mount.cifs: check for invalid characters in device name and mountpoint
It's apparently possible to corrupt the mtab if you pass embedded newlines to addmntent. Apparently tabs are also a problem with certain earlier glibc versions. Backslashes are also a minor issue apparently, but we can't reasonably filter those. Make sure that neither the devname or mountpoint contain any problematic characters before allowing the mount to proceed. Signed-off-by: Jeff Layton <jlayton@redhat.com>
