<h3>What's New</h3>
<p>
This is a partial list of new features and systems included in OpenBSD 7.3.
For a comprehensive list, see the <a href="plus73.html">changelog</a> leading
to 7.3.
<ul>
<li>Various kernel improvements:
<ul>
<li>Added <a href="https://man.openbsd.org/waitid.2">waitid(2)</a>,
wait for process state change.
<li>Added <a href="https://man.openbsd.org/pinsyscall.2">pinsyscall(2)</a>,
specify the call stub for a specific system call.
<li>Added <a href="https://man.openbsd.org/getthrname.2">getthrname(2)</a> and
<a href="https://man.openbsd.org/setthrname.2">setthrname(2)</a>,
get or set thread name.
<li>Added WTRAPPED option for <a
href="https://man.openbsd.org/waitid.2">waitid(2)</a> to control
whether CLD_TRAPPED state changes, i.e., ptrace(2) on a process, are reported.
<!-- kernel internals -->
<li>Introduced <a
href="https://man.openbsd.org/clockintr.9">clockintr(9)</a>, a
machine-independent clock interrupt scheduler. Switched all
architectures to use the new subsystem.
<li>Introduced a new kern.autoconf_serial <a
href="https://man.openbsd.org/sysctl.8">sysctl(8)</a> that can be used
by userland to monitor state changes of the kernel device tree.
<li>Fixed <a href="https://man.openbsd.org/pmap.9">pmap(9)</a> bugs
involving entering an executable mapping for a page before
synchronizing the data and instruction cache on arm64 and riscv64.
<li>Removed copystr(9) from the public API.
<li>Added <a
href="https://man.openbsd.org/getnsecruntime.9">getnsecruntime(9)</a>.
Offers fast access to the system runtime clock at the cost of precision.
<li>Prevent detaching ("bioctl -d detach") of a boot volume on a RAID managed by <a
href="https://man.openbsd.org/bioctl.8">bioctl(8)</a>.
<li>On arm64, avoid using 1GB mappings for the identity map in the
early kernel bootstrap phase and when booting the secondary CPUs. This
avoids accidentally mapping memory regions that should not be mapped
(i.e. secure memory) as all mapped memory can be accessed
speculatively.
<li>On arm64, add a machdep.lidaction <a
href="https://man.openbsd.org/sysctl.8">sysctl(8)</a> for <a
href="https://man.openbsd.org/aplsmc.4">aplsmc(4)</a> Apple Silicon
laptops.<br>
The arm64 default for the machdep.lidaction is 1, making the
system suspend when the lid is closed. <a
href="https://man.openbsd.org/aplsmc.4">aplsmc(4)</a> provides support
for the lid position sensor.
<li>Changed arm64 suspend idle loop from WFE to WFI, avoiding spurious
wakeups while other CPUs are still active.
<li>Added new <a href="https://man.openbsd.org/dt.4">dt(4)</a> tracing ioctl
DTIOCGARGS to get the types of probe arguments.
</ul>
<li>SMP Improvements
<ul>
<li>Unlocked <a href="https://man.openbsd.org/mmap.2">mmap(2)</a>, <a
href="https://man.openbsd.org/munmap.2">munmap(2)</a>, and <a
href="https://man.openbsd.org/mprotect.2">mprotect(2)</a>.
<li>Unlocked <a href="https://man.openbsd.org/sched_yield.2">sched_yield(2)</a>.
<li>Added support for per-CPU counters to
<a href="https://man.openbsd.org/evcount.9">evcount(9)</a>.
Useful for counting events that are prone to occur simultaneously
across multiple CPUs, like clock interrupts and IPIs.
<li>Moved <a href="https://man.openbsd.org/pf.4">pf(4)</a> purge
tasks out from under the kernel lock.
<li>Unlocked <a href="https://man.openbsd.org/ioctl.2">ioctl(2)</a>
SIOCGIFCONF, SIOCGIFGMEMB, SIOCGIFGATTR, and SIOCGIFGLIST.
<li>Protected interface tables in <a
href="https://man.openbsd.org/pf.4">pf(4)</a> with PF_LOCK(), allowing
removal of NET_LOCK() protection from the <a
href="https://man.openbsd.org/ioctl.2">ioctl(2)</a> code path in pf.
<li>Unlocked <a
href="https://man.openbsd.org/getsockopt.2">getsockopt(2)</a> and <a
href="https://man.openbsd.org/setsockopt.2">setsockopt(2)</a>.
<li>Completed removing kernel lock from IPv6 read ioctls.
<li>Unlocked <a href="https://man.openbsd.org/minherit.2">minherit(2)</a>.
<li>Made <a href="https://man.openbsd.org/tun.4">tun(4)</a> and <a
href="https://man.openbsd.org/tap.4">tap(4)</a> event filters MP-safe.
<li>Unlocked <a href="https://man.openbsd.org/utrace.2">utrace(2)</a>.
<li>Stopped holding the vm_map lock while flushing pages in <a
href="https://man.openbsd.org/msync.2">msync(2)</a> and <a
href="https://man.openbsd.org/madvise.2">madvise(2)</a>. Prevents a
3-thread deadlock between <a
href="https://man.openbsd.org/msync.2">msync(2)</a>, page-fault and <a
href="https://man.openbsd.org/mmap.2">mmap(2)</a>.
<li>Unlocked <a
href="https://man.openbsd.org/select.2">select(2)</a>, <a
href="https://man.openbsd.org/pselect.2">pselect(2)</a>, <a
href="https://man.openbsd.org/poll.2">poll(2)</a>, and <a
href="https://man.openbsd.org/ppoll.2">ppoll(2)</a>.
</ul>
<li>Direct Rendering Manager and graphics drivers
<ul>
<li>Updated <a href="https://man.openbsd.org/drm.4">drm(4)</a>
to Linux 6.1.15
<li><a href="https://man.openbsd.org/drm.4">amdgpu(4)</a>: Added
support for Ryzen 7000 "Raphael", Ryzen 7020 series "Mendocino",
Ryzen 7045 series "Dragon Range",
Radeon RX 7900 XT/XTX "Navi 31",
Radeon RX 7600M (XT), 7700S, and 7600S "Navi 33."
<li>Fixed frame buffer corruption and additional bugs after wakeup
on Apple Silicon laptops and the Lenovo x13s.
<li>Added support for the backlight connector property to <a
href="https://man.openbsd.org/amdgpu.4">amdgpu(4)</a> as in <a
href="https://man.openbsd.org/inteldrm.4">inteldrm(4)</a>, making <a
href="https://man.openbsd.org/xbacklight.1">xbacklight(1)</a> work
when using the Xorg modesetting driver.
</ul>
<li>VMM/VMD improvements
<ul>
<li>Updated <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> to
permit SVM guests read access to MSR_HWCR and MSR_PSTATEDEF.
Guests can use these registers on AMD 17h and 19h hosts to
determine the TSC frequency without calibrating against a
second clock.
<li>Allocated reference for vm and vcpu SLISTs in <a
href="https://man.openbsd.org/vmm.4">vmm(4)</a>, keeping vmm from
triggering excessive wakeup calls while iterating through the list of
vms while servicing an <a
href="https://man.openbsd.org/ioctl.2">ioctl(2)</a>.
<li>Set <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> RAX guest
register state based on VMCB.
<li>Removed locking in <a
href="https://man.openbsd.org/vmm.4">vmm(4)</a> vmm_intr_pending,
reducing slowdowns due to requests for a lock held while the VM is
running.
<li>Increased speed of delivery of interrupts to a running vcpu in <a
href="https://man.openbsd.org/vmm.4">vmm(4)</a>.
<li>Made <a href="https://man.openbsd.org/vmm.4">vmm(4)</a> treat vcpu
lists as immutable, removing the need to reference count individual
vcpu objects and use a rwlock.
<li>Implemented zero-copy operations on virtqueues in <a
href="https://man.openbsd.org/vmd.8">vmd(8)</a>.
<li>Provided a detailed e820 memory map when booting <a
href="https://man.openbsd.org/vmd.8">vmd(8)</a> guests with SeaBIOS.
When a vm initializes memory ranges, we now track what each range
represents. This information can be used to supply the e820 memory map
to SeaBIOS via the fw_cfg interface allowing it to properly
communicate memory ranges to a guest operating system. With this
special cases in ports can be removed.
<li>Added thread names to vm processes in <a
href="https://man.openbsd.org/vmd.8">vmd(8)</a>, visible in <a
href="https://man.openbsd.org/ps.1">ps(1)</a>.
<li>Hid the WAITPKG cpu feature from <a
href="https://man.openbsd.org/vmm.4">vmm(4)</a> guests, preventing
invalid instruction exceptions. Also added WAITPKG feature
identification to i386 and amd64.
<li>Changed <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> to
only open /dev/vmm once, having the parent process send the fd to the
vmm child process.
<li>Restricted <a href="https://man.openbsd.org/vmm.4">vmm(4)</a>
exposed cpuid extended feature flags.
<li>Adjusted <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> error
paths to avoid removal of configuration-defined (known) VMs on error.
<li>Stopped being paranoid about hypervisor correct PKU handling.<br>
Added saving and restoring guest PKRU to <a
href="https://man.openbsd.org/vmm.4">vmm(4)</a>. Expose the PKU cpuid
bit to the guest if in use on the host.
<li>Made <a href="https://man.openbsd.org/vmd.8">vmd(8)</a> scan the
PCI bus to determine bootorder strings.
</ul>
<li>Various new userland features:
<ul>
<li>Added <a href="https://man.openbsd.org/kdump.1">kdump(1)</a>
argument support for msyscall, pledge, unveil, __realpath, ypconnect
and __tmpfd.
<li>Added <a
href="https://man.openbsd.org/mimmutable.2">mimmutable(2)</a> and <a
href="https://man.openbsd.org/munmap.2">munmap(2)</a> reporting to <a
href="https://man.openbsd.org/kdump.1">kdump(1)</a>.
<li>Added <a
href="https://man.openbsd.org/lastcomm.1">lastcomm(1)</a> reporting
for process kills due to <a
href="https://man.openbsd.org/execve.2">execve(2)</a> from non-pinned
syscall address.
</ul>
<li>Various bugfixes and tweaks in userland:
<ul>
<li>Allow TZ to contain absolute paths starting with /usr/share/zoneinfo.
All absolute paths were ignored in 7.2 to avoid
<a href="https://man.openbsd.org/unveil.2">unveil(2)</a> violations.
<li>Made <a href="https://man.openbsd.org/ldomctl.8">ldomctl(8)</a>
accept more descriptive name-based paths in addition to number-based
paths in <a
href="https://man.openbsd.org/ldom.conf.5">ldom.conf(5)</a>.
<li>Dropped support for $rc_exec in <a
href="https://man.openbsd.org/rc.subr.8">rc.subr(8)</a>. The rc_exec
function should be used instead.
<li>Excluded /tmp/*.shm files from /tmp cleaning in <a
href="https://man.openbsd.org/daily.8">daily(8)</a>. Removing them
interferes with programs that use shared memory via <a
href="https://man.openbsd.org/shm_open.3">shm_open(3)</a>.
<li>Added zap-to-char and zap-up-to-char to <a
href="https://man.openbsd.org/mg.1">mg(1)</a>. Bound zap-to-char to
M-z.
<li>Fixed handling of escaped backslashes in <a
href="https://man.openbsd.org/vi.1">vi(1)</a> ex_range.
<li>Added support to <a
href="https://man.openbsd.org/gunzip.1">gunzip(1)</a> for zip files
that contain a single member.

bytes read/written and the ? prompt to stdout, not stderr.
<li>Changed the vmstat view in <a
href="https://man.openbsd.org/systat.1">systat(1)</a> to measure
elapsed time with <a
href="https://man.openbsd.org/clock_gettime.2">clock_gettime(2)</a>
instead of statclock ticks.
<li>Improved the periodic display in <a
href="https://man.openbsd.org/iostat.8">iostat(8)</a>.
<li>Fixed an edge case in <a href="https://man.openbsd.org/top.1">top(1)</a>
where summary statistics for offline CPUs were displayed.
<li>Added support for a personal <a
href="https://man.openbsd.org/units.1">units(1)</a> library by passing
-f multiple times.
<li>Changed <a href="https://man.openbsd.org/df.1">df(1)</a> to
round up fractional percentages.
<li>Fixed unbounded variable expansion in <a
href="https://man.openbsd.org/pkg-config.1">pkg-config(1)</a>.
<li>Switched to use <a
href="https://man.openbsd.org/llvm-strip.1">llvm-strip(1)</a> on
architectures that use <a
href="https://man.openbsd.org/ld.lld.1">ld.lld(1)</a>.
<!-- rc scripts -->
<li>Made <a href="https://man.openbsd.org/rc.8">rc(8)</a> reorder
libraries in parallel to <a
href="https://man.openbsd.org/netstart.8">netstart(8)</a>, as this
does not depend on network access.
<li>Made <a href="https://man.openbsd.org/rc.8">rc(8)</a> print the
name of each library before relinking as a signal to the operator that
boot has not stalled.
<!-- audio -->
<li>Added a -w flag to <a
href="https://man.openbsd.org/audioctl.8">audioctl(8)</a> for
displaying variables periodically.
<li>Added short options for <a
href="https://man.openbsd.org/timeout.1">timeout(1)</a> --foreground
and --preserve-status.
<li>Added signal as a full argument name for <a
href="https://man.openbsd.org/timeout.1">timeout(1)</a> -s.
<li>Fixed .wav files generated by <a
href="https://man.openbsd.org/aucat.1">aucat(1)</a> by using extended
header format.
<!-- disks ... -->
<li>In <a
href="https://man.openbsd.org/disklabel.8">disklabel(8)</a>, use the
size of the largest chunk of free space, not the total of all such
chunks, when checking for sufficient space to add a partition.
<li>Extended <a
href="https://man.openbsd.org/disklabel.8">disklabel(8)</a> template
parsing to allow "[mount point] *" as the specification for putting
the maximum available free space into a partition. Extended
command line parsing to allow "T-" as the specification to read the
template from stdin.
<li>Repaired <a
href="https://man.openbsd.org/disklabel.8">disklabel(8)</a>
to check for D_VENDOR flag in d_flags, not d_secpercyl.
<li>Removed remnants of DEC standard 144 bad sector code from
<a

<li>Fixed <a href="https://man.openbsd.org/iwx.4">iwx(4)</a> session
protection event duration.
</ul>
<li>IEEE 802.11 wireless stack improvements and bugfixes:
<ul>
<li>Made net80211 drop beacons received on secondary HT/VHT
channels, preventing <a
href="https://man.openbsd.org/iwm.4">iwm(4)</a> firmware panics and
making association work with 11ac APs which transmit beacons on
channels other than their primary.
<li>Made WEP encryption work on <a
href="https://man.openbsd.org/bwfm.4">bwfm(4)</a>.
</ul>
<li>Installer, upgrade and bootloader improvements:
<ul>
<li>Made installer answers <code>!</code> and <code>(S)hell</code> drop into a <a
href="https://man.openbsd.org/ksh.1">ksh(1)</a> environment rather
than the more limited <a href="https://man.openbsd.org/sh.1">sh(1)</a>.
<li>Added support for configuring interfaces by lladdr (MAC).
<li>Made the installer skip interface configuration questions when no interfaces are available.
<li>Fixed resizing partitions on an auto-allocated disk that had a boot partition.
<li>Stopped the installer from asking to initialize disks that have
<a href="https://man.openbsd.org/softraid.4">softraid(4)</a> chunks.
<li>Made efiboot fdt support device trees with NOPs in them (like the kernel version).
<li>Improved the default choice for the installer's install media
disk question to show the first disk that (a) is not the root disk and (b)
is not a disk with softraid chunks (hosting the root disk, for example).
<li>Stopped offering WEP in the installer if not supported.
<li>Fixed lock file error on installer exit/abort.
<li>Made <a href="https://man.openbsd.org/installboot.8">installboot(8)</a> <code>-p</code>
support <a href="https://man.openbsd.org/softraid.4">softraid(4)</a>.
<li>Made <a href="https://man.openbsd.org/installboot.8">installboot(8)</a> silently skip
<a href="https://man.openbsd.org/softraid.4">softraid(4)</a> keydisks.
<li>Fixed passing explicit stages files to
<a href="https://man.openbsd.org/installboot.8">installboot(8)</a>.
<!-- architecture specific -->
<li>Added <a
href="https://man.openbsd.org/mount_nfs.8">mount_nfs(8)</a> to the
sparc64 installer, to fetch sets over NFS.
<li>Copy the apple-boot firmware to EFI system partition, enabling
automatic bootloader updates on Apple Silicon computers.
<li>Made the installer stop printing MD post installation instructions on upgrades.
<li>Made it possible to set keyboard layout(s) in arm64's installer.
<li>Added initial support in the installer for guided disk

<li>Added passing of boot device information from the bootloader to
the kernel on luna88k.
<li>Switched luna88k boot loader to MI boot code.
<li>Made the luna88k bootloader display a puffy boot logo.
<li>Made <a href="https://man.openbsd.org/ls.1">ls(1)</a> work
correctly in the luna88k bootloader.
<li>Made <a href="https://man.openbsd.org/time.1">time(1)</a> work
correctly in the luna88k bootloader.
<li>Removed dangerous user-settable "addr" variable from MI

<a href="https://man.openbsd.org/installboot.8">installboot(8)</a> <code>-p</code>.
<li>Fixed ofwboot OpenFirmware <code>map</code> call to unbreak boot on some machines.
<li>Reduced ofwboot.net size after libz update to unbreak netboot on some machines.
<li>Made riscv64 bootloader support boot from RAID 1C softraid volumes.
<li>Made <a href="https://man.openbsd.org/installboot.8">installboot(8)</a> support
<a href="https://man.openbsd.org/softraid.4">softraid(4)</a> on riscv64.
<li>Stopped creating defunct vax (ra, rx), hp300 (hd) and sparc (xy, xd)
devices in /dev.
</ul>
<li>Security improvements:
<ul>
<li>Permissions (RWX, MAP_STACK, etc.) on address space regions can
be made <a href="https://man.openbsd.org/mimmutable.2">immutable</a>,
so that <a href="https://man.openbsd.org/mmap.2">mmap(2)</a>, <a
href="https://man.openbsd.org/mprotect.2">mprotect(2)</a> or <a
href="https://man.openbsd.org/munmap.2">munmap(2)</a> fail with EPERM.
Most of the program static address space is now automatically
immutable (main program, ld.so, main stack, load-time shared
libraries, and dlopen()'d libraries mapped without RTLD_NODELETE).
Programmers can request non-immutable static data using the
"openbsd.mutable" section, or manually bring immutability to (page
aligned heap objects) using <a
href="https://man.openbsd.org/mimmutable.2">mimmutable(2)</a>.
The main internal data of <a
href="https://man.openbsd.org/malloc.3">malloc(3)</a>
is marked immutable.
<li>Some architectures now have non-readable code ("xonly"), both from
the perspective of userland reading its own memory, or the kernel
trying to read memory in a system call. Many sloppy practices in
userland code had to be repaired to allow this. The linker
(<a href="https://man.openbsd.org/ld.lld.1">ld.lld(1)</a> or
<a href="https://man.openbsd.org/ld.bfd.1">ld.bfd(1)</a>) option
--execute-only is enabled by default. In order of development: arm64,
riscv64, hppa, amd64, powerpc64, powerpc (G5 only), octeon, and sparc64
(sun4u only; unfinished).
<li>These can still benefit from switching to --execute-only binaries if the
cpu generates different traps for instruction-fetch versus data-fetch.
The VM system will not allow memory to be read before it was executed
which is valuable together with library relinking. Architectures
switched over include loongson.
<li><a href="https://man.openbsd.org/ld.so.1">ld.so(1)</a> and crt0
register the location of the <a
href="https://man.openbsd.org/execve.2">execve(2)</a> stub with the
kernel using pinsyscall(2), after which the kernel only accepts an
execve call from that specific location.
<li>Added <a href="https://man.openbsd.org/execve.2">execve(2)</a>
violations of <a
href="https://man.openbsd.org/pinsyscall.2">pinsyscall(2)</a> policy
to the daily mail, available by setting rc.conf.local(5)
accounting=YES.
<li>Added retguard (consistency-check the return address on the
stack) to amd64 syscalls.
<li>sshd random relinking at boot: Randomly relink and install <a
href="https://man.openbsd.org/sshd.8">sshd(8)</a>, resulting
in a sshd binary with unknown address layout after every reboot.
<li>Add another mitigation against classic BROP on systems without
execute-only mmu hardware-enforcement. A range-checking wrapper in
front of <a href="https://man.openbsd.org/copyin.9">copyin(9)</a> and
<a href="https://man.openbsd.org/copyinstr.9">copyinstr(9)</a> ensures
the userland source address doesn't overlap the main program text and
other text segments, thereby making these address ranges unreadable to
the kernel. No programs have been discovered which require reading
their own text segments with a system call.
<li>On arm64, introduce mitigation of the Spectre-BHB (Branch
History Injection) CPU vulnerability by using core-specific trampoline
vectors.
<li>Enabled the arm64 Data Independent Timing (DIT) feature in both the kernel and
userland on CPUs that support it to mitigate timing side-channel
attacks.
</ul>
<li>Changes in the network stack:
<ul>
<li>Made /dev/pf a clonable device to better track kernel resources
used by processes.
<li>Modified TCP receive buffer size auto-scaling to use the smoothed
RTT (SRTT) instead of the timestamp option, which improves performance
on high latency networks if the timestamp option isn't available.
<li>Relaxed the requirement for multicast support of interfaces for
configuring IPv6. This allows non-multicast interfaces such as
point-to-point interfaces and the NBMA / point-to-multipoint
interfaces like mpe(4), mgre(4) and wg(4) to work with IPv6.
<li>Measure the TCP_KEEPALIVE timeout with <a
href="https://man.openbsd.org/getnsecruntime.9">getnsecruntime(9)</a>
instead of the system uptime.
Prevents TCP connections from needlessly failing en masse after
waking a system from suspend.
<li>Used stoeplitz (symmetric Toeplitz hash algorithm) to generate a
hash/flowid for <a href="https://man.openbsd.org/pf.4">pf(4)</a> state
keys. With this change, pf will hash traffic the same way that
hardware using a stoeplitz key will hash incoming traffic on rings.
stoeplitz is also used by the TCP stack to generate a flow id, which
is used to pick which transmit ring is used on nics with multiple
queues, too. Using the same algorithm throughout the stack encourages
affinity of packets to rings and softnet threads the whole way
through.
<li>Prevented possible kernel crashes by dropping TCP packets with
destination port 0 in <a href="https://man.openbsd.org/pf.4">pf(4)</a>
and the stack.
<li>Fixed an endian swap bug causing problems with <a
href="https://man.openbsd.org/vlan.4">vlan(4)</a> on <a
href="https://man.openbsd.org/em.4">em(4)</a> sparc64 systems.
<li>Denied "pipex no" tunnel setting for <a
href="https://man.openbsd.org/pppx.4">pppx(4)</a> interfaces.
<li>Fixed <a href="https://man.openbsd.org/pfsync.4">pfsync(4)</a>
crashing on pf_state_key removal.
<li>Fixed a panic in <a
href="https://man.openbsd.org/pfsync.4">pfsync(4)</a> when there is
no data ready for bulk transfer.
<li>Turned off TCP Segmentation Offload (TSO) if interface is added
to layer 2 devices.
<li>Improved <a href="https://man.openbsd.org/vnet.4">vnet(4)</a>
to work better in busy conditions.
<li>Added a <a href="https://man.openbsd.org/bpf.4">bpf(4)</a> timeout
(BIOCSWTIMEOUT) between capturing a packet and making the buffer
readable, preventing, for example, <a
href="https://man.openbsd.org/pflogd.8">pflogd(8)</a> waking every
half second even if there is nothing to read. By default this buffer
is infinite and must be filled to become readable.
<li>Avoided enabling TSO on interfaces which are already attached to a bridge.
</ul>
<li>Routing daemons and other userland network improvements:
<ul>
<li>IPsec support was improved:
<ul>
<li>Added <a href="https://man.openbsd.org/iked.8">iked(8)</a>
support for configuring multiple name servers.
<li>Synced proc.c from <a
href="https://man.openbsd.org/vmd.8">vmd(8)</a> to <a
href="https://man.openbsd.org/iked.8">iked(8)</a> to enable fork +
exec for all processes. This gives each process a fresh and unique
address space to further improve randomization of ASLR and stack
protector.
</ul>
<li>In <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>, <a
href="https://man.openbsd.org/bgpctl.8">bgpctl(8)</a> and <a
href="https://man.openbsd.org/bgplgd.8">bgplgd(8)</a>:
<ul>
<li>Improved performance by optimising the output filters.
<li>Add Autonomous System Provider Authorization (ASPA) validation
based on draft-ietf-sidrops-aspa-verification-12
<li>Introduce avs (ASPA validation state) filter and bgpctl
filter argument.
<li>Add ASPA support for the RTR protocol based on
draft-ietf-sidrops-8210bis-10.
<li>Improve open policy (RFC 9234) support and enable the capability
automatically if a role is specified for the peer.
<li>Introduce a per-neighbor 'role' configuration option to specify
the session role used by ASPA verification and the open policy
capability. The 'announce policy' statement was simplified at
the same time.
<li>Improve startup behaviour by introducing a small delay before
opening the connection to a new peer.
<li>Support for aspa-set table config which can be provided by
<a
href="https://man.openbsd.org/rpki-client.8">rpki-client(8)</a>.
<li>Make it possible to filter the RIB by invalid and leaked prefixes
in bgpctl and bgplgd.
<li>Add OpenMetrics output to bgpctl for various BGP statistics and
add /metrics endpoint to bgplgd.
<li>Fix of incorrect length checks that allowed an out-of-bounds
read in bgpd.
</ul>
<li><a href="https://man.openbsd.org/rpki-client.8">rpki-client(8)</a> saw some changes:
<ul>
<li>Add a new '-H' command line option to create a shortlist of
repositories to synchronize to. For example, when invoking
"rpki-client -H rpki.ripe.net -H chloe.sobornost.net", the utility
will not connect to any other hosts other than the two specified
through the -H option.
<li>Add support for validating Geofeed (RFC 9092) authenticators. To
see an example download https://sobornost.net/geofeed.csv and run
"rpki-client -f geofeed.csv"
<li>Add support for validating Trust Anchor Key (TAK) objects. TAK
objects can be used to produce new Trust Anchor Locators (TALs) signed
by and verified against the previous Trust Anchor. See
draft-ietf-sidrops-signed-tal for the full specification.
<li>Log lines related to RRDP/HTTPS connection problems now include the
IP address of the problematic endpoint (in brackets).
<li>Improve the error message when an invalid filename is encountered
in the rpkiManifest field in the Subject Access Information (SIA)
extension.
<li>Emit a warning when unexpected X.509 extensions are encountered.
<li>Restrict the ROA ipAddrBlocks field to only allow two
ROAIPAddressFamily structures (one per address family). See
draft-ietf-sidrops-rfc6482bis.
<li>Check the absence of the Path Length constraint in the Basic
Constraints extension.
<li>Restrict the SIA extension to only allow the signedObject and
rpkiNotify accessMethods.
<li>Check that the Signed Object access method is present in ROA, MFT,
ASPA, TAK, and GBR End-Entity certificates.
<li>In addition to the 'rsync://' scheme, also permit other schemes
(such as 'https://') in the SIA signedObject access method.
<li>Check that the KeyUsage extension is set to nothing but
digitalSignature on End-Entity certificates.
<li>Check that the KeyUsage extension is set to nothing but keyCertSign
and CRLSign on CA certificates.
<li>Check that the ExtendedKeyUsage extension is absent on CA
certificates.
<li>Fix a bug in the handling of the port of http_proxy.
<li>The '-r' command line option has been deprecated.
<li>Filemode (-f) output is now presented as a text based table.
<li>The 'expires' key in the JSON/CSV/OpenBGPD output formats is now
calculated with more accuracy. The calculation takes into account the
nextUpdate value of all intermediate CRLs in the signature path
towards the trust anchor, in addition to the expiry moment of the
leaf-CRL and CAs.
<li>Handling of CRLs and Manifests in the face of inconsistent RRDP delta
publications has been improved. A copy of an alternative version of
the applicable CRL is kept in the staging area of the cache directory,
in order to increase the potential for establishing a complete
publication point, in cases where a single publication point update
was smeared across multiple RRDP delta files.
<li>The OpenBGPD configuration output now includes validated Autonomous
System Provider Authorization (ASPA) payloads as an 'aspa-set {}'
configuration block.
<li>When rpki-client is invoked with increased verbosity ('-v'), the
current RRDP Serial and Session ID are shown to aid debugging.
<li>Self-signed X.509 certificates (such as Trust Anchor certificates)
now are considered invalid if they contain an X.509
AuthorityInfoAccess extension.
<li>Signed Objects where the CMS signing-time attribute contains a
timestamp later then the X.509 certificate's notAfter timestamp are
considered invalid.
<li>Manifests where the CMS signing-time attribute contains a timestamp
later then the Manifest eContent nextUpdate timestamp are considered
invalid.
<li>Any objects whose CRL Distribution Points extension contains a
CRLIssuer, CRL Reasons, or nameRelativeToCRLIssuer field are
considered invalid in accordance with RFC 6487 section 4.8.6.
<li>For every X.509 certificate the SHA-1 of the Subject Public Key is
calculated and compared to the Subject Key Identifier (SKI). If a
mismatch is found the certificate is not trusted.
<li>Require the outside-TBS signature OID for every X.509 intermediate
CA certificate and CRL to be sha256WithRSAEncryption.
<li>Require the RSA key pair modulus and public exponent parameters to
strictly conform to the RFC 7935 profile.
<li>Ensure there is no trailing garbage present in Signed Objects beyond
the self-embedded length field.
<li>Require RRDP Session IDs to strictly be version 4 UUIDs.
<li>When decoding and validating an individual RPKI file using filemode
(rpki-client -f file), display the signature path towards the trust
anchor and the timestamp when the signature path will expire.
<li>When decoding and validating an individual RPKI file using filemode
(rpki-client -f file), display the optional CMS signing-time,
non-optional X.509 notBefore timestamp and non-optional X.509
notAfter timestamp.
</ul>
<li>Updated zlib to 1.2.13.
<li>Fixed a long-standing bug in a libreadline header that broke the
interactive Python command line interface.
<li>Switched <a href="https://man.openbsd.org/tftpd.8">tftpd(8)</a> to
default to read-only unless -w is specified for write access (the
previous default).
<li>Stopped printing the prompt for non-interactive usage of <a
href="https://man.openbsd.org/tftp.1">tftp(1)</a>.
<li>Changed <a href="https://man.openbsd.org/rarpd.8">rarpd(8)</a> to
only unveil /tftpboot if -t is specified.
<li>Added client certificate authentication and an optional SASL
EXTERNAL bind to <a
href="https://man.openbsd.org/ypldap.8">ypldap(8)</a>.
<li>Adjusted ipv6 address width to align the display columns better
in the output of <a href="https://man.openbsd.org/ndp.8">ndp(8)</a>,
<a href="https://man.openbsd.org/route.8">route(8)</a> and <a
href="https://man.openbsd.org/netstat.1">netstat(1)</a> as already
available in <a
href="https://man.openbsd.org/systat.1">systat(1)</a>'s netstat.
<li>Used <a href="https://man.openbsd.org/stravis.3">stravis(3)</a> to
sanitize redirect URIs from <a
href="https://man.openbsd.org/ftp.1">ftp(1)</a> fetch before printing.
<li>Prevent an <a
href="https://man.openbsd.org/unwind.8">unwind(8)</a> crash when a TCP
query is larger than the length field indicated.
<li>Preserve the original order of nameservers as configured via <a
href="https://man.openbsd.org/resolv.conf.5">resolv.conf(5)</a> in <a

<li>Restrict the characters allowed in the hostname argument of <a
href="https://man.openbsd.org/getaddrinfo.3">getaddrinfo(3)</a> to the
set [A-z0-9-_.]. Additionally, two consecutive dots ('.') are not
allowed nor can the string start with - or '.'. This removes
characters like '$', '`', '\n' or '*' that can traverse the DNS
without problems but have special meaning as in a shell.
<li>Fixed a number of out of bounds reads in DNS response parsing of
the async DNS resolver in libc.
<li>Added <a
href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a> -M (mac) to
find the mac address on an interface and print it.
<li>Added support for configuring interfaces by lladdr to support
interface configurations bound to a specific hardware device. The "if"
part of the <a
href="https://man.openbsd.org/hostname.if.5">hostname.if(5)</a>
configuration file can now be a MAC address.
<li>Limited display of wireguard peers by <a
href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a> to when
either a wireguard interface is specified or the flag "-A" is used.
<li>Implemented the RFC 8781 PREF64 router advertisement option in
<a href="https://man.openbsd.org/rad.8">rad(8)</a> which is used to
communicate NAT64 prefixes to hosts.
<li>Moved the documentation of flag mappings displayed by "route show" from the <a
href="https://man.openbsd.org/netstat.1">netstat(1)</a> manpage to <a
href="https://man.openbsd.org/route.8">route(8)</a>.
<li>Improvements in <a href="https://man.openbsd.org/nc.1">nc(1)</a>:
<ul>
<li>Stop claiming connection success in UDP mode unless true.
<li>Do not test the connection in non-interactive mode. The test
writes characters to the socket which can corrupt data that is
possibly piped into nc.
<li>Some refactoring and code cleanup.
</ul>
<li>Improvements in
<a href="https://man.openbsd.org/acme-client.1">acme-client(1)</a>:
<ul>
<li>Added support for newlines inside the alternative names block in
<a href="https://man.openbsd.org/acme-client.conf.5">acme-client.conf(5)</a>.
<li>Use proper data structures for retrieving subject alternative names in
certificates rather than printing them to a buffer and tokenizing and
parsing the undocumented string.
<li>Simplified, corrected and modernized the use of libcrypto interfaces.
<li>Plugged various memory leaks.
<li>Use <a href="https://man.openbsd.org/ASN1_TIME_to_tm.3">ASN1_TIME_to_tm(3)</a>
instead of a poor man's hand-rolled version of it.
<li>Use <a href="https://man.openbsd.org/acme-client.1">timegm(3)</a>
instead of <a href="https://man.openbsd.org/acme-client.1">mktime(3)</a>
to eliminate time-zone variation.
<li>Encode Subject Alternative Name (SAN) entries before printing.
<li>Prevent <a href="https://man.openbsd.org/acme-client.1">acme-client(1)</a>
from leaking an http get request when receiving a redirect without a
location header.
</ul>
<!-- smtpd -->
<li>Prevented <a href="https://man.openbsd.org/smtpd.8">smtpd(8)</a>
abort due to a connection from a local, scoped ipv6 address.
<li>Fixed a potential NULL dereference in the unpriv child expanding
%{mda} in <a href="https://man.openbsd.org/smtpd.8">smtpd(8)</a>.
<li>Corrected the order of arguments for calls to <a
href="https://man.openbsd.org/shutdown.2">shutdown(2)</a> on the route
socket of <a href="https://man.openbsd.org/slaacd.8">slaacd(8)</a>, <a
href="https://man.openbsd.org/dhcpleased.8">dhcpleased(8)</a> and <a
href="https://man.openbsd.org/unwind.8">unwind(8)</a>.
<li>Made <a href="https://man.openbsd.org/route.8">route(8)</a>
sourceaddr print the used addresses for inet and inet6, or "default"
if no sourceaddr is set and the default algorithm is used.
<li>Added -mpls option to the route(8) monitor command. It can be
used to restrict displayed route messages to the mpls address family.
<li>Fixed <a href="https://man.openbsd.org/openrsync.1">rsync(1)</a>
handling of port numbers in rsync://host[:port]/module URLs.
<li>Made <a href="https://man.openbsd.org/tcpdrop.8">tcpdrop(8)</a>
accept netstat-style address.port syntax.
<li>Ensured <a href="https://man.openbsd.org/pfctl.8">pfctl(8)</a>
correctly adds addresses to the undefined/inactive table.
<li>Switched <a href="https://man.openbsd.org/tftpd.8">tftpd(8)</a> to default
to read-only unless <code>-w</code> is specified for write access
(the previous default).
<li>Changed <a href="https://man.openbsd.org/rarpd.8">rarpd(8)</a> to only unveil /tftpboot if -t is specified.
<li>Fixed the DIOCIGETIFACES ioctl so all network interfaces and
interface groups are reported in <a
href="https://man.openbsd.org/pfctl.8">pfctl(8)</a>.
</ul>
<li><a href="https://man.openbsd.org/tmux.1">tmux(1)</a> improvements and bug fixes:
<ul>
<li>Added scroll-top and scroll-bottom <a href="https://man.openbsd.org/tmux.1">tmux(1)</a> commands to scroll so cursor is at the top or bottom respectively.
<li>Added a -T flag to <a href="https://man.openbsd.org/tmux.1">tmux(1)</a> capture-pane to capture up to the last used cell and not the full width of the pane.
<li>Preserved the marked pane when renumbering windows in <a href="https://man.openbsd.org/tmux.1">tmux(1)</a>.
<li>Added modified tab key sequences to <a href="https://man.openbsd.org/tmux.1">tmux(1)</a>.
<li>Changed <a href="https://man.openbsd.org/tmux.1">tmux(1)</a> to only set the extended flag when searching, which allows send-keys to work.

<li>Made <a href="https://man.openbsd.org/tmux.1">tmux(1)</a> tty-keys accept \007 as terminator to OSC 10 or 11.
<li>Made <a href="https://man.openbsd.org/tmux.1">tmux(1)</a> recognize pasted texts wrapped in bracket paste sequences, rather than only forwarding to the program inside.
<li>Supported -1 without -N for list-keys in <a href="https://man.openbsd.org/tmux.1">tmux(1)</a>.
<li>Added a flag to <a href="https://man.openbsd.org/tmux.1">tmux(1)</a> display-menu to select the menu item chosen first.

</ul>
</ul>
<li>OpenSSH 9.3 and OpenSSH 9.2<br>
This release of OpenBSD includes the changes made to OpenSSH since release 9.1:
<ul>
<li>Security
<ul>
<li>ssh-add(1): when adding smartcard keys to ssh-agent(1) with the
per-hop destination constraints (ssh-add -h ...) added in OpenSSH
8.9, a logic error prevented the constraints from being
communicated to the agent. This resulted in the keys being added
without constraints. The common cases of non-smartcard keys and
keys without destination constraints are unaffected. This problem
was reported by Luci Stanescu.
<li>ssh(1): Portable OpenSSH provides an implementation of the
getrrsetbyname(3) function if the standard library does not
provide it, for use by the VerifyHostKeyDNS feature. A
specifically crafted DNS response could cause this function to
perform an out-of-bounds read of adjacent stack data, but this
condition does not appear to be exploitable beyond denial-of-service
to the ssh(1) client.<br>
The getrrsetbyname(3) replacement is only included if the system's
standard library lacks this function and portable OpenSSH was not
compiled with the ldns library (--with-ldns). getrrsetbyname(3) is
only invoked if using VerifyHostKeyDNS to fetch SSHFP records. This
problem was found by the Coverity static analyzer.
<li>sshd(8): fix a pre-authentication double-free memory fault
introduced in OpenSSH 9.1. This is not believed to be exploitable,
and it occurs in the unprivileged pre-auth process that is
subject to chroot(2) and is further sandboxed on most major
platforms.
<li>ssh(8): in OpenSSH releases after 8.7, the PermitRemoteOpen option
would ignore its first argument unless it was one of the special
keywords "any" or "none", causing the permission list to fail open
if only one permission was specified. bz3515
<li>ssh(1): if the CanonicalizeHostname and CanonicalizePermittedCNAMEs
options were enabled, and the system/libc resolver did not check
that names in DNS responses were valid, then use of these options
could allow an attacker with control of DNS to include invalid
characters (possibly including wildcards) in names added to
known_hosts files when they were updated. These names would still
have to match the CanonicalizePermittedCNAMEs allow-list, so
practical exploitation appears unlikely.
</ul>
<li>Potentially-incompatible changes
<ul>
<li>ssh(1): add a new EnableEscapeCommandline ssh_config(5) option that
controls whether the client-side ~C escape sequence that provides a
command-line is available. Among other things, the ~C command-line
could be used to add additional port-forwards at runtime.<br>
This option defaults to "no", disabling the ~C command-line that
was previously enabled by default. Turning off the command-line
allows platforms that support sandboxing of the ssh(1) client
(currently only OpenBSD) to use a stricter default sandbox policy.
</ul>
<li>New features
<ul>
<li>ssh-keygen(1), ssh-keyscan(1): accept -Ohashalg=sha1|sha256 when
outputting SSHFP fingerprints to allow algorithm selection. bz3493
<li>sshd(8): add a `sshd -G` option that parses and prints the
effective configuration without attempting to load private keys
and perform other checks. This allows usage of the option before
keys have been generated and for configuration evaluation and
verification by unprivileged users.
<li>sshd(8): add support for channel inactivity timeouts via a new
sshd_config(5) ChannelTimeout directive. This allows channels that
have not seen traffic in a configurable interval to be
automatically closed. Different timeouts may be applied to session,
X11, agent and TCP forwarding channels.
<li>sshd(8): add a sshd_config UnusedConnectionTimeout option to
terminate client connections that have no open channels for a
length of time. This complements the ChannelTimeout option above.
<li>sshd(8): add a -V (version) option to sshd like the ssh client has.
<li>ssh(1): add a "Host" line to the output of ssh -G showing the
original hostname argument. bz3343
<li>scp(1), sftp(1): add a -X option to both scp(1) and sftp(1) to
allow control over some SFTP protocol parameters: the copy buffer
length and the number of in-flight requests, both of which are used
during upload/download. Previously these could be controlled in
sftp(1) only. This makes them available in both SFTP protocol
clients using the same option character sequence.
<li>ssh-keyscan(1): allow scanning of complete CIDR address ranges,
e.g. "ssh-keyscan 192.168.0.0/24". If a CIDR range is passed, then
it will be expanded to all possible addresses in the range
including the all-0s and all-1s addresses. bz#976
<li>ssh(1): support dynamic remote port forwarding in escape
command-line's -R processing. bz#3499
</ul>
<li>Bugfixes
<ul>
<li>scp(1), sftp(1): fix progressmeter corruption on wide displays;
bz3534
<li>ssh-add(1), ssh-keygen(1): use RSA/SHA256 when testing usability
of private keys as some systems are starting to disable RSA/SHA1
in libcrypto.
<li>sftp-server(8): fix a memory leak. GHPR363
<li>ssh(1), sshd(8), ssh-keyscan(1): remove vestigial protocol
compatibility code and simplify what's left.
<li>Fix a number of low-impact Coverity static analysis findings.
These include several reported via bz2687
<li>ssh_config(5), sshd_config(5): mention that some options are not
first-match-wins.
<li>Rework logging for the regression tests. Regression tests will now
capture separate logs for each ssh and sshd invocation in a test.
<li>ssh(1): make `ssh -Q CASignatureAlgorithms` work as the manpage
says it should; bz3532.
<li>ssh(1): ensure that there is a terminating newline when adding a
new entry to known_hosts; bz3529
<li>ssh(1): when restoring non-blocking mode to stdio fds, restore
exactly the flags that ssh started with and don't just clobber them
with zero, as this could also remove the append flag from the set.
bz3523
<li>ssh(1): avoid printf("%s", NULL) if using UserKnownHostsFile=none
and a hostkey in one of the system known hosts file changes.
<li>scp(1): switch scp from using pipes to a socket-pair for
communication with its ssh sub-processes, matching how sftp(1)
operates.
<li>sshd(8): clear signal mask early in main(); sshd may have been
started with one or more signals masked (sigprocmask(2) is not
cleared on fork/exec) and this could interfere with various things,
e.g. the login grace timer. Execution environments that fail to
clear the signal mask before running sshd are clearly broken, but
apparently they do exist.
<li>ssh(1): warn if no host keys for hostbased auth can be loaded.
<li>sshd(8): Add server debugging for hostbased auth that is queued and
sent to the client after successful authentication, but also logged
to assist in diagnosis of HostbasedAuthentication problems. bz3507
<li>ssh(1): document use of the IdentityFile option as being usable to
list public keys as well as private keys. GHPR352
<li>sshd(8): check for and disallow MaxStartups values less than or
equal to zero during config parsing, rather than failing later at
runtime. bz3489
<li>ssh-keygen(1): fix parsing of hex cert expiry times specified on
the command-line when acting as a CA.
<li>scp(1): when scp(1) is using the SFTP protocol for transport (the
default), better match scp/rcp's handling of globs that don't match
the globbed characters but do match literally (e.g. trying to
transfer a file named "foo.[1]"). Previously scp(1) in SFTP mode
would not match these pathnames but legacy scp/rcp mode would.
bz3488
<li>ssh-agent(1): document the "-O no-restrict-websafe" command-line
option.
<li>ssh(1): honour user's umask(2) if it is more restrictive then the
ssh default (022).

<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>install73.iso</i> or
<i>cd73.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>install73.iso</i> or
<i>cd73.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>install73.img</i> or
<i>miniroot73.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>install73.img</i> or <i>miniroot73.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>install73.iso</i> or
<i>cd73.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>install73.img</i> or
<i>miniroot73.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>miniroot73.img</i> to the start of the CF
or disk, and boot normally.
<h3>OpenBSD/loongson:</h3>
<p>
Write <i>miniroot73.img</i> to a USB stick and boot bsd.rd from it
or boot bsd.rd via tftp.
Refer to the instructions in INSTALL.loongson for more details.
<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
/7.3/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>install73.img</i> or <i>miniroot73.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>install73.img</i> or <i>miniroot73.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>floppy73.img</i> or <i>floppyB73.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>miniroot73.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 7.2 system, and do not want to reinstall,
upgrade instructions and advice can be found in the
<a href="faq/upgrade73.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_3</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 7.3 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.
