From: wenxu <we...@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: sch_frag: add generic packet fragment support. include/net/act_api.h | 6 ++ include/net/sch_generic.h | 5 +- net/core/dev.c | 2 + net/sched/Makefile | 1 + net/sched/act_api.c | 16 +++++ net/sched/act_ct.c | 3 + net/sched/act_mirred.c | 21 +++++-- net/sched/sch_frag.c | 150 ++++++++++++++++++++++++++++++++++++++++++++++ 8 files changed, 194 insertions(+), 10 deletions(-) create mode 100644 net/sched/sch_frag.c -- 1.8.3.1
