Message-Id: <1424409867-23041-1-git-send-email-al.drozdov@gmail.com> Date: Fri, 20 Feb 2015 08:24:27 +0300 From: Alexander Drozdov <al.drozdov@...il.com> To: "David S. Miller" <davem@...emloft.net>, Daniel Borkmann <dborkman@...hat.com>, Eric Dumazet <edumazet@...gle.com>, Al Viro <viro@...iv.linux.org.uk>, Willem de Bruijn <willemb@...gle.com>, "Michael S. Tsirkin" <mst@...hat.com> Cc: netdev@...r.kernel.org, linux-kernel@...r.kernel.org, Alexander Drozdov <al.drozdov@...il.com> Subject: [PATCH] af_packet: allow packets defragmentation not only for hash fanout type Packets defragmentation was introduced for PACKET_FANOUT_HASH only, see 7736d33f4262 ("packet: Add pre-defragmentation support for ipv4 fanouts") It may be useful to have defragmentation enabled regardless of fanout type. Without that, the AF_PACKET user may have to: 1. Collect fragments from different rings 2. Defragment by itself Signed-off-by: Alexander Drozdov <al.drozdov@...il.com> --- net/packet/af_packet.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/net/packet/af_packet.c b/net/packet/af_packet.c index 9c28cec..99fc628 100644 --- a/net/packet/af_packet.c +++ b/net/packet/af_packet.c @@ -1349,14 +1349,14 @@ static int packet_rcv_fanout(struct sk_buff *skb, struct net_device *dev, return 0; } + if (fanout_has_flag(f, PACKET_FANOUT_FLAG_DEFRAG)) { + skb = ip_check_defrag(skb, IP_DEFRAG_AF_PACKET); + if (!skb) + return 0; + } switch (f->type) { case PACKET_FANOUT_HASH: default: - if (fanout_has_flag(f, PACKET_FANOUT_FLAG_DEFRAG)) { - skb = ip_check_defrag(skb, IP_DEFRAG_AF_PACKET); - if (!skb) - return 0; - } idx = fanout_demux_hash(f, skb, num); break; case PACKET_FANOUT_LB: -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
