544: partial chains certificate validation feature. Already validated
545: non-inheriting CA certificates are now marked as trusted roots. This
546: way it can be ensured that a leaf's delegated resources are properly
547: covered, and at the same time most validation paths are

551: saving around 50% of bandwidth.
552: <li>ASPA support was updated to draft-ietf-sidrops-aspa-profile-16.
553: As part of supporting AFI-agnostic ASPAs, the JSON syntax for
554: Validated ASPA Payloads changed in both filemode and normal output.
555: <li>In filemode (-f option) the applicable manifests are now shown as
556: part of the signature path.
557: <li>A new -P option was added to manually specify a moment in time
558: to use when parsing the validity window of certificates. Useful
559: for regression testing. Default is invocation time of rpki-client.
560: <li>The -A option will now also exclude ASPA data from the JSON output.
561: <li>The synchronisation protocol used to sync the repository is now
562: included in the OpenMetrics output.
563: <li>Improved accounting by tracking objects both by repo and tal.
564: <li>Check whether products listed on a manifest were issued by the same
565: authority as the manifest itself.
566: <li>File modification timestamps of objects retrieved via RRDP are now
567: deterministically set to prepare the on-disk cache for seamless
568: failovers from RRDP to RSYNC.
569: <li>Improved detection of RRDP session desynchronization: a check was
570: added to compare whether the delta hashes associated to previously
571: seen serials are different in newly fetched notification files.
572: <li>Improved handling of RRDP deltas in which objects are published,
573: withdrawn, and published again.
574: <li>Disallow X.509 v2 issuer and subject unique identifiers in certs.
575: RPKI CAs will never issue certificates with V2 unique identifiers.
576: <li>A check to disallow duplicate X.509 certificate extensions was
577: added.
578: <li>A check to disallow empty sets of IP Addresses or AS numbers in RFC

581: Object is missing.
582: <li>Warnings about unrecoverable message digest mismatches now include
583: the manifestNumber to aid debugging the cause.
584: <li>A check was added to disallow multiple RRDP publish elements for the
585: same file in RRDP snapshots. If this error condition is encountered,
586: the RRDP transfer is failed and the RP falls back to rsync.
587: <li>A compliance check for the proper X.509 Certificate version and CRL
588: version was added.
589: <li>A compliance check was added to ensure CMS Signed Objects contain
590: SignedData, in accordance to RFC 6488 section 3 checklist item 1a.
591: <li>Compliance checks were added for the version, KeyUsage, and
592: ExtendedKeyUsage of EE certificates in Manifest, TAK, and GBR Signed
593: Objects.
594: <li>A CMS signing-time value being after the X.509 notAfter timestamp
595: was downgraded from an error to a warning.
596: <li>A bug was fixed in the handling of CA certificates which inherit IP
597: resources.
598: <li>A compliance check was added to ensure the X.509 Subject only
599: contains commonName and optionally serialNumber.
600: <li>A compliance check was added to ensure the CMS SignedData and
601: SignerInfo versions to be 3.
602: <li>Fisher-Yates shuffle the order in which Manifest entries are

1.1 deraadt 823: <ul>
1.12 dtucker 824: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
825: generate Ed25519 keys by default. Ed25519 public keys
826: are very convenient due to their small size. Ed25519 keys are
827: specified in RFC 8709 and OpenSSH has supported them since version 6.5
828: (January 2014).
829: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
830: the Subsystem directive now accurately preserves quoting of
831: subsystem commands and arguments. This may change behaviour for exotic
832: configurations, but the most common subsystem configuration
833: (sftp-server) is unlikely to be affected.
1.13 dtucker 834: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
835: PKCS#11 modules must now be specified by their full
836: paths. Previously dlopen(3) could search for them in system
837: library directories.
1.1 deraadt 838: </ul>
1.12 dtucker 839: <li>New features
1.1 deraadt 840: <ul>
1.12 dtucker 841: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
842: add keystroke timing obfuscation to the client. This attempts
843: to hide inter-keystroke timings by sending interactive traffic at
844: fixed intervals (default: every 20ms) when there is only a small
845: amount of data being sent. It also sends fake "chaff" keystrokes for
846: a random interval after the last real keystroke. These are
847: controlled by a new ssh_config ObscureKeystrokeTiming keyword.
848: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
849: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
850: Introduce a transport-level ping facility. This adds
851: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
852: implement a ping capability. These messages use numbers in the "local
853: extensions" number space and are advertised using a "ping@openssh.com"
854: ext-info message with a string version number of "0".
1.13 dtucker 855: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
856: allow override of Subsystem directives in sshd Match blocks.
857: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
858: allow forwarding Unix Domain sockets via ssh -W.
859: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
860: add support for configuration tags to ssh(1).
861: This adds a ssh_config(5) "Tag" directive and corresponding
862: "Match tag" predicate that may be used to select blocks of
863: configuration similar to the pf.conf(5) keywords of the same
864: name.
865: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
866: add a "match localnetwork" predicate. This allows matching
867: on the addresses of available network interfaces and may be used to
868: vary the effective client configuration based on network location.
869: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
870: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
871: <a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
872: infrastructure support for KRL
873: extensions. This defines wire formats for optional KRL extensions
874: and implements parsing of the new submessages. No actual extensions
875: are supported at this point.
876: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
877: AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
878: accept two additional %-expansion sequences: %D which expands to
879: the routing domain of the connected session and %C which expands
880: to the addresses and port numbers for the source and destination
881: of the connection.
882: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
883: increase the default work factor (rounds) for the
884: bcrypt KDF used to derive symmetric encryption keys for passphrase
885: protected key files by 50%.
1.1 deraadt 886: </ul>
887: <li>Bugfixes
888: <ul>
1.12 dtucker 889: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
890: fix scp in SFTP mode recursive upload and download of
891: directories that contain symlinks to other directories. In scp mode,
892: the links would be followed, but in SFTP mode they were not.
893: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
894: handle cr+lf (instead of just cr) line endings in
895: sshsig signature files.
896: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
897: interactive mode for ControlPersist sessions if they
898: originally requested a tty.
899: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
900: make PerSourceMaxStartups first-match-wins
901: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
902: limit artificial login delay to a reasonable maximum (5s)
903: and don't delay at all for the "none" authentication mechanism.
1.13 dtucker 904: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
905: Log errors in kex_exchange_identification() with level
1.12 dtucker 906: verbose instead of error to reduce preauth log spam. All of those
907: get logged with a more generic error message by sshpkt_fatal().
908: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
909: correct math for ClientAliveInterval that caused the probes
910: to be sent less frequently than configured.
1.13 dtucker 911: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
912: improve isolation between loaded PKCS#11 modules
913: by running separate ssh-pkcs11-helpers for each loaded provider.
914: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
915: make -f (fork after authentication) work correctly with
916: multiplexed connections, including ControlPersist.
917: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
918: make ConnectTimeout apply to multiplexing sockets and not
919: just to network connections.
920: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
921: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
922: improve defences against invalid PKCS#11
923: modules being loaded by checking that the requested module
924: contains the required symbol before loading it.
925: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
926: fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand
927: appears before it in sshd_config. Since OpenSSH 8.7 the
928: AuthorizedPrincipalsCommand directive was incorrectly ignored in
929: this situation.
930: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
931: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
932: <a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1.16 jsg 933: remove vestigial support for KRL
1.13 dtucker 934: signatures When the KRL format was originally defined, it included
935: support for signing of KRL objects. However, the code to sign KRLs
1.16 jsg 936: and verify KRL signatures was never completed in OpenSSH. This
1.13 dtucker 937: release removes the partially-implemented code to verify KRLs.
938: All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in
939: KRL files.
940: <li>All: fix a number of memory leaks and unreachable/harmless integer
941: overflows.
942: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
943: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
944: don't truncate strings logged from PKCS#11 modules
945: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
946: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
947: better validate CASignatureAlgorithms in
948: ssh_config and sshd_config. Previously this directive would accept
949: certificate algorithm names, but these were unusable in practice as
950: OpenSSH does not support CA chains.
951: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
952: make <code>ssh -Q CASignatureAlgorithms</code> only list signature
953: algorithms that are valid for CA signing. Previous behaviour was
954: to list all signing algorithms, including certificate algorithms.
955: <li><a href="https://man.openbsd.org/ssh-keyscan.1">ssh-keyscan(1)</a>:
956: gracefully handle systems where rlimits or the
957: maximum number of open files is larger than INT_MAX
958: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
959: fix "no comment" not showing on when running
960: <code>ssh-keygen -l</code> on multiple keys where one has a comment
961: and other following keys do not.
962: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>,
1.14 dtucker 963: <a href="https://man.openbsd.org/sftp.1">sftp(1)</a>:
1.13 dtucker 964: adjust ftruncate() logic to handle servers that
965: reorder requests. Previously, if the server reordered requests then
966: the resultant file would be erroneously truncated.
967: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
968: don't incorrectly disable hostname canonicalization when
1.16 jsg 969: CanonicalizeHostname=yes and ProxyJump was explicitly set to
1.13 dtucker 970: "none".
971: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
972: when copying local to remote, check that the source file

1.3 jsg 1259: If you already have an OpenBSD 7.3 system, and do not want to reinstall,
1.1 deraadt 1260: upgrade instructions and advice can be found in the

1266: <section id=sourcecode>
1267: <h3>Notes about the source code</h3>
1268: <p>
1269: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1270: This file contains everything you need except for the kernel sources,
1271: which are in a separate archive.
1272: To extract:
1273: <blockquote><pre>
1274: # <kbd>mkdir -p /usr/src</kbd>
1275: # <kbd>cd /usr/src</kbd>
1276: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1277: </pre></blockquote>
1278: <p>
1279: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1280: This file contains all the kernel sources you need to rebuild kernels.
1281: To extract:
1282: <blockquote><pre>
1283: # <kbd>mkdir -p /usr/src/sys</kbd>
1284: # <kbd>cd /usr/src</kbd>
1285: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1286: </pre></blockquote>
1287: <p>
1288: Both of these trees are a regular CVS checkout. Using these trees it
1289: is possible to get a head-start on using the anoncvs servers as
1290: described <a href="anoncvs.html">here</a>.
1291: Using these files
1292: results in a much faster initial CVS update than you could expect from
1293: a fresh checkout of the full OpenBSD source tree.

1299: <h3>Ports Tree</h3>
1300: <p>
1301: A ports tree archive is also provided. To extract:
1302: <blockquote><pre>
1303: # <kbd>cd /usr</kbd>
1304: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1305: </pre></blockquote>
1306: <p>
1307: Go read the <a href="faq/ports/index.html">ports</a> page
1308: if you know nothing about ports
1309: at this point. This text is not a manual of how to use ports.
1310: Rather, it is a set of notes meant to kickstart the user on the
1311: OpenBSD ports system.
1312: <p>
1313: The <i>ports/</i> directory represents a CVS checkout of our ports.
1314: As with our complete source tree, our ports tree is available via
1315: <a href="anoncvs.html">AnonCVS</a>.
1316: So, in order to keep up to date with the -stable branch, you must make
1317: the <i>ports/</i> tree available on a read-write medium and update the tree
1318: with a command like:
1319: <blockquote><pre>
1320: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1321: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1322: </pre></blockquote>
1323: <p>
1324: [Of course, you must replace the server name here with a nearby anoncvs
1325: server.]
1326: <p>
1327: Note that most ports are available as packages on our mirrors. Updated
1328: ports for the 7.4 release will be made available if problems arise.
1329: <p>
1330: If you're interested in seeing a port added, would like to help out, or just
1331: would like to know more, the mailing list
1332: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
