- Version 5.8.2
===============
* Identity-based CA constraints, which enforce that the certificate chain of the remote
peer contains a CA certificate with a specific identity, are supported via
vici/swanctl.conf. This is similar to the existing CA constraints but doesn't require
that the CA certificate is locally installed, for instance, intermediate CA certificates
received from the peers. Wildcard identity matching (e.g. ..., OU=Research, CN=*) could
also be used for the latter but requires trust in the intermediate CAs to only issue
certificates with legitimate subject DNs (e.g. the "Sales" CA must not issue certificates
with OU=Research). With the new constraint that's not necessary as long as a path length
basic constraint (--pathlen for pki --issue) prevents intermediate CAs from issuing further
intermediate CAs.
* Intermediate CA certificates may now be sent in hash-and-URL encoding by configuring a
base URL for the parent CA (#3234, swanctl/rw-hash-and-url-multi-level).
* Implemented NIST SP-800-90A Deterministic Random Bit Generator (DRBG) based on AES-CTR
and SHA2-HMAC modes. Currently used by the gmp and ntru plugins.
* Random nonces sent in an OCSP requests are now expected in the corresponding OCSP responses.
* The kernel-netlink plugin now ignores deprecated IPv6 addresses for MOBIKE. Whether temporary
or permanent IPv6 addresses are included now depends on the charon.prefer_temporary_addrs
setting (#3192).
* Extended Sequence Numbers (ESN) are configured via PF_KEY if supported by the kernel.
* The PF_KEY socket's receive buffer in the kernel-pfkey plugin is now cleared before sending
requests, as many of the messages sent by the kernel are sent as broadcasts to all PF_KEY
sockets. This is an issue if an external tool is used to manage SAs/policies unrelated to
IPsec (#3225).
* The vici plugin now uses unique section names for CHILD_SAs in child-updown events (7c74ce9190).
* For individually deleted CHILD_SAs (in particular for IKEv1) the vici child-updown event
now includes more information about the CHILD_SAs such as traffic statistics (#3198).
* Custom loggers are correctly re-registered if log levels are changed via stroke loglevel (#3182).
* Avoid lockups during startup on low entropy systems when using OpenSSL 1.1.1 (095a2c2eac).
* Instead of failing later when setting a key, creating HMACs via openssl plugin now fails
instantly if the underlying hash algorithm isn't supported (e.g. MD5 in FIPS-mode) so fallbacks
to other plugins work properly (#3284).
* Exponents of RSA keys read from TPM 2.0 via SAPI are correctly converted (8ee1242f1438).
* Routing table IDs > 255 are supported for custom routes on Linux.
* To avoid races, the check for hardware offloading support in the kernel-netlink plugin is
performed during initialization of the plugin (a605452c03).
* The D-Bus config file for charon-nm is now installed in $(datadir)/dbus-1/system.d instead of
$(sysconfdir)/dbus-1/system.d, which is intended for sysadmin overrides.
INVALID_MAJOR_VERSION notifies are now correctly sent in messages of the same exchange type
and with the same message ID as the request.
* IKEv2 SAs are now immediately destroyed when sending or receiving INVALID_SYNTAX notifies
in authenticated messages.
* For developers working from the repository the configure script now aborts if GNU gperf is
not found.
- Version 5.8.1
===============
* RDNs in DNs of X.509 certificates can now optionally be matched less strict. The global
strongswan.conf option charon.rdn_matching takes two alternative values that cause the
matching algorithm to either ignore the order of matched RDNs (reordered) or additionally
(relaxed) accept DNs that contain more RDNs than configured (unmatched RDNs are treated
like wildcard matches).
* The updown plugin now passes the same interface to the script that is also used for the
automatically installed routes, that is, the interface over which the peer is reached
instead of the interface on which the local address is found (#3095).
* TPM 2.0 contexts are now protected by a mutex to prevent issues if multiple IKE_SAs use
the same private key concurrently (4b25885025).
* Do a rekey check after the third QM message was received (#3060).
* If available, explicit_bzero() is now used as memwipe() instead of our own implementation.
* An .editorconfig file has been added, mainly so Github shows files with proper indentation
(68346b6962).
* The internal certificate of the load-tester plugin has been modified so it can again be
used as end-entity cert with 5.6.3 and later (#3139).
* The maximum data length of received COOKIE notifies (64 bytes) is now enforced (#3160).
- Version 5.8.0
===============
* The systemd service units have been renamed. The modern unit, which was called
strongswan-swanctl, is now called strongswan (the previous name is configured as alias in
the unit, for which a symlink is created when the unit is enabled). The legacy unit is now
called strongswan-starter.
* Support for XFRM interfaces (available since Linux 4.19) has been added, which are intended
to replace VTI devices (they are similar but offer several advantages, for instance, they
are not bound to an address or address family).
* IPsec SAs and policies are associated with such interfaces via interface IDs that can be
configured in swanctl.conf (dynamic IDs may optionally be allocated for each SA and even
direction). It's possible to use separate interfaces for in- and outbound traffic (or
only use an interface in one direction and regular policies in the other).
* Interfaces may be created dynamically via updown/vici scripts, or statically before or after
establishing the SAs. Routes must be added manually as needed (the daemon will not install
any routes for outbound policies with an interface ID).
* When moving XFRM interfaces to other network namespaces they retain access to the SAs and
policies installed in the original namespace, which allows providing IPsec tunnels for
processes in other network namespaces without giving them access to the IPsec keys or
IKE credentials.
More information can be found on the page about route-based VPNs.
* Initiation of childless IKE_SAs is supported (RFC 6023). If enabled and supported by the
responder, no CHILD_SA is established during IKE_AUTH. Instead, all CHILD_SAs are created
with CREATE_CHILD_SA exchanges. This allows using a separate DH exchange even for the
first CHILD_SA, which is otherwise created during IKE_AUTH with keys derived from the
IKE_SA's key material.
* The swanctl --initiate command may be used to initiate only the IKE_SA via --ike
option if --child is omitted and the peer supports this extension.
* The NetworkManager backend and plugin support IPv6.
* The new wolfssl plugin is a wrapper around the wolfSSL crypto library. Thanks to Sean
Parkinson of wolfSSL Inc. for the initial patch.
* IKE SPIs may optionally be labeled via the charon.spi_mask|label options in
strongswan.conf. This feature was extracted from charon-tkm, however, now applies the
mask/label in network order.
* The openssl plugin supports ChaCha20-Poly1305 when built with OpenSSL 1.1.0.
* The PB-TNC finite state machine according to section 3.2 of RFC 5793 was not correctly
implemented when sending either a CRETRY or SRETRY batch. These batches can only be sent
in the "Decided" state and a CRETRY batch can immediately carry all messages usually
transported by a CDATA batch. It is currently not possible to send a SRETRY batch since
full-duplex mode for PT-TLS transport is not supported.
* Instead of marking IPv6 virtual IPs as deprecated, the kernel-netlink plugin now uses
address labels to avoid that such addresses are used for non-VPN traffic (00a953d090).
* The agent plugin now creates sockets to the ssh/gpg-agent dynamically and does not keep
them open, which otherwise might prevent the agent from getting terminated.
* To avoid broadcast loops the forecast plugin now only reinjects packets that are marked
or received from the configured interface.
* UTF-8 encoded passwords are supported via EAP-MSCHAPv2, which internally uses an UTF-16LE
encoding to calculate the NT hash (#3014).
* Properly delete temporary drop policies (used when updating IP addresses of SAs) if manual
priorities are used, which was broken since 5.6.2 (8e31d65730).
* Avoid overwriting start_action when parsing the inactivity timeout in the vici plugin (#2954).
* Fixed the automatic termination of reloaded vici connections with start_action=start,
which was broken since 5.6.3 (71b22c250f).
* The lookup for shared secrets for IKEv1 SAs via sql plugin should now work better
(6ec9f68f32).
* Fixed a race condition in the trap manager between installation and removal of a policy
(69cbe2ca3f).
* Compilation of the kernel-netlink plugin has been fixed on old kernels (< 2.6.39), which
was caused by the HW offload changes (c7f579fa17).
* The IPsec stack detection and module loading in starter has been removed (it wasn't
enforced anyway and loading modules doesn't seem necessary, also KLIPS hasn't been
supported for a long time and PF_KEY will eventually be removed from the Linux kernel,
ba817d2917).
* Several IKEv2 protocol details are now handled more strictly: Unrequested virtual IPs are
ignored, CFG_REPLY payloads are ignored if no CFG_REQUEST payloads were sent, a USE
TRANSPORT_MODE notify received from the responder is checked against the local configuration.
* The keys and certificates used by the scenarios in the testing environment are now generated
dynamically. Running the testing/scripts/build-certs script after creating the base and root
images uses the pki utility installed in the latter to create the keys and certificates for
all the CAs and in some cases for individual scenarios. These credentials are stored in the
source tree, not the image, so this has to be called only once even if the images are later
rebuilt. The script automatically (re-)rebuilds the guest images as that generates fresh
CRLs and signs the DNS zones. The only keys/certificates currently not generated are the
very large ones used by the ikev2/rw-eap-tls-fragments scenario.
- Version 5.7.2
===============
* For RSA with PSS padding, the TPM 2.0 specification mandates the maximum salt length
(as defined by the length of the key and hash). However, if the TPM is FIPS-168-4 compliant,
the salt length equals the hash length. This is assumed for FIPS-140-2 compliant TPMs, but
if that's not the case, it might be necessary to manually enable charon.plugins.tpm.fips_186_4
if the TPM doesn't use the maximum salt length.
* Directories for credentials loaded by swanctl are now accessed relative to the loaded
swanctl.conf file, in particular, when loading it from a custom location via --file argument.
* The base directory, which is used if no custom location for swanctl.conf is specified, is now
also configurable at runtime via SWANCTL_DIR environment variable.
* If RADIUS Accounting is enabled, the eap-radius plugin will add the session ID (Acct-Session-Id)
to Access-Request messages, which e.g. simplifies associating database entries for IP leases and
accounting with sessions (the session ID does not change when IKE_SAs are rekeyed, #2853).
* All IP addresses assigned by a RADIUS server are included in Accounting-Stop messages even if
the client did not claim them, allowing to release them early in case of connection errors (#2856).
* Selectors installed on transport mode SAs by the kernel-netlink plugin are now updated if an
IP address changes (e.g. via MOBIKE) and it was part of the selectors.
* No deletes are sent anymore when a rekeyed CHILD_SA expires (#2815).
* The bypass-lan plugin now tracks interfaces to handle subnets that move from one interface
to another and properly update associated routes (#2820).
* Only valid and expected inbound IKEv2 messages are used to update the timestamp of the
last received message (previously, retransmits also triggered an update).
* IKEv2 requests from responders are now ignored until the IKE_SA is fully established (e.g. if a
DPD request from the peer arrives before the IKE_AUTH response does, 46bea1add9).
Delayed IKE_SA_INIT responses with COOKIE notifies we already recevied are ignored, they caused
another reset of the IKE_SA previously (#2837).
* Active and queued Quick Mode tasks are now adopted if the peer reauthenticates an IKEv1 SA
while creating lots of CHILD_SAs.
* Newer versions of the FreeBSD kernel add an SADB_X_EXT_SA2 extension to SADB_ACQUIRE
messages, which allows the kernel-pfkey plugin to determine the reqid of the policy even if it
wasn't installed by the daemon previously (e.g. when using FreeBSD's if_ipsec(4) VTIs, which
install policies themselves, 872b9b3e8d).
* Added support for RSA signatures with SHA-256 and SHA-512 to the agent plugin. For older
versions of ssh/gpg-agent that only support SHA-1, IKEv2 signature authentication has to be
disabled via charon.signature_authentication.
* The sshkey and agent plugins support Ed25519/Ed448 SSH keys and signatures.
* The openssl plugin supports X25519/X448 Diffie-Hellman and Ed25519/Ed448 keys and
signatures when built against OpenSSL 1.1.1.
* Support for Ed25519, ChaCha20/Poly1305, SHA-3 and AES-CCM were added to the botan plugin.
* The mysql plugin now properly handles database connections with transactions
under heavy load (#2779).
* IP addresses in ha pools are now distributed evenly among all segments (#2828).
* Private key implementations may optionally provide a list of supported signature schemes,
which, as described above, is used by the tpm plugin because for each key on a TPM 2.0 the
hash algorithm and for RSA also the padding scheme is predefined.
* The testing environment is now based on Debian 9 (stretch) by default. This required
some changes, in particular, updating to FreeRADIUS 3.x (which forced us to abandon the
TNC@FHH patches and scenarios, 2fbe44bef3) and removing FIPS-enabled versions of
OpenSSL (the FIPS module only supports OpenSSL 1.0.2).
* Most test scenarios were migrated to swanctl.
- Version 5.7.1
===============
* Fixes a vulnerability in the gmp plugin triggered by crafted certificates with RSA keys with
very small moduli. When verifying signatures with such keys, the code patched with the fix
for CVE-2018-16151/2 caused an integer underflow and subsequent heap buffer overflow
that results in a crash of the daemon.
* The vulnerability has been registered as CVE-2018-17540.
- Version 5.7.0
===============
* Fixes a potential authorization bypass vulnerability in the gmp plugin that was caused by a
too lenient verification of PKCS#1 v1.5 signatures. Several flaws could be exploited by a
Bleichenbacher-style attack to forge signatures for low-exponent keys (i.e. with e=3).
* CVE-2018-16151 has been assigned to the problem of accepting random bytes after the OID
of the hash function in such signatures, and CVE-2018-16152 has been assigned to the issue
of not verifying that the parameters in the ASN.1 algorithmIdentitifer structure is empty.
Other flaws that don't lead to a vulnerability directly (e.g. not checking for at least
8 bytes of padding) have no separate CVE assigned.
* Dots are not allowed anymore in section names in swanctl.conf and strongswan.conf.
This mainly affects the configuration of file loggers. If the path for such a log file
contains dots it now has to be configured in the new path setting within the arbitrarily
renamed subsection in the filelog section.
* Sections in swanctl.conf and strongswan.conf may now reference other sections. All settings
and subsections from such a section are inherited. This allows to simplify configs as
redundant information has only to be specified once and may then be included in other
sections (see strongswan.conf for an example).
* The originally selected IKE config (based on the IPs and IKE version) can now change
if no matching algorithm proposal is found. This way the order of the configs doesn't
matter that much anymore and it's easily possible to specify separate configs for
clients that require weaker algorithms (instead of having to also add them in other
configs that might be selected).
* Support for Postquantum Preshared Keys for IKEv2 (draft-ietf-ipsecme-qr-ikev2) has been added.
For an example refer to the swanctl/rw-cert-ppk scenario (or with EAP, or PSK authentication).
* The new botan plugin is a wrapper around the Botan C++ crypto library.
It requires a fairly recent build from Botan's master branch (or the upcoming 2.8.0 release).
Thanks to René Korthaus and his team from Rohde & Schwarz Cybersecurity for the initial
patch and to Jack Lloyd for quickly adding missing functions to Botan's FFI (C89) interface.
* Implementation of RFC 8412 "Software Inventory Message and Attributes (SWIMA) for PA-TNC".
* SWIMA subscription option sets CLOSE_WRITE trigger on apt history.log file resulting in
a ClientRetry PB-TNC batch to initialize a new measurement cycle. The new imv/imc-swima
plugins replace the previous imv/imc-swid plugins, which were removed.
* Added support for fuzzing the PA-TNC (RFC 5792) and PB-TNC (RFC 5793) NEA protocols
on Google's OSS-Fuzz infrastructure.
* Support for version 2 of Intel's TPM2-TSS TGC Software Stack. The presence of the
in-kernel /dev/tpmrm0 resource manager is automatically detected.
* The pki tool accepts a xmppAddr otherName as a subjectAlternativeName using the
syntax --san xmppaddr:<jid>.
* swanctl.conf supports the configuration of marks the in- and/or outbound SA should apply
to packets after processing on Linux. Configuring such a mark for outbound SAs requires
at least a 4.14 kernel. The ability to set a mask and configuring a mark/mask for
inbound SAs will be added with the upcoming 4.19 kernel.
* New options in swanctl.conf allow configuring how/whether DF, ECN and DS fields in the
IP headers are copied during IPsec processing. Controlling this is currently only possible
on Linux.
* The handling of sequence numbers in IKEv1 DPDs has been improved (#2714).
* To avoid conflicts, the dhcp plugin now only uses the DHCP server port if explicitly
configured.
- Version 5.6.3
===============
* 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.
* 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.
* 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 cases.
* In compliance with RFC 4945, section 5.1.3.2, 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 directories.
* 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).
Notes for developers:
* trap_manager_t: Trap policies are now unistalled by peer/child name and not the reqid.
* No reqid is returned anymore when installing trap policies.
* child_sa_t: A new state (CHILD_DELETED) is used for CHILD_SAs that have been deleted but
not yet destroyed (after a rekeying CHILD_SAs are kept around for a while to process
delayed packets).
This way child_updown events are not triggered anymore for such SAs when an IKE_SA that
has such CHILD_SAs assigned is deleted.
- 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 peer.
* 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 2.0.
* 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 PCR.
* 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.
- Version 5.6.1
===============
* Several algorithms were removed from the default ESP/AH and IKE proposals in compliance with
RFC 8221 and RFC 8247, respectively. Removed from the default ESP/AH proposal were the
3DES and Blowfish encryption algorithms and the HMAC-MD5 integrity algorithm. From the IKE
default proposal the HMAC-MD5 integrity algorithm and the MODP-1024 Diffie-Hellman group
were removed (the latter is significant for Windows clients in their default configuration).
These algorithms may still be used in custom proposals.
* Support for RSASSA-PSS signatures has been added. For compatibility with previous
releases they are currently not used automatically, by default, to change that charon.rsa_pss
may be enabled. To explicitly use or require such signatures during IKEv2 signature
authentication (RFC 7427) ike:rsa/pss... authentication constraints may be used for specific
connections (regardless of whether the strongswan.conf option above is enabled). Only the
hash algorithm can be specified in such constraints, the MGF1 will be based on that hash
and the salt length will equal the hash length (when verifying the salt length is not
enforced).
To enforce such signatures during PKI verification use rsa/pss... authentication constraints.
* All pki commands that create certificates/CRLs can be made to sign with RSASSA-PSS instead
of the classing PKCS#1 scheme with the --rsa-padding pss option. As with signatures during
authentication, only the hash algorithm is configurable (via --digest option), the MGF1 will
be based on that and the salt length will equal the hash length.
* These signatures are supported by all RSA backends except pkcs11 (i.e. gmp, gcrypt, openssl).
The gmp plugin requires the mgf1 plugin.
Note that RSASSA-PSS algorithm identifiers and parameters in keys (public keys in
certificates or private keys in PKCS#8 files) are currently not used as constraints.
* The sec-updater tool checks for security updates in dpkg-based repositories
(e.g. Debian/Ubuntu) and sets the security flags in the IMV policy database accordingly.
Additionally for each new package version a SWID tag for the given OS and HW architecture
is created and stored in the database.
* Using the sec-updater.sh script template the lookup can be automated (e.g. via an hourly
cron job).
* When restarting an IKEv2 negotiation after receiving an INVALID_KE_PAYLOAD notify (or due
to other reasons like too many retransmits) a new initiator SPI is allocated. This
prevents issues caused by retransmits for IKE_SA_INIT messages.
* Because the initiator SPI was previously reused when restarting the connection delayed
responses for previous connection attempts were processed and might have caused fatal
errors due to a failed DH negotiation or because of the internal retry counter in the
ike-init task. For instance, if we proposed a DH group the responder rejected we
might have later received delayed responses that either contained INVALID_KE_PAYLOAD
notifies with the DH group we already switched to, or, if we retransmitted an
IKE_SA_INIT with the requested group but then had to restart again, a KE payload with
a group different from the one we proposed.
* The introduction of file versions in the IMV database scheme broke file reference hash
measurements. This has been fixed by creating generic product versions having an empty
package name.
* A new timeout option for the systime-fix plugin stops periodic system time checks after
a while and enforces a certificate verification, closing or reauthenticating all SAs
with invalid certificates.
* The IKE event counters, previously only available via ipsec listcounters command, may
now also be queried and reset via vici and the new swanctl --counters command. They
are collected and provided by the optional counters plugin (enabled by default for
backwards compatibility if the stroke plugin is built).
* Class attributes received in RADIUS Access-Accept messages may optionally be added to
RADIUS accounting messages (655924074b).
* Basic support for systemd sockets has been added, which may be used for privilege separation
(59db98fb94).
* Inbound marks may optionally be installed in the SA again (was removed with 5.5.2) by
enabling the mark_in_sa option in swanctl.conf.
* The timeout of leases in pools configured via pool utility may be configured in other
units than hours.
INITIAL_CONTACT notifies are now only omitted if never is configured as uniqueness policy.
* Outbound FWD policies for shunts are not installed anymore, by default (as is the case
for other policies since 5.5.1).
* Don't consider a DH group mismatch during CHILD_SA rekeying as failure as responder
(e7276f78aa).
* Handling of fragmented IPv4 and IPv6 packets in libipsec has been improved (e138003de9).
* Trigger expire events for the correct IPsec SA in libipsec (6e861947a0).
* A crash in CRL verification via openssl plugin using OpenSSL 1.1 has been fixed (78acaba6a1).
* No hard-coded default proposals are passed from starter to the stroke plugin anymore (the
IKE proposal used curve25519 since 5.5.2, which is an optional plugin).
* A workaround for an issue with virtual IPs on macOS 10.13 (High Sierra) has been added
(039b85dd43).
* Handling of IKE_SA rekey collisions in charon-tkm has been fixed.
* Instead of failing or just silently doing nothing unit tests may now warn about certain
conditions (e.g. if a test was not executed due to external dependencies).

- 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).

-------------------------------------------------------------------
Mon Jul 31 18:30:28 CEST 2017 - ndas@suse.de
- 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 4 12:00:00 UTC 2016 - doug@uq.edu.au
- 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
implementation.
* 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
segmented.
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
CVE-2015-3991.
* The new aesni plugin provides CBC, CTR, XCBC, CMAC, CCM and
GCM crypto primitives for AES-128/192/256. The plugin requires
AES-NI and PCLMULQDQ instructions and works on both x86 and
x64 architectures. It provides superior crypto performance in
userland without any external libraries.
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 5 14:38:46 UTC 2015 - mt@suse.de
- 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 (https://github.com/strongswan/swidGenerator) which
generates SWID tags according to the new ISO/IEC 19770-2:2014 standard.
* All IMVs now share the access requestor ID, device ID and product info
of an access requestor via a common imv_session object.
* The Attestation IMC/IMV pair supports the IMA-NG measurement format
introduced with the Linux 3.13 kernel.
* The aikgen tool generates an Attestation Identity Key bound to a TPM.
* Implemented the PT-EAP transport protocol (RFC 7171) for Trusted Network
Connect.
* The ipsec.conf replay_window option defines connection specific IPsec
replay windows. Original patch courtesy of Zheng Zhong and Christophe
Gouault from 6Wind.

- Applied an upstream fix for a denial-of-service vulnerability,
which can be triggered by an IKEv2 Key Exchange payload, that
contains the Diffie-Hellman group 1025 (bsc#910491,CVE-2014-9221).
[+ 0006-strongswan-5.1.2-5.2.1_modp_custom.CVE-2014-9221.patch]
- Adjusted whilelist of approved algorithms in fips mode (bsc#856322).
[* strongswan_fipsfilter.patch]
- Renamed patch file to match it's patch number:
[- 0001-restore-registration-algorithm-order.bug897512.patch,

-------------------------------------------------------------------
Tue Nov 25 11:22:06 UTC 2014 - mt@suse.de
- Updated strongswan-hmac package description (bsc#856322).
-------------------------------------------------------------------
Fri Nov 21 12:03:59 UTC 2014 - mt@suse.de
- Disabled explicit gpg validation; osc source_validator does it.
- Guarded fipscheck and hmac package in the spec file for >13.1.
-------------------------------------------------------------------
Thu Nov 20 07:43:43 UTC 2014 - mt@suse.de
- Added generation of fips hmac hash files using fipshmac utility
and a _fipscheck script to verify binaries/libraries/plugings
shipped in the strongswan-hmac package.
With enabled fips in the kernel, the ipsec script will call it
before any action or in a enforced/manual "ipsec _fipscheck" call.
Added config file to load openssl and kernel af-alg plugins, but
not all the other modules which provide further/alternative algs.
Applied a filter disallowing non-approved algorithms in fips mode.
(fate#316931,bnc#856322).
[+ strongswan_fipscheck.patch, strongswan_fipsfilter.patch]
- Fixed file list in the optional (disabled) strongswan-test package.
- Fixed build of the strongswan built-in integrity checksum library
and enabled building it only on architectures tested to work.
- Fix to use bug number 897048 instead 856322 in last changes entry.
- Applied an upstream patch reverting to store algorithms in the
registration order again as ordering them by identifier caused
weaker algorithms to be proposed first by default (bsc#897512).
[+0001-restore-registration-algorithm-order.bug897512.patch]
-------------------------------------------------------------------
Fri Sep 26 16:02:09 UTC 2014 - mt@suse.de
- Re-enabled gcrypt plugin and reverted to not enforce fips again
as this breaks gcrypt and openssl plugins when the fips pattern
option is not installed (fate#316931,bnc#856322).
[- strongswan-fips-disablegcrypt.patch]
- Added empty strongswan-hmac package supposed to provide fips hmac
files and enforce fips compliant operation later (bnc#856322).
- Cleaned up conditional build flags in the rpm spec file.
-------------------------------------------------------------------
Thu Jul 3 13:39:45 UTC 2014 - meissner@suse.com
- disable gcrypt plugin by default, so it will only use openssl
fate#316931 [+strongswan-fips-disablegcrypt.patch]
- enable fips mode 2
-------------------------------------------------------------------
Fri Jun 20 17:38:07 UTC 2014 - crrodriguez@opensuse.org
- Fix build in factory
* Do not include var/run directories in package
* Move runtime data to /run and provide tmpfiles.d snippet
* Add proper systemd macros to rpm scriptlets.
* Do not buildRequire library package libnl1, it is not used.
-------------------------------------------------------------------
Mon Apr 14 23:36:07 UTC 2014 - mt@suse.de
- 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
different
-------------------------------------------------------------------
Wed Apr 2 05:53:21 UTC 2014 - mt@suse.de
- 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 1 12:28:39 UTC 2013 - mt@suse.de
- 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
packets.
- With two new strongswan.conf options fwmarks can be used to implement
host-to-host tunnels with kernel-libipsec.
- load-tester supports transport mode connections and more complex
traffic selectors, including such using unique ports for each tunnel.
- The new dnscert plugin provides support for authentication via CERT
RRs that are protected via DNSSEC. The plugin was created by Ruslan
N. Marchenko.
- The eap-radius plugin supports forwarding of several Cisco Unity
specific RADIUS attributes in corresponding configuration payloads.
- Database transactions are now abstracted and implemented by the two
backends. If you use MySQL make sure all tables use the InnoDB engine.
- libstrongswan now can provide an experimental custom implementation
of the printf family functions based on klibc if neither Vstr nor
glibc style printf hooks are available. This can avoid the Vstr
dependency on some systems at the cost of slower and less complete
printf functions.
- Adjusted file lists: this version installs the pki utility and manuals
in common /usr directories and additional ipsec/pt-tls-client helper.
-------------------------------------------------------------------
Mon Aug 5 13:48:11 UTC 2013 - mt@suse.de
- 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
CVE-2013-5018.
- The new charon-cmd command line IKE client can establish road
warrior connections using IKEv1 or IKEv2 with different
authentication profiles. It does not depend on any configuration
files and can be configured using a few simple command line options.
- The kernel-pfroute networking backend has been greatly improved.
It now can install virtual IPs on TUN devices on OS X and FreeBSD,
allowing these systems to act as a client in common road warrior
scenarios.
- The new kernel-libipsec plugin uses TUN devices and libipsec to
provide IPsec processing in userland on Linux, FreeBSD and Mac OS X.
- The eap-radius plugin can now serve as an XAuth backend called
xauth-radius, directly verifying XAuth credentials using RADIUS
User-Name/User-Password attributes. This is more efficient than the
existing xauth-eap+eap-radius combination, and allows RADIUS servers
without EAP support to act as AAA backend for IKEv1.
- The new osx-attr plugin installs configuration attributes (currently
DNS servers) via SystemConfiguration on Mac OS X. The keychain
plugin provides certificates from the OS X keychain service.
- The sshkey plugin parses SSH public keys, which, together with the
--agent option for charon-cmd, allows the use of ssh-agent for
authentication. To configure SSH keys in ipsec.conf the
left|rightrsasigkey options are replaced with left|rightsigkey,
which now take public keys in one of three formats: SSH (RFC 4253,
ssh: prefix), DNSKEY (RFC 3110, dns: prefix), and PKCS#1 (the
default, no prefix).
- Extraction of certificates and private keys from PKCS#12 files is
now provided by the new pkcs12 plugin or the openssl plugin.
charon-cmd (--p12) as well as charon (via P12 token in
ipsec.secrets) can make use of this.
- IKEv2 can now negotiate transport mode and IPComp in NAT situations.
- IKEv2 exchange initiators now properly close an established IKE or
CHILD_SA on error conditions using an additional exchange, keeping
state in sync between peers.
- Using a SQL database interface a Trusted Network Connect (TNC)
Policy Manager can generate specific measurement workitems for an
arbitrary number of Integrity Measurement Verifiers (IMVs) based on
the history of the VPN user and/or device.
- Several core classes in libstrongswan are now tested with unit
tests. These can be enabled with --enable-unit-tests and run with
'make check'.
Coverage reports can be generated with --enable-coverage and 'make
coverage' (this disables any optimization, so it should not be
enabled when building production releases).
- The leak-detective developer tool has been greatly improved. It
works much faster/stabler with multiple threads, does not use
deprecated malloc hooks anymore and has been ported to OS X.
- chunk_hash() is now based on SipHash-2-4 with a random key. This
provides better distribution and prevents hash flooding attacks
when used with hashtables.
- All default plugins implement the get_features() method to define
features and their dependencies. The plugin loader has been
improved, so that plugins in a custom load statement can be ordered
freely or to express preferences without being affected by
dependencies between plugin features.
- A centralized thread can take care for watching multiple file
descriptors concurrently. This removes the need for a dedicated
listener threads in various plugins. The number of "reserved"
threads for such tasks has been reduced to about five, depending on
the plugin configuration.
- Plugins that can be controlled by a UNIX socket IPC mechanism gained
network transparency. Third party applications querying these
plugins now can use TCP connections from a different host.
- libipsec now supports AES-GCM.
-------------------------------------------------------------------
Tue Apr 30 12:48:44 UTC 2013 - mt@suse.de
- 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.
See http://wiki.strongswan.org/projects/strongswan/wiki/Changelog50
for a list of all changes since the 5.0.1 release.
-------------------------------------------------------------------
Thu Nov 29 19:13:40 CET 2012 - sbrabec@suse.cz
- Verify GPG signature.

- Fix systemd unit dir
-------------------------------------------------------------------
Wed Oct 31 15:25:16 UTC 2012 - mt@suse.de
- 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
charon.install_virtual_ip_on.
- 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
part.
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:
http://wiki.strongswan.org/projects/strongswan/wiki/Changelog50
- 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 7 08:36:57 UTC 2012 - mt@suse.de
- 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 http://wiki.strongswan.org/issues/198 for more informations.
-------------------------------------------------------------------
Thu May 31 16:08:43 UTC 2012 - mt@suse.com
- 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 09:15:38 UTC 2012 - mt@suse.com
- 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 3 00:10:34 UTC 2012 - tabraham@novell.com
- 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 13:31:40 UTC 2012 - mt@suse.com
- 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
dynamiclibraries.
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 6 10:27:00 UTC 2012 - aj@suse.de
- Only glib.h can be included, fix compilation.

-------------------------------------------------------------------
Thu Sep 8 16:06:46 UTC 2011 - mt@suse.com
- 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
directory.
* The dynamic IMC/IMV libraries were moved from the plugins directory to
a new imcvs directory in the prefix/lib/ipsec/ subdirectory.
* Job priorities were introduced to prevent thread starvation caused by too
many threads handling blocking operations (such as CRL fetching).
* 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
interfaces.
* The history of policies installed in the kernel is now tracked so that e.g.
trap policies are correctly updated when reauthenticated SAs are terminated.
* IMC/IMV Scanner pair implementing the RFC 5792 PA-TNC (IF-M) protocol.
Using "netstat -l" the IMC scans open listening ports on the TNC client
and sends a port list to the IMV which based on a port policy decides if
the client is admitted to the network.
* 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 16:37:00 UTC 2011 - jcnengel@googlemail.com
- 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.
esp=aes128-sha1-esn-noesn.
* In addition to ESN, Linux 2.6.39 gained support for replay windows larger
than 32 packets. The new global strongswan.conf option 'charon.replay_window'
configures the size of the replay window, in packets.

-------------------------------------------------------------------
Mon Nov 22 09:05:30 UTC 2010 - mt@suse.de
- 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 12:01:46 UTC 2010 - mt@suse.de
- 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 11:43:38 UTC 2010 - mt@suse.de
- 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 2 15:40:17 UTC 2010 - mt@suse.de
- 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 2 14:16:18 UTC 2010 - mt@suse.de
- Added README.SUSE to source list in the spec file.
-------------------------------------------------------------------
Fri May 14 19:19:04 UTC 2010 - mt@suse.de
- 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
http://wiki.strongswan.org/projects/strongswan/wiki/HighAvailability.
The development of the High Availability functionality was sponsored
by secunet Security Networks AG.
* Added IKEv1 and IKEv2 configuration support for the AES-GMAC
authentication-only ESP cipher. Our aes_gmac kernel patch or a Linux
2.6.34 kernel is required to make AES-GMAC available via the XFRM
kernel interface.
* Added support for Diffie-Hellman groups 22, 23 and 24 to the gmp,
gcrypt and openssl plugins, usable by both pluto and charon. The new
proposal keywords are modp1024s160, modp2048s224 and modp2048s256.
Thanks to Joy Latten from IBM for 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 2 21:42:10 CET 2010 - mt@suse.de
- 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
constraints.
* The new ipsec.conf conn option "inactivity" closes a CHILD_SA if
no traffic was sent or received within the given interval. To close
the complete IKE_SA if its only CHILD_SA was inactive, set the
global strongswan.conf option "charon.inactivity_close_ike" to yes.
* More detailed IKEv2 EAP payload information in debug output
* IKEv2 EAP-SIM and EAP-AKA share joint libsimaka library
* Added required userland changes for proper SHA256 and SHA384/512
in ESP that will be introduced with Linux 2.6.33.
The "sha256"/"sha2_256" keyword now configures the kernel with 128
bit truncation, not the non-standard 96 bit truncation used by
previous releases. To use the old 96 bit truncation scheme, the new
"sha256_96" proposal keyword has been introduced.
* Fixed IPComp in tunnel mode, stripping out the duplicated outer
header. This change makes IPcomp tunnel mode connections
incompatible with previous releases; disable compression on such
tunnels.
* Fixed BEET mode connections on recent kernels by installing SAs
with appropriate traffic selectors, based on a patch by Michael
Rossberg.
* Using extensions (such as BEET mode) and crypto algorithms (such
as twofish, serpent, sha256_96) allocated in the private use space
now require that we know its meaning, i.e. we are talking to
strongSwan. Use the new "charon.send_vendor_id" option in
strongswan.conf to let the remote peer know this is the case.
* Experimental support for draft-eronen-ipsec-ikev2-eap-auth, where
the responder omits public key authentication in favor of a mutual
authentication method. To enable EAP-only authentication, set
rightauth=eap on the responder to rely only on the MSK constructed
AUTH payload. This not-yet standardized extension requires the
strongSwan vendor ID introduced above.
* The IKEv1 daemon ignores the Juniper SRX notification type 40001,
thus allowing interoperability.
* 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 4 12:56:59 CEST 2009 - mt@suse.de
- Fixed open failure debug message in load_secrets
-------------------------------------------------------------------
Thu Sep 3 23:44:37 CEST 2009 - mt@suse.de
- Applied patch fixing locking in ipsec.secrets inclusion.
-------------------------------------------------------------------
Mon Aug 31 16:06:13 CEST 2009 - mt@suse.de
- Updated to strongSwan 4.3.4 release:
* IKEv2 charon daemon ported to FreeBSD and Mac OS X. Installation
details can be found on wiki.strongswan.org.
* ipsec statusall shows the number of bytes transmitted and received
over ESP connections configured by the IKEv2 charon daemon.
* The IKEv2 charon daemon supports include files in ipsec.secrets.
- Removed obsolete ipsec.secrets include patch (bnc#524799)
and patch to avoid libchecksum version.
-------------------------------------------------------------------
Fri Aug 7 11:44:30 CEST 2009 - mt@suse.de
- Applied patch implementing ipsec.secrets "include" directive
support in charon (http://wiki.strongswan.org/issues/show/82,
bnc#524799).
-------------------------------------------------------------------
Mon Jul 27 13:40:57 CEST 2009 - mt@suse.de
- 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 11:04:44 CEST 2009 - mt@suse.de
- 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.

- 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
