2019-02-26Move pcap rx/tx trace code out of the dpdk pluginDave Barach1-0/+16
Moved code to the ethernet input node, and the interface output path(s). Since we no longer skip ethernet-input, there's no reason for device drivers to know anything about pcap rx tracing, etc. Change-Id: I08d32fb1b90cbee1bd4f609837d533e047b36fa4 Signed-off-by: Dave Barach <dave@barachs.net>
2019-02-25buffer chain linearizationKlement Sekera2-97/+125
Rewrite vlib_buffer_chain_linearize function so that it works as intended. Linearize buffer chains coming out of reassembly to work around some dpdk-tx issues. Note that this is not a complete workaround as a sufficiently large packet will still cause the resulting chain to be too long. Drop features from reassembly code which relies on knowing which and how many buffers were freed during linearization, buffer counts and tracing capabilities for these cases.

2019-02-20calculate per-thread time offsetDave Barach3-1/+66
The main thread squirrels away vlib_time_now (&vlib_global_main), worker threads use it to calculate an offset in f64 seconds from their own vlib_time_now(vm) value. We use that offset until the next barrier sync. Thanks to Damjan for the suggestion. Change-Id: If56cdfe68e5ad8ac3b0d0fc885dc3ba556cd1215 Signed-off-by: Dave Barach <dave@barachs.net>

2019-01-24perfmon plugin: 2-way parallel stat collectionDave Barach4-58/+54
As a FUD reduction measure, this patch implements 2-way parallel counter collection. Synthetic stat component counter pairs run at the same time. Running two counters (of any kind) at the same time naturally reduces the aggregate time required by an approximate factor-of-2, depending on whether an even or odd number of stats have been requested. I don't completely buy the argument that computing synthetic stats such as instructions-per-clock will be inaccurate if component counter values are collected sequentially. Given uniform traffic pattern, it must make no difference. As the collection interval increases, the difference between serial and parallel component counter collection will approach zero, see also the Central Limit theorem.

2019-01-17pci: fix strncpy warningsStephen Hemminger1-4/+4
Doing strncpy(ifr.ifr_name, s, sizeof(ifr.ifr_name)) will cause a warning about string truncation with GCC 8 (and other tools). Fix this by using sizeof(ifr.ifr_name) - 1. Also, there is no need to manually zero the end of the string since the whole ifr structure is already zeroed by memset.

2019-01-07Handle buffer alloc failure in vlib_buffer_add_dataDave Barach2-8/+9
It's not OK to crash due to a transient buffer allocation failure. Return 1 if the requested operation failed, otherwise 0. Buffer index parameter change to a value-result, so the caller can differentiate between partial and complete allocation failure: callers which request an initial allocation (inbound bi = ~0) need to check the (out) value to decide whether or not to call vlib_buffer_free(...).

2018-12-04Add VNET_BUFFER_F_AVAIL definitionsDave Barach1-0/+1
Add a check to make sure that the vlib and vnet buffer flag bit definitions do not overlap. The VNET_BUFFER_F_AVAIL1...8 definitions allow out-of-tree codes to: #define VNET_BUFFER_F_MY_USECASE VNET_BUFFER_F_AVAIL1 and so on. This avoids introducing irrelevant and/or proprietary bit definitions into vnet/buffer.h, and hopefully minimizes merge pain for everyone involved.
