1.12 benno 450: <li>Allowed more than one CRL URI in certificates.
1.11 benno 451: <li>Do not apply timezone offsets when converting X509 times. X509
452: times are in UTC and comparing them to times in different timezones
453: would cause validity problems.

476: </ul>
477: <li>Improve readability and add various information being printed in
478: verbose mode.
479: <li>Extend filemode (-f) output and print X.509 certificates in PEM

481: <li>Shorten the RRDP I/O idle timeout.
482: <li>Introduce a deadline timer that aborts all repository synchronization
483: after seven eights of timeout (-s). With this rpki-client has improved
1.13 benno 484: chances to complete and produce an output even when a CA is excessively
1.11 benno 485: slow.
486: <li>Abort a currently running RRDP request process when the per-repository
487: timeout is reached.
488: <li>Permit multiple AccessDescription entries in SIA X.509 extensions. While
489: fetching from secondary locations is not yet supported, rpki-client will
1.13 benno 490: not treat occurrence as a fatal error.
1.11 benno 491: <li>Resolve a potential for a race condition in non-atomic RRDP deltas.
492: <li>Fix some memory leaks.
493: <li>Improve compliance with the HTTP protocol specification.
494: </ul>
495:
1.14 benno 496: <li>In <a href="https://man.openbsd.org/ospfd.8">ospfd(8)</a>,
1.11 benno 497: relax the limitations on what is an acceptable unicast IP. There are no
498: more experiments in IPv4 and so there is less reason for network
499: daemons to deny formerly experimental IP space. Multicast IPs
1.13 benno 500: (224/4) and loopback (127/8) are still disallowed.
1.14 benno 501: <li>Added check to <a
502: href="https://man.openbsd.org/acme-client.1">acme-client(1)</a> to
503: ensure the challenge token is turned into a filename that is base64url
504: encoded.

511: <li>Made -X connect SOCKS work with IPv6 adresses in <a href="https://man.openbsd.org/nc.1">nc(1)</a>.

1.1 deraadt 862: upgrade instructions and advice can be found in the

869: <h3>Notes about the source code</h3>
870: <p>
871: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
872: This file contains everything you need except for the kernel sources,
873: which are in a separate archive.
874: To extract:
875: <blockquote><pre>
876: # <kbd>mkdir -p /usr/src</kbd>
877: # <kbd>cd /usr/src</kbd>
878: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
879: </pre></blockquote>
880: <p>
881: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
882: This file contains all the kernel sources you need to rebuild kernels.
883: To extract:
884: <blockquote><pre>
885: # <kbd>mkdir -p /usr/src/sys</kbd>
886: # <kbd>cd /usr/src</kbd>
887: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
888: </pre></blockquote>
889: <p>
890: Both of these trees are a regular CVS checkout. Using these trees it
891: is possible to get a head-start on using the anoncvs servers as
892: described <a href="anoncvs.html">here</a>.
893: Using these files
894: results in a much faster initial CVS update than you could expect from
895: a fresh checkout of the full OpenBSD source tree.

901: <h3>Ports Tree</h3>
902: <p>
903: A ports tree archive is also provided. To extract:
904: <blockquote><pre>
905: # <kbd>cd /usr</kbd>
906: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
907: </pre></blockquote>
908: <p>
909: Go read the <a href="faq/ports/index.html">ports</a> page
910: if you know nothing about ports
911: at this point. This text is not a manual of how to use ports.
912: Rather, it is a set of notes meant to kickstart the user on the
913: OpenBSD ports system.
914: <p>
915: The <i>ports/</i> directory represents a CVS checkout of our ports.
916: As with our complete source tree, our ports tree is available via
917: <a href="anoncvs.html">AnonCVS</a>.
918: So, in order to keep up to date with the -stable branch, you must make
919: the <i>ports/</i> tree available on a read-write medium and update the tree
920: with a command like:
921: <blockquote><pre>
922: # <kbd>cd /usr/ports</kbd>
923: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_2</kbd>
924: </pre></blockquote>
925: <p>
926: [Of course, you must replace the server name here with a nearby anoncvs
927: server.]
928: <p>
929: Note that most ports are available as packages on our mirrors. Updated
930: ports for the 7.2 release will be made available if problems arise.
931: <p>
932: If you're interested in seeing a port added, would like to help out, or just
933: would like to know more, the mailing list
934: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
