2013-12-19bonding: add num_grat_arp attribute netlink support[email protected]1-0/+1
Add IFLA_BOND_NUM_PEER_NOTIF to allow get/set of bonding parameter num_grat_arp via netlink. Bonding parameter num_unsol_na is synonymous with num_grat_arp, so add only one netlink attribute to represent both bonding parameters.

2013-12-19net-qdisc-hhf: Heavy-Hitter Filter (HHF) qdiscTerry Lam1-0/+25
This patch implements the first size-based qdisc that attempts to differentiate between small flows and heavy-hitters. The goal is to catch the heavy-hitters and move them to a separate queue with less priority so that bulk traffic does not affect the latency of critical traffic. Currently "less priority" means less weight (2:1 in particular) in a Weighted Deficit Round Robin (WDRR) scheduler. In essence, this patch addresses the "delay-bloat" problem due to bloated buffers. In some systems, large queues may be necessary for obtaining CPU efficiency, or due to the presence of unresponsive traffic like UDP, or just a large number of connections with each having a small amount of outstanding traffic. In these circumstances, HHF aims to reduce the HoL blocking for latency sensitive traffic, while not impacting the queues built up by bulk traffic. HHF can also be used in conjunction with other AQM mechanisms such as CoDel. To capture heavy-hitters, we implement the "multi-stage filter" design in the following paper: C. Estan and G. Varghese, "New Directions in Traffic Measurement and Accounting", in ACM SIGCOMM, 2002. Some configurable qdisc settings through 'tc': - hhf_reset_timeout: period to reset counter values in the multi-stage filter (default 40ms) - hhf_admit_bytes: threshold to classify heavy-hitters (default 128KB) - hhf_evict_timeout: threshold to evict idle heavy-hitters (default 1s) - hhf_non_hh_weight: Weighted Deficit Round Robin (WDRR) weight for non-heavy-hitters (default 2) - hh_flows_limit: max number of heavy-hitter flow entries (default 2048) Note that the ratio between hhf_admit_bytes and hhf_reset_timeout reflects the bandwidth of heavy-hitters that we attempt to capture (25Mbps with the above default settings). The false negative rate (heavy-hitter flows getting away unclassified) is zero by the design of the multi-stage filter algorithm. With 100 heavy-hitter flows, using four hashes and 4000 counters yields a false positive rate (non-heavy-hitters mistakenly classified as heavy-hitters) of less than 1e-4.

2013-12-19cfg80211: Add support for QoS mappingKyeyoon Park1-0/+14
This allows QoS mapping from external networks to be implemented as defined in IEEE Std 802.11-2012, 10.24.9. APs can use this to advertise DSCP ranges and exceptions for mapping frames to a specific UP over Wi-Fi. The payload of the QoS Map Set element (IEEE Std 802.11-2012, 8.4.2.97) is sent to the driver through the new NL80211_ATTR_QOS_MAP attribute to configure the local behavior either on the AP (based on local configuration) or on a station (based on information received from the AP).

2013-12-17PCI: Add Virtual Channel to save/restore supportAlex Williamson1-4/+21
While we don't really have any infrastructure for making use of VC support, the system BIOS can configure the topology to non-default VC values prior to boot. This may be due to silicon bugs, desire to reserve traffic classes, or perhaps just BIOS bugs. When we reset devices, the VC configuration may return to default values, which can be incompatible with devices upstream. For instance, Nvidia GRID cards provide a PCIe switch and some number of GPUs, all supporting VC. The power-on default for VC is to support TC0-7 across VC0, however some platforms will only enable TC0/VC0 mapping across the topology. When we do a secondary bus reset on the downstream switch port, the GPU is reset to a TC0-7/VC0 mapping while the opposite end of the link only enables TC0/VC0. If the GPU attempts to use TC1-7, it fails. This patch attempts to provide complete support for VC save/restore, even beyond the minimally required use case above. This includes save/restore and reload of the arbitration table, save/restore and reload of the port arbitration tables, and re-enabling of the channels for VC, VC9, and MFVC capabilities.

2013-12-09packet: introduce PACKET_QDISC_BYPASS socket optionDaniel Borkmann1-0/+1
This patch introduces a PACKET_QDISC_BYPASS socket option, that allows for using a similar xmit() function as in pktgen instead of taking the dev_queue_xmit() path. This can be very useful when PF_PACKET applications are required to be used in a similar scenario as pktgen, but with full, flexible packet payload that needs to be provided, for example. On default, nothing changes in behaviour for normal PF_PACKET TX users, so everything stays as is for applications. New users, however, can now set PACKET_QDISC_BYPASS if needed to prevent own packets from i) reentering packet_rcv() and ii) to directly push the frame to the driver. In doing so we can increase pps (here 64 byte packets) for PF_PACKET a bit: # CPUs -- QDISC_BYPASS -- qdisc path -- qdisc path[**] 1 CPU == 1,509,628 pps -- 1,208,708 -- 1,247,436 2 CPUs == 3,198,659 pps -- 2,536,012 -- 1,605,779 3 CPUs == 4,787,992 pps -- 3,788,740 -- 1,735,610 4 CPUs == 6,173,956 pps -- 4,907,799 -- 1,909,114 5 CPUs == 7,495,676 pps -- 5,956,499 -- 2,014,422 6 CPUs == 9,001,496 pps -- 7,145,064 -- 2,155,261 7 CPUs == 10,229,776 pps -- 8,190,596 -- 2,220,619 8 CPUs == 11,040,732 pps -- 9,188,544 -- 2,241,879 9 CPUs == 12,009,076 pps -- 10,275,936 -- 2,068,447 10 CPUs == 11,380,052 pps -- 11,265,337 -- 1,578,689 11 CPUs == 11,672,676 pps -- 11,845,344 -- 1,297,412 [...] 20 CPUs == 11,363,192 pps -- 11,014,933 -- 1,245,081 [**]: qdisc path with packet_rcv(), how probably most people seem to use it (hopefully not anymore if not needed) The test was done using a modified trafgen, sending a simple static 64 bytes packet, on all CPUs. The trick in the fast "qdisc path" case, is to avoid reentering packet_rcv() by setting the RAW socket protocol to zero, like: socket(PF_PACKET, SOCK_RAW, 0); Tradeoffs are documented as well in this patch, clearly, if queues are busy, we will drop more packets, tc disciplines are ignored, and these packets are not visible to taps anymore. For a pktgen like scenario, we argue that this is acceptable. The pointer to the xmit function has been placed in packet socket structure hole between cached_dev and prot_hook that is hot anyway as we're working on cached_dev in each send path.

2013-12-09Merge tag 'v3.13-rc3' into drm-intel-next-queuedDaniel Vetter55-113/+2059
Linux 3.13-rc3 I need a backmerge for two reasons: - For merging the ppgtt patches from Ben I need to pull in the bdw support. - We now have duplicated calls to intel_uncore_forcewake_reset in the setup code to due 2 different patches merged into -next and 3.13. The conflict is silen so I need the merge to be able to apply Deepak's fixup patch. Conflicts: drivers/gpu/drm/i915/intel_display.c Trivial conflict, it doesn't even show up in the merge diff.
