spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD

2023-07-25T15:13:49Z

The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch up to that fact and revert to their recommended match of BSD-2-Clause. Discussed with: pfg MFC After: 3 days Sponsored by: Netflix (cherry picked from commit 4d846d260e2b9a3d4d0a701462568268cbfe7a5b)

routing: add IPv6 fib validation procedure.

2021-09-07T21:02:58Z

Allow consistency validation of the inet6 fib based on rib data. Validation can be kicked off by loading test_lookup module and running sysctl net.route.test.run_inet6_scan=1 (cherry picked from commit cbfba56c45ab77303a3e25a82cf750043849760b)

routing: Use process fib instead of fib 0 when conducting tests.

2021-09-07T21:02:58Z

* Allow to do validation/performance tests by using process fib instead of default fib 0. * Print all validation errors instead of just the first one. (cherry picked from commit 4a77a9b6491093b9a8bb786a861ed74ddf156e8e)

tests: Revise FIB lookups per second benchmarking routines

2021-06-20T11:27:17Z

Fix a bug in the LPM SEQ benchmark (missing break inside a switch block) by restructuring the test loop, while introducing additional two synthetic test options: ANN: scan only the address space announced in current RIB REP: repeat lookups over several keys in a sliding window scheme The total of eight combinations of test options are now available through dedicated sysctl hooks.

Revise FIB lookups per second benchmarking routines.

2021-06-20T11:26:52Z

Add a LPS benchmark variant which introduces artificial dependencies between successive lookups. While here, instead of writing the results from the lookups to a huge array, add them to an accumulator, in a more lightweight attempt at preventing the CPU's OOO machinery from discarding the lookup results if they would be completely unused. net.route.test.run_lps_rnd measures LPS throughput with independent uniformly random keys net.route.test.run_lps_seq measures LPS throughput with uniformly random keys with artificial interdependencies Reviewed by: melifaro MFC after: 7 days Differential Revision: https://reviews.freebsd.org/D30096 (cherry picked from commit a43104ebe7630111d7e7debc56aacf49787dcf43)

Add IPv4 fib lookup performance tests with uniform keys.
