[fuse-emulator-devel] Spectranet sockets bug

[Alistair <ali...@zx...>]

I've been investigating an issue with channels and streams in 
Spectranet, and discovered that there's a bug in the w5100 socket code.

There are two socket interrupts not being raised, namely the 'CON' 
interrupt (socket->ir |= 1 << 0;) when switching to 
W5100_SOCKET_STATE_ESTABLISHED in w5100_socket_process_accept, and 
'DISCON' (socket->ir |= 1 << 1;) when switching to 
W5100_SOCKET_STATE_CLOSE_WAIT in w5100_socket_process_read.

This prevents software detecting connect/disconnect events until a read 
occurs/fails.

I haven't exhaustively tested different states so there may be other 
conditions which differ from the hardware behaviour.

This along with the fixed-but-not-released flash memory emulation issue 
are causing problems for users, so getting a release out there with both 
issues fixed is quite important for spectranet development.
