1.23 claudio 468: <li>A 30%-50% performance improvement was achieved through libcrypto's
469: partial chains certificate validation feature. Already validated
470: non-inheriting CA certificates are now marked as trusted roots. This
471: way it can be ensured that a leaf's delegated resources are properly
472: covered, and at the same time most validation paths are
473: significantly shortened.
474: <li>Support for gzip and deflate HTTP Content-Encoding compression was
475: added. This allows web servers to send RRDP XML in compressed form,
476: saving around 50% of bandwidth.
477: <li>ASPA support was updated to draft-ietf-sidrops-aspa-profile-16.
478: As part of supporting AFI-agnostic ASPAs, the JSON syntax for
479: Validated ASPA Payloads changed in both filemode and normal output.
480: <li>In filemode (-f option) the applicable manifests are now shown as
481: part of the signature path.
482: <li>A new -P option was added to manually specify a moment in time
483: to use when parsing the validity window of certificates. Useful
484: for regression testing. Default is invocation time of rpki-client.
485: <li>The -A option will now also exclude ASPA data from the JSON output.
486: <li>The synchronisation protocol used to sync the repository is now
487: included in the OpenMetrics output.
488: <li>Improved accounting by tracking objects both by repo and tal.
489: <li>Check whether products listed on a manifest were issued by the same
490: authority as the manifest itself.
491: <li>File modification timestamps of objects retrieved via RRDP are now
492: deterministically set to prepare the on-disk cache for seamless
493: failovers from RRDP to RSYNC.
494: <li>Improved detection of RRDP session desynchronization: a check was
495: added to compare whether the delta hashes associated to previously
496: seen serials are different in newly fetched notification files.
497: <li>Improved handling of RRDP deltas in which objects are published,
498: withdrawn, and published again.
499: <li>Disallow X.509 v2 issuer and subject unique identifiers in certs.
500: RPKI CAs will never issue certificates with V2 unique identifiers.
501: <li>A check to disallow duplicate X.509 certificate extensions was
502: added.
503: <li>A check to disallow empty sets of IP Addresses or AS numbers in RFC
504: 3779 extensions was added.
505: <li>A warning is printed when the CMS signing-time attribute in a Signed
506: Object is missing.
507: <li>Warnings about unrecoverable message digest mismatches now include
508: the manifestNumber to aid debugging the cause.
509: <li>A check was added to disallow multiple RRDP publish elements for the
510: same file in RRDP snapshots. If this error condition is encountered,
511: the RRDP transfer is failed and the RP falls back to rsync.
512: <li>A compliance check for the proper X.509 Certificate version and CRL
513: version was added.
514: <li>A compliance check was added to ensure CMS Signed Objects contain
515: SignedData, in accordance to RFC 6488 section 3 checklist item 1a.
516: <li>Compliance checks were added for the version, KeyUsage, and
517: ExtendedKeyUsage of EE certificates in Manifest, TAK, and GBR Signed
518: Objects.
519: <li>A CMS signing-time value being after the X.509 notAfter timestamp
520: was downgraded from an error to a warning.
521: <li>A bug was fixed in the handling of CA certificates which inherit IP

749: paths. Previously dlopen(3) could search for them in system
750: library directories.
1.1 deraadt 751: </ul>
1.12 dtucker 752: <li>New features
1.1 deraadt 753: <ul>
1.12 dtucker 754: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
755: add keystroke timing obfuscation to the client. This attempts
756: to hide inter-keystroke timings by sending interactive traffic at
757: fixed intervals (default: every 20ms) when there is only a small
758: amount of data being sent. It also sends fake "chaff" keystrokes for
759: a random interval after the last real keystroke. These are
760: controlled by a new ssh_config ObscureKeystrokeTiming keyword.
761: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
762: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
763: Introduce a transport-level ping facility. This adds
764: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
765: implement a ping capability. These messages use numbers in the "local
766: extensions" number space and are advertised using a "ping@openssh.com"
767: ext-info message with a string version number of "0".
1.13 dtucker 768: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
769: allow override of Subsystem directives in sshd Match blocks.
770: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
771: allow forwarding Unix Domain sockets via ssh -W.
772: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
773: add support for configuration tags to ssh(1).
774: This adds a ssh_config(5) "Tag" directive and corresponding
775: "Match tag" predicate that may be used to select blocks of
776: configuration similar to the pf.conf(5) keywords of the same
777: name.
778: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
779: add a "match localnetwork" predicate. This allows matching
780: on the addresses of available network interfaces and may be used to
781: vary the effective client configuration based on network location.
782: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
783: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
784: <a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
785: infrastructure support for KRL
786: extensions. This defines wire formats for optional KRL extensions
787: and implements parsing of the new submessages. No actual extensions
788: are supported at this point.
789: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
790: AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
791: accept two additional %-expansion sequences: %D which expands to
792: the routing domain of the connected session and %C which expands
793: to the addresses and port numbers for the source and destination
794: of the connection.
795: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
796: increase the default work factor (rounds) for the
797: bcrypt KDF used to derive symmetric encryption keys for passphrase
798: protected key files by 50%.
1.1 deraadt 799: </ul>
800: <li>Bugfixes
801: <ul>
1.12 dtucker 802: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
803: fix scp in SFTP mode recursive upload and download of
804: directories that contain symlinks to other directories. In scp mode,
805: the links would be followed, but in SFTP mode they were not.
806: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
807: handle cr+lf (instead of just cr) line endings in
808: sshsig signature files.
809: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
810: interactive mode for ControlPersist sessions if they
811: originally requested a tty.
812: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
813: make PerSourceMaxStartups first-match-wins
814: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
815: limit artificial login delay to a reasonable maximum (5s)
816: and don't delay at all for the "none" authentication mechanism.
1.13 dtucker 817: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
818: Log errors in kex_exchange_identification() with level
1.12 dtucker 819: verbose instead of error to reduce preauth log spam. All of those
820: get logged with a more generic error message by sshpkt_fatal().
821: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
822: correct math for ClientAliveInterval that caused the probes
823: to be sent less frequently than configured.
1.13 dtucker 824: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
825: improve isolation between loaded PKCS#11 modules
826: by running separate ssh-pkcs11-helpers for each loaded provider.
827: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
828: make -f (fork after authentication) work correctly with
829: multiplexed connections, including ControlPersist.
830: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
831: make ConnectTimeout apply to multiplexing sockets and not
832: just to network connections.
833: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
834: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
835: improve defences against invalid PKCS#11
836: modules being loaded by checking that the requested module
837: contains the required symbol before loading it.
838: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
839: fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand
840: appears before it in sshd_config. Since OpenSSH 8.7 the
841: AuthorizedPrincipalsCommand directive was incorrectly ignored in
842: this situation.
843: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
844: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
845: <a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1.16 jsg 846: remove vestigial support for KRL
1.13 dtucker 847: signatures When the KRL format was originally defined, it included
848: support for signing of KRL objects. However, the code to sign KRLs
1.16 jsg 849: and verify KRL signatures was never completed in OpenSSH. This
1.13 dtucker 850: release removes the partially-implemented code to verify KRLs.
851: All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in
852: KRL files.
853: <li>All: fix a number of memory leaks and unreachable/harmless integer
854: overflows.
855: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
856: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
857: don't truncate strings logged from PKCS#11 modules
858: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
859: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
860: better validate CASignatureAlgorithms in
861: ssh_config and sshd_config. Previously this directive would accept
862: certificate algorithm names, but these were unusable in practice as
863: OpenSSH does not support CA chains.
864: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
865: make <code>ssh -Q CASignatureAlgorithms</code> only list signature
866: algorithms that are valid for CA signing. Previous behaviour was
867: to list all signing algorithms, including certificate algorithms.
868: <li><a href="https://man.openbsd.org/ssh-keyscan.1">ssh-keyscan(1)</a>:
869: gracefully handle systems where rlimits or the
870: maximum number of open files is larger than INT_MAX
871: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
872: fix "no comment" not showing on when running
873: <code>ssh-keygen -l</code> on multiple keys where one has a comment
874: and other following keys do not.
875: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>,
1.14 dtucker 876: <a href="https://man.openbsd.org/sftp.1">sftp(1)</a>:
1.13 dtucker 877: adjust ftruncate() logic to handle servers that
878: reorder requests. Previously, if the server reordered requests then
879: the resultant file would be erroneously truncated.
880: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
881: don't incorrectly disable hostname canonicalization when
1.16 jsg 882: CanonicalizeHostname=yes and ProxyJump was explicitly set to
1.13 dtucker 883: "none".
884: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
885: when copying local to remote, check that the source file
886: exists before opening an SFTP connection to the server.

1179: <h3>Notes about the source code</h3>
1180: <p>
1181: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1182: This file contains everything you need except for the kernel sources,
1183: which are in a separate archive.
1184: To extract:
1185: <blockquote><pre>
1186: # <kbd>mkdir -p /usr/src</kbd>
1187: # <kbd>cd /usr/src</kbd>
1188: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1189: </pre></blockquote>
1190: <p>
1191: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1192: This file contains all the kernel sources you need to rebuild kernels.
1193: To extract:
1194: <blockquote><pre>
1195: # <kbd>mkdir -p /usr/src/sys</kbd>
1196: # <kbd>cd /usr/src</kbd>
1197: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1198: </pre></blockquote>
1199: <p>
1200: Both of these trees are a regular CVS checkout. Using these trees it
1201: is possible to get a head-start on using the anoncvs servers as
1202: described <a href="anoncvs.html">here</a>.
1203: Using these files
1204: results in a much faster initial CVS update than you could expect from
1205: a fresh checkout of the full OpenBSD source tree.

1214: <blockquote><pre>
1215: # <kbd>cd /usr</kbd>
1216: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1217: </pre></blockquote>
1218: <p>
1219: Go read the <a href="faq/ports/index.html">ports</a> page
1220: if you know nothing about ports
1221: at this point. This text is not a manual of how to use ports.
1222: Rather, it is a set of notes meant to kickstart the user on the
1223: OpenBSD ports system.
1224: <p>
1225: The <i>ports/</i> directory represents a CVS checkout of our ports.
1226: As with our complete source tree, our ports tree is available via
1227: <a href="anoncvs.html">AnonCVS</a>.
1228: So, in order to keep up to date with the -stable branch, you must make
1229: the <i>ports/</i> tree available on a read-write medium and update the tree
1230: with a command like:
1231: <blockquote><pre>
1232: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1233: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1234: </pre></blockquote>
1235: <p>
1236: [Of course, you must replace the server name here with a nearby anoncvs
1237: server.]
1238: <p>
1239: Note that most ports are available as packages on our mirrors. Updated
1240: ports for the 7.4 release will be made available if problems arise.
1241: <p>
1242: If you're interested in seeing a port added, would like to help out, or just
1243: would like to know more, the mailing list
1244: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
