571: non-inheriting CA certificates are now marked as trusted roots. This
572: way it can be ensured that a leaf's delegated resources are properly

592: <li>File modification timestamps of objects retrieved via RRDP are now
593: deterministically set to prepare the on-disk cache for seamless
594: failovers from RRDP to RSYNC.
595: <li>Improved detection of RRDP session desynchronization: a check was

609: the manifestNumber to aid debugging the cause.
610: <li>A check was added to disallow multiple RRDP publish elements for the
611: same file in RRDP snapshots. If this error condition is encountered,
612: the RRDP transfer is failed and the RP falls back to rsync.
613: <li>A compliance check for the proper X.509 Certificate version and CRL
614: version was added.
615: <li>A compliance check was added to ensure CMS Signed Objects contain
616: SignedData, in accordance to RFC 6488 section 3 checklist item 1a.
617: <li>Compliance checks were added for the version, KeyUsage, and
618: ExtendedKeyUsage of EE certificates in Manifest, TAK, and GBR Signed

733: assembly.
1.1 deraadt 734: </ul>
735: <li>Compatibility changes
736: <ul>
1.7 tb 737: <li>Added a workaround for a poorly thought-out change in OpenSSL 3 that
738: broke privilege separation support in libtls.
739: <li>Moved libtls from ECDSA_METHOD to EC_KEY_METHOD.

1.8 tb 752: openssl(1) nseq command.
1.7 tb 753: <li>ENGINE support was removed and OPENSSL_NO_ENGINE is set. In spite
754: of this, some stub functions are provided to avoid patching some
755: applications that do not honor OPENSSL_NO_ENGINE.
756: <li>The POLICY_TREE and its related structures and API were removed.
757: <li>In X509_VERIFY_PARAM_inherit() copy hostflags independently of the
758: host list.
759: <li>Made CRYPTO_get_ex_new_index() not return 0 to allow applications

761: each other.
762: <li>X509_NAME_get_text_by_{NID,OBJ}() now only succeed if they contain
763: valid UTF-8 without embedded NUL.
764: <li>The explicitText user notice uses UTF8String instead of VisibleString

825: on invalidated file descriptors.
826: <li>Allow IP addresses to be specified in a URI.
827: <li>Fixed a copy-paste error in ASN1_TIME_compare() that could lead
828: to two UTCTimes or two GeneralizedTimes incorrectly being compared
829: as equal.
830: </ul>
831: <li>Documentation improvements

1.1 deraadt 850: <ul>
1.12 dtucker 851: <li>Potentially incompatible changes
1.1 deraadt 852: <ul>
1.12 dtucker 853: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
854: generate Ed25519 keys by default. Ed25519 public keys
855: are very convenient due to their small size. Ed25519 keys are
856: specified in RFC 8709 and OpenSSH has supported them since version 6.5
857: (January 2014).
858: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
859: the Subsystem directive now accurately preserves quoting of
860: subsystem commands and arguments. This may change behaviour for exotic
861: configurations, but the most common subsystem configuration
862: (sftp-server) is unlikely to be affected.
1.13 dtucker 863: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
864: PKCS#11 modules must now be specified by their full
865: paths. Previously dlopen(3) could search for them in system
866: library directories.
1.1 deraadt 867: </ul>
1.12 dtucker 868: <li>New features
1.1 deraadt 869: <ul>
1.12 dtucker 870: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
871: add keystroke timing obfuscation to the client. This attempts
872: to hide inter-keystroke timings by sending interactive traffic at
873: fixed intervals (default: every 20ms) when there is only a small
874: amount of data being sent. It also sends fake "chaff" keystrokes for
875: a random interval after the last real keystroke. These are
876: controlled by a new ssh_config ObscureKeystrokeTiming keyword.
877: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
878: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
879: Introduce a transport-level ping facility. This adds
880: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
881: implement a ping capability. These messages use numbers in the "local
882: extensions" number space and are advertised using a "ping@openssh.com"
883: ext-info message with a string version number of "0".
1.13 dtucker 884: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
885: allow override of Subsystem directives in sshd Match blocks.
886: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
887: allow forwarding Unix Domain sockets via ssh -W.
888: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
889: add support for configuration tags to ssh(1).
890: This adds a ssh_config(5) "Tag" directive and corresponding
891: "Match tag" predicate that may be used to select blocks of
892: configuration similar to the pf.conf(5) keywords of the same
893: name.
894: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
895: add a "match localnetwork" predicate. This allows matching
896: on the addresses of available network interfaces and may be used to
897: vary the effective client configuration based on network location.
898: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
899: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
900: <a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
901: infrastructure support for KRL
902: extensions. This defines wire formats for optional KRL extensions
903: and implements parsing of the new submessages. No actual extensions
904: are supported at this point.
905: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
906: AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
907: accept two additional %-expansion sequences: %D which expands to
908: the routing domain of the connected session and %C which expands
909: to the addresses and port numbers for the source and destination
910: of the connection.
911: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
912: increase the default work factor (rounds) for the
913: bcrypt KDF used to derive symmetric encryption keys for passphrase
914: protected key files by 50%.
1.1 deraadt 915: </ul>
916: <li>Bugfixes
917: <ul>
1.12 dtucker 918: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
919: fix scp in SFTP mode recursive upload and download of
920: directories that contain symlinks to other directories. In scp mode,
921: the links would be followed, but in SFTP mode they were not.
922: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
923: handle cr+lf (instead of just cr) line endings in
924: sshsig signature files.
925: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
926: interactive mode for ControlPersist sessions if they
927: originally requested a tty.
928: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
929: make PerSourceMaxStartups first-match-wins
930: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
931: limit artificial login delay to a reasonable maximum (5s)
932: and don't delay at all for the "none" authentication mechanism.
1.13 dtucker 933: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
934: Log errors in kex_exchange_identification() with level
1.12 dtucker 935: verbose instead of error to reduce preauth log spam. All of those
936: get logged with a more generic error message by sshpkt_fatal().
937: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
938: correct math for ClientAliveInterval that caused the probes
939: to be sent less frequently than configured.
1.13 dtucker 940: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
941: improve isolation between loaded PKCS#11 modules
942: by running separate ssh-pkcs11-helpers for each loaded provider.
943: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
944: make -f (fork after authentication) work correctly with
945: multiplexed connections, including ControlPersist.
946: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
947: make ConnectTimeout apply to multiplexing sockets and not
948: just to network connections.
949: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
950: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
951: improve defences against invalid PKCS#11
952: modules being loaded by checking that the requested module
953: contains the required symbol before loading it.
954: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
955: fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand
956: appears before it in sshd_config. Since OpenSSH 8.7 the
957: AuthorizedPrincipalsCommand directive was incorrectly ignored in
958: this situation.
959: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
960: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
961: <a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1.16 jsg 962: remove vestigial support for KRL
1.13 dtucker 963: signatures When the KRL format was originally defined, it included
964: support for signing of KRL objects. However, the code to sign KRLs
1.16 jsg 965: and verify KRL signatures was never completed in OpenSSH. This
1.13 dtucker 966: release removes the partially-implemented code to verify KRLs.
967: All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in
968: KRL files.
969: <li>All: fix a number of memory leaks and unreachable/harmless integer
970: overflows.
971: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
972: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
973: don't truncate strings logged from PKCS#11 modules
974: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
975: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
976: better validate CASignatureAlgorithms in
977: ssh_config and sshd_config. Previously this directive would accept
978: certificate algorithm names, but these were unusable in practice as
979: OpenSSH does not support CA chains.
980: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
981: make <code>ssh -Q CASignatureAlgorithms</code> only list signature
982: algorithms that are valid for CA signing. Previous behaviour was
983: to list all signing algorithms, including certificate algorithms.
984: <li><a href="https://man.openbsd.org/ssh-keyscan.1">ssh-keyscan(1)</a>:
985: gracefully handle systems where rlimits or the
986: maximum number of open files is larger than INT_MAX
987: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
988: fix "no comment" not showing on when running
989: <code>ssh-keygen -l</code> on multiple keys where one has a comment
990: and other following keys do not.
991: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>,
1.14 dtucker 992: <a href="https://man.openbsd.org/sftp.1">sftp(1)</a>:
1.13 dtucker 993: adjust ftruncate() logic to handle servers that
994: reorder requests. Previously, if the server reordered requests then
995: the resultant file would be erroneously truncated.
996: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
997: don't incorrectly disable hostname canonicalization when
1.16 jsg 998: CanonicalizeHostname=yes and ProxyJump was explicitly set to
1.13 dtucker 999: "none".
1000: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:

1287: <p>
1.3 jsg 1288: If you already have an OpenBSD 7.3 system, and do not want to reinstall,
1.1 deraadt 1289: upgrade instructions and advice can be found in the

1295: <section id=sourcecode>
1296: <h3>Notes about the source code</h3>
1297: <p>
1298: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1299: This file contains everything you need except for the kernel sources,
1300: which are in a separate archive.
1301: To extract:
1302: <blockquote><pre>
1303: # <kbd>mkdir -p /usr/src</kbd>
1304: # <kbd>cd /usr/src</kbd>
1305: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1306: </pre></blockquote>
1307: <p>
1308: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1309: This file contains all the kernel sources you need to rebuild kernels.
1310: To extract:
1311: <blockquote><pre>
1312: # <kbd>mkdir -p /usr/src/sys</kbd>
1313: # <kbd>cd /usr/src</kbd>
1314: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1315: </pre></blockquote>
1316: <p>
1317: Both of these trees are a regular CVS checkout. Using these trees it
1318: is possible to get a head-start on using the anoncvs servers as
1319: described <a href="anoncvs.html">here</a>.
1320: Using these files
1321: results in a much faster initial CVS update than you could expect from
1322: a fresh checkout of the full OpenBSD source tree.

1328: <h3>Ports Tree</h3>
1329: <p>
1330: A ports tree archive is also provided. To extract:
1331: <blockquote><pre>
1332: # <kbd>cd /usr</kbd>
1333: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1334: </pre></blockquote>
1335: <p>
1336: Go read the <a href="faq/ports/index.html">ports</a> page
1337: if you know nothing about ports
1338: at this point. This text is not a manual of how to use ports.
1339: Rather, it is a set of notes meant to kickstart the user on the
1340: OpenBSD ports system.
1341: <p>
1342: The <i>ports/</i> directory represents a CVS checkout of our ports.
1343: As with our complete source tree, our ports tree is available via
1344: <a href="anoncvs.html">AnonCVS</a>.
1345: So, in order to keep up to date with the -stable branch, you must make
1346: the <i>ports/</i> tree available on a read-write medium and update the tree
1347: with a command like:
1348: <blockquote><pre>
1349: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1350: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1351: </pre></blockquote>
1352: <p>
1353: [Of course, you must replace the server name here with a nearby anoncvs
1354: server.]
1355: <p>
1356: Note that most ports are available as packages on our mirrors. Updated
1357: ports for the 7.4 release will be made available if problems arise.
1358: <p>
1359: If you're interested in seeing a port added, would like to help out, or just
1360: would like to know more, the mailing list
1361: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
