lockd: Plug nlm_file refcount leak on cached nlm_do_fopen() failure
In the Linux kernel, the following vulnerability has been resolved: lockd: Plug nlm_file refcount leak on cached nlm_do_fopen() failure The cached-file path in nlm_lookup_file() reaches the found: label unconditionally, even when nlm_do_fopen() fails. At that label *result and file->f_count are updated before the error is returned. The wrappers nlm3svc_lookup_file() and nlm4svc_lookup_file() then bail out of their switch without copying *result back to their caller, so the proc handler's local nlm_file pointer remains NULL and the cleanup path skips nlm_release_file(). The f_count increment is never released, and nlm_traverse_files() can no longer reap the file because its refcount never returns to zero between requests. Short-circuit the cached path so neither *result nor f_count is touched when nlm_do_fopen() fails on a hashed nlm_file.
