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')

7abed14d63 Make compatible with the current Crypto++ master (#163) 
* Make compatible with the current Crypto++ master

* Add auto-config and build script. Not important, just a time-saver.

* Address compatibility with Crypto++ 6.0 release, while maintaining compatibility
with the older Crypto++ releases.

* Polish comments in cryptopp_byte.h. Forgot to include it to RandomGeneratorThread - fixed.

* Late at night - forgot to fix the .cpp files that used ::byte...

* Renamed auto-config-and-run script

* Added comments/description, and commented out "make check" that fails anyway

* Changed the include guard to match the rest of the .h files

* Delete build script

* Update ChangeLog.txt

* Update ChangeLog.txt

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

bbdd8a548b Special case treatment for traversals until exactly the last leaf has to load the last leaf to grow it. Before this commit, we just always loaded the last traversed leaf and checked its size. Now we only do so if it's the right border leaf. This saves us loading some leaves. 2016-07-17 10:16:09 +02:00
Sebastian Messmer
eab7cb1df4 Implement BlockStore::overwrite(). This is the last step in ensuring that the write() call doen't have to load leaves if they're only overwritten anyhow. 2016-07-16 11:42:06 +02:00
Sebastian Messmer
d80b95514e Traversal doesn't load leaves, but returns the key. This way, the write() call can (after a future commit) write to full leaves without loading them beforehand. 2016-07-15 20:12:24 +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

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

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

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

4d1f7a46b9 * Prevent rollback to the "newest" version of a client when this version was superseded by a version from a different client. 
* Use mutex/locks to secure access to KnownBlockVersions
 2016-06-26 22:15:52 -07:00
Sebastian Messmer
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
