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820: withdrawn, and published again.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

1.1 deraadt 1097: <ul>
1.12 dtucker 1098: <li>Potentially incompatible changes
1.1 deraadt 1099: <ul>
1.12 dtucker 1100: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1101: generate Ed25519 keys by default. Ed25519 public keys
1102: are very convenient due to their small size. Ed25519 keys are
1103: specified in RFC 8709 and OpenSSH has supported them since version 6.5
1104: (January 2014).
1105: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1106: the Subsystem directive now accurately preserves quoting of
1107: subsystem commands and arguments. This may change behaviour for exotic
1108: configurations, but the most common subsystem configuration
1109: (sftp-server) is unlikely to be affected.
1.13 dtucker 1110: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
1111: PKCS#11 modules must now be specified by their full
1112: paths. Previously dlopen(3) could search for them in system
1113: library directories.
1.1 deraadt 1114: </ul>
1.12 dtucker 1115: <li>New features
1.1 deraadt 1116: <ul>
1.12 dtucker 1117: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1118: add keystroke timing obfuscation to the client. This attempts
1119: to hide inter-keystroke timings by sending interactive traffic at
1120: fixed intervals (default: every 20ms) when there is only a small
1121: amount of data being sent. It also sends fake "chaff" keystrokes for
1122: a random interval after the last real keystroke. These are
1123: controlled by a new ssh_config ObscureKeystrokeTiming keyword.
1124: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
1125: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1126: Introduce a transport-level ping facility. This adds
1127: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
1128: implement a ping capability. These messages use numbers in the "local
1129: extensions" number space and are advertised using a "ping@openssh.com"
1130: ext-info message with a string version number of "0".
1.13 dtucker 1131: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1132: allow override of Subsystem directives in sshd Match blocks.
1133: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1134: allow forwarding Unix Domain sockets via ssh -W.
1135: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1136: add support for configuration tags to ssh(1).
1137: This adds a ssh_config(5) "Tag" directive and corresponding
1138: "Match tag" predicate that may be used to select blocks of
1139: configuration similar to the pf.conf(5) keywords of the same
1140: name.
1141: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1142: add a "match localnetwork" predicate. This allows matching
1143: on the addresses of available network interfaces and may be used to
1144: vary the effective client configuration based on network location.
1145: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
1146: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
1147: <a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1148: infrastructure support for KRL
1149: extensions. This defines wire formats for optional KRL extensions
1150: and implements parsing of the new submessages. No actual extensions
1151: are supported at this point.
1152: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1153: AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
1154: accept two additional %-expansion sequences: %D which expands to
1155: the routing domain of the connected session and %C which expands
1156: to the addresses and port numbers for the source and destination
1157: of the connection.
1158: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1159: increase the default work factor (rounds) for the
1160: bcrypt KDF used to derive symmetric encryption keys for passphrase
1161: protected key files by 50%.
1.1 deraadt 1162: </ul>
1163: <li>Bugfixes
1164: <ul>
1.12 dtucker 1165: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
1166: fix scp in SFTP mode recursive upload and download of
1167: directories that contain symlinks to other directories. In scp mode,
1168: the links would be followed, but in SFTP mode they were not.
1169: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1170: handle cr+lf (instead of just cr) line endings in
1171: sshsig signature files.
1172: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1173: interactive mode for ControlPersist sessions if they
1174: originally requested a tty.
1175: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1176: make PerSourceMaxStartups first-match-wins
1177: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1178: limit artificial login delay to a reasonable maximum (5s)
1179: and don't delay at all for the "none" authentication mechanism.
1.13 dtucker 1180: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1181: Log errors in kex_exchange_identification() with level
1.12 dtucker 1182: verbose instead of error to reduce preauth log spam. All of those
1183: get logged with a more generic error message by sshpkt_fatal().
1184: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1185: correct math for ClientAliveInterval that caused the probes
1186: to be sent less frequently than configured.
1.13 dtucker 1187: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
1188: improve isolation between loaded PKCS#11 modules
1189: by running separate ssh-pkcs11-helpers for each loaded provider.
1190: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1191: make -f (fork after authentication) work correctly with
1192: multiplexed connections, including ControlPersist.
1193: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1194: make ConnectTimeout apply to multiplexing sockets and not
1195: just to network connections.
1196: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
1197: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1198: improve defences against invalid PKCS#11
1199: modules being loaded by checking that the requested module
1200: contains the required symbol before loading it.
1201: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
1202: fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand
1203: appears before it in sshd_config. Since OpenSSH 8.7 the
1204: AuthorizedPrincipalsCommand directive was incorrectly ignored in
1205: this situation.

1.16 jsg 1209: remove vestigial support for KRL
1.13 dtucker 1210: signatures When the KRL format was originally defined, it included
1211: support for signing of KRL objects. However, the code to sign KRLs
1.16 jsg 1212: and verify KRL signatures was never completed in OpenSSH. This
1.13 dtucker 1213: release removes the partially-implemented code to verify KRLs.
1214: All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in
1215: KRL files.
1216: <li>All: fix a number of memory leaks and unreachable/harmless integer
1217: overflows.
1218: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
1219: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1220: don't truncate strings logged from PKCS#11 modules
1221: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
1222: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1223: better validate CASignatureAlgorithms in
1224: ssh_config and sshd_config. Previously this directive would accept
1225: certificate algorithm names, but these were unusable in practice as
1226: OpenSSH does not support CA chains.
1227: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1228: make <code>ssh -Q CASignatureAlgorithms</code> only list signature
1229: algorithms that are valid for CA signing. Previous behaviour was
1230: to list all signing algorithms, including certificate algorithms.
1231: <li><a href="https://man.openbsd.org/ssh-keyscan.1">ssh-keyscan(1)</a>:
1232: gracefully handle systems where rlimits or the
1233: maximum number of open files is larger than INT_MAX
1234: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1235: fix "no comment" not showing on when running
1236: <code>ssh-keygen -l</code> on multiple keys where one has a comment
1237: and other following keys do not.
1238: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>,
1.14 dtucker 1239: <a href="https://man.openbsd.org/sftp.1">sftp(1)</a>:
1.13 dtucker 1240: adjust ftruncate() logic to handle servers that
1241: reorder requests. Previously, if the server reordered requests then
1242: the resultant file would be erroneously truncated.
1243: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1244: don't incorrectly disable hostname canonicalization when
1.16 jsg 1245: CanonicalizeHostname=yes and ProxyJump was explicitly set to
1.13 dtucker 1246: "none".
1247: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
1248: when copying local to remote, check that the source file

1542: <section id=sourcecode>
1543: <h3>Notes about the source code</h3>
1544: <p>
1545: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1546: This file contains everything you need except for the kernel sources,
1547: which are in a separate archive.
1548: To extract:
1549: <blockquote><pre>
1550: # <kbd>mkdir -p /usr/src</kbd>
1551: # <kbd>cd /usr/src</kbd>
1552: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1553: </pre></blockquote>
1554: <p>
1555: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1556: This file contains all the kernel sources you need to rebuild kernels.
1557: To extract:
1558: <blockquote><pre>
1559: # <kbd>mkdir -p /usr/src/sys</kbd>
1560: # <kbd>cd /usr/src</kbd>
1561: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1562: </pre></blockquote>
1563: <p>
1564: Both of these trees are a regular CVS checkout. Using these trees it
1565: is possible to get a head-start on using the anoncvs servers as
1566: described <a href="anoncvs.html">here</a>.
1567: Using these files
1568: results in a much faster initial CVS update than you could expect from
1569: a fresh checkout of the full OpenBSD source tree.

1578: <blockquote><pre>
1579: # <kbd>cd /usr</kbd>
1580: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1581: </pre></blockquote>
1582: <p>
1583: Go read the <a href="faq/ports/index.html">ports</a> page
1584: if you know nothing about ports
1585: at this point. This text is not a manual of how to use ports.
1586: Rather, it is a set of notes meant to kickstart the user on the
1587: OpenBSD ports system.
1588: <p>
1589: The <i>ports/</i> directory represents a CVS checkout of our ports.
1590: As with our complete source tree, our ports tree is available via
1591: <a href="anoncvs.html">AnonCVS</a>.
1592: So, in order to keep up to date with the -stable branch, you must make
1593: the <i>ports/</i> tree available on a read-write medium and update the tree
1594: with a command like:
1595: <blockquote><pre>
1596: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1597: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1598: </pre></blockquote>
1599: <p>
1600: [Of course, you must replace the server name here with a nearby anoncvs
1601: server.]
1602: <p>
1603: Note that most ports are available as packages on our mirrors. Updated
1604: ports for the 7.4 release will be made available if problems arise.
1605: <p>
1606: If you're interested in seeing a port added, would like to help out, or just
1607: would like to know more, the mailing list
1608: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
