Fix loop in ecryptfs-manager when there are no options (LP: #1695767)
Reproduce case:
1) User doesn't install openssl.
2) Run ecryptfs-manager and make selection 3.
It goes in the infinite loop...which means whatever selection you enter next
cannot end this command or alter your option.
Explanation for the patch:
Adding several lines to take such a case into consideration, through testing
whether "num_transitions" is set to zero or not we could prevent the infinite
loop. If it is set to zero, it will return -EINVAL because "num_transitions"
means how many options this command could show to users and zero means that
user has no option to choose.
