Dropbear server 0.50 stops listening to socket when started without stdin

[Laurent Pinchart]

Hi,

The 2007-07-19 commit ("Patch from Nicolai Ehemann to try binding before going 
to the background, so that if it exits early (because something's already 
listening etc) then it will return an exitcode of 1.") breaks Dropbear when 
started from init (busybox 1.6.1) with no console.

When no console is configured, init starts dropbear with stdin (fd 0) closed. 
The socket opened by listensockets() will then be assigned fd 0. The later 
call to daemon() will reassign fd 0, 1 and 2 to /dev/null, making dropbreak 
stop listening to the network.

I reverted the patch as temporary workaround. I'm not sure what a proper 
solution would be.

Please CC me when answering this e-mail.

Best regards,
