OPENROOT HAS NOT BEEN ABANDONED. CHECK HERE
Hello, I'm Evan Sarmiento, somehow you've managed to stumble upon this site. I'm a computer geek,
mostly interested in kernel hacking and trusted operating systems. One of my recent projects
involves providing security extensions for the FreeBSD operating systems. So, I suppose,
above all, my favorite aspect of the computer world is information security.
Linux Predictable Scheduling
As you can see I'm working on a number of projects all at the same time.
Right now, this is the one which I am paying the most attention to. I
am working with a CS professor from BU to create predictable scheduling
in the Linux 2.4.16 kernel by first porting DWCS to the 2.4.x series and then tweaking it a bit.
Progress posted here. We are using the MontaVista preempt
patch as a base.
I am working on a number of projects. First and foremost is PRFW, kernel hooks for
the FreeBSD operating systems. What is a hook? Is it related to captain hook? No.
A hook is a small snippet of code within a function that refrences another portion of code.
For example, in emacs, you're allowed to insert your own code into major and minor
modes using (add-hook). Basically, this patch allows the user to insert his own
code into various kernel functions and system calls.
One of the major incentives for using hooks is that it provides developers
who want to create security extensions an easy programming interface to use.
Openroot was my first project. It's a computer in which all users gain root access.
How is this possible? Through jail. As you can see, through my experiences
I've gotten to know a lot about jail() and have written on it.
I'm currently in high school at Boston University Academy, a private school on
Boston University's campus. I am taking Computer Science
at the University in addition to my normal coursework.
I have published a couple of articles. The first being, "Securing FreeBSD using Jail", which is
an article about how I protected and secured the Openroot computer. That article was published
in the May 2001 edition of SysAdmin magazine. The second article, a bit more technical,
was published in the September 2001 issue of Daemon News, entitled "Jail Internals". Just recently, an article of mine entitled "Systems Administration with SCSH", has been published in SysAdmin Magazine.
It is a featured article, so it resides both online and in the printed magazine. Read it here.
