Merge branch 'vlan-ensure-sufficient-headroom-in-vlan_dev_hard_header'
Eric Dumazet says:
====================
vlan: ensure sufficient headroom in vlan_dev_hard_header()
Callers that only reserve ETH_HLEN or less, or skbs allocated before
dynamic device/headroom changes (such as toggling VLAN_FLAG_REORDER_HDR
or bonding/team switching slaves), can reach vlan_dev_hard_header() with
insufficient headroom and trigger skb_under_panic().
When vlan_dev_hard_header() returns -ENOMEM upon skb_cow_head() failure,
a few callers of dev_hard_header() / llc_mac_hdr_init() had pre-existing
error-handling bugs:
