Date: Mon, 18 May 2015 18:25:10 +0200 From: Pablo Neira Ayuso <pablo@...filter.org> To: netfilter-devel@...r.kernel.org Cc: davem@...emloft.net, netdev@...r.kernel.org Subject: [PATCH 07/21] netfilter: ipset: Return ipset error instead of bool From: Sergey Popovich <popovich_sergei@...l.ua> Statement ret = func1() || func2() returns 0 when both func1() and func2() return 0, or 1 if func1() or func2() returns non-zero. However in our case func1() and func2() returns error code on failure, so it seems good to propagate such error codes, rather than returning 1 in case of failure.
