  "message": "ipv4: Elide fib_validate_source() completely when possible.\n\nIf rpfilter is off (or the SKB has an IPSEC path) and there are not\ntclassid users, we don\u0027t have to do anything at all when\nfib_validate_source() is invoked besides setting the itag to zero.\n\nWe monitor tclassid uses with a counter (modified only under RTNL and\nmarked __read_mostly) and we protect the fib_validate_source() real\nwork with a test against this counter and whether rpfilter is to be\ndone.\n\nHaving a way to know whether we need no tclassid processing or not\nalso opens the door for future optimized rpfilter algorithms that do\nnot perform full FIB lookups.\n\nSigned-off-by: David S.
