Hi! This series wires up ethtool policies to ops, so they can be dumped to user space for feature discovery.
First patch wires up GET commands, and second patch wires up SETs. The policy tables are trimmed to save space and LoC. Next - take care of linking up nested policies for the header (which is the policy what we actually care about). And once header policy is linked make sure that attribute range validation for flags is done by policy, not a conditions in the code. New type of policy is needed to validate masks (patch 6). Netlink as always staying a step ahead of all the other kernel API interfaces :) v2: - merge patches 1 & 2 -> 1 - add patch 3 & 5 - remove .max_attr from struct ethnl_request_ops Jakub Kicinski (7): ethtool: wire up get policies to ops ethtool: wire up set policies to ops ethtool: trim policy tables ethtool: link up ethnl_header_policy as a nested policy netlink: create helpers for checking type is an int netlink: add mask validation ethtool: specify which header flags are supported per command include/net/netlink.h | 27 +++++--- include/uapi/linux/netlink.h | 2 + lib/nlattr.c | 36 ++++++++++ net/ethtool/bitset.c | 26 ++++---- net/ethtool/cabletest.c | 41 ++++-------- net/ethtool/channels.c | 35 ++-------- net/ethtool/coalesce.c | 45 ++----------- net/ethtool/debug.c | 24 ++----- net/ethtool/eee.c | 32 +++------ net/ethtool/features.c | 30 ++------- net/ethtool/linkinfo.c | 30 ++------- net/ethtool/linkmodes.c | 32 ++------- net/ethtool/linkstate.c | 14 +--- net/ethtool/netlink.c | 124 +++++++++++++++++++++++++---------- net/ethtool/netlink.h | 35 ++++++++-- net/ethtool/pause.c | 27 ++------ net/ethtool/privflags.c | 24 ++----- net/ethtool/rings.c | 35 ++-------- net/ethtool/strset.c | 25 +++---- net/ethtool/tsinfo.c | 13 +--- net/ethtool/tunnels.c | 42 ++++-------- net/ethtool/wol.c | 24 ++----- net/netlink/policy.c | 8 +++ 23 files changed, 317 insertions(+), 414 deletions(-) -- 2.26.2
