Functions like ipgreheader(), ip6greheader(),all use netdevpriv(dev) to access their device-specific private data. When called with the bond device, netdevpriv() returns the bond's private data (struct bonding) instead of the expected type (e.g. struct iptunnel), leading to garbage values being read and kernel crashes. Fix this by introducing bondheaderops with wrapper functions that delegate to the active slave's headerops using the slave's own device. This ensures netdevpriv() in the slave's header functions always receives the correct device. The fix is placed in the bonding driver rather than individual device drivers, as the root cause is bond blindly inheriting headerops from the slave without considering that these callbacks expect a specific netdevpriv() layout. The type confusion can be observed by adding a printk in ipgreheader() and running the following commands: ip link add dummy0 type dummy ip addr add 10.0.0.1/24 dev dummy0 ip link set dummy0 up ip link add gre1 type gre local 10.0.0.1 ip link add bond1 type bond mode active-backup ip link set gre1 master bond1 ip link set gre1 up ip link set bond1 up ip addr add fe80::1/64 dev bond1
