2021-02-04vlib: increase the stats epoch only when necessaryMiklos Tirpak2-16/+72
When the counter vectors are validated and they are already long enough to fit the given index in memory, there is no need to increase the stats segment epoch. In this case, the counter vectors do not change as a result of the validation. This optimization is necessary for the case when the configuration is changed at multiple thousands per second rate. The counter vectors grow at the beginning and their size stabilizes after a while. Without this improvement, it can still take several seconds for a stats reader to succeed.

2021-01-15vlib: fix counter_will_expand predictionMiklos Tirpak1-6/+3
vlib_validate_combined_counter_will_expand() was calling _vec_resize_will_expand() with wrong arguments, which resulted in false return value. Apart from the initial call, it never indicated a vector resize. The callers relying on this function did not perform a barrier sync because of the wrong prediction even if the vector got extended by a subsequent vlib_validate_combined_counter() call. The fix introduces a new, simplified macro that is easier to call. vec_resize_will_expand() accepts the same arguments as vec_resize().

2020-12-15classify: add pcap/trace classfier mgmt API callsJon Loeliger4-10/+11
Add lookup/get/set API calls to manage both PCAP and Trace filtering Classifier tables. The "lookup" call may be used to identify a Classifier table within a chain of tables taht matches a particular mask vector. For efficiency, this call should be used to determine to which table a match vector should be added. The "get" calls return the first table within a chain (either a PCAP or the Trace) set of tables. The "set" call may be used to add a new table to one such chain. If the "sort_masks" flag is set, the tables within the chain are ordered such that the most-specific mask is first, and the least-specific mask is last. A call that "sets" a chain to ~0 will delete and free all the tables with a chain. The PCAP filters are per-interface, with "local0", (that is, sw_if_index == 0) holding the system-wide PCAP filter. The Classifier used a reference-counted "set" for each PCAP or trace filter that it stored. The ref counts were not used, and the vector of tables was only used temporarily to establish a sorted order for tables based on masks. None of that complexity was actually warranted, and where it was used, the same could be achieved more simply.

2020-11-04vlib: add postmortem pcap dispatch traceDave Barach5-14/+92
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.
