514dbcb6c7 ClientId is not loaded/generated inside of KnownBlockVersions, but in CryDevice. This way, CryDevice also has access to the ClientID. This is later needed to recognize whether we're in a single-client or in a multi-client setting. 2016-06-26 22:15:52 -07:00
Sebastian Messmer
839a511c4d When an integrity violation is detected, any further access to the file system is blocked. This ensures that the user notices the integrity violation. 2016-06-26 22:15:52 -07:00
Sebastian Messmer
c84a230afd VersionCountingBlockStore is initialized with a flag, saying whether missing blocks are integrity errors. This flag is meant to be activated in a single-client scenario to have this additional integrity check. 2016-06-26 22:15:52 -07:00

03f59b69da Since 0.9.3-alpha set the config value cryfs.blocksizeBytes wrongly to 32768 (but didn't use the value), we have to add a workaround. 2016-03-26 23:56:56 +08:00
Sebastian Messmer
b9ac810414 - The version field in the config file is updated when the file system is opened with a newer CryFS version (i.e. it is migrated to the newer version). 
- We introduced a CreatedWithVersion field instead which gets the semantics the version field had before (i.e. which version of CryFS was the file system originally created with)
- Move VersionCompare to gitversion package

9c83d3b2a4 If CRYFS_FRONTEND=noninteractive is set in the environment, assume we're used by a tool and: 
- Don't ask for config. Use default settings for everything that is not specified as command line parameter.
- Don't ask for password confirmation. Password only has to be passed in once to stdin.

df041ac845 Fix a bug where deleting a directory could leave over some blocks. 
Details: Before, we allowed removing non-empty directories. Seems 'rm -rf' is trying to do that. Now, we return the correct error code ENOTEMPTY in this case, which causes that 'rm -rf' deletes the entries first.

f433da7dc1 Remove --extpass parameter, because that encourages tool writers to do bad things like storing a password in a file and using --extpass="cat filename".
