809: encapsulate traffic before being sent to the peer on the SA. When
810: traffic is received from a peer using an interface SA, the specified

1054: <ul>
1.11 benno 1055: <li>For passthrough, don't write to clients attached to different sessions.
1056: <li>Add a format to show if there are unseen changes while in a mode.
1.50 benno 1057: <li>Discard mouse sequences that have the right form but actually
1058: are invalid.
1059: <li>Invalidate cached tty state after changing features since they may
1060: change what the terminal can do and need mouse sequences or similar to
1061: be sent again.
1.51 benno 1062: <li>Add options to change the confirm key and default behaviour of
1063: confirm-before.
1.81 benno 1064: <li>Add iked support for route based sec(4) tunnels.

1.7 tb 1072: <li>LibreSSL version 3.8.2
1.1 deraadt 1073: <ul>
1.7 tb 1074: <li>Security fixes
1075: <ul>
1076: <li>Disabled TLSv1.0 and TLSv1.1 in libssl so that they may no longer
1077: be selected for use.
1078: <li>BN_is_prime{,_fasttest}_ex() refuse to check numbers larger than
1079: 32 kbits for primality. This mitigates various DoS vectors.
1080: <li>Restricted the RFC 3779 code to IPv4 and IPv6. It was not written
1081: to be able to deal with anything else.
1082: </ul>
1083: <li>Portable changes
1084: <ul>
1085: <li>Extended the endian.h compat header with hto* and *toh macros.
1086: <li>Adapted more tests to the portable framework.
1087: <li>Internal tools are now statically linked.
1088: <li>Applications bundled as part of the LibreSSL package internally,
1089: nc(1) and openssl(1), now are linked statically if static libraries
1090: are built.
1091: <li>Internal compatibility function symbols are no longer exported from
1092: libcrypto. Instead, the libcompat library is linked to libcrypto,
1093: libssl, and libtls separately. This increases size a little, but
1094: ensures that the libraries are not exporting symbols to programs
1095: unintentionally.
1096: <li>Selective removal of CET implementation on platforms where it is
1097: not supported (macOS).
1098: <li>Integrated four more tests.
1099: <li>Added Windows ARM64 architecture to tested platforms.
1100: <li>Removed Solaris 10 support, fixed Solaris 11.
1101: <li>libtls no longer links statically to libcrypto / libssl unless
1102: <code>--enable-libtls-only</code> is specified at configure time.
1103: <li>Improved Windows compatibility library, namely handling of files vs
1104: sockets, correcting an exception when operating on a closed socket.
1105: <li>CMake builds no longer hardcode <code>-O2</code> into the compiler flags,
1106: instead using flags from the CMake build type instead.
1107: <li>Set the CMake default build type to <code>Release</code>. This can be overridden
1108: during configuration.
1109: <li>Fixed broken ASM support with MinGW builds.
1110: </ul>
1.1 deraadt 1111: <li>New features
1112: <ul>
1.7 tb 1113: <li>Added support for truncated SHA-2 and for SHA-3.
1114: <li>The BPSW primality test performs additional Miller-Rabin rounds
1115: with random bases to reduce the likelihood of composites passing.
1116: <li>Allow testing of ciphers and digests using badly aligned buffers
1117: in openssl speed using -unalign.
1118: <li>Ed25519 certificates are now supported in openssl(1) ca and req.
1119: Prepared Ed25519 support in libssl.
1120: <li>Add branch target information (BTI) support to amd64 and arm64
1121: assembly.
1.1 deraadt 1122: </ul>
1123: <li>Compatibility changes
1124: <ul>
1.7 tb 1125: <li>Added a workaround for a poorly thought-out change in OpenSSL 3 that
1126: broke privilege separation support in libtls.
1127: <li>Moved libtls from ECDSA_METHOD to EC_KEY_METHOD.
1128: <li>Removed GF2m support: BIGNUM no longer supports binary extension
1129: field arithmetic and all binary elliptic builtin curves were removed.
1130: <li>Removed dangerous, "fast" NIST prime and elliptic curve implementations.
1131: In particular, EC_GFp_nist_method() is no longer available.
1132: <li>Removed most public symbols that were deprecated in OpenSSL 0.9.8.
1133: <li>Removed the public X9.31 API (RSA_X931_PADDING is still available).
1134: <li>Removed Cipher Text Stealing mode.
1135: <li>Removed ENGINE support, including ECDH_METHOD and ECDSA_METHOD.
1136: <li>Removed COMP, DSO, dynamic loading of conf modules and support for
1137: custom ex_data and error stacks.
1138: <li>Removed proxy certificate (RFC 3820) support.
1139: <li>Removed SXNET and NETSCAPE_CERT_SEQUENCE support including the
1.8 tb 1140: openssl(1) nseq command.
1.7 tb 1141: <li>ENGINE support was removed and OPENSSL_NO_ENGINE is set. In spite
1142: of this, some stub functions are provided to avoid patching some
1143: applications that do not honor OPENSSL_NO_ENGINE.
1144: <li>The POLICY_TREE and its related structures and API were removed.
1145: <li>In X509_VERIFY_PARAM_inherit() copy hostflags independently of the
1146: host list.
1147: <li>Made CRYPTO_get_ex_new_index() not return 0 to allow applications
1148: to use *_{get,set}_app_data() and *_{get,set}_ex_data() alongside
1149: each other.
1150: <li>X509_NAME_get_text_by_{NID,OBJ}() now only succeed if they contain
1151: valid UTF-8 without embedded NUL.
1152: <li>The explicitText user notice uses UTF8String instead of VisibleString
1153: to reduce the risk of emitting certificates with invalid DER-encoding.
1154: <li>Initial fixes for RSA-PSS support to make the TLSv1.3 stack more
1155: compliant with RFC 8446.
1156: <li>Fixed EVP_CIPHER_CTX_iv_length() to return what was set with
1157: EVP_CTRL_AEAD_SET_IVLEN or one of its aliases.
1.1 deraadt 1158: </ul>
1.7 tb 1159: <li>Internal improvements
1.1 deraadt 1160: <ul>

1162: of small primes.
1163: <li>Removed incomplete and dangerous BN_RECURSION code.
1164: <li>Imported RFC 5280 policy checking code from BoringSSL and used it
1165: to replace the old exponential time code.
1166: <li>Converted more of libcrypto to use CBB/CBS.
1167: <li>Started cleaning up and rewriting SHA internals.
1168: <li>Reduced the dependency of hash implementations on many layers of
1169: macros. This results in significant speedups since modern compilers
1170: are now less confused.
1171: <li>Improved BIGNUM internals and performance.
1172: <li>Significantly simplified the BN_BLINDING internals used in RSA.
1173: <li>Made BN_num_bits() independent of bn->top.
1174: <li>Rewrote and simplified bn_sqr().

1180: memory leaks, fixed logic errors and inconsistencies.
1181: <li>Cleaned up and simplified various ECDH and ECDSA internals.
1182: <li>Removed EC_GROUP precomp machinery.
1183: <li>Fixed various issues with EVP_PKEY_CTX_{new,dup}().
1184: <li>Rewrote OBJ_find_sigid_algs() and OBJ_find_sigid_by_algs().
1185: <li>Improved X.509 certificate version checks.
1186: <li>Ensure no X.509v3 extensions appear more than once in certificates.
1187: <li>Replaced ASN1_bn_print with a cleaner internal implementation.
1188: <li>Fix OPENSSL_cpuid_setup() invocations on arm/aarch64.

1202: and modulus in various BN_mod_* functions.
1.7 tb 1203: <li>Fixed detection of extended operations (XOP) on AMD hardware.
1204: <li>Ensure Montgomery exponentiation is used for the initial RSA blinding.
1205: <li>Policy is always checked in X509 validation. Critical policy extensions
1206: are no longer silently ignored.
1207: <li>Fixed error handling in tls_check_common_name().
1208: <li>Add missing pointer invalidation in SSL_free().
1209: <li>Fixed X509err() and X509V3err() and their internal versions.

1211: <li>Made EVP_PKEY_set1_hkdf_key() fail on a NULL key.
1212: <li>On socket errors in the poll loop, netcat could issue system calls
1213: on invalidated file descriptors.
1214: <li>Allow IP addresses to be specified in a URI.
1215: <li>Fixed a copy-paste error in ASN1_TIME_compare() that could lead
1216: to two UTCTimes or two GeneralizedTimes incorrectly being compared
1217: as equal.
1218: </ul>
1219: <li>Documentation improvements
1220: <ul>
1221: <li>Improved documentation of BIO_ctrl(3), BIO_set_info_callback(3),
1222: BIO_get_info_callback(3), BIO_method_type(3), and BIO_method_name(3).
1223: <li>Marked BIO_CB_return(), BIO_cb_pre(), and BIO_cb_post() as intentionally
1224: undocumented.
1225: <li>Made it very explicit that the verify callback should not be used.
1226: <li>Called out that the CRL lastUpdate is standardized as thisUpdate.

1.1 deraadt 1240: <ul>
1.12 dtucker 1241: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1242: generate Ed25519 keys by default. Ed25519 public keys
1243: are very convenient due to their small size. Ed25519 keys are
1244: specified in RFC 8709 and OpenSSH has supported them since version 6.5
1245: (January 2014).
1246: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1247: the Subsystem directive now accurately preserves quoting of
1248: subsystem commands and arguments. This may change behaviour for exotic
1249: configurations, but the most common subsystem configuration
1250: (sftp-server) is unlikely to be affected.
1.13 dtucker 1251: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:

1.1 deraadt 1257: <ul>
1.12 dtucker 1258: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1259: add keystroke timing obfuscation to the client. This attempts
1260: to hide inter-keystroke timings by sending interactive traffic at
1261: fixed intervals (default: every 20ms) when there is only a small
1262: amount of data being sent. It also sends fake "chaff" keystrokes for
1263: a random interval after the last real keystroke. These are
1264: controlled by a new ssh_config ObscureKeystrokeTiming keyword.
1265: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
1266: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1267: Introduce a transport-level ping facility. This adds
1268: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
1269: implement a ping capability. These messages use numbers in the "local
1270: extensions" number space and are advertised using a "ping@openssh.com"
1271: ext-info message with a string version number of "0".
1.13 dtucker 1272: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1273: allow override of Subsystem directives in sshd Match blocks.
1274: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1275: allow forwarding Unix Domain sockets via ssh -W.
1276: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1277: add support for configuration tags to ssh(1).
1278: This adds a ssh_config(5) "Tag" directive and corresponding
1279: "Match tag" predicate that may be used to select blocks of
1280: configuration similar to the pf.conf(5) keywords of the same
1281: name.
1282: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1283: add a "match localnetwork" predicate. This allows matching
1284: on the addresses of available network interfaces and may be used to
1285: vary the effective client configuration based on network location.

1289: infrastructure support for KRL
1290: extensions. This defines wire formats for optional KRL extensions
1291: and implements parsing of the new submessages. No actual extensions
1292: are supported at this point.
1293: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1294: AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
1295: accept two additional %-expansion sequences: %D which expands to
1296: the routing domain of the connected session and %C which expands
1297: to the addresses and port numbers for the source and destination
1298: of the connection.
1299: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1300: increase the default work factor (rounds) for the
1301: bcrypt KDF used to derive symmetric encryption keys for passphrase
1302: protected key files by 50%.

1.12 dtucker 1306: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
1307: fix scp in SFTP mode recursive upload and download of
1308: directories that contain symlinks to other directories. In scp mode,
1309: the links would be followed, but in SFTP mode they were not.
1310: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:

1.13 dtucker 1321: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1322: Log errors in kex_exchange_identification() with level
1.12 dtucker 1323: verbose instead of error to reduce preauth log spam. All of those
1324: get logged with a more generic error message by sshpkt_fatal().
1325: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1326: correct math for ClientAliveInterval that caused the probes
1327: to be sent less frequently than configured.
1.13 dtucker 1328: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:

1343: fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand

1.16 jsg 1350: remove vestigial support for KRL
1.13 dtucker 1351: signatures When the KRL format was originally defined, it included
1352: support for signing of KRL objects. However, the code to sign KRLs
1.16 jsg 1353: and verify KRL signatures was never completed in OpenSSH. This
1.13 dtucker 1354: release removes the partially-implemented code to verify KRLs.
1355: All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in
1356: KRL files.
1357: <li>All: fix a number of memory leaks and unreachable/harmless integer

1363: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1364: better validate CASignatureAlgorithms in
1365: ssh_config and sshd_config. Previously this directive would accept
1366: certificate algorithm names, but these were unusable in practice as
1367: OpenSSH does not support CA chains.
1368: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1369: make <code>ssh -Q CASignatureAlgorithms</code> only list signature
1370: algorithms that are valid for CA signing. Previous behaviour was
1371: to list all signing algorithms, including certificate algorithms.
1372: <li><a href="https://man.openbsd.org/ssh-keyscan.1">ssh-keyscan(1)</a>:
1373: gracefully handle systems where rlimits or the

1383: the resultant file would be erroneously truncated.
1384: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:

1685: <p>
1686: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1687: This file contains everything you need except for the kernel sources,
1688: which are in a separate archive.
1689: To extract:
1690: <blockquote><pre>
1691: # <kbd>mkdir -p /usr/src</kbd>
1692: # <kbd>cd /usr/src</kbd>
1693: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1694: </pre></blockquote>
1695: <p>
1696: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1697: This file contains all the kernel sources you need to rebuild kernels.
1698: To extract:
1699: <blockquote><pre>
1700: # <kbd>mkdir -p /usr/src/sys</kbd>
1701: # <kbd>cd /usr/src</kbd>
1702: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1703: </pre></blockquote>
1704: <p>
1705: Both of these trees are a regular CVS checkout. Using these trees it
1706: is possible to get a head-start on using the anoncvs servers as
1707: described <a href="anoncvs.html">here</a>.
1708: Using these files
1709: results in a much faster initial CVS update than you could expect from
1710: a fresh checkout of the full OpenBSD source tree.

1721: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1722: </pre></blockquote>
1723: <p>
1724: Go read the <a href="faq/ports/index.html">ports</a> page
1725: if you know nothing about ports
1726: at this point. This text is not a manual of how to use ports.
1727: Rather, it is a set of notes meant to kickstart the user on the
1728: OpenBSD ports system.
1729: <p>
1730: The <i>ports/</i> directory represents a CVS checkout of our ports.
1731: As with our complete source tree, our ports tree is available via
1732: <a href="anoncvs.html">AnonCVS</a>.
1733: So, in order to keep up to date with the -stable branch, you must make
1734: the <i>ports/</i> tree available on a read-write medium and update the tree
1735: with a command like:
1736: <blockquote><pre>
1737: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1738: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1739: </pre></blockquote>
1740: <p>
1741: [Of course, you must replace the server name here with a nearby anoncvs
1742: server.]
1743: <p>
1744: Note that most ports are available as packages on our mirrors. Updated
1745: ports for the 7.4 release will be made available if problems arise.
1746: <p>
1747: If you're interested in seeing a port added, would like to help out, or just
1748: would like to know more, the mailing list
1749: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
