2016-07-14pktgen: add sample script pktgen_sample05_flow_per_thread.shJesper Dangaard Brouer1-0/+81
This pktgen sample script is useful for scalability testing a receiver. The script will simply generate one flow per thread (option -t N) using the thread number as part of the source IP-address. The single flow sample (pktgen_sample03_burst_single_flow.sh) have become quite popular, but it is important that developers also make sure to benchmark scalability of multiple receive queues.

2016-07-14pktgen: add sample script pktgen_sample04_many_flows.shJesper Dangaard Brouer2-67/+93
Adding a pktgen sample script that demonstrates how to use pktgen for simulating flows. Script will generate a certain number of concurrent flows ($FLOWS) and each flow will contain $FLOWLEN packets, which will be send back-to-back, before switching to a new flow, due to flag FLOW_SEQ. This script obsoletes the old sample script 'pktgen.conf-1-1-flows', which is removed. Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Saeed Mahameed says: ==================== Mellanox 100G mlx5 Bulk flow statistics and SRIOV TC offloads This series from Amir and Or deals with two enhancements for the mlx5 TC offloads. The 1st two patches add bulk reading of flow counters. Few bulk counter queries are used instead of issuing thousands firmware commands per second to get statistics of all flows set to HW. The next patches add TC based SRIOV offloading to mlx5, as a follow up for the e-switch offloads mode and the VF representors. When the e-switch is set to the (new) "offloads" mode, we can now offload TC/flower drop and forward rules, the forward action we offload is TC mirred/redirect. The above is done by the VF representor netdevices exporting the setup_tc ndo where from there we're re-using and enhancing the existing mlx5 TC offloads sub-module which now works for both the NIC and the SRIOV cases. The series is applied on top b38a75d2d324 ('mlxsw: core: Trace EMAD messages') and it has no merge issues with the on-going net submission ('mlx5 tx timeout watchdog fixes') V2: - Fixed compilation warning. ==================== Signed-off-by: David S.

2016-07-14net/mlx5: E-Switch, Use two priorities for SRIOV offloads modeOr Gerlitz3-15/+42
In the offloads mode, some slow path rules are added by the driver (e.g send-to-vport), while offloaded rules are to be added from upper layers. The slow path rules have lower priority and we don't want matching on offloaded rules to suffer from extra steering hops related to the slow path rules. We use two priorities, one for offloaded rules (fast path), and one for the control rules (slow path). To allow for that, we enable two priorities for the FDB namespace in the FS core code.

2016-07-14net/mlx5: Introduce bulk reading of flow countersAmir Vadai4-24/+146
This commit utilize the ability of ConnectX-4 to bulk read flow counters. Few bulk counter queries could be done instead of issuing thousands of firmware commands per second to get statistics of all flows set to HW, such as those programmed when we offload tc filters. Counters are stored sorted by hardware id, and queried in blocks (id + number of counters). Due to hardware requirement, start of block and number of counters in a block must be four aligned.

2016-07-13sctp: only check for ECN if peer is using itMarcelo Ricardo Leitner1-3/+2
Currently only read-only checks are performed up to the point on where we check if peer is ECN capable, checks which we can avoid otherwise.

2016-07-13sctp: do not clear chunk->ecn_ce_done flagMarcelo Ricardo Leitner1-1/+0
We should not clear that flag when switching to a new skb from a GSO skb because it would cause ECN processing to happen multiple times per GSO skb, which is not wanted. Instead, let it be processed once per chunk. That is, in other words, once per IP header available.

2016-07-13sctp: avoid identifying address family many times for a chunkMarcelo Ricardo Leitner5-21/+9
Identifying address family operations during rx path is not something expensive but it's ugly to the eye to have it done multiple times, specially when we already validated it during initial rx processing. This patch takes advantage of the now shared sctp_input_cb and make the pointer to the operations readily available.

2016-07-13sctp: allow GSO frags to access the chunk tooMarcelo Ricardo Leitner8-11/+38
SCTP will try to access original IP headers on sctp_recvmsg in order to copy the addresses used. There are also other places that do similar access to IP or even SCTP headers. But after 90017accff61 ("sctp: Add GSO support") they aren't always there because they are only present in the header skb. SCTP handles the queueing of incoming data by cloning the incoming skb and limiting to only the relevant payload. This clone has its cb updated to something different and it's then queued on socket rx queue. Thus we need to fix this in two moments. For rx path, not related to socket queue yet, this patch uses a partially copied sctp_input_cb to such GSO frags. This restores the ability to access the headers for this part of the code. Regarding the socket rx queue, it removes iif member from sctp_event and also add a chunk pointer on it. With these changes we're always able to reach the headers again. The biggest change here is that now the sctp_chunk struct and the original skb are only freed after the application consumed the buffer. Note however that the original payload was already like this due to the skb cloning. For iif, SCTP's IPv4 code doesn't use it, so no change is necessary. IPv6 now can fetch it directly from original's IPv6 CB as the original skb is still accessible. In the future we probably can simplify sctp_v*_skb_iif() stuff, as sctp_v4_skb_iif() was called but it's return value not used, and now it's not even called, but such cleanup is out of scope for this change.

2016-07-13sctp: reorder sctp_ulpevent and shrink msg_flagsMarcelo Ricardo Leitner2-7/+7
The next patch needs 8 bytes in there. sctp_ulpevent has a hole due to bad alignment; msg_flags is using 4 bytes while it actually uses only 2, so we shrink it, and iif member (4 bytes) which can be easily fetched from another place once the next patch is there, so we remove it and thus creating space for 8 bytes.

2016-07-11bpf: make inode code explicitly non-modularPaul Gortmaker1-3/+1
The Kconfig currently controlling compilation of this code is: init/Kconfig:config BPF_SYSCALL init/Kconfig: bool "Enable bpf() system call" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. Note that MODULE_ALIAS is a no-op for non-modular code. We replace module.h with init.h since the file does use __init.

2016-07-11nfp: check idx is -ENOSPC before using it is an indexColin Ian King1-1/+1
idx can be returned as -ENOSPC, so we should check for this first before using it as an index into nn->vxlan_usecnt[] to avoid an out of bounds array offset read.

2016-07-11tunnels: correct conditional build of MPLS and IPv6Simon Horman1-12/+13
Using a combination if #if conditionals and goto labels to unwind tunnel4_init seems unwieldy. This patch takes a simpler approach of directly unregistering previously registered protocols when an error occurs. This fixes a number of problems with the current implementation including the potential presence of labels when they are unused and the potential absence of unregister code when it is needed.

2016-07-11Merge branch 'sctp-rfc7496-support'David S. Miller9-13/+447
Xin Long says: ==================== sctp: implement rfc7496 in sctp This patchset implements "Additional Policies for the Partially Reliable Stream Control Transmission Protocol Extension" described on RFC7496. The Partially Reliable SCTP (PR-SCTP) extension defined in [RFC3758] provides a generic method for senders to abandon user messages. The decision to abandon a user message is sender side only, and the exact condition is called a "PR-SCTP policy". This patchset implements 3 policies: 1. Timed Reliability: This allows the sender to specify a timeout for a user message after which the SCTP stack abandons the user message. 2. Limited Retransmission Policy: Allows limitation of the number of retransmissions. 3. Priority Policy: Allows removal of lower-priority messages if space for higher-priority messages is needed in the send buffer. Patch 1-3 add some sockopts in sctp to set/get pr_sctp policy status. Patch 4-6 implement these 3 policies one by one. ==================== Acked-by: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
