2017-06-02vhost: add debug vhost-user on | off CLISteven2-20/+59
Add runtime debug vhost-user on | off CLI to facilitate troubleshooting. This feature is needed to avoid recompiling the code to debug vhost issues. The debugging messages should not be on the data path to avoid performance hit. Change-Id: I4c40f65dbb222557cba3fb8706fa3b7b62eec95f Signed-off-by: Steven <sluong@cisco.com>

- inline the FIB lookup function; this requires access to the bihash, so for files that use more than one type this casues problems. those files that include ip6_fib.h unnecessarily have been updated - better use of the feature arcs. ip6-lookup and interface-output are now sentinels (end-node-index in the cm speak) rather than enabled features.

2017-05-23ARP/ND entries for the same address on different interfaces (VPP-848)Neale Ranns18-735/+1194
there are, intentionally, no validation checks in the ARP/ND code to prevent an ARP/ND entry from being installed for an address that is not local to the interface's sub-net. This is ok, since the adjacency/FIB code is designed to handle this case using the 'refinement' criteria - i.e. only installing a FIB entry for the address if the address 'refines' (i.e. is more specific than) the interface's sub-net. However, the refinement criteria currently operates on the FIB entry's prefix (which is a /32, so on the address) and not on the next-hop in the path. So, enter multiple ARP entries for the same address on different links, and this refinement criteria uses only the last added path, and so will remove the FIB entry should the ARP entries be added in the 'wrong' order. This fix updates the refinement criteria to work on each path of the FIB entry. The entry is installed if one of the paths refines the covers and only paths refining the cover contribute forwarding. Per-path refinement checks are stored in path-extensions. The patch is rather large as path-extension, which were previously used only for out-going MPLS labels, have been generalized.

2017-05-22vhost: migrate to use device infra for worker thread assignment, rx-mode.Steven4-484/+336
and add adaptive mode support to receive queue - Migrate vhost to use device infra which does the interface/queue to worker thread assignment. - Retire vhost thread CLI and corresponding code which assigns interface/queue to worker thread. set interface placement should be used instead to customize the interface/queue to worker thread assignment. - Retire vhost interrupt/polling option when creating vhost-user interface. Instead, set interface rx-mode should be used. - Add code in vnet_device_input_unassign_thread to change the node state to interrupt if the last polling interface has left the worker thread for the device of the corresponding interface/queue. - Add adaptive mode support. The node state is set to interrupt initially. When the scheduler detects a burst of traffic, it switches the input node to polling. Then we inform the device that we don't need interrupt notification. When the traffic subsides, the scheduler switches the input node back to interrupt. Then we immediately tell the driver that we want interrupt notification again. - Remove some duplicate code in vlib/main.c Change-Id: Id19bb1b9e50e6521c6464f470f5825c26924d3a8 Signed-off-by: Steven <sluong@cisco.com>

2017-05-20vhost: buffers leak and interface disable upon vring descriptor out of mmapSteven1-16/+9
When processing a vring descriptor which is outside of mmap, we disable the interface and spit a message to shut/no shut the interface. This is not practical as application using vhost cannot constantly checking the logs and do the recovery. The proposed fix is to log an error, like other errors that we encounter. The other bug is buffer leak in the function rewind. At the end of the while loop when b_current != b_head, we still have to give back 1 more buffer or add 1 to rx_buffers_len.

2017-05-17vhost: bad packet assembled from descriptor chainingSteven1-1/+2
When the descriptor is chained via multiple parts, vhost is supposed to reassemble the different parts to form a packet prior to passing the packet to the next input node. However, bad packet was seen, having bad ethertype, source, and destination mac addresses. The problem was due to the destination pointer not being incremented as each chain is processed. THe result was the first chain is copied to the beginning of the buffer, the next chain is copied, then the last chain is also copied to the beginning of the buffer. As a result, the ethertype, source and destination mac, etc, are being overwritten by the very last chain of the descriptor.
