2019-01-01nametransform: Delete incomplete longname files on error.Sebastian Lackner
2018-09-23fusefrontend: get rid of os.File* wrappingJakob Unterwurzacher
Directly use int file descriptors for the dirfd and get rid of one level of indirection.

2017-11-25fusefrontend: Fix longname handling for renames with existing targetSebastian Lackner
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 <shortname> <longname>' This should actually work and replace the existing file, but instead it fails with: mv: cannot move '<shortname>' to '<longname>': 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.
2017-05-23nametransform: harden name decryption against invalid inputJakob Unterwurzacher
This fixes a few issues I have found reviewing the code: 1) Limit the amount of data ReadLongName() will read. Previously, you could send gocryptfs into out-of-memory by symlinking gocryptfs.diriv to /dev/zero. 2) Handle the empty input case in unPad16() by returning an error. Previously, it would panic with an out-of-bounds array read. It is unclear to me if this could actually be triggered. 3) Reject empty names after base64-decoding in DecryptName(). An empty name crashes emeCipher.Decrypt(). It is unclear to me if B64.DecodeString() can actually return a non-error empty result, but let's guard against it anyway.
2017-03-05nametransform: fix Raw64 not affecting symlink targetsJakob Unterwurzacher
The symlink functions incorrectly hardcoded the padded base64 variant.

HashLongName() incorrectly hardcoded the call to base64.URLEncoding.

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.
2016-07-03syscallcompat: OSX: add Unlinkat wrapperJakob Unterwurzacher
Also, replace remaining naked syscall.Openat calls.
2016-06-15Rename internal "toggledlog" package to "tlog"Jakob Unterwurzacher
tlog is used heavily everywhere and deserves a shorter name. Renamed using sed magic, without any manual rework: find * -type f -exec sed -i 's/toggledlog/tlog/g' {} +
2016-04-10longnames: fix fsstress failure, use dirfdJakob Unterwurzacher
Using dirfd-relative operations allows safe lockless handling of the ".name" files.
