[lwip-devel] Sockets: select_waiting overflow

[Joan Lledó]

Hello,

I'm having an overflow in my select_waiting due to a bug, and the
assertion "sock->select_waiting > 0" is failing and aborting the
stack.

Would it not be better to use LWIP_ERROR instead of LWIP_ASSERT?, to
allow the user to return gracefully with a proper errno. The current
assertion could be used in a DoS attack to abort the stack from a
client.

What do you think?
