and CRL validity times. The 'expires' value can be used to avoid route
selection based on stale data when generating VRP sets, when faced
with loss of communication between consumer and validator, or
validator and CA repository.
<li>Made the runtime timeout (-s option) also trigger in
child processes.
<li>Improved RRDP support and make RRDP the default protocol for
synchronizing the RPKI repository data, with <a

support, keep-alive).
<li>In RRDP, do not access URI with userinfo (@-sign)
<li>Improved RRDP syncing by considering a notification file serial
jumping backwards as synced repository.
<li>Made -R (rsync only) also apply to the fetching of TA files.
<li>Only sync *.{cer,crl,gbr,mft,roa} files via rsync and exclude all others.
<li>When producing output for <a
href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>, make use of the
'roa-set expires' attribute to prevent machines from loading outdated
roa-sets.
<li>In RRDP, limited the number of deltas to 300 per repo. If more deltas
exist, downloading a full snapshot is faster.
<li>Limited the validation depth of X.509 certificate chains to 12, double
the current depth seen in RPKI.
</ul>
<li><a href="https://man.openbsd.org/traceroute.8">traceroute(8)</a> was improved:
<ul>
<li>Probe packets are now sent in quick succession and responses handled asynchronously.</li>
<li>DNS lookups are performed asynchronously.
This speeds up the time required to display results considerably.
</ul>

defer to <a
href="https://man.openbsd.org/dhcpleased.8">dhcpleased(8)</a> when the
inet autoconf flag is set. When run, dhclient will signal dhcpleased
to request a new lease rather than requesting one itself.
<li>Fixed potential races in <a
href="https://man.openbsd.org/slaacd.8">slaacd(8)</a> and <a
href="https://man.openbsd.org/dhcpleased.8">dhcpleased(8)</a> when two
processes are configuring the same IP.

href="https://man.openbsd.org/dhcpleased.8">dhcpleased(8)</a> always
configure provided routes, regardless of whether the address received
in the lease is already configured.
<li>Used exclusive locks under /dev/ to ensure single instances of <a
href="https://man.openbsd.org/resolvd.8">resolvd(8)</a>, <a
href="https://man.openbsd.org/slaacd.8">slaacd(8)</a> and <a
href="https://man.openbsd.org/dhcpleased.8">dhcpleased(8)</a>.
<li>Implemented classless static routes DHCP option in <a
href="https://man.openbsd.org/dhcpleased.8">dhcpleased(8)</a>.
<li>Added a new "nameserver" command to <a
href="https://man.openbsd.org/route.8">route(8)</a>, sending
nameserver proposals to <a
href="https://man.openbsd.org/resolvd.8">resolvd(8)</a> using the DNS
proposal protocol over the route socket. This command is intended be
used to integrate userland triggered nameserver changes, for example
by VPN software.

</ul>
<li>Internal Improvements
<ul>
<li>Numerous fixes and improvements to the new X.509 validator to ensure compatible error codes
and callback support compatible with the legacy OpenSSL validator.
</ul>
</ul>
<li>OpenSSH 8.8
<ul>
<li>Security
<ul>
<li><a href='https://man.openbsd.org/sshd.8'>sshd(8)</a>: OpenSSH
8.5 introduced the LogVerbose keyword. When this option was
enabled with a set of patterns that activated logging in code
that runs in the low-privilege sandboxed sshd process, the log
messages were constructed in such a way that printf(3) format
strings could effectively be specified the low-privilege code.
<li><a href='https://man.openbsd.org/sshd.8'>sshd(8)</a> from
OpenSSH 6.2 through 8.7 failed to correctly initialise
supplemental groups when executing an AuthorizedKeysCommand or
AuthorizedPrincipalsCommand, where a AuthorizedKeysCommandUser
or AuthorizedPrincipalsCommandUser directive has been set to
run the command as a different user.
</ul>
<li>Potentially incompatible changes
<ul>
<li>A near-future release of OpenSSH will switch <a
href='https://man.openbsd.org/scp.1'>scp(1)</a> from using
the legacy scp/rcp protocol to using SFTP by default.
<li>This release disables RSA signatures using the SHA-1 hash
algorithm by default.
<li><a href='https://man.openbsd.org/scp.1'>scp(1)</a>: this
release changes the behaviour of remote to remote copies
(e.g. "scp host-a:/path host-b:") to transfer through the
local host by default. This was previously available via the
-3 flag. This mode avoids the need to expose credentials on
the origin hop, avoids triplicate interpretation of filenames
by the shell (by the local system, the copy origin and the
destination) and, in conjunction with the SFTP support for
<a href='https://man.openbsd.org/scp.1'>scp(1)</a> mentioned
below, allows use of all authentication methods to the remote
hosts (previously, only non-interactive methods could be
used). A -R flag has been added to select the old behaviour.
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>/<a
href='https://man.openbsd.org/sshd.8'>sshd(8)</a>: both the
client and server are now using a stricter configuration file
parser. The new parser uses more shell-like rules for quotes,
space and escape characters. It is also more strict in
rejecting configurations that include options lacking
arguments. Previously some options (e.g. DenyUsers) could
appear on a line with no subsequent arguments. This release
will reject such configurations. The new parser will also
reject configurations with unterminated quotes and multiple
'=' characters after the option name.
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>: when using
SSHFP DNS records for host key verification, <a
href='https://man.openbsd.org/ssh.1'>ssh(1)</a> will verify
all matching records instead of just those with the specific
signature type requested. This may cause host key verification
problems if stale SSHFP records of a different or legacy
signature type exist alongside other records for a particular
host.
<li><a href='https://man.openbsd.org/ssh-keygen.1'>ssh-keygen(1)</a>:
when generating a FIDO key and specifying an explicit
attestation challenge (using -Ochallenge), the challenge will
now be hashed by the builtin security key middleware. This
removes the (undocumented) requirement that challenges be
exactly 32 bytes in length and matches the expectations of
libfido2.
<li><a href='https://man.openbsd.org/sshd.8'>sshd(8)</a>:
environment="..." directives in authorized_keys files are now
first-match-wins and limited to 1024 discrete environment
variable names.
</ul>
<li>New features
<ul>
<li><a href='https://man.openbsd.org/scp.1'>scp(1)</a>:
experimental support for transfers using the SFTP protocol as
a replacement for the venerable SCP/RCP protocol that it has
traditionally used. SFTP offers more predictable filename
handling and does not require expansion of glob(3) patterns
via the shell on the remote side.
<li><a href='https://man.openbsd.org/sftp-server.8'>sftp-server(8)</a>:
add a protocol extension to support expansion of ~/ and ~user/
prefixed paths. This was added to support these paths when
used by <a href='https://man.openbsd.org/scp.1'>scp(1)</a>
while in SFTP mode.
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>: add a
ForkAfterAuthentication
<a href='https://man.openbsd.org/ssh_config.5'>ssh_config(5)</a>
counterpart to the <a href='https://man.openbsd.org/ssh.1'>ssh(1)</a> -f flag.
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>: add a
StdinNull directive to
<a href='https://man.openbsd.org/ssh_config.5'>ssh_config(5)</a>
that allows the config file to do the same thing as -n does on
the <a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>
command- line.
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>: add a
SessionType directive to ssh_config, allowing the
configuration file to offer equivalent control to the -N (no
session) and -s (subsystem) command-line flags.
<li><a href='https://man.openbsd.org/ssh-keygen.1'>ssh-keygen(1)</a>:
allowed signers files used by
<a href='https://man.openbsd.org/ssh-keygen.1'>ssh-keygen(1)</a>
signatures now support listing key validity intervals
alongside the keys, and
<a href='https://man.openbsd.org/ssh-keygen.1'>ssh-keygen(1)</a>
can optionally check during signature verification whether a
specified time falls inside this interval. This feature is
intended for use by git to support signing and verifying
objects using ssh keys.
<li><a href='https://man.openbsd.org/ssh-keygen.8'>ssh-keygen(8)</a>:
support printing of the full public key in a sshsig signature
via a -Oprint-pubkey flag.
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>: allow the
<a
href='https://man.openbsd.org/ssh_config.5'>ssh_config(5)</a>
CanonicalizePermittedCNAMEs directive to accept a "none"
argument to specify the default behaviour.
</ul>
<li>Bugfixes
<ul>
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>/
<a href='https://man.openbsd.org/sshd.8'>sshd(8)</a>: start
time-based re-keying exactly on schedule in the client and
server mainloops. Previously the re-key timeout could expire
but re-keying would not start until a packet was sent or
received, causing a spin in select() if the connection was
quiescent.
<li><a href='https://man.openbsd.org/ssh-keygen.1'>ssh-keygen(1)</a>:
avoid Y2038 problem in printing certificate validity
lifetimes. Dates past 2^31-1 seconds since epoch were
displayed incorrectly on some platforms.
<li><a href='https://man.openbsd.org/scp.1'>scp(1)</a>: allow
spaces to appear in usernames for local to remote and scp -3
remote to remote copies.
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>/
<a href='https://man.openbsd.org/sshd.8'>sshd(8)</a>: remove
references to ChallengeResponseAuthentication in favour of
KbdInteractiveAuthentication. The former is what was in SSHv1,
the latter is what is in SSHv2 (<a href='https://tools.ietf.org/html/rfc4256'>RFC4256</a>)
and they were treated as somewhat but not entirely equivalent. We
retain the old name as a deprecated alias so configuration
files continue to work as well as a reference in the man page
for people looking for it.
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>/
<a href='https://man.openbsd.org/ssh-add.1'>ssh-add(1)</a>/
<a href='https://man.openbsd.org/ssh-keygen.1'>ssh-keygen(1)</a>:
fix decoding of X.509 subject name when extracting a key from
a PKCS#11 certificate.
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>: restore
blocking status on stdio fds before close.
<a href='https://man.openbsd.org/ssh.1'>ssh(1)</a> needs file
descriptors in non-blocking mode to operate but it was not
restoring the original state on exit. This could cause
problems with fds shared with other programs via the shell.
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>/
<a href='https://man.openbsd.org/sshd.8'>sshd(8)</a>: switch both
client and server mainloops from select(3) to
pselect(3). Avoids race conditions where a signal may arrive
immediately before select(3) and not be processed until an
event fires.
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>: sessions
started with ControlPersist were incorrectly executing a shell
when the -N (no shell) option was specified.
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>: check if
IPQoS or TunnelDevice are already set before
overriding. Prevents values in config files from overriding
values supplied on the command line.
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>: fix debug
message when finding a private key to match a certificate
being attempted for user authentication. Previously it would
print the certificate's path, whereas it was supposed to be
showing the private key's path.
<li><a href='https://man.openbsd.org/sshd.8'>sshd(8)</a>: match
host certificates against host public keys, not private
keys. Allows use of certificates with private keys held in a
ssh-agent.
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>: add a
workaround for a bug in OpenSSH 7.4 <a href='https://man.openbsd.org/sshd.8'>sshd(8)</a>,
which allows RSA/SHA2 signatures for public key authentication but
fails to advertise this correctly via SSH2_MSG_EXT_INFO. This
causes clients of these server to incorrectly match
PubkeyAcceptedAlgorithms and potentially refuse to offer
valid keys.
<li><a href='https://man.openbsd.org/sftp.1'>sftp(1)</a>/
<a href='https://man.openbsd.org/scp.1'>scp(1)</a>: degrade
gracefully if a sftp-server offers the limits@openssh.com
extension but fails when the client tries to invoke it.
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>: allow
ssh_config SetEnv to override $TERM, which is otherwise
handled specially by the protocol. Useful in ~/.ssh/config to
set TERM to something generic (e.g. "xterm" instead of
"xterm-256color") for destinations that lack terminfo entries.
<li><a href='https://man.openbsd.org/sftp-server.8'>sftp-server(8)</a>:
the limits@openssh.com extension was incorrectly marked as an
operation that writes to the filesystem, which made it
unavailable in sftp-server read-only mode.
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>: fix SEGV
in UpdateHostkeys debug() message, triggered when the update
removed more host keys than remained present.
<li><a href='https://man.openbsd.org/scp.1'>scp(1)</a>: when using
the SFTP protocol, continue transferring files after a
transfer error occurs, better matching original scp/rcp
behaviour.
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>: fixed a
number of memory leaks in multiplexing,
<li><a href='https://man.openbsd.org/ssh-keygen.1'>ssh-keygen(1)</a>:
avoid crash when using the -Y find-principals command.
<li>A number of documentation and manual improvements.

<p>
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.
<h3>OpenBSD/hppa:</h3>
<p>
Boot over the network by following the instructions in INSTALL.hppa or the
<a href="hppa.html#install">hppa platform page</a>.
<h3>OpenBSD/i386:</h3>
<p>
If your machine can boot from CD, you can write <i>install70.iso</i> or
<i>cd70.iso</i> to a CD and boot from it.
You may need to adjust your BIOS options first.
<p>
If your machine can boot from USB, you can write <i>install70.img</i> or
<i>miniroot70.img</i> to a USB stick and boot from it.
<p>
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.
<p>
If you are planning on dual booting OpenBSD with another OS, you will need to
read INSTALL.i386.
<h3>OpenBSD/landisk:</h3>
<p>
Write <i>miniroot70.img</i> to the start of the CF
or disk, and boot normally.
<h3>OpenBSD/loongson:</h3>
<p>
Write <i>miniroot70.img</i> 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.
<h3>OpenBSD/luna88k:</h3>
<p>
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.
<h3>OpenBSD/macppc:</h3>
<p>
Burn the image from a mirror site to a CDROM, and power on your machine
while holding down the <i>C</i> key until the display turns on and
shows <i>OpenBSD/macppc boot</i>.
<p>
Alternatively, at the Open Firmware prompt, enter <i>boot cd:,ofwboot
/7.0/macppc/bsd.rd</i>
<h3>OpenBSD/octeon:</h3>
<p>
After connecting a serial port, boot bsd.rd over the network via DHCP/tftp.
Refer to the instructions in INSTALL.octeon for more details.
<h3>OpenBSD/powerpc64:</h3>
<p>
To install, write <i>install70.img</i> or <i>miniroot70.img</i> to a
USB stick, plug it into the machine and choose the <i>OpenBSD
install</i> menu item in Petitboot.
Refer to the instructions in INSTALL.powerpc64 for more details.
<h3>OpenBSD/riscv64:</h3>
<p>
To install, write <i>install70.img</i> or <i>miniroot70.img</i> 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.
<h3>OpenBSD/sparc64:</h3>
<p>
Burn the image from a mirror site to a CDROM, boot from it, and type
<i>boot cdrom</i>.
<p>
If this doesn't work, or if you don't have a CDROM drive, you can write
<i>floppy70.img</i> or <i>floppyB70.img</i>
(depending on your machine) to a floppy and boot it with <i>boot
floppy</i>. Refer to INSTALL.sparc64 for details.
<p>
Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
will most likely fail.
<p>
You can also write <i>miniroot70.img</i> to the swap partition on
the disk and boot with <i>boot disk:b</i>.
<p>
If nothing works, you can boot over the network as described in INSTALL.sparc64.

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.

<h3>Ports Tree</h3>
<p>
A ports tree archive is also provided. To extract:
<blockquote><pre>
# <kbd>cd /usr</kbd>
# <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
</pre></blockquote>
<p>
Go read the <a href="faq/ports/index.html">ports</a> 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.
<p>
The <i>ports/</i> directory represents a CVS checkout of our ports.
As with our complete source tree, our ports tree is available via
<a href="anoncvs.html">AnonCVS</a>.
So, in order to keep up to date with the -stable branch, you must make
the <i>ports/</i> tree available on a read-write medium and update the tree
with a command like:
<blockquote><pre>
# <kbd>cd /usr/ports</kbd>
# <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_0</kbd>
</pre></blockquote>
<p>
[Of course, you must replace the server name here with a nearby anoncvs
server.]
<p>
Note that most ports are available as packages on our mirrors. Updated
ports for the 7.0 release will be made available if problems arise.
<p>
If you're interested in seeing a port added, would like to help out, or just
would like to know more, the mailing list
<a href="mail.html">ports@openbsd.org</a> is a good place to know.
