I can confirm this behaviour upgrading from 1.6.1 to 1.7.0 on nixos.

Note: We reboot the server in question every day, and if the unit comes up during boot (systemd with After=network.target) it does NOT display this error (three days in a row so far). However, if the unit is restarted the error starts to appear immediately.

The "rtnetlink NeighMessage has a wrong attribute data length" error comes from the github.com/jsimonetti/rtnetlink package that the collector uses to fetch the ARP cache via rtnetlink.

    // errInvalidNeighMessageAttr is returned when neigh attributes are malformed.
    errInvalidNeighMessageAttr = errors.New("rtnetlink NeighMessage has a wrong attribute data length")

There are only two places in that code which can produce such an error:

func (a *NeighAttributes) decode(ad *netlink.AttributeDecoder) error {
    for ad.Next() {
        switch ad.Type() {
        case unix.NDA_UNSPEC:
            // unused attribute
        case unix.NDA_DST:
            l := len(ad.Bytes())
            if l != 4 && l != 16 {
                return errInvalidNeighMessageAttr
            }
            a.Address = ad.Bytes()
        case unix.NDA_LLADDR:
            // Allow IEEE 802 MAC-48, EUI-48, EUI-64, or 20-octet
            // IP over InfiniBand link-layer addresses
            l := len(ad.Bytes())
            if l != 6 && l != 8 && l != 20 {
                return errInvalidNeighMessageAttr
            }
            a.LLAddress = ad.Bytes()
...

This implies that you have neighbor cache entries of type NDA_DST or NDA_LLADR, which are an unexpected length.

Are you able to paste the contents of your neighbor cache, using the command ip neigh show?

@jpds Thanks, that doesn't look anything unusual.
I'm not able to reproduce this issue, and sorta scratching my head about what could lead to a NDA_DST / NDS_LLADR entry with a length not supported by jsimonetti/rtnetlink. Can you perhaps elaborate a bit on your network setup?

This isn't really a bug in node_exporter per se, and probably needs some input from the rtnetlink package authors (@jsimonetti help...?)

As a workaround, you can revert to the /proc/net/arp parsing method (used by node_exporter < 1.7.0) with --no-collector.arp.netlink, but beware that it does not support IPoIB environments (which was the main reason to migrate to using rtnetlink).

[jpds]

Can you perhaps elaborate a bit on your network setup?

I guess the only thing "special" about my particular setup is that I'm using networkd on NixOS.

With the workaround flag, the collector succeeds:

node_scrape_collector_success{collector="arp"} 1

These neighbors' LLADDR are clearly each 6 bytes, and the DST is either 4 or 16 byte, so should not cause this issue. I wonder if iproute2 fiters out some 'unknown' entries and just silenty drop it.

I'd be curious to see what is returned if those size constraints are loosenend. Would that be something you could test in your setup? I can see if I can easily send you a nix derivation that includes a patch.

[jsimonetti]

Additionally, the output of strace -ff -erecvmsg ip neigh show might shed some light aswel.

Sure.

Same problem here with seemingly even simpler networking setup. Arch with systemd-networkd and kernel 6.6.2-arch1-1:

# ip neigh
172.31.1.1 dev ens3 lladdr d2:74:7f:6e:37:e3 REACHABLE
fe80::1 dev ens3 lladdr d2:74:7f:6e:37:e3 router REACHABLE

strace shows some interesting results:

# strace -ff -erecvmsg ip neigh show 2>&1 | grep -o -E "nla_len=.{,3}, nla_type=NDA_LLADDR"
nla_len=10, nla_type=NDA_LLADDR
nla_len=10, nla_type=NDA_LLADDR
nla_len=10, nla_type=NDA_LLADDR
nla_len=10, nla_type=NDA_LLADDR
nla_len=4, nla_type=NDA_LLADDR
nla_len=10, nla_type=NDA_LLADDR
nla_len=10, nla_type=NDA_LLADDR
nla_len=10, nla_type=NDA_LLADDR

# strace -ff -erecvmsg ip neigh show 2>&1 | grep -o -E "nla_len=.{,3}, nla_type=NDA_DST"
nla_len=8, nla_type=NDA_DST
nla_len=8, nla_type=NDA_DST
nla_len=8, nla_type=NDA_DST
nla_len=8, nla_type=NDA_DST
nla_len=8, nla_type=NDA_DST
nla_len=20, nla_type=NDA_DST
nla_len=20, nla_type=NDA_DST
nla_len=20, nla_type=NDA_DST
nla_len=20, nla_type=NDA_DST
nla_len=20, nla_type=NDA_DST
nla_len=20, nla_type=NDA_DST
nla_len=20, nla_type=NDA_DST

Does not seem like the values the go library expects at all, however I don't know what nla_len is exactly and if that is different than the number of bytes the go lib expects. It seems like nla_len is always 4 greater than the payload. So I'm guessing the problem is the empty LLADDR reported for the "0.0.0.0" destination:

[[{nla_len=8, nla_type=NDA_DST}, inet_addr("0.0.0.0")], {nla_len=4, nla_type=NDA_LLADDR}, [{nla_len=8, nla_type=NDA_PROBES}, 0], [{nla_len=20, nla_type=NDA_CACHEINFO}, {ndm_confirmed=386074, ndm_used=380074, ndm_updated=380074, ndm_refcnt=0}]]

edit: this last line also appears in the dump from @jpds

You could be on to something here. Let me see if I can make a reproducer.

WRT nla_len that is the attribute length including the length and type field, which are each 2 bytes, so it is to be expected that it is always 4 more than the data size.

FWIW, I tried to prove a suspicion that it is related to network namespaces, but alas that proved fruitless. node_exporter works as expected, even when running in a non-global netns.

This looks like it is the issue currently. It appears iproute2 silently ignores this entry.

I think the correct course of action would be to allow zero-length NDA_LLADDR attributes on a neighbor entry, as clearly the kernel thinks it's OK. This could have some effects to consumers of the module, as they would now have to manually filter out these entries.
