Subject: [PATCH] Add the missing function item of xtables to match
iptables 1.6
Message-ID: <1453888940-24244-1-git-send-email-wu.zh...@intel.com>
The struct of xtables_globals has been modified in iptables 1.6.
If connman runs with iptables 1.6, it can crash.
Program received signal SIGSEGV, Segmentation fault.
0x00000000 in ?? ()
0xb7dea89c in xtables_find_target () from /usr/lib/libxtables.so.11
0xb7deac1c in ?? () from /usr/lib/libxtables.so.11
0xb7dea793 in xtables_find_target () from /usr/lib/libxtables.so.11
The the missing function item of xtables is added to xtables_globals.
It can fix the above issue.
