ethtool: fix reference leak in ethnl_set_privflags()

2020-03-30T05:32:36+00:00

Andrew noticed that some handlers for *_SET commands leak a netdev reference if required ethtool_ops callbacks do not exist. One of them is ethnl_set_privflags(), a simple reproducer would be e.g. ip link add veth1 type veth peer name veth2 ethtool --set-priv-flags veth1 foo on ip link del veth1 Make sure dev_put() is called when ethtool_ops check fails.

ethtool: add PRIVFLAGS_NTF notification

2020-03-12T22:32:33+00:00

Send ETHTOOL_MSG_PRIVFLAGS_NTF notification whenever private flags of a network device are modified using ETHTOOL_MSG_PRIVFLAGS_SET netlink message or ETHTOOL_SPFLAGS ioctl request. Signed-off-by: Michal Kubecek Signed-off-by: David S. Miller

ethtool: set device private flags with PRIVFLAGS_SET request

2020-03-12T22:32:33+00:00

Implement PRIVFLAGS_SET netlink request to set private flags of a network device. These are traditionally set with ETHTOOL_SPFLAGS ioctl request. Signed-off-by: Michal Kubecek Reviewed-by: Jakub Kicinski Signed-off-by: David S. Miller

ethtool: provide private flags with PRIVFLAGS_GET request
