|
Currently 083 waits for the nbd-fault-injector.py server to start up by
|
|
looping until netstat shows the TCP listen socket.
|
|
|
|
The startup protocol can be simplified by passing a 0 port number to
|
|
nbd-fault-injector.py. The kernel will allocate a port in bind(2) and
|
|
the final port number can be printed by nbd-fault-injector.py.
|
|
|
|
This should make it slightly nicer and less TCP-specific to wait for
|
|
server startup. This patch changes nbd-fault-injector.py, the next one
|
|
will rewrite server startup in 083.
