Name:TCP listen path runs lockless.* We forced "struct sock" to be const qualified to make sure* we don't modify one of its field by mistake.* Here, we increment sk_drops which is an atomic_t, so we can safely* make sock writable again.

Proto:static inline void tcp_listendrop(const struct sock *sk)

Type:void

Parameter:

TypeParameterName
const struct sock *sk
2130  atomic_inc( & sk_drops)
2131  __NET_INC_STATS(sock_net(sk), LINUX_MIB_LISTENDROPS)
