It worked back then when the kernel created dynamic contexts for unspecified context IDs. This feature was removed a long time ago, so you basically need to specify a static context ID to the kernel. Userspace tools normally work around that by emulating the dynamic context selection and sending a static ID to the kernel, but of course, in an explicit invocation like the chbind, this cannot be done easily. Solution: imply specify an unused context ID yourself. chbind --nid 999 --ip 192.168.4.167 ip a l will do what you want, if the network context with the number 999 does not exist before you call it.
