1.1 deraadt 131: </ul>
132: <p>
133:
134: <li>Generic network stack improvements:
135: <ul>
1.20 mpi 136: <li> Incoming and forwarded IP packets are now processed without
137: KERNEL_LOCK, resulting in better performances and reduced latency
1.4 florian 138: <li> The kernel no longer handles IPv6 Stateless Address
139: Autoconfiguration (RFC 4862), allowing cleanup and simplification
140: of the IPv6 network stack.
141: <li> The kernel sends IPv6 router solicitations for link local addresses
142: with a link local source address.
1.16 mikeb 143: <li> FQ-CoDel algorithm has been implemented for use with <a
144: href="https://man.openbsd.org/pf.conf#QUEUEING">pf(4) queueing</a>.

146: with IPv4.
147: <li>Refactor local IP delivery to process IPsec packets in a flow.
148: Avoid that they are enqueued a second time.
149: <li><a href="https://man.openbsd.org/pf.4">pf(4)</a>
150: looks into AH packets and matches on the inner protocol.
151: This makes IPv4 authentication headers work like IPv6.
152: <li>The length of extension header chains in pf(4) is limited.
153: This prevents spending excessive cpu time on crafted packets.
154: <li>Block IPv6 packets in pf(4) that have hop-by-hop options
155: header or destination options header.
156: Such packets can be passed by adding "allow-opts" to the
157: rule.
158: So IPv6 options are handled like their counterpart in IPv4
159: now.
1.38 jca 160: <li>If the IPv4 ID gets reused too fast, pf(4) fragment reassembly
1.31 bluhm 161: uses a smarter strategy to drop packets.
1.52 dlg 162: <li>Enable the use of per-CPU caches on the network packet allocators
1.1 deraadt 163: </ul>
164: <p>
165:

1.31 bluhm 182: href="https://man.openbsd.org/slaacd.8">slaacd(8)</a> handles IPv6
1.4 florian 183: Stateless Address Autoconfiguration (RFC 4862).
1.31 bluhm 184: <li> <a href="https://man.openbsd.org/rtadvd.8">rtadvd(8)</a> now supports
1.4 florian 185: "Reducing Energy Consumption of Router Advertisements" (RFC 7772).

187: been fixed to quickly handle IPv6 prefixes changes on the system.
1.31 bluhm 188: <li><a href="https://man.openbsd.org/ipsecctl.8">ipsecctl(8)</a>
189: can show SA bundles now.
190: The keyword "bundle" allows to create them explicitly.
191: This avoids confusion as they were used implicitly before.
192: <li><a href="https://man.openbsd.org/nc.1">nc(1)</a>
193: has got the option -W "recvlimit" to terminate netcat after
194: receiving a number of packets.
195: This allows to send a UDP request, receive a reply and check
196: the result on the command line.
1.58 jsing 197: <li><a href="https://man.openbsd.org/nc.1">nc(1)</a>
198: now has a -Z option, allowing the peer certificate and chain to be
199: saved to a file in PEM format.
200: <li>A new "-T tlscompat" option was added to
201: <a href="https://man.openbsd.org/nc.1">nc(1)</a>, which enables the use
202: of all TLS protocols and libtls "compat" ciphers.
1.31 bluhm 203: <li>Fix a bunch of races in
204: <a href="https://man.openbsd.org/relayd.8">relayd(8)</a>

207: relevant NDP information when run in a non-default routing
208: domain.
1.40 jca 209: <li><a href="https://man.openbsd.org/ifstated.8">ifstated(8)</a> now
210: copes with interface departures/arrivals.
1.51 benno 211: <li><a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a> can now
212: be started multiple times in different
213: <a href="https://man.openbsd.org/rdomain.4">routing domains</a>,
214: this provides virtual router functionality.
1.1 deraadt 215: </ul>
216: <p>
217:
218: <li>Security improvements:
219: <ul>
1.9 otto 220: <li>A new function

229: <a href="https://man.openbsd.org/mail.1">mail(1)</a>
1.19 deraadt 230: were rewritten to cope with the removal.
1.29 brynet 231: <li>Trapsleds, a new mitigation that significantly reduces the amount of
1.53 deraadt 232: nops in the instruction stream, replacing them with trap instructions
233: or jump-over-trap sequences, thereby requiring greater accuracy for
234: targetting potential gadgets.
1.29 brynet 235: <li>Kernel Address Randomized Link (KARL), a new "link-kit" allows the .o
236: files of the kernel to be relinked in a random order, creating a unique
1.53 deraadt 237: kernel for each boot. /bsd is now non-readable to users, to try to
238: keep the secret.
1.29 brynet 239: <li>Like with libc previously,
240: <a href="https://man.openbsd.org/rc.8">rc(8)</a> re-links libcrypto on
241: startup, placing the objects in a random order.
242: <li>In addition to libcrypto, to deter code reuse exploits,
243: <a href="https://man.openbsd.org/rc.8">rc(8)</a> re-links
244: <a href="https://man.openbsd.org/ld.so.1">ld.so</a> on
245: startup, placing the objects in a random order.
1.31 bluhm 246: <li>If process accounting is activated with
247: <a href="https://man.openbsd.org/accton.8">accton(8)</a>,
248: the daily mail shows pledge violations and program crashes.
249: <a href="https://man.openbsd.org/lastcomm.8">lastcomm(8)</a>
250: uses the flags P and T for such processes.
1.34 brynet 251: <li><a href="https://man.openbsd.org/pflogd.8">pflogd(8)</a> uses the
252: fork+exec model.
253: <li><a href="https://man.openbsd.org/tcpdump.8">tcpdump(8)</a> uses the
254: fork+exec model.
1.39 jca 255: <li><a href="https://man.openbsd.org/ifstated.8">ifstated(8)</a>
256: uses <a href="https://man.openbsd.org/pledge.2">pledge(2)</a>.

1.45 tb 260: <li>Tighter pledge for <a href="https://man.openbsd.org/at.1">at(1)</a>.
261: <li>Fixed and simplified pledge logic for
262: <a href="https://man.openbsd.org/nc.1">nc(1)</a>.
1.53 deraadt 263: <li>More application of recallocarray(3) in userland, and tracked sizes
264: to free(9) in the kernel.
265: <li>Achieve higher levels of paranoia regarding structure packing, and
266: clear many kernel objects before passing to userland.
267: <li>Disable some optimizations in clang(1) due to incompatibility
268: with security.
269: <li>For instance, cope with clang(1)'s assumption that static or const
270: objects placed in unknown sections (such as .openbsd.randomdata)
271: are surely always 0, and therefore such memory accesses can be
272: optimized away..
273: <li>In kernel, randomly bias down the top-of-stack per kthread.

458: permitting creation of zero-length files.
1.1 deraadt 459: </ul>
460: <li>New/changed features:
461: <ul>
1.31 bluhm 462: <li>Add RemoteCommand option to specify a command in the
463: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>
464: config file instead of giving it on the client's command
465: line.
466: The feature allows to automate tasks using ssh config.
1.56 djm 467: <li>sshd(8): add ExposeAuthInfo option that enables writing details of
468: the authentication methods used (including public keys where
469: applicable) to a file that is exposed via a $SSH_USER_AUTH
470: environment variable in the subsequent session.
471: <li>ssh(1): add support for reverse dynamic forwarding. In this mode,
472: ssh will act as a SOCKS4/5 proxy and forward connections
473: to destinations requested by the remote SOCKS client. This mode
474: is requested using extended syntax for the -R and RemoteForward
475: options and, because it is implemented solely at the client,
476: does not require the server be updated to be supported.
477: <li>sshd(8): allow LogLevel directive in sshd_config Match blocks.
478: <li>ssh-keygen(1): allow inclusion of arbitrary string or flag
479: certificate extensions and critical options.`
480: <li>ssh-keygen(1): allow ssh-keygen to use a key held in ssh-agent as
481: a CA when signing certificates.
482: <li>ssh(1)/sshd(8): allow IPQoS=none in ssh/sshd to not set an explicit
483: ToS/DSCP value and just use the operating system default.
484: <li>ssh-add(1): added -q option to make ssh-add quiet on success.
485: <li>ssh(1): expand the StrictHostKeyChecking option with two new
486: settings. The first "accept-new" will automatically accept
487: hitherto-unseen keys but will refuse connections for changed or
488: invalid hostkeys. This is a safer subset of the current behaviour
489: of StrictHostKeyChecking=no. The second setting "off", is a synonym
490: for the current behaviour of StrictHostKeyChecking=no: accept new
491: host keys, and continue connection for hosts with incorrect
492: hostkeys. A future release will change the meaning of
493: StrictHostKeyChecking=no to the behaviour of "accept-new".
494: <li>ssh(1): add SyslogFacility option to ssh(1) matching the equivalent
495: option in sshd(8).
1.1 deraadt 496: </ul>
497: <li>The following significant bugs have been fixed in this release:
498: <ul>
1.56 djm 499: <li>ssh(1): use HostKeyAlias if specified instead of hostname for
500: matching host certificate principal names
501: <li>sftp(1): implement sorting for globbed ls.
502: <li>ssh(1): add a user@host prefix to client's "Permission denied"
503: messages, useful in particular when using "stacked" connections
504: (e.g. ssh -J) where it's not clear which host is denying.
505: <li>ssh(1): accept unknown EXT_INFO extension values that contain \0
506: characters. These are legal, but would previously cause fatal
507: connection errors if received.
508: <li>ssh(1)/sshd(8): repair compression statistics printed at
509: connection exit.
510: <li>sftp(1): print '?' instead of incorrect link count (that the
511: protocol doesn't provide) for remote listings.
512: <li>ssh(1): return failure rather than fatal() for more cases during
513: session multiplexing negotiations. Causes the session to fall back
514: to a non-mux connection if they occur.
515: <li>ssh(1): mention that the server may send debug messages to explain
516: public key authentication problems under some circumstances.
517: <li>Translate OpenSSL error codes to better report incorrect passphrase
518: errors when loading private keys.
519: <li>sshd(8): adjust compatibility patterns for WinSCP to correctly
520: identify versions that implement only the legacy DH group exchange
521: scheme.
522: <li>ssh(1): print the "Killed by signal 1" message only at LogLevel
523: verbose so that it is not shown at the default level; prevents it
524: from appearing during ssh -J and equivalent ProxyCommand configs.
525: <li>ssh-keygen(1): when generating all hostkeys (ssh-keygen -A), clobber
526: existing keys if they exist but are zero length. zero-length keys
527: could previously be made if ssh-keygen failed or was interrupted part
528: way through generating them.
529: <li>ssh(1): fix pledge(2) violation in the escape sequence "~&" used to
530: place the current session in the background.
531: <li>ssh-keyscan(1): avoid double-close() on file descriptors.
532: <li>sshd(8): avoid reliance on shared use of pointers shared between
533: monitor and child sshd processes.
534: <li>sshd_config(8): document available AuthenticationMethods.
535: <li>ssh(1): avoid truncation in some login prompts.
536: <li>ssh(1): make "--" before the hostname terminate argument processing
537: after the hostname too.
538: <li>ssh-keygen(1): switch from aes256-cbc to aes256-ctr for encrypting
539: new-style private keys. Fixes problems related to private key
540: handling for no-OpenSSL builds.
541: <li>ssh(1): warn and do not attempt to use keys when the public and
542: private halves do not match.
543: <li>sftp(1): don't print verbose error message when ssh disconnects
544: from under sftp.
545: <li>sshd(8): fix keepalive scheduling problem: activity on a forwarded
546: port from preventing the keepalive from being sent.
547: <li>sshd(8): when started without root privileges, don't require the
548: privilege separation user or path to exist. Makes running the
549: regression tests easier without touching the filesystem.
550: <li>Make integrity.sh regression tests more robust against timeouts.
551: <li>ssh(1)/sshd(8): correctness fix for channels implementation: accept
552: channel IDs greater than 0x7FFFFFFF.

561: <li>Cleaned up and simplified server key exchange EC point handling.
562: <li>Removed inconsistent IPv6 handling from BIO_get_accept_socket(),
563: simplified BIO_get_host_ip() and BIO_accept().
564: <li>Added definitions for three OIDs used in EV certificates.
565: <li>Relaxed SNI validation to allow non-RFC-compliant clients using literal
566: IP addresses with SNI to connect to a libtls-based TLS server.
567: <li>Added tls_peer_cert_chain_pem() to libtls, useful in private certificate
568: validation callbacks such as those in relayd.
569: <li>Converted explicit clear/free sequences to use
570: <a href="https://man.openbsd.org/freezero.3">freezero(3)</a>.
571: <li>Fixed the

573: ca command so that is generates certificates with RFC 5280-conformant time.
574: <li>Added
575: <a href="https://man.openbsd.org/ASN1_TIME_set_tm.3">ASN1_TIME_set_tm(3)</a>
576: to set an ASN.1 time from a struct tm *.

579: functions.
580: <li>Imported HKDF (HMAC Key Derivation Function) from BoringSSL.
581: <li>Provided a
582: <a href="https://man.openbsd.org/tls_unload_file.3">tls_unload_file(3)</a>
583: function that frees the memory returned from a
584: <a href="https://man.openbsd.org/tls_load_file.3">tls_load_file(3)</a>
585: call, ensuring that it the contents become inaccessible.
586: <li>Implemented reference counting for libtls tls_config, allowing
587: <a href="https://man.openbsd.org/tls_config_free.3">tls_config_free(3)</a>
588: to be called as soon as it has been passed to the final
589: <a href="https://man.openbsd.org/tls_configure.3">tls_configure(3)</a>
590: call, simplifying lifetime tracking for the application.
591: <li>Dropped cipher suites using DSS authentication.
592: <li>Removed support for DSS/DSA from libssl.
593: <li>Distinguish between self-issued certificates and self-signed
594: certificates. The certificate verification code has special cases
595: for self-signed certificates and without this change, self-issued
596: certificates (which it seems are common place with
597: openvpn/easyrsa) were also being included in this category.
598: <li>Added a new TLS extension handling framework and converted all
599: TLS extensions to use it.
600: <li>Improved and added many new manpages. Updated
601: <a href="https://man.openbsd.org/SSL_CTX_check_private_key.3">SSL_{CTX_,}check_private_key(3)</a>
602: manpages with additional cautions regarding their use.
603: <li>Cleaned up and simplified EC key/curve configuration handling.
604: <li>Added
605: <a href="https://man.openbsd.org/tls_config_set_ecdhecurves.3">tls_config_set_ecdhecurves(3)</a>
606: to libtls, which allows the names of the elliptical curves that may
607: be used during client and server key exchange to be specified.
608: <li>Converted more code paths to use CBB/CBS.
609: <li>Removed NPN support - NPN was never standardised and the last draft
610: expired in October 2012.
611: <li>Removed SSL_OP_CRYPTOPRO_TLSEXT_BUG workaround for old/broken
612: CryptoPro clients.
613: <li>Removed support for the TLS padding extension, which was added as a
614: workaround for an old bug in F5's TLS termintation.
615: <li>Added ability to clamp notafter valies in certificates for systems
616: with 32-bit time_t. This is necessary to conform to RFC 5280 4.1.2.5.
617: <li>Removed the original (pre-IETF) chacha20-poly1305 cipher suites.
618: <li>Reclassified ECDHE-RSA-DES-CBC3-SHA from HIGH to MEDIUM.
619: <li>Provide a useful error with libtls if there are no OCSP URLs in a
620: peer certificate.
621: <li>Keep track of which keypair is in use by a TLS context, fixing a bug
622: where a TLS server with SNI would only return the OCSP staple for the
623: default keypair.
624: <li>If
625: <a href="https://man.openbsd.org/tls_config_parse_protocols.3">tls_config_parse_protocols(3)</a>
626: is called with a NULL pointer it now

1051:
1052: [Of course, you must replace the server name here with a nearby anoncvs
1053: server.]
1054: <p>
1055: Note that most ports are available as packages on our mirrors. Updated
1056: ports for the 6.2 release will be made available if problems arise.
