            Bug ID: 1412174
           Summary: Memory leak on mount/fuse when setxattr fails
           Product: GlusterFS
           Version: mainline
         Component: fuse
          Assignee: bugs at gluster.org
          Reporter: xhernandez at datalab.es
                CC: bugs at gluster.org



Description of problem:

When the setxattr fails for some extended attributes, fuse leaks memory.

This can happen if you try to set 'system.posix_acl_access' but gluster doesn't
have acl's enabled.

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


How reproducible:

Always

Steps to Reproduce:
1. gluster volume create test server:/brick
2. mount -t glusterfs server:/test /test
3. touch /test/file
4. for i in {1..100000}; do setfattr -n system.posix_acl_access -v "1"
/test/file; done

Actual results:

Doing a state dump, a leak of fuse_state_t structures is seen.

Expected results:

No leak should happen.

Additional info:

It seems that the state is not released after having been allocated if a pre-op
check fails.
