Add support for older kernels
Tested working properly back to 4.4
Disabled aliasing for kernels <4.15
Required, as these kernels do not have netdevice aliasing
Use the correct format specifier for (s)size_t
Resolves a compile-time warning on 32-bit
Check the return type of copy_from_user
Resolves a compile-time warning on ARM
Standardize kernel version checking
Requires icsscand >= v2.0.1
icsscand v2.0.0 will not work with older kernels, and would display an obscure error
In Linux 4.11.0, the vma argument was removed from the
vm_operations_struct::fault function.
In Linux 4.11.9, the netdevice destructor function was renamed to
priv_destructor and a needs_free_netdev member was added to the structure,
which should be set to true if the kernel module does not free its own struct
net_device upon exit.
