<h3>Name</h3>

<h3>Synopsis</h3>

<h3>Description</h3>
|
|
<p>
|
|
<tt>forkbomb</tt> does
|
|
<pre>
|
|
while (1) fork();
|
|
</pre>
|
|
doing a bit of additional checking similar to that done by
|
|
<A HREF=forktest.html>forktest</A>.

<h3>Requirements</h3>
|
|
<p>
|
|
<tt>forkbomb</tt> uses the following system calls:
|
|
<ul>
|
|
<li> <A HREF=../syscall/fork.html>fork</A>
|
|
<li> <A HREF=../syscall/getpid.html>getpid</A>
|
|
<li> <A HREF=../syscall/write.html>write</A>
|
|
<li> <A HREF=../syscall/_exit.html>_exit</A>
|
|
</ul>
|
|
</p>
|
|
|
|
<p>
|
|
We don't expect your system to withstand this without grinding to
|
|
a halt, but once your basic system calls are complete it shouldn't
|
|
crash. Likewise for after your virtual memory system is complete.
|
|
</p>
|
|
|
|
<p>
|
|
Note that this may turn out to be hard to achieve in practice. Don't
|
|
spend much time fixing problems <tt>forkbomb</tt> triggers that won't
|
|
arise under more normal operation. (If in doubt, consult your course
|
|
staff.)
