Message-Id: <20231208194523.312416-3-thinker.li@gmail.com> Date: Fri, 8 Dec 2023 11:45:23 -0800 From: thinker.li@...il.com To: netdev@...r.kernel.org, martin.lau@...ux.dev, kernel-team@...a.com, davem@...emloft.net, kuba@...nel.org, pabeni@...hat.com, dsahern@...nel.org, edumazet@...gle.com Cc: sinquersw@...il.com, kuifeng@...a.com, Kui-Feng Lee <thinker.li@...il.com> Subject: [PATCH net-next v2 2/2] selftests: fib_tests: Add tests for toggling between w/ and w/o expires. From: Kui-Feng Lee <thinker.li@...il.com> Make sure that toggling routes between w/ expires and w/o expires works properly with GC list. When a route with expires is replaced by a permanent route, the entry should be removed from the gc list. When a permanent routes is replaced by a temporary route, the new entry should be added to the gc list. The new tests check if these basic operators work properly.
