2017-05-30fusefrontend_reverse: move pathiv to its own packageJakob Unterwurzacher
We will also need it in forward mode.
2017-04-01fusefrontend_reverse: add comment to newVirtualFileJakob Unterwurzacher
...and improve and comment variable naming in findLongnameParent. No semantic changes.
2017-03-28fusefrontend_reverse: consistent file owners for .diriv, .name filesdanim7
This PR addresses the Issue #95, about "Confusing file owner for longname files in reverse mode". It affects only the reverse mode, and introduces two modifications: 1) The "gocryptfs.longname.XXXX.name" files are assigned the owner and group of the underlying plaintext file. Therefore it is consistent with the file "gocryptfs.longname.XXXX" that has the encrypted contents of the plaintext file. 2) The two virtual files mentioned above are given -r--r--r-- permissions. This is consistent with the behavior described in function Access in internal/fusefrontend_reverse/rfs.go where all virtual files are always readable. Behavior also observed in point c) in #95 .

2017-03-05nametransform: fix Raw64 not affecting longnamesJakob Unterwurzacher
HashLongName() incorrectly hardcoded the call to base64.URLEncoding.
2016-12-10Replace all calls to naked panic() with log.Panic()Jakob Unterwurzacher
We want all panics to show up in the syslog.
2016-11-10reverse: 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
2016-10-05reverse: initialize the longname cache only when reverse mode is usedJakob Unterwurzacher
Gets rid of the idling longnameCacheCleaner thread in "normal" mode.

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.
2016-09-25Implement changes proposed by gosimple.Jakob Unterwurzacher
Also delete the unused "dirIVNameStruct", found by deadcode.
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.
