72: <h3>What's New</h3>
73: <p>
74: This is a partial list of new features and systems included in OpenBSD 7.3.
75: For a comprehensive list, see the <a href="plus73.html">changelog</a> leading
76: to 7.3.
77:
78: <ul>
79:
80: <li>Various kernel improvements:
81: <ul>
1.41 benno 82:
83:
1.30 jsg 84: <li>Added <a href="https://man.openbsd.org/waitid.2">waitid(2)</a>,
85: wait for process state change.
86: <li>Added <a href="https://man.openbsd.org/pinsyscall.2">pinsyscall(2)</a>,
87: specify the call stub for a specific system call.
88: <li>Added <a href="https://man.openbsd.org/getthrname.2">getthrname(2)</a> and
89: <a href="https://man.openbsd.org/setthrname.2">setthrname(2)</a>,
90: get or set thread name.
1.41 benno 91: <li>Added WTRAPPED option for <a
92: href="https://man.openbsd.org/waitid.2">waitid(2)</a> to control
93: whether CLD_TRAPPED state changes, i.e., ptrace(2) on a process, are reported.
94:
95: <!-- kernel internals -->
1.22 benno 96: <li>Introduced <a
97: href="https://man.openbsd.org/clockintr.9">clockintr(9)</a>, a
1.31 jsg 98: machine-independent clock interrupt scheduler. Switched all
1.51 cheloha 99: architectures to use the new subsystem.
1.22 benno 100: <li>Introduced a new kern.autoconf_serial <a
101: href="https://man.openbsd.org/sysctl.8">sysctl(8)</a> that can be used
102: by userland to monitor state changes of the kernel device tree.
103: <li>Fixed <a href="https://man.openbsd.org/pmap.9">pmap(9)</a> bugs
104: involving entering an executable mapping for a page before
105: synchronizing the data and instruction cache on arm64 and riscv64.
1.51 cheloha 106: <li>Removed copystr(9) from the public API.
107: <li>Added <a
108: href="https://man.openbsd.org/getnsecruntime.9">getnsecruntime(9)</a>.
109: Offers fast access to the system runtime clock at the cost of precision.
1.41 benno 110:
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>.
1.41 benno 113:
1.24 jsg 114: <li>On arm64, avoid using 1GB mappings for the identity map in the
1.21 benno 115: early kernel bootstrap phase and when booting the secondary CPUs. This
116: avoids accidentally mapping memory regions that should not be mapped
117: (i.e. secure memory) as all mapped memory can be accessed
118: speculatively.
1.22 benno 119: <li>On arm64, add a machdep.lidaction <a
120: href="https://man.openbsd.org/sysctl.8">sysctl(8)</a> for <a
121: href="https://man.openbsd.org/aplsmc.4">aplsmc(4)</a> Apple Silicon
122: laptops.<br>
123: The arm64 default for the machdep.lidaction is 1, making the
1.13 benno 124: system suspend when the lid is closed. <a
125: href="https://man.openbsd.org/aplsmc.4">aplsmc(4)</a> provides support
126: for the lid position sensor.
127: <li>Changed arm64 suspend idle loop from WFE to WFI, avoiding spurious
128: wakeups while other CPUs are still active.
1.41 benno 129: <li>Added new <a href="https://man.openbsd.org/dt.4">dt(4)</a> tracing ioctl
1.13 benno 130: DTIOCARGS to get the type of probe arguments.
1.1 benno 131: </ul>

138: <li>Unlocked <a href="https://man.openbsd.org/sched_yield.2">sched_yield(2)</a>.
1.51 cheloha 139: <li>Added support for per-CPU counters to
140: <a href="https://man.openbsd.org/evcount.9">evcount(9)</a>.
141: Useful for counting events that are prone to occur simultaneously
142: across multiple CPUs, like clock interrupts and IPIs.
1.22 benno 143: <li>Moved <a href="https://man.openbsd.org/pf.4">pf(4)</a> purge
144: tasks out from under the kernel lock.
145: <li>Unlocked <a href="https://man.openbsd.org/ioctl.2">ioctl(2)</a>
146: SIOCGIFCONF, SIOCGIFGMEMB, SIOCGIFGATTR, and SIOCGIFGLIST.
147: <li>Protected interface tables in <a
148: href="https://man.openbsd.org/pf.4">pf(4)</a> with PF_LOCK(), allowing
149: removal of NET_LOCK() protection from the <a
150: href="https://man.openbsd.org/ioctl.2">ioctl(2)</a> code path in pf.
151: <li>Unlocked <a
152: href="https://man.openbsd.org/getsockopt.2">getsockopt(2)</a> and <a
153: href="https://man.openbsd.org/setsockopt.2">setsockopt(2)</a>.
154: <li>Completed removing kernel lock from IPv6 read ioctls.

185: href="https://man.openbsd.org/inteldrm.4">inteldrm(4)</a>, making <a
186: href="https://man.openbsd.org/xbacklight.1">xbacklight(1)</a> work
187: when using the Xorg modesetting driver.
1.1 benno 188: </ul>
189:
190: <li>VMM/VMD improvements
191: <ul>
1.22 benno 192: <li>Updated <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> to
1.51 cheloha 193: permit SVM guests read access to MSR_HWCR and MSR_PSTATEDEF.
194: Guests can use these registers on AMD 17h and 19h hosts to
195: determine the TSC frequency without calibrating against a
196: second clock.
1.22 benno 197: <li>Allocated reference for vm and vcpu SLISTs in <a
198: href="https://man.openbsd.org/vmm.4">vmm(4)</a>, keeping vmm from
199: triggering excessive wakeup calls while iterating through the list of
200: vms while servicing an <a
201: href="https://man.openbsd.org/ioctl.2">ioctl(2)</a>.
202: <li>Set <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> RAX guest
203: register state based on VMCB.
204: <li>Removed locking in <a
205: href="https://man.openbsd.org/vmm.4">vmm(4)</a> vmm_intr_pending,
206: reducing slowdowns due to requests for a lock held while the VM is
207: running.
208: <li>Increased speed of delivery of interrupts to a running vcpu in <a
209: href="https://man.openbsd.org/vmm.4">vmm(4)</a>.
210: <li>Made <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> treat vcpu
211: lists as immutable, removing the need to reference count individual
212: vcpu objects and use a rwlock.
1.13 benno 213: <li>Implemented zero-copy operations on virtqueues in <a
214: href="https://man.openbsd.org/vmd.8">vmd(8)</a>.
215: <li>Provided a detailed e820 memory map when booting <a
216: href="https://man.openbsd.org/vmd.8">vmd(8)</a> guests with SeaBIOS.
217: When a vm initializes memory ranges, we now track what each range
218: represents. This information can be used to supply the e820 memory map
219: to SeaBIOS via the fw_cfg interface allowing it to properly
220: communicate memory ranges to a guest operating system. With this
221: special cases in ports can be removed.
222: <li>Added thread names to vm processes in <a
223: href="https://man.openbsd.org/vmd.8">vmd(8)</a>, visible in <a
224: href="https://man.openbsd.org/ps.1">ps(1)</a>.
225: <li>Hid the WAITPKG cpu feature from <a
226: href="https://man.openbsd.org/vmm.4">vmm(4)</a> guests, preventing
227: invalid instruction exceptions. Also added WAITPKG feature
228: identification to i386 and amd64.
229: <li>Changed <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> to
230: only open /dev/vmm once, having the parent process send the fd to the
231: vmm child process.
1.35 benno 232: <li>Restricted <a href="https://man.openbsd.org/vmm.4">vmm(4)</a>
233: exposed cpuid extended feature flags.
234: <li>Adjusted <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> error
235: paths to avoid removal of configuration-defined (known) VMs on error.
1.13 benno 236: <li>Stopped being paranoid about hypervisor correct PKU handling.<br>
237: Added saving and restoring guest PKRU to <a
238: href="https://man.openbsd.org/vmm.4">vmm(4)</a>. Expose the PKU cpuid
239: bit to the guest if in use on the host.
1.35 benno 240: <li>Made <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> scan the
241: PCI bus to determine bootorder strings.
1.1 benno 242: </ul>

251: href="https://man.openbsd.org/munmap.2">munmap(2)</a> reporting to <a
252: href="https://man.openbsd.org/kdump.1">kdump(1)</a>.
1.13 benno 253: <li>Added <a
254: href="https://man.openbsd.org/lastcomm.1">lastcomm(1)</a> reporting
255: for process kills due to <a
256: href="https://man.openbsd.org/execve.2">execve(2)</a> from non-pinned
1.46 namn 257: syscall address.
1.1 benno 258: </ul>
259:
260: <li>Various bugfixes and tweaks in userland:
261: <ul>
1.26 jsg 262: <li>Allow TZ to contain absolute paths starting with /usr/share/zoneinfo.

303: href="https://man.openbsd.org/llvm-strip.1">llvm-strip(1)</a> on
304: architectures that use <a
1.43 krw 305: href="https://man.openbsd.org/ld.lld.1">ld.lld(1)</a>.
1.37 benno 306: <!-- rc scripts -->
1.13 benno 307: <li>Made <a href="https://man.openbsd.org/rc.8">rc(8)</a> reorder
308: libraries in parallel to <a
309: href="https://man.openbsd.org/netstart.8">netstart(8)</a>, as this
310: does not depend on network access.
1.22 benno 311: <li>Made <a href="https://man.openbsd.org/rc.8">rc(8)</a> print the
312: name of each library before relinking as a signal to the operator that

1.35 benno 335: command line parsing to allow "T-" as the specification to read the
336: template from stdin.
1.44 krw 337: <li>Repaired <a
338: href="https://man.openbsd.org/disklabel.8">disklabel(8)</a>
339: to check for D_VENDOR flag in d_flags, not d_secpercyl.
1.55 jsg 340: <li>Removed remnants of DEC standard 144 bad sector code from

705: <li>Made <a href="https://man.openbsd.org/installboot.8">installboot(8)</a> silently skip
1.46 namn 706: <a href="https://man.openbsd.org/softraid.4">softraid(4)</a> keydisks.
1.17 kn 707: <li>Fixed passing explicit stages files to
708: <a href="https://man.openbsd.org/installboot.8">installboot(8)</a>.
1.38 benno 709: <!-- architecture specific -->
1.22 benno 710: <li>Added <a
711: href="https://man.openbsd.org/mount_nfs.8">mount_nfs(8)</a> to the
712: sparc64 installer, to fetch sets over NFS.
713: <li>Copy the apple-boot firmware to EFI system partition, enabling
714: automatic bootloader updates on Apple Silicon computers.
1.18 kn 715: <li>Made the installer stop printing MD post installation instructions on upgrades.
716: <li>Made it possible to set keyboard layout(s) in arm64's installer.
717: <li>Added initial support in the installer for guided disk
718: encryption for amd64, i386, riscv64 and sparc64.
1.22 benno 719: <li>Added passing of boot device information from the bootloader to
720: the kernel on luna88k.
1.13 benno 721: <li>Switched luna88k boot loader to MI boot code.
1.18 kn 722: <li>Made the luna88k bootloader display a puffy boot logo.
1.13 benno 723: <li>Made <a href="https://man.openbsd.org/ls.1">ls(1)</a> work
724: correctly in the luna88k bootloader.
725: <li>Made <a href="https://man.openbsd.org/time.1">time(1)</a> work
726: correctly in the luna88k bootloader.
727: <li>Removed dangerous user-settable "addr" variable from MI
728: bootloader, only compiling tty-related code on platforms where it
729: makes sense for the bootloader to control it.
730: <li>Added "machine poweroff" command on luna88k bootloader.
731: <li>Switched alpha to machine-independent boot blocks.
1.46 namn 732: <li>Switched all architectures' ramdisks (except alpha's and luna88k's) to use
1.17 kn 733: <a href="https://man.openbsd.org/installboot.8">installboot(8)</a> <code>-p</code>.
1.18 kn 734: <li>Fixed ofwboot OpenFirmware <code>map</code> call to unbreak boot on some machines.
1.17 kn 735: <li>Reduced ofwboot.net size after libz update to unbreak netboot on some machines.
736: <li>Made riscv64 bootloader support boot from RAID 1C softraid volumes.
737: <li>Made <a href="https://man.openbsd.org/installboot.8">installboot(8)</a> support
738: <a href="https://man.openbsd.org/softraid.4">softraid(4)</a> on riscv64.
1.55 jsg 739: <li>Stopped creating defunct vax (ra, rx), hp300 (hd) and sparc (xy, xd)
1.45 krw 740: devices in /dev.
1.1 benno 741: </ul>
742:
743: <li>Security improvements:
744: <ul>
1.46 namn 745: <li>Permissions (RWX, MAP_STACK, etc.) on address space regions can
1.23 benno 746: be made <a href="https://man.openbsd.org/mimmutable.2">immutable</a>,
747: so that <a href="https://man.openbsd.org/mmap.2">mmap(2)</a>, <a
748: href="https://man.openbsd.org/mprotect.2">mprotect(2)</a> or <a
749: href="https://man.openbsd.org/munmap.2">munmap(2)</a> fail with EPERM.
750: Most of the program static address space is now automatically
751: immutable (main program, ld.so, main stack, load-time shared
752: libraries, and dlopen()'d libraries mapped without RTLD_NODELETE).
753: Programmers can request non-immutable static data using the
754: "openbsd.mutable" section, or manually bring immutability to (page
755: aligned heap objects) using <a
756: href="https://man.openbsd.org/mimmutable.2">mimmutable(2)</a>.
1.47 otto 757: The main internal data of <a
758: href="https://man.openbsd.org/malloc.3">malloc(3)</a>
759: is marked immutable.
1.23 benno 760: <li>Some architectures now have non-readable code ("xonly"), both from
761: the perspective of userland reading its own memory, or the kernel
762: trying to read memory in a system call. Many sloppy practices in
1.50 deraadt 763: userland code had to be repaired to allow this. The linker
764: (<a href="https://man.openbsd.org/ld.lld.1">ld.lld(1)</a> or
765: <a href="https://man.openbsd.org/ld.bfd.1">ld.bfd(1)</a>) option
1.23 benno 766: --execute-only is enabled by default. In order of development: arm64,
1.46 namn 767: riscv64, hppa, amd64, powerpc64, powerpc (G5 only), octeon, and sparc64
768: (sun4u only; unfinished).
769: <li>These can still benefit from switching to --execute-only binaries if the
1.23 benno 770: cpu generates different traps for instruction-fetch versus data-fetch.
771: The VM system will not allow memory to be read before it was executed
772: which is valuable together with library relinking. Architectures
773: switched over include loongson.
774: <li><a href="https://man.openbsd.org/ld.so.1">ld.so(1)</a> and crt0
775: register the location of the <a
776: href="https://man.openbsd.org/execve.2">execve(2)</a> stub with the
777: kernel using pinsyscall(2), after which the kernel only accepts an
778: execve call from that specific location.
1.13 benno 779: <li>Added <a href="https://man.openbsd.org/execve.2">execve(2)</a>
780: violations of <a
781: href="https://man.openbsd.org/pinsyscall.2">pinsyscall(2)</a> policy
782: to the daily mail, available by setting rc.conf.local(5)
783: accounting=YES.
1.23 benno 784: <li>Added retguard (consistency-check the return address on the
785: stack) to amd64 syscalls.
786: <li>sshd random relinking at boot: Randomly relink and install <a
787: href="https://man.openbsd.org/sshd.8">sshd(8)</a>, resulting
788: in a sshd binary with unknown address layout after every reboot.
1.13 benno 789: <li>Add another mitigation against classic BROP on systems without
790: execute-only mmu hardware-enforcement. A range-checking wrapper in
1.23 benno 791: front of <a href="https://man.openbsd.org/copyin.9">copyin(9)</a> and
1.33 tj 792: <a href="https://man.openbsd.org/copyinstr.9">copyinstr(9)</a> ensures
1.23 benno 793: the userland source address doesn't overlap the main program text and
1.46 namn 794: other text segments, thereby making these address ranges unreadable to
1.23 benno 795: the kernel. No programs have been discovered which require reading
796: their own text segments with a system call.
1.22 benno 797: <li>On arm64, introduce mitigation of the Spectre-BHB (Branch
798: History Injection) CPU vulnerability by using core-specific trampoline
799: vectors.
1.23 benno 800: <li>Enabled the arm64 Data Independent Timing (DIT) feature in both the kernel and
801: userland on CPUs that support it to mitigate timing side-channel
1.22 benno 802: attacks.
1.1 benno 803: </ul>
804:
805: <li>Changes in the network stack:
806: <ul>
1.24 jsg 807: <li>Made /dev/pf a clonable device to better track kernel resources
1.22 benno 808: used by processes.
809: <li>Modified TCP receive buffer size auto-scaling to use the smoothed
810: RTT (SRTT) instead of the timestamp option, which improves performance
811: on high latency networks if the timestamp option isn't available.
1.24 jsg 812: <li>Relaxed the requirement for multicast support of interfaces for
1.22 benno 813: configuring IPv6. This allows non-multicast interfaces such as
814: point-to-point interfaces and the NBMA / point-to-multipoint
815: interfaces like mpe(4), mgre(4) and wg(4) to work with IPv6.
1.51 cheloha 816: <li>Measure the TCP_KEEPALIVE timeout with <a
1.22 benno 817: href="https://man.openbsd.org/getnsecruntime.9">getnsecruntime(9)</a>
1.54 jsg 818: instead of the system uptime.
1.51 cheloha 819: Prevents TCP connections from needlessly failing en masse after
820: waking a system from suspend.
1.13 benno 821: <li>Used stoeplitz (symmetric Toeplitz hash algorithm) to generate a
822: hash/flowid for <a href="https://man.openbsd.org/pf.4">pf(4)</a> state
823: keys. With this change, pf will hash traffic the same way that
824: hardware using a stoeplitz key will hash incoming traffic on rings.
1.27 jsg 825: stoeplitz is also used by the TCP stack to generate a flow id, which
1.13 benno 826: is used to pick which transmit ring is used on nics with multiple
1.46 namn 827: queues, too. Using the same algorithm throughout the stack encourages
1.13 benno 828: affinity of packets to rings and softnet threads the whole way
829: through.
830: <li>Prevented possible kernel crashes by dropping TCP packets with
831: destination port 0 in <a href="https://man.openbsd.org/pf.4">pf(4)</a>
832: and the stack.
1.33 tj 833: <li>Fixed an endian swap bug causing problems with <a
1.27 jsg 834: href="https://man.openbsd.org/vlan.4">vlan(4)</a> on <a
1.13 benno 835: href="https://man.openbsd.org/em.4">em(4)</a> sparc64 systems.
836: <li>Denied "pipex no" tunnel setting for <a
837: href="https://man.openbsd.org/pppx.4">pppx(4)</a> interfaces.
1.22 benno 838: <li>Fixed <a href="https://man.openbsd.org/pfsync.4">pfsync(4)</a>
839: crashing on pf_state_key removal.
1.13 benno 840: <li>Fixed a panic in <a
1.46 namn 841: href="https://man.openbsd.org/pfsync.4">pfsync(4)</a> when there is
1.13 benno 842: no data ready for bulk transfer.
843: <li>Turned off TCP Segmentation Offload (TSO) if interface is added
844: to layer 2 devices.
845: <li>Improved <a href="https://man.openbsd.org/vnet.4">vnet(4)</a>
846: to work better in busy conditions.
847: <li>Added a <a href="https://man.openbsd.org/bpf.4">bpf(4)</a> timeout
848: (BIOCSWTIMEOUT) between capturing a packet and making the buffer
1.46 namn 849: readable, preventing, for example, <a
1.13 benno 850: href="https://man.openbsd.org/pflogd.8">pflogd(8)</a> waking every
851: half second even if there is nothing to read. By default this buffer
852: is infinite and must be filled to become readable.
853: <li>Avoided enabling TSO on interfaces which are already attached to a bridge.
854: </ul>
1.1 benno 855:
856: <li>Routing daemons and other userland network improvements:
857: <ul>
858: <li>IPsec support was improved:
859: <ul>
1.13 benno 860: <li>Added <a href="https://man.openbsd.org/iked.8">iked(8)</a>
861: support for configuring multiple name servers.
862: <li>Synced proc.c from <a
863: href="https://man.openbsd.org/vmd.8">vmd(8)</a> to <a
1.46 namn 864: href="https://man.openbsd.org/iked.8">iked(8)</a> to enable fork +
1.13 benno 865: exec for all processes. This gives each process a fresh and unique
866: address space to further improve randomization of ASLR and stack
867: protector.
868: </ul>
869: <li>In <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>, <a
870: href="https://man.openbsd.org/bgpctl.8">bgpctl(8)</a> and <a
871: href="https://man.openbsd.org/bgplgd.8">bgplgd(8)</a>:
872: <ul>
1.46 namn 873: <li>Improved performance by optimising the output filters.
1.16 jsg 874: <li>Add Autonomous System Provider Authorization (ASPA) validation
1.13 benno 875: based on draft-ietf-sidrops-aspa-verification-12
876: <li>Introduce avs (ASPA validation state) filter and bgpctl
1.46 namn 877: filter argument.
1.38 benno 878: <li>Add ASPA support for the RTR protocol based on
1.46 namn 879: draft-ietf-sidrops-8210bis-10.
1.38 benno 880: <li>Improve open policy (RFC 9234) support and enable the capability
1.46 namn 881: automatically if a role is specified for the peer.
882: <li>Introduce a per-neighbor 'role' configuration option to specify
1.13 benno 883: the session role used by ASPA verification and the open policy
884: capability. The 'announce policy' statement was simplified at
885: the same time.
1.38 benno 886: <li>Improve startup behaviour by introducing a small delay before
1.46 namn 887: opening the connection to a new peer.
1.38 benno 888: <li>Support for aspa-set table config which can be provided by
1.13 benno 889: <a
1.46 namn 890: href="https://man.openbsd.org/rpki-client.8">rpki-client(8)</a>.
1.38 benno 891: <li>Make it possible to filter the RIB by invalid and leaked prefixes
1.46 namn 892: in bgpctl and bgplgd.
1.38 benno 893: <li>Add OpenMetrics output to bgpctl for various BGP statistics and
1.46 namn 894: add /metrics endpoint to bgplgd.
1.38 benno 895: <li>Fix of incorrect length checks that allowed an out-of-bounds
1.13 benno 896: read in bgpd.
1.1 benno 897: </ul>
898: <li><a href="https://man.openbsd.org/rpki-client.8">rpki-client(8)</a> saw some changes:
899: <ul>
1.13 benno 900: <li>Add a new '-H' command line option to create a shortlist of
901: repositories to synchronize to. For example, when invoking
902: "rpki-client -H rpki.ripe.net -H chloe.sobornost.net", the utility
903: will not connect to any other hosts other than the two specified
904: through the -H option.
905: <li>Add support for validating Geofeed (RFC 9092) authenticators. To
906: see an example download https://sobornost.net/geofeed.csv and run
907: "rpki-client -f geofeed.csv"
908: <li>Add support for validating Trust Anchor Key (TAK) objects. TAK
909: objects can be used to produce new Trust Anchor Locators (TALs) signed
910: by and verified against the previous Trust Anchor. See
911: draft-ietf-sidrops-signed-tal for the full specification.
912: <li>Log lines related to RRDP/HTTPS connection problems now include the
913: IP address of the problematic endpoint (in brackets).
914: <li>Improve the error message when an invalid filename is encountered
915: in the rpkiManifest field in the Subject Access Information (SIA)
916: extension.
917: <li>Emit a warning when unexpected X.509 extensions are encountered.
918: <li>Restrict the ROA ipAddrBlocks field to only allow two
919: ROAIPAddressFamily structures (one per address family). See
920: draft-ietf-sidrops-rfc6482bis.
921: <li>Check the absence of the Path Length constraint in the Basic
922: Constraints extension.
923: <li>Restrict the SIA extension to only allow the signedObject and
924: rpkiNotify accessMethods.
925: <li>Check that the Signed Object access method is present in ROA, MFT,
926: ASPA, TAK, and GBR End-Entity certificates.
927: <li>In addition to the 'rsync://' scheme, also permit other schemes
928: (such as 'https://') in the SIA signedObject access method.
929: <li>Check that the KeyUsage extension is set to nothing but
930: digitalSignature on End-Entity certificates.
1.16 jsg 931: <li>Check that the KeyUsage extension is set to nothing but keyCertSign
1.13 benno 932: and CRLSign on CA certificates.
933: <li>Check that the ExtendedKeyUsage extension is absent on CA
934: certificates.
935: <li>Fix a bug in the handling of the port of http_proxy.
936: <li>The '-r' command line option has been deprecated.
937: <li>Filemode (-f) output is now presented as a text based table.
938: <li>The 'expires' key in the JSON/CSV/OpenBGPD output formats is now
939: calculated with more accuracy. The calculation takes into account the
940: nextUpdate value of all intermediate CRLs in the signature path
941: towards the trust anchor, in addition to the expiry moment of the
942: leaf-CRL and CAs.
943: <li>Handling of CRLs and Manifests in the face of inconsistent RRDP delta
944: publications has been improved. A copy of an alternative version of
945: the applicable CRL is kept in the staging area of the cache directory,
946: in order to increase the potential for establishing a complete
947: publication point, in cases where a single publication point update
948: was smeared across multiple RRDP delta files.
949: <li>The OpenBGPD configuration output now includes validated Autonomous
950: System Provider Authorization (ASPA) payloads as an 'aspa-set {}'
951: configuration block.
952: <li>When rpki-client is invoked with increased verbosity ('-v'), the
1.46 namn 953: current RRDP Serial and Session ID are shown to aid debugging.
1.13 benno 954: <li>Self-signed X.509 certificates (such as Trust Anchor certificates)
955: now are considered invalid if they contain an X.509
956: AuthorityInfoAccess extension.
957: <li>Signed Objects where the CMS signing-time attribute contains a
958: timestamp later then the X.509 certificate's notAfter timestamp are
959: considered invalid.
960: <li>Manifests where the CMS signing-time attribute contains a timestamp
961: later then the Manifest eContent nextUpdate timestamp are considered
962: invalid.
963: <li>Any objects whose CRL Distribution Points extension contains a
964: CRLIssuer, CRL Reasons, or nameRelativeToCRLIssuer field are
965: considered invalid in accordance with RFC 6487 section 4.8.6.
966: <li>For every X.509 certificate the SHA-1 of the Subject Public Key is
1.46 namn 967: calculated and compared to the Subject Key Identifier (SKI). If a
1.13 benno 968: mismatch is found the certificate is not trusted.
969: <li>Require the outside-TBS signature OID for every X.509 intermediate
970: CA certificate and CRL to be sha256WithRSAEncryption.
971: <li>Require the RSA key pair modulus and public exponent parameters to
972: strictly conform to the RFC 7935 profile.
973: <li>Ensure there is no trailing garbage present in Signed Objects beyond
974: the self-embedded length field.
975: <li>Require RRDP Session IDs to strictly be version 4 UUIDs.
976: <li>When decoding and validating an individual RPKI file using filemode
977: (rpki-client -f file), display the signature path towards the trust
1.46 namn 978: anchor and the timestamp when the signature path will expire.
1.13 benno 979: <li>When decoding and validating an individual RPKI file using filemode
1.46 namn 980: (rpki-client -f file), display the optional CMS signing-time,
981: non-optional X.509 notBefore timestamp and non-optional X.509
982: notAfter timestamp.
1.1 benno 983: </ul>
984:
1.42 tb 985: <li>Updated zlib to 1.2.13.
986:
987: <li>Fixed a long-standing bug in a libreadline header that broke the
988: interactive Python command line interface.
989:
1.22 benno 990: <li>Switched <a href="https://man.openbsd.org/tftpd.8">tftpd(8)</a> to
991: default to read-only unless -w is specified for write access (the
992: previous default).
993: <li>Stopped printing the prompt for non-interactive usage of <a
994: href="https://man.openbsd.org/tftp.1">tftp(1)</a>.
995: <li>Changed <a href="https://man.openbsd.org/rarpd.8">rarpd(8)</a> to
996: only unveil /tftpboot if -t is specified.
997: <li>Added client certificate authentication and an optional SASL
998: EXTERNAL bind to <a
999: href="https://man.openbsd.org/ypldap.8">ypldap(8)</a>.
1000: <li>Adjusted ipv6 address width to align the display columns better
1001: in the output of <a href="https://man.openbsd.org/ndp.8">ndp(8)</a>,
1002: <a href="https://man.openbsd.org/route.8">route(8)</a> and <a
1003: href="https://man.openbsd.org/netstat.1">netstat(1)</a> as already
1004: available in <a
1005: href="https://man.openbsd.org/systat.1">systat(1)</a>'s netstat.
1006: <li>Used <a href="https://man.openbsd.org/stravis.3">stravis(3)</a> to
1007: sanitize redirect URIs from <a
1008: href="https://man.openbsd.org/ftp.1">ftp(1)</a> fetch before printing.
1.35 benno 1009:
1.22 benno 1010: <li>Prevent an <a
1.27 jsg 1011: href="https://man.openbsd.org/unwind.8">unwind(8)</a> crash when a TCP
1.22 benno 1012: query is larger than the length field indicated.
1013: <li>Preserve the original order of nameservers as configured via <a
1014: href="https://man.openbsd.org/resolv.conf.5">resolv.conf(5)</a> in <a
1015: href="https://man.openbsd.org/resolvd.8">resolvd(8)</a>.
1016: <li>Restrict the characters allowed in the hostname argument of <a
1017: href="https://man.openbsd.org/getaddrinfo.3">getaddrinfo(3)</a> to the
1.46 namn 1018: set [A-z0-9-_.]. Additionally, two consecutive dots ('.') are not
1.22 benno 1019: allowed nor can the string start with - or '.'. This removes
1020: characters like '$', '`', '\n' or '*' that can traverse the DNS
1.46 namn 1021: without problems but have special meaning as in a shell.
1.35 benno 1022: <li>Fixed a number of out of bounds reads in DNS response parsing of
1023: the async DNS resolver in libc.
1.22 benno 1024: <li>Added <a
1025: href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a> -M (mac) to
1026: find the mac address on an interface and print it.
1.21 benno 1027: <li>Added support for configuring interfaces by lladdr to support
1.27 jsg 1028: interface configurations bound to a specific hardware device. The "if"
1.21 benno 1029: part of the <a
1030: href="https://man.openbsd.org/hostname.if.5">hostname.if(5)</a>
1031: configuration file can now be a MAC address.
1.22 benno 1032: <li>Limited display of wireguard peers by <a
1033: href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a> to when
1034: either a wireguard interface is specified or the flag "-A" is used.
1035: <li>Implemented the RFC 8781 PREF64 router advertisement option in
1.46 namn 1036: <a href="https://man.openbsd.org/rad.8">rad(8)</a> which is used to
1.22 benno 1037: communicate NAT64 prefixes to hosts.
1038: <li>Moved the documentation of flag mappings displayed by "route show" from the <a
1039: href="https://man.openbsd.org/netstat.1">netstat(1)</a> manpage to <a
1040: href="https://man.openbsd.org/route.8">route(8)</a>.

1215: </ul>
1216:
1.14 benno 1217: <li>OpenSSH 9.3 and OpenSSH 9.2<br>
1218: This release of OpenBSD includes the changes made to OpenSSH since release 9.1:
1.1 benno 1219: <ul>
1220: <li>Security
1221: <ul>
1.14 benno 1222: <li>ssh-add(1): when adding smartcard keys to ssh-agent(1) with the
1223: per-hop destination constraints (ssh-add -h ...) added in OpenSSH
1224: 8.9, a logic error prevented the constraints from being
1225: communicated to the agent. This resulted in the keys being added
1226: without constraints. The common cases of non-smartcard keys and
1227: keys without destination constraints are unaffected. This problem
1228: was reported by Luci Stanescu.
1229: <li>ssh(1): Portable OpenSSH provides an implementation of the
1230: getrrsetbyname(3) function if the standard library does not
1231: provide it, for use by the VerifyHostKeyDNS feature. A
1232: specifically crafted DNS response could cause this function to
1233: perform an out-of-bounds read of adjacent stack data, but this
1.46 namn 1234: condition does not appear to be exploitable beyond denial-of-service
1235: to the ssh(1) client.<br>
1.14 benno 1236: The getrrsetbyname(3) replacement is only included if the system's
1237: standard library lacks this function and portable OpenSSH was not
1238: compiled with the ldns library (--with-ldns). getrrsetbyname(3) is
1239: only invoked if using VerifyHostKeyDNS to fetch SSHFP records. This
1240: problem was found by the Coverity static analyzer.
1241: <li>sshd(8): fix a pre-authentication double-free memory fault
1242: introduced in OpenSSH 9.1. This is not believed to be exploitable,
1243: and it occurs in the unprivileged pre-auth process that is
1244: subject to chroot(2) and is further sandboxed on most major
1245: platforms.
1246: <li>ssh(8): in OpenSSH releases after 8.7, the PermitRemoteOpen option
1247: would ignore its first argument unless it was one of the special
1248: keywords "any" or "none", causing the permission list to fail open
1249: if only one permission was specified. bz3515
1250: <li>ssh(1): if the CanonicalizeHostname and CanonicalizePermittedCNAMEs
1251: options were enabled, and the system/libc resolver did not check
1252: that names in DNS responses were valid, then use of these options
1253: could allow an attacker with control of DNS to include invalid
1254: characters (possibly including wildcards) in names added to
1255: known_hosts files when they were updated. These names would still
1256: have to match the CanonicalizePermittedCNAMEs allow-list, so
1257: practical exploitation appears unlikely.
1258: </ul>
1.1 benno 1259: <li>Potentially-incompatible changes
1.14 benno 1260: <ul>
1261: <li>ssh(1): add a new EnableEscapeCommandline ssh_config(5) option that
1262: controls whether the client-side ~C escape sequence that provides a
1263: command-line is available. Among other things, the ~C command-line
1264: could be used to add additional port-forwards at runtime.<br>
1265: This option defaults to "no", disabling the ~C command-line that
1266: was previously enabled by default. Turning off the command-line
1267: allows platforms that support sandboxing of the ssh(1) client
1268: (currently only OpenBSD) to use a stricter default sandbox policy.
1269: </ul>
1270: <li>New features
1271: <ul>
1272: <li>ssh-keygen(1), ssh-keyscan(1): accept -Ohashalg=sha1|sha256 when
1273: outputting SSHFP fingerprints to allow algorithm selection. bz3493
1274: <li>sshd(8): add a `sshd -G` option that parses and prints the
1275: effective configuration without attempting to load private keys
1276: and perform other checks. This allows usage of the option before
1277: keys have been generated and for configuration evaluation and
1278: verification by unprivileged users.
1279: <li>sshd(8): add support for channel inactivity timeouts via a new
1280: sshd_config(5) ChannelTimeout directive. This allows channels that
1281: have not seen traffic in a configurable interval to be
1282: automatically closed. Different timeouts may be applied to session,
1283: X11, agent and TCP forwarding channels.
1284: <li>sshd(8): add a sshd_config UnusedConnectionTimeout option to
1285: terminate client connections that have no open channels for a
1286: length of time. This complements the ChannelTimeout option above.
1287: <li>sshd(8): add a -V (version) option to sshd like the ssh client has.
1288: <li>ssh(1): add a "Host" line to the output of ssh -G showing the
1289: original hostname argument. bz3343
1290: <li>scp(1), sftp(1): add a -X option to both scp(1) and sftp(1) to
1291: allow control over some SFTP protocol parameters: the copy buffer
1292: length and the number of in-flight requests, both of which are used
1293: during upload/download. Previously these could be controlled in
1294: sftp(1) only. This makes them available in both SFTP protocol
1295: clients using the same option character sequence.
1296: <li>ssh-keyscan(1): allow scanning of complete CIDR address ranges,
1297: e.g. "ssh-keyscan 192.168.0.0/24". If a CIDR range is passed, then
1298: it will be expanded to all possible addresses in the range
1299: including the all-0s and all-1s addresses. bz#976
1300: <li>ssh(1): support dynamic remote port forwarding in escape
1301: command-line's -R processing. bz#3499
1302: </ul>
1.1 benno 1303: <li>Bugfixes
1.14 benno 1304: <ul>
1305: <li>scp(1), sftp(1): fix progressmeter corruption on wide displays;
1306: bz3534
1307: <li>ssh-add(1), ssh-keygen(1): use RSA/SHA256 when testing usability
1308: of private keys as some systems are starting to disable RSA/SHA1
1309: in libcrypto.
1310: <li>sftp-server(8): fix a memory leak. GHPR363
1.16 jsg 1311: <li>ssh(1), sshd(8), ssh-keyscan(1): remove vestigial protocol
1.14 benno 1312: compatibility code and simplify what's left.
1313: <li>Fix a number of low-impact Coverity static analysis findings.
1314: These include several reported via bz2687
1315: <li>ssh_config(5), sshd_config(5): mention that some options are not
1316: first-match-wins.
1317: <li>Rework logging for the regression tests. Regression tests will now
1318: capture separate logs for each ssh and sshd invocation in a test.
1319: <li>ssh(1): make `ssh -Q CASignatureAlgorithms` work as the manpage
1320: says it should; bz3532.
1321: <li>ssh(1): ensure that there is a terminating newline when adding a
1322: new entry to known_hosts; bz3529
1323: <li>ssh(1): when restoring non-blocking mode to stdio fds, restore
1324: exactly the flags that ssh started with and don't just clobber them
1325: with zero, as this could also remove the append flag from the set.
1326: bz3523
1327: <li>ssh(1): avoid printf("%s", NULL) if using UserKnownHostsFile=none
1328: and a hostkey in one of the system known hosts file changes.
1329: <li>scp(1): switch scp from using pipes to a socket-pair for
1330: communication with its ssh sub-processes, matching how sftp(1)
1331: operates.
1332: <li>sshd(8): clear signal mask early in main(); sshd may have been
1333: started with one or more signals masked (sigprocmask(2) is not
1334: cleared on fork/exec) and this could interfere with various things,
1335: e.g. the login grace timer. Execution environments that fail to
1336: clear the signal mask before running sshd are clearly broken, but
1337: apparently they do exist.
1338: <li>ssh(1): warn if no host keys for hostbased auth can be loaded.
1339: <li>sshd(8): Add server debugging for hostbased auth that is queued and
1340: sent to the client after successful authentication, but also logged
1341: to assist in diagnosis of HostbasedAuthentication problems. bz3507
1342: <li>ssh(1): document use of the IdentityFile option as being usable to
1343: list public keys as well as private keys. GHPR352
1344: <li>sshd(8): check for and disallow MaxStartups values less than or
1345: equal to zero during config parsing, rather than failing later at
1346: runtime. bz3489
1347: <li>ssh-keygen(1): fix parsing of hex cert expiry times specified on
1348: the command-line when acting as a CA.
1349: <li>scp(1): when scp(1) is using the SFTP protocol for transport (the
1350: default), better match scp/rcp's handling of globs that don't match
1351: the globbed characters but do match literally (e.g. trying to
1352: transfer a file named "foo.[1]"). Previously scp(1) in SFTP mode
1353: would not match these pathnames but legacy scp/rcp mode would.
1354: bz3488
1355: <li>ssh-agent(1): document the "-O no-restrict-websafe" command-line
1356: option.
1357: <li>ssh(1): honour user's umask(2) if it is more restrictive then the
1358: ssh default (022).

1652: <p>
1653: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1654: This file contains everything you need except for the kernel sources,
1655: which are in a separate archive.
1656: To extract:
1657: <blockquote><pre>
1658: # <kbd>mkdir -p /usr/src</kbd>
1659: # <kbd>cd /usr/src</kbd>
1660: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1661: </pre></blockquote>
1662: <p>
1663: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1664: This file contains all the kernel sources you need to rebuild kernels.
1665: To extract:
1666: <blockquote><pre>
1667: # <kbd>mkdir -p /usr/src/sys</kbd>
1668: # <kbd>cd /usr/src</kbd>
1669: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1670: </pre></blockquote>
1671: <p>
1672: Both of these trees are a regular CVS checkout. Using these trees it
1673: is possible to get a head-start on using the anoncvs servers as
1674: described <a href="anoncvs.html">here</a>.
1675: Using these files
1676: results in a much faster initial CVS update than you could expect from
1677: a fresh checkout of the full OpenBSD source tree.

1687: # <kbd>cd /usr</kbd>
1688: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1689: </pre></blockquote>
1690: <p>
1691: Go read the <a href="faq/ports/index.html">ports</a> page
1692: if you know nothing about ports
1693: at this point. This text is not a manual of how to use ports.
1694: Rather, it is a set of notes meant to kickstart the user on the
1695: OpenBSD ports system.
1696: <p>
1697: The <i>ports/</i> directory represents a CVS checkout of our ports.
1698: As with our complete source tree, our ports tree is available via
1699: <a href="anoncvs.html">AnonCVS</a>.
1700: So, in order to keep up to date with the -stable branch, you must make
1701: the <i>ports/</i> tree available on a read-write medium and update the tree
1702: with a command like:
1703: <blockquote><pre>
1704: # <kbd>cd /usr/ports</kbd>
1705: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_3</kbd>
1706: </pre></blockquote>
1707: <p>
1708: [Of course, you must replace the server name here with a nearby anoncvs
1709: server.]
1710: <p>
1711: Note that most ports are available as packages on our mirrors. Updated
1712: ports for the 7.3 release will be made available if problems arise.
1713: <p>
1714: If you're interested in seeing a port added, would like to help out, or just
1715: would like to know more, the mailing list
1716: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
