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.

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.

VersionCountingBlockStore::forEachBlock() has an integrity check checking that all expected blocks are still existing.

In case of an integrity violation, tell the user how they can reset integrity data.
2016-06-26 22:15:52 -07:00

When an integrity violation is detected, any further access to the file system is blocked. This ensures that the user notices the integrity violation.

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.

Throw an IntegrityViolationError exception instead of just logging integrity violations. This makes sure the user notices.

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
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

When a client deletes a block, it will never again accept it as a valid block.

* Block versions don't have to be globally nondecreasing, but only per client id. This solves potential synchronization conflicts in a multi-client setting.

Implement a VersionCountingBlockStore that checks that version numbers are nondecreasing. Currently, the block store is not used yet and the state is not stored over different runs of CryFS. This comes with future commits.

Hide fuse quirks inside the Fuse class.
...
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.

- 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

When the user specifies a block size for the file system, this is taken as the physical block size, not virtual block size.
