173: </ul>
174:
1.2 benno 175: <li><a href="https://man.openbsd.org/rpki-client.8">rpki-client(8)</a> saw these and more changes:
1.1 benno 176: <ul>
1.2 benno 177: <li>Add ability to constrain an RPKI Trust Anchor's effective signing
178: authority to a limited set of Internet numbers. This allows Relying
179: Parties to enjoy the potential benefits of assuming trust, but within
180: a bounded scope.
181: <li>Following a 'failed fetch' (described in RFC 9286), emit a warning and
182: continue with a previously cached Manifest file.
183: <li>Emit a warning when the remote repository presents a Manifest with an
184: unexpected manifestNumber.
185: <li>Improved CRL extension checking.
186: <li>Experimental support for the P-256 signature algorithm.
187: <!-- 8.8. -->
188: <li>A failed manifest fetch could result in a NULL pointer dereference or
189: a use after free.
190: <li>Reject non-conforming RRDP delta elements that contain neither publish
191: nor a withdraw element and fall back to the RRDP snapshot.
192: <li>Refactoring and minor bug fixes in the warning display functions.
193: <!-- 8.9 -->
194: <li>The handling of manifests fetched via rsync or RRDP was reworked to
195: fully conform to RFC 9286.
196: <li>Fix a race condition between closing an idle connection and scheduling a
197: new request on it.
198: <li>The evaluation time specified with -P now also applies to trust anchor
199: certificates.
200: <li>Check that the entire CMS eContent was consumed. Previously, trailing
201: data would be silently discarded on deserialization of products.
202: <li>In file mode do not consider overclaiming intermediate CA certificates
203: as invalid. OAA warning is still issued.
204: <li>Print the revocation time of certificates in file mode.
205: <li>Be more careful when converting OpenSSL numeric identifiers (NIDs)
206: to strings.
207: <!-- 9.0 -->
208: <li>Added support for RPKI Signed Prefix Lists.
209: <li>Added an -x flag to opt into parsing and evaluation of file types that are
210: still considered experimental.
211: <li>Added a metric to track the number of new files that were moved to the
212: validated cache.
213: <li>Ensure that the FileAndHashes list in a Manifest contains no duplicate
214: file names and no duplicate hashes.

634: <h3>How to upgrade</h3>
635: <p>
636: If you already have an OpenBSD 7.4 system, and do not want to reinstall,
637: upgrade instructions and advice can be found in the
638: <a href="faq/upgrade75.html">Upgrade Guide</a>.

642:
643: <section id=sourcecode>
644: <h3>Notes about the source code</h3>
645: <p>
646: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
647: This file contains everything you need except for the kernel sources,
648: which are in a separate archive.
649: To extract:
650: <blockquote><pre>
651: # <kbd>mkdir -p /usr/src</kbd>
652: # <kbd>cd /usr/src</kbd>
653: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
654: </pre></blockquote>
655: <p>
656: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
657: This file contains all the kernel sources you need to rebuild kernels.
658: To extract:
659: <blockquote><pre>
660: # <kbd>mkdir -p /usr/src/sys</kbd>
661: # <kbd>cd /usr/src</kbd>
662: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
663: </pre></blockquote>
664: <p>
665: Both of these trees are a regular CVS checkout. Using these trees it
666: is possible to get a head-start on using the anoncvs servers as
667: described <a href="anoncvs.html">here</a>.
668: Using these files
669: results in a much faster initial CVS update than you could expect from
670: a fresh checkout of the full OpenBSD source tree.

675: <section id=ports>
676: <h3>Ports Tree</h3>
677: <p>
678: A ports tree archive is also provided. To extract:
679: <blockquote><pre>
680: # <kbd>cd /usr</kbd>
681: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
682: </pre></blockquote>
683: <p>
684: Go read the <a href="faq/ports/index.html">ports</a> page
685: if you know nothing about ports
686: at this point. This text is not a manual of how to use ports.
687: Rather, it is a set of notes meant to kickstart the user on the
688: OpenBSD ports system.
689: <p>
690: The <i>ports/</i> directory represents a CVS checkout of our ports.
691: As with our complete source tree, our ports tree is available via
692: <a href="anoncvs.html">AnonCVS</a>.
693: So, in order to keep up to date with the -stable branch, you must make
694: the <i>ports/</i> tree available on a read-write medium and update the tree
695: with a command like:
696: <blockquote><pre>
697: # <kbd>cd /usr/ports</kbd>
698: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_5</kbd>
699: </pre></blockquote>
700: <p>
701: [Of course, you must replace the server name here with a nearby anoncvs
702: server.]
703: <p>
704: Note that most ports are available as packages on our mirrors. Updated
705: ports for the 7.5 release will be made available if problems arise.
706: <p>
707: If you're interested in seeing a port added, would like to help out, or just
708: would like to know more, the mailing list
709: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
