Subject: IPv6 traffic distribution problem with OVS group on 6.5
Date: Wed, 13 Sep 2023 06:54:07 +0000 [thread overview]
Message-ID: <20230913065407.GA510095@bm02> (raw)
Hi,
We found that OVS group always selected the same bucket for different L4
flows between two given IPv6 addresses on 6.5. It was because commit
e069ba07e6c7 ("net: openvswitch: add support for l4 symmetric hashing")
introduced support for symmetric hashing and used the flow dissector,
which had a problem that it didn't incorporate transport ports when
flow label is present in IPv6 header. The bug is fixed by this commit:
a5e2151ff9d5 ("net/ipv6: SKB symmetric hash should incorporate transport ports")
Could you please backport it to 6.5.y?
Issue: https://github.com/antrea-io/antrea/issues/5457
Thanks,
Quan
