University of Minnesota Researchers Send Apology to Linux Kernel Mailing List
Posted: 2021-04-25 03:34:00 Source: http://rss.slashdot.org/~r/Slashdot/slashdotLinuxatom/~3/F1X_bO09SNE/university-of-minnesota-researchers-send-apology-to-linux-kernel-mailing-list
Earlier this week Greg Kroah-Hartman of the Linux kernel development team banned the University of Minnesota from contributing after researchers there submitted what he called "obviously-incorrect patches" believed to be part of a research project into whether buggy code would be accepted. Today the professor in charge of that project, as well as two of its researchers, sent an email to the Linux kernel mailing list saying they "sincerely apologize for any harm our research group did to the Linux kernel community." Our goal was to identify issues with the patching process and ways to address them, and we are very sorry that the method used in the "hypocrite commits" paper was inappropriate. As many observers have pointed out to us, we made a mistake by not finding a way to consult with the community and obtain permission before running this study; we did that because we knew we could not ask the maintainers of Linux for permission, or they would be on the lookout for the hypocrite patches. While our goal was to improve the security of Linux, we now understand that it was hurtful to the community to make it a subject of our research, and to waste its effort reviewing these patches without its knowledge or permission. We just want you to know that we would never intentionally hurt the Linux kernel community and never introduce security vulnerabilities. Our work was conducted with the best of intentions and is all about finding and fixing security vulnerabilities... We are a research group whose members devote their careers to improving the Linux kernel. We have been working on finding and patching vulnerabilities in Linux for the past five years... This current incident has caused a great deal of anger in the Linux community toward us, the research group, and the University of Minnesota. We apologize unconditionally for what we now recognize was a breach of the shared trust in the open source community and seek forgiveness for our missteps. We seek to rebuild the relationship with the Linux Foundation and the Linux community from a place of humility to create a foundation from which, we hope, we can once again contribute to our shared goal of improving the quality and security of Linux software... We are committed to following best practices for collaborative research by consulting with community leaders and members about the nature of our research projects, and ensuring that our work meets not only the requirements of the Institutional Review Board but also the expectations that the community has articulated to us in the wake of this incident. While this issue has been painful for us as well, and we are genuinely sorry for the extra work that the Linux kernel community has undertaken, we have learned some important lessons about research with the open source community from this incident. We can and will do better, and we believe we have much to contribute in the future, and will work hard to regain your trust. Their email also says their work did not introduce vulnerabilities into the Linux code. ("The three incorrect patches were discussed and stopped during exchanges in a Linux message board, and never committed to the code.") And the email also clarifies that their research was only done in August of 2020, and "All the other 190 patches being reverted and re-evaluated were submitted as part of other projects and as a service to the community; they are not related to the 'hypocrite commits' paper. These 190 patches were in response to real bugs in the code and all correct — as far as we can discern — when we submitted them... Our recent patches in April 2021 are not part of the 'hypocrite commits' paper either." UPDATE (4/25): Late Saturday night the kernel team's Greg Kroah-Hartman rejected the apology, writing that "the Linux Foundation and the Linux Foundation's Technical Advisory Board submitted a letter on Friday to your University outlining the specific actions which need to happen in order for your group, and your University, to be able to work to regain the trust of the Linux kernel community. "Until those actions are taken, we do not have anything further to discuss about this issue."
