1.35 benno 98: been standardized in unicode after the original wscons code was
99: written and chose placeholder values.
1.81 benno 100: <li>In <a href="https://man.openbsd.org/wscons.4">wscons(4)</a>,

1.28 benno 691: <li>ARP has a queue of packets that should be sent after name
692: resolution. Neighbor discovery (ND6) did only hold a single packet.
693: Unified the code, added a queue to ND6 and made the code MP safe.
1.31 schwarze 694: <li>Implement a new <a href="https://man.openbsd.org/sysctl.2">sysctl(2)</a>
695: <code>net.inet6.icmp6.nd6_queued</code> to show the number of packets
696: waiting for an ND6 response, analogous to ARP.
1.50 benno 697: <li>When configuring a new IPv6 address on an interface, an upstream router
698: doesn't know where to send traffic. Send an unsolicited
699: neighbor advertisement, as described in RFC9131, to the all-routers
700: multicast address so all routers on the same link will learn the path
701: back to the address.
1.103 schwarze 702: <li>Implement the inbound portion of RFC9131. Let routers create new
703: neighbor cache entries when receiving valid neighbor advertisements.
1.81 benno 704:
705: <li>Initial support for TCP segmentation offload (TSO) and TCP large receive offload (LRO) was implemented:

1.104 schwarze 707: <li>If the driver of a network interface supports TSO,
708: do not chop the packet in the network stack,
1.69 schwarze 709: but pass it down to the interface layer for TSO.

728: interfaces by using TSO and LRO.
1.104 schwarze 729: <li>Enable LRO per default in network
1.78 benno 730: drivers. LRO allows to receive aggregated packets larger than the MTU.
731: Receiving TCP streams becomes much faster. Currently only <a
732: href="https://man.openbsd.org/ix.4">ix(4)</a> and <a
733: href="https://man.openbsd.org/lo.4">lo(4)</a> devices support LRO, and

1.105 schwarze 765: <li>No longer ignore <code>keep state</code> and <code>nat-to</code>
766: actions for unsolicited ICMP error responses.
767: Tighten the rule matching logic so ICMP error responses
768: no longer match <code>keep state</code> rule.
769: In typical scenarios, ICMP errors (if solicited) should match
770: existing state. The change is going to bite firewalls which deal
771: with asymmetric routes. In those cases the <code>keep state</code>
772: action should be relaxed to sloppy or new <code>no state</code>
773: rule to explicitly match ICMP errors should be added.
1.81 benno 774: </ul>

778: wrap around after changing tcp_now() ticks to milliseconds.
1.91 schwarze 779: <li>Add initial support for route-based IPsec VPNs.<br>
780: Rather than use IPsec flows (aka, entries in the IPsec security
1.81 benno 781: policy database) to decide which traffic should be encapsulated in
1.91 schwarze 782: IPsec and sent to a peer, this changes security associations (SAs)
783: so they can also refer to a tunnel interface. When traffic is routed
784: over that tunnel interface, an IPsec SA is looked up and used to
1.81 benno 785: encapsulate traffic before being sent to the peer on the SA. When
1.91 schwarze 786: traffic is received from a peer using an interface SA, the specified
1.81 benno 787: interface is looked up and the packet is handed to it so it looks
788: like packets come out of the tunnel.

1.106 schwarze 790: route-based IPsec VPNs.
1.81 benno 791: <li>Introduce reference counting for TCP syn cache entries.

1.23 claudio 865: <li>A 30%-50% performance improvement was achieved through libcrypto's
866: partial chains certificate validation feature. Already validated
867: non-inheriting CA certificates are now marked as trusted roots. This
868: way it can be ensured that a leaf's delegated resources are properly
869: covered, and at the same time most validation paths are
870: significantly shortened.
871: <li>Support for gzip and deflate HTTP Content-Encoding compression was
872: added. This allows web servers to send RRDP XML in compressed form,
873: saving around 50% of bandwidth.
874: <li>ASPA support was updated to draft-ietf-sidrops-aspa-profile-16.
875: As part of supporting AFI-agnostic ASPAs, the JSON syntax for
876: Validated ASPA Payloads changed in both filemode and normal output.
877: <li>In filemode (-f option) the applicable manifests are now shown as
878: part of the signature path.
879: <li>A new -P option was added to manually specify a moment in time
880: to use when parsing the validity window of certificates. Useful
881: for regression testing. Default is invocation time of rpki-client.
882: <li>The -A option will now also exclude ASPA data from the JSON output.
883: <li>The synchronisation protocol used to sync the repository is now
884: included in the OpenMetrics output.
885: <li>Improved accounting by tracking objects both by repo and tal.
886: <li>Check whether products listed on a manifest were issued by the same
887: authority as the manifest itself.
888: <li>File modification timestamps of objects retrieved via RRDP are now
889: deterministically set to prepare the on-disk cache for seamless
890: failovers from RRDP to RSYNC.
891: <li>Improved detection of RRDP session desynchronization: a check was
892: added to compare whether the delta hashes associated to previously
893: seen serials are different in newly fetched notification files.
894: <li>Improved handling of RRDP deltas in which objects are published,
895: withdrawn, and published again.
896: <li>Disallow X.509 v2 issuer and subject unique identifiers in certs.
897: RPKI CAs will never issue certificates with V2 unique identifiers.
898: <li>A check to disallow duplicate X.509 certificate extensions was
899: added.
900: <li>A check to disallow empty sets of IP Addresses or AS numbers in RFC
901: 3779 extensions was added.
902: <li>A warning is printed when the CMS signing-time attribute in a Signed
903: Object is missing.
904: <li>Warnings about unrecoverable message digest mismatches now include
905: the manifestNumber to aid debugging the cause.
906: <li>A check was added to disallow multiple RRDP publish elements for the
907: same file in RRDP snapshots. If this error condition is encountered,
908: the RRDP transfer is failed and the RP falls back to rsync.
909: <li>A compliance check for the proper X.509 Certificate version and CRL
910: version was added.
911: <li>A compliance check was added to ensure CMS Signed Objects contain
912: SignedData, in accordance to RFC 6488 section 3 checklist item 1a.
913: <li>Compliance checks were added for the version, KeyUsage, and
914: ExtendedKeyUsage of EE certificates in Manifest, TAK, and GBR Signed
915: Objects.
916: <li>A CMS signing-time value being after the X.509 notAfter timestamp
917: was downgraded from an error to a warning.
918: <li>A bug was fixed in the handling of CA certificates which inherit IP
919: resources.
920: <li>A compliance check was added to ensure the X.509 Subject only
921: contains commonName and optionally serialNumber.
922: <li>A compliance check was added to ensure the CMS SignedData and
923: SignerInfo versions to be 3.
924: <li>Fisher-Yates shuffle the order in which Manifest entries are
925: processed. Previously, work items were enqueued in the order the CA

1700: This file contains everything you need except for the kernel sources,
1701: which are in a separate archive.
1702: To extract:
1703: <blockquote><pre>
1704: # <kbd>mkdir -p /usr/src</kbd>
1705: # <kbd>cd /usr/src</kbd>
1706: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1707: </pre></blockquote>
1708: <p>
1709: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1710: This file contains all the kernel sources you need to rebuild kernels.
1711: To extract:
1712: <blockquote><pre>
1713: # <kbd>mkdir -p /usr/src/sys</kbd>
1714: # <kbd>cd /usr/src</kbd>

1719: is possible to get a head-start on using the anoncvs servers as
1720: described <a href="anoncvs.html">here</a>.
1721: Using these files

1738: if you know nothing about ports
1739: at this point. This text is not a manual of how to use ports.
1740: Rather, it is a set of notes meant to kickstart the user on the
1741: OpenBSD ports system.
1742: <p>
1743: The <i>ports/</i> directory represents a CVS checkout of our ports.
1744: As with our complete source tree, our ports tree is available via
1745: <a href="anoncvs.html">AnonCVS</a>.
1746: So, in order to keep up to date with the -stable branch, you must make
1747: the <i>ports/</i> tree available on a read-write medium and update the tree
1748: with a command like:
1749: <blockquote><pre>
1750: # <kbd>cd /usr/ports</kbd>

1.1 deraadt 1752: </pre></blockquote>
1753: <p>
1754: [Of course, you must replace the server name here with a nearby anoncvs
1755: server.]
1756: <p>
1757: Note that most ports are available as packages on our mirrors. Updated
1758: ports for the 7.4 release will be made available if problems arise.
1759: <p>
1760: If you're interested in seeing a port added, would like to help out, or just
1761: would like to know more, the mailing list
1762: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
