So, you want to address the issue raised by following patch?


I would still like to stick to my proposal, that is to introduce a
new API to do the permission change at anytime, if we end up with
wanting to introduce a new API.

Could you name a specific example?

BTW, JFYI, since 16.07, DPDK supports client mode. It's QEMU (acting
as the server) will create the socket file. I guess that would diminish
(or even avoid?) the permission pain that DPDK acting as server brings.
I doubt the API to do the permission change is really needed then.
