in kernel linux-2.6.16.60-0.54.5 code:
static int inet_create(struct socket *sock, int protocol){struct sock
*sk;struct inet_sock *inet;....
sk = sk_alloc(PF_INET, GFP_KERNEL, answer_prot, 1); if (sk == NULL)
goto out;
inet = inet_sk(sk);inet->is_icsk = (INET_PROTOSW_ICSK & answer_flags) ==
INET_PROTOSW_ICSK;
if (SOCK_RAW == sock->type) { inet->num = protocol;
if (IPPROTO_RAW == protocol) inet->hdrincl = 1; }
if (ipv4_config.no_pmtu_disc) inet->pmtudisc =
IP_PMTUDISC_DONT; else inet->pmtudisc = IP_PMTUDISC_WANT;
inet->id = 0;....}
my question is in the red line , why can convert like that?
thanks! _______________________________________________
