1.35 benno 98: been standardized in unicode after the original wscons code was
99: written and chose placeholder values.
1.81 benno 100: <li>In <a href="https://man.openbsd.org/wscons.4">wscons(4)</a>,

1.81 benno 696:
697: <li>Initial support for TCP segmentation offload (TSO) and TCP large receive offload (LRO) was implemented:

699: <li>If the driver of a network interface supports TCP segmentation
1.69 schwarze 700: offload (TSO), do not chop the packet in the network stack,
701: but pass it down to the interface layer for TSO.
1.81 benno 702: <li>Provide a software TSO implementation, to be used as a fallback
1.69 schwarze 703: if network hardware does not support TSO.

721: interfaces by using TSO and LRO.
1.81 benno 722: <li>Enable Large Receive Offload (LRO) for TCP per default in network
1.78 benno 723: drivers. LRO allows to receive aggregated packets larger than the MTU.
724: Receiving TCP streams becomes much faster. Currently only <a
725: href="https://man.openbsd.org/ix.4">ix(4)</a> and <a

1.67 schwarze 753: when redirecting locally generated IP packets to userland with

1.81 benno 759: <li><a href="https://man.openbsd.org/pf.4">pf(4)</a> ignored 'keep
760: state' and 'nat-to' actions for unsolicited icmp error responses. With
761: OpenBSD 7.4, the rule matching logic is tightened so icmp error
762: responses no longer match 'keep state' rule. In typical scenarios icmp
763: errors (if solicited) should match existing state. The change is
764: going to bite firewalls which deal with asymmetric routes. In those
765: cases the 'keep state' action should be relaxed to sloppy or new 'no

771: wrap around after changing tcp_now() ticks to milliseconds.
1.91 schwarze 772: <li>Add initial support for route-based IPsec VPNs.<br>
773: Rather than use IPsec flows (aka, entries in the IPsec security
1.81 benno 774: policy database) to decide which traffic should be encapsulated in
1.91 schwarze 775: IPsec and sent to a peer, this changes security associations (SAs)
776: so they can also refer to a tunnel interface. When traffic is routed
777: over that tunnel interface, an IPsec SA is looked up and used to
1.81 benno 778: encapsulate traffic before being sent to the peer on the SA. When
1.91 schwarze 779: traffic is received from a peer using an interface SA, the specified
1.81 benno 780: interface is looked up and the packet is handed to it so it looks
781: like packets come out of the tunnel.

1.23 claudio 858: <li>A 30%-50% performance improvement was achieved through libcrypto's
859: partial chains certificate validation feature. Already validated
860: non-inheriting CA certificates are now marked as trusted roots. This
861: way it can be ensured that a leaf's delegated resources are properly
862: covered, and at the same time most validation paths are
863: significantly shortened.
864: <li>Support for gzip and deflate HTTP Content-Encoding compression was
865: added. This allows web servers to send RRDP XML in compressed form,
866: saving around 50% of bandwidth.
867: <li>ASPA support was updated to draft-ietf-sidrops-aspa-profile-16.
868: As part of supporting AFI-agnostic ASPAs, the JSON syntax for
869: Validated ASPA Payloads changed in both filemode and normal output.
870: <li>In filemode (-f option) the applicable manifests are now shown as
871: part of the signature path.
872: <li>A new -P option was added to manually specify a moment in time
873: to use when parsing the validity window of certificates. Useful
874: for regression testing. Default is invocation time of rpki-client.
875: <li>The -A option will now also exclude ASPA data from the JSON output.
876: <li>The synchronisation protocol used to sync the repository is now
877: included in the OpenMetrics output.
878: <li>Improved accounting by tracking objects both by repo and tal.
879: <li>Check whether products listed on a manifest were issued by the same
880: authority as the manifest itself.
881: <li>File modification timestamps of objects retrieved via RRDP are now
882: deterministically set to prepare the on-disk cache for seamless
883: failovers from RRDP to RSYNC.
884: <li>Improved detection of RRDP session desynchronization: a check was
885: added to compare whether the delta hashes associated to previously
886: seen serials are different in newly fetched notification files.
887: <li>Improved handling of RRDP deltas in which objects are published,
888: withdrawn, and published again.
889: <li>Disallow X.509 v2 issuer and subject unique identifiers in certs.
890: RPKI CAs will never issue certificates with V2 unique identifiers.
891: <li>A check to disallow duplicate X.509 certificate extensions was
892: added.
893: <li>A check to disallow empty sets of IP Addresses or AS numbers in RFC
894: 3779 extensions was added.
895: <li>A warning is printed when the CMS signing-time attribute in a Signed
896: Object is missing.
897: <li>Warnings about unrecoverable message digest mismatches now include
898: the manifestNumber to aid debugging the cause.
899: <li>A check was added to disallow multiple RRDP publish elements for the
900: same file in RRDP snapshots. If this error condition is encountered,
901: the RRDP transfer is failed and the RP falls back to rsync.
902: <li>A compliance check for the proper X.509 Certificate version and CRL
903: version was added.
904: <li>A compliance check was added to ensure CMS Signed Objects contain
905: SignedData, in accordance to RFC 6488 section 3 checklist item 1a.
906: <li>Compliance checks were added for the version, KeyUsage, and
907: ExtendedKeyUsage of EE certificates in Manifest, TAK, and GBR Signed
908: Objects.
909: <li>A CMS signing-time value being after the X.509 notAfter timestamp
910: was downgraded from an error to a warning.
911: <li>A bug was fixed in the handling of CA certificates which inherit IP
912: resources.
913: <li>A compliance check was added to ensure the X.509 Subject only
914: contains commonName and optionally serialNumber.
915: <li>A compliance check was added to ensure the CMS SignedData and
916: SignerInfo versions to be 3.
917: <li>Fisher-Yates shuffle the order in which Manifest entries are
918: processed. Previously, work items were enqueued in the order the CA

1060: <li>Internal compatibility function symbols are no longer exported from
1061: libcrypto. Instead, the libcompat library is linked to libcrypto,
1062: libssl, and libtls separately. This increases size a little, but
1063: ensures that the libraries are not exporting symbols to programs
1064: unintentionally.
1065: <li>Selective removal of CET implementation on platforms where it is
1066: not supported (macOS).
1067: <li>Integrated four more tests.
1068: <li>Added Windows ARM64 architecture to tested platforms.
1069: <li>Removed Solaris 10 support, fixed Solaris 11.
1070: <li>libtls no longer links statically to libcrypto / libssl unless
1071: <code>--enable-libtls-only</code> is specified at configure time.
1072: <li>Improved Windows compatibility library, namely handling of files vs
1073: sockets, correcting an exception when operating on a closed socket.
1074: <li>CMake builds no longer hardcode <code>-O2</code> into the compiler flags,
1075: instead using flags from the CMake build type instead.
1076: <li>Set the CMake default build type to <code>Release</code>. This can be overridden
1077: during configuration.
1078: <li>Fixed broken ASM support with MinGW builds.

1095: broke privilege separation support in libtls.
1096: <li>Moved libtls from ECDSA_METHOD to EC_KEY_METHOD.
1097: <li>Removed GF2m support: BIGNUM no longer supports binary extension
1098: field arithmetic and all binary elliptic builtin curves were removed.
1099: <li>Removed dangerous, "fast" NIST prime and elliptic curve implementations.
1100: In particular, EC_GFp_nist_method() is no longer available.
1101: <li>Removed most public symbols that were deprecated in OpenSSL 0.9.8.
1102: <li>Removed the public X9.31 API (RSA_X931_PADDING is still available).
1103: <li>Removed Cipher Text Stealing mode.
1104: <li>Removed ENGINE support, including ECDH_METHOD and ECDSA_METHOD.
1105: <li>Removed COMP, DSO, dynamic loading of conf modules and support for
1106: custom ex_data and error stacks.
1107: <li>Removed proxy certificate (RFC 3820) support.
1108: <li>Removed SXNET and NETSCAPE_CERT_SEQUENCE support including the
1.8 tb 1109: openssl(1) nseq command.
1.7 tb 1110: <li>ENGINE support was removed and OPENSSL_NO_ENGINE is set. In spite
1111: of this, some stub functions are provided to avoid patching some
1112: applications that do not honor OPENSSL_NO_ENGINE.
1113: <li>The POLICY_TREE and its related structures and API were removed.
1114: <li>In X509_VERIFY_PARAM_inherit() copy hostflags independently of the
1115: host list.
1116: <li>Made CRYPTO_get_ex_new_index() not return 0 to allow applications
1117: to use *_{get,set}_app_data() and *_{get,set}_ex_data() alongside
1118: each other.
1119: <li>X509_NAME_get_text_by_{NID,OBJ}() now only succeed if they contain
1120: valid UTF-8 without embedded NUL.
1121: <li>The explicitText user notice uses UTF8String instead of VisibleString
1122: to reduce the risk of emitting certificates with invalid DER-encoding.
1123: <li>Initial fixes for RSA-PSS support to make the TLSv1.3 stack more
1124: compliant with RFC 8446.
1125: <li>Fixed EVP_CIPHER_CTX_iv_length() to return what was set with
1126: EVP_CTRL_AEAD_SET_IVLEN or one of its aliases.

1.12 dtucker 1210: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1211: generate Ed25519 keys by default. Ed25519 public keys
1212: are very convenient due to their small size. Ed25519 keys are
1213: specified in RFC 8709 and OpenSSH has supported them since version 6.5
1214: (January 2014).
1215: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1216: the Subsystem directive now accurately preserves quoting of
1217: subsystem commands and arguments. This may change behaviour for exotic
1218: configurations, but the most common subsystem configuration
1219: (sftp-server) is unlikely to be affected.

1.12 dtucker 1227: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1228: add keystroke timing obfuscation to the client. This attempts
1229: to hide inter-keystroke timings by sending interactive traffic at
1230: fixed intervals (default: every 20ms) when there is only a small
1231: amount of data being sent. It also sends fake "chaff" keystrokes for
1232: a random interval after the last real keystroke. These are
1233: controlled by a new ssh_config ObscureKeystrokeTiming keyword.
1234: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
1235: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1236: Introduce a transport-level ping facility. This adds
1237: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
1238: implement a ping capability. These messages use numbers in the "local
1239: extensions" number space and are advertised using a "ping@openssh.com"
1240: ext-info message with a string version number of "0".
1.13 dtucker 1241: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1242: allow override of Subsystem directives in sshd Match blocks.
1243: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1244: allow forwarding Unix Domain sockets via ssh -W.
1245: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1246: add support for configuration tags to ssh(1).
1247: This adds a ssh_config(5) "Tag" directive and corresponding
1248: "Match tag" predicate that may be used to select blocks of
1249: configuration similar to the pf.conf(5) keywords of the same
1250: name.
1251: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1252: add a "match localnetwork" predicate. This allows matching
1253: on the addresses of available network interfaces and may be used to
1254: vary the effective client configuration based on network location.

1266: to the addresses and port numbers for the source and destination
1267: of the connection.
1268: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:

1291: Log errors in kex_exchange_identification() with level
1.12 dtucker 1292: verbose instead of error to reduce preauth log spam. All of those
1293: get logged with a more generic error message by sshpkt_fatal().
1294: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1295: correct math for ClientAliveInterval that caused the probes

1311: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1312: fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand

1.16 jsg 1319: remove vestigial support for KRL
1.13 dtucker 1320: signatures When the KRL format was originally defined, it included
1321: support for signing of KRL objects. However, the code to sign KRLs
1.16 jsg 1322: and verify KRL signatures was never completed in OpenSSH. This
1.13 dtucker 1323: release removes the partially-implemented code to verify KRLs.
1324: All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in

1333: better validate CASignatureAlgorithms in

1336: OpenSSH does not support CA chains.
1337: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1338: make <code>ssh -Q CASignatureAlgorithms</code> only list signature

1340: to list all signing algorithms, including certificate algorithms.
1341: <li><a href="https://man.openbsd.org/ssh-keyscan.1">ssh-keyscan(1)</a>:

1653: <h3>Notes about the source code</h3>
1654: <p>
1655: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1656: This file contains everything you need except for the kernel sources,
1657: which are in a separate archive.
1658: To extract:
1659: <blockquote><pre>
1660: # <kbd>mkdir -p /usr/src</kbd>
1661: # <kbd>cd /usr/src</kbd>
1662: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1663: </pre></blockquote>
1664: <p>
1665: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1666: This file contains all the kernel sources you need to rebuild kernels.
1667: To extract:
1668: <blockquote><pre>
1669: # <kbd>mkdir -p /usr/src/sys</kbd>
1670: # <kbd>cd /usr/src</kbd>
1671: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1672: </pre></blockquote>
1673: <p>
1674: Both of these trees are a regular CVS checkout. Using these trees it
1675: is possible to get a head-start on using the anoncvs servers as
1676: described <a href="anoncvs.html">here</a>.
1677: Using these files
1678: results in a much faster initial CVS update than you could expect from
1679: a fresh checkout of the full OpenBSD source tree.

1688: <blockquote><pre>
1689: # <kbd>cd /usr</kbd>
1690: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1691: </pre></blockquote>
1692: <p>
1693: Go read the <a href="faq/ports/index.html">ports</a> page
1694: if you know nothing about ports
1695: at this point. This text is not a manual of how to use ports.
1696: Rather, it is a set of notes meant to kickstart the user on the
1697: OpenBSD ports system.
1698: <p>
1699: The <i>ports/</i> directory represents a CVS checkout of our ports.
1700: As with our complete source tree, our ports tree is available via
1701: <a href="anoncvs.html">AnonCVS</a>.
1702: So, in order to keep up to date with the -stable branch, you must make
1703: the <i>ports/</i> tree available on a read-write medium and update the tree
1704: with a command like:
1705: <blockquote><pre>
1706: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1707: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1708: </pre></blockquote>
1709: <p>
1710: [Of course, you must replace the server name here with a nearby anoncvs
1711: server.]
1712: <p>
1713: Note that most ports are available as packages on our mirrors. Updated
1714: ports for the 7.4 release will be made available if problems arise.
1715: <p>
1716: If you're interested in seeing a port added, would like to help out, or just
1717: would like to know more, the mailing list
1718: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
