Yeah, I think everybody is a bit tired of - and burnt out by - these
patches, and they are subtler and somewhat more core than most are,
which makes the stakes a bit higher too, and the explanations can be a
bit more difficult.
I think everybody is entitled to being a bit snippy occasionally.
Definitely not just maintainers.
So by all means, push right back.
Anyway, I do think the patches I've seen so far are ok, and the real
reason I'm writing this email is actually more about future patches:
do we have a good handle on where these array index sanitations will
be needed?
Also, while array limit checking was obviously the official
"spectre-v1" issue, I do wonder if there are possible other issues
where mispredicted conditional branches can end up leaking
information?
IOW, is there some work on tooling/analysis/similar? Not asking for
near-term, but more of a "big picture" question..
