Description

Hi

I followed https://suricata.readthedocs.io/en/latest/capture-hardware/ebpf-xdp.html to run suricata with xdp_filter, it appears when there are existing flows in map flow_table_v4, starting suricata would result segmenation fault.

# bpftool map list id 9
9: percpu_hash  name flow_table_v4  flags 0x0
    key 16B  value 16B  max_entries 32768  memlock 19660800B

# bpftool map dump id 9 | tail -36

I am still new to suricata, How do I test in IDS mode? just change the copy-mode to ids?

I tested in xdp-mode soft and in IPS mode, still same issue.

since the values_array = 0x0 from the stack trace, it appears the bpf_map_lookup_elem below did not populate values_array in src/util-ebpf.c


824         BPF_DECLARE_PERCPU(struct pair, values_array, tcfg->cpus_count);
 825         memset(values_array, 0, sizeof(values_array));
 826         int res = bpf_map_lookup_elem(mapfd, &next_key, values_array);
 827         if (res < 0) {
 828             SCLogDebug("no entry in v4 table for %d -> %d", key.port16[0], key.port16[1]);
 829             key = next_key;
 830             continue;
 831         }
 832         for (i = 0; i < tcfg->cpus_count; i++) {
 833             /* let's start accumulating value so we can compute the counters */
 834             SCLogDebug("%d: Adding pkts %lu bytes %lu", i,
 835                        BPF_PERCPU(values_array, i).packets,
 836                        BPF_PERCPU(values_array, i).bytes);
 837             pkts_cnt += BPF_PERCPU(values_array, i).packets;
 838             bytes_cnt += BPF_PERCPU(values_array, i).bytes;
 839         }

and the bpf_map_lookup_elem appears coming from ebpf/bpf_helpers.h


static void *(*bpf_map_lookup_elem)(void *map, void *key) =
        (void *) BPF_FUNC_map_lookup_elem;

I also noticed there is bpf_map_lookup_elem in libbpf src/bpf.c


int bpf_map_lookup_elem(int fd, const void *key, void *value)
{
        union bpf_attr attr;

        memset(&attr, 0, sizeof(attr));
        attr.map_fd = fd;
        attr.key = ptr_to_u64(key);
        attr.value = ptr_to_u64(value);

        return sys_bpf(BPF_MAP_LOOKUP_ELEM, &attr, sizeof(attr));
}

are the bpf_map_lookup_elem in bpf_helpers.h and libbpf src/bpf.c same ? if not same which one is called?

probably I did not make it clear, the condition to reproduce the issue is:

1, af-packet IPS mode
2, bypass is set to true in af-packet mode
3, xdp_filter attached
4, generate traffic by iperf3 to pass through suricata to create bypassed flows in flow_table_v4 map
5, restart suricata with above 4 conditions

so IDS mode will not apply here

I try to reproduce that and failed (using git from 2020/12/27).
