commit 61d6c3834de3 ("xtables: add 'printf' attribute to xlate_add")
|
|
|
8cce6c |
introduced support for gcc feature to check format string against passed
|
|
|
8cce6c |
argument. This commit adds missing bits to extenstions's libipt_icmp.c
|
|
|
8cce6c |
and libip6t_icmp6.c that were causing build to fail.
