## Name

skb_clone — duplicate an sk_buff

## Synopsis

`struct sk_buff * skb_clone (` | struct sk_buff * skb,
| gfp_t gfp_mask`)`;

## Arguments

`skb`

  buffer to clone

`gfp_mask`

  allocation priority

## Description

Duplicate an sk_buff. The new one is not owned by a socket. Both copies share the same packet data but not structure. The new buffer has a reference count of 1. If the allocation fails the function returns `NULL` otherwise the new buffer is returned.

If this function is called from an interrupt `gfp_mask` must be `GFP_ATOMIC`.
