Subash Abhinov Kasiviswanathan 03a5bcaa7e net: ipv6: Add early demux handler for UDP unicast ... While running a single stream UDPv6 test, we observed that amount of CPU spent in NET_RX softirq was much greater than UDPv4 for an equivalent receive rate. The test here was run on an ARM64 based Android system. On further analysis with perf, we found that UDPv6 was spending significant time in the statistics netfilter targets which did socket lookup per packet. These statistics rules perform a lookup when there is no socket associated with the skb. Since there are multiple instances of these rules based on UID, there will be equal number of lookups per skb. By introducing early demux for UDPv6, we avoid the redundant lookups. This also helped to improve the performance (800Mbps -> 870Mbps) on a CPU limited system in a single stream UDPv6 receive test with 1450 byte sized datagrams using iperf. v1->v2: Use IPv6 cookie to validate dst instead of 0 as suggested by Eric CRs-Fixed: 1114946 Change-Id: I2a59058656863c2e20629fe30fbbe3847319f439 Git-commit: 5425077d73e0c8e7e9267ca8397cc0e2293c1fb9 Git-repo: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git Signed-off-by: Subash Abhinov Kasiviswanathan <subashab@codeaurora.org> Signed-off-by: David S.
