Subject: [v2,0/2] tools: bpftool: add net attach/detach command to attach XDP prog
Date: Thu,  1 Aug 2019 17:11:31 +0900	[thread overview]
Message-ID: <20190801081133.13200-1-danieltimlee@gmail.com> (raw)

Currently, bpftool net only supports dumping progs attached on the
interface. To attach XDP prog on interface, user must use other tool
(eg. iproute2). By this patch, with `bpftool net attach/detach`, user
can attach/detach XDP prog on interface.

    $ ./bpftool prog
    ...
    208: xdp  name xdp_prog1  tag ad822e38b629553f  gpl
      loaded_at 2019-07-28T18:03:11+0900  uid 0
    ...
    $ ./bpftool net attach id 208 xdpdrv enp6s0np1
    $ ./bpftool net
    xdp:
    enp6s0np1(5) driver id 208
    ...
    $ ./bpftool net detach xdpdrv enp6s0np1
    $ ./bpftool net
    xdp:
    ...

While this patch only contains support for XDP, through `net
attach/detach`, bpftool can further support other prog attach types.

XDP attach/detach tested on Mellanox ConnectX-4 and Netronome Agilio.

Changes in v2:
  - command 'load/unload' changed to 'attach/detach' for the consistency
