Seems like a number of patches were added (~190) and each had to be reviewed to ensure badness

https://web.archive.org/web/20210422144500/https://www-users.cs.umn.edu/~kjlu/papers/clarifications-hc.pdf (researcher deleted this paper from their site.)“Throughout the study, we honestly did not think this is human research, so we did not apply for an IRB approval in the beginning. We apologize for the raised concerns. This is an important lesson we learned---Do not trust ourselves on determining human research; always refer to IRB whenever a study might be involving any human subjects in any form. We would like to thank the people who suggested us to talk to IRB after seeing the paper abstract.”

The researchers issued an apology today 25 April: https://lore.kernel.org/lkml/CAK8KejpUVLxmqp026JY7x5GzHU2YJLPU8SzTZUNXU2OXC70ZQQ@mail.gmail.com/ *thanks to Zach Whittacker’s security mailing list..*


Thought provoking question for your show: is it realistically possible for an organization to build and scale a culture of code review that catches malicious insertions through (1) expert analysis; (2) adversarial mindset?

Introduction of bugs (meaningful or otherwise) caused more work for devs.

Is this better? Where’s the line on this?
