[sshfs] Symlinks point to wrong path with SFTP server

[Adam N. <a.n...@sh...>]

Hi all,

When I mount an SFTP share using sshfs, I am unable to create symlinks
properly:

  $ ln -s ./test ./test2
  $ ls test2
  lrwxrwxrwx 1 root webusers   11 Jul  3 09:11 test2 -> /test

Here the link points to the root directory when it should point to the
current directory.

If I add the transform_symlinks option it still doesn't work:

  $ ln -s ./test ./test2
  $ ls test2
  lrwxrwxrwx 1 root webusers   11 Jul  3 09:13 test2 -> ../../../test

Here it points to the root of the SFTP share even though it should
point to the current directory.

Connecting with the command-line sftp client and creating the symlink
there works, when transform_symlinks is set:

  sftp> symlink test test2
  ...
  $ ls test2
  lrwxrwxrwx 1 root webusers   11 Jul  3 09:13 test2 -> test

So it looks like sshfs is not creating symlinks correctly.

Oddly enough if I mount a folder over SSH (rather than SFTP) then
symlinks are created perfectly well.  It only seems to break over SFTP.

Has anyone else experienced this problem?  Are there any other options
I can try?  I'm running SSHFS v2.4.

Many thanks,
Adam.
