So Linus, you called the patches garbage when someone asked how we fixed the heap stack gap issue 7 years ago when you failed to. Can you provide any technical details demonstrating why that fix is garbage,
I didn't call "that fix" garbage. I called the grsecurity patches garbage. Why? They aren't split up, there has never been any effort by you to make them palatable to upstream, and when somebody else *dioes* try to make them palatable to upstream, you start crying about how people are taking advantage of your work (hah), and try to make them private instead. So tell me, why shouldn't I consider them garbage? They are. It's literally less work for people to re-implement things than look at your mixed-up patches, and YOU SEEM TO BE DOING THAT ON PURPOSE. Now, prove *me* wrong. Start trying to integrate your work upstream, and send individual patches with commit logs that can be integrated.
Put up or shut up, for once.
Indeed, Brad. Linus
