in lwip_accept (in sockets.c) there is this code:
memset(&sin, 0, sizeof(sin));
sin.sin_len = sizeof(sin);
sin.sin_family = AF_INET;
sin.sin_port = htons(port);
sin.sin_addr.s_addr = naddr.addr;
if (*addrlen > sizeof(sin))
*addrlen = sizeof(sin);
SMEMCPY(addr, &sin, *addrlen);
When addrlen and or addr are NULL, this code crashes. Most BSD and
linux implementations allow it to be NULL. Could/should we change
this code to be enclosed in:
if (addr != NULL)
{
...
}
Thoughts?
