1.23 claudio 469: <li>A 30%-50% performance improvement was achieved through libcrypto's
470: partial chains certificate validation feature. Already validated
471: non-inheriting CA certificates are now marked as trusted roots. This
472: way it can be ensured that a leaf's delegated resources are properly
473: covered, and at the same time most validation paths are
474: significantly shortened.
475: <li>Support for gzip and deflate HTTP Content-Encoding compression was
476: added. This allows web servers to send RRDP XML in compressed form,
477: saving around 50% of bandwidth.
478: <li>ASPA support was updated to draft-ietf-sidrops-aspa-profile-16.
479: As part of supporting AFI-agnostic ASPAs, the JSON syntax for
480: Validated ASPA Payloads changed in both filemode and normal output.
481: <li>In filemode (-f option) the applicable manifests are now shown as
482: part of the signature path.
483: <li>A new -P option was added to manually specify a moment in time
484: to use when parsing the validity window of certificates. Useful
485: for regression testing. Default is invocation time of rpki-client.
486: <li>The -A option will now also exclude ASPA data from the JSON output.
487: <li>The synchronisation protocol used to sync the repository is now
488: included in the OpenMetrics output.
489: <li>Improved accounting by tracking objects both by repo and tal.
490: <li>Check whether products listed on a manifest were issued by the same
491: authority as the manifest itself.
492: <li>File modification timestamps of objects retrieved via RRDP are now
493: deterministically set to prepare the on-disk cache for seamless
494: failovers from RRDP to RSYNC.
495: <li>Improved detection of RRDP session desynchronization: a check was
496: added to compare whether the delta hashes associated to previously
497: seen serials are different in newly fetched notification files.
498: <li>Improved handling of RRDP deltas in which objects are published,
499: withdrawn, and published again.
500: <li>Disallow X.509 v2 issuer and subject unique identifiers in certs.
501: RPKI CAs will never issue certificates with V2 unique identifiers.
502: <li>A check to disallow duplicate X.509 certificate extensions was
503: added.
504: <li>A check to disallow empty sets of IP Addresses or AS numbers in RFC
505: 3779 extensions was added.
506: <li>A warning is printed when the CMS signing-time attribute in a Signed
507: Object is missing.
508: <li>Warnings about unrecoverable message digest mismatches now include
509: the manifestNumber to aid debugging the cause.
510: <li>A check was added to disallow multiple RRDP publish elements for the
511: same file in RRDP snapshots. If this error condition is encountered,
512: the RRDP transfer is failed and the RP falls back to rsync.
513: <li>A compliance check for the proper X.509 Certificate version and CRL
514: version was added.
515: <li>A compliance check was added to ensure CMS Signed Objects contain
516: SignedData, in accordance to RFC 6488 section 3 checklist item 1a.
517: <li>Compliance checks were added for the version, KeyUsage, and
518: ExtendedKeyUsage of EE certificates in Manifest, TAK, and GBR Signed
519: Objects.
520: <li>A CMS signing-time value being after the X.509 notAfter timestamp
521: was downgraded from an error to a warning.
522: <li>A bug was fixed in the handling of CA certificates which inherit IP

754: Introduce a transport-level ping facility. This adds
755: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
756: implement a ping capability. These messages use numbers in the "local
757: extensions" number space and are advertised using a "ping@openssh.com"

762: allow forwarding Unix Domain sockets via ssh -W.
763: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
764: add support for configuration tags to ssh(1).
765: This adds a ssh_config(5) "Tag" directive and corresponding
766: "Match tag" predicate that may be used to select blocks of
767: configuration similar to the pf.conf(5) keywords of the same
768: name.
769: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:

780: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
781: AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
782: accept two additional %-expansion sequences: %D which expands to

784: to the addresses and port numbers for the source and destination
785: of the connection.
786: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:

797: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:

1.13 dtucker 808: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
809: Log errors in kex_exchange_identification() with level
1.12 dtucker 810: verbose instead of error to reduce preauth log spam. All of those
811: get logged with a more generic error message by sshpkt_fatal().
812: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
813: correct math for ClientAliveInterval that caused the probes

1.16 jsg 837: remove vestigial support for KRL
1.13 dtucker 838: signatures When the KRL format was originally defined, it included
839: support for signing of KRL objects. However, the code to sign KRLs
1.16 jsg 840: and verify KRL signatures was never completed in OpenSSH. This

851: better validate CASignatureAlgorithms in

853: certificate algorithm names, but these were unusable in practice as
854: OpenSSH does not support CA chains.
855: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
856: make <code>ssh -Q CASignatureAlgorithms</code> only list signature

858: to list all signing algorithms, including certificate algorithms.
859: <li><a href="https://man.openbsd.org/ssh-keyscan.1">ssh-keyscan(1)</a>:

1127: To install, write <i>install74.img</i> or <i>miniroot74.img</i> to a
1128: USB stick, and boot with that drive plugged in.
1129: Make sure you also have the microSD card plugged in that shipped with the
1130: HiFive Unmatched board.
1131: Refer to the instructions in INSTALL.riscv64 for more details.

1136: Burn the image from a mirror site to a CDROM, boot from it, and type
1137: <i>boot cdrom</i>.
1138:
1139: <p>
1140: If this doesn't work, or if you don't have a CDROM drive, you can write
1141: <i>floppy74.img</i> or <i>floppyB74.img</i>
1142: (depending on your machine) to a floppy and boot it with <i>boot
1143: floppy</i>. Refer to INSTALL.sparc64 for details.
1144:
1145: <p>
1146: Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
1147: will most likely fail.
1148:
1149: <p>
1150: You can also write <i>miniroot74.img</i> to the swap partition on
1151: the disk and boot with <i>boot disk:b</i>.
1152:
1153: <p>
1154: If nothing works, you can boot over the network as described in INSTALL.sparc64.

1170: <h3>Notes about the source code</h3>
1171: <p>
1172: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1173: This file contains everything you need except for the kernel sources,
1174: which are in a separate archive.
1175: To extract:
1176: <blockquote><pre>
1177: # <kbd>mkdir -p /usr/src</kbd>
1178: # <kbd>cd /usr/src</kbd>
1179: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1180: </pre></blockquote>
1181: <p>
1182: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1183: This file contains all the kernel sources you need to rebuild kernels.
1184: To extract:
1185: <blockquote><pre>
1186: # <kbd>mkdir -p /usr/src/sys</kbd>
1187: # <kbd>cd /usr/src</kbd>
1188: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1189: </pre></blockquote>
1190: <p>
1191: Both of these trees are a regular CVS checkout. Using these trees it
1192: is possible to get a head-start on using the anoncvs servers as
1193: described <a href="anoncvs.html">here</a>.
1194: Using these files
1195: results in a much faster initial CVS update than you could expect from
1196: a fresh checkout of the full OpenBSD source tree.

1203: <p>
1204: A ports tree archive is also provided. To extract:
1205: <blockquote><pre>
1206: # <kbd>cd /usr</kbd>
1207: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1208: </pre></blockquote>
1209: <p>
1210: Go read the <a href="faq/ports/index.html">ports</a> page
1211: if you know nothing about ports
1212: at this point. This text is not a manual of how to use ports.
1213: Rather, it is a set of notes meant to kickstart the user on the
1214: OpenBSD ports system.
1215: <p>
1216: The <i>ports/</i> directory represents a CVS checkout of our ports.
1217: As with our complete source tree, our ports tree is available via
1218: <a href="anoncvs.html">AnonCVS</a>.
1219: So, in order to keep up to date with the -stable branch, you must make
1220: the <i>ports/</i> tree available on a read-write medium and update the tree
1221: with a command like:
1222: <blockquote><pre>
1223: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1224: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1225: </pre></blockquote>
1226: <p>
1227: [Of course, you must replace the server name here with a nearby anoncvs
1228: server.]
1229: <p>
1230: Note that most ports are available as packages on our mirrors. Updated
1231: ports for the 7.4 release will be made available if problems arise.
1232: <p>
1233: If you're interested in seeing a port added, would like to help out, or just
1234: would like to know more, the mailing list
1235: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
