# skb\_clone\_sk(9)

create clone of skb, and take reference to socket

## 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.
