2020-11-05tap: allow change of carrier state on hostMatthew Smith4-0/+45
Type: feature Add a function to adjust the link state of the host side of a tap interface. If an application (e.g. route protocol daemons) running on the host uses netlink to monitor interface state, a plugin could use this function to communicate a loss of connectivity to the application by making the interface appear to go down. Requires a somewhat recent kernel. E.g. it does not have any effect on CentOS 7 but it works on CentOS 8.

2020-11-04vlib: add postmortem pcap dispatch traceDave Barach6-17/+95
Inspired by a real-life conundrum: scenario X involves a vpp crash in ip4-load-balance because vnet_buffer(b)->ip.adj_index[VLIB_TX] is (still) set to ~0. The problem takes most of a day to occur, and we need to see the broken packet's graph trajectory, metadata, etc. to understand the problem. Fix a signed/unsigned ASSERT bug in vlib_get_trace_count(). Rename elog_post_mortem_dump() -> vlib_post_mortem_dump(), add dispatch trace post-mortem dump. Add FILTER_FLAG_POST_MORTEM so we can (putatively) capture a ludicrous number of buffer traces, without actually using more than one dispatch cycle's worth of memory.

It is likely that the EPOLLOUT is meant for the previous owner of the same file descriptor number which memif recycled and memif RX did not expect to receive an EPOLLOUT. For defensive play, we create a dummy callback function to ignore the EPOLLOUT instead of crashing.
