Re: Fundamentals: what packets are dropped by the kernel?

And why?

The kernel drops packets when the contents appear inappropriate to him.
Of course what is "inappropriate" is in the eye of the beholder, so not
knowing Linus's political preferences, I don't know if it's leaning
towards pro-foxnews or pro-stalin or both.

PS: More seriously, the kernel drops packets when it can't keep up.
So the reason is "can't keep up because the streams of packets go
too fast compared to the rate at which the applications can process
them". As for which packets are dropped, I don't know what
heuristic uses Linux to select which ones to drop. I'd expect it
doesn't really choose consciously: when there's no space in the
incoming buffer it just drops the incoming pakets.
