Summary: TFTP gets confused if it gets bad packet from server
Description:
The tftp client has just 1 buffer, it uses same buffer for transmits and
receives. If it receives a bad packet from the server, the comments says
"fall through for bad packets, discard the packet, treat as timeout".
This is OK, but subsequently it should not use the information in the bad
packet (the packet is BAD). It does use this bad information, and ends up
sending garbage to the server. The servers tears down the tftp transfer.
The fix is simple, to maintain seperate send and receive buffers. A patch
file that does this is attached.
