Subject: extensions: format-security fixes in libip[6]t_icmp
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
commit 61d6c3834de3 ("xtables: add 'printf' attribute to xlate_add")
introduced support for gcc feature to check format string against passed
argument. This commit adds missing bits to extenstions's libipt_icmp.c
and libip6t_icmp6.c that were causing build to fail.
Fixes: 61d6c3834de3 ("xtables: add 'printf' attribute to xlate_add")
