In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: CT: Fix cleanup of CT before cleanup of TC ct rules CT cleanup assumes that all tc rules were deleted first, and so is free to delete the CT shared resources (e.g the dr_action fwd_action which is shared for all tuples). But currently for uplink, this is happens in reverse, causing the below trace. CT cleanup is called from: mlx5e_cleanup_rep_tx()->mlx5e_cleanup_uplink_rep_tx()-> mlx5e_rep_tc_cleanup()->mlx5e_tc_esw_cleanup()-> mlx5_tc_ct_clean() Only afterwards, tc cleanup is called from: mlx5e_cleanup_rep_tx()->mlx5e_tc_ht_cleanup() which would have deleted all the tc ct rules, and so delete all the offloaded tuples. Fix this reversing the order of init and on cleanup, which will result in tc cleanup then ct cleanup.
