Subject: Re: [spp] [PATCH v3] spp_vf: fix initializing bug of forwarder
Date: Thu, 9 Aug 2018 13:25:40 +0900 [thread overview]

In-Reply-To: <201808090406.w7946BH0000646@imss03.silk.ntt-tx.co.jp>

> clear_forward_info() always initializes path[0] of g_forward_info[id].
> It is a bug and causes stopping forwarding accidentally if path[0] is
> referenced by spp_forward().
>
> This patch changes initializing as path[info->upd_index] instead of 0.
> It also includes following refactoring
> - using local vars to be simple
> - replace clear_forward_info() by memset
