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

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554: withdrawn, and published again.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

562: Object is missing.
563: <li>Warnings about unrecoverable message digest mismatches now include
564: the manifestNumber to aid debugging the cause.
565: <li>A check was added to disallow multiple RRDP publish elements for the
566: same file in RRDP snapshots. If this error condition is encountered,
567: the RRDP transfer is failed and the RP falls back to rsync.
568: <li>A compliance check for the proper X.509 Certificate version and CRL
569: version was added.
570: <li>A compliance check was added to ensure CMS Signed Objects contain
571: SignedData, in accordance to RFC 6488 section 3 checklist item 1a.
572: <li>Compliance checks were added for the version, KeyUsage, and
573: ExtendedKeyUsage of EE certificates in Manifest, TAK, and GBR Signed
574: Objects.
575: <li>A CMS signing-time value being after the X.509 notAfter timestamp
576: was downgraded from an error to a warning.
577: <li>A bug was fixed in the handling of CA certificates which inherit IP
578: resources.
579: <li>A compliance check was added to ensure the X.509 Subject only
580: contains commonName and optionally serialNumber.
581: <li>A compliance check was added to ensure the CMS SignedData and
582: SignerInfo versions to be 3.
583: <li>Fisher-Yates shuffle the order in which Manifest entries are
584: processed. Previously, work items were enqueued in the order the CA

1.1 deraadt 796: <ul>
1.12 dtucker 797: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
798: generate Ed25519 keys by default. Ed25519 public keys
799: are very convenient due to their small size. Ed25519 keys are
800: specified in RFC 8709 and OpenSSH has supported them since version 6.5
801: (January 2014).
802: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
803: the Subsystem directive now accurately preserves quoting of
804: subsystem commands and arguments. This may change behaviour for exotic
805: configurations, but the most common subsystem configuration
806: (sftp-server) is unlikely to be affected.
1.13 dtucker 807: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
808: PKCS#11 modules must now be specified by their full
809: paths. Previously dlopen(3) could search for them in system
810: library directories.

1.12 dtucker 812: <li>New features
1.1 deraadt 813: <ul>
1.12 dtucker 814: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
815: add keystroke timing obfuscation to the client. This attempts
816: to hide inter-keystroke timings by sending interactive traffic at
817: fixed intervals (default: every 20ms) when there is only a small
818: amount of data being sent. It also sends fake "chaff" keystrokes for
819: a random interval after the last real keystroke. These are
820: controlled by a new ssh_config ObscureKeystrokeTiming keyword.
821: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
822: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
823: Introduce a transport-level ping facility. This adds
824: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
825: implement a ping capability. These messages use numbers in the "local
826: extensions" number space and are advertised using a "ping@openssh.com"
827: ext-info message with a string version number of "0".
1.13 dtucker 828: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
829: allow override of Subsystem directives in sshd Match blocks.
830: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
831: allow forwarding Unix Domain sockets via ssh -W.
832: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
833: add support for configuration tags to ssh(1).
834: This adds a ssh_config(5) "Tag" directive and corresponding
835: "Match tag" predicate that may be used to select blocks of
836: configuration similar to the pf.conf(5) keywords of the same
837: name.
838: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
839: add a "match localnetwork" predicate. This allows matching
840: on the addresses of available network interfaces and may be used to
841: vary the effective client configuration based on network location.
842: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
843: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
844: <a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
845: infrastructure support for KRL
846: extensions. This defines wire formats for optional KRL extensions
847: and implements parsing of the new submessages. No actual extensions
848: are supported at this point.
849: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
850: AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
851: accept two additional %-expansion sequences: %D which expands to
852: the routing domain of the connected session and %C which expands
853: to the addresses and port numbers for the source and destination
854: of the connection.
855: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
856: increase the default work factor (rounds) for the
857: bcrypt KDF used to derive symmetric encryption keys for passphrase
858: protected key files by 50%.
1.1 deraadt 859: </ul>
860: <li>Bugfixes
861: <ul>
1.12 dtucker 862: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
863: fix scp in SFTP mode recursive upload and download of
864: directories that contain symlinks to other directories. In scp mode,
865: the links would be followed, but in SFTP mode they were not.
866: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
867: handle cr+lf (instead of just cr) line endings in
868: sshsig signature files.
869: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
870: interactive mode for ControlPersist sessions if they
871: originally requested a tty.
872: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
873: make PerSourceMaxStartups first-match-wins
874: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
875: limit artificial login delay to a reasonable maximum (5s)
876: and don't delay at all for the "none" authentication mechanism.
1.13 dtucker 877: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
878: Log errors in kex_exchange_identification() with level
1.12 dtucker 879: verbose instead of error to reduce preauth log spam. All of those
880: get logged with a more generic error message by sshpkt_fatal().
881: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
882: correct math for ClientAliveInterval that caused the probes
883: to be sent less frequently than configured.
1.13 dtucker 884: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
885: improve isolation between loaded PKCS#11 modules
886: by running separate ssh-pkcs11-helpers for each loaded provider.
887: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
888: make -f (fork after authentication) work correctly with
889: multiplexed connections, including ControlPersist.
890: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
891: make ConnectTimeout apply to multiplexing sockets and not
892: just to network connections.
893: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
894: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
895: improve defences against invalid PKCS#11
896: modules being loaded by checking that the requested module
897: contains the required symbol before loading it.
898: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
899: fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand
900: appears before it in sshd_config. Since OpenSSH 8.7 the
901: AuthorizedPrincipalsCommand directive was incorrectly ignored in
902: this situation.
903: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
904: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
905: <a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1.16 jsg 906: remove vestigial support for KRL
1.13 dtucker 907: signatures When the KRL format was originally defined, it included
908: support for signing of KRL objects. However, the code to sign KRLs
1.16 jsg 909: and verify KRL signatures was never completed in OpenSSH. This
1.13 dtucker 910: release removes the partially-implemented code to verify KRLs.
911: All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in
912: KRL files.
913: <li>All: fix a number of memory leaks and unreachable/harmless integer
914: overflows.
915: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
916: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
917: don't truncate strings logged from PKCS#11 modules
918: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
919: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
920: better validate CASignatureAlgorithms in
921: ssh_config and sshd_config. Previously this directive would accept
922: certificate algorithm names, but these were unusable in practice as
923: OpenSSH does not support CA chains.
924: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
925: make <code>ssh -Q CASignatureAlgorithms</code> only list signature
926: algorithms that are valid for CA signing. Previous behaviour was
927: to list all signing algorithms, including certificate algorithms.
928: <li><a href="https://man.openbsd.org/ssh-keyscan.1">ssh-keyscan(1)</a>:
929: gracefully handle systems where rlimits or the
930: maximum number of open files is larger than INT_MAX
931: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
932: fix "no comment" not showing on when running
933: <code>ssh-keygen -l</code> on multiple keys where one has a comment
934: and other following keys do not.
935: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>,
1.14 dtucker 936: <a href="https://man.openbsd.org/sftp.1">sftp(1)</a>:
1.13 dtucker 937: adjust ftruncate() logic to handle servers that
938: reorder requests. Previously, if the server reordered requests then
939: the resultant file would be erroneously truncated.
940: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
941: don't incorrectly disable hostname canonicalization when
1.16 jsg 942: CanonicalizeHostname=yes and ProxyJump was explicitly set to
1.13 dtucker 943: "none".
944: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
945: when copying local to remote, check that the source file

1239: <h3>Notes about the source code</h3>
1240: <p>
1241: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1242: This file contains everything you need except for the kernel sources,
1243: which are in a separate archive.
1244: To extract:
1245: <blockquote><pre>
1246: # <kbd>mkdir -p /usr/src</kbd>
1247: # <kbd>cd /usr/src</kbd>
1248: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1249: </pre></blockquote>
1250: <p>
1251: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1252: This file contains all the kernel sources you need to rebuild kernels.
1253: To extract:
1254: <blockquote><pre>
1255: # <kbd>mkdir -p /usr/src/sys</kbd>
1256: # <kbd>cd /usr/src</kbd>
1257: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1258: </pre></blockquote>
1259: <p>
1260: Both of these trees are a regular CVS checkout. Using these trees it
1261: is possible to get a head-start on using the anoncvs servers as
1262: described <a href="anoncvs.html">here</a>.
1263: Using these files
1264: results in a much faster initial CVS update than you could expect from
1265: a fresh checkout of the full OpenBSD source tree.

1276: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1277: </pre></blockquote>
1278: <p>
1279: Go read the <a href="faq/ports/index.html">ports</a> page
1280: if you know nothing about ports
1281: at this point. This text is not a manual of how to use ports.
1282: Rather, it is a set of notes meant to kickstart the user on the
1283: OpenBSD ports system.
1284: <p>
1285: The <i>ports/</i> directory represents a CVS checkout of our ports.
1286: As with our complete source tree, our ports tree is available via
1287: <a href="anoncvs.html">AnonCVS</a>.
1288: So, in order to keep up to date with the -stable branch, you must make
1289: the <i>ports/</i> tree available on a read-write medium and update the tree
1290: with a command like:
1291: <blockquote><pre>
1292: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1293: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1294: </pre></blockquote>
1295: <p>
1296: [Of course, you must replace the server name here with a nearby anoncvs
1297: server.]
1298: <p>
1299: Note that most ports are available as packages on our mirrors. Updated
1300: ports for the 7.4 release will be made available if problems arise.
1301: <p>
1302: If you're interested in seeing a port added, would like to help out, or just
1303: would like to know more, the mailing list
1304: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
