[sshfs] sshfs mount with mount point in $PATH

[Joachim K. <jk...@mp...>]

Hi,

(apologies if this is already a known issue, I couldn't find it anywhere.)

I recently encountered the following problem with sshfs (not sure if
it's an sshfs issue or applies to fuse in general): When I try to create
an sshfs mount to a mount point that is in my $PATH variable, sshfs
hangs and the system as a whole is partially blocked. For instance, even
simple commands like "ls" will hang afterwards when asked to access the
intended mount point or its parent directory. Killing all user processes
does not solve the problem, I had to reboot the machine.

Steps to reproduce (using bash syntax):

  export PATH=$HOME/mountpoint/whatever:$PATH
  sshfs us...@ho...: $HOME/mountpoint

where, of course, $HOME/mountpoint should be an empty directory.

My sshfs and fuse versions are

SSHFS version 2.3
FUSE library version: 2.8.6
fusermount version: 2.8.6
using FUSE kernel interface version 7.12

The system is Kubuntu 12.04 with the x86_64 version of kernel
3.2.0-32-generic. I can reproduce the problem on both my Laptop and
desktop PCs, both of which run the same system, kernel, fuse and sshfs
versions.

Cheers,
Joachim
