[SR-Users] receive_fd(): EOF

[Daniel-Constantin Mierla]

You changed the source code, so send the diff, not the entire files, in
order to be easier to see what code you wrote.

Anyhow, the log messages say there is a buffer overflow -- you wrote
more into the buffer than the buffer size.

Cheers,
Danie
