[Bug 1582318] Re: amavis virus check fails when nvidia CUDA is on the same system

[Helge Doering]

Hi Christian,
I actually agree. Mostly because of the points you raised, but maybe even on a 
4th point. Most users use (and should use) a virtualized or container-ized 
environment, where in this case this bug also does not apply. I realized this a 
bit after I wrote the original comment. 
I still think, any "stable" distribution should be kinda... stable :) but I 
will agree, that pretty much nobody should have an amavisd + cuda drivers on 
one station (VM or bare-metal). Maybe a few private servers, but nothing 
serious. 

As for the new distribution; well sure it is fixed, but my question was
for xenial. I do retract my opinion of a "high gain". I still consider
it low risk, but without a warrant, it is probably not worth the risk.

Thanks for your reply and opinion!

Helge

[Bug 1582318] Re: amavis virus check fails when nvidia CUDA is on the same system

[ Christian Ehrhardt ]

Hi Helge,
You are right, the issue exists there.
But IMHO the backport has as SRU to Xenial has quite some regression risk and 
actually low gain.
Let me outline why I think so:

Looking at people that:
1. had amavisd running without - nvidia nvcc not installed
   => Things working fine
2. had amavisd running without - nvidia nvcc installed
   => amavisd is broken by this bug, but then can be fixed with a conscious 
config file change
3. had amavisd running without - norman AV nvcc installed
   => Things working fine WITH norman AV

Now if we would SRU something we would:
- not help #1 being not affected
- #2 was broken, so we fix something unused (and flagging all mails can be a 
thing as well since https://xkcd.com/1172/)
- for those people in #3 we would break a valid working setup

It is sort of unfortunate, but at least in my limited POV the risk actually 
outweighs the gain in this case.
Also setting up "new" Xenial should no more be a major tasks these days with 
Bionic being available for quite a while now.

just my 2 cents, feel free to discuss if you think otherwise.

Just encountered this bug on a xenial lts server. Isn't it supposed to be fixed 
there? 
If it's not should we open a SRU? It seems low risk and potentially high gain.

Debian lost the fix along the last uploads so I reopened the Debian bug
to ensure they get the fix.

[ChristianEhrhardt]

Thank you for your report, I checked around and can confirm that the
packaged nvidia-cuda-toolkit causes this conflict.

I added the disabling to the merge of amavisd-new which I prepared for
Yakkety as I think it is right to disable the "out-of-archive" solution
in this case.
