* cfg802154: introduce wpan phy flagsAlexander Aring2015-05-195-37/+50
| | | | | | | | | | | | | | | | | | | | | | | This patch introduce a flag property for the wpan phy structure. The current flag settings in ieee802154_hw are accessable in mac802154 layer only which is okay for flags which indicates MAC handling which are done by phy. For real PHY layer settings like cca mode, transmit power, cca energy detection level. The difference between these flags are that the MAC handling flags are only handled in mac802154/HardMac layer e.g. on an interface up. The phy settings are direct netlink calls from nl802154 into the driver layer and the nl802154 need to have a chance to check if the driver supports this handling before sending to the next layer. We also check now on PHY flags while dumping and setting pib attributes. In comparing with MIB attributes the 802.15.4 gives us an default value which we assume when a transceiver implement less functionality. In case of MIB settings the nl802154 layer doesn't need to check on the ieee802154_hw flags then.

| | | | | | | | | | This patch adds check if the value is really changed inside pib/mib.

| | | | | | | | | | | | | | This patch adds support for phy supported handling for all other already existing handling 802.15.4 functionality. We assume now a fully 802.15.4 complaint transceiver at phy allocation. If a transceiver can support 802.15.4 default values only, then the values should be overwirtten by values the transceiver supports. If the transceiver doesn't set the according hardware flags, we assume the 802.15.4 defaults now which cannot be changed.

It is a specific implementation of migration that minimizes reordering by selecting the same victim socket when possible (and by selecting subsequent victims in a round robin fashion, from which its name derives). Changes: v2 -> v3: - statistics: replace unsigned long with __aligned_u64 v1 -> v2: - huge flow detection: run lockless - huge flow detection: replace stored index with random - contention avoidance: test in packet_poll while lock held - contention avoidance: clear pressure sooner packet_poll and packet_recvmsg would clear only if the sock is empty to avoid taking the necessary lock. But, * packet_poll already holds this lock, so a lockless variant __packet_rcv_has_room is cheap. * packet_recvmsg is usually called only for non-ring sockets, which also runs lockless. - preparation: drop "single return" patch packet_rcv_has_room is now a locked wrapper around __packet_rcv_has_room, achieving the same (single footer).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Migrate flows from a socket to another socket in the fanout group not only when the socket is full. Start migrating huge flows early, to divert possible 4-tuple attacks without affecting normal traffic. Introduce fanout_flow_is_huge(). This detects huge flows, which are defined as taking up more than half the load. It does so cheaply, by storing the rxhashes of the N most recent packets. If over half of these are the same rxhash as the current packet, then drop it. This only protects against 4-tuple attacks. N is chosen to fit all data in a single cache line.

This operation is expensive especially if the packet sockets use rings, when a lock has to be acquired. Avoid pounding on the lock by all sockets by temporarily marking a socket as "under memory pressure" when such pressure is detected. While set, only the socket owner may call packet_rcv_has_room on the socket. Once it detects normal conditions, it clears the flag. The socket is not used as a victim by any other socket in the meantime. Under reasonably balanced load, each socket writer frequently calls packet_rcv_has_room and clears its own pressure field. As a backup for when the socket is rarely written to, also clear the flag on reading (packet_recvmsg, packet_poll) if this can be done cheaply (i.e., without calling packet_rcv_has_room). This is only for edge cases. Tested: Ran bench_rollover: a process with 8 sockets in a single fanout group, each pinned to a single cpu that receives one nic recv interrupt. RPS and RFS are disabled. The benchmark uses packet rx_ring, which has to take a lock when determining whether a socket has room. Sent 3.5 Mpps of UDP traffic with sufficient entropy to spread uniformly across the packet sockets (and inserted an iptables rule to drop in PREROUTING to avoid protocol stack processing). Without this patch, all sockets try to migrate traffic to neighbors, causing lock contention when searching for a non- empty neighbor.
