71: <h3>What's New</h3>
72: <p>
73: This is a partial list of new features and systems included in OpenBSD 7.3.
74: For a comprehensive list, see the <a href="plus73.html">changelog</a> leading
75: to 7.3.
76:
77: <ul>
78:
79: <li>New/extended platforms:
80: <ul>
81: <li>...
82: </ul>
83:
84: <li>Various kernel improvements:
85: <ul>
1.22 benno 86: <li>Added support for the Rockchip RK3568 processor.
1.30 jsg 87: <li>Added <a href="https://man.openbsd.org/waitid.2">waitid(2)</a>,
88: wait for process state change.
89: <li>Added <a href="https://man.openbsd.org/pinsyscall.2">pinsyscall(2)</a>,
90: specify the call stub for a specific system call.
91: <li>Added <a href="https://man.openbsd.org/getthrname.2">getthrname(2)</a> and
92: <a href="https://man.openbsd.org/setthrname.2">setthrname(2)</a>,
93: get or set thread name.
1.22 benno 94: <li>Introduced <a
95: href="https://man.openbsd.org/clockintr.9">clockintr(9)</a>, a
1.31 jsg 96: machine-independent clock interrupt scheduler. Switched all
1.22 benno 97: architectures to use this new kernel subsystem.
98: <li>Introduced a new kern.autoconf_serial <a
99: href="https://man.openbsd.org/sysctl.8">sysctl(8)</a> that can be used
100: by userland to monitor state changes of the kernel device tree.
101: <li>Fixed <a href="https://man.openbsd.org/pmap.9">pmap(9)</a> bugs
102: involving entering an executable mapping for a page before
103: synchronizing the data and instruction cache on arm64 and riscv64.
104: <li>Add detection for Spectre-BHB Branch History Injection
105: vulnerability related CLRBHB, ECBHB and CSV2_3/HCXT feature bits.
106: <li>Add <a
107: href="https://man.openbsd.org/getnsecruntime.9">getnsecruntime(9)</a>
108: to the kernel timecounting API. Together with getbinruntime(), it
109: provides a fast, monotonic clock that only advances while the system
110: is not suspended.
1.24 jsg 111: <li>Prevent detaching ("bioctl -d detach") of a boot volume on a RAID managed by <a
1.22 benno 112: href="https://man.openbsd.org/bioctl.8">bioctl(8)</a>.
113: <li>Added WTRAPPED option for <a
114: href="https://man.openbsd.org/waitid.2">waitid(2)</a> to control
115: whether CLD_TRAPPED state changes, i.e., ptrace(2) on a process, are reported.
1.24 jsg 116: <li>On arm64, avoid using 1GB mappings for the identity map in the
1.21 benno 117: early kernel bootstrap phase and when booting the secondary CPUs. This
118: avoids accidentally mapping memory regions that should not be mapped
119: (i.e. secure memory) as all mapped memory can be accessed
120: speculatively.
121: <li>Added arm64 detection of EPAN feature bit. Enhanced Privileged Access Never
122: (EPAN) allows Privileged Access Never to be used with Execute-only mappings.
1.13 benno 123: <li>Removed copystr(9) from public API.
124: <li>Made the USB ports work after a suspend/resume cycle on the x13s.
1.22 benno 125: <li>On arm64, add a machdep.lidaction <a
126: href="https://man.openbsd.org/sysctl.8">sysctl(8)</a> for <a
127: href="https://man.openbsd.org/aplsmc.4">aplsmc(4)</a> Apple Silicon
128: laptops.<br>
129: The arm64 default for the machdep.lidaction is 1, making the
1.13 benno 130: system suspend when the lid is closed. <a
131: href="https://man.openbsd.org/aplsmc.4">aplsmc(4)</a> provides support
132: for the lid position sensor.
1.22 benno 133: <li>Disable the screen backlight with <a
134: href="https://man.openbsd.org/aplsmc.4">aplsmc(4)</a> on Apple Silicon
135: laptops when the lid is closed.
1.13 benno 136: <li>Changed arm64 suspend idle loop from WFE to WFI, avoiding spurious
137: wakeups while other CPUs are still active.
138: <li>Added cursor back tab support to <a
139: href="https://man.openbsd.org/wscons.4">wscons(4)</a> VT100
140: emulation.<br>Added aixterm bright color sequences (SGR 90-97 and
141: 100-107).
142: <li>Added missing <a
143: href="https://man.openbsd.org/wscons.4">wscons(4)</a> bounds checks
144: when processing terminal escape sequences.
145: <li>Replaced broken UTF-8 logic in <a
146: href="https://man.openbsd.org/wscons.4">wscons(4)</a> with a better
147: one borrowed from Citrus.
148: <li>Added new <a href="https://man.openbsd.org/dt.4">dt(4)</a> ioctl
149: DTIOCARGS to get the type of probe arguments.
150: <li>Added a priority queue to <a
151: href="https://man.openbsd.org/clockintr.9">clockintr(9)</a>.

159: <li>Unlocked <a href="https://man.openbsd.org/sched_yield.2">sched_yield(2)</a>.
160: <li>Added support for per-cpu event counters, to be used for clock and
161: IPI counters where the event counted occurs across all CPUs in the
162: system.
163: <li>Moved <a href="https://man.openbsd.org/pf.4">pf(4)</a> purge
164: tasks out from under the kernel lock.

204: on Apple Silicon laptops and the Lenovo x13s.
1.22 benno 205:
206: <li>Added support for the backlight connector property to <a
207: href="https://man.openbsd.org/amdgpu.4">amdgpu(4)</a> as in <a
208: href="https://man.openbsd.org/inteldrm.4">inteldrm(4)</a>, making <a
209: href="https://man.openbsd.org/xbacklight.1">xbacklight(1)</a> work
210: when using the Xorg modesetting driver.
211:
1.1 benno 212: </ul>
213:
214: <li>VMM/VMD improvements
215: <ul>
1.22 benno 216: <li>Updated <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> to
217: allow guests to read MSR_HWCR and MSR_PSTATEDEF, which is necessary to
218: determine the TSC frequency on AMD families 17h and 19h.
219: <li>Allocated reference for vm and vcpu SLISTs in <a
220: href="https://man.openbsd.org/vmm.4">vmm(4)</a>, keeping vmm from
221: triggering excessive wakeup calls while iterating through the list of
222: vms while servicing an <a
223: href="https://man.openbsd.org/ioctl.2">ioctl(2)</a>.
224: <li>Set <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> RAX guest
225: register state based on VMCB.
226: <li>Removed locking in <a
227: href="https://man.openbsd.org/vmm.4">vmm(4)</a> vmm_intr_pending,
228: reducing slowdowns due to requests for a lock held while the VM is
229: running.
230: <li>Increased speed of delivery of interrupts to a running vcpu in <a
231: href="https://man.openbsd.org/vmm.4">vmm(4)</a>.
232: <li>Made <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> treat vcpu
233: lists as immutable, removing the need to reference count individual
234: vcpu objects and use a rwlock.
1.13 benno 235: <li>Implemented zero-copy operations on virtqueues in <a
236: href="https://man.openbsd.org/vmd.8">vmd(8)</a>.
237: <li>Provided a detailed e820 memory map when booting <a
238: href="https://man.openbsd.org/vmd.8">vmd(8)</a> guests with SeaBIOS.
239: When a vm initializes memory ranges, we now track what each range
240: represents. This information can be used to supply the e820 memory map
241: to SeaBIOS via the fw_cfg interface allowing it to properly
242: communicate memory ranges to a guest operating system. With this
243: special cases in ports can be removed.
244: <li>Added thread names to vm processes in <a
245: href="https://man.openbsd.org/vmd.8">vmd(8)</a>, visible in <a
246: href="https://man.openbsd.org/ps.1">ps(1)</a>.
247: <li>Hid the WAITPKG cpu feature from <a
248: href="https://man.openbsd.org/vmm.4">vmm(4)</a> guests, preventing
249: invalid instruction exceptions. Also added WAITPKG feature
250: identification to i386 and amd64.
251: <li>Changed <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> to
252: only open /dev/vmm once, having the parent process send the fd to the
253: vmm child process.
1.35 ! benno 254: <li>Restricted <a href="https://man.openbsd.org/vmm.4">vmm(4)</a>
! 255: exposed cpuid extended feature flags.
! 256: <li>Adjusted <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> error
! 257: paths to avoid removal of configuration-defined (known) VMs on error.
1.13 benno 258: <li>Stopped being paranoid about hypervisor correct PKU handling.<br>
259: Added saving and restoring guest PKRU to <a
260: href="https://man.openbsd.org/vmm.4">vmm(4)</a>. Expose the PKU cpuid
261: bit to the guest if in use on the host.
1.35 ! benno 262: <li>Made <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> scan the
! 263: PCI bus to determine bootorder strings.
1.1 benno 264: </ul>
265:

1.13 benno 275: <li>Added <a
276: href="https://man.openbsd.org/lastcomm.1">lastcomm(1)</a> reporting
277: for process kills due to <a
278: href="https://man.openbsd.org/execve.2">execve(2)</a> from non-pinned
279: syscall address
1.1 benno 280: </ul>
281:
282: <li>Various bugfixes and tweaks in userland:
283: <ul>
1.26 jsg 284: <li>Allow TZ to contain absolute paths starting with /usr/share/zoneinfo.

292: href="https://man.openbsd.org/rc.subr.8">rc.subr(8)</a>. The rc_exec
293: function should be used instead.
294: <li>Excluded /tmp/*.shm files from /tmp cleaning in <a
295: href="https://man.openbsd.org/daily.8">daily(8)</a>. Removing them
296: interferes with programs that use shared memory via <a
297: href="https://man.openbsd.org/shm_open.3">shm_open(3)</a>.
298: <li>Added zap-to-char and zap-up-to-char to <a
299: href="https://man.openbsd.org/mg.1">mg(1)</a>. Bound zap-to-char to
300: M-z.
301: <li>Added support to <a

310: <li>Fixed handling of escaped backslashes in <a
311: href="https://man.openbsd.org/vi.1">vi(1)</a> ex_range.
312: <li>Corrected <a href="https://man.openbsd.org/top.1">top(1)</a>
313: display of online CPUs which can change based on the <a
314: href="https://man.openbsd.org/sysctl.2">sysctl(2)</a> sysctl setting.
1.13 benno 315: <li>Added support for a personal <a
316: href="https://man.openbsd.org/units.1">units(1)</a> library by passing
317: -f multiple times.
318:
319: <li>Made <a href="https://man.openbsd.org/rc.8">rc(8)</a> reorder
320: libraries in parallel to <a
321: href="https://man.openbsd.org/netstart.8">netstart(8)</a>, as this
322: does not depend on network access.
1.22 benno 323: <li>Made <a href="https://man.openbsd.org/rc.8">rc(8)</a> print the
324: name of each library before relinking as a signal to the operator that
325: boot has not stalled.
326:
1.13 benno 327: <li>Implemented periodic display in <a
328: href="https://man.openbsd.org/iostat.8">iostat(8)</a>.
329:
330: <li>Changed <a href="https://man.openbsd.org/df.1">df(1)</a> to
331: round up fractional percentages.
332:
1.35 ! benno 333: <!-- audio -->
1.13 benno 334: <li>Added the <a
335: href="https://man.openbsd.org/audioctl.8">audioctl(8)</a> -w option to
336: display variables periodically.
337: <li>Added short options for <a
338: href="https://man.openbsd.org/timeout.1">timeout(1)</a> --foreground
339: and --preserve-status.<br>
340: Added signal as a full argument name for <a
341: href="https://man.openbsd.org/timeout.1">timeout(1)</a> -s.
342: <li>Fixed .wav files generated by <a
1.35 ! benno 343: href="https://man.openbsd.org/aucat.1">aucat(1)</a> by using extended
1.13 benno 344: header format.
1.35 ! benno 345:
! 346: <!-- disks ... -->
1.13 benno 347: <li>In <a
348: href="https://man.openbsd.org/disklabel.8">disklabel(8)</a>, use the
349: size of the largest chunk of free space, not the total of all such
350: chunks, when checking for sufficient space to add a partition.
1.35 ! benno 351: <li>Extended <a
! 352: href="https://man.openbsd.org/disklabel.8">disklabel(8)</a> template
! 353: parsing to allow "[mount point] *" as the specification for putting
! 354: the maximum available free space into a partition, and extended
! 355: command line parsing to allow "T-" as the specification to read the
! 356: template from stdin.
! 357:
1.13 benno 358: <li>Fixed unbounded variable expansion in <a
359: href="https://man.openbsd.org/pkg-config.1">pkg-config(1)</a>.
360: <li>Switched to use <a
361: href="https://man.openbsd.org/llvm-strip.1">llvm-strip(1)</a> on
362: architectures that use <a
363: href="https://man.openbsd.org/ld.lld.1">ld.lld(1)</a>.
1.35 ! benno 364:
1.13 benno 365:
1.1 benno 366: </ul>

701: Programmers can request non-immutable static data using the
702: "openbsd.mutable" section, or manually bring immutability to (page
703: aligned heap objects) using <a
704: href="https://man.openbsd.org/mimmutable.2">mimmutable(2)</a>.
705: <li>Some architectures now have non-readable code ("xonly"), both from
706: the perspective of userland reading its own memory, or the kernel
707: trying to read memory in a system call. Many sloppy practices in
708: userland code had to be repaired to allow this. The <a
709: href="https://man.openbsd.org/ld.lld.1">linker (ld.lld(1))</a> option
710: --execute-only is enabled by default. In order of development: arm64,
711: riscv64, hppa, amd64, powerpc64, powerpc (G5 only), octeon. sparc64
712: (sun4u only, unfinished).
713: <li>On all architectures which lack hardware-enforcement of xonly,
714: system calls are now prevented from reading (via <a
715: href="https://man.openbsd.org/copyin.9">copyin(9)</a>/copyinst)
716: inside the program's main text, ld.so text, sigtramp text, or libc.so
717: text.
718: <li>can still benefit from switching to --execute-only binaries if the
719: cpu generates different traps for instruction-fetch versus data-fetch.
720: The VM system will not allow memory to be read before it was executed
721: which is valuable together with library relinking. Architectures
722: switched over include loongson.
723: <li><a href="https://man.openbsd.org/ld.so.1">ld.so(1)</a> and crt0
724: register the location of the <a
725: href="https://man.openbsd.org/execve.2">execve(2)</a> stub with the
726: kernel using pinsyscall(2), after which the kernel only accepts an
727: execve call from that specific location.
1.13 benno 728: <li>Added <a href="https://man.openbsd.org/execve.2">execve(2)</a>
729: violations of <a
730: href="https://man.openbsd.org/pinsyscall.2">pinsyscall(2)</a> policy
731: to the daily mail, available by setting rc.conf.local(5)
732: accounting=YES.
1.23 benno 733: <li>Added retguard (consistency-check the return address on the
734: stack) to amd64 syscalls.
735: <li>sshd random relinking at boot: Randomly relink and install <a
736: href="https://man.openbsd.org/sshd.8">sshd(8)</a>, resulting
737: in a sshd binary with unknown address layout after every reboot.
1.13 benno 738: <li>Add another mitigation against classic BROP on systems without
739: execute-only mmu hardware-enforcement. A range-checking wrapper in
1.23 benno 740: front of <a href="https://man.openbsd.org/copyin.9">copyin(9)</a> and
1.33 tj 741: <a href="https://man.openbsd.org/copyinstr.9">copyinstr(9)</a> ensures
1.23 benno 742: the userland source address doesn't overlap the main program text and
743: other text segments, thereby making this address ranges unreadable to
744: the kernel. No programs have been discovered which require reading
745: their own text segments with a system call.
1.22 benno 746: <li>On arm64, introduce mitigation of the Spectre-BHB (Branch
747: History Injection) CPU vulnerability by using core-specific trampoline
748: vectors.
1.23 benno 749: <li>Enabled the arm64 Data Independent Timing (DIT) feature in both the kernel and
750: userland on CPUs that support it to mitigate timing side-channel
1.22 benno 751: attacks.
1.1 benno 752: </ul>
753:
754: <li>Changes in the network stack:
755: <ul>
1.13 benno 756:
1.24 jsg 757: <li>Made /dev/pf a clonable device to better track kernel resources
1.22 benno 758: used by processes.
759: <li>Modified TCP receive buffer size auto-scaling to use the smoothed
760: RTT (SRTT) instead of the timestamp option, which improves performance
761: on high latency networks if the timestamp option isn't available.
1.24 jsg 762: <li>Relaxed the requirement for multicast support of interfaces for
1.22 benno 763: configuring IPv6. This allows non-multicast interfaces such as
764: point-to-point interfaces and the NBMA / point-to-multipoint
765: interfaces like mpe(4), mgre(4) and wg(4) to work with IPv6.
766: <li>Use the new <a
767: href="https://man.openbsd.org/getnsecruntime.9">getnsecruntime(9)</a>
768: timer to check the TCP_KEEPALIVE timer only against the system
769: runtime, not the uptime. Prevents TCP connections to fail after
1.24 jsg 770: waking up from suspend.
1.13 benno 771: <li>Used stoeplitz (symmetric Toeplitz hash algorithm) to generate a
772: hash/flowid for <a href="https://man.openbsd.org/pf.4">pf(4)</a> state
773: keys. With this change, pf will hash traffic the same way that
774: hardware using a stoeplitz key will hash incoming traffic on rings.
1.27 jsg 775: stoeplitz is also used by the TCP stack to generate a flow id, which
1.13 benno 776: is used to pick which transmit ring is used on nics with multiple
777: queues too. using the same algorithm throughout the stack encourages
778: affinity of packets to rings and softnet threads the whole way
779: through.
780: <li>Prevented possible kernel crashes by dropping TCP packets with
781: destination port 0 in <a href="https://man.openbsd.org/pf.4">pf(4)</a>
782: and the stack.
1.33 tj 783: <li>Fixed an endian swap bug causing problems with <a
1.27 jsg 784: href="https://man.openbsd.org/vlan.4">vlan(4)</a> on <a
1.13 benno 785: href="https://man.openbsd.org/em.4">em(4)</a> sparc64 systems.
786: <li>Denied "pipex no" tunnel setting for <a
787: href="https://man.openbsd.org/pppx.4">pppx(4)</a> interfaces.
1.22 benno 788: <li>Fixed <a href="https://man.openbsd.org/pfsync.4">pfsync(4)</a>
789: crashing on pf_state_key removal.
1.13 benno 790: <li>Fixed a panic in <a
791: href="https://man.openbsd.org/pfsync.4">pfsync(4)</a> when there are
792: no data ready for bulk transfer.
793: <li>Turned off TCP Segmentation Offload (TSO) if interface is added
794: to layer 2 devices.
795: <li>Improved <a href="https://man.openbsd.org/vnet.4">vnet(4)</a>
796: to work better in busy conditions.
797: <li>Added a <a href="https://man.openbsd.org/bpf.4">bpf(4)</a> timeout
798: (BIOCSWTIMEOUT) between capturing a packet and making the buffer
799: readable, preventing for example <a
800: href="https://man.openbsd.org/pflogd.8">pflogd(8)</a> waking every
801: half second even if there is nothing to read. By default this buffer
802: is infinite and must be filled to become readable.
803: <li>Avoided enabling TSO on interfaces which are already attached to a bridge.
804: </ul>
1.1 benno 805:
806: <li>Routing daemons and other userland network improvements:
807: <ul>
808: <li>IPsec support was improved:
809: <ul>
1.13 benno 810: <li>Added <a href="https://man.openbsd.org/iked.8">iked(8)</a>
811: support for configuring multiple name servers.
812: <li>Synced proc.c from <a
813: href="https://man.openbsd.org/vmd.8">vmd(8)</a> to <a
814: href="https://man.openbsd.org/iked.8">iked(8)</a> to enabled fork +
815: exec for all processes. This gives each process a fresh and unique
816: address space to further improve randomization of ASLR and stack
817: protector.
818: </ul>
819:
820: <li>In <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>, <a
821: href="https://man.openbsd.org/bgpctl.8">bgpctl(8)</a> and <a
822: href="https://man.openbsd.org/bgplgd.8">bgplgd(8)</a>:
823: <ul>
824: <li>Improved performance by optimising the output filters
1.16 jsg 825: <li>Add Autonomous System Provider Authorization (ASPA) validation
1.13 benno 826: based on draft-ietf-sidrops-aspa-verification-12
827: <li>Introduce avs (ASPA validation state) filter and bgpctl
828: filter argument
829: <li>Add ASPA support for the RTR protocol based on
830: draft-ietf-sidrops-8210bis-10
831: <li>Improve open policy (RFC 9234) support and enable the capability
832: automatically if a role is specified for the peer
833: <li>Introduce a per neighbor 'role' configuration option to specify
834: the session role used by ASPA verification and the open policy
835: capability. The 'announce policy' statement was simplified at
836: the same time.
837: <li>Improve startup behaviour by introducing a small delay before
838: opening the connection to a new peer
839: <li>Support for aspa-set table config which can be provided by
840: <a
841: href="https://man.openbsd.org/rpki-client.8">rpki-client(8)</a>
842: <li>Make it possible to filter the RIB by invalid and leaked prefixes
843: in bgpctl and bgplgd
844: <li>Add OpenMetrics output to bgpctl for various BGP statistics and
845: add /metrics endpoint to bgplgd
846: <li>Fix of incorrect length checks that allowed an out-of-bounds
847: read in bgpd.
1.1 benno 848: </ul>
849: <li><a href="https://man.openbsd.org/rpki-client.8">rpki-client(8)</a> saw some changes:
850: <ul>
1.13 benno 851: <li>Add a new '-H' command line option to create a shortlist of
852: repositories to synchronize to. For example, when invoking
853: "rpki-client -H rpki.ripe.net -H chloe.sobornost.net", the utility
854: will not connect to any other hosts other than the two specified
855: through the -H option.
856: <li>Add support for validating Geofeed (RFC 9092) authenticators. To
857: see an example download https://sobornost.net/geofeed.csv and run
858: "rpki-client -f geofeed.csv"
859: <li>Add support for validating Trust Anchor Key (TAK) objects. TAK
860: objects can be used to produce new Trust Anchor Locators (TALs) signed
861: by and verified against the previous Trust Anchor. See
862: draft-ietf-sidrops-signed-tal for the full specification.
863: <li>Log lines related to RRDP/HTTPS connection problems now include the
864: IP address of the problematic endpoint (in brackets).
865: <li>Improve the error message when an invalid filename is encountered
866: in the rpkiManifest field in the Subject Access Information (SIA)
867: extension.
868: <li>Emit a warning when unexpected X.509 extensions are encountered.
869: <li>Restrict the ROA ipAddrBlocks field to only allow two
870: ROAIPAddressFamily structures (one per address family). See
871: draft-ietf-sidrops-rfc6482bis.
872: <li>Check the absence of the Path Length constraint in the Basic
873: Constraints extension.
874: <li>Restrict the SIA extension to only allow the signedObject and
875: rpkiNotify accessMethods.
876: <li>Check that the Signed Object access method is present in ROA, MFT,
877: ASPA, TAK, and GBR End-Entity certificates.
878: <li>In addition to the 'rsync://' scheme, also permit other schemes
879: (such as 'https://') in the SIA signedObject access method.
880: <li>Check that the KeyUsage extension is set to nothing but
881: digitalSignature on End-Entity certificates.
1.16 jsg 882: <li>Check that the KeyUsage extension is set to nothing but keyCertSign
1.13 benno 883: and CRLSign on CA certificates.
884: <li>Check that the ExtendedKeyUsage extension is absent on CA
885: certificates.
886: <li>Fix a bug in the handling of the port of http_proxy.
887: <li>The '-r' command line option has been deprecated.
888: <li>Filemode (-f) output is now presented as a text based table.
889: <li>The 'expires' key in the JSON/CSV/OpenBGPD output formats is now
890: calculated with more accuracy. The calculation takes into account the
891: nextUpdate value of all intermediate CRLs in the signature path
892: towards the trust anchor, in addition to the expiry moment of the
893: leaf-CRL and CAs.
894: <li>Handling of CRLs and Manifests in the face of inconsistent RRDP delta
895: publications has been improved. A copy of an alternative version of
896: the applicable CRL is kept in the staging area of the cache directory,
897: in order to increase the potential for establishing a complete
898: publication point, in cases where a single publication point update
899: was smeared across multiple RRDP delta files.
900: <li>The OpenBGPD configuration output now includes validated Autonomous
901: System Provider Authorization (ASPA) payloads as an 'aspa-set {}'
902: configuration block.
903: <li>When rpki-client is invoked with increased verbosity ('-v'), the
904: current RRDP Serial & Session ID are shown to aid debugging.
905: <li>Self-signed X.509 certificates (such as Trust Anchor certificates)
906: now are considered invalid if they contain an X.509
907: AuthorityInfoAccess extension.
908: <li>Signed Objects where the CMS signing-time attribute contains a
909: timestamp later then the X.509 certificate's notAfter timestamp are
910: considered invalid.
911: <li>Manifests where the CMS signing-time attribute contains a timestamp
912: later then the Manifest eContent nextUpdate timestamp are considered
913: invalid.
914: <li>Any objects whose CRL Distribution Points extension contains a
915: CRLIssuer, CRL Reasons, or nameRelativeToCRLIssuer field are
916: considered invalid in accordance with RFC 6487 section 4.8.6.
917: <li>For every X.509 certificate the SHA-1 of the Subject Public Key is
918: calculated and compared to the Subject Key Identifier (SKI), if a
919: mismatch is found the certificate is not trusted.
920: <li>Require the outside-TBS signature OID for every X.509 intermediate
921: CA certificate and CRL to be sha256WithRSAEncryption.
922: <li>Require the RSA key pair modulus and public exponent parameters to
923: strictly conform to the RFC 7935 profile.
924: <li>Ensure there is no trailing garbage present in Signed Objects beyond
925: the self-embedded length field.
926: <li>Require RRDP Session IDs to strictly be version 4 UUIDs.
927: <li>When decoding and validating an individual RPKI file using filemode
928: (rpki-client -f file), display the signature path towards the trust
929: anchor, and the timestamp when the signature path will expire.
930: <li>When decoding and validating an individual RPKI file using filemode
931: (rpki-client -f file), display the optional CMS signing-time, and
932: non-optional X.509 notBefore, and X.509 notAfter timestamps.
1.1 benno 933: </ul>
934:
1.22 benno 935: <li>Switched <a href="https://man.openbsd.org/tftpd.8">tftpd(8)</a> to
936: default to read-only unless -w is specified for write access (the
937: previous default).
938: <li>Stopped printing the prompt for non-interactive usage of <a
939: href="https://man.openbsd.org/tftp.1">tftp(1)</a>.
940: <li>Changed <a href="https://man.openbsd.org/rarpd.8">rarpd(8)</a> to
941: only unveil /tftpboot if -t is specified.
942: <li>Added client certificate authentication and an optional SASL
943: EXTERNAL bind to <a
944: href="https://man.openbsd.org/ypldap.8">ypldap(8)</a>.
945: <li>Adjusted ipv6 address width to align the display columns better
946: in the output of <a href="https://man.openbsd.org/ndp.8">ndp(8)</a>,
947: <a href="https://man.openbsd.org/route.8">route(8)</a> and <a
948: href="https://man.openbsd.org/netstat.1">netstat(1)</a> as already
949: available in <a
950: href="https://man.openbsd.org/systat.1">systat(1)</a>'s netstat.
951: <li>Used <a href="https://man.openbsd.org/stravis.3">stravis(3)</a> to
952: sanitize redirect URIs from <a
953: href="https://man.openbsd.org/ftp.1">ftp(1)</a> fetch before printing.
1.35 ! benno 954:
1.22 benno 955: <li>Prevent an <a
1.27 jsg 956: href="https://man.openbsd.org/unwind.8">unwind(8)</a> crash when a TCP
1.22 benno 957: query is larger than the length field indicated.
958: <li>Preserve the original order of nameservers as configured via <a
959: href="https://man.openbsd.org/resolv.conf.5">resolv.conf(5)</a> in <a
960: href="https://man.openbsd.org/resolvd.8">resolvd(8)</a>.
961: <li>Restrict the characters allowed in the hostname argument of <a
962: href="https://man.openbsd.org/getaddrinfo.3">getaddrinfo(3)</a> to the
963: set [A-z0-9-_.]. Additionally two consecutive dots ('.') are not
964: allowed nor can the string start with - or '.'. This removes
965: characters like '$', '`', '\n' or '*' that can traverse the DNS
966: without problems, but have special meaning, for example a shell.
1.35 ! benno 967: <li>Fixed a number of out of bounds reads in DNS response parsing of
! 968: the async DNS resolver in libc.
1.22 benno 969: <li>Added <a
970: href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a> -M (mac) to
971: find the mac address on an interface and print it.
1.21 benno 972: <li>Added support for configuring interfaces by lladdr to support
1.27 jsg 973: interface configurations bound to a specific hardware device. The "if"
1.21 benno 974: part of the <a
975: href="https://man.openbsd.org/hostname.if.5">hostname.if(5)</a>
976: configuration file can now be a MAC address.
1.22 benno 977: <li>Limited display of wireguard peers by <a
978: href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a> to when
979: either a wireguard interface is specified or the flag "-A" is used.
980:
981: <li>Implemented the RFC 8781 PREF64 router advertisement option in
982: <a href="https://man.openbsd.org/rad.8">rad(8)</a> which is used to o
983: communicate NAT64 prefixes to hosts.
984:
985: <li>Moved the documentation of flag mappings displayed by "route show" from the <a
986: href="https://man.openbsd.org/netstat.1">netstat(1)</a> manpage to <a
987: href="https://man.openbsd.org/route.8">route(8)</a>.
988:
989: <li>Improvements in <a href="https://man.openbsd.org/nc.1">nc(1)</a>:
990: <ul>
1.27 jsg 991: <li>Stop claiming connection success in UDP mode unless true.
1.22 benno 992: <li>Do not test the connection in non-interactive mode. The test
993: writes characters to the socket which can corrupt data that is
994: possible piped into nc.
995: </ul>
996:
997: <li>Added support for newlines inside the alternative names block in
998: <a
999: href="https://man.openbsd.org/acme-client.conf.5">acme-client.conf</a>.
1000: <li>Made <a
1001: href="https://man.openbsd.org/acme-client.1">acme-client(1)</a> use
1002: time checks which eliminate time-zone variation.
1003: <li>Encode Subject Alternative Name (SAN) entries before printing in <a
1004: href="https://man.openbsd.org/acme-client.1">acme-client(1)</a>.
1005: <li>Prevent <a
1006: href="https://man.openbsd.org/acme-client.1">acme-client(1)</a> from
1007: leaking an http get request when receiving a redirect without a
1008: location header.
1.21 benno 1009:
1.13 benno 1010: <!-- smtpd -->
1011: <li>Prevented <a href="https://man.openbsd.org/smtpd.8">smtpd(8)</a>
1012: abort due to a connection from a local, scoped ipv6 address.
1013: <li>Fixed a potential NULL dereference in the unpriv child expanding
1014: %{mda} in <a href="https://man.openbsd.org/smtpd.8">smtpd(8)</a>.
1015:
1016: <li>Corrected the order of arguments for calls to <a
1017: href="https://man.openbsd.org/shutdown.2">shutdown(2)</a> on the route
1018: socket of <a href="https://man.openbsd.org/slaacd.8">slaacd(8)</a>, <a
1019: href="https://man.openbsd.org/dhcpleased.8">dhcpleased(8)</a> and <a
1020: href="https://man.openbsd.org/unwind.8">unwind(8)</a>.
1021: <li>Made <a href="https://man.openbsd.org/route.8">route(8)</a>
1022: sourceaddr print the used addresses for inet and inet6, or "default"
1023: if no sourceaddr is set and the default algorithm is used.
1024: <li>Added -mpls option to the route(8) monitor command. It can be
1025: used to restrict displayed route messages to the mpls address family.
1026: <li>Fixed <a href="https://man.openbsd.org/openrsync.1">rsync(1)</a>
1027: handling of port numbers in rsync://host[:port]/module URLS.
1028: <li>Made <a href="https://man.openbsd.org/tcpdrop.8">tcpdrop(8)</a>
1029: accept netstat-style address.port syntax.
1030: <li>Ensured <a href="https://man.openbsd.org/pfctl.8">pfctl(8)</a>
1031: correctly adds addresses to the undefined/inactive table.
1.19 kn 1032: <li>Switched <a href="https://man.openbsd.org/tftpd.8">tftpd(8)</a> to default
1033: to read-only unless <code>-w</code> is specified for write access
1034: (the previous default).
1035: <li>Changed <a href="https://man.openbsd.org/rarpd.8">rarpd(8)</a> to only unveil /tftpboot if -t is specified.
1.22 benno 1036: <li>Fixed the DIOCIGETIFACES ioctl so all network interfaces and
1037: interface groups are reported in <a
1038: href="https://man.openbsd.org/pfctl.8">pfctl(8)</a>.
1039:

1.1 benno 1041: </ul>
1042:
1043: <li><a href="https://man.openbsd.org/tmux.1">tmux(1)</a> improvements and bug fixes:
1044: <ul>
1.22 benno 1045: <li>Added scroll-top and scroll-bottom <a href="https://man.openbsd.org/tmux.1">tmux(1)</a> commands to scroll so cursor is at the top or bottom respectively.
1046: <li>Added a -T flag to <a href="https://man.openbsd.org/tmux.1">tmux(1)</a> capture-pane to capture up to the last used cell and not the full width of the pane.
1047: <li>Preserved the marked pane when renumbering windows in <a href="https://man.openbsd.org/tmux.1">tmux(1)</a>.
1048: <li>Added modified tab key sequences to <a href="https://man.openbsd.org/tmux.1">tmux(1)</a>.
1049: <li>Changed <a href="https://man.openbsd.org/tmux.1">tmux(1)</a> to only set the extended flag when searching, which allows send-keys to work.

1.1 benno 1154: </ul>
1155: </ul>
1156:
1.14 benno 1157: <li>OpenSSH 9.3 and OpenSSH 9.2<br>
1158: This release of OpenBSD includes the changes made to OpenSSH since release 9.1:
1.1 benno 1159: <ul>
1160: <li>Security
1161: <ul>
1.14 benno 1162: <li>ssh-add(1): when adding smartcard keys to ssh-agent(1) with the
1163: per-hop destination constraints (ssh-add -h ...) added in OpenSSH
1164: 8.9, a logic error prevented the constraints from being
1165: communicated to the agent. This resulted in the keys being added
1166: without constraints. The common cases of non-smartcard keys and
1167: keys without destination constraints are unaffected. This problem
1168: was reported by Luci Stanescu.
1169: <li>ssh(1): Portable OpenSSH provides an implementation of the
1170: getrrsetbyname(3) function if the standard library does not
1171: provide it, for use by the VerifyHostKeyDNS feature. A
1172: specifically crafted DNS response could cause this function to
1173: perform an out-of-bounds read of adjacent stack data, but this
1174: condition does not appear to be exploitable beyond denial-of-
1175: service to the ssh(1) client.<br>
1176: The getrrsetbyname(3) replacement is only included if the system's
1177: standard library lacks this function and portable OpenSSH was not
1178: compiled with the ldns library (--with-ldns). getrrsetbyname(3) is
1179: only invoked if using VerifyHostKeyDNS to fetch SSHFP records. This
1180: problem was found by the Coverity static analyzer.
1181: <li>sshd(8): fix a pre-authentication double-free memory fault
1182: introduced in OpenSSH 9.1. This is not believed to be exploitable,
1183: and it occurs in the unprivileged pre-auth process that is
1184: subject to chroot(2) and is further sandboxed on most major
1185: platforms.
1186: <li>ssh(8): in OpenSSH releases after 8.7, the PermitRemoteOpen option
1187: would ignore its first argument unless it was one of the special
1188: keywords "any" or "none", causing the permission list to fail open
1189: if only one permission was specified. bz3515
1190: <li>ssh(1): if the CanonicalizeHostname and CanonicalizePermittedCNAMEs
1191: options were enabled, and the system/libc resolver did not check
1192: that names in DNS responses were valid, then use of these options
1193: could allow an attacker with control of DNS to include invalid
1194: characters (possibly including wildcards) in names added to
1195: known_hosts files when they were updated. These names would still
1196: have to match the CanonicalizePermittedCNAMEs allow-list, so
1197: practical exploitation appears unlikely.
1198: </ul>
1.1 benno 1199: <li>Potentially-incompatible changes
1.14 benno 1200: <ul>
1201: <li>ssh(1): add a new EnableEscapeCommandline ssh_config(5) option that
1202: controls whether the client-side ~C escape sequence that provides a
1203: command-line is available. Among other things, the ~C command-line
1204: could be used to add additional port-forwards at runtime.<br>
1205: This option defaults to "no", disabling the ~C command-line that
1206: was previously enabled by default. Turning off the command-line
1207: allows platforms that support sandboxing of the ssh(1) client
1208: (currently only OpenBSD) to use a stricter default sandbox policy.
1209: </ul>
1210: <li>New features
1211: <ul>
1212: <li>ssh-keygen(1), ssh-keyscan(1): accept -Ohashalg=sha1|sha256 when
1213: outputting SSHFP fingerprints to allow algorithm selection. bz3493
1214: <li>sshd(8): add a `sshd -G` option that parses and prints the
1215: effective configuration without attempting to load private keys
1216: and perform other checks. This allows usage of the option before
1217: keys have been generated and for configuration evaluation and
1218: verification by unprivileged users.
1219: <li>sshd(8): add support for channel inactivity timeouts via a new
1220: sshd_config(5) ChannelTimeout directive. This allows channels that
1221: have not seen traffic in a configurable interval to be
1222: automatically closed. Different timeouts may be applied to session,
1223: X11, agent and TCP forwarding channels.
1224: <li>sshd(8): add a sshd_config UnusedConnectionTimeout option to
1225: terminate client connections that have no open channels for a
1226: length of time. This complements the ChannelTimeout option above.
1227: <li>sshd(8): add a -V (version) option to sshd like the ssh client has.
1228: <li>ssh(1): add a "Host" line to the output of ssh -G showing the
1229: original hostname argument. bz3343
1230: <li>scp(1), sftp(1): add a -X option to both scp(1) and sftp(1) to
1231: allow control over some SFTP protocol parameters: the copy buffer
1232: length and the number of in-flight requests, both of which are used
1233: during upload/download. Previously these could be controlled in
1234: sftp(1) only. This makes them available in both SFTP protocol
1235: clients using the same option character sequence.
1236: <li>ssh-keyscan(1): allow scanning of complete CIDR address ranges,
1237: e.g. "ssh-keyscan 192.168.0.0/24". If a CIDR range is passed, then
1238: it will be expanded to all possible addresses in the range
1239: including the all-0s and all-1s addresses. bz#976
1240: <li>ssh(1): support dynamic remote port forwarding in escape
1241: command-line's -R processing. bz#3499
1242: </ul>
1.1 benno 1243: <li>Bugfixes
1.14 benno 1244: <ul>
1245: <li>scp(1), sftp(1): fix progressmeter corruption on wide displays;
1246: bz3534
1247: <li>ssh-add(1), ssh-keygen(1): use RSA/SHA256 when testing usability
1248: of private keys as some systems are starting to disable RSA/SHA1
1249: in libcrypto.
1250: <li>sftp-server(8): fix a memory leak. GHPR363
1.16 jsg 1251: <li>ssh(1), sshd(8), ssh-keyscan(1): remove vestigial protocol
1.14 benno 1252: compatibility code and simplify what's left.
1253: <li>Fix a number of low-impact Coverity static analysis findings.
1254: These include several reported via bz2687
1255: <li>ssh_config(5), sshd_config(5): mention that some options are not
1256: first-match-wins.
1257: <li>Rework logging for the regression tests. Regression tests will now
1258: capture separate logs for each ssh and sshd invocation in a test.
1259: <li>ssh(1): make `ssh -Q CASignatureAlgorithms` work as the manpage
1260: says it should; bz3532.
1261: <li>ssh(1): ensure that there is a terminating newline when adding a
1262: new entry to known_hosts; bz3529
1263: <li>ssh(1): when restoring non-blocking mode to stdio fds, restore
1264: exactly the flags that ssh started with and don't just clobber them
1265: with zero, as this could also remove the append flag from the set.
1266: bz3523
1267: <li>ssh(1): avoid printf("%s", NULL) if using UserKnownHostsFile=none
1268: and a hostkey in one of the system known hosts file changes.
1269: <li>scp(1): switch scp from using pipes to a socket-pair for
1270: communication with its ssh sub-processes, matching how sftp(1)
1271: operates.
1272: <li>sshd(8): clear signal mask early in main(); sshd may have been
1273: started with one or more signals masked (sigprocmask(2) is not
1274: cleared on fork/exec) and this could interfere with various things,
1275: e.g. the login grace timer. Execution environments that fail to
1276: clear the signal mask before running sshd are clearly broken, but
1277: apparently they do exist.
1278: <li>ssh(1): warn if no host keys for hostbased auth can be loaded.
1279: <li>sshd(8): Add server debugging for hostbased auth that is queued and
1280: sent to the client after successful authentication, but also logged
1281: to assist in diagnosis of HostbasedAuthentication problems. bz3507
1282: <li>ssh(1): document use of the IdentityFile option as being usable to
1283: list public keys as well as private keys. GHPR352
1284: <li>sshd(8): check for and disallow MaxStartups values less than or
1285: equal to zero during config parsing, rather than failing later at
1286: runtime. bz3489
1287: <li>ssh-keygen(1): fix parsing of hex cert expiry times specified on
1288: the command-line when acting as a CA.
1289: <li>scp(1): when scp(1) is using the SFTP protocol for transport (the
1290: default), better match scp/rcp's handling of globs that don't match
1291: the globbed characters but do match literally (e.g. trying to
1292: transfer a file named "foo.[1]"). Previously scp(1) in SFTP mode
1293: would not match these pathnames but legacy scp/rcp mode would.
1294: bz3488
1295: <li>ssh-agent(1): document the "-O no-restrict-websafe" command-line
1296: option.
1297: <li>ssh(1): honour user's umask(2) if it is more restrictive then the
1298: ssh default (022).

1595: <section id=sourcecode>
1596: <h3>Notes about the source code</h3>
1597: <p>
1598: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1599: This file contains everything you need except for the kernel sources,
1600: which are in a separate archive.
1601: To extract:
1602: <blockquote><pre>
1603: # <kbd>mkdir -p /usr/src</kbd>
1604: # <kbd>cd /usr/src</kbd>
1605: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1606: </pre></blockquote>
1607: <p>
1608: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1609: This file contains all the kernel sources you need to rebuild kernels.
1610: To extract:
1611: <blockquote><pre>
1612: # <kbd>mkdir -p /usr/src/sys</kbd>
1613: # <kbd>cd /usr/src</kbd>
1614: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1615: </pre></blockquote>
1616: <p>
1617: Both of these trees are a regular CVS checkout. Using these trees it
1618: is possible to get a head-start on using the anoncvs servers as
1619: described <a href="anoncvs.html">here</a>.
1620: Using these files
1621: results in a much faster initial CVS update than you could expect from
1622: a fresh checkout of the full OpenBSD source tree.

1628: <h3>Ports Tree</h3>
1629: <p>
1630: A ports tree archive is also provided. To extract:
1631: <blockquote><pre>
1632: # <kbd>cd /usr</kbd>
1633: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1634: </pre></blockquote>
1635: <p>
1636: Go read the <a href="faq/ports/index.html">ports</a> page
1637: if you know nothing about ports
1638: at this point. This text is not a manual of how to use ports.
1639: Rather, it is a set of notes meant to kickstart the user on the
1640: OpenBSD ports system.
1641: <p>
1642: The <i>ports/</i> directory represents a CVS checkout of our ports.
1643: As with our complete source tree, our ports tree is available via
1644: <a href="anoncvs.html">AnonCVS</a>.
1645: So, in order to keep up to date with the -stable branch, you must make
1646: the <i>ports/</i> tree available on a read-write medium and update the tree
1647: with a command like:
1648: <blockquote><pre>
1649: # <kbd>cd /usr/ports</kbd>
1650: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_3</kbd>
1651: </pre></blockquote>
1652: <p>
1653: [Of course, you must replace the server name here with a nearby anoncvs
1654: server.]
1655: <p>
1656: Note that most ports are available as packages on our mirrors. Updated
1657: ports for the 7.3 release will be made available if problems arise.
1658: <p>
1659: If you're interested in seeing a port added, would like to help out, or just
1660: would like to know more, the mailing list
1661: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
