1.1 deraadt 195: </ul>
196: <p>
197:
198: <li>Generic network stack improvements:
199: <ul>
1.63 jsing 200: <li>Incoming and forwarded IP packets are now processed without
201: KERNEL_LOCK, resulting in better performances and reduced latency.
202: <li>The kernel no longer handles IPv6 Stateless Address
203: Autoconfiguration (RFC 4862), allowing cleanup and simplification
204: of the IPv6 network stack.
205: <li>The kernel sends IPv6 router solicitations for link local addresses
206: with a link local source address.
207: <li>FQ-CoDel algorithm has been implemented for use with <a
208: href="https://man.openbsd.org/pf.conf#QUEUEING">pf(4) queueing</a>.
209: <li>Improved IPv6 checks for IPsec policies and made them consistent
1.31 bluhm 210: with IPv4.
1.63 jsing 211: <li>Refactored local IP delivery to process IPsec packets in a flow and
212: avoid enqueueing a second time.
1.31 bluhm 213: <li><a href="https://man.openbsd.org/pf.4">pf(4)</a>
1.63 jsing 214: now inspects AH packets and matches on the inner protocol.
1.31 bluhm 215: This makes IPv4 authentication headers work like IPv6.
216: <li>The length of extension header chains in pf(4) is limited.
1.63 jsing 217: This prevents spending excessive CPU time on crafted packets.
218: <li>Block IPv6 packets in
219: <a href="https://man.openbsd.org/pf.4">pf(4)</a>
220: that have a hop-by-hop options header or a destination options header.
221: Such packets can be passed by adding "allow-opts" to the rule.
222: This makes IPv6 option handling consistent with IPv4.
1.38 jca 223: <li>If the IPv4 ID gets reused too fast, pf(4) fragment reassembly
1.31 bluhm 224: uses a smarter strategy to drop packets.
1.63 jsing 225: <li>Enabled the use of per-CPU caches in the network packet allocators.
1.1 deraadt 226: </ul>
227: <p>
228:

1.1 deraadt 244: </ul>
245: <p>
246:
247: <li>Routing daemons and other userland network improvements:
248: <ul>
1.63 jsing 249: <li>A new daemon, <a
250: href="https://man.openbsd.org/slaacd.8">slaacd(8)</a> handles IPv6
251: Stateless Address Autoconfiguration (RFC 4862).
252: <li><a href="https://man.openbsd.org/rtadvd.8">rtadvd(8)</a> now supports
253: "Reducing Energy Consumption of Router Advertisements" (RFC 7772).
1.37 jca 254: <li><a href="https://man.openbsd.org/rtadvd.8">rtadvd(8)</a> has
1.66 rob 255: been fixed to quickly handle IPv6 prefix changes on the system.
1.31 bluhm 256: <li><a href="https://man.openbsd.org/ipsecctl.8">ipsecctl(8)</a>
1.63 jsing 257: can now show SA bundles and the "bundle" keyword allows them to be
258: explicitly created. This avoids confusion as they were previously
259: used implicitly.
1.31 bluhm 260: <li><a href="https://man.openbsd.org/nc.1">nc(1)</a>
1.63 jsing 261: now has a <tt>-W recvlimit</tt> option to terminate netcat after
262: receiving the specified number of packets. This allows for a UDP
263: request to be sent, a reply to be received and the result checked on
264: the command line.
1.58 jsing 265: <li><a href="https://man.openbsd.org/nc.1">nc(1)</a>
1.63 jsing 266: now has a <tt>-Z</tt> option, allowing the peer certificate and chain to be
1.58 jsing 267: saved to a file in PEM format.
1.63 jsing 268: <li>A new <tt>-T tlscompat</tt> option was added to
1.58 jsing 269: <a href="https://man.openbsd.org/nc.1">nc(1)</a>, which enables the use
270: of all TLS protocols and libtls "compat" ciphers.
1.63 jsing 271: <li>Various races have been fixed in
272: <a href="https://man.openbsd.org/relayd.8">relayd(8)</a>,
1.31 bluhm 273: expecially in HTTP chunked mode.
1.63 jsing 274: <li><a href="https://man.openbsd.org/ndp.8">ndp(8)</a> now shows the
275: relevant NDP information when run in a non-default routing
276: domain.
1.40 jca 277: <li><a href="https://man.openbsd.org/ifstated.8">ifstated(8)</a> now
1.63 jsing 278: copes with interface departures/arrivals.
1.51 benno 279: <li><a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a> can now
1.63 jsing 280: be started multiple times in different
281: <a href="https://man.openbsd.org/rdomain.4">routing domains</a>,
282: this provides virtual router functionality.
1.1 deraadt 283: </ul>
284: <p>
285:
286: <li>Security improvements:
287: <ul>
1.9 otto 288: <li>A new function

291: <li>Double free detection has been improved when the F
292: <a href="https://man.openbsd.org/malloc.3">malloc(3)</a> option is used.
293: The existing S option now includes F.
1.24 anton 294: <li>The <a href="https://man.openbsd.org/tty.4#TIOCSTI">TIOCSTI</a>
1.19 deraadt 295: tty ioctl has been removed. The I/O-loops in the last two consumers
1.24 anton 296: <a href="https://man.openbsd.org/csh.1">csh(1)</a> and
297: <a href="https://man.openbsd.org/mail.1">mail(1)</a>
1.19 deraadt 298: were rewritten to cope with the removal.
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
1.53 deraadt 305: kernel for each boot. /bsd is now non-readable to users, to try to
306: keep the secret.
1.29 brynet 307: <li>Like with libc previously,
308: <a href="https://man.openbsd.org/rc.8">rc(8)</a> re-links libcrypto on
309: startup, placing the objects in a random order.
310: <li>In addition to libcrypto, to deter code reuse exploits,
311: <a href="https://man.openbsd.org/rc.8">rc(8)</a> re-links
312: <a href="https://man.openbsd.org/ld.so.1">ld.so</a> on
313: startup, placing the objects in a random order.
1.31 bluhm 314: <li>If process accounting is activated with
315: <a href="https://man.openbsd.org/accton.8">accton(8)</a>,
316: the daily mail shows pledge violations and program crashes.
317: <a href="https://man.openbsd.org/lastcomm.8">lastcomm(8)</a>
318: uses the flags P and T for such processes.
1.34 brynet 319: <li><a href="https://man.openbsd.org/pflogd.8">pflogd(8)</a> uses the
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>
324: uses <a href="https://man.openbsd.org/pledge.2">pledge(2)</a>.
325: <li><a href="https://man.openbsd.org/snmpd.8">snmpd(8)</a> and
326: <a href="https://man.openbsd.org/snmpd.8">snmpctl(8)</a> now use
327: <a href="https://man.openbsd.org/pledge.2">pledge(2)</a>.
1.45 tb 328: <li>Tighter pledge for <a href="https://man.openbsd.org/at.1">at(1)</a>.
329: <li>Fixed and simplified pledge logic for
330: <a href="https://man.openbsd.org/nc.1">nc(1)</a>.
1.53 deraadt 331: <li>More application of recallocarray(3) in userland, and tracked sizes
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
336: with security.
337: <li>For instance, cope with clang(1)'s assumption that static or const
338: objects placed in unknown sections (such as .openbsd.randomdata)

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

642: <li>Cleaned up and simplified server key exchange EC point handling.
643: <li>Removed inconsistent IPv6 handling from BIO_get_accept_socket(),

645: <li>Added definitions for three OIDs used in EV certificates.
646: <li>Relaxed SNI validation to allow non-RFC-compliant clients using literal
647: IP addresses with SNI to connect to a libtls-based TLS server.
648: <li>Added tls_peer_cert_chain_pem() to libtls, useful in private certificate
649: validation callbacks such as those in relayd.
650: <li>Converted explicit clear/free sequences to use
651: <a href="https://man.openbsd.org/freezero.3">freezero(3)</a>.
652: <li>Fixed the

660: functions.
661: <li>Imported HKDF (HMAC Key Derivation Function) from BoringSSL.
662: <li>Provided a
663: <a href="https://man.openbsd.org/tls_unload_file.3">tls_unload_file(3)</a>

670: <a href="https://man.openbsd.org/tls_configure.3">tls_configure(3)</a>
671: call, simplifying lifetime tracking for the application.
672: <li>Dropped cipher suites using DSS authentication.
673: <li>Removed support for DSS/DSA from libssl.
674: <li>Distinguish between self-issued certificates and self-signed
675: certificates. The certificate verification code has special cases
676: for self-signed certificates and without this change, self-issued
677: certificates (which it seems are common place with
678: openvpn/easyrsa) were also being included in this category.
679: <li>Added a new TLS extension handling framework and converted all

1.60 jsing 695: workaround for an old bug in F5's TLS termination.
1.65 rob 696: <li>Added ability to clamp notafter values in certificates for systems
1.58 jsing 697: with 32-bit time_t. This is necessary to conform to RFC 5280 4.1.2.5.
