7e56c46bb0 CryFS tells the operating system to not swap the encryption key to the disk (note: this is best-effort and cannot be guaranteed. Hibernation, for example, will still write the encryption key to the disk) 2017-09-05 00:43:43 +01:00

679b14a4d8 * Allow mounting using system mount tool and /etc/fstab (e.g. mount -t fuse.cryfs basedir mountdir) 
* Pass fuse options directly to cryfs (i.e. 'cryfs basedir mountdir -o allow_other' instead of 'cryfs basedir mountdir -- -o allow_other')

e37d84a3d6 fspp::Dir, fspp::File and fspp::Symlink don't inherit from fspp::Node anymore. This allows file systems to return a generic fspp::Node instead of a concrete subclass when the operation doesn't need to know what type of node it is. 2017-01-21 19:16:35 +00:00

9e9369b9ed Performance optimization: When removing or shrinking a tree, we don't load/read leaves anymore. Loading inner nodes is enough to get all block IDs and then we can delete the leaves from their IDs without loading them. 2016-07-13 11:27:31 +02:00

Sebastian Messmer
397de9372f Each blob stores a parent pointer (i.e. the ID of the directory that contains this blob). This stores the directory structure in a conflict-proof way and can be used to resolve such conflicts. 2016-06-27 18:22:13 -07:00

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
