cryptsetup: craft a unique ID with the source device - #77
Merged

Conversation
If cryptsetup is called with a source device as argv[3], then craft the ID for the password agent with a unique device path. If possible "/dev/block/<maj>:<min>" is used, otherwise the original argv[3] is used. This enables password agents like petera [1] to provide a password according to the source device. The original ID did not carry enough information and was more targeted for a human readable string, which is specified in the "Message" field anyway. With this patch the ID of the ask.XXX ini file looks like this: ID=cryptsetup:/dev/block/<maj>:<min> [1] https://github.com/npmccallum/petera

If cryptsetup is called with a source device as argv[3], then craft the
ID for the password agent with a unique device path.
If possible "/dev/block/:" is used, otherwise the original
argv[3] is used.
This enables password agents like petera [1] to provide a password
according to the source device. The original ID did not carry enough
information and was more targeted for a human readable string, which
is specified in the "Message" field anyway.
With this patch the ID of the ask.XXX ini file looks like this:
