catch up with box drawing characters which have

been standardized in unicode after the original wscons code was

written and chose placeholder values.

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

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

of kernel lock.

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

</ul>

<li>SMP Improvements

Line 115

<li>Unlock more parts of

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

code in the network stack.

<li>Remove the kernel lock from IPv6 neighbor discovery.

</ul>

<li>Direct Rendering Manager and graphics drivers

Line 211

Line 212

<li>Accept the <a href="https://man.openbsd.org/ucom.4">ucom(4)</a> fixed

name format as a valid format for the

<a href="https://man.openbsd.org/cu.1">cu(1)</a> -l option.

<li>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.

</ul>

<li>Various bugfixes and tweaks in userland:

Line 347

Line 355

<li>Enabled the caps lock LED on modern Apple laptop keyboards.

<li>Add support for Rockchip "cryptov2-rng" random number generator in

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

<li>Add qcrng(4), a driver for the Qualcomm rng device found on the Thinkpad X13s

<li>Fixed cpuperf on the Apple M2 Pro/Max.

<li>Add support for the PCIe controller found on Apple M2 Pro/Max SoCs.

<li>Add support for enabling both the USB2 and USB3 PHYs in

Line 357

Line 366

<li>Add dwmshc(4) to support Designware Mobile Storage Host Controllers

found on rk356x and rk3588 SoCs.

<li>Add iosf(4), a driver for the Intel OnChip System Fabric.

<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).

</ul>

<li>New or improved network hardware support:

Line 473

Line 485

include file names.

<li>On amd64, enable Indirect Branch Tracking (IBT) for the kernel.

<li>Enable branch target control flow enforcement on arm64.

<li>In clang on amd64, emit IBT endbr64 instructions by default (meaning,

-fcf-protection=branch is the default).

</ul>

<li>Changes in the network stack:

Line 498

Line 512

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, 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 clould fail to insert a state

due to conflict on chosen source port number.

</ul>

<li>Routing daemons and other userland network improvements:

Line 639

Line 665

<li>Improved error handling in the <a

href="https://man.openbsd.org/asr_run.3">asr</a> resolver.

<li>In unwind(8), handle SERVFAIL results on name resolution better.

<li>In the router advertisement daemon rad(8), update the default

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 artifical limit of 2 hours on a PIO lifetime.

</ul>

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

Line 650

Line 682

<li>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.

<li>Add options to change the confirm key and default behaviour of

confirm-before.

</ul>

<li>LibreSSL version 3.8.2
