[ Upstream commit 03702d4d29be4e2510ec80b248dbbde4e57030d9 ]
Since commit 58e0be1ef6118 ("net: use struct_group to copy ip/ipv6
header addresses"), ip and ipv6 headers started to use the __struct_group
definition, which is defined at include/uapi/linux/stddef.h. However,
linux/stddef.h isn't explicitly included in include/uapi/linux/{ip,ipv6}.h,
which breaks build of xskxceiver bpf selftest if you install the uapi
headers in the system:
$ make V=1 xskxceiver -C tools/testing/selftests/bpf
...
make: Entering directory '(...)/tools/testing/selftests/bpf'
gcc -g -O0 -rdynamic -Wall -Werror (...)
In file included from xskxceiver.c:79:
/usr/include/linux/ip.h:103:9: error: expected specifier-qualifier-list before ‘__struct_group’
103 | __struct_group(/* no tag */, addrs, /* no attrs */,
| ^~~~~~~~~~~~~~
...
Include the missing <linux/stddef.h> dependency in ip.h and do the
same for the ipv6.h header.
