Hi All!
Seems there is a regression of SRv6 End.DT6 function in VRF mode. In the following scenario packet is decapsulated successfully on vrf10 interface but not forwarded to vrf10's slave interface:
ip netns exec r4 ip -6 nexthop add id 1004 encap seg6local action End.DT6 vrftable 10 dev vrf10
ip netns exec r4 ip -6 route add fcff:0:4:200:: nhid 1004
In End.DT6 legacy mode everything works good:
ip netns exec r4 ip -6 nexthop add id 1004 encap seg6local action End.DT6 table 10 dev vrf10
ip netns exec r4 ip -6 route add fcff:0:4:200:: nhid 1004
The issue impacts even stable v5.18.1. Please help to fix it.
Thanks!
Anton

@Andrea: when you fix a reported issue, next time please include a "Link: <url>" that links to the report, as explained in the documentation (see submitting-patches.rst). Linus wants these tags(¹) and my regression tracking efforts rely on them (that'S why I had to write this mail to tell regression tracking bot with above command that the issue has been fixed). tia!
Ciao, Thorsten
