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

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

199: on Apple Silicon laptops and the Lenovo x13s.
1.22 benno 200:
201: <li>Added support for the backlight connector property to <a
202: href="https://man.openbsd.org/amdgpu.4">amdgpu(4)</a> as in <a
203: href="https://man.openbsd.org/inteldrm.4">inteldrm(4)</a>, making <a
204: href="https://man.openbsd.org/xbacklight.1">xbacklight(1)</a> work
205: when using the Xorg modesetting driver.
206:
1.1 benno 207: </ul>
208:
209: <li>VMM/VMD improvements
210: <ul>
1.22 benno 211: <li>Updated <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> to
212: allow guests to read MSR_HWCR and MSR_PSTATEDEF, which is necessary to
213: determine the TSC frequency on AMD families 17h and 19h.
214: <li>Allocated reference for vm and vcpu SLISTs in <a
215: href="https://man.openbsd.org/vmm.4">vmm(4)</a>, keeping vmm from
216: triggering excessive wakeup calls while iterating through the list of
217: vms while servicing an <a
218: href="https://man.openbsd.org/ioctl.2">ioctl(2)</a>.
219: <li>Set <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> RAX guest
220: register state based on VMCB.
221: <li>Removed locking in <a
222: href="https://man.openbsd.org/vmm.4">vmm(4)</a> vmm_intr_pending,
223: reducing slowdowns due to requests for a lock held while the VM is
224: running.
225: <li>Increased speed of delivery of interrupts to a running vcpu in <a
226: href="https://man.openbsd.org/vmm.4">vmm(4)</a>.
227: <li>Made <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> treat vcpu
228: lists as immutable, removing the need to reference count individual
229: vcpu objects and use a rwlock.
1.13 benno 230: <li>Implemented zero-copy operations on virtqueues in <a
231: href="https://man.openbsd.org/vmd.8">vmd(8)</a>.
232: <li>Provided a detailed e820 memory map when booting <a
233: href="https://man.openbsd.org/vmd.8">vmd(8)</a> guests with SeaBIOS.
234: When a vm initializes memory ranges, we now track what each range
235: represents. This information can be used to supply the e820 memory map
236: to SeaBIOS via the fw_cfg interface allowing it to properly
237: communicate memory ranges to a guest operating system. With this
238: special cases in ports can be removed.
239: <li>Added thread names to vm processes in <a
240: href="https://man.openbsd.org/vmd.8">vmd(8)</a>, visible in <a
241: href="https://man.openbsd.org/ps.1">ps(1)</a>.
242: <li>Hid the WAITPKG cpu feature from <a
243: href="https://man.openbsd.org/vmm.4">vmm(4)</a> guests, preventing
244: invalid instruction exceptions. Also added WAITPKG feature
245: identification to i386 and amd64.
246: <li>Changed <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> to
247: only open /dev/vmm once, having the parent process send the fd to the
248: vmm child process.
1.35 benno 249: <li>Restricted <a href="https://man.openbsd.org/vmm.4">vmm(4)</a>
250: exposed cpuid extended feature flags.
251: <li>Adjusted <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> error
252: paths to avoid removal of configuration-defined (known) VMs on error.
1.13 benno 253: <li>Stopped being paranoid about hypervisor correct PKU handling.<br>
254: Added saving and restoring guest PKRU to <a
255: href="https://man.openbsd.org/vmm.4">vmm(4)</a>. Expose the PKU cpuid
256: bit to the guest if in use on the host.
1.35 benno 257: <li>Made <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> scan the
258: PCI bus to determine bootorder strings.
1.1 benno 259: </ul>
260:
261: <li>Various new userland features:

265: and __tmpfd.
266: <li>Added <a
267: href="https://man.openbsd.org/mimmutable.2">mimmutable(2)</a> and <a
268: href="https://man.openbsd.org/munmap.2">munmap(2)</a> reporting to <a
269: href="https://man.openbsd.org/kdump.1">kdump(1)</a>.
1.13 benno 270: <li>Added <a
271: href="https://man.openbsd.org/lastcomm.1">lastcomm(1)</a> reporting
272: for process kills due to <a
273: href="https://man.openbsd.org/execve.2">execve(2)</a> from non-pinned
274: syscall address
1.1 benno 275: </ul>
276:
277: <li>Various bugfixes and tweaks in userland:
278: <ul>
1.26 jsg 279: <li>Allow TZ to contain absolute paths starting with /usr/share/zoneinfo.
280: All absolute paths were ignored in 7.2 to avoid

286: <li>Dropped support for $rc_exec in <a
287: href="https://man.openbsd.org/rc.subr.8">rc.subr(8)</a>. The rc_exec
288: function should be used instead.
289: <li>Excluded /tmp/*.shm files from /tmp cleaning in <a
290: href="https://man.openbsd.org/daily.8">daily(8)</a>. Removing them
291: interferes with programs that use shared memory via <a
292: href="https://man.openbsd.org/shm_open.3">shm_open(3)</a>.
293: <li>Added zap-to-char and zap-up-to-char to <a
294: href="https://man.openbsd.org/mg.1">mg(1)</a>. Bound zap-to-char to
295: M-z.
1.37 benno 296: <li>Fixed handling of escaped backslashes in <a

302: bytes read/written and the ? prompt to stdout, not stderr.
303: <li>Modified the vmstat view in <a
304: href="https://man.openbsd.org/systat.1">systat(1)</a> to measure
305: elapsed time using <a
306: href="https://man.openbsd.org/clock_gettime.2">clock_gettime(2)</a>.
1.37 benno 307: <li>Implemented periodic display in <a
308: href="https://man.openbsd.org/iostat.8">iostat(8)</a>.

310: display of online CPUs which can change based on the <a
311: href="https://man.openbsd.org/sysctl.2">sysctl(2)</a> sysctl setting.
1.13 benno 312: <li>Added support for a personal <a
313: href="https://man.openbsd.org/units.1">units(1)</a> library by passing
314: -f multiple times.
1.37 benno 315: <li>Changed <a href="https://man.openbsd.org/df.1">df(1)</a> to
316: round up fractional percentages.
317: <li>Fixed unbounded variable expansion in <a
318: href="https://man.openbsd.org/pkg-config.1">pkg-config(1)</a>.
319: <li>Switched to use <a
320: href="https://man.openbsd.org/llvm-strip.1">llvm-strip(1)</a> on
321: architectures that use <a
322: <!-- rc scripts -->
1.13 benno 323: <li>Made <a href="https://man.openbsd.org/rc.8">rc(8)</a> reorder
324: libraries in parallel to <a
325: href="https://man.openbsd.org/netstart.8">netstart(8)</a>, as this
326: does not depend on network access.
1.22 benno 327: <li>Made <a href="https://man.openbsd.org/rc.8">rc(8)</a> print the
328: name of each library before relinking as a signal to the operator that
329: boot has not stalled.
1.35 benno 330: <!-- audio -->
1.13 benno 331: <li>Added the <a
332: href="https://man.openbsd.org/audioctl.8">audioctl(8)</a> -w option to
333: display variables periodically.
334: <li>Added short options for <a
335: href="https://man.openbsd.org/timeout.1">timeout(1)</a> --foreground
336: and --preserve-status.<br>
337: Added signal as a full argument name for <a
338: href="https://man.openbsd.org/timeout.1">timeout(1)</a> -s.
339: <li>Fixed .wav files generated by <a
1.35 benno 340: href="https://man.openbsd.org/aucat.1">aucat(1)</a> by using extended
1.13 benno 341: header format.
1.35 benno 342: <!-- disks ... -->
1.13 benno 343: <li>In <a
344: href="https://man.openbsd.org/disklabel.8">disklabel(8)</a>, use the
345: size of the largest chunk of free space, not the total of all such
346: chunks, when checking for sufficient space to add a partition.
1.35 benno 347: <li>Extended <a
348: href="https://man.openbsd.org/disklabel.8">disklabel(8)</a> template
349: parsing to allow "[mount point] *" as the specification for putting
350: the maximum available free space into a partition, and extended
351: command line parsing to allow "T-" as the specification to read the
352: template from stdin.
1.13 benno 353: href="https://man.openbsd.org/ld.lld.1">ld.lld(1)</a>.
1.1 benno 354: </ul>
355:
356: <li>Improved hardware support and driver bugfixes, including:
357: <ul>
1.36 benno 358: <li>Extended arm64 suspend/resume to include support for parking
359: CPUs in a WFE/WFI loop.
360: <li>Put CPUs in the lowest P-state before the final suspend step,
361: needed for systems where we park CPUs in a low-power idle state
362: ourselves.
1.13 benno 363:

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

1.1 benno 1141: </ul>
1142: </ul>
1143:
1.14 benno 1144: <li>OpenSSH 9.3 and OpenSSH 9.2<br>
1145: This release of OpenBSD includes the changes made to OpenSSH since release 9.1:
1.1 benno 1146: <ul>
1147: <li>Security
1148: <ul>
1.14 benno 1149: <li>ssh-add(1): when adding smartcard keys to ssh-agent(1) with the
1150: per-hop destination constraints (ssh-add -h ...) added in OpenSSH
1151: 8.9, a logic error prevented the constraints from being
1152: communicated to the agent. This resulted in the keys being added
1153: without constraints. The common cases of non-smartcard keys and
1154: keys without destination constraints are unaffected. This problem
1155: was reported by Luci Stanescu.
1156: <li>ssh(1): Portable OpenSSH provides an implementation of the
1157: getrrsetbyname(3) function if the standard library does not
1158: provide it, for use by the VerifyHostKeyDNS feature. A
1159: specifically crafted DNS response could cause this function to
1160: perform an out-of-bounds read of adjacent stack data, but this
1161: condition does not appear to be exploitable beyond denial-of-
1162: service to the ssh(1) client.<br>
1163: The getrrsetbyname(3) replacement is only included if the system's
1164: standard library lacks this function and portable OpenSSH was not
1165: compiled with the ldns library (--with-ldns). getrrsetbyname(3) is
1166: only invoked if using VerifyHostKeyDNS to fetch SSHFP records. This
1167: problem was found by the Coverity static analyzer.
1168: <li>sshd(8): fix a pre-authentication double-free memory fault
1169: introduced in OpenSSH 9.1. This is not believed to be exploitable,
1170: and it occurs in the unprivileged pre-auth process that is
1171: subject to chroot(2) and is further sandboxed on most major
1172: platforms.
1173: <li>ssh(8): in OpenSSH releases after 8.7, the PermitRemoteOpen option
1174: would ignore its first argument unless it was one of the special
1175: keywords "any" or "none", causing the permission list to fail open
1176: if only one permission was specified. bz3515
1177: <li>ssh(1): if the CanonicalizeHostname and CanonicalizePermittedCNAMEs
1178: options were enabled, and the system/libc resolver did not check
1179: that names in DNS responses were valid, then use of these options
1180: could allow an attacker with control of DNS to include invalid
1181: characters (possibly including wildcards) in names added to
1182: known_hosts files when they were updated. These names would still
1183: have to match the CanonicalizePermittedCNAMEs allow-list, so
1184: practical exploitation appears unlikely.
1185: </ul>
1.1 benno 1186: <li>Potentially-incompatible changes
1.14 benno 1187: <ul>
1188: <li>ssh(1): add a new EnableEscapeCommandline ssh_config(5) option that
1189: controls whether the client-side ~C escape sequence that provides a
1190: command-line is available. Among other things, the ~C command-line
1191: could be used to add additional port-forwards at runtime.<br>
1192: This option defaults to "no", disabling the ~C command-line that
1193: was previously enabled by default. Turning off the command-line
1194: allows platforms that support sandboxing of the ssh(1) client
1195: (currently only OpenBSD) to use a stricter default sandbox policy.
1196: </ul>
1197: <li>New features
1198: <ul>
1199: <li>ssh-keygen(1), ssh-keyscan(1): accept -Ohashalg=sha1|sha256 when
1200: outputting SSHFP fingerprints to allow algorithm selection. bz3493
1201: <li>sshd(8): add a `sshd -G` option that parses and prints the
1202: effective configuration without attempting to load private keys
1203: and perform other checks. This allows usage of the option before
1204: keys have been generated and for configuration evaluation and
1205: verification by unprivileged users.
1206: <li>sshd(8): add support for channel inactivity timeouts via a new
1207: sshd_config(5) ChannelTimeout directive. This allows channels that
1208: have not seen traffic in a configurable interval to be
1209: automatically closed. Different timeouts may be applied to session,
1210: X11, agent and TCP forwarding channels.
1211: <li>sshd(8): add a sshd_config UnusedConnectionTimeout option to
1212: terminate client connections that have no open channels for a
1213: length of time. This complements the ChannelTimeout option above.
1214: <li>sshd(8): add a -V (version) option to sshd like the ssh client has.
1215: <li>ssh(1): add a "Host" line to the output of ssh -G showing the
1216: original hostname argument. bz3343
1217: <li>scp(1), sftp(1): add a -X option to both scp(1) and sftp(1) to
1218: allow control over some SFTP protocol parameters: the copy buffer
1219: length and the number of in-flight requests, both of which are used
1220: during upload/download. Previously these could be controlled in
1221: sftp(1) only. This makes them available in both SFTP protocol
1222: clients using the same option character sequence.
1223: <li>ssh-keyscan(1): allow scanning of complete CIDR address ranges,
1224: e.g. "ssh-keyscan 192.168.0.0/24". If a CIDR range is passed, then
1225: it will be expanded to all possible addresses in the range
1226: including the all-0s and all-1s addresses. bz#976
1227: <li>ssh(1): support dynamic remote port forwarding in escape
1228: command-line's -R processing. bz#3499
1229: </ul>
1.1 benno 1230: <li>Bugfixes
1.14 benno 1231: <ul>
1232: <li>scp(1), sftp(1): fix progressmeter corruption on wide displays;
1233: bz3534
1234: <li>ssh-add(1), ssh-keygen(1): use RSA/SHA256 when testing usability
1235: of private keys as some systems are starting to disable RSA/SHA1
1236: in libcrypto.
1237: <li>sftp-server(8): fix a memory leak. GHPR363
1.16 jsg 1238: <li>ssh(1), sshd(8), ssh-keyscan(1): remove vestigial protocol
1.14 benno 1239: compatibility code and simplify what's left.
1240: <li>Fix a number of low-impact Coverity static analysis findings.
1241: These include several reported via bz2687
1242: <li>ssh_config(5), sshd_config(5): mention that some options are not
1243: first-match-wins.
1244: <li>Rework logging for the regression tests. Regression tests will now
1245: capture separate logs for each ssh and sshd invocation in a test.
1246: <li>ssh(1): make `ssh -Q CASignatureAlgorithms` work as the manpage
1247: says it should; bz3532.
1248: <li>ssh(1): ensure that there is a terminating newline when adding a
1249: new entry to known_hosts; bz3529
1250: <li>ssh(1): when restoring non-blocking mode to stdio fds, restore
1251: exactly the flags that ssh started with and don't just clobber them
1252: with zero, as this could also remove the append flag from the set.
1253: bz3523
1254: <li>ssh(1): avoid printf("%s", NULL) if using UserKnownHostsFile=none
1255: and a hostkey in one of the system known hosts file changes.
1256: <li>scp(1): switch scp from using pipes to a socket-pair for
1257: communication with its ssh sub-processes, matching how sftp(1)
1258: operates.
1259: <li>sshd(8): clear signal mask early in main(); sshd may have been
1260: started with one or more signals masked (sigprocmask(2) is not
1261: cleared on fork/exec) and this could interfere with various things,
1262: e.g. the login grace timer. Execution environments that fail to
1263: clear the signal mask before running sshd are clearly broken, but
1264: apparently they do exist.
1265: <li>ssh(1): warn if no host keys for hostbased auth can be loaded.
1266: <li>sshd(8): Add server debugging for hostbased auth that is queued and
1267: sent to the client after successful authentication, but also logged
1268: to assist in diagnosis of HostbasedAuthentication problems. bz3507
1269: <li>ssh(1): document use of the IdentityFile option as being usable to
1270: list public keys as well as private keys. GHPR352
1271: <li>sshd(8): check for and disallow MaxStartups values less than or
1272: equal to zero during config parsing, rather than failing later at
1273: runtime. bz3489
1274: <li>ssh-keygen(1): fix parsing of hex cert expiry times specified on
1275: the command-line when acting as a CA.
1276: <li>scp(1): when scp(1) is using the SFTP protocol for transport (the
1277: default), better match scp/rcp's handling of globs that don't match
1278: the globbed characters but do match literally (e.g. trying to
1279: transfer a file named "foo.[1]"). Previously scp(1) in SFTP mode
1280: would not match these pathnames but legacy scp/rcp mode would.
1281: bz3488
1282: <li>ssh-agent(1): document the "-O no-restrict-websafe" command-line
1283: option.
1284: <li>ssh(1): honour user's umask(2) if it is more restrictive then the
1285: ssh default (022).

1577: <section id=sourcecode>
1578: <h3>Notes about the source code</h3>
1579: <p>
1580: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1581: This file contains everything you need except for the kernel sources,
1582: which are in a separate archive.
1583: To extract:
1584: <blockquote><pre>
1585: # <kbd>mkdir -p /usr/src</kbd>
1586: # <kbd>cd /usr/src</kbd>
1587: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1588: </pre></blockquote>
1589: <p>
1590: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1591: This file contains all the kernel sources you need to rebuild kernels.
1592: To extract:
1593: <blockquote><pre>
1594: # <kbd>mkdir -p /usr/src/sys</kbd>
1595: # <kbd>cd /usr/src</kbd>
1596: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1597: </pre></blockquote>
1598: <p>
1599: Both of these trees are a regular CVS checkout. Using these trees it
1600: is possible to get a head-start on using the anoncvs servers as
1601: described <a href="anoncvs.html">here</a>.
1602: Using these files
1603: results in a much faster initial CVS update than you could expect from
1604: a fresh checkout of the full OpenBSD source tree.

1610: <h3>Ports Tree</h3>
1611: <p>
1612: A ports tree archive is also provided. To extract:
1613: <blockquote><pre>
1614: # <kbd>cd /usr</kbd>
1615: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1616: </pre></blockquote>
1617: <p>
1618: Go read the <a href="faq/ports/index.html">ports</a> page
1619: if you know nothing about ports
1620: at this point. This text is not a manual of how to use ports.
1621: Rather, it is a set of notes meant to kickstart the user on the
1622: OpenBSD ports system.
1623: <p>
1624: The <i>ports/</i> directory represents a CVS checkout of our ports.
1625: As with our complete source tree, our ports tree is available via
1626: <a href="anoncvs.html">AnonCVS</a>.
1627: So, in order to keep up to date with the -stable branch, you must make
1628: the <i>ports/</i> tree available on a read-write medium and update the tree
1629: with a command like:
1630: <blockquote><pre>
1631: # <kbd>cd /usr/ports</kbd>
1632: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_3</kbd>
1633: </pre></blockquote>
1634: <p>
1635: [Of course, you must replace the server name here with a nearby anoncvs
1636: server.]
1637: <p>
1638: Note that most ports are available as packages on our mirrors. Updated
1639: ports for the 7.3 release will be made available if problems arise.
1640: <p>
1641: If you're interested in seeing a port added, would like to help out, or just
1642: would like to know more, the mailing list
1643: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
