Command to display skb_clone_sk manual in Linux: $ man 9 skb_clone_sk

NAME

skb_clone_sk - create clone of skb, and take reference to socket

SYNOPSIS

struct sk_buff * skb_clone_sk(struct sk_buff * skb);

ARGUMENTS

skb

: the skb to clone

DESCRIPTION

This function creates a clone of a buffer that holds a reference on sk_refcnt. Buffers created via this function are meant to be returned using sock_queue_err_skb, or free via kfree_skb.

When passing buffers allocated with this function to sock_queue_err_skb it is necessary to wrap the call with sock_hold/sock_put in order to prevent the socket from being released prior to being enqueued on the sk_error_queue.
