<title>Installation of the kernel</title>
<para>Kernel version 2.6.10 has a security vulnerability that will allow user
processes to gain root privledges upon loading of a kernel module. See:
<ulink url="http://www.uwsg.iu.edu/hypermail/linux/kernel/0412.3/0679.html"/> for more information. The following patch fixes this problem:</para>
<screen><userinput>patch -Np1 -i ../linux-&linux-version;-security_fix-1.patch</userinput></screen>
<para>Prepare for compilation by running the following command:</para>
<screen><userinput>make mrproper</userinput></screen>
<!--NEW: the sed command has been removed-->
<para>If, in <xref linkend="ch-scripts-console"/>, you decided you want
to compile the keymap into the kernel, issue the command below:</para>
<screen><userinput>loadkeys -m /usr/share/kbd/keymaps/<replaceable>[path to keymap]</replaceable> > \
drivers/char/defkeymap.c</userinput></screen>
<para>Configure the kernel via a menu-driven interface:</para>
<screen><userinput>make menuconfig</userinput></screen>
<para>Compile the kernel image and modules:</para>
<screen><userinput>make</userinput></screen>
<para>Install the modules, if your kernel configuration uses them:</para>
<screen><userinput>make modules_install</userinput></screen>
<para>The path to the kernel image may vary depending on the platform you're
using. Issue the following command to install the kernel:</para>
<screen><userinput>cp arch/i386/boot/bzImage /boot/lfskernel-&linux-version;</userinput></screen>
<screen><userinput>cp System.map /boot/System.map-&linux-version;</userinput></screen>
<screen><userinput>cp .config /boot/config-&linux-version;</userinput></screen>
<para>If you are going to keep the kernel source tree around, you may want to
run <command>chown -R 0:0</command> on the
<filename class="directory">linux-&linux-version;</filename> directory to ensure all files are
owned by user <emphasis>root</emphasis>.</para>
