78:
79: <li>New/extended platforms:
80: <ul>
1.11 benno 81: <li>On arm64, implement branch target protection using the branch
82: target identification feature introduced in Armv8.5. This provides
83: "head-CFI" to complement the "tail-CFI" provided by retguard, and is
84: supported on Apple M2.
1.1 deraadt 85: </ul>
86:
87: <li>Various kernel improvements:

96: floppy disk devices as floppy disks.
1.44 schwarze 97: <li>In <a href="https://man.openbsd.org/wscons.4">wscons(4)</a>,
98: catch up with box drawing characters which have
1.35 benno 99: been standardized in unicode after the original wscons code was
100: written and chose placeholder values.
1.81 benno 101: <li>In <a href="https://man.openbsd.org/wscons.4">wscons(4)</a>,
102: make sure we do not increase the escape sequence argument count beyond

116: in the idle loop and for suspend, resulting in power savings.
1.81 benno 117: <li>Update AMD CPU microcode if a newer patch is available.
118: <li>Enable a workaround for the 'Zenbleed' AMD CPU bug.
119: <li>Report speculation control bits in dmesg cpu lines.
120: <li>To give the primary CPU an opportunity to perform clock interrupt
121: preparation in a machine-independent manner we need to separate the
122: "initialization" parts of cpu_initclocks() from the "start the clock
123: interrupt" parts. Separate cpu_initclocks() from cpu_startclock().
124: <li>Fix a problem where CPU time accounting and RLIMIT_CPU was
125: unreliable on idle systems.
126: <li>Improve the output of the "show proc" command of the kernel
127: debugger <a href="https://man.openbsd.org/ddb.4">ddb(4)</a> and show
128: both the PID and TID of the proc.

814: encapsulate traffic before being sent to the peer on the SA. When
815: traffic is received from a peer using an interface SA, the specified
816: interface is looked up and the packet is handed to it so it looks

1063: <ul>
1064: <li>Disabled TLSv1.0 and TLSv1.1 in libssl so that they may no longer
1065: be selected for use.
1066: <li>BN_is_prime{,_fasttest}_ex() refuse to check numbers larger than
1067: 32 kbits for primality. This mitigates various DoS vectors.
1068: <li>Restricted the RFC 3779 code to IPv4 and IPv6. It was not written
1069: to be able to deal with anything else.
1070: </ul>
1071: <li>Portable changes
1072: <ul>
1073: <li>Extended the endian.h compat header with hto* and *toh macros.

1079: <li>Internal compatibility function symbols are no longer exported from
1080: libcrypto. Instead, the libcompat library is linked to libcrypto,
1081: libssl, and libtls separately. This increases size a little, but
1082: ensures that the libraries are not exporting symbols to programs
1083: unintentionally.
1084: <li>Selective removal of CET implementation on platforms where it is
1085: not supported (macOS).
1086: <li>Integrated four more tests.
1087: <li>Added Windows ARM64 architecture to tested platforms.
1088: <li>Removed Solaris 10 support, fixed Solaris 11.
1089: <li>libtls no longer links statically to libcrypto / libssl unless
1090: <code>--enable-libtls-only</code> is specified at configure time.
1091: <li>Improved Windows compatibility library, namely handling of files vs
1092: sockets, correcting an exception when operating on a closed socket.
1093: <li>CMake builds no longer hardcode <code>-O2</code> into the compiler flags,
1094: instead using flags from the CMake build type instead.
1095: <li>Set the CMake default build type to <code>Release</code>. This can be overridden
1096: during configuration.

1123: <li>Removed ENGINE support, including ECDH_METHOD and ECDSA_METHOD.
1124: <li>Removed COMP, DSO, dynamic loading of conf modules and support for
1125: custom ex_data and error stacks.
1126: <li>Removed proxy certificate (RFC 3820) support.

1131: applications that do not honor OPENSSL_NO_ENGINE.
1132: <li>The POLICY_TREE and its related structures and API were removed.
1133: <li>In X509_VERIFY_PARAM_inherit() copy hostflags independently of the
1134: host list.
1135: <li>Made CRYPTO_get_ex_new_index() not return 0 to allow applications
1136: to use *_{get,set}_app_data() and *_{get,set}_ex_data() alongside
1137: each other.
1138: <li>X509_NAME_get_text_by_{NID,OBJ}() now only succeed if they contain
1139: valid UTF-8 without embedded NUL.
1140: <li>The explicitText user notice uses UTF8String instead of VisibleString
1141: to reduce the risk of emitting certificates with invalid DER-encoding.
1142: <li>Initial fixes for RSA-PSS support to make the TLSv1.3 stack more
1143: compliant with RFC 8446.
1144: <li>Fixed EVP_CIPHER_CTX_iv_length() to return what was set with

1247: add keystroke timing obfuscation to the client. This attempts
1248: to hide inter-keystroke timings by sending interactive traffic at
1249: fixed intervals (default: every 20ms) when there is only a small
1250: amount of data being sent. It also sends fake "chaff" keystrokes for

1253: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
1254: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1255: Introduce a transport-level ping facility. This adds
1256: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
1257: implement a ping capability. These messages use numbers in the "local
1258: extensions" number space and are advertised using a "ping@openssh.com"

1264: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1265: add support for configuration tags to ssh(1).
1266: This adds a ssh_config(5) "Tag" directive and corresponding

1673: <p>
1674: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1675: This file contains everything you need except for the kernel sources,
1676: which are in a separate archive.
1677: To extract:
1678: <blockquote><pre>
1679: # <kbd>mkdir -p /usr/src</kbd>
1680: # <kbd>cd /usr/src</kbd>
1681: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1682: </pre></blockquote>
1683: <p>
1684: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1685: This file contains all the kernel sources you need to rebuild kernels.
1686: To extract:
1687: <blockquote><pre>
1688: # <kbd>mkdir -p /usr/src/sys</kbd>
1689: # <kbd>cd /usr/src</kbd>
1690: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1691: </pre></blockquote>
1692: <p>
1693: Both of these trees are a regular CVS checkout. Using these trees it
1694: is possible to get a head-start on using the anoncvs servers as
1695: described <a href="anoncvs.html">here</a>.
1696: Using these files
1697: results in a much faster initial CVS update than you could expect from
1698: a fresh checkout of the full OpenBSD source tree.

1712: Go read the <a href="faq/ports/index.html">ports</a> page
1713: if you know nothing about ports
1714: at this point. This text is not a manual of how to use ports.
1715: Rather, it is a set of notes meant to kickstart the user on the
1716: OpenBSD ports system.
1717: <p>
1718: The <i>ports/</i> directory represents a CVS checkout of our ports.
1719: As with our complete source tree, our ports tree is available via
1720: <a href="anoncvs.html">AnonCVS</a>.
1721: So, in order to keep up to date with the -stable branch, you must make
1722: the <i>ports/</i> tree available on a read-write medium and update the tree
1723: with a command like:
1724: <blockquote><pre>
1725: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1726: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1727: </pre></blockquote>
1728: <p>
1729: [Of course, you must replace the server name here with a nearby anoncvs
1730: server.]
1731: <p>
1732: Note that most ports are available as packages on our mirrors. Updated
1733: ports for the 7.4 release will be made available if problems arise.
1734: <p>
1735: If you're interested in seeing a port added, would like to help out, or just
1736: would like to know more, the mailing list
1737: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
