Summary: HMAC files for FIPS-140-2 integrity in strongSwan
The package provides HMAC hash files for FIPS-140-2 integrity checks,
a config file disabling alternative algorithm implementations and a
_fipscheck helper script preforming the integrity checks before e.g.
"ipsec start" action is executed, when FIPS-140-2 compliant operation
mode is enabled.






* Mon Sep 27 2021 Bjørn Lie <>
  - Update to version 5.9.3:
    * Added AES-ECB, SHA-3 and SHAKE-256 support to the wolfssl
    * Added AES-CCM support to the openssl plugin (#353).
    * The x509 and the openssl plugins now consider the
      authorityKeyIdentifier, if available, before verifying
      signatures, which avoids unnecessary signature verifications
      after a CA key rollover if both CA certificates are loaded.
      The openssl plugin now does the same also for CRLs (the x509
      plugin already did).
    * The pkcs11 plugin better handles optional attributes like
      CKA_TRUSTED, which previously depended on a version check.
    * The NetworkManager backend (charon-nm) now supports using SANs
      as client identities, not only full DNs (#437).
    * charon-tkm now handles IKE encryption.
    * Send a MOBIKE update again if a a change in the NAT mappings is
      detected but the endpoints stay the same (e143a7d).
    * A deadlock in the HA plugin introduced with 5.9.2 has been
      fixed (#456).
    * DSCP values are now also set for NAT keepalives.
    * The ike_derived_keys() hook now receives more keys but in a
      different order (4e29d6f).
    * Converted most of the test case scenarios to the vici

* Mon Sep 07 2020 Jan Engelhardt <>
  - Update to release 5.9.0
    * Prefer AEAD algorithms for ESP; this puts AES-GCM in a default
      AEAD proposal in front of the previous default proposal.
    * If a connection fails after getting redirected, we now
      restart connecting to the original host, not the one
      redirected to.
    * For peers that don't send the EAP_ONLY_AUTHENTICATION notify
      but still expect to use EAP-only authentication, the
      charon.force_eap_only_authentication option can be enabled to
      force this type of authentication even on non-compliant
    * IPv6 virtual IPs are now always enumerated, ignoring the
      charon.prefer_temporary_addrs setting, which should fix route
      installation if the latter is enabled.

  - Enable bypass-lan strongswan plugin
* Fri May 01 2020 Bjørn Lie <>
  - Update to version 5.8.4:
    * In IKEv1 Quick Mode make sure that a proposal exists before
      determining lifetimes (fixes a crash due to a null-pointer
      dereference in 5.8.3).
    * OpenSSL currently doesn't support squeezing bytes out of a
      SHAKE128/256 XOF (support was added with 5.8.3) multiple times.
      Unfortunately, EVP_DigestFinalXOF() completely resets the
      context and later calls not simply fail, they cause a
      null-pointer dereference in libcrypto. c5c1898d73 fixes the
      crash at the cost of repeating initializing the whole state and
      allocating too much data for subsequent calls (hopefully, once
      the OpenSSL issue 7894 is resolved we can implement this more
    * On 32-bit platforms, reading arbitrary 32-bit integers from
      config files (e.g. for charon.spi_min/max) has been fixed.
    * charon-nm now allows using fixed source ports.
  - Changes from version 5.8.3:
    * Updates for the NM plugin (and backend, which has to be updated
      to be compatible):
      + EAP-TLS authentication (#2097)
      + Certificate source (file, agent, smartcard) is selectable
      + Add support to configure local and remote identities (#2581)
      + Support configuring a custom server port (#625)
      + Show hint regarding password storage policy
      + Replaced the term "gateway" with "server"
      + Fixes build issues due to use of deprecated GLib
      + Updated Glade file to GTK 3.2
    * The NM backend now supports reauthentication and redirection.
    * Previously used reqids are now reallocated, which works around
      an issue on FreeBSD where the kernel doesn't allow the daemon
      to use reqids > 16383 (#2315).
    * On Linux, throw type routes are installed in table 220 for
      passthrough policies. The kernel will then fall back on routes
      in routing tables with lower priorities for matching traffic.
      This way, they require less information (e.g. no interface or
      source IP) and can be installed earlier and are not affected by
    * For IKEv1, the lifetimes of the actually selected transform are
      returned to the initiator, which is an issue if the peer uses
      different lifetimes for different transforms (#3329). We now
      also return the correct transform and proposal IDs (proposal ID
      was always 0, transform ID 1). IKE_SAs are now not
      re-established anymore (e.g. after several retransmits) if a
      deletion has been queued (#3335).
    * Added support for Ed448 keys and certificates via openssl
      plugin and pki tool.
    * Added support for SHA-3 and SHAKE128/256 in the openssl plugin.
    * The use of algorithm IDs from the private use range can now be
      enabled globally, to use them even if no strongSwan vendor ID
      was exchanged (05e373aeb0).
    * Fixed a compiler issue that may have caused invalid keyUsage
      extensions in certificates (#3249).
    * A lot of spelling fixes.
    * Fixed several reported issues.

  - Update to version 5.6.3 (CVE-2018-10811, boo#1093536,
    CVE-2018-5388, boo#1094462):
    * Fixed a DoS vulnerability in the IKEv2 key derivation if the
      openssl plugin is used in FIPS mode and HMAC-MD5 is negotiated
      as PRF. This vulnerability has been registered as
      CVE-2018-10811, boo#1093536.
    * Fixed a vulnerability in the stroke plugin, which did not check
      the received length before reading a message from the socket.
      Unless a group is configured, root privileges are required to
      access that socket, so in the default configuration this
      shouldn't be an issue. This vulnerability has been registered
      as CVE-2018-5388, boo#1094462.
    * CRLs that are not yet valid are now ignored to avoid problems
      in scenarios where expired certificates are removed from new
      CRLs and the clock on the host doing the revocation check is
      trailing behind that of the host issuing CRLs. Not doing this
      could result in accepting a revoked and expired certificate, if
      it's still valid according to the trailing clock but not
      contained anymore in not yet valid CRLs.
    * The issuer of fetched CRLs is now compared to the issuer of the
      checked certificate (#2608).
    * CRL validation results other than revocation (e.g. a skipped
      check because the CRL couldn't be fetched) are now stored also
      for intermediate CA certificates and not only for end-entity
      certificates, so a strict CRL policy can be enforced in such
    * In compliance with RFC 4945, section, certificates used
      for IKE must now either not contain a keyUsage extension (like
      the ones generated by pki), or have at least one of the
      digitalSignature or nonRepudiation bits set.
    * New options for vici/swanctl allow forcing the local
      termination of an IKE_SA. This might be useful in situations
      where it's known the other end is not reachable anymore, or
      that it already removed the IKE_SA, so retransmitting a DELETE
      and waiting for a response would be pointless.
    * Waiting only a certain amount of time for a response (i.e.
      shorter than all retransmits would be) before destroying the
      IKE_SA is also possible by additionally specifying a timeout in
      the forced termination request.
    * When removing routes, the kernel-netlink plugin now checks if
      it tracks other routes for the same destination and replaces
      the installed route instead of just removing it. Same during
      installation, where existing routes previously weren't
      replaced. This should allow using traps with virtual IPs on
      Linux (#2162).
    * The dhcp plugin now only sends the client identifier DHCP
      option if the identity_lease setting is enabled (7b660944b6).
      It can also send identities of up to 255 bytes length, instead
      of the previous 64 bytes (30e886fe3b, 0e5b94d038). If a server
      address is configured, DHCP requests are now sent from port 67
      instead of 68 to avoid ICMP port unreachables (becf027cd9).
    * The handling of faulty INVALID_KE_PAYLOAD notifies (e.g. one
      containing a DH group that wasn't proposed) during
      CREATE_CHILD_SA exchanges has been improved (#2536).
    * Roam events are now completely ignored for IKEv1 SAs (there is
      no MOBIKE to handle such changes properly).
    * ChaCha20/Poly1305 is now correctly proposed without key length
      (#2614). For compatibility with older releases the
      chacha20poly1305compat keyword may be included in proposals to
      also propose the algorithm with a key length (c58434aeff).
    * Configuration of hardware offload of IPsec SAs is now more
      flexible and allows a new setting (auto), which automatically
      uses it if the kernel and device both support it. If hw_offload
      is set to yes and offloading is not supported, the CHILD_SA
      installation now fails.
    * The kernel-pfkey plugin optionally installs routes via internal
      interface (one with an IP in the local traffic selector). On
      FreeBSD, enabling this selects the correct source IP when
      sending packets from the gateway itself (e811659323).
    * SHA-2 based PRFs are supported in PKCS#8 files as generated by
      OpenSSL 1.1 (#2574).
    * The pki --verify tool may load CA certificates and CRLs from
    * The IKE daemon now also switches to port 4500 if the remote
      port is not 500 (e.g. because the remote maps the response to a
      different port, as might happen on Azure), as long as the local
      port is 500 (85bfab621d).
    * Fixed an issue with DNS servers passed to NetworkManager in
      charon-nm (ee8c25516a).
    * Logged traffic selectors now always contain the protocol if
      either protocol or port are set (a36d8097ed).
    * Only the inbound SA/policy will be updated as reaction to IP
      address changes for rekeyed CHILD_SAs that are kept around.
    * The parser for strongswan.conf/swanctl.conf now accepts =
      characters in values without having to put the value in quotes
      (e.g. for Base64 encoded shared secrets).
  - Rename strongswan-5.6.2-rpmlintrc to strongswan-rpmlintrc,
    changing the version string on every version update makes no
* Tue Apr 17 2018
  - Update to version 5.6.2:
    * Fixed a DoS vulnerability in the parser for PKCS#1 RSASSA-PSS
      signatures that was caused by insufficient input validation.
      One of the configurable parameters in algorithm identifier
      structures for RSASSA-PSS signatures is the mask generation
      function (MGF). Only MGF1 is currently specified for this
      purpose. However, this in turn takes itself a parameter that
      specifies the underlying hash function. strongSwan's parser did
      not correctly handle the case of this parameter being absent,
      causing an undefined data read. This vulnerability has been
      registered as CVE-2018-6459.
    * When rekeying IKEv2 IKE_SAs the previously negotiated DH group
      will be reused, instead of using the first configured group,
      which avoids an additional exchange if the peer previously
      selected a different DH group via INVALID_KE_PAYLOAD notify.
      The same is also done when rekeying CHILD_SAs except for the
      first rekeying of the CHILD_SA that was created with the
      IKE_SA, where no DH group was negotiated yet. Also, the
      selected DH group is moved to the front in all sent proposals
      that contain it and all proposals that don't are moved to the
      back in order to convey the preference for this group to the
    * Handling of MOBIKE task queuing has been improved. In
      particular, the response to an address update (with NAT-D
      payloads) is not ignored anymore if only an address list update
      or DPD is queued as that could prevent updating the UDP
      encapsulation in the kernel.
    * On Linux, roam events may optionally be triggered by changes to
      the routing rules, which can be useful if routing rules
      (instead of e.g. route metrics) are used to switch from one to
      another interface (i.e. from one to another routing table).
      Since routing rules are currently not evaluated when doing
      route lookups this is only useful if the kernel-based route
      lookup is used (4664992f7d).
    * The fallback drop policies installed to avoid traffic leaks
      when replacing addresses in installed policies are now replaced
      by temporary drop policies, which also prevent acquires because
      we currently delete and reinstall IPsec SAs to update their
      addresses (35ef1b032d).
    * Access X.509 certificates held in non-volatile storage of a TPM
      2.0 referenced via the NV index.
    * Adding the --keyid parameter to pki --print allows to print
      private keys or certificates stored in a smartcard or a TPM
    * Fixed proposal selection if a peer incorrectly sends DH groups
      in the ESP proposal during IKE_AUTH and also if a DH group is
      configured in the local ESP proposal and
      charon.prefer_configured_proposals is disabled (d058fd3c32).
    * The lookup for PSK secrets for IKEv1 has been improved for
      certain scenarios (see #2497 for details).
    * MSKs received via RADIUS are now padded to 64 bytes to avoid
      compatibility issues with EAP-MSCHAPv2 and PRFs that have a
      block size < 64 bytes (e.g. AES-XCBC-PRF-128, see 73cbce6013).
    * The tpm_extendpcr command line tool extends a digest into a TPM
    * Ported the NetworkManager backend from the deprecated
      libnm-glib to libnm.
    * The save-keys debugging/development plugin saves IKE and/or ESP
      keys to files compatible with Wireshark.

* Tue Sep 05 2017
  - Updated to strongSwan 5.6.0 providing the following changes:
    * Fixed a DoS vulnerability in the gmp plugin that was caused by insufficient input validation
      when verifying RSA signatures, which requires decryption with the operation m^e mod n,
      where m is the signature, and e and n are the exponent and modulus of the public key.
      The value m is an integer between 0 and n-1, however, the gmp plugin did not verify this.
      So if m equals n the calculation results in 0, in which case mpz_export() returns NULL.
      This result wasn't handled properly causing a null-pointer dereference.
      This vulnerability has been registered as CVE-2017-11185. (bsc#1051222)
    * New SWIMA IMC/IMV pair implements the draft-ietf-sacm-nea-swima-patnc Internet
      Draft and has been demonstrated at the IETF 99 Prague Hackathon.
    * The IMV database template has been adapted to achieve full compliance with the
      ISO 19770-2:2015 SWID tag standard.
    * The pt-tls-client can attach and use TPM 2.0 protected private keys via the --keyid parameter.
    * By default the /etc/swanctl/conf.d directory is created and *.conf files in it are included in the default
      swanctl.conf file.
    * The curl plugin now follows HTTP redirects (configurable via strongswan.conf).
    * The CHILD_SA rekeying was fixed in charon-tkm and the behavior is refined a bit more since 5.5.3
    * libtpmtss supports Intel's TSS2 Architecture Broker and Resource Manager interface (tcti-tabrmd).

  - fix "uintptr_t’ undeclared" compilation error.
* Mon Jul 31 2017
  - Updated to strongSwan 5.3.5(bsc#1050691) providing the following changes:
    * Fixed a DoS vulnerability in the gmp plugin that was caused by insufficient input
      validation when verifying RSA signatures. More specifically, mpz_powm_sec() has two
      requirements regarding the passed exponent and modulus that the plugin did not
      enforce, if these are not met the calculation will result in a floating point exception
      that crashes the whole process.
      This vulnerability has been registered as CVE-2017-9022.
      Please refer to our blog for details.
    * Fixed a DoS vulnerability in the x509 plugin that was caused because the ASN.1 parser
      didn't handle ASN.1 CHOICE types properly, which could result in an infinite loop when
      parsing X.509 extensions that use such types.
      This vulnerability has been registered as CVE-2017-9023.
      Please refer to our blog for details.
    * The behavior during IKEv2 CHILD_SA rekeying has been changed in order to avoid
      traffic loss. When responding to a CREATE_CHILD_SA request to rekey a CHILD_SA
      the responder already has everything available to install and use the new CHILD_SA.
      However, this could lead to lost traffic as the initiator won't be able to process
      inbound packets until it processed the CREATE_CHILD_SA response and updated the
      inbound SA. To avoid this the responder now only installs the new inbound SA and
      delays installing the outbound SA until it receives the DELETE for the replaced CHILD_SA.
    * The messages transporting these DELETEs could reach the peer before packets sent
      with the deleted outbound SAs reach it. To reduce the chance of traffic loss due
      to this the inbound SA of the replaced CHILD_SA is not removed for a configurable
      amount of seconds (charon.delete_rekeyed_delay) after the DELETE has been processed.
    * The code base has been ported to Apple's ARM64 iOS platform, which required several
      changes regarding the use of variadic functions. This was necessary because the calling
      conventions for variadic and regular functions are different there.
      This means that assigning a non-variadic function to a variadic function pointer, as we
      did with our enumerator_t::enumerate() implementations and several callbacks, will
      result in crashes as the called function accesses the arguments differently than the
      caller provided them. To avoid this issue the enumerator_t interface has been changed
      and the signature of the callback functions for enumerator_create_filter() and two
      methods on linked_list_t have been changed. Refer to the developer notes below
      for details.
    * Adds support for fuzzing the certificate parser provided by the default plugins
      (x509, pem, gmp etc.) on Google's OSS-Fuzz infrastructure (or generally with
      libFuzzer). Several issues found while fuzzing these plugins were fixed.
    * Two new options have been added to charon's retransmission settings:
      retransmit_limit and retransmit_jitter. The former adds an upper limit to the
      calculated retransmission timeout, the latter randomly reduces it.
      Refer to Retransmission for details.
    * A bug in swanctl's --load-creds command was fixed that caused unencrypted
      private keys to get unloaded if the command was called multiple times.
      The load-key VICI command now returns the key ID of the loaded key on success.
    * The credential manager now enumerates local credential sets before global ones.
      This means certificates supplied by the peer will now be preferred over certificates
      with the same identity that may be locally stored (e.g. in the certificate cache).
    * Adds support for hardware offload of IPsec SAs as introduced by Linux 4.11 for
      specific hardware that supports this.
    * The pki tool loads the curve25519 plugin by default.

* Mon Jul 04 2016
  - Updated to strongSwan 5.3.5 providing the following changes:
    Changes in version 5.3.5:
    * Properly handle potential EINTR errors in sigwaitinfo(2) calls
      that replaced sigwait(3) calls with 5.3.4.
    * RADIUS retransmission timeouts are now configurable, courtesy
      of Thom Troy.
    Changes in version 5.3.4:
    * Fixed an authentication bypass vulnerability in the
      eap-mschapv2 plugin that was caused by insufficient
      verification of the internal state when handling MSCHAPv2
      Success messages received by the client. This vulnerability
      has been registered as CVE-2015-8023.
    * The sha3 plugin implements the SHA3 Keccak-F1600 hash
      algorithm family. Within the strongSwan framework SHA3 is
      currently used for BLISS signatures only because the OIDs for
      other signature algorithms haven't been defined yet. Also the
      use of SHA3 for IKEv2 has not been standardized yet.
    Changes in version 5.3.3:
    * Added support for the ChaCha20/Poly1305 AEAD cipher specified
      in RFC 7539 and RFC 7634 using the chacha20poly1305 ike/esp
      proposal keyword. The new chapoly plugin implements the
      cipher, if possible SSE-accelerated on x86/x64 architectures.
      It is usable both in IKEv2 and the strongSwan libipsec ESP
      backend. On Linux 4.2 or newer the kernel-netlink plugin can
      configure the cipher for ESP SAs.
    * The vici interface now supports the configuration of auxiliary
      certification authority information as CRL and OCSP URIs.
    * In the bliss plugin the c_indices derivation using a SHA-512
      based random oracle has been fixed, generalized and
      standardized by employing the MGF1 mask generation function
      with SHA-512. As a consequence BLISS signatures unsing the
      improved oracle are not compatible with the earlier
    * Support for auto=route with right=%any for transport mode
      connections has been added (the ikev2/trap-any scenario
      provides examples).
    * The starter daemon does not flush IPsec policies and SAs
      anymore when it is stopped. Already existing duplicate
      policies are now overwritten by the IKE daemon when it
      installs its policies.
    * Init limits (like charon.init_limit_half_open) can now
      optionally be enforced when initiating SAs via VICI. For this,
      IKE_SAs initiated by the daemon are now also counted as half
      open SAs, which, as a side-effect, fixes the status output
      while connecting (e.g. in ipsec status).
    * Symmetric configuration of EAP methods in left|rightauth is
      now possible when mutual EAP-only authentication is used
      (previously, the client had to configure rightauth=eap or
      rightauth=any, which prevented it from using this same config
      as responder).
    * The initiator flag in the IKEv2 header is compared again
      (wasn't the case since 5.0.0) and packets that have the flag
      set incorrectly are again ignored.
    * Implemented a demo Hardcopy Device IMC/IMV pair based on the
      "Hardcopy Device Health Assessment Trusted Network Connect
      Binding" (HCD-TNC) document drafted by the IEEE Printer
      Working Group (PWG).
    * Fixed IF-M segmentation which failed in the presence of
      multiple small attributes in front of a huge attribute to be
    Changes in version 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.
    Changes in version 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
    * 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.
    Changes in version 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.

* Mon Jan 05 2015
  - Updated to strongSwan 5.2.2 providing the following changes:
    Changes in version 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.
    Changes in version 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.
    Changes in version 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 ( 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
    * The ipsec.conf replay_window option defines connection specific IPsec
      replay windows. Original patch courtesy of Zheng Zhong and Christophe
      Gouault from 6Wind.

  - Updated to strongSwan 5.1.3 providing the following changes:
    - 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.
      (CVE-2014-2338, bnc#870572).
    - 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.
    - Fixed an issue where CRL/OCSP trustchain validation broke enforcing
      CA constraints
    - Limited OCSP signing to specific certificates to improve performance
    - authKeyIdentifier is not added to self-signed certificates anymore
    - Fixed the comparison of IKE configs if only the cipher suites were
* Wed Apr 02 2014
  - Updated to strongSwan 5.1.2 providing the following changes:
    - 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. 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 in order to use NTRU
      (charon.send_vendor_id = yes).
    - 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.
* Fri Nov 01 2013
  - Updated to strongSwan 5.1.1 minor release addressing two security
    fixes (bnc#847506,CVE-2013-6075, bnc#847509,CVE-2013-6076):
    - 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
    - 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.
  - Adjusted file lists: this version installs the pki utility and manuals
    in common /usr directories and additional ipsec/pt-tls-client helper.
* Mon Aug 05 2013
  - Updated to strongSwan 5.1.0 release (bnc#833278, CVE-2013-5018):
    - 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
    - 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
    - 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.
* Tue Apr 30 2013
  - Updated to strongSwan 5.0.4 release (bnc#815236, CVE-2013-2944):
    - 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. Refer to our
      blog for details.
    - 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 strongswan.conf option causes charon to
      ignore IKE initiation requests.
    - The openssl plugin can now use the openssl-fips library.
    The version 5.0.3 provides new ipseckey plugin, enabling authentication
    based on trustworthy public keys stored as IPSECKEY resource records in
    the DNS and protected by DNSSEC and new openssl plugin using the AES-NI
    accelerated version of AES-GCM if the hardware supports it.
    for a list of all changes since the 5.0.1 release.
* Thu Nov 29 2012
  - Verify GPG signature.
* Fri Nov 16 2012
  - Fix systemd unit dir
* Wed Oct 31 2012
  - Updated to strongSwan 5.0.1 release. Changes digest:
    - 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.
    - The xauth-pam backend can authenticate IKEv1 XAuth and Hybrid
      authenticated clients against any PAM service.
    - The new unity plugin brings support for some parts of the IKEv1
      Cisco Unity Extensions.
    - The kernel-netlink plugin supports the new strongswan.conf option
    - Job handling in controller_t was fixed, which occasionally caused
      crashes on ipsec up/down.
    - Fixed transmission EAP-MSCHAPv2 user name if it contains a domain
    Changes digest from strongSwan 5.0.0 version:
    * The charon IKE daemon gained experimental support for the IKEv1
      protocol. Pluto has been removed from the 5.x series.
    * The NetworkManager charon plugin of previous releases is now
      provided by a separate executable (charon-nm) and it should work
      again with NM 0.9.
    * scepclient was updated and it now works fine with Windows Server
      2008 R2.
    For full list of the changes, please read the NEWS file shipped
    in the strongswan-doc package or online:
  - Adopted spec file, enabled several plugins, e.g.: ccm, certexpire,
    coupling, ctr, duplicheck, eap-dynamic, eap-peap, eap-tls, eap-tnc,
    eap-ttls, gcm, nonce, radattr, tnc, tnccs, unity, xauth-eap and pam.
  - Changed to install strongswan.service with alias to ipsec.service
    instead of the /etc/init.d/ipsec init script on openSUSE > 12.2.
* Fri Sep 07 2012
  - Applied upstream patch adjusting an internal thread id causing
    charon keying daemon start failure (bnc#779038,strongswan#198):
      openssl: Ensure the thread ID is never zero
      This might otherwise cause problems because OpenSSL tries to
      lock mutexes recursively if it assumes the lock is held by a
      different thread e.g. during FIPS initialization.
    See for more informations.
* Thu May 31 2012
  - Updated to strongSwan 4.6.4 release:
    - 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
      (bnc#761325, CVE-2012-2388).
    - Fixed several issues with reauthentication and address updates.
* Thu May 10 2012
  - Updated to strongSwan 4.6.3 release:
    - 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.
    - The farp plugin sends ARP responses for any tunneled address,
      not only virtual IPs.
    - Charon resolves hosts again during additional keying tries.
    - Fixed switching back to original address pair during MOBIKE.
    - When resending IKE_SA_INIT with a COOKIE charon reuses the previous
      DH value, as specified in RFC 5996.
      This has an effect on the lifecycle of diffie_hellman_t, see
      source:src/libcharon/sa/keymat.h#39 for details.
    - COOKIEs are now kept enabled a bit longer to avoid certain race
      conditions the commit message to 1b7debcc has some details.
    - The new stroke user-creds command allows to set username/password
      for a connection.
    - strongswan.conf option added to set identifier for syslog(3) logging.
    - Added a workaround for null-terminated XAuth secrets (as sent by
      Android 4).
* Sat Mar 03 2012
  - Updated to strongSwan 4.6.2 release:
    Changes in 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.
* Wed Feb 15 2012
  - Updated to strongSwan 4.6.1 release:
    Changes in 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
      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.
    Changes in 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.
  - Merged patches, changed strongswan-doc to be a noarch package.
  - Fixed rpmlint runlevel & fsf warnings, updated rpmlintrc
* Mon Feb 06 2012
  - Only glib.h can be included, fix compilation.
* Wed Dec 21 2011
  - remove call to suse_update_config (very old work around)
* Mon Sep 12 2011
  - remove _service file, too fragile
* Mon Sep 12 2011
  - Fixed version in last changelog entry
* Thu Sep 08 2011
  - Updated to strongSwan 4.5.3 release, changes overview since 4.5.2:
    * 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
    * 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).
    * 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 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
    * 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.
    * IMC/IMV Test pair implementing the RFC 5792 PA-TNC (IF-M) protocol.
    * 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.
  - Fixed some fmt warnings in libchecksum, adopted paths in the spec file
* Sun May 29 2011
  - Updated to strongSwan 4.5.2 release, changes overview since 4.5.1:
    * 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.
    * 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.
* Mon Mar 14 2011
  - Updated to strongSwan 4.5.1 release, changes overview since 4.5.0:
    * Implements RFC 5793 Posture Broker Protocol (BP)
    * Re-implemented TNCCS 1.1 protocol
    * Allows to store IKE and ESP proposals in an SQL database
    * Allows to store CRL and OCSP cert points in an SQL database
    * New 'include' statement in strongswan.conf allows recursions
    * Modifications of strongswan.conf parser, cause syntax attr plugin
      syntax changes.
    * ipsec listalgs now appends the plugin registering an algo
    * Adds support for Traffic Flow Confidentiality with Linux 2.6.38
    * New af-alg plugin allows to use new primitives in 2.6.38 crypto api
      and removes the need for additional userland implementations.
    * IKEv2 daemon supports the INITIAL_CONTACT notify
    * conftest conformance testing framework
    * new constraints plugin provides advanced X.509 constraint checking
    * left/rightauth ipsec.conf keywords accept minimum strengths
    * basic support for delta CRLs
    See the NEWS file or
    for a detailed description of the changes.
* Mon Nov 22 2010
  - Cleaned up spec file; use with_mysql,sqlite,gcrypt,nm flags
  - Disabled tests sub-package with load-tester and test-vectors
    plugins by default using a with_tests flag (causes load error
    in "ipsec pki" when enabled but the package is not installed).
* Tue Nov 16 2010
  - Updated to strongSwan 4.5.0 release, changes since 4.4.1 are:
    * 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.
    * 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
  - Adopted spec file, removed obsolete error range patch.
* Tue Aug 10 2010
  - Updated to strongSwan 4.4.1 release, changes since 4.4.0 are:
    * 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.
  - Removed obsolete snprintf security fix, adopted spec file
  - Enabled the eap-sim,eap-sim-file,eap-simaka-sql,eap-simaka-reauth,
    eap-simaka-pseudonym,eap-aka-3gpp2,md4,blowfish,addrblock plugins.
  - Enabled the mysql, sqlite, load-tester and test-vectors plugins,
    that are packaged into separate mysql,sqlite,tests sub packages.
  - Disabled sqlite plugin on SLE-10 -- sqlite3 lib is too old there.
  - Applied patch by Jiri Bohac fixing error-type range in parsing of
    NOTIFY payloads (RFC 4306, section 3.10.1).
* Fri Jul 02 2010
  - Applied upstream patch fixing snprintf flaws in the strongSwan
    IKE daemons exploitable by unauthenticated attackers using a
    crafted certificate or identification payload (bnc#615915).
* Fri Jul 02 2010
  - Added README.SUSE to source list in the spec file.
* Fri May 14 2010
  - Updated to strongSwan 4.4.0 release, changes since 4.3.6 are:
    * 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
    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 her 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.
  - Splitted package into strongswan-ipsec, that install the traditional
    ipsec service starter scripts, -ikev1 and -ikev2 installing daemons
    and -libs0, that contains the library and plugins.
  - Enabled dhcp, farp, ha, socket-dynamic, agent, eap and sql plugins.
  - Enabled NetworkManager nm plugin in a separate strongswan-nm package.
* Tue Mar 02 2010
  - Updated to strongSwan 4.3.6 release, changes since 4.3.4 are:
    * 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
    * 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
    * Fixed BEET mode connections on recent kernels by installing SAs
    with appropriate traffic selectors, based on a patch by Michael
    * 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.
    * 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.
  - Removed obsolete load_secrets patches, refreshed modprobe patch.
  - Corrected a time_t cast reported by rpmlint (timer.c:51)
  - Disabled libtoolize call and the gcrypt plugin on SLE 10.
* Fri Sep 04 2009
  - Fixed open failure debug message in load_secrets
* Thu Sep 03 2009
  - Applied patch fixing locking in ipsec.secrets inclusion.
* Mon Aug 31 2009
  - Updated to strongSwan 4.3.4 release:
    * IKEv2 charon daemon ported to FreeBSD and Mac OS X. Installation
      details can be found on
    * 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.
  - Removed obsolete ipsec.secrets include patch (bnc#524799)
    and patch to avoid libchecksum version.
* Fri Aug 07 2009
  - Applied patch implementing ipsec.secrets "include" directive
    support in charon (,
* Mon Jul 27 2009
  - Updated to strongSwan 4.3.3 release:
    * 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.
  - Enabled --enable-integrity-test configure option (new feature).
  - Removed patch to avoid plugin versions (accepted by upstream)
    and added patch to avoid version for new libchecksum library.
  - Added -Wno-pointer-sign -Wno-strict-aliasing CFLAGS in the spec.
* Wed Jun 10 2009
  - Updated to strongSwan 4.3.2 release, that fixes two asn1 parser
    DoS vulnerabilities and provides several new features, e.g.:
    * 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.
    * 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
    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 developped 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.
  - Enabled new gcrypt plugin
  - Adopted spec file and modprobe to syslog patch
  - Removed obsolete getline glibc collision patch
  - Added patch to avoid library version for plugins (rpmlint).
  - Replaced update-dns-server patch with a --with-resolv-conf.
  - Removed restart_on_update from spec file (see bnc#450390).
* Sun Jun 07 2009
  - rename getline to my_getline to avoid collision with function
    from glibc
* Tue Jun 02 2009
  - Applied fix for a Denial-of-Service vulnerability where receiving
    a malformed IKE_SA_INIT request leaves an incomplete state which
    causes a crash of the IKEv2 charon while dereferencing a NULL
    pointer if a subsequent CREATE_CHILD_SA is received (bnc#507742).
  - Applied fix for a Denial-of-Service vulnerability where receiving
    a malformed IKE_AUTH request with either a missing TSi or TSr
    traffic selector payload causes a crash of the IKEv2 charon while
    dereferencing a NULL pointer because the NULL pointer checks of
    TSi and TSr before destruction were erroneously swapped
* Tue Mar 31 2009
  - Updated to strongSwan 4.2.14 release that fixes a grave DPD
    denial of service vulnerability registered as CVE-2009-0790,
    that had been slumbering in the code for many years:
    * A vulnerability in the Dead Peer Detection (RFC 3706) code
      was found by Gerd v. Egidy <> 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
    * The new server-side EAP RADIUS plugin (--enable-eap-radius)
      relays EAP messages to and from a RADIUS server. Succesfully
      tested with with a freeradius server using EAP-MD5 and EAP-SIM.
    * 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.
* Mon Oct 20 2008
  - Updated to 4.2.8 release:
    * 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
    * 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.
* Tue Oct 14 2008
  - Applied fix for addr_in_subnet() extracted from strongswan-4.2.8
    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.
* Fri Oct 10 2008
  - Applied fix for 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 Multi Precision
    (GMP) library. Thanks go to Mu Dynamics Research Labs for making
    us aware of this problem. (bnc#435194)
* Thu Aug 28 2008
  - Fixed to use --enable-curl instead of --enable-http as before
  - Enabled the OpenSSL crypto plugin in the spec file.
* Thu Aug 28 2008
  - Updated to 4.2.6 release, fixing bugs and offering a lot of new
    features comparing to the last version provided by this package.
    Most important are:
    * 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.
    * 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.
    * 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
    * 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.
    * The openssl plugin supports the elliptic curve Diffie-Hellman
    groups 19, 20, 21, 25, and 26 and 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
    * ESP sequence numbers are now migrated in IPsec SA updates handled
    by MOBIKE. Works only with Linux kernels >= 2.6.17.
    * Fixed a number of minor bugs that where discovered during the 4th
    IKEv2 interoperability workshop in San Antonio, TX.
    * 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.
  - Added patch disabling direct modifications of resolv.conf; has to
    be replaced by a netconfig call.
  - Added patch adding a missed file name argument in printf call in the
    scripts/thread_analysis.c file -- resulting binary is not installed.
  - Removed obsolete patches crash_badcfg_reload and old-caps-version.
* Mon Jun 30 2008
  - Added fix that explicitly enables version 1 linux capabilities
    on version 2 systems to aviod that the charon and pluto daemons
    exit because of failed capset call (bnc#404989).
* Mon May 19 2008
  - Applied fix (strongswan_crash_badcfg_reload.dif) to avoid
    a crash after reloading with bad config (bnc#392062).
* Wed Apr 23 2008
  - Updated to 4.2.1 release. A lot of code refactoring in the 4.2
    release provides much more modularity and therefore much more
    extensiblity and offers the following new features:
    * libstrongswan has been modularized to attach crypto algorithms,
    credential implementations (secret and private keys, certificates)
    and http/ldap fetchers dynamically through plugins.
    * A relational database API that uses pluggable database providers
    was added to libstrongswan including plugins for MySQL and SQLite.
    * The IKEv2 keying charon daemon has become more extensible. Generic
    plugins can provide arbitrary interfaces to credential stores and
    connection management interfaces. Also any EAP method can be added.
    * 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.
    * Support for "Hash and URL" encoded certificate payloads has been
    implemented in the IKEv2 daemon charon.
    * The IKEv2 daemon charon now supports the "uniqueids" option to
    close multiple IKE_SAs with the same peer.
    * The crypto factory in libstrongswan additionally supports random
    number generators. Plugins may provide other sources of randomness.
    * Extended the credential framework by a caching option to allow
    plugins persistent caching of fetched credentials.
    * The new trust chain 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 simple pool defined in ipsec.conf.
    * Fixed compilation on uClibc and a couple of other minor bugs.
    * 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.
  - Applied a small patch defining _GNU_SOURCE for struct in6_pktinfo
    and adding inclusion of limits.h for PATH_MAX availability.
  - Added rpmlintrc file and a libtoolize call to the spec file.
* Tue Feb 19 2008
  - Updated to 4.1.11 maintenance release, providing following fixes:
    * 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'.
  - The 4.1.10 final version, declared upstream as "Fully tested support
    of IPv6 IPsec tunnel connections", fixes ordering error in oscp cache,
    IPv6 defaults of the nexthop parameter, adds support for new EAP
    modules [disabled in this build] and obsoletes our strongswan_path
    and strongswan_ipsec_script_msg patches.
  - Removed a sed call from init script.
* Sat Dec 08 2007
  - Updated to 4.1.9 final, including all our patches.
  - Changed init script to use ipsec cmd using LSB codes now.
  - Added strongswan_path.dif setting a PATH in scripts (updown).
  - Added strongswan_ipsec_script_msg.dif for consistent look of
    ipsec script messages.
  - Added strongswan_modprobe_syslog.dif redirecting modprobe
    output to syslog.
* Mon Nov 26 2007
  - Renamed charon plugins to avoid rpm conflicts with existing
    libraries (libstroke). Patch: strongswan-libconflicts.dif
  - Added init script. Template file:
* Thu Nov 22 2007
  - Initial, unfinished package
