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>.
1.1 benno 152: </ul>

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.
165: <li>Unlocked <a href="https://man.openbsd.org/ioctl.2">ioctl(2)</a>

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

274: href="https://man.openbsd.org/mimmutable.2">mimmutable(2)</a> and <a
275: href="https://man.openbsd.org/munmap.2">munmap(2)</a> reporting to <a
276: href="https://man.openbsd.org/kdump.1">kdump(1)</a>.
1.13 benno 277: <li>Added <a
278: href="https://man.openbsd.org/lastcomm.1">lastcomm(1)</a> reporting
279: for process kills due to <a
280: href="https://man.openbsd.org/execve.2">execve(2)</a> from non-pinned
281: syscall address
1.1 benno 282: </ul>
283:
284: <li>Various bugfixes and tweaks in userland:
285: <ul>
1.13 benno 286:
1.26 jsg 287: <li>Allow TZ to contain absolute paths starting with /usr/share/zoneinfo.
288: All absolute paths were ignored in 7.2 to avoid

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

314: href="https://man.openbsd.org/vi.1">vi(1)</a> ex_range.
315: <li>Corrected <a href="https://man.openbsd.org/top.1">top(1)</a>
316: display of online CPUs which can change based on the <a
317: href="https://man.openbsd.org/sysctl.2">sysctl(2)</a> sysctl setting.
1.13 benno 318: <li>Added support for a personal <a
319: href="https://man.openbsd.org/units.1">units(1)</a> library by passing
320: -f multiple times.
321:
322: <li>Made <a href="https://man.openbsd.org/rc.8">rc(8)</a> reorder
323: libraries in parallel to <a
324: href="https://man.openbsd.org/netstart.8">netstart(8)</a>, as this
325: does not depend on network access.
326:
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.
330:
1.13 benno 331: <li>Implemented periodic display in <a
332: href="https://man.openbsd.org/iostat.8">iostat(8)</a>.
333:
334: <li>Changed <a href="https://man.openbsd.org/df.1">df(1)</a> to
335: round up fractional percentages.
336:
337: <li>Added the <a
338: href="https://man.openbsd.org/audioctl.8">audioctl(8)</a> -w option to
339: display variables periodically.
340: <li>Added short options for <a
341: href="https://man.openbsd.org/timeout.1">timeout(1)</a> --foreground
342: and --preserve-status.<br>
343: Added signal as a full argument name for <a
344: href="https://man.openbsd.org/timeout.1">timeout(1)</a> -s.
345:
346: <li>Fixed .wav files generated by <a
1.22 benno 347: ; href="https://man.openbsd.org/aucat.1">aucat(1)</a> by using extended
1.13 benno 348: header format.
349: <li>In <a
350: href="https://man.openbsd.org/disklabel.8">disklabel(8)</a>, use the
351: size of the largest chunk of free space, not the total of all such
352: chunks, when checking for sufficient space to add a partition.
353: <li>Fixed unbounded variable expansion in <a
354: href="https://man.openbsd.org/pkg-config.1">pkg-config(1)</a>.
355: <li>Switched to use <a
356: href="https://man.openbsd.org/llvm-strip.1">llvm-strip(1)</a> on
357: architectures that use <a
358: href="https://man.openbsd.org/ld.lld.1">ld.lld(1)</a>.
359: <li>Extended <a
360: href="https://man.openbsd.org/disklabel.8">disklabel(8)</a> template
361: parsing to allow "[mount point] *" as the specification for putting
362: the maximum available free space into a partition, and extended
363: command line parsing to allow "T-" as the specification to read the
364: template from stdin.
365: <li>Fixed a number of out of bounds reads in DNS response parsing.
366:
1.1 benno 367: </ul>

1.1 benno 706: </ul>
707:
708: <li>Security improvements:
709: <ul>
1.23 benno 710: <li>Permissions (RWX, MAP_STACK, etc) on address space regions can
711: be made <a href="https://man.openbsd.org/mimmutable.2">immutable</a>,
712: so that <a href="https://man.openbsd.org/mmap.2">mmap(2)</a>, <a
713: href="https://man.openbsd.org/mprotect.2">mprotect(2)</a> or <a
714: href="https://man.openbsd.org/munmap.2">munmap(2)</a> fail with EPERM.
715: Most of the program static address space is now automatically
716: immutable (main program, ld.so, main stack, load-time shared
717: libraries, and dlopen()'d libraries mapped without RTLD_NODELETE).
718: Programmers can request non-immutable static data using the
719: "openbsd.mutable" section, or manually bring immutability to (page
720: aligned heap objects) using <a
721: href="https://man.openbsd.org/mimmutable.2">mimmutable(2)</a>.
722: <li>Some architectures now have non-readable code ("xonly"), both from
723: the perspective of userland reading its own memory, or the kernel
724: trying to read memory in a system call. Many sloppy practices in
725: userland code had to be repaired to allow this. The <a
726: href="https://man.openbsd.org/ld.lld.1">linker (ld.lld(1))</a> option
727: --execute-only is enabled by default. In order of development: arm64,
728: riscv64, hppa, amd64, powerpc64, powerpc (G5 only), octeon. sparc64
729: (sun4u only, unfinished).
730: <li>On all architectures which lack hardware-enforcement of xonly,
731: system calls are now prevented from reading (via <a
732: href="https://man.openbsd.org/copyin.9">copyin(9)</a>/copyinst)
733: inside the program's main text, ld.so text, sigtramp text, or libc.so
734: text.
735: <li>can still benefit from switching to --execute-only binaries if the
736: cpu generates different traps for instruction-fetch versus data-fetch.
737: The VM system will not allow memory to be read before it was executed
738: which is valuable together with library relinking. Architectures
739: switched over include loongson.
740: <li><a href="https://man.openbsd.org/ld.so.1">ld.so(1)</a> and crt0
741: register the location of the <a
742: href="https://man.openbsd.org/execve.2">execve(2)</a> stub with the
743: kernel using pinsyscall(2), after which the kernel only accepts an
744: execve call from that specific location.
1.13 benno 745: <li>Added <a href="https://man.openbsd.org/execve.2">execve(2)</a>
746: violations of <a
747: href="https://man.openbsd.org/pinsyscall.2">pinsyscall(2)</a> policy
748: to the daily mail, available by setting rc.conf.local(5)
749: accounting=YES.
1.23 benno 750: <li>Added retguard (consistency-check the return address on the
751: stack) to amd64 syscalls.
752: <li>sshd random relinking at boot: Randomly relink and install <a
753: href="https://man.openbsd.org/sshd.8">sshd(8)</a>, resulting
754: in a sshd binary with unknown address layout after every reboot.
1.13 benno 755: <li>Add another mitigation against classic BROP on systems without
756: execute-only mmu hardware-enforcement. A range-checking wrapper in
1.23 benno 757: front of <a href="https://man.openbsd.org/copyin.9">copyin(9)</a> and
758: href="https://man.openbsd.org/copyinstr.9">copyinstr(9)</a> ensures
759: the userland source address doesn't overlap the main program text and
760: other text segments, thereby making this address ranges unreadable to
761: the kernel. No programs have been discovered which require reading
762: their own text segments with a system call.
1.22 benno 763: <li>On arm64, introduce mitigation of the Spectre-BHB (Branch
764: History Injection) CPU vulnerability by using core-specific trampoline
765: vectors.
1.23 benno 766: <li>Enabled the arm64 Data Independent Timing (DIT) feature in both the kernel and
767: userland on CPUs that support it to mitigate timing side-channel
1.22 benno 768: attacks.
1.1 benno 769: </ul>
770:
771: <li>Changes in the network stack:
772: <ul>
1.13 benno 773:
1.24 jsg 774: <li>Made /dev/pf a clonable device to better track kernel resources
1.22 benno 775: used by processes.
776: <li>Modified TCP receive buffer size auto-scaling to use the smoothed
777: RTT (SRTT) instead of the timestamp option, which improves performance
778: on high latency networks if the timestamp option isn't available.
1.24 jsg 779: <li>Relaxed the requirement for multicast support of interfaces for
1.22 benno 780: configuring IPv6. This allows non-multicast interfaces such as
781: point-to-point interfaces and the NBMA / point-to-multipoint
782: interfaces like mpe(4), mgre(4) and wg(4) to work with IPv6.
783: <li>Use the new <a
784: href="https://man.openbsd.org/getnsecruntime.9">getnsecruntime(9)</a>
785: timer to check the TCP_KEEPALIVE timer only against the system
786: runtime, not the uptime. Prevents TCP connections to fail after
1.24 jsg 787: waking up from suspend.
1.13 benno 788: <li>Used stoeplitz (symmetric Toeplitz hash algorithm) to generate a
789: hash/flowid for <a href="https://man.openbsd.org/pf.4">pf(4)</a> state
790: keys. With this change, pf will hash traffic the same way that
791: hardware using a stoeplitz key will hash incoming traffic on rings.
1.27 jsg 792: stoeplitz is also used by the TCP stack to generate a flow id, which
1.13 benno 793: is used to pick which transmit ring is used on nics with multiple
794: queues too. using the same algorithm throughout the stack encourages
795: affinity of packets to rings and softnet threads the whole way
796: through.
797: <li>Prevented possible kernel crashes by dropping TCP packets with
798: destination port 0 in <a href="https://man.openbsd.org/pf.4">pf(4)</a>
799: and the stack.
800: <li>Fixed a endian swap bug causing problems with <a
1.27 jsg 801: href="https://man.openbsd.org/vlan.4">vlan(4)</a> on <a
1.13 benno 802: href="https://man.openbsd.org/em.4">em(4)</a> sparc64 systems.
803: <li>Denied "pipex no" tunnel setting for <a
804: href="https://man.openbsd.org/pppx.4">pppx(4)</a> interfaces.
1.22 benno 805: <li>Fixed <a href="https://man.openbsd.org/pfsync.4">pfsync(4)</a>
806: crashing on pf_state_key removal.
1.13 benno 807: <li>Fixed a panic in <a
808: href="https://man.openbsd.org/pfsync.4">pfsync(4)</a> when there are
809: no data ready for bulk transfer.
810: <li>Turned off TCP Segmentation Offload (TSO) if interface is added
811: to layer 2 devices.
812: <li>Improved <a href="https://man.openbsd.org/vnet.4">vnet(4)</a>
813: to work better in busy conditions.
814: <li>Added a <a href="https://man.openbsd.org/bpf.4">bpf(4)</a> timeout
815: (BIOCSWTIMEOUT) between capturing a packet and making the buffer
816: readable, preventing for example <a
817: href="https://man.openbsd.org/pflogd.8">pflogd(8)</a> waking every
818: half second even if there is nothing to read. By default this buffer
819: is infinite and must be filled to become readable.
820: <li>Avoided enabling TSO on interfaces which are already attached to a bridge.
821: </ul>
1.1 benno 822:
823: <li>Routing daemons and other userland network improvements:
824: <ul>
825: <li>IPsec support was improved:
826: <ul>
1.13 benno 827: <li>Added <a href="https://man.openbsd.org/iked.8">iked(8)</a>
828: support for configuring multiple name servers.
829: <li>Synced proc.c from <a
830: href="https://man.openbsd.org/vmd.8">vmd(8)</a> to <a
831: href="https://man.openbsd.org/iked.8">iked(8)</a> to enabled fork +
832: exec for all processes. This gives each process a fresh and unique
833: address space to further improve randomization of ASLR and stack
834: protector.
835: </ul>
836:
837: <li>In <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>, <a
838: href="https://man.openbsd.org/bgpctl.8">bgpctl(8)</a> and <a
839: href="https://man.openbsd.org/bgplgd.8">bgplgd(8)</a>:
840: <ul>
841: <li>Improved performance by optimising the output filters
1.16 jsg 842: <li>Add Autonomous System Provider Authorization (ASPA) validation
1.13 benno 843: based on draft-ietf-sidrops-aspa-verification-12
844: <li>Introduce avs (ASPA validation state) filter and bgpctl
845: filter argument
846: <li>Add ASPA support for the RTR protocol based on
847: draft-ietf-sidrops-8210bis-10
848: <li>Improve open policy (RFC 9234) support and enable the capability
849: automatically if a role is specified for the peer
850: <li>Introduce a per neighbor 'role' configuration option to specify
851: the session role used by ASPA verification and the open policy
852: capability. The 'announce policy' statement was simplified at
853: the same time.
854: <li>Improve startup behaviour by introducing a small delay before
855: opening the connection to a new peer
856: <li>Support for aspa-set table config which can be provided by
857: <a
858: href="https://man.openbsd.org/rpki-client.8">rpki-client(8)</a>
859: <li>Make it possible to filter the RIB by invalid and leaked prefixes
860: in bgpctl and bgplgd
861: <li>Add OpenMetrics output to bgpctl for various BGP statistics and
862: add /metrics endpoint to bgplgd
863: <li>Fix of incorrect length checks that allowed an out-of-bounds
864: read in bgpd.
1.1 benno 865: </ul>
866: <li><a href="https://man.openbsd.org/rpki-client.8">rpki-client(8)</a> saw some changes:
867: <ul>
1.13 benno 868: <li>Add a new '-H' command line option to create a shortlist of
869: repositories to synchronize to. For example, when invoking
870: "rpki-client -H rpki.ripe.net -H chloe.sobornost.net", the utility
871: will not connect to any other hosts other than the two specified
872: through the -H option.
873: <li>Add support for validating Geofeed (RFC 9092) authenticators. To
874: see an example download https://sobornost.net/geofeed.csv and run
875: "rpki-client -f geofeed.csv"
876: <li>Add support for validating Trust Anchor Key (TAK) objects. TAK
877: objects can be used to produce new Trust Anchor Locators (TALs) signed
878: by and verified against the previous Trust Anchor. See
879: draft-ietf-sidrops-signed-tal for the full specification.
880: <li>Log lines related to RRDP/HTTPS connection problems now include the
881: IP address of the problematic endpoint (in brackets).
882: <li>Improve the error message when an invalid filename is encountered
883: in the rpkiManifest field in the Subject Access Information (SIA)
884: extension.
885: <li>Emit a warning when unexpected X.509 extensions are encountered.
886: <li>Restrict the ROA ipAddrBlocks field to only allow two
887: ROAIPAddressFamily structures (one per address family). See
888: draft-ietf-sidrops-rfc6482bis.
889: <li>Check the absence of the Path Length constraint in the Basic
890: Constraints extension.
891: <li>Restrict the SIA extension to only allow the signedObject and
892: rpkiNotify accessMethods.
893: <li>Check that the Signed Object access method is present in ROA, MFT,
894: ASPA, TAK, and GBR End-Entity certificates.
895: <li>In addition to the 'rsync://' scheme, also permit other schemes
896: (such as 'https://') in the SIA signedObject access method.
897: <li>Check that the KeyUsage extension is set to nothing but
898: digitalSignature on End-Entity certificates.
1.16 jsg 899: <li>Check that the KeyUsage extension is set to nothing but keyCertSign
1.13 benno 900: and CRLSign on CA certificates.
901: <li>Check that the ExtendedKeyUsage extension is absent on CA
902: certificates.
903: <li>Fix a bug in the handling of the port of http_proxy.
904: <li>The '-r' command line option has been deprecated.
905: <li>Filemode (-f) output is now presented as a text based table.
906: <li>The 'expires' key in the JSON/CSV/OpenBGPD output formats is now
907: calculated with more accuracy. The calculation takes into account the
908: nextUpdate value of all intermediate CRLs in the signature path
909: towards the trust anchor, in addition to the expiry moment of the
910: leaf-CRL and CAs.
911: <li>Handling of CRLs and Manifests in the face of inconsistent RRDP delta
912: publications has been improved. A copy of an alternative version of
913: the applicable CRL is kept in the staging area of the cache directory,
914: in order to increase the potential for establishing a complete
915: publication point, in cases where a single publication point update
916: was smeared across multiple RRDP delta files.
917: <li>The OpenBGPD configuration output now includes validated Autonomous
918: System Provider Authorization (ASPA) payloads as an 'aspa-set {}'
919: configuration block.
920: <li>When rpki-client is invoked with increased verbosity ('-v'), the
921: current RRDP Serial & Session ID are shown to aid debugging.
922: <li>Self-signed X.509 certificates (such as Trust Anchor certificates)
923: now are considered invalid if they contain an X.509
924: AuthorityInfoAccess extension.
925: <li>Signed Objects where the CMS signing-time attribute contains a
926: timestamp later then the X.509 certificate's notAfter timestamp are
927: considered invalid.
928: <li>Manifests where the CMS signing-time attribute contains a timestamp
929: later then the Manifest eContent nextUpdate timestamp are considered
930: invalid.
931: <li>Any objects whose CRL Distribution Points extension contains a
932: CRLIssuer, CRL Reasons, or nameRelativeToCRLIssuer field are
933: considered invalid in accordance with RFC 6487 section 4.8.6.
934: <li>For every X.509 certificate the SHA-1 of the Subject Public Key is
935: calculated and compared to the Subject Key Identifier (SKI), if a
936: mismatch is found the certificate is not trusted.
937: <li>Require the outside-TBS signature OID for every X.509 intermediate
938: CA certificate and CRL to be sha256WithRSAEncryption.
939: <li>Require the RSA key pair modulus and public exponent parameters to
940: strictly conform to the RFC 7935 profile.
941: <li>Ensure there is no trailing garbage present in Signed Objects beyond
942: the self-embedded length field.
943: <li>Require RRDP Session IDs to strictly be version 4 UUIDs.
944: <li>When decoding and validating an individual RPKI file using filemode
945: (rpki-client -f file), display the signature path towards the trust
946: anchor, and the timestamp when the signature path will expire.
947: <li>When decoding and validating an individual RPKI file using filemode
948: (rpki-client -f file), display the optional CMS signing-time, and
949: non-optional X.509 notBefore, and X.509 notAfter timestamps.
1.1 benno 950: </ul>
951:
1.22 benno 952: <li>Switched <a href="https://man.openbsd.org/tftpd.8">tftpd(8)</a> to
953: default to read-only unless -w is specified for write access (the
954: previous default).
955: <li>Stopped printing the prompt for non-interactive usage of <a
956: href="https://man.openbsd.org/tftp.1">tftp(1)</a>.
957: <li>Changed <a href="https://man.openbsd.org/rarpd.8">rarpd(8)</a> to
958: only unveil /tftpboot if -t is specified.
959: <li>Added client certificate authentication and an optional SASL
960: EXTERNAL bind to <a
961: href="https://man.openbsd.org/ypldap.8">ypldap(8)</a>.
962: <li>Adjusted ipv6 address width to align the display columns better
963: in the output of <a href="https://man.openbsd.org/ndp.8">ndp(8)</a>,
964: <a href="https://man.openbsd.org/route.8">route(8)</a> and <a
965: href="https://man.openbsd.org/netstat.1">netstat(1)</a> as already
966: available in <a
967: href="https://man.openbsd.org/systat.1">systat(1)</a>'s netstat.
968: <li>Used <a href="https://man.openbsd.org/stravis.3">stravis(3)</a> to
969: sanitize redirect URIs from <a
970: href="https://man.openbsd.org/ftp.1">ftp(1)</a> fetch before printing.
971: <li>Prevent an <a
1.27 jsg 972: href="https://man.openbsd.org/unwind.8">unwind(8)</a> crash when a TCP
1.22 benno 973: query is larger than the length field indicated.
974:
975: <li>Preserve the original order of nameservers as configured via <a
976: href="https://man.openbsd.org/resolv.conf.5">resolv.conf(5)</a> in <a
977: href="https://man.openbsd.org/resolvd.8">resolvd(8)</a>.
978:
979: <li>Restrict the characters allowed in the hostname argument of <a
980: href="https://man.openbsd.org/getaddrinfo.3">getaddrinfo(3)</a> to the
981: set [A-z0-9-_.]. Additionally two consecutive dots ('.') are not
982: allowed nor can the string start with - or '.'. This removes
983: characters like '$', '`', '\n' or '*' that can traverse the DNS
984: without problems, but have special meaning, for example a shell.
985:
986: <li>Added <a
987: href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a> -M (mac) to
988: find the mac address on an interface and print it.
1.21 benno 989: <li>Added support for configuring interfaces by lladdr to support
1.27 jsg 990: interface configurations bound to a specific hardware device. The "if"
1.21 benno 991: part of the <a
992: href="https://man.openbsd.org/hostname.if.5">hostname.if(5)</a>
993: configuration file can now be a MAC address.
1.22 benno 994: <li>Limited display of wireguard peers by <a
995: href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a> to when
996: either a wireguard interface is specified or the flag "-A" is used.
997:
998: <li>Implemented the RFC 8781 PREF64 router advertisement option in
999: <a href="https://man.openbsd.org/rad.8">rad(8)</a> which is used to o
1000: communicate NAT64 prefixes to hosts.
1001:
1002: <li>Moved the documentation of flag mappings displayed by "route show" from the <a
1003: href="https://man.openbsd.org/netstat.1">netstat(1)</a> manpage to <a
1004: href="https://man.openbsd.org/route.8">route(8)</a>.
1005:
1006: <li>Improvements in <a href="https://man.openbsd.org/nc.1">nc(1)</a>:
1007: <ul>
1.27 jsg 1008: <li>Stop claiming connection success in UDP mode unless true.
1.22 benno 1009: <li>Do not test the connection in non-interactive mode. The test
1010: writes characters to the socket which can corrupt data that is
1011: possible piped into nc.
1012: </ul>
1013:
1014: <li>Added support for newlines inside the alternative names block in
1015: <a
1016: href="https://man.openbsd.org/acme-client.conf.5">acme-client.conf</a>.
1017: <li>Made <a
1018: href="https://man.openbsd.org/acme-client.1">acme-client(1)</a> use
1019: time checks which eliminate time-zone variation.
1020: <li>Encode Subject Alternative Name (SAN) entries before printing in <a
1021: href="https://man.openbsd.org/acme-client.1">acme-client(1)</a>.
1022: <li>Prevent <a
1023: href="https://man.openbsd.org/acme-client.1">acme-client(1)</a> from
1024: leaking an http get request when receiving a redirect without a
1025: location header.
1.21 benno 1026:
1.13 benno 1027: <!-- smtpd -->
1028: <li>Prevented <a href="https://man.openbsd.org/smtpd.8">smtpd(8)</a>
1029: abort due to a connection from a local, scoped ipv6 address.
1030: <li>Fixed a potential NULL dereference in the unpriv child expanding
1031: %{mda} in <a href="https://man.openbsd.org/smtpd.8">smtpd(8)</a>.
1032:
1033: <li>Corrected the order of arguments for calls to <a
1034: href="https://man.openbsd.org/shutdown.2">shutdown(2)</a> on the route
1035: socket of <a href="https://man.openbsd.org/slaacd.8">slaacd(8)</a>, <a
1036: href="https://man.openbsd.org/dhcpleased.8">dhcpleased(8)</a> and <a
1037: href="https://man.openbsd.org/unwind.8">unwind(8)</a>.
1038: <li>Made <a href="https://man.openbsd.org/route.8">route(8)</a>
1039: sourceaddr print the used addresses for inet and inet6, or "default"
1040: if no sourceaddr is set and the default algorithm is used.
1041: <li>Added -mpls option to the route(8) monitor command. It can be
1042: used to restrict displayed route messages to the mpls address family.
1043: <li>Fixed <a href="https://man.openbsd.org/openrsync.1">rsync(1)</a>
1044: handling of port numbers in rsync://host[:port]/module URLS.
1045: <li>Made <a href="https://man.openbsd.org/tcpdrop.8">tcpdrop(8)</a>
1046: accept netstat-style address.port syntax.
1047: <li>Ensured <a href="https://man.openbsd.org/pfctl.8">pfctl(8)</a>
1048: correctly adds addresses to the undefined/inactive table.
1.19 kn 1049: <li>Switched <a href="https://man.openbsd.org/tftpd.8">tftpd(8)</a> to default
1050: to read-only unless <code>-w</code> is specified for write access
1051: (the previous default).
1052: <li>Changed <a href="https://man.openbsd.org/rarpd.8">rarpd(8)</a> to only unveil /tftpboot if -t is specified.
1.22 benno 1053: <li>Fixed the DIOCIGETIFACES ioctl so all network interfaces and
1054: interface groups are reported in <a
1055: href="https://man.openbsd.org/pfctl.8">pfctl(8)</a>.
1056:
1.13 benno 1057:
1.1 benno 1058: </ul>
1059:
1060: <li><a href="https://man.openbsd.org/tmux.1">tmux(1)</a> improvements and bug fixes:
1061: <ul>

1.1 benno 1171: </ul>
1172: </ul>
1173:
1.14 benno 1174: <li>OpenSSH 9.3 and OpenSSH 9.2<br>
1175: This release of OpenBSD includes the changes made to OpenSSH since release 9.1:
1.1 benno 1176: <ul>
1177: <li>Security
1178: <ul>
1.14 benno 1179: <li>ssh-add(1): when adding smartcard keys to ssh-agent(1) with the
1180: per-hop destination constraints (ssh-add -h ...) added in OpenSSH
1181: 8.9, a logic error prevented the constraints from being
1182: communicated to the agent. This resulted in the keys being added
1183: without constraints. The common cases of non-smartcard keys and
1184: keys without destination constraints are unaffected. This problem
1185: was reported by Luci Stanescu.
1186: <li>ssh(1): Portable OpenSSH provides an implementation of the
1187: getrrsetbyname(3) function if the standard library does not
1188: provide it, for use by the VerifyHostKeyDNS feature. A
1189: specifically crafted DNS response could cause this function to
1190: perform an out-of-bounds read of adjacent stack data, but this
1191: condition does not appear to be exploitable beyond denial-of-
1192: service to the ssh(1) client.<br>
1193: The getrrsetbyname(3) replacement is only included if the system's
1194: standard library lacks this function and portable OpenSSH was not
1195: compiled with the ldns library (--with-ldns). getrrsetbyname(3) is
1196: only invoked if using VerifyHostKeyDNS to fetch SSHFP records. This
1197: problem was found by the Coverity static analyzer.
1198: <li>sshd(8): fix a pre-authentication double-free memory fault
1199: introduced in OpenSSH 9.1. This is not believed to be exploitable,
1200: and it occurs in the unprivileged pre-auth process that is
1201: subject to chroot(2) and is further sandboxed on most major
1202: platforms.
1203: <li>ssh(8): in OpenSSH releases after 8.7, the PermitRemoteOpen option
1204: would ignore its first argument unless it was one of the special
1205: keywords "any" or "none", causing the permission list to fail open
1206: if only one permission was specified. bz3515
1207: <li>ssh(1): if the CanonicalizeHostname and CanonicalizePermittedCNAMEs
1208: options were enabled, and the system/libc resolver did not check
1209: that names in DNS responses were valid, then use of these options
1210: could allow an attacker with control of DNS to include invalid
1211: characters (possibly including wildcards) in names added to
1212: known_hosts files when they were updated. These names would still
1213: have to match the CanonicalizePermittedCNAMEs allow-list, so
1214: practical exploitation appears unlikely.
1215: </ul>
1.1 benno 1216: <li>Potentially-incompatible changes
1.14 benno 1217: <ul>
1218: <li>ssh(1): add a new EnableEscapeCommandline ssh_config(5) option that
1219: controls whether the client-side ~C escape sequence that provides a
1220: command-line is available. Among other things, the ~C command-line
1221: could be used to add additional port-forwards at runtime.<br>
1222: This option defaults to "no", disabling the ~C command-line that
1223: was previously enabled by default. Turning off the command-line
1224: allows platforms that support sandboxing of the ssh(1) client
1225: (currently only OpenBSD) to use a stricter default sandbox policy.
1226: </ul>
1227: <li>New features
1228: <ul>
1229: <li>ssh-keygen(1), ssh-keyscan(1): accept -Ohashalg=sha1|sha256 when
1230: outputting SSHFP fingerprints to allow algorithm selection. bz3493
1231: <li>sshd(8): add a `sshd -G` option that parses and prints the
1232: effective configuration without attempting to load private keys
1233: and perform other checks. This allows usage of the option before
1234: keys have been generated and for configuration evaluation and
1235: verification by unprivileged users.
1236: <li>sshd(8): add support for channel inactivity timeouts via a new
1237: sshd_config(5) ChannelTimeout directive. This allows channels that
1238: have not seen traffic in a configurable interval to be
1239: automatically closed. Different timeouts may be applied to session,
1240: X11, agent and TCP forwarding channels.
1241: <li>sshd(8): add a sshd_config UnusedConnectionTimeout option to
1242: terminate client connections that have no open channels for a
1243: length of time. This complements the ChannelTimeout option above.
1244: <li>sshd(8): add a -V (version) option to sshd like the ssh client has.
1245: <li>ssh(1): add a "Host" line to the output of ssh -G showing the
1246: original hostname argument. bz3343
1247: <li>scp(1), sftp(1): add a -X option to both scp(1) and sftp(1) to
1248: allow control over some SFTP protocol parameters: the copy buffer
1249: length and the number of in-flight requests, both of which are used
1250: during upload/download. Previously these could be controlled in
1251: sftp(1) only. This makes them available in both SFTP protocol
1252: clients using the same option character sequence.
1253: <li>ssh-keyscan(1): allow scanning of complete CIDR address ranges,
1254: e.g. "ssh-keyscan 192.168.0.0/24". If a CIDR range is passed, then
1255: it will be expanded to all possible addresses in the range
1256: including the all-0s and all-1s addresses. bz#976
1257: <li>ssh(1): support dynamic remote port forwarding in escape
1258: command-line's -R processing. bz#3499
1259: </ul>
1.1 benno 1260: <li>Bugfixes
1.14 benno 1261: <ul>
1262: <li>scp(1), sftp(1): fix progressmeter corruption on wide displays;
1263: bz3534
1264: <li>ssh-add(1), ssh-keygen(1): use RSA/SHA256 when testing usability
1265: of private keys as some systems are starting to disable RSA/SHA1
1266: in libcrypto.
1267: <li>sftp-server(8): fix a memory leak. GHPR363
1.16 jsg 1268: <li>ssh(1), sshd(8), ssh-keyscan(1): remove vestigial protocol
1.14 benno 1269: compatibility code and simplify what's left.
1270: <li>Fix a number of low-impact Coverity static analysis findings.
1271: These include several reported via bz2687
1272: <li>ssh_config(5), sshd_config(5): mention that some options are not
1273: first-match-wins.
1274: <li>Rework logging for the regression tests. Regression tests will now
1275: capture separate logs for each ssh and sshd invocation in a test.
1276: <li>ssh(1): make `ssh -Q CASignatureAlgorithms` work as the manpage
1277: says it should; bz3532.
1278: <li>ssh(1): ensure that there is a terminating newline when adding a
1279: new entry to known_hosts; bz3529
1280: <li>ssh(1): when restoring non-blocking mode to stdio fds, restore
1281: exactly the flags that ssh started with and don't just clobber them
1282: with zero, as this could also remove the append flag from the set.
1283: bz3523
1284: <li>ssh(1): avoid printf("%s", NULL) if using UserKnownHostsFile=none
1285: and a hostkey in one of the system known hosts file changes.
1286: <li>scp(1): switch scp from using pipes to a socket-pair for
1287: communication with its ssh sub-processes, matching how sftp(1)
1288: operates.
1289: <li>sshd(8): clear signal mask early in main(); sshd may have been
1290: started with one or more signals masked (sigprocmask(2) is not
1291: cleared on fork/exec) and this could interfere with various things,
1292: e.g. the login grace timer. Execution environments that fail to
1293: clear the signal mask before running sshd are clearly broken, but
1294: apparently they do exist.
1295: <li>ssh(1): warn if no host keys for hostbased auth can be loaded.
1296: <li>sshd(8): Add server debugging for hostbased auth that is queued and
1297: sent to the client after successful authentication, but also logged
1298: to assist in diagnosis of HostbasedAuthentication problems. bz3507
1299: <li>ssh(1): document use of the IdentityFile option as being usable to
1300: list public keys as well as private keys. GHPR352
1301: <li>sshd(8): check for and disallow MaxStartups values less than or
1302: equal to zero during config parsing, rather than failing later at
1303: runtime. bz3489
1304: <li>ssh-keygen(1): fix parsing of hex cert expiry times specified on
1305: the command-line when acting as a CA.
1306: <li>scp(1): when scp(1) is using the SFTP protocol for transport (the
1307: default), better match scp/rcp's handling of globs that don't match
1308: the globbed characters but do match literally (e.g. trying to
1309: transfer a file named "foo.[1]"). Previously scp(1) in SFTP mode
1310: would not match these pathnames but legacy scp/rcp mode would.
1311: bz3488
1312: <li>ssh-agent(1): document the "-O no-restrict-websafe" command-line
1313: option.
1314: <li>ssh(1): honour user's umask(2) if it is more restrictive then the
1315: ssh default (022).

1612: <section id=sourcecode>
1613: <h3>Notes about the source code</h3>
1614: <p>
1615: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1616: This file contains everything you need except for the kernel sources,
1617: which are in a separate archive.
1618: To extract:
1619: <blockquote><pre>
1620: # <kbd>mkdir -p /usr/src</kbd>
1621: # <kbd>cd /usr/src</kbd>
1622: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1623: </pre></blockquote>
1624: <p>
1625: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1626: This file contains all the kernel sources you need to rebuild kernels.
1627: To extract:
1628: <blockquote><pre>
1629: # <kbd>mkdir -p /usr/src/sys</kbd>
1630: # <kbd>cd /usr/src</kbd>
1631: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1632: </pre></blockquote>
1633: <p>
1634: Both of these trees are a regular CVS checkout. Using these trees it
1635: is possible to get a head-start on using the anoncvs servers as
1636: described <a href="anoncvs.html">here</a>.
1637: Using these files
1638: results in a much faster initial CVS update than you could expect from
1639: a fresh checkout of the full OpenBSD source tree.

1645: <h3>Ports Tree</h3>
1646: <p>
1647: A ports tree archive is also provided. To extract:
1648: <blockquote><pre>
1649: # <kbd>cd /usr</kbd>
1650: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1651: </pre></blockquote>
1652: <p>
1653: Go read the <a href="faq/ports/index.html">ports</a> page
1654: if you know nothing about ports
1655: at this point. This text is not a manual of how to use ports.
1656: Rather, it is a set of notes meant to kickstart the user on the
1657: OpenBSD ports system.
1658: <p>
1659: The <i>ports/</i> directory represents a CVS checkout of our ports.
1660: As with our complete source tree, our ports tree is available via
1661: <a href="anoncvs.html">AnonCVS</a>.
1662: So, in order to keep up to date with the -stable branch, you must make
1663: the <i>ports/</i> tree available on a read-write medium and update the tree
1664: with a command like:
1665: <blockquote><pre>
1666: # <kbd>cd /usr/ports</kbd>
1667: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_3</kbd>
1668: </pre></blockquote>
1669: <p>
1670: [Of course, you must replace the server name here with a nearby anoncvs
1671: server.]
1672: <p>
1673: Note that most ports are available as packages on our mirrors. Updated
1674: ports for the 7.3 release will be made available if problems arise.
1675: <p>
1676: If you're interested in seeing a port added, would like to help out, or just
1677: would like to know more, the mailing list
1678: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
