virfiletst: Test virFileIsSharedFS Introduce some basic test cases for virFileIsSharedFS(). More will be added later. In order to achieve desired result, mocks for setmntent() and statfs() need to be invented because the first thing that virFileIsSharedFS() does is calling the latter. If it finds a FUSE mount it'll call the former. The mock might look a bit complicated, but in fact it's quite simple. The test sets LIBVIRT_MTAB env variable to hold the absolute path to a file containing mount table. Then, statfs() returns matching FS it finds, and setmntent() is there just to replace /proc/mounts with the file the test wants to load. Adding this test also exposed a bug we have - because we assume the given path points to a file we cut off what we assume is a file name to obtain directory path and only then we call statfs(). This is buggy because the passed path could be already a mount point. Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Jiri Denemark <jdenemar@redhat.com>

virfile: Rework virFileIsSharedFixFUSE There are couple of things wrong with the current implementation. The first one is that in the first loop the code tries to build a list of fuse.glusterfs mount points. Well, since the strings are allocated in a temporary buffer and are not duplicated this results in wrong decision made later in the code. The second problem is that the code does not take into account subtree mounts. For instance, if there's a fuse.gluster mounted at /some/path and another FS mounted at /some/path/subdir the code would not recognize this subdir mount.
