+strongswan-5.7.2
+----------------
+
+- Private key implementations may optionally provide a list of supported
+ signature schemes, which 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.
+
+- 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.
+
+- swanctl now accesses directories for credentials relative to swanctl.conf, in
+ particular, when it's loaded from a custom location via --file argument. The
+ base directory that's used if --file is not given is configurable at runtime
+ via SWANCTL_DIR environment variable.
+
+- With RADIUS Accounting enabled, the eap-radius plugin adds the session ID to
+ Access-Request messages, simplifying associating database entries for IP
+ leases and accounting with sessions.
+
+- IPs assigned by RADIUS servers are included in Accounting-Stop even if clients
+ don't claim them, allowing releasing them early on connection errors.
+
+- Selectors installed on transport mode SAs by the kernel-netlink plugin are
+ updated on IP address changes (e.g. via MOBIKE).
+
+- 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.
+
+- 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.
+
+- IP addresses in HA pools are now distributed evenly among all segments.
+
+- On newer FreeBSD kernels, the kernel-pfkey plugin reads the reqid directly
+ from SADB_ACQUIRE messages, i.e. not requiring previous policy installation by
+ the plugin, e.g. for compatibility with if_ipsec(4) VTIs.
+
+
+strongswan-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.
+
+
+strongswan-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 (refer to the example in the man
+ page for strongswan.conf).
+
+- 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 weak 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.
+
+- 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.
+
+- The pki tool accepts a xmppAddr otherName as a subjectAlternativeName using
+ the syntax --san xmppaddr:<jid>.
+
+- 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.
+
+- 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.
+
+- Marks the in- and/or outbound SA should apply to packets after processing may
+ be configured in swanctl.conf on Linux. For outbound SAs this requires at
+ least a 4.14 kernel. Setting 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.
+
+- To avoid conflicts, the dhcp plugin now only uses the DHCP server port if
+ explicitly configured.
+
+
+strongswan-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 CRLs and the clock on the host
+ doing the revocation check is trailing behind that of the host issuing CRLs.
+
+- The issuer of fetched CRLs is now compared to the issuer of the checked
+ certificate.
+
+- 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 before destroying the IKE_SA is also possible
+ by additionally specifying a timeout.
+
+- 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.
+
+- The dhcp plugin only sends the client identifier option if identity_lease is
+ enabled. It can also send identities of up to 255 bytes length, instead of
+ the previous 64 bytes. If a server address is configured, DHCP requests are
+ now sent from port 67 instead of 68 to avoid ICMP port unreachables.
+
+- Roam events are now completely ignored for IKEv1 SAs.
+
+- ChaCha20/Poly1305 is now correctly proposed without key length. For
+ compatibility with older releases the chacha20poly1305compat keyword may be
+ included in proposals to also propose the algorithm with a key length.
+
+- Configuration of hardware offload of IPsec SAs is now more flexible and allows
+ a new mode, which automatically uses it if the kernel and device support it.
+
+- SHA-2 based PRFs are supported in PKCS#8 files as generated by OpenSSL 1.1.
+
+- The pki --verify tool may load CA certificates and CRLs from directories.
+
+- Fixed an issue with DNS servers passed to NetworkManager in charon-nm.
+
+
+strongswan-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.
+
+- The previously negotiated DH group is reused when rekeying an SA, instead of
+ using the first group in the configured proposals, which avoids an additional
+ exchange if the peer selected a different group via INVALID_KE_PAYLOAD when
+ the SA was created initially.
+ The selected DH group is also moved to the front of 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 is not ignored anymore if only an address list update or
+ DPD is queued.
+
+- 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.
+
+- 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
+ proposals during IKE_AUTH and also if a DH group is configured in the local
+ ESP proposal and charon.prefer_configured_proposals is disabled.
+
+- 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).
+
+- 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.
+
+
+strongswan-5.6.1
+----------------
+
+- In compliance with RFCs 8221 and 8247 several algorithms were removed from the
+ default ESP/AH and IKEv2 proposals, respectively (3DES, Blowfish and MD5 from
+ ESP/AH, MD5 and MODP-1024 from IKEv2). These algorithms may still be used in
+ custom proposals.
+
+- Added support for RSASSA-PSS signatures. For backwards compatibility they are
+ not used automatically by default, enable charon.rsa_pss to change that. To
+ explicitly use or require such signatures with IKEv2 signature authentication
+ (RFC 7427), regardless of whether that option is enabled, use ike:rsa/pss...
+ authentication constraints.
+
+- The pki tool can optionally sign certificates/CRLs with RSASSA-PSS via the
+ `--rsa-padding pss` option.
+
+- 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).
+
+- 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, may
+ now be queried/reset via vici and the new swanctl --counters command. They are
+ provided by the new optional counters plugin.
+
+- Class attributes received in RADIUS Access-Accept messages may optionally be
+ added to RADIUS accounting messages.
+
+- Inbound marks may optionally be installed on the SA again (was removed with
+ 5.5.2) by enabling the mark_in_sa option in swanctl.conf.
+
+
+strongswan-5.6.0
+----------------
+
+- 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.
+
+- 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 sw-collector tool extracts software events from apt history logs
+ and stores them in an SQLite database to be used by the SWIMA IMC.
+ The tool can also generate SWID tags both for installed and removed
+ package versions.
+
+- The pt-tls-client can attach and use TPM 2.0 protected private keys
+ via the --keyid parameter.
+
+- libtpmtss supports Intel's TSS2 Architecture Broker and Resource
+ Manager interface (tcti-tabrmd).
+
+- The new eap-aka-3gpp plugin implements the 3GPP MILENAGE algorithms
+ in software. K (optionally concatenated with OPc) may be configured as
+ binary EAP secret.
+
+- CHILD_SA rekeying was fixed in charon-tkm and was slightly changed: The
+ switch to the new outbound IPsec SA now happens via SPI on the outbound
+ policy on Linux, and in case of lost rekey collisions no outbound SA/policy
+ is temporarily installed for the redundant CHILD_SA.
+
+- The new %unique-dir value for mark* settings allocates separate unique marks
+ for each CHILD_SA direction (in/out).
+
+
+strongswan-5.5.3
+----------------
+
+- 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.
+
+- 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.
+
+- The behavior during IKEv2 CHILD_SA rekeying has been changed in order to avoid
+ traffic loss. 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. Similarly, 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 to reduce the chance of dropping delayed packets.
+
+- The code base has been ported to Apple's ARM64 iOS platform, whose calling
+ conventions for variadic and regular functions are different. This means
+ assigning non-variadic functions to variadic function pointers does not work.
+ To avoid this issue the enumerator_t interface has been changed and the
+ signatures of the callback functions for enumerator_create_filter(), and the
+ invoke_function() and find_first() methods on linked_list_t have been changed.
+ The return type of find_first() also changed from status_t to bool.
+
+- Added support for fuzzing the certificate parser provided by the default
+ plugins (x509, pem, gmp etc.) on Google's OSS-Fuzz infrastructure. 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.
+
+- 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).
+
+- Added support for hardware offload of IPsec SAs as introduced by Linux 4.11
+ for hardware that supports this.
+
+- When building the libraries monolithically and statically the plugin
+ constructors are now hard-coded in each library so the plugin code is not
+ removed by the linker because it thinks none of their symbols are ever
+ referenced.
+
+- The pki tool loads the curve25519 plugin by default.
+
+
+strongswan-5.5.2
+----------------
+
+- Support of Diffie-Hellman group 31 using Curve25519 for IKE as defined
+ by RFC 8031.
+
+- Support of Ed25519 digital signature algorithm for IKEv2 as defined by
+ draft-ietf-ipsecme-eddsa. Ed25519-based public key pairs, X.509 certificates
+ and CRLs can be generated and printed by the pki tool.
+
+- The new "tpm" libtpmtss plugin allows to use persistent private RSA and ECDSA
+ keys bound to a TPM 2.0 for both IKE and TLS authentication. Using the
+ TPM 2.0 object handle as keyid parameter, the pki --pub tool can extract
+ the public key from the TPM thereby replacing the aikpub2 tool. In a similar
+ fashion pki --req can generate a PKCS#10 certificate request signed with
+ the TPM private key.
+
+- The pki tool gained support for generating certificates with the RFC 3779
+ addrblock extension. The charon addrblock plugin now dynamically narrows
+ traffic selectors based on the certificate addrblocks instead of rejecting
+ non-matching selectors completely. This allows generic connections, where
+ the allowed selectors are defined by the used certificates only.
+
+- In-place update of cached base and delta CRLs does not leave dozens
+ of stale copies in cache memory.
+
+- Several new features for the VICI interface and the swanctl utility: Querying
+ specific pools, enumerating and unloading keys and shared secrets, loading
+ keys and certificates from PKCS#11 tokens, the ability to initiate, install
+ and uninstall connections and policies by their exact name (if multiple child
+ sections in different connections share the same name), a command to initiate
+ the rekeying of IKE and IPsec SAs, support for settings previously only
+ supported by the old config files (plain pubkeys, dscp, certificate policies,
+ IPv6 Transport Proxy Mode, NT Hash secrets, mediation extension).
+
+ Important: Due to issues with VICI bindings that map sub-sections to
+ dictionaries the CHILD_SA sections returned via list-sas now have a unique
+ name, the original name of a CHILD_SA is returned in the "name" key of its
+ section.
+
+
+strongswan-5.5.1
+----------------
+
+- The newhope plugin implements the post-quantum NewHope key exchange algorithm
+ proposed in their 2015 paper by Erdem Alkim, Léo Ducas, Thomas Pöppelmann and
+ Peter Schwabe.
+
+- The libstrongswan crypto factory now offers the registration of Extended
+ Output Functions (XOFs). Currently supported XOFs are SHAKE128 and SHAKE256
+ implemented by the sha3 plugin, ChaCHa20 implemented by the chapoly plugin
+ and the more traditional MGF1 Mask Generation Functions based on the SHA-1,
+ SHA-256 and SHA-512 hash algorithms implemented by the new mgf1 plugin.
+
+- The pki tool, with help of the pkcs1 or openssl plugins, can parse private
+ keys in any of the supported formats without having to know the exact type.
+ So instead of having to specify rsa or ecdsa explicitly the keyword priv may
+ be used to indicate a private key of any type. Similarly, swanctl can load
+ any type of private key from the swanctl/private directory.
+
+- The pki tool can handle RSASSA-PKCS1v1.5-with-SHA-3 signatures using the
+ sha3 and gmp plugins.
+
+- The VICI flush-certs command flushes certificates from the volatile
+ certificate cache. Optionally the type of the certificates to be
+ flushed (e.g. type = x509_crl) can be specified.
+
+- Setting cache_crls = yes in strongswan.conf the vici plugin saves regular,
+ base and delta CRLs to disk.
+
+- IKE fragmentation is now enabled by default with the default fragment size
+ set to 1280 bytes for both IP address families.
+
+- libtpmtss: In the TSS2 API the function TeardownSocketTcti() was replaced by
+ tss2_tcti_finalize().
+
+
+strongswan-5.5.0
+----------------
+
+- The new libtpmtss library offers support for both TPM 1.2 and TPM 2.0
+ Trusted Platform Modules. This allows the Attestation IMC/IMV pair to
+ do TPM 2.0 based attestation.
+
+- The behavior during IKEv2 exchange collisions has been improved/fixed in
+ several corner cases and support for TEMPORARY_FAILURE and CHILD_SA_NOT_FOUND
+ notifies, as defined by RFC 7296, has been added.
+
+- IPsec policy priorities can be set manually (e.g. for high-priority drop
+ policies) and outbound policies may be restricted to a network interface.
+
+- The scheme for the automatically calculated default priorities has been
+ changed and now also considers port masks, which were added with 5.4.0.
+
+- FWD policies are now installed in both directions in regards to the traffic
+ selectors. Because such "outbound" FWD policies could conflict with "inbound"
+ FWD policies of other SAs they are installed with a lower priority and don't
+ have a reqid set, which allows kernel plugins to distinguish between the two
+ and prefer those with a reqid.
+
+- For outbound IPsec SAs no replay window is configured anymore.
+
+- Enhanced the functionality of the swanctl --list-conns command by listing
+ IKE_SA and CHILD_SA reauthentication and rekeying settings, and EAP/XAuth
+ identities and EAP types.
+
+- DNS servers installed by the resolve plugin are now refcounted, which should
+ fix its use with make-before-break reauthentication. Any output written to
+ stderr/stdout by resolvconf is now logged.
+
+- The methods in the kernel interfaces have been changed to take structs instead
+ of long lists of arguments. Similarly the constructors for peer_cfg_t and
+ child_cfg_t now take structs.

The debugging levels can either be specified statically in ipsec.conf as
config setup
- charondebug="lib 1, cfg 3, net 2"
+ charondebug="lib 1, cfg 3, net 2"
or changed at runtime via stroke as
if an FQDN, USER_FQDN, or Key ID was defined, as in the following example.
conn rw
- right=%any
- rightid=@foo.bar
- authby=secret
+ right=%any
+ rightid=@foo.bar
+ authby=secret
- the ipsec command now supports most ipsec auto commands (e.g. ipsec listall).
strongswan-2.5.7
----------------
-- CA certicates are now automatically loaded from a smartcard
+- CA certificates are now automatically loaded from a smartcard
or USB crypto token and appear in the ipsec auto --listcacerts
listing.
- fixed the initialization of the ESP key length to a default of
128 bits in the case that the peer does not send a key length
- attribute for AES encryption.
+ attribute for AES encryption.
- applied Herbert Xu's uniqueIDs patch
- Under the native IPsec of the Linux 2.6 kernel, a %trap eroute
installed either by setting auto=route in ipsec.conf or by
a connection put into hold, generates an XFRM_AQUIRE event
- for each packet that wants to use the not-yet exisiting
+ for each packet that wants to use the not-yet existing
tunnel. Up to now each XFRM_AQUIRE event led to an entry in
the Quick Mode queue, causing multiple IPsec SA to be
established in rapid succession. Starting with strongswan-2.5.1
- The new "ca" section allows to define the following parameters:
ca kool
- cacert=koolCA.pem # cacert of kool CA
- ocspuri=http://ocsp.kool.net:8001 # ocsp server
- ldapserver=ldap.kool.net # default ldap server
- crluri=http://www.kool.net/kool.crl # crl distribution point
- crluri2="ldap:///O=Kool, C= .." # crl distribution point #2
- auto=add # add, ignore
+ cacert=koolCA.pem # cacert of kool CA
+ ocspuri=http://ocsp.kool.net:8001 # ocsp server
+ ldapserver=ldap.kool.net # default ldap server
+ crluri=http://www.kool.net/kool.crl # crl distribution point
+ crluri2="ldap:///O=Kool, C= .." # crl distribution point #2
+ auto=add # add, ignore
The ca definitions can be monitored via the command
- ipsec auto --listcainfos
+ ipsec auto --listcainfos
- Fixed cosmetic corruption of /proc filesystem by integrating
D. Hugh Redelmeier's freeswan-2.06 kernel fixes.
