1.29 brynet 299: <li>Trapsleds, a new mitigation that significantly reduces the amount of
1.53 deraadt 300: nops in the instruction stream, replacing them with trap instructions
301: or jump-over-trap sequences, thereby requiring greater accuracy for
302: targetting potential gadgets.
1.29 brynet 303: <li>Kernel Address Randomized Link (KARL), a new "link-kit" allows the .o
304: files of the kernel to be relinked in a random order, creating a unique

320: fork+exec model.
321: <li><a href="https://man.openbsd.org/tcpdump.8">tcpdump(8)</a> uses the
322: fork+exec model.
1.39 jca 323: <li><a href="https://man.openbsd.org/ifstated.8">ifstated(8)</a>

332: to free(9) in the kernel.
333: <li>Achieve higher levels of paranoia regarding structure packing, and
334: clear many kernel objects before passing to userland.
335: <li>Disable some optimizations in clang(1) due to incompatibility

534: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>
535: config file instead of giving it on the client's command
536: line.
537: The feature allows to automate tasks using ssh config.
1.56 djm 538: <li>sshd(8): add ExposeAuthInfo option that enables writing details of
539: the authentication methods used (including public keys where
540: applicable) to a file that is exposed via a $SSH_USER_AUTH
541: environment variable in the subsequent session.
542: <li>ssh(1): add support for reverse dynamic forwarding. In this mode,
543: ssh will act as a SOCKS4/5 proxy and forward connections
544: to destinations requested by the remote SOCKS client. This mode
545: is requested using extended syntax for the -R and RemoteForward
546: options and, because it is implemented solely at the client,
547: does not require the server be updated to be supported.
548: <li>sshd(8): allow LogLevel directive in sshd_config Match blocks.
549: <li>ssh-keygen(1): allow inclusion of arbitrary string or flag
550: certificate extensions and critical options.`
551: <li>ssh-keygen(1): allow ssh-keygen to use a key held in ssh-agent as
552: a CA when signing certificates.
553: <li>ssh(1)/sshd(8): allow IPQoS=none in ssh/sshd to not set an explicit
554: ToS/DSCP value and just use the operating system default.
555: <li>ssh-add(1): added -q option to make ssh-add quiet on success.
556: <li>ssh(1): expand the StrictHostKeyChecking option with two new
557: settings. The first "accept-new" will automatically accept
558: hitherto-unseen keys but will refuse connections for changed or
559: invalid hostkeys. This is a safer subset of the current behaviour
560: of StrictHostKeyChecking=no. The second setting "off", is a synonym
561: for the current behaviour of StrictHostKeyChecking=no: accept new
562: host keys, and continue connection for hosts with incorrect
563: hostkeys. A future release will change the meaning of
564: StrictHostKeyChecking=no to the behaviour of "accept-new".
565: <li>ssh(1): add SyslogFacility option to ssh(1) matching the equivalent
566: option in sshd(8).
1.1 deraadt 567: </ul>
568: <li>The following significant bugs have been fixed in this release:
569: <ul>
1.56 djm 570: <li>ssh(1): use HostKeyAlias if specified instead of hostname for
571: matching host certificate principal names
572: <li>sftp(1): implement sorting for globbed ls.
573: <li>ssh(1): add a user@host prefix to client's "Permission denied"
574: messages, useful in particular when using "stacked" connections
575: (e.g. ssh -J) where it's not clear which host is denying.
576: <li>ssh(1): accept unknown EXT_INFO extension values that contain \0
577: characters. These are legal, but would previously cause fatal
578: connection errors if received.
579: <li>ssh(1)/sshd(8): repair compression statistics printed at
580: connection exit.
581: <li>sftp(1): print '?' instead of incorrect link count (that the
582: protocol doesn't provide) for remote listings.
583: <li>ssh(1): return failure rather than fatal() for more cases during
584: session multiplexing negotiations. Causes the session to fall back
585: to a non-mux connection if they occur.
586: <li>ssh(1): mention that the server may send debug messages to explain
587: public key authentication problems under some circumstances.
588: <li>Translate OpenSSL error codes to better report incorrect passphrase
589: errors when loading private keys.
590: <li>sshd(8): adjust compatibility patterns for WinSCP to correctly
591: identify versions that implement only the legacy DH group exchange
592: scheme.
593: <li>ssh(1): print the "Killed by signal 1" message only at LogLevel
594: verbose so that it is not shown at the default level; prevents it
595: from appearing during ssh -J and equivalent ProxyCommand configs.
596: <li>ssh-keygen(1): when generating all hostkeys (ssh-keygen -A), clobber
597: existing keys if they exist but are zero length. zero-length keys
598: could previously be made if ssh-keygen failed or was interrupted part
599: way through generating them.
600: <li>ssh(1): fix pledge(2) violation in the escape sequence "~&" used to
601: place the current session in the background.
602: <li>ssh-keyscan(1): avoid double-close() on file descriptors.
603: <li>sshd(8): avoid reliance on shared use of pointers shared between
604: monitor and child sshd processes.
605: <li>sshd_config(8): document available AuthenticationMethods.
606: <li>ssh(1): avoid truncation in some login prompts.
607: <li>ssh(1): make "--" before the hostname terminate argument processing
608: after the hostname too.
609: <li>ssh-keygen(1): switch from aes256-cbc to aes256-ctr for encrypting
610: new-style private keys. Fixes problems related to private key
611: handling for no-OpenSSL builds.
612: <li>ssh(1): warn and do not attempt to use keys when the public and
613: private halves do not match.
614: <li>sftp(1): don't print verbose error message when ssh disconnects
615: from under sftp.
616: <li>sshd(8): fix keepalive scheduling problem: activity on a forwarded
617: port from preventing the keepalive from being sent.
618: <li>sshd(8): when started without root privileges, don't require the
619: privilege separation user or path to exist. Makes running the
620: regression tests easier without touching the filesystem.
621: <li>Make integrity.sh regression tests more robust against timeouts.
622: <li>ssh(1)/sshd(8): correctness fix for channels implementation: accept
623: channel IDs greater than 0x7FFFFFFF.

634: CRL checking is enabled and required for the full certificate chain.
1.58 jsing 635: <li>Reworked TLS certificate name verification code to more strictly
636: follow RFC 6125.
637: <li>Cleaned up and simplified server key exchange EC point handling.
638: <li>Removed inconsistent IPv6 handling from BIO_get_accept_socket(),
639: simplified BIO_get_host_ip() and BIO_accept().
640: <li>Added definitions for three OIDs used in EV certificates.
641: <li>Relaxed SNI validation to allow non-RFC-compliant clients using literal
642: IP addresses with SNI to connect to a libtls-based TLS server.
643: <li>Added tls_peer_cert_chain_pem() to libtls, useful in private certificate
644: validation callbacks such as those in relayd.
645: <li>Converted explicit clear/free sequences to use
646: <a href="https://man.openbsd.org/freezero.3">freezero(3)</a>.

655: functions.
656: <li>Imported HKDF (HMAC Key Derivation Function) from BoringSSL.
657: <li>Provided a
658: <a href="https://man.openbsd.org/tls_unload_file.3">tls_unload_file(3)</a>
659: function that frees the memory returned from a
660: <a href="https://man.openbsd.org/tls_load_file.3">tls_load_file(3)</a>
661: call, ensuring that it the contents become inaccessible.
662: <li>Implemented reference counting for libtls tls_config, allowing
663: <a href="https://man.openbsd.org/tls_config_free.3">tls_config_free(3)</a>
664: to be called as soon as it has been passed to the final

666: call, simplifying lifetime tracking for the application.
667: <li>Dropped cipher suites using DSS authentication.
668: <li>Removed support for DSS/DSA from libssl.
669: <li>Distinguish between self-issued certificates and self-signed
670: certificates. The certificate verification code has special cases
671: for self-signed certificates and without this change, self-issued
672: certificates (which it seems are common place with
673: openvpn/easyrsa) were also being included in this category.
674: <li>Added a new TLS extension handling framework and converted all
675: TLS extensions to use it.
676: <li>Improved and added many new manpages. Updated
677: <a href="https://man.openbsd.org/SSL_CTX_check_private_key.3">SSL_{CTX_,}check_private_key(3)</a>
678: manpages with additional cautions regarding their use.

683: be used during client and server key exchange to be specified.
684: <li>Converted more code paths to use CBB/CBS.
685: <li>Removed NPN support - NPN was never standardised and the last draft
686: expired in October 2012.
687: <li>Removed SSL_OP_CRYPTOPRO_TLSEXT_BUG workaround for old/broken
688: CryptoPro clients.
689: <li>Removed support for the TLS padding extension, which was added as a
1.60 jsing 690: workaround for an old bug in F5's TLS termination.
1.58 jsing 691: <li>Added ability to clamp notafter valies in certificates for systems
692: with 32-bit time_t. This is necessary to conform to RFC 5280 4.1.2.5.

1127:
1128: [Of course, you must replace the server name here with a nearby anoncvs
1129: server.]
1130: <p>
1131: Note that most ports are available as packages on our mirrors. Updated
1132: ports for the 6.2 release will be made available if problems arise.

1134: If you're interested in seeing a port added, would like to help out, or just
