From 4a5a5c73b7cfee46a0b1411903cfa0dea532deec Mon Sep 17 00:00:00 2001 From: Jan Engelhardt Date: Fri, 19 Mar 2010 17:32:59 +0100 Subject: netfilter: xtables: slightly better error reporting When extended status codes are available, such as ENOMEM on failed allocations, or subsequent functions (e.g. nf_ct_get_l3proto), passing them up to userspace seems like a good idea compared to just always EINVAL.
