First is the patch to add IFLA_EVENT attribute to the netlink message. It supports only currently white-listed events. Like before, this is just an attribute that gets added to the rtnetlink message only when the messaged was generated as a result of a netdev event. In my case, this is necessary since I want to trap NETDEV_NOTIFY_PEERS event (also possibly NETDEV_RESEND_IGMP event) and perform certain actions in user space. This is not possible since the messages generated as a result of netdev events do not usually contain any changed data. They are just notifications. This patch exposes this notification type to userspace. Second, I remove duplicate messages that a result of a change to bonding options. If netlink is used to configure bonding options, 2 messages are generated, one as a result NETDEV_CHANGEINFODATA event triggered by bonding code and one a result of device state changes triggered by netdev_state_change (called from do_setlink). I will also update my patch to iproute that will show this data through 'ip monitor'. V4: * Removed the patch the removed NETDEV_CHANGENAME from event whitelist. It doesn't trigger duplicate messages since name changes can only be done while device is down and netdev_state_change() doesn't report changes while device is down. * Added a patch to clean-up duplicate messages on bonding option changes. V3: Rebased. Cleaned-up duplicate event. V2: Added missed events (from David Ahern) Vladislav Yasevich (2): rtnl: Add support for netdev event to link messages bonding: Prevent duplicate userspace notification drivers/net/bonding/bond_main.c | 3 +- drivers/net/bonding/bond_options.c | 27 +++++++++++++++-- include/linux/rtnetlink.h | 3 +- include/net/bond_options.h | 2 ++ include/uapi/linux/if_link.h | 11 +++++++ net/core/dev.c | 2 +- net/core/rtnetlink.c | 62 ++++++++++++++++++++++++++++++++------ 7 files changed, 96 insertions(+), 14 deletions(-) -- 2.7.4
