fusefrontend: Improve documentation of mkdirWithIv and WriteDirIV

2017-12-01T08:41:52+00:00

As requested in https://github.com/rfjakob/gocryptfs/pull/179

syscallcompat: check that we get NOFOLLOW wherever possible

2017-11-30T18:40:53+00:00

...and fix the instances where the AT_SYMLINK_NOFOLLOW / O_NOFOLLOW / O_EXCL flag was missing.

fusefrontend: allow_other: close race between mkdir and chown

2017-11-29T12:28:04+00:00

Fixes the same problem as described in 72b975867a3b9bdf53fc2da62e2ba4a328d7e4ab, except for directories instead of device nodes.

syscallcompat: Introduce unlinkat syscall with flags argument

2017-11-29T11:41:23+00:00

fusefrontend: Fix longname handling for renames with existing target

2017-11-25T15:19:09+00:00

Fixes https://github.com/rfjakob/gocryptfs/issues/170 Steps to reproduce the problem: * Create a regular forward mount point * Create a file with a shortname and one with a long filename * Try to run 'mv ' This should actually work and replace the existing file, but instead it fails with: mv: cannot move '' to '': File exists The problem is the creation of the .name file. If the target already exists we can safely ignore the EEXIST error and just keep the existing .name file.

nametransform: Return error if decrypted name is '.' or '..'

2017-11-22T22:42:08+00:00

dirivcache: add better function comments + a sanity check on Store()

2017-09-03T11:53:50+00:00

The comments were unclear on whether relative or absolute paths have to be passed.

nametransform: extend diriv cache to 100 entries

2017-08-09T20:00:53+00:00

* extend the diriv cache to 100 entries * add special handling for the immutable root diriv The better cache allows to shed some complexity from the path encryption logic (parent-of-parent check). Mitigates https://github.com/rfjakob/gocryptfs/issues/127

nametransform: add Dir() function

2017-08-06T21:14:39+00:00

Dir is like filepath.Dir but returns "" instead of ".". This was already implemented in fusefrontend_reverse as saneDir(). We will need it in nametransform for the improved diriv caching.

nametransform: move diriv cache into it's own package

2017-08-06T19:59:15+00:00

Needs some space to grow. renamed: internal/nametransform/diriv_cache.go -> internal/nametransform/dirivcache/dirivcache.go
