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

200: on Apple Silicon laptops and the Lenovo x13s.
1.22 benno 201:
202: <li>Added support for the backlight connector property to <a
203: href="https://man.openbsd.org/amdgpu.4">amdgpu(4)</a> as in <a
204: href="https://man.openbsd.org/inteldrm.4">inteldrm(4)</a>, making <a
205: href="https://man.openbsd.org/xbacklight.1">xbacklight(1)</a> work
206: when using the Xorg modesetting driver.
207:
1.1 benno 208: </ul>
209:
210: <li>VMM/VMD improvements
211: <ul>
1.13 benno 212:
1.22 benno 213: <li>Updated <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> to
214: allow guests to read MSR_HWCR and MSR_PSTATEDEF, which is necessary to
215: determine the TSC frequency on AMD families 17h and 19h.
216: <li>Allocated reference for vm and vcpu SLISTs in <a
217: href="https://man.openbsd.org/vmm.4">vmm(4)</a>, keeping vmm from
218: triggering excessive wakeup calls while iterating through the list of
219: vms while servicing an <a
220: href="https://man.openbsd.org/ioctl.2">ioctl(2)</a>.
221: <li>Set <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> RAX guest
222: register state based on VMCB.
223: <li>Removed locking in <a
224: href="https://man.openbsd.org/vmm.4">vmm(4)</a> vmm_intr_pending,
225: reducing slowdowns due to requests for a lock held while the VM is
226: running.
227: <li>Increased speed of delivery of interrupts to a running vcpu in <a
228: href="https://man.openbsd.org/vmm.4">vmm(4)</a>.
229: <li>Made <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> treat vcpu
230: lists as immutable, removing the need to reference count individual
231: vcpu objects and use a rwlock.
1.13 benno 232: <li>Implemented zero-copy operations on virtqueues in <a
233: href="https://man.openbsd.org/vmd.8">vmd(8)</a>.
234: <li>Provided a detailed e820 memory map when booting <a
235: href="https://man.openbsd.org/vmd.8">vmd(8)</a> guests with SeaBIOS.
236: When a vm initializes memory ranges, we now track what each range
237: represents. This information can be used to supply the e820 memory map
238: to SeaBIOS via the fw_cfg interface allowing it to properly
239: communicate memory ranges to a guest operating system. With this
240: special cases in ports can be removed.
241:
242: <li>Added thread names to vm processes in <a
243: href="https://man.openbsd.org/vmd.8">vmd(8)</a>, visible in <a
244: href="https://man.openbsd.org/ps.1">ps(1)</a>.
245: <li>Hid the WAITPKG cpu feature from <a
246: href="https://man.openbsd.org/vmm.4">vmm(4)</a> guests, preventing
247: invalid instruction exceptions. Also added WAITPKG feature
248: identification to i386 and amd64.
249:
250: <li>Changed <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> to
251: only open /dev/vmm once, having the parent process send the fd to the
252: vmm child process.
253: <li>Restricted <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> exposed cpuid extended feature flags.
254: <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.
255: <li>Stopped being paranoid about hypervisor correct PKU handling.<br>
256: Added saving and restoring guest PKRU to <a
257: href="https://man.openbsd.org/vmm.4">vmm(4)</a>. Expose the PKU cpuid
258: bit to the guest if in use on the host.
1.27 jsg 259: <li>Made <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> scan the PCI bus to determine bootorder strings.
1.1 benno 260: </ul>
261:
262: <li>Various new userland features:
263: <ul>
1.13 benno 264:

268: and __tmpfd.
269: <li>Added <a
270: href="https://man.openbsd.org/mimmutable.2">mimmutable(2)</a> and <a
271: href="https://man.openbsd.org/munmap.2">munmap(2)</a> reporting to <a
272: href="https://man.openbsd.org/kdump.1">kdump(1)</a>.
1.13 benno 273: <li>Added <a
274: href="https://man.openbsd.org/lastcomm.1">lastcomm(1)</a> reporting
275: for process kills due to <a
276: href="https://man.openbsd.org/execve.2">execve(2)</a> from non-pinned
277: syscall address
1.1 benno 278: </ul>
279:
280: <li>Various bugfixes and tweaks in userland:
281: <ul>
1.13 benno 282:
1.26 jsg 283: <li>Allow TZ to contain absolute paths starting with /usr/share/zoneinfo.
284: All absolute paths were ignored in 7.2 to avoid

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

304: bytes read/written and the ? prompt to stdout, not stderr.
305: <li>Modified the vmstat view in <a
306: href="https://man.openbsd.org/systat.1">systat(1)</a> to measure
307: elapsed time using <a
308: href="https://man.openbsd.org/clock_gettime.2">clock_gettime(2)</a>.
309: <li>Fixed handling of escaped backslashes in <a
310: href="https://man.openbsd.org/vi.1">vi(1)</a> ex_range.
311: <li>Corrected <a href="https://man.openbsd.org/top.1">top(1)</a>
312: display of online CPUs which can change based on the <a
313: href="https://man.openbsd.org/sysctl.2">sysctl(2)</a> sysctl setting.
1.13 benno 314: <li>Added support for a personal <a
315: href="https://man.openbsd.org/units.1">units(1)</a> library by passing
316: -f multiple times.
317:
318: <li>Made <a href="https://man.openbsd.org/rc.8">rc(8)</a> reorder
319: libraries in parallel to <a
320: href="https://man.openbsd.org/netstart.8">netstart(8)</a>, as this
321: does not depend on network access.
322:
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:
333: <li>Added the <a
334: href="https://man.openbsd.org/audioctl.8">audioctl(8)</a> -w option to
335: display variables periodically.
336: <li>Added short options for <a
337: href="https://man.openbsd.org/timeout.1">timeout(1)</a> --foreground
338: and --preserve-status.<br>
339: Added signal as a full argument name for <a
340: href="https://man.openbsd.org/timeout.1">timeout(1)</a> -s.
341:
342: <li>Fixed .wav files generated by <a
1.22 benno 343: ; href="https://man.openbsd.org/aucat.1">aucat(1)</a> by using extended
1.13 benno 344: header format.
345: <li>In <a
346: href="https://man.openbsd.org/disklabel.8">disklabel(8)</a>, use the
347: size of the largest chunk of free space, not the total of all such
348: chunks, when checking for sufficient space to add a partition.
349: <li>Fixed unbounded variable expansion in <a
350: href="https://man.openbsd.org/pkg-config.1">pkg-config(1)</a>.
351: <li>Switched to use <a
352: href="https://man.openbsd.org/llvm-strip.1">llvm-strip(1)</a> on
353: architectures that use <a
354: href="https://man.openbsd.org/ld.lld.1">ld.lld(1)</a>.
355: <li>Extended <a
356: href="https://man.openbsd.org/disklabel.8">disklabel(8)</a> template
357: parsing to allow "[mount point] *" as the specification for putting
358: the maximum available free space into a partition, and extended
359: command line parsing to allow "T-" as the specification to read the
360: template from stdin.
361: <li>Fixed a number of out of bounds reads in DNS response parsing.
362:
1.1 benno 363: </ul>
364:
365: <li>Improved hardware support and driver bugfixes, including:
366: <ul>
1.13 benno 367:

709: href="https://man.openbsd.org/mprotect.2">mprotect(2)</a> or <a
710: href="https://man.openbsd.org/munmap.2">munmap(2)</a> fail with EPERM.
711: Most of the program static address space is now automatically
712: immutable (main program, ld.so, main stack, load-time shared
713: libraries, and dlopen()'d libraries mapped without RTLD_NODELETE).
714: Programmers can request non-immutable static data using the
715: "openbsd.mutable" section, or manually bring immutability to (page
716: aligned heap objects) using <a
717: href="https://man.openbsd.org/mimmutable.2">mimmutable(2)</a>.
718: <li>Some architectures now have non-readable code ("xonly"), both from
719: the perspective of userland reading its own memory, or the kernel
720: trying to read memory in a system call. Many sloppy practices in
721: userland code had to be repaired to allow this. The <a
722: href="https://man.openbsd.org/ld.lld.1">linker (ld.lld(1))</a> option
723: --execute-only is enabled by default. In order of development: arm64,
724: riscv64, hppa, amd64, powerpc64, powerpc (G5 only), octeon. sparc64
725: (sun4u only, unfinished).
726: <li>On all architectures which lack hardware-enforcement of xonly,
727: system calls are now prevented from reading (via <a
728: href="https://man.openbsd.org/copyin.9">copyin(9)</a>/copyinst)
729: inside the program's main text, ld.so text, sigtramp text, or libc.so
730: text.
731: <li>can still benefit from switching to --execute-only binaries if the
732: cpu generates different traps for instruction-fetch versus data-fetch.
733: The VM system will not allow memory to be read before it was executed
734: which is valuable together with library relinking. Architectures
735: switched over include loongson.
736: <li><a href="https://man.openbsd.org/ld.so.1">ld.so(1)</a> and crt0
737: register the location of the <a
738: href="https://man.openbsd.org/execve.2">execve(2)</a> stub with the
739: kernel using pinsyscall(2), after which the kernel only accepts an
740: execve call from that specific location.
1.13 benno 741: <li>Added <a href="https://man.openbsd.org/execve.2">execve(2)</a>
742: violations of <a
743: href="https://man.openbsd.org/pinsyscall.2">pinsyscall(2)</a> policy
744: to the daily mail, available by setting rc.conf.local(5)
745: accounting=YES.
1.23 benno 746: <li>Added retguard (consistency-check the return address on the
747: stack) to amd64 syscalls.
748: <li>sshd random relinking at boot: Randomly relink and install <a
749: href="https://man.openbsd.org/sshd.8">sshd(8)</a>, resulting
750: in a sshd binary with unknown address layout after every reboot.
1.13 benno 751: <li>Add another mitigation against classic BROP on systems without
752: execute-only mmu hardware-enforcement. A range-checking wrapper in
1.23 benno 753: front of <a href="https://man.openbsd.org/copyin.9">copyin(9)</a> and
754: href="https://man.openbsd.org/copyinstr.9">copyinstr(9)</a> ensures
755: the userland source address doesn't overlap the main program text and
756: other text segments, thereby making this address ranges unreadable to
757: the kernel. No programs have been discovered which require reading
758: their own text segments with a system call.
1.22 benno 759: <li>On arm64, introduce mitigation of the Spectre-BHB (Branch
760: History Injection) CPU vulnerability by using core-specific trampoline
761: vectors.
1.23 benno 762: <li>Enabled the arm64 Data Independent Timing (DIT) feature in both the kernel and
763: userland on CPUs that support it to mitigate timing side-channel
1.22 benno 764: attacks.
1.1 benno 765: </ul>
766:
767: <li>Changes in the network stack:
768: <ul>
1.13 benno 769:
1.24 jsg 770: <li>Made /dev/pf a clonable device to better track kernel resources
1.22 benno 771: used by processes.
772: <li>Modified TCP receive buffer size auto-scaling to use the smoothed
773: RTT (SRTT) instead of the timestamp option, which improves performance
774: on high latency networks if the timestamp option isn't available.
1.24 jsg 775: <li>Relaxed the requirement for multicast support of interfaces for
1.22 benno 776: configuring IPv6. This allows non-multicast interfaces such as
777: point-to-point interfaces and the NBMA / point-to-multipoint
778: interfaces like mpe(4), mgre(4) and wg(4) to work with IPv6.
779: <li>Use the new <a
780: href="https://man.openbsd.org/getnsecruntime.9">getnsecruntime(9)</a>
781: timer to check the TCP_KEEPALIVE timer only against the system
782: runtime, not the uptime. Prevents TCP connections to fail after
1.24 jsg 783: waking up from suspend.
1.13 benno 784: <li>Used stoeplitz (symmetric Toeplitz hash algorithm) to generate a
785: hash/flowid for <a href="https://man.openbsd.org/pf.4">pf(4)</a> state
786: keys. With this change, pf will hash traffic the same way that
787: hardware using a stoeplitz key will hash incoming traffic on rings.
1.27 jsg 788: stoeplitz is also used by the TCP stack to generate a flow id, which
1.13 benno 789: is used to pick which transmit ring is used on nics with multiple
790: queues too. using the same algorithm throughout the stack encourages
791: affinity of packets to rings and softnet threads the whole way
792: through.
793: <li>Prevented possible kernel crashes by dropping TCP packets with
794: destination port 0 in <a href="https://man.openbsd.org/pf.4">pf(4)</a>
795: and the stack.
796: <li>Fixed a endian swap bug causing problems with <a
1.27 jsg 797: href="https://man.openbsd.org/vlan.4">vlan(4)</a> on <a
1.13 benno 798: href="https://man.openbsd.org/em.4">em(4)</a> sparc64 systems.
799: <li>Denied "pipex no" tunnel setting for <a
800: href="https://man.openbsd.org/pppx.4">pppx(4)</a> interfaces.
1.22 benno 801: <li>Fixed <a href="https://man.openbsd.org/pfsync.4">pfsync(4)</a>
802: crashing on pf_state_key removal.
1.13 benno 803: <li>Fixed a panic in <a
804: href="https://man.openbsd.org/pfsync.4">pfsync(4)</a> when there are
805: no data ready for bulk transfer.
806: <li>Turned off TCP Segmentation Offload (TSO) if interface is added
807: to layer 2 devices.
808: <li>Improved <a href="https://man.openbsd.org/vnet.4">vnet(4)</a>
809: to work better in busy conditions.
810: <li>Added a <a href="https://man.openbsd.org/bpf.4">bpf(4)</a> timeout
811: (BIOCSWTIMEOUT) between capturing a packet and making the buffer
812: readable, preventing for example <a
813: href="https://man.openbsd.org/pflogd.8">pflogd(8)</a> waking every
814: half second even if there is nothing to read. By default this buffer
815: is infinite and must be filled to become readable.
816: <li>Avoided enabling TSO on interfaces which are already attached to a bridge.
817: </ul>
1.1 benno 818:
819: <li>Routing daemons and other userland network improvements:
820: <ul>
821: <li>IPsec support was improved:
822: <ul>
1.13 benno 823: <li>Added <a href="https://man.openbsd.org/iked.8">iked(8)</a>
824: support for configuring multiple name servers.
825: <li>Synced proc.c from <a
826: href="https://man.openbsd.org/vmd.8">vmd(8)</a> to <a
827: href="https://man.openbsd.org/iked.8">iked(8)</a> to enabled fork +
828: exec for all processes. This gives each process a fresh and unique
829: address space to further improve randomization of ASLR and stack
830: protector.
831: </ul>
832:
833: <li>In <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>, <a
834: href="https://man.openbsd.org/bgpctl.8">bgpctl(8)</a> and <a
835: href="https://man.openbsd.org/bgplgd.8">bgplgd(8)</a>:
836: <ul>
837: <li>Improved performance by optimising the output filters
1.16 jsg 838: <li>Add Autonomous System Provider Authorization (ASPA) validation
1.13 benno 839: based on draft-ietf-sidrops-aspa-verification-12
840: <li>Introduce avs (ASPA validation state) filter and bgpctl
841: filter argument
842: <li>Add ASPA support for the RTR protocol based on
843: draft-ietf-sidrops-8210bis-10
844: <li>Improve open policy (RFC 9234) support and enable the capability
845: automatically if a role is specified for the peer
846: <li>Introduce a per neighbor 'role' configuration option to specify
847: the session role used by ASPA verification and the open policy
848: capability. The 'announce policy' statement was simplified at
849: the same time.
850: <li>Improve startup behaviour by introducing a small delay before
851: opening the connection to a new peer
852: <li>Support for aspa-set table config which can be provided by
853: <a
854: href="https://man.openbsd.org/rpki-client.8">rpki-client(8)</a>
855: <li>Make it possible to filter the RIB by invalid and leaked prefixes
856: in bgpctl and bgplgd
857: <li>Add OpenMetrics output to bgpctl for various BGP statistics and
858: add /metrics endpoint to bgplgd
859: <li>Fix of incorrect length checks that allowed an out-of-bounds
860: read in bgpd.
1.1 benno 861: </ul>
862: <li><a href="https://man.openbsd.org/rpki-client.8">rpki-client(8)</a> saw some changes:
863: <ul>
1.13 benno 864: <li>Add a new '-H' command line option to create a shortlist of
865: repositories to synchronize to. For example, when invoking
866: "rpki-client -H rpki.ripe.net -H chloe.sobornost.net", the utility
867: will not connect to any other hosts other than the two specified
868: through the -H option.
869: <li>Add support for validating Geofeed (RFC 9092) authenticators. To
870: see an example download https://sobornost.net/geofeed.csv and run
871: "rpki-client -f geofeed.csv"
872: <li>Add support for validating Trust Anchor Key (TAK) objects. TAK
873: objects can be used to produce new Trust Anchor Locators (TALs) signed
874: by and verified against the previous Trust Anchor. See
875: draft-ietf-sidrops-signed-tal for the full specification.
876: <li>Log lines related to RRDP/HTTPS connection problems now include the
877: IP address of the problematic endpoint (in brackets).
878: <li>Improve the error message when an invalid filename is encountered
879: in the rpkiManifest field in the Subject Access Information (SIA)
880: extension.
881: <li>Emit a warning when unexpected X.509 extensions are encountered.
882: <li>Restrict the ROA ipAddrBlocks field to only allow two
883: ROAIPAddressFamily structures (one per address family). See
884: draft-ietf-sidrops-rfc6482bis.
885: <li>Check the absence of the Path Length constraint in the Basic
886: Constraints extension.
887: <li>Restrict the SIA extension to only allow the signedObject and
888: rpkiNotify accessMethods.
889: <li>Check that the Signed Object access method is present in ROA, MFT,
890: ASPA, TAK, and GBR End-Entity certificates.
891: <li>In addition to the 'rsync://' scheme, also permit other schemes
892: (such as 'https://') in the SIA signedObject access method.
893: <li>Check that the KeyUsage extension is set to nothing but
894: digitalSignature on End-Entity certificates.
1.16 jsg 895: <li>Check that the KeyUsage extension is set to nothing but keyCertSign
1.13 benno 896: and CRLSign on CA certificates.
897: <li>Check that the ExtendedKeyUsage extension is absent on CA
898: certificates.
899: <li>Fix a bug in the handling of the port of http_proxy.
900: <li>The '-r' command line option has been deprecated.
901: <li>Filemode (-f) output is now presented as a text based table.
902: <li>The 'expires' key in the JSON/CSV/OpenBGPD output formats is now
903: calculated with more accuracy. The calculation takes into account the
904: nextUpdate value of all intermediate CRLs in the signature path
905: towards the trust anchor, in addition to the expiry moment of the
906: leaf-CRL and CAs.
907: <li>Handling of CRLs and Manifests in the face of inconsistent RRDP delta
908: publications has been improved. A copy of an alternative version of
909: the applicable CRL is kept in the staging area of the cache directory,
910: in order to increase the potential for establishing a complete
911: publication point, in cases where a single publication point update
912: was smeared across multiple RRDP delta files.
913: <li>The OpenBGPD configuration output now includes validated Autonomous
914: System Provider Authorization (ASPA) payloads as an 'aspa-set {}'
915: configuration block.
916: <li>When rpki-client is invoked with increased verbosity ('-v'), the
917: current RRDP Serial & Session ID are shown to aid debugging.
918: <li>Self-signed X.509 certificates (such as Trust Anchor certificates)
919: now are considered invalid if they contain an X.509
920: AuthorityInfoAccess extension.
921: <li>Signed Objects where the CMS signing-time attribute contains a
922: timestamp later then the X.509 certificate's notAfter timestamp are
923: considered invalid.
924: <li>Manifests where the CMS signing-time attribute contains a timestamp
925: later then the Manifest eContent nextUpdate timestamp are considered
926: invalid.
927: <li>Any objects whose CRL Distribution Points extension contains a
928: CRLIssuer, CRL Reasons, or nameRelativeToCRLIssuer field are
929: considered invalid in accordance with RFC 6487 section 4.8.6.
930: <li>For every X.509 certificate the SHA-1 of the Subject Public Key is
931: calculated and compared to the Subject Key Identifier (SKI), if a
932: mismatch is found the certificate is not trusted.
933: <li>Require the outside-TBS signature OID for every X.509 intermediate
934: CA certificate and CRL to be sha256WithRSAEncryption.
935: <li>Require the RSA key pair modulus and public exponent parameters to
936: strictly conform to the RFC 7935 profile.
937: <li>Ensure there is no trailing garbage present in Signed Objects beyond
938: the self-embedded length field.
939: <li>Require RRDP Session IDs to strictly be version 4 UUIDs.
940: <li>When decoding and validating an individual RPKI file using filemode
941: (rpki-client -f file), display the signature path towards the trust
942: anchor, and the timestamp when the signature path will expire.
943: <li>When decoding and validating an individual RPKI file using filemode
944: (rpki-client -f file), display the optional CMS signing-time, and
945: non-optional X.509 notBefore, and X.509 notAfter timestamps.
1.1 benno 946: </ul>
947:
1.22 benno 948: <li>Switched <a href="https://man.openbsd.org/tftpd.8">tftpd(8)</a> to
949: default to read-only unless -w is specified for write access (the
950: previous default).
951: <li>Stopped printing the prompt for non-interactive usage of <a
952: href="https://man.openbsd.org/tftp.1">tftp(1)</a>.
953: <li>Changed <a href="https://man.openbsd.org/rarpd.8">rarpd(8)</a> to
954: only unveil /tftpboot if -t is specified.
955: <li>Added client certificate authentication and an optional SASL
956: EXTERNAL bind to <a
957: href="https://man.openbsd.org/ypldap.8">ypldap(8)</a>.
958: <li>Adjusted ipv6 address width to align the display columns better
959: in the output of <a href="https://man.openbsd.org/ndp.8">ndp(8)</a>,
960: <a href="https://man.openbsd.org/route.8">route(8)</a> and <a
961: href="https://man.openbsd.org/netstat.1">netstat(1)</a> as already
962: available in <a
963: href="https://man.openbsd.org/systat.1">systat(1)</a>'s netstat.
964: <li>Used <a href="https://man.openbsd.org/stravis.3">stravis(3)</a> to
965: sanitize redirect URIs from <a
966: href="https://man.openbsd.org/ftp.1">ftp(1)</a> fetch before printing.
967: <li>Prevent an <a
1.27 jsg 968: href="https://man.openbsd.org/unwind.8">unwind(8)</a> crash when a TCP
1.22 benno 969: query is larger than the length field indicated.
970:
971: <li>Preserve the original order of nameservers as configured via <a
972: href="https://man.openbsd.org/resolv.conf.5">resolv.conf(5)</a> in <a
973: href="https://man.openbsd.org/resolvd.8">resolvd(8)</a>.
974:
975: <li>Restrict the characters allowed in the hostname argument of <a
976: href="https://man.openbsd.org/getaddrinfo.3">getaddrinfo(3)</a> to the
977: set [A-z0-9-_.]. Additionally two consecutive dots ('.') are not
978: allowed nor can the string start with - or '.'. This removes
979: characters like '$', '`', '\n' or '*' that can traverse the DNS
980: without problems, but have special meaning, for example a shell.
981:
982: <li>Added <a
983: href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a> -M (mac) to
984: find the mac address on an interface and print it.
1.21 benno 985: <li>Added support for configuring interfaces by lladdr to support
1.27 jsg 986: interface configurations bound to a specific hardware device. The "if"
1.21 benno 987: part of the <a
988: href="https://man.openbsd.org/hostname.if.5">hostname.if(5)</a>
989: configuration file can now be a MAC address.
1.22 benno 990: <li>Limited display of wireguard peers by <a
991: href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a> to when
992: either a wireguard interface is specified or the flag "-A" is used.
993:
994: <li>Implemented the RFC 8781 PREF64 router advertisement option in
995: <a href="https://man.openbsd.org/rad.8">rad(8)</a> which is used to o
996: communicate NAT64 prefixes to hosts.
997:
998: <li>Moved the documentation of flag mappings displayed by "route show" from the <a
999: href="https://man.openbsd.org/netstat.1">netstat(1)</a> manpage to <a
1000: href="https://man.openbsd.org/route.8">route(8)</a>.
1001:
1002: <li>Improvements in <a href="https://man.openbsd.org/nc.1">nc(1)</a>:
1003: <ul>
1.27 jsg 1004: <li>Stop claiming connection success in UDP mode unless true.
1.22 benno 1005: <li>Do not test the connection in non-interactive mode. The test
1006: writes characters to the socket which can corrupt data that is
1007: possible piped into nc.
1008: </ul>
1009:
1010: <li>Added support for newlines inside the alternative names block in
1011: <a
1012: href="https://man.openbsd.org/acme-client.conf.5">acme-client.conf</a>.
1013: <li>Made <a
1014: href="https://man.openbsd.org/acme-client.1">acme-client(1)</a> use
1015: time checks which eliminate time-zone variation.
1016: <li>Encode Subject Alternative Name (SAN) entries before printing in <a
1017: href="https://man.openbsd.org/acme-client.1">acme-client(1)</a>.
1018: <li>Prevent <a
1019: href="https://man.openbsd.org/acme-client.1">acme-client(1)</a> from
1020: leaking an http get request when receiving a redirect without a
1021: location header.
1.21 benno 1022:
1.13 benno 1023: <!-- smtpd -->
1024: <li>Prevented <a href="https://man.openbsd.org/smtpd.8">smtpd(8)</a>
1025: abort due to a connection from a local, scoped ipv6 address.
1026: <li>Fixed a potential NULL dereference in the unpriv child expanding
1027: %{mda} in <a href="https://man.openbsd.org/smtpd.8">smtpd(8)</a>.
1028:
1029: <li>Corrected the order of arguments for calls to <a
1030: href="https://man.openbsd.org/shutdown.2">shutdown(2)</a> on the route
1031: socket of <a href="https://man.openbsd.org/slaacd.8">slaacd(8)</a>, <a
1032: href="https://man.openbsd.org/dhcpleased.8">dhcpleased(8)</a> and <a
1033: href="https://man.openbsd.org/unwind.8">unwind(8)</a>.
1034: <li>Made <a href="https://man.openbsd.org/route.8">route(8)</a>
1035: sourceaddr print the used addresses for inet and inet6, or "default"
1036: if no sourceaddr is set and the default algorithm is used.
1037: <li>Added -mpls option to the route(8) monitor command. It can be
1038: used to restrict displayed route messages to the mpls address family.
1039: <li>Fixed <a href="https://man.openbsd.org/openrsync.1">rsync(1)</a>
1040: handling of port numbers in rsync://host[:port]/module URLS.
1041: <li>Made <a href="https://man.openbsd.org/tcpdrop.8">tcpdrop(8)</a>
1042: accept netstat-style address.port syntax.
1043: <li>Ensured <a href="https://man.openbsd.org/pfctl.8">pfctl(8)</a>
1044: correctly adds addresses to the undefined/inactive table.
1.19 kn 1045: <li>Switched <a href="https://man.openbsd.org/tftpd.8">tftpd(8)</a> to default
1046: to read-only unless <code>-w</code> is specified for write access
1047: (the previous default).
1048: <li>Changed <a href="https://man.openbsd.org/rarpd.8">rarpd(8)</a> to only unveil /tftpboot if -t is specified.
1.22 benno 1049: <li>Fixed the DIOCIGETIFACES ioctl so all network interfaces and
1050: interface groups are reported in <a
1051: href="https://man.openbsd.org/pfctl.8">pfctl(8)</a>.
1052:
1.13 benno 1053:
1.1 benno 1054: </ul>
1055:
1056: <li><a href="https://man.openbsd.org/tmux.1">tmux(1)</a> improvements and bug fixes:
1057: <ul>
1.22 benno 1058: <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.
1059: <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.
1060: <li>Preserved the marked pane when renumbering windows in <a href="https://man.openbsd.org/tmux.1">tmux(1)</a>.

1.1 benno 1167: </ul>
1168: </ul>
1169:
1.14 benno 1170: <li>OpenSSH 9.3 and OpenSSH 9.2<br>
1171: This release of OpenBSD includes the changes made to OpenSSH since release 9.1:
1.1 benno 1172: <ul>
1173: <li>Security
1174: <ul>
1.14 benno 1175: <li>ssh-add(1): when adding smartcard keys to ssh-agent(1) with the
1176: per-hop destination constraints (ssh-add -h ...) added in OpenSSH
1177: 8.9, a logic error prevented the constraints from being
1178: communicated to the agent. This resulted in the keys being added
1179: without constraints. The common cases of non-smartcard keys and
1180: keys without destination constraints are unaffected. This problem
1181: was reported by Luci Stanescu.
1182: <li>ssh(1): Portable OpenSSH provides an implementation of the
1183: getrrsetbyname(3) function if the standard library does not
1184: provide it, for use by the VerifyHostKeyDNS feature. A
1185: specifically crafted DNS response could cause this function to
1186: perform an out-of-bounds read of adjacent stack data, but this
1187: condition does not appear to be exploitable beyond denial-of-
1188: service to the ssh(1) client.<br>
1189: The getrrsetbyname(3) replacement is only included if the system's
1190: standard library lacks this function and portable OpenSSH was not
1191: compiled with the ldns library (--with-ldns). getrrsetbyname(3) is
1192: only invoked if using VerifyHostKeyDNS to fetch SSHFP records. This
1193: problem was found by the Coverity static analyzer.
1194: <li>sshd(8): fix a pre-authentication double-free memory fault
1195: introduced in OpenSSH 9.1. This is not believed to be exploitable,
1196: and it occurs in the unprivileged pre-auth process that is
1197: subject to chroot(2) and is further sandboxed on most major
1198: platforms.
1199: <li>ssh(8): in OpenSSH releases after 8.7, the PermitRemoteOpen option
1200: would ignore its first argument unless it was one of the special
1201: keywords "any" or "none", causing the permission list to fail open
1202: if only one permission was specified. bz3515
1203: <li>ssh(1): if the CanonicalizeHostname and CanonicalizePermittedCNAMEs
1204: options were enabled, and the system/libc resolver did not check
1205: that names in DNS responses were valid, then use of these options
1206: could allow an attacker with control of DNS to include invalid
1207: characters (possibly including wildcards) in names added to
1208: known_hosts files when they were updated. These names would still
1209: have to match the CanonicalizePermittedCNAMEs allow-list, so
1210: practical exploitation appears unlikely.
1211: </ul>
1.1 benno 1212: <li>Potentially-incompatible changes
1.14 benno 1213: <ul>
1214: <li>ssh(1): add a new EnableEscapeCommandline ssh_config(5) option that
1215: controls whether the client-side ~C escape sequence that provides a
1216: command-line is available. Among other things, the ~C command-line
1217: could be used to add additional port-forwards at runtime.<br>
1218: This option defaults to "no", disabling the ~C command-line that
1219: was previously enabled by default. Turning off the command-line
1220: allows platforms that support sandboxing of the ssh(1) client
1221: (currently only OpenBSD) to use a stricter default sandbox policy.
1222: </ul>
1223: <li>New features
1224: <ul>
1225: <li>ssh-keygen(1), ssh-keyscan(1): accept -Ohashalg=sha1|sha256 when
1226: outputting SSHFP fingerprints to allow algorithm selection. bz3493
1227: <li>sshd(8): add a `sshd -G` option that parses and prints the
1228: effective configuration without attempting to load private keys
1229: and perform other checks. This allows usage of the option before
1230: keys have been generated and for configuration evaluation and
1231: verification by unprivileged users.
1232: <li>sshd(8): add support for channel inactivity timeouts via a new
1233: sshd_config(5) ChannelTimeout directive. This allows channels that
1234: have not seen traffic in a configurable interval to be
1235: automatically closed. Different timeouts may be applied to session,
1236: X11, agent and TCP forwarding channels.
1237: <li>sshd(8): add a sshd_config UnusedConnectionTimeout option to
1238: terminate client connections that have no open channels for a
1239: length of time. This complements the ChannelTimeout option above.
1240: <li>sshd(8): add a -V (version) option to sshd like the ssh client has.
1241: <li>ssh(1): add a "Host" line to the output of ssh -G showing the
1242: original hostname argument. bz3343
1243: <li>scp(1), sftp(1): add a -X option to both scp(1) and sftp(1) to
1244: allow control over some SFTP protocol parameters: the copy buffer
1245: length and the number of in-flight requests, both of which are used
1246: during upload/download. Previously these could be controlled in
1247: sftp(1) only. This makes them available in both SFTP protocol
1248: clients using the same option character sequence.
1249: <li>ssh-keyscan(1): allow scanning of complete CIDR address ranges,
1250: e.g. "ssh-keyscan 192.168.0.0/24". If a CIDR range is passed, then
1251: it will be expanded to all possible addresses in the range
1252: including the all-0s and all-1s addresses. bz#976
1253: <li>ssh(1): support dynamic remote port forwarding in escape
1254: command-line's -R processing. bz#3499
1255: </ul>
1.1 benno 1256: <li>Bugfixes
1.14 benno 1257: <ul>
1258: <li>scp(1), sftp(1): fix progressmeter corruption on wide displays;
1259: bz3534
1260: <li>ssh-add(1), ssh-keygen(1): use RSA/SHA256 when testing usability
1261: of private keys as some systems are starting to disable RSA/SHA1
1262: in libcrypto.
1263: <li>sftp-server(8): fix a memory leak. GHPR363
1.16 jsg 1264: <li>ssh(1), sshd(8), ssh-keyscan(1): remove vestigial protocol
1.14 benno 1265: compatibility code and simplify what's left.
1266: <li>Fix a number of low-impact Coverity static analysis findings.
1267: These include several reported via bz2687
1268: <li>ssh_config(5), sshd_config(5): mention that some options are not
1269: first-match-wins.
1270: <li>Rework logging for the regression tests. Regression tests will now
1271: capture separate logs for each ssh and sshd invocation in a test.
1272: <li>ssh(1): make `ssh -Q CASignatureAlgorithms` work as the manpage
1273: says it should; bz3532.
1274: <li>ssh(1): ensure that there is a terminating newline when adding a
1275: new entry to known_hosts; bz3529
1276: <li>ssh(1): when restoring non-blocking mode to stdio fds, restore
1277: exactly the flags that ssh started with and don't just clobber them
1278: with zero, as this could also remove the append flag from the set.
1279: bz3523
1280: <li>ssh(1): avoid printf("%s", NULL) if using UserKnownHostsFile=none
1281: and a hostkey in one of the system known hosts file changes.
1282: <li>scp(1): switch scp from using pipes to a socket-pair for
1283: communication with its ssh sub-processes, matching how sftp(1)
1284: operates.
1285: <li>sshd(8): clear signal mask early in main(); sshd may have been
1286: started with one or more signals masked (sigprocmask(2) is not
1287: cleared on fork/exec) and this could interfere with various things,
1288: e.g. the login grace timer. Execution environments that fail to
1289: clear the signal mask before running sshd are clearly broken, but
1290: apparently they do exist.
1291: <li>ssh(1): warn if no host keys for hostbased auth can be loaded.
1292: <li>sshd(8): Add server debugging for hostbased auth that is queued and
1293: sent to the client after successful authentication, but also logged
1294: to assist in diagnosis of HostbasedAuthentication problems. bz3507
1295: <li>ssh(1): document use of the IdentityFile option as being usable to
1296: list public keys as well as private keys. GHPR352
1297: <li>sshd(8): check for and disallow MaxStartups values less than or
1298: equal to zero during config parsing, rather than failing later at
1299: runtime. bz3489
1300: <li>ssh-keygen(1): fix parsing of hex cert expiry times specified on
1301: the command-line when acting as a CA.
1302: <li>scp(1): when scp(1) is using the SFTP protocol for transport (the
1303: default), better match scp/rcp's handling of globs that don't match
1304: the globbed characters but do match literally (e.g. trying to
1305: transfer a file named "foo.[1]"). Previously scp(1) in SFTP mode
1306: would not match these pathnames but legacy scp/rcp mode would.
1307: bz3488
1308: <li>ssh-agent(1): document the "-O no-restrict-websafe" command-line
1309: option.
1310: <li>ssh(1): honour user's umask(2) if it is more restrictive then the
1311: ssh default (022).

1608: <section id=sourcecode>
1609: <h3>Notes about the source code</h3>
1610: <p>
1611: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1612: This file contains everything you need except for the kernel sources,
1613: which are in a separate archive.
1614: To extract:
1615: <blockquote><pre>
1616: # <kbd>mkdir -p /usr/src</kbd>
1617: # <kbd>cd /usr/src</kbd>
1618: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1619: </pre></blockquote>
1620: <p>
1621: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1622: This file contains all the kernel sources you need to rebuild kernels.
1623: To extract:
1624: <blockquote><pre>
1625: # <kbd>mkdir -p /usr/src/sys</kbd>
1626: # <kbd>cd /usr/src</kbd>
1627: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1628: </pre></blockquote>
1629: <p>
1630: Both of these trees are a regular CVS checkout. Using these trees it
1631: is possible to get a head-start on using the anoncvs servers as
1632: described <a href="anoncvs.html">here</a>.
1633: Using these files
1634: results in a much faster initial CVS update than you could expect from
1635: a fresh checkout of the full OpenBSD source tree.

1641: <h3>Ports Tree</h3>
1642: <p>
1643: A ports tree archive is also provided. To extract:
1644: <blockquote><pre>
1645: # <kbd>cd /usr</kbd>
1646: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1647: </pre></blockquote>
1648: <p>
1649: Go read the <a href="faq/ports/index.html">ports</a> page
1650: if you know nothing about ports
1651: at this point. This text is not a manual of how to use ports.
1652: Rather, it is a set of notes meant to kickstart the user on the
1653: OpenBSD ports system.
1654: <p>
1655: The <i>ports/</i> directory represents a CVS checkout of our ports.
1656: As with our complete source tree, our ports tree is available via
1657: <a href="anoncvs.html">AnonCVS</a>.
1658: So, in order to keep up to date with the -stable branch, you must make
1659: the <i>ports/</i> tree available on a read-write medium and update the tree
1660: with a command like:
1661: <blockquote><pre>
1662: # <kbd>cd /usr/ports</kbd>
1663: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_3</kbd>
1664: </pre></blockquote>
1665: <p>
1666: [Of course, you must replace the server name here with a nearby anoncvs
1667: server.]
1668: <p>
1669: Note that most ports are available as packages on our mirrors. Updated
1670: ports for the 7.3 release will be made available if problems arise.
1671: <p>
1672: If you're interested in seeing a port added, would like to help out, or just
1673: would like to know more, the mailing list
1674: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
