0dbfdf3e2b When shrinking a tree, LeafTraverser takes care of decreasing tree depth, not DataTree anymore. This way, LeafTraverser is now responsible for increasing and decreasing depth as necessary. 2016-07-14 12:55:54 +02:00

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

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

a7f13ad7c1 When creating a file system, the user can choose whether to choose missing blocks as integrity violations. 2016-06-26 23:24:32 -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
491b277cee In case of an integrity violation, tell the user how they can reset integrity data. 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
Sebastian Messmer
e02021ecdc Throw an IntegrityViolationError exception instead of just logging integrity violations. This makes sure the user notices. 2016-06-26 22:15:52 -07:00

fd5dd2c6e1 New way of handling block deletions: Set last-update-client-id to zero instead of increasing version number. This has the same effect (i.e. invalidates all known block versions) and it additionally allows for checking in a local list whether a block is deleted or not. 2016-06-26 22:15:52 -07:00

1a72d3c226 Deleting a block doesn't set the version number to MAX_UINT64, but just increases it by one. This makes sure, that if (in case of a synchronization conflict) the block is reintroduced by another client, this is accepted. 2016-06-26 22:15:52 -07:00
Sebastian Messmer
5534b56ce3 When increasing the version number, don't only look at the version number in the block, but also at the last version number given to it by the current client. Ensure, the new version number is higher than both. 2016-06-26 22:15:52 -07:00
Sebastian Messmer
577c697856 When a client deletes a block, it will never again accept it as a valid block. 2016-06-26 22:15:52 -07:00

ea3de7360c * Block versions don't have to be globally nondecreasing, but only per client id. This solves potential synchronization conflicts in a multi-client setting. 
* Use cpputils::Serializer and cpputils::Deserializer instead of std::ifstream for storing/loading the block version list

fuse_main needs the program arguments as char ** instead of const char ** or (even better) vector<string>.
With this commit, we hide that inside the Fuse class. Everything outside handles these arguments as vector<string> and passes it as such to the Fuse class.

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).

- Move VersionCompare to gitversion package

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.
