2016-02-06Rename DirIVCacheEnc to just DirIVCacheJakob Unterwurzacher
...and unexport dirIVCache
2016-01-31Don't print plain text directory name in "Invalid name" warningJakob Unterwurzacher
2016-01-24Only warn once for unsupported fallocate(2) and truncate(2)Jakob Unterwurzacher
Also, print the inode number in Ftruncate warnings.
2016-01-20Convert logging to standard Go log.LoggerJakob Unterwurzacher
This is in preparation of logging to syslog.
2015-12-19Increase GCM IV size from 96 to 128 bitsJakob Unterwurzacher
This pushes back the birthday bound for collisions to make it virtually irrelevant.
2015-12-19diriv: handle directory rename over directoryJakob Unterwurzacher
If an empty directory is overwritten we will always get ENOTEMPTY as the "empty" directory will still contain gocryptfs.diriv. Handle that case by removing the target directory and trying again. Fixes issue #10
2015-12-13go fmtJakob Unterwurzacher
...and minimal comment changes.
2015-12-11Rmdir: handle creating and removing unreadable directoriesJakob Unterwurzacher
This patch also splits off Mkdir and Rmdir into its own file. Fixes issue #8, thanks to @diseq for the bug report.
2015-12-10Add missing PlaintextNames checks in OpenDir, Mkdir, Rmdir, initDirJakob Unterwurzacher
Plaintextnames support has bitrotted during the DirIV additions, this needs test cases. Will be added in a future patch. Fixes issue #9.
2015-12-08Add EME filename encryption & enable it by defaultJakob Unterwurzacher
2015-12-06Fix rename, was broken broken by DirIV introductionJakob Unterwurzacher
As it was, CIPHERDIR was prepended twice, causing every rename to fail with ENOENT.
2015-11-29Run go fmtJakob Unterwurzacher
2015-11-29Add single-element cache for DirIV lookupJakob Unterwurzacher
Another 3x performance boost for applications that walk the directory tree. Excerpt from performance.txt: VERSION UNTAR LS RM v0.4 48 1.5 5 v0.5-rc1 56 7 19 v0.5-rc1-1 54 4.1 9 v0.5-rc1-2 45 1.7 3.4 <---- THIS VERSION
2015-11-29OpenDir performance: Read DirIV once and reuse it for all namesJakob Unterwurzacher
Formerly, we called decryptPath for every name. That resulted in a directory walk that reads in all diriv files on the way. Massive improvement for RM and LS (check performance.txt for details) VERSION UNTAR RM LS v0.4 48 5 1.5 v0.5-rc1 56 19 7 v0.5-rc1-1 54 9 4.1 <---- THIS VERSION
2015-11-28diriv: also support old CBC symlinkJakob Unterwurzacher
2015-11-28diriv: fix Symlink() and Readlink()Jakob Unterwurzacher
Both were missing adaptions for diriv usage resulting in broken functionality
2015-11-28diriv: fix readdirJakob Unterwurzacher
It decrypted all file names using the root directory iv
2015-11-28diriv: use "DirIV" flag to discern and support mounting old filesystemsJakob Unterwurzacher
2015-11-27Run go fmtJakob Unterwurzacher
2015-11-27diriv: Move WriteDirIV() to cryptfs; add locking to Mkdir, RmdirJakob Unterwurzacher
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
2015-11-03Centralize path filter decision in CryptFS.IsFiltered()Jakob Unterwurzacher
2015-11-03Implement PlainTextNames modeJakob Unterwurzacher
Also, forbid access to "gocryptfs.conf" in the root dir.
2015-11-01Refactor 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.
2015-10-04Run go fmtJakob 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
2015-09-08Fix panic on absolute symlinkJakob 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
