I even tried to reach a middle ground understanding and you've doubled down asserting that there's no world in which the author's lived experience can be valid because he didn't initially add a signed-off-by line. If you actually read the post, the author spends most of the time describing the issue and the fix. He takes maybe 5 sentences to explain how he didn't feel like his contribution was accepted in a considerate manner and it's discouraged him from making further contributions. It's not some grand 1000 work attack and if anybody has the thick skin to withstand one of those it's the goliath of the LKML.
And the author pretty explicitly states that he did go back and forth with the maintainer privately and provided a fixed up patch which addressed feedback he'd received on the first patch (presumably with a signed-off-by line, now) and the maintainer still didn't want to give credit. You've conveniently ignored this part of the narrative entirely. This really discredits your whole "it was a quick security list issue and wasn't even formatted properly lol this guy obviously deserves no respect for engaging the security list and generally being a noob" angle.
Everything that we know points to the contributor trying to act responsibly by engaging the security list first since they didn't know the security impact of a possibly major security issue (overwriting the stack of a traced process). I completely fail to understand your logic whereby doing so means the OP obviously fucked up and deserves to have his contribution belittled and stolen and that's just life on the LKML... seriously I think it's time you just admit you're in the wrong here and stop shit posting.
We've already been through the whole "you shouldn't need to have thick skin and tolerate insults and disrespect to contribute to the linux kernel" as a community. Linus even took a leave of absence over this shit. Your stance that this stuff is acceptable and par for the course is no longer the status quo. Grow up.
I've been trying to browse this thread and before I started checking usernames I got the the impression that there's a whole world of maintainers who think it's acceptable to be disrespectful to people spending a lot of time and effort on trying to contribute.
It turns out it's just a few (very prolific) people creating a lot of negative noise across the thread. Thank you for stepping up.
Whatever work Ariel has done has been grossly negated by this attack piece, besides the fact that it omits and/or materially alters the nature of the interaction. At no point did the maintainer leave any doubt as to their intentions, nor was anything that happened unexpected. If you start off your career as a contributor to the Linux kernel by mailing the security mailing list then that requires you to do your homework because otherwise things will be out of your hands. If that was the OPs intention he would have done better to leave the security mailing list out of it and first strike up a conversation with the maintainer about what the best way to start contributing is (there are guides as well, but since he clearly wanted to target this particular subsystem that would have been a valid approach in my opinion).
It's an attack to me because (1) it mentions an exchange that names individuals and (2) it does so using some very expensive words ('robbery'). That's not the kind of accusation that you make lightly and in this case I think it is vastly misrepresenting what actually happened. You only have to read the responses in this thread to OPs misrepresented account to realize how much effect such a thing can have.
What happened is that someone new chose a wrong and ultimately broken way to submit a patch to LKML and that the maintainers did their best to get maximum mileage out of it without wasting time on formalities. Note that these are pretty busy people, to put it mildly and by mailing the security list you've just made them that much more busy still (even though, technically the patch was an improvement it still required work that then ended up becoming high priority).
As for Ariel being a contributor: according to LKML he submitted a proposed patch that needed work, wasn't properly signed off and according to the git commit log he created a report. That's the extent of it, and that's fairly accurate given the standards for these things.
If you want to argue that those standards need work then you may well have a point. But within the current framework this all was 'business as usual' and totally expected.
