2016-04-11examples/vm_power_manager: fix libvirt dependency checkMarvin Liu
vm_power_manager utilize libvirt API virDomainGetVcpuPinInfo to retrieve domU vcpu information. This API is implemented from version 0.9.3.

2016-04-06examples/l3fwd: fix crash with gcc 5Tomasz Kulasek
It seems that with gcc >5.x and -O2/-O3 optimization breaks packet grouping algorithm. When last packet pointer "lp" and "pnum->u64" buffer points the same memory buffer, high optimization can cause unpredictable results. It seems that assignment of precalculated group sizes may interfere with initialization of new group size when lp points value inside current group and didn't should be changed. With gcc >5.x and optimization we cannot be sure which assignment will be done first, so the group size can be counted incorrectly. This patch eliminates intersection of assignment of initial group size (lp[0] = 1) and precalculated group sizes when gptbl[v].idx < 4.

2016-03-31examples/l3fwd: fix size of destination port idsKonstantin Ananyev
Originally l3fwd used 16-bit value to store dest_port value. To accommodate 24-bit nexthop dest_port was increased to 32-bit, though some further packet processing code remained unchanged and still expects dest_port to be 16-bit. That is not correct and can cause l3fwd invalid behaviour or even process crash/hang on some input packet patterns. For the fix, I choose the simplest approach and restored dest_port as 16-bit value, plus necessary conversions from 32 to 16 bit values after lpm_lookupx4.

2016-03-25examples/l3fwd: fix using packet type blindlyJianfeng Tan
As a example to use ptype info, l3fwd needs firstly to use rte_eth_dev_get_supported_ptypes() API to check if device and/or its PMD driver will parse and fill the needed packet type; if not, use the newly added option, --parse-ptype, to analyze it in the callback softly. As the mode of EXACT_MATCH uses the 5 tuples to caculate hash, so we narrow down its scope to: a. ip packets with no extensions, and b. L4 payload should be either tcp or udp. Note: this patch does not completely solve the issue, "cannot run l3fwd on virtio or other devices", because hw_ip_checksum may be not supported by the devices. Currently we can: a. remove this requirements, or b. wait for virtio front end (pmd) to support it.

2016-03-25examples/l3fwd: fix validation for queue id of config tupleReshma Pattan
Added validation for queue id of config parameter tuple. This validation enforces user to enter queue ids of a port from 0 and in sequence. This additional validation on queue ids avoids ixgbe crash caused by null rxq pointer access inside ixgbe_dev_rx_init. Reason for null rxq is, L3fwd application allocates memory only for queues passed by user. But rte_eth_dev_start tries to initialize rx queues in sequence from 0 to nb_rx_queues, which is not true and coredump while accessing the unallocated queue .

For instance, in this implementation, hash value computed over specific header fields of the incoming packets has been used to spread traffic uniformly among the output ports. The following pass-through configuration can be used for implementing load balancing function over ipv4 traffic; [PIPELINE0] type = PASS-THROUGH core = 0 pktq_in = RXQ0.0 RXQ1.0 RXQ2.0 RXQ3.0 pktq_out = TXQ0.0 TXQ1.0 TXQ2.0 TXQ3.0 dma_src_offset = 278; mbuf (128) + headroom (128) + 1st ethertype offset (14) + ttl offset within ip header = 278 (ipv4) dma_dst_offset = 128; mbuf (128) dma_size = 16 dma_src_mask = 00FF0000FFFFFFFFFFFFFFFFFFFFFFFF dma_hash_offset = 144; (dma_dst_offset+dma_size) lb = hash Signed-off-by: Jasvinder Singh <jasvinder.singh@intel.com> Acked-by: Cristian Dumitrescu <cristian.dumitrescu@intel.com>
2016-03-13examples/ip_pipeline: add pcap file dumpFan Zhang
This patch add packet dumping feature to ip_pipeline. Output port type SINK now supports dumping packets to PCAP file before releasing mbuf back to mempool. This feature can be applied by specifying parameters in configuration file as shown below: [PIPELINE1] type = PASS-THROUGH core = 1 pktq_in = SOURCE0 SOURCE1 pktq_out = SINK0 SINK1 pcap_file_wr = /path/to/eth1.pcap /path/to/eth2.pcap pcap_n_pkt_wr = 80 0 The configuration section "pcap_file_wr" contains full path and name of the PCAP file which the packets will be dumped to. If multiple SINKs exists, each shall have its own PCAP file path listed in this section, separated by spaces. Multiple SINK ports shall NOT share same PCAP file to be dumped. The configuration section "pcap_n_pkt_wr" contains integer value(s) and indicates the maximum number of packets to be dumped to the PCAP file. If this value is "0", the "infinite" dumping mode will be used. If this value is N (N > 0), the dumping will be finished when the number of packets dumped to the file reaches N. To enable PCAP dumping support to IP pipeline, the compiler option CONFIG_RTE_PORT_PCAP must be set to 'y'. It is possible to disable this feature by removing "pcap_file_wr" and "pcap_n_pkt_wr" lines from the configuration file.
