<li>Filesystem midlayer improvements:

<ul>

<li>...

<li>fix internal locking in (still experimental!) NFTS.

</ul>

Line 209

</ul>

<li>SCSI improvements:

<ul>

<li>better <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=cd&sektion=4">cd(4)</a> detaching.

<li>better <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=st&sektion=4">st(4)</a> sense data and buf handling.

<li>eliminate excessive delays when starting DVD playing.

<li>ask only for minimal (i.e. 18 bytes) sense data, fixing usb devices.

<li>migrate to using bufq.

<li>always try READ CAPACITY 16 on devices claiming to be SCSI-3.

<li>many performance and reliability improvements as a result of new SCSI midlayer:

<ul>

<li>eliminate many unnecessary splbio/splx calls in SCSI drivers.

<li>eliminate many use after free's exposed by new SCSI midlayer.

<li>eliminate scsi_scsi_cmd(), simplifying calling inside SCSI midlayer.

<li>eliminate struct scsi_device.

<li>eliminate many uninitialized data references and invalid scsi_done() calls exposed by new SCSI midlayer.

<li>eliminate use of EAGAIN.

<li>eliminate almost all uses of NO_CCB and XS_NO_CCB.

</ul>

<li>Assorted improvements:

<a href="http://www.openbsd.org/macppc.html">macppc</a>

platforms were switched over to gcc4.

<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=newfs&sektion=8">newfs(8)</a> now makes FFS2 the default for partitions larger than INT_MAX blocks.

<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=dhcpd&sektion=8">dhcpd(8)</a> now includes the server id in NAK messages, as required by some

relays.

<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=disklabel&sektion=8">disklabel(8)</a> now aligns the start and end of FFS partitions on bsize boundaries where it can, to improve performance on 4096-byte block devices.

<li>by default, read and write caching is now turned on for non-USB scsi disks.

<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=getdirentries&sektion=2">getdirentries(2)</a> now checks to ensure that it doesn't wrap or truncate directory information on architectures where LONG is a different size from LONG LONG.

<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=disklabel&sektion=8">disklabel(8)</a> now ensures correct physical bounds and disk size are used when building a disklabel from saved ascii disklabel.

<li>it is again possible to build a bsd.rd that has DDB.

<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=pms&sektion=4">pms(4)</a> now works much better with various trackpads and over suspend/resume cycles.

<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=fdisk&sektion=8">fdisk(8)</a> now aligns the OpenBSD partition on a power of 2 block boundary to improve performance on 4096-byte block devices.

<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=nfsd&sektion=8">nfsd(8)</a> now logs start up errors to the system log as well as the console.

<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=nfsd&sektion=8">nfsd(8)</a> now errors out if given an invalid number of servers to run.

`installfrom' entry to the public mirror used while installing or upgrading.

<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sysmerge&sektion=8">sysmerge(8)</a> now automatically installs missing users and groups.
