Hi all, I am trying to update kernel module that used to run for kernel version < 4.4.0. I found out that struct nf_hook_ops and the signature for function type nf_hookfn have changed for kernels higher than version 4.4.0. However, I couldn't find any documentation that explains the change. To be precise for kernel 4.1.0 (http://lxr.free-electrons.com/source/include/linux/netfilter.h?v=4.1), 77 typedef unsigned int nf_hookfn(const struct nf_hook_ops *ops, 78 struct sk_buff *skb, 79 const struct nf_hook_state *state); 80 81 struct nf_hook_ops { 82 struct list_head list; 83 84 /* User fills in from here down. */ 85 nf_hookfn *hook; 86 struct module *owner; 87 void *priv; 88 u_int8_t pf; 89 unsigned int hooknum; 90 /* Hooks are ordered in ascending priority. */ 91 int priority; 92 }; for kernel 4.4.0 (http://lxr.free-electrons.com/source/include/linux/netfilter.h?v=4.4), 83 typedef unsigned int nf_hookfn(void *priv, 84 struct sk_buff *skb, 85 const struct nf_hook_state *state); 86 87 struct nf_hook_ops { 88 struct list_head list; 89 90 /* User fills in from here down. */ 91 nf_hookfn *hook; 92 struct net_device *dev; 93 void *priv; 94 u_int8_t pf; 95 unsigned int hooknum; 96 /* Hooks are ordered in ascending priority. */ 97 int priority; 98 }; As you can see, the first parameter of nf_hookfn() is changed from const struct nf_hook_ops *ops to void *priv and struct nf_hook_ops no longer has the member for struct module *owner; and instead has the member of struct net_device *dev; If anyone can tell me how to cope with this changes, it will be very helpful. Thanks!
