Hello,
I've got a simple socket filter program that seems to interrupt when
calling the load_word construct. I'm seeing the first message but never
the second one.
The code is the following
int SEC("filter") hashfilter(struct __sk_buff *skb) {
__u32 nhoff = BPF_LL_OFF + ETH_HLEN;
__u32 ip = 0;
__u32 *value = NULL;
#if 1
char fmtrei[] = "word load\n";
bpf_trace_printk(fmtrei, sizeof(fmtrei));
#endif
ip = load_word(skb, nhoff + offsetof(struct iphdr, saddr));
#if 1
char fmti[] = "work done\n";
bpf_trace_printk(fmti, sizeof(fmti));
#endif
In 4.18 and above this is not working but older kernel were ok.
Any suggestion will be appreciated.
Best regards,
