[PATCH 12/12] netfilter: conntrack: use correct format characters

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

 



From: Bill Wendling <isanbard@xxxxxxxxx>

When compiling with -Wformat, clang emits the following warnings:

net/netfilter/nf_conntrack_helper.c:168:18: error: format string is not a string literal (potentially insecure) [-Werror,-Wformat-security]
                request_module(mod_name);
                               ^~~~~~~~

Use a string literal for the format string.
