linux – 安全补丁上的自动内核重新编译?

 印度阿三17 2019-08-15

我正在使用Ubuntu 14.04并且非常喜欢我获得自动内核安全更新的事实.修补内核安全问题后,新版本将附带一个新软件包.我的计算机配置为每半小时扫描一次新的安全更新并自动安装它们.我不必看邮件列表或CVE,我得到补丁.这是一个很好的系统.

我在考虑运行grsecurity,但它们需要您修补并手动重新编译内核.这有点问题,因为我可能会错过Ubuntu上游提供的内核安全更新.

有没有办法自动化内核重新编译,将补丁文件添加到进程?

解决方法:

您确定自动内核重新编译需要吗?如果您使用Ubuntu存储库下载安全更新,则无需编译它们.否则你的问题就会遗漏这一点.

有几种方法可以自动编译内核.例如,检查此article

我在页面中添加引用:

# Automated Kernel Recompilation By Avinash Shankar 
# Note: This was done under RH-7.3 so plz verify the paths
# Warning: Please run the Script under Xwindows

#going to kernel sources directory:
echo Entering Kernel Source Directory................
cd /usr/src/linux-2.4/

#Cleaning dep files and objs:
echo Cleaning up Junk files..................
make clean

#Configuring your New Kernel:
echo Entering Graphical kernel config.....................
make xconfig

#Making the dependencies files:
echo Making the dependecies ..................
make dep

#Backing up old module files
echo All your module files and system.map files backed up ................ 
mv /lib/modules/2.4.18-3/modules.dep modules.dep.old
mv /usr/src/linux-2.4/System.map System.map.old

#Make a compressed kernel:
echo Compressing the kernel image ..............................................
make bzImage

#Copy the Image to /boot directory
echo Copying the bzImage to /boot Directory......................................................
cp /usr/src/linux-2.4/arch/i386/boot/bzImage /boot

#Make the modules :
echo Compiling the Modules ...............................
make modules

#Make the Installable modules used by the new kernel
echo Making the modules executable ...................................
make modules_install

#copy the System.map file to /boot
echo Copying System.map file to /boot ....................................
cp /usr/src/linux-2.4/System.map /boot

echo Thats it you are finished ! Cool now edit the lilo.conf or your grub.conf file
echo located in the /boot directory. Copy the kernel entries and replace kernel with
echo the bzImage file and the initrd entry with System.map

这些日子Live Kernel Patching也会让你的生活更轻松.不幸的是它仅适用于Ubuntu 16.04

Since the release of the Linux 4.0 kernel about 18 months ago, users
have been able to patch and update their kernel packages without
rebooting.
