Line 205

Line 256

href="https://man.openbsd.org/sndiod.8">sndiod(8)</a> and for <a

href="https://man.openbsd.org/aucat.1">aucat(1)</a>, removing most of

the aliasing noise during resampling.

<li>Disabled <a href="https://man.openbsd.org/sndiod.8">sndiod(8)</a>

autovolume by default and set the default volume to 127. Setting "-w

on" will replicate the previous behavior of automatically decreasing

playback volume when new programs start playing.

<li>Allowed mixing of alternative devices (-F) with different

capabilities in <a

href="https://man.openbsd.org/sndiod.8">sndiod(8)</a> by treating any

device as full-duplex.

href="https://man.openbsd.org/fdisk.8">fdisk(8)</a> safer by

defaulting offset to the beginning of the largest free space and

preventing the creation of overlapping partitions.

<li>Fixed a crash that could occur in <a

href="https://man.openbsd.org/sndiod.8">sndiod(8)</a> when a usb

device is unplugged.

Line 292

Line 384

<li>Added Gemini Lake I2C id to <a

href="https://man.openbsd.org/dwiic.4">dwiic(4)</a>, making the

touchpad work on the Teclast F7 Plus laptop.

<li>Introduced <a href="https://man.openbsd.org/ujoy.4">ujoy(4)</a>, a

restricted subset of <a

href="https://man.openbsd.org/uhid.4">uhid(4)</a> for game controllers

which uses /dev/ujoy/* device nodes.

<li>Set up <a href="https://man.openbsd.org/ims.4">ims(4)</a> devices

in X11 to behave like touchpads.

<li>Stopped relying on USB devices to correctly present their

indices, instead searching for the correct interfaces. This fixes E+

Corp. DAC Audio devices.

<li>Introduced <a

href="https://man.openbsd.org/uhidpp.4">uhidpp(4)</a>, a driver for

Logitech HID++ devices.

<li>Optimized arm64 <a

href="https://man.openbsd.org/copyin.9">copyin(9)</a>, <a

Line 322

Line 428

controller found on Amlogic G12A/G12B/SM1 SoCs.

<li>Implemented intx support in <a

href="https://man.openbsd.org/mvkpcie.4">mvkpcie(4)</a>.

<li>Added <a href="https://man.openbsd.org/cryptox.4">cryptox(4)</a>,

a driver for armv8 cryptographic extensions.

<li>Added support for PCIe on the NanoPi R4S to <a

href="https://man.openbsd.org/rkpcie.4">rkpcie(4)</a>.

</ul>

Line 352

Line 462

href="https://man.openbsd.org/rge.4">rge(4)</a>.

<li>Enabled IPv4 and TCP/UDP checksum offload on transmission in <a

href="https://man.openbsd.org/ogx.4">ogx(4)</a>.

<li>Raised the maximum number of queues/interrupts from 1 to 16 on <a

href="https://man.openbsd.org/mcx.4">mcx(4)</a> devices.

</ul>

Line 370

Line 483

href="https://man.openbsd.org/bwfm.4">bwfm(4)</a> on the BCM43602 that

was triggering "unexpected pairwise key update" errors.

<li>Enabled <a href="https://man.openbsd.org/athn.4">athn(4)</a> for arm64.

<li>Added support for version 7 of the <a

href="https://man.openbsd.org/bwfm.4">bwfm(4)</a> PCIe interface.

</ul>

to renew pltime/vltime of privacy addresse per RFC 4941.

<li>Fixed <a href="https://man.openbsd.org/wg.4">wg(4)</a> on macppc

by keeping track of allowed ips pointer correctly.

<li>Use the toeplitz hash algorithm to a flowid for tcp packets,

which in turn is used to choose the tx ring on network cards with

multiple rings.

<li>Fixed <a href="https://man.openbsd.org/wg.4">wg(4)</a> ioctl to

handle multiple wgpeers.

<li>Removed the direct ACK on every other data segment. After

receiving a data segment, we were sending out two ACKs, the first one

in tcp_input() direct after receiving and the second ACK after the

userland or the sosplice task read some data out of the socket buffer.

This change removes the ACK in tcp_input(), saving processing time and

improving network performance.

<li>Removed the maxburst feature from tcp_output().

<li>Added a MONITOR feature to interfaces. Packets received on these

interfaces do not enter the network stack for further processing. This

can be used to watch traffic, for example with <a

href="https://man.openbsd.org/bpf.4">bpf(4)</a> without risk of the packets

interfering with the system.

<li>Added etherbridge, the internals of a reusable learning bridge

interface providing common code reusable for other drivers needing a

mac learning bridge.

<li>Introduced <a href="https://man.openbsd.org/veb.4">veb(4)</a>, a

Virtual Ethernet Bridge driver.

<li>Added support for adding and deleting mac addr entries on <a

href="https://man.openbsd.org/nvgre.4">nvgre(4)</a>.

<li>Added support for adding and deleting address table entries to <a

href="https://man.openbsd.org/bpe.4">bpe(4)</a>, <a

href="https://man.openbsd.org/veb.4">veb(4)</a> and etherbridge.

</ul>

<li>Installer improvements:

Line 443

Line 588

"show sets" to display information about the roa-set, as-sets and

prefix-sets loaded into <a

href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>.

<li>Introduced the <a

href="https://man.openbsd.org/bgpd.conf.5">bgpd.conf(5)</a> per

neighbor and global config option "reject as-set yes/no" to allow

rejection of received UPDATES with AS_SET segments. These rejected

prefixes can be viewed with <a

href="https://man.openbsd.org/bgpctl.8">bgpctl(8)</a> "show rib in

error".

<li>Properly implemented "rde med compare strict" in <a

href="https://man.openbsd.org/bgpd.8">bgpd(8)</a> and ensured that the

order of prefixes is always correct.

<li>Added RTR support to <a href="https://man.openbsd.org/bgpd.8">OpenBGPD</a>.

<li>Added <a href="https://man.openbsd.org/bgpctl.8">bgpctl(8)</a>

"show rtr" to display basic information about RTR sessions.

<li>Introduced <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>

<code>rde evaluate all</code> to work around path hiding in IXP

route-server environments.

<li>Allowed use of <a

href="https://man.openbsd.org/ospfd.8">ospfd(8)</a> on interfaces that

share the same IP.

Line 514

Line 677

IPv6 support.

<li>Created a path MTU host route for <a

href="https://man.openbsd.org/ipsec.4">IPsec(4)</a> over IPv6.

<li>Added support for INVALID_KE_PAYLOAD in <a

href="https://man.openbsd.org/iked.8">iked(8)</a> CREATE_CHILD_SA

exchange.

<li>Added support for RSA-PSS PKCS1 signatures to <a

href="https://man.openbsd.org/iked.8">iked(8)</a>.

<li>Fixed path MTU discovery for ESP tunnels in IPv6.

<li>Upgraded to OpenSSL 1.1 compatible crypto API in <a

href="https://man.openbsd.org/iked.8">iked(8)</a>.

<li>Added an optional "group none" transform for child SAs in <a

href="https://man.openbsd.org/iked.8">iked(8)</a> to ensure the

ability to negotiate optional PFS.

<li>Added <a href="https://man.openbsd.org/iked.8">iked(8)</a>

dynamic address configuration for roadwarrior clients, with a new

"iface" config option which can be used to specify an interface for

the virtual addresses received from the peer.

<li>Fixed <a href="https://man.openbsd.org/ldapd.8">ldapd(8)</a> cert

and key path inference for absolute paths.

<li>Applied <a href="https://man.openbsd.org/unveil.2">unveil(2)</a>

to <a href="https://man.openbsd.org/ldapd.8">ldapd(8)</a>.

Line 706

href="https://man.openbsd.org/pfctl.8">pfctl(8)</a> and <a

href="https://man.openbsd.org/pf.4">pf(4)</a> to accept any valid

routing domain, even if it does not yet exist.

<li>Made <a href="https://man.openbsd.org/pfctl.8">pfctl(8)</a>

detect and reject bogus ranges before loading the ruleset to prevent a

panic.

<li>Changed route-to in <a

href="https://man.openbsd.org/pf.conf.5">pf.conf(5)</a> to send

packets to IPs instead of interfaces.

<li>Changed pf_route so <a

href="https://man.openbsd.org/pf.4">pf(4)</a> only runs when packets

enter and leave the stack. Running the same packet through pf multiple

times creates confusion for the state table. By default, pf states are

floating, meaning that packets are matched to states regardless of

which interface they're going over. This diff avoids multiple pf(4)

traversals of one packet causing confusion in the state table.

<li>Prevented the kernel from being stuck in an endless recursion

during TCP path MTU discovery when <a

href="https://man.openbsd.org/pf.4">pf(4)</a> changes the routing

table when sending packets.

<li>When cutting off the head of an overlapping fragment during <a

href="https://man.openbsd.org/pf.4">pf(4)</a> reassembly, reinserted

the fragment into the lookup table with the correct index.

<li>Implemented RFC 8914 Extended DNS Errors for <a

href="https://man.openbsd.org/dig.1">dig(1)</a>.

Line 557

Line 752

drain the raw socket of packets received before we were fully setup to

avoid reporting ICMP responses intended for other instances of ping(8)

running in parallel.

<li>Added <a href="https://man.openbsd.org/ping.8">ping(8)</a> -g

option to provide a visual display of packets received and lost.

<li>Changed <a href="https://man.openbsd.org/slaacd.8">slaacd(8)</a>

Duplicate Address Detection (DAD) to only generate a new address if we

Line 569

Line 766

<li>Implemented <a

href="https://man.openbsd.org/unwind.8">unwind(8)</a> listening on

TCP.

<li>Implemented DNS64 synthesis in <a

href="https://man.openbsd.org/unwind.8">unwind(8)</a>.

<li>Disabled logging to <a

href="https://man.openbsd.org/syslog.3">syslog(3)</a> for libunbound

with <a href="https://man.openbsd.org/unwind.8">unwind(8)</a>. Does

not prevent logging to stderr with "unwind -d".

<li>Removed the -L option from <a

href="https://man.openbsd.org/dhclient.8">dhclient(8)</a>.

<li>Added a simple --timeout implementation to <a

Line 585

Line 789

and IP protocol.

<li>Handle permanent redirects (RFC 7538) in <a

href="https://man.openbsd.org/ftp.1">ftp(1)</a> fetch.

<li>Introduced <a href="https://man.openbsd.org/ftp.1">ftp(1)</a>

support for sending the If-Modified-Since header while fetching over

http or https. Switched to using the timestamps from the remote

server's Last-Modified header if available when saving local files and

introduced the ftp "-u" flag to disable this behavior.

<li>Added requests for a new certificate without requiring -F when <a

href="https://man.openbsd.org/acme-client.1">acme-client(1)</a>

detects an added or removed SAN in the config file not reflected in

Line 593

href="https://man.openbsd.org/pflog.4">pflog(4)</a> for rdr-to, nat-to

and af-to rules.

<li>Removed the <a

href="https://man.openbsd.org/snmpd.8">snmpd(8)</a> traphandler

process.

<li>When calling <a

href="https://man.openbsd.org/getaddrinfo.3">getaddrinfo(3)</a> with

AI_ADDRCONFIG, consider the routing domain when checking for available

address families. This ensures that name resolution is only performed

for the address families available in the rdomain.

<li>Implemented the <a href="https://man.openbsd.org/nc.1">nc(1)</a>

-D socket debug option in <a

href="https://man.openbsd.org/tcpbench.1">tcpbench(1)</a>, allowing

analysis of TCP connections.

Line 698

Line 922

href="https://man.openbsd.org/ssh_config.5">ssh_config(5)</a>.

<li>Added PerSourceMaxStartups and PerSourceNetBlockSize options to

<a href="https://man.openbsd.org/sshd.8">sshd(8)</a>.

<li>Renamed the PubkeyAcceptedKeyTypes keyword to

PubkeyAcceptedAlgorithms in <a

href="https://man.openbsd.org/ssh_config.5">ssh_config(5)</a> and <a

href="https://man.openbsd.org/sshd_config.5">sshd_config(5)</a>.

<li>Renamed the HostbasedKeyTypes keyword in <a
