git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-10-02 This series contains updates to fm10k, igb, ixgbe and i40e. Alex provides two updates to the fm10k driver. First reduces the buffer size to 2k for all page sizes, since most frames only have a 1500 MTU so supporting a buffer size larger than this is somewhat wasteful. Second fixes an issue where the number of transmit queues was not being updated, so added the lines necessary to update the number of transmit queues. Rick Jones provides two patches to convert ixgbe, igb and i40e to use dev_consume_skb_any(). Emil provides two patches for ixgbe, first cleans up a couple of wait loops on auto-negotiation that were not needed. Second fixes an issue reported by Fujitsu/Red Hat, which consolidates the logic behind the dynamically setting of TXDCTL.WTHRESH depending on interrupt throttle rate (ITR) setting regardless of BQL. Ethan Zhao provides a cleanup patch for ixgbe where he noticed a duplicate define. Bernhard Kaindl provides a patch for igb to remove a source of latency spikes by not calling code that uses mdelay() for feeding a PHY stat while being called with a spinlock held. Todd bumps the igb version based on the recent changes. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2014-10-03qdisc: validate skb without holding lockEric Dumazet
Validation of skb can be pretty expensive : GSO segmentation and/or checksum computations. We can do this without holding qdisc lock, so that other cpus can queue additional packets. Trick is that requeued packets were already validated, so we carry a boolean so that sch_direct_xmit() can validate a fresh skb list, or directly use an old one. Tested on 40Gb NIC (8 TX queues) and 200 concurrent flows, 48 threads host. Turning TSO on or off had no effect on throughput, only few more cpu cycles. Lock contention on qdisc lock disappeared. Same if disabling TX checksum offload. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-10-03Merge branch 'qdisc_bulk_dequeue'David S. Miller
Jesper Dangaard Brouer says: ==================== qdisc: bulk dequeue support This patchset uses DaveM's recent API changes to dev_hard_start_xmit(), from the qdisc layer, to implement dequeue bulking. Patch01: "qdisc: bulk dequeue support for qdiscs with TCQ_F_ONETXQUEUE" - Implement basic qdisc dequeue bulking - This time, 100% relying on BQL limits, no magic safe-guard constants Patch02: "qdisc: dequeue bulking also pickup GSO/TSO packets" - Extend bulking to bulk several GSO/TSO packets - Seperate patch, as it introduce a small regression, see test section. We do have a patch03, which exports a userspace tunable as a BQL tunable, that can byte-cap or disable the bulking/bursting. But we could not agree on it internally, thus not sending it now. We basically strive to avoid adding any new userspace tunable. Testing patch01: ================ Demonstrating the performance improvement of qdisc dequeue bulking, is tricky because the effect only "kicks-in" once the qdisc system have a backlog. Thus, for a backlog to form, we need either 1) to exceed wirespeed of the link or 2) exceed the capability of the device driver. For practical use-cases, the measureable effect of this will be a reduction in CPU usage 01-TCP_STREAM: -------------- Testing effect for TCP involves disabling TSO and GSO, because TCP already benefit from bulking, via TSO and especially for GSO segmented packets. This patch view TSO/GSO as a seperate kind of bulking, and avoid further bulking of these packet types. The measured perf diff benefit (at 10Gbit/s) for a single netperf TCP_STREAM were 9.24% less CPU used on calls to _raw_spin_lock() (mostly from sch_direct_xmit). If my E5-2695v2(ES) CPU is tuned according to: http://netoptimizer.blogspot.dk/2014/04/basic-tuning-for-network-overload.html Then it is possible that a single netperf TCP_STREAM, with GSO and TSO disabled, can utilize all bandwidth on a 10Gbit/s link. This will then cause a standing backlog queue at the qdisc layer. Trying to pressure the system some more CPU util wise, I'm starting 24x TCP_STREAMs and monitoring the overall CPU utilization. This confirms bulking saves CPU cycles when it "kicks-in". Tool mpstat, while stressing the system with netperf 24x TCP_STREAM, shows: * Disabled bulking: sys:2.58% soft:8.50% idle:88.78% * Enabled bulking: sys:2.43% soft:7.66% idle:89.79% 02-UDP_STREAM ------------- The measured perf diff benefit for UDP_STREAM were 6.41% less CPU used on calls to _raw_spin_lock(). 24x UDP_STREAM with packet size -m 1472 (to avoid sending UDP/IP fragments). 03-trafgen driver test ---------------------- The performance of the 10Gbit/s ixgbe driver is limited due to updating the HW ring-queue tail-pointer on every packet. As previously demonstrated with pktgen. Using trafgen to send RAW frames from userspace (via AF_PACKET), and forcing it through qdisc path (with option --qdisc-path and -t0), sending with 12 CPUs. I can demonstrate this driver layer limitation: * 12.8 Mpps with no qdisc bulking * 14.8 Mpps with qdisc bulking (full 10G-wirespeed) Testing patch02: ================ Testing Bulking several GSO/TSO packets: Measuring HoL (Head-of-Line) blocking for TSO and GSO, with netperf-wrapper. Bulking several TSO show no performance regressions (requeues were in the area 32 requeues/sec for 10G while transmitting approx 813Kpps). Bulking several GSOs does show small regression or very small improvement (requeues were in the area 8000 requeues/sec, for 10G while transmitting approx 813Kpps). Using ixgbe 10Gbit/s with GSO bulking, we can measure some additional latency. Base-case, which is "normal" GSO bulking, sees varying high-prio queue delay between 0.38ms to 0.47ms. Bulking several GSOs together, result in a stable high-prio queue delay of 0.50ms. Corrosponding to: (10000*10^6)*((0.50-0.47)/10^3)/8 = 37500 bytes (10000*10^6)*((0.50-0.38)/10^3)/8 = 150000 bytes 37500/1500 = 25 pkts 150000/1500 = 100 pkts Using igb at 100Mbit/s with GSO bulking, shows an improvement. Base-case sees varying high-prio queue delay between 2.23ms to 2.35ms diff of 0.12ms corrosponding to 1500 bytes at 100Mbit/s. Bulking several GSOs together, result in a stable high-prio queue delay of 2.23ms. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2014-10-03qdisc: dequeue bulking also pickup GSO/TSO packetsJesper Dangaard Brouer
The TSO and GSO segmented packets already benefit from bulking on their own. The TSO packets have always taken advantage of the only updating the tailptr once for a large packet. The GSO segmented packets have recently taken advantage of bulking xmit_more API, via merge commit 53fda7f7f9e8 ("Merge branch 'xmit_list'"), specifically via commit 7f2e870f2a4 ("net: Move main gso loop out of dev_hard_start_xmit() into helper.") allowing qdisc requeue of remaining list. And via commit ce93718fb7cd ("net: Don't keep around original SKB when we software segment GSO frames."). This patch allow further bulking of TSO/GSO packets together, when dequeueing from the qdisc. Testing: Measuring HoL (Head-of-Line) blocking for TSO and GSO, with netperf-wrapper. Bulking several TSO show no performance regressions (requeues were in the area 32 requeues/sec). Bulking several GSOs does show small regression or very small improvement (requeues were in the area 8000 requeues/sec). Using ixgbe 10Gbit/s with GSO bulking, we can measure some additional latency. Base-case, which is "normal" GSO bulking, sees varying high-prio queue delay between 0.38ms to 0.47ms. Bulking several GSOs together, result in a stable high-prio queue delay of 0.50ms.

2014-10-03qdisc: bulk dequeue support for qdiscs with TCQ_F_ONETXQUEUEJesper Dangaard Brouer
Based on DaveM's recent API work on dev_hard_start_xmit(), that allows sending/processing an entire skb list. This patch implements qdisc bulk dequeue, by allowing multiple packets to be dequeued in dequeue_skb(). The optimization principle for this is two fold, (1) to amortize locking cost and (2) avoid expensive tailptr update for notifying HW. (1) Several packets are dequeued while holding the qdisc root_lock, amortizing locking cost over several packet. The dequeued SKB list is processed under the TXQ lock in dev_hard_start_xmit(), thus also amortizing the cost of the TXQ lock. (2) Further more, dev_hard_start_xmit() will utilize the skb->xmit_more API to delay HW tailptr update, which also reduces the cost per packet. One restriction of the new API is that every SKB must belong to the same TXQ. This patch takes the easy way out, by restricting bulk dequeue to qdisc's with the TCQ_F_ONETXQUEUE flag, that specifies the qdisc only have attached a single TXQ. Some detail about the flow; dev_hard_start_xmit() will process the skb list, and transmit packets individually towards the driver (see xmit_one()). In case the driver stops midway in the list, the remaining skb list is returned by dev_hard_start_xmit(). In sch_direct_xmit() this returned list is requeued by dev_requeue_skb(). To avoid overshooting the HW limits, which results in requeuing, the patch limits the amount of bytes dequeued, based on the drivers BQL limits. In-effect bulking will only happen for BQL enabled drivers. Small amounts for extra HoL blocking (2x MTU/0.24ms) were measured at 100Mbit/s, with bulking 8 packets, but the oscillating nature of the measurement indicate something, like sched latency might be causing this effect. More comparisons show, that this oscillation goes away occationally. Thus, we disregard this artifact completely and remove any "magic" bulking limit. For now, as a conservative approach, stop bulking when seeing TSO and segmented GSO packets. They already benefit from bulking on their own. A followup patch add this, to allow easier bisect-ability for finding regressions. Jointed work with Hannes, Daniel and Florian.

When a full chip reset is done, all the queues across all VIFs are stopped, but if MCC is enabled, only the queues of the current context is awakened, when we complete the reset. This results in unfairness for the inactive context. Since frames are queued internally in the driver if there is a context mismatch, we can awaken all the queues when coming out of a reset.

* Consistently use the multi-line comment style for networking code: /* This * That * The other thing */ * Use single-line comment style for comments with only one line of text. * In general follow the leading '*' of each line of a comment with a single space and then text. * Add missing line break between functions, remove double line break, align comments to previous lines whenever possible.

2014-10-02netfilter: explicit module dependency between br_netfilter and physdevPablo Neira Ayuso
You can use physdev to match the physical interface enslaved to the bridge device. This information is stored in skb->nf_bridge and it is set up by br_netfilter. So, this is only available when iptables is used from the bridge netfilter path. Since 34666d4 ("netfilter: bridge: move br_netfilter out of the core"), the br_netfilter code is modular. To reduce the impact of this change, we can autoload the br_netfilter if the physdev match is used since we assume that the users need br_netfilter in place.

2014-10-02netfilter: nf_tables: allow to filter from prerouting and postroutingPablo Neira Ayuso
This allows us to emulate the NAT table in ebtables, which is actually a plain filter chain that hooks at prerouting, output and postrouting. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2014-10-02netfilter: nft_compat: remove incomplete 32/64 bits arch compat codePablo Neira Ayuso
This code was based on the wrong asumption that you can probe based on the match/target private size that we get from userspace. This doesn't work at all when you have to dump the info back to userspace since you don't know what word size the userspace utility is using. Currently, the extensions that require arch compat are limit match and the ebt_mark match/target. The standard targets are not used by the nft-xt compat layer, so they are not affected. We can work around this limitation with a new revision that uses arch agnostic types. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2014-10-02netfilter: use IS_ENABLED(CONFIG_BRIDGE_NETFILTER)Pablo Neira Ayuso
In 34666d4 ("netfilter: bridge: move br_netfilter out of the core"), the bridge netfilter code has been modularized. Use IS_ENABLED instead of ifdef to cover the module case. Fixes: 34666d4 ("netfilter: bridge: move br_netfilter out of the core") Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2014-10-02netfilter: move nf_send_resetX() code to nf_reject_ipvX modulesPablo Neira Ayuso
Move nf_send_reset() and nf_send_reset6() to nf_reject_ipv4 and nf_reject_ipv6 respectively. This code is shared by x_tables and nf_tables. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2014-10-02netfilter: nft_reject: introduce icmp code abstraction for inet and bridgePablo Neira Ayuso
This patch introduces the NFT_REJECT_ICMPX_UNREACH type which provides an abstraction to the ICMP and ICMPv6 codes that you can use from the inet and bridge tables, they are: * NFT_REJECT_ICMPX_NO_ROUTE: no route to host - network unreachable * NFT_REJECT_ICMPX_PORT_UNREACH: port unreachable * NFT_REJECT_ICMPX_HOST_UNREACH: host unreachable * NFT_REJECT_ICMPX_ADMIN_PROHIBITED: administratevely prohibited You can still use the specific codes when restricting the rule to match the corresponding layer 3 protocol. I decided to not overload the existing NFT_REJECT_ICMP_UNREACH to have different semantics depending on the table family and to allow the user to specify ICMP family specific codes if they restrict it to the corresponding family.

2014-10-02Bluetooth: 6lowpan: Check transmit errors for multicast packetsJukka Rissanen
We did not return error if multicast packet transmit failed. This might not be desired so return error also in this case. If there are multiple 6lowpan devices where the multicast packet is sent, then return error even if sending to only one of them fails.
