Description ZouNanHai 2005-05-25 02:22:50 UTC 
The follow program can hang a kernel when compile to 32 bit binary.

#include <unistd.h>
int main()
{
	void *p = (void *)0xFFFFE000UL;
	read(0, p, 4096);
}

I will post a patch to fix it

Comment 2 Olaf Kirch 2005-05-30 11:04:37 UTC 
Andi, is this patch correct? 
 
What about disclosure of this problem - can we include it in SP2?
Comment 3 Andreas Kleen 2005-05-31 14:16:45 UTC 
Patch is correct yes.
I don't think we need a disclosure time for this because it is only a DOS.
Hubert, please apply to all 2.6 trees.
Comment 4 Andreas Kleen 2005-05-31 14:24:43 UTC 
Small addon: it is not needed anymore on HEAD and 9.3 - a different change
there incidentially fixed that one too. That means it is only needed
on maintained 2.6 x86-64 trees.
Comment 5 Marcus Meissner 2005-06-01 08:22:47 UTC 
so missing on branches: 9.2, SLES9 SP1, SLES9 SP2.
Comment 6 Hubert Mantel 2005-06-02 12:15:04 UTC 
Ok, done. Kernels have been submitted for check in.
Comment 7 Ludwig Nussel 2005-06-02 14:16:02 UTC 
on my 9.3 x86_64 with the now cancelled kernel update it hangs just as it does 
on 9.2 so I'd say this has to go into 9.3 as well.
Comment 8 Ludwig Nussel 2005-06-02 14:51:53 UTC 
patch put into 9.3, lets hope it works.
Comment 9 Olaf Kirch 2005-06-07 10:05:40 UTC 
Is this fixed for SP2?
