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

457: Operators can specify a list of FQDNs which should not be contacted
458: when synchronizing the local cache to the network.

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

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

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

1.1 deraadt 864: upgrade instructions and advice can be found in the

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

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