2020-02-29fusefrontend: drop xattr user namespace restrictionJakob Unterwurzacher
We used to restrict setting xattrs to the "user." namespace. I don't see a real reason for this anymore, and it causes trouble for users who are using acls. Tests will be added in the next commit. https://github.com/rfjakob/gocryptfs/issues/453
2019-01-05fusefrontend: Allow to set/remove xattr on directory without read permission.Sebastian Lackner
Setting/removing extended attributes on directories was partially fixed with commit eff35e60b63331e3e10f921792baa10b236a721d. However, on most file systems it is also possible to do these operations without read access (see tests). Since we cannot open a write-access fd to a directory, we have to use the /proc/self/fd trick (already used for ListXAttr) for the other operations aswell. For simplicity, let's separate the Linux and Darwin code again (basically revert commit f320b76fd189a363a34bffe981aa67ab97df3362), and always use the /proc/self/fd trick on Linux. On Darwin we use the best-effort approach with openBackingFile() as a fallback. More discussion about the available options is available in https://github.com/rfjakob/gocryptfs/issues/308.
2019-01-02fusefrontend: use Fsetxattr/Fgetxattr/etc on all platformsJakob Unterwurzacher
Darwin now also has these functions, use them. Simplifies the code and makes it symlink-safe on Darwin as well.
2019-01-01fusefrontend: only compile getBackingPath() on DarwinJakob Unterwurzacher
This function is NOT symlink-safe. Darwin needs it because it lacks fgetxattr(2) and friends.
2019-01-01fusefrontend: make ListXAttr symlink-safe on LinuxJakob Unterwurzacher
Uses /proc/self/fd.
2019-01-01fusefrontend: make RemoveXAttr() symlink-safeJakob Unterwurzacher
Uses /proc/self/fd on Linux.
2019-01-01fusefrontend: make SetXAttr() symlink-safe on LinuxJakob Unterwurzacher
Uses the /proc/self/fd trick.
2019-01-01fusefrontend: make GetXAttr() symlink-safe on LinuxJakob Unterwurzacher
Uses the /proc/self/fd trick, which does not work on Darwin.
2018-05-07xattr: added passing of a "flags" parameterBolshevik
Pass the "flags" parameter to the lower layer syscall. This makes Apple applications being able to successfully save data.
