Please apply commit 9990ddf47d41 ("net: tunnel: make skb_vlan_inet_prepare() return drop reasons") down to 6.1.y at least

[Salvatore Bonaccorso]

Hi stable maintainers,

9990ddf47d41 ("net: tunnel: make skb_vlan_inet_prepare() return drop
reasons") was alrady backported as well to 6.12.71 to address a
regression when backporting 81c734dae203 ("ip6_tunnel: use
skb_vlan_inet_prepare() in __ip6_tnl_rcv()") (this one was backported
without the prequisite commit to 6.12.67, 6.6.122, 6.1.162, 5.15.199
and 5.10.249).

Can you pick please as well 9990ddf47d41 for the other stable series
as needed? I can only give a confirmation that it works as exepcted
for the 6.1.y series as per https://bugs.debian.org/1127823#36 .

Regards,
Salvatore

it does not apply to any of those older kernels, which is probably why
it didn't get added there.  I tried to do the backport myself, but the
changes to drivers/net/vxlan/vxlan_core.c doesn't make sense to me, so I
can't do it, sorry.

Do you have a working backport anywhere?

thanks,

Hi Greg,

I'm sorry having wasted your time, I relayed the testing result, let
me loop in the user which tested the fix:

"Hostinger NOC" team, can you followup to the above? Can you provide a
working backport down to the 6.1.y series to Greg?

I've queued up backports for 6.6 and 6.1. If you need anything older, please
send a backport :)

Your backport to 6.1 can also be applied to 5.10 and 5.15.  I haven't
tested the result, but it does fix up all the places
skb_vlan_inet_prepare() is used on those branches.

Oh, but we don't even have enum skb_drop_reason in these branches, so
the result doesn't build (as you presumably already found).
