From 99bdf88352fd8cad3d907a203d3720151d129c18 Mon Sep 17 00:00:00 2001 From: James Cowgill Date: Fri, 7 Apr 2017 12:10:26 +0100 Subject: [PATCH iptables] extensions: libxt_hashlimit: fix 64-bit printf formats hashlimit was using "%lu" in a lot of printf format specifiers to print 64-bit integers. This is incorrect on 32-bit architectures because "long int" is 32-bits there. On MIPS, it was causing iptables to segfault when printing these integers. Fix by using the correct format specifier.
