623: the manifestNumber to aid debugging the cause.
624: <li>A check was added to disallow multiple RRDP publish elements for the
625: same file in RRDP snapshots. If this error condition is encountered,
626: the RRDP transfer is failed and the RP falls back to rsync.
627: <li>A compliance check for the proper X.509 Certificate version and CRL
628: version was added.
629: <li>A compliance check was added to ensure CMS Signed Objects contain
630: SignedData, in accordance to RFC 6488 section 3 checklist item 1a.
631: <li>Compliance checks were added for the version, KeyUsage, and
632: ExtendedKeyUsage of EE certificates in Manifest, TAK, and GBR Signed

720: <li>Applications bundled as part of the LibreSSL package internally,
721: nc(1) and openssl(1), now are linked statically if static libraries
722: are built.
723: <li>Internal compatibility function symbols are no longer exported from
724: libcrypto. Instead, the libcompat library is linked to libcrypto,
725: libssl, and libtls separately. This increases size a little, but
726: ensures that the libraries are not exporting symbols to programs
727: unintentionally.
728: <li>Selective removal of CET implementation on platforms where it is
729: not supported (macOS).
730: <li>Integrated four more tests.
731: <li>Added Windows ARM64 architecture to tested platforms.
732: <li>Removed Solaris 10 support, fixed Solaris 11.
733: <li>libtls no longer links statically to libcrypto / libssl unless
734: <code>--enable-libtls-only</code> is specified at configure time.
735: <li>Improved Windows compatibility library, namely handling of files vs
736: sockets, correcting an exception when operating on a closed socket.
737: <li>CMake builds no longer hardcode <code>-O2</code> into the compiler flags,
738: instead using flags from the CMake build type instead.
739: <li>Set the CMake default build type to <code>Release</code>. This can be overridden
740: during configuration.
741: <li>Fixed broken ASM support with MinGW builds.

1.7 tb 745: <li>Added support for truncated SHA-2 and for SHA-3.
746: <li>The BPSW primality test performs additional Miller-Rabin rounds
747: with random bases to reduce the likelihood of composites passing.
748: <li>Allow testing of ciphers and digests using badly aligned buffers
749: in openssl speed using -unalign.

758: broke privilege separation support in libtls.
759: <li>Moved libtls from ECDSA_METHOD to EC_KEY_METHOD.
760: <li>Removed GF2m support: BIGNUM no longer supports binary extension
761: field arithmetic and all binary elliptic builtin curves were removed.
762: <li>Removed dangerous, "fast" NIST prime and elliptic curve implementations.
763: In particular, EC_GFp_nist_method() is no longer available.
764: <li>Removed most public symbols that were deprecated in OpenSSL 0.9.8.
765: <li>Removed the public X9.31 API (RSA_X931_PADDING is still available).
766: <li>Removed Cipher Text Stealing mode.
767: <li>Removed ENGINE support, including ECDH_METHOD and ECDSA_METHOD.
768: <li>Removed COMP, DSO, dynamic loading of conf modules and support for
769: custom ex_data and error stacks.
770: <li>Removed proxy certificate (RFC 3820) support.
771: <li>Removed SXNET and NETSCAPE_CERT_SEQUENCE support including the
1.8 tb 772: openssl(1) nseq command.
1.7 tb 773: <li>ENGINE support was removed and OPENSSL_NO_ENGINE is set. In spite
774: of this, some stub functions are provided to avoid patching some
775: applications that do not honor OPENSSL_NO_ENGINE.
776: <li>The POLICY_TREE and its related structures and API were removed.
777: <li>In X509_VERIFY_PARAM_inherit() copy hostflags independently of the
778: host list.
779: <li>Made CRYPTO_get_ex_new_index() not return 0 to allow applications
780: to use *_{get,set}_app_data() and *_{get,set}_ex_data() alongside
781: each other.
782: <li>X509_NAME_get_text_by_{NID,OBJ}() now only succeed if they contain
783: valid UTF-8 without embedded NUL.
784: <li>The explicitText user notice uses UTF8String instead of VisibleString
785: to reduce the risk of emitting certificates with invalid DER-encoding.
786: <li>Initial fixes for RSA-PSS support to make the TLSv1.3 stack more
787: compliant with RFC 8446.
788: <li>Fixed EVP_CIPHER_CTX_iv_length() to return what was set with
789: EVP_CTRL_AEAD_SET_IVLEN or one of its aliases.

797: to replace the old exponential time code.
798: <li>Converted more of libcrypto to use CBB/CBS.
799: <li>Started cleaning up and rewriting SHA internals.
800: <li>Reduced the dependency of hash implementations on many layers of

1.1 deraadt 872: <ul>
1.12 dtucker 873: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
874: generate Ed25519 keys by default. Ed25519 public keys
875: are very convenient due to their small size. Ed25519 keys are
876: specified in RFC 8709 and OpenSSH has supported them since version 6.5
877: (January 2014).
878: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
879: the Subsystem directive now accurately preserves quoting of
880: subsystem commands and arguments. This may change behaviour for exotic
881: configurations, but the most common subsystem configuration
882: (sftp-server) is unlikely to be affected.
1.13 dtucker 883: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:

1.1 deraadt 889: <ul>
1.12 dtucker 890: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
891: add keystroke timing obfuscation to the client. This attempts
892: to hide inter-keystroke timings by sending interactive traffic at
893: fixed intervals (default: every 20ms) when there is only a small
894: amount of data being sent. It also sends fake "chaff" keystrokes for
895: a random interval after the last real keystroke. These are
896: controlled by a new ssh_config ObscureKeystrokeTiming keyword.
897: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
898: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
899: Introduce a transport-level ping facility. This adds
900: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
901: implement a ping capability. These messages use numbers in the "local
902: extensions" number space and are advertised using a "ping@openssh.com"
903: ext-info message with a string version number of "0".
1.13 dtucker 904: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
905: allow override of Subsystem directives in sshd Match blocks.
906: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
907: allow forwarding Unix Domain sockets via ssh -W.
908: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
909: add support for configuration tags to ssh(1).
910: This adds a ssh_config(5) "Tag" directive and corresponding
911: "Match tag" predicate that may be used to select blocks of
912: configuration similar to the pf.conf(5) keywords of the same
913: name.
914: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
915: add a "match localnetwork" predicate. This allows matching
916: on the addresses of available network interfaces and may be used to
917: vary the effective client configuration based on network location.

921: infrastructure support for KRL
922: extensions. This defines wire formats for optional KRL extensions
923: and implements parsing of the new submessages. No actual extensions
924: are supported at this point.
925: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
926: AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
927: accept two additional %-expansion sequences: %D which expands to
928: the routing domain of the connected session and %C which expands
929: to the addresses and port numbers for the source and destination
930: of the connection.
931: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:

939: fix scp in SFTP mode recursive upload and download of
940: directories that contain symlinks to other directories. In scp mode,
941: the links would be followed, but in SFTP mode they were not.
942: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
943: handle cr+lf (instead of just cr) line endings in
944: sshsig signature files.
945: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
946: interactive mode for ControlPersist sessions if they
947: originally requested a tty.

949: make PerSourceMaxStartups first-match-wins
950: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
951: limit artificial login delay to a reasonable maximum (5s)
952: and don't delay at all for the "none" authentication mechanism.
1.13 dtucker 953: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
954: Log errors in kex_exchange_identification() with level
1.12 dtucker 955: verbose instead of error to reduce preauth log spam. All of those
956: get logged with a more generic error message by sshpkt_fatal().
957: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
958: correct math for ClientAliveInterval that caused the probes
959: to be sent less frequently than configured.
1.13 dtucker 960: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:

973: contains the required symbol before loading it.
974: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
975: fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand
976: appears before it in sshd_config. Since OpenSSH 8.7 the

978: this situation.

1.16 jsg 982: remove vestigial support for KRL
1.13 dtucker 983: signatures When the KRL format was originally defined, it included
984: support for signing of KRL objects. However, the code to sign KRLs
1.16 jsg 985: and verify KRL signatures was never completed in OpenSSH. This
1.13 dtucker 986: release removes the partially-implemented code to verify KRLs.
987: All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in
988: KRL files.
989: <li>All: fix a number of memory leaks and unreachable/harmless integer
990: overflows.

995: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
996: better validate CASignatureAlgorithms in
997: ssh_config and sshd_config. Previously this directive would accept
998: certificate algorithm names, but these were unusable in practice as
999: OpenSSH does not support CA chains.
1000: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1001: make <code>ssh -Q CASignatureAlgorithms</code> only list signature
1002: algorithms that are valid for CA signing. Previous behaviour was
1003: to list all signing algorithms, including certificate algorithms.
1004: <li><a href="https://man.openbsd.org/ssh-keyscan.1">ssh-keyscan(1)</a>:
1005: gracefully handle systems where rlimits or the

1015: the resultant file would be erroneously truncated.
1016: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:

1316: <h3>Notes about the source code</h3>
1317: <p>
1318: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1319: This file contains everything you need except for the kernel sources,
1320: which are in a separate archive.
1321: To extract:
1322: <blockquote><pre>
1323: # <kbd>mkdir -p /usr/src</kbd>
1324: # <kbd>cd /usr/src</kbd>
1325: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1326: </pre></blockquote>
1327: <p>
1328: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1329: This file contains all the kernel sources you need to rebuild kernels.
1330: To extract:
1331: <blockquote><pre>
1332: # <kbd>mkdir -p /usr/src/sys</kbd>
1333: # <kbd>cd /usr/src</kbd>
1334: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1335: </pre></blockquote>
1336: <p>
1337: Both of these trees are a regular CVS checkout. Using these trees it
1338: is possible to get a head-start on using the anoncvs servers as
1339: described <a href="anoncvs.html">here</a>.
1340: Using these files
1341: results in a much faster initial CVS update than you could expect from
1342: a fresh checkout of the full OpenBSD source tree.

1349: <p>
1350: A ports tree archive is also provided. To extract:
1351: <blockquote><pre>
1352: # <kbd>cd /usr</kbd>
1353: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1354: </pre></blockquote>
1355: <p>
1356: Go read the <a href="faq/ports/index.html">ports</a> page
1357: if you know nothing about ports
1358: at this point. This text is not a manual of how to use ports.
1359: Rather, it is a set of notes meant to kickstart the user on the
1360: OpenBSD ports system.
1361: <p>
1362: The <i>ports/</i> directory represents a CVS checkout of our ports.
1363: As with our complete source tree, our ports tree is available via
1364: <a href="anoncvs.html">AnonCVS</a>.
1365: So, in order to keep up to date with the -stable branch, you must make
1366: the <i>ports/</i> tree available on a read-write medium and update the tree
1367: with a command like:
1368: <blockquote><pre>
1369: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1370: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1371: </pre></blockquote>
1372: <p>
1373: [Of course, you must replace the server name here with a nearby anoncvs
1374: server.]
1375: <p>
1376: Note that most ports are available as packages on our mirrors. Updated
1377: ports for the 7.4 release will be made available if problems arise.
1378: <p>
1379: If you're interested in seeing a port added, would like to help out, or just
1380: would like to know more, the mailing list
1381: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
