<h3>Changes made between OpenBSD 5.9 and 6.0</h3>
<p>
<ul>
<!-- 2016-07-26 -->
<li>Unbreak <a href="https://man.openbsd.org/rsu.4">rsu(4)</a>.
<li>In <a href="https://man.openbsd.org/rtwn.4">rtwn(4)</a> and <a href="https://man.openbsd.org/urtwn.4">urtwn(4)</a>, fix byteswap errors. This repairs <a href="https://man.openbsd.org/urtwn.4">urtwn(4)</a> on macppc.
<!-- 2016-07-25 -->
<li>In mesa, disable the code that allocates W|X memory.
<li>Disable tmpfs.
<li>In <a href="https://man.openbsd.org/rarpd.8">rarpd(8)</a>, avoid a hang when the receive buffer of a route socket becomes full.
<li>In <a href="https://man.openbsd.org/newfs.8">newfs(8)</a>, revert the change to scale the default "density" value to create the same number of inodes.
<li>In <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>, initialize the log subsytem in the SE like it is done in the RDE. This avoids all logging from going to /dev/null.
<li>When closing <a href="https://man.openbsd.org/bpf.4">bpf(4)</a> devices, ensure the minor number becomes free for reuse by the device cloning code. This fixes a panic.
<li>In <a href="https://man.openbsd.org/perl.1">perl(1)</a>, patch CVE-2016-1238.
<!-- 2016-07-24 -->
<li>In <a href="https://man.openbsd.org/tcpdump.8">tcpdump(8)</a>, only <a href="https://man.openbsd.org/chroot.2">chroot(2)</a> when run as root.
<!-- 2016-07-23 -->
<li><strong>5.8 and 5.9 RELIABILITY FIX: When signaling an error to an HTTP relay client, the connection can be terminated prematurely, leading to a crash.</strong><br>A source code patch exists which remedies this problem for <a href="errata58.html#024_relayd">5.8</a> and <a href="errata59.html#021_relayd">5.9</a>.
<li>In the installer, back out the automatic <a href="https://man.openbsd.org/pkg.conf.5">pkg.conf(5)</a> installpath changes.
<li>In <a href="https://man.openbsd.org/dhclient.8">dhclient(8)</a>, back out the change that narrowed the BPF read filter rules so only packets sent to the interface's LLADDR pass. Some DHCP servers send frames to the ethernet broadcast address.
<li>In imxuart(4/armv7), re-create the i.MX6 console with the correct minor number on attach.
<li>Disable POOL_DEBUG.
<li>In <a href="https://man.openbsd.org/newfs.8">newfs(8)</a>, scale the default "density" value so that on 4K disks the same number of inodes are creates as on DEV_BSIZE devices.
<li>In <a href="https://man.openbsd.org/stty.1">stty(1)</a>, error out if the display and modify mode are combined on the command line. This avoids a <a href="https://man.openbsd.org/pledge.2">pledge(2)</a> violation.
<li><a href="https://man.openbsd.org/amd64/vmm.4">vmm(4/amd64)</a>, fix a few CPUID emulation issues.
<!-- 2016-07-22 -->
<li>In <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>, fix <a href="https://man.openbsd.org/pledge.2">pledge(2)</a> violation with the -f option.
<li>Attach <a href="https://man.openbsd.org/armv7/imx.4">imx(4/armv7)</a> on i.mx6 quad plus.
<li>In <a href="https://man.openbsd.org/dhclient.8">dhclient(8)</a>, actually DECLINE and delete unused offers.
<li>In <a href="https://man.openbsd.org/armv7/fec.4">fec(4/armv7)</a>, fallback to the known IRQ number on imx.6 if the fdt interrupts-extended property is missing or not the size that is expected.
<li>In <a href="https://man.openbsd.org/rtable.4">rtable(4)</a>, prevent an infinite recursion when deleting routes inside rtable_walk().
<li>Prevent NULL-pointer call for filesystems that don't provide vfs_sysctl in their vfsops structs.
<li>In <a href="https://man.openbsd.org/relayd.8">relayd(8)</a>, fix a crash when the connection is terminated prematurely.
<li>Fix a double <a href="https://man.openbsd.org/rtfree.9">rtfree(9)</a> triggered when IPSEC inserts a more specific route because of PMTU.
<!-- 2016-07-21 -->
<li>In <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
everse the order in which -J/JumpHost proxies are visited to be more intuitive.
<li>In switchd(8), add basic support for OpenFlow 1.3 PACKET_IN+PACKET_OUT, no FLOW_MOD yet.
<li>In <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>, don't quit when the local addresses of a peer can't be figured out. Instead bring the session down.
<li>In <a href="https://man.openbsd.org/tcpbench.1">tcpbench(1)</a>, add AF_UNIX support and also make it possible to randomize the write size in the client.
<li>In <a href="https://man.openbsd.org/rtwn.4">rtwn(4)</a> and <a href="https://man.openbsd.org/urtwn.4">urtwn(4)</a>, respect the RTS threshold set by net80211.
<li>In <a href="https://man.openbsd.org/tcpdump.8">tcpdump(8)</a>, silently ignore <a href="https://man.openbsd.org/chroot.2">chroot(2)</a> setup failure, because <a href="https://man.openbsd.org/pledge.2">pledge(2)</a> provides an even better sandbox. This regain -r support.
<!-- 2016-07-20 -->
<li>In <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>, skip passwords longer than 1024 characters in length, so clients can't easily DoS sshd by sending very long passwords.
<li>Use <a href="https://man.openbsd.org/pledge.2">pledge(2)</a> in switchd(8) and switchctl(8).
<li>In <a href="https://man.openbsd.org/softraid.4">softraid(4)</a>, plug potential leak of device list.
<li>In switchd(8), parse and print OpenFlow 1.3 PACKET_IN and OXM (Openflow eXtended Match).
<li>In <a href="https://man.openbsd.org/netstat.1">netstat(1)</a>, print the relevant counters to tune the TCP SYN cache.
<li>In <a href="https://man.openbsd.org/iwm.4">iwm(4)</a>, disable the beacon filter. This make it possible to keep track of HT protection changes.
<li>In net80211, enable RTS for frames above a particular size. This change allows for reasonable throughput on loaded 11g networks whereas before they were practically unusable.
<li>In switchd(8), update OpenFlow 1.3 stub based on the 1.0 code.
<li>In switchd(8), add the -n flag to check the configuration and exit.
<li>In <a href="https://man.openbsd.org/iwm.4">iwm(4)</a>, properly keep track of HT protection changes while associated.
<li>Unbreak <a href="https://man.openbsd.org/ural.4">ural(4)</a>, which had been dropping frames on Tx while the IFF_RUNNING flag was set.
<li>In <a href="https://man.openbsd.org/ehci.4">ehci(4)</a>, use for ATI controllers the same workaround as for VIA controllers. This should hopefully help people reporting errors with SB700.
<li>Add the tcp.synhashsize <a href="https://man.openbsd.org/sysctl.8">sysctl(8)</a> to make the size for the syn cache hash array tunable.
<!-- 2016-07-19 -->
<li>In <a href="https://man.openbsd.org/dhclient.8">dhclient(8)</a>, narrow the BPF read filter rules so only packets sent to the interface's LLADDR pass. This limits the number of packets that get dropped as a result of dhclient setting BIOCSFILDROP on the bpf descriptor.
<li>Import switch(4), switchd(8) and switchctl(8), a basic work-in-progress OpenFlow implementation (not build by default).
<li>In <a href="https://man.openbsd.org/carp.4">carp(4)</a>, fix the check supposed to prevent "ip" and "ip-stealth" balancing modes from leaking the multicast address.
<li>In <a href="https://man.openbsd.org/sshd_config.5">sshd_config(5)</a>, allow wildcard for PermitOpen hosts as well as ports (bz#2582).
<li>In "<a href="https://man.openbsd.org/rcctl.8">rcctl</a> ls", skip all files with a "." in the name, because <a href="https://man.openbsd.org/pkg_add.1">pkg_add(1)</a> renames files in this way when the checksums don't match.
<li>In <a href="https://man.openbsd.org/netstart.8">netstart(8)</a>, unbreak <a href="https://man.openbsd.org/vlan.4">vlan(4)</a> on top of <a href="https://man.openbsd.org/tap.4">tap(4)</a>.
<!-- 2016-07-18 -->
<li>In virtio, always allow MSI/MSI-X. This enables MSI-X with qemu's old "82441FX" pci-bridge.
<li>In <a href="https://man.openbsd.org/armv7/sxitimer.4">sxitimer(4/armv7)</a>, explicitly stop the timers before reloading them. This fixes a hang on the Olimex A10s boards.
<li>In <a href="https://man.openbsd.org/doas.1">doas(1)</a>, copy the path to the shell from struct passwd to prevent it from being overridden by a <a href="https://man.openbsd.org/getpwuid.3">getpwuid(3)</a> call. This happens in a double doas call.
<li>In <a href="https://man.openbsd.org/iwm.4">iwm(4)</a>:
<ul>
<li>Retry Tx of management frames less often.
<li>Fix inverted logic in iwm_tx().
<li>Explicitly set firmware Tx aggregation limit to one (which disables Tx aggregation).
</ul>
<li>In <a href="https://man.openbsd.org/pstat.8">pstat(8)</a>, fix VFLAG formatting.
<li>In <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>, reduce timing attack against obsolete CBC modes by always computing the MAC over a fixed size of data.
<li>In <a href="https://man.openbsd.org/kdump.1">kdump(1)</a>, <a href="https://man.openbsd.org/ktrace.1">ktrace(1)</a> and <a href="https://man.openbsd.org/ltrace.1">ltrace(1)</a>, add "p" trace point for KTRFAC_PLEDGE, and fix handling of -t+ in <a href="https://man.openbsd.org/ltrace.1">ltrace(1)</a>.
<!-- 2016-07-17 -->
<li>Attach <a href="https://man.openbsd.org/armv7/sunxi.4">sunxi(4/armv7)</a> based on the compatible property of the root node of the device tree.
<!-- 2016-07-16 -->
<li>In <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>, support UTF-8 characters in ssh banners (bz#2058).
<li>In <a href="https://man.openbsd.org/jot.1">jot(1)</a>, fix a bug causing values to be printed out of bounds if the precision is 0.
<li>In <a href="https://man.openbsd.org/ldpd.8">ldpd(8)</a>:
<ul>
<li>Fix parsing of malformed optional TLVs/Sub-TLVs.
<li>Remove potential overflow when validating message's length.
</ul>
<li>In <a href="https://man.openbsd.org/virtio.4">virtio(4)</a>, support MSI-X. This increases performance for interrupt heavy loads.
<!-- 2016-07-15 -->
<li>In libssl, limit the support of the "backward compatible" ssl2 handshake to only be used if TLS 1.0 is enabled.
<li>In <a href="https://man.openbsd.org/ldpd.8">ldpd(8)</a>:
<ul>
<li>Update per-neighbor GTSM options on config reload.
<li>Explicitly ignore the Hop Count and Path Vector TLVs.
<li>Improve logging of reserved labels.
</ul>
<li>Disable acpicbkbd(4) by default until after the release. It causes the kernel to spin forever on certain Chromebooks.
<!-- 2016-07-14 -->
<li>In <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>, reduce the syslog level of some relatively common protocol events from LOG_CRIT (bz#2585).
<li>Add a ProxyJump <a href="https://man.openbsd.org/ssh_config.5">ssh_config(5)</a> option and a corresponding -J <a href="https://man.openbsd.org/ssh.1">ssh(1)</a> command-line flag to allow simplified indirection through a SSH bastion or "jump host".
<li><strong>5.8 and 5.9 RELIABILITY FIX: Splicing sockets in a loop could cause a kernel spin.</strong><br>A source code patch is available for <a href="errata58.html#018_splice">5.8</a> and <a href="errata59.html#013_splice">5.9</a>.
<li><strong>5.8 and 5.9 RELIABILITY FIX: ufs_readdir failed to limit size of memory allocation, leading to panics. </strong><br>A source code patch is available for <a href="errata58.html#019_dirent">5.8</a> and <a href="errata59.html#015_dirent">5.9</a>.
<li><strong>5.8 and 5.9 SECURITY FIX: The mmap extension __MAP_NOFAULT could overcommit resources and crash the system.</strong><br>A source code patch is available for <a href="errata58.html#020_mmap">5.8</a> and <a href="errata59.html#016_mmap">5.9</a>.
<li><strong>5.8 and 5.9 RELIABILITY FIX: Tick counting overflows could cause a kernel crash.</strong><br>A source code patch is available for <a href="errata58.html#021_timeout">5.8</a> and <a href="errata59.html#018_timeout">5.9</a>.
<li><strong>5.8 and 5.9 RELIABILITY FIX: Invalid file descriptor use with kevent(2) could lead to a kernel crash.</strong><br>A source code patch is available for <a href="errata58.html#022_kevent">5.8</a> and <a href="errata59.html#019_kevent">5.9</a>.
<li><strong>5.8 and 5.9 RELIABILITY FIX: Unchecked parameters and integer overflows in the amap allocation routines could cause malloc(9) to either not allocate enough memory, leading to memory corruption, or to trigger a "malloc: allocation too large" panic.</strong><br>A source code patch is available for <a href="errata58.html#023_amap">5.8</a> and <a href="errata59.html#020_amap">5.9</a>.
<li><strong>5.9 RELIABILITY FIX: Multiple processes exiting with a fd-passing control message on a shared socket could crash the system.</strong><br>A source code patch is available for <a href="errata59.html#014_unp">5.9</a>.
<li><strong>5.9 RELIABILITY FIX: A race occuring in the unlocked ARP input path can lead to a kernel NULL dereference.</strong><br>A source code patch is available for <a href="errata59.html#017_arp">5.9</a>.
<li>Ensure that amap slot calculation does not overflow. This prevents from too small amaps being allocated by forcing the allocation of a large number of slots.
<li>Ignore the kern.usermount <a href="https://man.openbsd.org/sysctl.8">sysctl(8)</a>. It is unsafe, because it allows any non-<a href="https://man.openbsd.org/pledge.2">pledge(2)</a>'d program to call the mount/umount system calls. The sysctl will be completely removed in 6.1.
<li>In <a href="https://man.openbsd.org/ip6.4">ip6(4)</a>, drop received packets with an IPv4-compatible address as source or destination as per RFC4213.
<li>In <a href="https://man.openbsd.org/armv7/fec.4">fec(4/armv7)</a>, do board-specific delay/skew corrections for the Micrel KSZ9021 and KSZ9031 PHYs based on device tree properties instead of the board ID.
<li>Prevent a use-after-free by not updating an ARP entry that has been removed from the table.
<li>In <a href="https://man.openbsd.org/vioblk.4">vioblk(4)</a>, properly handle poll timeout.
<!-- 2016-07-13 -->
<li>Avoid a panic caused by very big mallocs for the ufs_readdir() buffer which should have been limited to 64 kB.
<li>Avoid a panic caused by very big mallocs that result from uint64-to-int32 truncation when kevent does fd validation.
<li>On amd64, add hvn(4), a work-in-progress driver for the Hyper-V NetVSC.
<li>In <a href="https://man.openbsd.org/calendar.1">calendar(1)</a>, when matching a day in the month, ensure the date is still in the month we are interested in. This
fixes things like Sunday+5 for months where there is not a 5th Sunday.
<li>In <a href="https://man.openbsd.org/bpgd.8">bpgd(8)</a>, output the no-longer-so-new AS operators when printing the configuration.
<li>In libtls, split the existing TLS cipher suite groups into four: secure, compat, legacy and insecure.
<li>Check resource limits for mappings established using __MAP_NOFAULT. This prevents callers from triggering a kernel panic and a potential integer overflow in the amap code by forcing the allocation of too many slots.
<li>In imxehci(4), use the device tree voltage regulator information to supply power to the USB bus, because this only supports "fixed" regulators that are controlled through a gpio.
<!-- 2016-07-12 -->
<li>Fix a crash when MNT_DOOMED is passed in the flags to <a href="https://man.openbsd.org/unmount.2">unmount(2)</a>.
<li>In <a href="https://man.openbsd.org/syslogd.8">syslogd(8)</a>, add support for TLS client certificates in syslogd. This allows the remote server to verify the authenticity of received messages.
<!-- 2016-07-11 -->
<li>In tmpfs, don't allow mounting with noval owner. It causes a panic later on.
<li>In <a href="https://man.openbsd.org/factor.6">factor(6)</a>, use an integer version of the Newton method instead of the floating point square root. This fixes a rounding issue.
<li>In <a href="https://man.openbsd.org/armv7/imxesdhc.4">imxesdhc(4/armv7)</a> and <a href="https://man.openbsd.org/armv7/fec.4">fec(4/armv7)</a>, use the gpio framework to implement card detect instead of hardcoding particular gpios based on board IDs.
<li>Hook up imxgpio(4) to the FDT gpio framework.
<li>Fix path MTU discovery which was slightly broken: it took two ICMP packets to create and change the dynamic route.
<li>In <a href="https://man.openbsd.org/tcp.4">tcp(4)</a>, do not increase the size of the socket buffer under memory pressure.
<!-- 2016-07-10 -->
<li>In <a href="https://man.openbsd.org/tpcump.8">tcpdump(8)</a>, recognize MPLS pseudowire with control words. Also print encapsulated ethernet packets.
<li>In <a href="https://man.openbsd.org/acpimadt.4">acpimadt(4)</a>, properly handle Processor Local X2APIC structures. This makes secondary CPUs attach on the HP DL360 gen 9.
<li>Dynamically attach imxgpio(4) using the FDT.
<li>In <a href="https://man.openbsd.org/mandoc.1">mandoc(1)</a>, fix a bug causing .so links to gzipped manuals to fail in the absence of a <a href="https://man.openbsd.org/mandoc.db.5">mandoc.db(5)</a> database.
<!-- 2016-07-09 -->
<li>In <a href="https://man.openbsd.org/armv7/omap.4">omap(4/armv7)</a>, follow imx and match based on the compatible property of the root node in the fdt instead of attaching the device based on board IDs.
<li>Dynamically attach i.MX6 <a href="https://man.openbsd.org/ehci.4">ehci(4)</a> using the FDT.
<!-- 2016-07-07 -->
<li>In <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>, improve crypto ordering for Encrypt-then-MAC (EtM) mode MAC algorithms. This prevents the possibility of a side-channel oracle, though no such oracle has been identified.
<li>In <a href="https://man.openbsd.org/perl.1">perl(1)</a>, fix a bug where XSLoader could try to load from a subdir of the cwd when called via eval (CVE-2016-6185).
<!-- 2016-07-06 -->
<li>In <a href="https://man.openbsd.org/malloc.3">malloc(3)</a>, correctly implement the three-valued J/j option.
<li>In <a href="https://man.openbsd.org/syslogd.conf.5">syslogd.conf(5)</a>, allow space-deliminated fields in syslog.conf in addition to traditional tabs-deliminated fields.
<li>Various cleanups in <a href="https://man.openbsd.org/route6d.8">route6d(8)</a>.
<li>Fix several places where calculating ticks could overflow, because on arithmetic overflows the compiler may decide to do anything.
<!-- 2016-07-05 -->
<li>In libtls, correctly handle an EOF that occurs prior to the TLS handshake completing.
<li>Update to tzdata2016f.
<li>Build <a href="https://man.openbsd.org/eeprom.8">eeprom(8)</a> on octeon.
<li>On octeon, add <a href="https://man.openbsd.org/openprom.4">openprom(4)</a>.
<!-- 2016-07-04 -->
<li>In libcrypto, add several fixes to make OCSP work with intermediate certificates provided in the response.
<li>In <a href="https://man.openbsd.org/ld.so.1">ld.so(1)</a>, remove unfinished prebind support.
<li>Avoid an integer overflow of the thrsleep() timeout. This prevents a panic.
<li>On the Quad-G5, make <a href="https://man.openbsd.org/macppc/hpb.4">hpb(4)</a> attach first when iterating PCI buses to allow <a href="https://man.openbsd.org/macppc/openpic.4">openpic(4)</a> to properly map interrupt for the devices instead of possibly dereferencing garbage.
