |
955 | ||
956 | - Support of Dead Peer Detection. The connection parameter | |
957 | ||
958 | dpdaction=clear|hold | |
959 | ||
960 | activates DPD for the given connection. | |
961 | ||
962 | - The default Opportunistic Encryption (OE) policy groups are not | |
963 | automatically included anymore. Those wishing to activate OE can include | |
964 | the policy group with the following statement in ipsec.conf: | |
965 | ||
966 | include /etc/ipsec.d/examples/oe.conf | |
967 | ||
968 | The default for [right|left]rsasigkey is now set to %cert. | |
969 | ||
970 | - strongSwan now has a Vendor ID of its own which can be activated | |
971 | using the compile option VENDORID | |
972 | ||
973 | - Applied Herbert Xu's patch which sets the compression algorithm correctly. | |
974 | ||
975 | - Applied Herbert Xu's patch fixing an ESPINUDP problem | |
976 | ||
977 | - Applied Herbert Xu's patch setting source/destination port numbers. | |
978 | ||
979 | - Reapplied one of Herbert Xu's NAT-Traversal patches which got | |
980 | lost during the migration from SuperFreeS/WAN. | |
981 | ||
982 | - Fixed a deadlock in the use of the lock_certs_and_keys() mutex. | |
983 | ||
984 | - Fixed the unsharing of alg parameters when instantiating group | |
985 | connection. | |
986 | ||
987 | ||
988 | strongswan-2.1.5 | |
989 | ---------------- | |
990 | ||
991 | - Thomas Walpuski made me aware of a potential DoS attack via | |
992 | a PKCS#7-wrapped certificate bundle which could overwrite valid CA | |
993 | certificates in Pluto's authority certificate store. This vulnerability | |
994 | was fixed by establishing trust in CA candidate certificates up to a | |
995 | trusted root CA prior to insertion into Pluto's chained list. | |
996 | ||
997 | - replaced the --assign option by the -v option in the auto awk script | |
998 | in order to make it run with mawk under debian/woody. | |
999 | ||
1000 | ||
1001 | strongswan-2.1.4 | |
1002 | ---------------- | |
1003 | ||
1004 | - Split of the status information between ipsec auto --status (concise) | |
1005 | and ipsec auto --statusall (verbose). Both commands can be used with | |
1006 | an optional connection selector: | |
1007 | ||
1008 | ipsec auto --status[all] <connection_name> | |
1009 | ||
1010 | - Added the description of X.509 related features to the ipsec_auto(8) | |
1011 | man page. | |
1012 | ||
1013 | - Hardened the ASN.1 parser in debug mode, especially the printing | |
1014 | of malformed distinguished names. | |
1015 | ||
1016 | - The size of an RSA public key received in a certificate is now restricted to | |
1017 | ||
1018 | 512 bits <= modulus length <= 8192 bits. | |
1019 | ||
1020 | - Fixed the debug mode enumeration. | |
1021 | ||
1022 | ||
1023 | strongswan-2.1.3 | |
1024 | ---------------- | |
1025 | ||
1026 | - Fixed another PKCS#7 vulnerability which could lead to an | |
1027 | endless loop while following the X.509 trust chain. | |
1028 | ||
1029 | ||
1030 | strongswan-2.1.2 | |
1031 | ---------------- | |
1032 | ||
1033 | - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski | |
1034 | that accepted end certificates having identical issuer and subject | |
1035 | distinguished names in a multi-tier X.509 trust chain. | |
1036 | ||
1037 | ||
1038 | strongswan-2.1.1 | |
1039 | ---------------- | |
1040 | ||
1041 | - Removed all remaining references to ipsec_netlink.h in KLIPS. | |
1042 | ||
1043 | ||
1044 | strongswan-2.1.0 | |
1045 | ---------------- | |
1046 | ||
1047 | - The new "ca" section allows to define the following parameters: | |
1048 | ||
1049 | ca kool | |
1050 | cacert=koolCA.pem # cacert of kool CA | |
1051 | ocspuri=http://ocsp.kool.net:8001 # ocsp server | |
1052 | ldapserver=ldap.kool.net # default ldap server | |
1053 | crluri=http://www.kool.net/kool.crl # crl distribution point | |
1054 | crluri2="ldap:///O=Kool, C= .." # crl distribution point #2 | |
1055 | auto=add # add, ignore | |
1056 | ||
1057 | The ca definitions can be monitored via the command | |
1058 | ||
1059 | ipsec auto --listcainfos | |
1060 | ||
1061 | - Fixed cosmetic corruption of /proc filesystem by integrating | |
1062 | D. Hugh Redelmeier's freeswan-2.06 kernel fixes. | |
1063 | ||
1064 | ||
1065 | strongswan-2.0.2 | |
1066 | ---------------- | |
1067 | ||
1068 | - Added support for the 818043 NAT-Traversal update of Microsoft's | |
1069 | Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode. | |
1070 | ||
1071 | - A symbolic link to libcrypto is now added in the kernel sources | |
1072 | during kernel compilation | |
1073 | ||
1074 | - Fixed a couple of 64 bit issues (mostly casts to int). | |
1075 | Thanks to Ken Bantoft who checked my sources on a 64 bit platform. | |
1076 | ||
1077 | - Replaced s[n]printf() statements in the kernel by ipsec_snprintf(). | |
1078 | Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro | |
1079 | of the FreeS/WAN team who solved this problem with the 2.4.25 kernel. | |
1080 | ||
1081 | ||
1082 | strongswan-2.0.1 | |
1083 | ---------------- | |
1084 | ||
1085 | - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName | |
1086 | certificate extension which contains no generalName item) can cause | |
1087 | a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has | |
1088 | been hardened to make it more robust against malformed ASN.1 objects. | |
1089 | ||
1090 | - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native | |
1091 | Linux 2.6 IPsec stack. | |
1092 | ||
1093 | ||
1094 | strongswan-2.0.0 | |
1095 | ---------------- | |
1096 | ||
1097 | - based on freeswan-2.04, x509-1.5.3, nat-0.6c, alg-0.8.1rc12 |
