Which statement about the total slab size is correct?

  • A The total slab size of the ip6_session slab is 1472 kB and is associated with the kernel.
  • B The total slab size of the ip_session slab is 14080 kB and is associated with the user space.
  • C The total slab size of the UDPv6 slab is 14080 kB and is associated with the user space.
  • D The total slab size of the tcp_session slab is 7500 kB and is associated with the kernel.
Explanation

A slab cache is kernel-managed memory. The tcp_session entry has 5 objects with an object size of 1500, producing a total of 7500; it is therefore associated with the kernel. FortiOS documents diagnose hardware sysinfo slab as displaying memory-allocation information.
