Subject: [PATCH v1 net 0/5] ip: Fix warning in pskb_may_pull_reason() for tunnel devices.

syzkaller reported warnings in pskb_may_pull_reason(), which was
triggered by a VLAN packet sent over tunnel devices.

This series fixes the warning for sit, vti, vti6, ipip, and ip6tnl.


Kuniyuki Iwashima (5):
  sit: Pull header after checking skb->protocol in sit_tunnel_xmit().
  vti: Pull header after checking skb->protocol in vti_tunnel_xmit().
  ip6_vti: Pull header after checking skb->protocol in vti6_tnl_xmit().
  ipip: Pull header after checking skb->protocol in ipip_tunnel_xmit().
  ip6_tunnel: Pull header after checking skb->protocol in
    ip6_tnl_start_xmit().
