Date: Thu, 6 Jul 2017 14:54:25 +0200 From: Pablo Neira Ayuso <pablo@...filter.org> To: netfilter-devel@...r.kernel.org Cc: davem@...emloft.net, netdev@...r.kernel.org Subject: [PATCH 2/2] netfilter: ebt_nflog: fix unexpected truncated packet From: Liping Zhang <zlpnobody@...il.com> "struct nf_loginfo li;" is a local variable, so we should set the flags to 0 explicitly, else, packets maybe truncated unexpectedly when copied to the userspace.
