Subject: [PATCH] added ipv6_dst_lookup_flow define for VZ7 kernels
Date: Thu, 4 Mar 2021 19:30:18 +0100 [thread overview]
Message-ID: <20210304183018.42658-1-b.braunger@syseleven.de> (raw)
This patch adds an additional check for OpenVZ / Virtuozzo 7 custom
kernels to ensure ipv6_dst_lookup_flow is defined.
It also splits the very long version checking into multiple lines for
better reading.

Since the error mentioned in "Wireguard DKMS build on OpenVZ 7" still
occures, I searched for a way to check if the module is compiled on
a VZ kernel. This patch works for me, I tested on Virtuozzo 7 and
plain CentOS 7. Can compile on both without error and the module is
loadable.
Probably Virtuozzo will backuport ipv6_dst_lookup_flow some day but
they can't (or don't want to) tell me when.
If so one can compare VZVERSION to the current one to ensure the definition
for older verions.
