[lwip-devel] [patch #6865] SO_REUSEADDR for TCP

[Simon Goldschmidt]

Update of patch #6865 (project lwip):

                  Status:               Need Info => Done                   
             Open/Closed:                    Open => Closed

Follow-up Comment #18:

Done. tcp_bind() now virtually allows any combination of double-used
ports/addresses since there is no way to check it at that point (since the
remote IP/port is unknown at that point).

Instead, tcp_connect() checks for a unique 5-tuple for active connections,
passive connections rely on the remote IP/port being unique.

I did it this way after checking what linux allows and what it doesn't, so
it's a bit different to other OSes (especially windows, I guess), but since
the (opengroup-)spec doesn't say much about the details, that's OK with me.

Please reopen if there are still problems with SO_REUSEADDR.
