515: partial chains certificate validation feature. Already validated
516: non-inheriting CA certificates are now marked as trusted roots. This
517: way it can be ensured that a leaf's delegated resources are properly
518: covered, and at the same time most validation paths are
519: significantly shortened.
520: <li>Support for gzip and deflate HTTP Content-Encoding compression was

522: saving around 50% of bandwidth.
523: <li>ASPA support was updated to draft-ietf-sidrops-aspa-profile-16.
524: As part of supporting AFI-agnostic ASPAs, the JSON syntax for
525: Validated ASPA Payloads changed in both filemode and normal output.
526: <li>In filemode (-f option) the applicable manifests are now shown as
527: part of the signature path.
528: <li>A new -P option was added to manually specify a moment in time
529: to use when parsing the validity window of certificates. Useful
530: for regression testing. Default is invocation time of rpki-client.
531: <li>The -A option will now also exclude ASPA data from the JSON output.
532: <li>The synchronisation protocol used to sync the repository is now
533: included in the OpenMetrics output.
534: <li>Improved accounting by tracking objects both by repo and tal.
535: <li>Check whether products listed on a manifest were issued by the same
536: authority as the manifest itself.
537: <li>File modification timestamps of objects retrieved via RRDP are now
538: deterministically set to prepare the on-disk cache for seamless
539: failovers from RRDP to RSYNC.
540: <li>Improved detection of RRDP session desynchronization: a check was
541: added to compare whether the delta hashes associated to previously
542: seen serials are different in newly fetched notification files.
543: <li>Improved handling of RRDP deltas in which objects are published,
544: withdrawn, and published again.
545: <li>Disallow X.509 v2 issuer and subject unique identifiers in certs.
546: RPKI CAs will never issue certificates with V2 unique identifiers.
547: <li>A check to disallow duplicate X.509 certificate extensions was
548: added.
549: <li>A check to disallow empty sets of IP Addresses or AS numbers in RFC

552: Object is missing.
553: <li>Warnings about unrecoverable message digest mismatches now include
554: the manifestNumber to aid debugging the cause.
555: <li>A check was added to disallow multiple RRDP publish elements for the
556: same file in RRDP snapshots. If this error condition is encountered,
557: the RRDP transfer is failed and the RP falls back to rsync.
558: <li>A compliance check for the proper X.509 Certificate version and CRL
559: version was added.
560: <li>A compliance check was added to ensure CMS Signed Objects contain
561: SignedData, in accordance to RFC 6488 section 3 checklist item 1a.
562: <li>Compliance checks were added for the version, KeyUsage, and
563: ExtendedKeyUsage of EE certificates in Manifest, TAK, and GBR Signed
564: Objects.
565: <li>A CMS signing-time value being after the X.509 notAfter timestamp
566: was downgraded from an error to a warning.
567: <li>A bug was fixed in the handling of CA certificates which inherit IP
568: resources.
569: <li>A compliance check was added to ensure the X.509 Subject only
570: contains commonName and optionally serialNumber.

572: SignerInfo versions to be 3.
573: <li>Fisher-Yates shuffle the order in which Manifest entries are
574: processed. Previously, work items were enqueued in the order the CA

1.1 deraadt 782: <ul>
1.12 dtucker 783: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
784: generate Ed25519 keys by default. Ed25519 public keys
785: are very convenient due to their small size. Ed25519 keys are
786: specified in RFC 8709 and OpenSSH has supported them since version 6.5
787: (January 2014).
788: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
789: the Subsystem directive now accurately preserves quoting of
790: subsystem commands and arguments. This may change behaviour for exotic
791: configurations, but the most common subsystem configuration
792: (sftp-server) is unlikely to be affected.
1.13 dtucker 793: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
794: PKCS#11 modules must now be specified by their full
795: paths. Previously dlopen(3) could search for them in system
796: library directories.
1.1 deraadt 797: </ul>
1.12 dtucker 798: <li>New features
1.1 deraadt 799: <ul>
1.12 dtucker 800: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
801: add keystroke timing obfuscation to the client. This attempts
802: to hide inter-keystroke timings by sending interactive traffic at
803: fixed intervals (default: every 20ms) when there is only a small
804: amount of data being sent. It also sends fake "chaff" keystrokes for
805: a random interval after the last real keystroke. These are
806: controlled by a new ssh_config ObscureKeystrokeTiming keyword.
807: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
808: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
809: Introduce a transport-level ping facility. This adds
810: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
811: implement a ping capability. These messages use numbers in the "local
812: extensions" number space and are advertised using a "ping@openssh.com"
813: ext-info message with a string version number of "0".
1.13 dtucker 814: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
815: allow override of Subsystem directives in sshd Match blocks.
816: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
817: allow forwarding Unix Domain sockets via ssh -W.
818: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
819: add support for configuration tags to ssh(1).
820: This adds a ssh_config(5) "Tag" directive and corresponding
821: "Match tag" predicate that may be used to select blocks of
822: configuration similar to the pf.conf(5) keywords of the same
823: name.
824: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
825: add a "match localnetwork" predicate. This allows matching
826: on the addresses of available network interfaces and may be used to
827: vary the effective client configuration based on network location.
828: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
829: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
830: <a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
831: infrastructure support for KRL
832: extensions. This defines wire formats for optional KRL extensions
833: and implements parsing of the new submessages. No actual extensions
834: are supported at this point.
835: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
836: AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
837: accept two additional %-expansion sequences: %D which expands to
838: the routing domain of the connected session and %C which expands
839: to the addresses and port numbers for the source and destination
840: of the connection.
841: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
842: increase the default work factor (rounds) for the
843: bcrypt KDF used to derive symmetric encryption keys for passphrase
844: protected key files by 50%.
1.1 deraadt 845: </ul>
846: <li>Bugfixes
847: <ul>
1.12 dtucker 848: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
849: fix scp in SFTP mode recursive upload and download of
850: directories that contain symlinks to other directories. In scp mode,
851: the links would be followed, but in SFTP mode they were not.
852: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
853: handle cr+lf (instead of just cr) line endings in
854: sshsig signature files.
855: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
856: interactive mode for ControlPersist sessions if they
857: originally requested a tty.
858: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
859: make PerSourceMaxStartups first-match-wins
860: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
861: limit artificial login delay to a reasonable maximum (5s)
862: and don't delay at all for the "none" authentication mechanism.
1.13 dtucker 863: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
864: Log errors in kex_exchange_identification() with level
1.12 dtucker 865: verbose instead of error to reduce preauth log spam. All of those
866: get logged with a more generic error message by sshpkt_fatal().
867: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
868: correct math for ClientAliveInterval that caused the probes
869: to be sent less frequently than configured.
1.13 dtucker 870: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
871: improve isolation between loaded PKCS#11 modules
872: by running separate ssh-pkcs11-helpers for each loaded provider.
873: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
874: make -f (fork after authentication) work correctly with
875: multiplexed connections, including ControlPersist.
876: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
877: make ConnectTimeout apply to multiplexing sockets and not
878: just to network connections.
879: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
880: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
881: improve defences against invalid PKCS#11
882: modules being loaded by checking that the requested module
883: contains the required symbol before loading it.
884: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
885: fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand
886: appears before it in sshd_config. Since OpenSSH 8.7 the
887: AuthorizedPrincipalsCommand directive was incorrectly ignored in
888: this situation.
889: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
890: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
891: <a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1.16 jsg 892: remove vestigial support for KRL
1.13 dtucker 893: signatures When the KRL format was originally defined, it included
894: support for signing of KRL objects. However, the code to sign KRLs
1.16 jsg 895: and verify KRL signatures was never completed in OpenSSH. This
1.13 dtucker 896: release removes the partially-implemented code to verify KRLs.
897: All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in
898: KRL files.
899: <li>All: fix a number of memory leaks and unreachable/harmless integer
900: overflows.
901: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
902: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
903: don't truncate strings logged from PKCS#11 modules
904: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
905: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
906: better validate CASignatureAlgorithms in
907: ssh_config and sshd_config. Previously this directive would accept
908: certificate algorithm names, but these were unusable in practice as
909: OpenSSH does not support CA chains.
910: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
911: make <code>ssh -Q CASignatureAlgorithms</code> only list signature
912: algorithms that are valid for CA signing. Previous behaviour was
913: to list all signing algorithms, including certificate algorithms.
914: <li><a href="https://man.openbsd.org/ssh-keyscan.1">ssh-keyscan(1)</a>:
915: gracefully handle systems where rlimits or the
916: maximum number of open files is larger than INT_MAX
917: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
918: fix "no comment" not showing on when running
919: <code>ssh-keygen -l</code> on multiple keys where one has a comment
920: and other following keys do not.
921: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>,
1.14 dtucker 922: <a href="https://man.openbsd.org/sftp.1">sftp(1)</a>:
1.13 dtucker 923: adjust ftruncate() logic to handle servers that
924: reorder requests. Previously, if the server reordered requests then
925: the resultant file would be erroneously truncated.
926: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
927: don't incorrectly disable hostname canonicalization when
1.16 jsg 928: CanonicalizeHostname=yes and ProxyJump was explicitly set to
1.13 dtucker 929: "none".
930: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
931: when copying local to remote, check that the source file
932: exists before opening an SFTP connection to the server.

1224: <section id=sourcecode>
1225: <h3>Notes about the source code</h3>
1226: <p>
1227: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1228: This file contains everything you need except for the kernel sources,
1229: which are in a separate archive.
1230: To extract:
1231: <blockquote><pre>
1232: # <kbd>mkdir -p /usr/src</kbd>
1233: # <kbd>cd /usr/src</kbd>
1234: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1235: </pre></blockquote>
1236: <p>
1237: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1238: This file contains all the kernel sources you need to rebuild kernels.
1239: To extract:
1240: <blockquote><pre>
1241: # <kbd>mkdir -p /usr/src/sys</kbd>
1242: # <kbd>cd /usr/src</kbd>
1243: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1244: </pre></blockquote>
1245: <p>
1246: Both of these trees are a regular CVS checkout. Using these trees it
1247: is possible to get a head-start on using the anoncvs servers as
1248: described <a href="anoncvs.html">here</a>.
1249: Using these files
1250: results in a much faster initial CVS update than you could expect from
1251: a fresh checkout of the full OpenBSD source tree.

1258: <p>
1259: A ports tree archive is also provided. To extract:
1260: <blockquote><pre>
1261: # <kbd>cd /usr</kbd>
1262: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1263: </pre></blockquote>
1264: <p>
1265: Go read the <a href="faq/ports/index.html">ports</a> page
1266: if you know nothing about ports
1267: at this point. This text is not a manual of how to use ports.
1268: Rather, it is a set of notes meant to kickstart the user on the
1269: OpenBSD ports system.
1270: <p>
1271: The <i>ports/</i> directory represents a CVS checkout of our ports.
1272: As with our complete source tree, our ports tree is available via
1273: <a href="anoncvs.html">AnonCVS</a>.
1274: So, in order to keep up to date with the -stable branch, you must make
1275: the <i>ports/</i> tree available on a read-write medium and update the tree
1276: with a command like:
1277: <blockquote><pre>
1278: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1279: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1280: </pre></blockquote>
1281: <p>
1282: [Of course, you must replace the server name here with a nearby anoncvs
1283: server.]
1284: <p>
1285: Note that most ports are available as packages on our mirrors. Updated
1286: ports for the 7.4 release will be made available if problems arise.
1287: <p>
1288: If you're interested in seeing a port added, would like to help out, or just
1289: would like to know more, the mailing list
1290: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
