Members

{unnamed_union}: anonymous
skc_refcnt: reference count
skc_hash: hash value used with various protocol lookup tables
skc_family: network address family
skc_state: Connection state
skc_reuse: SO_REUSEADDR setting
skc_reuseport: SO_REUSEPORT setting
skc_reuse: SO_REUSEADDR setting
skc_bound_dev_if: bound device index if != 0

skc_prot: protocol handlers inside a network family
skc_net: reference to the network namespace of this socket

Description

This is the minimal network layer representation of sockets, the header for struct sock and struct inet_timewait_sock.
