[lwip-devel] [bug #52403] netconn: FIN may be sent instead of RST when TCP netconn is closed with pending data in recv_mbox

[Simon Goldschmidt]

Update of bug #52403 (project lwip):

             Open/Closed:                    Open => Closed

Follow-up Comment #6:

Fixed 1) in tcp_close_shutdown(), this was indeed wrong.

Fixed 2) in git master (actually, TCP MSG_PEEK did not work at all since march
on git master). In contrast to 2.0.x, in the new code, the window is only
updated for data read from the socket (not peeked and not when read from the
netconn), so data left in 'lastdata' should have no influence on the RST
handling.
