This adds memory and cpu costs. config NET_NS_REFCNT_TRACKER bool "Enable networking namespace refcount tracking" depends on DEBUG_KERNEL && STACKTRACE_SUPPORT && NET select REF_TRACKER default n help Enable debugging feature to track netns references. This adds memory and cpu costs. config DEBUG_NET bool "Add generic networking debug" depends on DEBUG_KERNEL && NET help Enable extra sanity checks in networking. This is mostly used by fuzzers, but is safe to select. config DEBUG_NET_SMALL_RTNL bool "Add extra per-netns mutex inside RTNL" depends on DEBUG_KERNEL && NET && LOCK_DEBUGGING_SUPPORT select PROVE_LOCKING default n help rtnl_lock() is being replaced with rtnl_net_lock() that acquires the global RTNL and a small per-netns RTNL mutex. During the conversion, rtnl_net_lock() just adds an extra mutex in every RTNL scope and slows down the operations. Once the conversion completes, rtnl_lock() will be removed and rtnetlink will gain per-netns scalability.
