What's New

This is a partial list of new features and systems included in OpenBSD 7.2. For a comprehensive list, see the changelog leading to 7.2.

• New/extended platforms:
  • Added support for Ampere Altra
  • Added support for Apple M2
  • Added support for Lenovo ThinkPad x13s and other machines using the Qualcomm Snapdragon 8cx Gen 3 (SC8280XP) SoC.
• Various kernel improvements:
  • Allowed bsd.rd and bsd/bsd.mp to boot on Oracle Cloud amd64 instances.
  • Added support for switching from glass console to serial console on arm64 systems that default to glass console.
  • pf(4) automatically allows IGMP and ICMP6 MLD packets with the router alert option. Special allow-opts rules are no longer needed for multicast discovery.
  • Fixed a pf(4) NULL dereference panic triggered by relayd(8).
  • Implement "show all routes" to print routing tables in ddb(4).
  • Added a method (ESC D) to enter ddb(4) on serial drivers that do not have a true BREAK mechanism.
  • Added "show all routes" and the ability to show individual routes (e.g. "show route 0xfffffd807e9b0000") to ddb(4).
  • Added a "show swap" command to ddb(4) to help debugging.
  • Count dropped network packets due to low memory in netstat(1).
  • Simplified machine command handling in ddb(4).
  • Changed to a simpler formula to calculate a default kern.maxthread value: 2*NPROCESS.
  • Enabled kstat(4), a device that exports kernel statistics that can be read by kstat(1).
  • Added CPU frequency sensors for each core on CPUs that have MPERF/APERF support.
  • Merged the UVM swap-backed and object-backed inactive page lists.
  • Fixed rwlock(9) implementation to be fair to writers. Previously, readers could grab the lock even if writers were waiting first.
  • Made the CPU frequency scaling duration relative to the load when in automatic mode on battery.
  • Fixed luna88k MULTIPROCESSOR kernels booting with CPU modules installed in arbitrary slots.
  • Added a missing kqueue(2) wakeup, found by a Go testcase hang.
  • Bumped the maximum number of supported CPUs to 256 on arm64.
  • Ensure uvm_swap_io() can succeed, even in out of memory situations, by reserving a second segment for the page daemon.
  • Ensured progress in the swapper by pre-allocating pages in a DMA-reachable region.
  • Made the page daemon consider pmemrange regions when trying to free pages from the inactive list. Previously the page daemon could use a lot of CPU without freeing a page because the global limits were satisfied.
  • Ensured that uvm_swap_get() will always sleep rather than returning an error. Previously an error could be returned to the fault handler which would result in processes dying when a system was under a lot of memory pressure.
  • Added support for using non-standard UARTs (such as the Synopsys DesignWare UART) as an early console.
  • Remove NexGen CPU identification code as the kernel cannot run on these CPUs anyway.
  • Remove Rise CPU identification code.
  • Dropped detection code for 386sx/386dx CPUs. OpenBSD/i386 hasn't actually supported running on either for some time.
  • Dropped detection code for Cyrix CPUs older than the Cyrix M2.
  • Implemented the fundamentals for suspend/resume on arm64.
  • Simplified TSC synchronization testing on amd64.
  • Corrected sparc64 ofwboot to default to the softraid(4) volume on the boot device to make root on softraid work out of the box on sparc64 and be more consistent with softraid boot on other architectures.
  • Removed the obsolete kern.nselcoll sysctl(2).
  • Changed mips64, octeon, and loongson to trigger deferred clock interrupts from splx(9). This isolates the clock interrupt schedule from the MD clock interrupt code.
  • Fixed a potential kernel panic when an msdos partition is out of space by fixing instances where msdosfs passed a NULL proc pointer to detrunc().
  • Add a delay_init() function that helps on i386 and amd64 architectures in setting up delay_func for different timers and switching between them depending on their quality properties. This improves how timers backing delay(9) are managed.
  • Ensured disklabel(5) is read from/written to disk only from/to unused space or an OpenBSD partition.
  • Ensured GPT header data is not used until all validity checks are passed.
  • Corrected handling of GPT usable LBA start/end values, preventing incorrect fallback to MBR partitioning.
  • Ignored size of OpenBSD GPT partition when searching for the disklabel(5), as has always been done for MBR OpenBSD partition.
• SMP Improvements
  • Make route timer MP safe and use rttimer pool.
  • Use kernel lock to protect parts of ARP, ND6 and PPPoE that are not MP safe. Lookup of existing ARP entries is MP safe and can run in parallel.
  • Start up to 4 softnet tasks to run IP input and forwarding in parallel on multiple cores.
  • Run IPv4 packet reassembly in parallel.
  • Run IPv6 hop-by-hop options processing in parallel.
  • Add a mutex to rate limiting functions to make them MP safe.
  • Introduce mutex and reference counter for internet protocol control block.
  • Protect UDP, raw IP, and divert packet input routines with a per-socket mutex.
  • Protect recv(2) system call for UDP and raw IP packets with a per-socket mutex and shared netlock. Allows to receive packets while forwarding in parallel.
  • Protect multicast deliver loop for UDP and raw IP sockets with rwlock.
  • Only grab netlock in IGMP and MLD timer when necessary.
  • TCP slow timer runs without netlock.
  • Rework rwlock so that a writer will get the lock eventually. Readers cannot share the lock forever. This prevents starvation of the writer.
  • Run interface media ioctl with shared netlock so packets can be processed while running ifconfig(8).
  • btrace(8) can be used to debug reference counting.
  • Use MP safe refcount for interface addresses.
  • Unlocked kbind(2).
  • Unlocked the pledge(2) system call.
  • Made UNIX domain sockets locking per-socket rather than coarse locking of the entire domain sockets layer.
• Direct Rendering Manager and graphics drivers
  • Updated drm(4) to Linux 5.15.69
  • inteldrm(4): support for Alder Lake, Raptor Lake
  • Reimplemented the TTM page allocation code using bus_dma(9) APIs to make sure DMA addresses are translated properly on architectures with an IOMMU. This fixed amdgpu(4) and radeondrm(4) on powerpc64, sparc64, and arm64 machines with SMMU.
  • Implemented support for framebuffers that don't start on a page boundary (like those on the 2021 14" and 16" MacBook Pro).
  • Added handling for framebuffers where the first pixel isn't page-aligned to wsfb(4).
  • Fixed Xorg(1) when using the luna88k 1bpp framebuffer hardware.
• VMM/VMD improvements
  • Improved error handling and logging in vmd(8)
  • Unify all internal structures and interfaces between vmd(8), vmctl(8) and vmm(4) to use bytes for memory and disk sizes.
  • Fix rebooting a received VM in vmd(8).
  • Have vmd(8) provide a copy of bios at 4g boundary. SeaBIOS and newer Linux kernels expect it there.
  • In vmd(8), fix off by one in VM memory range check.
  • In vmd(8), add support for MMIO assist. In vmm(4), send all port I/O emulation to userland.
  • Have vmd(8) compute i8254 read-back command latch from singular timestamp.
  • Improve the command line parsing in vmctl(8).
  • Let vmm(4) allow reading MSR_TSC on Intel hosts.
  • In vmm(4), reference count VMs and VCPUs.
  • In vmm(4), zero virtual addresses of VCPU state pages after freeing.
  • Fix `vmctl send` on Intel hosts by load the vmcs before reading VCPU registers in vmm(4).
  • Fix `vmctl receive` on Intel hosts by adding an additional fault type in vmm(4).
  • Add additional dt(4) tracepoints in various vmm(4) codepaths.
  • Add snmpd(8) AgentX support based around VM-MIB (RFC7666).
• Various new userland features:
  • Replaced rc.d(8) $rcexec variable with an rc_exec function. This will require a mechanical change from ${rcexec} to rc_exec in rc.d scripts. Kept compatibility to give people a chance to fix their custom scripts.
  • Introduced a new daemon_execdir variable to rc.d(8) for changing to a specified directory before running rc_exec.
  • Added ts(1), a timestamp utility.
  • Add a new configtest action to rc.d(8) and rcctl(8) to check configuration syntax of a daemon.
  • Added forest (-f) mode to ps(1).
• Various bugfixes and tweaks in userland:
  • Fixed openrsync(1) on sparc64 by eliminating a redundant second conversion of the int value from little to host endian.
  • Added connection timeout functionality to openrsync(1) via the --contimeout option.
  • Set the default openrsync(1) connection timeout that rpki-client(8) uses to 15 seconds.
  • Made use of the fact that repositories are unique objects in pkg_add(1) and annotated the quirks repository as cached, allowing for a large speed increase.
  • Enabled pkg_add(1) caching by default.
  • Changed the tied algorithm in pkg_add(1) to prevent O(n^2) behavior when packages contain several hundred copies of the same file.
  • Added a "processing" message for when pkg_add(1) is transferring data to inform the user that pkg_add is still working.
  • Added missing uuid_dec_le() to init_gp() so fdisk(8) -A works on big-endian architectures.
  • Aligned fdisk(8) logic with that used in the kernel to allow the protective EFI GPT partition to be in MBR partitions 0-3, not just 0.
  • Prevented use of "-u" when fdisk(8) is operating on GPT formatted disks.
  • Stopped telling fdisk(8) that macppc HAS_MBR.
  • Made fdisk(8) reject input of excessive length.
  • Fixed an fdisk(8) regression to allow editing an MBR of all zeroes.
  • Changed fdisk(8) to restrict user actions if neither GPT nor MBR structures can be found on the disk.
  • Made fdisk(8) print a warning when an MBR partition starts or extends past the end of the device.
  • Made fdisk(8) print a warning when a GPT partition start or end is outside the usable LBA area of the device.
  • Made fdisk(8) display "Microsoft basic data" instead of "FAT12" for GPT_UUID_MSDOS partitions.
  • Made fdisk(8) print GPT attributes in verbose output.
  • Made fdisk(8) use the correct GPT bootable attribute bit.
  • Made fdisk(8) not spoof GPT partitions with the attribute REQUIRED.
  • Made fdisk(8) ensure GPT headers, table entries and usable area don't overlap each other.
  • Removed disklabel(8) ability to edit disk geometry information.
  • Removed disklabel(8) and disktab(5) support for 'bs' (bootblock size) and 'sb' (superblock size) attributes.
  • Added keyword 'raid' to disklabel(8) template files, allowing auto-allocation of RAID partitions.
  • Removed disklabel(8) support for disktab(5) 'd[0-4]' (drive data) attributes.
  • Installed useful btrace(8) scripts in /usr/share/btrace.
  • Made btrace(8) execute the END probe upon receiving a SIGTERM signal.
  • Moved the wait for autoconf interfaces from rc(8) to netstart(8) to fix tunnel interfaces that depend on working autoconf interfaces.
  • Made netstart(8) create virtual interfaces up front if specified on the command line.
  • Changed rc.subr(8) to copy the message to stdout when using logger(1) to avoid needing to check syslog when running in debug mode.
  • Fixed kbd(8) so it doesn't fail silently when executed by a regular user.
  • In the sndio library, added the function sio_flush(3) to stop playback immediately. Altered sndiod(8) to wait until the buffer is drained before closing the device.
  • Made xterm(1) use a much safer FD-passing idiom for updating utmp(5).
  • Prevented a crash in vi(1) when cursor key support is disabled.
  • Updated vi(1) to apply expandtab to the output of a ! command.
  • Made mg(1) automatically delete trailing whitespace on RET in c-mode and auto-indent-mode.
  • Made grep(1) provide full context when using match count (-m)
  • Added the --null flag to grep(1) which makes grep print an ASCII NUL byte after the file name to make the output unambiguous.
  • Fixed multiple memory leaks in awk(1).
  • Changed compress(1) to print a more accurate message when -v is used with -k.
  • Fixed gzip(1) byte counts with 32-bit integers.
  • Fixed the growth check in compress(1) and gzip(1) in cases of small files or files with sufficiently random data.
  • Made timeout(1) -s accept HUP like kill(1) and GNU timeout(1) do.
  • Updated capitals and countries in the game quiz(6).
  • Set default sleep value of ico(1) to 10ms.
  • Fixed a bug in cron(8) where it could exit silently if ppoll(2) exited. Now it will log to syslog(3) instead of stderr.
  • Added llvm-profdata(1) to base so that ports can benefit from profiled builds.
  • Changed rc(8) to only attempt to set the yp(8) domainname if it has not been set yet.
  • Raised the "staff" login class data-size-cur on arm64 to be the same as that for amd64 in login.conf(5) (1536M).
  • Fixed patch(1) locate-hunk in empty files.
  • Fixed patch(1) in the case of reversing a patch that creates a file.
  • Added seconds to the uptime display of top(1).
  • Made putenv(3) return an error if the string starts with the '=' character. This matches the behavior on FreeBSD and NetBSD.
  • Fixed overflow of the number of errors in renice(8) by setting error instead of incrementing it.
  • Removed the "-c" compatibility option from vnconfig(8).
  • Stopped vnconfig(8) from printing the device name on failure.
  • Print a message when ld.so(1) fails inside execve(2) to clarify the failure mode when a dynamic executable is run while /usr isn't mounted.
  • Improved bioctl(8) RAID level parsing to check numeric levels before checking single character levels. This allows recognition of RAID 10 as a valid but unsupported level.
  • Fixed installboot(8) messaging when verbose (-v) and dry-run (-n) modes are combined with softraid(4).
  • Sped up wc(1) word counting.
• Improved hardware support and driver bugfixes, including:
  • New aplaudio(4) driver for Apple audio subsystem.

  • Added xhci(4) support for the dual role controllers integrated on the Qualcomm Snapdragon 8cx gen 3 SoC.
  • Added support for using the power button to wake up from suspend to axppmic(4).
  • Modified pms(4) to discard relative movement packets outside of the [-127, 127] range to prevent cursor jumps when using the trackpoint on some Lenovo laptops.
  • Allowed spdmem(4) to attach to gdiumiic(4).
  • Make spdmem(4) attach on 2F-based loongson systems.
  • Added power button support to aplsmc(4).
  • Changed the mfii(4) RAID controller driver to allow the firmware more time to transition out of the UNDEFINED state.
  • Added Wacom One S (CTL-472) support to uwacom(4).
• New or improved network hardware support:
  • Increased rx buffer size on uaq(4) to 62kB.
  • Repaired rge(4) hardware VLAN tagging.
  • Provide statistics via kstats for mvneta(4).
  • Enabled aq(4) on arm64.
  • Implemented and enabled IPv4, TCP, and UDP checksum offloading for igc(4).
  • Fixed a panic triggered by ifconfig bnxt0 down by changing bnxt(4) devices to not run rx and tx interrupt handlers when the interface is not running.
  • Introduced Large Receive Offloading of TCP segment offloading in ix(4). Also added a tso option to ifconfig(8) to enable and disable this feature.
• Added or improved wireless network drivers:
  • Made device matching in iwx(4) more similar to Linux iwlwifi in order to recognize more devices.
  • Added support for AX210/AX211 devices to iwx(4).
  • Fixed iwx(4) setting of HT/VHT bits in rate flags of the Tx command that could cause a firmware panic.
  • Added handling of 9k devices which do not support antenna B to iwm(4).
  • Fixed bwfm(4) ifconfig media display on devices with sta_info command version 3.
  • Fixed a bwfm(4) crash during USB detach.
  • Fixed detection of the Rx data rate on rtl8192eu urtwn(4) devices.
  • Fixed integer overflows in the iwm(4) and iwx(4) firmware file parsers.
• IEEE 802.11 wireless stack improvements and bugfixes:
  • Make sure drivers initialize all of ieee80211_rxinfo struct.
• Installer, upgrade and bootloader improvements:
  • Fixed the watchdog in the installer so that it is reset after each download and each set installation.
  • Ensured that running sysupgrade(8) on -stable will move to the next release, not -current.
  • Added the -b option to sysupgrade(8) to set an alternative base directory to which the installation files will be downloaded.
  • Increased the disklabel(8) auto partitioner's maximum size for /usr to 30G.
  • Altered installer behavior so the vlan(4) question won't be asked unless another network interface exists.
  • Added support for wildcards in fw_update(8) patterns.
  • Added support for booting from RAID 1C softraid(4) volumes on amd64, sparc64 and arm64.
  • Added NFS client support to the luna88k RAMDISK kernel.
  • Made the EFI bootloader provide the extra parameters necessary to use non-standard UARTs on the AMD Ryzen Embedded V1000 SoCs as console.
  • Switched bootloaders to the extended BOOTARG_CONSDEV struct.
  • Added UFS2 support to landisk boot blocks.
  • Removed "force CHS" capability from biosboot(8)
• Security improvements:
  • Implemented privilege separation in xlock(1).
  • Added privilege separation to snmpd(8).
  • The TZ environment variable no longer supports absolute paths, to fit better into the pledge(2) bypass model.
  • AF_UNIX socket bind(2) and connect(2) now follow unveil(2) configuration.
  • New ypconnect(2) system call creates a socket based upon the IP address encoded directly in a locked ypbinding file, thereby removing a horrible hack to support YP lookups in programs using strong pledge(2) rules.
  • Processes that pledge("vminfo") may now use the read-only swapctl(2) operations SWAP_NSWAP and SWAP_STATS providing information on swap devices.
  • Randomized the rekey interval of arc4random(3).
  • Reduce the attack surface by introducing a 'local bind' mode to ypldap(8). In this mode ypldap binds its RPC sockets to loopback, so YP services are only available to the host it's running on. ypldap writes the YP binding file in /var/yp/binding itself and replaces ypbind(8) and ypserv(8). This also implies that portmap(8) doesn't need to be running anymore when local bind mode is used.
  • Changed the /sbin daemons dhcpleased(8), mountd(8), nfsd(8), pflogd(8), resolvd(8), slaacd(8), and unwind(8) to be dynamically linked to allow them to benefit from all the additional mitigations that dynamically linked executables gain. NFS mounting of /usr must now use statically configured IP addresses.
• Changes in the network stack:
  • Added the recvmmsg(2) system call that allows receiving multiple msghdrs at once, and the sendmmsg syscall that allows sending multiple msghdrs at once.
  • Relaxed address availability check for multicast(4) binds so processes listening for the same multicast address do not need to be the same UID.
  • Introduced dedicated link entries for snapshots to pfsync(4).
  • Changed pf(4) handling of IGMP and ICMP6 MLD packets to allow multicast control packets to work by default.
  • Made pf(4) more paranoid about IGMP/MLD messages.
  • Fixed a logic bug in pf_find_state() that could cause pf(4) to incorrectly block a packet.
  • Fixed pf(4) syncookies during fast TCP port reuse.
  • Fixed a bug in pf(4) where a pool defined like "172.16.0.0/16" would count as a pool size of one address. Also fixed random selection of source address to be uniform across the whole pool.
  • Fixed a kernel panic in pf(4) if IP options with an ICMP payload were truncated. Such packets will now be dropped instead.
  • Allow forwarding to and from IPs in the 240/4 range.
  • Corrected the Virtual Ethernet Bridge veb(4) to avoid calling if_enqueue from an smr critical section.
  • Reworked the kroute rttimer code to fix icmp_pmtu_timeout crashes.
  • Fixed an interrupt storm upon suspend on Amlogic arm64 boards.
  • Fixed a race between pflow_output_process() and pflow_clone_destroy() in pflow(4).
  • Added a missing input validation step to pipex(4) MPPE keylenbits.
• Routing daemons and other userland network improvements:
  • IPsec support was improved:
    • Made iked(8) ignore any CERT payload after the first rather than failing the exchange when more than one CERT payload is received.
    • Added iked(8) support for sending certificate chains with intermediate CAs in multiple CERT payloads.
    • Added an OpenIKED Vendor ID payload in the iked(8) initial handshake to make it easier to handle interoperability problems with older versions in the future.
    • Added iked(8) connection statistics for successful and failed connections, error types, and other events that can be printed with "ikectl show stats".
  • In bgpd(8),
    • Implement max-communities filter to limit the number of allowed communities, ext-communities and large-communities.
    • Fix insertion of additional non-transitive extended communities when sending out prefixes.
    • Relax IP address limitation by allowing prefixes in 240/4.
    • Implement RFC 9234 - Route Leak Prevention and Detection Using Roles in UPDATE and OPEN Messages.
    • Full support for RFC 7911 - Advertisement of Multiple Paths in BGP (ADD-PATH).
    • Improve FIB code, handle IPv6 scoped addresses properly.
    • Add bgplgd(8), a FastCGI server providing a REST API to execute bgpctl(8) commands.
    • Bugfix: bgpd(8) could fail to invalidate nexthops and incorrectly leave them in the FIB or Adj-RIB-Out.
    • Speedup bgpctl show rib 10/8 or-longer and show rib 10/8 or-shorter
    • Switch various static hash tables to RB trees improving performance on large systems
    • Export per neighbor pending update and withdraw statistics
    • Fix race between a neighbor session reset and its update message backlog
    • Improve handling of nexthop reachability state changes
    • Made sure only one bgpd(8) roa softreconfig runner is run at any time.
  • rpki-client(8) saw some changes:
    • Allowed more than one CRL URI in certificates.
    • Do not apply timezone offsets when converting X509 times. X509 times are in UTC and comparing them to times in different timezones would cause validity problems.
    • Add support for an operator-configurable skiplist facility. Operators can specify a list of FQDNs which should not be contacted when synchronizing the local cache to the network.
    • Emit a warning when a RRDP session serial number decreases.
    • DER decoding functions were refactored to leverage ASN.1 templates.
    • Add support to validate & inspect .sig files containing RPKI Signed Checklists in filemode (-f). (draft-ietf-sidrops-rpki-rsc-08)
    • Print various statistics after the completion of the main process.
    • Add support to decode & print TAL (RFC 8630) details in filemode (-f).
    • Emit objects in Concatenated JSON format when filemode (-f) and the JSON output flag (-j) are combined.
    • Add support for validating Autonomous System Provider Authorization (ASPA) objects conforming to draft-ietf-sidrops-aspa-profile-10. Validated ASPA payloads are visible in JSON and filemode (-f) output.
    • Set rsync(1) connection I/O idle timeout to 15 seconds.
    • Unify the maximum idle I/O and connect timeouts for rsync(1) & HTTPS.
    • rpki-client(8) now performs stricter EE certificate validation:
      • Disallow AS Resources extensions in ROA EE certificates.
      • Disallow Subject Information Access (SIA) extensions in RPKI Signed Checklist (RSC) EE certs.
      • Check the resources in ROAs and RSCs against EE certs.
    • Improve readability and add various information being printed in verbose mode.
    • Extend filemode (-f) output and print X.509 certificates in PEM format when increased verbosity (-vv) is specified.
    • Shorten the RRDP I/O idle timeout.
    • Introduce a deadline timer that aborts all repository synchronization after seven eights of timeout (-s). With this rpki-client has improved chances to complete and produce an output even when a CA is excessively slow.
    • Abort a currently running RRDP request process when the per-repository timeout is reached.
    • Permit multiple AccessDescription entries in SIA X.509 extensions. While fetching from secondary locations is not yet supported, rpki-client will not treat occurrence as a fatal error.
    • Resolve a potential for a race condition in non-atomic RRDP deltas.
    • Fix some memory leaks.
    • Improve compliance with the HTTP protocol specification.
  • In snmpd(8),
    • Allow object names to be used in addition to OIDs in snmpd.conf(5).
    • Better type hinting for debug logging.
    • Introduce a blocklist feature, which removes subtrees from view.
    • Reintroduce AgentX master support.
    • Move non-SNMP related metrics to their own AgentX based backend.
    • The snmpe process is now pledged stdio recvfd inet unix.
    • Imported snmpd_metrics(8). This allows those who need to use net-snmpd the ability to access base snmpd(8) metrics.
  • In ldapd(8), match password schemas case sensitive.
  • In ospfd(8), relax the limitations on what is an acceptable unicast IP. There are no more experiments in IPv4 and so there is less reason for network daemons to deny formerly experimental IP space. Multicast IPs (224/4) and loopback (127/8) are still disallowed.
  • Added check to acme-client(1) to ensure the challenge token is turned into a filename that is base64url encoded.
  • Added RFC 9234 "BGP Role" support to tcpdump(8)
  • Have tcpdump(8) print ASnumbers in 'asplain' format instead of the old 'asdot' format.
  • Fixed a crash in libpcap when it would walk off the end of the array performing frees.
  • Made -X connect SOCKS work with IPv6 addresses in nc(1).
  • Introduced a blocklist backend and keyword to snmpd(8), this deprecates filter-pf-addresses.
  • Changed dhclient(8) to defer to dhcpleased(8) by doing execve ifconfig and providing syslog warnings about deprecated options.
  • Implemented dig(1) support for SVCB and HTTPS record types.
  • Made resolvd(8) write /etc/resolv.conf in a more atomic manner.
  • Added a slowcgi(8) -t flag to change the request timeout.
  • Corrected handling of an abnormal FastCGI termination in httpd(8).
  • Made newer MIME type definitions take precedence over existing ones in httpd(8).
  • Moved the relayd(8) daemon(3) call to just before forking the children so the parent disassociates from its controlling terminal and shell, but not from its children.
  • Changed ftp(1) to use non-blocking connect(2) with ppoll(2) and timeout instead of alarm(3). This allows failing over to another IP address for hosts that have more than one.
• tmux(1) improvements and bug fixes:
  • Added an ACL list for multiple users attaching to the tmux(1) socket.
  • Ensured cursor remains on selected item on menu.
  • Added support for OSC 8 hyperlinks.
  • Added support for hyperlinks with capture-pane -e and a mouse_hyperlink format.
  • Added an "all" state to allow-passthrough to work even in invisible panes.
  • Fixed a crash when searching for .* with extremely long lines.
  • Added vi(1) Home/End bindings.
  • Added a Nobr terminfo capability to tell tmux(1) the terminal does not use bright colors for bold.
  • Added a notification when a paste buffer is deleted.
  • Fixed window size reporting.
• LibreSSL version 3.6.0
  • New features
    • EVP API for HKDF ported from OpenSSL and subsequently cleaned up.
    • The security level API (SSL_{,CTX}_{get,set}_security_level()) is now available. Callbacks and ex_data are not supported. Sane software will not be using this.
    • Experimental support for the BoringSSL QUIC API.
    • Add initial support for TS ESSCertIDv2 verification.
    • LibreSSL now uses the Baillie-PSW primality test instead of Miller-Rabin.
  • Compatibility changes
    • The ASN.1 time parser has been refactored and rewritten using CBS. It has been made stricter in that it now enforces the rules from RFC 5280.

    • Error check tls_session_secret_cb() like OpenSSL.
    • Added ASN1_INTEGER_{get,set}_{u,}int64()
    • Move leaf certificate checks to the last thing after chain validation.
    • Added -s option to openssl(1) ciphers that only shows the ciphers supported by the specified protocol.

• OpenSSH 9.1
  • Security
    • ssh-keyscan(1): fix a one-byte overflow in SSH banner processing
    • ssh-keygen(1): fix double free() in error path of signing/verify code
    • ssh-keysign(8): fix double-free in error path introduced in OpenSSH 8.9.
  • Potentially-incompatible changes
    • ssh(1), sshd(8): SetEnv directives in ssh_config and sshd_config are now first-match-wins to match other directives. Previously if an environment variable was multiply specified the last set value would have been used.
    • ssh-keygen(8): ssh-keygen -A (generate all default host key types) will no longer generate DSA keys, as these are insecure and have not been used by default for some years.
    • ssh(1), sshd(8): add a RequiredRSASize directive to set a minimum RSA key length. Keys below this length will be ignored for user authentication and for host authentication in sshd(8).
      ssh(1) will terminate a connection if the server offers an RSA key that falls below this limit, as the SSH protocol does not include the ability to retry a failed key exchange
    • sftp-server(8): add a [email protected] extension request that allows the client to obtain user/group names that correspond to a set of uids/gids.
    • sftp(1): use [email protected] sftp-server extension (when available) to fill in user/group names for directory listings.
    • sftp-server(8): support the home-directory extension request defined in draft-ietf-secsh-filexfer-extensions-00. This overlaps a bit with the existing "[email protected]", but some other clients support it.
    • ssh-keygen(1), sshd(8): allow certificate validity intervals, sshsig verification times and authorized_keys expiry-time options to accept dates in the UTC time zone in addition to the default of interpreting them in the system time zone. YYYYMMDD and YYMMDDHHMM[SS] dates/times will be interpreted as UTC if suffixed with a 'Z' character.
      Also allow certificate validity intervals to be specified in raw seconds-since-epoch as hex value, e.g. -V 0x1234:0x4567890. This is intended for use by regress tests and other tools that call ssh-keygen as part of a CA workflow.
    • sftp(1): allow arguments to the sftp -D option, e.g. sftp -D /usr/libexec/sftp-server -el debug3.
    • ssh-keygen(1): allow the existing -U (use agent) flag to work with -Y sign operations, where it will be interpreted to require that the private keys is hosted in an agent.
  • Bugfixes
    • ssh-keygen(1): implement the "verify-required" certificate option. This was already documented when support for user-verified FIDO keys was added, but the ssh-keygen(1) code was missing.
    • ssh-agent(1): hook up the restrict_websafe command-line flag; previously the flag was accepted but never actually used.
    • sftp(1): improve filename tab completions: never try to complete names to non-existent commands, and better match the completion type (local or remote filename) against the argument position being completed.
    • ssh-keygen(1), ssh(1), ssh-agent(1): several fixes to FIDO key handling, especially relating to keys that request user-verification. These should reduce the number of unnecessary PIN prompts for keys that support intrinsic user verification.
    • ssh-keygen(1): when enrolling a FIDO resident key, check if a credential with matching application and user ID strings already exists and, if so, prompt the user for confirmation before overwriting the credential.
    • sshd(8): improve logging of errors when opening authorized_keys files.
    • ssh(1): avoid multiplexing operations that could cause SIGPIPE from causing the client to exit early. bz3454
    • ssh_config(5), sshd_config(5): clarify that the RekeyLimit directive applies to both transmitted and received data.
    • ssh-keygen(1): avoid double fclose() in error path.
    • sshd(8): log an error if pipe() fails while accepting a connection.
    • ssh(1), ssh-keygen(1): fix possible NULL deref when built without FIDO support.
    • ssh-keyscan(1): add missing *-sk types to ssh-keyscan manpage.
    • sshd(8): ensure that authentication passwords are cleared from memory in error paths.
    • ssh(1), ssh-agent(1): avoid possibility of notifier code executing kill(-1).
    • ssh_config(5): note that the ProxyJump directive also accepts the same tokens as ProxyCommand.
    • scp(1): do not ftruncate(3) files early when in sftp mode. The previous behaviour of unconditionally truncating the destination file would cause scp ~/foo localhost: and scp localhost:foo ~/ to delete all the contents of their destination.
    • ssh-keygen(1): improve error message when ssh-keygen -Y sign is unable to load a private key.
    • sftp(1), scp(1): when performing operations that glob(3) a remote path, ensure that the implicit working directory used to construct that path escapes glob(3) characters. This prevents glob characters from being processed in places they shouldn't, e.g. cd /tmp/a*/, get *.txt should have the get operation treat the path /tmp/a* literally and not attempt to expand it.
    • ssh(1), sshd(8): be stricter in which characters will be accepted in specifying a mask length; allow only 0-9.
    • ssh-keygen(1): avoid printing hash algorithm twice when dumping a KRL.
    • ssh(1), sshd(8): continue running local I/O for open channels during SSH transport rekeying. This should make ~-escapes work in the client (e.g. to exit) if the connection happened to have stalled during a rekey event.
    • ssh(1), sshd(8): avoid potential poll() spin during rekeying
    • Further hardening for sshbuf internals: disallow "reparenting" a hierarchical sshbuf and zero the entire buffer if reallocation fails.
• mandoc 1.14.6 plus some new features and many bugfixes, including:
  • Significantly improved accessibility of mandoc(1) -T html and man.cgi(8) output by using semantically better HTML elements in several places and by adding ARIA and DPUB-ARIA roles and aria-label attributes to several HTML elements.
  • Got rid of archaic HTML table markup for header and footer lines in favor of flexbox CSS. Rendering now adapts to browser windows of arbitrary narrowness.
  • Prevented -T html output from turning breakable hyphens into underscores in URI fragment identifiers.
  • Improved the roff(7) escape sequence parser in several fundamental ways regarding output correctness and groff compatibility.
  • Corrected output that depends on the order of evaluation of roff(7) escape sequences by parsing them left-to-right rather than right-to-left.
  • Significantly improved -T lint diagnostics regarding syntax errors in roff(7) escape sequences and in their arguments.
  • Stopped emitting vertical space before the tbl(7) .TS (table start) macro for compatibility with the same change in groff. This implies .PP or .Pp macros may need to be inserted before .TS in some (but not all!) places in some manual pages using tbl(7).
  • Stopped skipping vertical space after the tbl(7) .TE (table end) macro of boxed tables for compatibility with the same change in groff. This implies .sp requests may need to be removed after .TE in some manual pages using tbl(7).
  • Corrected the calculation of the width of spanned tbl(7) columns.
  • Improved the handling of literal tab characters in filled text in multiple ways for compatibility with groff and Heirloom troff.
  • Plus bugfixes for two segfaults, two infinite loops, and several assertion failures.

Quick installer information for people familiar with OpenBSD, and the use of the "disklabel -E" command. If you are at all confused when installing OpenBSD, read the relevant INSTALL.* file as listed above!

OpenBSD/alpha:

If your machine can boot from CD, you can write install72.iso or cd72.iso to a CD and boot from it. Refer to INSTALL.alpha for more details.

OpenBSD/amd64:

If your machine can boot from CD, you can write install72.iso or cd72.iso to a CD and boot from it. You may need to adjust your BIOS options first.

If your machine can boot from USB, you can write install72.img or miniroot72.img to a USB stick and boot from it.

If you can't boot from a CD, floppy disk, or USB, you can install across the network using PXE as described in the included INSTALL.amd64 document.

If you are planning to dual boot OpenBSD with another OS, you will need to read INSTALL.amd64.

OpenBSD/arm64:

Write install72.img or miniroot72.img to a disk and boot from it after connecting to the serial console. Refer to INSTALL.arm64 for more details.

OpenBSD/armv7:

Write a system specific miniroot to an SD card and boot from it after connecting to the serial console. Refer to INSTALL.armv7 for more details.

OpenBSD/hppa:

Boot over the network by following the instructions in INSTALL.hppa or the hppa platform page.

OpenBSD/i386:

If your machine can boot from CD, you can write install72.iso or cd72.iso to a CD and boot from it. You may need to adjust your BIOS options first.

If your machine can boot from USB, you can write install72.img or miniroot72.img to a USB stick and boot from it.

If you can't boot from a CD, floppy disk, or USB, you can install across the network using PXE as described in the included INSTALL.i386 document.

If you are planning on dual booting OpenBSD with another OS, you will need to read INSTALL.i386.

OpenBSD/landisk:

Write miniroot72.img to the start of the CF or disk, and boot normally.

OpenBSD/loongson:

Write miniroot72.img to a USB stick and boot bsd.rd from it or boot bsd.rd via tftp. Refer to the instructions in INSTALL.loongson for more details.

OpenBSD/luna88k:

Copy 'boot' and 'bsd.rd' to a Mach or UniOS partition, and boot the bootloader from the PROM, and then bsd.rd from the bootloader. Refer to the instructions in INSTALL.luna88k for more details.

OpenBSD/macppc:

Burn the image from a mirror site to a CDROM, and power on your machine while holding down the C key until the display turns on and shows OpenBSD/macppc boot.

Alternatively, at the Open Firmware prompt, enter boot cd:,ofwboot /7.2/macppc/bsd.rd

OpenBSD/octeon:

After connecting a serial port, boot bsd.rd over the network via DHCP/tftp. Refer to the instructions in INSTALL.octeon for more details.

OpenBSD/powerpc64:

To install, write install72.img or miniroot72.img to a USB stick, plug it into the machine and choose the OpenBSD install menu item in Petitboot. Refer to the instructions in INSTALL.powerpc64 for more details.

OpenBSD/riscv64:

To install, write install72.img or miniroot72.img to a USB stick, and boot with that drive plugged in. Make sure you also have the microSD card plugged in that shipped with the HiFive Unmatched board. Refer to the instructions in INSTALL.riscv64 for more details.

OpenBSD/sparc64:

Burn the image from a mirror site to a CDROM, boot from it, and type boot cdrom.

If this doesn't work, or if you don't have a CDROM drive, you can write floppy72.img or floppyB72.img (depending on your machine) to a floppy and boot it with boot floppy. Refer to INSTALL.sparc64 for details.

Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install will most likely fail.

You can also write miniroot72.img to the swap partition on the disk and boot with boot disk:b.

If nothing works, you can boot over the network as described in INSTALL.sparc64.

How to upgrade

If you already have an OpenBSD 7.1 system, and do not want to reinstall, upgrade instructions and advice can be found in the Upgrade Guide.

Notes about the source code

src.tar.gz contains a source archive starting at /usr/src. This file contains everything you need except for the kernel sources, which are in a separate archive. To extract:

# mkdir -p /usr/src
# cd /usr/src
# tar xvfz /tmp/src.tar.gz

sys.tar.gz contains a source archive starting at /usr/src/sys. This file contains all the kernel sources you need to rebuild kernels. To extract:

# mkdir -p /usr/src/sys
# cd /usr/src
# tar xvfz /tmp/sys.tar.gz

Both of these trees are a regular CVS checkout. Using these trees it is possible to get a head-start on using the anoncvs servers as described here. Using these files results in a much faster initial CVS update than you could expect from a fresh checkout of the full OpenBSD source tree.

Ports Tree

A ports tree archive is also provided. To extract:

# cd /usr
# tar xvfz /tmp/ports.tar.gz

Go read the ports page if you know nothing about ports at this point. This text is not a manual of how to use ports. Rather, it is a set of notes meant to kickstart the user on the OpenBSD ports system.

The ports/ directory represents a CVS checkout of our ports. As with our complete source tree, our ports tree is available via AnonCVS. So, in order to keep up to date with the -stable branch, you must make the ports/ tree available on a read-write medium and update the tree with a command like:

# cd /usr/ports
# cvs -d [email protected]:/cvs update -Pd -rOPENBSD_7_2

[Of course, you must replace the server name here with a nearby anoncvs server.]

Note that most ports are available as packages on our mirrors. Updated ports for the 7.2 release will be made available if problems arise.

If you're interested in seeing a port added, would like to help out, or just would like to know more, the mailing list [email protected] is a good place to know.
