A few days ago, Greg kroah Hartman, the administrator of Linux kernel, announced in a statement that he would blackmail the University of Minnesota, prohibit them from submitting code to Linux, and restore the code submitted by the University.
In fact, this is the result of last year's controversy. Professor Kangjie Lu of the University of Minnesota blocked the whole university. In order to write a paper to study the loopholes in the open source community, he submitted more than 200 buggy code to the Linux kernel in the past two years, and even deliberately introduced loopholes. As a result, he angered the Linux community.
Before that, Professor Lu Kangjie explained that the experimental method of this study did not cause any actual harm. He also helped fix three bugs by the way. Moreover, this study also applied to the University of Minnesota for IRB and obtained approval.
However, Professor Lu Kangjie's explanation has not been recognized by the Linux community. They think that the patches submitted by Lu Kangjie and others have no real value, and people who maintain Linux code have to audit these codes, which wastes time. Therefore, they no longer welcome people from the University of Minnesota to submit Linux code.
