1.81 benno 737: <li>Enable Large Receive Offload (LRO) for TCP per default in network
1.78 benno 738: drivers. LRO allows to receive aggregated packets larger than the MTU.
739: Receiving TCP streams becomes much faster. Currently only <a

1.81 benno 774: <li><a href="https://man.openbsd.org/pf.4">pf(4)</a> ignored 'keep
775: state' and 'nat-to' actions for unsolicited icmp error responses. With
776: OpenBSD 7.4, the rule matching logic is tightened so icmp error
777: responses no longer match 'keep state' rule. In typical scenarios icmp
778: errors (if solicited) should match existing state. The change is
779: going to bite firewalls which deal with asymmetric routes. In those
780: cases the 'keep state' action should be relaxed to sloppy or new 'no

786: wrap around after changing tcp_now() ticks to milliseconds.
1.81 benno 787: <li>Added initial support for route-based ipsec vpns.<br>
788: Rather than use ipsec flows (aka, entries in the ipsec security
789: policy database) to decide which traffic should be encapsulated in
790: ipsec and sent to a peer, this changes security associations (SAs)
791: so they can also refer to a tunnel interface. When traffic is routed
792: over that tunnel interface, an ipsec SA is looked up and used to
793: encapsulate traffic before being sent to the peer on the SA. When
794: traffic is received from a peer using an interface SA, the specified
795: interface is looked up and the packet is handed to it so it looks
796: like packets come out of the tunnel.
797: <li>Add <a href="https://man.openbsd.org/sec.4">sec(4)</a> to support
798: route based ipsec vpns.
799: <li>Introduce reference counting for TCP syn cache entries.

874: partial chains certificate validation feature. Already validated
875: non-inheriting CA certificates are now marked as trusted roots. This
876: way it can be ensured that a leaf's delegated resources are properly
877: covered, and at the same time most validation paths are
878: significantly shortened.
879: <li>Support for gzip and deflate HTTP Content-Encoding compression was
880: added. This allows web servers to send RRDP XML in compressed form,
881: saving around 50% of bandwidth.
882: <li>ASPA support was updated to draft-ietf-sidrops-aspa-profile-16.
883: As part of supporting AFI-agnostic ASPAs, the JSON syntax for
884: Validated ASPA Payloads changed in both filemode and normal output.
885: <li>In filemode (-f option) the applicable manifests are now shown as
886: part of the signature path.
887: <li>A new -P option was added to manually specify a moment in time
888: to use when parsing the validity window of certificates. Useful
889: for regression testing. Default is invocation time of rpki-client.

891: <li>The synchronisation protocol used to sync the repository is now
892: included in the OpenMetrics output.
893: <li>Improved accounting by tracking objects both by repo and tal.
894: <li>Check whether products listed on a manifest were issued by the same
895: authority as the manifest itself.
896: <li>File modification timestamps of objects retrieved via RRDP are now
897: deterministically set to prepare the on-disk cache for seamless
898: failovers from RRDP to RSYNC.
899: <li>Improved detection of RRDP session desynchronization: a check was

905: RPKI CAs will never issue certificates with V2 unique identifiers.
906: <li>A check to disallow duplicate X.509 certificate extensions was
907: added.
908: <li>A check to disallow empty sets of IP Addresses or AS numbers in RFC
909: 3779 extensions was added.
910: <li>A warning is printed when the CMS signing-time attribute in a Signed
911: Object is missing.
912: <li>Warnings about unrecoverable message digest mismatches now include
913: the manifestNumber to aid debugging the cause.
914: <li>A check was added to disallow multiple RRDP publish elements for the
915: same file in RRDP snapshots. If this error condition is encountered,
916: the RRDP transfer is failed and the RP falls back to rsync.
917: <li>A compliance check for the proper X.509 Certificate version and CRL
918: version was added.
919: <li>A compliance check was added to ensure CMS Signed Objects contain
920: SignedData, in accordance to RFC 6488 section 3 checklist item 1a.
921: <li>Compliance checks were added for the version, KeyUsage, and
922: ExtendedKeyUsage of EE certificates in Manifest, TAK, and GBR Signed
923: Objects.
924: <li>A CMS signing-time value being after the X.509 notAfter timestamp
925: was downgraded from an error to a warning.
926: <li>A bug was fixed in the handling of CA certificates which inherit IP
927: resources.
928: <li>A compliance check was added to ensure the X.509 Subject only

931: SignerInfo versions to be 3.
932: <li>Fisher-Yates shuffle the order in which Manifest entries are

1062: <li>BN_is_prime{,_fasttest}_ex() refuse to check numbers larger than
1063: 32 kbits for primality. This mitigates various DoS vectors.
1064: <li>Restricted the RFC 3779 code to IPv4 and IPv6. It was not written
1065: to be able to deal with anything else.
1066: </ul>
1067: <li>Portable changes
1068: <ul>
1069: <li>Extended the endian.h compat header with hto* and *toh macros.

1074: are built.
1075: <li>Internal compatibility function symbols are no longer exported from
1076: libcrypto. Instead, the libcompat library is linked to libcrypto,
1077: libssl, and libtls separately. This increases size a little, but
1078: ensures that the libraries are not exporting symbols to programs
1079: unintentionally.
1080: <li>Selective removal of CET implementation on platforms where it is
1081: not supported (macOS).
1082: <li>Integrated four more tests.
1083: <li>Added Windows ARM64 architecture to tested platforms.
1084: <li>Removed Solaris 10 support, fixed Solaris 11.
1085: <li>libtls no longer links statically to libcrypto / libssl unless
1086: <code>--enable-libtls-only</code> is specified at configure time.
1087: <li>Improved Windows compatibility library, namely handling of files vs
1088: sockets, correcting an exception when operating on a closed socket.
1089: <li>CMake builds no longer hardcode <code>-O2</code> into the compiler flags,
1090: instead using flags from the CMake build type instead.
1091: <li>Set the CMake default build type to <code>Release</code>. This can be overridden
1092: during configuration.
1093: <li>Fixed broken ASM support with MinGW builds.

1099: with random bases to reduce the likelihood of composites passing.
1100: <li>Allow testing of ciphers and digests using badly aligned buffers
1101: in openssl speed using -unalign.

1110: broke privilege separation support in libtls.
1111: <li>Moved libtls from ECDSA_METHOD to EC_KEY_METHOD.
1112: <li>Removed GF2m support: BIGNUM no longer supports binary extension
1113: field arithmetic and all binary elliptic builtin curves were removed.
1114: <li>Removed dangerous, "fast" NIST prime and elliptic curve implementations.
1115: In particular, EC_GFp_nist_method() is no longer available.
1116: <li>Removed most public symbols that were deprecated in OpenSSL 0.9.8.
1117: <li>Removed the public X9.31 API (RSA_X931_PADDING is still available).
1118: <li>Removed Cipher Text Stealing mode.
1119: <li>Removed ENGINE support, including ECDH_METHOD and ECDSA_METHOD.
1120: <li>Removed COMP, DSO, dynamic loading of conf modules and support for
1121: custom ex_data and error stacks.
1122: <li>Removed proxy certificate (RFC 3820) support.
1123: <li>Removed SXNET and NETSCAPE_CERT_SEQUENCE support including the
1.8 tb 1124: openssl(1) nseq command.
1.7 tb 1125: <li>ENGINE support was removed and OPENSSL_NO_ENGINE is set. In spite
1126: of this, some stub functions are provided to avoid patching some
1127: applications that do not honor OPENSSL_NO_ENGINE.
1128: <li>The POLICY_TREE and its related structures and API were removed.
1129: <li>In X509_VERIFY_PARAM_inherit() copy hostflags independently of the
1130: host list.
1131: <li>Made CRYPTO_get_ex_new_index() not return 0 to allow applications
1132: to use *_{get,set}_app_data() and *_{get,set}_ex_data() alongside
1133: each other.
1134: <li>X509_NAME_get_text_by_{NID,OBJ}() now only succeed if they contain
1135: valid UTF-8 without embedded NUL.
1136: <li>The explicitText user notice uses UTF8String instead of VisibleString
1137: to reduce the risk of emitting certificates with invalid DER-encoding.
1138: <li>Initial fixes for RSA-PSS support to make the TLSv1.3 stack more
1139: compliant with RFC 8446.
1140: <li>Fixed EVP_CIPHER_CTX_iv_length() to return what was set with
1141: EVP_CTRL_AEAD_SET_IVLEN or one of its aliases.

1150: <li>Converted more of libcrypto to use CBB/CBS.
1151: <li>Started cleaning up and rewriting SHA internals.
1152: <li>Reduced the dependency of hash implementations on many layers of
1153: macros. This results in significant speedups since modern compilers
1154: are now less confused.
1155: <li>Improved BIGNUM internals and performance.
1156: <li>Significantly simplified the BN_BLINDING internals used in RSA.
1157: <li>Made BN_num_bits() independent of bn->top.

1164: memory leaks, fixed logic errors and inconsistencies.
1165: <li>Cleaned up and simplified various ECDH and ECDSA internals.
1166: <li>Removed EC_GROUP precomp machinery.
1167: <li>Fixed various issues with EVP_PKEY_CTX_{new,dup}().

1.12 dtucker 1225: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1226: generate Ed25519 keys by default. Ed25519 public keys
1227: are very convenient due to their small size. Ed25519 keys are
1228: specified in RFC 8709 and OpenSSH has supported them since version 6.5

1230: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1231: the Subsystem directive now accurately preserves quoting of

1.12 dtucker 1242: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1243: add keystroke timing obfuscation to the client. This attempts
1244: to hide inter-keystroke timings by sending interactive traffic at
1245: fixed intervals (default: every 20ms) when there is only a small
1246: amount of data being sent. It also sends fake "chaff" keystrokes for
1247: a random interval after the last real keystroke. These are
1248: controlled by a new ssh_config ObscureKeystrokeTiming keyword.
1249: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
1250: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1251: Introduce a transport-level ping facility. This adds
1252: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
1253: implement a ping capability. These messages use numbers in the "local
1254: extensions" number space and are advertised using a "ping@openssh.com"
1255: ext-info message with a string version number of "0".
1.13 dtucker 1256: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:

1259: allow forwarding Unix Domain sockets via ssh -W.
1260: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1261: add support for configuration tags to ssh(1).
1262: This adds a ssh_config(5) "Tag" directive and corresponding
1263: "Match tag" predicate that may be used to select blocks of
1264: configuration similar to the pf.conf(5) keywords of the same
1265: name.
1266: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:

1669: <p>
1670: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1671: This file contains everything you need except for the kernel sources,
1672: which are in a separate archive.
1673: To extract:
1674: <blockquote><pre>
1675: # <kbd>mkdir -p /usr/src</kbd>
1676: # <kbd>cd /usr/src</kbd>
1677: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1678: </pre></blockquote>
1679: <p>
1680: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1681: This file contains all the kernel sources you need to rebuild kernels.
1682: To extract:
1683: <blockquote><pre>
1684: # <kbd>mkdir -p /usr/src/sys</kbd>
1685: # <kbd>cd /usr/src</kbd>
1686: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1687: </pre></blockquote>
1688: <p>
1689: Both of these trees are a regular CVS checkout. Using these trees it
1690: is possible to get a head-start on using the anoncvs servers as
1691: described <a href="anoncvs.html">here</a>.
1692: Using these files
1693: results in a much faster initial CVS update than you could expect from
1694: a fresh checkout of the full OpenBSD source tree.

1708: Go read the <a href="faq/ports/index.html">ports</a> page
1709: if you know nothing about ports
1710: at this point. This text is not a manual of how to use ports.
1711: Rather, it is a set of notes meant to kickstart the user on the
1712: OpenBSD ports system.
1713: <p>
1714: The <i>ports/</i> directory represents a CVS checkout of our ports.
1715: As with our complete source tree, our ports tree is available via
1716: <a href="anoncvs.html">AnonCVS</a>.
1717: So, in order to keep up to date with the -stable branch, you must make
1718: the <i>ports/</i> tree available on a read-write medium and update the tree
1719: with a command like:
1720: <blockquote><pre>
1721: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1722: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1723: </pre></blockquote>
1724: <p>
1725: [Of course, you must replace the server name here with a nearby anoncvs
1726: server.]
1727: <p>
1728: Note that most ports are available as packages on our mirrors. Updated
1729: ports for the 7.4 release will be made available if problems arise.
1730: <p>
1731: If you're interested in seeing a port added, would like to help out, or just
1732: would like to know more, the mailing list
1733: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
