As someone actually affected by these reverts :-). Greg KH did not<br>
over react. These guys did not do the community a service. They did<br>
add vulnerabilities (those have been reverted since) and they did not<br>
tell us anything. I myself have left old code in the kernel when<br>
trying to get rid of some of my stuff. And I was not trying to inject<br>
a bug. They did not tell me anything I did not already know. It is<br>
easy to get bugs into the kernel. Let me link to the paper and their<br>
"contributions".<br>

VIII A<br>
By its nature, OSS openly encourages contributors. Com- mitters can<br>
freely submit patches without liability. We believe that an effective<br>
and immediate action would be to update the code of conduct of OSS,<br>
such as adding a term like “by submitting the patch, I agree to not<br>
intend to introduce bugs.” Only committers who agreed to it would be<br>
allowed to go ahead to submit the patches. By introducing the<br>
liability, the OSS would not only discourage malicious committers but<br>
also raise the awareness of potential introduced bugs for benign<br>
committers.<br>
--<br>
This is a mitigation. Have contributors claim they are not introducing<br>
bugs (at least intentionally).<br>
<br>
The rest of the mitigations are equally bizarre. They are not telling<br>
us anything we don't know. There is nothing original in this work<br>
(except for the human experimentation aspect of it.)<br>
<br>
Now let's talk about the negative impact. It is already hard enough to<br>
contribute to the linux kernel. It is built on trust. They have<br>
destroyed any trust we had in code coming from UMN. How do we know we<br>
are not being experimented for research? Like Greg pointed out, it is<br>
much easier for us to ignore all their stuff. I don't have enough<br>
seconds in my minute to get my day job done. On top of that, any new<br>
comer will have to face a much higher bar, making it even more<br>
hostile. (I actually see it as a negative, because it is easier to<br>
ignore the newcomer as opposed to doing the extra work. And generally<br>
most newcomers with some work turn out to be darn good contributors.)<br>
It will make it harder to look at non corporate contributions<br>
seriously.<br>
<br>
And as far as UMN is concerned, this is not the first time they have<br>
been involved in questionable experiments. The last time had much more<br>
serious consequences.<br>
