From: Yohei Kojima <[email protected]> This series fixes netdevsim's inconsistent behavior between carrier and link/unlink state.
More specifically, this fixes a bug that the carrier goes DOWN although two netdevsim were peered, depending on the order of peering and ifup. Especially in a NetworkManager-enabled environment, netdevsim test fails because of this. The first patch fixes the bug itself in netdevsim/bus.c by adding netif_carrier_on() into a proper function. The second patch adds a regression test for this bug. Changelog ========= v1 -> v2 - Rebase to the latest net/main - Separate TFO tests from this series - Separate netdevsim test improvement from this series - v1: https://lore.kernel.org/netdev/[email protected]/ Yohei Kojima (2): net: netdevsim: fix inconsistent carrier state after link/unlink selftests: netdevsim: add carrier state consistency test drivers/net/netdevsim/bus.c | 6 ++ .../selftests/drivers/net/netdevsim/peer.sh | 63 +++++++++++++++++++ 2 files changed, 69 insertions(+) -- 2.51.2
