770: <ul>
1.23 claudio 771: <li>A 30%-50% performance improvement was achieved through libcrypto's
772: partial chains certificate validation feature. Already validated
773: non-inheriting CA certificates are now marked as trusted roots. This
774: way it can be ensured that a leaf's delegated resources are properly
775: covered, and at the same time most validation paths are
776: significantly shortened.
777: <li>Support for gzip and deflate HTTP Content-Encoding compression was
778: added. This allows web servers to send RRDP XML in compressed form,
779: saving around 50% of bandwidth.
780: <li>ASPA support was updated to draft-ietf-sidrops-aspa-profile-16.
781: As part of supporting AFI-agnostic ASPAs, the JSON syntax for
782: Validated ASPA Payloads changed in both filemode and normal output.
783: <li>In filemode (-f option) the applicable manifests are now shown as
784: part of the signature path.
785: <li>A new -P option was added to manually specify a moment in time
786: to use when parsing the validity window of certificates. Useful
787: for regression testing. Default is invocation time of rpki-client.
788: <li>The -A option will now also exclude ASPA data from the JSON output.
789: <li>The synchronisation protocol used to sync the repository is now
790: included in the OpenMetrics output.
791: <li>Improved accounting by tracking objects both by repo and tal.
792: <li>Check whether products listed on a manifest were issued by the same
793: authority as the manifest itself.
794: <li>File modification timestamps of objects retrieved via RRDP are now
795: deterministically set to prepare the on-disk cache for seamless
796: failovers from RRDP to RSYNC.
797: <li>Improved detection of RRDP session desynchronization: a check was
798: added to compare whether the delta hashes associated to previously
799: seen serials are different in newly fetched notification files.
800: <li>Improved handling of RRDP deltas in which objects are published,
801: withdrawn, and published again.
802: <li>Disallow X.509 v2 issuer and subject unique identifiers in certs.
803: RPKI CAs will never issue certificates with V2 unique identifiers.
804: <li>A check to disallow duplicate X.509 certificate extensions was
805: added.
806: <li>A check to disallow empty sets of IP Addresses or AS numbers in RFC
807: 3779 extensions was added.
808: <li>A warning is printed when the CMS signing-time attribute in a Signed
809: Object is missing.
810: <li>Warnings about unrecoverable message digest mismatches now include
811: the manifestNumber to aid debugging the cause.
812: <li>A check was added to disallow multiple RRDP publish elements for the
813: same file in RRDP snapshots. If this error condition is encountered,
814: the RRDP transfer is failed and the RP falls back to rsync.
815: <li>A compliance check for the proper X.509 Certificate version and CRL
816: version was added.
817: <li>A compliance check was added to ensure CMS Signed Objects contain
818: SignedData, in accordance to RFC 6488 section 3 checklist item 1a.
819: <li>Compliance checks were added for the version, KeyUsage, and
820: ExtendedKeyUsage of EE certificates in Manifest, TAK, and GBR Signed
821: Objects.
822: <li>A CMS signing-time value being after the X.509 notAfter timestamp
823: was downgraded from an error to a warning.
824: <li>A bug was fixed in the handling of CA certificates which inherit IP
825: resources.
826: <li>A compliance check was added to ensure the X.509 Subject only
827: contains commonName and optionally serialNumber.
828: <li>A compliance check was added to ensure the CMS SignedData and
829: SignerInfo versions to be 3.
830: <li>Fisher-Yates shuffle the order in which Manifest entries are
831: processed. Previously, work items were enqueued in the order the CA

1053: on invalidated file descriptors.
1054: <li>Allow IP addresses to be specified in a URI.
1055: <li>Fixed a copy-paste error in ASN1_TIME_compare() that could lead

1057: as equal.
1058: </ul>
1059: <li>Documentation improvements

1063: <li>Marked BIO_CB_return(), BIO_cb_pre(), and BIO_cb_post() as intentionally
1064: undocumented.
1065: <li>Made it very explicit that the verify callback should not be used.

1.12 dtucker 1079: <li>Potentially incompatible changes
1.1 deraadt 1080: <ul>
1.12 dtucker 1081: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1082: generate Ed25519 keys by default. Ed25519 public keys
1083: are very convenient due to their small size. Ed25519 keys are
1084: specified in RFC 8709 and OpenSSH has supported them since version 6.5
1085: (January 2014).
1086: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1087: the Subsystem directive now accurately preserves quoting of
1088: subsystem commands and arguments. This may change behaviour for exotic
1089: configurations, but the most common subsystem configuration
1090: (sftp-server) is unlikely to be affected.
1.13 dtucker 1091: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
1092: PKCS#11 modules must now be specified by their full
1093: paths. Previously dlopen(3) could search for them in system
1094: library directories.
1.1 deraadt 1095: </ul>
1.12 dtucker 1096: <li>New features
1.1 deraadt 1097: <ul>
1.12 dtucker 1098: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1099: add keystroke timing obfuscation to the client. This attempts
1100: to hide inter-keystroke timings by sending interactive traffic at
1101: fixed intervals (default: every 20ms) when there is only a small
1102: amount of data being sent. It also sends fake "chaff" keystrokes for
1103: a random interval after the last real keystroke. These are
1104: controlled by a new ssh_config ObscureKeystrokeTiming keyword.
1105: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
1106: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1107: Introduce a transport-level ping facility. This adds
1108: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
1109: implement a ping capability. These messages use numbers in the "local
1110: extensions" number space and are advertised using a "ping@openssh.com"
1111: ext-info message with a string version number of "0".
1.13 dtucker 1112: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1113: allow override of Subsystem directives in sshd Match blocks.
1114: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1115: allow forwarding Unix Domain sockets via ssh -W.
1116: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1117: add support for configuration tags to ssh(1).
1118: This adds a ssh_config(5) "Tag" directive and corresponding
1119: "Match tag" predicate that may be used to select blocks of
1120: configuration similar to the pf.conf(5) keywords of the same
1121: name.
1122: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1123: add a "match localnetwork" predicate. This allows matching
1124: on the addresses of available network interfaces and may be used to
1125: vary the effective client configuration based on network location.
1126: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
1127: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
1128: <a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1129: infrastructure support for KRL
1130: extensions. This defines wire formats for optional KRL extensions
1131: and implements parsing of the new submessages. No actual extensions
1132: are supported at this point.
1133: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1134: AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
1135: accept two additional %-expansion sequences: %D which expands to
1136: the routing domain of the connected session and %C which expands
1137: to the addresses and port numbers for the source and destination
1138: of the connection.
1139: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1140: increase the default work factor (rounds) for the
1141: bcrypt KDF used to derive symmetric encryption keys for passphrase
1142: protected key files by 50%.
1.1 deraadt 1143: </ul>
1144: <li>Bugfixes
1145: <ul>
1.12 dtucker 1146: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
1147: fix scp in SFTP mode recursive upload and download of
1148: directories that contain symlinks to other directories. In scp mode,
1149: the links would be followed, but in SFTP mode they were not.
1150: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1151: handle cr+lf (instead of just cr) line endings in
1152: sshsig signature files.
1153: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1154: interactive mode for ControlPersist sessions if they
1155: originally requested a tty.
1156: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1157: make PerSourceMaxStartups first-match-wins
1158: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1159: limit artificial login delay to a reasonable maximum (5s)
1160: and don't delay at all for the "none" authentication mechanism.
1.13 dtucker 1161: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1162: Log errors in kex_exchange_identification() with level
1.12 dtucker 1163: verbose instead of error to reduce preauth log spam. All of those
1164: get logged with a more generic error message by sshpkt_fatal().
1165: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1166: correct math for ClientAliveInterval that caused the probes
1167: to be sent less frequently than configured.
1.13 dtucker 1168: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
1169: improve isolation between loaded PKCS#11 modules
1170: by running separate ssh-pkcs11-helpers for each loaded provider.
1171: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1172: make -f (fork after authentication) work correctly with
1173: multiplexed connections, including ControlPersist.
1174: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1175: make ConnectTimeout apply to multiplexing sockets and not
1176: just to network connections.
1177: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
1178: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1179: improve defences against invalid PKCS#11
1180: modules being loaded by checking that the requested module
1181: contains the required symbol before loading it.
1182: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1183: fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand
1184: appears before it in sshd_config. Since OpenSSH 8.7 the
1185: AuthorizedPrincipalsCommand directive was incorrectly ignored in
1186: this situation.

1.16 jsg 1190: remove vestigial support for KRL
1.13 dtucker 1191: signatures When the KRL format was originally defined, it included
1192: support for signing of KRL objects. However, the code to sign KRLs
1.16 jsg 1193: and verify KRL signatures was never completed in OpenSSH. This
1.13 dtucker 1194: release removes the partially-implemented code to verify KRLs.
1195: All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in
1196: KRL files.
1197: <li>All: fix a number of memory leaks and unreachable/harmless integer
1198: overflows.
1199: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
1200: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1201: don't truncate strings logged from PKCS#11 modules
1202: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
1203: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1204: better validate CASignatureAlgorithms in
1205: ssh_config and sshd_config. Previously this directive would accept
1206: certificate algorithm names, but these were unusable in practice as
1207: OpenSSH does not support CA chains.
1208: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1209: make <code>ssh -Q CASignatureAlgorithms</code> only list signature
1210: algorithms that are valid for CA signing. Previous behaviour was
1211: to list all signing algorithms, including certificate algorithms.
1212: <li><a href="https://man.openbsd.org/ssh-keyscan.1">ssh-keyscan(1)</a>:
1213: gracefully handle systems where rlimits or the
1214: maximum number of open files is larger than INT_MAX
1215: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1216: fix "no comment" not showing on when running
1217: <code>ssh-keygen -l</code> on multiple keys where one has a comment
1218: and other following keys do not.
1219: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>,
1.14 dtucker 1220: <a href="https://man.openbsd.org/sftp.1">sftp(1)</a>:
1.13 dtucker 1221: adjust ftruncate() logic to handle servers that
1222: reorder requests. Previously, if the server reordered requests then
1223: the resultant file would be erroneously truncated.
1224: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1225: don't incorrectly disable hostname canonicalization when
1.16 jsg 1226: CanonicalizeHostname=yes and ProxyJump was explicitly set to
1.13 dtucker 1227: "none".
1228: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
1229: when copying local to remote, check that the source file

1.1 deraadt 1517: upgrade instructions and advice can be found in the

1523: <section id=sourcecode>
1524: <h3>Notes about the source code</h3>
1525: <p>
1526: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1527: This file contains everything you need except for the kernel sources,
1528: which are in a separate archive.
1529: To extract:
1530: <blockquote><pre>
1531: # <kbd>mkdir -p /usr/src</kbd>
1532: # <kbd>cd /usr/src</kbd>
1533: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1534: </pre></blockquote>
1535: <p>
1536: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1537: This file contains all the kernel sources you need to rebuild kernels.
1538: To extract:
1539: <blockquote><pre>
1540: # <kbd>mkdir -p /usr/src/sys</kbd>
1541: # <kbd>cd /usr/src</kbd>
1542: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1543: </pre></blockquote>
1544: <p>
1545: Both of these trees are a regular CVS checkout. Using these trees it
1546: is possible to get a head-start on using the anoncvs servers as
1547: described <a href="anoncvs.html">here</a>.
1548: Using these files
1549: results in a much faster initial CVS update than you could expect from
1550: a fresh checkout of the full OpenBSD source tree.

1557: <p>
1558: A ports tree archive is also provided. To extract:
1559: <blockquote><pre>
1560: # <kbd>cd /usr</kbd>
1561: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1562: </pre></blockquote>
1563: <p>
1564: Go read the <a href="faq/ports/index.html">ports</a> page
1565: if you know nothing about ports
1566: at this point. This text is not a manual of how to use ports.
1567: Rather, it is a set of notes meant to kickstart the user on the
1568: OpenBSD ports system.
1569: <p>
1570: The <i>ports/</i> directory represents a CVS checkout of our ports.
1571: As with our complete source tree, our ports tree is available via
1572: <a href="anoncvs.html">AnonCVS</a>.
1573: So, in order to keep up to date with the -stable branch, you must make
1574: the <i>ports/</i> tree available on a read-write medium and update the tree
1575: with a command like:
1576: <blockquote><pre>
1577: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1578: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1579: </pre></blockquote>
1580: <p>
1581: [Of course, you must replace the server name here with a nearby anoncvs
1582: server.]
1583: <p>
1584: Note that most ports are available as packages on our mirrors. Updated
1585: ports for the 7.4 release will be made available if problems arise.
1586: <p>
1587: If you're interested in seeing a port added, would like to help out, or just
1588: would like to know more, the mailing list
1589: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
