[Bug 1672] New: bug egress hook virtio interface with VLAN
https://bugzilla.netfilter.org/show_bug.cgi?id=1672
Bug ID: 1672
Summary: bug egress hook virtio interface with VLAN
Product: nftables
Version: 1.0.x
Hardware: All
OS: other
Status: NEW
Severity: normal
Priority: P5
Component: kernel
Assignee: pablo at netfilter.org
Reporter: r.gabet at biche.org
Linux test 6.2.10-arch1-1 #1 SMP PREEMPT_DYNAMIC Fri, 07 Apr 2023 02:10:43
+0000 x86_64 GNU/Linux
nftables v1.0.7 (Old Doc Yak)
dhcpcd 9.4.1
isc-dhclient-4.4.3-P1
virtio interface : enp6s19
E1000 interface : enp6s20
I made tests with this ruleset :
table netdev filter {
chain egress {
type filter hook egress device "enp6s19.100" priority
filter;
policy accept;
meta nftrace set 1
log group 30
udp sport 68 udp dport 67 counter packets 0 bytes 0
}
chain egress2 {
type filter hook egress device "enp6s20.100" priority
filter;
policy accept;
meta nftrace set 1
log group 31
udp sport 68 udp dport 67 counter packets 0 bytes 0
}
}
With virtio, captured packet :
tcpdump: verbose output suppressed, use -v[v]... for full protocol decode
listening on nflog:30, link-type NFLOG (Linux netfilter log messages), snapshot
length 262144 bytes

If think the problem is related to incorrect @nh base, with virtio : oif
"enp6s19.100" @nh,0,320
0xe5050000401194a000000000ffffffff00440043013486f501010600f97b4c020000000000000000,
with E1000 @nh,0,48 0x450001482898 @th,0,160
0x4011510e00000000ffffffff004400430134
PS : I tried with dhcpcd and dhclient, I have the same issue.
