Created attachment 633940 [details]
patch against fuse fedpkg repo to add upstream patch

Description of problem:

We use sshfs mounted home directories, and we were finding that sshfs would mysteriously crash.  Examining the core dump revealed that there was a missing pointer dereference in a free along an error path in the fuse library.

When I went to submit an upstream bug, it turned out that it had already been fixed

http://fuse.git.sourceforge.net/git/gitweb.cgi?p=fuse/fuse;a=commit;h=3c4c063a2fd5cc6e9ce2b5db82e2a0dfa59b2e40

Could we please get this patch included in the current release.

Version-Release number of selected component (if applicable):

All fuse release prior to 2.9.1.

How reproducible:

Always.

Steps to Reproduce:
1. Mount home directory with sshfs.
2. Start gnome desktop on mounted home directory
3. May have to repeat a couple of times.
  
Actual results:

The sshfs program dies and you get a "transport endpoint is not connected" error message when trying to access your home directory.

Expected results:

You expect to be able to access your home directory.

Additional info:

I've attached a patch against the f17 branch in the Fedora fedpkg repo for fuse to add a back ported version of the upstream patch.
