The kernel has gained support for exporting some information via netlink. Use this when available, rather than debugfs.

If netlink is not available, or the information is not yet available via netlink, batctl will fall back to debugfs.

Signed-off-by: Andrew Lunn andrew@lunn.ch --- v2: Verify mandatory attributes are returned by the kernel, and that they have the expected size.

v3: Use libnl to perform more verification Add originator header checkpatch cleanup

v4: Add the missing netlink.h to the patch

v5: Handle -i flag to originators Handle -u and -m flag to tg and tl Fix type of BATADV_ATTR_THROUGHPUT --- Makefile | 13 +- batman_adv.h | 111 +++++++ debug.c | 22 +- debug.h | 4 +- functions.c | 11 + functions.h | 2 + main.h | 1 + netlink.c | 1050 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ netlink.h | 40 +++ 9 files changed, 1250 insertions(+), 4 deletions(-) create mode 100644 batman_adv.h create mode 100644 netlink.c create mode 100644 netlink.h
