81: <li>...
82: </ul>
83:
84: <li>Various kernel improvements:
85: <ul>
1.13 benno 86:
1.21 ! benno 87:
! 88: <li>On arm64, avoid usin 1GB mappings for the identity map in the
! 89: early kernel bootstrap phase and when booting the secondary CPUs. This
! 90: avoids accidentally mapping memory regions that should not be mapped
! 91: (i.e. secure memory) as all mapped memory can be accessed
! 92: speculatively.
! 93:
! 94: <li>Added arm64 detection of EPAN feature bit. Enhanced Privileged Access Never
! 95: (EPAN) allows Privileged Access Never to be used with Execute-only mappings.
! 96:
1.13 benno 97: <li>Removed copystr(9) from public API.
98:
99: <li>Made the USB ports work after a suspend/resume cycle on the x13s.
100: <li>Set the arm64 default for the machdep.lidaction <a
101: href="https://man.openbsd.org/sysctl.8">sysctl(8)</a> to 1, making the
102: system suspend when the lid is closed. <a
103: href="https://man.openbsd.org/aplsmc.4">aplsmc(4)</a> provides support
104: for the lid position sensor.
105:
106: <li>Changed arm64 suspend idle loop from WFE to WFI, avoiding spurious
107: wakeups while other CPUs are still active.
108: <li>Added cursor back tab support to <a
109: href="https://man.openbsd.org/wscons.4">wscons(4)</a> VT100
110: emulation.<br>Added aixterm bright color sequences (SGR 90-97 and
111: 100-107).
112: <li>Added missing <a
113: href="https://man.openbsd.org/wscons.4">wscons(4)</a> bounds checks
114: when processing terminal escape sequences.
115: <li>Replaced broken UTF-8 logic in <a
116: href="https://man.openbsd.org/wscons.4">wscons(4)</a> with a better
117: one borrowed from Citrus.
118: <li>Added new <a href="https://man.openbsd.org/dt.4">dt(4)</a> ioctl
119: DTIOCARGS to get the type of probe arguments.
120: <li>Added a priority queue to <a
121: href="https://man.openbsd.org/clockintr.9">clockintr(9)</a>.
122:
1.1 benno 123: </ul>
124:
125: <li>SMP Improvements
126: <ul>
1.13 benno 127:
128: <li>Made <a href="https://man.openbsd.org/tun.4">tun(4)</a> and <a
129: href="https://man.openbsd.org/tap.4">tap(4)</a> event filters MP-safe.

167: href="https://man.openbsd.org/vmd.8">vmd(8)</a> guests with SeaBIOS.
168: When a vm initializes memory ranges, we now track what each range
169: represents. This information can be used to supply the e820 memory map
170: to SeaBIOS via the fw_cfg interface allowing it to properly
171: communicate memory ranges to a guest operating system. With this
172: special cases in ports can be removed.
173:

180: identification to i386 and amd64.
181:
182: <li>Changed <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> to
183: only open /dev/vmm once, having the parent process send the fd to the
184: vmm child process.
185: <li>Restricted <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> exposed cpuid extended feature flags.
186: <li>Adjusted <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> error paths to avoid removal of configuration-defined (known) VMs on error.
187: <li>Stopped being paranoid about hypervisor correct PKU handling.<br>
188: Added saving and restoring guest PKRU to <a
189: href="https://man.openbsd.org/vmm.4">vmm(4)</a>. Expose the PKU cpuid
190: bit to the guest if in use on the host.

1.1 benno 419: </ul>
420:
421: <li>Installer, upgrade and bootloader improvements:
422: <ul>
1.17 kn 423: <li>Made installer answers <code>!</code> and <code>(S)hell</code> drop into a <a
1.13 benno 424: href="https://man.openbsd.org/ksh.1">ksh(1)</a> environment rather
425: than the more limited <a href="https://man.openbsd.org/sh.1">sh(1)</a>.
1.18 kn 426: <li>Added support for configuring interfaces by lladdr (MAC).
1.13 benno 427: <li>Made the installer skip interface configuration questions when no interfaces are available.
428: <li>Fixed resizing partitions on an auto-allocated disk that had a boot partition.
429: <li>Stopped the installer from asking to initialize disks that have
430: <a href="https://man.openbsd.org/softraid.4">softraid(4)</a> chunks.
431: <li>Made efiboot fdt support device trees with NOPs in them (like the kernel version).
432: <li>Improved the default choice for the installer's install media
433: disk question to show the first disk (a) not the root disk and (b) not
434: a disk with softraid chunks (hosting the root disk, for example).
435: <li>Stopped offering WEP in the installer if not supported.
1.17 kn 436: <li>Fixed lock file error on installer exit/abort.

440: <a href="https://man.openbsd.org/softraid.4">softraid(4)</a>. keydisks.
441: <li>Fixed passing explicit stages files to
442: <a href="https://man.openbsd.org/installboot.8">installboot(8)</a>.
1.13 benno 443:
444: <!-- architecture specific -->
1.18 kn 445: <li>Made the installer stop printing MD post installation instructions on upgrades.

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

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

1265: <section id=sourcecode>
1266: <h3>Notes about the source code</h3>
1267: <p>
1268: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1269: This file contains everything you need except for the kernel sources,
1270: which are in a separate archive.
1271: To extract:
1272: <blockquote><pre>
1273: # <kbd>mkdir -p /usr/src</kbd>
1274: # <kbd>cd /usr/src</kbd>
1275: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1276: </pre></blockquote>
1277: <p>
1278: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1279: This file contains all the kernel sources you need to rebuild kernels.
1280: To extract:
1281: <blockquote><pre>
1282: # <kbd>mkdir -p /usr/src/sys</kbd>
1283: # <kbd>cd /usr/src</kbd>
1284: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1285: </pre></blockquote>
1286: <p>
1287: Both of these trees are a regular CVS checkout. Using these trees it
1288: is possible to get a head-start on using the anoncvs servers as
1289: described <a href="anoncvs.html">here</a>.
1290: Using these files
1291: results in a much faster initial CVS update than you could expect from
1292: a fresh checkout of the full OpenBSD source tree.

1300: A ports tree archive is also provided. To extract:
1301: <blockquote><pre>
1302: # <kbd>cd /usr</kbd>
1303: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1304: </pre></blockquote>
1305: <p>
1306: Go read the <a href="faq/ports/index.html">ports</a> page
1307: if you know nothing about ports
1308: at this point. This text is not a manual of how to use ports.
1309: Rather, it is a set of notes meant to kickstart the user on the
1310: OpenBSD ports system.
1311: <p>
1312: The <i>ports/</i> directory represents a CVS checkout of our ports.
1313: As with our complete source tree, our ports tree is available via
1314: <a href="anoncvs.html">AnonCVS</a>.
1315: So, in order to keep up to date with the -stable branch, you must make
1316: the <i>ports/</i> tree available on a read-write medium and update the tree
1317: with a command like:
1318: <blockquote><pre>
1319: # <kbd>cd /usr/ports</kbd>
1320: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_3</kbd>
1321: </pre></blockquote>
1322: <p>
1323: [Of course, you must replace the server name here with a nearby anoncvs
1324: server.]
1325: <p>
1326: Note that most ports are available as packages on our mirrors. Updated
1327: ports for the 7.3 release will be made available if problems arise.
1328: <p>
1329: If you're interested in seeing a port added, would like to help out, or just
1330: would like to know more, the mailing list
1331: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
