Line 103

<li>Take more functions in the network and routing code out

of kernel lock.

<li>Implement dt(4) utrace support on amd64 and i386.

<li>Implement battery management sysctl(8) hw.battery.chargemode, hw.battery.chargestop and

</ul>

<li>SMP Improvements

Line 317

Line 318

<li>Do not fail in

<a href="https://man.openbsd.org/ober_scanf_elements.3"

>ober_scanf_elements(3)</a> when encountering empty sequences.

<li>In clang(1), turn on pointer-authentication on arm64 by default.

</ul>

<li>Improved hardware support and driver bugfixes, including:

Line 369

Line 371

<li>In the SCSI tape driver st(4) add support for I/O statistics so

that tape speeds can be observed with iostat(8).

<li>Add support for the RTL8153D chipset in ure(4).

<li>Add support for the Peripheral Authentication Service SMC

interface in qcscm(4).

<li>Add qcmtx(4), a driver for the hardware spinlock on Qualcomm

SoCs that is used to synchronize access to the shared memory table.

<li>Add qcsmptp(4), a driver to share 32-bit values between (co-)processors.

<li>Implement battery charge control in acpithinkpad(4).

<li>Add qcaoss(4), a driver for the Always On Subsystem found on Qualcomm SoCs.

<li>Implement battery charge control for the Apple System Management Controller aplsmc(4).

</ul>

<li>New or improved network hardware support:

Line 402

Line 412

<li>Improve how Quectel LTE&5G devices attach to

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

<li>Add initial support for Atlantic 2 hardware in aq(4).

<li>Use TSO offloading in ix(4). Enable forwarding of ix(4) LRO Pakets via TSO.

</ul>

<li>IEEE 802.11 wireless stack improvements and bugfixes:

Line 512

Line 523

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.

<li>Set TSO flag on vlan(4) interfaces.

<li>In pf(4), relax the implementation of the "pass all" rule so all

forms of neighbor advertisements are allowed in either direction.

<li>Inbound portion of RFC9131. Routers can create new neighbor cache entries

when receiving a valid Neighbor Advertisement.

<li>Implement RFC9131 and create new neighbor cache entries

when receiving a valid Neighbor Advertisement.

<li>Implement TCP send offloading in software. Implement the TCP/IP

layer for hardware TCP segmentation offload. If the driver of a

network interface claims to support TSO, do not chop the packet in

software, but pass it down to the interface layer. Add sysctl(8) net.inet.tcp.tso.

<li>Do not calculate IP, TCP, UDP checksums on loopback (lo(4)) interfaces.

<li>Fix a bug in pf(4), where nat-to clould fail to insert a state

due to conflict on chosen source port number.

<li>Implement TCP send offloading, for now in software only. This is

meant as a fallback if network hardware does not support TSO.

<li>Fix a bug in pf(4), where nat-to could fail to insert a state

due to conflict on chosen source port number.

</ul>

<li>Routing daemons and other userland network improvements:

Line 664

Line 678

timers for prefix preferred and valid lifetimes to use the values from

RFC 9096.

<li>In pfctl(8), speed up how pf(4) rules are retrieved from the kernel.

<li>In slaacd(8), remove artificial limit of 2 hours on a PIO lifetime.

<li>In slaacd(8), remove artifical limit of 2 hours on a PIO lifetime.

<li>In ypldap(8), make ypldap more resilient when some servers are

misbehaving: keep trying LDAP servers until we get full results from

one, rather than just until one accepts the TCP connection.

<li>Add support for wireguard (wg(4)) peer descriptions, which can

now be added with ifconfig(8).

<li>Make the tlsv1.0 and tlsv1.1 options in relayd(8) do nothing, as

one should use tlsv1.2 instead.

</ul>

<li><a href="https://man.openbsd.org/tmux.1">tmux(1)</a> improvements and bug fixes:
