<p>Bot (Edward's framework)</p>
<p><b>New page</b></p><div><br />
<br />
== Introduction ==<br />
This page describes the Protectec RAM File System (PRAM FS) feature.<br />
<br />
PRAM FS is a file system that enhances the security of system data in the<br />
presence of kernel bugs or rogue programs.<br />
<br />
The protected RAM file system will ordinarily remain consistent even if kernel data pointers<br />
are corrupted, or if the kernel starts executing unexpectedly in the wrong location.<br />
This is accomplished by making the RAM pages used by PRAM FS non-writable except during<br />
the actual file operations themselves.<br />
<br />
=== Rationale ===<br />
A single bug in the Linux kernel may cause catastrophic damage to a system.<br />
If a product holds irreproducible security keys, financial data, or account<br />
information, then loss of such data could render the product unusable, or worse.<br />
The customer could suffer financial or legal harm (from account theft or<br />
identity theft).<br />
<br />
It is not possible to guarantee with certainty that there are no bugs in the<br />
Linux kernel. However, it is possible to decrease the probability that a bug<br />
in the kernel will cause damage to a particular area of memory or storage. This<br />
protected area can then be used, with greater confidence, to hold sensitive user<br />
or product data.<br />
<br />
== References ==<br />
The home page for the PRAMFS project is at:<br />
http://pramfs.sourceforge.net/<br />
<br />
That site contains a LOT of detailed technical information and more explanation of<br />
the rationale for this feature.<br />
<br />
== Downloads ==<br />
<br />
=== Patch ===<br />
- [Patch for CELF version XXXXXX is *here*]<br />
- [Patch for 2.4.xx is *here*]<br />
- Patch for 2.6.7 is pending... (see [http://tree.celinuxforum.org/pipermail/celinux-dev/2004-September/000197.html celinux-dev archive message 197] for a recent submission to forum)<br />
<br />
=== Utility programs ===<br />
Pram fs can be created and populated using normal Linux filesystem utilities.<br />
<br />
== How To Use ==<br />
See the file <code>Documentation/filesystems/pramfs.txt</code> for instructions on its use (once the patch is applied).<br />
<br />
== Status ==<br />
Pramfs was submitted for consideration for inclusion in the 2.6.4 kernel, in March 2004.<br />
There was a thread of discussion [http://groups.google.com/groups?hl=en&lr=&threadm=1vJLx-4GI-57%40gated-at.bofh.it&rnum=1&prev=/groups%3Fhl%3Den%26lr%3D%26selm%3D1vJLx-4GI-57%2540gated-at.bofh.it here]<br />
<br />
There were a few, easily answered, concerns raised. But the patch was not accepted into mainstream.<br />
<br />
I talked to Andrew Morton about this in April, 2004, and he said the threshold is high for getting a new filesystem into the<br />
mainline kernel, because each filesystem adds incremental, ongoing, source maintenance overhead.<br />
<br />
== Sample Results ==<br />
[Examples of use with measurement of the effects.]<br />
<br />
== Future Work ==<br />
Here is a list of things that could be worked on for this feature:<br />
