Dmitry Antipov ebc5c63045 ppp: reject claimed-as-LCP but actually malformed packets ... [ Upstream commit f2aeb7306a898e1cbd03963d376f4b6656ca2b55 ] Since 'ppp_async_encode()' assumes valid LCP packets (with code from 1 to 7 inclusive), add 'ppp_check_packet()' to ensure that LCP packet has an actual body beyond PPP_LCP header bytes, and reject claimed-as-LCP but actually malformed data otherwise.
