AST-2018-006: Properly handle WebSocket frames with 0 length payload. · 64361379

Sean Bright authored 7 years ago

In ast_websocket_read() we were not adequately checking that the
payload_len was non-zero before passing it to ws_safe_read(). Calling
ws_safe_read with a len argument of 0 will result in a busy loop until
the underlying socket is closed.
