641: partial chains certificate validation feature. Already validated
642: non-inheriting CA certificates are now marked as trusted roots. This
643: way it can be ensured that a leaf's delegated resources are properly
644: covered, and at the same time most validation paths are
645: significantly shortened.
646: <li>Support for gzip and deflate HTTP Content-Encoding compression was

648: saving around 50% of bandwidth.
649: <li>ASPA support was updated to draft-ietf-sidrops-aspa-profile-16.
650: As part of supporting AFI-agnostic ASPAs, the JSON syntax for
651: Validated ASPA Payloads changed in both filemode and normal output.
652: <li>In filemode (-f option) the applicable manifests are now shown as
653: part of the signature path.
654: <li>A new -P option was added to manually specify a moment in time
655: to use when parsing the validity window of certificates. Useful
656: for regression testing. Default is invocation time of rpki-client.
657: <li>The -A option will now also exclude ASPA data from the JSON output.
658: <li>The synchronisation protocol used to sync the repository is now
659: included in the OpenMetrics output.
660: <li>Improved accounting by tracking objects both by repo and tal.
661: <li>Check whether products listed on a manifest were issued by the same
662: authority as the manifest itself.
663: <li>File modification timestamps of objects retrieved via RRDP are now
664: deterministically set to prepare the on-disk cache for seamless
665: failovers from RRDP to RSYNC.
666: <li>Improved detection of RRDP session desynchronization: a check was
667: added to compare whether the delta hashes associated to previously
668: seen serials are different in newly fetched notification files.
669: <li>Improved handling of RRDP deltas in which objects are published,
670: withdrawn, and published again.
671: <li>Disallow X.509 v2 issuer and subject unique identifiers in certs.
672: RPKI CAs will never issue certificates with V2 unique identifiers.
673: <li>A check to disallow duplicate X.509 certificate extensions was
674: added.
675: <li>A check to disallow empty sets of IP Addresses or AS numbers in RFC

678: Object is missing.
679: <li>Warnings about unrecoverable message digest mismatches now include
680: the manifestNumber to aid debugging the cause.
681: <li>A check was added to disallow multiple RRDP publish elements for the
682: same file in RRDP snapshots. If this error condition is encountered,
683: the RRDP transfer is failed and the RP falls back to rsync.
684: <li>A compliance check for the proper X.509 Certificate version and CRL
685: version was added.
686: <li>A compliance check was added to ensure CMS Signed Objects contain
687: SignedData, in accordance to RFC 6488 section 3 checklist item 1a.
688: <li>Compliance checks were added for the version, KeyUsage, and
689: ExtendedKeyUsage of EE certificates in Manifest, TAK, and GBR Signed
690: Objects.
691: <li>A CMS signing-time value being after the X.509 notAfter timestamp
692: was downgraded from an error to a warning.
693: <li>A bug was fixed in the handling of CA certificates which inherit IP
694: resources.
695: <li>A compliance check was added to ensure the X.509 Subject only

783: be selected for use.
784: <li>BN_is_prime{,_fasttest}_ex() refuse to check numbers larger than
785: 32 kbits for primality. This mitigates various DoS vectors.

797: <li>Internal compatibility function symbols are no longer exported from
798: libcrypto. Instead, the libcompat library is linked to libcrypto,
799: libssl, and libtls separately. This increases size a little, but
800: ensures that the libraries are not exporting symbols to programs
801: unintentionally.
802: <li>Selective removal of CET implementation on platforms where it is
803: not supported (macOS).
804: <li>Integrated four more tests.

851: <li>In X509_VERIFY_PARAM_inherit() copy hostflags independently of the
852: host list.
853: <li>Made CRYPTO_get_ex_new_index() not return 0 to allow applications

967: fixed intervals (default: every 20ms) when there is only a small

1393: This file contains everything you need except for the kernel sources,
1394: which are in a separate archive.
1395: To extract:
1396: <blockquote><pre>
1397: # <kbd>mkdir -p /usr/src</kbd>
1398: # <kbd>cd /usr/src</kbd>
1399: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1400: </pre></blockquote>
1401: <p>
1402: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1403: This file contains all the kernel sources you need to rebuild kernels.
1404: To extract:
1405: <blockquote><pre>
1406: # <kbd>mkdir -p /usr/src/sys</kbd>
1407: # <kbd>cd /usr/src</kbd>
1408: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>

1412: is possible to get a head-start on using the anoncvs servers as
1413: described <a href="anoncvs.html">here</a>.
1414: Using these files

1431: if you know nothing about ports
1432: at this point. This text is not a manual of how to use ports.
1433: Rather, it is a set of notes meant to kickstart the user on the
1434: OpenBSD ports system.
1435: <p>
1436: The <i>ports/</i> directory represents a CVS checkout of our ports.
1437: As with our complete source tree, our ports tree is available via
1438: <a href="anoncvs.html">AnonCVS</a>.
1439: So, in order to keep up to date with the -stable branch, you must make
1440: the <i>ports/</i> tree available on a read-write medium and update the tree
1441: with a command like:
1442: <blockquote><pre>
1443: # <kbd>cd /usr/ports</kbd>

1.1 deraadt 1445: </pre></blockquote>
1446: <p>
1447: [Of course, you must replace the server name here with a nearby anoncvs
1448: server.]
1449: <p>
1450: Note that most ports are available as packages on our mirrors. Updated
1451: ports for the 7.4 release will be made available if problems arise.
1452: <p>
1453: If you're interested in seeing a port added, would like to help out, or just
1454: would like to know more, the mailing list
1455: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
