805: <ul>
1.23 claudio 806: <li>A 30%-50% performance improvement was achieved through libcrypto's
807: partial chains certificate validation feature. Already validated
808: non-inheriting CA certificates are now marked as trusted roots. This
809: way it can be ensured that a leaf's delegated resources are properly
810: covered, and at the same time most validation paths are
811: significantly shortened.
812: <li>Support for gzip and deflate HTTP Content-Encoding compression was
813: added. This allows web servers to send RRDP XML in compressed form,
814: saving around 50% of bandwidth.
815: <li>ASPA support was updated to draft-ietf-sidrops-aspa-profile-16.
816: As part of supporting AFI-agnostic ASPAs, the JSON syntax for
817: Validated ASPA Payloads changed in both filemode and normal output.
818: <li>In filemode (-f option) the applicable manifests are now shown as
819: part of the signature path.
820: <li>A new -P option was added to manually specify a moment in time
821: to use when parsing the validity window of certificates. Useful
822: for regression testing. Default is invocation time of rpki-client.
823: <li>The -A option will now also exclude ASPA data from the JSON output.
824: <li>The synchronisation protocol used to sync the repository is now
825: included in the OpenMetrics output.
826: <li>Improved accounting by tracking objects both by repo and tal.
827: <li>Check whether products listed on a manifest were issued by the same
828: authority as the manifest itself.
829: <li>File modification timestamps of objects retrieved via RRDP are now
830: deterministically set to prepare the on-disk cache for seamless
831: failovers from RRDP to RSYNC.
832: <li>Improved detection of RRDP session desynchronization: a check was
833: added to compare whether the delta hashes associated to previously
834: seen serials are different in newly fetched notification files.
835: <li>Improved handling of RRDP deltas in which objects are published,
836: withdrawn, and published again.
837: <li>Disallow X.509 v2 issuer and subject unique identifiers in certs.
838: RPKI CAs will never issue certificates with V2 unique identifiers.
839: <li>A check to disallow duplicate X.509 certificate extensions was
840: added.
841: <li>A check to disallow empty sets of IP Addresses or AS numbers in RFC
842: 3779 extensions was added.
843: <li>A warning is printed when the CMS signing-time attribute in a Signed
844: Object is missing.
845: <li>Warnings about unrecoverable message digest mismatches now include
846: the manifestNumber to aid debugging the cause.
847: <li>A check was added to disallow multiple RRDP publish elements for the
848: same file in RRDP snapshots. If this error condition is encountered,
849: the RRDP transfer is failed and the RP falls back to rsync.
850: <li>A compliance check for the proper X.509 Certificate version and CRL
851: version was added.
852: <li>A compliance check was added to ensure CMS Signed Objects contain
853: SignedData, in accordance to RFC 6488 section 3 checklist item 1a.
854: <li>Compliance checks were added for the version, KeyUsage, and
855: ExtendedKeyUsage of EE certificates in Manifest, TAK, and GBR Signed
856: Objects.
857: <li>A CMS signing-time value being after the X.509 notAfter timestamp
858: was downgraded from an error to a warning.
859: <li>A bug was fixed in the handling of CA certificates which inherit IP
860: resources.
861: <li>A compliance check was added to ensure the X.509 Subject only
862: contains commonName and optionally serialNumber.
863: <li>A compliance check was added to ensure the CMS SignedData and
864: SignerInfo versions to be 3.
865: <li>Fisher-Yates shuffle the order in which Manifest entries are
866: processed. Previously, work items were enqueued in the order the CA

1.12 dtucker 1114: <li>Potentially incompatible changes
1.1 deraadt 1115: <ul>
1.12 dtucker 1116: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1117: generate Ed25519 keys by default. Ed25519 public keys
1118: are very convenient due to their small size. Ed25519 keys are
1119: specified in RFC 8709 and OpenSSH has supported them since version 6.5
1120: (January 2014).
1121: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1122: the Subsystem directive now accurately preserves quoting of
1123: subsystem commands and arguments. This may change behaviour for exotic
1124: configurations, but the most common subsystem configuration
1125: (sftp-server) is unlikely to be affected.
1.13 dtucker 1126: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
1127: PKCS#11 modules must now be specified by their full
1128: paths. Previously dlopen(3) could search for them in system
1129: library directories.
1.1 deraadt 1130: </ul>
1.12 dtucker 1131: <li>New features
1.1 deraadt 1132: <ul>
1.12 dtucker 1133: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1134: add keystroke timing obfuscation to the client. This attempts
1135: to hide inter-keystroke timings by sending interactive traffic at
1136: fixed intervals (default: every 20ms) when there is only a small
1137: amount of data being sent. It also sends fake "chaff" keystrokes for
1138: a random interval after the last real keystroke. These are
1139: controlled by a new ssh_config ObscureKeystrokeTiming keyword.
1140: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
1141: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1142: Introduce a transport-level ping facility. This adds
1143: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
1144: implement a ping capability. These messages use numbers in the "local
1145: extensions" number space and are advertised using a "ping@openssh.com"
1146: ext-info message with a string version number of "0".
1.13 dtucker 1147: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1148: allow override of Subsystem directives in sshd Match blocks.
1149: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1150: allow forwarding Unix Domain sockets via ssh -W.
1151: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1152: add support for configuration tags to ssh(1).
1153: This adds a ssh_config(5) "Tag" directive and corresponding
1154: "Match tag" predicate that may be used to select blocks of
1155: configuration similar to the pf.conf(5) keywords of the same
1156: name.
1157: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1158: add a "match localnetwork" predicate. This allows matching
1159: on the addresses of available network interfaces and may be used to
1160: vary the effective client configuration based on network location.
1161: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
1162: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
1163: <a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1164: infrastructure support for KRL
1165: extensions. This defines wire formats for optional KRL extensions
1166: and implements parsing of the new submessages. No actual extensions
1167: are supported at this point.
1168: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1169: AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
1170: accept two additional %-expansion sequences: %D which expands to
1171: the routing domain of the connected session and %C which expands
1172: to the addresses and port numbers for the source and destination
1173: of the connection.
1174: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1175: increase the default work factor (rounds) for the
1176: bcrypt KDF used to derive symmetric encryption keys for passphrase
1177: protected key files by 50%.
1.1 deraadt 1178: </ul>
1179: <li>Bugfixes
1180: <ul>
1.12 dtucker 1181: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
1182: fix scp in SFTP mode recursive upload and download of
1183: directories that contain symlinks to other directories. In scp mode,
1184: the links would be followed, but in SFTP mode they were not.
1185: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1186: handle cr+lf (instead of just cr) line endings in
1187: sshsig signature files.
1188: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1189: interactive mode for ControlPersist sessions if they
1190: originally requested a tty.
1191: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1192: make PerSourceMaxStartups first-match-wins
1193: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1194: limit artificial login delay to a reasonable maximum (5s)
1195: and don't delay at all for the "none" authentication mechanism.
1.13 dtucker 1196: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1197: Log errors in kex_exchange_identification() with level
1.12 dtucker 1198: verbose instead of error to reduce preauth log spam. All of those
1199: get logged with a more generic error message by sshpkt_fatal().
1200: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1201: correct math for ClientAliveInterval that caused the probes
1202: to be sent less frequently than configured.
1.13 dtucker 1203: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
1204: improve isolation between loaded PKCS#11 modules
1205: by running separate ssh-pkcs11-helpers for each loaded provider.
1206: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1207: make -f (fork after authentication) work correctly with
1208: multiplexed connections, including ControlPersist.
1209: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1210: make ConnectTimeout apply to multiplexing sockets and not
1211: just to network connections.
1212: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
1213: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1214: improve defences against invalid PKCS#11
1215: modules being loaded by checking that the requested module
1216: contains the required symbol before loading it.
1217: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1218: fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand
1219: appears before it in sshd_config. Since OpenSSH 8.7 the
1220: AuthorizedPrincipalsCommand directive was incorrectly ignored in
1221: this situation.
1222: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,

1224: <a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1.16 jsg 1225: remove vestigial support for KRL
1.13 dtucker 1226: signatures When the KRL format was originally defined, it included
1227: support for signing of KRL objects. However, the code to sign KRLs
1.16 jsg 1228: and verify KRL signatures was never completed in OpenSSH. This
1.13 dtucker 1229: release removes the partially-implemented code to verify KRLs.
1230: All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in
1231: KRL files.
1232: <li>All: fix a number of memory leaks and unreachable/harmless integer
1233: overflows.
1234: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
1235: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1236: don't truncate strings logged from PKCS#11 modules
1237: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
1238: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1239: better validate CASignatureAlgorithms in
1240: ssh_config and sshd_config. Previously this directive would accept
1241: certificate algorithm names, but these were unusable in practice as
1242: OpenSSH does not support CA chains.
1243: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1244: make <code>ssh -Q CASignatureAlgorithms</code> only list signature
1245: algorithms that are valid for CA signing. Previous behaviour was
1246: to list all signing algorithms, including certificate algorithms.
1247: <li><a href="https://man.openbsd.org/ssh-keyscan.1">ssh-keyscan(1)</a>:
1248: gracefully handle systems where rlimits or the
1249: maximum number of open files is larger than INT_MAX
1250: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1251: fix "no comment" not showing on when running
1252: <code>ssh-keygen -l</code> on multiple keys where one has a comment
1253: and other following keys do not.
1254: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>,
1.14 dtucker 1255: <a href="https://man.openbsd.org/sftp.1">sftp(1)</a>:
1.13 dtucker 1256: adjust ftruncate() logic to handle servers that
1257: reorder requests. Previously, if the server reordered requests then
1258: the resultant file would be erroneously truncated.
1259: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1260: don't incorrectly disable hostname canonicalization when
1.16 jsg 1261: CanonicalizeHostname=yes and ProxyJump was explicitly set to
1.13 dtucker 1262: "none".
1263: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
1264: when copying local to remote, check that the source file

1558: <section id=sourcecode>
1559: <h3>Notes about the source code</h3>
1560: <p>
1561: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1562: This file contains everything you need except for the kernel sources,
1563: which are in a separate archive.
1564: To extract:
1565: <blockquote><pre>
1566: # <kbd>mkdir -p /usr/src</kbd>
1567: # <kbd>cd /usr/src</kbd>
1568: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1569: </pre></blockquote>
1570: <p>
1571: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1572: This file contains all the kernel sources you need to rebuild kernels.
1573: To extract:
1574: <blockquote><pre>
1575: # <kbd>mkdir -p /usr/src/sys</kbd>
1576: # <kbd>cd /usr/src</kbd>
1577: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1578: </pre></blockquote>
1579: <p>
1580: Both of these trees are a regular CVS checkout. Using these trees it
1581: is possible to get a head-start on using the anoncvs servers as
1582: described <a href="anoncvs.html">here</a>.
1583: Using these files
1584: results in a much faster initial CVS update than you could expect from
1585: a fresh checkout of the full OpenBSD source tree.

1591: <h3>Ports Tree</h3>
1592: <p>
1593: A ports tree archive is also provided. To extract:
1594: <blockquote><pre>
1595: # <kbd>cd /usr</kbd>
1596: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1597: </pre></blockquote>
1598: <p>
1599: Go read the <a href="faq/ports/index.html">ports</a> page
1600: if you know nothing about ports
1601: at this point. This text is not a manual of how to use ports.
1602: Rather, it is a set of notes meant to kickstart the user on the
1603: OpenBSD ports system.
1604: <p>
1605: The <i>ports/</i> directory represents a CVS checkout of our ports.
1606: As with our complete source tree, our ports tree is available via
1607: <a href="anoncvs.html">AnonCVS</a>.
1608: So, in order to keep up to date with the -stable branch, you must make
1609: the <i>ports/</i> tree available on a read-write medium and update the tree
1610: with a command like:
1611: <blockquote><pre>
1612: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1613: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1614: </pre></blockquote>
1615: <p>
1616: [Of course, you must replace the server name here with a nearby anoncvs
1617: server.]
1618: <p>
1619: Note that most ports are available as packages on our mirrors. Updated
1620: ports for the 7.4 release will be made available if problems arise.
1621: <p>
1622: If you're interested in seeing a port added, would like to help out, or just
1623: would like to know more, the mailing list
1624: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
