2020-08-13vlib: complain if workers are configured twiceVladimir Isaev1-1/+10

2020-08-13vlib: fix error when creating avf interface on SMP systemJieqiang Wang1-1/+13
On SMP architecture, '/sys/bus/pci/devices/<devices id>/numa_node' file will return -1 as a valid value if it does not have any NUMA node information. Using -1 as a valid node id to access data structures will cause memory issue. Fix the error by setting the value of numa_node to 0 if '/sys/bus/pci/devices/ <devices id>/numa_node' returns -1 and it is a SMP system.

2020-08-12vlib: 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.

2019-11-18vlib: 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.

2019-11-15vlib: 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.

2019-10-18vlib: 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.

2019-09-25interface: use the correct condition for checking if the pcap fd is openAndrew Yourtchenko1-1/+1
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.

2019-08-15vlib: copy trace_handle in vlib_buffer_copy/clone() functionsJohn Lo2-4/+2
Since vlib_buffer_copy() and vlib_buffer_clone() both preserve VLIB_BUFFER_IS_TRACED bit in flags field, it should also copy trace_handle which would add minimal overhead. Thus, callers of these functions do not have to call vlib_buffer_copy_trace_flags() to copy trace_handle.

2019-07-23vlib: address vlib_error_t scaling issueDave Barach6-38/+36
Encoding the vpp node index into the vlib_error_t as a 10-bit quantity limits us to 1K graph nodes. Unfortunately, a few nodes need 6 bit per-node error codes. Only a very few nodes have so many counters. It turns out that there are about 2K total error counters in the system, which is (approximately) the maximum error heap index. The current (index,code) encoding limits the number of interfaces to around 250, since each interface has two associated graph nodes and we have about 500 "normal, interior" graph node This patch adds an error-index to node-index map, so we can store error heap indices directly in the vlib_buffer_t.
