2015-11-03config: Introduce ext4-style feature flagsJakob Unterwurzacher
// List of feature flags this filesystem has enabled. // If gocryptfs encounters a feature flag it does not support, it will refuse // mounting. This mechanism is analogous to the ext4 feature flags that are // stored in the superblock. FeatureFlags []string
2015-11-01Refactor ciphertext <-> plaintext offset translation functionsJakob Unterwurzacher
Move all the intelligence into the new file address_translation.go. That the calculations were spread out too much became apparent when adding the file header. This should make the code much easier to modify in the future.
2015-11-01Add file header (on-disk-format change)Jakob Unterwurzacher
Format: [ "Version" uint16 big endian ] [ "Id" 16 random bytes ] Quoting SECURITY.md: * Every file has a header that contains a 16-byte random *file id* * Each block uses the file id and its block number as GCM *authentication data* * This means the position of the blocks is protected as well. The blocks can not be reordered or copied between different files without causing an decryption error.

2015-10-04intraBlock: Rename Offset to SkipJakob Unterwurzacher
"Offset" is unclear whether it is an offset from the start of file or start of block. "Skip" seems much better.
2015-10-04Add BlockNoPlainOff() and BlockNoCipherOff() + testJakob Unterwurzacher
Also, fix key, it is now []byte, not [16]byte
2015-10-04Fix xfstests generic/030 failureJakob Unterwurzacher
The actual fix is oldSize := f.cfs.PlainSize(uint64(fi.Size())) the rest is logging improvements
2015-10-03debug: log inode number instead of encrypted filenameJakob Unterwurzacher
Makes the log output smaller and more readable.
2015-10-03Implement file hole passtroughJakob Unterwurzacher
Fixes xfstests generic/010 Note that file holes are not authenticated,
2015-09-30Implement Truncate() + TestJakob Unterwurzacher

2015-09-08Add pathfs frontend (uses go-fuse instead of bazil-fuse), part IJakob Unterwurzacher
Currently fails main_test.go, will be fixed in part II
2015-09-06Add OpenSSL support for file content encryption/decryptionJakob Unterwurzacher
This brings streaming read performance from 30MB/s to 81MB/s (similar improvement for writes)
