Subject: [PATCH v9 net-next 0/3] net/sched: fix over mtu packet of defrag in
Date: Wed, 11 Nov 2020 17:19:29 +0800	[thread overview]
Message-ID: <1605086372-22822-1-git-send-email-wenxu@ucloud.cn> (raw)

From: wenxu <wenxu@ucloud.cn>

Currently kernel tc subsystem can do conntrack in act_ct. But when several
fragment packets go through the act_ct, function tcf_ct_handle_fragments
will defrag the packets to a big one. But the last action will redirect
mirred to a device which maybe lead the reassembly big packet over the mtu
of target device.

The first patch fix miss init the qdisc_skb_cb->mru
The send one refactor the hanle of xmit in act_mirred and prepare for the
third one
The last one add implict packet fragment support to fix the over mtu for
defrag in act_ct.

wenxu (3):
  net/sched: fix miss init the mru in qdisc_skb_cb
  net/sched: act_mirred: refactor the handle of xmit
  net/sched: act_frag: add implict packet fragment support.
