2016-04-21net/mlx5e: Use napi_alloc_skb for RX SKB allocationsTariq Toukan3-10/+7
Instead of netdev_alloc_skb, we use the napi_alloc_skb function which is designated to allocate skbuff's for RX in a channel-specific NAPI instance, and implies the IP packet alignment.

2016-04-21net/mlx5e: Add fragmented memory support for RX multi packet WQETariq Toukan5-68/+514
If the allocation of a linear (physically continuous) MPWQE fails, we allocate a fragmented MPWQE. This is implemented via device's UMR (User Memory Registration) which allows to register multiple memory fragments into ConnectX hardware as a continuous buffer. UMR registration is an asynchronous operation and is done via ICO SQs. Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com> Signed-off-by: David S.

2016-04-21net/mlx5e: Support RX multi-packet WQE (Striding RQ)Tariq Toukan5-44/+349
Introduce the feature of multi-packet WQE (RX Work Queue Element) referred to as (MPWQE or Striding RQ), in which WQEs are larger and serve multiple packets each. Every WQE consists of many strides of the same size, every received packet is aligned to a beginning of a stride and is written to consecutive strides within a WQE. In the regular approach, each regular WQE is big enough to be capable of serving one received packet of any size up to MTU or 64K in case of device LRO is enabled, making it very wasteful when dealing with small packets or device LRO is enabled. For its flexibility, MPWQE allows a better memory utilization (implying improvements in CPU utilization and packet rate) as packets consume strides according to their size, preserving the rest of the WQE to be available for other packets. MPWQE default configuration: Num of WQEs = 16 Strides Per WQE = 2048 Stride Size = 64 byte The default WQEs memory footprint went from 1024*mtu (~1.5MB) to 16 * 2048 * 64 = 2MB per ring. However, HW LRO can now be supported at no additional cost in memory footprint, and hence we turn it on by default and get an even better performance. Performance tested on ConnectX4-Lx 50G. To isolate the feature under test, the numbers below were measured with HW LRO turned off. We verified that the performance just improves when LRO is turned back on. * Netperf single TCP stream: - BW raised by 10-15% for representative packet sizes: default, 64B, 1024B, 1478B, 65536B. * Netperf multi TCP stream: - No degradation, line rate reached. * Pktgen: packet rate raised by 2-10% for traffic of different message sizes: 64B, 128B, 256B, 1024B, and 1500B. * Pktgen: packet loss in bursts of small messages (64byte), single stream: - | num packets | packets loss before | packets loss after | 2K | ~ 1K | 0 | 8K | ~ 6K | 0 | 16K | ~13K | 0 | 32K | ~28K | 0 | 64K | ~57K | ~24K As expected as the driver can receive as many small packets (<=64B) as the number of total strides in the ring (default = 2048 * 16) vs. 1024 (default ring size regardless of packets size) before this feature.

For Ethernet it will provide an "out of buffer" counter which collects the number of all packets that are dropped due to lack of software buffers.

2016-04-21tcp: Fix SOF_TIMESTAMPING_TX_ACK when handling dup acksMartin KaFai Lau1-1/+2
Assuming SOF_TIMESTAMPING_TX_ACK is on. When dup acks are received, it could incorrectly think that a skb has already been acked and queue a SCM_TSTAMP_ACK cmsg to the sk->sk_error_queue. In tcp_ack_tstamp(), it checks 'between(shinfo->tskey, prior_snd_una, tcp_sk(sk)->snd_una - 1)'. If prior_snd_una == tcp_sk(sk)->snd_una like the following packetdrill script, between() returns true but the tskey is actually not acked. e.g. try between(3, 2, 1). The fix is to replace between() with one before() and one !before(). By doing this, the -1 offset on the tcp_sk(sk)->snd_una can also be removed. A packetdrill script is used to reproduce the dup ack scenario. Due to the lacking cmsg support in packetdrill (may be I cannot find it), a BPF prog is used to kprobe to sock_queue_err_skb() and print out the value of serr->ee.ee_data. Both the packetdrill and the bcc BPF script is attached at the end of this commit message.

2016-04-21openvswitch: Orphan skbs before IPv6 defragJoe Stringer1-0/+1
This is the IPv6 counterpart to commit 8282f27449bf ("inet: frag: Always orphan skbs inside ip_defrag()"). Prior to commit 029f7f3b8701 ("netfilter: ipv6: nf_defrag: avoid/free clone operations"), ipv6 fragments sent to nf_ct_frag6_gather() would be cloned (implicitly orphaning) prior to queueing for reassembly. As such, when the IPv6 message is eventually reassembled, the skb->sk for all fragments would be NULL. After that commit was introduced, rather than cloning, the original skbs were queued directly without orphaning. The end result is that all frags except for the first and last may have a socket attached. This commit explicitly orphans such skbs during nf_ct_frag6_gather() to prevent BUG_ON(skb->sk) during a later call to ip6_fragment(). kernel BUG at net/ipv6/ip6_output.c:631!

Jacob provides majority of the changes in this series, starting with the addition of helper functions to reduce code duplication and the amount of code indentation. Fixed the use or should we say abuse of the ethtool stats API, which could result in corrupt memory or misleading statistic output. Added the appropriate rtnl_lock() and rtnl_unlock() to avoid RCU warnings during AER events. Come to find out, the PTP/1588 support is not working with the current version of switch management software and possibly never worked, so just remove support for PTP/1588 for now. Fixed how error responses from the switch manager after a LPORT_MAP request are handled, originally which were silently being ignored. Fixed up code documentation to hopefully ease the code and comment comprehension. Fixed a possible NULL pointer dereference after a kcalloc(), where when writing a new default redirection table, and we needed to populate a new RSS table using ethtool_rxfh_indir_default(). We populate this table into a region of memory allocated using kcalloc() but never check it for NULL. Alex adds support for bulk transmit cleanup for fm10k, like he did for all of our other drivers. Ngai-Mint fixes a number of issues with the unicast and multicast address syncs. Where an issue would occur when the netdev is pre-configured to either multicast mode and is enabled for the first time. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Deleting lport when multicast mode is configured to FM10K_XCAST_MODE_ALLMULTI or FM10K_XCAST_MODE_PROMISC will result in generating orphaned multicast-group entries in the switch manager. Before deleting the lport, reset multicast mode to FM10K_XCAST_MODE_NONE to flush out these multicast-group entries.
