OpenBSD 6.7 released - May 19, 2020

- OpenBSD 6.7 RELEASED -------------------------------------------------

May 19, 2020.

We are pleased to announce the official release of OpenBSD 6.7.
This is our 48th release.  We remain proud of OpenBSD's record of more
than twenty years with only two remote holes in the default install.

As in our previous releases, 6.7 provides significant improvements,
including new features, in nearly all areas of the system:

 - General improvements and bugfixes:
    o Reduced the minimum allowed number of chunks in a CONCAT volume
      from 2 to 1, increasing the number of volumes which can be created
      on a single disk with bioctl(8) from 7 to 15. This can be used to
      create more partitions than previously.
    o Rewrote the cron(8) flag-parsing code to be getopt-like, allowing
      tight formations like -ns and flag repetition. Renamed the
      "options" field in crontab(5) to "flags".
    o Added crontab(5) -s flag to the command field, indicating that
      only a single instance of the job should run concurrently.
    o Added cron(8) support for random time values using the ~ operator.
    o Allowed cwm(1) configuration of window size based on percentage of
      the master window during horizontal and vertical tiling actions.
    o Allowed use of window-htile and window-vtile with the "empty"
      group clients in cwm(1).
    o Switched powerpc to a machine-independent mplock implementation,
      allowing use of witness(4).
    o Added acpi(4) support for the _CCA method, indicating whether DMA
      is cache-coherent.
    o Switched the default compiler on powerpc to clang.
    o Bumped nvme(4) max physio() i/o size to 128K.
    o Improved apmd(8) support for automatic suspend/hibernate (-z/-Z).
      The daemon now reacts to power changes messages sent by the
      battery driver. Those messages are ignored for 60 seconds after a
      resume, so that the user can take control before the machine goes
      back to sleep.
    o Prevented a kernel hang when no unlocked ffs_softdep worklist
      items could be processed.
    o Stopped counting pages mapped as PROT_NONE against the RLIMIT_DATA
      limit, helping code which reserves large chunks of address space
      but populates it sparsely.
    o Added the $REQUEST_SCHEME variable to httpd.conf(5), allowing
      preservation of the original connection type (http or https) for
      redirect locations
    o Implemented "strip" option in httpd.conf(5) for fastcgi to be able
      to have multiple chroots under /var/www for FastCGI servers.
    o Changed httpd(8) to send a 408 response when a timeout happens
      while headers are being received, but close the connection if no
      request is received.
    o Updated en_US.UTF-8.src to Unicode 12.1.
    o Added a new __tmpfd system call which creates a new, unnamed file
      in /tmp, intended for shm/fd passing, but in programs that may
      otherwise lack filesystem access (due to restrictions imposed by
      unveil(2) or pledge(2)).
    o Imported dt(4), a driver and framework for Dynamic Profiling, and
      an accompanying bug tracer that speaks the bt(5) language.
    o Added a human-readable mode (-h) to systat(1).
    o Implemented scrolling in top(1) using the 9 and 0 keys.
    o Added timeout_set_flags(9) and TIMEOUT_INITIALIZER_FLAGS(9) to the
      timeout API, allowing the caller to initialize timeouts with
      arbitrary flags.
    o Introduced TIMEOUT_SCHEDULED flag and tos_scheduled statistic to
    o Switched to tickless backend in timeout(9), adding new interface
      timeout_at_ts(9) to avoid backwardly compatible behavior.
    o Added the system clock interface nanoboottime(9), returning the
      UTC time at which the system booted in seconds and nanoseconds.
    o Introduced efficient page freeing in reverse order from uvm,
      greatly improving cases of massive page freeing.
    o Added uvm_objfree to uvm to efficiently free all pages from a uvm
      object, used in the buffer cache for considerable speedup when
      freeing pages.
    o Modified buffer cache to use individual uvm_objs per buffer to
      speed page lookups.
    o Speed up sort(1) by not performing a top-level sort when -c is
      used with a -k field.
    o Modified -z mode verification in signify(1) to save the header and
      output it, so signify -zV >saved.tgz will keep the signature for
      later checks.
    o Enabled DNSSEC validation in unbound(8) by default.
    o ntpd(8) now does constraint validation against and
      2620:fe::fe by default.
    o Fixed arp(4) issues created by dhclient(8) modifying existing
    o Fixed route.conf(5) handling by dhclient(8) when an interface
      loses link.
    o Restored previous dhclient(8) behaviour of rejecting leases that
      lack a subnet mask.
    o Enabled dhclient(8) to configure carp(4) interfaces.
    o Fixed dhclient(8) releasing leases without a server identifier.
    o Improved dhclient(8) NAK handling in various corner cases.
    o Fixed dhclient(8) endlessly sending REQUEST messages when an ACK
      is never received.
    o Prevented dhcpd(8) from referencing freed memory when releasing a
      lease with an unusually long uid.
    o Corrected parsing of classless static default route "0/0" in
    o Increased to 15 the number of softraid(4) CONCAT volumes that can
      be created on a single disk.
    o Fixed softraid(4) CRYPTO volumes on 4K-sector disks.

 - The FFS2 filesystem, which uses 64bit timestamps and block numbers is
       now the default for new installs on nearly all architectures:
    o Enabled ffs2 in sgi bootblocks and ramdisks.
    o Made ffs2 the default filesystem type on installs except for
      landisk, luna88k and sgi.
    o Changed the sparc64 bootblocks to be able to read from ffs1, ffs2
      and softraid, and enabled the ffs2 option for both floppies.
    o Enabled FFS2 on the landisk ramdisk.
    o Taught i386 boot(8), cdboot(8) and pxeboot(8) about ffs2.
    o Taught macppc boot(8) about ffs2.
    o Taught sparc64 boot(8) about ffs2.
    o Allowed hppa boot(8) to read from an ffs2 filesystem.
    o Allowed alpha boot(8) to read from an ffs2 filesystem and adapted
      its custom installboot to deal with ffs2. Also fixed the partition
      read code to deal with offsets greater than 2G.
    o Adapted biosboot(8) so that it can read boot(8) from an ffs2
    o Allowed amd64 boot(8) to read from an ffs2 filesystem. Enabled
      ffs2 for floppy.
    o Allowed loongson boot(8) to read from an ffs2 filesystem.
    o Allowed arm64 and armv7 efiboot(8) to read from an ffs2

      dup2(2), dup3(2), flock(2), fcntl(2), kqueue(2), pipe(2), pipe2(2)
      and nanosleep(2) are run without KERNEL_LOCK.
    o The generic part of ioctl(2) is run without KERNEL_LOCK.
    o Reworked AMD smt/core/package detection, helping prevent cores
      being misidentified as threads.

      interface is marked up. This behavior must now be explicitly
      enabled with ifconfig(8) join "".
    o A background scan is now triggered when root runs the ifconfig(8)
      scan command. This updates the list of cached APs displayed by the
      scan command and forces a search for a better AP to roam to.
    o Add nwflag nomimo which can be set with ifconfig(8) to work around
      packet loss in 11n mode if the wireless network device has unused
      antenna connectors.
    o Increased the net80211 node cache size to allow more APs to be
      viewed during scans.

      background scan in 11n mode.
    o Made background scans less frequent if they keep choosing the same
    o Fix kernel crashes in net80211 hostap mode due to mbuf corruption
      which occurred if a relatively long SSID was configured.

      mechanism under moderate load.
    o Improved error handling for bwfm(4) connection attempts.
    o Improved automatic switching between wifi networks by lowering the
      priority of networks in the ifconfig(8) join list which fail to
    o Avoid repeated switching between APs in areas where APs are tuned
      for low transmit range.
    o Raised net80211's "beacon miss" threshold to avoid frequent
      reconnects under conditions which cause loss of beacons.
    o Reduced stalls on packet loss in 11n mode by improving net80211
      handling of the Rx block ack sequence number window and queue.
    o Fixed a bug where outstanding frames on the iwn(4) aggregation
      queue interfered with roaming to another AP.
    o Fixed a race condition in iwm(4) Rx interrupt handling.
    o Implemented a workaround for missing Tx completion interrupts in
      iwm(4) which could lead to failures when roaming to another AP.
    o Re-enabled firmware-based Tx retries at lower rates for iwm(4),
      reducing packet loss.
    o Fixed automatic Tx rate control issues in iwn(4), and iwm(4).
    o Fixed a use-after-free that caused a kernel crash during zyd(4)
      device detach.

    o Fixed a panic when using pppac(4) without pipex(4).
    o Fixed a "route contains no arp information" bug where a kernel
      routing table entry was incorrectly deleted upon insertion of a
      new entry.
    o Stopped processing packets under non-exclusive netlock, preventing
      concurrency in the socket layer.
    o Prevented data corruption on UDP receive socket buffers by
      grabbing the exclusive NET_LOCK() in the softnet thread.
    o Fixed a kernel crash due to unlimited recursion caused by local
      outbound UDP broadcast/multicast packets sent by a spliced socket.
    o Added IPv6 support to umb(4).
    o Added support for very old firmware umsm devices with umsm(4)
      rather than umb(4).
    o Added pppac(4) code for a dedicated PPP Access Concentrator
      interface and switched npppd.conf(5) to use pppac(4) instead of
    o Added a check when IP forwarding is disabled to ensure packet
      destination address matches interface address.
    o Fixed kernel crash in pf_ioctl with WITH_PF_LOCK and NET_TASKQ >
    o Ensured proper kernel stack alignment on mips64, fixing a panic on
      octeon related to pppoe(4).
    o Added rge(4), a new driver for Realtek 8125 PCI Express 2.5Gb
      ethernet devices.
    o Repaired the "set delay" option for pf(4) to function as specified
      in pf.conf(5).
    o Prevented non-root users from using ioctl(2) to alter the address
      of a network interface.
    o Prevented non-root users from setting the parameters of pppoe(4)
    o Removed mobileip(4).
    o Stopped checking whether the IPv6 source address of a neighbor
      advertisement is from a neighbor's address, not required in
      accordance with RFC 4861.

 - Installer improvements:
    o Simplified sysupgrade(8) directory check and creation
      (/home/_syspatch). It can now be a symlink.
    o Printed the URL when sysupgrade(8) fetches new sets.
    o Added an opportunistic run of fw_update(1) to sysupgrade(8) before
      rebooting to run the upgrade.

 - Security improvements:
    o unveil(2) is now used in 82 userland programs to redact filesystem
    o Used unveil(2) to reduce filesystem access in vmstat(8), iostat(8)
      and systat(1).
    o Extracted dig(1), host(1) and nslookup(1) from the bind(8) source
      code and cleaned up the source code by removing not needed
      features and auditing it. The kernel API accessible to these
      programs is now restricted through pledge(2).
    o System calls may now only be performed from selected code regions:
      the main program,, and the signal trampoline. A
      new system call msyscall(2) indicates the libc range, and
      activates the locking. This change hardens against some attack
    o Prevented stack trace saving from inspecting untrusted data on
      amd64, arm64 and i386.
    o Used lfence in place of stac/clac on pre-SMAP CPUs to protect
      against Load-Value-Injection attacks against the kernel.
    o Prevented a panic due to missing sysctl(2) input validation.
    o Injected failure to fetch entropy with an rdrand() timeout as an
      entropic event, along with an additional rdtsc measuring the
      vmexit latency.
    o Enforced that ksh(1) TMOUT is an integer literal to prevent
      command execution from the environment at shell initialization
    o Ensured the first 2MB page of the amd64 kernel is correctly mapped
      read-only in the direct map.
    o Addressed an armv7/arm64 speculative execution issue by changing
      the system call ABI to skip two instructions and inserting a
      barrier after each system call.

       - Fixed insufficient username validation performed by libc's
         authentication privilege separation layer and added
         additional validation points, further validating in login(1)
         and su(1).
       - Prevented escalation to the auth group in xlock(1) through
         path-related environment variables and disabled mesa and
         opengl functionality.

 - Routing daemons and other userland network improvements:
    o Add initial support for JSON output in bgpctl(8).
    o Allow setting both IPv4 and IPv6 local-addresses at the same time
      in bgpd.conf(5) group blocks. Introduced no local-address to reset
      a previously set local address.
    o Properly aggregate duplicate bgpd(8) roa table prefix/source-as
      combinations into a single entry with the longest maxlen length.
    o Implemented bgpd.conf(5) max-prefix NUM out to limit the number of
      announced prefixes, avoiding leaks of full tables to upstreams and
    o Extended bgpctl(8) show neighbor to include the received and set
      prefix count, as well as the max-prefix out limit if set.
    o Improved reporting of notifications to include the suberror cause.
    o Also report the last received error cause in bgpctl(8) show
      neighbor output.
    o Fix softreconfig out handling to also work for neighbors using

    o Fixed empty response packages sent out by ripd(8) when entries are
      skipped due to split-horizon simple.
    o Reduced temporary address valid lifetime to 2 days in slaacd(8).
    o Made slaacd(8) honor the rdomain in which it runs when configuring
      the default route.
    o Withdrew all proposals on slaacd(8) startup to prevent indefinite
      retention of nameservers on interfaces no longer flagged for
    o Modified ldpd(8) to lookup the adjacency by LSR id as well as
      source IP address, as the remote peer may change its LSR id.
    o Added support for printing RFC 2332 NBMA Next Hop Resolution
      Protocol (NHRP) to tcpdump(8).
    o Added tcpdump(8) support for printing RFC 8300 Network Service
      Header (NSH).

      packet where the packet length was smaller than the size of the
      usbpcap header.
    o Rewrote dhcpv6 parsing in tcpdump(8) to match the RFC, correctly
      handling dhcpv6 messages.
    o Accept netmask for IPv6 in ifconfig(8) instead of ignoring it and
      using only the prefixlen argument.
    o Fixed snmp(1) agent address parsing to allow IPv6 addresses to be
      used based on format, allow those without brackets to skip the
      port if it results in a nonsensical address (allowing use of ::1),
      and try to connect to the address immediately.
    o Implemented a df subcommand for snmp(1) which outputs disk and
      memory information in a df(1) format.
    o Implemented a -Cs option in snmp(1) for snmp walk and bulkwalk,
      allowing subsections of a tree to be skipped.
    o Introduced option filter-pf-addresses to snmpd.conf(5), allowing
      the OPENBSD-PF-MIB::pfTblAddrTable tree to be filtered out when
      many prefixes are stored in pf tables, reducing CPU usage during
      bulk walks.

    o In pf(4), ensured rdr-to with loopback destination will work even
      when IP forwarding is disabled.
    o Enabled rpki-client(8), a free, easy-to-use implementation of the
      Resource Public Key Infrastructure (RPKI) for Relying Parties (RP)
      to facilitate validation of the Route Origin of a BGP
      announcement. The program queries the RPKI repository system and
      outputs Validated ROA Payloads in the configuration format of
      OpenBGPD, BIRD, and also as CSV or JSON objects for consumption by
      other routing stacks.
    o Modified root's crontab(1) to run rpki-client(8) and reload
      bgpd(8) configuration, enabling RPKI ROA filtering.
    o Stopped hardcoding the cache directory in rpki-client(8). Cache
      and output directory will use defaults for root users and must be
      specified by non-root users.
    o Made rpki-client(8) use the existing cache and not exit if
      rsync(1) exits non-zero.
    o Fixed rpki-client(8) -j option, which had not been producing any
    o Rewrote the time validity check for mtfs in rpki-client(8) to
      correctly account for the timezone.

    o Implemented unwindctl(8) status memory to show cache memory usage.
    o Allowed forcing specific domains to be resolved by specific
      resolvers in unwind.conf(5), handling typical split-horizon
    o Measured performance of resolving strategies in unwind(8), sorting
      them and choosing the next best strategy when one fails.
      Performance data decays over time.
    o Switched captive portal detection from HTTP probing to DNS probing
      in unwind(8).
    o Implemented DNS proposals in unwind(8) to learn nameservers from
      network autoconfiguration daemons.
    o Added opportunistic DoT support to unwind(8).
    o Added an ASR resolver type to unwind(8), using the libc
      asynchronous resolver directly with DHCP-provided nameservers to
      work around broken middle boxes.

      encryption/decryption, configurable per policy with the new
      'rdomain' option in iked.conf(5).
    o Changed the default ipsec level set by iked(8) and isakmpd(8) to
      IPSEC_LEVEL_REQUIRE. Unencrypted packets matching incoming ipsec
      flows are no longer accepted by default.

      the default Diffie-Hellman group configuration for IKE SAs in
    o Removed support for the insecure EC2N Diffie-Hellman groups in
    o Changed the default authentication method in iked(8) to generic
      signature authentication (RFC 7427).
    o Added ESN configuration options for ikesa in iked.conf(5).
    o Added transport mode for child SAs to iked(8).
    o Added active probing for lost connection in iked(8) resulting in a
      faster connection reset.

      non-standard UDP encapsulation port.
    o Added support for multiple x509 extensions and multiple
      subjectAltName fields in certificates used with iked(8).
    o Added support for certificates with uppercase subjectAltNames in
    o Removed automatically installed ipsec(4) flow blocking unencrypted
      IPv6 traffic in iked(8).
    o Reduced size of IKE_AUTH message by eliminating duplicate traffic
      selectors in iked(8).
    o Added an ikectl(8) "show sa" command to print information about
      the state of negotiated IKE SAs, their child SAs and the resulting
      IPsec flows.
    o Added an ikectl(8) "reset id" command to reset all SAs from
      policies with matching destination IDs.
    o Added support for UDP encapsulation in manual SAs set up with

      ikectl(8) reload command.
    o Corrected iked(8) calculation of IPv6 address leases from small
      address pools.
    o Fixed several bugs that could lead to iked(8) selecting a false
      policy for incoming requests, resulting in a failed handshake.
    o Fixed a bug that broke PSK authentication against Strongswan.
    o Enabled UDP-encapsulation in Child SAs if iked(8) was started with
    o Fixed isakmpd(8) IKE pcap file creation.

      without notes with -N.
    o Added tmux(1) support for adding a note to a key binding with
      bind-key -N and using this to add descriptions to the default key
      binding. Using list-keys -N shows key bindings with notes. Changed
      the default ? binding to show a readable summary of keys.

    o Fixed an issue where a vmm(4) guest could write to host memory by
      passing bogus addresses in pvclock(4).
    o Run cu(1) in restricted mode using -r in vmctl(8) and ldomctl(8).
    o Started virtual machines defined in vm.conf(5) in a staggered
      fashion, helping prevent overload of the host and improper tsc
      calibration in guests.

    o New Features
       - Allowed use of the smtpd(8) session username in built-in
         filters when available.
       - Introduced a bypass keyword to smtpd(8) so that built-in
         filters can bypass processing when a condition is met.
       - Allowed use of 'auth' as an origin in smtpd.conf(5).
       - Allowed use of mail-from and rctp-to as for and from
         parameters in smtpd.conf(5).

         out-of-bounds read in smtpd allowing an attacker to inject
         arbitrary commands into the envelope file to be executed as
         root, and ensured privilege revocation in smtpctl(8) to
         prevent arbitrary commands from being run with the _smtpq
       - Allowed mail.local(8) to be run as non-root, opening a pipe
         to lockspool(1) for file locking.
       - Fixed a security vulnerability in smtpd(8) which could lead

         int value.

 - OpenSSH 8.3
    o Potentially incompatible changes.
       - sftp(1): reject an argument of "-1" in the same way as ssh(1)
         and scp(1) do instead of accepting and silently ignoring it.
       - Removed ssh-rsa (SHA1) from the list of allowed CA signature
       - Removed diffie-hellman-group14-sha1 from the default ssh(1)
         key exchange.
       - ssh-keygen(1): the command-line options related to the
         generation and screening of safe prime numbers used by the
         diffie-hellman-group-exchange-* key exchange algorithms have
         changed. Most options have been folded under the -O flag.
       - sshd(8): the sshd listener process title visible to ps(1) has
         changed to include information about the number of
         connections that are currently attempting authentication and
         the limits configured by MaxStartups.
       - ssh-sk-helper(8): this is a new binary. It is used by the
         FIDO/U2F support to provide address-space isolation for token
         middleware libraries (including the internal one). It needs
         to be installed in the expected path under /usr/libexec.
    o New Features
       - Allowed use of the IgnoreRhosts directive anywhere in an
         sshd_config(5) file, not just before Match blocks, and made
         it a tri-state option.

         of a private key file if no corresponding public key file is
       - Gave ssh-keygen(1) the ability to dump the contents of a
         binary key revocation list with ssh-keygen -lQf /path.
       - Added ssh(1) -Q key-sig option for all key and signature
         types, teaching ssh -Q to accept ssh_config(5) and
         sshd_config(5) algorithm keywords as an alias for the
         corresponding query.
       - Updated to libfido2 780ad3c25.
       - Added an sshd_config(5) "Include" directive to allow
         inclusion of files.
       - Renamed ssh-add(1) -O to -K to load resident keys from a FIDO
       - Added the ability to download FIDO2 resident keys from a
         token via the ssh-keygen(1) -K option and save public/private
         keys into the current directory.
       - Implemented support for generating FIDO2 resident keys.
         "ssh-add -O" will load resident keys from a FIDO2 token and
         add them to an ssh-agent. Removed the -x option currently
         used for the FIDO/U2F-specific key flags, now under -O.
       - Removed single letter flags for moduli generation in
         ssh-keygen(1) and moved all moduli generation options to
         under the -O flag. Breaks existing ssh-keygen commandline
         syntax for moduli-related operations.
       - Allowed forwarding of a different agent socket to a specified
         path in ssh(1).
       - Allowed ssh(1) security keys to act as host keys as well as
         user keys.
       - Used ssh-sk-helper for all security key signing operations
         and security key enrollment. Most ssh(1) tools no longer need
         to link against libfido2 or interact with /dev/uhid*
       - Added "no-touch-required" options to ssh-keygen(1) and
         sshd(8) to disable touch requirement for authorized_keys and
       - Added an sshd_config(5) PubkeyAuthOptions directive allowing
         specification of whether sshd(8) should check whether user
         presence was tested before a security key was made.
       - Added direct support for U2F/FIDO2 security keys in ssh(1).
       - Added initial infrastructure for U2F/FIDO support in ssh(1).
       - Notified the user via TTY or $SSH_ASKPASS when ssh(1)
         security keys must be tapped/touched in order to perform a
         signature operation.
       - Enabled ed25519 support in ssh(1).
    o Bugfixes
       - Detected and prevented simple ssh(1) configuration loops when
         using ProxyJump.
       - Fixed PIN entry bugs on FIDO in ssh-keygen(1).
       - Fixed ssh-keygen(1) not displaying the authenticator touch
       - Prevented a timeout in ssh(1) when the server doesn't
         immediately send a banner, such as with multiplexers like
       - Adjusted on-wire signature encoding for ecdsh-sk ssh(1) keys
         to better match ec25519-sk keys.

       - ssh(1): fix IdentitiesOnly=yes to also apply to keys loaded
         from a PKCS11Provider
       - ssh-keygen(1): avoid NULL dereference when trying to convert
         an invalid RFC4716 private key.
       - scp(2): when performing remote-to-remote copies using "scp
         -3", start the second ssh(1) channel with BatchMode=yes
         enabled to avoid confusing and non-deterministic ordering of
       - ssh(1): fix incorrect error message for "too many known hosts
       - ssh(1): make failures when establishing "Tunnel" forwarding
         terminate the connection when ExitOnForwardFailure is enabled
       - ssh-keygen(1): fix printing of fingerprints on private keys
         and add a regression test for same.
       - sshd(8): document order of checking AuthorizedKeysFile
         (first) and AuthorizedKeysCommand (subsequently, if the file
         doesn't match)
       - sshd(8): document that /etc/hosts.equiv and /etc/shosts.equiv
         are not considered for HostbasedAuthentication when the
         target user is root
       - ssh(1), ssh-keygen(1): fix NULL dereference in private
         certificate key parsing (oss-fuzz #20074).
       - ssh(1), sshd(8): more consistency between sets of %TOKENS are
         accepted in various configuration options.
       - ssh(1), ssh-keygen(1): improve error messages for some common
         PKCS#11 C_Login failure cases
       - ssh(1), sshd(8): make error messages for problems during SSH
         banner exchange consistent with other SSH transport-layer
         error messages and ensure they include the relevant IP
       - various: fix a number of spelling errors in comments and
         debug/error messages
       - ssh-keygen(1), ssh-add(1): when downloading FIDO2 resident
         keys from a token, don't prompt for a PIN until the token has
         told us that it needs one. Avoids double-prompting on devices
         that implement on-device authentication.
       - sshd(8), ssh-keygen(1): no-touch-required FIDO certificate
         option should be an extension, not a critical option.
       - ssh(1), ssh-keygen(1), ssh-add(1): offer a better error
         message when trying to use a FIDO key function and
         SecurityKeyProvider is empty.
       - ssh-add(1), ssh-agent(8): ensure that a key lifetime fits
         within the values allowed by the wire format (u32). Prevents
         integer wraparound of the timeout values

 - Mandoc 1.14.6
    o Introduced a new mdoc(7) macro .Tg ("tag") to explicitly mark a
      place as defining a term, and improved automatic tagging in
      various ways.
    o Print the manpath when the man(1) -w option is given without an
      argument, for compatibility with the man-1.6 and man-db
    o Deleted support for the _whatdb configuration directive from
      man.conf(5) five years after it was declared obsolete; use manpath
    o Added a Content-Security-Policy HTTP header to man.cgi(8) that
      allows only CSS.
    o Provide a STYLE message when mandoc(1) knows the filename and the
      extension disagrees with the section number given in the .Dt or
      .TH macro.
    o When the mdoc(7) .Dd macro lacks an argument, use the empty
      string, and always concatenate all arguments, no matter their
      number. The same change was applied to groff.

 - Ports and packages:
    The package system provides an easy way to install 3rd party software.
    New features include:
    o Provide debug package information that can be installed alongside
      packages and used to provide better bug reports.
    o Added DEBUG_PKG_CACHE functionality to pkg_add(1), fetching debug
      patches when packages are installed.
    o Added a -d option to pkg_add(1) to add debug packages if present
      alongside intended updates or additions.
    o Added support for "alpha" suffixes in packages-specs(7), removing
      the need for workarounds in certain ports distfiles.
    o Pre-built packages are available for the following architectures on
      the day of release:
       - aarch64 (arm64): 10848
       - amd64: 11268
       - i386: 10715
       - mips64: 9281
       - sparc64: 9850
    o Packages for the following architectures will be made available as
      their builds complete:
       - arm
       - mips64el
       - powerpc

 - As usual, steady improvements in manual pages and other documentation.

 - The system includes the following major components from outside suppliers:
    o Xenocara (based on X.Org 7.7 with xserver 1.20.8 + patches,
      freetype 2.10.1, fontconfig 2.12.4, Mesa 19.2.8, xterm 351,
      xkeyboard-config 2.20 and more)
    o LLVM/Clang 8.0.1 (+ patches)
    o GCC 4.2.1 (+ patches) and 3.3.6 (+ patches)
    o Perl 5.30.2 (+ patches)

    o Awk Dec 20, 2012 version
    o Expat 2.2.8

- SECURITY AND ERRATA --------------------------------------------------

We provide patches for known security threats and other important
issues discovered after each release.  Our continued research into
security means we will find new security problems -- and we always
provide patches as soon as possible.  Therefore, we advise regular
visits to

- MAILING LISTS AND FAQ ------------------------------------------------

Mailing lists are an important means of communication among users and
developers of OpenBSD.  For information on OpenBSD mailing lists, please

You are also encouraged to read the Frequently Asked Questions (FAQ) at:

- DONATIONS ------------------------------------------------------------

The OpenBSD Project is a volunteer-driven software group funded by
donations.  Besides OpenBSD itself, we also develop important software
like OpenSSH, LibreSSL, OpenNTPD, OpenSMTPD, the ubiquitous pf packet
filter, the quality work of our ports development process, and many
others.  This ecosystem is all handled under the same funding umbrella.

We hope our quality software will result in contributions that maintain
our build/development infrastructure, pay our electrical/internet costs,
and allow us to continue operating very productive developer hackathon

All of our developers strongly urge you to donate and support our future
efforts.  Donations to the project are highly appreciated, and are
described in more detail at:

- OPENBSD FOUNDATION ---------------------------------------------------

For those unable to make their contributions as straightforward gifts,
the OpenBSD Foundation ( is a Canadian
not-for-profit corporation that can accept larger contributions and
issue receipts.  In some situations, their receipt may qualify as a
business expense write-off, so this is certainly a consideration for
some organizations or businesses.

There may also be exposure benefits since the Foundation may be
interested in participating in press releases.  In turn, the Foundation
then uses these contributions to assist OpenBSD's infrastructure needs.
Contact the foundation directors at for
more information.

- HTTPS INSTALLS -------------------------------------------------------

OpenBSD can be easily installed via HTTPS downloads.  Typically you need
a single small piece of boot media (e.g., a USB flash drive) and then
the rest of the files can be installed from a number of locations,
including directly off the Internet.  Follow this simple set of
instructions to ensure that you find all of the documentation you will
need while performing an install via HTTPS.

1) Read either of the following two files for a list of HTTPS mirrors
   which provide OpenBSD, then choose one near you:

   As of May 19, 2020, the following HTTPS mirror sites have the
   6.7 release:            Global         Stockholm, Sweden          Frankfurt, Germany           Oldenburg, Germany         Paris, France       Brisbane, Australia        CO, USA       CA, USA            TX, USA     Toronto, Canada Global     Global

        The release is also available at the master site:            Alberta, Canada

        However it is strongly suggested you use a mirror.

   Other mirror sites may take a day or two to update.

2) Connect to that HTTPS mirror site and go into the directory
   pub/OpenBSD/6.7/ which contains these files and directories.
   This is a list of what you will see:

        ANNOUNCEMENT     armv7/        octeon/             sparc64/
        README           hppa/ src.tar.gz
        SHA256           i386/         packages/           sys.tar.gz
        SHA256.sig       landisk/      packages-stable/    xenocara.tar.gz
        alpha/           loongson/     ports.tar.gz
        amd64/           luna88k/      root.mail
        arm64/           macppc/       sgi/

   It is quite likely that you will want at LEAST the following
   files which apply to all the architectures OpenBSD supports.

        README          - generic README
        root.mail       - a copy of root's mail at initial login.
                          (This is really worthwhile reading).

3) Read the README file.  It is short, and a quick read will make
   sure you understand what else you need to fetch.

4) Next, go into the directory that applies to your architecture,
   for example, amd64.  This is a list of what you will see:

        BOOTIA32.EFI*   bsd*            floppy67.fs     pxeboot*
        BOOTX64.EFI**         game67.tgz      xbase67.tgz
        BUILDINFO       bsd.rd*         index.txt       xfont67.tgz
        INSTALL.amd64   cd67.iso        install67.fs    xserv67.tgz
        SHA256          cdboot*         install67.iso   xshare67.tgz
        SHA256.sig      cdbr*           man67.tgz
        base67.tgz      comp67.tgz      miniroot67.fs

   If you are new to OpenBSD, fetch _at least_ the file INSTALL.amd64
   and install67.iso.  The install67.iso file (roughly 470MB in size)
   is a one-step ISO-format install CD image which contains the various
   *.tgz files so you do not need to fetch them separately.

   If you prefer to use a USB flash drive, fetch install67.fs and
   follow the instructions in INSTALL.amd64.

5) If you are an expert, follow the instructions in the file called
   README; otherwise, use the more complete instructions in the
   file called INSTALL.amd64.  INSTALL.amd64 may tell you that you
   need to fetch other files.

6) Just in case, take a peek at:

   This is the page where we talk about the mistakes we made while
   creating the 6.7 release, or the significant bugs we fixed
   post-release which we think our users should have fixes for.
   Patches and workarounds are clearly described there.

- X.ORG FOR MOST ARCHITECTURES -----------------------------------------

X.Org has been integrated more closely into the system.  This release
contains X.Org 7.7.  Most of our architectures ship with X.Org, including
amd64, sparc64 and macppc.  During installation, you can install X.Org
quite easily using xenodm(1), our simplified X11 display manager forked
from xdm(1).

- PACKAGES AND PORTS ---------------------------------------------------

Many third party software applications have been ported to OpenBSD and
can be installed as pre-compiled binary packages on the various OpenBSD
architectures.  Please see for
more information on working with packages and ports.

Note: a few popular ports, e.g., NSD, Unbound, and several X
applications, come standard with OpenBSD and do not need to be installed

- SYSTEM SOURCE CODE ---------------------------------------------------

The source code for all four subsystems can be found in the
pub/OpenBSD/6.7/ directory:

        xenocara.tar.gz     ports.tar.gz   src.tar.gz     sys.tar.gz

The README ( file
explains how to deal with these source files.
