------------------------------------------------------------------------
- OpenBSD 7.4 RELEASED -------------------------------------------------
October 16, 2023.
We are pleased to announce the official release of OpenBSD 7.4.
This is our 55th release. We remain proud of OpenBSD's record of more
than twenty years with only two remote holes in the default install.
As in our previous releases, 7.4 provides significant improvements,
including new features, in nearly all areas of the system:
- Various kernel improvements:
o On arm64, show BTI and SBSS features in dmesg(8).
o New kqueue1(2) system call supporting the O_CLOEXEC flag.
o Map device tree read/write to unbreak root on softraid(4).
o Correctly recognize umass(4) floppy disk devices as floppy disks.
o In wscons(4), catch up with box drawing characters which have been
standardized in unicode after the original wscons code was written
and chose placeholder values.
o In wscons(4), make sure we do not increase the escape sequence
argument count beyond usable bounds.
o Implement dt(4) utrace(2) support on amd64 and i386.
o Correct undefined behavior when using MS-DOS filesystems, fixes
imported from FreeBSD.
o Make the softdep mount(8) option a no-op. Softdep was a
significant impediment to improving the vfs layer.
o Allow unveil(2)ed programs to dump core(5) into the current
working directory.
o Address incomplete validation of ELF program headers in execve(2).
o On arm64, use the deep idle state available on Apple M1/M2 cores
in the idle loop and for suspend, resulting in power savings.
o Update AMD CPU microcode if a newer patch is available.
o Enable a workaround for the 'Zenbleed' AMD CPU bug.
o Report speculation control bits in dmesg(8) CPU lines.
o To give the primary CPU an opportunity to perform clock interrupt
preparation in a machine-independent manner we need to separate
the "initialization" parts of cpu_initclocks() from the "start the
clock interrupt" parts. Separate cpu_initclocks() from
cpu_startclock().
o Fix a problem where CPU time accounting and RLIMIT_CPU was
unreliable on idle systems.
o Improve the output of the "show proc" command of the kernel
debugger ddb(4) and show both the PID and TID of the proc.
- SMP Improvements
o Rewrite pfsync(4), in particular to improve locking and to help
with unlocking more of pf(4) and with parallelisation of the
network stack in the future. The protocol remains compatible with
the older version.
o Remove kernel locks from the ARP input path.
o Pull MP-safe arprequest() out of kernel lock.
o Remove the kernel lock from IPv6 neighbor discovery.
o Unlock more parts of ioctl(2) and the routing code in the network
stack.
- Direct Rendering Manager and graphics drivers
o Update drm(4) to Linux 6.1.55.
o Don't change end marker in sg_set_page(). Caused bad memory
accesses when using page flipping on Alder Lake and Raptor Lake.
- VMM/VMD improvements
o Allowed vmm(4) guests to enable and use supervisor IBT.
o Suppressed AMD hardware p-state visibility to vmm(4) guests.
o Avoid use of uninitialised memory in vmd(8).
o Migrate vmd_vm.vm_ttyname to char array allowing a vmd_vm object
to be transmitted over an ipc channel.
o Cleaned up file descriptor closing in vmd(8) vmm process.
o Fixed vm send/receive, restoring device virtqueue addresses on
receive.
o Introduced execvp(3) after fork for child vm processes.
o No longer generate an error in vmd(8) if vm.conf(5) is absent.
o Split vmm(4) into MI/MD parts.
o Introduced multi-process model for vmd(8) virtio block and network
devices.
o Allowed vm owners to override boot kernel when using vmctl(8) to
start a vm.
o Changed staggered start of vms to number of online CPUs.
o Fixed a segfault on vm creation.
o Switched to anonymous shared memory mappings for vmd(8) vm
processes, introducing a new vmm(4) ioctl(2).
o Relaxed absolute path requirements for vmd(8) configtest mode
(-n).
o Adjusted shutdown logic by vm id to function similarly as by name.
o Moved validation of local network prefixes for the internal vmd(8)
DHCP service into the config parser.
o Fixed QCOW2 base images when used with the vmd(8) multi-process
device model.
o Fixed setting verbose logging in child processes.
o Fixed a race condition related to the emulated i8259 interrupt
controller by ignoring interrupt masks on assert.
o Inlined pending interrupts in the vmm(4) ioctl(2) for running the
vcpu, reducing vm latency.
o Added zero-copy, vectored io to the vmd(8) virtio block device.
o Changed to logging vmd(8) vm ids in the vcpu run loop on error and
not the ids used by vmm(4).
o Fixed a vm pause deadlock.
o Changed vmd(8) logging format to disambiguate vm and device
process by names and indices.
o Fixed dynamically toggling verbose logging mode with vmctl(8).
- Various new userland features:
o New ISO C11 header <uchar.h> declaring the types char32_t and
char16_t and the functions c32rtomb(3), mbrtoc32(3), c16rtomb(3),
and mbrtoc16(3).
o Introduce a new malloc(3) option D for memory leak detection with
ktrace(1) and kdump(1).
o Support ${.VARIABLES} in make(1), listing the names of all global
variables that have been set.
o New kdump(1) -u option to select utrace(2) tracepoints by label.
o In openrsync(1), support the options --size-only and
--ignore-times.
o Update zoneinfo to tzdata2023c.
o Accept the ucom(4) fixed name format as a valid format for the
cu(1) -l option.
o In cron(8) and crontab(5), add support for random offsets when
using ranges with a step value in cron. This extends the random
range syntax to support step values. Instead of choosing a random
number between the high and low values, the field is treated as a
range with a random offset less than the step value. This can be
used to avoid thundering herd problems where multiple machines
contact a server all at the same time via cron jobs.
o Extend and improve the ibuf API in libutil and add functions for
more specific data types, for modifying data at specific offsets,
for getting and setting the file descriptor stored on the ibuf and
for efficient wrapping of ibufs into imsgs. The ibuf API is mostly
used in network daemons.
o In wsconsctl(8), add button mappings for two- and three-finger
clicks on clickpads.
- Various bugfixes and tweaks in userland:
o In pax(1) and tar(1), do not open files that will be skipped,
speeding up archive creation when many files are skipped.
o In pax(1), tar(1), and cpio(1) terminal output, escape
non-printable characters in messages that may include file names,
and truncate times to the correct maximum value.
o Better diagnostics from make(1) when a makefile exists but cannot
be opened.
o Prevent a buffer underflow in patch(1) that could occur with lines
longer than 32kB.
o Prevent a segmentation fault in patch(1) that occurred when a
patch specified a file name so long that basename(3) failed.
o Prevent a read buffer overrun in patch(1) that could occur when a
patch specified a file name ending in a slash.
o Let stat(1) correctly print mtimes after 2038.
o Refactoring and documenting of fdisk(8) code, to make it easier to
maintain.
o fdisk(8) no longer adds extra blanks at the end of lines,
eliminating spurious line wrapping.
o In clang(1), allow out-of-class defaulting of comparison
operators, by ways of backporting an upstream commit.
o Many changes in mg(1):
- New command set-tab-width to change the tabulator width on a
per-buffer basis.
- Let the space-to-tabstop command move to the right position
even if the line contains tabs, control characters, or
non-ASCII bytes.
- Fall back to /bin/sh if $SHELL is undefined.
- Fix parsing of tag files with duplicate entries. Instead of
erroring out, ignore duplicates. Fixes using
/var/db/libc.tags again.
- Change the visit-tags-table command to immediately load the
tag file, and drop the lazy mechanics.
- Do not leak memory in pop-tag-mark if it fails to switch
buffers.
- Fix a read buffer overrun caused by -u arguments longer than
1023 bytes.
- Fix a write buffer overrun on the stack caused by
blink-and-insert matching a very long line that is not
currently visible in the window.
- Skip checking permissions of conffile with access(2).
- Resurrect no-tab-mode and add it to the list of modes that
can be set with set-default-mode.
o Fix a segfault when the disklabel(8) simple editor encounters an
incomplete partition line.
o Fix disklabel(8) handling of templates with partitions after a
"N-* 100" entry.
o Enable disklabel(8) regress tests to work on sparc64.
o Fix fdisk(8) initialization of CHS/LBA fields in an MBR, allowing
machines with a BIOS that uses CHS to boot from disks >8G.
o Retire disklabel(8) -E expert mode.
o When displaying GPT partition attributes fdisk(8) prefixes
Microsoft partition attribute names with 'MS'.
o In the absence of the 'disktype' command line parameter
disklabel(8) always uses the current media type provided by the
kernel.
o Ensure fdisk(8) handles the case where a GPT partition name is not
a valid C string.
o When creating new crypto volumes with bioctl(8), by default use a
hardware based number of KDF rounds for passphrases.
o Let bioctl(8) gracefully prompt again during interactive creation
and passphrase change on CRYPTO and 1C volumes.
o Let bioctl(8) read passphrases without prompts or confirmation in
-s mode, allowing non-interactive use.
o Allow the atactl(8) command readattr to succeed even for disks
where ATA_SMART_READ and ATA_SMART_THRESHOLD revisions mismatch,
as long as checksums are OK.
o In ld.so(1), treat symlinks in $ORIGIN determination the same way
as other OS linkers do.
o In ld.so(1), avoid an overflow in the ELF SYSV ABI hash function.
o Make sure modf(3) and modff(3) return correct values for
infinities.
o Do not fail in ober_scanf_elements(3) when encountering empty
sequences.
o Remove broken special handling of test -t in ksh(1).
o The caching mechanism used by pkg_add(1) to speed up pkg_add -u
now also works if -stable packages are available.
o Significantly increase the speed of pkg-config(1).
o In seq(1), fix a check for rounding error and truncation.
o In cron(8), introduce upstream fixes in the handling of @yearly,
@monthly, @weekly, @daily and @hourly entries.
o Fix a bug in cron(8) where whitespace after usernames would not be
completely skipped while parsing the crontab(5) file.
o Make rcctl(8) check if a daemon exists before trying to disable
it, thereby avoiding parsing and printing of bogus characters.
o Print to the console the fingerprint of a newly generated ssh(1)
host key of the preferred type (currently ED25519), typically when
booting for the first time. This simplifies a secure first ssh
connection to a freshly installed machine.

o Add support for the RK3568 32k RTC, RK3588, and other clocks in
rkclock(4).
o In dwpcie(4), attach Baikal-M PCIe.
o In openfirmware, implement regulator notifiers which get called
when the voltage/current for a regulator is changed or when the
regulator gets initialized when it attaches for the first time.
The latter makes it possible to register a notifier for a
regulator that hasn't attached yet.
o Ignore duplicate ACPI lid transitions as they can happen on Dell
Precision 5510 systems.
o Make RK3568 PCIe controllers run at the maximum possible speed by
using dwpcie_link_config() when initializing.

o Support thermal sensors on Ryzen 9 79xx in ksmn(4).
o Add support for JH7110 to dwmmc(4), making eMMC and microSD mostly
work on the Starfive VisionFive 2.
o Add support for the RK3588 PCIe3 PHY to rkpciephy(4). The PHY
controls 4 lanes that can be routed to 4 of 5 PCIe controllers.
o Add mute control to sncodec(4). This makes the mute button work on
laptops using this driver.

laptops that use tascodec(4) work.
o Improve the suspend/resume behavior of several drivers, reducing
power consumption during suspend.
o Add support for the Synopsys DesignWare I2C controller (dwiic(4))
and the X-Powers AXP Power Management IC (axppmic(4)).
o Enable the mbg(4) timedelta sensor on amd64 and match the Meinberg
PZF180PEX.
- New or improved network hardware support:
o Fix dwqe(4) on several boards that use rgephy(4) by configuring
the RGMII interface before taking the PHY out of reset.
o Improve dwqe(4) and determine PHY mode and pass the appropriate
flags down to the PHY when attaching.
o Report in dmesg(8) on which gmac the dwqe(4) driver is attaching
to.
o Document that Intel i226 adapters are supported by igc(4).
o Add ngbe(4), a driver for WangXun WX1860 PCI Express 10/100/1Gb
Ethernet devices. Also support it on amd64 install media.
o Add support for the RTL8211F-VD PHY in rgephy(4).
o In openfirmware, add glue for network interfaces to be found by
fdt/ofw node or phandle in order to support "switch chips" like
the marvell link street.
o Add support for RTL8153D devices to ure(4).
o Provide byte and packet counter statistics in some dwge(4)
implementations.
o On bge(4), make hardware counters available via kstats for BCM5705
and newer controller chips.
o Make several improvements to vmx(4), the VMware VMXNET3 Virtual
Interface Controller.
o In em(4), stop putting multicast addresses into the Receive
Address Registers. Instead hash them all into the Multicast Table
Array.
o Support Mellanox ConnectX-6 Lx in mcx(4).
o In mcx(4), add 100GB LR4 Ethernet capability and map it to
IFM_100G_LR4.
o Add initial support for Atlantic 2 hardware in aq(4).
- Added or improved wireless network drivers:
o Improve how Quectel LTE&5G devices attach to umb(4).
- IEEE 802.11 wireless stack improvements and bugfixes:
o Add support for RTL8188FTV devices to the urtwn(4) driver.
o Attach Intel wireless devices with PCI product ID 0x51f1 to
iwx(4).
o Fix a bug where iwm(4) and iwx(4) background scan tasks were added
to the wrong task queue.
o Fix a firmware error that occurred when an iwx(4) interface was
brought down.
o Fix iwx(4) firmware errors triggered during background scans.
o Fix a crash in the iwm(4) driver when userland attempts to inject
frames via bpf in monitor mode.
- Installer, upgrade and bootloader improvements:
o In the arm64 ramdisk, simplify apple firmware copying to make it
easier to add new firmware.
o On armv7 and arm64, silence informational messages from dd(1) when
zeroing a disk's first 1MB. Use character not block devices with
dd(1) like on other architectures.
o Refactor the code of md_installboot() on armv7 and arm64 to be
more in line with other architectures.
o Improve the dialogue of the installer without affecting
autoinstall(8) files.
o Enable ufshci(4) on arm64 install media.
o On arm64 pine64 boards, stop writing pine64 firmware to disk.
o When media has neither a GPT nor an MBR installboot(8), assume
OpenBSD occupies the entire disk starting at sector 0.
o Attempt to not overflow the ramdisk when extracting firmware on
Apple arm64 systems.
o Add support for loading files from the EFI System Partition.
o Fix a bug in the handling of SCSI drives in the bootloader on the
luna88k architecture.
o On luna88k, implement the chmod() signaling mechanism for
/bsd.upgrade to prevent re-upgrade, like other architectures.
o Support for softraid(4) disks in the installer was improved:
- Make root on softraid(4) installations boot out of the box on
Raspberry Pis (arm64).
- Support installations with root on softraid(4) on arm64,
tested on Pinebook Pro, Raspberry Pi 4b, and SolidRun CEX7.
- On riscv64, enable softraid(4) in the ramdisk kernel and
support installations with root on softraid(4)
- When installing on encrypted softraid(4), determine the disk
for placing the root device automatically and make it default
as it is the only legit choice.
- Add arm64 to the list of architectures with support for
guided disk encryption.
- Retain existing EFI System partitions on systems with APFSISC
partitions (arm64 Apple M1/M2) during installation with root
on softraid(4).
- Enable softraid(4) in ramdisk on the powerpc64 architecture.
- Security improvements:
o Enable indirect branch tracking (IBT) on amd64 and branch target
identification (BTI) on arm64 in both the kernel and in userland.
On hardware that supports this feature, it helps enforcing control
flow integrity by making sure malicious code cannot jump into the
middle of a function.
o On the arm64 architecture, enable pointer authentication (PAC) in
userland on those machines where it works correctly. It helps
enforcing control flow integrity by making sure malicious code
cannot manipulate a function's return address.
o Together with retguard these two features protect against ROP
attacks. Compiler defaults for base clang, ports clang and ports
gcc (as well as some other non-C language family compilers in
ports) have been changed to enable these features by default. As a
result the vast majority of programs on OpenBSD (and all programs
in the base system) run with these security features enabled.
o Change malloc(3) chunk sizes to be fine grained: chunk sizes are
closer to the requested allocation size.
o In malloc(3), check all chunks in the delayed free list for
write-after-free.
o The shutdown(8) program can now only be executed by members of the
new _shutdown group. The idea is that system administrators can
now remove most users from the excessively powerful operator
group, which in particular provides read access to disk device
nodes.
o Using unveil(2), restrict patch(1) filesystem access to the
current directory including subdirectories, TMPDIR, and file names
given on the command line.
o In ksh(1), consistently escape control characters when displaying
file name completions, even when there are multiple matches.
- Changes in the network stack:
o Sync the use of getuptime(9) in the Neighbour Discovery (ND) code
with ARP.
o In the IPv6 forwarding code, call getuptime(9) once for
consistency with IPv4.
o ARP has a queue of packets that should be sent after name
resolution. Neighbor discovery (ND6) did only hold a single
packet. Unified the code, added a queue to ND6 and made the code
MP safe.
o Implement a new sysctl(2) net.inet6.icmp6.nd6_queued to show the
number of packets waiting for an ND6 response, analogous to ARP.
o When configuring a new IPv6 address on an interface, an upstream
router doesn't know where to send traffic. Send an unsolicited
neighbor advertisement, as described in RFC9131, to the
all-routers multicast address so all routers on the same link will
learn the path back to the address.
o Implement the inbound portion of RFC9131. Let routers create new
neighbor cache entries when receiving valid neighbor
advertisements.
o Initial support for TCP segmentation offload (TSO) and TCP large
receive offload (LRO) was implemented:
- If the driver of a network interface supports TSO, do not
chop the packet in the network stack, but pass it down to the
interface layer for TSO.
- Provide a software TSO implementation, to be used as a
fallback if network hardware does not support TSO.
- Provide a new sysctl(2) node net.inet.tcp.tso such that TSO
can be globally disabled. By default, it is enabled on all
interfaces supporting it.
- In ifconfig(8), display separate hwfeatures for TSOv4, TSOv6,
and LRO and provide a -tcplro parameter to disable LRO on a
per-interface basis.
- Enable TSO and forwarding of LRO packets via TSO in ix(4).
- In ix(4), allocate less memory for tx buffers.
- Speed up TCP transfer on lo(4) interfaces by using TSO and
LRO.
- Enable LRO per default in network drivers. LRO allows to
receive aggregated packets larger than the MTU. Receiving TCP
streams becomes much faster. Currently only ix(4) and lo(4)
devices support LRO, and ix(4) is limited to IPv4 and
hardware newer than the old 82598 model.
o The following changes were made to the pf(4) firewall:
- Speed up the ioctl(2) request DIOCGETRULE such that pfctl(8)
can retrieve all pf(4) rules from the kernel in linear rather
than in quadratic time. To protect the kernel from memory
exhaustion, userland processes now have to release tickets
obtained with DIOCGETRULES by issuing the new ioctl(2)
request DIOCXEND. In particular, snmpd(8) and systat(1) now
do that.
- Relax the implementation of the pass all rule so all forms of
neighbor advertisements are allowed in either direction.
- When redirecting locally generated IP packets to userland
with divert-packet rules, the packets may have no checksum
due to hardware offloading. Calculate the checksum in that
case.
- Fix a bug where nat-to could fail to insert a state due to
conflict on chosen source port number.
- No longer ignore keep state and nat-to actions for
unsolicited ICMP error responses. Tighten the rule matching
logic so ICMP error responses no longer match keep state
rule. In typical scenarios, ICMP errors (if solicited) should
match existing state. The change is going to bite firewalls
which deal with asymmetric routes. In those cases the keep
state action should be relaxed to sloppy or new no state rule
to explicitly match ICMP errors should be added.
o Do not calculate IP, TCP, and UDP checksums on lo(4) interfaces.
o Convert the tcp_now() time counter to 64 bits to avoid 32 bits
wrap around after changing tcp_now() ticks to milliseconds.
o Add initial support for route-based IPsec VPNs.
Rather than use IPsec flows (aka, entries in the IPsec security
policy database) to decide which traffic should be encapsulated in
IPsec and sent to a peer, this changes security associations (SAs)
so they can also refer to a tunnel interface. When traffic is
routed over that tunnel interface, an IPsec SA is looked up and
used to encapsulate traffic before being sent to the peer on the
SA. When traffic is received from a peer using an interface SA,
the specified interface is looked up and the packet is handed to
it so it looks like packets come out of the tunnel.
o Add sec(4) to support route-based IPsec VPNs.
o Introduce reference counting for TCP syn cache entries.
o Have wg(4) copy the priority from the inner packet to the outer
encrypted packet, so that higher priority packets are picked from
hfsc queues for earlier transmission.
- Routing daemons and other userland network improvements:
o IPsec support was improved:
- In iked(8), support route-based sec(4) tunnels.
- In iked(8), add support to verify X.509 chain from CERT
payloads.
- In iked(8), do not leak memory when receiving a CERT payload
for pubkey auth or for an invalid CERT Encoding.
- In iked(8), do not leak a file descriptor if
open_memstream(3) fails while trying to enable a child SA.
- While trying to verify an ECDSA signature in iked(8),
correctly detect failure of DER encoding with
i2d_ECDSA_SIG(3).
- In ipsecctl(8), support route-based IPsec VPN negotiation
with sec(4).
- In isakmpd(8), support configuring interface SAs for
route-based IPsec VPNs.
- In isakmpd(8) quick mode, do not crash with a NULL pointer
access when a group description is specified but it is
invalid, unsupported, or memory allocation or key generation
fails.
- In isakmpd(8), avoid a double free in the unlikely event that
EC_KEY_check_key(3) fails right after generating a new key
pair.
- Allow building isakmpd(8) with a libcrypto library that has
binary field support ("GF2m") removed.
o In bgpd(8),
- Add first version of flowspec support. Right now only
announcement of flowspec rules is possible.
- Update ASPA support to follow
draft-ietf-sidrops-aspa-verification-16 and
draft-ietf-sidrops-aspa-profile-16 by making the ASPA lookup
tables AFI-agnostic.
- Rework UPDATE message generation to use the new ibuf API
instead of the hand-rolled solution before.
- Fix ext-community * * matching which also affects filters
removing all ext-communities.
- Improve and extend the bgpctl parser to handle commands like
bgpctl show rib 192.0.2.0/24 detail. Also add various
flowspec specific commands.
- Introduce a semaphore to protect intermittent RTR session
data from being published to the RDE.
- Limit the socket buffer size to 64k for all sessions.
Limiting the buffer size to a reasonable size ensures that
not too many updates end up queued in the TCP stack.
- Adjust example GRACEFUL_SHUTDOWN filter rule in the example
config to only match on ebgp sessions.
o rpki-client(8) saw some changes:
- A 30%-50% performance improvement was achieved through
libcrypto's partial chains certificate validation feature.
Already validated non-inheriting CA certificates are now
marked as trusted roots. This way it can be ensured that a
leaf's delegated resources are properly covered, and at the
same time most validation paths are significantly shortened.
- Support for gzip and deflate HTTP Content-Encoding
compression was added. This allows web servers to send RRDP
XML in compressed form, saving around 50% of bandwidth.
- ASPA support was updated to
draft-ietf-sidrops-aspa-profile-16. As part of supporting
AFI-agnostic ASPAs, the JSON syntax for Validated ASPA
Payloads changed in both filemode and normal output.
- In filemode (-f option) the applicable manifests are now
shown as part of the signature path.
- A new -P option was added to manually specify a moment in
time to use when parsing the validity window of certificates.
Useful for regression testing. Default is invocation time of
rpki-client.
- The -A option will now also exclude ASPA data from the JSON
output.
- The synchronisation protocol used to sync the repository is
now included in the OpenMetrics output.
- Improved accounting by tracking objects both by repo and tal.
- Check whether products listed on a manifest were issued by
the same authority as the manifest itself.
- File modification timestamps of objects retrieved via RRDP
are now deterministically set to prepare the on-disk cache
for seamless failovers from RRDP to RSYNC.
- Improved detection of RRDP session desynchronization: a check
was added to compare whether the delta hashes associated to
previously seen serials are different in newly fetched
notification files.
- Improved handling of RRDP deltas in which objects are
published, withdrawn, and published again.
- Disallow X.509 v2 issuer and subject unique identifiers in
certs. RPKI CAs will never issue certificates with V2 unique
identifiers.
- A check to disallow duplicate X.509 certificate extensions
was added.
- A check to disallow empty sets of IP Addresses or AS numbers
in RFC 3779 extensions was added.
- A warning is printed when the CMS signing-time attribute in a
Signed Object is missing.
- Warnings about unrecoverable message digest mismatches now
include the manifestNumber to aid debugging the cause.
- A check was added to disallow multiple RRDP publish elements
for the same file in RRDP snapshots. If this error condition
is encountered, the RRDP transfer is failed and the RP falls
back to rsync.
- A compliance check for the proper X.509 Certificate version
and CRL version was added.
- A compliance check was added to ensure CMS Signed Objects
contain SignedData, in accordance to RFC 6488 section 3
checklist item 1a.
- Compliance checks were added for the version, KeyUsage, and
ExtendedKeyUsage of EE certificates in Manifest, TAK, and GBR
Signed Objects.
- A CMS signing-time value being after the X.509 notAfter
timestamp was downgraded from an error to a warning.
- A bug was fixed in the handling of CA certificates which
inherit IP resources.
- A compliance check was added to ensure the X.509 Subject only
contains commonName and optionally serialNumber.
- A compliance check was added to ensure the CMS SignedData and
SignerInfo versions to be 3.
- Fisher-Yates shuffle the order in which Manifest entries are
processed. Previously, work items were enqueued in the order
the CA intended them to appear on a Manifest. However, there
is no obvious benefit to third parties deciding the order in
which things are processed.
o In smtpd(8),
- Swapped link-auth filter arguments to avoid ambiguities with
user names containing a "|" character.
- Bumped smtpd-filters(7) protocol version.
- Fixed potential truncation of filtered data lines.
- Allowed arguments on NOOP.
o Many other changes in various network programs and libraries:
- Allow libpcap to read files with some additional link-layer
type values.
- Let pcap_fopen_offline(3) correctly interpret some LINKTYPE_*
values in pcap headers written on foreign operating systems.
- Make dig(1) use less deprecated LibreSSL API.
- Remove stylistic differences between arp(8) and ndp(8)
delete() function. This makes it easier to spot real changes
in behavior.
- Make ndp(8) not remove cloning routes when no neighbor entry
is found with ndp -d.
- Improved error handling in the asr resolver.
- In unwind(8), handle SERVFAIL results on name resolution
better.
- In unwind(8), fix a use-after-free bug triggered by fatal
write errors while sending TCP responses.
- In the router advertisement daemon rad(8), update the default
timers for prefix preferred and valid lifetimes to use the
values from RFC 9096.
- In slaacd(8), remove artificial limit of 2 hours on a PIO
lifetime.
- In ypldap(8), reduce memory usage when updating larger
directories.
- Make ypldap(8) more resilient when some servers are
misbehaving: keep trying LDAP servers until full results
arrive rather than just until one accepts the TCP connection.
- New wgdescription parameter to ifconfig(8) to set a string
describing the wg(4) peer.
- Let ifconfig(8) prefix the interface name to many error and
warning messages.
- Make the tlsv1.0 and tlsv1.1 options in relayd(8) do nothing,
as one should use the default tlsv1.2 instead.
- Fix IPv6 routes being changed by relayd(8) with Routers
configuration.
- In dhcrelay6(8), do not ignore the AF_LINK entries of carp(4)
interfaces.
- Improve the config parser of radiusd(8) to better handle
comments, improve error messages and plug a memory leak.
- In radiusd(8), add request or response decoration feature
which is used through the radiusd module interface. This
makes additional modules can modify RADIUS request or
response messages. Also add new "radius_standard" module
which uses this new feature, provides some generic features
like "strip-atmark-realm" which removes the realm part from
the User-Name attribute.
- Allow UDP for built-in inetd(8) services on 127.0.0.1. This
restriction was added in year 2000 due to IPv6 compatible and
mapped addresses. Nowadays our kernel does not support these
IPv6 features and blocks localhost addresses on non-loopback
interfaces. Make IPv4 127.0.0.1/8 and IPv6 ::1 behave
identically and provide local services if configured.
- In spamd(8), log a dummy "" IP address in the unlikely event
that getnameinfo(3) fails.
- tmux(1) improvements and bug fixes:
o For passthrough, don't write to clients attached to different
sessions.
o Add a format to show if there are unseen changes while in a mode.
o Discard mouse sequences that have the right form but actually are
invalid.
o Invalidate cached tty state after changing features since they may
change what the terminal can do and need mouse sequences or
similar to be sent again.
o Add options to change the confirm key and default behaviour of
confirm-before.
o Add an option menu-selected-style to configure the currently
selected menu item.
o Add -c to run-shell to set working directory.
o Add detach-on-destroy previous and next,
o Set visited flag on last windows when linking session.
- LibreSSL version 3.8.2
o Security fixes
- Disabled TLSv1.0 and TLSv1.1 in libssl so that they may no
longer be selected for use.
- BN_is_prime{,_fasttest}_ex() refuse to check numbers larger
than 32 kbits for primality. This mitigates various DoS
vectors.
- Restricted the RFC 3779 code to IPv4 and IPv6. It was not
written to be able to deal with anything else.
o Portable changes
- Extended the endian.h compat header with hto* and *toh
macros.
- Adapted more tests to the portable framework.
- Internal tools are now statically linked.
- Applications bundled as part of the LibreSSL package
internally, nc(1) and openssl(1), now are linked statically
if static libraries are built.
- Internal compatibility function symbols are no longer
exported from libcrypto. Instead, the libcompat library is
linked to libcrypto, libssl, and libtls separately. This
increases size a little, but ensures that the libraries are
not exporting symbols to programs unintentionally.
- Selective removal of CET implementation on platforms where it
is not supported (macOS).
- Integrated four more tests.
- Added Windows ARM64 architecture to tested platforms.
- Removed Solaris 10 support, fixed Solaris 11.
- libtls no longer links statically to libcrypto / libssl
unless --enable-libtls-only is specified at configure time.
- Improved Windows compatibility library, namely handling of
files vs sockets, correcting an exception when operating on a
closed socket.
- CMake builds no longer hardcode -O2 into the compiler flags,
instead using flags from the CMake build type instead.
- Set the CMake default build type to Release. This can be
overridden during configuration.
- Fixed broken ASM support with MinGW builds.
o New features
- Added support for truncated SHA-2 and for SHA-3.
- The BPSW primality test performs additional Miller-Rabin
rounds with random bases to reduce the likelihood of
composites passing.
- Allow testing of ciphers and digests using badly aligned
buffers in openssl speed using -unalign.
- Ed25519 certificates are now supported in openssl(1) ca and
req. Prepared Ed25519 support in libssl.
- Add branch target information (BTI) support to amd64 and
arm64 assembly.
o Compatibility changes
- Added a workaround for a poorly thought-out change in OpenSSL
3 that broke privilege separation support in libtls.
- Moved libtls from ECDSA_METHOD to EC_KEY_METHOD.
- Removed GF2m support: BIGNUM no longer supports binary
extension field arithmetic and all binary elliptic builtin
curves were removed.
- Removed dangerous, "fast" NIST prime and elliptic curve
implementations. In particular, EC_GFp_nist_method() is no
longer available.
- Removed most public symbols that were deprecated in OpenSSL
0.9.8.
- Removed the public X9.31 API (RSA_X931_PADDING is still
available).
- Removed Cipher Text Stealing mode.
- Removed ENGINE support, including ECDH_METHOD and
ECDSA_METHOD.
- Removed COMP, DSO, dynamic loading of conf modules and
support for custom ex_data and error stacks.
- Removed proxy certificate (RFC 3820) support.
- Removed SXNET and NETSCAPE_CERT_SEQUENCE support including
the openssl(1) nseq command.
- ENGINE support was removed and OPENSSL_NO_ENGINE is set. In
spite of this, some stub functions are provided to avoid
patching some applications that do not honor
OPENSSL_NO_ENGINE.
- The POLICY_TREE and its related structures and API were
removed.
- In X509_VERIFY_PARAM_inherit() copy hostflags independently
of the host list.
- Made CRYPTO_get_ex_new_index() not return 0 to allow
applications to use *_{get,set}_app_data() and
*_{get,set}_ex_data() alongside each other.
- X509_NAME_get_text_by_{NID,OBJ}() now only succeed if they
contain valid UTF-8 without embedded NUL.
- The explicitText user notice uses UTF8String instead of
VisibleString to reduce the risk of emitting certificates
with invalid DER-encoding.
- Initial fixes for RSA-PSS support to make the TLSv1.3 stack
more compliant with RFC 8446.
- Fixed EVP_CIPHER_CTX_iv_length() to return what was set with
EVP_CTRL_AEAD_SET_IVLEN or one of its aliases.
o Internal improvements
- Improved sieve of Eratosthenes script used for generating a
table of small primes.
- Removed incomplete and dangerous BN_RECURSION code.
- Imported RFC 5280 policy checking code from BoringSSL and
used it to replace the old exponential time code.
- Converted more of libcrypto to use CBB/CBS.
- Started cleaning up and rewriting SHA internals.
- Reduced the dependency of hash implementations on many layers
of macros. This results in significant speedups since modern
compilers are now less confused.
- Improved BIGNUM internals and performance.
- Significantly simplified the BN_BLINDING internals used in
RSA.
- Made BN_num_bits() independent of bn->top.
- Rewrote and simplified bn_sqr().
- Significantly improved Montgomery multiplication performance.
- Rewrote and improved BN_exp() and BN_copy().
- Changed ASN1_item_sign_ctx() and ASN1_item_verify() to work
with Ed25519 and fixed a few bugs in there.
- Lots of cleanup for DH, DSA, EC, RSA internals. Plugged
numerous memory leaks, fixed logic errors and
inconsistencies.
- Cleaned up and simplified various ECDH and ECDSA internals.
- Removed EC_GROUP precomp machinery.
- Fixed various issues with EVP_PKEY_CTX_{new,dup}().
- Rewrote OBJ_find_sigid_algs() and OBJ_find_sigid_by_algs().
- Improved X.509 certificate version checks.
- Ensure no X.509v3 extensions appear more than once in
certificates.
- Replaced ASN1_bn_print with a cleaner internal
implementation.
- Fix OPENSSL_cpuid_setup() invocations on arm/aarch64.
- Improved checks for commonName in libtls.
- Fixed error check for X509_get_ext_d2i() failure in libtls.
- Removed code guarded by #ifdef ZLIB.
- Plug a potential memory leak in ASN1_TIME_normalize().
- Fixed a use of uninitialized in i2r_IPAddrBlocks().
- Rewrote CMS_SignerInfo_{sign,verify}().
o Bug fixes
- Correctly handle negative input to various BIGNUM functions.
- Ensure ERR_load_ERR_strings() does not set errno
unexpectedly.
- Fix error checking of i2d_ECDSA_SIG() in ossl_ecdsa_sign().
- Fixed aliasing issue in BN_mod_inverse(). Disallowed aliasing
of result and modulus in various BN_mod_* functions.
- Fixed detection of extended operations (XOP) on AMD hardware.
- Ensure Montgomery exponentiation is used for the initial RSA
blinding.
- Policy is always checked in X509 validation. Critical policy
extensions are no longer silently ignored.
- Fixed error handling in tls_check_common_name().
- Add missing pointer invalidation in SSL_free().
- Fixed X509err() and X509V3err() and their internal versions.
- Ensure that OBJ_obj2txt() always returns a C string again.
- Made EVP_PKEY_set1_hkdf_key() fail on a NULL key.
- On socket errors in the poll loop, netcat could issue system
calls on invalidated file descriptors.
- Allow IP addresses to be specified in a URI.
- Fixed a copy-paste error in ASN1_TIME_compare() that could
lead to two UTCTimes or two GeneralizedTimes incorrectly
being compared as equal.
o Documentation improvements
- Improved documentation of BIO_ctrl(3),
BIO_set_info_callback(3), BIO_get_info_callback(3),
BIO_method_type(3), and BIO_method_name(3).
- Marked BIO_CB_return(), BIO_cb_pre(), and BIO_cb_post() as
intentionally undocumented.
- Made it very explicit that the verify callback should not be
used.
- Called out that the CRL lastUpdate is standardized as
thisUpdate.
- Documented the RFC 3779 API and its shortcomings.
o Testing and Proactive Security
- Significantly improved test coverage of BN_mod_sqrt() and
GCD.
- As always, new test coverage is added as bugs are fixed and
subsystems are cleaned up.
- OpenSSH 9.5 and OpenSSH 9.4
o Potentially incompatible changes
- ssh-keygen(1): generate Ed25519 keys by default. Ed25519
public keys are very convenient due to their small size.
Ed25519 keys are specified in RFC 8709 and OpenSSH has
supported them since version 6.5 (January 2014).
- sshd(8): the Subsystem directive now accurately preserves
quoting of subsystem commands and arguments. This may change
behaviour for exotic configurations, but the most common
subsystem configuration (sftp-server) is unlikely to be
affected.
- ssh-agent(1): PKCS#11 modules must now be specified by their
full paths. Previously dlopen(3) could search for them in
system library directories.
o New features
- ssh(1): add keystroke timing obfuscation to the client. This
attempts to hide inter-keystroke timings by sending
interactive traffic at fixed intervals (default: every 20ms)
when there is only a small amount of data being sent. It also
sends fake "chaff" keystrokes for a random interval after the
last real keystroke. These are controlled by a new ssh_config
ObscureKeystrokeTiming keyword.
- ssh(1), sshd(8): Introduce a transport-level ping facility.
This adds a pair of SSH transport protocol messages
SSH2_MSG_PING/PONG to implement a ping capability. These
messages use numbers in the "local extensions" number space
and are advertised using a "ping@openssh.com" ext-info
message with a string version number of "0".
- sshd(8): allow override of Subsystem directives in sshd Match
blocks.
- ssh(1): allow forwarding Unix Domain sockets via ssh -W.
- ssh(1): add support for configuration tags to ssh(1). This
adds a ssh_config(5) "Tag" directive and corresponding "Match
tag" predicate that may be used to select blocks of
configuration similar to the pf.conf(5) keywords of the same
name.
- ssh(1): add a "match localnetwork" predicate. This allows
matching on the addresses of available network interfaces and
may be used to vary the effective client configuration based
on network location.
- ssh(1), sshd(8), ssh-keygen(1): infrastructure support for
KRL extensions. This defines wire formats for optional KRL
extensions and implements parsing of the new submessages. No
actual extensions are supported at this point.
- sshd(8): AuthorizedPrincipalsCommand and
AuthorizedKeysCommand now accept two additional %-expansion
sequences: %D which expands to the routing domain of the
connected session and %C which expands to the addresses and
port numbers for the source and destination of the
connection.
- ssh-keygen(1): increase the default work factor (rounds) for
the bcrypt KDF used to derive symmetric encryption keys for
passphrase protected key files by 50%.
o Bugfixes
- scp(1): fix scp in SFTP mode recursive upload and download of
directories that contain symlinks to other directories. In
scp mode, the links would be followed, but in SFTP mode they
were not.
- ssh-keygen(1): handle cr+lf (instead of just cr) line endings
in sshsig signature files.
- ssh(1): interactive mode for ControlPersist sessions if they
originally requested a tty.
- sshd(8): make PerSourceMaxStartups first-match-wins
- sshd(8): limit artificial login delay to a reasonable maximum
(5s) and don't delay at all for the "none" authentication
mechanism.
- sshd(8): Log errors in kex_exchange_identification() with
level verbose instead of error to reduce preauth log spam.
All of those get logged with a more generic error message by
sshpkt_fatal().
- sshd(8): correct math for ClientAliveInterval that caused the
probes to be sent less frequently than configured.
- ssh-agent(1): improve isolation between loaded PKCS#11
modules by running separate ssh-pkcs11-helpers for each
loaded provider.
- ssh(1): make -f (fork after authentication) work correctly
with multiplexed connections, including ControlPersist.
- ssh(1): make ConnectTimeout apply to multiplexing sockets and
not just to network connections.
- ssh-agent(1), ssh(1): improve defences against invalid
PKCS#11 modules being loaded by checking that the requested
module contains the required symbol before loading it.
- sshd(8): fix AuthorizedPrincipalsCommand when
AuthorizedKeysCommand appears before it in sshd_config. Since
OpenSSH 8.7 the AuthorizedPrincipalsCommand directive was
incorrectly ignored in this situation.
- sshd(8), ssh(1), ssh-keygen(1): remove vestigial support for
KRL signatures When the KRL format was originally defined, it
included support for signing of KRL objects. However, the
code to sign KRLs and verify KRL signatures was never
completed in OpenSSH. This release removes the
partially-implemented code to verify KRLs. All OpenSSH tools
now ignore KRL_SECTION_SIGNATURE sections in KRL files.
- All: fix a number of memory leaks and unreachable/harmless
integer overflows.
- ssh-agent(1), ssh(1): don't truncate strings logged from
PKCS#11 modules
- sshd(8), ssh(1): better validate CASignatureAlgorithms in
ssh_config and sshd_config. Previously this directive would
accept certificate algorithm names, but these were unusable
in practice as OpenSSH does not support CA chains.
- ssh(1): make ssh -Q CASignatureAlgorithms only list signature
algorithms that are valid for CA signing. Previous behaviour
was to list all signing algorithms, including certificate
algorithms.
- ssh-keyscan(1): gracefully handle systems where rlimits or
the maximum number of open files is larger than INT_MAX
- ssh-keygen(1): fix "no comment" not showing on when running
ssh-keygen -l on multiple keys where one has a comment and
other following keys do not.
- scp(1), sftp(1): adjust ftruncate() logic to handle servers
that reorder requests. Previously, if the server reordered
requests then the resultant file would be erroneously
truncated.
- ssh(1): don't incorrectly disable hostname canonicalization
when CanonicalizeHostname=yes and ProxyJump was explicitly
set to "none".
- scp(1): when copying local to remote, check that the source
file exists before opening an SFTP connection to the server.

------------------------------------------------------------------------
- SECURITY AND ERRATA --------------------------------------------------
We provide patches for known security threats and other important
issues discovered after each release. Our continued research into
security means we will find new security problems -- and we always
provide patches as soon as possible. Therefore, we advise regular
visits to
https://www.OpenBSD.org/security.html
and
https://www.OpenBSD.org/errata.html
------------------------------------------------------------------------
- MAILING LISTS AND FAQ ------------------------------------------------
Mailing lists are an important means of communication among users and
developers of OpenBSD. For information on OpenBSD mailing lists, please
see:
https://www.OpenBSD.org/mail.html
You are also encouraged to read the Frequently Asked Questions (FAQ) at:
https://www.OpenBSD.org/faq/
------------------------------------------------------------------------
- DONATIONS ------------------------------------------------------------
The OpenBSD Project is a volunteer-driven software group funded by
donations. Besides OpenBSD itself, we also develop important software
like OpenSSH, LibreSSL, OpenNTPD, OpenSMTPD, the ubiquitous pf packet
filter, the quality work of our ports development process, and many
others. This ecosystem is all handled under the same funding umbrella.
We hope our quality software will result in contributions that maintain
our build/development infrastructure, pay our electrical/internet costs,
and allow us to continue operating very productive developer hackathon
events.
All of our developers strongly urge you to donate and support our future
efforts. Donations to the project are highly appreciated, and are
described in more detail at:
https://www.OpenBSD.org/donations.html
------------------------------------------------------------------------
- OPENBSD FOUNDATION ---------------------------------------------------
For those unable to make their contributions as straightforward gifts,
the OpenBSD Foundation (https://www.openbsdfoundation.org) is a Canadian
not-for-profit corporation that can accept larger contributions and
issue receipts. In some situations, their receipt may qualify as a
business expense write-off, so this is certainly a consideration for
some organizations or businesses.
There may also be exposure benefits since the Foundation may be
interested in participating in press releases. In turn, the Foundation
then uses these contributions to assist OpenBSD's infrastructure needs.
Contact the foundation directors at directors@openbsdfoundation.org for
more information.
------------------------------------------------------------------------
- HTTPS INSTALLS -------------------------------------------------------
OpenBSD can be easily installed via HTTPS downloads. Typically you need
a single small piece of boot media (e.g., a USB flash drive) and then
the rest of the files can be installed from a number of locations,
including directly off the Internet. Follow this simple set of
instructions to ensure that you find all of the documentation you will
need while performing an install via HTTPS.
1) Read either of the following two files for a list of HTTPS mirrors
which provide OpenBSD, then choose one near you:
https://www.OpenBSD.org/ftp.html
https://ftp.openbsd.org/pub/OpenBSD/ftplist
As of October 16, 2023, the following HTTPS mirror sites have the
7.4 release:
https://cdn.openbsd.org/pub/OpenBSD/7.4/ Global
https://ftp.eu.openbsd.org/pub/OpenBSD/7.4/ Stockholm, Sweden
https://ftp.hostserver.de/pub/OpenBSD/7.4/ Frankfurt, Germany
https://ftp.bytemine.net/pub/OpenBSD/7.4/ Oldenburg, Germany
https://ftp.fr.openbsd.org/pub/OpenBSD/7.4/ Paris, France
https://mirror.aarnet.edu.au/pub/OpenBSD/7.4/ Brisbane, Australia
https://ftp.usa.openbsd.org/pub/OpenBSD/7.4/ CO, USA
https://ftp5.usa.openbsd.org/pub/OpenBSD/7.4/ CA, USA
https://mirror.esc7.net/pub/OpenBSD/7.4/ TX, USA
https://openbsd.cs.toronto.edu/pub/OpenBSD/7.4/ Toronto, Canada
https://cloudflare.cdn.openbsd.org/pub/OpenBSD/7.4/ Global
https://fastly.cdn.openbsd.org/pub/OpenBSD/7.4/ Global
The release is also available at the master site:
https://ftp.openbsd.org/pub/OpenBSD/7.4/ Alberta, Canada
However it is strongly suggested you use a mirror.
Other mirror sites may take a day or two to update.
2) Connect to that HTTPS mirror site and go into the directory
pub/OpenBSD/7.4/ which contains these files and directories.
This is a list of what you will see:
ANNOUNCEMENT armv7/ octeon/ root.mail
README hppa/ openbsd-74-base.pub sparc64/
SHA256 i386/ packages/ src.tar.gz
SHA256.sig landisk/ packages-stable/ sys.tar.gz
alpha/ loongson/ ports.tar.gz xenocara.tar.gz
amd64/ luna88k/ powerpc64/
arm64/ macppc/ riscv64/
It is quite likely that you will want at LEAST the following
files which apply to all the architectures OpenBSD supports.
README - generic README
root.mail - a copy of root's mail at initial login.
(This is really worthwhile reading).
3) Read the README file. It is short, and a quick read will make
sure you understand what else you need to fetch.
4) Next, go into the directory that applies to your architecture,
for example, amd64. This is a list of what you will see:
BOOTIA32.EFI* bsd* floppy74.img pxeboot*
BOOTX64.EFI* bsd.mp* game74.tgz xbase74.tgz
BUILDINFO bsd.rd* index.txt xfont74.tgz
INSTALL.amd64 cd74.iso install74.img xserv74.tgz
SHA256 cdboot* install74.iso xshare74.tgz
SHA256.sig cdbr* man74.tgz
base74.tgz comp74.tgz miniroot74.img
If you are new to OpenBSD, fetch _at least_ the file INSTALL.amd64
and install74.iso. The install74.iso file (roughly 633MB in size)
is a one-step ISO-format install CD image which contains the various
*.tgz files so you do not need to fetch them separately.
If you prefer to use a USB flash drive, fetch install74.img and
follow the instructions in INSTALL.amd64.
5) If you are an expert, follow the instructions in the file called
README; otherwise, use the more complete instructions in the
file called INSTALL.amd64. INSTALL.amd64 may tell you that you
need to fetch other files.
6) Just in case, take a peek at:
https://www.OpenBSD.org/errata.html
This is the page where we talk about the mistakes we made while
creating the 7.4 release, or the significant bugs we fixed
post-release which we think our users should have fixes for.
Patches and workarounds are clearly described there.

- X.ORG FOR MOST ARCHITECTURES -----------------------------------------
X.Org has been integrated more closely into the system. This release
contains X.Org 7.7. Most of our architectures ship with X.Org, including
amd64, sparc64 and macppc. During installation, you can install X.Org
quite easily using xenodm(1), our simplified X11 display manager forked
from xdm(1).
------------------------------------------------------------------------
- PACKAGES AND PORTS ---------------------------------------------------
Many third party software applications have been ported to OpenBSD and
can be installed as pre-compiled binary packages on the various OpenBSD
architectures. Please see https://www.openbsd.org/faq/faq15.html for
more information on working with packages and ports.
Note: a few popular ports, e.g., NSD, Unbound, and several X
applications, come standard with OpenBSD and do not need to be installed
separately.
------------------------------------------------------------------------
- SYSTEM SOURCE CODE ---------------------------------------------------
The source code for all four subsystems can be found in the
pub/OpenBSD/7.4/ directory:
xenocara.tar.gz ports.tar.gz src.tar.gz sys.tar.gz
The README (https://ftp.OpenBSD.org/pub/OpenBSD/7.4/README) file
explains how to deal with these source files.
