<p>(6 May 2005) An error in the default permissions on the <tt
class="FILENAME">/dev/iir</tt> device node, which allowed unprivileged local users to
send commands to the hardware supported by the <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=iir&sektion=4&manpath=FreeBSD+5.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">iir</span>(4)</span></a> driver.
Although the error was fixed prior to 5.4-RELEASE, it was applied too late in the release
cycle to be mentioned in the release notes. For more information, see security advisory

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">i386_get_ldt</span>(2)</span></a>
system call input arguments, which may allow kernel memory may be disclosed to the user
process, has been fixed. This bug was fixed prior to 5.4-RELEASE, although not in time to
be mentioned in the release notes. For more information, see security advisory <a
href="ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:07.ldt.asc"
target="_top">FreeBSD-SA-05:07.ldt</a>.</p>
<p>(6 May 2005) Several information disclosure vulnerabilities in various parts of the
kernel have been fixed in 5.4-RELEASE, although too late to be mentioned in the release
notes. For more information, see security advisory <a
href="ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:08.kmem.asc"
target="_top">FreeBSD-SA-05:08.kmem</a>.</p>
<p>(24 Jun 2005) The FreeBSD/sparc64 5.4-RELEASE should have stated that the
FreeBSD/sparc64 GENERIC kernel prior to the upcoming 6.0-RELEASE officially only supports
serial consoles. This is especially true for the FreeBSD/sparc64 5.4-RELEASE GENERIC
kernel because the ofw_console(4) driver which also provides limited indirect support for
graphical consoles has been replaced with the <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=uart&sektion=4&manpath=FreeBSD+5.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">uart</span>(4)</span></a> driver
in favor better serial support.</p>
<p>Due to this limitation to serial consoles the screen will stop working after the
message ``<samp class="COMPUTEROUTPUT">jumping to kernel entry at...</samp>'' is
displayed when trying to use the FreeBSD/sparc64 5.4-RELEASE GENERIC kernel with a
graphical console, while FreeBSD itself continues working actually.</p>
<p>If you want to use FreeBSD/sparc64 with a graphical console anyway you can do one of
the following:</p>
<ul>
<li>
<p>In case your machine is equipped with a Sun Creator, Sun Creator3D, or Sun Elite3D
frame buffer card and a Sun RS232 keyboard you can install FreeBSD/sparc64 5.4-RELEASE
with a serial console and afterwards compile a custom kernel with the following
additional options:</p>
<pre class="PROGRAMLISTING">
device sc
device creator
options KBD_INSTALL_CDEV
</pre>
<p>Additionally you have to enable the <tt class="FILENAME">tty[1-7]</tt> entries in <tt
class="FILENAME">/etc/ttys</tt> like so:</p>
<pre class="PROGRAMLISTING">
ttyv0 "/usr/libexec/getty Pc" cons25 on secure
# Virtual terminals
ttyv1 "/usr/libexec/getty Pc" cons25 on secure
ttyv2 "/usr/libexec/getty Pc" cons25 on secure
ttyv3 "/usr/libexec/getty Pc" cons25 on secure
ttyv4 "/usr/libexec/getty Pc" cons25 on secure
ttyv5 "/usr/libexec/getty Pc" cons25 on secure
ttyv6 "/usr/libexec/getty Pc" cons25 on secure
ttyv7 "/usr/libexec/getty Pc" cons25 on secure
</pre>
<p>This will yield native support for these keyboards and frame buffers including VTY
switching and X Window System. Note that this really requires at least FreeBSD/sparc64
5.4-RELEASE otherwise it will not work on most of the UltraSPARC models.</p>
</li>
<li>
<p>In case your machine is equipped with a ATI Mach64 frame buffer (found on-board in
e.g. Sun Blade 100/150 and Sun Ultra 5/10 as well as on Sun PGX8 and Sun PGX64 add-on
cards) or a PS/2 or a USB keyboard update to a FreeBSD/sparc64 6.0 from June 10 2005 or
later. If you use the stock GENERIC kernel and <tt class="FILENAME">/etc/ttys</tt> from
there no further action is required.</p>
<p>This will yield native support for these keyboards and frame buffers including VTY
switching and X Window System.</p>
</li>
<li>
<p>In case your machine is equipped with hardware other than those mentioned above or you
refuse to update to FreeBSD/sparc64 6.0 you can re-enable the ofw_console(4) driver as a
last resort. To do so build a custom kernel with the following additional options:</p>
<pre class="PROGRAMLISTING">
device ofw_console
device sab
device zs
</pre>
<p>and make sure to comment out the following kernel option:</p>
<pre class="PROGRAMLISTING">
device uart
</pre>
<p>This will yield limited indirect support for any graphical console hardware, however
with poor performance, and VTY switching as well as X Window System do not work with
this. Note that ofw_console(4) is not really MPSAFE and therefore can result in panics
under certain conditions.</p>
</li>
</ul>
