fuse_xattrs's Introduction

Abstract

This filesystem provides xattr support using sidecar files.

Latest version

The latest version and more information can be found on http://github.com/fbarriga/fuse_xattrs

How to mount a filesystem

Once fuse_xattrs is installed (see next section) running it is very simple:

fuse_xattrs source_directory mountpoint

To unmount the filesystem:

fusermount -u mountpoint

Distribution packages

Archlinux (https://aur.archlinux.org/packages/fuse_xattrs/):

yaourt -S fuse_xattrs

Building

First you need to download FUSE 2.9 or later from http://github.com/libfuse/libfuse.

mkdir build && cd build
cmake ..
make

Code Coverage

mkdir build && cd build
cmake -DENABLE_CODECOVERAGE=1 -DCMAKE_C_COMPILER=/usr/bin/gcc -DCMAKE_BUILD_TYPE=Debug ..
make

fuse_xattrs's Issues

Implement / fix symlinks

rr-@tornado:~/img$ touch a
touch: setting times of 'a': Function not implemented
rr-@tornado:~/img$ ln -s a b
ln: failed to create symbolic link 'b': Input/output error

File gets created, though:

rr-@tornado:~/img$ ls a b
a
b

But it doesn't function:

rr-@tornado:~/img$ echo asdasd>a
rr-@tornado:~/img$ cat b
rr-@tornado:~/img$

Implement touch

Trying to touch a file succeeds in terms of file creation, but then I get:

touch: setting times of 'img/a': Function not implemented

Since with the exception of xattr, this file system should behave like bindfs / passthrough, I think this function should get implemented.

This project is a godsend BTW. Shame SSHFS and NFS refuse to implement support for xattrs despite RFCs and patches flying around.

File ownership anomalies

First I create two test directories and bind one to another:

rr-@tornado:~$ mkdir a b
rr-@tornado:~$ fuse_xattrs -o allow_other a b

I create a file as my user:

rr-@tornado:~$ echo test >b/my_file

I create a file as root:

rr-@tornado:~$ sudo su
[sudo] password for rr-:
root@tornado:/home/rr-$ echo test2 >b/root_file
root@tornado:/home/rr-$

Let's examine ownership:

rr-@tornado:~$ la b
total 8
-rw-r--r-- 1 rr- rr- 5 Mar 16 21:13 my_file
-rw-r--r-- 1 rr- rr- 6 Mar 16 21:13 root_file

Both are owned by the user that mounted the directory.

If I repeat the steps in the source directory, I get expected ownership:

rr-@tornado:~$ cd a
rr-@tornado:~/a$ rm my_file root_file
rr-@tornado:~/a$ touch my_file
rr-@tornado:~/a$ sudo touch root_file
rr-@tornado:~/a$ la
total 0
-rw-r--r-- 1 rr-  rr-  0 Mar 16 21:17 my_file
-rw-r--r-- 1 root root 0 Mar 16 21:17 root_file
