I'm not sure you can state that definitively just yet? So the real
question is whether saving the extra round-trip to the kernel is worth
the in-kernel complexity. Given that interleaved system calls are
_always_ a problem, I argue that it is worth it for at least the Station
case (and it will keep connection times even faster to boot). Isn't
minimizing the latency of connections the end goal here? I get that
there are trade offs and people have other opinions on what a good trade
off is.
But don't misunderstand, either solution is better than what we have
today. My argument is: "why close the door on a particular solution
until the costs are known?"
The rest, I'm not sure why you are worried about them now? For
station
there's a very clear & present use case. If such a clear and
present
use case is presented for AP or Mesh, then deal with it then.
Why would you not want to pass a random MAC for AP or Mesh modes? The
same reasons for MAC randomization apply for all those too, I'd think.
Umm, I was not arguing against doing that at all? All I said was that
no such use case was yet presented. For AP it isn't typically needed to
rapidly switch between MAC addresses while keeping the device UP. If
you think there's such a need, I'm happy to learn something new? Same
goes for Mesh really?
I don't see how this will not keep proliferating, and each new
thing
will come with its own dozen lines of code, a new feature flag,
etc.
Such is life? :)
Not really. It's the job of maintainers to balance all these things, to
step back and think of the bigger picture and the future rather than
just solving one particular use-case today.

through without the normal planning/architecture discussions that
accompany API changes. And that's not how the process typically works.
So who's attacking who now? We're trying to solve a long standing issue
that nobody has bothered to fix for years in a clean way. Something
that one of your projects would benefit from, btw.
I have a technical opinion about how it should look like. Johannes
might have a different opinion. In the end it is up to him and I can go
pound sand. So yes, I know how the process works ;)
