2017-03-05cryptocore: use eme v1.1 interfaceJakob Unterwurzacher
Version 1.1 of the EME package (github.com/rfjakob/eme) added a more convenient interface. Use it. Note that you have to upgrade your EME package (go get -u)!
2017-02-16tests: reverse: check Access() callJakob Unterwurzacher
2017-02-16fusefrontend_reverse: handle .name files in Access()Jakob Unterwurzacher
These were currently passed to decryptPath() were it caused a warning.
2017-01-03reverse: add single-entry path cacheJakob Unterwurzacher
Speeds up the "ls -lR" benchmark from 2.6 seconds to 2.0.
2017-01-03reverse: factor out rDecryptNameJakob Unterwurzacher
This prepares the code for the introduction of a path cache.
2016-12-10Replace all calls to naked panic() with log.Panic()Jakob Unterwurzacher
We want all panics to show up in the syslog.
2016-11-17fusefrontend: upgrade wlockMap to use device AND inode numberJakob Unterwurzacher
If there are multiple filesystems backing the gocryptfs filesystems inode numbers are not guaranteed to be unique.
2016-11-10ctlsock: prevent panic on invalid decrypt requestJakob Unterwurzacher
2016-11-10ctlsock: implement EncryptPath for reverse mode, add testsJakob Unterwurzacher
2016-11-10reverse: fix longname decoding bugJakob Unterwurzacher
This could have caused spurious ENOENT errors. That it did not cause these errors all the time is interesting and probably because an earlier readdir would place the entry in the cache. This masks the bug.
2016-11-10Fix golint warningsJakob Unterwurzacher
$ golint ./... | grep -v underscore | grep -v ALL_CAPS internal/fusefrontend_reverse/rfs.go:52:36: exported func NewFS returns unexported type *fusefrontend_reverse.reverseFS, which can be annoying to use internal/nametransform/raw64_go1.5.go:10:2: exported const HaveRaw64 should have comment (or a comment on this block) or be unexported
2016-11-10ctlsock: add initial limited implementationJakob Unterwurzacher
At the moment, in forward mode you can only encrypt paths and in reverse mode you can only decrypt paths.
2016-11-01Add support for unpadded base64 filenames, "-raw64"Jakob Unterwurzacher
Through base64.RawURLEncoding. New command-line parameter "-raw64".
2016-10-24Fix misspellingsJakob Unterwurzacher
Close https://github.com/rfjakob/gocryptfs/issues/54
2016-10-09reverse: add panics against API abuseJakob Unterwurzacher
These should help prevent later programming errors.
2016-10-08reverse: gocryptfs.conf was missing from the directory listingsJakob Unterwurzacher
Fix the test for that and add checks in example_filesystems_test.
2016-10-08reverse: merge config translation check into isTranslatedConfigJakob Unterwurzacher
Also get rid of useless isFiltered function.
2016-10-08reverse: make gocryptfs.conf mapping plaintextnames-awareJakob Unterwurzacher
Only in plaintextnames-mode AND with the config file at the default location it will be mapped into the mountpoint. Also adds a test for that.
2016-10-05reverse: initialize the longname cache only when reverse mode is usedJakob Unterwurzacher
Gets rid of the idling longnameCacheCleaner thread in "normal" mode.

2016-10-04fusefrontend_reverse cast Stat_t.Dev to uint64 (#44)Romain
The [Stat_t.Dev](https://golang.org/pkg/syscall/#Stat_t) docs say `Dev` is a `unit64`, but on [macOS amd64](https://golang.org/src/syscall/ztypes_darwin_amd64.go) it's an `int32`.
2016-09-29reverse: use per-purpose nonce generationJakob Unterwurzacher
Also pull all the deterministic nonce code into fusefrontend_reverse to greatly simplify the normal code path.
2016-09-28reverse: move newDirIVFile into virtualfile.goJakob Unterwurzacher
After all, is's a virtual file.
2016-09-25Implement changes proposed by gosimple.Jakob Unterwurzacher
Also delete the unused "dirIVNameStruct", found by deadcode.
2016-09-25tests: enable all go vet checksJakob Unterwurzacher
...and fix reported errors: internal/fusefrontend_reverse/rfile.go:40: github.com/rfjakob/gocryptfs/internal/contentenc.FileHeader composite literal uses unkeyed fields internal/fusefrontend_reverse/rfs.go:249: github.com/hanwen/go-fuse/fuse.DirEntry composite literal uses unkeyed fields internal/fusefrontend_reverse/rfs.go:264: github.com/hanwen/go-fuse/fuse.DirEntry composite literal uses unkeyed fields
2016-09-25contentenc: rename constant "IVBitLen" to "DefaultIVBits" and clarify commentJakob Unterwurzacher
128-bit IVs are NOT used everywhere.
2016-09-25reverse: add symlink encryption and Readlink supportJakob Unterwurzacher
2016-09-25reverse: derive file ID and block IVs from file pathsJakob Unterwurzacher
2016-09-25reverse: add longnameParentCacheJakob Unterwurzacher
findLongnameParent has to read the whole directory to find the right file; add a simple cache to avoid most directory scans.
2016-09-25reverse: resolve long names in Open and GetAttrJakob Unterwurzacher
The last patch added functionality for generating gocryptfs.longname.* files, this patch adds support for mapping them back to the full filenames. Note that resolving a long name needs a full readdir. A cache will be implemented later on to improve performance.
2016-09-25reverse: transform long names in OpenDirJakob Unterwurzacher
2016-09-25reverse: use dynamic inode numbersJakob Unterwurzacher
...with stable mappings for hard-linked files.
2016-09-25contentenc: add GCM-SIV supportJakob Unterwurzacher
Also add ReverseDummyNonce nonce generation.
2016-09-25cryptocore: add support for GCM-SIVJakob Unterwurzacher
2016-09-25reverse: fix GetAttr for gocryptfs.confJakob Unterwurzacher
And also don't return the encrypted version of .gocryptfs.reverse.conf in readdir.
2016-09-25reverse: add gocryptfs.conf passthroughJakob Unterwurzacher
2016-09-25reverse: get rid of debug messageJakob Unterwurzacher
2016-09-25reverse: gocryptfs.diriv content was generated from wrong pathJakob Unterwurzacher
Should be derived from the directory name only.
2016-09-25reverse: rename readFile to clearer readBackingFileJakob Unterwurzacher
Also refactor the header generation for nicer code.
2016-09-25reverse: implement dynamic dirivJakob Unterwurzacher
Introduce a unique per-directory diriv that is generated by hashing the encrypted directory path.
2016-09-25reverse: generate file header for Read()Jakob Unterwurzacher
Also create virtual gocryptfs.diriv entries (no content yet).
2016-09-25reverse: rename types to reverseXYZJakob Unterwurzacher
...to prevent confusion with the forward variants. FS -> reverseFS file -> reverseFile Also add an incomplete read implementation.
2016-09-25reverse: add skeletonJakob Unterwurzacher
Compiles but does not do much else.
