skb_scrub_packet — scrub an skb
void skb_scrub_packet ( | struct sk_buff * skb, |
bool xnet); |
skb_scrub_packet can be used after encapsulating or decapsulting a packet
into/from a tunnel. Some information have to be cleared during these
operations.
skb_scrub_packet can also be used to clean a skb before injecting it in
another namespace (xnet == true). We have to clear all information in the
skb that could impact namespace isolation.
