| | 1 | strongswan-4.5.3 |
| | 2 | ---------------- |
| | 3 | |
| | 4 | - IKEv2 charon daemon supports start PASS and DROP shunt policies |
| | 5 | preventing traffic to go through IPsec connections. |
| | 6 | |
| | 7 | - IMC/IMV test pair implementing the RFC 5792 PA-TNC (IF-M) protocol. |
| | 8 | (--enable-imc-test/--enable-imv-test). |
| | 9 | |
| | 10 | - The IKEv2 close action does not use the same value as the ipsec.conf dpdaction |
| | 11 | setting, but the value defined by its own closeaction keyword. The action |
| | 12 | is triggered if the remote peer closes a CHILD_SA unexpectedly. |
| | 13 | |
| | 14 | strongswan-4.5.2 |
| | 15 | ---------------- |
| | 16 | |
| | 17 | - The whitelist plugin for the IKEv2 daemon maintains an in-memory identity |
| | 18 | whitelist. Any connection attempt of peers not whitelisted will get rejected. |
| | 19 | The 'ipsec whitelist' utility provides a simple command line frontend for |
| | 20 | whitelist administration. |
| | 21 | |
| | 22 | - The duplicheck plugin provides a specialized form of duplicate checking, |
| | 23 | doing a liveness check on the old SA and optionally notify a third party |
| | 24 | application about detected duplicates. |
| | 25 | |
| | 26 | - The coupling plugin permanently couples two or more devices by limiting |
| | 27 | authentication to previously used certificates. |
| | 28 | |
| | 29 | - In the case that the peer config and child config don't have the same name |
| | 30 | (usually in SQL database defined connections), ipsec up|route <peer config> |
| | 31 | starts|routes all associated child configs and ipsec up|route <child config> |
| | 32 | only starts|routes the specific child config. |
| | 33 | |
| | 34 | - fixed the encoding and parsing of X.509 certificate policy statements (CPS). |
| | 35 | |
| | 36 | - Duncan Salerno contributed the eap-sim-pcsc plugin implementing a |
| | 37 | pcsc-lite based SIM card backend. |
| | 38 | |
| | 39 | - The eap-peap plugin implements the EAP PEAP protocol. Interoperates |
| | 40 | successfully with a FreeRADIUS server and Windows 7 Agile VPN clients. |
| | 41 | |
| | 42 | - The IKEv2 daemon charon rereads strongswan.conf on SIGHUP and instructs |
| | 43 | all plugins to reload. Currently only the eap-radius and the attr plugins |
| | 44 | support configuration reloading. |
| | 45 | |
| | 46 | - Added userland support to the IKEv2 daemon for Extended Sequence Numbers |
| | 47 | support coming with Linux 2.6.39. To enable ESN on a connection, add |
| | 48 | the 'esn' keyword to the proposal. The default proposal uses 32-bit sequence |
| | 49 | numbers only ('noesn'), and the same value is used if no ESN mode is |
| | 50 | specified. To negotiate ESN support with the peer, include both, e.g. |
| | 51 | esp=aes128-sha1-esn-noesn. |
| | 52 | |
| | 53 | - In addition to ESN, Linux 2.6.39 gained support for replay windows larger |
| | 54 | than 32 packets. The new global strongswan.conf option 'charon.replay_window' |
| | 55 | configures the size of the replay window, in packets. |
| | 56 | |
| | 57 | |
| | 58 | strongswan-4.5.1 |
| | 59 | ---------------- |
| | 60 | |
| | 61 | - Sansar Choinyambuu implemented the RFC 5793 Posture Broker Protocol (BP) |
| | 62 | compatible with Trusted Network Connect (TNC). The TNCCS 2.0 protocol |
| | 63 | requires the tnccs_20, tnc_imc and tnc_imv plugins but does not depend |
| | 64 | on the libtnc library. Any available IMV/IMC pairs conforming to the |
| | 65 | Trusted Computing Group's TNC-IF-IMV/IMC 1.2 interface specification |
| | 66 | can be loaded via /etc/tnc_config. |
| | 67 | |
| | 68 | - Re-implemented the TNCCS 1.1 protocol by using the tnc_imc and tnc_imv |
| | 69 | in place of the external libtnc library. |
| | 70 | |
| | 71 | - The tnccs_dynamic plugin loaded on a TNC server in addition to the |
| | 72 | tnccs_11 and tnccs_20 plugins, dynamically detects the IF-TNCCS |
| | 73 | protocol version used by a TNC client and invokes an instance of |
| | 74 | the corresponding protocol stack. |
| | 75 | |
| | 76 | - IKE and ESP proposals can now be stored in an SQL database using a |
| | 77 | new proposals table. The start_action field in the child_configs |
| | 78 | tables allows the automatic starting or routing of connections stored |
| | 79 | in an SQL database. |
| | 80 | |
| | 81 | - The new certificate_authorities and certificate_distribution_points |
| | 82 | tables make it possible to store CRL and OCSP Certificate Distribution |
| | 83 | points in an SQL database. |
| | 84 | |
| | 85 | - The new 'include' statement allows to recursively include other files in |
| | 86 | strongswan.conf. Existing sections and values are thereby extended and |
| | 87 | replaced, respectively. |
| | 88 | |
| | 89 | - Due to the changes in the parser for strongswan.conf, the configuration |
| | 90 | syntax for the attr plugin has changed. Previously, it was possible to |
| | 91 | specify multiple values of a specific attribute type by adding multiple |
| | 92 | key/value pairs with the same key (e.g. dns) to the plugins.attr section. |
| | 93 | Because values with the same key now replace previously defined values |
| | 94 | this is not possible anymore. As an alternative, multiple values can be |
| | 95 | specified by separating them with a comma (e.g. dns = 1.2.3.4, 2.3.4.5). |
| | 96 | |
| | 97 | - ipsec listalgs now appends (set in square brackets) to each crypto |
| | 98 | algorithm listed the plugin that registered the function. |
| | 99 | |
| | 100 | - Traffic Flow Confidentiality padding supported with Linux 2.6.38 can be used |
| | 101 | by the IKEv2 daemon. The ipsec.conf 'tfc' keyword pads all packets to a given |
| | 102 | boundary, the special value '%mtu' pads all packets to the path MTU. |
| | 103 | |
| | 104 | - The new af-alg plugin can use various crypto primitives of the Linux Crypto |
| | 105 | API using the AF_ALG interface introduced with 2.6.38. This removes the need |
| | 106 | for additional userland implementations of symmetric cipher, hash, hmac and |
| | 107 | xcbc algorithms. |
| | 108 | |
| | 109 | - The IKEv2 daemon supports the INITIAL_CONTACT notify as initiator and |
| | 110 | responder. The notify is sent when initiating configurations with a unique |
| | 111 | policy, set in ipsec.conf via the global 'uniqueids' option. |
| | 112 | |
| | 113 | - The conftest conformance testing framework enables the IKEv2 stack to perform |
| | 114 | many tests using a distinct tool and configuration frontend. Various hooks |
| | 115 | can alter reserved bits, flags, add custom notifies and proposals, reorder |
| | 116 | or drop messages and much more. It is enabled using the --enable-conftest |
| | 117 | ./configure switch. |
| | 118 | |
| | 119 | - The new libstrongswan constraints plugin provides advanced X.509 constraint |
| | 120 | checking. In additon to X.509 pathLen constraints, the plugin checks for |
| | 121 | nameConstraints and certificatePolicies, including policyMappings and |
| | 122 | policyConstraints. The x509 certificate plugin and the pki tool have been |
| | 123 | enhanced to support these extensions. The new left/rightcertpolicy ipsec.conf |
| | 124 | connection keywords take OIDs a peer certificate must have. |
| | 125 | |
| | 126 | - The left/rightauth ipsec.conf keywords accept values with a minimum strength |
| | 127 | for trustchain public keys in bits, such as rsa-2048 or ecdsa-256. |
| | 128 | |
| | 129 | - The revocation and x509 libstrongswan plugins and the pki tool gained basic |
| | 130 | support for delta CRLs. |
| | 131 | |
| | 132 | |
| | 133 | strongswan-4.5.0 |
| | 134 | ---------------- |
| | 135 | |
| | 136 | - IMPORTANT: the default keyexchange mode 'ike' is changing with release 4.5 |
| | 137 | from 'ikev1' to 'ikev2', thus commemorating the five year anniversary of the |
| | 138 | IKEv2 RFC 4306 and its mature successor RFC 5996. The time has definitively |
| | 139 | come for IKEv1 to go into retirement and to cede its place to the much more |
| | 140 | robust, powerful and versatile IKEv2 protocol! |
| | 141 | |
| | 142 | - Added new ctr, ccm and gcm plugins providing Counter, Counter with CBC-MAC |
| | 143 | and Galois/Counter Modes based on existing CBC implementations. These |
| | 144 | new plugins bring support for AES and Camellia Counter and CCM algorithms |
| | 145 | and the AES GCM algorithms for use in IKEv2. |
| | 146 | |
| | 147 | - The new pkcs11 plugin brings full Smartcard support to the IKEv2 daemon and |
| | 148 | the pki utility using one or more PKCS#11 libraries. It currently supports |
| | 149 | RSA private and public key operations and loads X.509 certificates from |
| | 150 | tokens. |
| | 151 | |
| | 152 | - Implemented a general purpose TLS stack based on crypto and credential |
| | 153 | primitives of libstrongswan. libtls supports TLS versions 1.0, 1.1 and 1.2, |
| | 154 | ECDHE-ECDSA/RSA, DHE-RSA and RSA key exchange algorithms and RSA/ECDSA based |
| | 155 | client authentication. |
| | 156 | |
| | 157 | - Based on libtls, the eap-tls plugin brings certificate based EAP |
| | 158 | authentication for client and server. It is compatible to Windows 7 IKEv2 |
| | 159 | Smartcard authentication and the OpenSSL based FreeRADIUS EAP-TLS backend. |
| | 160 | |
| | 161 | - Implemented the TNCCS 1.1 Trusted Network Connect protocol using the |
| | 162 | libtnc library on the strongSwan client and server side via the tnccs_11 |
| | 163 | plugin and optionally connecting to a TNC@FHH-enhanced FreeRADIUS AAA server. |
| | 164 | Depending on the resulting TNC Recommendation, strongSwan clients are granted |
| | 165 | access to a network behind a strongSwan gateway (allow), are put into a |
| | 166 | remediation zone (isolate) or are blocked (none), respectively. Any number |
| | 167 | of Integrity Measurement Collector/Verifier pairs can be attached |
| | 168 | via the tnc-imc and tnc-imv charon plugins. |
| | 169 | |
| | 170 | - The IKEv1 daemon pluto now uses the same kernel interfaces as the IKEv2 |
| | 171 | daemon charon. As a result of this, pluto now supports xfrm marks which |
| | 172 | were introduced in charon with 4.4.1. |
| | 173 | |
| | 174 | - Applets for Maemo 5 (Nokia) allow to easily configure and control IKEv2 |
| | 175 | based VPN connections with EAP authentication on supported devices. |
| | 176 | |
| | 177 | - The RADIUS plugin eap-radius now supports multiple RADIUS servers for |
| | 178 | redundant setups. Servers are selected by a defined priority, server load and |
| | 179 | availability. |
| | 180 | |
| | 181 | - The simple led plugin controls hardware LEDs through the Linux LED subsystem. |
| | 182 | It currently shows activity of the IKE daemon and is a good example how to |
| | 183 | implement a simple event listener. |
| | 184 | |
| | 185 | - Improved MOBIKE behavior in several corner cases, for instance, if the |
| | 186 | initial responder moves to a different address. |
| | 187 | |
| | 188 | - Fixed left-/rightnexthop option, which was broken since 4.4.0. |
| | 189 | |
| | 190 | - Fixed a bug not releasing a virtual IP address to a pool if the XAUTH |
| | 191 | identity was different from the IKE identity. |
| | 192 | |
| | 193 | - Fixed the alignment of ModeConfig messages on 4-byte boundaries in the |
| | 194 | case where the attributes are not a multiple of 4 bytes (e.g. Cisco's |
| | 195 | UNITY_BANNER). |
| | 196 | |
| | 197 | - Fixed the interoperability of the socket_raw and socket_default |
| | 198 | charon plugins. |
| | 199 | |
| | 200 | - Added man page for strongswan.conf |
| | 201 | |
| | 202 | |
| | 203 | strongswan-4.4.1 |
| | 204 | ---------------- |
| | 205 | |
| | 206 | - Support of xfrm marks in IPsec SAs and IPsec policies introduced |
| | 207 | with the Linux 2.6.34 kernel. For details see the example scenarios |
| | 208 | ikev2/nat-two-rw-mark, ikev2/rw-nat-mark-in-out and ikev2/net2net-psk-dscp. |
| | 209 | |
| | 210 | - The PLUTO_MARK_IN and PLUTO_ESP_ENC environment variables can be used |
| | 211 | in a user-specific updown script to set marks on inbound ESP or |
| | 212 | ESP_IN_UDP packets. |
| | 213 | |
| | 214 | - The openssl plugin now supports X.509 certificate and CRL functions. |
| | 215 | |
| | 216 | - OCSP/CRL checking in IKEv2 has been moved to the revocation plugin, enabled |
| | 217 | by default. Plase update manual load directives in strongswan.conf. |
| | 218 | |
| | 219 | - RFC3779 ipAddrBlock constraint checking has been moved to the addrblock |
| | 220 | plugin, disabled by default. Enable it and update manual load directives |
| | 221 | in strongswan.conf, if required. |
| | 222 | |
| | 223 | - The pki utility supports CRL generation using the --signcrl command. |
| | 224 | |
| | 225 | - The ipsec pki --self, --issue and --req commands now support output in |
| | 226 | PEM format using the --outform pem option. |
| | 227 | |
| | 228 | - The major refactoring of the IKEv1 Mode Config functionality now allows |
| | 229 | the transport and handling of any Mode Config attribute. |
| | 230 | |
| | 231 | - The RADIUS proxy plugin eap-radius now supports multiple servers. Configured |
| | 232 | servers are chosen randomly, with the option to prefer a specific server. |
| | 233 | Non-responding servers are degraded by the selection process. |
| | 234 | |
| | 235 | - The ipsec pool tool manages arbitrary configuration attributes stored |
| | 236 | in an SQL database. ipsec pool --help gives the details. |
| | 237 | |
| | 238 | - The new eap-simaka-sql plugin acts as a backend for EAP-SIM and EAP-AKA, |
| | 239 | reading triplets/quintuplets from an SQL database. |
| | 240 | |
| | 241 | - The High Availability plugin now supports a HA enabled in-memory address |
| | 242 | pool and Node reintegration without IKE_SA rekeying. The latter allows |
| | 243 | clients without IKE_SA rekeying support to keep connected during |
| | 244 | reintegration. Additionally, many other issues have been fixed in the ha |
| | 245 | plugin. |
| | 246 | |
| | 247 | - Fixed a potential remote code execution vulnerability resulting from |
| | 248 | the misuse of snprintf(). The vulnerability is exploitable by |
| | 249 | unauthenticated users. |
| | 250 | |
| | 251 | |
| | 252 | strongswan-4.4.0 |
| | 253 | ---------------- |
| | 254 | |
| | 255 | - The IKEv2 High Availability plugin has been integrated. It provides |
| | 256 | load sharing and failover capabilities in a cluster of currently two nodes, |
| | 257 | based on an extend ClusterIP kernel module. More information is available at |
| | 258 | http://wiki.strongswan.org/projects/strongswan/wiki/HighAvailability. |
| | 259 | The development of the High Availability functionality was sponsored by |
| | 260 | secunet Security Networks AG. |
| | 261 | |
| | 262 | - Added IKEv1 and IKEv2 configuration support for the AES-GMAC |
| | 263 | authentication-only ESP cipher. Our aes_gmac kernel patch or a Linux |
| | 264 | 2.6.34 kernel is required to make AES-GMAC available via the XFRM |
| | 265 | kernel interface. |
| | 266 | |
| | 267 | - Added support for Diffie-Hellman groups 22, 23 and 24 to the gmp, gcrypt |
| | 268 | and openssl plugins, usable by both pluto and charon. The new proposal |
| | 269 | keywords are modp1024s160, modp2048s224 and modp2048s256. Thanks to Joy Latten |
| | 270 | from IBM for his contribution. |
| | 271 | |
| | 272 | - The IKEv1 pluto daemon supports RAM-based virtual IP pools using |
| | 273 | the rightsourceip directive with a subnet from which addresses |
| | 274 | are allocated. |
| | 275 | |
| | 276 | - The ipsec pki --gen and --pub commands now allow the output of |
| | 277 | private and public keys in PEM format using the --outform pem |
| | 278 | command line option. |
| | 279 | |
| | 280 | - The new DHCP plugin queries virtual IP addresses for clients from a DHCP |
| | 281 | server using broadcasts, or a defined server using the |
| | 282 | charon.plugins.dhcp.server strongswan.conf option. DNS/WINS server information |
| | 283 | is additionally served to clients if the DHCP server provides such |
| | 284 | information. The plugin is used in ipsec.conf configurations having |
| | 285 | rightsourceip set to %dhcp. |
| | 286 | |
| | 287 | - A new plugin called farp fakes ARP responses for virtual IP addresses |
| | 288 | handed out to clients from the IKEv2 daemon charon. The plugin lets a |
| | 289 | road-warrior act as a client on the local LAN if it uses a virtual IP |
| | 290 | from the responders subnet, e.g. acquired using the DHCP plugin. |
| | 291 | |
| | 292 | - The existing IKEv2 socket implementations have been migrated to the |
| | 293 | socket-default and the socket-raw plugins. The new socket-dynamic plugin |
| | 294 | binds sockets dynamically to ports configured via the left-/rightikeport |
| | 295 | ipsec.conf connection parameters. |
| | 296 | |
| | 297 | - The android charon plugin stores received DNS server information as "net.dns" |
| | 298 | system properties, as used by the Android platform. |
| | 299 | |
| | 300 | |
| | 301 | strongswan-4.3.6 |
| | 302 | ---------------- |
| | 303 | |
| | 304 | - The IKEv2 daemon supports RFC 3779 IP address block constraints |
| | 305 | carried as a critical X.509v3 extension in the peer certificate. |
| | 306 | |
| | 307 | - The ipsec pool --add|del dns|nbns command manages DNS and NBNS name |
| | 308 | server entries that are sent via the IKEv1 Mode Config or IKEv2 |
| | 309 | Configuration Payload to remote clients. |
| | 310 | |
| | 311 | - The Camellia cipher can be used as an IKEv1 encryption algorithm. |
| | 312 | |
| | 313 | - The IKEv1 and IKEV2 daemons now check certificate path length constraints. |
| | 314 | |
| | 315 | - The new ipsec.conf conn option "inactivity" closes a CHILD_SA if no traffic |
| | 316 | was sent or received within the given interval. To close the complete IKE_SA |
| | 317 | if its only CHILD_SA was inactive, set the global strongswan.conf option |
| | 318 | "charon.inactivity_close_ike" to yes. |
| | 319 | |
| | 320 | - More detailed IKEv2 EAP payload information in debug output |
| | 321 | |
| | 322 | - IKEv2 EAP-SIM and EAP-AKA share joint libsimaka library |
| | 323 | |
| | 324 | - Added required userland changes for proper SHA256 and SHA384/512 in ESP that |
| | 325 | will be introduced with Linux 2.6.33. The "sha256"/"sha2_256" keyword now |
| | 326 | configures the kernel with 128 bit truncation, not the non-standard 96 |
| | 327 | bit truncation used by previous releases. To use the old 96 bit truncation |
| | 328 | scheme, the new "sha256_96" proposal keyword has been introduced. |
| | 329 | |
| | 330 | - Fixed IPComp in tunnel mode, stripping out the duplicated outer header. This |
| | 331 | change makes IPcomp tunnel mode connections incompatible with previous |
| | 332 | releases; disable compression on such tunnels. |
| | 333 | |
| | 334 | - Fixed BEET mode connections on recent kernels by installing SAs with |
| | 335 | appropriate traffic selectors, based on a patch by Michael Rossberg. |
| | 336 | |
| | 337 | - Using extensions (such as BEET mode) and crypto algorithms (such as twofish, |
| | 338 | serpent, sha256_96) allocated in the private use space now require that we |
| | 339 | know its meaning, i.e. we are talking to strongSwan. Use the new |
| | 340 | "charon.send_vendor_id" option in strongswan.conf to let the remote peer know |
| | 341 | this is the case. |
| | 342 | |
| | 343 | - Experimental support for draft-eronen-ipsec-ikev2-eap-auth, where the |
| | 344 | responder omits public key authentication in favor of a mutual authentication |
| | 345 | method. To enable EAP-only authentication, set rightauth=eap on the responder |
| | 346 | to rely only on the MSK constructed AUTH payload. This not-yet standardized |
| | 347 | extension requires the strongSwan vendor ID introduced above. |
| | 348 | |
| | 349 | - The IKEv1 daemon ignores the Juniper SRX notification type 40001, thus |
| | 350 | allowing interoperability. |
| | 351 | |
| | 352 | |
| | 353 | strongswan-4.3.5 |
| | 354 | ---------------- |
| | 355 | |
| | 356 | - The IKEv1 pluto daemon can now use SQL-based address pools to deal out |
| | 357 | virtual IP addresses as a Mode Config server. The pool capability has been |
| | 358 | migrated from charon's sql plugin to a new attr-sql plugin which is loaded |
| | 359 | by libstrongswan and which can be used by both daemons either with a SQLite |
| | 360 | or MySQL database and the corresponding plugin. |
| | 361 | |
| | 362 | - Plugin names have been streamlined: EAP plugins now have a dash after eap |
| | 363 | (e.g. eap-sim), as it is used with the --enable-eap-sim ./configure option. |
| | 364 | Plugin configuration sections in strongswan.conf now use the same name as the |
| | 365 | plugin itself (i.e. with a dash). Make sure to update "load" directives and |
| | 366 | the affected plugin sections in existing strongswan.conf files. |
| | 367 | |
| | 368 | - The private/public key parsing and encoding has been split up into |
| | 369 | separate pkcs1, pgp, pem and dnskey plugins. The public key implementation |
| | 370 | plugins gmp, gcrypt and openssl can all make use of them. |
| | 371 | |
| | 372 | - The EAP-AKA plugin can use different backends for USIM/quintuplet |
| | 373 | calculations, very similar to the EAP-SIM plugin. The existing 3GPP2 software |
| | 374 | implementation has been migrated to a separate plugin. |
| | 375 | |
| | 376 | - The IKEv2 daemon charon gained basic PGP support. It can use locally installed |
| | 377 | peer certificates and can issue signatures based on RSA private keys. |
| | 378 | |
| | 379 | - The new 'ipsec pki' tool provides a set of commands to maintain a public |
| | 380 | key infrastructure. It currently supports operations to create RSA and ECDSA |
| | 381 | private/public keys, calculate fingerprints and issue or verify certificates. |
| | 382 | |
| | 383 | - Charon uses a monotonic time source for statistics and job queueing, behaving |
| | 384 | correctly if the system time changes (e.g. when using NTP). |
| | 385 | |
| | 386 | - In addition to time based rekeying, charon supports IPsec SA lifetimes based |
| | 387 | on processed volume or number of packets. They new ipsec.conf paramaters |
| | 388 | 'lifetime' (an alias to 'keylife'), 'lifebytes' and 'lifepackets' handle |
| | 389 | SA timeouts, while the parameters 'margintime' (an alias to rekeymargin), |
| | 390 | 'marginbytes' and 'marginpackets' trigger the rekeying before a SA expires. |
| | 391 | The existing parameter 'rekeyfuzz' affects all margins. |
| | 392 | |
| | 393 | - If no CA/Gateway certificate is specified in the NetworkManager plugin, |
| | 394 | charon uses a set of trusted root certificates preinstalled by distributions. |
| | 395 | The directory containing CA certificates can be specified using the |
| | 396 | --with-nm-ca-dir=path configure option. |
| | 397 | |
| | 398 | - Fixed the encoding of the Email relative distinguished name in left|rightid |
| | 399 | statements. |
| | 400 | |
| | 401 | - Fixed the broken parsing of PKCS#7 wrapped certificates by the pluto daemon. |
| | 402 | |
| | 403 | - Fixed smartcard-based authentication in the pluto daemon which was broken by |
| | 404 | the ECDSA support introduced with the 4.3.2 release. |
| | 405 | |
| | 406 | - A patch contributed by Heiko Hund fixes mixed IPv6 in IPv4 and vice versa |
| | 407 | tunnels established with the IKEv1 pluto daemon. |
| | 408 | |
| | 409 | - The pluto daemon now uses the libstrongswan x509 plugin for certificates and |
| | 410 | CRls and the struct id type was replaced by identification_t used by charon |
| | 411 | and the libstrongswan library. |
| | 412 | |
| | 413 | |
| | 414 | strongswan-4.3.4 |
| | 415 | ---------------- |
| | 416 | |
| | 417 | - IKEv2 charon daemon ported to FreeBSD and Mac OS X. Installation details can |
| | 418 | be found on wiki.strongswan.org. |
| | 419 | |
| | 420 | - ipsec statusall shows the number of bytes transmitted and received over |
| | 421 | ESP connections configured by the IKEv2 charon daemon. |
| | 422 | |
| | 423 | - The IKEv2 charon daemon supports include files in ipsec.secrets. |
| | 424 | |
| | 425 | |
| | 426 | strongswan-4.3.3 |
| | 427 | ---------------- |
| | 428 | |
| | 429 | - The configuration option --enable-integrity-test plus the strongswan.conf |
| | 430 | option libstrongswan.integrity_test = yes activate integrity tests |
| | 431 | of the IKE daemons charon and pluto, libstrongswan and all loaded |
| | 432 | plugins. Thus dynamic library misconfigurations and non-malicious file |
| | 433 | manipulations can be reliably detected. |
| | 434 | |
| | 435 | - The new default setting libstrongswan.ecp_x_coordinate_only=yes allows |
| | 436 | IKEv1 interoperability with MS Windows using the ECP DH groups 19 and 20. |
| | 437 | |
| | 438 | - The IKEv1 pluto daemon now supports the AES-CCM and AES-GCM ESP |
| | 439 | authenticated encryption algorithms. |
| | 440 | |
| | 441 | - The IKEv1 pluto daemon now supports V4 OpenPGP keys. |
| | 442 | |
| | 443 | - The RDN parser vulnerability discovered by Orange Labs research team |
| | 444 | was not completely fixed in version 4.3.2. Some more modifications |
| | 445 | had to be applied to the asn1_length() function to make it robust. |
| | 446 | |
| | 447 | |
| | 448 | strongswan-4.3.2 |
| | 449 | ---------------- |
| | 450 | |
| | 451 | - The new gcrypt plugin provides symmetric cipher, hasher, RNG, Diffie-Hellman |
| | 452 | and RSA crypto primitives using the LGPL licensed GNU gcrypt library. |
| | 453 | |
| | 454 | - libstrongswan features an integrated crypto selftest framework for registered |
| | 455 | algorithms. The test-vector plugin provides a first set of test vectors and |
| | 456 | allows pluto and charon to rely on tested crypto algorithms. |
| | 457 | |
| | 458 | - pluto can now use all libstrongswan plugins with the exception of x509 and xcbc. |
| | 459 | Thanks to the openssl plugin, the ECP Diffie-Hellman groups 19, 20, 21, 25, and |
| | 460 | 26 as well as ECDSA-256, ECDSA-384, and ECDSA-521 authentication can be used |
| | 461 | with IKEv1. |
| | 462 | |
| | 463 | - Applying their fuzzing tool, the Orange Labs vulnerability research team found |
| | 464 | another two DoS vulnerabilities, one in the rather old ASN.1 parser of Relative |
| | 465 | Distinguished Names (RDNs) and a second one in the conversion of ASN.1 UTCTIME |
| | 466 | and GENERALIZEDTIME strings to a time_t value. |
| | 467 | |
| | 468 | |
| | 469 | strongswan-4.3.1 |
| | 470 | ---------------- |
| | 471 | |
| | 472 | - The nm plugin now passes DNS/NBNS server information to NetworkManager, |
| | 473 | allowing a gateway administrator to set DNS/NBNS configuration on clients |
| | 474 | dynamically. |
| | 475 | |
| | 476 | - The nm plugin also accepts CA certificates for gateway authentication. If |
| | 477 | a CA certificate is configured, strongSwan uses the entered gateway address |
| | 478 | as its idenitity, requiring the gateways certificate to contain the same as |
| | 479 | subjectAltName. This allows a gateway administrator to deploy the same |
| | 480 | certificates to Windows 7 and NetworkManager clients. |
| | 481 | |
| | 482 | - The command ipsec purgeike deletes IKEv2 SAs that don't have a CHILD SA. |
| | 483 | The command ipsec down <conn>{n} deletes CHILD SA instance n of connection |
| | 484 | <conn> whereas ipsec down <conn>{*} deletes all CHILD SA instances. |
| | 485 | The command ipsec down <conn>[n] deletes IKE SA instance n of connection |
| | 486 | <conn> plus dependent CHILD SAs whereas ipsec down <conn>[*] deletes all |
| | 487 | IKE SA instances of connection <conn>. |
| | 488 | |
| | 489 | - Fixed a regression introduced in 4.3.0 where EAP authentication calculated |
| | 490 | the AUTH payload incorrectly. Further, the EAP-MSCHAPv2 MSK key derivation |
| | 491 | has been updated to be compatible with the Windows 7 Release Candidate. |
| | 492 | |
| | 493 | - Refactored installation of triggering policies. Routed policies are handled |
| | 494 | outside of IKE_SAs to keep them installed in any case. A tunnel gets |
| | 495 | established only once, even if initiation is delayed due network outages. |
| | 496 | |
| | 497 | - Improved the handling of multiple acquire signals triggered by the kernel. |
| | 498 | |
| | 499 | - Fixed two DoS vulnerabilities in the charon daemon that were discovered by |
| | 500 | fuzzing techniques: 1) Sending a malformed IKE_SA_INIT request leaved an |
| | 501 | incomplete state which caused a null pointer dereference if a subsequent |
| | 502 | CREATE_CHILD_SA request was sent. 2) Sending an IKE_AUTH request with either |
| | 503 | a missing TSi or TSr payload caused a null pointer derefence because the |
| | 504 | checks for TSi and TSr were interchanged. The IKEv2 fuzzer used was |
| | 505 | developped by the Orange Labs vulnerability research team. The tool was |
| | 506 | initially written by Gabriel Campana and is now maintained by Laurent Butti. |
| | 507 | |
| | 508 | - Added support for AES counter mode in ESP in IKEv2 using the proposal |
| | 509 | keywords aes128ctr, aes192ctr and aes256ctr. |
| | 510 | |
| | 511 | - Further progress in refactoring pluto: Use of the curl and ldap plugins |
| | 512 | for fetching crls and OCSP. Use of the random plugin to get keying material |
| | 513 | from /dev/random or /dev/urandom. Use of the openssl plugin as an alternative |
| | 514 | to the aes, des, sha1, sha2, and md5 plugins. The blowfish, twofish, and |
| | 515 | serpent encryption plugins are now optional and are not enabled by default. |
| | 516 | |
| | 517 | |
| | 518 | strongswan-4.3.0 |
| | 519 | ---------------- |
| | 520 | |
| | 521 | - Support for the IKEv2 Multiple Authentication Exchanges extension (RFC4739). |
| | 522 | Initiators and responders can use several authentication rounds (e.g. RSA |
| | 523 | followed by EAP) to authenticate. The new ipsec.conf leftauth/rightauth and |
| | 524 | leftauth2/rightauth2 parameters define own authentication rounds or setup |
| | 525 | constraints for the remote peer. See the ipsec.conf man page for more detials. |
| | 526 | |
| | 527 | - If glibc printf hooks (register_printf_function) are not available, |
| | 528 | strongSwan can use the vstr string library to run on non-glibc systems. |
| | 529 | |
| | 530 | - The IKEv2 charon daemon can now configure the ESP CAMELLIA-CBC cipher |
| | 531 | (esp=camellia128|192|256). |
| | 532 | |
| | 533 | - Refactored the pluto and scepclient code to use basic functions (memory |
| | 534 | allocation, leak detective, chunk handling, printf_hooks, strongswan.conf |
| | 535 | attributes, ASN.1 parser, etc.) from the libstrongswan library. |
| | 536 | |
| | 537 | - Up to two DNS and WINS servers to be sent via IKEv1 ModeConfig can be |
| | 538 | configured in the pluto section of strongswan.conf. |
| | 539 | |
| | 540 | |
| | 541 | strongswan-4.2.14 |
| | 542 | ----------------- |
| | 543 | |
| | 544 | - The new server-side EAP RADIUS plugin (--enable-eap-radius) |
| | 545 | relays EAP messages to and from a RADIUS server. Succesfully |
| | 546 | tested with with a freeradius server using EAP-MD5 and EAP-SIM. |
| | 547 | |
| | 548 | - A vulnerability in the Dead Peer Detection (RFC 3706) code was found by |
| | 549 | Gerd v. Egidy <gerd.von.egidy@intra2net.com> of Intra2net AG affecting |
| | 550 | all Openswan and strongSwan releases. A malicious (or expired ISAKMP) |
| | 551 | R_U_THERE or R_U_THERE_ACK Dead Peer Detection packet can cause the |
| | 552 | pluto IKE daemon to crash and restart. No authentication or encryption |
| | 553 | is required to trigger this bug. One spoofed UDP packet can cause the |
| | 554 | pluto IKE daemon to restart and be unresponsive for a few seconds while |
| | 555 | restarting. This DPD null state vulnerability has been officially |
| | 556 | registered as CVE-2009-0790 and is fixed by this release. |
| | 557 | |
| | 558 | - ASN.1 to time_t conversion caused a time wrap-around for |
| | 559 | dates after Jan 18 03:14:07 UTC 2038 on 32-bit platforms. |
| | 560 | As a workaround such dates are set to the maximum representable |
| | 561 | time, i.e. Jan 19 03:14:07 UTC 2038. |
| | 562 | |
| | 563 | - Distinguished Names containing wildcards (*) are not sent in the |
| | 564 | IDr payload anymore. |
| | 565 | |
| | 566 | |
| | 567 | strongswan-4.2.13 |
| | 568 | ----------------- |
| | 569 | |
| | 570 | - Fixed a use-after-free bug in the DPD timeout section of the |
| | 571 | IKEv1 pluto daemon which sporadically caused a segfault. |
| | 572 | |
| | 573 | - Fixed a crash in the IKEv2 charon daemon occuring with |
| | 574 | mixed RAM-based and SQL-based virtual IP address pools. |
| | 575 | |
| | 576 | - Fixed ASN.1 parsing of algorithmIdentifier objects where the |
| | 577 | parameters field is optional. |
| | 578 | |
| | 579 | - Ported nm plugin to NetworkManager 7.1. |
| | 580 | |
| | 581 | |
| | 582 | strongswan-4.2.12 |
| | 583 | ----------------- |
| | 584 | |
| | 585 | - Support of the EAP-MSCHAPv2 protocol enabled by the option |
| | 586 | --enable-eap-mschapv2. Requires the MD4 hash algorithm enabled |
| | 587 | either by --enable-md4 or --enable-openssl. |
| | 588 | |
| | 589 | - Assignment of up to two DNS and up to two WINS servers to peers via |
| | 590 | the IKEv2 Configuration Payload (CP). The IPv4 or IPv6 nameserver |
| | 591 | addresses are defined in strongswan.conf. |
| | 592 | |
| | 593 | - The strongSwan applet for the Gnome NetworkManager is now built and |
| | 594 | distributed as a separate tarball under the name NetworkManager-strongswan. |
| | 595 | |
| | 596 | |
| | 597 | strongswan-4.2.11 |
| | 598 | ----------------- |
| | 599 | |
| | 600 | - Fixed ESP NULL encryption broken by the refactoring of keymat.c. |
| | 601 | Also introduced proper initialization and disposal of keying material. |
| | 602 | |
| | 603 | - Fixed the missing listing of connection definitions in ipsec statusall |
| | 604 | broken by an unfortunate local variable overload. |
| | 605 | |
| | 606 | |
| | 607 | strongswan-4.2.10 |
| | 608 | ----------------- |
| | 609 | |
| | 610 | - Several performance improvements to handle thousands of tunnels with almost |
| | 611 | linear upscaling. All relevant data structures have been replaced by faster |
| | 612 | counterparts with better lookup times. |
| | 613 | |
| | 614 | - Better parallelization to run charon on multiple cores. Due to improved |
| | 615 | ressource locking and other optimizations the daemon can take full |
| | 616 | advantage of 16 or even more cores. |
| | 617 | |
| | 618 | - The load-tester plugin can use a NULL Diffie-Hellman group and simulate |
| | 619 | unique identities and certificates by signing peer certificates using a CA |
| | 620 | on the fly. |
| | 621 | |
| | 622 | - The redesigned stroke in-memory IP pool handles leases. The "ipsec leases" |
| | 623 | command queries assigned leases. |
| | 624 | |
| | 625 | - Added support for smartcards in charon by using the ENGINE API provided by |
| | 626 | OpenSSL, based on patches by Michael Roßberg. |
| | 627 | |
| | 628 | - The Padlock plugin supports the hardware RNG found on VIA CPUs to provide a |
| | 629 | reliable source of randomness. |
| | 630 | |
| | 631 | strongswan-4.2.9 |
| | 632 | ---------------- |
| | 633 | |
| | 634 | - Flexible configuration of logging subsystem allowing to log to multiple |
| | 635 | syslog facilities or to files using fine-grained log levels for each target. |
| | 636 | |
| | 637 | - Load testing plugin to do stress testing of the IKEv2 daemon against self |
| | 638 | or another host. Found and fixed issues during tests in the multi-threaded |
| | 639 | use of the OpenSSL plugin. |
| | 640 | |
| | 641 | - Added profiling code to synchronization primitives to find bottlenecks if |
| | 642 | running on multiple cores. Found and fixed an issue where parts of the |
| | 643 | Diffie-Hellman calculation acquired an exclusive lock. This greatly improves |
| | 644 | parallelization to multiple cores. |
| | 645 | |
| | 646 | - updown script invocation has been separated into a plugin of its own to |
| | 647 | further slim down the daemon core. |
| | 648 | |
| | 649 | - Separated IKE_SA/CHILD_SA key derivation process into a closed system, |
| | 650 | allowing future implementations to use a secured environment in e.g. kernel |
| | 651 | memory or hardware. |
| | 652 | |
| | 653 | - The kernel interface of charon has been modularized. XFRM NETLINK (default) |
| | 654 | and PFKEY (--enable-kernel-pfkey) interface plugins for the native IPsec |
| | 655 | stack of the Linux 2.6 kernel as well as a PFKEY interface for the KLIPS |
| | 656 | IPsec stack (--enable-kernel-klips) are provided. |
| | 657 | |
| | 658 | - Basic Mobile IPv6 support has been introduced, securing Binding Update |
| | 659 | messages as well as tunneled traffic between Mobile Node and Home Agent. |
| | 660 | The installpolicy=no option allows peaceful cooperation with a dominant |
| | 661 | mip6d daemon and the new type=transport_proxy implements the special MIPv6 |
| | 662 | IPsec transport proxy mode where the IKEv2 daemon uses the Care-of-Address |
| | 663 | but the IPsec SA is set up for the Home Adress. |
| | 664 | |
| | 665 | - Implemented migration of Mobile IPv6 connections using the KMADDRESS |
| | 666 | field contained in XFRM_MSG_MIGRATE messages sent by the mip6d daemon |
| | 667 | via the Linux 2.6.28 (or appropriately patched) kernel. |
| | 668 | |
| | 669 | |
| | 670 | strongswan-4.2.8 |
| | 671 | ---------------- |
| | 672 | |
| | 673 | - IKEv2 charon daemon supports authentication based on raw public keys |
| | 674 | stored in the SQL database backend. The ipsec listpubkeys command |
| | 675 | lists the available raw public keys via the stroke interface. |
| | 676 | |
| | 677 | - Several MOBIKE improvements: Detect changes in NAT mappings in DPD exchanges, |
| | 678 | handle events if kernel detects NAT mapping changes in UDP-encapsulated |
| | 679 | ESP packets (requires kernel patch), reuse old addesses in MOBIKE updates as |
| | 680 | long as possible and other fixes. |
| | 681 | |
| | 682 | - Fixed a bug in addr_in_subnet() which caused insertion of wrong source |
| | 683 | routes for destination subnets having netwmasks not being a multiple of 8 bits. |
| | 684 | Thanks go to Wolfgang Steudel, TU Ilmenau for reporting this bug. |
| | 685 | |
| | 686 | |
| | 687 | strongswan-4.2.7 |
| | 688 | ---------------- |
| | 689 | |
| | 690 | - Fixed a Denial-of-Service vulnerability where an IKE_SA_INIT message with |
| | 691 | a KE payload containing zeroes only can cause a crash of the IKEv2 charon |
| | 692 | daemon due to a NULL pointer returned by the mpz_export() function of the |
| | 693 | GNU Multiprecision Library (GMP). Thanks go to Mu Dynamics Research Labs |
| | 694 | for making us aware of this problem. |
| | 695 | |
| | 696 | - The new agent plugin provides a private key implementation on top of an |
| | 697 | ssh-agent. |
| | 698 | |
| | 699 | - The NetworkManager plugin has been extended to support certificate client |
| | 700 | authentication using RSA keys loaded from a file or using ssh-agent. |
| | 701 | |
| | 702 | - Daemon capability dropping has been ported to libcap and must be enabled |
| | 703 | explicitly --with-capabilities=libcap. Future version will support the |
| | 704 | newer libcap2 library. |
| | 705 | |
| | 706 | - ipsec listalgs lists the IKEv2 cryptografic algorithms registered with the |
| | 707 | charon keying daemon. |
| | 708 | |
| | 709 | |
| | 710 | strongswan-4.2.6 |
| | 711 | ---------------- |
| | 712 | |
| | 713 | - A NetworkManager plugin allows GUI-based configuration of road-warrior |
| | 714 | clients in a simple way. It features X509 based gateway authentication |
| | 715 | and EAP client authentication, tunnel setup/teardown and storing passwords |
| | 716 | in the Gnome Keyring. |
| | 717 | |
| | 718 | - A new EAP-GTC plugin implements draft-sheffer-ikev2-gtc-00.txt and allows |
| | 719 | username/password authentication against any PAM service on the gateway. |
| | 720 | The new EAP method interacts nicely with the NetworkManager plugin and allows |
| | 721 | client authentication against e.g. LDAP. |
| | 722 | |
| | 723 | - Improved support for the EAP-Identity method. The new ipsec.conf eap_identity |
| | 724 | parameter defines an additional identity to pass to the server in EAP |
| | 725 | authentication. |
| | 726 | |
| | 727 | - The "ipsec statusall" command now lists CA restrictions, EAP |
| | 728 | authentication types and EAP identities. |
| | 729 | |
| | 730 | - Fixed two multithreading deadlocks occurring when starting up |
| | 731 | several hundred tunnels concurrently. |
| | 732 | |
| | 733 | - Fixed the --enable-integrity-test configure option which |
| | 734 | computes a SHA-1 checksum over the libstrongswan library. |
| | 735 | |
| | 736 | |
| | 737 | strongswan-4.2.5 |
| | 738 | ---------------- |
| | 739 | |
| | 740 | - Consistent logging of IKE and CHILD SAs at the audit (AUD) level. |
| | 741 | |
| | 742 | - Improved the performance of the SQL-based virtual IP address pool |
| | 743 | by introducing an additional addresses table. The leases table |
| | 744 | storing only history information has become optional and can be |
| | 745 | disabled by setting charon.plugins.sql.lease_history = no in |
| | 746 | strongswan.conf. |
| | 747 | |
| | 748 | - The XFRM_STATE_AF_UNSPEC flag added to xfrm.h allows IPv4-over-IPv6 |
| | 749 | and IPv6-over-IPv4 tunnels with the 2.6.26 and later Linux kernels. |
| | 750 | |
| | 751 | - management of different virtual IP pools for different |
| | 752 | network interfaces have become possible. |
| | 753 | |
| | 754 | - fixed a bug which prevented the assignment of more than 256 |
| | 755 | virtual IP addresses from a pool managed by an sql database. |
| | 756 | |
| | 757 | - fixed a bug which did not delete own IPCOMP SAs in the kernel. |
| | 758 | |
| | 759 | |
| | 760 | strongswan-4.2.4 |
| | 761 | ---------------- |
| | 762 | |
| | 763 | - Added statistics functions to ipsec pool --status and ipsec pool --leases |
| | 764 | and input validation checks to various ipsec pool commands. |
| | 765 | |
| | 766 | - ipsec statusall now lists all loaded charon plugins and displays |
| | 767 | the negotiated IKEv2 cipher suite proposals. |
| | 768 | |
| | 769 | - The openssl plugin supports the elliptic curve Diffie-Hellman groups |
| | 770 | 19, 20, 21, 25, and 26. |
| | 771 | |
| | 772 | - The openssl plugin supports ECDSA authentication using elliptic curve |
| | 773 | X.509 certificates. |
| | 774 | |
| | 775 | - Fixed a bug in stroke which caused multiple charon threads to close |
| | 776 | the file descriptors during packet transfers over the stroke socket. |
| | 777 | |
| | 778 | - ESP sequence numbers are now migrated in IPsec SA updates handled by |
| | 779 | MOBIKE. Works only with Linux kernels >= 2.6.17. |
| | 780 | |
| | 781 | |
| | 782 | strongswan-4.2.3 |
| | 783 | ---------------- |
| | 784 | |
| | 785 | - Fixed the strongswan.conf path configuration problem that occurred when |
| | 786 | --sysconfig was not set explicitly in ./configure. |
| | 787 | |
| | 788 | - Fixed a number of minor bugs that where discovered during the 4th |
| | 789 | IKEv2 interoperability workshop in San Antonio, TX. |
| | 790 | |
| | 791 | |
| | 792 | strongswan-4.2.2 |
| | 793 | ---------------- |
| | 794 | |
| | 795 | - Plugins for libstrongswan and charon can optionally be loaded according |
| | 796 | to a configuration in strongswan.conf. Most components provide a |
| | 797 | "load = " option followed by a space separated list of plugins to load. |
| | 798 | This allows e.g. the fallback from a hardware crypto accelerator to |
| | 799 | to software-based crypto plugins. |
| | 800 | |
| | 801 | - Charons SQL plugin has been extended by a virtual IP address pool. |
| | 802 | Configurations with a rightsourceip=%poolname setting query a SQLite or |
| | 803 | MySQL database for leases. The "ipsec pool" command helps in administrating |
| | 804 | the pool database. See ipsec pool --help for the available options |
| | 805 | |
| | 806 | - The Authenticated Encryption Algorithms AES-CCM-8/12/16 and AES-GCM-8/12/16 |
| | 807 | for ESP are now supported starting with the Linux 2.6.25 kernel. The |
| | 808 | syntax is e.g. esp=aes128ccm12 or esp=aes256gcm16. |
| | 809 | |
| | 810 | |
| | 811 | strongswan-4.2.1 |
| | 812 | ---------------- |
| | 813 | |
| | 814 | - Support for "Hash and URL" encoded certificate payloads has been implemented |
| | 815 | in the IKEv2 daemon charon. Using the "certuribase" option of a CA section |
| | 816 | allows to assign a base URL to all certificates issued by the specified CA. |
| | 817 | The final URL is then built by concatenating that base and the hex encoded |
| | 818 | SHA1 hash of the DER encoded certificate. Note that this feature is disabled |
| | 819 | by default and must be enabled using the option "charon.hash_and_url". |
| | 820 | |
| | 821 | - The IKEv2 daemon charon now supports the "uniqueids" option to close multiple |
| | 822 | IKE_SAs with the same peer. The option value "keep" prefers existing |
| | 823 | connection setups over new ones, where the value "replace" replaces existing |
| | 824 | connections. |
| | 825 | |
| | 826 | - The crypto factory in libstrongswan additionaly supports random number |
| | 827 | generators, plugins may provide other sources of randomness. The default |
| | 828 | plugin reads raw random data from /dev/(u)random. |
| | 829 | |
| | 830 | - Extended the credential framework by a caching option to allow plugins |
| | 831 | persistent caching of fetched credentials. The "cachecrl" option has been |
| | 832 | re-implemented. |
| | 833 | |
| | 834 | - The new trustchain verification introduced in 4.2.0 has been parallelized. |
| | 835 | Threads fetching CRL or OCSP information no longer block other threads. |
| | 836 | |
| | 837 | - A new IKEv2 configuration attribute framework has been introduced allowing |
| | 838 | plugins to provide virtual IP addresses, and in the future, other |
| | 839 | configuration attribute services (e.g. DNS/WINS servers). |
| | 840 | |
| | 841 | - The stroke plugin has been extended to provide virtual IP addresses from |
| | 842 | a pool defined in ipsec.conf. The "rightsourceip" parameter now accepts |
| | 843 | address pools in CIDR notation (e.g. 10.1.1.0/24). The parameter also accepts |
| | 844 | the value "%poolname", where "poolname" identifies a pool provided by a |
| | 845 | separate plugin. |
| | 846 | |
| | 847 | - Fixed compilation on uClibc and a couple of other minor bugs. |
| | 848 | |
| | 849 | - Set DPD defaults in ipsec starter to dpd_delay=30s and dpd_timeout=150s. |
| | 850 | |
| | 851 | - The IKEv1 pluto daemon now supports the ESP encryption algorithm CAMELLIA |
| | 852 | with key lengths of 128, 192, and 256 bits, as well as the authentication |
| | 853 | algorithm AES_XCBC_MAC. Configuration example: esp=camellia192-aesxcbc. |
| | 854 | |
| | 855 | |
| | 856 | strongswan-4.2.0 |
| | 857 | ---------------- |
| | 858 | |
| | 859 | - libstrongswan has been modularized to attach crypto algorithms, |
| | 860 | credential implementations (keys, certificates) and fetchers dynamically |
| | 861 | through plugins. Existing code has been ported to plugins: |
| | 862 | - RSA/Diffie-Hellman implementation using the GNU Multi Precision library |
| | 863 | - X509 certificate system supporting CRLs, OCSP and attribute certificates |
| | 864 | - Multiple plugins providing crypto algorithms in software |
| | 865 | - CURL and OpenLDAP fetcher |
| | 866 | |
| | 867 | - libstrongswan gained a relational database API which uses pluggable database |
| | 868 | providers. Plugins for MySQL and SQLite are available. |
| | 869 | |
| | 870 | - The IKEv2 keying daemon charon is more extensible. Generic plugins may provide |
| | 871 | connection configuration, credentials and EAP methods or control the daemon. |
| | 872 | Existing code has been ported to plugins: |
| | 873 | - EAP-AKA, EAP-SIM, EAP-MD5 and EAP-Identity |
| | 874 | - stroke configuration, credential and control (compatible to pluto) |
| | 875 | - XML bases management protocol to control and query the daemon |
| | 876 | The following new plugins are available: |
| | 877 | - An experimental SQL configuration, credential and logging plugin on |
| | 878 | top of either MySQL or SQLite |
| | 879 | - A unit testing plugin to run tests at daemon startup |
| | 880 | |
| | 881 | - The authentication and credential framework in charon has been heavily |
| | 882 | refactored to support modular credential providers, proper |
| | 883 | CERTREQ/CERT payload exchanges and extensible authorization rules. |
| | 884 | |
| | 885 | - The framework of strongSwan Manager has envolved to the web application |
| | 886 | framework libfast (FastCGI Application Server w/ Templates) and is usable |
| | 887 | by other applications. |
| | 888 | |
| | 889 | |
| | 890 | strongswan-4.1.11 |
| | 891 | ----------------- |
| | 892 | |
| | 893 | - IKE rekeying in NAT situations did not inherit the NAT conditions |
| | 894 | to the rekeyed IKE_SA so that the UDP encapsulation was lost with |
| | 895 | the next CHILD_SA rekeying. |
| | 896 | |
| | 897 | - Wrong type definition of the next_payload variable in id_payload.c |
| | 898 | caused an INVALID_SYNTAX error on PowerPC platforms. |
| | 899 | |
| | 900 | - Implemented IKEv2 EAP-SIM server and client test modules that use |
| | 901 | triplets stored in a file. For details on the configuration see |
| | 902 | the scenario 'ikev2/rw-eap-sim-rsa'. |
| | 903 | |
| | 904 | |
| | 905 | strongswan-4.1.10 |
| | 906 | ----------------- |
| | 907 | |
| | 908 | - Fixed error in the ordering of the certinfo_t records in the ocsp cache that |
| | 909 | caused multiple entries of the same serial number to be created. |
| | 910 | |
| | 911 | - Implementation of a simple EAP-MD5 module which provides CHAP |
| | 912 | authentication. This may be interesting in conjunction with certificate |
| | 913 | based server authentication, as weak passwords can't be brute forced |
| | 914 | (in contradiction to traditional IKEv2 PSK). |
| | 915 | |
| | 916 | - A complete software based implementation of EAP-AKA, using algorithms |
| | 917 | specified in 3GPP2 (S.S0055). This implementation does not use an USIM, |
| | 918 | but reads the secrets from ipsec.secrets. Make sure to read eap_aka.h |
| | 919 | before using it. |
| | 920 | |
| | 921 | - Support for vendor specific EAP methods using Expanded EAP types. The |
| | 922 | interface to EAP modules has been slightly changed, so make sure to |
| | 923 | check the changes if you're already rolling your own modules. |
| | 924 | |
| | 925 | |
| | 926 | strongswan-4.1.9 |
| | 927 | ---------------- |
| | 928 | |
| | 929 | - The default _updown script now dynamically inserts and removes ip6tables |
| | 930 | firewall rules if leftfirewall=yes is set in IPv6 connections. New IPv6 |
| | 931 | net-net and roadwarrior (PSK/RSA) scenarios for both IKEv1 and IKEV2 were |
| | 932 | added. |
| | 933 | |
| | 934 | - Implemented RFC4478 repeated authentication to force EAP/Virtual-IP clients |
| | 935 | to reestablish an IKE_SA within a given timeframe. |
| | 936 | |
| | 937 | - strongSwan Manager supports configuration listing, initiation and termination |
| | 938 | of IKE and CHILD_SAs. |
| | 939 | |
| | 940 | - Fixes and improvements to multithreading code. |
| | 941 | |
| | 942 | - IKEv2 plugins have been renamed to libcharon-* to avoid naming conflicts. |
| | 943 | Make sure to remove the old plugins in $libexecdir/ipsec, otherwise they get |
| | 944 | loaded twice. |
| | 945 | |
| | 946 | |
| | 947 | strongswan-4.1.8 |
| | 948 | ---------------- |
| | 949 | |
| | 950 | - Removed recursive pthread mutexes since uClibc doesn't support them. |
| | 951 | |
| | 952 | |
| | 953 | strongswan-4.1.7 |
| | 954 | ---------------- |
| | 955 | |
| | 956 | - In NAT traversal situations and multiple queued Quick Modes, |
| | 957 | those pending connections inserted by auto=start after the |
| | 958 | port floating from 500 to 4500 were erronously deleted. |
| | 959 | |
| | 960 | - Added a "forceencaps" connection parameter to enforce UDP encapsulation |
| | 961 | to surmount restrictive firewalls. NAT detection payloads are faked to |
| | 962 | simulate a NAT situation and trick the other peer into NAT mode (IKEv2 only). |
| | 963 | |
| | 964 | - Preview of strongSwan Manager, a web based configuration and monitoring |
| | 965 | application. It uses a new XML control interface to query the IKEv2 daemon |
| | 966 | (see http://wiki.strongswan.org/wiki/Manager). |
| | 967 | |
| | 968 | - Experimental SQLite configuration backend which will provide the configuration |
| | 969 | interface for strongSwan Manager in future releases. |
| | 970 | |
| | 971 | - Further improvements to MOBIKE support. |
| | 972 | |
| | 973 | |
| | 974 | strongswan-4.1.6 |
| | 975 | ---------------- |
| | 976 | |
| | 977 | - Since some third party IKEv2 implementations run into |
| | 978 | problems with strongSwan announcing MOBIKE capability per |
| | 979 | default, MOBIKE can be disabled on a per-connection-basis |
| | 980 | using the mobike=no option. Whereas mobike=no disables the |
| | 981 | sending of the MOBIKE_SUPPORTED notification and the floating |
| | 982 | to UDP port 4500 with the IKE_AUTH request even if no NAT |
| | 983 | situation has been detected, strongSwan will still support |
| | 984 | MOBIKE acting as a responder. |
| | 985 | |
| | 986 | - the default ipsec routing table plus its corresponding priority |
| | 987 | used for inserting source routes has been changed from 100 to 220. |
| | 988 | It can be configured using the --with-ipsec-routing-table and |
| | 989 | --with-ipsec-routing-table-prio options. |
| | 990 | |
| | 991 | - the --enable-integrity-test configure option tests the |
| | 992 | integrity of the libstrongswan crypto code during the charon |
| | 993 | startup. |
| | 994 | |
| | 995 | - the --disable-xauth-vid configure option disables the sending |
| | 996 | of the XAUTH vendor ID. This can be used as a workaround when |
| | 997 | interoperating with some Windows VPN clients that get into |
| | 998 | trouble upon reception of an XAUTH VID without eXtended |
| | 999 | AUTHentication having been configured. |
| | 1000 | |
| | 1001 | - ipsec stroke now supports the rereadsecrets, rereadaacerts, |
| | 1002 | rereadacerts, and listacerts options. |
| | 1003 | |
| | 1004 | |
| | 1005 | strongswan-4.1.5 |
| | 1006 | ---------------- |
| | 1007 | |
| | 1008 | - If a DNS lookup failure occurs when resolving right=%<FQDN> |
| | 1009 | or right=<FQDN> combined with rightallowany=yes then the |
| | 1010 | connection is not updated by ipsec starter thus preventing |
| | 1011 | the disruption of an active IPsec connection. Only if the DNS |
| | 1012 | lookup successfully returns with a changed IP address the |
| | 1013 | corresponding connection definition is updated. |
| | 1014 | |
| | 1015 | - Routes installed by the keying daemons are now in a separate |
| | 1016 | routing table with the ID 100 to avoid conflicts with the main |
| | 1017 | table. Route lookup for IKEv2 traffic is done in userspace to ignore |
| | 1018 | routes installed for IPsec, as IKE traffic shouldn't get encapsulated. |
| | 1019 | |
| | 1020 | |
| | 1021 | strongswan-4.1.4 |
| | 1022 | ---------------- |
| | 1023 | |
| | 1024 | - The pluto IKEv1 daemon now exhibits the same behaviour as its |
| | 1025 | IKEv2 companion charon by inserting an explicit route via the |
| | 1026 | _updown script only if a sourceip exists. This is admissible |
| | 1027 | since routing through the IPsec tunnel is handled automatically |
| | 1028 | by NETKEY's IPsec policies. As a consequence the left|rightnexthop |
| | 1029 | parameter is not required any more. |
| | 1030 | |
| | 1031 | - The new IKEv1 parameter right|leftallowany parameters helps to handle |
| | 1032 | the case where both peers possess dynamic IP addresses that are |
| | 1033 | usually resolved using DynDNS or a similar service. The configuration |
| | 1034 | |
| | 1035 | right=peer.foo.bar |
| | 1036 | rightallowany=yes |
| | 1037 | |
| | 1038 | can be used by the initiator to start up a connection to a peer |
| | 1039 | by resolving peer.foo.bar into the currently allocated IP address. |
| | 1040 | Thanks to the rightallowany flag the connection behaves later on |
| | 1041 | as |
| | 1042 | |
| | 1043 | right=%any |
| | 1044 | |
| | 1045 | so that the peer can rekey the connection as an initiator when his |
| | 1046 | IP address changes. An alternative notation is |
| | 1047 | |
| | 1048 | right=%peer.foo.bar |
| | 1049 | |
| | 1050 | which will implicitly set rightallowany=yes. |
| | 1051 | |
| | 1052 | - ipsec starter now fails more gracefully in the presence of parsing |
| | 1053 | errors. Flawed ca and conn section are discarded and pluto is started |
| | 1054 | if non-fatal errors only were encountered. If right=%peer.foo.bar |
| | 1055 | cannot be resolved by DNS then right=%any will be used so that passive |
| | 1056 | connections as a responder are still possible. |
| | 1057 | |
| | 1058 | - The new pkcs11initargs parameter that can be placed in the |
| | 1059 | setup config section of /etc/ipsec.conf allows the definition |
| | 1060 | of an argument string that is used with the PKCS#11 C_Initialize() |
| | 1061 | function. This non-standard feature is required by the NSS softoken |
| | 1062 | library. This patch was contributed by Robert Varga. |
| | 1063 | |
| | 1064 | - Fixed a bug in ipsec starter introduced by strongswan-2.8.5 |
| | 1065 | which caused a segmentation fault in the presence of unknown |
| | 1066 | or misspelt keywords in ipsec.conf. This bug fix was contributed |
| | 1067 | by Robert Varga. |
| | 1068 | |
| | 1069 | - Partial support for MOBIKE in IKEv2. The initiator acts on interface/ |
| | 1070 | address configuration changes and updates IKE and IPsec SAs dynamically. |
| | 1071 | |
| | 1072 | |
| | 1073 | strongswan-4.1.3 |
| | 1074 | ---------------- |
| | 1075 | |
| | 1076 | - IKEv2 peer configuration selection now can be based on a given |
| | 1077 | certification authority using the rightca= statement. |
| | 1078 | |
| | 1079 | - IKEv2 authentication based on RSA signatures now can handle multiple |
| | 1080 | certificates issued for a given peer ID. This allows a smooth transition |
| | 1081 | in the case of a peer certificate renewal. |
| | 1082 | |
| | 1083 | - IKEv2: Support for requesting a specific virtual IP using leftsourceip on the |
| | 1084 | client and returning requested virtual IPs using rightsourceip=%config |
| | 1085 | on the server. If the server does not support configuration payloads, the |
| | 1086 | client enforces its leftsourceip parameter. |
| | 1087 | |
| | 1088 | - The ./configure options --with-uid/--with-gid allow pluto and charon |
| | 1089 | to drop their privileges to a minimum and change to an other UID/GID. This |
| | 1090 | improves the systems security, as a possible intruder may only get the |
| | 1091 | CAP_NET_ADMIN capability. |
| | 1092 | |
| | 1093 | - Further modularization of charon: Pluggable control interface and |
| | 1094 | configuration backend modules provide extensibility. The control interface |
| | 1095 | for stroke is included, and further interfaces using DBUS (NetworkManager) |
| | 1096 | or XML are on the way. A backend for storing configurations in the daemon |
| | 1097 | is provided and more advanced backends (using e.g. a database) are trivial |
| | 1098 | to implement. |
| | 1099 | |
| | 1100 | - Fixed a compilation failure in libfreeswan occuring with Linux kernel |
| | 1101 | headers > 2.6.17. |
| | 1102 | |
| | 1103 | |
| | 1104 | strongswan-4.1.2 |
| | 1105 | ---------------- |
| | 1106 | |
| | 1107 | - Support for an additional Diffie-Hellman exchange when creating/rekeying |
| | 1108 | a CHILD_SA in IKEv2 (PFS). PFS is enabled when the proposal contains a |
| | 1109 | DH group (e.g. "esp=aes128-sha1-modp1536"). Further, DH group negotiation |
| | 1110 | is implemented properly for rekeying. |
| | 1111 | |
| | 1112 | - Support for the AES-XCBC-96 MAC algorithm for IPsec SAs when using IKEv2 |
| | 1113 | (requires linux >= 2.6.20). It is enabled using e.g. "esp=aes256-aesxcbc". |
| | 1114 | |
| | 1115 | - Working IPv4-in-IPv6 and IPv6-in-IPv4 tunnels for linux >= 2.6.21. |
| | 1116 | |
| | 1117 | - Added support for EAP modules which do not establish an MSK. |
| | 1118 | |
| | 1119 | - Removed the dependencies from the /usr/include/linux/ headers by |
| | 1120 | including xfrm.h, ipsec.h, and pfkeyv2.h in the distribution. |
| | 1121 | |
| | 1122 | - crlNumber is now listed by ipsec listcrls |
| | 1123 | |
| | 1124 | - The xauth_modules.verify_secret() function now passes the |
| | 1125 | connection name. |
| | 1126 | |
| | 1127 | |
| | 1128 | strongswan-4.1.1 |
| | 1129 | ---------------- |
| | 1130 | |
| | 1131 | - Server side cookie support. If to may IKE_SAs are in CONNECTING state, |
| | 1132 | cookies are enabled and protect against DoS attacks with faked source |
| | 1133 | addresses. Number of IKE_SAs in CONNECTING state is also limited per |
| | 1134 | peer address to avoid resource exhaustion. IKE_SA_INIT messages are |
| | 1135 | compared to properly detect retransmissions and incoming retransmits are |
| | 1136 | detected even if the IKE_SA is blocked (e.g. doing OCSP fetches). |
| | 1137 | |
| | 1138 | - The IKEv2 daemon charon now supports dynamic http- and ldap-based CRL |
| | 1139 | fetching enabled by crlcheckinterval > 0 and caching fetched CRLs |
| | 1140 | enabled by cachecrls=yes. |
| | 1141 | |
| | 1142 | - Added the configuration options --enable-nat-transport which enables |
| | 1143 | the potentially insecure NAT traversal for IPsec transport mode and |
| | 1144 | --disable-vendor-id which disables the sending of the strongSwan |
| | 1145 | vendor ID. |
| | 1146 | |
| | 1147 | - Fixed a long-standing bug in the pluto IKEv1 daemon which caused |
| | 1148 | a segmentation fault if a malformed payload was detected in the |
| | 1149 | IKE MR2 message and pluto tried to send an encrypted notification |
| | 1150 | message. |
| | 1151 | |
| | 1152 | - Added the NATT_IETF_02_N Vendor ID in order to support IKEv1 connections |
| | 1153 | with Windows 2003 Server which uses a wrong VID hash. |
| | 1154 | |
| | 1155 | |
| | 1156 | strongswan-4.1.0 |
| | 1157 | ---------------- |
| | 1158 | |
| | 1159 | - Support of SHA2_384 hash function for protecting IKEv1 |
| | 1160 | negotiations and support of SHA2 signatures in X.509 certificates. |
| | 1161 | |
| | 1162 | - Fixed a serious bug in the computation of the SHA2-512 HMAC |
| | 1163 | function. Introduced automatic self-test of all IKEv1 hash |
| | 1164 | and hmac functions during pluto startup. Failure of a self-test |
| | 1165 | currently issues a warning only but does not exit pluto [yet]. |
| | 1166 | |
| | 1167 | - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2. |
| | 1168 | |
| | 1169 | - Full support of CA information sections. ipsec listcainfos |
| | 1170 | now shows all collected crlDistributionPoints and OCSP |
| | 1171 | accessLocations. |
| | 1172 | |
| | 1173 | - Support of the Online Certificate Status Protocol (OCSP) for IKEv2. |
| | 1174 | This feature requires the HTTP fetching capabilities of the libcurl |
| | 1175 | library which must be enabled by setting the --enable-http configure |
| | 1176 | option. |
| | 1177 | |
| | 1178 | - Refactored core of the IKEv2 message processing code, allowing better |
| | 1179 | code reuse and separation. |
| | 1180 | |
| | 1181 | - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration |
| | 1182 | payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted |
| | 1183 | by the requestor and installed in a resolv.conf file. |
| | 1184 | |
| | 1185 | - The IKEv2 daemon charon installs a route for each IPsec policy to use |
| | 1186 | the correct source address even if an application does not explicitly |
| | 1187 | specify it. |
| | 1188 | |
| | 1189 | - Integrated the EAP framework into charon which loads pluggable EAP library |
| | 1190 | modules. The ipsec.conf parameter authby=eap initiates EAP authentication |
| | 1191 | on the client side, while the "eap" parameter on the server side defines |
| | 1192 | the EAP method to use for client authentication. |
| | 1193 | A generic client side EAP-Identity module and an EAP-SIM authentication |
| | 1194 | module using a third party card reader implementation are included. |
| | 1195 | |
| | 1196 | - Added client side support for cookies. |
| | 1197 | |
| | 1198 | - Integrated the fixes done at the IKEv2 interoperability bakeoff, including |
| | 1199 | strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor |
| | 1200 | fixes to enhance interoperability with other implementations. |
| | 1201 | |
| | 1202 | |
| | 1203 | strongswan-4.0.7 |
| | 1204 | ---------------- |
| | 1205 | |
| | 1206 | - strongSwan now interoperates with the NCP Secure Entry Client, |
| | 1207 | the Shrew Soft VPN Client, and the Cisco VPN client, doing both |
| | 1208 | XAUTH and Mode Config. |
| | 1209 | |
| | 1210 | - UNITY attributes are now recognized and UNITY_BANNER is set |
| | 1211 | to a default string. |
| | 1212 | |
| | 1213 | |
| | 1214 | strongswan-4.0.6 |
| | 1215 | ---------------- |
| | 1216 | |
| | 1217 | - IKEv1: Support for extended authentication (XAUTH) in combination |
| | 1218 | with ISAKMP Main Mode RSA or PSK authentication. Both client and |
| | 1219 | server side were implemented. Handling of user credentials can |
| | 1220 | be done by a run-time loadable XAUTH module. By default user |
| | 1221 | credentials are stored in ipsec.secrets. |
| | 1222 | |
| | 1223 | - IKEv2: Support for reauthentication when rekeying |
| | 1224 | |
| | 1225 | - IKEv2: Support for transport mode |
| | 1226 | |
| | 1227 | - fixed a lot of bugs related to byte order |
| | 1228 | |
| | 1229 | - various other bugfixes |
| | 1230 | |
| | 1231 | |
| | 1232 | strongswan-4.0.5 |
| | 1233 | ---------------- |
| | 1234 | |
| | 1235 | - IKEv1: Implementation of ModeConfig push mode via the new connection |
| | 1236 | keyword modeconfig=push allows interoperability with Cisco VPN gateways. |
| | 1237 | |
| | 1238 | - IKEv1: The command ipsec statusall now shows "DPD active" for all |
| | 1239 | ISAKMP SAs that are under active Dead Peer Detection control. |
| | 1240 | |
| | 1241 | - IKEv2: Charon's logging and debugging framework has been completely rewritten. |
| | 1242 | Instead of logger, special printf() functions are used to directly |
| | 1243 | print objects like hosts (%H) identifications (%D), certificates (%Q), |
| | 1244 | etc. The number of debugging levels have been reduced to: |
| | 1245 | |
| | 1246 | 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private) |
| | 1247 | |
| | 1248 | The debugging levels can either be specified statically in ipsec.conf as |
| | 1249 | |
| | 1250 | config setup |
| | 1251 | charondebug="lib 1, cfg 3, net 2" |
| | 1252 | |
| | 1253 | or changed at runtime via stroke as |
| | 1254 | |
| | 1255 | ipsec stroke loglevel cfg 2 |
| | 1256 | |
| | 1257 | |
| | 1258 | strongswan-4.0.4 |
| | 1259 | ---------------- |
| | 1260 | |
| | 1261 | - Implemented full support for IPv6-in-IPv6 tunnels. |
| | 1262 | |
| | 1263 | - Added configuration options for dead peer detection in IKEv2. dpd_action |
| | 1264 | types "clear", "hold" and "restart" are supported. The dpd_timeout |
| | 1265 | value is not used, as the normal retransmission policy applies to |
| | 1266 | detect dead peers. The dpd_delay parameter enables sending of empty |
| | 1267 | informational message to detect dead peers in case of inactivity. |
| | 1268 | |
| | 1269 | - Added support for preshared keys in IKEv2. PSK keys configured in |
| | 1270 | ipsec.secrets are loaded. The authby parameter specifies the authentication |
| | 1271 | method to authentificate ourself, the other peer may use PSK or RSA. |
| | 1272 | |
| | 1273 | - Changed retransmission policy to respect the keyingtries parameter. |
| | 1274 | |
| | 1275 | - Added private key decryption. PEM keys encrypted with AES-128/192/256 |
| | 1276 | or 3DES are supported. |
| | 1277 | |
| | 1278 | - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to |
| | 1279 | encrypt IKE traffic. |
| | 1280 | |
| | 1281 | - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates |
| | 1282 | signed with such a hash algorithm. |
| | 1283 | |
| | 1284 | - Added initial support for updown scripts. The actions up-host/client and |
| | 1285 | down-host/client are executed. The leftfirewall=yes parameter |
| | 1286 | uses the default updown script to insert dynamic firewall rules, a custom |
| | 1287 | updown script may be specified with the leftupdown parameter. |
| | 1288 | |
| | 1289 | |
| | 1290 | strongswan-4.0.3 |
| | 1291 | ---------------- |
| | 1292 | |
| | 1293 | - Added support for the auto=route ipsec.conf parameter and the |
| | 1294 | ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and |
| | 1295 | CHILD_SAs dynamically on demand when traffic is detected by the |
| | 1296 | kernel. |
| | 1297 | |
| | 1298 | - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter. |
| | 1299 | As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only |
| | 1300 | new keys are generated using perfect forward secrecy. An optional flag |
| | 1301 | which enforces reauthentication will be implemented later. |
| | 1302 | |
| | 1303 | - "sha" and "sha1" are now treated as synonyms in the ike= and esp= |
| | 1304 | algorithm configuration statements. |
| | 1305 | |
| | 1306 | |
| | 1307 | strongswan-4.0.2 |
| | 1308 | ---------------- |
| | 1309 | |
| | 1310 | - Full X.509 certificate trust chain verification has been implemented. |
| | 1311 | End entity certificates can be exchanged via CERT payloads. The current |
| | 1312 | default is leftsendcert=always, since CERTREQ payloads are not supported |
| | 1313 | yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls. |
| | 1314 | |
| | 1315 | - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2 |
| | 1316 | would offer more possibilities for traffic selection, but the Linux kernel |
| | 1317 | currently does not support it. That's why we stick with these simple |
| | 1318 | ipsec.conf rules for now. |
| | 1319 | |
| | 1320 | - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no |
| | 1321 | IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear, |
| | 1322 | dpddelay=60s). |
| | 1323 | |
| | 1324 | - Initial NAT traversal support in IKEv2. Charon includes NAT detection |
| | 1325 | notify payloads to detect NAT routers between the peers. It switches |
| | 1326 | to port 4500, uses UDP encapsulated ESP packets, handles peer address |
| | 1327 | changes gracefully and sends keep alive message periodically. |
| | 1328 | |
| | 1329 | - Reimplemented IKE_SA state machine for charon, which allows simultaneous |
| | 1330 | rekeying, more shared code, cleaner design, proper retransmission |
| | 1331 | and a more extensible code base. |
| | 1332 | |
| | 1333 | - The mixed PSK/RSA roadwarrior detection capability introduced by the |
| | 1334 | strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal |
| | 1335 | payloads by the responder right before any defined IKE Main Mode state had |
| | 1336 | been established. Although any form of bad proposal syntax was being correctly |
| | 1337 | detected by the payload parser, the subsequent error handler didn't check |
| | 1338 | the state pointer before logging current state information, causing an |
| | 1339 | immediate crash of the pluto keying daemon due to a NULL pointer. |
| | 1340 | |
| | 1341 | |
| | 1342 | strongswan-4.0.1 |
| | 1343 | ---------------- |
| | 1344 | |
| | 1345 | - Added algorithm selection to charon: New default algorithms for |
| | 1346 | ike=aes128-sha-modp2048, as both daemons support it. The default |
| | 1347 | for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles |
| | 1348 | the ike/esp parameter the same way as pluto. As this syntax does |
| | 1349 | not allow specification of a pseudo random function, the same |
| | 1350 | algorithm as for integrity is used (currently sha/md5). Supported |
| | 1351 | algorithms for IKE: |
| | 1352 | Encryption: aes128, aes192, aes256 |
| | 1353 | Integrity/PRF: md5, sha (using hmac) |
| | 1354 | DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192 |
| | 1355 | and for ESP: |
| | 1356 | Encryption: aes128, aes192, aes256, 3des, blowfish128, |
| | 1357 | blowfish192, blowfish256 |
| | 1358 | Integrity: md5, sha1 |
| | 1359 | More IKE encryption algorithms will come after porting libcrypto into |
| | 1360 | libstrongswan. |
| | 1361 | |
| | 1362 | - initial support for rekeying CHILD_SAs using IKEv2. Currently no |
| | 1363 | perfect forward secrecy is used. The rekeying parameters rekey, |
| | 1364 | rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported |
| | 1365 | when using IKEv2. WARNING: charon currently is unable to handle |
| | 1366 | simultaneous rekeying. To avoid such a situation, use a large |
| | 1367 | rekeyfuzz, or even better, set rekey=no on one peer. |
| | 1368 | |
| | 1369 | - support for host2host, net2net, host2net (roadwarrior) tunnels |
| | 1370 | using predefined RSA certificates (see uml scenarios for |
| | 1371 | configuration examples). |
| | 1372 | |
| | 1373 | - new build environment featuring autotools. Features such |
| | 1374 | as HTTP, LDAP and smartcard support may be enabled using |
| | 1375 | the ./configure script. Changing install directories |
| | 1376 | is possible, too. See ./configure --help for more details. |
| | 1377 | |
| | 1378 | - better integration of charon with ipsec starter, which allows |
| | 1379 | (almost) transparent operation with both daemons. charon |
| | 1380 | handles ipsec commands up, down, status, statusall, listall, |
| | 1381 | listcerts and allows proper load, reload and delete of connections |
| | 1382 | via ipsec starter. |
| | 1383 | |
| | 1384 | |
| | 1385 | strongswan-4.0.0 |
| | 1386 | ---------------- |
| | 1387 | |
| | 1388 | - initial support of the IKEv2 protocol. Connections in |
| | 1389 | ipsec.conf designated by keyexchange=ikev2 are negotiated |
| | 1390 | by the new IKEv2 charon keying daemon whereas those marked |
| | 1391 | by keyexchange=ikev1 or the default keyexchange=ike are |
| | 1392 | handled thy the IKEv1 pluto keying daemon. Currently only |
| | 1393 | a limited subset of functions are available with IKEv2 |
| | 1394 | (Default AES encryption, authentication based on locally |
| | 1395 | imported X.509 certificates, unencrypted private RSA keys |
| | 1396 | in PKCS#1 file format, limited functionality of the ipsec |
| | 1397 | status command). |
| | 1398 | |
| | 1399 | |
| | 1400 | strongswan-2.7.0 |
| | 1401 | ---------------- |
| | 1402 | |
| | 1403 | - the dynamic iptables rules from the _updown_x509 template |
| | 1404 | for KLIPS and the _updown_policy template for NETKEY have |
| | 1405 | been merged into the default _updown script. The existing |
| | 1406 | left|rightfirewall keyword causes the automatic insertion |
| | 1407 | and deletion of ACCEPT rules for tunneled traffic upon |
| | 1408 | the successful setup and teardown of an IPsec SA, respectively. |
| | 1409 | left|rightfirwall can be used with KLIPS under any Linux 2.4 |
| | 1410 | kernel or with NETKEY under a Linux kernel version >= 2.6.16 |
| | 1411 | in conjuction with iptables >= 1.3.5. For NETKEY under a Linux |
| | 1412 | kernel version < 2.6.16 which does not support IPsec policy |
| | 1413 | matching yet, please continue to use a copy of the _updown_espmark |
| | 1414 | template loaded via the left|rightupdown keyword. |
| | 1415 | |
| | 1416 | - a new left|righthostaccess keyword has been introduced which |
| | 1417 | can be used in conjunction with left|rightfirewall and the |
| | 1418 | default _updown script. By default leftfirewall=yes inserts |
| | 1419 | a bi-directional iptables FORWARD rule for a local client network |
| | 1420 | with a netmask different from 255.255.255.255 (single host). |
| | 1421 | This does not allow to access the VPN gateway host via its |
| | 1422 | internal network interface which is part of the client subnet |
| | 1423 | because an iptables INPUT and OUTPUT rule would be required. |
| | 1424 | lefthostaccess=yes will cause this additional ACCEPT rules to |
| | 1425 | be inserted. |
| | 1426 | |
| | 1427 | - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal |
| | 1428 | payload is preparsed in order to find out whether the roadwarrior |
| | 1429 | requests PSK or RSA so that a matching connection candidate can |
| | 1430 | be found. |
| | 1431 | |
| | 1432 | |
| | 1433 | strongswan-2.6.4 |
| | 1434 | ---------------- |
| | 1435 | |
| | 1436 | - the new _updown_policy template allows ipsec policy based |
| | 1437 | iptables firewall rules. Required are iptables version |
| | 1438 | >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes |
| | 1439 | the _updown_espmark template, so that no INPUT mangle rules |
| | 1440 | are required any more. |
| | 1441 | |
| | 1442 | - added support of DPD restart mode |
| | 1443 | |
| | 1444 | - ipsec starter now allows the use of wildcards in include |
| | 1445 | statements as e.g. in "include /etc/my_ipsec/*.conf". |
| | 1446 | Patch courtesy of Matthias Haas. |
| | 1447 | |
| | 1448 | - the Netscape OID 'employeeNumber' is now recognized and can be |
| | 1449 | used as a Relative Distinguished Name in certificates. |
| | 1450 | |
| | 1451 | |
| | 1452 | strongswan-2.6.3 |
| | 1453 | ---------------- |
| | 1454 | |
| | 1455 | - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec |
| | 1456 | command and not of ipsec setup any more. |
| | 1457 | |
| | 1458 | - ipsec starter now supports AH authentication in conjunction with |
| | 1459 | ESP encryption. AH authentication is configured in ipsec.conf |
| | 1460 | via the auth=ah parameter. |
| | 1461 | |
| | 1462 | - The command ipsec scencrypt|scdecrypt <args> is now an alias for |
| | 1463 | ipsec whack --scencrypt|scdecrypt <args>. |
| | 1464 | |
| | 1465 | - get_sa_info() now determines for the native netkey IPsec stack |
| | 1466 | the exact time of the last use of an active eroute. This information |
| | 1467 | is used by the Dead Peer Detection algorithm and is also displayed by |
| | 1468 | the ipsec status command. |
| | 1469 | |
| | 1470 | |
| | 1471 | strongswan-2.6.2 |
| | 1472 | ---------------- |
| | 1473 | |
| | 1474 | - running under the native Linux 2.6 IPsec stack, the function |
| | 1475 | get_sa_info() is called by ipsec auto --status to display the current |
| | 1476 | number of transmitted bytes per IPsec SA. |
| | 1477 | |
| | 1478 | - get_sa_info() is also used by the Dead Peer Detection process to detect |
| | 1479 | recent ESP activity. If ESP traffic was received from the peer within |
| | 1480 | the last dpd_delay interval then no R_Y_THERE notification must be sent. |
| | 1481 | |
| | 1482 | - strongSwan now supports the Relative Distinguished Name "unstructuredName" |
| | 1483 | in ID_DER_ASN1_DN identities. The following notations are possible: |
| | 1484 | |
| | 1485 | rightid="unstructuredName=John Doe" |
| | 1486 | rightid="UN=John Doe" |
| | 1487 | |
| | 1488 | - fixed a long-standing bug which caused PSK-based roadwarrior connections |
| | 1489 | to segfault in the function id.c:same_id() called by keys.c:get_secret() |
| | 1490 | if an FQDN, USER_FQDN, or Key ID was defined, as in the following example. |
| | 1491 | |
| | 1492 | conn rw |
| | 1493 | right=%any |
| | 1494 | rightid=@foo.bar |
| | 1495 | authby=secret |
| | 1496 | |
| | 1497 | - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall). |
| | 1498 | |
| | 1499 | - ipsec starter didn't set host_addr and client.addr ports in whack msg. |
| | 1500 | |
| | 1501 | - in order to guarantee backwards-compatibility with the script-based |
| | 1502 | auto function (e.g. auto --replace), the ipsec starter scripts stores |
| | 1503 | the defaultroute information in the temporary file /var/run/ipsec.info. |
| | 1504 | |
| | 1505 | - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH |
| | 1506 | Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config |
| | 1507 | servers. |
| | 1508 | |
| | 1509 | - the ipsec starter now also recognizes the parameters authby=never and |
| | 1510 | type=passthrough|pass|drop|reject. |
| | 1511 | |
| | 1512 | |
| | 1513 | strongswan-2.6.1 |
| | 1514 | ---------------- |
| | 1515 | |
| | 1516 | - ipsec starter now supports the also parameter which allows |
| | 1517 | a modular structure of the connection definitions. Thus |
| | 1518 | "ipsec start" is now ready to replace "ipsec setup". |
| | 1519 | |
| | 1520 | |
| | 1521 | strongswan-2.6.0 |
| | 1522 | ---------------- |
| | 1523 | |
| | 1524 | - Mathieu Lafon's popular ipsec starter tool has been added to the |
| | 1525 | strongSwan distribution. Many thanks go to Stephan Scholz from astaro |
| | 1526 | for his integration work. ipsec starter is a C program which is going |
| | 1527 | to replace the various shell and awk starter scripts (setup, _plutoload, |
| | 1528 | _plutostart, _realsetup, _startklips, _confread, and auto). Since |
| | 1529 | ipsec.conf is now parsed only once, the starting of multiple tunnels is |
| | 1530 | accelerated tremedously. |
| | 1531 | |
| | 1532 | - Added support of %defaultroute to the ipsec starter. If the IP address |
| | 1533 | changes, a HUP signal to the ipsec starter will automatically |
| | 1534 | reload pluto's connections. |
| | 1535 | |
| | 1536 | - moved most compile time configurations from pluto/Makefile to |
| | 1537 | Makefile.inc by defining the options USE_LIBCURL, USE_LDAP, |
| | 1538 | USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE. |
| | 1539 | |
| | 1540 | - removed the ipsec verify and ipsec newhostkey commands |
| | 1541 | |
| | 1542 | - fixed some 64-bit issues in formatted print statements |
| | 1543 | |
| | 1544 | - The scepclient functionality implementing the Simple Certificate |
| | 1545 | Enrollment Protocol (SCEP) is nearly complete but hasn't been |
| | 1546 | documented yet. |
| | 1547 | |
| | 1548 | |
| | 1549 | strongswan-2.5.7 |
| | 1550 | ---------------- |
| | 1551 | |
| | 1552 | - CA certicates are now automatically loaded from a smartcard |
| | 1553 | or USB crypto token and appear in the ipsec auto --listcacerts |
| | 1554 | listing. |
| | 1555 | |
| | 1556 | |
| | 1557 | strongswan-2.5.6 |
| | 1558 | ---------------- |
| | 1559 | |
| | 1560 | - when using "ipsec whack --scencrypt <data>" with a PKCS#11 |
| | 1561 | library that does not support the C_Encrypt() Cryptoki |
| | 1562 | function (e.g. OpenSC), the RSA encryption is done in |
| | 1563 | software using the public key fetched from the smartcard. |
| | 1564 | |
| | 1565 | - The scepclient function now allows to define the |
| | 1566 | validity of a self-signed certificate using the --days, |
| | 1567 | --startdate, and --enddate options. The default validity |
| | 1568 | has been changed from one year to five years. |
| | 1569 | |
| | 1570 | |
| | 1571 | strongswan-2.5.5 |
| | 1572 | ---------------- |
| | 1573 | |
| | 1574 | - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11 |
| | 1575 | interface to other applications for RSA encryption and decryption |
| | 1576 | via the whack interface. Notation: |
| | 1577 | |
| | 1578 | ipsec whack --scencrypt <data> |
| | 1579 | [--inbase 16|hex|64|base64|256|text|ascii] |
| | 1580 | [--outbase 16|hex|64|base64|256|text|ascii] |
| | 1581 | [--keyid <keyid>] |
| | 1582 | |
| | 1583 | ipsec whack --scdecrypt <data> |
| | 1584 | [--inbase 16|hex|64|base64|256|text|ascii] |
| | 1585 | [--outbase 16|hex|64|base64|256|text|ascii] |
| | 1586 | [--keyid <keyid>] |
| | 1587 | |
| | 1588 | The default setting for inbase and outbase is hex. |
| | 1589 | |
| | 1590 | The new proxy interface can be used for securing symmetric |
| | 1591 | encryption keys required by the cryptoloop or dm-crypt |
| | 1592 | disk encryption schemes, especially in the case when |
| | 1593 | pkcs11keepstate=yes causes pluto to lock the pkcs11 slot |
| | 1594 | permanently. |
| | 1595 | |
| | 1596 | - if the file /etc/ipsec.secrets is lacking during the startup of |
| | 1597 | pluto then the root-readable file /etc/ipsec.d/private/myKey.der |
| | 1598 | containing a 2048 bit RSA private key and a matching self-signed |
| | 1599 | certificate stored in the file /etc/ipsec.d/certs/selfCert.der |
| | 1600 | is automatically generated by calling the function |
| | 1601 | |
| | 1602 | ipsec scepclient --out pkcs1 --out cert-self |
| | 1603 | |
| | 1604 | scepclient was written by Jan Hutter and Martin Willi, students |
| | 1605 | at the University of Applied Sciences in Rapperswil, Switzerland. |
| | 1606 | |
| | 1607 | |
| | 1608 | strongswan-2.5.4 |
| | 1609 | ---------------- |
| | 1610 | |
| | 1611 | - the current extension of the PKCS#7 framework introduced |
| | 1612 | a parsing error in PKCS#7 wrapped X.509 certificates that are |
| | 1613 | e.g. transmitted by Windows XP when multi-level CAs are used. |
| | 1614 | the parsing syntax has been fixed. |
| | 1615 | |
| | 1616 | - added a patch by Gerald Richter which tolerates multiple occurrences |
| | 1617 | of the ipsec0 interface when using KLIPS. |
| | 1618 | |
| | 1619 | |
| | 1620 | strongswan-2.5.3 |
| | 1621 | ---------------- |
| | 1622 | |
| | 1623 | - with gawk-3.1.4 the word "default2 has become a protected |
| | 1624 | keyword for use in switch statements and cannot be used any |
| | 1625 | more in the strongSwan scripts. This problem has been |
| | 1626 | solved by renaming "default" to "defaults" and "setdefault" |
| | 1627 | in the scripts _confread and auto, respectively. |
| | 1628 | |
| | 1629 | - introduced the parameter leftsendcert with the values |
| | 1630 | |
| | 1631 | always|yes (the default, always send a cert) |
| | 1632 | ifasked (send the cert only upon a cert request) |
| | 1633 | never|no (never send a cert, used for raw RSA keys and |
| | 1634 | self-signed certs) |
| | 1635 | |
| | 1636 | - fixed the initialization of the ESP key length to a default of |
| | 1637 | 128 bits in the case that the peer does not send a key length |
| | 1638 | attribute for AES encryption. |
| | 1639 | |
| | 1640 | - applied Herbert Xu's uniqueIDs patch |
| | 1641 | |
| | 1642 | - applied Herbert Xu's CLOEXEC patches |
| | 1643 | |
| | 1644 | |
| | 1645 | strongswan-2.5.2 |
| | 1646 | ---------------- |
| | 1647 | |
| | 1648 | - CRLs can now be cached also in the case when the issuer's |
| | 1649 | certificate does not contain a subjectKeyIdentifier field. |
| | 1650 | In that case the subjectKeyIdentifier is computed by pluto as the |
| | 1651 | 160 bit SHA-1 hash of the issuer's public key in compliance |
| | 1652 | with section 4.2.1.2 of RFC 3280. |
| | 1653 | |
| | 1654 | - Fixed a bug introduced by strongswan-2.5.1 which eliminated |
| | 1655 | not only multiple Quick Modes of a given connection but also |
| | 1656 | multiple connections between two security gateways. |
| | 1657 | |
| | 1658 | |
| | 1659 | strongswan-2.5.1 |
| | 1660 | ---------------- |
| | 1661 | |
| | 1662 | - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute |
| | 1663 | installed either by setting auto=route in ipsec.conf or by |
| | 1664 | a connection put into hold, generates an XFRM_AQUIRE event |
| | 1665 | for each packet that wants to use the not-yet exisiting |
| | 1666 | tunnel. Up to now each XFRM_AQUIRE event led to an entry in |
| | 1667 | the Quick Mode queue, causing multiple IPsec SA to be |
| | 1668 | established in rapid succession. Starting with strongswan-2.5.1 |
| | 1669 | only a single IPsec SA is established per host-pair connection. |
| | 1670 | |
| | 1671 | - Right after loading the PKCS#11 module, all smartcard slots are |
| | 1672 | searched for certificates. The result can be viewed using |
| | 1673 | the command |
| | 1674 | |
| | 1675 | ipsec auto --listcards |
| | 1676 | |
| | 1677 | The certificate objects found in the slots are numbered |
| | 1678 | starting with #1, #2, etc. This position number can be used to address |
| | 1679 | certificates (leftcert=%smartcard) and keys (: PIN %smartcard) |
| | 1680 | in ipsec.conf and ipsec.secrets, respectively: |
| | 1681 | |
| | 1682 | %smartcard (selects object #1) |
| | 1683 | %smartcard#1 (selects object #1) |
| | 1684 | %smartcard#3 (selects object #3) |
| | 1685 | |
| | 1686 | As an alternative the existing retrieval scheme can be used: |
| | 1687 | |
| | 1688 | %smartcard:45 (selects object with id=45) |
| | 1689 | %smartcard0 (selects first object in slot 0) |
| | 1690 | %smartcard4:45 (selects object in slot 4 with id=45) |
| | 1691 | |
| | 1692 | - Depending on the settings of CKA_SIGN and CKA_DECRYPT |
| | 1693 | private key flags either C_Sign() or C_Decrypt() is used |
| | 1694 | to generate a signature. |
| | 1695 | |
| | 1696 | - The output buffer length parameter siglen in C_Sign() |
| | 1697 | is now initialized to the actual size of the output |
| | 1698 | buffer prior to the function call. This fixes the |
| | 1699 | CKR_BUFFER_TOO_SMALL error that could occur when using |
| | 1700 | the OpenSC PKCS#11 module. |
| | 1701 | |
| | 1702 | - Changed the initialization of the PKCS#11 CK_MECHANISM in |
| | 1703 | C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }. |
| | 1704 | |
| | 1705 | - Refactored the RSA public/private key code and transferred it |
| | 1706 | from keys.c to the new pkcs1.c file as a preparatory step |
| | 1707 | towards the release of the SCEP client. |
| | 1708 | |
| | 1709 | |
| | 1710 | strongswan-2.5.0 |
| | 1711 | ---------------- |
| | 1712 | |
| | 1713 | - The loading of a PKCS#11 smartcard library module during |
| | 1714 | runtime does not require OpenSC library functions any more |
| | 1715 | because the corresponding code has been integrated into |
| | 1716 | smartcard.c. Also the RSAREF pkcs11 header files have been |
| | 1717 | included in a newly created pluto/rsaref directory so that |
| | 1718 | no external include path has to be defined any longer. |
| | 1719 | |
| | 1720 | - A long-awaited feature has been implemented at last: |
| | 1721 | The local caching of CRLs fetched via HTTP or LDAP, activated |
| | 1722 | by the parameter cachecrls=yes in the config setup section |
| | 1723 | of ipsec.conf. The dynamically fetched CRLs are stored under |
| | 1724 | a unique file name containing the issuer's subjectKeyID |
| | 1725 | in /etc/ipsec.d/crls. |
| | 1726 | |
| | 1727 | - Applied a one-line patch courtesy of Michael Richardson |
| | 1728 | from the Openswan project which fixes the kernel-oops |
| | 1729 | in KLIPS when an snmp daemon is running on the same box. |
| | 1730 | |
| | 1731 | |
| | 1732 | strongswan-2.4.4 |
| | 1733 | ---------------- |
| | 1734 | |
| | 1735 | - Eliminated null length CRL distribution point strings. |
| | 1736 | |
| | 1737 | - Fixed a trust path evaluation bug introduced with 2.4.3 |
| | 1738 | |
| | 1739 | |
| | 1740 | strongswan-2.4.3 |
| | 1741 | ---------------- |
| | 1742 | |
| | 1743 | - Improved the joint OCSP / CRL revocation policy. |
| | 1744 | OCSP responses have precedence over CRL entries. |
| | 1745 | |
| | 1746 | - Introduced support of CRLv2 reason codes. |
| | 1747 | |
| | 1748 | - Fixed a bug with key-pad equipped readers which caused |
| | 1749 | pluto to prompt for the pin via the console when the first |
| | 1750 | occasion to enter the pin via the key-pad was missed. |
| | 1751 | |
| | 1752 | - When pluto is built with LDAP_V3 enabled, the library |
| | 1753 | liblber required by newer versions of openldap is now |
| | 1754 | included. |
| | 1755 | |
| | 1756 | |
| | 1757 | strongswan-2.4.2 |
| | 1758 | ---------------- |
| | 1759 | |
| | 1760 | - Added the _updown_espmark template which requires all |
| | 1761 | incoming ESP traffic to be marked with a default mark |
| | 1762 | value of 50. |
| | 1763 | |
| | 1764 | - Introduced the pkcs11keepstate parameter in the config setup |
| | 1765 | section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11 |
| | 1766 | session and login states are kept as long as possible during |
| | 1767 | the lifetime of pluto. This means that a PIN entry via a key |
| | 1768 | pad has to be done only once. |
| | 1769 | |
| | 1770 | - Introduced the pkcs11module parameter in the config setup |
| | 1771 | section of ipsec.conf which specifies the PKCS#11 module |
| | 1772 | to be used with smart cards. Example: |
| | 1773 | |
| | 1774 | pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo |
| | 1775 | |
| | 1776 | - Added support of smartcard readers equipped with a PIN pad. |
| | 1777 | |
| | 1778 | - Added patch by Jay Pfeifer which detects when netkey |
| | 1779 | modules have been statically built into the Linux 2.6 kernel. |
| | 1780 | |
| | 1781 | - Added two patches by Herbert Xu. The first uses ip xfrm |
| | 1782 | instead of setkey to flush the IPsec policy database. The |
| | 1783 | second sets the optional flag in inbound IPComp SAs only. |
| | 1784 | |
| | 1785 | - Applied Ulrich Weber's patch which fixes an interoperability |
| | 1786 | problem between native IPsec and KLIPS systems caused by |
| | 1787 | setting the replay window to 32 instead of 0 for ipcomp. |
| | 1788 | |
| | 1789 | |
| | 1790 | strongswan-2.4.1 |
| | 1791 | ---------------- |
| | 1792 | |
| | 1793 | - Fixed a bug which caused an unwanted Mode Config request |
| | 1794 | to be initiated in the case where "right" was used to denote |
| | 1795 | the local side in ipsec.conf and "left" the remote side, |
| | 1796 | contrary to the recommendation that "right" be remote and |
| | 1797 | "left" be"local". |
| | 1798 | |
| | 1799 | |
| | 1800 | strongswan-2.4.0a |
| | 1801 | ----------------- |
| | 1802 | |
| | 1803 | - updated Vendor ID to strongSwan-2.4.0 |
| | 1804 | |
| | 1805 | - updated copyright statement to include David Buechi and |
| | 1806 | Michael Meier |
| | 1807 | |
| | 1808 | |
| | 1809 | strongswan-2.4.0 |
| | 1810 | ---------------- |
| | 1811 | |
| | 1812 | - strongSwan now communicates with attached smartcards and |
| | 1813 | USB crypto tokens via the standardized PKCS #11 interface. |
| | 1814 | By default the OpenSC library from www.opensc.org is used |
| | 1815 | but any other PKCS#11 library could be dynamically linked. |
| | 1816 | strongSwan's PKCS#11 API was implemented by David Buechi |
| | 1817 | and Michael Meier, both graduates of the Zurich University |
| | 1818 | of Applied Sciences in Winterthur, Switzerland. |
| | 1819 | |
| | 1820 | - When a %trap eroute is triggered by an outgoing IP packet |
| | 1821 | then the native IPsec stack of the Linux 2.6 kernel [often/ |
| | 1822 | always?] returns an XFRM_ACQUIRE message with an undefined |
| | 1823 | protocol family field and the connection setup fails. |
| | 1824 | As a workaround IPv4 (AF_INET) is now assumed. |
| | 1825 | |
| | 1826 | - the results of the UML test scenarios are now enhanced |
| | 1827 | with block diagrams of the virtual network topology used |
| | 1828 | in a particular test. |
| | 1829 | |
| | 1830 | |
| | 1831 | strongswan-2.3.2 |
| | 1832 | ---------------- |
| | 1833 | |
| | 1834 | - fixed IV used to decrypt informational messages. |
| | 1835 | This bug was introduced with Mode Config functionality. |
| | 1836 | |
| | 1837 | - fixed NCP Vendor ID. |
| | 1838 | |
| | 1839 | - undid one of Ulrich Weber's maximum udp size patches |
| | 1840 | because it caused a segmentation fault with NAT-ed |
| | 1841 | Delete SA messages. |
| | 1842 | |
| | 1843 | - added UML scenarios wildcards and attr-cert which |
| | 1844 | demonstrate the implementation of IPsec policies based |
| | 1845 | on wildcard parameters contained in Distinguished Names and |
| | 1846 | on X.509 attribute certificates, respectively. |
| | 1847 | |
| | 1848 | |
| | 1849 | strongswan-2.3.1 |
| | 1850 | ---------------- |
| | 1851 | |
| | 1852 | - Added basic Mode Config functionality |
| | 1853 | |
| | 1854 | - Added Mathieu Lafon's patch which upgrades the status of |
| | 1855 | the NAT-Traversal implementation to RFC 3947. |
| | 1856 | |
| | 1857 | - The _startklips script now also loads the xfrm4_tunnel |
| | 1858 | module. |
| | 1859 | |
| | 1860 | - Added Ulrich Weber's netlink replay window size and |
| | 1861 | maximum udp size patches. |
| | 1862 | |
| | 1863 | - UML testing now uses the Linux 2.6.10 UML kernel by default. |
| | 1864 | |
| | 1865 | |
| | 1866 | strongswan-2.3.0 |
| | 1867 | ---------------- |
| | 1868 | |
| | 1869 | - Eric Marchionni and Patrik Rayo, both recent graduates from |
| | 1870 | the Zuercher Hochschule Winterthur in Switzerland, created a |
| | 1871 | User-Mode-Linux test setup for strongSwan. For more details |
| | 1872 | please read the INSTALL and README documents in the testing |
| | 1873 | subdirectory. |
| | 1874 | |
| | 1875 | - Full support of group attributes based on X.509 attribute |
| | 1876 | certificates. Attribute certificates can be generated |
| | 1877 | using the openac facility. For more details see |
| | 1878 | |
| | 1879 | man ipsec_openac. |
| | 1880 | |
| | 1881 | The group attributes can be used in connection definitions |
| | 1882 | in order to give IPsec access to specific user groups. |
| | 1883 | This is done with the new parameter left|rightgroups as in |
| | 1884 | |
| | 1885 | rightgroups="Research, Sales" |
| | 1886 | |
| | 1887 | giving access to users possessing the group attributes |
| | 1888 | Research or Sales, only. |
| | 1889 | |
| | 1890 | - In Quick Mode clients with subnet mask /32 are now |
| | 1891 | coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should |
| | 1892 | fix rekeying problems with the SafeNet/SoftRemote and NCP |
| | 1893 | Secure Entry Clients. |
| | 1894 | |
| | 1895 | - Changed the defaults of the ikelifetime and keylife parameters |
| | 1896 | to 3h and 1h, respectively. The maximum allowable values are |
| | 1897 | now both set to 24 h. |
| | 1898 | |
| | 1899 | - Suppressed notification wars between two IPsec peers that |
| | 1900 | could e.g. be triggered by incorrect ISAKMP encryption. |
| | 1901 | |
| | 1902 | - Public RSA keys can now have identical IDs if either the |
| | 1903 | issuing CA or the serial number is different. The serial |
| | 1904 | number of a certificate is now shown by the command |
| | 1905 | |
| | 1906 | ipsec auto --listpubkeys |
| | 1907 | |
| | 1908 | |
| | 1909 | strongswan-2.2.2 |
| | 1910 | ---------------- |
| | 1911 | |
| | 1912 | - Added Tuomo Soini's sourceip feature which allows a strongSwan |
| | 1913 | roadwarrior to use a fixed Virtual IP (see README section 2.6) |
| | 1914 | and reduces the well-known four tunnel case on VPN gateways to |
| | 1915 | a single tunnel definition (see README section 2.4). |
| | 1916 | |
| | 1917 | - Fixed a bug occuring with NAT-Traversal enabled when the responder |
| | 1918 | suddenly turns initiator and the initiator cannot find a matching |
| | 1919 | connection because of the floated IKE port 4500. |
| | 1920 | |
| | 1921 | - Removed misleading ipsec verify command from barf. |
| | 1922 | |
| | 1923 | - Running under the native IP stack, ipsec --version now shows |
| | 1924 | the Linux kernel version (courtesy to the Openswan project). |
| | 1925 | |
| | 1926 | |
| | 1927 | strongswan-2.2.1 |
| | 1928 | ---------------- |
| | 1929 | |
| | 1930 | - Introduced the ipsec auto --listalgs monitoring command which lists |
| | 1931 | all currently registered IKE and ESP algorithms. |
| | 1932 | |
| | 1933 | - Fixed a bug in the ESP algorithm selection occuring when the strict flag |
| | 1934 | is set and the first proposed transform does not match. |
| | 1935 | |
| | 1936 | - Fixed another deadlock in the use of the lock_certs_and_keys() mutex, |
| | 1937 | occuring when a smartcard is present. |
| | 1938 | |
| | 1939 | - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event. |
| | 1940 | |
| | 1941 | - Fixed the printing of the notification names (null) |
| | 1942 | |
| | 1943 | - Applied another of Herbert Xu's Netlink patches. |
| | 1944 | |
| | 1945 | |
| | 1946 | strongswan-2.2.0 |
| | 1947 | ---------------- |
| | 1948 | |
| | 1949 | - Support of Dead Peer Detection. The connection parameter |
| | 1950 | |
| | 1951 | dpdaction=clear|hold |
| | 1952 | |
| | 1953 | activates DPD for the given connection. |
| | 1954 | |
| | 1955 | - The default Opportunistic Encryption (OE) policy groups are not |
| | 1956 | automatically included anymore. Those wishing to activate OE can include |
| | 1957 | the policy group with the following statement in ipsec.conf: |
| | 1958 | |
| | 1959 | include /etc/ipsec.d/examples/oe.conf |
| | 1960 | |
| | 1961 | The default for [right|left]rsasigkey is now set to %cert. |
| | 1962 | |
| | 1963 | - strongSwan now has a Vendor ID of its own which can be activated |
| | 1964 | using the compile option VENDORID |
| | 1965 | |
| | 1966 | - Applied Herbert Xu's patch which sets the compression algorithm correctly. |
| | 1967 | |
| | 1968 | - Applied Herbert Xu's patch fixing an ESPINUDP problem |
| | 1969 | |
| | 1970 | - Applied Herbert Xu's patch setting source/destination port numbers. |
| | 1971 | |
| | 1972 | - Reapplied one of Herbert Xu's NAT-Traversal patches which got |
| | 1973 | lost during the migration from SuperFreeS/WAN. |
| | 1974 | |
| | 1975 | - Fixed a deadlock in the use of the lock_certs_and_keys() mutex. |
| | 1976 | |
| | 1977 | - Fixed the unsharing of alg parameters when instantiating group |
| | 1978 | connection. |
| | 1979 | |
| | 1980 | |
| | 1981 | strongswan-2.1.5 |
| | 1982 | ---------------- |
| | 1983 | |
| | 1984 | - Thomas Walpuski made me aware of a potential DoS attack via |
| | 1985 | a PKCS#7-wrapped certificate bundle which could overwrite valid CA |
| | 1986 | certificates in Pluto's authority certificate store. This vulnerability |
| | 1987 | was fixed by establishing trust in CA candidate certificates up to a |
| | 1988 | trusted root CA prior to insertion into Pluto's chained list. |
| | 1989 | |
| | 1990 | - replaced the --assign option by the -v option in the auto awk script |
| | 1991 | in order to make it run with mawk under debian/woody. |
| | 1992 | |
| | 1993 | |
| | 1994 | strongswan-2.1.4 |
| | 1995 | ---------------- |
| | 1996 | |
| | 1997 | - Split of the status information between ipsec auto --status (concise) |
| | 1998 | and ipsec auto --statusall (verbose). Both commands can be used with |
| | 1999 | an optional connection selector: |
| | 2000 | |
| | 2001 | ipsec auto --status[all] <connection_name> |
| | 2002 | |
| | 2003 | - Added the description of X.509 related features to the ipsec_auto(8) |
| | 2004 | man page. |
| | 2005 | |
| | 2006 | - Hardened the ASN.1 parser in debug mode, especially the printing |
| | 2007 | of malformed distinguished names. |
| | 2008 | |
| | 2009 | - The size of an RSA public key received in a certificate is now restricted to |
| | 2010 | |
| | 2011 | 512 bits <= modulus length <= 8192 bits. |
| | 2012 | |
| | 2013 | - Fixed the debug mode enumeration. |
| | 2014 | |
| | 2015 | |
| | 2016 | strongswan-2.1.3 |
| | 2017 | ---------------- |
| | 2018 | |
| | 2019 | - Fixed another PKCS#7 vulnerability which could lead to an |
| | 2020 | endless loop while following the X.509 trust chain. |
| | 2021 | |
| | 2022 | |
| | 2023 | strongswan-2.1.2 |
| | 2024 | ---------------- |
| | 2025 | |
| | 2026 | - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski |
| | 2027 | that accepted end certificates having identical issuer and subject |
| | 2028 | distinguished names in a multi-tier X.509 trust chain. |
| | 2029 | |
| | 2030 | |
| | 2031 | strongswan-2.1.1 |
| | 2032 | ---------------- |
| | 2033 | |
| | 2034 | - Removed all remaining references to ipsec_netlink.h in KLIPS. |
| | 2035 | |
| | 2036 | |
| | 2037 | strongswan-2.1.0 |
| | 2038 | ---------------- |
| | 2039 | |
| | 2040 | - The new "ca" section allows to define the following parameters: |
| | 2041 | |
| | 2042 | ca kool |
| | 2043 | cacert=koolCA.pem # cacert of kool CA |
| | 2044 | ocspuri=http://ocsp.kool.net:8001 # ocsp server |
| | 2045 | ldapserver=ldap.kool.net # default ldap server |
| | 2046 | crluri=http://www.kool.net/kool.crl # crl distribution point |
| | 2047 | crluri2="ldap:///O=Kool, C= .." # crl distribution point #2 |
| | 2048 | auto=add # add, ignore |
| | 2049 | |
| | 2050 | The ca definitions can be monitored via the command |
| | 2051 | |
| | 2052 | ipsec auto --listcainfos |
| | 2053 | |
| | 2054 | - Fixed cosmetic corruption of /proc filesystem by integrating |
| | 2055 | D. Hugh Redelmeier's freeswan-2.06 kernel fixes. |
| | 2056 | |
| | 2057 | |
| | 2058 | strongswan-2.0.2 |
| | 2059 | ---------------- |
| | 2060 | |
| | 2061 | - Added support for the 818043 NAT-Traversal update of Microsoft's |
| | 2062 | Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode. |
| | 2063 | |
| | 2064 | - A symbolic link to libcrypto is now added in the kernel sources |
| | 2065 | during kernel compilation |
| | 2066 | |
| | 2067 | - Fixed a couple of 64 bit issues (mostly casts to int). |
| | 2068 | Thanks to Ken Bantoft who checked my sources on a 64 bit platform. |
| | 2069 | |
| | 2070 | - Replaced s[n]printf() statements in the kernel by ipsec_snprintf(). |
| | 2071 | Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro |
| | 2072 | of the FreeS/WAN team who solved this problem with the 2.4.25 kernel. |
| | 2073 | |
| | 2074 | |
| | 2075 | strongswan-2.0.1 |
| | 2076 | ---------------- |
| | 2077 | |
| | 2078 | - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName |
| | 2079 | certificate extension which contains no generalName item) can cause |
