Hi, Three bug fixes by Shay in the mlx5 LAG subsystem. Patch 1 fixes an off-by-one in the error rollback path of mlx5_lag_create_single_fdb_filter(): the loop started from the failed index i, potentially operating on uninitialized state or double-tearing-down an entry that had already self-rolled-back. The rollback should start from i - 1. Patch 2 fixes a hang in mlx5_mpesw_work(): when mlx5_lag_get_devcom_comp() returns NULL the function returned early without calling complete(), blocking any caller waiting on mpesww->comp indefinitely. Patch 3 fixes a kernel crash during teardown when mlx5_lag_get_dev_seq() returns an error because no device is marked as master or the peer is no longer in the LAG. The peer flow cleanup is now skipped instead of proceeding with a bad pointer. This series by Shay fixes three bugs in the mlx5 LAG subsystem. Regards, Tariq V2: - Rebase. - Patch 3: simplify to a single 'continue' on seq lookup failure.
