Update 0002 patch to match the one sent as a pull request. The previous
one introduced a new problem that has been addressed in the new version.
Some Linux headers included in certain toolchains may not have an
updated linux/if_tunnel.h which includes linux/ip.h, so we need to
include it unconditionally otherwise linux/if_tunnel.h will use the
struct iphdr before being defined and the compilation will fail in this
way:
In file included from iptunnel.c:33:0:
/usr/include/linux/if_tunnel.h:37:16: error: field 'iph' has incomplete
type
struct iphdr iph;

Subject: [PATCH] iptunnel.c: do not include netinet/ip.h
|
|
|
|
This fixes a struct redefinition problem like this one:
|
|
|
|
================================
|
|
In file included from /usr/include/linux/if_tunnel.h:6:0,
|
|
from iptunnel.c:34:
|
|
/usr/include/linux/ip.h:85:8: error: redefinition of 'struct iphdr'
|
|
struct iphdr {
|
|
^
|
|
In file included from iptunnel.c:29:0:
|
|
/usr/include/netinet/ip.h:45:8: note: originally defined here
|
|
struct iphdr
|
|
^
|
|
================================
|
|
|
|
iptunnel.c includes netinet/ip.h which contains a definition of the
|
|
iphdr struct.
|
|
|
|
iptunnel.c also includes linux/if_tunnel.h which includes linux/ip.h
|
|
which contains a definition of the iphdr struct.
|
|
|
|
So, both netinet/ip.h and linux/ip.h define the iphdr struct, and both
|
|
of them have been included directly or indirectly by iptunnel.c. Because
|
|
of that the compilation fails due to a struct redefinition.
|
|
|
|
The problem can be solved by just not including netinet/ip.h.
|
|
|
|
However, some Linux headers included in certain toolchains may not have
|
|
an updated linux/if_tunnel.h which includes linux/ip.h, so we need to
|
|
include it unconditionally otherwise linux/if_tunnel.h will use the
|
|
struct iphdr before being defined and the compilation will also fail in
|
|
this way:
|
|

In file included from iptunnel.c:33:0:
|
|
/usr/include/linux/if_tunnel.h:37:16: error: field 'iph' has incomplete type
|
|
struct iphdr iph;
