1.1 benno 461: </ul>
462:
463: <li>Security improvements:
464: <ul>
1.13 benno 465: <li>Add Synthetic Memory Protections. These provide
466: <ul>
467: <li>Immutable memory mappings whose permissions and size cannot be
468: changed anymore. A new system call <a
469: href="https://man.openbsd.org/mimmutable.2">mimmutable(2)</a> enables
470: this feature.
471: <li>Execute-Only permission on memory mappings. This uses hardware
472: support where possible and emulation where the hardware does not have
1.16 jsg 473: separate execute only features.
1.13 benno 474: <li>Stack permission on mappings: On every system call the stack
475: pointer is checked. It must point to a mapping that has MAP_STACK
476: permissions.
477: <li>Pinning of syscall entry to a unique specific memory regions from
478: which system calls can be made.
479: </ul><br>
480: The execute-only mappings are active on arm64, risc-v, hppa,
481: aarch64, mips64, sparc64, amd64, mips, and power-pc platforms.
482: <!-- XXX xonly checks on copyin(9) are not described yet -->
483:
484: <li>Implemented a --executable-only option in <a href="https://man.openbsd.org/ld.bfd.1">ld.bfd(1)</a>.
485:
486: <li>Added <a href="https://man.openbsd.org/execve.2">execve(2)</a>
487: violations of <a
488: href="https://man.openbsd.org/pinsyscall.2">pinsyscall(2)</a> policy
489: to the daily mail, available by setting rc.conf.local(5)
490: accounting=YES.
491: <li>Added retguard to amd64 syscalls.
492:
493: <li>Randomly relink and install <a
494: href="https://man.openbsd.org/sshd.8">sshd(8)</a> on boot, resulting
495: in a sshd with unknown address layout after every reboot.
496:
497: <li>Add another mitigation against classic BROP on systems without
498: execute-only mmu hardware-enforcement. A range-checking wrapper in
499: front of copyin() and copyinstr() ensures the userland source address
500: doesn't overlap the main program text and other text segments, thereby
501: making this address ranges unreadable to the kernel. No programs have
502: been discovered which require reading their own text segments with a
503: system call.
1.1 benno 504: </ul>
505:
506: <li>Changes in the network stack:
507: <ul>
1.13 benno 508:
509: <li>Used stoeplitz (symmetric Toeplitz hash algorithm) to generate a
510: hash/flowid for <a href="https://man.openbsd.org/pf.4">pf(4)</a> state
511: keys. With this change, pf will hash traffic the same way that
512: hardware using a stoeplitz key will hash incoming traffic on rings.
513: stoeplitz is also used by the tcp stack to generate a flow id, which
514: is used to pick which transmit ring is used on nics with multiple
515: queues too. using the same algorithm throughout the stack encourages
516: affinity of packets to rings and softnet threads the whole way
517: through.
518:
519: <li>Prevented possible kernel crashes by dropping TCP packets with
520: destination port 0 in <a href="https://man.openbsd.org/pf.4">pf(4)</a>
521: and the stack.
522:
523: <li>Fixed a endian swap bug causing problems with <a
524: href="https://man.openbsd.org/vlan.4">vlans(4)</a> on <a
525: href="https://man.openbsd.org/em.4">em(4)</a> sparc64 systems.
526: <li>Denied "pipex no" tunnel setting for <a
527: href="https://man.openbsd.org/pppx.4">pppx(4)</a> interfaces.
528: <li>Fixed a panic in <a
529: href="https://man.openbsd.org/pfsync.4">pfsync(4)</a> when there are
530: no data ready for bulk transfer.
531: <li>Turned off TCP Segmentation Offload (TSO) if interface is added
532: to layer 2 devices.
533: <li>Improved <a href="https://man.openbsd.org/vnet.4">vnet(4)</a>
534: to work better in busy conditions.
535: <li>Added a <a href="https://man.openbsd.org/bpf.4">bpf(4)</a> timeout
536: (BIOCSWTIMEOUT) between capturing a packet and making the buffer
537: readable, preventing for example <a
538: href="https://man.openbsd.org/pflogd.8">pflogd(8)</a> waking every
539: half second even if there is nothing to read. By default this buffer
540: is infinite and must be filled to become readable.
541: <li>Avoided enabling TSO on interfaces which are already attached to a bridge.
542:
543: </ul>
1.1 benno 544:
545: <li>Routing daemons and other userland network improvements:
546: <ul>
547: <li>IPsec support was improved:
548: <ul>
1.13 benno 549: <li>Added <a href="https://man.openbsd.org/iked.8">iked(8)</a>
550: support for configuring multiple name servers.
551: <li>Synced proc.c from <a
552: href="https://man.openbsd.org/vmd.8">vmd(8)</a> to <a
553: href="https://man.openbsd.org/iked.8">iked(8)</a> to enabled fork +
554: exec for all processes. This gives each process a fresh and unique
555: address space to further improve randomization of ASLR and stack
556: protector.
557: </ul>
558:
559: <li>In <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>, <a
560: href="https://man.openbsd.org/bgpctl.8">bgpctl(8)</a> and <a
561: href="https://man.openbsd.org/bgplgd.8">bgplgd(8)</a>:
562: <ul>
563: <li>Improved performance by optimising the output filters
1.16 jsg 564: <li>Add Autonomous System Provider Authorization (ASPA) validation
1.13 benno 565: based on draft-ietf-sidrops-aspa-verification-12
566: <li>Introduce avs (ASPA validation state) filter and bgpctl
567: filter argument
568: <li>Add ASPA support for the RTR protocol based on
569: draft-ietf-sidrops-8210bis-10
570: <li>Improve open policy (RFC 9234) support and enable the capability
571: automatically if a role is specified for the peer
572: <li>Introduce a per neighbor 'role' configuration option to specify
573: the session role used by ASPA verification and the open policy
574: capability. The 'announce policy' statement was simplified at
575: the same time.
576: <li>Improve startup behaviour by introducing a small delay before
577: opening the connection to a new peer
578: <li>Support for aspa-set table config which can be provided by
579: <a
580: href="https://man.openbsd.org/rpki-client.8">rpki-client(8)</a>
581: <li>Make it possible to filter the RIB by invalid and leaked prefixes
582: in bgpctl and bgplgd
583: <li>Add OpenMetrics output to bgpctl for various BGP statistics and
584: add /metrics endpoint to bgplgd
585: <li>Fix of incorrect length checks that allowed an out-of-bounds
586: read in bgpd.
1.1 benno 587: </ul>
588: <li><a href="https://man.openbsd.org/rpki-client.8">rpki-client(8)</a> saw some changes:
589: <ul>
1.13 benno 590: <li>Add a new '-H' command line option to create a shortlist of
591: repositories to synchronize to. For example, when invoking
592: "rpki-client -H rpki.ripe.net -H chloe.sobornost.net", the utility
593: will not connect to any other hosts other than the two specified
594: through the -H option.
595: <li>Add support for validating Geofeed (RFC 9092) authenticators. To
596: see an example download https://sobornost.net/geofeed.csv and run
597: "rpki-client -f geofeed.csv"
598: <li>Add support for validating Trust Anchor Key (TAK) objects. TAK
599: objects can be used to produce new Trust Anchor Locators (TALs) signed
600: by and verified against the previous Trust Anchor. See
601: draft-ietf-sidrops-signed-tal for the full specification.
602: <li>Log lines related to RRDP/HTTPS connection problems now include the
603: IP address of the problematic endpoint (in brackets).
604: <li>Improve the error message when an invalid filename is encountered
605: in the rpkiManifest field in the Subject Access Information (SIA)
606: extension.
607: <li>Emit a warning when unexpected X.509 extensions are encountered.
608: <li>Restrict the ROA ipAddrBlocks field to only allow two
609: ROAIPAddressFamily structures (one per address family). See
610: draft-ietf-sidrops-rfc6482bis.
611: <li>Check the absence of the Path Length constraint in the Basic
612: Constraints extension.
613: <li>Restrict the SIA extension to only allow the signedObject and
614: rpkiNotify accessMethods.
615: <li>Check that the Signed Object access method is present in ROA, MFT,
616: ASPA, TAK, and GBR End-Entity certificates.
617: <li>In addition to the 'rsync://' scheme, also permit other schemes
618: (such as 'https://') in the SIA signedObject access method.
619: <li>Check that the KeyUsage extension is set to nothing but
620: digitalSignature on End-Entity certificates.
1.16 jsg 621: <li>Check that the KeyUsage extension is set to nothing but keyCertSign
1.13 benno 622: and CRLSign on CA certificates.
623: <li>Check that the ExtendedKeyUsage extension is absent on CA
624: certificates.
625: <li>Fix a bug in the handling of the port of http_proxy.
626: <li>The '-r' command line option has been deprecated.
627: <li>Filemode (-f) output is now presented as a text based table.
628: <li>The 'expires' key in the JSON/CSV/OpenBGPD output formats is now
629: calculated with more accuracy. The calculation takes into account the
630: nextUpdate value of all intermediate CRLs in the signature path
631: towards the trust anchor, in addition to the expiry moment of the
632: leaf-CRL and CAs.
633: <li>Handling of CRLs and Manifests in the face of inconsistent RRDP delta
634: publications has been improved. A copy of an alternative version of
635: the applicable CRL is kept in the staging area of the cache directory,
636: in order to increase the potential for establishing a complete
637: publication point, in cases where a single publication point update
638: was smeared across multiple RRDP delta files.
639: <li>The OpenBGPD configuration output now includes validated Autonomous
640: System Provider Authorization (ASPA) payloads as an 'aspa-set {}'
641: configuration block.
642: <li>When rpki-client is invoked with increased verbosity ('-v'), the
643: current RRDP Serial & Session ID are shown to aid debugging.
644: <li>Self-signed X.509 certificates (such as Trust Anchor certificates)
645: now are considered invalid if they contain an X.509
646: AuthorityInfoAccess extension.
647: <li>Signed Objects where the CMS signing-time attribute contains a
648: timestamp later then the X.509 certificate's notAfter timestamp are
649: considered invalid.
650: <li>Manifests where the CMS signing-time attribute contains a timestamp
651: later then the Manifest eContent nextUpdate timestamp are considered
652: invalid.
653: <li>Any objects whose CRL Distribution Points extension contains a
654: CRLIssuer, CRL Reasons, or nameRelativeToCRLIssuer field are
655: considered invalid in accordance with RFC 6487 section 4.8.6.
656: <li>For every X.509 certificate the SHA-1 of the Subject Public Key is
657: calculated and compared to the Subject Key Identifier (SKI), if a
658: mismatch is found the certificate is not trusted.
659: <li>Require the outside-TBS signature OID for every X.509 intermediate
660: CA certificate and CRL to be sha256WithRSAEncryption.
661: <li>Require the RSA key pair modulus and public exponent parameters to
662: strictly conform to the RFC 7935 profile.
663: <li>Ensure there is no trailing garbage present in Signed Objects beyond
664: the self-embedded length field.
665: <li>Require RRDP Session IDs to strictly be version 4 UUIDs.
666: <li>When decoding and validating an individual RPKI file using filemode
667: (rpki-client -f file), display the signature path towards the trust
668: anchor, and the timestamp when the signature path will expire.
669: <li>When decoding and validating an individual RPKI file using filemode
670: (rpki-client -f file), display the optional CMS signing-time, and
671: non-optional X.509 notBefore, and X.509 notAfter timestamps.

1.1 benno 807: </ul>
808: </ul>
809:
1.14 benno 810: <li>OpenSSH 9.3 and OpenSSH 9.2<br>
811: This release of OpenBSD includes the changes made to OpenSSH since release 9.1:
1.1 benno 812: <ul>
813: <li>Security
814: <ul>
1.14 benno 815: <li>ssh-add(1): when adding smartcard keys to ssh-agent(1) with the
816: per-hop destination constraints (ssh-add -h ...) added in OpenSSH
817: 8.9, a logic error prevented the constraints from being
818: communicated to the agent. This resulted in the keys being added
819: without constraints. The common cases of non-smartcard keys and
820: keys without destination constraints are unaffected. This problem
821: was reported by Luci Stanescu.
822: <li>ssh(1): Portable OpenSSH provides an implementation of the
823: getrrsetbyname(3) function if the standard library does not
824: provide it, for use by the VerifyHostKeyDNS feature. A
825: specifically crafted DNS response could cause this function to
826: perform an out-of-bounds read of adjacent stack data, but this
827: condition does not appear to be exploitable beyond denial-of-
828: service to the ssh(1) client.<br>
829: The getrrsetbyname(3) replacement is only included if the system's
830: standard library lacks this function and portable OpenSSH was not
831: compiled with the ldns library (--with-ldns). getrrsetbyname(3) is
832: only invoked if using VerifyHostKeyDNS to fetch SSHFP records. This
833: problem was found by the Coverity static analyzer.
834: <li>sshd(8): fix a pre-authentication double-free memory fault
835: introduced in OpenSSH 9.1. This is not believed to be exploitable,
836: and it occurs in the unprivileged pre-auth process that is
837: subject to chroot(2) and is further sandboxed on most major
838: platforms.
839: <li>ssh(8): in OpenSSH releases after 8.7, the PermitRemoteOpen option
840: would ignore its first argument unless it was one of the special
841: keywords "any" or "none", causing the permission list to fail open
842: if only one permission was specified. bz3515
843: <li>ssh(1): if the CanonicalizeHostname and CanonicalizePermittedCNAMEs
844: options were enabled, and the system/libc resolver did not check
845: that names in DNS responses were valid, then use of these options
846: could allow an attacker with control of DNS to include invalid
847: characters (possibly including wildcards) in names added to
848: known_hosts files when they were updated. These names would still
849: have to match the CanonicalizePermittedCNAMEs allow-list, so
850: practical exploitation appears unlikely.
851: </ul>
1.1 benno 852: <li>Potentially-incompatible changes
1.14 benno 853: <ul>
854: <li>ssh(1): add a new EnableEscapeCommandline ssh_config(5) option that
855: controls whether the client-side ~C escape sequence that provides a
856: command-line is available. Among other things, the ~C command-line
857: could be used to add additional port-forwards at runtime.<br>
858: This option defaults to "no", disabling the ~C command-line that
859: was previously enabled by default. Turning off the command-line
860: allows platforms that support sandboxing of the ssh(1) client
861: (currently only OpenBSD) to use a stricter default sandbox policy.
862: </ul>
863: <li>New features
864: <ul>
865: <li>ssh-keygen(1), ssh-keyscan(1): accept -Ohashalg=sha1|sha256 when
866: outputting SSHFP fingerprints to allow algorithm selection. bz3493
867: <li>sshd(8): add a `sshd -G` option that parses and prints the
868: effective configuration without attempting to load private keys
869: and perform other checks. This allows usage of the option before
870: keys have been generated and for configuration evaluation and
871: verification by unprivileged users.
872: <li>sshd(8): add support for channel inactivity timeouts via a new
873: sshd_config(5) ChannelTimeout directive. This allows channels that
874: have not seen traffic in a configurable interval to be
875: automatically closed. Different timeouts may be applied to session,
876: X11, agent and TCP forwarding channels.
877: <li>sshd(8): add a sshd_config UnusedConnectionTimeout option to
878: terminate client connections that have no open channels for a
879: length of time. This complements the ChannelTimeout option above.
880: <li>sshd(8): add a -V (version) option to sshd like the ssh client has.
881: <li>ssh(1): add a "Host" line to the output of ssh -G showing the
882: original hostname argument. bz3343
883: <li>scp(1), sftp(1): add a -X option to both scp(1) and sftp(1) to
884: allow control over some SFTP protocol parameters: the copy buffer
885: length and the number of in-flight requests, both of which are used
886: during upload/download. Previously these could be controlled in
887: sftp(1) only. This makes them available in both SFTP protocol
888: clients using the same option character sequence.
889: <li>ssh-keyscan(1): allow scanning of complete CIDR address ranges,
890: e.g. "ssh-keyscan 192.168.0.0/24". If a CIDR range is passed, then
891: it will be expanded to all possible addresses in the range
892: including the all-0s and all-1s addresses. bz#976
893: <li>ssh(1): support dynamic remote port forwarding in escape
894: command-line's -R processing. bz#3499
895: </ul>
1.1 benno 896: <li>Bugfixes
1.14 benno 897: <ul>
898: <li>scp(1), sftp(1): fix progressmeter corruption on wide displays;
899: bz3534
900: <li>ssh-add(1), ssh-keygen(1): use RSA/SHA256 when testing usability
901: of private keys as some systems are starting to disable RSA/SHA1
902: in libcrypto.
903: <li>sftp-server(8): fix a memory leak. GHPR363
1.16 jsg 904: <li>ssh(1), sshd(8), ssh-keyscan(1): remove vestigial protocol
1.14 benno 905: compatibility code and simplify what's left.
906: <li>Fix a number of low-impact Coverity static analysis findings.
907: These include several reported via bz2687
908: <li>ssh_config(5), sshd_config(5): mention that some options are not
909: first-match-wins.
910: <li>Rework logging for the regression tests. Regression tests will now
911: capture separate logs for each ssh and sshd invocation in a test.
912: <li>ssh(1): make `ssh -Q CASignatureAlgorithms` work as the manpage
913: says it should; bz3532.
914: <li>ssh(1): ensure that there is a terminating newline when adding a
915: new entry to known_hosts; bz3529
916: <li>ssh(1): when restoring non-blocking mode to stdio fds, restore
917: exactly the flags that ssh started with and don't just clobber them
918: with zero, as this could also remove the append flag from the set.
919: bz3523
920: <li>ssh(1): avoid printf("%s", NULL) if using UserKnownHostsFile=none
921: and a hostkey in one of the system known hosts file changes.
922: <li>scp(1): switch scp from using pipes to a socket-pair for
923: communication with its ssh sub-processes, matching how sftp(1)
924: operates.
925: <li>sshd(8): clear signal mask early in main(); sshd may have been
926: started with one or more signals masked (sigprocmask(2) is not
927: cleared on fork/exec) and this could interfere with various things,
928: e.g. the login grace timer. Execution environments that fail to
929: clear the signal mask before running sshd are clearly broken, but
930: apparently they do exist.
931: <li>ssh(1): warn if no host keys for hostbased auth can be loaded.
932: <li>sshd(8): Add server debugging for hostbased auth that is queued and
933: sent to the client after successful authentication, but also logged
934: to assist in diagnosis of HostbasedAuthentication problems. bz3507
935: <li>ssh(1): document use of the IdentityFile option as being usable to
936: list public keys as well as private keys. GHPR352
937: <li>sshd(8): check for and disallow MaxStartups values less than or
938: equal to zero during config parsing, rather than failing later at
939: runtime. bz3489
940: <li>ssh-keygen(1): fix parsing of hex cert expiry times specified on
941: the command-line when acting as a CA.
942: <li>scp(1): when scp(1) is using the SFTP protocol for transport (the
943: default), better match scp/rcp's handling of globs that don't match
944: the globbed characters but do match literally (e.g. trying to
945: transfer a file named "foo.[1]"). Previously scp(1) in SFTP mode
946: would not match these pathnames but legacy scp/rcp mode would.
947: bz3488
948: <li>ssh-agent(1): document the "-O no-restrict-websafe" command-line
949: option.
950: <li>ssh(1): honour user's umask(2) if it is more restrictive then the
951: ssh default (022).

1248: <section id=sourcecode>
1249: <h3>Notes about the source code</h3>
1250: <p>
1251: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1252: This file contains everything you need except for the kernel sources,
1253: which are in a separate archive.
1254: To extract:
1255: <blockquote><pre>
1256: # <kbd>mkdir -p /usr/src</kbd>
1257: # <kbd>cd /usr/src</kbd>
1258: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1259: </pre></blockquote>
1260: <p>
1261: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1262: This file contains all the kernel sources you need to rebuild kernels.
1263: To extract:
1264: <blockquote><pre>
1265: # <kbd>mkdir -p /usr/src/sys</kbd>
1266: # <kbd>cd /usr/src</kbd>
1267: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1268: </pre></blockquote>
1269: <p>
1270: Both of these trees are a regular CVS checkout. Using these trees it
1271: is possible to get a head-start on using the anoncvs servers as
1272: described <a href="anoncvs.html">here</a>.
1273: Using these files
1274: results in a much faster initial CVS update than you could expect from
1275: a fresh checkout of the full OpenBSD source tree.

1282: <p>
1283: A ports tree archive is also provided. To extract:
1284: <blockquote><pre>
1285: # <kbd>cd /usr</kbd>
1286: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1287: </pre></blockquote>
1288: <p>
1289: Go read the <a href="faq/ports/index.html">ports</a> page
1290: if you know nothing about ports
1291: at this point. This text is not a manual of how to use ports.
1292: Rather, it is a set of notes meant to kickstart the user on the
1293: OpenBSD ports system.
1294: <p>
1295: The <i>ports/</i> directory represents a CVS checkout of our ports.
1296: As with our complete source tree, our ports tree is available via
1297: <a href="anoncvs.html">AnonCVS</a>.
1298: So, in order to keep up to date with the -stable branch, you must make
1299: the <i>ports/</i> tree available on a read-write medium and update the tree
1300: with a command like:
1301: <blockquote><pre>
1302: # <kbd>cd /usr/ports</kbd>
1303: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_3</kbd>
1304: </pre></blockquote>
1305: <p>
1306: [Of course, you must replace the server name here with a nearby anoncvs
1307: server.]
1308: <p>
1309: Note that most ports are available as packages on our mirrors. Updated
1310: ports for the 7.3 release will be made available if problems arise.
1311: <p>
1312: If you're interested in seeing a port added, would like to help out, or just
1313: would like to know more, the mailing list
1314: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
