93: IGMP and ICMP6 MLD packets with router alert option.
1.9 bluhm 94: Special allow-opts rules are no longer needed for multicast
95: discovery.
1.16 jsg 96: <li>Implement "show all routes" to print routing tables in
97: <a href="https://man.openbsd.org/ddb.4">ddb(4)</a>.

384: <li><a href="https://man.openbsd.org/rpki-client.8">rpki-client(8)</a> saw some changes:
385: <ul>
1.12 benno 386: <li>Allowed more than one CRL URI in certificates.
1.11 benno 387: <li>Do not apply timezone offsets when converting X509 times. X509
388: times are in UTC and comparing them to times in different timezones
389: would cause validity problems.
390: <li>Add support for an operator-configurable skiplist facility.
391: Operators can specify a list of FQDNs which should not be contacted
392: when synchronizing the local cache to the network.
393: <li>Emit a warning when a RRDP session serial number decreases.
394: <li>DER decoding functions were refactored to leverage ASN.1 templates.
395: <li>Add support to validate & inspect .sig files containing RPKI Signed
396: Checklists in filemode (-f). (draft-ietf-sidrops-rpki-rsc-08)
397: <li>Print various statistics after the completion of the main process.
398: <li>Add support to decode & print TAL (RFC 8630) details in filemode (-f).
399: <li>Emit objects in Concatenated JSON format when filemode (-f) and the JSON
400: output flag (-j) are combined.
1.13 benno 401: <li>Add support for validating Autonomous System Provider Authorization
1.11 benno 402: (ASPA) objects conforming to draft-ietf-sidrops-aspa-profile-10.
403: Validated ASPA payloads are visible in JSON and filemode (-f) output.
404: <li>Set rsync connection I/O idle timeout to 15 seconds.
1.13 benno 405: <li>Unify the maximum idle I/O and connect timeouts for rsync & HTTPS.
1.18 ! jsg 406: <li>rpki-client now performs stricter EE certificate validation:
1.11 benno 407: <ul>
408: <li>Disallow AS Resources extensions in ROA EE certificates.
409: <li>Disallow Subject Information Access (SIA) extensions in RPKI
410: Signed Checklist (RSC) EE certs.
411: <li>Check the resources in ROAs and RSCs against EE certs.
412: </ul>
413: <li>Improve readability and add various information being printed in
414: verbose mode.
415: <li>Extend filemode (-f) output and print X.509 certificates in PEM
416: format when increased verbosity (-vv) is specified.
417: <li>Shorten the RRDP I/O idle timeout.
418: <li>Introduce a deadline timer that aborts all repository synchronization
419: after seven eights of timeout (-s). With this rpki-client has improved
1.13 benno 420: chances to complete and produce an output even when a CA is excessively
1.11 benno 421: slow.
422: <li>Abort a currently running RRDP request process when the per-repository
423: timeout is reached.
424: <li>Permit multiple AccessDescription entries in SIA X.509 extensions. While
425: fetching from secondary locations is not yet supported, rpki-client will
1.13 benno 426: not treat occurrence as a fatal error.
1.11 benno 427: <li>Resolve a potential for a race condition in non-atomic RRDP deltas.
428: <li>Fix some memory leaks.
429: <li>Improve compliance with the HTTP protocol specification.
430: </ul>
431:
1.14 benno 432: <li>In <a href="https://man.openbsd.org/ospfd.8">ospfd(8)</a>,
1.11 benno 433: relax the limitations on what is an acceptable unicast IP. There are no
434: more experiments in IPv4 and so there is less reason for network
435: daemons to deny formerly experimental IP space. Multicast IPs
1.13 benno 436: (224/4) and loopback (127/8) are still disallowed.
1.14 benno 437: <li>Added check to <a

819: <h3>Ports Tree</h3>
820: <p>
821: A ports tree archive is also provided. To extract:
822: <blockquote><pre>
823: # <kbd>cd /usr</kbd>
824: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
825: </pre></blockquote>
826: <p>
827: Go read the <a href="faq/ports/index.html">ports</a> page
828: if you know nothing about ports
829: at this point. This text is not a manual of how to use ports.
830: Rather, it is a set of notes meant to kickstart the user on the
831: OpenBSD ports system.
832: <p>
833: The <i>ports/</i> directory represents a CVS checkout of our ports.
834: As with our complete source tree, our ports tree is available via
835: <a href="anoncvs.html">AnonCVS</a>.
836: So, in order to keep up to date with the -stable branch, you must make
837: the <i>ports/</i> tree available on a read-write medium and update the tree
838: with a command like:
839: <blockquote><pre>
840: # <kbd>cd /usr/ports</kbd>
841: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_2</kbd>
842: </pre></blockquote>
843: <p>
844: [Of course, you must replace the server name here with a nearby anoncvs
845: server.]
846: <p>
847: Note that most ports are available as packages on our mirrors. Updated
848: ports for the 7.2 release will be made available if problems arise.
849: <p>
850: If you're interested in seeing a port added, would like to help out, or just
851: would like to know more, the mailing list
852: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
