Follow-up Comment #5, patch #3796 (project lwip):
Funny, I did not read this patch before, but last weekend I was worried about
exactly that bit of code, accessing the pdb->snd_buf from the user thread.
As to your questions, Kieran:
- I don't think the patch is a solution, it only reduces the number of
possible conflicts as sndbuf is not read as often as before
- the two threads seem to be tcpip_thread and an application thread using
sockets or netconn-api.
- I think this IS a major problem, but it can only be solved by (at least
slightly) redesigning the netconn/socket api
I'm interested in going into this, but it could take some time...
