[PATCH] netfilter: ip6t_SYNPROXY: unnecessary to check whether ip6_route_output returns NULL

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Liping Zhang <liping.zhang@xxxxxxxxxxxxxx>

ip6_route_output() will never return a NULL pointer, so there's no need
to check it.
