[lwip-devel] [bug #26267] Simultaneous close

[Kieran Mansley]

Follow-up Comment #13, bug #26267 (project lwip):

I've had another look and think I understand now: I was wrong about what
snd_max is.  I thought it was the maximum value that we could send, but it is
actually the maximum value we have sent.  snd_nxt can change to be smaller
when we retransmit things.  This is a problem because lots of code (e.g. stuff
I've written) uses snd_nxt where snd_max would be better.  I'm not sure why we
need both, so I'd quite like to get rid of snd_nxt.
