1.23 claudio 463: <li>A 30%-50% performance improvement was achieved through libcrypto's
464: partial chains certificate validation feature. Already validated
465: non-inheriting CA certificates are now marked as trusted roots. This
466: way it can be ensured that a leaf's delegated resources are properly
467: covered, and at the same time most validation paths are
468: significantly shortened.
469: <li>Support for gzip and deflate HTTP Content-Encoding compression was

471: saving around 50% of bandwidth.
472: <li>ASPA support was updated to draft-ietf-sidrops-aspa-profile-16.
473: As part of supporting AFI-agnostic ASPAs, the JSON syntax for
474: Validated ASPA Payloads changed in both filemode and normal output.
475: <li>In filemode (-f option) the applicable manifests are now shown as
476: part of the signature path.
477: <li>A new -P option was added to manually specify a moment in time
478: to use when parsing the validity window of certificates. Useful
479: for regression testing. Default is invocation time of rpki-client.
480: <li>The -A option will now also exclude ASPA data from the JSON output.
481: <li>The synchronisation protocol used to sync the repository is now
482: included in the OpenMetrics output.
483: <li>Improved accounting by tracking objects both by repo and tal.
484: <li>Check whether products listed on a manifest were issued by the same
485: authority as the manifest itself.
486: <li>File modification timestamps of objects retrieved via RRDP are now
487: deterministically set to prepare the on-disk cache for seamless
488: failovers from RRDP to RSYNC.
489: <li>Improved detection of RRDP session desynchronization: a check was
490: added to compare whether the delta hashes associated to previously
491: seen serials are different in newly fetched notification files.
492: <li>Improved handling of RRDP deltas in which objects are published,
493: withdrawn, and published again.
494: <li>Disallow X.509 v2 issuer and subject unique identifiers in certs.
495: RPKI CAs will never issue certificates with V2 unique identifiers.
496: <li>A check to disallow duplicate X.509 certificate extensions was
497: added.
498: <li>A check to disallow empty sets of IP Addresses or AS numbers in RFC
499: 3779 extensions was added.
500: <li>A warning is printed when the CMS signing-time attribute in a Signed
501: Object is missing.
502: <li>Warnings about unrecoverable message digest mismatches now include
503: the manifestNumber to aid debugging the cause.
504: <li>A check was added to disallow multiple RRDP publish elements for the
505: same file in RRDP snapshots. If this error condition is encountered,
506: the RRDP transfer is failed and the RP falls back to rsync.
507: <li>A compliance check for the proper X.509 Certificate version and CRL
508: version was added.
509: <li>A compliance check was added to ensure CMS Signed Objects contain
510: SignedData, in accordance to RFC 6488 section 3 checklist item 1a.
511: <li>Compliance checks were added for the version, KeyUsage, and
512: ExtendedKeyUsage of EE certificates in Manifest, TAK, and GBR Signed
513: Objects.
514: <li>A CMS signing-time value being after the X.509 notAfter timestamp
515: was downgraded from an error to a warning.

749: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
750: implement a ping capability. These messages use numbers in the "local
751: extensions" number space and are advertised using a "ping@openssh.com"
752: ext-info message with a string version number of "0".
1.13 dtucker 753: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
754: allow override of Subsystem directives in sshd Match blocks.
755: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
756: allow forwarding Unix Domain sockets via ssh -W.
757: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
758: add support for configuration tags to ssh(1).
759: This adds a ssh_config(5) "Tag" directive and corresponding
760: "Match tag" predicate that may be used to select blocks of
761: configuration similar to the pf.conf(5) keywords of the same
762: name.
763: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
764: add a "match localnetwork" predicate. This allows matching
765: on the addresses of available network interfaces and may be used to
766: vary the effective client configuration based on network location.

771: extensions. This defines wire formats for optional KRL extensions
772: and implements parsing of the new submessages. No actual extensions
773: are supported at this point.
774: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
775: AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
776: accept two additional %-expansion sequences: %D which expands to
777: the routing domain of the connected session and %C which expands
778: to the addresses and port numbers for the source and destination
779: of the connection.
780: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:

788: fix scp in SFTP mode recursive upload and download of
789: directories that contain symlinks to other directories. In scp mode,
790: the links would be followed, but in SFTP mode they were not.
791: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:

795: interactive mode for ControlPersist sessions if they

801: and don't delay at all for the "none" authentication mechanism.
1.13 dtucker 802: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
803: Log errors in kex_exchange_identification() with level
1.12 dtucker 804: verbose instead of error to reduce preauth log spam. All of those
805: get logged with a more generic error message by sshpkt_fatal().
806: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
807: correct math for ClientAliveInterval that caused the probes

823: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
824: fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand

1.16 jsg 831: remove vestigial support for KRL
1.13 dtucker 832: signatures When the KRL format was originally defined, it included
833: support for signing of KRL objects. However, the code to sign KRLs
1.16 jsg 834: and verify KRL signatures was never completed in OpenSSH. This
1.13 dtucker 835: release removes the partially-implemented code to verify KRLs.
836: All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in
837: KRL files.

844: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
845: better validate CASignatureAlgorithms in
846: ssh_config and sshd_config. Previously this directive would accept
847: certificate algorithm names, but these were unusable in practice as
848: OpenSSH does not support CA chains.
849: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
850: make <code>ssh -Q CASignatureAlgorithms</code> only list signature
851: algorithms that are valid for CA signing. Previous behaviour was
852: to list all signing algorithms, including certificate algorithms.
853: <li><a href="https://man.openbsd.org/ssh-keyscan.1">ssh-keyscan(1)</a>:

1131: <i>boot cdrom</i>.
1132:
1133: <p>
1134: If this doesn't work, or if you don't have a CDROM drive, you can write
1135: <i>floppy74.img</i> or <i>floppyB74.img</i>
1136: (depending on your machine) to a floppy and boot it with <i>boot
1137: floppy</i>. Refer to INSTALL.sparc64 for details.
1138:
1139: <p>
1140: Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
1141: will most likely fail.
1142:
1143: <p>
1144: You can also write <i>miniroot74.img</i> to the swap partition on
1145: the disk and boot with <i>boot disk:b</i>.
1146:
1147: <p>
1148: If nothing works, you can boot over the network as described in INSTALL.sparc64.

1164: <h3>Notes about the source code</h3>
1165: <p>
1166: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1167: This file contains everything you need except for the kernel sources,
1168: which are in a separate archive.
1169: To extract:
1170: <blockquote><pre>
1171: # <kbd>mkdir -p /usr/src</kbd>
1172: # <kbd>cd /usr/src</kbd>
1173: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1174: </pre></blockquote>
1175: <p>
1176: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1177: This file contains all the kernel sources you need to rebuild kernels.
1178: To extract:
1179: <blockquote><pre>
1180: # <kbd>mkdir -p /usr/src/sys</kbd>
1181: # <kbd>cd /usr/src</kbd>
1182: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1183: </pre></blockquote>
1184: <p>
1185: Both of these trees are a regular CVS checkout. Using these trees it
1186: is possible to get a head-start on using the anoncvs servers as
1187: described <a href="anoncvs.html">here</a>.
1188: Using these files
1189: results in a much faster initial CVS update than you could expect from
1190: a fresh checkout of the full OpenBSD source tree.

1197: <p>
1198: A ports tree archive is also provided. To extract:
1199: <blockquote><pre>
1200: # <kbd>cd /usr</kbd>
1201: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1202: </pre></blockquote>
1203: <p>
1204: Go read the <a href="faq/ports/index.html">ports</a> page
1205: if you know nothing about ports
1206: at this point. This text is not a manual of how to use ports.
1207: Rather, it is a set of notes meant to kickstart the user on the
1208: OpenBSD ports system.
1209: <p>
1210: The <i>ports/</i> directory represents a CVS checkout of our ports.
1211: As with our complete source tree, our ports tree is available via
1212: <a href="anoncvs.html">AnonCVS</a>.
1213: So, in order to keep up to date with the -stable branch, you must make
1214: the <i>ports/</i> tree available on a read-write medium and update the tree
1215: with a command like:
1216: <blockquote><pre>
1217: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1218: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1219: </pre></blockquote>
1220: <p>
1221: [Of course, you must replace the server name here with a nearby anoncvs
1222: server.]
1223: <p>
1224: Note that most ports are available as packages on our mirrors. Updated
1225: ports for the 7.4 release will be made available if problems arise.
1226: <p>
1227: If you're interested in seeing a port added, would like to help out, or just
1228: would like to know more, the mailing list
1229: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
