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

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

! 207: when using the Xorg modesetting driver.
! 208:
1.1 benno 209: </ul>
210:
211: <li>VMM/VMD improvements
212: <ul>
1.13 benno 213:
1.22 ! benno 214: <li>Updated <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> to
! 215: allow guests to read MSR_HWCR and MSR_PSTATEDEF, which is necessary to
! 216: determine the TSC frequency on AMD families 17h and 19h.
! 217: <li>Allocated reference for vm and vcpu SLISTs in <a
! 218: href="https://man.openbsd.org/vmm.4">vmm(4)</a>, keeping vmm from
! 219: triggering excessive wakeup calls while iterating through the list of
! 220: vms while servicing an <a
! 221: href="https://man.openbsd.org/ioctl.2">ioctl(2)</a>.
! 222: <li>Set <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> RAX guest
! 223: register state based on VMCB.
! 224: <li>Removed locking in <a
! 225: href="https://man.openbsd.org/vmm.4">vmm(4)</a> vmm_intr_pending,
! 226: reducing slowdowns due to requests for a lock held while the VM is
! 227: running.
! 228: <li>Increased speed of delivery of interrupts to a running vcpu in <a
! 229: href="https://man.openbsd.org/vmm.4">vmm(4)</a>.
! 230: <li>Made <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> treat vcpu
! 231: lists as immutable, removing the need to reference count individual
! 232: vcpu objects and use a rwlock.
1.13 benno 233: <li>Implemented zero-copy operations on virtqueues in <a
234: href="https://man.openbsd.org/vmd.8">vmd(8)</a>.
235: <li>Provided a detailed e820 memory map when booting <a
236: href="https://man.openbsd.org/vmd.8">vmd(8)</a> guests with SeaBIOS.
237: When a vm initializes memory ranges, we now track what each range
238: represents. This information can be used to supply the e820 memory map
239: to SeaBIOS via the fw_cfg interface allowing it to properly
240: communicate memory ranges to a guest operating system. With this
241: special cases in ports can be removed.
242:
243: <li>Added thread names to vm processes in <a
244: href="https://man.openbsd.org/vmd.8">vmd(8)</a>, visible in <a
245: href="https://man.openbsd.org/ps.1">ps(1)</a>.
246: <li>Hid the WAITPKG cpu feature from <a
247: href="https://man.openbsd.org/vmm.4">vmm(4)</a> guests, preventing
248: invalid instruction exceptions. Also added WAITPKG feature
249: identification to i386 and amd64.
250:
251: <li>Changed <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> to
252: only open /dev/vmm once, having the parent process send the fd to the
253: vmm child process.
254: <li>Restricted <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> exposed cpuid extended feature flags.
255: <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.
256: <li>Stopped being paranoid about hypervisor correct PKU handling.<br>
257: Added saving and restoring guest PKRU to <a
258: href="https://man.openbsd.org/vmm.4">vmm(4)</a>. Expose the PKU cpuid
259: bit to the guest if in use on the host.
260: <li>Made <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> scan the pci bus to determine bootorder strings.
1.1 benno 261: </ul>
262:
263: <li>Various new userland features:
264: <ul>
1.13 benno 265:
1.22 ! benno 266:
! 267: <li>Added <a href="https://man.openbsd.org/kdump.1">kdump(1)</a>
! 268: argument support for msyscall, pledge, unveil, __realpath, ypconnect
! 269: and __tmpfd.
! 270: <li>Added <a
! 271: href="https://man.openbsd.org/mimmutable.2">mimmutable(2)</a> and <a
! 272: href="https://man.openbsd.org/munmap.2">munmap(2)</a> reporting to <a
! 273: href="https://man.openbsd.org/kdump.1">kdump(1)</a>.
1.13 benno 274: <li>Added <a
275: href="https://man.openbsd.org/lastcomm.1">lastcomm(1)</a> reporting
276: for process kills due to <a
277: href="https://man.openbsd.org/execve.2">execve(2)</a> from non-pinned
278: syscall address
1.1 benno 279: </ul>
280:
281: <li>Various bugfixes and tweaks in userland:
282: <ul>
1.13 benno 283:
1.22 ! benno 284: <li>The libc functions that use the zoneinfo database to convert
! 285: time between different timezones allowed the TY environment variable
! 286: to point to any file on the system to be reas as zoneinfo file. This
! 287: was restricted to paths starting with /usr/share/zoneinfo in the TZ
! 288: environement variable. Reject other absolute paths in TZ. The
! 289: assumption is that zoneinfo files under /usr/share/zoneinfo are
! 290: trustworthy, but
! 291:
! 292:
! 293: <li>Made <a href="https://man.openbsd.org/ldomctl.8">ldomctl(8)</a>
! 294: accept more descriptive name-based paths in addition to number-based
! 295: paths in <a
! 296: href="https://man.openbsd.org/ldom.conf.5">ldom.conf(5)</a>.
! 297: <li>Dropped support for $rc_exec in <a
! 298: href="https://man.openbsd.org/rc.subr.8">rc.subr(8)</a>. The rc_exec
! 299: function should be used instead.
! 300: <li>Excluded /tmp/*.shm files from /tmp cleaning in <a
! 301: href="https://man.openbsd.org/daily.8">daily(8)</a>. Removing them
! 302: interferes with programs that use shared memory via <a
! 303: href="https://man.openbsd.org/shm_open.3">shm_open(3)</a>.
! 304: <li>Added zap-to-char and zap-up-to-char to <a
! 305: href="https://man.openbsd.org/mg.1">mg(1)</a>. Bound zap-to-char to
! 306: M-z.
! 307: <li>Added support to <a
! 308: href="https://man.openbsd.org/gunzip.1">gunzip(1)</a> for zip files
! 309: that contain a single member.
! 310: <li>Fixed <a href="https://man.openbsd.org/ed.1">ed(1)</a> to print
! 311: bytes read/written and the ? prompt to stdout, not stderr.
! 312: <li>Modified the vmstat view in <a
! 313: href="https://man.openbsd.org/systat.1">systat(1)</a> to measure
! 314: elapsed time using <a
! 315: href="https://man.openbsd.org/clock_gettime.2">clock_gettime(2)</a>.
! 316: <li>Fixed handling of escaped backslashes in <a
! 317: href="https://man.openbsd.org/vi.1">vi(1)</a> ex_range.
! 318: <li>Corrected <a href="https://man.openbsd.org/top.1">top(1)</a>
! 319: display of online CPUs which can change based on the <a
! 320: href="https://man.openbsd.org/sysctl.2">sysctl(2)</a> sysctl setting.
1.13 benno 321: <li>Added support for a personal <a
322: href="https://man.openbsd.org/units.1">units(1)</a> library by passing
323: -f multiple times.
324:
325: <li>Made <a href="https://man.openbsd.org/rc.8">rc(8)</a> reorder
326: libraries in parallel to <a
327: href="https://man.openbsd.org/netstart.8">netstart(8)</a>, as this
328: does not depend on network access.
329:
1.22 ! benno 330: <li>Made <a href="https://man.openbsd.org/rc.8">rc(8)</a> print the
! 331: name of each library before relinking as a signal to the operator that
! 332: boot has not stalled.
! 333:
1.13 benno 334: <li>Implemented periodic display in <a
335: href="https://man.openbsd.org/iostat.8">iostat(8)</a>.
336:
337: <li>Changed <a href="https://man.openbsd.org/df.1">df(1)</a> to
338: round up fractional percentages.
339:
340: <li>Added the <a
341: href="https://man.openbsd.org/audioctl.8">audioctl(8)</a> -w option to
342: display variables periodically.
343: <li>Added short options for <a
344: href="https://man.openbsd.org/timeout.1">timeout(1)</a> --foreground
345: and --preserve-status.<br>
346: Added signal as a full argument name for <a
347: href="https://man.openbsd.org/timeout.1">timeout(1)</a> -s.
348:
349: <li>Fixed .wav files generated by <a
1.22 ! benno 350: ; href="https://man.openbsd.org/aucat.1">aucat(1)</a> by using extended
1.13 benno 351: header format.
352: <li>In <a
353: href="https://man.openbsd.org/disklabel.8">disklabel(8)</a>, use the
354: size of the largest chunk of free space, not the total of all such
355: chunks, when checking for sufficient space to add a partition.
356: <li>Fixed unbounded variable expansion in <a
357: href="https://man.openbsd.org/pkg-config.1">pkg-config(1)</a>.
358: <li>Switched to use <a
359: href="https://man.openbsd.org/llvm-strip.1">llvm-strip(1)</a> on
360: architectures that use <a
361: href="https://man.openbsd.org/ld.lld.1">ld.lld(1)</a>.
362: <li>Extended <a
363: href="https://man.openbsd.org/disklabel.8">disklabel(8)</a> template
364: parsing to allow "[mount point] *" as the specification for putting
365: the maximum available free space into a partition, and extended
366: command line parsing to allow "T-" as the specification to read the
367: template from stdin.
368: <li>Fixed a number of out of bounds reads in DNS response parsing.
369:
1.1 benno 370: </ul>
371:
372: <li>Improved hardware support and driver bugfixes, including:
373: <ul>
1.13 benno 374:

705: <li>Added <a href="https://man.openbsd.org/mount_nfs.8">mount_nfs(8)</a> to
706: sparc64 ramdisks to be able to fetch sets over NFS.
1.18 kn 707: <li>Fixed ofwboot OpenFirmware <code>map</code> call to unbreak boot on some machines.
1.17 kn 708: <li>Reduced ofwboot.net size after libz update to unbreak netboot on some machines.
709: <li>Made riscv64 bootloader support boot from RAID 1C softraid volumes.
710: <li>Made <a href="https://man.openbsd.org/installboot.8">installboot(8)</a> support
711: <a href="https://man.openbsd.org/softraid.4">softraid(4)</a> on riscv64.
1.1 benno 712: </ul>
713:
714: <li>Security improvements:
715: <ul>
1.13 benno 716: <li>Add Synthetic Memory Protections. These provide
717: <ul>
718: <li>Immutable memory mappings whose permissions and size cannot be
719: changed anymore. A new system call <a
720: href="https://man.openbsd.org/mimmutable.2">mimmutable(2)</a> enables
721: this feature.
722: <li>Execute-Only permission on memory mappings. This uses hardware
723: support where possible and emulation where the hardware does not have
1.16 jsg 724: separate execute only features.
1.13 benno 725: <li>Stack permission on mappings: On every system call the stack
726: pointer is checked. It must point to a mapping that has MAP_STACK
727: permissions.
728: <li>Pinning of syscall entry to a unique specific memory regions from
729: which system calls can be made.
730: </ul><br>
731: The execute-only mappings are active on arm64, risc-v, hppa,
732: aarch64, mips64, sparc64, amd64, mips, and power-pc platforms.
733: <!-- XXX xonly checks on copyin(9) are not described yet -->
734:
735: <li>Implemented a --executable-only option in <a href="https://man.openbsd.org/ld.bfd.1">ld.bfd(1)</a>.
736:
1.22 ! benno 737: <li>Changed <a href="https://man.openbsd.org/ld.so.1">ld.so(1)</a>
! 738: to map certain regions of memory as immutable when loading shared
! 739: libraries.
! 740:
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.
746: <li>Added retguard to amd64 syscalls.
747:
748: <li>Randomly relink and install <a
749: href="https://man.openbsd.org/sshd.8">sshd(8)</a> on boot, resulting
750: in a sshd with unknown address layout after every reboot.
751:
752: <li>Add another mitigation against classic BROP on systems without
753: execute-only mmu hardware-enforcement. A range-checking wrapper in
754: front of copyin() and copyinstr() ensures the userland source address
755: doesn't overlap the main program text and other text segments, thereby
756: making this address ranges unreadable to the kernel. No programs have
757: been discovered which require reading their own text segments with a
758: system call.
1.22 ! benno 759:
! 760: <li>On arm64, introduce mitigation of the Spectre-BHB (Branch
! 761: History Injection) CPU vulnerability by using core-specific trampoline
! 762: vectors.
! 763:
! 764: <li>Tightened the <a
! 765: href="https://man.openbsd.org/pledge.2">pledge(2)</a> after <a
! 766: href="https://man.openbsd.org/ssh.1">ssh(1)</a> session establishment.
! 767:
! 768: <li>Enabled the Data Independent Timing (DIT) feature in both the kernel and
! 769: userland on arm64 CPUs that support it to mitigate timing side-channel
! 770: attacks.
! 771:
1.1 benno 772: </ul>
773:
774: <li>Changes in the network stack:
775: <ul>
1.13 benno 776:
1.22 ! benno 777: <li>Made /dev/pf a clonable device to better track kernel ressources
! 778: used by processes.
! 779: <li>Modified TCP receive buffer size auto-scaling to use the smoothed
! 780: RTT (SRTT) instead of the timestamp option, which improves performance
! 781: on high latency networks if the timestamp option isn't available.
! 782: <li>Relaxed the requirement for multicast suppport of interfaces for
! 783: configuring IPv6. This allows non-multicast interfaces such as
! 784: point-to-point interfaces and the NBMA / point-to-multipoint
! 785: interfaces like mpe(4), mgre(4) and wg(4) to work with IPv6.
! 786:
! 787: <li>Use the new <a
! 788: href="https://man.openbsd.org/getnsecruntime.9">getnsecruntime(9)</a>
! 789: timer to check the TCP_KEEPALIVE timer only against the system
! 790: runtime, not the uptime. Prevents TCP connections to fail after
! 791: wakeing up from suspend.
! 792:
! 793:
1.13 benno 794: <li>Used stoeplitz (symmetric Toeplitz hash algorithm) to generate a
795: hash/flowid for <a href="https://man.openbsd.org/pf.4">pf(4)</a> state
796: keys. With this change, pf will hash traffic the same way that
797: hardware using a stoeplitz key will hash incoming traffic on rings.
798: stoeplitz is also used by the tcp stack to generate a flow id, which
799: is used to pick which transmit ring is used on nics with multiple
800: queues too. using the same algorithm throughout the stack encourages
801: affinity of packets to rings and softnet threads the whole way
802: through.
803:
804: <li>Prevented possible kernel crashes by dropping TCP packets with
805: destination port 0 in <a href="https://man.openbsd.org/pf.4">pf(4)</a>
806: and the stack.
807:
808: <li>Fixed a endian swap bug causing problems with <a
809: href="https://man.openbsd.org/vlan.4">vlans(4)</a> on <a
810: href="https://man.openbsd.org/em.4">em(4)</a> sparc64 systems.
811: <li>Denied "pipex no" tunnel setting for <a
812: href="https://man.openbsd.org/pppx.4">pppx(4)</a> interfaces.
1.22 ! benno 813: <li>Fixed <a href="https://man.openbsd.org/pfsync.4">pfsync(4)</a>
! 814: crashing on pf_state_key removal.
1.13 benno 815: <li>Fixed a panic in <a
816: href="https://man.openbsd.org/pfsync.4">pfsync(4)</a> when there are
817: no data ready for bulk transfer.
818: <li>Turned off TCP Segmentation Offload (TSO) if interface is added
819: to layer 2 devices.
820: <li>Improved <a href="https://man.openbsd.org/vnet.4">vnet(4)</a>
821: to work better in busy conditions.
822: <li>Added a <a href="https://man.openbsd.org/bpf.4">bpf(4)</a> timeout
823: (BIOCSWTIMEOUT) between capturing a packet and making the buffer
824: readable, preventing for example <a
825: href="https://man.openbsd.org/pflogd.8">pflogd(8)</a> waking every
826: half second even if there is nothing to read. By default this buffer
827: is infinite and must be filled to become readable.
828: <li>Avoided enabling TSO on interfaces which are already attached to a bridge.
829:
830: </ul>
1.1 benno 831:
832: <li>Routing daemons and other userland network improvements:
833: <ul>
834: <li>IPsec support was improved:
835: <ul>
1.13 benno 836: <li>Added <a href="https://man.openbsd.org/iked.8">iked(8)</a>
837: support for configuring multiple name servers.
838: <li>Synced proc.c from <a
839: href="https://man.openbsd.org/vmd.8">vmd(8)</a> to <a
840: href="https://man.openbsd.org/iked.8">iked(8)</a> to enabled fork +
841: exec for all processes. This gives each process a fresh and unique
842: address space to further improve randomization of ASLR and stack
843: protector.
844: </ul>
845:
846: <li>In <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>, <a
847: href="https://man.openbsd.org/bgpctl.8">bgpctl(8)</a> and <a
848: href="https://man.openbsd.org/bgplgd.8">bgplgd(8)</a>:
849: <ul>
850: <li>Improved performance by optimising the output filters
1.16 jsg 851: <li>Add Autonomous System Provider Authorization (ASPA) validation
1.13 benno 852: based on draft-ietf-sidrops-aspa-verification-12
853: <li>Introduce avs (ASPA validation state) filter and bgpctl
854: filter argument
855: <li>Add ASPA support for the RTR protocol based on
856: draft-ietf-sidrops-8210bis-10
857: <li>Improve open policy (RFC 9234) support and enable the capability
858: automatically if a role is specified for the peer
859: <li>Introduce a per neighbor 'role' configuration option to specify
860: the session role used by ASPA verification and the open policy
861: capability. The 'announce policy' statement was simplified at
862: the same time.
863: <li>Improve startup behaviour by introducing a small delay before
864: opening the connection to a new peer
865: <li>Support for aspa-set table config which can be provided by
866: <a
867: href="https://man.openbsd.org/rpki-client.8">rpki-client(8)</a>
868: <li>Make it possible to filter the RIB by invalid and leaked prefixes
869: in bgpctl and bgplgd
870: <li>Add OpenMetrics output to bgpctl for various BGP statistics and
871: add /metrics endpoint to bgplgd
872: <li>Fix of incorrect length checks that allowed an out-of-bounds
873: read in bgpd.
1.1 benno 874: </ul>
875: <li><a href="https://man.openbsd.org/rpki-client.8">rpki-client(8)</a> saw some changes:
876: <ul>
1.13 benno 877: <li>Add a new '-H' command line option to create a shortlist of
878: repositories to synchronize to. For example, when invoking
879: "rpki-client -H rpki.ripe.net -H chloe.sobornost.net", the utility
880: will not connect to any other hosts other than the two specified
881: through the -H option.
882: <li>Add support for validating Geofeed (RFC 9092) authenticators. To
883: see an example download https://sobornost.net/geofeed.csv and run
884: "rpki-client -f geofeed.csv"
885: <li>Add support for validating Trust Anchor Key (TAK) objects. TAK
886: objects can be used to produce new Trust Anchor Locators (TALs) signed
887: by and verified against the previous Trust Anchor. See
888: draft-ietf-sidrops-signed-tal for the full specification.
889: <li>Log lines related to RRDP/HTTPS connection problems now include the
890: IP address of the problematic endpoint (in brackets).
891: <li>Improve the error message when an invalid filename is encountered
892: in the rpkiManifest field in the Subject Access Information (SIA)
893: extension.
894: <li>Emit a warning when unexpected X.509 extensions are encountered.
895: <li>Restrict the ROA ipAddrBlocks field to only allow two
896: ROAIPAddressFamily structures (one per address family). See
897: draft-ietf-sidrops-rfc6482bis.
898: <li>Check the absence of the Path Length constraint in the Basic
899: Constraints extension.
900: <li>Restrict the SIA extension to only allow the signedObject and
901: rpkiNotify accessMethods.
902: <li>Check that the Signed Object access method is present in ROA, MFT,
903: ASPA, TAK, and GBR End-Entity certificates.
904: <li>In addition to the 'rsync://' scheme, also permit other schemes
905: (such as 'https://') in the SIA signedObject access method.
906: <li>Check that the KeyUsage extension is set to nothing but
907: digitalSignature on End-Entity certificates.
1.16 jsg 908: <li>Check that the KeyUsage extension is set to nothing but keyCertSign
1.13 benno 909: and CRLSign on CA certificates.
910: <li>Check that the ExtendedKeyUsage extension is absent on CA
911: certificates.
912: <li>Fix a bug in the handling of the port of http_proxy.
913: <li>The '-r' command line option has been deprecated.
914: <li>Filemode (-f) output is now presented as a text based table.
915: <li>The 'expires' key in the JSON/CSV/OpenBGPD output formats is now
916: calculated with more accuracy. The calculation takes into account the
917: nextUpdate value of all intermediate CRLs in the signature path
918: towards the trust anchor, in addition to the expiry moment of the
919: leaf-CRL and CAs.
920: <li>Handling of CRLs and Manifests in the face of inconsistent RRDP delta
921: publications has been improved. A copy of an alternative version of
922: the applicable CRL is kept in the staging area of the cache directory,
923: in order to increase the potential for establishing a complete
924: publication point, in cases where a single publication point update
925: was smeared across multiple RRDP delta files.
926: <li>The OpenBGPD configuration output now includes validated Autonomous
927: System Provider Authorization (ASPA) payloads as an 'aspa-set {}'
928: configuration block.
929: <li>When rpki-client is invoked with increased verbosity ('-v'), the
930: current RRDP Serial & Session ID are shown to aid debugging.
931: <li>Self-signed X.509 certificates (such as Trust Anchor certificates)
932: now are considered invalid if they contain an X.509
933: AuthorityInfoAccess extension.
934: <li>Signed Objects where the CMS signing-time attribute contains a
935: timestamp later then the X.509 certificate's notAfter timestamp are
936: considered invalid.
937: <li>Manifests where the CMS signing-time attribute contains a timestamp
938: later then the Manifest eContent nextUpdate timestamp are considered
939: invalid.
940: <li>Any objects whose CRL Distribution Points extension contains a
941: CRLIssuer, CRL Reasons, or nameRelativeToCRLIssuer field are
942: considered invalid in accordance with RFC 6487 section 4.8.6.
943: <li>For every X.509 certificate the SHA-1 of the Subject Public Key is
944: calculated and compared to the Subject Key Identifier (SKI), if a
945: mismatch is found the certificate is not trusted.
946: <li>Require the outside-TBS signature OID for every X.509 intermediate
947: CA certificate and CRL to be sha256WithRSAEncryption.
948: <li>Require the RSA key pair modulus and public exponent parameters to
949: strictly conform to the RFC 7935 profile.
950: <li>Ensure there is no trailing garbage present in Signed Objects beyond
951: the self-embedded length field.
952: <li>Require RRDP Session IDs to strictly be version 4 UUIDs.
953: <li>When decoding and validating an individual RPKI file using filemode
954: (rpki-client -f file), display the signature path towards the trust
955: anchor, and the timestamp when the signature path will expire.
956: <li>When decoding and validating an individual RPKI file using filemode
957: (rpki-client -f file), display the optional CMS signing-time, and
958: non-optional X.509 notBefore, and X.509 notAfter timestamps.

1.1 benno 1185: </ul>
1186: </ul>
1187:
1.14 benno 1188: <li>OpenSSH 9.3 and OpenSSH 9.2<br>
1189: This release of OpenBSD includes the changes made to OpenSSH since release 9.1:
1.1 benno 1190: <ul>
1191: <li>Security
1192: <ul>
1.14 benno 1193: <li>ssh-add(1): when adding smartcard keys to ssh-agent(1) with the
1194: per-hop destination constraints (ssh-add -h ...) added in OpenSSH
1195: 8.9, a logic error prevented the constraints from being
1196: communicated to the agent. This resulted in the keys being added
1197: without constraints. The common cases of non-smartcard keys and
1198: keys without destination constraints are unaffected. This problem
1199: was reported by Luci Stanescu.
1200: <li>ssh(1): Portable OpenSSH provides an implementation of the
1201: getrrsetbyname(3) function if the standard library does not
1202: provide it, for use by the VerifyHostKeyDNS feature. A
1203: specifically crafted DNS response could cause this function to
1204: perform an out-of-bounds read of adjacent stack data, but this
1205: condition does not appear to be exploitable beyond denial-of-
1206: service to the ssh(1) client.<br>
1207: The getrrsetbyname(3) replacement is only included if the system's
1208: standard library lacks this function and portable OpenSSH was not
1209: compiled with the ldns library (--with-ldns). getrrsetbyname(3) is
1210: only invoked if using VerifyHostKeyDNS to fetch SSHFP records. This
1211: problem was found by the Coverity static analyzer.
1212: <li>sshd(8): fix a pre-authentication double-free memory fault
1213: introduced in OpenSSH 9.1. This is not believed to be exploitable,
1214: and it occurs in the unprivileged pre-auth process that is
1215: subject to chroot(2) and is further sandboxed on most major
1216: platforms.
1217: <li>ssh(8): in OpenSSH releases after 8.7, the PermitRemoteOpen option
1218: would ignore its first argument unless it was one of the special
1219: keywords "any" or "none", causing the permission list to fail open
1220: if only one permission was specified. bz3515
1221: <li>ssh(1): if the CanonicalizeHostname and CanonicalizePermittedCNAMEs
1222: options were enabled, and the system/libc resolver did not check
1223: that names in DNS responses were valid, then use of these options
1224: could allow an attacker with control of DNS to include invalid
1225: characters (possibly including wildcards) in names added to
1226: known_hosts files when they were updated. These names would still
1227: have to match the CanonicalizePermittedCNAMEs allow-list, so
1228: practical exploitation appears unlikely.
1229: </ul>
1.1 benno 1230: <li>Potentially-incompatible changes
1.14 benno 1231: <ul>
1232: <li>ssh(1): add a new EnableEscapeCommandline ssh_config(5) option that
1233: controls whether the client-side ~C escape sequence that provides a
1234: command-line is available. Among other things, the ~C command-line
1235: could be used to add additional port-forwards at runtime.<br>
1236: This option defaults to "no", disabling the ~C command-line that
1237: was previously enabled by default. Turning off the command-line
1238: allows platforms that support sandboxing of the ssh(1) client
1239: (currently only OpenBSD) to use a stricter default sandbox policy.
1240: </ul>
1241: <li>New features
1242: <ul>
1243: <li>ssh-keygen(1), ssh-keyscan(1): accept -Ohashalg=sha1|sha256 when
1244: outputting SSHFP fingerprints to allow algorithm selection. bz3493
1245: <li>sshd(8): add a `sshd -G` option that parses and prints the
1246: effective configuration without attempting to load private keys
1247: and perform other checks. This allows usage of the option before
1248: keys have been generated and for configuration evaluation and
1249: verification by unprivileged users.
1250: <li>sshd(8): add support for channel inactivity timeouts via a new
1251: sshd_config(5) ChannelTimeout directive. This allows channels that
1252: have not seen traffic in a configurable interval to be
1253: automatically closed. Different timeouts may be applied to session,
1254: X11, agent and TCP forwarding channels.
1255: <li>sshd(8): add a sshd_config UnusedConnectionTimeout option to
1256: terminate client connections that have no open channels for a
1257: length of time. This complements the ChannelTimeout option above.
1258: <li>sshd(8): add a -V (version) option to sshd like the ssh client has.
1259: <li>ssh(1): add a "Host" line to the output of ssh -G showing the
1260: original hostname argument. bz3343
1261: <li>scp(1), sftp(1): add a -X option to both scp(1) and sftp(1) to
1262: allow control over some SFTP protocol parameters: the copy buffer
1263: length and the number of in-flight requests, both of which are used
1264: during upload/download. Previously these could be controlled in
1265: sftp(1) only. This makes them available in both SFTP protocol
1266: clients using the same option character sequence.
1267: <li>ssh-keyscan(1): allow scanning of complete CIDR address ranges,
1268: e.g. "ssh-keyscan 192.168.0.0/24". If a CIDR range is passed, then
1269: it will be expanded to all possible addresses in the range
1270: including the all-0s and all-1s addresses. bz#976
1271: <li>ssh(1): support dynamic remote port forwarding in escape
1272: command-line's -R processing. bz#3499
1273: </ul>
1.1 benno 1274: <li>Bugfixes
1.14 benno 1275: <ul>
1276: <li>scp(1), sftp(1): fix progressmeter corruption on wide displays;
1277: bz3534
1278: <li>ssh-add(1), ssh-keygen(1): use RSA/SHA256 when testing usability
1279: of private keys as some systems are starting to disable RSA/SHA1
1280: in libcrypto.
1281: <li>sftp-server(8): fix a memory leak. GHPR363
1.16 jsg 1282: <li>ssh(1), sshd(8), ssh-keyscan(1): remove vestigial protocol
1.14 benno 1283: compatibility code and simplify what's left.
1284: <li>Fix a number of low-impact Coverity static analysis findings.
1285: These include several reported via bz2687
1286: <li>ssh_config(5), sshd_config(5): mention that some options are not
1287: first-match-wins.
1288: <li>Rework logging for the regression tests. Regression tests will now
1289: capture separate logs for each ssh and sshd invocation in a test.
1290: <li>ssh(1): make `ssh -Q CASignatureAlgorithms` work as the manpage
1291: says it should; bz3532.
1292: <li>ssh(1): ensure that there is a terminating newline when adding a
1293: new entry to known_hosts; bz3529
1294: <li>ssh(1): when restoring non-blocking mode to stdio fds, restore
1295: exactly the flags that ssh started with and don't just clobber them
1296: with zero, as this could also remove the append flag from the set.
1297: bz3523
1298: <li>ssh(1): avoid printf("%s", NULL) if using UserKnownHostsFile=none
1299: and a hostkey in one of the system known hosts file changes.
1300: <li>scp(1): switch scp from using pipes to a socket-pair for
1301: communication with its ssh sub-processes, matching how sftp(1)
1302: operates.
1303: <li>sshd(8): clear signal mask early in main(); sshd may have been
1304: started with one or more signals masked (sigprocmask(2) is not
1305: cleared on fork/exec) and this could interfere with various things,
1306: e.g. the login grace timer. Execution environments that fail to
1307: clear the signal mask before running sshd are clearly broken, but
1308: apparently they do exist.
1309: <li>ssh(1): warn if no host keys for hostbased auth can be loaded.
1310: <li>sshd(8): Add server debugging for hostbased auth that is queued and
1311: sent to the client after successful authentication, but also logged
1312: to assist in diagnosis of HostbasedAuthentication problems. bz3507
1313: <li>ssh(1): document use of the IdentityFile option as being usable to
1314: list public keys as well as private keys. GHPR352
1315: <li>sshd(8): check for and disallow MaxStartups values less than or
1316: equal to zero during config parsing, rather than failing later at
1317: runtime. bz3489
1318: <li>ssh-keygen(1): fix parsing of hex cert expiry times specified on
1319: the command-line when acting as a CA.
1320: <li>scp(1): when scp(1) is using the SFTP protocol for transport (the
1321: default), better match scp/rcp's handling of globs that don't match
1322: the globbed characters but do match literally (e.g. trying to
1323: transfer a file named "foo.[1]"). Previously scp(1) in SFTP mode
1324: would not match these pathnames but legacy scp/rcp mode would.
1325: bz3488
1326: <li>ssh-agent(1): document the "-O no-restrict-websafe" command-line
1327: option.
1328: <li>ssh(1): honour user's umask(2) if it is more restrictive then the
1329: ssh default (022).

1626: <section id=sourcecode>
1627: <h3>Notes about the source code</h3>
1628: <p>
1629: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1630: This file contains everything you need except for the kernel sources,
1631: which are in a separate archive.
1632: To extract:
1633: <blockquote><pre>
1634: # <kbd>mkdir -p /usr/src</kbd>
1635: # <kbd>cd /usr/src</kbd>
1636: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1637: </pre></blockquote>
1638: <p>
1639: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1640: This file contains all the kernel sources you need to rebuild kernels.
1641: To extract:
1642: <blockquote><pre>
1643: # <kbd>mkdir -p /usr/src/sys</kbd>
1644: # <kbd>cd /usr/src</kbd>
1645: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1646: </pre></blockquote>
1647: <p>
1648: Both of these trees are a regular CVS checkout. Using these trees it
1649: is possible to get a head-start on using the anoncvs servers as
1650: described <a href="anoncvs.html">here</a>.
1651: Using these files
1652: results in a much faster initial CVS update than you could expect from
1653: a fresh checkout of the full OpenBSD source tree.

1659: <h3>Ports Tree</h3>
1660: <p>
1661: A ports tree archive is also provided. To extract:
1662: <blockquote><pre>
1663: # <kbd>cd /usr</kbd>
1664: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1665: </pre></blockquote>
1666: <p>
1667: Go read the <a href="faq/ports/index.html">ports</a> page
1668: if you know nothing about ports
1669: at this point. This text is not a manual of how to use ports.
1670: Rather, it is a set of notes meant to kickstart the user on the
1671: OpenBSD ports system.
1672: <p>
1673: The <i>ports/</i> directory represents a CVS checkout of our ports.
1674: As with our complete source tree, our ports tree is available via
1675: <a href="anoncvs.html">AnonCVS</a>.
1676: So, in order to keep up to date with the -stable branch, you must make
1677: the <i>ports/</i> tree available on a read-write medium and update the tree
1678: with a command like:
1679: <blockquote><pre>
1680: # <kbd>cd /usr/ports</kbd>
1681: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_3</kbd>
1682: </pre></blockquote>
1683: <p>
1684: [Of course, you must replace the server name here with a nearby anoncvs
1685: server.]
1686: <p>
1687: Note that most ports are available as packages on our mirrors. Updated
1688: ports for the 7.3 release will be made available if problems arise.
1689: <p>
1690: If you're interested in seeing a port added, would like to help out, or just
1691: would like to know more, the mailing list
1692: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
