2015-11-27diriv: Convert filename encryption users to dirivJakob Unterwurzacher
2015-11-25diriv: Transactionally delete gocryptfs.diriv in RmdirJakob Unterwurzacher
2015-11-25diriv: Create gocryptfs.diriv in every directoryJakob Unterwurzacher
2015-11-14Run go fmt and go vetJakob Unterwurzacher
2015-11-09Add "-q" (quiet) flagJakob Unterwurzacher
2015-11-08Handle ENOSPC errors better by preallocating the space before writingJakob Unterwurzacher
Prevent the case that we run out of space in the middle of writing a block - that would leave a corrupt block behind.
2015-11-03Centralize path filter decision in CryptFS.IsFiltered()Jakob Unterwurzacher
2015-11-03Implement PlainTextNames modeJakob Unterwurzacher
Also, forbid access to "gocryptfs.conf" in the root dir.
2015-11-01Remove code detected by "deadcode"Jakob Unterwurzacher
go get github.com/remyoudompheng/go-misc/deadcode
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.
2015-10-06Use block number as authentication dataJakob Unterwurzacher
2015-10-04Utimens: Use UtimesNano instead of FutimesJakob Unterwurzacher
Futimes() only takes microsecond resolution while the FUSE call Utimens() wants nanosecond precision. This is why UTIME_OMIT did not work - this change fixes the xfstests generic/258 test failure. The go library does not provide a FutimesNano() function which is why I use UtimesNano() on /proc/self/fd/n. This is what the Go library does in Futimes().
2015-10-04fallocate: return ENOSYSJakob Unterwurzacher
The implementation was incomplete, disable fallocate completely for now. See https://github.com/rfjakob/gocryptfs/issues/1 Fixes xfstests generic/075
2015-10-04truncate: Fix bug that caused xfstests generic/030 to failJakob Unterwurzacher
The bug was caused by using cipherOff where plainOff should have been used. Renamed the symbols for less confusion.
2015-10-04Truncate: Logging improvements, show number of blocks as floatJakob Unterwurzacher
2015-10-04Fix Trucate() bug causing files to be too smallJakob Unterwurzacher
Uncovered by running xfstests generic/014 several times
2015-10-04Run go fmtJakob Unterwurzacher
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.
2015-10-04Utilize file hole passtrough capability in Truncate()Jakob Unterwurzacher
Cuts down the runtime of xfstests generic/014 from 1822 seconds to 36 seconds
2015-10-04Zero-pad last block if a file hole is created on Write()Jakob Unterwurzacher
Fixes TestFileHoles test
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.
2015-09-30tests: Add append testJakob Unterwurzacher
2015-09-30Implement Truncate() + TestJakob Unterwurzacher
2015-09-30debug: Log encrypted filenameJakob Unterwurzacher
2015-09-19Fix Chown parameter orderJakob Unterwurzacher
2015-09-17Fix read benchmarkJakob Unterwurzacher
2015-09-16Fix symlink size reportingJakob Unterwurzacher
2015-09-13Don't warn about "gocryptfs.conf" in the ciphertext root dirJakob Unterwurzacher
2015-09-13Encrypt key with scrypt-hashed passwordJakob Unterwurzacher
2015-09-09Fix File.GettAttr() size reportingJakob Unterwurzacher
The too-large reported value broke mmap (applications saw appended zero bytes) Also * Add locking for all fd operations * Add "--debug" command line switch
2015-09-08Explain both frontends in readmeJakob Unterwurzacher
Also, re-enable openssl and disable debug messages so testing gocryptfs is less painful
2015-09-08Fix panic on absolute symlinkJakob Unterwurzacher
2015-09-08tests: add TestCiphertextRangeJakob Unterwurzacher
2015-09-08Fix append issueJakob Unterwurzacher
2015-09-08More debug logging, improve main_test.go (do not use all-zero content)Jakob Unterwurzacher
2015-09-08Add pathfs frontend, part IIJakob Unterwurzacher
Fix issues in read and write paths. Now passes selftest.
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
