Hannes Frederic Sowa b064d0d88a ovs: limit ovs recursions in ovs_execute_actions to not corrupt stack ... It was seen that defective configurations of openvswitch could overwrite the STACK_END_MAGIC and cause a hard crash of the kernel because of too many recursions within ovs. This problem arises due to the high stack usage of openvswitch. The rest of the kernel is fine with the current limit of 10 (RECURSION_LIMIT). We use the already existing recursion counter in ovs_execute_actions to implement an upper bound of 5 recursions.
