<h3><font color="#0000e0">Changes made between OpenBSD 6.5 and -current</font></h3>
<p>

<ul>
<!-- 2019/04/21 -->
<li>Set <a href="https://man.openbsd.org/vlan">vlan(4)</a> to use if_vinput instead of if_input, bypassing ifiqs and improving vlan input speeds.
<li>Added if_vinput so pseudo (ethernet) interfaces can bypass ifiqs, running interface input handlers directly rather than queuing the packets for a nettq to run and improving performance.
<li>Disabled <a href="https://man.openbsd.org/OpenBSD-6.4/mobileip">mobileip(4)</a>.
<li>Added support for rxprio to <a href="https://man.openbsd.org/gre">gre(4)</a>.
<li>Implemented the <a href="https://man.openbsd.org/roff">roff(7)</a> .break request, preventing infinite loops.
<li>Built <a href="https://man.openbsd.org/clang">clang(1)</a> on powerpc.
<li>Used IPL_TTY to prevent 'locking against myself' panics for drm/i915.
<li>Fixed crashes seen with the 'intel' X driver with the new <a href="https://man.openbsd.org/inteldrm">inteldrm(4)</a> kernel driver by fixing rbtree_postorder_for_each_entry_safe() implementation.
<li>Fixed unreliable 'ifconfig mode' with some wireless drivers by interpreting ENETRESET from ifm_change() as success in ifmedia_ioctl().
<!-- 2019/04/20 -->
<li>Added stdio <a href="https://man.openbsd.org/pledge">pledge(2)</a> to <a href="https://man.openbsd.org/nl">nl(1)</a> after opening a file but before doing operations.
<li>Completed conversion of <a href="https://man.openbsd.org/rdsetroot">rdsetroot(8)</a> to -lelf on alpha.
<li>Adjusted dma-range bufcache to 80% from 20%, to learn the downsides of this change based on user reports.
<li>Avoided an underflow in the rip6 delivered counter in <a href="https://man.openbsd.org/netstat">netstat(1)</a>.
<li>Fixed <a href="https://man.openbsd.org/netstat">netstat(1)</a> statistics so 'netstat -s -f inet6 -p rip6' correctly copies out rip6counters, not ip6counters.
<!-- 2019/04/19 -->
<li>Adapted radeon_detach_kms() to struct drm_device being split from drm softc. Avoids uvm_fault() when firmware is missing and <a href="https://man.openbsd.org/radeondrm">radeondrm(4)</a> is forcibly detached.
<li>Added a subsystem lock for vfs_lockf.c, allowing calling lf_advlock() and lf_purgelocks() without the kernel lock.
<li>Implemented factored-out txprio and rxprio checks.
<li>Implemented rxprio in <a href="https://man.openbsd.org/mpw">mpw(4)</a>, <a href="https://man.openbsd.org/mpe">mpe(4)</a> and <a href="https://man.openbsd.org/mpip">mpip(4)</a>. Added rxprio support to <a href="https://man.openbsd.org/etherip">etherip(4)</a> and <a href="https://man.openbsd.org/bpe">bpe(4)</a>.
<!-- 2019/04/18 -->
<li>Added support to <a href="https://man.openbsd.org/ifconfig">ifconfig(8)</a> for getting and setting rxprio, finishing support for RFC 2983. Implemented configuring rxprio in <a href="https://man.openbsd.org/vlan">vlan(4)</a>.
<li>Modified <a href="https://man.openbsd.org/pfctl">pfctl(8)</a> to always check for namespace collisions on table commands.
<li>Fixed <a href="https://man.openbsd.org/pfctl">pfctl(8)</a> table definition parsing as unprivileged user, printing a brief notice if -v was given to help find duplicate definitions by hand.
<li>Modified <a href="https://man.openbsd.org/sshd">sshd(8)</a> -T to assume any attribute not provided by -C does not match, allowing it to work when <a href="https://man.openbsd.org/sshd_config">sshd_config(5)</a> contains a Match directive with or without -C.
<!-- 2019/04/17 -->
<li>Released OpenSSH 8.0.
<li>Switched powerpc to big PIC to allow <a href="https://man.openbsd.org/clang">clang(1)</a> to build libc++abi and libc++.
<!-- 2019/04/16 -->
<li>Used txprio to control the use of exp as a priority field for <a href="https://man.openbsd.org/mpw">mpw(4)</a>, <a href="https://man.openbsd.org/mpip">mpip(4)</a> and <a href="https://man.openbsd.org/mpe">mpe(4)</a>. Intermediate LSPs can use the exp field to manage prioritization of encapsulated traffic.
<li>Prevented attaching drivers to devices for which a driver was attached early with simplebus on armv7 and arm64.
<li>Adjusted <a href="https://man.openbsd.org/myx">myx(4)</a> i2c reads to read only one byte at a time, increasing reliability.
<li>Fixed sff page reads for <a href="https://man.openbsd.org/myx">myx(4)</a> devices on little endian architectures.
<li>Rewrote <a href="https://man.openbsd.org/rdsetroot">rdsetroot(8)</a> using <a href="https://man.openbsd.org/libelf">libelf(3)</a>.
<!-- 2019/04/15 -->
<li>Imported xf86-video-amdgpu 19.0.1 for amd64 and i386.
<li>Implemented tx mitigation by calling the hardware transmit routine per several packets rather than for individual packets. Defers calls to the transmit routine to a network taskq, or until a backlog of packets has built up.
<li>Introduced 'pfctl -FR' to reset <a href="https://man.openbsd.org/pfctl">pfctl(8)</a> settings to defaults.
<li>Removed old -vlan and -vlandev code from <a href="https://man.openbsd.org/ifconfig">ifconfig(8)</a>, using these instead as aliases for -vnetid and -parent.
<!-- 2019/04/14 -->
<li>Added basic support to <a href="https://man.openbsd.org/ifconfig">ifconfig(8)</a> to display xfp and qsfp+ information.
<li>Implemented SIOCGIFSFFPAGE to allow <a href="https://man.openbsd.org/ifconfig">ifconfig(8)</a> to get transceiver information from <a href="https://man.openbsd.org/myx">myx(4)</a> devices.
<li>Applied <a href="https://man.openbsd.org/strvis">strvis(3)</a> to strings from USB devices in <a href="https://man.openbsd.org/usbdevs">usbdevs(8)</a>.
<li>Removed the potential for double-frees in copied cipher data by zeroing and freeing following EVP_CIPHER_CTX_copy() in <a href="https://man.openbsd.org/evp">evp(3)</a>. Used <a href="https://man.openbsd.org/calloc">calloc(3)</a> when allocating cipher_data to avoid use of uninitialized memory.
<li>Updated shared drm code, <a href="https://man.openbsd.org/inteldrm">inteldrm(4)</a> and <a href="https://man.openbsd.org/radeondrm">radeondrm(4)</a> to linux 4.19.34. This adds support for Intel Broxton/Apollo Lake, Amber Lake, Gemini Lake, Coffee Lake, Whiskey Lake, Cannon Lake and Ice Lake hardware.
<li>Stopped using <a href="https://man.openbsd.org/splnet">splnet(9)</a> when running the network stack now that it is using the NET_LOCK for protection, reducing latency spikes.
<!-- 2019/04/13 -->
<li>Increased information displayed for -v and -vv options for <a href="https://man.openbsd.org/tcpdump">tcpdump(8)</a> during md5 authentication.
<li>Added missing compatibles for newer Linux kernel bindings to <a href="https://man.openbsd.org/mvpinctrl">mvpinctrl(4)</a>.
<li>Fixed a leak in SSL_dup_CA_list() in <a href="https://man.openbsd.org/man3/ssl.3">ssl(3)</a>.
</ul>
