bpf_progs - offload - fallback to stub on unpatched [4.14,5.4) kernels
Tested on a cuttlefish 5.4 device by varying program min/max kver
and injecting invalid bpf calls via:
// calling this should generate a program which will refuse to load
static void (*bpf_skb_invalid)(struct __sk_buff* skb) = (void*)(99999);
...(skb) {
bpf_skb_invalid(skb);
...
}
Test: builds, treehugger, see above
