2015-10-04Switch nonce generation to purely randomJakob Unterwurzacher
The old implementation of counting up from a random starting point had the problem that is allowed an attacker to find out the write order of the blocks.
2015-10-04Clean up openssl benchmarkJakob Unterwurzacher
2015-10-04tests: simplify namesJakob Unterwurzacher
main_test_tmp -> tmp main_benchmark.bash -> benchmark.bash
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

2015-10-04Remove ClueFS frontendJakob Unterwurzacher
Development has focused on PathFS for some time now and things are working well.
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
2015-10-04Add BlockNoPlainOff() and BlockNoCipherOff() + testJakob Unterwurzacher
Also, fix key, it is now []byte, not [16]byte
2015-10-04tests: add TestFileHolesJakob Unterwurzacher
Create a file with holes by writing to offset 0 (block #0) and offset 4096 (block #1). This test currently fails.
2015-10-04Fix xfstests generic/030 failureJakob Unterwurzacher
The actual fix is oldSize := f.cfs.PlainSize(uint64(fi.Size())) the rest is logging improvements
2015-10-03Add daemonization shell scriptJakob Unterwurzacher
2015-10-03debug: log inode number instead of encrypted filenameJakob Unterwurzacher
