would cause validity problems.
</ul>
<li>In <a href="https://man.openbsd.org/bgpd.conf.5">bgpd(8)</a>,
<ul>
<li>The <a href="https://man.openbsd.org/bgpd.8">bgpd</a> login

</ul>
<li>LibreSSL version 3.5.2
<ul>
<li>New Features
<ul>
<li>The RFC 3779 API was ported from OpenSSL.<br>
Many bugs were fixed, regression tests were added and the code was cleaned up.
<li>Certificate Transparency was ported from OpenSSL.<br>
Many internal improvements were made, resulting in cleaner and safer code.<br>
Regress coverage was added. libssl does not yet make use of it.
</ul>
<li>Portable Improvements
<ul>
<li>Enabled ASAN CI on Linux platform.<br>
<li>Fixed various POSIX compliance and other portability issues<br>
found by the port to the Sortix operating system.
<li>Add libmd as platform specific libraries for Solaris.<br>
<li>Set IA-64 compiler flag only if it is HP-UX with IA-64.<br>
<li>Enabled and scheduled Coverity scans.<br>
</ul>
<li>Compatibility Changes
<ul>
<li>Most structs that were previously defined in the following headers
are now opaque as they are in OpenSSL 1.1:<br>
bio.h, bn.h, comp.h, dh.h, dsa.h, evp.h, hmac.h, ocsp.h, rsa.h,
x509.h, x509v3.h, x509_vfy.h
<li>Switch TLSv1.3 cipher names from AEAD- to OpenSSL's TLS_<br>
OpenSSL added the TLSv1.3 ciphersuites with "RFC names" instead
of using something consistent with the previous naming.<br>
Various test suites expect these names (instead of checking for the much
more sensible cipher numbers).<br>
The old names are still accepted as aliases.
<li>Subject alternative names and name constraints are now validated
when they are added to certificates.<br>
Various interoperability problems with stacks that validate
certificates more strictly than OpenSSL can be avoided this way.
<li>Attempt to opportunistically use the host name for SNI in s_client
<li>Allow non-standard name constraints of the form @domain.com.
</ul>
<li>Bug fixes
<ul>
<li>Avoid infinite loop for custom curves of order 1.<br>
<li>Avoid infinite loop on parsing DSA private keys.<br>
<li>Prevent a malicious certificate from causing an infinite loop.<br>
<li>In some situations, the verifier would discard the error on an
unvalidated certificate chain.<br>
This would happen when the verification callback was in use,
instructing the verifier to continue unconditionally.<br>
This could lead to incorrect decisions being made in software.
<li>Avoid an infinite loop in SSL_shutdown()
<li>Handle zero byte reads/writes that trigger handshakes in the
TLSv1.3 stack.
<li>A long standing memleak in libtls CRL handling was fixed
<li>Allow name constraints with a leading dot.
<li>Fix NULL dereferences in openssl(1) cms option parsing.
<li>Do not zero the computed cofactor on ec_guess_cofactor() success.
<li>Bound cofactor in EC_GROUP_set_generator() to reduce the number of
bogus groups that can be described with nonsensical parameters.
<li>Avoid various potential segfaults in EVP_PKEY_CTX_free() in low
memory conditions.
</ul>

notBefore and notAfter times when X.509 certificates are parsed.
<li>The X.509 lookup code has been simplified and cleaned up.
<li>Fixed numerous issues flagged by coverity and the cryptofuzz project.
<li>Increased the number of Miller-Rabin checks in DH and DSA
key/parameter generation.
<li>Started using the bytestring API in libcrypto for cleaner and
safer code.
<li>Convert asn1_d2i_ex_primitive()/asn1_collect() from BUF_MEM to CBB
<li>Clean up d2i_ASN1_BOOLEAN() and i2d_ASN1_BOOLEAN()

<li>Improve SNI hostname validation
<li>Ensure SSL_set_tlsext_host_name() is given a valid hostname
<li>Factor out/rewrite DHE key exchange
<li>Convert server serialisation of DHE parameters/public key to new
functions
<li>Provide CBS_get_last_u8(), CBS_get_u64(), CBS_add_u64() and various
CBS_peek_* functions.
<li>Use CBS_get_last_u8() to find the content type in TLSv1.3 records
<li>Correct SSL_get_peer_cert_chain() when used with the TLSv1.3 stack
<li>Only allow zero length key shares when we know we're doing HRR
<li>Pull key share group/length CBB code up from
tls13_key_share_public()
<li>Refactor ssl3_get_server_kex_ecdhe() to separate parsing and
validation.
<li>Allocate and free the EVP_AEAD_CTX struct in
tls13_record_protection.
<li>Convert legacy TLS client and server to tls_key_share
<li>Clean up pkey handling in ssl3_get_server_key_exchange()
<li>Fix GOST skip certificate verify handling
<li>Simplify SSL_get_peer_certificate()
<li>Cleanup/simplify ssl_cert_type()

<li>Be more careful with embedded and terminating NULs in the new
name constraints code.
<li>Various minor code cleanup in openssl(1) pkcs12.
<li>Simplify priv_key handling in d2i_ECPrivateKey().
</ul>
<li>Documentation improvements
<ul>
<li>45 new manual pages, most of which were written from scratch.<br>
Documentation coverage of ASN.1 and X.509 code has been
significantly improved.
<li>Update d2i_ASN1_OBJECT(3) documentation to reflect reality after
refactoring and bug fixes.

issues.
</ul>
</ul>
<li>OpenSSH 9.0
<ul>
<li>Security
<ul>
<!-- OpenSSH 8.9 -->
<li>Near miss in <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
fix an integer overflow in the user authentication path
that, in conjunction with other logic errors, could have yielded
unauthenticated access under difficult to exploit conditions.<br>
This situation is not exploitable because of independent checks in
the privilege separation monitor. Privilege separation has been
enabled by default in since <a href="32.html">OpenBSD 3.2</a> (released in 2002) and
has been mandatory since <a href="61.html">OpenBSD 6.1</a> (released in 2017).<br>
</ul>
<li>Potentially incompatible changes
<ul>
<!-- OpenSSH 8.9 -->
<li>In OpenSSH 8.9 the FIDO security key middleware interface
changed and increments SSH_SK_VERSION_MAJOR.
<!-- OpenSSH 9.0 -->
<li>This release switches <a href="https://man.openbsd.org/scp.1">scp(1)</a>
from using the legacy scp/rcp protocol
to using the SFTP protocol by default.<br>
Legacy scp/rcp performs wildcard expansion of remote filenames (e.g.
"scp host:* .") through the remote shell. This has the side effect of
requiring double quoting of shell meta-characters in file names
included on <a href="https://man.openbsd.org/scp.1">scp(1)</a>
command-lines, otherwise they could be interpreted
as shell commands on the remote side.<br>
This creates one area of potential incompatibility:
<a href="https://man.openbsd.org/scp.1">scp(1)</a> when using
the SFTP protocol no longer requires this finicky and brittle quoting,
and attempts to use it may cause transfers to fail. We consider the
removal of the need for double-quoting shell characters in file names
to be a benefit and do not intend to introduce bug-compatibility for
legacy scp/rcp in <a href="https://man.openbsd.org/scp.1">scp(1)</a>
when using the SFTP protocol.<br>
Another area of potential incompatibility relates to the use of remote
paths relative to other user's home directories, for example -
"scp host:~user/file /tmp". The SFTP protocol has no native way to
expand a ~user path. However,
<a href="https://man.openbsd.org/sftp-server.8">sftp-server(8)</a>
in OpenSSH 8.7 and later support a protocol extension
"expand-path@openssh.com" to support this.<br>
In case of incompatibility, the
<a href="https://man.openbsd.org/scp.1">scp(1)</a> client may be instructed to use
the legacy scp/rcp using the -O flag.
</ul>
<li>New features
<ul>
<!-- OpenSSH 8.9 -->
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
<a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
<a href="https://man.openbsd.org/ssh-add.1">ssh-add(1)</a>,
<a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
add a system for restricting forwarding and use of keys added to
<a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>
A detailed description of the feature is available at
https://www.openssh.com/agent-restrict.html and the protocol
extensions are documented in the
<a href="https://cvsweb.openbsd.org/src/usr.bin/ssh/PROTOCOL?annotate=OPENBSD_7_1"
>PROTOCOL</a> and
<a href="https://cvsweb.openbsd.org/src/usr.bin/ssh/PROTOCOL.agent?annotate=OPENBSD_7_1"
>PROTOCOL.agent</a> files in the source release.
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
<a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
add the sntrup761x25519-sha512@openssh.com hybrid
ECDH/x25519 + Streamlined NTRU Prime post-quantum KEX to the
default KEXAlgorithms list (after the ECDH methods but before the
prime-group DH ones).
<li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
when downloading resident keys from a FIDO token,
pass back the user ID that was used when the key was created and
append it to the filename the key is written to (if it is not the
default). Avoids keys being clobbered if the user created multiple
resident keys with the same application string but different user
IDs.
<li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>,
<a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
<a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
better handling for FIDO keys
on tokens that provide user verification (UV) on the device itself,
including biometric keys, avoiding unnecessary PIN prompts.
<li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>: add "ssh-keygen -Y match-principals" operation to
perform matching of principals names against an allowed signers
file. To be used towards a TOFU model for SSH signatures in git.
<li><a href="https://man.openbsd.org/ssh-add.1">ssh-add(1)</a>,
<a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
allow pin-required FIDO keys to be added
to <a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>.
$SSH_ASKPASS will be used to request the PIN at authentication time.
<li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
allow selection of hash at sshsig signing time
(either sha512 (default) or sha256).
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
<a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
read network data directly to the packet input
buffer instead of indirectly via a small stack buffer. Provides a
modest performance improvement.
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
<a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
read data directly to the channel input buffer,
providing a similar modest performance improvement.
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
extend the PubkeyAuthentication configuration directive to
accept yes|no|unbound|host-bound to allow control over one of the
protocol extensions used to implement agent-restricted keys.
<!-- OpenSSH 9.0 -->
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
<a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
use the hybrid Streamlined NTRU Prime + x25519 key
exchange method by default ("sntrup761x25519-sha512@openssh.com").
The NTRU algorithm is believed to resist attacks enabled by future
quantum computers and is paired with the X25519 ECDH key exchange
(the previous default) as a backstop against any weaknesses in
NTRU Prime that may be discovered in the future. The combination
ensures that the hybrid exchange offers at least as good security
as the status quo.<br>
We are making this change now (i.e. ahead of cryptographically-
relevant quantum computers) to prevent "capture now, decrypt
later" attacks where an adversary who can record and store SSH
session ciphertext would be able to decrypt it once a sufficiently
advanced quantum computer is available.
<li><a href="https://man.openbsd.org/sftp-server.8">sftp-server(8)</a>:
support the "copy-data" extension to allow server-
side copying of files/data, following the design in
draft-ietf-secsh-filexfer-extensions-00.
<li><a href="https://man.openbsd.org/sftp.1">sftp(1)</a>:
add a "cp" command to allow the sftp client to perform
server-side file copies.
</ul>
<li>Bugfixes
<ul>
<!-- OpenSSH 8.9 -->
<li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
document that CASignatureAlgorithms, ExposeAuthInfo and
PubkeyAuthOptions can be used in a Match block.
<li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
fix possible string truncation when constructing paths to
.rhosts/.shosts files with very long user home directory names.
<li>ssh-keysign(1): unbreak for KEX algorithms that use SHA384/512
exchange hashes
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
don't put the TTY into raw mode when SessionType=none,
avoids ^C being unable to kill such a session.
<li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
fix some corner-case bugs in SFTP-mode handling of
~-prefixed paths.
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
unbreak hostbased auth using RSA keys. Allow
<a href="https://man.openbsd.org/ssh.1">ssh(1)</a> to
select RSA keys when only RSA/SHA2 signature algorithms are
configured (this is the default case). Previously RSA keys were
not being considered in the default case.
<li>ssh-keysign(1): make ssh-keysign use the requested signature
algorithm and not the default for the key type. Part of unbreaking
hostbased auth for RSA/SHA2 keys.
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
stricter UpdateHostkey signature verification logic on
the client- side. Require RSA/SHA2 signatures for RSA hostkeys
except when RSA/SHA1 was explicitly negotiated during initial
KEX
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
<a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
fix signature algorithm selection logic for
UpdateHostkeys on the server side. The previous code tried to
prefer RSA/SHA2 for hostkey proofs of RSA keys, but missed some
cases. This will use RSA/SHA2 signatures for RSA keys if the
client proposed these algorithms in initial KEX.
<li>All: convert all uses of
<a href="https://man.openbsd.org/select.2">select(2)</a>/
<a href="https://man.openbsd.org/pselect.2">pselect(2)</a> to
<a href="https://man.openbsd.org/poll.2">poll(2)</a>/
<a href="https://man.openbsd.org/ppoll.2">ppoll(2)</a>.
This includes the mainloops in
<a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
<a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
<a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>
and <a href="https://man.openbsd.org/sftp-server.8">sftp-server(8)</a>,
as well as the <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>
listen loop and all other FD read/writability checks.
<li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
the "-Y find-principals" command was verifying key
validity when using ca certs but not with simple key lifetimes
within the allowed signers file.
<li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
make sshsig verify-time argument parsing optional
<li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
fix truncation in rhosts/shosts path construction.
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
<a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
avoid xmalloc(0) for PKCS#11 keyid for ECDSA
keys (we already did this for RSA keys). Avoids fatal errors for
PKCS#11 libraries that return empty keyid, e.g. Microchip ATECC608B
"cryptoauthlib"
<li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
<a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
improve the testing of credentials against
inserted FIDO: ask the token whether a particular key belongs to
it in cases where the token supports on-token user-verification
(e.g. biometrics) rather than just assuming that it will accept it.<br>
Will reduce spurious "Confirm user presence" notifications for key

the other directives contained in it,
even when the manpath is overridden by other means.
<li>Fixed a memory leak in
<a href="https://man.openbsd.org/man.1">man(1)</a>
that mattered when many names were given on the command line.
<li>Fixed a small memory leak in the
<a href="https://man.openbsd.org/roff.7">roff(7)</a> parser
that occurred each time a user-defined macro was called.
<li>Fixed the width of the <code>\h</code> (horizontal motion)
<a href="https://man.openbsd.org/roff.7">roff(7)</a>
escape sequence in the PostScript and PDF output modes.

<section id=quickinstall>
<p>
Quick installer information for people familiar with OpenBSD, and the use of
the "<a href="https://man.openbsd.org/disklabel.8">disklabel</a> -E" command.
If you are at all confused when installing OpenBSD, read the relevant
INSTALL.* file as listed above!
<h3>OpenBSD/alpha:</h3>
<p>
If your machine can boot from CD, you can write <i>install71.iso</i> or
<i>cd71.iso</i> to a CD and boot from it.
Refer to INSTALL.alpha for more details.
<h3>OpenBSD/amd64:</h3>
<p>
If your machine can boot from CD, you can write <i>install71.iso</i> or
<i>cd71.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>install71.img</i> or
<i>miniroot71.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.amd64 document.
<p>
If you are planning to dual boot OpenBSD with another OS, you will need to
read INSTALL.amd64.
<h3>OpenBSD/arm64:</h3>
<p>
Write <i>install71.img</i> or <i>miniroot71.img</i> to a disk and boot from it
after connecting to the serial console. Refer to INSTALL.arm64 for more
details.
<h3>OpenBSD/armv7:</h3>
<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>install71.iso</i> or
<i>cd71.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>install71.img</i> or
<i>miniroot71.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>miniroot71.img</i> to the start of the CF
or disk, and boot normally.
<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
/7.1/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>install71.img</i> or <i>miniroot71.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>install71.img</i> or <i>miniroot71.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>floppy71.img</i> or <i>floppyB71.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>miniroot71.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.

<h3>How to upgrade</h3>
<p>
If you already have an OpenBSD 7.0 system, and do not want to reinstall,
upgrade instructions and advice can be found in the
<a href="faq/upgrade71.html">Upgrade Guide</a>.
</section>
<hr>
<section id=sourcecode>
<h3>Notes about the source code</h3>
<p>
<code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
This file contains everything you need except for the kernel sources,
which are in a separate archive.
To extract:
<blockquote><pre>
# <kbd>mkdir -p /usr/src</kbd>
# <kbd>cd /usr/src</kbd>
# <kbd>tar xvfz /tmp/src.tar.gz</kbd>
</pre></blockquote>
<p>
<code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
This file contains all the kernel sources you need to rebuild kernels.
To extract:
<blockquote><pre>
# <kbd>mkdir -p /usr/src/sys</kbd>
# <kbd>cd /usr/src</kbd>
# <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
</pre></blockquote>
<p>
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 <a href="anoncvs.html">here</a>.
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.
</section>
<hr>
<section id=ports>
<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_1</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 7.1 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.
