softhsm2-util: creating new slot/token fails on incorrect slot number

(reported by Paul Wouters from Red Hat)

After I imported my token from SoftHSM v1 I wanted to create a new slot; for testing I ran:

softhsm2-util --init-token --slot 6 --label "delme" --pin 1234 --so-pin 1234

This gives an error about the slot number. I guess it always has slotsused+1 slots.

Than I ran:

softhsm2-util --init-token --slot 1 --label "delme" --pin 1234 --so-pin 1234

This worked, however, softhsm2-util --show-slots shows that both slot 0 and slot 1 now have the "delme" label. So my slot 0 with imported token from SoftHSM v1 has become unusable.

Comment by Roland: I guess softhsm2-util needs to check the slot number or as Paul also suggested in his e-mail needs to have an option to create a new slot rather than explicitly having to find out which is the first empty slot.
