Title
netfilter: ipset: fix performance regression in swap operation
Summary
In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: fix performance regression in swap operation The patch "netfilter: ipset: fix race condition between swap/destroy and kernel side add/del/test", commit 28628fa9 fixes a race condition. But the synchronize_rcu() added to the swap function unnecessarily slows it down: it can safely be moved to destroy and use call_rcu() instead. Eric Dumazet pointed out that simply calling the destroy functions as rcu callback does not work: sets with timeout use garbage collectors which need cancelling at destroy which can wait. Therefore the destroy functions are split into two: cancelling garbage collectors safely at executing the command received by netlink and moving the remaining part only into the rcu callback.

Therefore the destroy\nfunctions are split into two: cancelling garbage collectors safely at\nexecuting the command received by netlink and moving the remaining\npart only into the rcu callback."

Therefore the destroy\nfunctions are split into two: cancelling garbage collectors safely at\nexecuting the command received by netlink and moving the remaining\npart only into the rcu callback."

Eric Dumazet se\u00f1al\u00f3 que simplemente llamar a las funciones de destrucci\u00f3n como devoluci\u00f3n de llamada de rcu no funciona: los conjuntos con tiempo de espera usan recolectores de basura que necesitan cancelarse en la destrucci\u00f3n y que pueden esperar. Por lo tanto, las funciones de destrucci\u00f3n se dividen en dos: cancelar los recolectores de basura de forma segura al ejecutar el comando recibido por netlink y mover la parte restante solo a la devoluci\u00f3n de llamada de rcu."

Therefore the destroy\nfunctions are split into two: cancelling garbage collectors safely at\nexecuting the command received by netlink and moving the remaining\npart only into the rcu callback."
