71: <h3>What's New</h3>
72: <p>
73: This is a partial list of new features and systems included in OpenBSD 7.3.
74: For a comprehensive list, see the <a href="plus73.html">changelog</a> leading
75: to 7.3.
76:
77: <ul>
78:
79: <li>Various kernel improvements:
80: <ul>
1.41 benno 81:
82:
1.30 jsg 83: <li>Added <a href="https://man.openbsd.org/waitid.2">waitid(2)</a>,
84: wait for process state change.
85: <li>Added <a href="https://man.openbsd.org/pinsyscall.2">pinsyscall(2)</a>,
86: specify the call stub for a specific system call.
87: <li>Added <a href="https://man.openbsd.org/getthrname.2">getthrname(2)</a> and
88: <a href="https://man.openbsd.org/setthrname.2">setthrname(2)</a>,
89: get or set thread name.
1.41 benno 90: <li>Added WTRAPPED option for <a
91: href="https://man.openbsd.org/waitid.2">waitid(2)</a> to control
92: whether CLD_TRAPPED state changes, i.e., ptrace(2) on a process, are reported.
93:
94: <!-- kernel internals -->
1.22 benno 95: <li>Introduced <a
96: href="https://man.openbsd.org/clockintr.9">clockintr(9)</a>, a
1.31 jsg 97: machine-independent clock interrupt scheduler. Switched all
1.22 benno 98: architectures to use this new kernel subsystem.
1.41 benno 99: <li>Added a priority queue to <a
100: href="https://man.openbsd.org/clockintr.9">clockintr(9)</a>.
1.22 benno 101: <li>Introduced a new kern.autoconf_serial <a
102: href="https://man.openbsd.org/sysctl.8">sysctl(8)</a> that can be used
103: by userland to monitor state changes of the kernel device tree.
104: <li>Fixed <a href="https://man.openbsd.org/pmap.9">pmap(9)</a> bugs
105: involving entering an executable mapping for a page before
106: synchronizing the data and instruction cache on arm64 and riscv64.
1.41 benno 107: <li>Removed copystr(9) from public API.
1.22 benno 108: <li>Add <a
109: href="https://man.openbsd.org/getnsecruntime.9">getnsecruntime(9)</a>
110: to the kernel timecounting API. Together with getbinruntime(), it
111: provides a fast, monotonic clock that only advances while the system
112: is not suspended.
1.41 benno 113:
114: <li>Add detection for Spectre-BHB Branch History Injection
115: vulnerability related CLRBHB, ECBHB and CSV2_3/HCXT feature bits.
116:
1.24 jsg 117: <li>Prevent detaching ("bioctl -d detach") of a boot volume on a RAID managed by <a
1.22 benno 118: href="https://man.openbsd.org/bioctl.8">bioctl(8)</a>.
1.41 benno 119:
1.24 jsg 120: <li>On arm64, avoid using 1GB mappings for the identity map in the
1.21 benno 121: early kernel bootstrap phase and when booting the secondary CPUs. This
122: avoids accidentally mapping memory regions that should not be mapped
123: (i.e. secure memory) as all mapped memory can be accessed
124: speculatively.
125: <li>Added arm64 detection of EPAN feature bit. Enhanced Privileged Access Never
126: (EPAN) allows Privileged Access Never to be used with Execute-only mappings.
1.22 benno 127: <li>On arm64, add a machdep.lidaction <a
128: href="https://man.openbsd.org/sysctl.8">sysctl(8)</a> for <a
129: href="https://man.openbsd.org/aplsmc.4">aplsmc(4)</a> Apple Silicon
130: laptops.<br>
131: The arm64 default for the machdep.lidaction is 1, making the
1.13 benno 132: system suspend when the lid is closed. <a
133: href="https://man.openbsd.org/aplsmc.4">aplsmc(4)</a> provides support
134: for the lid position sensor.
135: <li>Changed arm64 suspend idle loop from WFE to WFI, avoiding spurious
136: wakeups while other CPUs are still active.
1.41 benno 137: <li>Added new <a href="https://man.openbsd.org/dt.4">dt(4)</a> tracing ioctl
1.13 benno 138: DTIOCARGS to get the type of probe arguments.
1.1 benno 139: </ul>
140:
141: <li>SMP Improvements

146: <li>Unlocked <a href="https://man.openbsd.org/sched_yield.2">sched_yield(2)</a>.
147: <li>Added support for per-cpu event counters, to be used for clock and
148: IPI counters where the event counted occurs across all CPUs in the
149: system.
150: <li>Moved <a href="https://man.openbsd.org/pf.4">pf(4)</a> purge
151: tasks out from under the kernel lock.
152: <li>Unlocked <a href="https://man.openbsd.org/ioctl.2">ioctl(2)</a>
153: SIOCGIFCONF, SIOCGIFGMEMB, SIOCGIFGATTR, and SIOCGIFGLIST.
154: <li>Protected interface tables in <a
155: href="https://man.openbsd.org/pf.4">pf(4)</a> with PF_LOCK(), allowing
156: removal of NET_LOCK() protection from the <a
157: href="https://man.openbsd.org/ioctl.2">ioctl(2)</a> code path in pf.
158: <li>Unlocked <a
159: href="https://man.openbsd.org/getsockopt.2">getsockopt(2)</a> and <a

166: <li>Stopped holding the vm_map lock while flushing pages in <a
167: href="https://man.openbsd.org/msync.2">msync(2)</a> and <a
168: href="https://man.openbsd.org/madvise.2">madvise(2)</a>. Prevents a
169: 3-thread deadlock between <a
170: href="https://man.openbsd.org/msync.2">msync(2)</a>, page-fault and <a
171: href="https://man.openbsd.org/mmap.2">mmap(2)</a>.
172: <li>Unlocked <a
173: href="https://man.openbsd.org/select.2">select(2)</a>, <a
174: href="https://man.openbsd.org/pselect.2">pselect(2)</a>, <a

187: Radeon RX 7600M (XT), 7700S, 7600S "Navi 33"
1.13 benno 188: <li>Fixed frame buffer corruption and additional bugs after wakeup
189: on Apple Silicon laptops and the Lenovo x13s.
1.22 benno 190: <li>Added support for the backlight connector property to <a
191: href="https://man.openbsd.org/amdgpu.4">amdgpu(4)</a> as in <a
192: href="https://man.openbsd.org/inteldrm.4">inteldrm(4)</a>, making <a
193: href="https://man.openbsd.org/xbacklight.1">xbacklight(1)</a> work
194: when using the Xorg modesetting driver.
1.1 benno 195: </ul>
196:
197: <li>VMM/VMD improvements
198: <ul>
1.22 benno 199: <li>Updated <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> to
200: allow guests to read MSR_HWCR and MSR_PSTATEDEF, which is necessary to
201: determine the TSC frequency on AMD families 17h and 19h.
202: <li>Allocated reference for vm and vcpu SLISTs in <a
203: href="https://man.openbsd.org/vmm.4">vmm(4)</a>, keeping vmm from
204: triggering excessive wakeup calls while iterating through the list of
205: vms while servicing an <a
206: href="https://man.openbsd.org/ioctl.2">ioctl(2)</a>.
207: <li>Set <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> RAX guest
208: register state based on VMCB.
209: <li>Removed locking in <a
210: href="https://man.openbsd.org/vmm.4">vmm(4)</a> vmm_intr_pending,
211: reducing slowdowns due to requests for a lock held while the VM is
212: running.
213: <li>Increased speed of delivery of interrupts to a running vcpu in <a
214: href="https://man.openbsd.org/vmm.4">vmm(4)</a>.
215: <li>Made <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> treat vcpu
216: lists as immutable, removing the need to reference count individual
217: vcpu objects and use a rwlock.
1.13 benno 218: <li>Implemented zero-copy operations on virtqueues in <a
219: href="https://man.openbsd.org/vmd.8">vmd(8)</a>.
220: <li>Provided a detailed e820 memory map when booting <a
221: href="https://man.openbsd.org/vmd.8">vmd(8)</a> guests with SeaBIOS.
222: When a vm initializes memory ranges, we now track what each range
223: represents. This information can be used to supply the e820 memory map
224: to SeaBIOS via the fw_cfg interface allowing it to properly
225: communicate memory ranges to a guest operating system. With this
226: special cases in ports can be removed.
227: <li>Added thread names to vm processes in <a
228: href="https://man.openbsd.org/vmd.8">vmd(8)</a>, visible in <a
229: href="https://man.openbsd.org/ps.1">ps(1)</a>.
230: <li>Hid the WAITPKG cpu feature from <a
231: href="https://man.openbsd.org/vmm.4">vmm(4)</a> guests, preventing
232: invalid instruction exceptions. Also added WAITPKG feature
233: identification to i386 and amd64.
234: <li>Changed <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> to
235: only open /dev/vmm once, having the parent process send the fd to the
236: vmm child process.
1.35 benno 237: <li>Restricted <a href="https://man.openbsd.org/vmm.4">vmm(4)</a>
238: exposed cpuid extended feature flags.
239: <li>Adjusted <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> error
240: paths to avoid removal of configuration-defined (known) VMs on error.
1.13 benno 241: <li>Stopped being paranoid about hypervisor correct PKU handling.<br>
242: Added saving and restoring guest PKRU to <a
243: href="https://man.openbsd.org/vmm.4">vmm(4)</a>. Expose the PKU cpuid
244: bit to the guest if in use on the host.
1.35 benno 245: <li>Made <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> scan the
246: PCI bus to determine bootorder strings.
1.1 benno 247: </ul>
248:
249: <li>Various new userland features:
250: <ul>
1.22 benno 251: <li>Added <a href="https://man.openbsd.org/kdump.1">kdump(1)</a>

255: href="https://man.openbsd.org/mimmutable.2">mimmutable(2)</a> and <a
256: href="https://man.openbsd.org/munmap.2">munmap(2)</a> reporting to <a
257: href="https://man.openbsd.org/kdump.1">kdump(1)</a>.
1.13 benno 258: <li>Added <a
259: href="https://man.openbsd.org/lastcomm.1">lastcomm(1)</a> reporting
260: for process kills due to <a
261: href="https://man.openbsd.org/execve.2">execve(2)</a> from non-pinned
262: syscall address
1.1 benno 263: </ul>
264:
265: <li>Various bugfixes and tweaks in userland:
266: <ul>
1.26 jsg 267: <li>Allow TZ to contain absolute paths starting with /usr/share/zoneinfo.
268: All absolute paths were ignored in 7.2 to avoid

274: <li>Dropped support for $rc_exec in <a
275: href="https://man.openbsd.org/rc.subr.8">rc.subr(8)</a>. The rc_exec
276: function should be used instead.
277: <li>Excluded /tmp/*.shm files from /tmp cleaning in <a
278: href="https://man.openbsd.org/daily.8">daily(8)</a>. Removing them
279: interferes with programs that use shared memory via <a
280: href="https://man.openbsd.org/shm_open.3">shm_open(3)</a>.
281: <li>Added zap-to-char and zap-up-to-char to <a
282: href="https://man.openbsd.org/mg.1">mg(1)</a>. Bound zap-to-char to
283: M-z.
1.37 benno 284: <li>Fixed handling of escaped backslashes in <a

298: display of online CPUs which can change based on the <a
299: href="https://man.openbsd.org/sysctl.2">sysctl(2)</a> sysctl setting.
1.13 benno 300: <li>Added support for a personal <a
301: href="https://man.openbsd.org/units.1">units(1)</a> library by passing
302: -f multiple times.
1.37 benno 303: <li>Changed <a href="https://man.openbsd.org/df.1">df(1)</a> to
304: round up fractional percentages.
305: <li>Fixed unbounded variable expansion in <a
306: href="https://man.openbsd.org/pkg-config.1">pkg-config(1)</a>.
307: <li>Switched to use <a
308: href="https://man.openbsd.org/llvm-strip.1">llvm-strip(1)</a> on
309: architectures that use <a
1.43 krw 310: href="https://man.openbsd.org/ld.lld.1">ld.lld(1)</a>.
1.37 benno 311: <!-- rc scripts -->
1.13 benno 312: <li>Made <a href="https://man.openbsd.org/rc.8">rc(8)</a> reorder
313: libraries in parallel to <a
314: href="https://man.openbsd.org/netstart.8">netstart(8)</a>, as this
315: does not depend on network access.
1.22 benno 316: <li>Made <a href="https://man.openbsd.org/rc.8">rc(8)</a> print the
317: name of each library before relinking as a signal to the operator that
318: boot has not stalled.
1.35 benno 319: <!-- audio -->
1.13 benno 320: <li>Added the <a
321: href="https://man.openbsd.org/audioctl.8">audioctl(8)</a> -w option to
322: display variables periodically.
323: <li>Added short options for <a
324: href="https://man.openbsd.org/timeout.1">timeout(1)</a> --foreground
325: and --preserve-status.<br>
326: Added signal as a full argument name for <a
327: href="https://man.openbsd.org/timeout.1">timeout(1)</a> -s.
328: <li>Fixed .wav files generated by <a
1.35 benno 329: href="https://man.openbsd.org/aucat.1">aucat(1)</a> by using extended
1.13 benno 330: header format.
1.35 benno 331: <!-- disks ... -->
1.13 benno 332: <li>In <a
333: href="https://man.openbsd.org/disklabel.8">disklabel(8)</a>, use the
334: size of the largest chunk of free space, not the total of all such
335: chunks, when checking for sufficient space to add a partition.
1.35 benno 336: <li>Extended <a
337: href="https://man.openbsd.org/disklabel.8">disklabel(8)</a> template
338: parsing to allow "[mount point] *" as the specification for putting
339: the maximum available free space into a partition, and extended
340: command line parsing to allow "T-" as the specification to read the
341: template from stdin.
1.44 krw 342: <li>Repaired <a
343: href="https://man.openbsd.org/disklabel.8">disklabel(8)</a>
344: to check for D_VENDOR flag in d_flags, not d_secpercyl.
345: <li>Removed remnents of DEC standard 144 bad sector code from
346: <a
347: href="https://man.openbsd.org/disklabel.8">disklabel(8)</a>
348: and
349: <a

710: <li>Made <a href="https://man.openbsd.org/installboot.8">installboot(8)</a> silently skip
711: <a href="https://man.openbsd.org/softraid.4">softraid(4)</a>. keydisks.
712: <li>Fixed passing explicit stages files to
713: <a href="https://man.openbsd.org/installboot.8">installboot(8)</a>.
1.38 benno 714: <!-- architecture specific -->
1.22 benno 715: <li>Added <a
716: href="https://man.openbsd.org/mount_nfs.8">mount_nfs(8)</a> to the
717: sparc64 installer, to fetch sets over NFS.
718: <li>Copy the apple-boot firmware to EFI system partition, enabling
719: automatic bootloader updates on Apple Silicon computers.
1.18 kn 720: <li>Made the installer stop printing MD post installation instructions on upgrades.
721: <li>Made it possible to set keyboard layout(s) in arm64's installer.
722: <li>Added initial support in the installer for guided disk
723: encryption for amd64, i386, riscv64 and sparc64.
1.22 benno 724: <li>Added passing of boot device information from the bootloader to
725: the kernel on luna88k.
1.13 benno 726: <li>Switched luna88k boot loader to MI boot code.
1.18 kn 727: <li>Made the luna88k bootloader display a puffy boot logo.
1.13 benno 728: <li>Made <a href="https://man.openbsd.org/ls.1">ls(1)</a> work
729: correctly in the luna88k bootloader.
730: <li>Made <a href="https://man.openbsd.org/time.1">time(1)</a> work
731: correctly in the luna88k bootloader.
732: <li>Removed dangerous user-settable "addr" variable from MI
733: bootloader, only compiling tty-related code on platforms where it
734: makes sense for the bootloader to control it.
735: <li>Added "machine poweroff" command on luna88k bootloader.
736: <li>Switched alpha to machine-independent boot blocks.
1.17 kn 737: <li>Switched all architectures (except alpha and luna88k) ramdisks to use
738: <a href="https://man.openbsd.org/installboot.8">installboot(8)</a> <code>-p</code>.
1.18 kn 739: <li>Fixed ofwboot OpenFirmware <code>map</code> call to unbreak boot on some machines.
1.17 kn 740: <li>Reduced ofwboot.net size after libz update to unbreak netboot on some machines.
741: <li>Made riscv64 bootloader support boot from RAID 1C softraid volumes.
742: <li>Made <a href="https://man.openbsd.org/installboot.8">installboot(8)</a> support
743: <a href="https://man.openbsd.org/softraid.4">softraid(4)</a> on riscv64.
1.45 ! krw 744: <li>Stopped creating defunct Vax (ra, rx), HP-300 (hd) and Sparc (xy, xd)
! 745: devices in /dev.
1.1 benno 746: </ul>
747:
748: <li>Security improvements:
749: <ul>
1.23 benno 750: <li>Permissions (RWX, MAP_STACK, etc) on address space regions can
751: be made <a href="https://man.openbsd.org/mimmutable.2">immutable</a>,
752: so that <a href="https://man.openbsd.org/mmap.2">mmap(2)</a>, <a
753: href="https://man.openbsd.org/mprotect.2">mprotect(2)</a> or <a
754: href="https://man.openbsd.org/munmap.2">munmap(2)</a> fail with EPERM.
755: Most of the program static address space is now automatically
756: immutable (main program, ld.so, main stack, load-time shared
757: libraries, and dlopen()'d libraries mapped without RTLD_NODELETE).
758: Programmers can request non-immutable static data using the
759: "openbsd.mutable" section, or manually bring immutability to (page
760: aligned heap objects) using <a
761: href="https://man.openbsd.org/mimmutable.2">mimmutable(2)</a>.
762: <li>Some architectures now have non-readable code ("xonly"), both from
763: the perspective of userland reading its own memory, or the kernel
764: trying to read memory in a system call. Many sloppy practices in
765: userland code had to be repaired to allow this. The <a
766: href="https://man.openbsd.org/ld.lld.1">linker (ld.lld(1))</a> option
767: --execute-only is enabled by default. In order of development: arm64,
768: riscv64, hppa, amd64, powerpc64, powerpc (G5 only), octeon. sparc64
769: (sun4u only, unfinished).
770: <li>On all architectures which lack hardware-enforcement of xonly,
771: system calls are now prevented from reading (via <a
772: href="https://man.openbsd.org/copyin.9">copyin(9)</a>/copyinst)
773: inside the program's main text, ld.so text, sigtramp text, or libc.so
774: text.
775: <li>can still benefit from switching to --execute-only binaries if the
776: cpu generates different traps for instruction-fetch versus data-fetch.
777: The VM system will not allow memory to be read before it was executed
778: which is valuable together with library relinking. Architectures
779: switched over include loongson.
780: <li><a href="https://man.openbsd.org/ld.so.1">ld.so(1)</a> and crt0
781: register the location of the <a
782: href="https://man.openbsd.org/execve.2">execve(2)</a> stub with the
783: kernel using pinsyscall(2), after which the kernel only accepts an
784: execve call from that specific location.
1.13 benno 785: <li>Added <a href="https://man.openbsd.org/execve.2">execve(2)</a>
786: violations of <a
787: href="https://man.openbsd.org/pinsyscall.2">pinsyscall(2)</a> policy
788: to the daily mail, available by setting rc.conf.local(5)
789: accounting=YES.
1.23 benno 790: <li>Added retguard (consistency-check the return address on the
791: stack) to amd64 syscalls.
792: <li>sshd random relinking at boot: Randomly relink and install <a
793: href="https://man.openbsd.org/sshd.8">sshd(8)</a>, resulting
794: in a sshd binary with unknown address layout after every reboot.
1.13 benno 795: <li>Add another mitigation against classic BROP on systems without
796: execute-only mmu hardware-enforcement. A range-checking wrapper in
1.23 benno 797: front of <a href="https://man.openbsd.org/copyin.9">copyin(9)</a> and
1.33 tj 798: <a href="https://man.openbsd.org/copyinstr.9">copyinstr(9)</a> ensures
1.23 benno 799: the userland source address doesn't overlap the main program text and
800: other text segments, thereby making this address ranges unreadable to
801: the kernel. No programs have been discovered which require reading
802: their own text segments with a system call.
1.22 benno 803: <li>On arm64, introduce mitigation of the Spectre-BHB (Branch
804: History Injection) CPU vulnerability by using core-specific trampoline
805: vectors.
1.23 benno 806: <li>Enabled the arm64 Data Independent Timing (DIT) feature in both the kernel and
807: userland on CPUs that support it to mitigate timing side-channel
1.22 benno 808: attacks.
1.1 benno 809: </ul>
810:
811: <li>Changes in the network stack:
812: <ul>
1.24 jsg 813: <li>Made /dev/pf a clonable device to better track kernel resources
1.22 benno 814: used by processes.
815: <li>Modified TCP receive buffer size auto-scaling to use the smoothed
816: RTT (SRTT) instead of the timestamp option, which improves performance
817: on high latency networks if the timestamp option isn't available.
1.24 jsg 818: <li>Relaxed the requirement for multicast support of interfaces for
1.22 benno 819: configuring IPv6. This allows non-multicast interfaces such as
820: point-to-point interfaces and the NBMA / point-to-multipoint
821: interfaces like mpe(4), mgre(4) and wg(4) to work with IPv6.
822: <li>Use the new <a
823: href="https://man.openbsd.org/getnsecruntime.9">getnsecruntime(9)</a>
824: timer to check the TCP_KEEPALIVE timer only against the system
825: runtime, not the uptime. Prevents TCP connections to fail after
1.24 jsg 826: waking up from suspend.
1.13 benno 827: <li>Used stoeplitz (symmetric Toeplitz hash algorithm) to generate a
828: hash/flowid for <a href="https://man.openbsd.org/pf.4">pf(4)</a> state
829: keys. With this change, pf will hash traffic the same way that
830: hardware using a stoeplitz key will hash incoming traffic on rings.
1.27 jsg 831: stoeplitz is also used by the TCP stack to generate a flow id, which
1.13 benno 832: is used to pick which transmit ring is used on nics with multiple
833: queues too. using the same algorithm throughout the stack encourages
834: affinity of packets to rings and softnet threads the whole way
835: through.
836: <li>Prevented possible kernel crashes by dropping TCP packets with
837: destination port 0 in <a href="https://man.openbsd.org/pf.4">pf(4)</a>
838: and the stack.
1.33 tj 839: <li>Fixed an endian swap bug causing problems with <a
1.27 jsg 840: href="https://man.openbsd.org/vlan.4">vlan(4)</a> on <a
1.13 benno 841: href="https://man.openbsd.org/em.4">em(4)</a> sparc64 systems.
842: <li>Denied "pipex no" tunnel setting for <a
843: href="https://man.openbsd.org/pppx.4">pppx(4)</a> interfaces.
1.22 benno 844: <li>Fixed <a href="https://man.openbsd.org/pfsync.4">pfsync(4)</a>
845: crashing on pf_state_key removal.
1.13 benno 846: <li>Fixed a panic in <a
847: href="https://man.openbsd.org/pfsync.4">pfsync(4)</a> when there are
848: no data ready for bulk transfer.
849: <li>Turned off TCP Segmentation Offload (TSO) if interface is added
850: to layer 2 devices.
851: <li>Improved <a href="https://man.openbsd.org/vnet.4">vnet(4)</a>
852: to work better in busy conditions.
853: <li>Added a <a href="https://man.openbsd.org/bpf.4">bpf(4)</a> timeout
854: (BIOCSWTIMEOUT) between capturing a packet and making the buffer
855: readable, preventing for example <a
856: href="https://man.openbsd.org/pflogd.8">pflogd(8)</a> waking every
857: half second even if there is nothing to read. By default this buffer
858: is infinite and must be filled to become readable.
859: <li>Avoided enabling TSO on interfaces which are already attached to a bridge.
860: </ul>
1.1 benno 861:
862: <li>Routing daemons and other userland network improvements:
863: <ul>
864: <li>IPsec support was improved:
865: <ul>
1.13 benno 866: <li>Added <a href="https://man.openbsd.org/iked.8">iked(8)</a>
867: support for configuring multiple name servers.
868: <li>Synced proc.c from <a
869: href="https://man.openbsd.org/vmd.8">vmd(8)</a> to <a
870: href="https://man.openbsd.org/iked.8">iked(8)</a> to enabled fork +
871: exec for all processes. This gives each process a fresh and unique
872: address space to further improve randomization of ASLR and stack
873: protector.
874: </ul>
875: <li>In <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>, <a
876: href="https://man.openbsd.org/bgpctl.8">bgpctl(8)</a> and <a
877: href="https://man.openbsd.org/bgplgd.8">bgplgd(8)</a>:
878: <ul>
879: <li>Improved performance by optimising the output filters
1.16 jsg 880: <li>Add Autonomous System Provider Authorization (ASPA) validation
1.13 benno 881: based on draft-ietf-sidrops-aspa-verification-12
882: <li>Introduce avs (ASPA validation state) filter and bgpctl
883: filter argument
1.38 benno 884: <li>Add ASPA support for the RTR protocol based on
1.13 benno 885: draft-ietf-sidrops-8210bis-10
1.38 benno 886: <li>Improve open policy (RFC 9234) support and enable the capability
1.13 benno 887: automatically if a role is specified for the peer
1.38 benno 888: <li>Introduce a per neighbor 'role' configuration option to specify
1.13 benno 889: the session role used by ASPA verification and the open policy
890: capability. The 'announce policy' statement was simplified at
891: the same time.
1.38 benno 892: <li>Improve startup behaviour by introducing a small delay before
1.13 benno 893: opening the connection to a new peer
1.38 benno 894: <li>Support for aspa-set table config which can be provided by
1.13 benno 895: <a
896: href="https://man.openbsd.org/rpki-client.8">rpki-client(8)</a>
1.38 benno 897: <li>Make it possible to filter the RIB by invalid and leaked prefixes
1.13 benno 898: in bgpctl and bgplgd
1.38 benno 899: <li>Add OpenMetrics output to bgpctl for various BGP statistics and
1.13 benno 900: add /metrics endpoint to bgplgd
1.38 benno 901: <li>Fix of incorrect length checks that allowed an out-of-bounds
1.13 benno 902: read in bgpd.
1.1 benno 903: </ul>
904: <li><a href="https://man.openbsd.org/rpki-client.8">rpki-client(8)</a> saw some changes:
905: <ul>
1.13 benno 906: <li>Add a new '-H' command line option to create a shortlist of
907: repositories to synchronize to. For example, when invoking
908: "rpki-client -H rpki.ripe.net -H chloe.sobornost.net", the utility
909: will not connect to any other hosts other than the two specified
910: through the -H option.
911: <li>Add support for validating Geofeed (RFC 9092) authenticators. To
912: see an example download https://sobornost.net/geofeed.csv and run
913: "rpki-client -f geofeed.csv"
914: <li>Add support for validating Trust Anchor Key (TAK) objects. TAK
915: objects can be used to produce new Trust Anchor Locators (TALs) signed
916: by and verified against the previous Trust Anchor. See
917: draft-ietf-sidrops-signed-tal for the full specification.
918: <li>Log lines related to RRDP/HTTPS connection problems now include the
919: IP address of the problematic endpoint (in brackets).
920: <li>Improve the error message when an invalid filename is encountered
921: in the rpkiManifest field in the Subject Access Information (SIA)
922: extension.
923: <li>Emit a warning when unexpected X.509 extensions are encountered.
924: <li>Restrict the ROA ipAddrBlocks field to only allow two
925: ROAIPAddressFamily structures (one per address family). See
926: draft-ietf-sidrops-rfc6482bis.
927: <li>Check the absence of the Path Length constraint in the Basic
928: Constraints extension.
929: <li>Restrict the SIA extension to only allow the signedObject and
930: rpkiNotify accessMethods.
931: <li>Check that the Signed Object access method is present in ROA, MFT,
932: ASPA, TAK, and GBR End-Entity certificates.
933: <li>In addition to the 'rsync://' scheme, also permit other schemes
934: (such as 'https://') in the SIA signedObject access method.
935: <li>Check that the KeyUsage extension is set to nothing but
936: digitalSignature on End-Entity certificates.
1.16 jsg 937: <li>Check that the KeyUsage extension is set to nothing but keyCertSign
1.13 benno 938: and CRLSign on CA certificates.
939: <li>Check that the ExtendedKeyUsage extension is absent on CA
940: certificates.
941: <li>Fix a bug in the handling of the port of http_proxy.
942: <li>The '-r' command line option has been deprecated.
943: <li>Filemode (-f) output is now presented as a text based table.
944: <li>The 'expires' key in the JSON/CSV/OpenBGPD output formats is now
945: calculated with more accuracy. The calculation takes into account the
946: nextUpdate value of all intermediate CRLs in the signature path
947: towards the trust anchor, in addition to the expiry moment of the
948: leaf-CRL and CAs.
949: <li>Handling of CRLs and Manifests in the face of inconsistent RRDP delta
950: publications has been improved. A copy of an alternative version of
951: the applicable CRL is kept in the staging area of the cache directory,
952: in order to increase the potential for establishing a complete
953: publication point, in cases where a single publication point update
954: was smeared across multiple RRDP delta files.
955: <li>The OpenBGPD configuration output now includes validated Autonomous
956: System Provider Authorization (ASPA) payloads as an 'aspa-set {}'
957: configuration block.
958: <li>When rpki-client is invoked with increased verbosity ('-v'), the
959: current RRDP Serial & Session ID are shown to aid debugging.
960: <li>Self-signed X.509 certificates (such as Trust Anchor certificates)
961: now are considered invalid if they contain an X.509
962: AuthorityInfoAccess extension.
963: <li>Signed Objects where the CMS signing-time attribute contains a
964: timestamp later then the X.509 certificate's notAfter timestamp are
965: considered invalid.
966: <li>Manifests where the CMS signing-time attribute contains a timestamp
967: later then the Manifest eContent nextUpdate timestamp are considered
968: invalid.
969: <li>Any objects whose CRL Distribution Points extension contains a
970: CRLIssuer, CRL Reasons, or nameRelativeToCRLIssuer field are
971: considered invalid in accordance with RFC 6487 section 4.8.6.
972: <li>For every X.509 certificate the SHA-1 of the Subject Public Key is
973: calculated and compared to the Subject Key Identifier (SKI), if a
974: mismatch is found the certificate is not trusted.
975: <li>Require the outside-TBS signature OID for every X.509 intermediate
976: CA certificate and CRL to be sha256WithRSAEncryption.
977: <li>Require the RSA key pair modulus and public exponent parameters to
978: strictly conform to the RFC 7935 profile.
979: <li>Ensure there is no trailing garbage present in Signed Objects beyond
980: the self-embedded length field.
981: <li>Require RRDP Session IDs to strictly be version 4 UUIDs.
982: <li>When decoding and validating an individual RPKI file using filemode
983: (rpki-client -f file), display the signature path towards the trust
984: anchor, and the timestamp when the signature path will expire.
985: <li>When decoding and validating an individual RPKI file using filemode
986: (rpki-client -f file), display the optional CMS signing-time, and
987: non-optional X.509 notBefore, and X.509 notAfter timestamps.
1.1 benno 988: </ul>
989:
1.42 tb 990: <li>Updated zlib to 1.2.13.
991:
992: <li>Fixed a long-standing bug in a libreadline header that broke the
993: interactive Python command line interface.
994:
1.22 benno 995: <li>Switched <a href="https://man.openbsd.org/tftpd.8">tftpd(8)</a> to
996: default to read-only unless -w is specified for write access (the
997: previous default).
998: <li>Stopped printing the prompt for non-interactive usage of <a
999: href="https://man.openbsd.org/tftp.1">tftp(1)</a>.
1000: <li>Changed <a href="https://man.openbsd.org/rarpd.8">rarpd(8)</a> to
1001: only unveil /tftpboot if -t is specified.
1002: <li>Added client certificate authentication and an optional SASL
1003: EXTERNAL bind to <a
1004: href="https://man.openbsd.org/ypldap.8">ypldap(8)</a>.
1005: <li>Adjusted ipv6 address width to align the display columns better
1006: in the output of <a href="https://man.openbsd.org/ndp.8">ndp(8)</a>,
1007: <a href="https://man.openbsd.org/route.8">route(8)</a> and <a
1008: href="https://man.openbsd.org/netstat.1">netstat(1)</a> as already
1009: available in <a
1010: href="https://man.openbsd.org/systat.1">systat(1)</a>'s netstat.
1011: <li>Used <a href="https://man.openbsd.org/stravis.3">stravis(3)</a> to
1012: sanitize redirect URIs from <a
1013: href="https://man.openbsd.org/ftp.1">ftp(1)</a> fetch before printing.
1.35 benno 1014:
1.22 benno 1015: <li>Prevent an <a
1.27 jsg 1016: href="https://man.openbsd.org/unwind.8">unwind(8)</a> crash when a TCP
1.22 benno 1017: query is larger than the length field indicated.
1018: <li>Preserve the original order of nameservers as configured via <a
1019: href="https://man.openbsd.org/resolv.conf.5">resolv.conf(5)</a> in <a
1020: href="https://man.openbsd.org/resolvd.8">resolvd(8)</a>.
1021: <li>Restrict the characters allowed in the hostname argument of <a
1022: href="https://man.openbsd.org/getaddrinfo.3">getaddrinfo(3)</a> to the
1023: set [A-z0-9-_.]. Additionally two consecutive dots ('.') are not
1024: allowed nor can the string start with - or '.'. This removes
1025: characters like '$', '`', '\n' or '*' that can traverse the DNS
1026: without problems, but have special meaning, for example a shell.
1.35 benno 1027: <li>Fixed a number of out of bounds reads in DNS response parsing of
1028: the async DNS resolver in libc.
1.22 benno 1029: <li>Added <a
1030: href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a> -M (mac) to
1031: find the mac address on an interface and print it.
1.21 benno 1032: <li>Added support for configuring interfaces by lladdr to support
1.27 jsg 1033: interface configurations bound to a specific hardware device. The "if"
1.21 benno 1034: part of the <a
1035: href="https://man.openbsd.org/hostname.if.5">hostname.if(5)</a>
1036: configuration file can now be a MAC address.
1.22 benno 1037: <li>Limited display of wireguard peers by <a
1038: href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a> to when
1039: either a wireguard interface is specified or the flag "-A" is used.
1040: <li>Implemented the RFC 8781 PREF64 router advertisement option in
1041: <a href="https://man.openbsd.org/rad.8">rad(8)</a> which is used to o
1042: communicate NAT64 prefixes to hosts.
1043: <li>Moved the documentation of flag mappings displayed by "route show" from the <a
1044: href="https://man.openbsd.org/netstat.1">netstat(1)</a> manpage to <a
1045: href="https://man.openbsd.org/route.8">route(8)</a>.
1046: <li>Improvements in <a href="https://man.openbsd.org/nc.1">nc(1)</a>:
1047: <ul>
1.27 jsg 1048: <li>Stop claiming connection success in UDP mode unless true.
1.22 benno 1049: <li>Do not test the connection in non-interactive mode. The test
1050: writes characters to the socket which can corrupt data that is
1051: possible piped into nc.
1.42 tb 1052: <li>Some refactoring and code cleanup.
1.22 benno 1053: </ul>
1054:
1.42 tb 1055: <li>Improvements in

1218: </ul>
1219:
1.14 benno 1220: <li>OpenSSH 9.3 and OpenSSH 9.2<br>
1221: This release of OpenBSD includes the changes made to OpenSSH since release 9.1:
1.1 benno 1222: <ul>
1223: <li>Security
1224: <ul>
1.14 benno 1225: <li>ssh-add(1): when adding smartcard keys to ssh-agent(1) with the
1226: per-hop destination constraints (ssh-add -h ...) added in OpenSSH
1227: 8.9, a logic error prevented the constraints from being
1228: communicated to the agent. This resulted in the keys being added
1229: without constraints. The common cases of non-smartcard keys and
1230: keys without destination constraints are unaffected. This problem
1231: was reported by Luci Stanescu.
1232: <li>ssh(1): Portable OpenSSH provides an implementation of the
1233: getrrsetbyname(3) function if the standard library does not
1234: provide it, for use by the VerifyHostKeyDNS feature. A
1235: specifically crafted DNS response could cause this function to
1236: perform an out-of-bounds read of adjacent stack data, but this
1237: condition does not appear to be exploitable beyond denial-of-
1238: service to the ssh(1) client.<br>
1239: The getrrsetbyname(3) replacement is only included if the system's
1240: standard library lacks this function and portable OpenSSH was not
1241: compiled with the ldns library (--with-ldns). getrrsetbyname(3) is
1242: only invoked if using VerifyHostKeyDNS to fetch SSHFP records. This
1243: problem was found by the Coverity static analyzer.
1244: <li>sshd(8): fix a pre-authentication double-free memory fault
1245: introduced in OpenSSH 9.1. This is not believed to be exploitable,
1246: and it occurs in the unprivileged pre-auth process that is
1247: subject to chroot(2) and is further sandboxed on most major
1248: platforms.
1249: <li>ssh(8): in OpenSSH releases after 8.7, the PermitRemoteOpen option
1250: would ignore its first argument unless it was one of the special
1251: keywords "any" or "none", causing the permission list to fail open
1252: if only one permission was specified. bz3515
1253: <li>ssh(1): if the CanonicalizeHostname and CanonicalizePermittedCNAMEs
1254: options were enabled, and the system/libc resolver did not check
1255: that names in DNS responses were valid, then use of these options
1256: could allow an attacker with control of DNS to include invalid
1257: characters (possibly including wildcards) in names added to
1258: known_hosts files when they were updated. These names would still
1259: have to match the CanonicalizePermittedCNAMEs allow-list, so
1260: practical exploitation appears unlikely.
1261: </ul>
1.1 benno 1262: <li>Potentially-incompatible changes
1.14 benno 1263: <ul>
1264: <li>ssh(1): add a new EnableEscapeCommandline ssh_config(5) option that
1265: controls whether the client-side ~C escape sequence that provides a
1266: command-line is available. Among other things, the ~C command-line
1267: could be used to add additional port-forwards at runtime.<br>
1268: This option defaults to "no", disabling the ~C command-line that
1269: was previously enabled by default. Turning off the command-line
1270: allows platforms that support sandboxing of the ssh(1) client
1271: (currently only OpenBSD) to use a stricter default sandbox policy.
1272: </ul>
1273: <li>New features
1274: <ul>
1275: <li>ssh-keygen(1), ssh-keyscan(1): accept -Ohashalg=sha1|sha256 when
1276: outputting SSHFP fingerprints to allow algorithm selection. bz3493
1277: <li>sshd(8): add a `sshd -G` option that parses and prints the
1278: effective configuration without attempting to load private keys
1279: and perform other checks. This allows usage of the option before
1280: keys have been generated and for configuration evaluation and
1281: verification by unprivileged users.
1282: <li>sshd(8): add support for channel inactivity timeouts via a new
1283: sshd_config(5) ChannelTimeout directive. This allows channels that
1284: have not seen traffic in a configurable interval to be
1285: automatically closed. Different timeouts may be applied to session,
1286: X11, agent and TCP forwarding channels.
1287: <li>sshd(8): add a sshd_config UnusedConnectionTimeout option to
1288: terminate client connections that have no open channels for a
1289: length of time. This complements the ChannelTimeout option above.
1290: <li>sshd(8): add a -V (version) option to sshd like the ssh client has.
1291: <li>ssh(1): add a "Host" line to the output of ssh -G showing the
1292: original hostname argument. bz3343
1293: <li>scp(1), sftp(1): add a -X option to both scp(1) and sftp(1) to
1294: allow control over some SFTP protocol parameters: the copy buffer
1295: length and the number of in-flight requests, both of which are used
1296: during upload/download. Previously these could be controlled in
1297: sftp(1) only. This makes them available in both SFTP protocol
1298: clients using the same option character sequence.
1299: <li>ssh-keyscan(1): allow scanning of complete CIDR address ranges,
1300: e.g. "ssh-keyscan 192.168.0.0/24". If a CIDR range is passed, then
1301: it will be expanded to all possible addresses in the range
1302: including the all-0s and all-1s addresses. bz#976
1303: <li>ssh(1): support dynamic remote port forwarding in escape
1304: command-line's -R processing. bz#3499
1305: </ul>
1.1 benno 1306: <li>Bugfixes
1.14 benno 1307: <ul>
1308: <li>scp(1), sftp(1): fix progressmeter corruption on wide displays;
1309: bz3534
1310: <li>ssh-add(1), ssh-keygen(1): use RSA/SHA256 when testing usability
1311: of private keys as some systems are starting to disable RSA/SHA1
1312: in libcrypto.
1313: <li>sftp-server(8): fix a memory leak. GHPR363
1.16 jsg 1314: <li>ssh(1), sshd(8), ssh-keyscan(1): remove vestigial protocol
1.14 benno 1315: compatibility code and simplify what's left.
1316: <li>Fix a number of low-impact Coverity static analysis findings.
1317: These include several reported via bz2687
1318: <li>ssh_config(5), sshd_config(5): mention that some options are not
1319: first-match-wins.
1320: <li>Rework logging for the regression tests. Regression tests will now
1321: capture separate logs for each ssh and sshd invocation in a test.
1322: <li>ssh(1): make `ssh -Q CASignatureAlgorithms` work as the manpage
1323: says it should; bz3532.
1324: <li>ssh(1): ensure that there is a terminating newline when adding a
1325: new entry to known_hosts; bz3529
1326: <li>ssh(1): when restoring non-blocking mode to stdio fds, restore
1327: exactly the flags that ssh started with and don't just clobber them
1328: with zero, as this could also remove the append flag from the set.
1329: bz3523
1330: <li>ssh(1): avoid printf("%s", NULL) if using UserKnownHostsFile=none
1331: and a hostkey in one of the system known hosts file changes.
1332: <li>scp(1): switch scp from using pipes to a socket-pair for
1333: communication with its ssh sub-processes, matching how sftp(1)
1334: operates.
1335: <li>sshd(8): clear signal mask early in main(); sshd may have been
1336: started with one or more signals masked (sigprocmask(2) is not
1337: cleared on fork/exec) and this could interfere with various things,
1338: e.g. the login grace timer. Execution environments that fail to
1339: clear the signal mask before running sshd are clearly broken, but
1340: apparently they do exist.
1341: <li>ssh(1): warn if no host keys for hostbased auth can be loaded.
1342: <li>sshd(8): Add server debugging for hostbased auth that is queued and
1343: sent to the client after successful authentication, but also logged
1344: to assist in diagnosis of HostbasedAuthentication problems. bz3507
1345: <li>ssh(1): document use of the IdentityFile option as being usable to
1346: list public keys as well as private keys. GHPR352
1347: <li>sshd(8): check for and disallow MaxStartups values less than or
1348: equal to zero during config parsing, rather than failing later at
1349: runtime. bz3489
1350: <li>ssh-keygen(1): fix parsing of hex cert expiry times specified on
1351: the command-line when acting as a CA.
1352: <li>scp(1): when scp(1) is using the SFTP protocol for transport (the
1353: default), better match scp/rcp's handling of globs that don't match
1354: the globbed characters but do match literally (e.g. trying to
1355: transfer a file named "foo.[1]"). Previously scp(1) in SFTP mode
1356: would not match these pathnames but legacy scp/rcp mode would.
1357: bz3488
1358: <li>ssh-agent(1): document the "-O no-restrict-websafe" command-line
1359: option.
1360: <li>ssh(1): honour user's umask(2) if it is more restrictive then the
1361: ssh default (022).

1654: <h3>Notes about the source code</h3>
1655: <p>
1656: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1657: This file contains everything you need except for the kernel sources,
1658: which are in a separate archive.
1659: To extract:
1660: <blockquote><pre>
1661: # <kbd>mkdir -p /usr/src</kbd>
1662: # <kbd>cd /usr/src</kbd>
1663: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1664: </pre></blockquote>
1665: <p>
1666: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1667: This file contains all the kernel sources you need to rebuild kernels.
1668: To extract:
1669: <blockquote><pre>
1670: # <kbd>mkdir -p /usr/src/sys</kbd>
1671: # <kbd>cd /usr/src</kbd>
1672: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1673: </pre></blockquote>
1674: <p>
1675: Both of these trees are a regular CVS checkout. Using these trees it
1676: is possible to get a head-start on using the anoncvs servers as
1677: described <a href="anoncvs.html">here</a>.
1678: Using these files
1679: results in a much faster initial CVS update than you could expect from
1680: a fresh checkout of the full OpenBSD source tree.

1688: A ports tree archive is also provided. To extract:
1689: <blockquote><pre>
1690: # <kbd>cd /usr</kbd>
1691: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1692: </pre></blockquote>
1693: <p>
1694: Go read the <a href="faq/ports/index.html">ports</a> page
1695: if you know nothing about ports
1696: at this point. This text is not a manual of how to use ports.
1697: Rather, it is a set of notes meant to kickstart the user on the
1698: OpenBSD ports system.
1699: <p>
1700: The <i>ports/</i> directory represents a CVS checkout of our ports.
1701: As with our complete source tree, our ports tree is available via
1702: <a href="anoncvs.html">AnonCVS</a>.
1703: So, in order to keep up to date with the -stable branch, you must make
1704: the <i>ports/</i> tree available on a read-write medium and update the tree
1705: with a command like:
1706: <blockquote><pre>
1707: # <kbd>cd /usr/ports</kbd>
1708: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_3</kbd>
1709: </pre></blockquote>
1710: <p>
1711: [Of course, you must replace the server name here with a nearby anoncvs
1712: server.]
1713: <p>
1714: Note that most ports are available as packages on our mirrors. Updated
1715: ports for the 7.3 release will be made available if problems arise.
1716: <p>
1717: If you're interested in seeing a port added, would like to help out, or just
1718: would like to know more, the mailing list
1719: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
