2020-10-06ethtool: link up ethnl_header_policy as a nested policyJakub Kicinski1-2/+4
To get the most out of parsing by the core, and to allow dumping full policies we need to specify which policy applies to nested attrs. For headers it's ethnl_header_policy. $ sed -i 's@\(ETHTOOL_A_.*HEADER\].*=\) { .type = NLA_NESTED },@\1\n\t\tNLA_POLICY_NESTED(ethnl_header_policy),@' net/ethtool/* Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

2020-10-06ethtool: trim policy tablesJakub Kicinski1-7/+2
Since ethtool uses strict attribute validation there's no need to initialize all attributes in policy tables. 0 is NLA_UNSPEC which is going to be rejected. Remove the NLA_REJECTs. Similarly attributes above maxattrs are rejected, so there's no need to always size the policy tables to ETHTOOL_A_..._MAX. v2: - new patch Suggested-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

2020-10-06ethtool: wire up set policies to opsJakub Kicinski1-8/+3
Similarly to get commands wire up the policies of set commands to get parsing by the core and policy dumps. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-10-06ethtool: wire up get policies to opsJakub Kicinski1-4/+2
Wire up policies for get commands in struct nla_policy of the ethtool family. Make use of genetlink code attr validation and parsing, as well as allow dumping policies to user space. For every ETHTOOL_MSG_*_GET: - add 'ethnl_' prefix to policy name - add extern declaration in net/ethtool/netlink.h - wire up the policy & attr in ethtool_genl_ops[]. - remove .request_policy and .max_attr from ethnl_request_ops. Obviously core only records the first "layer" of parsed attrs so we still need to parse the sub-attrs of the nested header attribute. v2: - merge of patches 1 and 2 from v1 - remove stray empty lines in ops - also remove .max_attr Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

2020-03-29ethtool: fix reference leak in ethnl_set_privflags()Michal Kubecek1-1/+3
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.

2020-03-12ethtool: add PRIVFLAGS_NTF notificationMichal Kubecek1-0/+3
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 <mkubecek@suse.cz> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-03-12ethtool: set device private flags with PRIVFLAGS_SET requestMichal Kubecek1-0/+70
