Expose the WMM-TSPEC feature flag to nl80211 so later we can also expose an 802.11-TSPEC feature flag (if needed) to differentiate the two cases.

It allows the AP devices to keep track of the hardware-address-to-IP-address mapping of the mobile devices within the WLAN network. The AP will learn this mapping via observing DHCP, ARP, and NS/NA frames. When a request for such information is made (i.e. ARP request, Neighbor Solicitation), the AP will respond on behalf of the associated mobile device. In the process of doing so, the AP will drop the multicast request frame that was intended to go out to the wireless medium. It was recommended at the LKS workshop to do this implementation in the bridge layer. vxlan.c is already doing something very similar. The DHCP snooping code will be added to the userspace application (hostapd) per the recommendation. This RFC commit is only for IPv4. A similar approach in the bridge layer will be taken for IPv6 as well. Signed-off-by: Kyeyoon Park Signed-off-by: David S.

Preferred addresses will still take precedence over optimistic addresses, subject to other ranking in the source address selection algorithm. This is useful where different interfaces are connected to different networks from different ISPs (e.g., a cell network and a home wifi network). The current behaviour complies with RFC 3484/6724, and it makes sense if the host has only one interface, or has multiple interfaces on the same network (same or cooperating administrative domain(s), but not in the multiple distinct networks case. For example, if a mobile device has an IPv6 address on an LTE network and then connects to IPv6-enabled wifi, while the wifi IPv6 address is undergoing DAD, IPv6 connections will try use the wifi default route with the LTE IPv6 address, and will get stuck until they time out. Also, because optimistic nodes can receive frames, issue an RTM_NEWADDR as soon as DAD starts (with the IFA_F_OPTIMSTIC flag appropriately set). A second RTM_NEWADDR is sent if DAD completes (the address flags have changed), otherwise an RTM_DELADDR is sent. Also: add an entry in ip-sysctl.txt for optimistic_dad.

Then split a set of million of sockets into worker threads, each one using epoll() to manage events on its own socket pool. Ideally, we want one thread per RX/TX queue/cpu, but we have no way to know after accept() or connect() on which queue/cpu a socket is managed. We normally use one cpu per RX queue (IRQ smp_affinity being properly set), so remembering on socket structure which cpu delivered last packet is enough to solve the problem. After accept(), connect(), or even file descriptor passing around processes, applications can use : int cpu; socklen_t len = sizeof(cpu); getsockopt(fd, SOL_SOCKET, SO_INCOMING_CPU, &cpu, &len); And use this information to put the socket into the right silo for optimal performance, as all networking stack should run on the appropriate cpu, without need to send IPI (RPS/RFS).

The configuration for this supports an arbitrary MAC address value and mask, so that any kind of configuration (e.g. fixed OUI or full 46-bit random) can be requested. Full 46-bit random is the default when no other configuration is passed. Also add a small helper function to use the addr/mask correctly.
