| strongswan-5.3.2 | |
| ---------------- | |
| - Fixed a vulnerability that allowed rogue servers with a valid certificate | |
| accepted by the client to trick it into disclosing its username and even | |
| password (if the client accepts EAP-GTC). This was caused because constraints | |
| against the responder's authentication were enforced too late. | |
| This vulnerability has been registered as CVE-2015-4171. | |
| strongswan-5.3.1 | |
| ---------------- | |
| - Fixed a denial-of-service and potential remote code execution vulnerability | |
| triggered by IKEv1/IKEv2 messages that contain payloads for the respective | |
| other IKE version. Such payload are treated specially since 5.2.2 but because | |
| they were still identified by their original payload type they were used as | |
| such in some places causing invalid function pointer dereferences. | |
| The vulnerability has been registered as CVE-2015-3991. | |
| - The new aesni plugin provides CBC, CTR, XCBC, CMAC, CCM and GCM crypto | |
| primitives for AES-128/192/256. The plugin requires AES-NI and PCLMULQDQ | |
| instructions and works on both x86 and x64 architectures. It provides | |
| superior crypto performance in userland without any external libraries. | |
| strongswan-5.3.0 | |
| ---------------- | |
| - Added support for IKEv2 make-before-break reauthentication. By using a global | |
| CHILD_SA reqid allocation mechanism, charon supports overlapping CHILD_SAs. | |
| This allows the use of make-before-break instead of the previously supported | |
| break-before-make reauthentication, avoiding connectivity gaps during that | |
| procedure. As the new mechanism may fail with peers not supporting it (such | |
| as any previous strongSwan release) it must be explicitly enabled using | |
| the charon.make_before_break strongswan.conf option. | |
| - Support for "Signature Authentication in IKEv2" (RFC 7427) has been added. | |
| This allows the use of stronger hash algorithms for public key authentication. | |
| By default, signature schemes are chosen based on the strength of the | |
| signature key, but specific hash algorithms may be configured in leftauth. | |
| - Key types and hash algorithms specified in rightauth are now also checked | |
| against IKEv2 signature schemes. If such constraints are used for certificate | |
| chain validation in existing configurations, in particular with peers that | |
| don't support RFC 7427, it may be necessary to disable this feature with the | |
| charon.signature_authentication_constraints setting, because the signature | |
| scheme used in classic IKEv2 public key authentication may not be strong | |
| enough. | |
| - The new connmark plugin allows a host to bind conntrack flows to a specific | |
| CHILD_SA by applying and restoring the SA mark to conntrack entries. This | |
| allows a peer to handle multiple transport mode connections coming over the | |
| same NAT device for client-initiated flows. A common use case is to protect | |
| L2TP/IPsec, as supported by some systems. | |
| - The forecast plugin can forward broadcast and multicast messages between | |
| connected clients and a LAN. For CHILD_SA using unique marks, it sets up | |
| the required Netfilter rules and uses a multicast/broadcast listener that | |
| forwards such messages to all connected clients. This plugin is designed for | |
| Windows 7 IKEv2 clients, which announces its services over the tunnel if the | |
| negotiated IPsec policy allows it. | |
| - For the vici plugin a Python Egg has been added to allow Python applications | |
| to control or monitor the IKE daemon using the VICI interface, similar to the | |
| existing ruby gem. The Python library has been contributed by Björn Schuberg. | |
| - EAP server methods now can fulfill public key constraints, such as rightcert | |
| or rightca. Additionally, public key and signature constraints can be | |
| specified for EAP methods in the rightauth keyword. Currently the EAP-TLS and | |
| EAP-TTLS methods provide verification details to constraints checking. | |
| - Upgrade of the BLISS post-quantum signature algorithm to the improved BLISS-B | |
| variant. Can be used in conjunction with the SHA256, SHA384 and SHA512 hash | |
| algorithms with SHA512 being the default. | |
| - The IF-IMV 1.4 interface now makes the IP address of the TNC access requestor | |
| as seen by the TNC server available to all IMVs. This information can be | |
| forwarded to policy enforcement points (e.g. firewalls or routers). | |
| - The new mutual tnccs-20 plugin parameter activates mutual TNC measurements | |
| in PB-TNC half-duplex mode between two endpoints over either a PT-EAP or | |
| PT-TLS transport medium. | |
| strongswan-5.2.2 | |
| ---------------- | |
| - Fixed a denial-of-service vulnerability triggered by an IKEv2 Key Exchange | |
| payload that contains the Diffie-Hellman group 1025. This identifier was | |
| used internally for DH groups with custom generator and prime. Because | |
| these arguments are missing when creating DH objects based on the KE payload | |
| an invalid pointer dereference occurred. This allowed an attacker to crash | |
| the IKE daemon with a single IKE_SA_INIT message containing such a KE | |
| payload. The vulnerability has been registered as CVE-2014-9221. | |
| - The left/rightid options in ipsec.conf, or any other identity in strongSwan, | |
| now accept prefixes to enforce an explicit type, such as email: or fqdn:. | |
| Note that no conversion is done for the remaining string, refer to | |
| ipsec.conf(5) for details. | |
| - The post-quantum Bimodal Lattice Signature Scheme (BLISS) can be used as | |
| an IKEv2 public key authentication method. The pki tool offers full support | |
| for the generation of BLISS key pairs and certificates. | |
| - Fixed mapping of integrity algorithms negotiated for AH via IKEv1. This could | |
| cause interoperability issues when connecting to older versions of charon. | |
| strongswan-5.2.1 | |
| ---------------- | |
| - The new charon-systemd IKE daemon implements an IKE daemon tailored for use | |
| with systemd. It avoids the dependency on ipsec starter and uses swanctl | |
| as configuration backend, building a simple and lightweight solution. It | |
| supports native systemd journal logging. | |
| - Support for IKEv2 fragmentation as per RFC 7383 has been added. Like IKEv1 | |
| fragmentation it can be enabled by setting fragmentation=yes in ipsec.conf. | |
| - Support of the TCG TNC IF-M Attribute Segmentation specification proposal. | |
| All attributes can be segmented. Additionally TCG/SWID Tag, TCG/SWID Tag ID | |
| and IETF/Installed Packages attributes can be processed incrementally on a | |
| per segment basis. | |
| - The new ext-auth plugin calls an external script to implement custom IKE_SA | |
| authorization logic, courtesy of Vyronas Tsingaras. | |
| - For the vici plugin a ruby gem has been added to allow ruby applications | |
| to control or monitor the IKE daemon. The vici documentation has been updated | |
| to include a description of the available operations and some simple examples | |
| using both the libvici C interface and the ruby gem. | |
| strongswan-5.2.0 | |
| ---------------- | |
| - strongSwan has been ported to the Windows platform. Using a MinGW toolchain, | |
| many parts of the strongSwan codebase run natively on Windows 7 / 2008 R2 | |
| and newer releases. charon-svc implements a Windows IKE service based on | |
| libcharon, the kernel-iph and kernel-wfp plugins act as networking and IPsec | |
| backend on the Windows platform. socket-win provides a native IKE socket | |
| implementation, while winhttp fetches CRL and OCSP information using the | |
| WinHTTP API. | |
| - The new vici plugin provides a Versatile IKE Configuration Interface for | |
| charon. Using the stable IPC interface, external applications can configure, | |
| control and monitor the IKE daemon. Instead of scripting the ipsec tool | |
| and generating ipsec.conf, third party applications can use the new interface | |
| for more control and better reliability. | |
| - Built upon the libvici client library, swanctl implements the first user of | |
| the VICI interface. Together with a swanctl.conf configuration file, | |
| connections can be defined, loaded and managed. swanctl provides a portable, | |
| complete IKE configuration and control interface for the command line. | |
| The first six swanctl example scenarios have been added. | |
| - The SWID IMV implements a JSON-based REST API which allows the exchange | |
| of SWID tags and Software IDs with the strongTNC policy manager. | |
| - The SWID IMC can extract all installed packages from the dpkg (Debian, | |
| Ubuntu, Linux Mint etc.), rpm (Fedora, RedHat, OpenSUSE, etc.), or | |
| pacman (Arch Linux, Manjaro, etc.) package managers, respectively, using the | |
| swidGenerator (https://github.com/strongswan/swidGenerator) which generates | |
| SWID tags according to the new ISO/IEC 19770-2:2014 standard. | |
| - All IMVs now share the access requestor ID, device ID and product info | |
| of an access requestor via a common imv_session object. | |
| - The Attestation IMC/IMV pair supports the IMA-NG measurement format | |
| introduced with the Linux 3.13 kernel. | |
| - The aikgen tool generates an Attestation Identity Key bound to a TPM. | |
| - Implemented the PT-EAP transport protocol (RFC 7171) for Trusted Network | |
| Connect. | |
| - The ipsec.conf replay_window option defines connection specific IPsec replay | |
| windows. Original patch courtesy of Zheng Zhong and Christophe Gouault from | |
| 6Wind. | |
| strongswan-5.1.3 | |
| ---------------- | |
| - Fixed an authentication bypass vulnerability triggered by rekeying an | |
| unestablished IKEv2 SA while it gets actively initiated. This allowed an | |
| attacker to trick a peer's IKE_SA state to established, without the need to | |
| provide any valid authentication credentials. The vulnerability has been | |
| registered as CVE-2014-2338. | |
| - The acert plugin evaluates X.509 Attribute Certificates. Group membership | |
| information encoded as strings can be used to fulfill authorization checks | |
| defined with the rightgroups option. Attribute Certificates can be loaded | |
| locally or get exchanged in IKEv2 certificate payloads. | |
| - The pki command gained support to generate X.509 Attribute Certificates | |
| using the --acert subcommand, while the --print command supports the ac type. | |
| The openac utility has been removed in favor of the new pki functionality. | |
| - The libtls TLS 1.2 implementation as used by EAP-(T)TLS and other protocols | |
| has been extended by AEAD mode support, currently limited to AES-GCM. | |
| strongswan-5.1.2 | |
| ---------------- | |
| - A new default configuration file layout is introduced. The new default | |
| strongswan.conf file mainly includes config snippets from the strongswan.d | |
| and strongswan.d/charon directories (the latter containing snippets for all | |
| plugins). The snippets, with commented defaults, are automatically | |
| generated and installed, if they don't exist yet. They are also installed | |
| in $prefix/share/strongswan/templates so existing files can be compared to | |
| the current defaults. | |
| - As an alternative to the non-extensible charon.load setting, the plugins | |
| to load in charon (and optionally other applications) can now be determined | |
| via the charon.plugins.<name>.load setting for each plugin (enabled in the | |
| new default strongswan.conf file via the charon.load_modular option). | |
| The load setting optionally takes a numeric priority value that allows | |
| reordering the plugins (otherwise the default plugin order is preserved). | |
| - All strongswan.conf settings that were formerly defined in library specific | |
| "global" sections are now application specific (e.g. settings for plugins in | |
| libstrongswan.plugins can now be set only for charon in charon.plugins). | |
| The old options are still supported, which now allows to define defaults for | |
| all applications in the libstrongswan section. | |
| - The ntru libstrongswan plugin supports NTRUEncrypt as a post-quantum | |
| computer IKE key exchange mechanism. The implementation is based on the | |
| ntru-crypto library from the NTRUOpenSourceProject. The supported security | |
| strengths are ntru112, ntru128, ntru192, and ntru256. Since the private DH | |
| group IDs 1030..1033 have been assigned, the strongSwan Vendor ID must be | |
| sent (charon.send_vendor_id = yes) in order to use NTRU. | |
| - Defined a TPMRA remote attestation workitem and added support for it to the | |
| Attestation IMV. | |
| - Compatibility issues between IPComp (compress=yes) and leftfirewall=yes as | |
| well as multiple subnets in left|rightsubnet have been fixed. | |
| - When enabling its "session" strongswan.conf option, the xauth-pam plugin opens | |
| and closes a PAM session for each established IKE_SA. Patch courtesy of | |
| Andrea Bonomi. | |
| - The strongSwan unit testing framework has been rewritten without the "check" | |
| dependency for improved flexibility and portability. It now properly supports | |
| multi-threaded and memory leak testing and brings a bunch of new test cases. | |
| strongswan-5.1.1 | |
| ---------------- | |
| - Fixed a denial-of-service vulnerability and potential authorization bypass | |
| triggered by a crafted ID_DER_ASN1_DN ID payload. The cause is an insufficient | |
| length check when comparing such identities. The vulnerability has been | |
| registered as CVE-2013-6075. | |
| - Fixed a denial-of-service vulnerability triggered by a crafted IKEv1 | |
| fragmentation payload. The cause is a NULL pointer dereference. The | |
| vulnerability has been registered as CVE-2013-6076. | |
| - The lean stand-alone pt-tls-client can set up a RFC 6876 PT-TLS session | |
| with a strongSwan policy enforcement point which uses the tnc-pdp charon | |
| plugin. | |
| - The new TCG TNC SWID IMC/IMV pair supports targeted SWID requests for either | |
| full SWID Tag or concise SWID Tag ID inventories. | |
| - The XAuth backend in eap-radius now supports multiple XAuth exchanges for | |
| different credential types and display messages. All user input gets | |
| concatenated and verified with a single User-Password RADIUS attribute on | |
| the AAA. With an AAA supporting it, one for example can implement | |
| Password+Token authentication with proper dialogs on iOS and OS X clients. | |
| - charon supports IKEv1 Mode Config exchange in push mode. The ipsec.conf | |
| modeconfig=push option enables it for both client and server, the same way | |
| as pluto used it. | |
| - Using the "ah" ipsec.conf keyword on both IKEv1 and IKEv2 connections, | |
| charon can negotiate and install Security Associations integrity-protected by | |
| the Authentication Header protocol. Supported are plain AH(+IPComp) SAs only, | |
| but not the deprecated RFC2401 style ESP+AH bundles. | |
| - The generation of initialization vectors for IKE and ESP (when using libipsec) | |
| is now modularized and IVs for e.g. AES-GCM are now correctly allocated | |
| sequentially, while other algorithms like AES-CBC still use random IVs. | |
| - The left and right options in ipsec.conf can take multiple address ranges | |
| and subnets. This allows connection matching against a larger set of | |
| addresses, for example to use a different connection for clients connecting | |
| from a internal network. | |
| - For all those who have a queasy feeling about the NIST elliptic curve set, | |
| the Brainpool curves introduced for use with IKE by RFC 6932 might be a | |
| more trustworthy alternative. | |
| - The kernel-libipsec userland IPsec backend now supports usage statistics, | |
| volume based rekeying and accepts ESPv3 style TFC padded packets. | |
| - With two new strongswan.conf options fwmarks can be used to implement | |
| host-to-host tunnels with kernel-libipsec. | |
| - load-tester supports transport mode connections and more complex traffic | |
| selectors, including such using unique ports for each tunnel. | |
| - The new dnscert plugin provides support for authentication via CERT RRs that | |
| are protected via DNSSEC. The plugin was created by Ruslan N. Marchenko. | |
| - The eap-radius plugin supports forwarding of several Cisco Unity specific | |
| RADIUS attributes in corresponding configuration payloads. | |
| - Database transactions are now abstracted and implemented by the two backends. | |
| If you use MySQL make sure all tables use the InnoDB engine. | |
| - libstrongswan now can provide an experimental custom implementation of the | |
| printf family functions based on klibc if neither Vstr nor glibc style printf | |
| hooks are available. This can avoid the Vstr dependency on some systems at | |
| the cost of slower and less complete printf functions. | |
| strongswan-5.1.0 | |
| ---------------- | |
| - Fixed a denial-of-service vulnerability triggered by specific XAuth usernames | |
| and EAP identities (since 5.0.3), and PEM files (since 4.1.11). The crash | |
| was caused by insufficient error handling in the is_asn1() function. | |
| The vulnerability has been registered as CVE-2013-5018. | |
| - The new charon-cmd command line IKE client can establish road warrior | |
| connections using IKEv1 or IKEv2 with different authentication profiles. | |
| It does not depend on any configuration files and can be configured using a | |
| few simple command line options. | |
| - The kernel-pfroute networking backend has been greatly improved. It now | |
| can install virtual IPs on TUN devices on OS X and FreeBSD, allowing these | |
| systems to act as a client in common road warrior scenarios. | |
| - The new kernel-libipsec plugin uses TUN devices and libipsec to provide IPsec | |
| processing in userland on Linux, FreeBSD and Mac OS X. | |
| - The eap-radius plugin can now serve as an XAuth backend called xauth-radius, | |
| directly verifying XAuth credentials using RADIUS User-Name/User-Password | |
| attributes. This is more efficient than the existing xauth-eap+eap-radius | |
| combination, and allows RADIUS servers without EAP support to act as AAA | |
| backend for IKEv1. | |
| - The new osx-attr plugin installs configuration attributes (currently DNS | |
| servers) via SystemConfiguration on Mac OS X. The keychain plugin provides | |
| certificates from the OS X keychain service. | |
| - The sshkey plugin parses SSH public keys, which, together with the --agent | |
| option for charon-cmd, allows the use of ssh-agent for authentication. | |
| To configure SSH keys in ipsec.conf the left|rightrsasigkey options are | |
| replaced with left|rightsigkey, which now take public keys in one of three | |
| formats: SSH (RFC 4253, ssh: prefix), DNSKEY (RFC 3110, dns: prefix), and | |
| PKCS#1 (the default, no prefix). | |
| - Extraction of certificates and private keys from PKCS#12 files is now provided | |
| by the new pkcs12 plugin or the openssl plugin. charon-cmd (--p12) as well | |
| as charon (via P12 token in ipsec.secrets) can make use of this. | |
| - IKEv2 can now negotiate transport mode and IPComp in NAT situations. | |
| - IKEv2 exchange initiators now properly close an established IKE or CHILD_SA | |
| on error conditions using an additional exchange, keeping state in sync | |
| between peers. | |
| - Using a SQL database interface a Trusted Network Connect (TNC) Policy Manager | |
| can generate specific measurement workitems for an arbitrary number of | |
| Integrity Measurement Verifiers (IMVs) based on the history of the VPN user | |
| and/or device. | |
| - Several core classes in libstrongswan are now tested with unit tests. These | |
| can be enabled with --enable-unit-tests and run with 'make check'. Coverage | |
| reports can be generated with --enable-coverage and 'make coverage' (this | |
| disables any optimization, so it should not be enabled when building | |
| production releases). | |
| - The leak-detective developer tool has been greatly improved. It works much | |
| faster/stabler with multiple threads, does not use deprecated malloc hooks | |
| anymore and has been ported to OS X. | |
| - chunk_hash() is now based on SipHash-2-4 with a random key. This provides | |
| better distribution and prevents hash flooding attacks when used with | |
| hashtables. | |
| - All default plugins implement the get_features() method to define features | |
| and their dependencies. The plugin loader has been improved, so that plugins | |
| in a custom load statement can be ordered freely or to express preferences | |
| without being affected by dependencies between plugin features. | |
| - A centralized thread can take care for watching multiple file descriptors | |
| concurrently. This removes the need for a dedicated listener threads in | |
| various plugins. The number of "reserved" threads for such tasks has been | |
| reduced to about five, depending on the plugin configuration. | |
| - Plugins that can be controlled by a UNIX socket IPC mechanism gained network | |
| transparency. Third party applications querying these plugins now can use | |
| TCP connections from a different host. | |
| - libipsec now supports AES-GCM. | |
| strongswan-5.0.4 | |
| ---------------- | |
| - Fixed a security vulnerability in the openssl plugin which was reported by | |
| Kevin Wojtysiak. The vulnerability has been registered as CVE-2013-2944. | |
| Before the fix, if the openssl plugin's ECDSA signature verification was used, | |
| due to a misinterpretation of the error code returned by the OpenSSL | |
| ECDSA_verify() function, an empty or zeroed signature was accepted as a | |
| legitimate one. | |
| - The handling of a couple of other non-security relevant openssl return codes | |
| was fixed as well. | |
| - The tnc_ifmap plugin now publishes virtual IPv4 and IPv6 addresses via its | |
| TCG TNC IF-MAP 2.1 interface. | |
| - The charon.initiator_only option causes charon to ignore IKE initiation | |
| requests. | |
| - The openssl plugin can now use the openssl-fips library. | |
| strongswan-5.0.3 | |
| ---------------- | |
| - The new ipseckey plugin enables authentication based on trustworthy public | |
| keys stored as IPSECKEY resource records in the DNS and protected by DNSSEC. | |
| To do so it uses a DNSSEC enabled resolver, like the one provided by the new | |
| unbound plugin, which is based on libldns and libunbound. Both plugins were | |
| created by Reto Guadagnini. | |
| - Implemented the TCG TNC IF-IMV 1.4 draft making access requestor identities | |
| available to an IMV. The OS IMV stores the AR identity together with the | |
| device ID in the attest database. | |
| - The openssl plugin now uses the AES-NI accelerated version of AES-GCM | |
| if the hardware supports it. | |
| - The eap-radius plugin can now assign virtual IPs to IKE clients using the | |
| Framed-IP-Address attribute by using the "%radius" named pool in the | |
| rightsourceip ipsec.conf option. Cisco Banner attributes are forwarded to | |
| Unity-capable IKEv1 clients during mode config. charon now sends Interim | |
| Accounting updates if requested by the RADIUS server, reports | |
| sent/received packets in Accounting messages, and adds a Terminate-Cause | |
| to Accounting-Stops. | |
| - The recently introduced "ipsec listcounters" command can report connection | |
| specific counters by passing a connection name, and global or connection | |
| counters can be reset by the "ipsec resetcounters" command. | |
| - The strongSwan libpttls library provides an experimental implementation of | |
| PT-TLS (RFC 6876), a Posture Transport Protocol over TLS. | |
| - The charon systime-fix plugin can disable certificate lifetime checks on | |
| embedded systems if the system time is obviously out of sync after bootup. | |
| Certificates lifetimes get checked once the system time gets sane, closing | |
| or reauthenticating connections using expired certificates. | |
| - The "ikedscp" ipsec.conf option can set DiffServ code points on outgoing | |
| IKE packets. | |
| - The new xauth-noauth plugin allows to use basic RSA or PSK authentication with | |
| clients that cannot be configured without XAuth authentication. The plugin | |
| simply concludes the XAuth exchange successfully without actually performing | |
| any authentication. Therefore, to use this backend it has to be selected | |
| explicitly with rightauth2=xauth-noauth. | |
| - The new charon-tkm IKEv2 daemon delegates security critical operations to a | |
| separate process. This has the benefit that the network facing daemon has no | |
| knowledge of keying material used to protect child SAs. Thus subverting | |
| charon-tkm does not result in the compromise of cryptographic keys. | |
| The extracted functionality has been implemented from scratch in a minimal TCB | |
| (trusted computing base) in the Ada programming language. Further information | |
| can be found at http://www.codelabs.ch/tkm/. | |
| strongswan-5.0.2 | |
| ---------------- | |
| - Implemented all IETF Standard PA-TNC attributes and an OS IMC/IMV | |
| pair using them to transfer operating system information. | |
| - The new "ipsec listcounters" command prints a list of global counter values | |
| about received and sent IKE messages and rekeyings. | |
| - A new lookip plugin can perform fast lookup of tunnel information using a | |
| clients virtual IP and can send notifications about established or deleted | |
| tunnels. The "ipsec lookip" command can be used to query such information | |
| or receive notifications. | |
| - The new error-notify plugin catches some common error conditions and allows | |
| an external application to receive notifications for them over a UNIX socket. | |
| - IKE proposals can now use a PRF algorithm different to that defined for | |
| integrity protection. If an algorithm with a "prf" prefix is defined | |
| explicitly (such as prfsha1 or prfsha256), no implicit PRF algorithm based on | |
| the integrity algorithm is added to the proposal. | |
| - The pkcs11 plugin can now load leftcert certificates from a smartcard for a | |
| specific ipsec.conf conn section and cacert CA certificates for a specific ca | |
| section. | |
| - The load-tester plugin gained additional options for certificate generation | |
| and can load keys and multiple CA certificates from external files. It can | |
| install a dedicated outer IP address for each tunnel and tunnel initiation | |
| batches can be triggered and monitored externally using the | |
| "ipsec load-tester" tool. | |
| - PKCS#7 container parsing has been modularized, and the openssl plugin | |
| gained an alternative implementation to decrypt and verify such files. | |
| In contrast to our own DER parser, OpenSSL can handle BER files, which is | |
| required for interoperability of our scepclient with EJBCA. | |
| - Support for the proprietary IKEv1 fragmentation extension has been added. | |
| Fragments are always handled on receipt but only sent if supported by the peer | |
| and if enabled with the new fragmentation ipsec.conf option. | |
| - IKEv1 in charon can now parse certificates received in PKCS#7 containers and | |
| supports NAT traversal as used by Windows clients. Patches courtesy of | |
| Volker Rümelin. | |
| - The new rdrand plugin provides a high quality / high performance random | |
| source using the Intel rdrand instruction found on Ivy Bridge processors. | |
| - The integration test environment was updated and now uses KVM and reproducible | |
| guest images based on Debian. | |
| strongswan-5.0.1 | |
| ---------------- | |
| - Introduced the sending of the standard IETF Assessment Result | |
| PA-TNC attribute by all strongSwan Integrity Measurement Verifiers. | |
| - Extended PTS Attestation IMC/IMV pair to provide full evidence of | |
| the Linux IMA measurement process. All pertinent file information | |
| of a Linux OS can be collected and stored in an SQL database. | |
| - The PA-TNC and PB-TNC protocols can now process huge data payloads | |
| >64 kB by distributing PA-TNC attributes over multiple PA-TNC messages | |
| and these messages over several PB-TNC batches. As long as no | |
| consolidated recommandation from all IMVs can be obtained, the TNC | |
| server requests more client data by sending an empty SDATA batch. | |
| - The rightgroups2 ipsec.conf option can require group membership during | |
| a second authentication round, for example during XAuth authentication | |
| against a RADIUS server. | |
| - The xauth-pam backend can authenticate IKEv1 XAuth and Hybrid authenticated | |
| clients against any PAM service. The IKEv2 eap-gtc plugin does not use | |
| PAM directly anymore, but can use any XAuth backend to verify credentials, | |
| including xauth-pam. | |
| - The new unity plugin brings support for some parts of the IKEv1 Cisco Unity | |
| Extension. As client, charon narrows traffic selectors to the received | |
| Split-Include attributes and automatically installs IPsec bypass policies | |
| for received Local-LAN attributes. As server, charon sends Split-Include | |
| attributes for leftsubnet definitions containing multiple subnets to Unity- | |
| aware clients. | |
| - An EAP-Nak payload is returned by clients if the gateway requests an EAP | |
| method that the client does not support. Clients can also request a specific | |
| EAP method by configuring that method with leftauth. | |
| - The eap-dynamic plugin handles EAP-Nak payloads returned by clients and uses | |
| these to select a different EAP method supported/requested by the client. | |
| The plugin initially requests the first registered method or the first method | |
| configured with charon.plugins.eap-dynamic.preferred. | |
| - The new left/rightdns options specify connection specific DNS servers to | |
| request/respond in IKEv2 configuration payloads or IKEv2 mode config. leftdns | |
| can be any (comma separated) combination of %config4 and %config6 to request | |
| multiple servers, both for IPv4 and IPv6. rightdns takes a list of DNS server | |
| IP addresses to return. | |
| - The left/rightsourceip options now accept multiple addresses or pools. | |
| leftsourceip can be any (comma separated) combination of %config4, %config6 | |
| or fixed IP addresses to request. rightsourceip accepts multiple explicitly | |
| specified or referenced named pools. | |
| - Multiple connections can now share a single address pool when they use the | |
| same definition in one of the rightsourceip pools. | |
| - The options charon.interfaces_ignore and charon.interfaces_use allow one to | |
| configure the network interfaces used by the daemon. | |
| - The kernel-netlink plugin supports the charon.install_virtual_ip_on option, | |
| which specifies the interface on which virtual IP addresses will be installed. | |
| If it is not specified the current behavior of using the outbound interface | |
| is preserved. | |
| - The kernel-netlink plugin tries to keep the current source address when | |
| looking for valid routes to reach other hosts. | |
| - The autotools build has been migrated to use a config.h header. strongSwan | |
| development headers will get installed during "make install" if | |
| --with-dev-headers has been passed to ./configure. | |
| - All crypto primitives gained return values for most operations, allowing | |
| crypto backends to fail, for example when using hardware accelerators. | |
| strongswan-5.0.0 | |
| ---------------- | |
| - The charon IKE daemon gained experimental support for the IKEv1 protocol. | |
| Pluto has been removed from the 5.x series, and unless strongSwan is | |
| configured with --disable-ikev1 or --disable-ikev2, charon handles both | |
| keying protocols. The feature-set of IKEv1 in charon is almost on par with | |
| pluto, but currently does not support AH or bundled AH+ESP SAs. Beside | |
| RSA/ECDSA, PSK and XAuth, charon also supports the Hybrid authentication | |
| mode. Informations for interoperability and migration is available at | |
| http://wiki.strongswan.org/projects/strongswan/wiki/CharonPlutoIKEv1. | |
| - Charon's bus_t has been refactored so that loggers and other listeners are | |
| now handled separately. The single lock was previously cause for deadlocks | |
| if extensive listeners, such as the one provided by the updown plugin, wanted | |
| to acquire locks that were held by other threads which in turn tried to log | |
| messages, and thus were waiting to acquire the same lock currently held by | |
| the thread calling the listener. | |
| The implemented changes also allow the use of a read/write-lock for the | |
| loggers which increases performance if multiple loggers are registered. | |
| Besides several interface changes this last bit also changes the semantics | |
| for loggers as these may now be called by multiple threads at the same time. | |
| - Source routes are reinstalled if interfaces are reactivated or IP addresses | |
| reappear. | |
| - The thread pool (processor_t) now has more control over the lifecycle of | |
| a job (see job.h for details). In particular, it now controls the destruction | |
| of jobs after execution and the cancellation of jobs during shutdown. Due to | |
| these changes the requeueing feature, previously available to callback_job_t | |
| only, is now available to all jobs (in addition to a new rescheduling | |
| feature). | |
| - In addition to trustchain key strength definitions for different public key | |
| systems, the rightauth option now takes a list of signature hash algorithms | |
| considered save for trustchain validation. For example, the setting | |
| rightauth=rsa-2048-ecdsa-256-sha256-sha384-sha512 requires a trustchain | |
| that uses at least RSA-2048 or ECDSA-256 keys and certificate signatures | |
| using SHA-256 or better. | |
| strongswan-4.6.4 | |
| ---------------- | |
| - Fixed a security vulnerability in the gmp plugin. If this plugin was used | |
| for RSA signature verification an empty or zeroed signature was handled as | |
| a legitimate one. | |
| - Fixed several issues with reauthentication and address updates. | |
| strongswan-4.6.3 | |
| ---------------- | |
| - The tnc-pdp plugin implements a RADIUS server interface allowing | |
| a strongSwan TNC server to act as a Policy Decision Point. | |
| - The eap-radius authentication backend enforces Session-Timeout attributes | |
| using RFC4478 repeated authentication and acts upon RADIUS Dynamic | |
| Authorization extensions, RFC 5176. Currently supported are disconnect | |
| requests and CoA messages containing a Session-Timeout. | |
| - The eap-radius plugin can forward arbitrary RADIUS attributes from and to | |
| clients using custom IKEv2 notify payloads. The new radattr plugin reads | |
| attributes to include from files and prints received attributes to the | |
| console. | |
| - Added support for untruncated MD5 and SHA1 HMACs in ESP as used in | |
| RFC 4595. | |
| - The cmac plugin implements the AES-CMAC-96 and AES-CMAC-PRF-128 algorithms | |
| as defined in RFC 4494 and RFC 4615, respectively. | |
| - The resolve plugin automatically installs nameservers via resolvconf(8), | |
| if it is installed, instead of modifying /etc/resolv.conf directly. | |
| - The IKEv2 charon daemon supports now raw RSA public keys in RFC 3110 | |
| DNSKEY and PKCS#1 file format. | |
| strongswan-4.6.2 | |
| ---------------- | |
| - Upgraded the TCG IF-IMC and IF-IMV C API to the upcoming version 1.3 | |
| which supports IF-TNCCS 2.0 long message types, the exclusive flags | |
| and multiple IMC/IMV IDs. Both the TNC Client and Server as well as | |
| the "Test", "Scanner", and "Attestation" IMC/IMV pairs were updated. | |
| - Fully implemented the "TCG Attestation PTS Protocol: Binding to IF-M" | |
| standard (TLV-based messages only). TPM-based remote attestation of | |
| Linux IMA (Integrity Measurement Architecture) possible. Measurement | |
| reference values are automatically stored in an SQLite database. | |
| - The EAP-RADIUS authentication backend supports RADIUS accounting. It sends | |
| start/stop messages containing Username, Framed-IP and Input/Output-Octets | |
| attributes and has been tested against FreeRADIUS and Microsoft NPS. | |
| - Added support for PKCS#8 encoded private keys via the libstrongswan | |
| pkcs8 plugin. This is the default format used by some OpenSSL tools since | |
| version 1.0.0 (e.g. openssl req with -keyout). | |
| - Added session resumption support to the strongSwan TLS stack. | |
| strongswan-4.6.1 | |
| ---------------- | |
| - Because of changing checksums before and after installation which caused | |
| the integrity tests to fail we avoided directly linking libsimaka, libtls and | |
| libtnccs to those libcharon plugins which make use of these dynamic libraries. | |
| Instead we linked the libraries to the charon daemon. Unfortunately Ubuntu | |
| 11.10 activated the --as-needed ld option which discards explicit links | |
| to dynamic libraries that are not actually used by the charon daemon itself, | |
| thus causing failures during the loading of the plugins which depend on these | |
| libraries for resolving external symbols. | |
| - Therefore our approach of computing integrity checksums for plugins had to be | |
| changed radically by moving the hash generation from the compilation to the | |
| post-installation phase. | |
| strongswan-4.6.0 | |
| ---------------- | |
| - The new libstrongswan certexpire plugin collects expiration information of | |
| all used certificates and exports them to CSV files. It either directly | |
| exports them or uses cron style scheduling for batch exports. | |
| - starter passes unresolved hostnames to charon, allowing it to do name | |
| resolution not before the connection attempt. This is especially useful with | |
| connections between hosts using dynamic IP addresses. Thanks to Mirko Parthey | |
| for the initial patch. | |
| - The android plugin can now be used without the Android frontend patch and | |
| provides DNS server registration and logging to logcat. | |
| - Pluto and starter (plus stroke and whack) have been ported to Android. | |
| - Support for ECDSA private and public key operations has been added to the | |
| pkcs11 plugin. The plugin now also provides DH and ECDH via PKCS#11 and can | |
| use tokens as random number generators (RNG). By default only private key | |
| operations are enabled, more advanced features have to be enabled by their | |
| option in strongswan.conf. This also applies to public key operations (even | |
| for keys not stored on the token) which were enabled by default before. | |
| - The libstrongswan plugin system now supports detailed plugin dependencies. | |
| Many plugins have been extended to export its capabilities and requirements. | |
| This allows the plugin loader to resolve plugin loading order automatically, | |
| and in future releases, to dynamically load the required features on demand. | |
| Existing third party plugins are source (but not binary) compatible if they | |
| properly initialize the new get_features() plugin function to NULL. | |
| - The tnc-ifmap plugin implements a TNC IF-MAP 2.0 client which can deliver | |
| metadata about IKE_SAs via a SOAP interface to a MAP server. The tnc-ifmap | |
| plugin requires the Apache Axis2/C library. | |
| strongswan-4.5.3 | |
| ---------------- | |
| - Our private libraries (e.g. libstrongswan) are not installed directly in | |
| prefix/lib anymore. Instead a subdirectory is used (prefix/lib/ipsec/ by | |
| default). The plugins directory is also moved from libexec/ipsec/ to that | |
| directory. | |
| - The dynamic IMC/IMV libraries were moved from the plugins directory to | |
| a new imcvs directory in the prefix/lib/ipsec/ subdirectory. | |
| - Job priorities were introduced to prevent thread starvation caused by too | |
| many threads handling blocking operations (such as CRL fetching). Refer to | |
| strongswan.conf(5) for details. | |
| - Two new strongswan.conf options allow to fine-tune performance on IKEv2 | |
| gateways by dropping IKE_SA_INIT requests on high load. | |
| - IKEv2 charon daemon supports start PASS and DROP shunt policies | |
| preventing traffic to go through IPsec connections. Installation of the | |
| shunt policies either via the XFRM netfilter or PFKEYv2 IPsec kernel | |
| interfaces. | |
| - The history of policies installed in the kernel is now tracked so that e.g. | |
| trap policies are correctly updated when reauthenticated SAs are terminated. | |
| - IMC/IMV Scanner pair implementing the RFC 5792 PA-TNC (IF-M) protocol. | |
| Using "netstat -l" the IMC scans open listening ports on the TNC client | |
| and sends a port list to the IMV which based on a port policy decides if | |
| the client is admitted to the network. | |
| (--enable-imc-scanner/--enable-imv-scanner). | |
| - IMC/IMV Test pair implementing the RFC 5792 PA-TNC (IF-M) protocol. | |
| (--enable-imc-test/--enable-imv-test). | |
| - The IKEv2 close action does not use the same value as the ipsec.conf dpdaction | |
| setting, but the value defined by its own closeaction keyword. The action | |
| is triggered if the remote peer closes a CHILD_SA unexpectedly. | |
| strongswan-4.5.2 | |
| ---------------- | |
| - The whitelist plugin for the IKEv2 daemon maintains an in-memory identity | |
| whitelist. Any connection attempt of peers not whitelisted will get rejected. | |
| The 'ipsec whitelist' utility provides a simple command line frontend for | |
| whitelist administration. | |
| - The duplicheck plugin provides a specialized form of duplicate checking, | |
| doing a liveness check on the old SA and optionally notify a third party | |
| application about detected duplicates. | |
| - The coupling plugin permanently couples two or more devices by limiting | |
| authentication to previously used certificates. | |
| - In the case that the peer config and child config don't have the same name | |
| (usually in SQL database defined connections), ipsec up|route <peer config> | |
| starts|routes all associated child configs and ipsec up|route <child config> | |
| only starts|routes the specific child config. | |
| - fixed the encoding and parsing of X.509 certificate policy statements (CPS). | |
| - Duncan Salerno contributed the eap-sim-pcsc plugin implementing a | |
| pcsc-lite based SIM card backend. | |
| - The eap-peap plugin implements the EAP PEAP protocol. Interoperates | |
| successfully with a FreeRADIUS server and Windows 7 Agile VPN clients. | |
| - The IKEv2 daemon charon rereads strongswan.conf on SIGHUP and instructs | |
| all plugins to reload. Currently only the eap-radius and the attr plugins | |
| support configuration reloading. | |
| - Added userland support to the IKEv2 daemon for Extended Sequence Numbers | |
| support coming with Linux 2.6.39. To enable ESN on a connection, add | |
| the 'esn' keyword to the proposal. The default proposal uses 32-bit sequence | |
| numbers only ('noesn'), and the same value is used if no ESN mode is | |
| specified. To negotiate ESN support with the peer, include both, e.g. | |
| esp=aes128-sha1-esn-noesn. | |
| - In addition to ESN, Linux 2.6.39 gained support for replay windows larger | |
| than 32 packets. The new global strongswan.conf option 'charon.replay_window' | |
| configures the size of the replay window, in packets. | |
| strongswan-4.5.1 | |
| ---------------- | |
| - Sansar Choinyambuu implemented the RFC 5793 Posture Broker Protocol (BP) | |
| compatible with Trusted Network Connect (TNC). The TNCCS 2.0 protocol | |
| requires the tnccs_20, tnc_imc and tnc_imv plugins but does not depend | |
| on the libtnc library. Any available IMV/IMC pairs conforming to the | |
| Trusted Computing Group's TNC-IF-IMV/IMC 1.2 interface specification | |
| can be loaded via /etc/tnc_config. | |
| - Re-implemented the TNCCS 1.1 protocol by using the tnc_imc and tnc_imv | |
| in place of the external libtnc library. | |
| - The tnccs_dynamic plugin loaded on a TNC server in addition to the | |
| tnccs_11 and tnccs_20 plugins, dynamically detects the IF-TNCCS | |
| protocol version used by a TNC client and invokes an instance of | |
| the corresponding protocol stack. | |
| - IKE and ESP proposals can now be stored in an SQL database using a | |
| new proposals table. The start_action field in the child_configs | |
| tables allows the automatic starting or routing of connections stored | |
| in an SQL database. | |
| - The new certificate_authorities and certificate_distribution_points | |
| tables make it possible to store CRL and OCSP Certificate Distribution | |
| points in an SQL database. | |
| - The new 'include' statement allows to recursively include other files in | |
| strongswan.conf. Existing sections and values are thereby extended and | |
| replaced, respectively. | |
| - Due to the changes in the parser for strongswan.conf, the configuration | |
| syntax for the attr plugin has changed. Previously, it was possible to | |
| specify multiple values of a specific attribute type by adding multiple | |
| key/value pairs with the same key (e.g. dns) to the plugins.attr section. | |
| Because values with the same key now replace previously defined values | |
| this is not possible anymore. As an alternative, multiple values can be | |
| specified by separating them with a comma (e.g. dns = 1.2.3.4, 2.3.4.5). | |
| - ipsec listalgs now appends (set in square brackets) to each crypto | |
| algorithm listed the plugin that registered the function. | |
| - Traffic Flow Confidentiality padding supported with Linux 2.6.38 can be used | |
| by the IKEv2 daemon. The ipsec.conf 'tfc' keyword pads all packets to a given | |
| boundary, the special value '%mtu' pads all packets to the path MTU. | |
| - The new af-alg plugin can use various crypto primitives of the Linux Crypto | |
| API using the AF_ALG interface introduced with 2.6.38. This removes the need | |
| for additional userland implementations of symmetric cipher, hash, hmac and | |
| xcbc algorithms. | |
| - The IKEv2 daemon supports the INITIAL_CONTACT notify as initiator and | |
| responder. The notify is sent when initiating configurations with a unique | |
| policy, set in ipsec.conf via the global 'uniqueids' option. | |
| - The conftest conformance testing framework enables the IKEv2 stack to perform | |
| many tests using a distinct tool and configuration frontend. Various hooks | |
| can alter reserved bits, flags, add custom notifies and proposals, reorder | |
| or drop messages and much more. It is enabled using the --enable-conftest | |
| ./configure switch. | |
| - The new libstrongswan constraints plugin provides advanced X.509 constraint | |
| checking. In addition to X.509 pathLen constraints, the plugin checks for | |
| nameConstraints and certificatePolicies, including policyMappings and | |
| policyConstraints. The x509 certificate plugin and the pki tool have been | |
| enhanced to support these extensions. The new left/rightcertpolicy ipsec.conf | |
| connection keywords take OIDs a peer certificate must have. | |
| - The left/rightauth ipsec.conf keywords accept values with a minimum strength | |
| for trustchain public keys in bits, such as rsa-2048 or ecdsa-256. | |
| - The revocation and x509 libstrongswan plugins and the pki tool gained basic | |
| support for delta CRLs. | |
| strongswan-4.5.0 | |
| ---------------- | |
| - IMPORTANT: the default keyexchange mode 'ike' is changing with release 4.5 | |
| from 'ikev1' to 'ikev2', thus commemorating the five year anniversary of the | |
| IKEv2 RFC 4306 and its mature successor RFC 5996. The time has definitively | |
| come for IKEv1 to go into retirement and to cede its place to the much more | |
| robust, powerful and versatile IKEv2 protocol! | |
| - Added new ctr, ccm and gcm plugins providing Counter, Counter with CBC-MAC | |
| and Galois/Counter Modes based on existing CBC implementations. These | |
| new plugins bring support for AES and Camellia Counter and CCM algorithms | |
| and the AES GCM algorithms for use in IKEv2. | |
| - The new pkcs11 plugin brings full Smartcard support to the IKEv2 daemon and | |
| the pki utility using one or more PKCS#11 libraries. It currently supports | |
| RSA private and public key operations and loads X.509 certificates from | |
| tokens. | |
| - Implemented a general purpose TLS stack based on crypto and credential | |
| primitives of libstrongswan. libtls supports TLS versions 1.0, 1.1 and 1.2, | |
| ECDHE-ECDSA/RSA, DHE-RSA and RSA key exchange algorithms and RSA/ECDSA based | |
| client authentication. | |
| - Based on libtls, the eap-tls plugin brings certificate based EAP | |
| authentication for client and server. It is compatible to Windows 7 IKEv2 | |
| Smartcard authentication and the OpenSSL based FreeRADIUS EAP-TLS backend. | |
| - Implemented the TNCCS 1.1 Trusted Network Connect protocol using the | |
| libtnc library on the strongSwan client and server side via the tnccs_11 | |
| plugin and optionally connecting to a TNC@FHH-enhanced FreeRADIUS AAA server. | |
| Depending on the resulting TNC Recommendation, strongSwan clients are granted | |
| access to a network behind a strongSwan gateway (allow), are put into a | |
| remediation zone (isolate) or are blocked (none), respectively. Any number | |
| of Integrity Measurement Collector/Verifier pairs can be attached | |
| via the tnc-imc and tnc-imv charon plugins. | |
| - The IKEv1 daemon pluto now uses the same kernel interfaces as the IKEv2 | |
| daemon charon. As a result of this, pluto now supports xfrm marks which | |
| were introduced in charon with 4.4.1. | |
| - Applets for Maemo 5 (Nokia) allow to easily configure and control IKEv2 | |
| based VPN connections with EAP authentication on supported devices. | |
| - The RADIUS plugin eap-radius now supports multiple RADIUS servers for | |
| redundant setups. Servers are selected by a defined priority, server load and | |
| availability. | |
| - The simple led plugin controls hardware LEDs through the Linux LED subsystem. | |
| It currently shows activity of the IKE daemon and is a good example how to | |
| implement a simple event listener. | |
| - Improved MOBIKE behavior in several corner cases, for instance, if the | |
| initial responder moves to a different address. | |
| - Fixed left-/rightnexthop option, which was broken since 4.4.0. | |
| - Fixed a bug not releasing a virtual IP address to a pool if the XAUTH | |
| identity was different from the IKE identity. | |
| - Fixed the alignment of ModeConfig messages on 4-byte boundaries in the | |
| case where the attributes are not a multiple of 4 bytes (e.g. Cisco's | |
| UNITY_BANNER). | |
| - Fixed the interoperability of the socket_raw and socket_default | |
| charon plugins. | |
| - Added man page for strongswan.conf | |
| strongswan-4.4.1 | |
| ---------------- | |
| - Support of xfrm marks in IPsec SAs and IPsec policies introduced | |
| with the Linux 2.6.34 kernel. For details see the example scenarios | |
| ikev2/nat-two-rw-mark, ikev2/rw-nat-mark-in-out and ikev2/net2net-psk-dscp. | |
| - The PLUTO_MARK_IN and PLUTO_ESP_ENC environment variables can be used | |
| in a user-specific updown script to set marks on inbound ESP or | |
| ESP_IN_UDP packets. | |
| - The openssl plugin now supports X.509 certificate and CRL functions. | |
| - OCSP/CRL checking in IKEv2 has been moved to the revocation plugin, enabled | |
| by default. Plase update manual load directives in strongswan.conf. | |
| - RFC3779 ipAddrBlock constraint checking has been moved to the addrblock | |
| plugin, disabled by default. Enable it and update manual load directives | |
| in strongswan.conf, if required. | |
| - The pki utility supports CRL generation using the --signcrl command. | |
| - The ipsec pki --self, --issue and --req commands now support output in | |
| PEM format using the --outform pem option. | |
| - The major refactoring of the IKEv1 Mode Config functionality now allows | |
| the transport and handling of any Mode Config attribute. | |
| - The RADIUS proxy plugin eap-radius now supports multiple servers. Configured | |
| servers are chosen randomly, with the option to prefer a specific server. | |
| Non-responding servers are degraded by the selection process. | |
| - The ipsec pool tool manages arbitrary configuration attributes stored | |
| in an SQL database. ipsec pool --help gives the details. | |
| - The new eap-simaka-sql plugin acts as a backend for EAP-SIM and EAP-AKA, | |
| reading triplets/quintuplets from an SQL database. | |
| - The High Availability plugin now supports a HA enabled in-memory address | |
| pool and Node reintegration without IKE_SA rekeying. The latter allows | |
| clients without IKE_SA rekeying support to keep connected during | |
| reintegration. Additionally, many other issues have been fixed in the ha | |
| plugin. | |
| - Fixed a potential remote code execution vulnerability resulting from | |
| the misuse of snprintf(). The vulnerability is exploitable by | |
| unauthenticated users. | |
| strongswan-4.4.0 | |
| ---------------- | |
| - The IKEv2 High Availability plugin has been integrated. It provides | |
| load sharing and failover capabilities in a cluster of currently two nodes, | |
| based on an extend ClusterIP kernel module. More information is available at | |
| http://wiki.strongswan.org/projects/strongswan/wiki/HighAvailability. | |
| The development of the High Availability functionality was sponsored by | |
| secunet Security Networks AG. | |
| - Added IKEv1 and IKEv2 configuration support for the AES-GMAC | |
| authentication-only ESP cipher. Our aes_gmac kernel patch or a Linux | |
| 2.6.34 kernel is required to make AES-GMAC available via the XFRM | |
| kernel interface. | |
| - Added support for Diffie-Hellman groups 22, 23 and 24 to the gmp, gcrypt | |
| and openssl plugins, usable by both pluto and charon. The new proposal | |
| keywords are modp1024s160, modp2048s224 and modp2048s256. Thanks to Joy Latten | |
| from IBM for his contribution. | |
| - The IKEv1 pluto daemon supports RAM-based virtual IP pools using | |
| the rightsourceip directive with a subnet from which addresses | |
| are allocated. | |
| - The ipsec pki --gen and --pub commands now allow the output of | |
| private and public keys in PEM format using the --outform pem | |
| command line option. | |
| - The new DHCP plugin queries virtual IP addresses for clients from a DHCP | |
| server using broadcasts, or a defined server using the | |
| charon.plugins.dhcp.server strongswan.conf option. DNS/WINS server information | |
| is additionally served to clients if the DHCP server provides such | |
| information. The plugin is used in ipsec.conf configurations having | |
| rightsourceip set to %dhcp. | |
| - A new plugin called farp fakes ARP responses for virtual IP addresses | |
| handed out to clients from the IKEv2 daemon charon. The plugin lets a | |
| road-warrior act as a client on the local LAN if it uses a virtual IP | |
| from the responders subnet, e.g. acquired using the DHCP plugin. | |
| - The existing IKEv2 socket implementations have been migrated to the | |
| socket-default and the socket-raw plugins. The new socket-dynamic plugin | |
| binds sockets dynamically to ports configured via the left-/rightikeport | |
| ipsec.conf connection parameters. | |
| - The android charon plugin stores received DNS server information as "net.dns" | |
| system properties, as used by the Android platform. | |
| strongswan-4.3.6 | |
| ---------------- | |
| - The IKEv2 daemon supports RFC 3779 IP address block constraints | |
| carried as a critical X.509v3 extension in the peer certificate. | |
| - The ipsec pool --add|del dns|nbns command manages DNS and NBNS name | |
| server entries that are sent via the IKEv1 Mode Config or IKEv2 | |
| Configuration Payload to remote clients. | |
| - The Camellia cipher can be used as an IKEv1 encryption algorithm. | |
| - The IKEv1 and IKEV2 daemons now check certificate path length constraints. | |
| - The new ipsec.conf conn option "inactivity" closes a CHILD_SA if no traffic | |
| was sent or received within the given interval. To close the complete IKE_SA | |
| if its only CHILD_SA was inactive, set the global strongswan.conf option | |
| "charon.inactivity_close_ike" to yes. | |
| - More detailed IKEv2 EAP payload information in debug output | |
| - IKEv2 EAP-SIM and EAP-AKA share joint libsimaka library | |
| - Added required userland changes for proper SHA256 and SHA384/512 in ESP that | |
| will be introduced with Linux 2.6.33. The "sha256"/"sha2_256" keyword now | |
| configures the kernel with 128 bit truncation, not the non-standard 96 | |
| bit truncation used by previous releases. To use the old 96 bit truncation | |
| scheme, the new "sha256_96" proposal keyword has been introduced. | |
| - Fixed IPComp in tunnel mode, stripping out the duplicated outer header. This | |
| change makes IPcomp tunnel mode connections incompatible with previous | |
| releases; disable compression on such tunnels. | |
| - Fixed BEET mode connections on recent kernels by installing SAs with | |
| appropriate traffic selectors, based on a patch by Michael Rossberg. | |
| - Using extensions (such as BEET mode) and crypto algorithms (such as twofish, | |
| serpent, sha256_96) allocated in the private use space now require that we | |
| know its meaning, i.e. we are talking to strongSwan. Use the new | |
| "charon.send_vendor_id" option in strongswan.conf to let the remote peer know | |
| this is the case. | |
| - Experimental support for draft-eronen-ipsec-ikev2-eap-auth, where the | |
| responder omits public key authentication in favor of a mutual authentication | |
| method. To enable EAP-only authentication, set rightauth=eap on the responder | |
| to rely only on the MSK constructed AUTH payload. This not-yet standardized | |
| extension requires the strongSwan vendor ID introduced above. | |
| - The IKEv1 daemon ignores the Juniper SRX notification type 40001, thus | |
| allowing interoperability. | |
| strongswan-4.3.5 | |
| ---------------- | |
| - The IKEv1 pluto daemon can now use SQL-based address pools to deal out | |
| virtual IP addresses as a Mode Config server. The pool capability has been | |
| migrated from charon's sql plugin to a new attr-sql plugin which is loaded | |
| by libstrongswan and which can be used by both daemons either with a SQLite | |
| or MySQL database and the corresponding plugin. | |
| - Plugin names have been streamlined: EAP plugins now have a dash after eap | |
| (e.g. eap-sim), as it is used with the --enable-eap-sim ./configure option. | |
| Plugin configuration sections in strongswan.conf now use the same name as the | |
| plugin itself (i.e. with a dash). Make sure to update "load" directives and | |
| the affected plugin sections in existing strongswan.conf files. | |
| - The private/public key parsing and encoding has been split up into | |
| separate pkcs1, pgp, pem and dnskey plugins. The public key implementation | |
| plugins gmp, gcrypt and openssl can all make use of them. | |
| - The EAP-AKA plugin can use different backends for USIM/quintuplet | |
| calculations, very similar to the EAP-SIM plugin. The existing 3GPP2 software | |
| implementation has been migrated to a separate plugin. | |
| - The IKEv2 daemon charon gained basic PGP support. It can use locally installed | |
| peer certificates and can issue signatures based on RSA private keys. | |
| - The new 'ipsec pki' tool provides a set of commands to maintain a public | |
| key infrastructure. It currently supports operations to create RSA and ECDSA | |
| private/public keys, calculate fingerprints and issue or verify certificates. | |
| - Charon uses a monotonic time source for statistics and job queueing, behaving | |
| correctly if the system time changes (e.g. when using NTP). | |
| - In addition to time based rekeying, charon supports IPsec SA lifetimes based | |
| on processed volume or number of packets. They new ipsec.conf paramaters | |
| 'lifetime' (an alias to 'keylife'), 'lifebytes' and 'lifepackets' handle | |
| SA timeouts, while the parameters 'margintime' (an alias to rekeymargin), | |
| 'marginbytes' and 'marginpackets' trigger the rekeying before a SA expires. | |
| The existing parameter 'rekeyfuzz' affects all margins. | |
| - If no CA/Gateway certificate is specified in the NetworkManager plugin, | |
| charon uses a set of trusted root certificates preinstalled by distributions. | |
| The directory containing CA certificates can be specified using the | |
| --with-nm-ca-dir=path configure option. | |
| - Fixed the encoding of the Email relative distinguished name in left|rightid | |
| statements. | |
| - Fixed the broken parsing of PKCS#7 wrapped certificates by the pluto daemon. | |
| - Fixed smartcard-based authentication in the pluto daemon which was broken by | |
| the ECDSA support introduced with the 4.3.2 release. | |
| - A patch contributed by Heiko Hund fixes mixed IPv6 in IPv4 and vice versa | |
| tunnels established with the IKEv1 pluto daemon. | |
| - The pluto daemon now uses the libstrongswan x509 plugin for certificates and | |
| CRls and the struct id type was replaced by identification_t used by charon | |
| and the libstrongswan library. | |
| strongswan-4.3.4 | |
| ---------------- | |
| - IKEv2 charon daemon ported to FreeBSD and Mac OS X. Installation details can | |
| be found on wiki.strongswan.org. | |
| - ipsec statusall shows the number of bytes transmitted and received over | |
| ESP connections configured by the IKEv2 charon daemon. | |
| - The IKEv2 charon daemon supports include files in ipsec.secrets. | |
| strongswan-4.3.3 | |
| ---------------- | |
| - The configuration option --enable-integrity-test plus the strongswan.conf | |
| option libstrongswan.integrity_test = yes activate integrity tests | |
| of the IKE daemons charon and pluto, libstrongswan and all loaded | |
| plugins. Thus dynamic library misconfigurations and non-malicious file | |
| manipulations can be reliably detected. | |
| - The new default setting libstrongswan.ecp_x_coordinate_only=yes allows | |
| IKEv1 interoperability with MS Windows using the ECP DH groups 19 and 20. | |
| - The IKEv1 pluto daemon now supports the AES-CCM and AES-GCM ESP | |
| authenticated encryption algorithms. | |
| - The IKEv1 pluto daemon now supports V4 OpenPGP keys. | |
| - The RDN parser vulnerability discovered by Orange Labs research team | |
| was not completely fixed in version 4.3.2. Some more modifications | |
| had to be applied to the asn1_length() function to make it robust. | |
| strongswan-4.3.2 | |
| ---------------- | |
| - The new gcrypt plugin provides symmetric cipher, hasher, RNG, Diffie-Hellman | |
| and RSA crypto primitives using the LGPL licensed GNU gcrypt library. | |
| - libstrongswan features an integrated crypto selftest framework for registered | |
| algorithms. The test-vector plugin provides a first set of test vectors and | |
| allows pluto and charon to rely on tested crypto algorithms. | |
| - pluto can now use all libstrongswan plugins with the exception of x509 and xcbc. | |
| Thanks to the openssl plugin, the ECP Diffie-Hellman groups 19, 20, 21, 25, and | |
| 26 as well as ECDSA-256, ECDSA-384, and ECDSA-521 authentication can be used | |
| with IKEv1. | |
| - Applying their fuzzing tool, the Orange Labs vulnerability research team found | |
| another two DoS vulnerabilities, one in the rather old ASN.1 parser of Relative | |
| Distinguished Names (RDNs) and a second one in the conversion of ASN.1 UTCTIME | |
| and GENERALIZEDTIME strings to a time_t value. | |
| strongswan-4.3.1 | |
| ---------------- | |
| - The nm plugin now passes DNS/NBNS server information to NetworkManager, | |
| allowing a gateway administrator to set DNS/NBNS configuration on clients | |
| dynamically. | |
| - The nm plugin also accepts CA certificates for gateway authentication. If | |
| a CA certificate is configured, strongSwan uses the entered gateway address | |
| as its idenitity, requiring the gateways certificate to contain the same as | |
| subjectAltName. This allows a gateway administrator to deploy the same | |
| certificates to Windows 7 and NetworkManager clients. | |
| - The command ipsec purgeike deletes IKEv2 SAs that don't have a CHILD SA. | |
| The command ipsec down <conn>{n} deletes CHILD SA instance n of connection | |
| <conn> whereas ipsec down <conn>{*} deletes all CHILD SA instances. | |
| The command ipsec down <conn>[n] deletes IKE SA instance n of connection | |
| <conn> plus dependent CHILD SAs whereas ipsec down <conn>[*] deletes all | |
| IKE SA instances of connection <conn>. | |
| - Fixed a regression introduced in 4.3.0 where EAP authentication calculated | |
| the AUTH payload incorrectly. Further, the EAP-MSCHAPv2 MSK key derivation | |
| has been updated to be compatible with the Windows 7 Release Candidate. | |
| - Refactored installation of triggering policies. Routed policies are handled | |
| outside of IKE_SAs to keep them installed in any case. A tunnel gets | |
| established only once, even if initiation is delayed due network outages. | |
| - Improved the handling of multiple acquire signals triggered by the kernel. | |
| - Fixed two DoS vulnerabilities in the charon daemon that were discovered by | |
| fuzzing techniques: 1) Sending a malformed IKE_SA_INIT request leaved an | |
| incomplete state which caused a null pointer dereference if a subsequent | |
| CREATE_CHILD_SA request was sent. 2) Sending an IKE_AUTH request with either | |
| a missing TSi or TSr payload caused a null pointer derefence because the | |
| checks for TSi and TSr were interchanged. The IKEv2 fuzzer used was | |
| developed by the Orange Labs vulnerability research team. The tool was | |
| initially written by Gabriel Campana and is now maintained by Laurent Butti. | |
| - Added support for AES counter mode in ESP in IKEv2 using the proposal | |
| keywords aes128ctr, aes192ctr and aes256ctr. | |
| - Further progress in refactoring pluto: Use of the curl and ldap plugins | |
| for fetching crls and OCSP. Use of the random plugin to get keying material | |
| from /dev/random or /dev/urandom. Use of the openssl plugin as an alternative | |
| to the aes, des, sha1, sha2, and md5 plugins. The blowfish, twofish, and | |
| serpent encryption plugins are now optional and are not enabled by default. | |
| strongswan-4.3.0 | |
| ---------------- | |
| - Support for the IKEv2 Multiple Authentication Exchanges extension (RFC4739). | |
| Initiators and responders can use several authentication rounds (e.g. RSA | |
| followed by EAP) to authenticate. The new ipsec.conf leftauth/rightauth and | |
| leftauth2/rightauth2 parameters define own authentication rounds or setup | |
| constraints for the remote peer. See the ipsec.conf man page for more detials. | |
| - If glibc printf hooks (register_printf_function) are not available, | |
| strongSwan can use the vstr string library to run on non-glibc systems. | |
| - The IKEv2 charon daemon can now configure the ESP CAMELLIA-CBC cipher | |
| (esp=camellia128|192|256). | |
| - Refactored the pluto and scepclient code to use basic functions (memory | |
| allocation, leak detective, chunk handling, printf_hooks, strongswan.conf | |
| attributes, ASN.1 parser, etc.) from the libstrongswan library. | |
| - Up to two DNS and WINS servers to be sent via IKEv1 ModeConfig can be | |
| configured in the pluto section of strongswan.conf. | |
| strongswan-4.2.14 | |
| ----------------- | |
| - The new server-side EAP RADIUS plugin (--enable-eap-radius) | |
| relays EAP messages to and from a RADIUS server. Successfully | |
| tested with with a freeradius server using EAP-MD5 and EAP-SIM. | |
| - A vulnerability in the Dead Peer Detection (RFC 3706) code was found by | |
| Gerd v. Egidy <gerd.von.egidy@intra2net.com> of Intra2net AG affecting | |
| all Openswan and strongSwan releases. A malicious (or expired ISAKMP) | |
| R_U_THERE or R_U_THERE_ACK Dead Peer Detection packet can cause the | |
| pluto IKE daemon to crash and restart. No authentication or encryption | |
| is required to trigger this bug. One spoofed UDP packet can cause the | |
| pluto IKE daemon to restart and be unresponsive for a few seconds while | |
| restarting. This DPD null state vulnerability has been officially | |
| registered as CVE-2009-0790 and is fixed by this release. | |
| - ASN.1 to time_t conversion caused a time wrap-around for | |
| dates after Jan 18 03:14:07 UTC 2038 on 32-bit platforms. | |
| As a workaround such dates are set to the maximum representable | |
| time, i.e. Jan 19 03:14:07 UTC 2038. | |
| - Distinguished Names containing wildcards (*) are not sent in the | |
| IDr payload anymore. | |
| strongswan-4.2.13 | |
| ----------------- | |
| - Fixed a use-after-free bug in the DPD timeout section of the | |
| IKEv1 pluto daemon which sporadically caused a segfault. | |
| - Fixed a crash in the IKEv2 charon daemon occurring with | |
| mixed RAM-based and SQL-based virtual IP address pools. | |
| - Fixed ASN.1 parsing of algorithmIdentifier objects where the | |
| parameters field is optional. | |
| - Ported nm plugin to NetworkManager 7.1. | |
| strongswan-4.2.12 | |
| ----------------- | |
| - Support of the EAP-MSCHAPv2 protocol enabled by the option | |
| --enable-eap-mschapv2. Requires the MD4 hash algorithm enabled | |
| either by --enable-md4 or --enable-openssl. | |
| - Assignment of up to two DNS and up to two WINS servers to peers via | |
| the IKEv2 Configuration Payload (CP). The IPv4 or IPv6 nameserver | |
| addresses are defined in strongswan.conf. | |
| - The strongSwan applet for the Gnome NetworkManager is now built and | |
| distributed as a separate tarball under the name NetworkManager-strongswan. | |
| strongswan-4.2.11 | |
| ----------------- | |
| - Fixed ESP NULL encryption broken by the refactoring of keymat.c. | |
| Also introduced proper initialization and disposal of keying material. | |
| - Fixed the missing listing of connection definitions in ipsec statusall | |
| broken by an unfortunate local variable overload. | |
| strongswan-4.2.10 | |
| ----------------- | |
| - Several performance improvements to handle thousands of tunnels with almost | |
| linear upscaling. All relevant data structures have been replaced by faster | |
| counterparts with better lookup times. | |
| - Better parallelization to run charon on multiple cores. Due to improved | |
| ressource locking and other optimizations the daemon can take full | |
| advantage of 16 or even more cores. | |
| - The load-tester plugin can use a NULL Diffie-Hellman group and simulate | |
| unique identities and certificates by signing peer certificates using a CA | |
| on the fly. | |
| - The redesigned stroke in-memory IP pool handles leases. The "ipsec leases" | |
| command queries assigned leases. | |
| - Added support for smartcards in charon by using the ENGINE API provided by | |
| OpenSSL, based on patches by Michael Roßberg. | |
| - The Padlock plugin supports the hardware RNG found on VIA CPUs to provide a | |
| reliable source of randomness. | |
| strongswan-4.2.9 | |
| ---------------- | |
| - Flexible configuration of logging subsystem allowing to log to multiple | |
| syslog facilities or to files using fine-grained log levels for each target. | |
| - Load testing plugin to do stress testing of the IKEv2 daemon against self | |
| or another host. Found and fixed issues during tests in the multi-threaded | |
| use of the OpenSSL plugin. | |
| - Added profiling code to synchronization primitives to find bottlenecks if | |
| running on multiple cores. Found and fixed an issue where parts of the | |
| Diffie-Hellman calculation acquired an exclusive lock. This greatly improves | |
| parallelization to multiple cores. | |
| - updown script invocation has been separated into a plugin of its own to | |
| further slim down the daemon core. | |
| - Separated IKE_SA/CHILD_SA key derivation process into a closed system, | |
| allowing future implementations to use a secured environment in e.g. kernel | |
| memory or hardware. | |
| - The kernel interface of charon has been modularized. XFRM NETLINK (default) | |
| and PFKEY (--enable-kernel-pfkey) interface plugins for the native IPsec | |
| stack of the Linux 2.6 kernel as well as a PFKEY interface for the KLIPS | |
| IPsec stack (--enable-kernel-klips) are provided. | |
| - Basic Mobile IPv6 support has been introduced, securing Binding Update | |
| messages as well as tunneled traffic between Mobile Node and Home Agent. | |
| The installpolicy=no option allows peaceful cooperation with a dominant | |
| mip6d daemon and the new type=transport_proxy implements the special MIPv6 | |
| IPsec transport proxy mode where the IKEv2 daemon uses the Care-of-Address | |
| but the IPsec SA is set up for the Home Address. | |
| - Implemented migration of Mobile IPv6 connections using the KMADDRESS | |
| field contained in XFRM_MSG_MIGRATE messages sent by the mip6d daemon | |
| via the Linux 2.6.28 (or appropriately patched) kernel. | |
| strongswan-4.2.8 | |
| ---------------- | |
| - IKEv2 charon daemon supports authentication based on raw public keys | |
| stored in the SQL database backend. The ipsec listpubkeys command | |
| lists the available raw public keys via the stroke interface. | |
| - Several MOBIKE improvements: Detect changes in NAT mappings in DPD exchanges, | |
| handle events if kernel detects NAT mapping changes in UDP-encapsulated | |
| ESP packets (requires kernel patch), reuse old addesses in MOBIKE updates as | |
| long as possible and other fixes. | |
| - Fixed a bug in addr_in_subnet() which caused insertion of wrong source | |
| routes for destination subnets having netwmasks not being a multiple of 8 bits. | |
| Thanks go to Wolfgang Steudel, TU Ilmenau for reporting this bug. | |
| strongswan-4.2.7 | |
| ---------------- | |
| - Fixed a Denial-of-Service vulnerability where an IKE_SA_INIT message with | |
| a KE payload containing zeroes only can cause a crash of the IKEv2 charon | |
| daemon due to a NULL pointer returned by the mpz_export() function of the | |
| GNU Multiprecision Library (GMP). Thanks go to Mu Dynamics Research Labs | |
| for making us aware of this problem. | |
| - The new agent plugin provides a private key implementation on top of an | |
| ssh-agent. | |
| - The NetworkManager plugin has been extended to support certificate client | |
| authentication using RSA keys loaded from a file or using ssh-agent. | |
| - Daemon capability dropping has been ported to libcap and must be enabled | |
| explicitly --with-capabilities=libcap. Future version will support the | |
| newer libcap2 library. | |
| - ipsec listalgs lists the IKEv2 cryptografic algorithms registered with the | |
| charon keying daemon. | |
| strongswan-4.2.6 | |
| ---------------- | |
| - A NetworkManager plugin allows GUI-based configuration of road-warrior | |
| clients in a simple way. It features X509 based gateway authentication | |
| and EAP client authentication, tunnel setup/teardown and storing passwords | |
| in the Gnome Keyring. | |
| - A new EAP-GTC plugin implements draft-sheffer-ikev2-gtc-00.txt and allows | |
| username/password authentication against any PAM service on the gateway. | |
| The new EAP method interacts nicely with the NetworkManager plugin and allows | |
| client authentication against e.g. LDAP. | |
| - Improved support for the EAP-Identity method. The new ipsec.conf eap_identity | |
| parameter defines an additional identity to pass to the server in EAP | |
| authentication. | |
| - The "ipsec statusall" command now lists CA restrictions, EAP | |
| authentication types and EAP identities. | |
| - Fixed two multithreading deadlocks occurring when starting up | |
| several hundred tunnels concurrently. | |
| - Fixed the --enable-integrity-test configure option which | |
| computes a SHA-1 checksum over the libstrongswan library. | |
| strongswan-4.2.5 | |
| ---------------- | |
| - Consistent logging of IKE and CHILD SAs at the audit (AUD) level. | |
| - Improved the performance of the SQL-based virtual IP address pool | |
| by introducing an additional addresses table. The leases table | |
| storing only history information has become optional and can be | |
| disabled by setting charon.plugins.sql.lease_history = no in | |
| strongswan.conf. | |
| - The XFRM_STATE_AF_UNSPEC flag added to xfrm.h allows IPv4-over-IPv6 | |
| and IPv6-over-IPv4 tunnels with the 2.6.26 and later Linux kernels. | |
| - management of different virtual IP pools for different | |
| network interfaces have become possible. | |
| - fixed a bug which prevented the assignment of more than 256 | |
| virtual IP addresses from a pool managed by an sql database. | |
| - fixed a bug which did not delete own IPCOMP SAs in the kernel. | |
| strongswan-4.2.4 | |
| ---------------- | |
| - Added statistics functions to ipsec pool --status and ipsec pool --leases | |
| and input validation checks to various ipsec pool commands. | |
| - ipsec statusall now lists all loaded charon plugins and displays | |
| the negotiated IKEv2 cipher suite proposals. | |
| - The openssl plugin supports the elliptic curve Diffie-Hellman groups | |
| 19, 20, 21, 25, and 26. | |
| - The openssl plugin supports ECDSA authentication using elliptic curve | |
| X.509 certificates. | |
| - Fixed a bug in stroke which caused multiple charon threads to close | |
| the file descriptors during packet transfers over the stroke socket. | |
| - ESP sequence numbers are now migrated in IPsec SA updates handled by | |
| MOBIKE. Works only with Linux kernels >= 2.6.17. | |
| strongswan-4.2.3 | |
| ---------------- | |
| - Fixed the strongswan.conf path configuration problem that occurred when | |
| --sysconfig was not set explicitly in ./configure. | |
| - Fixed a number of minor bugs that where discovered during the 4th | |
| IKEv2 interoperability workshop in San Antonio, TX. | |
| strongswan-4.2.2 | |
| ---------------- | |
| - Plugins for libstrongswan and charon can optionally be loaded according | |
| to a configuration in strongswan.conf. Most components provide a | |
| "load = " option followed by a space separated list of plugins to load. | |
| This allows e.g. the fallback from a hardware crypto accelerator to | |
| to software-based crypto plugins. | |
| - Charons SQL plugin has been extended by a virtual IP address pool. | |
| Configurations with a rightsourceip=%poolname setting query a SQLite or | |
| MySQL database for leases. The "ipsec pool" command helps in administrating | |
| the pool database. See ipsec pool --help for the available options | |
| - The Authenticated Encryption Algorithms AES-CCM-8/12/16 and AES-GCM-8/12/16 | |
| for ESP are now supported starting with the Linux 2.6.25 kernel. The | |
| syntax is e.g. esp=aes128ccm12 or esp=aes256gcm16. | |
| strongswan-4.2.1 | |
| ---------------- | |
| - Support for "Hash and URL" encoded certificate payloads has been implemented | |
| in the IKEv2 daemon charon. Using the "certuribase" option of a CA section | |
| allows to assign a base URL to all certificates issued by the specified CA. | |
| The final URL is then built by concatenating that base and the hex encoded | |
| SHA1 hash of the DER encoded certificate. Note that this feature is disabled | |
| by default and must be enabled using the option "charon.hash_and_url". | |
| - The IKEv2 daemon charon now supports the "uniqueids" option to close multiple | |
| IKE_SAs with the same peer. The option value "keep" prefers existing | |
| connection setups over new ones, where the value "replace" replaces existing | |
| connections. | |
| - The crypto factory in libstrongswan additionally supports random number | |
| generators, plugins may provide other sources of randomness. The default | |
| plugin reads raw random data from /dev/(u)random. | |
| - Extended the credential framework by a caching option to allow plugins | |
| persistent caching of fetched credentials. The "cachecrl" option has been | |
| re-implemented. | |
| - The new trustchain verification introduced in 4.2.0 has been parallelized. | |
| Threads fetching CRL or OCSP information no longer block other threads. | |
| - A new IKEv2 configuration attribute framework has been introduced allowing | |
| plugins to provide virtual IP addresses, and in the future, other | |
| configuration attribute services (e.g. DNS/WINS servers). | |
| - The stroke plugin has been extended to provide virtual IP addresses from | |
| a pool defined in ipsec.conf. The "rightsourceip" parameter now accepts | |
| address pools in CIDR notation (e.g. 10.1.1.0/24). The parameter also accepts | |
| the value "%poolname", where "poolname" identifies a pool provided by a | |
| separate plugin. | |
| - Fixed compilation on uClibc and a couple of other minor bugs. | |
| - Set DPD defaults in ipsec starter to dpd_delay=30s and dpd_timeout=150s. | |
| - The IKEv1 pluto daemon now supports the ESP encryption algorithm CAMELLIA | |
| with key lengths of 128, 192, and 256 bits, as well as the authentication | |
| algorithm AES_XCBC_MAC. Configuration example: esp=camellia192-aesxcbc. | |
| strongswan-4.2.0 | |
| ---------------- | |
| - libstrongswan has been modularized to attach crypto algorithms, | |
| credential implementations (keys, certificates) and fetchers dynamically | |
| through plugins. Existing code has been ported to plugins: | |
| - RSA/Diffie-Hellman implementation using the GNU Multi Precision library | |
| - X509 certificate system supporting CRLs, OCSP and attribute certificates | |
| - Multiple plugins providing crypto algorithms in software | |
| - CURL and OpenLDAP fetcher | |
| - libstrongswan gained a relational database API which uses pluggable database | |
| providers. Plugins for MySQL and SQLite are available. | |
| - The IKEv2 keying daemon charon is more extensible. Generic plugins may provide | |
| connection configuration, credentials and EAP methods or control the daemon. | |
| Existing code has been ported to plugins: | |
| - EAP-AKA, EAP-SIM, EAP-MD5 and EAP-Identity | |
| - stroke configuration, credential and control (compatible to pluto) | |
| - XML bases management protocol to control and query the daemon | |
| The following new plugins are available: | |
| - An experimental SQL configuration, credential and logging plugin on | |
| top of either MySQL or SQLite | |
| - A unit testing plugin to run tests at daemon startup | |
| - The authentication and credential framework in charon has been heavily | |
| refactored to support modular credential providers, proper | |
| CERTREQ/CERT payload exchanges and extensible authorization rules. | |
| - The framework of strongSwan Manager has envolved to the web application | |
| framework libfast (FastCGI Application Server w/ Templates) and is usable | |
| by other applications. | |
| strongswan-4.1.11 | |
| ----------------- | |
| - IKE rekeying in NAT situations did not inherit the NAT conditions | |
| to the rekeyed IKE_SA so that the UDP encapsulation was lost with | |
| the next CHILD_SA rekeying. | |
| - Wrong type definition of the next_payload variable in id_payload.c | |
| caused an INVALID_SYNTAX error on PowerPC platforms. | |
| - Implemented IKEv2 EAP-SIM server and client test modules that use | |
| triplets stored in a file. For details on the configuration see | |
| the scenario 'ikev2/rw-eap-sim-rsa'. | |
| strongswan-4.1.10 | |
| ----------------- | |
| - Fixed error in the ordering of the certinfo_t records in the ocsp cache that | |
| caused multiple entries of the same serial number to be created. | |
| - Implementation of a simple EAP-MD5 module which provides CHAP | |
| authentication. This may be interesting in conjunction with certificate | |
| based server authentication, as weak passwords can't be brute forced | |
| (in contradiction to traditional IKEv2 PSK). | |
| - A complete software based implementation of EAP-AKA, using algorithms | |
| specified in 3GPP2 (S.S0055). This implementation does not use an USIM, | |
| but reads the secrets from ipsec.secrets. Make sure to read eap_aka.h | |
| before using it. | |
| - Support for vendor specific EAP methods using Expanded EAP types. The | |
| interface to EAP modules has been slightly changed, so make sure to | |
| check the changes if you're already rolling your own modules. | |
| strongswan-4.1.9 | |
| ---------------- | |
| - The default _updown script now dynamically inserts and removes ip6tables | |
| firewall rules if leftfirewall=yes is set in IPv6 connections. New IPv6 | |
| net-net and roadwarrior (PSK/RSA) scenarios for both IKEv1 and IKEV2 were | |
| added. | |
| - Implemented RFC4478 repeated authentication to force EAP/Virtual-IP clients | |
| to reestablish an IKE_SA within a given timeframe. | |
| - strongSwan Manager supports configuration listing, initiation and termination | |
| of IKE and CHILD_SAs. | |
| - Fixes and improvements to multithreading code. | |
| - IKEv2 plugins have been renamed to libcharon-* to avoid naming conflicts. | |
| Make sure to remove the old plugins in $libexecdir/ipsec, otherwise they get | |
| loaded twice. | |
| strongswan-4.1.8 | |
| ---------------- | |
| - Removed recursive pthread mutexes since uClibc doesn't support them. | |
| strongswan-4.1.7 | |
| ---------------- | |
| - In NAT traversal situations and multiple queued Quick Modes, | |
| those pending connections inserted by auto=start after the | |
| port floating from 500 to 4500 were erronously deleted. | |
| - Added a "forceencaps" connection parameter to enforce UDP encapsulation | |
| to surmount restrictive firewalls. NAT detection payloads are faked to | |
| simulate a NAT situation and trick the other peer into NAT mode (IKEv2 only). | |
| - Preview of strongSwan Manager, a web based configuration and monitoring | |
| application. It uses a new XML control interface to query the IKEv2 daemon | |
| (see http://wiki.strongswan.org/wiki/Manager). | |
| - Experimental SQLite configuration backend which will provide the configuration | |
| interface for strongSwan Manager in future releases. | |
| - Further improvements to MOBIKE support. | |
| strongswan-4.1.6 | |
| ---------------- | |
| - Since some third party IKEv2 implementations run into | |
| problems with strongSwan announcing MOBIKE capability per | |
| default, MOBIKE can be disabled on a per-connection-basis | |
| using the mobike=no option. Whereas mobike=no disables the | |
| sending of the MOBIKE_SUPPORTED notification and the floating | |
| to UDP port 4500 with the IKE_AUTH request even if no NAT | |
| situation has been detected, strongSwan will still support | |
| MOBIKE acting as a responder. | |
| - the default ipsec routing table plus its corresponding priority | |
| used for inserting source routes has been changed from 100 to 220. | |
| It can be configured using the --with-ipsec-routing-table and | |
| --with-ipsec-routing-table-prio options. | |
| - the --enable-integrity-test configure option tests the | |
| integrity of the libstrongswan crypto code during the charon | |
| startup. | |
| - the --disable-xauth-vid configure option disables the sending | |
| of the XAUTH vendor ID. This can be used as a workaround when | |
| interoperating with some Windows VPN clients that get into | |
| trouble upon reception of an XAUTH VID without eXtended | |
| AUTHentication having been configured. | |
| - ipsec stroke now supports the rereadsecrets, rereadaacerts, | |
| rereadacerts, and listacerts options. | |
| strongswan-4.1.5 | |
| ---------------- | |
| - If a DNS lookup failure occurs when resolving right=%<FQDN> | |
| or right=<FQDN> combined with rightallowany=yes then the | |
| connection is not updated by ipsec starter thus preventing | |
| the disruption of an active IPsec connection. Only if the DNS | |
| lookup successfully returns with a changed IP address the | |
| corresponding connection definition is updated. | |
| - Routes installed by the keying daemons are now in a separate | |
| routing table with the ID 100 to avoid conflicts with the main | |
| table. Route lookup for IKEv2 traffic is done in userspace to ignore | |
| routes installed for IPsec, as IKE traffic shouldn't get encapsulated. | |
| strongswan-4.1.4 | |
| ---------------- | |
| - The pluto IKEv1 daemon now exhibits the same behaviour as its | |
| IKEv2 companion charon by inserting an explicit route via the | |
| _updown script only if a sourceip exists. This is admissible | |
| since routing through the IPsec tunnel is handled automatically | |
| by NETKEY's IPsec policies. As a consequence the left|rightnexthop | |
| parameter is not required any more. | |
| - The new IKEv1 parameter right|leftallowany parameters helps to handle | |
| the case where both peers possess dynamic IP addresses that are | |
| usually resolved using DynDNS or a similar service. The configuration | |
| right=peer.foo.bar | |
| rightallowany=yes | |
| can be used by the initiator to start up a connection to a peer | |
| by resolving peer.foo.bar into the currently allocated IP address. | |
| Thanks to the rightallowany flag the connection behaves later on | |
| as | |
| right=%any | |
| so that the peer can rekey the connection as an initiator when his | |
| IP address changes. An alternative notation is | |
| right=%peer.foo.bar | |
| which will implicitly set rightallowany=yes. | |
| - ipsec starter now fails more gracefully in the presence of parsing | |
| errors. Flawed ca and conn section are discarded and pluto is started | |
| if non-fatal errors only were encountered. If right=%peer.foo.bar | |
| cannot be resolved by DNS then right=%any will be used so that passive | |
| connections as a responder are still possible. | |
| - The new pkcs11initargs parameter that can be placed in the | |
| setup config section of /etc/ipsec.conf allows the definition | |
| of an argument string that is used with the PKCS#11 C_Initialize() | |
| function. This non-standard feature is required by the NSS softoken | |
| library. This patch was contributed by Robert Varga. | |
| - Fixed a bug in ipsec starter introduced by strongswan-2.8.5 | |
| which caused a segmentation fault in the presence of unknown | |
| or misspelt keywords in ipsec.conf. This bug fix was contributed | |
| by Robert Varga. | |
| - Partial support for MOBIKE in IKEv2. The initiator acts on interface/ | |
| address configuration changes and updates IKE and IPsec SAs dynamically. | |
| strongswan-4.1.3 | |
| ---------------- | |
| - IKEv2 peer configuration selection now can be based on a given | |
| certification authority using the rightca= statement. | |
| - IKEv2 authentication based on RSA signatures now can handle multiple | |
| certificates issued for a given peer ID. This allows a smooth transition | |
| in the case of a peer certificate renewal. | |
| - IKEv2: Support for requesting a specific virtual IP using leftsourceip on the | |
| client and returning requested virtual IPs using rightsourceip=%config | |
| on the server. If the server does not support configuration payloads, the | |
| client enforces its leftsourceip parameter. | |
| - The ./configure options --with-uid/--with-gid allow pluto and charon | |
| to drop their privileges to a minimum and change to an other UID/GID. This | |
| improves the systems security, as a possible intruder may only get the | |
| CAP_NET_ADMIN capability. | |
| - Further modularization of charon: Pluggable control interface and | |
| configuration backend modules provide extensibility. The control interface | |
| for stroke is included, and further interfaces using DBUS (NetworkManager) | |
| or XML are on the way. A backend for storing configurations in the daemon | |
| is provided and more advanced backends (using e.g. a database) are trivial | |
| to implement. | |
| - Fixed a compilation failure in libfreeswan occurring with Linux kernel | |
| headers > 2.6.17. | |
| strongswan-4.1.2 | |
| ---------------- | |
| - Support for an additional Diffie-Hellman exchange when creating/rekeying | |
| a CHILD_SA in IKEv2 (PFS). PFS is enabled when the proposal contains a | |
| DH group (e.g. "esp=aes128-sha1-modp1536"). Further, DH group negotiation | |
| is implemented properly for rekeying. | |
| - Support for the AES-XCBC-96 MAC algorithm for IPsec SAs when using IKEv2 | |
| (requires linux >= 2.6.20). It is enabled using e.g. "esp=aes256-aesxcbc". | |
| - Working IPv4-in-IPv6 and IPv6-in-IPv4 tunnels for linux >= 2.6.21. | |
| - Added support for EAP modules which do not establish an MSK. | |
| - Removed the dependencies from the /usr/include/linux/ headers by | |
| including xfrm.h, ipsec.h, and pfkeyv2.h in the distribution. | |
| - crlNumber is now listed by ipsec listcrls | |
| - The xauth_modules.verify_secret() function now passes the | |
| connection name. | |
| strongswan-4.1.1 | |
| ---------------- | |
| - Server side cookie support. If to may IKE_SAs are in CONNECTING state, | |
| cookies are enabled and protect against DoS attacks with faked source | |
| addresses. Number of IKE_SAs in CONNECTING state is also limited per | |
| peer address to avoid resource exhaustion. IKE_SA_INIT messages are | |
| compared to properly detect retransmissions and incoming retransmits are | |
| detected even if the IKE_SA is blocked (e.g. doing OCSP fetches). | |
| - The IKEv2 daemon charon now supports dynamic http- and ldap-based CRL | |
| fetching enabled by crlcheckinterval > 0 and caching fetched CRLs | |
| enabled by cachecrls=yes. | |
| - Added the configuration options --enable-nat-transport which enables | |
| the potentially insecure NAT traversal for IPsec transport mode and | |
| --disable-vendor-id which disables the sending of the strongSwan | |
| vendor ID. | |
| - Fixed a long-standing bug in the pluto IKEv1 daemon which caused | |
| a segmentation fault if a malformed payload was detected in the | |
| IKE MR2 message and pluto tried to send an encrypted notification | |
| message. | |
| - Added the NATT_IETF_02_N Vendor ID in order to support IKEv1 connections | |
| with Windows 2003 Server which uses a wrong VID hash. | |
| strongswan-4.1.0 | |
| ---------------- | |
| - Support of SHA2_384 hash function for protecting IKEv1 | |
| negotiations and support of SHA2 signatures in X.509 certificates. | |
| - Fixed a serious bug in the computation of the SHA2-512 HMAC | |
| function. Introduced automatic self-test of all IKEv1 hash | |
| and hmac functions during pluto startup. Failure of a self-test | |
| currently issues a warning only but does not exit pluto [yet]. | |
| - Support for SHA2-256/384/512 PRF and HMAC functions in IKEv2. | |
| - Full support of CA information sections. ipsec listcainfos | |
| now shows all collected crlDistributionPoints and OCSP | |
| accessLocations. | |
| - Support of the Online Certificate Status Protocol (OCSP) for IKEv2. | |
| This feature requires the HTTP fetching capabilities of the libcurl | |
| library which must be enabled by setting the --enable-http configure | |
| option. | |
| - Refactored core of the IKEv2 message processing code, allowing better | |
| code reuse and separation. | |
| - Virtual IP support in IKEv2 using INTERNAL_IP4/6_ADDRESS configuration | |
| payload. Additionally, the INTERNAL_IP4/6_DNS attribute is interpreted | |
| by the requestor and installed in a resolv.conf file. | |
| - The IKEv2 daemon charon installs a route for each IPsec policy to use | |
| the correct source address even if an application does not explicitly | |
| specify it. | |
| - Integrated the EAP framework into charon which loads pluggable EAP library | |
| modules. The ipsec.conf parameter authby=eap initiates EAP authentication | |
| on the client side, while the "eap" parameter on the server side defines | |
| the EAP method to use for client authentication. | |
| A generic client side EAP-Identity module and an EAP-SIM authentication | |
| module using a third party card reader implementation are included. | |
| - Added client side support for cookies. | |
| - Integrated the fixes done at the IKEv2 interoperability bakeoff, including | |
| strict payload order, correct INVALID_KE_PAYLOAD rejection and other minor | |
| fixes to enhance interoperability with other implementations. | |
| strongswan-4.0.7 | |
| ---------------- | |
| - strongSwan now interoperates with the NCP Secure Entry Client, | |
| the Shrew Soft VPN Client, and the Cisco VPN client, doing both | |
| XAUTH and Mode Config. | |
| - UNITY attributes are now recognized and UNITY_BANNER is set | |
| to a default string. | |
| strongswan-4.0.6 | |
| ---------------- | |
| - IKEv1: Support for extended authentication (XAUTH) in combination | |
| with ISAKMP Main Mode RSA or PSK authentication. Both client and | |
| server side were implemented. Handling of user credentials can | |
| be done by a run-time loadable XAUTH module. By default user | |
| credentials are stored in ipsec.secrets. | |
| - IKEv2: Support for reauthentication when rekeying | |
| - IKEv2: Support for transport mode | |
| - fixed a lot of bugs related to byte order | |
| - various other bugfixes | |
| strongswan-4.0.5 | |
| ---------------- | |
| - IKEv1: Implementation of ModeConfig push mode via the new connection | |
| keyword modeconfig=push allows interoperability with Cisco VPN gateways. | |
| - IKEv1: The command ipsec statusall now shows "DPD active" for all | |
| ISAKMP SAs that are under active Dead Peer Detection control. | |
| - IKEv2: Charon's logging and debugging framework has been completely rewritten. | |
| Instead of logger, special printf() functions are used to directly | |
| print objects like hosts (%H) identifications (%D), certificates (%Q), | |
| etc. The number of debugging levels have been reduced to: | |
| 0 (audit), 1 (control), 2 (controlmore), 3 (raw), 4 (private) | |
| The debugging levels can either be specified statically in ipsec.conf as | |
| config setup | |
| charondebug="lib 1, cfg 3, net 2" | |
| or changed at runtime via stroke as | |
| ipsec stroke loglevel cfg 2 | |
| strongswan-4.0.4 | |
| ---------------- | |
| - Implemented full support for IPv6-in-IPv6 tunnels. | |
| - Added configuration options for dead peer detection in IKEv2. dpd_action | |
| types "clear", "hold" and "restart" are supported. The dpd_timeout | |
| value is not used, as the normal retransmission policy applies to | |
| detect dead peers. The dpd_delay parameter enables sending of empty | |
| informational message to detect dead peers in case of inactivity. | |
| - Added support for preshared keys in IKEv2. PSK keys configured in | |
| ipsec.secrets are loaded. The authby parameter specifies the authentication | |
| method to authentificate ourself, the other peer may use PSK or RSA. | |
| - Changed retransmission policy to respect the keyingtries parameter. | |
| - Added private key decryption. PEM keys encrypted with AES-128/192/256 | |
| or 3DES are supported. | |
| - Implemented DES/3DES algorithms in libstrongswan. 3DES can be used to | |
| encrypt IKE traffic. | |
| - Implemented SHA-256/384/512 in libstrongswan, allows usage of certificates | |
| signed with such a hash algorithm. | |
| - Added initial support for updown scripts. The actions up-host/client and | |
| down-host/client are executed. The leftfirewall=yes parameter | |
| uses the default updown script to insert dynamic firewall rules, a custom | |
| updown script may be specified with the leftupdown parameter. | |
| strongswan-4.0.3 | |
| ---------------- | |
| - Added support for the auto=route ipsec.conf parameter and the | |
| ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and | |
| CHILD_SAs dynamically on demand when traffic is detected by the | |
| kernel. | |
| - Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter. | |
| As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only | |
| new keys are generated using perfect forward secrecy. An optional flag | |
| which enforces reauthentication will be implemented later. | |
| - "sha" and "sha1" are now treated as synonyms in the ike= and esp= | |
| algorithm configuration statements. | |
| strongswan-4.0.2 | |
| ---------------- | |
| - Full X.509 certificate trust chain verification has been implemented. | |
| End entity certificates can be exchanged via CERT payloads. The current | |
| default is leftsendcert=always, since CERTREQ payloads are not supported | |
| yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls. | |
| - Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2 | |
| would offer more possibilities for traffic selection, but the Linux kernel | |
| currently does not support it. That's why we stick with these simple | |
| ipsec.conf rules for now. | |
| - Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no | |
| IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear, | |
| dpddelay=60s). | |
| - Initial NAT traversal support in IKEv2. Charon includes NAT detection | |
| notify payloads to detect NAT routers between the peers. It switches | |
| to port 4500, uses UDP encapsulated ESP packets, handles peer address | |
| changes gracefully and sends keep alive message periodically. | |
| - Reimplemented IKE_SA state machine for charon, which allows simultaneous | |
| rekeying, more shared code, cleaner design, proper retransmission | |
| and a more extensible code base. | |
| - The mixed PSK/RSA roadwarrior detection capability introduced by the | |
| strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal | |
| payloads by the responder right before any defined IKE Main Mode state had | |
| been established. Although any form of bad proposal syntax was being correctly | |
| detected by the payload parser, the subsequent error handler didn't check | |
| the state pointer before logging current state information, causing an | |
| immediate crash of the pluto keying daemon due to a NULL pointer. | |
| strongswan-4.0.1 | |
| ---------------- | |
| - Added algorithm selection to charon: New default algorithms for | |
| ike=aes128-sha-modp2048, as both daemons support it. The default | |
| for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles | |
| the ike/esp parameter the same way as pluto. As this syntax does | |
| not allow specification of a pseudo random function, the same | |
| algorithm as for integrity is used (currently sha/md5). Supported | |
| algorithms for IKE: | |
| Encryption: aes128, aes192, aes256 | |
| Integrity/PRF: md5, sha (using hmac) | |
| DH-Groups: modp768, 1024, 1536, 2048, 4096, 8192 | |
| and for ESP: | |
| Encryption: aes128, aes192, aes256, 3des, blowfish128, | |
| blowfish192, blowfish256 | |
| Integrity: md5, sha1 | |
| More IKE encryption algorithms will come after porting libcrypto into | |
| libstrongswan. | |
| - initial support for rekeying CHILD_SAs using IKEv2. Currently no | |
| perfect forward secrecy is used. The rekeying parameters rekey, | |
| rekeymargin, rekeyfuzz and keylife from ipsec.conf are now supported | |
| when using IKEv2. WARNING: charon currently is unable to handle | |
| simultaneous rekeying. To avoid such a situation, use a large | |
| rekeyfuzz, or even better, set rekey=no on one peer. | |
| - support for host2host, net2net, host2net (roadwarrior) tunnels | |
| using predefined RSA certificates (see uml scenarios for | |
| configuration examples). | |
| - new build environment featuring autotools. Features such | |
| as HTTP, LDAP and smartcard support may be enabled using | |
| the ./configure script. Changing install directories | |
| is possible, too. See ./configure --help for more details. | |
| - better integration of charon with ipsec starter, which allows | |
| (almost) transparent operation with both daemons. charon | |
| handles ipsec commands up, down, status, statusall, listall, | |
| listcerts and allows proper load, reload and delete of connections | |
| via ipsec starter. | |
| strongswan-4.0.0 | |
| ---------------- | |
| - initial support of the IKEv2 protocol. Connections in | |
| ipsec.conf designated by keyexchange=ikev2 are negotiated | |
| by the new IKEv2 charon keying daemon whereas those marked | |
| by keyexchange=ikev1 or the default keyexchange=ike are | |
| handled thy the IKEv1 pluto keying daemon. Currently only | |
| a limited subset of functions are available with IKEv2 | |
| (Default AES encryption, authentication based on locally | |
| imported X.509 certificates, unencrypted private RSA keys | |
| in PKCS#1 file format, limited functionality of the ipsec | |
| status command). | |
| strongswan-2.7.0 | |
| ---------------- | |
| - the dynamic iptables rules from the _updown_x509 template | |
| for KLIPS and the _updown_policy template for NETKEY have | |
| been merged into the default _updown script. The existing | |
| left|rightfirewall keyword causes the automatic insertion | |
| and deletion of ACCEPT rules for tunneled traffic upon | |
| the successful setup and teardown of an IPsec SA, respectively. | |
| left|rightfirwall can be used with KLIPS under any Linux 2.4 | |
| kernel or with NETKEY under a Linux kernel version >= 2.6.16 | |
| in conjunction with iptables >= 1.3.5. For NETKEY under a Linux | |
| kernel version < 2.6.16 which does not support IPsec policy | |
| matching yet, please continue to use a copy of the _updown_espmark | |
| template loaded via the left|rightupdown keyword. | |
| - a new left|righthostaccess keyword has been introduced which | |
| can be used in conjunction with left|rightfirewall and the | |
| default _updown script. By default leftfirewall=yes inserts | |
| a bi-directional iptables FORWARD rule for a local client network | |
| with a netmask different from 255.255.255.255 (single host). | |
| This does not allow to access the VPN gateway host via its | |
| internal network interface which is part of the client subnet | |
| because an iptables INPUT and OUTPUT rule would be required. | |
| lefthostaccess=yes will cause this additional ACCEPT rules to | |
| be inserted. | |
| - mixed PSK|RSA roadwarriors are now supported. The ISAKMP proposal | |
| payload is preparsed in order to find out whether the roadwarrior | |
| requests PSK or RSA so that a matching connection candidate can | |
| be found. | |
| strongswan-2.6.4 | |
| ---------------- | |
| - the new _updown_policy template allows ipsec policy based | |
| iptables firewall rules. Required are iptables version | |
| >= 1.3.5 and linux kernel >= 2.6.16. This script obsoletes | |
| the _updown_espmark template, so that no INPUT mangle rules | |
| are required any more. | |
| - added support of DPD restart mode | |
| - ipsec starter now allows the use of wildcards in include | |
| statements as e.g. in "include /etc/my_ipsec/*.conf". | |
| Patch courtesy of Matthias Haas. | |
| - the Netscape OID 'employeeNumber' is now recognized and can be | |
| used as a Relative Distinguished Name in certificates. | |
| strongswan-2.6.3 | |
| ---------------- | |
| - /etc/init.d/ipsec or /etc/rc.d/ipsec is now a copy of the ipsec | |
| command and not of ipsec setup any more. | |
| - ipsec starter now supports AH authentication in conjunction with | |
| ESP encryption. AH authentication is configured in ipsec.conf | |
| via the auth=ah parameter. | |
| - The command ipsec scencrypt|scdecrypt <args> is now an alias for | |
| ipsec whack --scencrypt|scdecrypt <args>. | |
| - get_sa_info() now determines for the native netkey IPsec stack | |
| the exact time of the last use of an active eroute. This information | |
| is used by the Dead Peer Detection algorithm and is also displayed by | |
| the ipsec status command. | |
| strongswan-2.6.2 | |
| ---------------- | |
| - running under the native Linux 2.6 IPsec stack, the function | |
| get_sa_info() is called by ipsec auto --status to display the current | |
| number of transmitted bytes per IPsec SA. | |
| - get_sa_info() is also used by the Dead Peer Detection process to detect | |
| recent ESP activity. If ESP traffic was received from the peer within | |
| the last dpd_delay interval then no R_Y_THERE notification must be sent. | |
| - strongSwan now supports the Relative Distinguished Name "unstructuredName" | |
| in ID_DER_ASN1_DN identities. The following notations are possible: | |
| rightid="unstructuredName=John Doe" | |
| rightid="UN=John Doe" | |
| - fixed a long-standing bug which caused PSK-based roadwarrior connections | |
| to segfault in the function id.c:same_id() called by keys.c:get_secret() | |
| if an FQDN, USER_FQDN, or Key ID was defined, as in the following example. | |
| conn rw | |
| right=%any | |
| rightid=@foo.bar | |
| authby=secret | |
| - the ipsec command now supports most ipsec auto commands (e.g. ipsec listall). | |
| - ipsec starter didn't set host_addr and client.addr ports in whack msg. | |
| - in order to guarantee backwards-compatibility with the script-based | |
| auto function (e.g. auto --replace), the ipsec starter scripts stores | |
| the defaultroute information in the temporary file /var/run/ipsec.info. | |
| - The compile-time option USE_XAUTH_VID enables the sending of the XAUTH | |
| Vendor ID which is expected by Cisco PIX 7 boxes that act as IKE Mode Config | |
| servers. | |
| - the ipsec starter now also recognizes the parameters authby=never and | |
| type=passthrough|pass|drop|reject. | |
| strongswan-2.6.1 | |
| ---------------- | |
| - ipsec starter now supports the also parameter which allows | |
| a modular structure of the connection definitions. Thus | |
| "ipsec start" is now ready to replace "ipsec setup". | |
| strongswan-2.6.0 | |
| ---------------- | |
| - Mathieu Lafon's popular ipsec starter tool has been added to the | |
| strongSwan distribution. Many thanks go to Stephan Scholz from astaro | |
| for his integration work. ipsec starter is a C program which is going | |
| to replace the various shell and awk starter scripts (setup, _plutoload, | |
| _plutostart, _realsetup, _startklips, _confread, and auto). Since | |
| ipsec.conf is now parsed only once, the starting of multiple tunnels is | |
| accelerated tremedously. | |
| - Added support of %defaultroute to the ipsec starter. If the IP address | |
| changes, a HUP signal to the ipsec starter will automatically | |
| reload pluto's connections. | |
| - moved most compile time configurations from pluto/Makefile to | |
| Makefile.inc by defining the options USE_LIBCURL, USE_LDAP, | |
| USE_SMARTCARD, and USE_NAT_TRAVERSAL_TRANSPORT_MODE. | |
| - removed the ipsec verify and ipsec newhostkey commands | |
| - fixed some 64-bit issues in formatted print statements | |
| - The scepclient functionality implementing the Simple Certificate | |
| Enrollment Protocol (SCEP) is nearly complete but hasn't been | |
| documented yet. | |
| strongswan-2.5.7 | |
| ---------------- | |
| - CA certicates are now automatically loaded from a smartcard | |
| or USB crypto token and appear in the ipsec auto --listcacerts | |
| listing. | |
| strongswan-2.5.6 | |
| ---------------- | |
| - when using "ipsec whack --scencrypt <data>" with a PKCS#11 | |
| library that does not support the C_Encrypt() Cryptoki | |
| function (e.g. OpenSC), the RSA encryption is done in | |
| software using the public key fetched from the smartcard. | |
| - The scepclient function now allows to define the | |
| validity of a self-signed certificate using the --days, | |
| --startdate, and --enddate options. The default validity | |
| has been changed from one year to five years. | |
| strongswan-2.5.5 | |
| ---------------- | |
| - the config setup parameter pkcs11proxy=yes opens pluto's PKCS#11 | |
| interface to other applications for RSA encryption and decryption | |
| via the whack interface. Notation: | |
| ipsec whack --scencrypt <data> | |
| [--inbase 16|hex|64|base64|256|text|ascii] | |
| [--outbase 16|hex|64|base64|256|text|ascii] | |
| [--keyid <keyid>] | |
| ipsec whack --scdecrypt <data> | |
| [--inbase 16|hex|64|base64|256|text|ascii] | |
| [--outbase 16|hex|64|base64|256|text|ascii] | |
| [--keyid <keyid>] | |
| The default setting for inbase and outbase is hex. | |
| The new proxy interface can be used for securing symmetric | |
| encryption keys required by the cryptoloop or dm-crypt | |
| disk encryption schemes, especially in the case when | |
| pkcs11keepstate=yes causes pluto to lock the pkcs11 slot | |
| permanently. | |
| - if the file /etc/ipsec.secrets is lacking during the startup of | |
| pluto then the root-readable file /etc/ipsec.d/private/myKey.der | |
| containing a 2048 bit RSA private key and a matching self-signed | |
| certificate stored in the file /etc/ipsec.d/certs/selfCert.der | |
| is automatically generated by calling the function | |
| ipsec scepclient --out pkcs1 --out cert-self | |
| scepclient was written by Jan Hutter and Martin Willi, students | |
| at the University of Applied Sciences in Rapperswil, Switzerland. | |
| strongswan-2.5.4 | |
| ---------------- | |
| - the current extension of the PKCS#7 framework introduced | |
| a parsing error in PKCS#7 wrapped X.509 certificates that are | |
| e.g. transmitted by Windows XP when multi-level CAs are used. | |
| the parsing syntax has been fixed. | |
| - added a patch by Gerald Richter which tolerates multiple occurrences | |
| of the ipsec0 interface when using KLIPS. | |
| strongswan-2.5.3 | |
| ---------------- | |
| - with gawk-3.1.4 the word "default2 has become a protected | |
| keyword for use in switch statements and cannot be used any | |
| more in the strongSwan scripts. This problem has been | |
| solved by renaming "default" to "defaults" and "setdefault" | |
| in the scripts _confread and auto, respectively. | |
| - introduced the parameter leftsendcert with the values | |
| always|yes (the default, always send a cert) | |
| ifasked (send the cert only upon a cert request) | |
| never|no (never send a cert, used for raw RSA keys and | |
| self-signed certs) | |
| - fixed the initialization of the ESP key length to a default of | |
| 128 bits in the case that the peer does not send a key length | |
| attribute for AES encryption. | |
| - applied Herbert Xu's uniqueIDs patch | |
| - applied Herbert Xu's CLOEXEC patches | |
| strongswan-2.5.2 | |
| ---------------- | |
| - CRLs can now be cached also in the case when the issuer's | |
| certificate does not contain a subjectKeyIdentifier field. | |
| In that case the subjectKeyIdentifier is computed by pluto as the | |
| 160 bit SHA-1 hash of the issuer's public key in compliance | |
| with section 4.2.1.2 of RFC 3280. | |
| - Fixed a bug introduced by strongswan-2.5.1 which eliminated | |
| not only multiple Quick Modes of a given connection but also | |
| multiple connections between two security gateways. | |
| strongswan-2.5.1 | |
| ---------------- | |
| - Under the native IPsec of the Linux 2.6 kernel, a %trap eroute | |
| installed either by setting auto=route in ipsec.conf or by | |
| a connection put into hold, generates an XFRM_AQUIRE event | |
| for each packet that wants to use the not-yet exisiting | |
| tunnel. Up to now each XFRM_AQUIRE event led to an entry in | |
| the Quick Mode queue, causing multiple IPsec SA to be | |
| established in rapid succession. Starting with strongswan-2.5.1 | |
| only a single IPsec SA is established per host-pair connection. | |
| - Right after loading the PKCS#11 module, all smartcard slots are | |
| searched for certificates. The result can be viewed using | |
| the command | |
| ipsec auto --listcards | |
| The certificate objects found in the slots are numbered | |
| starting with #1, #2, etc. This position number can be used to address | |
| certificates (leftcert=%smartcard) and keys (: PIN %smartcard) | |
| in ipsec.conf and ipsec.secrets, respectively: | |
| %smartcard (selects object #1) | |
| %smartcard#1 (selects object #1) | |
| %smartcard#3 (selects object #3) | |
| As an alternative the existing retrieval scheme can be used: | |
| %smartcard:45 (selects object with id=45) | |
| %smartcard0 (selects first object in slot 0) | |
| %smartcard4:45 (selects object in slot 4 with id=45) | |
| - Depending on the settings of CKA_SIGN and CKA_DECRYPT | |
| private key flags either C_Sign() or C_Decrypt() is used | |
| to generate a signature. | |
| - The output buffer length parameter siglen in C_Sign() | |
| is now initialized to the actual size of the output | |
| buffer prior to the function call. This fixes the | |
| CKR_BUFFER_TOO_SMALL error that could occur when using | |
| the OpenSC PKCS#11 module. | |
| - Changed the initialization of the PKCS#11 CK_MECHANISM in | |
| C_SignInit() to mech = { CKM_RSA_PKCS, NULL_PTR, 0 }. | |
| - Refactored the RSA public/private key code and transferred it | |
| from keys.c to the new pkcs1.c file as a preparatory step | |
| towards the release of the SCEP client. | |
| strongswan-2.5.0 | |
| ---------------- | |
| - The loading of a PKCS#11 smartcard library module during | |
| runtime does not require OpenSC library functions any more | |
| because the corresponding code has been integrated into | |
| smartcard.c. Also the RSAREF pkcs11 header files have been | |
| included in a newly created pluto/rsaref directory so that | |
| no external include path has to be defined any longer. | |
| - A long-awaited feature has been implemented at last: | |
| The local caching of CRLs fetched via HTTP or LDAP, activated | |
| by the parameter cachecrls=yes in the config setup section | |
| of ipsec.conf. The dynamically fetched CRLs are stored under | |
| a unique file name containing the issuer's subjectKeyID | |
| in /etc/ipsec.d/crls. | |
| - Applied a one-line patch courtesy of Michael Richardson | |
| from the Openswan project which fixes the kernel-oops | |
| in KLIPS when an snmp daemon is running on the same box. | |
| strongswan-2.4.4 | |
| ---------------- | |
| - Eliminated null length CRL distribution point strings. | |
| - Fixed a trust path evaluation bug introduced with 2.4.3 | |
| strongswan-2.4.3 | |
| ---------------- | |
| - Improved the joint OCSP / CRL revocation policy. | |
| OCSP responses have precedence over CRL entries. | |
| - Introduced support of CRLv2 reason codes. | |
| - Fixed a bug with key-pad equipped readers which caused | |
| pluto to prompt for the pin via the console when the first | |
| occasion to enter the pin via the key-pad was missed. | |
| - When pluto is built with LDAP_V3 enabled, the library | |
| liblber required by newer versions of openldap is now | |
| included. | |
| strongswan-2.4.2 | |
| ---------------- | |
| - Added the _updown_espmark template which requires all | |
| incoming ESP traffic to be marked with a default mark | |
| value of 50. | |
| - Introduced the pkcs11keepstate parameter in the config setup | |
| section of ipsec.conf. With pkcs11keepstate=yes the PKCS#11 | |
| session and login states are kept as long as possible during | |
| the lifetime of pluto. This means that a PIN entry via a key | |
| pad has to be done only once. | |
| - Introduced the pkcs11module parameter in the config setup | |
| section of ipsec.conf which specifies the PKCS#11 module | |
| to be used with smart cards. Example: | |
| pkcs11module=/usr/lib/pkcs11/opensc-pkcs11.lo | |
| - Added support of smartcard readers equipped with a PIN pad. | |
| - Added patch by Jay Pfeifer which detects when netkey | |
| modules have been statically built into the Linux 2.6 kernel. | |
| - Added two patches by Herbert Xu. The first uses ip xfrm | |
| instead of setkey to flush the IPsec policy database. The | |
| second sets the optional flag in inbound IPComp SAs only. | |
| - Applied Ulrich Weber's patch which fixes an interoperability | |
| problem between native IPsec and KLIPS systems caused by | |
| setting the replay window to 32 instead of 0 for ipcomp. | |
| strongswan-2.4.1 | |
| ---------------- | |
| - Fixed a bug which caused an unwanted Mode Config request | |
| to be initiated in the case where "right" was used to denote | |
| the local side in ipsec.conf and "left" the remote side, | |
| contrary to the recommendation that "right" be remote and | |
| "left" be"local". | |
| strongswan-2.4.0a | |
| ----------------- | |
| - updated Vendor ID to strongSwan-2.4.0 | |
| - updated copyright statement to include David Buechi and | |
| Michael Meier | |
| strongswan-2.4.0 | |
| ---------------- | |
| - strongSwan now communicates with attached smartcards and | |
| USB crypto tokens via the standardized PKCS #11 interface. | |
| By default the OpenSC library from www.opensc.org is used | |
| but any other PKCS#11 library could be dynamically linked. | |
| strongSwan's PKCS#11 API was implemented by David Buechi | |
| and Michael Meier, both graduates of the Zurich University | |
| of Applied Sciences in Winterthur, Switzerland. | |
| - When a %trap eroute is triggered by an outgoing IP packet | |
| then the native IPsec stack of the Linux 2.6 kernel [often/ | |
| always?] returns an XFRM_ACQUIRE message with an undefined | |
| protocol family field and the connection setup fails. | |
| As a workaround IPv4 (AF_INET) is now assumed. | |
| - the results of the UML test scenarios are now enhanced | |
| with block diagrams of the virtual network topology used | |
| in a particular test. | |
| strongswan-2.3.2 | |
| ---------------- | |
| - fixed IV used to decrypt informational messages. | |
| This bug was introduced with Mode Config functionality. | |
| - fixed NCP Vendor ID. | |
| - undid one of Ulrich Weber's maximum udp size patches | |
| because it caused a segmentation fault with NAT-ed | |
| Delete SA messages. | |
| - added UML scenarios wildcards and attr-cert which | |
| demonstrate the implementation of IPsec policies based | |
| on wildcard parameters contained in Distinguished Names and | |
| on X.509 attribute certificates, respectively. | |
| strongswan-2.3.1 | |
| ---------------- | |
| - Added basic Mode Config functionality | |
| - Added Mathieu Lafon's patch which upgrades the status of | |
| the NAT-Traversal implementation to RFC 3947. | |
| - The _startklips script now also loads the xfrm4_tunnel | |
| module. | |
| - Added Ulrich Weber's netlink replay window size and | |
| maximum udp size patches. | |
| - UML testing now uses the Linux 2.6.10 UML kernel by default. | |
| strongswan-2.3.0 | |
| ---------------- | |
| - Eric Marchionni and Patrik Rayo, both recent graduates from | |
| the Zuercher Hochschule Winterthur in Switzerland, created a | |
| User-Mode-Linux test setup for strongSwan. For more details | |
| please read the INSTALL and README documents in the testing | |
| subdirectory. | |
| - Full support of group attributes based on X.509 attribute | |
| certificates. Attribute certificates can be generated | |
| using the openac facility. For more details see | |
| man ipsec_openac. | |
| The group attributes can be used in connection definitions | |
| in order to give IPsec access to specific user groups. | |
| This is done with the new parameter left|rightgroups as in | |
| rightgroups="Research, Sales" | |
| giving access to users possessing the group attributes | |
| Research or Sales, only. | |
| - In Quick Mode clients with subnet mask /32 are now | |
| coded as IP_V4_ADDRESS or IP_V6_ADDRESS. This should | |
| fix rekeying problems with the SafeNet/SoftRemote and NCP | |
| Secure Entry Clients. | |
| - Changed the defaults of the ikelifetime and keylife parameters | |
| to 3h and 1h, respectively. The maximum allowable values are | |
| now both set to 24 h. | |
| - Suppressed notification wars between two IPsec peers that | |
| could e.g. be triggered by incorrect ISAKMP encryption. | |
| - Public RSA keys can now have identical IDs if either the | |
| issuing CA or the serial number is different. The serial | |
| number of a certificate is now shown by the command | |
| ipsec auto --listpubkeys | |
| strongswan-2.2.2 | |
| ---------------- | |
| - Added Tuomo Soini's sourceip feature which allows a strongSwan | |
| roadwarrior to use a fixed Virtual IP (see README section 2.6) | |
| and reduces the well-known four tunnel case on VPN gateways to | |
| a single tunnel definition (see README section 2.4). | |
| - Fixed a bug occurring with NAT-Traversal enabled when the responder | |
| suddenly turns initiator and the initiator cannot find a matching | |
| connection because of the floated IKE port 4500. | |
| - Removed misleading ipsec verify command from barf. | |
| - Running under the native IP stack, ipsec --version now shows | |
| the Linux kernel version (courtesy to the Openswan project). | |
| strongswan-2.2.1 | |
| ---------------- | |
| - Introduced the ipsec auto --listalgs monitoring command which lists | |
| all currently registered IKE and ESP algorithms. | |
| - Fixed a bug in the ESP algorithm selection occurring when the strict flag | |
| is set and the first proposed transform does not match. | |
| - Fixed another deadlock in the use of the lock_certs_and_keys() mutex, | |
| occurring when a smartcard is present. | |
| - Prevented that a superseded Phase1 state can trigger a DPD_TIMEOUT event. | |
| - Fixed the printing of the notification names (null) | |
| - Applied another of Herbert Xu's Netlink patches. | |
| strongswan-2.2.0 | |
| ---------------- | |
| - Support of Dead Peer Detection. The connection parameter | |
| dpdaction=clear|hold | |
| activates DPD for the given connection. | |
| - The default Opportunistic Encryption (OE) policy groups are not | |
| automatically included anymore. Those wishing to activate OE can include | |
| the policy group with the following statement in ipsec.conf: | |
| include /etc/ipsec.d/examples/oe.conf | |
| The default for [right|left]rsasigkey is now set to %cert. | |
| - strongSwan now has a Vendor ID of its own which can be activated | |
| using the compile option VENDORID | |
| - Applied Herbert Xu's patch which sets the compression algorithm correctly. | |
| - Applied Herbert Xu's patch fixing an ESPINUDP problem | |
| - Applied Herbert Xu's patch setting source/destination port numbers. | |
| - Reapplied one of Herbert Xu's NAT-Traversal patches which got | |
| lost during the migration from SuperFreeS/WAN. | |
| - Fixed a deadlock in the use of the lock_certs_and_keys() mutex. | |
| - Fixed the unsharing of alg parameters when instantiating group | |
| connection. | |
| strongswan-2.1.5 | |
| ---------------- | |
| - Thomas Walpuski made me aware of a potential DoS attack via | |
| a PKCS#7-wrapped certificate bundle which could overwrite valid CA | |
| certificates in Pluto's authority certificate store. This vulnerability | |
| was fixed by establishing trust in CA candidate certificates up to a | |
| trusted root CA prior to insertion into Pluto's chained list. | |
| - replaced the --assign option by the -v option in the auto awk script | |
| in order to make it run with mawk under debian/woody. | |
| strongswan-2.1.4 | |
| ---------------- | |
| - Split of the status information between ipsec auto --status (concise) | |
| and ipsec auto --statusall (verbose). Both commands can be used with | |
| an optional connection selector: | |
| ipsec auto --status[all] <connection_name> | |
| - Added the description of X.509 related features to the ipsec_auto(8) | |
| man page. | |
| - Hardened the ASN.1 parser in debug mode, especially the printing | |
| of malformed distinguished names. | |
| - The size of an RSA public key received in a certificate is now restricted to | |
| 512 bits <= modulus length <= 8192 bits. | |
| - Fixed the debug mode enumeration. | |
| strongswan-2.1.3 | |
| ---------------- | |
| - Fixed another PKCS#7 vulnerability which could lead to an | |
| endless loop while following the X.509 trust chain. | |
| strongswan-2.1.2 | |
| ---------------- | |
| - Fixed the PKCS#7 vulnerability discovered by Thomas Walpuski | |
| that accepted end certificates having identical issuer and subject | |
| distinguished names in a multi-tier X.509 trust chain. | |
| strongswan-2.1.1 | |
| ---------------- | |
| - Removed all remaining references to ipsec_netlink.h in KLIPS. | |
| strongswan-2.1.0 | |
| ---------------- | |
| - The new "ca" section allows to define the following parameters: | |
| ca kool | |
| cacert=koolCA.pem # cacert of kool CA | |
| ocspuri=http://ocsp.kool.net:8001 # ocsp server | |
| ldapserver=ldap.kool.net # default ldap server | |
| crluri=http://www.kool.net/kool.crl # crl distribution point | |
| crluri2="ldap:///O=Kool, C= .." # crl distribution point #2 | |
| auto=add # add, ignore | |
| The ca definitions can be monitored via the command | |
| ipsec auto --listcainfos | |
| - Fixed cosmetic corruption of /proc filesystem by integrating | |
| D. Hugh Redelmeier's freeswan-2.06 kernel fixes. | |
| strongswan-2.0.2 | |
| ---------------- | |
| - Added support for the 818043 NAT-Traversal update of Microsoft's | |
| Windows 2000/XP IPsec client which sends an ID_FQDN during Quick Mode. | |
| - A symbolic link to libcrypto is now added in the kernel sources | |
| during kernel compilation | |
| - Fixed a couple of 64 bit issues (mostly casts to int). | |
| Thanks to Ken Bantoft who checked my sources on a 64 bit platform. | |
| - Replaced s[n]printf() statements in the kernel by ipsec_snprintf(). | |
| Credits go to D. Hugh Redelmeier, Michael Richardson, and Sam Sgro | |
| of the FreeS/WAN team who solved this problem with the 2.4.25 kernel. | |
| strongswan-2.0.1 | |
| ---------------- | |
| - an empty ASN.1 SEQUENCE OF or SET OF object (e.g. a subjectAltName | |
| certificate extension which contains no generalName item) can cause | |
| a pluto crash. This bug has been fixed. Additionally the ASN.1 parser has | |
| been hardened to make it more robust against malformed ASN.1 objects. | |
| - applied Herbert Xu's NAT-T patches which fixes NAT-T under the native | |
| Linux 2.6 IPsec stack. | |
| strongswan-2.0.0 | |
| ---------------- | |
| - based on freeswan-2.04, x509-1.5.3, nat-0.6c, alg-0.8.1rc12 |
