2020-02-11vlib: Skip core 0 if workers are configured.Jon Loeliger1-0/+15
According to the description in the startup.conf, the assignment of worker threads starts with the lcore following the main_lcore. A non-zero skip_cores will correctly achieve this assignment. However, prior to this patch when workers are assigned, the code picks up and assigns core 0 even thought it shouldn't. This patch determins if a non-zero number of workers are desired and if so, marks CPU unavailable for a worker assignment.

2020-02-06vlib: add plugin override supportDave Barach6-36/+205
Allow a plugin to override (suppress loading of) other plugins. This mechanism allows a developer to prevent specific plugins from being loaded. To do so, provide an "overrides" list in the plugin definition: VLIB_PLUGIN_REGISTER () = { <snip> .overrides = "avf_plugin.so,ioam_plugin.so,dpdk_plugin.so", }; or some such. Simply list the plugins in question as shown above. The .overrides structure member is limited to 256 octets. The named .elf section mechanism used to discover the vlib_plugin_registration_t's precludes the use of a variable-length array of strings. Use the vlib log to eliminate plugin and built-in vat plugin loader console spew. Added vlib_log_register_class_rate_limit(...) to allow procedural configuration of the log rate-limit. We *never* want to rate-limit plugin loader messages. Type: feature Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I0a9327b8cf5508482f057342783252112cb44170

2019-11-01vlib: Handle race in thread barrier processingAlexander Kabaev1-1/+1
When CLIB_DEBUG is enabled, vlib_foreach_main macro asserts that vlib_main it currently looks at is safely parked in barrier, by checkling that vlib_main->parked_at_barrier is not 0. Unfortunately, the check is racy - workers first increment the atomic counter to indicate that they have reached the barrier and _then_ set this_main->parked_at_barrier to 1. For the last worker to suspend this opens the race - main thread is free to execute and assert immediately after atomic counter has been incremented, before worker gets to write to own parked_at_barrier. Fix this by simply swapping the order of two operations. Type: fix Signed-off-by: Alexnader Kabaev <kan@FreeBSD.org> Change-Id: Iae47abd6ca0be1c5413f5ecaefabc64cd7eac2ed

2019-10-20vlib: linux: fix wrong iommu_group value issue when using dpdk-pluginYulong Pei1-22/+19
When VPP work with dpdk-plugin, linux_vfio_main_t->container_fd is always -1 since it never have chance to run open("/dev/vfio/vfio") to get the fd. But this lead to a potential issue of VPP, that is, when start VPP without uio-driver field setup in /etc/vpp/startup.conf, VPP will run to automatical select uio driver in vlib_pci_bind_to_uio() and the function depend on iommu_group value to decide to work on vfio or vfio-noiommu mode. Since in vlib_pci_get_device_info() have the condition container_fd != -1, so the iommu_group value will be always -1 at this scenario, this caused that VPP mistake to run with vfio-noiommu driver on intel_iommu=on state. Actually in order to get iommu_group and iommu_group/name value, no need to depend on linux_vfio_main_t->container_fd value, so the fix remove the condition lvm->container_fd != -1, then it can get the correct iommu_group value.

2019-10-07vlib: move thread barrier around mod of global node next dataChristian E. Hopps1-6/+5
The old code modified the node next array prior to obtaining the thread barrier. Then it updated the runtime node data, and upon barrier release caused reforking of each worker thread. The reforking clones the main thread nodes and reconstructs the runtime node structure. This cloning is not 100% "deep" in the sense that the node next array is shared (i.e., only the pointer is copied). So prior to the barrier being obtained the node's next array is being changed while workers are actively using it (bad). Treating the node next array as read-only in the workers and sharing it is a decent optimization so instead of trying to fix that just move the barrier a little earlier in the process to protect the node next array as well. This was tripping an assert in next frame ownership change by way of the ip4-arp node. The assert verifies that the node's next array length is equal to the runtime next node count. The race above was lost and the node next array data was updated in the main thread while the arp code was still executing in a worker. This was being hit when many arp requests were being sent from both ends of a tunnel during which the add next node function was called, which often led to an assert b/c the next node array was out of sync with the runtime next node count. - PS#2 update - move barrier sync to just above code that modifies state.

The 9af7e2e87e used a comparison that fd is >= 0 to check that the pcap needs closing. While the pcap_close() function does reset the file descriptor to -1, the freshly initialized structure has it equal to 0. This causes the VPP to close stdin if the packets are being seen on pg interface without the capture file being opened. This triggers the vpp attempting to read from STDIN (another bug), which results in running out of memory.
