Re:[uml-user] File Corruption bug...

[James W M. <mcm...@ju...>]

Would this be mounted via hostfs
If it is there was a recently fixed bug where the mmap function did not
clear the buffer following the end of file which could appear as
corruption.

Hum, you are using 2.4.20-6um which is the most recent.

You may want to try 2.4.20-5um as Jeff changed the ubd driver to separate
out the COW functions from the ubd functions.
One of my computers may be having problems with 2.4.20-6um but I was
still checking to make sure I had not done something wrong, but it is
possible that something broke during Jeff's refactoring.

I assume that the problem only appears when you try to unpack under UML
and it works fine on the host.
I also assume that you have a SMP host system and are not using SKAS mode
in your host kernel, are the other hosts you mentioned also SMP and were
any of them SKAS or were all of them SKAS perhaps?

I hope this helps
