net: sched: copy tunnel info when setting flow_action entry->tunnel
In order to remove dependency on rtnl lock, modify tc_setup_flow_action() to copy tunnel info, instead of just saving pointer to tunnel_key action tunnel info. This is necessary to prevent concurrent action overwrite from releasing tunnel info while it is being used by rtnl-unlocked driver. Implement helper tcf_tunnel_info_copy() that is used to copy tunnel info with all its options to dynamically allocated memory block. Modify tc_cleanup_flow_action() to free dynamically allocated tunnel info. Signed-off-by: Vlad Buslov <vladbu@mellanox.com> Acked-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.
