Yesterday, I wrote about a serious Linux kernel bug and fix. However, few readers like to know about patching running Linux kernel. Patching production kernel is a risky business. Following procedure will help you to fix the problem. Step # 1: Make sure your product is affected First find out if your product is affected [...]
Linux kernel version from 2.6.17 to 18.104.22.168 all are affected because of vmsplice bug. The exploit code can be used to test if a kernel is vulnerable and it can start a root shell. => Debian Bug report logs => Fix 1 and Fix 2 Update: See how to apply a patch to kernel source [...]
kfsmd is an interesting tool to keep track of changes in your filesystems. This tool based upon inotify which is a Linux kernel subsystem that provides file system event notification. Useful for file auditing. From the article: Applications can ask the Linux kernel to report changes to selected files and directories. I created the Kernel [...]
Linux creator Linus Torvalds, in an interview being made public by the Linux Foundation Tuesday, stressed that version 2 of the GPL (GNU General Public License) still makes the most sense for the Linux kernel over the newer GPL version 3. Among GPL 3 highlights are protections against patent infringement lawsuits and provisions for license [...]
If you have 4 GB or more RAM use the Linux kernel compiled for PAE capable machines. Your machine may not show up total 4GB ram. All you have to do is install PAE kernel package.

Linus Torvalds writes: Yeah, it got delayed, not because of any huge issues, but because of various bugfixes trickling in and causing me to reset my “release clock” all the time. But it’s out there now, and hopefully better for the wait.Not a whole [...]
The stap program is the front-end to the Systemtap tool. It accepts probing instructions (written in a simple scripting language), translates those instructions into C code, compiles this C code, and loads the resulting kernel module into a running Linux kernel to perform the requested system trace/probe functions. SystemTap provides free software (GPL) infrastructure to [...]
