[RFC PATCH-for-5.2 0/2] net: Do not accept packets with invalid huge size

[Philippe Mathieu-Daudé]

Hi,

This is a simple attempt to avoid the following pattern:

  ssize_t pkt_size = get_pkt_size(); // returns errno

  // no check

  send_packet(size_t size=pkt_size); // size casted to unsigned
                                     // -> overflow

Regards,

Phil.
