Hi,
I just noticed that pre2.0.4 still doesn't support the secure deletion feature of the ext2 filesystem (which is disabled due to bad interaction with shared mappings). Are there any plans to put it back in the kernel before the 2.0 release? The Linus' comments in fs/ext2/truncate.c have some suggestions how to implement this.
Now that we have the kernel random number generator, it could be used here too, instead of the simple predictable one. If the random device is made a config option and it is disabled, we could simply fill the deleted disk blocks with zeros - if you are paranoid about such things, you probably have the random device enabled :-).
A program to clear all unused space on a filesystem would be nice...
Regards,
Marek
