Subject: [PATCH net-next 0/2] net: control the length of the altname list

Count the memory used for altnames and don't let user
overflow the property nlattr. This was reported by George:
https://lore.kernel.org/all/3e564baf-a1dd-122e-2882-ff143f7eb578@gmail.com/

Targeting net-next because I think we generally don't consider
tightening "root controlled" memory accounting to be a fix.
There's also some risk of breakage.

Jakub Kicinski (2):
  net: account alternate interface name memory
  net: limit altnames to 64k total
