- 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
  CHILD SA.
  The command ipsec down <conn>{n} deletes CHILD SA instance n of
  connection <conn> whereas ipsec down <conn>{*} deletes all CHILD
  SA instances.
  The command ipsec down <conn>[n] deletes IKE SA instance n of
  connection <conn> plus dependent CHILD SAs whereas ipsec down
  <conn>[*] deletes all IKE SA instances of connection <conn>.
  * Fixed a regression introduced in 4.3.0 where EAP authentication
  calculated the AUTH payload incorrectly. Further, the EAP-MSCHAPv2
  MSK key derivation has been updated to be compatible with the
  Windows 7 Release Candidate.
  * Refactored installation of triggering policies. Routed policies
  are handled outside of IKE_SAs to keep them installed in any case.
  A tunnel gets established only once, even if initiation is delayed
  due network outages.
  * Improved the handling of multiple acquire signals triggered by
  the kernel.
  * Fixed two DoS vulnerabilities in the charon daemon that were
  discovered by fuzzing techniques:
  1) Sending a malformed IKE_SA_INIT request leaved an incomplete
  state which caused a null pointer dereference if a subsequent
  CREATE_CHILD_SA request was sent.
  2) Sending an IKE_AUTH request with either a missing TSi or TSr
  payload caused a null pointer derefence because the checks for
  TSi and TSr were interchanged.
  The IKEv2 fuzzer used was 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).

-------------------------------------------------------------------
Mon Jun  8 00:21:13 CEST 2009 - ro@suse.de

- rename getline to my_getline to avoid collision with function
  from glibc 

-------------------------------------------------------------------
Tue Jun  2 09:56:16 CEST 2009 - mt@suse.de

- 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
  (bnc#507742).

-------------------------------------------------------------------
Tue Mar 31 11:19:03 CEST 2009 - mt@suse.de

- 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 <gerd.von.egidy@intra2net.com> of
    Intra2net AG affecting all Openswan and strongSwan releases.
    A malicious (or expired ISAKMP) R_U_THERE or R_U_THERE_ACK
    Dead Peer Detection packet can cause the pluto IKE daemon to
    crash and restart. No authentication or encryption is required
    to trigger this bug. One spoofed UDP packet can cause the pluto
    IKE daemon to restart and be unresponsive for a few seconds
    while restarting. This DPD null state vulnerability has been
    officially registered as CVE-2009-0790 and is fixed by this
    release.
  * 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 09:27:06 CEST 2008 - mt@suse.de

- 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
  interface.
  * Several MOBIKE improvements: Detect changes in NAT mappings in
  DPD exchanges, handle events if kernel detects NAT mapping changes
  in UDP-encapsulated ESP packets (requires kernel patch), reuse old
  addesses in MOBIKE updates as long as possible and other fixes.
  * Fixed a bug in addr_in_subnet() which caused insertion of wrong
  source routes for destination subnets having netwmasks not being a
  multiple of 8 bits.  Thanks go to Wolfgang Steudel, TU Ilmenau for
  reporting this bug.

-------------------------------------------------------------------
Tue Oct 14 16:29:59 CEST 2008 - mt@suse.de

- 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.
  (bnc#435200)

-------------------------------------------------------------------
Fri Oct 10 08:08:35 CEST 2008 - mt@suse.de

- 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 14:31:49 CEST 2008 - mt@suse.de

- Fixed to use --enable-curl instead of --enable-http as before
- Enabled the OpenSSL crypto plugin in the spec file.

-------------------------------------------------------------------
Thu Aug 28 09:48:14 CEST 2008 - mt@suse.de

- 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
  strongswan.conf.
  * The XFRM_STATE_AF_UNSPEC flag added to xfrm.h allows IPv4-over-IPv6
  and IPv6-over-IPv4 tunnels with the 2.6.26 and later Linux kernels.
  * management of different virtual IP pools for different network
  interfaces have become possible.
  * fixed a bug which prevented the assignment of more than 256
  virtual IP addresses from a pool managed by an sql database.
  * fixed a bug which did not delete own IPCOMP SAs in the kernel.
  * 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
  socket.
  * 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 22:40:31 CEST 2008 - mt@suse.de

- 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 16:17:16 CEST 2008 - mt@suse.de

- Applied fix (strongswan_crash_badcfg_reload.dif) to avoid
  a crash after reloading with bad config (bnc#392062).

-------------------------------------------------------------------
Wed Apr 23 14:28:41 CEST 2008 - mt@suse.de

- 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 11:44:03 CET 2008 - mt@suse.de

- 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  8 13:03:42 CET 2007 - mt@suse.de

- 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 10:19:40 CET 2007 - mt@suse.de

- Renamed charon plugins to avoid rpm conflicts with existing
  libraries (libstroke). Patch: strongswan-libconflicts.dif
- Added init script. Template file: strongswan.init.in

-------------------------------------------------------------------
Thu Nov 22 10:25:56 CET 2007 - mt@suse.de

- Initial, unfinished package
