| H A D | dn_sched_fq_pie.c | diff 325730 Sun Nov 12 01:34:25 MST 2017 truckman MFC r325008 Fix Dummynet AQM packet marking function ecn_mark() and fq_codel / fq_pie schedulers packet classification functions in layer2 (bridge mode). Dummynet AQM packet marking function ecn_mark() and fq_codel/fq_pie schedulers packet classification functions (fq_codel_classify_flow() and fq_pie_classify_flow()) assume mbuf is pointing at L3 (IP) packet. However, this assumption is incorrect if ipfw/dummynet is used to manage layer2 traffic (bridge mode) since mbuf will point at L2 frame. This patch solves this problem by identifying the source of the frame/packet (L2 or L3) and adding ETHER_HDR_LEN offset when converting an mbuf pointer to ip pointer if the traffic is from layer2. More specifically, in dummynet packet tagging function, tag_mbuf(), iphdr_off is set to ETHER_HDR_LEN if the traffic is from layer2 and set to zero otherwise. Whenever an access to IP header is required, mtodo(m, dn_tag_get(m)->iphdr_off) is used instead of mtod(m, struct ip *) to correctly convert mbuf pointer to ip pointer in both L2 and L3 traffic.
