Hi all,
In fact, I really boot my build node after upgrade kernel.
I did some investigation
1. For below error:
In file included from
/home/xugang/tmp3/ovs-2.3/BUILD/openvswitch-2.3.0/_default/../datapath/linux/compat/include/net/gre.h:10:0,
from
/home/xugang/tmp3/ovs-2.3/BUILD/openvswitch-2.3.0/_default/datapath/linux/vport-gre.c:44:
include/net/gre.h: In function 'gre_handle_offloads':
include/net/gre.h:42:2: error: implicit declaration of function
'iptunnel_handle_offloads' [-Werror=implicit-f

^
include/net/gre.h:42:2: warning: return makes pointer from integer without
a cast [enabled by default]
cc1: some warnings being treated as errors
I checked method iptunnel_handle_offloads which declare it in
net/ip_tunnels.h
#ifdef CONFIG_INET
...
struct sk_buff *iptunnel_handle_offloads(struct sk_buff *skb, bool
gre_csum,
...
#endif /* CONFIG_INET */
I really can find its declaration in above head file.
But seemed CONFIG_INET not defined in kernel.
Then I go to /boot to check CONFIG_INET seemed already defined there
[root@vs260 boot]# grep CONFIG_INET config-3.10.0-123.8.1.el7.x86_64 |more
CONFIG_INET=y
CONFIG_INET_AH=m
CONFIG_INET_ESP=m
CONFIG_INET_IPCOMP=m
CONFIG_INET_XFRM_TUNNEL=m
CONFIG_INET_TUNNEL=m
CONFIG_INET_XFRM_MODE_TRANSPORT=m
CONFIG_INET_XFRM_MODE_TUNNEL=m
CONFIG_INET_XFRM_MODE_BEET=m
CONFIG_INET_LRO=y
CONFIG_INET_DIAG=m
CONFIG_INET_TCP_DIAG=m
CONFIG_INET_UDP_DIAG=m
CONFIG_INET6_AH=m
CONFIG_INET6_ESP=m
CONFIG_INET6_IPCOMP=m
CONFIG_INET6_XFRM_TUNNEL=m
CONFIG_INET6_TUNNEL=m
CONFIG_INET6_XFRM_MODE_TRANSPORT=m
CONFIG_INET6_XFRM_MODE_TUNNEL=m
CONFIG_INET6_XFRM_MODE_BEET=m
CONFIG_INET6_XFRM_MODE_ROUTEOPTIMIZATION=m
CONFIG_INET_DCCP_DIAG=m
So I want to know if when I build, some parameters needed ?

I checked our kernel which do not have static incline. Is that source
commit solved this problem?
3. What else info you need to help to debug?

Not sure about the specific steps you did, but I think you need to
bootstrap the tree (./boot) again to make the changes effective.
