 Posted: Thu Aug 15, 2002 3:02 am Post subject: Kernel Panic - dos attack? |
 |
|
My machine is otherwise stable,
I've been running gentoo on it for over 2 months,
zero problems except for the glxgears issue
and just now,
as a regular user I can cause a kernel panic
with recent discussions elsewhere on security matters,
i wonder this falls into the 'significant bug' or 'sh!t happens' category
or maybe its just my setup...
so anyone else wants to try... it happened with the disk io benchmark/testing tool 'bonnie' located at
http://www.textuality.com/bonnie/
all i did was...

Does this happen using vanilla-sources? I've gotten spurious kernel oopes in SMP code using gentoo-sources-2.4.19-r7 that I don't get under 2.4.18 or 2.4.19.

The gentoo kernel sources panicked my machine the first day, and I went straight back to vanilla, no problems since.  I did try all sorts of fancy options with the gentoo sources though... |

Does this happen using vanilla-sources? I've gotten spurious kernel oopes in SMP code using gentoo-sources-2.4.19-r7 that I don't get under 2.4.18 or 2.4.19. |
I haven't tried vanilla sources...
the gentoo kernel is (so far... and ive done some heavy duty dvd ripping/re-encoding) rock solid. If that changes, I'll try the vanilla and report back with how it handles the 'bonnie' thing
as for it being a problem with bonnie... imo a program run as a regular user, no matter how badly written, should not have the ability to cause a kernel panic

Correct, except that gentoo-sources-2.4.19-r7 is not tested nearly as much as 2.4.18 or 2.4.19. It's a kernel prepatch -- not an official 'stable' release -- and as such it can and does contain a number of obscure bugs. bonnie may be aggravating that situation.
I have seen a number of problems that were resolved by moving to vanilla-sources. Please give it a try.

On further testing,
my machine at work is an athlon 1000, gentoo kernel
and it completes the bonnie benchmark fine...
so its something with my home comp configuration.

I will continue to insist that you give vanilla-sources a try. If you do "emerge \=vanilla-sources-2.4.18", you won't have to download any new files either, since gentoo-sources-2.4.19-r7 patches the 2.4.18 tarball.
If bonnie breaks a vanilla kernel, then we can collectively try to think of other possibilities. However, a kernel bug is quite probable, and moving to vanilla-sources would test that theory.

To give this thread an ending...
I tried with vanilla sources and it had the same results.
(This is also related to the glxgears prollems I was having)
Turns out I was overheating.
Stock heatsink/fan ...
I've got a tt volcano 6cu on there now and everythings cool
