4 - Sansar Choinyambuu implemented the RFC 5793 Posture Broker Protocol (BP)
5 compatible with Trusted Network Connect (TNC). The TNCCS 2.0 protocol
6 requires the tnccs_20, tnc_imc and tnc_imv plugins but does not depend
7 on the libtnc library. Any available IMV/IMC pairs conforming to the
8 Trusted Computing Group's TNC-IF-IMV/IMC 1.2 interface specification
9 can be loaded via /etc/tnc_config.
11 - Re-implemented the TNCCS 1.1 protocol by using the tnc_imc and tnc_imv
12 in place of the external libtnc library.
14 - The tnccs_dynamic plugin loaded on a TNC server in addition to the
15 tnccs_11 and tnccs_20 plugins, dynamically detects the IF-TNCCS
16 protocol version used by a TNC client and invokes an instance of
17 the corresponding protocol stack.
19 - IKE and ESP proposals can now be stored in an SQL database using a
20 new proposals table. The start_action field in the child_configs
21 tables allows the automatic starting or routing of connections stored
24 - The new certificate_authorities and certificate_distribution_points
25 tables make it possible to store CRL and OCSP Certificate Distribution
26 points in an SQL database.
28 - The new 'include' statement allows to recursively include other files in
29 strongswan.conf. Existing sections and values are thereby extended and
30 replaced, respectively.
32 - Due to the changes in the parser for strongswan.conf, the configuration
33 syntax for the attr plugin has changed. Previously, it was possible to
34 specify multiple values of a specific attribute type by adding multiple
35 key/value pairs with the same key (e.g. dns) to the plugins.attr section.
36 Because values with the same key now replace previously defined values
37 this is not possible anymore. As an alternative, multiple values can be
38 specified by separating them with a comma (e.g. dns = 1.2.3.4, 2.3.4.5).
40 - ipsec listalgs now appends (set in square brackets) to each crypto
41 algorithm listed the plugin that registered the function.
43 - Traffic Flow Confidentiality padding supported with Linux 2.6.38 can be used
44 by the IKEv2 daemon. The ipsec.conf 'tfc' keyword pads all packets to a given
45 boundary, the special value '%mtu' pads all packets to the path MTU.
47 - The new af-alg plugin can use various crypto primitives of the Linux Crypto
48 API using the AF_ALG interface introduced with 2.6.38. This removes the need
49 for additional userland implementations of symmetric cipher, hash, hmac and
52 - The IKEv2 daemon supports the INITIAL_CONTACT notify as initiator and
53 responder. The notify is sent when initiating configurations with a unique
54 policy, set in ipsec.conf via the global 'uniqueids' option.
56 - The conftest conformance testing framework enables the IKEv2 stack to perform
57 many tests using a distinct tool and configuration frontend. Various hooks
58 can alter reserved bits, flags, add custom notifies and proposals, reorder
59 or drop messages and much more. It is enabled using the --enable-conftest
62 - The new libstrongswan constraints plugin provides advanced X.509 constraint
63 checking. In additon to X.509 pathLen constraints, the plugin checks for
64 nameConstraints and certificatePolicies, including policyMappings and
65 policyConstraints. The x509 certificate plugin and the pki tool have been
66 enhanced to support these extensions. The new left/rightcertpolicy ipsec.conf
67 connection keywords take OIDs a peer certificate must have.
69 - The left/rightauth ipsec.conf keywords accept values with a minimum strength
70 for trustchain public keys in bits, such as rsa-2048 or ecdsa-256.
72 - The revocation and x509 libstrongswan plugins and the pki tool gained basic
73 support for delta CRLs.
79 - IMPORTANT: the default keyexchange mode 'ike' is changing with release 4.5
80 from 'ikev1' to 'ikev2', thus commemorating the five year anniversary of the
81 IKEv2 RFC 4306 and its mature successor RFC 5996. The time has definitively
82 come for IKEv1 to go into retirement and to cede its place to the much more
83 robust, powerful and versatile IKEv2 protocol!
85 - Added new ctr, ccm and gcm plugins providing Counter, Counter with CBC-MAC
86 and Galois/Counter Modes based on existing CBC implementations. These
87 new plugins bring support for AES and Camellia Counter and CCM algorithms
88 and the AES GCM algorithms for use in IKEv2.
90 - The new pkcs11 plugin brings full Smartcard support to the IKEv2 daemon and
91 the pki utility using one or more PKCS#11 libraries. It currently supports
92 RSA private and public key operations and loads X.509 certificates from
95 - Implemented a general purpose TLS stack based on crypto and credential
96 primitives of libstrongswan. libtls supports TLS versions 1.0, 1.1 and 1.2,
97 ECDHE-ECDSA/RSA, DHE-RSA and RSA key exchange algorithms and RSA/ECDSA based
98 client authentication.
100 - Based on libtls, the eap-tls plugin brings certificate based EAP
101 authentication for client and server. It is compatible to Windows 7 IKEv2
102 Smartcard authentication and the OpenSSL based FreeRADIUS EAP-TLS backend.
104 - Implemented the TNCCS 1.1 Trusted Network Connect protocol using the
105 libtnc library on the strongSwan client and server side via the tnccs_11
106 plugin and optionally connecting to a TNC@FHH-enhanced FreeRADIUS AAA server.
107 Depending on the resulting TNC Recommendation, strongSwan clients are granted
108 access to a network behind a strongSwan gateway (allow), are put into a
109 remediation zone (isolate) or are blocked (none), respectively. Any number
110 of Integrity Measurement Collector/Verifier pairs can be attached
111 via the tnc-imc and tnc-imv charon plugins.
113 - The IKEv1 daemon pluto now uses the same kernel interfaces as the IKEv2
114 daemon charon. As a result of this, pluto now supports xfrm marks which
115 were introduced in charon with 4.4.1.
117 - Applets for Maemo 5 (Nokia) allow to easily configure and control IKEv2
118 based VPN connections with EAP authentication on supported devices.
120 - The RADIUS plugin eap-radius now supports multiple RADIUS servers for
121 redundant setups. Servers are selected by a defined priority, server load and
124 - The simple led plugin controls hardware LEDs through the Linux LED subsystem.
125 It currently shows activity of the IKE daemon and is a good example how to
126 implement a simple event listener.
128 - Improved MOBIKE behavior in several corner cases, for instance, if the
129 initial responder moves to a different address.
131 - Fixed left-/rightnexthop option, which was broken since 4.4.0.
133 - Fixed a bug not releasing a virtual IP address to a pool if the XAUTH
134 identity was different from the IKE identity.
136 - Fixed the alignment of ModeConfig messages on 4-byte boundaries in the
137 case where the attributes are not a multiple of 4 bytes (e.g. Cisco's
140 - Fixed the interoperability of the socket_raw and socket_default
143 - Added man page for strongswan.conf
149 - Support of xfrm marks in IPsec SAs and IPsec policies introduced
150 with the Linux 2.6.34 kernel. For details see the example scenarios
151 ikev2/nat-two-rw-mark, ikev2/rw-nat-mark-in-out and ikev2/net2net-psk-dscp.
153 - The PLUTO_MARK_IN and PLUTO_ESP_ENC environment variables can be used
154 in a user-specific updown script to set marks on inbound ESP or
157 - The openssl plugin now supports X.509 certificate and CRL functions.
159 - OCSP/CRL checking in IKEv2 has been moved to the revocation plugin, enabled
160 by default. Plase update manual load directives in strongswan.conf.
162 - RFC3779 ipAddrBlock constraint checking has been moved to the addrblock
163 plugin, disabled by default. Enable it and update manual load directives
164 in strongswan.conf, if required.
166 - The pki utility supports CRL generation using the --signcrl command.
168 - The ipsec pki --self, --issue and --req commands now support output in
169 PEM format using the --outform pem option.
171 - The major refactoring of the IKEv1 Mode Config functionality now allows
172 the transport and handling of any Mode Config attribute.
174 - The RADIUS proxy plugin eap-radius now supports multiple servers. Configured
175 servers are chosen randomly, with the option to prefer a specific server.
176 Non-responding servers are degraded by the selection process.
178 - The ipsec pool tool manages arbitrary configuration attributes stored
179 in an SQL database. ipsec pool --help gives the details.
181 - The new eap-simaka-sql plugin acts as a backend for EAP-SIM and EAP-AKA,
182 reading triplets/quintuplets from an SQL database.
184 - The High Availability plugin now supports a HA enabled in-memory address
185 pool and Node reintegration without IKE_SA rekeying. The latter allows
186 clients without IKE_SA rekeying support to keep connected during
187 reintegration. Additionally, many other issues have been fixed in the ha
190 - Fixed a potential remote code execution vulnerability resulting from
191 the misuse of snprintf(). The vulnerability is exploitable by
192 unauthenticated users.
198 - The IKEv2 High Availability plugin has been integrated. It provides
199 load sharing and failover capabilities in a cluster of currently two nodes,
200 based on an extend ClusterIP kernel module. More information is available at
201 http://wiki.strongswan.org/projects/strongswan/wiki/HighAvailability.
202 The development of the High Availability functionality was sponsored by
203 secunet Security Networks AG.
205 - Added IKEv1 and IKEv2 configuration support for the AES-GMAC
206 authentication-only ESP cipher. Our aes_gmac kernel patch or a Linux
207 2.6.34 kernel is required to make AES-GMAC available via the XFRM
210 - Added support for Diffie-Hellman groups 22, 23 and 24 to the gmp, gcrypt
211 and openssl plugins, usable by both pluto and charon. The new proposal
212 keywords are modp1024s160, modp2048s224 and modp2048s256. Thanks to Joy Latten
213 from IBM for his contribution.
215 - The IKEv1 pluto daemon supports RAM-based virtual IP pools using
216 the rightsourceip directive with a subnet from which addresses
219 - The ipsec pki --gen and --pub commands now allow the output of
220 private and public keys in PEM format using the --outform pem
223 - The new DHCP plugin queries virtual IP addresses for clients from a DHCP
224 server using broadcasts, or a defined server using the
225 charon.plugins.dhcp.server strongswan.conf option. DNS/WINS server information
226 is additionally served to clients if the DHCP server provides such
227 information. The plugin is used in ipsec.conf configurations having
228 rightsourceip set to %dhcp.
230 - A new plugin called farp fakes ARP responses for virtual IP addresses
231 handed out to clients from the IKEv2 daemon charon. The plugin lets a
232 road-warrior act as a client on the local LAN if it uses a virtual IP
233 from the responders subnet, e.g. acquired using the DHCP plugin.
235 - The existing IKEv2 socket implementations have been migrated to the
236 socket-default and the socket-raw plugins. The new socket-dynamic plugin
237 binds sockets dynamically to ports configured via the left-/rightikeport
238 ipsec.conf connection parameters.
240 - The android charon plugin stores received DNS server information as "net.dns"
241 system properties, as used by the Android platform.
247 - The IKEv2 daemon supports RFC 3779 IP address block constraints
248 carried as a critical X.509v3 extension in the peer certificate.
250 - The ipsec pool --add|del dns|nbns command manages DNS and NBNS name
251 server entries that are sent via the IKEv1 Mode Config or IKEv2
252 Configuration Payload to remote clients.
254 - The Camellia cipher can be used as an IKEv1 encryption algorithm.
256 - The IKEv1 and IKEV2 daemons now check certificate path length constraints.
258 - The new ipsec.conf conn option "inactivity" closes a CHILD_SA if no traffic
259 was sent or received within the given interval. To close the complete IKE_SA
260 if its only CHILD_SA was inactive, set the global strongswan.conf option
261 "charon.inactivity_close_ike" to yes.
263 - More detailed IKEv2 EAP payload information in debug output
265 - IKEv2 EAP-SIM and EAP-AKA share joint libsimaka library
267 - Added required userland changes for proper SHA256 and SHA384/512 in ESP that
268 will be introduced with Linux 2.6.33. The "sha256"/"sha2_256" keyword now
269 configures the kernel with 128 bit truncation, not the non-standard 96
270 bit truncation used by previous releases. To use the old 96 bit truncation
271 scheme, the new "sha256_96" proposal keyword has been introduced.
273 - Fixed IPComp in tunnel mode, stripping out the duplicated outer header. This
274 change makes IPcomp tunnel mode connections incompatible with previous
275 releases; disable compression on such tunnels.
277 - Fixed BEET mode connections on recent kernels by installing SAs with
278 appropriate traffic selectors, based on a patch by Michael Rossberg.
280 - Using extensions (such as BEET mode) and crypto algorithms (such as twofish,
281 serpent, sha256_96) allocated in the private use space now require that we
282 know its meaning, i.e. we are talking to strongSwan. Use the new
283 "charon.send_vendor_id" option in strongswan.conf to let the remote peer know
286 - Experimental support for draft-eronen-ipsec-ikev2-eap-auth, where the
287 responder omits public key authentication in favor of a mutual authentication
288 method. To enable EAP-only authentication, set rightauth=eap on the responder
289 to rely only on the MSK constructed AUTH payload. This not-yet standardized
290 extension requires the strongSwan vendor ID introduced above.
292 - The IKEv1 daemon ignores the Juniper SRX notification type 40001, thus
293 allowing interoperability.
299 - The IKEv1 pluto daemon can now use SQL-based address pools to deal out
300 virtual IP addresses as a Mode Config server. The pool capability has been
301 migrated from charon's sql plugin to a new attr-sql plugin which is loaded
302 by libstrongswan and which can be used by both daemons either with a SQLite
303 or MySQL database and the corresponding plugin.
305 - Plugin names have been streamlined: EAP plugins now have a dash after eap
306 (e.g. eap-sim), as it is used with the --enable-eap-sim ./configure option.
307 Plugin configuration sections in strongswan.conf now use the same name as the
308 plugin itself (i.e. with a dash). Make sure to update "load" directives and
309 the affected plugin sections in existing strongswan.conf files.
311 - The private/public key parsing and encoding has been split up into
312 separate pkcs1, pgp, pem and dnskey plugins. The public key implementation
313 plugins gmp, gcrypt and openssl can all make use of them.
315 - The EAP-AKA plugin can use different backends for USIM/quintuplet
316 calculations, very similar to the EAP-SIM plugin. The existing 3GPP2 software
317 implementation has been migrated to a separate plugin.
319 - The IKEv2 daemon charon gained basic PGP support. It can use locally installed
320 peer certificates and can issue signatures based on RSA private keys.
322 - The new 'ipsec pki' tool provides a set of commands to maintain a public
323 key infrastructure. It currently supports operations to create RSA and ECDSA
324 private/public keys, calculate fingerprints and issue or verify certificates.
326 - Charon uses a monotonic time source for statistics and job queueing, behaving
327 correctly if the system time changes (e.g. when using NTP).
329 - In addition to time based rekeying, charon supports IPsec SA lifetimes based
330 on processed volume or number of packets. They new ipsec.conf paramaters
331 'lifetime' (an alias to 'keylife'), 'lifebytes' and 'lifepackets' handle
332 SA timeouts, while the parameters 'margintime' (an alias to rekeymargin),
333 'marginbytes' and 'marginpackets' trigger the rekeying before a SA expires.
334 The existing parameter 'rekeyfuzz' affects all margins.
336 - If no CA/Gateway certificate is specified in the NetworkManager plugin,
337 charon uses a set of trusted root certificates preinstalled by distributions.
338 The directory containing CA certificates can be specified using the
339 --with-nm-ca-dir=path configure option.
341 - Fixed the encoding of the Email relative distinguished name in left|rightid
344 - Fixed the broken parsing of PKCS#7 wrapped certificates by the pluto daemon.
346 - Fixed smartcard-based authentication in the pluto daemon which was broken by
347 the ECDSA support introduced with the 4.3.2 release.
349 - A patch contributed by Heiko Hund fixes mixed IPv6 in IPv4 and vice versa
350 tunnels established with the IKEv1 pluto daemon.
352 - The pluto daemon now uses the libstrongswan x509 plugin for certificates and
353 CRls and the struct id type was replaced by identification_t used by charon
354 and the libstrongswan library.
360 - IKEv2 charon daemon ported to FreeBSD and Mac OS X. Installation details can
361 be found on wiki.strongswan.org.
363 - ipsec statusall shows the number of bytes transmitted and received over
364 ESP connections configured by the IKEv2 charon daemon.
366 - The IKEv2 charon daemon supports include files in ipsec.secrets.
372 - The configuration option --enable-integrity-test plus the strongswan.conf
373 option libstrongswan.integrity_test = yes activate integrity tests
374 of the IKE daemons charon and pluto, libstrongswan and all loaded
375 plugins. Thus dynamic library misconfigurations and non-malicious file
376 manipulations can be reliably detected.
378 - The new default setting libstrongswan.ecp_x_coordinate_only=yes allows
379 IKEv1 interoperability with MS Windows using the ECP DH groups 19 and 20.
381 - The IKEv1 pluto daemon now supports the AES-CCM and AES-GCM ESP
382 authenticated encryption algorithms.
384 - The IKEv1 pluto daemon now supports V4 OpenPGP keys.
386 - The RDN parser vulnerability discovered by Orange Labs research team
387 was not completely fixed in version 4.3.2. Some more modifications
388 had to be applied to the asn1_length() function to make it robust.
394 - The new gcrypt plugin provides symmetric cipher, hasher, RNG, Diffie-Hellman
395 and RSA crypto primitives using the LGPL licensed GNU gcrypt library.
397 - libstrongswan features an integrated crypto selftest framework for registered
398 algorithms. The test-vector plugin provides a first set of test vectors and
399 allows pluto and charon to rely on tested crypto algorithms.
401 - pluto can now use all libstrongswan plugins with the exception of x509 and xcbc.
402 Thanks to the openssl plugin, the ECP Diffie-Hellman groups 19, 20, 21, 25, and
403 26 as well as ECDSA-256, ECDSA-384, and ECDSA-521 authentication can be used
406 - Applying their fuzzing tool, the Orange Labs vulnerability research team found
407 another two DoS vulnerabilities, one in the rather old ASN.1 parser of Relative
408 Distinguished Names (RDNs) and a second one in the conversion of ASN.1 UTCTIME
409 and GENERALIZEDTIME strings to a time_t value.
415 - The nm plugin now passes DNS/NBNS server information to NetworkManager,
416 allowing a gateway administrator to set DNS/NBNS configuration on clients
419 - The nm plugin also accepts CA certificates for gateway authentication. If
420 a CA certificate is configured, strongSwan uses the entered gateway address
421 as its idenitity, requiring the gateways certificate to contain the same as
422 subjectAltName. This allows a gateway administrator to deploy the same
423 certificates to Windows 7 and NetworkManager clients.
425 - The command ipsec purgeike deletes IKEv2 SAs that don't have a CHILD SA.
426 The command ipsec down <conn>{n} deletes CHILD SA instance n of connection
427 <conn> whereas ipsec down <conn>{*} deletes all CHILD SA instances.
428 The command ipsec down <conn>[n] deletes IKE SA instance n of connection
429 <conn> plus dependent CHILD SAs whereas ipsec down <conn>[*] deletes all
430 IKE SA instances of connection <conn>.
432 - Fixed a regression introduced in 4.3.0 where EAP authentication calculated
433 the AUTH payload incorrectly. Further, the EAP-MSCHAPv2 MSK key derivation
434 has been updated to be compatible with the Windows 7 Release Candidate.
436 - Refactored installation of triggering policies. Routed policies are handled
437 outside of IKE_SAs to keep them installed in any case. A tunnel gets
438 established only once, even if initiation is delayed due network outages.
440 - Improved the handling of multiple acquire signals triggered by the kernel.
442 - Fixed two DoS vulnerabilities in the charon daemon that were discovered by
443 fuzzing techniques: 1) Sending a malformed IKE_SA_INIT request leaved an
444 incomplete state which caused a null pointer dereference if a subsequent
445 CREATE_CHILD_SA request was sent. 2) Sending an IKE_AUTH request with either
446 a missing TSi or TSr payload caused a null pointer derefence because the
447 checks for TSi and TSr were interchanged. The IKEv2 fuzzer used was
448 developped by the Orange Labs vulnerability research team. The tool was
449 initially written by Gabriel Campana and is now maintained by Laurent Butti.
451 - Added support for AES counter mode in ESP in IKEv2 using the proposal
452 keywords aes128ctr, aes192ctr and aes256ctr.
454 - Further progress in refactoring pluto: Use of the curl and ldap plugins
455 for fetching crls and OCSP. Use of the random plugin to get keying material
456 from /dev/random or /dev/urandom. Use of the openssl plugin as an alternative
457 to the aes, des, sha1, sha2, and md5 plugins. The blowfish, twofish, and
458 serpent encryption plugins are now optional and are not enabled by default.
464 - Support for the IKEv2 Multiple Authentication Exchanges extension (RFC4739).
465 Initiators and responders can use several authentication rounds (e.g. RSA
466 followed by EAP) to authenticate. The new ipsec.conf leftauth/rightauth and
467 leftauth2/rightauth2 parameters define own authentication rounds or setup
468 constraints for the remote peer. See the ipsec.conf man page for more detials.
470 - If glibc printf hooks (register_printf_function) are not available,
471 strongSwan can use the vstr string library to run on non-glibc systems.
473 - The IKEv2 charon daemon can now configure the ESP CAMELLIA-CBC cipher
474 (esp=camellia128|192|256).
476 - Refactored the pluto and scepclient code to use basic functions (memory
477 allocation, leak detective, chunk handling, printf_hooks, strongswan.conf
478 attributes, ASN.1 parser, etc.) from the libstrongswan library.
480 - Up to two DNS and WINS servers to be sent via IKEv1 ModeConfig can be
481 configured in the pluto section of strongswan.conf.
487 - The new server-side EAP RADIUS plugin (--enable-eap-radius)
488 relays EAP messages to and from a RADIUS server. Succesfully
489 tested with with a freeradius server using EAP-MD5 and EAP-SIM.
491 - A vulnerability in the Dead Peer Detection (RFC 3706) code was found by
492 Gerd v. Egidy <gerd.von.egidy@intra2net.com> of Intra2net AG affecting
493 all Openswan and strongSwan releases. A malicious (or expired ISAKMP)
494 R_U_THERE or R_U_THERE_ACK Dead Peer Detection packet can cause the
495 pluto IKE daemon to crash and restart. No authentication or encryption
496 is required to trigger this bug. One spoofed UDP packet can cause the
497 pluto IKE daemon to restart and be unresponsive for a few seconds while
498 restarting. This DPD null state vulnerability has been officially
499 registered as CVE-2009-0790 and is fixed by this release.
501 - ASN.1 to time_t conversion caused a time wrap-around for
502 dates after Jan 18 03:14:07 UTC 2038 on 32-bit platforms.
503 As a workaround such dates are set to the maximum representable
504 time, i.e. Jan 19 03:14:07 UTC 2038.
506 - Distinguished Names containing wildcards (*) are not sent in the
513 - Fixed a use-after-free bug in the DPD timeout section of the
514 IKEv1 pluto daemon which sporadically caused a segfault.
516 - Fixed a crash in the IKEv2 charon daemon occuring with
517 mixed RAM-based and SQL-based virtual IP address pools.
519 - Fixed ASN.1 parsing of algorithmIdentifier objects where the
520 parameters field is optional.
522 - Ported nm plugin to NetworkManager 7.1.
528 - Support of the EAP-MSCHAPv2 protocol enabled by the option
529 --enable-eap-mschapv2. Requires the MD4 hash algorithm enabled
530 either by --enable-md4 or --enable-openssl.
532 - Assignment of up to two DNS and up to two WINS servers to peers via
533 the IKEv2 Configuration Payload (CP). The IPv4 or IPv6 nameserver
534 addresses are defined in strongswan.conf.
536 - The strongSwan applet for the Gnome NetworkManager is now built and
537 distributed as a separate tarball under the name NetworkManager-strongswan.
543 - Fixed ESP NULL encryption broken by the refactoring of keymat.c.
544 Also introduced proper initialization and disposal of keying material.
546 - Fixed the missing listing of connection definitions in ipsec statusall
547 broken by an unfortunate local variable overload.
553 - Several performance improvements to handle thousands of tunnels with almost
554 linear upscaling. All relevant data structures have been replaced by faster
555 counterparts with better lookup times.
557 - Better parallelization to run charon on multiple cores. Due to improved
558 ressource locking and other optimizations the daemon can take full
559 advantage of 16 or even more cores.
561 - The load-tester plugin can use a NULL Diffie-Hellman group and simulate
562 unique identities and certificates by signing peer certificates using a CA
565 - The redesigned stroke in-memory IP pool handles leases. The "ipsec leases"
566 command queries assigned leases.
568 - Added support for smartcards in charon by using the ENGINE API provided by
569 OpenSSL, based on patches by Michael Roßberg.
571 - The Padlock plugin supports the hardware RNG found on VIA CPUs to provide a
572 reliable source of randomness.
577 - Flexible configuration of logging subsystem allowing to log to multiple
578 syslog facilities or to files using fine-grained log levels for each target.
580 - Load testing plugin to do stress testing of the IKEv2 daemon against self
581 or another host. Found and fixed issues during tests in the multi-threaded
582 use of the OpenSSL plugin.
584 - Added profiling code to synchronization primitives to find bottlenecks if
585 running on multiple cores. Found and fixed an issue where parts of the
586 Diffie-Hellman calculation acquired an exclusive lock. This greatly improves
587 parallelization to multiple cores.
589 - updown script invocation has been separated into a plugin of its own to
590 further slim down the daemon core.
592 - Separated IKE_SA/CHILD_SA key derivation process into a closed system,
593 allowing future implementations to use a secured environment in e.g. kernel
596 - The kernel interface of charon has been modularized. XFRM NETLINK (default)
597 and PFKEY (--enable-kernel-pfkey) interface plugins for the native IPsec
598 stack of the Linux 2.6 kernel as well as a PFKEY interface for the KLIPS
599 IPsec stack (--enable-kernel-klips) are provided.
601 - Basic Mobile IPv6 support has been introduced, securing Binding Update
602 messages as well as tunneled traffic between Mobile Node and Home Agent.
603 The installpolicy=no option allows peaceful cooperation with a dominant
604 mip6d daemon and the new type=transport_proxy implements the special MIPv6
605 IPsec transport proxy mode where the IKEv2 daemon uses the Care-of-Address
606 but the IPsec SA is set up for the Home Adress.
608 - Implemented migration of Mobile IPv6 connections using the KMADDRESS
609 field contained in XFRM_MSG_MIGRATE messages sent by the mip6d daemon
610 via the Linux 2.6.28 (or appropriately patched) kernel.
616 - IKEv2 charon daemon supports authentication based on raw public keys
617 stored in the SQL database backend. The ipsec listpubkeys command
618 lists the available raw public keys via the stroke interface.
620 - Several MOBIKE improvements: Detect changes in NAT mappings in DPD exchanges,
621 handle events if kernel detects NAT mapping changes in UDP-encapsulated
622 ESP packets (requires kernel patch), reuse old addesses in MOBIKE updates as
623 long as possible and other fixes.
625 - Fixed a bug in addr_in_subnet() which caused insertion of wrong source
626 routes for destination subnets having netwmasks not being a multiple of 8 bits.
627 Thanks go to Wolfgang Steudel, TU Ilmenau for reporting this bug.
633 - Fixed a Denial-of-Service vulnerability where an IKE_SA_INIT message with
634 a KE payload containing zeroes only can cause a crash of the IKEv2 charon
635 daemon due to a NULL pointer returned by the mpz_export() function of the
636 GNU Multiprecision Library (GMP). Thanks go to Mu Dynamics Research Labs
637 for making us aware of this problem.
639 - The new agent plugin provides a private key implementation on top of an
642 - The NetworkManager plugin has been extended to support certificate client
643 authentication using RSA keys loaded from a file or using ssh-agent.
645 - Daemon capability dropping has been ported to libcap and must be enabled
646 explicitly --with-capabilities=libcap. Future version will support the
647 newer libcap2 library.
649 - ipsec listalgs lists the IKEv2 cryptografic algorithms registered with the
650 charon keying daemon.
656 - A NetworkManager plugin allows GUI-based configuration of road-warrior
657 clients in a simple way. It features X509 based gateway authentication
658 and EAP client authentication, tunnel setup/teardown and storing passwords
659 in the Gnome Keyring.
661 - A new EAP-GTC plugin implements draft-sheffer-ikev2-gtc-00.txt and allows
662 username/password authentication against any PAM service on the gateway.
663 The new EAP method interacts nicely with the NetworkManager plugin and allows
664 client authentication against e.g. LDAP.
666 - Improved support for the EAP-Identity method. The new ipsec.conf eap_identity
667 parameter defines an additional identity to pass to the server in EAP
670 - The "ipsec statusall" command now lists CA restrictions, EAP
671 authentication types and EAP identities.
673 - Fixed two multithreading deadlocks occurring when starting up
674 several hundred tunnels concurrently.
676 - Fixed the --enable-integrity-test configure option which
677 computes a SHA-1 checksum over the libstrongswan library.
683 - Consistent logging of IKE and CHILD SAs at the audit (AUD) level.
685 - Improved the performance of the SQL-based virtual IP address pool
686 by introducing an additional addresses table. The leases table
687 storing only history information has become optional and can be
688 disabled by setting charon.plugins.sql.lease_history = no in
691 - The XFRM_STATE_AF_UNSPEC flag added to xfrm.h allows IPv4-over-IPv6
692 and IPv6-over-IPv4 tunnels with the 2.6.26 and later Linux kernels.
694 - management of different virtual IP pools for different
695 network interfaces have become possible.
697 - fixed a bug which prevented the assignment of more than 256
698 virtual IP addresses from a pool managed by an sql database.
700 - fixed a bug which did not delete own IPCOMP SAs in the kernel.
706 - Added statistics functions to ipsec pool --status and ipsec pool --leases
707 and input validation checks to various ipsec pool commands.
709 - ipsec statusall now lists all loaded charon plugins and displays
710 the negotiated IKEv2 cipher suite proposals.
712 - The openssl plugin supports the elliptic curve Diffie-Hellman groups
713 19, 20, 21, 25, and 26.
715 - The openssl plugin supports ECDSA authentication using elliptic curve
718 - Fixed a bug in stroke which caused multiple charon threads to close
719 the file descriptors during packet transfers over the stroke socket.
721 - ESP sequence numbers are now migrated in IPsec SA updates handled by
722 MOBIKE. Works only with Linux kernels >= 2.6.17.
728 - Fixed the strongswan.conf path configuration problem that occurred when
729 --sysconfig was not set explicitly in ./configure.
731 - Fixed a number of minor bugs that where discovered during the 4th
732 IKEv2 interoperability workshop in San Antonio, TX.
738 - Plugins for libstrongswan and charon can optionally be loaded according
739 to a configuration in strongswan.conf. Most components provide a
740 "load = " option followed by a space separated list of plugins to load.
741 This allows e.g. the fallback from a hardware crypto accelerator to
742 to software-based crypto plugins.
744 - Charons SQL plugin has been extended by a virtual IP address pool.
745 Configurations with a rightsourceip=%poolname setting query a SQLite or
746 MySQL database for leases. The "ipsec pool" command helps in administrating
747 the pool database. See ipsec pool --help for the available options
749 - The Authenticated Encryption Algorithms AES-CCM-8/12/16 and AES-GCM-8/12/16
750 for ESP are now supported starting with the Linux 2.6.25 kernel. The
751 syntax is e.g. esp=aes128ccm12 or esp=aes256gcm16.
757 - Support for "Hash and URL" encoded certificate payloads has been implemented
758 in the IKEv2 daemon charon. Using the "certuribase" option of a CA section
759 allows to assign a base URL to all certificates issued by the specified CA.
760 The final URL is then built by concatenating that base and the hex encoded
761 SHA1 hash of the DER encoded certificate. Note that this feature is disabled
762 by default and must be enabled using the option "charon.hash_and_url".
764 - The IKEv2 daemon charon now supports the "uniqueids" option to close multiple
765 IKE_SAs with the same peer. The option value "keep" prefers existing
766 connection setups over new ones, where the value "replace" replaces existing
769 - The crypto factory in libstrongswan additionaly supports random number
770 generators, plugins may provide other sources of randomness. The default
771 plugin reads raw random data from /dev/(u)random.
773 - Extended the credential framework by a caching option to allow plugins
774 persistent caching of fetched credentials. The "cachecrl" option has been
777 - The new trustchain verification introduced in 4.2.0 has been parallelized.
778 Threads fetching CRL or OCSP information no longer block other threads.
780 - A new IKEv2 configuration attribute framework has been introduced allowing
781 plugins to provide virtual IP addresses, and in the future, other
782 configuration attribute services (e.g. DNS/WINS servers).
784 - The stroke plugin has been extended to provide virtual IP addresses from
785 a pool defined in ipsec.conf. The "rightsourceip" parameter now accepts
786 address pools in CIDR notation (e.g. 10.1.1.0/24). The parameter also accepts
787 the value "%poolname", where "poolname" identifies a pool provided by a
790 - Fixed compilation on uClibc and a couple of other minor bugs.
792 - Set DPD defaults in ipsec starter to dpd_delay=30s and dpd_timeout=150s.
794 - The IKEv1 pluto daemon now supports the ESP encryption algorithm CAMELLIA
795 with key lengths of 128, 192, and 256 bits, as well as the authentication
796 algorithm AES_XCBC_MAC. Configuration example: esp=camellia192-aesxcbc.
802 - libstrongswan has been modularized to attach crypto algorithms,
803 credential implementations (keys, certificates) and fetchers dynamically
804 through plugins. Existing code has been ported to plugins:
805 - RSA/Diffie-Hellman implementation using the GNU Multi Precision library
806 - X509 certificate system supporting CRLs, OCSP and attribute certificates
807 - Multiple plugins providing crypto algorithms in software
808 - CURL and OpenLDAP fetcher
810 - libstrongswan gained a relational database API which uses pluggable database
811 providers. Plugins for MySQL and SQLite are available.
813 - The IKEv2 keying daemon charon is more extensible. Generic plugins may provide
814 connection configuration, credentials and EAP methods or control the daemon.
815 Existing code has been ported to plugins:
816 - EAP-AKA, EAP-SIM, EAP-MD5 and EAP-Identity
817 - stroke configuration, credential and control (compatible to pluto)
818 - XML bases management protocol to control and query the daemon
819 The following new plugins are available:
820 - An experimental SQL configuration, credential and logging plugin on
821 top of either MySQL or SQLite
822 - A unit testing plugin to run tests at daemon startup
824 - The authentication and credential framework in charon has been heavily
825 refactored to support modular credential providers, proper
826 CERTREQ/CERT payload exchanges and extensible authorization rules.
828 - The framework of strongSwan Manager has envolved to the web application
829 framework libfast (FastCGI Application Server w/ Templates) and is usable
830 by other applications.
836 - IKE rekeying in NAT situations did not inherit the NAT conditions
837 to the rekeyed IKE_SA so that the UDP encapsulation was lost with
838 the next CHILD_SA rekeying.
840 - Wrong type definition of the next_payload variable in id_payload.c
841 caused an INVALID_SYNTAX error on PowerPC platforms.
843 - Implemented IKEv2 EAP-SIM server and client test modules that use
844 triplets stored in a file. For details on the configuration see
845 the scenario 'ikev2/rw-eap-sim-rsa'.
851 - Fixed error in the ordering of the certinfo_t records in the ocsp cache that
852 caused multiple entries of the same serial number to be created.
854 - Implementation of a simple EAP-MD5 module which provides CHAP
855 authentication. This may be interesting in conjunction with certificate
856 based server authentication, as weak passwords can't be brute forced
857 (in contradiction to traditional IKEv2 PSK).
859 - A complete software based implementation of EAP-AKA, using algorithms
860 specified in 3GPP2 (S.S0055). This implementation does not use an USIM,
861 but reads the secrets from ipsec.secrets. Make sure to read eap_aka.h
864 - Support for vendor specific EAP methods using Expanded EAP types. The
865 interface to EAP modules has been slightly changed, so make sure to
866 check the changes if you're already rolling your own modules.
872 - The default _updown script now dynamically inserts and removes ip6tables
873 firewall rules if leftfirewall=yes is set in IPv6 connections. New IPv6
874 net-net and roadwarrior (PSK/RSA) scenarios for both IKEv1 and IKEV2 were
877 - Implemented RFC4478 repeated authentication to force EAP/Virtual-IP clients
878 to reestablish an IKE_SA within a given timeframe.
880 - strongSwan Manager supports configuration listing, initiation and termination
881 of IKE and CHILD_SAs.
883 - Fixes and improvements to multithreading code.
885 - IKEv2 plugins have been renamed to libcharon-* to avoid naming conflicts.
886 Make sure to remove the old plugins in $libexecdir/ipsec, otherwise they get
893 - Removed recursive pthread mutexes since uClibc doesn't support them.
899 - In NAT traversal situations and multiple queued Quick Modes,
900 those pending connections inserted by auto=start after the
901 port floating from 500 to 4500 were erronously deleted.
903 - Added a "forceencaps" connection parameter to enforce UDP encapsulation
904 to surmount restrictive firewalls. NAT detection payloads are faked to
905 simulate a NAT situation and trick the other peer into NAT mode (IKEv2 only).
907 - Preview of strongSwan Manager, a web based configuration and monitoring
908 application. It uses a new XML control interface to query the IKEv2 daemon
909 (see http://wiki.strongswan.org/wiki/Manager).
911 - Experimental SQLite configuration backend which will provide the configuration
912 interface for strongSwan Manager in future releases.
914 - Further improvements to MOBIKE support.
920 - Since some third party IKEv2 implementations run into
921 problems with strongSwan announcing MOBIKE capability per
922 default, MOBIKE can be disabled on a per-connection-basis
923 using the mobike=no option. Whereas mobike=no disables the
924 sending of the MOBIKE_SUPPORTED notification and the floating
925 to UDP port 4500 with the IKE_AUTH request even if no NAT
926 situation has been detected, strongSwan will still support
927 MOBIKE acting as a responder.
929 - the default ipsec routing table plus its corresponding priority
930 used for inserting source routes has been changed from 100 to 220.
931 It can be configured using the --with-ipsec-routing-table and
932 --with-ipsec-routing-table-prio options.
934 - the --enable-integrity-test configure option tests the
935 integrity of the libstrongswan crypto code during the charon
938 - the --disable-xauth-vid configure option disables the sending
939 of the XAUTH vendor ID. This can be used as a workaround when
940 interoperating with some Windows VPN clients that get into
941 trouble upon reception of an XAUTH VID without eXtended
942 AUTHentication having been configured.
944 - ipsec stroke now supports the rereadsecrets, rereadaacerts,
945 rereadacerts, and listacerts options.
951 - If a DNS lookup failure occurs when resolving right=%<FQDN>
952 or right=<FQDN> combined with rightallowany=yes then the
953 connection is not updated by ipsec starter thus preventing
954 the disruption of an active IPsec connection. Only if the DNS
955 lookup successfully returns with a changed IP address the
956 corresponding connection definition is updated.
958 - Routes installed by the keying daemons are now in a separate
959 routing table with the ID 100 to avoid conflicts with the main
960 table. Route lookup for IKEv2 traffic is done in userspace to ignore
961 routes installed for IPsec, as IKE traffic shouldn't get encapsulated.
967 - The pluto IKEv1 daemon now exhibits the same behaviour as its
968 IKEv2 companion charon by inserting an explicit route via the
969 _updown script only if a sourceip exists. This is admissible
970 since routing through the IPsec tunnel is handled automatically
971 by NETKEY's IPsec policies. As a consequence the left|rightnexthop
972 parameter is not required any more.
974 - The new IKEv1 parameter right|leftallowany parameters helps to handle
975 the case where both peers possess dynamic IP addresses that are
976 usually resolved using DynDNS or a similar service. The configuration
981 can be used by the initiator to start up a connection to a peer
982 by resolving peer.foo.bar into the currently allocated IP address.
983 Thanks to the rightallowany flag the connection behaves later on
988 so that the peer can rekey the connection as an initiator when his
989 IP address changes. An alternative notation is
993 which will implicitly set rightallowany=yes.
995 - ipsec starter now fails more gracefully in the presence of parsing
996 errors. Flawed ca and conn section are discarded and pluto is started
997 if non-fatal errors only were encountered. If right=%peer.foo.bar
998 cannot be resolved by DNS then right=%any will be used so that passive
999 connections as a responder are still possible.
1001 - The new pkcs11initargs parameter that can be placed in the
1002 setup config section of /etc/ipsec.conf allows the definition
1003 of an argument string that is used with the PKCS#11 C_Initialize()
1004 function. This non-standard feature is required by the NSS softoken
1005 library. This patch was contributed by Robert Varga.
1007 - Fixed a bug in ipsec starter introduced by strongswan-2.8.5
1008 which caused a segmentation fault in the presence of unknown
1009 or misspelt keywords in ipsec.conf. This bug fix was contributed
1012 - Partial support for MOBIKE in IKEv2. The initiator acts on interface/
1013 address configuration changes and updates IKE and IPsec SAs dynamically.
1019 - IKEv2 peer configuration selection now can be based on a given
1020 certification authority using the rightca= statement.
1022 - IKEv2 authentication based on RSA signatures now can handle multiple
1023 certificates issued for a given peer ID. This allows a smooth transition
1024 in the case of a peer certificate renewal.
1026 - IKEv2: Support for requesting a specific virtual IP using leftsourceip on the
1027 client and returning requested virtual IPs using rightsourceip=%config
1028 on the server. If the server does not support configuration payloads, the
1029 client enforces its leftsourceip parameter.
1031 - The ./configure options --with-uid/--with-gid allow pluto and charon
1032 to drop their privileges to a minimum and change to an other UID/GID. This
1033 improves the systems security, as a possible intruder may only get the
1034 CAP_NET_ADMIN capability.
1036 - Further modularization of charon: Pluggable control interface and
1037 configuration backend modules provide extensibility. The control interface
1038 for stroke is included, and further interfaces using DBUS (NetworkManager)
1039 or XML are on the way. A backend for storing configurations in the daemon
1040 is provided and more advanced backends (using e.g. a database) are trivial
1043 - Fixed a compilation failure in libfreeswan occuring with Linux kernel
1050 - Support for an additional Diffie-Hellman exchange when creating/rekeying
1051 a CHILD_SA in IKEv2 (PFS). PFS is enabled when the proposal contains a
1052 DH group (e.g. "esp=aes128-sha1-modp1536"). Further, DH group negotiation
1053 is implemented properly for rekeying.
1055 - Support for the AES-XCBC-96 MAC algorithm for IPsec SAs when using IKEv2
1056 (requires linux >= 2.6.20). It is enabled using e.g. "esp=aes256-aesxcbc".
1058 - Working IPv4-in-IPv6 and IPv6-in-IPv4 tunnels for linux >= 2.6.21.
1060 - Added support for EAP modules which do not establish an MSK.
1062 - Removed the dependencies from the /usr/include/linux/ headers by
1063 including xfrm.h, ipsec.h, and pfkeyv2.h in the distribution.
1065 - crlNumber is now listed by ipsec listcrls
1067 - The xauth_modules.verify_secret() function now passes the
1074 - Server side cookie support. If to may IKE_SAs are in CONNECTING state,
1075 cookies are enabled and protect against DoS attacks with faked source
1076 addresses. Number of IKE_SAs in CONNECTING state is also limited per
1077 peer address to avoid resource exhaustion. IKE_SA_INIT messages are
1078 compared to properly detect retransmissions and incoming retransmits are
1079 detected even if the IKE_SA is blocked (e.g. doing OCSP fetches).
1081 - The IKEv2 daemon charon now supports dynamic http- and ldap-based CRL
1082 fetching enabled by crlcheckinterval > 0 and caching fetched CRLs
1083 enabled by cachecrls=yes.
1085 - Added the configuration options --enable-nat-transport which enables
1086 the potentially insecure NAT traversal for IPsec transport mode and
1087 --disable-vendor-id which disables the sending of the strongSwan
1090 - Fixed a long-standing bug in the pluto IKEv1 daemon which caused
1091 a segmentation fault if a malformed payload was detected in the
1092 IKE MR2 message and pluto tried to send an encrypted notification
1095 - Added the NATT_IETF_02_N Vendor ID in order to support IKEv1 connections
1096 with Windows 2003 Server which uses a wrong VID hash.
1102 - Support of SHA2_384 hash function for protecting IKEv1
1103 negotiations and support of SHA2 signatures in X.509 certificates.
1105 - Fixed a serious bug in the computation of the SHA2-512 HMAC
1106 function. Introduced automatic self-test of all IKEv1 hash
1107 and hmac functions during pluto startup. Failure of a self-test
1108 currently issues a warning only but does not exit pluto [yet].
1110 - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2.
1112 - Full support of CA information sections. ipsec listcainfos
1113 now shows all collected crlDistributionPoints and OCSP
1116 - Support of the Online Certificate Status Protocol (OCSP) for IKEv2.
1117 This feature requires the HTTP fetching capabilities of the libcurl
1118 library which must be enabled by setting the --enable-http configure
1121 - Refactored core of the IKEv2 message processing code, allowing better
1122 code reuse and separation.
1124 - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration
1125 payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted
1126 by the requestor and installed in a resolv.conf file.
1128 - The IKEv2 daemon charon installs a route for each IPsec policy to use
1129 the correct source address even if an application does not explicitly
1132 - Integrated the EAP framework into charon which loads pluggable EAP library
1133 modules. The ipsec.conf parameter authby=eap initiates EAP authentication
1134 on the client side, while the "eap" parameter on the server side defines
1135 the EAP method to use for client authentication.
1136 A generic client side EAP-Identity module and an EAP-SIM authentication
1137 module using a third party card reader implementation are included.
1139 - Added client side support for cookies.
1141 - Integrated the fixes done at the IKEv2 interoperability bakeoff, including
1142 strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor
1143 fixes to enhance interoperability with other implementations.
1149 - strongSwan now interoperates with the NCP Secure Entry Client,
1150 the Shrew Soft VPN Client, and the Cisco VPN client, doing both
1151 XAUTH and Mode Config.
1153 - UNITY attributes are now recognized and UNITY_BANNER is set
1154 to a default string.
1160 - IKEv1: Support for extended authentication (XAUTH) in combination
1161 with ISAKMP Main Mode RSA or PSK authentication. Both client and
1162 server side were implemented. Handling of user credentials can
1163 be done by a run-time loadable XAUTH module. By default user
1164 credentials are stored in ipsec.secrets.
1166 - IKEv2: Support for reauthentication when rekeying
1168 - IKEv2: Support for transport mode
1170 - fixed a lot of bugs related to byte order
1172 - various other bugfixes
1178 - IKEv1: Implementation of ModeConfig push mode via the new connection
1179 keyword modeconfig=push allows interoperability with Cisco VPN gateways.
1181 - IKEv1: The command ipsec statusall now shows "DPD active" for all
1182 ISAKMP SAs that are under active Dead Peer Detection control.
1184 - IKEv2: Charon's logging and debugging framework has been completely rewritten.
1185 Instead of logger, special printf() functions are used to directly
1186 print objects like hosts (%H) identifications (%D), certificates (%Q),
1187 etc. The number of debugging levels have been reduced to:
1189 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private)
1191 The debugging levels can either be specified statically in ipsec.conf as
1194 charondebug="lib 1, cfg 3, net 2"
1196 or changed at runtime via stroke as
1198 ipsec stroke loglevel cfg 2
1204 - Implemented full support for IPv6-in-IPv6 tunnels.
1206 - Added configuration options for dead peer detection in IKEv2. dpd_action
1207 types "clear", "hold" and "restart" are supported. The dpd_timeout
1208 value is not used, as the normal retransmission policy applies to
1209 detect dead peers. The dpd_delay parameter enables sending of empty
1210 informational message to detect dead peers in case of inactivity.
1212 - Added support for preshared keys in IKEv2. PSK keys configured in
1213 ipsec.secrets are loaded. The authby parameter specifies the authentication
1214 method to authentificate ourself, the other peer may use PSK or RSA.
1216 - Changed retransmission policy to respect the keyingtries parameter.
1218 - Added private key decryption. PEM keys encrypted with AES-128/192/256
1219 or 3DES are supported.
1221 - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to
1222 encrypt IKE traffic.
1224 - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates
1225 signed with such a hash algorithm.
1227 - Added initial support for updown scripts. The actions up-host/client and
1228 down-host/client are executed. The leftfirewall=yes parameter
1229 uses the default updown script to insert dynamic firewall rules, a custom
1230 updown script may be specified with the leftupdown parameter.
1236 - Added support for the auto=route ipsec.conf parameter and the
1237 ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and
1238 CHILD_SAs dynamically on demand when traffic is detected by the
1241 - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter.
1242 As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only
1243 new keys are generated using perfect forward secrecy. An optional flag
1244 which enforces reauthentication will be implemented later.
1246 - "sha" and "sha1" are now treated as synonyms in the ike= and esp=
1247 algorithm configuration statements.
1253 - Full X.509 certificate trust chain verification has been implemented.
1254 End entity certificates can be exchanged via CERT payloads. The current
1255 default is leftsendcert=always, since CERTREQ payloads are not supported
1256 yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls.
1258 - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2
1259 would offer more possibilities for traffic selection, but the Linux kernel
1260 currently does not support it. That's why we stick with these simple
1261 ipsec.conf rules for now.
1263 - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no
1264 IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear,
1267 - Initial NAT traversal support in IKEv2. Charon includes NAT detection
1268 notify payloads to detect NAT routers between the peers. It switches
1269 to port 4500, uses UDP encapsulated ESP packets, handles peer address
1270 changes gracefully and sends keep alive message periodically.
1272 - Reimplemented IKE_SA state machine for charon, which allows simultaneous
1273 rekeying, more shared code, cleaner design, proper retransmission
1274 and a more extensible code base.
1276 - The mixed PSK/RSA roadwarrior detection capability introduced by the
1277 strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal
1278 payloads by the responder right before any defined IKE Main Mode state had
1279 been established. Although any form of bad proposal syntax was being correctly
1280 detected by the payload parser, the subsequent error handler didn't check
1281 the state pointer before logging current state information, causing an
1282 immediate crash of the pluto keying daemon due to a NULL pointer.
1288 - Added algorithm selection to charon: New default algorithms for
1289 ike=aes128-sha-modp2048, as both daemons support it. The default
1290 for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles
1291 the ike/esp parameter the same way as pluto. As this syntax does
1292 not allow specification of a pseudo random function, the same
1293 algorithm as for integrity is used (currently sha/md5). Supported
1295 Encryption: aes128, aes192, aes256
1296 Integrity/PRF: md5, sha (using hmac)
1297 DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192
1299 Encryption: aes128, aes192, aes256, 3des, blowfish128,
1300 blowfish192, blowfish256
1301 Integrity: md5, sha1
1302 More IKE encryption algorithms will come after porting libcrypto into
1305 - initial support for rekeying CHILD_SAs using IKEv2. Currently no
1306 perfect forward secrecy is used. The rekeying parameters rekey,
1307 rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported
1308 when using IKEv2. WARNING: charon currently is unable to handle
1309 simultaneous rekeying. To avoid such a situation, use a large
1310 rekeyfuzz, or even better, set rekey=no on one peer.
1312 - support for host2host, net2net, host2net (roadwarrior) tunnels
1313 using predefined RSA certificates (see uml scenarios for
1314 configuration examples).
1316 - new build environment featuring autotools. Features such
1317 as HTTP, LDAP and smartcard support may be enabled using
1318 the ./configure script. Changing install directories
1319 is possible, too. See ./configure --help for more details.
1321 - better integration of charon with ipsec starter, which allows
1322 (almost) transparent operation with both daemons. charon
1323 handles ipsec commands up, down, status, statusall, listall,
1324 listcerts and allows proper load, reload and delete of connections
1331 - initial support of the IKEv2 protocol. Connections in
1332 ipsec.conf designated by keyexchange=ikev2 are negotiated
1333 by the new IKEv2 charon keying daemon whereas those marked
1334 by keyexchange=ikev1 or the default keyexchange=ike are
1335 handled thy the IKEv1 pluto keying daemon. Currently only
1336 a limited subset of functions are available with IKEv2
1337 (Default AES encryption, authentication based on locally
1338 imported X.509 certificates, unencrypted private RSA keys
1339 in PKCS#1 file format, limited functionality of the ipsec
1346 - the dynamic iptables rules from the _updown_x509 template
1347 for KLIPS and the _updown_policy template for NETKEY have
1348 been merged into the default _updown script. The existing
1349 left|rightfirewall keyword causes the automatic insertion
1350 and deletion of ACCEPT rules for tunneled traffic upon
1351 the successful setup and teardown of an IPsec SA, respectively.
1352 left|rightfirwall can be used with KLIPS under any Linux 2.4
1353 kernel or with NETKEY under a Linux kernel version >= 2.6.16
1354 in conjuction with iptables >= 1.3.5. For NETKEY under a Linux
1355 kernel version < 2.6.16 which does not support IPsec policy
1356 matching yet, please continue to use a copy of the _updown_espmark
1357 template loaded via the left|rightupdown keyword.
1359 - a new left|righthostaccess keyword has been introduced which
1360 can be used in conjunction with left|rightfirewall and the
1361 default _updown script. By default leftfirewall=yes inserts
1362 a bi-directional iptables FORWARD rule for a local client network
1363 with a netmask different from 255.255.255.255 (single host).
1364 This does not allow to access the VPN gateway host via its
1365 internal network interface which is part of the client subnet
1366 because an iptables INPUT and OUTPUT rule would be required.
1367 lefthostaccess=yes will cause this additional ACCEPT rules to
1370 - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal
1371 payload is preparsed in order to find out whether the roadwarrior
1372 requests PSK or RSA so that a matching connection candidate can
1379 - the new _updown_policy template allows ipsec policy based
1380 iptables firewall rules. Required are iptables version
1381 >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes
1382 the _updown_espmark template, so that no INPUT mangle rules
1383 are required any more.
1385 - added support of DPD restart mode
1387 - ipsec starter now allows the use of wildcards in include
1388 statements as e.g. in "include /etc/my_ipsec/*.conf".
1389 Patch courtesy of Matthias Haas.
1391 - the Netscape OID 'employeeNumber' is now recognized and can be
1392 used as a Relative Distinguished Name in certificates.
1398 - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec
1399 command and not of ipsec setup any more.
1401 - ipsec starter now supports AH authentication in conjunction with
1402 ESP encryption. AH authentication is configured in ipsec.conf
1403 via the auth=ah parameter.
1405 - The command ipsec scencrypt|scdecrypt <args> is now an alias for
1406 ipsec whack --scencrypt|scdecrypt <args>.
1408 - get_sa_info() now determines for the native netkey IPsec stack
1409 the exact time of the last use of an active eroute. This information
1410 is used by the Dead Peer Detection algorithm and is also displayed by
1411 the ipsec status command.
1417 - running under the native Linux 2.6 IPsec stack, the function
1418 get_sa_info() is called by ipsec auto --status to display the current
1419 number of transmitted bytes per IPsec SA.
1421 - get_sa_info() is also used by the Dead Peer Detection process to detect
1422 recent ESP activity. If ESP traffic was received from the peer within
1423 the last dpd_delay interval then no R_Y_THERE notification must be sent.
1425 - strongSwan now supports the Relative Distinguished Name "unstructuredName"
1426 in ID_DER_ASN1_DN identities. The following notations are possible:
1428 rightid="unstructuredName=John Doe"
1429 rightid="UN=John Doe"
1431 - fixed a long-standing bug which caused PSK-based roadwarrior connections
1432 to segfault in the function id.c:same_id() called by keys.c:get_secret()
1433 if an FQDN, USER_FQDN, or Key ID was defined, as in the following example.
1440 - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall).
1442 - ipsec starter didn't set host_addr and client.addr ports in whack msg.
1444 - in order to guarantee backwards-compatibility with the script-based
1445 auto function (e.g. auto --replace), the ipsec starter scripts stores
1446 the defaultroute information in the temporary file /var/run/ipsec.info.
1448 - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH
1449 Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config
1452 - the ipsec starter now also recognizes the parameters authby=never and
1453 type=passthrough|pass|drop|reject.
1459 - ipsec starter now supports the also parameter which allows
1460 a modular structure of the connection definitions. Thus
1461 "ipsec start" is now ready to replace "ipsec setup".
1467 - Mathieu Lafon's popular ipsec starter tool has been added to the
1468 strongSwan distribution. Many thanks go to Stephan Scholz from astaro
1469 for his integration work. ipsec starter is a C program which is going
1470 to replace the various shell and awk starter scripts (setup, _plutoload,
1471 _plutostart, _realsetup, _startklips, _confread, and auto). Since
1472 ipsec.conf is now parsed only once, the starting of multiple tunnels is
1473 accelerated tremedously.
1475 - Added support of %defaultroute to the ipsec starter. If the IP address
1476 changes, a HUP signal to the ipsec starter will automatically
1477 reload pluto's connections.
1479 - moved most compile time configurations from pluto/Makefile to
1480 Makefile.inc by defining the options USE_LIBCURL, USE_LDAP,
1481 USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE.
1483 - removed the ipsec verify and ipsec newhostkey commands
1485 - fixed some 64-bit issues in formatted print statements
1487 - The scepclient functionality implementing the Simple Certificate
1488 Enrollment Protocol (SCEP) is nearly complete but hasn't been
1495 - CA certicates are now automatically loaded from a smartcard
1496 or USB crypto token and appear in the ipsec auto --listcacerts
1503 - when using "ipsec whack --scencrypt <data>" with a PKCS#11
1504 library that does not support the C_Encrypt() Cryptoki
1505 function (e.g. OpenSC), the RSA encryption is done in
1506 software using the public key fetched from the smartcard.
1508 - The scepclient function now allows to define the
1509 validity of a self-signed certificate using the --days,
1510 --startdate, and --enddate options. The default validity
1511 has been changed from one year to five years.
1517 - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11
1518 interface to other applications for RSA encryption and decryption
1519 via the whack interface. Notation:
1521 ipsec whack --scencrypt <data>
1522 [--inbase 16|hex|64|base64|256|text|ascii]
1523 [--outbase 16|hex|64|base64|256|text|ascii]
1526 ipsec whack --scdecrypt <data>
1527 [--inbase 16|hex|64|base64|256|text|ascii]
1528 [--outbase 16|hex|64|base64|256|text|ascii]
1531 The default setting for inbase and outbase is hex.
1533 The new proxy interface can be used for securing symmetric
1534 encryption keys required by the cryptoloop or dm-crypt
1535 disk encryption schemes, especially in the case when
1536 pkcs11keepstate=yes causes pluto to lock the pkcs11 slot
1539 - if the file /etc/ipsec.secrets is lacking during the startup of
1540 pluto then the root-readable file /etc/ipsec.d/private/myKey.der
1541 containing a 2048 bit RSA private key and a matching self-signed
1542 certificate stored in the file /etc/ipsec.d/certs/selfCert.der
1543 is automatically generated by calling the function
1545 ipsec scepclient --out pkcs1 --out cert-self
1547 scepclient was written by Jan Hutter and Martin Willi, students
1548 at the University of Applied Sciences in Rapperswil, Switzerland.
1554 - the current extension of the PKCS#7 framework introduced
1555 a parsing error in PKCS#7 wrapped X.509 certificates that are
1556 e.g. transmitted by Windows XP when multi-level CAs are used.
1557 the parsing syntax has been fixed.
1559 - added a patch by Gerald Richter which tolerates multiple occurrences
1560 of the ipsec0 interface when using KLIPS.
1566 - with gawk-3.1.4 the word "default2 has become a protected
1567 keyword for use in switch statements and cannot be used any
1568 more in the strongSwan scripts. This problem has been
1569 solved by renaming "default" to "defaults" and "setdefault"
1570 in the scripts _confread and auto, respectively.
1572 - introduced the parameter leftsendcert with the values
1574 always|yes (the default, always send a cert)
1575 ifasked (send the cert only upon a cert request)
1576 never|no (never send a cert, used for raw RSA keys and
1579 - fixed the initialization of the ESP key length to a default of
1580 128 bits in the case that the peer does not send a key length
1581 attribute for AES encryption.
1583 - applied Herbert Xu's uniqueIDs patch
1585 - applied Herbert Xu's CLOEXEC patches
1591 - CRLs can now be cached also in the case when the issuer's
1592 certificate does not contain a subjectKeyIdentifier field.
1593 In that case the subjectKeyIdentifier is computed by pluto as the
1594 160 bit SHA-1 hash of the issuer's public key in compliance
1595 with section 4.2.1.2 of RFC 3280.
1597 - Fixed a bug introduced by strongswan-2.5.1 which eliminated
1598 not only multiple Quick Modes of a given connection but also
1599 multiple connections between two security gateways.
1605 - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute
1606 installed either by setting auto=route in ipsec.conf or by
1607 a connection put into hold, generates an XFRM_AQUIRE event
1608 for each packet that wants to use the not-yet exisiting
1609 tunnel. Up to now each XFRM_AQUIRE event led to an entry in
1610 the Quick Mode queue, causing multiple IPsec SA to be
1611 established in rapid succession. Starting with strongswan-2.5.1
1612 only a single IPsec SA is established per host-pair connection.
1614 - Right after loading the PKCS#11 module, all smartcard slots are
1615 searched for certificates. The result can be viewed using
1618 ipsec auto --listcards
1620 The certificate objects found in the slots are numbered
1621 starting with #1, #2, etc. This position number can be used to address
1622 certificates (leftcert=%smartcard) and keys (: PIN %smartcard)
1623 in ipsec.conf and ipsec.secrets, respectively:
1625 %smartcard (selects object #1)
1626 %smartcard#1 (selects object #1)
1627 %smartcard#3 (selects object #3)
1629 As an alternative the existing retrieval scheme can be used:
1631 %smartcard:45 (selects object with id=45)
1632 %smartcard0 (selects first object in slot 0)
1633 %smartcard4:45 (selects object in slot 4 with id=45)
1635 - Depending on the settings of CKA_SIGN and CKA_DECRYPT
1636 private key flags either C_Sign() or C_Decrypt() is used
1637 to generate a signature.
1639 - The output buffer length parameter siglen in C_Sign()
1640 is now initialized to the actual size of the output
1641 buffer prior to the function call. This fixes the
1642 CKR_BUFFER_TOO_SMALL error that could occur when using
1643 the OpenSC PKCS#11 module.
1645 - Changed the initialization of the PKCS#11 CK_MECHANISM in
1646 C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }.
1648 - Refactored the RSA public/private key code and transferred it
1649 from keys.c to the new pkcs1.c file as a preparatory step
1650 towards the release of the SCEP client.
1656 - The loading of a PKCS#11 smartcard library module during
1657 runtime does not require OpenSC library functions any more
1658 because the corresponding code has been integrated into
1659 smartcard.c. Also the RSAREF pkcs11 header files have been
1660 included in a newly created pluto/rsaref directory so that
1661 no external include path has to be defined any longer.
1663 - A long-awaited feature has been implemented at last:
1664 The local caching of CRLs fetched via HTTP or LDAP, activated
1665 by the parameter cachecrls=yes in the config setup section
1666 of ipsec.conf. The dynamically fetched CRLs are stored under
1667 a unique file name containing the issuer's subjectKeyID
1668 in /etc/ipsec.d/crls.
1670 - Applied a one-line patch courtesy of Michael Richardson
1671 from the Openswan project which fixes the kernel-oops
1672 in KLIPS when an snmp daemon is running on the same box.
1678 - Eliminated null length CRL distribution point strings.
1680 - Fixed a trust path evaluation bug introduced with 2.4.3
1686 - Improved the joint OCSP / CRL revocation policy.
1687 OCSP responses have precedence over CRL entries.
1689 - Introduced support of CRLv2 reason codes.
1691 - Fixed a bug with key-pad equipped readers which caused
1692 pluto to prompt for the pin via the console when the first
1693 occasion to enter the pin via the key-pad was missed.
1695 - When pluto is built with LDAP_V3 enabled, the library
1696 liblber required by newer versions of openldap is now
1703 - Added the _updown_espmark template which requires all
1704 incoming ESP traffic to be marked with a default mark
1707 - Introduced the pkcs11keepstate parameter in the config setup
1708 section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11
1709 session and login states are kept as long as possible during
1710 the lifetime of pluto. This means that a PIN entry via a key
1711 pad has to be done only once.
1713 - Introduced the pkcs11module parameter in the config setup
1714 section of ipsec.conf which specifies the PKCS#11 module
1715 to be used with smart cards. Example:
1717 pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo
1719 - Added support of smartcard readers equipped with a PIN pad.
1721 - Added patch by Jay Pfeifer which detects when netkey
1722 modules have been statically built into the Linux 2.6 kernel.
1724 - Added two patches by Herbert Xu. The first uses ip xfrm
1725 instead of setkey to flush the IPsec policy database. The
1726 second sets the optional flag in inbound IPComp SAs only.
1728 - Applied Ulrich Weber's patch which fixes an interoperability
1729 problem between native IPsec and KLIPS systems caused by
1730 setting the replay window to 32 instead of 0 for ipcomp.
1736 - Fixed a bug which caused an unwanted Mode Config request
1737 to be initiated in the case where "right" was used to denote
1738 the local side in ipsec.conf and "left" the remote side,
1739 contrary to the recommendation that "right" be remote and
1746 - updated Vendor ID to strongSwan-2.4.0
1748 - updated copyright statement to include David Buechi and
1755 - strongSwan now communicates with attached smartcards and
1756 USB crypto tokens via the standardized PKCS #11 interface.
1757 By default the OpenSC library from www.opensc.org is used
1758 but any other PKCS#11 library could be dynamically linked.
1759 strongSwan's PKCS#11 API was implemented by David Buechi
1760 and Michael Meier, both graduates of the Zurich University
1761 of Applied Sciences in Winterthur, Switzerland.
1763 - When a %trap eroute is triggered by an outgoing IP packet
1764 then the native IPsec stack of the Linux 2.6 kernel [often/
1765 always?] returns an XFRM_ACQUIRE message with an undefined
1766 protocol family field and the connection setup fails.
1767 As a workaround IPv4 (AF_INET) is now assumed.
1769 - the results of the UML test scenarios are now enhanced
1770 with block diagrams of the virtual network topology used
1771 in a particular test.
1777 - fixed IV used to decrypt informational messages.
1778 This bug was introduced with Mode Config functionality.
1780 - fixed NCP Vendor ID.
1782 - undid one of Ulrich Weber's maximum udp size patches
1783 because it caused a segmentation fault with NAT-ed
1786 - added UML scenarios wildcards and attr-cert which
1787 demonstrate the implementation of IPsec policies based
1788 on wildcard parameters contained in Distinguished Names and
1789 on X.509 attribute certificates, respectively.
1795 - Added basic Mode Config functionality
1797 - Added Mathieu Lafon's patch which upgrades the status of
1798 the NAT-Traversal implementation to RFC 3947.
1800 - The _startklips script now also loads the xfrm4_tunnel
1803 - Added Ulrich Weber's netlink replay window size and
1804 maximum udp size patches.
1806 - UML testing now uses the Linux 2.6.10 UML kernel by default.
1812 - Eric Marchionni and Patrik Rayo, both recent graduates from
1813 the Zuercher Hochschule Winterthur in Switzerland, created a
1814 User-Mode-Linux test setup for strongSwan. For more details
1815 please read the INSTALL and README documents in the testing
1818 - Full support of group attributes based on X.509 attribute
1819 certificates. Attribute certificates can be generated
1820 using the openac facility. For more details see
1824 The group attributes can be used in connection definitions
1825 in order to give IPsec access to specific user groups.
1826 This is done with the new parameter left|rightgroups as in
1828 rightgroups="Research, Sales"
1830 giving access to users possessing the group attributes
1831 Research or Sales, only.
1833 - In Quick Mode clients with subnet mask /32 are now
1834 coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should
1835 fix rekeying problems with the SafeNet/SoftRemote and NCP
1836 Secure Entry Clients.
1838 - Changed the defaults of the ikelifetime and keylife parameters
1839 to 3h and 1h, respectively. The maximum allowable values are
1840 now both set to 24 h.
1842 - Suppressed notification wars between two IPsec peers that
1843 could e.g. be triggered by incorrect ISAKMP encryption.
1845 - Public RSA keys can now have identical IDs if either the
1846 issuing CA or the serial number is different. The serial
1847 number of a certificate is now shown by the command
1849 ipsec auto --listpubkeys
1855 - Added Tuomo Soini's sourceip feature which allows a strongSwan
1856 roadwarrior to use a fixed Virtual IP (see README section 2.6)
1857 and reduces the well-known four tunnel case on VPN gateways to
1858 a single tunnel definition (see README section 2.4).
1860 - Fixed a bug occuring with NAT-Traversal enabled when the responder
1861 suddenly turns initiator and the initiator cannot find a matching
1862 connection because of the floated IKE port 4500.
1864 - Removed misleading ipsec verify command from barf.
1866 - Running under the native IP stack, ipsec --version now shows
1867 the Linux kernel version (courtesy to the Openswan project).
1873 - Introduced the ipsec auto --listalgs monitoring command which lists
1874 all currently registered IKE and ESP algorithms.
1876 - Fixed a bug in the ESP algorithm selection occuring when the strict flag
1877 is set and the first proposed transform does not match.
1879 - Fixed another deadlock in the use of the lock_certs_and_keys() mutex,
1880 occuring when a smartcard is present.
1882 - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event.
1884 - Fixed the printing of the notification names (null)
1886 - Applied another of Herbert Xu's Netlink patches.
1892 - Support of Dead Peer Detection. The connection parameter
1894 dpdaction=clear|hold
1896 activates DPD for the given connection.
1898 - The default Opportunistic Encryption (OE) policy groups are not
1899 automatically included anymore. Those wishing to activate OE can include
1900 the policy group with the following statement in ipsec.conf:
1902 include /etc/ipsec.d/examples/oe.conf
1904 The default for [right|left]rsasigkey is now set to %cert.
1906 - strongSwan now has a Vendor ID of its own which can be activated
1907 using the compile option VENDORID
1909 - Applied Herbert Xu's patch which sets the compression algorithm correctly.
1911 - Applied Herbert Xu's patch fixing an ESPINUDP problem
1913 - Applied Herbert Xu's patch setting source/destination port numbers.
1915 - Reapplied one of Herbert Xu's NAT-Traversal patches which got
1916 lost during the migration from SuperFreeS/WAN.
1918 - Fixed a deadlock in the use of the lock_certs_and_keys() mutex.
1920 - Fixed the unsharing of alg parameters when instantiating group
1927 - Thomas Walpuski made me aware of a potential DoS attack via
1928 a PKCS#7-wrapped certificate bundle which could overwrite valid CA
1929 certificates in Pluto's authority certificate store. This vulnerability
1930 was fixed by establishing trust in CA candidate certificates up to a
1931 trusted root CA prior to insertion into Pluto's chained list.
1933 - replaced the --assign option by the -v option in the auto awk script
1934 in order to make it run with mawk under debian/woody.
1940 - Split of the status information between ipsec auto --status (concise)
1941 and ipsec auto --statusall (verbose). Both commands can be used with
1942 an optional connection selector:
1944 ipsec auto --status[all] <connection_name>
1946 - Added the description of X.509 related features to the ipsec_auto(8)
1949 - Hardened the ASN.1 parser in debug mode, especially the printing
1950 of malformed distinguished names.
1952 - The size of an RSA public key received in a certificate is now restricted to
1954 512 bits <= modulus length <= 8192 bits.
1956 - Fixed the debug mode enumeration.
1962 - Fixed another PKCS#7 vulnerability which could lead to an
1963 endless loop while following the X.509 trust chain.
1969 - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski
1970 that accepted end certificates having identical issuer and subject
1971 distinguished names in a multi-tier X.509 trust chain.
1977 - Removed all remaining references to ipsec_netlink.h in KLIPS.
1983 - The new "ca" section allows to define the following parameters:
1986 cacert=koolCA.pem # cacert of kool CA
1987 ocspuri=http://ocsp.kool.net:8001 # ocsp server
1988 ldapserver=ldap.kool.net # default ldap server
1989 crluri=http://www.kool.net/kool.crl # crl distribution point
1990 crluri2="ldap:///O=Kool, C= .." # crl distribution point #2
1991 auto=add # add, ignore
1993 The ca definitions can be monitored via the command
1995 ipsec auto --listcainfos
1997 - Fixed cosmetic corruption of /proc filesystem by integrating
1998 D. Hugh Redelmeier's freeswan-2.06 kernel fixes.
2004 - Added support for the 818043 NAT-Traversal update of Microsoft's
2005 Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode.
2007 - A symbolic link to libcrypto is now added in the kernel sources
2008 during kernel compilation
2010 - Fixed a couple of 64 bit issues (mostly casts to int).
2011 Thanks to Ken Bantoft who checked my sources on a 64 bit platform.
2013 - Replaced s[n]printf() statements in the kernel by ipsec_snprintf().
2014 Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro
2015 of the FreeS/WAN team who solved this problem with the 2.4.25 kernel.
2021 - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName
2022 certificate extension which contains no generalName item) can cause
2023 a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has
2024 been hardened to make it more robust against malformed ASN.1 objects.
2026 - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native
2027 Linux 2.6 IPsec stack.
2033 - based on freeswan-2.04, x509-1.5.3, nat-0.6c, alg-0.8.1rc12
